105 * sysdep.c (list_system_processes)
106 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
107 Make it a stub in this case; otherwise the build might fail,
108 and this code hasn't been tested on such hosts anyway.
109 Problem reported by Nelson H. F. Beebe in
110 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
111 and analyzed by Jérémie Courrèges-Anglas in

124 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
125 * filelock.c: Include <c-ctype.h>.
126 (MAX_LFINFO): New top-level constant.
127 (lock_info_type): Remove members pid, boot_time. Add members at,
128 dot, colon. Change user member to be the entire buffer, not a
129 pointer. This allows us to handle the case where a foreign
130 pid or boot time exceeds the local range. All uses changed.
131 (LINKS_MIGHT_NOT_WORK): New constant.
132 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
133 (defined_WINDOWSNT): Remove.
134 (MAKE_LOCK_NAME, file_in_lock_file_name):
135 Always use .#FILE (not .#-FILE) for the file lock,
136 even if it is a regular file.
137 (rename_lock_file): New function.
138 (create_lock_file): Use it.
139 (create_lock_file, read_lock_data):
140 Prefer a symbolic link for the lock file, falling back on a
141 regular file if symlinks don't work. Do not try to create
142 symlinks on MS-Windows, due to security hassles. Stick with
143 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
144 link, rename, unlink, mkstemp) when creating locks, as a GNUish
145 host may be using a Windowsish file system, and cannot use
146 MS-Windows-only system calls. Fall back on mktemp if mkstemp
147 doesn't work. Don't fail merely because of a symlink-contents
148 length limit in the current file system; fall back on regular
149 files. Increase the symlink contents length limit to 8 KiB, this
150 should be big enough for any real use and doesn't crunch the
152 (create_lock_file, lock_file_1, read_lock_data):
153 Simplify allocation of lock file buffers now that they fit in 8 KiB.
154 (lock_file_1): Return error number, not bool. All callers changed.
155 (ELOOP): New macro, if not already defined.
156 (read_lock_data): Return size of lock file contents, not Lisp object.
157 All callers changed. Handle a race condition if some other process
158 replaces a regular-file lock with a symlink lock or vice versa,
159 while we're trying to read the lock.
160 (current_lock_owner): Parse contents more carefully, to help avoid
161 confusing a regular-file lock with some other application's use
162 of the file. Check for lock file contents being too long, or
163 not parsing correctly.
164 (current_lock_owner, lock_file):
165 Allow foreign pid and boot times that exceed the local range.
166 (current_lock_owner, lock_if_free, lock_file):
167 Simplify allocation of lock file contents.
168 * w32.c (sys_rename_replace): New function, containing most of
169 the contents of the old sys_rename.
170 (sys_rename): Use it.
171 (fchmod): New dummy function.
172 * w32.h (sys_rename_replace, fchmod): New decls.
174 2013-03-05 Eli Zaretskii <eliz@gnu.org>
176 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
177 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
178 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
179 <dmantipov@yandex.ru>.
181 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
183 * composite.c (get_composition_id, fill_gstring_header):
184 Use make_uninit_vector where appropriate.
185 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
186 * xselect.c (clean_local_selection_data): Likewise.
188 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
190 Fix misuse of ImageMagick that caused core dump (Bug#13846).
191 * image.c (imagemagick_load_image): Calculate height and width
192 after flattening the image, not before.
194 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
196 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
197 * ftfont.c (ftfont_shape_by_flt): Likewise.
198 * w32uniscribe.c (uniscribe_shape): Likewise.
200 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
202 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
203 The old approach, which fell back on DIR/.#FILE.0 through
204 DIR/.#FILE.9, had race conditions that could not be easily fixed.
205 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
206 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
207 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
208 because the locking mechanism was never reliable in that case).
209 This patch fixes this and other bugs discovered by a code
210 inspection that was prompted by
211 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
212 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
213 to avoid interoperability problems between the MS-Windows and
214 non-MS-Windows implementations. MS-Windows and non-MS-Windows
215 instances of Emacs now ignore each others' locks.
216 * filelock.c (defined_WINDOWSNT): New constant.
217 (MAKE_LOCK_NAME, fill_in_lock_file_name):
218 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
219 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
220 regular files on MS-Windows hosts.
221 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
222 Use SAFE_ALLOCA to avoid problems with long file names.
223 (MAX_LFINFO): Now a local constant, not a global macro.
224 (IS_LOCK_FILE): Remove.
225 (lock_file_1): Don't inspect errno if symlink call succeeds;
227 (lock_file): Document that this function can return if lock
229 (lock_file): Don't access freed storage.
231 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
233 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
235 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
237 * textprop.c: Use bool for booleans.
238 (validate_interval_range, Fadd_text_properties)
239 (Fremove_text_properties): Prefer bool to int when either works.
241 2013-03-02 Eli Zaretskii <eliz@gnu.org>
243 * textprop.c (Fadd_text_properties, Fremove_text_properties): If
244 the interval tree changes as a side effect of calling
245 modify_region, re-do processing starting from the call to
246 validate_interval_range. (Bug#13743)
248 2013-02-28 Eli Zaretskii <eliz@gnu.org>
250 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
253 2013-02-27 Eli Zaretskii <eliz@gnu.org>
255 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
256 _SH_DENYRW flag, instead of emacs_open, to deny any other process
257 access to the lock file until it is written and closed.
260 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
262 * callint.c (Qcall_interactively):
263 * macros.c (Qexecute_kbd_macro):
266 2013-02-26 Bastien Guerry <bzg@gnu.org>
268 * window.c (Frecenter): Tiny docstring enhancement.
270 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
272 Minor textprop integer cleanup.
273 * intervals.h, textprop.c (add_text_properties_from_list):
274 Return void, not int, since nobody uses the return value.
275 * textprop.c (validate_plist, add_properties, remove_properties)
276 (Fadd_text_properties):
277 Don't assume list length fits in int.
278 (interval_has_all_properties, interval_has_some_properties)
279 (interval_has_some_properties_list, add_properties, remove_properties)
280 (Fadd_text_properties, Fremove_text_properties)
281 (Fremove_list_of_text_properties, text_property_stickiness):
282 Use bool for booleans.
283 (Fadd_text_properties, Fremove_text_properties):
284 (Fremove_list_of_text_properties):
285 Reindent do-while as per GNU style.

289 Implement CLASH_DETECTION for MS-Windows.
291 * filelock.c [WINDOWSNT]: Include w32.h.
292 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
293 function of that name. Up-case the macro arguments.
294 (IS_LOCK_FILE): New macro.
295 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
296 (create_lock_file): New function, with body extracted from
298 [WINDOWSNT]: Implement lock files by writing a regular file with
299 the lock information as its contents.
300 (read_lock_data): New function, on Posix platforms just calls
302 [WINDOWSNT]: Read the lock info from the file.
303 (current_lock_owner): Call read_lock_data instead of calling
304 emacs_readlinkat directly.
305 (lock_file) [WINDOWSNT]: Run the file name through
308 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
309 just check if the process by that PID exists.
311 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
312 also present, as doing so will fail to error out if the file
315 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
317 * textprop.c (Fadd_text_properties, Fremove_text_properties)
318 (Fremove_list_of_text_properties): Skip all of the intervals in
319 the region between START and END that already have resp. don't
320 have the requested properties, not just the first one. Add
321 assertions that the loop afterwards always modifies the
322 properties. (Bug#13743)

354 so simplify-away some unnecessary exactness.
355 (POINTER): Remove; all uses removed.
356 (data_space_start): Now char *, to avoid casts.
357 (exceeds_lisp_ptr): New function, replacing the old

472 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
474 2013-02-15 Eli Zaretskii <eliz@gnu.org>
476 * keyboard.c (read_char): Fix calculation of auto-save time out
477 when auto-save-timeout is less than 4. (Bug#13720)
479 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
480 time. Improve diagnostics in DebPrint. (Bug#13546)
482 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
483 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
484 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
485 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
486 make sure errno is set to an appropriate value. (Bug#13546)
487 (socket_to_fd): Add assertion against indexing fd_info[] with a
488 value that is out of bounds.
489 (sys_accept): If fd is negative, do not set up the child_process
490 structure for reading.
492 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
494 * composite.c (fill_gstring_header): Remove useless prototype.
496 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
497 * print.c (PRINTDECLARE, print_object):
498 * search.c (compile_pattern, fast_looking_at, search_buffer):
499 (simple_search, boyer_moore, Freplace_match):
500 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
501 (get_overlay_arrow_glyph_row, display_mode_element):
502 (decode_mode_spec_coding, message3):
503 * xfaces.c (face_at_string_position): Use bool for booleans.
506 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
508 Fix AIX port (Bug#13650).
509 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
510 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
511 was #undeffed earlier, so it cannot be used as a macro here.
512 Use the constant and not the macro.
514 2013-02-15 Eli Zaretskii <eliz@gnu.org>
516 * w32proc.c (new_child): If no vacant slots are found in
517 child_procs[], make another pass looking for slots whose process
518 has exited or died. (Bug#13546)
520 * w32.c (sys_pipe): When failing due to file descriptors above
521 MAXDESC, set errno to EMFILE.
522 (_sys_read_ahead): Update cp->status when failing to read serial
523 communications input, so that the status doesn't stay at
524 STATUS_READ_IN_PROGRESS. (Bug#13546)
526 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
528 * gtkutil.c (tb_size_cb): New function.
529 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
531 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
533 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
536 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
538 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
540 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
542 * font.c (font_range): Add pos_byte argument. Adjust comment
544 * font.h (font_range): Adjust prototype.
545 * composite.c (autocmp_chars): Pass byte position to font_range.
546 Break long line. Remove useless prototype and format comment.
548 2013-02-13 Glenn Morris <rgm@gnu.org>
550 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
552 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
554 Improve AIX port some more (Bug#13650).
555 With this, it should be as good as it was in 23.3, though it's
556 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
557 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
558 * unexaix.c (start_of_text): Remove.
559 (_data, _text): Declare as char[], not int, as AIX manual suggests.
560 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
561 (orig_load_scnptr, orig_data_scnptr):
562 Now off_t, not long, since they are file offsets.
563 (make_hdr): Use _data, not start_of_data ().
564 This is the key part of the fix.
565 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
566 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
568 * pre-crt0.c (data_start): Initialize to 1.
569 This ports to compilers that optimize the external declaration
570 'int x = 0;' as if it were 'int x;' to shrink the executable.
572 Improve AIX port (Bug#13650).
573 This doesn't fix the bug, but it makes progress: Emacs builds now.
574 * unexaix.c: Include inttypes.h, stdarg.h.
575 (report_error, report_error_1): Mark as _Noreturn.
576 (report_error): Don't report the wrong errno.
577 (report_error_1): Now varargs. All callers changed.
578 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
579 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
580 (write_ptr): Use %p to print address rather than %lx and a cast
581 to unsigned long. Grow buffer a bit, to be safer.
583 2013-02-13 Eli Zaretskii <eliz@gnu.org>
585 * bidi.c (bidi_resolve_neutral): After finding the next
586 non-neutral character, accept NEUTRAL_ON type as well, because
587 directional control characters, such as LRE and RLE, have their
588 type converted to that by bidi_resolve_weak. This avoids aborts
589 when LRE/RLE follows a run of neutrals.
590 (bidi_move_to_visually_next): Assert that return value of
591 bidi_peek_at_next_level is non-negative. Negative values will
594 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
596 Minor getenv-related fixes.
597 * callproc.c (Fcall_process_region) [!DOS_NT]:
598 Avoid unnecessary duplicate call to getenv.
599 * callproc.c (init_callproc):
600 * dispnew.c (init_display):
601 * sysdep.c (sys_subshell):
602 Omit unnecessary cast of getenv or egetenv.
604 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
606 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
609 2013-02-12 Eli Zaretskii <eliz@gnu.org>
611 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
613 (display_line): Set w->region_showing to the value of
614 it->region_beg_charpos, not to -1. This fixes redisplay
615 optimization when cursor is moved up after M->. (Bug#13623)
617 (try_scrolling): Scroll text up more if point is too close to ZV
618 and inside the scroll margin. This makes sure point is moved
619 outside the scroll margin in these cases.
621 * window.h (struct window): region_showing can no longer be
624 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
626 Tune by using memchr and memrchr.
627 * doc.c (Fsnarf_documentation):
628 * fileio.c (Fsubstitute_in_file_name):
629 * search.c (find_newline, scan_newline):
630 * xdisp.c (pos_visible_p, display_count_lines):
631 Use memchr and memrchr rather than scanning byte-by-byte.
632 * search.c (find_newline): Rename from scan_buffer.
633 Omit first arg TARGET, as it's always '\n'. All callers changed.
635 Clean up read_key_sequence a tiny bit more.
636 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
637 (read_key_sequence): Remove unused locals.
639 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
641 Clean up read_key_sequence a bit; reread active keymaps after first event.
642 * keyboard.c (read_char, read_char_x_menu_prompt)
643 (read_char_minibuf_menu_prompt):
644 Replace nmaps+maps with a single `map' arg.
645 (follow_key): Operate on a single map.
646 (active_maps): New function.
647 (test_undefined): Also return true for nil bindings.
648 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
649 a single (composed) keymap. Remember `first_event' to choose the right
650 set of active keymaps. Recompute the set of keymaps after receiving
651 the first event. Remove GOBBLE_FIRST_EVENT.
652 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
653 * keyboard.h (read_char): Update declaration.
654 * lread.c (read_filtered_event): Adjust call to read_char.
656 2013-02-11 Eli Zaretskii <eliz@gnu.org>
658 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
659 Don't use the limitation on backwards movement when lines are truncated
660 in the window. (Bug#13675)
662 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
664 * marker.c (set_marker_internal): If desired position is passed
665 as a marker, avoid call to buf_charpos_to_bytepos.
666 * window.c (Fset_window_point): Omit redundant type checking.
667 (Fset_window_start): Likewise. Format comment.
668 (window_scroll_pixel_based): Use set_marker_restricted_both
669 with character and byte positions obtained from an iterator.
670 (Fset_window_configuration): Use set_marker_restricted_both.
671 * xdisp.c (message_dolog): Likewise.
673 2013-02-10 Eli Zaretskii <eliz@gnu.org>
675 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
676 When text lines are longer than window's screen lines, don't move back
677 too far. This speeds up some redisplay operations. (Bug#13675)
679 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
681 * syntax.c (scan_sexps_forward): Fix byte position calculation
682 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
684 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
686 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
689 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
691 Minor hashing refactoring.
692 * fns.c (SXHASH_REDUCE): Move to lisp.h.
693 (sxhash_float): Return EMACS_UINT, for consistency with the other
695 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
696 non-static inline function and therefore can't use static vars.
697 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
698 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
699 with the other hash functions.
701 2013-02-09 Eli Zaretskii <eliz@gnu.org>
703 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
704 XXXXXX part of the temporary file pattern is not downcased even
705 when w32-downcase-file-names is non-nil. (Bug#13661)
707 * xdisp.c (decode_mode_spec): Remove handling of %t.
709 * msdos.c (careadlinkatcwd): Remove.
711 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
713 * lread.c (skip_dyn_bytes): New function (bug#12598).
714 (read1): Use it. Use getc instead of READCHAR to read bytes.
715 (load_each_byte): Remove. Update users.
717 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
719 * search.c (scan_buffer): Calculate end byte position just once.
720 (scan_newline): Do not recalculate start_byte.
721 (search_command): Use eassert.
722 * syntax.c (struct lisp_parse_state): New member location_byte.
723 (scan_sexps_forward): Record from_byte and avoid redundant
724 character to byte position calculation ...
725 (Fparse_partial_sexp): ... here. Break too long line.
727 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
729 * lisp.h (make_uninit_vector): New function.
730 * alloc.c (Fvector, Fmake_byte_code):
731 * ccl.c (Fregister_ccl_program):
732 * charset.c (Fdefine_charset_internal, define_charset_internal):
733 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
734 * composite.c (syms_of_composite):
735 * font.c (Fquery_font, Ffont_info, syms_of_font):

739 * nsselect.m (clean_local_selection_data):
740 * syntax.c (init_syntax_once):
741 * w32unsubscribe.c (uniscribe_shape):
742 * window.c (Fcurrent_window_configuration):
743 * xfaces.c (Fx_family_fonts):
744 * xselect.c (selection_data_to_lisp_data): Use it.
746 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
748 * coding.c (Fdefine_coding_system_internal): Use AREF where
749 argument is known to be a vector.
750 * fns.c (Flocale_info): Likewise for ASET.
751 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
752 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
754 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
756 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
759 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
760 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
761 updateCollectionBehaviour.
763 * nsterm.m (NEW_STYLE_FS): Remove.
764 (ns_last_use_native_fullscreen): New variable.
765 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
766 (x_set_window_size): Do not take title bar and tool bar into account
767 if isFullscreen returns YES.
768 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
769 (check_native_fs): New function.
770 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
771 (ns_term_init): Remove NEW_STYLE_FS.
772 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
773 and tool bar if isFullscreen returns NO.
774 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
775 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
777 (window:willUseFullScreenPresentationOptions:): New method.
778 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
779 Hide toolbar if not enabled (Bug#13444).
780 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
781 Restore tool bar if enabled, hide it otherwise (Bug#13444).
782 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
783 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
784 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
785 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
786 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
787 (syms_of_nsterm): Add ns-use-native-fullscreen.
789 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
791 * fileio.c (Qchoose_write_coding_system): Now static.
793 2013-02-04 Eli Zaretskii <eliz@gnu.org>
795 * xdisp.c (window_buffer_changed): region_showing can be negative,
796 which still means region is being displayed.
797 (redisplay_internal): Resurrect code that forced redisplay of the
798 whole window when showing region and the mark has changed.
799 Record the new mark position to allow redisplay optimizations.
800 (display_line): If it->region_beg_charpos is non-zero, set the
801 window's region_showing member to -1. (Bug#13623) (Bug#13626)
803 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
804 not bitfield of 1 bit.
806 2013-02-03 Daniel Colascione <dancol@dancol.org>
808 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
809 daemon mode works on cygw32 when Emacs is installed and not just
812 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
814 Avoid file time stamp bug on MS-Windows (Bug#13149).
815 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
816 as FAT32 doesn't update time stamps when truncating them.
817 Also, check that a file time stamp is not a multiple of 100 ns;
818 this should catch all instances of the problem on MS-Windows,
819 as its native file system resolution is 100 ns or worse, and
820 checking for a non-multiple of 100 ns should impose only a small
821 overhead on systems with ns resolution.
823 2013-02-02 Eli Zaretskii <eliz@gnu.org>
825 Avoid encoding file names on MS-Windows when they need to be run
826 through dostounix_filename.
827 * w32.c (normalize_filename): Accept an additional argument
828 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
829 downcase it even if w32-downcase-file-names is non-nil.
830 (dostounix_filename): Accept an additional argument MULTIBYTE and
831 pass it to normalize_filename.
832 (emacs_root_dir): Adjust.
834 * msdos.h (dostounix_filename): Adjust prototype.
836 * w32.h (dostounix_filename): Adjust prototype.
838 * msdos.c (dostounix_filename): Accept an additional argument and
840 (init_environment): Adjust callers of dostounix_filename.
842 * fileio.c (Ffile_name_directory, file_name_as_directory)
843 (directory_file_name, Fexpand_file_name)
844 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
846 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
848 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
849 variables, as egetenv is case-insensitive for DOS_NT.
851 * dired.c (file_name_completion): Don't call Fdirectory_file_name
852 with an encoded file name.
854 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
855 Adjust calls to dostounix_filename.
857 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
859 * unexw32.c (unexec): Adjust call to dostounix_filename.
861 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
863 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
866 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
869 * callproc.c (Fcall_process): Make sure program name in PATH and
870 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
871 is passed to exec/spawnve, which fails unless the file-name
874 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
875 even if w32-quote-process-args is nil.
877 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
879 Fix timestamp bug when write-region appends nothing (Bug#13149).
880 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
881 the file's time stamp doesn't change if Emacs happens to write nothing
882 to the file, and on a buggy file system this could cause Emacs to
883 incorrectly infer that the file system doesn't have the bug.
884 Avoid this problem by inhibiting the inference in this case.
886 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
888 * window.h (struct window): Convert base_line_number, base_line_pos
889 and column_number_displayed members from Lisp_Object to ptrdiff_t.
890 Convert region_showing member from Lisp_Object to bitfield.
891 Remove sequence_number member. Adjust comments.
892 * window.c (sequence_number): Remove.
893 (make_window): Initialize column_number_displayed.
894 * print.c (print_object): Follow the printed representation of
895 frames and print window pointer to distinguish between windows.
896 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
897 * xdisp.c (wset_base_line_number, wset_base_line_pos)
898 (wset_column_number_displayed, wset_region_showing): Remove.
899 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
900 (try_scrolling, try_cursor_movement, redisplay_window)
901 (try_window_reusing_current_matrix, try_window_id, display_line)
902 (display_mode_lines, decode_mode_spec): Adjust users.
903 * .gdbinit (pwinx): Do not print sequence_number.
905 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
907 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
908 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
909 * dired.c: Include <fcntl.h>.
910 (open_directory): New function, which uses open and fdopendir
911 rather than opendir. DOS_NT platforms still use opendir, though.
912 (directory_files_internal, file_name_completion): Use it.
913 (file_attributes): New function, with most of the old Ffile_attributes.
914 (directory_files_internal, Ffile_attributes): Use it.
915 (file_attributes, file_name_completion_stat): First arg is now fd,
916 not dir name. All uses changed. Use fstatat rather than lstat +
918 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
919 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
920 (emacs_readlinkat): New function, with much of the old
921 Ffile_symlink_p, but with an fd argument for speed.
922 It uses readlinkat rather than careadlinkatcwd, so that it
923 need not assume the working directory.
924 (Ffile_symlink_p): Use it.
925 * filelock.c (current_lock_owner): Use emacs_readlinkat
926 rather than emacs_readlink.
927 * lisp.h (emacs_readlinkat): New decl.
928 (READLINK_BUFSIZE, emacs_readlink): Remove.
929 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
930 (emacs_norealloc_allocator, emacs_readlink): Remove.
931 This stuff is moved to fileio.c.
932 * w32.c (fstatat, readlinkat): New functions.
933 (careadlinkat): Don't check that fd == AT_FDCWD.
934 (careadlinkatcwd): Remove; no longer needed.
936 2013-01-31 Glenn Morris <rgm@gnu.org>
938 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
939 (Fwrite_region): Update for new choose_write_coding_system args.
940 Move the last piece of choose_write_coding_system here. (Bug#13522)

945 * w32.c (sys_open): Zero out the flags for the new file descriptor.
946 (sys_close): Zero out the flags for the file descriptor before
947 closing it. (Bug#13546)
949 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
950 (logon_network_drive, stat_worker, symlink, chase_symlinks):
951 Use CharNextExA and CharPrevExA to iterate over file names encoded in
954 * w32.c (w32_get_long_filename, init_environment, readlink):
955 Support file names encoded in DBCS codepages.
956 (readlink): Use the current file-name-coding-system, not the ANSI
957 codepage, to decode and handle targets of symlinks.
959 2013-01-28 Eli Zaretskii <eliz@gnu.org>
961 * w32.c (opendir): Now accepts a 'const char *'.

965 Remove obsolete redisplay code. See the discussion at
966 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
967 * dispnew.c (preemption_period, preemption_next_check): Remove.
968 (Vredisplay_preemption_period): Likewise.
969 (update_frame, update_single_window, update_window, update_frame_1):
970 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
971 used, following the 2012-06-22 change.
973 2013-01-25 Eli Zaretskii <eliz@gnu.org>
975 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
977 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
979 * font.c (num_fonts): Remove the leftover from old

985 2013-01-25 Eli Zaretskii <eliz@gnu.org>
987 * w32.c (max_filename_mbslen): New function.
988 (normalize_filename, readdir): Use it to detect locales where ANSI
989 encoding of file names uses a double-byte character set (DBCS).
990 If a DBCS encoding is used, advance by characters using
991 CharNextExA, instead of incrementing a 'char *' pointer.
992 Use _mbslwr instead of _strlwr. (Bug#13515)
994 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
995 request of memory reservation to 1.7GB. (Bug#13065)
997 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
999 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1000 at check_extra_latin label. (Bug#13505)
1002 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1004 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1005 Avoid redundant calls to strlen.
1007 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1009 Drop async_visible and async_iconified fields of struct frame.
1010 This is possible because async input is gone; for details, see
1011 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1012 * frame.h (struct frame): Remove async_visible and async_iconified
1013 members, convert garbaged to unsigned bitfield. Adjust comments.
1014 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1015 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1016 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1017 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1018 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1020 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1021 properly. Likewise for obscured.
1023 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1026 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1028 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1030 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1031 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1033 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1035 * xdisp.c (message2, message2_nolog): Remove functions.
1036 (message3, message3_nolog): Extract nbytes and multibyteness directly
1037 from the string. Change all callers.
1038 (message3_nolog): Don't set message_enable_multibyte since set_message
1039 will reset it anyway.
1040 (message1, message1_nolog): Use message3.
1041 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1042 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1043 (set_message): Drop all but the second arg, which has to be a string.
1044 (set_message_1): Simplify now that we know that a1 is NULL and the
1045 second arg is a string.
1046 * frame.h (struct frame): Remove `message_buf' field.
1047 Use glyphs_initialized_p instead.
1048 (FRAME_MESSAGE_BUF): Remove macro.
1049 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1050 * lisp.h (message2, message2_nolog): Remove declarations.
1051 (message3, message3_nolog): Update declarations.
1052 * keyboard.c (read_char_minibuf_menu_text)
1053 (read_char_minibuf_menu_width): Remove vars.
1054 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1055 to correctly handle multibyte strings.

1057 * editfns.c (message_text, message_length): Remove vars.
1058 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1059 * fileio.c (auto_save_error): Use message3 instead of message2.
1060 * dispnew.c (adjust_frame_message_buffer): Remove function.
1062 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1064 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1065 real estate used for the tool bar and the menu bar.
1067 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1069 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1070 hidden buffer is prepared to modification (Bug#13164).
1072 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1074 * window.h (struct window): Change window_end_valid member from
1075 Lisp_Object to a bitfield. Adjust comments.
1076 (wset_window_end_valid): Remove.
1077 * window.c (adjust_window_count): Clear window_end_valid.
1078 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1079 (Fwindow_line_height, set_window_buffer, Frecenter)

1081 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1082 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1083 * xdisp.c (check_window_end, reconsider_clip_changes)
1084 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1085 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1086 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1088 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1090 * xdisp.c (mark_window_display_accurate): Simplify the loop
1091 assuming that the only one of vchild, hchild or buffer window
1092 slots is non-nil. Call mark_window_display_accurate_1 for
1093 the leaf windows only.
1094 (mark_window_display_accurate_1): Always assume leaf window.
1097 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1099 * emacs.c (Qkill_emacs_hook): Now static.
1101 * fileio.c (Finsert_file_contents): Simplify.
1102 Remove unnecessary assignments and tests.
1104 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1106 * w32.c (acl_set_file): Don't test for errors unless
1107 set_file_security returns FALSE. Avoids spurious errors when
1110 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1112 * fileio.c (Finsert_file_contents): Revert code introduced at
1113 2013-01-18 in favor of the simpler and generally better fix.
1114 Save stack space by removing 'buffer' and reusing 'read_buf'
1117 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1119 * lisp.h (eabs): Define unconditionally (Bug#13419).
1120 The old "#if !defined (eabs)" was an unnecessary revenant of back
1121 when this macro was called "abs". Document 'eabs' better.
1123 2013-01-19 Glenn Morris <rgm@gnu.org>
1125 * fns.c (Frandom): Doc fix.
1127 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1129 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1130 segfault when there are lots of overlays.
1132 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1133 when there are lots of overlays.
1134 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1135 for the details and a way to reproduce.
1137 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1139 * fileio.c: Use O_APPEND to append.
1140 This corresponds better to the natural interpretation of "append",
1141 and avoids the need to open the output file twice, or to invoke
1142 lseek when APPEND is neither nil nor a number.
1143 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1144 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1145 file possibly twice, and lseeking to its end; this avoids the
1146 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1147 at the same time: the combination is never needed and apparently
1148 it doesn't work with DOS_NT.
1150 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1151 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1153 Allow floating-point file offsets.
1154 Problem reported by Vitalie Spinu in
1155 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1156 * fileio.c (emacs_lseek): Remove.
1157 (file_offset): New function.
1158 (Finsert_file_contents, Fwrite_region): Use it.
1160 2013-01-19 Chong Yidong <cyd@gnu.org>
1162 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1163 aborting on Fsignal (Bug#13289).
1165 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1167 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1168 set_file_security as failure due to insufficient privileges.
1169 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1170 (fstat): Return owner and group like 'stat' and 'lstat' do.
1172 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1174 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1175 The bug was observed on Ubuntu operating inside a virtual machine,
1176 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1177 The workaround introduces a race condition on non-buggy hosts,
1178 but it's an unlikely race and anyway there's a nearly identical
1179 nearby race that can't be fixed.
1180 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1182 (Fwrite_region): Test for file system time stamp bug.
1183 (init_fileio): New function.
1184 * lisp.h (init_fileio): Declare it.
1185 * emacs.c (main): Call it.
1187 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1188 and make it more consistent with other stat-failure diagnostics.
1190 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1192 Fix crash when inserting data from non-regular files.
1193 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1194 for the error description produced by valgrind.
1195 * fileio.c (read_non_regular): Rename to read_contents.
1196 Free Lisp_Save_Value object used to pass parameters.
1197 (read_non_regular_quit): Rename to read_contents_quit.
1198 (Finsert_file_contents): Redesign internal file reading loop to adjust
1199 gap and end positions after each read and so help make_gap to work
1200 properly. Do not signal an I/O error too early and so do not leave
1201 not yet decoded characters in a buffer, which was the reason of
1202 redisplay crash. Use list2 to build return value. Adjust comments.
1204 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1206 Close a race when statting and reading files (Bug#13149).
1207 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1208 This avoids a race if the file is renamed between stat and open.
1209 This race is not the problem originally noted in Bug#13149;
1210 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1212 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1219 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1220 * alloc.c (format_save_value): Rename to make_save_value.
1221 (make_save_pointer): New function.
1222 (record_xmalloc): Use make_save_pointer.
1223 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1224 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1225 Change users of make_save_value to make_save_pointer.
1226 Likewise for format_save_value and make_save_value.

1239 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1241 * keymap.c (map_keymap_internal): Use format_save_value.
1242 (map_keymap_char_table_item): Adjust accordingly.
1243 * fileio.c (non_regular_fd, non_regular_inserted)
1244 (non_regular_nbytes): Remove.
1245 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1246 Use format_save_value to pass parameters to read_non_regular.
1247 (read_non_regular): Use XSAVE_ macros to extract parameters.
1249 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1251 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1253 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1255 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1256 extraction from any Lisp_Save_Value slot. Add type checking.
1257 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1258 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1259 * xselect.c: All users changed.
1261 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1272 (save_excursion_restore): Use XSAVE_OBJECT.
1274 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1276 Avoid needless casts with XSAVE_POINTER.
1277 * alloc.c (mark_object) [GC_MARK_STACK]:
1278 * dired.c (directory_files_internal_unwind):
1279 * fileio.c (do_auto_save_unwind):
1280 * gtkutil.c (pop_down_dialog):
1281 * keymap.c (map_keymap_char_table_item):
1282 * lread.c (load_unwind):
1283 * nsmenu.m (pop_down_menu):
1284 * print.c (print_object) [GC_MARK_STACK]:
1285 * xfns.c (clean_up_file_dialog):
1286 * xmenu.c (cleanup_widget_value_tree):
1287 Omit casts between XSAVE_POINTER and a pointer type.
1289 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

1292 * eval.c (eval_sub): Protect `form' from being GCed before its
1293 car and cdr becomes protected with the backtrace entry.
1295 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1297 Make Lisp_Save_Value more versatile storage for up to four objects.
1298 * lisp.h (toplevel): Enumeration to describe types of saved objects.
1299 (struct Lisp_Save_Value): New layout. Adjust comments.
1300 (XSAVE_POINTER): New macro.
1301 (XSAVE_INTEGER): Likewise.
1302 (allocate_misc): Add prototype.
1303 (free_misc): Likewise.
1304 * alloc.c (allocate_misc): Now global.
1305 (free_misc): Likewise. Adjust comment.
1306 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1307 (free_save_value): Likewise.
1308 (mark_object): Likewise.
1309 * editfns.c (save_excursion_save): Pack everything within
1310 Lisp_Save_Value and so avoid xmalloc.
1311 (save_excursion_restore): Adjust to match new layout. Use free_misc
1312 because we do not allocate extra memory any more. Add eassert.
1313 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1314 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1315 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,

1326 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1328 Fix SIGDANGER handlers, for AIX (Bug#13408).
1329 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1330 Move handlers here from emacs.c; they were out of place.
1332 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1334 * xterm.c (syms_of_xterm): Adjust documentation for
1335 scroll-bar-adjust-thumb-portion.

1366 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
1367 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
1368 Clear tzvalbuf_in_environ if this workaround is in effect.
1369 Problem and fix reported by Kazuhiro Ito.
1371 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

1380 string cross-reference(s).
1382 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1384 Avoid unnecessary byte position calculation for the gap movement.
1385 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1386 anyway, all of them should use move_gap_both instead.
1387 * lisp.h (move_gap): Remove prototype.
1388 * insdel.c (move_gap): Remove.
1389 (move_gap_both): Add eassert.
1390 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

1398 * term.c (init_tty): Use them instead of rolling our own code.
1399 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1400 switches from 'signal' to 'pthread_sigmask', which is safer in
1401 multithreaded applications.
1402 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1403 which has already arranged for that.
1404 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1405 This is the main part of the bug fix.

1419 * buffer.c (buffer_slot_type_mismatch): Remove.
1420 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

1424 left-margin-width, right-margin-width, left-fringe-width,
1425 right-fringe-width, scroll-bar-width and buffer-display-count.
1426 Use Qstringp for default-directory, buffer-file-name,
1427 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1428 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1430 * data.c (store_symval_forwarding): Adjust to call the predicate.

1446 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1447 (make_gap_1): New function to adjust the gap of any buffer.
1448 * coding.c (coding_alloc_by_making_gap): Use it.
1449 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1450 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1452 2013-01-08 Juri Linkov <juri@jurta.org>

1466 2013-01-06 Chong Yidong <cyd@gnu.org>
1468 * keyboard.c (echo_add_char): New function, factored out from

1473 trailing dash is properly added.
1475 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1477 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1478 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1479 digits for buffer positions, before misalignment starts.
1480 Display "0" for integer "object" field.
1481 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1482 Display the newline glyph more unambiguously.
1484 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1486 * nsterm.m (ns_draw_underwave):
1487 * w32term.c (w32_draw_underwave):
1488 * xterm.c (x_draw_underwave): Make underwave look more triangular
1489 and also degrade gracefully for small fonts. (Bug#13000)
1491 * nsterm.m (ns_draw_text_decoration):
1492 * w32term.c (x_draw_glyph_string):
1493 * xterm.c (x_draw_glyph_string): Don't use previous underline
1494 thickness and position if previous underline type is underwave.
1496 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1498 * fileio.c (Ffile_acl): Undocument return format.
1500 2013-01-02 Glenn Morris <rgm@gnu.org>
1502 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
1504 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>

1511 * fringe.c (compute_fringe_widths):
1512 * lread.c (read_list):
1513 * minibuf.c (Ftry_completion):
1514 * term.c (tty_ins_del_lines):
1515 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1516 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1518 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1520 * w32.c (unsetenv): Set up the string passed to _putenv
1522 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1523 for the bug this caused.
1525 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1527 * coding.c (Qmac): Now static.
1529 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1531 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1532 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1536 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1537 Show all on TOOLBAR_TOP_WIDGET.
1538 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1539 by TOOLBAR_TOP_WIDGET.
1540 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1541 Check toolbar_is_packed.
1542 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1544 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1546 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1547 (xg_update_menubar): Update title only if
1548 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1549 (xg_update_submenu): Skip tearoff only if
1550 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1551 (xg_initialize): Initialize xg_detached_menus only if
1552 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1554 * xterm.h (struct x_output): Surround handlebox_widget with
1555 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1556 toolbar_in_hbox is bool.
1558 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1560 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1561 (LIBS_GNUSTEP): Define.
1562 (LIBES): Add $(LIBS_GNUSTEP).
1563 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1565 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1567 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1568 continuation glyph on a TTY with an indication of an empty line.
1571 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1573 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1574 file's SELinux context or ACLs successfully set, nil otherwise.
1576 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1578 * w32proc.c (reader_thread): Avoid passing NULL handles to
1579 SetEvent and WaitForSingleObject.
1581 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1583 Port EXTERNALLY_VISIBLE to Clang 3.2.
1584 * conf_post.h (__has_attribute): New macro.
1585 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1587 2012-12-27 Glenn Morris <rgm@gnu.org>
1589 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1590 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1592 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1594 * fileio.c (file_name_as_directory, directory_file_name):
1595 Accept an additional argument MULTIBYTE to indicate whether the input C
1596 came from a multibyte or a unibyte Lisp string; all callers
1597 adjusted. Don't assume the input string is always multibyte.
1599 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1600 don't ENCODE_FILE them, and return a unibyte string if the input
1602 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1603 don't assume the input strings will always be multibyte. If the
1604 input strings are multibyte, decode strings obtained from C
1607 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1609 * lisp.h (toplevel): Add two notices to the comment about
1610 defining a new Lisp data type.

1614 * alloc.c (valid_lisp_object_p): Adjust comment.
1616 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1618 * keyboard.c (record_asynch_buffer_change): Initialize an event
1619 only if it's really needed.
1620 * frame.h (enum output_method): Remove output_mac member since
1621 it's a leftover from the deleted code.
1622 * frame.c (Fframep): Adjust user here ...
1623 * terminal.c (Fterminal_live_p): ... and here.
1624 * coding.c (Qmac): Now here because it's only used to denote
1625 end-of-line encoding type.
1626 (syms_of_coding): DEFSYM it.
1627 * frame.h (Qmac): Remove duplicated declaration.
1629 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1631 * window.c (select_window_1): Now static, since it's used only here.
1633 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1635 * window.c (window_body_cols): Subtract display margins from the
1636 window body width on TTYs as well. See
1637 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1638 for the original report.
1640 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1642 * xdisp.c (redisplay_window): Remove inner local variable
1643 because the outer shadowed one has the same meaning.
1644 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1646 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1647 (xg_create_tool_bar): Adjust users.
1649 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1651 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1652 * buffer.c (Fget_buffer_create): Use it to set compact field of
1653 struct buffer_text to avoid accessing an uninitialized value
1654 when compact_buffer is called for the first time.
1655 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1656 (Fset_buffer_modified_p): Use buffer_window_count to check
1657 whether the buffer is displayed in some window.
1658 * xdisp.c (message_dolog): Likewise.
1660 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1662 * w32.c (acl_set_file): If setting the file security descriptor
1663 fails, and the new DACL is identical to the existing one, silently
1664 return success. This fixes problems for users backing up their
1665 own files without having the necessary privileges for setting
1666 security descriptors.
1668 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1670 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1671 after WaitForSingleObject returns normally. This expedites reader
1672 thread shutdown when delete_child triggers it.
1673 (reap_subprocess): More accurate commentary for why we call
1674 delete_child only when cp->fd is negative.
1676 * w32.c (sys_close): Do not call delete_child on a subprocess
1677 whose handle is not yet closed. Instead, set its file descriptor
1678 to a negative value, so that reap_subprocess will call
1679 delete_child on that subprocess when its SIGCHLD arrives.
1680 This avoids closing handles used for communications between sys_select
1681 and reader_thread, which doesn't give sys_select a chance to
1682 notice that the process exited and invoke the SIGCHLD handler for
1685 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1687 * nsfns.m (Fns_do_applescript): Run event loop until script has
1688 been executed (Bug#12969).

1694 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1696 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1698 * w32term.c (w32fullscreen_hook): New function.
1699 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1701 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1703 * fileio.c (Finsert_file_contents): Doc fix.
1705 * w32proc.c (new_child, delete_child, find_child_pid): For a
1706 subprocess, consider its slot being in use as long as its process
1707 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1708 slot when a new process is started immediately after killing
1709 another one, without waiting enough time for the first process to
1710 be reaped and resources allocated for it be orderly freed.
1712 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1714 2012-12-21 Chong Yidong <cyd@gnu.org>
1716 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1718 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1720 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1722 * w32.c (get_name_and_id): Always pass NULL as the first argument
1723 of lookup_account_sid. Avoids crashes with UNC file names that
1724 refer to DFS domains, not to specific machine names. (Bug#12621)
1725 Remove now unused argument FNAME; all callers changed.
1726 (get_file_owner_and_group): Remove now unused argument FNAME; all
1729 2012-12-21 Chong Yidong <cyd@gnu.org>
1731 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1732 error for invalid chars, don't check for a nil return value.
1734 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1736 Avoid calls to CHAR_TO_BYTE if byte position is known.
1737 * editfns.c (make_buffer_string_both): Use move_gap_both.
1738 (Fbuffer_string): Use make_buffer_string_both.

1741 (buf_bytepos_to_charpos): Likewise.
1742 (charpos_to_bytepos): Remove.
1743 * fileio.c (Finsert_file_contents): Use move_gap_both.
1744 * search.c (Freplace_match): Likewise.
1745 * process.c (process_send_region): Likewise. Use convenient
1746 names for byte positions.
1747 * lisp.h (charpos_to_bytepos): Remove prototype.
1748 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1749 * insdel.c (move_gap): Likewise.

1757 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1758 (redisplay_internal): Don't bother selecting the frame to get the
1759 proper value of frame-local variables (bug#13225).
1761 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1763 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1764 Rename 4th argument since it may be buffer or string. Adjust comment.
1765 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1767 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1769 * coding.c (Fdetect_coding_region): Do not check start and end with
1770 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1771 (code_convert_region): Likewise.
1773 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1775 * w32.c (acl_get_file, acl_set_file): Run the file name through
1776 map_w32_filename, and resolve any symlinks in the file name, like
1778 (acl_set_file): Call revert_to_self, if any privileges were
1781 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1783 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1784 ($(BLD)/w32.$(O)): Update dependencies.
1786 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1788 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1789 propagate redisplay's scrolling (if any) to the right window.
1790 (redisplay_internal): Use ensure_selected_frame.
1791 (display_mode_lines): Complete last fix.
1792 * window.c (select_window_1): New func, extracted from select_window.
1793 (select_window): Use it.
1794 * window.h (select_window_1): Declare.

