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

139 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
141 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
142 * filelock.c: Include <c-ctype.h>.
143 (MAX_LFINFO): New top-level constant.
144 (lock_info_type): Remove members pid, boot_time. Add members at,
145 dot, colon. Change user member to be the entire buffer, not a
146 pointer. This allows us to handle the case where a foreign
147 pid or boot time exceeds the local range. All uses changed.
148 (LINKS_MIGHT_NOT_WORK): New constant.
149 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
150 (defined_WINDOWSNT): Remove.
151 (MAKE_LOCK_NAME, file_in_lock_file_name):
152 Always use .#FILE (not .#-FILE) for the file lock,
153 even if it is a regular file.
154 (rename_lock_file): New function.
155 (create_lock_file): Use it.
156 (create_lock_file, read_lock_data):
157 Prefer a symbolic link for the lock file, falling back on a
158 regular file if symlinks don't work. Do not try to create
159 symlinks on MS-Windows, due to security hassles. Stick with
160 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
161 link, rename, unlink, mkstemp) when creating locks, as a GNUish
162 host may be using a Windowsish file system, and cannot use
163 MS-Windows-only system calls. Fall back on mktemp if mkstemp
164 doesn't work. Don't fail merely because of a symlink-contents
165 length limit in the current file system; fall back on regular
166 files. Increase the symlink contents length limit to 8 KiB, this
167 should be big enough for any real use and doesn't crunch the
169 (create_lock_file, lock_file_1, read_lock_data):
170 Simplify allocation of lock file buffers now that they fit in 8 KiB.
171 (lock_file_1): Return error number, not bool. All callers changed.
172 (ELOOP): New macro, if not already defined.
173 (read_lock_data): Return size of lock file contents, not Lisp object.
174 All callers changed. Handle a race condition if some other process
175 replaces a regular-file lock with a symlink lock or vice versa,
176 while we're trying to read the lock.
177 (current_lock_owner): Parse contents more carefully, to help avoid
178 confusing a regular-file lock with some other application's use
179 of the file. Check for lock file contents being too long, or
180 not parsing correctly.
181 (current_lock_owner, lock_file):
182 Allow foreign pid and boot times that exceed the local range.
183 (current_lock_owner, lock_if_free, lock_file):
184 Simplify allocation of lock file contents.
185 * w32.c (sys_rename_replace): New function, containing most of
186 the contents of the old sys_rename.
187 (sys_rename): Use it.
188 (fchmod): New dummy function.
189 * w32.h (sys_rename_replace, fchmod): New decls.
191 2013-03-05 Eli Zaretskii <eliz@gnu.org>
193 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
194 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
195 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
196 <dmantipov@yandex.ru>.
198 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
200 * composite.c (get_composition_id, fill_gstring_header):
201 Use make_uninit_vector where appropriate.
202 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
203 * xselect.c (clean_local_selection_data): Likewise.
205 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
207 Fix misuse of ImageMagick that caused core dump (Bug#13846).
208 * image.c (imagemagick_load_image): Calculate height and width
209 after flattening the image, not before.
211 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
213 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
214 * ftfont.c (ftfont_shape_by_flt): Likewise.
215 * w32uniscribe.c (uniscribe_shape): Likewise.
217 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
219 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
220 The old approach, which fell back on DIR/.#FILE.0 through
221 DIR/.#FILE.9, had race conditions that could not be easily fixed.
222 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
223 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
224 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
225 because the locking mechanism was never reliable in that case).
226 This patch fixes this and other bugs discovered by a code
227 inspection that was prompted by
228 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
229 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
230 to avoid interoperability problems between the MS-Windows and
231 non-MS-Windows implementations. MS-Windows and non-MS-Windows
232 instances of Emacs now ignore each others' locks.
233 * filelock.c (defined_WINDOWSNT): New constant.
234 (MAKE_LOCK_NAME, fill_in_lock_file_name):
235 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
236 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
237 regular files on MS-Windows hosts.
238 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
239 Use SAFE_ALLOCA to avoid problems with long file names.
240 (MAX_LFINFO): Now a local constant, not a global macro.
241 (IS_LOCK_FILE): Remove.
242 (lock_file_1): Don't inspect errno if symlink call succeeds;
244 (lock_file): Document that this function can return if lock
246 (lock_file): Don't access freed storage.
248 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
250 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
252 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
254 * textprop.c: Use bool for booleans.
255 (validate_interval_range, Fadd_text_properties)
256 (Fremove_text_properties): Prefer bool to int when either works.
258 2013-03-02 Eli Zaretskii <eliz@gnu.org>
260 * textprop.c (Fadd_text_properties, Fremove_text_properties): If
261 the interval tree changes as a side effect of calling
262 modify_region, re-do processing starting from the call to
263 validate_interval_range. (Bug#13743)
265 2013-02-28 Eli Zaretskii <eliz@gnu.org>
267 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
270 2013-02-27 Eli Zaretskii <eliz@gnu.org>
272 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
273 _SH_DENYRW flag, instead of emacs_open, to deny any other process
274 access to the lock file until it is written and closed.
277 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
279 * callint.c (Qcall_interactively):
280 * macros.c (Qexecute_kbd_macro):
283 2013-02-26 Bastien Guerry <bzg@gnu.org>
285 * window.c (Frecenter): Tiny docstring enhancement.
287 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
289 Minor textprop integer cleanup.
290 * intervals.h, textprop.c (add_text_properties_from_list):
291 Return void, not int, since nobody uses the return value.
292 * textprop.c (validate_plist, add_properties, remove_properties)
293 (Fadd_text_properties):
294 Don't assume list length fits in int.
295 (interval_has_all_properties, interval_has_some_properties)
296 (interval_has_some_properties_list, add_properties, remove_properties)
297 (Fadd_text_properties, Fremove_text_properties)
298 (Fremove_list_of_text_properties, text_property_stickiness):
299 Use bool for booleans.
300 (Fadd_text_properties, Fremove_text_properties):
301 (Fremove_list_of_text_properties):
302 Reindent do-while as per GNU style.
304 2013-02-25 Eli Zaretskii <eliz@gnu.org>
306 Implement CLASH_DETECTION for MS-Windows.
308 * filelock.c [WINDOWSNT]: Include w32.h.
309 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
310 function of that name. Up-case the macro arguments.
311 (IS_LOCK_FILE): New macro.
312 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
313 (create_lock_file): New function, with body extracted from
315 [WINDOWSNT]: Implement lock files by writing a regular file with
316 the lock information as its contents.
317 (read_lock_data): New function, on Posix platforms just calls
319 [WINDOWSNT]: Read the lock info from the file.
320 (current_lock_owner): Call read_lock_data instead of calling
321 emacs_readlinkat directly.
322 (lock_file) [WINDOWSNT]: Run the file name through
325 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
326 just check if the process by that PID exists.
328 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
329 also present, as doing so will fail to error out if the file
332 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
334 * textprop.c (Fadd_text_properties, Fremove_text_properties)
335 (Fremove_list_of_text_properties): Skip all of the intervals in
336 the region between START and END that already have resp. don't
337 have the requested properties, not just the first one. Add
338 assertions that the loop afterwards always modifies the
339 properties. (Bug#13743)
341 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

372 (POINTER): Remove; all uses removed.
373 (data_space_start): Now char *, to avoid casts.
374 (exceeds_lisp_ptr): New function, replacing the old

470 2013-02-16 Eli Zaretskii <eliz@gnu.org>
472 * w32.c (sys_chown): Remove unused function.
474 * w32term.c <input_signal_count>: Declare 'volatile'
475 unconditionally. (Bug#9066)
477 * w32.c (set_errno): Reset h_errno and don't set it to any other
478 value. Set errno instead.
479 (check_errno): Reset h_errno.
480 (sys_socket, socket_to_fd, sys_bind, sys_connect)
481 (sys_gethostname, sys_getservbyname, sys_getpeername)
482 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
483 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
485 (sys_gethostbyname): Set h_errno only errors detected.
487 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
489 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
491 2013-02-15 Eli Zaretskii <eliz@gnu.org>
493 * keyboard.c (read_char): Fix calculation of auto-save time out
494 when auto-save-timeout is less than 4. (Bug#13720)
496 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
497 time. Improve diagnostics in DebPrint. (Bug#13546)

500 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
501 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
502 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
503 make sure errno is set to an appropriate value. (Bug#13546)
504 (socket_to_fd): Add assertion against indexing fd_info[] with a
505 value that is out of bounds.
506 (sys_accept): If fd is negative, do not set up the child_process
507 structure for reading.
509 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
511 * composite.c (fill_gstring_header): Remove useless prototype.
513 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
514 * print.c (PRINTDECLARE, print_object):
515 * search.c (compile_pattern, fast_looking_at, search_buffer):
516 (simple_search, boyer_moore, Freplace_match):

518 (get_overlay_arrow_glyph_row, display_mode_element):
519 (decode_mode_spec_coding, message3):
520 * xfaces.c (face_at_string_position): Use bool for booleans.
523 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
525 Fix AIX port (Bug#13650).
526 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
527 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
528 was #undeffed earlier, so it cannot be used as a macro here.
529 Use the constant and not the macro.
531 2013-02-15 Eli Zaretskii <eliz@gnu.org>
533 * w32proc.c (new_child): If no vacant slots are found in
534 child_procs[], make another pass looking for slots whose process
535 has exited or died. (Bug#13546)
537 * w32.c (sys_pipe): When failing due to file descriptors above
538 MAXDESC, set errno to EMFILE.
539 (_sys_read_ahead): Update cp->status when failing to read serial
540 communications input, so that the status doesn't stay at
541 STATUS_READ_IN_PROGRESS. (Bug#13546)
543 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
545 * gtkutil.c (tb_size_cb): New function.
546 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
548 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
550 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
553 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
555 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
557 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
559 * font.c (font_range): Add pos_byte argument. Adjust comment
561 * font.h (font_range): Adjust prototype.
562 * composite.c (autocmp_chars): Pass byte position to font_range.
563 Break long line. Remove useless prototype and format comment.
565 2013-02-13 Glenn Morris <rgm@gnu.org>
567 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
569 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
571 Improve AIX port some more (Bug#13650).
572 With this, it should be as good as it was in 23.3, though it's
573 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
574 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
575 * unexaix.c (start_of_text): Remove.
576 (_data, _text): Declare as char[], not int, as AIX manual suggests.
577 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
578 (orig_load_scnptr, orig_data_scnptr):
579 Now off_t, not long, since they are file offsets.
580 (make_hdr): Use _data, not start_of_data ().
581 This is the key part of the fix.
582 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
583 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
585 * pre-crt0.c (data_start): Initialize to 1.
586 This ports to compilers that optimize the external declaration
587 'int x = 0;' as if it were 'int x;' to shrink the executable.
589 Improve AIX port (Bug#13650).
590 This doesn't fix the bug, but it makes progress: Emacs builds now.
591 * unexaix.c: Include inttypes.h, stdarg.h.
592 (report_error, report_error_1): Mark as _Noreturn.
593 (report_error): Don't report the wrong errno.
594 (report_error_1): Now varargs. All callers changed.
595 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
596 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
597 (write_ptr): Use %p to print address rather than %lx and a cast
598 to unsigned long. Grow buffer a bit, to be safer.
600 2013-02-13 Eli Zaretskii <eliz@gnu.org>
602 * bidi.c (bidi_resolve_neutral): After finding the next
603 non-neutral character, accept NEUTRAL_ON type as well, because
604 directional control characters, such as LRE and RLE, have their
605 type converted to that by bidi_resolve_weak. This avoids aborts
606 when LRE/RLE follows a run of neutrals.
607 (bidi_move_to_visually_next): Assert that return value of
608 bidi_peek_at_next_level is non-negative. Negative values will
611 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
613 Minor getenv-related fixes.
614 * callproc.c (Fcall_process_region) [!DOS_NT]:
615 Avoid unnecessary duplicate call to getenv.
616 * callproc.c (init_callproc):
617 * dispnew.c (init_display):
618 * sysdep.c (sys_subshell):
619 Omit unnecessary cast of getenv or egetenv.
621 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
623 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
626 2013-02-12 Eli Zaretskii <eliz@gnu.org>
628 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
630 (display_line): Set w->region_showing to the value of
631 it->region_beg_charpos, not to -1. This fixes redisplay
632 optimization when cursor is moved up after M->. (Bug#13623)
634 (try_scrolling): Scroll text up more if point is too close to ZV
635 and inside the scroll margin. This makes sure point is moved
636 outside the scroll margin in these cases.
638 * window.h (struct window): region_showing can no longer be
641 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
643 Tune by using memchr and memrchr.
644 * doc.c (Fsnarf_documentation):
645 * fileio.c (Fsubstitute_in_file_name):
646 * search.c (find_newline, scan_newline):
647 * xdisp.c (pos_visible_p, display_count_lines):
648 Use memchr and memrchr rather than scanning byte-by-byte.
649 * search.c (find_newline): Rename from scan_buffer.
650 Omit first arg TARGET, as it's always '\n'. All callers changed.
652 Clean up read_key_sequence a tiny bit more.
653 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
654 (read_key_sequence): Remove unused locals.
656 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
658 Clean up read_key_sequence a bit; reread active keymaps after first event.
659 * keyboard.c (read_char, read_char_x_menu_prompt)
660 (read_char_minibuf_menu_prompt):
661 Replace nmaps+maps with a single `map' arg.
662 (follow_key): Operate on a single map.
663 (active_maps): New function.
664 (test_undefined): Also return true for nil bindings.
665 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
666 a single (composed) keymap. Remember `first_event' to choose the right
667 set of active keymaps. Recompute the set of keymaps after receiving
668 the first event. Remove GOBBLE_FIRST_EVENT.
669 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
670 * keyboard.h (read_char): Update declaration.
671 * lread.c (read_filtered_event): Adjust call to read_char.
673 2013-02-11 Eli Zaretskii <eliz@gnu.org>
675 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
676 Don't use the limitation on backwards movement when lines are truncated
677 in the window. (Bug#13675)
679 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
681 * marker.c (set_marker_internal): If desired position is passed
682 as a marker, avoid call to buf_charpos_to_bytepos.
683 * window.c (Fset_window_point): Omit redundant type checking.
684 (Fset_window_start): Likewise. Format comment.
685 (window_scroll_pixel_based): Use set_marker_restricted_both
686 with character and byte positions obtained from an iterator.
687 (Fset_window_configuration): Use set_marker_restricted_both.
688 * xdisp.c (message_dolog): Likewise.
690 2013-02-10 Eli Zaretskii <eliz@gnu.org>
692 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
693 When text lines are longer than window's screen lines, don't move back
694 too far. This speeds up some redisplay operations. (Bug#13675)
696 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
698 * syntax.c (scan_sexps_forward): Fix byte position calculation
699 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
701 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
703 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
706 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
708 Minor hashing refactoring.
709 * fns.c (SXHASH_REDUCE): Move to lisp.h.
710 (sxhash_float): Return EMACS_UINT, for consistency with the other
712 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
713 non-static inline function and therefore can't use static vars.
714 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
715 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
716 with the other hash functions.
718 2013-02-09 Eli Zaretskii <eliz@gnu.org>
720 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
721 XXXXXX part of the temporary file pattern is not downcased even
722 when w32-downcase-file-names is non-nil. (Bug#13661)
724 * xdisp.c (decode_mode_spec): Remove handling of %t.
726 * msdos.c (careadlinkatcwd): Remove.
728 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
730 * lread.c (skip_dyn_bytes): New function (bug#12598).
731 (read1): Use it. Use getc instead of READCHAR to read bytes.
732 (load_each_byte): Remove. Update users.
734 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
736 * search.c (scan_buffer): Calculate end byte position just once.
737 (scan_newline): Do not recalculate start_byte.
738 (search_command): Use eassert.
739 * syntax.c (struct lisp_parse_state): New member location_byte.
740 (scan_sexps_forward): Record from_byte and avoid redundant
741 character to byte position calculation ...
742 (Fparse_partial_sexp): ... here. Break too long line.
744 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
746 * lisp.h (make_uninit_vector): New function.
747 * alloc.c (Fvector, Fmake_byte_code):
748 * ccl.c (Fregister_ccl_program):
749 * charset.c (Fdefine_charset_internal, define_charset_internal):

759 * window.c (Fcurrent_window_configuration):
760 * xfaces.c (Fx_family_fonts):
761 * xselect.c (selection_data_to_lisp_data): Use it.
763 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
765 * coding.c (Fdefine_coding_system_internal): Use AREF where
766 argument is known to be a vector.
767 * fns.c (Flocale_info): Likewise for ASET.
768 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
769 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
771 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
773 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
776 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
777 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
778 updateCollectionBehaviour.
780 * nsterm.m (NEW_STYLE_FS): Remove.
781 (ns_last_use_native_fullscreen): New variable.
782 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
783 (x_set_window_size): Do not take title bar and tool bar into account
784 if isFullscreen returns YES.
785 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
786 (check_native_fs): New function.
787 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
788 (ns_term_init): Remove NEW_STYLE_FS.
789 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
790 and tool bar if isFullscreen returns NO.
791 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
792 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
794 (window:willUseFullScreenPresentationOptions:): New method.
795 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
796 Hide toolbar if not enabled (Bug#13444).
797 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
798 Restore tool bar if enabled, hide it otherwise (Bug#13444).
799 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
800 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
801 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
802 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
803 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
804 (syms_of_nsterm): Add ns-use-native-fullscreen.
806 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
808 * fileio.c (Qchoose_write_coding_system): Now static.
810 2013-02-04 Eli Zaretskii <eliz@gnu.org>
812 * xdisp.c (window_buffer_changed): region_showing can be negative,
813 which still means region is being displayed.
814 (redisplay_internal): Resurrect code that forced redisplay of the
815 whole window when showing region and the mark has changed.
816 Record the new mark position to allow redisplay optimizations.
817 (display_line): If it->region_beg_charpos is non-zero, set the
818 window's region_showing member to -1. (Bug#13623) (Bug#13626)
820 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
821 not bitfield of 1 bit.
823 2013-02-03 Daniel Colascione <dancol@dancol.org>
825 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
826 daemon mode works on cygw32 when Emacs is installed and not just
829 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
831 Avoid file time stamp bug on MS-Windows (Bug#13149).
832 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
833 as FAT32 doesn't update time stamps when truncating them.
834 Also, check that a file time stamp is not a multiple of 100 ns;
835 this should catch all instances of the problem on MS-Windows,
836 as its native file system resolution is 100 ns or worse, and
837 checking for a non-multiple of 100 ns should impose only a small
838 overhead on systems with ns resolution.
840 2013-02-02 Eli Zaretskii <eliz@gnu.org>
842 Avoid encoding file names on MS-Windows when they need to be run
843 through dostounix_filename.
844 * w32.c (normalize_filename): Accept an additional argument
845 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
846 downcase it even if w32-downcase-file-names is non-nil.
847 (dostounix_filename): Accept an additional argument MULTIBYTE and
848 pass it to normalize_filename.
849 (emacs_root_dir): Adjust.
851 * msdos.h (dostounix_filename): Adjust prototype.
853 * w32.h (dostounix_filename): Adjust prototype.
855 * msdos.c (dostounix_filename): Accept an additional argument and
857 (init_environment): Adjust callers of dostounix_filename.
859 * fileio.c (Ffile_name_directory, file_name_as_directory)
860 (directory_file_name, Fexpand_file_name)
861 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
863 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
865 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
866 variables, as egetenv is case-insensitive for DOS_NT.
868 * dired.c (file_name_completion): Don't call Fdirectory_file_name
869 with an encoded file name.
871 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
872 Adjust calls to dostounix_filename.
874 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
876 * unexw32.c (unexec): Adjust call to dostounix_filename.
878 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
880 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
883 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
886 * callproc.c (Fcall_process): Make sure program name in PATH and
887 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
888 is passed to exec/spawnve, which fails unless the file-name
891 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
892 even if w32-quote-process-args is nil.
894 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
896 Fix timestamp bug when write-region appends nothing (Bug#13149).
897 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
898 the file's time stamp doesn't change if Emacs happens to write nothing
899 to the file, and on a buggy file system this could cause Emacs to
900 incorrectly infer that the file system doesn't have the bug.
901 Avoid this problem by inhibiting the inference in this case.
903 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
905 * window.h (struct window): Convert base_line_number, base_line_pos
906 and column_number_displayed members from Lisp_Object to ptrdiff_t.
907 Convert region_showing member from Lisp_Object to bitfield.
908 Remove sequence_number member. Adjust comments.
909 * window.c (sequence_number): Remove.
910 (make_window): Initialize column_number_displayed.
911 * print.c (print_object): Follow the printed representation of
912 frames and print window pointer to distinguish between windows.
913 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
914 * xdisp.c (wset_base_line_number, wset_base_line_pos)
915 (wset_column_number_displayed, wset_region_showing): Remove.
916 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
917 (try_scrolling, try_cursor_movement, redisplay_window)
918 (try_window_reusing_current_matrix, try_window_id, display_line)
919 (display_mode_lines, decode_mode_spec): Adjust users.
920 * .gdbinit (pwinx): Do not print sequence_number.
922 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
924 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
925 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
926 * dired.c: Include <fcntl.h>.
927 (open_directory): New function, which uses open and fdopendir
928 rather than opendir. DOS_NT platforms still use opendir, though.
929 (directory_files_internal, file_name_completion): Use it.
930 (file_attributes): New function, with most of the old Ffile_attributes.
931 (directory_files_internal, Ffile_attributes): Use it.
932 (file_attributes, file_name_completion_stat): First arg is now fd,
933 not dir name. All uses changed. Use fstatat rather than lstat +
935 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
936 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
937 (emacs_readlinkat): New function, with much of the old
938 Ffile_symlink_p, but with an fd argument for speed.
939 It uses readlinkat rather than careadlinkatcwd, so that it
940 need not assume the working directory.
941 (Ffile_symlink_p): Use it.
942 * filelock.c (current_lock_owner): Use emacs_readlinkat
943 rather than emacs_readlink.

963 (sys_close): Zero out the flags for the file descriptor before
964 closing it. (Bug#13546)
966 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
967 (logon_network_drive, stat_worker, symlink, chase_symlinks):
968 Use CharNextExA and CharPrevExA to iterate over file names encoded in
971 * w32.c (w32_get_long_filename, init_environment, readlink):
972 Support file names encoded in DBCS codepages.
973 (readlink): Use the current file-name-coding-system, not the ANSI
974 codepage, to decode and handle targets of symlinks.
976 2013-01-28 Eli Zaretskii <eliz@gnu.org>
978 * w32.c (opendir): Now accepts a 'const char *'.

982 Remove obsolete redisplay code. See the discussion at
983 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
984 * dispnew.c (preemption_period, preemption_next_check): Remove.
985 (Vredisplay_preemption_period): Likewise.
986 (update_frame, update_single_window, update_window, update_frame_1):
987 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
988 used, following the 2012-06-22 change.
990 2013-01-25 Eli Zaretskii <eliz@gnu.org>
992 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
994 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
996 * font.c (num_fonts): Remove the leftover from old
997 debugging code. Adjust comment style here and there.

1002 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1004 * w32.c (max_filename_mbslen): New function.
1005 (normalize_filename, readdir): Use it to detect locales where ANSI
1006 encoding of file names uses a double-byte character set (DBCS).
1007 If a DBCS encoding is used, advance by characters using
1008 CharNextExA, instead of incrementing a 'char *' pointer.
1009 Use _mbslwr instead of _strlwr. (Bug#13515)
1011 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1012 request of memory reservation to 1.7GB. (Bug#13065)
1014 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1016 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1017 at check_extra_latin label. (Bug#13505)
1019 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1021 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1022 Avoid redundant calls to strlen.
1024 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1026 Drop async_visible and async_iconified fields of struct frame.
1027 This is possible because async input is gone; for details, see
1028 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1029 * frame.h (struct frame): Remove async_visible and async_iconified
1030 members, convert garbaged to unsigned bitfield. Adjust comments.
1031 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1032 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1033 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1034 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1035 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1037 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1038 properly. Likewise for obscured.
1040 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1043 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1045 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1047 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1048 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1050 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1052 * xdisp.c (message2, message2_nolog): Remove functions.
1053 (message3, message3_nolog): Extract nbytes and multibyteness directly
1054 from the string. Change all callers.
1055 (message3_nolog): Don't set message_enable_multibyte since set_message
1056 will reset it anyway.
1057 (message1, message1_nolog): Use message3.
1058 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1059 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1060 (set_message): Drop all but the second arg, which has to be a string.
1061 (set_message_1): Simplify now that we know that a1 is NULL and the
1062 second arg is a string.
1063 * frame.h (struct frame): Remove `message_buf' field.
1064 Use glyphs_initialized_p instead.
1065 (FRAME_MESSAGE_BUF): Remove macro.

1074 * editfns.c (message_text, message_length): Remove vars.
1075 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1076 * fileio.c (auto_save_error): Use message3 instead of message2.
1077 * dispnew.c (adjust_frame_message_buffer): Remove function.
1079 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1081 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1082 real estate used for the tool bar and the menu bar.
1084 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1086 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1087 hidden buffer is prepared to modification (Bug#13164).
1089 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1091 * window.h (struct window): Change window_end_valid member from
1092 Lisp_Object to a bitfield. Adjust comments.
1093 (wset_window_end_valid): Remove.
1094 * window.c (adjust_window_count): Clear window_end_valid.

1099 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1100 * xdisp.c (check_window_end, reconsider_clip_changes)
1101 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1102 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1103 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1105 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1107 * xdisp.c (mark_window_display_accurate): Simplify the loop
1108 assuming that the only one of vchild, hchild or buffer window
1109 slots is non-nil. Call mark_window_display_accurate_1 for
1110 the leaf windows only.
1111 (mark_window_display_accurate_1): Always assume leaf window.
1114 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1116 * emacs.c (Qkill_emacs_hook): Now static.
1118 * fileio.c (Finsert_file_contents): Simplify.
1119 Remove unnecessary assignments and tests.
1121 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1123 * w32.c (acl_set_file): Don't test for errors unless
1124 set_file_security returns FALSE. Avoids spurious errors when
1127 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1129 * fileio.c (Finsert_file_contents): Revert code introduced at
1130 2013-01-18 in favor of the simpler and generally better fix.
1131 Save stack space by removing 'buffer' and reusing 'read_buf'
1134 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1136 * lisp.h (eabs): Define unconditionally (Bug#13419).
1137 The old "#if !defined (eabs)" was an unnecessary revenant of back
1138 when this macro was called "abs". Document 'eabs' better.
1140 2013-01-19 Glenn Morris <rgm@gnu.org>
1142 * fns.c (Frandom): Doc fix.
1144 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1146 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1147 segfault when there are lots of overlays.
1149 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1150 when there are lots of overlays.
1151 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1152 for the details and a way to reproduce.
1154 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1156 * fileio.c: Use O_APPEND to append.
1157 This corresponds better to the natural interpretation of "append",
1158 and avoids the need to open the output file twice, or to invoke
1159 lseek when APPEND is neither nil nor a number.
1160 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1161 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1162 file possibly twice, and lseeking to its end; this avoids the
1163 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1164 at the same time: the combination is never needed and apparently
1165 it doesn't work with DOS_NT.
1167 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1168 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1170 Allow floating-point file offsets.
1171 Problem reported by Vitalie Spinu in
1172 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1173 * fileio.c (emacs_lseek): Remove.
1174 (file_offset): New function.
1175 (Finsert_file_contents, Fwrite_region): Use it.
1177 2013-01-19 Chong Yidong <cyd@gnu.org>
1179 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1180 aborting on Fsignal (Bug#13289).
1182 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1184 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1185 set_file_security as failure due to insufficient privileges.
1186 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1187 (fstat): Return owner and group like 'stat' and 'lstat' do.
1189 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1191 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1192 The bug was observed on Ubuntu operating inside a virtual machine,
1193 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1194 The workaround introduces a race condition on non-buggy hosts,
1195 but it's an unlikely race and anyway there's a nearly identical
1196 nearby race that can't be fixed.
1197 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1199 (Fwrite_region): Test for file system time stamp bug.
1200 (init_fileio): New function.
1201 * lisp.h (init_fileio): Declare it.
1202 * emacs.c (main): Call it.
1204 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1205 and make it more consistent with other stat-failure diagnostics.
1207 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1209 Fix crash when inserting data from non-regular files.
1210 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1211 for the error description produced by valgrind.
1212 * fileio.c (read_non_regular): Rename to read_contents.
1213 Free Lisp_Save_Value object used to pass parameters.
1214 (read_non_regular_quit): Rename to read_contents_quit.
1215 (Finsert_file_contents): Redesign internal file reading loop to adjust
1216 gap and end positions after each read and so help make_gap to work
1217 properly. Do not signal an I/O error too early and so do not leave
1218 not yet decoded characters in a buffer, which was the reason of
1219 redisplay crash. Use list2 to build return value. Adjust comments.
1221 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1223 Close a race when statting and reading files (Bug#13149).
1224 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1225 This avoids a race if the file is renamed between stat and open.
1226 This race is not the problem originally noted in Bug#13149;
1227 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1229 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1236 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1237 * alloc.c (format_save_value): Rename to make_save_value.
1238 (make_save_pointer): New function.
1239 (record_xmalloc): Use make_save_pointer.
1240 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1241 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1242 Change users of make_save_value to make_save_pointer.
1243 Likewise for format_save_value and make_save_value.

1259 (map_keymap_char_table_item): Adjust accordingly.
1260 * fileio.c (non_regular_fd, non_regular_inserted)
1261 (non_regular_nbytes): Remove.
1262 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1263 Use format_save_value to pass parameters to read_non_regular.
1264 (read_non_regular): Use XSAVE_ macros to extract parameters.
1266 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1268 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1270 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1272 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1273 extraction from any Lisp_Save_Value slot. Add type checking.
1274 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1275 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1276 * xselect.c: All users changed.
1278 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1289 (save_excursion_restore): Use XSAVE_OBJECT.
1291 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1293 Avoid needless casts with XSAVE_POINTER.
1294 * alloc.c (mark_object) [GC_MARK_STACK]:
1295 * dired.c (directory_files_internal_unwind):
1296 * fileio.c (do_auto_save_unwind):
1297 * gtkutil.c (pop_down_dialog):
1298 * keymap.c (map_keymap_char_table_item):
1299 * lread.c (load_unwind):
1300 * nsmenu.m (pop_down_menu):
1301 * print.c (print_object) [GC_MARK_STACK]:
1302 * xfns.c (clean_up_file_dialog):
1303 * xmenu.c (cleanup_widget_value_tree):
1304 Omit casts between XSAVE_POINTER and a pointer type.
1306 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

1309 * eval.c (eval_sub): Protect `form' from being GCed before its
1310 car and cdr becomes protected with the backtrace entry.

1320 (free_misc): Likewise.
1321 * alloc.c (allocate_misc): Now global.
1322 (free_misc): Likewise. Adjust comment.
1323 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1324 (free_save_value): Likewise.
1325 (mark_object): Likewise.
1326 * editfns.c (save_excursion_save): Pack everything within
1327 Lisp_Save_Value and so avoid xmalloc.
1328 (save_excursion_restore): Adjust to match new layout. Use free_misc
1329 because we do not allocate extra memory any more. Add eassert.
1330 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1331 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1332 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,

1385 Clear tzvalbuf_in_environ if this workaround is in effect.
1386 Problem and fix reported by Kazuhiro Ito.
1388 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

1397 string cross-reference(s).
1399 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1401 Avoid unnecessary byte position calculation for the gap movement.
1402 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1403 anyway, all of them should use move_gap_both instead.
1404 * lisp.h (move_gap): Remove prototype.
1405 * insdel.c (move_gap): Remove.
1406 (move_gap_both): Add eassert.

