9 * coding.h (enum coding_result_code): Remove
10 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
11 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
12 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
13 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)
14 (CODING_MODE_SAFE_ENCODING): Rearrange bit values.
15 (decode_coding_region, encode_coding_region, decode_coding_string):

19 (syms_of_coding): Likewise.
20 (ALLOC_CONVERSION_WORK_AREA): Use SAFE_ALLOCA.
21 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
22 (decode_coding_object): Simplify since xrealloc never returns NULL.
25 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
27 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
28 * sysdep.c (list_system_processes)
29 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
30 Make it a stub in this case; otherwise the build might fail,
31 and this code hasn't been tested on such hosts anyway.
32 Problem reported by Nelson H. F. Beebe in
33 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
34 and analyzed by Jérémie Courrèges-Anglas in

37 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
39 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
40 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
41 (get_visually_first_element, move_it_vertically_backward): Ajust users.
42 * bidi.c (bidi_find_paragraph_start): Likewise.
43 * indent.c (vmotion): Likewise.
45 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
47 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
48 * filelock.c: Include <c-ctype.h>.
49 (MAX_LFINFO): New top-level constant.
50 (lock_info_type): Remove members pid, boot_time. Add members at,
51 dot, colon. Change user member to be the entire buffer, not a
52 pointer. This allows us to handle the case where a foreign
53 pid or boot time exceeds the local range. All uses changed.
54 (LINKS_MIGHT_NOT_WORK): New constant.
55 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
56 (defined_WINDOWSNT): Remove.
57 (MAKE_LOCK_NAME, file_in_lock_file_name):
58 Always use .#FILE (not .#-FILE) for the file lock,
59 even if it is a regular file.
60 (rename_lock_file): New function.
61 (create_lock_file): Use it.
62 (create_lock_file, read_lock_data):
63 Prefer a symbolic link for the lock file, falling back on a
64 regular file if symlinks don't work. Do not try to create
65 symlinks on MS-Windows, due to security hassles. Stick with
66 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
67 link, rename, unlink, mkstemp) when creating locks, as a GNUish
68 host may be using a Windowsish file system, and cannot use
69 MS-Windows-only system calls. Fall back on mktemp if mkstemp
70 doesn't work. Don't fail merely because of a symlink-contents
71 length limit in the current file system; fall back on regular
72 files. Increase the symlink contents length limit to 8 KiB, this
73 should be big enough for any real use and doesn't crunch the
75 (create_lock_file, lock_file_1, read_lock_data):
76 Simplify allocation of lock file buffers now that they fit in 8 KiB.
77 (lock_file_1): Return error number, not bool. All callers changed.
78 (ELOOP): New macro, if not already defined.
79 (read_lock_data): Return size of lock file contents, not Lisp object.
80 All callers changed. Handle a race condition if some other process
81 replaces a regular-file lock with a symlink lock or vice versa,
82 while we're trying to read the lock.
83 (current_lock_owner): Parse contents more carefully, to help avoid
84 confusing a regular-file lock with some other application's use
85 of the file. Check for lock file contents being too long, or
86 not parsing correctly.
87 (current_lock_owner, lock_file):
88 Allow foreign pid and boot times that exceed the local range.
89 (current_lock_owner, lock_if_free, lock_file):
90 Simplify allocation of lock file contents.
91 * w32.c (sys_rename_replace): New function, containing most of
92 the contents of the old sys_rename.
94 (fchmod): New dummy function.
95 * w32.h (sys_rename_replace, fchmod): New decls.
97 2013-03-05 Eli Zaretskii <eliz@gnu.org>
99 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
100 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
101 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
102 <dmantipov@yandex.ru>.
104 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
106 * composite.c (get_composition_id, fill_gstring_header):
107 Use make_uninit_vector where appropriate.
108 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
109 * xselect.c (clean_local_selection_data): Likewise.
111 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
113 Fix misuse of ImageMagick that caused core dump (Bug#13846).
114 * image.c (imagemagick_load_image): Calculate height and width
115 after flattening the image, not before.
117 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
119 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
120 * ftfont.c (ftfont_shape_by_flt): Likewise.
121 * w32uniscribe.c (uniscribe_shape): Likewise.
123 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
125 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
126 The old approach, which fell back on DIR/.#FILE.0 through
127 DIR/.#FILE.9, had race conditions that could not be easily fixed.
128 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
129 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
130 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
131 because the locking mechanism was never reliable in that case).
132 This patch fixes this and other bugs discovered by a code
133 inspection that was prompted by
134 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
135 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
136 to avoid interoperability problems between the MS-Windows and
137 non-MS-Windows implementations. MS-Windows and non-MS-Windows
138 instances of Emacs now ignore each others' locks.
139 * filelock.c (defined_WINDOWSNT): New constant.
140 (MAKE_LOCK_NAME, fill_in_lock_file_name):
141 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
142 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
143 regular files on MS-Windows hosts.
144 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
145 Use SAFE_ALLOCA to avoid problems with long file names.
146 (MAX_LFINFO): Now a local constant, not a global macro.
147 (IS_LOCK_FILE): Remove.
148 (lock_file_1): Don't inspect errno if symlink call succeeds;
150 (lock_file): Document that this function can return if lock
152 (lock_file): Don't access freed storage.
154 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

158 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
160 * textprop.c: Use bool for booleans.
161 (validate_interval_range, Fadd_text_properties)
162 (Fremove_text_properties): Prefer bool to int when either works.
164 2013-03-02 Eli Zaretskii <eliz@gnu.org>
166 * textprop.c (Fadd_text_properties, Fremove_text_properties): If
167 the interval tree changes as a side effect of calling
168 modify_region, re-do processing starting from the call to
169 validate_interval_range. (Bug#13743)
171 2013-02-28 Eli Zaretskii <eliz@gnu.org>
173 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
176 2013-02-27 Eli Zaretskii <eliz@gnu.org>
178 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
179 _SH_DENYRW flag, instead of emacs_open, to deny any other process
180 access to the lock file until it is written and closed.
183 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
185 * callint.c (Qcall_interactively):
186 * macros.c (Qexecute_kbd_macro):
189 2013-02-26 Bastien Guerry <bzg@gnu.org>
191 * window.c (Frecenter): Tiny docstring enhancement.
193 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
195 Minor textprop integer cleanup.
196 * intervals.h, textprop.c (add_text_properties_from_list):
197 Return void, not int, since nobody uses the return value.
198 * textprop.c (validate_plist, add_properties, remove_properties)
199 (Fadd_text_properties):
200 Don't assume list length fits in int.
201 (interval_has_all_properties, interval_has_some_properties)
202 (interval_has_some_properties_list, add_properties, remove_properties)
203 (Fadd_text_properties, Fremove_text_properties)
204 (Fremove_list_of_text_properties, text_property_stickiness):
205 Use bool for booleans.
206 (Fadd_text_properties, Fremove_text_properties):
207 (Fremove_list_of_text_properties):
208 Reindent do-while as per GNU style.
210 2013-02-25 Eli Zaretskii <eliz@gnu.org>
212 Implement CLASH_DETECTION for MS-Windows.
214 * filelock.c [WINDOWSNT]: Include w32.h.
215 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
216 function of that name. Up-case the macro arguments.
217 (IS_LOCK_FILE): New macro.
218 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
219 (create_lock_file): New function, with body extracted from
221 [WINDOWSNT]: Implement lock files by writing a regular file with
222 the lock information as its contents.
223 (read_lock_data): New function, on Posix platforms just calls
225 [WINDOWSNT]: Read the lock info from the file.
226 (current_lock_owner): Call read_lock_data instead of calling
227 emacs_readlinkat directly.
228 (lock_file) [WINDOWSNT]: Run the file name through
231 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
232 just check if the process by that PID exists.
234 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
235 also present, as doing so will fail to error out if the file
238 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
240 * textprop.c (Fadd_text_properties, Fremove_text_properties)
241 (Fremove_list_of_text_properties): Skip all of the intervals in
242 the region between START and END that already have resp. don't
243 have the requested properties, not just the first one. Add
244 assertions that the loop afterwards always modifies the
245 properties. (Bug#13743)
247 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

279 (data_space_start): Now char *, to avoid casts.
280 (exceeds_lisp_ptr): New function, replacing the old

478 With this, it should be as good as it was in 23.3, though it's
479 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
480 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
481 * unexaix.c (start_of_text): Remove.
482 (_data, _text): Declare as char[], not int, as AIX manual suggests.
483 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
484 (orig_load_scnptr, orig_data_scnptr):
485 Now off_t, not long, since they are file offsets.
486 (make_hdr): Use _data, not start_of_data ().
487 This is the key part of the fix.
488 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
489 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
491 * pre-crt0.c (data_start): Initialize to 1.
492 This ports to compilers that optimize the external declaration
493 'int x = 0;' as if it were 'int x;' to shrink the executable.
495 Improve AIX port (Bug#13650).
496 This doesn't fix the bug, but it makes progress: Emacs builds now.
497 * unexaix.c: Include inttypes.h, stdarg.h.
498 (report_error, report_error_1): Mark as _Noreturn.
499 (report_error): Don't report the wrong errno.
500 (report_error_1): Now varargs. All callers changed.
501 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
502 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
503 (write_ptr): Use %p to print address rather than %lx and a cast
504 to unsigned long. Grow buffer a bit, to be safer.
506 2013-02-13 Eli Zaretskii <eliz@gnu.org>
508 * bidi.c (bidi_resolve_neutral): After finding the next
509 non-neutral character, accept NEUTRAL_ON type as well, because
510 directional control characters, such as LRE and RLE, have their
511 type converted to that by bidi_resolve_weak. This avoids aborts
512 when LRE/RLE follows a run of neutrals.
513 (bidi_move_to_visually_next): Assert that return value of
514 bidi_peek_at_next_level is non-negative. Negative values will
517 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
519 Minor getenv-related fixes.
520 * callproc.c (Fcall_process_region) [!DOS_NT]:
521 Avoid unnecessary duplicate call to getenv.
522 * callproc.c (init_callproc):
523 * dispnew.c (init_display):
524 * sysdep.c (sys_subshell):
525 Omit unnecessary cast of getenv or egetenv.
527 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
529 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
532 2013-02-12 Eli Zaretskii <eliz@gnu.org>
534 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
536 (display_line): Set w->region_showing to the value of
537 it->region_beg_charpos, not to -1. This fixes redisplay
538 optimization when cursor is moved up after M->. (Bug#13623)
540 (try_scrolling): Scroll text up more if point is too close to ZV
541 and inside the scroll margin. This makes sure point is moved
542 outside the scroll margin in these cases.
544 * window.h (struct window): region_showing can no longer be
547 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
549 Tune by using memchr and memrchr.
550 * doc.c (Fsnarf_documentation):
551 * fileio.c (Fsubstitute_in_file_name):
552 * search.c (find_newline, scan_newline):
553 * xdisp.c (pos_visible_p, display_count_lines):
554 Use memchr and memrchr rather than scanning byte-by-byte.
555 * search.c (find_newline): Rename from scan_buffer.
556 Omit first arg TARGET, as it's always '\n'. All callers changed.
558 Clean up read_key_sequence a tiny bit more.
559 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
560 (read_key_sequence): Remove unused locals.
562 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
564 Clean up read_key_sequence a bit; reread active keymaps after first event.
565 * keyboard.c (read_char, read_char_x_menu_prompt)
566 (read_char_minibuf_menu_prompt):
567 Replace nmaps+maps with a single `map' arg.
568 (follow_key): Operate on a single map.
569 (active_maps): New function.
570 (test_undefined): Also return true for nil bindings.
571 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
572 a single (composed) keymap. Remember `first_event' to choose the right
573 set of active keymaps. Recompute the set of keymaps after receiving
574 the first event. Remove GOBBLE_FIRST_EVENT.
575 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
576 * keyboard.h (read_char): Update declaration.
577 * lread.c (read_filtered_event): Adjust call to read_char.
579 2013-02-11 Eli Zaretskii <eliz@gnu.org>
581 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
582 Don't use the limitation on backwards movement when lines are truncated
583 in the window. (Bug#13675)
585 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
587 * marker.c (set_marker_internal): If desired position is passed
588 as a marker, avoid call to buf_charpos_to_bytepos.
589 * window.c (Fset_window_point): Omit redundant type checking.
590 (Fset_window_start): Likewise. Format comment.
591 (window_scroll_pixel_based): Use set_marker_restricted_both
592 with character and byte positions obtained from an iterator.
593 (Fset_window_configuration): Use set_marker_restricted_both.
594 * xdisp.c (message_dolog): Likewise.
596 2013-02-10 Eli Zaretskii <eliz@gnu.org>
598 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
599 When text lines are longer than window's screen lines, don't move back
600 too far. This speeds up some redisplay operations. (Bug#13675)
602 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
604 * syntax.c (scan_sexps_forward): Fix byte position calculation
605 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
607 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
609 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
612 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
614 Minor hashing refactoring.
615 * fns.c (SXHASH_REDUCE): Move to lisp.h.
616 (sxhash_float): Return EMACS_UINT, for consistency with the other
618 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
619 non-static inline function and therefore can't use static vars.
620 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
621 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
622 with the other hash functions.
624 2013-02-09 Eli Zaretskii <eliz@gnu.org>
626 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
627 XXXXXX part of the temporary file pattern is not downcased even
628 when w32-downcase-file-names is non-nil. (Bug#13661)
630 * xdisp.c (decode_mode_spec): Remove handling of %t.
632 * msdos.c (careadlinkatcwd): Remove.
634 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
636 * lread.c (skip_dyn_bytes): New function (bug#12598).
637 (read1): Use it. Use getc instead of READCHAR to read bytes.
638 (load_each_byte): Remove. Update users.
640 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
642 * search.c (scan_buffer): Calculate end byte position just once.
643 (scan_newline): Do not recalculate start_byte.
644 (search_command): Use eassert.
645 * syntax.c (struct lisp_parse_state): New member location_byte.
646 (scan_sexps_forward): Record from_byte and avoid redundant
647 character to byte position calculation ...
648 (Fparse_partial_sexp): ... here. Break too long line.
650 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
652 * lisp.h (make_uninit_vector): New function.
653 * alloc.c (Fvector, Fmake_byte_code):
654 * ccl.c (Fregister_ccl_program):
655 * charset.c (Fdefine_charset_internal, define_charset_internal):
656 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
657 * composite.c (syms_of_composite):
658 * font.c (Fquery_font, Ffont_info, syms_of_font):
659 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
660 * ftfont.c (ftfont_shape_by_flt):
661 * indent.c (recompute_width_table):
662 * nsselect.m (clean_local_selection_data):
663 * syntax.c (init_syntax_once):
664 * w32unsubscribe.c (uniscribe_shape):
665 * window.c (Fcurrent_window_configuration):
666 * xfaces.c (Fx_family_fonts):
667 * xselect.c (selection_data_to_lisp_data): Use it.
669 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
671 * coding.c (Fdefine_coding_system_internal): Use AREF where
672 argument is known to be a vector.
673 * fns.c (Flocale_info): Likewise for ASET.
674 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
675 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
677 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
679 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
682 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
683 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
684 updateCollectionBehaviour.
686 * nsterm.m (NEW_STYLE_FS): Remove.
687 (ns_last_use_native_fullscreen): New variable.
688 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
689 (x_set_window_size): Do not take title bar and tool bar into account
690 if isFullscreen returns YES.
691 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
692 (check_native_fs): New function.
693 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
694 (ns_term_init): Remove NEW_STYLE_FS.
695 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
696 and tool bar if isFullscreen returns NO.
697 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
698 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
700 (window:willUseFullScreenPresentationOptions:): New method.

702 Hide toolbar if not enabled (Bug#13444).
703 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
704 Restore tool bar if enabled, hide it otherwise (Bug#13444).
705 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
706 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
707 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
708 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
709 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
710 (syms_of_nsterm): Add ns-use-native-fullscreen.
712 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
714 * fileio.c (Qchoose_write_coding_system): Now static.
716 2013-02-04 Eli Zaretskii <eliz@gnu.org>
718 * xdisp.c (window_buffer_changed): region_showing can be negative,
719 which still means region is being displayed.
720 (redisplay_internal): Resurrect code that forced redisplay of the
721 whole window when showing region and the mark has changed.
722 Record the new mark position to allow redisplay optimizations.
723 (display_line): If it->region_beg_charpos is non-zero, set the
724 window's region_showing member to -1. (Bug#13623) (Bug#13626)
726 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
727 not bitfield of 1 bit.
729 2013-02-03 Daniel Colascione <dancol@dancol.org>
731 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
732 daemon mode works on cygw32 when Emacs is installed and not just
735 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
737 Avoid file time stamp bug on MS-Windows (Bug#13149).
738 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
739 as FAT32 doesn't update time stamps when truncating them.
740 Also, check that a file time stamp is not a multiple of 100 ns;
741 this should catch all instances of the problem on MS-Windows,
742 as its native file system resolution is 100 ns or worse, and
743 checking for a non-multiple of 100 ns should impose only a small
744 overhead on systems with ns resolution.
746 2013-02-02 Eli Zaretskii <eliz@gnu.org>
748 Avoid encoding file names on MS-Windows when they need to be run
749 through dostounix_filename.
750 * w32.c (normalize_filename): Accept an additional argument
751 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
752 downcase it even if w32-downcase-file-names is non-nil.
753 (dostounix_filename): Accept an additional argument MULTIBYTE and
754 pass it to normalize_filename.
755 (emacs_root_dir): Adjust.
757 * msdos.h (dostounix_filename): Adjust prototype.
759 * w32.h (dostounix_filename): Adjust prototype.
761 * msdos.c (dostounix_filename): Accept an additional argument and
763 (init_environment): Adjust callers of dostounix_filename.
765 * fileio.c (Ffile_name_directory, file_name_as_directory)
766 (directory_file_name, Fexpand_file_name)
767 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
769 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
771 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
772 variables, as egetenv is case-insensitive for DOS_NT.
774 * dired.c (file_name_completion): Don't call Fdirectory_file_name
775 with an encoded file name.
777 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
778 Adjust calls to dostounix_filename.
780 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
782 * unexw32.c (unexec): Adjust call to dostounix_filename.
784 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
786 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
789 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
792 * callproc.c (Fcall_process): Make sure program name in PATH and
793 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
794 is passed to exec/spawnve, which fails unless the file-name
797 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
798 even if w32-quote-process-args is nil.
800 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
802 Fix timestamp bug when write-region appends nothing (Bug#13149).
803 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
804 the file's time stamp doesn't change if Emacs happens to write nothing
805 to the file, and on a buggy file system this could cause Emacs to
806 incorrectly infer that the file system doesn't have the bug.
807 Avoid this problem by inhibiting the inference in this case.
809 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
811 * window.h (struct window): Convert base_line_number, base_line_pos
812 and column_number_displayed members from Lisp_Object to ptrdiff_t.
813 Convert region_showing member from Lisp_Object to bitfield.
814 Remove sequence_number member. Adjust comments.
815 * window.c (sequence_number): Remove.
816 (make_window): Initialize column_number_displayed.
817 * print.c (print_object): Follow the printed representation of
818 frames and print window pointer to distinguish between windows.
819 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
820 * xdisp.c (wset_base_line_number, wset_base_line_pos)
821 (wset_column_number_displayed, wset_region_showing): Remove.
822 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
823 (try_scrolling, try_cursor_movement, redisplay_window)
824 (try_window_reusing_current_matrix, try_window_id, display_line)
825 (display_mode_lines, decode_mode_spec): Adjust users.
826 * .gdbinit (pwinx): Do not print sequence_number.
828 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
830 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
831 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
832 * dired.c: Include <fcntl.h>.
833 (open_directory): New function, which uses open and fdopendir
834 rather than opendir. DOS_NT platforms still use opendir, though.
835 (directory_files_internal, file_name_completion): Use it.
836 (file_attributes): New function, with most of the old Ffile_attributes.
837 (directory_files_internal, Ffile_attributes): Use it.
838 (file_attributes, file_name_completion_stat): First arg is now fd,
839 not dir name. All uses changed. Use fstatat rather than lstat +
841 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
842 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
843 (emacs_readlinkat): New function, with much of the old
844 Ffile_symlink_p, but with an fd argument for speed.
845 It uses readlinkat rather than careadlinkatcwd, so that it
846 need not assume the working directory.
847 (Ffile_symlink_p): Use it.
848 * filelock.c (current_lock_owner): Use emacs_readlinkat
849 rather than emacs_readlink.
850 * lisp.h (emacs_readlinkat): New decl.
851 (READLINK_BUFSIZE, emacs_readlink): Remove.
852 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
853 (emacs_norealloc_allocator, emacs_readlink): Remove.
854 This stuff is moved to fileio.c.
855 * w32.c (fstatat, readlinkat): New functions.
856 (careadlinkat): Don't check that fd == AT_FDCWD.
857 (careadlinkatcwd): Remove; no longer needed.
859 2013-01-31 Glenn Morris <rgm@gnu.org>
861 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
862 (Fwrite_region): Update for new choose_write_coding_system args.
863 Move the last piece of choose_write_coding_system here. (Bug#13522)
864 (syms_of_fileio): Add choose-write-coding-system.
866 2013-01-30 Eli Zaretskii <eliz@gnu.org>
868 * w32.c (sys_open): Zero out the flags for the new file descriptor.
869 (sys_close): Zero out the flags for the file descriptor before
870 closing it. (Bug#13546)
872 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
873 (logon_network_drive, stat_worker, symlink, chase_symlinks):
874 Use CharNextExA and CharPrevExA to iterate over file names encoded in
877 * w32.c (w32_get_long_filename, init_environment, readlink):
878 Support file names encoded in DBCS codepages.
879 (readlink): Use the current file-name-coding-system, not the ANSI
880 codepage, to decode and handle targets of symlinks.
882 2013-01-28 Eli Zaretskii <eliz@gnu.org>
884 * w32.c (opendir): Now accepts a 'const char *'.
886 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
888 Remove obsolete redisplay code. See the discussion at
889 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
890 * dispnew.c (preemption_period, preemption_next_check): Remove.
891 (Vredisplay_preemption_period): Likewise.
892 (update_frame, update_single_window, update_window, update_frame_1):
893 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
894 used, following the 2012-06-22 change.
896 2013-01-25 Eli Zaretskii <eliz@gnu.org>
898 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
900 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
902 * font.c (num_fonts): Remove the leftover from old
903 debugging code. Adjust comment style here and there.
904 * insdel.c (insert_1): Remove.
905 * lisp.h (insert_1): Remove prototype.
906 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
908 2013-01-25 Eli Zaretskii <eliz@gnu.org>
910 * w32.c (max_filename_mbslen): New function.
911 (normalize_filename, readdir): Use it to detect locales where ANSI
912 encoding of file names uses a double-byte character set (DBCS).
913 If a DBCS encoding is used, advance by characters using
914 CharNextExA, instead of incrementing a 'char *' pointer.
915 Use _mbslwr instead of _strlwr. (Bug#13515)
917 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
918 request of memory reservation to 1.7GB. (Bug#13065)
920 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
922 * coding.c (detect_coding_iso_2022): Move back mis-reordered code

928 Avoid redundant calls to strlen.
930 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
932 Drop async_visible and async_iconified fields of struct frame.
933 This is possible because async input is gone; for details, see
934 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
935 * frame.h (struct frame): Remove async_visible and async_iconified
936 members, convert garbaged to unsigned bitfield. Adjust comments.
937 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
938 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
939 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
940 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
941 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
943 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
944 properly. Likewise for obscured.
946 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
949 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
951 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
953 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
954 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
956 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
958 * xdisp.c (message2, message2_nolog): Remove functions.
959 (message3, message3_nolog): Extract nbytes and multibyteness directly
960 from the string. Change all callers.
961 (message3_nolog): Don't set message_enable_multibyte since set_message
962 will reset it anyway.
963 (message1, message1_nolog): Use message3.
964 (vmessage): Use a stack allocated buffer rather than f->message_buf.
965 (with_echo_area_buffer): Remove last two arguments. Update all callers.
966 (set_message): Drop all but the second arg, which has to be a string.
967 (set_message_1): Simplify now that we know that a1 is NULL and the
968 second arg is a string.
969 * frame.h (struct frame): Remove `message_buf' field.
970 Use glyphs_initialized_p instead.
971 (FRAME_MESSAGE_BUF): Remove macro.
972 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
973 * lisp.h (message2, message2_nolog): Remove declarations.
974 (message3, message3_nolog): Update declarations.
975 * keyboard.c (read_char_minibuf_menu_text)
976 (read_char_minibuf_menu_width): Remove vars.
977 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
978 to correctly handle multibyte strings.
979 * frame.c (delete_frame): Don't free message_buf any more.
980 * editfns.c (message_text, message_length): Remove vars.
981 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
982 * fileio.c (auto_save_error): Use message3 instead of message2.
983 * dispnew.c (adjust_frame_message_buffer): Remove function.
985 2013-01-23 Eli Zaretskii <eliz@gnu.org>
987 * w32term.c (w32fullscreen_hook): Account correctly for the screen
988 real estate used for the tool bar and the menu bar.
990 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
992 * insdel.c (prepare_to_modify_buffer): Force redisplay if
993 hidden buffer is prepared to modification (Bug#13164).
995 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
997 * window.h (struct window): Change window_end_valid member from
998 Lisp_Object to a bitfield. Adjust comments.
999 (wset_window_end_valid): Remove.
1000 * window.c (adjust_window_count): Clear window_end_valid.
1001 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1002 (Fwindow_line_height, set_window_buffer, Frecenter)
1003 (Fsplit_window_internal, Fdelete_other_windows_internal)
1004 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1005 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1006 * xdisp.c (check_window_end, reconsider_clip_changes)
1007 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1008 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1009 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1011 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1013 * xdisp.c (mark_window_display_accurate): Simplify the loop
1014 assuming that the only one of vchild, hchild or buffer window
1015 slots is non-nil. Call mark_window_display_accurate_1 for
1016 the leaf windows only.
1017 (mark_window_display_accurate_1): Always assume leaf window.
1020 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1022 * emacs.c (Qkill_emacs_hook): Now static.
1024 * fileio.c (Finsert_file_contents): Simplify.
1025 Remove unnecessary assignments and tests.
1027 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1029 * w32.c (acl_set_file): Don't test for errors unless
1030 set_file_security returns FALSE. Avoids spurious errors when
1033 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1035 * fileio.c (Finsert_file_contents): Revert code introduced at
1036 2013-01-18 in favor of the simpler and generally better fix.
1037 Save stack space by removing 'buffer' and reusing 'read_buf'
1040 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1042 * lisp.h (eabs): Define unconditionally (Bug#13419).
1043 The old "#if !defined (eabs)" was an unnecessary revenant of back
1044 when this macro was called "abs". Document 'eabs' better.
1046 2013-01-19 Glenn Morris <rgm@gnu.org>
1048 * fns.c (Frandom): Doc fix.
1050 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1052 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1053 segfault when there are lots of overlays.
1055 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1056 when there are lots of overlays.
1057 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1058 for the details and a way to reproduce.
1060 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1062 * fileio.c: Use O_APPEND to append.
1063 This corresponds better to the natural interpretation of "append",
1064 and avoids the need to open the output file twice, or to invoke
1065 lseek when APPEND is neither nil nor a number.
1066 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1067 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1068 file possibly twice, and lseeking to its end; this avoids the
1069 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1070 at the same time: the combination is never needed and apparently
1071 it doesn't work with DOS_NT.
1073 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1074 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1076 Allow floating-point file offsets.
1077 Problem reported by Vitalie Spinu in
1078 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1079 * fileio.c (emacs_lseek): Remove.
1080 (file_offset): New function.
1081 (Finsert_file_contents, Fwrite_region): Use it.
1083 2013-01-19 Chong Yidong <cyd@gnu.org>
1085 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1086 aborting on Fsignal (Bug#13289).
1088 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1090 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1091 set_file_security as failure due to insufficient privileges.
1092 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1093 (fstat): Return owner and group like 'stat' and 'lstat' do.
1095 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1097 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1098 The bug was observed on Ubuntu operating inside a virtual machine,
1099 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1100 The workaround introduces a race condition on non-buggy hosts,
1101 but it's an unlikely race and anyway there's a nearly identical
1102 nearby race that can't be fixed.
1103 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1105 (Fwrite_region): Test for file system time stamp bug.
1106 (init_fileio): New function.
1107 * lisp.h (init_fileio): Declare it.
1108 * emacs.c (main): Call it.
1110 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1111 and make it more consistent with other stat-failure diagnostics.
1113 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1115 Fix crash when inserting data from non-regular files.
1116 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1117 for the error description produced by valgrind.
1118 * fileio.c (read_non_regular): Rename to read_contents.
1119 Free Lisp_Save_Value object used to pass parameters.
1120 (read_non_regular_quit): Rename to read_contents_quit.
1121 (Finsert_file_contents): Redesign internal file reading loop to adjust
1122 gap and end positions after each read and so help make_gap to work
1123 properly. Do not signal an I/O error too early and so do not leave
1124 not yet decoded characters in a buffer, which was the reason of
1125 redisplay crash. Use list2 to build return value. Adjust comments.
1127 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1129 Close a race when statting and reading files (Bug#13149).
1130 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1131 This avoids a race if the file is renamed between stat and open.
1132 This race is not the problem originally noted in Bug#13149;
1133 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1135 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1142 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1143 * alloc.c (format_save_value): Rename to make_save_value.
1144 (make_save_pointer): New function.
1145 (record_xmalloc): Use make_save_pointer.
1146 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1147 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1148 Change users of make_save_value to make_save_pointer.
1149 Likewise for format_save_value and make_save_value.

1160 * alloc.c (free_save_value): Now static.
1162 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1164 * keymap.c (map_keymap_internal): Use format_save_value.
1165 (map_keymap_char_table_item): Adjust accordingly.
1166 * fileio.c (non_regular_fd, non_regular_inserted)
1167 (non_regular_nbytes): Remove.
1168 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1169 Use format_save_value to pass parameters to read_non_regular.
1170 (read_non_regular): Use XSAVE_ macros to extract parameters.
1172 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1174 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1176 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1178 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1179 extraction from any Lisp_Save_Value slot. Add type checking.
1180 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1181 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1182 * xselect.c: All users changed.
1184 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1192 object with the specified internal structure.
1193 (make_save_value): Reimplement using format_save_value.
1194 * editfns.c (save_excursion_save): Use format_save_value.
1195 (save_excursion_restore): Use XSAVE_OBJECT.
1197 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1199 Avoid needless casts with XSAVE_POINTER.
1200 * alloc.c (mark_object) [GC_MARK_STACK]:
1201 * dired.c (directory_files_internal_unwind):
1202 * fileio.c (do_auto_save_unwind):
1203 * gtkutil.c (pop_down_dialog):
1204 * keymap.c (map_keymap_char_table_item):
1205 * lread.c (load_unwind):
1206 * nsmenu.m (pop_down_menu):
1207 * print.c (print_object) [GC_MARK_STACK]:
1208 * xfns.c (clean_up_file_dialog):
1209 * xmenu.c (cleanup_widget_value_tree):
1210 Omit casts between XSAVE_POINTER and a pointer type.
1212 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1214 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1215 * eval.c (eval_sub): Protect `form' from being GCed before its
1216 car and cdr becomes protected with the backtrace entry.
1218 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1220 Make Lisp_Save_Value more versatile storage for up to four objects.
1221 * lisp.h (toplevel): Enumeration to describe types of saved objects.
1222 (struct Lisp_Save_Value): New layout. Adjust comments.
1223 (XSAVE_POINTER): New macro.
1224 (XSAVE_INTEGER): Likewise.
1225 (allocate_misc): Add prototype.
1226 (free_misc): Likewise.
1227 * alloc.c (allocate_misc): Now global.
1228 (free_misc): Likewise. Adjust comment.
1229 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1230 (free_save_value): Likewise.
1231 (mark_object): Likewise.
1232 * editfns.c (save_excursion_save): Pack everything within
1233 Lisp_Save_Value and so avoid xmalloc.
1234 (save_excursion_restore): Adjust to match new layout. Use free_misc
1235 because we do not allocate extra memory any more. Add eassert.
1236 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1237 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1238 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
1239 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

1245 (nsfont_draw): Remove disabling of LCD smoothing.
1246 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
1247 Bug#11484 with LCD smoothing on.
1249 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1251 Fix SIGDANGER handlers, for AIX (Bug#13408).
1252 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1253 Move handlers here from emacs.c; they were out of place.
1255 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1257 * xterm.c (syms_of_xterm): Adjust documentation for
1258 scroll-bar-adjust-thumb-portion.
1260 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)

1273 (doCommandBySelector:): Set processingCompose to NO.
1275 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
1276 Remove check for fkeys count > zero, block/unblock fixes the real bug.
1277 (nsfont_list_family): Add block/unblock_input calls.
1278 (nsfont_open): Move block_input earlier. Add unblock_input before early
1280 (nsfont_draw): Add block/unblock_input calls.
1282 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
1284 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
1285 for old_charpos and old_bytepos.
1287 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
1289 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
1290 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
1291 Clear tzvalbuf_in_environ if this workaround is in effect.
1292 Problem and fix reported by Kazuhiro Ito.
1294 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
1296 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):

1303 string cross-reference(s).
1305 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1307 Avoid unnecessary byte position calculation for the gap movement.
1308 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1309 anyway, all of them should use move_gap_both instead.
1310 * lisp.h (move_gap): Remove prototype.
1311 * insdel.c (move_gap): Remove.
1312 (move_gap_both): Add eassert.
1313 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

1319 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1321 * term.c (init_tty): Use them instead of rolling our own code.
1322 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1323 switches from 'signal' to 'pthread_sigmask', which is safer in
1324 multithreaded applications.
1325 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1326 which has already arranged for that.
1327 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1328 This is the main part of the bug fix.
1330 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
1332 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around
1333 x_last_font_name (Bug#13403).
1335 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
1337 Omit buffer_slot_type_mismatch and use generic predicates to enforce
1338 the type of per-buffer values where appropriate.
1339 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
1340 predicate, which is how it's really used now. Adjust comment.
1341 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1342 * buffer.c (buffer_slot_type_mismatch): Remove.
1343 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

1347 left-margin-width, right-margin-width, left-fringe-width,
1348 right-fringe-width, scroll-bar-width and buffer-display-count.
1349 Use Qstringp for default-directory, buffer-file-name,
1350 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1351 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1353 * data.c (store_symval_forwarding): Adjust to call the predicate.
1355 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
1357 * w32.c (get_name_and_id, acl_set_file):
1358 * w32term.c (w32fullscreen_hook): Remove unused local variables.
1360 2013-01-09 Dmitry Antipov <dmantipov@yandex.ru>
1362 * lisp.h (make_gap_1): New prototype.
1363 * buffer.h (GAP_BYTES_DFL, GAP_BYTES_MIN): New macros for the special

1368 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
1369 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1370 (make_gap_1): New function to adjust the gap of any buffer.
1371 * coding.c (coding_alloc_by_making_gap): Use it.
1372 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1373 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1375 2013-01-08 Juri Linkov <juri@jurta.org>
1377 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
1378 of (supports :underline (:style wave)). (Bug#13000)
1380 2013-01-08 Aaron S. Hawley <aaron.s.hawley@gmail.com>
1382 * undo.c (Fprimitive_undo): Move to simple.el.

1387 * keyboard.c (echo_add_key): Rename from echo_add_char.
1389 2013-01-06 Chong Yidong <cyd@gnu.org>
1391 * keyboard.c (echo_add_char): New function, factored out from
1392 echo_char. Don't add a space if the previous echo string was
1394 (echo_char): Use it.
1395 (read_key_sequence): When echoing mock input, ensure that the
1396 trailing dash is properly added.
1398 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1400 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1401 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1402 digits for buffer positions, before misalignment starts.
1403 Display "0" for integer "object" field.
1404 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1405 Display the newline glyph more unambiguously.
1407 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1409 * nsterm.m (ns_draw_underwave):
1410 * w32term.c (w32_draw_underwave):
1411 * xterm.c (x_draw_underwave): Make underwave look more triangular
1412 and also degrade gracefully for small fonts. (Bug#13000)
1414 * nsterm.m (ns_draw_text_decoration):
1415 * w32term.c (x_draw_glyph_string):
1416 * xterm.c (x_draw_glyph_string): Don't use previous underline
1417 thickness and position if previous underline type is underwave.
1419 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1421 * fileio.c (Ffile_acl): Undocument return format.
1423 2013-01-02 Glenn Morris <rgm@gnu.org>
1425 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
1427 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>

1434 * fringe.c (compute_fringe_widths):
1435 * lread.c (read_list):
1436 * minibuf.c (Ftry_completion):
1437 * term.c (tty_ins_del_lines):
1438 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1439 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1441 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1443 * w32.c (unsetenv): Set up the string passed to _putenv
1445 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1446 for the bug this caused.
1448 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1450 * coding.c (Qmac): Now static.
1452 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1454 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1455 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
1456 handlebox_widget. Set toolbar_in_hbox to false/true, set
1457 toolbar_is_packed to true.
1458 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
1459 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1460 Show all on TOOLBAR_TOP_WIDGET.
1461 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1462 by TOOLBAR_TOP_WIDGET.
1463 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1464 Check toolbar_is_packed.
1465 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1466 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1467 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1469 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1470 (xg_update_menubar): Update title only if
1471 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1472 (xg_update_submenu): Skip tearoff only if
1473 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1474 (xg_initialize): Initialize xg_detached_menus only if
1475 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1477 * xterm.h (struct x_output): Surround handlebox_widget with
1478 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1479 toolbar_in_hbox is bool.
1481 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1483 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1484 (LIBS_GNUSTEP): Define.
1485 (LIBES): Add $(LIBS_GNUSTEP).
1486 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1488 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1490 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1491 continuation glyph on a TTY with an indication of an empty line.
1494 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1496 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1497 file's SELinux context or ACLs successfully set, nil otherwise.
1499 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1501 * w32proc.c (reader_thread): Avoid passing NULL handles to
1502 SetEvent and WaitForSingleObject.
1504 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1506 Port EXTERNALLY_VISIBLE to Clang 3.2.
1507 * conf_post.h (__has_attribute): New macro.
1508 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1510 2012-12-27 Glenn Morris <rgm@gnu.org>
1512 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1513 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1515 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1517 * fileio.c (file_name_as_directory, directory_file_name):
1518 Accept an additional argument MULTIBYTE to indicate whether the input C
1519 came from a multibyte or a unibyte Lisp string; all callers
1520 adjusted. Don't assume the input string is always multibyte.
1522 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1523 don't ENCODE_FILE them, and return a unibyte string if the input
1525 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1526 don't assume the input strings will always be multibyte. If the
1527 input strings are multibyte, decode strings obtained from C
1530 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1532 * lisp.h (toplevel): Add two notices to the comment about
1533 defining a new Lisp data type.
1534 * print.c (print_object): If Lisp_Save_Value object's pointer
1535 is the address of a memory area containing Lisp_Objects, try
1537 * alloc.c (valid_lisp_object_p): Adjust comment.
1539 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1541 * keyboard.c (record_asynch_buffer_change): Initialize an event
1542 only if it's really needed.
1543 * frame.h (enum output_method): Remove output_mac member since
1544 it's a leftover from the deleted code.
1545 * frame.c (Fframep): Adjust user here ...
1546 * terminal.c (Fterminal_live_p): ... and here.
1547 * coding.c (Qmac): Now here because it's only used to denote
1548 end-of-line encoding type.
1549 (syms_of_coding): DEFSYM it.
1550 * frame.h (Qmac): Remove duplicated declaration.
1552 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1554 * window.c (select_window_1): Now static, since it's used only here.
1556 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1558 * window.c (window_body_cols): Subtract display margins from the
1559 window body width on TTYs as well. See
1560 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1561 for the original report.
1563 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1565 * xdisp.c (redisplay_window): Remove inner local variable
1566 because the outer shadowed one has the same meaning.
1567 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1569 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1570 (xg_create_tool_bar): Adjust users.
1572 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1574 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1575 * buffer.c (Fget_buffer_create): Use it to set compact field of
1576 struct buffer_text to avoid accessing an uninitialized value
1577 when compact_buffer is called for the first time.
1578 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1579 (Fset_buffer_modified_p): Use buffer_window_count to check
1580 whether the buffer is displayed in some window.
1581 * xdisp.c (message_dolog): Likewise.
1583 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1585 * w32.c (acl_set_file): If setting the file security descriptor
1586 fails, and the new DACL is identical to the existing one, silently
1587 return success. This fixes problems for users backing up their
1588 own files without having the necessary privileges for setting
1589 security descriptors.
1591 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1593 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1594 after WaitForSingleObject returns normally. This expedites reader
1595 thread shutdown when delete_child triggers it.
1596 (reap_subprocess): More accurate commentary for why we call
1597 delete_child only when cp->fd is negative.
1599 * w32.c (sys_close): Do not call delete_child on a subprocess
1600 whose handle is not yet closed. Instead, set its file descriptor
1601 to a negative value, so that reap_subprocess will call
1602 delete_child on that subprocess when its SIGCHLD arrives.
1603 This avoids closing handles used for communications between sys_select
1604 and reader_thread, which doesn't give sys_select a chance to
1605 notice that the process exited and invoke the SIGCHLD handler for
1608 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1610 * nsfns.m (Fns_do_applescript): Run event loop until script has
1611 been executed (Bug#12969).
1612 (ns_run_ascript): Chech as_script for nil, set to nil after
1615 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1617 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1619 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1621 * w32term.c (w32fullscreen_hook): New function.
1622 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1624 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1626 * fileio.c (Finsert_file_contents): Doc fix.
1628 * w32proc.c (new_child, delete_child, find_child_pid): For a
1629 subprocess, consider its slot being in use as long as its process
1630 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1631 slot when a new process is started immediately after killing
1632 another one, without waiting enough time for the first process to
1633 be reaped and resources allocated for it be orderly freed.
1635 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1637 2012-12-21 Chong Yidong <cyd@gnu.org>
1639 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1641 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1643 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1645 * w32.c (get_name_and_id): Always pass NULL as the first argument
1646 of lookup_account_sid. Avoids crashes with UNC file names that
1647 refer to DFS domains, not to specific machine names. (Bug#12621)
1648 Remove now unused argument FNAME; all callers changed.
1649 (get_file_owner_and_group): Remove now unused argument FNAME; all
1652 2012-12-21 Chong Yidong <cyd@gnu.org>
1654 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1655 error for invalid chars, don't check for a nil return value.
1657 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1659 Avoid calls to CHAR_TO_BYTE if byte position is known.
1660 * editfns.c (make_buffer_string_both): Use move_gap_both.
1661 (Fbuffer_string): Use make_buffer_string_both.
1662 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1664 (buf_bytepos_to_charpos): Likewise.
1665 (charpos_to_bytepos): Remove.
1666 * fileio.c (Finsert_file_contents): Use move_gap_both.
1667 * search.c (Freplace_match): Likewise.
1668 * process.c (process_send_region): Likewise. Use convenient
1669 names for byte positions.
1670 * lisp.h (charpos_to_bytepos): Remove prototype.
1671 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1672 * insdel.c (move_gap): Likewise.
1674 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1676 * xdisp.c (redisplay_internal): Remove now-unused local.
1678 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1680 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1681 (redisplay_internal): Don't bother selecting the frame to get the
1682 proper value of frame-local variables (bug#13225).
1684 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1686 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1687 Rename 4th argument since it may be buffer or string. Adjust comment.
1688 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1690 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1692 * coding.c (Fdetect_coding_region): Do not check start and end with
1693 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1694 (code_convert_region): Likewise.
1696 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1698 * w32.c (acl_get_file, acl_set_file): Run the file name through
1699 map_w32_filename, and resolve any symlinks in the file name, like
1701 (acl_set_file): Call revert_to_self, if any privileges were
1704 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1706 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1707 ($(BLD)/w32.$(O)): Update dependencies.
1709 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1711 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1712 propagate redisplay's scrolling (if any) to the right window.
1713 (redisplay_internal): Use ensure_selected_frame.
1714 (display_mode_lines): Complete last fix.
1715 * window.c (select_window_1): New func, extracted from select_window.
1716 (select_window): Use it.
1717 * window.h (select_window_1): Declare.
1719 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1721 Emulate Posix ACL APIs on MS-Windows.
1722 * w32.c: Include sddl.h and sys/acl.h.
1723 (SDDL_REVISION_1): Define if not already defined.
1724 (g_b_init_get_security_descriptor_dacl)
1725 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1726 (g_b_init_is_valid_security_descriptor)
1727 (g_b_init_set_file_security): New static flags.
1728 (globals_of_w32): Initialize them to zero.
1729 (SetFileSecurity_Name): New string constant.
1730 (SetFileSecurity_Proc, GetSecurityDescriptorDacl_Proc)
1731 (ConvertStringSecurityDescriptorToSecurityDescriptor_Proc)
1732 (ConvertSecurityDescriptorToStringSecurityDescriptor_Proc)
1733 (IsValidSecurityDescriptor_Proc): New typedefs.
1734 (get_file_security, get_security_descriptor_owner)
1735 (get_security_descriptor_group): Set errno to ENOTSUP.

