3 Use functions and constants to manipulate Lisp_Save_Value objects.
4 This replaces code that used macros and strings and token-pasting.
5 The change makes the C source a bit easier to follow,
6 and shrinks the Emacs executable a bit.
7 * alloc.c: Verify some properties of Lisp_Save_Value's representation.
8 (make_save_value): Change 1st arg from string to enum. All callers
11 (mark_object): Use if, not #if, for GC_MARK_STACK.
12 * lisp.h (SAVE_VALUEP, XSAVE_VALUE, XSAVE_POINTER, XSAVE_INTEGER)
13 (XSAVE_OBJECT): Now functions, not macros.
14 (STRING_BYTES_BOUND): Now just a macro, not a constant too;
15 the constant was never used.
16 (SAVE_SLOT_BITS, SAVE_VALUE_SLOTS, SAVE_TYPE_BITS, SAVE_TYPE_INT_INT)
17 (SAVE_TYPE_INT_INT_INT, SAVE_TYPE_OBJ_OBJ, SAVE_TYPE_OBJ_OBJ_OBJ)
18 (SAVE_TYPE_OBJ_OBJ_OBJ_OBJ, SAVE_TYPE_PTR_INT, SAVE_TYPE_PTR_OBJ)
19 (SAVE_TYPE_PTR_PTR, SAVE_TYPE_PTR_PTR_OBJ, SAVE_TYPE_MEMORY):
21 (struct Lisp_Save_Value): Replace members area, type0, type1, type2,
22 type3 with a single member save_type. All uses changed.
23 (save_type, set_save_pointer, set_save_integer): New functions.
24 * print.c (PRINTX): Remove.
26 * alloc.c: Remove redundant static declarations.
28 2013-03-20 Dmitry Antipov <dmantipov@yandex.ru>
30 * window.h (struct window): Convert left_col, top_line, total_lines
31 and total_cols from Lisp_Objects to integers. Adjust comments.
32 (wset_left_col, wset_top_line, wset_total_cols, wset_total_lines):
34 (WINDOW_TOTAL_COLS, WINDOW_TOTAL_LINES, WINDOW_LEFT_EDGE_COL)
35 (WINDOW_TOP_EDGE_LINE): Drop Lisp_Object to integer conversion.
36 * dispnew.c, frame.c, w32fns.c, window.c, xdisp.c, xfns.c:
37 Adjust users where appropriate.
39 2013-03-20 Dmitry Antipov <dmantipov@yandex.ru>
41 * frame.h (struct frame): Drop resx and resy because the same data is
42 available from window system-specific output context. Adjust users.
43 (default_pixels_per_inch_x, default_pixels_per_inch_y): New
44 functions to provide defaults when no window system available.
45 (FRAME_RES_X, FRAME_RES_Y): New macros.

121 * coding.c (detect_ascii): New function.
122 (detect_coding): Set coding->head_ascii and coding->eol_seen only
123 when the source bytes are actually scanned. On detecting for
124 coding_category_utf_8_auto, call detect_ascii instead of scanning
125 source bytes directly.
126 (produce_chars): Call insert_from_gap with the new arg 0.
127 (encode_coding): Likewise.
128 (decode_coding_gap): Control ASCII optimization by the variable

151 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
152 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE

156 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
159 2013-03-13 Daniel Colascione <dancol@dancol.org>
161 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
162 too so that these builds can use Cygwin's file conversion
163 functions. (We've been building and linking cygw32.o all along
164 and just not using it.)
166 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
168 File synchronization fixes (Bug#13944).
169 * Makefile.in (LIB_FDATASYNC): New macro.
171 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
172 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
173 Don't worry about HAVE_FSYNC, since a substitute fsync is
174 available if the system lacks one.
175 (Fwrite_regin): Retry fsync if interrupted.
177 2013-03-13 Eli Zaretskii <eliz@gnu.org>
179 * w32term.c (w32_read_socket): If the Emacs frame is being
180 activated, call w32fullscreen_hook, to make sure the new frame
181 dimensions are in effect. (Bug#13937)
183 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
185 * xdisp.c (init_iterator): Simplify because both character and byte
186 positions are either specified or -1. Add eassert. Adjust comment.
187 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
188 character and byte positions can be obtained from marker.

207 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
208 Include <sys/param.h> unconditionally, as that works elsewhere and
209 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
210 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
213 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

242 common file dialog code.
244 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
245 can just use du like other systems.
247 * coding.c (from_unicode_buffer): Declare.
248 * coding.c (from_unicode_buffer): Implement.
250 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

291 (adjust_after_insert): Call adjust_after_replace with the new arg
294 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
296 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
297 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
298 from Elisp via unread-command-events.
300 * keyboard.c (access_keymap_keyremap): Accept nil return value from
301 functions to mean "no change".
303 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
305 region-cache.c, scroll.c, search.c: Use bool for booleans.
306 * lisp.h (compile_pattern):
307 * scroll.c (do_scrolling, do_direct_scrolling):
308 * search.c (struct regexp_cache, compile_pattern_1)
309 (compile_pattern, string_match_1, search_command)
310 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
311 (search_regs_saved, Fregexp_quote):
312 Use bool for boolean.
313 * region-cache.c (region_cache_forward, region_cache_backward):
314 Fix comments to match code: these functions return int, not boolean.
316 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
318 * search.c (find_newline): Accept start and end byte positions
319 as arguments and allow -1 if not known.

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

434 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
436 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
437 * sysdep.c (list_system_processes)
438 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
439 Make it a stub in this case; otherwise the build might fail,
440 and this code hasn't been tested on such hosts anyway.
441 Problem reported by Nelson H. F. Beebe in
442 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
443 and analyzed by Jérémie Courrèges-Anglas in
444 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
446 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
448 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
449 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
450 (get_visually_first_element, move_it_vertically_backward): Ajust users.
451 * bidi.c (bidi_find_paragraph_start): Likewise.
452 * indent.c (vmotion): Likewise.
454 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
456 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
457 * filelock.c: Include <c-ctype.h>.
458 (MAX_LFINFO): New top-level constant.
459 (lock_info_type): Remove members pid, boot_time. Add members at,
460 dot, colon. Change user member to be the entire buffer, not a
461 pointer. This allows us to handle the case where a foreign
462 pid or boot time exceeds the local range. All uses changed.
463 (LINKS_MIGHT_NOT_WORK): New constant.
464 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
465 (defined_WINDOWSNT): Remove.
466 (MAKE_LOCK_NAME, file_in_lock_file_name):
467 Always use .#FILE (not .#-FILE) for the file lock,
468 even if it is a regular file.
469 (rename_lock_file): New function.
470 (create_lock_file): Use it.
471 (create_lock_file, read_lock_data):
472 Prefer a symbolic link for the lock file, falling back on a
473 regular file if symlinks don't work. Do not try to create
474 symlinks on MS-Windows, due to security hassles. Stick with
475 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
476 link, rename, unlink, mkstemp) when creating locks, as a GNUish
477 host may be using a Windowsish file system, and cannot use
478 MS-Windows-only system calls. Fall back on mktemp if mkstemp
479 doesn't work. Don't fail merely because of a symlink-contents
480 length limit in the current file system; fall back on regular
481 files. Increase the symlink contents length limit to 8 KiB, this
482 should be big enough for any real use and doesn't crunch the
484 (create_lock_file, lock_file_1, read_lock_data):
485 Simplify allocation of lock file buffers now that they fit in 8 KiB.
486 (lock_file_1): Return error number, not bool. All callers changed.
487 (ELOOP): New macro, if not already defined.
488 (read_lock_data): Return size of lock file contents, not Lisp object.
489 All callers changed. Handle a race condition if some other process
490 replaces a regular-file lock with a symlink lock or vice versa,
491 while we're trying to read the lock.
492 (current_lock_owner): Parse contents more carefully, to help avoid
493 confusing a regular-file lock with some other application's use
494 of the file. Check for lock file contents being too long, or
495 not parsing correctly.
496 (current_lock_owner, lock_file):
497 Allow foreign pid and boot times that exceed the local range.
498 (current_lock_owner, lock_if_free, lock_file):
499 Simplify allocation of lock file contents.
500 * w32.c (sys_rename_replace): New function, containing most of
501 the contents of the old sys_rename.
502 (sys_rename): Use it.
503 (fchmod): New dummy function.
504 * w32.h (sys_rename_replace, fchmod): New decls.
506 2013-03-05 Eli Zaretskii <eliz@gnu.org>
508 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
509 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
510 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
511 <dmantipov@yandex.ru>.
513 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
515 * composite.c (get_composition_id, fill_gstring_header):
516 Use make_uninit_vector where appropriate.
517 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
518 * xselect.c (clean_local_selection_data): Likewise.
520 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
522 Fix misuse of ImageMagick that caused core dump (Bug#13846).
523 * image.c (imagemagick_load_image): Calculate height and width
524 after flattening the image, not before.
526 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
528 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
529 * ftfont.c (ftfont_shape_by_flt): Likewise.
530 * w32uniscribe.c (uniscribe_shape): Likewise.
532 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
534 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
535 The old approach, which fell back on DIR/.#FILE.0 through
536 DIR/.#FILE.9, had race conditions that could not be easily fixed.
537 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
538 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
539 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
540 because the locking mechanism was never reliable in that case).
541 This patch fixes this and other bugs discovered by a code
542 inspection that was prompted by
543 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
544 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
545 to avoid interoperability problems between the MS-Windows and
546 non-MS-Windows implementations. MS-Windows and non-MS-Windows
547 instances of Emacs now ignore each others' locks.
548 * filelock.c (defined_WINDOWSNT): New constant.
549 (MAKE_LOCK_NAME, fill_in_lock_file_name):
550 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
551 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
552 regular files on MS-Windows hosts.
553 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
554 Use SAFE_ALLOCA to avoid problems with long file names.
555 (MAX_LFINFO): Now a local constant, not a global macro.
556 (IS_LOCK_FILE): Remove.
557 (lock_file_1): Don't inspect errno if symlink call succeeds;
559 (lock_file): Document that this function can return if lock
561 (lock_file): Don't access freed storage.
563 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
565 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
567 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
569 * textprop.c: Use bool for booleans.
570 (validate_interval_range, Fadd_text_properties)
571 (Fremove_text_properties): Prefer bool to int when either works.
573 2013-03-02 Eli Zaretskii <eliz@gnu.org>
575 * textprop.c (Fadd_text_properties, Fremove_text_properties):
576 If the interval tree changes as a side effect of calling
577 modify_region, re-do processing starting from the call to
578 validate_interval_range. (Bug#13743)
580 2013-02-28 Eli Zaretskii <eliz@gnu.org>
582 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
585 2013-02-27 Eli Zaretskii <eliz@gnu.org>
587 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
588 _SH_DENYRW flag, instead of emacs_open, to deny any other process
589 access to the lock file until it is written and closed.
592 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
594 * callint.c (Qcall_interactively):
595 * macros.c (Qexecute_kbd_macro):
598 2013-02-26 Bastien Guerry <bzg@gnu.org>
600 * window.c (Frecenter): Tiny docstring enhancement.
602 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
604 Minor textprop integer cleanup.
605 * intervals.h, textprop.c (add_text_properties_from_list):
606 Return void, not int, since nobody uses the return value.
607 * textprop.c (validate_plist, add_properties, remove_properties)
608 (Fadd_text_properties):
609 Don't assume list length fits in int.
610 (interval_has_all_properties, interval_has_some_properties)
611 (interval_has_some_properties_list, add_properties, remove_properties)
612 (Fadd_text_properties, Fremove_text_properties)
613 (Fremove_list_of_text_properties, text_property_stickiness):
614 Use bool for booleans.
615 (Fadd_text_properties, Fremove_text_properties):
616 (Fremove_list_of_text_properties):
617 Reindent do-while as per GNU style.
619 2013-02-25 Eli Zaretskii <eliz@gnu.org>
621 Implement CLASH_DETECTION for MS-Windows.
623 * filelock.c [WINDOWSNT]: Include w32.h.
624 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
625 function of that name. Up-case the macro arguments.
626 (IS_LOCK_FILE): New macro.
627 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
628 (create_lock_file): New function, with body extracted from
630 [WINDOWSNT]: Implement lock files by writing a regular file with
631 the lock information as its contents.
632 (read_lock_data): New function, on Posix platforms just calls
634 [WINDOWSNT]: Read the lock info from the file.
635 (current_lock_owner): Call read_lock_data instead of calling
636 emacs_readlinkat directly.
637 (lock_file) [WINDOWSNT]: Run the file name through
640 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
641 just check if the process by that PID exists.
643 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
644 also present, as doing so will fail to error out if the file
647 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
649 * textprop.c (Fadd_text_properties, Fremove_text_properties)
650 (Fremove_list_of_text_properties): Skip all of the intervals in
651 the region between START and END that already have resp. don't
652 have the requested properties, not just the first one.
653 Add assertions that the loop afterwards always modifies the
654 properties. (Bug#13743)
656 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
658 * callint.c (Fcall_interactively): Use the right lexical environment

662 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
664 Simplify data_start configuration (Bug#13783).
665 This is a followon simplification to the fix for Bug#13650.
666 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
667 (START_FILES): Remove. All uses removed.
668 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
669 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
670 (buildobj.h): Use it.
671 ($(ALLOBJS)): Depend on globals.h.
672 (temacs$(EXEEXT)): Use $(ALLOBJS).
673 * autodeps.mk (ALLOBJS): Move to Makefile.in.
674 * deps.mk (vm-limit.o):

677 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
678 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
679 [__GNUC__ && !ORDINARY_LINK]: Remove.
680 * mem-limits.h, pre-crt0.c: Remove.
681 * unexaix.c, unexcoff.c: Don't include mem-limits.h.

683 (make_hdr): Use DATA_START instead of start_of_data.
684 * vm-limit.c: Move most of mem-limits.h's contents here.
685 (data_start): New decl. It's OK if this is approximate,
686 so simplify-away some unnecessary exactness.
687 (POINTER): Remove; all uses removed.
688 (data_space_start): Now char *, to avoid casts.
689 (exceeds_lisp_ptr): New function, replacing the old
690 EXCEEDS_LISP_PTR macro. All uses changed.
691 (check_memory_limits): Simplify and remove casts.
692 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
693 (memory_warnings): Use data_start instead of start_of_data.
695 2013-02-24 Andreas Schwab <schwab@linux-m68k.org>
697 * xdisp.c (set_message): Only check for debug-on-message if STRING
698 is a string. (Bug#13797)
700 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
702 Fix regression introduced by July 10 filelock.c patch.
703 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
704 2012-07-10 patch to this file. Reported by Eli Zaretskii in
705 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
706 and diagnosed by Andreas Schwab in
707 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.

711 Assume C89 or better.
712 * ralloc.c (SIZE, POINTER, NIL):
713 * vm-limit.c (POINTER):
714 Remove, replacing all uses with C89 equivalents. These old
715 symbols were present only for porting to pre-C89 platforms.
717 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
719 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
720 This avoids warning messages reported as part of Bug#13546.
722 2013-02-21 Ken Brown <kbrown@cornell.edu>

730 * keyboard.c (Qcommand_execute): New var.
731 (command_loop_1, read_char): Use it.
732 (Fcommand_execute): Remove, replace by an Elisp implementation.
733 (syms_of_keyboard): Adjust accordingly.
735 2013-02-19 Daniel Colascione <dancol@dancol.org>
737 * sheap.c (report_sheap_usage): Use message, not message1, so
738 that we don't try to create a buffer while we're in the middle
739 of dumping Emacs. Explain why.
741 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
743 * search.c (find_newline): Return byte position in bytepos.
745 (find_next_newline_no_quit, find_before_next_newline):
746 Add bytepos argument.

752 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start):
753 (get_visually_first_element, move_it_vertically_backward):
754 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
756 2013-02-19 Eli Zaretskii <eliz@gnu.org>
758 * w32proc.c (new_child): Avoid leaking handles if the subprocess
759 resources were not orderly released.
761 2013-02-17 Eli Zaretskii <eliz@gnu.org>
763 * xdisp.c (x_draw_vertical_border): For a window that is neither
764 the leftmost nor the rightmost, redraw both the left and the right
765 vertical borders. (Bug#13723)

787 * w32.c (sys_chown): Remove unused function.
789 * w32term.c <input_signal_count>: Declare 'volatile'
790 unconditionally. (Bug#9066)
792 * w32.c (set_errno): Reset h_errno and don't set it to any other
793 value. Set errno instead.
794 (check_errno): Reset h_errno.
795 (sys_socket, socket_to_fd, sys_bind, sys_connect)

809 when auto-save-timeout is less than 4. (Bug#13720)
811 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

819 (socket_to_fd): Add assertion against indexing fd_info[] with a
820 value that is out of bounds.
821 (sys_accept): If fd is negative, do not set up the child_process
822 structure for reading.

838 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
840 Fix AIX port (Bug#13650).
841 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
842 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
843 was #undeffed earlier, so it cannot be used as a macro here.
844 Use the constant and not the macro.
846 2013-02-15 Eli Zaretskii <eliz@gnu.org>
848 * w32proc.c (new_child): If no vacant slots are found in
849 child_procs[], make another pass looking for slots whose process
850 has exited or died. (Bug#13546)
852 * w32.c (sys_pipe): When failing due to file descriptors above
853 MAXDESC, set errno to EMFILE.
854 (_sys_read_ahead): Update cp->status when failing to read serial
855 communications input, so that the status doesn't stay at
856 STATUS_READ_IN_PROGRESS. (Bug#13546)
858 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
860 * gtkutil.c (tb_size_cb): New function.
861 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
863 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
865 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
868 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
870 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
872 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
874 * font.c (font_range): Add pos_byte argument. Adjust comment
876 * font.h (font_range): Adjust prototype.
877 * composite.c (autocmp_chars): Pass byte position to font_range.
878 Break long line. Remove useless prototype and format comment.
880 2013-02-13 Glenn Morris <rgm@gnu.org>
882 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
884 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
886 Improve AIX port some more (Bug#13650).
887 With this, it should be as good as it was in 23.3, though it's
888 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
889 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
890 * unexaix.c (start_of_text): Remove.
891 (_data, _text): Declare as char[], not int, as AIX manual suggests.
892 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
893 (orig_load_scnptr, orig_data_scnptr):
894 Now off_t, not long, since they are file offsets.
895 (make_hdr): Use _data, not start_of_data ().
896 This is the key part of the fix.
897 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
898 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
900 * pre-crt0.c (data_start): Initialize to 1.
901 This ports to compilers that optimize the external declaration
902 'int x = 0;' as if it were 'int x;' to shrink the executable.
904 Improve AIX port (Bug#13650).
905 This doesn't fix the bug, but it makes progress: Emacs builds now.
906 * unexaix.c: Include inttypes.h, stdarg.h.
907 (report_error, report_error_1): Mark as _Noreturn.
908 (report_error): Don't report the wrong errno.
909 (report_error_1): Now varargs. All callers changed.
910 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
911 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
912 (write_ptr): Use %p to print address rather than %lx and a cast
913 to unsigned long. Grow buffer a bit, to be safer.
915 2013-02-13 Eli Zaretskii <eliz@gnu.org>
917 * bidi.c (bidi_resolve_neutral): After finding the next
918 non-neutral character, accept NEUTRAL_ON type as well, because
919 directional control characters, such as LRE and RLE, have their
920 type converted to that by bidi_resolve_weak. This avoids aborts
921 when LRE/RLE follows a run of neutrals.
922 (bidi_move_to_visually_next): Assert that return value of
923 bidi_peek_at_next_level is non-negative. Negative values will
926 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
928 Minor getenv-related fixes.
929 * callproc.c (Fcall_process_region) [!DOS_NT]:
930 Avoid unnecessary duplicate call to getenv.
931 * callproc.c (init_callproc):
932 * dispnew.c (init_display):
933 * sysdep.c (sys_subshell):
934 Omit unnecessary cast of getenv or egetenv.
936 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
938 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
941 2013-02-12 Eli Zaretskii <eliz@gnu.org>
943 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
945 (display_line): Set w->region_showing to the value of
946 it->region_beg_charpos, not to -1. This fixes redisplay
947 optimization when cursor is moved up after M->. (Bug#13623)
949 (try_scrolling): Scroll text up more if point is too close to ZV
950 and inside the scroll margin. This makes sure point is moved
951 outside the scroll margin in these cases.
953 * window.h (struct window): region_showing can no longer be
956 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
958 Tune by using memchr and memrchr.
959 * doc.c (Fsnarf_documentation):
960 * fileio.c (Fsubstitute_in_file_name):
961 * search.c (find_newline, scan_newline):
962 * xdisp.c (pos_visible_p, display_count_lines):
963 Use memchr and memrchr rather than scanning byte-by-byte.

969 (read_key_sequence): Remove unused locals.
971 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>

978 (active_maps): New function.
979 (test_undefined): Also return true for nil bindings.
980 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
981 a single (composed) keymap. Remember `first_event' to choose the right
982 set of active keymaps. Recompute the set of keymaps after receiving
983 the first event. Remove GOBBLE_FIRST_EVENT.
984 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
985 * keyboard.h (read_char): Update declaration.
986 * lread.c (read_filtered_event): Adjust call to read_char.

994 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
996 * marker.c (set_marker_internal): If desired position is passed

1005 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1007 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1008 When text lines are longer than window's screen lines, don't move back
1009 too far. This speeds up some redisplay operations. (Bug#13675)
1011 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1013 * syntax.c (scan_sexps_forward): Fix byte position calculation

1025 (sxhash_float): Return EMACS_UINT, for consistency with the other
1027 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1028 non-static inline function and therefore can't use static vars.
1029 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1030 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1031 with the other hash functions.
1033 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1035 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1036 XXXXXX part of the temporary file pattern is not downcased even
1037 when w32-downcase-file-names is non-nil. (Bug#13661)
1039 * xdisp.c (decode_mode_spec): Remove handling of %t.
1041 * msdos.c (careadlinkatcwd): Remove.
1043 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1045 * lread.c (skip_dyn_bytes): New function (bug#12598).

1086 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1088 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1091 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1096 (ns_last_use_native_fullscreen): New variable.
1097 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1098 (x_set_window_size): Do not take title bar and tool bar into account
1099 if isFullscreen returns YES.
1100 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1101 (check_native_fs): New function.
1102 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.

1118 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1119 (syms_of_nsterm): Add ns-use-native-fullscreen.
1121 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1123 * fileio.c (Qchoose_write_coding_system): Now static.
1125 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1127 * xdisp.c (window_buffer_changed): region_showing can be negative,
1128 which still means region is being displayed.
1129 (redisplay_internal): Resurrect code that forced redisplay of the
1130 whole window when showing region and the mark has changed.
1131 Record the new mark position to allow redisplay optimizations.
1132 (display_line): If it->region_beg_charpos is non-zero, set the
1133 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1135 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1136 not bitfield of 1 bit.
1138 2013-02-03 Daniel Colascione <dancol@dancol.org>
1140 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1141 daemon mode works on cygw32 when Emacs is installed and not just
1144 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1146 Avoid file time stamp bug on MS-Windows (Bug#13149).
1147 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1148 as FAT32 doesn't update time stamps when truncating them.
1149 Also, check that a file time stamp is not a multiple of 100 ns;
1150 this should catch all instances of the problem on MS-Windows,
1151 as its native file system resolution is 100 ns or worse, and
1152 checking for a non-multiple of 100 ns should impose only a small
1153 overhead on systems with ns resolution.
1155 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1157 Avoid encoding file names on MS-Windows when they need to be run
1158 through dostounix_filename.
1159 * w32.c (normalize_filename): Accept an additional argument
1160 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1161 downcase it even if w32-downcase-file-names is non-nil.
1162 (dostounix_filename): Accept an additional argument MULTIBYTE and
1163 pass it to normalize_filename.
1164 (emacs_root_dir): Adjust.
1166 * msdos.h (dostounix_filename): Adjust prototype.
1168 * w32.h (dostounix_filename): Adjust prototype.
1170 * msdos.c (dostounix_filename): Accept an additional argument and
1172 (init_environment): Adjust callers of dostounix_filename.
1174 * fileio.c (Ffile_name_directory, file_name_as_directory)
1175 (directory_file_name, Fexpand_file_name)
1176 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1178 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1180 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1181 variables, as egetenv is case-insensitive for DOS_NT.
1183 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1184 with an encoded file name.
1186 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1187 Adjust calls to dostounix_filename.
1189 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1191 * unexw32.c (unexec): Adjust call to dostounix_filename.
1193 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1195 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1198 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1201 * callproc.c (Fcall_process): Make sure program name in PATH and
1202 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1203 is passed to exec/spawnve, which fails unless the file-name
1206 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1207 even if w32-quote-process-args is nil.
1209 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1211 Fix timestamp bug when write-region appends nothing (Bug#13149).
1212 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1213 the file's time stamp doesn't change if Emacs happens to write nothing
1214 to the file, and on a buggy file system this could cause Emacs to
1215 incorrectly infer that the file system doesn't have the bug.
1216 Avoid this problem by inhibiting the inference in this case.
1218 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1220 * window.h (struct window): Convert base_line_number, base_line_pos
1221 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1231 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1232 (try_scrolling, try_cursor_movement, redisplay_window)
1233 (try_window_reusing_current_matrix, try_window_id, display_line)
1234 (display_mode_lines, decode_mode_spec): Adjust users.
1235 * .gdbinit (pwinx): Do not print sequence_number.
1237 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1239 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1240 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1241 * dired.c: Include <fcntl.h>.
1242 (open_directory): New function, which uses open and fdopendir
1243 rather than opendir. DOS_NT platforms still use opendir, though.

1245 (file_attributes): New function, with most of the old Ffile_attributes.
1246 (directory_files_internal, Ffile_attributes): Use it.
1247 (file_attributes, file_name_completion_stat): First arg is now fd,
1248 not dir name. All uses changed. Use fstatat rather than lstat +
1250 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1251 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1252 (emacs_readlinkat): New function, with much of the old
1253 Ffile_symlink_p, but with an fd argument for speed.
1254 It uses readlinkat rather than careadlinkatcwd, so that it
1255 need not assume the working directory.
1256 (Ffile_symlink_p): Use it.
1257 * filelock.c (current_lock_owner): Use emacs_readlinkat
1258 rather than emacs_readlink.
1259 * lisp.h (emacs_readlinkat): New decl.
1260 (READLINK_BUFSIZE, emacs_readlink): Remove.
1261 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1262 (emacs_norealloc_allocator, emacs_readlink): Remove.
1263 This stuff is moved to fileio.c.
1264 * w32.c (fstatat, readlinkat): New functions.
1265 (careadlinkat): Don't check that fd == AT_FDCWD.
1266 (careadlinkatcwd): Remove; no longer needed.

1278 (sys_close): Zero out the flags for the file descriptor before
1279 closing it. (Bug#13546)
1281 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1282 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1283 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1286 * w32.c (w32_get_long_filename, init_environment, readlink):
1287 Support file names encoded in DBCS codepages.
1288 (readlink): Use the current file-name-coding-system, not the ANSI
1289 codepage, to decode and handle targets of symlinks.
1291 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1293 * w32.c (opendir): Now accepts a 'const char *'.
1295 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1300 (Vredisplay_preemption_period): Likewise.
1301 (update_frame, update_single_window, update_window, update_frame_1):
1302 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not

1307 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1309 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

1312 debugging code. Adjust comment style here and there.
1313 * insdel.c (insert_1): Remove.
1314 * lisp.h (insert_1): Remove prototype.
1315 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1317 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1319 * w32.c (max_filename_mbslen): New function.
1320 (normalize_filename, readdir): Use it to detect locales where ANSI
1321 encoding of file names uses a double-byte character set (DBCS).
1322 If a DBCS encoding is used, advance by characters using
1323 CharNextExA, instead of incrementing a 'char *' pointer.
1324 Use _mbslwr instead of _strlwr. (Bug#13515)
1326 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1327 request of memory reservation to 1.7GB. (Bug#13065)

1337 Avoid redundant calls to strlen.
1339 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1341 Drop async_visible and async_iconified fields of struct frame.

1343 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1344 * frame.h (struct frame): Remove async_visible and async_iconified
1345 members, convert garbaged to unsigned bitfield. Adjust comments.

1363 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1365 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1367 * xdisp.c (message2, message2_nolog): Remove functions.
1368 (message3, message3_nolog): Extract nbytes and multibyteness directly
1369 from the string. Change all callers.
1370 (message3_nolog): Don't set message_enable_multibyte since set_message
1371 will reset it anyway.
1372 (message1, message1_nolog): Use message3.
1373 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1374 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1375 (set_message): Drop all but the second arg, which has to be a string.
1376 (set_message_1): Simplify now that we know that a1 is NULL and the
1377 second arg is a string.

1389 * editfns.c (message_text, message_length): Remove vars.
1390 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1391 * fileio.c (auto_save_error): Use message3 instead of message2.

1409 * window.c (adjust_window_count): Clear window_end_valid.
1410 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1411 (Fwindow_line_height, set_window_buffer, Frecenter)
1412 (Fsplit_window_internal, Fdelete_other_windows_internal)
1413 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1414 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1415 * xdisp.c (check_window_end, reconsider_clip_changes)
1416 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1417 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1418 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1420 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1422 * xdisp.c (mark_window_display_accurate): Simplify the loop
1423 assuming that the only one of vchild, hchild or buffer window
1424 slots is non-nil. Call mark_window_display_accurate_1 for
1425 the leaf windows only.
1426 (mark_window_display_accurate_1): Always assume leaf window.
1429 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1431 * emacs.c (Qkill_emacs_hook): Now static.
1433 * fileio.c (Finsert_file_contents): Simplify.
1434 Remove unnecessary assignments and tests.
1436 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1438 * w32.c (acl_set_file): Don't test for errors unless
1439 set_file_security returns FALSE. Avoids spurious errors when
1442 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1444 * fileio.c (Finsert_file_contents): Revert code introduced at
1445 2013-01-18 in favor of the simpler and generally better fix.
1446 Save stack space by removing 'buffer' and reusing 'read_buf'
1449 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1451 * lisp.h (eabs): Define unconditionally (Bug#13419).
1452 The old "#if !defined (eabs)" was an unnecessary revenant of back
1453 when this macro was called "abs". Document 'eabs' better.
1455 2013-01-19 Glenn Morris <rgm@gnu.org>
1457 * fns.c (Frandom): Doc fix.
1459 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1461 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1462 segfault when there are lots of overlays.
1464 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1465 when there are lots of overlays.
1466 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1467 for the details and a way to reproduce.
1469 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1471 * fileio.c: Use O_APPEND to append.
1472 This corresponds better to the natural interpretation of "append",
1473 and avoids the need to open the output file twice, or to invoke
1474 lseek when APPEND is neither nil nor a number.
1475 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1476 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1477 file possibly twice, and lseeking to its end; this avoids the
1478 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1479 at the same time: the combination is never needed and apparently
1480 it doesn't work with DOS_NT.
1482 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1483 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1485 Allow floating-point file offsets.
1486 Problem reported by Vitalie Spinu in
1487 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1488 * fileio.c (emacs_lseek): Remove.
1489 (file_offset): New function.
1490 (Finsert_file_contents, Fwrite_region): Use it.
1492 2013-01-19 Chong Yidong <cyd@gnu.org>
1494 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1495 aborting on Fsignal (Bug#13289).
1497 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1499 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1500 set_file_security as failure due to insufficient privileges.
1501 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1502 (fstat): Return owner and group like 'stat' and 'lstat' do.
1504 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1506 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1507 The bug was observed on Ubuntu operating inside a virtual machine,
1508 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1509 The workaround introduces a race condition on non-buggy hosts,
1510 but it's an unlikely race and anyway there's a nearly identical
1511 nearby race that can't be fixed.
1512 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1514 (Fwrite_region): Test for file system time stamp bug.
1515 (init_fileio): New function.
1516 * lisp.h (init_fileio): Declare it.
1517 * emacs.c (main): Call it.
1519 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1520 and make it more consistent with other stat-failure diagnostics.
1522 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1524 Fix crash when inserting data from non-regular files.
1525 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1526 for the error description produced by valgrind.
1527 * fileio.c (read_non_regular): Rename to read_contents.
1528 Free Lisp_Save_Value object used to pass parameters.
1529 (read_non_regular_quit): Rename to read_contents_quit.
1530 (Finsert_file_contents): Redesign internal file reading loop to adjust
1531 gap and end positions after each read and so help make_gap to work
1532 properly. Do not signal an I/O error too early and so do not leave
1533 not yet decoded characters in a buffer, which was the reason of
1534 redisplay crash. Use list2 to build return value. Adjust comments.
1536 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1538 Close a race when statting and reading files (Bug#13149).
1539 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1540 This avoids a race if the file is renamed between stat and open.
1541 This race is not the problem originally noted in Bug#13149;
1542 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1544 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1551 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1552 * alloc.c (format_save_value): Rename to make_save_value.
1553 (make_save_pointer): New function.
1554 (record_xmalloc): Use make_save_pointer.
1555 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1556 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1557 Change users of make_save_value to make_save_pointer.
1558 Likewise for format_save_value and make_save_value.

1571 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1573 * keymap.c (map_keymap_internal): Use format_save_value.
1574 (map_keymap_char_table_item): Adjust accordingly.
1575 * fileio.c (non_regular_fd, non_regular_inserted)
1576 (non_regular_nbytes): Remove.
1577 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1578 Use format_save_value to pass parameters to read_non_regular.
1579 (read_non_regular): Use XSAVE_ macros to extract parameters.
1581 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1583 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1585 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1587 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1588 extraction from any Lisp_Save_Value slot. Add type checking.
1589 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1590 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1591 * xselect.c: All users changed.
1593 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1603 * editfns.c (save_excursion_save): Use format_save_value.
1604 (save_excursion_restore): Use XSAVE_OBJECT.
1606 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1608 Avoid needless casts with XSAVE_POINTER.
1609 * alloc.c (mark_object) [GC_MARK_STACK]:
1610 * dired.c (directory_files_internal_unwind):
1611 * fileio.c (do_auto_save_unwind):
1612 * gtkutil.c (pop_down_dialog):
1613 * keymap.c (map_keymap_char_table_item):
1614 * lread.c (load_unwind):
1615 * nsmenu.m (pop_down_menu):
1616 * print.c (print_object) [GC_MARK_STACK]:
1617 * xfns.c (clean_up_file_dialog):
1618 * xmenu.c (cleanup_widget_value_tree):
1619 Omit casts between XSAVE_POINTER and a pointer type.
1621 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1623 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1624 * eval.c (eval_sub): Protect `form' from being GCed before its
1625 car and cdr becomes protected with the backtrace entry.
1627 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1629 Make Lisp_Save_Value more versatile storage for up to four objects.

1639 (free_save_value): Likewise.
1640 (mark_object): Likewise.
1641 * editfns.c (save_excursion_save): Pack everything within
1642 Lisp_Save_Value and so avoid xmalloc.
1643 (save_excursion_restore): Adjust to match new layout. Use free_misc
1644 because we do not allocate extra memory any more. Add eassert.
1645 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1646 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1656 Bug#11484 with LCD smoothing on.
1658 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1660 Fix SIGDANGER handlers, for AIX (Bug#13408).
1661 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1662 Move handlers here from emacs.c; they were out of place.
1664 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1666 * xterm.c (syms_of_xterm): Adjust documentation for

1687 (nsfont_open): Move block_input earlier. Add unblock_input before early
1689 (nsfont_draw): Add block/unblock_input calls.
1691 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
1693 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
1694 for old_charpos and old_bytepos.

1698 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
1699 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
1700 Clear tzvalbuf_in_environ if this workaround is in effect.
1701 Problem and fix reported by Kazuhiro Ito.
1703 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

1712 string cross-reference(s).
1714 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1716 Avoid unnecessary byte position calculation for the gap movement.
1717 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1718 anyway, all of them should use move_gap_both instead.
1719 * lisp.h (move_gap): Remove prototype.
1720 * insdel.c (move_gap): Remove.
1721 (move_gap_both): Add eassert.

1728 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1730 * term.c (init_tty): Use them instead of rolling our own code.
1731 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1732 switches from 'signal' to 'pthread_sigmask', which is safer in
1733 multithreaded applications.
1734 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1735 which has already arranged for that.
1736 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

1746 Omit buffer_slot_type_mismatch and use generic predicates to enforce
1747 the type of per-buffer values where appropriate.
1748 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
1749 predicate, which is how it's really used now. Adjust comment.
1750 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1751 * buffer.c (buffer_slot_type_mismatch): Remove.
1752 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

1757 right-fringe-width, scroll-bar-width and buffer-display-count.
1758 Use Qstringp for default-directory, buffer-file-name,
1759 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1760 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1762 * data.c (store_symval_forwarding): Adjust to call the predicate.
1764 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
1766 * w32.c (get_name_and_id, acl_set_file):

1778 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1779 (make_gap_1): New function to adjust the gap of any buffer.
1780 * coding.c (coding_alloc_by_making_gap): Use it.
1781 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1782 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1784 2013-01-08 Juri Linkov <juri@jurta.org>
1786 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
1787 of (supports :underline (:style wave)). (Bug#13000)

1805 trailing dash is properly added.
1807 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1809 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1810 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1811 digits for buffer positions, before misalignment starts.
1812 Display "0" for integer "object" field.
1813 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1814 Display the newline glyph more unambiguously.

1824 * w32term.c (x_draw_glyph_string):
1825 * xterm.c (x_draw_glyph_string): Don't use previous underline
1826 thickness and position if previous underline type is underwave.

1868 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1869 Show all on TOOLBAR_TOP_WIDGET.
1870 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1871 by TOOLBAR_TOP_WIDGET.
1872 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1873 Check toolbar_is_packed.
1874 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1875 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1876 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1878 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1879 (xg_update_menubar): Update title only if
1880 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1881 (xg_update_submenu): Skip tearoff only if
1882 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1883 (xg_initialize): Initialize xg_detached_menus only if
1884 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1886 * xterm.h (struct x_output): Surround handlebox_widget with
1887 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1888 toolbar_in_hbox is bool.
1890 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1892 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1893 (LIBS_GNUSTEP): Define.
1894 (LIBES): Add $(LIBS_GNUSTEP).
1895 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1897 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1899 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1900 continuation glyph on a TTY with an indication of an empty line.
1903 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1905 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1906 file's SELinux context or ACLs successfully set, nil otherwise.
1908 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1910 * w32proc.c (reader_thread): Avoid passing NULL handles to
1911 SetEvent and WaitForSingleObject.
1913 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1915 Port EXTERNALLY_VISIBLE to Clang 3.2.
1916 * conf_post.h (__has_attribute): New macro.
1917 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1919 2012-12-27 Glenn Morris <rgm@gnu.org>
1921 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1922 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1924 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1926 * fileio.c (file_name_as_directory, directory_file_name):
1927 Accept an additional argument MULTIBYTE to indicate whether the input C
1928 came from a multibyte or a unibyte Lisp string; all callers
1929 adjusted. Don't assume the input string is always multibyte.
1931 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1932 don't ENCODE_FILE them, and return a unibyte string if the input
1934 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1935 don't assume the input strings will always be multibyte. If the
1936 input strings are multibyte, decode strings obtained from C
1939 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1941 * lisp.h (toplevel): Add two notices to the comment about
1942 defining a new Lisp data type.

1946 * alloc.c (valid_lisp_object_p): Adjust comment.
1948 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1950 * keyboard.c (record_asynch_buffer_change): Initialize an event
1951 only if it's really needed.
1952 * frame.h (enum output_method): Remove output_mac member since
1953 it's a leftover from the deleted code.
1954 * frame.c (Fframep): Adjust user here ...
1955 * terminal.c (Fterminal_live_p): ... and here.
1956 * coding.c (Qmac): Now here because it's only used to denote
1957 end-of-line encoding type.
1958 (syms_of_coding): DEFSYM it.
1959 * frame.h (Qmac): Remove duplicated declaration.
1961 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1963 * window.c (select_window_1): Now static, since it's used only here.
1965 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1967 * window.c (window_body_cols): Subtract display margins from the
1968 window body width on TTYs as well. See
1969 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1970 for the original report.
1972 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1974 * xdisp.c (redisplay_window): Remove inner local variable
1975 because the outer shadowed one has the same meaning.
1976 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1978 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1979 (xg_create_tool_bar): Adjust users.
1981 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1983 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1984 * buffer.c (Fget_buffer_create): Use it to set compact field of
1985 struct buffer_text to avoid accessing an uninitialized value
1986 when compact_buffer is called for the first time.
1987 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1988 (Fset_buffer_modified_p): Use buffer_window_count to check
1989 whether the buffer is displayed in some window.
1990 * xdisp.c (message_dolog): Likewise.
1992 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1994 * w32.c (acl_set_file): If setting the file security descriptor
1995 fails, and the new DACL is identical to the existing one, silently
1996 return success. This fixes problems for users backing up their
1997 own files without having the necessary privileges for setting
1998 security descriptors.
2000 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2002 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2003 after WaitForSingleObject returns normally. This expedites reader
2004 thread shutdown when delete_child triggers it.
2005 (reap_subprocess): More accurate commentary for why we call
2006 delete_child only when cp->fd is negative.
2008 * w32.c (sys_close): Do not call delete_child on a subprocess
2009 whose handle is not yet closed. Instead, set its file descriptor
2010 to a negative value, so that reap_subprocess will call
2011 delete_child on that subprocess when its SIGCHLD arrives.
2012 This avoids closing handles used for communications between sys_select
2013 and reader_thread, which doesn't give sys_select a chance to
2014 notice that the process exited and invoke the SIGCHLD handler for
2017 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2019 * nsfns.m (Fns_do_applescript): Run event loop until script has
2020 been executed (Bug#12969).
2021 (ns_run_ascript): Chech as_script for nil, set to nil after
2024 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2026 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2028 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2030 * w32term.c (w32fullscreen_hook): New function.
2031 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2033 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2035 * fileio.c (Finsert_file_contents): Doc fix.
2037 * w32proc.c (new_child, delete_child, find_child_pid): For a
2038 subprocess, consider its slot being in use as long as its process
2039 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2040 slot when a new process is started immediately after killing
2041 another one, without waiting enough time for the first process to
2042 be reaped and resources allocated for it be orderly freed.
2044 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2046 2012-12-21 Chong Yidong <cyd@gnu.org>
2048 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2050 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2052 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2054 * w32.c (get_name_and_id): Always pass NULL as the first argument
2055 of lookup_account_sid. Avoids crashes with UNC file names that
2056 refer to DFS domains, not to specific machine names. (Bug#12621)
2057 Remove now unused argument FNAME; all callers changed.
2058 (get_file_owner_and_group): Remove now unused argument FNAME; all
2061 2012-12-21 Chong Yidong <cyd@gnu.org>
2063 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2064 error for invalid chars, don't check for a nil return value.
2066 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2068 Avoid calls to CHAR_TO_BYTE if byte position is known.
2069 * editfns.c (make_buffer_string_both): Use move_gap_both.
2070 (Fbuffer_string): Use make_buffer_string_both.
2071 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2073 (buf_bytepos_to_charpos): Likewise.
2074 (charpos_to_bytepos): Remove.
2075 * fileio.c (Finsert_file_contents): Use move_gap_both.
2076 * search.c (Freplace_match): Likewise.
2077 * process.c (process_send_region): Likewise. Use convenient
2078 names for byte positions.
2079 * lisp.h (charpos_to_bytepos): Remove prototype.
2080 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2081 * insdel.c (move_gap): Likewise.
2083 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2085 * xdisp.c (redisplay_internal): Remove now-unused local.
2087 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2089 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2090 (redisplay_internal): Don't bother selecting the frame to get the
2091 proper value of frame-local variables (bug#13225).
2093 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2095 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2096 Rename 4th argument since it may be buffer or string. Adjust comment.
2097 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2099 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2101 * coding.c (Fdetect_coding_region): Do not check start and end with
2102 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2103 (code_convert_region): Likewise.
2105 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2107 * w32.c (acl_get_file, acl_set_file): Run the file name through
2108 map_w32_filename, and resolve any symlinks in the file name, like
2110 (acl_set_file): Call revert_to_self, if any privileges were
2113 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2115 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2116 ($(BLD)/w32.$(O)): Update dependencies.
2118 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2120 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2121 propagate redisplay's scrolling (if any) to the right window.
2122 (redisplay_internal): Use ensure_selected_frame.
2123 (display_mode_lines): Complete last fix.
2124 * window.c (select_window_1): New func, extracted from select_window.
2125 (select_window): Use it.
2126 * window.h (select_window_1): Declare.
2128 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2130 Emulate Posix ACL APIs on MS-Windows.
2131 * w32.c: Include sddl.h and sys/acl.h.
2132 (SDDL_REVISION_1): Define if not already defined.
2133 (g_b_init_get_security_descriptor_dacl)
2134 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2135 (g_b_init_is_valid_security_descriptor)

2148 (acl_free, acl_get_file, acl_set_file): New functions.
2150 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2152 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2154 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2155 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2156 for some of that bug's symptoms can now cause Emacs to abort.
2157 Remove the workaround.
2158 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2159 The bug that caused SIGCHLD to get lost has been fixed, and the
2160 workaround for it can now cause Emacs to abort.
2162 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2164 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2165 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2166 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2168 2012-12-16 Romain Francoise <romain@orebokech.com>
2170 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2171 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2172 and copy ACL entries of file in addition to SELinux context if set.
2173 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2175 * Makefile.in (LIBACL_LIBS): New macro.