1820 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1822 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1823 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1824 for some of that bug's symptoms can now cause Emacs to abort.
1825 Remove the workaround.
1826 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1827 The bug that caused SIGCHLD to get lost has been fixed, and the
1828 workaround for it can now cause Emacs to abort.
1830 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1832 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1833 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1834 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1878 delete the file, record it as pending deletion when the subprocess

1889 Fix permissions bugs with setgid directories etc. (Bug#13125)
1890 * dired.c (Ffile_attributes): Return t as the 9th attribute,

1893 file-ownership-preserved-p instead, with its new group arg.
1894 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1903 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1904 try to get accurate owner and group information from NT file
1905 security APIs. This is to make most callers of 'stat' and
1906 'lstat', which don't need that information, much faster.
1908 * dired.c (Ffile_attributes) [WINDOWSNT]:
1909 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1910 owner and group information from 'lstat'.
1912 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1914 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1915 as that confuses set-auto-coding, so insist on the head-read
1916 returning the full 1024 bytes. Let lseek compute the tail offset;
1917 less work for us. Do not ignore I/O errors when reading the tail.

1920 (init_iterator): Hoist assignment out of if-expression.
1921 (markpos_of_region): Callers now test for sign, not for -1.

1944 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1946 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1947 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1948 Remove unnecessary S_ISLNK test, as (contra the comments) this
1949 function can't copy symlinks. Improve quality of error message
1950 when attempting to copy files that are neither regular files nor

1969 * inotify.c (inotify_callback): Generate an Emacs event for every
1970 incoming inotify event.
1972 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1974 * xdisp.c (handle_face_prop): Fix logic of computing
1975 it->start_of_box_run_p.
1976 (append_space_for_newline): If the glyph row is R2L, reset the
1977 iterator's end_of_box_run_p flag before prepending the space glyph.
1978 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1979 iterator's start_of_box_run_p flag before prepending the stretch.

1982 left_box_line_p and right_box_line_p flags of the glyph for R2L
1983 glyph rows. (Bug#13011)

1998 encoded_file_name, which is what it is.
2000 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

2029 * w32fns.c (cache_system_info): Initialize the global hinst
2030 variable here so various initialization calls DTRT.
2032 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2033 (hinst): Remove unneeded extern declaration.
2034 (_start): Remove initialization of above variables; remove
2035 initialization of hinst, as cache_system_info now does that.

2254 * frame.c (make_frame): Do not set window's buffer to t.
2255 * window.c (Fsplit_window_internal): Likewise. Previously it was

2292 (call_process_kill): Use it.
2293 This does not change call_process_kill's behavior.
2294 * process.c (Fdelete_process): Use record_kill_process to fix a
2295 race condition that could cause Emacs to lose track of a child.

2306 fails, signal an error instead of continuing with an empty
2308 Encode expanded temp file pattern before passing it to mkstemp or
2311 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2312 Encode the file name before passing it to dostounix_filename, in
2313 case it will downcase it (under w32-downcase-file-names).
2316 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2318 Minor call-process cleanups.
2319 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2320 at the same time as other platforms, to simplify analysis.
2321 No need for fd0_volatile since we have synch_process_fd.

2344 Don't let call-process be a zombie factory (Bug#12980).
2345 Fixing this bug required some cleanup of the signal-handling code.
2346 As a side effect, this change also fixes a longstanding rare race
2347 condition whereby Emacs could mistakenly kill unrelated processes,
2348 and it fixes a bug where a second C-g does not kill a recalcitrant
2349 synchronous process in GNU/Linux and similar platforms.
2350 The patch should also fix the last vestiges of Bug#9488,
2351 a bug which has mostly been fixed on the trunk by other changes.
2352 * callproc.c, process.h (synch_process_alive, synch_process_death)
2353 (synch_process_termsig, sync_process_retcode):
2354 Remove. All uses removed, to simplify analysis and so that
2355 less consing is done inside critical sections.
2356 * callproc.c (call_process_exited): Remove. All uses replaced
2357 with !synch_process_pid.
2358 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2359 These take the role of what used to be in unwind-protect arg.
2361 (block_child_signal, unblock_child_signal):
2362 New functions, to avoid races that could kill innocent-victim processes.
2363 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2364 (call_process_kill): Record killed processes as deleted, so that
2365 zombies do not clutter up the system. Do this inside a critical
2366 section, to avoid a race that would allow the clutter.
2367 (call_process_cleanup): Fix code so that the second C-g works again
2368 on common platforms such as GNU/Linux.
2369 (Fcall_process): Create the child process in a critical section,
2370 to fix a race condition. If creating an asynchronous process,
2371 record it as deleted so that zombies do not clutter up the system.
2372 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2373 light of these changes. Omit unnecessary call to emacs_close
2374 before failure, as the unwind-protect code does that.
2375 * callproc.c (call_process_cleanup):
2376 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2377 * process.c (record_deleted_pid): New function, containing
2378 code refactored out of Fdelete_process.
2379 (Fdelete_process): Use it.
2380 (process_status_retrieved): Remove. All callers changed to use
2381 child_status_change.
2382 (record_child_status_change): Remove, folding its contents into ...
2383 (handle_child_signal): ... this signal handler. Now, this
2384 function is purely a handler for SIGCHLD, and is not called after
2385 a synchronous waitpid returns; the synchronous code is moved to
2386 wait_for_termination. There is no need to worry about reaping
2387 more than one child now.
2388 * sysdep.c (get_child_status, child_status_changed): New functions.
2389 (wait_for_termination): Now takes int * status and bool
2390 interruptible arguments, too. Do not record child status change;
2391 that's now the caller's responsibility. All callers changed.
2392 Reimplement in terms of get_child_status.
2393 (wait_for_termination_1, interruptible_wait_for_termination):
2394 Remove. All callers changed to use wait_for_termination.
2395 * syswait.h: Include <stdbool.h>, for bool.
2396 (record_child_status_change, interruptible_wait_for_termination):
2398 (record_deleted_pid, child_status_changed): New decls.
2399 (wait_for_termination): Adjust to API changes noted above.
2401 * bytecode.c, lisp.h (Qbytecode): Remove.
2402 No longer needed after 2012-11-20 interactive-p changes.
2404 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2406 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2407 the scroll margin, move point outside the margin. (Bug#13055)
2409 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2411 * gtkutil.c (my_log_handler): New function.
2412 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2414 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2416 * lisp.h (modify_region): Rename to...
2417 (modify_region_1): ...new prototype.
2418 * textprop.c (modify_region): Now static. Adjust users.
2419 * insdel.c (modify_region): Rename to...
2420 (modify_region_1): ...new function to work with current buffer.
2421 Adjust comment and users. Use true and false for booleans.
2423 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2425 * alloc.c (free_save_value): New function.
2426 (safe_alloca_unwind): Use it.
2427 * lisp.h (free_save_value): New prototype.
2428 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2430 (save_excursion_restore): Adjust to match saved data structure.
2431 Use free_save_value to offload some work from GC. Drop obsolete
2434 2012-12-03 Chong Yidong <cyd@gnu.org>
2436 * fileio.c (Vauto_save_list_file_name): Doc fix.
2438 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2440 * w32fns.c: Remove prototype of atof.
2441 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2443 (file_dialog_callback): Make it UINT_PTR.
2445 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2448 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2449 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2452 2012-12-03 Glenn Morris <rgm@gnu.org>
2454 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2456 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2458 Fix xpalloc confusion after memory is exhausted.
2459 * alloc.c (xpalloc): Comment fix.
2460 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2461 and signals an error, do not clear charset_table_size, as
2462 charset_table is still valid.
2463 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2465 Use execve to avoid need to munge environ (Bug#13054).
2466 * callproc.c (Fcall_process):
2467 * process.c (create_process):
2468 Don't save and restore environ; no longer needed.
2469 * callproc.c (child_setup):
2470 Use execve, not execvp, to preserve environ.
2472 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2474 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2476 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2478 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2479 display for sliced images (Bug#10500).
2481 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2483 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2485 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2486 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2488 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2490 * xdisp.c (window_outdated): Remove eassert since it hits
2491 some suspicious corner cases (see Bug#13007 and Bug#13012).
2492 (mode_line_update_needed): New function.
2493 (redisplay_internal, redisplay_window): Use it.
2494 (ensure_selected_frame): New function.
2495 (redisplay_internal, unwind_redisplay): Use it.
2496 (redisplay_internal): Move comment about buffer_shared...
2497 (buffer_shared_and_changed): ...near to its real use.
2499 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2501 * callproc.c (Fcall_process): Don't misreport vfork failure.
2503 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2505 * callproc.c (Fcall_process): Fix vfork portability problems.
2506 Do not assume that fd[0], count, filefd, and save_environ survive
2507 vfork. Fix bug whereby wrong errno value could be reported for
2508 pipe failure. Some minor cleanups, too, as follows. Move buf and
2509 bufsize to the context where they're needed. Change new_argv to
2510 be of type char **, as this is more convenient and avoids casts.
2511 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2512 Now local constants, not macros.
2514 2012-11-18 Kenichi Handa <handa@gnu.org>
2516 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2517 for the variable "f".
2519 2012-11-13 Kenichi Handa <handa@gnu.org>
2521 * font.c (font_unparse_xlfd): Exclude special characters from the
2522 generating XLFD name.
2524 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2526 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

2564 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2565 between bpos_covered and bpos_max. This fixes cursor display when
2566 several display strings follow each other.
2568 * .gdbinit (pgx): If the glyph's object is a string, display the
2569 pointer to string data, rather than the value of the string object
2570 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2572 * indent.c (Fvertical_motion): If the starting position is covered
2573 by a display string, return to one position before that, to avoid
2574 overshooting it inside move_it_to. (Bug#12930)
2576 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2595 of a literal "/". (Bug#12955)
2596 (gl-stamp): Invoke fc.exe directly, not through cmd.

2600 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2601 * dired.c: Assume HAVE_DIRENT_H.
2602 (NAMLEN): Remove, replacing with ...
2603 (dirent_namelen): New function. All uses changed. Use the GNU macro
2604 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2605 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2606 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2607 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2609 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2610 * ndir.h: Rename to ../nt/inc/dirent.h.
2611 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2612 Do not include <dirent.h>; no longer needed.
2613 * w32.c: Include <dirent.h> rather than "ndir.h".
2615 2012-11-23 Chong Yidong <cyd@gnu.org>
2617 * xftfont.c (xftfont_open): Remove duplicate assignment.
2619 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2621 * alloc.c (Fgarbage_collect): Unblock input after clearing
2622 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2623 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2624 * msdos.c (IT_frame_up_to_date): Use it here...
2625 * w32term.c (w32_frame_up_to_date): ...here...
2626 * xterm.c (XTframe_up_to_date): ...and here...
2627 * nsterm.m (ns_frame_up_to_date): ...but not here.

2641 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2643 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2644 with Windows system header.

2669 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2671 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2672 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2673 Define for the MSVC compiler.
2675 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2677 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2678 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to

2680 dostounix_filename assumes it gets a unibyte string.
2681 Reported by Michel de Ruiter <michel@sentient.nl>, see

2730 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2732 * w32select.c: Include w32common.h before w32term.h, so that
2733 windows.h gets included before w32term.h uses some of its
2734 features, see below.
2736 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2738 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2752 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2754 * w32proc.c (waitpid): Remove unused label get_result.
2756 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2758 * makefile.w32-in (SYSWAIT_H): New macro.

2766 * emacs.c, term.c (O_RDWR): Remove.
2767 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2768 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2769 * nsterm.m: Assume <fcntl.h> exists.
2770 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2771 (create_pty, Fmake_network_process, server_accept_connection)
2772 (wait_reading_process_output, init_process_emacs):
2774 (wait_reading_process_output): Put in a special case for WINDOWSNT
2775 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2776 It's not clear this is needed, but it's a more-conservative change.
2777 (create_process): Assume FD_CLOEXEC.
2778 (create_process, create_pty): Assume O_NOCTTY.
2779 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2780 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2781 Omit if not DOS_NT, since F_GETFL is not defined there.
2782 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2783 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2785 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2786 lack it, since gnulib guarantees this.
2787 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2789 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2791 * w32.c (faccessat): Pretend that directories have the execute bit
2792 set. Emacs expects that, e.g., in files.el:cd-absolute.
2794 * w32proc.c (create_child): Don't clip the PID of the child
2795 process to fit into an Emacs integer, as this is no longer a
2797 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2798 reaping only the process specified by PID argument, if that is
2799 positive. Use PID instead of dead_child to know which process to
2800 reap. Wait for the child to die only if WNOHANG is not in
2802 (sys_select): Don't set dead_child.
2804 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2805 as it is no longer needed.
2807 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2809 (record_child_status_change): Remove the setting of
2810 record_at_most_one_child for the !WNOHANG case.
2812 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2814 Fix problems in ns port found by static checking.
2815 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2816 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2817 not to process group.
2818 (ns_select): Use emacs_write, not write, as that's more robust
2819 in the presence of signals.
2820 (fd_handler:): Check for read errors.
2822 2012-11-16 Glenn Morris <rgm@gnu.org>
2824 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2826 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2828 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2830 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2832 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2833 use the same value of thread handle.
2834 (start_timer_thread): If the timer thread exited (due to error),
2835 clean up by closing the two handles it used. Duplicate the caller
2836 thread's handle here, so it gets duplicated only once, when
2837 launching the timer thread. Set priority of the timer thread, not
2839 (getitimer): Don't duplicate the caller thread's handle here.
2842 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2844 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2847 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2849 Remove no-longer-used pty_max_bytes variable.
2850 * process.c (pty_max_bytes): Remove; unused.
2851 (send_process): Do not set it.
2853 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2855 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2856 Update dependencies.
2858 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2860 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2861 This follows up on the 2012-09-29 patch that removed indirection
2862 for the 'function' field. Reported by Sergey Vinokurov in
2863 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2865 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2867 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2868 different name, as the MS runtime does not have such a function,
2869 and probably never will.) All callers changed. Ignore DIRFD
2870 value if PATH is an absolute file name, to match Posix spec
2871 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2874 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2876 * xdisp.c (echo_area_display, redisplay_internal):
2877 Omit redundant check whether frame_garbaged is set.
2879 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2881 Use faccessat, not access, when checking file permissions (Bug#12632).
2882 This fixes a bug that has been present in Emacs since its creation.
2883 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2884 which must set some sort of record. (Torek's bug report was against
2885 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2886 same common flaw.) See Torek's Usenet posting
2887 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2888 Posted: Fri Apr 8 14:18:56 1983.
2889 * Makefile.in (LIB_EACCESS): New macro.
2891 * callproc.c (init_callproc):
2892 * charset.c (init_charset):
2893 * fileio.c (check_existing, check_executable, check_writable)
2895 * lread.c (openp, load_path_check):
2896 * process.c (allocate_pty):
2898 Use effective UID when checking permissions, not real UID.
2899 * callproc.c (init_callproc):
2900 * charset.c (init_charset):
2901 * lread.c (load_path_check, init_lread):
2902 Test whether directories are accessible, not merely whether they exist.
2903 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2904 * fileio.c (check_existing, check_executable, check_writable)
2906 Use symbolic names instead of integers for the flags, as they're
2908 (check_writable): New arg AMODE. All uses changed.
2909 Set errno on failure.
2910 (Ffile_readable_p): Use faccessat, not stat + open + close.
2911 (Ffile_writable_p): No need to call check_existing + check_writable.
2912 Just call check_writable and then look at errno. This saves a syscall.
2913 dir should never be nil; replace an unnecessary runtime check
2914 with an eassert. When checking the parent directory of a nonexistent
2915 file, check that the directory is searchable as well as writable, as
2916 we can't create files in unsearchable directories.
2917 (file_directory_p): New function, which uses 'stat' on most platforms
2918 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2919 (Ffile_directory_p, Fset_file_times): Use it.
2920 (file_accessible_directory_p): New function, which uses a single
2921 syscall for efficiency.
2922 (Ffile_accessible_directory_p): Use it.
2923 * xrdb.c (file_p): Use file_directory_p.
2924 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2925 * lread.c (openp): When opening a file, use fstat rather than
2926 stat, as that avoids a permissions race. When not opening a file,
2927 use file_directory_p rather than stat.
2928 (dir_warning): First arg is now a usage string, not a format.
2929 Use errno. All uses changed.
2930 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2931 that merely introduced a race.
2932 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2933 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2934 and similarly for the other O_* flags.
2935 * w32.c (sys_faccessat): Rename from sys_access and switch to
2936 faccessat's API. All uses changed.
2937 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2938 (magic_db): Rename from magic_file_p.
2939 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2940 char *, so that we don't have to test for file existence
2941 separately from opening the file for reading. This removes a race
2942 fixes a permission-checking problem, and simplifies the code.
2944 (file_p): Remove; no longer needed.
2946 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2948 Omit glyphs initialization at startup.
2949 * dispnew.c (glyphs_initialized_initially_p): Remove.
2950 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2951 (Fredraw_frame): Move actual code from here...
2952 (redraw_frame): ...to here. Add eassert. Adjust comment.
2953 (Fredraw_display): Use redraw_frame.
2954 * xdisp.c (clear_garbaged_frames): Likewise.
2956 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2958 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2959 passed to pint2str and pint2hrstr to be at most the size of the
2960 frame's decode_mode_spec_buffer. This avoids crashes with very
2961 large values of FIELD_WIDTH argument to decode_mode_spec.
2964 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2966 Fix a race with verify-visited-file-modtime (Bug#12863).
2967 Since at least 1991 Emacs has ignored an mtime difference of no
2968 more than one second, but my guess is that this was to work around
2969 file system bugs that were fixed long ago. Since the race is
2970 causing problems now, let's remove that code.
2971 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2972 whose time stamp is off by no more than a second. Insist that the
2973 file time stamps match exactly.
2975 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2977 * frame.h (struct frame): Convert external_tool_bar member to
2978 1-bit unsigned bitfield.
2979 * termhooks.h (struct terminal): Remove mouse_moved member since
2980 all users are long dead. Adjust comment on mouse_position_hook.
2982 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2984 Simplify by using FOR_EACH_FRAME here and there.
2985 * frame.c (next_frame, prev_frame, other_visible_frames)
2986 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2987 * w32term.c (x_window_to_scroll_bar): Likewise.
2988 * window.c (window_list): Likewise.
2989 * xdisp.c (x_consider_frame_title): Likewise.
2990 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2991 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2992 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2993 * xmenu.c (menubar_id_to_frame): Likewise.
2994 * xselect.c (frame_for_x_selection): Likewise.
2995 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2996 (x_window_to_menu_bar): Likewise.
2997 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2999 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3001 * data.c (Qdefalias_fset_function): Now static.
3003 Another tweak to vectorlike_header change.
3004 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3005 Remove, and replace all uses with ...
3006 (next_in_free_list, set_next_in_free_list):
3007 New functions, which respect C's aliasing rules better.
3009 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3011 * window.c (list4i): Rename from 'quad'. All uses changed.
3012 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3014 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3016 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3017 warning about mixing declarations and code in ISO C90.
3019 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3021 * window.c (Fsplit_window_internal): Set combination limit of
3022 new parent window to t iff Vwindow_combination_limit is t;
3023 fixing a regression introduced with the change from 2012-09-22.
3024 (Fset_window_combination_limit): Fix doc-string.
3026 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3028 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3029 amount when the scroll margins are too large. When scrolling
3030 backwards in the buffer, give up if cannot reach point or the
3031 scroll margin within a reasonable number of screen lines.
3032 Fixes point position in window under scroll-up/down-aggressively when
3033 point is positioned many lines beyond the window top/bottom.
3036 * ralloc.c (relinquish): If real_morecore fails to return memory
3037 to the system, don't crash; instead, leave the last heap
3038 unchanged and return. (Bug#12774)
3040 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3042 * lisp.h (AUTOLOADP): New macro.
3043 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3044 * data.c (Ffset): Remove special ad-advice-info handling.
3045 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3047 (Finteractive_form): Simplify.
3048 (Fquo): Don't insist on having at least 2 arguments.
3049 (Qdefalias_fset_function): New var.
3051 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3053 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3055 * nsfont.m (Qcondensed, Qexpanded): New variables.
3056 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3057 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3059 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3061 Fix recently introduced crash on MS-Windows (Bug#12839).
3062 * w32term.h (struct scroll_bar): Use convenient header.
3063 (SCROLL_BAR_VEC_SIZE): Remove.
3064 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3066 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3068 Tweak last vectorlike_header change.
3069 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3070 vectorlike object on the free list. This is introduced to avoid
3071 some (but not all) pointer casting and aliasing problems, see
3072 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3073 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3075 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3077 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3079 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3080 been removed, so remove them here also.
3082 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3084 * doc.c (Fdocumentation): Handle new property
3085 dynamic-docstring-function to replace the old ad-advice-info.
3087 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3089 * fns.c (Qeql, hashtest_eq): Now static.
3091 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3093 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3094 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3095 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3096 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3098 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3100 Use same hash function for hashfn_profiler as for hash_string etc.
3101 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3102 * lisp.h (sxhash_combine): New inline function, with the contents
3103 of the old SXHASH_COMBINE.
3104 * profiler.c (hashfn_profiler): Use it, instead of having a
3105 special hash function containing a comparison that always yields 1.
3107 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3109 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3110 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3111 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3114 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3116 * image.c (xpm_make_color_table_h): Fix compiler error because
3117 make_hash_table changed.
3119 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3121 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3123 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3125 Use ad-hoc comparison function for the profiler's hash-tables.
3126 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3127 (make_log): Use them.
3128 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3129 call Fequal any more.
3130 (Ffunction_equal): New function.
3131 (cmpfn_profiler, hashfn_profiler): New functions.
3132 (syms_of_profiler): Initialize them.
3133 * lisp.h (struct hash_table_test): New struct.

3138 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3139 (hash_lookup, hash_remove_from_table): Move assertion checking of
3140 hashfn result here. Check hash-equality before calling cmpfn.
3141 (Fmake_hash_table): Adjust call to make_hash_table.
3142 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3143 (syms_of_fns): Initialize them.

3146 * category.c (hash_get_category_set): Adjust call to make_hash_table.
3147 * print.c (print_object): Adjust to new hash-table struct.
3148 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
3150 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3152 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3153 value of w32-scroll-lock-modifier is neither nil nor one of the
3154 known key modifiers. (Bug#12806)
3156 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3158 Shrink struct vectorlike_header to the only size field.
3159 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3161 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3162 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3163 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3164 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3165 information from the vector header. Adjust comment.
3166 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
3167 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
3169 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
3170 (struct vectorlike_header): Remove next member. Adjust comment.

3173 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
3174 (sweep_string, lisp_malloc): Remove useless prototypes.
3175 (enum mem_type): Adjust comment.
3176 (NEXT_IN_FREE_LIST): New macro.
3177 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3178 (Fmake_bool_vector): Likewise.
3179 (struct large_vector): New type to represent allocation unit for
3180 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3181 (large_vectors): Change type to struct large_vector.
3182 (allocate_vector_from_block): Simplify.
3183 (PSEUDOVECTOR_NBYTES): Replace with...
3184 (vector_nbytes): ...new function. Adjust users.
3185 (sweep_vectors): Adjust processing of large vectors.
3186 (allocate_vectorlike): Likewise.
3187 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3188 Add easserts. Adjust XSETPVECTYPESIZE usage.
3189 (allocate_buffer): Use BUFFER_PVEC_INIT.
3190 (live_vector_p): Adjust to match large vector.
3191 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3192 * buffer.h (struct buffer): Add next member.
3193 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3195 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3196 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3197 (copy_hash_table): Adjust to match vector header change.
3198 * lread.c (defsubr): Use XSETPVECTYPE.
3199 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3200 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3201 (xvecsize): New command.
3203 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3205 * keyboard.c (event_to_kboard): Do not dereference
3206 frame_or_window field of SELECTION_REQUEST_EVENT
3207 and SELECTION_CLEAR_EVENT events (Bug#12814).
3208 * xterm.h (struct selection_input_event): Adjust comment.
3210 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3212 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3213 such as Scroll Lock, if the respective keys are treated as
3214 function keys, not as modifiers. This avoids destroying non-ASCII
3215 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3217 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3219 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3221 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3223 Restore some duplicate definitions (Bug#12814).
3224 This undoes part of the 2012-11-03 changes. Some people build
3225 with plain -g rather than with -g3, and they need the duplicate
3226 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3227 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3228 Define as macros, as well as as enums or as constants.
3230 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3232 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3233 to keypad keys (Bug#12816).
3235 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3237 Minor adjustments of recently-changed frame functions.
3238 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3239 known to be a frame (we're in the FRAMEP branch).
3240 * lisp.h (Qframep): Remove decl. frame.h declares this.
3241 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3242 since they're meant for Lisp fixnum values.
3244 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3246 * window.c (Fwindow_combination_limit): Revert to the only
3247 required argument and adjust docstring as suggested in
3248 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3249 by Martin Rudalics <rudalics@gmx.at>.
3251 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3253 Widely used frame validity and checking functions.
3254 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3255 * frame.c (decode_live_frame, decode_any_frame): New functions.
3256 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3257 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3258 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

3265 (frame_buffer_list, frame_buffer_predicate): Remove.
3266 * lisp.h (frame_buffer_predicate): Remove prototype.
3267 * buffer.c (Fother_buffer): Use decode_any_frame.
3268 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3269 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3270 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3271 (Fclose_font, Ffont_info): Use decode_live_frame.
3272 * fontset.c (check_fontset_name): Likewise.
3273 * terminal.c (Fframe_terminal): Likewise.
3274 * w32fns.c (check_x_frame): Likewise.
3275 * window.c (Fminibuffer_window, Fwindow_at)
3276 (Fcurrent_window_configuration): Likewise.

3280 * xfaces.c (frame_or_selected_frame): Remove.
3281 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3282 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3283 (Fframe_face_alist): Use decode_live_frame.
3284 * xfns.c (check_x_frame): Likewise.
3286 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3288 * window.c (quad): New function.
3289 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3290 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3291 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)

3293 (Fwindow_fringes): Use list3.
3294 (Fwindow_scroll_bars): Use list4.
3295 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3296 (Fwindow_combination_limit): Allow zero number of arguments.
3298 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3300 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3302 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3303 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3304 file descriptor 2 for standard error. (Bug#12805)
3306 2012-11-05 Chong Yidong <cyd@gnu.org>
3308 * process.c (wait_reading_process_output): Revert previous change.
3310 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3312 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3313 This removes code that has been obsolete since around 1990.
3314 * callproc.c (Fcall_process):
3316 * process.c (create_process):
3317 * term.c (dissociate_if_controlling_tty):
3318 Assume setsid exists.
3319 * callproc.c (child_setup): Assume setpgid exists and behaves as
3320 per POSIX.1-1988 or later.
3321 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3322 * emacs.c (shut_down_emacs):
3323 * sysdep.c (sys_suspend, init_foreground_group):
3324 Assume getpgrp behaves as per POSIX.1-1998 or later.
3325 * msdos.c (setpgrp): Remove.
3326 (tcgetpgrp, setpgid, setsid): New functions.
3327 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3328 * term.c (no_controlling_tty): Remove; unused.
3329 * w32proc.c (setpgrp): Remove.
3330 (setsid, tcgetpgrp): New functions.
3332 Simplify by assuming __fpending.
3333 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3334 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3335 Do not assume that __fpending's result fits in int.
3337 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3339 Remove EMACS_OUTQSIZE+sleep hack.
3340 * dispnew.c (update_frame_1): Remove hack for terminals slower
3341 than 2400 bps, which throttled Emacs by having it sleep.
3342 This code hasn't worked since at least 2007, when the multi-tty stuff
3343 was added, and anyway those old terminals are long dead.
3344 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3345 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3347 Fix data-loss with --version (Bug#9574).
3348 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3349 as we can't assume that emacs_strerror is initialized, and strerror
3350 is good enough here.
3351 (main): Invoke atexit earlier, to catch earlier instances of
3352 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3354 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3356 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3357 (keyDown): Remap keypad keys to X11 virtual key codes.
3359 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3361 Fix data-loss with --batch (Bug#9574).
3362 * emacs.c: Include <close-stream.h>.
3363 (close_output_streams): New function.
3364 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3365 and handles errors appropriately.
3366 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3369 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3370 The symptom is a diagnostic "GLib-WARNING **: In call to
3371 g_spawn_sync(), exit status of a child process was requested but
3372 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3373 waitpid(), so exit status can't be returned." The diagnostic
3374 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3375 The real bug is a race condition between Emacs and glib: Emacs
3376 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3377 so that glib can't find it. Work around the bug by invoking
3378 waitpid only on subprocesses that Emacs itself creates.
3379 * process.c (create_process, record_child_status_change):
3380 Don't use special value -1 in pid field, as the caller now must
3381 know the pid rather than having the callee infer it.
3382 The inference was sometimes incorrect anyway, due to another race.
3383 (create_process): Set new 'alive' member if child is created.
3384 (process_status_retrieved): New function.
3385 (record_child_status_change): Use it.
3386 Accept negative 1st argument, which means to wait for the
3387 processes that Emacs already knows about. Move special-case code
3388 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3389 processes that have already been waited for, by testing and
3390 clearing new 'alive' member.
3391 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3392 now does this internally.
3393 (handle_child_signal): Let record_child_status_change do all
3394 the work, since we do not want to reap all exited child processes,
3395 only the child processes that Emacs itself created.
3396 * process.h (Lisp_Process): New boolean member 'alive'.
3398 Omit duplicate definitions no longer needed with gcc -g3.
3399 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3400 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3401 Define only as macros. There's no longer any need to also define
3402 these symbols as enums or as constants, since we now assume
3403 gcc -g3 when debugging.
3405 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3407 * lisp.mk: Adjust comments to the fact that term/internal is now
3408 loaded from loadup.el.
3410 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3411 (msdos_fatal_signal): New function.
3412 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3415 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3416 for GCC versions before 4.
3417 (emacs_raise): Define to call msdos_fatal_signal.
3419 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3420 iterator when starting in the middle of a display or overlay
3423 2012-11-03 Chong Yidong <cyd@gnu.org>
3425 * process.c (wait_reading_process_output): Clean up the last
3428 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3430 * process.c (wait_reading_process_output): Avoid a race condition
3431 with SIGIO delivery (Bug#11536).
3433 2012-11-03 Chong Yidong <cyd@gnu.org>
3435 * buffer.c (cursor_type): Untabify docstring.
3437 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3439 * frame.h (struct frame): Drop can_have_scroll_bars member
3440 which is meaningless for a long time. Adjust comments.
3441 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3442 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3444 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3446 * window.c (decode_next_window_args): Update window arg after
3447 calling decode_live_window and so fix crash reported at
3448 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3449 by Juanma Barranquero <lekktu@gmail.com>.
3450 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3451 * font.c (Ffont_at): Likewise.
3453 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3455 * widget.c (resize_cb): New function.
3456 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3457 (EmacsFrameResize): Check if all is up to date before changing frame
3460 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3462 Implement backtrace output for fatal errors on MS-Windows.
3463 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3464 (BACKTRACE_LIMIT_MAX): New macro.
3465 (w32_backtrace): New function.
3466 (emacs_abort): Use w32_backtrace when the user chooses not to
3467 attach a debugger. Update the text of the abort dialog.
3469 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3471 Window-related stuff cleanup here and there.
3472 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3473 Use decode_any_window.
3474 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3475 * xdisp.c (Fformat_mode_line): Likewise.
3476 * font.c (Ffont_at): Use decode_live_window.
3477 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3478 * window.c (decode_next_window_args): Likewise.
3479 (decode_any_window): Remove static.
3480 * window.h (decode_any_window): Add prototype.
3481 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3482 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3485 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3487 Remove pad from struct input_event.
3488 * termhooks.h (struct input_event): Remove padding field.
3490 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3491 member is never cons for a long time. Adjust comment.
3492 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3493 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3494 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3495 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3497 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3499 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3501 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3503 Fix crash when using Emacs as commit editor for git (Bug#12697).
3504 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3505 and it is configured in conf_post.h.
3506 (Fcall_process): Don't invoke both setsid and setpgid; the former
3507 is enough, if it exists.
3508 * callproc.c (Fcall_process, child_setup):
3509 * process.c (create_process): Use setpgid.
3510 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3512 * dispnew.c (init_display): Initialize the foreground group
3513 if we are running a tty display.
3514 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3515 * lisp.h (init_foreground_group): New decl.
3516 * sysdep.c (inherited_pgroup): New static var.
3517 (init_foreground_group, tcsetpgrp_without_stopping)
3518 (narrow_foreground_group, widen_foreground_group): New functions.
3519 (init_sys_modes): Narrow foreground group.
3520 (reset_sys_modes): Widen foreground group.
3522 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3524 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3526 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3528 * minibuf.c (read_minibuf): Restore current buffer since
3529 choose_minibuf_frame calling Fset_frame_selected_window may
3530 change it (Bug#12766).
3532 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3534 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3536 2012-10-30 Kenichi Handa <handa@gnu.org>
3538 * font.c (Ffont_at): If WINDOW is specified and it is not
3539 displaying the current buffer, signal an error.
3541 2012-10-29 Daniel Colascione <dancol@dancol.org>
3543 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3544 In preparation for fixing bug#12739, move these functions from
3547 * coding.h, coding.c: ... to here, and compile them only when
3548 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3549 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3551 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3553 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3554 (timer_loop, getitimer, setitimer): Use it instead of
3555 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3557 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3560 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3562 * nsterm.m (NO_APPDEFINED_DATA): New define.
3563 (last_appdefined_event_data): New variable
3564 (last_appdefined_event): Remove.
3565 (ns_select): Initialize t from last_appdefined_event_data instead
3566 of [last_appdefined_event data1].
3567 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3568 remove last_appdefined_event (Bug#12698).
3570 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3572 * frame.c (x_set_font): Catch internal error.
3574 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3576 Avoid overflow in w32 implementation of interval timers.
3577 When possible, for ITIMER_PROF count only times the main thread
3579 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3580 'volatile ULONGLONG' types. All the other data which was
3581 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3582 (GetThreadTimes_Proc): New typedef.
3583 (w32_get_timer_time): New function, returns a suitable time value
3585 (timer_loop): Enter critical section when accessing ULONGLONG
3586 values of the itimer_data struct, as these accesses are no longer
3587 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3588 Remove unused variable.
3589 (init_timers): Initialize s_pfn_Get_Thread_Times.
3590 (start_timer_thread): Don't assign itimer->caller_thread here.
3591 (getitimer): Assign itimer->caller_thread here.
3592 (setitimer): Always call getitimer to get the value of ticks_now.
3593 (sys_spawnve): Avoid compiler warning about format mismatch.
3595 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3597 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3598 mouse movement events if the menu bar is active. This avoids
3599 producing a busy "hour-glass" cursor by Windows if the mouse
3600 pointer is positioned over a tooltip shown for some menu item.
3602 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3604 Don't assume process IDs fit in int.
3605 * emacs.c (shut_down_emacs) [!DOS_NT]:
3606 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3607 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3608 Use pid_t, not int, to store process IDs, as 'int'
3609 is not wide enough on a few platforms (e.g., AIX and IRIX).
3611 2012-10-23 Kenichi Handa <handa@gnu.org>
3613 The following change is to make face-font-rescale-alist work
3614 correctly for non-ASCII fonts.
3616 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3617 (font_open_for_lface): Handle Vface_font_rescale_alist.
3619 2012-10-23 Chong Yidong <cyd@gnu.org>
3621 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3623 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3625 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3627 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3629 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3632 2012-10-21 Glenn Morris <rgm@gnu.org>
3634 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3636 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3638 Port to OpenBSD 5.1.
3639 * frame.c (Fmouse_position, Fmouse_pixel_position):
3640 * xdisp.c (produce_stretch_glyph):
3641 Declare local vars only when they're needed.
3642 This is clearer and avoids a warning on OpenBSD about unused vars.
3643 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3644 This is safer, and avoids OpenBSD warnings about unused vars.
3645 * keyboard.c (record_menu_key): Remove unnecessary decl.
3646 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3647 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3648 as our definition clashes with OpenBSD's.
3649 * xfaces.c (load_face_colors, check_lface_attrs)
3650 (get_lface_attributes_no_remap, get_lface_attributes)
3651 (lface_fully_specified_p, x_supports_face_attributes_p)
3652 (tty_supports_face_attributes_p, face_fontset, realize_face)
3653 (realize_x_face, realize_tty_face):
3654 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3655 merely Lisp_Object *. This is more informative and avoids
3656 a warning on OpenBSD about accessing beyond an object's size.
3658 2012-10-20 Chong Yidong <cyd@gnu.org>
3660 * lread.c (Fload): Doc fix (Bug#12592).
3662 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3664 * font.c (Ffont_at): Fix previous change.
3666 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3668 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3669 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3672 * alloc.c (NSTATICS): Decrease to 0x800.
3674 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
3676 * fns.c (Fnreverse): Include the problem element when signaling an
3679 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
3681 * nsterm.m (ns_select): Check writefds before call to
3682 FD_ISSET (Bug#12668).
3684 2012-10-18 Daniel Colascione <dancol@dancol.org>
3686 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3687 (staticpro): If we run out of staticpro slots, die with an
3688 informative error instead of just calling emacs_abort.

3947 since unsigned is guaranteed to have that behavior and signed is not.
3948 (read_char): Use ptrdiff_t for string length.
3949 (get_input_pending): Remove first argument, since it was always
3950 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3951 and behave as if it had that value. Return new value of
3952 input_pending. All callers changed.
3953 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3954 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

4000 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4001 'is_tooltip_frame', to avoid confusion with its global namesake.
4003 2012-10-08 Daniel Colascione <dancol@dancol.org>
4005 * xdisp.c (start_hourglass): Call w32_note_current_window when
4006 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4007 build that caused Emacs to display the hourglass cursor forever.
4009 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4010 which is broken under remote desktop, calculate the number of
4011 colors available for a display based on the display's number of
4012 planes and number of bits per pixel per plane. (bug#10397).
4014 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4016 * nsfont.m (Vfonts_in_cache): New variable.

4051 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4052 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close

4077 Use `report_file_error' instead of `error' in order to better
4078 inform users of what went wrong. Increase NTGUI_UNICODE file
4079 dialog box file name length to 32k, the maximum allowed by the NT
4082 * w32common.h: New file.

4089 * unexw32.c, unexcw.c: Include w32common.h.
4091 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4092 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4093 to call syms_of_w32select.
4095 * cygw32.h: Remove obsolete EXFUN declarations.