1738 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
1739 (acl_free, acl_get_file, acl_set_file): New functions.
1741 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1743 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1745 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1746 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1747 for some of that bug's symptoms can now cause Emacs to abort.
1748 Remove the workaround.
1749 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1750 The bug that caused SIGCHLD to get lost has been fixed, and the
1751 workaround for it can now cause Emacs to abort.
1753 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1755 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1756 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1757 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1759 2012-12-16 Romain Francoise <romain@orebokech.com>
1761 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1762 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1763 and copy ACL entries of file in addition to SELinux context if set.
1764 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1766 * Makefile.in (LIBACL_LIBS): New macro.
1769 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
1771 * fileio.c (internal_delete_file): Use bool for boolean.
1773 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1775 Fix bug #13079 on MS-Windows with temp files not being deleted.
1776 * w32.h (_child_process): New members input_file and
1778 (register_child): First argument is now pid_t.
1779 (record_infile, record_pending_deletion): New prototypes.
1781 * w32proc.c (new_child): Initialize input_file and
1782 pending_deletion members of the child.
1783 (delete_child): Delete the child's temporary input file, if any,
1784 that is pending deletion.
1785 (register_child): First argument is now pid_t.
1786 (record_infile, record_pending_deletion): New functions.
1787 (reap_subprocess): Fix a typo in DebPrint string.
1788 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1790 * fileio.c (internal_delete_file): Return an int again: non-zero
1791 if delete-file succeeds, zero otherwise.
1793 * lisp.h (internal_delete_file): Adjust prototype.
1795 * callproc.c (Fcall_process): Don't overwrite infile with result
1797 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1798 asynchronous subprocess, record the name of the input file name,
1800 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1801 delete the file, record it as pending deletion when the subprocess
1804 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1806 * editfns.c [HAVE_PWD_H]: Include grp.h.
1808 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1810 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1812 Fix permissions bugs with setgid directories etc. (Bug#13125)
1813 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1814 to mark it as a placeholder. The old value was often wrong.
1815 The only user of this attribute has been changed to use
1816 file-ownership-preserved-p instead, with its new group arg.
1817 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1819 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
1821 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
1822 Keep selected_window and selected_frame in sync.
1824 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1826 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1827 try to get accurate owner and group information from NT file
1828 security APIs. This is to make most callers of 'stat' and
1829 'lstat', which don't need that information, much faster.
1831 * dired.c (Ffile_attributes) [WINDOWSNT]:
1832 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1833 owner and group information from 'lstat'.
1835 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1837 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1838 as that confuses set-auto-coding, so insist on the head-read
1839 returning the full 1024 bytes. Let lseek compute the tail offset;
1840 less work for us. Do not ignore I/O errors when reading the tail.
1842 * xdisp.c: Minor style fixes.
1843 (init_iterator): Hoist assignment out of if-expression.
1844 (markpos_of_region): Callers now test for sign, not for -1.
1846 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
1848 Minor redisplay optimization when the region length is zero.
1849 * xdisp.c (markpos_of_region): New function.
1850 (init_iterator): Do not highlight the region of zero length.
1851 (redisplay_window): Check whether the region is of non-zero length.
1852 (try_cursor_movement): Allow if the region length is zero.
1853 (try_window_reusing_current_matrix, try_window_id): Likewise.
1855 2012-12-13 Eli Zaretskii <eliz@gnu.org>
1857 * search.c (search_buffer): Check the inverse translations of each
1858 character in pattern when the buffer being searched is unibyte.
1861 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1863 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1864 files, fixing a regression from 24.2.
1865 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1867 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1869 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1870 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1871 Remove unnecessary S_ISLNK test, as (contra the comments) this

2106 * dbusbind.c (Fdbus_init_bus):
2108 * xterm.c (x_term_init):

2119 no longer needed here.
2120 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2121 Move to inside set_time_zone_rule; they don't need file scope any more.
2122 (set_time_zone_rule): Maintain the TZ=value string separately.
2123 (syms_of_editfns): Don't initialize initial_tz;
2124 init_editfns now does it.
2125 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.

2143 Simplify get_lim_data.
2144 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2145 Remove USG and vlimit methods; no longer used these days.
2146 Add #error catchall just in case.
2148 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2149 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2150 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

2157 (abbr_to_signal): New static function.
2158 (Fsignal_process): Use it to convert signal names to ints.

2169 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>

2172 This will cause a production Emacs to dump core instead of
2175 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2177 * frame.c (make_frame): Do not set window's buffer to t.
2178 * window.c (Fsplit_window_internal): Likewise. Previously it was
2179 used to indicate that the window is being set up. Now we use
2180 set_window_buffer for all new windows, so the condition in ...
2181 (Fset_window_buffer): ... is always true and can be removed.
2183 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2185 Convenient macro to check whether the buffer is hidden.
2186 * buffer.h (BUFFER_HIDDEN_P): New macro.
2187 * frame.c (make_frame): Use it. Adjust comment.
2188 * buffer.c (candidate_buffer): New function.
2189 (Fother_buffer, other_buffer_safely): Use it.
2191 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2193 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2194 if the child process is still running. Instead, exit the wait
2195 loop and return zero. (Bug#13086)
2197 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2199 * frame.h (x_char_width, x_char_height): Remove prototypes.

2203 * nsfns.c (x_char_width, x_char_height): Likewise.
2204 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for

2210 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2212 Fix a recently-introduced delete-process race condition.
2213 * callproc.c, process.h (record_kill_process):
2214 New function, containing part of the old call_process_kill.
2215 (call_process_kill): Use it.
2216 This does not change call_process_kill's behavior.
2217 * process.c (Fdelete_process): Use record_kill_process to fix a
2218 race condition that could cause Emacs to lose track of a child.
2220 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2222 Avoid code duplication between prev_frame and next_frame.
2223 * frame.c (candidate_frame): New function. Add comment.
2224 (prev_frame, next_frame): Use it. Adjust comment.
2226 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2228 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2229 fails, signal an error instead of continuing with an empty
2231 Encode expanded temp file pattern before passing it to mkstemp or
2234 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2235 Encode the file name before passing it to dostounix_filename, in
2236 case it will downcase it (under w32-downcase-file-names).
2239 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2241 Minor call-process cleanups.
2242 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2243 at the same time as other platforms, to simplify analysis.
2244 No need for fd0_volatile since we have synch_process_fd.
2245 Avoid needless emacs_close; arg is always negative.
2247 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2249 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2252 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2254 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2255 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2256 and mouse_face_hidden members to a bitfields.

2258 (FRAME_SPACE_WIDTH): Remove.
2259 * nsterm.m, w32term.c, xterm.c: Adjust users.
2260 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2261 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2262 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2263 members to a bitfields.
2265 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2267 Don't let call-process be a zombie factory (Bug#12980).
2268 Fixing this bug required some cleanup of the signal-handling code.
2269 As a side effect, this change also fixes a longstanding rare race
2270 condition whereby Emacs could mistakenly kill unrelated processes,
2271 and it fixes a bug where a second C-g does not kill a recalcitrant
2272 synchronous process in GNU/Linux and similar platforms.
2273 The patch should also fix the last vestiges of Bug#9488,
2274 a bug which has mostly been fixed on the trunk by other changes.
2275 * callproc.c, process.h (synch_process_alive, synch_process_death)
2276 (synch_process_termsig, sync_process_retcode):
2277 Remove. All uses removed, to simplify analysis and so that
2278 less consing is done inside critical sections.
2279 * callproc.c (call_process_exited): Remove. All uses replaced
2280 with !synch_process_pid.
2281 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2282 These take the role of what used to be in unwind-protect arg.
2284 (block_child_signal, unblock_child_signal):
2285 New functions, to avoid races that could kill innocent-victim processes.
2286 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2287 (call_process_kill): Record killed processes as deleted, so that
2288 zombies do not clutter up the system. Do this inside a critical
2289 section, to avoid a race that would allow the clutter.
2290 (call_process_cleanup): Fix code so that the second C-g works again
2291 on common platforms such as GNU/Linux.
2292 (Fcall_process): Create the child process in a critical section,
2293 to fix a race condition. If creating an asynchronous process,
2294 record it as deleted so that zombies do not clutter up the system.
2295 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2296 light of these changes. Omit unnecessary call to emacs_close
2297 before failure, as the unwind-protect code does that.
2298 * callproc.c (call_process_cleanup):
2299 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2300 * process.c (record_deleted_pid): New function, containing
2301 code refactored out of Fdelete_process.
2302 (Fdelete_process): Use it.
2303 (process_status_retrieved): Remove. All callers changed to use
2304 child_status_change.
2305 (record_child_status_change): Remove, folding its contents into ...
2306 (handle_child_signal): ... this signal handler. Now, this
2307 function is purely a handler for SIGCHLD, and is not called after
2308 a synchronous waitpid returns; the synchronous code is moved to
2309 wait_for_termination. There is no need to worry about reaping
2310 more than one child now.
2311 * sysdep.c (get_child_status, child_status_changed): New functions.
2312 (wait_for_termination): Now takes int * status and bool
2313 interruptible arguments, too. Do not record child status change;
2314 that's now the caller's responsibility. All callers changed.
2315 Reimplement in terms of get_child_status.
2316 (wait_for_termination_1, interruptible_wait_for_termination):
2317 Remove. All callers changed to use wait_for_termination.
2318 * syswait.h: Include <stdbool.h>, for bool.
2319 (record_child_status_change, interruptible_wait_for_termination):
2321 (record_deleted_pid, child_status_changed): New decls.
2322 (wait_for_termination): Adjust to API changes noted above.
2324 * bytecode.c, lisp.h (Qbytecode): Remove.
2325 No longer needed after 2012-11-20 interactive-p changes.
2327 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2329 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2330 the scroll margin, move point outside the margin. (Bug#13055)
2332 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2334 * gtkutil.c (my_log_handler): New function.

2381 Fix xpalloc confusion after memory is exhausted.
2382 * alloc.c (xpalloc): Comment fix.
2383 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2384 and signals an error, do not clear charset_table_size, as
2385 charset_table is still valid.
2386 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2388 Use execve to avoid need to munge environ (Bug#13054).
2389 * callproc.c (Fcall_process):
2390 * process.c (create_process):
2391 Don't save and restore environ; no longer needed.
2392 * callproc.c (child_setup):
2393 Use execve, not execvp, to preserve environ.
2395 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2397 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2399 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2401 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2402 display for sliced images (Bug#10500).
2404 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.

2422 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2424 * callproc.c (Fcall_process): Don't misreport vfork failure.
2426 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2428 * callproc.c (Fcall_process): Fix vfork portability problems.
2429 Do not assume that fd[0], count, filefd, and save_environ survive
2430 vfork. Fix bug whereby wrong errno value could be reported for
2431 pipe failure. Some minor cleanups, too, as follows. Move buf and
2432 bufsize to the context where they're needed. Change new_argv to
2433 be of type char **, as this is more convenient and avoids casts.
2434 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2435 Now local constants, not macros.
2437 2012-11-18 Kenichi Handa <handa@gnu.org>
2439 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2440 for the variable "f".

2444 * font.c (font_unparse_xlfd): Exclude special characters from the
2445 generating XLFD name.

2487 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2488 between bpos_covered and bpos_max. This fixes cursor display when
2489 several display strings follow each other.
2491 * .gdbinit (pgx): If the glyph's object is a string, display the
2492 pointer to string data, rather than the value of the string object
2493 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2495 * indent.c (Fvertical_motion): If the starting position is covered
2496 by a display string, return to one position before that, to avoid
2497 overshooting it inside move_it_to. (Bug#12930)
2499 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2501 * frame.h (struct frame): Remove display_preempted member

2510 Drop unused pending_menu_activation member.
2511 * xterm.h (struct x_output): Drop outdated #if 0 code.
2512 Use bitfields for explicit_parent, asked_for_visible,
2513 has_been_visible and net_wm_state_hidden_seen members.

2517 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2518 of a literal "/". (Bug#12955)
2519 (gl-stamp): Invoke fc.exe directly, not through cmd.

2524 * dired.c: Assume HAVE_DIRENT_H.
2525 (NAMLEN): Remove, replacing with ...
2526 (dirent_namelen): New function. All uses changed. Use the GNU macro
2527 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2528 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2529 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2530 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2532 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2533 * ndir.h: Rename to ../nt/inc/dirent.h.
2534 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2535 Do not include <dirent.h>; no longer needed.
2536 * w32.c: Include <dirent.h> rather than "ndir.h".
2538 2012-11-23 Chong Yidong <cyd@gnu.org>
2540 * xftfont.c (xftfont_open): Remove duplicate assignment.
2542 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2544 * alloc.c (Fgarbage_collect): Unblock input after clearing
2545 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2546 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2547 * msdos.c (IT_frame_up_to_date): Use it here...
2548 * w32term.c (w32_frame_up_to_date): ...here...
2549 * xterm.c (XTframe_up_to_date): ...and here...
2550 * nsterm.m (ns_frame_up_to_date): ...but not here.
2551 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2553 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

2564 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2566 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2567 with Windows system header.
2569 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2571 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

2590 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2592 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2594 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2595 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2596 Define for the MSVC compiler.
2598 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2600 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2601 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2602 dostounix_filename. Prevents crashes down the road, because
2603 dostounix_filename assumes it gets a unibyte string.
2604 Reported by Michel de Ruiter <michel@sentient.nl>, see

2638 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2640 2012-11-19 Daniel Colascione <dancol@dancol.org>
2642 * w32fns.c (Fx_file_dialog):
2643 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2644 cygwin_convert_file_name*.
2646 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2647 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2649 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2651 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2653 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2655 * w32select.c: Include w32common.h before w32term.h, so that
2656 windows.h gets included before w32term.h uses some of its
2657 features, see below.
2659 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2661 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2665 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2667 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2668 (ns_select): Return at once if events are held (Bug#12834).

2672 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2673 Needed following 2012-10-20 change. (Bug#12902)
2675 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2677 * w32proc.c (waitpid): Remove unused label get_result.
2679 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2681 * makefile.w32-in (SYSWAIT_H): New macro.
2682 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2683 ($(BLD)/sysdep.$(O)): Update dependencies.

2689 * emacs.c, term.c (O_RDWR): Remove.
2690 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2691 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2692 * nsterm.m: Assume <fcntl.h> exists.
2693 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2694 (create_pty, Fmake_network_process, server_accept_connection)
2695 (wait_reading_process_output, init_process_emacs):
2697 (wait_reading_process_output): Put in a special case for WINDOWSNT
2698 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2699 It's not clear this is needed, but it's a more-conservative change.
2700 (create_process): Assume FD_CLOEXEC.
2701 (create_process, create_pty): Assume O_NOCTTY.
2702 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2703 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2704 Omit if not DOS_NT, since F_GETFL is not defined there.
2705 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2706 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2708 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2709 lack it, since gnulib guarantees this.
2710 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2712 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2714 * w32.c (faccessat): Pretend that directories have the execute bit
2715 set. Emacs expects that, e.g., in files.el:cd-absolute.
2717 * w32proc.c (create_child): Don't clip the PID of the child
2718 process to fit into an Emacs integer, as this is no longer a
2720 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2721 reaping only the process specified by PID argument, if that is
2722 positive. Use PID instead of dead_child to know which process to
2723 reap. Wait for the child to die only if WNOHANG is not in
2725 (sys_select): Don't set dead_child.
2727 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2728 as it is no longer needed.
2730 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2732 (record_child_status_change): Remove the setting of
2733 record_at_most_one_child for the !WNOHANG case.
2735 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2737 Fix problems in ns port found by static checking.
2738 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2739 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2740 not to process group.
2741 (ns_select): Use emacs_write, not write, as that's more robust
2742 in the presence of signals.
2743 (fd_handler:): Check for read errors.
2745 2012-11-16 Glenn Morris <rgm@gnu.org>
2747 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

2753 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2755 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2756 use the same value of thread handle.
2757 (start_timer_thread): If the timer thread exited (due to error),
2758 clean up by closing the two handles it used. Duplicate the caller
2759 thread's handle here, so it gets duplicated only once, when
2760 launching the timer thread. Set priority of the timer thread, not
2762 (getitimer): Don't duplicate the caller thread's handle here.
2765 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2767 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2770 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2772 Remove no-longer-used pty_max_bytes variable.
2773 * process.c (pty_max_bytes): Remove; unused.
2774 (send_process): Do not set it.
2776 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2778 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2779 Update dependencies.
2781 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2783 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2784 This follows up on the 2012-09-29 patch that removed indirection
2785 for the 'function' field. Reported by Sergey Vinokurov in
2786 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2788 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2790 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2791 different name, as the MS runtime does not have such a function,
2792 and probably never will.) All callers changed. Ignore DIRFD
2793 value if PATH is an absolute file name, to match Posix spec
2794 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2797 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2799 * xdisp.c (echo_area_display, redisplay_internal):
2800 Omit redundant check whether frame_garbaged is set.
2802 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2804 Use faccessat, not access, when checking file permissions (Bug#12632).
2805 This fixes a bug that has been present in Emacs since its creation.
2806 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2807 which must set some sort of record. (Torek's bug report was against
2808 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2809 same common flaw.) See Torek's Usenet posting
2810 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2811 Posted: Fri Apr 8 14:18:56 1983.
2812 * Makefile.in (LIB_EACCESS): New macro.
2814 * callproc.c (init_callproc):
2815 * charset.c (init_charset):
2816 * fileio.c (check_existing, check_executable, check_writable)
2818 * lread.c (openp, load_path_check):
2819 * process.c (allocate_pty):
2821 Use effective UID when checking permissions, not real UID.
2822 * callproc.c (init_callproc):
2823 * charset.c (init_charset):
2824 * lread.c (load_path_check, init_lread):
2825 Test whether directories are accessible, not merely whether they exist.
2826 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2827 * fileio.c (check_existing, check_executable, check_writable)
2829 Use symbolic names instead of integers for the flags, as they're
2831 (check_writable): New arg AMODE. All uses changed.
2832 Set errno on failure.
2833 (Ffile_readable_p): Use faccessat, not stat + open + close.
2834 (Ffile_writable_p): No need to call check_existing + check_writable.
2835 Just call check_writable and then look at errno. This saves a syscall.
2836 dir should never be nil; replace an unnecessary runtime check
2837 with an eassert. When checking the parent directory of a nonexistent
2838 file, check that the directory is searchable as well as writable, as
2839 we can't create files in unsearchable directories.
2840 (file_directory_p): New function, which uses 'stat' on most platforms
2841 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2842 (Ffile_directory_p, Fset_file_times): Use it.
2843 (file_accessible_directory_p): New function, which uses a single
2844 syscall for efficiency.
2845 (Ffile_accessible_directory_p): Use it.
2846 * xrdb.c (file_p): Use file_directory_p.
2847 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2848 * lread.c (openp): When opening a file, use fstat rather than
2849 stat, as that avoids a permissions race. When not opening a file,
2850 use file_directory_p rather than stat.
2851 (dir_warning): First arg is now a usage string, not a format.
2852 Use errno. All uses changed.
2853 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2854 that merely introduced a race.
2855 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2856 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2857 and similarly for the other O_* flags.
2858 * w32.c (sys_faccessat): Rename from sys_access and switch to
2859 faccessat's API. All uses changed.
2860 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2861 (magic_db): Rename from magic_file_p.
2862 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2863 char *, so that we don't have to test for file existence
2864 separately from opening the file for reading. This removes a race
2865 fixes a permission-checking problem, and simplifies the code.
2867 (file_p): Remove; no longer needed.
2869 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2871 Omit glyphs initialization at startup.
2872 * dispnew.c (glyphs_initialized_initially_p): Remove.
2873 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2874 (Fredraw_frame): Move actual code from here...
2875 (redraw_frame): ...to here. Add eassert. Adjust comment.
2876 (Fredraw_display): Use redraw_frame.
2877 * xdisp.c (clear_garbaged_frames): Likewise.
2879 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2881 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2882 passed to pint2str and pint2hrstr to be at most the size of the
2883 frame's decode_mode_spec_buffer. This avoids crashes with very
2884 large values of FIELD_WIDTH argument to decode_mode_spec.
2887 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2889 Fix a race with verify-visited-file-modtime (Bug#12863).
2890 Since at least 1991 Emacs has ignored an mtime difference of no
2891 more than one second, but my guess is that this was to work around
2892 file system bugs that were fixed long ago. Since the race is
2893 causing problems now, let's remove that code.
2894 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2895 whose time stamp is off by no more than a second. Insist that the
2896 file time stamps match exactly.
2898 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2900 * frame.h (struct frame): Convert external_tool_bar member to
2901 1-bit unsigned bitfield.

2903 all users are long dead. Adjust comment on mouse_position_hook.
2905 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2907 Simplify by using FOR_EACH_FRAME here and there.
2908 * frame.c (next_frame, prev_frame, other_visible_frames)
2909 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2910 * w32term.c (x_window_to_scroll_bar): Likewise.
2911 * window.c (window_list): Likewise.
2912 * xdisp.c (x_consider_frame_title): Likewise.
2913 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2914 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2915 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2916 * xmenu.c (menubar_id_to_frame): Likewise.
2917 * xselect.c (frame_for_x_selection): Likewise.
2918 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2919 (x_window_to_menu_bar): Likewise.
2920 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2922 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2924 * data.c (Qdefalias_fset_function): Now static.
2926 Another tweak to vectorlike_header change.
2927 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2928 Remove, and replace all uses with ...
2929 (next_in_free_list, set_next_in_free_list):
2930 New functions, which respect C's aliasing rules better.
2932 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2934 * window.c (list4i): Rename from 'quad'. All uses changed.
2935 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2937 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2939 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2940 warning about mixing declarations and code in ISO C90.
2942 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2944 * window.c (Fsplit_window_internal): Set combination limit of
2945 new parent window to t iff Vwindow_combination_limit is t;
2946 fixing a regression introduced with the change from 2012-09-22.
2947 (Fset_window_combination_limit): Fix doc-string.
2949 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2951 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2952 amount when the scroll margins are too large. When scrolling
2953 backwards in the buffer, give up if cannot reach point or the
2954 scroll margin within a reasonable number of screen lines.
2955 Fixes point position in window under scroll-up/down-aggressively when
2956 point is positioned many lines beyond the window top/bottom.
2959 * ralloc.c (relinquish): If real_morecore fails to return memory
2960 to the system, don't crash; instead, leave the last heap
2961 unchanged and return. (Bug#12774)
2963 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2965 * lisp.h (AUTOLOADP): New macro.

2970 (Finteractive_form): Simplify.
2971 (Fquo): Don't insist on having at least 2 arguments.
2972 (Qdefalias_fset_function): New var.
2974 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2976 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2980 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2982 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2984 Fix recently introduced crash on MS-Windows (Bug#12839).
2985 * w32term.h (struct scroll_bar): Use convenient header.
2986 (SCROLL_BAR_VEC_SIZE): Remove.
2987 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2989 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2991 Tweak last vectorlike_header change.
2992 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2993 vectorlike object on the free list. This is introduced to avoid
2994 some (but not all) pointer casting and aliasing problems, see
2995 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2996 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3000 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3002 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3003 been removed, so remove them here also.
3005 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3007 * doc.c (Fdocumentation): Handle new property
3008 dynamic-docstring-function to replace the old ad-advice-info.
3010 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3012 * fns.c (Qeql, hashtest_eq): Now static.
3014 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3016 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3017 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3018 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3019 * buffer.c (compare_overlays): Use XLI rather than XHASH.

3024 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3025 * lisp.h (sxhash_combine): New inline function, with the contents
3026 of the old SXHASH_COMBINE.

3032 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3033 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3034 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3037 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3039 * image.c (xpm_make_color_table_h): Fix compiler error because
3040 make_hash_table changed.

3044 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3046 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3048 Use ad-hoc comparison function for the profiler's hash-tables.
3049 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3050 (make_log): Use them.
3051 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3052 call Fequal any more.

3062 (hash_lookup, hash_remove_from_table): Move assertion checking of
3063 hashfn result here. Check hash-equality before calling cmpfn.

3100 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3101 (Fmake_bool_vector): Likewise.
3102 (struct large_vector): New type to represent allocation unit for
3103 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3104 (large_vectors): Change type to struct large_vector.
3105 (allocate_vector_from_block): Simplify.
3106 (PSEUDOVECTOR_NBYTES): Replace with...
3107 (vector_nbytes): ...new function. Adjust users.

3128 * keyboard.c (event_to_kboard): Do not dereference
3129 frame_or_window field of SELECTION_REQUEST_EVENT
3130 and SELECTION_CLEAR_EVENT events (Bug#12814).

3135 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3136 such as Scroll Lock, if the respective keys are treated as
3137 function keys, not as modifiers. This avoids destroying non-ASCII

3140 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3142 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3144 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3146 Restore some duplicate definitions (Bug#12814).
3147 This undoes part of the 2012-11-03 changes. Some people build
3148 with plain -g rather than with -g3, and they need the duplicate
3149 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3150 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3151 Define as macros, as well as as enums or as constants.

3156 to keypad keys (Bug#12816).
3158 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3160 Minor adjustments of recently-changed frame functions.
3161 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3162 known to be a frame (we're in the FRAMEP branch).
3163 * lisp.h (Qframep): Remove decl. frame.h declares this.
3164 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3165 since they're meant for Lisp fixnum values.
3167 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3169 * window.c (Fwindow_combination_limit): Revert to the only
3170 required argument and adjust docstring as suggested in
3171 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3172 by Martin Rudalics <rudalics@gmx.at>.

3223 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3225 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.

3227 file descriptor 2 for standard error. (Bug#12805)
3229 2012-11-05 Chong Yidong <cyd@gnu.org>
3231 * process.c (wait_reading_process_output): Revert previous change.
3233 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3235 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3236 This removes code that has been obsolete since around 1990.
3237 * callproc.c (Fcall_process):
3239 * process.c (create_process):
3240 * term.c (dissociate_if_controlling_tty):
3241 Assume setsid exists.
3242 * callproc.c (child_setup): Assume setpgid exists and behaves as
3243 per POSIX.1-1988 or later.
3244 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3245 * emacs.c (shut_down_emacs):
3246 * sysdep.c (sys_suspend, init_foreground_group):
3247 Assume getpgrp behaves as per POSIX.1-1998 or later.
3248 * msdos.c (setpgrp): Remove.
3249 (tcgetpgrp, setpgid, setsid): New functions.
3250 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3251 * term.c (no_controlling_tty): Remove; unused.
3252 * w32proc.c (setpgrp): Remove.
3253 (setsid, tcgetpgrp): New functions.
3255 Simplify by assuming __fpending.
3256 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3257 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3258 Do not assume that __fpending's result fits in int.
3260 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3262 Remove EMACS_OUTQSIZE+sleep hack.
3263 * dispnew.c (update_frame_1): Remove hack for terminals slower
3264 than 2400 bps, which throttled Emacs by having it sleep.
3265 This code hasn't worked since at least 2007, when the multi-tty stuff
3266 was added, and anyway those old terminals are long dead.
3267 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3268 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3270 Fix data-loss with --version (Bug#9574).
3271 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3272 as we can't assume that emacs_strerror is initialized, and strerror
3273 is good enough here.
3274 (main): Invoke atexit earlier, to catch earlier instances of
3275 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3277 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3279 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3280 (keyDown): Remap keypad keys to X11 virtual key codes.
3282 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3284 Fix data-loss with --batch (Bug#9574).
3285 * emacs.c: Include <close-stream.h>.
3286 (close_output_streams): New function.
3287 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3288 and handles errors appropriately.
3289 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3292 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3293 The symptom is a diagnostic "GLib-WARNING **: In call to
3294 g_spawn_sync(), exit status of a child process was requested but
3295 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3296 waitpid(), so exit status can't be returned." The diagnostic
3297 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3298 The real bug is a race condition between Emacs and glib: Emacs
3299 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3300 so that glib can't find it. Work around the bug by invoking
3301 waitpid only on subprocesses that Emacs itself creates.
3302 * process.c (create_process, record_child_status_change):
3303 Don't use special value -1 in pid field, as the caller now must
3304 know the pid rather than having the callee infer it.
3305 The inference was sometimes incorrect anyway, due to another race.
3306 (create_process): Set new 'alive' member if child is created.
3307 (process_status_retrieved): New function.
3308 (record_child_status_change): Use it.
3309 Accept negative 1st argument, which means to wait for the
3310 processes that Emacs already knows about. Move special-case code
3311 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3312 processes that have already been waited for, by testing and
3313 clearing new 'alive' member.
3314 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3315 now does this internally.
3316 (handle_child_signal): Let record_child_status_change do all
3317 the work, since we do not want to reap all exited child processes,
3318 only the child processes that Emacs itself created.
3319 * process.h (Lisp_Process): New boolean member 'alive'.
3321 Omit duplicate definitions no longer needed with gcc -g3.
3322 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3323 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3324 Define only as macros. There's no longer any need to also define
3325 these symbols as enums or as constants, since we now assume
3326 gcc -g3 when debugging.
3328 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3330 * lisp.mk: Adjust comments to the fact that term/internal is now
3331 loaded from loadup.el.
3333 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3334 (msdos_fatal_signal): New function.
3335 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3338 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3339 for GCC versions before 4.
3340 (emacs_raise): Define to call msdos_fatal_signal.
3342 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3343 iterator when starting in the middle of a display or overlay
3346 2012-11-03 Chong Yidong <cyd@gnu.org>
3348 * process.c (wait_reading_process_output): Clean up the last
3351 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3353 * process.c (wait_reading_process_output): Avoid a race condition
3354 with SIGIO delivery (Bug#11536).
3356 2012-11-03 Chong Yidong <cyd@gnu.org>
3358 * buffer.c (cursor_type): Untabify docstring.
3360 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3362 * frame.h (struct frame): Drop can_have_scroll_bars member
3363 which is meaningless for a long time. Adjust comments.
3364 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3365 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3367 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3369 * window.c (decode_next_window_args): Update window arg after
3370 calling decode_live_window and so fix crash reported at
3371 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3372 by Juanma Barranquero <lekktu@gmail.com>.
3373 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3374 * font.c (Ffont_at): Likewise.
3376 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3378 * widget.c (resize_cb): New function.
3379 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3380 (EmacsFrameResize): Check if all is up to date before changing frame
3383 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3385 Implement backtrace output for fatal errors on MS-Windows.
3386 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3387 (BACKTRACE_LIMIT_MAX): New macro.
3388 (w32_backtrace): New function.
3389 (emacs_abort): Use w32_backtrace when the user chooses not to
3390 attach a debugger. Update the text of the abort dialog.
3392 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3394 Window-related stuff cleanup here and there.
3395 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3396 Use decode_any_window.
3397 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3398 * xdisp.c (Fformat_mode_line): Likewise.
3399 * font.c (Ffont_at): Use decode_live_window.
3400 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3401 * window.c (decode_next_window_args): Likewise.
3402 (decode_any_window): Remove static.
3403 * window.h (decode_any_window): Add prototype.
3404 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3405 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3408 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3410 Remove pad from struct input_event.
3411 * termhooks.h (struct input_event): Remove padding field.
3413 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3414 member is never cons for a long time. Adjust comment.
3415 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3416 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3417 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3418 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3420 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3422 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3424 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3426 Fix crash when using Emacs as commit editor for git (Bug#12697).
3427 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3428 and it is configured in conf_post.h.
3429 (Fcall_process): Don't invoke both setsid and setpgid; the former
3430 is enough, if it exists.
3431 * callproc.c (Fcall_process, child_setup):
3432 * process.c (create_process): Use setpgid.
3433 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3435 * dispnew.c (init_display): Initialize the foreground group
3436 if we are running a tty display.
3437 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3438 * lisp.h (init_foreground_group): New decl.
3439 * sysdep.c (inherited_pgroup): New static var.
3440 (init_foreground_group, tcsetpgrp_without_stopping)
3441 (narrow_foreground_group, widen_foreground_group): New functions.
3442 (init_sys_modes): Narrow foreground group.
3443 (reset_sys_modes): Widen foreground group.
3445 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3447 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3449 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3451 * minibuf.c (read_minibuf): Restore current buffer since
3452 choose_minibuf_frame calling Fset_frame_selected_window may
3453 change it (Bug#12766).
3455 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3457 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3459 2012-10-30 Kenichi Handa <handa@gnu.org>
3461 * font.c (Ffont_at): If WINDOW is specified and it is not
3462 displaying the current buffer, signal an error.
3464 2012-10-29 Daniel Colascione <dancol@dancol.org>
3466 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3467 In preparation for fixing bug#12739, move these functions from
3470 * coding.h, coding.c: ... to here, and compile them only when
3471 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3472 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3474 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3476 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3477 (timer_loop, getitimer, setitimer): Use it instead of
3478 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3480 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3483 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3485 * nsterm.m (NO_APPDEFINED_DATA): New define.
3486 (last_appdefined_event_data): New variable
3487 (last_appdefined_event): Remove.
3488 (ns_select): Initialize t from last_appdefined_event_data instead
3489 of [last_appdefined_event data1].
3490 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3491 remove last_appdefined_event (Bug#12698).
3493 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3495 * frame.c (x_set_font): Catch internal error.
3497 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3499 Avoid overflow in w32 implementation of interval timers.
3500 When possible, for ITIMER_PROF count only times the main thread
3502 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3503 'volatile ULONGLONG' types. All the other data which was
3504 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3505 (GetThreadTimes_Proc): New typedef.
3506 (w32_get_timer_time): New function, returns a suitable time value
3508 (timer_loop): Enter critical section when accessing ULONGLONG
3509 values of the itimer_data struct, as these accesses are no longer
3510 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3511 Remove unused variable.
3512 (init_timers): Initialize s_pfn_Get_Thread_Times.
3513 (start_timer_thread): Don't assign itimer->caller_thread here.
3514 (getitimer): Assign itimer->caller_thread here.
3515 (setitimer): Always call getitimer to get the value of ticks_now.
3516 (sys_spawnve): Avoid compiler warning about format mismatch.
3518 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3520 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3521 mouse movement events if the menu bar is active. This avoids
3522 producing a busy "hour-glass" cursor by Windows if the mouse
3523 pointer is positioned over a tooltip shown for some menu item.
3525 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3527 Don't assume process IDs fit in int.
3528 * emacs.c (shut_down_emacs) [!DOS_NT]:
3529 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3530 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3531 Use pid_t, not int, to store process IDs, as 'int'
3532 is not wide enough on a few platforms (e.g., AIX and IRIX).
3534 2012-10-23 Kenichi Handa <handa@gnu.org>
3536 The following change is to make face-font-rescale-alist work
3537 correctly for non-ASCII fonts.
3539 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3540 (font_open_for_lface): Handle Vface_font_rescale_alist.
3542 2012-10-23 Chong Yidong <cyd@gnu.org>
3544 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3546 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3548 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3550 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3552 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3555 2012-10-21 Glenn Morris <rgm@gnu.org>
3557 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3559 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3561 Port to OpenBSD 5.1.
3562 * frame.c (Fmouse_position, Fmouse_pixel_position):
3563 * xdisp.c (produce_stretch_glyph):
3564 Declare local vars only when they're needed.
3565 This is clearer and avoids a warning on OpenBSD about unused vars.
3566 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3567 This is safer, and avoids OpenBSD warnings about unused vars.
3568 * keyboard.c (record_menu_key): Remove unnecessary decl.
3569 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3570 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3571 as our definition clashes with OpenBSD's.
3572 * xfaces.c (load_face_colors, check_lface_attrs)
3573 (get_lface_attributes_no_remap, get_lface_attributes)
3574 (lface_fully_specified_p, x_supports_face_attributes_p)
3575 (tty_supports_face_attributes_p, face_fontset, realize_face)
3576 (realize_x_face, realize_tty_face):
3577 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3578 merely Lisp_Object *. This is more informative and avoids
3579 a warning on OpenBSD about accessing beyond an object's size.
3581 2012-10-20 Chong Yidong <cyd@gnu.org>
3583 * lread.c (Fload): Doc fix (Bug#12592).
3585 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3587 * font.c (Ffont_at): Fix previous change.
3589 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3591 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3592 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3595 * alloc.c (NSTATICS): Decrease to 0x800.
3597 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
3599 * fns.c (Fnreverse): Include the problem element when signaling an
3602 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
3604 * nsterm.m (ns_select): Check writefds before call to
3605 FD_ISSET (Bug#12668).
3607 2012-10-18 Daniel Colascione <dancol@dancol.org>
3609 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3610 (staticpro): If we run out of staticpro slots, die with an
3611 informative error instead of just calling emacs_abort.
3613 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3615 Fix two flaws reported by Dmitry Antipov.
3616 * window.c (Ftemp_output_buffer_show): Remove.
3617 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
3618 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
3620 2012-10-17 Eli Zaretskii <eliz@gnu.org>
3622 * makefile.w32-in ($(BLD)/w32.$(O)):
3623 ($(BLD)/vm-limit.$(O)):
3625 ($(BLD)/unexw32.$(O)):
3626 ($(BLD)/fileio.$(O)):
3627 ($(BLD)/dispnew.$(O)): Update dependencies.
3629 * w32term.h (w32_initialize_display_info, initialize_w32_display):
3632 * w32proc.c: Include ctype.h.
3634 * w32.h (init_environment, check_windows_init_file)
3635 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
3636 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
3637 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
3638 (sys_link): Add prototypes.
3640 * w32.c: Include w32select.h.
3641 (sys_access, e_malloc, sys_select): Add prototypes.
3642 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
3644 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
3646 * unexw32.c: Include lisp.h and w32.h.
3648 * term.c [WINDOWSNT]: Include w32term.h.
3650 * process.c [WINDOWSNT]: Add prototype of sys_select.
3652 * fileio.c [WINDOWSNT]: Include w32.h.
3654 * dispnew.c [WINDOWSNT]: Include w32.h.
3656 * cygw32.c (Fcygwin_convert_path_to_windows)
3657 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
3658 Lisp_Object values. (Bug#12661)
3660 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
3661 to Lisp_Object. (Bug#12661)
3663 2012-10-17 Kenichi Handa <handa@gnu.org>
3665 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
3668 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
3670 * buffer.c (Fkill_buffer): When unchaining the marker,
3671 reset its buffer pointer to NULL (Bug#12652).
3673 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
3675 Do not verify indirection counters of killed buffers (Bug#12579).
3676 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
3677 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
3679 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
3681 * alloc.c (Fmake_byte_code): Fix typo in comment.
3682 * print.c (print_interval): Define as static to match prototype.
3683 * indent.c (disptab_matches_widthtab, recompute_width_table):
3686 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
3688 * editfns.c (get_system_name): Remove.
3689 * lisp.h (get_system_name): Remove prototype.
3690 * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes.
3691 (get_environ_db): Use Vsystem_name. Avoid call to strlen.
3693 2012-10-15 Daniel Colascione <dancol@dancol.org>
3695 * dbusbind.c: Add comment explaining reason for previous change.
3697 2012-10-15 Martin Rudalics <rudalics@gmx.at>
3699 * window.c (Fwindow_end): Rewrite check whether cached position
3700 can be used (Bug#12600).
3701 (resize_frame_windows, grow_mini_window, shrink_mini_window):
3702 Set windows_or_buffers_changed.
3704 2012-10-15 Daniel Colascione <dancol@dancol.org>

3708 headers define to something incompatible.
3710 2012-10-14 Daniel Colascione <dancol@dancol.org>
3712 * image.c (init_tiff_functions, init_imagemagick_functions)
3713 (init_svg_functions): Fix cygw32 build break by using these
3714 functions only when WINDOWSNT _and_ HAVE_NTGUI.
3716 2012-10-14 Jan Djärv <jan.h.d@swipnet.se>
3718 * nsterm.m (ns_select): Count fd:s in writefs also (Bug#12422).