2190 * w32proc.c (new_child): Initialize input_file and
2191 pending_deletion members of the child.
2192 (delete_child): Delete the child's temporary input file, if any,
2193 that is pending deletion.
2194 (register_child): First argument is now pid_t.
2195 (record_infile, record_pending_deletion): New functions.
2196 (reap_subprocess): Fix a typo in DebPrint string.
2197 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2199 * fileio.c (internal_delete_file): Return an int again: non-zero
2200 if delete-file succeeds, zero otherwise.
2202 * lisp.h (internal_delete_file): Adjust prototype.
2204 * callproc.c (Fcall_process): Don't overwrite infile with result
2206 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2207 asynchronous subprocess, record the name of the input file name,
2209 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2210 delete the file, record it as pending deletion when the subprocess
2213 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2215 * editfns.c [HAVE_PWD_H]: Include grp.h.
2217 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

2221 Fix permissions bugs with setgid directories etc. (Bug#13125)
2222 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2223 to mark it as a placeholder. The old value was often wrong.
2224 The only user of this attribute has been changed to use
2225 file-ownership-preserved-p instead, with its new group arg.
2226 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2228 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2233 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2235 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2236 try to get accurate owner and group information from NT file
2237 security APIs. This is to make most callers of 'stat' and
2238 'lstat', which don't need that information, much faster.
2240 * dired.c (Ffile_attributes) [WINDOWSNT]:
2241 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2242 owner and group information from 'lstat'.
2244 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2246 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2247 as that confuses set-auto-coding, so insist on the head-read
2248 returning the full 1024 bytes. Let lseek compute the tail offset;
2249 less work for us. Do not ignore I/O errors when reading the tail.
2251 * xdisp.c: Minor style fixes.
2252 (init_iterator): Hoist assignment out of if-expression.
2253 (markpos_of_region): Callers now test for sign, not for -1.
2255 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2257 Minor redisplay optimization when the region length is zero.
2258 * xdisp.c (markpos_of_region): New function.
2259 (init_iterator): Do not highlight the region of zero length.
2260 (redisplay_window): Check whether the region is of non-zero length.
2261 (try_cursor_movement): Allow if the region length is zero.
2262 (try_window_reusing_current_matrix, try_window_id): Likewise.
2264 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2266 * search.c (search_buffer): Check the inverse translations of each
2267 character in pattern when the buffer being searched is unibyte.
2270 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2272 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2273 files, fixing a regression from 24.2.
2274 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2276 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2278 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2279 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2280 Remove unnecessary S_ISLNK test, as (contra the comments) this
2281 function can't copy symlinks. Improve quality of error message
2282 when attempting to copy files that are neither regular files nor

2289 * window.c (Frecenter):
2290 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2291 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2293 2012-12-12 Daniel Colascione <dancol@dancol.org>
2295 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2296 the dumped Emacs is not a sparse file, greatly improving Cygwin
2297 "make bootstrap" performance.
2299 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2301 * inotify.c (inotify_callback): Generate an Emacs event for every
2302 incoming inotify event.
2304 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2306 * xdisp.c (handle_face_prop): Fix logic of computing
2307 it->start_of_box_run_p.
2308 (append_space_for_newline): If the glyph row is R2L, reset the
2309 iterator's end_of_box_run_p flag before prepending the space glyph.
2310 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2311 iterator's start_of_box_run_p flag before prepending the stretch.
2312 (append_glyph, produce_image_glyph, append_composite_glyph)
2313 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2314 left_box_line_p and right_box_line_p flags of the glyph for R2L
2315 glyph rows. (Bug#13011)
2317 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2319 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2320 if changed buffer is not shown in a window.
2321 * insdel.c (prepare_to_modify_buffer): Likewise.
2322 * window.c (replace_buffer_in_windows_safely): Do nothing
2323 if buffer is not shown in a window.

2329 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2330 encoded_file_name, which is what it is.
2332 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2334 Consistently use marker_position and marker_byte_position.
2335 * fringe.c (Ffringe_bitmaps_at_pos):

2509 * w32.c (unsetenv): Return 0 if the input string is too long.
2511 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2513 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

2515 * dbusbind.c (Fdbus_init_bus):
2517 * xterm.c (x_term_init):

2528 no longer needed here.
2529 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2530 Move to inside set_time_zone_rule; they don't need file scope any more.
2531 (set_time_zone_rule): Maintain the TZ=value string separately.
2532 (syms_of_editfns): Don't initialize initial_tz;
2533 init_editfns now does it.
2534 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2535 * lisp.h (xputenv): New decl.
2537 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2539 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2541 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2543 * w32.c (unsetenv, sys_putenv): New functions.
2545 2012-12-08 Chong Yidong <cyd@gnu.org>

2548 informative (Bug#12992).
2550 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2552 Simplify get_lim_data.
2553 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2554 Remove USG and vlimit methods; no longer used these days.
2555 Add #error catchall just in case.
2557 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2558 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2559 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2560 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2561 (deleted_pid_list, Fdelete_process, create_process)
2562 (record_child_status_change, handle_child_signal, deliver_child_signal)

2566 (abbr_to_signal): New static function.
2567 (Fsignal_process): Use it to convert signal names to ints.

2578 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2580 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2581 This will cause a production Emacs to dump core instead of
2584 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2586 * frame.c (make_frame): Do not set window's buffer to t.
2587 * window.c (Fsplit_window_internal): Likewise. Previously it was
2588 used to indicate that the window is being set up. Now we use
2589 set_window_buffer for all new windows, so the condition in ...
2590 (Fset_window_buffer): ... is always true and can be removed.
2592 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2594 Convenient macro to check whether the buffer is hidden.
2595 * buffer.h (BUFFER_HIDDEN_P): New macro.
2596 * frame.c (make_frame): Use it. Adjust comment.
2597 * buffer.c (candidate_buffer): New function.
2598 (Fother_buffer, other_buffer_safely): Use it.
2600 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2602 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2603 if the child process is still running. Instead, exit the wait
2604 loop and return zero. (Bug#13086)
2606 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2608 * frame.h (x_char_width, x_char_height): Remove prototypes.

2622 * callproc.c, process.h (record_kill_process):
2623 New function, containing part of the old call_process_kill.
2624 (call_process_kill): Use it.
2625 This does not change call_process_kill's behavior.
2626 * process.c (Fdelete_process): Use record_kill_process to fix a
2627 race condition that could cause Emacs to lose track of a child.
2629 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2631 Avoid code duplication between prev_frame and next_frame.
2632 * frame.c (candidate_frame): New function. Add comment.
2633 (prev_frame, next_frame): Use it. Adjust comment.
2635 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2637 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2638 fails, signal an error instead of continuing with an empty
2640 Encode expanded temp file pattern before passing it to mkstemp or
2643 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2644 Encode the file name before passing it to dostounix_filename, in
2645 case it will downcase it (under w32-downcase-file-names).
2648 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2650 Minor call-process cleanups.
2651 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2652 at the same time as other platforms, to simplify analysis.
2653 No need for fd0_volatile since we have synch_process_fd.
2654 Avoid needless emacs_close; arg is always negative.
2656 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2658 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2661 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2663 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2664 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2665 and mouse_face_hidden members to a bitfields.

2667 (FRAME_SPACE_WIDTH): Remove.
2668 * nsterm.m, w32term.c, xterm.c: Adjust users.
2669 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2670 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2671 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2672 members to a bitfields.
2674 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2676 Don't let call-process be a zombie factory (Bug#12980).
2677 Fixing this bug required some cleanup of the signal-handling code.
2678 As a side effect, this change also fixes a longstanding rare race
2679 condition whereby Emacs could mistakenly kill unrelated processes,
2680 and it fixes a bug where a second C-g does not kill a recalcitrant
2681 synchronous process in GNU/Linux and similar platforms.
2682 The patch should also fix the last vestiges of Bug#9488,
2683 a bug which has mostly been fixed on the trunk by other changes.
2684 * callproc.c, process.h (synch_process_alive, synch_process_death)
2685 (synch_process_termsig, sync_process_retcode):
2686 Remove. All uses removed, to simplify analysis and so that
2687 less consing is done inside critical sections.
2688 * callproc.c (call_process_exited): Remove. All uses replaced
2689 with !synch_process_pid.
2690 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2691 These take the role of what used to be in unwind-protect arg.
2693 (block_child_signal, unblock_child_signal):
2694 New functions, to avoid races that could kill innocent-victim processes.
2695 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2696 (call_process_kill): Record killed processes as deleted, so that
2697 zombies do not clutter up the system. Do this inside a critical
2698 section, to avoid a race that would allow the clutter.
2699 (call_process_cleanup): Fix code so that the second C-g works again
2700 on common platforms such as GNU/Linux.
2701 (Fcall_process): Create the child process in a critical section,
2702 to fix a race condition. If creating an asynchronous process,
2703 record it as deleted so that zombies do not clutter up the system.
2704 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2705 light of these changes. Omit unnecessary call to emacs_close
2706 before failure, as the unwind-protect code does that.
2707 * callproc.c (call_process_cleanup):
2708 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2709 * process.c (record_deleted_pid): New function, containing
2710 code refactored out of Fdelete_process.
2711 (Fdelete_process): Use it.
2712 (process_status_retrieved): Remove. All callers changed to use
2713 child_status_change.
2714 (record_child_status_change): Remove, folding its contents into ...
2715 (handle_child_signal): ... this signal handler. Now, this
2716 function is purely a handler for SIGCHLD, and is not called after
2717 a synchronous waitpid returns; the synchronous code is moved to
2718 wait_for_termination. There is no need to worry about reaping
2719 more than one child now.
2720 * sysdep.c (get_child_status, child_status_changed): New functions.
2721 (wait_for_termination): Now takes int * status and bool
2722 interruptible arguments, too. Do not record child status change;
2723 that's now the caller's responsibility. All callers changed.
2724 Reimplement in terms of get_child_status.
2725 (wait_for_termination_1, interruptible_wait_for_termination):
2726 Remove. All callers changed to use wait_for_termination.
2727 * syswait.h: Include <stdbool.h>, for bool.
2728 (record_child_status_change, interruptible_wait_for_termination):
2730 (record_deleted_pid, child_status_changed): New decls.
2731 (wait_for_termination): Adjust to API changes noted above.
2733 * bytecode.c, lisp.h (Qbytecode): Remove.
2734 No longer needed after 2012-11-20 interactive-p changes.
2736 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2738 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2739 the scroll margin, move point outside the margin. (Bug#13055)
2741 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2743 * gtkutil.c (my_log_handler): New function.
2744 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2746 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2748 * lisp.h (modify_region): Rename to...
2749 (modify_region_1): ...new prototype.
2750 * textprop.c (modify_region): Now static. Adjust users.
2751 * insdel.c (modify_region): Rename to...
2752 (modify_region_1): ...new function to work with current buffer.
2753 Adjust comment and users. Use true and false for booleans.
2755 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2757 * alloc.c (free_save_value): New function.
2758 (safe_alloca_unwind): Use it.
2759 * lisp.h (free_save_value): New prototype.
2760 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2762 (save_excursion_restore): Adjust to match saved data structure.
2763 Use free_save_value to offload some work from GC. Drop obsolete
2766 2012-12-03 Chong Yidong <cyd@gnu.org>
2768 * fileio.c (Vauto_save_list_file_name): Doc fix.
2770 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2772 * w32fns.c: Remove prototype of atof.
2773 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2775 (file_dialog_callback): Make it UINT_PTR.
2777 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2780 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2781 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2784 2012-12-03 Glenn Morris <rgm@gnu.org>
2786 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2788 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2790 Fix xpalloc confusion after memory is exhausted.
2791 * alloc.c (xpalloc): Comment fix.
2792 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2793 and signals an error, do not clear charset_table_size, as
2794 charset_table is still valid.
2795 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2797 Use execve to avoid need to munge environ (Bug#13054).
2798 * callproc.c (Fcall_process):
2799 * process.c (create_process):
2800 Don't save and restore environ; no longer needed.
2801 * callproc.c (child_setup):
2802 Use execve, not execvp, to preserve environ.
2804 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2806 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

2810 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2811 display for sliced images (Bug#10500).
2813 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2815 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2817 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2818 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2820 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2822 * xdisp.c (window_outdated): Remove eassert since it hits
2823 some suspicious corner cases (see Bug#13007 and Bug#13012).
2824 (mode_line_update_needed): New function.
2825 (redisplay_internal, redisplay_window): Use it.
2826 (ensure_selected_frame): New function.
2827 (redisplay_internal, unwind_redisplay): Use it.
2828 (redisplay_internal): Move comment about buffer_shared...
2829 (buffer_shared_and_changed): ...near to its real use.
2831 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2833 * callproc.c (Fcall_process): Don't misreport vfork failure.
2835 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2837 * callproc.c (Fcall_process): Fix vfork portability problems.
2838 Do not assume that fd[0], count, filefd, and save_environ survive
2839 vfork. Fix bug whereby wrong errno value could be reported for
2840 pipe failure. Some minor cleanups, too, as follows. Move buf and
2841 bufsize to the context where they're needed. Change new_argv to
2842 be of type char **, as this is more convenient and avoids casts.
2843 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2844 Now local constants, not macros.
2846 2012-11-18 Kenichi Handa <handa@gnu.org>
2848 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2849 for the variable "f".
2851 2012-11-13 Kenichi Handa <handa@gnu.org>
2853 * font.c (font_unparse_xlfd): Exclude special characters from the
2854 generating XLFD name.
2856 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2858 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2859 * dired.c (stat_uname, stat_gname):
2860 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2862 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2866 * fileio.c (Fcopy_file): Assume EISDIR is defined.
2867 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
2868 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
2869 * lread.c (readbyte_from_file): Assume EINTR is defined.
2870 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2871 Assume EIO and EAGAIN are defined.
2872 * unexcoff.c (write_segment): Assume EFAULT is defined.
2874 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2876 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2879 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2880 highlighting on the frame was cleared. Prevents assertion
2881 violations when repeatedly clicking on the "Top" link of the
2882 "bread-crumbs" in Info buffers.
2884 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2886 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2888 2012-11-24 Ken Brown <kbrown@cornell.edu>
2890 * keyboard.c (HAVE_MOUSE):
2891 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2892 were always defined.
2894 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2896 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2897 between bpos_covered and bpos_max. This fixes cursor display when
2898 several display strings follow each other.
2900 * .gdbinit (pgx): If the glyph's object is a string, display the
2901 pointer to string data, rather than the value of the string object
2902 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2904 * indent.c (Fvertical_motion): If the starting position is covered
2905 by a display string, return to one position before that, to avoid
2906 overshooting it inside move_it_to. (Bug#12930)
2908 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2910 * frame.h (struct frame): Remove display_preempted member
2911 since all users are dead long ago.
2912 * nsterm.h (struct x_output): Use the only dummy member.
2913 * w32menu.c (pending_menu_activation): Remove since not
2915 (set_frame_menubar): Adjust user.
2916 * w32term.h (struct x_output): Drop outdated #if 0 code.
2917 (struct w32_output): Use bitfields for explicit_parent,
2918 asked_for_visible and menubar_active members.
2919 Drop unused pending_menu_activation member.
2920 * xterm.h (struct x_output): Drop outdated #if 0 code.
2921 Use bitfields for explicit_parent, asked_for_visible,
2922 has_been_visible and net_wm_state_hidden_seen members.
2924 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2926 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2927 of a literal "/". (Bug#12955)
2928 (gl-stamp): Invoke fc.exe directly, not through cmd.
2930 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2932 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2933 * dired.c: Assume HAVE_DIRENT_H.
2934 (NAMLEN): Remove, replacing with ...
2935 (dirent_namelen): New function. All uses changed. Use the GNU macro
2936 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2937 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2938 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2939 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2941 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2942 * ndir.h: Rename to ../nt/inc/dirent.h.
2943 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2944 Do not include <dirent.h>; no longer needed.
2945 * w32.c: Include <dirent.h> rather than "ndir.h".
2947 2012-11-23 Chong Yidong <cyd@gnu.org>
2949 * xftfont.c (xftfont_open): Remove duplicate assignment.
2951 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2953 * alloc.c (Fgarbage_collect): Unblock input after clearing
2954 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2955 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2956 * msdos.c (IT_frame_up_to_date): Use it here...
2957 * w32term.c (w32_frame_up_to_date): ...here...
2958 * xterm.c (XTframe_up_to_date): ...and here...
2959 * nsterm.m (ns_frame_up_to_date): ...but not here.
2960 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2962 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2963 Do not check whether GC is in progress.
2965 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2967 * xdisp.c (window_buffer_changed): New function.
2968 (update_menu_bar, update_tool_bar): Use it to
2969 simplify large 'if' statements.
2970 (redisplay_internal): Generalize commonly used
2971 'tail' and 'frame' local variables.
2973 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2975 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2976 with Windows system header.
2978 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2980 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2981 * alloc.c: Assume unistd.h exists.
2982 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2983 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2984 (getwd) [USG]: Remove; no longer needed.
2985 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2986 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2987 * w32.h (getcwd): Remove decl.
2989 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2991 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2992 Make it set selected_window as well.
2993 (update_tool_bar): Use it.
2995 2012-11-21 Ken Brown <kbrown@cornell.edu>
2997 * emacs.c (main): Set the G_SLICE environment variable for all
2998 Cygwin builds, not just GTK builds. See
2999 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3001 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3003 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3004 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3005 Define for the MSVC compiler.
3007 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3009 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3010 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3011 dostounix_filename. Prevents crashes down the road, because
3012 dostounix_filename assumes it gets a unibyte string.
3013 Reported by Michel de Ruiter <michel@sentient.nl>, see
3014 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3016 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3020 * lread.c (init_obarray): Set `function' fields to Qnil.
3021 * eval.c (Fcommandp): Ignore Qunbound.
3022 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3023 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3024 Test NILP rather than Qunbound.
3025 (Ffmakunbound): Set to Qnil.
3026 (Fsymbol_function): Never signal an error.
3027 (Finteractive_form): Ignore Qunbound.
3029 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3031 * eval.c (interactive_p): Remove no-longer-used decl.
3033 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3035 * xdisp.c (buffer_shared): Adjust comment.
3036 (buffer_shared_and_changed): New function.
3037 (prepare_menu_bars, redisplay_internal): Use it to
3038 decide whether all windows or frames should be updated.
3039 (window_outdated): New function.
3040 (text_outside_line_unchanged_p, redisplay_window): Use it.
3041 (redisplay_internal): Likewise. Fix indentation.
3043 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3045 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3046 (syms_of_eval): Remove corresponding defsubr.
3047 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3049 2012-11-19 Daniel Colascione <dancol@dancol.org>
3051 * w32fns.c (Fx_file_dialog):
3052 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3053 cygwin_convert_file_name*.
3055 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3056 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3058 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3060 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3062 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3064 * w32select.c: Include w32common.h before w32term.h, so that
3065 windows.h gets included before w32term.h uses some of its
3066 features, see below.
3068 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3070 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3072 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3074 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3076 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3077 (ns_select): Return at once if events are held (Bug#12834).
3079 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3081 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3082 Needed following 2012-10-20 change. (Bug#12902)
3084 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3086 * w32proc.c (waitpid): Remove unused label get_result.
3088 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3090 * makefile.w32-in (SYSWAIT_H): New macro.
3091 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3092 ($(BLD)/sysdep.$(O)): Update dependencies.
3094 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3096 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3097 * callproc.c (relocate_fd): Assume F_DUPFD.
3098 * emacs.c, term.c (O_RDWR): Remove.
3099 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3100 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3101 * nsterm.m: Assume <fcntl.h> exists.
3102 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3103 (create_pty, Fmake_network_process, server_accept_connection)
3104 (wait_reading_process_output, init_process_emacs):
3106 (wait_reading_process_output): Put in a special case for WINDOWSNT
3107 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3108 It's not clear this is needed, but it's a more-conservative change.
3109 (create_process): Assume FD_CLOEXEC.
3110 (create_process, create_pty): Assume O_NOCTTY.
3111 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3112 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3113 Omit if not DOS_NT, since F_GETFL is not defined there.
3114 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3115 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3117 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3118 lack it, since gnulib guarantees this.
3119 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3121 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3123 * w32.c (faccessat): Pretend that directories have the execute bit
3124 set. Emacs expects that, e.g., in files.el:cd-absolute.
3126 * w32proc.c (create_child): Don't clip the PID of the child
3127 process to fit into an Emacs integer, as this is no longer a
3129 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3130 reaping only the process specified by PID argument, if that is
3131 positive. Use PID instead of dead_child to know which process to
3132 reap. Wait for the child to die only if WNOHANG is not in
3134 (sys_select): Don't set dead_child.
3136 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3137 as it is no longer needed.
3139 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3141 (record_child_status_change): Remove the setting of
3142 record_at_most_one_child for the !WNOHANG case.
3144 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3146 Fix problems in ns port found by static checking.
3147 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3148 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3149 not to process group.
3150 (ns_select): Use emacs_write, not write, as that's more robust
3151 in the presence of signals.
3152 (fd_handler:): Check for read errors.
3154 2012-11-16 Glenn Morris <rgm@gnu.org>
3156 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3158 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3160 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3162 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3164 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3165 use the same value of thread handle.
3166 (start_timer_thread): If the timer thread exited (due to error),
3167 clean up by closing the two handles it used. Duplicate the caller
3168 thread's handle here, so it gets duplicated only once, when
3169 launching the timer thread. Set priority of the timer thread, not
3171 (getitimer): Don't duplicate the caller thread's handle here.
3174 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3176 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3179 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3181 Remove no-longer-used pty_max_bytes variable.
3182 * process.c (pty_max_bytes): Remove; unused.
3183 (send_process): Do not set it.
3185 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3187 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3188 Update dependencies.
3190 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3192 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3193 This follows up on the 2012-09-29 patch that removed indirection
3194 for the 'function' field. Reported by Sergey Vinokurov in
3195 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3197 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3199 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3200 different name, as the MS runtime does not have such a function,
3201 and probably never will.) All callers changed. Ignore DIRFD
3202 value if PATH is an absolute file name, to match Posix spec
3203 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3206 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3208 * xdisp.c (echo_area_display, redisplay_internal):
3209 Omit redundant check whether frame_garbaged is set.
3211 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3213 Use faccessat, not access, when checking file permissions (Bug#12632).
3214 This fixes a bug that has been present in Emacs since its creation.
3215 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3216 which must set some sort of record. (Torek's bug report was against
3217 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3218 same common flaw.) See Torek's Usenet posting
3219 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3220 Posted: Fri Apr 8 14:18:56 1983.
3221 * Makefile.in (LIB_EACCESS): New macro.
3223 * callproc.c (init_callproc):
3224 * charset.c (init_charset):
3225 * fileio.c (check_existing, check_executable, check_writable)
3227 * lread.c (openp, load_path_check):
3228 * process.c (allocate_pty):
3230 Use effective UID when checking permissions, not real UID.
3231 * callproc.c (init_callproc):
3232 * charset.c (init_charset):
3233 * lread.c (load_path_check, init_lread):
3234 Test whether directories are accessible, not merely whether they exist.
3235 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3236 * fileio.c (check_existing, check_executable, check_writable)
3238 Use symbolic names instead of integers for the flags, as they're
3240 (check_writable): New arg AMODE. All uses changed.
3241 Set errno on failure.
3242 (Ffile_readable_p): Use faccessat, not stat + open + close.
3243 (Ffile_writable_p): No need to call check_existing + check_writable.
3244 Just call check_writable and then look at errno. This saves a syscall.
3245 dir should never be nil; replace an unnecessary runtime check
3246 with an eassert. When checking the parent directory of a nonexistent
3247 file, check that the directory is searchable as well as writable, as
3248 we can't create files in unsearchable directories.
3249 (file_directory_p): New function, which uses 'stat' on most platforms
3250 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3251 (Ffile_directory_p, Fset_file_times): Use it.
3252 (file_accessible_directory_p): New function, which uses a single
3253 syscall for efficiency.
3254 (Ffile_accessible_directory_p): Use it.
3255 * xrdb.c (file_p): Use file_directory_p.
3256 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3257 * lread.c (openp): When opening a file, use fstat rather than
3258 stat, as that avoids a permissions race. When not opening a file,
3259 use file_directory_p rather than stat.
3260 (dir_warning): First arg is now a usage string, not a format.
3261 Use errno. All uses changed.
3262 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3263 that merely introduced a race.
3264 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3265 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3266 and similarly for the other O_* flags.
3267 * w32.c (sys_faccessat): Rename from sys_access and switch to
3268 faccessat's API. All uses changed.
3269 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3270 (magic_db): Rename from magic_file_p.
3271 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3272 char *, so that we don't have to test for file existence
3273 separately from opening the file for reading. This removes a race
3274 fixes a permission-checking problem, and simplifies the code.
3276 (file_p): Remove; no longer needed.
3278 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3280 Omit glyphs initialization at startup.

3291 passed to pint2str and pint2hrstr to be at most the size of the
3292 frame's decode_mode_spec_buffer. This avoids crashes with very
3293 large values of FIELD_WIDTH argument to decode_mode_spec.
3296 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3298 Fix a race with verify-visited-file-modtime (Bug#12863).
3299 Since at least 1991 Emacs has ignored an mtime difference of no
3300 more than one second, but my guess is that this was to work around
3301 file system bugs that were fixed long ago. Since the race is
3302 causing problems now, let's remove that code.
3303 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3304 whose time stamp is off by no more than a second. Insist that the
3305 file time stamps match exactly.
3307 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3309 * frame.h (struct frame): Convert external_tool_bar member to

3325 * xmenu.c (menubar_id_to_frame): Likewise.
3326 * xselect.c (frame_for_x_selection): Likewise.
3327 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3328 (x_window_to_menu_bar): Likewise.
3329 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3331 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3333 * data.c (Qdefalias_fset_function): Now static.
3335 Another tweak to vectorlike_header change.
3336 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3337 Remove, and replace all uses with ...
3338 (next_in_free_list, set_next_in_free_list):
3339 New functions, which respect C's aliasing rules better.
3341 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3343 * window.c (list4i): Rename from 'quad'. All uses changed.
3344 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3346 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3348 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3349 warning about mixing declarations and code in ISO C90.
3351 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3353 * window.c (Fsplit_window_internal): Set combination limit of
3354 new parent window to t iff Vwindow_combination_limit is t;
3355 fixing a regression introduced with the change from 2012-09-22.
3356 (Fset_window_combination_limit): Fix doc-string.
3358 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3360 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3361 amount when the scroll margins are too large. When scrolling
3362 backwards in the buffer, give up if cannot reach point or the
3363 scroll margin within a reasonable number of screen lines.
3364 Fixes point position in window under scroll-up/down-aggressively when
3365 point is positioned many lines beyond the window top/bottom.
3368 * ralloc.c (relinquish): If real_morecore fails to return memory
3369 to the system, don't crash; instead, leave the last heap
3370 unchanged and return. (Bug#12774)

3379 (Finteractive_form): Simplify.
3380 (Fquo): Don't insist on having at least 2 arguments.
3381 (Qdefalias_fset_function): New var.
3383 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3385 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3391 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3393 Fix recently introduced crash on MS-Windows (Bug#12839).
3394 * w32term.h (struct scroll_bar): Use convenient header.
3395 (SCROLL_BAR_VEC_SIZE): Remove.
3396 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3398 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3400 Tweak last vectorlike_header change.
3401 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3402 vectorlike object on the free list. This is introduced to avoid
3403 some (but not all) pointer casting and aliasing problems, see
3404 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3405 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3409 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3411 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3412 been removed, so remove them here also.
3414 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3416 * doc.c (Fdocumentation): Handle new property
3417 dynamic-docstring-function to replace the old ad-advice-info.
3419 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3421 * fns.c (Qeql, hashtest_eq): Now static.
3423 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3425 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3426 * fns.c (hashfn_eq, hashfn_eql, sxhash):

3437 special hash function containing a comparison that always yields 1.
3439 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3441 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3442 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3443 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3446 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3448 * image.c (xpm_make_color_table_h): Fix compiler error because
3449 make_hash_table changed.
3451 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3453 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3455 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3457 Use ad-hoc comparison function for the profiler's hash-tables.
3458 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3459 (make_log): Use them.
3460 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3461 call Fequal any more.

3470 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3471 (hash_lookup, hash_remove_from_table): Move assertion checking of
3472 hashfn result here. Check hash-equality before calling cmpfn.

3490 Shrink struct vectorlike_header to the only size field.
3491 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3493 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

3496 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3497 information from the vector header. Adjust comment.

3510 (Fmake_bool_vector): Likewise.
3511 (struct large_vector): New type to represent allocation unit for
3512 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3513 (large_vectors): Change type to struct large_vector.
3514 (allocate_vector_from_block): Simplify.
3515 (PSEUDOVECTOR_NBYTES): Replace with...

3521 (allocate_buffer): Use BUFFER_PVEC_INIT.
3522 (live_vector_p): Adjust to match large vector.
3523 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3524 * buffer.h (struct buffer): Add next member.
3525 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):

3533 (xvecsize): New command.
3535 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3537 * keyboard.c (event_to_kboard): Do not dereference
3538 frame_or_window field of SELECTION_REQUEST_EVENT
3539 and SELECTION_CLEAR_EVENT events (Bug#12814).
3540 * xterm.h (struct selection_input_event): Adjust comment.
3542 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3544 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3545 such as Scroll Lock, if the respective keys are treated as
3546 function keys, not as modifiers. This avoids destroying non-ASCII
3547 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3549 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3551 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3553 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3555 Restore some duplicate definitions (Bug#12814).
3556 This undoes part of the 2012-11-03 changes. Some people build
3557 with plain -g rather than with -g3, and they need the duplicate
3558 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3559 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3560 Define as macros, as well as as enums or as constants.
3562 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3564 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3565 to keypad keys (Bug#12816).
3567 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3569 Minor adjustments of recently-changed frame functions.
3570 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3571 known to be a frame (we're in the FRAMEP branch).
3572 * lisp.h (Qframep): Remove decl. frame.h declares this.
3573 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3574 since they're meant for Lisp fixnum values.
3576 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3578 * window.c (Fwindow_combination_limit): Revert to the only
3579 required argument and adjust docstring as suggested in
3580 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3581 by Martin Rudalics <rudalics@gmx.at>.
3583 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

3612 * xfaces.c (frame_or_selected_frame): Remove.
3613 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3614 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3615 (Fframe_face_alist): Use decode_live_frame.
3616 * xfns.c (check_x_frame): Likewise.
3618 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

3623 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3624 (Fwindow_line_height): Use it.
3625 (Fwindow_fringes): Use list3.
3626 (Fwindow_scroll_bars): Use list4.
3627 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3628 (Fwindow_combination_limit): Allow zero number of arguments.
3630 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3632 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3634 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3635 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3636 file descriptor 2 for standard error. (Bug#12805)
3638 2012-11-05 Chong Yidong <cyd@gnu.org>
3640 * process.c (wait_reading_process_output): Revert previous change.
3642 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3644 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3645 This removes code that has been obsolete since around 1990.
3646 * callproc.c (Fcall_process):
3648 * process.c (create_process):
3649 * term.c (dissociate_if_controlling_tty):
3650 Assume setsid exists.
3651 * callproc.c (child_setup): Assume setpgid exists and behaves as
3652 per POSIX.1-1988 or later.
3653 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3654 * emacs.c (shut_down_emacs):
3655 * sysdep.c (sys_suspend, init_foreground_group):
3656 Assume getpgrp behaves as per POSIX.1-1998 or later.
3657 * msdos.c (setpgrp): Remove.
3658 (tcgetpgrp, setpgid, setsid): New functions.
3659 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3660 * term.c (no_controlling_tty): Remove; unused.
3661 * w32proc.c (setpgrp): Remove.
3662 (setsid, tcgetpgrp): New functions.
3664 Simplify by assuming __fpending.
3665 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3666 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3667 Do not assume that __fpending's result fits in int.
3669 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3671 Remove EMACS_OUTQSIZE+sleep hack.
3672 * dispnew.c (update_frame_1): Remove hack for terminals slower
3673 than 2400 bps, which throttled Emacs by having it sleep.
3674 This code hasn't worked since at least 2007, when the multi-tty stuff
3675 was added, and anyway those old terminals are long dead.
3676 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3677 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3679 Fix data-loss with --version (Bug#9574).
3680 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3681 as we can't assume that emacs_strerror is initialized, and strerror
3682 is good enough here.
3683 (main): Invoke atexit earlier, to catch earlier instances of
3684 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3686 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3688 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3689 (keyDown): Remap keypad keys to X11 virtual key codes.
3691 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3693 Fix data-loss with --batch (Bug#9574).
3694 * emacs.c: Include <close-stream.h>.
3695 (close_output_streams): New function.
3696 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3697 and handles errors appropriately.
3698 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3701 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3702 The symptom is a diagnostic "GLib-WARNING **: In call to
3703 g_spawn_sync(), exit status of a child process was requested but
3704 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3705 waitpid(), so exit status can't be returned." The diagnostic
3706 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3707 The real bug is a race condition between Emacs and glib: Emacs
3708 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3709 so that glib can't find it. Work around the bug by invoking
3710 waitpid only on subprocesses that Emacs itself creates.
3711 * process.c (create_process, record_child_status_change):
3712 Don't use special value -1 in pid field, as the caller now must
3713 know the pid rather than having the callee infer it.
3714 The inference was sometimes incorrect anyway, due to another race.
3715 (create_process): Set new 'alive' member if child is created.
3716 (process_status_retrieved): New function.
3717 (record_child_status_change): Use it.
3718 Accept negative 1st argument, which means to wait for the
3719 processes that Emacs already knows about. Move special-case code
3720 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3721 processes that have already been waited for, by testing and
3722 clearing new 'alive' member.
3723 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3724 now does this internally.
3725 (handle_child_signal): Let record_child_status_change do all
3726 the work, since we do not want to reap all exited child processes,
3727 only the child processes that Emacs itself created.
3728 * process.h (Lisp_Process): New boolean member 'alive'.
3730 Omit duplicate definitions no longer needed with gcc -g3.
3731 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3732 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3733 Define only as macros. There's no longer any need to also define
3734 these symbols as enums or as constants, since we now assume
3735 gcc -g3 when debugging.
3737 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3739 * lisp.mk: Adjust comments to the fact that term/internal is now
3740 loaded from loadup.el.
3742 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3743 (msdos_fatal_signal): New function.
3744 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3747 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3748 for GCC versions before 4.
3749 (emacs_raise): Define to call msdos_fatal_signal.
3751 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3752 iterator when starting in the middle of a display or overlay
3755 2012-11-03 Chong Yidong <cyd@gnu.org>
3757 * process.c (wait_reading_process_output): Clean up the last
3760 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3762 * process.c (wait_reading_process_output): Avoid a race condition
3763 with SIGIO delivery (Bug#11536).
3765 2012-11-03 Chong Yidong <cyd@gnu.org>
3767 * buffer.c (cursor_type): Untabify docstring.
3769 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3771 * frame.h (struct frame): Drop can_have_scroll_bars member
3772 which is meaningless for a long time. Adjust comments.
3773 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3774 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3776 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3778 * window.c (decode_next_window_args): Update window arg after
3779 calling decode_live_window and so fix crash reported at
3780 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3781 by Juanma Barranquero <lekktu@gmail.com>.
3782 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3783 * font.c (Ffont_at): Likewise.
3785 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3787 * widget.c (resize_cb): New function.
3788 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3789 (EmacsFrameResize): Check if all is up to date before changing frame
3792 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3794 Implement backtrace output for fatal errors on MS-Windows.

3796 (BACKTRACE_LIMIT_MAX): New macro.
3797 (w32_backtrace): New function.
3798 (emacs_abort): Use w32_backtrace when the user chooses not to
3799 attach a debugger. Update the text of the abort dialog.
3801 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3803 Window-related stuff cleanup here and there.
3804 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3805 Use decode_any_window.
3806 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3807 * xdisp.c (Fformat_mode_line): Likewise.
3808 * font.c (Ffont_at): Use decode_live_window.
3809 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3810 * window.c (decode_next_window_args): Likewise.
3811 (decode_any_window): Remove static.
3812 * window.h (decode_any_window): Add prototype.
3813 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3814 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3817 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3819 Remove pad from struct input_event.
3820 * termhooks.h (struct input_event): Remove padding field.
3822 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3823 member is never cons for a long time. Adjust comment.
3824 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3825 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3826 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3827 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3829 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3831 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3833 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3835 Fix crash when using Emacs as commit editor for git (Bug#12697).
3836 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3837 and it is configured in conf_post.h.
3838 (Fcall_process): Don't invoke both setsid and setpgid; the former
3839 is enough, if it exists.
3840 * callproc.c (Fcall_process, child_setup):
3841 * process.c (create_process): Use setpgid.
3842 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3844 * dispnew.c (init_display): Initialize the foreground group
3845 if we are running a tty display.
3846 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3847 * lisp.h (init_foreground_group): New decl.
3848 * sysdep.c (inherited_pgroup): New static var.
3849 (init_foreground_group, tcsetpgrp_without_stopping)
3850 (narrow_foreground_group, widen_foreground_group): New functions.
3851 (init_sys_modes): Narrow foreground group.
3852 (reset_sys_modes): Widen foreground group.
3854 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3856 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3858 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3860 * minibuf.c (read_minibuf): Restore current buffer since
3861 choose_minibuf_frame calling Fset_frame_selected_window may
3862 change it (Bug#12766).
3864 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3866 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3868 2012-10-30 Kenichi Handa <handa@gnu.org>
3870 * font.c (Ffont_at): If WINDOW is specified and it is not
3871 displaying the current buffer, signal an error.
3873 2012-10-29 Daniel Colascione <dancol@dancol.org>
3875 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3876 In preparation for fixing bug#12739, move these functions from
3879 * coding.h, coding.c: ... to here, and compile them only when
3880 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3881 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3883 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3885 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3886 (timer_loop, getitimer, setitimer): Use it instead of
3887 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3889 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3892 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3894 * nsterm.m (NO_APPDEFINED_DATA): New define.
3895 (last_appdefined_event_data): New variable
3896 (last_appdefined_event): Remove.
3897 (ns_select): Initialize t from last_appdefined_event_data instead
3898 of [last_appdefined_event data1].
3899 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3900 remove last_appdefined_event (Bug#12698).
3902 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3904 * frame.c (x_set_font): Catch internal error.
3906 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3908 Avoid overflow in w32 implementation of interval timers.
3909 When possible, for ITIMER_PROF count only times the main thread
3911 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3912 'volatile ULONGLONG' types. All the other data which was
3913 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3914 (GetThreadTimes_Proc): New typedef.
3915 (w32_get_timer_time): New function, returns a suitable time value
3917 (timer_loop): Enter critical section when accessing ULONGLONG
3918 values of the itimer_data struct, as these accesses are no longer
3919 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3920 Remove unused variable.
3921 (init_timers): Initialize s_pfn_Get_Thread_Times.
3922 (start_timer_thread): Don't assign itimer->caller_thread here.
3923 (getitimer): Assign itimer->caller_thread here.
3924 (setitimer): Always call getitimer to get the value of ticks_now.
3925 (sys_spawnve): Avoid compiler warning about format mismatch.
3927 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3929 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3930 mouse movement events if the menu bar is active. This avoids
3931 producing a busy "hour-glass" cursor by Windows if the mouse
3932 pointer is positioned over a tooltip shown for some menu item.
3934 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3936 Don't assume process IDs fit in int.
3937 * emacs.c (shut_down_emacs) [!DOS_NT]:
3938 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3939 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3940 Use pid_t, not int, to store process IDs, as 'int'
3941 is not wide enough on a few platforms (e.g., AIX and IRIX).
3943 2012-10-23 Kenichi Handa <handa@gnu.org>
3945 The following change is to make face-font-rescale-alist work
3946 correctly for non-ASCII fonts.
3948 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3949 (font_open_for_lface): Handle Vface_font_rescale_alist.
3951 2012-10-23 Chong Yidong <cyd@gnu.org>
3953 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3955 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

3964 2012-10-21 Glenn Morris <rgm@gnu.org>
3966 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3968 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3970 Port to OpenBSD 5.1.
3971 * frame.c (Fmouse_position, Fmouse_pixel_position):
3972 * xdisp.c (produce_stretch_glyph):
3973 Declare local vars only when they're needed.
3974 This is clearer and avoids a warning on OpenBSD about unused vars.
3975 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3976 This is safer, and avoids OpenBSD warnings about unused vars.
3977 * keyboard.c (record_menu_key): Remove unnecessary decl.
3978 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3979 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3980 as our definition clashes with OpenBSD's.
3981 * xfaces.c (load_face_colors, check_lface_attrs)
3982 (get_lface_attributes_no_remap, get_lface_attributes)
3983 (lface_fully_specified_p, x_supports_face_attributes_p)
3984 (tty_supports_face_attributes_p, face_fontset, realize_face)
3985 (realize_x_face, realize_tty_face):
3986 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3987 merely Lisp_Object *. This is more informative and avoids
3988 a warning on OpenBSD about accessing beyond an object's size.
3990 2012-10-20 Chong Yidong <cyd@gnu.org>
3992 * lread.c (Fload): Doc fix (Bug#12592).
3994 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3996 * font.c (Ffont_at): Fix previous change.
3998 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4000 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.

4018 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4019 (staticpro): If we run out of staticpro slots, die with an
4020 informative error instead of just calling emacs_abort.
4022 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4024 Fix two flaws reported by Dmitry Antipov.
4025 * window.c (Ftemp_output_buffer_show): Remove.

4065 * cygw32.c (Fcygwin_convert_path_to_windows)
4066 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
4067 Lisp_Object values. (Bug#12661)

4142 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
4144 Fix some stat-related races.
4145 * fileio.c (Fwrite_region): Avoid race condition if a file is
4146 removed or renamed by some other process immediately after Emacs
4147 writes it but before Emacs stats it. Do not assume that stat (or
4149 * image.c (slurp_file): Resolve the file name with fopen + fstat

4176 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
4178 * fileio.c (check_existing): New function.
4179 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4180 instead of calling 'stat', when what's needed is to check whether
4181 a file exists. This avoids expensive system calls on MS-Windows.
4184 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
4186 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
4187 determine whether a file exists and is not a directory.
4189 * lisp.h (check_existing): Add prototype.
4191 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
4193 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.
4195 2012-10-12 Glenn Morris <rgm@gnu.org>

4222 (xmenu_show, xdialog_show):
4223 Use bool for booleans.
4224 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
4225 as it's not a predicate. All uses changed. Omit unnecessary
4228 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
4230 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
4231 (save_excursion_restore): Do not restore mark if it was not saved.
4233 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
4235 * marker.c (cached_modiff): EMACS_INT, not int.
4237 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
4238 instead of having a wrong decl.
4239 * nsmenu.m (waiting_for_input): Remove wrong decl.
4241 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4243 keyboard.c, keymap.c: Use bool for booleans.
4244 * dispnew.c (sit_for): Distinguish between 3-way display_option
4245 and boolean do_display.