4114 2012-10-08 Daniel Colascione <dancol@dancol.org>
4116 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4117 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

4121 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4122 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4123 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4124 now a supported configuration.
4126 * Makefile.in: consolidate image variables into LIBIMAGE; add
4127 W32_OBJ and W32_LIBS. Compile new files.
4130 (_DebPrint) declare tracing facility for W32 debugging. We need
4131 to unify tracing later.
4133 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4134 unconditional use of W32 Unicode functions. Cygwin runs only on
4135 100% Unicode operating systems.
4137 * cygw32.c: New file. Define Cygwin-specific facilities.
4138 (Fcygwin_convert_path_to_windows)
4139 (Fcygwin_convert_path_from_windows): New user functions for
4140 accessing Cygwin path-munging routines.
4142 * cygw32.h: New file.
4143 (WCSDATA, to_unicode, from_unicode): Define facilities for storing

4147 (w32_strerror): Just what it says on the tin.
4149 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4150 also run for Cygwin; both systems have the same problem with using
4151 GUI facilities in a forked child. Also call syms_of_cygw32,
4152 syms_of_w32select in correct places.
4154 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4155 needs fork-then-exec for daemon launching.
4157 * font.h: Include frame.h.
4159 * image.c: Use the image library cache machinery only when we're
4160 compiling for native WINDOWSNT; Cygwin can use shared libraries
4161 like any other Unixlike system.
4163 * keyboard.c: Clarify a comment regarding the input loop.
4165 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4166 functions directly instead of trying to detect at runtime that our
4167 host operating system supports them. We make this change for two
4168 reasons: Cygwin lacks support for the multibyte character
4169 conversion functions used by the legacy menu code, and Cygwin
4170 never needs to rely on non-Unicode APIs.
4172 * unexw32.c (hinst): Declare extern.
4174 * w32.c: Change header order;
4175 (w32_strerror): Move to w32fns.c because we need it for
4176 non-WINDOWSNT builds.
4178 * w32.h: Add #error macro to make sure we don't include w32.h for
4179 Cygwin builds. Remove w32select declarations.
4181 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4182 w32fns.c. w32console.c is WINDOWSNT-only.
4184 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4185 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4187 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4188 (w32_major_version, w32_minor_version, w32_build_number)
4189 (os_subtype, sound_type): Define here
4190 (w32_defined_color): Make color parameter const for consistency
4191 with other _defined_color functions.
4192 (w32_createwindow): Unconditionally call w32_init_class instead of
4193 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4194 through the code is complex and unnecessary because class
4195 registration is practically free.
4196 (w32_name_of_message): New EMACSDEBUG-only function.
4197 (Fset_message_beep): Move here
4198 (Fx_open_connection): Require that the display name for Windows be
4199 "w32" for consistency, emacsclient disambiguation, and maybe, one
4200 day, multi-window-system support.
4201 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4202 Cygwin files for W32 GUI facilities, since these clearly don't
4203 expect Cygwin names.
4204 (_DebPrint): Define.
4205 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4206 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4207 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4208 (w32_last_error): Remove.
4210 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4212 * w32heap.c (syspage_mask): Declare here.
4213 (cache_system_info): Remove.
4215 * w32inevt.c (faked_key): Define globally, not statically.
4216 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4217 (w32_console_toggle_lock_key): Move to w32fns.c.
4219 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4221 * w32proc.c (_DebPrint): Move to w32fns.c.
4222 * w32select.c: Include string.h, stdio.h for Cygwin.
4223 * w32select.h: New File.
4225 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4227 (w32_message_fd): New variable. Under Cygwin, holds the file
4228 descriptor the system used to tell us about pending thread
4231 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4232 that prevented compilation under non-WINDOWSNT systems.
4234 (w32_initialize): Open /dev/windows and assign it to
4235 w32_message_fd. Provide w32 feature.
4237 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4238 (WM_EMACS_INPUT_READY): add.
4239 (prepend_msg, w32_message_fd): Declare globally.
4242 (keyboard_handle): Use only when WINDOWSNT.
4243 (notify_msg_ready): New function. Posts a message to the main
4244 thread's message queue under CYGWIN, which wakes up the main
4245 thread from select(2) by making the /dev/windows file descriptor
4246 ready. Under WINDOWSNT, it sets an event the same way the old
4249 (post, prepend_msg): Actually call notify_msg_ready instead of
4250 setting the input event directly.
4252 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4254 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4255 but it still has blocs in it, don't return it to the system,
4256 instead of aborting. (Bug#12402)
4258 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4260 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4262 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4263 MAC_OS_X_VERSION_10_6.
4264 (syms_of_nsterm): Remove comment about Panther and above for
4266 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4267 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4268 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4270 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4271 MAC_OS_X_VERSION_10_4.
4273 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4274 MAC_OS_X_VERSION_10_2.
4276 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4278 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4279 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4281 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4282 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4283 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4284 Remove ns_in_resize check.
4285 (ns_clear_frame_area): Remove resize handle code.
4287 * nsfns.m (ns_in_resize): Remove.
4288 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4289 Remove ns_in_resize check.
4291 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4293 Improve sys_siglist detection.
4294 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4295 defined as a macro, as is done in Solaris.
4296 (sys_siglist_entries): New macro.
4297 (save_strsignal): Use it.
4298 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4299 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4301 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4303 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4304 fullscreen/Fullscreen.
4306 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4307 tobar_height is new.
4309 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4310 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4311 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4312 (windowDidResize:): Check for correct window if old style fullscreen.
4313 Capitalize word in comment. Remove incorrect comment.
4314 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4315 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4316 error in drawing background.
4317 (toggleFullScreen:): Remove comment. Rearrange calls.
4318 Set toolbar values to zero, save old height in tobar_height.
4319 Restore tool bar height when leaving fullscreen.
4320 (canBecomeMainWindow): New function.
4322 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4324 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4326 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4328 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4330 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4331 that time stamps of directories could also be changed.
4332 Don't request the too broad GENERIC_WRITE, only the more restrictive
4333 FILE_WRITE_ATTRIBUTES access rights.
4335 * fileio.c (Fset_file_times): Special-case ignoring errors for
4336 directories only on MSDOS, not on MS-Windows.
4338 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4340 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4342 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4344 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4345 see whether CreateFile failed.
4347 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4349 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4350 to avoid similar races.
4351 * keyboard.c (pending_signals): Now bool, not int.
4353 Port timers to OpenBSD, plus check for timer failures.
4354 OpenBSD problem reported by Han Boetes.
4355 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4357 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4358 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4359 like OpenBSD, which has timer_settime but does not declare it.
4360 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4361 whether to use itimerspec-related primitives. All uses of
4362 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4364 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4366 * profiler.c (handle_profiler_signal): Fix a malloc race
4367 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4369 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4371 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4373 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4375 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4376 consistent with the change in return value of 'safe_strsignal'.
4378 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4380 Prefer plain 'static' to 'static inline' (Bug#12541).
4381 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4382 (bidi_set_sor_type, bidi_push_embedding_level)
4383 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4384 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4385 (bidi_cache_search, bidi_cache_ensure_space)
4386 (bidi_cache_iterator_state, bidi_cache_find)
4387 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4388 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4389 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4390 Now 'static', not 'static inline'.
4392 Count overruns when profiling; change units to ns.
4393 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4394 Give extra weight to samples after overruns, to attempt to count
4395 the time more accurately.
4396 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4397 the underlying primitives nominally do ns.
4398 (Fprofiler_cpu_start): Document the change. Mention that
4399 the sampling intervals are only approximate.
4401 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4403 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4405 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4406 case for the special 0 coding-system.
4408 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4409 (Fmake_overlay): Remove redundant tests.
4410 (fix_start_end_in_overlays): Remove redundant recentering.
4412 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4414 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4415 Update dependencies.
4417 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4419 Fix a malloc race condition involving strsignal.
4420 A signal can arrive in the middle of a malloc, and Emacs's signal
4421 handler can invoke strsignal, which can invoke malloc, which is
4422 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4423 Fix it by altering the signal handler so that it does not invoke
4425 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4426 * process.c (status_message): Use const pointer, in case strsignal
4427 is #defined to safe_strsignal.
4428 * sysdep.c (sys_siglist, init_signals): Always define and
4429 initialize a substitute sys_siglist if the system does not define
4430 one, even if HAVE_STRSIGNAL.
4431 (safe_strsignal): Rename from strsignal. Always define,
4432 using sys_siglist. Return a const pointer.
4433 * syssignal.h (safe_strsignal): New decl.
4434 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4436 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4438 * w32proc.c (timer_loop): Fix code that waits for timer
4439 expiration, to avoid high CPU usage.
4441 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4443 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4444 (sweep_weak_table): Remove redundant prototypes.
4446 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4448 * emacs.c: Move the inclusion of TERM_HEADER after including
4449 windows.h on WINDOWSNT. This avoids compilation problems with
4452 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4454 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4455 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4456 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4457 as the previous version used 'void *'.
4459 * ralloc.c (ROUNDUP): Fix last change.
4460 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4463 * w32proc.c <disable_itimers>: New static flag.
4464 (init_timers): Initialize it to zero, after creating the critical
4465 sections used by the timer threads.
4466 (term_timers): Set to 1 before deleting the critical sections.
4467 (getitimer, setitimer): If disable_itimers is non-zero, return an
4468 error indication without doing anything. Reported by Fabrice
4469 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4470 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4472 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4475 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4476 term_ntproc after all the other bookkeeping, to get timers working
4477 as long as possible.
4479 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4481 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4482 Suggested by Juri Linkov in
4483 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4485 Prefer plain 'static' to 'static inline' (Bug#12541).
4486 With static functions, modern compilers inline pretty well by
4487 themselves; advice from programmers often hurts as much as it helps.
4488 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4489 this change shrinks the text size of the Emacs executable by 1.1%
4490 without affecting CPU significantly in my benchmark.
4491 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4492 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4566 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
4567 Now 'static', not 'static inline'.
4570 (bidi_copy_it): Do the whole copy with a single memcpy.
4571 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4573 Revert the FOLLOW-SYMLINKS change for file-attributes.
4574 Doing it right would require several changes to Tramp, and there's
4575 not enough time to get that tested before the freeze today.
4576 * dired.c (directory_files_internal, Ffile_attributes):
4579 * frame.c (x_report_frame_params): Port better to wider ints.
4580 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4581 or that pointers can be printed in 15 decimal digits.
4582 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
4584 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>
4586 Support x64 build on MS-Windows.
4587 * w32term.h (SCROLL_BAR_PACK, SCROLL_BAR_UNPACK): Define for x64.

4592 * w32term.c (w32_draw_underwave): Don't use GCC extensions for
4593 defining an XRectangle structure.
4595 * w32proc.c (RVA_TO_PTR, w32_executable_type): Fix pointer
4596 arithmetics for compatibility with x64.
4598 * w32menu.c (add_menu_item): Use UINT_PTR instead of UINT, for
4599 compatibility with x64.
4601 * w32heap.h: Adjust prototypes and declarations.
4603 * w32heap.c (RVA_TO_PTR, allocate_heap, sbrk, init_heap)
4604 (round_heap): Use DWORD_PTR, ptrdiff_t and size_t instead of

4792 Prefer timer_settime if available, and prefer
4793 thread cputime clocks, then process cputime clocks, then
4794 monotonic clocks, to the old realtime clock. Use make_timeval
4795 to round more-correctly when falling back to setitimer.
4796 (Fprofiler_cpu_start): Use it.
4797 (Fprofiler_cpu_stop): Prefer timer_settime if available.

5067 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5069 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5070 fatal_error_backtrace.
5072 * w32proc.c (sys_kill): Undo last change: don't do anything when
5073 invoked to deliver SIGABRT to our own process. This is now
5074 handled by emacs_raise.
5076 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5078 * w32term.c (w32_read_socket): Remove leftover reference to
5079 interrupt_input_pending.
5081 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5083 Do not use SA_NODEFER.
5084 Problem reported by Dani Moncayo in
5085 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5087 * sysdep.c (emacs_abort): Do not reset signal handler.
5088 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5089 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5090 wanted even on POSIXish hosts, and it doesn't work on Windows.
5092 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5094 * xterm.c (x_term_init): Call fixup_locale before and after calling
5095 gtk_init (Bug#12392).
5097 2012-09-23 Chong Yidong <cyd@gnu.org>
5099 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5100 Vdynamic_library_alist.
5102 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5103 (Fgnutls_available_p): Caller changed.
5105 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5106 (Flibxml_parse_xml_region): Likewise.
5108 * dispextern.h (struct image_type): Remove arg from init function.
5110 * image.c (Finit_image_library, lookup_image_type)
5111 (define_image_type): Remove now-unneeded second arg.
5112 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5113 (init_tiff_functions, init_gif_functions, init_svg_functions):
5114 Arglist and w32_delayed_load calling convention changed.
5115 (gs_type): Remove init_gs_functions; there is no such function.
5116 (valid_image_p, make_image): Fix caller to lookup_image_type.
5118 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5120 Simplify and avoid signal-handling races (Bug#12471).
5122 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5123 Avoid recursive loop if there's a fatal error in the function itself.
5124 * atimer.c (pending_atimers):
5125 * blockinput.h: Don't include "atimer.h"; no longer needed.
5126 (interrupt_input_pending): Remove. All uses removed.
5127 pending_signals now counts both atimers and ordinary interrupts.
5128 This is less racy than having three separate pending-signal flags.
5129 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5131 Rename from their upper-case counterparts BLOCK_INPUT,
5132 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5133 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5134 This makes it easier to access volatile variables more accurately.
5135 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5136 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5137 that's more reliable if the code is buggy and sets
5138 interrupt_input_blocked to a negative value. All uses changed.
5139 * atimer.c (deliver_alarm_signal):
5140 Remove. No need to deliver this to the parent; any thread can
5141 handle this signal now. All uses replaced by underlying handler.
5142 * atimer.c (turn_on_atimers):
5143 * dispnew.c (handle_window_change_signal):
5144 * emacs.c (handle_danger_signal):
5145 * keyboard.c (kbd_buffer_get_event):
5146 Don't reestablish signal handler; not needed with sigaction.
5147 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5149 Rework to avoid unnecessary accesses to volatile variables.
5150 (UNBLOCK_INPUT_TO): Now a function.
5151 (totally_unblock_input, unblock_input): New decls.
5152 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5153 (init_data): Remove. Necessary stuff now done in init_signal.
5154 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5155 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5156 (fatal_error_code): Remove; no longer needed.
5157 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5158 it doesn't always backtrace. All uses changed. No need to reset
5159 signal to default, since sigaction and/or die does that for us now.
5160 Use emacs_raise (FOO), not kill (getpid (), FOO).
5161 (main): Check more-accurately whether we're dumping.
5162 Move fatal-error setup to sysdep.c
5163 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5164 * gtkutil.c (xg_get_file_name, xg_get_font):
5165 Remove no-longer-needed signal-mask manipulation.
5166 * keyboard.c, process.c (POLL_FOR_INPUT):
5167 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5168 * keyboard.c (read_avail_input): Remove.
5169 All uses replaced by gobble_input.
5170 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5171 (kbd_buffer_store_event_hold, gobble_input):
5172 (record_asynch_buffer_change) [USABLE_SIGIO]:
5173 (store_user_signal_events):
5174 No need to mess with signal mask.
5175 (gobble_input): If blocking input and there are terminals, simply
5176 set pending_signals to 1 and return. All hooks changed to not
5177 worry about whether input is blocked.
5178 (process_pending_signals): Clear pending_signals before processing
5179 them, in case a signal comes in while we're processing.
5180 By convention callers now test pending_signals before calling us.
5181 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5182 New functions, to support changes to blockinput.h.
5183 (handle_input_available_signal): Now extern.
5184 (reinvoke_input_signal): Remove. All uses replaced by
5186 (quit_count): Now volatile, since a signal handler uses it.
5187 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5188 All callers changed. Block SIGINT only if not already blocked.
5189 Clear sigmask reliably, even if Fsignal returns, which it can.
5190 Omit unnecessary accesses to volatile var.
5191 (quit_throw_to_read_char): No need to restore sigmask.
5192 * keyboard.c (gobble_input, handle_user_signal):
5193 * process.c (wait_reading_process_output):
5194 Call signal-handling code rather than killing ourselves.
5195 * lisp.h: Include <float.h>, for...
5196 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5197 (pending_signals): Now volatile.
5198 (syms_of_data): Now const if IEEE floating point.
5199 (handle_input_available_signal) [USABLE_SIGIO]:
5200 (terminate_due_to_signal, record_child_status_change): New decls.
5201 * process.c (create_process): Avoid disaster if memory is exhausted
5202 while we're processing a vfork, by tightening the critical section
5204 (send_process_frame, process_sent_to, handle_pipe_signal)
5205 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5207 (send_process): No need for setjmp/longjmp any more, since the
5208 SIGPIPE stuff is now gone. Instead, report an error if errno
5210 (record_child_status_change): Now extern. PID and W are now args.
5211 Return void, not bool. All callers changed.
5212 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5213 Remove. All uses removed. This bug should be fixed now in a
5215 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5216 and record the child status change directly. This avoids the
5217 need to futz with the signal mask.
5218 (process_fatal_action): Move here from emacs.c.
5219 (emacs_sigaction_flags): New function, containing
5220 much of what used to be in emacs_sigaction_init.
5221 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5222 caught by emacs, to make races less likely.
5223 (deliver_process_signal): Rename from handle_on_main_thread.
5225 (BACKTRACE_LIMIT_MAX): Now at top level.
5226 (thread_backtrace_buffer, threadback_backtrace_pointers):
5228 (deliver_thread_signal, deliver_fatal_thread_signal):
5229 New functions, for more-accurate delivery of thread-specific signals.
5230 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5231 (deliver_arith_signal): Handle in this thread, not
5232 in the main thread, since it's triggered by this thread.
5233 (maybe_fatal_sig): New function.
5234 (init_signals): New arg DUMPING so that we can be more accurate
5235 about whether we're dumping. Caller changed.
5236 Treat thread-specific signals differently from process-general signals.
5237 Block all signals while handling fatal error; that's safer.
5238 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5240 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5241 Ignore SIGPIPE unless batch.
5242 (emacs_backtrace): Output backtrace for the appropriate thread,
5243 which is not necessarily the main thread.
5244 * syssignal.h: Include <stdbool.h>.
5245 (emacs_raise): New macro.
5246 * xterm.c (x_connection_signal): Remove; no longer needed
5247 now that we use sigaction.
5248 (x_connection_closed): No need to mess with sigmask now.
5249 (x_initialize): No need to reset SIGPIPE handler here, since
5250 init_signals does this for us now.
5252 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5254 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5255 background rect may be larger (Bug#12245).
5257 2012-09-23 Chong Yidong <cyd@gnu.org>
5259 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5261 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5263 * .gdbinit: Just stop at fatal_error_backtrace.
5264 See Stefan Monnier's request in
5265 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5266 Remove no-longer-used query of system type.
5268 2012-09-22 Chong Yidong <cyd@gnu.org>
5270 * search.c (Freplace_match): Doc fix (Bug#12325).
5272 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5274 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5275 (Fline_end_position): Doc fix.
5277 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5279 2012-09-22 Chong Yidong <cyd@gnu.org>
5281 * dispextern.h (struct image_type): Add new slot, storing a type
5282 initialization function.
5284 * image.c (define_image_type): Call the image initializer function
5285 if it is defined. Arguments and return value changed.
5286 (valid_image_p, make_image): Callers changed.
5287 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5288 (gif_type, imagemagick_type, svg_type, gs_type):
5289 Add initialization functions.
5290 (Finit_image_library): Call lookup_image_type.
5291 (CHECK_LIB_AVAILABLE): Macro deleted.
5292 (lookup_image_type): Call define_image_type here, rather than via
5293 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5294 (syms_of_image): Move define_image_type calls for xbm_type and
5295 pbm_type to lookup_image_type.
5297 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5299 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5300 'idle_timers' from here ...
5301 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5302 lists, to avoid infloops when the timer does something stupid,
5303 like reinvoke itself with the same or smaller time-out.
5306 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5308 * window.c (Fsplit_window_internal): Handle only Qt value of
5309 Vwindow_combination_limit separately.
5310 (Qtemp_buffer_resize): New symbol.
5311 (Vwindow_combination_limit): New default value.
5314 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5316 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5317 the new overlay string. (Bug#10159)
5319 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5321 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5322 or that fprintf is async-signal-safe. POSIX doesn't require
5325 2012-09-22 Chong Yidong <cyd@gnu.org>
5327 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5330 2012-09-22 Kenichi Handa <handa@gnu.org>
5332 * composite.c (composition_reseat_it): Handle the case that a
5333 grapheme cluster is not covered by a single font (Bug#12352).
5335 2012-09-21 Chong Yidong <cyd@gnu.org>
5337 * image.c (define_image_type): Avoid adding duplicate types to
5338 image_types (Bug#12463). Suggested by Jörg Walter.
5340 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5342 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5343 (print_load_command_name): Add case LC_DATA_IN_CODE.
5344 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5346 2012-09-21 Glenn Morris <rgm@gnu.org>
5348 * eval.c (Frun_hook_with_args_until_success)
5349 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5351 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5353 * fileio.c (Ffile_selinux_context): Only call freecon when
5354 lgetfilecon succeeded.
5355 (Fset_file_selinux_context): Likewise. (Bug#12444)
5357 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5359 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5360 reordering, locate the cursor by calling set_cursor_from_row; if
5361 that fails, clear the desired glyph matrix before returning a
5362 failure indication to the caller. Fixes leaving garbled display
5363 when fast scrolling with a down-key. (Bug#12403)
5364 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5365 scrolling through multibyte text.
5367 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5369 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5370 calling mark_vectorlike since that's the one that marks the window.
5371 (mark_discard_killed_buffers): Mark the final cdr.
5372 * window.h (struct window): Move prev/next_buffers to the
5373 non-standard fields.
5374 * window.c (make_window): Initialize prev/next_buffers manually.
5376 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5378 Omit unused arg EXPECTED from socket hooks.
5379 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5380 * nsterm.m (ns_term_init):
5381 * termhooks.h (struct terminal.read_socket_hook):
5382 * w32inevt.c (w32_console_read_socket):
5383 * w32term.c (w32_read_socket):
5384 * xterm.c (XTread_socket):
5385 Omit unused arg EXPECTED. All callers changed.
5386 (store_user_signal_events): Return void, not int, since callers no
5387 longer care about the return value. All uses changed.
5389 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5391 * w32gui.h (XParseGeometry): Do not declare.
5393 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5395 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5396 Ignore 'expected'. See Eli Zaretskii in
5397 <http://bugs.gnu.org/12471#8> (last line).
5399 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5400 (XParseGeometry): Now static. Substitute extremal values for
5401 values that are out of range.
5403 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5405 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5407 * nsfns.m (XParseGeometry): Remove.
5408 (Fx_create_frame): Call x_set_offset to correctly interpret
5409 top_pos in geometry.
5411 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5412 (Fx_parse_geometry): If there is a space in string, call
5413 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5415 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5417 * search.c (scan_buffer): Use character positions in calls to
5418 region_cache_forward and region_cache_backward, not byte
5419 positions. (Bug#12196)
5421 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5422 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5424 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5425 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5426 emacs_blocked_malloc, now deleted.
5428 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5430 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5431 The workaround was for improving performance on Solaris 2.4, but
5432 is getting in the way now. Emacs will still work if someone is
5433 still running Solaris 2.4 in a museum somewhere; Sun dropped
5434 support for Solaris 2.4 in 2003.
5435 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5436 * process.c (create_process) [HAVE_WORKING_VFORK]:
5437 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5438 since Emacs no longer uses vfork on that platform.
5440 2012-09-17 Glenn Morris <rgm@gnu.org>
5442 * emacs.c: Use COPYRIGHT.
5444 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5446 Remove configure's --without-sync-input option (Bug#12450).
5447 When auditing signal-handling in preparation for cleaning it up,
5448 I found that SYNC_INPUT has race conditions and would be a real
5449 pain to fix. Since it's an undocumented and deprecated
5450 configure-time option, now seems like a good time to remove it.
5451 Also see <http://bugs.gnu.org/11080#16>.
5452 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5453 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5454 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5455 (malloc_hysteresis):
5456 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5457 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5458 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5459 (dont_register_blocks, bytes_used_when_reconsidered)
5460 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5461 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5462 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5463 Remove. All uses removed.
5464 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5465 implementation, one that depends on whether the new macro
5466 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5468 * atimer.c (run_timers, handle_alarm_signal):
5469 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5470 (handle_async_input, process_pending_signals)
5471 (handle_input_available_signal, init_keyboard):
5472 * nsterm.m (ns_read_socket):
5473 * process.c (wait_reading_process_output):
5474 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):

5477 * xterm.c (XTread_socket):
5479 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5480 * eval.c (handling_signal): Remove. All uses removed.
5481 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5482 All uses replaced with the SYNC_INPUT version.
5483 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5485 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5488 * font.c (Ffont_shape_gstring): Remove unused local.
5490 2012-09-16 Glenn Morris <rgm@gnu.org>
5492 * Makefile.in (clean): No longer run nextstep's clean.
5494 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5496 (ns-app): Move here from ns.mk, and simplify.
5497 (clean): Simplify nextstep entry.
5498 * ns.mk: Remove file.
5500 2012-09-17 Kenichi Handa <handa@gnu.org>
5502 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5503 not covert the last few charactes.
5505 2012-09-16 Kenichi Handa <handa@gnu.org>
5507 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5508 here, but just check the validity of glyphs in the glyph-string.
5510 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5512 * window.c (Fwindow_parameter, Fset_window_parameter):
5513 Accept any window as argument (Bug#12452).
5515 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5517 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5518 to ns_term_init to avoid memory leak.
5520 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5521 explicit retain/release.
5522 (ns_term_init): Only allow one display. Initialize outerpool and
5525 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5527 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5528 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5529 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5530 the Microsoft problem in a different way, by altering ../nt/config.nt.
5532 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5547 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5548 by lisp.h. This completes removal of setjmp.h inclusion
5549 erroneously announced in the previous commit. (Bug#12446)
5551 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5554 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5555 not defined as a macro. The latter happens on MS-Windows.
5558 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5560 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5561 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5562 Some instances of '#include <setjmp.h>' removed, if the
5563 only reason for the instance was because "lisp.h" was included.
5564 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5565 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5566 and _longjmp with the new symbols. Emacs already uses _setjmp if
5567 available, so this change affects only POSIXish hosts that have
5568 sigsetjmp but not _setjmp, such as some versions of Solaris and
5569 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5570 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5571 (png_load_body) [HAVE_PNG]:
5572 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5573 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5574 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5575 since PNG requires jmp_buf. This is the only exception to the
5576 general rule that we now use sys_setjmp and sys_longjmp.
5577 This exception is OK since this code does not change the signal
5578 mask or longjmp out of a signal handler.
5580 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5582 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5583 Include "syssignal.h", for 'main_thread'.
5585 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5587 Avoid out-of-range marker position (Bug#12426).
5588 * insdel.c (replace_range, replace_range_2):
5589 Adjust markers before overlays, as suggested by comments.
5590 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5591 Remove redundant check before calling offset_intervals.
5593 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5595 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5596 current buffer (Bug#12387).
5598 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5600 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5602 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5604 Use a more backwards-compatible timer format (Bug#12430).
5605 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5606 vector element, not from the 4th, since PSECS is now at the end.
5607 (Fcurrent_idle_time): Doc fix.
5609 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5611 Function to mark objects and remove killed buffers at once.
5612 * alloc.c (discard_killed_buffers): Rename to ...
5613 (mark_discard_killed buffers) ... new name. Add marking
5614 of remaining objects. Fix comment. Adjust users.
5615 (mark_object): Do not touch frame buffer lists here.
5616 * frame.c (delete_frame): Reset frame buffer lists here.
5618 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5620 Better workaround for GNOME bug when --enable-gcc-warnings.
5621 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5622 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5623 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5625 Simplify SIGIO usage (Bug#12408).
5626 The code that dealt with SIGIO was crufty and confusing, e.g., it
5627 played tricks like "#undef SIGIO" but these tricks were not used
5628 consistently. Simplify mostly by not #undeffing standard symbols,
5629 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5630 or not as we please) rather than "defined SIGIO" (standard symbol
5631 that we probably shouldn't #undef).
5632 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5633 Modules that need it can include it.
5634 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5635 * dispextern.h (ignore_sigio): New decl.
5636 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5637 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5638 * emacs.c (shut_down_emacs):
5639 * keyboard.c (kbd_buffer_store_event_hold):
5640 Use ignore_sigio rather than invoking 'signal' directly.
5641 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5643 (FIONREAD, SIGIO): Do not #undef.
5644 (tty_read_avail_input): Use #error rather than a syntax error.
5645 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5646 for I_PIPE, used by SETUP_SLAVE_PTY.
5647 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5648 * sysdep.c (croak): Remove; no longer needed. This bit of
5649 temporary code, with Fred N. Fish's comment that it's temporary,
5650 has been in Emacs since at least 1992!
5651 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5652 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5653 * syssignal.h (croak): Remove decl.
5654 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5655 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5656 now that we're termios-only.
5657 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5658 * term.c (dissociate_if_controlling_tty): Use #error rather than
5661 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5662 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5663 to work around GNOME bug 683906.
5664 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5665 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5666 This works around GCC bug 54561.
5668 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5670 More fixes for 'volatile' and setjmp/longjmp.
5671 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5672 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5673 (png_load_body) [HAVE_PNG]:
5674 (jpeg_load_body) [HAVE_JPEG]:
5675 New function, with most of the old parent function's body.
5676 (png_load) [HAVE_PNG]:
5677 (jpeg_load) [HAVE_JPEG]:
5678 Invoke the new function, to avoid longjmp munging our locals.
5679 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5680 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5681 longjmp is passed 2, as the C standard doesn't guarantee this.
5682 Instead, store the failure code into mgr->failure_code.
5684 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5686 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5687 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5688 (syms_of_keyboard): Remove support for unread-command-char.
5690 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5692 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5693 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5694 violation. (Bug#12426)
5696 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5698 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5700 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5702 * eval.c: Add `inhibit-debugger'.
5703 (Qinhibit_debugger): New symbol.
5704 (call_debugger): Bind it instead of Qdebug_on_error.
5705 (maybe_call_debugger): Test Vinhibit_debugger.
5706 (syms_of_eval): Define inhibit-debugger.
5707 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5708 (syms_of_xdisp): Remove inhibit-debug-on-message.
5710 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5712 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5713 If a nonvolatile local variable is written before a _longjmp to
5714 the frame containing the variable, and is read after the _longjmp,
5715 the value read is indeterminate. Some local variables of type
5716 'struct handler' and 'struct catchtag' are used in this way, so
5717 mark each of their slots as volatile if the slot can be set before
5718 _longjmp and read afterwards.
5719 * lisp.h (struct handler): var and chosen_clause are now volatile.
5720 (struct catchtag): val, next, and pdlcount are now volatile.
5722 * bidi.c (bidi_push_it, bidi_pop_it):
5723 * fns.c (copy_hash_table):
5724 * image.c (define_image_type):
5725 * keyboard.c (kbd_buffer_store_event_hold):
5726 * process.c (Fprocess_send_eof):
5727 * xfaces.c (x_create_gc) [HAVE_NS]:
5728 * xgselect.c (xg_select):
5729 Prefer assignment to memcpy when either will do.
5731 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5732 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5733 time an item is removed. No need to mark this function 'inline';
5734 the compiler knows better than we do.
5736 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5738 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5739 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5740 to change_frame_size (Bug#12388).
5741 (windowDidResize:): Pass YES to updateFrameSize.
5743 * nsterm.h: Add delay parameter to updateFrameSize.
5745 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5747 Discard killed buffers from deleted window and frame objects.
5748 This reduces an amount of references to killed buffers and
5749 helps GC to reclaim them faster.
5750 * alloc.c (discard_killed_buffers): New function.
5751 (mark_object): Use it for deleted windows and frames.
5752 (mark_object): If symbol's value is set up for a killed buffer
5753 or deleted frame, restore its global binding.
5754 * data.c (swap_in_global_binding): Add GC notice.
5755 (swap_in_symval_forwarding): Use convenient set_blv_where.
5756 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5757 * window.h: ... to here.
5759 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5761 Convenient macro to check whether the buffer is live.
5762 * buffer.h (BUFFER_LIVE_P): New macro.
5763 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5764 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5766 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5768 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5769 composition cases (Bug#12364).
5771 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5772 overhang of succeeding glyphs overlapping box cursor.
5774 * w32term.c (x_draw_glyph_string): Likewise.
5776 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5778 Simplify, document, and port floating-point (Bug#12381).
5779 The porting part of this patch fixes bugs on non-IEEE platforms
5780 with frexp, ldexp, logb.
5781 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5783 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5784 support, by removing commented-out code and briefly listing the
5785 C89 functions excluded. The commented-out stuff was confusing
5786 maintenance, e.g., we thought we needed cbrt but it was commented out.
5787 (logb): Remove decl; no longer needed.
5788 (isfinite): New macro, if not already supplied.
5789 (isnan): Don't replace any existing macro.
5790 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5791 are present on all C89 platforms.
5792 (Ffrexp): Do not special-case zero, as frexp does the right thing
5794 (Flogb): Do not use logb, as it doesn't have the desired meaning
5795 on hosts that use non-base-2 floating point. Instead, stick with
5796 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5797 frexp, to avoid getting an unspecified result.
5799 * xdisp.c (Qinhibit_debug_on_message): Now static.
5801 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5803 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5804 NSBezierPath (Bug#12131).
5806 2012-09-10 Chong Yidong <cyd@gnu.org>
5808 * fns.c (Fdelq, Fdelete): Doc fix.
5810 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5812 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5813 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5815 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5817 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5818 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5821 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5823 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5824 left fringe if the window has a left margin. This avoids leaving
5825 traces of the cursor because its leftmost pixel is not drawn over.
5827 * dispnew.c (update_window_line): When the left margin area of a
5828 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5829 that screen line. (Bug#12277)
5831 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5833 Assume C89 or later for math functions (Bug#12381).
5834 This simplifies the code, and makes it a bit smaller and faster,
5835 and (most important) makes it easier to clean up signal handling
5836 since we can stop worring about floating-point exceptions in
5837 library code. That was a problem before C89, but the problem
5838 went away many years ago on all practical Emacs targets.
5839 * data.c, image.c, lread.c, print.c:
5840 Don't include <math.h>; no longer needed.
5841 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5842 might be autoconfigured, as that never happens.
5844 * doprnt.c (DBL_MAX_10_EXP):
5845 * print.c (DBL_DIG):
5846 Remove. C89 or later always defines these.
5847 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5848 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5849 (arith_error, domain_error, domain_error2):
5850 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5851 no longer needed -- we simply return what C returns. All uses removed.
5852 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5854 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5855 Remove. All uses expanded, as these macros are no longer used
5856 more than once and are now more trouble than they're worth.
5857 (Ftan): Use tan, not sin / cos.
5858 (Flogb): Assume C89 frexp.
5859 (fmod_float): Assume C89 fmod.
5860 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5861 (init_floatfns): Remove. All uses removed.
5863 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5865 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5866 compositeToPoint for OSX < 10.6 (Bug#12390).
5868 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5870 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5871 This produces more-accurate results.
5873 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5875 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5876 changes (Bug#12088).
5878 2012-09-08 Chong Yidong <cyd@gnu.org>
5880 * syntax.c (Fstring_to_syntax): Doc fix.
5882 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5884 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5885 in the internal border.
5886 (x_set_window_size): Remove static variables and their usage.
5887 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5888 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5889 Remove fringe/internal border adjustment (Bug#11052).
5890 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5891 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5892 (ns_fix_rect_ibw): Remove.
5893 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5894 (ns_dumpglyphs_box_or_relief): Ditto.
5895 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5897 (ns_dumpglyphs_image): Ditto.
5898 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5900 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5901 their usage. Add fringe_extended_p and its use as in other terms.
5902 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5903 scroll bar was removed.
5904 (updateFrameSize): New function.
5905 (windowDidResize): Move code to updateFrameSize and call it.
5907 * nsterm.h (EmacsView): Add updateFrameSize.
5909 2012-09-07 Chong Yidong <cyd@gnu.org>
5911 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5913 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5915 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5917 More signal-handler cleanup (Bug#12327).
5918 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5919 Problem introduced when merging patches. Noted by Eli Zaretskii in
5920 <http://bugs.gnu.org/12327#67>.
5921 * floatfns.c: Comment fix.
5922 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5923 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5924 and anyway the declaration is harmless even if SIGDANGER is not defined.
5925 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5926 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5927 source files not surprisingly expected syssignal.h to define, or
5928 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5929 Include <sys/ioctl.h>, for FIONREAD.
5930 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5931 This eliminates a problem whereby other files mysteriously had
5932 to include "syssignal.h" before including "systty.h" if they
5933 wanted to use "#ifdef SIGIO".
5935 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5937 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5939 * w32.c (sigemptyset): Empty the set.
5940 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5942 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5944 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5946 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5947 (mark_object): Likewise for frame objects.
5949 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5951 * syssignal.h (handle_on_main_thread): Always declare,
5952 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5953 This ports to platforms without HAVE_PTHREAD.

5957 Signal-handler cleanup (Bug#12327).
5958 Emacs's signal handlers were written in the old 4.2BSD style with
5959 sigblock and sigmask and so forth, and this led to some
5960 inefficiencies and confusion. Rewrite these to use
5961 pthread_sigmask etc. without copying signal sets around. Also,
5962 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5963 'signal', and instead use functions that do not attempt to take
5964 over the system name space. This patch causes Emacs's text
5965 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5966 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5967 Do not include <signal.h> or "syssignal.h", as these
5968 modules do not use signals.
5969 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5970 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5971 Do not include <signal.h>, as "syssignal.h" does that for us now.
5972 * atimer.c (sigmask_atimers): New function.
5973 (block_atimers, unblock_atimers): New functions,
5974 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5976 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5977 no longer needed here.
5978 * emacs.c (main): Inspect existing signal handler with sigaction,
5979 so that there's no need to block and unblock SIGHUP.
5980 * sysdep.c (struct save_signal): New member 'action', replacing
5981 old member 'handler'.
5982 (save_signal_handlers, restore_signal_handlers):
5983 Use sigaction instead of 'signal' to save and restore.
5984 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5985 New function. All users of 'signal' modified to use set_sighandler
5986 if they're writeonly, and to use sys_signal if they're read+write.
5987 (emacs_sigaction_init, forwarded_signal): New functions.
5988 (sys_signal): Remove. All uses replaced by calls to sigaction
5989 and emacs_sigaction_init, or by direct calls to 'signal'.
5990 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5991 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5992 all uses replaced by pthread_sigmask etc. calls.
5993 * syssignal.h: Include <signal.h>.
5994 (emacs_sigaction_init, forwarded_signal): New decls.
5995 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5996 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5997 (sigmask, sys_sigmask): Remove; no longer needed.
5998 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5999 (sigblock, sigunblock, sigfree):
6000 (sigsetmask) [!defined sigsetmask]:
6001 Remove. All uses replaced by pthread_sigmask.
6002 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6003 no longer need to be replaced, and its typical old uses
6004 are now done via emacs_sigaction_init and sigaction.
6005 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6006 (sys_sigdel): Remove; unused.
6007 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6009 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6011 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6012 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6014 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6016 Explicitly mark buffer_defaults and buffer_local_symbols.
6017 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6018 mark_local_symbols here.
6019 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6020 since special buffers aren't marked here any more.
6021 (allocate_buffer): Chain new buffer with all_buffers here...
6022 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6024 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6025 (syms_of_buffer): Remove staticpro of the above.
6026 (init_buffer_once): Set names for buffer_defaults and
6027 buffer_local_symbols.
6029 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6031 Use bool for booleans in font-related modules.
6032 * font.c (font_intern_prop, font_style_to_value)
6033 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6034 (generate_otf_features, font_check_otf_features, font_check_otf)
6035 (font_match_p, font_list_entities, font_at):
6036 * fontset.c (fontset_id_valid_p, reorder_font_vector
6037 (fontset_find_font, Fset_fontset_font)
6038 (face_suitable_for_char_p) [0]:
6039 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6040 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6041 (m17n_flt_initialized, ftfont_shape_by_flt):
6042 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6043 * nsfont.m (nsfont_draw):
6044 * w32font.c (w32font_draw):
6045 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6046 Use bool for booleans.
6047 * font.h: Adjust to above API changes.
6048 (struct font, struct font_driver, struct font_driver_list):
6049 Use bool for booleans.
6050 (struct font): Remove useless member encoding_type.
6052 * fontset.c, xftfont.c: Omit unnecessary static decls.
6054 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6056 * alloc.c (mark_object): Revert window marking code
6057 since it's unsafe for the Fset_window_configuration.
6059 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6061 Fix race conditions with signal handlers and errno (Bug#12327).
6062 Be more systematic about preserving errno whenever a signal
6063 handler returns, even if it's not in the main thread. Do this by
6064 renaming signal handlers to distinguish between signal delivery
6065 and signal handling. All uses changed.
6066 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6067 * data.c (deliver_arith_signal): Rename from arith_error.
6068 * dispnew.c (deliver_window_change_signal): Rename from
6069 window_change_signal.
6070 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6071 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6072 * keyboard.c (deliver_input_available_signal): Rename from
6073 input_available_signal.
6074 (deliver_user_signal): Rename from handle_user_signal.
6075 (deliver_interrupt_signal): Rename from interrupt_signal.
6076 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6077 (deliver_child_signal): Rename from sigchld_handler.
6078 * atimer.c (handle_alarm_signal):
6079 * data.c (handle_arith_signal):
6080 * dispnew.c (handle_window_change_signal):
6081 * emacs.c (handle_fatal_signal, handle_danger_signal):
6082 * keyboard.c (handle_input_available_signal):
6083 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6084 * process.c (handle_pipe_signal, handle_child_signal):
6085 New functions, with the actual signal-handling code taken from the
6086 original respective signal handlers, sans the sporadic attempts to
6087 preserve errno, since that's now done by handle_on_main_thread.
6088 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6089 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6090 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6092 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6093 Move initialization of main_thread to sysdep.c's init_signals.
6094 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6095 our usage, and simplifies the mainline code.
6096 (record_child_status_change): New static function, as a helper
6097 for handle_child_signal, and with most of the old child handler's
6099 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6100 (handle_child_signal): Use the above.
6101 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6102 Moved here from emacs.c.
6103 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6104 code moved here from emacs.c's main function.
6105 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6106 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6107 This lets callers save and restore errno properly.
6109 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6111 Remove redundant or unused things here and there.
6112 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6113 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6114 * editfns.c (Fcompare_buffer_substrings): Likewise.
6115 * frame.h (struct terminal, struct font_driver_list):
6116 Remove redundant declarations.
6117 * window.h (Qleft, Qright): Likewise.
6119 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6121 Do not mark objects from deleted buffers, windows and frames.
6122 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6123 (mark_object): Likewise for windows and frames.
6125 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6127 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6128 buffer_defaults and buffer_local_symbols as valid objects.
6129 Return special value to denote them.
6131 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6133 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6134 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6135 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6136 (file_name_absolute_p, Fsubstitute_in_file_name):
6137 (check_executable, check_writable, Ffile_accessible_directory_p)
6138 (Fset_file_selinux_context, Fdefault_file_modes)
6139 (Finsert_file_contents, choose_write_coding_system)
6140 (Fwrite_region, build_annotations, a_write, e_write)
6142 * filelock.c (boot_time_initialized, get_boot_time)
6143 (get_boot_time_1, lock_file_1, within_one_second):
6144 * floatfns.c (in_float):
6145 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6146 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6147 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6148 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6149 * window.c (compare_window_configurations):
6150 Use bool for booleans.
6151 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6152 (Fdefault_file_modes): Now mode_t, not int, for modes.
6153 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6154 (internal_delete_file): Now returns void, not a (boolean) int,
6155 since nobody was looking at the return value.
6156 * lisp.h, window.h: Adjust to above API changes.
6158 * xdisp.c (set_message): Simplify and reindent last change.
6160 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6162 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6164 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6166 * eval.c (call_debugger): Make the function non-static so that we
6167 can call it from set_message.
6169 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6170 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6172 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6174 Give more-useful info on a fatal error (Bug#12328).
6175 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6176 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6177 of doing the work ourselves.
6178 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6179 do most of the work.
6180 (fatal_error_backtrace): New function, taken from the guts
6181 of the old fatal_error_signal, but with a new option to output
6183 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6184 info about the signal than just its number.
6185 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6186 * sysdep.c: Include <execinfo.h>
6187 (emacs_backtrace): New function, taken partly from the previous
6188 code of the 'die' function.
6189 (emacs_abort): Call fatal_error_backtrace rather than abort.
6191 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6193 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6194 eager (load-time) macro-expansion.
6195 * lisp.mk (lisp): Add macroexp.
6197 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6199 Simplify redefinition of 'abort' (Bug#12316).
6200 Do not try to redefine the 'abort' function. Instead, redo
6201 the code so that it calls 'emacs_abort' rather than 'abort'.
6202 This removes the need for the NO_ABORT configure-time macro
6203 and makes it easier to change the abort code to do a backtrace.
6204 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6205 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6206 Remove; sysdep.c's emacs_abort now takes its place.
6207 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6208 'abort' changed to use 'emacs_abort'.
6209 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6210 (abort) [!defined abort]: Rename to ...
6211 (emacs_abort): ... new name.
6212 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6213 the place of the old 'abort' in emacs.c.
6214 * w32.c, w32fns.c (abort): Do not #undef.
6215 * w32.c (emacs_abort): Rename from w32_abort.
6217 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6219 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6220 offsets[j].dv, since the y axis of the screen coordinates points
6221 down, while the y axis of the font definition coordinates points
6222 up. This fixes display of Arabic diacritics such as KASRA and
6223 KASRATAN. (Bug#11860)
6225 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6227 Be more systematic about _setjmp vs setjmp.
6228 * alloc.c (test_setjmp, mark_stack):
6229 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6230 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6231 (png_load, my_error_exit, jpeg_load):
6232 * process.c (send_process_trap, send_process):
6233 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6234 The underscored versions are up to 30x faster on some hosts.
6235 Formerly, the code used setjmp+longjmp sometimes and
6236 _setjmp+_longjmp at other times, with no particular reason to
6237 prefer setjmp+longjmp.
6239 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6241 Fix minor problem found by static checking.
6242 * buffer.c (Fdelete_all_overlays): Return nil.
6244 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6246 * buffer.c (Fdelete_all_overlays): New function.
6248 2012-09-03 Chong Yidong <cyd@gnu.org>
6250 * gtkutil.c: Add extern decl for Qxft.
6252 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6254 * emacs.c, eval.c: Use bool for boolean.
6255 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6256 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6257 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6258 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6259 (main, decode_env_path, Fdaemon_initialized):

6261 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6262 (maybe_call_debugger, Fbacktrace):
6263 * process.c (read_process_output, exec_sentinel):
6264 Use bool for booleans.
6265 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6266 All callers changed.
6267 * eval.c (interactive_p): Omit always-true boolean argument
6268 EXCLUDE_SUBRS_P. All callers changed.
6269 * dispextern.h, lisp.h: Reflect above API changes.
6270 * firstfile.c (dummy): Use the address of 'main', whose signature
6271 won't change, instead of the address of 'initialize', whose
6272 signature just changed from int to bool.
6273 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6274 * msdos.c (fatal_error_in_progress): ... from here.
6275 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6277 (redisplay_internal, unwind_redisplay): Simply clear
6278 REDISPLAYING_P when unwinding, instead of saving its previous,
6279 always-false value and then restoring it.
6281 Clean up some extern decls.
6282 Mostly, this hoists extern decls out of .c files and into .h files.
6283 That way, we're more likely to catch errors if the interfaces change.
6284 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6285 declare xg_mark_data.
6286 * dispextern.h (x_frame_parm_handlers):
6288 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6289 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6290 (Qultra_bold, Qoblique, Qitalic):
6291 Move extern decl here from .c file.
6292 * alloc.c (xg_mark_data) [USE_GTK]:
6294 * eval.c (Qlexical_binding):
6295 * fns.c (time) [!HAVE_UNISTD_H]:
6296 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6297 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

6299 * lread.c (Qinternal_interpreter_environment):
6300 * minibuf.c (Qbuffer):
6301 * process.c (QCfamily, QCfilter):
6302 * widget.c (free_frame_faces):
6303 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6304 * xfont.c (x_clear_errors):
6305 * xterm.c (x_frame_parm_handlers):
6306 Remove now-redundant extern decls.
6307 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6308 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6310 * xfaces.c: Remove unnecessary static decls.
6311 * xterm.c (updating_frame): Remove decl of nonexistent object.
6313 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6314 when building globals.h, as the objects that are not built on
6315 this host are not needed to compile C files on this host.
6317 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6319 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
6321 * frame.h: Add missing prototype for x_wm_set_size_hint.
6323 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6325 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

6327 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6328 (Fsubstitute_command_keys):

6331 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
6332 (format_time_string, general_insert_function)
6333 (make_buffer_string, make_buffer_string_both)
6334 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
6335 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

6347 * keyboard.c (decode_timer):
6348 Use bool for boolean.
6349 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6350 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
6352 2012-09-02 Chong Yidong <cyd@gnu.org>
6354 * keymap.c (push_key_description): Print M-TAB as C-M-i
6357 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6359 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

6367 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6369 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6370 more than one grapheme cluster passed to the shaper: compute the
6371 offset adjustment values separately for each cluster. (Bug#11860)
6373 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6374 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6375 about implicit conversions from integer to pointer.
6377 2012-09-01 Daniel Colascione <dancol@dancol.org>
6379 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

6397 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
6398 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
6399 all of which have been moved to common code.
6401 * xfaces.c: Include TERM_HEADER instead of listing all possible
6402 window-system headers.
6404 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

6429 window-system headers. Declare Vlibrary_cache when compiling for
6432 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6433 window system declarations.
6435 * frame.h: Move common functions here: set_frame_menubar,
6436 x_set_window_size, x_sync, x_get_focus_frame,
6437 x_set_mouse_position, x_set_mouse_pixel_position,
6438 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6465 * lisp.h (mark_ttys): Remove prototype.
6466 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6467 to mark_ttys because all possible values of 'top_frame' slot are
6468 the frames which are reachable from Vframe_list.
6469 * term.c (mark_ttys): Remove.
6470 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6472 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6474 Change struct frame bitfields from unsigned char to unsigned.
6475 * frame.h (struct frame): Change type of 'display_preempted',

6489 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
6490 does not become zero (Bug#12234).
6492 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6494 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6495 for GCC 4.7.1 x86-64.
6497 2012-08-30 Glenn Morris <rgm@gnu.org>
6499 * lread.c (init_lread): For out-of-tree builds, only add the
6500 source directory's site-lisp dir to the load-path if it exists,
6501 consistent with in-tree builds. (Bug#12302)
6503 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6505 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6519 Code formatting change.
6520 (timeout_handler:): Set timer_fired to YES.
6521 (runDialogAt:): Set timer_fired to NO.
6522 Handle click on close button as quit.
6524 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6525 Add window_closed and button_values. Add void as return value for
6526 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6527 Add process_dialog as new member.
6529 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6531 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6532 is not one of the heaps we manage. (Bug#12242)
6534 2012-08-28 Glenn Morris <rgm@gnu.org>
6536 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

6667 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6668 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6669 not a boolean 'int', since callers never look at the return value.
6670 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6671 * coding.h (decoding_buffer_size, encoding_buffer_size)
6672 (emacs_mule_string_char): Remove unused extern decls.
6673 (struct iso_2022_spec, struct coding_system):

6689 buffer doesn't appear in the selected window, go to its old
6692 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6694 Special MEM_TYPE_SPARE to denote reserved memory.
6695 * alloc.c (enum mem_type): New memory type.
6696 (refill_memory_reserve): Use new type for spare memory.
6697 This prevents live_cons_p and live_string_p from incorrect

6707 * window.c (Qwindow_valid_p, decode_valid_window):
6708 Now static, not extern.
6709 * data.c (Qinterval): Remove; unused.