1412 emacsclient -t should not suspend Emacs server (Bug#13387)
1413 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1415 * term.c (init_tty): Use them instead of rolling our own code.
1416 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1417 switches from 'signal' to 'pthread_sigmask', which is safer in
1418 multithreaded applications.
1419 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1420 which has already arranged for that.
1421 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1422 This is the main part of the bug fix.

1434 predicate, which is how it's really used now. Adjust comment.
1435 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1436 * buffer.c (buffer_slot_type_mismatch): Remove.
1437 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1438 predicate. Adjust comment.

1441 left-margin-width, right-margin-width, left-fringe-width,
1442 right-fringe-width, scroll-bar-width and buffer-display-count.
1443 Use Qstringp for default-directory, buffer-file-name,
1444 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1445 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1447 * data.c (store_symval_forwarding): Adjust to call the predicate.

1463 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1464 (make_gap_1): New function to adjust the gap of any buffer.
1465 * coding.c (coding_alloc_by_making_gap): Use it.
1466 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1467 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1469 2013-01-08 Juri Linkov <juri@jurta.org>

1483 2013-01-06 Chong Yidong <cyd@gnu.org>
1485 * keyboard.c (echo_add_char): New function, factored out from

1490 trailing dash is properly added.
1492 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1494 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1495 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1496 digits for buffer positions, before misalignment starts.
1497 Display "0" for integer "object" field.
1498 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1499 Display the newline glyph more unambiguously.
1501 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1503 * nsterm.m (ns_draw_underwave):
1504 * w32term.c (w32_draw_underwave):
1505 * xterm.c (x_draw_underwave): Make underwave look more triangular
1506 and also degrade gracefully for small fonts. (Bug#13000)
1508 * nsterm.m (ns_draw_text_decoration):
1509 * w32term.c (x_draw_glyph_string):
1510 * xterm.c (x_draw_glyph_string): Don't use previous underline
1511 thickness and position if previous underline type is underwave.
1513 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1515 * fileio.c (Ffile_acl): Undocument return format.
1517 2013-01-02 Glenn Morris <rgm@gnu.org>
1519 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
1521 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>

1528 * fringe.c (compute_fringe_widths):
1529 * lread.c (read_list):
1530 * minibuf.c (Ftry_completion):
1531 * term.c (tty_ins_del_lines):
1532 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1533 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1535 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1537 * w32.c (unsetenv): Set up the string passed to _putenv
1539 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1540 for the bug this caused.
1542 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1544 * coding.c (Qmac): Now static.
1546 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1548 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1549 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1552 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
1553 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1554 Show all on TOOLBAR_TOP_WIDGET.
1555 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1556 by TOOLBAR_TOP_WIDGET.
1557 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1558 Check toolbar_is_packed.
1559 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1561 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1563 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1564 (xg_update_menubar): Update title only if
1565 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1566 (xg_update_submenu): Skip tearoff only if
1567 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1568 (xg_initialize): Initialize xg_detached_menus only if
1569 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1571 * xterm.h (struct x_output): Surround handlebox_widget with
1572 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1573 toolbar_in_hbox is bool.
1575 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1577 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1578 (LIBS_GNUSTEP): Define.
1579 (LIBES): Add $(LIBS_GNUSTEP).
1580 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1582 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1584 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1585 continuation glyph on a TTY with an indication of an empty line.
1588 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1590 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1591 file's SELinux context or ACLs successfully set, nil otherwise.
1593 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1595 * w32proc.c (reader_thread): Avoid passing NULL handles to
1596 SetEvent and WaitForSingleObject.
1598 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1600 Port EXTERNALLY_VISIBLE to Clang 3.2.
1601 * conf_post.h (__has_attribute): New macro.
1602 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1604 2012-12-27 Glenn Morris <rgm@gnu.org>
1606 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1607 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1609 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1611 * fileio.c (file_name_as_directory, directory_file_name):
1612 Accept an additional argument MULTIBYTE to indicate whether the input C
1613 came from a multibyte or a unibyte Lisp string; all callers
1614 adjusted. Don't assume the input string is always multibyte.
1616 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1617 don't ENCODE_FILE them, and return a unibyte string if the input
1619 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1620 don't assume the input strings will always be multibyte. If the
1621 input strings are multibyte, decode strings obtained from C
1624 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1626 * lisp.h (toplevel): Add two notices to the comment about
1627 defining a new Lisp data type.

1631 * alloc.c (valid_lisp_object_p): Adjust comment.
1633 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1635 * keyboard.c (record_asynch_buffer_change): Initialize an event
1636 only if it's really needed.
1637 * frame.h (enum output_method): Remove output_mac member since
1638 it's a leftover from the deleted code.
1639 * frame.c (Fframep): Adjust user here ...
1640 * terminal.c (Fterminal_live_p): ... and here.
1641 * coding.c (Qmac): Now here because it's only used to denote
1642 end-of-line encoding type.
1643 (syms_of_coding): DEFSYM it.
1644 * frame.h (Qmac): Remove duplicated declaration.
1646 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1648 * window.c (select_window_1): Now static, since it's used only here.
1650 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1652 * window.c (window_body_cols): Subtract display margins from the
1653 window body width on TTYs as well. See
1654 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1655 for the original report.
1657 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1659 * xdisp.c (redisplay_window): Remove inner local variable
1660 because the outer shadowed one has the same meaning.
1661 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1663 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1664 (xg_create_tool_bar): Adjust users.
1666 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1668 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1669 * buffer.c (Fget_buffer_create): Use it to set compact field of
1670 struct buffer_text to avoid accessing an uninitialized value
1671 when compact_buffer is called for the first time.
1672 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1673 (Fset_buffer_modified_p): Use buffer_window_count to check
1674 whether the buffer is displayed in some window.
1675 * xdisp.c (message_dolog): Likewise.
1677 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1679 * w32.c (acl_set_file): If setting the file security descriptor
1680 fails, and the new DACL is identical to the existing one, silently
1681 return success. This fixes problems for users backing up their
1682 own files without having the necessary privileges for setting
1683 security descriptors.
1685 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1687 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1688 after WaitForSingleObject returns normally. This expedites reader
1689 thread shutdown when delete_child triggers it.
1690 (reap_subprocess): More accurate commentary for why we call
1691 delete_child only when cp->fd is negative.
1693 * w32.c (sys_close): Do not call delete_child on a subprocess
1694 whose handle is not yet closed. Instead, set its file descriptor
1695 to a negative value, so that reap_subprocess will call
1696 delete_child on that subprocess when its SIGCHLD arrives.
1697 This avoids closing handles used for communications between sys_select
1698 and reader_thread, which doesn't give sys_select a chance to
1699 notice that the process exited and invoke the SIGCHLD handler for
1702 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1704 * nsfns.m (Fns_do_applescript): Run event loop until script has
1705 been executed (Bug#12969).

1711 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1713 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1715 * w32term.c (w32fullscreen_hook): New function.
1716 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1718 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1720 * fileio.c (Finsert_file_contents): Doc fix.
1722 * w32proc.c (new_child, delete_child, find_child_pid): For a
1723 subprocess, consider its slot being in use as long as its process
1724 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1725 slot when a new process is started immediately after killing
1726 another one, without waiting enough time for the first process to
1727 be reaped and resources allocated for it be orderly freed.
1729 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1731 2012-12-21 Chong Yidong <cyd@gnu.org>
1733 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1735 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1737 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1739 * w32.c (get_name_and_id): Always pass NULL as the first argument
1740 of lookup_account_sid. Avoids crashes with UNC file names that
1741 refer to DFS domains, not to specific machine names. (Bug#12621)
1742 Remove now unused argument FNAME; all callers changed.
1743 (get_file_owner_and_group): Remove now unused argument FNAME; all
1746 2012-12-21 Chong Yidong <cyd@gnu.org>
1748 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1749 error for invalid chars, don't check for a nil return value.
1751 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1753 Avoid calls to CHAR_TO_BYTE if byte position is known.
1754 * editfns.c (make_buffer_string_both): Use move_gap_both.
1755 (Fbuffer_string): Use make_buffer_string_both.
1756 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1758 (buf_bytepos_to_charpos): Likewise.
1759 (charpos_to_bytepos): Remove.
1760 * fileio.c (Finsert_file_contents): Use move_gap_both.
1761 * search.c (Freplace_match): Likewise.
1762 * process.c (process_send_region): Likewise. Use convenient
1763 names for byte positions.
1764 * lisp.h (charpos_to_bytepos): Remove prototype.
1765 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1766 * insdel.c (move_gap): Likewise.

1772 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1774 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1775 (redisplay_internal): Don't bother selecting the frame to get the
1776 proper value of frame-local variables (bug#13225).
1778 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1780 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1781 Rename 4th argument since it may be buffer or string. Adjust comment.
1782 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1784 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1786 * coding.c (Fdetect_coding_region): Do not check start and end with
1787 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1788 (code_convert_region): Likewise.
1790 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1792 * w32.c (acl_get_file, acl_set_file): Run the file name through
1793 map_w32_filename, and resolve any symlinks in the file name, like
1795 (acl_set_file): Call revert_to_self, if any privileges were
1798 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1800 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1801 ($(BLD)/w32.$(O)): Update dependencies.
1803 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1805 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1806 propagate redisplay's scrolling (if any) to the right window.
1807 (redisplay_internal): Use ensure_selected_frame.
1808 (display_mode_lines): Complete last fix.
1809 * window.c (select_window_1): New func, extracted from select_window.
1810 (select_window): Use it.
1811 * window.h (select_window_1): Declare.
1813 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1815 Emulate Posix ACL APIs on MS-Windows.
1816 * w32.c: Include sddl.h and sys/acl.h.

1837 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1839 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1840 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1841 for some of that bug's symptoms can now cause Emacs to abort.
1842 Remove the workaround.
1843 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1844 The bug that caused SIGCHLD to get lost has been fixed, and the
1845 workaround for it can now cause Emacs to abort.
1847 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1849 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1850 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1851 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1853 2012-12-16 Romain Francoise <romain@orebokech.com>
1855 * fileio.c (Ffile_acl, Fset_file_acl): New functions.

1857 and copy ACL entries of file in addition to SELinux context if set.

1880 (record_infile, record_pending_deletion): New functions.
1881 (reap_subprocess): Fix a typo in DebPrint string.
1882 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1884 * fileio.c (internal_delete_file): Return an int again: non-zero
1885 if delete-file succeeds, zero otherwise.
1887 * lisp.h (internal_delete_file): Adjust prototype.
1889 * callproc.c (Fcall_process): Don't overwrite infile with result
1891 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1892 asynchronous subprocess, record the name of the input file name,
1894 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1895 delete the file, record it as pending deletion when the subprocess
1898 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1900 * editfns.c [HAVE_PWD_H]: Include grp.h.

1906 Fix permissions bugs with setgid directories etc. (Bug#13125)
1907 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1908 to mark it as a placeholder. The old value was often wrong.
1909 The only user of this attribute has been changed to use
1910 file-ownership-preserved-p instead, with its new group arg.
1911 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1918 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1920 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1921 try to get accurate owner and group information from NT file
1922 security APIs. This is to make most callers of 'stat' and
1923 'lstat', which don't need that information, much faster.
1925 * dired.c (Ffile_attributes) [WINDOWSNT]:
1926 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1927 owner and group information from 'lstat'.
1929 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1931 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1932 as that confuses set-auto-coding, so insist on the head-read
1933 returning the full 1024 bytes. Let lseek compute the tail offset;
1934 less work for us. Do not ignore I/O errors when reading the tail.
1936 * xdisp.c: Minor style fixes.
1937 (init_iterator): Hoist assignment out of if-expression.
1938 (markpos_of_region): Callers now test for sign, not for -1.

1957 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1958 files, fixing a regression from 24.2.
1959 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1961 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1963 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1964 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1965 Remove unnecessary S_ISLNK test, as (contra the comments) this
1966 function can't copy symlinks. Improve quality of error message
1967 when attempting to copy files that are neither regular files nor

1976 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1978 2012-12-12 Daniel Colascione <dancol@dancol.org>
1980 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1981 the dumped Emacs is not a sparse file, greatly improving Cygwin
1982 "make bootstrap" performance.
1984 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1986 * inotify.c (inotify_callback): Generate an Emacs event for every
1987 incoming inotify event.
1989 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1991 * xdisp.c (handle_face_prop): Fix logic of computing
1992 it->start_of_box_run_p.
1993 (append_space_for_newline): If the glyph row is R2L, reset the
1994 iterator's end_of_box_run_p flag before prepending the space glyph.
1995 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1996 iterator's start_of_box_run_p flag before prepending the stretch.

1998 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1999 left_box_line_p and right_box_line_p flags of the glyph for R2L
2000 glyph rows. (Bug#13011)

2007 * window.c (replace_buffer_in_windows_safely): Do nothing
2008 if buffer is not shown in a window.

2014 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2015 encoded_file_name, which is what it is.
2017 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2019 Consistently use marker_position and marker_byte_position.
2020 * fringe.c (Ffringe_bitmaps_at_pos):

2046 * w32fns.c (cache_system_info): Initialize the global hinst
2047 variable here so various initialization calls DTRT.
2049 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2050 (hinst): Remove unneeded extern declaration.
2051 (_start): Remove initialization of above variables; remove
2052 initialization of hinst, as cache_system_info now does that.

2271 * frame.c (make_frame): Do not set window's buffer to t.
2272 * window.c (Fsplit_window_internal): Likewise. Previously it was
2273 used to indicate that the window is being set up. Now we use

2275 (Fset_window_buffer): ... is always true and can be removed.
2277 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2279 Convenient macro to check whether the buffer is hidden.

2293 * frame.h (x_char_width, x_char_height): Remove prototypes.

2307 * callproc.c, process.h (record_kill_process):
2308 New function, containing part of the old call_process_kill.
2309 (call_process_kill): Use it.
2310 This does not change call_process_kill's behavior.
2311 * process.c (Fdelete_process): Use record_kill_process to fix a
2312 race condition that could cause Emacs to lose track of a child.
2314 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2316 Avoid code duplication between prev_frame and next_frame.
2317 * frame.c (candidate_frame): New function. Add comment.

2322 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2323 fails, signal an error instead of continuing with an empty
2325 Encode expanded temp file pattern before passing it to mkstemp or
2328 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2329 Encode the file name before passing it to dostounix_filename, in
2330 case it will downcase it (under w32-downcase-file-names).
2333 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2335 Minor call-process cleanups.
2336 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2337 at the same time as other platforms, to simplify analysis.
2338 No need for fd0_volatile since we have synch_process_fd.
2339 Avoid needless emacs_close; arg is always negative.
2341 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2343 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2346 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2348 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2349 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2350 and mouse_face_hidden members to a bitfields.
2351 * frame.h (struct frame): Remove set-but-not-used space_width member.
2352 (FRAME_SPACE_WIDTH): Remove.

2354 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2355 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2356 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2357 members to a bitfields.
2359 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2361 Don't let call-process be a zombie factory (Bug#12980).
2362 Fixing this bug required some cleanup of the signal-handling code.
2363 As a side effect, this change also fixes a longstanding rare race
2364 condition whereby Emacs could mistakenly kill unrelated processes,
2365 and it fixes a bug where a second C-g does not kill a recalcitrant
2366 synchronous process in GNU/Linux and similar platforms.
2367 The patch should also fix the last vestiges of Bug#9488,
2368 a bug which has mostly been fixed on the trunk by other changes.
2369 * callproc.c, process.h (synch_process_alive, synch_process_death)
2370 (synch_process_termsig, sync_process_retcode):
2371 Remove. All uses removed, to simplify analysis and so that
2372 less consing is done inside critical sections.
2373 * callproc.c (call_process_exited): Remove. All uses replaced
2374 with !synch_process_pid.
2375 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2376 These take the role of what used to be in unwind-protect arg.
2378 (block_child_signal, unblock_child_signal):
2379 New functions, to avoid races that could kill innocent-victim processes.
2380 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2381 (call_process_kill): Record killed processes as deleted, so that
2382 zombies do not clutter up the system. Do this inside a critical
2383 section, to avoid a race that would allow the clutter.
2384 (call_process_cleanup): Fix code so that the second C-g works again
2385 on common platforms such as GNU/Linux.
2386 (Fcall_process): Create the child process in a critical section,
2387 to fix a race condition. If creating an asynchronous process,
2388 record it as deleted so that zombies do not clutter up the system.
2389 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2390 light of these changes. Omit unnecessary call to emacs_close
2391 before failure, as the unwind-protect code does that.
2392 * callproc.c (call_process_cleanup):
2393 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2394 * process.c (record_deleted_pid): New function, containing
2395 code refactored out of Fdelete_process.
2396 (Fdelete_process): Use it.
2397 (process_status_retrieved): Remove. All callers changed to use
2398 child_status_change.
2399 (record_child_status_change): Remove, folding its contents into ...
2400 (handle_child_signal): ... this signal handler. Now, this
2401 function is purely a handler for SIGCHLD, and is not called after
2402 a synchronous waitpid returns; the synchronous code is moved to
2403 wait_for_termination. There is no need to worry about reaping
2404 more than one child now.
2405 * sysdep.c (get_child_status, child_status_changed): New functions.
2406 (wait_for_termination): Now takes int * status and bool
2407 interruptible arguments, too. Do not record child status change;
2408 that's now the caller's responsibility. All callers changed.
2409 Reimplement in terms of get_child_status.
2410 (wait_for_termination_1, interruptible_wait_for_termination):
2411 Remove. All callers changed to use wait_for_termination.
2412 * syswait.h: Include <stdbool.h>, for bool.
2413 (record_child_status_change, interruptible_wait_for_termination):
2415 (record_deleted_pid, child_status_changed): New decls.
2416 (wait_for_termination): Adjust to API changes noted above.
2418 * bytecode.c, lisp.h (Qbytecode): Remove.
2419 No longer needed after 2012-11-20 interactive-p changes.
2421 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2423 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2424 the scroll margin, move point outside the margin. (Bug#13055)

2433 * lisp.h (modify_region): Rename to...
2434 (modify_region_1): ...new prototype.
2435 * textprop.c (modify_region): Now static. Adjust users.
2436 * insdel.c (modify_region): Rename to...
2437 (modify_region_1): ...new function to work with current buffer.
2438 Adjust comment and users. Use true and false for booleans.
2440 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2442 * alloc.c (free_save_value): New function.
2443 (safe_alloca_unwind): Use it.
2444 * lisp.h (free_save_value): New prototype.
2445 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2447 (save_excursion_restore): Adjust to match saved data structure.
2448 Use free_save_value to offload some work from GC. Drop obsolete
2451 2012-12-03 Chong Yidong <cyd@gnu.org>
2453 * fileio.c (Vauto_save_list_file_name): Doc fix.
2455 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2457 * w32fns.c: Remove prototype of atof.
2458 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2460 (file_dialog_callback): Make it UINT_PTR.
2462 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2465 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2466 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2469 2012-12-03 Glenn Morris <rgm@gnu.org>
2471 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2473 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2475 Fix xpalloc confusion after memory is exhausted.
2476 * alloc.c (xpalloc): Comment fix.
2477 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2478 and signals an error, do not clear charset_table_size, as
2479 charset_table is still valid.
2480 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2482 Use execve to avoid need to munge environ (Bug#13054).
2483 * callproc.c (Fcall_process):
2484 * process.c (create_process):
2485 Don't save and restore environ; no longer needed.
2486 * callproc.c (child_setup):
2487 Use execve, not execvp, to preserve environ.
2489 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2491 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2493 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2495 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2496 display for sliced images (Bug#10500).
2498 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2500 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2502 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2503 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2505 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2507 * xdisp.c (window_outdated): Remove eassert since it hits
2508 some suspicious corner cases (see Bug#13007 and Bug#13012).
2509 (mode_line_update_needed): New function.
2510 (redisplay_internal, redisplay_window): Use it.
2511 (ensure_selected_frame): New function.
2512 (redisplay_internal, unwind_redisplay): Use it.
2513 (redisplay_internal): Move comment about buffer_shared...
2514 (buffer_shared_and_changed): ...near to its real use.
2516 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2518 * callproc.c (Fcall_process): Don't misreport vfork failure.
2520 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2522 * callproc.c (Fcall_process): Fix vfork portability problems.
2523 Do not assume that fd[0], count, filefd, and save_environ survive
2524 vfork. Fix bug whereby wrong errno value could be reported for
2525 pipe failure. Some minor cleanups, too, as follows. Move buf and
2526 bufsize to the context where they're needed. Change new_argv to
2527 be of type char **, as this is more convenient and avoids casts.
2528 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2529 Now local constants, not macros.
2531 2012-11-18 Kenichi Handa <handa@gnu.org>
2533 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2534 for the variable "f".
2536 2012-11-13 Kenichi Handa <handa@gnu.org>
2538 * font.c (font_unparse_xlfd): Exclude special characters from the
2539 generating XLFD name.
2541 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2565 highlighting on the frame was cleared. Prevents assertion
2566 violations when repeatedly clicking on the "Top" link of the
2567 "bread-crumbs" in Info buffers.

2581 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2582 between bpos_covered and bpos_max. This fixes cursor display when
2583 several display strings follow each other.
2585 * .gdbinit (pgx): If the glyph's object is a string, display the
2586 pointer to string data, rather than the value of the string object
2587 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2589 * indent.c (Fvertical_motion): If the starting position is covered
2590 by a display string, return to one position before that, to avoid
2591 overshooting it inside move_it_to. (Bug#12930)
2593 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2612 of a literal "/". (Bug#12955)
2613 (gl-stamp): Invoke fc.exe directly, not through cmd.

2618 * dired.c: Assume HAVE_DIRENT_H.
2619 (NAMLEN): Remove, replacing with ...
2620 (dirent_namelen): New function. All uses changed. Use the GNU macro
2621 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2622 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2623 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2624 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2626 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.

2629 Do not include <dirent.h>; no longer needed.
2630 * w32.c: Include <dirent.h> rather than "ndir.h".
2632 2012-11-23 Chong Yidong <cyd@gnu.org>
2634 * xftfont.c (xftfont_open): Remove duplicate assignment.
2636 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2638 * alloc.c (Fgarbage_collect): Unblock input after clearing
2639 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2640 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2641 * msdos.c (IT_frame_up_to_date): Use it here...
2642 * w32term.c (w32_frame_up_to_date): ...here...

2658 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2660 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts

2686 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2688 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2689 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2690 Define for the MSVC compiler.
2692 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

2697 dostounix_filename assumes it gets a unibyte string.
2698 Reported by Michel de Ruiter <michel@sentient.nl>, see

2747 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2749 * w32select.c: Include w32common.h before w32term.h, so that
2750 windows.h gets included before w32term.h uses some of its
2751 features, see below.
2753 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2755 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2788 (create_pty, Fmake_network_process, server_accept_connection)

2793 It's not clear this is needed, but it's a more-conservative change.
2794 (create_process): Assume FD_CLOEXEC.
2795 (create_process, create_pty): Assume O_NOCTTY.
2796 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2797 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2798 Omit if not DOS_NT, since F_GETFL is not defined there.
2799 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2800 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2802 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2803 lack it, since gnulib guarantees this.
2804 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2806 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2808 * w32.c (faccessat): Pretend that directories have the execute bit
2809 set. Emacs expects that, e.g., in files.el:cd-absolute.
2811 * w32proc.c (create_child): Don't clip the PID of the child
2812 process to fit into an Emacs integer, as this is no longer a
2814 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2815 reaping only the process specified by PID argument, if that is
2816 positive. Use PID instead of dead_child to know which process to
2817 reap. Wait for the child to die only if WNOHANG is not in
2819 (sys_select): Don't set dead_child.
2821 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2822 as it is no longer needed.
2824 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2826 (record_child_status_change): Remove the setting of
2827 record_at_most_one_child for the !WNOHANG case.
2829 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2831 Fix problems in ns port found by static checking.
2832 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2833 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2834 not to process group.
2835 (ns_select): Use emacs_write, not write, as that's more robust
2836 in the presence of signals.
2837 (fd_handler:): Check for read errors.
2839 2012-11-16 Glenn Morris <rgm@gnu.org>
2841 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2843 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2845 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2847 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2849 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2850 use the same value of thread handle.
2851 (start_timer_thread): If the timer thread exited (due to error),
2852 clean up by closing the two handles it used. Duplicate the caller
2853 thread's handle here, so it gets duplicated only once, when
2854 launching the timer thread. Set priority of the timer thread, not
2856 (getitimer): Don't duplicate the caller thread's handle here.
2859 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2861 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2864 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2866 Remove no-longer-used pty_max_bytes variable.
2867 * process.c (pty_max_bytes): Remove; unused.
2868 (send_process): Do not set it.
2870 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2872 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2873 Update dependencies.
2875 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2877 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2878 This follows up on the 2012-09-29 patch that removed indirection
2879 for the 'function' field. Reported by Sergey Vinokurov in
2880 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2882 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2884 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2885 different name, as the MS runtime does not have such a function,
2886 and probably never will.) All callers changed. Ignore DIRFD
2887 value if PATH is an absolute file name, to match Posix spec
2888 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2891 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2893 * xdisp.c (echo_area_display, redisplay_internal):
2894 Omit redundant check whether frame_garbaged is set.
2896 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2898 Use faccessat, not access, when checking file permissions (Bug#12632).
2899 This fixes a bug that has been present in Emacs since its creation.
2900 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2901 which must set some sort of record. (Torek's bug report was against
2902 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2903 same common flaw.) See Torek's Usenet posting
2904 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2905 Posted: Fri Apr 8 14:18:56 1983.
2906 * Makefile.in (LIB_EACCESS): New macro.
2908 * callproc.c (init_callproc):
2909 * charset.c (init_charset):
2910 * fileio.c (check_existing, check_executable, check_writable)
2912 * lread.c (openp, load_path_check):
2913 * process.c (allocate_pty):
2915 Use effective UID when checking permissions, not real UID.
2916 * callproc.c (init_callproc):
2917 * charset.c (init_charset):
2918 * lread.c (load_path_check, init_lread):
2919 Test whether directories are accessible, not merely whether they exist.
2920 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2921 * fileio.c (check_existing, check_executable, check_writable)
2923 Use symbolic names instead of integers for the flags, as they're
2925 (check_writable): New arg AMODE. All uses changed.
2926 Set errno on failure.
2927 (Ffile_readable_p): Use faccessat, not stat + open + close.
2928 (Ffile_writable_p): No need to call check_existing + check_writable.
2929 Just call check_writable and then look at errno. This saves a syscall.
2930 dir should never be nil; replace an unnecessary runtime check
2931 with an eassert. When checking the parent directory of a nonexistent
2932 file, check that the directory is searchable as well as writable, as
2933 we can't create files in unsearchable directories.
2934 (file_directory_p): New function, which uses 'stat' on most platforms
2935 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2936 (Ffile_directory_p, Fset_file_times): Use it.
2937 (file_accessible_directory_p): New function, which uses a single
2938 syscall for efficiency.
2939 (Ffile_accessible_directory_p): Use it.
2940 * xrdb.c (file_p): Use file_directory_p.
2941 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2942 * lread.c (openp): When opening a file, use fstat rather than
2943 stat, as that avoids a permissions race. When not opening a file,
2944 use file_directory_p rather than stat.
2945 (dir_warning): First arg is now a usage string, not a format.
2946 Use errno. All uses changed.
2947 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2948 that merely introduced a race.
2949 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2950 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2951 and similarly for the other O_* flags.
2952 * w32.c (sys_faccessat): Rename from sys_access and switch to
2953 faccessat's API. All uses changed.
2954 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2955 (magic_db): Rename from magic_file_p.
2956 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2957 char *, so that we don't have to test for file existence
2958 separately from opening the file for reading. This removes a race
2959 fixes a permission-checking problem, and simplifies the code.
2961 (file_p): Remove; no longer needed.
2963 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2965 Omit glyphs initialization at startup.
2966 * dispnew.c (glyphs_initialized_initially_p): Remove.
2967 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2968 (Fredraw_frame): Move actual code from here...
2969 (redraw_frame): ...to here. Add eassert. Adjust comment.
2970 (Fredraw_display): Use redraw_frame.
2971 * xdisp.c (clear_garbaged_frames): Likewise.
2973 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2975 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2976 passed to pint2str and pint2hrstr to be at most the size of the
2977 frame's decode_mode_spec_buffer. This avoids crashes with very
2978 large values of FIELD_WIDTH argument to decode_mode_spec.
2981 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2983 Fix a race with verify-visited-file-modtime (Bug#12863).
2984 Since at least 1991 Emacs has ignored an mtime difference of no
2985 more than one second, but my guess is that this was to work around
2986 file system bugs that were fixed long ago. Since the race is
2987 causing problems now, let's remove that code.
2988 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2989 whose time stamp is off by no more than a second. Insist that the
2990 file time stamps match exactly.
2992 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2994 * frame.h (struct frame): Convert external_tool_bar member to
2995 1-bit unsigned bitfield.
2996 * termhooks.h (struct terminal): Remove mouse_moved member since
2997 all users are long dead. Adjust comment on mouse_position_hook.
2999 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3001 Simplify by using FOR_EACH_FRAME here and there.
3002 * frame.c (next_frame, prev_frame, other_visible_frames)
3003 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3004 * w32term.c (x_window_to_scroll_bar): Likewise.
3005 * window.c (window_list): Likewise.
3006 * xdisp.c (x_consider_frame_title): Likewise.
3007 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3008 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3009 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3010 * xmenu.c (menubar_id_to_frame): Likewise.
3011 * xselect.c (frame_for_x_selection): Likewise.
3012 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3013 (x_window_to_menu_bar): Likewise.
3014 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3016 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3018 * data.c (Qdefalias_fset_function): Now static.
3020 Another tweak to vectorlike_header change.
3021 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3022 Remove, and replace all uses with ...
3023 (next_in_free_list, set_next_in_free_list):
3024 New functions, which respect C's aliasing rules better.
3026 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3028 * window.c (list4i): Rename from 'quad'. All uses changed.
3029 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3031 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3033 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3034 warning about mixing declarations and code in ISO C90.
3036 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3038 * window.c (Fsplit_window_internal): Set combination limit of
3039 new parent window to t iff Vwindow_combination_limit is t;
3040 fixing a regression introduced with the change from 2012-09-22.
3041 (Fset_window_combination_limit): Fix doc-string.
3043 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3045 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3046 amount when the scroll margins are too large. When scrolling
3047 backwards in the buffer, give up if cannot reach point or the
3048 scroll margin within a reasonable number of screen lines.
3049 Fixes point position in window under scroll-up/down-aggressively when
3050 point is positioned many lines beyond the window top/bottom.
3053 * ralloc.c (relinquish): If real_morecore fails to return memory
3054 to the system, don't crash; instead, leave the last heap
3055 unchanged and return. (Bug#12774)
3057 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3059 * lisp.h (AUTOLOADP): New macro.
3060 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3061 * data.c (Ffset): Remove special ad-advice-info handling.
3062 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3064 (Finteractive_form): Simplify.
3065 (Fquo): Don't insist on having at least 2 arguments.
3066 (Qdefalias_fset_function): New var.
3068 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3070 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3072 * nsfont.m (Qcondensed, Qexpanded): New variables.
3073 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3074 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3076 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3078 Fix recently introduced crash on MS-Windows (Bug#12839).
3079 * w32term.h (struct scroll_bar): Use convenient header.
3080 (SCROLL_BAR_VEC_SIZE): Remove.
3081 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3083 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3085 Tweak last vectorlike_header change.
3086 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3087 vectorlike object on the free list. This is introduced to avoid
3088 some (but not all) pointer casting and aliasing problems, see
3089 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3090 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3092 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3094 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3096 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3097 been removed, so remove them here also.
3099 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3101 * doc.c (Fdocumentation): Handle new property
3102 dynamic-docstring-function to replace the old ad-advice-info.
3104 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3106 * fns.c (Qeql, hashtest_eq): Now static.
3108 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

3111 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3112 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3113 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3115 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3117 Use same hash function for hashfn_profiler as for hash_string etc.
3118 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3119 * lisp.h (sxhash_combine): New inline function, with the contents
3120 of the old SXHASH_COMBINE.
3121 * profiler.c (hashfn_profiler): Use it, instead of having a
3122 special hash function containing a comparison that always yields 1.
3124 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3126 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3127 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3128 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3131 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3133 * image.c (xpm_make_color_table_h): Fix compiler error because
3134 make_hash_table changed.