3731 * fileio.c: Formatting fixes.
3733 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
3735 Fix some stat-related races.
3736 * fileio.c (Fwrite_region): Avoid race condition if a file is
3737 removed or renamed by some other process immediately after Emacs
3738 writes it but before Emacs stats it. Do not assume that stat (or
3740 * image.c (slurp_file): Resolve the file name with fopen + fstat
3741 rather than stat + fopen.
3742 (pbm_read_file) [0]: Remove unused code with stat race.
3743 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
3744 Remove ineffective code with stat race.
3746 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

3759 is zero (Bug#12384).
3761 2012-10-12 Juanma Barranquero <lekktu@gmail.com>

3767 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
3769 * fileio.c (check_existing): New function.
3770 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
3771 instead of calling 'stat', when what's needed is to check whether
3772 a file exists. This avoids expensive system calls on MS-Windows.
3775 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
3777 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
3778 determine whether a file exists and is not a directory.
3780 * lisp.h (check_existing): Add prototype.
3782 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
3784 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

3824 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
3826 * marker.c (cached_modiff): EMACS_INT, not int.
3828 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
3829 instead of having a wrong decl.
3830 * nsmenu.m (waiting_for_input): Remove wrong decl.
3832 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

3865 Use bool for boolean.
3866 * keyboard.c (timers_run, swallow_events)
3867 (detect_input_pending_run_timers):
3868 * process.c (wait_reading_process_output):
3869 Use unsigned for counter where wraparound-on-overflow is desired,
3870 since unsigned is guaranteed to have that behavior and signed is not.
3871 (read_char): Use ptrdiff_t for string length.
3872 (get_input_pending): Remove first argument, since it was always
3873 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3874 and behave as if it had that value. Return new value of
3875 input_pending. All callers changed.
3876 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3877 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3879 * keymap.c (push_key_description): Omit last arg, which was always 1.
3880 All callers changed.
3882 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3884 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3898 * termopts.h (flow_control, meta_key): Remove unused decls.
3899 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3900 Don't include termopts.h.
3902 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3904 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3906 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3908 * commands.h (immediate_quit): Remove duplicate decl.
3910 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3912 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
3914 (nsfont_open): Remove setting of Vfonts_in_cache.
3915 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3917 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3919 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3920 match what GetLastError returns. Explain why the function is
3923 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3924 'is_tooltip_frame', to avoid confusion with its global namesake.
3926 2012-10-08 Daniel Colascione <dancol@dancol.org>
3928 * xdisp.c (start_hourglass): Call w32_note_current_window when
3929 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3930 build that caused Emacs to display the hourglass cursor forever.
3932 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3933 which is broken under remote desktop, calculate the number of
3934 colors available for a display based on the display's number of
3935 planes and number of bits per pixel per plane. (bug#10397).
3937 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3939 * nsfont.m (Vfonts_in_cache): New variable.
3940 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3941 are used. Add cached fonts to Vfonts_in_cache.
3942 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3944 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3946 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3948 (FONT_H): Define after FRAME_H.
3949 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3950 Update dependencies.
3952 * w32term.c: Remove leftover declaration of keyboard_codepage.
3954 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3956 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3957 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3958 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3959 (GLOBAL_SOURCES): Add cygw32.c.
3960 ($(BLD)/unexw32.$(O)):
3962 ($(BLD)/w32console.$(O)):
3963 ($(BLD)/w32fns.$(O)):
3964 ($(BLD)/w32heap.$(O)):
3965 ($(BLD)/w32menu.$(O)):
3966 ($(BLD)/w32proc.$(O)): Add w32common.h.
3968 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3970 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3972 2012-10-08 Daniel Colascione <dancol@dancol.org>
3974 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3975 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3976 accidental message numbering hole. Change other messages to
3979 * w32select.h (HAVE_W32SELECT): Remove.
3981 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3982 w32common.h instead of w32heap.h.
3984 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3985 (get_allocation_unit, get_processor_type, get_w32_major_version)
3986 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3987 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3988 (OS_NT, os_subtype, cache_system_info): Move declarations to
3991 * w32heap.c: Include w32common.h.
3992 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3993 (w32_minor_version, w32_build_number, w32_subtype):
3994 Remove duplicate definitions.
3996 * w32fns.c: Include w32common.h; include w32heap.h only in
3999 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4000 Use `report_file_error' instead of `error' in order to better
4001 inform users of what went wrong. Increase NTGUI_UNICODE file
4002 dialog box file name length to 32k, the maximum allowed by the NT
4005 * w32common.h: New file.
4006 (ROUND_UP, ROUND_DOWN, get_page_size)
4007 (get_allocation_unit, get_processor_type, get_w32_major_version)
4008 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4009 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4010 (OS_NT, os_subtype, cache_system_info): Move here.
4012 * unexw32.c, unexcw.c: Include w32common.h.
4014 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4015 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4016 to call syms_of_w32select.
4018 * cygw32.h: Remove obsolete EXFUN declarations.
4020 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4022 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4023 of w32inevt.o from SOME_MACHINE_OBJECTS.
4025 2012-10-08 Daniel Colascione <dancol@dancol.org>
4027 * image.c: Permanent fix for JPEG compilation issue --- limit
4028 jpeglib `boolean' redefinition to Cygwin builds.
4030 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4032 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4034 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4037 2012-10-08 Daniel Colascione <dancol@dancol.org>
4039 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4040 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4041 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4042 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4043 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4044 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4045 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4046 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4047 now a supported configuration.
4049 * Makefile.in: consolidate image variables into LIBIMAGE; add
4050 W32_OBJ and W32_LIBS. Compile new files.
4053 (_DebPrint) declare tracing facility for W32 debugging. We need
4054 to unify tracing later.
4056 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4057 unconditional use of W32 Unicode functions. Cygwin runs only on
4058 100% Unicode operating systems.
4060 * cygw32.c: New file. Define Cygwin-specific facilities.
4061 (Fcygwin_convert_path_to_windows)
4062 (Fcygwin_convert_path_from_windows): New user functions for
4063 accessing Cygwin path-munging routines.
4065 * cygw32.h: New file.
4066 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4067 UTF-16LE strings temporarily inside non-Lisp-visible string
4070 (w32_strerror): Just what it says on the tin.
4072 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4073 also run for Cygwin; both systems have the same problem with using
4074 GUI facilities in a forked child. Also call syms_of_cygw32,
4075 syms_of_w32select in correct places.
4077 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4078 needs fork-then-exec for daemon launching.
4080 * font.h: Include frame.h.
4082 * image.c: Use the image library cache machinery only when we're
4083 compiling for native WINDOWSNT; Cygwin can use shared libraries
4084 like any other Unixlike system.
4086 * keyboard.c: Clarify a comment regarding the input loop.
4088 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4089 functions directly instead of trying to detect at runtime that our
4090 host operating system supports them. We make this change for two
4091 reasons: Cygwin lacks support for the multibyte character
4092 conversion functions used by the legacy menu code, and Cygwin
4093 never needs to rely on non-Unicode APIs.
4095 * unexw32.c (hinst): Declare extern.
4097 * w32.c: Change header order;
4098 (w32_strerror): Move to w32fns.c because we need it for
4099 non-WINDOWSNT builds.
4101 * w32.h: Add #error macro to make sure we don't include w32.h for
4102 Cygwin builds. Remove w32select declarations.
4104 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4105 w32fns.c. w32console.c is WINDOWSNT-only.
4107 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4108 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4110 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4111 (w32_major_version, w32_minor_version, w32_build_number)
4112 (os_subtype, sound_type): Define here
4113 (w32_defined_color): Make color parameter const for consistency
4114 with other _defined_color functions.
4115 (w32_createwindow): Unconditionally call w32_init_class instead of
4116 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4117 through the code is complex and unnecessary because class
4118 registration is practically free.
4119 (w32_name_of_message): New EMACSDEBUG-only function.
4120 (Fset_message_beep): Move here
4121 (Fx_open_connection): Require that the display name for Windows be
4122 "w32" for consistency, emacsclient disambiguation, and maybe, one
4123 day, multi-window-system support.
4124 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4125 Cygwin files for W32 GUI facilities, since these clearly don't
4126 expect Cygwin names.
4127 (_DebPrint): Define.
4128 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4129 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4130 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4131 (w32_last_error): Remove.
4133 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4135 * w32heap.c (syspage_mask): Declare here.
4136 (cache_system_info): Remove.
4138 * w32inevt.c (faked_key): Define globally, not statically.
4139 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4140 (w32_console_toggle_lock_key): Move to w32fns.c.
4142 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4144 * w32proc.c (_DebPrint): Move to w32fns.c.
4145 * w32select.c: Include string.h, stdio.h for Cygwin.
4146 * w32select.h: New File.
4148 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4150 (w32_message_fd): New variable. Under Cygwin, holds the file
4151 descriptor the system used to tell us about pending thread
4154 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4155 that prevented compilation under non-WINDOWSNT systems.
4157 (w32_initialize): Open /dev/windows and assign it to
4158 w32_message_fd. Provide w32 feature.
4160 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4161 (WM_EMACS_INPUT_READY): add.
4162 (prepend_msg, w32_message_fd): Declare globally.
4165 (keyboard_handle): Use only when WINDOWSNT.
4166 (notify_msg_ready): New function. Posts a message to the main
4167 thread's message queue under CYGWIN, which wakes up the main
4168 thread from select(2) by making the /dev/windows file descriptor
4169 ready. Under WINDOWSNT, it sets an event the same way the old
4172 (post, prepend_msg): Actually call notify_msg_ready instead of
4173 setting the input event directly.

4177 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4178 but it still has blocs in it, don't return it to the system,
4179 instead of aborting. (Bug#12402)
4181 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4183 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

4216 Improve sys_siglist detection.
4217 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4218 defined as a macro, as is done in Solaris.
4219 (sys_siglist_entries): New macro.
4220 (save_strsignal): Use it.
4221 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4222 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4224 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4226 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4227 fullscreen/Fullscreen.
4229 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4230 tobar_height is new.
4232 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4233 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4234 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

4247 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4249 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4251 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4253 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4254 that time stamps of directories could also be changed.
4255 Don't request the too broad GENERIC_WRITE, only the more restrictive
4256 FILE_WRITE_ATTRIBUTES access rights.
4258 * fileio.c (Fset_file_times): Special-case ignoring errors for
4259 directories only on MSDOS, not on MS-Windows.
4261 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4263 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4265 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4267 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4268 see whether CreateFile failed.
4270 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4272 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4273 to avoid similar races.
4274 * keyboard.c (pending_signals): Now bool, not int.
4276 Port timers to OpenBSD, plus check for timer failures.
4277 OpenBSD problem reported by Han Boetes.
4278 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4280 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4281 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4282 like OpenBSD, which has timer_settime but does not declare it.
4283 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4284 whether to use itimerspec-related primitives. All uses of
4285 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4287 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4289 * profiler.c (handle_profiler_signal): Fix a malloc race
4290 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4292 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4294 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4296 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4298 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4299 consistent with the change in return value of 'safe_strsignal'.
4301 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4303 Prefer plain 'static' to 'static inline' (Bug#12541).
4304 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4305 (bidi_set_sor_type, bidi_push_embedding_level)
4306 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

4311 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4312 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4313 Now 'static', not 'static inline'.
4315 Count overruns when profiling; change units to ns.
4316 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4317 Give extra weight to samples after overruns, to attempt to count
4318 the time more accurately.
4319 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4320 the underlying primitives nominally do ns.
4321 (Fprofiler_cpu_start): Document the change. Mention that
4322 the sampling intervals are only approximate.
4324 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4326 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4328 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4329 case for the special 0 coding-system.
4331 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4332 (Fmake_overlay): Remove redundant tests.
4333 (fix_start_end_in_overlays): Remove redundant recentering.
4335 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4337 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4338 Update dependencies.
4340 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4342 Fix a malloc race condition involving strsignal.
4343 A signal can arrive in the middle of a malloc, and Emacs's signal
4344 handler can invoke strsignal, which can invoke malloc, which is
4345 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4346 Fix it by altering the signal handler so that it does not invoke
4348 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4349 * process.c (status_message): Use const pointer, in case strsignal
4350 is #defined to safe_strsignal.
4351 * sysdep.c (sys_siglist, init_signals): Always define and
4352 initialize a substitute sys_siglist if the system does not define
4353 one, even if HAVE_STRSIGNAL.
4354 (safe_strsignal): Rename from strsignal. Always define,
4355 using sys_siglist. Return a const pointer.
4356 * syssignal.h (safe_strsignal): New decl.
4357 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4359 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4361 * w32proc.c (timer_loop): Fix code that waits for timer
4362 expiration, to avoid high CPU usage.
4364 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4366 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4367 (sweep_weak_table): Remove redundant prototypes.
4369 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4371 * emacs.c: Move the inclusion of TERM_HEADER after including
4372 windows.h on WINDOWSNT. This avoids compilation problems with
4375 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4377 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4378 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4379 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4380 as the previous version used 'void *'.
4382 * ralloc.c (ROUNDUP): Fix last change.
4383 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4386 * w32proc.c <disable_itimers>: New static flag.
4387 (init_timers): Initialize it to zero, after creating the critical
4388 sections used by the timer threads.
4389 (term_timers): Set to 1 before deleting the critical sections.
4390 (getitimer, setitimer): If disable_itimers is non-zero, return an
4391 error indication without doing anything. Reported by Fabrice
4392 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4393 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4395 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4398 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4399 term_ntproc after all the other bookkeeping, to get timers working
4400 as long as possible.
4402 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4404 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4405 Suggested by Juri Linkov in
4406 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4408 Prefer plain 'static' to 'static inline' (Bug#12541).
4409 With static functions, modern compilers inline pretty well by
4410 themselves; advice from programmers often hurts as much as it helps.
4411 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4412 this change shrinks the text size of the Emacs executable by 1.1%
4413 without affecting CPU significantly in my benchmark.
4414 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4494 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4496 Revert the FOLLOW-SYMLINKS change for file-attributes.
4497 Doing it right would require several changes to Tramp, and there's
4498 not enough time to get that tested before the freeze today.
4499 * dired.c (directory_files_internal, Ffile_attributes):
4502 * frame.c (x_report_frame_params): Port better to wider ints.
4503 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4504 or that pointers can be printed in 15 decimal digits.
4505 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4541 * vm-limit.c (lim_data): Now size_t.
4542 (check_memory_limits): Adjust prototypes of real_morecore and
4543 __morecore to receive argument of type ptrdiff_t. Use size_t for

4612 Windows-specific code to display the hourglass mouse pointer is no
4614 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
4615 to hourglass timer expiration.
4616 (start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY):
4617 Remove, no longer used.
4618 (w32_note_current_window, show_hourglass, hide_hourglass):
4619 New functions, in support of hourglass cursor display similar to other
4621 (syms_of_w32fns): Don't initialize hourglass_timer.
4623 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
4625 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
4627 * w32.h (init_timers, term_timers): Add prototypes.
4629 2012-09-30 Kenichi Handa <handa@gnu.org>

4668 (EmacsFSWindow): New interface for fullscreen.
4670 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
4672 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
4674 2012-09-30 Chong Yidong <cyd@gnu.org>
4676 * fns.c (Frandom): Doc fix.
4678 2012-09-30 Martin Rudalics <rudalics@gmx.at>

4681 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
4683 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
4685 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
4686 Suggested by Eli Zaretskii in
4687 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
4689 2012-09-30 Eli Zaretskii <eliz@gnu.org>
4691 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
4692 HAVE_TIMER_SETTIME is defined.
4694 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
4696 Profiler improvements: more-accurate timers, overflow checks.
4697 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4698 signal.h, setjmp.h. Include systime.h instead.
4699 (saturated_add): New function.
4700 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
4701 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
4702 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
4704 (enum profiler_cpu_running): New enum.
4705 (profiler_cpu_running): Now of that enum type, not bool.
4706 All uses changed to store the new value.
4707 (handle_profiler_signal): Rename from sigprof_handler_1,
4708 for consistency with other handlers. Do not check whether
4709 cpu_log is a hash-table if garbage collecting, since it
4710 doesn't matter in that case.
4711 (deliver_profiler_signal): Rename from sigprof_handler,
4712 for consistency with other handlers.
4713 (setup_cpu_timer): New function, with much of what used to be in
4714 Fprofiler_cpu_start. Check for out-of-range argument.
4715 Prefer timer_settime if available, and prefer
4716 thread cputime clocks, then process cputime clocks, then
4717 monotonic clocks, to the old realtime clock. Use make_timeval
4718 to round more-correctly when falling back to setitimer.
4719 (Fprofiler_cpu_start): Use it.
4720 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4721 Don't assume that passing NULL as the 2nd argument of setitimer
4722 is the same as passing a pointer to all-zero storage.
4723 Ignore SIGPROF afterwards.
4724 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4725 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4726 non-fatal signal handlers. Ignore SIGPROF on startup.
4727 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4728 in profiler.c, since sysdep.c now uses it.
4730 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
4731 Suggested by Eli Zaretskii in
4732 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

4784 * character.h (MAYBE_UNIFY_CHAR): Remove.
4785 * charset.c, charset.h (maybe_unify_char): Now static.
4786 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4787 Since this stuff is now private to charset.c, there's no need for
4788 a public macro and no need to inline by hand.

4821 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4823 Prefer POSIX timers if available.
4824 They avoid a race if the timer is too close to the current time.

4852 * w32.h (Vlibrary_cache): Do not declare.
4854 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4856 * w32proc.c (sys_signal): Handle all signals defined by the
4857 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4858 handlers for signals supported by Windows. Don't override
4859 term_ntproc as the handler for SIGABRT.
4860 (sigaction): Rewrite to call sys_signal instead of duplicating its
4862 (sys_kill): Improve commentary.
4864 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4865 consistency with a signature of a signal handler. All callers
4867 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4868 install term_ntproc as a signal handler for SIGABRT, as that
4869 should be done by the dumped Emacs.
4871 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4873 * w32select.c (term_w32select): Protect against repeated
4874 invocation by setting clipboard_owner to NULL after calling
4877 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4878 and term_ntproc to their modified signatures.
4880 * character.c (char_string, string_char): Remove calls to

4892 when encountering an unknown bytecode.
4894 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4896 image.c, indent.c: Use bool for booleans.

4899 * image.c: Omit unnecessary static decls.
4900 (x_create_bitmap_mask, x_build_heuristic_mask):

4940 (interruptible_wait_for_termination):
4941 Move these decls from lisp.h to syswait.h, since they use pid_t.
4942 Needed on FreeBSD; see Herbert J. Skuhra in
4943 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

4990 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4992 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4993 fatal_error_backtrace.
4995 * w32proc.c (sys_kill): Undo last change: don't do anything when
4996 invoked to deliver SIGABRT to our own process. This is now
4997 handled by emacs_raise.
4999 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5001 * w32term.c (w32_read_socket): Remove leftover reference to
5002 interrupt_input_pending.
5004 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5006 Do not use SA_NODEFER.
5007 Problem reported by Dani Moncayo in
5008 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5010 * sysdep.c (emacs_abort): Do not reset signal handler.
5011 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5012 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5013 wanted even on POSIXish hosts, and it doesn't work on Windows.
5015 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5017 * xterm.c (x_term_init): Call fixup_locale before and after calling
5018 gtk_init (Bug#12392).
5020 2012-09-23 Chong Yidong <cyd@gnu.org>
5022 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5023 Vdynamic_library_alist.
5025 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5026 (Fgnutls_available_p): Caller changed.
5028 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5029 (Flibxml_parse_xml_region): Likewise.
5031 * dispextern.h (struct image_type): Remove arg from init function.
5033 * image.c (Finit_image_library, lookup_image_type)

5035 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5036 (init_tiff_functions, init_gif_functions, init_svg_functions):
5037 Arglist and w32_delayed_load calling convention changed.
5038 (gs_type): Remove init_gs_functions; there is no such function.
5039 (valid_image_p, make_image): Fix caller to lookup_image_type.
5041 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5043 Simplify and avoid signal-handling races (Bug#12471).
5045 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5046 Avoid recursive loop if there's a fatal error in the function itself.
5047 * atimer.c (pending_atimers):
5048 * blockinput.h: Don't include "atimer.h"; no longer needed.
5049 (interrupt_input_pending): Remove. All uses removed.
5050 pending_signals now counts both atimers and ordinary interrupts.
5051 This is less racy than having three separate pending-signal flags.
5052 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5054 Rename from their upper-case counterparts BLOCK_INPUT,
5055 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5056 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5057 This makes it easier to access volatile variables more accurately.
5058 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5059 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5060 that's more reliable if the code is buggy and sets
5061 interrupt_input_blocked to a negative value. All uses changed.
5062 * atimer.c (deliver_alarm_signal):
5063 Remove. No need to deliver this to the parent; any thread can
5064 handle this signal now. All uses replaced by underlying handler.
5065 * atimer.c (turn_on_atimers):
5066 * dispnew.c (handle_window_change_signal):
5067 * emacs.c (handle_danger_signal):
5068 * keyboard.c (kbd_buffer_get_event):
5069 Don't reestablish signal handler; not needed with sigaction.
5070 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5072 Rework to avoid unnecessary accesses to volatile variables.
5073 (UNBLOCK_INPUT_TO): Now a function.
5074 (totally_unblock_input, unblock_input): New decls.
5075 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5076 (init_data): Remove. Necessary stuff now done in init_signal.
5077 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5078 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5079 (fatal_error_code): Remove; no longer needed.
5080 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5081 it doesn't always backtrace. All uses changed. No need to reset
5082 signal to default, since sigaction and/or die does that for us now.
5083 Use emacs_raise (FOO), not kill (getpid (), FOO).
5084 (main): Check more-accurately whether we're dumping.
5085 Move fatal-error setup to sysdep.c
5086 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5087 * gtkutil.c (xg_get_file_name, xg_get_font):
5088 Remove no-longer-needed signal-mask manipulation.
5089 * keyboard.c, process.c (POLL_FOR_INPUT):
5090 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5091 * keyboard.c (read_avail_input): Remove.
5092 All uses replaced by gobble_input.
5093 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5094 (kbd_buffer_store_event_hold, gobble_input):
5095 (record_asynch_buffer_change) [USABLE_SIGIO]:
5096 (store_user_signal_events):
5097 No need to mess with signal mask.
5098 (gobble_input): If blocking input and there are terminals, simply
5099 set pending_signals to 1 and return. All hooks changed to not
5100 worry about whether input is blocked.
5101 (process_pending_signals): Clear pending_signals before processing
5102 them, in case a signal comes in while we're processing.
5103 By convention callers now test pending_signals before calling us.
5104 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5105 New functions, to support changes to blockinput.h.
5106 (handle_input_available_signal): Now extern.
5107 (reinvoke_input_signal): Remove. All uses replaced by
5109 (quit_count): Now volatile, since a signal handler uses it.
5110 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5111 All callers changed. Block SIGINT only if not already blocked.
5112 Clear sigmask reliably, even if Fsignal returns, which it can.
5113 Omit unnecessary accesses to volatile var.
5114 (quit_throw_to_read_char): No need to restore sigmask.
5115 * keyboard.c (gobble_input, handle_user_signal):
5116 * process.c (wait_reading_process_output):
5117 Call signal-handling code rather than killing ourselves.
5118 * lisp.h: Include <float.h>, for...
5119 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5120 (pending_signals): Now volatile.
5121 (syms_of_data): Now const if IEEE floating point.
5122 (handle_input_available_signal) [USABLE_SIGIO]:
5123 (terminate_due_to_signal, record_child_status_change): New decls.
5124 * process.c (create_process): Avoid disaster if memory is exhausted
5125 while we're processing a vfork, by tightening the critical section
5127 (send_process_frame, process_sent_to, handle_pipe_signal)
5128 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5130 (send_process): No need for setjmp/longjmp any more, since the
5131 SIGPIPE stuff is now gone. Instead, report an error if errno
5133 (record_child_status_change): Now extern. PID and W are now args.
5134 Return void, not bool. All callers changed.
5135 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5136 Remove. All uses removed. This bug should be fixed now in a
5138 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5139 and record the child status change directly. This avoids the
5140 need to futz with the signal mask.
5141 (process_fatal_action): Move here from emacs.c.
5142 (emacs_sigaction_flags): New function, containing
5143 much of what used to be in emacs_sigaction_init.
5144 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5145 caught by emacs, to make races less likely.
5146 (deliver_process_signal): Rename from handle_on_main_thread.
5148 (BACKTRACE_LIMIT_MAX): Now at top level.
5149 (thread_backtrace_buffer, threadback_backtrace_pointers):
5151 (deliver_thread_signal, deliver_fatal_thread_signal):
5152 New functions, for more-accurate delivery of thread-specific signals.
5153 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5154 (deliver_arith_signal): Handle in this thread, not
5155 in the main thread, since it's triggered by this thread.
5156 (maybe_fatal_sig): New function.
5157 (init_signals): New arg DUMPING so that we can be more accurate
5158 about whether we're dumping. Caller changed.
5159 Treat thread-specific signals differently from process-general signals.
5160 Block all signals while handling fatal error; that's safer.
5161 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5163 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5164 Ignore SIGPIPE unless batch.
5165 (emacs_backtrace): Output backtrace for the appropriate thread,
5166 which is not necessarily the main thread.
5167 * syssignal.h: Include <stdbool.h>.
5168 (emacs_raise): New macro.
5169 * xterm.c (x_connection_signal): Remove; no longer needed
5170 now that we use sigaction.
5171 (x_connection_closed): No need to mess with sigmask now.
5172 (x_initialize): No need to reset SIGPIPE handler here, since
5173 init_signals does this for us now.
5175 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5177 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5178 background rect may be larger (Bug#12245).
5180 2012-09-23 Chong Yidong <cyd@gnu.org>
5182 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5184 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5186 * .gdbinit: Just stop at fatal_error_backtrace.
5187 See Stefan Monnier's request in
5188 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5189 Remove no-longer-used query of system type.
5191 2012-09-22 Chong Yidong <cyd@gnu.org>
5193 * search.c (Freplace_match): Doc fix (Bug#12325).
5195 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5197 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5198 (Fline_end_position): Doc fix.
5200 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5202 2012-09-22 Chong Yidong <cyd@gnu.org>
5204 * dispextern.h (struct image_type): Add new slot, storing a type
5205 initialization function.
5207 * image.c (define_image_type): Call the image initializer function
5208 if it is defined. Arguments and return value changed.
5209 (valid_image_p, make_image): Callers changed.
5210 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5211 (gif_type, imagemagick_type, svg_type, gs_type):
5212 Add initialization functions.
5213 (Finit_image_library): Call lookup_image_type.
5214 (CHECK_LIB_AVAILABLE): Macro deleted.
5215 (lookup_image_type): Call define_image_type here, rather than via
5216 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5217 (syms_of_image): Move define_image_type calls for xbm_type and
5218 pbm_type to lookup_image_type.
5220 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5222 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5223 'idle_timers' from here ...
5224 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5225 lists, to avoid infloops when the timer does something stupid,
5226 like reinvoke itself with the same or smaller time-out.
5229 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5231 * window.c (Fsplit_window_internal): Handle only Qt value of
5232 Vwindow_combination_limit separately.
5233 (Qtemp_buffer_resize): New symbol.
5234 (Vwindow_combination_limit): New default value.
5237 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5239 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5240 the new overlay string. (Bug#10159)
5242 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5244 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5245 or that fprintf is async-signal-safe. POSIX doesn't require
5248 2012-09-22 Chong Yidong <cyd@gnu.org>
5250 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5253 2012-09-22 Kenichi Handa <handa@gnu.org>
5255 * composite.c (composition_reseat_it): Handle the case that a
5256 grapheme cluster is not covered by a single font (Bug#12352).
5258 2012-09-21 Chong Yidong <cyd@gnu.org>
5260 * image.c (define_image_type): Avoid adding duplicate types to
5261 image_types (Bug#12463). Suggested by Jörg Walter.
5263 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5265 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5266 (print_load_command_name): Add case LC_DATA_IN_CODE.
5267 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5269 2012-09-21 Glenn Morris <rgm@gnu.org>
5271 * eval.c (Frun_hook_with_args_until_success)
5272 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5274 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5276 * fileio.c (Ffile_selinux_context): Only call freecon when
5277 lgetfilecon succeeded.
5278 (Fset_file_selinux_context): Likewise. (Bug#12444)
5280 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5282 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5283 reordering, locate the cursor by calling set_cursor_from_row; if
5284 that fails, clear the desired glyph matrix before returning a
5285 failure indication to the caller. Fixes leaving garbled display
5286 when fast scrolling with a down-key. (Bug#12403)
5287 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5288 scrolling through multibyte text.
5290 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5292 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5293 calling mark_vectorlike since that's the one that marks the window.
5294 (mark_discard_killed_buffers): Mark the final cdr.
5295 * window.h (struct window): Move prev/next_buffers to the
5296 non-standard fields.
5297 * window.c (make_window): Initialize prev/next_buffers manually.
5299 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5301 Omit unused arg EXPECTED from socket hooks.
5302 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5303 * nsterm.m (ns_term_init):
5304 * termhooks.h (struct terminal.read_socket_hook):
5305 * w32inevt.c (w32_console_read_socket):
5306 * w32term.c (w32_read_socket):
5307 * xterm.c (XTread_socket):
5308 Omit unused arg EXPECTED. All callers changed.
5309 (store_user_signal_events): Return void, not int, since callers no
5310 longer care about the return value. All uses changed.
5312 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5314 * w32gui.h (XParseGeometry): Do not declare.
5316 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5318 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5319 Ignore 'expected'. See Eli Zaretskii in
5320 <http://bugs.gnu.org/12471#8> (last line).
5322 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5323 (XParseGeometry): Now static. Substitute extremal values for
5324 values that are out of range.
5326 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5328 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5330 * nsfns.m (XParseGeometry): Remove.
5331 (Fx_create_frame): Call x_set_offset to correctly interpret
5332 top_pos in geometry.
5334 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5335 (Fx_parse_geometry): If there is a space in string, call
5336 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5338 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5340 * search.c (scan_buffer): Use character positions in calls to
5341 region_cache_forward and region_cache_backward, not byte
5342 positions. (Bug#12196)
5344 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5345 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5347 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5348 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5349 emacs_blocked_malloc, now deleted.
5351 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5353 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5354 The workaround was for improving performance on Solaris 2.4, but
5355 is getting in the way now. Emacs will still work if someone is
5356 still running Solaris 2.4 in a museum somewhere; Sun dropped
5357 support for Solaris 2.4 in 2003.
5358 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5359 * process.c (create_process) [HAVE_WORKING_VFORK]:
5360 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5361 since Emacs no longer uses vfork on that platform.
5363 2012-09-17 Glenn Morris <rgm@gnu.org>
5365 * emacs.c: Use COPYRIGHT.
5367 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5369 Remove configure's --without-sync-input option (Bug#12450).
5370 When auditing signal-handling in preparation for cleaning it up,
5371 I found that SYNC_INPUT has race conditions and would be a real
5372 pain to fix. Since it's an undocumented and deprecated
5373 configure-time option, now seems like a good time to remove it.
5374 Also see <http://bugs.gnu.org/11080#16>.
5375 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5376 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5377 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5378 (malloc_hysteresis):
5379 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5380 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5381 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5382 (dont_register_blocks, bytes_used_when_reconsidered)
5383 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5384 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5385 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5386 Remove. All uses removed.
5387 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5388 implementation, one that depends on whether the new macro
5389 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5391 * atimer.c (run_timers, handle_alarm_signal):
5392 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5393 (handle_async_input, process_pending_signals)
5394 (handle_input_available_signal, init_keyboard):
5395 * nsterm.m (ns_read_socket):
5396 * process.c (wait_reading_process_output):
5397 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5398 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5400 * xterm.c (XTread_socket):
5402 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5403 * eval.c (handling_signal): Remove. All uses removed.
5404 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5405 All uses replaced with the SYNC_INPUT version.
5406 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5408 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5411 * font.c (Ffont_shape_gstring): Remove unused local.
5413 2012-09-16 Glenn Morris <rgm@gnu.org>
5415 * Makefile.in (clean): No longer run nextstep's clean.
5417 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5419 (ns-app): Move here from ns.mk, and simplify.
5420 (clean): Simplify nextstep entry.
5421 * ns.mk: Remove file.
5423 2012-09-17 Kenichi Handa <handa@gnu.org>
5425 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5426 not covert the last few charactes.
5428 2012-09-16 Kenichi Handa <handa@gnu.org>
5430 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5431 here, but just check the validity of glyphs in the glyph-string.
5433 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5435 * window.c (Fwindow_parameter, Fset_window_parameter):
5436 Accept any window as argument (Bug#12452).
5438 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5440 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5441 to ns_term_init to avoid memory leak.
5443 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5444 explicit retain/release.
5445 (ns_term_init): Only allow one display. Initialize outerpool and
5448 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5450 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5451 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5452 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5453 the Microsoft problem in a different way, by altering ../nt/config.nt.
5455 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5470 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5471 by lisp.h. This completes removal of setjmp.h inclusion
5472 erroneously announced in the previous commit. (Bug#12446)
5474 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5477 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5478 not defined as a macro. The latter happens on MS-Windows.
5481 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5483 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5484 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5485 Some instances of '#include <setjmp.h>' removed, if the
5486 only reason for the instance was because "lisp.h" was included.
5487 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5488 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5489 and _longjmp with the new symbols. Emacs already uses _setjmp if
5490 available, so this change affects only POSIXish hosts that have
5491 sigsetjmp but not _setjmp, such as some versions of Solaris and
5492 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5493 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5494 (png_load_body) [HAVE_PNG]:
5495 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5496 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5497 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5498 since PNG requires jmp_buf. This is the only exception to the
5499 general rule that we now use sys_setjmp and sys_longjmp.
5500 This exception is OK since this code does not change the signal
5501 mask or longjmp out of a signal handler.
5503 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5505 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5506 Include "syssignal.h", for 'main_thread'.
5508 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5510 Avoid out-of-range marker position (Bug#12426).
5511 * insdel.c (replace_range, replace_range_2):
5512 Adjust markers before overlays, as suggested by comments.
5513 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5514 Remove redundant check before calling offset_intervals.
5516 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5518 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5519 current buffer (Bug#12387).
5521 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5523 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5525 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5527 Use a more backwards-compatible timer format (Bug#12430).
5528 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5529 vector element, not from the 4th, since PSECS is now at the end.
5530 (Fcurrent_idle_time): Doc fix.
5532 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5534 Function to mark objects and remove killed buffers at once.
5535 * alloc.c (discard_killed_buffers): Rename to ...
5536 (mark_discard_killed buffers) ... new name. Add marking
5537 of remaining objects. Fix comment. Adjust users.
5538 (mark_object): Do not touch frame buffer lists here.
5539 * frame.c (delete_frame): Reset frame buffer lists here.
5541 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5543 Better workaround for GNOME bug when --enable-gcc-warnings.
5544 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5545 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5546 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5548 Simplify SIGIO usage (Bug#12408).
5549 The code that dealt with SIGIO was crufty and confusing, e.g., it
5550 played tricks like "#undef SIGIO" but these tricks were not used
5551 consistently. Simplify mostly by not #undeffing standard symbols,
5552 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5553 or not as we please) rather than "defined SIGIO" (standard symbol
5554 that we probably shouldn't #undef).
5555 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5556 Modules that need it can include it.
5557 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5558 * dispextern.h (ignore_sigio): New decl.
5559 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5560 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5561 * emacs.c (shut_down_emacs):
5562 * keyboard.c (kbd_buffer_store_event_hold):
5563 Use ignore_sigio rather than invoking 'signal' directly.
5564 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5566 (FIONREAD, SIGIO): Do not #undef.
5567 (tty_read_avail_input): Use #error rather than a syntax error.
5568 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5569 for I_PIPE, used by SETUP_SLAVE_PTY.
5570 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5571 * sysdep.c (croak): Remove; no longer needed. This bit of
5572 temporary code, with Fred N. Fish's comment that it's temporary,
5573 has been in Emacs since at least 1992!
5574 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5575 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5576 * syssignal.h (croak): Remove decl.
5577 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5578 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5579 now that we're termios-only.
5580 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5581 * term.c (dissociate_if_controlling_tty): Use #error rather than
5584 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5585 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5586 to work around GNOME bug 683906.
5587 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5588 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5589 This works around GCC bug 54561.
5591 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5593 More fixes for 'volatile' and setjmp/longjmp.
5594 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5595 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5596 (png_load_body) [HAVE_PNG]:
5597 (jpeg_load_body) [HAVE_JPEG]:
5598 New function, with most of the old parent function's body.
5599 (png_load) [HAVE_PNG]:
5600 (jpeg_load) [HAVE_JPEG]:
5601 Invoke the new function, to avoid longjmp munging our locals.
5602 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5603 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5604 longjmp is passed 2, as the C standard doesn't guarantee this.
5605 Instead, store the failure code into mgr->failure_code.
5607 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5609 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5610 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5611 (syms_of_keyboard): Remove support for unread-command-char.
5613 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5615 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5616 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5617 violation. (Bug#12426)
5619 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5621 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5623 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5625 * eval.c: Add `inhibit-debugger'.
5626 (Qinhibit_debugger): New symbol.
5627 (call_debugger): Bind it instead of Qdebug_on_error.
5628 (maybe_call_debugger): Test Vinhibit_debugger.
5629 (syms_of_eval): Define inhibit-debugger.
5630 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5631 (syms_of_xdisp): Remove inhibit-debug-on-message.
5633 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5635 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5636 If a nonvolatile local variable is written before a _longjmp to
5637 the frame containing the variable, and is read after the _longjmp,
5638 the value read is indeterminate. Some local variables of type
5639 'struct handler' and 'struct catchtag' are used in this way, so
5640 mark each of their slots as volatile if the slot can be set before
5641 _longjmp and read afterwards.
5642 * lisp.h (struct handler): var and chosen_clause are now volatile.
5643 (struct catchtag): val, next, and pdlcount are now volatile.
5645 * bidi.c (bidi_push_it, bidi_pop_it):
5646 * fns.c (copy_hash_table):
5647 * image.c (define_image_type):
5648 * keyboard.c (kbd_buffer_store_event_hold):
5649 * process.c (Fprocess_send_eof):
5650 * xfaces.c (x_create_gc) [HAVE_NS]:
5651 * xgselect.c (xg_select):
5652 Prefer assignment to memcpy when either will do.
5654 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5655 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5656 time an item is removed. No need to mark this function 'inline';
5657 the compiler knows better than we do.
5659 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5661 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5662 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5663 to change_frame_size (Bug#12388).
5664 (windowDidResize:): Pass YES to updateFrameSize.
5666 * nsterm.h: Add delay parameter to updateFrameSize.
5668 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5670 Discard killed buffers from deleted window and frame objects.
5671 This reduces an amount of references to killed buffers and
5672 helps GC to reclaim them faster.
5673 * alloc.c (discard_killed_buffers): New function.
5674 (mark_object): Use it for deleted windows and frames.
5675 (mark_object): If symbol's value is set up for a killed buffer
5676 or deleted frame, restore its global binding.
5677 * data.c (swap_in_global_binding): Add GC notice.
5678 (swap_in_symval_forwarding): Use convenient set_blv_where.
5679 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5680 * window.h: ... to here.
5682 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5684 Convenient macro to check whether the buffer is live.
5685 * buffer.h (BUFFER_LIVE_P): New macro.
5686 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5687 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5689 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5691 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5692 composition cases (Bug#12364).
5694 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5695 overhang of succeeding glyphs overlapping box cursor.
5697 * w32term.c (x_draw_glyph_string): Likewise.
5699 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5701 Simplify, document, and port floating-point (Bug#12381).
5702 The porting part of this patch fixes bugs on non-IEEE platforms
5703 with frexp, ldexp, logb.
5704 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5706 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5707 support, by removing commented-out code and briefly listing the
5708 C89 functions excluded. The commented-out stuff was confusing
5709 maintenance, e.g., we thought we needed cbrt but it was commented out.
5710 (logb): Remove decl; no longer needed.
5711 (isfinite): New macro, if not already supplied.
5712 (isnan): Don't replace any existing macro.
5713 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5714 are present on all C89 platforms.
5715 (Ffrexp): Do not special-case zero, as frexp does the right thing
5717 (Flogb): Do not use logb, as it doesn't have the desired meaning
5718 on hosts that use non-base-2 floating point. Instead, stick with
5719 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5720 frexp, to avoid getting an unspecified result.
5722 * xdisp.c (Qinhibit_debug_on_message): Now static.
5724 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5726 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5727 NSBezierPath (Bug#12131).
5729 2012-09-10 Chong Yidong <cyd@gnu.org>
5731 * fns.c (Fdelq, Fdelete): Doc fix.
5733 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5735 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5736 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5738 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5740 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5741 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5744 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5746 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5747 left fringe if the window has a left margin. This avoids leaving
5748 traces of the cursor because its leftmost pixel is not drawn over.
5750 * dispnew.c (update_window_line): When the left margin area of a
5751 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5752 that screen line. (Bug#12277)
5754 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5756 Assume C89 or later for math functions (Bug#12381).
5757 This simplifies the code, and makes it a bit smaller and faster,
5758 and (most important) makes it easier to clean up signal handling
5759 since we can stop worring about floating-point exceptions in
5760 library code. That was a problem before C89, but the problem
5761 went away many years ago on all practical Emacs targets.
5762 * data.c, image.c, lread.c, print.c:
5763 Don't include <math.h>; no longer needed.
5764 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5765 might be autoconfigured, as that never happens.
5767 * doprnt.c (DBL_MAX_10_EXP):
5768 * print.c (DBL_DIG):
5769 Remove. C89 or later always defines these.
5770 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5771 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5772 (arith_error, domain_error, domain_error2):
5773 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5774 no longer needed -- we simply return what C returns. All uses removed.
5775 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5777 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5778 Remove. All uses expanded, as these macros are no longer used
5779 more than once and are now more trouble than they're worth.
5780 (Ftan): Use tan, not sin / cos.
5781 (Flogb): Assume C89 frexp.
5782 (fmod_float): Assume C89 fmod.
5783 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5784 (init_floatfns): Remove. All uses removed.
5786 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5788 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5789 compositeToPoint for OSX < 10.6 (Bug#12390).
5791 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5793 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5794 This produces more-accurate results.
5796 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5798 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5799 changes (Bug#12088).
5801 2012-09-08 Chong Yidong <cyd@gnu.org>
5803 * syntax.c (Fstring_to_syntax): Doc fix.
5805 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5807 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5808 in the internal border.
5809 (x_set_window_size): Remove static variables and their usage.
5810 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5811 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5812 Remove fringe/internal border adjustment (Bug#11052).
5813 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5814 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5815 (ns_fix_rect_ibw): Remove.
5816 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5817 (ns_dumpglyphs_box_or_relief): Ditto.
5818 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5820 (ns_dumpglyphs_image): Ditto.
5821 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5823 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5824 their usage. Add fringe_extended_p and its use as in other terms.
5825 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5826 scroll bar was removed.
5827 (updateFrameSize): New function.
5828 (windowDidResize): Move code to updateFrameSize and call it.
5830 * nsterm.h (EmacsView): Add updateFrameSize.
5832 2012-09-07 Chong Yidong <cyd@gnu.org>
5834 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5836 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5838 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5840 More signal-handler cleanup (Bug#12327).
5841 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5842 Problem introduced when merging patches. Noted by Eli Zaretskii in
5843 <http://bugs.gnu.org/12327#67>.
5844 * floatfns.c: Comment fix.
5845 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5846 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5847 and anyway the declaration is harmless even if SIGDANGER is not defined.
5848 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5849 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5850 source files not surprisingly expected syssignal.h to define, or
5851 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5852 Include <sys/ioctl.h>, for FIONREAD.
5853 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5854 This eliminates a problem whereby other files mysteriously had
5855 to include "syssignal.h" before including "systty.h" if they
5856 wanted to use "#ifdef SIGIO".
5858 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5860 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5862 * w32.c (sigemptyset): Empty the set.
5863 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5865 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5867 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5869 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5870 (mark_object): Likewise for frame objects.
5872 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5874 * syssignal.h (handle_on_main_thread): Always declare,
5875 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5876 This ports to platforms without HAVE_PTHREAD.
5878 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5880 Signal-handler cleanup (Bug#12327).
5881 Emacs's signal handlers were written in the old 4.2BSD style with
5882 sigblock and sigmask and so forth, and this led to some
5883 inefficiencies and confusion. Rewrite these to use
5884 pthread_sigmask etc. without copying signal sets around. Also,
5885 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5886 'signal', and instead use functions that do not attempt to take
5887 over the system name space. This patch causes Emacs's text
5888 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5889 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5890 Do not include <signal.h> or "syssignal.h", as these
5891 modules do not use signals.
5892 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5893 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5894 Do not include <signal.h>, as "syssignal.h" does that for us now.
5895 * atimer.c (sigmask_atimers): New function.
5896 (block_atimers, unblock_atimers): New functions,
5897 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5899 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5900 no longer needed here.
5901 * emacs.c (main): Inspect existing signal handler with sigaction,
5902 so that there's no need to block and unblock SIGHUP.
5903 * sysdep.c (struct save_signal): New member 'action', replacing
5904 old member 'handler'.
5905 (save_signal_handlers, restore_signal_handlers):
5906 Use sigaction instead of 'signal' to save and restore.
5907 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5908 New function. All users of 'signal' modified to use set_sighandler
5909 if they're writeonly, and to use sys_signal if they're read+write.
5910 (emacs_sigaction_init, forwarded_signal): New functions.
5911 (sys_signal): Remove. All uses replaced by calls to sigaction
5912 and emacs_sigaction_init, or by direct calls to 'signal'.
5913 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5914 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5915 all uses replaced by pthread_sigmask etc. calls.
5916 * syssignal.h: Include <signal.h>.
5917 (emacs_sigaction_init, forwarded_signal): New decls.
5918 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5919 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5920 (sigmask, sys_sigmask): Remove; no longer needed.
5921 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5922 (sigblock, sigunblock, sigfree):
5923 (sigsetmask) [!defined sigsetmask]:
5924 Remove. All uses replaced by pthread_sigmask.
5925 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5926 no longer need to be replaced, and its typical old uses
5927 are now done via emacs_sigaction_init and sigaction.
5928 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5929 (sys_sigdel): Remove; unused.
5930 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5932 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5934 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5935 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5937 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5939 Explicitly mark buffer_defaults and buffer_local_symbols.
5940 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5941 mark_local_symbols here.
5942 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5943 since special buffers aren't marked here any more.
5944 (allocate_buffer): Chain new buffer with all_buffers here...
5945 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5947 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5948 (syms_of_buffer): Remove staticpro of the above.
5949 (init_buffer_once): Set names for buffer_defaults and
5950 buffer_local_symbols.
5952 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5954 Use bool for booleans in font-related modules.
5955 * font.c (font_intern_prop, font_style_to_value)
5956 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5957 (generate_otf_features, font_check_otf_features, font_check_otf)
5958 (font_match_p, font_list_entities, font_at):
5959 * fontset.c (fontset_id_valid_p, reorder_font_vector
5960 (fontset_find_font, Fset_fontset_font)
5961 (face_suitable_for_char_p) [0]:
5962 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5963 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5964 (m17n_flt_initialized, ftfont_shape_by_flt):
5965 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5966 * nsfont.m (nsfont_draw):
5967 * w32font.c (w32font_draw):
5968 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5969 Use bool for booleans.
5970 * font.h: Adjust to above API changes.
5971 (struct font, struct font_driver, struct font_driver_list):
5972 Use bool for booleans.
5973 (struct font): Remove useless member encoding_type.
5975 * fontset.c, xftfont.c: Omit unnecessary static decls.
5977 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5979 * alloc.c (mark_object): Revert window marking code
5980 since it's unsafe for the Fset_window_configuration.
5982 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5984 Fix race conditions with signal handlers and errno (Bug#12327).
5985 Be more systematic about preserving errno whenever a signal
5986 handler returns, even if it's not in the main thread. Do this by
5987 renaming signal handlers to distinguish between signal delivery
5988 and signal handling. All uses changed.
5989 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5990 * data.c (deliver_arith_signal): Rename from arith_error.
5991 * dispnew.c (deliver_window_change_signal): Rename from
5992 window_change_signal.
5993 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5994 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5995 * keyboard.c (deliver_input_available_signal): Rename from
5996 input_available_signal.
5997 (deliver_user_signal): Rename from handle_user_signal.
5998 (deliver_interrupt_signal): Rename from interrupt_signal.
5999 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6000 (deliver_child_signal): Rename from sigchld_handler.
6001 * atimer.c (handle_alarm_signal):
6002 * data.c (handle_arith_signal):
6003 * dispnew.c (handle_window_change_signal):
6004 * emacs.c (handle_fatal_signal, handle_danger_signal):
6005 * keyboard.c (handle_input_available_signal):
6006 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6007 * process.c (handle_pipe_signal, handle_child_signal):
6008 New functions, with the actual signal-handling code taken from the
6009 original respective signal handlers, sans the sporadic attempts to
6010 preserve errno, since that's now done by handle_on_main_thread.
6011 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6012 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6013 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6015 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6016 Move initialization of main_thread to sysdep.c's init_signals.
6017 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6018 our usage, and simplifies the mainline code.
6019 (record_child_status_change): New static function, as a helper
6020 for handle_child_signal, and with most of the old child handler's
6022 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6023 (handle_child_signal): Use the above.
6024 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6025 Moved here from emacs.c.
6026 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6027 code moved here from emacs.c's main function.
6028 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6029 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6030 This lets callers save and restore errno properly.
6032 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6034 Remove redundant or unused things here and there.
6035 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6036 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6037 * editfns.c (Fcompare_buffer_substrings): Likewise.
6038 * frame.h (struct terminal, struct font_driver_list):
6039 Remove redundant declarations.
6040 * window.h (Qleft, Qright): Likewise.
6042 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6044 Do not mark objects from deleted buffers, windows and frames.
6045 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6046 (mark_object): Likewise for windows and frames.
6048 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6050 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6051 buffer_defaults and buffer_local_symbols as valid objects.
6052 Return special value to denote them.
6054 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6056 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6057 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6058 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6059 (file_name_absolute_p, Fsubstitute_in_file_name):
6060 (check_executable, check_writable, Ffile_accessible_directory_p)
6061 (Fset_file_selinux_context, Fdefault_file_modes)
6062 (Finsert_file_contents, choose_write_coding_system)
6063 (Fwrite_region, build_annotations, a_write, e_write)
6065 * filelock.c (boot_time_initialized, get_boot_time)
6066 (get_boot_time_1, lock_file_1, within_one_second):
6067 * floatfns.c (in_float):
6068 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6069 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6070 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6071 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6072 * window.c (compare_window_configurations):
6073 Use bool for booleans.
6074 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6075 (Fdefault_file_modes): Now mode_t, not int, for modes.
6076 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6077 (internal_delete_file): Now returns void, not a (boolean) int,
6078 since nobody was looking at the return value.
6079 * lisp.h, window.h: Adjust to above API changes.
6081 * xdisp.c (set_message): Simplify and reindent last change.
6083 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6085 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6087 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6089 * eval.c (call_debugger): Make the function non-static so that we
6090 can call it from set_message.
6092 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6093 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6095 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6097 Give more-useful info on a fatal error (Bug#12328).
6098 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6099 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6100 of doing the work ourselves.
6101 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6102 do most of the work.
6103 (fatal_error_backtrace): New function, taken from the guts
6104 of the old fatal_error_signal, but with a new option to output
6106 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6107 info about the signal than just its number.
6108 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6109 * sysdep.c: Include <execinfo.h>
6110 (emacs_backtrace): New function, taken partly from the previous
6111 code of the 'die' function.
6112 (emacs_abort): Call fatal_error_backtrace rather than abort.
6114 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6116 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6117 eager (load-time) macro-expansion.
6118 * lisp.mk (lisp): Add macroexp.
6120 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6122 Simplify redefinition of 'abort' (Bug#12316).
6123 Do not try to redefine the 'abort' function. Instead, redo
6124 the code so that it calls 'emacs_abort' rather than 'abort'.
6125 This removes the need for the NO_ABORT configure-time macro
6126 and makes it easier to change the abort code to do a backtrace.
6127 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6128 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6129 Remove; sysdep.c's emacs_abort now takes its place.
6130 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6131 'abort' changed to use 'emacs_abort'.
6132 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6133 (abort) [!defined abort]: Rename to ...
6134 (emacs_abort): ... new name.
6135 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6136 the place of the old 'abort' in emacs.c.
6137 * w32.c, w32fns.c (abort): Do not #undef.
6138 * w32.c (emacs_abort): Rename from w32_abort.
6140 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6142 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6143 offsets[j].dv, since the y axis of the screen coordinates points
6144 down, while the y axis of the font definition coordinates points
6145 up. This fixes display of Arabic diacritics such as KASRA and
6146 KASRATAN. (Bug#11860)
6148 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6150 Be more systematic about _setjmp vs setjmp.
6151 * alloc.c (test_setjmp, mark_stack):
6152 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6153 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6154 (png_load, my_error_exit, jpeg_load):
6155 * process.c (send_process_trap, send_process):
6156 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6157 The underscored versions are up to 30x faster on some hosts.
6158 Formerly, the code used setjmp+longjmp sometimes and
6159 _setjmp+_longjmp at other times, with no particular reason to
6160 prefer setjmp+longjmp.
6162 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6164 Fix minor problem found by static checking.
6165 * buffer.c (Fdelete_all_overlays): Return nil.
6167 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6169 * buffer.c (Fdelete_all_overlays): New function.
6171 2012-09-03 Chong Yidong <cyd@gnu.org>
6173 * gtkutil.c: Add extern decl for Qxft.
6175 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6177 * emacs.c, eval.c: Use bool for boolean.
6178 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6179 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6180 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6181 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6182 (main, decode_env_path, Fdaemon_initialized):
6183 * eval.c (call_debugger, Finteractive_p, interactive_p):
6184 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6185 (maybe_call_debugger, Fbacktrace):
6186 * process.c (read_process_output, exec_sentinel):
6187 Use bool for booleans.
6188 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6189 All callers changed.
6190 * eval.c (interactive_p): Omit always-true boolean argument
6191 EXCLUDE_SUBRS_P. All callers changed.
6192 * dispextern.h, lisp.h: Reflect above API changes.
6193 * firstfile.c (dummy): Use the address of 'main', whose signature
6194 won't change, instead of the address of 'initialize', whose
6195 signature just changed from int to bool.
6196 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6197 * msdos.c (fatal_error_in_progress): ... from here.
6198 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6200 (redisplay_internal, unwind_redisplay): Simply clear
6201 REDISPLAYING_P when unwinding, instead of saving its previous,
6202 always-false value and then restoring it.
6204 Clean up some extern decls.
6205 Mostly, this hoists extern decls out of .c files and into .h files.
6206 That way, we're more likely to catch errors if the interfaces change.
6207 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6208 declare xg_mark_data.
6209 * dispextern.h (x_frame_parm_handlers):
6211 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6212 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6213 (Qultra_bold, Qoblique, Qitalic):
6214 Move extern decl here from .c file.
6215 * alloc.c (xg_mark_data) [USE_GTK]:
6217 * eval.c (Qlexical_binding):
6218 * fns.c (time) [!HAVE_UNISTD_H]:

6224 * process.c (QCfamily, QCfilter):
6225 * widget.c (free_frame_faces):
6226 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6227 * xfont.c (x_clear_errors):
6228 * xterm.c (x_frame_parm_handlers):
6229 Remove now-redundant extern decls.
6230 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6231 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6233 * xfaces.c: Remove unnecessary static decls.
6234 * xterm.c (updating_frame): Remove decl of nonexistent object.
6236 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6237 when building globals.h, as the objects that are not built on
6238 this host are not needed to compile C files on this host.
6240 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6242 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
6244 * frame.h: Add missing prototype for x_wm_set_size_hint.
6246 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6250 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6251 (Fsubstitute_command_keys):

6256 (make_buffer_string, make_buffer_string_both)
6257 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

6271 Use bool for boolean.
6272 * intervals.h, lisp.h, systime.h: Reflect above API changes.

6275 2012-09-02 Chong Yidong <cyd@gnu.org>
6277 * keymap.c (push_key_description): Print M-TAB as C-M-i
6280 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6282 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6283 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

6288 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
6290 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6292 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6293 more than one grapheme cluster passed to the shaper: compute the
6294 offset adjustment values separately for each cluster. (Bug#11860)
6296 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6297 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6298 about implicit conversions from integer to pointer.
6300 2012-09-01 Daniel Colascione <dancol@dancol.org>
6302 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6303 system used too early.
6305 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6307 Better seed support for (random).
6308 * emacs.c (main): Call init_random.
6309 * fns.c (Frandom): Set the seed from a string argument, if given.
6310 Remove long-obsolete Gentzel cruft.

6312 (init_random): New function.
6314 2012-09-01 Daniel Colascione <dancol@dancol.org>
6316 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
6317 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
6318 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
6319 x_wm_set_size_hint, x_query_colors, x_real_positions,
6320 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
6321 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
6322 all of which have been moved to common code.
6324 * xfaces.c: Include TERM_HEADER instead of listing all possible
6325 window-system headers.
6327 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
6330 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
6331 directly accessing frame internals.
6333 * w32font.h: Include font.h. Define syms_of_w32font and
6336 * process.c: Include TERM_HEADER instead of listing all possible
6337 window-system headers.
6339 * nsterm.h: Remove declarations now in frame.h.
6340 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
6342 * menu.c: Include TERM_HEADER instead of listing all possible
6343 window-system headers.
6345 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6348 * keyboard.c: Include TERM_HEADER instead of listing all possible
6349 window-system headers.
6351 * image.c: Include TERM_HEADER instead of listing all possible
6352 window-system headers. Declare Vlibrary_cache when compiling for
6355 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6356 window system declarations.
6358 * frame.h: Move common functions here: set_frame_menubar,
6359 x_set_window_size, x_sync, x_get_focus_frame,
6360 x_set_mouse_position, x_set_mouse_pixel_position,
6361 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6387 Remove mark_ttys function and fix tty_display_info initialization.
6388 * lisp.h (mark_ttys): Remove prototype.
6389 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6390 to mark_ttys because all possible values of 'top_frame' slot are
6391 the frames which are reachable from Vframe_list.
6392 * term.c (mark_ttys): Remove.
6393 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6395 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6397 Change struct frame bitfields from unsigned char to unsigned.

6401 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6402 bitfields from unsigned char to unsigned.

6406 Remove unused member of struct x_output and struct w32_output.
6407 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
6408 * w32term.h (struct w32_output): Likewise.
6410 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
6412 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
6413 does not become zero (Bug#12234).
6415 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6417 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6418 for GCC 4.7.1 x86-64.

6423 source directory's site-lisp dir to the load-path if it exists,
6424 consistent with in-tree builds. (Bug#12302)
6426 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6428 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
6429 button_values to NULL. Call setStykeMask so dialogs get a close button.
6430 (windowShouldClose:): Set window_closed.
6431 (dealloc): New member, free button_values.
6432 (process_dialog:): Make member function. Remove window argument,

6442 Code formatting change.
6443 (timeout_handler:): Set timer_fired to YES.
6444 (runDialogAt:): Set timer_fired to NO.
6445 Handle click on close button as quit.
6447 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6448 Add window_closed and button_values. Add void as return value for
6449 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6450 Add process_dialog as new member.
6452 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6454 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6455 is not one of the heaps we manage. (Bug#12242)
6457 2012-08-28 Glenn Morris <rgm@gnu.org>
6459 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

6471 if the buffer is dead.
6472 (Fother_buffer, other_buffer_safely): Remove redundant
6475 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
6477 Always use set_buffer_if_live to restore original buffer at unwind.
6478 * buffer.h (record_unwind_current_buffer): New function.

6517 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6518 and remove last int (actually boolean) argument, which was always 0.
6519 All callers changed.
6520 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6521 * dispextern.h (struct composition_it): Use bool for boolean.
6522 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6523 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6524 * dired.c (file_name_completion):
6525 Use bool for boolean. (This was missed in an earlier change.)
6527 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6529 * window.c (Fset_window_configuration): Revert first part of
6532 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6534 * nsterm.h (NSPanel): New class variable dialog_return.
6536 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6537 Initialize dialog_return.
6538 (windowShouldClose:): Use stop instead of stopModalWithCode.
6539 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6540 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6542 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

6587 Use bool for booleans.
6588 * coding.h, lisp.h: Reflect above API changes.
6589 * coding.c: Remove unnecessary static function decls.
6590 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6591 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6592 not a boolean 'int', since callers never look at the return value.
6593 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6594 * coding.h (decoding_buffer_size, encoding_buffer_size)
6595 (emacs_mule_string_char): Remove unused extern decls.
6596 (struct iso_2022_spec, struct coding_system):

6602 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6604 Fix spare memory change (Bug#12286).
6605 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6606 (valid_lisp_object_p): Likewise.
6608 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6610 * window.c (Fset_window_configuration): Record any window's old
6611 buffer if it's replaced (see Bug#8789). If the new current
6612 buffer doesn't appear in the selected window, go to its old
6615 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6617 Special MEM_TYPE_SPARE to denote reserved memory.
6618 * alloc.c (enum mem_type): New memory type.
6619 (refill_memory_reserve): Use new type for spare memory.
6620 This prevents live_cons_p and live_string_p from incorrect
6621 detection of uninitialized objects from spare memory as live.
6623 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6626 * Makefile.in (.PHONY): versioclean -> versionclean.
6628 Remove unused external symbols.
6629 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6630 * window.c (Qwindow_valid_p, decode_valid_window):
6631 Now static, not extern.
6632 * data.c (Qinterval): Remove; unused.
6633 (syms_of_data): Do not define 'interval'.
6634 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6635 * window.h (decode_valid_window):

6649 (map_sub_char_table):
6650 Use bool for boolean.
6651 * character.c (str_to_unibyte): Omit last boolean argument; it was
6652 always 0. All callers changed.
6653 * character.h, charset.h: Adjust to match previous changes.
6654 * character.h (char_printable_p): Remove decl of nonexistent function.
6655 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6656 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6657 are all boolean, so make them single-bit bitfields.
6659 * lisp.h (ASET): Remove attempt to detect side effects.
6660 It was meant to be temporary and it often doesn't work,
6661 because when IDX has side effects the behavior of IDX==IDX
6662 is undefined. See Stefan Monnier in
6663 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6665 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6667 * lisp.h (functionp): New function (extracted from Ffunctionp).
6668 (FUNCTIONP): Use it.
6669 * eval.c (Ffunctionp): Use it.
6671 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6673 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6674 as that's faster and simpler than static storage. Don't bother
6675 with the g_main_context_query overhead if g_main_context_pending
6676 says no events are pending.
6677 (gfds, gfds_size): Remove these static vars.
6678 (xgselect_initialize): Remove; no longer needed.
6679 All uses and decls removed.
6681 * emacs.c (fatal_error_signal_hook): Remove.
6682 All uses removed. This leftover from old code was always 0.
6684 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6685 * casefiddle.c (casify_object, casify_region):
6686 * casetab.c (set_case_table):

6688 * category.h (CHAR_HAS_CATEGORY):
6689 Use bool for booleans, instead of int.
6691 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6693 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6695 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6697 On assertion failure, print backtrace if available.
6698 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6699 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6700 * Makefile.in (LIB_EXECINFO): New macro.
6703 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6704 * bytecode.c (exec_byte_code):
6705 * callint.c (check_mark, Fcall_interactively):
6706 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)

6708 * lisp.h (USE_SAFE_ALLOCA):
6709 Use bool for booleans, instead of int.
6710 * lisp.h, process.h: Adjust prototypes to match above changes.
6711 * callint.c (Fcall_interactively): Don't assume the mark's
6712 offset fits in 'int'.
6714 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>

6723 (mmap_enlarge, mmap_set_vars):
6724 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6725 Use bool for booleans, instead of int.
6726 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6727 since the 1-or-0 return value is always ignored anyway.
6728 (mmap_initialized_p):
6729 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6730 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6732 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6734 * bidi.c: Use bool for boolean.
6735 This is a bit more readable, and makes the text segment of bidi.o
6736 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6737 Presumably it's faster too.
6738 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

6745 Use bool for booleans, instead of int.
6746 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6747 (bidi_unshelve_cache): Adjust decls to match code.

6761 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6762 compile time tests instead of run time tests on systems that do
6764 (FRAME_MAC_P): Remove leftover from deleted code.
6765 * frame.c (syms_of_frame): Remove leftover from deleted code.
6767 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6769 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6771 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6773 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6774 Otherwise, the compiler complains about (A?B:C) where B is void
6775 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6776 (fontset_add): Return void, for FONTSET_ADD.
6778 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6780 * alloc.c: Use bool for booleans.
6781 (gc_in_progress, abort_on_gc)

6788 (mark_stack, valid_pointer_p, make_pure_string)
6789 (Fgarbage_collect, survives_gc_p, gc_sweep):
6790 Use bool for booleans, instead of int.
6791 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6792 Remove unused local.
6793 * alloc.c (PURE_POINTER_P):
6794 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.

6801 * lread.c (readchar, read1):
6802 * print.c (Fprin1_to_string):
6803 * xdisp.c (push_message):
6804 Use bool for booleans affected directly or indirectly by
6807 Make recently-introduced setters macros.
6808 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6809 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6810 (set_fontset_default, set_fontset_fallback): Rename from their
6811 upper-case counterparts, and make them functions rather than macros.
6812 This is more consistent with the other recently-introduced setters.
6813 These don't need to be inline, since they're local.
6815 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>

6820 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6822 * lisp.h (vcopy): Use memcpy rather than our own loop.
6823 This fixes a performance regression introduced by the recent
6824 addition of vcopy. This means 'vcopy' will need to be modified
6825 for a copying collector, but that's OK. Also, tighten the
6826 checking in the assertion.

6830 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6831 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6832 non-base glyph for the width of the base character, according to
6833 what x_draw_composite_glyph_string_foreground expects.
6834 Generate WADJUST value according to composition_gstring_width's
6835 expectations, to produce correct width of the composed character.
6836 Reverse the sign of the DU offset produced by ScriptPlace.
6838 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6840 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

6868 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6871 2012-08-20 Glenn Morris <rgm@gnu.org>
6873 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6874 Don't assume that `ln -f' works.
6876 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6878 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6879 and later about non-assignments with no effect. See discussion at
6880 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for

6905 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6906 (set_hash_key_and_value, set_hash_index, set_hash_next)
6907 (set_hash_hash): New functions.
6908 * charset.c, fns.c: Adjust users.

6920 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6922 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6924 Rely on <config.h> + <unistd.h> to declare 'environ',
6925 as gnulib does this if the system doesn't.
6926 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6927 Remove declaration. MS-Windows declares it on stdlib.h which is
6928 included by conf_post.h.
6929 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6930 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

6933 * unexaix.c, unexcoff.c: Include "mem-limits.h".

6937 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6939 2012-08-19 Chong Yidong <cyd@gnu.org>

6954 * nsfont.m (ns_ascii_average_width): Ensure the string
6955 ascii_printable is initialized with a null-terminated character

6961 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6962 Return void, not Lisp_Object. Otherwise, the compiler
6963 complains about (A?B:C) where B is void and C is Lisp_Object
6964 when compiling CHAR_TABLE_SET, due to the recent change to
6965 the API of sub_char_table_set_contents.

7797 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7798 * w32.c (init_environment): Change the default values of many
7799 environment variables in dflt_envvars[] to NULL, to avoid pushing
7800 them into environment when they were not already defined.
7801 Remove the code that deletes site-lisp subdirectories from the default
7802 value of EMACSLOADPATH, as it is no longer needed.
7803 (check_windows_init_file): Now external, not static.
7804 Use Vload_path as is, without adding anything, as this function is now
7805 called when Vload_path is already set up.
7807 * w32.h (check_windows_init_file): Add prototype.
7809 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
7810 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
7811 compatibility with Posix platforms.
7812 (main): Move the call to check_windows_init_file to here from
7814 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
7815 any, in the DEFALT argument into the root of the Emacs build or
7816 installation tree, as appropriate.
7818 * callproc.c (init_callproc_1): Call decode_env_path instead of
7819 doing its equivalent by hand.
7820 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
7821 the code that sets Vexec_path run on MS-Windows.
7823 * lread.c (init_lread): Add comments to #ifdef's.
7825 * msdos.c (dos_set_window_size, IT_update_begin)

7833 Now constants, not macros.
7835 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
7837 Remove unnecessary casts involving pointers.
7838 These casts are no longer needed now that we assume C89 or later,
7839 since they involve casting to or from void *.

7852 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7853 Remove unnecessary pointer casts.
7854 * alloc.c (record_xmalloc): New function.
7855 * lisp.h (record_xmalloc): New decl.
7856 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7857 more like a function. This is because the pointer cast is not
7858 needed. All uses changed.
7859 * print.c (print_string, print_error_message): Avoid length recalc.
7861 Improve fix for macroexp crash with debugging (Bug#12118).
7862 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7863 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7864 not supposed to be invoked from the garbage collector.
7865 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7866 (gc_aset): New function, which is like ASET but can be
7867 used in the garbage collector.
7868 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7883 headers (most versions of MinGW w32api don't).
7884 (get_security_info, create_symbolic_link)
7885 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7887 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7888 in the argument file name.

7892 have the required privileges.
7893 (get_file_security_desc_by_name): Rename from
7894 get_file_security_desc.

7896 with addition of handling of symlinks and support for 'lstat'.
7897 If possible, get file's attributes and security information by
7898 handle, not by name. Produce S_IFLNK bit for symlinks, when
7899 called from 'lstat'.
7900 (stat, lstat): New functions, call 'stat_worker'.
7901 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7902 symlinks when the underlying filesystem supports them.
7904 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7906 Fix macroexp crash on Windows with debugging (Bug#12118).
7907 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7908 checking subscripts; problem introduced with the recent
7909 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7910 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7911 since it's used in non-static inline functions now.
7913 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7914 Don't assume buffer size fits in 'int'. Remove unused local.

7931 * category.c (CATEGORY_INLINE):
7932 * character.c (CHARACTER_INLINE):
7933 * charset.c (CHARSET_INLINE):
7934 * composite.c (COMPOSITE_INLINE):
7935 * dispnew.c (DISPEXTERN_INLINE):
7936 * sysdep.c (SYSTIME_INLINE):
7937 Define to EXTERN_INLINE, so that the corresponding functions
7938 are compiled into code.
7939 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7940 (INLINE_HEADER_END): New macros.
7941 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7961 hard-coding the path separator.
7963 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7965 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7966 This how ASET and AREF are supposed to work, and makes
7967 it easier to think about future improvements. See
7968 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7969 * charset.h (set_charset_attr): New function.

8222 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
8223 does that unconditionally. Remove file, which is now empty.
8225 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
8228 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

8349 w32_console_unicode_input.
8350 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8351 (w32_kbd_patch_key, key_event): Use the codepage returned by
8352 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

8384 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8385 enumeration constants, as PURE and HEAP are too general, and clash
8386 with other headers and sources, such as gmalloc.c and the
8387 MS-Windows system headers. All users changed.
8389 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8391 Revert last save_excursion_save and save_excursion_restore changes.
8392 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8405 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8406 arms of an 'if', not using conditional expressions; otherwise GDB
8407 complains about the types in the unevaluated arm when the argument
8408 is an integer literal.
8409 (xgetint): Simplify expression.
8410 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8411 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8412 Zaretskii in <http://bugs.gnu.org/12036#13>.
8413 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8414 needed now that we have gdb_make_enums_visible.
8415 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8416 (enum enum_USE_LSB_TAG):
8417 New enum types, packaging up enums that need to be exported to GDB.

8435 * xdisp.c (syms_of_xdisp): Likewise.
8436 * xfns.c (syms_of_xfns): Likewise.
8438 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8440 Fast save_excursion_save and save_excursion_restore.
8441 * lisp.h (struct Lisp_Excursion): New data type.
8442 (PVEC_EXCURSION): New pseudovector type.
8443 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8444 to deal with it. Adjust comments.

8458 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8459 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8460 emacs.c, as this is a more-suitable home. Had this been done earlier
8461 the fix for 12036 would have avoided some of the problems noted in
8462 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8463 would have been more obvious.
8464 * emacs.c: Do not include <verify.h>; no longer needed.
8465 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8466 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8467 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8468 Remove; now done in lisp.h.

8473 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8474 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8475 not be usable in #if. This simplifies things.
8477 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8479 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8481 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8483 Simplify export of symbols to GDB (Bug#12036).
8484 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8485 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8486 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8487 Adjust to changes in lisp.h and emacs.c, by using
8488 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8489 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8490 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8491 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8492 instead of gdb_valbits.
8493 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8494 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8495 instead of gdb_array_mark_flag.
8496 (xboolvector): Get size from $->size, not $->header.size.
8497 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8498 (xreload, hook-run, hookpost-run): Remove.
8499 * emacs.c: Include <verify.h>.
8500 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8501 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8503 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8504 (gdb_USE_LSB_TAG): New enum constants.
8505 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8506 Also define these as enum constants, so they're visible to GDB.
8507 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8508 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8509 as constants, so they're visible to GDB.
8510 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8511 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8512 Now enum constants, not macros, so they're visible to GDB.
8513 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8514 more convenient now. All uses changed.
8515 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8516 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8518 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8521 * editfns.c (save_restriction_restore): Free restriction data.
8523 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8525 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8526 add argument, tune behavior, and adjust all callers.
8528 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8530 Use typedef for EMACS_INT, EMACS_UINT.
8531 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8532 than macros. This simplifies debugging in the usual case, since
8533 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8534 and it allows expressions involving EMACS_INT casts.
8535 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8537 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8539 * nsterm.m (ns_read_socket): Return early if there is a modal
8542 2012-07-25 Martin Rudalics <rudalics@gmx.at>

8545 that FOCUS-FRAME can be omitted.
8547 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8549 Adjust buffer text indirection counters at the end of Fkill_buffer.
8550 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8551 buffer is definitely dead. This should really fix an issue reported
8552 by Christoph Scholtes again. (Bug#12007).
8553 (init_buffer_once): Initialize indirection counters of
8554 buffer_defaults and buffer_local_symbols (for sanity and safety).
8556 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8558 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8559 and continuation glyphs on tooltip frames, leave them at zero.
8560 Avoids continued lines in tooltips. (Bug#11832)
8562 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8564 Simplify copy_overlay.
8565 * buffer.c (copy_overlay): Simplify. Use build_marker.

9399 * nsterm.m (ns_term_init):
9400 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9401 * nsterm.m (ns_term_init):
9402 Avoid the need for strncpy, by using build_string or
9403 make_unibyte_string directly. Use dtoastr, not snprintf.
9404 * process.c (Fmake_network_process): Diagnose service names that
9405 are too long, rather than silently truncating them or creating

9475 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9476 We include usg5-4-common.h, which defines them both.
9478 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9479 O_RDONLY already includes it).
9481 Stop ns builds setting the EMACSLOADPATH environment variable.
9482 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9483 Now it does not set EMACSLOADPATH, just returns the load-path string.
9484 * nsterm.h: Update accordingly.
9485 * lread.c [HAVE_NS]: Include nsterm.h.
9486 (init_lread) [HAVE_NS]: Use ns_load_path.
9487 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9489 2012-07-09 Glenn Morris <rgm@gnu.org>
9491 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9492 since the included bsd-common.h does so.
9494 Stop ns builds setting the EMACSPATH environment variable.
9495 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9496 (ns_init_paths): Do not set EMACSPATH.
9497 * nsterm.h (ns_exec_path): Add it.
9498 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9501 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9503 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9505 * process.c (wait_reading_process_output): 'waitchannels' was unset
9506 when read_kbd || !NILP (wait_for_cell); fix this.
9508 Add GCC-style 'const' attribute to functions that can use it.
9509 * character.h (char_resolve_modifier_mask):
9510 * keyboard.h (make_ctrl_char):
9511 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9512 (init_character_once, next_almost_prime, init_fns, init_image)
9513 (flush_pending_output, init_sound):
9514 * mem-limits.h (start_of_data):
9515 * menu.h (finish_menu_items):

9518 Declare the dummy function with ATTRIBUTE_CONST.
9519 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9520 Add decls with ATTRIBUTE_CONST.
9522 Minor improvements to make_formatted_string.
9523 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9524 where int is good enough, as vsprintf returns an int.
9525 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9527 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9529 Use make_formatted_string to avoid double length calculation.
9530 * lisp.h (make_formatted_string): New prototype.
9531 * alloc.c (make_formatted_string): New function.
9532 * buffer.c (Fgenerate_new_buffer_name): Use it.
9533 * dbusbind.c (syms_of_dbusbind): Likewise.
9534 * editfns.c (Fcurrent_time_zone): Likewise.
9535 * filelock.c (get_boot_time): Likewise.
9536 * frame.c (make_terminal_frame, set_term_frame_name)
9537 (x_report_frame_params): Likewise.
9538 * image.c (gs_load): Likewise.
9539 * minibuf.c (get_minibuffer): Likewise.

9549 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
9550 * nsterm.h (ns_etc_directory): Add it.
9551 * callproc.c [HAVE_NS]: Include nsterm.h.
9552 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
9554 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9556 Move marker debugging code under MARKER_DEBUG.
9557 * marker.c (MARKER_DEBUG): Move marker debugging code under
9558 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9559 for bootstrap with --enable-checking (~3x slowdown reported
9560 by Juanma Barranquero <lekktu@gmail.com>).
9561 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9563 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9565 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9566 See <http://bugs.gnu.org/11825#29>.
9568 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9570 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9571 has no font, use the frame's font. (Bug#11813)
9572 (display_line): Add commentary about displaying truncation glyphs
9574 (produce_special_glyphs): Move here from term.c.
9576 * term.c (produce_special_glyphs): Move to xdisp.c.
9578 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9581 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9583 * xdisp.c (display_line): Avoid warning about implicit declaration
9586 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9588 * lisp.h: Remove empty conditional.
9590 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9592 * lread.c (load_path_check): Now static.
9594 Fix some minor --with-ns problems found by static checking.
9595 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9596 (x_set_font) [!HAVE_X_WINDOWS]:
9597 * image.c (xpm_load_image) [HAVE_NS]:
9598 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9599 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9600 Remove unused local.
9601 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9602 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9603 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9604 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9605 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9606 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9607 Fix pointer signedness problem.
9608 * xfaces.c (FRAME_X_FONT_TABLE):
9609 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9611 2012-07-07 Glenn Morris <rgm@gnu.org>
9613 * lread.c (load_path_check): New function, split from init_lread.
9614 (init_lread): Reorganize. Motivation:
9615 If EMACSLOADPATH is set, check/warn about that rather than the
9616 defaults, which we are not going to use. Hence we can remove
9617 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9618 Don't warn if site-lisp directories are missing.
9619 If not installed, start from a blank load-path, since
9620 PATH_LOADSEARCH refers to the eventual installation directories.
9622 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9624 Support truncation and continuation glyphs on GUI frames, when
9625 fringes are disabled. (Bug#11832)
9626 * xdisp.c (init_iterator): Get dimensions of truncation and
9627 continuation glyphs even if on GUI frames.
9628 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9629 or both, are absent.
9630 (start_display, move_it_in_display_line_to): Handle the case of a
9631 GUI frame without a fringe to display continuation or truncation
9633 (insert_left_trunc_glyphs): Support GUI frames: make sure
9634 truncation glyphs overwrite enough glyphs from the current line to
9635 have sufficient space in pixels.
9636 (display_line): Support truncation and continuation glyphs on GUI
9637 frames. If some spare pixels are left on the line after inserting
9638 the truncation glyphs, fill that space with a stretch glyph of a
9639 suitably computed width.
9641 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9642 produce_glyphs, to support GUI sessions.
9644 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9646 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9648 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9650 Do not require float-time's arg to fit in time_t (Bug#11825).
9651 This works better on hosts where time_t is unsigned, and where
9652 float-time is applied to the (negative) difference between two times.
9653 * editfns.c (decode_time_components): Last arg is now double *,
9654 not int *, and means to store all the result as a double, without
9655 worrying about whether the seconds part fits in time_t.
9656 All callers changed.
9657 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9658 All callers changed.
9659 (Ffloat_time): Do not fail merely because the specified time falls
9660 outside of time_t range.
9662 2012-07-07 Glenn Morris <rgm@gnu.org>
9664 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9668 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9670 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9671 Update dependencies.
9673 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9675 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9677 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

9679 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9680 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9681 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9682 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9684 * xfont.c (compare_font_names): Redo to omit the need for casts.
9686 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9688 * xfns.c (Fx_change_window_property): Doc fix.
9689 * w32fns.c (Fx_change_window_property): Doc fix.
9691 * w32fns.c (Fx_window_property): Accept the same arguments as the
9692 X Windows version. Doc fix.
9693 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9695 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9696 Eli Zaretskii <eliz@gnu.org>
9698 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9699 Windows-specific code from nt/config.nt moved here.
9700 Obsolete settings removed.
9702 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9704 * process.c: Avoid unnecessary calls to gettime.
9705 (wait_reading_process_output): Don't get the time of day
9706 when gobbling data immediately and not waiting, as there's no need
9707 for it in that case. This removes a FIXME.
9709 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9711 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9712 is defined (Bug#11768).
9714 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9716 Fix marker debugging code.
9717 * marker.c (byte_char_debug_check): Do not perform the check
9718 if buffer is not multibyte.
9719 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9720 Call byte_char_debug_check with correct arguments.
9722 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9724 Compile marker debugging code only if ENABLE_CHECKING is defined.
9725 * marker.c (byte_char_debug_check, count_markers):
9726 Use only if ENABLE_CHECKING is defined.
9727 (byte_debug_flag): Remove.
9728 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9729 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9731 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9733 Avoid code repetition in marker-related functions.
9734 * marker.c (attach_marker): New function.
9735 (Fset_marker, set_marker_restricted, set_marker_both)
9736 (set_marker_restricted_both): Use it.
9737 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9738 Consistently rename charno to charpos.
9739 (marker_position): Add eassert.
9740 (marker_byte_position): Convert to eassert.

9752 * lisp.h (build_marker): New prototype.
9753 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9754 * composite.c (autocmp_chars): Likewise.
9755 * editfns.c (buildmark): Remove.
9756 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9757 (save_restriction_save): Use build_marker.
9758 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9759 * window.c (save_window_save): Likewise.
9761 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9763 Do not use Fdelete_overlay in delete_all_overlays
9764 to avoid redundant calls to unchain_overlay.
9765 * buffer.c (drop_overlay): New function.
9766 (delete_all_overlays, Fdelete_overlay): Use it.
9767 * minibuf.c (get_minibuffer): Fix comment.
9769 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9771 Port to OpenBSD 5.1 amd64.
9772 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9773 This is needed for OpenBSD, and should be harmless on all BSD systems.
9774 Also, include <sys/sysctl.h>, as it should be available on all
9775 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9776 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9777 use p_pid member, not kp_proc.pid.
9779 2012-07-06 Glenn Morris <rgm@gnu.org>
9781 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9783 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9785 More xmalloc and related cleanup.
9786 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9787 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

9792 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9793 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9794 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9796 Omit needless casts involving void * pointers and allocation.
9797 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9798 as the former is more robust if P's type is changed.
9799 Prefer xzalloc to xmalloc + memset 0.
9800 Simplify malloc-or-realloc to realloc.
9801 Don't worry about xmalloc returning a null pointer.
9802 Prefer xstrdup to xmalloc + strcpy.
9803 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9805 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9806 alloca of a constant.
9808 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9810 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9811 hscroll is larger than the line width. Fixes long and futile
9812 looping inside extend_face_to_end_of_line (on a TTY) producing
9813 glyphs that are not needed and thrown away.
9815 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9817 * marker.c (set_marker_restricted_both): Simplify by using

9831 followed by gtk_box_set_homogeneous (Bug#11768).
9832 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9833 (update_theme_scrollbar_width, xg_create_scroll_bar):
9834 Use gtk_scrollbar_new (Bug#11768).
9835 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9836 (is_box_type): New function (Bug#11768).
9837 (xg_tool_item_stale_p): Call is_box_type.
9838 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9839 with default display (Bug#11768).
9841 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9843 * xdisp.c (window_hscroll_limited): New function.
9844 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9845 coordinates when window's hscroll is set to insanely large
9848 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9850 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9851 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9853 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9856 * lisp.h (xzalloc): New prototype. Omit needless casts.
9857 * alloc.c (xzalloc): New function. Omit needless casts.

9912 Problem reported by Troels Nielsen in
9913 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9915 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9917 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9918 This should be fixed in a better way; see Eli Zaretskii in
9919 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9920 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9922 * fileio.c (time_error_value): Rename from special_mtime.
9923 The old name's problems were noted by Eli Zaretskii in
9924 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9926 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9927 This variable's comment says Emacs needs at least one GDB-visible
9928 symbol of type enum pvec_type, to work around GDB problems.
9929 The symbol's value doesn't matter.
9931 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9932 that causes compilation to fail on pre-C99 compilers.
9934 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9936 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9937 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9939 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9941 * buffer.c (init_buffer_once): Fix initialization of
9942 headers for buffer_defaults and buffer_local_symbols.
9943 Reported by Juanma Barranquero <lekktu@gmail.com>.
9945 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9947 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9948 * lisp.h (enum pvec_type): Use fewer bits.
9949 (PSEUDOVECTOR_SIZE_BITS): New constant.
9950 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9951 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9952 change in pvec_type.
9953 (PSEUDOVECTOR_TYPEP): New macro.
9954 (TYPED_PSEUDOVECTORP): Use it.
9955 * fns.c (internal_equal): Adapt code to extract pvectype.
9956 * emacs.c (gdb_pvec_type): Update type.
9957 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9958 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9959 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9960 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9961 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9962 abusing vector->header.next.nbytes.
9963 (live_vector_p): Use PVEC_TYPE.
9964 (mark_object): Adapt code to extract pvectype. Use switch.
9966 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9968 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9969 Tighten new eassert a bit.
9971 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9973 Fix compilation with --enable-gcc-warnings and -O1
9975 * doprnt.c (doprnt): Change type of tem to int, initialize
9976 to avoid compiler warning. Add eassert.
9977 * search.c (simple_search): Initialize match_byte to avoid
9978 compiler warning. Add eassert.
9980 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9982 Avoid weird behavior with large horizontal scrolls.
9983 Without this change, for example, large hscroll values would
9984 mess up Emacs's display on Fedora 15 x86, presumably due to
9985 overflows in int calculations in the display code.
9986 Also, if buffers had long lines, Emacs would freeze.
9987 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9988 (set_window_hscroll): New function, containing the old guts of
9989 Fset_window_hscroll. Return the clipped value.
9990 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9991 This avoids the need to check against PTRDIFF_MAX.
9993 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9995 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9997 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9999 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10001 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10002 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10003 since GCC 4.4.6 issues a bogus warning for them.
10005 Fix bugs in file timestamp newness comparisons.
10006 * fileio.c (Ffile_newer_than_file_p):
10007 * lread.c (Fload): Use full timestamp resolution of files,
10008 not just the 1-second resolution, so that files that are only
10009 slightly newer still count as newer.
10010 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10011 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10013 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10015 * fileio.c: Improve handling of file time marker. (Bug#11852)
10016 (special_mtime): New function.
10017 (Finsert_file_contents, Fverify_visited_file_modtime):
10018 Use it to set special mtime values consistently.
10020 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10022 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10023 marker for non-existing file. (Bug#11852)
10025 2012-07-03 Glenn Morris <rgm@gnu.org>
10027 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10028 and did not make it into globals.h).
10030 2012-07-03 Tom Tromey <tromey@redhat.com>
10032 * window.c (Fset_window_margins, Fset_window_fringes)
10033 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10034 * textprop.c (Fprevious_property_change): No longer static.
10035 * syntax.c (Fsyntax_table_p): No longer static.
10036 * process.c (Fget_process, Fprocess_datagram_address): No longer
10038 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
10039 * keyboard.c (Fcommand_execute): No longer static.
10041 * insdel.c (Fcombine_after_change_execute): No longer static.