4274 Use bool for boolean.
4275 * keyboard.c (timers_run, swallow_events)
4276 (detect_input_pending_run_timers):
4277 * process.c (wait_reading_process_output):
4278 Use unsigned for counter where wraparound-on-overflow is desired,
4279 since unsigned is guaranteed to have that behavior and signed is not.
4280 (read_char): Use ptrdiff_t for string length.
4281 (get_input_pending): Remove first argument, since it was always
4282 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4283 and behave as if it had that value. Return new value of
4284 input_pending. All callers changed.
4285 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4286 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4288 * keymap.c (push_key_description): Omit last arg, which was always 1.
4289 All callers changed.
4291 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4293 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4307 * termopts.h (flow_control, meta_key): Remove unused decls.
4308 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
4309 Don't include termopts.h.
4311 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4313 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4315 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4317 * commands.h (immediate_quit): Remove duplicate decl.
4319 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4321 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
4323 (nsfont_open): Remove setting of Vfonts_in_cache.
4324 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4326 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4328 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4329 match what GetLastError returns. Explain why the function is
4332 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4333 'is_tooltip_frame', to avoid confusion with its global namesake.
4335 2012-10-08 Daniel Colascione <dancol@dancol.org>
4337 * xdisp.c (start_hourglass): Call w32_note_current_window when
4338 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4339 build that caused Emacs to display the hourglass cursor forever.
4341 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4342 which is broken under remote desktop, calculate the number of
4343 colors available for a display based on the display's number of
4344 planes and number of bits per pixel per plane. (bug#10397).
4346 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4348 * nsfont.m (Vfonts_in_cache): New variable.
4349 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4350 are used. Add cached fonts to Vfonts_in_cache.
4351 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4353 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4355 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4357 (FONT_H): Define after FRAME_H.
4358 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4359 Update dependencies.
4361 * w32term.c: Remove leftover declaration of keyboard_codepage.
4363 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4365 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4366 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4367 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4368 (GLOBAL_SOURCES): Add cygw32.c.
4369 ($(BLD)/unexw32.$(O)):
4371 ($(BLD)/w32console.$(O)):
4372 ($(BLD)/w32fns.$(O)):
4373 ($(BLD)/w32heap.$(O)):
4374 ($(BLD)/w32menu.$(O)):
4375 ($(BLD)/w32proc.$(O)): Add w32common.h.
4377 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4379 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4381 2012-10-08 Daniel Colascione <dancol@dancol.org>
4383 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4384 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4385 accidental message numbering hole. Change other messages to
4388 * w32select.h (HAVE_W32SELECT): Remove.
4390 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4391 w32common.h instead of w32heap.h.
4393 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4394 (get_allocation_unit, get_processor_type, get_w32_major_version)
4395 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4396 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4397 (OS_NT, os_subtype, cache_system_info): Move declarations to
4400 * w32heap.c: Include w32common.h.
4401 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4402 (w32_minor_version, w32_build_number, w32_subtype):
4403 Remove duplicate definitions.
4405 * w32fns.c: Include w32common.h; include w32heap.h only in
4408 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4409 Use `report_file_error' instead of `error' in order to better
4410 inform users of what went wrong. Increase NTGUI_UNICODE file
4411 dialog box file name length to 32k, the maximum allowed by the NT
4414 * w32common.h: New file.
4415 (ROUND_UP, ROUND_DOWN, get_page_size)
4416 (get_allocation_unit, get_processor_type, get_w32_major_version)
4417 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4418 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4419 (OS_NT, os_subtype, cache_system_info): Move here.
4421 * unexw32.c, unexcw.c: Include w32common.h.
4423 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4424 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4425 to call syms_of_w32select.
4427 * cygw32.h: Remove obsolete EXFUN declarations.
4429 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4431 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4432 of w32inevt.o from SOME_MACHINE_OBJECTS.
4434 2012-10-08 Daniel Colascione <dancol@dancol.org>
4436 * image.c: Permanent fix for JPEG compilation issue --- limit
4437 jpeglib `boolean' redefinition to Cygwin builds.
4439 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4441 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4443 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4446 2012-10-08 Daniel Colascione <dancol@dancol.org>
4448 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4449 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4450 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4451 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4452 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4453 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4454 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4455 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4456 now a supported configuration.
4458 * Makefile.in: consolidate image variables into LIBIMAGE; add
4459 W32_OBJ and W32_LIBS. Compile new files.
4462 (_DebPrint) declare tracing facility for W32 debugging. We need
4463 to unify tracing later.
4465 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4466 unconditional use of W32 Unicode functions. Cygwin runs only on
4467 100% Unicode operating systems.
4469 * cygw32.c: New file. Define Cygwin-specific facilities.
4470 (Fcygwin_convert_path_to_windows)
4471 (Fcygwin_convert_path_from_windows): New user functions for
4472 accessing Cygwin path-munging routines.
4474 * cygw32.h: New file.
4475 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4476 UTF-16LE strings temporarily inside non-Lisp-visible string
4479 (w32_strerror): Just what it says on the tin.
4481 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4482 also run for Cygwin; both systems have the same problem with using
4483 GUI facilities in a forked child. Also call syms_of_cygw32,
4484 syms_of_w32select in correct places.
4486 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4487 needs fork-then-exec for daemon launching.
4489 * font.h: Include frame.h.
4491 * image.c: Use the image library cache machinery only when we're
4492 compiling for native WINDOWSNT; Cygwin can use shared libraries
4493 like any other Unixlike system.
4495 * keyboard.c: Clarify a comment regarding the input loop.
4497 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4498 functions directly instead of trying to detect at runtime that our
4499 host operating system supports them. We make this change for two
4500 reasons: Cygwin lacks support for the multibyte character
4501 conversion functions used by the legacy menu code, and Cygwin
4502 never needs to rely on non-Unicode APIs.
4504 * unexw32.c (hinst): Declare extern.
4506 * w32.c: Change header order;
4507 (w32_strerror): Move to w32fns.c because we need it for
4508 non-WINDOWSNT builds.
4510 * w32.h: Add #error macro to make sure we don't include w32.h for
4511 Cygwin builds. Remove w32select declarations.
4513 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4514 w32fns.c. w32console.c is WINDOWSNT-only.
4516 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4517 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4519 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4520 (w32_major_version, w32_minor_version, w32_build_number)
4521 (os_subtype, sound_type): Define here
4522 (w32_defined_color): Make color parameter const for consistency
4523 with other _defined_color functions.
4524 (w32_createwindow): Unconditionally call w32_init_class instead of
4525 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4526 through the code is complex and unnecessary because class
4527 registration is practically free.
4528 (w32_name_of_message): New EMACSDEBUG-only function.
4529 (Fset_message_beep): Move here
4530 (Fx_open_connection): Require that the display name for Windows be
4531 "w32" for consistency, emacsclient disambiguation, and maybe, one
4532 day, multi-window-system support.
4533 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4534 Cygwin files for W32 GUI facilities, since these clearly don't
4535 expect Cygwin names.
4536 (_DebPrint): Define.
4537 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4538 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4539 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4540 (w32_last_error): Remove.
4542 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4544 * w32heap.c (syspage_mask): Declare here.
4545 (cache_system_info): Remove.
4547 * w32inevt.c (faked_key): Define globally, not statically.
4548 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4549 (w32_console_toggle_lock_key): Move to w32fns.c.
4551 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4553 * w32proc.c (_DebPrint): Move to w32fns.c.
4554 * w32select.c: Include string.h, stdio.h for Cygwin.
4555 * w32select.h: New File.
4557 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4559 (w32_message_fd): New variable. Under Cygwin, holds the file
4560 descriptor the system used to tell us about pending thread
4563 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4564 that prevented compilation under non-WINDOWSNT systems.
4566 (w32_initialize): Open /dev/windows and assign it to
4567 w32_message_fd. Provide w32 feature.
4569 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4570 (WM_EMACS_INPUT_READY): add.
4571 (prepend_msg, w32_message_fd): Declare globally.
4574 (keyboard_handle): Use only when WINDOWSNT.
4575 (notify_msg_ready): New function. Posts a message to the main
4576 thread's message queue under CYGWIN, which wakes up the main
4577 thread from select(2) by making the /dev/windows file descriptor
4578 ready. Under WINDOWSNT, it sets an event the same way the old
4581 (post, prepend_msg): Actually call notify_msg_ready instead of
4582 setting the input event directly.
4584 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4586 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4587 but it still has blocs in it, don't return it to the system,
4588 instead of aborting. (Bug#12402)
4590 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4592 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4594 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4595 MAC_OS_X_VERSION_10_6.
4596 (syms_of_nsterm): Remove comment about Panther and above for
4598 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4599 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4600 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4602 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4603 MAC_OS_X_VERSION_10_4.
4605 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4606 MAC_OS_X_VERSION_10_2.
4608 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4610 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4611 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4613 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4614 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4615 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4616 Remove ns_in_resize check.
4617 (ns_clear_frame_area): Remove resize handle code.
4619 * nsfns.m (ns_in_resize): Remove.
4620 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4621 Remove ns_in_resize check.
4623 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4625 Improve sys_siglist detection.
4626 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4627 defined as a macro, as is done in Solaris.
4628 (sys_siglist_entries): New macro.
4629 (save_strsignal): Use it.
4630 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4631 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4633 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4635 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4636 fullscreen/Fullscreen.
4638 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4639 tobar_height is new.
4641 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4642 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4643 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

4658 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4660 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4662 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4663 that time stamps of directories could also be changed.
4664 Don't request the too broad GENERIC_WRITE, only the more restrictive
4665 FILE_WRITE_ATTRIBUTES access rights.
4667 * fileio.c (Fset_file_times): Special-case ignoring errors for
4668 directories only on MSDOS, not on MS-Windows.
4670 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4672 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4674 2012-10-04 Eli Zaretskii <eliz@gnu.org>

4677 see whether CreateFile failed.
4679 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4681 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4682 to avoid similar races.
4683 * keyboard.c (pending_signals): Now bool, not int.
4685 Port timers to OpenBSD, plus check for timer failures.
4686 OpenBSD problem reported by Han Boetes.
4687 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4689 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4690 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4691 like OpenBSD, which has timer_settime but does not declare it.
4692 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4693 whether to use itimerspec-related primitives. All uses of
4694 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4696 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4698 * profiler.c (handle_profiler_signal): Fix a malloc race
4699 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4701 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4703 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4705 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4707 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4708 consistent with the change in return value of 'safe_strsignal'.
4710 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4712 Prefer plain 'static' to 'static inline' (Bug#12541).

4714 (bidi_set_sor_type, bidi_push_embedding_level)
4715 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

4720 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4721 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4722 Now 'static', not 'static inline'.
4724 Count overruns when profiling; change units to ns.
4725 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4726 Give extra weight to samples after overruns, to attempt to count
4727 the time more accurately.
4728 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4729 the underlying primitives nominally do ns.
4730 (Fprofiler_cpu_start): Document the change. Mention that
4731 the sampling intervals are only approximate.
4733 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4735 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4737 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4738 case for the special 0 coding-system.
4740 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4741 (Fmake_overlay): Remove redundant tests.
4742 (fix_start_end_in_overlays): Remove redundant recentering.
4744 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4746 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4747 Update dependencies.
4749 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4751 Fix a malloc race condition involving strsignal.
4752 A signal can arrive in the middle of a malloc, and Emacs's signal
4753 handler can invoke strsignal, which can invoke malloc, which is
4754 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4755 Fix it by altering the signal handler so that it does not invoke
4757 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4758 * process.c (status_message): Use const pointer, in case strsignal
4759 is #defined to safe_strsignal.
4760 * sysdep.c (sys_siglist, init_signals): Always define and
4761 initialize a substitute sys_siglist if the system does not define
4762 one, even if HAVE_STRSIGNAL.
4763 (safe_strsignal): Rename from strsignal. Always define,
4764 using sys_siglist. Return a const pointer.
4765 * syssignal.h (safe_strsignal): New decl.
4766 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4768 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4770 * w32proc.c (timer_loop): Fix code that waits for timer
4771 expiration, to avoid high CPU usage.
4773 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4775 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4776 (sweep_weak_table): Remove redundant prototypes.
4778 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4780 * emacs.c: Move the inclusion of TERM_HEADER after including
4781 windows.h on WINDOWSNT. This avoids compilation problems with
4784 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4786 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4787 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4788 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4789 as the previous version used 'void *'.
4791 * ralloc.c (ROUNDUP): Fix last change.
4792 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4795 * w32proc.c <disable_itimers>: New static flag.
4796 (init_timers): Initialize it to zero, after creating the critical
4797 sections used by the timer threads.
4798 (term_timers): Set to 1 before deleting the critical sections.
4799 (getitimer, setitimer): If disable_itimers is non-zero, return an
4800 error indication without doing anything. Reported by Fabrice
4801 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4802 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4804 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4807 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4808 term_ntproc after all the other bookkeeping, to get timers working
4809 as long as possible.
4811 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4813 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4814 Suggested by Juri Linkov in
4815 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4817 Prefer plain 'static' to 'static inline' (Bug#12541).
4818 With static functions, modern compilers inline pretty well by
4819 themselves; advice from programmers often hurts as much as it helps.
4820 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4821 this change shrinks the text size of the Emacs executable by 1.1%
4822 without affecting CPU significantly in my benchmark.
4823 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4903 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4905 Revert the FOLLOW-SYMLINKS change for file-attributes.
4906 Doing it right would require several changes to Tramp, and there's
4907 not enough time to get that tested before the freeze today.
4908 * dired.c (directory_files_internal, Ffile_attributes):
4911 * frame.c (x_report_frame_params): Port better to wider ints.
4912 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4913 or that pointers can be printed in 15 decimal digits.
4914 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

5038 2012-09-30 Kenichi Handa <handa@gnu.org>
5040 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
5041 to the buffer relocation which may be caused by ccl_driver.

5083 2012-09-30 Chong Yidong <cyd@gnu.org>
5085 * fns.c (Frandom): Doc fix.
5087 2012-09-30 Martin Rudalics <rudalics@gmx.at>
5089 * window.c (Vwindow_combination_limit): New default value.
5090 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
5092 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5094 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
5095 Suggested by Eli Zaretskii in
5096 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5098 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5100 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5101 HAVE_TIMER_SETTIME is defined.
5103 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5105 Profiler improvements: more-accurate timers, overflow checks.
5106 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5107 signal.h, setjmp.h. Include systime.h instead.
5108 (saturated_add): New function.
5109 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
5110 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
5111 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
5113 (enum profiler_cpu_running): New enum.
5114 (profiler_cpu_running): Now of that enum type, not bool.
5115 All uses changed to store the new value.
5116 (handle_profiler_signal): Rename from sigprof_handler_1,
5117 for consistency with other handlers. Do not check whether
5118 cpu_log is a hash-table if garbage collecting, since it
5119 doesn't matter in that case.
5120 (deliver_profiler_signal): Rename from sigprof_handler,
5121 for consistency with other handlers.
5122 (setup_cpu_timer): New function, with much of what used to be in
5123 Fprofiler_cpu_start. Check for out-of-range argument.
5124 Prefer timer_settime if available, and prefer
5125 thread cputime clocks, then process cputime clocks, then
5126 monotonic clocks, to the old realtime clock. Use make_timeval
5127 to round more-correctly when falling back to setitimer.
5128 (Fprofiler_cpu_start): Use it.
5129 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5130 Don't assume that passing NULL as the 2nd argument of setitimer
5131 is the same as passing a pointer to all-zero storage.
5132 Ignore SIGPROF afterwards.
5133 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5134 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5135 non-fatal signal handlers. Ignore SIGPROF on startup.
5136 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5137 in profiler.c, since sysdep.c now uses it.
5139 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5140 Suggested by Eli Zaretskii in
5141 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
5143 2012-09-29 Juanma Barranquero <lekktu@gmail.com>
5145 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
5147 2012-09-29 Stefan Monnier <monnier@iro.umontreal.ca>

5151 * profiler.c (record_backtrace, sigprof_handler_1):
5152 * alloc.c (Fgarbage_collect):
5153 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
5154 (Fbacktrace_frame): Adjust accordingly.
5156 2012-09-28 Glenn Morris <rgm@gnu.org>
5158 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5159 (Frun_hook_with_args_until_failure): Doc fixes.
5161 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5163 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
5164 Qautomatic_redisplay and change the symbol name. All users changed.
5166 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
5168 * profiler.c (sigprof_handler): Fix race condition.
5170 2012-09-28 Glenn Morris <rgm@gnu.org>

5174 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
5176 Check more robustly for timer_settime.
5177 * Makefile.in (LIB_TIMER_TIME): New macro.
5179 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
5180 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
5183 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
5185 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.
5187 2012-09-26 Juanma Barranquero <lekktu@gmail.com>
5189 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
5191 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
5193 * character.h (MAYBE_UNIFY_CHAR): Remove.
5194 * charset.c, charset.h (maybe_unify_char): Now static.
5195 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5196 Since this stuff is now private to charset.c, there's no need for
5197 a public macro and no need to inline by hand.
5199 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
5200 Stefan Monnier <monnier@iro.umontreal.ca>
5201 Juanma Barranquero <lekktu@gmail.com>

5209 (MALLOC_PROBE): New macro.
5210 (xmalloc, xzalloc, xrealloc, lisp_malloc, lisp_align_malloc): Use it.
5211 (total_bytes_of_live_objects): New function.
5212 (Fgarbage_collect): Use it. Record itself in backtrace_list.
5213 Call malloc_probe for the memory profiler.

5226 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5228 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5230 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5232 Prefer POSIX timers if available.
5233 They avoid a race if the timer is too close to the current time.
5234 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5235 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5236 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5238 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5240 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
5241 CHAR_STRING_ADVANCE.
5242 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5243 STRING_CHAR_ADVANCE.
5245 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5247 Move Vlibrary_cache to emacs.c and reset before dumping.
5249 * lisp.h (reset_image_types): Declare.
5250 [WINDOWSNT] (Vlibrary_cache): Declare.
5252 * image.c (reset_image_types): New function.
5254 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5255 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
5256 (Fdump_emacs): Reset Vlibrary_cache and image_types.
5258 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
5259 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5261 * w32.h (Vlibrary_cache): Do not declare.
5263 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5265 * w32proc.c (sys_signal): Handle all signals defined by the
5266 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5267 handlers for signals supported by Windows. Don't override
5268 term_ntproc as the handler for SIGABRT.
5269 (sigaction): Rewrite to call sys_signal instead of duplicating its
5271 (sys_kill): Improve commentary.
5273 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5274 consistency with a signature of a signal handler. All callers
5276 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5277 install term_ntproc as a signal handler for SIGABRT, as that
5278 should be done by the dumped Emacs.
5280 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5282 * w32select.c (term_w32select): Protect against repeated
5283 invocation by setting clipboard_owner to NULL after calling
5286 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5287 and term_ntproc to their modified signatures.
5289 * character.c (char_string, string_char): Remove calls to
5290 MAYBE_UNIFY_CHAR. See the discussion starting at
5291 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5294 2012-09-25 Chong Yidong <cyd@gnu.org>
5296 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5298 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5300 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5301 when encountering an unknown bytecode.
5303 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5305 image.c, indent.c: Use bool for booleans.
5306 * dispextern.h (struct image_type): Members valid_p, load, init
5307 now return bool, not int. All uses changed.
5308 * image.c: Omit unnecessary static decls.
5309 (x_create_bitmap_mask, x_build_heuristic_mask):
5310 Return void, not int, since callers don't care about the return value.

5339 Use bool for booleans.
5341 2012-09-24 Chong Yidong <cyd@gnu.org>
5343 * chartab.c (Fset_char_table_default): Obsolete function removed.
5345 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5347 Move pid_t related decls out of lisp.h.
5348 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5349 (interruptible_wait_for_termination):
5350 Move these decls from lisp.h to syswait.h, since they use pid_t.
5351 Needed on FreeBSD; see Herbert J. Skuhra in
5352 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5353 * callproc.c: Include syswait.h.
5355 gnutls.c, gtkutil.c: Use bool for boolean.

5371 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5372 * xfns.c (Fx_show_tip) [USE_GTK]:
5373 Use bool for boolean.
5374 * gtkutil.c (xg_update_frame_menubar):

5399 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5401 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5402 fatal_error_backtrace.
5404 * w32proc.c (sys_kill): Undo last change: don't do anything when
5405 invoked to deliver SIGABRT to our own process. This is now
5406 handled by emacs_raise.
5408 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5410 * w32term.c (w32_read_socket): Remove leftover reference to
5411 interrupt_input_pending.
5413 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5415 Do not use SA_NODEFER.
5416 Problem reported by Dani Moncayo in
5417 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5419 * sysdep.c (emacs_abort): Do not reset signal handler.
5420 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5421 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5422 wanted even on POSIXish hosts, and it doesn't work on Windows.
5424 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5426 * xterm.c (x_term_init): Call fixup_locale before and after calling
5427 gtk_init (Bug#12392).
5429 2012-09-23 Chong Yidong <cyd@gnu.org>
5431 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5432 Vdynamic_library_alist.
5434 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5435 (Fgnutls_available_p): Caller changed.
5437 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5438 (Flibxml_parse_xml_region): Likewise.
5440 * dispextern.h (struct image_type): Remove arg from init function.
5442 * image.c (Finit_image_library, lookup_image_type)
5443 (define_image_type): Remove now-unneeded second arg.
5444 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5445 (init_tiff_functions, init_gif_functions, init_svg_functions):
5446 Arglist and w32_delayed_load calling convention changed.
5447 (gs_type): Remove init_gs_functions; there is no such function.
5448 (valid_image_p, make_image): Fix caller to lookup_image_type.
5450 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5452 Simplify and avoid signal-handling races (Bug#12471).
5454 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5455 Avoid recursive loop if there's a fatal error in the function itself.
5456 * atimer.c (pending_atimers):
5457 * blockinput.h: Don't include "atimer.h"; no longer needed.
5458 (interrupt_input_pending): Remove. All uses removed.
5459 pending_signals now counts both atimers and ordinary interrupts.
5460 This is less racy than having three separate pending-signal flags.
5461 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5463 Rename from their upper-case counterparts BLOCK_INPUT,
5464 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5465 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5466 This makes it easier to access volatile variables more accurately.
5467 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5468 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5469 that's more reliable if the code is buggy and sets
5470 interrupt_input_blocked to a negative value. All uses changed.
5471 * atimer.c (deliver_alarm_signal):
5472 Remove. No need to deliver this to the parent; any thread can
5473 handle this signal now. All uses replaced by underlying handler.
5474 * atimer.c (turn_on_atimers):
5475 * dispnew.c (handle_window_change_signal):
5476 * emacs.c (handle_danger_signal):
5477 * keyboard.c (kbd_buffer_get_event):
5478 Don't reestablish signal handler; not needed with sigaction.
5479 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5481 Rework to avoid unnecessary accesses to volatile variables.
5482 (UNBLOCK_INPUT_TO): Now a function.
5483 (totally_unblock_input, unblock_input): New decls.
5484 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5485 (init_data): Remove. Necessary stuff now done in init_signal.
5486 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5487 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5488 (fatal_error_code): Remove; no longer needed.
5489 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5490 it doesn't always backtrace. All uses changed. No need to reset
5491 signal to default, since sigaction and/or die does that for us now.
5492 Use emacs_raise (FOO), not kill (getpid (), FOO).
5493 (main): Check more-accurately whether we're dumping.
5494 Move fatal-error setup to sysdep.c
5495 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5496 * gtkutil.c (xg_get_file_name, xg_get_font):
5497 Remove no-longer-needed signal-mask manipulation.
5498 * keyboard.c, process.c (POLL_FOR_INPUT):
5499 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5500 * keyboard.c (read_avail_input): Remove.
5501 All uses replaced by gobble_input.
5502 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5503 (kbd_buffer_store_event_hold, gobble_input):
5504 (record_asynch_buffer_change) [USABLE_SIGIO]:
5505 (store_user_signal_events):
5506 No need to mess with signal mask.
5507 (gobble_input): If blocking input and there are terminals, simply
5508 set pending_signals to 1 and return. All hooks changed to not
5509 worry about whether input is blocked.
5510 (process_pending_signals): Clear pending_signals before processing
5511 them, in case a signal comes in while we're processing.
5512 By convention callers now test pending_signals before calling us.
5513 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5514 New functions, to support changes to blockinput.h.
5515 (handle_input_available_signal): Now extern.
5516 (reinvoke_input_signal): Remove. All uses replaced by
5518 (quit_count): Now volatile, since a signal handler uses it.
5519 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5520 All callers changed. Block SIGINT only if not already blocked.
5521 Clear sigmask reliably, even if Fsignal returns, which it can.
5522 Omit unnecessary accesses to volatile var.
5523 (quit_throw_to_read_char): No need to restore sigmask.
5524 * keyboard.c (gobble_input, handle_user_signal):
5525 * process.c (wait_reading_process_output):
5526 Call signal-handling code rather than killing ourselves.
5527 * lisp.h: Include <float.h>, for...
5528 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5529 (pending_signals): Now volatile.
5530 (syms_of_data): Now const if IEEE floating point.
5531 (handle_input_available_signal) [USABLE_SIGIO]:
5532 (terminate_due_to_signal, record_child_status_change): New decls.
5533 * process.c (create_process): Avoid disaster if memory is exhausted
5534 while we're processing a vfork, by tightening the critical section
5536 (send_process_frame, process_sent_to, handle_pipe_signal)
5537 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5539 (send_process): No need for setjmp/longjmp any more, since the
5540 SIGPIPE stuff is now gone. Instead, report an error if errno
5542 (record_child_status_change): Now extern. PID and W are now args.
5543 Return void, not bool. All callers changed.
5544 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5545 Remove. All uses removed. This bug should be fixed now in a
5547 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5548 and record the child status change directly. This avoids the
5549 need to futz with the signal mask.
5550 (process_fatal_action): Move here from emacs.c.
5551 (emacs_sigaction_flags): New function, containing
5552 much of what used to be in emacs_sigaction_init.
5553 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5554 caught by emacs, to make races less likely.
5555 (deliver_process_signal): Rename from handle_on_main_thread.
5557 (BACKTRACE_LIMIT_MAX): Now at top level.
5558 (thread_backtrace_buffer, threadback_backtrace_pointers):
5560 (deliver_thread_signal, deliver_fatal_thread_signal):
5561 New functions, for more-accurate delivery of thread-specific signals.
5562 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5563 (deliver_arith_signal): Handle in this thread, not
5564 in the main thread, since it's triggered by this thread.
5565 (maybe_fatal_sig): New function.
5566 (init_signals): New arg DUMPING so that we can be more accurate
5567 about whether we're dumping. Caller changed.
5568 Treat thread-specific signals differently from process-general signals.
5569 Block all signals while handling fatal error; that's safer.
5570 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5572 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5573 Ignore SIGPIPE unless batch.
5574 (emacs_backtrace): Output backtrace for the appropriate thread,
5575 which is not necessarily the main thread.
5576 * syssignal.h: Include <stdbool.h>.
5577 (emacs_raise): New macro.
5578 * xterm.c (x_connection_signal): Remove; no longer needed
5579 now that we use sigaction.
5580 (x_connection_closed): No need to mess with sigmask now.
5581 (x_initialize): No need to reset SIGPIPE handler here, since
5582 init_signals does this for us now.
5584 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5586 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5587 background rect may be larger (Bug#12245).
5589 2012-09-23 Chong Yidong <cyd@gnu.org>
5591 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5593 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5595 * .gdbinit: Just stop at fatal_error_backtrace.
5596 See Stefan Monnier's request in
5597 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5598 Remove no-longer-used query of system type.
5600 2012-09-22 Chong Yidong <cyd@gnu.org>
5602 * search.c (Freplace_match): Doc fix (Bug#12325).
5604 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5606 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5607 (Fline_end_position): Doc fix.
5609 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5611 2012-09-22 Chong Yidong <cyd@gnu.org>
5613 * dispextern.h (struct image_type): Add new slot, storing a type
5614 initialization function.
5616 * image.c (define_image_type): Call the image initializer function
5617 if it is defined. Arguments and return value changed.
5618 (valid_image_p, make_image): Callers changed.
5619 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5620 (gif_type, imagemagick_type, svg_type, gs_type):
5621 Add initialization functions.
5622 (Finit_image_library): Call lookup_image_type.
5623 (CHECK_LIB_AVAILABLE): Macro deleted.
5624 (lookup_image_type): Call define_image_type here, rather than via
5625 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5626 (syms_of_image): Move define_image_type calls for xbm_type and
5627 pbm_type to lookup_image_type.
5629 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5631 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5632 'idle_timers' from here ...
5633 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5634 lists, to avoid infloops when the timer does something stupid,
5635 like reinvoke itself with the same or smaller time-out.
5638 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5640 * window.c (Fsplit_window_internal): Handle only Qt value of
5641 Vwindow_combination_limit separately.
5642 (Qtemp_buffer_resize): New symbol.
5643 (Vwindow_combination_limit): New default value.
5646 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5648 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5649 the new overlay string. (Bug#10159)
5651 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5653 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5654 or that fprintf is async-signal-safe. POSIX doesn't require
5657 2012-09-22 Chong Yidong <cyd@gnu.org>
5659 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5662 2012-09-22 Kenichi Handa <handa@gnu.org>
5664 * composite.c (composition_reseat_it): Handle the case that a
5665 grapheme cluster is not covered by a single font (Bug#12352).
5667 2012-09-21 Chong Yidong <cyd@gnu.org>
5669 * image.c (define_image_type): Avoid adding duplicate types to
5670 image_types (Bug#12463). Suggested by Jörg Walter.
5672 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5674 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5675 (print_load_command_name): Add case LC_DATA_IN_CODE.
5676 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5678 2012-09-21 Glenn Morris <rgm@gnu.org>
5680 * eval.c (Frun_hook_with_args_until_success)
5681 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5683 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5685 * fileio.c (Ffile_selinux_context): Only call freecon when
5686 lgetfilecon succeeded.
5687 (Fset_file_selinux_context): Likewise. (Bug#12444)
5689 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5691 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5692 reordering, locate the cursor by calling set_cursor_from_row; if
5693 that fails, clear the desired glyph matrix before returning a
5694 failure indication to the caller. Fixes leaving garbled display
5695 when fast scrolling with a down-key. (Bug#12403)
5696 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5697 scrolling through multibyte text.
5699 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5701 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5702 calling mark_vectorlike since that's the one that marks the window.
5703 (mark_discard_killed_buffers): Mark the final cdr.
5704 * window.h (struct window): Move prev/next_buffers to the
5705 non-standard fields.
5706 * window.c (make_window): Initialize prev/next_buffers manually.
5708 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5710 Omit unused arg EXPECTED from socket hooks.
5711 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5712 * nsterm.m (ns_term_init):
5713 * termhooks.h (struct terminal.read_socket_hook):
5714 * w32inevt.c (w32_console_read_socket):
5715 * w32term.c (w32_read_socket):
5716 * xterm.c (XTread_socket):
5717 Omit unused arg EXPECTED. All callers changed.
5718 (store_user_signal_events): Return void, not int, since callers no
5719 longer care about the return value. All uses changed.
5721 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5723 * w32gui.h (XParseGeometry): Do not declare.
5725 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5727 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5728 Ignore 'expected'. See Eli Zaretskii in
5729 <http://bugs.gnu.org/12471#8> (last line).
5731 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5732 (XParseGeometry): Now static. Substitute extremal values for
5733 values that are out of range.
5735 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5737 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5739 * nsfns.m (XParseGeometry): Remove.
5740 (Fx_create_frame): Call x_set_offset to correctly interpret
5741 top_pos in geometry.
5743 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5744 (Fx_parse_geometry): If there is a space in string, call
5745 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5747 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5749 * search.c (scan_buffer): Use character positions in calls to
5750 region_cache_forward and region_cache_backward, not byte
5751 positions. (Bug#12196)
5753 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5754 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5756 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5757 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5758 emacs_blocked_malloc, now deleted.
5760 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5762 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5763 The workaround was for improving performance on Solaris 2.4, but
5764 is getting in the way now. Emacs will still work if someone is
5765 still running Solaris 2.4 in a museum somewhere; Sun dropped
5766 support for Solaris 2.4 in 2003.
5767 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5768 * process.c (create_process) [HAVE_WORKING_VFORK]:
5769 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5770 since Emacs no longer uses vfork on that platform.
5772 2012-09-17 Glenn Morris <rgm@gnu.org>
5774 * emacs.c: Use COPYRIGHT.
5776 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5778 Remove configure's --without-sync-input option (Bug#12450).
5779 When auditing signal-handling in preparation for cleaning it up,
5780 I found that SYNC_INPUT has race conditions and would be a real
5781 pain to fix. Since it's an undocumented and deprecated
5782 configure-time option, now seems like a good time to remove it.
5783 Also see <http://bugs.gnu.org/11080#16>.
5784 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5785 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5786 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5787 (malloc_hysteresis):
5788 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5789 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5790 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5791 (dont_register_blocks, bytes_used_when_reconsidered)
5792 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5793 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5794 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5795 Remove. All uses removed.
5796 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5797 implementation, one that depends on whether the new macro
5798 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5800 * atimer.c (run_timers, handle_alarm_signal):
5801 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5802 (handle_async_input, process_pending_signals)
5803 (handle_input_available_signal, init_keyboard):
5804 * nsterm.m (ns_read_socket):
5805 * process.c (wait_reading_process_output):
5806 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5807 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5809 * xterm.c (XTread_socket):
5811 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5812 * eval.c (handling_signal): Remove. All uses removed.
5813 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5814 All uses replaced with the SYNC_INPUT version.
5815 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5817 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5820 * font.c (Ffont_shape_gstring): Remove unused local.
5822 2012-09-16 Glenn Morris <rgm@gnu.org>
5824 * Makefile.in (clean): No longer run nextstep's clean.
5826 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5828 (ns-app): Move here from ns.mk, and simplify.
5829 (clean): Simplify nextstep entry.
5830 * ns.mk: Remove file.
5832 2012-09-17 Kenichi Handa <handa@gnu.org>
5834 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5835 not covert the last few charactes.
5837 2012-09-16 Kenichi Handa <handa@gnu.org>
5839 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5840 here, but just check the validity of glyphs in the glyph-string.
5842 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5844 * window.c (Fwindow_parameter, Fset_window_parameter):
5845 Accept any window as argument (Bug#12452).
5847 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5849 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5850 to ns_term_init to avoid memory leak.
5852 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5853 explicit retain/release.
5854 (ns_term_init): Only allow one display. Initialize outerpool and
5857 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5859 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5860 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5861 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5862 the Microsoft problem in a different way, by altering ../nt/config.nt.
5864 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5879 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5880 by lisp.h. This completes removal of setjmp.h inclusion
5881 erroneously announced in the previous commit. (Bug#12446)
5883 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5886 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5887 not defined as a macro. The latter happens on MS-Windows.
5890 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5892 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5893 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5894 Some instances of '#include <setjmp.h>' removed, if the
5895 only reason for the instance was because "lisp.h" was included.
5896 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5897 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5898 and _longjmp with the new symbols. Emacs already uses _setjmp if
5899 available, so this change affects only POSIXish hosts that have
5900 sigsetjmp but not _setjmp, such as some versions of Solaris and
5901 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5902 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5903 (png_load_body) [HAVE_PNG]:
5904 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5905 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5906 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5907 since PNG requires jmp_buf. This is the only exception to the
5908 general rule that we now use sys_setjmp and sys_longjmp.
5909 This exception is OK since this code does not change the signal
5910 mask or longjmp out of a signal handler.
5912 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5914 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5915 Include "syssignal.h", for 'main_thread'.
5917 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5919 Avoid out-of-range marker position (Bug#12426).
5920 * insdel.c (replace_range, replace_range_2):
5921 Adjust markers before overlays, as suggested by comments.
5922 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5923 Remove redundant check before calling offset_intervals.
5925 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5927 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5928 current buffer (Bug#12387).
5930 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5932 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5934 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5936 Use a more backwards-compatible timer format (Bug#12430).
5937 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5938 vector element, not from the 4th, since PSECS is now at the end.
5939 (Fcurrent_idle_time): Doc fix.
5941 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5943 Function to mark objects and remove killed buffers at once.
5944 * alloc.c (discard_killed_buffers): Rename to ...
5945 (mark_discard_killed buffers) ... new name. Add marking
5946 of remaining objects. Fix comment. Adjust users.
5947 (mark_object): Do not touch frame buffer lists here.
5948 * frame.c (delete_frame): Reset frame buffer lists here.
5950 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5952 Better workaround for GNOME bug when --enable-gcc-warnings.
5953 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5954 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5955 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5957 Simplify SIGIO usage (Bug#12408).
5958 The code that dealt with SIGIO was crufty and confusing, e.g., it
5959 played tricks like "#undef SIGIO" but these tricks were not used
5960 consistently. Simplify mostly by not #undeffing standard symbols,
5961 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5962 or not as we please) rather than "defined SIGIO" (standard symbol
5963 that we probably shouldn't #undef).
5964 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5965 Modules that need it can include it.
5966 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5967 * dispextern.h (ignore_sigio): New decl.
5968 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5969 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5970 * emacs.c (shut_down_emacs):
5971 * keyboard.c (kbd_buffer_store_event_hold):
5972 Use ignore_sigio rather than invoking 'signal' directly.
5973 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5975 (FIONREAD, SIGIO): Do not #undef.
5976 (tty_read_avail_input): Use #error rather than a syntax error.
5977 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5978 for I_PIPE, used by SETUP_SLAVE_PTY.
5979 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5980 * sysdep.c (croak): Remove; no longer needed. This bit of
5981 temporary code, with Fred N. Fish's comment that it's temporary,
5982 has been in Emacs since at least 1992!
5983 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5984 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5985 * syssignal.h (croak): Remove decl.
5986 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5987 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5988 now that we're termios-only.
5989 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5990 * term.c (dissociate_if_controlling_tty): Use #error rather than
5993 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5994 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5995 to work around GNOME bug 683906.
5996 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5997 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5998 This works around GCC bug 54561.
6000 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6002 More fixes for 'volatile' and setjmp/longjmp.
6003 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6004 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6005 (png_load_body) [HAVE_PNG]:
6006 (jpeg_load_body) [HAVE_JPEG]:
6007 New function, with most of the old parent function's body.
6008 (png_load) [HAVE_PNG]:
6009 (jpeg_load) [HAVE_JPEG]:
6010 Invoke the new function, to avoid longjmp munging our locals.
6011 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6012 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6013 longjmp is passed 2, as the C standard doesn't guarantee this.
6014 Instead, store the failure code into mgr->failure_code.
6016 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6018 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6019 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6020 (syms_of_keyboard): Remove support for unread-command-char.
6022 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6024 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6025 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6026 violation. (Bug#12426)
6028 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6030 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6032 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6034 * eval.c: Add `inhibit-debugger'.
6035 (Qinhibit_debugger): New symbol.
6036 (call_debugger): Bind it instead of Qdebug_on_error.
6037 (maybe_call_debugger): Test Vinhibit_debugger.
6038 (syms_of_eval): Define inhibit-debugger.
6039 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6040 (syms_of_xdisp): Remove inhibit-debug-on-message.
6042 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6044 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6045 If a nonvolatile local variable is written before a _longjmp to
6046 the frame containing the variable, and is read after the _longjmp,
6047 the value read is indeterminate. Some local variables of type
6048 'struct handler' and 'struct catchtag' are used in this way, so
6049 mark each of their slots as volatile if the slot can be set before
6050 _longjmp and read afterwards.
6051 * lisp.h (struct handler): var and chosen_clause are now volatile.
6052 (struct catchtag): val, next, and pdlcount are now volatile.
6054 * bidi.c (bidi_push_it, bidi_pop_it):
6055 * fns.c (copy_hash_table):
6056 * image.c (define_image_type):
6057 * keyboard.c (kbd_buffer_store_event_hold):
6058 * process.c (Fprocess_send_eof):
6059 * xfaces.c (x_create_gc) [HAVE_NS]:
6060 * xgselect.c (xg_select):
6061 Prefer assignment to memcpy when either will do.
6063 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6064 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6065 time an item is removed. No need to mark this function 'inline';
6066 the compiler knows better than we do.
6068 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6070 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6071 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6072 to change_frame_size (Bug#12388).
6073 (windowDidResize:): Pass YES to updateFrameSize.
6075 * nsterm.h: Add delay parameter to updateFrameSize.
6077 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6079 Discard killed buffers from deleted window and frame objects.
6080 This reduces an amount of references to killed buffers and
6081 helps GC to reclaim them faster.
6082 * alloc.c (discard_killed_buffers): New function.
6083 (mark_object): Use it for deleted windows and frames.
6084 (mark_object): If symbol's value is set up for a killed buffer
6085 or deleted frame, restore its global binding.
6086 * data.c (swap_in_global_binding): Add GC notice.
6087 (swap_in_symval_forwarding): Use convenient set_blv_where.
6088 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6089 * window.h: ... to here.
6091 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6093 Convenient macro to check whether the buffer is live.
6094 * buffer.h (BUFFER_LIVE_P): New macro.
6095 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6096 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6098 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6100 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6101 composition cases (Bug#12364).
6103 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6104 overhang of succeeding glyphs overlapping box cursor.
6106 * w32term.c (x_draw_glyph_string): Likewise.
6108 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6110 Simplify, document, and port floating-point (Bug#12381).
6111 The porting part of this patch fixes bugs on non-IEEE platforms
6112 with frexp, ldexp, logb.
6113 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6115 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6116 support, by removing commented-out code and briefly listing the
6117 C89 functions excluded. The commented-out stuff was confusing
6118 maintenance, e.g., we thought we needed cbrt but it was commented out.
6119 (logb): Remove decl; no longer needed.
6120 (isfinite): New macro, if not already supplied.
6121 (isnan): Don't replace any existing macro.
6122 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6123 are present on all C89 platforms.
6124 (Ffrexp): Do not special-case zero, as frexp does the right thing
6126 (Flogb): Do not use logb, as it doesn't have the desired meaning
6127 on hosts that use non-base-2 floating point. Instead, stick with
6128 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6129 frexp, to avoid getting an unspecified result.
6131 * xdisp.c (Qinhibit_debug_on_message): Now static.
6133 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6135 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6136 NSBezierPath (Bug#12131).
6138 2012-09-10 Chong Yidong <cyd@gnu.org>
6140 * fns.c (Fdelq, Fdelete): Doc fix.
6142 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6144 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6145 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6147 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6149 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6150 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6153 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6155 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6156 left fringe if the window has a left margin. This avoids leaving
6157 traces of the cursor because its leftmost pixel is not drawn over.
6159 * dispnew.c (update_window_line): When the left margin area of a
6160 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6161 that screen line. (Bug#12277)
6163 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6165 Assume C89 or later for math functions (Bug#12381).
6166 This simplifies the code, and makes it a bit smaller and faster,
6167 and (most important) makes it easier to clean up signal handling
6168 since we can stop worring about floating-point exceptions in
6169 library code. That was a problem before C89, but the problem
6170 went away many years ago on all practical Emacs targets.
6171 * data.c, image.c, lread.c, print.c:
6172 Don't include <math.h>; no longer needed.
6173 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6174 might be autoconfigured, as that never happens.
6176 * doprnt.c (DBL_MAX_10_EXP):
6177 * print.c (DBL_DIG):
6178 Remove. C89 or later always defines these.
6179 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6180 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6181 (arith_error, domain_error, domain_error2):
6182 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6183 no longer needed -- we simply return what C returns. All uses removed.
6184 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6186 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6187 Remove. All uses expanded, as these macros are no longer used
6188 more than once and are now more trouble than they're worth.
6189 (Ftan): Use tan, not sin / cos.
6190 (Flogb): Assume C89 frexp.
6191 (fmod_float): Assume C89 fmod.
6192 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6193 (init_floatfns): Remove. All uses removed.
6195 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6197 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6198 compositeToPoint for OSX < 10.6 (Bug#12390).
6200 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6202 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6203 This produces more-accurate results.
6205 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6207 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6208 changes (Bug#12088).
6210 2012-09-08 Chong Yidong <cyd@gnu.org>
6212 * syntax.c (Fstring_to_syntax): Doc fix.
6214 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6216 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6217 in the internal border.
6218 (x_set_window_size): Remove static variables and their usage.
6219 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6220 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6221 Remove fringe/internal border adjustment (Bug#11052).
6222 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6223 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6224 (ns_fix_rect_ibw): Remove.
6225 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6226 (ns_dumpglyphs_box_or_relief): Ditto.
6227 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6229 (ns_dumpglyphs_image): Ditto.
6230 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6232 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6233 their usage. Add fringe_extended_p and its use as in other terms.
6234 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6235 scroll bar was removed.
6236 (updateFrameSize): New function.
6237 (windowDidResize): Move code to updateFrameSize and call it.
6239 * nsterm.h (EmacsView): Add updateFrameSize.
6241 2012-09-07 Chong Yidong <cyd@gnu.org>
6243 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6245 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6247 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6249 More signal-handler cleanup (Bug#12327).
6250 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6251 Problem introduced when merging patches. Noted by Eli Zaretskii in
6252 <http://bugs.gnu.org/12327#67>.
6253 * floatfns.c: Comment fix.
6254 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6255 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6256 and anyway the declaration is harmless even if SIGDANGER is not defined.
6257 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6258 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6259 source files not surprisingly expected syssignal.h to define, or
6260 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6261 Include <sys/ioctl.h>, for FIONREAD.
6262 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6263 This eliminates a problem whereby other files mysteriously had
6264 to include "syssignal.h" before including "systty.h" if they
6265 wanted to use "#ifdef SIGIO".
6267 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6269 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6271 * w32.c (sigemptyset): Empty the set.
6272 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6274 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6276 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6278 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6279 (mark_object): Likewise for frame objects.
6281 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6283 * syssignal.h (handle_on_main_thread): Always declare,
6284 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6285 This ports to platforms without HAVE_PTHREAD.
6287 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6289 Signal-handler cleanup (Bug#12327).
6290 Emacs's signal handlers were written in the old 4.2BSD style with
6291 sigblock and sigmask and so forth, and this led to some
6292 inefficiencies and confusion. Rewrite these to use
6293 pthread_sigmask etc. without copying signal sets around. Also,
6294 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6295 'signal', and instead use functions that do not attempt to take
6296 over the system name space. This patch causes Emacs's text
6297 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6298 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6299 Do not include <signal.h> or "syssignal.h", as these
6300 modules do not use signals.
6301 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6302 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6303 Do not include <signal.h>, as "syssignal.h" does that for us now.
6304 * atimer.c (sigmask_atimers): New function.
6305 (block_atimers, unblock_atimers): New functions,
6306 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6308 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6309 no longer needed here.
6310 * emacs.c (main): Inspect existing signal handler with sigaction,
6311 so that there's no need to block and unblock SIGHUP.
6312 * sysdep.c (struct save_signal): New member 'action', replacing
6313 old member 'handler'.
6314 (save_signal_handlers, restore_signal_handlers):
6315 Use sigaction instead of 'signal' to save and restore.
6316 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6317 New function. All users of 'signal' modified to use set_sighandler
6318 if they're writeonly, and to use sys_signal if they're read+write.
6319 (emacs_sigaction_init, forwarded_signal): New functions.
6320 (sys_signal): Remove. All uses replaced by calls to sigaction
6321 and emacs_sigaction_init, or by direct calls to 'signal'.
6322 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6323 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6324 all uses replaced by pthread_sigmask etc. calls.
6325 * syssignal.h: Include <signal.h>.
6326 (emacs_sigaction_init, forwarded_signal): New decls.
6327 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6328 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6329 (sigmask, sys_sigmask): Remove; no longer needed.
6330 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6331 (sigblock, sigunblock, sigfree):
6332 (sigsetmask) [!defined sigsetmask]:
6333 Remove. All uses replaced by pthread_sigmask.
6334 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6335 no longer need to be replaced, and its typical old uses
6336 are now done via emacs_sigaction_init and sigaction.
6337 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6338 (sys_sigdel): Remove; unused.
6339 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6341 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6343 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6344 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6346 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6348 Explicitly mark buffer_defaults and buffer_local_symbols.
6349 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6350 mark_local_symbols here.
6351 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6352 since special buffers aren't marked here any more.
6353 (allocate_buffer): Chain new buffer with all_buffers here...
6354 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6356 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6357 (syms_of_buffer): Remove staticpro of the above.
6358 (init_buffer_once): Set names for buffer_defaults and
6359 buffer_local_symbols.
6361 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6363 Use bool for booleans in font-related modules.
6364 * font.c (font_intern_prop, font_style_to_value)
6365 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6366 (generate_otf_features, font_check_otf_features, font_check_otf)
6367 (font_match_p, font_list_entities, font_at):
6368 * fontset.c (fontset_id_valid_p, reorder_font_vector
6369 (fontset_find_font, Fset_fontset_font)
6370 (face_suitable_for_char_p) [0]:
6371 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6372 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6373 (m17n_flt_initialized, ftfont_shape_by_flt):
6374 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6375 * nsfont.m (nsfont_draw):
6376 * w32font.c (w32font_draw):
6377 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6378 Use bool for booleans.
6379 * font.h: Adjust to above API changes.
6380 (struct font, struct font_driver, struct font_driver_list):
6381 Use bool for booleans.
6382 (struct font): Remove useless member encoding_type.
6384 * fontset.c, xftfont.c: Omit unnecessary static decls.
6386 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6388 * alloc.c (mark_object): Revert window marking code
6389 since it's unsafe for the Fset_window_configuration.
6391 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6393 Fix race conditions with signal handlers and errno (Bug#12327).
6394 Be more systematic about preserving errno whenever a signal
6395 handler returns, even if it's not in the main thread. Do this by
6396 renaming signal handlers to distinguish between signal delivery
6397 and signal handling. All uses changed.
6398 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6399 * data.c (deliver_arith_signal): Rename from arith_error.
6400 * dispnew.c (deliver_window_change_signal): Rename from
6401 window_change_signal.
6402 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6403 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6404 * keyboard.c (deliver_input_available_signal): Rename from
6405 input_available_signal.
6406 (deliver_user_signal): Rename from handle_user_signal.
6407 (deliver_interrupt_signal): Rename from interrupt_signal.
6408 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6409 (deliver_child_signal): Rename from sigchld_handler.
6410 * atimer.c (handle_alarm_signal):
6411 * data.c (handle_arith_signal):
6412 * dispnew.c (handle_window_change_signal):
6413 * emacs.c (handle_fatal_signal, handle_danger_signal):
6414 * keyboard.c (handle_input_available_signal):
6415 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6416 * process.c (handle_pipe_signal, handle_child_signal):
6417 New functions, with the actual signal-handling code taken from the
6418 original respective signal handlers, sans the sporadic attempts to
6419 preserve errno, since that's now done by handle_on_main_thread.
6420 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6421 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6422 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6424 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6425 Move initialization of main_thread to sysdep.c's init_signals.
6426 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6427 our usage, and simplifies the mainline code.
6428 (record_child_status_change): New static function, as a helper
6429 for handle_child_signal, and with most of the old child handler's
6431 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6432 (handle_child_signal): Use the above.
6433 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6434 Moved here from emacs.c.
6435 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6436 code moved here from emacs.c's main function.
6437 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6438 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6439 This lets callers save and restore errno properly.
6441 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6443 Remove redundant or unused things here and there.
6444 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6445 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6446 * editfns.c (Fcompare_buffer_substrings): Likewise.
6447 * frame.h (struct terminal, struct font_driver_list):
6448 Remove redundant declarations.
6449 * window.h (Qleft, Qright): Likewise.
6451 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6453 Do not mark objects from deleted buffers, windows and frames.
6454 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6455 (mark_object): Likewise for windows and frames.
6457 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6459 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6460 buffer_defaults and buffer_local_symbols as valid objects.
6461 Return special value to denote them.
6463 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6465 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6466 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6467 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6468 (file_name_absolute_p, Fsubstitute_in_file_name):
6469 (check_executable, check_writable, Ffile_accessible_directory_p)
6470 (Fset_file_selinux_context, Fdefault_file_modes)
6471 (Finsert_file_contents, choose_write_coding_system)
6472 (Fwrite_region, build_annotations, a_write, e_write)
6474 * filelock.c (boot_time_initialized, get_boot_time)
6475 (get_boot_time_1, lock_file_1, within_one_second):
6476 * floatfns.c (in_float):
6477 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6478 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6479 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6480 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6481 * window.c (compare_window_configurations):
6482 Use bool for booleans.
6483 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6484 (Fdefault_file_modes): Now mode_t, not int, for modes.
6485 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6486 (internal_delete_file): Now returns void, not a (boolean) int,
6487 since nobody was looking at the return value.
6488 * lisp.h, window.h: Adjust to above API changes.
6490 * xdisp.c (set_message): Simplify and reindent last change.
6492 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6494 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6496 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6498 * eval.c (call_debugger): Make the function non-static so that we
6499 can call it from set_message.
6501 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6502 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6504 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6506 Give more-useful info on a fatal error (Bug#12328).
6507 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6508 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6509 of doing the work ourselves.
6510 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6511 do most of the work.
6512 (fatal_error_backtrace): New function, taken from the guts
6513 of the old fatal_error_signal, but with a new option to output
6515 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6516 info about the signal than just its number.
6517 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6518 * sysdep.c: Include <execinfo.h>
6519 (emacs_backtrace): New function, taken partly from the previous
6520 code of the 'die' function.
6521 (emacs_abort): Call fatal_error_backtrace rather than abort.
6523 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6525 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6526 eager (load-time) macro-expansion.
6527 * lisp.mk (lisp): Add macroexp.
6529 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6531 Simplify redefinition of 'abort' (Bug#12316).
6532 Do not try to redefine the 'abort' function. Instead, redo
6533 the code so that it calls 'emacs_abort' rather than 'abort'.
6534 This removes the need for the NO_ABORT configure-time macro
6535 and makes it easier to change the abort code to do a backtrace.
6536 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6537 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6538 Remove; sysdep.c's emacs_abort now takes its place.
6539 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6540 'abort' changed to use 'emacs_abort'.
6541 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6542 (abort) [!defined abort]: Rename to ...
6543 (emacs_abort): ... new name.
6544 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6545 the place of the old 'abort' in emacs.c.
6546 * w32.c, w32fns.c (abort): Do not #undef.
6547 * w32.c (emacs_abort): Rename from w32_abort.
6549 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6551 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6552 offsets[j].dv, since the y axis of the screen coordinates points
6553 down, while the y axis of the font definition coordinates points
6554 up. This fixes display of Arabic diacritics such as KASRA and
6555 KASRATAN. (Bug#11860)
6557 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6559 Be more systematic about _setjmp vs setjmp.
6560 * alloc.c (test_setjmp, mark_stack):
6561 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6562 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6563 (png_load, my_error_exit, jpeg_load):
6564 * process.c (send_process_trap, send_process):
6565 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6566 The underscored versions are up to 30x faster on some hosts.
6567 Formerly, the code used setjmp+longjmp sometimes and
6568 _setjmp+_longjmp at other times, with no particular reason to
6569 prefer setjmp+longjmp.
6571 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6573 Fix minor problem found by static checking.
6574 * buffer.c (Fdelete_all_overlays): Return nil.
6576 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6578 * buffer.c (Fdelete_all_overlays): New function.
6580 2012-09-03 Chong Yidong <cyd@gnu.org>
6582 * gtkutil.c: Add extern decl for Qxft.
6584 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6586 * emacs.c, eval.c: Use bool for boolean.
6587 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6588 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6589 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