6726 (map_sub_char_table):
6727 Use bool for boolean.
6728 * character.c (str_to_unibyte): Omit last boolean argument; it was
6729 always 0. All callers changed.
6730 * character.h, charset.h: Adjust to match previous changes.
6731 * character.h (char_printable_p): Remove decl of nonexistent function.
6732 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6733 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6734 are all boolean, so make them single-bit bitfields.
6736 * lisp.h (ASET): Remove attempt to detect side effects.
6737 It was meant to be temporary and it often doesn't work,
6738 because when IDX has side effects the behavior of IDX==IDX
6739 is undefined. See Stefan Monnier in
6740 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6742 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6744 * lisp.h (functionp): New function (extracted from Ffunctionp).
6745 (FUNCTIONP): Use it.
6746 * eval.c (Ffunctionp): Use it.
6748 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6750 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6751 as that's faster and simpler than static storage. Don't bother
6752 with the g_main_context_query overhead if g_main_context_pending
6753 says no events are pending.
6754 (gfds, gfds_size): Remove these static vars.
6755 (xgselect_initialize): Remove; no longer needed.
6756 All uses and decls removed.
6758 * emacs.c (fatal_error_signal_hook): Remove.
6759 All uses removed. This leftover from old code was always 0.
6761 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6762 * casefiddle.c (casify_object, casify_region):
6763 * casetab.c (set_case_table):

6774 On assertion failure, print backtrace if available.
6775 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6776 (die) [ENABLE_CHECKING]: Print a backtrace if available.

6785 * lisp.h (USE_SAFE_ALLOCA):
6786 Use bool for booleans, instead of int.
6787 * lisp.h, process.h: Adjust prototypes to match above changes.
6788 * callint.c (Fcall_interactively): Don't assume the mark's
6789 offset fits in 'int'.
6791 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6793 * buffer.c, buffer.h: Use bool for boolean.

6801 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6802 Use bool for booleans, instead of int.
6803 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6804 since the 1-or-0 return value is always ignored anyway.
6805 (mmap_initialized_p):
6806 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6807 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6809 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6811 * bidi.c: Use bool for boolean.
6812 This is a bit more readable, and makes the text segment of bidi.o
6813 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6814 Presumably it's faster too.
6815 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

6819 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6820 (bidi_explicit_dir_char, bidi_level_of_next_char)
6821 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6822 Use bool for booleans, instead of int.
6823 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6824 (bidi_unshelve_cache): Adjust decls to match code.
6826 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6828 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6831 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6833 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6834 * atimer.h: Include <stdbool.h>.
6836 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6838 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6839 compile time tests instead of run time tests on systems that do
6841 (FRAME_MAC_P): Remove leftover from deleted code.
6842 * frame.c (syms_of_frame): Remove leftover from deleted code.
6844 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6846 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6848 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6850 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6851 Otherwise, the compiler complains about (A?B:C) where B is void
6852 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6853 (fontset_add): Return void, for FONTSET_ADD.
6855 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6857 * alloc.c: Use bool for booleans.
6858 (gc_in_progress, abort_on_gc)
6859 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6860 (dont_register_blocks) [GC_MALLOC_CHECK]:
6861 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6862 (check_string_bytes, make_specified_string, memory_full)
6863 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6864 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6865 (mark_stack, valid_pointer_p, make_pure_string)
6866 (Fgarbage_collect, survives_gc_p, gc_sweep):
6867 Use bool for booleans, instead of int.
6868 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6869 Remove unused local.
6870 * alloc.c (PURE_POINTER_P):
6871 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6872 * editfns.c (Fformat):
6873 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6875 * fns.c (sweep_weak_table):
6876 * lisp.h (suppress_checking, push_message, survives_gc_p)
6877 (make_pure_string, gc_in_progress, abort_on_gc):
6878 * lread.c (readchar, read1):
6879 * print.c (Fprin1_to_string):
6880 * xdisp.c (push_message):
6881 Use bool for booleans affected directly or indirectly by
6884 Make recently-introduced setters macros.
6885 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6886 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6887 (set_fontset_default, set_fontset_fallback): Rename from their
6888 upper-case counterparts, and make them functions rather than macros.
6889 This is more consistent with the other recently-introduced setters.
6890 These don't need to be inline, since they're local.
6892 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6894 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6895 the loop (Bug#12247).
6897 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6899 * lisp.h (vcopy): Use memcpy rather than our own loop.
6900 This fixes a performance regression introduced by the recent
6901 addition of vcopy. This means 'vcopy' will need to be modified
6902 for a copying collector, but that's OK. Also, tighten the
6903 checking in the assertion.
6905 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6907 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6908 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6909 non-base glyph for the width of the base character, according to
6910 what x_draw_composite_glyph_string_foreground expects.
6911 Generate WADJUST value according to composition_gstring_width's
6912 expectations, to produce correct width of the composed character.
6913 Reverse the sign of the DU offset produced by ScriptPlace.
6915 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6917 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6919 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6921 Avoid direct writes to contents member of struct Lisp_Vector.
6922 * lisp.h (vcopy): New function to copy data into vector.
6923 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6924 * fns.c (Ffillarray): Use ASET.
6925 * keyboard.c (timer_check_2): Use AREF and ASET.
6926 (append_tool_bar_item, Frecent_keys): Use vcopy.
6927 * lread.c (read_vector): Use ASET.
6928 * msdos.c (Frecent_doskeys): Use vcopy.
6929 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6930 (Finternal_merge_in_global_face): Use ASET and vcopy.

6936 the position of its buffer's point.
6937 (Fset_window_point): For the selected window always go in its
6938 buffer to the specified position.
6940 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6942 Setter macros for fontsets.
6943 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6944 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6945 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6948 2012-08-20 Glenn Morris <rgm@gnu.org>
6950 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6951 Don't assume that `ln -f' works.
6953 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6955 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6956 and later about non-assignments with no effect. See discussion at
6957 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6960 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6962 Inline setter functions for Lisp_Objects slots of struct specbinding.
6963 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6966 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6968 * window.c (select_window): Always make selected window's buffer
6971 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6973 Use AREF and ASET for docstrings of category tables.
6974 * category.h (CATEGORY_DOCSTRING): Use AREF.
6975 (SET_CATEGORY_DOCSTRING): Use ASET.
6976 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6978 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6980 Inline setter functions for hash table members.
6981 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6982 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6983 (set_hash_key_and_value, set_hash_index, set_hash_next)
6984 (set_hash_hash): New functions.
6985 * charset.c, fns.c: Adjust users.
6987 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6989 Inline getter and setter functions for per-buffer values.
6990 * buffer.h (per_buffer_default, set_per_buffer_default)
6991 (per_buffer_value, set_per_buffer_value): New functions.
6992 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6993 * buffer.c, data.c: Adjust users.
6995 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6997 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6999 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7001 Rely on <config.h> + <unistd.h> to declare 'environ',
7002 as gnulib does this if the system doesn't.
7003 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7004 Remove declaration. MS-Windows declares it on stdlib.h which is
7005 included by conf_post.h.
7006 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7007 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7008 * vm-limit.c: Include <unistd.h>, for 'environ'.
7010 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7011 (start_of_data): Remove decl; mem-limits.h provides it.
7013 * xdisp.c (handle_invisible_prop): Make it a bit faster
7014 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7016 2012-08-19 Chong Yidong <cyd@gnu.org>
7018 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7021 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7023 * .gdbinit: Use call instead of set when calling a function in the
7026 * data.c (set_internal): Don't use set_blv_found.
7027 (Fkill_local_variable): Likewise.
7029 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7031 * nsfont.m (ns_ascii_average_width): Ensure the string
7032 ascii_printable is initialized with a null-terminated character
7033 array. Otherwise, it can contain undesired extra characters.
7035 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7037 port new setting code to Sun C 5.8 2005/10/13
7038 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7039 Return void, not Lisp_Object. Otherwise, the compiler
7040 complains about (A?B:C) where B is void and C is Lisp_Object
7041 when compiling CHAR_TABLE_SET, due to the recent change to
7042 the API of sub_char_table_set_contents.
7044 2012-08-18 Chong Yidong <cyd@gnu.org>
7046 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7047 for the string case (Bug#3874).
7049 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7051 * buffer.h (BSET): Remove (Bug#12215).

7202 The old version was confusing because it used the same name
7203 'parent' for two different things.
7205 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

7216 font spec, make the font's attributes take precedence over
7217 directly-specified attributes.
7218 (merge_face_ref): Recognize :font.
7220 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

7875 * w32.c (init_environment): Change the default values of many
7876 environment variables in dflt_envvars[] to NULL, to avoid pushing
7877 them into environment when they were not already defined.
7878 Remove the code that deletes site-lisp subdirectories from the default
7879 value of EMACSLOADPATH, as it is no longer needed.
7880 (check_windows_init_file): Now external, not static.
7881 Use Vload_path as is, without adding anything, as this function is now
7882 called when Vload_path is already set up.
7884 * w32.h (check_windows_init_file): Add prototype.
7886 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7918 (make_pure_float, make_pure_vector):
7919 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

7929 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7930 Remove unnecessary pointer casts.
7931 * alloc.c (record_xmalloc): New function.
7932 * lisp.h (record_xmalloc): New decl.
7933 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7934 more like a function. This is because the pointer cast is not
7935 needed. All uses changed.
7936 * print.c (print_string, print_error_message): Avoid length recalc.
7938 Improve fix for macroexp crash with debugging (Bug#12118).
7939 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7940 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7941 not supposed to be invoked from the garbage collector.
7942 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7943 (gc_aset): New function, which is like ASET but can be
7944 used in the garbage collector.

7960 headers (most versions of MinGW w32api don't).
7961 (get_security_info, create_symbolic_link)
7962 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7964 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7965 in the argument file name.

7968 (sys_rename): Diagnose renaming of a symlink when the user doesn't
7969 have the required privileges.
7970 (get_file_security_desc_by_name): Rename from
7971 get_file_security_desc.
7972 (stat_worker): New function, with most of the guts of 'stat', and
7973 with addition of handling of symlinks and support for 'lstat'.
7974 If possible, get file's attributes and security information by
7975 handle, not by name. Produce S_IFLNK bit for symlinks, when
7976 called from 'lstat'.
7977 (stat, lstat): New functions, call 'stat_worker'.
7978 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7979 symlinks when the underlying filesystem supports them.
7981 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7983 Fix macroexp crash on Windows with debugging (Bug#12118).
7984 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7985 checking subscripts; problem introduced with the recent
7986 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7987 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7988 since it's used in non-static inline functions now.
7990 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7991 Don't assume buffer size fits in 'int'. Remove unused local.

8011 * composite.c (COMPOSITE_INLINE):
8012 * dispnew.c (DISPEXTERN_INLINE):
8013 * sysdep.c (SYSTIME_INLINE):
8014 Define to EXTERN_INLINE, so that the corresponding functions
8015 are compiled into code.
8016 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8017 (INLINE_HEADER_END): New macros.
8018 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8038 hard-coding the path separator.
8040 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8042 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8043 This how ASET and AREF are supposed to work, and makes
8044 it easier to think about future improvements. See
8045 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8046 * charset.h (set_charset_attr): New function.

8427 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8428 (w32_kbd_patch_key, key_event): Use the codepage returned by
8429 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

8536 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from

8538 the fix for 12036 would have avoided some of the problems noted in
8539 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8540 would have been more obvious.
8541 * emacs.c: Do not include <verify.h>; no longer needed.

8550 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8551 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8552 not be usable in #if. This simplifies things.
8554 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8556 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8561 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8562 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8563 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8564 Adjust to changes in lisp.h and emacs.c, by using

8567 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8568 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8569 instead of gdb_valbits.

9477 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9478 * nsterm.m (ns_term_init):
9479 Avoid the need for strncpy, by using build_string or
9480 make_unibyte_string directly. Use dtoastr, not snprintf.
9481 * process.c (Fmake_network_process): Diagnose service names that
9482 are too long, rather than silently truncating them or creating
9483 non-null-terminated names.
9484 (Fnetwork_interface_info): Likewise, for interface names.
9485 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9486 Prefer sprintf to strncat.
9487 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

9513 Optimize pure C strings initialization.
9514 * lisp.h (make_pure_string): Fix prototype.
9515 (build_pure_c_string): New function, defined as static inline. This
9516 provides a better opportunity to optimize away calls to strlen when
9517 the function is called with compile-time constant argument.
9518 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9519 argument, adjust users accordingly. Use build_pure_c_string where
9521 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9522 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9523 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9525 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9527 Avoid calls to strlen in miscellaneous functions.
9528 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9529 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9530 * lread.c (openp): Likewise.
9532 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9534 Avoid calls to strlen in path processing functions.
9535 * fileio.c (file_name_as_directory): Add comment. Change to add
9536 srclen argument and return the length of result. Adjust users
9538 (directory_file_name): Fix comment. Change to add srclen argument,
9539 swap 1st and 2nd arguments to obey the common convention.
9540 Adjust users accordingly.
9541 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9543 2012-07-10 Glenn Morris <rgm@gnu.org>
9545 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9550 * s/gnu.h (DATA_START): Move definitions to configure.
9552 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9553 We include usg5-4-common.h, which defines them both.
9555 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9556 O_RDONLY already includes it).
9558 Stop ns builds setting the EMACSLOADPATH environment variable.
9559 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9560 Now it does not set EMACSLOADPATH, just returns the load-path string.
9561 * nsterm.h: Update accordingly.
9562 * lread.c [HAVE_NS]: Include nsterm.h.
9563 (init_lread) [HAVE_NS]: Use ns_load_path.

9566 2012-07-09 Glenn Morris <rgm@gnu.org>
9568 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9569 since the included bsd-common.h does so.
9571 Stop ns builds setting the EMACSPATH environment variable.
9572 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9573 (ns_init_paths): Do not set EMACSPATH.
9574 * nsterm.h (ns_exec_path): Add it.
9575 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9578 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9580 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9582 * process.c (wait_reading_process_output): 'waitchannels' was unset
9583 when read_kbd || !NILP (wait_for_cell); fix this.
9585 Add GCC-style 'const' attribute to functions that can use it.
9586 * character.h (char_resolve_modifier_mask):
9587 * keyboard.h (make_ctrl_char):
9588 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9597 Add decls with ATTRIBUTE_CONST.
9599 Minor improvements to make_formatted_string.
9600 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9601 where int is good enough, as vsprintf returns an int.
9602 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9604 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9606 Use make_formatted_string to avoid double length calculation.
9607 * lisp.h (make_formatted_string): New prototype.
9608 * alloc.c (make_formatted_string): New function.
9609 * buffer.c (Fgenerate_new_buffer_name): Use it.

9614 (x_report_frame_params): Likewise.
9615 * image.c (gs_load): Likewise.
9616 * minibuf.c (get_minibuffer): Likewise.

9631 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9633 Move marker debugging code under MARKER_DEBUG.
9634 * marker.c (MARKER_DEBUG): Move marker debugging code under
9635 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9636 for bootstrap with --enable-checking (~3x slowdown reported
9637 by Juanma Barranquero <lekktu@gmail.com>).
9638 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9640 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9642 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9643 See <http://bugs.gnu.org/11825#29>.
9645 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9647 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9648 has no font, use the frame's font. (Bug#11813)
9649 (display_line): Add commentary about displaying truncation glyphs
9651 (produce_special_glyphs): Move here from term.c.
9653 * term.c (produce_special_glyphs): Move to xdisp.c.
9655 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9658 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9660 * xdisp.c (display_line): Avoid warning about implicit declaration
9663 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9665 * lisp.h: Remove empty conditional.
9667 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9669 * lread.c (load_path_check): Now static.
9671 Fix some minor --with-ns problems found by static checking.
9672 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9673 (x_set_font) [!HAVE_X_WINDOWS]:
9674 * image.c (xpm_load_image) [HAVE_NS]:
9675 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9676 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9677 Remove unused local.
9678 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9679 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9680 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9681 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9682 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9683 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9684 Fix pointer signedness problem.
9685 * xfaces.c (FRAME_X_FONT_TABLE):
9686 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9688 2012-07-07 Glenn Morris <rgm@gnu.org>
9690 * lread.c (load_path_check): New function, split from init_lread.
9691 (init_lread): Reorganize. Motivation:
9692 If EMACSLOADPATH is set, check/warn about that rather than the
9693 defaults, which we are not going to use. Hence we can remove
9694 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9695 Don't warn if site-lisp directories are missing.
9696 If not installed, start from a blank load-path, since
9697 PATH_LOADSEARCH refers to the eventual installation directories.
9699 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9701 Support truncation and continuation glyphs on GUI frames, when
9702 fringes are disabled. (Bug#11832)
9703 * xdisp.c (init_iterator): Get dimensions of truncation and
9704 continuation glyphs even if on GUI frames.
9705 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9706 or both, are absent.
9707 (start_display, move_it_in_display_line_to): Handle the case of a
9708 GUI frame without a fringe to display continuation or truncation
9710 (insert_left_trunc_glyphs): Support GUI frames: make sure
9711 truncation glyphs overwrite enough glyphs from the current line to
9712 have sufficient space in pixels.
9713 (display_line): Support truncation and continuation glyphs on GUI
9714 frames. If some spare pixels are left on the line after inserting
9715 the truncation glyphs, fill that space with a stretch glyph of a
9716 suitably computed width.
9718 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9719 produce_glyphs, to support GUI sessions.
9721 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9723 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9725 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9727 Do not require float-time's arg to fit in time_t (Bug#11825).
9728 This works better on hosts where time_t is unsigned, and where
9729 float-time is applied to the (negative) difference between two times.
9730 * editfns.c (decode_time_components): Last arg is now double *,
9731 not int *, and means to store all the result as a double, without
9732 worrying about whether the seconds part fits in time_t.
9733 All callers changed.
9734 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9735 All callers changed.
9736 (Ffloat_time): Do not fail merely because the specified time falls
9737 outside of time_t range.
9739 2012-07-07 Glenn Morris <rgm@gnu.org>
9741 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9756 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9757 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9758 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

9761 * xfont.c (compare_font_names): Redo to omit the need for casts.
9763 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9765 * xfns.c (Fx_change_window_property): Doc fix.
9766 * w32fns.c (Fx_change_window_property): Doc fix.
9768 * w32fns.c (Fx_window_property): Accept the same arguments as the
9769 X Windows version. Doc fix.
9770 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9772 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9773 Eli Zaretskii <eliz@gnu.org>
9775 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9776 Windows-specific code from nt/config.nt moved here.
9777 Obsolete settings removed.
9779 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9781 * process.c: Avoid unnecessary calls to gettime.
9782 (wait_reading_process_output): Don't get the time of day
9783 when gobbling data immediately and not waiting, as there's no need
9784 for it in that case. This removes a FIXME.
9786 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9788 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9789 is defined (Bug#11768).
9791 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9793 Fix marker debugging code.
9794 * marker.c (byte_char_debug_check): Do not perform the check
9795 if buffer is not multibyte.
9796 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9797 Call byte_char_debug_check with correct arguments.
9799 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9801 Compile marker debugging code only if ENABLE_CHECKING is defined.
9802 * marker.c (byte_char_debug_check, count_markers):
9803 Use only if ENABLE_CHECKING is defined.
9804 (byte_debug_flag): Remove.
9805 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9806 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9808 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9810 Avoid code repetition in marker-related functions.
9811 * marker.c (attach_marker): New function.
9812 (Fset_marker, set_marker_restricted, set_marker_both)
9813 (set_marker_restricted_both): Use it.
9814 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9815 Consistently rename charno to charpos.
9816 (marker_position): Add eassert.
9817 (marker_byte_position): Convert to eassert.

9836 * window.c (save_window_save): Likewise.
9838 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9840 Do not use Fdelete_overlay in delete_all_overlays
9841 to avoid redundant calls to unchain_overlay.
9842 * buffer.c (drop_overlay): New function.
9843 (delete_all_overlays, Fdelete_overlay): Use it.
9844 * minibuf.c (get_minibuffer): Fix comment.
9846 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9848 Port to OpenBSD 5.1 amd64.
9849 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9850 This is needed for OpenBSD, and should be harmless on all BSD systems.
9851 Also, include <sys/sysctl.h>, as it should be available on all
9852 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9853 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9854 use p_pid member, not kp_proc.pid.
9856 2012-07-06 Glenn Morris <rgm@gnu.org>
9858 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9860 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9862 More xmalloc and related cleanup.
9863 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9864 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

9869 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9870 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9871 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9873 Omit needless casts involving void * pointers and allocation.
9874 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9875 as the former is more robust if P's type is changed.
9876 Prefer xzalloc to xmalloc + memset 0.
9877 Simplify malloc-or-realloc to realloc.
9878 Don't worry about xmalloc returning a null pointer.
9879 Prefer xstrdup to xmalloc + strcpy.
9880 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9882 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9883 alloca of a constant.
9885 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9887 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9888 hscroll is larger than the line width. Fixes long and futile
9889 looping inside extend_face_to_end_of_line (on a TTY) producing
9890 glyphs that are not needed and thrown away.
9892 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9894 * marker.c (set_marker_restricted_both): Simplify by using
9897 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9899 * editfns.c (region_limit): Simplify by using clip_to_bounds.

9908 followed by gtk_box_set_homogeneous (Bug#11768).
9909 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9910 (update_theme_scrollbar_width, xg_create_scroll_bar):
9911 Use gtk_scrollbar_new (Bug#11768).
9912 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9913 (is_box_type): New function (Bug#11768).
9914 (xg_tool_item_stale_p): Call is_box_type.
9915 (xg_initialize): Get settings by calling gtk_settings_get_for_screen

9988 * fileio.c (time_error_value): Check the right error number.
9989 Problem reported by Troels Nielsen in
9990 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9992 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9994 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9995 This should be fixed in a better way; see Eli Zaretskii in
9996 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9997 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9999 * fileio.c (time_error_value): Rename from special_mtime.
10000 The old name's problems were noted by Eli Zaretskii in
10001 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10003 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10004 This variable's comment says Emacs needs at least one GDB-visible
10005 symbol of type enum pvec_type, to work around GDB problems.
10006 The symbol's value doesn't matter.
10008 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10009 that causes compilation to fail on pre-C99 compilers.
10011 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10013 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10016 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10018 * buffer.c (init_buffer_once): Fix initialization of
10019 headers for buffer_defaults and buffer_local_symbols.
10020 Reported by Juanma Barranquero <lekktu@gmail.com>.
10022 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10024 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10025 * lisp.h (enum pvec_type): Use fewer bits.
10026 (PSEUDOVECTOR_SIZE_BITS): New constant.
10027 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10028 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10029 change in pvec_type.
10030 (PSEUDOVECTOR_TYPEP): New macro.
10031 (TYPED_PSEUDOVECTORP): Use it.
10032 * fns.c (internal_equal): Adapt code to extract pvectype.
10033 * emacs.c (gdb_pvec_type): Update type.
10034 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10035 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10036 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10037 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10038 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10039 abusing vector->header.next.nbytes.
10040 (live_vector_p): Use PVEC_TYPE.
10041 (mark_object): Adapt code to extract pvectype. Use switch.
10043 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10045 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10046 Tighten new eassert a bit.
10048 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10050 Fix compilation with --enable-gcc-warnings and -O1
10051 optimization level.
10052 * doprnt.c (doprnt): Change type of tem to int, initialize
10053 to avoid compiler warning. Add eassert.
10054 * search.c (simple_search): Initialize match_byte to avoid
10055 compiler warning. Add eassert.
10057 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10059 Avoid weird behavior with large horizontal scrolls.
10060 Without this change, for example, large hscroll values would
10061 mess up Emacs's display on Fedora 15 x86, presumably due to
10062 overflows in int calculations in the display code.
10063 Also, if buffers had long lines, Emacs would freeze.
10064 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10065 (set_window_hscroll): New function, containing the old guts of
10066 Fset_window_hscroll. Return the clipped value.
10067 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10068 This avoids the need to check against PTRDIFF_MAX.
10070 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10072 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10074 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10076 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10078 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10079 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10080 since GCC 4.4.6 issues a bogus warning for them.
10082 Fix bugs in file timestamp newness comparisons.
10083 * fileio.c (Ffile_newer_than_file_p):
10084 * lread.c (Fload): Use full timestamp resolution of files,
10085 not just the 1-second resolution, so that files that are only
10086 slightly newer still count as newer.
10087 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10088 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10090 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10092 * fileio.c: Improve handling of file time marker. (Bug#11852)
10093 (special_mtime): New function.
10094 (Finsert_file_contents, Fverify_visited_file_modtime):
10095 Use it to set special mtime values consistently.
10097 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10099 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10100 marker for non-existing file. (Bug#11852)
10102 2012-07-03 Glenn Morris <rgm@gnu.org>
10104 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10105 and did not make it into globals.h).
10107 2012-07-03 Tom Tromey <tromey@redhat.com>
10109 * window.c (Fset_window_margins, Fset_window_fringes)
10110 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10111 * textprop.c (Fprevious_property_change): No longer static.

10136 * font.h: Remove EXFUNs.
10137 * dosfns.c (system_process_attributes): Remove EXFUN.
10138 * keymap.h: Remove EXFUNs.
10139 * lisp.h: Remove EXFUNs.
10140 * w32term.h: Remove EXFUNs.
10141 * window.h: Remove EXFUNs.
10142 * xsettings.h: Remove EXFUN.
10143 * xterm.h: Remove EXFUN.
10145 2012-07-03 Glenn Morris <rgm@gnu.org>
10147 * lisp.h (Frandom): Make it visible to C.
10148 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10149 buffer for invisible buffers. (Bug#1229)
10151 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10153 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10154 values which aren't power of 2.
10155 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10156 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10159 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10161 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10163 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10165 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10167 * alloc.c (allocate_vector_block): Remove redundant
10168 calls to mallopt if DOUG_LEA_MALLOC is defined.
10169 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10170 avoid calls to mallopt if zero_vector is returned.
10172 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10174 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10175 is enabled, avoid dereferencing NULL current_sblock if
10178 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10180 Cleanup basic buffer management.
10181 * buffer.h (struct buffer): Change layout to use generic vector
10182 marking code. Fix some comments. Change type of 'clip_changed'
10183 to bitfield. Remove unused #ifndef old.
10184 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10185 (GET_OVERLAYS_AT): Fix indentation.
10186 (for_each_per_buffer_object_at): New macro.
10187 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

10191 struct buffer. Fix comment.
10192 (mark_overlay): New function.

10195 (mark_object): Use it. Adjust marking of misc objects
10196 and related comments.
10198 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10200 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10201 wrapper that is not needed because the wrapped code is a no-op (zero
10202 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10203 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10205 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10207 * alloc.c (mark_buffer): Simplify. Remove prototype.
10208 (mark_object): Add comment. Reorganize marking of vector-like
10209 objects. Use CHECK_LIVE for all vector-like objects except buffers
10210 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10211 Avoid redundant calls to mark_vectorlike for bool vectors.
10213 2012-06-30 Glenn Morris <rgm@gnu.org>
10215 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10217 * epaths.in (PATH_SITELOADSEARCH): New.
10218 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10219 This is rather than relying on --enable-locallisppath elements
10220 having "site-lisp" in their names. (Bug#10208#25, 11658)
10222 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10224 * w32proc.c (sys_select): Accept and ignore one more argument.
10226 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10228 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10229 (pselect) [!MS_DOS]: Redirect to sys_select.
10231 * sysdep.c: Don't include dos.h and dosfns.h.
10233 * process.c (sys_select):
10234 * msdos.c (sys_select): Accept one more argument and ignore it.
10236 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10237 adapt data types and code to that.
10240 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10241 which clashes with the gnulib function of the same name.
10243 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10245 * font.c (font_style_to_value, font_style_symbolic)
10246 (font_prop_validate_style): Add type checks for values in
10249 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10251 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10254 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10256 * xdisp.c (try_window_id): Undo last change.
10258 * w32.c (getwd): Adjust commentary about startup_dir.
10259 (init_environment): Always call sys_access, even in non-MSVC
10260 builds. Don't chdir to the directory of the Emacs executable.
10261 This undoes code from 1997 which was justified by the need to
10262 "avoid conflicts when removing and renaming directories". But its
10263 downside was that every relative file name was being interpreted
10264 relative to the directory of the Emacs executable, which can never
10265 be TRT. In particular, it broke sys_access when called with
10266 relative file names.
10267 (sys_access): Map GetLastError to errno.
10269 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10271 * window.h (struct window): Change type of 'fringes_outside_margins'
10272 to bitfield. Fix comment. Adjust users accordingly.
10273 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10275 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10278 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10280 * gnutls.c (emacs_gnutls_handshake):
10281 Add QUIT to make the loop interruptible.
10283 2012-06-29 Glenn Morris <rgm@gnu.org>
10285 * charset.c (init_charset): Make lack of etc/charsets fatal.
10287 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10289 * editfns.c (region_limit): Fix type mismatch.
10291 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10293 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10294 undefined. Convert from xassert to eassert.
10295 * nsmenu.m: Convert from xassert to eassert.
10296 * nsterm.m: Likewise.
10298 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10300 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10302 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10304 Avoid integer overflow on scroll-left and scroll-right.
10305 * window.c (HSCROLL_MAX): New macro.
10306 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10307 overflow when requested scroll falls outside ptrdiff_t range.
10309 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10311 * window.h (struct window): Change type of 'hscroll',
10312 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10313 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10314 Adjust users accordingly.
10315 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10316 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10317 from EMACS_INT to ptrdiff_t.
10318 (make_window): Omit redundant initialization.
10320 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

10337 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10338 adjust comments accordingly.

10394 * alloc.c (make_uninit_multibyte_string): Initialize intervals
10395 as in make_pure_string and make_pure_c_string.
10397 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10399 * alloc.c (allocate_string): Fix last change.
10401 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10403 * alloc.c (allocate_string): Remove two redundant calls
10404 to memset, add explicit initialization where appropriate.

10451 * alloc.c: Remove build_string.
10452 * lisp.h: Define build_string as static inline. This provides
10453 a better opportunity to optimize away calls to strlen when the
10454 function is called with compile-time constant argument.
10455 * image.c (imagemagick_error): Convert to build_string.
10456 * w32proc.c (sys_spawnve): Likewise.
10457 * xterm.c (x_term_init): Likewise.
10459 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10461 Use sprintf return value instead of invoking strlen on result.
10462 In the old days this wasn't portable, since some sprintf
10463 implementations returned char *. But they died out years ago and
10464 Emacs already assumes sprintf returns int.
10465 Similarly for float_to_string.
10466 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10467 * ccl.c (ccl_driver):
10468 * character.c (string_escape_byte8):

10471 * print.c (print_object):
10472 * xdisp.c (message_dolog):
10473 * xfns.c (syms_of_xfns):
10474 Use sprintf or float_to_string result to avoid need to call strlen.
10475 * data.c (Fnumber_to_string):
10476 Use make_unibyte_string, since the string must be ASCII.
10477 * lisp.h, print.c (float_to_string): Now returns int length.
10478 * term.c (produce_glyphless_glyph):
10479 Use sprintf result rather than recomputing it.
10481 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10482 * Makefile.in (ALL_CFLAGS):
10483 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10484 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10486 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10488 * dispextern.h (xstrcasecmp): Define to library function
10489 strcasecmp if available.
10490 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10492 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10494 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10505 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10507 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10508 sprintf already null-terminates its output.
10510 * xfns.c (x_window): Remove redundant cast.
10512 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10514 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10515 `const char *' to `char *' to avoid compiler warning.
10517 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10519 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10520 instead of truncating it to 63 (admittedly a generous limit).
10522 * process.c: Fix spelling and caps in comments.
10524 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10526 * emacs.c (setpgrp): Remove definition, unused.

10536 (SYSTIME_H): Add nt/inc/sys/time.h.
10538 * systime.h [WINDOWSNT]: Include sys/time.h.
10540 * s/ms-w32.h (struct timespec): Definition moved from
10541 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10543 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10573 Remove unnecessary forward decls.
10575 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10577 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10578 * lisp.h (WAIT_READING_MAX): New macro.
10579 * dispnew.c (Fsleep_for, sit_for):
10580 * keyboard.c (kbd_buffer_get_event):
10581 * process.c (Faccept_process_output):
10582 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10583 This improves on the previous patch, which introduced a bug
10584 when time_t is unsigned and as wide as intmax_t.
10585 See <http://bugs.gnu.org/9000#51>.
10587 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10589 * dispnew.c (sit_for, Fsleep_for):
10590 * keyboard.c (kbd_buffer_get_event):

10596 * makefile.w32-in: Update dependencies.
10598 * w32.c (ltime): Add return type and declare static.
10599 (w32_get_internal_run_time): Remove usused variable `time_100ns'.

10603 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10604 Privately reported by Herbert J. Skuhra.
10605 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10607 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10608 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10610 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10612 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10613 last argument of make_unibyte_string.
10615 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10616 language ID in the event parameters.
10618 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10619 event.code, not the obscure "character set ID".
10621 2012-06-23 Chong Yidong <cyd@gnu.org>
10623 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
10625 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10627 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

10637 in the logic of incrementing and decrementing the value of
10638 use_relocatable_buffers.

10642 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
10643 Privately reported by Herbert J. Skuhra.
10644 [__FreeBSD__]: Remove "*/" typo after "#include".