10056 * dispextern.h: Remove EXFUNs.
10057 * intervals.h: Remove EXFUNs.
10058 * fontset.h: Remove EXFUN.
10059 * font.h: Remove EXFUNs.
10060 * dosfns.c (system_process_attributes): Remove EXFUN.
10061 * keymap.h: Remove EXFUNs.
10062 * lisp.h: Remove EXFUNs.
10063 * w32term.h: Remove EXFUNs.
10064 * window.h: Remove EXFUNs.
10065 * xsettings.h: Remove EXFUN.
10066 * xterm.h: Remove EXFUN.
10068 2012-07-03 Glenn Morris <rgm@gnu.org>
10070 * lisp.h (Frandom): Make it visible to C.
10071 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10072 buffer for invisible buffers. (Bug#1229)
10074 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10076 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10077 values which aren't power of 2.
10078 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10079 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10082 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10084 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10086 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10088 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10090 * alloc.c (allocate_vector_block): Remove redundant
10091 calls to mallopt if DOUG_LEA_MALLOC is defined.
10092 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10093 avoid calls to mallopt if zero_vector is returned.
10095 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10097 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10098 is enabled, avoid dereferencing NULL current_sblock if
10101 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10103 Cleanup basic buffer management.
10104 * buffer.h (struct buffer): Change layout to use generic vector
10105 marking code. Fix some comments. Change type of 'clip_changed'
10106 to bitfield. Remove unused #ifndef old.
10107 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10108 (GET_OVERLAYS_AT): Fix indentation.
10109 (for_each_per_buffer_object_at): New macro.
10110 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10111 (Fbuffer_local_variables): Use it.
10112 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10113 * alloc.c (allocate_buffer): Adjust to match new layout of
10114 struct buffer. Fix comment.
10115 (mark_overlay): New function.
10116 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10117 Lisp area of struct buffer.
10118 (mark_object): Use it. Adjust marking of misc objects
10119 and related comments.
10121 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10123 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10124 wrapper that is not needed because the wrapped code is a no-op (zero
10125 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10126 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10128 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10130 * alloc.c (mark_buffer): Simplify. Remove prototype.
10131 (mark_object): Add comment. Reorganize marking of vector-like
10132 objects. Use CHECK_LIVE for all vector-like objects except buffers
10133 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10134 Avoid redundant calls to mark_vectorlike for bool vectors.
10136 2012-06-30 Glenn Morris <rgm@gnu.org>
10138 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10140 * epaths.in (PATH_SITELOADSEARCH): New.
10141 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10142 This is rather than relying on --enable-locallisppath elements
10143 having "site-lisp" in their names. (Bug#10208#25, 11658)
10145 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10147 * w32proc.c (sys_select): Accept and ignore one more argument.
10149 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10151 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10152 (pselect) [!MS_DOS]: Redirect to sys_select.
10154 * sysdep.c: Don't include dos.h and dosfns.h.
10156 * process.c (sys_select):
10157 * msdos.c (sys_select): Accept one more argument and ignore it.
10159 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10160 adapt data types and code to that.
10163 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10164 which clashes with the gnulib function of the same name.
10166 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10168 * font.c (font_style_to_value, font_style_symbolic)
10169 (font_prop_validate_style): Add type checks for values in
10172 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10174 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10177 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10179 * xdisp.c (try_window_id): Undo last change.
10181 * w32.c (getwd): Adjust commentary about startup_dir.
10182 (init_environment): Always call sys_access, even in non-MSVC
10183 builds. Don't chdir to the directory of the Emacs executable.
10184 This undoes code from 1997 which was justified by the need to
10185 "avoid conflicts when removing and renaming directories". But its
10186 downside was that every relative file name was being interpreted
10187 relative to the directory of the Emacs executable, which can never
10188 be TRT. In particular, it broke sys_access when called with
10189 relative file names.
10190 (sys_access): Map GetLastError to errno.
10192 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10194 * window.h (struct window): Change type of 'fringes_outside_margins'
10195 to bitfield. Fix comment. Adjust users accordingly.
10196 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10198 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10201 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10203 * gnutls.c (emacs_gnutls_handshake):
10204 Add QUIT to make the loop interruptible.
10206 2012-06-29 Glenn Morris <rgm@gnu.org>
10208 * charset.c (init_charset): Make lack of etc/charsets fatal.
10210 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10212 * editfns.c (region_limit): Fix type mismatch.
10214 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10216 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10217 undefined. Convert from xassert to eassert.
10218 * nsmenu.m: Convert from xassert to eassert.
10219 * nsterm.m: Likewise.
10221 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10223 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10225 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10227 Avoid integer overflow on scroll-left and scroll-right.
10228 * window.c (HSCROLL_MAX): New macro.
10229 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10230 overflow when requested scroll falls outside ptrdiff_t range.
10232 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10234 * window.h (struct window): Change type of 'hscroll',
10235 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10236 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10237 Adjust users accordingly.
10238 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10239 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10240 from EMACS_INT to ptrdiff_t.
10241 (make_window): Omit redundant initialization.
10243 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
10245 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
10247 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10249 * window.h (struct window): Change type of 'use_time' and
10250 'sequence_number' from Lisp_Object to int.

10259 enabled with --enable-checking=[all,glyphs] configure option.
10260 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10261 adjust comments accordingly.

10263 undefined, adjust comments accordingly.

10310 * alloc.c (allocate_string_data): Remove dead code.
10311 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
10312 avoid GCC warning about unused macro.
10314 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10316 * alloc.c (allocate_string): Omit intervals initialization.
10317 * alloc.c (make_uninit_multibyte_string): Initialize intervals

10342 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10343 when building with Clang.

10374 * alloc.c: Remove build_string.

10382 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10384 Use sprintf return value instead of invoking strlen on result.
10385 In the old days this wasn't portable, since some sprintf
10386 implementations returned char *. But they died out years ago and
10387 Emacs already assumes sprintf returns int.
10388 Similarly for float_to_string.
10389 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10390 * ccl.c (ccl_driver):

10394 * print.c (print_object):
10395 * xdisp.c (message_dolog):
10396 * xfns.c (syms_of_xfns):
10397 Use sprintf or float_to_string result to avoid need to call strlen.
10398 * data.c (Fnumber_to_string):
10399 Use make_unibyte_string, since the string must be ASCII.
10400 * lisp.h, print.c (float_to_string): Now returns int length.
10401 * term.c (produce_glyphless_glyph):
10402 Use sprintf result rather than recomputing it.
10404 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10405 * Makefile.in (ALL_CFLAGS):
10406 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10442 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10443 instead of truncating it to 63 (admittedly a generous limit).
10445 * process.c: Fix spelling and caps in comments.
10447 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

10498 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10500 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10501 * lisp.h (WAIT_READING_MAX): New macro.
10502 * dispnew.c (Fsleep_for, sit_for):
10503 * keyboard.c (kbd_buffer_get_event):
10504 * process.c (Faccept_process_output):
10505 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10506 This improves on the previous patch, which introduced a bug
10507 when time_t is unsigned and as wide as intmax_t.
10508 See <http://bugs.gnu.org/9000#51>.
10510 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10539 language ID in the event parameters.
10541 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10542 event.code, not the obscure "character set ID".
10544 2012-06-23 Chong Yidong <cyd@gnu.org>
10546 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10573 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10575 Support higher-resolution time stamps (Bug#9000).
10576 The time stamps are only nanosecond-resolution at the C level,
10577 since that's the best that any real-world system supports now.
10578 But they are picosecond-resolution at the Lisp level, as that's
10579 easy, and leaves room for future OS improvements.
10581 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10584 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10585 Don't get current time unless it's needed.
10587 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10588 now provides it if it's absent.
10589 (start_atimer): Port to higher-res time stamps.
10590 Check for time stamp overflow. Don't get current time more
10591 often than is needed.
10593 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10594 Include systime.h, not time.h.
10595 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10597 * dired.c: Include stat-time.h.
10598 (Ffile-attributes): File times now have higher resolution.
10600 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10601 (struct image): Timestamp now has higher resolution.
10603 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10604 has at least microseconds now. All uses removed.
10605 (update_frame, update_single_window, update_window, update_frame_1)
10606 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10607 (duration_to_sec_usec): Remove; no longer needed.
10609 * editfns.c (time_overflow): Now extern.
10610 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10611 (float-time, Fformat_time_string, Fcurrent_time_string)

10615 (decode_time_components, lisp_seconds_argument): New functions.
10616 (make_time): Now static.
10617 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10618 Report an error if the time is invalid, rather than having the caller
10621 * fileio.c: Include <stat-time.h>
10622 (Fcopy_file): Copy higher-resolution time stamps.
10623 Prefer to set the time stamp via a file descriptor if that works.
10624 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10625 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10626 (Fvisited_file_modtime, Fset_visited_file_modtime):
10627 Support higher-resolution time stamps.
10629 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10631 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10633 * image.c (prepare_image_for_display, clear_image_cache)
10634 (lookup_image): Port to higer-resolution time stamps.
10636 * keyboard.c (start_polling, bind_polling_period):
10637 Check for time stamp overflow.
10638 (read_char, kbd_buffer_get_event, timer_start_idle)
10639 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10640 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10641 Port to higher-resolution time stamps. Do not assume time_t is signed.
10642 (decode_timer): New function. Timers are now vectors of length 9,
10643 not 8, to accommodate the picosecond component.
10644 (timer_check_2): Use it.
10646 * nsterm.m (select_timeout, timeval_subtract): Remove.
10647 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10648 as they're a bit more accurate and handle overflow better.
10649 (ns_select): Change prototype to be compatible with pselect.
10650 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10651 * nsterm.h (ns_select): Adjust prototype.
10653 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10654 us-resolution time stamps.
10655 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10657 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10659 * lisp.h (time_overflow): New decl.
10660 (wait_reading_process_output): First arg is now intmax_t, not int,
10661 to accommodate larger waits.
10663 * process.h (struct Lisp_Process.read_output_delay):
10664 Now counts nanoseconds, not microseconds.
10665 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10667 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10668 (wait_reading_process_output):
10669 Port to ns-resolution time stamps.
10670 (Faccept_process_output, wait_reading_process_output):
10671 Check for time stamp overflow. Do not assume time_t is signed.
10672 (select_wrapper): Remove; we now use pselect.
10673 (Fprocess_attributes): Now generates ns-resolution time stamps.
10675 * sysdep.c: Include utimens.h. Don't include utime.h
10676 or worry about struct utimbuf; gnulib does that for us now.
10677 (gettimeofday): Remove; gnulib provides a substitute.
10678 (make_timeval): New function.
10679 (set_file_times): Now sets ns-resolution time stamps.
10680 New arg FD; all uses changed.
10681 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10682 (system_process_attributes):
10683 Now returns ns-resolution time stamp. All uses changed.
10684 Check for time stamp overflow.
10686 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10687 provides a substitute now.
10689 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10690 since it guarantees struct timespec.
10691 (EMACS_TIME): Now struct timespec, so that we can support
10692 ns-resolution time stamps.
10693 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10694 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10695 (EMACS_USECS): Remove.
10696 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10697 so multiply the arg by 1000 before storing it.
10698 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10700 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10701 Port to ns-resolution time stamps.
10702 (EMACS_TIME_NEG_P): Remove; replaced by....
10703 (EMACS_TIME_SIGN): New macro.

10705 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10706 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10707 (make_timeval, make_lisp_time, decode_time_components): New decls.
10708 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10709 that it mishandled time_t overflow. You can't compare by subtracting!
10710 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10711 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10713 * term.c: Include <sys/time.h>.
10714 (timeval_to_Time): New function, for proper overflow wraparound.
10715 (term_mouse_position, term_mouse_click): Use it.
10717 * undo.c (record_first_change): Support higher-resolution time stamps
10718 in the undo buffer.
10719 (Fprimitive_undo): Use them when restoring time stamps.
10721 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10722 (w32_get_internal_run_time):
10723 Port to higher-resolution Emacs time stamps.
10724 (ltime): Now accepts single 64-bit integer, as that's more convenient
10727 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10729 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10730 for compatibility with pselect. Support ns-resolution time stamps.
10732 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10734 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10735 Check for time stamp overflow, and support ns-resolution time stamps.
10737 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10738 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10739 (timeval_subtract): Remove; no longer needed.
10740 (XTflash, XTring_bell, x_wait_for_event):
10741 Port to ns-resolution time stamps. Don't assume time_t is signed.
10743 2012-06-22 Chong Yidong <cyd@gnu.org>

10747 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10749 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10750 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10751 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10752 staticidx goes up to 1597 out of 1600 = 0x640.)
10754 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10756 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10757 Otherwise, the umask might be mistakenly 0 while handling input signals.
10759 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10761 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10767 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10768 access to `contents' member of Lisp_Vector objects with AREF and ASET
10771 2012-06-19 Chong Yidong <cyd@gnu.org>
10773 * frame.c (delete_frame): When selecting a frame on a different
10774 text terminal, do not alter the terminal's top-frame.
10776 * xdisp.c (format_mode_line_unwind_data): Record the target
10777 frame's selected window and its terminal's top-frame.
10778 (unwind_format_mode_line): Restore them.
10779 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10781 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10782 since tty frames can be explicitly named.
10783 (prepare_menu_bars): Likewise.
10785 * term.c (Ftty_top_frame): New function.
10787 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10790 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10791 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10792 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10793 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10794 (METER_1, METER_2): Simplify.
10796 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10798 * data.c (Fdefalias): Return `symbol' (bug#11686).
10800 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10802 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10803 gets killed during executing of this function (Bug#11665).
10804 Try to always return Qt when the buffer has been actually killed.
10805 (Vkill_buffer_query_functions): In doc-string say that functions
10806 run by this hook should not change the current buffer.
10808 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10810 Fix recently-introduced process.c problems found by static checking.
10811 * process.c (write_queue_push, write_queue_pop, send_process):
10812 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
10813 (write_queue_pop): Fix pointer signedness problem.
10814 (send_process): Remove unused local.
10816 2012-06-17 Chong Yidong <cyd@gnu.org>
10818 * xdisp.c (redisplay_internal): No need to redisplay terminal
10819 frames that are not on top.

10828 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10830 * lisp.h (eassert): Assume C89 or later.
10831 This removes the need for CHECK.
10832 (CHECK): Remove. Its comments about always evaluating its
10833 argument were confusing, as 'eassert' typically does not evaluate
10836 * coding.c (produce_chars): Use ptrdiff_t, not int.
10838 * xterm.c (x_draw_underwave): Check for integer overflow.
10839 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
10841 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
10843 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
10844 referenced (Bug#11583).
10846 2012-06-16 Aurelien Aptel <aurelien.aptel@gmail.com>

11173 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11174 would mishandle a string argument "Xc" if X was a multibyte

11229 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11230 Convert pctcpu and pctmem to Lisp float properly.

11247 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11248 change its type from Lisp_Object to bitfield.

11257 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11258 Use 'float' consistently, rather than 'float' in most places
11259 and 'double' in a couple of places.
11261 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11263 * xdisp.c (handle_stop): Detect whether we have overlay strings
11264 loaded by testing it->current.overlay_string_index to be
11265 non-negative, instead of checking whether n_overlay_strings is
11266 positive. (Bug#11587)

11276 * search.c (search_buffer): Remove calls to

11283 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11284 for the duration of call to load_charset, to avoid problems with

11295 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

11306 The following changes affect the code only when profiling.
11307 * dispnew.c (__executable_start): Rename from safe_bcopy.
11308 Define only on platforms that need it.
11309 * emacs.c: Include <sys/gmon.h> when profiling.
11310 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11311 (__executable_start): Remove decl, since lisp.h does it now.
11312 (safe_bcopy): Remove decl; no longer has that name.
11313 (main): Coalesce #if into single bit of code, for simplicity.
11314 Cast pointers to uintptr_t, since standard libraries want integers
11316 * lisp.h (__executable_start): New decl.
11318 2012-05-31 Glenn Morris <rgm@gnu.org>
11320 * image.c (Fimagemagick_types): Doc fix.
11322 2012-05-30 Jim Meyering <meyering@redhat.com>
11324 * callproc.c (Fcall_process_region): Include directory component
11325 in mkstemp error message (Bug#11586).
11327 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11329 * alloc.c, lisp.h (make_pure_vector): Now static.
11331 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
11333 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
11334 Move to byte-run.el.
11335 (Fautoload): Do the hash-doc more carefully.
11336 * data.c (Fdefalias): Purify definition, except for keymaps.
11337 (Qdefun): Move from eval.c.
11338 * lisp.h (Qdefun): Remove.
11339 * lread.c (read1): Tiny simplification.
11341 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11343 Do not create empty overlays with the evaporate property (Bug#9642).
11344 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11345 Bug#9642, but explicitly check that the buffer the overlay would
11346 be moved to is live and rearrange lines to make sure that errors
11347 will not put the overlay in an inconsistent state.
11348 (Fdelete_overlay): Cosmetics.
11350 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11352 * w32term.c (my_bring_window_to_top): New function.
11353 (x_raise_frame): Use handle returned by DeferWindowPos, which
11354 could be different from the original one.
11355 Call my_bring_window_to_top instead of my_set_foreground_window.
11358 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11359 by calling BringWindowToTop.
11361 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

11364 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11366 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11367 This avoids undefined behavior that might cause the eassert
11368 to not catch an out-of-range value.
11370 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11372 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11373 Update dependencies.
11375 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11377 * bidi.c (bidi_mirror_char): Fix last change.
11379 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11382 when referring to sectname field in printf format.
11384 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11386 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11387 Only r_alloc_inhibit_buffer_relocation needed to be added;
11388 the others were already declared.
11390 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11391 before checking whether it's out of range. Put the check inside
11393 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11395 2012-05-27 Ken Brown <kbrown@cornell.edu>
11397 * callproc.c (Fcall_process): Restore a line that was accidentally
11398 commented out in the 2011-02-13 change (bug#11547).
11400 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11402 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11403 defined on ralloc.c.
11405 * buffer.c [REL_ALLOC]: Remove prototypes of
11406 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11407 they are now on lisp.h.
11409 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11411 * search.c (search_buffer): Use it to inhibit relocation of buffer
11412 text while re_search_2 is doing its job, because re_search_2 is
11413 passed C pointers to buffer text. (Bug#11519)
11415 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11416 Update value to 24.
11418 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11419 state after an additional call to move_it_in_display_line_to, keep
11420 the values of it->max_ascent and it->max_descent found for the
11422 (pos_visible_p): Revert the comparison against bottom_y to what it
11423 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11426 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11428 Fix coding-related core dumps with gcc -ftrapv.
11429 The code was computing A - B, where A and B are pointers, and B is
11430 random garbage. This can lead to core dumps on platforms that
11431 have special pointer registers, and it also leads to core dumps on
11432 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11433 A - B only when B is initialized properly.
11434 * coding.c (coding_set_source, coding_set_destination): Return void.
11435 (coding_change_source, coding_change_destinations): New functions,
11436 with the old behaviors of coding_set_source and coding_set_destination.
11437 All callers that need an offset changed to use these new functions.
11439 2012-05-26 Glenn Morris <rgm@gnu.org>
11441 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11443 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11445 Extend mouse support on W32 text-mode console.
11446 * xdisp.c (draw_row_with_mouse_face):
11447 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11449 * w32console.c: Include window.h.
11450 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11452 (initialize_w32_display): Initialize mouse-highlight data.
11454 * w32inevt.c: Include termchar.h and window.h.
11455 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11456 moves, call note_mouse_highlight. If help_echo changed, call
11457 gen_help_event to produce help-echo message in the echo area.
11458 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11461 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11463 * lread.c (read1): Simplify slightly to avoid an overflow warning
11464 with GCC 4.7.0 on x86-64.
11466 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11468 * bidi.c (bidi_mirror_char): Revert last change: an int is
11469 definitely wide enough here.
11471 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11473 Fix integer width and related bugs (Bug#9874).
11474 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11475 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11476 (string_bytes, check_sblock, allocate_string_data):
11477 (compact_small_strings, Fmake_bool_vector, make_string)
11478 (make_unibyte_string, make_multibyte_string)

11480 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11481 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11483 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11484 (allocate_pseudovector):
11485 Use int, not EMACS_INT, where int is wide enough.
11486 (inhibit_garbage_collection, Fgarbage_collect):
11487 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11488 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11489 int might not be wide enough.
11490 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11491 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11492 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11493 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11494 (bidi_level_of_next_char, bidi_move_to_visually_next):
11495 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11496 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11497 (Fkill_buffer, Fset_buffer_major_mode)
11498 (advance_to_char_boundary, Fbuffer_swap_text)

11500 (overlay_touches_p, struct sortvec, record_overlay_string)
11501 (overlay_strings, recenter_overlay_lists)
11502 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11503 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11504 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11505 (Foverlay_recenter, last_overlay_modification_hooks_used)
11506 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11507 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11508 (validate_region): Omit unnecessary test for b <= e,
11509 since that's guaranteed by the previous test.
11510 (adjust_overlays_for_delete): Avoid pos + length overflow.
11511 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11512 (report_overlay_modification):
11513 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11514 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11515 Omit pointer cast, which isn't needed anyway, and doesn't work
11516 after the EMACS_INT -> ptrdiff_t change.
11517 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11518 * buffer.h: Adjust decls to match defn changes elsewhere.
11519 (struct buffer_text, struct buffer):
11520 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11521 Use EMACS_INT, not int, where int might not be wide enough.
11522 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11523 not int, to avoid needless 32-bit limit on 64-bit hosts.
11524 (exec_byte_code): Use tighter memory-full test, one that checks
11525 for alloca overflow. Don't compute the address of the object just
11526 before an array, as that's not portable. Use EMACS_INT, not
11527 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11528 * callint.c (Fcall_interactively):
11529 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11530 * callproc.c (call_process_kill, Fcall_process):
11531 Don't assume pid_t fits into an Emacs fixnum.
11532 (call_process_cleanup, Fcall_process, child_setup):
11533 Don't assume pid_t fits into int.
11534 (call_process_cleanup, Fcall_process, delete_temp_file)

11536 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11537 (Fcall_process): Simplify handling of volatile integers.
11538 Use int, not EMACS_INT, where int will do.
11539 * casefiddle.c (casify_object, casify_region, operate_on_word)
11540 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11541 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11542 (casify_object): Avoid integer overflow when overallocating buffer.
11543 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11544 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11545 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11546 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11547 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11548 integers are now checked earlier. All uses replaced with XINT.
11550 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11551 For CCL_MapSingle, check that content and value are in int range.
11552 (ccl_driver, Fregister_code_conversion_map):
11553 Check that Vcode_version_map_vector is a vector.
11554 (resolve_symbol_ccl_program): Check that vector header is in range.
11555 Always copy the vector, so that we can check its contents reliably
11556 now rather than having to recheck each instruction as it's being
11557 executed. Check that vector words fit in 'int'.
11558 (ccl_get_compiled_code, Fregister_ccl_program)
11559 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11560 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11561 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11562 contents are in range.
11563 (Fccl_execute_on_string): Check that status is in range.
11564 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11565 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11566 Accept and return EMACS_INT, not int, because callers can pass values
11567 out of 'int' range.
11568 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11569 (multibyte_chars_in_text, parse_str_as_multibyte)

11571 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11572 (string_escape_byte8, Fget_byte):
11573 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11574 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11575 avoid mishandling large integers.
11576 * character.h: Adjust decls to match defn changes elsewhere.
11577 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11578 (Ffind_charset_region):
11579 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11580 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11581 (load_charset_map_from_vector, Fdefine_charset_internal):
11582 Don't assume fixnum fits in int.
11583 (load_charset_map_from_vector, Fmap_charset_chars):
11584 Remove now-unnecessary CHECK_NATNUMs.
11585 (Fdefine_charset_internal): Check ranges here, more carefully.
11586 Don't rely on undefined behavior with signed left shift overflow.
11587 Don't assume unsigned int fits into fixnum, or that fixnum fits
11588 into unsigned int. Don't require max_code to be a valid fixnum;
11589 that's not true for gb10830 4-byte on a 32-bit host. Allow
11590 invalid_code to be a cons, for the same reason. Require code_offset
11591 to be a character. Avoid int overflow if max_char is close
11593 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11594 this is intended anyway and avoids some undefined behavior.
11595 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11596 INDEX_TO_CODE_POINT, as that's what it expects.
11597 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11598 * charset.h (DECODE_CHAR): Return int, not unsigned;
11599 this is what was intended anyway, and it avoids undefined behavior.
11600 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11601 integer-overflow issues.
11602 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11603 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11604 where the argument is EMACS_INT, and this behavior is not intended.
11605 * chartab.c (Fmake_char_table, Fset_char_table_range)
11606 (uniprop_get_decoder, uniprop_get_encoder):
11607 Don't assume fixnum fits in int.
11608 * cmds.c (move_point): New function, that does the gist of
11609 Fforward_char and Fbackward_char, but does so while checking
11610 for integer overflow more accurately.
11611 (Fforward_char, Fbackward_char): Use it.
11612 (Fforward_line, Fend_of_line, internal_self_insert)
11613 (internal_self_insert):
11614 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11615 Fix a FIXME, by checking for integer overflow when calculating
11616 target_clm and actual_clm.

11649 (consume_chars): Rewrite to not calculate an address outside buffer.
11650 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
11651 Don't access memory outside of the args array.
11652 (Fdefine_coding_system_internal): Check for charset-id overflow.
11653 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
11654 result of ENCODE_CHAR.
11655 * coding.h: Adjust decls to match defn changes elsewhere.
11656 (struct coding_system):
11657 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11671 (struct composition):
11672 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11673 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
11674 Do not attempt to compute the address of the object just before a
11675 buffer; this is not portable.
11677 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11678 (Faset): Use int, not EMACS_INT, where int is wide enough.
11679 (Fstring_to_number): Don't assume fixnums fit in int.

11687 (xd_signature, xd_append_arg, xd_retrieve_arg, Fdbus_message_internal)

12376 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12377 reference to image_cache->refcount.
12378 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12380 2012-05-17 Juri Linkov <juri@jurta.org>
12382 * search.c (Fword_search_regexp, Fword_search_backward)
12383 (Fword_search_forward, Fword_search_backward_lax)
12384 (Fword_search_forward_lax): Move functions to isearch.el
12385 (bug#10145, bug#11381).
12387 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12389 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12391 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12393 * lread.c (init_obarray): Declare Qt and Qnil as special.
12395 2012-05-14 Glenn Morris <rgm@gnu.org>
12397 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12398 Put "libexec" before "bin", for the sake of init_callproc_1.
12400 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12402 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12404 * unexaix.c: Port to more-recent AIX compilers.
12405 (report_error, report_error_1, make_hdr, copy_sym)
12406 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12407 Make arguments const char *, not char *, to avoid violations of C
12408 standard and to fix some AIX warnings reported by Gilles Pion.
12410 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12412 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12413 already have overlays loaded.
12414 (handle_single_display_spec): Before returning without displaying
12415 fringe bitmap, synchronize the bidi iterator with the main display
12416 iterator, by calling iterate_out_of_display_property.
12417 (iterate_out_of_display_property): Detect buffer iteration by
12418 testing that it->string is a Lisp string.
12419 (get_next_display_element): When the current object is exhausted,
12420 and there's something on it->stack, call set_iterator_to_next to
12421 proceed with what's on the stack, instead of returning zero.
12422 (set_iterator_to_next): If called at the end of a Lisp string,
12423 proceed to consider_string_end without incrementing string
12424 position. Don't increment display vector index past the end of
12425 the display vector. (Bug#11417)
12426 (pos_visible_p): Don't report a position visible when move_it_to
12427 stopped at the last line of window, which happens to be scanned
12428 backwards by the bidi iteration. (Bug#11464)
12430 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12432 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12433 and right-margin display specs even if the spec is invalid or we
12434 are on a TTY, and thus unable to display on the fringes.
12435 That's because the text with the property will not be displayed anyway,
12436 so we need to signal to the caller that this is a "replacing"
12437 display spec. This fixes display when the spec is invalid or we
12440 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12442 * unexaix.c (make_hdr): Fix typo in prototype.
12443 This bug broke the build on AIX. Problem reported by Gilles Pion.
12445 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12447 * keyboard.c (kbd_buffer_get_event): Read special events also in
12448 batch mode. (Bug#11415)
12450 2012-05-12 Glenn Morris <rgm@gnu.org>
12452 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12454 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12456 * lisp.mk (lisp): Add newcomment.elc.
12458 2012-05-12 Glenn Morris <rgm@gnu.org>
12460 * Makefile.in (MKDIR_P): New, set by configure.
12461 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12463 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12465 Remove unused function hourglass_started.
12466 * dispextern.h (hourglass_started):
12467 * w32fns.c (hourglass_started):
12468 * xdisp.c (hourglass_started): Remove.
12470 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12472 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12473 Update dependencies.
12475 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12477 * xgselect.c (xg_select): Put maxfds+1 into a var.
12478 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12480 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12482 2012-05-10 Dave Abrahams <dave@boostpro.com>
12484 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12485 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12487 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12489 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12490 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12491 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12492 Initialize xd_registered_buses.
12494 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12496 Untag more efficiently if USE_LSB_TAG.
12497 This is based on a proposal by YAMAMOTO Mitsuharu in
12498 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12499 For an admittedly artificial (nth 8000 longlist) benchmark on
12500 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12501 Emacs's overall text size by 1%.
12502 * lisp.h (XUNTAG): New macro.
12503 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12504 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12505 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12506 * eval.c (Fautoload):
12507 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12508 * frame.h (XFRAME): Use XUNTAG.
12510 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12511 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12512 Remove unportable assumptions about print widths of types like
12514 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12515 intptr_t when converting between pointer and integer, to avoid GCC
12516 warnings about wrong width.
12518 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12520 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12521 stack for each reader_thread, instead of defaulting to 8MB
12522 determined by the linker. This avoids failures in creating
12523 subprocesses on Windows 7, see the discussion in this thread:
12524 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12526 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12528 Fix up display of the *Minibuf-0* buffer in the mini window.
12529 * keyboard.c (read_char): Don't clear the echo area if there's no
12531 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12532 contents of *Minibuf-0*) if there's no message displayed in its stead.
12534 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12536 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12539 2012-05-06 Chong Yidong <cyd@gnu.org>
12541 * lisp.mk (lisp): Update.
12543 2012-05-05 Jim Meyering <meyering@redhat.com>
12545 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12547 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12549 * data.c (PUT_ERROR): New macro.
12550 (syms_of_data): Use it. Add new error type `user-error'.
12551 * undo.c (user_error): New function.
12552 (Fprimitive_undo): Use it.
12553 * print.c (print_error_message): Adjust print style for `user-error'.
12554 * keyboard.c (user_error): New function.
12555 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12557 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12559 Do not limit current-time-string to years 1000..9999.
12560 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12561 (Fcurrent_time_string): Support any year that is supported by the
12562 underlying localtime representation. Don't use asctime, as it
12563 has undefined behavior for years outside the range -999..9999.
12565 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12567 Fix race conditions involving setenv, gmtime, localtime, asctime.
12568 Without this fix, interrupts could mess up code that uses these
12569 nonreentrant functions, since setting TZ invalidates existing
12570 tm_zone or tzname values, and since most of these functions return
12571 pointers to static storage.
12572 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12573 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12574 Grow the critical sections to include not just invoking
12575 localtime/gmtime, but also accessing these functions' results
12576 including their tm_zone values if any, and any related TZ setting.
12577 (format_time_string): Last arg is now struct tm *, not struct tm **,
12578 so that the struct tm is saved in the critical section.
12579 All callers changed. Simplify allocation of initial buffer, partly
12580 motivated by the fact that memory allocation needs to be outside
12581 the critical section.
12583 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12585 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12586 with RESET_INTERVAL.
12588 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12589 Remove duplicated buffer name initialization.
12591 2012-05-02 Jim Meyering <jim@meyering.net>
12593 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12595 * xfns.c (x_window): Use xstrdup (Bug#11375).
12597 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12599 * xdisp.c (pos_visible_p): If already at a newline from the
12600 display string before the 'while' loop, don't walk back the glyphs
12601 from it3.glyph_row. Solves assertion violation when the display
12602 string begins with a newline (egg.el). (Bug#11367)
12604 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12606 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12609 2012-05-01 Glenn Morris <rgm@gnu.org>
12611 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12612 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12613 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12614 All were removed before 23.1.
12616 * dispnew.c: Remove HAVE_LIBNCURSES test;
12617 it is always true on relevant platforms.
12619 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12620 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12622 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12624 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12626 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12627 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12630 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12632 Do not avoid creating empty evaporating overlays (Bug#9642).
12633 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12634 That is, do not delete an evaporating overlay if it becomes
12635 empty after its bounds are adjusted to fit within its buffer.
12636 This fix caused other problems, and I'm reverting it until we get
12637 to the bottom of them.
12639 2012-04-27 Chong Yidong <cyd@gnu.org>
12641 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12643 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12645 * xdisp.c (pos_visible_p): If the window start position is beyond
12646 ZV, start the display from buffer beginning. Prevents assertion
12647 violation in init_iterator when the minibuffer window is scrolled
12648 via the scroll bar.
12650 * window.c (window_scroll_pixel_based): Likewise.
12652 2012-04-27 Chong Yidong <cyd@gnu.org>
12654 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12656 2012-04-27 Glenn Morris <rgm@gnu.org>
12658 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12659 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12661 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12663 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12664 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12666 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12668 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12669 display element, check also the underlying string or buffer
12670 character. (Bug#11341)
12672 * w32menu.c: Include w32heap.h.
12673 (add_menu_item): If the call to AppendMenuW (via
12674 unicode_append_menu) fails, disable Unicode menus only if we are
12675 running on Windows 9X/Me.
12677 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12679 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12680 (xgetint): Add missing shift for LSB tags.
12682 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12684 * keyboard.c (read_char): Don't wipe echo area for select window
12685 events: These might get delayed via `mouse-autoselect-window'
12688 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12690 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12691 manipulation of :loaded-from data.
12693 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12695 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12696 now a cons (bug#11311).
12698 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12700 Do not create empty overlays with the evaporate property (Bug#9642).
12701 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12702 if it becomes empty after its bounds are adjusted to fit within
12703 its buffer. Without this fix, in a nonempty buffer (let ((o
12704 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12705 yields an empty overlay that has the evaporate property, which is
12706 not supposed to happen.
12708 Fix minor GTK3 problems found by static checking.
12709 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12710 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12711 (struct _EmacsFixedClass, emacs_fixed_get_type):
12712 Move decls here from emacsgtkfixed.h, since they needn't be public.
12713 (emacs_fixed_get_type): Now static.
12714 (emacs_fixed_class_init): Omit unused local.
12715 (emacs_fixed_child_type): Remove; unused.
12716 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12717 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12718 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12719 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12720 (EMACS_FIXED_GET_CLASS): Remove; unused.
12721 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12723 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12724 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12726 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12728 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12729 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12730 (__malloc_size_t, __malloc_ptrdiff_t):
12731 Remove. All uses removed, replaced by the definiens if needed,
12732 since we can assume C89 or better now.
12733 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12741 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12742 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12743 Define using prototypes, not old style.
12744 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
12745 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
12746 (align): Don't assume that signed integer overflow wraps around.
12747 Omit unused local var.
12748 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
12749 (_free_internal_nolock, memalign, mallochook, reallochook):
12750 Omit no-longer-needed casts.
12751 (valloc): Use getpagesize, not __getpagesize.
12752 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
12753 (struct hdr): The 'magic' member is now size_t, not unsigned long.
12755 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
12757 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
12759 Move functions from C to Lisp. Make non-blocking method calls
12760 the default. Implement further D-Bus standard interfaces.
12762 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

12778 (xd_signature, xd_append_arg): Allow float for integer types.
12779 (xd_get_connection_references): New function.
12780 (xd_get_connection_address): Rename from xd_initialize.
12781 Return cached address.
12782 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
12783 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
12785 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
12786 Return number of refcounts.
12787 (Fdbus_get_unique_name): Make stronger parameter check.
12788 (Fdbus_message_internal): New defun.

12790 (Fdbus_method_return_internal, Fdbus_method_error_internal)
12791 (Fdbus_send_signal, Fdbus_register_service)

12802 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12804 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
12805 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:

12819 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
12821 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12823 * sysdep.c [__FreeBSD__]: Minor cleanups.
12824 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12825 Use Emacs indenting style more consistently. Avoid some casts.
12826 Use 'double' consistently rather than mixing 'float' and 'double'.

12830 * sysdep.c (list_system_processes, system_process_attributes):
12831 Add implementation for FreeBSD (Bug#5243).

12837 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12839 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12840 It is never used otherwise.
12842 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12844 * print.c (print_preprocess): Only check print_depth if print-circle
12846 (print_object): Check for cycles even when print-circle is nil and
12847 print-gensym is t, but only check print_depth if print-circle is nil.

12851 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12852 set the status to "failed" and ensure that sentinel is run.
12854 2012-04-20 Glenn Morris <rgm@gnu.org>
12856 * process.c (Fset_process_inherit_coding_system_flag)
12857 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12867 farther than the first row after the header line, if any.
12868 Don't consider the header-line row as "partially visible", even if
12869 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
12871 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

12881 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
12882 (ALL_CFLAGS): Use new macros rather than old.
12883 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

12885 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12886 -Wunused-result, -Wunused-variable. This should go away once
12887 the Emacs and Gnulib regex code is merged.
12888 (xmalloc, xrealloc): Now static.
12890 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

12907 New extern decls, to avoid calling undeclared functions.
12908 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12909 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12910 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12911 (NEED_MEM_INSERT): New macro.
12912 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12913 Remove one incorrect comment and fix another.

12927 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12928 Remove decls. This fixes an "It stinks!".
12930 * alloc.c (which_symbols): Fix alignment issue / type clash.
12932 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12934 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12935 (struct Lisp_Misc_Any): Likewise.
12936 (struct Lisp_Free): Likewise.
12937 * alloc.c (union aligned_Lisp_Symbol): Define.

12948 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12949 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12950 * s/netbsd.h, s/sol2-6.h:
12951 Remove definition of GC_MARK_STACK, since the default now works.
12952 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12953 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12954 no longer the default.
12955 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12957 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12959 * lread.c (lisp_file_lexically_bound_p):

12962 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12964 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12965 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

12976 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12978 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12980 2012-04-11 Daniel Colascione <dancol@dancol.org>
12982 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12983 against is gone. It's better to use vfork now so that when Cygwin
12984 gains a new, working vfork, we use it automatically (bug#10398).
12986 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12988 * window.c (save_window_save): Obey window-point-insertion-type.

13006 * w32.c (w32_delayed_load): Record the full path of the library
13007 being loaded (bug#10424).
13009 2012-04-09 Glenn Morris <rgm@gnu.org>
13011 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13012 not just in the obarray, before snarfing them. (Bug#11036)

13029 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13030 attempts per process (connection).
13032 2012-04-09 Chong Yidong <cyd@gnu.org>
13034 * eval.c (Fuser_variable_p, user_variable_p_eh)
13035 (lisp_indirect_variable): Functions deleted.
13036 (Fdefvar): Caller changed.
13038 * callint.c (Finteractive, Fcall_interactively):
13039 * minibuf.c (Fread_variable): Callers changed.
13041 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13043 * xdisp.c (set_cursor_from_row): If the display string appears in
13044 the buffer at position that is closer to point than the position
13045 after the display string, display the cursor on the first glyph of
13046 the display string. Fixes cursor display when a 'display' text
13047 property immediately follows invisible text. (Bug#11094)
13049 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13051 composite.c: use 'double' consistently
13052 * composite.c (get_composition_id): Use 'double' consistently
13053 instead of converting 'float' to 'double' and vice versa; this is
13054 easier to understand and avoids a GCC warning.
13056 2012-04-09 Glenn Morris <rgm@gnu.org>
13058 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13059 preparation for dumping it with emacs. (Bug#4789)

13081 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13082 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13083 objects, as mark_maybe_pointer will catch them otherwise.

13097 (GLOBAL_SOURCES): Add xml.c.
13098 ($(BLD)/xml.$(O)): New dependency list.
13100 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13101 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13102 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13103 [!WINDOWSNT]: New macros.
13104 (init_libxml2_functions, libxml2_loaded_p): New functions.
13105 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13106 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13107 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13108 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13110 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13111 Call init_libxml2_functions before calling libxml2 functions.
13112 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13114 * emacs.c: Don't include libxml/parser.h.
13115 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13116 xmlCleanupParser directly.

13120 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13122 * indent.c (Fvertical_motion): If there is a display string at
13123 point, use it.vpos to compute how many lines to backtrack after
13124 move_it_to point. (Bug#11133)
13126 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13128 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13129 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13130 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13131 macros related to unification of CJK characters. For the details,
13132 see the discussion following the message here:
13133 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13135 2012-04-04 Chong Yidong <cyd@gnu.org>
13137 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13139 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13141 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

13149 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13151 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13152 position we get to after a call to move_it_to fails the
13153 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13154 only if we wind up in a string from display property. (Bug#11063)
13156 * window.c (Fdelete_other_windows_internal): Invalidate the row
13157 and column information about mouse highlight, so that redisplay
13158 restores it after reallocating the glyph matrices. (Bug#7464)
13160 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13161 string comes from a `display' text property, use the buffer
13162 position of that property as if we actually saw that position in
13164 (move_it_by_lines): Remove the assertion that
13165 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13166 violated when there's a before-string at the beginning of a line.
13169 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13171 * xdisp.c (append_space_for_newline): If the default face was

13173 (extend_face_to_end_of_line): Use the remapped default face for
13174 extending the face to the end of the line.
13175 (display_line): Call extend_face_to_end_of_line when the default
13176 face was remapped. (Bug#11068)
13178 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13180 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

13198 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13199 (command_loop_1): Use it; inhibit selection update for

13204 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13206 2012-03-25 Kenichi Handa <handa@m17n.org>
13208 * dispextern.h (struct glyph): Change the bit length of
13209 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13211 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13213 * s/ms-w32.h (tzname): Include time.h before redirecting to

13224 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13226 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13227 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13228 when fetching a multibyte character consumes more bytes than
13229 CHAR_BYTES returns, due to unification of CJK characters in
13230 string_char. (Bug#11073)
13232 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13234 * process.c (wait_reading_process_output): Handle pty disconnect
13235 by refraining from sending oneself a SIGCHLD (bug#10933).
13237 2012-03-22 Chong Yidong <cyd@gnu.org>
13239 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13241 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13242 Mark string as coming from a prefix property.