6595 * process.c (read_process_output, exec_sentinel):
6596 Use bool for booleans.
6597 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6598 All callers changed.
6599 * eval.c (interactive_p): Omit always-true boolean argument
6600 EXCLUDE_SUBRS_P. All callers changed.
6601 * dispextern.h, lisp.h: Reflect above API changes.
6602 * firstfile.c (dummy): Use the address of 'main', whose signature
6603 won't change, instead of the address of 'initialize', whose
6604 signature just changed from int to bool.
6605 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6606 * msdos.c (fatal_error_in_progress): ... from here.
6607 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6609 (redisplay_internal, unwind_redisplay): Simply clear
6610 REDISPLAYING_P when unwinding, instead of saving its previous,
6611 always-false value and then restoring it.
6613 Clean up some extern decls.
6614 Mostly, this hoists extern decls out of .c files and into .h files.
6615 That way, we're more likely to catch errors if the interfaces change.
6616 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6617 declare xg_mark_data.
6618 * dispextern.h (x_frame_parm_handlers):
6620 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6621 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6622 (Qultra_bold, Qoblique, Qitalic):
6623 Move extern decl here from .c file.
6624 * alloc.c (xg_mark_data) [USE_GTK]:

6633 * process.c (QCfamily, QCfilter):
6634 * widget.c (free_frame_faces):
6635 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6636 * xfont.c (x_clear_errors):
6637 * xterm.c (x_frame_parm_handlers):
6638 Remove now-redundant extern decls.
6639 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6640 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6642 * xfaces.c: Remove unnecessary static decls.
6643 * xterm.c (updating_frame): Remove decl of nonexistent object.
6645 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6646 when building globals.h, as the objects that are not built on
6647 this host are not needed to compile C files on this host.
6649 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6651 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6659 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6660 (Fsubstitute_command_keys):

6664 (format_time_string, general_insert_function)
6665 (make_buffer_string, make_buffer_string_both)
6666 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
6667 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

6678 (set_intervals_multibyte_1, set_intervals_multibyte):
6679 * keyboard.c (decode_timer):
6680 Use bool for boolean.
6681 * intervals.h, lisp.h, systime.h: Reflect above API changes.

6684 2012-09-02 Chong Yidong <cyd@gnu.org>
6686 * keymap.c (push_key_description): Print M-TAB as C-M-i
6689 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6691 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6692 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

6697 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
6699 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6701 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6702 more than one grapheme cluster passed to the shaper: compute the
6703 offset adjustment values separately for each cluster. (Bug#11860)
6705 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6706 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6707 about implicit conversions from integer to pointer.
6709 2012-09-01 Daniel Colascione <dancol@dancol.org>
6711 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6712 system used too early.
6714 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6716 Better seed support for (random).
6717 * emacs.c (main): Call init_random.

6740 directly accessing frame internals.
6742 * w32font.h: Include font.h. Define syms_of_w32font and
6745 * process.c: Include TERM_HEADER instead of listing all possible
6746 window-system headers.
6748 * nsterm.h: Remove declarations now in frame.h.
6749 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
6751 * menu.c: Include TERM_HEADER instead of listing all possible
6752 window-system headers.
6754 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6757 * keyboard.c: Include TERM_HEADER instead of listing all possible
6758 window-system headers.
6760 * image.c: Include TERM_HEADER instead of listing all possible
6761 window-system headers. Declare Vlibrary_cache when compiling for
6764 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6765 window system declarations.
6767 * frame.h: Move common functions here: set_frame_menubar,
6768 x_set_window_size, x_sync, x_get_focus_frame,
6769 x_set_mouse_position, x_set_mouse_pixel_position,
6770 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
6771 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

6791 the current window system; include in list of objects to link into
6794 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6796 Remove mark_ttys function and fix tty_display_info initialization.
6797 * lisp.h (mark_ttys): Remove prototype.
6798 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6799 to mark_ttys because all possible values of 'top_frame' slot are
6800 the frames which are reachable from Vframe_list.
6801 * term.c (mark_ttys): Remove.
6802 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6804 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6806 Change struct frame bitfields from unsigned char to unsigned.
6807 * frame.h (struct frame): Change type of 'display_preempted',
6808 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
6809 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6810 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6811 bitfields from unsigned char to unsigned.
6813 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6815 Remove unused member of struct x_output and struct w32_output.
6816 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.

6819 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
6821 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
6822 does not become zero (Bug#12234).
6824 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6826 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6827 for GCC 4.7.1 x86-64.
6829 2012-08-30 Glenn Morris <rgm@gnu.org>
6831 * lread.c (init_lread): For out-of-tree builds, only add the
6832 source directory's site-lisp dir to the load-path if it exists,
6833 consistent with in-tree builds. (Bug#12302)
6835 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6837 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
6838 button_values to NULL. Call setStykeMask so dialogs get a close button.
6839 (windowShouldClose:): Set window_closed.
6840 (dealloc): New member, free button_values.
6841 (process_dialog:): Make member function. Remove window argument,
6842 replace window with self. Count buttons and allocate and store values
6844 (addButton:value:row:): value is int with the name tag. Call setTag
6845 with tag. Remove return self, declare return value as void.

6850 (initFromContents:isQuestion:): Adjust call to process_dialog.
6851 Code formatting change.
6852 (timeout_handler:): Set timer_fired to YES.
6853 (runDialogAt:): Set timer_fired to NO.
6854 Handle click on close button as quit.
6856 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6857 Add window_closed and button_values. Add void as return value for
6858 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6859 Add process_dialog as new member.
6861 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6863 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6864 is not one of the heaps we manage. (Bug#12242)
6866 2012-08-28 Glenn Morris <rgm@gnu.org>
6868 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

6879 * buffer.c (Fset_buffer_major_mode): Signal an error
6880 if the buffer is dead.
6881 (Fother_buffer, other_buffer_safely): Remove redundant
6884 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
6886 Always use set_buffer_if_live to restore original buffer at unwind.
6887 * buffer.h (record_unwind_current_buffer): New function.
6888 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:

6890 * undo.c, window.c: Adjust users.
6891 * buffer.c (set_buffer_if_live): Fix comment.
6893 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
6895 Fix usage of set_buffer_internal.
6896 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
6897 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
6898 * coding.c (decode_coding): Omit redundant test.
6899 * fileio.c (decide_coding_unwind): Likewise.
6900 * fns.c (secure_hash): Likewise.

6902 * keyboard.c (command_loop_1): Likewise.
6903 * print.c (PRINTFINISH): Likewise.
6904 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
6906 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

6926 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6927 and remove last int (actually boolean) argument, which was always 0.
6928 All callers changed.
6929 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6930 * dispextern.h (struct composition_it): Use bool for boolean.
6931 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6932 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6933 * dired.c (file_name_completion):
6934 Use bool for boolean. (This was missed in an earlier change.)
6936 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6938 * window.c (Fset_window_configuration): Revert first part of
6941 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6943 * nsterm.h (NSPanel): New class variable dialog_return.
6945 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6946 Initialize dialog_return.
6947 (windowShouldClose:): Use stop instead of stopModalWithCode.
6948 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6949 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6951 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

6996 Use bool for booleans.
6997 * coding.h, lisp.h: Reflect above API changes.
6998 * coding.c: Remove unnecessary static function decls.
6999 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7000 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7001 not a boolean 'int', since callers never look at the return value.
7002 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7003 * coding.h (decoding_buffer_size, encoding_buffer_size)
7004 (emacs_mule_string_char): Remove unused extern decls.
7005 (struct iso_2022_spec, struct coding_system):
7006 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7007 (struct emacs_mule_spec): Remove unused field 'full_support'.
7008 All initializations removed.
7009 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7011 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7013 Fix spare memory change (Bug#12286).
7014 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7015 (valid_lisp_object_p): Likewise.
7017 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7019 * window.c (Fset_window_configuration): Record any window's old
7020 buffer if it's replaced (see Bug#8789). If the new current
7021 buffer doesn't appear in the selected window, go to its old
7024 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7026 Special MEM_TYPE_SPARE to denote reserved memory.
7027 * alloc.c (enum mem_type): New memory type.
7028 (refill_memory_reserve): Use new type for spare memory.
7029 This prevents live_cons_p and live_string_p from incorrect
7030 detection of uninitialized objects from spare memory as live.
7032 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7035 * Makefile.in (.PHONY): versioclean -> versionclean.
7037 Remove unused external symbols.
7038 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7039 * window.c (Qwindow_valid_p, decode_valid_window):
7040 Now static, not extern.
7041 * data.c (Qinterval): Remove; unused.
7042 (syms_of_data): Do not define 'interval'.
7043 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7044 * window.h (decode_valid_window):
7047 * character.c, charset.c, chartab.c: Use bool for booleans.

7058 (map_sub_char_table):
7059 Use bool for boolean.
7060 * character.c (str_to_unibyte): Omit last boolean argument; it was
7061 always 0. All callers changed.
7062 * character.h, charset.h: Adjust to match previous changes.
7063 * character.h (char_printable_p): Remove decl of nonexistent function.
7064 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7065 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7066 are all boolean, so make them single-bit bitfields.
7068 * lisp.h (ASET): Remove attempt to detect side effects.
7069 It was meant to be temporary and it often doesn't work,
7070 because when IDX has side effects the behavior of IDX==IDX
7071 is undefined. See Stefan Monnier in
7072 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7074 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7076 * lisp.h (functionp): New function (extracted from Ffunctionp).
7077 (FUNCTIONP): Use it.
7078 * eval.c (Ffunctionp): Use it.
7080 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7082 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7083 as that's faster and simpler than static storage. Don't bother
7084 with the g_main_context_query overhead if g_main_context_pending
7085 says no events are pending.
7086 (gfds, gfds_size): Remove these static vars.
7087 (xgselect_initialize): Remove; no longer needed.
7088 All uses and decls removed.
7090 * emacs.c (fatal_error_signal_hook): Remove.
7091 All uses removed. This leftover from old code was always 0.
7093 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7094 * casefiddle.c (casify_object, casify_region):
7095 * casetab.c (set_case_table):
7096 * category.c, category.h (word_boundary_p):
7097 * category.h (CHAR_HAS_CATEGORY):
7098 Use bool for booleans, instead of int.
7100 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7102 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7104 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7106 On assertion failure, print backtrace if available.
7107 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7108 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7109 * Makefile.in (LIB_EXECINFO): New macro.
7112 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7113 * bytecode.c (exec_byte_code):
7114 * callint.c (check_mark, Fcall_interactively):
7115 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7116 (getenv_internal, sync_process_alive, call_process_exited):
7117 * lisp.h (USE_SAFE_ALLOCA):
7118 Use bool for booleans, instead of int.
7119 * lisp.h, process.h: Adjust prototypes to match above changes.
7120 * callint.c (Fcall_interactively): Don't assume the mark's
7121 offset fits in 'int'.
7123 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7125 * buffer.c, buffer.h: Use bool for boolean.
7126 * buffer.c (reset_buffer_local_variables)

7132 (mmap_enlarge, mmap_set_vars):
7133 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7134 Use bool for booleans, instead of int.
7135 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7136 since the 1-or-0 return value is always ignored anyway.
7137 (mmap_initialized_p):
7138 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7139 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7141 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7143 * bidi.c: Use bool for boolean.
7144 This is a bit more readable, and makes the text segment of bidi.o
7145 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7146 Presumably it's faster too.
7147 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7149 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7150 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

7152 (bidi_explicit_dir_char, bidi_level_of_next_char)
7153 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7154 Use bool for booleans, instead of int.
7155 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7156 (bidi_unshelve_cache): Adjust decls to match code.
7158 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7160 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7163 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7165 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7166 * atimer.h: Include <stdbool.h>.
7168 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7170 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7171 compile time tests instead of run time tests on systems that do
7173 (FRAME_MAC_P): Remove leftover from deleted code.
7174 * frame.c (syms_of_frame): Remove leftover from deleted code.
7176 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7178 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7180 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7182 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7183 Otherwise, the compiler complains about (A?B:C) where B is void
7184 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7185 (fontset_add): Return void, for FONTSET_ADD.
7187 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7189 * alloc.c: Use bool for booleans.
7190 (gc_in_progress, abort_on_gc)
7191 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7192 (dont_register_blocks) [GC_MALLOC_CHECK]:
7193 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7194 (check_string_bytes, make_specified_string, memory_full)
7195 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7196 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7197 (mark_stack, valid_pointer_p, make_pure_string)
7198 (Fgarbage_collect, survives_gc_p, gc_sweep):
7199 Use bool for booleans, instead of int.
7200 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7201 Remove unused local.
7202 * alloc.c (PURE_POINTER_P):
7203 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7204 * editfns.c (Fformat):
7205 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7207 * fns.c (sweep_weak_table):
7208 * lisp.h (suppress_checking, push_message, survives_gc_p)
7209 (make_pure_string, gc_in_progress, abort_on_gc):
7210 * lread.c (readchar, read1):
7211 * print.c (Fprin1_to_string):
7212 * xdisp.c (push_message):
7213 Use bool for booleans affected directly or indirectly by
7216 Make recently-introduced setters macros.
7217 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7218 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7219 (set_fontset_default, set_fontset_fallback): Rename from their
7220 upper-case counterparts, and make them functions rather than macros.
7221 This is more consistent with the other recently-introduced setters.
7222 These don't need to be inline, since they're local.
7224 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7226 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7227 the loop (Bug#12247).
7229 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7231 * lisp.h (vcopy): Use memcpy rather than our own loop.
7232 This fixes a performance regression introduced by the recent
7233 addition of vcopy. This means 'vcopy' will need to be modified
7234 for a copying collector, but that's OK. Also, tighten the
7235 checking in the assertion.
7237 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7239 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7240 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7241 non-base glyph for the width of the base character, according to
7242 what x_draw_composite_glyph_string_foreground expects.
7243 Generate WADJUST value according to composition_gstring_width's
7244 expectations, to produce correct width of the composed character.
7245 Reverse the sign of the DU offset produced by ScriptPlace.
7247 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7249 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7251 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7253 Avoid direct writes to contents member of struct Lisp_Vector.
7254 * lisp.h (vcopy): New function to copy data into vector.
7255 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7256 * fns.c (Ffillarray): Use ASET.
7257 * keyboard.c (timer_check_2): Use AREF and ASET.
7258 (append_tool_bar_item, Frecent_keys): Use vcopy.
7259 * lread.c (read_vector): Use ASET.
7260 * msdos.c (Frecent_doskeys): Use vcopy.
7261 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7262 (Finternal_merge_in_global_face): Use ASET and vcopy.
7263 * xfont.c (xfont_list_pattern): Likewise.
7265 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7267 * window.c (Fwindow_point): For the selected window always return
7268 the position of its buffer's point.
7269 (Fset_window_point): For the selected window always go in its
7270 buffer to the specified position.
7272 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7274 Setter macros for fontsets.
7275 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7276 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7277 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7280 2012-08-20 Glenn Morris <rgm@gnu.org>
7282 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7283 Don't assume that `ln -f' works.
7285 2012-08-20 Eli Zaretskii <eliz@gnu.org>

7313 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7314 (set_hash_hash, set_hash_index): Rename with _slot suffix.

7329 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7331 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7333 Rely on <config.h> + <unistd.h> to declare 'environ',
7334 as gnulib does this if the system doesn't.
7335 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7336 Remove declaration. MS-Windows declares it on stdlib.h which is

7339 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

7370 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7371 Return void, not Lisp_Object. Otherwise, the compiler
7372 complains about (A?B:C) where B is void and C is Lisp_Object

7374 the API of sub_char_table_set_contents.

8206 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8207 * w32.c (init_environment): Change the default values of many
8208 environment variables in dflt_envvars[] to NULL, to avoid pushing
8209 them into environment when they were not already defined.
8210 Remove the code that deletes site-lisp subdirectories from the default
8211 value of EMACSLOADPATH, as it is no longer needed.
8212 (check_windows_init_file): Now external, not static.
8213 Use Vload_path as is, without adding anything, as this function is now
8214 called when Vload_path is already set up.
8216 * w32.h (check_windows_init_file): Add prototype.
8218 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8219 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8220 compatibility with Posix platforms.
8221 (main): Move the call to check_windows_init_file to here from
8223 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8224 any, in the DEFALT argument into the root of the Emacs build or
8225 installation tree, as appropriate.
8227 * callproc.c (init_callproc_1): Call decode_env_path instead of
8228 doing its equivalent by hand.
8229 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8230 the code that sets Vexec_path run on MS-Windows.
8232 * lread.c (init_lread): Add comments to #ifdef's.
8234 * msdos.c (dos_set_window_size, IT_update_begin)
8235 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
8236 instead of direct references.

8242 Now constants, not macros.
8244 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8246 Remove unnecessary casts involving pointers.
8247 These casts are no longer needed now that we assume C89 or later,
8248 since they involve casting to or from void *.
8249 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8250 (make_pure_float, make_pure_vector):
8251 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8260 (x_get_window_property, x_get_window_property_as_lisp_data):
8261 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8262 Remove unnecessary pointer casts.
8263 * alloc.c (record_xmalloc): New function.
8264 * lisp.h (record_xmalloc): New decl.
8265 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8266 more like a function. This is because the pointer cast is not
8267 needed. All uses changed.
8268 * print.c (print_string, print_error_message): Avoid length recalc.
8270 Improve fix for macroexp crash with debugging (Bug#12118).
8271 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8272 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8273 not supposed to be invoked from the garbage collector.
8274 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8275 (gc_aset): New function, which is like ASET but can be
8276 used in the garbage collector.
8277 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8287 <g_b_init_create_symbolic_link>: New static flags.
8288 (globals_of_w32): Initialize them to zero.
8289 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8290 (map_w32_filename): Improve commentary. Simplify switch.
8291 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8292 headers (most versions of MinGW w32api don't).
8293 (get_security_info, create_symbolic_link)
8294 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8296 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8297 in the argument file name.

8300 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8301 have the required privileges.
8302 (get_file_security_desc_by_name): Rename from
8303 get_file_security_desc.
8304 (stat_worker): New function, with most of the guts of 'stat', and
8305 with addition of handling of symlinks and support for 'lstat'.
8306 If possible, get file's attributes and security information by
8307 handle, not by name. Produce S_IFLNK bit for symlinks, when
8308 called from 'lstat'.
8309 (stat, lstat): New functions, call 'stat_worker'.
8310 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8311 symlinks when the underlying filesystem supports them.
8313 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8315 Fix macroexp crash on Windows with debugging (Bug#12118).
8316 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8317 checking subscripts; problem introduced with the recent
8318 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8319 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8320 since it's used in non-static inline functions now.
8322 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8323 Don't assume buffer size fits in 'int'. Remove unused local.

8340 * category.c (CATEGORY_INLINE):
8341 * character.c (CHARACTER_INLINE):
8342 * charset.c (CHARSET_INLINE):
8343 * composite.c (COMPOSITE_INLINE):
8344 * dispnew.c (DISPEXTERN_INLINE):
8345 * sysdep.c (SYSTIME_INLINE):
8346 Define to EXTERN_INLINE, so that the corresponding functions
8347 are compiled into code.
8348 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8349 (INLINE_HEADER_END): New macros.
8350 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8372 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8374 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8375 This how ASET and AREF are supposed to work, and makes
8376 it easier to think about future improvements. See
8377 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8378 * charset.h (set_charset_attr): New function.

8632 does that unconditionally. Remove file, which is now empty.
8634 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
8637 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

8652 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
8653 Move to after the definition of struct Lisp_Char_Table,
8654 since the former now needs that type defined.

8755 * w32inevt.c: Include w32inevt.h.
8756 (w32_read_console_input): New inline function, calls either
8757 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
8758 w32_console_unicode_input.
8759 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8760 (w32_kbd_patch_key, key_event): Use the codepage returned by
8761 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
8762 (key_event): use uChar.UnicodeChar only if

8793 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8794 enumeration constants, as PURE and HEAP are too general, and clash
8795 with other headers and sources, such as gmalloc.c and the
8796 MS-Windows system headers. All users changed.
8798 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8800 Revert last save_excursion_save and save_excursion_restore changes.
8801 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8811 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8813 Improve GDB symbol export (Bug#12036).
8814 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8815 arms of an 'if', not using conditional expressions; otherwise GDB
8816 complains about the types in the unevaluated arm when the argument
8817 is an integer literal.
8818 (xgetint): Simplify expression.
8819 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8820 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8821 Zaretskii in <http://bugs.gnu.org/12036#13>.
8822 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8823 needed now that we have gdb_make_enums_visible.
8824 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8825 (enum enum_USE_LSB_TAG):
8826 New enum types, packaging up enums that need to be exported to GDB.

8845 * xfns.c (syms_of_xfns): Likewise.
8847 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

8850 * lisp.h (struct Lisp_Excursion): New data type.
8851 (PVEC_EXCURSION): New pseudovector type.
8852 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8853 to deal with it. Adjust comments.

8864 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8866 Fix export of symbols to GDB (Bug#12036).
8867 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8868 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8869 emacs.c, as this is a more-suitable home. Had this been done earlier
8870 the fix for 12036 would have avoided some of the problems noted in
8871 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8872 would have been more obvious.
8873 * emacs.c: Do not include <verify.h>; no longer needed.
8874 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8875 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8876 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8882 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8883 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8884 not be usable in #if. This simplifies things.
8886 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8888 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8890 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

8893 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8894 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8895 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8896 Adjust to changes in lisp.h and emacs.c, by using
8897 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8898 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8899 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8900 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8901 instead of gdb_valbits.
8902 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8903 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8904 instead of gdb_array_mark_flag.
8905 (xboolvector): Get size from $->size, not $->header.size.
8906 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8907 (xreload, hook-run, hookpost-run): Remove.
8908 * emacs.c: Include <verify.h>.
8909 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8910 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8912 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8913 (gdb_USE_LSB_TAG): New enum constants.
8914 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8915 Also define these as enum constants, so they're visible to GDB.
8916 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8917 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8918 as constants, so they're visible to GDB.
8919 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8920 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8921 Now enum constants, not macros, so they're visible to GDB.
8922 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8923 more convenient now. All uses changed.
8924 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8925 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8927 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8932 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8934 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8935 add argument, tune behavior, and adjust all callers.
8937 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8939 Use typedef for EMACS_INT, EMACS_UINT.
8940 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8941 than macros. This simplifies debugging in the usual case, since
8942 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8943 and it allows expressions involving EMACS_INT casts.
8944 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8946 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8956 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8958 Adjust buffer text indirection counters at the end of Fkill_buffer.
8959 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8960 buffer is definitely dead. This should really fix an issue reported
8961 by Christoph Scholtes again. (Bug#12007).
8962 (init_buffer_once): Initialize indirection counters of
8963 buffer_defaults and buffer_local_symbols (for sanity and safety).
8965 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8967 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8968 and continuation glyphs on tooltip frames, leave them at zero.
8969 Avoids continued lines in tooltips. (Bug#11832)
8971 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8973 Simplify copy_overlay.
8974 * buffer.c (copy_overlay): Simplify. Use build_marker.

8980 or invalid. (Bug#12025)
8982 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
8983 it signals an error when a tooltip frame is being created.
8985 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8987 Cleanup miscellaneous objects allocation and initialization.

8989 specify the subtype. Adjust comment and users.
8990 (build_overlay): New function.
8991 * buffer.c (copy_overlays, Fmake_overlay): Use it.
8992 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
8993 (allocate_misc): Remove prototype.
8994 (build_overlay): Add prototype.
8996 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8998 Swap buffer text indirection counters in Fbuffer_swap_text.
8999 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9000 This avoids crash reported by Christoph Scholtes at
9001 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9003 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9005 * nsmenu.m (Popdown_data): New struct.
9006 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9008 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9009 (initWithContentRect): Make imgView and contentView non-static
9010 and autorelease them. Also autorelease img and matrix (Bug#12005).
9011 (dealloc): Remove (Bug#12005).
9013 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9015 Adjust consing_since_gc when objects are explicitly freed.
9016 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
9017 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
9018 (free_cons, free_misc): Subtract object size from consing_since_gc.
9020 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

9024 (live_buffer, set_marker_internal): New function.
9025 (Fset_marker, set_marker_restricted): Use set_marker_internal.
9026 (set_marker_both, set_marker_restricted_both): Use live_buffer.
9028 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9030 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9031 as it's limited by the amount of memory, not by INT_MAX.
9033 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9035 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9036 in special-event-map. See the discussion at

9759 * s/aix4-2.h (unix): Remove; no longer needed.
9761 EMACS_TIME simplification (Bug#11875).
9762 This replaces macros (which typically do not work in GDB)

9764 The functional style also makes code easier to read and maintain.
9765 * systime.h: Include <sys/time.h> on all hosts, not just if
9766 WINDOWSNT, since 'struct timeval' is needed in general.

9782 (add_emacs_time, sub_emacs_time): New functions.
9783 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9806 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9807 Prefer snprintf to strncpy.
9808 * nsterm.m (ns_term_init):
9809 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9810 * nsterm.m (ns_term_init):
9811 Avoid the need for strncpy, by using build_string or
9812 make_unibyte_string directly. Use dtoastr, not snprintf.
9813 * process.c (Fmake_network_process): Diagnose service names that
9814 are too long, rather than silently truncating them or creating
9815 non-null-terminated names.
9816 (Fnetwork_interface_info): Likewise, for interface names.
9817 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9818 Prefer sprintf to strncat.

9832 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9833 where argument type is known to be a Lisp_Cons.

9850 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9851 argument, adjust users accordingly. Use build_pure_c_string where

9888 O_RDONLY already includes it).
9890 Stop ns builds setting the EMACSLOADPATH environment variable.
9891 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9892 Now it does not set EMACSLOADPATH, just returns the load-path string.
9893 * nsterm.h: Update accordingly.
9894 * lread.c [HAVE_NS]: Include nsterm.h.
9895 (init_lread) [HAVE_NS]: Use ns_load_path.

9905 (ns_init_paths): Do not set EMACSPATH.
9906 * nsterm.h (ns_exec_path): Add it.

9961 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
9963 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9965 Move marker debugging code under MARKER_DEBUG.
9966 * marker.c (MARKER_DEBUG): Move marker debugging code under
9967 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9968 for bootstrap with --enable-checking (~3x slowdown reported
9969 by Juanma Barranquero <lekktu@gmail.com>).
9970 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9972 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9974 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9975 See <http://bugs.gnu.org/11825#29>.
9977 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9979 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9980 has no font, use the frame's font. (Bug#11813)
9981 (display_line): Add commentary about displaying truncation glyphs
9983 (produce_special_glyphs): Move here from term.c.
9985 * term.c (produce_special_glyphs): Move to xdisp.c.
9987 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9990 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9992 * xdisp.c (display_line): Avoid warning about implicit declaration
9995 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9997 * lisp.h: Remove empty conditional.
9999 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10001 * lread.c (load_path_check): Now static.
10003 Fix some minor --with-ns problems found by static checking.
10004 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10005 (x_set_font) [!HAVE_X_WINDOWS]:
10006 * image.c (xpm_load_image) [HAVE_NS]:
10007 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10008 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10009 Remove unused local.
10010 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10011 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10012 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10013 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10014 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10015 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10016 Fix pointer signedness problem.
10017 * xfaces.c (FRAME_X_FONT_TABLE):
10018 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10020 2012-07-07 Glenn Morris <rgm@gnu.org>
10022 * lread.c (load_path_check): New function, split from init_lread.
10023 (init_lread): Reorganize. Motivation:
10024 If EMACSLOADPATH is set, check/warn about that rather than the
10025 defaults, which we are not going to use. Hence we can remove
10026 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10027 Don't warn if site-lisp directories are missing.
10028 If not installed, start from a blank load-path, since
10029 PATH_LOADSEARCH refers to the eventual installation directories.
10031 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10033 Support truncation and continuation glyphs on GUI frames, when
10034 fringes are disabled. (Bug#11832)
10035 * xdisp.c (init_iterator): Get dimensions of truncation and
10036 continuation glyphs even if on GUI frames.
10037 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10038 or both, are absent.
10039 (start_display, move_it_in_display_line_to): Handle the case of a
10040 GUI frame without a fringe to display continuation or truncation
10042 (insert_left_trunc_glyphs): Support GUI frames: make sure
10043 truncation glyphs overwrite enough glyphs from the current line to
10044 have sufficient space in pixels.
10045 (display_line): Support truncation and continuation glyphs on GUI
10046 frames. If some spare pixels are left on the line after inserting
10047 the truncation glyphs, fill that space with a stretch glyph of a
10048 suitably computed width.
10050 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10051 produce_glyphs, to support GUI sessions.
10053 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10055 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10057 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10059 Do not require float-time's arg to fit in time_t (Bug#11825).
10060 This works better on hosts where time_t is unsigned, and where
10061 float-time is applied to the (negative) difference between two times.
10062 * editfns.c (decode_time_components): Last arg is now double *,
10063 not int *, and means to store all the result as a double, without
10064 worrying about whether the seconds part fits in time_t.
10065 All callers changed.
10066 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10067 All callers changed.
10068 (Ffloat_time): Do not fail merely because the specified time falls
10069 outside of time_t range.
10071 2012-07-07 Glenn Morris <rgm@gnu.org>
10073 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10074 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10075 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10077 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10079 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10080 Update dependencies.

10088 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10089 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10090 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10091 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10093 * xfont.c (compare_font_names): Redo to omit the need for casts.
10095 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10097 * xfns.c (Fx_change_window_property): Doc fix.
10098 * w32fns.c (Fx_change_window_property): Doc fix.
10100 * w32fns.c (Fx_window_property): Accept the same arguments as the
10101 X Windows version. Doc fix.
10102 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10104 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10105 Eli Zaretskii <eliz@gnu.org>
10107 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10108 Windows-specific code from nt/config.nt moved here.
10109 Obsolete settings removed.
10111 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10113 * process.c: Avoid unnecessary calls to gettime.
10114 (wait_reading_process_output): Don't get the time of day
10115 when gobbling data immediately and not waiting, as there's no need
10116 for it in that case. This removes a FIXME.
10118 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10120 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10121 is defined (Bug#11768).
10123 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10125 Fix marker debugging code.

10127 if buffer is not multibyte.
10128 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10129 Call byte_char_debug_check with correct arguments.
10131 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10133 Compile marker debugging code only if ENABLE_CHECKING is defined.
10134 * marker.c (byte_char_debug_check, count_markers):
10135 Use only if ENABLE_CHECKING is defined.
10136 (byte_debug_flag): Remove.
10137 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10138 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10140 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10142 Avoid code repetition in marker-related functions.
10143 * marker.c (attach_marker): New function.

10147 Consistently rename charno to charpos.
10148 (marker_position): Add eassert.
10149 (marker_byte_position): Convert to eassert.

10165 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10166 (save_restriction_save): Use build_marker.
10167 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10168 * window.c (save_window_save): Likewise.
10170 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10172 Do not use Fdelete_overlay in delete_all_overlays
10173 to avoid redundant calls to unchain_overlay.
10174 * buffer.c (drop_overlay): New function.
10175 (delete_all_overlays, Fdelete_overlay): Use it.
10176 * minibuf.c (get_minibuffer): Fix comment.
10178 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10180 Port to OpenBSD 5.1 amd64.
10181 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10182 This is needed for OpenBSD, and should be harmless on all BSD systems.
10183 Also, include <sys/sysctl.h>, as it should be available on all
10184 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10185 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10186 use p_pid member, not kp_proc.pid.
10188 2012-07-06 Glenn Morris <rgm@gnu.org>
10190 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10192 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10194 More xmalloc and related cleanup.
10195 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

10203 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10205 Omit needless casts involving void * pointers and allocation.
10206 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10207 as the former is more robust if P's type is changed.
10208 Prefer xzalloc to xmalloc + memset 0.
10209 Simplify malloc-or-realloc to realloc.
10210 Don't worry about xmalloc returning a null pointer.
10211 Prefer xstrdup to xmalloc + strcpy.
10212 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10214 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10215 alloca of a constant.
10217 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10219 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10220 hscroll is larger than the line width. Fixes long and futile
10221 looping inside extend_face_to_end_of_line (on a TTY) producing
10222 glyphs that are not needed and thrown away.
10224 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10226 * marker.c (set_marker_restricted_both): Simplify by using
10229 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

10240 followed by gtk_box_set_homogeneous (Bug#11768).
10241 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10242 (update_theme_scrollbar_width, xg_create_scroll_bar):
10243 Use gtk_scrollbar_new (Bug#11768).