3143 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3144 (make_log): Use them.

3155 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3156 (hash_lookup, hash_remove_from_table): Move assertion checking of
3157 hashfn result here. Check hash-equality before calling cmpfn.

3167 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3169 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3170 value of w32-scroll-lock-modifier is neither nil nor one of the
3171 known key modifiers. (Bug#12806)
3173 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3175 Shrink struct vectorlike_header to the only size field.
3176 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3178 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3179 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3180 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3181 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3182 information from the vector header. Adjust comment.

3193 (NEXT_IN_FREE_LIST): New macro.
3194 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3195 (Fmake_bool_vector): Likewise.
3196 (struct large_vector): New type to represent allocation unit for
3197 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3198 (large_vectors): Change type to struct large_vector.
3199 (allocate_vector_from_block): Simplify.
3200 (PSEUDOVECTOR_NBYTES): Replace with...
3201 (vector_nbytes): ...new function. Adjust users.
3202 (sweep_vectors): Adjust processing of large vectors.

3208 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3209 * buffer.h (struct buffer): Add next member.
3210 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3212 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3213 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3214 (copy_hash_table): Adjust to match vector header change.
3215 * lread.c (defsubr): Use XSETPVECTYPE.
3216 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3217 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3218 (xvecsize): New command.
3220 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3222 * keyboard.c (event_to_kboard): Do not dereference
3223 frame_or_window field of SELECTION_REQUEST_EVENT
3224 and SELECTION_CLEAR_EVENT events (Bug#12814).
3225 * xterm.h (struct selection_input_event): Adjust comment.
3227 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3229 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3230 such as Scroll Lock, if the respective keys are treated as
3231 function keys, not as modifiers. This avoids destroying non-ASCII
3232 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3234 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3236 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.

3240 Restore some duplicate definitions (Bug#12814).
3241 This undoes part of the 2012-11-03 changes. Some people build
3242 with plain -g rather than with -g3, and they need the duplicate
3243 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3244 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3245 Define as macros, as well as as enums or as constants.
3247 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3249 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3250 to keypad keys (Bug#12816).
3252 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3254 Minor adjustments of recently-changed frame functions.
3255 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3256 known to be a frame (we're in the FRAMEP branch).
3257 * lisp.h (Qframep): Remove decl. frame.h declares this.
3258 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3259 since they're meant for Lisp fixnum values.
3261 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3263 * window.c (Fwindow_combination_limit): Revert to the only
3264 required argument and adjust docstring as suggested in
3265 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3266 by Martin Rudalics <rudalics@gmx.at>.
3268 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3270 Widely used frame validity and checking functions.
3271 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3272 * frame.c (decode_live_frame, decode_any_frame): New functions.
3273 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3274 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3275 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3276 (Fframe_pointer_visible_p): Use decode_any_frame.

3279 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3280 (Fframe_focus): Likewise. Allow zero number of arguments.
3282 (frame_buffer_list, frame_buffer_predicate): Remove.
3283 * lisp.h (frame_buffer_predicate): Remove prototype.
3284 * buffer.c (Fother_buffer): Use decode_any_frame.
3285 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3286 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3287 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3288 (Fclose_font, Ffont_info): Use decode_live_frame.
3289 * fontset.c (check_fontset_name): Likewise.
3290 * terminal.c (Fframe_terminal): Likewise.
3291 * w32fns.c (check_x_frame): Likewise.
3292 * window.c (Fminibuffer_window, Fwindow_at)
3293 (Fcurrent_window_configuration): Likewise.
3294 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3295 Likewise. Allow zero number of arguments. Adjust docstring.
3296 * dispnew.c (Fredraw_frame): Likewise.
3297 * xfaces.c (frame_or_selected_frame): Remove.
3298 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3299 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3300 (Fframe_face_alist): Use decode_live_frame.
3301 * xfns.c (check_x_frame): Likewise.
3303 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3305 * window.c (quad): New function.
3306 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3307 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3308 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3309 (Fwindow_line_height): Use it.
3310 (Fwindow_fringes): Use list3.
3311 (Fwindow_scroll_bars): Use list4.
3312 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3313 (Fwindow_combination_limit): Allow zero number of arguments.
3315 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3317 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3319 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3320 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3321 file descriptor 2 for standard error. (Bug#12805)
3323 2012-11-05 Chong Yidong <cyd@gnu.org>
3325 * process.c (wait_reading_process_output): Revert previous change.
3327 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3329 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3330 This removes code that has been obsolete since around 1990.
3331 * callproc.c (Fcall_process):
3333 * process.c (create_process):
3334 * term.c (dissociate_if_controlling_tty):
3335 Assume setsid exists.
3336 * callproc.c (child_setup): Assume setpgid exists and behaves as
3337 per POSIX.1-1988 or later.
3338 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3339 * emacs.c (shut_down_emacs):
3340 * sysdep.c (sys_suspend, init_foreground_group):
3341 Assume getpgrp behaves as per POSIX.1-1998 or later.
3342 * msdos.c (setpgrp): Remove.
3343 (tcgetpgrp, setpgid, setsid): New functions.
3344 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3345 * term.c (no_controlling_tty): Remove; unused.
3346 * w32proc.c (setpgrp): Remove.
3347 (setsid, tcgetpgrp): New functions.
3349 Simplify by assuming __fpending.
3350 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3351 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3352 Do not assume that __fpending's result fits in int.
3354 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3356 Remove EMACS_OUTQSIZE+sleep hack.
3357 * dispnew.c (update_frame_1): Remove hack for terminals slower
3358 than 2400 bps, which throttled Emacs by having it sleep.
3359 This code hasn't worked since at least 2007, when the multi-tty stuff
3360 was added, and anyway those old terminals are long dead.
3361 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3362 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3364 Fix data-loss with --version (Bug#9574).
3365 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3366 as we can't assume that emacs_strerror is initialized, and strerror
3367 is good enough here.
3368 (main): Invoke atexit earlier, to catch earlier instances of
3369 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3371 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3373 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3374 (keyDown): Remap keypad keys to X11 virtual key codes.
3376 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3378 Fix data-loss with --batch (Bug#9574).
3379 * emacs.c: Include <close-stream.h>.
3380 (close_output_streams): New function.
3381 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3382 and handles errors appropriately.
3383 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3386 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3387 The symptom is a diagnostic "GLib-WARNING **: In call to
3388 g_spawn_sync(), exit status of a child process was requested but
3389 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3390 waitpid(), so exit status can't be returned." The diagnostic
3391 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3392 The real bug is a race condition between Emacs and glib: Emacs
3393 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3394 so that glib can't find it. Work around the bug by invoking
3395 waitpid only on subprocesses that Emacs itself creates.
3396 * process.c (create_process, record_child_status_change):
3397 Don't use special value -1 in pid field, as the caller now must
3398 know the pid rather than having the callee infer it.
3399 The inference was sometimes incorrect anyway, due to another race.
3400 (create_process): Set new 'alive' member if child is created.
3401 (process_status_retrieved): New function.
3402 (record_child_status_change): Use it.
3403 Accept negative 1st argument, which means to wait for the
3404 processes that Emacs already knows about. Move special-case code
3405 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3406 processes that have already been waited for, by testing and
3407 clearing new 'alive' member.
3408 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3409 now does this internally.
3410 (handle_child_signal): Let record_child_status_change do all
3411 the work, since we do not want to reap all exited child processes,
3412 only the child processes that Emacs itself created.
3413 * process.h (Lisp_Process): New boolean member 'alive'.
3415 Omit duplicate definitions no longer needed with gcc -g3.
3416 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3417 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3418 Define only as macros. There's no longer any need to also define
3419 these symbols as enums or as constants, since we now assume
3420 gcc -g3 when debugging.
3422 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3424 * lisp.mk: Adjust comments to the fact that term/internal is now
3425 loaded from loadup.el.
3427 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3428 (msdos_fatal_signal): New function.
3429 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3432 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3433 for GCC versions before 4.
3434 (emacs_raise): Define to call msdos_fatal_signal.
3436 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3437 iterator when starting in the middle of a display or overlay
3440 2012-11-03 Chong Yidong <cyd@gnu.org>
3442 * process.c (wait_reading_process_output): Clean up the last
3445 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3447 * process.c (wait_reading_process_output): Avoid a race condition
3448 with SIGIO delivery (Bug#11536).
3450 2012-11-03 Chong Yidong <cyd@gnu.org>
3452 * buffer.c (cursor_type): Untabify docstring.
3454 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3456 * frame.h (struct frame): Drop can_have_scroll_bars member
3457 which is meaningless for a long time. Adjust comments.
3458 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3459 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3461 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3463 * window.c (decode_next_window_args): Update window arg after
3464 calling decode_live_window and so fix crash reported at
3465 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3466 by Juanma Barranquero <lekktu@gmail.com>.
3467 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3468 * font.c (Ffont_at): Likewise.
3470 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3472 * widget.c (resize_cb): New function.
3473 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3474 (EmacsFrameResize): Check if all is up to date before changing frame
3477 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3479 Implement backtrace output for fatal errors on MS-Windows.
3480 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3481 (BACKTRACE_LIMIT_MAX): New macro.
3482 (w32_backtrace): New function.
3483 (emacs_abort): Use w32_backtrace when the user chooses not to
3484 attach a debugger. Update the text of the abort dialog.
3486 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3488 Window-related stuff cleanup here and there.
3489 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3490 Use decode_any_window.
3491 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3492 * xdisp.c (Fformat_mode_line): Likewise.
3493 * font.c (Ffont_at): Use decode_live_window.
3494 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3495 * window.c (decode_next_window_args): Likewise.
3496 (decode_any_window): Remove static.
3497 * window.h (decode_any_window): Add prototype.
3498 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3499 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3502 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3504 Remove pad from struct input_event.
3505 * termhooks.h (struct input_event): Remove padding field.
3507 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3508 member is never cons for a long time. Adjust comment.
3509 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3510 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3511 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3512 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3514 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3516 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3518 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3520 Fix crash when using Emacs as commit editor for git (Bug#12697).
3521 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3522 and it is configured in conf_post.h.
3523 (Fcall_process): Don't invoke both setsid and setpgid; the former
3524 is enough, if it exists.
3525 * callproc.c (Fcall_process, child_setup):
3526 * process.c (create_process): Use setpgid.
3527 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3529 * dispnew.c (init_display): Initialize the foreground group
3530 if we are running a tty display.
3531 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3532 * lisp.h (init_foreground_group): New decl.
3533 * sysdep.c (inherited_pgroup): New static var.
3534 (init_foreground_group, tcsetpgrp_without_stopping)
3535 (narrow_foreground_group, widen_foreground_group): New functions.
3536 (init_sys_modes): Narrow foreground group.
3537 (reset_sys_modes): Widen foreground group.
3539 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3541 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3543 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3545 * minibuf.c (read_minibuf): Restore current buffer since
3546 choose_minibuf_frame calling Fset_frame_selected_window may
3547 change it (Bug#12766).
3549 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3551 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3553 2012-10-30 Kenichi Handa <handa@gnu.org>
3555 * font.c (Ffont_at): If WINDOW is specified and it is not
3556 displaying the current buffer, signal an error.
3558 2012-10-29 Daniel Colascione <dancol@dancol.org>
3560 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3561 In preparation for fixing bug#12739, move these functions from
3564 * coding.h, coding.c: ... to here, and compile them only when
3565 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3566 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3568 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3570 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3571 (timer_loop, getitimer, setitimer): Use it instead of
3572 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3574 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3577 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3579 * nsterm.m (NO_APPDEFINED_DATA): New define.
3580 (last_appdefined_event_data): New variable
3581 (last_appdefined_event): Remove.
3582 (ns_select): Initialize t from last_appdefined_event_data instead
3583 of [last_appdefined_event data1].
3584 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3585 remove last_appdefined_event (Bug#12698).
3587 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3589 * frame.c (x_set_font): Catch internal error.
3591 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3593 Avoid overflow in w32 implementation of interval timers.
3594 When possible, for ITIMER_PROF count only times the main thread
3596 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3597 'volatile ULONGLONG' types. All the other data which was
3598 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3599 (GetThreadTimes_Proc): New typedef.
3600 (w32_get_timer_time): New function, returns a suitable time value
3602 (timer_loop): Enter critical section when accessing ULONGLONG
3603 values of the itimer_data struct, as these accesses are no longer
3604 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3605 Remove unused variable.
3606 (init_timers): Initialize s_pfn_Get_Thread_Times.
3607 (start_timer_thread): Don't assign itimer->caller_thread here.
3608 (getitimer): Assign itimer->caller_thread here.
3609 (setitimer): Always call getitimer to get the value of ticks_now.
3610 (sys_spawnve): Avoid compiler warning about format mismatch.
3612 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3614 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3615 mouse movement events if the menu bar is active. This avoids
3616 producing a busy "hour-glass" cursor by Windows if the mouse
3617 pointer is positioned over a tooltip shown for some menu item.
3619 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3621 Don't assume process IDs fit in int.
3622 * emacs.c (shut_down_emacs) [!DOS_NT]:
3623 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3624 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3625 Use pid_t, not int, to store process IDs, as 'int'
3626 is not wide enough on a few platforms (e.g., AIX and IRIX).
3628 2012-10-23 Kenichi Handa <handa@gnu.org>
3630 The following change is to make face-font-rescale-alist work
3631 correctly for non-ASCII fonts.
3633 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3634 (font_open_for_lface): Handle Vface_font_rescale_alist.
3636 2012-10-23 Chong Yidong <cyd@gnu.org>
3638 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3640 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3642 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3644 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3646 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3649 2012-10-21 Glenn Morris <rgm@gnu.org>
3651 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3653 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3655 Port to OpenBSD 5.1.
3656 * frame.c (Fmouse_position, Fmouse_pixel_position):
3657 * xdisp.c (produce_stretch_glyph):
3658 Declare local vars only when they're needed.
3659 This is clearer and avoids a warning on OpenBSD about unused vars.
3660 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3661 This is safer, and avoids OpenBSD warnings about unused vars.
3662 * keyboard.c (record_menu_key): Remove unnecessary decl.
3663 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3664 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3665 as our definition clashes with OpenBSD's.
3666 * xfaces.c (load_face_colors, check_lface_attrs)
3667 (get_lface_attributes_no_remap, get_lface_attributes)
3668 (lface_fully_specified_p, x_supports_face_attributes_p)
3669 (tty_supports_face_attributes_p, face_fontset, realize_face)
3670 (realize_x_face, realize_tty_face):
3671 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3672 merely Lisp_Object *. This is more informative and avoids
3673 a warning on OpenBSD about accessing beyond an object's size.
3675 2012-10-20 Chong Yidong <cyd@gnu.org>
3677 * lread.c (Fload): Doc fix (Bug#12592).
3679 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3681 * font.c (Ffont_at): Fix previous change.

4164 (w32_strerror): Just what it says on the tin.
4166 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4167 also run for Cygwin; both systems have the same problem with using
4168 GUI facilities in a forked child. Also call syms_of_cygw32,
4169 syms_of_w32select in correct places.
4171 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4172 needs fork-then-exec for daemon launching.
4174 * font.h: Include frame.h.
4176 * image.c: Use the image library cache machinery only when we're
4177 compiling for native WINDOWSNT; Cygwin can use shared libraries
4178 like any other Unixlike system.
4180 * keyboard.c: Clarify a comment regarding the input loop.
4182 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4183 functions directly instead of trying to detect at runtime that our
4184 host operating system supports them. We make this change for two
4185 reasons: Cygwin lacks support for the multibyte character
4186 conversion functions used by the legacy menu code, and Cygwin
4187 never needs to rely on non-Unicode APIs.
4189 * unexw32.c (hinst): Declare extern.
4191 * w32.c: Change header order;
4192 (w32_strerror): Move to w32fns.c because we need it for
4193 non-WINDOWSNT builds.
4195 * w32.h: Add #error macro to make sure we don't include w32.h for
4196 Cygwin builds. Remove w32select declarations.
4198 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4199 w32fns.c. w32console.c is WINDOWSNT-only.
4201 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4202 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4204 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4205 (w32_major_version, w32_minor_version, w32_build_number)
4206 (os_subtype, sound_type): Define here
4207 (w32_defined_color): Make color parameter const for consistency
4208 with other _defined_color functions.
4209 (w32_createwindow): Unconditionally call w32_init_class instead of
4210 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4211 through the code is complex and unnecessary because class
4212 registration is practically free.
4213 (w32_name_of_message): New EMACSDEBUG-only function.
4214 (Fset_message_beep): Move here
4215 (Fx_open_connection): Require that the display name for Windows be
4216 "w32" for consistency, emacsclient disambiguation, and maybe, one
4217 day, multi-window-system support.
4218 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4219 Cygwin files for W32 GUI facilities, since these clearly don't
4220 expect Cygwin names.
4221 (_DebPrint): Define.
4222 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4223 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4224 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4225 (w32_last_error): Remove.
4227 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4229 * w32heap.c (syspage_mask): Declare here.
4230 (cache_system_info): Remove.
4232 * w32inevt.c (faked_key): Define globally, not statically.
4233 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4234 (w32_console_toggle_lock_key): Move to w32fns.c.
4236 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4238 * w32proc.c (_DebPrint): Move to w32fns.c.
4239 * w32select.c: Include string.h, stdio.h for Cygwin.
4240 * w32select.h: New File.
4242 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4244 (w32_message_fd): New variable. Under Cygwin, holds the file
4245 descriptor the system used to tell us about pending thread
4248 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4249 that prevented compilation under non-WINDOWSNT systems.
4251 (w32_initialize): Open /dev/windows and assign it to
4252 w32_message_fd. Provide w32 feature.
4254 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4255 (WM_EMACS_INPUT_READY): add.
4256 (prepend_msg, w32_message_fd): Declare globally.
4259 (keyboard_handle): Use only when WINDOWSNT.
4260 (notify_msg_ready): New function. Posts a message to the main
4261 thread's message queue under CYGWIN, which wakes up the main
4262 thread from select(2) by making the /dev/windows file descriptor
4263 ready. Under WINDOWSNT, it sets an event the same way the old
4266 (post, prepend_msg): Actually call notify_msg_ready instead of
4267 setting the input event directly.
4269 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4271 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4272 but it still has blocs in it, don't return it to the system,
4273 instead of aborting. (Bug#12402)
4275 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4277 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4279 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4280 MAC_OS_X_VERSION_10_6.
4281 (syms_of_nsterm): Remove comment about Panther and above for
4283 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4284 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4285 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4287 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4288 MAC_OS_X_VERSION_10_4.
4290 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4291 MAC_OS_X_VERSION_10_2.
4293 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4295 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4296 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4298 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4299 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4300 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4301 Remove ns_in_resize check.
4302 (ns_clear_frame_area): Remove resize handle code.
4304 * nsfns.m (ns_in_resize): Remove.
4305 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4306 Remove ns_in_resize check.
4308 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4310 Improve sys_siglist detection.
4311 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4312 defined as a macro, as is done in Solaris.
4313 (sys_siglist_entries): New macro.
4314 (save_strsignal): Use it.
4315 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4316 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4318 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4320 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4321 fullscreen/Fullscreen.
4323 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4324 tobar_height is new.
4326 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4327 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4328 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4329 (windowDidResize:): Check for correct window if old style fullscreen.
4330 Capitalize word in comment. Remove incorrect comment.
4331 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4332 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4333 error in drawing background.
4334 (toggleFullScreen:): Remove comment. Rearrange calls.
4335 Set toolbar values to zero, save old height in tobar_height.
4336 Restore tool bar height when leaving fullscreen.
4337 (canBecomeMainWindow): New function.
4339 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4341 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4343 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4345 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4347 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4348 that time stamps of directories could also be changed.
4349 Don't request the too broad GENERIC_WRITE, only the more restrictive
4350 FILE_WRITE_ATTRIBUTES access rights.
4352 * fileio.c (Fset_file_times): Special-case ignoring errors for
4353 directories only on MSDOS, not on MS-Windows.
4355 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4357 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4359 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4361 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4362 see whether CreateFile failed.
4364 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4366 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4367 to avoid similar races.
4368 * keyboard.c (pending_signals): Now bool, not int.
4370 Port timers to OpenBSD, plus check for timer failures.
4371 OpenBSD problem reported by Han Boetes.
4372 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4374 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4375 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4376 like OpenBSD, which has timer_settime but does not declare it.
4377 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4378 whether to use itimerspec-related primitives. All uses of
4379 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4381 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4383 * profiler.c (handle_profiler_signal): Fix a malloc race
4384 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4386 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4388 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4390 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4392 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4393 consistent with the change in return value of 'safe_strsignal'.
4395 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4397 Prefer plain 'static' to 'static inline' (Bug#12541).
4398 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4399 (bidi_set_sor_type, bidi_push_embedding_level)
4400 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4401 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4402 (bidi_cache_search, bidi_cache_ensure_space)
4403 (bidi_cache_iterator_state, bidi_cache_find)
4404 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4405 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4406 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4407 Now 'static', not 'static inline'.
4409 Count overruns when profiling; change units to ns.
4410 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4411 Give extra weight to samples after overruns, to attempt to count
4412 the time more accurately.
4413 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4414 the underlying primitives nominally do ns.
4415 (Fprofiler_cpu_start): Document the change. Mention that
4416 the sampling intervals are only approximate.
4418 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4420 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4422 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4423 case for the special 0 coding-system.
4425 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4426 (Fmake_overlay): Remove redundant tests.
4427 (fix_start_end_in_overlays): Remove redundant recentering.
4429 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4431 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4432 Update dependencies.
4434 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4436 Fix a malloc race condition involving strsignal.
4437 A signal can arrive in the middle of a malloc, and Emacs's signal
4438 handler can invoke strsignal, which can invoke malloc, which is
4439 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4440 Fix it by altering the signal handler so that it does not invoke
4442 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4443 * process.c (status_message): Use const pointer, in case strsignal
4444 is #defined to safe_strsignal.
4445 * sysdep.c (sys_siglist, init_signals): Always define and
4446 initialize a substitute sys_siglist if the system does not define
4447 one, even if HAVE_STRSIGNAL.
4448 (safe_strsignal): Rename from strsignal. Always define,
4449 using sys_siglist. Return a const pointer.
4450 * syssignal.h (safe_strsignal): New decl.
4451 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4453 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4455 * w32proc.c (timer_loop): Fix code that waits for timer
4456 expiration, to avoid high CPU usage.
4458 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4460 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4461 (sweep_weak_table): Remove redundant prototypes.
4463 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4465 * emacs.c: Move the inclusion of TERM_HEADER after including
4466 windows.h on WINDOWSNT. This avoids compilation problems with
4469 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4471 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4472 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4473 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4474 as the previous version used 'void *'.
4476 * ralloc.c (ROUNDUP): Fix last change.
4477 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4480 * w32proc.c <disable_itimers>: New static flag.
4481 (init_timers): Initialize it to zero, after creating the critical
4482 sections used by the timer threads.
4483 (term_timers): Set to 1 before deleting the critical sections.
4484 (getitimer, setitimer): If disable_itimers is non-zero, return an
4485 error indication without doing anything. Reported by Fabrice
4486 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4487 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4489 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4492 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4493 term_ntproc after all the other bookkeeping, to get timers working
4494 as long as possible.
4496 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4498 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4499 Suggested by Juri Linkov in
4500 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4502 Prefer plain 'static' to 'static inline' (Bug#12541).
4503 With static functions, modern compilers inline pretty well by
4504 themselves; advice from programmers often hurts as much as it helps.
4505 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4506 this change shrinks the text size of the Emacs executable by 1.1%
4507 without affecting CPU significantly in my benchmark.
4508 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4509 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4583 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
4584 Now 'static', not 'static inline'.
4587 (bidi_copy_it): Do the whole copy with a single memcpy.
4588 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4590 Revert the FOLLOW-SYMLINKS change for file-attributes.
4591 Doing it right would require several changes to Tramp, and there's
4592 not enough time to get that tested before the freeze today.
4593 * dired.c (directory_files_internal, Ffile_attributes):
4596 * frame.c (x_report_frame_params): Port better to wider ints.
4597 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4598 or that pointers can be printed in 15 decimal digits.
4599 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4790 Profiler improvements: more-accurate timers, overflow checks.
4791 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4792 signal.h, setjmp.h. Include systime.h instead.

4801 (handle_profiler_signal): Rename from sigprof_handler_1,
4802 for consistency with other handlers. Do not check whether
4803 cpu_log is a hash-table if garbage collecting, since it

4806 for consistency with other handlers.
4807 (setup_cpu_timer): New function, with much of what used to be in
4808 Fprofiler_cpu_start. Check for out-of-range argument.
4809 Prefer timer_settime if available, and prefer
4810 thread cputime clocks, then process cputime clocks, then
4811 monotonic clocks, to the old realtime clock. Use make_timeval
4812 to round more-correctly when falling back to setitimer.
4813 (Fprofiler_cpu_start): Use it.
4814 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4815 Don't assume that passing NULL as the 2nd argument of setitimer

4821 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4822 in profiler.c, since sysdep.c now uses it.
4824 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4962 install term_ntproc as a signal handler for SIGABRT, as that
4963 should be done by the dumped Emacs.

5057 * xfns.c (Fx_show_tip) [USE_GTK]:
5058 Use bool for boolean.
5059 * gtkutil.c (xg_update_frame_menubar):
5060 * xmenu.c (update_frame_menubar):
5061 Return void, not int, since caller ignores return value.
5062 * gtkutil.c (xg_change_toolbar_position):
5065 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5067 * makefile.w32-in (BLOCKINPUT_H): Remove.