10646 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10647 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10648 Don't assume EMACS_TIME and struct timeval are the same type.
10650 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10652 Support higher-resolution time stamps (Bug#9000).
10653 The time stamps are only nanosecond-resolution at the C level,
10654 since that's the best that any real-world system supports now.
10655 But they are picosecond-resolution at the Lisp level, as that's
10656 easy, and leaves room for future OS improvements.
10658 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10661 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10662 Don't get current time unless it's needed.
10664 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10665 now provides it if it's absent.
10666 (start_atimer): Port to higher-res time stamps.
10667 Check for time stamp overflow. Don't get current time more
10668 often than is needed.
10670 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10671 Include systime.h, not time.h.
10672 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10674 * dired.c: Include stat-time.h.
10675 (Ffile-attributes): File times now have higher resolution.
10677 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10678 (struct image): Timestamp now has higher resolution.
10680 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10681 has at least microseconds now. All uses removed.
10682 (update_frame, update_single_window, update_window, update_frame_1)
10683 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10684 (duration_to_sec_usec): Remove; no longer needed.
10686 * editfns.c (time_overflow): Now extern.
10687 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10688 (float-time, Fformat_time_string, Fcurrent_time_string)
10689 (Fcurrent_time_zone): Accept and generate higher-resolution
10691 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10692 (decode_time_components, lisp_seconds_argument): New functions.
10693 (make_time): Now static.
10694 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10695 Report an error if the time is invalid, rather than having the caller
10698 * fileio.c: Include <stat-time.h>
10699 (Fcopy_file): Copy higher-resolution time stamps.
10700 Prefer to set the time stamp via a file descriptor if that works.
10701 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10702 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10703 (Fvisited_file_modtime, Fset_visited_file_modtime):
10704 Support higher-resolution time stamps.
10706 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10708 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10710 * image.c (prepare_image_for_display, clear_image_cache)
10711 (lookup_image): Port to higer-resolution time stamps.
10713 * keyboard.c (start_polling, bind_polling_period):
10714 Check for time stamp overflow.
10715 (read_char, kbd_buffer_get_event, timer_start_idle)
10716 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10717 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10718 Port to higher-resolution time stamps. Do not assume time_t is signed.
10719 (decode_timer): New function. Timers are now vectors of length 9,
10720 not 8, to accommodate the picosecond component.
10721 (timer_check_2): Use it.
10723 * nsterm.m (select_timeout, timeval_subtract): Remove.
10724 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10725 as they're a bit more accurate and handle overflow better.
10726 (ns_select): Change prototype to be compatible with pselect.
10727 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10728 * nsterm.h (ns_select): Adjust prototype.
10730 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10731 us-resolution time stamps.
10732 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10734 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10736 * lisp.h (time_overflow): New decl.
10737 (wait_reading_process_output): First arg is now intmax_t, not int,
10738 to accommodate larger waits.
10740 * process.h (struct Lisp_Process.read_output_delay):
10741 Now counts nanoseconds, not microseconds.
10742 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10744 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10745 (wait_reading_process_output):
10746 Port to ns-resolution time stamps.
10747 (Faccept_process_output, wait_reading_process_output):
10748 Check for time stamp overflow. Do not assume time_t is signed.
10749 (select_wrapper): Remove; we now use pselect.
10750 (Fprocess_attributes): Now generates ns-resolution time stamps.
10752 * sysdep.c: Include utimens.h. Don't include utime.h
10753 or worry about struct utimbuf; gnulib does that for us now.
10754 (gettimeofday): Remove; gnulib provides a substitute.
10755 (make_timeval): New function.
10756 (set_file_times): Now sets ns-resolution time stamps.
10757 New arg FD; all uses changed.
10758 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10759 (system_process_attributes):
10760 Now returns ns-resolution time stamp. All uses changed.
10761 Check for time stamp overflow.
10763 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10764 provides a substitute now.
10766 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10767 since it guarantees struct timespec.
10768 (EMACS_TIME): Now struct timespec, so that we can support
10769 ns-resolution time stamps.
10770 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10771 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10772 (EMACS_USECS): Remove.
10773 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10774 so multiply the arg by 1000 before storing it.
10775 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10777 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10778 Port to ns-resolution time stamps.
10779 (EMACS_TIME_NEG_P): Remove; replaced by....
10780 (EMACS_TIME_SIGN): New macro.
10781 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10782 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10783 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10784 (make_timeval, make_lisp_time, decode_time_components): New decls.
10785 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10786 that it mishandled time_t overflow. You can't compare by subtracting!
10787 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10788 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10790 * term.c: Include <sys/time.h>.
10791 (timeval_to_Time): New function, for proper overflow wraparound.
10792 (term_mouse_position, term_mouse_click): Use it.
10794 * undo.c (record_first_change): Support higher-resolution time stamps
10795 in the undo buffer.
10796 (Fprimitive_undo): Use them when restoring time stamps.
10798 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10799 (w32_get_internal_run_time):
10800 Port to higher-resolution Emacs time stamps.
10801 (ltime): Now accepts single 64-bit integer, as that's more convenient
10804 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10806 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10807 for compatibility with pselect. Support ns-resolution time stamps.
10809 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10811 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10812 Check for time stamp overflow, and support ns-resolution time stamps.
10814 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10815 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10816 (timeval_subtract): Remove; no longer needed.
10817 (XTflash, XTring_bell, x_wait_for_event):
10818 Port to ns-resolution time stamps. Don't assume time_t is signed.
10820 2012-06-22 Chong Yidong <cyd@gnu.org>
10822 * xdisp.c (x_consider_frame_title): Revert last change.
10824 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10826 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10827 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10828 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10829 staticidx goes up to 1597 out of 1600 = 0x640.)
10831 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10833 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10834 Otherwise, the umask might be mistakenly 0 while handling input signals.
10836 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10838 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11104 Use an inline function on all platforms when using the union type,

11289 (Fbuffer_local_value): Use it.
11290 (Vmode_line_format): Docstring tweaks.
11292 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11294 * sysdep.c (system_process_attributes): Improve comment.
11296 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
11298 * keyboard.c: Export real-this-command to Elisp.
11299 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11300 and DEFVAR it. Update all users.
11302 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11304 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11306 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11307 Convert pctcpu and pctmem to Lisp float properly.
11308 Let the compiler fold better, as 100.0/0x8000 is exact.
11310 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11312 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11315 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11317 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11319 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11321 For a 'struct window', replace some Lisp_Object fields to
11322 bitfields where appropriate, remove unused fields.
11323 * window.h (struct window): Remove unused 'last_mark_x' and
11324 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11325 change its type from Lisp_Object to bitfield.
11326 Change type of 'force_start', 'optional_new_start',
11327 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11328 fields from Lisp_Object to bitfield. Adjust users accordingly.
11330 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11332 Pacify gcc -Wdouble-precision when using Xaw.
11333 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11334 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11335 Use 'float' consistently, rather than 'float' in most places
11336 and 'double' in a couple of places.
11338 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11340 * xdisp.c (handle_stop): Detect whether we have overlay strings
11341 loaded by testing it->current.overlay_string_index to be
11342 non-negative, instead of checking whether n_overlay_strings is
11343 positive. (Bug#11587)
11345 2012-05-31 Chong Yidong <cyd@gnu.org>
11347 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11349 * doc.c (Fsubstitute_command_keys): Doc fix.
11351 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11353 * search.c (search_buffer): Remove calls to
11354 r_alloc_inhibit_buffer_relocation, as it is now called by
11355 maybe_unify_char, which was the cause of relocation of buffer text
11358 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11360 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11361 for the duration of call to load_charset, to avoid problems with
11362 callers of maybe_unify_char that access buffer text through C
11365 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11366 decrement the inhibition flag, instead of just setting or
11369 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11371 Remove obsolete '#define static' cruft.
11372 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11373 This #undef was "temporary" in 2000; it is no longer needed
11374 now that '#define static' has gone away.
11375 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11376 (gray_bitmap_bits): Remove; no longer needed.
11377 All uses replaced with definiens.
11378 * xterm.c: Include "bitmaps/gray.xbm".
11380 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11382 Clean up __executable_start, monstartup when --enable-profiling.
11383 The following changes affect the code only when profiling.
11384 * dispnew.c (__executable_start): Rename from safe_bcopy.
11385 Define only on platforms that need it.
11386 * emacs.c: Include <sys/gmon.h> when profiling.
11387 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11388 (__executable_start): Remove decl, since lisp.h does it now.
11389 (safe_bcopy): Remove decl; no longer has that name.
11390 (main): Coalesce #if into single bit of code, for simplicity.
11391 Cast pointers to uintptr_t, since standard libraries want integers
11393 * lisp.h (__executable_start): New decl.
11395 2012-05-31 Glenn Morris <rgm@gnu.org>
11397 * image.c (Fimagemagick_types): Doc fix.
11399 2012-05-30 Jim Meyering <meyering@redhat.com>
11401 * callproc.c (Fcall_process_region): Include directory component
11402 in mkstemp error message (Bug#11586).
11404 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11406 * alloc.c, lisp.h (make_pure_vector): Now static.
11408 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
11410 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
11411 Move to byte-run.el.

11413 * data.c (Fdefalias): Purify definition, except for keymaps.
11414 (Qdefun): Move from eval.c.
11415 * lisp.h (Qdefun): Remove.
11416 * lread.c (read1): Tiny simplification.
11418 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11420 Do not create empty overlays with the evaporate property (Bug#9642).
11421 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11422 Bug#9642, but explicitly check that the buffer the overlay would
11423 be moved to is live and rearrange lines to make sure that errors
11424 will not put the overlay in an inconsistent state.
11425 (Fdelete_overlay): Cosmetics.
11427 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11429 * w32term.c (my_bring_window_to_top): New function.
11430 (x_raise_frame): Use handle returned by DeferWindowPos, which
11431 could be different from the original one.
11432 Call my_bring_window_to_top instead of my_set_foreground_window.
11435 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11436 by calling BringWindowToTop.
11438 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

11441 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11443 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11444 This avoids undefined behavior that might cause the eassert
11445 to not catch an out-of-range value.
11447 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11449 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11450 Update dependencies.
11452 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11454 * bidi.c (bidi_mirror_char): Fix last change.
11456 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11458 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11459 when referring to sectname field in printf format.
11461 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11463 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11464 Only r_alloc_inhibit_buffer_relocation needed to be added;
11465 the others were already declared.
11467 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11468 before checking whether it's out of range. Put the check inside
11470 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11472 2012-05-27 Ken Brown <kbrown@cornell.edu>
11474 * callproc.c (Fcall_process): Restore a line that was accidentally
11475 commented out in the 2011-02-13 change (bug#11547).
11477 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11479 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11480 defined on ralloc.c.
11482 * buffer.c [REL_ALLOC]: Remove prototypes of
11483 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11484 they are now on lisp.h.
11486 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11488 * search.c (search_buffer): Use it to inhibit relocation of buffer
11489 text while re_search_2 is doing its job, because re_search_2 is
11490 passed C pointers to buffer text. (Bug#11519)
11492 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11493 Update value to 24.
11495 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11496 state after an additional call to move_it_in_display_line_to, keep
11497 the values of it->max_ascent and it->max_descent found for the
11499 (pos_visible_p): Revert the comparison against bottom_y to what it
11500 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11503 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11505 Fix coding-related core dumps with gcc -ftrapv.
11506 The code was computing A - B, where A and B are pointers, and B is
11507 random garbage. This can lead to core dumps on platforms that
11508 have special pointer registers, and it also leads to core dumps on
11509 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11510 A - B only when B is initialized properly.
11511 * coding.c (coding_set_source, coding_set_destination): Return void.
11512 (coding_change_source, coding_change_destinations): New functions,
11513 with the old behaviors of coding_set_source and coding_set_destination.
11514 All callers that need an offset changed to use these new functions.
11516 2012-05-26 Glenn Morris <rgm@gnu.org>
11518 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11520 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11522 Extend mouse support on W32 text-mode console.
11523 * xdisp.c (draw_row_with_mouse_face):
11524 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11526 * w32console.c: Include window.h.
11527 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11529 (initialize_w32_display): Initialize mouse-highlight data.
11531 * w32inevt.c: Include termchar.h and window.h.
11532 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11533 moves, call note_mouse_highlight. If help_echo changed, call
11534 gen_help_event to produce help-echo message in the echo area.
11535 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11538 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11540 * lread.c (read1): Simplify slightly to avoid an overflow warning
11541 with GCC 4.7.0 on x86-64.
11543 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11545 * bidi.c (bidi_mirror_char): Revert last change: an int is
11546 definitely wide enough here.
11548 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11550 Fix integer width and related bugs (Bug#9874).
11551 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11552 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11553 (string_bytes, check_sblock, allocate_string_data):
11554 (compact_small_strings, Fmake_bool_vector, make_string)
11555 (make_unibyte_string, make_multibyte_string)
11556 (make_string_from_bytes, make_specified_string)
11557 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11558 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11560 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11561 (allocate_pseudovector):
11562 Use int, not EMACS_INT, where int is wide enough.
11563 (inhibit_garbage_collection, Fgarbage_collect):
11564 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11565 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11566 int might not be wide enough.
11567 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11568 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11569 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11570 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11571 (bidi_level_of_next_char, bidi_move_to_visually_next):
11572 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11573 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11574 (Fkill_buffer, Fset_buffer_major_mode)
11575 (advance_to_char_boundary, Fbuffer_swap_text)
11576 (Fset_buffer_multibyte, overlays_at, overlays_in)
11577 (overlay_touches_p, struct sortvec, record_overlay_string)
11578 (overlay_strings, recenter_overlay_lists)
11579 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11580 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11581 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11582 (Foverlay_recenter, last_overlay_modification_hooks_used)
11583 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11584 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11585 (validate_region): Omit unnecessary test for b <= e,
11586 since that's guaranteed by the previous test.
11587 (adjust_overlays_for_delete): Avoid pos + length overflow.
11588 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11589 (report_overlay_modification):
11590 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11591 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11592 Omit pointer cast, which isn't needed anyway, and doesn't work
11593 after the EMACS_INT -> ptrdiff_t change.
11594 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11595 * buffer.h: Adjust decls to match defn changes elsewhere.
11596 (struct buffer_text, struct buffer):
11597 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11598 Use EMACS_INT, not int, where int might not be wide enough.
11599 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11600 not int, to avoid needless 32-bit limit on 64-bit hosts.
11601 (exec_byte_code): Use tighter memory-full test, one that checks
11602 for alloca overflow. Don't compute the address of the object just
11603 before an array, as that's not portable. Use EMACS_INT, not
11604 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11605 * callint.c (Fcall_interactively):
11606 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11607 * callproc.c (call_process_kill, Fcall_process):
11608 Don't assume pid_t fits into an Emacs fixnum.
11609 (call_process_cleanup, Fcall_process, child_setup):
11610 Don't assume pid_t fits into int.
11611 (call_process_cleanup, Fcall_process, delete_temp_file)
11612 (Fcall_process_region):
11613 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11614 (Fcall_process): Simplify handling of volatile integers.
11615 Use int, not EMACS_INT, where int will do.
11616 * casefiddle.c (casify_object, casify_region, operate_on_word)
11617 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11618 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11619 (casify_object): Avoid integer overflow when overallocating buffer.
11620 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11621 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11622 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11623 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11624 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11625 integers are now checked earlier. All uses replaced with XINT.
11627 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11628 For CCL_MapSingle, check that content and value are in int range.
11629 (ccl_driver, Fregister_code_conversion_map):
11630 Check that Vcode_version_map_vector is a vector.
11631 (resolve_symbol_ccl_program): Check that vector header is in range.
11632 Always copy the vector, so that we can check its contents reliably
11633 now rather than having to recheck each instruction as it's being
11634 executed. Check that vector words fit in 'int'.
11635 (ccl_get_compiled_code, Fregister_ccl_program)
11636 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11637 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11638 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11639 contents are in range.
11640 (Fccl_execute_on_string): Check that status is in range.
11641 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11642 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11643 Accept and return EMACS_INT, not int, because callers can pass values
11644 out of 'int' range.
11645 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11646 (multibyte_chars_in_text, parse_str_as_multibyte)
11647 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11648 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11649 (string_escape_byte8, Fget_byte):
11650 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11651 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11652 avoid mishandling large integers.
11653 * character.h: Adjust decls to match defn changes elsewhere.
11654 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11655 (Ffind_charset_region):
11656 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11657 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11658 (load_charset_map_from_vector, Fdefine_charset_internal):
11659 Don't assume fixnum fits in int.
11660 (load_charset_map_from_vector, Fmap_charset_chars):
11661 Remove now-unnecessary CHECK_NATNUMs.
11662 (Fdefine_charset_internal): Check ranges here, more carefully.
11663 Don't rely on undefined behavior with signed left shift overflow.
11664 Don't assume unsigned int fits into fixnum, or that fixnum fits
11665 into unsigned int. Don't require max_code to be a valid fixnum;
11666 that's not true for gb10830 4-byte on a 32-bit host. Allow
11667 invalid_code to be a cons, for the same reason. Require code_offset
11668 to be a character. Avoid int overflow if max_char is close
11670 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11671 this is intended anyway and avoids some undefined behavior.
11672 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11673 INDEX_TO_CODE_POINT, as that's what it expects.
11674 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11675 * charset.h (DECODE_CHAR): Return int, not unsigned;
11676 this is what was intended anyway, and it avoids undefined behavior.
11677 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11678 integer-overflow issues.
11679 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11680 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11681 where the argument is EMACS_INT, and this behavior is not intended.
11682 * chartab.c (Fmake_char_table, Fset_char_table_range)
11683 (uniprop_get_decoder, uniprop_get_encoder):
11684 Don't assume fixnum fits in int.
11685 * cmds.c (move_point): New function, that does the gist of
11686 Fforward_char and Fbackward_char, but does so while checking
11687 for integer overflow more accurately.
11688 (Fforward_char, Fbackward_char): Use it.
11689 (Fforward_line, Fend_of_line, internal_self_insert)
11690 (internal_self_insert):
11691 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11692 Fix a FIXME, by checking for integer overflow when calculating
11693 target_clm and actual_clm.
11694 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
11695 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)
11696 (ASSURE_DESTINATION, coding_alloc_by_realloc)
11697 (coding_alloc_by_making_gap, alloc_destination)

12378 Move its few remaining bits of functionality to where they're needed.
12379 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12380 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12381 * m/template.h: Remove.
12382 * Makefile.in (M_FILE): Remove. All uses removed.
12383 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12384 * lisp.h (USE_LSB_TAG):
12385 * mem-limits.h (EXCEEDS_LISP_PTR):
12386 Use VAL_MAX, not VALBITS, in #if.
12387 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12388 (EMACS_UINT): Define unconditionally now.
12389 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12390 (BITS_PER_EMACS_INT): New constants, replacing
12391 what used to be in config.h, but not useful in #if.
12392 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12393 define them any more.
12394 (VAL_MAX): New macro.
12396 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12397 BITS_PER_EMACS_INT, in #if.
12398 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12399 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12400 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12401 * s/ms-w32.h (DATA_START):
12402 Move here from removed file m/intel386.h.
12403 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12404 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12406 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12408 Assume C89 or later.
12409 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12410 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12412 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12413 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12414 * textprop.c, tparam.c (NULL): Remove.
12415 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12416 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12417 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12418 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12419 * xterm.c (input_signal_count): Assume volatile works.
12421 2012-05-21 Ken Brown <kbrown@cornell.edu>
12423 * xgselect.c (xg_select): Fix first argument in call to 'select'
12426 2012-05-20 Ken Brown <kbrown@cornell.edu>
12428 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12429 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12431 2012-05-19 Ken Brown <kbrown@cornell.edu>
12433 * xfns.c (x_in_use): Remove `static' qualifier.
12434 * xterm.h (x_in_use): Declare.
12435 * xgselect.c: Include xterm.h.
12436 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12437 and `display_arg' (bug#9754).
12439 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12441 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12443 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12444 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12446 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12448 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12450 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12451 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12453 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12454 reference to image_cache->refcount.
12455 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12457 2012-05-17 Juri Linkov <juri@jurta.org>
12459 * search.c (Fword_search_regexp, Fword_search_backward)
12460 (Fword_search_forward, Fword_search_backward_lax)
12461 (Fword_search_forward_lax): Move functions to isearch.el
12462 (bug#10145, bug#11381).
12464 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12466 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12468 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12470 * lread.c (init_obarray): Declare Qt and Qnil as special.
12472 2012-05-14 Glenn Morris <rgm@gnu.org>
12474 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12475 Put "libexec" before "bin", for the sake of init_callproc_1.
12477 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12479 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12481 * unexaix.c: Port to more-recent AIX compilers.
12482 (report_error, report_error_1, make_hdr, copy_sym)
12483 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12484 Make arguments const char *, not char *, to avoid violations of C
12485 standard and to fix some AIX warnings reported by Gilles Pion.
12487 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12489 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12490 already have overlays loaded.
12491 (handle_single_display_spec): Before returning without displaying
12492 fringe bitmap, synchronize the bidi iterator with the main display
12493 iterator, by calling iterate_out_of_display_property.
12494 (iterate_out_of_display_property): Detect buffer iteration by
12495 testing that it->string is a Lisp string.
12496 (get_next_display_element): When the current object is exhausted,
12497 and there's something on it->stack, call set_iterator_to_next to
12498 proceed with what's on the stack, instead of returning zero.
12499 (set_iterator_to_next): If called at the end of a Lisp string,
12500 proceed to consider_string_end without incrementing string
12501 position. Don't increment display vector index past the end of
12502 the display vector. (Bug#11417)
12503 (pos_visible_p): Don't report a position visible when move_it_to
12504 stopped at the last line of window, which happens to be scanned
12505 backwards by the bidi iteration. (Bug#11464)
12507 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12509 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12510 and right-margin display specs even if the spec is invalid or we
12511 are on a TTY, and thus unable to display on the fringes.
12512 That's because the text with the property will not be displayed anyway,
12513 so we need to signal to the caller that this is a "replacing"
12514 display spec. This fixes display when the spec is invalid or we
12517 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12519 * unexaix.c (make_hdr): Fix typo in prototype.
12520 This bug broke the build on AIX. Problem reported by Gilles Pion.
12522 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12524 * keyboard.c (kbd_buffer_get_event): Read special events also in
12525 batch mode. (Bug#11415)
12527 2012-05-12 Glenn Morris <rgm@gnu.org>
12529 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12531 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12533 * lisp.mk (lisp): Add newcomment.elc.
12535 2012-05-12 Glenn Morris <rgm@gnu.org>
12537 * Makefile.in (MKDIR_P): New, set by configure.
12538 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12540 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12542 Remove unused function hourglass_started.
12543 * dispextern.h (hourglass_started):
12544 * w32fns.c (hourglass_started):
12545 * xdisp.c (hourglass_started): Remove.
12547 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12549 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12550 Update dependencies.
12552 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12554 * xgselect.c (xg_select): Put maxfds+1 into a var.
12555 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12557 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12559 2012-05-10 Dave Abrahams <dave@boostpro.com>
12561 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12562 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12564 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12566 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12567 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12568 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12569 Initialize xd_registered_buses.
12571 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12573 Untag more efficiently if USE_LSB_TAG.
12574 This is based on a proposal by YAMAMOTO Mitsuharu in
12575 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12576 For an admittedly artificial (nth 8000 longlist) benchmark on
12577 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12578 Emacs's overall text size by 1%.
12579 * lisp.h (XUNTAG): New macro.
12580 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12581 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12582 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12583 * eval.c (Fautoload):
12584 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12585 * frame.h (XFRAME): Use XUNTAG.
12587 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12588 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12589 Remove unportable assumptions about print widths of types like
12591 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12592 intptr_t when converting between pointer and integer, to avoid GCC
12593 warnings about wrong width.
12595 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12597 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12598 stack for each reader_thread, instead of defaulting to 8MB
12599 determined by the linker. This avoids failures in creating
12600 subprocesses on Windows 7, see the discussion in this thread:
12601 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12603 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12605 Fix up display of the *Minibuf-0* buffer in the mini window.
12606 * keyboard.c (read_char): Don't clear the echo area if there's no
12608 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12609 contents of *Minibuf-0*) if there's no message displayed in its stead.
12611 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12613 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12616 2012-05-06 Chong Yidong <cyd@gnu.org>
12618 * lisp.mk (lisp): Update.
12620 2012-05-05 Jim Meyering <meyering@redhat.com>
12622 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12624 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12626 * data.c (PUT_ERROR): New macro.
12627 (syms_of_data): Use it. Add new error type `user-error'.
12628 * undo.c (user_error): New function.
12629 (Fprimitive_undo): Use it.
12630 * print.c (print_error_message): Adjust print style for `user-error'.
12631 * keyboard.c (user_error): New function.
12632 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12634 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12636 Do not limit current-time-string to years 1000..9999.
12637 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12638 (Fcurrent_time_string): Support any year that is supported by the
12639 underlying localtime representation. Don't use asctime, as it
12640 has undefined behavior for years outside the range -999..9999.
12642 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12644 Fix race conditions involving setenv, gmtime, localtime, asctime.
12645 Without this fix, interrupts could mess up code that uses these
12646 nonreentrant functions, since setting TZ invalidates existing
12647 tm_zone or tzname values, and since most of these functions return
12648 pointers to static storage.
12649 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12650 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12651 Grow the critical sections to include not just invoking
12652 localtime/gmtime, but also accessing these functions' results
12653 including their tm_zone values if any, and any related TZ setting.
12654 (format_time_string): Last arg is now struct tm *, not struct tm **,
12655 so that the struct tm is saved in the critical section.
12656 All callers changed. Simplify allocation of initial buffer, partly
12657 motivated by the fact that memory allocation needs to be outside
12658 the critical section.
12660 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12662 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12663 with RESET_INTERVAL.
12665 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12666 Remove duplicated buffer name initialization.
12668 2012-05-02 Jim Meyering <jim@meyering.net>
12670 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12672 * xfns.c (x_window): Use xstrdup (Bug#11375).
12674 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12676 * xdisp.c (pos_visible_p): If already at a newline from the
12677 display string before the 'while' loop, don't walk back the glyphs
12678 from it3.glyph_row. Solves assertion violation when the display
12679 string begins with a newline (egg.el). (Bug#11367)
12681 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12683 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12686 2012-05-01 Glenn Morris <rgm@gnu.org>
12688 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12689 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12690 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12691 All were removed before 23.1.
12693 * dispnew.c: Remove HAVE_LIBNCURSES test;
12694 it is always true on relevant platforms.
12696 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12697 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12699 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12701 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12703 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12704 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12707 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12709 Do not avoid creating empty evaporating overlays (Bug#9642).
12710 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12711 That is, do not delete an evaporating overlay if it becomes
12712 empty after its bounds are adjusted to fit within its buffer.
12713 This fix caused other problems, and I'm reverting it until we get
12714 to the bottom of them.
12716 2012-04-27 Chong Yidong <cyd@gnu.org>
12718 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12720 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12722 * xdisp.c (pos_visible_p): If the window start position is beyond
12723 ZV, start the display from buffer beginning. Prevents assertion
12724 violation in init_iterator when the minibuffer window is scrolled
12725 via the scroll bar.
12727 * window.c (window_scroll_pixel_based): Likewise.
12729 2012-04-27 Chong Yidong <cyd@gnu.org>
12731 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12733 2012-04-27 Glenn Morris <rgm@gnu.org>
12735 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12736 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12738 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12740 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12741 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12743 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12745 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12746 display element, check also the underlying string or buffer
12747 character. (Bug#11341)
12749 * w32menu.c: Include w32heap.h.
12750 (add_menu_item): If the call to AppendMenuW (via
12751 unicode_append_menu) fails, disable Unicode menus only if we are
12752 running on Windows 9X/Me.
12754 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12756 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12757 (xgetint): Add missing shift for LSB tags.
12759 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12761 * keyboard.c (read_char): Don't wipe echo area for select window
12762 events: These might get delayed via `mouse-autoselect-window'
12765 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12767 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12768 manipulation of :loaded-from data.
12770 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12772 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12773 now a cons (bug#11311).
12775 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12777 Do not create empty overlays with the evaporate property (Bug#9642).
12778 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12779 if it becomes empty after its bounds are adjusted to fit within
12780 its buffer. Without this fix, in a nonempty buffer (let ((o
12781 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12782 yields an empty overlay that has the evaporate property, which is
12783 not supposed to happen.
12785 Fix minor GTK3 problems found by static checking.
12786 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12787 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12788 (struct _EmacsFixedClass, emacs_fixed_get_type):
12789 Move decls here from emacsgtkfixed.h, since they needn't be public.
12790 (emacs_fixed_get_type): Now static.
12791 (emacs_fixed_class_init): Omit unused local.
12792 (emacs_fixed_child_type): Remove; unused.
12793 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12794 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12795 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12796 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12797 (EMACS_FIXED_GET_CLASS): Remove; unused.
12798 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12800 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12801 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12803 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12805 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12806 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12807 (__malloc_size_t, __malloc_ptrdiff_t):
12808 Remove. All uses removed, replaced by the definiens if needed,
12809 since we can assume C89 or better now.
12810 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
12811 (protect_malloc_state, align, get_contiguous_space)

12898 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12900 * sysdep.c [__FreeBSD__]: Minor cleanups.
12901 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12902 Use Emacs indenting style more consistently. Avoid some casts.

12986 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12987 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12988 (NEED_MEM_INSERT): New macro.
12989 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12990 Remove one incorrect comment and fix another.

13009 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13011 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

13026 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13027 * s/netbsd.h, s/sol2-6.h:
13028 Remove definition of GC_MARK_STACK, since the default now works.
13029 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13030 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's

13057 2012-04-11 Daniel Colascione <dancol@dancol.org>
13059 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13060 against is gone. It's better to use vfork now so that when Cygwin
13061 gains a new, working vfork, we use it automatically (bug#10398).
13063 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13084 being loaded (bug#10424).
13086 2012-04-09 Glenn Morris <rgm@gnu.org>
13088 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

13107 attempts per process (connection).
13109 2012-04-09 Chong Yidong <cyd@gnu.org>
13111 * eval.c (Fuser_variable_p, user_variable_p_eh)

13116 * minibuf.c (Fread_variable): Callers changed.
13118 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13120 * xdisp.c (set_cursor_from_row): If the display string appears in
13121 the buffer at position that is closer to point than the position
13122 after the display string, display the cursor on the first glyph of
13123 the display string. Fixes cursor display when a 'display' text
13124 property immediately follows invisible text. (Bug#11094)
13126 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13128 composite.c: use 'double' consistently
13129 * composite.c (get_composition_id): Use 'double' consistently
13130 instead of converting 'float' to 'double' and vice versa; this is
13131 easier to understand and avoids a GCC warning.
13133 2012-04-09 Glenn Morris <rgm@gnu.org>
13135 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13136 preparation for dumping it with emacs. (Bug#4789)

13179 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13180 [!WINDOWSNT]: New macros.
13181 (init_libxml2_functions, libxml2_loaded_p): New functions.
13182 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13183 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13184 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13185 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13187 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13188 Call init_libxml2_functions before calling libxml2 functions.
13189 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13191 * emacs.c: Don't include libxml/parser.h.
13192 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13193 xmlCleanupParser directly.
13195 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13197 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13199 * indent.c (Fvertical_motion): If there is a display string at
13200 point, use it.vpos to compute how many lines to backtrack after
13201 move_it_to point. (Bug#11133)
13203 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13205 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13206 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13207 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13208 macros related to unification of CJK characters. For the details,
13209 see the discussion following the message here:
13210 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

13223 * w32menu.c (is_simple_dialog): Properly check lisp types.
13226 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13228 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13229 position we get to after a call to move_it_to fails the
13230 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13231 only if we wind up in a string from display property. (Bug#11063)
13233 * window.c (Fdelete_other_windows_internal): Invalidate the row
13234 and column information about mouse highlight, so that redisplay
13235 restores it after reallocating the glyph matrices. (Bug#7464)
13237 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13238 string comes from a `display' text property, use the buffer
13239 position of that property as if we actually saw that position in
13241 (move_it_by_lines): Remove the assertion that
13242 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13243 violated when there's a before-string at the beginning of a line.
13246 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13248 * xdisp.c (append_space_for_newline): If the default face was

13250 (extend_face_to_end_of_line): Use the remapped default face for
13251 extending the face to the end of the line.
13252 (display_line): Call extend_face_to_end_of_line when the default
13253 face was remapped. (Bug#11068)
13255 2012-03-29 Eli Zaretskii <eliz@gnu.org>

13263 2012-03-27 Glenn Morris <rgm@gnu.org>
13265 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13268 2012-03-26 Kenichi Handa <handa@m17n.org>
13270 * dispextern.h (struct glyph): Fix previous change. Change the
13271 bit length of glyphless.ch to 25 (Bug#11082).

13275 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13276 (command_loop_1): Use it; inhibit selection update for
13277 handle-select-window too (Bug#8996).
13279 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13281 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13283 2012-03-25 Kenichi Handa <handa@m17n.org>
13285 * dispextern.h (struct glyph): Change the bit length of
13286 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13288 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13290 * s/ms-w32.h (tzname): Include time.h before redirecting to
13291 _tzname. Fixes the MSVC build. (Bug#9960)
13293 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13295 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13298 * xterm.c (XTread_socket): Only modify handling_signal if
13299 !SYNC_INPUT. (Bug#11080)
13301 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13303 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13304 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13305 when fetching a multibyte character consumes more bytes than
13306 CHAR_BYTES returns, due to unification of CJK characters in
13307 string_char. (Bug#11073)
13309 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13311 * process.c (wait_reading_process_output): Handle pty disconnect
13312 by refraining from sending oneself a SIGCHLD (bug#10933).

13341 it fit in a valid range (Bug#11003).
13343 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13345 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13346 that is not from display property, accept the row as a "cursor
13347 row" if one of the string's character has a non-nil `cursor'
13348 property. Fixes cursor positioning when there are newlines in
13349 overlay strings, e.g. in icomplete.el. (Bug#11035)
13351 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13353 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13355 2012-03-12 Chong Yidong <cyd@gnu.org>
13357 * eval.c (inhibit_lisp_code): Rename from
13358 inhibit_window_configuration_change_hook; move from window.c.
13360 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13361 * window.c (run_window_configuration_change_hook)
13362 (syms_of_window): Callers changed.

13382 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13385 2012-03-03 Glenn Morris <rgm@gnu.org>
13387 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13389 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13391 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13392 position past the first glyph_row that ends at ZV. (Bug#10902)
13393 (redisplay_window, next_element_from_string): Fix typos in
13395 (redisplay_window): Pass to move_it_vertically the margin in
13396 pixels, not in screen lines.
13398 2012-03-02 Glenn Morris <rgm@gnu.org>
13400 * buffer.c (buffer-list-update-hook): Doc fix.
13402 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13404 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13405 push_it before setting up the iterator for the first overlay
13406 string, even if we have an empty string loaded.
13407 (next_overlay_string): If there's an empty string on the iterator
13408 stack, pop the stack. (Bug#10903)
13410 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13412 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13413 Suggested by Stefan Monnier in
13414 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13415 * alloc.c (widen_to_Lisp_Object): New static function.
13416 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13417 and widening them to Lisp_Objects. This would work even if
13418 USE_LSB_TAG is defined and wide integers are used, which might
13419 happen in a future version of Emacs.
13421 2012-02-25 Chong Yidong <cyd@gnu.org>
13423 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13426 * xselect.c (Fx_selection_exists_p): Doc fix.
13427 (x_clipboard_manager_save_all): Print an informative message
13428 before saving to clipboard manager.
13430 2012-02-24 Chong Yidong <cyd@gnu.org>
13432 * keyboard.c (process_special_events): Handle all X selection
13433 requests in kbd_buffer, not just the next one (Bug#8869).
13435 2012-02-23 Chong Yidong <cyd@gnu.org>
13437 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13438 call when setting menu-bar-lines and tool-bar-lines parameters.
13439 (unwind_create_frame_1): New helper function.
13441 * window.c (inhibit_window_configuration_change_hook): New var.

13452 * fileio.c (Vfile_name_handler_alist): Doc fix.
13454 * buffer.c (Fget_file_buffer): Protect against invalid file
13455 handler return value.
13457 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13459 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13460 when computing $valmask.
13462 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13463 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13464 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13465 It's useless in that case, and it can cause problems on hosts
13466 that allocate halves of EMACS_INT values separately.
13467 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13468 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13469 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13470 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13471 it avoids undefined behavior on hosts where shifting right by more
13472 than the word width has undefined behavior.
13474 2012-02-19 Chong Yidong <cyd@gnu.org>
13476 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13477 (Funhandled_file_name_directory, Ffile_name_as_directory)
13478 (Fdirectory_file_name, Fexpand_file_name)
13479 (Fsubstitute_in_file_name): Protect against invalid file handler
13480 return values (Bug#10845).
13482 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13484 * .gdbinit (pitx): Fix incorrect references to fields of the

13494 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13496 2012-02-15 Chong Yidong <cyd@gnu.org>
13498 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13499 marked as special. Also, starting docstrings with * is obsolete.

13514 2012-02-12 Chong Yidong <cyd@gnu.org>
13516 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13517 as that creates a dangerous corner case.
13519 * window.c (Fdelete_window_internal): Invalidate the mouse
13520 highlight (Bug#9904).
13522 2012-02-12 Glenn Morris <rgm@gnu.org>

13527 * nsselect.m (Fx_own_selection_internal)
13528 (Fx_disown_selection_internal, Fx_selection_exists_p)
13529 (Fx_selection_owner_p, Fx_get_selection_internal):
13530 Sync docs and argument specs with the xselect.c versions.
13532 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

13552 2012-02-07 Chong Yidong <cyd@gnu.org>
13554 * buffer.c (Fbuffer_local_variables)
13555 (buffer_lisp_local_variables): Handle unbound vars correctly;
13556 don't let Qunbound leak into Lisp.
13558 2012-02-07 Glenn Morris <rgm@gnu.org>
13560 * image.c (Fimagemagick_types): Doc fix.
13562 * image.c (imagemagick-render-type): Change it from a lisp object
13563 to an integer. Move the doc here from the lisp manual.

13583 Include --enable-checking, if specified, in the return value.
13585 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13587 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols

13592 * keyboard.c (adjust_point_for_property): Don't position point
13593 before BEGV. (Bug#10696)
13595 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13597 Handle overflow when computing char display width (Bug#9496).
13598 * character.c (char_width): Return EMACS_INT, not int.
13599 (char_width, c_string_width): Check for overflow when
13600 computing the width; this is possible now that individual
13601 characters can have unbounded width. Problem introduced
13602 by merge from Emacs 23 on 2012-01-19.
13604 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13626 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13628 (x_produce_glyphs): If the component of a composition is a null
13629 string, set it->pixel_width to 1 to avoid zero-width glyph.
13631 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13633 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13634 first 2 arguments are identical. This makes inserting large
13635 output from a subprocess an order of magnitude faster on
13636 MS-Windows, where all sbrk'ed memory is always contiguous.
13638 2012-01-31 Glenn Morris <rgm@gnu.org>

13718 he end column for display of highlight that ends on a newline
13721 2012-01-11 Glenn Morris <rgm@gnu.org>
13723 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

13728 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
13730 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
13731 Update template values to be closer to their typical values these days.
13733 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13735 * xdisp.c (rows_from_pos_range): Accept additional argument
13736 DISP_STRING, and accept any glyph in a row whose object is that
13737 string as eligible for mouse highlight. Fixes mouse highlight of

14251 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14252 Otherwise, valgrind does not work on some platforms.
14253 Problem reported by Andreas Schwab in
14254 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14255 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14256 is set, removing the need for VIRT_ADDRESS_VARIES.
14257 (PURE_P): Use a more-efficient implementation that needs just one
14258 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14259 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14260 to 4 (xorl, subq, cmpq, setbe).
14261 * alloc.c (pure): Always extern now, since that's the
14262 VIRT_ADDR_VARIES behavior.
14263 (PURE_POINTER_P): Use a single comparison, not two, for
14264 consistency with the new puresize.h.
14265 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14266 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14274 behave as if the cursor position were at the window margin.
14276 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14277 and the cursor position is out of bounds, behave as if the cursor
14278 position were at the window margin. (Bug#10075)
14280 2011-11-18 Chong Yidong <cyd@gnu.org>
14282 * window.c (Fwindow_combination_limit): Make first argument

14304 compute_line_metrics.
14305 (compute_line_metrics): Call row_hash, instead of computing the
14308 * dispnew.c (verify_row_hash): Call row_hash for computing the
14309 hash code of a row, instead of duplicating code from xdisp.c.
14311 * dispextern.h (row_hash): Add prototype.
14313 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

14341 (Fsplit_window_internal, saved_window)
14342 (Fset_window_configuration, save_window_save): Rename all
14343 occurrences of window_nest to window_combination_limit.

14349 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14351 * xdisp.c (display_line): Move the call to
14352 highlight_trailing_whitespace before the call to
14353 compute_line_metrics, since the latter needs to see the final
14354 faces of all the glyphs to compute ROW's hash value.
14355 Fixes assertion violations in row_equal_p. (Bug#10035)
14357 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14359 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14360 just return (bug#10044).
14362 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14364 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14365 with user-defined heap size. Bump the default size of the temacs
14366 heap to 27MB, to avoid memory warning when running temacs.

14369 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14370 current_matrix and desired_matrix. (Bug#9990)
14371 (verify_row_hash) [XASSERTS]: New function.