10245 (is_box_type): New function (Bug#11768).
10246 (xg_tool_item_stale_p): Call is_box_type.
10247 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10248 with default display (Bug#11768).
10250 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10252 * xdisp.c (window_hscroll_limited): New function.
10253 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10254 coordinates when window's hscroll is set to insanely large
10255 values. (Bug#11857)
10257 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10321 Problem reported by Troels Nielsen in
10322 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10324 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10326 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10327 This should be fixed in a better way; see Eli Zaretskii in
10328 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10329 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10331 * fileio.c (time_error_value): Rename from special_mtime.
10332 The old name's problems were noted by Eli Zaretskii in
10333 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10335 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10336 This variable's comment says Emacs needs at least one GDB-visible
10337 symbol of type enum pvec_type, to work around GDB problems.
10338 The symbol's value doesn't matter.
10340 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10341 that causes compilation to fail on pre-C99 compilers.
10343 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10345 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10346 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10348 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10350 * buffer.c (init_buffer_once): Fix initialization of
10351 headers for buffer_defaults and buffer_local_symbols.
10352 Reported by Juanma Barranquero <lekktu@gmail.com>.
10354 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>

10370 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10371 abusing vector->header.next.nbytes.
10372 (live_vector_p): Use PVEC_TYPE.
10373 (mark_object): Adapt code to extract pvectype. Use switch.
10375 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10377 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10378 Tighten new eassert a bit.
10380 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10382 Fix compilation with --enable-gcc-warnings and -O1
10383 optimization level.
10384 * doprnt.c (doprnt): Change type of tem to int, initialize
10385 to avoid compiler warning. Add eassert.
10386 * search.c (simple_search): Initialize match_byte to avoid
10387 compiler warning. Add eassert.
10389 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10391 Avoid weird behavior with large horizontal scrolls.
10392 Without this change, for example, large hscroll values would
10393 mess up Emacs's display on Fedora 15 x86, presumably due to
10394 overflows in int calculations in the display code.
10395 Also, if buffers had long lines, Emacs would freeze.
10396 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10397 (set_window_hscroll): New function, containing the old guts of
10398 Fset_window_hscroll. Return the clipped value.
10399 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10400 This avoids the need to check against PTRDIFF_MAX.
10402 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10404 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10406 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10408 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10410 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10411 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10412 since GCC 4.4.6 issues a bogus warning for them.
10414 Fix bugs in file timestamp newness comparisons.
10415 * fileio.c (Ffile_newer_than_file_p):
10416 * lread.c (Fload): Use full timestamp resolution of files,
10417 not just the 1-second resolution, so that files that are only
10418 slightly newer still count as newer.
10419 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10420 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10422 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10424 * fileio.c: Improve handling of file time marker. (Bug#11852)
10425 (special_mtime): New function.
10426 (Finsert_file_contents, Fverify_visited_file_modtime):
10427 Use it to set special mtime values consistently.
10429 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10431 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10432 marker for non-existing file. (Bug#11852)
10434 2012-07-03 Glenn Morris <rgm@gnu.org>
10436 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10437 and did not make it into globals.h).
10439 2012-07-03 Tom Tromey <tromey@redhat.com>
10441 * window.c (Fset_window_margins, Fset_window_fringes)
10442 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10443 * textprop.c (Fprevious_property_change): No longer static.
10444 * syntax.c (Fsyntax_table_p): No longer static.
10445 * process.c (Fget_process, Fprocess_datagram_address): No longer
10447 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
10448 * keyboard.c (Fcommand_execute): No longer static.
10450 * insdel.c (Fcombine_after_change_execute): No longer static.

10466 * intervals.h: Remove EXFUNs.
10467 * fontset.h: Remove EXFUN.
10468 * font.h: Remove EXFUNs.
10469 * dosfns.c (system_process_attributes): Remove EXFUN.
10470 * keymap.h: Remove EXFUNs.
10471 * lisp.h: Remove EXFUNs.
10472 * w32term.h: Remove EXFUNs.
10473 * window.h: Remove EXFUNs.
10474 * xsettings.h: Remove EXFUN.
10475 * xterm.h: Remove EXFUN.
10477 2012-07-03 Glenn Morris <rgm@gnu.org>
10479 * lisp.h (Frandom): Make it visible to C.
10480 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10481 buffer for invisible buffers. (Bug#1229)
10483 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10485 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10486 values which aren't power of 2.
10487 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10488 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10491 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10493 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10495 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10497 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10499 * alloc.c (allocate_vector_block): Remove redundant
10500 calls to mallopt if DOUG_LEA_MALLOC is defined.
10501 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10502 avoid calls to mallopt if zero_vector is returned.
10504 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10506 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10507 is enabled, avoid dereferencing NULL current_sblock if
10510 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10512 Cleanup basic buffer management.
10513 * buffer.h (struct buffer): Change layout to use generic vector
10514 marking code. Fix some comments. Change type of 'clip_changed'
10515 to bitfield. Remove unused #ifndef old.
10516 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10517 (GET_OVERLAYS_AT): Fix indentation.
10518 (for_each_per_buffer_object_at): New macro.
10519 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10520 (Fbuffer_local_variables): Use it.
10521 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10522 * alloc.c (allocate_buffer): Adjust to match new layout of
10523 struct buffer. Fix comment.
10524 (mark_overlay): New function.
10525 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10526 Lisp area of struct buffer.
10527 (mark_object): Use it. Adjust marking of misc objects
10528 and related comments.
10530 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10532 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10533 wrapper that is not needed because the wrapped code is a no-op (zero
10534 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10535 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10537 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10539 * alloc.c (mark_buffer): Simplify. Remove prototype.
10540 (mark_object): Add comment. Reorganize marking of vector-like
10541 objects. Use CHECK_LIVE for all vector-like objects except buffers
10542 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10543 Avoid redundant calls to mark_vectorlike for bool vectors.
10545 2012-06-30 Glenn Morris <rgm@gnu.org>
10547 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10549 * epaths.in (PATH_SITELOADSEARCH): New.
10550 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10551 This is rather than relying on --enable-locallisppath elements
10552 having "site-lisp" in their names. (Bug#10208#25, 11658)
10554 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10556 * w32proc.c (sys_select): Accept and ignore one more argument.
10558 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10560 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10561 (pselect) [!MS_DOS]: Redirect to sys_select.
10563 * sysdep.c: Don't include dos.h and dosfns.h.
10565 * process.c (sys_select):
10566 * msdos.c (sys_select): Accept one more argument and ignore it.
10568 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10569 adapt data types and code to that.
10572 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10573 which clashes with the gnulib function of the same name.
10575 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10577 * font.c (font_style_to_value, font_style_symbolic)
10578 (font_prop_validate_style): Add type checks for values in
10581 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10583 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10586 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10588 * xdisp.c (try_window_id): Undo last change.
10590 * w32.c (getwd): Adjust commentary about startup_dir.
10591 (init_environment): Always call sys_access, even in non-MSVC
10592 builds. Don't chdir to the directory of the Emacs executable.
10593 This undoes code from 1997 which was justified by the need to
10594 "avoid conflicts when removing and renaming directories". But its
10595 downside was that every relative file name was being interpreted
10596 relative to the directory of the Emacs executable, which can never
10597 be TRT. In particular, it broke sys_access when called with
10598 relative file names.
10599 (sys_access): Map GetLastError to errno.
10601 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10603 * window.h (struct window): Change type of 'fringes_outside_margins'
10604 to bitfield. Fix comment. Adjust users accordingly.
10605 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10607 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10610 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10612 * gnutls.c (emacs_gnutls_handshake):
10613 Add QUIT to make the loop interruptible.
10615 2012-06-29 Glenn Morris <rgm@gnu.org>
10617 * charset.c (init_charset): Make lack of etc/charsets fatal.
10619 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10621 * editfns.c (region_limit): Fix type mismatch.
10623 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10625 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10626 undefined. Convert from xassert to eassert.
10627 * nsmenu.m: Convert from xassert to eassert.
10628 * nsterm.m: Likewise.
10630 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10632 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10634 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10636 Avoid integer overflow on scroll-left and scroll-right.
10637 * window.c (HSCROLL_MAX): New macro.
10638 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10639 overflow when requested scroll falls outside ptrdiff_t range.
10641 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10643 * window.h (struct window): Change type of 'hscroll',
10644 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10645 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10646 Adjust users accordingly.
10647 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10648 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10649 from EMACS_INT to ptrdiff_t.
10650 (make_window): Omit redundant initialization.
10652 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

10669 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10670 adjust comments accordingly.

10719 * alloc.c (allocate_string_data): Remove dead code.
10720 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to

10723 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10725 * alloc.c (allocate_string): Omit intervals initialization.

10751 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10752 when building with Clang.

10783 * alloc.c: Remove build_string.

10791 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10793 Use sprintf return value instead of invoking strlen on result.
10794 In the old days this wasn't portable, since some sprintf
10795 implementations returned char *. But they died out years ago and
10796 Emacs already assumes sprintf returns int.
10797 Similarly for float_to_string.
10798 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10799 * ccl.c (ccl_driver):
10800 * character.c (string_escape_byte8):

10803 * print.c (print_object):
10804 * xdisp.c (message_dolog):
10805 * xfns.c (syms_of_xfns):
10806 Use sprintf or float_to_string result to avoid need to call strlen.
10807 * data.c (Fnumber_to_string):
10808 Use make_unibyte_string, since the string must be ASCII.
10809 * lisp.h, print.c (float_to_string): Now returns int length.
10810 * term.c (produce_glyphless_glyph):
10811 Use sprintf result rather than recomputing it.
10813 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10814 * Makefile.in (ALL_CFLAGS):
10815 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10820 * dispextern.h (xstrcasecmp): Define to library function
10821 strcasecmp if available.

10839 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10840 sprintf already null-terminates its output.
10842 * xfns.c (x_window): Remove redundant cast.
10844 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10846 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10847 `const char *' to `char *' to avoid compiler warning.
10849 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10851 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10852 instead of truncating it to 63 (admittedly a generous limit).

10911 * dispnew.c (Fsleep_for, sit_for):
10912 * keyboard.c (kbd_buffer_get_event):
10913 * process.c (Faccept_process_output):
10914 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10915 This improves on the previous patch, which introduced a bug
10916 when time_t is unsigned and as wide as intmax_t.
10917 See <http://bugs.gnu.org/9000#51>.

10948 language ID in the event parameters.
10950 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10951 event.code, not the obscure "character set ID".

10982 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10984 Support higher-resolution time stamps (Bug#9000).
10985 The time stamps are only nanosecond-resolution at the C level,
10986 since that's the best that any real-world system supports now.
10987 But they are picosecond-resolution at the Lisp level, as that's
10988 easy, and leaves room for future OS improvements.
10990 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10993 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10994 Don't get current time unless it's needed.
10996 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10997 now provides it if it's absent.
10998 (start_atimer): Port to higher-res time stamps.
10999 Check for time stamp overflow. Don't get current time more
11000 often than is needed.
11002 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11003 Include systime.h, not time.h.
11004 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11006 * dired.c: Include stat-time.h.
11007 (Ffile-attributes): File times now have higher resolution.
11009 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11010 (struct image): Timestamp now has higher resolution.
11012 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11013 has at least microseconds now. All uses removed.
11014 (update_frame, update_single_window, update_window, update_frame_1)
11015 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11016 (duration_to_sec_usec): Remove; no longer needed.
11018 * editfns.c (time_overflow): Now extern.
11019 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

11024 (decode_time_components, lisp_seconds_argument): New functions.
11025 (make_time): Now static.
11026 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11027 Report an error if the time is invalid, rather than having the caller
11030 * fileio.c: Include <stat-time.h>
11031 (Fcopy_file): Copy higher-resolution time stamps.
11032 Prefer to set the time stamp via a file descriptor if that works.
11033 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11034 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11035 (Fvisited_file_modtime, Fset_visited_file_modtime):
11036 Support higher-resolution time stamps.
11038 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11040 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11042 * image.c (prepare_image_for_display, clear_image_cache)
11043 (lookup_image): Port to higer-resolution time stamps.
11045 * keyboard.c (start_polling, bind_polling_period):
11046 Check for time stamp overflow.
11047 (read_char, kbd_buffer_get_event, timer_start_idle)
11048 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11049 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11050 Port to higher-resolution time stamps. Do not assume time_t is signed.
11051 (decode_timer): New function. Timers are now vectors of length 9,
11052 not 8, to accommodate the picosecond component.
11053 (timer_check_2): Use it.
11055 * nsterm.m (select_timeout, timeval_subtract): Remove.
11056 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11057 as they're a bit more accurate and handle overflow better.
11058 (ns_select): Change prototype to be compatible with pselect.
11059 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11060 * nsterm.h (ns_select): Adjust prototype.
11062 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11063 us-resolution time stamps.
11064 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11066 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11068 * lisp.h (time_overflow): New decl.
11069 (wait_reading_process_output): First arg is now intmax_t, not int,
11070 to accommodate larger waits.
11072 * process.h (struct Lisp_Process.read_output_delay):
11073 Now counts nanoseconds, not microseconds.
11074 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11076 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11077 (wait_reading_process_output):
11078 Port to ns-resolution time stamps.
11079 (Faccept_process_output, wait_reading_process_output):
11080 Check for time stamp overflow. Do not assume time_t is signed.
11081 (select_wrapper): Remove; we now use pselect.
11082 (Fprocess_attributes): Now generates ns-resolution time stamps.
11084 * sysdep.c: Include utimens.h. Don't include utime.h
11085 or worry about struct utimbuf; gnulib does that for us now.
11086 (gettimeofday): Remove; gnulib provides a substitute.
11087 (make_timeval): New function.
11088 (set_file_times): Now sets ns-resolution time stamps.
11089 New arg FD; all uses changed.
11090 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11091 (system_process_attributes):
11092 Now returns ns-resolution time stamp. All uses changed.
11093 Check for time stamp overflow.
11095 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11096 provides a substitute now.
11098 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11099 since it guarantees struct timespec.
11100 (EMACS_TIME): Now struct timespec, so that we can support
11101 ns-resolution time stamps.
11102 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11103 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11104 (EMACS_USECS): Remove.
11105 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11106 so multiply the arg by 1000 before storing it.
11107 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11109 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11110 Port to ns-resolution time stamps.
11111 (EMACS_TIME_NEG_P): Remove; replaced by....
11112 (EMACS_TIME_SIGN): New macro.

11114 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11115 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11116 (make_timeval, make_lisp_time, decode_time_components): New decls.
11117 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11118 that it mishandled time_t overflow. You can't compare by subtracting!
11119 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11120 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11122 * term.c: Include <sys/time.h>.
11123 (timeval_to_Time): New function, for proper overflow wraparound.
11124 (term_mouse_position, term_mouse_click): Use it.
11126 * undo.c (record_first_change): Support higher-resolution time stamps
11127 in the undo buffer.
11128 (Fprimitive_undo): Use them when restoring time stamps.
11130 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11131 (w32_get_internal_run_time):
11132 Port to higher-resolution Emacs time stamps.
11133 (ltime): Now accepts single 64-bit integer, as that's more convenient
11136 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11138 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11139 for compatibility with pselect. Support ns-resolution time stamps.
11141 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11143 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11144 Check for time stamp overflow, and support ns-resolution time stamps.
11146 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11147 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11148 (timeval_subtract): Remove; no longer needed.
11149 (XTflash, XTring_bell, x_wait_for_event):
11150 Port to ns-resolution time stamps. Don't assume time_t is signed.
11152 2012-06-22 Chong Yidong <cyd@gnu.org>

11156 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11158 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11159 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11160 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11161 staticidx goes up to 1597 out of 1600 = 0x640.)
11163 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11165 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11166 Otherwise, the umask might be mistakenly 0 while handling input signals.
11168 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

11177 access to `contents' member of Lisp_Vector objects with AREF and ASET
11180 2012-06-19 Chong Yidong <cyd@gnu.org>
11182 * frame.c (delete_frame): When selecting a frame on a different
11183 text terminal, do not alter the terminal's top-frame.

11186 frame's selected window and its terminal's top-frame.
11187 (unwind_format_mode_line): Restore them.
11188 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11190 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11191 since tty frames can be explicitly named.
11192 (prepare_menu_bars): Likewise.
11194 * term.c (Ftty_top_frame): New function.
11196 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11199 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11200 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11201 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11202 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11203 (METER_1, METER_2): Simplify.
11205 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

11209 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11211 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11212 gets killed during executing of this function (Bug#11665).
11213 Try to always return Qt when the buffer has been actually killed.
11214 (Vkill_buffer_query_functions): In doc-string say that functions
11215 run by this hook should not change the current buffer.
11217 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11219 Fix recently-introduced process.c problems found by static checking.
11220 * process.c (write_queue_push, write_queue_pop, send_process):
11221 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11222 (write_queue_pop): Fix pointer signedness problem.
11223 (send_process): Remove unused local.
11225 2012-06-17 Chong Yidong <cyd@gnu.org>

11239 * lisp.h (eassert): Assume C89 or later.
11240 This removes the need for CHECK.
11241 (CHECK): Remove. Its comments about always evaluating its
11242 argument were confusing, as 'eassert' typically does not evaluate
11245 * coding.c (produce_chars): Use ptrdiff_t, not int.
11247 * xterm.c (x_draw_underwave): Check for integer overflow.
11248 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
11250 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
11252 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
11253 referenced (Bug#11583).

11346 indexing into it->string_overlays array. (Bug#11653)
11347 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

11370 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
11371 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

11422 * alloc.c (make_number) [!defined make_number]:
11423 Remove, as lisp.h always defines this now.
11424 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.

11433 code works fine either way, and efficiency is not a concern here,
11434 as the union type is for debugging, not for production.
11435 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11436 Use an inline function on all platforms when using the union type,
11437 since this is simpler and 'static inline' can be used portably
11439 (LISP_INITIALLY_ZERO): New macro.
11440 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11441 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11544 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11546 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11548 * alloc.c (allocate_vectorlike): Fix last change.

11581 * doprnt.c (doprnt): Truncate multibyte char correctly.
11582 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11583 would mishandle a string argument "Xc" if X was a multibyte
11584 character of length 2: it would truncate after X's first byte
11585 rather than including all of X.
11587 2012-06-06 Chong Yidong <cyd@gnu.org>
11589 * buffer.c (word_wrap): Doc fix.

11636 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11638 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11639 Convert pctcpu and pctmem to Lisp float properly.
11640 Let the compiler fold better, as 100.0/0x8000 is exact.
11642 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11644 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11651 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11653 For a 'struct window', replace some Lisp_Object fields to
11654 bitfields where appropriate, remove unused fields.
11655 * window.h (struct window): Remove unused 'last_mark_x' and
11656 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11657 change its type from Lisp_Object to bitfield.
11658 Change type of 'force_start', 'optional_new_start',
11659 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

11666 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11667 Use 'float' consistently, rather than 'float' in most places
11668 and 'double' in a couple of places.
11670 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11672 * xdisp.c (handle_stop): Detect whether we have overlay strings
11673 loaded by testing it->current.overlay_string_index to be
11674 non-negative, instead of checking whether n_overlay_strings is
11675 positive. (Bug#11587)
11677 2012-05-31 Chong Yidong <cyd@gnu.org>
11679 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11685 * search.c (search_buffer): Remove calls to
11686 r_alloc_inhibit_buffer_relocation, as it is now called by
11687 maybe_unify_char, which was the cause of relocation of buffer text
11690 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11692 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11693 for the duration of call to load_charset, to avoid problems with
11694 callers of maybe_unify_char that access buffer text through C
11697 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11698 decrement the inhibition flag, instead of just setting or
11701 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11703 Remove obsolete '#define static' cruft.
11704 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11705 This #undef was "temporary" in 2000; it is no longer needed
11706 now that '#define static' has gone away.
11707 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11708 (gray_bitmap_bits): Remove; no longer needed.

11721 (safe_bcopy): Remove decl; no longer has that name.
11722 (main): Coalesce #if into single bit of code, for simplicity.
11723 Cast pointers to uintptr_t, since standard libraries want integers

11752 Do not create empty overlays with the evaporate property (Bug#9642).
11753 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11754 Bug#9642, but explicitly check that the buffer the overlay would
11755 be moved to is live and rearrange lines to make sure that errors
11756 will not put the overlay in an inconsistent state.
11757 (Fdelete_overlay): Cosmetics.
11759 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11761 * w32term.c (my_bring_window_to_top): New function.
11762 (x_raise_frame): Use handle returned by DeferWindowPos, which
11763 could be different from the original one.
11764 Call my_bring_window_to_top instead of my_set_foreground_window.
11767 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11768 by calling BringWindowToTop.

11773 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11775 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11776 This avoids undefined behavior that might cause the eassert
11777 to not catch an out-of-range value.
11779 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11781 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11782 Update dependencies.
11784 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11786 * bidi.c (bidi_mirror_char): Fix last change.
11788 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11791 when referring to sectname field in printf format.
11793 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11795 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11796 Only r_alloc_inhibit_buffer_relocation needed to be added;
11797 the others were already declared.
11799 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11800 before checking whether it's out of range. Put the check inside
11802 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11804 2012-05-27 Ken Brown <kbrown@cornell.edu>
11806 * callproc.c (Fcall_process): Restore a line that was accidentally
11807 commented out in the 2011-02-13 change (bug#11547).
11809 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11811 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11812 defined on ralloc.c.
11814 * buffer.c [REL_ALLOC]: Remove prototypes of
11815 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11816 they are now on lisp.h.
11818 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11820 * search.c (search_buffer): Use it to inhibit relocation of buffer
11821 text while re_search_2 is doing its job, because re_search_2 is
11822 passed C pointers to buffer text. (Bug#11519)
11824 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11825 Update value to 24.
11827 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11828 state after an additional call to move_it_in_display_line_to, keep
11829 the values of it->max_ascent and it->max_descent found for the
11831 (pos_visible_p): Revert the comparison against bottom_y to what it
11832 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11835 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11837 Fix coding-related core dumps with gcc -ftrapv.
11838 The code was computing A - B, where A and B are pointers, and B is
11839 random garbage. This can lead to core dumps on platforms that
11840 have special pointer registers, and it also leads to core dumps on
11841 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11842 A - B only when B is initialized properly.
11843 * coding.c (coding_set_source, coding_set_destination): Return void.
11844 (coding_change_source, coding_change_destinations): New functions,
11845 with the old behaviors of coding_set_source and coding_set_destination.
11846 All callers that need an offset changed to use these new functions.
11848 2012-05-26 Glenn Morris <rgm@gnu.org>
11850 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11852 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11854 Extend mouse support on W32 text-mode console.
11855 * xdisp.c (draw_row_with_mouse_face):
11856 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11858 * w32console.c: Include window.h.
11859 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11861 (initialize_w32_display): Initialize mouse-highlight data.
11863 * w32inevt.c: Include termchar.h and window.h.
11864 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11865 moves, call note_mouse_highlight. If help_echo changed, call
11866 gen_help_event to produce help-echo message in the echo area.
11867 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11870 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11872 * lread.c (read1): Simplify slightly to avoid an overflow warning
11873 with GCC 4.7.0 on x86-64.
11875 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11877 * bidi.c (bidi_mirror_char): Revert last change: an int is
11878 definitely wide enough here.
11880 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11882 Fix integer width and related bugs (Bug#9874).

11884 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11885 (string_bytes, check_sblock, allocate_string_data):
11886 (compact_small_strings, Fmake_bool_vector, make_string)

11889 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11890 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11892 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11893 (allocate_pseudovector):
11894 Use int, not EMACS_INT, where int is wide enough.
11895 (inhibit_garbage_collection, Fgarbage_collect):
11896 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11897 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11898 int might not be wide enough.
11899 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11900 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11901 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11902 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11903 (bidi_level_of_next_char, bidi_move_to_visually_next):

11905 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11906 (Fkill_buffer, Fset_buffer_major_mode)
11907 (advance_to_char_boundary, Fbuffer_swap_text)

11914 (Foverlay_recenter, last_overlay_modification_hooks_used)
11915 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11916 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11917 (validate_region): Omit unnecessary test for b <= e,
11918 since that's guaranteed by the previous test.
11919 (adjust_overlays_for_delete): Avoid pos + length overflow.
11920 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11921 (report_overlay_modification):
11922 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11923 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11924 Omit pointer cast, which isn't needed anyway, and doesn't work
11925 after the EMACS_INT -> ptrdiff_t change.
11926 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11927 * buffer.h: Adjust decls to match defn changes elsewhere.
11928 (struct buffer_text, struct buffer):
11929 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11930 Use EMACS_INT, not int, where int might not be wide enough.
11931 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11932 not int, to avoid needless 32-bit limit on 64-bit hosts.
11933 (exec_byte_code): Use tighter memory-full test, one that checks
11934 for alloca overflow. Don't compute the address of the object just
11935 before an array, as that's not portable. Use EMACS_INT, not
11936 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11937 * callint.c (Fcall_interactively):
11938 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11939 * callproc.c (call_process_kill, Fcall_process):
11940 Don't assume pid_t fits into an Emacs fixnum.
11941 (call_process_cleanup, Fcall_process, child_setup):

11949 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11950 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11951 (casify_object): Avoid integer overflow when overallocating buffer.
11952 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11953 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11954 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11955 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11956 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11957 integers are now checked earlier. All uses replaced with XINT.
11959 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11960 For CCL_MapSingle, check that content and value are in int range.
11961 (ccl_driver, Fregister_code_conversion_map):
11962 Check that Vcode_version_map_vector is a vector.
11963 (resolve_symbol_ccl_program): Check that vector header is in range.
11964 Always copy the vector, so that we can check its contents reliably
11965 now rather than having to recheck each instruction as it's being
11966 executed. Check that vector words fit in 'int'.
11967 (ccl_get_compiled_code, Fregister_ccl_program)
11968 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11969 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11970 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11971 contents are in range.
11972 (Fccl_execute_on_string): Check that status is in range.
11973 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11974 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11975 Accept and return EMACS_INT, not int, because callers can pass values
11976 out of 'int' range.

11978 (multibyte_chars_in_text, parse_str_as_multibyte)

11981 (string_escape_byte8, Fget_byte):
11982 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11983 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11984 avoid mishandling large integers.
11985 * character.h: Adjust decls to match defn changes elsewhere.
11986 * charset.c (load_charset_map_from_file, find_charsets_in_text)

11991 Don't assume fixnum fits in int.
11992 (load_charset_map_from_vector, Fmap_charset_chars):
11993 Remove now-unnecessary CHECK_NATNUMs.
11994 (Fdefine_charset_internal): Check ranges here, more carefully.
11995 Don't rely on undefined behavior with signed left shift overflow.
11996 Don't assume unsigned int fits into fixnum, or that fixnum fits
11997 into unsigned int. Don't require max_code to be a valid fixnum;
11998 that's not true for gb10830 4-byte on a 32-bit host. Allow
11999 invalid_code to be a cons, for the same reason. Require code_offset
12000 to be a character. Avoid int overflow if max_char is close
12002 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12003 this is intended anyway and avoids some undefined behavior.
12004 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12005 INDEX_TO_CODE_POINT, as that's what it expects.
12006 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12007 * charset.h (DECODE_CHAR): Return int, not unsigned;
12008 this is what was intended anyway, and it avoids undefined behavior.
12009 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12010 integer-overflow issues.
12011 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12012 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12013 where the argument is EMACS_INT, and this behavior is not intended.
12014 * chartab.c (Fmake_char_table, Fset_char_table_range)
12015 (uniprop_get_decoder, uniprop_get_encoder):
12016 Don't assume fixnum fits in int.
12017 * cmds.c (move_point): New function, that does the gist of
12018 Fforward_char and Fbackward_char, but does so while checking
12019 for integer overflow more accurately.
12020 (Fforward_char, Fbackward_char): Use it.
12021 (Fforward_line, Fend_of_line, internal_self_insert)
12022 (internal_self_insert):
12023 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12024 Fix a FIXME, by checking for integer overflow when calculating
12025 target_clm and actual_clm.

12082 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12083 Do not attempt to compute the address of the object just before a
12084 buffer; this is not portable.

12821 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12822 already have overlays loaded.
12823 (handle_single_display_spec): Before returning without displaying
12824 fringe bitmap, synchronize the bidi iterator with the main display
12825 iterator, by calling iterate_out_of_display_property.
12826 (iterate_out_of_display_property): Detect buffer iteration by
12827 testing that it->string is a Lisp string.
12828 (get_next_display_element): When the current object is exhausted,
12829 and there's something on it->stack, call set_iterator_to_next to
12830 proceed with what's on the stack, instead of returning zero.
12831 (set_iterator_to_next): If called at the end of a Lisp string,
12832 proceed to consider_string_end without incrementing string
12833 position. Don't increment display vector index past the end of
12834 the display vector. (Bug#11417)
12835 (pos_visible_p): Don't report a position visible when move_it_to
12836 stopped at the last line of window, which happens to be scanned
12837 backwards by the bidi iteration. (Bug#11464)
12839 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12841 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12842 and right-margin display specs even if the spec is invalid or we
12843 are on a TTY, and thus unable to display on the fringes.
12844 That's because the text with the property will not be displayed anyway,
12845 so we need to signal to the caller that this is a "replacing"
12846 display spec. This fixes display when the spec is invalid or we
12849 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12851 * unexaix.c (make_hdr): Fix typo in prototype.
12852 This bug broke the build on AIX. Problem reported by Gilles Pion.
12854 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12856 * keyboard.c (kbd_buffer_get_event): Read special events also in
12857 batch mode. (Bug#11415)
12859 2012-05-12 Glenn Morris <rgm@gnu.org>
12861 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12863 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12865 * lisp.mk (lisp): Add newcomment.elc.
12867 2012-05-12 Glenn Morris <rgm@gnu.org>
12869 * Makefile.in (MKDIR_P): New, set by configure.
12870 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12872 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12874 Remove unused function hourglass_started.
12875 * dispextern.h (hourglass_started):
12876 * w32fns.c (hourglass_started):
12877 * xdisp.c (hourglass_started): Remove.
12879 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12881 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12882 Update dependencies.
12884 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12886 * xgselect.c (xg_select): Put maxfds+1 into a var.
12887 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12889 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12891 2012-05-10 Dave Abrahams <dave@boostpro.com>
12893 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12894 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12896 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12898 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12899 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12900 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12901 Initialize xd_registered_buses.
12903 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12905 Untag more efficiently if USE_LSB_TAG.
12906 This is based on a proposal by YAMAMOTO Mitsuharu in
12907 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12908 For an admittedly artificial (nth 8000 longlist) benchmark on
12909 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12910 Emacs's overall text size by 1%.
12911 * lisp.h (XUNTAG): New macro.
12912 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12913 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12914 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12915 * eval.c (Fautoload):
12916 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12917 * frame.h (XFRAME): Use XUNTAG.
12919 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12920 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12921 Remove unportable assumptions about print widths of types like
12923 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12924 intptr_t when converting between pointer and integer, to avoid GCC
12925 warnings about wrong width.
12927 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12929 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12930 stack for each reader_thread, instead of defaulting to 8MB
12931 determined by the linker. This avoids failures in creating
12932 subprocesses on Windows 7, see the discussion in this thread:
12933 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12935 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12937 Fix up display of the *Minibuf-0* buffer in the mini window.
12938 * keyboard.c (read_char): Don't clear the echo area if there's no
12940 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12941 contents of *Minibuf-0*) if there's no message displayed in its stead.
12943 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12945 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12948 2012-05-06 Chong Yidong <cyd@gnu.org>
12950 * lisp.mk (lisp): Update.
12952 2012-05-05 Jim Meyering <meyering@redhat.com>
12954 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12956 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12958 * data.c (PUT_ERROR): New macro.
12959 (syms_of_data): Use it. Add new error type `user-error'.
12960 * undo.c (user_error): New function.
12961 (Fprimitive_undo): Use it.
12962 * print.c (print_error_message): Adjust print style for `user-error'.
12963 * keyboard.c (user_error): New function.
12964 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12966 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12968 Do not limit current-time-string to years 1000..9999.
12969 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12970 (Fcurrent_time_string): Support any year that is supported by the
12971 underlying localtime representation. Don't use asctime, as it
12972 has undefined behavior for years outside the range -999..9999.
12974 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12976 Fix race conditions involving setenv, gmtime, localtime, asctime.
12977 Without this fix, interrupts could mess up code that uses these
12978 nonreentrant functions, since setting TZ invalidates existing
12979 tm_zone or tzname values, and since most of these functions return
12980 pointers to static storage.
12981 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12982 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12983 Grow the critical sections to include not just invoking
12984 localtime/gmtime, but also accessing these functions' results
12985 including their tm_zone values if any, and any related TZ setting.
12986 (format_time_string): Last arg is now struct tm *, not struct tm **,
12987 so that the struct tm is saved in the critical section.
12988 All callers changed. Simplify allocation of initial buffer, partly
12989 motivated by the fact that memory allocation needs to be outside
12990 the critical section.
12992 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12994 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12995 with RESET_INTERVAL.
12997 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12998 Remove duplicated buffer name initialization.
13000 2012-05-02 Jim Meyering <jim@meyering.net>
13002 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13004 * xfns.c (x_window): Use xstrdup (Bug#11375).
13006 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13008 * xdisp.c (pos_visible_p): If already at a newline from the
13009 display string before the 'while' loop, don't walk back the glyphs
13010 from it3.glyph_row. Solves assertion violation when the display
13011 string begins with a newline (egg.el). (Bug#11367)
13013 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13015 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13018 2012-05-01 Glenn Morris <rgm@gnu.org>
13020 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13021 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13022 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13023 All were removed before 23.1.
13025 * dispnew.c: Remove HAVE_LIBNCURSES test;
13026 it is always true on relevant platforms.
13028 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13029 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13031 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13033 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13035 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13036 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13039 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13041 Do not avoid creating empty evaporating overlays (Bug#9642).
13042 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13043 That is, do not delete an evaporating overlay if it becomes
13044 empty after its bounds are adjusted to fit within its buffer.
13045 This fix caused other problems, and I'm reverting it until we get
13046 to the bottom of them.
13048 2012-04-27 Chong Yidong <cyd@gnu.org>
13050 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13052 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13054 * xdisp.c (pos_visible_p): If the window start position is beyond
13055 ZV, start the display from buffer beginning. Prevents assertion
13056 violation in init_iterator when the minibuffer window is scrolled
13057 via the scroll bar.
13059 * window.c (window_scroll_pixel_based): Likewise.
13061 2012-04-27 Chong Yidong <cyd@gnu.org>
13063 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13065 2012-04-27 Glenn Morris <rgm@gnu.org>
13067 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13068 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13070 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13072 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13073 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13075 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13077 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13078 display element, check also the underlying string or buffer
13079 character. (Bug#11341)
13081 * w32menu.c: Include w32heap.h.
13082 (add_menu_item): If the call to AppendMenuW (via
13083 unicode_append_menu) fails, disable Unicode menus only if we are
13084 running on Windows 9X/Me.
13086 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13088 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13089 (xgetint): Add missing shift for LSB tags.
13091 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13093 * keyboard.c (read_char): Don't wipe echo area for select window
13094 events: These might get delayed via `mouse-autoselect-window'
13097 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13099 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13100 manipulation of :loaded-from data.
13102 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13104 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13105 now a cons (bug#11311).
13107 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13109 Do not create empty overlays with the evaporate property (Bug#9642).
13110 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13111 if it becomes empty after its bounds are adjusted to fit within
13112 its buffer. Without this fix, in a nonempty buffer (let ((o
13113 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13114 yields an empty overlay that has the evaporate property, which is
13115 not supposed to happen.
13117 Fix minor GTK3 problems found by static checking.
13118 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13119 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13120 (struct _EmacsFixedClass, emacs_fixed_get_type):
13121 Move decls here from emacsgtkfixed.h, since they needn't be public.
13122 (emacs_fixed_get_type): Now static.
13123 (emacs_fixed_class_init): Omit unused local.
13124 (emacs_fixed_child_type): Remove; unused.
13125 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13126 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13127 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13128 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13129 (EMACS_FIXED_GET_CLASS): Remove; unused.
13130 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13132 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13133 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13135 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13137 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13138 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13139 (__malloc_size_t, __malloc_ptrdiff_t):
13140 Remove. All uses removed, replaced by the definiens if needed,
13141 since we can assume C89 or better now.
13142 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13143 (protect_malloc_state, align, get_contiguous_space)
13144 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

13149 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13150 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13151 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13152 Define using prototypes, not old style.
13153 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

13155 (align): Don't assume that signed integer overflow wraps around.
13156 Omit unused local var.
13157 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

13159 Omit no-longer-needed casts.
13160 (valloc): Use getpagesize, not __getpagesize.
13161 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13162 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13164 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13166 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13168 Move functions from C to Lisp. Make non-blocking method calls
13169 the default. Implement further D-Bus standard interfaces.
13171 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

13199 (Fdbus_method_return_internal, Fdbus_method_error_internal)
13200 (Fdbus_send_signal, Fdbus_register_service)
13201 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

13211 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13213 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
13214 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
13215 Do not assume ptrdiff_t is the same width as 'int'.
13217 * alloc.c: Handle unusual debugging option combinations.
13218 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13219 since the two debugging options are incompatible.
13220 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13222 (mem_init, mem_insert, mem_insert_fixup):
13223 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
13224 (NEED_MEM_INSERT): Remove; no longer needed.
13226 2012-04-22 Leo Liu <sdl.web@gmail.com>

13230 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13232 * sysdep.c [__FreeBSD__]: Minor cleanups.
13233 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13234 Use Emacs indenting style more consistently. Avoid some casts.
13235 Use 'double' consistently rather than mixing 'float' and 'double'.
13237 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13239 * sysdep.c (list_system_processes, system_process_attributes):
13240 Add implementation for FreeBSD (Bug#5243).
13242 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>

13246 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13248 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13249 It is never used otherwise.
13251 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13253 * print.c (print_preprocess): Only check print_depth if print-circle
13255 (print_object): Check for cycles even when print-circle is nil and
13256 print-gensym is t, but only check print_depth if print-circle is nil.
13258 2012-04-20 Chong Yidong <cyd@gnu.org>
13260 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13261 set the status to "failed" and ensure that sentinel is run.
13263 2012-04-20 Glenn Morris <rgm@gnu.org>
13265 * process.c (Fset_process_inherit_coding_system_flag)
13266 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13276 farther than the first row after the header line, if any.
13277 Don't consider the header-line row as "partially visible", even if
13278 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
13280 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13290 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
13291 (ALL_CFLAGS): Use new macros rather than old.
13292 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

13294 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13295 -Wunused-result, -Wunused-variable. This should go away once
13296 the Emacs and Gnulib regex code is merged.
13297 (xmalloc, xrealloc): Now static.
13299 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

13316 New extern decls, to avoid calling undeclared functions.
13317 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13318 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13319 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13320 (NEED_MEM_INSERT): New macro.
13321 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13322 Remove one incorrect comment and fix another.

13336 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13337 Remove decls. This fixes an "It stinks!".
13339 * alloc.c (which_symbols): Fix alignment issue / type clash.
13341 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13343 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13344 (struct Lisp_Misc_Any): Likewise.
13345 (struct Lisp_Free): Likewise.
13346 * alloc.c (union aligned_Lisp_Symbol): Define.

13356 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13357 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13358 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13359 * s/netbsd.h, s/sol2-6.h:
13360 Remove definition of GC_MARK_STACK, since the default now works.
13361 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13362 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13363 no longer the default.
13364 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13366 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13368 * lread.c (lisp_file_lexically_bound_p):

13371 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13373 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13374 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

13383 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
13385 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13387 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13389 2012-04-11 Daniel Colascione <dancol@dancol.org>
13391 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13392 against is gone. It's better to use vfork now so that when Cygwin
13393 gains a new, working vfork, we use it automatically (bug#10398).
13395 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13397 * window.c (save_window_save): Obey window-point-insertion-type.

13413 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13415 * w32.c (w32_delayed_load): Record the full path of the library
13416 being loaded (bug#10424).
13418 2012-04-09 Glenn Morris <rgm@gnu.org>
13420 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13421 not just in the obarray, before snarfing them. (Bug#11036)
13423 * Makefile.in ($(leimdir)/leim-list.el):
13424 Pass EMACS rather than BUILT_EMACS.
13426 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13428 * process.c (make_process):
13429 * process.h: Add integer `gnutls_handshakes_tried' member to

13436 (emacs_gnutls_read): Use new log functions,
13437 `gnutls_handshakes_tried' process member, and
13438 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13439 attempts per process (connection).
13441 2012-04-09 Chong Yidong <cyd@gnu.org>
13443 * eval.c (Fuser_variable_p, user_variable_p_eh)
13444 (lisp_indirect_variable): Functions deleted.
13445 (Fdefvar): Caller changed.
13447 * callint.c (Finteractive, Fcall_interactively):
13448 * minibuf.c (Fread_variable): Callers changed.
13450 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13452 * xdisp.c (set_cursor_from_row): If the display string appears in
13453 the buffer at position that is closer to point than the position
13454 after the display string, display the cursor on the first glyph of
13455 the display string. Fixes cursor display when a 'display' text
13456 property immediately follows invisible text. (Bug#11094)
13458 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13460 composite.c: use 'double' consistently
13461 * composite.c (get_composition_id): Use 'double' consistently
13462 instead of converting 'float' to 'double' and vice versa; this is
13463 easier to understand and avoids a GCC warning.
13465 2012-04-09 Glenn Morris <rgm@gnu.org>
13467 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13468 preparation for dumping it with emacs. (Bug#4789)
13469 (leimdir): New variable.
13470 ($(leimdir)/leim-list.el): New rule.
13471 (emacs$(EXEEXT)): Depend on leim-list.el.

13489 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13490 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13491 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13492 objects, as mark_maybe_pointer will catch them otherwise.
13493 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13494 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13501 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13503 Support building on MS-Windows with libxml2.
13505 * makefile.w32-in (OBJ2): Add xml.$(O).
13506 (GLOBAL_SOURCES): Add xml.c.
13507 ($(BLD)/xml.$(O)): New dependency list.
13509 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13510 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13511 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13512 [!WINDOWSNT]: New macros.
13513 (init_libxml2_functions, libxml2_loaded_p): New functions.
13514 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13515 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13516 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13517 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13519 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13520 Call init_libxml2_functions before calling libxml2 functions.
13521 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13523 * emacs.c: Don't include libxml/parser.h.
13524 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13525 xmlCleanupParser directly.
13527 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13529 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13531 * indent.c (Fvertical_motion): If there is a display string at
13532 point, use it.vpos to compute how many lines to backtrack after
13533 move_it_to point. (Bug#11133)
13535 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13537 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13538 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13539 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13540 macros related to unification of CJK characters. For the details,
13541 see the discussion following the message here:
13542 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13544 2012-04-04 Chong Yidong <cyd@gnu.org>
13546 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13548 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13550 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13551 instead of alloca. (Bug#11138)
13553 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13555 * w32menu.c (is_simple_dialog): Properly check lisp types.
13558 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13560 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13561 position we get to after a call to move_it_to fails the
13562 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13563 only if we wind up in a string from display property. (Bug#11063)
13565 * window.c (Fdelete_other_windows_internal): Invalidate the row
13566 and column information about mouse highlight, so that redisplay
13567 restores it after reallocating the glyph matrices. (Bug#7464)
13569 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13570 string comes from a `display' text property, use the buffer
13571 position of that property as if we actually saw that position in
13573 (move_it_by_lines): Remove the assertion that
13574 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13575 violated when there's a before-string at the beginning of a line.
13578 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13580 * xdisp.c (append_space_for_newline): If the default face was
13581 remapped, use the remapped face for the appended newline.
13582 (extend_face_to_end_of_line): Use the remapped default face for
13583 extending the face to the end of the line.
13584 (display_line): Call extend_face_to_end_of_line when the default
13585 face was remapped. (Bug#11068)
13587 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13589 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13591 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

13607 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13608 (command_loop_1): Use it; inhibit selection update for
13609 handle-select-window too (Bug#8996).