5084 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5086 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5087 fatal_error_backtrace.
5089 * w32proc.c (sys_kill): Undo last change: don't do anything when
5090 invoked to deliver SIGABRT to our own process. This is now
5091 handled by emacs_raise.
5093 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5095 * w32term.c (w32_read_socket): Remove leftover reference to
5096 interrupt_input_pending.
5098 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5100 Do not use SA_NODEFER.
5101 Problem reported by Dani Moncayo in
5102 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5104 * sysdep.c (emacs_abort): Do not reset signal handler.
5105 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5106 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5107 wanted even on POSIXish hosts, and it doesn't work on Windows.
5109 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5111 * xterm.c (x_term_init): Call fixup_locale before and after calling
5112 gtk_init (Bug#12392).
5114 2012-09-23 Chong Yidong <cyd@gnu.org>
5116 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5117 Vdynamic_library_alist.
5119 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5120 (Fgnutls_available_p): Caller changed.
5122 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5123 (Flibxml_parse_xml_region): Likewise.
5125 * dispextern.h (struct image_type): Remove arg from init function.
5127 * image.c (Finit_image_library, lookup_image_type)
5128 (define_image_type): Remove now-unneeded second arg.
5129 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5130 (init_tiff_functions, init_gif_functions, init_svg_functions):
5131 Arglist and w32_delayed_load calling convention changed.
5132 (gs_type): Remove init_gs_functions; there is no such function.
5133 (valid_image_p, make_image): Fix caller to lookup_image_type.
5135 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5137 Simplify and avoid signal-handling races (Bug#12471).
5139 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5140 Avoid recursive loop if there's a fatal error in the function itself.
5141 * atimer.c (pending_atimers):
5142 * blockinput.h: Don't include "atimer.h"; no longer needed.
5143 (interrupt_input_pending): Remove. All uses removed.
5144 pending_signals now counts both atimers and ordinary interrupts.
5145 This is less racy than having three separate pending-signal flags.
5146 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5148 Rename from their upper-case counterparts BLOCK_INPUT,
5149 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5150 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5151 This makes it easier to access volatile variables more accurately.
5152 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5153 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5154 that's more reliable if the code is buggy and sets
5155 interrupt_input_blocked to a negative value. All uses changed.
5156 * atimer.c (deliver_alarm_signal):
5157 Remove. No need to deliver this to the parent; any thread can
5158 handle this signal now. All uses replaced by underlying handler.
5159 * atimer.c (turn_on_atimers):
5160 * dispnew.c (handle_window_change_signal):
5161 * emacs.c (handle_danger_signal):
5162 * keyboard.c (kbd_buffer_get_event):
5163 Don't reestablish signal handler; not needed with sigaction.
5164 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5166 Rework to avoid unnecessary accesses to volatile variables.
5167 (UNBLOCK_INPUT_TO): Now a function.
5168 (totally_unblock_input, unblock_input): New decls.
5169 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5170 (init_data): Remove. Necessary stuff now done in init_signal.
5171 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5172 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5173 (fatal_error_code): Remove; no longer needed.
5174 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5175 it doesn't always backtrace. All uses changed. No need to reset
5176 signal to default, since sigaction and/or die does that for us now.
5177 Use emacs_raise (FOO), not kill (getpid (), FOO).
5178 (main): Check more-accurately whether we're dumping.
5179 Move fatal-error setup to sysdep.c
5180 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5181 * gtkutil.c (xg_get_file_name, xg_get_font):
5182 Remove no-longer-needed signal-mask manipulation.
5183 * keyboard.c, process.c (POLL_FOR_INPUT):
5184 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5185 * keyboard.c (read_avail_input): Remove.
5186 All uses replaced by gobble_input.
5187 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5188 (kbd_buffer_store_event_hold, gobble_input):
5189 (record_asynch_buffer_change) [USABLE_SIGIO]:
5190 (store_user_signal_events):
5191 No need to mess with signal mask.
5192 (gobble_input): If blocking input and there are terminals, simply
5193 set pending_signals to 1 and return. All hooks changed to not
5194 worry about whether input is blocked.
5195 (process_pending_signals): Clear pending_signals before processing
5196 them, in case a signal comes in while we're processing.
5197 By convention callers now test pending_signals before calling us.
5198 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5199 New functions, to support changes to blockinput.h.
5200 (handle_input_available_signal): Now extern.
5201 (reinvoke_input_signal): Remove. All uses replaced by
5203 (quit_count): Now volatile, since a signal handler uses it.
5204 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5205 All callers changed. Block SIGINT only if not already blocked.
5206 Clear sigmask reliably, even if Fsignal returns, which it can.
5207 Omit unnecessary accesses to volatile var.
5208 (quit_throw_to_read_char): No need to restore sigmask.
5209 * keyboard.c (gobble_input, handle_user_signal):
5210 * process.c (wait_reading_process_output):
5211 Call signal-handling code rather than killing ourselves.
5212 * lisp.h: Include <float.h>, for...
5213 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5214 (pending_signals): Now volatile.
5215 (syms_of_data): Now const if IEEE floating point.
5216 (handle_input_available_signal) [USABLE_SIGIO]:
5217 (terminate_due_to_signal, record_child_status_change): New decls.
5218 * process.c (create_process): Avoid disaster if memory is exhausted
5219 while we're processing a vfork, by tightening the critical section
5221 (send_process_frame, process_sent_to, handle_pipe_signal)
5222 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5224 (send_process): No need for setjmp/longjmp any more, since the
5225 SIGPIPE stuff is now gone. Instead, report an error if errno
5227 (record_child_status_change): Now extern. PID and W are now args.
5228 Return void, not bool. All callers changed.
5229 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5230 Remove. All uses removed. This bug should be fixed now in a
5232 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5233 and record the child status change directly. This avoids the
5234 need to futz with the signal mask.
5235 (process_fatal_action): Move here from emacs.c.
5236 (emacs_sigaction_flags): New function, containing
5237 much of what used to be in emacs_sigaction_init.
5238 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5239 caught by emacs, to make races less likely.
5240 (deliver_process_signal): Rename from handle_on_main_thread.
5242 (BACKTRACE_LIMIT_MAX): Now at top level.
5243 (thread_backtrace_buffer, threadback_backtrace_pointers):
5245 (deliver_thread_signal, deliver_fatal_thread_signal):
5246 New functions, for more-accurate delivery of thread-specific signals.
5247 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5248 (deliver_arith_signal): Handle in this thread, not
5249 in the main thread, since it's triggered by this thread.
5250 (maybe_fatal_sig): New function.
5251 (init_signals): New arg DUMPING so that we can be more accurate
5252 about whether we're dumping. Caller changed.
5253 Treat thread-specific signals differently from process-general signals.
5254 Block all signals while handling fatal error; that's safer.
5255 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5257 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5258 Ignore SIGPIPE unless batch.
5259 (emacs_backtrace): Output backtrace for the appropriate thread,
5260 which is not necessarily the main thread.
5261 * syssignal.h: Include <stdbool.h>.
5262 (emacs_raise): New macro.
5263 * xterm.c (x_connection_signal): Remove; no longer needed
5264 now that we use sigaction.
5265 (x_connection_closed): No need to mess with sigmask now.
5266 (x_initialize): No need to reset SIGPIPE handler here, since
5267 init_signals does this for us now.
5269 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5271 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5272 background rect may be larger (Bug#12245).
5274 2012-09-23 Chong Yidong <cyd@gnu.org>
5276 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5278 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5280 * .gdbinit: Just stop at fatal_error_backtrace.
5281 See Stefan Monnier's request in
5282 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5283 Remove no-longer-used query of system type.
5285 2012-09-22 Chong Yidong <cyd@gnu.org>
5287 * search.c (Freplace_match): Doc fix (Bug#12325).
5289 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5291 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5292 (Fline_end_position): Doc fix.
5294 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5296 2012-09-22 Chong Yidong <cyd@gnu.org>
5298 * dispextern.h (struct image_type): Add new slot, storing a type
5299 initialization function.
5301 * image.c (define_image_type): Call the image initializer function
5302 if it is defined. Arguments and return value changed.
5303 (valid_image_p, make_image): Callers changed.
5304 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5305 (gif_type, imagemagick_type, svg_type, gs_type):
5306 Add initialization functions.
5307 (Finit_image_library): Call lookup_image_type.
5308 (CHECK_LIB_AVAILABLE): Macro deleted.
5309 (lookup_image_type): Call define_image_type here, rather than via
5310 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5311 (syms_of_image): Move define_image_type calls for xbm_type and
5312 pbm_type to lookup_image_type.
5314 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5316 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5317 'idle_timers' from here ...
5318 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5319 lists, to avoid infloops when the timer does something stupid,
5320 like reinvoke itself with the same or smaller time-out.
5323 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5325 * window.c (Fsplit_window_internal): Handle only Qt value of
5326 Vwindow_combination_limit separately.
5327 (Qtemp_buffer_resize): New symbol.
5328 (Vwindow_combination_limit): New default value.
5331 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5333 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5334 the new overlay string. (Bug#10159)
5336 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5338 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5339 or that fprintf is async-signal-safe. POSIX doesn't require
5342 2012-09-22 Chong Yidong <cyd@gnu.org>
5344 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5347 2012-09-22 Kenichi Handa <handa@gnu.org>
5349 * composite.c (composition_reseat_it): Handle the case that a
5350 grapheme cluster is not covered by a single font (Bug#12352).
5352 2012-09-21 Chong Yidong <cyd@gnu.org>
5354 * image.c (define_image_type): Avoid adding duplicate types to
5355 image_types (Bug#12463). Suggested by Jörg Walter.
5357 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5359 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5360 (print_load_command_name): Add case LC_DATA_IN_CODE.
5361 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5363 2012-09-21 Glenn Morris <rgm@gnu.org>
5365 * eval.c (Frun_hook_with_args_until_success)
5366 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5368 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5370 * fileio.c (Ffile_selinux_context): Only call freecon when
5371 lgetfilecon succeeded.
5372 (Fset_file_selinux_context): Likewise. (Bug#12444)
5374 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5376 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5377 reordering, locate the cursor by calling set_cursor_from_row; if
5378 that fails, clear the desired glyph matrix before returning a
5379 failure indication to the caller. Fixes leaving garbled display
5380 when fast scrolling with a down-key. (Bug#12403)
5381 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5382 scrolling through multibyte text.
5384 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5386 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5387 calling mark_vectorlike since that's the one that marks the window.
5388 (mark_discard_killed_buffers): Mark the final cdr.
5389 * window.h (struct window): Move prev/next_buffers to the
5390 non-standard fields.
5391 * window.c (make_window): Initialize prev/next_buffers manually.
5393 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5395 Omit unused arg EXPECTED from socket hooks.
5396 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5397 * nsterm.m (ns_term_init):
5398 * termhooks.h (struct terminal.read_socket_hook):
5399 * w32inevt.c (w32_console_read_socket):
5400 * w32term.c (w32_read_socket):
5401 * xterm.c (XTread_socket):
5402 Omit unused arg EXPECTED. All callers changed.
5403 (store_user_signal_events): Return void, not int, since callers no
5404 longer care about the return value. All uses changed.
5406 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5408 * w32gui.h (XParseGeometry): Do not declare.
5410 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5412 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5413 Ignore 'expected'. See Eli Zaretskii in
5414 <http://bugs.gnu.org/12471#8> (last line).
5416 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5417 (XParseGeometry): Now static. Substitute extremal values for
5418 values that are out of range.
5420 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5422 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5424 * nsfns.m (XParseGeometry): Remove.
5425 (Fx_create_frame): Call x_set_offset to correctly interpret
5426 top_pos in geometry.
5428 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5429 (Fx_parse_geometry): If there is a space in string, call
5430 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5432 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5434 * search.c (scan_buffer): Use character positions in calls to
5435 region_cache_forward and region_cache_backward, not byte
5436 positions. (Bug#12196)
5438 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5439 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5441 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5442 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5443 emacs_blocked_malloc, now deleted.
5445 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5447 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5448 The workaround was for improving performance on Solaris 2.4, but
5449 is getting in the way now. Emacs will still work if someone is
5450 still running Solaris 2.4 in a museum somewhere; Sun dropped
5451 support for Solaris 2.4 in 2003.
5452 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5453 * process.c (create_process) [HAVE_WORKING_VFORK]:
5454 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5455 since Emacs no longer uses vfork on that platform.
5457 2012-09-17 Glenn Morris <rgm@gnu.org>
5459 * emacs.c: Use COPYRIGHT.
5461 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5463 Remove configure's --without-sync-input option (Bug#12450).
5464 When auditing signal-handling in preparation for cleaning it up,
5465 I found that SYNC_INPUT has race conditions and would be a real
5466 pain to fix. Since it's an undocumented and deprecated
5467 configure-time option, now seems like a good time to remove it.
5468 Also see <http://bugs.gnu.org/11080#16>.
5469 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5470 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5471 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5472 (malloc_hysteresis):
5473 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5474 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5475 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5476 (dont_register_blocks, bytes_used_when_reconsidered)
5477 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5478 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5479 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5480 Remove. All uses removed.
5481 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5482 implementation, one that depends on whether the new macro
5483 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5485 * atimer.c (run_timers, handle_alarm_signal):
5486 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5487 (handle_async_input, process_pending_signals)

5496 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5497 * eval.c (handling_signal): Remove. All uses removed.
5498 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5499 All uses replaced with the SYNC_INPUT version.
5500 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5502 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5505 * font.c (Ffont_shape_gstring): Remove unused local.
5507 2012-09-16 Glenn Morris <rgm@gnu.org>
5509 * Makefile.in (clean): No longer run nextstep's clean.
5511 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5513 (ns-app): Move here from ns.mk, and simplify.
5514 (clean): Simplify nextstep entry.
5515 * ns.mk: Remove file.
5517 2012-09-17 Kenichi Handa <handa@gnu.org>
5519 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5520 not covert the last few charactes.
5522 2012-09-16 Kenichi Handa <handa@gnu.org>
5524 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5525 here, but just check the validity of glyphs in the glyph-string.
5527 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5529 * window.c (Fwindow_parameter, Fset_window_parameter):
5530 Accept any window as argument (Bug#12452).
5532 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5534 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5535 to ns_term_init to avoid memory leak.
5537 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5538 explicit retain/release.
5539 (ns_term_init): Only allow one display. Initialize outerpool and
5542 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5544 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5545 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5546 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5547 the Microsoft problem in a different way, by altering ../nt/config.nt.
5549 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5564 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5565 by lisp.h. This completes removal of setjmp.h inclusion
5566 erroneously announced in the previous commit. (Bug#12446)
5568 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5571 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5572 not defined as a macro. The latter happens on MS-Windows.
5575 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5577 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5578 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5579 Some instances of '#include <setjmp.h>' removed, if the
5580 only reason for the instance was because "lisp.h" was included.
5581 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5582 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5583 and _longjmp with the new symbols. Emacs already uses _setjmp if
5584 available, so this change affects only POSIXish hosts that have
5585 sigsetjmp but not _setjmp, such as some versions of Solaris and
5586 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5587 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5588 (png_load_body) [HAVE_PNG]:
5589 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5590 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5591 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5592 since PNG requires jmp_buf. This is the only exception to the
5593 general rule that we now use sys_setjmp and sys_longjmp.
5594 This exception is OK since this code does not change the signal
5595 mask or longjmp out of a signal handler.
5597 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5599 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5600 Include "syssignal.h", for 'main_thread'.
5602 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5604 Avoid out-of-range marker position (Bug#12426).
5605 * insdel.c (replace_range, replace_range_2):
5606 Adjust markers before overlays, as suggested by comments.
5607 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5608 Remove redundant check before calling offset_intervals.
5610 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5612 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5613 current buffer (Bug#12387).
5615 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5617 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5619 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5621 Use a more backwards-compatible timer format (Bug#12430).
5622 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5623 vector element, not from the 4th, since PSECS is now at the end.
5624 (Fcurrent_idle_time): Doc fix.
5626 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5628 Function to mark objects and remove killed buffers at once.
5629 * alloc.c (discard_killed_buffers): Rename to ...
5630 (mark_discard_killed buffers) ... new name. Add marking
5631 of remaining objects. Fix comment. Adjust users.
5632 (mark_object): Do not touch frame buffer lists here.
5633 * frame.c (delete_frame): Reset frame buffer lists here.
5635 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5637 Better workaround for GNOME bug when --enable-gcc-warnings.
5638 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5639 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5640 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5642 Simplify SIGIO usage (Bug#12408).
5643 The code that dealt with SIGIO was crufty and confusing, e.g., it
5644 played tricks like "#undef SIGIO" but these tricks were not used
5645 consistently. Simplify mostly by not #undeffing standard symbols,
5646 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5647 or not as we please) rather than "defined SIGIO" (standard symbol
5648 that we probably shouldn't #undef).
5649 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5650 Modules that need it can include it.
5651 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5652 * dispextern.h (ignore_sigio): New decl.
5653 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5654 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5655 * emacs.c (shut_down_emacs):
5656 * keyboard.c (kbd_buffer_store_event_hold):
5657 Use ignore_sigio rather than invoking 'signal' directly.
5658 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5660 (FIONREAD, SIGIO): Do not #undef.
5661 (tty_read_avail_input): Use #error rather than a syntax error.
5662 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5663 for I_PIPE, used by SETUP_SLAVE_PTY.
5664 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5665 * sysdep.c (croak): Remove; no longer needed. This bit of
5666 temporary code, with Fred N. Fish's comment that it's temporary,
5667 has been in Emacs since at least 1992!
5668 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5669 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5670 * syssignal.h (croak): Remove decl.
5671 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5672 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5673 now that we're termios-only.
5674 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5675 * term.c (dissociate_if_controlling_tty): Use #error rather than
5678 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5679 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5680 to work around GNOME bug 683906.
5681 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5682 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5683 This works around GCC bug 54561.
5685 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5687 More fixes for 'volatile' and setjmp/longjmp.
5688 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5689 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5690 (png_load_body) [HAVE_PNG]:
5691 (jpeg_load_body) [HAVE_JPEG]:
5692 New function, with most of the old parent function's body.
5693 (png_load) [HAVE_PNG]:
5694 (jpeg_load) [HAVE_JPEG]:
5695 Invoke the new function, to avoid longjmp munging our locals.
5696 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5697 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5698 longjmp is passed 2, as the C standard doesn't guarantee this.
5699 Instead, store the failure code into mgr->failure_code.
5701 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5703 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5704 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5705 (syms_of_keyboard): Remove support for unread-command-char.
5707 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5709 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5710 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5711 violation. (Bug#12426)
5713 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5715 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5717 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5719 * eval.c: Add `inhibit-debugger'.
5720 (Qinhibit_debugger): New symbol.
5721 (call_debugger): Bind it instead of Qdebug_on_error.
5722 (maybe_call_debugger): Test Vinhibit_debugger.
5723 (syms_of_eval): Define inhibit-debugger.
5724 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5725 (syms_of_xdisp): Remove inhibit-debug-on-message.
5727 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5729 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5730 If a nonvolatile local variable is written before a _longjmp to
5731 the frame containing the variable, and is read after the _longjmp,
5732 the value read is indeterminate. Some local variables of type
5733 'struct handler' and 'struct catchtag' are used in this way, so
5734 mark each of their slots as volatile if the slot can be set before
5735 _longjmp and read afterwards.
5736 * lisp.h (struct handler): var and chosen_clause are now volatile.
5737 (struct catchtag): val, next, and pdlcount are now volatile.
5739 * bidi.c (bidi_push_it, bidi_pop_it):
5740 * fns.c (copy_hash_table):
5741 * image.c (define_image_type):
5742 * keyboard.c (kbd_buffer_store_event_hold):
5743 * process.c (Fprocess_send_eof):
5744 * xfaces.c (x_create_gc) [HAVE_NS]:
5745 * xgselect.c (xg_select):
5746 Prefer assignment to memcpy when either will do.
5748 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5749 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5750 time an item is removed. No need to mark this function 'inline';
5751 the compiler knows better than we do.
5753 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5755 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5756 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5757 to change_frame_size (Bug#12388).
5758 (windowDidResize:): Pass YES to updateFrameSize.
5760 * nsterm.h: Add delay parameter to updateFrameSize.
5762 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5764 Discard killed buffers from deleted window and frame objects.
5765 This reduces an amount of references to killed buffers and
5766 helps GC to reclaim them faster.
5767 * alloc.c (discard_killed_buffers): New function.
5768 (mark_object): Use it for deleted windows and frames.
5769 (mark_object): If symbol's value is set up for a killed buffer
5770 or deleted frame, restore its global binding.
5771 * data.c (swap_in_global_binding): Add GC notice.
5772 (swap_in_symval_forwarding): Use convenient set_blv_where.
5773 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5774 * window.h: ... to here.
5776 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5778 Convenient macro to check whether the buffer is live.
5779 * buffer.h (BUFFER_LIVE_P): New macro.
5780 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5781 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5783 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5785 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5786 composition cases (Bug#12364).
5788 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5789 overhang of succeeding glyphs overlapping box cursor.
5791 * w32term.c (x_draw_glyph_string): Likewise.
5793 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5795 Simplify, document, and port floating-point (Bug#12381).
5796 The porting part of this patch fixes bugs on non-IEEE platforms
5797 with frexp, ldexp, logb.
5798 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5800 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5801 support, by removing commented-out code and briefly listing the
5802 C89 functions excluded. The commented-out stuff was confusing
5803 maintenance, e.g., we thought we needed cbrt but it was commented out.
5804 (logb): Remove decl; no longer needed.
5805 (isfinite): New macro, if not already supplied.
5806 (isnan): Don't replace any existing macro.
5807 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5808 are present on all C89 platforms.
5809 (Ffrexp): Do not special-case zero, as frexp does the right thing
5811 (Flogb): Do not use logb, as it doesn't have the desired meaning
5812 on hosts that use non-base-2 floating point. Instead, stick with
5813 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5814 frexp, to avoid getting an unspecified result.
5816 * xdisp.c (Qinhibit_debug_on_message): Now static.
5818 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5820 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5821 NSBezierPath (Bug#12131).
5823 2012-09-10 Chong Yidong <cyd@gnu.org>
5825 * fns.c (Fdelq, Fdelete): Doc fix.
5827 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5829 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5830 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5832 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5834 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5835 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5838 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5840 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5841 left fringe if the window has a left margin. This avoids leaving
5842 traces of the cursor because its leftmost pixel is not drawn over.
5844 * dispnew.c (update_window_line): When the left margin area of a
5845 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5846 that screen line. (Bug#12277)
5848 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5850 Assume C89 or later for math functions (Bug#12381).
5851 This simplifies the code, and makes it a bit smaller and faster,
5852 and (most important) makes it easier to clean up signal handling
5853 since we can stop worring about floating-point exceptions in
5854 library code. That was a problem before C89, but the problem
5855 went away many years ago on all practical Emacs targets.
5856 * data.c, image.c, lread.c, print.c:
5857 Don't include <math.h>; no longer needed.
5858 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5859 might be autoconfigured, as that never happens.
5861 * doprnt.c (DBL_MAX_10_EXP):
5862 * print.c (DBL_DIG):
5863 Remove. C89 or later always defines these.
5864 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5865 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5866 (arith_error, domain_error, domain_error2):
5867 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5868 no longer needed -- we simply return what C returns. All uses removed.
5869 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5871 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5872 Remove. All uses expanded, as these macros are no longer used
5873 more than once and are now more trouble than they're worth.
5874 (Ftan): Use tan, not sin / cos.
5875 (Flogb): Assume C89 frexp.
5876 (fmod_float): Assume C89 fmod.
5877 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5878 (init_floatfns): Remove. All uses removed.
5880 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5882 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5883 compositeToPoint for OSX < 10.6 (Bug#12390).
5885 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5887 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5888 This produces more-accurate results.
5890 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5892 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5893 changes (Bug#12088).
5895 2012-09-08 Chong Yidong <cyd@gnu.org>
5897 * syntax.c (Fstring_to_syntax): Doc fix.
5899 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5901 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5902 in the internal border.
5903 (x_set_window_size): Remove static variables and their usage.
5904 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5905 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5906 Remove fringe/internal border adjustment (Bug#11052).
5907 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5908 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5909 (ns_fix_rect_ibw): Remove.
5910 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5911 (ns_dumpglyphs_box_or_relief): Ditto.
5912 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5914 (ns_dumpglyphs_image): Ditto.
5915 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5917 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5918 their usage. Add fringe_extended_p and its use as in other terms.
5919 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5920 scroll bar was removed.
5921 (updateFrameSize): New function.
5922 (windowDidResize): Move code to updateFrameSize and call it.
5924 * nsterm.h (EmacsView): Add updateFrameSize.
5926 2012-09-07 Chong Yidong <cyd@gnu.org>
5928 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5930 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5932 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5934 More signal-handler cleanup (Bug#12327).
5935 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5936 Problem introduced when merging patches. Noted by Eli Zaretskii in
5937 <http://bugs.gnu.org/12327#67>.
5938 * floatfns.c: Comment fix.
5939 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5940 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5941 and anyway the declaration is harmless even if SIGDANGER is not defined.
5942 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5943 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5944 source files not surprisingly expected syssignal.h to define, or
5945 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5946 Include <sys/ioctl.h>, for FIONREAD.
5947 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5948 This eliminates a problem whereby other files mysteriously had
5949 to include "syssignal.h" before including "systty.h" if they
5950 wanted to use "#ifdef SIGIO".
5952 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5954 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5956 * w32.c (sigemptyset): Empty the set.
5957 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5959 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5961 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5963 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5964 (mark_object): Likewise for frame objects.
5966 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5968 * syssignal.h (handle_on_main_thread): Always declare,
5969 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5970 This ports to platforms without HAVE_PTHREAD.
5972 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5974 Signal-handler cleanup (Bug#12327).
5975 Emacs's signal handlers were written in the old 4.2BSD style with
5976 sigblock and sigmask and so forth, and this led to some
5977 inefficiencies and confusion. Rewrite these to use
5978 pthread_sigmask etc. without copying signal sets around. Also,
5979 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5980 'signal', and instead use functions that do not attempt to take
5981 over the system name space. This patch causes Emacs's text
5982 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5983 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5984 Do not include <signal.h> or "syssignal.h", as these
5985 modules do not use signals.
5986 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5987 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5988 Do not include <signal.h>, as "syssignal.h" does that for us now.
5989 * atimer.c (sigmask_atimers): New function.
5990 (block_atimers, unblock_atimers): New functions,
5991 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5993 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5994 no longer needed here.
5995 * emacs.c (main): Inspect existing signal handler with sigaction,
5996 so that there's no need to block and unblock SIGHUP.
5997 * sysdep.c (struct save_signal): New member 'action', replacing
5998 old member 'handler'.
5999 (save_signal_handlers, restore_signal_handlers):
6000 Use sigaction instead of 'signal' to save and restore.
6001 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6002 New function. All users of 'signal' modified to use set_sighandler
6003 if they're writeonly, and to use sys_signal if they're read+write.
6004 (emacs_sigaction_init, forwarded_signal): New functions.
6005 (sys_signal): Remove. All uses replaced by calls to sigaction
6006 and emacs_sigaction_init, or by direct calls to 'signal'.
6007 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6008 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6009 all uses replaced by pthread_sigmask etc. calls.
6010 * syssignal.h: Include <signal.h>.
6011 (emacs_sigaction_init, forwarded_signal): New decls.
6012 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6013 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6014 (sigmask, sys_sigmask): Remove; no longer needed.
6015 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6016 (sigblock, sigunblock, sigfree):
6017 (sigsetmask) [!defined sigsetmask]:
6018 Remove. All uses replaced by pthread_sigmask.
6019 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6020 no longer need to be replaced, and its typical old uses
6021 are now done via emacs_sigaction_init and sigaction.
6022 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6023 (sys_sigdel): Remove; unused.
6024 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6026 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6028 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6029 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6031 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6033 Explicitly mark buffer_defaults and buffer_local_symbols.
6034 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6035 mark_local_symbols here.
6036 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6037 since special buffers aren't marked here any more.
6038 (allocate_buffer): Chain new buffer with all_buffers here...
6039 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6041 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6042 (syms_of_buffer): Remove staticpro of the above.
6043 (init_buffer_once): Set names for buffer_defaults and
6044 buffer_local_symbols.
6046 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6048 Use bool for booleans in font-related modules.
6049 * font.c (font_intern_prop, font_style_to_value)
6050 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6051 (generate_otf_features, font_check_otf_features, font_check_otf)
6052 (font_match_p, font_list_entities, font_at):
6053 * fontset.c (fontset_id_valid_p, reorder_font_vector
6054 (fontset_find_font, Fset_fontset_font)
6055 (face_suitable_for_char_p) [0]:
6056 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6057 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6058 (m17n_flt_initialized, ftfont_shape_by_flt):
6059 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6060 * nsfont.m (nsfont_draw):
6061 * w32font.c (w32font_draw):
6062 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6063 Use bool for booleans.
6064 * font.h: Adjust to above API changes.
6065 (struct font, struct font_driver, struct font_driver_list):
6066 Use bool for booleans.
6067 (struct font): Remove useless member encoding_type.
6069 * fontset.c, xftfont.c: Omit unnecessary static decls.
6071 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6073 * alloc.c (mark_object): Revert window marking code
6074 since it's unsafe for the Fset_window_configuration.
6076 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6078 Fix race conditions with signal handlers and errno (Bug#12327).
6079 Be more systematic about preserving errno whenever a signal
6080 handler returns, even if it's not in the main thread. Do this by
6081 renaming signal handlers to distinguish between signal delivery
6082 and signal handling. All uses changed.
6083 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6084 * data.c (deliver_arith_signal): Rename from arith_error.
6085 * dispnew.c (deliver_window_change_signal): Rename from
6086 window_change_signal.
6087 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6088 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6089 * keyboard.c (deliver_input_available_signal): Rename from
6090 input_available_signal.
6091 (deliver_user_signal): Rename from handle_user_signal.
6092 (deliver_interrupt_signal): Rename from interrupt_signal.
6093 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6094 (deliver_child_signal): Rename from sigchld_handler.
6095 * atimer.c (handle_alarm_signal):
6096 * data.c (handle_arith_signal):
6097 * dispnew.c (handle_window_change_signal):
6098 * emacs.c (handle_fatal_signal, handle_danger_signal):
6099 * keyboard.c (handle_input_available_signal):
6100 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6101 * process.c (handle_pipe_signal, handle_child_signal):
6102 New functions, with the actual signal-handling code taken from the
6103 original respective signal handlers, sans the sporadic attempts to
6104 preserve errno, since that's now done by handle_on_main_thread.
6105 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6106 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6107 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6109 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6110 Move initialization of main_thread to sysdep.c's init_signals.
6111 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6112 our usage, and simplifies the mainline code.
6113 (record_child_status_change): New static function, as a helper
6114 for handle_child_signal, and with most of the old child handler's
6116 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6117 (handle_child_signal): Use the above.
6118 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6119 Moved here from emacs.c.
6120 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6121 code moved here from emacs.c's main function.
6122 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6123 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6124 This lets callers save and restore errno properly.
6126 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6128 Remove redundant or unused things here and there.
6129 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6130 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6131 * editfns.c (Fcompare_buffer_substrings): Likewise.
6132 * frame.h (struct terminal, struct font_driver_list):
6133 Remove redundant declarations.
6134 * window.h (Qleft, Qright): Likewise.
6136 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6138 Do not mark objects from deleted buffers, windows and frames.
6139 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6140 (mark_object): Likewise for windows and frames.
6142 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6144 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6145 buffer_defaults and buffer_local_symbols as valid objects.
6146 Return special value to denote them.
6148 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6150 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6151 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6152 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6153 (file_name_absolute_p, Fsubstitute_in_file_name):
6154 (check_executable, check_writable, Ffile_accessible_directory_p)
6155 (Fset_file_selinux_context, Fdefault_file_modes)
6156 (Finsert_file_contents, choose_write_coding_system)
6157 (Fwrite_region, build_annotations, a_write, e_write)
6159 * filelock.c (boot_time_initialized, get_boot_time)
6160 (get_boot_time_1, lock_file_1, within_one_second):
6161 * floatfns.c (in_float):
6162 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6163 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6164 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6165 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6166 * window.c (compare_window_configurations):
6167 Use bool for booleans.
6168 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6169 (Fdefault_file_modes): Now mode_t, not int, for modes.
6170 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6171 (internal_delete_file): Now returns void, not a (boolean) int,
6172 since nobody was looking at the return value.
6173 * lisp.h, window.h: Adjust to above API changes.
6175 * xdisp.c (set_message): Simplify and reindent last change.
6177 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6179 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6181 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6183 * eval.c (call_debugger): Make the function non-static so that we
6184 can call it from set_message.
6186 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6187 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6189 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6191 Give more-useful info on a fatal error (Bug#12328).
6192 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6193 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6194 of doing the work ourselves.
6195 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6196 do most of the work.
6197 (fatal_error_backtrace): New function, taken from the guts
6198 of the old fatal_error_signal, but with a new option to output
6200 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6201 info about the signal than just its number.
6202 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6203 * sysdep.c: Include <execinfo.h>
6204 (emacs_backtrace): New function, taken partly from the previous
6205 code of the 'die' function.
6206 (emacs_abort): Call fatal_error_backtrace rather than abort.
6208 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6210 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6211 eager (load-time) macro-expansion.
6212 * lisp.mk (lisp): Add macroexp.
6214 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6216 Simplify redefinition of 'abort' (Bug#12316).
6217 Do not try to redefine the 'abort' function. Instead, redo
6218 the code so that it calls 'emacs_abort' rather than 'abort'.
6219 This removes the need for the NO_ABORT configure-time macro
6220 and makes it easier to change the abort code to do a backtrace.
6221 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6222 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6223 Remove; sysdep.c's emacs_abort now takes its place.
6224 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6225 'abort' changed to use 'emacs_abort'.
6226 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6227 (abort) [!defined abort]: Rename to ...
6228 (emacs_abort): ... new name.
6229 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6230 the place of the old 'abort' in emacs.c.
6231 * w32.c, w32fns.c (abort): Do not #undef.
6232 * w32.c (emacs_abort): Rename from w32_abort.
6234 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6236 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6237 offsets[j].dv, since the y axis of the screen coordinates points
6238 down, while the y axis of the font definition coordinates points
6239 up. This fixes display of Arabic diacritics such as KASRA and
6240 KASRATAN. (Bug#11860)
6242 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6244 Be more systematic about _setjmp vs setjmp.
6245 * alloc.c (test_setjmp, mark_stack):
6246 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6247 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6248 (png_load, my_error_exit, jpeg_load):
6249 * process.c (send_process_trap, send_process):
6250 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6251 The underscored versions are up to 30x faster on some hosts.
6252 Formerly, the code used setjmp+longjmp sometimes and
6253 _setjmp+_longjmp at other times, with no particular reason to
6254 prefer setjmp+longjmp.
6256 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6258 Fix minor problem found by static checking.
6259 * buffer.c (Fdelete_all_overlays): Return nil.
6261 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6263 * buffer.c (Fdelete_all_overlays): New function.
6265 2012-09-03 Chong Yidong <cyd@gnu.org>
6267 * gtkutil.c: Add extern decl for Qxft.
6269 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6271 * emacs.c, eval.c: Use bool for boolean.
6272 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6273 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6274 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

6279 (maybe_call_debugger, Fbacktrace):
6280 * process.c (read_process_output, exec_sentinel):
6281 Use bool for booleans.
6282 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6283 All callers changed.
6284 * eval.c (interactive_p): Omit always-true boolean argument
6285 EXCLUDE_SUBRS_P. All callers changed.
6286 * dispextern.h, lisp.h: Reflect above API changes.
6287 * firstfile.c (dummy): Use the address of 'main', whose signature
6288 won't change, instead of the address of 'initialize', whose
6289 signature just changed from int to bool.
6290 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6291 * msdos.c (fatal_error_in_progress): ... from here.
6292 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6294 (redisplay_internal, unwind_redisplay): Simply clear
6295 REDISPLAYING_P when unwinding, instead of saving its previous,
6296 always-false value and then restoring it.
6298 Clean up some extern decls.
6299 Mostly, this hoists extern decls out of .c files and into .h files.
6300 That way, we're more likely to catch errors if the interfaces change.
6301 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6302 declare xg_mark_data.
6303 * dispextern.h (x_frame_parm_handlers):
6305 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6306 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6307 (Qultra_bold, Qoblique, Qitalic):
6308 Move extern decl here from .c file.
6309 * alloc.c (xg_mark_data) [USE_GTK]:
6311 * eval.c (Qlexical_binding):
6312 * fns.c (time) [!HAVE_UNISTD_H]:

6321 * xfont.c (x_clear_errors):
6322 * xterm.c (x_frame_parm_handlers):
6323 Remove now-redundant extern decls.
6324 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6325 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6327 * xfaces.c: Remove unnecessary static decls.
6328 * xterm.c (updating_frame): Remove decl of nonexistent object.
6330 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6331 when building globals.h, as the objects that are not built on
6332 this host are not needed to compile C files on this host.
6334 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6336 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
6338 * frame.h: Add missing prototype for x_wm_set_size_hint.
6340 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6344 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6345 (Fsubstitute_command_keys):

6388 offset adjustment values separately for each cluster. (Bug#11860)
6390 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6391 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6392 about implicit conversions from integer to pointer.
6394 2012-09-01 Daniel Colascione <dancol@dancol.org>

6450 window system declarations.
6452 * frame.h: Move common functions here: set_frame_menubar,
6453 x_set_window_size, x_sync, x_get_focus_frame,
6454 x_set_mouse_position, x_set_mouse_pixel_position,
6455 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6485 the frames which are reachable from Vframe_list.
6486 * term.c (mark_ttys): Remove.
6487 (init_tty): Safely initialize 'top_frame' slot with Qnil.