14418 Avoid some portability problems by eschewing 'extern inline' functions.
14419 The trivial performance wins aren't worth the portability hassles; see
14420 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14422 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14496 (window_box_width, window_box_left, window_box_left_offset)
14497 (window_box_right, window_box_right_offset): Declare extern.
14498 Otherwise, these inline functions do not conform to C99 and
14499 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14500 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14501 * intervals.c (adjust_intervals_for_insertion)

14504 (static_offset_intervals): Remove.
14505 (offset_intervals): Rewrite using the old contents of
14506 static_offset_intervals. The old version didn't conform to C99

14664 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14666 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14668 * xterm.c: Declare x_handle_net_wm_state to return int.
14669 (handle_one_xevent): Check if we are iconified but don't have
14670 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14671 (get_current_wm_state): Return non-zero if not hidden,
14672 check for _NET_WM_STATE_HIDDEN (Bug#9893).
14673 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
14674 (x_handle_net_wm_state): Return what get_current_wm_state returns.
14675 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
14677 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14679 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14680 so that this new function doesn't get optimized away by a
14681 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14683 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14685 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14687 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14689 Fix the `xbytecode' command.
14690 * .gdbinit (xprintbytestr): New command.
14691 (xwhichsymbols): Rename from `which'; all callers changed.
14692 (xbytecode): Print the byte-code string as well.
14694 2011-10-29 Kim Storm <storm@cua.dk>
14696 * alloc.c (which_symbols): New function.
14698 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14700 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14703 2011-10-29 Glenn Morris <rgm@gnu.org>
14705 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14706 Not clear what it was for, and it causes various bugs. (Bug#9839)
14708 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14710 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14711 possible random value that matches one of those tested as
14712 condition to clear the mouse face.
14714 2011-10-28 Chong Yidong <cyd@gnu.org>
14716 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14718 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14720 * window.c (make_window): Initialize phys_cursor_on_p.
14722 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14724 * lisp.h (struct Lisp_Symbol): Update comments.
14726 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14728 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14730 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14732 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14733 <oslsachem@gmail.com> for helping to debug this.
14735 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14736 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14737 (g_b_init_get_glyph_outline_w): New static variables.
14738 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14739 (GetGlyphOutlineW_Proc): New typedefs.
14740 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14741 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14743 (w32font_open_internal, compute_metrics):
14744 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14745 instead of calling the "wide" APIs directly.
14747 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14749 * w32.h (syms_of_w32font): Add prototype.
14751 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14753 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14754 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14755 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14756 (Fmove_to_window_line): Doc fix.
14758 2011-10-27 Chong Yidong <cyd@gnu.org>
14760 * process.c (make_process): Set gnutls_state to NULL.
14762 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14763 non-NULL, regardless of GNUTLS_INITSTAGE.
14764 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14765 an error. Set process slots as soon as we allocate them.
14767 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14769 2011-10-27 Chong Yidong <cyd@gnu.org>
14771 * gnutls.c (emacs_gnutls_deinit): New function.
14772 Deallocate credentials structures as well as calling gnutls_deinit.
14773 (Fgnutls_deinit, Fgnutls_boot): Use it.
14775 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14776 (deactivate_process): Call emacs_gnutls_deinit.
14778 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14780 * image.c (x_create_x_image_and_pixmap):
14781 * w32.c (sys_rename, w32_delayed_load):
14782 * w32font.c (fill_in_logfont):
14783 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14785 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14787 * w32fns.c (w32_default_color_map): New function,
14788 extracted from Fw32_default_color_map.
14789 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14791 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14793 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14795 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14797 * keyboard.c (test_undefined): New function (bug#9751).
14798 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14800 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14802 * sysdep.c (init_sys_modes): Fix the check for the controlling
14803 terminal (Bug#6649).
14805 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14807 * dispextern.h (struct bidi_it): New member next_en_type.
14809 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14810 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14811 current character, check also for next_en_type being WEAK_EN.
14812 (bidi_resolve_weak): Don't enter the expensive loop if the current
14813 position is before next_en_pos. Record the bidi type of the first
14814 non-ET, non-BN character we find, in addition to its position.
14815 (bidi_level_of_next_char): Invalidate next_en_type when
14816 next_en_pos is over-stepped.
14818 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14820 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14821 * editfns.c: Rewrite current-time-zone so that it invokes
14822 the equivalent of (format-time-string "%Z") to get the time zone name.
14823 This fixes a bug when the time zone name contains characters that
14824 need converting from the system time locale to Emacs internal format.
14825 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14826 that patch fixed format-time-string to do the conversion, but
14827 I forgot to fix current-time-zone.
14828 (format_time_string): New function, containing most of
14829 what Fformat_time_string used to contain.
14830 (Fformat_time_string): Rewrite in terms of format_time_string.
14831 This doesn't change this function's behavior.
14832 (current-time-zone): Rewrite to use format_time_string.
14833 This fixes the bug reported by Michael Schierl in
14834 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14835 Jason Rumney's 2007-06-07 change worked around this bug, but
14837 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14839 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14841 * xdisp.c (start_display): If the character at POS is displayed
14842 via a display vector, reset IT->current.dpvec_index to zero.
14843 (try_window_reusing_current_matrix): If a line ends in a display
14844 vector or the next line starts in a display vector, continue
14845 redrawing the window even though the character position of
14846 start_row was reached.
14849 2011-10-18 Chong Yidong <cyd@gnu.org>
14851 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14852 with nobreak-char-display too.
14854 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14856 Fix part 3 of bug#9771.
14857 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14858 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14859 non-neutral characters if the current character is a paragraph
14860 separator (a.k.a. Newline). This avoids running the same
14861 expensive loop twice, once when we consume the preceding newline
14862 and the other time when the line actually needs to be displayed.
14863 Avoid the loop when we see neutrals on the base embedding level
14864 following a character whose directionality is the same as the
14865 paragraph's. This avoids running the expensive loop when a line
14866 ends in a long sequence of neutrals, like control characters.
14867 Add assertion against STRONG_AL type. Slightly rearrange code
14868 that determines the type of a neutral given the first non-neutral
14870 (bidi_level_of_next_char): Set next_en_pos to zero when
14871 invalidating its info.
14873 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14875 * xdisp.c (push_display_prop): Determine whether to record string
14876 or buffer position by IT->string, not by IT->method. Allow
14877 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14878 (move_it_vertically_backward): Don't look for character position
14879 immediately after the newline when in a continuation line.
14882 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14884 * window.c (coordinates_in_window): Rewrite and delabelize
14885 vertical border check. (Bug#5357) (Bug#9618)
14887 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14889 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14890 errors in XSetWindowBorder (bug#9310).
14892 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14894 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14895 avoid crash when xmalloc overrun checking is enabled.
14897 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14899 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14900 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14901 cursor motion with <left> and <right> arrow keys.
14903 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14904 some callers set that themselves.
14906 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14908 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14909 display string and the previous row comes from the same string and
14910 is empty. (Bug#9739) (Bug#9738)
14912 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14914 * doc.c (get_doc_string): Encode file name (bug#9735).
14916 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14918 * bidi.c (bidi_level_of_next_char):
14919 * xdisp.c (get_visually_first_element): Remove old incorrect
14920 comments regarding the Unicode Line Separator character.
14922 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14924 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14926 * alloc.c (Fgc_status): Do not access beyond zombies array
14927 boundary if nzombies > MAX_ZOMBIES.
14928 * alloc.c (dump_zombies): Add missing format specifier.
14930 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14932 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14933 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14935 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14936 Some packages use them to denote characters with modifiers.
14938 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14940 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14941 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14942 matching a pp-number. Rename parameter var to var1.
14944 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14946 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14948 2011-10-08 Glenn Morris <rgm@gnu.org>
14950 * callint.c (Fcall_interactively): Give a more explicit error for the
14951 'c' case with a non-character input. (Bug#8479)
14953 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14955 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14957 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14958 lines that are hscrolled on the left.
14960 * dispnew.c (buffer_posn_from_coords): Account for a possible
14961 presence of header-line. (Bug#4426)
14963 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14965 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14966 Don't advertise functionality which we discourage or doesn't work.
14968 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14970 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14971 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14972 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14973 this makes Emacs dump core during garbage collection on rare
14974 occasions. sizeof is obviously inferior to offsetof here, so
14975 stick with offsetof.
14976 (GC_POINTER_ALIGNMENT): New macro.
14977 (mark_memory): Omit 3rd (offset) arg; caller changed.
14978 Don't assume EMACS_INT alignment is the same as pointer alignment.
14980 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14982 * keyboard.c (read_key_sequence_remapped): New var.
14983 (read_key_sequence): Compute remapping in the right buffer.
14984 (command_loop_1): Use read_key_sequence's remapping directly.
14986 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14988 * dired.c (file_name_completion): Don't expand file name.
14989 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14990 before checking file name handler.
14992 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14993 they've been requested explicitly (bug#9591).
14995 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14997 * keymap.c (Fsingle_key_description): Use make_specified_string
14998 instead of build_string to build string from push_key_description.
15001 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15003 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15004 This fixes a Y2038 bug on 64-bit hosts.
15005 * buffer.c (reset_buffer):
15006 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15007 (Fclear_buffer_auto_save_failure):
15008 Use 0, not -1, to represent an unset failure time, since time_t
15009 might not be signed.
15011 Remove dependency on glibc malloc internals.
15012 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15013 Move back here from lisp.h, but with their new implementations.
15014 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15015 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15016 * charset.c (charset_table_init): New static var.
15017 (syms_of_charset): Use it instead of xmalloc. This removes a
15018 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15019 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15020 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15021 Move back to alloc.c.
15022 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15023 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15025 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15027 * nsterm.m (windowDidResize): Call x_set_window_size only when
15028 ns_in_resize is true. Otherwise set pixelwidth/height and
15029 call change_frame_size (Bug#9628).
15031 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15033 Port --enable-checking=all to Fedora 14 x86-64.
15034 * charset.c (syms_of_charset): Also account for glibc malloc's
15035 internal overhead when calculating the initial malloc maximum.
15037 Port --enable-checking=all to Fedora 14 x86.
15038 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15040 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15041 (overrun_check_realloc, overrun_check_free):
15042 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15043 That way, xmalloc returns a properly-aligned pointer even if
15044 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15045 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15046 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15047 into account when calculating the initial malloc maximum.
15048 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15049 Move here from alloc.c, so that charset.c can use it too.
15050 Properly align; the old code wasn't right for common 32-bit hosts
15051 when configured with --enable-checking=all.
15052 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15053 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15055 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15057 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15060 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15062 * xdisp.c (compute_display_string_end): If there's no display
15063 string at CHARPOS, return -1.
15065 * bidi.c (bidi_fetch_char): When compute_display_string_end
15066 returns a negative value, treat the character as a normal
15067 character not covered by a display string. (Bug#9624)
15069 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15071 * lread.c (Fread_from_string): Fix typo in docstring.
15073 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15075 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15076 newline, reseat the iterator instead of bidi-iterating there one
15077 character at a time. (Bug#9610)
15078 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15079 TO_CHARPOS if the bidi iterator is at base embedding level.
15081 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15083 * lread.c (readevalloop): Use correct code for NBSP.
15084 (read1): Likewise. (Bug#9608)
15086 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15088 * dbusbind.c (Fdbus_register_signal): When service is not
15089 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15091 2011-09-25 Glenn Morris <rgm@gnu.org>
15093 * buffer.c (truncate-lines): Doc fix.
15095 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15097 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15098 (Fset_window_next_buffers): Doc fix.
15100 2011-09-24 Glenn Morris <rgm@gnu.org>
15102 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15104 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15106 Fix minor problems found by static checking.
15107 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15108 * indent.c (Fvertical_motion): Fix == vs = typo.
15110 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15112 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15113 Default value is now t. Doc fix.
15115 * indent.c (Fvertical_motion): Compute and apply the overshoot
15116 logic when moving up, not only when moving down. Fix the
15117 confusing name and values of the it_overshoot_expected variable;
15118 logic changes accordingly. (Bug#9254) (Bug#9549)
15120 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15121 CHARPOS is covered by a display string which includes newlines.
15122 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15123 is covered by a display string with embedded newlines.
15125 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15127 * dbusbind.c (Fdbus_register_signal): Add match rule to
15128 Vdbus_registered_objects_table. (Bug#9581)
15129 (Fdbus_register_method, Vdbus_registered_objects_table):
15132 2011-09-24 Jim Meyering <meyering@redhat.com>
15134 do not ignore write error for any output size
15135 The previous change was incomplete.
15136 While it makes emacs --batch detect the vast majority of stdout
15137 write failures, errors were still ignored whenever the output size is
15138 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15139 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15140 && echo FAIL: ignored write error
15141 FAIL: ignored write error
15142 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15143 && echo FAIL: ignored write error
15144 FAIL: ignored write error
15145 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15147 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15149 * emacs.c (Fkill_emacs): In noninteractive mode exit
15150 non-successfully if a write error occurred on stdout. (Bug#9574)
15152 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15154 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15157 * dispextern.h (struct it): Update the comment documenting what
15160 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15162 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15163 a display string, extend search for cursor position to end of row.
15164 (find_row_edges): If the row ends in a newline from a display
15165 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15166 Handle the case of a display string with multiple newlines.
15167 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15168 non-empty line. Fixes confusing cursor motion with arrow keys at
15169 the beginning of a line that starts with whitespace.
15171 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15173 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15176 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15178 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15179 boolean (Bug#9154).
15181 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15183 * xdisp.c (display_line): Record maximum and minimum buffer
15184 positions even if no glyphs were produced (e.g., by a zero-width
15185 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15186 buffer positions that will be removed from the glyph row because
15188 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15189 column is beyond frame width: don't subtract 1 "pixel" when
15190 computing width of the stretch.
15191 (reseat_at_next_visible_line_start): Undo the change made on
15192 2011-09-17 that saved paragraph information and restored it after
15193 the call to `reseat'. (Bug#9545)
15195 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15197 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15198 and turn window cursor on if cleared (Bug#9415).
15200 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15202 * search.c (boyer_moore): Take unibyte characters from pattern
15203 literally. (Bug#9458)
15205 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15207 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15209 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15211 Fix minor problem found by static checking.

15213 initialized, to pacify gcc -Wuninitialized.
15215 * fileio.c: Report proper errno when syscall falls.
15216 (Finsert_file_contents): Save and restore errno,
15217 so that report_file_error outputs the correct diagnostic.
15218 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15220 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15222 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15224 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15226 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15227 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15229 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15231 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15232 about the current paragraph and restore it after the call to reseat.
15234 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15235 (bidi_find_paragraph_start): Search back for paragraph beginning
15236 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15237 (bidi_move_to_visually_next): Only trigger paragraph-related
15238 computations when the last character is a newline or at EOB, not
15239 just any NEUTRAL_B. (Bug#9470)
15241 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15242 truncated lines if point is covered by a display string. (Bug#9524)
15244 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15246 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15247 (cons_to_x_long): New function.
15248 (lisp_data_to_selection_data): Use it. Correct the test for
15249 short-versus-long data; it was negated. Break out of vector
15250 loop, for efficiency, when a long datum is discovered.
15252 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15254 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15256 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15258 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15259 GCC PR/17406) by declaring this function with external scope.
15261 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15263 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15264 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15266 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15268 * editfns.c (Fformat): Correctly handle text properties on "%%".

15276 * xdisp.c (get_next_display_element)
15277 (fill_composite_glyph_string): Add comments about special meaning
15278 of TAB characters in a composition.
15280 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15282 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15283 This occurs when processing a multibyte format.
15284 Problem reported by Wolfgang Jenker.
15286 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15288 * xdisp.c (try_cursor_movement): Only check for exact match if
15289 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15291 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15293 Remove unused external symbols.
15294 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15295 * xdisp.c (calc_pixel_width_or_height): Now static.
15296 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15297 * indent.c (check_display_width):
15298 * w32term.c: Fix comment to match code.
15299 * xterm.c, xterm.h (x_catching_errors): Remove.
15301 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15303 * xselect.c: Use signed conversions more consistently (Bug#9498).
15304 (selection_data_to_lisp_data): Assume incoming selection data are
15305 signed integers, not unsigned. This is to be consistent with
15306 outgoing selection data, which was modified to use signed integers
15307 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15308 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15309 expects long, not unsigned long.
15311 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15313 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15314 computation of loop end. Reported by Johan Bockgård
15317 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15319 * frame.c (Fother_visible_frames_p): Function deleted.
15321 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15323 * indent.c (compute_motion): Process display vector front to back
15324 rather than the other way around. (Bug#2496)
15326 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15328 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15330 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15332 * minibuf.c (Fread_from_minibuffer): Doc fix.
15334 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15336 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15337 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15339 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15341 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15342 value for non-existent files.
15344 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15346 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15347 set its "size" to -1. This will set the modtime_size field of
15348 the corresponding buffer to -1, which is what
15349 verify-visited-file-modtime expects for files that do not exist.
15352 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15354 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15356 * lisp.h: ... from here. push_key_description is no longer
15357 defined in keyboard.c, so its declaration should not be in
15358 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15359 logically belongs with push_key_description.
15361 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15363 * buffer.h: Include <sys/types.h> instead of <time.h>.
15364 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15365 Problem reported by Herbert J. Skuhra.
15367 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15369 * xml.c (parse_region): Make the parsing work for
15370 non-comment-starting XML files again (bug#9144).
15372 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15374 * image.c (gif_load): Fix calculation of bottom and right corner.
15377 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15379 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15380 redisplay in small windows.
15382 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15384 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15386 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15388 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15389 Operate on live windows only.
15391 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15393 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15395 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15397 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15398 only under bidi iteration.
15400 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15402 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15404 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15406 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15407 Without this fix, the command to link temacs failed due to an
15408 undefined symbol __builtin_isnan. This is because
15409 /usr/include/iso/math_c99.h #defines isnan(x) to
15410 __builtin_isnan(x), but the bundled gcc, which identifies itself
15411 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15413 * floatfns.c (isnan): #undef, and then #define to a clone of
15415 (Fisnan): Always define, since it's always available now.
15416 (syms_of_floatfns): Always define isnan at the Lisp level.
15418 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15420 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15422 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15424 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15425 The previous code assumed that file offsets (off_t values) fit in
15426 EMACS_INT variables, which is not true on typical 32-bit hosts.
15427 The code messed up by falsely reporting buffer overflow in cases
15428 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15429 when "big" contains more than 2**29 bytes, even though this
15430 inserts just one byte and does not overflow the buffer.
15431 (Finsert_file_contents): Store file offsets as off_t
15432 values, not as EMACS_INT values. Check for overflow when
15433 converting between EMACS_INT and off_t. When checking for
15434 buffer overflow or for overlap, take the offsets into account.
15435 Don't use EMACS_INT for small values where int suffices.
15436 When checking for overlap, fix a typo: ZV was used where
15437 ZV_BYTE was intended.
15438 (Fwrite_region): Don't assume off_t fits into 'long'.
15439 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15441 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15443 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15445 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15447 sprintf-related integer and memory overflow issues (Bug#9412).
15449 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15450 (esprintf, exprintf, evxprintf): New functions.
15451 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15452 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15453 (modify_event_symbol): Do not assume that the length of
15454 name_alist_or_stem is safe to alloca and fits in int.
15455 (Fexecute_extended_command): Likewise for function name and binding.
15456 (Frecursion_depth): Wrap around reliably on integer overflow.
15457 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15458 since some callers pass EMACS_INT values.
15459 (Fsingle_key_description): Don't crash if symbol name contains more
15460 than MAX_ALLOCA bytes.
15461 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15462 (get_minibuffer): Arg is now EMACS_INT, not int.
15463 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15464 (esprintf, exprintf, evxprintf): New decls.
15465 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15467 * dbusbind.c (signature_cat): New function.
15468 (xd_signature, Fdbus_register_signal):
15469 Do not overrun buffer; instead, report string overflow.
15471 * dispnew.c (add_window_display_history): Don't overrun buffer.
15472 Truncate instead; this is OK since it's just a log.
15474 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15475 even if the time zone offset is outlandishly large.
15476 Don't mishandle offset == INT_MIN.
15478 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15479 when creating daemon; the previous buffer-overflow check was incorrect.
15481 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15482 which has the guts of the old verror function.
15484 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15485 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15487 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15488 (font_unparse_xlfd): Don't blindly alloca long strings.
15489 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15490 fits in int, when using sprintf. Use single snprintf to count
15491 length of string rather than counting it via multiple sprintfs;
15492 that's simpler and more reliable.
15493 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15494 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15495 sprintf, in case result does not fit in int.
15497 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15498 (fontset_from_font): Print it.
15500 * frame.c (tty_frame_count): Now printmax_t, not int.
15501 (make_terminal_frame, set_term_frame_name): Print it.
15502 (x_report_frame_params): In X, window IDs are unsigned long,
15503 not signed long, so print them as unsigned.
15504 (validate_x_resource_name): Check for implausibly long names,
15505 and don't assume name length fits in 'int'.
15506 (x_get_resource_string): Don't blindly alloca invocation name;
15507 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15510 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15511 (xg_check_special_colors, xg_set_geometry):
15512 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15514 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15515 Use esprintf, not sprintf, in case result does not fit in int.
15517 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15518 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15519 it as a large positive number.
15520 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15521 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15523 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15524 in case result does not fit in int.
15526 * print.c (float_to_string): Detect width overflow more reliably.
15527 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15528 buffer overrun. Don't assume list length fits in 'int'. Treat
15529 print length of 0 as 0, not as infinity; to be consistent with other
15530 uses of print length in this function. Don't overflow print length
15531 index. Don't assume hash table size fits in 'long', or that
15532 vectorlike size fits in 'unsigned long'.
15534 * process.c (make_process): Use printmax_t, not int, to format
15535 process-name gensyms.
15537 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15539 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15540 to avoid potential buffer overrun.
15542 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15543 if X resource line is longer than 512 bytes.
15545 * xfns.c (x_window): Make sprintf buffer a bit bigger
15546 to avoid potential buffer overrun.
15548 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15550 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15552 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15554 Integer overflow fixes for scrolling, etc.
15555 Without these, Emacs silently mishandles large integers sometimes.
15556 For example, "C-u 4294967297 M-x recenter" was treated as if
15557 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15559 * xdisp.c (try_window_id): Check Emacs fixnum range before
15560 converting to 'int'.
15562 * window.c (window_scroll_line_based, Frecenter):
15563 Check that an Emacs fixnum is in range before assigning it to 'int'.
15564 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15565 values converted from Emacs fixnums.
15566 (Frecenter): Don't wrap around a line count if it is out of 'int'
15567 range; instead, treat it as an extreme value.
15568 (Fset_window_configuration, compare_window_configurations):
15569 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15571 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15572 that can exceed INT_MAX. Check that EMACS_INT value is in range
15573 before assigning it to the (possibly-narrower) index.
15574 (match_limit): Don't assume that a fixnum can fit in 'int'.
15576 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15579 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15580 (Fvertical_motion): Don't wrap around LINES values that don't fit
15581 in 'int'. Instead, treat them as extreme values. This is good
15582 enough for windows, which can't have more than INT_MAX lines anyway.
15584 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15586 * Require libxml/parser.h to avoid compilation warning.
15588 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15590 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15591 since this reportedly can destroy thread storage.
15593 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15595 * syntax.c (find_defun_start): Update all cache variables if
15596 exiting early (Bug#9401).
15598 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15600 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15602 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15603 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15604 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15606 * term.c (tty_append_glyph): New function.
15607 (produce_stretch_glyph): Static function and its prototype deleted.
15609 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15612 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15614 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15615 when checking :margin (Bug#9390).
15616 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15617 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15618 so that the name doesn't mislead. All uses changed.
15620 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15622 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

15628 position beyond to_charpos, if we are scanning backwards.
15629 (move_it_vertically_backward): When DY == 0, make sure we get to
15630 the first character in the line after the newline.
15632 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15634 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15635 (ccl_driver): Do not generate an out-of-range pointer.
15636 (Fccl_execute_on_string): Remove unnecessary check for
15637 integer overflow, noted by Stefan Monnier in
15638 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15639 Remove a FIXME that didn't need fixing.
15640 Simplify the newly-introduced buffer reallocation code.
15642 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15644 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15646 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15648 Integer and memory overflow issues (Bug#9196).
15650 * doc.c (get_doc_string): Rework so that
15651 get_doc_string_buffer_size is the actual buffer size, rather than
15652 being 1 less than the actual buffer size; this makes xpalloc more
15655 * image.c (x_allocate_bitmap_record, cache_image):
15656 * xselect.c (Fx_register_dnd_atom):
15657 Simplify previous changes by using xpalloc.
15659 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15660 since either will do and ptrdiff_t is convenient with xpalloc.

15663 (struct charset_sort_data.priority): Now ptrdiff_t.
15664 (charset_compare): Don't overflow if priorities differ greatly.
15665 (Fsort_charsets): Don't assume list length fits in int.
15666 Check for size-calculation overflow when allocating sort data.
15667 (syms_of_charset): Allocate an initial charset table that is
15668 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15670 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15672 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15673 The actual value is always <= INT_MAX, and leaving it unsigned made
15674 overflow checking harder.
15676 * dispextern.h (struct glyph_matrix.rows_allocated)
15677 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15678 with xpalloc. The values are still always <= INT_MAX.
15680 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15682 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15683 (SAFE_NALLOCA): New macro.

15686 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15687 (set_cache_region, invalidate_region_cache)
15688 (revalidate_region_cache, know_region_cache, region_cache_forward)
15689 (region_cache_backward, pp_cache):
15690 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15691 so that ptrdiff_t * can be passed to xpalloc.
15692 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15693 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15694 (pp_cache): Don't assume cache_len fits in int.
15695 * region-cache.h: Adjust extern decls to match.
15697 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15698 EMACS_INT, since either will do, for xpalloc.
15700 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15701 (xnmalloc, xnrealloc, xpalloc): New functions.
15703 * bidi.c (bidi_shelve_header_size): New constant.
15704 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15705 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15707 * bidi.c (bidi_cache_shrink):
15708 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15710 Don't update size of array until after memory allocation succeeds,
15711 because xmalloc/xrealloc may not return.
15712 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15713 now that we have proper integer overflow checking.
15714 (record_overlay_string, overlay_strings): Catch overflows when
15715 calculating size of overlay_str_buf.
15717 * callproc.c (Fcall_process): Check for size overflow when
15718 calculating size of args2.
15719 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15720 Normally we prefer signed values, but sticking with ptrdiff_t would
15721 require adding more-complicated checks.
15723 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15724 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15725 Redo buffer-overflow calculations to avoid integer overflow.
15726 Add a FIXME comment where memory seems to be over-allocated.
15728 * character.c (Fstring): Check for size-calculation overflow.
15730 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15731 unnecessary integer overflow. Check for size overflow.
15732 (encode_coding_object): Don't update size until xmalloc succeeds.
15734 * composite.c (get_composition_id): Check for overflow in glyph
15735 length calculations.
15737 Integer and memory overflow fixes for display code.
15738 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15739 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

15752 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15753 (get_doc_string): Check for size calculation overflow.
15754 Don't update size until allocation succeeds.
15755 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not

15761 (message_length): Now ptrdiff_t, not int.
15762 (Fmessage_box): Don't update size until allocation succeeds.
15763 Don't assume message length fits in int.
15764 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15766 * emacs.c (main): Do not reallocate argv, since there is a null at
15767 the end that can be overwritten, and this way there's no need to
15768 worry about size-calculation overflow.
15769 (sort_args): Check for size-calculation overflow.
15771 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15773 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15775 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15776 (x_set_scroll_bar_width, x_figure_window_size):
15777 Check for integer overflow.
15778 (x_set_alpha): Do not assume XINT fits in int.
15780 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15781 This is for the members text_lines, text_cols, total_lines, total_cols,
15782 where the system imposes an 'int' limit.
15784 * fringe.c (Fdefine_fringe_bitmap):
15785 Don't update size until alloc works.
15787 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15788 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15790 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15791 Check for size-calculation overflow.
15792 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15793 do, as we prefer signed integers.
15794 (id_to_widget.max_size, id_to_widget.used)
15795 (xg_store_widget_in_map, xg_remove_widget_from_map)
15796 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15797 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15798 Use and return ptrdiff_t, not int.
15799 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15800 * gtkutil.h: Change prototypes to match the above.
15802 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15803 are duplicate now that they've been promoted to lisp.h.
15804 (x_allocate_bitmap_record, x_alloc_image_color)
15805 (make_image_cache, cache_image, xpm_load):
15806 Don't update size until alloc is done.

15819 calculations. Don't update size until allocation succeeds.
15820 Redo calculations to avoid overflow.

15849 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15850 for command line length. Do not attempt to address one before the
15851 beginning of an array, as that's not portable.
15853 * term.c (max_frame_lines): Remove; unused.
15854 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15856 (encode_terminal_code, calculate_costs): Check for size

15892 Don't update size until alloc done.
15894 * xrdb.c (get_environ_db): Don't assume path length fits in int,

15898 (X_LONG_MIN): New macros.
15899 Use them to make the following changes clearer.
15900 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15901 This change doesn't affect the value now, but it may help remind
15902 future maintainers not to raise the value too much later.
15903 (SELECTION_QUANTUM): Remove, replacing with ...
15904 (selection_quantum): ... new function, which avoids overflow.
15906 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15907 assumption that selection length fits in 'int'.

15920 (lisp_data_to_selection_data, x_property_data_to_lisp):

15924 Don't store size until memory allocation succeeds.
15925 (x_get_window_property): Plug memory leak on memory exhaustion.
15926 Don't double-block input; malloc is safe here. Don't assume 2**34
15927 - 4 fits in unsigned long. Add an xassert to check
15928 XGetWindowProperty overflow. Be more careful about overflow
15929 calculations, and distinguish size from memory overflow better.

15931 unsigned int is less than INT_MAX.
15932 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15933 harmful) conversions of unsigned short to int.
15934 (lisp_data_to_selection_data): Don't assume that integers
15935 in the range -65535 through -1 fit in an X unsigned short.
15936 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15937 result parameters unless successful. Rely on cons_to_unsigned
15938 to report problems with elements; the old code wasn't right anyway.
15939 (x_check_property_data): Check for int overflow; we cannot use
15940 a wider type due to X limits.
15941 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

15973 * lisp.h (hash_lookup, hash_put):
15974 * minibuf.c (Ftest_completion):
15975 Use ptrdiff_t for hash table indexes, not int (which is too
15976 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15977 32-bit --with-wide-int hosts).
15979 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15980 Add a FIXME comment about memory leaks.
15981 (syms_of_charset): Don't assume xmalloc returns.

15988 with outlandish widths.
15989 * character.h (sanitize_tab_width): Rename from sanitize_width,
15990 now that we have two such functions. All uses changed.

16004 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16005 Remove unreachable code.
16006 (read_hex, load_charset_map_from_file): Check for integer overflow.
16008 * xterm.c: Don't go over XClientMessageEvent limit.
16009 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16010 (x_send_scroll_bar_event): Likewise. Check that the size does not
16011 exceed limits imposed by XClientMessageEvent, as well as the usual
16012 ptrdiff_t and size_t limits.
16014 * keyboard.c: Overflow, signedness and related fixes.
16015 (make_lispy_movement): Use same integer type in forward decl
16016 that is used in the definition.
16017 (read_key_sequence, keyremap_step):
16018 Change bufsize argument back to int, undoing my 2011-03-30 change.
16019 We prefer signed types, and int is wide enough here.
16020 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16021 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16022 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16023 length, not size_t. Use ptrdiff_t for index, not int.
16024 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16025 possibility of integer overflow.
16027 Overflow, signedness and related fixes for images.
16029 * dispextern.h (struct it.stack[0].u.image.image_id)
16030 (struct_it.image_id, struct image.id, struct image_cache.size)
16031 (struct image_cache.used, struct image_cache.ref_count):

16046 when the callers expect that.
16047 (image_ascent): Redo ascent calculation to avoid int overflow.
16048 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16049 (lookup_image): Remove unnecessary tests.
16050 (xbm_image_p): Locals are now of int, not EMACS_INT,
16051 since parse_image_check makes sure they fit into int.
16052 (png_load, gif_load, svg_load_image):
16053 Prefer int to unsigned where either will do.
16054 (tiff_handler): New function, combining the cores of the
16055 old tiff_error_handler and tiff_warning_handler.
16056 This function is rewritten to use vsnprintf and thereby avoid
16057 stack buffer overflows. It uses only the features of vsnprintf
16058 that are common to both POSIX and native Microsoft.
16059 (tiff_error_handler, tiff_warning_handler): Use it.
16060 (tiff_load, gif_load, imagemagick_load_image):
16061 Don't assume :index value fits in 'int'.
16062 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16063 (imagemagick_load_image): Check that crop parameters fit into
16064 the integer types that MagickCropImage accepts. Don't assume
16065 Vimagemagick_render_type has a nonnegative value. Don't assume
16066 size_t fits in 'long'.
16067 (gs_load): Use printmax_t to print the widest integers possible.
16068 Check for integer overflow when computing image height and width.
16070 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16072 * xdisp.c (redisplay_window): Don't force window start if point

16080 handle_single_display_spec, not just 1 or zero.
16081 (handle_single_display_spec): If the display spec is of the form
16082 `(space ...)', and specifies display in the text area, return 2
16084 (try_cursor_movement): Check for the need to scroll more
16085 accurately, and prefer exact match for point under bidi.
16086 Don't advance `row' beyond the last row of the window.
16088 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16089 into disp_prop; all users changed.
16091 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16092 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16093 for the text covered by the display property.

16103 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16104 buffers, return left-to-right.
16105 (set_cursor_from_row): Consider candidate row a win if its glyph
16106 represents a newline and point is on that newline. Fixes cursor
16107 positioning on the newline at EOL of R2L text within L2R
16108 paragraph, and vice versa.
16109 (try_cursor_movement): Check continued rows, in addition to
16110 continuation rows. Fixes unwarranted scroll when point enters a
16111 continued line of R2L text within an L2R paragraph, or vice versa.
16112 (cursor_row_p): Consider the case of point being equal to
16113 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16114 from the end of a short line to the beginning of a continued line
16115 of R2L text within L2R paragraph.
16116 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16117 composed characters.
16119 * bidi.c (bidi_check_type): Use xassert.
16120 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
16123 2011-08-23 Eli Zaretskii <eliz@gnu.org>

16130 * nsfont.m (ns_otf_to_script): Fix typo.
16132 2011-08-22 Kenichi Handa <handa@m17n.org>
16134 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16135 extra slot even if the purpose is char-code-property-table.
16137 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16139 * xdisp.c (redisplay_window): When computing centering_position,
16140 account for the height of the header line. (Bug#8874)
16142 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16143 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16144 candidate is selected by the mouse, and that candidate has a
16145 composed character under the mouse.
16147 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16148 coordinates reported by pos-visible-in-window-p for a composed
16149 character in column zero.
16151 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16153 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16155 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16157 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16158 consider it a hit if to_charpos is anywhere in the range of the
16159 composed buffer positions.
16161 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16163 * image.c (gif_load): Don't assume that each subimage has the same
16164 dimensions as the base image. Handle disposal method that is
16165 "undefined" by the gif spec (Bug#9335).
16167 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16169 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16172 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16174 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16175 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16176 from an Org mode buffer to a Speedbar frame.
16178 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16179 a composition, take its buffer position from IT->cmp_it.charpos.
16180 Fixes cursor positioning at the beginning of a line that begins
16181 with a composed character.
16183 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16185 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16186 character bidirectional type, use STRONG_L instead. Fixes crashes
16187 in a buffer produced by `describe-categories'.
16189 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16190 members before the level stack, so they would be saved and
16191 restored when copying iterator state. Fixes incorrect reordering
16192 around TABs covered by display properties.
16194 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16196 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16266 * xdisp.c (move_it_in_display_line_to): Don't invoke
16267 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16268 ppos_it. Fixes vertical cursor motion when line beginning is
16269 covered by an image. (Bug#9296)
16271 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16273 * nsterm.h (ns_run_ascript): Declare.

16277 (ns_run_ascript): New function.
16278 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16279 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16280 the event loop. Get status from as_status (Bug#7276).
16282 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16283 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16284 the event loop (Bug#7276).
16286 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

16310 (Fnetwork_interface_list): Allocate in increments of bytes instead
16311 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16312 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16314 (struct ifflag_def): notrailers is smart on OSX.
16315 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16316 Get hardware address with getifaddrs if available.
16318 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16320 * xdisp.c (iterate_out_of_display_property): xassert that
16321 IT->position is set to within IT->object's boundaries. Break from
16322 the loop as soon as EOB is reached; avoids infloops in redisplay

16324 Set IT->current to match the bidi iterator unconditionally.
16325 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16326 entry. Force push_it to save on the stack the current
16327 buffer/string position, to be restored by pop_it. Fix flags in
16328 the iterator structure wrt the object coming from a display
16329 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16330 properties. (Bug#9284)
16332 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16334 * fontset.c (fontset_get_font_group): Add proper type checks.

16347 no-display-properties-and-no-overlays under bidi display.
16348 Set disp_pos in the bidi iterator to avoid searches for display
16349 properties and overlays.

16362 restore_point_unwind (Bug#5984).
16364 2011-08-07 Juri Linkov <juri@jurta.org>
16366 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16367 to show the arg `TIME' instead of `TIMEVAL'.
16369 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16371 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16372 display property strides EOL and includes a newline, as in
16373 longlines-mode. (Bug#9254)
16374 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16375 word-wrap under bidirectional display. (Bug#9224)
16377 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16378 is non-zero, even if the data buffer is NULL. Fixes a crash in
16379 vertical-motion with longlines-mode. (Bug#9254)
16381 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16383 * bidi.c <bidi_cache_total_alloc>: Now static.

16386 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16389 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16390 amount allocated this far in `bidi_cache_total_alloc'.
16391 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16392 non-zero, only free the data buffer without restoring the cache
16393 contents. All callers changed.
16395 * dispextern.h (bidi_unshelve_cache): Update prototype.
16397 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16398 (move_it_in_display_line, move_it_to)
16399 (move_it_vertically_backward, move_it_by_lines): Replace the call
16400 to xfree to an equivalent call to bidi_unshelve_cache.
16401 (move_it_in_display_line_to): Fix logic of returning
16402 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16404 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16406 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16407 came from a string character with a `cursor' property. (Bug#9229)

16458 DISP_PROP_P, and pass it to compute_display_string_pos.
16459 Only handle text covered by a display string if DISP_PROP_P is returned
16460 non-zero. All callers of bidi_fetch_char changed.
16462 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16464 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16466 2010-12-03 Don March <don@ohspite.net>
16468 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16469 last character M-[char] is translated to ESC [char] (bug#7541).
16471 2011-08-02 Kenichi Handa <handa@m17n.org>
16473 * lisp.h (uniprop_table): Extern it.
16475 * chartab.c (uniprop_table): Make it non-static.
16477 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16479 * xdisp.c (forward_to_next_line_start): Accept additional argument
16480 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16482 (reseat_at_next_visible_line_start): Use the bidi iterator state
16483 returned by forward_to_next_line_start to restore the state of
16484 it->bidi_it after backing up to previous newline. (Bug#9212)
16486 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16488 * regex.c (re_comp): Protoize.
16489 (re_exec): Fix return type.
16490 (regexec): Fix type of `ret'. (Bug#9203)
16492 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16494 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16495 This is needed if max-image-size is a floating-point number.
16497 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16499 * print.c (print_object): Print empty symbol as ##.
16501 * lread.c (read1): Read ## as empty symbol.
16503 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16505 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16506 setting frame foreground color (Bug#9175).
16507 (x_set_background_color): Likewise.
16509 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16510 contents (Bug#9176).
16511 (EmacsTooltip -init): Remove bezels and add shadows to
16514 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16515 or scroll bar (Bug#8470).
16517 * nsfont.m (nsfont_open): Remove assignment to voffset and
16518 unnecessary vars hshink, expand, hd, full_height, min_height.
16519 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16521 * nsterm.h (nsfont_info): Remove voffset field.
16523 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16525 Implement strike-through and overline on NextStep (Bug#8863).
16527 * nsfont.m (nsfont_open): Use underline position provided by font,
16528 instead of hard-coded value of 2.
16529 (nsfont_draw): Call ns_draw_text_decoration instead.
16531 * nsterm.h: Add declaration for ns_draw_text_decoration.
16533 * nsterm.m (ns_draw_text_decoration): New function for drawing
16534 underline, overline, and strike-through.
16535 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16536 ns_draw_text_decoration. Change treatment of cursor drawing to
16537 accommodate underlining, etc.
16539 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16541 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16544 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16546 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16547 Without this fix, if a signal arrives just after memory fills up,
16548 'malloc' might be invoked reentrantly.
16550 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16551 In other words, assume that every image size is allowed, on non-X
16552 hosts. This assumption is probably wrong, but it lets Emacs compile.
16554 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16556 * regex.c (re_iswctype): Convert return values to boolean.
16558 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16560 * xdisp.c (compute_display_string_pos): Don't use cached display
16561 string position if the buffer had its restriction changed.
16564 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16566 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16568 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16570 Integer signedness and overflow and related fixes. (Bug#9079)
16572 * bidi.c: Integer size and overflow fixes.
16573 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16574 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16575 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16576 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16577 (bidi_find_other_level_edge):
16578 Use ptrdiff_t instead of EMACS_INT where either will do.
16579 This works better on 32-bit hosts configured --with-wide-int.
16580 (bidi_cache_ensure_space): Check for size-calculation overflow.
16581 Use % rather than repeated addition, for better worst-case speed.
16582 Don't set bidi_cache_size until after xrealloc returns, because it
16584 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16585 (bidi_cache_ensure_space): Also check that the bidi cache size
16586 does not exceed that of the largest Lisp string or buffer. See Eli
16587 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16589 * alloc.c (__malloc_size_t): Remove.
16590 All uses replaced by size_t. See Andreas Schwab's note
16591 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16593 * image.c: Improve checking for integer overflow.
16594 (check_image_size): Assume that f is nonnull, since
16595 it is always nonnull in practice. This is one less thing to
16596 worry about when checking for integer overflow later.
16597 (x_check_image_size): New function, which checks for integer
16598 overflow issues inside X.
16599 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16600 This removes the need for a memory_full check.
16601 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16602 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16603 (xbm_read_bitmap_data): Change locals back to 'int', since
16604 their values must fit in 'int'.
16605 (xpm_load_image, png_load, tiff_load):
16606 Invoke x_create_x_image_and_pixmap earlier,
16607 to avoid much needless work if the image is too large.
16608 (tiff_load): Treat overly large images as if
16609 x_create_x_image_and_pixmap failed, not as malloc failures.
16610 (gs_load): Use x_check_image_size.
16612 * gtkutil.c: Omit integer casts.
16613 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16614 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16616 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16618 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16619 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16620 would wrongly return t on a 64-bit host.
16622 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16623 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16624 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16625 and therefore cause GCC to emit a bogus diagnostic in some cases.
16627 * image.c: Integer signedness and overflow and related fixes.
16628 This is not an exhaustive set of fixes, but it's time to
16629 record what I've got.
16630 (lookup_pixel_color, check_image_size): Remove redundant decls.
16631 (check_image_size): Don't assume that arbitrary EMACS_INT values
16632 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16633 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16634 (tiff_load, imagemagick_load_image):
16635 Check for overflow in size calculations.
16636 (x_create_x_image_and_pixmap): Remove unnecessary test for
16637 xmalloc returning NULL; that can't happen.
16638 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16639 (xpm_color_bucket): Use better integer hashing function.
16640 (xpm_cache_color): Don't possibly over-allocate memory.
16641 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16642 (gif_memory_source):
16643 Use ptrdiff_t, not int or size_t, to record sizes.
16644 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16645 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16646 either works, as we prefer signed integers.
16647 (tiff_read_from_memory, tiff_write_from_memory):
16648 Return tsize_t, not size_t, since that's what the TIFF API wants.
16649 (tiff_read_from_memory): Don't fail simply because the read would
16650 go past EOF; instead, return a short read.
16651 (tiff_load): Omit no-longer-needed casts.
16652 (Fimagemagick_types): Don't assume size fits into 'int'.
16654 Improve hashing quality when configured --with-wide-int.
16655 * fns.c (hash_string): New function, taken from sxhash_string.
16656 Do not discard information about ASCII character case; this
16657 discarding is no longer needed.
16658 (sxhash-string): Use it. Change sig to match it. Caller changed.
16659 * lisp.h: Declare it.
16660 * lread.c (hash_string): Remove, since we now use fns.c's version.
16661 The fns.c version returns a wider integer if --with-wide-int is
16662 specified, so this should help the quality of the hashing a bit.
16664 * emacs.c: Integer overflow minor fix.
16665 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16666 Define only if GNU_LINUX.
16667 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16669 * dispnew.c: Integer signedness and overflow fixes.
16670 Remove unnecessary forward decls, that were a maintenance hassle.
16671 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16673 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16674 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16675 (prepare_desired_row, line_draw_cost):
16676 Use int, not unsigned, where either works.
16677 (save_current_matrix, restore_current_matrix):
16678 Use ptrdiff_t, not size_t, where either works.
16679 (init_display): Check for overflow more accurately, and without
16680 relying on undefined behavior.
16682 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16683 Remove, replacing with the new symbols in lisp.h. All uses changed.
16684 * fileio.c (make_temp_name):
16685 * filelock.c (lock_file_1, lock_file):
16686 * xdisp.c (message_dolog):
16687 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16688 Use pMd etc. instead.
16689 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16690 replacing the pWIDE etc. symbols removed from editfns.c.
16692 * keyboard.h (num_input_events): Now uintmax_t.
16693 This is (very slightly) less likely to mess up due to wraparound.
16696 * buffer.c: Integer signedness fixes.
16697 (alloc_buffer_text, enlarge_buffer_text):
16698 Use ptrdiff_t rather than size_t when either will do, as we prefer
16701 * alloc.c: Integer signedness and overflow fixes.
16702 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16703 (__malloc_size_t): Default to size_t, not to int.
16704 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16705 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16706 Prefer ptrdiff_t to size_t when either would do, as we prefer
16708 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16709 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16710 Now const. Initialize with values that are in range even if char
16712 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16713 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16714 These functions do the right thing with sizes > 2**32.
16715 (check_depth): Now ptrdiff_t, not int.
16716 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16717 Adjust to new way of storing sizes. Check for size overflow bugs
16719 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16720 slightly wrong anyway, as it missed one instance of
16721 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16722 (refill_memory_reserve): Omit needless cast to size_t.
16723 (mark_object_loop_halt): Mark as externally visible.
16725 * xselect.c: Integer signedness and overflow fixes.
16726 (Fx_register_dnd_atom, x_handle_dnd_message):
16727 Use ptrdiff_t, not size_t, since we prefer signed.
16728 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16729 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16730 x_dnd_atoms_size and x_dnd_atoms_length.
16732 * doprnt.c: Prefer signed to unsigned when either works.
16734 * doprnt.c (doprnt):
16736 * xdisp.c (vmessage):
16737 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16738 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16739 prefer signed arithmetic to avoid comparison confusion.
16740 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16741 but is a bit tricky.
16743 Assume freestanding C89 headers, string.h, stdlib.h.
16744 * data.c, doprnt.c, floatfns.c, print.c:
16745 Include float.h unconditionally.
16746 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16747 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16748 * regex.c: Likewise for stddef.h, string.h.
16749 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16750 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16751 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16752 (STDC_HEADERS): Remove obsolete defines.
16753 * sysdep.c: Include limits.h unconditionally.
16755 Assume support for memcmp, memcpy, memmove, memset.
16756 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16757 * regex.c (memcmp, memcpy):
16758 Remove; we assume C89 now.
16760 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16761 (__malloc_safe_bcopy): Remove; no longer needed.
16763 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16764 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16765 well either way, and we prefer signed to unsigned.
16767 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16769 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16770 closes the connection while we're reading (bug#9182).
16772 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16774 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16775 are specified (Bug#9168).
16777 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16779 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16780 Found by GCC static checking and --with-wide-int on a 32-bit host.
16782 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16784 * xdisp.c (compute_display_string_pos): Fix logic of caching
16785 previous display string position. Initialize cached_prev_pos to
16786 -1. Fixes slow-down at the beginning of a buffer.
16788 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16790 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16791 for attrs[LFACE_FONTSET_INDEX].
16793 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16795 * xml.c (parse_region): Remove unused local
16796 that was recently introduced.
16798 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16800 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16801 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16803 * xdisp.c (move_it_in_display_line_to): Record the best matching
16804 position for TO_CHARPOS while scanning the line, and restore it on
16805 exit if none of the characters scanned was an exact match.
16806 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16807 when exact match is impossible due to invisible text, and the
16808 lines are truncated.
16810 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16812 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16815 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16817 Fix a significant slow-down of cursor motion with C-n, C-p,
16818 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16819 auto-repeat under bidi redisplay in fontified buffers.
16820 * xdisp.c (compute_stop_pos_backwards): New function.
16821 (next_element_from_buffer): Call compute_stop_pos_backwards to
16822 find a suitable prev_stop when we find ourselves before
16824 (reseat): Don't look for prev_stop, as that could mean a very long
16826 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16827 <cached_disp_overlay_modiff>: Cache for last found display string
16829 (compute_display_string_pos): Return the cached position if asked
16830 about the same buffer in the same area of character positions, and
16831 the buffer wasn't changed since the time the display string
16832 position was cached.
16834 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16836 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16837 is an integer, which is important for empty lines. (Bug#9149)
16839 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16841 * frame.c (Fmodify_frame_parameters): In tty case, update the
16842 default face if necessary (Bug#4238).
16844 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16846 * editfns.c (Fstring_to_char): No need to explain what a character
16847 is in the docstring (Bug#6576).
16849 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16851 * xml.c (parse_region): Make sure we always return a tree.
16853 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16855 * xml.c (parse_region): If a document contains only comments,
16858 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16860 * xml.c (make_dom): Return comments, too.
16862 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16865 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16866 and the surrounding thread.
16867 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16868 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16869 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16871 * s/openbsd.h (BROKEN_SIGIO): Define.
16872 * unexelf.c (unexec) [__OpenBSD__]:
16873 Don't update the .mdebug section of the Alpha COFF symbol table.
16875 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16877 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16880 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16882 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16883 This fixes some race conditions on the permissions of any newly
16886 * alloc.c (valid_pointer_p): Use pipe, not open.
16887 This fixes some permissions issues when debugging.
16889 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16890 If fchown fails to set both uid and gid, try to set just gid,
16891 as that is sometimes allowed. Adjust the file's mode to eliminate
16892 setuid or setgid bits that are inappropriate if fchown fails.
16894 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16896 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16897 to compare Lisp_Objects.
16898 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16899 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16900 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16902 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16904 * lread.c (read_integer): Unread even EOF character.
16905 (read1): Likewise. Properly record start position of symbol.