13613 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13615 2012-03-25 Kenichi Handa <handa@m17n.org>
13617 * dispextern.h (struct glyph): Change the bit length of
13618 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13620 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13622 * s/ms-w32.h (tzname): Include time.h before redirecting to

13627 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13630 * xterm.c (XTread_socket): Only modify handling_signal if
13631 !SYNC_INPUT. (Bug#11080)
13633 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13635 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13636 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13637 when fetching a multibyte character consumes more bytes than
13638 CHAR_BYTES returns, due to unification of CJK characters in
13639 string_char. (Bug#11073)
13641 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13643 * process.c (wait_reading_process_output): Handle pty disconnect
13644 by refraining from sending oneself a SIGCHLD (bug#10933).
13646 2012-03-22 Chong Yidong <cyd@gnu.org>
13648 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13650 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13651 Mark string as coming from a prefix property.
13652 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13653 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13655 2012-03-21 Chong Yidong <cyd@gnu.org>
13657 * xfaces.c (Vface_remapping_alist): Doc fix.
13659 2012-03-20 Eli Zaretskii <eliz@gnu.org>

13673 it fit in a valid range (Bug#11003).
13675 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13677 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13678 that is not from display property, accept the row as a "cursor
13679 row" if one of the string's character has a non-nil `cursor'
13680 property. Fixes cursor positioning when there are newlines in
13681 overlay strings, e.g. in icomplete.el. (Bug#11035)
13683 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13685 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13687 2012-03-12 Chong Yidong <cyd@gnu.org>
13689 * eval.c (inhibit_lisp_code): Rename from
13690 inhibit_window_configuration_change_hook; move from window.c.
13692 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13693 * window.c (run_window_configuration_change_hook)
13694 (syms_of_window): Callers changed.
13696 2012-03-11 Chong Yidong <cyd@gnu.org>
13698 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13700 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13702 2012-03-10 Chong Yidong <cyd@gnu.org>
13704 * frame.c (other_visible_frames): Don't assume the selected frame
13705 is visible (Bug#10955).
13707 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13709 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

13717 2012-03-03 Glenn Morris <rgm@gnu.org>
13719 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13721 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13723 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13724 position past the first glyph_row that ends at ZV. (Bug#10902)
13725 (redisplay_window, next_element_from_string): Fix typos in
13727 (redisplay_window): Pass to move_it_vertically the margin in
13728 pixels, not in screen lines.
13730 2012-03-02 Glenn Morris <rgm@gnu.org>
13732 * buffer.c (buffer-list-update-hook): Doc fix.
13734 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13736 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13737 push_it before setting up the iterator for the first overlay
13738 string, even if we have an empty string loaded.
13739 (next_overlay_string): If there's an empty string on the iterator
13740 stack, pop the stack. (Bug#10903)
13742 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13744 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13745 Suggested by Stefan Monnier in
13746 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13747 * alloc.c (widen_to_Lisp_Object): New static function.
13748 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13749 and widening them to Lisp_Objects. This would work even if
13750 USE_LSB_TAG is defined and wide integers are used, which might
13751 happen in a future version of Emacs.
13753 2012-02-25 Chong Yidong <cyd@gnu.org>
13755 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

13760 before saving to clipboard manager.
13762 2012-02-24 Chong Yidong <cyd@gnu.org>
13764 * keyboard.c (process_special_events): Handle all X selection
13765 requests in kbd_buffer, not just the next one (Bug#8869).
13767 2012-02-23 Chong Yidong <cyd@gnu.org>
13769 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13770 call when setting menu-bar-lines and tool-bar-lines parameters.
13771 (unwind_create_frame_1): New helper function.
13773 * window.c (inhibit_window_configuration_change_hook): New var.

13792 when computing $valmask.
13794 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13795 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13796 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13797 It's useless in that case, and it can cause problems on hosts
13798 that allocate halves of EMACS_INT values separately.
13799 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13800 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13801 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13802 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13803 it avoids undefined behavior on hosts where shifting right by more
13804 than the word width has undefined behavior.
13806 2012-02-19 Chong Yidong <cyd@gnu.org>
13808 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13809 (Funhandled_file_name_directory, Ffile_name_as_directory)

13828 2012-02-15 Chong Yidong <cyd@gnu.org>
13830 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

13846 2012-02-12 Chong Yidong <cyd@gnu.org>
13848 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13849 as that creates a dangerous corner case.
13851 * window.c (Fdelete_window_internal): Invalidate the mouse
13852 highlight (Bug#9904).
13854 2012-02-12 Glenn Morris <rgm@gnu.org>

13886 * buffer.c (Fbuffer_local_variables)
13887 (buffer_lisp_local_variables): Handle unbound vars correctly;
13888 don't let Qunbound leak into Lisp.
13890 2012-02-07 Glenn Morris <rgm@gnu.org>
13892 * image.c (Fimagemagick_types): Doc fix.
13894 * image.c (imagemagick-render-type): Change it from a lisp object
13895 to an integer. Move the doc here from the lisp manual.

13929 Handle overflow when computing char display width (Bug#9496).
13930 * character.c (char_width): Return EMACS_INT, not int.
13931 (char_width, c_string_width): Check for overflow when
13932 computing the width; this is possible now that individual
13933 characters can have unbounded width. Problem introduced

13965 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13966 first 2 arguments are identical. This makes inserting large
13967 output from a subprocess an order of magnitude faster on
13968 MS-Windows, where all sbrk'ed memory is always contiguous.

14421 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14422 verifies glyph row's hash code--we have just reallocated the

14588 is set, removing the need for VIRT_ADDRESS_VARIES.
14589 (PURE_P): Use a more-efficient implementation that needs just one

14606 behave as if the cursor position were at the window margin.
14608 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14609 and the cursor position is out of bounds, behave as if the cursor
14610 position were at the window margin. (Bug#10075)
14612 2011-11-18 Chong Yidong <cyd@gnu.org>
14614 * window.c (Fwindow_combination_limit): Make first argument

14636 compute_line_metrics.
14637 (compute_line_metrics): Call row_hash, instead of computing the
14640 * dispnew.c (verify_row_hash): Call row_hash for computing the
14641 hash code of a row, instead of duplicating code from xdisp.c.
14643 * dispextern.h (row_hash): Add prototype.
14645 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14647 * frame.c (delete_frame): Don't delete the terminal when the last

14830 Otherwise, these inline functions do not conform to C99 and
14831 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14832 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14833 * intervals.c (adjust_intervals_for_insertion)

14836 (static_offset_intervals): Remove.
14837 (offset_intervals): Rewrite using the old contents of
14838 static_offset_intervals. The old version didn't conform to C99
14839 because an extern inline function contained a reference to an
14840 identifier with static linkage.

15120 extracted from Fw32_default_color_map.
15121 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15123 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15125 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15127 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15129 * keyboard.c (test_undefined): New function (bug#9751).
15130 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15132 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15134 * sysdep.c (init_sys_modes): Fix the check for the controlling
15135 terminal (Bug#6649).
15137 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15139 * dispextern.h (struct bidi_it): New member next_en_type.
15141 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15142 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15143 current character, check also for next_en_type being WEAK_EN.
15144 (bidi_resolve_weak): Don't enter the expensive loop if the current
15145 position is before next_en_pos. Record the bidi type of the first
15146 non-ET, non-BN character we find, in addition to its position.
15147 (bidi_level_of_next_char): Invalidate next_en_type when
15148 next_en_pos is over-stepped.
15150 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15152 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15153 * editfns.c: Rewrite current-time-zone so that it invokes
15154 the equivalent of (format-time-string "%Z") to get the time zone name.
15155 This fixes a bug when the time zone name contains characters that
15156 need converting from the system time locale to Emacs internal format.
15157 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15158 that patch fixed format-time-string to do the conversion, but
15159 I forgot to fix current-time-zone.
15160 (format_time_string): New function, containing most of
15161 what Fformat_time_string used to contain.
15162 (Fformat_time_string): Rewrite in terms of format_time_string.
15163 This doesn't change this function's behavior.
15164 (current-time-zone): Rewrite to use format_time_string.
15165 This fixes the bug reported by Michael Schierl in
15166 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15167 Jason Rumney's 2007-06-07 change worked around this bug, but
15169 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15171 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15173 * xdisp.c (start_display): If the character at POS is displayed
15174 via a display vector, reset IT->current.dpvec_index to zero.
15175 (try_window_reusing_current_matrix): If a line ends in a display
15176 vector or the next line starts in a display vector, continue
15177 redrawing the window even though the character position of
15178 start_row was reached.
15181 2011-10-18 Chong Yidong <cyd@gnu.org>
15183 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15184 with nobreak-char-display too.
15186 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15188 Fix part 3 of bug#9771.
15189 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15190 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15191 non-neutral characters if the current character is a paragraph
15192 separator (a.k.a. Newline). This avoids running the same
15193 expensive loop twice, once when we consume the preceding newline
15194 and the other time when the line actually needs to be displayed.
15195 Avoid the loop when we see neutrals on the base embedding level
15196 following a character whose directionality is the same as the
15197 paragraph's. This avoids running the expensive loop when a line
15198 ends in a long sequence of neutrals, like control characters.
15199 Add assertion against STRONG_AL type. Slightly rearrange code
15200 that determines the type of a neutral given the first non-neutral
15202 (bidi_level_of_next_char): Set next_en_pos to zero when
15203 invalidating its info.
15205 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15207 * xdisp.c (push_display_prop): Determine whether to record string
15208 or buffer position by IT->string, not by IT->method. Allow
15209 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15210 (move_it_vertically_backward): Don't look for character position
15211 immediately after the newline when in a continuation line.
15214 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15216 * window.c (coordinates_in_window): Rewrite and delabelize
15217 vertical border check. (Bug#5357) (Bug#9618)
15219 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15221 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15222 errors in XSetWindowBorder (bug#9310).
15224 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15226 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15227 avoid crash when xmalloc overrun checking is enabled.
15229 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15231 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15232 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15233 cursor motion with <left> and <right> arrow keys.
15235 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15236 some callers set that themselves.
15238 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15240 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15241 display string and the previous row comes from the same string and
15242 is empty. (Bug#9739) (Bug#9738)
15244 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15246 * doc.c (get_doc_string): Encode file name (bug#9735).
15248 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15250 * bidi.c (bidi_level_of_next_char):
15251 * xdisp.c (get_visually_first_element): Remove old incorrect
15252 comments regarding the Unicode Line Separator character.
15254 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15256 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15258 * alloc.c (Fgc_status): Do not access beyond zombies array
15259 boundary if nzombies > MAX_ZOMBIES.
15260 * alloc.c (dump_zombies): Add missing format specifier.
15262 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15264 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15265 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15267 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15268 Some packages use them to denote characters with modifiers.
15270 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15272 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15273 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15274 matching a pp-number. Rename parameter var to var1.
15276 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15278 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15280 2011-10-08 Glenn Morris <rgm@gnu.org>
15282 * callint.c (Fcall_interactively): Give a more explicit error for the
15283 'c' case with a non-character input. (Bug#8479)
15285 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15287 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15289 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15290 lines that are hscrolled on the left.
15292 * dispnew.c (buffer_posn_from_coords): Account for a possible
15293 presence of header-line. (Bug#4426)
15295 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15297 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15298 Don't advertise functionality which we discourage or doesn't work.
15300 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15302 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15303 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15304 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15305 this makes Emacs dump core during garbage collection on rare
15306 occasions. sizeof is obviously inferior to offsetof here, so
15307 stick with offsetof.
15308 (GC_POINTER_ALIGNMENT): New macro.
15309 (mark_memory): Omit 3rd (offset) arg; caller changed.
15310 Don't assume EMACS_INT alignment is the same as pointer alignment.
15312 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15314 * keyboard.c (read_key_sequence_remapped): New var.
15315 (read_key_sequence): Compute remapping in the right buffer.
15316 (command_loop_1): Use read_key_sequence's remapping directly.
15318 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15320 * dired.c (file_name_completion): Don't expand file name.
15321 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15322 before checking file name handler.
15324 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15325 they've been requested explicitly (bug#9591).
15327 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15329 * keymap.c (Fsingle_key_description): Use make_specified_string
15330 instead of build_string to build string from push_key_description.
15333 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15335 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15336 This fixes a Y2038 bug on 64-bit hosts.
15337 * buffer.c (reset_buffer):
15338 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15339 (Fclear_buffer_auto_save_failure):
15340 Use 0, not -1, to represent an unset failure time, since time_t
15341 might not be signed.
15343 Remove dependency on glibc malloc internals.
15344 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15345 Move back here from lisp.h, but with their new implementations.
15346 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15347 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15348 * charset.c (charset_table_init): New static var.
15349 (syms_of_charset): Use it instead of xmalloc. This removes a
15350 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15351 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15352 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15353 Move back to alloc.c.
15354 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15355 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15357 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15359 * nsterm.m (windowDidResize): Call x_set_window_size only when
15360 ns_in_resize is true. Otherwise set pixelwidth/height and
15361 call change_frame_size (Bug#9628).
15363 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15365 Port --enable-checking=all to Fedora 14 x86-64.
15366 * charset.c (syms_of_charset): Also account for glibc malloc's
15367 internal overhead when calculating the initial malloc maximum.
15369 Port --enable-checking=all to Fedora 14 x86.
15370 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15372 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15373 (overrun_check_realloc, overrun_check_free):
15374 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15375 That way, xmalloc returns a properly-aligned pointer even if
15376 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15377 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15378 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15379 into account when calculating the initial malloc maximum.
15380 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15381 Move here from alloc.c, so that charset.c can use it too.
15382 Properly align; the old code wasn't right for common 32-bit hosts
15383 when configured with --enable-checking=all.
15384 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15385 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15387 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15389 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15392 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15394 * xdisp.c (compute_display_string_end): If there's no display
15395 string at CHARPOS, return -1.
15397 * bidi.c (bidi_fetch_char): When compute_display_string_end
15398 returns a negative value, treat the character as a normal
15399 character not covered by a display string. (Bug#9624)
15401 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15403 * lread.c (Fread_from_string): Fix typo in docstring.
15405 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15407 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15408 newline, reseat the iterator instead of bidi-iterating there one
15409 character at a time. (Bug#9610)
15410 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15411 TO_CHARPOS if the bidi iterator is at base embedding level.
15413 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15415 * lread.c (readevalloop): Use correct code for NBSP.
15416 (read1): Likewise. (Bug#9608)
15418 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15420 * dbusbind.c (Fdbus_register_signal): When service is not
15421 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15423 2011-09-25 Glenn Morris <rgm@gnu.org>
15425 * buffer.c (truncate-lines): Doc fix.
15427 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15429 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15430 (Fset_window_next_buffers): Doc fix.
15432 2011-09-24 Glenn Morris <rgm@gnu.org>
15434 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15436 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15438 Fix minor problems found by static checking.
15439 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15440 * indent.c (Fvertical_motion): Fix == vs = typo.
15442 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15444 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15445 Default value is now t. Doc fix.
15447 * indent.c (Fvertical_motion): Compute and apply the overshoot
15448 logic when moving up, not only when moving down. Fix the
15449 confusing name and values of the it_overshoot_expected variable;
15450 logic changes accordingly. (Bug#9254) (Bug#9549)
15452 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15453 CHARPOS is covered by a display string which includes newlines.
15454 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15455 is covered by a display string with embedded newlines.
15457 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15459 * dbusbind.c (Fdbus_register_signal): Add match rule to
15460 Vdbus_registered_objects_table. (Bug#9581)
15461 (Fdbus_register_method, Vdbus_registered_objects_table):
15464 2011-09-24 Jim Meyering <meyering@redhat.com>
15466 do not ignore write error for any output size
15467 The previous change was incomplete.
15468 While it makes emacs --batch detect the vast majority of stdout
15469 write failures, errors were still ignored whenever the output size is
15470 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15471 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15472 && echo FAIL: ignored write error
15473 FAIL: ignored write error
15474 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15475 && echo FAIL: ignored write error
15476 FAIL: ignored write error
15477 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15479 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15481 * emacs.c (Fkill_emacs): In noninteractive mode exit
15482 non-successfully if a write error occurred on stdout. (Bug#9574)
15484 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15486 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15489 * dispextern.h (struct it): Update the comment documenting what
15492 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15494 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15495 a display string, extend search for cursor position to end of row.
15496 (find_row_edges): If the row ends in a newline from a display
15497 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15498 Handle the case of a display string with multiple newlines.
15499 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15500 non-empty line. Fixes confusing cursor motion with arrow keys at
15501 the beginning of a line that starts with whitespace.
15503 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15505 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15508 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15510 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15511 boolean (Bug#9154).
15513 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15515 * xdisp.c (display_line): Record maximum and minimum buffer
15516 positions even if no glyphs were produced (e.g., by a zero-width
15517 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15518 buffer positions that will be removed from the glyph row because
15520 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15521 column is beyond frame width: don't subtract 1 "pixel" when
15522 computing width of the stretch.
15523 (reseat_at_next_visible_line_start): Undo the change made on
15524 2011-09-17 that saved paragraph information and restored it after
15525 the call to `reseat'. (Bug#9545)
15527 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15529 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15530 and turn window cursor on if cleared (Bug#9415).
15532 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15534 * search.c (boyer_moore): Take unibyte characters from pattern
15535 literally. (Bug#9458)
15537 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15539 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15541 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15543 Fix minor problem found by static checking.
15544 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15545 initialized, to pacify gcc -Wuninitialized.
15547 * fileio.c: Report proper errno when syscall falls.
15548 (Finsert_file_contents): Save and restore errno,
15549 so that report_file_error outputs the correct diagnostic.
15550 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15552 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15554 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15556 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15558 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15559 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15561 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15563 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15564 about the current paragraph and restore it after the call to reseat.
15566 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15567 (bidi_find_paragraph_start): Search back for paragraph beginning
15568 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15569 (bidi_move_to_visually_next): Only trigger paragraph-related
15570 computations when the last character is a newline or at EOB, not
15571 just any NEUTRAL_B. (Bug#9470)
15573 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15574 truncated lines if point is covered by a display string. (Bug#9524)
15576 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15578 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15579 (cons_to_x_long): New function.
15580 (lisp_data_to_selection_data): Use it. Correct the test for
15581 short-versus-long data; it was negated. Break out of vector
15582 loop, for efficiency, when a long datum is discovered.
15584 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15586 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15588 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15590 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15591 GCC PR/17406) by declaring this function with external scope.
15593 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15595 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15596 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15598 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15600 * editfns.c (Fformat): Correctly handle text properties on "%%".
15602 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15604 * xterm.c (x_draw_composite_glyph_string_foreground):
15605 * w32term.c (x_draw_composite_glyph_string_foreground):
15606 * term.c (encode_terminal_code):
15607 * composite.c (composition_update_it, get_composition_id):
15608 * xdisp.c (get_next_display_element)
15609 (fill_composite_glyph_string): Add comments about special meaning
15610 of TAB characters in a composition.
15612 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15614 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15615 This occurs when processing a multibyte format.
15616 Problem reported by Wolfgang Jenker.
15618 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15620 * xdisp.c (try_cursor_movement): Only check for exact match if
15621 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15623 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15625 Remove unused external symbols.
15626 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15627 * xdisp.c (calc_pixel_width_or_height): Now static.
15628 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15629 * indent.c (check_display_width):
15630 * w32term.c: Fix comment to match code.
15631 * xterm.c, xterm.h (x_catching_errors): Remove.
15633 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15635 * xselect.c: Use signed conversions more consistently (Bug#9498).
15636 (selection_data_to_lisp_data): Assume incoming selection data are
15637 signed integers, not unsigned. This is to be consistent with
15638 outgoing selection data, which was modified to use signed integers
15639 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15640 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15641 expects long, not unsigned long.
15643 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15645 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15646 computation of loop end. Reported by Johan Bockgård
15649 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15651 * frame.c (Fother_visible_frames_p): Function deleted.
15653 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15655 * indent.c (compute_motion): Process display vector front to back
15656 rather than the other way around. (Bug#2496)
15658 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15660 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15662 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15664 * minibuf.c (Fread_from_minibuffer): Doc fix.
15666 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15668 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15669 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15671 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15673 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15674 value for non-existent files.
15676 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15678 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15679 set its "size" to -1. This will set the modtime_size field of
15680 the corresponding buffer to -1, which is what
15681 verify-visited-file-modtime expects for files that do not exist.
15684 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15686 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15688 * lisp.h: ... from here. push_key_description is no longer
15689 defined in keyboard.c, so its declaration should not be in
15690 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15691 logically belongs with push_key_description.
15693 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15695 * buffer.h: Include <sys/types.h> instead of <time.h>.
15696 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15697 Problem reported by Herbert J. Skuhra.
15699 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15701 * xml.c (parse_region): Make the parsing work for
15702 non-comment-starting XML files again (bug#9144).
15704 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15706 * image.c (gif_load): Fix calculation of bottom and right corner.
15709 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15711 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15712 redisplay in small windows.
15714 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15716 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15718 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15720 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15721 Operate on live windows only.
15723 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15725 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15727 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15729 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15730 only under bidi iteration.
15732 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15734 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15736 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15738 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15739 Without this fix, the command to link temacs failed due to an
15740 undefined symbol __builtin_isnan. This is because
15741 /usr/include/iso/math_c99.h #defines isnan(x) to
15742 __builtin_isnan(x), but the bundled gcc, which identifies itself
15743 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15745 * floatfns.c (isnan): #undef, and then #define to a clone of
15747 (Fisnan): Always define, since it's always available now.
15748 (syms_of_floatfns): Always define isnan at the Lisp level.
15750 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15752 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15754 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15756 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15757 The previous code assumed that file offsets (off_t values) fit in
15758 EMACS_INT variables, which is not true on typical 32-bit hosts.
15759 The code messed up by falsely reporting buffer overflow in cases
15760 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15761 when "big" contains more than 2**29 bytes, even though this
15762 inserts just one byte and does not overflow the buffer.
15763 (Finsert_file_contents): Store file offsets as off_t
15764 values, not as EMACS_INT values. Check for overflow when
15765 converting between EMACS_INT and off_t. When checking for
15766 buffer overflow or for overlap, take the offsets into account.
15767 Don't use EMACS_INT for small values where int suffices.
15768 When checking for overlap, fix a typo: ZV was used where
15769 ZV_BYTE was intended.
15770 (Fwrite_region): Don't assume off_t fits into 'long'.
15771 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15773 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15775 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15777 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15779 sprintf-related integer and memory overflow issues (Bug#9412).
15781 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15782 (esprintf, exprintf, evxprintf): New functions.
15783 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15784 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15785 (modify_event_symbol): Do not assume that the length of
15786 name_alist_or_stem is safe to alloca and fits in int.
15787 (Fexecute_extended_command): Likewise for function name and binding.
15788 (Frecursion_depth): Wrap around reliably on integer overflow.
15789 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15790 since some callers pass EMACS_INT values.
15791 (Fsingle_key_description): Don't crash if symbol name contains more
15792 than MAX_ALLOCA bytes.
15793 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15794 (get_minibuffer): Arg is now EMACS_INT, not int.
15795 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15796 (esprintf, exprintf, evxprintf): New decls.
15797 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15799 * dbusbind.c (signature_cat): New function.
15800 (xd_signature, Fdbus_register_signal):
15801 Do not overrun buffer; instead, report string overflow.
15803 * dispnew.c (add_window_display_history): Don't overrun buffer.
15804 Truncate instead; this is OK since it's just a log.
15806 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15807 even if the time zone offset is outlandishly large.
15808 Don't mishandle offset == INT_MIN.
15810 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15811 when creating daemon; the previous buffer-overflow check was incorrect.
15813 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15814 which has the guts of the old verror function.
15816 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15817 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15819 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15820 (font_unparse_xlfd): Don't blindly alloca long strings.
15821 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15822 fits in int, when using sprintf. Use single snprintf to count
15823 length of string rather than counting it via multiple sprintfs;
15824 that's simpler and more reliable.
15825 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15826 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15827 sprintf, in case result does not fit in int.
15829 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15830 (fontset_from_font): Print it.
15832 * frame.c (tty_frame_count): Now printmax_t, not int.
15833 (make_terminal_frame, set_term_frame_name): Print it.
15834 (x_report_frame_params): In X, window IDs are unsigned long,
15835 not signed long, so print them as unsigned.
15836 (validate_x_resource_name): Check for implausibly long names,
15837 and don't assume name length fits in 'int'.
15838 (x_get_resource_string): Don't blindly alloca invocation name;
15839 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15842 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15843 (xg_check_special_colors, xg_set_geometry):
15844 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15846 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15847 Use esprintf, not sprintf, in case result does not fit in int.
15849 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15850 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15851 it as a large positive number.
15852 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15853 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15855 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15856 in case result does not fit in int.
15858 * print.c (float_to_string): Detect width overflow more reliably.
15859 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15860 buffer overrun. Don't assume list length fits in 'int'. Treat
15861 print length of 0 as 0, not as infinity; to be consistent with other
15862 uses of print length in this function. Don't overflow print length
15863 index. Don't assume hash table size fits in 'long', or that
15864 vectorlike size fits in 'unsigned long'.
15866 * process.c (make_process): Use printmax_t, not int, to format
15867 process-name gensyms.
15869 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15871 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15872 to avoid potential buffer overrun.
15874 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15875 if X resource line is longer than 512 bytes.
15877 * xfns.c (x_window): Make sprintf buffer a bit bigger
15878 to avoid potential buffer overrun.
15880 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15882 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15884 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15886 Integer overflow fixes for scrolling, etc.
15887 Without these, Emacs silently mishandles large integers sometimes.
15888 For example, "C-u 4294967297 M-x recenter" was treated as if
15889 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15891 * xdisp.c (try_window_id): Check Emacs fixnum range before
15892 converting to 'int'.
15894 * window.c (window_scroll_line_based, Frecenter):
15895 Check that an Emacs fixnum is in range before assigning it to 'int'.
15896 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15897 values converted from Emacs fixnums.
15898 (Frecenter): Don't wrap around a line count if it is out of 'int'
15899 range; instead, treat it as an extreme value.
15900 (Fset_window_configuration, compare_window_configurations):
15901 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15903 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15904 that can exceed INT_MAX. Check that EMACS_INT value is in range
15905 before assigning it to the (possibly-narrower) index.
15906 (match_limit): Don't assume that a fixnum can fit in 'int'.
15908 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15911 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15912 (Fvertical_motion): Don't wrap around LINES values that don't fit
15913 in 'int'. Instead, treat them as extreme values. This is good
15914 enough for windows, which can't have more than INT_MAX lines anyway.
15916 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15918 * Require libxml/parser.h to avoid compilation warning.
15920 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15922 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15923 since this reportedly can destroy thread storage.
15925 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15927 * syntax.c (find_defun_start): Update all cache variables if
15928 exiting early (Bug#9401).
15930 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15932 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15934 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15935 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15936 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15938 * term.c (tty_append_glyph): New function.
15939 (produce_stretch_glyph): Static function and its prototype deleted.
15941 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15944 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15946 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15947 when checking :margin (Bug#9390).
15948 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15949 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15950 so that the name doesn't mislead. All uses changed.
15952 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15954 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15957 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15959 * xdisp.c (move_it_to): Don't bail out early when reaching
15960 position beyond to_charpos, if we are scanning backwards.
15961 (move_it_vertically_backward): When DY == 0, make sure we get to
15962 the first character in the line after the newline.
15964 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15966 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15967 (ccl_driver): Do not generate an out-of-range pointer.
15968 (Fccl_execute_on_string): Remove unnecessary check for
15969 integer overflow, noted by Stefan Monnier in
15970 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15971 Remove a FIXME that didn't need fixing.
15972 Simplify the newly-introduced buffer reallocation code.
15974 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15976 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15978 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15980 Integer and memory overflow issues (Bug#9196).
15982 * doc.c (get_doc_string): Rework so that
15983 get_doc_string_buffer_size is the actual buffer size, rather than
15984 being 1 less than the actual buffer size; this makes xpalloc more
15987 * image.c (x_allocate_bitmap_record, cache_image):
15988 * xselect.c (Fx_register_dnd_atom):
15989 Simplify previous changes by using xpalloc.
15991 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15992 since either will do and ptrdiff_t is convenient with xpalloc.
15994 * charset.c (charset_table_size)
15995 (struct charset_sort_data.priority): Now ptrdiff_t.
15996 (charset_compare): Don't overflow if priorities differ greatly.
15997 (Fsort_charsets): Don't assume list length fits in int.
15998 Check for size-calculation overflow when allocating sort data.
15999 (syms_of_charset): Allocate an initial charset table that is
16000 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16002 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16004 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16005 The actual value is always <= INT_MAX, and leaving it unsigned made
16006 overflow checking harder.
16008 * dispextern.h (struct glyph_matrix.rows_allocated)
16009 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16010 with xpalloc. The values are still always <= INT_MAX.
16012 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16014 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16015 (SAFE_NALLOCA): New macro.
16017 * region-cache.c (struct boundary.pos, find_cache_boundary)
16018 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16019 (set_cache_region, invalidate_region_cache)
16020 (revalidate_region_cache, know_region_cache, region_cache_forward)
16021 (region_cache_backward, pp_cache):
16022 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16023 so that ptrdiff_t * can be passed to xpalloc.
16024 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,

16043 because xmalloc/xrealloc may not return.
16044 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16045 now that we have proper integer overflow checking.
16046 (record_overlay_string, overlay_strings): Catch overflows when
16047 calculating size of overlay_str_buf.
16049 * callproc.c (Fcall_process): Check for size overflow when
16050 calculating size of args2.
16051 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

16053 require adding more-complicated checks.
16055 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16056 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

16096 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16098 * emacs.c (main): Do not reallocate argv, since there is a null at
16099 the end that can be overwritten, and this way there's no need to
16100 worry about size-calculation overflow.
16101 (sort_args): Check for size-calculation overflow.
16103 * eval.c (init_eval_once, grow_specpdl): Don't update size until

16109 Check for integer overflow.
16110 (x_set_alpha): Do not assume XINT fits in int.
16112 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16113 This is for the members text_lines, text_cols, total_lines, total_cols,
16114 where the system imposes an 'int' limit.
16116 * fringe.c (Fdefine_fringe_bitmap):
16117 Don't update size until alloc works.

16122 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16123 Check for size-calculation overflow.
16124 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16125 do, as we prefer signed integers.
16126 (id_to_widget.max_size, id_to_widget.used)
16127 (xg_store_widget_in_map, xg_remove_widget_from_map)

16132 * gtkutil.h: Change prototypes to match the above.
16134 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

16181 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16182 for command line length. Do not attempt to address one before the
16183 beginning of an array, as that's not portable.

16218 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16219 sizes, since they can exceed INT_MAX in size. Check for size

16230 (X_LONG_MIN): New macros.
16231 Use them to make the following changes clearer.
16232 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16233 This change doesn't affect the value now, but it may help remind
16234 future maintainers not to raise the value too much later.
16235 (SELECTION_QUANTUM): Remove, replacing with ...
16236 (selection_quantum): ... new function, which avoids overflow.
16238 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16239 assumption that selection length fits in 'int'.

16256 Don't store size until memory allocation succeeds.
16257 (x_get_window_property): Plug memory leak on memory exhaustion.
16258 Don't double-block input; malloc is safe here. Don't assume 2**34
16259 - 4 fits in unsigned long. Add an xassert to check
16260 XGetWindowProperty overflow. Be more careful about overflow
16261 calculations, and distinguish size from memory overflow better.
16262 (receive_incremental_selection): When tracing, don't assume
16263 unsigned int is less than INT_MAX.
16264 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16267 in the range -65535 through -1 fit in an X unsigned short.
16268 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16269 result parameters unless successful. Rely on cons_to_unsigned
16270 to report problems with elements; the old code wasn't right anyway.
16271 (x_check_property_data): Check for int overflow; we cannot use
16272 a wider type due to X limits.

16305 * lisp.h (hash_lookup, hash_put):
16306 * minibuf.c (Ftest_completion):
16307 Use ptrdiff_t for hash table indexes, not int (which is too
16308 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16309 32-bit --with-wide-int hosts).
16311 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16312 Add a FIXME comment about memory leaks.

16320 with outlandish widths.
16321 * character.h (sanitize_tab_width): Rename from sanitize_width,
16322 now that we have two such functions. All uses changed.

16341 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16342 (x_send_scroll_bar_event): Likewise. Check that the size does not
16343 exceed limits imposed by XClientMessageEvent, as well as the usual
16344 ptrdiff_t and size_t limits.
16346 * keyboard.c: Overflow, signedness and related fixes.
16347 (make_lispy_movement): Use same integer type in forward decl
16348 that is used in the definition.
16349 (read_key_sequence, keyremap_step):
16350 Change bufsize argument back to int, undoing my 2011-03-30 change.
16351 We prefer signed types, and int is wide enough here.
16352 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16353 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16354 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16355 length, not size_t. Use ptrdiff_t for index, not int.
16356 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16357 possibility of integer overflow.

16385 Prefer int to unsigned where either will do.
16386 (tiff_handler): New function, combining the cores of the
16387 old tiff_error_handler and tiff_warning_handler.
16388 This function is rewritten to use vsnprintf and thereby avoid
16389 stack buffer overflows. It uses only the features of vsnprintf
16390 that are common to both POSIX and native Microsoft.
16391 (tiff_error_handler, tiff_warning_handler): Use it.
16392 (tiff_load, gif_load, imagemagick_load_image):
16393 Don't assume :index value fits in 'int'.
16394 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16395 (imagemagick_load_image): Check that crop parameters fit into
16396 the integer types that MagickCropImage accepts. Don't assume
16397 Vimagemagick_render_type has a nonnegative value. Don't assume
16398 size_t fits in 'long'.
16399 (gs_load): Use printmax_t to print the widest integers possible.

16402 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16404 * xdisp.c (redisplay_window): Don't force window start if point

16409 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16410 the display spec is of the form `(space ...)'.
16411 (handle_display_spec): Return the value returned by
16412 handle_single_display_spec, not just 1 or zero.
16413 (handle_single_display_spec): If the display spec is of the form
16414 `(space ...)', and specifies display in the text area, return 2
16416 (try_cursor_movement): Check for the need to scroll more
16417 accurately, and prefer exact match for point under bidi.
16418 Don't advance `row' beyond the last row of the window.
16420 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16421 into disp_prop; all users changed.

16436 buffers, return left-to-right.
16437 (set_cursor_from_row): Consider candidate row a win if its glyph
16438 represents a newline and point is on that newline. Fixes cursor
16439 positioning on the newline at EOL of R2L text within L2R
16440 paragraph, and vice versa.
16441 (try_cursor_movement): Check continued rows, in addition to
16442 continuation rows. Fixes unwarranted scroll when point enters a
16443 continued line of R2L text within an L2R paragraph, or vice versa.
16444 (cursor_row_p): Consider the case of point being equal to
16445 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16446 from the end of a short line to the beginning of a continued line
16447 of R2L text within L2R paragraph.

16466 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16467 extra slot even if the purpose is char-code-property-table.
16469 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16471 * xdisp.c (redisplay_window): When computing centering_position,
16472 account for the height of the header line. (Bug#8874)
16474 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16475 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16476 candidate is selected by the mouse, and that candidate has a
16477 composed character under the mouse.
16479 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16480 coordinates reported by pos-visible-in-window-p for a composed
16481 character in column zero.
16483 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16491 composed buffer positions.
16493 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16495 * image.c (gif_load): Don't assume that each subimage has the same
16496 dimensions as the base image. Handle disposal method that is
16497 "undefined" by the gif spec (Bug#9335).

16507 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16508 from an Org mode buffer to a Speedbar frame.
16510 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16511 a composition, take its buffer position from IT->cmp_it.charpos.
16512 Fixes cursor positioning at the beginning of a line that begins
16513 with a composed character.
16515 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16517 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16518 character bidirectional type, use STRONG_L instead. Fixes crashes
16519 in a buffer produced by `describe-categories'.
16521 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16522 members before the level stack, so they would be saved and
16523 restored when copying iterator state. Fixes incorrect reordering
16524 around TABs covered by display properties.
16526 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16528 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16534 Remove unnecessary aborts (Bug#9081).
16536 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16538 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16539 has no `load' handler, try opening the file locally. (Bug#9311)
16541 2011-08-16 Ken Brown <kbrown@cornell.edu>
16543 * gmalloc.c: Expand comment.
16545 2011-08-16 Eli Zaretskii <eliz@gnu.org>

16561 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16562 in the static heap.
16563 [CYGWIN] (special_realloc): New function.
16564 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

16596 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16598 * xdisp.c (move_it_in_display_line_to): Don't invoke
16599 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16600 ppos_it. Fixes vertical cursor motion when line beginning is
16601 covered by an image. (Bug#9296)
16603 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16605 * nsterm.h (ns_run_ascript): Declare.

16609 (ns_run_ascript): New function.
16610 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16611 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16612 the event loop. Get status from as_status (Bug#7276).
16614 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16615 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16616 the event loop (Bug#7276).
16618 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16620 * gnutls.c (QCgnutls_bootprop_priority)

16622 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16623 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

16642 (Fnetwork_interface_list): Allocate in increments of bytes instead
16643 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16644 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16646 (struct ifflag_def): notrailers is smart on OSX.
16647 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16648 Get hardware address with getifaddrs if available.
16650 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16652 * xdisp.c (iterate_out_of_display_property): xassert that
16653 IT->position is set to within IT->object's boundaries. Break from
16654 the loop as soon as EOB is reached; avoids infloops in redisplay
16655 when IT->position is set up wrongly due to some bug.
16656 Set IT->current to match the bidi iterator unconditionally.
16657 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16658 entry. Force push_it to save on the stack the current
16659 buffer/string position, to be restored by pop_it. Fix flags in
16660 the iterator structure wrt the object coming from a display
16661 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16662 properties. (Bug#9284)
16664 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16666 * fontset.c (fontset_get_font_group): Add proper type checks.

16696 2011-08-07 Juri Linkov <juri@jurta.org>
16698 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16699 to show the arg `TIME' instead of `TIMEVAL'.
16701 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16703 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16704 display property strides EOL and includes a newline, as in
16705 longlines-mode. (Bug#9254)
16706 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16707 word-wrap under bidirectional display. (Bug#9224)
16709 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16710 is non-zero, even if the data buffer is NULL. Fixes a crash in
16711 vertical-motion with longlines-mode. (Bug#9254)
16713 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16715 * bidi.c <bidi_cache_total_alloc>: Now static.

16718 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16721 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16722 amount allocated this far in `bidi_cache_total_alloc'.
16723 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16724 non-zero, only free the data buffer without restoring the cache
16725 contents. All callers changed.
16727 * dispextern.h (bidi_unshelve_cache): Update prototype.
16729 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16730 (move_it_in_display_line, move_it_to)
16731 (move_it_vertically_backward, move_it_by_lines): Replace the call
16732 to xfree to an equivalent call to bidi_unshelve_cache.
16733 (move_it_in_display_line_to): Fix logic of returning
16734 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16736 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16738 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16739 came from a string character with a `cursor' property. (Bug#9229)

16753 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16755 * xterm.c (x_find_topmost_parent): New function.
16756 (x_set_frame_alpha): Find topmost parent window with
16757 x_find_topmost_parent and set the property there also (bug#9181).
16758 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16760 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

16786 for a display string or property. If found, set DISP_PROP_P
16789 * bidi.c (bidi_fetch_char): Accept an additional argument
16790 DISP_PROP_P, and pass it to compute_display_string_pos.
16791 Only handle text covered by a display string if DISP_PROP_P is returned
16792 non-zero. All callers of bidi_fetch_char changed.
16794 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

16820 * regex.c (re_comp): Protoize.
16821 (re_exec): Fix return type.
16822 (regexec): Fix type of `ret'. (Bug#9203)
16824 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16826 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16827 This is needed if max-image-size is a floating-point number.
16829 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16831 * print.c (print_object): Print empty symbol as ##.

16876 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16878 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16879 Without this fix, if a signal arrives just after memory fills up,
16880 'malloc' might be invoked reentrantly.
16882 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16883 In other words, assume that every image size is allowed, on non-X
16884 hosts. This assumption is probably wrong, but it lets Emacs compile.
16886 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16888 * regex.c (re_iswctype): Convert return values to boolean.