6511 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6512 for GCC 4.7.1 x86-64.
6514 2012-08-30 Glenn Morris <rgm@gnu.org>
6516 * lread.c (init_lread): For out-of-tree builds, only add the
6517 source directory's site-lisp dir to the load-path if it exists,
6518 consistent with in-tree builds. (Bug#12302)
6520 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6541 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6542 Add window_closed and button_values. Add void as return value for

6754 It was meant to be temporary and it often doesn't work,
6755 because when IDX has side effects the behavior of IDX==IDX
6756 is undefined. See Stefan Monnier in
6757 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

6773 All uses and decls removed.

6821 since the 1-or-0 return value is always ignored anyway.
6822 (mmap_initialized_p):
6823 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6824 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6826 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6828 * bidi.c: Use bool for boolean.
6829 This is a bit more readable, and makes the text segment of bidi.o
6830 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6831 Presumably it's faster too.
6832 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6834 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6835 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6836 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6837 (bidi_explicit_dir_char, bidi_level_of_next_char)
6838 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6839 Use bool for booleans, instead of int.
6840 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6841 (bidi_unshelve_cache): Adjust decls to match code.
6843 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6845 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6848 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6850 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6851 * atimer.h: Include <stdbool.h>.
6853 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6855 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6856 compile time tests instead of run time tests on systems that do
6858 (FRAME_MAC_P): Remove leftover from deleted code.
6859 * frame.c (syms_of_frame): Remove leftover from deleted code.
6861 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6865 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6867 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6868 Otherwise, the compiler complains about (A?B:C) where B is void
6869 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6870 (fontset_add): Return void, for FONTSET_ADD.
6872 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6874 * alloc.c: Use bool for booleans.
6875 (gc_in_progress, abort_on_gc)
6876 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6877 (dont_register_blocks) [GC_MALLOC_CHECK]:
6878 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6879 (check_string_bytes, make_specified_string, memory_full)
6880 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6881 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6882 (mark_stack, valid_pointer_p, make_pure_string)
6883 (Fgarbage_collect, survives_gc_p, gc_sweep):
6884 Use bool for booleans, instead of int.
6885 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6886 Remove unused local.
6887 * alloc.c (PURE_POINTER_P):
6888 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6889 * editfns.c (Fformat):
6890 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6892 * fns.c (sweep_weak_table):
6893 * lisp.h (suppress_checking, push_message, survives_gc_p)
6894 (make_pure_string, gc_in_progress, abort_on_gc):
6895 * lread.c (readchar, read1):
6896 * print.c (Fprin1_to_string):
6897 * xdisp.c (push_message):
6898 Use bool for booleans affected directly or indirectly by
6901 Make recently-introduced setters macros.
6902 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6903 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6904 (set_fontset_default, set_fontset_fallback): Rename from their
6905 upper-case counterparts, and make them functions rather than macros.
6906 This is more consistent with the other recently-introduced setters.
6907 These don't need to be inline, since they're local.
6909 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6911 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6912 the loop (Bug#12247).
6914 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6916 * lisp.h (vcopy): Use memcpy rather than our own loop.
6917 This fixes a performance regression introduced by the recent
6918 addition of vcopy. This means 'vcopy' will need to be modified
6919 for a copying collector, but that's OK. Also, tighten the
6920 checking in the assertion.
6922 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6924 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6925 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6926 non-base glyph for the width of the base character, according to
6927 what x_draw_composite_glyph_string_foreground expects.
6928 Generate WADJUST value according to composition_gstring_width's
6929 expectations, to produce correct width of the composed character.
6930 Reverse the sign of the DU offset produced by ScriptPlace.
6932 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6934 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6936 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6938 Avoid direct writes to contents member of struct Lisp_Vector.
6939 * lisp.h (vcopy): New function to copy data into vector.
6940 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6941 * fns.c (Ffillarray): Use ASET.
6942 * keyboard.c (timer_check_2): Use AREF and ASET.
6943 (append_tool_bar_item, Frecent_keys): Use vcopy.
6944 * lread.c (read_vector): Use ASET.
6945 * msdos.c (Frecent_doskeys): Use vcopy.
6946 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6947 (Finternal_merge_in_global_face): Use ASET and vcopy.
6948 * xfont.c (xfont_list_pattern): Likewise.
6950 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6952 * window.c (Fwindow_point): For the selected window always return
6953 the position of its buffer's point.
6954 (Fset_window_point): For the selected window always go in its
6955 buffer to the specified position.
6957 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6959 Setter macros for fontsets.
6960 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6961 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6962 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6965 2012-08-20 Glenn Morris <rgm@gnu.org>
6967 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6968 Don't assume that `ln -f' works.
6970 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6972 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6973 and later about non-assignments with no effect. See discussion at
6974 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6977 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6979 Inline setter functions for Lisp_Objects slots of struct specbinding.
6980 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6983 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6985 * window.c (select_window): Always make selected window's buffer
6988 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6990 Use AREF and ASET for docstrings of category tables.
6991 * category.h (CATEGORY_DOCSTRING): Use AREF.
6992 (SET_CATEGORY_DOCSTRING): Use ASET.
6993 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6995 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6997 Inline setter functions for hash table members.
6998 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6999 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7000 (set_hash_key_and_value, set_hash_index, set_hash_next)
7001 (set_hash_hash): New functions.
7002 * charset.c, fns.c: Adjust users.
7004 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7006 Inline getter and setter functions for per-buffer values.
7007 * buffer.h (per_buffer_default, set_per_buffer_default)
7008 (per_buffer_value, set_per_buffer_value): New functions.
7009 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7010 * buffer.c, data.c: Adjust users.
7012 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7014 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7016 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7018 Rely on <config.h> + <unistd.h> to declare 'environ',
7019 as gnulib does this if the system doesn't.
7020 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7021 Remove declaration. MS-Windows declares it on stdlib.h which is
7022 included by conf_post.h.
7023 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7024 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7025 * vm-limit.c: Include <unistd.h>, for 'environ'.
7027 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7028 (start_of_data): Remove decl; mem-limits.h provides it.
7030 * xdisp.c (handle_invisible_prop): Make it a bit faster
7031 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7033 2012-08-19 Chong Yidong <cyd@gnu.org>
7035 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7038 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7040 * .gdbinit: Use call instead of set when calling a function in the
7043 * data.c (set_internal): Don't use set_blv_found.
7044 (Fkill_local_variable): Likewise.
7046 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7048 * nsfont.m (ns_ascii_average_width): Ensure the string
7049 ascii_printable is initialized with a null-terminated character
7050 array. Otherwise, it can contain undesired extra characters.
7052 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7054 port new setting code to Sun C 5.8 2005/10/13
7055 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7056 Return void, not Lisp_Object. Otherwise, the compiler
7057 complains about (A?B:C) where B is void and C is Lisp_Object
7058 when compiling CHAR_TABLE_SET, due to the recent change to
7059 the API of sub_char_table_set_contents.
7061 2012-08-18 Chong Yidong <cyd@gnu.org>
7063 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7064 for the string case (Bug#3874).
7066 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7068 * buffer.h (BSET): Remove (Bug#12215).

7147 are compiled into code.
7148 (tset_param_alist): New setter function.
7150 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

7219 The old version was confusing because it used the same name
7220 'parent' for two different things.
7222 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
7224 Functions to get and set Lisp_Object fields of buffer-local variables.

7233 font spec, make the font's attributes take precedence over
7234 directly-specified attributes.
7235 (merge_face_ref): Recognize :font.
7237 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
7239 Do not use memcpy for copying intervals.
7240 * intervals.c (reproduce_interval): New function.

7891 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7892 * w32.c (init_environment): Change the default values of many
7893 environment variables in dflt_envvars[] to NULL, to avoid pushing
7894 them into environment when they were not already defined.
7895 Remove the code that deletes site-lisp subdirectories from the default
7896 value of EMACSLOADPATH, as it is no longer needed.
7897 (check_windows_init_file): Now external, not static.
7898 Use Vload_path as is, without adding anything, as this function is now
7899 called when Vload_path is already set up.
7901 * w32.h (check_windows_init_file): Add prototype.
7903 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7910 installation tree, as appropriate.
7912 * callproc.c (init_callproc_1): Call decode_env_path instead of
7913 doing its equivalent by hand.

7946 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7947 Remove unnecessary pointer casts.
7948 * alloc.c (record_xmalloc): New function.
7949 * lisp.h (record_xmalloc): New decl.
7950 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7951 more like a function. This is because the pointer cast is not
7952 needed. All uses changed.
7953 * print.c (print_string, print_error_message): Avoid length recalc.
7955 Improve fix for macroexp crash with debugging (Bug#12118).
7956 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7957 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7958 not supposed to be invoked from the garbage collector.

7960 (gc_aset): New function, which is like ASET but can be
7961 used in the garbage collector.

7977 headers (most versions of MinGW w32api don't).
7978 (get_security_info, create_symbolic_link)
7979 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

7986 have the required privileges.
7987 (get_file_security_desc_by_name): Rename from

7990 with addition of handling of symlinks and support for 'lstat'.
7991 If possible, get file's attributes and security information by
7992 handle, not by name. Produce S_IFLNK bit for symlinks, when
7993 called from 'lstat'.
7994 (stat, lstat): New functions, call 'stat_worker'.
7995 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7996 symlinks when the underlying filesystem supports them.
7998 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8000 Fix macroexp crash on Windows with debugging (Bug#12118).
8001 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8002 checking subscripts; problem introduced with the recent
8003 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8004 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8005 since it's used in non-static inline functions now.
8007 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8008 Don't assume buffer size fits in 'int'. Remove unused local.

8028 * composite.c (COMPOSITE_INLINE):
8029 * dispnew.c (DISPEXTERN_INLINE):
8030 * sysdep.c (SYSTIME_INLINE):
8031 Define to EXTERN_INLINE, so that the corresponding functions
8032 are compiled into code.
8033 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8034 (INLINE_HEADER_END): New macros.
8035 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8055 hard-coding the path separator.
8057 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8059 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8060 This how ASET and AREF are supposed to work, and makes
8061 it easier to think about future improvements. See
8062 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8063 * charset.h (set_charset_attr): New function.

8555 the fix for 12036 would have avoided some of the problems noted in

8579 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8580 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8581 Adjust to changes in lisp.h and emacs.c, by using
8582 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8583 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8584 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8585 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8586 instead of gdb_valbits.
8587 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8588 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8589 instead of gdb_array_mark_flag.
8590 (xboolvector): Get size from $->size, not $->header.size.
8591 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8592 (xreload, hook-run, hookpost-run): Remove.
8593 * emacs.c: Include <verify.h>.
8594 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

8601 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8602 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8603 as constants, so they're visible to GDB.

8605 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8606 Now enum constants, not macros, so they're visible to GDB.
8607 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8608 more convenient now. All uses changed.
8609 (VALMASK) [USE_LSB_TAG]: Also define in this case.

8625 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8626 than macros. This simplifies debugging in the usual case, since
8627 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8628 and it allows expressions involving EMACS_INT casts.
8629 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8631 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8648 buffer_defaults and buffer_local_symbols (for sanity and safety).
8650 2012-07-24 Eli Zaretskii <eliz@gnu.org>

8683 Swap buffer text indirection counters in Fbuffer_swap_text.
8684 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8685 This avoids crash reported by Christoph Scholtes at
8686 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8688 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8690 * nsmenu.m (Popdown_data): New struct.

8713 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8715 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8716 as it's limited by the amount of memory, not by INT_MAX.
8718 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8720 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

9494 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9495 * nsterm.m (ns_term_init):
9496 Avoid the need for strncpy, by using build_string or
9497 make_unibyte_string directly. Use dtoastr, not snprintf.
9498 * process.c (Fmake_network_process): Diagnose service names that
9499 are too long, rather than silently truncating them or creating
9500 non-null-terminated names.
9501 (Fnetwork_interface_info): Likewise, for interface names.
9502 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9503 Prefer sprintf to strncat.

9530 Optimize pure C strings initialization.
9531 * lisp.h (make_pure_string): Fix prototype.
9532 (build_pure_c_string): New function, defined as static inline. This
9533 provides a better opportunity to optimize away calls to strlen when
9534 the function is called with compile-time constant argument.
9535 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9536 argument, adjust users accordingly. Use build_pure_c_string where
9538 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9539 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9540 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9542 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9544 Avoid calls to strlen in miscellaneous functions.
9545 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

9567 * s/gnu.h (DATA_START): Move definitions to configure.
9569 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9570 We include usg5-4-common.h, which defines them both.
9572 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9573 O_RDONLY already includes it).
9575 Stop ns builds setting the EMACSLOADPATH environment variable.
9576 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9577 Now it does not set EMACSLOADPATH, just returns the load-path string.
9578 * nsterm.h: Update accordingly.
9579 * lread.c [HAVE_NS]: Include nsterm.h.
9580 (init_lread) [HAVE_NS]: Use ns_load_path.

9583 2012-07-09 Glenn Morris <rgm@gnu.org>
9585 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9586 since the included bsd-common.h does so.
9588 Stop ns builds setting the EMACSPATH environment variable.
9589 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9590 (ns_init_paths): Do not set EMACSPATH.
9591 * nsterm.h (ns_exec_path): Add it.
9592 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9595 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9597 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9599 * process.c (wait_reading_process_output): 'waitchannels' was unset
9600 when read_kbd || !NILP (wait_for_cell); fix this.
9602 Add GCC-style 'const' attribute to functions that can use it.
9603 * character.h (char_resolve_modifier_mask):
9604 * keyboard.h (make_ctrl_char):
9605 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9614 Add decls with ATTRIBUTE_CONST.
9616 Minor improvements to make_formatted_string.
9617 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9618 where int is good enough, as vsprintf returns an int.
9619 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9621 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9623 Use make_formatted_string to avoid double length calculation.

9648 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9650 Move marker debugging code under MARKER_DEBUG.
9651 * marker.c (MARKER_DEBUG): Move marker debugging code under
9652 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9653 for bootstrap with --enable-checking (~3x slowdown reported
9654 by Juanma Barranquero <lekktu@gmail.com>).
9655 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9657 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9659 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9660 See <http://bugs.gnu.org/11825#29>.
9662 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9664 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9665 has no font, use the frame's font. (Bug#11813)
9666 (display_line): Add commentary about displaying truncation glyphs
9668 (produce_special_glyphs): Move here from term.c.
9670 * term.c (produce_special_glyphs): Move to xdisp.c.
9672 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9675 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9677 * xdisp.c (display_line): Avoid warning about implicit declaration
9680 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9682 * lisp.h: Remove empty conditional.
9684 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9686 * lread.c (load_path_check): Now static.
9688 Fix some minor --with-ns problems found by static checking.
9689 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9690 (x_set_font) [!HAVE_X_WINDOWS]:
9691 * image.c (xpm_load_image) [HAVE_NS]:
9692 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9693 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9694 Remove unused local.
9695 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9696 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9697 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9698 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9699 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9700 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9701 Fix pointer signedness problem.
9702 * xfaces.c (FRAME_X_FONT_TABLE):
9703 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9705 2012-07-07 Glenn Morris <rgm@gnu.org>
9707 * lread.c (load_path_check): New function, split from init_lread.
9708 (init_lread): Reorganize. Motivation:
9709 If EMACSLOADPATH is set, check/warn about that rather than the
9710 defaults, which we are not going to use. Hence we can remove
9711 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9712 Don't warn if site-lisp directories are missing.
9713 If not installed, start from a blank load-path, since
9714 PATH_LOADSEARCH refers to the eventual installation directories.
9716 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9718 Support truncation and continuation glyphs on GUI frames, when
9719 fringes are disabled. (Bug#11832)
9720 * xdisp.c (init_iterator): Get dimensions of truncation and
9721 continuation glyphs even if on GUI frames.
9722 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9723 or both, are absent.
9724 (start_display, move_it_in_display_line_to): Handle the case of a
9725 GUI frame without a fringe to display continuation or truncation
9727 (insert_left_trunc_glyphs): Support GUI frames: make sure
9728 truncation glyphs overwrite enough glyphs from the current line to
9729 have sufficient space in pixels.
9730 (display_line): Support truncation and continuation glyphs on GUI
9731 frames. If some spare pixels are left on the line after inserting
9732 the truncation glyphs, fill that space with a stretch glyph of a
9733 suitably computed width.
9735 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9736 produce_glyphs, to support GUI sessions.
9738 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9740 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9742 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9744 Do not require float-time's arg to fit in time_t (Bug#11825).
9745 This works better on hosts where time_t is unsigned, and where
9746 float-time is applied to the (negative) difference between two times.
9747 * editfns.c (decode_time_components): Last arg is now double *,
9748 not int *, and means to store all the result as a double, without
9749 worrying about whether the seconds part fits in time_t.
9750 All callers changed.
9751 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9752 All callers changed.
9753 (Ffloat_time): Do not fail merely because the specified time falls
9754 outside of time_t range.
9756 2012-07-07 Glenn Morris <rgm@gnu.org>
9758 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9762 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9764 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9765 Update dependencies.
9767 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9769 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9771 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

9773 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9774 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9775 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9776 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9778 * xfont.c (compare_font_names): Redo to omit the need for casts.
9780 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9782 * xfns.c (Fx_change_window_property): Doc fix.
9783 * w32fns.c (Fx_change_window_property): Doc fix.
9785 * w32fns.c (Fx_window_property): Accept the same arguments as the
9786 X Windows version. Doc fix.
9787 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9789 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9790 Eli Zaretskii <eliz@gnu.org>
9792 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9793 Windows-specific code from nt/config.nt moved here.
9794 Obsolete settings removed.
9796 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9798 * process.c: Avoid unnecessary calls to gettime.
9799 (wait_reading_process_output): Don't get the time of day
9800 when gobbling data immediately and not waiting, as there's no need
9801 for it in that case. This removes a FIXME.
9803 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9805 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9806 is defined (Bug#11768).
9808 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9810 Fix marker debugging code.
9811 * marker.c (byte_char_debug_check): Do not perform the check
9812 if buffer is not multibyte.
9813 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9814 Call byte_char_debug_check with correct arguments.
9816 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9818 Compile marker debugging code only if ENABLE_CHECKING is defined.
9819 * marker.c (byte_char_debug_check, count_markers):
9820 Use only if ENABLE_CHECKING is defined.
9821 (byte_debug_flag): Remove.
9822 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9823 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9825 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9827 Avoid code repetition in marker-related functions.
9828 * marker.c (attach_marker): New function.
9829 (Fset_marker, set_marker_restricted, set_marker_both)
9830 (set_marker_restricted_both): Use it.
9831 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9832 Consistently rename charno to charpos.
9833 (marker_position): Add eassert.
9834 (marker_byte_position): Convert to eassert.

9853 * window.c (save_window_save): Likewise.
9855 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9857 Do not use Fdelete_overlay in delete_all_overlays
9858 to avoid redundant calls to unchain_overlay.
9859 * buffer.c (drop_overlay): New function.
9860 (delete_all_overlays, Fdelete_overlay): Use it.
9861 * minibuf.c (get_minibuffer): Fix comment.
9863 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9865 Port to OpenBSD 5.1 amd64.
9866 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9867 This is needed for OpenBSD, and should be harmless on all BSD systems.
9868 Also, include <sys/sysctl.h>, as it should be available on all
9869 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9870 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9871 use p_pid member, not kp_proc.pid.
9873 2012-07-06 Glenn Morris <rgm@gnu.org>
9875 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9877 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9879 More xmalloc and related cleanup.
9880 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9881 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

9883 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
9884 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
9885 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
9886 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9887 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9888 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9890 Omit needless casts involving void * pointers and allocation.
9891 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9892 as the former is more robust if P's type is changed.
9893 Prefer xzalloc to xmalloc + memset 0.
9894 Simplify malloc-or-realloc to realloc.
9895 Don't worry about xmalloc returning a null pointer.
9896 Prefer xstrdup to xmalloc + strcpy.
9897 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9899 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9900 alloca of a constant.
9902 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9904 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9905 hscroll is larger than the line width. Fixes long and futile
9906 looping inside extend_face_to_end_of_line (on a TTY) producing
9907 glyphs that are not needed and thrown away.
9909 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9911 * marker.c (set_marker_restricted_both): Simplify by using
9914 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9916 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9918 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

9924 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9925 followed by gtk_box_set_homogeneous (Bug#11768).
9926 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9927 (update_theme_scrollbar_width, xg_create_scroll_bar):
9928 Use gtk_scrollbar_new (Bug#11768).
9929 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9930 (is_box_type): New function (Bug#11768).
9931 (xg_tool_item_stale_p): Call is_box_type.
9932 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9933 with default display (Bug#11768).

10005 * fileio.c (time_error_value): Check the right error number.
10006 Problem reported by Troels Nielsen in
10007 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10009 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10011 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10012 This should be fixed in a better way; see Eli Zaretskii in
10013 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10014 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10016 * fileio.c (time_error_value): Rename from special_mtime.
10017 The old name's problems were noted by Eli Zaretskii in
10018 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10020 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10021 This variable's comment says Emacs needs at least one GDB-visible
10022 symbol of type enum pvec_type, to work around GDB problems.
10023 The symbol's value doesn't matter.
10025 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10026 that causes compilation to fail on pre-C99 compilers.
10028 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10030 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10033 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10035 * buffer.c (init_buffer_once): Fix initialization of
10036 headers for buffer_defaults and buffer_local_symbols.
10037 Reported by Juanma Barranquero <lekktu@gmail.com>.
10039 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10041 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10042 * lisp.h (enum pvec_type): Use fewer bits.
10043 (PSEUDOVECTOR_SIZE_BITS): New constant.
10044 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10045 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10046 change in pvec_type.
10047 (PSEUDOVECTOR_TYPEP): New macro.
10048 (TYPED_PSEUDOVECTORP): Use it.
10049 * fns.c (internal_equal): Adapt code to extract pvectype.
10050 * emacs.c (gdb_pvec_type): Update type.
10051 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10052 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10053 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10054 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10055 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10056 abusing vector->header.next.nbytes.
10057 (live_vector_p): Use PVEC_TYPE.
10058 (mark_object): Adapt code to extract pvectype. Use switch.
10060 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10062 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10063 Tighten new eassert a bit.
10065 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10067 Fix compilation with --enable-gcc-warnings and -O1
10068 optimization level.
10069 * doprnt.c (doprnt): Change type of tem to int, initialize
10070 to avoid compiler warning. Add eassert.
10071 * search.c (simple_search): Initialize match_byte to avoid
10072 compiler warning. Add eassert.
10074 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10076 Avoid weird behavior with large horizontal scrolls.
10077 Without this change, for example, large hscroll values would
10078 mess up Emacs's display on Fedora 15 x86, presumably due to
10079 overflows in int calculations in the display code.
10080 Also, if buffers had long lines, Emacs would freeze.
10081 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10082 (set_window_hscroll): New function, containing the old guts of
10083 Fset_window_hscroll. Return the clipped value.
10084 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10085 This avoids the need to check against PTRDIFF_MAX.
10087 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10089 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10091 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10093 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10095 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10096 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10097 since GCC 4.4.6 issues a bogus warning for them.
10099 Fix bugs in file timestamp newness comparisons.
10100 * fileio.c (Ffile_newer_than_file_p):
10101 * lread.c (Fload): Use full timestamp resolution of files,
10102 not just the 1-second resolution, so that files that are only
10103 slightly newer still count as newer.
10104 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10105 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10107 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10109 * fileio.c: Improve handling of file time marker. (Bug#11852)
10110 (special_mtime): New function.
10111 (Finsert_file_contents, Fverify_visited_file_modtime):
10112 Use it to set special mtime values consistently.
10114 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10116 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10117 marker for non-existing file. (Bug#11852)
10119 2012-07-03 Glenn Morris <rgm@gnu.org>
10121 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10122 and did not make it into globals.h).
10124 2012-07-03 Tom Tromey <tromey@redhat.com>
10126 * window.c (Fset_window_margins, Fset_window_fringes)

10154 * dosfns.c (system_process_attributes): Remove EXFUN.
10155 * keymap.h: Remove EXFUNs.
10156 * lisp.h: Remove EXFUNs.
10157 * w32term.h: Remove EXFUNs.

10160 * xterm.h: Remove EXFUN.
10162 2012-07-03 Glenn Morris <rgm@gnu.org>
10164 * lisp.h (Frandom): Make it visible to C.
10165 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10166 buffer for invisible buffers. (Bug#1229)
10168 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10170 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10171 values which aren't power of 2.
10172 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10173 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10176 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10178 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10180 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10182 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10184 * alloc.c (allocate_vector_block): Remove redundant
10185 calls to mallopt if DOUG_LEA_MALLOC is defined.
10186 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10187 avoid calls to mallopt if zero_vector is returned.
10189 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10191 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10192 is enabled, avoid dereferencing NULL current_sblock if
10195 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10197 Cleanup basic buffer management.
10198 * buffer.h (struct buffer): Change layout to use generic vector
10199 marking code. Fix some comments. Change type of 'clip_changed'
10200 to bitfield. Remove unused #ifndef old.
10201 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10202 (GET_OVERLAYS_AT): Fix indentation.
10203 (for_each_per_buffer_object_at): New macro.
10204 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

10208 struct buffer. Fix comment.
10209 (mark_overlay): New function.

10212 (mark_object): Use it. Adjust marking of misc objects
10213 and related comments.
10215 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10217 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10218 wrapper that is not needed because the wrapped code is a no-op (zero
10219 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10220 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10222 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10224 * alloc.c (mark_buffer): Simplify. Remove prototype.
10225 (mark_object): Add comment. Reorganize marking of vector-like
10226 objects. Use CHECK_LIVE for all vector-like objects except buffers
10227 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10228 Avoid redundant calls to mark_vectorlike for bool vectors.
10230 2012-06-30 Glenn Morris <rgm@gnu.org>
10232 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10234 * epaths.in (PATH_SITELOADSEARCH): New.
10235 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10236 This is rather than relying on --enable-locallisppath elements
10237 having "site-lisp" in their names. (Bug#10208#25, 11658)
10239 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10241 * w32proc.c (sys_select): Accept and ignore one more argument.
10243 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10245 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10246 (pselect) [!MS_DOS]: Redirect to sys_select.
10248 * sysdep.c: Don't include dos.h and dosfns.h.
10250 * process.c (sys_select):
10251 * msdos.c (sys_select): Accept one more argument and ignore it.
10253 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10254 adapt data types and code to that.
10257 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10258 which clashes with the gnulib function of the same name.
10260 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10262 * font.c (font_style_to_value, font_style_symbolic)
10263 (font_prop_validate_style): Add type checks for values in
10266 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10268 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10271 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10273 * xdisp.c (try_window_id): Undo last change.
10275 * w32.c (getwd): Adjust commentary about startup_dir.
10276 (init_environment): Always call sys_access, even in non-MSVC
10277 builds. Don't chdir to the directory of the Emacs executable.
10278 This undoes code from 1997 which was justified by the need to
10279 "avoid conflicts when removing and renaming directories". But its
10280 downside was that every relative file name was being interpreted
10281 relative to the directory of the Emacs executable, which can never
10282 be TRT. In particular, it broke sys_access when called with
10283 relative file names.
10284 (sys_access): Map GetLastError to errno.
10286 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10288 * window.h (struct window): Change type of 'fringes_outside_margins'
10289 to bitfield. Fix comment. Adjust users accordingly.
10290 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10292 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10295 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10297 * gnutls.c (emacs_gnutls_handshake):
10298 Add QUIT to make the loop interruptible.
10300 2012-06-29 Glenn Morris <rgm@gnu.org>
10302 * charset.c (init_charset): Make lack of etc/charsets fatal.
10304 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10306 * editfns.c (region_limit): Fix type mismatch.
10308 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10310 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10311 undefined. Convert from xassert to eassert.
10312 * nsmenu.m: Convert from xassert to eassert.
10313 * nsterm.m: Likewise.
10315 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10317 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10319 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10321 Avoid integer overflow on scroll-left and scroll-right.
10322 * window.c (HSCROLL_MAX): New macro.
10323 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10324 overflow when requested scroll falls outside ptrdiff_t range.
10326 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10328 * window.h (struct window): Change type of 'hscroll',
10329 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10330 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10331 Adjust users accordingly.
10332 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10333 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10334 from EMACS_INT to ptrdiff_t.
10335 (make_window): Omit redundant initialization.
10337 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
10339 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
10341 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10343 * window.h (struct window): Change type of 'use_time' and
10344 'sequence_number' from Lisp_Object to int.

10352 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
10353 enabled with --enable-checking=[all,glyphs] configure option.
10354 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10355 adjust comments accordingly.

10468 * alloc.c: Remove build_string.
10469 * lisp.h: Define build_string as static inline. This provides
10470 a better opportunity to optimize away calls to strlen when the
10471 function is called with compile-time constant argument.
10472 * image.c (imagemagick_error): Convert to build_string.
10473 * w32proc.c (sys_spawnve): Likewise.

10476 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10478 Use sprintf return value instead of invoking strlen on result.
10479 In the old days this wasn't portable, since some sprintf
10480 implementations returned char *. But they died out years ago and
10481 Emacs already assumes sprintf returns int.
10482 Similarly for float_to_string.
10483 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10491 Use sprintf or float_to_string result to avoid need to call strlen.
10492 * data.c (Fnumber_to_string):
10493 Use make_unibyte_string, since the string must be ASCII.
10494 * lisp.h, print.c (float_to_string): Now returns int length.
10495 * term.c (produce_glyphless_glyph):
10496 Use sprintf result rather than recomputing it.
10498 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10499 * Makefile.in (ALL_CFLAGS):

10529 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10531 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10534 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10536 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10537 instead of truncating it to 63 (admittedly a generous limit).
10539 * process.c: Fix spelling and caps in comments.