13266 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13268 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13269 that is not from display property, accept the row as a "cursor
13270 row" if one of the string's character has a non-nil `cursor'
13271 property. Fixes cursor positioning when there are newlines in
13272 overlay strings, e.g. in icomplete.el. (Bug#11035)
13274 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

13305 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13308 2012-03-03 Glenn Morris <rgm@gnu.org>
13310 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13312 2012-03-02 Eli Zaretskii <eliz@gnu.org>

13315 position past the first glyph_row that ends at ZV. (Bug#10902)
13316 (redisplay_window, next_element_from_string): Fix typos in
13318 (redisplay_window): Pass to move_it_vertically the margin in
13319 pixels, not in screen lines.
13321 2012-03-02 Glenn Morris <rgm@gnu.org>
13323 * buffer.c (buffer-list-update-hook): Doc fix.
13325 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13327 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13328 push_it before setting up the iterator for the first overlay
13329 string, even if we have an empty string loaded.
13330 (next_overlay_string): If there's an empty string on the iterator
13331 stack, pop the stack. (Bug#10903)
13333 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13335 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13336 Suggested by Stefan Monnier in
13337 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13338 * alloc.c (widen_to_Lisp_Object): New static function.
13339 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13340 and widening them to Lisp_Objects. This would work even if
13341 USE_LSB_TAG is defined and wide integers are used, which might
13342 happen in a future version of Emacs.
13344 2012-02-25 Chong Yidong <cyd@gnu.org>
13346 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

13351 before saving to clipboard manager.
13353 2012-02-24 Chong Yidong <cyd@gnu.org>
13355 * keyboard.c (process_special_events): Handle all X selection
13356 requests in kbd_buffer, not just the next one (Bug#8869).
13358 2012-02-23 Chong Yidong <cyd@gnu.org>
13360 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13361 call when setting menu-bar-lines and tool-bar-lines parameters.
13362 (unwind_create_frame_1): New helper function.
13364 * window.c (inhibit_window_configuration_change_hook): New var.
13365 (run_window_configuration_change_hook): Obey it.

13383 when computing $valmask.
13385 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13386 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13387 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13388 It's useless in that case, and it can cause problems on hosts
13389 that allocate halves of EMACS_INT values separately.
13390 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13391 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13392 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13393 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13394 it avoids undefined behavior on hosts where shifting right by more
13395 than the word width has undefined behavior.
13397 2012-02-19 Chong Yidong <cyd@gnu.org>
13399 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13400 (Funhandled_file_name_directory, Ffile_name_as_directory)
13401 (Fdirectory_file_name, Fexpand_file_name)
13402 (Fsubstitute_in_file_name): Protect against invalid file handler
13403 return values (Bug#10845).

13417 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13419 2012-02-15 Chong Yidong <cyd@gnu.org>
13421 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13422 marked as special. Also, starting docstrings with * is obsolete.

13437 2012-02-12 Chong Yidong <cyd@gnu.org>
13439 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13440 as that creates a dangerous corner case.
13442 * window.c (Fdelete_window_internal): Invalidate the mouse
13443 highlight (Bug#9904).
13445 2012-02-12 Glenn Morris <rgm@gnu.org>

13450 * nsselect.m (Fx_own_selection_internal)
13451 (Fx_disown_selection_internal, Fx_selection_exists_p)
13452 (Fx_selection_owner_p, Fx_get_selection_internal):
13453 Sync docs and argument specs with the xselect.c versions.
13455 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

13475 2012-02-07 Chong Yidong <cyd@gnu.org>
13477 * buffer.c (Fbuffer_local_variables)
13478 (buffer_lisp_local_variables): Handle unbound vars correctly;
13479 don't let Qunbound leak into Lisp.
13481 2012-02-07 Glenn Morris <rgm@gnu.org>
13483 * image.c (Fimagemagick_types): Doc fix.
13485 * image.c (imagemagick-render-type): Change it from a lisp object
13486 to an integer. Move the doc here from the lisp manual.

13503 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13505 * w32.c (get_emacs_configuration_options):
13506 Include --enable-checking, if specified, in the return value.

13516 before BEGV. (Bug#10696)
13518 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13520 Handle overflow when computing char display width (Bug#9496).
13521 * character.c (char_width): Return EMACS_INT, not int.
13522 (char_width, c_string_width): Check for overflow when
13523 computing the width; this is possible now that individual
13524 characters can have unbounded width. Problem introduced
13525 by merge from Emacs 23 on 2012-01-19.

13549 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13551 (x_produce_glyphs): If the component of a composition is a null

13556 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13557 first 2 arguments are identical. This makes inserting large
13558 output from a subprocess an order of magnitude faster on
13559 MS-Windows, where all sbrk'ed memory is always contiguous.
13561 2012-01-31 Glenn Morris <rgm@gnu.org>

13658 * xdisp.c (rows_from_pos_range): Accept additional argument
13659 DISP_STRING, and accept any glyph in a row whose object is that
13660 string as eligible for mouse highlight. Fixes mouse highlight of
13661 display strings from overlays. (Bug#10464)
13663 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
13665 emacs: fix an auto-save permissions race condition (Bug#10400)

13667 (Fmake_directory_internal): Use it.
13668 (do_auto_save_make_dir): Set it, instead of invoking chmod after

13672 (Fdo_auto_save): Catch all errors, not just file errors, so
13673 that the var is always cleared.

14178 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14179 is set, removing the need for VIRT_ADDRESS_VARIES.
14180 (PURE_P): Use a more-efficient implementation that needs just one

14183 to 4 (xorl, subq, cmpq, setbe).
14184 * alloc.c (pure): Always extern now, since that's the

14195 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14196 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14197 behave as if the cursor position were at the window margin.
14199 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14200 and the cursor position is out of bounds, behave as if the cursor
14201 position were at the window margin. (Bug#10075)
14203 2011-11-18 Chong Yidong <cyd@gnu.org>
14205 * window.c (Fwindow_combination_limit): Make first argument

14278 Fixes assertion violations in row_equal_p. (Bug#10035)
14280 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

14421 Otherwise, these inline functions do not conform to C99 and
14422 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14423 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14424 * intervals.c (adjust_intervals_for_insertion)

14427 (static_offset_intervals): Remove.
14428 (offset_intervals): Rewrite using the old contents of
14429 static_offset_intervals. The old version didn't conform to C99
14430 because an extern inline function contained a reference to an
14431 identifier with static linkage.

14676 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14677 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14678 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14679 (Fmove_to_window_line): Doc fix.
14681 2011-10-27 Chong Yidong <cyd@gnu.org>
14683 * process.c (make_process): Set gnutls_state to NULL.
14685 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14686 non-NULL, regardless of GNUTLS_INITSTAGE.
14687 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14688 an error. Set process slots as soon as we allocate them.
14690 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14692 2011-10-27 Chong Yidong <cyd@gnu.org>
14694 * gnutls.c (emacs_gnutls_deinit): New function.
14695 Deallocate credentials structures as well as calling gnutls_deinit.
14696 (Fgnutls_deinit, Fgnutls_boot): Use it.
14698 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14699 (deactivate_process): Call emacs_gnutls_deinit.
14701 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14703 * image.c (x_create_x_image_and_pixmap):
14704 * w32.c (sys_rename, w32_delayed_load):
14705 * w32font.c (fill_in_logfont):
14706 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14708 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14710 * w32fns.c (w32_default_color_map): New function,
14711 extracted from Fw32_default_color_map.
14712 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14714 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14716 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14718 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14720 * keyboard.c (test_undefined): New function (bug#9751).
14721 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14723 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14725 * sysdep.c (init_sys_modes): Fix the check for the controlling
14726 terminal (Bug#6649).
14728 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14730 * dispextern.h (struct bidi_it): New member next_en_type.
14732 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14733 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14734 current character, check also for next_en_type being WEAK_EN.
14735 (bidi_resolve_weak): Don't enter the expensive loop if the current
14736 position is before next_en_pos. Record the bidi type of the first
14737 non-ET, non-BN character we find, in addition to its position.
14738 (bidi_level_of_next_char): Invalidate next_en_type when
14739 next_en_pos is over-stepped.
14741 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14743 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14744 * editfns.c: Rewrite current-time-zone so that it invokes
14745 the equivalent of (format-time-string "%Z") to get the time zone name.
14746 This fixes a bug when the time zone name contains characters that
14747 need converting from the system time locale to Emacs internal format.
14748 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14749 that patch fixed format-time-string to do the conversion, but
14750 I forgot to fix current-time-zone.
14751 (format_time_string): New function, containing most of
14752 what Fformat_time_string used to contain.
14753 (Fformat_time_string): Rewrite in terms of format_time_string.
14754 This doesn't change this function's behavior.
14755 (current-time-zone): Rewrite to use format_time_string.
14756 This fixes the bug reported by Michael Schierl in
14757 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14758 Jason Rumney's 2007-06-07 change worked around this bug, but
14760 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14762 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14764 * xdisp.c (start_display): If the character at POS is displayed
14765 via a display vector, reset IT->current.dpvec_index to zero.
14766 (try_window_reusing_current_matrix): If a line ends in a display
14767 vector or the next line starts in a display vector, continue
14768 redrawing the window even though the character position of
14769 start_row was reached.
14772 2011-10-18 Chong Yidong <cyd@gnu.org>
14774 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14775 with nobreak-char-display too.
14777 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14779 Fix part 3 of bug#9771.
14780 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14781 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14782 non-neutral characters if the current character is a paragraph
14783 separator (a.k.a. Newline). This avoids running the same
14784 expensive loop twice, once when we consume the preceding newline
14785 and the other time when the line actually needs to be displayed.
14786 Avoid the loop when we see neutrals on the base embedding level
14787 following a character whose directionality is the same as the
14788 paragraph's. This avoids running the expensive loop when a line
14789 ends in a long sequence of neutrals, like control characters.
14790 Add assertion against STRONG_AL type. Slightly rearrange code
14791 that determines the type of a neutral given the first non-neutral
14793 (bidi_level_of_next_char): Set next_en_pos to zero when
14794 invalidating its info.
14796 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14798 * xdisp.c (push_display_prop): Determine whether to record string
14799 or buffer position by IT->string, not by IT->method. Allow
14800 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14801 (move_it_vertically_backward): Don't look for character position
14802 immediately after the newline when in a continuation line.
14805 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14807 * window.c (coordinates_in_window): Rewrite and delabelize
14808 vertical border check. (Bug#5357) (Bug#9618)
14810 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14812 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14813 errors in XSetWindowBorder (bug#9310).
14815 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14817 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14818 avoid crash when xmalloc overrun checking is enabled.
14820 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14822 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14823 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14824 cursor motion with <left> and <right> arrow keys.
14826 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14827 some callers set that themselves.
14829 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14831 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14832 display string and the previous row comes from the same string and
14833 is empty. (Bug#9739) (Bug#9738)
14835 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14837 * doc.c (get_doc_string): Encode file name (bug#9735).
14839 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14841 * bidi.c (bidi_level_of_next_char):
14842 * xdisp.c (get_visually_first_element): Remove old incorrect
14843 comments regarding the Unicode Line Separator character.
14845 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14847 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14849 * alloc.c (Fgc_status): Do not access beyond zombies array
14850 boundary if nzombies > MAX_ZOMBIES.
14851 * alloc.c (dump_zombies): Add missing format specifier.
14853 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14855 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14856 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14858 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14859 Some packages use them to denote characters with modifiers.
14861 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14863 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14864 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14865 matching a pp-number. Rename parameter var to var1.
14867 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14869 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14871 2011-10-08 Glenn Morris <rgm@gnu.org>
14873 * callint.c (Fcall_interactively): Give a more explicit error for the
14874 'c' case with a non-character input. (Bug#8479)
14876 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14878 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14880 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14881 lines that are hscrolled on the left.
14883 * dispnew.c (buffer_posn_from_coords): Account for a possible
14884 presence of header-line. (Bug#4426)
14886 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14888 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14889 Don't advertise functionality which we discourage or doesn't work.
14891 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14893 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14894 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14895 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14896 this makes Emacs dump core during garbage collection on rare
14897 occasions. sizeof is obviously inferior to offsetof here, so
14898 stick with offsetof.
14899 (GC_POINTER_ALIGNMENT): New macro.
14900 (mark_memory): Omit 3rd (offset) arg; caller changed.
14901 Don't assume EMACS_INT alignment is the same as pointer alignment.
14903 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14905 * keyboard.c (read_key_sequence_remapped): New var.
14906 (read_key_sequence): Compute remapping in the right buffer.
14907 (command_loop_1): Use read_key_sequence's remapping directly.
14909 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14911 * dired.c (file_name_completion): Don't expand file name.
14912 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14913 before checking file name handler.
14915 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14916 they've been requested explicitly (bug#9591).
14918 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14920 * keymap.c (Fsingle_key_description): Use make_specified_string
14921 instead of build_string to build string from push_key_description.
14924 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14926 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14927 This fixes a Y2038 bug on 64-bit hosts.
14928 * buffer.c (reset_buffer):
14929 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14930 (Fclear_buffer_auto_save_failure):
14931 Use 0, not -1, to represent an unset failure time, since time_t
14932 might not be signed.
14934 Remove dependency on glibc malloc internals.
14935 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14936 Move back here from lisp.h, but with their new implementations.
14937 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14938 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14939 * charset.c (charset_table_init): New static var.
14940 (syms_of_charset): Use it instead of xmalloc. This removes a
14941 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14942 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14943 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14944 Move back to alloc.c.
14945 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14946 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14948 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14950 * nsterm.m (windowDidResize): Call x_set_window_size only when
14951 ns_in_resize is true. Otherwise set pixelwidth/height and
14952 call change_frame_size (Bug#9628).
14954 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14956 Port --enable-checking=all to Fedora 14 x86-64.
14957 * charset.c (syms_of_charset): Also account for glibc malloc's
14958 internal overhead when calculating the initial malloc maximum.
14960 Port --enable-checking=all to Fedora 14 x86.
14961 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14963 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14964 (overrun_check_realloc, overrun_check_free):
14965 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14966 That way, xmalloc returns a properly-aligned pointer even if
14967 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14968 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14969 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14970 into account when calculating the initial malloc maximum.
14971 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14972 Move here from alloc.c, so that charset.c can use it too.
14973 Properly align; the old code wasn't right for common 32-bit hosts
14974 when configured with --enable-checking=all.
14975 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14976 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14978 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14980 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14983 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14985 * xdisp.c (compute_display_string_end): If there's no display
14986 string at CHARPOS, return -1.
14988 * bidi.c (bidi_fetch_char): When compute_display_string_end
14989 returns a negative value, treat the character as a normal
14990 character not covered by a display string. (Bug#9624)
14992 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14994 * lread.c (Fread_from_string): Fix typo in docstring.
14996 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14998 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14999 newline, reseat the iterator instead of bidi-iterating there one
15000 character at a time. (Bug#9610)
15001 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15002 TO_CHARPOS if the bidi iterator is at base embedding level.
15004 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15006 * lread.c (readevalloop): Use correct code for NBSP.
15007 (read1): Likewise. (Bug#9608)
15009 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15011 * dbusbind.c (Fdbus_register_signal): When service is not
15012 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15014 2011-09-25 Glenn Morris <rgm@gnu.org>
15016 * buffer.c (truncate-lines): Doc fix.
15018 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15020 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15021 (Fset_window_next_buffers): Doc fix.
15023 2011-09-24 Glenn Morris <rgm@gnu.org>
15025 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15027 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15029 Fix minor problems found by static checking.
15030 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15031 * indent.c (Fvertical_motion): Fix == vs = typo.
15033 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15035 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15036 Default value is now t. Doc fix.
15038 * indent.c (Fvertical_motion): Compute and apply the overshoot
15039 logic when moving up, not only when moving down. Fix the
15040 confusing name and values of the it_overshoot_expected variable;
15041 logic changes accordingly. (Bug#9254) (Bug#9549)
15043 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15044 CHARPOS is covered by a display string which includes newlines.
15045 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15046 is covered by a display string with embedded newlines.
15048 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15050 * dbusbind.c (Fdbus_register_signal): Add match rule to
15051 Vdbus_registered_objects_table. (Bug#9581)
15052 (Fdbus_register_method, Vdbus_registered_objects_table):
15055 2011-09-24 Jim Meyering <meyering@redhat.com>
15057 do not ignore write error for any output size
15058 The previous change was incomplete.
15059 While it makes emacs --batch detect the vast majority of stdout
15060 write failures, errors were still ignored whenever the output size is
15061 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15062 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15063 && echo FAIL: ignored write error
15064 FAIL: ignored write error
15065 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15066 && echo FAIL: ignored write error
15067 FAIL: ignored write error
15068 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15070 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15072 * emacs.c (Fkill_emacs): In noninteractive mode exit
15073 non-successfully if a write error occurred on stdout. (Bug#9574)
15075 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15077 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15080 * dispextern.h (struct it): Update the comment documenting what
15083 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15085 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15086 a display string, extend search for cursor position to end of row.
15087 (find_row_edges): If the row ends in a newline from a display
15088 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15089 Handle the case of a display string with multiple newlines.
15090 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15091 non-empty line. Fixes confusing cursor motion with arrow keys at
15092 the beginning of a line that starts with whitespace.
15094 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15096 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15099 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15101 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15102 boolean (Bug#9154).
15104 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15106 * xdisp.c (display_line): Record maximum and minimum buffer
15107 positions even if no glyphs were produced (e.g., by a zero-width
15108 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15109 buffer positions that will be removed from the glyph row because
15111 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15112 column is beyond frame width: don't subtract 1 "pixel" when
15113 computing width of the stretch.
15114 (reseat_at_next_visible_line_start): Undo the change made on
15115 2011-09-17 that saved paragraph information and restored it after
15116 the call to `reseat'. (Bug#9545)
15118 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15120 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15121 and turn window cursor on if cleared (Bug#9415).
15123 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15125 * search.c (boyer_moore): Take unibyte characters from pattern
15126 literally. (Bug#9458)
15128 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15130 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15132 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15134 Fix minor problem found by static checking.
15135 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15136 initialized, to pacify gcc -Wuninitialized.
15138 * fileio.c: Report proper errno when syscall falls.
15139 (Finsert_file_contents): Save and restore errno,
15140 so that report_file_error outputs the correct diagnostic.
15141 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15143 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15145 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15147 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15149 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15150 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15152 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15154 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15155 about the current paragraph and restore it after the call to reseat.
15157 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15158 (bidi_find_paragraph_start): Search back for paragraph beginning
15159 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15160 (bidi_move_to_visually_next): Only trigger paragraph-related
15161 computations when the last character is a newline or at EOB, not
15162 just any NEUTRAL_B. (Bug#9470)
15164 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15165 truncated lines if point is covered by a display string. (Bug#9524)
15167 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15169 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15170 (cons_to_x_long): New function.
15171 (lisp_data_to_selection_data): Use it. Correct the test for
15172 short-versus-long data; it was negated. Break out of vector
15173 loop, for efficiency, when a long datum is discovered.
15175 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15177 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15179 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15181 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15182 GCC PR/17406) by declaring this function with external scope.
15184 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15186 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15187 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15189 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15191 * editfns.c (Fformat): Correctly handle text properties on "%%".
15193 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15195 * xterm.c (x_draw_composite_glyph_string_foreground):
15196 * w32term.c (x_draw_composite_glyph_string_foreground):
15197 * term.c (encode_terminal_code):
15198 * composite.c (composition_update_it, get_composition_id):
15199 * xdisp.c (get_next_display_element)
15200 (fill_composite_glyph_string): Add comments about special meaning
15201 of TAB characters in a composition.
15203 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15205 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15206 This occurs when processing a multibyte format.
15207 Problem reported by Wolfgang Jenker.
15209 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15211 * xdisp.c (try_cursor_movement): Only check for exact match if
15212 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15214 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15216 Remove unused external symbols.
15217 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15218 * xdisp.c (calc_pixel_width_or_height): Now static.
15219 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15220 * indent.c (check_display_width):
15221 * w32term.c: Fix comment to match code.
15222 * xterm.c, xterm.h (x_catching_errors): Remove.
15224 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15226 * xselect.c: Use signed conversions more consistently (Bug#9498).
15227 (selection_data_to_lisp_data): Assume incoming selection data are
15228 signed integers, not unsigned. This is to be consistent with
15229 outgoing selection data, which was modified to use signed integers
15230 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15231 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15232 expects long, not unsigned long.
15234 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15236 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15237 computation of loop end. Reported by Johan Bockgård
15240 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15242 * frame.c (Fother_visible_frames_p): Function deleted.
15244 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15246 * indent.c (compute_motion): Process display vector front to back
15247 rather than the other way around. (Bug#2496)
15249 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15251 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15253 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15255 * minibuf.c (Fread_from_minibuffer): Doc fix.
15257 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15259 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15260 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15262 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15264 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15265 value for non-existent files.
15267 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15269 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15270 set its "size" to -1. This will set the modtime_size field of
15271 the corresponding buffer to -1, which is what
15272 verify-visited-file-modtime expects for files that do not exist.
15275 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15277 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15279 * lisp.h: ... from here. push_key_description is no longer
15280 defined in keyboard.c, so its declaration should not be in
15281 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15282 logically belongs with push_key_description.
15284 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15286 * buffer.h: Include <sys/types.h> instead of <time.h>.
15287 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15288 Problem reported by Herbert J. Skuhra.
15290 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15292 * xml.c (parse_region): Make the parsing work for
15293 non-comment-starting XML files again (bug#9144).
15295 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15297 * image.c (gif_load): Fix calculation of bottom and right corner.
15300 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15302 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15303 redisplay in small windows.
15305 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15307 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15309 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15311 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15312 Operate on live windows only.
15314 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15316 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15318 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15320 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15321 only under bidi iteration.
15323 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15325 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15327 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15329 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15330 Without this fix, the command to link temacs failed due to an
15331 undefined symbol __builtin_isnan. This is because
15332 /usr/include/iso/math_c99.h #defines isnan(x) to
15333 __builtin_isnan(x), but the bundled gcc, which identifies itself
15334 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15336 * floatfns.c (isnan): #undef, and then #define to a clone of
15338 (Fisnan): Always define, since it's always available now.
15339 (syms_of_floatfns): Always define isnan at the Lisp level.
15341 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15343 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15345 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15347 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15348 The previous code assumed that file offsets (off_t values) fit in
15349 EMACS_INT variables, which is not true on typical 32-bit hosts.
15350 The code messed up by falsely reporting buffer overflow in cases
15351 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15352 when "big" contains more than 2**29 bytes, even though this
15353 inserts just one byte and does not overflow the buffer.
15354 (Finsert_file_contents): Store file offsets as off_t
15355 values, not as EMACS_INT values. Check for overflow when
15356 converting between EMACS_INT and off_t. When checking for
15357 buffer overflow or for overlap, take the offsets into account.
15358 Don't use EMACS_INT for small values where int suffices.
15359 When checking for overlap, fix a typo: ZV was used where
15360 ZV_BYTE was intended.
15361 (Fwrite_region): Don't assume off_t fits into 'long'.
15362 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15364 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15366 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15368 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15370 sprintf-related integer and memory overflow issues (Bug#9412).
15372 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15373 (esprintf, exprintf, evxprintf): New functions.
15374 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15375 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15376 (modify_event_symbol): Do not assume that the length of
15377 name_alist_or_stem is safe to alloca and fits in int.
15378 (Fexecute_extended_command): Likewise for function name and binding.
15379 (Frecursion_depth): Wrap around reliably on integer overflow.
15380 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15381 since some callers pass EMACS_INT values.
15382 (Fsingle_key_description): Don't crash if symbol name contains more
15383 than MAX_ALLOCA bytes.
15384 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15385 (get_minibuffer): Arg is now EMACS_INT, not int.
15386 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15387 (esprintf, exprintf, evxprintf): New decls.
15388 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15390 * dbusbind.c (signature_cat): New function.
15391 (xd_signature, Fdbus_register_signal):
15392 Do not overrun buffer; instead, report string overflow.
15394 * dispnew.c (add_window_display_history): Don't overrun buffer.
15395 Truncate instead; this is OK since it's just a log.
15397 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15398 even if the time zone offset is outlandishly large.
15399 Don't mishandle offset == INT_MIN.
15401 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15402 when creating daemon; the previous buffer-overflow check was incorrect.
15404 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15405 which has the guts of the old verror function.
15407 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15408 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15410 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15411 (font_unparse_xlfd): Don't blindly alloca long strings.
15412 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15413 fits in int, when using sprintf. Use single snprintf to count
15414 length of string rather than counting it via multiple sprintfs;
15415 that's simpler and more reliable.
15416 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15417 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15418 sprintf, in case result does not fit in int.
15420 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15421 (fontset_from_font): Print it.
15423 * frame.c (tty_frame_count): Now printmax_t, not int.
15424 (make_terminal_frame, set_term_frame_name): Print it.
15425 (x_report_frame_params): In X, window IDs are unsigned long,
15426 not signed long, so print them as unsigned.
15427 (validate_x_resource_name): Check for implausibly long names,
15428 and don't assume name length fits in 'int'.
15429 (x_get_resource_string): Don't blindly alloca invocation name;
15430 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15433 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15434 (xg_check_special_colors, xg_set_geometry):
15435 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15437 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15438 Use esprintf, not sprintf, in case result does not fit in int.
15440 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15441 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15442 it as a large positive number.
15443 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15444 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15446 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15447 in case result does not fit in int.
15449 * print.c (float_to_string): Detect width overflow more reliably.
15450 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15451 buffer overrun. Don't assume list length fits in 'int'. Treat
15452 print length of 0 as 0, not as infinity; to be consistent with other
15453 uses of print length in this function. Don't overflow print length
15454 index. Don't assume hash table size fits in 'long', or that
15455 vectorlike size fits in 'unsigned long'.
15457 * process.c (make_process): Use printmax_t, not int, to format
15458 process-name gensyms.
15460 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15462 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15463 to avoid potential buffer overrun.
15465 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15466 if X resource line is longer than 512 bytes.
15468 * xfns.c (x_window): Make sprintf buffer a bit bigger
15469 to avoid potential buffer overrun.
15471 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15473 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15475 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15477 Integer overflow fixes for scrolling, etc.
15478 Without these, Emacs silently mishandles large integers sometimes.
15479 For example, "C-u 4294967297 M-x recenter" was treated as if
15480 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15482 * xdisp.c (try_window_id): Check Emacs fixnum range before
15483 converting to 'int'.
15485 * window.c (window_scroll_line_based, Frecenter):
15486 Check that an Emacs fixnum is in range before assigning it to 'int'.
15487 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15488 values converted from Emacs fixnums.
15489 (Frecenter): Don't wrap around a line count if it is out of 'int'
15490 range; instead, treat it as an extreme value.
15491 (Fset_window_configuration, compare_window_configurations):
15492 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15494 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15495 that can exceed INT_MAX. Check that EMACS_INT value is in range
15496 before assigning it to the (possibly-narrower) index.
15497 (match_limit): Don't assume that a fixnum can fit in 'int'.
15499 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15502 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15503 (Fvertical_motion): Don't wrap around LINES values that don't fit
15504 in 'int'. Instead, treat them as extreme values. This is good
15505 enough for windows, which can't have more than INT_MAX lines anyway.
15507 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15509 * Require libxml/parser.h to avoid compilation warning.
15511 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15513 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15514 since this reportedly can destroy thread storage.
15516 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15518 * syntax.c (find_defun_start): Update all cache variables if
15519 exiting early (Bug#9401).
15521 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15523 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15525 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15526 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15527 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15529 * term.c (tty_append_glyph): New function.
15530 (produce_stretch_glyph): Static function and its prototype deleted.
15532 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15535 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15537 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15538 when checking :margin (Bug#9390).
15539 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15540 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15541 so that the name doesn't mislead. All uses changed.
15543 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15545 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15548 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15550 * xdisp.c (move_it_to): Don't bail out early when reaching
15551 position beyond to_charpos, if we are scanning backwards.
15552 (move_it_vertically_backward): When DY == 0, make sure we get to
15553 the first character in the line after the newline.
15555 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15557 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15558 (ccl_driver): Do not generate an out-of-range pointer.
15559 (Fccl_execute_on_string): Remove unnecessary check for
15560 integer overflow, noted by Stefan Monnier in
15561 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15562 Remove a FIXME that didn't need fixing.
15563 Simplify the newly-introduced buffer reallocation code.
15565 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15567 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15569 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15571 Integer and memory overflow issues (Bug#9196).
15573 * doc.c (get_doc_string): Rework so that
15574 get_doc_string_buffer_size is the actual buffer size, rather than
15575 being 1 less than the actual buffer size; this makes xpalloc more
15578 * image.c (x_allocate_bitmap_record, cache_image):
15579 * xselect.c (Fx_register_dnd_atom):
15580 Simplify previous changes by using xpalloc.
15582 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,

15587 (charset_compare): Don't overflow if priorities differ greatly.
15588 (Fsort_charsets): Don't assume list length fits in int.
15589 Check for size-calculation overflow when allocating sort data.
15590 (syms_of_charset): Allocate an initial charset table that is
15591 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15593 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15595 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15596 The actual value is always <= INT_MAX, and leaving it unsigned made

15599 * dispextern.h (struct glyph_matrix.rows_allocated)
15600 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15601 with xpalloc. The values are still always <= INT_MAX.

15610 (set_cache_region, invalidate_region_cache)
15611 (revalidate_region_cache, know_region_cache, region_cache_forward)
15612 (region_cache_backward, pp_cache):
15613 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15614 so that ptrdiff_t * can be passed to xpalloc.
15615 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15616 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

15631 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15633 Don't update size of array until after memory allocation succeeds,
15634 because xmalloc/xrealloc may not return.
15635 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15636 now that we have proper integer overflow checking.
15637 (record_overlay_string, overlay_strings): Catch overflows when
15638 calculating size of overlay_str_buf.
15640 * callproc.c (Fcall_process): Check for size overflow when
15641 calculating size of args2.
15642 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15643 Normally we prefer signed values, but sticking with ptrdiff_t would
15644 require adding more-complicated checks.
15646 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15647 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15648 Redo buffer-overflow calculations to avoid integer overflow.
15649 Add a FIXME comment where memory seems to be over-allocated.
15651 * character.c (Fstring): Check for size-calculation overflow.
15653 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15654 unnecessary integer overflow. Check for size overflow.

15686 Don't assume message length fits in int.
15687 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15689 * emacs.c (main): Do not reallocate argv, since there is a null at
15690 the end that can be overwritten, and this way there's no need to
15691 worry about size-calculation overflow.
15692 (sort_args): Check for size-calculation overflow.
15694 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15696 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15698 * frame.c (set_menu_bar_lines, x_set_frame_parameters)

15700 Check for integer overflow.
15701 (x_set_alpha): Do not assume XINT fits in int.
15703 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15704 This is for the members text_lines, text_cols, total_lines, total_cols,
15705 where the system imposes an 'int' limit.
15707 * fringe.c (Fdefine_fringe_bitmap):
15708 Don't update size until alloc works.

15713 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15714 Check for size-calculation overflow.
15715 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15716 do, as we prefer signed integers.
15717 (id_to_widget.max_size, id_to_widget.used)
15718 (xg_store_widget_in_map, xg_remove_widget_from_map)

15721 Use and return ptrdiff_t, not int.
15722 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15723 * gtkutil.h: Change prototypes to match the above.
15725 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15726 are duplicate now that they've been promoted to lisp.h.
15727 (x_allocate_bitmap_record, x_alloc_image_color)
15728 (make_image_cache, cache_image, xpm_load):

15772 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15773 for command line length. Do not attempt to address one before the
15774 beginning of an array, as that's not portable.
15776 * term.c (max_frame_lines): Remove; unused.

15802 Use ptrdiff_t, not int, for sizes.
15803 (Finternal_make_lisp_face, cache_face):
15804 Check for size calculation overflow.
15805 (cache_face): Treat size calculation overflows as if they were

15809 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15810 sizes, since they can exceed INT_MAX in size. Check for size

15815 Don't update size until alloc done.
15817 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15818 as sprintf is limited to int lengths.
15820 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15821 (X_LONG_MIN): New macros.
15822 Use them to make the following changes clearer.
15823 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15824 This change doesn't affect the value now, but it may help remind
15825 future maintainers not to raise the value too much later.
15826 (SELECTION_QUANTUM): Remove, replacing with ...
15827 (selection_quantum): ... new function, which avoids overflow.
15829 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15830 assumption that selection length fits in 'int'.

15847 Don't store size until memory allocation succeeds.
15848 (x_get_window_property): Plug memory leak on memory exhaustion.
15849 Don't double-block input; malloc is safe here. Don't assume 2**34
15850 - 4 fits in unsigned long. Add an xassert to check
15851 XGetWindowProperty overflow. Be more careful about overflow
15852 calculations, and distinguish size from memory overflow better.
15853 (receive_incremental_selection): When tracing, don't assume
15854 unsigned int is less than INT_MAX.
15855 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15856 harmful) conversions of unsigned short to int.
15857 (lisp_data_to_selection_data): Don't assume that integers
15858 in the range -65535 through -1 fit in an X unsigned short.
15859 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15860 result parameters unless successful. Rely on cons_to_unsigned
15861 to report problems with elements; the old code wasn't right anyway.
15862 (x_check_property_data): Check for int overflow; we cannot use
15863 a wider type due to X limits.

15896 * lisp.h (hash_lookup, hash_put):
15897 * minibuf.c (Ftest_completion):
15898 Use ptrdiff_t for hash table indexes, not int (which is too
15899 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15900 32-bit --with-wide-int hosts).
15902 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15903 Add a FIXME comment about memory leaks.

15911 with outlandish widths.
15912 * character.h (sanitize_tab_width): Rename from sanitize_width,
15913 now that we have two such functions. All uses changed.

15934 exceed limits imposed by XClientMessageEvent, as well as the usual
15935 ptrdiff_t and size_t limits.
15937 * keyboard.c: Overflow, signedness and related fixes.
15938 (make_lispy_movement): Use same integer type in forward decl
15939 that is used in the definition.
15940 (read_key_sequence, keyremap_step):
15941 Change bufsize argument back to int, undoing my 2011-03-30 change.
15942 We prefer signed types, and int is wide enough here.
15943 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15944 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15945 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15946 length, not size_t. Use ptrdiff_t for index, not int.
15947 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15948 possibility of integer overflow.

15972 (lookup_image): Remove unnecessary tests.
15973 (xbm_image_p): Locals are now of int, not EMACS_INT,
15974 since parse_image_check makes sure they fit into int.
15975 (png_load, gif_load, svg_load_image):
15976 Prefer int to unsigned where either will do.
15977 (tiff_handler): New function, combining the cores of the
15978 old tiff_error_handler and tiff_warning_handler.
15979 This function is rewritten to use vsnprintf and thereby avoid
15980 stack buffer overflows. It uses only the features of vsnprintf
15981 that are common to both POSIX and native Microsoft.
15982 (tiff_error_handler, tiff_warning_handler): Use it.
15983 (tiff_load, gif_load, imagemagick_load_image):
15984 Don't assume :index value fits in 'int'.
15985 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15986 (imagemagick_load_image): Check that crop parameters fit into
15987 the integer types that MagickCropImage accepts. Don't assume
15988 Vimagemagick_render_type has a nonnegative value. Don't assume
15989 size_t fits in 'long'.
15990 (gs_load): Use printmax_t to print the widest integers possible.

16000 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16001 the display spec is of the form `(space ...)'.

16003 handle_single_display_spec, not just 1 or zero.
16004 (handle_single_display_spec): If the display spec is of the form
16005 `(space ...)', and specifies display in the text area, return 2
16007 (try_cursor_movement): Check for the need to scroll more
16008 accurately, and prefer exact match for point under bidi.
16009 Don't advance `row' beyond the last row of the window.

16027 buffers, return left-to-right.
16028 (set_cursor_from_row): Consider candidate row a win if its glyph
16029 represents a newline and point is on that newline. Fixes cursor
16030 positioning on the newline at EOL of R2L text within L2R
16031 paragraph, and vice versa.
16032 (try_cursor_movement): Check continued rows, in addition to
16033 continuation rows. Fixes unwarranted scroll when point enters a
16034 continued line of R2L text within an L2R paragraph, or vice versa.
16035 (cursor_row_p): Consider the case of point being equal to
16036 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

16062 * xdisp.c (redisplay_window): When computing centering_position,
16063 account for the height of the header line. (Bug#8874)
16065 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16066 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16067 candidate is selected by the mouse, and that candidate has a
16068 composed character under the mouse.
16070 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16071 coordinates reported by pos-visible-in-window-p for a composed
16072 character in column zero.
16074 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16080 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16081 consider it a hit if to_charpos is anywhere in the range of the
16082 composed buffer positions.
16084 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16086 * image.c (gif_load): Don't assume that each subimage has the same
16087 dimensions as the base image. Handle disposal method that is
16088 "undefined" by the gif spec (Bug#9335).
16090 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16092 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16095 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16097 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16098 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16099 from an Org mode buffer to a Speedbar frame.
16101 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16102 a composition, take its buffer position from IT->cmp_it.charpos.
16103 Fixes cursor positioning at the beginning of a line that begins
16104 with a composed character.
16106 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16108 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16109 character bidirectional type, use STRONG_L instead. Fixes crashes
16110 in a buffer produced by `describe-categories'.
16112 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16113 members before the level stack, so they would be saved and
16114 restored when copying iterator state. Fixes incorrect reordering
16115 around TABs covered by display properties.
16117 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16119 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16125 Remove unnecessary aborts (Bug#9081).
16127 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16129 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16130 has no `load' handler, try opening the file locally. (Bug#9311)
16132 2011-08-16 Ken Brown <kbrown@cornell.edu>
16134 * gmalloc.c: Expand comment.

16189 * xdisp.c (move_it_in_display_line_to): Don't invoke
16190 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16191 ppos_it. Fixes vertical cursor motion when line beginning is
16192 covered by an image. (Bug#9296)
16194 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16196 * nsterm.h (ns_run_ascript): Declare.

16201 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16202 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16203 the event loop. Get status from as_status (Bug#7276).
16205 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16206 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16207 the event loop (Bug#7276).
16209 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16211 * gnutls.c (QCgnutls_bootprop_priority)

16233 (Fnetwork_interface_list): Allocate in increments of bytes instead
16234 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16235 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16237 (struct ifflag_def): notrailers is smart on OSX.
16238 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16239 Get hardware address with getifaddrs if available.

16243 * xdisp.c (iterate_out_of_display_property): xassert that
16244 IT->position is set to within IT->object's boundaries. Break from
16245 the loop as soon as EOB is reached; avoids infloops in redisplay

16247 Set IT->current to match the bidi iterator unconditionally.
16248 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16249 entry. Force push_it to save on the stack the current
16250 buffer/string position, to be restored by pop_it. Fix flags in
16251 the iterator structure wrt the object coming from a display
16252 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16253 properties. (Bug#9284)
16255 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16257 * fontset.c (fontset_get_font_group): Add proper type checks.

16296 longlines-mode. (Bug#9254)
16297 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16298 word-wrap under bidirectional display. (Bug#9224)
16300 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16301 is non-zero, even if the data buffer is NULL. Fixes a crash in
16302 vertical-motion with longlines-mode. (Bug#9254)
16304 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16306 * bidi.c <bidi_cache_total_alloc>: Now static.

16312 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16313 amount allocated this far in `bidi_cache_total_alloc'.
16314 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16315 non-zero, only free the data buffer without restoring the cache
16316 contents. All callers changed.
16318 * dispextern.h (bidi_unshelve_cache): Update prototype.
16320 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

16322 (move_it_vertically_backward, move_it_by_lines): Replace the call
16323 to xfree to an equivalent call to bidi_unshelve_cache.
16324 (move_it_in_display_line_to): Fix logic of returning
16325 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

16381 DISP_PROP_P, and pass it to compute_display_string_pos.
16382 Only handle text covered by a display string if DISP_PROP_P is returned
16383 non-zero. All callers of bidi_fetch_char changed.