16907 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16908 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16909 (bidi_find_other_level_edge):
16910 Use ptrdiff_t instead of EMACS_INT where either will do.
16911 This works better on 32-bit hosts configured --with-wide-int.
16912 (bidi_cache_ensure_space): Check for size-calculation overflow.
16913 Use % rather than repeated addition, for better worst-case speed.
16914 Don't set bidi_cache_size until after xrealloc returns, because it
16916 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16917 (bidi_cache_ensure_space): Also check that the bidi cache size
16918 does not exceed that of the largest Lisp string or buffer. See Eli
16919 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16921 * alloc.c (__malloc_size_t): Remove.
16922 All uses replaced by size_t. See Andreas Schwab's note
16923 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16925 * image.c: Improve checking for integer overflow.
16926 (check_image_size): Assume that f is nonnull, since
16927 it is always nonnull in practice. This is one less thing to
16928 worry about when checking for integer overflow later.
16929 (x_check_image_size): New function, which checks for integer
16930 overflow issues inside X.
16931 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16932 This removes the need for a memory_full check.
16933 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16934 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16935 (xbm_read_bitmap_data): Change locals back to 'int', since
16936 their values must fit in 'int'.
16937 (xpm_load_image, png_load, tiff_load):
16938 Invoke x_create_x_image_and_pixmap earlier,
16939 to avoid much needless work if the image is too large.
16940 (tiff_load): Treat overly large images as if
16941 x_create_x_image_and_pixmap failed, not as malloc failures.
16942 (gs_load): Use x_check_image_size.
16944 * gtkutil.c: Omit integer casts.
16945 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16946 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16948 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16950 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16951 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16952 would wrongly return t on a 64-bit host.
16954 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16955 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16956 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16957 and therefore cause GCC to emit a bogus diagnostic in some cases.
16959 * image.c: Integer signedness and overflow and related fixes.
16960 This is not an exhaustive set of fixes, but it's time to
16961 record what I've got.
16962 (lookup_pixel_color, check_image_size): Remove redundant decls.
16963 (check_image_size): Don't assume that arbitrary EMACS_INT values
16964 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16965 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16966 (tiff_load, imagemagick_load_image):
16967 Check for overflow in size calculations.
16968 (x_create_x_image_and_pixmap): Remove unnecessary test for
16969 xmalloc returning NULL; that can't happen.
16970 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16971 (xpm_color_bucket): Use better integer hashing function.
16972 (xpm_cache_color): Don't possibly over-allocate memory.
16973 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16974 (gif_memory_source):
16975 Use ptrdiff_t, not int or size_t, to record sizes.
16976 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16977 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16978 either works, as we prefer signed integers.
16979 (tiff_read_from_memory, tiff_write_from_memory):
16980 Return tsize_t, not size_t, since that's what the TIFF API wants.
16981 (tiff_read_from_memory): Don't fail simply because the read would
16982 go past EOF; instead, return a short read.
16983 (tiff_load): Omit no-longer-needed casts.
16984 (Fimagemagick_types): Don't assume size fits into 'int'.
16986 Improve hashing quality when configured --with-wide-int.
16987 * fns.c (hash_string): New function, taken from sxhash_string.
16988 Do not discard information about ASCII character case; this
16989 discarding is no longer needed.
16990 (sxhash-string): Use it. Change sig to match it. Caller changed.
16991 * lisp.h: Declare it.
16992 * lread.c (hash_string): Remove, since we now use fns.c's version.
16993 The fns.c version returns a wider integer if --with-wide-int is
16994 specified, so this should help the quality of the hashing a bit.
16996 * emacs.c: Integer overflow minor fix.
16997 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16998 Define only if GNU_LINUX.
16999 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17001 * dispnew.c: Integer signedness and overflow fixes.
17002 Remove unnecessary forward decls, that were a maintenance hassle.
17003 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17005 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17006 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17007 (prepare_desired_row, line_draw_cost):
17008 Use int, not unsigned, where either works.
17009 (save_current_matrix, restore_current_matrix):
17010 Use ptrdiff_t, not size_t, where either works.
17011 (init_display): Check for overflow more accurately, and without
17012 relying on undefined behavior.
17014 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17015 Remove, replacing with the new symbols in lisp.h. All uses changed.
17016 * fileio.c (make_temp_name):
17017 * filelock.c (lock_file_1, lock_file):
17018 * xdisp.c (message_dolog):
17019 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17020 Use pMd etc. instead.
17021 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17022 replacing the pWIDE etc. symbols removed from editfns.c.
17024 * keyboard.h (num_input_events): Now uintmax_t.
17025 This is (very slightly) less likely to mess up due to wraparound.
17028 * buffer.c: Integer signedness fixes.
17029 (alloc_buffer_text, enlarge_buffer_text):
17030 Use ptrdiff_t rather than size_t when either will do, as we prefer
17033 * alloc.c: Integer signedness and overflow fixes.
17034 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17035 (__malloc_size_t): Default to size_t, not to int.
17036 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17037 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17038 Prefer ptrdiff_t to size_t when either would do, as we prefer
17040 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17041 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17042 Now const. Initialize with values that are in range even if char
17044 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17045 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17046 These functions do the right thing with sizes > 2**32.
17047 (check_depth): Now ptrdiff_t, not int.
17048 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17049 Adjust to new way of storing sizes. Check for size overflow bugs
17051 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17052 slightly wrong anyway, as it missed one instance of
17053 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17054 (refill_memory_reserve): Omit needless cast to size_t.
17055 (mark_object_loop_halt): Mark as externally visible.
17057 * xselect.c: Integer signedness and overflow fixes.
17058 (Fx_register_dnd_atom, x_handle_dnd_message):
17059 Use ptrdiff_t, not size_t, since we prefer signed.
17060 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17061 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17062 x_dnd_atoms_size and x_dnd_atoms_length.
17064 * doprnt.c: Prefer signed to unsigned when either works.
17066 * doprnt.c (doprnt):
17068 * xdisp.c (vmessage):
17069 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17070 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17071 prefer signed arithmetic to avoid comparison confusion.
17072 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17073 but is a bit tricky.
17075 Assume freestanding C89 headers, string.h, stdlib.h.
17076 * data.c, doprnt.c, floatfns.c, print.c:
17077 Include float.h unconditionally.
17078 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17079 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17080 * regex.c: Likewise for stddef.h, string.h.
17081 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17082 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17083 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17084 (STDC_HEADERS): Remove obsolete defines.
17085 * sysdep.c: Include limits.h unconditionally.
17087 Assume support for memcmp, memcpy, memmove, memset.
17088 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17089 * regex.c (memcmp, memcpy):
17090 Remove; we assume C89 now.
17092 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17093 (__malloc_safe_bcopy): Remove; no longer needed.
17095 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17096 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17097 well either way, and we prefer signed to unsigned.
17099 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17101 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17102 closes the connection while we're reading (bug#9182).
17104 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17106 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17107 are specified (Bug#9168).
17109 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17111 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17112 Found by GCC static checking and --with-wide-int on a 32-bit host.
17114 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17116 * xdisp.c (compute_display_string_pos): Fix logic of caching
17117 previous display string position. Initialize cached_prev_pos to
17118 -1. Fixes slow-down at the beginning of a buffer.
17120 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17122 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17123 for attrs[LFACE_FONTSET_INDEX].
17125 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17127 * xml.c (parse_region): Remove unused local
17128 that was recently introduced.
17130 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17132 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17133 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17135 * xdisp.c (move_it_in_display_line_to): Record the best matching
17136 position for TO_CHARPOS while scanning the line, and restore it on
17137 exit if none of the characters scanned was an exact match.
17138 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17139 when exact match is impossible due to invisible text, and the
17140 lines are truncated.
17142 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17144 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17147 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17149 Fix a significant slow-down of cursor motion with C-n, C-p,
17150 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17151 auto-repeat under bidi redisplay in fontified buffers.
17152 * xdisp.c (compute_stop_pos_backwards): New function.
17153 (next_element_from_buffer): Call compute_stop_pos_backwards to
17154 find a suitable prev_stop when we find ourselves before
17156 (reseat): Don't look for prev_stop, as that could mean a very long
17158 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17159 <cached_disp_overlay_modiff>: Cache for last found display string
17161 (compute_display_string_pos): Return the cached position if asked
17162 about the same buffer in the same area of character positions, and
17163 the buffer wasn't changed since the time the display string
17164 position was cached.
17166 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17168 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17169 is an integer, which is important for empty lines. (Bug#9149)
17171 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17173 * frame.c (Fmodify_frame_parameters): In tty case, update the
17174 default face if necessary (Bug#4238).
17176 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17178 * editfns.c (Fstring_to_char): No need to explain what a character
17179 is in the docstring (Bug#6576).
17181 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17183 * xml.c (parse_region): Make sure we always return a tree.
17185 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17187 * xml.c (parse_region): If a document contains only comments,
17190 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17192 * xml.c (make_dom): Return comments, too.
17194 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17197 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17198 and the surrounding thread.
17199 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17200 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17201 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17203 * s/openbsd.h (BROKEN_SIGIO): Define.
17204 * unexelf.c (unexec) [__OpenBSD__]:
17205 Don't update the .mdebug section of the Alpha COFF symbol table.
17207 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17209 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17212 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17214 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17215 This fixes some race conditions on the permissions of any newly
17218 * alloc.c (valid_pointer_p): Use pipe, not open.
17219 This fixes some permissions issues when debugging.
17221 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17222 If fchown fails to set both uid and gid, try to set just gid,
17223 as that is sometimes allowed. Adjust the file's mode to eliminate
17224 setuid or setgid bits that are inappropriate if fchown fails.
17226 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17228 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17229 to compare Lisp_Objects.
17230 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17231 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17232 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17234 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17236 * lread.c (read_integer): Unread even EOF character.
17237 (read1): Likewise. Properly record start position of symbol.
17239 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17240 symbol character follows.
17242 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17244 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17245 This works around a problem with the previous change to Fcopy_file.
17246 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17247 and without this change, GCC might complain about discarding
17248 fchown's return value.
17250 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17252 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17254 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17256 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17258 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17260 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17261 it's used from the C level.
17263 * process.c: Use the same condition for POLL_FOR_INPUT in both
17264 keyboard.c and process.c (bug#1858).
17266 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17268 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17269 (Fgnutls_boot): Use it.
17271 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17273 * doc.c (Fsubstitute_command_keys): Revert last change.
17275 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17277 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17278 quotes the next character, and doesn't affect other longer
17279 sequences (bug#8935).
17281 * lread.c (syms_of_lread): Clarify that is isn't only
17282 `eval-buffer' and `eval-defun' that's affected by
17283 `lexical-binding' (bug#8460).
17285 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17287 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17288 bidi redisplay when a line includes both an image and is truncated.
17290 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17292 Fix minor problems found by static checking.
17293 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17294 (elsz): Now a signed constant, not a size_t var. We prefer signed
17295 types to unsigned, to avoid integer comparison confusion. Without
17296 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17297 "cannot optimize loop, the loop counter may overflow", a symptom
17299 * indent.c (Fvertical_motion): Mark locals as initialized.
17300 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17302 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17304 * search.c (Fre_search_backward): Mention `case-fold-search' in
17305 all the re_search_* functions (bug#8138).
17307 * keyboard.c (Fopen_dribble_file): Document when the file is
17310 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17312 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17315 Support bidi reordering of display and overlay strings.
17316 * xdisp.c (compute_display_string_pos)
17317 (compute_display_string_end): Accept additional argument STRING.
17318 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17319 (reseat_to_string): Initialize bidi_it->string.s and
17320 bidi_it->string.schars.
17321 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17322 NULL (avoids a crash in bidi_paragraph_init).
17323 Initialize itb.string.lstring.
17324 (init_iterator): Call bidi_init_it only of a valid
17325 buffer position was specified. Initialize paragraph_embedding to
17327 (reseat_to_string): Initialize the bidi iterator.
17328 (display_string): If we need to ignore text properties of
17329 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17330 original value of -1 will not work with bidi.)
17331 (compute_display_string_pos): First arg is now struct
17332 `text_pos *'; all callers changed. Support display properties on
17334 (compute_display_string_end): Support display properties on Lisp
17336 (init_iterator, reseat_1, reseat_to_string): Initialize the
17337 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17338 when iterating on a string not from display properties).
17339 (compute_display_string_pos, compute_display_string_end):
17340 Fix calculation of the object to scan. Fixes an error when using
17342 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17343 base_level_stop; instead, set base_level_stop to BEGV.
17344 Fixes crashes in vertical-motion.
17345 (next_element_from_buffer): Improve commentary for when
17346 the iterator is before prev_stop.
17347 (init_iterator): Initialize bidi_p from the default value of
17348 bidi-display-reordering, not from buffer-local value. Use the
17349 buffer-local value only if initializing for buffer iteration.
17350 (handle_invisible_prop): Support invisible properties on strings
17351 that are being bidi-reordered.
17352 (set_iterator_to_next): Support bidi reordering of C strings and
17354 (next_element_from_string): Support bidi reordering of Lisp
17356 (handle_stop_backwards): Support Lisp strings as well.
17357 (display_string): Support display of R2L glyph rows.
17358 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17359 (init_iterator): Don't initialize it->bidi_p for strings
17361 (reseat_to_string): Initialize it->bidi_p for strings here.
17362 (next_element_from_string, next_element_from_c_string)
17363 (next_element_from_buffer): Add xassert's for correspondence
17364 between IT's object being iterated and it->bidi_it.string
17366 (face_before_or_after_it_pos): Support bidi iteration.
17367 (next_element_from_c_string): Handle the case of the first string

17822 * alloc.c (mark_buffer):
17823 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
17824 (clone_per_buffer_values): Don't assume that
17825 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
17826 This isn't true in general, and it's particularly not true
17827 if Emacs is configured with --with-wide-int.
17828 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17829 New macros, used in the buffer.c change.

17863 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
17865 Random fixes. E.g., (random) never returned negative values.
17866 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17867 subseconds part to the entropy, as that's a bit more random.
17868 Prefer signed to unsigned, since the signedness doesn't matter and
17869 in general we prefer signed. When given a limit, use a
17870 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17871 latter isn't right if USE_2_TAGS_FOR_INTS.
17872 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17873 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17875 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17877 * textprop.c (text_property_stickiness):
17878 Obey Vtext_property_default_nonsticky.

17885 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17886 This is more efficient than Ffile_directory_p and avoids a minor race.
17888 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17890 * buffer.c (Foverlay_put): Say what the return value is
17893 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17894 is a directory before asking whether to use the file name
17896 (barf_or_query_if_file_exists): Make the "File is a directory"
17897 error be more correct.
17899 * fns.c (Frequire): Remove the mention of the .gz files, since
17900 that's installation-specific, but keep the mention of
17901 `get-load-suffixes'.

17905 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17911 (syms_of_gnutls): Remove duplicate DEFSYM for
17912 Qgnutls_bootprop_verify_hostname_error, an error for
17913 Qgnutls_bootprop_verify_error (which is no longer used).
17915 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17916 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17917 Also (re)move comments that are misplaced or no longer relevant.
17919 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17921 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17980 (syms_of_keymap): Defsubr make-composed-keymap.
17981 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18018 * eval.c (struct backtrace): Simplify and port the data structure.
18019 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18020 signed bit field, as this assumption is not portable and it makes
18021 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18022 "char debug_on_exit : 1" as this is not portable either; instead,
18023 use the portable "unsigned int debug_on_exit : 1". Remove unused
18024 member evalargs. Remove obsolete comments about cc bombing out.
18026 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18245 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18246 Mark as externally visible.
18247 * dispnew.c (check_window_matrix_pointers): Now static.
18248 * dispnew.c (window_to_frame_vpos):
18249 * xfns.c (unwind_create_frame):
18250 * xterm.c (x_check_font): Remove unused local.
18251 * scroll.c (CHECK_BOUNDS):
18252 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18253 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18254 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18255 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18256 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18258 (debug_method_add): Use va_list and vsprintf rather than relying
18259 on undefined behavior with wrong number of arguments.
18260 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18261 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18262 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18263 since we're not interested in debugging glyphs with old libraries.
18264 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18265 GCC 4.6.0's static checking.
18267 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18269 Integer overflow and signedness fixes (Bug#8873).
18270 A few related buffer overrun fixes, too.
18272 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
18274 * dispextern.h (struct face.stipple):
18275 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)

18278 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18279 (x_create_bitmap_from_xpm_data):
18280 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18281 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18283 * xfaces.c (load_pixmap):
18284 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18285 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18286 (.bitmaps_last, struct x_output.icon_bitmap):
18287 Use ptrdiff_t, not int, for bitmap indexes.
18288 (x_allocate_bitmap_record): Check for size overflow.
18289 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18291 Use ptrdiff_t, not int, for overlay counts.
18292 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18293 * editfns.c (overlays_around, get_pos_property):
18294 * textprop.c (get_char_property_and_overlay):
18295 * xdisp.c (next_overlay_change, note_mouse_highlight):
18296 * xfaces.c (face_at_buffer_position):
18297 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18298 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18299 (Fnext_overlay_change, Fprevious_overlay_change)
18300 (mouse_face_overlay_overlaps, Foverlays_in):
18301 Use ptrdiff_t, not int, for sizes.
18302 (overlays_at, overlays_in): Check for size-calculation overflow.
18304 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18306 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18307 (x_session_initialize): Do not assume string length fits in int.
18309 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18310 This is unlikely, but can occur if DPI is outlandish.
18312 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18313 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18315 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18316 * xrdb.c (magic_file_p, search_magic_path):
18317 Omit last arg SUFFIX; it was always 0. All callers changed.
18318 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18320 * xfont.c (xfont_match): Avoid need for strlen.
18322 * xfns.c: Don't assume strlen fits in int.
18323 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18325 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18326 not unsigned long, as we prefer signed integers. All callers changed.
18327 Detect integer overflow in repeat count.
18328 (message_dolog): Don't assume print length fits in 39 bytes.
18329 (display_mode_element): Don't assume strlen fits in int.
18331 * termcap.c: Don't assume sizes fit in int and never overflow.
18332 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18333 (gobble_line): Check for size-calculation overflow.
18335 * minibuf.c (Fread_buffer):
18336 * lread.c (intern, intern_c_string):
18337 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18338 Don't assume string length fits in int.
18340 * keyboard.c (parse_tool_bar_item):
18341 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18343 * font.c: Don't assume string length fits in int.
18344 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18345 Use ptrdiff_t, not int.
18346 (font_intern_prop): Don't assume string length fits in int.
18347 Don't assume integer property fits in fixnum.
18348 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18350 * filelock.c: Fix some buffer overrun and integer overflow issues.
18351 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18352 Reformulate so as not to need the command string.
18353 Invoke gzip -cd rather than gunzip, as it's more portable.
18354 (lock_info_type, lock_file_1, lock_file):
18355 Don't assume pid_t and time_t fit in unsigned long.
18356 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18357 (current_lock_owner): Prefer signed type for sizes.
18358 Use memcpy, not strncpy, where memcpy is what is really wanted.
18359 Don't assume (via atoi) that time_t and pid_t fit in int.
18360 Check for time_t and/or pid_t out of range, e.g., via a network share.
18361 Don't alloca where an auto var works fine.
18363 * fileio.c: Fix some integer overflow issues.
18364 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18365 Don't assume string length fits in int.
18366 (directory_file_name): Don't assume string length fits in long.
18367 (make_temp_name): Don't assume pid fits in int, or that its print
18368 length is less than 20.
18370 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18372 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18374 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18376 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18377 We prefer signed integers, even for size calculations.
18379 * emacs.c: Don't assume string length fits in 'int'.
18380 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18381 (main): Don't invoke strlen when not needed.
18383 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18384 (XD_DEBUG_MESSAGE): Don't waste a byte.
18386 * callproc.c (getenv_internal_1, getenv_internal)
18387 (Fgetenv_internal):
18388 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18390 * lread.c (invalid_syntax): Omit length argument.
18391 All uses changed. This doesn't fix a bug, but it simplifies the
18392 code away from its former Hollerith-constant appearance, and it's
18393 one less 'int' to worry about when looking at integer-overflow issues.
18394 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18396 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18397 This didn't break anything, but it didn't help either.
18398 It's confusing to put a bogus integer in a place where the actual
18399 value does not matter.
18400 (LIST_END_P): Remove unused macro and its bogus comment.
18401 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18403 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18404 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18406 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18407 We prefer signed types, and the value cannot exceed the EMACS_INT
18408 range anyway (because otherwise the length would not be representable).
18409 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18410 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18411 This avoids a GCC warning when WIDE_EMACS_INT.
18413 * indent.c (sane_tab_width): New function.
18414 (current_column, scan_for_column, Findent_to, position_indentation)
18415 (compute_motion): Use it. This is just for clarity.
18416 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18418 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18420 * lisp.h (lint_assume): New macro.
18421 * composite.c (composition_gstring_put_cache):
18422 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18424 * editfns.c, insdel.c:
18425 Omit unnecessary forward decls, to simplify future changes.
18427 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18429 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18431 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18432 Use much-faster test for byte-length change.
18433 Don't assume string byte-length fits in 'int'.
18434 Check that character arg fits in 'int'.
18435 (mapcar1): Declare byte as byte, for clarity.
18437 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18439 * fns.c (concat): Catch string overflow earlier.
18440 Do not rely on integer wraparound.
18442 * dispextern.h (struct it.overlay_strings_charpos)
18443 (struct it.selective): Now EMACS_INT, not int.
18444 * xdisp.c (forward_to_next_line_start)
18445 (back_to_previous_visible_line_start)
18446 (reseat_at_next_visible_line_start, next_element_from_buffer):
18447 Don't arbitrarily truncate the value of 'selective' to int.
18449 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18451 * composite.c: Don't truncate sizes to 'int'.
18452 (composition_gstring_p, composition_reseat_it)
18453 (composition_adjust_point): Use EMACS_INT, not int.
18454 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18455 not EMACS_UINT, for indexes.
18457 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18459 * buffer.c: Include <verify.h>.
18460 (struct sortvec.priority, struct sortstr.priority):
18461 Now EMACS_INT, not int.
18462 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18463 (struct sortstr.size, record_overlay_string)
18464 (struct sortstrlist.size, struct sortlist.used):
18465 Don't truncate size to int.
18466 (record_overlay_string): Check for size-calculation overflow.
18467 (init_buffer_once): Check at compile-time, not run-time.
18469 2011-06-22 Jim Meyering <meyering@redhat.com>
18471 Don't leak an XBM-image-sized buffer
18472 * image.c (xbm_load): Free the image buffer after using it.
18474 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18477 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18478 that Sun C diagnosed.
18479 * fns.c (secure_hash): Fix pointer signedness issue.
18480 * intervals.c (static_offset_intervals): New function.
18481 (offset_intervals): Use it.
18483 2011-06-21 Leo Liu <sdl.web@gmail.com>
18486 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18489 * fns.c (secure_hash): Rename from crypto_hash_function and change
18490 the first arg to accept symbols.
18491 (Fsecure_hash): New primitive.
18492 (syms_of_fns): New symbols.
18494 2011-06-20 Deniz Dogan <deniz@dogan.se>
18496 * process.c (Fset_process_buffer): Clarify return value in
18499 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18501 * dispnew.c (add_window_display_history): Use BVAR.
18503 * xdisp.c (debug_method_add): Use BVAR.
18504 (check_window_end, dump_glyph_matrix, dump_glyph)
18505 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18507 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18510 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18511 check till after the cache is created in init_frame_faces.
18513 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18515 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18517 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18519 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18520 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18521 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18523 Improve buffer-overflow checking (Bug#8873).
18524 * fileio.c (Finsert_file_contents):
18525 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18526 Remove the old (too-loose) buffer overflow checks.
18527 They weren't needed, since make_gap checks for buffer overflow.
18528 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18529 The old code merely checked for Emacs fixnum overflow, and relied
18530 on undefined (wraparound) behavior. The new code avoids undefined
18531 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18533 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18534 Tune. Don't use wider integers than needed. Don't use alloca.
18535 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18537 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18539 * insdel.c, lisp.h (buffer_overflow): New function.
18540 (insert_from_buffer_1, replace_range, replace_range_2):
18541 * insdel.c (make_gap_larger):
18542 * editfns.c (Finsert_char):
18543 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18545 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18547 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18549 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18551 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18552 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18554 * fileio.c: Don't assume EMACS_INT fits in off_t.
18555 (emacs_lseek): New static function.
18556 (Finsert_file_contents, Fwrite_region): Use it.
18557 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18559 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18561 * fns.c: Don't overflow int when computing a list length.
18562 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18563 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18564 truncation on 64-bit hosts. Check for QUIT every
18565 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18566 faster and is responsive enough.
18567 (Flength): Report an error instead of overflowing an integer.
18568 (Fsafe_length): Return a float if the value is not representable
18569 as a fixnum. This shouldn't happen except in contrived situations.
18570 (Fnthcdr, Fsort): Don't assume list length fits in int.
18571 (Fcopy_sequence): Don't assume vector length fits in int.
18573 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18574 (header_size, word_size): New constants.
18575 (allocate_vectorlike): Don't check size overflow here.
18576 (allocate_vector): Check it here instead, since this is the only
18577 caller of allocate_vectorlike that could cause overflow.
18578 Check that the new vector's length is representable as a fixnum.
18580 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18581 The previous code was bogus. For example, next_almost_prime (32)
18582 returned 39, which is undesirable as it is a multiple of 3; and
18583 next_almost_prime (24) returned 25, which is a multiple of 5 so
18584 why was the code bothering to check for multiples of 7?
18586 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18588 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18590 Variadic C functions now count arguments with ptrdiff_t.
18591 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18592 Back then I didn't know that the Emacs coding style prefers signed int.
18593 Also, in the meantime I found a few more instances where arguments
18594 were being counted with int, which may truncate counts on 64-bit
18595 machines, or EMACS_INT, which may be unnecessarily wide.
18596 * lisp.h (struct Lisp_Subr.function.aMANY)
18597 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18598 Arg counts are now ptrdiff_t, not size_t.
18599 All variadic functions and their callers changed accordingly.
18600 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18601 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18602 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18603 * callint.c (Fcall_interactively): Check arg count for overflow,
18604 to avoid potential buffer overrun. Use signed char, not 'int',
18605 for 'varies' array, so that we needn't bother to check its size
18606 calculation for overflow.
18607 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18608 * eval.c (apply_lambda):
18609 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18610 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18611 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18613 * callint.c (Fcall_interactively): Don't use index var as event count.
18615 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18616 * mem-limits.h (SIZE): Remove; no longer used.
18618 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18620 Remove unnecessary casts.
18621 * xterm.c (x_term_init):
18622 * xfns.c (x_set_border_pixel):
18623 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18624 These aren't needed now that we assume ANSI C.
18626 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18627 It's more likely to cause problems (due to unsigned overflow)
18630 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18632 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18634 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18636 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18638 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18640 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18642 GLYPH_CODE_FACE returns EMACS_INT, not int.
18643 * dispextern.h (merge_faces):
18644 * xfaces.c (merge_faces):
18645 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18646 Don't assume EMACS_INT fits in int.
18648 * character.h (CHAR_VALID_P): Remove unused parameter.
18649 * fontset.c, lisp.h, xdisp.c: All uses changed.
18651 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18653 * fns.c (concat): Minor tuning based on overflow analysis.
18654 This doesn't fix any bugs. Use int to hold character, instead
18655 of constantly refetching from Emacs object. Use XFASTINT, not
18656 XINT, for value known to be a character. Don't bother comparing
18657 a single byte to 0400, as it's always less.
18659 * floatfns.c (Fexpt):
18660 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18662 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18665 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18667 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18668 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18669 incorrectly succeed when S was a string, because 4294967386 was
18670 truncated before it was used.
18672 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18673 Otherwise, an out-of-range integer could cause undefined behavior
18676 * composite.c: Use int, not EMACS_INT, for characters.
18677 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18678 EMACS_INT, for values that are known to be in character range.
18679 This doesn't fix any bugs but is the usual style inside Emacs and
18680 may generate better code on 32-bit machines.
18682 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18683 This is for reasons similar to the recent CHAR_STRING fix.
18684 * charset.c (Fencode_char): Check that character arg is actually
18685 a character. Pass an int to ENCODE_CHAR.
18686 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18687 wider than 'int', as a compile-time check to prevent future regressions
18690 * character.c (char_string): Remove unnecessary casts.
18692 Make sure a 64-bit char is never passed to CHAR_STRING.
18693 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18694 by silently ignoring the top 32 bits, allowing some values
18695 that were far too large to be valid characters.
18696 * character.h: Include <verify.h>.
18697 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18698 arguments are no wider than unsigned, as a compile-time check
18699 to prevent future regressions in this area.
18701 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18702 (Fsubst_char_in_region):
18704 * xdisp.c (decode_mode_spec_coding):
18705 Adjust to CHAR_STRING's new requirement.
18706 * editfns.c (Finsert_char, Fsubst_char_in_region):
18707 * fns.c (concat): Check that character args are actually
18708 characters. Without this test, these functions did the wrong
18709 thing with wildly out-of-range values on 64-bit hosts.
18711 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18712 These casts should not be needed on 32-bit hosts, either.
18713 * keyboard.c (read_char):
18714 * lread.c (Fload): Remove casts to unsigned.
18716 * lisp.h (UNSIGNED_CMP): New macro.
18717 This fixes comparison bugs on 64-bit hosts.
18718 (ASCII_CHAR_P): Use it.
18719 * casefiddle.c (casify_object):
18720 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18721 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18722 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18723 * dispextern.h (FACE_FROM_ID):
18724 * keyboard.c (read_char): Use UNSIGNED_CMP.
18726 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18727 not to EMACS_INT, to avoid GCC warning.
18729 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18731 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18732 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18733 isn't needed on 32-bit machines.
18735 * buffer.c (Fgenerate_new_buffer_name):
18736 Use EMACS_INT for count, not int.
18737 (advance_to_char_boundary): Return EMACS_INT, not int.
18739 * data.c (Qcompiled_function): Now static.
18741 * window.c (window_body_lines): Now static.
18743 * image.c (gif_load): Rename local to avoid shadowing.
18745 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18746 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18747 * alloc.c (make_save_value): Integer argument is now of type
18748 ptrdiff_t, not int.
18749 (mark_object): Use ptrdiff_t, not int.
18750 * lisp.h (pD): New macro.
18751 * print.c (print_object): Use it.
18753 * alloc.c: Use EMACS_INT, not int, to count objects.
18754 (total_conses, total_markers, total_symbols, total_vector_size)
18755 (total_free_conses, total_free_markers, total_free_symbols)
18756 (total_free_floats, total_floats, total_free_intervals)
18757 (total_intervals, total_strings, total_free_strings):
18758 Now EMACS_INT, not int. All uses changed.
18759 (Fgarbage_collect): Compute overall total using a double, so that
18760 integer overflow is less likely to be a problem. Check for overflow
18761 when converting back to an integer.
18762 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18763 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18764 These were 'int' variables that could overflow on 64-bit hosts;
18765 they were never used, so remove them instead of repairing them.
18766 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18767 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18768 Previously, this ceilinged at INT_MAX, but that doesn't work on
18770 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18772 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18773 (allocate_vectorlike): Check for ptrdiff_t overflow.
18774 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18775 when a (possibly-narrower) signed value would do just as well.
18776 We prefer using signed arithmetic, to avoid comparison confusion.
18778 * alloc.c: Catch some string size overflows that we were missing.
18779 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18780 for convenience in STRING_BYTES_MAX.
18781 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18782 The definition here is exact; the one in lisp.h was approximate.
18783 (allocate_string_data): Check for string overflow. This catches
18784 some instances we weren't catching before. Also, it catches
18785 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18786 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18787 and ptrdiff_t and EMACS_INT are both 64 bits.
18789 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18790 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18791 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18793 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18795 * alloc.c (Fmake_string): Check for out-of-range init.
18797 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18799 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

18808 (style_changed_cb): Call update_theme_scrollbar_width and call
18809 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18810 all frames (Bug#8505).

18814 and height if HAVE_GTK3 (Bug#8505).
18815 (scroll_bar_width_for_theme): New variable.
18816 (update_theme_scrollbar_width): New function.
18817 (xg_get_default_scrollbar_width): Move code to

18821 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18823 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

18830 * window.c (temp_output_buffer_show): Call display_buffer with
18831 second argument Vtemp_buffer_show_specifiers and reset latter
18832 immediately after the call.
18833 (Vtemp_buffer_show_specifiers): New variable.
18834 (auto_window_vscroll_p, next_screen_context_lines)
18835 (Vscroll_preserve_screen_position): Remove leading asterisks from

19368 instead of using explicit *_CHAR codes.
19369 (bidi_resolve_explicit, bidi_resolve_weak):

19378 (bidi_level_of_next_char): Don't try to lookup the cache for the
19379 next/previous character if nothing is cached there yet, or if we
19380 were just reseat()'ed to a new position.
19382 * xdisp.c (set_cursor_from_row): Set start and stop points
19383 according to the row's direction when priming the loop that looks
19384 for the glyph on which to display cursor.

19386 (display_prop_intangible_p): Reimplement to call
19387 handle_display_spec instead of single_display_spec_intangible_p.

19398 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19399 value of a `display' property is a "replacing spec".
19400 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19401 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19402 the display property, but just return a value indicating whether
19403 the display property will replace the characters it covers.
19404 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19405 frame_window_p members of struct bidi_it.

19431 * gnutls.c: Use Emacs's memory allocators.
19432 Without this change, the gnutls library would invoke malloc etc.
19433 directly, which causes problems on non-SYNC_INPUT hosts, and which
19434 runs afoul of improving memory_full behavior. (Bug#8761)
19435 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19436 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19437 xfree instead of the default malloc, realloc, free.
19438 (Fgnutls_boot): No need to check for memory allocation failure,
19439 since xmalloc does that for us.

19464 Check for overflow in vector size calculations.
19465 * ccl.c (ccl_driver):
19466 Check for overflow when converting EMACS_INT to int.

19468 need to be updated by these changes.
19469 * fns.c (make_hash_table, maybe_resize_hash_table):
19470 Check for integer overflow with large hash tables.
19471 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19472 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19473 (SXHASH_REDUCE): New macro.
19474 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19475 Use it instead of discarding useful hash info with large hash values.
19476 (sxhash_float): New function.
19477 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19478 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19479 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19480 Rewrite to use FIXNUM_BITS, as this simplifies things.
19481 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19482 Adjust signatures to match updated version of code.
19483 (consing_since_gc): Now EMACS_INT, since a single hash table can
19484 use more than INT_MAX bytes.

19533 Make it possible to run ./temacs.
19535 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19536 syms_of_callproc does the same thing. Remove test for

19545 (Qmetadata): New var.
19546 * data.c (Qbuffer): Don't make it static.
19547 (syms_of_data): Use DEFSYM.
19549 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19551 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19552 (CCL_CODE_MIN): New macro.
19554 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19556 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19558 * eval.c (Qdebug): Now static.
19559 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19560 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19561 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19563 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19565 * image.c: Various fixes to ImageMagick code comments.
19566 (Fimagemagick_types): Doc fix.
19568 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19570 Minor fixes prompted by GCC 4.6.0 warnings.
19572 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19574 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19575 (x_clipboard_manager_save_all): Move extern decl to ...
19576 * xterm.h: ... here, so that it can be checked for consistency.
19578 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19580 * xselect.c (x_clipboard_manager_save_frame)
19581 (x_clipboard_manager_save_all): New functions.
19582 (Fx_clipboard_manager_save): Lisp function deleted.
19584 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19585 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19587 * xterm.h: Update prototype.
19589 2011-05-28 William Xu <william.xwl@gmail.com>
19591 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19592 exiting (Bug#8239).
19594 2011-05-28 Jim Meyering <meyering@redhat.com>
19596 Avoid a sign-extension bug in crypto_hash_function.
19597 * fns.c (to_uchar): Define.
19598 (crypto_hash_function): Use it to convert some newly-signed
19599 variables to unsigned, to avoid sign-extension bugs. For example,
19600 without this change, (md5 "truc") would evaluate to
19601 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19602 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19603 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19605 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19607 Integer overflow fixes.
19609 * dbusbind.c: Serial number integer overflow fixes.
19610 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19611 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19612 to hold a serial number that is too large for a fixnum.
19613 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19614 Check for serial numbers out of range. Decode any serial number
19615 that was so large that it became a float. (Bug#8722)
19617 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19618 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19619 Use XFASTINT rather than XUINT when numbers are nonnegative.
19620 (xd_append_arg, Fdbus_method_return_internal):
19621 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19622 arguments, check that Lisp number is nonnegative, rather than
19623 silently wrapping negative numbers around. (Bug#8722)
19624 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19627 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19629 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19631 ccl: Add integer overflow checks.
19632 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19633 (IN_INT_RANGE): New macros.
19634 (ccl_driver): Use them to check for integer overflow when
19635 decoding a CCL program. Many of the new checks are whether XINT (x)
19636 fits in int; it doesn't always, on 64-bit hosts. The new version
19637 doesn't catch all possible integer overflows, but it's an
19638 improvement. (Bug#8719)
19640 * alloc.c (make_event_array): Use XINT, not XUINT.
19641 There's no need for unsigned here.
19643 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19644 This follows up to the 2011-05-06 change that substituted uintptr_t
19645 for EMACS_INT. This case wasn't caught back then.
19647 Rework Fformat to avoid integer overflow issues.
19648 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19649 now (part of C89). Include <verify.h>.
19650 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19651 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19652 (Fformat): Avoid the prepass trying to compute sizes; it was only
19653 approximate and thus did not catch overflow reliably. Instead, walk
19654 through the format just once, formatting and computing sizes as we go,
19655 checking for integer overflow at every step, and allocating a larger
19656 buffer as needed. Keep track separately whether the format is
19657 multibyte. Keep only the most-recently calculated precision, rather
19658 than them all. Record whether each argument has been converted to
19659 string. Use EMACS_INT, not int, for byte and char and arg counts.
19660 Support field widths and precisions larger than INT_MAX. Avoid
19661 sprintf's undefined behavior with conversion specifications such as %#d
19662 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19663 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19664 formatting out-of-range floating point numbers with int
19665 formats. (Bug#8668)
19667 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19669 * data.c: Avoid integer truncation in expressions involving floats.
19670 * data.c: Include <intprops.h>.
19671 (arith_driver): When there's an integer overflow in an expression
19672 involving floating point, convert the integers to floating point
19673 so that the resulting value does not suffer from catastrophic
19674 integer truncation. For example, on a 64-bit host (* 4
19675 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19676 Do not rely on undefined behavior after integer overflow.
19678 merge count_size_as_multibyte, parse_str_to_multibyte
19679 * character.c, character.h (count_size_as_multibyte):
19680 Rename from parse_str_to_multibyte; all uses changed.
19681 Check for integer overflow.
19682 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19683 since it's now a duplicate of the other. This is more of
19684 a character than a buffer op, so better that it's in character.c.
19685 * fns.c, print.c: Adjust to above changes.
19687 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19689 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19691 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19693 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19694 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19695 (x_clipboard_manager_save): Now static.
19696 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19698 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19699 (crypto_hash_function): Now static.
19700 Fix pointer signedness problems. Avoid unnecessary initializations.
19702 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19704 * termhooks.h (Vselection_alist): Make it terminal-local.
19706 * terminal.c (create_terminal): Initialize it.
19708 * xselect.c: Support for clipboard managers.
19709 (Vselection_alist): Move to termhooks.h as terminal-local var.
19710 (LOCAL_SELECTION): New macro.
19711 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19712 (symbol_to_x_atom): Remove gratuitous arg.
19713 (x_handle_selection_request, lisp_data_to_selection_data)
19714 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19715 (x_own_selection, x_get_local_selection, x_convert_selection):
19716 New arg, specifying work frame. Use terminal-local Vselection_alist.
19717 (some_frame_on_display): Delete unused function.
19718 (Fx_own_selection_internal, Fx_get_selection_internal)
19719 (Fx_disown_selection_internal, Fx_selection_owner_p)
19720 (Fx_selection_exists_p): New optional frame arg.
19721 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19722 (x_handle_selection_clear): Don't treat other terminals with the
19723 same keyboard specially. Use the terminal-local Vselection_alist.
19724 (x_clear_frame_selections): Use Frun_hook_with_args.
19726 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19728 * xterm.h: Add support for those atoms.
19730 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19732 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19733 (converted_selections, conversion_fail_tag): New global variables.
19734 (x_selection_request_lisp_error): Free the above.
19735 (x_get_local_selection): Remove unnecessary code.
19736 (x_reply_selection_request): Args changed; handle arbitrary array
19737 of converted selections stored in converted_selections.
19738 Separate the XChangeProperty and SelectionNotify steps.
19739 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19740 (x_convert_selection): New function.
19741 (x_handle_selection_event): Simplify.
19742 (x_get_foreign_selection): Don't ignore incoming requests while
19743 waiting for an answer; this will fail when we implement
19744 SAVE_TARGETS, and seems unnecessary anyway.
19745 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19746 (Vx_sent_selection_functions): Doc fix.
19748 2011-05-26 Leo Liu <sdl.web@gmail.com>
19750 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19752 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19754 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19756 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19757 for fringe update if it has periodic bitmap.
19758 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19759 and fringe_bitmap_periodic_p.
19761 * fringe.c (get_fringe_bitmap_data): New function.
19762 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19763 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19764 row. Mark glyph row for fringe update if periodicity changed.
19766 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19767 for fringe update unless it has periodic bitmap.
19769 2011-05-25 Kenichi Handa <handa@m17n.org>
19771 * xdisp.c (get_next_display_element): Set correct it->face_id for
19772 a static composition.
19774 2011-05-24 Leo Liu <sdl.web@gmail.com>
19777 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19779 * fns.c (crypto_hash_function, Fsha1): New function.
19780 (Fmd5): Use crypto_hash_function.
19781 (syms_of_fns): Add Ssha1.
19783 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19785 * gnutls.c: Remove unused macros.
19786 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19787 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19788 Remove macros that are defined and never used.
19789 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19791 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19793 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19794 (Fx_get_selection_internal): Minor cleanup.
19795 (Fx_own_selection_internal): Rename arguments for consistency with
19798 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19800 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19802 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19804 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19806 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19808 * dispnew.c (scrolling_window): Don't exclude the case that the
19809 last enabled row in the desired matrix touches the bottom boundary.
19811 2011-05-21 Glenn Morris <rgm@gnu.org>
19813 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19814 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19815 and add some more files.
19817 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19819 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19820 report_file_error introduced by the change from 2011-05-07.
19822 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19824 * systime.h (Time): Define only if emacs is defined.
19825 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19826 where the include path doesn't have X11/X.h by default. See
19827 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19829 2011-05-20 Kenichi Handa <handa@m17n.org>
19831 * composite.c (find_automatic_composition): Fix previous change.
19833 2011-05-20 Glenn Morris <rgm@gnu.org>
19835 * lisp.mk: New file, split from Makefile.in.
19836 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19837 (shortlisp): Remove.
19838 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19840 2011-05-19 Glenn Morris <rgm@gnu.org>
19842 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19843 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19844 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19845 (lisp): Set the order to that of loadup.el.
19846 (shortlisp): Make it a copy of $lisp.
19847 (SOME_MACHINE_LISP): Remove.
19848 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19849 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19851 2011-05-18 Kenichi Handa <handa@m17n.org>
19853 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19854 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19855 (find_automatic_composition): Mostly rewrite for efficiency.
19857 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19859 * makefile.w32-in: Update dependencies.
19861 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19863 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19864 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19866 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19868 Fix some integer overflow issues, such as string length overflow.
19870 * insdel.c (count_size_as_multibyte): Check for string overflow.
19872 * character.c (lisp_string_width): Check for string overflow.
19873 Use EMACS_INT, not int, for string indexes and lengths; in
19874 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19875 the resulting string length overflows an EMACS_INT; instead,
19876 report a string overflow if no precision given. When checking for
19877 precision exhaustion, use a check that cannot possibly have
19878 integer overflow. (Bug#8675)
19879 * character.h (lisp_string_width): Adjust to new signature.
19881 * alloc.c (string_overflow): New function.
19882 (Fmake_string): Use it. This doesn't change behavior, but saves
19883 a few bytes and will simplify future changes.
19884 * character.c (string_escape_byte8): Likewise.
19885 * lisp.h (string_overflow): New decl.
19887 Fixups, following up to the user-interface timestamp change.
19888 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19889 for UI timestamps, instead of unsigned long.
19890 * msdos.c (mouse_get_pos): Likewise.
19891 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19892 * w32gui.h (Time): Define by including "systime.h" rather than by
19893 declaring it ourselves. (Bug#8664)
19895 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19896 * image.c (clear_image_cache): Likewise.
19898 * term.c (term_mouse_position): Don't assume time_t wraparound.
19900 Be more systematic about user-interface timestamps.
19901 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19902 and sometimes 'EMACS_UINT', to represent these timestamps.
19903 This change causes it to use 'Time' uniformly, as that's what X uses.
19904 This makes the code easier to follow, and makes it easier to catch
19905 integer overflow bugs such as Bug#8664.
19906 * frame.c (Fmouse_position, Fmouse_pixel_position):
19907 Use Time, not unsigned long, for user-interface timestamps.
19908 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19909 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19910 * keyboard.h (last_event_timestamp): Likewise.
19911 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19912 * menu.h (xmenu_show): Likewise.
19913 * term.c (term_mouse_position): Likewise.
19914 * termhooks.h (struct input_event.timestamp): Likewise.
19915 (struct terminal.mouse_position_hook): Likewise.
19916 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19917 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19918 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19919 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19920 what it was before.
19921 * menu.h, termhooks.h: Include "systime.h", for Time.
19923 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19924 Don't assume that the difference between two unsigned long values
19925 can fit into an integer. At this point, we know button_down_time
19926 <= event->timestamp, so the difference must be nonnegative, so
19927 there's no need to cast the result if double-click-time is
19928 nonnegative, as it should be; check that it's nonnegative, just in
19929 case. This bug is triggered when events are more than 2**31 ms
19930 apart (about 25 days). (Bug#8664)
19932 * xselect.c (last_event_timestamp): Remove duplicate decl.
19933 (x_own_selection): Remove needless cast to unsigned long.
19935 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19936 that always fit in int. Use a sentinel instead of a counter, to
19937 avoid a temp and to allay GCC's concerns about possible int overflow.
19938 * frame.h (struct frame): Use int for menu_bar_items_used
19939 instead of EMACS_INT, since it always fits in int.
19941 * menu.c (grow_menu_items): Check for int overflow.
19943 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19945 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19946 Before, the code was not consistent. These values cannot exceed
19947 2**31 - 1 so there's no need to make them unsigned.
19948 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19949 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19950 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19952 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19954 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19955 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19956 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19957 presumably because the widths might not match.
19959 * window.c (size_window): Avoid needless test at loop start.
19961 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19963 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19965 2011-05-12 Drew Adams <drew.adams@oracle.com>
19967 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19969 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19971 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19972 `width' to `bar_area_x' and `bar_area_width', respectively.
19973 (x_scroll_run): Take account of fringe background extension.
19975 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19976 Rename local vars `left' and `width' to `bar_area_x' and
19977 `bar_area_width', respectively.
19978 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19979 background extension.
19981 2011-05-10 Jim Meyering <meyering@redhat.com>
19983 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19985 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19987 * image.c (Finit_image_library): Return t for built-in image types,
19988 like pbm and xbm. (Bug#8640)
19990 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19992 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19994 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19996 * w32console.c (Fset_screen_color): Doc fix.
19997 (Fget_screen_color): New function.
19998 (syms_of_ntterm): Defsubr it.
20000 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20001 unlink the temporary file if Fcall_process didn't create it in the
20003 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20004 child process will be redirected to a file specified with `:file'.
20005 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20006 cue to call_process_cleanup not to close that handle.
20008 2011-05-07 Ben Key <bkey76@gmail.com>
20010 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20011 one of two shell specific rules, either bootstrap-temacs-CMD or
20012 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20013 to the previous implementation of the bootstrap-temacs rule.
20014 The bootstrap-temacs-CMD rule is similar to the previous
20015 implementation of the bootstrap-temacs rule except that it
20016 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20019 These changes, along with some changes to nt/configure.bat,
20020 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20021 earlier fix to add support for --cflags and --ldflags options
20022 that include quotes so that it works whether make uses cmd or
20025 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20027 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20028 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20030 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20031 a string. Handle both cases.
20032 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20033 (Fdbus_register_method): Use Qinvalid_function.
20035 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20037 * makefile.w32-in: Update dependencies.
20038 (LISP_H): Add inttypes.h and stdin.h.
20039 (PROCESS_H): Add unistd.h.
20041 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20043 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20044 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20046 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20048 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20050 * term.c (vfatal): Remove stray call to va_end.
20051 It's not needed and the C Standard doesn't allow it here anyway.
20053 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20054 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20056 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20059 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20061 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20063 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20065 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20067 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20069 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20070 * charset.c (Fdefine_charset_internal): Don't initialize
20071 charset.code_space[15]. The value was garbage, on hosts with
20072 32-bit int (Bug#8600).
20074 * lread.c (read_integer): Be more consistent with string-to-number.
20075 Use string_to_number to do the actual conversion; this avoids
20076 rounding errors and fixes some other screwups. Without this fix,
20077 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20078 (digit_to_number): Move earlier, for benefit of read_integer.
20079 Return -1 if the digit is out of range for the base, -2 if it is
20080 not a digit in any supported base. (Bug#8602)
20082 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20084 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20085 to match comment at start of function. This also removes a
20086 GCC warning about overflow in a 32+64-bit port.
20088 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20090 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20091 Reported by Stefan Monnier in
20092 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20093 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20094 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20096 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20097 (EMACS_UINTPTR): Likewise, with uintptr_t.
20099 * lisp.h: Prefer 64-bit EMACS_INT if available.
20100 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20101 on 32-bit hosts that have 64-bit int, so that they can access
20103 However, temporarily disable this change unless the temporary
20104 symbol WIDE_EMACS_INT is defined.
20106 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20108 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20109 This removes an assumption that EMACS_INT and long are the same
20110 width as pointers. The assumption is true for Emacs porting targets
20111 now, but we want to make other targets possible.
20112 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20113 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20114 In the rest of the code, change types of integers that hold casted
20115 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20116 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20117 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20118 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20119 No need to cast type when ORing.
20120 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20121 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20122 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20123 assume EMACS_INT is the same width as char *.
20124 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20125 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20126 Remove no-longer-needed casts.
20127 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20128 (xg_tool_bar_help_callback, xg_make_tool_item):
20129 Use EMACS_INTPTR to hold an integer
20130 that will be cast to void *; this can avoid a GCC warning
20131 if EMACS_INT is not the same width as void *.
20132 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20133 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20134 (current_message_1, set_message_1):
20135 Use a local to convert to proper width without a cast.
20136 * xmenu.c (dialog_selection_callback): Likewise.
20138 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20139 Also, don't assume VALBITS / RAND_BITS is less than 5,
20140 and don't rely on undefined behavior when shifting a 1 left into
20142 * lisp.h (get_random): Change signature to match.
20144 * lread.c (hash_string): Use size_t, not int, for hash computation.
20145 Normally we prefer signed values; but hashing is special, because
20146 it's better to use unsigned division on hash table sizes so that
20147 the remainder is nonnegative. Also, size_t is the natural width
20148 for hashing into memory. The previous code used 'int', which doesn't
20149 retain enough info to hash well into very large tables.
20150 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20152 * dbusbind.c: Don't possibly lose pointer info when converting.
20153 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20154 Use XPNTR rather than XHASH, so that the high-order bits of
20155 the pointer aren't lost when converting through void *.
20157 * eval.c (Fautoload): Don't double-shift a pointer.
20159 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20161 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20163 * gnutls.c (DEF_GNUTLS_FN):
20164 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20166 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20168 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20171 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20173 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20174 New version that can reserve upto 2GB of heap space.
20176 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20178 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20180 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20182 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20183 `gnutls_certificate_set_x509_key_file'.
20185 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20187 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20188 Update dependencies.
20190 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20192 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20193 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20194 Remove unused parameter `fildes'.
20195 * process.c (read_process_output, send_process): Don't pass it.
20197 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20199 Fix previous change: the library cache is defined in w32.c.
20200 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20201 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20203 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20205 Implement dynamic loading of GnuTLS on Windows.
20207 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20208 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20209 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20212 * gnutls.c (Qgnutls_dll): Define.
20213 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20214 (gnutls_*): Declare function pointers.
20215 (init_gnutls_functions): New function to initialize function pointers.