10597 * keyboard.c (kbd_buffer_get_event):
10598 * process.c (Faccept_process_output):
10599 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10600 This improves on the previous patch, which introduced a bug
10601 when time_t is unsigned and as wide as intmax_t.
10602 See <http://bugs.gnu.org/9000#51>.
10604 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10633 language ID in the event parameters.
10635 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10636 event.code, not the obscure "character set ID".
10638 2012-06-23 Chong Yidong <cyd@gnu.org>

10667 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10669 Support higher-resolution time stamps (Bug#9000).
10670 The time stamps are only nanosecond-resolution at the C level,
10671 since that's the best that any real-world system supports now.
10672 But they are picosecond-resolution at the Lisp level, as that's
10673 easy, and leaves room for future OS improvements.
10675 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10678 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10679 Don't get current time unless it's needed.
10681 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10682 now provides it if it's absent.
10683 (start_atimer): Port to higher-res time stamps.
10684 Check for time stamp overflow. Don't get current time more
10685 often than is needed.
10687 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10688 Include systime.h, not time.h.
10689 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10691 * dired.c: Include stat-time.h.
10692 (Ffile-attributes): File times now have higher resolution.
10694 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10695 (struct image): Timestamp now has higher resolution.
10697 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10698 has at least microseconds now. All uses removed.
10699 (update_frame, update_single_window, update_window, update_frame_1)
10700 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10701 (duration_to_sec_usec): Remove; no longer needed.
10703 * editfns.c (time_overflow): Now extern.
10704 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10705 (float-time, Fformat_time_string, Fcurrent_time_string)

10708 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10709 (decode_time_components, lisp_seconds_argument): New functions.
10710 (make_time): Now static.
10711 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10712 Report an error if the time is invalid, rather than having the caller
10715 * fileio.c: Include <stat-time.h>
10716 (Fcopy_file): Copy higher-resolution time stamps.
10717 Prefer to set the time stamp via a file descriptor if that works.
10718 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10719 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10720 (Fvisited_file_modtime, Fset_visited_file_modtime):
10721 Support higher-resolution time stamps.
10723 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10725 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10727 * image.c (prepare_image_for_display, clear_image_cache)
10728 (lookup_image): Port to higer-resolution time stamps.
10730 * keyboard.c (start_polling, bind_polling_period):
10731 Check for time stamp overflow.
10732 (read_char, kbd_buffer_get_event, timer_start_idle)
10733 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10734 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10735 Port to higher-resolution time stamps. Do not assume time_t is signed.
10736 (decode_timer): New function. Timers are now vectors of length 9,
10737 not 8, to accommodate the picosecond component.
10738 (timer_check_2): Use it.
10740 * nsterm.m (select_timeout, timeval_subtract): Remove.
10741 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10742 as they're a bit more accurate and handle overflow better.
10743 (ns_select): Change prototype to be compatible with pselect.
10744 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10745 * nsterm.h (ns_select): Adjust prototype.
10747 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10748 us-resolution time stamps.
10749 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10751 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10753 * lisp.h (time_overflow): New decl.
10754 (wait_reading_process_output): First arg is now intmax_t, not int,
10755 to accommodate larger waits.
10757 * process.h (struct Lisp_Process.read_output_delay):
10758 Now counts nanoseconds, not microseconds.
10759 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10761 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10762 (wait_reading_process_output):
10763 Port to ns-resolution time stamps.
10764 (Faccept_process_output, wait_reading_process_output):
10765 Check for time stamp overflow. Do not assume time_t is signed.
10766 (select_wrapper): Remove; we now use pselect.
10767 (Fprocess_attributes): Now generates ns-resolution time stamps.
10769 * sysdep.c: Include utimens.h. Don't include utime.h
10770 or worry about struct utimbuf; gnulib does that for us now.
10771 (gettimeofday): Remove; gnulib provides a substitute.
10772 (make_timeval): New function.
10773 (set_file_times): Now sets ns-resolution time stamps.
10774 New arg FD; all uses changed.
10775 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10776 (system_process_attributes):
10777 Now returns ns-resolution time stamp. All uses changed.
10778 Check for time stamp overflow.
10780 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10781 provides a substitute now.
10783 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10784 since it guarantees struct timespec.
10785 (EMACS_TIME): Now struct timespec, so that we can support
10786 ns-resolution time stamps.
10787 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10788 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10789 (EMACS_USECS): Remove.
10790 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10791 so multiply the arg by 1000 before storing it.
10792 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10794 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10795 Port to ns-resolution time stamps.
10796 (EMACS_TIME_NEG_P): Remove; replaced by....
10797 (EMACS_TIME_SIGN): New macro.
10798 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10799 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10800 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10801 (make_timeval, make_lisp_time, decode_time_components): New decls.
10802 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10803 that it mishandled time_t overflow. You can't compare by subtracting!
10804 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10805 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10807 * term.c: Include <sys/time.h>.
10808 (timeval_to_Time): New function, for proper overflow wraparound.
10809 (term_mouse_position, term_mouse_click): Use it.
10811 * undo.c (record_first_change): Support higher-resolution time stamps
10812 in the undo buffer.
10813 (Fprimitive_undo): Use them when restoring time stamps.
10815 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10816 (w32_get_internal_run_time):
10817 Port to higher-resolution Emacs time stamps.
10818 (ltime): Now accepts single 64-bit integer, as that's more convenient
10821 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10823 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10824 for compatibility with pselect. Support ns-resolution time stamps.
10826 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10828 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10829 Check for time stamp overflow, and support ns-resolution time stamps.
10831 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10832 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10833 (timeval_subtract): Remove; no longer needed.
10834 (XTflash, XTring_bell, x_wait_for_event):
10835 Port to ns-resolution time stamps. Don't assume time_t is signed.
10837 2012-06-22 Chong Yidong <cyd@gnu.org>
10839 * xdisp.c (x_consider_frame_title): Revert last change.
10841 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10843 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10844 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10845 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10846 staticidx goes up to 1597 out of 1600 = 0x640.)

11294 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11295 buffer (Bug#11226).
11297 2012-06-03 Chong Yidong <cyd@gnu.org>
11299 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
11300 (note_mode_line_or_margin_highlight): If there is no help echo,
11301 use mode-line-default-help-echo. Handle the case where the mouse
11302 position is past the end of the mode line string.
11304 * buffer.c (buffer_local_value_1): New function, split from
11305 Fbuffer_local_value; can return Qunbound.
11306 (Fbuffer_local_value): Use it.
11307 (Vmode_line_format): Docstring tweaks.
11309 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11311 * sysdep.c (system_process_attributes): Improve comment.
11313 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
11315 * keyboard.c: Export real-this-command to Elisp.
11316 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11317 and DEFVAR it. Update all users.
11319 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11321 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11323 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11324 Convert pctcpu and pctmem to Lisp float properly.
11325 Let the compiler fold better, as 100.0/0x8000 is exact.
11327 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11329 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11332 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11334 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11336 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11338 For a 'struct window', replace some Lisp_Object fields to
11339 bitfields where appropriate, remove unused fields.
11340 * window.h (struct window): Remove unused 'last_mark_x' and
11341 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11342 change its type from Lisp_Object to bitfield.
11343 Change type of 'force_start', 'optional_new_start',
11344 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11345 fields from Lisp_Object to bitfield. Adjust users accordingly.
11347 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11349 Pacify gcc -Wdouble-precision when using Xaw.
11350 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11351 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11352 Use 'float' consistently, rather than 'float' in most places
11353 and 'double' in a couple of places.
11355 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11357 * xdisp.c (handle_stop): Detect whether we have overlay strings
11358 loaded by testing it->current.overlay_string_index to be
11359 non-negative, instead of checking whether n_overlay_strings is
11360 positive. (Bug#11587)
11362 2012-05-31 Chong Yidong <cyd@gnu.org>
11364 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11366 * doc.c (Fsubstitute_command_keys): Doc fix.
11368 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11370 * search.c (search_buffer): Remove calls to
11371 r_alloc_inhibit_buffer_relocation, as it is now called by
11372 maybe_unify_char, which was the cause of relocation of buffer text
11375 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11377 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11378 for the duration of call to load_charset, to avoid problems with
11379 callers of maybe_unify_char that access buffer text through C
11382 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11383 decrement the inhibition flag, instead of just setting or
11386 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11388 Remove obsolete '#define static' cruft.
11389 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11390 This #undef was "temporary" in 2000; it is no longer needed
11391 now that '#define static' has gone away.
11392 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11393 (gray_bitmap_bits): Remove; no longer needed.
11394 All uses replaced with definiens.
11395 * xterm.c: Include "bitmaps/gray.xbm".
11397 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11399 Clean up __executable_start, monstartup when --enable-profiling.
11400 The following changes affect the code only when profiling.
11401 * dispnew.c (__executable_start): Rename from safe_bcopy.
11402 Define only on platforms that need it.
11403 * emacs.c: Include <sys/gmon.h> when profiling.
11404 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11405 (__executable_start): Remove decl, since lisp.h does it now.
11406 (safe_bcopy): Remove decl; no longer has that name.
11407 (main): Coalesce #if into single bit of code, for simplicity.
11408 Cast pointers to uintptr_t, since standard libraries want integers
11410 * lisp.h (__executable_start): New decl.
11412 2012-05-31 Glenn Morris <rgm@gnu.org>
11414 * image.c (Fimagemagick_types): Doc fix.
11416 2012-05-30 Jim Meyering <meyering@redhat.com>
11418 * callproc.c (Fcall_process_region): Include directory component
11419 in mkstemp error message (Bug#11586).
11421 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11423 * alloc.c, lisp.h (make_pure_vector): Now static.
11425 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
11427 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
11428 Move to byte-run.el.

11431 (Qdefun): Move from eval.c.
11432 * lisp.h (Qdefun): Remove.
11433 * lread.c (read1): Tiny simplification.
11435 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11437 Do not create empty overlays with the evaporate property (Bug#9642).
11438 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11439 Bug#9642, but explicitly check that the buffer the overlay would
11440 be moved to is live and rearrange lines to make sure that errors
11441 will not put the overlay in an inconsistent state.
11442 (Fdelete_overlay): Cosmetics.
11444 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11446 * w32term.c (my_bring_window_to_top): New function.
11447 (x_raise_frame): Use handle returned by DeferWindowPos, which
11448 could be different from the original one.
11449 Call my_bring_window_to_top instead of my_set_foreground_window.
11452 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11453 by calling BringWindowToTop.
11455 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

11458 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11460 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11461 This avoids undefined behavior that might cause the eassert
11462 to not catch an out-of-range value.
11464 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11466 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11467 Update dependencies.
11469 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11471 * bidi.c (bidi_mirror_char): Fix last change.
11473 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11475 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11476 when referring to sectname field in printf format.
11478 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11480 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11481 Only r_alloc_inhibit_buffer_relocation needed to be added;
11482 the others were already declared.
11484 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11485 before checking whether it's out of range. Put the check inside
11487 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11489 2012-05-27 Ken Brown <kbrown@cornell.edu>
11491 * callproc.c (Fcall_process): Restore a line that was accidentally
11492 commented out in the 2011-02-13 change (bug#11547).
11494 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11496 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11497 defined on ralloc.c.
11499 * buffer.c [REL_ALLOC]: Remove prototypes of
11500 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11501 they are now on lisp.h.
11503 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11505 * search.c (search_buffer): Use it to inhibit relocation of buffer
11506 text while re_search_2 is doing its job, because re_search_2 is
11507 passed C pointers to buffer text. (Bug#11519)
11509 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11510 Update value to 24.
11512 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11513 state after an additional call to move_it_in_display_line_to, keep
11514 the values of it->max_ascent and it->max_descent found for the
11516 (pos_visible_p): Revert the comparison against bottom_y to what it
11517 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11520 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11522 Fix coding-related core dumps with gcc -ftrapv.
11523 The code was computing A - B, where A and B are pointers, and B is
11524 random garbage. This can lead to core dumps on platforms that
11525 have special pointer registers, and it also leads to core dumps on
11526 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11527 A - B only when B is initialized properly.
11528 * coding.c (coding_set_source, coding_set_destination): Return void.
11529 (coding_change_source, coding_change_destinations): New functions,
11530 with the old behaviors of coding_set_source and coding_set_destination.
11531 All callers that need an offset changed to use these new functions.
11533 2012-05-26 Glenn Morris <rgm@gnu.org>
11535 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11537 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11539 Extend mouse support on W32 text-mode console.
11540 * xdisp.c (draw_row_with_mouse_face):
11541 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11543 * w32console.c: Include window.h.
11544 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11546 (initialize_w32_display): Initialize mouse-highlight data.
11548 * w32inevt.c: Include termchar.h and window.h.
11549 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11550 moves, call note_mouse_highlight. If help_echo changed, call
11551 gen_help_event to produce help-echo message in the echo area.
11552 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11555 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11557 * lread.c (read1): Simplify slightly to avoid an overflow warning
11558 with GCC 4.7.0 on x86-64.
11560 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11562 * bidi.c (bidi_mirror_char): Revert last change: an int is
11563 definitely wide enough here.
11565 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11567 Fix integer width and related bugs (Bug#9874).
11568 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11569 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11570 (string_bytes, check_sblock, allocate_string_data):
11571 (compact_small_strings, Fmake_bool_vector, make_string)
11572 (make_unibyte_string, make_multibyte_string)
11573 (make_string_from_bytes, make_specified_string)
11574 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11575 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11577 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11578 (allocate_pseudovector):
11579 Use int, not EMACS_INT, where int is wide enough.
11580 (inhibit_garbage_collection, Fgarbage_collect):
11581 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11582 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11583 int might not be wide enough.
11584 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11585 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11586 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11587 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11588 (bidi_level_of_next_char, bidi_move_to_visually_next):
11589 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11590 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11591 (Fkill_buffer, Fset_buffer_major_mode)
11592 (advance_to_char_boundary, Fbuffer_swap_text)
11593 (Fset_buffer_multibyte, overlays_at, overlays_in)
11594 (overlay_touches_p, struct sortvec, record_overlay_string)
11595 (overlay_strings, recenter_overlay_lists)
11596 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11597 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11598 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11599 (Foverlay_recenter, last_overlay_modification_hooks_used)
11600 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11601 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11602 (validate_region): Omit unnecessary test for b <= e,
11603 since that's guaranteed by the previous test.
11604 (adjust_overlays_for_delete): Avoid pos + length overflow.
11605 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11606 (report_overlay_modification):
11607 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11608 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11609 Omit pointer cast, which isn't needed anyway, and doesn't work
11610 after the EMACS_INT -> ptrdiff_t change.
11611 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11612 * buffer.h: Adjust decls to match defn changes elsewhere.
11613 (struct buffer_text, struct buffer):
11614 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11615 Use EMACS_INT, not int, where int might not be wide enough.
11616 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11617 not int, to avoid needless 32-bit limit on 64-bit hosts.
11618 (exec_byte_code): Use tighter memory-full test, one that checks
11619 for alloca overflow. Don't compute the address of the object just
11620 before an array, as that's not portable. Use EMACS_INT, not
11621 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11622 * callint.c (Fcall_interactively):
11623 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11624 * callproc.c (call_process_kill, Fcall_process):
11625 Don't assume pid_t fits into an Emacs fixnum.
11626 (call_process_cleanup, Fcall_process, child_setup):
11627 Don't assume pid_t fits into int.
11628 (call_process_cleanup, Fcall_process, delete_temp_file)
11629 (Fcall_process_region):
11630 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11631 (Fcall_process): Simplify handling of volatile integers.
11632 Use int, not EMACS_INT, where int will do.
11633 * casefiddle.c (casify_object, casify_region, operate_on_word)
11634 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11635 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11636 (casify_object): Avoid integer overflow when overallocating buffer.
11637 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11638 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11639 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11640 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11641 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11642 integers are now checked earlier. All uses replaced with XINT.
11644 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11645 For CCL_MapSingle, check that content and value are in int range.
11646 (ccl_driver, Fregister_code_conversion_map):
11647 Check that Vcode_version_map_vector is a vector.
11648 (resolve_symbol_ccl_program): Check that vector header is in range.
11649 Always copy the vector, so that we can check its contents reliably
11650 now rather than having to recheck each instruction as it's being
11651 executed. Check that vector words fit in 'int'.
11652 (ccl_get_compiled_code, Fregister_ccl_program)
11653 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11654 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11655 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11656 contents are in range.
11657 (Fccl_execute_on_string): Check that status is in range.
11658 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11659 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11660 Accept and return EMACS_INT, not int, because callers can pass values
11661 out of 'int' range.
11662 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11663 (multibyte_chars_in_text, parse_str_as_multibyte)
11664 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11665 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11666 (string_escape_byte8, Fget_byte):
11667 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11668 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11669 avoid mishandling large integers.
11670 * character.h: Adjust decls to match defn changes elsewhere.
11671 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11672 (Ffind_charset_region):
11673 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11674 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11675 (load_charset_map_from_vector, Fdefine_charset_internal):
11676 Don't assume fixnum fits in int.
11677 (load_charset_map_from_vector, Fmap_charset_chars):
11678 Remove now-unnecessary CHECK_NATNUMs.
11679 (Fdefine_charset_internal): Check ranges here, more carefully.
11680 Don't rely on undefined behavior with signed left shift overflow.
11681 Don't assume unsigned int fits into fixnum, or that fixnum fits
11682 into unsigned int. Don't require max_code to be a valid fixnum;
11683 that's not true for gb10830 4-byte on a 32-bit host. Allow
11684 invalid_code to be a cons, for the same reason. Require code_offset
11685 to be a character. Avoid int overflow if max_char is close
11687 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11688 this is intended anyway and avoids some undefined behavior.
11689 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11690 INDEX_TO_CODE_POINT, as that's what it expects.
11691 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11692 * charset.h (DECODE_CHAR): Return int, not unsigned;
11693 this is what was intended anyway, and it avoids undefined behavior.
11694 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11695 integer-overflow issues.
11696 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11697 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11698 where the argument is EMACS_INT, and this behavior is not intended.
11699 * chartab.c (Fmake_char_table, Fset_char_table_range)
11700 (uniprop_get_decoder, uniprop_get_encoder):
11701 Don't assume fixnum fits in int.
11702 * cmds.c (move_point): New function, that does the gist of
11703 Fforward_char and Fbackward_char, but does so while checking
11704 for integer overflow more accurately.
11705 (Fforward_char, Fbackward_char): Use it.

12382 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12384 * window.h (clip_changed): Remove useless declaration.
12386 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12388 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12389 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12391 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12394 This directory predates autoconf and is no longer needed nowadays.
12395 Move its few remaining bits of functionality to where they're needed.
12396 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12397 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12398 * m/template.h: Remove.
12399 * Makefile.in (M_FILE): Remove. All uses removed.
12400 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12401 * lisp.h (USE_LSB_TAG):
12402 * mem-limits.h (EXCEEDS_LISP_PTR):
12403 Use VAL_MAX, not VALBITS, in #if.
12404 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12405 (EMACS_UINT): Define unconditionally now.
12406 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12407 (BITS_PER_EMACS_INT): New constants, replacing
12408 what used to be in config.h, but not useful in #if.
12409 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12410 define them any more.
12411 (VAL_MAX): New macro.
12413 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12414 BITS_PER_EMACS_INT, in #if.
12415 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12416 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12417 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12418 * s/ms-w32.h (DATA_START):
12419 Move here from removed file m/intel386.h.
12420 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12421 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12423 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12425 Assume C89 or later.
12426 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12427 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12429 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12430 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12431 * textprop.c, tparam.c (NULL): Remove.
12432 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12433 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12434 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12435 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12436 * xterm.c (input_signal_count): Assume volatile works.
12438 2012-05-21 Ken Brown <kbrown@cornell.edu>
12440 * xgselect.c (xg_select): Fix first argument in call to 'select'
12443 2012-05-20 Ken Brown <kbrown@cornell.edu>
12445 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12446 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12448 2012-05-19 Ken Brown <kbrown@cornell.edu>
12450 * xfns.c (x_in_use): Remove `static' qualifier.
12451 * xterm.h (x_in_use): Declare.
12452 * xgselect.c: Include xterm.h.
12453 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12454 and `display_arg' (bug#9754).
12456 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12458 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12460 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12461 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12463 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12465 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12467 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12468 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12470 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12471 reference to image_cache->refcount.
12472 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12474 2012-05-17 Juri Linkov <juri@jurta.org>
12476 * search.c (Fword_search_regexp, Fword_search_backward)
12477 (Fword_search_forward, Fword_search_backward_lax)
12478 (Fword_search_forward_lax): Move functions to isearch.el
12479 (bug#10145, bug#11381).
12481 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12483 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12485 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12487 * lread.c (init_obarray): Declare Qt and Qnil as special.
12489 2012-05-14 Glenn Morris <rgm@gnu.org>
12491 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12492 Put "libexec" before "bin", for the sake of init_callproc_1.
12494 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12496 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12498 * unexaix.c: Port to more-recent AIX compilers.
12499 (report_error, report_error_1, make_hdr, copy_sym)
12500 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12501 Make arguments const char *, not char *, to avoid violations of C
12502 standard and to fix some AIX warnings reported by Gilles Pion.
12504 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12506 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12507 already have overlays loaded.
12508 (handle_single_display_spec): Before returning without displaying
12509 fringe bitmap, synchronize the bidi iterator with the main display
12510 iterator, by calling iterate_out_of_display_property.
12511 (iterate_out_of_display_property): Detect buffer iteration by
12512 testing that it->string is a Lisp string.
12513 (get_next_display_element): When the current object is exhausted,
12514 and there's something on it->stack, call set_iterator_to_next to
12515 proceed with what's on the stack, instead of returning zero.
12516 (set_iterator_to_next): If called at the end of a Lisp string,
12517 proceed to consider_string_end without incrementing string
12518 position. Don't increment display vector index past the end of
12519 the display vector. (Bug#11417)
12520 (pos_visible_p): Don't report a position visible when move_it_to
12521 stopped at the last line of window, which happens to be scanned
12522 backwards by the bidi iteration. (Bug#11464)
12524 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12526 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12527 and right-margin display specs even if the spec is invalid or we
12528 are on a TTY, and thus unable to display on the fringes.
12529 That's because the text with the property will not be displayed anyway,
12530 so we need to signal to the caller that this is a "replacing"
12531 display spec. This fixes display when the spec is invalid or we
12534 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12536 * unexaix.c (make_hdr): Fix typo in prototype.
12537 This bug broke the build on AIX. Problem reported by Gilles Pion.
12539 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12541 * keyboard.c (kbd_buffer_get_event): Read special events also in
12542 batch mode. (Bug#11415)
12544 2012-05-12 Glenn Morris <rgm@gnu.org>
12546 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12548 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12550 * lisp.mk (lisp): Add newcomment.elc.
12552 2012-05-12 Glenn Morris <rgm@gnu.org>
12554 * Makefile.in (MKDIR_P): New, set by configure.
12555 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12557 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12559 Remove unused function hourglass_started.
12560 * dispextern.h (hourglass_started):
12561 * w32fns.c (hourglass_started):
12562 * xdisp.c (hourglass_started): Remove.
12564 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12566 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12567 Update dependencies.
12569 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12571 * xgselect.c (xg_select): Put maxfds+1 into a var.
12572 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12574 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12576 2012-05-10 Dave Abrahams <dave@boostpro.com>
12578 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12579 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12581 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12583 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12584 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12585 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12586 Initialize xd_registered_buses.
12588 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12590 Untag more efficiently if USE_LSB_TAG.
12591 This is based on a proposal by YAMAMOTO Mitsuharu in
12592 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12593 For an admittedly artificial (nth 8000 longlist) benchmark on
12594 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12595 Emacs's overall text size by 1%.
12596 * lisp.h (XUNTAG): New macro.
12597 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12598 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12599 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12600 * eval.c (Fautoload):
12601 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12602 * frame.h (XFRAME): Use XUNTAG.
12604 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12605 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12606 Remove unportable assumptions about print widths of types like
12608 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12609 intptr_t when converting between pointer and integer, to avoid GCC
12610 warnings about wrong width.
12612 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12614 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12615 stack for each reader_thread, instead of defaulting to 8MB
12616 determined by the linker. This avoids failures in creating
12617 subprocesses on Windows 7, see the discussion in this thread:
12618 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12620 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12622 Fix up display of the *Minibuf-0* buffer in the mini window.
12623 * keyboard.c (read_char): Don't clear the echo area if there's no
12625 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12626 contents of *Minibuf-0*) if there's no message displayed in its stead.
12628 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12630 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12633 2012-05-06 Chong Yidong <cyd@gnu.org>
12635 * lisp.mk (lisp): Update.
12637 2012-05-05 Jim Meyering <meyering@redhat.com>
12639 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12641 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12643 * data.c (PUT_ERROR): New macro.
12644 (syms_of_data): Use it. Add new error type `user-error'.
12645 * undo.c (user_error): New function.
12646 (Fprimitive_undo): Use it.
12647 * print.c (print_error_message): Adjust print style for `user-error'.
12648 * keyboard.c (user_error): New function.
12649 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12651 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12653 Do not limit current-time-string to years 1000..9999.
12654 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12655 (Fcurrent_time_string): Support any year that is supported by the
12656 underlying localtime representation. Don't use asctime, as it
12657 has undefined behavior for years outside the range -999..9999.
12659 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12661 Fix race conditions involving setenv, gmtime, localtime, asctime.
12662 Without this fix, interrupts could mess up code that uses these
12663 nonreentrant functions, since setting TZ invalidates existing
12664 tm_zone or tzname values, and since most of these functions return
12665 pointers to static storage.
12666 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12667 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12668 Grow the critical sections to include not just invoking
12669 localtime/gmtime, but also accessing these functions' results
12670 including their tm_zone values if any, and any related TZ setting.
12671 (format_time_string): Last arg is now struct tm *, not struct tm **,
12672 so that the struct tm is saved in the critical section.
12673 All callers changed. Simplify allocation of initial buffer, partly
12674 motivated by the fact that memory allocation needs to be outside
12675 the critical section.
12677 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12679 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12680 with RESET_INTERVAL.
12682 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12683 Remove duplicated buffer name initialization.
12685 2012-05-02 Jim Meyering <jim@meyering.net>
12687 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12689 * xfns.c (x_window): Use xstrdup (Bug#11375).
12691 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12693 * xdisp.c (pos_visible_p): If already at a newline from the
12694 display string before the 'while' loop, don't walk back the glyphs
12695 from it3.glyph_row. Solves assertion violation when the display
12696 string begins with a newline (egg.el). (Bug#11367)
12698 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12700 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12703 2012-05-01 Glenn Morris <rgm@gnu.org>
12705 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12706 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12707 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12708 All were removed before 23.1.
12710 * dispnew.c: Remove HAVE_LIBNCURSES test;
12711 it is always true on relevant platforms.
12713 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12714 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12716 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12718 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12720 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12721 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12724 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12726 Do not avoid creating empty evaporating overlays (Bug#9642).
12727 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12728 That is, do not delete an evaporating overlay if it becomes
12729 empty after its bounds are adjusted to fit within its buffer.
12730 This fix caused other problems, and I'm reverting it until we get
12731 to the bottom of them.
12733 2012-04-27 Chong Yidong <cyd@gnu.org>
12735 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12737 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12739 * xdisp.c (pos_visible_p): If the window start position is beyond
12740 ZV, start the display from buffer beginning. Prevents assertion
12741 violation in init_iterator when the minibuffer window is scrolled
12742 via the scroll bar.
12744 * window.c (window_scroll_pixel_based): Likewise.
12746 2012-04-27 Chong Yidong <cyd@gnu.org>
12748 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12750 2012-04-27 Glenn Morris <rgm@gnu.org>
12752 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12753 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12755 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12757 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12758 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12760 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12762 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12763 display element, check also the underlying string or buffer
12764 character. (Bug#11341)
12766 * w32menu.c: Include w32heap.h.
12767 (add_menu_item): If the call to AppendMenuW (via
12768 unicode_append_menu) fails, disable Unicode menus only if we are
12769 running on Windows 9X/Me.
12771 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12773 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12774 (xgetint): Add missing shift for LSB tags.
12776 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12778 * keyboard.c (read_char): Don't wipe echo area for select window
12779 events: These might get delayed via `mouse-autoselect-window'
12782 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12784 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12785 manipulation of :loaded-from data.
12787 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12789 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12790 now a cons (bug#11311).
12792 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12794 Do not create empty overlays with the evaporate property (Bug#9642).
12795 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12796 if it becomes empty after its bounds are adjusted to fit within
12797 its buffer. Without this fix, in a nonempty buffer (let ((o
12798 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12799 yields an empty overlay that has the evaporate property, which is
12800 not supposed to happen.
12802 Fix minor GTK3 problems found by static checking.
12803 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12804 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12805 (struct _EmacsFixedClass, emacs_fixed_get_type):
12806 Move decls here from emacsgtkfixed.h, since they needn't be public.
12807 (emacs_fixed_get_type): Now static.
12808 (emacs_fixed_class_init): Omit unused local.
12809 (emacs_fixed_child_type): Remove; unused.
12810 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12811 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12812 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12813 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12814 (EMACS_FIXED_GET_CLASS): Remove; unused.
12815 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12817 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.

12911 2012-04-22 Leo Liu <sdl.web@gmail.com>
12913 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
12915 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12917 * sysdep.c [__FreeBSD__]: Minor cleanups.
12918 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12919 Use Emacs indenting style more consistently. Avoid some casts.

12945 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12946 set the status to "failed" and ensure that sentinel is run.

13003 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13004 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13005 (NEED_MEM_INSERT): New macro.
13006 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13007 Remove one incorrect comment and fix another.

13022 Remove decls. This fixes an "It stinks!".
13024 * alloc.c (which_symbols): Fix alignment issue / type clash.
13026 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13028 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13029 (struct Lisp_Misc_Any): Likewise.
13030 (struct Lisp_Free): Likewise.
13031 * alloc.c (union aligned_Lisp_Symbol): Define.

13042 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13043 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13044 * s/netbsd.h, s/sol2-6.h:
13045 Remove definition of GC_MARK_STACK, since the default now works.
13046 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13047 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13048 no longer the default.
13049 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13051 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13074 2012-04-11 Daniel Colascione <dancol@dancol.org>
13076 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13077 against is gone. It's better to use vfork now so that when Cygwin
13078 gains a new, working vfork, we use it automatically (bug#10398).
13080 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13133 * minibuf.c (Fread_variable): Callers changed.
13135 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13137 * xdisp.c (set_cursor_from_row): If the display string appears in
13138 the buffer at position that is closer to point than the position
13139 after the display string, display the cursor on the first glyph of
13140 the display string. Fixes cursor display when a 'display' text
13141 property immediately follows invisible text. (Bug#11094)
13143 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13145 composite.c: use 'double' consistently
13146 * composite.c (get_composition_id): Use 'double' consistently
13147 instead of converting 'float' to 'double' and vice versa; this is
13148 easier to understand and avoids a GCC warning.
13150 2012-04-09 Glenn Morris <rgm@gnu.org>

13197 [!WINDOWSNT]: New macros.
13198 (init_libxml2_functions, libxml2_loaded_p): New functions.
13199 (parse_region): Call fn_xmlCheckVersion instead of using the macro

13202 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13204 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13205 Call init_libxml2_functions before calling libxml2 functions.
13206 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13208 * emacs.c: Don't include libxml/parser.h.