16912 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16913 This works around a problem with the previous change to Fcopy_file.
16914 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16915 and without this change, GCC might complain about discarding
16916 fchown's return value.
16918 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16920 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

16943 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16945 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16946 quotes the next character, and doesn't affect other longer
16947 sequences (bug#8935).
16949 * lread.c (syms_of_lread): Clarify that is isn't only
16950 `eval-buffer' and `eval-defun' that's affected by

16961 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16962 (elsz): Now a signed constant, not a size_t var. We prefer signed
16963 types to unsigned, to avoid integer comparison confusion. Without
16964 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16965 "cannot optimize loop, the loop counter may overflow", a symptom
16967 * indent.c (Fvertical_motion): Mark locals as initialized.
16968 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16970 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

17014 the iterator is before prev_stop.
17015 (init_iterator): Initialize bidi_p from the default value of

17060 instead, set the first_elt flag in the bidi iterator, to produce
17062 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17063 (push_display_prop): xassert that we are iterating a buffer.

17067 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17068 correctly. Don't assume unibyte strings are not bidi-reordered.

17496 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17497 New macros, used in the buffer.c change.

17533 Random fixes. E.g., (random) never returned negative values.
17534 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17535 subseconds part to the entropy, as that's a bit more random.
17536 Prefer signed to unsigned, since the signedness doesn't matter and
17537 in general we prefer signed. When given a limit, use a
17538 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17539 latter isn't right if USE_2_TAGS_FOR_INTS.
17540 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17541 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17553 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17554 This is more efficient than Ffile_directory_p and avoids a minor race.

17558 * buffer.c (Foverlay_put): Say what the return value is
17561 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17565 error be more correct.
17567 * fns.c (Frequire): Remove the mention of the .gz files, since

17584 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17585 Also (re)move comments that are misplaced or no longer relevant.

17614 * lread.c (syms_of_lread): Mention single symbols defined by

17686 * eval.c (struct backtrace): Simplify and port the data structure.
17687 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17688 signed bit field, as this assumption is not portable and it makes
17689 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17690 "char debug_on_exit : 1" as this is not portable either; instead,
17691 use the portable "unsigned int debug_on_exit : 1". Remove unused
17692 member evalargs. Remove obsolete comments about cc bombing out.

17784 pending. Suggested by Jan Djärv (Bug#8869).
17786 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
17788 Use gnulib's dup2 module instead of rolling our own.
17789 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17791 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17793 * dispnew.c (scrolling_window): Before scrolling, turn off a
17794 mouse-highlight in the window being scrolled.

17856 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17858 Integer and buffer overflow fixes (Bug#8873).
17860 * print.c (printchar, strout): Check for string overflow.
17861 (PRINTPREPARE, printchar, strout):
17862 Don't set size unless allocation succeeds.
17864 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17865 for sizes. Check for string overflow more accurately.
17866 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17868 * macros.c: Integer and buffer overflow fixes.
17869 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17870 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17871 Use ptrdiff_t, not int, for sizes.
17872 Don't increment bufsize until after realloc succeeds.
17873 Check for size-calculation overflow.
17874 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17876 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17878 * lread.c: Integer overflow fixes.
17879 (read_integer): Radix is now EMACS_INT, not int,
17880 to improve quality of diagnostics for out-of-range radices.
17881 Calculate buffer size correctly for out-of-range radices.
17882 (read1): Check for integer overflow in radices, and in
17883 read-circle numbers.
17884 (read_escape): Avoid int overflow.
17885 (Fload, openp, read_buffer_size, read1)
17886 (substitute_object_recurse, read_vector, read_list, map_obarray):
17887 Use ptrdiff_t, not int, for sizes.

17902 2011-06-22 Leo Liu <sdl.web@gmail.com>
17904 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17905 Move to minibuffer.el.
17907 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17909 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17910 The following patches are for when GLYPH_DEBUG && !XASSERT.
17911 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17912 * dispnew.c (flush_stdout):
17913 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17914 Mark as externally visible.
17915 * dispnew.c (check_window_matrix_pointers): Now static.
17916 * dispnew.c (window_to_frame_vpos):
17917 * xfns.c (unwind_create_frame):
17918 * xterm.c (x_check_font): Remove unused local.
17919 * scroll.c (CHECK_BOUNDS):
17920 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17921 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17922 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17923 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17924 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17926 (debug_method_add): Use va_list and vsprintf rather than relying
17927 on undefined behavior with wrong number of arguments.
17928 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17929 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17930 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17931 since we're not interested in debugging glyphs with old libraries.
17932 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17933 GCC 4.6.0's static checking.
17935 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17937 Integer overflow and signedness fixes (Bug#8873).

17948 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17949 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17951 * xfaces.c (load_pixmap):
17952 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17953 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17954 (.bitmaps_last, struct x_output.icon_bitmap):
17955 Use ptrdiff_t, not int, for bitmap indexes.
17956 (x_allocate_bitmap_record): Check for size overflow.
17957 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17959 Use ptrdiff_t, not int, for overlay counts.
17960 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17961 * editfns.c (overlays_around, get_pos_property):
17962 * textprop.c (get_char_property_and_overlay):
17963 * xdisp.c (next_overlay_change, note_mouse_highlight):
17964 * xfaces.c (face_at_buffer_position):
17965 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17966 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17967 (Fnext_overlay_change, Fprevious_overlay_change)
17968 (mouse_face_overlay_overlaps, Foverlays_in):
17969 Use ptrdiff_t, not int, for sizes.
17970 (overlays_at, overlays_in): Check for size-calculation overflow.
17972 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17974 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17975 (x_session_initialize): Do not assume string length fits in int.
17977 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17978 This is unlikely, but can occur if DPI is outlandish.
17980 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17981 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17983 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17984 * xrdb.c (magic_file_p, search_magic_path):
17985 Omit last arg SUFFIX; it was always 0. All callers changed.
17986 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17988 * xfont.c (xfont_match): Avoid need for strlen.
17990 * xfns.c: Don't assume strlen fits in int.
17991 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17993 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17994 not unsigned long, as we prefer signed integers. All callers changed.
17995 Detect integer overflow in repeat count.
17996 (message_dolog): Don't assume print length fits in 39 bytes.
17997 (display_mode_element): Don't assume strlen fits in int.
17999 * termcap.c: Don't assume sizes fit in int and never overflow.
18000 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18001 (gobble_line): Check for size-calculation overflow.
18003 * minibuf.c (Fread_buffer):
18004 * lread.c (intern, intern_c_string):
18005 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

18009 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18011 * font.c: Don't assume string length fits in int.
18012 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18013 Use ptrdiff_t, not int.
18014 (font_intern_prop): Don't assume string length fits in int.
18015 Don't assume integer property fits in fixnum.
18016 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18018 * filelock.c: Fix some buffer overrun and integer overflow issues.
18019 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18020 Reformulate so as not to need the command string.
18021 Invoke gzip -cd rather than gunzip, as it's more portable.
18022 (lock_info_type, lock_file_1, lock_file):
18023 Don't assume pid_t and time_t fit in unsigned long.
18024 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18025 (current_lock_owner): Prefer signed type for sizes.
18026 Use memcpy, not strncpy, where memcpy is what is really wanted.
18027 Don't assume (via atoi) that time_t and pid_t fit in int.
18028 Check for time_t and/or pid_t out of range, e.g., via a network share.
18029 Don't alloca where an auto var works fine.
18031 * fileio.c: Fix some integer overflow issues.
18032 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18033 Don't assume string length fits in int.
18034 (directory_file_name): Don't assume string length fits in long.
18035 (make_temp_name): Don't assume pid fits in int, or that its print
18036 length is less than 20.
18038 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18040 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18042 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18044 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18045 We prefer signed integers, even for size calculations.
18047 * emacs.c: Don't assume string length fits in 'int'.
18048 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18049 (main): Don't invoke strlen when not needed.
18051 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18052 (XD_DEBUG_MESSAGE): Don't waste a byte.
18054 * callproc.c (getenv_internal_1, getenv_internal)
18055 (Fgetenv_internal):
18056 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18058 * lread.c (invalid_syntax): Omit length argument.
18059 All uses changed. This doesn't fix a bug, but it simplifies the
18060 code away from its former Hollerith-constant appearance, and it's
18061 one less 'int' to worry about when looking at integer-overflow issues.
18062 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18064 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18065 This didn't break anything, but it didn't help either.
18066 It's confusing to put a bogus integer in a place where the actual
18067 value does not matter.
18068 (LIST_END_P): Remove unused macro and its bogus comment.
18069 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18071 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18072 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18074 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18075 We prefer signed types, and the value cannot exceed the EMACS_INT
18076 range anyway (because otherwise the length would not be representable).
18077 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18078 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18079 This avoids a GCC warning when WIDE_EMACS_INT.
18081 * indent.c (sane_tab_width): New function.
18082 (current_column, scan_for_column, Findent_to, position_indentation)
18083 (compute_motion): Use it. This is just for clarity.
18084 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18086 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

18089 * composite.c (composition_gstring_put_cache):
18090 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18092 * editfns.c, insdel.c:
18093 Omit unnecessary forward decls, to simplify future changes.
18095 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18097 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18099 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18100 Use much-faster test for byte-length change.
18101 Don't assume string byte-length fits in 'int'.
18102 Check that character arg fits in 'int'.
18103 (mapcar1): Declare byte as byte, for clarity.
18105 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18107 * fns.c (concat): Catch string overflow earlier.
18108 Do not rely on integer wraparound.
18110 * dispextern.h (struct it.overlay_strings_charpos)
18111 (struct it.selective): Now EMACS_INT, not int.
18112 * xdisp.c (forward_to_next_line_start)
18113 (back_to_previous_visible_line_start)
18114 (reseat_at_next_visible_line_start, next_element_from_buffer):
18115 Don't arbitrarily truncate the value of 'selective' to int.
18117 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18119 * composite.c: Don't truncate sizes to 'int'.
18120 (composition_gstring_p, composition_reseat_it)
18121 (composition_adjust_point): Use EMACS_INT, not int.
18122 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18123 not EMACS_UINT, for indexes.
18125 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18127 * buffer.c: Include <verify.h>.
18128 (struct sortvec.priority, struct sortstr.priority):
18129 Now EMACS_INT, not int.
18130 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18131 (struct sortstr.size, record_overlay_string)
18132 (struct sortstrlist.size, struct sortlist.used):
18133 Don't truncate size to int.
18134 (record_overlay_string): Check for size-calculation overflow.
18135 (init_buffer_once): Check at compile-time, not run-time.
18137 2011-06-22 Jim Meyering <meyering@redhat.com>
18139 Don't leak an XBM-image-sized buffer
18140 * image.c (xbm_load): Free the image buffer after using it.
18142 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18145 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18146 that Sun C diagnosed.
18147 * fns.c (secure_hash): Fix pointer signedness issue.
18148 * intervals.c (static_offset_intervals): New function.
18149 (offset_intervals): Use it.
18151 2011-06-21 Leo Liu <sdl.web@gmail.com>
18154 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18157 * fns.c (secure_hash): Rename from crypto_hash_function and change
18158 the first arg to accept symbols.
18159 (Fsecure_hash): New primitive.
18160 (syms_of_fns): New symbols.
18162 2011-06-20 Deniz Dogan <deniz@dogan.se>
18164 * process.c (Fset_process_buffer): Clarify return value in
18167 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18169 * dispnew.c (add_window_display_history): Use BVAR.
18171 * xdisp.c (debug_method_add): Use BVAR.
18172 (check_window_end, dump_glyph_matrix, dump_glyph)
18173 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18175 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18178 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18179 check till after the cache is created in init_frame_faces.
18181 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18183 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18185 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18187 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18188 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18189 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18191 Improve buffer-overflow checking (Bug#8873).
18192 * fileio.c (Finsert_file_contents):
18193 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18194 Remove the old (too-loose) buffer overflow checks.
18195 They weren't needed, since make_gap checks for buffer overflow.
18196 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18197 The old code merely checked for Emacs fixnum overflow, and relied
18198 on undefined (wraparound) behavior. The new code avoids undefined
18199 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18201 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18202 Tune. Don't use wider integers than needed. Don't use alloca.
18203 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18205 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18207 * insdel.c, lisp.h (buffer_overflow): New function.
18208 (insert_from_buffer_1, replace_range, replace_range_2):
18209 * insdel.c (make_gap_larger):
18210 * editfns.c (Finsert_char):
18211 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18213 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18215 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18217 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18219 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18220 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18222 * fileio.c: Don't assume EMACS_INT fits in off_t.
18223 (emacs_lseek): New static function.
18224 (Finsert_file_contents, Fwrite_region): Use it.
18225 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18227 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18229 * fns.c: Don't overflow int when computing a list length.
18230 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18231 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18232 truncation on 64-bit hosts. Check for QUIT every
18233 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18234 faster and is responsive enough.
18235 (Flength): Report an error instead of overflowing an integer.
18236 (Fsafe_length): Return a float if the value is not representable
18237 as a fixnum. This shouldn't happen except in contrived situations.
18238 (Fnthcdr, Fsort): Don't assume list length fits in int.
18239 (Fcopy_sequence): Don't assume vector length fits in int.
18241 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18242 (header_size, word_size): New constants.
18243 (allocate_vectorlike): Don't check size overflow here.
18244 (allocate_vector): Check it here instead, since this is the only
18245 caller of allocate_vectorlike that could cause overflow.
18246 Check that the new vector's length is representable as a fixnum.
18248 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18249 The previous code was bogus. For example, next_almost_prime (32)
18250 returned 39, which is undesirable as it is a multiple of 3; and
18251 next_almost_prime (24) returned 25, which is a multiple of 5 so
18252 why was the code bothering to check for multiples of 7?
18254 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18256 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18258 Variadic C functions now count arguments with ptrdiff_t.
18259 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18260 Back then I didn't know that the Emacs coding style prefers signed int.
18261 Also, in the meantime I found a few more instances where arguments
18262 were being counted with int, which may truncate counts on 64-bit
18263 machines, or EMACS_INT, which may be unnecessarily wide.
18264 * lisp.h (struct Lisp_Subr.function.aMANY)
18265 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18266 Arg counts are now ptrdiff_t, not size_t.
18267 All variadic functions and their callers changed accordingly.
18268 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18269 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18270 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18271 * callint.c (Fcall_interactively): Check arg count for overflow,
18272 to avoid potential buffer overrun. Use signed char, not 'int',
18273 for 'varies' array, so that we needn't bother to check its size
18274 calculation for overflow.
18275 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18276 * eval.c (apply_lambda):
18277 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18278 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18279 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18281 * callint.c (Fcall_interactively): Don't use index var as event count.
18283 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18284 * mem-limits.h (SIZE): Remove; no longer used.
18286 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18288 Remove unnecessary casts.
18289 * xterm.c (x_term_init):
18290 * xfns.c (x_set_border_pixel):
18291 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18292 These aren't needed now that we assume ANSI C.
18294 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18295 It's more likely to cause problems (due to unsigned overflow)
18298 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18300 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18302 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18304 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18306 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18308 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18310 GLYPH_CODE_FACE returns EMACS_INT, not int.
18311 * dispextern.h (merge_faces):
18312 * xfaces.c (merge_faces):
18313 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18314 Don't assume EMACS_INT fits in int.
18316 * character.h (CHAR_VALID_P): Remove unused parameter.
18317 * fontset.c, lisp.h, xdisp.c: All uses changed.
18319 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18321 * fns.c (concat): Minor tuning based on overflow analysis.
18322 This doesn't fix any bugs. Use int to hold character, instead
18323 of constantly refetching from Emacs object. Use XFASTINT, not
18324 XINT, for value known to be a character. Don't bother comparing
18325 a single byte to 0400, as it's always less.
18327 * floatfns.c (Fexpt):
18328 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18330 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18333 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18335 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18336 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18337 incorrectly succeed when S was a string, because 4294967386 was
18338 truncated before it was used.
18340 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18341 Otherwise, an out-of-range integer could cause undefined behavior
18344 * composite.c: Use int, not EMACS_INT, for characters.
18345 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18346 EMACS_INT, for values that are known to be in character range.
18347 This doesn't fix any bugs but is the usual style inside Emacs and
18348 may generate better code on 32-bit machines.
18350 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18351 This is for reasons similar to the recent CHAR_STRING fix.
18352 * charset.c (Fencode_char): Check that character arg is actually
18353 a character. Pass an int to ENCODE_CHAR.
18354 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18355 wider than 'int', as a compile-time check to prevent future regressions
18358 * character.c (char_string): Remove unnecessary casts.
18360 Make sure a 64-bit char is never passed to CHAR_STRING.
18361 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18362 by silently ignoring the top 32 bits, allowing some values
18363 that were far too large to be valid characters.
18364 * character.h: Include <verify.h>.
18365 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18366 arguments are no wider than unsigned, as a compile-time check
18367 to prevent future regressions in this area.
18369 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18370 (Fsubst_char_in_region):
18372 * xdisp.c (decode_mode_spec_coding):
18373 Adjust to CHAR_STRING's new requirement.
18374 * editfns.c (Finsert_char, Fsubst_char_in_region):
18375 * fns.c (concat): Check that character args are actually
18376 characters. Without this test, these functions did the wrong
18377 thing with wildly out-of-range values on 64-bit hosts.
18379 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18380 These casts should not be needed on 32-bit hosts, either.
18381 * keyboard.c (read_char):
18382 * lread.c (Fload): Remove casts to unsigned.
18384 * lisp.h (UNSIGNED_CMP): New macro.
18385 This fixes comparison bugs on 64-bit hosts.
18386 (ASCII_CHAR_P): Use it.
18387 * casefiddle.c (casify_object):
18388 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18389 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18390 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18391 * dispextern.h (FACE_FROM_ID):
18392 * keyboard.c (read_char): Use UNSIGNED_CMP.
18394 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18395 not to EMACS_INT, to avoid GCC warning.
18397 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18399 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18400 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18401 isn't needed on 32-bit machines.
18403 * buffer.c (Fgenerate_new_buffer_name):
18404 Use EMACS_INT for count, not int.
18405 (advance_to_char_boundary): Return EMACS_INT, not int.
18407 * data.c (Qcompiled_function): Now static.
18409 * window.c (window_body_lines): Now static.
18411 * image.c (gif_load): Rename local to avoid shadowing.
18413 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18414 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18415 * alloc.c (make_save_value): Integer argument is now of type
18416 ptrdiff_t, not int.
18417 (mark_object): Use ptrdiff_t, not int.
18418 * lisp.h (pD): New macro.
18419 * print.c (print_object): Use it.
18421 * alloc.c: Use EMACS_INT, not int, to count objects.
18422 (total_conses, total_markers, total_symbols, total_vector_size)
18423 (total_free_conses, total_free_markers, total_free_symbols)
18424 (total_free_floats, total_floats, total_free_intervals)
18425 (total_intervals, total_strings, total_free_strings):
18426 Now EMACS_INT, not int. All uses changed.
18427 (Fgarbage_collect): Compute overall total using a double, so that
18428 integer overflow is less likely to be a problem. Check for overflow
18429 when converting back to an integer.
18430 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18431 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18432 These were 'int' variables that could overflow on 64-bit hosts;
18433 they were never used, so remove them instead of repairing them.
18434 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18435 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18436 Previously, this ceilinged at INT_MAX, but that doesn't work on
18438 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18440 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18441 (allocate_vectorlike): Check for ptrdiff_t overflow.
18442 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18443 when a (possibly-narrower) signed value would do just as well.
18444 We prefer using signed arithmetic, to avoid comparison confusion.
18446 * alloc.c: Catch some string size overflows that we were missing.
18447 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18448 for convenience in STRING_BYTES_MAX.
18449 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18450 The definition here is exact; the one in lisp.h was approximate.
18451 (allocate_string_data): Check for string overflow. This catches
18452 some instances we weren't catching before. Also, it catches
18453 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18454 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18455 and ptrdiff_t and EMACS_INT are both 64 bits.
18457 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18458 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18459 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18461 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18463 * alloc.c (Fmake_string): Check for out-of-range init.
18465 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18467 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18469 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18471 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18472 xg_get_default_scrollbar_width.
18474 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18475 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18476 (style_changed_cb): Call update_theme_scrollbar_width and call
18477 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18478 all frames (Bug#8505).
18479 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18480 Call gtk_window_set_resizable if HAVE_GTK3.
18481 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18482 and height if HAVE_GTK3 (Bug#8505).
18483 (scroll_bar_width_for_theme): New variable.
18484 (update_theme_scrollbar_width): New function.
18485 (xg_get_default_scrollbar_width): Move code to
18486 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18487 (xg_initialize): Call update_theme_scrollbar_width.
18489 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18491 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18493 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18495 * frame.c (make_frame): Call other_buffer_safely instead of
18498 * window.c (temp_output_buffer_show): Call display_buffer with
18499 second argument Vtemp_buffer_show_specifiers and reset latter
18500 immediately after the call.
18501 (Vtemp_buffer_show_specifiers): New variable.
18502 (auto_window_vscroll_p, next_screen_context_lines)
18503 (Vscroll_preserve_screen_position): Remove leading asterisks from
18506 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18508 Fix minor problems found by GCC 4.6.0 static checking.
18509 * buffer.c (Qclone_number): Remove for now, as it's unused.
18510 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18511 (record_buffer): Remove unused local.
18512 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18513 (set_frame_buffer_list): Remove; unused.
18514 * frame.h (other_visible_frames): Remove decl.
18515 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18516 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18517 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18519 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18520 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18521 Define only if HAVE_GPM.
18522 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18523 (update_hints_inhibit): Remove; never set. All uses removed.
18524 * widgetprv.h (emacsFrameClassRec): Remove decl.
18525 * window.c (delete_deletable_window): Now returns void, since it
18526 wasn't returning anything.
18527 (compare_window_configurations): Remove unused locals.
18528 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18529 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18530 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18531 the same widths as pointers. This follows up on the 2011-05-06 patch.
18532 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18533 * xterm.h: Likewise.

18539 (LISP_H): Add lib/intprops.h.
18541 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18543 * image.c (gif_load): Add animation frame delay to the metadata.
18544 (syms_of_image): Use DEFSYM. New symbol `delay'.
18546 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18548 * window.c (delete_deletable_window): Re-add.
18549 (Fset_window_configuration): Rewrite to handle dead buffers and
18550 consequently deletable windows.
18551 (window_tree, Fwindow_tree): Remove. Supply functionality in
18553 (compare_window_configurations): Simplify code.
18555 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18557 * image.c (imagemagick_load_image): Fix type mismatch.
18558 (Fimagemagick_types): Likewise.
18560 * window.h (replace_buffer_in_windows): Declare.
18562 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18564 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18565 Qclone_number. Remove external declaration of Qdelete_window.
18566 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18568 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18569 Run Qbuffer_list_update_hook if allowed.
18570 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18571 buffer list implementation.
18572 (other_buffer_safely): New function.
18573 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18574 calls to replace_buffer_in_windows and
18575 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18577 (record_buffer): Inhibit quitting and rewrite using quittable
18578 functions. Run Qbuffer_list_update_hook if allowed.
18579 (Frecord_buffer, Funrecord_buffer): New functions.
18580 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18581 Move switch-to-buffer to window.el.
18582 (bury-buffer): Move to window.el.
18583 (Vbuffer_list_update_hook): New variable.
18585 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18588 * window.h (resize_frame_windows): Move up in code.
18589 (Fwindow_frame): Remove EXFUN.
18590 (replace_buffer_in_all_windows): Remove prototype.
18591 (replace_buffer_in_windows_safely): Add prototype.
18593 * window.c: Declare Qdelete_window static again. Move down
18594 declaration of select_count.
18595 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18596 (Fother_window): Move to window.el.
18597 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18598 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18599 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18601 (replace_buffer_in_windows): Implement by calling
18602 Qreplace_buffer_in_windows.
18603 (replace_buffer_in_all_windows): Remove with some functionality
18604 moved into replace_buffer_in_windows_safely.
18605 (replace_buffer_in_windows_safely): New function.
18606 (select_window_norecord, select_frame_norecord): Move in front
18607 of run_window_configuration_change_hook. Remove now obsolete
18609 (Fset_window_buffer): Rewrite doc-string.
18610 Call Qrecord_window_buffer.
18611 (keys_of_window): Move binding for other-window to window.el.
18613 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18615 * dispextern.h (struct image): Replace data member, whose int_val
18616 and ptr_val fields were not used by anything, with a single
18619 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18620 (gif_clear_image, gif_load, imagemagick_load_image)

19099 * gnutls.c: Use Emacs's memory allocators.
19100 Without this change, the gnutls library would invoke malloc etc.
19101 directly, which causes problems on non-SYNC_INPUT hosts, and which
19102 runs afoul of improving memory_full behavior. (Bug#8761)
19103 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19104 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19105 xfree instead of the default malloc, realloc, free.
19106 (Fgnutls_boot): No need to check for memory allocation failure,
19107 since xmalloc does that for us.
19109 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19110 * category.c (hash_get_category_set):
19111 * ccl.c (ccl_driver):
19112 * charset.c (Fdefine_charset_internal):
19113 * charset.h (struct charset.hash_index):
19114 * composite.c (get_composition_id, gstring_lookup_cache)
19115 (composition_gstring_put_cache):
19116 * composite.h (struct composition.hash_index):
19117 * dispextern.h (struct image.hash):
19118 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19119 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
19120 (hashfn_equal, hashfn_user_defined, make_hash_table)

19122 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19123 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19124 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19125 * image.c (make_image, search_image_cache, lookup_image)
19126 (xpm_put_color_table_h):
19127 * lisp.h (struct Lisp_Hash_Table):
19128 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19129 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19130 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19131 * alloc.c (allocate_vectorlike):
19132 Check for overflow in vector size calculations.
19133 * ccl.c (ccl_driver):
19134 Check for overflow when converting EMACS_INT to int.
19135 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19136 need to be updated by these changes.
19137 * fns.c (make_hash_table, maybe_resize_hash_table):
19138 Check for integer overflow with large hash tables.
19139 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19140 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19141 (SXHASH_REDUCE): New macro.
19142 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19143 Use it instead of discarding useful hash info with large hash values.
19144 (sxhash_float): New function.
19145 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19146 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19147 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19148 Rewrite to use FIXNUM_BITS, as this simplifies things.
19149 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19150 Adjust signatures to match updated version of code.
19151 (consing_since_gc): Now EMACS_INT, since a single hash table can
19152 use more than INT_MAX bytes.
19154 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19156 Make it possible to build with GCC-4.6+ -O2 -flto.
19158 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19160 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19162 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19163 Call minibuffer-inactive-mode.
19165 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19167 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19168 Update dependencies.
19170 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19172 * data.c (init_data): Remove code for UTS, this system is not
19175 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19177 Don't force ./temacs to start in terminal mode.
19179 * frame.c (make_initial_frame): Initialize faces in all cases, not
19180 only when CANNOT_DUMP is defined.
19181 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19183 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19185 * dispnew.c (add_window_display_history): Use const for the string
19186 pointer. Remove declaration, not needed.
19188 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19190 Use 'inline', not 'INLINE'.
19191 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19192 * alloc.c, fontset.c (INLINE): Remove.
19193 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19194 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19195 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19196 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19197 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19199 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19201 Make it possible to run ./temacs.
19203 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19204 syms_of_callproc does the same thing. Remove test for
19205 "initialized", do it in the caller.
19206 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19208 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19210 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19211 (read_minibuf): Use get_minibuffer.
19212 (syms_of_minibuf): Use DEFSYM.
19213 (Qmetadata): New var.
19214 * data.c (Qbuffer): Don't make it static.
19215 (syms_of_data): Use DEFSYM.
19217 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19219 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19220 (CCL_CODE_MIN): New macro.
19222 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19224 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19226 * eval.c (Qdebug): Now static.
19227 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19228 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19229 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19231 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19233 * image.c: Various fixes to ImageMagick code comments.
19234 (Fimagemagick_types): Doc fix.
19236 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19238 Minor fixes prompted by GCC 4.6.0 warnings.
19240 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19242 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19243 (x_clipboard_manager_save_all): Move extern decl to ...
19244 * xterm.h: ... here, so that it can be checked for consistency.
19246 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19248 * xselect.c (x_clipboard_manager_save_frame)
19249 (x_clipboard_manager_save_all): New functions.
19250 (Fx_clipboard_manager_save): Lisp function deleted.
19252 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19253 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19255 * xterm.h: Update prototype.
19257 2011-05-28 William Xu <william.xwl@gmail.com>
19259 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19260 exiting (Bug#8239).
19262 2011-05-28 Jim Meyering <meyering@redhat.com>
19264 Avoid a sign-extension bug in crypto_hash_function.
19265 * fns.c (to_uchar): Define.
19266 (crypto_hash_function): Use it to convert some newly-signed
19267 variables to unsigned, to avoid sign-extension bugs. For example,
19268 without this change, (md5 "truc") would evaluate to
19269 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19270 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19271 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19273 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19275 Integer overflow fixes.
19277 * dbusbind.c: Serial number integer overflow fixes.
19278 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19279 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19280 to hold a serial number that is too large for a fixnum.
19281 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19282 Check for serial numbers out of range. Decode any serial number
19283 that was so large that it became a float. (Bug#8722)
19285 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19286 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19287 Use XFASTINT rather than XUINT when numbers are nonnegative.
19288 (xd_append_arg, Fdbus_method_return_internal):
19289 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19290 arguments, check that Lisp number is nonnegative, rather than
19291 silently wrapping negative numbers around. (Bug#8722)
19292 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19295 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19297 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19299 ccl: Add integer overflow checks.
19300 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19301 (IN_INT_RANGE): New macros.
19302 (ccl_driver): Use them to check for integer overflow when
19303 decoding a CCL program. Many of the new checks are whether XINT (x)
19304 fits in int; it doesn't always, on 64-bit hosts. The new version
19305 doesn't catch all possible integer overflows, but it's an
19306 improvement. (Bug#8719)
19308 * alloc.c (make_event_array): Use XINT, not XUINT.
19309 There's no need for unsigned here.
19311 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19312 This follows up to the 2011-05-06 change that substituted uintptr_t
19313 for EMACS_INT. This case wasn't caught back then.
19315 Rework Fformat to avoid integer overflow issues.
19316 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19317 now (part of C89). Include <verify.h>.
19318 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19319 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19320 (Fformat): Avoid the prepass trying to compute sizes; it was only
19321 approximate and thus did not catch overflow reliably. Instead, walk
19322 through the format just once, formatting and computing sizes as we go,
19323 checking for integer overflow at every step, and allocating a larger
19324 buffer as needed. Keep track separately whether the format is
19325 multibyte. Keep only the most-recently calculated precision, rather
19326 than them all. Record whether each argument has been converted to
19327 string. Use EMACS_INT, not int, for byte and char and arg counts.
19328 Support field widths and precisions larger than INT_MAX. Avoid
19329 sprintf's undefined behavior with conversion specifications such as %#d
19330 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19331 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19332 formatting out-of-range floating point numbers with int
19333 formats. (Bug#8668)
19335 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19337 * data.c: Avoid integer truncation in expressions involving floats.
19338 * data.c: Include <intprops.h>.
19339 (arith_driver): When there's an integer overflow in an expression
19340 involving floating point, convert the integers to floating point
19341 so that the resulting value does not suffer from catastrophic
19342 integer truncation. For example, on a 64-bit host (* 4
19343 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19344 Do not rely on undefined behavior after integer overflow.
19346 merge count_size_as_multibyte, parse_str_to_multibyte
19347 * character.c, character.h (count_size_as_multibyte):
19348 Rename from parse_str_to_multibyte; all uses changed.
19349 Check for integer overflow.
19350 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19351 since it's now a duplicate of the other. This is more of
19352 a character than a buffer op, so better that it's in character.c.
19353 * fns.c, print.c: Adjust to above changes.
19355 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19357 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19359 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19361 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19362 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19363 (x_clipboard_manager_save): Now static.
19364 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19366 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19367 (crypto_hash_function): Now static.
19368 Fix pointer signedness problems. Avoid unnecessary initializations.
19370 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19372 * termhooks.h (Vselection_alist): Make it terminal-local.
19374 * terminal.c (create_terminal): Initialize it.
19376 * xselect.c: Support for clipboard managers.
19377 (Vselection_alist): Move to termhooks.h as terminal-local var.
19378 (LOCAL_SELECTION): New macro.
19379 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19380 (symbol_to_x_atom): Remove gratuitous arg.
19381 (x_handle_selection_request, lisp_data_to_selection_data)
19382 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19383 (x_own_selection, x_get_local_selection, x_convert_selection):
19384 New arg, specifying work frame. Use terminal-local Vselection_alist.
19385 (some_frame_on_display): Delete unused function.
19386 (Fx_own_selection_internal, Fx_get_selection_internal)
19387 (Fx_disown_selection_internal, Fx_selection_owner_p)
19388 (Fx_selection_exists_p): New optional frame arg.
19389 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19390 (x_handle_selection_clear): Don't treat other terminals with the
19391 same keyboard specially. Use the terminal-local Vselection_alist.
19392 (x_clear_frame_selections): Use Frun_hook_with_args.
19394 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19396 * xterm.h: Add support for those atoms.
19398 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19400 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19401 (converted_selections, conversion_fail_tag): New global variables.
19402 (x_selection_request_lisp_error): Free the above.
19403 (x_get_local_selection): Remove unnecessary code.
19404 (x_reply_selection_request): Args changed; handle arbitrary array
19405 of converted selections stored in converted_selections.
19406 Separate the XChangeProperty and SelectionNotify steps.
19407 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19408 (x_convert_selection): New function.
19409 (x_handle_selection_event): Simplify.
19410 (x_get_foreign_selection): Don't ignore incoming requests while
19411 waiting for an answer; this will fail when we implement
19412 SAVE_TARGETS, and seems unnecessary anyway.
19413 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19414 (Vx_sent_selection_functions): Doc fix.
19416 2011-05-26 Leo Liu <sdl.web@gmail.com>
19418 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19420 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19422 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19424 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19425 for fringe update if it has periodic bitmap.
19426 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19427 and fringe_bitmap_periodic_p.
19429 * fringe.c (get_fringe_bitmap_data): New function.
19430 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19431 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19432 row. Mark glyph row for fringe update if periodicity changed.
19434 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19435 for fringe update unless it has periodic bitmap.
19437 2011-05-25 Kenichi Handa <handa@m17n.org>

19456 Remove macros that are defined and never used.
19457 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19459 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19461 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19462 (Fx_get_selection_internal): Minor cleanup.