20218 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20219 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20220 (emacs_gnutls_write, emacs_gnutls_read)
20221 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20222 (Fgnutls_available_p): New function.
20223 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20224 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20225 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20227 * image.c: Include w32.h.
20228 (Vimage_type_cache): Delete.
20229 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20230 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20231 (w32_delayed_load): Move to w32.c.
20233 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20235 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20236 (w32_delayed_load): Move from image.c. When loading a library, record
20237 its filename in the :loaded-from property of the library id.
20238 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20239 Initialize and staticpro them.
20240 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20242 * process.c: Include lisp.h before w32.h, not after.
20243 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20244 instead of gnutls_record_check_pending.
20246 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20248 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20250 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20251 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20254 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20256 * xterm.c (x_set_frame_alpha): Do not set property on anything
20257 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20259 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20261 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20263 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20265 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

20273 (Qgnutls_bootprop_callbacks_verify): Make static.
20275 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
20277 * callproc.c: Indentation fixup.
20279 * sysdep.c (wait_for_termination_1): Make static.
20280 (wait_for_termination, interruptible_wait_for_termination):
20281 Move after wait_for_termination_1.
20283 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20285 * sysdep.c (interruptible_wait_for_termination): New function
20286 which is like wait_for_termination, but allows keyboard
20289 * callproc.c (Fcall_process): Add (:file "file") as an option for
20291 (Fcall_process_region): Ditto.
20293 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20295 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20296 rather than `XVECTOR (FOO)->size'.
20298 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20299 inttypes.h, as a gnulib replacement is used if it not available in
20302 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20304 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20305 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20306 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20308 * coding.c (coding_alloc_by_realloc): Error out if destination
20309 will grow beyond MOST_POSITIVE_FIXNUM.
20310 (decode_coding_emacs_mule): Abort if there isn't enough place in
20311 charbuf for the composition carryover bytes. Reserve an extra

20319 aborting when %lld or %lll format is passed.
20320 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20321 %llo or %llx format is passed. (Bug#8545)
20323 * window.c (window_scroll_line_based): Use a marker instead of
20324 simple variables to record original value of point. (Bug#7952)
20326 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20327 produced by %s or %c overflows available buffer space. (Bug#8545)
20329 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20331 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20332 (SIZE_MAX): Move defn after all includes, as they might #define it.
20334 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20336 * w32.c (init_environment): Warn about defaulting HOME to C:\.

20344 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20346 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20348 * doprnt.c (doprnt): Don't return value smaller than the buffer
20349 size if the message was truncated. (Bug#8545).
20351 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20353 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

20356 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20358 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20360 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20362 * makefile.w32-in: Update dependencies.
20364 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20366 Improve `doprnt' and its usage. (Bug#8545)
20367 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20368 `format_end'. Remove support for %l as a conversion specifier.
20369 Don't use xrealloc. Improve diagnostics when the %l size modifier
20370 is used. Update the commentary.
20372 * eval.c (verror): Simplify calculation of size_t.
20374 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20377 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20379 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20382 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20384 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20385 This makes this file independent of the recent pseudovector change.
20387 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20389 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20391 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20392 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20393 Remove unused local.
20394 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20396 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20397 GCC 4.6.0 optimizes based on type-based alias analysis.
20398 For example, if b is of type struct buffer * and v of type struct
20399 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20400 != &v->size, and therefore "v->size = 1; b->size = 2; return
20401 v->size;" must therefore return 1. This assumption is incorrect
20402 for Emacs, since it type-puns struct Lisp_Vector * with many other
20403 types. To fix this problem, this patch adds a new type struct
20404 vectorlike_header that documents the constraints on layout of vectors
20405 and pseudovectors, and helps optimizing compilers not get fooled
20406 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20407 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20408 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20410 (XSETPVECTYPE): Rewrite in terms of new macro.
20411 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20412 This is a bit clearer, and further avoids the possibility of
20413 undesirable aliasing.
20414 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20415 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20416 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20417 since Lisp_Subr is a special case (no "next" field).
20418 (ASIZE): Now uses header.size rather than size.
20419 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20420 to avoid the hassle of writing XVECTOR (foo)->header.size.
20421 (struct vectorlike_header): New type.
20422 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20423 object, to help avoid aliasing.
20424 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20425 (SUBRP): Likewise, since Lisp_Subr is a special case.
20426 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20427 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20428 (struct Lisp_Hash_Table): Combine first two members into a single
20429 struct vectorlike_header member. All uses of "size" and "next" members
20430 changed to be "header.size" and "header.next".
20431 * buffer.h (struct buffer): Likewise.
20432 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20433 * frame.h (struct frame): Likewise.
20434 * process.h (struct Lisp_Process): Likewise.
20435 * termhooks.h (struct terminal): Likewise.
20436 * window.c (struct save_window_data, struct saved_window): Likewise.
20437 * window.h (struct window): Likewise.
20438 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20439 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20440 * buffer.c (init_buffer_once): Likewise.
20441 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20443 * process.c (Fformat_network_address): Use local var for size,
20446 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20448 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20449 * data.c (atof): Remove decl; no longer used or needed.
20450 (digit_to_number): Move to lread.c.
20451 (Fstring_to_number): Use new string_to_number function, to be
20452 consistent with how the Lisp reader treats infinities and NaNs.
20453 Do not assume that floating-point numbers represent EMACS_INT
20454 without losing information; this is not true on most 64-bit hosts.
20455 Avoid double-rounding errors, by insisting on integers when
20456 parsing non-base-10 numbers, as the documentation specifies.
20457 * lisp.h (string_to_number): New decl, replacing ...
20458 (isfloat_string): Remove.
20459 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20460 (read1): Do not accept +. and -. as integers; this
20461 appears to have been a coding error. Similarly, do not accept
20462 strings like +-1e0 as floating point numbers. Do not report
20463 overflow for integer overflows unless the base is not 10 which
20464 means we have no simple and reliable way to continue.
20465 Break out the floating-point parsing into a new
20466 function string_to_number, so that Fstring_to_number parses
20467 floating point numbers consistently with the Lisp reader.
20468 (digit_to_number): Move here from data.c. Make it static inline.
20469 (E_CHAR, EXP_INT): Remove, replacing with ...
20470 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20471 (string_to_number): New function, replacing isfloat_string.
20472 This function checks for valid syntax and produces the resulting
20473 Lisp float number too. Rework it so that string-to-number
20474 no longer mishandles examples like "1.0e+". Use strtoumax,
20475 so that overflow for non-base-10 numbers is reported only when
20476 there's no portable and simple way to convert to floating point.
20478 * textprop.c (set_text_properties_1): Rewrite for clarity,
20479 and to avoid GCC warning about integer overflow.
20481 * intervals.h (struct interval): Use EMACS_INT for members
20482 where EMACS_UINT might cause problems. See
20483 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20484 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20485 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20487 (offset_intervals): Tell GCC not to worry about length overflow
20488 when negating a negative length.
20490 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20491 (overrun_check_free): Likewise.
20493 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20494 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20497 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20498 (gnutls_make_error): Rename local to avoid shadowing.
20499 (gnutls_emacs_global_deinit): ifdef out; not used.
20500 (Fgnutls_boot): Use const for pointer to readonly storage.
20501 Comment out unused local. Fix pointer signedness problems.
20503 * lread.c (openp): Don't stuff size_t into an 'int'.
20504 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20505 about possible signed overflow.
20507 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20508 (GDK_KEY_g): Don't define if already defined.
20509 (xg_prepare_tooltip): Avoid pointer signedness problem.
20510 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20512 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20513 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20515 * xfns.c (Fx_window_property): Simplify a bit,
20516 to make a bit faster and to avoid GCC 4.6.0 warning.
20517 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20519 * fns.c (internal_equal): Don't assume size_t fits in int.
20521 * alloc.c (compact_small_strings): Tighten assertion a little.
20523 Replace pEd with more-general pI, and fix some printf arg casts.
20524 * lisp.h (pI): New macro, generalizing old pEd macro to other
20525 conversion specifiers. For example, use "...%"pI"d..." rather
20526 than "...%"pEd"...".
20527 (pEd): Remove. All uses replaced with similar uses of pI.
20528 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20529 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20530 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20531 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20532 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20533 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20534 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20536 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20537 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20538 * print.c (safe_debug_print, print_object): Likewise.
20539 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20541 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20542 avoiding the 0 flag, which is not portable.
20543 * process.c (Fmake_network_process): Use pI to avoid cast.
20544 * region-cache.c (pp_cache): Likewise.
20545 * xdisp.c (decode_mode_spec): Likewise.
20546 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20547 behavior on 64-bit hosts with printf arg.
20548 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20549 (x_stop_queuing_selection_requests): Likewise.
20550 (x_get_window_property): Don't truncate byte count to an 'int'
20553 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20554 here, since it parses constructs like leading '-' and spaces,
20555 which are not wanted; and it overflows with large numbers.
20556 Instead, simply match F[0-9]+, which is what is wanted anyway.
20558 * alloc.c: Remove unportable assumptions about struct layout.
20559 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20560 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20561 (allocate_vectorlike, make_pure_vector): Use the new macros,
20562 plus offsetof, to remove unportable assumptions about struct layout.
20563 These assumptions hold on all porting targets that I know of, but
20564 they are not guaranteed, they're easy to remove, and removing them
20565 makes further changes easier.
20567 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20568 This doesn't fix a bug but makes the code clearer.
20569 (string_overrun_cookie): Now const. Use initializers that
20570 don't formally overflow signed char, to avoid warnings.
20571 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20572 can cause Emacs to crash when string overrun checking is enabled.
20573 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20574 multiple of sizeof (EMACS_INT); it need not be, if
20575 alignof(EMACS_INT) < sizeof (EMACS_INT).
20576 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20578 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20584 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20585 supposed to be handshaking. (Bug#8556)
20586 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20588 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

20598 * alloc.c (check_sblock, check_string_bytes)
20599 (check_string_free_list): Convert to standard C.
20601 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20603 * w32.c (emacs_gnutls_push): Fix typo.
20605 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20607 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20608 "cast to pointer from integer of different size".
20610 Improve doprnt and its use in verror. (Bug#8545)
20611 * doprnt.c (doprnt): Document the set of format control sequences
20612 supported by the function. Use SAFE_ALLOCA instead of always
20615 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20616 is one byte too soon. Don't use xrealloc; instead xfree and
20619 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20621 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20624 * gnutls.c: Renamed global_initialized to
20625 gnutls_global_initialized. Added internals for the
20626 :verify-hostname-error, :verify-error, and :verify-flags
20627 parameters of `gnutls-boot' and documented those parameters in the
20628 docstring. Start callback support.
20629 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20630 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20631 on error. Return error code.

20633 (emacs_gnutls_read): Likewise.
20634 (Fgnutls_boot): Return handshake error code.
20635 (emacs_gnutls_handle_error): New function.

20691 changes in globals.h immediately force recompilation.
20692 (TAGS): Depend on $(CURDIR)/m/intel386.h and
20693 $(CURDIR)/s/ms-w32.h.

20698 <char-direction-table>: Deleted.
20700 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20702 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
20703 * doprnt.c: Include limits.h.
20704 (SIZE_MAX): New macro.
20705 (doprnt): Return a size_t value. 2nd arg is now size_t.
20706 Many local variables are now size_t instead of int or unsigned.
20707 Improve overflow protection. Support `l' modifier for integer
20708 conversions. Support %l conversion. Don't assume an EMACS_INT
20709 argument for integer conversions and for %c.
20711 * lisp.h (doprnt): Restore prototype.
20713 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
20714 $(SRC)/character.h.
20716 * Makefile.in (base_obj): Add back doprnt.o.
20718 * deps.mk (doprnt.o): Add back prerequisites.
20719 (callint.o): Depend on character.h.
20721 * eval.c (internal_lisp_condition_case): Include the handler
20722 representation in the error message.
20723 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
20724 when breaking from the loop.

20728 * callint.c (Fcall_interactively): When displaying error message
20729 about invalid control letter, pass the character's codepoint, not
20730 a pointer to its multibyte form. Improve display of the character
20731 in octal and display also its hex code.
20733 * character.c (char_string): Use %x to display the (unsigned)
20734 codepoint of an invalid character, to avoid displaying a bogus
20737 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20738 `error', not SYMBOL_NAME itself.
20740 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20741 character arguments to `error'.
20743 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20744 to `error' in error message about FINAL_CHAR argument. Make sure
20745 FINAL_CHAR is a character, and use %c when it is passed as
20746 argument to `error'.

20810 Define only if needed.
20812 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
20813 by pacifying GCC about it. Maybe it's time to retire it?
20814 * xfaces.c (USG, __TIMEVAL__): Likewise.
20816 * dispextern.h (struct redisplay_interface): Rename param
20817 to avoid shadowing.
20818 * termhooks.h (struct terminal): Likewise.
20819 * xterm.c (xembed_send_message): Likewise.
20821 * insdel.c (make_gap_smaller): Define only if
20822 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
20824 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
20827 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
20828 so that we aren't warned about unused symbols.
20830 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
20832 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
20834 * xfns.c (x_real_positions): Mark locals as initialized.
20836 * xmenu.c (xmenu_show): Don't use uninitialized vars.
20838 * xterm.c: Fix problems found by static analysis with other toolkits.
20839 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
20840 (x_dispatch_event): Declare static if USE_GTK, and
20841 define if USE_GTK || USE_X_TOOLKIT.
20842 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
20843 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
20844 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
20845 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
20847 * xmenu.c (menu_help_callback): Pointer type fixes.
20848 Use const pointers when pointing at readonly data. Avoid pointer
20849 signedness clashes.

20851 (update_frame_menubar): Remove unused decl.
20853 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.

20935 * nsfont.m: Fixed bugs in ns_get_family and
20936 ns_descriptor_to_entity that were caused by using free to
20937 deallocate memory blocks that were allocated by xmalloc (via
20938 xstrdup). This caused Emacs to crash when compiled with
20939 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20940 --enable-checking=xmallocoverrun). xfree is now used to
20941 deallocate these memory blocks.

21303 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21304 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21305 was inaccessible from Lisp.
21306 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21307 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21309 alloc.c: Import and export fewer symbols, and remove unused items.
21310 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21312 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21313 it's not optimized away by whole-program optimization.
21314 (message_enable_multibyte, free_misc): Remove.
21315 (catchlist, handlerlist, mark_backtrace):
21316 Declare only if BYTE_MARK_STACK.
21317 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
21318 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
21319 (message_enable_multibyte): Remove decl.
21320 (free_misc, interval_free_list, float_block, float_block_index):
21321 (n_float_blocks, float_free_list, cons_block, cons_block_index):
21322 (cons_free_list, last_marked_index):
21324 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
21325 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21326 (mark_backtrace): Define only if BYTE_MARK_STACK.
21327 * xdisp.c (message_enable_multibyte): Now static.
21329 Declare Lisp_Object Q* variables to be 'static' if not exported.
21330 This makes it easier for human readers (and static analyzers)
21331 to see whether these variables are used from other modules.
21332 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21333 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21334 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
21335 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
21336 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
21337 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
21338 * xmenu.c, xselect.c:
21339 Declare Q* vars static if they are not used in other modules.
21340 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
21341 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
21342 Remove decls of unexported vars.
21343 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21345 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21347 Make Emacs functions such as Fatom 'static' by default.
21348 This makes it easier for human readers (and static analyzers)
21349 to see whether these functions can be called from other modules.
21350 DEFUN now defines a static function. To make the function external
21351 so that it can be used in other C modules, use the new macro DEFUE.
21352 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21353 (Finit_image_library):
21354 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21355 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21356 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21357 Remove decls, since these functions are now static.
21358 (Funintern, Fget_internal_run_time): New decls, since these functions
21359 were already external.
21361 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21362 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
21363 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
21364 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
21365 * keyboard.c, keymap.c, lread.c:
21366 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
21367 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
21368 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21369 Mark functions with DEFUE instead of DEFUN,
21370 if they are used in other modules.
21371 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21372 decls for now-static functions.
21373 * buffer.h (Fdelete_overlay): Remove decl.
21374 * callproc.c (Fgetenv_internal): Mark as internal.
21375 * composite.c (Fremove_list_of_text_properties): Remove decl.

21379 * doc.c (Fdocumntation_property): New forward static decl.
21380 * eval.c (Ffetch_bytecode): New forward static decl.
21381 (Funintern): Remove extern decl; now in .h file where it belongs.
21382 * fileio.c (Fmake_symbolic_link): New forward static decl.
21383 * image.c (Finit_image_library): New forward static decl.
21384 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21385 * intervals.h (Fprevious_property_change):
21386 (Fremove_list_of_text_properties): Remove decls.
21387 * keyboard.c (Fthis_command_keys): Remove decl.
21388 (Fcommand_execute): New forward static decl.
21389 * keymap.c (Flookup_key): New forward static decl.
21390 (Fcopy_keymap): Now static.
21391 * keymap.h (Flookup_key): Remove decl.
21392 * process.c (Fget_process): New forward static decl.
21393 (Fprocess_datagram_address): Mark as internal.
21394 * syntax.c (Fsyntax_table_p): New forward static decl.
21395 (skip_chars): Remove duplicate decl.

21397 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
21399 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
21400 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.

21404 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21406 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21409 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21411 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21412 when at ZV. (Bug#8487)
21414 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21416 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21418 * keyboard.c (parse_tool_bar_item): Likewise.
21419 * sound.c (sound_cleanup, alsa_close): Likewise.
21420 * termcap.c (tgetent): Likewise.
21421 * xfns.c (x_default_font_parameter): Likewise.
21422 * xsettings.c (read_and_apply_settings): Likewise.
21424 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21425 (overrun_check_free): Protoize.
21427 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21429 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21430 since callers should never pass a negative size.
21431 Change the signature to match that of plain 'read' and 'write'; see
21432 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21433 * lisp.h: Update prototypes of emacs_write and emacs_read.
21435 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21437 * xdisp.c (redisplay_window): Don't try to determine the character
21438 position of the scroll margin if the window start point w->startp
21439 is outside the buffer's accessible region. (Bug#8468)
21441 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21443 Fix write-region and its subroutines for buffers > 2GB.
21444 * fileio.c (a_write, e_write): Modify declaration of arguments and
21445 local variables to support buffers larger than 2GB.
21446 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21448 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21449 argument, local variables, and return value.
21451 * lisp.h: Update prototypes of emacs_write and emacs_read.
21453 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21455 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21457 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21459 Fix more problems found by GCC 4.6.0's static checks.
21461 * xdisp.c (vmessage): Use a better test for character truncation.
21463 * charset.c (load_charset_map): <, not <=, for optimization,
21464 and to avoid potential problems with integer overflow.
21465 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21466 * casetab.c (set_identity, shuffle): Likewise.
21467 * editfns.c (Fformat): Likewise.
21468 * syntax.c (skip_chars): Likewise.
21470 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21471 This also lets GCC 4.6.0 generate slightly better loop code.
21473 * callint.c (Fcall_interactively): <, not <=, for optimization.
21474 (Fcall_interactively): Count the number of arguments produced,
21475 not the number of arguments given. This is simpler and lets GCC
21476 4.6.0 generate slightly better code.
21478 * ftfont.c: Distingish more carefully between FcChar8 and char.
21479 The previous code passed unsigned char * to a functions like
21480 strlen and xstrcasecmp that expect char *, which does not
21481 conform to the C standard.
21482 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21483 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21484 char * when the C standard requires it.
21486 * keyboard.c (read_char): Remove unused var.
21488 * eval.c: Port to Windows vsnprintf (Bug#8435).
21489 Include <limits.h>.
21490 (SIZE_MAX): Define if the headers do not.
21491 (verror): Do not give up if vsnprintf returns a negative count.
21492 Instead, grow the buffer. This ports to Windows vsnprintf, which
21493 does not conform to C99. Problem reported by Eli Zaretskii.
21494 Also, simplify the allocation scheme, by avoiding the need for
21495 calling realloc, and removing the ALLOCATED variable.
21497 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21499 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21500 But keep the doprint source code for now, as we might revamp it
21501 and use it again (Bug#8435).
21502 * lisp.h (doprnt): Remove.
21503 * Makefile.in (base_obj): Remove doprnt.o.
21504 * deps.mk (doprnt.o): Remove.
21506 error: Print 32- and 64-bit integers portably (Bug#8435).
21507 Without this change, on typical 64-bit hosts error ("...%d...", N)
21508 was used to print both 32- and 64-bit integers N, which relied on
21509 undefined behavior.
21510 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21511 * lisp.h (error, verror): Mark as printf-like functions.
21512 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21513 Report overflow in size calculations when allocating printf buffer.
21514 Do not truncate output string at its first null byte.
21515 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21516 Truncate the output at a character boundary, since vsnprintf does not
21518 * charset.c (check_iso_charset_parameter): Convert internal
21519 character to string before calling 'error', since %c now has the
21521 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21522 overflow when computing char to be passed to 'error'. Do not
21523 pass Lisp_Object to 'error'; pass the integer instead.
21524 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21525 formatted with plain %d.
21527 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21529 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21531 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21533 * xterm.c (x_catch_errors): Remove duplicate declaration.
21535 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21537 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21539 2011-04-10 Jim Meyering <meyering@redhat.com>
21541 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21542 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21543 return ssize_t not "int", and use size_t as the buffer length.
21544 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21545 * gnutls.h: Update declarations.
21546 * process.c (read_process_output): Use ssize_t, to match.
21547 (send_process): Likewise.
21549 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21551 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21553 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21555 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21556 Use unsigned char, to match FcChar8 type definition.
21558 * xterm.c (handle_one_xevent):
21559 * xmenu.c (create_and_show_popup_menu):
21560 * xselect.c (x_decline_selection_request)
21561 (x_reply_selection_request): Avoid type-punned deref of X events.
21563 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21565 Fix some uses of `int' instead of EMACS_INT.
21566 * search.c (string_match_1, fast_string_match)
21567 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21568 (scan_buffer, find_next_newline_no_quit)
21569 (find_before_next_newline, search_command, Freplace_match)
21570 (Fmatch_data): Make some `int' variables be EMACS_INT.
21572 * xdisp.c (display_count_lines): 3rd argument and return value now
21573 EMACS_INT. All callers changed.
21574 (pint2hrstr): Last argument is now EMACS_INT.
21576 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21577 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21578 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21579 (decode_coding_utf_16, decode_coding_emacs_mule)
21580 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21581 (decode_coding_ccl, decode_coding_charset)
21582 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21583 (decode_coding_iso_2022, decode_coding_emacs_mule)
21584 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21585 <char_offset, last_offset>: Declare EMACS_INT.
21586 (encode_coding_utf_8, encode_coding_utf_16)
21587 (encode_coding_emacs_mule, encode_invocation_designation)
21588 (encode_designation_at_bol, encode_coding_iso_2022)
21589 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21590 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21592 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21593 (encode_invocation_designation): Last argument P_NCHARS is now
21595 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21596 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21598 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21601 * ccl.c (Fccl_execute_on_string): Declare some variables
21604 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21606 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21608 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21610 * process.c (Fformat_network_address): Doc fix.
21612 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21614 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21616 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21618 * keyboard.c (read_char): Call Lisp function help-form-show,
21619 instead of using internal_with_output_to_temp_buffer.
21620 (Qhelp_form_show): New var.
21621 (syms_of_keyboard): Use DEFSYM macro.
21623 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21625 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21627 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21629 * process.c (Flist_processes): Remove to Lisp.
21630 (list_processes_1): Delete.
21632 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21634 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21636 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21638 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21640 Fix more problems found by GCC 4.6.0's static checks.
21642 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21644 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21646 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21648 * xdisp.c (vmessage): Mark as a printf-like function.
21650 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21652 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21654 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21655 printf-like functions.
21656 (tiff_load): Add casts to remove these marks before passing them
21657 to system-supplied API.
21659 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21661 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21662 This avoids several warnings with gcc -Wstrict-overflow.
21663 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21664 directly, rather than having caller test rule sign. This avoids
21665 some unnecessary tests.
21666 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21667 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21668 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21670 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21671 (xfont_open): Avoid unnecessary tests.
21673 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21675 * composite.h, composite.c (composition_gstring_put_cache):
21676 Use EMACS_INT, not int, for length.
21678 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21679 breaking out part of COMPOSITION_DECODE_RULE.
21680 (COMPOSITION_DECODE_RULE): Use it.
21681 * composite.c (get_composition_id): Remove unused local vars,
21682 by using the new macro.
21684 * textprop.c (set_text_properties_1): Change while to do-while,
21685 since the condition is always true at first.
21687 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21688 (interval_deletion_adjustment): Return unsigned value.
21691 * process.c (list_processes_1, create_pty, read_process_output):
21692 (exec_sentinel): Remove vars that were set but not used.
21693 (create_pty): Remove unnecessary "volatile"s.
21694 (Fnetwork_interface_info): Avoid possibility of int overflow.
21695 (read_process_output): Do adaptive read buffering even if carryover.
21696 (read_process_output): Simplify nbytes computation if buffered.
21698 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
21700 * syntax.c (scan_words): Remove var that was set but not used.
21701 (update_syntax_table): Use unsigned instead of int.
21703 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21704 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21705 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21707 * print.c (print_error_message): Avoid int overflow.
21709 * font.c (font_list_entities): Redo for clarity,
21710 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21712 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21713 (font_score): Avoid potential overflow in diff calculation.
21715 * fns.c (substring_both): Remove var that is set but not used.
21716 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21718 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21720 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21721 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21722 can always succeed if overflow has undefined behavior.
21724 * search.c (boyer_moore, wordify): Remove vars set but not used.
21725 (wordify): Omit three unnecessary tests.
21727 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21728 All callers changed. This avoids the need for an unused var.

21740 Check for integer overflow on size calculations.
21742 * buffer.c (Fprevious_overlay_change): Remove var that is set
21745 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21746 Remove vars that are set but not used.
21747 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21748 (timer_check_2): Mark vars as initialized.

21752 * image.c (lookup_image): Remove var that is set but not used.
21753 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21755 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21756 that are set but not used.
21758 * xfns.c (make_invisible_cursor): Don't return garbage
21759 if XCreateBitmapFromData fails (Bug#8410).
21761 * xselect.c (x_get_local_selection, x_handle_property_notify):
21762 Remove vars that are set but not used.
21764 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

21769 (scroll_bar_windows_size): Now size_t, not int.
21770 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21771 Check for overflow.
21773 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21774 (map_tty_color) [!defined MSDOS]: Likewise.
21776 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21778 * coding.c: Remove vars that are set but not used.
21779 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

21788 * print.c (print_object): Remove var that is set but not used.
21790 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21791 The gnulib version avoids calling malloc in the usual case,
21792 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21793 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21794 * filelock.c (current_lock_owner): Likewise.
21795 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21796 * sysdep.c: Include allocator.h, careadlinkat.h.
21797 (emacs_no_realloc_allocator): New static constant.
21798 (emacs_readlink): New function.
21799 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21800 ../lib/careadlinkat.h.

21826 do not dereference NULL upon failed strdup
21827 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21828 (ns_get_family): Likewise.
21830 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21832 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21834 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21836 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21839 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21841 Add lexical binding.
21843 * window.c (Ftemp_output_buffer_show): New fun.

21852 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21854 (syms_of_lread): Declare `lexical-binding'.
21856 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21858 * keyboard.c (eval_dyn): New fun.
21859 (menu_item_eval_property): Use it.
21861 * image.c (parse_image_spec): Use Ffunctionp.
21863 * fns.c (concat, mapcar1): Accept byte-code-functions.
21865 * eval.c (Fsetq): Handle lexical vars.
21866 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21867 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21868 (FletX, Flet): Obey lexical binding.
21869 (Fcommandp): Handle closures.
21870 (Feval): New `lexical' arg.
21871 (eval_sub): New function extracted from Feval. Use it almost
21872 everywhere where Feval was used. Look up vars in lexical env.
21874 (Ffunctionp): Move from subr.el.
21875 (Ffuncall): Handle closures.
21876 (apply_lambda): Remove `eval_flags'.
21877 (funcall_lambda): Handle closures and new byte-code-functions.
21878 (Fspecial_variable_p): New function.
21879 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21880 but without exporting it to Lisp.
21882 * doc.c (Fdocumentation, store_function_docstring):
21883 * data.c (Finteractive_form): Handle closures.
21885 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21888 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21890 (exec_byte_code): New function extracted from Fbyte_code to handle new
21891 calling convention for byte-code-functions. Add new byte-codes.
21893 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

21899 * xdisp.c (redisplay_internal): Fix prototype.
21901 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21903 * xdisp.c (SCROLL_LIMIT): New macro.
21904 (try_scrolling): Use it when setting scroll_limit.
21905 Limit scrolling to 100 screen lines.
21906 (redisplay_window): Even when falling back on "recentering",
21907 position point in the window according to scroll-conservatively,
21908 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21910 (try_scrolling): When point is above the window, allow searching
21911 as far as scroll_max, or one screenful, to compute vertical
21912 distance from PT to the scroll margin position. This prevents
21913 try_scrolling from unnecessarily failing when
21914 scroll-conservatively is set to a value slightly larger than the
21915 window height. Clean up the case of PT below the margin at bottom
21916 of window: scroll_max can no longer be INT_MAX. When aggressive
21917 scrolling is in use, don't let point enter the opposite scroll
21918 margin as result of the scroll.
21919 (syms_of_xdisp) <scroll-conservatively>: Document the
21920 threshold of 100 lines for never-recentering scrolling.

21927 (message_log_check_duplicate): Remove parameters `prev_bol' and
21928 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21929 (redisplay_internal): Remove parameter `preserve_echo_area',
21930 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21932 * indent.c (Fvertical_motion):
21933 * window.c (window_scroll_pixel_based, Frecenter):
21934 Don't pass `need_y_p' to `move_it_by_lines'.
21936 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21938 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21939 steal a few bits to be more compact.
21940 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21941 Remove unneeded casts.
21943 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21945 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21947 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21948 binding" message (bug#7967).
21950 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21952 Fix more problems found by GCC 4.6.0's static checks.
21954 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21955 Remove unused local var.
21957 * editfns.c (Fmessage_box): Remove unused local var.
21959 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21960 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21961 Omit unused local vars.
21962 * window.c (shrink_windows): Omit unused local var.
21963 * menu.c (digest_single_submenu): Omit unused local var.
21964 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21965 Omit unused local var.
21967 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21968 Don't assume string length fits in int.
21969 (keyremap_step, read_key_sequence): Use size_t for sizes.

21973 instead of alloca (Bug#8344).
21975 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21976 (Fbacktrace_frame): Don't assume nframes fits in int.
21978 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21985 * cm.c (calccost): Turn while-do into do-while, for clarity.
21987 * keyboard.c (syms_of_keyboard): Use the same style as later
21988 in this function when indexing through an array. This also
21989 works around GCC bug 48267.
21991 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21993 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21995 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21996 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21998 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21999 This avoids undefined behavior on integer overflow, and is a bit
22000 more convenient anyway since it is compared to a size_t variable.
22002 Variadic C functions now count arguments with size_t, not int.
22003 This avoids an unnecessary limitation on 64-bit machines, which
22004 caused (substring ...) to crash on large vectors (Bug#8344).

22014 * fns.c (concat): Likewise.
22015 * frame.c (x_set_frame_parameters): Likewise.
22016 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22017 0 if not found, not -1. All callers changed.
22019 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22020 (stack_copy_size): Now size_t, not int.
22021 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22023 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22025 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22026 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22046 Vcommand_hook_internal.

22185 Remove unused variable `width'.
22187 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22189 * w32term.c (x_set_glyph_string_clipping):
22190 Don't pass uninitialized region to CombineRgn.

22216 * term.c (Fsuspend_tty, Fresume_tty):
22217 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22218 * window.c (temp_output_buffer_show):

22226 * buffer.c (Fkill_all_local_variables):
22227 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22229 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22230 unconditionally since it does the check itself.
22232 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22234 Fix more problems found by GCC 4.5.2's static checks.
22236 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22237 the first time through the loop, since we know p0 < p1 then.
22238 This also avoids a gcc -Wstrict-overflow warning.
22240 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22241 leading to a memory leak, possible in functions like
22242 load_charset_map_from_file that can allocate an unbounded number
22243 of objects (Bug#8318).
22245 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22246 that could (at least in theory) be that large.
22248 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22249 This is less likely to overflow, and avoids undefined behavior if
22250 overflow does occur. All callers changed. Use strtoul to scan
22251 for the unsigned long integer.
22252 (pint2hrstr): Simplify and tune code slightly.
22253 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22255 * scroll.c (do_scrolling): Work around GCC bug 48228.
22256 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22258 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22259 This also avoids a warning with gcc -Wstrict-overflow.
22260 (validate_x_resource_name): Simplify count usage.
22261 This also avoids a warning with gcc -Wstrict-overflow.
22263 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22266 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22268 * process.c (Fmake_network_process): Use socklen_t, not int,
22269 where POSIX says socklen_t is required in portable programs.
22270 This fixes a porting bug on hosts like 64-bit HP-UX, where
22271 socklen_t is wider than int (Bug#8277).
22272 (Fmake_network_process, server_accept_connection):
22273 (wait_reading_process_output, read_process_output):
22276 * process.c: Rename or move locals to avoid shadowing.

22286 Make tparam.h and terminfo.c consistent.
22287 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22288 Include tparam.h instead, since it declares them.
22289 * cm.h (PC): Remove extern decl; tparam.h now does this.
22290 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22291 * terminfo.c: Include tparam.h, to check interfaces.
22292 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22293 (tparam): Adjust signature to match interface in tparam.h;
22294 this removes some undefined behavior. Check that outstring and len
22295 are zero, which they always are with Emacs.
22296 * tparam.h (PC, BC, UP): New extern decls.
22298 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22299 (xftfont_open): Rename locals to avoid shadowing.
22301 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22302 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22303 (OTF_TAG_SYM): Omit macro if not needed.

22311 * xml.c (make_dom): Now static.
22313 * composite.c (composition_compute_stop_pos): Rename local to
22315 (composition_reseat_it): Remove unused locals.
22316 (find_automatic_composition, composition_adjust_point): Likewise.
22317 (composition_update_it): Mark var as initialized.
22318 (find_automatic_composition): Mark vars as initialized,
22319 with a FIXME (Bug#8290).

22322 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22323 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22324 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22325 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22326 to avoid shadowing.
22328 * textprop.c (property_change_between_p): Remove; unused.
22330 * intervals.c (interval_start_pos): Now static.
22332 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22335 Rename locals to avoid shadowing.
22337 * sound.c (wav_play, au_play, Fplay_sound_internal):
22338 Fix pointer signedness.
22339 (alsa_choose_format): Remove unused local var.
22340 (wav_play): Initialize a variable to 0, to prevent undefined
22341 behavior (Bug#8278).
22343 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22345 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22347 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22348 clobbering (Bug#8298).
22349 * sysdep.c (sys_subshell): Likewise.
22350 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22352 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22353 This should get cleaned up, so that child_setup has the
22354 same signature on all platforms.
22356 * callproc.c (call_process_cleanup): Now static.
22357 (relocate_fd): Rename locals to avoid shadowing.
22359 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22361 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22362 not to be necessary, and produces flickering.
22364 2011-03-20 Glenn Morris <rgm@gnu.org>
22366 * config.in: Remove file.
22368 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22370 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22371 are now in src/globals.h.
22372 (syms_of_minibuf): Remove spurious & from previous change.
22374 2011-03-20 Leo Liu <sdl.web@gmail.com>
22376 * minibuf.c (completing-read-function): New variable.
22377 (completing-read-default): Rename from completing-read.
22378 (completing-read): Call completing-read-function.
22380 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22382 * xfaces.c (Fx_load_color_file):
22383 Read color file from absolute filename (bug#8250).
22385 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22387 * makefile.w32-in: Update dependencies.
22389 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22391 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22397 * process.c (make_serial_process_unwind, send_process_trap):
22398 (sigchld_handler): Now static.
22400 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22401 That way, the code declares only the vars that it needs.
22402 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22403 * s/cygwin.h (PTY_ITERATION): Likewise.
22404 * s/darwin.h (PTY_ITERATION): Likewise.

22410 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22411 (CONSTANTLIM): Remove; unused.
22412 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22413 Define only if needed.
22415 * unexelf.c (unexec): Name an expression,
22416 to avoid gcc -Wbad-function-cast warning.
22417 Use a different way to cause a compilation error if anyone uses
22418 n rather than nn, a way that does not involve shadowing.
22419 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22421 * deps.mk (unexalpha.o): Remove; unused.
22423 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22424 * unexec.h: New file.
22425 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22426 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22427 Depend on unexec.h.
22428 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22429 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22430 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22431 Change as necessary to match prototype in unexec.h.
22433 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
22435 (back_comment, skip_chars): Mark vars as initialized.

22450 (font_sort_entities): Mark var as initialized.
22452 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
22454 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

22479 (Fcall_interactively): Rename locals to avoid shadowing.
22480 Use const pointer when appropriate.

22486 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22487 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22488 some of which prompt warnings from gcc -Wbad-function-cast.
22489 (Fformat_time_string, Fencode_time, Finsert_char):
22490 (Ftranslate_region_internal, Fformat):
22491 Rename or remove local vars to avoid shadowing.
22492 (Ftranslate_region_internal): Mark var as initialized.
22494 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22497 * lisp.h (eassert): Check that the argument compiles, even if
22498 ENABLE_CHECKING is not defined.
22500 * data.c (Findirect_variable): Name an expression, to avoid
22501 gcc -Wbad-function-cast warning.

22510 Rename locals to avoid shadowing.
22511 (mark_stack): Move local variables into the #ifdef region where
22513 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22514 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22516 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22517 (GC_STRING_CHARS): Remove; not used.
22518 (Fmemory_limit): Cast sbrk's returned value to char *.
22520 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22521 avoids undefined behavior in theory.
22523 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.

22526 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22527 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22528 to use the following functions instead of these macros.
22529 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22530 EMACS_INT, since callers assume the returned value fits in int.
22531 (upcase1): Likewise, for UPCASE_TABLE.
22532 (uppercasep, lowercasep, upcase): New static inline functions.
22533 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22538 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
22539 (regex_compile, re_search_2, re_match_2_internal):
22540 Remove unused local vars.
22541 (FREE_VAR): Rewrite so as not to use empty "else",
22542 which gcc can warn about.
22543 (regex_compile, re_match_2_internal): Mark locals as initialized.
22544 (RETALLOC_IF): Define only if needed.
22545 (WORDCHAR_P): Likewise. This one is never needed, but is used
22546 only in a comment talking about a compiler bug, so put inside
22547 the #if 0 of that comment.
22548 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22549 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22552 * search.c (boyer_moore): Rename locals to avoid shadowing.
22553 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
22554 (PREV_CHAR_BOUNDARY): Likewise.
22556 * search.c (simple_search): Remove unused var.
22558 * dired.c (compile_pattern): Move decl from here ...

22564 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
22566 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
22567 Rename locals to avoid shadowing.
22568 (Fvertical_motion): Mark locals as initialized.
22570 * casefiddle.c (casify_object, casify_region): Now static.
22571 (casify_region): Mark local as initialized.
22573 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
22575 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22576 New macros, so that the caller can use some names other than
22577 gcpro1, gcpro2, etc.
22578 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22580 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22581 argument, for consistency with GCPRO2_VAR, etc: it is now the
22582 prefix of the variable, not the variable itself. All uses
22584 * dired.c (directory_files_internal, file_name_completion):
22585 Rename locals to avoid shadowing.
22587 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22588 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22589 dired.c's scmp function, had undefined behavior.
22590 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22591 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22592 * buffer.h: ... to here, because these macros use current_buffer,
22593 and the new implementation with inline functions needs to have
22594 current_buffer in scope now, rather than later when the macros
22596 (downcase, upcase1): New static inline functions.
22597 (DOWNCASE, UPCASE1): Reimplement using these functions.
22598 This avoids undefined behavior in expressions like
22599 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22600 from race conditions in accessing the global variables
22601 case_temp1 and case_temp2.
22602 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22603 * lisp.h (case_temp1, case_temp2): Remove their decls.
22604 * character.h (ASCII_CHAR_P): Move from here ...
22605 * lisp.h: ... to here, so that the inline functions mentioned
22606 above can use them.
22608 * dired.c (directory_files_internal_unwind): Now static.
22610 * fileio.c (file_name_as_directory, directory_file_name):
22611 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22613 (file_name_as_directory): Use const pointers when appropriate.
22614 (Fexpand_file_name): Likewise. In particular, newdir might
22615 point at constant storage, so make it a const pointer.
22616 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22617 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer

23049 Move these decls to tparam.h, and make them agree with what
23050 is actually in tparam.c. The previous trick of using incompatible
23051 decls in different modules does not conform to the C standard.