13210 xmlCleanupParser directly.
13212 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13214 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13216 * indent.c (Fvertical_motion): If there is a display string at
13217 point, use it.vpos to compute how many lines to backtrack after
13218 move_it_to point. (Bug#11133)
13220 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13222 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13223 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13224 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13225 macros related to unification of CJK characters. For the details,
13226 see the discussion following the message here:
13227 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

13243 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13245 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13246 position we get to after a call to move_it_to fails the
13247 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13248 only if we wind up in a string from display property. (Bug#11063)
13250 * window.c (Fdelete_other_windows_internal): Invalidate the row
13251 and column information about mouse highlight, so that redisplay
13252 restores it after reallocating the glyph matrices. (Bug#7464)
13254 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13255 string comes from a `display' text property, use the buffer
13256 position of that property as if we actually saw that position in
13258 (move_it_by_lines): Remove the assertion that
13259 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13260 violated when there's a before-string at the beginning of a line.
13263 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13265 * xdisp.c (append_space_for_newline): If the default face was
13266 remapped, use the remapped face for the appended newline.
13267 (extend_face_to_end_of_line): Use the remapped default face for
13268 extending the face to the end of the line.
13269 (display_line): Call extend_face_to_end_of_line when the default
13270 face was remapped. (Bug#11068)
13272 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13274 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13276 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13278 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13280 2012-03-27 Glenn Morris <rgm@gnu.org>
13282 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13285 2012-03-26 Kenichi Handa <handa@m17n.org>
13287 * dispextern.h (struct glyph): Fix previous change. Change the
13288 bit length of glyphless.ch to 25 (Bug#11082).
13290 2012-03-26 Chong Yidong <cyd@gnu.org>
13292 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13293 (command_loop_1): Use it; inhibit selection update for
13294 handle-select-window too (Bug#8996).
13296 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13298 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13300 2012-03-25 Kenichi Handa <handa@m17n.org>
13302 * dispextern.h (struct glyph): Change the bit length of
13303 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13305 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13307 * s/ms-w32.h (tzname): Include time.h before redirecting to
13308 _tzname. Fixes the MSVC build. (Bug#9960)
13310 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13312 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13315 * xterm.c (XTread_socket): Only modify handling_signal if
13316 !SYNC_INPUT. (Bug#11080)
13318 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13320 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13321 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13322 when fetching a multibyte character consumes more bytes than
13323 CHAR_BYTES returns, due to unification of CJK characters in
13324 string_char. (Bug#11073)
13326 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13328 * process.c (wait_reading_process_output): Handle pty disconnect
13329 by refraining from sending oneself a SIGCHLD (bug#10933).
13331 2012-03-22 Chong Yidong <cyd@gnu.org>

13335 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13336 Mark string as coming from a prefix property.
13337 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13338 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13340 2012-03-21 Chong Yidong <cyd@gnu.org>
13342 * xfaces.c (Vface_remapping_alist): Doc fix.
13344 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13346 * w32proc.c (Fw32_set_console_codepage)
13347 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13350 2012-03-20 Chong Yidong <cyd@gnu.org>
13352 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13353 to reflect default non-nil value of redisplay-dont-pause.
13355 2012-03-19 Kenichi Handa <handa@m17n.org>
13357 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13358 it fit in a valid range (Bug#11003).
13360 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13362 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13363 that is not from display property, accept the row as a "cursor
13364 row" if one of the string's character has a non-nil `cursor'
13365 property. Fixes cursor positioning when there are newlines in
13366 overlay strings, e.g. in icomplete.el. (Bug#11035)
13368 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13370 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13372 2012-03-12 Chong Yidong <cyd@gnu.org>
13374 * eval.c (inhibit_lisp_code): Rename from
13375 inhibit_window_configuration_change_hook; move from window.c.
13377 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13378 * window.c (run_window_configuration_change_hook)
13379 (syms_of_window): Callers changed.

13390 is visible (Bug#10955).
13392 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13394 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

13398 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13399 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13402 2012-03-03 Glenn Morris <rgm@gnu.org>
13404 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13406 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13408 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13409 position past the first glyph_row that ends at ZV. (Bug#10902)
13410 (redisplay_window, next_element_from_string): Fix typos in
13412 (redisplay_window): Pass to move_it_vertically the margin in
13413 pixels, not in screen lines.
13415 2012-03-02 Glenn Morris <rgm@gnu.org>
13417 * buffer.c (buffer-list-update-hook): Doc fix.
13419 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13421 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13422 push_it before setting up the iterator for the first overlay
13423 string, even if we have an empty string loaded.
13424 (next_overlay_string): If there's an empty string on the iterator
13425 stack, pop the stack. (Bug#10903)
13427 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13429 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13430 Suggested by Stefan Monnier in
13431 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13432 * alloc.c (widen_to_Lisp_Object): New static function.
13433 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13434 and widening them to Lisp_Objects. This would work even if
13435 USE_LSB_TAG is defined and wide integers are used, which might
13436 happen in a future version of Emacs.
13438 2012-02-25 Chong Yidong <cyd@gnu.org>
13440 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13443 * xselect.c (Fx_selection_exists_p): Doc fix.
13444 (x_clipboard_manager_save_all): Print an informative message
13445 before saving to clipboard manager.
13447 2012-02-24 Chong Yidong <cyd@gnu.org>
13449 * keyboard.c (process_special_events): Handle all X selection
13450 requests in kbd_buffer, not just the next one (Bug#8869).
13452 2012-02-23 Chong Yidong <cyd@gnu.org>
13454 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13455 call when setting menu-bar-lines and tool-bar-lines parameters.
13456 (unwind_create_frame_1): New helper function.
13458 * window.c (inhibit_window_configuration_change_hook): New var.
13459 (run_window_configuration_change_hook): Obey it.
13460 (syms_of_window): Initialize it.

13464 * xterm.c (x_draw_image_relief): Add missing type check for
13465 Vtool_bar_button_margin (Bug#10743).
13467 2012-02-21 Chong Yidong <cyd@gnu.org>
13469 * fileio.c (Vfile_name_handler_alist): Doc fix.
13471 * buffer.c (Fget_file_buffer): Protect against invalid file
13472 handler return value.
13474 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13476 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13477 when computing $valmask.
13479 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13480 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13481 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13482 It's useless in that case, and it can cause problems on hosts
13483 that allocate halves of EMACS_INT values separately.
13484 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13485 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13486 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13487 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13488 it avoids undefined behavior on hosts where shifting right by more
13489 than the word width has undefined behavior.
13491 2012-02-19 Chong Yidong <cyd@gnu.org>
13493 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13494 (Funhandled_file_name_directory, Ffile_name_as_directory)
13495 (Fdirectory_file_name, Fexpand_file_name)
13496 (Fsubstitute_in_file_name): Protect against invalid file handler
13497 return values (Bug#10845).
13499 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13501 * .gdbinit (pitx): Fix incorrect references to fields of the

13511 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13513 2012-02-15 Chong Yidong <cyd@gnu.org>
13515 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13516 marked as special. Also, starting docstrings with * is obsolete.

13529 * keymap.c (Fsingle_key_description): Handle char ranges.
13531 2012-02-12 Chong Yidong <cyd@gnu.org>
13533 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13534 as that creates a dangerous corner case.
13536 * window.c (Fdelete_window_internal): Invalidate the mouse
13537 highlight (Bug#9904).
13539 2012-02-12 Glenn Morris <rgm@gnu.org>

13542 (Fx_get_selection_internal, Fx_disown_selection_internal)
13543 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13544 * nsselect.m (Fx_own_selection_internal)
13545 (Fx_disown_selection_internal, Fx_selection_exists_p)
13546 (Fx_selection_owner_p, Fx_get_selection_internal):
13547 Sync docs and argument specs with the xselect.c versions.
13549 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13551 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13553 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13555 * w32select.c (Fx_selection_exists_p): Sync doc string and
13556 argument list with xselect.c. (Bug#10783)

13567 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13569 2012-02-07 Chong Yidong <cyd@gnu.org>
13571 * buffer.c (Fbuffer_local_variables)
13572 (buffer_lisp_local_variables): Handle unbound vars correctly;
13573 don't let Qunbound leak into Lisp.
13575 2012-02-07 Glenn Morris <rgm@gnu.org>
13577 * image.c (Fimagemagick_types): Doc fix.
13579 * image.c (imagemagick-render-type): Change it from a lisp object
13580 to an integer. Move the doc here from the lisp manual.
13581 Treat all values not equal to 0 the same.
13583 2012-02-06 Chong Yidong <cyd@gnu.org>
13585 * doc.c (store_function_docstring): Avoid applying docstring of

13600 Include --enable-checking, if specified, in the return value.
13602 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13604 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13605 after rounding frame sizes. (Bug#9723)

13609 * keyboard.c (adjust_point_for_property): Don't position point
13610 before BEGV. (Bug#10696)
13612 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13614 Handle overflow when computing char display width (Bug#9496).
13615 * character.c (char_width): Return EMACS_INT, not int.
13616 (char_width, c_string_width): Check for overflow when
13617 computing the width; this is possible now that individual
13618 characters can have unbounded width. Problem introduced
13619 by merge from Emacs 23 on 2012-01-19.
13621 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13639 0, do not call append_composite_glyph.
13641 2012-02-02 Kenichi Handa <handa@m17n.org>
13643 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13645 (x_produce_glyphs): If the component of a composition is a null
13646 string, set it->pixel_width to 1 to avoid zero-width glyph.
13648 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13650 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13651 first 2 arguments are identical. This makes inserting large
13652 output from a subprocess an order of magnitude faster on
13653 MS-Windows, where all sbrk'ed memory is always contiguous.
13655 2012-01-31 Glenn Morris <rgm@gnu.org>

13693 2012-01-21 Chong Yidong <cyd@gnu.org>
13695 * floatfns.c (Fcopysign): Make the second argument non-optional,
13696 since nil is not allowed anyway.
13698 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13700 * process.c (read_process_output): Use p instead of XPROCESS (proc).

13707 Rewrite doc-strings.
13709 2012-01-19 Kenichi Handa <handa@m17n.org>
13711 * character.c (char_width): New function.
13712 (Fchar_width, c_string_width, lisp_string_width):
13713 Use char_width (Bug#9496).

13734 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
13735 he end column for display of highlight that ends on a newline
13738 2012-01-11 Glenn Morris <rgm@gnu.org>
13740 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

14268 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14269 Otherwise, valgrind does not work on some platforms.
14270 Problem reported by Andreas Schwab in
14271 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14272 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14273 is set, removing the need for VIRT_ADDRESS_VARIES.
14274 (PURE_P): Use a more-efficient implementation that needs just one
14275 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14276 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14277 to 4 (xorl, subq, cmpq, setbe).
14278 * alloc.c (pure): Always extern now, since that's the
14279 VIRT_ADDR_VARIES behavior.
14280 (PURE_POINTER_P): Use a single comparison, not two, for
14281 consistency with the new puresize.h.
14282 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14283 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14291 behave as if the cursor position were at the window margin.
14293 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14294 and the cursor position is out of bounds, behave as if the cursor
14295 position were at the window margin. (Bug#10075)
14297 2011-11-18 Chong Yidong <cyd@gnu.org>
14299 * window.c (Fwindow_combination_limit): Make first argument

14320 * xdisp.c (row_hash): New function, body extracted from
14321 compute_line_metrics.
14322 (compute_line_metrics): Call row_hash, instead of computing the
14325 * dispnew.c (verify_row_hash): Call row_hash for computing the
14326 hash code of a row, instead of duplicating code from xdisp.c.
14328 * dispextern.h (row_hash): Add prototype.
14330 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

14366 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14368 * xdisp.c (display_line): Move the call to
14369 highlight_trailing_whitespace before the call to
14370 compute_line_metrics, since the latter needs to see the final
14371 faces of all the glyphs to compute ROW's hash value.
14372 Fixes assertion violations in row_equal_p. (Bug#10035)
14374 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14376 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14377 just return (bug#10044).
14379 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14381 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14382 with user-defined heap size. Bump the default size of the temacs
14383 heap to 27MB, to avoid memory warning when running temacs.

14386 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14387 current_matrix and desired_matrix. (Bug#9990)
14388 (verify_row_hash) [XASSERTS]: New function.

14435 Avoid some portability problems by eschewing 'extern inline' functions.
14436 The trivial performance wins aren't worth the portability hassles; see
14437 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14439 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14442 by removing the "extern"s.
14443 * intervals.c (adjust_intervals_for_insertion)
14444 (adjust_intervals_for_deletion): Undo previous change,
14445 making these static again.

14505 * xmenu.c (cleanup_widget_value_tree): New function.
14506 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14513 (window_box_width, window_box_left, window_box_left_offset)
14514 (window_box_right, window_box_right_offset): Declare extern.
14515 Otherwise, these inline functions do not conform to C99 and
14516 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14517 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14518 * intervals.c (adjust_intervals_for_insertion)

14521 (static_offset_intervals): Remove.
14522 (offset_intervals): Rewrite using the old contents of
14523 static_offset_intervals. The old version didn't conform to C99
14524 because an extern inline function contained a reference to an
14525 identifier with static linkage.

14671 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14672 past the beginning of the current glyph matrix.
14674 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14676 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14677 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14678 HAVE_GTK3 (Bug#9869).
14680 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
14681 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14683 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14685 * xterm.c: Declare x_handle_net_wm_state to return int.
14686 (handle_one_xevent): Check if we are iconified but don't have
14687 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14688 (get_current_wm_state): Return non-zero if not hidden,
14689 check for _NET_WM_STATE_HIDDEN (Bug#9893).
14690 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
14691 (x_handle_net_wm_state): Return what get_current_wm_state returns.
14692 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
14694 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14696 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14697 so that this new function doesn't get optimized away by a
14698 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14700 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14702 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14704 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14706 Fix the `xbytecode' command.
14707 * .gdbinit (xprintbytestr): New command.
14708 (xwhichsymbols): Rename from `which'; all callers changed.
14709 (xbytecode): Print the byte-code string as well.
14711 2011-10-29 Kim Storm <storm@cua.dk>
14713 * alloc.c (which_symbols): New function.
14715 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14717 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14720 2011-10-29 Glenn Morris <rgm@gnu.org>
14722 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14723 Not clear what it was for, and it causes various bugs. (Bug#9839)
14725 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14727 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14728 possible random value that matches one of those tested as
14729 condition to clear the mouse face.
14731 2011-10-28 Chong Yidong <cyd@gnu.org>
14733 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14735 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14737 * window.c (make_window): Initialize phys_cursor_on_p.
14739 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14741 * lisp.h (struct Lisp_Symbol): Update comments.
14743 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14745 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14747 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14749 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14750 <oslsachem@gmail.com> for helping to debug this.
14752 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14753 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14754 (g_b_init_get_glyph_outline_w): New static variables.
14755 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14756 (GetGlyphOutlineW_Proc): New typedefs.
14757 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14758 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14760 (w32font_open_internal, compute_metrics):
14761 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14762 instead of calling the "wide" APIs directly.
14764 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14766 * w32.h (syms_of_w32font): Add prototype.
14768 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14770 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14771 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14772 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14773 (Fmove_to_window_line): Doc fix.
14775 2011-10-27 Chong Yidong <cyd@gnu.org>
14777 * process.c (make_process): Set gnutls_state to NULL.
14779 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14780 non-NULL, regardless of GNUTLS_INITSTAGE.
14781 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14782 an error. Set process slots as soon as we allocate them.
14784 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14786 2011-10-27 Chong Yidong <cyd@gnu.org>
14788 * gnutls.c (emacs_gnutls_deinit): New function.
14789 Deallocate credentials structures as well as calling gnutls_deinit.
14790 (Fgnutls_deinit, Fgnutls_boot): Use it.
14792 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14793 (deactivate_process): Call emacs_gnutls_deinit.
14795 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14797 * image.c (x_create_x_image_and_pixmap):
14798 * w32.c (sys_rename, w32_delayed_load):
14799 * w32font.c (fill_in_logfont):
14800 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14802 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14804 * w32fns.c (w32_default_color_map): New function,
14805 extracted from Fw32_default_color_map.
14806 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14808 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14810 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14812 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14814 * keyboard.c (test_undefined): New function (bug#9751).
14815 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14817 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14819 * sysdep.c (init_sys_modes): Fix the check for the controlling
14820 terminal (Bug#6649).
14822 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14824 * dispextern.h (struct bidi_it): New member next_en_type.
14826 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14827 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14828 current character, check also for next_en_type being WEAK_EN.
14829 (bidi_resolve_weak): Don't enter the expensive loop if the current
14830 position is before next_en_pos. Record the bidi type of the first
14831 non-ET, non-BN character we find, in addition to its position.
14832 (bidi_level_of_next_char): Invalidate next_en_type when
14833 next_en_pos is over-stepped.
14835 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14837 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14838 * editfns.c: Rewrite current-time-zone so that it invokes
14839 the equivalent of (format-time-string "%Z") to get the time zone name.
14840 This fixes a bug when the time zone name contains characters that
14841 need converting from the system time locale to Emacs internal format.
14842 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14843 that patch fixed format-time-string to do the conversion, but
14844 I forgot to fix current-time-zone.
14845 (format_time_string): New function, containing most of
14846 what Fformat_time_string used to contain.
14847 (Fformat_time_string): Rewrite in terms of format_time_string.
14848 This doesn't change this function's behavior.
14849 (current-time-zone): Rewrite to use format_time_string.
14850 This fixes the bug reported by Michael Schierl in
14851 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14852 Jason Rumney's 2007-06-07 change worked around this bug, but
14854 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14856 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14858 * xdisp.c (start_display): If the character at POS is displayed
14859 via a display vector, reset IT->current.dpvec_index to zero.
14860 (try_window_reusing_current_matrix): If a line ends in a display
14861 vector or the next line starts in a display vector, continue
14862 redrawing the window even though the character position of
14863 start_row was reached.
14866 2011-10-18 Chong Yidong <cyd@gnu.org>
14868 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14869 with nobreak-char-display too.
14871 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14873 Fix part 3 of bug#9771.
14874 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14875 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14876 non-neutral characters if the current character is a paragraph
14877 separator (a.k.a. Newline). This avoids running the same
14878 expensive loop twice, once when we consume the preceding newline
14879 and the other time when the line actually needs to be displayed.
14880 Avoid the loop when we see neutrals on the base embedding level
14881 following a character whose directionality is the same as the
14882 paragraph's. This avoids running the expensive loop when a line
14883 ends in a long sequence of neutrals, like control characters.
14884 Add assertion against STRONG_AL type. Slightly rearrange code
14885 that determines the type of a neutral given the first non-neutral
14887 (bidi_level_of_next_char): Set next_en_pos to zero when
14888 invalidating its info.
14890 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14892 * xdisp.c (push_display_prop): Determine whether to record string
14893 or buffer position by IT->string, not by IT->method. Allow
14894 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14895 (move_it_vertically_backward): Don't look for character position
14896 immediately after the newline when in a continuation line.
14899 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14901 * window.c (coordinates_in_window): Rewrite and delabelize
14902 vertical border check. (Bug#5357) (Bug#9618)
14904 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14906 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14907 errors in XSetWindowBorder (bug#9310).
14909 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14911 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14912 avoid crash when xmalloc overrun checking is enabled.
14914 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14916 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14917 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14918 cursor motion with <left> and <right> arrow keys.
14920 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14921 some callers set that themselves.
14923 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14925 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14926 display string and the previous row comes from the same string and
14927 is empty. (Bug#9739) (Bug#9738)
14929 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14931 * doc.c (get_doc_string): Encode file name (bug#9735).
14933 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14935 * bidi.c (bidi_level_of_next_char):
14936 * xdisp.c (get_visually_first_element): Remove old incorrect
14937 comments regarding the Unicode Line Separator character.
14939 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14941 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14943 * alloc.c (Fgc_status): Do not access beyond zombies array
14944 boundary if nzombies > MAX_ZOMBIES.
14945 * alloc.c (dump_zombies): Add missing format specifier.
14947 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14949 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14950 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14952 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14953 Some packages use them to denote characters with modifiers.
14955 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14957 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14958 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14959 matching a pp-number. Rename parameter var to var1.
14961 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14963 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14965 2011-10-08 Glenn Morris <rgm@gnu.org>
14967 * callint.c (Fcall_interactively): Give a more explicit error for the
14968 'c' case with a non-character input. (Bug#8479)
14970 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14972 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14974 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14975 lines that are hscrolled on the left.
14977 * dispnew.c (buffer_posn_from_coords): Account for a possible
14978 presence of header-line. (Bug#4426)
14980 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14982 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14983 Don't advertise functionality which we discourage or doesn't work.
14985 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14987 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14988 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14989 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14990 this makes Emacs dump core during garbage collection on rare
14991 occasions. sizeof is obviously inferior to offsetof here, so
14992 stick with offsetof.
14993 (GC_POINTER_ALIGNMENT): New macro.
14994 (mark_memory): Omit 3rd (offset) arg; caller changed.
14995 Don't assume EMACS_INT alignment is the same as pointer alignment.
14997 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14999 * keyboard.c (read_key_sequence_remapped): New var.
15000 (read_key_sequence): Compute remapping in the right buffer.
15001 (command_loop_1): Use read_key_sequence's remapping directly.
15003 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15005 * dired.c (file_name_completion): Don't expand file name.
15006 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15007 before checking file name handler.
15009 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15010 they've been requested explicitly (bug#9591).
15012 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15014 * keymap.c (Fsingle_key_description): Use make_specified_string
15015 instead of build_string to build string from push_key_description.
15018 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15020 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15021 This fixes a Y2038 bug on 64-bit hosts.
15022 * buffer.c (reset_buffer):
15023 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15024 (Fclear_buffer_auto_save_failure):
15025 Use 0, not -1, to represent an unset failure time, since time_t
15026 might not be signed.
15028 Remove dependency on glibc malloc internals.
15029 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15030 Move back here from lisp.h, but with their new implementations.
15031 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15032 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15033 * charset.c (charset_table_init): New static var.
15034 (syms_of_charset): Use it instead of xmalloc. This removes a
15035 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15036 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15037 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15038 Move back to alloc.c.
15039 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15040 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15042 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15044 * nsterm.m (windowDidResize): Call x_set_window_size only when
15045 ns_in_resize is true. Otherwise set pixelwidth/height and
15046 call change_frame_size (Bug#9628).
15048 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15050 Port --enable-checking=all to Fedora 14 x86-64.
15051 * charset.c (syms_of_charset): Also account for glibc malloc's
15052 internal overhead when calculating the initial malloc maximum.
15054 Port --enable-checking=all to Fedora 14 x86.
15055 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15057 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15058 (overrun_check_realloc, overrun_check_free):
15059 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15060 That way, xmalloc returns a properly-aligned pointer even if
15061 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15062 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15063 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15064 into account when calculating the initial malloc maximum.
15065 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15066 Move here from alloc.c, so that charset.c can use it too.
15067 Properly align; the old code wasn't right for common 32-bit hosts
15068 when configured with --enable-checking=all.
15069 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15070 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15072 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15074 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15077 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15079 * xdisp.c (compute_display_string_end): If there's no display
15080 string at CHARPOS, return -1.
15082 * bidi.c (bidi_fetch_char): When compute_display_string_end
15083 returns a negative value, treat the character as a normal
15084 character not covered by a display string. (Bug#9624)
15086 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15088 * lread.c (Fread_from_string): Fix typo in docstring.
15090 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15092 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15093 newline, reseat the iterator instead of bidi-iterating there one
15094 character at a time. (Bug#9610)
15095 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15096 TO_CHARPOS if the bidi iterator is at base embedding level.
15098 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15100 * lread.c (readevalloop): Use correct code for NBSP.
15101 (read1): Likewise. (Bug#9608)
15103 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15105 * dbusbind.c (Fdbus_register_signal): When service is not
15106 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15108 2011-09-25 Glenn Morris <rgm@gnu.org>
15110 * buffer.c (truncate-lines): Doc fix.
15112 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15114 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15115 (Fset_window_next_buffers): Doc fix.

15127 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15129 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15130 Default value is now t. Doc fix.
15132 * indent.c (Fvertical_motion): Compute and apply the overshoot
15133 logic when moving up, not only when moving down. Fix the
15134 confusing name and values of the it_overshoot_expected variable;
15135 logic changes accordingly. (Bug#9254) (Bug#9549)
15137 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15138 CHARPOS is covered by a display string which includes newlines.
15139 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15140 is covered by a display string with embedded newlines.
15142 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15144 * dbusbind.c (Fdbus_register_signal): Add match rule to
15145 Vdbus_registered_objects_table. (Bug#9581)
15146 (Fdbus_register_method, Vdbus_registered_objects_table):
15149 2011-09-24 Jim Meyering <meyering@redhat.com>
15151 do not ignore write error for any output size
15152 The previous change was incomplete.
15153 While it makes emacs --batch detect the vast majority of stdout
15154 write failures, errors were still ignored whenever the output size is
15155 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15156 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15157 && echo FAIL: ignored write error
15158 FAIL: ignored write error
15159 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15160 && echo FAIL: ignored write error
15161 FAIL: ignored write error
15162 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15164 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15166 * emacs.c (Fkill_emacs): In noninteractive mode exit
15167 non-successfully if a write error occurred on stdout. (Bug#9574)
15169 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15171 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15174 * dispextern.h (struct it): Update the comment documenting what
15177 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15179 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15180 a display string, extend search for cursor position to end of row.
15181 (find_row_edges): If the row ends in a newline from a display
15182 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15183 Handle the case of a display string with multiple newlines.
15184 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15185 non-empty line. Fixes confusing cursor motion with arrow keys at
15186 the beginning of a line that starts with whitespace.
15188 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15190 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15193 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15195 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15196 boolean (Bug#9154).
15198 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15200 * xdisp.c (display_line): Record maximum and minimum buffer
15201 positions even if no glyphs were produced (e.g., by a zero-width
15202 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15203 buffer positions that will be removed from the glyph row because
15205 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15206 column is beyond frame width: don't subtract 1 "pixel" when
15207 computing width of the stretch.
15208 (reseat_at_next_visible_line_start): Undo the change made on
15209 2011-09-17 that saved paragraph information and restored it after
15210 the call to `reseat'. (Bug#9545)
15212 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15214 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15215 and turn window cursor on if cleared (Bug#9415).
15217 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15219 * search.c (boyer_moore): Take unibyte characters from pattern
15220 literally. (Bug#9458)

15230 initialized, to pacify gcc -Wuninitialized.
15232 * fileio.c: Report proper errno when syscall falls.
15233 (Finsert_file_contents): Save and restore errno,
15234 so that report_file_error outputs the correct diagnostic.
15235 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15237 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15239 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15241 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15243 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15244 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15246 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15248 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15249 about the current paragraph and restore it after the call to reseat.
15251 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15252 (bidi_find_paragraph_start): Search back for paragraph beginning
15253 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15254 (bidi_move_to_visually_next): Only trigger paragraph-related
15255 computations when the last character is a newline or at EOB, not
15256 just any NEUTRAL_B. (Bug#9470)
15258 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15259 truncated lines if point is covered by a display string. (Bug#9524)
15261 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15263 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15264 (cons_to_x_long): New function.
15265 (lisp_data_to_selection_data): Use it. Correct the test for
15266 short-versus-long data; it was negated. Break out of vector
15267 loop, for efficiency, when a long datum is discovered.
15269 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15271 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15273 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15275 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15276 GCC PR/17406) by declaring this function with external scope.
15278 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15280 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15281 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15283 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15285 * editfns.c (Fformat): Correctly handle text properties on "%%".