19488 report_file_error introduced by the change from 2011-05-07.
19490 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19492 * systime.h (Time): Define only if emacs is defined.
19493 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19494 where the include path doesn't have X11/X.h by default. See
19495 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19497 2011-05-20 Kenichi Handa <handa@m17n.org>
19499 * composite.c (find_automatic_composition): Fix previous change.
19501 2011-05-20 Glenn Morris <rgm@gnu.org>

19512 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19513 (lisp): Set the order to that of loadup.el.
19514 (shortlisp): Make it a copy of $lisp.
19515 (SOME_MACHINE_LISP): Remove.
19516 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19517 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19519 2011-05-18 Kenichi Handa <handa@m17n.org>
19521 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19522 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19523 (find_automatic_composition): Mostly rewrite for efficiency.
19525 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19527 * makefile.w32-in: Update dependencies.
19529 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19531 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19532 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19534 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19536 Fix some integer overflow issues, such as string length overflow.
19538 * insdel.c (count_size_as_multibyte): Check for string overflow.
19540 * character.c (lisp_string_width): Check for string overflow.
19541 Use EMACS_INT, not int, for string indexes and lengths; in
19542 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19543 the resulting string length overflows an EMACS_INT; instead,
19544 report a string overflow if no precision given. When checking for
19545 precision exhaustion, use a check that cannot possibly have
19546 integer overflow. (Bug#8675)
19547 * character.h (lisp_string_width): Adjust to new signature.
19549 * alloc.c (string_overflow): New function.
19550 (Fmake_string): Use it. This doesn't change behavior, but saves
19551 a few bytes and will simplify future changes.
19552 * character.c (string_escape_byte8): Likewise.
19553 * lisp.h (string_overflow): New decl.
19555 Fixups, following up to the user-interface timestamp change.
19556 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19557 for UI timestamps, instead of unsigned long.
19558 * msdos.c (mouse_get_pos): Likewise.
19559 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19560 * w32gui.h (Time): Define by including "systime.h" rather than by
19561 declaring it ourselves. (Bug#8664)
19563 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19564 * image.c (clear_image_cache): Likewise.
19566 * term.c (term_mouse_position): Don't assume time_t wraparound.
19568 Be more systematic about user-interface timestamps.
19569 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19570 and sometimes 'EMACS_UINT', to represent these timestamps.
19571 This change causes it to use 'Time' uniformly, as that's what X uses.
19572 This makes the code easier to follow, and makes it easier to catch
19573 integer overflow bugs such as Bug#8664.
19574 * frame.c (Fmouse_position, Fmouse_pixel_position):
19575 Use Time, not unsigned long, for user-interface timestamps.
19576 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19577 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19578 * keyboard.h (last_event_timestamp): Likewise.
19579 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19580 * menu.h (xmenu_show): Likewise.
19581 * term.c (term_mouse_position): Likewise.
19582 * termhooks.h (struct input_event.timestamp): Likewise.
19583 (struct terminal.mouse_position_hook): Likewise.
19584 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19585 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19586 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19587 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19588 what it was before.
19589 * menu.h, termhooks.h: Include "systime.h", for Time.
19591 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19592 Don't assume that the difference between two unsigned long values
19593 can fit into an integer. At this point, we know button_down_time
19594 <= event->timestamp, so the difference must be nonnegative, so
19595 there's no need to cast the result if double-click-time is
19596 nonnegative, as it should be; check that it's nonnegative, just in
19597 case. This bug is triggered when events are more than 2**31 ms
19598 apart (about 25 days). (Bug#8664)
19600 * xselect.c (last_event_timestamp): Remove duplicate decl.
19601 (x_own_selection): Remove needless cast to unsigned long.
19603 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19604 that always fit in int. Use a sentinel instead of a counter, to
19605 avoid a temp and to allay GCC's concerns about possible int overflow.
19606 * frame.h (struct frame): Use int for menu_bar_items_used
19607 instead of EMACS_INT, since it always fits in int.
19609 * menu.c (grow_menu_items): Check for int overflow.
19611 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19613 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19614 Before, the code was not consistent. These values cannot exceed
19615 2**31 - 1 so there's no need to make them unsigned.
19616 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19617 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19618 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19620 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19622 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19623 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19624 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19625 presumably because the widths might not match.
19627 * window.c (size_window): Avoid needless test at loop start.
19629 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19631 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19633 2011-05-12 Drew Adams <drew.adams@oracle.com>
19635 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19637 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19639 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19640 `width' to `bar_area_x' and `bar_area_width', respectively.
19641 (x_scroll_run): Take account of fringe background extension.
19643 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19644 Rename local vars `left' and `width' to `bar_area_x' and
19645 `bar_area_width', respectively.
19646 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19647 background extension.
19649 2011-05-10 Jim Meyering <meyering@redhat.com>
19651 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19653 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19655 * image.c (Finit_image_library): Return t for built-in image types,
19656 like pbm and xbm. (Bug#8640)
19658 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19660 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19662 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19664 * w32console.c (Fset_screen_color): Doc fix.
19665 (Fget_screen_color): New function.
19666 (syms_of_ntterm): Defsubr it.
19668 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19669 unlink the temporary file if Fcall_process didn't create it in the
19671 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19672 child process will be redirected to a file specified with `:file'.
19673 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19674 cue to call_process_cleanup not to close that handle.
19676 2011-05-07 Ben Key <bkey76@gmail.com>
19678 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19679 one of two shell specific rules, either bootstrap-temacs-CMD or
19680 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19681 to the previous implementation of the bootstrap-temacs rule.
19682 The bootstrap-temacs-CMD rule is similar to the previous
19683 implementation of the bootstrap-temacs rule except that it
19684 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19687 These changes, along with some changes to nt/configure.bat,
19688 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19689 earlier fix to add support for --cflags and --ldflags options
19690 that include quotes so that it works whether make uses cmd or
19693 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19695 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19696 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19698 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19699 a string. Handle both cases.
19700 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19701 (Fdbus_register_method): Use Qinvalid_function.
19703 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19705 * makefile.w32-in: Update dependencies.
19706 (LISP_H): Add inttypes.h and stdin.h.
19707 (PROCESS_H): Add unistd.h.
19709 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19711 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19712 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19714 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19716 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19718 * term.c (vfatal): Remove stray call to va_end.
19719 It's not needed and the C Standard doesn't allow it here anyway.
19721 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19722 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19724 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19727 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19729 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19731 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19733 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19735 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19737 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19738 * charset.c (Fdefine_charset_internal): Don't initialize
19739 charset.code_space[15]. The value was garbage, on hosts with
19740 32-bit int (Bug#8600).
19742 * lread.c (read_integer): Be more consistent with string-to-number.
19743 Use string_to_number to do the actual conversion; this avoids
19744 rounding errors and fixes some other screwups. Without this fix,
19745 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19746 (digit_to_number): Move earlier, for benefit of read_integer.
19747 Return -1 if the digit is out of range for the base, -2 if it is
19748 not a digit in any supported base. (Bug#8602)
19750 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19752 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19753 to match comment at start of function. This also removes a
19754 GCC warning about overflow in a 32+64-bit port.
19756 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19758 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19759 Reported by Stefan Monnier in
19760 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19761 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19762 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19764 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19765 (EMACS_UINTPTR): Likewise, with uintptr_t.
19767 * lisp.h: Prefer 64-bit EMACS_INT if available.
19768 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19769 on 32-bit hosts that have 64-bit int, so that they can access
19771 However, temporarily disable this change unless the temporary
19772 symbol WIDE_EMACS_INT is defined.
19774 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19776 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19777 This removes an assumption that EMACS_INT and long are the same
19778 width as pointers. The assumption is true for Emacs porting targets
19779 now, but we want to make other targets possible.
19780 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19781 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19782 In the rest of the code, change types of integers that hold casted
19783 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19784 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19785 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19786 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19787 No need to cast type when ORing.
19788 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19789 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19790 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19791 assume EMACS_INT is the same width as char *.
19792 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19793 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19794 Remove no-longer-needed casts.
19795 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19796 (xg_tool_bar_help_callback, xg_make_tool_item):
19797 Use EMACS_INTPTR to hold an integer
19798 that will be cast to void *; this can avoid a GCC warning
19799 if EMACS_INT is not the same width as void *.
19800 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19801 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19802 (current_message_1, set_message_1):
19803 Use a local to convert to proper width without a cast.
19804 * xmenu.c (dialog_selection_callback): Likewise.
19806 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19807 Also, don't assume VALBITS / RAND_BITS is less than 5,
19808 and don't rely on undefined behavior when shifting a 1 left into
19810 * lisp.h (get_random): Change signature to match.
19812 * lread.c (hash_string): Use size_t, not int, for hash computation.
19813 Normally we prefer signed values; but hashing is special, because
19814 it's better to use unsigned division on hash table sizes so that
19815 the remainder is nonnegative. Also, size_t is the natural width
19816 for hashing into memory. The previous code used 'int', which doesn't
19817 retain enough info to hash well into very large tables.
19818 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19820 * dbusbind.c: Don't possibly lose pointer info when converting.
19821 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19822 Use XPNTR rather than XHASH, so that the high-order bits of
19823 the pointer aren't lost when converting through void *.
19825 * eval.c (Fautoload): Don't double-shift a pointer.
19827 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19829 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19831 * gnutls.c (DEF_GNUTLS_FN):
19832 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19834 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19836 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19839 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19841 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19842 New version that can reserve upto 2GB of heap space.
19844 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19846 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19848 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19850 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19851 `gnutls_certificate_set_x509_key_file'.
19853 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19855 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19856 Update dependencies.
19858 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19860 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19861 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19862 Remove unused parameter `fildes'.
19863 * process.c (read_process_output, send_process): Don't pass it.
19865 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19867 Fix previous change: the library cache is defined in w32.c.
19868 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19869 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19871 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19873 Implement dynamic loading of GnuTLS on Windows.
19875 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19876 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19877 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19880 * gnutls.c (Qgnutls_dll): Define.
19881 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19882 (gnutls_*): Declare function pointers.
19883 (init_gnutls_functions): New function to initialize function pointers.
19884 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19885 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19886 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19887 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19888 (emacs_gnutls_write, emacs_gnutls_read)
19889 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19890 (Fgnutls_available_p): New function.
19891 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19892 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19893 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19895 * image.c: Include w32.h.
19896 (Vimage_type_cache): Delete.
19897 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19898 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19899 (w32_delayed_load): Move to w32.c.
19901 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19903 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19904 (w32_delayed_load): Move from image.c. When loading a library, record
19905 its filename in the :loaded-from property of the library id.
19906 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19907 Initialize and staticpro them.
19908 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19910 * process.c: Include lisp.h before w32.h, not after.
19911 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19912 instead of gnutls_record_check_pending.
19914 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19916 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19918 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19919 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19922 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19924 * xterm.c (x_set_frame_alpha): Do not set property on anything
19925 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19927 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19929 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19931 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19933 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19934 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19940 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19941 (Qgnutls_bootprop_callbacks_verify): Make static.
19943 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>

19953 * sysdep.c (interruptible_wait_for_termination): New function
19954 which is like wait_for_termination, but allows keyboard
19957 * callproc.c (Fcall_process): Add (:file "file") as an option for
19959 (Fcall_process_region): Ditto.
19961 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19963 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19964 rather than `XVECTOR (FOO)->size'.
19966 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19967 inttypes.h, as a gnulib replacement is used if it not available in
19970 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19972 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19973 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19974 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19976 * coding.c (coding_alloc_by_realloc): Error out if destination
19977 will grow beyond MOST_POSITIVE_FIXNUM.
19978 (decode_coding_emacs_mule): Abort if there isn't enough place in
19979 charbuf for the composition carryover bytes. Reserve an extra
19980 space for up to 2 characters produced in a loop.
19981 (decode_coding_iso_2022): Abort if there isn't enough place in
19982 charbuf for the composition carryover bytes.
19984 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19986 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19987 aborting when %lld or %lll format is passed.
19988 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19989 %llo or %llx format is passed. (Bug#8545)
19991 * window.c (window_scroll_line_based): Use a marker instead of
19992 simple variables to record original value of point. (Bug#7952)
19994 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19995 produced by %s or %c overflows available buffer space. (Bug#8545)
19997 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19999 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20000 (SIZE_MAX): Move defn after all includes, as they might #define it.
20002 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20004 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20006 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20008 * keyboard.c (Qdelayed_warnings_hook): Define.
20009 (command_loop_1): Run `delayed-warnings-hook'
20010 if Vdelayed_warnings_list is non-nil.
20011 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20012 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20014 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20016 * doprnt.c (doprnt): Don't return value smaller than the buffer
20017 size if the message was truncated. (Bug#8545).
20019 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20021 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20022 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20024 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20026 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20028 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20030 * makefile.w32-in: Update dependencies.
20032 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20034 Improve `doprnt' and its usage. (Bug#8545)
20035 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20036 `format_end'. Remove support for %l as a conversion specifier.
20037 Don't use xrealloc. Improve diagnostics when the %l size modifier
20038 is used. Update the commentary.
20040 * eval.c (verror): Simplify calculation of size_t.
20042 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20045 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20047 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20050 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20052 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20053 This makes this file independent of the recent pseudovector change.
20055 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20057 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20059 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20060 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20061 Remove unused local.
20062 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20064 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20065 GCC 4.6.0 optimizes based on type-based alias analysis.
20066 For example, if b is of type struct buffer * and v of type struct
20067 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20068 != &v->size, and therefore "v->size = 1; b->size = 2; return
20069 v->size;" must therefore return 1. This assumption is incorrect
20070 for Emacs, since it type-puns struct Lisp_Vector * with many other
20071 types. To fix this problem, this patch adds a new type struct
20072 vectorlike_header that documents the constraints on layout of vectors
20073 and pseudovectors, and helps optimizing compilers not get fooled
20074 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20075 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20076 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20078 (XSETPVECTYPE): Rewrite in terms of new macro.
20079 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20080 This is a bit clearer, and further avoids the possibility of
20081 undesirable aliasing.
20082 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20083 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20084 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20085 since Lisp_Subr is a special case (no "next" field).
20086 (ASIZE): Now uses header.size rather than size.
20087 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20088 to avoid the hassle of writing XVECTOR (foo)->header.size.
20089 (struct vectorlike_header): New type.
20090 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20091 object, to help avoid aliasing.
20092 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20093 (SUBRP): Likewise, since Lisp_Subr is a special case.
20094 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20095 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20096 (struct Lisp_Hash_Table): Combine first two members into a single
20097 struct vectorlike_header member. All uses of "size" and "next" members
20098 changed to be "header.size" and "header.next".
20099 * buffer.h (struct buffer): Likewise.
20100 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20101 * frame.h (struct frame): Likewise.
20102 * process.h (struct Lisp_Process): Likewise.
20103 * termhooks.h (struct terminal): Likewise.
20104 * window.c (struct save_window_data, struct saved_window): Likewise.
20105 * window.h (struct window): Likewise.
20106 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20107 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20108 * buffer.c (init_buffer_once): Likewise.
20109 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20111 * process.c (Fformat_network_address): Use local var for size,
20114 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20116 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20117 * data.c (atof): Remove decl; no longer used or needed.
20118 (digit_to_number): Move to lread.c.
20119 (Fstring_to_number): Use new string_to_number function, to be
20120 consistent with how the Lisp reader treats infinities and NaNs.
20121 Do not assume that floating-point numbers represent EMACS_INT
20122 without losing information; this is not true on most 64-bit hosts.
20123 Avoid double-rounding errors, by insisting on integers when
20124 parsing non-base-10 numbers, as the documentation specifies.
20125 * lisp.h (string_to_number): New decl, replacing ...
20126 (isfloat_string): Remove.
20127 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20128 (read1): Do not accept +. and -. as integers; this
20129 appears to have been a coding error. Similarly, do not accept
20130 strings like +-1e0 as floating point numbers. Do not report
20131 overflow for integer overflows unless the base is not 10 which
20132 means we have no simple and reliable way to continue.
20133 Break out the floating-point parsing into a new
20134 function string_to_number, so that Fstring_to_number parses
20135 floating point numbers consistently with the Lisp reader.
20136 (digit_to_number): Move here from data.c. Make it static inline.
20137 (E_CHAR, EXP_INT): Remove, replacing with ...
20138 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20139 (string_to_number): New function, replacing isfloat_string.
20140 This function checks for valid syntax and produces the resulting
20141 Lisp float number too. Rework it so that string-to-number
20142 no longer mishandles examples like "1.0e+". Use strtoumax,
20143 so that overflow for non-base-10 numbers is reported only when
20144 there's no portable and simple way to convert to floating point.
20146 * textprop.c (set_text_properties_1): Rewrite for clarity,
20147 and to avoid GCC warning about integer overflow.
20149 * intervals.h (struct interval): Use EMACS_INT for members
20150 where EMACS_UINT might cause problems. See
20151 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20152 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20153 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20155 (offset_intervals): Tell GCC not to worry about length overflow
20156 when negating a negative length.
20158 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20159 (overrun_check_free): Likewise.
20161 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20162 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20165 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20166 (gnutls_make_error): Rename local to avoid shadowing.
20167 (gnutls_emacs_global_deinit): ifdef out; not used.
20168 (Fgnutls_boot): Use const for pointer to readonly storage.
20169 Comment out unused local. Fix pointer signedness problems.
20171 * lread.c (openp): Don't stuff size_t into an 'int'.
20172 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20173 about possible signed overflow.
20175 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20176 (GDK_KEY_g): Don't define if already defined.
20177 (xg_prepare_tooltip): Avoid pointer signedness problem.
20178 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20180 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20181 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20183 * xfns.c (Fx_window_property): Simplify a bit,
20184 to make a bit faster and to avoid GCC 4.6.0 warning.
20185 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20187 * fns.c (internal_equal): Don't assume size_t fits in int.
20189 * alloc.c (compact_small_strings): Tighten assertion a little.
20191 Replace pEd with more-general pI, and fix some printf arg casts.
20192 * lisp.h (pI): New macro, generalizing old pEd macro to other
20193 conversion specifiers. For example, use "...%"pI"d..." rather
20194 than "...%"pEd"...".
20195 (pEd): Remove. All uses replaced with similar uses of pI.
20196 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20197 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20198 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20199 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20200 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20201 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20202 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20204 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20205 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20206 * print.c (safe_debug_print, print_object): Likewise.
20207 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20209 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20210 avoiding the 0 flag, which is not portable.
20211 * process.c (Fmake_network_process): Use pI to avoid cast.
20212 * region-cache.c (pp_cache): Likewise.
20213 * xdisp.c (decode_mode_spec): Likewise.
20214 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20215 behavior on 64-bit hosts with printf arg.
20216 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20217 (x_stop_queuing_selection_requests): Likewise.
20218 (x_get_window_property): Don't truncate byte count to an 'int'
20221 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20222 here, since it parses constructs like leading '-' and spaces,
20223 which are not wanted; and it overflows with large numbers.
20224 Instead, simply match F[0-9]+, which is what is wanted anyway.
20226 * alloc.c: Remove unportable assumptions about struct layout.
20227 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20228 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20229 (allocate_vectorlike, make_pure_vector): Use the new macros,
20230 plus offsetof, to remove unportable assumptions about struct layout.
20231 These assumptions hold on all porting targets that I know of, but
20232 they are not guaranteed, they're easy to remove, and removing them
20233 makes further changes easier.
20235 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20236 This doesn't fix a bug but makes the code clearer.
20237 (string_overrun_cookie): Now const. Use initializers that
20238 don't formally overflow signed char, to avoid warnings.
20239 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20240 can cause Emacs to crash when string overrun checking is enabled.
20241 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20242 multiple of sizeof (EMACS_INT); it need not be, if
20243 alignof(EMACS_INT) < sizeof (EMACS_INT).
20244 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20246 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20248 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20250 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20252 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20253 supposed to be handshaking. (Bug#8556)
20254 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20256 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
20258 * lisp.h (Qdebug): List symbol.
20259 * eval.c (Qdebug): Restore global linkage.

20261 (handle_user_signal): Break into debugger when debug-on-event
20262 matches the current signal symbol.
20264 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20266 * alloc.c (check_sblock, check_string_bytes)
20267 (check_string_free_list): Convert to standard C.
20269 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20271 * w32.c (emacs_gnutls_push): Fix typo.
20273 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20275 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20276 "cast to pointer from integer of different size".
20278 Improve doprnt and its use in verror. (Bug#8545)
20279 * doprnt.c (doprnt): Document the set of format control sequences
20280 supported by the function. Use SAFE_ALLOCA instead of always
20283 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20284 is one byte too soon. Don't use xrealloc; instead xfree and
20287 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20289 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20292 * gnutls.c: Renamed global_initialized to
20293 gnutls_global_initialized. Added internals for the
20294 :verify-hostname-error, :verify-error, and :verify-flags
20295 parameters of `gnutls-boot' and documented those parameters in the
20296 docstring. Start callback support.
20297 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20298 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20299 on error. Return error code.
20300 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20301 (emacs_gnutls_read): Likewise.
20302 (Fgnutls_boot): Return handshake error code.
20303 (emacs_gnutls_handle_error): New function.
20304 (wsaerror_to_errno): Likewise.

20309 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
20310 (emacs_gnutls_push): Likewise.
20312 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
20314 * process.c (wait_reading_process_output): Check if GnuTLS
20315 buffered some data internally if no FDs are set for TLS
20318 * makefile.w32-in (OBJ2): Add gnutls.$(O).

20325 display_replaced_before_p argument into display_replaced_p, to
20326 make it consistent with the commentary. Fix typos in the

20341 to changes in oldXMenu/XMenu.h from 2011-04-16.
20342 (struct XMenu): Declare `help_text' `const char **'.

20353 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
20355 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
20358 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
20359 changes in globals.h immediately force recompilation.
20360 (TAGS): Depend on $(CURDIR)/m/intel386.h and
20361 $(CURDIR)/s/ms-w32.h.
20362 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

20365 (syms_of_character): Don't defsubr it.
20366 <char-direction-table>: Deleted.
20368 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20370 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
20371 * doprnt.c: Include limits.h.
20372 (SIZE_MAX): New macro.
20373 (doprnt): Return a size_t value. 2nd arg is now size_t.
20374 Many local variables are now size_t instead of int or unsigned.
20375 Improve overflow protection. Support `l' modifier for integer
20376 conversions. Support %l conversion. Don't assume an EMACS_INT
20377 argument for integer conversions and for %c.
20379 * lisp.h (doprnt): Restore prototype.
20381 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
20382 $(SRC)/character.h.
20384 * Makefile.in (base_obj): Add back doprnt.o.
20386 * deps.mk (doprnt.o): Add back prerequisites.
20387 (callint.o): Depend on character.h.

20627 * process.c (send_process): Adjust to the new signatures of
20628 emacs_write and emacs_gnutls_write. Do not attempt to store

20854 worth the hassle of breaking this out.
20856 * xterm.c: Make symbols static if they're not exported.
20857 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

20958 * lisp.h: Remove these decls.
20960 * buffer.c (buffer_count): Remove unused var.
20962 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

20969 * atimer.h (run_all_atimers): Remove; not exported.
20971 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20972 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20973 was inaccessible from Lisp.
20974 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20975 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20977 alloc.c: Import and export fewer symbols, and remove unused items.
20978 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20980 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20981 it's not optimized away by whole-program optimization.

20994 (mark_backtrace): Define only if BYTE_MARK_STACK.
20995 * xdisp.c (message_enable_multibyte): Now static.
20997 Declare Lisp_Object Q* variables to be 'static' if not exported.
20998 This makes it easier for human readers (and static analyzers)
20999 to see whether these variables are used from other modules.
21000 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21001 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

21010 Remove decls of unexported vars.
21011 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21013 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21015 Make Emacs functions such as Fatom 'static' by default.
21016 This makes it easier for human readers (and static analyzers)
21017 to see whether these functions can be called from other modules.
21018 DEFUN now defines a static function. To make the function external
21019 so that it can be used in other C modules, use the new macro DEFUE.
21020 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21021 (Finit_image_library):
21022 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21023 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21024 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21025 Remove decls, since these functions are now static.
21026 (Funintern, Fget_internal_run_time): New decls, since these functions
21027 were already external.
21029 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21030 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21036 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21037 Mark functions with DEFUE instead of DEFUN,
21038 if they are used in other modules.
21039 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21040 decls for now-static functions.
21041 * buffer.h (Fdelete_overlay): Remove decl.
21042 * callproc.c (Fgetenv_internal): Mark as internal.
21043 * composite.c (Fremove_list_of_text_properties): Remove decl.

21050 * fileio.c (Fmake_symbolic_link): New forward static decl.
21051 * image.c (Finit_image_library): New forward static decl.
21052 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21053 * intervals.h (Fprevious_property_change):
21054 (Fremove_list_of_text_properties): Remove decls.
21055 * keyboard.c (Fthis_command_keys): Remove decl.
21056 (Fcommand_execute): New forward static decl.

21072 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21074 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21077 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21079 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21080 when at ZV. (Bug#8487)
21082 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21084 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21088 * termcap.c (tgetent): Likewise.
21089 * xfns.c (x_default_font_parameter): Likewise.
21090 * xsettings.c (read_and_apply_settings): Likewise.
21092 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21093 (overrun_check_free): Protoize.
21095 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21097 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21098 since callers should never pass a negative size.
21099 Change the signature to match that of plain 'read' and 'write'; see
21100 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21101 * lisp.h: Update prototypes of emacs_write and emacs_read.
21103 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21105 * xdisp.c (redisplay_window): Don't try to determine the character
21106 position of the scroll margin if the window start point w->startp
21107 is outside the buffer's accessible region. (Bug#8468)
21109 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21111 Fix write-region and its subroutines for buffers > 2GB.
21112 * fileio.c (a_write, e_write): Modify declaration of arguments and
21113 local variables to support buffers larger than 2GB.
21114 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21116 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21117 argument, local variables, and return value.
21119 * lisp.h: Update prototypes of emacs_write and emacs_read.
21121 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21123 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21125 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21127 Fix more problems found by GCC 4.6.0's static checks.
21129 * xdisp.c (vmessage): Use a better test for character truncation.
21131 * charset.c (load_charset_map): <, not <=, for optimization,
21132 and to avoid potential problems with integer overflow.
21133 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21134 * casetab.c (set_identity, shuffle): Likewise.
21135 * editfns.c (Fformat): Likewise.
21136 * syntax.c (skip_chars): Likewise.
21138 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21139 This also lets GCC 4.6.0 generate slightly better loop code.
21141 * callint.c (Fcall_interactively): <, not <=, for optimization.
21142 (Fcall_interactively): Count the number of arguments produced,
21143 not the number of arguments given. This is simpler and lets GCC
21144 4.6.0 generate slightly better code.
21146 * ftfont.c: Distingish more carefully between FcChar8 and char.
21147 The previous code passed unsigned char * to a functions like
21148 strlen and xstrcasecmp that expect char *, which does not
21149 conform to the C standard.
21150 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21151 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21152 char * when the C standard requires it.
21154 * keyboard.c (read_char): Remove unused var.
21156 * eval.c: Port to Windows vsnprintf (Bug#8435).
21157 Include <limits.h>.
21158 (SIZE_MAX): Define if the headers do not.
21159 (verror): Do not give up if vsnprintf returns a negative count.
21160 Instead, grow the buffer. This ports to Windows vsnprintf, which
21161 does not conform to C99. Problem reported by Eli Zaretskii.
21162 Also, simplify the allocation scheme, by avoiding the need for
21163 calling realloc, and removing the ALLOCATED variable.
21165 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21167 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21168 But keep the doprint source code for now, as we might revamp it
21169 and use it again (Bug#8435).
21170 * lisp.h (doprnt): Remove.
21171 * Makefile.in (base_obj): Remove doprnt.o.
21172 * deps.mk (doprnt.o): Remove.
21174 error: Print 32- and 64-bit integers portably (Bug#8435).
21175 Without this change, on typical 64-bit hosts error ("...%d...", N)
21176 was used to print both 32- and 64-bit integers N, which relied on
21177 undefined behavior.
21178 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21179 * lisp.h (error, verror): Mark as printf-like functions.
21180 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21181 Report overflow in size calculations when allocating printf buffer.
21182 Do not truncate output string at its first null byte.
21183 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21184 Truncate the output at a character boundary, since vsnprintf does not
21186 * charset.c (check_iso_charset_parameter): Convert internal
21187 character to string before calling 'error', since %c now has the
21189 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21190 overflow when computing char to be passed to 'error'. Do not
21191 pass Lisp_Object to 'error'; pass the integer instead.
21192 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21193 formatted with plain %d.
21195 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21197 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21199 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21201 * xterm.c (x_catch_errors): Remove duplicate declaration.
21203 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21205 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21207 2011-04-10 Jim Meyering <meyering@redhat.com>
21209 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21210 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21211 return ssize_t not "int", and use size_t as the buffer length.
21212 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21213 * gnutls.h: Update declarations.
21214 * process.c (read_process_output): Use ssize_t, to match.
21215 (send_process): Likewise.
21217 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21219 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21221 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21223 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21224 Use unsigned char, to match FcChar8 type definition.
21226 * xterm.c (handle_one_xevent):
21227 * xmenu.c (create_and_show_popup_menu):
21228 * xselect.c (x_decline_selection_request)
21229 (x_reply_selection_request): Avoid type-punned deref of X events.
21231 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21233 Fix some uses of `int' instead of EMACS_INT.
21234 * search.c (string_match_1, fast_string_match)
21235 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21236 (scan_buffer, find_next_newline_no_quit)
21237 (find_before_next_newline, search_command, Freplace_match)
21238 (Fmatch_data): Make some `int' variables be EMACS_INT.
21240 * xdisp.c (display_count_lines): 3rd argument and return value now
21241 EMACS_INT. All callers changed.
21242 (pint2hrstr): Last argument is now EMACS_INT.
21244 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21245 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

21287 instead of using internal_with_output_to_temp_buffer.
21288 (Qhelp_form_show): New var.
21289 (syms_of_keyboard): Use DEFSYM macro.
21291 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21304 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21306 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21308 Fix more problems found by GCC 4.6.0's static checks.

21314 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21316 * xdisp.c (vmessage): Mark as a printf-like function.
21318 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

21325 to system-supplied API.
21327 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21329 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21330 This avoids several warnings with gcc -Wstrict-overflow.
21331 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21332 directly, rather than having caller test rule sign. This avoids
21333 some unnecessary tests.
21334 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21335 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21336 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21338 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21339 (xfont_open): Avoid unnecessary tests.
21341 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21343 * composite.h, composite.c (composition_gstring_put_cache):
21344 Use EMACS_INT, not int, for length.
21346 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21347 breaking out part of COMPOSITION_DECODE_RULE.
21348 (COMPOSITION_DECODE_RULE): Use it.
21349 * composite.c (get_composition_id): Remove unused local vars,
21350 by using the new macro.
21352 * textprop.c (set_text_properties_1): Change while to do-while,
21353 since the condition is always true at first.
21355 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21356 (interval_deletion_adjustment): Return unsigned value.
21359 * process.c (list_processes_1, create_pty, read_process_output):
21360 (exec_sentinel): Remove vars that were set but not used.
21361 (create_pty): Remove unnecessary "volatile"s.
21362 (Fnetwork_interface_info): Avoid possibility of int overflow.
21363 (read_process_output): Do adaptive read buffering even if carryover.
21364 (read_process_output): Simplify nbytes computation if buffered.
21366 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
21368 * syntax.c (scan_words): Remove var that was set but not used.
21369 (update_syntax_table): Use unsigned instead of int.
21371 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

21373 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21375 * print.c (print_error_message): Avoid int overflow.
21377 * font.c (font_list_entities): Redo for clarity,
21378 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21380 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21381 (font_score): Avoid potential overflow in diff calculation.
21383 * fns.c (substring_both): Remove var that is set but not used.
21384 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21386 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21388 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21389 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21390 can always succeed if overflow has undefined behavior.
21392 * search.c (boyer_moore, wordify): Remove vars set but not used.
21393 (wordify): Omit three unnecessary tests.
21395 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21396 All callers changed. This avoids the need for an unused var.
21398 * casefiddle.c (casify_region): Remove var that is set but not used.
21400 * dired.c (file_name_completion): Remove var that is set but not used.
21402 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21404 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21405 (Finsert_file_contents): Remove unnecessary code checking fd.
21407 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21408 Check for integer overflow on size calculations.
21410 * buffer.c (Fprevious_overlay_change): Remove var that is set
21413 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21414 Remove vars that are set but not used.
21415 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21416 (timer_check_2): Mark vars as initialized.
21418 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21420 * image.c (lookup_image): Remove var that is set but not used.
21421 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21423 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21424 that are set but not used.
21426 * xfns.c (make_invisible_cursor): Don't return garbage
21427 if XCreateBitmapFromData fails (Bug#8410).
21429 * xselect.c (x_get_local_selection, x_handle_property_notify):
21430 Remove vars that are set but not used.
21432 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21433 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21435 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21436 Remove var that is set but not used.
21437 (scroll_bar_windows_size): Now size_t, not int.
21438 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21439 Check for overflow.
21441 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21442 (map_tty_color) [!defined MSDOS]: Likewise.
21444 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21446 * coding.c: Remove vars that are set but not used.
21447 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21448 All callers changed.
21449 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21450 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21451 (decode_coding_charset): Remove vars that are set but not used.
21453 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21454 that is set but not used.
21456 * print.c (print_object): Remove var that is set but not used.
21458 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21459 The gnulib version avoids calling malloc in the usual case,
21460 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21461 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21462 * filelock.c (current_lock_owner): Likewise.
21463 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21464 * sysdep.c: Include allocator.h, careadlinkat.h.
21465 (emacs_no_realloc_allocator): New static constant.
21466 (emacs_readlink): New function.
21467 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21468 ../lib/careadlinkat.h.
21470 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21472 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21473 first non-nil return value).
21475 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21477 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21478 if not defined (Bug#8403).
21480 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21482 * xdisp.c (display_count_lines): Remove parameter `start',
21483 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21484 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21485 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21487 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21488 and thereabouts. All callers changed.
21489 (get_per_char_metric): Remove parameter `f', unused since
21490 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21492 2011-04-02 Jim Meyering <meyering@redhat.com>
21494 do not dereference NULL upon failed strdup
21495 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21496 (ns_get_family): Likewise.
21498 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21500 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21502 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21504 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21507 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21509 Add lexical binding.
21511 * window.c (Ftemp_output_buffer_show): New fun.
21512 (Fsave_window_excursion):
21513 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21515 * lread.c (lisp_file_lexically_bound_p): New function.

21520 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21522 (syms_of_lread): Declare `lexical-binding'.
21524 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21526 * keyboard.c (eval_dyn): New fun.
21527 (menu_item_eval_property): Use it.
21529 * image.c (parse_image_spec): Use Ffunctionp.
21531 * fns.c (concat, mapcar1): Accept byte-code-functions.
21533 * eval.c (Fsetq): Handle lexical vars.
21534 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21535 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21536 (FletX, Flet): Obey lexical binding.
21537 (Fcommandp): Handle closures.
21538 (Feval): New `lexical' arg.
21539 (eval_sub): New function extracted from Feval. Use it almost
21540 everywhere where Feval was used. Look up vars in lexical env.
21542 (Ffunctionp): Move from subr.el.
21543 (Ffuncall): Handle closures.
21544 (apply_lambda): Remove `eval_flags'.
21545 (funcall_lambda): Handle closures and new byte-code-functions.
21546 (Fspecial_variable_p): New function.
21547 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21548 but without exporting it to Lisp.
21550 * doc.c (Fdocumentation, store_function_docstring):
21551 * data.c (Finteractive_form): Handle closures.
21553 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21556 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21558 (exec_byte_code): New function extracted from Fbyte_code to handle new
21559 calling convention for byte-code-functions. Add new byte-codes.
21561 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21563 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21565 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21567 * xdisp.c (redisplay_internal): Fix prototype.
21569 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21571 * xdisp.c (SCROLL_LIMIT): New macro.
21572 (try_scrolling): Use it when setting scroll_limit.
21573 Limit scrolling to 100 screen lines.
21574 (redisplay_window): Even when falling back on "recentering",
21575 position point in the window according to scroll-conservatively,
21576 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21578 (try_scrolling): When point is above the window, allow searching
21579 as far as scroll_max, or one screenful, to compute vertical
21580 distance from PT to the scroll margin position. This prevents
21581 try_scrolling from unnecessarily failing when
21582 scroll-conservatively is set to a value slightly larger than the
21583 window height. Clean up the case of PT below the margin at bottom
21584 of window: scroll_max can no longer be INT_MAX. When aggressive
21585 scrolling is in use, don't let point enter the opposite scroll
21586 margin as result of the scroll.
21587 (syms_of_xdisp) <scroll-conservatively>: Document the
21588 threshold of 100 lines for never-recentering scrolling.
21590 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21592 * dispextern.h (move_it_by_lines):
21593 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21594 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21595 (message_log_check_duplicate): Remove parameters `prev_bol' and
21596 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21597 (redisplay_internal): Remove parameter `preserve_echo_area',
21598 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21600 * indent.c (Fvertical_motion):
21601 * window.c (window_scroll_pixel_based, Frecenter):
21602 Don't pass `need_y_p' to `move_it_by_lines'.
21604 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21606 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21607 steal a few bits to be more compact.
21608 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21609 Remove unneeded casts.
21611 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21613 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21615 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21616 binding" message (bug#7967).
21618 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21620 Fix more problems found by GCC 4.6.0's static checks.
21622 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21623 Remove unused local var.
21625 * editfns.c (Fmessage_box): Remove unused local var.
21627 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21628 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21629 Omit unused local vars.
21630 * window.c (shrink_windows): Omit unused local var.
21631 * menu.c (digest_single_submenu): Omit unused local var.
21632 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21633 Omit unused local var.
21635 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21636 Don't assume string length fits in int.
21637 (keyremap_step, read_key_sequence): Use size_t for sizes.
21638 (read_key_sequence): Don't check last_real_key_start redundantly.
21640 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21641 instead of alloca (Bug#8344).
21643 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21644 (Fbacktrace_frame): Don't assume nframes fits in int.
21646 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21651 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21653 * cm.c (calccost): Turn while-do into do-while, for clarity.
21655 * keyboard.c (syms_of_keyboard): Use the same style as later
21656 in this function when indexing through an array. This also
21657 works around GCC bug 48267.
21659 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21661 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21663 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21664 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21666 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21667 This avoids undefined behavior on integer overflow, and is a bit
21668 more convenient anyway since it is compared to a size_t variable.
21670 Variadic C functions now count arguments with size_t, not int.
21671 This avoids an unnecessary limitation on 64-bit machines, which
21672 caused (substring ...) to crash on large vectors (Bug#8344).
21673 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21674 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21675 All variadic functions and their callers changed accordingly.

21682 * fns.c (concat): Likewise.
21683 * frame.c (x_set_frame_parameters): Likewise.
21684 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21685 0 if not found, not -1. All callers changed.
21687 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21688 (stack_copy_size): Now size_t, not int.
21689 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21691 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21693 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21694 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21695 All callers changed.
21697 * lisp.h (multibyte_char_to_unibyte):
21698 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21699 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21703 * keymap.c (push_key_description):
21704 * search.c (Freplace_match):
21705 * xdisp.c (message_dolog, set_message_1): All callers changed.
21707 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21709 * keyboard.c (safe_run_hook_funcall): New function.
21710 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21711 don't set the hook to nil, but remove the offending function instead.
21712 (Qcommand_hook_internal): Remove, unused.
21713 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21714 Vcommand_hook_internal.
21716 * eval.c (enum run_hooks_condition): Remove.

21902 Fix more problems found by GCC 4.5.2's static checks.
21904 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21905 the first time through the loop, since we know p0 < p1 then.
21906 This also avoids a gcc -Wstrict-overflow warning.
21908 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21909 leading to a memory leak, possible in functions like
21910 load_charset_map_from_file that can allocate an unbounded number
21911 of objects (Bug#8318).
21913 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21914 that could (at least in theory) be that large.
21916 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21917 This is less likely to overflow, and avoids undefined behavior if
21918 overflow does occur. All callers changed. Use strtoul to scan

21936 * process.c (Fmake_network_process): Use socklen_t, not int,
21937 where POSIX says socklen_t is required in portable programs.
21938 This fixes a porting bug on hosts like 64-bit HP-UX, where
21939 socklen_t is wider than int (Bug#8277).
21940 (Fmake_network_process, server_accept_connection):
21941 (wait_reading_process_output, read_process_output):

21954 Make tparam.h and terminfo.c consistent.
21955 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21956 Include tparam.h instead, since it declares them.
21957 * cm.h (PC): Remove extern decl; tparam.h now does this.
21958 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21959 * terminfo.c: Include tparam.h, to check interfaces.
21960 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21961 (tparam): Adjust signature to match interface in tparam.h;
21962 this removes some undefined behavior. Check that outstring and len
21963 are zero, which they always are with Emacs.
21964 * tparam.h (PC, BC, UP): New extern decls.
21966 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21967 (xftfont_open): Rename locals to avoid shadowing.

21985 (composition_update_it): Mark var as initialized.
21986 (find_automatic_composition): Mark vars as initialized,
21987 with a FIXME (Bug#8290).

22007 (alsa_choose_format): Remove unused local var.
22008 (wav_play): Initialize a variable to 0, to prevent undefined
22009 behavior (Bug#8278).
22011 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22013 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22015 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22016 clobbering (Bug#8298).
22017 * sysdep.c (sys_subshell): Likewise.
22018 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22020 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22021 This should get cleaned up, so that child_setup has the
22022 same signature on all platforms.
22024 * callproc.c (call_process_cleanup): Now static.
22025 (relocate_fd): Rename locals to avoid shadowing.
22027 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22029 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22030 not to be necessary, and produces flickering.
22032 2011-03-20 Glenn Morris <rgm@gnu.org>
22034 * config.in: Remove file.
22036 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22087 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22089 * deps.mk (unexalpha.o): Remove; unused.

22169 gcc -Wbad-function-cast warning.
22170 (default_value, arithcompare, arith_driver, arith_error): Now static.
22171 (store_symval_forwarding): Rename local to avoid shadowing.
22172 (Fmake_variable_buffer_local, Fmake_local_variable):

22179 (mark_stack): Move local variables into the #ifdef region where
22181 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22182 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22184 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22185 (GC_STRING_CHARS): Remove; not used.
22186 (Fmemory_limit): Cast sbrk's returned value to char *.
22188 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22189 avoids undefined behavior in theory.
22191 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22193 Use functions, not macros, for up- and down-casing (Bug#8254).
22194 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22195 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22196 to use the following functions instead of these macros.
22197 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22198 EMACS_INT, since callers assume the returned value fits in int.
22199 (upcase1): Likewise, for UPCASE_TABLE.
22200 (uppercasep, lowercasep, upcase): New static inline functions.
22201 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
22202 the race-condition problem in the old DOWNCASE.
22204 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
22205 Rename locals to avoid shadowing.
22206 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
22207 (regex_compile, re_search_2, re_match_2_internal):
22208 Remove unused local vars.

22210 which gcc can warn about.
22211 (regex_compile, re_match_2_internal): Mark locals as initialized.
22212 (RETALLOC_IF): Define only if needed.
22213 (WORDCHAR_P): Likewise. This one is never needed, but is used
22214 only in a comment talking about a compiler bug, so put inside
22215 the #if 0 of that comment.
22216 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22217 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22220 * search.c (boyer_moore): Rename locals to avoid shadowing.
22221 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

22243 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22244 New macros, so that the caller can use some names other than
22245 gcpro1, gcpro2, etc.
22246 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22248 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22249 argument, for consistency with GCPRO2_VAR, etc: it is now the
22250 prefix of the variable, not the variable itself. All uses
22252 * dired.c (directory_files_internal, file_name_completion):
22253 Rename locals to avoid shadowing.
22255 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22256 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22257 dired.c's scmp function, had undefined behavior.
22258 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22259 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22260 * buffer.h: ... to here, because these macros use current_buffer,
22261 and the new implementation with inline functions needs to have
22262 current_buffer in scope now, rather than later when the macros
22264 (downcase, upcase1): New static inline functions.
22265 (DOWNCASE, UPCASE1): Reimplement using these functions.
22266 This avoids undefined behavior in expressions like
22267 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22268 from race conditions in accessing the global variables
22269 case_temp1 and case_temp2.
22270 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22271 * lisp.h (case_temp1, case_temp2): Remove their decls.
22272 * character.h (ASCII_CHAR_P): Move from here ...
22273 * lisp.h: ... to here, so that the inline functions mentioned
22274 above can use them.
22276 * dired.c (directory_files_internal_unwind): Now static.
22278 * fileio.c (file_name_as_directory, directory_file_name):
22279 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22281 (file_name_as_directory): Use const pointers when appropriate.
22282 (Fexpand_file_name): Likewise. In particular, newdir might
22283 point at constant storage, so make it a const pointer.
22284 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22285 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22287 (Fset_file_times, Finsert_file_contents, auto_save_error):

22292 to avoid shadowing.
22294 * marker.c (bytepos_to_charpos): Remove; unused.
22296 * lisp.h (verify_bytepos, count_markers): New decls,
22297 so that gcc does not warn that these functions aren't declared.
22299 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22300 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22301 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22302 (copy_text): Remove unused local var.
22304 * filelock.c (within_one_second): Now static.
22305 (lock_file_1): Rename local to avoid shadowing.
22307 * buffer.c (fix_overlays_before): Mark locals as initialized.
22308 (fix_start_end_in_overlays): Likewise. This function should be
22309 simplified by using pointers-to-pointers, but that's a different
22311 (switch_to_buffer_1): Now static.
22312 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22313 (report_overlay_modification): Rename locals to avoid shadowing.
22315 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22316 Fix pointer signedness issue.
22317 (sys_subshell): Mark local as volatile if checking for lint,
22318 to suppress a gcc -Wclobbered warning that does not seem to be right.
22319 (MAXPATHLEN): Define only if needed.
22321 * process.c (serial_open, serial_configure): Move decls from here ...
22322 * systty.h: ... to here, so that they can be checked.
22324 * fns.c (get_random, seed_random): Move extern decls from here ...
22325 * lisp.h: ... to here, so that they can be checked.
22327 * sysdep.c (reset_io): Now static.
22328 (wait_for_termination_signal): Remove; unused.
22330 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22335 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22336 (describe_map_tree):
22337 Rename locals to avoid shadowing.
22339 * keyboard.c: Declare functions static if they are not used elsewhere.

22488 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