16483 * xdisp.c (compute_display_string_pos): Don't use cached display
16484 string position if the buffer had its restriction changed.
16487 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16489 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16491 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16493 Integer signedness and overflow and related fixes. (Bug#9079)
16495 * bidi.c: Integer size and overflow fixes.
16496 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16497 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16498 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16499 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16500 (bidi_find_other_level_edge):
16501 Use ptrdiff_t instead of EMACS_INT where either will do.
16502 This works better on 32-bit hosts configured --with-wide-int.
16503 (bidi_cache_ensure_space): Check for size-calculation overflow.
16504 Use % rather than repeated addition, for better worst-case speed.
16505 Don't set bidi_cache_size until after xrealloc returns, because it
16507 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16508 (bidi_cache_ensure_space): Also check that the bidi cache size
16509 does not exceed that of the largest Lisp string or buffer. See Eli
16510 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16512 * alloc.c (__malloc_size_t): Remove.
16513 All uses replaced by size_t. See Andreas Schwab's note
16514 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16516 * image.c: Improve checking for integer overflow.
16517 (check_image_size): Assume that f is nonnull, since
16518 it is always nonnull in practice. This is one less thing to
16519 worry about when checking for integer overflow later.
16520 (x_check_image_size): New function, which checks for integer
16521 overflow issues inside X.
16522 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16523 This removes the need for a memory_full check.
16524 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16525 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16526 (xbm_read_bitmap_data): Change locals back to 'int', since
16527 their values must fit in 'int'.
16528 (xpm_load_image, png_load, tiff_load):
16529 Invoke x_create_x_image_and_pixmap earlier,
16530 to avoid much needless work if the image is too large.
16531 (tiff_load): Treat overly large images as if
16532 x_create_x_image_and_pixmap failed, not as malloc failures.
16533 (gs_load): Use x_check_image_size.
16535 * gtkutil.c: Omit integer casts.
16536 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16537 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16539 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16541 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16542 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16543 would wrongly return t on a 64-bit host.
16545 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16546 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16547 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16548 and therefore cause GCC to emit a bogus diagnostic in some cases.
16550 * image.c: Integer signedness and overflow and related fixes.
16551 This is not an exhaustive set of fixes, but it's time to
16552 record what I've got.
16553 (lookup_pixel_color, check_image_size): Remove redundant decls.
16554 (check_image_size): Don't assume that arbitrary EMACS_INT values
16555 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16556 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16557 (tiff_load, imagemagick_load_image):
16558 Check for overflow in size calculations.
16559 (x_create_x_image_and_pixmap): Remove unnecessary test for
16560 xmalloc returning NULL; that can't happen.
16561 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16562 (xpm_color_bucket): Use better integer hashing function.
16563 (xpm_cache_color): Don't possibly over-allocate memory.
16564 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16565 (gif_memory_source):
16566 Use ptrdiff_t, not int or size_t, to record sizes.
16567 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16568 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16569 either works, as we prefer signed integers.
16570 (tiff_read_from_memory, tiff_write_from_memory):
16571 Return tsize_t, not size_t, since that's what the TIFF API wants.
16572 (tiff_read_from_memory): Don't fail simply because the read would
16573 go past EOF; instead, return a short read.
16574 (tiff_load): Omit no-longer-needed casts.
16575 (Fimagemagick_types): Don't assume size fits into 'int'.
16577 Improve hashing quality when configured --with-wide-int.
16578 * fns.c (hash_string): New function, taken from sxhash_string.
16579 Do not discard information about ASCII character case; this
16580 discarding is no longer needed.
16581 (sxhash-string): Use it. Change sig to match it. Caller changed.
16582 * lisp.h: Declare it.
16583 * lread.c (hash_string): Remove, since we now use fns.c's version.
16584 The fns.c version returns a wider integer if --with-wide-int is
16585 specified, so this should help the quality of the hashing a bit.
16587 * emacs.c: Integer overflow minor fix.
16588 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16589 Define only if GNU_LINUX.
16590 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16592 * dispnew.c: Integer signedness and overflow fixes.
16593 Remove unnecessary forward decls, that were a maintenance hassle.
16594 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16596 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16597 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16598 (prepare_desired_row, line_draw_cost):
16599 Use int, not unsigned, where either works.
16600 (save_current_matrix, restore_current_matrix):
16601 Use ptrdiff_t, not size_t, where either works.
16602 (init_display): Check for overflow more accurately, and without
16603 relying on undefined behavior.
16605 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16606 Remove, replacing with the new symbols in lisp.h. All uses changed.
16607 * fileio.c (make_temp_name):
16608 * filelock.c (lock_file_1, lock_file):
16609 * xdisp.c (message_dolog):
16610 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16611 Use pMd etc. instead.
16612 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16613 replacing the pWIDE etc. symbols removed from editfns.c.
16615 * keyboard.h (num_input_events): Now uintmax_t.
16616 This is (very slightly) less likely to mess up due to wraparound.
16619 * buffer.c: Integer signedness fixes.
16620 (alloc_buffer_text, enlarge_buffer_text):
16621 Use ptrdiff_t rather than size_t when either will do, as we prefer
16624 * alloc.c: Integer signedness and overflow fixes.
16625 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16626 (__malloc_size_t): Default to size_t, not to int.
16627 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16628 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16629 Prefer ptrdiff_t to size_t when either would do, as we prefer
16631 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16632 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16633 Now const. Initialize with values that are in range even if char
16635 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16636 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16637 These functions do the right thing with sizes > 2**32.
16638 (check_depth): Now ptrdiff_t, not int.
16639 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16640 Adjust to new way of storing sizes. Check for size overflow bugs
16642 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16643 slightly wrong anyway, as it missed one instance of
16644 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16645 (refill_memory_reserve): Omit needless cast to size_t.
16646 (mark_object_loop_halt): Mark as externally visible.
16648 * xselect.c: Integer signedness and overflow fixes.
16649 (Fx_register_dnd_atom, x_handle_dnd_message):
16650 Use ptrdiff_t, not size_t, since we prefer signed.
16651 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16652 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16653 x_dnd_atoms_size and x_dnd_atoms_length.
16655 * doprnt.c: Prefer signed to unsigned when either works.
16657 * doprnt.c (doprnt):
16659 * xdisp.c (vmessage):
16660 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16661 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16662 prefer signed arithmetic to avoid comparison confusion.
16663 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16664 but is a bit tricky.
16666 Assume freestanding C89 headers, string.h, stdlib.h.
16667 * data.c, doprnt.c, floatfns.c, print.c:
16668 Include float.h unconditionally.
16669 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16670 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16671 * regex.c: Likewise for stddef.h, string.h.
16672 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16673 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16674 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16675 (STDC_HEADERS): Remove obsolete defines.
16676 * sysdep.c: Include limits.h unconditionally.
16678 Assume support for memcmp, memcpy, memmove, memset.
16679 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16680 * regex.c (memcmp, memcpy):
16681 Remove; we assume C89 now.
16683 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16684 (__malloc_safe_bcopy): Remove; no longer needed.
16686 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16687 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16688 well either way, and we prefer signed to unsigned.
16690 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16692 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16693 closes the connection while we're reading (bug#9182).
16695 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16697 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16698 are specified (Bug#9168).
16700 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16702 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16703 Found by GCC static checking and --with-wide-int on a 32-bit host.
16705 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16707 * xdisp.c (compute_display_string_pos): Fix logic of caching
16708 previous display string position. Initialize cached_prev_pos to
16709 -1. Fixes slow-down at the beginning of a buffer.
16711 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16713 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16714 for attrs[LFACE_FONTSET_INDEX].
16716 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16718 * xml.c (parse_region): Remove unused local
16719 that was recently introduced.
16721 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16723 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16724 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16726 * xdisp.c (move_it_in_display_line_to): Record the best matching
16727 position for TO_CHARPOS while scanning the line, and restore it on
16728 exit if none of the characters scanned was an exact match.
16729 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16730 when exact match is impossible due to invisible text, and the
16731 lines are truncated.
16733 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16735 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16738 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16740 Fix a significant slow-down of cursor motion with C-n, C-p,
16741 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16742 auto-repeat under bidi redisplay in fontified buffers.
16743 * xdisp.c (compute_stop_pos_backwards): New function.
16744 (next_element_from_buffer): Call compute_stop_pos_backwards to
16745 find a suitable prev_stop when we find ourselves before
16747 (reseat): Don't look for prev_stop, as that could mean a very long
16749 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16750 <cached_disp_overlay_modiff>: Cache for last found display string
16752 (compute_display_string_pos): Return the cached position if asked
16753 about the same buffer in the same area of character positions, and
16754 the buffer wasn't changed since the time the display string
16755 position was cached.
16757 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16759 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16760 is an integer, which is important for empty lines. (Bug#9149)
16762 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16764 * frame.c (Fmodify_frame_parameters): In tty case, update the
16765 default face if necessary (Bug#4238).
16767 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16769 * editfns.c (Fstring_to_char): No need to explain what a character
16770 is in the docstring (Bug#6576).
16772 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16774 * xml.c (parse_region): Make sure we always return a tree.
16776 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16778 * xml.c (parse_region): If a document contains only comments,
16781 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16783 * xml.c (make_dom): Return comments, too.
16785 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16788 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16789 and the surrounding thread.
16790 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16791 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16792 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16794 * s/openbsd.h (BROKEN_SIGIO): Define.
16795 * unexelf.c (unexec) [__OpenBSD__]:
16796 Don't update the .mdebug section of the Alpha COFF symbol table.
16798 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16800 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16803 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16805 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16806 This fixes some race conditions on the permissions of any newly
16809 * alloc.c (valid_pointer_p): Use pipe, not open.
16810 This fixes some permissions issues when debugging.
16812 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16813 If fchown fails to set both uid and gid, try to set just gid,
16814 as that is sometimes allowed. Adjust the file's mode to eliminate
16815 setuid or setgid bits that are inappropriate if fchown fails.
16817 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16819 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16820 to compare Lisp_Objects.
16821 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16822 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16823 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16825 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16827 * lread.c (read_integer): Unread even EOF character.
16828 (read1): Likewise. Properly record start position of symbol.
16830 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16831 symbol character follows.
16833 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16835 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16836 This works around a problem with the previous change to Fcopy_file.
16837 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16838 and without this change, GCC might complain about discarding
16839 fchown's return value.
16841 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16843 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16845 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16847 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16849 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16851 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16852 it's used from the C level.
16854 * process.c: Use the same condition for POLL_FOR_INPUT in both
16855 keyboard.c and process.c (bug#1858).
16857 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16859 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16860 (Fgnutls_boot): Use it.
16862 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16864 * doc.c (Fsubstitute_command_keys): Revert last change.
16866 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16868 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16869 quotes the next character, and doesn't affect other longer
16870 sequences (bug#8935).
16872 * lread.c (syms_of_lread): Clarify that is isn't only
16873 `eval-buffer' and `eval-defun' that's affected by
16874 `lexical-binding' (bug#8460).
16876 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16878 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16879 bidi redisplay when a line includes both an image and is truncated.
16881 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16883 Fix minor problems found by static checking.
16884 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16885 (elsz): Now a signed constant, not a size_t var. We prefer signed
16886 types to unsigned, to avoid integer comparison confusion. Without
16887 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16888 "cannot optimize loop, the loop counter may overflow", a symptom
16890 * indent.c (Fvertical_motion): Mark locals as initialized.
16891 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16893 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16895 * search.c (Fre_search_backward): Mention `case-fold-search' in
16896 all the re_search_* functions (bug#8138).
16898 * keyboard.c (Fopen_dribble_file): Document when the file is
16901 2011-07-14 Eli Zaretskii <eliz@gnu.org>
16903 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16906 Support bidi reordering of display and overlay strings.
16907 * xdisp.c (compute_display_string_pos)
16908 (compute_display_string_end): Accept additional argument STRING.
16909 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16910 (reseat_to_string): Initialize bidi_it->string.s and
16911 bidi_it->string.schars.
16912 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16913 NULL (avoids a crash in bidi_paragraph_init).
16914 Initialize itb.string.lstring.
16915 (init_iterator): Call bidi_init_it only of a valid
16916 buffer position was specified. Initialize paragraph_embedding to
16918 (reseat_to_string): Initialize the bidi iterator.
16919 (display_string): If we need to ignore text properties of
16920 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

17415 (clone_per_buffer_values): Don't assume that

17417 This isn't true in general, and it's particularly not true
17418 if Emacs is configured with --with-wide-int.
17419 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17420 New macros, used in the buffer.c change.

17456 Random fixes. E.g., (random) never returned negative values.
17457 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17458 subseconds part to the entropy, as that's a bit more random.
17459 Prefer signed to unsigned, since the signedness doesn't matter and
17460 in general we prefer signed. When given a limit, use a
17461 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17462 latter isn't right if USE_2_TAGS_FOR_INTS.
17463 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17464 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17476 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17477 This is more efficient than Ffile_directory_p and avoids a minor race.

17481 * buffer.c (Foverlay_put): Say what the return value is
17484 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17485 is a directory before asking whether to use the file name
17487 (barf_or_query_if_file_exists): Make the "File is a directory"
17488 error be more correct.
17490 * fns.c (Frequire): Remove the mention of the .gz files, since
17491 that's installation-specific, but keep the mention of

17504 Qgnutls_bootprop_verify_error (which is no longer used).
17506 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17507 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17508 Also (re)move comments that are misplaced or no longer relevant.
17510 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17512 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17571 (syms_of_keymap): Defsubr make-composed-keymap.
17572 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17609 * eval.c (struct backtrace): Simplify and port the data structure.
17610 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17611 signed bit field, as this assumption is not portable and it makes
17612 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17613 "char debug_on_exit : 1" as this is not portable either; instead,
17614 use the portable "unsigned int debug_on_exit : 1". Remove unused
17615 member evalargs. Remove obsolete comments about cc bombing out.
17617 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17797 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17799 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17801 * lread.c: Integer overflow fixes.
17802 (read_integer): Radix is now EMACS_INT, not int,
17803 to improve quality of diagnostics for out-of-range radices.
17804 Calculate buffer size correctly for out-of-range radices.
17805 (read1): Check for integer overflow in radices, and in
17806 read-circle numbers.
17807 (read_escape): Avoid int overflow.
17808 (Fload, openp, read_buffer_size, read1)
17809 (substitute_object_recurse, read_vector, read_list, map_obarray):
17810 Use ptrdiff_t, not int, for sizes.

17825 2011-06-22 Leo Liu <sdl.web@gmail.com>
17827 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17828 Move to minibuffer.el.
17830 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17832 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17833 The following patches are for when GLYPH_DEBUG && !XASSERT.
17834 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17835 * dispnew.c (flush_stdout):
17836 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17837 Mark as externally visible.
17838 * dispnew.c (check_window_matrix_pointers): Now static.
17839 * dispnew.c (window_to_frame_vpos):
17840 * xfns.c (unwind_create_frame):
17841 * xterm.c (x_check_font): Remove unused local.
17842 * scroll.c (CHECK_BOUNDS):
17843 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17844 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17845 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17846 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17847 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17849 (debug_method_add): Use va_list and vsprintf rather than relying
17850 on undefined behavior with wrong number of arguments.
17851 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17852 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17853 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17854 since we're not interested in debugging glyphs with old libraries.
17855 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17856 GCC 4.6.0's static checking.
17858 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17860 Integer overflow and signedness fixes (Bug#8873).

17869 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17870 (x_create_bitmap_from_xpm_data):
17871 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17872 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17874 * xfaces.c (load_pixmap):
17875 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17876 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17877 (.bitmaps_last, struct x_output.icon_bitmap):
17878 Use ptrdiff_t, not int, for bitmap indexes.
17879 (x_allocate_bitmap_record): Check for size overflow.
17880 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17882 Use ptrdiff_t, not int, for overlay counts.
17883 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17884 * editfns.c (overlays_around, get_pos_property):
17885 * textprop.c (get_char_property_and_overlay):
17886 * xdisp.c (next_overlay_change, note_mouse_highlight):
17887 * xfaces.c (face_at_buffer_position):
17888 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17889 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17890 (Fnext_overlay_change, Fprevious_overlay_change)
17891 (mouse_face_overlay_overlaps, Foverlays_in):
17892 Use ptrdiff_t, not int, for sizes.
17893 (overlays_at, overlays_in): Check for size-calculation overflow.
17895 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17897 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17898 (x_session_initialize): Do not assume string length fits in int.
17900 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17901 This is unlikely, but can occur if DPI is outlandish.
17903 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17904 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17906 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17907 * xrdb.c (magic_file_p, search_magic_path):
17908 Omit last arg SUFFIX; it was always 0. All callers changed.
17909 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17911 * xfont.c (xfont_match): Avoid need for strlen.
17913 * xfns.c: Don't assume strlen fits in int.
17914 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17916 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17917 not unsigned long, as we prefer signed integers. All callers changed.
17918 Detect integer overflow in repeat count.
17919 (message_dolog): Don't assume print length fits in 39 bytes.
17920 (display_mode_element): Don't assume strlen fits in int.
17922 * termcap.c: Don't assume sizes fit in int and never overflow.
17923 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17924 (gobble_line): Check for size-calculation overflow.
17926 * minibuf.c (Fread_buffer):
17927 * lread.c (intern, intern_c_string):
17928 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17929 Don't assume string length fits in int.
17931 * keyboard.c (parse_tool_bar_item):
17932 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17934 * font.c: Don't assume string length fits in int.
17935 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17936 Use ptrdiff_t, not int.
17937 (font_intern_prop): Don't assume string length fits in int.
17938 Don't assume integer property fits in fixnum.
17939 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17941 * filelock.c: Fix some buffer overrun and integer overflow issues.
17942 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17943 Reformulate so as not to need the command string.
17944 Invoke gzip -cd rather than gunzip, as it's more portable.
17945 (lock_info_type, lock_file_1, lock_file):
17946 Don't assume pid_t and time_t fit in unsigned long.
17947 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17948 (current_lock_owner): Prefer signed type for sizes.
17949 Use memcpy, not strncpy, where memcpy is what is really wanted.
17950 Don't assume (via atoi) that time_t and pid_t fit in int.
17951 Check for time_t and/or pid_t out of range, e.g., via a network share.
17952 Don't alloca where an auto var works fine.
17954 * fileio.c: Fix some integer overflow issues.
17955 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17956 Don't assume string length fits in int.
17957 (directory_file_name): Don't assume string length fits in long.
17958 (make_temp_name): Don't assume pid fits in int, or that its print
17959 length is less than 20.
17961 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17963 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17965 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17967 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17968 We prefer signed integers, even for size calculations.
17970 * emacs.c: Don't assume string length fits in 'int'.
17971 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17972 (main): Don't invoke strlen when not needed.
17974 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17975 (XD_DEBUG_MESSAGE): Don't waste a byte.
17977 * callproc.c (getenv_internal_1, getenv_internal)
17978 (Fgetenv_internal):
17979 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17981 * lread.c (invalid_syntax): Omit length argument.
17982 All uses changed. This doesn't fix a bug, but it simplifies the
17983 code away from its former Hollerith-constant appearance, and it's
17984 one less 'int' to worry about when looking at integer-overflow issues.
17985 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17987 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17988 This didn't break anything, but it didn't help either.
17989 It's confusing to put a bogus integer in a place where the actual
17990 value does not matter.
17991 (LIST_END_P): Remove unused macro and its bogus comment.
17992 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17994 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17995 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17997 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17998 We prefer signed types, and the value cannot exceed the EMACS_INT
17999 range anyway (because otherwise the length would not be representable).
18000 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18001 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18002 This avoids a GCC warning when WIDE_EMACS_INT.
18004 * indent.c (sane_tab_width): New function.
18005 (current_column, scan_for_column, Findent_to, position_indentation)
18006 (compute_motion): Use it. This is just for clarity.
18007 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18009 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18011 * lisp.h (lint_assume): New macro.
18012 * composite.c (composition_gstring_put_cache):
18013 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18015 * editfns.c, insdel.c:
18016 Omit unnecessary forward decls, to simplify future changes.
18018 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18020 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18022 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18023 Use much-faster test for byte-length change.
18024 Don't assume string byte-length fits in 'int'.
18025 Check that character arg fits in 'int'.
18026 (mapcar1): Declare byte as byte, for clarity.
18028 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18030 * fns.c (concat): Catch string overflow earlier.
18031 Do not rely on integer wraparound.
18033 * dispextern.h (struct it.overlay_strings_charpos)
18034 (struct it.selective): Now EMACS_INT, not int.
18035 * xdisp.c (forward_to_next_line_start)
18036 (back_to_previous_visible_line_start)
18037 (reseat_at_next_visible_line_start, next_element_from_buffer):
18038 Don't arbitrarily truncate the value of 'selective' to int.
18040 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18042 * composite.c: Don't truncate sizes to 'int'.
18043 (composition_gstring_p, composition_reseat_it)
18044 (composition_adjust_point): Use EMACS_INT, not int.
18045 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18046 not EMACS_UINT, for indexes.
18048 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18050 * buffer.c: Include <verify.h>.
18051 (struct sortvec.priority, struct sortstr.priority):
18052 Now EMACS_INT, not int.
18053 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18054 (struct sortstr.size, record_overlay_string)
18055 (struct sortstrlist.size, struct sortlist.used):
18056 Don't truncate size to int.
18057 (record_overlay_string): Check for size-calculation overflow.
18058 (init_buffer_once): Check at compile-time, not run-time.
18060 2011-06-22 Jim Meyering <meyering@redhat.com>
18062 Don't leak an XBM-image-sized buffer
18063 * image.c (xbm_load): Free the image buffer after using it.
18065 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18068 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18069 that Sun C diagnosed.
18070 * fns.c (secure_hash): Fix pointer signedness issue.
18071 * intervals.c (static_offset_intervals): New function.
18072 (offset_intervals): Use it.
18074 2011-06-21 Leo Liu <sdl.web@gmail.com>
18077 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18080 * fns.c (secure_hash): Rename from crypto_hash_function and change
18081 the first arg to accept symbols.
18082 (Fsecure_hash): New primitive.
18083 (syms_of_fns): New symbols.
18085 2011-06-20 Deniz Dogan <deniz@dogan.se>
18087 * process.c (Fset_process_buffer): Clarify return value in
18090 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18092 * dispnew.c (add_window_display_history): Use BVAR.
18094 * xdisp.c (debug_method_add): Use BVAR.
18095 (check_window_end, dump_glyph_matrix, dump_glyph)
18096 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18098 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18101 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18102 check till after the cache is created in init_frame_faces.
18104 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18106 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18108 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18110 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18111 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18112 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18114 Improve buffer-overflow checking (Bug#8873).
18115 * fileio.c (Finsert_file_contents):
18116 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18117 Remove the old (too-loose) buffer overflow checks.
18118 They weren't needed, since make_gap checks for buffer overflow.
18119 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18120 The old code merely checked for Emacs fixnum overflow, and relied
18121 on undefined (wraparound) behavior. The new code avoids undefined
18122 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18124 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18125 Tune. Don't use wider integers than needed. Don't use alloca.
18126 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18128 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18130 * insdel.c, lisp.h (buffer_overflow): New function.
18131 (insert_from_buffer_1, replace_range, replace_range_2):
18132 * insdel.c (make_gap_larger):
18133 * editfns.c (Finsert_char):
18134 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18136 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18138 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18140 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18142 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18143 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18145 * fileio.c: Don't assume EMACS_INT fits in off_t.
18146 (emacs_lseek): New static function.
18147 (Finsert_file_contents, Fwrite_region): Use it.
18148 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18150 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18152 * fns.c: Don't overflow int when computing a list length.
18153 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18154 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18155 truncation on 64-bit hosts. Check for QUIT every
18156 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18157 faster and is responsive enough.
18158 (Flength): Report an error instead of overflowing an integer.
18159 (Fsafe_length): Return a float if the value is not representable
18160 as a fixnum. This shouldn't happen except in contrived situations.
18161 (Fnthcdr, Fsort): Don't assume list length fits in int.
18162 (Fcopy_sequence): Don't assume vector length fits in int.
18164 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18165 (header_size, word_size): New constants.
18166 (allocate_vectorlike): Don't check size overflow here.
18167 (allocate_vector): Check it here instead, since this is the only
18168 caller of allocate_vectorlike that could cause overflow.
18169 Check that the new vector's length is representable as a fixnum.
18171 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18172 The previous code was bogus. For example, next_almost_prime (32)
18173 returned 39, which is undesirable as it is a multiple of 3; and
18174 next_almost_prime (24) returned 25, which is a multiple of 5 so
18175 why was the code bothering to check for multiples of 7?
18177 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18179 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18181 Variadic C functions now count arguments with ptrdiff_t.
18182 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18183 Back then I didn't know that the Emacs coding style prefers signed int.
18184 Also, in the meantime I found a few more instances where arguments
18185 were being counted with int, which may truncate counts on 64-bit
18186 machines, or EMACS_INT, which may be unnecessarily wide.
18187 * lisp.h (struct Lisp_Subr.function.aMANY)
18188 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18189 Arg counts are now ptrdiff_t, not size_t.
18190 All variadic functions and their callers changed accordingly.
18191 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18192 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18193 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18194 * callint.c (Fcall_interactively): Check arg count for overflow,
18195 to avoid potential buffer overrun. Use signed char, not 'int',
18196 for 'varies' array, so that we needn't bother to check its size
18197 calculation for overflow.
18198 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18199 * eval.c (apply_lambda):
18200 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18201 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18202 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18204 * callint.c (Fcall_interactively): Don't use index var as event count.
18206 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18207 * mem-limits.h (SIZE): Remove; no longer used.
18209 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18211 Remove unnecessary casts.
18212 * xterm.c (x_term_init):
18213 * xfns.c (x_set_border_pixel):
18214 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18215 These aren't needed now that we assume ANSI C.
18217 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18218 It's more likely to cause problems (due to unsigned overflow)
18221 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18223 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18225 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18227 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18229 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18231 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18233 GLYPH_CODE_FACE returns EMACS_INT, not int.
18234 * dispextern.h (merge_faces):
18235 * xfaces.c (merge_faces):
18236 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18237 Don't assume EMACS_INT fits in int.
18239 * character.h (CHAR_VALID_P): Remove unused parameter.
18240 * fontset.c, lisp.h, xdisp.c: All uses changed.
18242 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18244 * fns.c (concat): Minor tuning based on overflow analysis.
18245 This doesn't fix any bugs. Use int to hold character, instead
18246 of constantly refetching from Emacs object. Use XFASTINT, not
18247 XINT, for value known to be a character. Don't bother comparing
18248 a single byte to 0400, as it's always less.
18250 * floatfns.c (Fexpt):
18251 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18253 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18256 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18258 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18259 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18260 incorrectly succeed when S was a string, because 4294967386 was
18261 truncated before it was used.
18263 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18264 Otherwise, an out-of-range integer could cause undefined behavior
18267 * composite.c: Use int, not EMACS_INT, for characters.
18268 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18269 EMACS_INT, for values that are known to be in character range.
18270 This doesn't fix any bugs but is the usual style inside Emacs and
18271 may generate better code on 32-bit machines.
18273 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18274 This is for reasons similar to the recent CHAR_STRING fix.
18275 * charset.c (Fencode_char): Check that character arg is actually
18276 a character. Pass an int to ENCODE_CHAR.
18277 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18278 wider than 'int', as a compile-time check to prevent future regressions
18281 * character.c (char_string): Remove unnecessary casts.
18283 Make sure a 64-bit char is never passed to CHAR_STRING.
18284 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18285 by silently ignoring the top 32 bits, allowing some values
18286 that were far too large to be valid characters.
18287 * character.h: Include <verify.h>.
18288 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18289 arguments are no wider than unsigned, as a compile-time check
18290 to prevent future regressions in this area.
18292 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18293 (Fsubst_char_in_region):
18295 * xdisp.c (decode_mode_spec_coding):
18296 Adjust to CHAR_STRING's new requirement.
18297 * editfns.c (Finsert_char, Fsubst_char_in_region):
18298 * fns.c (concat): Check that character args are actually
18299 characters. Without this test, these functions did the wrong
18300 thing with wildly out-of-range values on 64-bit hosts.
18302 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18303 These casts should not be needed on 32-bit hosts, either.
18304 * keyboard.c (read_char):
18305 * lread.c (Fload): Remove casts to unsigned.
18307 * lisp.h (UNSIGNED_CMP): New macro.
18308 This fixes comparison bugs on 64-bit hosts.
18309 (ASCII_CHAR_P): Use it.
18310 * casefiddle.c (casify_object):
18311 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18312 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18313 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18314 * dispextern.h (FACE_FROM_ID):
18315 * keyboard.c (read_char): Use UNSIGNED_CMP.
18317 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18318 not to EMACS_INT, to avoid GCC warning.
18320 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18322 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18323 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18324 isn't needed on 32-bit machines.
18326 * buffer.c (Fgenerate_new_buffer_name):
18327 Use EMACS_INT for count, not int.
18328 (advance_to_char_boundary): Return EMACS_INT, not int.
18330 * data.c (Qcompiled_function): Now static.
18332 * window.c (window_body_lines): Now static.
18334 * image.c (gif_load): Rename local to avoid shadowing.
18336 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18337 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18338 * alloc.c (make_save_value): Integer argument is now of type
18339 ptrdiff_t, not int.
18340 (mark_object): Use ptrdiff_t, not int.
18341 * lisp.h (pD): New macro.
18342 * print.c (print_object): Use it.
18344 * alloc.c: Use EMACS_INT, not int, to count objects.
18345 (total_conses, total_markers, total_symbols, total_vector_size)
18346 (total_free_conses, total_free_markers, total_free_symbols)
18347 (total_free_floats, total_floats, total_free_intervals)
18348 (total_intervals, total_strings, total_free_strings):
18349 Now EMACS_INT, not int. All uses changed.
18350 (Fgarbage_collect): Compute overall total using a double, so that
18351 integer overflow is less likely to be a problem. Check for overflow
18352 when converting back to an integer.
18353 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18354 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18355 These were 'int' variables that could overflow on 64-bit hosts;
18356 they were never used, so remove them instead of repairing them.
18357 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18358 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18359 Previously, this ceilinged at INT_MAX, but that doesn't work on
18361 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18363 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18364 (allocate_vectorlike): Check for ptrdiff_t overflow.
18365 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18366 when a (possibly-narrower) signed value would do just as well.
18367 We prefer using signed arithmetic, to avoid comparison confusion.
18369 * alloc.c: Catch some string size overflows that we were missing.
18370 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18371 for convenience in STRING_BYTES_MAX.
18372 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18373 The definition here is exact; the one in lisp.h was approximate.
18374 (allocate_string_data): Check for string overflow. This catches
18375 some instances we weren't catching before. Also, it catches
18376 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18377 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18378 and ptrdiff_t and EMACS_INT are both 64 bits.
18380 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18381 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18382 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18384 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18386 * alloc.c (Fmake_string): Check for out-of-range init.
18388 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18390 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18392 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18394 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18395 xg_get_default_scrollbar_width.
18397 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18398 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18399 (style_changed_cb): Call update_theme_scrollbar_width and call
18400 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18401 all frames (Bug#8505).
18402 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18403 Call gtk_window_set_resizable if HAVE_GTK3.

18405 and height if HAVE_GTK3 (Bug#8505).
18406 (scroll_bar_width_for_theme): New variable.
18407 (update_theme_scrollbar_width): New function.
18408 (xg_get_default_scrollbar_width): Move code to
18409 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18410 (xg_initialize): Call update_theme_scrollbar_width.
18412 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18414 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18416 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18418 * frame.c (make_frame): Call other_buffer_safely instead of
18421 * window.c (temp_output_buffer_show): Call display_buffer with
18422 second argument Vtemp_buffer_show_specifiers and reset latter
18423 immediately after the call.
18424 (Vtemp_buffer_show_specifiers): New variable.
18425 (auto_window_vscroll_p, next_screen_context_lines)
18426 (Vscroll_preserve_screen_position): Remove leading asterisks from

18609 Remove static from declaration of Qdelete_window, it's
18610 temporarily needed by Fbury_buffer.
18611 (replace_window): Don't assign orig_top_line and

18990 value of a `display' property is a "replacing spec".
18991 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18992 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

19022 * gnutls.c: Use Emacs's memory allocators.
19023 Without this change, the gnutls library would invoke malloc etc.
19024 directly, which causes problems on non-SYNC_INPUT hosts, and which
19025 runs afoul of improving memory_full behavior. (Bug#8761)
19026 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19027 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19028 xfree instead of the default malloc, realloc, free.
19029 (Fgnutls_boot): No need to check for memory allocation failure,
19030 since xmalloc does that for us.

19054 * alloc.c (allocate_vectorlike):
19055 Check for overflow in vector size calculations.
19056 * ccl.c (ccl_driver):
19057 Check for overflow when converting EMACS_INT to int.

19059 need to be updated by these changes.
19060 * fns.c (make_hash_table, maybe_resize_hash_table):
19061 Check for integer overflow with large hash tables.
19062 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19063 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19064 (SXHASH_REDUCE): New macro.
19065 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19066 Use it instead of discarding useful hash info with large hash values.
19067 (sxhash_float): New function.
19068 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19069 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19070 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19071 Rewrite to use FIXNUM_BITS, as this simplifies things.
19072 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19073 Adjust signatures to match updated version of code.
19074 (consing_since_gc): Now EMACS_INT, since a single hash table can
19075 use more than INT_MAX bytes.

19098 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19100 Don't force ./temacs to start in terminal mode.
19102 * frame.c (make_initial_frame): Initialize faces in all cases, not
19103 only when CANNOT_DUMP is defined.
19104 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19106 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19108 * dispnew.c (add_window_display_history): Use const for the string
19109 pointer. Remove declaration, not needed.
19111 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19113 Use 'inline', not 'INLINE'.
19114 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19115 * alloc.c, fontset.c (INLINE): Remove.
19116 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19117 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19118 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19119 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19120 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19122 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19124 Make it possible to run ./temacs.
19126 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19127 syms_of_callproc does the same thing. Remove test for
19128 "initialized", do it in the caller.
19129 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19131 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19133 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19134 (read_minibuf): Use get_minibuffer.
19135 (syms_of_minibuf): Use DEFSYM.
19136 (Qmetadata): New var.
19137 * data.c (Qbuffer): Don't make it static.
19138 (syms_of_data): Use DEFSYM.
19140 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19142 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19143 (CCL_CODE_MIN): New macro.
19145 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19147 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19149 * eval.c (Qdebug): Now static.
19150 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19151 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19152 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19154 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19156 * image.c: Various fixes to ImageMagick code comments.
19157 (Fimagemagick_types): Doc fix.
19159 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19161 Minor fixes prompted by GCC 4.6.0 warnings.
19163 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19165 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19166 (x_clipboard_manager_save_all): Move extern decl to ...
19167 * xterm.h: ... here, so that it can be checked for consistency.
19169 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19171 * xselect.c (x_clipboard_manager_save_frame)
19172 (x_clipboard_manager_save_all): New functions.
19173 (Fx_clipboard_manager_save): Lisp function deleted.
19175 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19176 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19178 * xterm.h: Update prototype.
19180 2011-05-28 William Xu <william.xwl@gmail.com>
19182 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19183 exiting (Bug#8239).
19185 2011-05-28 Jim Meyering <meyering@redhat.com>
19187 Avoid a sign-extension bug in crypto_hash_function.
19188 * fns.c (to_uchar): Define.
19189 (crypto_hash_function): Use it to convert some newly-signed
19190 variables to unsigned, to avoid sign-extension bugs. For example,
19191 without this change, (md5 "truc") would evaluate to
19192 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19193 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19194 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19196 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19198 Integer overflow fixes.
19200 * dbusbind.c: Serial number integer overflow fixes.
19201 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19202 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19203 to hold a serial number that is too large for a fixnum.
19204 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19205 Check for serial numbers out of range. Decode any serial number
19206 that was so large that it became a float. (Bug#8722)
19208 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19209 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19210 Use XFASTINT rather than XUINT when numbers are nonnegative.
19211 (xd_append_arg, Fdbus_method_return_internal):
19212 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19213 arguments, check that Lisp number is nonnegative, rather than
19214 silently wrapping negative numbers around. (Bug#8722)
19215 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19218 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19220 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19222 ccl: Add integer overflow checks.
19223 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19224 (IN_INT_RANGE): New macros.
19225 (ccl_driver): Use them to check for integer overflow when
19226 decoding a CCL program. Many of the new checks are whether XINT (x)
19227 fits in int; it doesn't always, on 64-bit hosts. The new version
19228 doesn't catch all possible integer overflows, but it's an
19229 improvement. (Bug#8719)
19231 * alloc.c (make_event_array): Use XINT, not XUINT.
19232 There's no need for unsigned here.
19234 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19235 This follows up to the 2011-05-06 change that substituted uintptr_t
19236 for EMACS_INT. This case wasn't caught back then.
19238 Rework Fformat to avoid integer overflow issues.
19239 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19240 now (part of C89). Include <verify.h>.
19241 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19242 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19243 (Fformat): Avoid the prepass trying to compute sizes; it was only
19244 approximate and thus did not catch overflow reliably. Instead, walk
19245 through the format just once, formatting and computing sizes as we go,
19246 checking for integer overflow at every step, and allocating a larger
19247 buffer as needed. Keep track separately whether the format is
19248 multibyte. Keep only the most-recently calculated precision, rather
19249 than them all. Record whether each argument has been converted to
19250 string. Use EMACS_INT, not int, for byte and char and arg counts.
19251 Support field widths and precisions larger than INT_MAX. Avoid
19252 sprintf's undefined behavior with conversion specifications such as %#d
19253 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19254 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19255 formatting out-of-range floating point numbers with int
19256 formats. (Bug#8668)
19258 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19260 * data.c: Avoid integer truncation in expressions involving floats.
19261 * data.c: Include <intprops.h>.
19262 (arith_driver): When there's an integer overflow in an expression
19263 involving floating point, convert the integers to floating point
19264 so that the resulting value does not suffer from catastrophic
19265 integer truncation. For example, on a 64-bit host (* 4
19266 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19267 Do not rely on undefined behavior after integer overflow.
19269 merge count_size_as_multibyte, parse_str_to_multibyte
19270 * character.c, character.h (count_size_as_multibyte):
19271 Rename from parse_str_to_multibyte; all uses changed.
19272 Check for integer overflow.
19273 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19274 since it's now a duplicate of the other. This is more of
19275 a character than a buffer op, so better that it's in character.c.
19276 * fns.c, print.c: Adjust to above changes.
19278 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19280 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19282 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19284 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19285 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19286 (x_clipboard_manager_save): Now static.
19287 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19289 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19290 (crypto_hash_function): Now static.
19291 Fix pointer signedness problems. Avoid unnecessary initializations.
19293 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19295 * termhooks.h (Vselection_alist): Make it terminal-local.
19297 * terminal.c (create_terminal): Initialize it.
19299 * xselect.c: Support for clipboard managers.
19300 (Vselection_alist): Move to termhooks.h as terminal-local var.
19301 (LOCAL_SELECTION): New macro.
19302 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19303 (symbol_to_x_atom): Remove gratuitous arg.
19304 (x_handle_selection_request, lisp_data_to_selection_data)
19305 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19306 (x_own_selection, x_get_local_selection, x_convert_selection):
19307 New arg, specifying work frame. Use terminal-local Vselection_alist.
19308 (some_frame_on_display): Delete unused function.
19309 (Fx_own_selection_internal, Fx_get_selection_internal)
19310 (Fx_disown_selection_internal, Fx_selection_owner_p)
19311 (Fx_selection_exists_p): New optional frame arg.
19312 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19313 (x_handle_selection_clear): Don't treat other terminals with the
19314 same keyboard specially. Use the terminal-local Vselection_alist.
19315 (x_clear_frame_selections): Use Frun_hook_with_args.
19317 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19319 * xterm.h: Add support for those atoms.
19321 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19323 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19324 (converted_selections, conversion_fail_tag): New global variables.
19325 (x_selection_request_lisp_error): Free the above.
19326 (x_get_local_selection): Remove unnecessary code.
19327 (x_reply_selection_request): Args changed; handle arbitrary array
19328 of converted selections stored in converted_selections.
19329 Separate the XChangeProperty and SelectionNotify steps.
19330 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19331 (x_convert_selection): New function.
19332 (x_handle_selection_event): Simplify.
19333 (x_get_foreign_selection): Don't ignore incoming requests while
19334 waiting for an answer; this will fail when we implement
19335 SAVE_TARGETS, and seems unnecessary anyway.
19336 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19337 (Vx_sent_selection_functions): Doc fix.
19339 2011-05-26 Leo Liu <sdl.web@gmail.com>
19341 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19343 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19345 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19347 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19348 for fringe update if it has periodic bitmap.
19349 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19350 and fringe_bitmap_periodic_p.
19352 * fringe.c (get_fringe_bitmap_data): New function.
19353 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19354 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19355 row. Mark glyph row for fringe update if periodicity changed.
19357 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19358 for fringe update unless it has periodic bitmap.
19360 2011-05-25 Kenichi Handa <handa@m17n.org>
19362 * xdisp.c (get_next_display_element): Set correct it->face_id for
19363 a static composition.
19365 2011-05-24 Leo Liu <sdl.web@gmail.com>
19368 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19370 * fns.c (crypto_hash_function, Fsha1): New function.
19371 (Fmd5): Use crypto_hash_function.
19372 (syms_of_fns): Add Ssha1.
19374 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19376 * gnutls.c: Remove unused macros.
19377 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19378 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19379 Remove macros that are defined and never used.
19380 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19382 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19384 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19385 (Fx_get_selection_internal): Minor cleanup.
19386 (Fx_own_selection_internal): Rename arguments for consistency with
19389 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19391 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19393 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19395 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19397 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19399 * dispnew.c (scrolling_window): Don't exclude the case that the
19400 last enabled row in the desired matrix touches the bottom boundary.
19402 2011-05-21 Glenn Morris <rgm@gnu.org>
19404 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19405 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19406 and add some more files.
19408 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19410 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19411 report_file_error introduced by the change from 2011-05-07.
19413 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19415 * systime.h (Time): Define only if emacs is defined.
19416 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19417 where the include path doesn't have X11/X.h by default. See
19418 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19420 2011-05-20 Kenichi Handa <handa@m17n.org>
19422 * composite.c (find_automatic_composition): Fix previous change.
19424 2011-05-20 Glenn Morris <rgm@gnu.org>
19426 * lisp.mk: New file, split from Makefile.in.
19427 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19428 (shortlisp): Remove.
19429 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19431 2011-05-19 Glenn Morris <rgm@gnu.org>
19433 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19434 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19435 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19436 (lisp): Set the order to that of loadup.el.
19437 (shortlisp): Make it a copy of $lisp.
19438 (SOME_MACHINE_LISP): Remove.
19439 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19440 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19442 2011-05-18 Kenichi Handa <handa@m17n.org>
19444 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19445 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19446 (find_automatic_composition): Mostly rewrite for efficiency.
19448 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19450 * makefile.w32-in: Update dependencies.
19452 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19454 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19455 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19457 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19459 Fix some integer overflow issues, such as string length overflow.
19461 * insdel.c (count_size_as_multibyte): Check for string overflow.
19463 * character.c (lisp_string_width): Check for string overflow.
19464 Use EMACS_INT, not int, for string indexes and lengths; in
19465 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19466 the resulting string length overflows an EMACS_INT; instead,
19467 report a string overflow if no precision given. When checking for
19468 precision exhaustion, use a check that cannot possibly have
19469 integer overflow. (Bug#8675)
19470 * character.h (lisp_string_width): Adjust to new signature.
19472 * alloc.c (string_overflow): New function.
19473 (Fmake_string): Use it. This doesn't change behavior, but saves
19474 a few bytes and will simplify future changes.
19475 * character.c (string_escape_byte8): Likewise.
19476 * lisp.h (string_overflow): New decl.
19478 Fixups, following up to the user-interface timestamp change.
19479 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19480 for UI timestamps, instead of unsigned long.
19481 * msdos.c (mouse_get_pos): Likewise.
19482 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19483 * w32gui.h (Time): Define by including "systime.h" rather than by
19484 declaring it ourselves. (Bug#8664)
19486 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19487 * image.c (clear_image_cache): Likewise.
19489 * term.c (term_mouse_position): Don't assume time_t wraparound.
19491 Be more systematic about user-interface timestamps.
19492 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19493 and sometimes 'EMACS_UINT', to represent these timestamps.
19494 This change causes it to use 'Time' uniformly, as that's what X uses.
19495 This makes the code easier to follow, and makes it easier to catch
19496 integer overflow bugs such as Bug#8664.
19497 * frame.c (Fmouse_position, Fmouse_pixel_position):
19498 Use Time, not unsigned long, for user-interface timestamps.
19499 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19500 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19501 * keyboard.h (last_event_timestamp): Likewise.
19502 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19503 * menu.h (xmenu_show): Likewise.
19504 * term.c (term_mouse_position): Likewise.
19505 * termhooks.h (struct input_event.timestamp): Likewise.
19506 (struct terminal.mouse_position_hook): Likewise.
19507 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19508 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19509 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19510 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19511 what it was before.
19512 * menu.h, termhooks.h: Include "systime.h", for Time.
19514 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19515 Don't assume that the difference between two unsigned long values
19516 can fit into an integer. At this point, we know button_down_time
19517 <= event->timestamp, so the difference must be nonnegative, so
19518 there's no need to cast the result if double-click-time is
19519 nonnegative, as it should be; check that it's nonnegative, just in
19520 case. This bug is triggered when events are more than 2**31 ms
19521 apart (about 25 days). (Bug#8664)
19523 * xselect.c (last_event_timestamp): Remove duplicate decl.
19524 (x_own_selection): Remove needless cast to unsigned long.
19526 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19527 that always fit in int. Use a sentinel instead of a counter, to
19528 avoid a temp and to allay GCC's concerns about possible int overflow.
19529 * frame.h (struct frame): Use int for menu_bar_items_used
19530 instead of EMACS_INT, since it always fits in int.
19532 * menu.c (grow_menu_items): Check for int overflow.
19534 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19536 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19537 Before, the code was not consistent. These values cannot exceed
19538 2**31 - 1 so there's no need to make them unsigned.
19539 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19540 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19541 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19543 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19545 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19546 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19547 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19548 presumably because the widths might not match.
19550 * window.c (size_window): Avoid needless test at loop start.
19552 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19554 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19556 2011-05-12 Drew Adams <drew.adams@oracle.com>
19558 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19560 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19562 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19563 `width' to `bar_area_x' and `bar_area_width', respectively.
19564 (x_scroll_run): Take account of fringe background extension.
19566 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19567 Rename local vars `left' and `width' to `bar_area_x' and
19568 `bar_area_width', respectively.
19569 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19570 background extension.
19572 2011-05-10 Jim Meyering <meyering@redhat.com>
19574 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19576 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19578 * image.c (Finit_image_library): Return t for built-in image types,
19579 like pbm and xbm. (Bug#8640)
19581 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19583 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19585 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19587 * w32console.c (Fset_screen_color): Doc fix.
19588 (Fget_screen_color): New function.
19589 (syms_of_ntterm): Defsubr it.
19591 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19592 unlink the temporary file if Fcall_process didn't create it in the
19594 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19595 child process will be redirected to a file specified with `:file'.
19596 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19597 cue to call_process_cleanup not to close that handle.
19599 2011-05-07 Ben Key <bkey76@gmail.com>
19601 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19602 one of two shell specific rules, either bootstrap-temacs-CMD or
19603 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19604 to the previous implementation of the bootstrap-temacs rule.
19605 The bootstrap-temacs-CMD rule is similar to the previous
19606 implementation of the bootstrap-temacs rule except that it
19607 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19610 These changes, along with some changes to nt/configure.bat,
19611 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19612 earlier fix to add support for --cflags and --ldflags options
19613 that include quotes so that it works whether make uses cmd or
19616 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19618 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19619 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19621 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19622 a string. Handle both cases.
19623 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19624 (Fdbus_register_method): Use Qinvalid_function.
19626 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19628 * makefile.w32-in: Update dependencies.
19629 (LISP_H): Add inttypes.h and stdin.h.
19630 (PROCESS_H): Add unistd.h.
19632 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19634 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19635 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19637 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19639 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19641 * term.c (vfatal): Remove stray call to va_end.
19642 It's not needed and the C Standard doesn't allow it here anyway.
19644 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19645 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19647 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19650 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19652 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19654 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19656 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19658 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19660 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19661 * charset.c (Fdefine_charset_internal): Don't initialize
19662 charset.code_space[15]. The value was garbage, on hosts with
19663 32-bit int (Bug#8600).
19665 * lread.c (read_integer): Be more consistent with string-to-number.
19666 Use string_to_number to do the actual conversion; this avoids
19667 rounding errors and fixes some other screwups. Without this fix,
19668 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19669 (digit_to_number): Move earlier, for benefit of read_integer.
19670 Return -1 if the digit is out of range for the base, -2 if it is
19671 not a digit in any supported base. (Bug#8602)
19673 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19675 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19676 to match comment at start of function. This also removes a
19677 GCC warning about overflow in a 32+64-bit port.
19679 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19681 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19682 Reported by Stefan Monnier in
19683 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19684 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19685 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19687 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19688 (EMACS_UINTPTR): Likewise, with uintptr_t.
19690 * lisp.h: Prefer 64-bit EMACS_INT if available.
19691 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19692 on 32-bit hosts that have 64-bit int, so that they can access
19694 However, temporarily disable this change unless the temporary
19695 symbol WIDE_EMACS_INT is defined.
19697 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19699 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19700 This removes an assumption that EMACS_INT and long are the same
19701 width as pointers. The assumption is true for Emacs porting targets
19702 now, but we want to make other targets possible.
19703 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19704 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19705 In the rest of the code, change types of integers that hold casted
19706 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19707 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19708 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19709 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19710 No need to cast type when ORing.
19711 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19712 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19713 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19714 assume EMACS_INT is the same width as char *.
19715 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19716 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19717 Remove no-longer-needed casts.
19718 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19719 (xg_tool_bar_help_callback, xg_make_tool_item):
19720 Use EMACS_INTPTR to hold an integer
19721 that will be cast to void *; this can avoid a GCC warning
19722 if EMACS_INT is not the same width as void *.
19723 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19724 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19725 (current_message_1, set_message_1):
19726 Use a local to convert to proper width without a cast.
19727 * xmenu.c (dialog_selection_callback): Likewise.
19729 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19730 Also, don't assume VALBITS / RAND_BITS is less than 5,
19731 and don't rely on undefined behavior when shifting a 1 left into
19733 * lisp.h (get_random): Change signature to match.
19735 * lread.c (hash_string): Use size_t, not int, for hash computation.
19736 Normally we prefer signed values; but hashing is special, because
19737 it's better to use unsigned division on hash table sizes so that
19738 the remainder is nonnegative. Also, size_t is the natural width
19739 for hashing into memory. The previous code used 'int', which doesn't
19740 retain enough info to hash well into very large tables.
19741 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19743 * dbusbind.c: Don't possibly lose pointer info when converting.
19744 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19745 Use XPNTR rather than XHASH, so that the high-order bits of
19746 the pointer aren't lost when converting through void *.
19748 * eval.c (Fautoload): Don't double-shift a pointer.
19750 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19752 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19754 * gnutls.c (DEF_GNUTLS_FN):
19755 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19757 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19759 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19762 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19764 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19765 New version that can reserve upto 2GB of heap space.
19767 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19769 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19771 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19773 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19774 `gnutls_certificate_set_x509_key_file'.
19776 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19778 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19779 Update dependencies.
19781 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19783 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19784 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19785 Remove unused parameter `fildes'.
19786 * process.c (read_process_output, send_process): Don't pass it.
19788 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19790 Fix previous change: the library cache is defined in w32.c.
19791 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19792 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19794 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19796 Implement dynamic loading of GnuTLS on Windows.
19798 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19799 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19800 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19803 * gnutls.c (Qgnutls_dll): Define.
19804 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19805 (gnutls_*): Declare function pointers.
19806 (init_gnutls_functions): New function to initialize function pointers.
19807 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19808 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19809 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19810 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19811 (emacs_gnutls_write, emacs_gnutls_read)
19812 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19813 (Fgnutls_available_p): New function.
19814 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19815 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19816 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19818 * image.c: Include w32.h.
19819 (Vimage_type_cache): Delete.
19820 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19821 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19822 (w32_delayed_load): Move to w32.c.
19824 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19826 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19827 (w32_delayed_load): Move from image.c. When loading a library, record
19828 its filename in the :loaded-from property of the library id.
19829 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19830 Initialize and staticpro them.
19831 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19833 * process.c: Include lisp.h before w32.h, not after.
19834 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19835 instead of gnutls_record_check_pending.
19837 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19839 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19841 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19842 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19845 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19847 * xterm.c (x_set_frame_alpha): Do not set property on anything
19848 else than FRAME_X_OUTER_WINDOW (Bug#8608).

19866 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19868 * callproc.c: Indentation fixup.
19870 * sysdep.c (wait_for_termination_1): Make static.
19871 (wait_for_termination, interruptible_wait_for_termination):
19872 Move after wait_for_termination_1.
19874 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19876 * sysdep.c (interruptible_wait_for_termination): New function
19877 which is like wait_for_termination, but allows keyboard
19880 * callproc.c (Fcall_process): Add (:file "file") as an option for
19882 (Fcall_process_region): Ditto.
19884 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19886 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19887 rather than `XVECTOR (FOO)->size'.
19889 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19890 inttypes.h, as a gnulib replacement is used if it not available in
19893 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19895 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19896 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19897 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19899 * coding.c (coding_alloc_by_realloc): Error out if destination
19900 will grow beyond MOST_POSITIVE_FIXNUM.
19901 (decode_coding_emacs_mule): Abort if there isn't enough place in
19902 charbuf for the composition carryover bytes. Reserve an extra

19911 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19912 %llo or %llx format is passed. (Bug#8545)
19914 * window.c (window_scroll_line_based): Use a marker instead of
19915 simple variables to record original value of point. (Bug#7952)
19917 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19918 produced by %s or %c overflows available buffer space. (Bug#8545)
19920 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19922 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19923 (SIZE_MAX): Move defn after all includes, as they might #define it.
19925 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19927 * w32.c (init_environment): Warn about defaulting HOME to C:\.

19947 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19949 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19951 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19953 * makefile.w32-in: Update dependencies.
19955 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19957 Improve `doprnt' and its usage. (Bug#8545)
19958 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19959 `format_end'. Remove support for %l as a conversion specifier.
19960 Don't use xrealloc. Improve diagnostics when the %l size modifier
19961 is used. Update the commentary.
19963 * eval.c (verror): Simplify calculation of size_t.
19965 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19968 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19970 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19973 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19975 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19976 This makes this file independent of the recent pseudovector change.
19978 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19980 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19982 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19983 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19984 Remove unused local.
19985 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19987 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19988 GCC 4.6.0 optimizes based on type-based alias analysis.
19989 For example, if b is of type struct buffer * and v of type struct
19990 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19991 != &v->size, and therefore "v->size = 1; b->size = 2; return
19992 v->size;" must therefore return 1. This assumption is incorrect
19993 for Emacs, since it type-puns struct Lisp_Vector * with many other
19994 types. To fix this problem, this patch adds a new type struct
19995 vectorlike_header that documents the constraints on layout of vectors
19996 and pseudovectors, and helps optimizing compilers not get fooled
19997 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19998 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19999 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20001 (XSETPVECTYPE): Rewrite in terms of new macro.
20002 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20003 This is a bit clearer, and further avoids the possibility of
20004 undesirable aliasing.
20005 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20006 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20007 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20008 since Lisp_Subr is a special case (no "next" field).
20009 (ASIZE): Now uses header.size rather than size.
20010 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20011 to avoid the hassle of writing XVECTOR (foo)->header.size.
20012 (struct vectorlike_header): New type.
20013 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20014 object, to help avoid aliasing.
20015 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20016 (SUBRP): Likewise, since Lisp_Subr is a special case.
20017 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20018 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20019 (struct Lisp_Hash_Table): Combine first two members into a single
20020 struct vectorlike_header member. All uses of "size" and "next" members
20021 changed to be "header.size" and "header.next".
20022 * buffer.h (struct buffer): Likewise.
20023 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20024 * frame.h (struct frame): Likewise.
20025 * process.h (struct Lisp_Process): Likewise.
20026 * termhooks.h (struct terminal): Likewise.
20027 * window.c (struct save_window_data, struct saved_window): Likewise.
20028 * window.h (struct window): Likewise.
20029 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20030 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20031 * buffer.c (init_buffer_once): Likewise.
20032 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20034 * process.c (Fformat_network_address): Use local var for size,
20037 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20039 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20040 * data.c (atof): Remove decl; no longer used or needed.
20041 (digit_to_number): Move to lread.c.
20042 (Fstring_to_number): Use new string_to_number function, to be
20043 consistent with how the Lisp reader treats infinities and NaNs.
20044 Do not assume that floating-point numbers represent EMACS_INT
20045 without losing information; this is not true on most 64-bit hosts.
20046 Avoid double-rounding errors, by insisting on integers when
20047 parsing non-base-10 numbers, as the documentation specifies.
20048 * lisp.h (string_to_number): New decl, replacing ...
20049 (isfloat_string): Remove.
20050 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20051 (read1): Do not accept +. and -. as integers; this
20052 appears to have been a coding error. Similarly, do not accept
20053 strings like +-1e0 as floating point numbers. Do not report
20054 overflow for integer overflows unless the base is not 10 which
20055 means we have no simple and reliable way to continue.
20056 Break out the floating-point parsing into a new
20057 function string_to_number, so that Fstring_to_number parses
20058 floating point numbers consistently with the Lisp reader.
20059 (digit_to_number): Move here from data.c. Make it static inline.
20060 (E_CHAR, EXP_INT): Remove, replacing with ...
20061 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20062 (string_to_number): New function, replacing isfloat_string.
20063 This function checks for valid syntax and produces the resulting
20064 Lisp float number too. Rework it so that string-to-number
20065 no longer mishandles examples like "1.0e+". Use strtoumax,
20066 so that overflow for non-base-10 numbers is reported only when
20067 there's no portable and simple way to convert to floating point.
20069 * textprop.c (set_text_properties_1): Rewrite for clarity,
20070 and to avoid GCC warning about integer overflow.
20072 * intervals.h (struct interval): Use EMACS_INT for members
20073 where EMACS_UINT might cause problems. See
20074 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20075 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20076 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20078 (offset_intervals): Tell GCC not to worry about length overflow
20079 when negating a negative length.
20081 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20082 (overrun_check_free): Likewise.
20084 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20085 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20088 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20089 (gnutls_make_error): Rename local to avoid shadowing.
20090 (gnutls_emacs_global_deinit): ifdef out; not used.
20091 (Fgnutls_boot): Use const for pointer to readonly storage.
20092 Comment out unused local. Fix pointer signedness problems.
20094 * lread.c (openp): Don't stuff size_t into an 'int'.
20095 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20096 about possible signed overflow.
20098 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20099 (GDK_KEY_g): Don't define if already defined.
20100 (xg_prepare_tooltip): Avoid pointer signedness problem.
20101 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20103 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20104 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20106 * xfns.c (Fx_window_property): Simplify a bit,
20107 to make a bit faster and to avoid GCC 4.6.0 warning.
20108 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20110 * fns.c (internal_equal): Don't assume size_t fits in int.
20112 * alloc.c (compact_small_strings): Tighten assertion a little.
20114 Replace pEd with more-general pI, and fix some printf arg casts.
20115 * lisp.h (pI): New macro, generalizing old pEd macro to other
20116 conversion specifiers. For example, use "...%"pI"d..." rather
20117 than "...%"pEd"...".
20118 (pEd): Remove. All uses replaced with similar uses of pI.
20119 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20120 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20121 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20122 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20123 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20124 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20125 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20127 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20128 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20129 * print.c (safe_debug_print, print_object): Likewise.
20130 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20132 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20133 avoiding the 0 flag, which is not portable.
20134 * process.c (Fmake_network_process): Use pI to avoid cast.
20135 * region-cache.c (pp_cache): Likewise.
20136 * xdisp.c (decode_mode_spec): Likewise.
20137 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20138 behavior on 64-bit hosts with printf arg.
20139 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20140 (x_stop_queuing_selection_requests): Likewise.
20141 (x_get_window_property): Don't truncate byte count to an 'int'
20144 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20145 here, since it parses constructs like leading '-' and spaces,
20146 which are not wanted; and it overflows with large numbers.
20147 Instead, simply match F[0-9]+, which is what is wanted anyway.
20149 * alloc.c: Remove unportable assumptions about struct layout.
20150 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20151 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20152 (allocate_vectorlike, make_pure_vector): Use the new macros,
20153 plus offsetof, to remove unportable assumptions about struct layout.
20154 These assumptions hold on all porting targets that I know of, but
20155 they are not guaranteed, they're easy to remove, and removing them
20156 makes further changes easier.
20158 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20159 This doesn't fix a bug but makes the code clearer.
20160 (string_overrun_cookie): Now const. Use initializers that
20161 don't formally overflow signed char, to avoid warnings.
20162 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20163 can cause Emacs to crash when string overrun checking is enabled.
20164 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20165 multiple of sizeof (EMACS_INT); it need not be, if
20166 alignof(EMACS_INT) < sizeof (EMACS_INT).
20167 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20169 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20176 supposed to be handshaking. (Bug#8556)
20177 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20179 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

20189 * alloc.c (check_sblock, check_string_bytes)
20190 (check_string_free_list): Convert to standard C.
20192 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20194 * w32.c (emacs_gnutls_push): Fix typo.
20196 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20198 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20199 "cast to pointer from integer of different size".
20201 Improve doprnt and its use in verror. (Bug#8545)
20202 * doprnt.c (doprnt): Document the set of format control sequences
20203 supported by the function. Use SAFE_ALLOCA instead of always
20206 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20207 is one byte too soon. Don't use xrealloc; instead xfree and
20210 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20212 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20215 * gnutls.c: Renamed global_initialized to
20216 gnutls_global_initialized. Added internals for the
20217 :verify-hostname-error, :verify-error, and :verify-flags
20218 parameters of `gnutls-boot' and documented those parameters in the
20219 docstring. Start callback support.
20220 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20221 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20222 on error. Return error code.
20223 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20224 (emacs_gnutls_read): Likewise.
20225 (Fgnutls_boot): Return handshake error code.
20226 (emacs_gnutls_handle_error): New function.
20227 (wsaerror_to_errno): Likewise.

20289 <char-direction-table>: Deleted.
20291 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20293 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
20294 * doprnt.c: Include limits.h.
20295 (SIZE_MAX): New macro.
20296 (doprnt): Return a size_t value. 2nd arg is now size_t.
20297 Many local variables are now size_t instead of int or unsigned.
20298 Improve overflow protection. Support `l' modifier for integer
20299 conversions. Support %l conversion. Don't assume an EMACS_INT
20300 argument for integer conversions and for %c.
20302 * lisp.h (doprnt): Restore prototype.
20304 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
20305 $(SRC)/character.h.
20307 * Makefile.in (base_obj): Add back doprnt.o.
20309 * deps.mk (doprnt.o): Add back prerequisites.
20310 (callint.o): Depend on character.h.
20312 * eval.c (internal_lisp_condition_case): Include the handler
20313 representation in the error message.
20314 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
20315 when breaking from the loop.
20317 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
20319 * callint.c (Fcall_interactively): When displaying error message
20320 about invalid control letter, pass the character's codepoint, not
20321 a pointer to its multibyte form. Improve display of the character
20322 in octal and display also its hex code.
20324 * character.c (char_string): Use %x to display the (unsigned)
20325 codepoint of an invalid character, to avoid displaying a bogus
20328 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20329 `error', not SYMBOL_NAME itself.
20331 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20332 character arguments to `error'.
20334 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20335 to `error' in error message about FINAL_CHAR argument. Make sure
20336 FINAL_CHAR is a character, and use %c when it is passed as
20337 argument to `error'.

20401 Define only if needed.
20403 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
20404 by pacifying GCC about it. Maybe it's time to retire it?
20405 * xfaces.c (USG, __TIMEVAL__): Likewise.
20407 * dispextern.h (struct redisplay_interface): Rename param
20408 to avoid shadowing.
20409 * termhooks.h (struct terminal): Likewise.
20410 * xterm.c (xembed_send_message): Likewise.
20412 * insdel.c (make_gap_smaller): Define only if

20550 * process.c (send_process): Adjust to the new signatures of
20551 emacs_write and emacs_gnutls_write. Do not attempt to store

20872 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
20873 * ccl.c (Vccl_program_table): Now static.
20874 (check_ccl_update): Remove; unused.
20876 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
20877 * category.h: ... from here.
20878 * category.c (check_category_table, set_category_set): Now static.
20880 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
20881 * lisp.h: Remove these decls.
20883 * buffer.c (buffer_count): Remove unused var.
20885 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20886 so that it's not optimized away.
20887 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20888 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20889 exported only to the debugger.
20891 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20892 * atimer.h (run_all_atimers): Remove; not exported.
20894 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20895 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20896 was inaccessible from Lisp.
20897 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20898 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20900 alloc.c: Import and export fewer symbols, and remove unused items.
20901 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20903 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20904 it's not optimized away by whole-program optimization.
20905 (message_enable_multibyte, free_misc): Remove.
20906 (catchlist, handlerlist, mark_backtrace):
20907 Declare only if BYTE_MARK_STACK.
20908 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
20909 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
20910 (message_enable_multibyte): Remove decl.
20911 (free_misc, interval_free_list, float_block, float_block_index):
20912 (n_float_blocks, float_free_list, cons_block, cons_block_index):
20913 (cons_free_list, last_marked_index):
20915 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
20916 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20917 (mark_backtrace): Define only if BYTE_MARK_STACK.
20918 * xdisp.c (message_enable_multibyte): Now static.
20920 Declare Lisp_Object Q* variables to be 'static' if not exported.
20921 This makes it easier for human readers (and static analyzers)
20922 to see whether these variables are used from other modules.
20923 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20924 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20925 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

20928 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
20929 * xmenu.c, xselect.c:
20930 Declare Q* vars static if they are not used in other modules.
20931 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
20932 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
20933 Remove decls of unexported vars.
20934 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20936 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20938 Make Emacs functions such as Fatom 'static' by default.
20939 This makes it easier for human readers (and static analyzers)
20940 to see whether these functions can be called from other modules.
20941 DEFUN now defines a static function. To make the function external
20942 so that it can be used in other C modules, use the new macro DEFUE.
20943 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20944 (Finit_image_library):
20945 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20946 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20947 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20948 Remove decls, since these functions are now static.
20949 (Funintern, Fget_internal_run_time): New decls, since these functions
20950 were already external.
20952 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20953 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20959 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20960 Mark functions with DEFUE instead of DEFUN,
20961 if they are used in other modules.
20962 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20963 decls for now-static functions.
20964 * buffer.h (Fdelete_overlay): Remove decl.
20965 * callproc.c (Fgetenv_internal): Mark as internal.
20966 * composite.c (Fremove_list_of_text_properties): Remove decl.

20970 * doc.c (Fdocumntation_property): New forward static decl.
20971 * eval.c (Ffetch_bytecode): New forward static decl.
20972 (Funintern): Remove extern decl; now in .h file where it belongs.
20973 * fileio.c (Fmake_symbolic_link): New forward static decl.
20974 * image.c (Finit_image_library): New forward static decl.
20975 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20976 * intervals.h (Fprevious_property_change):
20977 (Fremove_list_of_text_properties): Remove decls.
20978 * keyboard.c (Fthis_command_keys): Remove decl.
20979 (Fcommand_execute): New forward static decl.
20980 * keymap.c (Flookup_key): New forward static decl.
20981 (Fcopy_keymap): Now static.
20982 * keymap.h (Flookup_key): Remove decl.
20983 * process.c (Fget_process): New forward static decl.
20984 (Fprocess_datagram_address): Mark as internal.

20995 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
20997 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21000 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21002 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21003 when at ZV. (Bug#8487)
21005 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21007 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21009 * keyboard.c (parse_tool_bar_item): Likewise.
21010 * sound.c (sound_cleanup, alsa_close): Likewise.
21011 * termcap.c (tgetent): Likewise.
21012 * xfns.c (x_default_font_parameter): Likewise.
21013 * xsettings.c (read_and_apply_settings): Likewise.
21015 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21016 (overrun_check_free): Protoize.
21018 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21020 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21021 since callers should never pass a negative size.
21022 Change the signature to match that of plain 'read' and 'write'; see
21023 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21024 * lisp.h: Update prototypes of emacs_write and emacs_read.
21026 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21028 * xdisp.c (redisplay_window): Don't try to determine the character
21029 position of the scroll margin if the window start point w->startp
21030 is outside the buffer's accessible region. (Bug#8468)
21032 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21034 Fix write-region and its subroutines for buffers > 2GB.
21035 * fileio.c (a_write, e_write): Modify declaration of arguments and
21036 local variables to support buffers larger than 2GB.
21037 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21039 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21040 argument, local variables, and return value.
21042 * lisp.h: Update prototypes of emacs_write and emacs_read.
21044 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21046 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21048 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21050 Fix more problems found by GCC 4.6.0's static checks.
21052 * xdisp.c (vmessage): Use a better test for character truncation.
21054 * charset.c (load_charset_map): <, not <=, for optimization,
21055 and to avoid potential problems with integer overflow.
21056 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21057 * casetab.c (set_identity, shuffle): Likewise.
21058 * editfns.c (Fformat): Likewise.
21059 * syntax.c (skip_chars): Likewise.
21061 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21062 This also lets GCC 4.6.0 generate slightly better loop code.
21064 * callint.c (Fcall_interactively): <, not <=, for optimization.
21065 (Fcall_interactively): Count the number of arguments produced,
21066 not the number of arguments given. This is simpler and lets GCC
21067 4.6.0 generate slightly better code.
21069 * ftfont.c: Distingish more carefully between FcChar8 and char.
21070 The previous code passed unsigned char * to a functions like
21071 strlen and xstrcasecmp that expect char *, which does not
21072 conform to the C standard.
21073 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21074 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21075 char * when the C standard requires it.
21077 * keyboard.c (read_char): Remove unused var.
21079 * eval.c: Port to Windows vsnprintf (Bug#8435).
21080 Include <limits.h>.
21081 (SIZE_MAX): Define if the headers do not.
21082 (verror): Do not give up if vsnprintf returns a negative count.
21083 Instead, grow the buffer. This ports to Windows vsnprintf, which
21084 does not conform to C99. Problem reported by Eli Zaretskii.
21085 Also, simplify the allocation scheme, by avoiding the need for
21086 calling realloc, and removing the ALLOCATED variable.
21088 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21090 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21091 But keep the doprint source code for now, as we might revamp it
21092 and use it again (Bug#8435).
21093 * lisp.h (doprnt): Remove.
21094 * Makefile.in (base_obj): Remove doprnt.o.
21095 * deps.mk (doprnt.o): Remove.
21097 error: Print 32- and 64-bit integers portably (Bug#8435).
21098 Without this change, on typical 64-bit hosts error ("...%d...", N)
21099 was used to print both 32- and 64-bit integers N, which relied on
21100 undefined behavior.
21101 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21102 * lisp.h (error, verror): Mark as printf-like functions.
21103 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21104 Report overflow in size calculations when allocating printf buffer.
21105 Do not truncate output string at its first null byte.
21106 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21107 Truncate the output at a character boundary, since vsnprintf does not
21109 * charset.c (check_iso_charset_parameter): Convert internal
21110 character to string before calling 'error', since %c now has the
21112 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21113 overflow when computing char to be passed to 'error'. Do not
21114 pass Lisp_Object to 'error'; pass the integer instead.
21115 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21116 formatted with plain %d.
21118 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21120 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21122 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21124 * xterm.c (x_catch_errors): Remove duplicate declaration.
21126 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21128 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21130 2011-04-10 Jim Meyering <meyering@redhat.com>
21132 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21133 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21134 return ssize_t not "int", and use size_t as the buffer length.
21135 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21136 * gnutls.h: Update declarations.
21137 * process.c (read_process_output): Use ssize_t, to match.
21138 (send_process): Likewise.
21140 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21142 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21144 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21146 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21147 Use unsigned char, to match FcChar8 type definition.
21149 * xterm.c (handle_one_xevent):
21150 * xmenu.c (create_and_show_popup_menu):
21151 * xselect.c (x_decline_selection_request)
21152 (x_reply_selection_request): Avoid type-punned deref of X events.
21154 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21156 Fix some uses of `int' instead of EMACS_INT.
21157 * search.c (string_match_1, fast_string_match)
21158 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21159 (scan_buffer, find_next_newline_no_quit)
21160 (find_before_next_newline, search_command, Freplace_match)
21161 (Fmatch_data): Make some `int' variables be EMACS_INT.
21163 * xdisp.c (display_count_lines): 3rd argument and return value now
21164 EMACS_INT. All callers changed.
21165 (pint2hrstr): Last argument is now EMACS_INT.
21167 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21168 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21169 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21170 (decode_coding_utf_16, decode_coding_emacs_mule)
21171 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21172 (decode_coding_ccl, decode_coding_charset)
21173 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21174 (decode_coding_iso_2022, decode_coding_emacs_mule)
21175 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21176 <char_offset, last_offset>: Declare EMACS_INT.

21178 (encode_coding_emacs_mule, encode_invocation_designation)
21179 (encode_designation_at_bol, encode_coding_iso_2022)
21180 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21181 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21183 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21184 (encode_invocation_designation): Last argument P_NCHARS is now
21186 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21187 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21189 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21192 * ccl.c (Fccl_execute_on_string): Declare some variables
21195 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21197 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21199 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21201 * process.c (Fformat_network_address): Doc fix.
21203 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21205 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21207 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21209 * keyboard.c (read_char): Call Lisp function help-form-show,
21210 instead of using internal_with_output_to_temp_buffer.
21211 (Qhelp_form_show): New var.
21212 (syms_of_keyboard): Use DEFSYM macro.
21214 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21218 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21220 * process.c (Flist_processes): Remove to Lisp.
21221 (list_processes_1): Delete.
21223 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21225 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21227 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21229 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21231 Fix more problems found by GCC 4.6.0's static checks.
21233 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21235 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21237 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21239 * xdisp.c (vmessage): Mark as a printf-like function.
21241 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21243 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21245 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21246 printf-like functions.
21247 (tiff_load): Add casts to remove these marks before passing them
21248 to system-supplied API.
21250 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21252 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21253 This avoids several warnings with gcc -Wstrict-overflow.
21254 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21255 directly, rather than having caller test rule sign. This avoids
21256 some unnecessary tests.
21257 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21258 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21259 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21261 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21262 (xfont_open): Avoid unnecessary tests.
21264 * composite.c (composition_gstring_put_cache): Use unsigned integer.

21273 by using the new macro.
21275 * textprop.c (set_text_properties_1): Change while to do-while,
21276 since the condition is always true at first.
21278 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21279 (interval_deletion_adjustment): Return unsigned value.
21282 * process.c (list_processes_1, create_pty, read_process_output):

21298 * print.c (print_error_message): Avoid int overflow.
21300 * font.c (font_list_entities): Redo for clarity,
21301 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

21316 (wordify): Omit three unnecessary tests.
21318 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21321 * casefiddle.c (casify_region): Remove var that is set but not used.
21323 * dired.c (file_name_completion): Remove var that is set but not used.
21325 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21327 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21328 (Finsert_file_contents): Remove unnecessary code checking fd.
21330 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21331 Check for integer overflow on size calculations.
21333 * buffer.c (Fprevious_overlay_change): Remove var that is set
21336 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21337 Remove vars that are set but not used.
21338 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21339 (timer_check_2): Mark vars as initialized.
21341 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21343 * image.c (lookup_image): Remove var that is set but not used.
21344 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21346 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21347 that are set but not used.
21349 * xfns.c (make_invisible_cursor): Don't return garbage
21350 if XCreateBitmapFromData fails (Bug#8410).
21352 * xselect.c (x_get_local_selection, x_handle_property_notify):
21353 Remove vars that are set but not used.
21355 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21356 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21358 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21359 Remove var that is set but not used.
21360 (scroll_bar_windows_size): Now size_t, not int.
21361 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21362 Check for overflow.
21364 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21365 (map_tty_color) [!defined MSDOS]: Likewise.
21367 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21369 * coding.c: Remove vars that are set but not used.
21370 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21371 All callers changed.
21372 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21373 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21374 (decode_coding_charset): Remove vars that are set but not used.
21376 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21377 that is set but not used.
21379 * print.c (print_object): Remove var that is set but not used.
21381 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21382 The gnulib version avoids calling malloc in the usual case,
21383 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21384 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21385 * filelock.c (current_lock_owner): Likewise.
21386 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21387 * sysdep.c: Include allocator.h, careadlinkat.h.
21388 (emacs_no_realloc_allocator): New static constant.
21389 (emacs_readlink): New function.
21390 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21391 ../lib/careadlinkat.h.
21393 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21395 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21396 first non-nil return value).

21417 do not dereference NULL upon failed strdup
21418 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21419 (ns_get_family): Likewise.
21421 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21423 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21425 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21427 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21430 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21432 Add lexical binding.
21434 * window.c (Ftemp_output_buffer_show): New fun.
21435 (Fsave_window_excursion):
21436 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21438 * lread.c (lisp_file_lexically_bound_p): New function.

21441 Bind Qinternal_interpreter_environment.
21442 (Feval_buffer): Bind Qlexical_binding.
21443 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21445 (syms_of_lread): Declare `lexical-binding'.
21447 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21449 * keyboard.c (eval_dyn): New fun.
21450 (menu_item_eval_property): Use it.
21452 * image.c (parse_image_spec): Use Ffunctionp.
21454 * fns.c (concat, mapcar1): Accept byte-code-functions.
21456 * eval.c (Fsetq): Handle lexical vars.
21457 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21458 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21459 (FletX, Flet): Obey lexical binding.
21460 (Fcommandp): Handle closures.
21461 (Feval): New `lexical' arg.
21462 (eval_sub): New function extracted from Feval. Use it almost
21463 everywhere where Feval was used. Look up vars in lexical env.
21465 (Ffunctionp): Move from subr.el.
21466 (Ffuncall): Handle closures.
21467 (apply_lambda): Remove `eval_flags'.
21468 (funcall_lambda): Handle closures and new byte-code-functions.
21469 (Fspecial_variable_p): New function.
21470 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21471 but without exporting it to Lisp.
21473 * doc.c (Fdocumentation, store_function_docstring):
21474 * data.c (Finteractive_form): Handle closures.
21476 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21479 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21481 (exec_byte_code): New function extracted from Fbyte_code to handle new
21482 calling convention for byte-code-functions. Add new byte-codes.
21484 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21486 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21488 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21490 * xdisp.c (redisplay_internal): Fix prototype.
21492 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21494 * xdisp.c (SCROLL_LIMIT): New macro.
21495 (try_scrolling): Use it when setting scroll_limit.
21496 Limit scrolling to 100 screen lines.
21497 (redisplay_window): Even when falling back on "recentering",
21498 position point in the window according to scroll-conservatively,
21499 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21501 (try_scrolling): When point is above the window, allow searching
21502 as far as scroll_max, or one screenful, to compute vertical
21503 distance from PT to the scroll margin position. This prevents
21504 try_scrolling from unnecessarily failing when
21505 scroll-conservatively is set to a value slightly larger than the
21506 window height. Clean up the case of PT below the margin at bottom
21507 of window: scroll_max can no longer be INT_MAX. When aggressive
21508 scrolling is in use, don't let point enter the opposite scroll
21509 margin as result of the scroll.
21510 (syms_of_xdisp) <scroll-conservatively>: Document the
21511 threshold of 100 lines for never-recentering scrolling.
21513 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

21518 (message_log_check_duplicate): Remove parameters `prev_bol' and
21519 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21520 (redisplay_internal): Remove parameter `preserve_echo_area',
21521 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21523 * indent.c (Fvertical_motion):
21524 * window.c (window_scroll_pixel_based, Frecenter):
21525 Don't pass `need_y_p' to `move_it_by_lines'.
21527 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21529 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21530 steal a few bits to be more compact.
21531 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21532 Remove unneeded casts.
21534 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21536 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21538 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21539 binding" message (bug#7967).
21541 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21543 Fix more problems found by GCC 4.6.0's static checks.
21545 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21546 Remove unused local var.
21548 * editfns.c (Fmessage_box): Remove unused local var.
21550 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21551 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21552 Omit unused local vars.
21553 * window.c (shrink_windows): Omit unused local var.
21554 * menu.c (digest_single_submenu): Omit unused local var.
21555 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21556 Omit unused local var.
21558 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21559 Don't assume string length fits in int.
21560 (keyremap_step, read_key_sequence): Use size_t for sizes.
21561 (read_key_sequence): Don't check last_real_key_start redundantly.
21563 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21564 instead of alloca (Bug#8344).
21566 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21567 (Fbacktrace_frame): Don't assume nframes fits in int.
21569 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21571 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21574 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21576 * cm.c (calccost): Turn while-do into do-while, for clarity.
21578 * keyboard.c (syms_of_keyboard): Use the same style as later
21579 in this function when indexing through an array. This also
21580 works around GCC bug 48267.
21582 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21584 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21586 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21587 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21589 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21590 This avoids undefined behavior on integer overflow, and is a bit
21591 more convenient anyway since it is compared to a size_t variable.
21593 Variadic C functions now count arguments with size_t, not int.
21594 This avoids an unnecessary limitation on 64-bit machines, which
21595 caused (substring ...) to crash on large vectors (Bug#8344).

21605 * fns.c (concat): Likewise.
21606 * frame.c (x_set_frame_parameters): Likewise.
21607 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21608 0 if not found, not -1. All callers changed.
21610 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21611 (stack_copy_size): Now size_t, not int.
21612 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21614 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21616 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21617 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21618 All callers changed.
21620 * lisp.h (multibyte_char_to_unibyte):
21621 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21622 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21633 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21634 don't set the hook to nil, but remove the offending function instead.
21635 (Qcommand_hook_internal): Remove, unused.
21636 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21637 Vcommand_hook_internal.
21639 * eval.c (enum run_hooks_condition): Remove.
21640 (funcall_nil, funcall_not): New functions.
21641 (run_hook_with_args): Call each function through a `funcall' argument.

21655 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21656 All callers changed.
21658 * w32.c (_wsa_errlist): Use braces for struct initializers.
21660 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

21713 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21715 * keyboard.c (timer_check): Remove parameter `do_it_now',

21818 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21820 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21821 unconditionally since it does the check itself.
21823 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21825 Fix more problems found by GCC 4.5.2's static checks.
21827 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21828 the first time through the loop, since we know p0 < p1 then.
21829 This also avoids a gcc -Wstrict-overflow warning.
21831 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21832 leading to a memory leak, possible in functions like
21833 load_charset_map_from_file that can allocate an unbounded number
21834 of objects (Bug#8318).
21836 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21837 that could (at least in theory) be that large.
21839 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21840 This is less likely to overflow, and avoids undefined behavior if
21841 overflow does occur. All callers changed. Use strtoul to scan
21842 for the unsigned long integer.
21843 (pint2hrstr): Simplify and tune code slightly.
21844 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21854 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21857 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21859 * process.c (Fmake_network_process): Use socklen_t, not int,
21860 where POSIX says socklen_t is required in portable programs.
21861 This fixes a porting bug on hosts like 64-bit HP-UX, where
21862 socklen_t is wider than int (Bug#8277).
21863 (Fmake_network_process, server_accept_connection):
21864 (wait_reading_process_output, read_process_output):
21867 * process.c: Rename or move locals to avoid shadowing.

21877 Make tparam.h and terminfo.c consistent.
21878 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21879 Include tparam.h instead, since it declares them.
21880 * cm.h (PC): Remove extern decl; tparam.h now does this.
21881 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21882 * terminfo.c: Include tparam.h, to check interfaces.
21883 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21884 (tparam): Adjust signature to match interface in tparam.h;
21885 this removes some undefined behavior. Check that outstring and len
21886 are zero, which they always are with Emacs.
21887 * tparam.h (PC, BC, UP): New extern decls.
21889 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21890 (xftfont_open): Rename locals to avoid shadowing.

21907 (find_automatic_composition, composition_adjust_point): Likewise.
21908 (composition_update_it): Mark var as initialized.
21909 (find_automatic_composition): Mark vars as initialized,
21910 with a FIXME (Bug#8290).

21914 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21915 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21916 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21917 to avoid shadowing.
21919 * textprop.c (property_change_between_p): Remove; unused.
21921 * intervals.c (interval_start_pos): Now static.
21923 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21929 Fix pointer signedness.
21930 (alsa_choose_format): Remove unused local var.
21931 (wav_play): Initialize a variable to 0, to prevent undefined
21932 behavior (Bug#8278).
21934 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21936 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21938 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21939 clobbering (Bug#8298).
21940 * sysdep.c (sys_subshell): Likewise.
21941 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21943 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21944 This should get cleaned up, so that child_setup has the
21945 same signature on all platforms.
21947 * callproc.c (call_process_cleanup): Now static.
21948 (relocate_fd): Rename locals to avoid shadowing.
21950 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21952 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21953 not to be necessary, and produces flickering.
21955 2011-03-20 Glenn Morris <rgm@gnu.org>
21957 * config.in: Remove file.
21959 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21973 * xfaces.c (Fx_load_color_file):
21974 Read color file from absolute filename (bug#8250).

21989 (sigchld_handler): Now static.
21991 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
21992 That way, the code declares only the vars that it needs.

22002 (CONSTANTLIM): Remove; unused.
22003 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22004 Define only if needed.
22006 * unexelf.c (unexec): Name an expression,
22007 to avoid gcc -Wbad-function-cast warning.
22008 Use a different way to cause a compilation error if anyone uses
22009 n rather than nn, a way that does not involve shadowing.
22010 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22012 * deps.mk (unexalpha.o): Remove; unused.
22014 New file unexec.h, the (simple) interface for unexec (Bug#8267).

22104 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22105 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22107 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.

22109 (Fmemory_limit): Cast sbrk's returned value to char *.

22135 (RETALLOC_IF): Define only if needed.
22136 (WORDCHAR_P): Likewise. This one is never needed, but is used
22137 only in a comment talking about a compiler bug, so put inside
22138 the #if 0 of that comment.

22166 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22167 New macros, so that the caller can use some names other than
22168 gcpro1, gcpro2, etc.
22169 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22171 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22172 argument, for consistency with GCPRO2_VAR, etc: it is now the
22173 prefix of the variable, not the variable itself. All uses
22175 * dired.c (directory_files_internal, file_name_completion):
22176 Rename locals to avoid shadowing.
22178 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22179 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22180 dired.c's scmp function, had undefined behavior.
22181 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22182 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22183 * buffer.h: ... to here, because these macros use current_buffer,
22184 and the new implementation with inline functions needs to have
22185 current_buffer in scope now, rather than later when the macros
22187 (downcase, upcase1): New static inline functions.
22188 (DOWNCASE, UPCASE1): Reimplement using these functions.
22189 This avoids undefined behavior in expressions like
22190 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22191 from race conditions in accessing the global variables
22192 case_temp1 and case_temp2.
22193 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

22230 * buffer.c (fix_overlays_before): Mark locals as initialized.
22231 (fix_start_end_in_overlays): Likewise. This function should be
22232 simplified by using pointers-to-pointers, but that's a different

22235 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22236 (report_overlay_modification): Rename locals to avoid shadowing.

22241 to suppress a gcc -Wclobbered warning that does not seem to be right.
22242 (MAXPATHLEN): Define only if needed.
22244 * process.c (serial_open, serial_configure): Move decls from here ...
22245 * systty.h: ... to here, so that they can be checked.
22247 * fns.c (get_random, seed_random): Move extern decls from here ...
22248 * lisp.h: ... to here, so that they can be checked.
22250 * sysdep.c (reset_io): Now static.
22251 (wait_for_termination_signal): Remove; unused.
22253 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22257 (DENSE_TABLE_SIZE): Remove; unused.
22258 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22259 (describe_map_tree):
22260 Rename locals to avoid shadowing.
22262 * keyboard.c: Declare functions static if they are not used elsewhere.

22603 (decode_coding_emacs_mule): Mark variables that gcc
22604 -Wuninitialized does not deduce are never used uninitialized.
22605 (detect_coding_iso_2022): Initialize a local variable that might
22606 be used uninitialized. Leave a FIXME because it's not clear that
22607 this initialization is needed. (Bug#8211)
22608 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
22609 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):