15293 * xdisp.c (get_next_display_element)
15294 (fill_composite_glyph_string): Add comments about special meaning
15295 of TAB characters in a composition.
15297 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15299 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15300 This occurs when processing a multibyte format.
15301 Problem reported by Wolfgang Jenker.
15303 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15305 * xdisp.c (try_cursor_movement): Only check for exact match if
15306 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15308 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15310 Remove unused external symbols.
15311 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15312 * xdisp.c (calc_pixel_width_or_height): Now static.
15313 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15314 * indent.c (check_display_width):
15315 * w32term.c: Fix comment to match code.
15316 * xterm.c, xterm.h (x_catching_errors): Remove.
15318 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15320 * xselect.c: Use signed conversions more consistently (Bug#9498).
15321 (selection_data_to_lisp_data): Assume incoming selection data are
15322 signed integers, not unsigned. This is to be consistent with
15323 outgoing selection data, which was modified to use signed integers
15324 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15325 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15326 expects long, not unsigned long.
15328 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15330 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15331 computation of loop end. Reported by Johan Bockgård
15334 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15336 * frame.c (Fother_visible_frames_p): Function deleted.
15338 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15340 * indent.c (compute_motion): Process display vector front to back
15341 rather than the other way around. (Bug#2496)
15343 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15345 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15347 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15349 * minibuf.c (Fread_from_minibuffer): Doc fix.
15351 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15353 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15354 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15356 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15358 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15359 value for non-existent files.
15361 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15363 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15364 set its "size" to -1. This will set the modtime_size field of
15365 the corresponding buffer to -1, which is what
15366 verify-visited-file-modtime expects for files that do not exist.
15369 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15371 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15373 * lisp.h: ... from here. push_key_description is no longer
15374 defined in keyboard.c, so its declaration should not be in
15375 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15376 logically belongs with push_key_description.
15378 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15380 * buffer.h: Include <sys/types.h> instead of <time.h>.
15381 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15382 Problem reported by Herbert J. Skuhra.
15384 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15386 * xml.c (parse_region): Make the parsing work for
15387 non-comment-starting XML files again (bug#9144).
15389 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15391 * image.c (gif_load): Fix calculation of bottom and right corner.
15394 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15396 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15397 redisplay in small windows.
15399 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15401 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15403 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15405 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15406 Operate on live windows only.
15408 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15410 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15412 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15414 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15415 only under bidi iteration.
15417 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15419 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15421 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15423 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15424 Without this fix, the command to link temacs failed due to an
15425 undefined symbol __builtin_isnan. This is because
15426 /usr/include/iso/math_c99.h #defines isnan(x) to
15427 __builtin_isnan(x), but the bundled gcc, which identifies itself
15428 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15430 * floatfns.c (isnan): #undef, and then #define to a clone of
15432 (Fisnan): Always define, since it's always available now.
15433 (syms_of_floatfns): Always define isnan at the Lisp level.
15435 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15437 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15439 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15441 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15442 The previous code assumed that file offsets (off_t values) fit in
15443 EMACS_INT variables, which is not true on typical 32-bit hosts.
15444 The code messed up by falsely reporting buffer overflow in cases
15445 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15446 when "big" contains more than 2**29 bytes, even though this
15447 inserts just one byte and does not overflow the buffer.
15448 (Finsert_file_contents): Store file offsets as off_t
15449 values, not as EMACS_INT values. Check for overflow when
15450 converting between EMACS_INT and off_t. When checking for
15451 buffer overflow or for overlap, take the offsets into account.
15452 Don't use EMACS_INT for small values where int suffices.
15453 When checking for overlap, fix a typo: ZV was used where
15454 ZV_BYTE was intended.
15455 (Fwrite_region): Don't assume off_t fits into 'long'.
15456 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15458 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15460 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15462 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15464 sprintf-related integer and memory overflow issues (Bug#9412).
15466 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15467 (esprintf, exprintf, evxprintf): New functions.
15468 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15469 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15470 (modify_event_symbol): Do not assume that the length of
15471 name_alist_or_stem is safe to alloca and fits in int.
15472 (Fexecute_extended_command): Likewise for function name and binding.
15473 (Frecursion_depth): Wrap around reliably on integer overflow.
15474 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15475 since some callers pass EMACS_INT values.
15476 (Fsingle_key_description): Don't crash if symbol name contains more
15477 than MAX_ALLOCA bytes.
15478 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15479 (get_minibuffer): Arg is now EMACS_INT, not int.
15480 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15481 (esprintf, exprintf, evxprintf): New decls.
15482 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15484 * dbusbind.c (signature_cat): New function.
15485 (xd_signature, Fdbus_register_signal):
15486 Do not overrun buffer; instead, report string overflow.
15488 * dispnew.c (add_window_display_history): Don't overrun buffer.
15489 Truncate instead; this is OK since it's just a log.
15491 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15492 even if the time zone offset is outlandishly large.
15493 Don't mishandle offset == INT_MIN.
15495 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15496 when creating daemon; the previous buffer-overflow check was incorrect.
15498 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15499 which has the guts of the old verror function.
15501 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15502 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15504 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15505 (font_unparse_xlfd): Don't blindly alloca long strings.
15506 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15507 fits in int, when using sprintf. Use single snprintf to count
15508 length of string rather than counting it via multiple sprintfs;
15509 that's simpler and more reliable.
15510 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15511 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15512 sprintf, in case result does not fit in int.
15514 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15515 (fontset_from_font): Print it.
15517 * frame.c (tty_frame_count): Now printmax_t, not int.
15518 (make_terminal_frame, set_term_frame_name): Print it.
15519 (x_report_frame_params): In X, window IDs are unsigned long,
15520 not signed long, so print them as unsigned.
15521 (validate_x_resource_name): Check for implausibly long names,
15522 and don't assume name length fits in 'int'.
15523 (x_get_resource_string): Don't blindly alloca invocation name;
15524 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15527 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15528 (xg_check_special_colors, xg_set_geometry):
15529 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15531 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15532 Use esprintf, not sprintf, in case result does not fit in int.
15534 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15535 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15536 it as a large positive number.
15537 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15538 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15540 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15541 in case result does not fit in int.
15543 * print.c (float_to_string): Detect width overflow more reliably.
15544 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15545 buffer overrun. Don't assume list length fits in 'int'. Treat
15546 print length of 0 as 0, not as infinity; to be consistent with other
15547 uses of print length in this function. Don't overflow print length
15548 index. Don't assume hash table size fits in 'long', or that
15549 vectorlike size fits in 'unsigned long'.
15551 * process.c (make_process): Use printmax_t, not int, to format
15552 process-name gensyms.
15554 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15556 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15557 to avoid potential buffer overrun.
15559 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15560 if X resource line is longer than 512 bytes.
15562 * xfns.c (x_window): Make sprintf buffer a bit bigger
15563 to avoid potential buffer overrun.
15565 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15567 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15569 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15571 Integer overflow fixes for scrolling, etc.
15572 Without these, Emacs silently mishandles large integers sometimes.
15573 For example, "C-u 4294967297 M-x recenter" was treated as if
15574 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15576 * xdisp.c (try_window_id): Check Emacs fixnum range before
15577 converting to 'int'.
15579 * window.c (window_scroll_line_based, Frecenter):
15580 Check that an Emacs fixnum is in range before assigning it to 'int'.
15581 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15582 values converted from Emacs fixnums.
15583 (Frecenter): Don't wrap around a line count if it is out of 'int'
15584 range; instead, treat it as an extreme value.
15585 (Fset_window_configuration, compare_window_configurations):
15586 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15588 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15589 that can exceed INT_MAX. Check that EMACS_INT value is in range
15590 before assigning it to the (possibly-narrower) index.
15591 (match_limit): Don't assume that a fixnum can fit in 'int'.
15593 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15596 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15597 (Fvertical_motion): Don't wrap around LINES values that don't fit
15598 in 'int'. Instead, treat them as extreme values. This is good
15599 enough for windows, which can't have more than INT_MAX lines anyway.
15601 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15603 * Require libxml/parser.h to avoid compilation warning.
15605 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15607 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15608 since this reportedly can destroy thread storage.
15610 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15612 * syntax.c (find_defun_start): Update all cache variables if
15613 exiting early (Bug#9401).
15615 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15617 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15619 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15620 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15621 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15623 * term.c (tty_append_glyph): New function.
15624 (produce_stretch_glyph): Static function and its prototype deleted.
15626 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15629 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15631 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15632 when checking :margin (Bug#9390).
15633 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15634 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15635 so that the name doesn't mislead. All uses changed.
15637 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15639 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15642 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15644 * xdisp.c (move_it_to): Don't bail out early when reaching
15645 position beyond to_charpos, if we are scanning backwards.
15646 (move_it_vertically_backward): When DY == 0, make sure we get to
15647 the first character in the line after the newline.
15649 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15651 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15652 (ccl_driver): Do not generate an out-of-range pointer.
15653 (Fccl_execute_on_string): Remove unnecessary check for
15654 integer overflow, noted by Stefan Monnier in
15655 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15656 Remove a FIXME that didn't need fixing.
15657 Simplify the newly-introduced buffer reallocation code.
15659 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15661 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15663 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15665 Integer and memory overflow issues (Bug#9196).
15667 * doc.c (get_doc_string): Rework so that
15668 get_doc_string_buffer_size is the actual buffer size, rather than
15669 being 1 less than the actual buffer size; this makes xpalloc more
15672 * image.c (x_allocate_bitmap_record, cache_image):
15673 * xselect.c (Fx_register_dnd_atom):
15674 Simplify previous changes by using xpalloc.
15676 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15677 since either will do and ptrdiff_t is convenient with xpalloc.
15679 * charset.c (charset_table_size)
15680 (struct charset_sort_data.priority): Now ptrdiff_t.
15681 (charset_compare): Don't overflow if priorities differ greatly.
15682 (Fsort_charsets): Don't assume list length fits in int.
15683 Check for size-calculation overflow when allocating sort data.
15684 (syms_of_charset): Allocate an initial charset table that is
15685 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15687 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15689 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15690 The actual value is always <= INT_MAX, and leaving it unsigned made
15691 overflow checking harder.
15693 * dispextern.h (struct glyph_matrix.rows_allocated)
15694 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15695 with xpalloc. The values are still always <= INT_MAX.
15697 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15699 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15700 (SAFE_NALLOCA): New macro.
15702 * region-cache.c (struct boundary.pos, find_cache_boundary)
15703 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15704 (set_cache_region, invalidate_region_cache)
15705 (revalidate_region_cache, know_region_cache, region_cache_forward)
15706 (region_cache_backward, pp_cache):
15707 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15708 so that ptrdiff_t * can be passed to xpalloc.
15709 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15710 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15711 (pp_cache): Don't assume cache_len fits in int.
15712 * region-cache.h: Adjust extern decls to match.
15714 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15715 EMACS_INT, since either will do, for xpalloc.
15717 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15718 (xnmalloc, xnrealloc, xpalloc): New functions.
15720 * bidi.c (bidi_shelve_header_size): New constant.
15721 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15722 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15724 * bidi.c (bidi_cache_shrink):
15725 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15727 Don't update size of array until after memory allocation succeeds,
15728 because xmalloc/xrealloc may not return.
15729 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15730 now that we have proper integer overflow checking.
15731 (record_overlay_string, overlay_strings): Catch overflows when
15732 calculating size of overlay_str_buf.
15734 * callproc.c (Fcall_process): Check for size overflow when
15735 calculating size of args2.
15736 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15737 Normally we prefer signed values, but sticking with ptrdiff_t would
15738 require adding more-complicated checks.
15740 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15741 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15742 Redo buffer-overflow calculations to avoid integer overflow.
15743 Add a FIXME comment where memory seems to be over-allocated.
15745 * character.c (Fstring): Check for size-calculation overflow.
15747 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15748 unnecessary integer overflow. Check for size overflow.
15749 (encode_coding_object): Don't update size until xmalloc succeeds.
15751 * composite.c (get_composition_id): Check for overflow in glyph
15752 length calculations.
15754 Integer and memory overflow fixes for display code.
15755 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15756 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15757 (scrolling_window): Check for overflow in size calculations.

15769 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15770 (get_doc_string): Check for size calculation overflow.
15771 Don't update size until allocation succeeds.
15772 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15773 EMACS_INT, where ptrdiff_t will do.
15774 (Fsubstitute_command_keys): Check for string overflow.
15776 * editfns.c (set_time_zone_rule): Don't assume environment length
15778 (message_length): Now ptrdiff_t, not int.
15779 (Fmessage_box): Don't update size until allocation succeeds.
15780 Don't assume message length fits in int.
15781 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15783 * emacs.c (main): Do not reallocate argv, since there is a null at
15784 the end that can be overwritten, and this way there's no need to
15785 worry about size-calculation overflow.
15786 (sort_args): Check for size-calculation overflow.
15788 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15790 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15792 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15793 (x_set_scroll_bar_width, x_figure_window_size):
15794 Check for integer overflow.
15795 (x_set_alpha): Do not assume XINT fits in int.
15797 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15798 This is for the members text_lines, text_cols, total_lines, total_cols,
15799 where the system imposes an 'int' limit.
15801 * fringe.c (Fdefine_fringe_bitmap):
15802 Don't update size until alloc works.
15804 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15805 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15807 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15808 Check for size-calculation overflow.
15809 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15810 do, as we prefer signed integers.
15811 (id_to_widget.max_size, id_to_widget.used)
15812 (xg_store_widget_in_map, xg_remove_widget_from_map)
15813 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15814 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15815 Use and return ptrdiff_t, not int.
15816 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15817 * gtkutil.h: Change prototypes to match the above.
15819 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15820 are duplicate now that they've been promoted to lisp.h.
15821 (x_allocate_bitmap_record, x_alloc_image_color)
15822 (make_image_cache, cache_image, xpm_load):
15823 Don't update size until alloc is done.

15827 (ct_colors_allocated_max): New constant.
15828 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

15834 Use ptrdiff_t, not int, to count maps.
15835 (read_char_minibuf_menu_prompt): Check for overflow in size
15836 calculations. Don't update size until allocation succeeds.
15837 Redo calculations to avoid overflow.
15838 * keyboard.h: Change prototypes to match the above.
15840 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15842 (current_minor_maps): Check for size calculation overflow.
15843 * keymap.h: Change prototypes to match the above.
15845 * lread.c (read1, init_obarray): Don't update size until alloc done.

15851 Now ptrdiff_t, not int.
15852 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15864 (Fset_match_data): Don't assume list lengths fit in 'int'.
15866 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15867 for command line length. Do not attempt to address one before the
15868 beginning of an array, as that's not portable.
15870 * term.c (max_frame_lines): Remove; unused.
15871 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15873 (encode_terminal_code, calculate_costs): Check for size

15877 done. Redo calculations to avoid overflow.
15878 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15880 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15881 subtracting pointers.
15882 (gobble_line): Check for overflow more carefully. Don't update size
15885 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

15896 Use ptrdiff_t, not int, for sizes.
15897 (Finternal_make_lisp_face, cache_face):
15898 Check for size calculation overflow.
15899 (cache_face): Treat size calculation overflows as if they were
15900 memory exhaustion (the usual treatment), rather than aborting.
15902 * xfns.c (x_encode_text, x_set_name_internal)
15903 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15904 sizes, since they can exceed INT_MAX in size. Check for size
15905 calculation overflow.

15908 (xg_select): Check for size calculation overflow.
15909 Don't update size until alloc done.
15911 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15912 as sprintf is limited to int lengths.
15914 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15915 (X_LONG_MIN): New macros.
15916 Use them to make the following changes clearer.
15917 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15918 This change doesn't affect the value now, but it may help remind
15919 future maintainers not to raise the value too much later.
15920 (SELECTION_QUANTUM): Remove, replacing with ...
15921 (selection_quantum): ... new function, which avoids overflow.
15923 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15924 assumption that selection length fits in 'int'.

15932 Redo calculations to avoid overflow.
15933 (x_reply_selection_request): When sending hint, ceiling it at
15934 X_LONG_MAX rather than relying on wraparound overflow to send
15936 (x_get_window_property, receive_incremental_selection)
15937 (lisp_data_to_selection_data, x_property_data_to_lisp):
15938 Check for size-calculation overflow.
15939 (x_get_window_property, receive_incremental_selection)
15940 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15941 Don't store size until memory allocation succeeds.
15942 (x_get_window_property): Plug memory leak on memory exhaustion.
15943 Don't double-block input; malloc is safe here. Don't assume 2**34
15944 - 4 fits in unsigned long. Add an xassert to check
15945 XGetWindowProperty overflow. Be more careful about overflow
15946 calculations, and distinguish size from memory overflow better.
15947 (receive_incremental_selection): When tracing, don't assume
15948 unsigned int is less than INT_MAX.
15949 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15950 harmful) conversions of unsigned short to int.
15951 (lisp_data_to_selection_data): Don't assume that integers
15952 in the range -65535 through -1 fit in an X unsigned short.
15953 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15954 result parameters unless successful. Rely on cons_to_unsigned
15955 to report problems with elements; the old code wasn't right anyway.
15956 (x_check_property_data): Check for int overflow; we cannot use
15957 a wider type due to X limits.
15958 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15960 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15989 * image.c (xpm_get_color_table_h):
15990 * lisp.h (hash_lookup, hash_put):
15991 * minibuf.c (Ftest_completion):
15992 Use ptrdiff_t for hash table indexes, not int (which is too
15993 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15994 32-bit --with-wide-int hosts).
15996 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15997 Add a FIXME comment about memory leaks.
15998 (syms_of_charset): Don't assume xmalloc returns.
16000 Don't assume that stated character widths fit in int.

16002 * character.h (CHAR_WIDTH):
16003 * indent.c (MULTIBYTE_BYTES_WIDTH):
16004 Use sanitize_char_width to avoid undefined and/or bad behavior
16005 with outlandish widths.
16006 * character.h (sanitize_tab_width): Rename from sanitize_width,
16007 now that we have two such functions. All uses changed.
16008 (sanitize_char_width): New inline function.
16010 Don't assume that tab-width fits in int.
16011 * character.h (sanitize_width): New inline function.

16018 * fileio.c: Integer overflow issues with file modes.
16019 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16021 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16022 Remove unreachable code.
16023 (read_hex, load_charset_map_from_file): Check for integer overflow.
16025 * xterm.c: Don't go over XClientMessageEvent limit.
16026 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16027 (x_send_scroll_bar_event): Likewise. Check that the size does not
16028 exceed limits imposed by XClientMessageEvent, as well as the usual
16029 ptrdiff_t and size_t limits.
16031 * keyboard.c: Overflow, signedness and related fixes.
16032 (make_lispy_movement): Use same integer type in forward decl
16033 that is used in the definition.
16034 (read_key_sequence, keyremap_step):
16035 Change bufsize argument back to int, undoing my 2011-03-30 change.
16036 We prefer signed types, and int is wide enough here.
16037 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16038 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16039 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16040 length, not size_t. Use ptrdiff_t for index, not int.
16041 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16042 possibility of integer overflow.
16044 Overflow, signedness and related fixes for images.

16063 when the callers expect that.
16064 (image_ascent): Redo ascent calculation to avoid int overflow.
16065 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16066 (lookup_image): Remove unnecessary tests.
16067 (xbm_image_p): Locals are now of int, not EMACS_INT,
16068 since parse_image_check makes sure they fit into int.
16069 (png_load, gif_load, svg_load_image):
16070 Prefer int to unsigned where either will do.
16071 (tiff_handler): New function, combining the cores of the
16072 old tiff_error_handler and tiff_warning_handler.
16073 This function is rewritten to use vsnprintf and thereby avoid
16074 stack buffer overflows. It uses only the features of vsnprintf
16075 that are common to both POSIX and native Microsoft.
16076 (tiff_error_handler, tiff_warning_handler): Use it.
16077 (tiff_load, gif_load, imagemagick_load_image):
16078 Don't assume :index value fits in 'int'.
16079 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16080 (imagemagick_load_image): Check that crop parameters fit into
16081 the integer types that MagickCropImage accepts. Don't assume
16082 Vimagemagick_render_type has a nonnegative value. Don't assume
16083 size_t fits in 'long'.
16084 (gs_load): Use printmax_t to print the widest integers possible.
16085 Check for integer overflow when computing image height and width.

16097 handle_single_display_spec, not just 1 or zero.
16098 (handle_single_display_spec): If the display spec is of the form
16099 `(space ...)', and specifies display in the text area, return 2
16101 (try_cursor_movement): Check for the need to scroll more
16102 accurately, and prefer exact match for point under bidi.
16103 Don't advance `row' beyond the last row of the window.
16105 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16106 into disp_prop; all users changed.
16108 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

16120 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16121 buffers, return left-to-right.
16122 (set_cursor_from_row): Consider candidate row a win if its glyph
16123 represents a newline and point is on that newline. Fixes cursor
16124 positioning on the newline at EOL of R2L text within L2R
16125 paragraph, and vice versa.
16126 (try_cursor_movement): Check continued rows, in addition to
16127 continuation rows. Fixes unwarranted scroll when point enters a
16128 continued line of R2L text within an L2R paragraph, or vice versa.
16129 (cursor_row_p): Consider the case of point being equal to
16130 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16131 from the end of a short line to the beginning of a continued line
16132 of R2L text within L2R paragraph.
16133 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16134 composed characters.

16149 2011-08-22 Kenichi Handa <handa@m17n.org>
16151 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16152 extra slot even if the purpose is char-code-property-table.
16154 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16156 * xdisp.c (redisplay_window): When computing centering_position,
16157 account for the height of the header line. (Bug#8874)
16159 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16160 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16161 candidate is selected by the mouse, and that candidate has a
16162 composed character under the mouse.
16164 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16165 coordinates reported by pos-visible-in-window-p for a composed
16166 character in column zero.
16168 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16170 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16172 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16174 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16175 consider it a hit if to_charpos is anywhere in the range of the
16176 composed buffer positions.
16178 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16180 * image.c (gif_load): Don't assume that each subimage has the same
16181 dimensions as the base image. Handle disposal method that is
16182 "undefined" by the gif spec (Bug#9335).
16184 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16186 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16191 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16192 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16193 from an Org mode buffer to a Speedbar frame.
16195 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16196 a composition, take its buffer position from IT->cmp_it.charpos.
16197 Fixes cursor positioning at the beginning of a line that begins
16198 with a composed character.
16200 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16202 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16203 character bidirectional type, use STRONG_L instead. Fixes crashes
16204 in a buffer produced by `describe-categories'.
16206 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16207 members before the level stack, so they would be saved and
16208 restored when copying iterator state. Fixes incorrect reordering
16209 around TABs covered by display properties.
16211 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16213 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16283 * xdisp.c (move_it_in_display_line_to): Don't invoke
16284 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16285 ppos_it. Fixes vertical cursor motion when line beginning is
16286 covered by an image. (Bug#9296)
16288 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16290 * nsterm.h (ns_run_ascript): Declare.

16294 (ns_run_ascript): New function.
16295 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16296 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16297 the event loop. Get status from as_status (Bug#7276).
16299 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16300 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16301 the event loop (Bug#7276).
16303 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

16327 (Fnetwork_interface_list): Allocate in increments of bytes instead
16328 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16329 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16331 (struct ifflag_def): notrailers is smart on OSX.
16332 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16333 Get hardware address with getifaddrs if available.
16335 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16337 * xdisp.c (iterate_out_of_display_property): xassert that
16338 IT->position is set to within IT->object's boundaries. Break from

16341 Set IT->current to match the bidi iterator unconditionally.
16342 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16343 entry. Force push_it to save on the stack the current
16344 buffer/string position, to be restored by pop_it. Fix flags in
16345 the iterator structure wrt the object coming from a display
16346 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16347 properties. (Bug#9284)
16349 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16351 * fontset.c (fontset_get_font_group): Add proper type checks.

16379 restore_point_unwind (Bug#5984).
16381 2011-08-07 Juri Linkov <juri@jurta.org>
16383 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16384 to show the arg `TIME' instead of `TIMEVAL'.
16386 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16388 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16389 display property strides EOL and includes a newline, as in
16390 longlines-mode. (Bug#9254)
16391 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16392 word-wrap under bidirectional display. (Bug#9224)
16394 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16395 is non-zero, even if the data buffer is NULL. Fixes a crash in
16396 vertical-motion with longlines-mode. (Bug#9254)
16398 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16400 * bidi.c <bidi_cache_total_alloc>: Now static.

16403 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16406 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16407 amount allocated this far in `bidi_cache_total_alloc'.
16408 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16409 non-zero, only free the data buffer without restoring the cache
16410 contents. All callers changed.
16412 * dispextern.h (bidi_unshelve_cache): Update prototype.
16414 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16415 (move_it_in_display_line, move_it_to)
16416 (move_it_vertically_backward, move_it_by_lines): Replace the call
16417 to xfree to an equivalent call to bidi_unshelve_cache.
16418 (move_it_in_display_line_to): Fix logic of returning
16419 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16421 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16423 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

16470 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16471 for a display string or property. If found, set DISP_PROP_P
16474 * bidi.c (bidi_fetch_char): Accept an additional argument
16475 DISP_PROP_P, and pass it to compute_display_string_pos.
16476 Only handle text covered by a display string if DISP_PROP_P is returned
16477 non-zero. All callers of bidi_fetch_char changed.
16479 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16481 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16483 2010-12-03 Don March <don@ohspite.net>
16485 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16486 last character M-[char] is translated to ESC [char] (bug#7541).
16488 2011-08-02 Kenichi Handa <handa@m17n.org>
16490 * lisp.h (uniprop_table): Extern it.
16492 * chartab.c (uniprop_table): Make it non-static.
16494 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16496 * xdisp.c (forward_to_next_line_start): Accept additional argument
16497 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16499 (reseat_at_next_visible_line_start): Use the bidi iterator state
16500 returned by forward_to_next_line_start to restore the state of
16501 it->bidi_it after backing up to previous newline. (Bug#9212)
16503 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16505 * regex.c (re_comp): Protoize.
16506 (re_exec): Fix return type.
16507 (regexec): Fix type of `ret'. (Bug#9203)
16509 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16511 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16512 This is needed if max-image-size is a floating-point number.
16514 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16516 * print.c (print_object): Print empty symbol as ##.
16518 * lread.c (read1): Read ## as empty symbol.
16520 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16522 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16523 setting frame foreground color (Bug#9175).
16524 (x_set_background_color): Likewise.
16526 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16527 contents (Bug#9176).
16528 (EmacsTooltip -init): Remove bezels and add shadows to
16531 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16532 or scroll bar (Bug#8470).
16534 * nsfont.m (nsfont_open): Remove assignment to voffset and
16535 unnecessary vars hshink, expand, hd, full_height, min_height.
16536 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16538 * nsterm.h (nsfont_info): Remove voffset field.
16540 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16542 Implement strike-through and overline on NextStep (Bug#8863).
16544 * nsfont.m (nsfont_open): Use underline position provided by font,
16545 instead of hard-coded value of 2.
16546 (nsfont_draw): Call ns_draw_text_decoration instead.
16548 * nsterm.h: Add declaration for ns_draw_text_decoration.
16550 * nsterm.m (ns_draw_text_decoration): New function for drawing
16551 underline, overline, and strike-through.
16552 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16553 ns_draw_text_decoration. Change treatment of cursor drawing to
16554 accommodate underlining, etc.
16556 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16558 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16561 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16563 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16564 Without this fix, if a signal arrives just after memory fills up,
16565 'malloc' might be invoked reentrantly.
16567 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16568 In other words, assume that every image size is allowed, on non-X
16569 hosts. This assumption is probably wrong, but it lets Emacs compile.
16571 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16573 * regex.c (re_iswctype): Convert return values to boolean.
16575 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16577 * xdisp.c (compute_display_string_pos): Don't use cached display
16578 string position if the buffer had its restriction changed.
16581 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16583 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16585 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16587 Integer signedness and overflow and related fixes. (Bug#9079)
16589 * bidi.c: Integer size and overflow fixes.
16590 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16591 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16592 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16593 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16594 (bidi_find_other_level_edge):
16595 Use ptrdiff_t instead of EMACS_INT where either will do.
16596 This works better on 32-bit hosts configured --with-wide-int.
16597 (bidi_cache_ensure_space): Check for size-calculation overflow.
16598 Use % rather than repeated addition, for better worst-case speed.
16599 Don't set bidi_cache_size until after xrealloc returns, because it
16601 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16602 (bidi_cache_ensure_space): Also check that the bidi cache size
16603 does not exceed that of the largest Lisp string or buffer. See Eli
16604 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16606 * alloc.c (__malloc_size_t): Remove.
16607 All uses replaced by size_t. See Andreas Schwab's note
16608 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16610 * image.c: Improve checking for integer overflow.
16611 (check_image_size): Assume that f is nonnull, since
16612 it is always nonnull in practice. This is one less thing to
16613 worry about when checking for integer overflow later.
16614 (x_check_image_size): New function, which checks for integer
16615 overflow issues inside X.
16616 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16617 This removes the need for a memory_full check.
16618 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16619 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16620 (xbm_read_bitmap_data): Change locals back to 'int', since
16621 their values must fit in 'int'.
16622 (xpm_load_image, png_load, tiff_load):
16623 Invoke x_create_x_image_and_pixmap earlier,
16624 to avoid much needless work if the image is too large.
16625 (tiff_load): Treat overly large images as if
16626 x_create_x_image_and_pixmap failed, not as malloc failures.
16627 (gs_load): Use x_check_image_size.
16629 * gtkutil.c: Omit integer casts.
16630 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16631 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16633 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16635 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16636 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16637 would wrongly return t on a 64-bit host.
16639 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16640 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16641 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16642 and therefore cause GCC to emit a bogus diagnostic in some cases.
16644 * image.c: Integer signedness and overflow and related fixes.
16645 This is not an exhaustive set of fixes, but it's time to
16646 record what I've got.
16647 (lookup_pixel_color, check_image_size): Remove redundant decls.
16648 (check_image_size): Don't assume that arbitrary EMACS_INT values
16649 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16650 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16651 (tiff_load, imagemagick_load_image):
16652 Check for overflow in size calculations.
16653 (x_create_x_image_and_pixmap): Remove unnecessary test for
16654 xmalloc returning NULL; that can't happen.
16655 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16656 (xpm_color_bucket): Use better integer hashing function.
16657 (xpm_cache_color): Don't possibly over-allocate memory.
16658 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16659 (gif_memory_source):
16660 Use ptrdiff_t, not int or size_t, to record sizes.
16661 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16662 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16663 either works, as we prefer signed integers.
16664 (tiff_read_from_memory, tiff_write_from_memory):
16665 Return tsize_t, not size_t, since that's what the TIFF API wants.
16666 (tiff_read_from_memory): Don't fail simply because the read would
16667 go past EOF; instead, return a short read.
16668 (tiff_load): Omit no-longer-needed casts.
16669 (Fimagemagick_types): Don't assume size fits into 'int'.
16671 Improve hashing quality when configured --with-wide-int.
16672 * fns.c (hash_string): New function, taken from sxhash_string.
16673 Do not discard information about ASCII character case; this
16674 discarding is no longer needed.
16675 (sxhash-string): Use it. Change sig to match it. Caller changed.
16676 * lisp.h: Declare it.
16677 * lread.c (hash_string): Remove, since we now use fns.c's version.
16678 The fns.c version returns a wider integer if --with-wide-int is
16679 specified, so this should help the quality of the hashing a bit.
16681 * emacs.c: Integer overflow minor fix.
16682 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16683 Define only if GNU_LINUX.
16684 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16686 * dispnew.c: Integer signedness and overflow fixes.
16687 Remove unnecessary forward decls, that were a maintenance hassle.
16688 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16690 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16691 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16692 (prepare_desired_row, line_draw_cost):
16693 Use int, not unsigned, where either works.
16694 (save_current_matrix, restore_current_matrix):
16695 Use ptrdiff_t, not size_t, where either works.
16696 (init_display): Check for overflow more accurately, and without
16697 relying on undefined behavior.
16699 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16700 Remove, replacing with the new symbols in lisp.h. All uses changed.
16701 * fileio.c (make_temp_name):
16702 * filelock.c (lock_file_1, lock_file):
16703 * xdisp.c (message_dolog):
16704 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16705 Use pMd etc. instead.
16706 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16707 replacing the pWIDE etc. symbols removed from editfns.c.
16709 * keyboard.h (num_input_events): Now uintmax_t.
16710 This is (very slightly) less likely to mess up due to wraparound.
16713 * buffer.c: Integer signedness fixes.
16714 (alloc_buffer_text, enlarge_buffer_text):
16715 Use ptrdiff_t rather than size_t when either will do, as we prefer
16718 * alloc.c: Integer signedness and overflow fixes.
16719 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16720 (__malloc_size_t): Default to size_t, not to int.
16721 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16722 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16723 Prefer ptrdiff_t to size_t when either would do, as we prefer
16725 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16726 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16727 Now const. Initialize with values that are in range even if char
16729 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16730 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16731 These functions do the right thing with sizes > 2**32.
16732 (check_depth): Now ptrdiff_t, not int.
16733 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16734 Adjust to new way of storing sizes. Check for size overflow bugs
16736 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16737 slightly wrong anyway, as it missed one instance of
16738 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16739 (refill_memory_reserve): Omit needless cast to size_t.
16740 (mark_object_loop_halt): Mark as externally visible.
16742 * xselect.c: Integer signedness and overflow fixes.
16743 (Fx_register_dnd_atom, x_handle_dnd_message):
16744 Use ptrdiff_t, not size_t, since we prefer signed.
16745 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16746 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16747 x_dnd_atoms_size and x_dnd_atoms_length.
16749 * doprnt.c: Prefer signed to unsigned when either works.
16751 * doprnt.c (doprnt):
16753 * xdisp.c (vmessage):
16754 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16755 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16756 prefer signed arithmetic to avoid comparison confusion.
16757 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16758 but is a bit tricky.
16760 Assume freestanding C89 headers, string.h, stdlib.h.
16761 * data.c, doprnt.c, floatfns.c, print.c:
16762 Include float.h unconditionally.
16763 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16764 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16765 * regex.c: Likewise for stddef.h, string.h.
16766 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16767 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16768 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16769 (STDC_HEADERS): Remove obsolete defines.
16770 * sysdep.c: Include limits.h unconditionally.
16772 Assume support for memcmp, memcpy, memmove, memset.
16773 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16774 * regex.c (memcmp, memcpy):
16775 Remove; we assume C89 now.
16777 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16778 (__malloc_safe_bcopy): Remove; no longer needed.
16780 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16781 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16782 well either way, and we prefer signed to unsigned.
16784 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16786 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16787 closes the connection while we're reading (bug#9182).
16789 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16791 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16792 are specified (Bug#9168).
16794 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16796 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16797 Found by GCC static checking and --with-wide-int on a 32-bit host.
16799 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16801 * xdisp.c (compute_display_string_pos): Fix logic of caching
16802 previous display string position. Initialize cached_prev_pos to
16803 -1. Fixes slow-down at the beginning of a buffer.
16805 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16807 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16808 for attrs[LFACE_FONTSET_INDEX].
16810 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16812 * xml.c (parse_region): Remove unused local
16813 that was recently introduced.
16815 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16817 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16818 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16820 * xdisp.c (move_it_in_display_line_to): Record the best matching
16821 position for TO_CHARPOS while scanning the line, and restore it on
16822 exit if none of the characters scanned was an exact match.
16823 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16824 when exact match is impossible due to invisible text, and the
16825 lines are truncated.
16827 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16829 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16832 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16834 Fix a significant slow-down of cursor motion with C-n, C-p,
16835 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16836 auto-repeat under bidi redisplay in fontified buffers.
16837 * xdisp.c (compute_stop_pos_backwards): New function.
16838 (next_element_from_buffer): Call compute_stop_pos_backwards to
16839 find a suitable prev_stop when we find ourselves before
16841 (reseat): Don't look for prev_stop, as that could mean a very long
16843 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16844 <cached_disp_overlay_modiff>: Cache for last found display string
16846 (compute_display_string_pos): Return the cached position if asked
16847 about the same buffer in the same area of character positions, and
16848 the buffer wasn't changed since the time the display string
16849 position was cached.
16851 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16853 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16854 is an integer, which is important for empty lines. (Bug#9149)
16856 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16858 * frame.c (Fmodify_frame_parameters): In tty case, update the
16859 default face if necessary (Bug#4238).
16861 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16863 * editfns.c (Fstring_to_char): No need to explain what a character
16864 is in the docstring (Bug#6576).
16866 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16868 * xml.c (parse_region): Make sure we always return a tree.
16870 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16872 * xml.c (parse_region): If a document contains only comments,
16875 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16877 * xml.c (make_dom): Return comments, too.
16879 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16882 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16883 and the surrounding thread.
16884 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16885 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16886 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16888 * s/openbsd.h (BROKEN_SIGIO): Define.
16889 * unexelf.c (unexec) [__OpenBSD__]:
16890 Don't update the .mdebug section of the Alpha COFF symbol table.
16892 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16894 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16897 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16899 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16900 This fixes some race conditions on the permissions of any newly
16903 * alloc.c (valid_pointer_p): Use pipe, not open.
16904 This fixes some permissions issues when debugging.
16906 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16907 If fchown fails to set both uid and gid, try to set just gid,
16908 as that is sometimes allowed. Adjust the file's mode to eliminate
16909 setuid or setgid bits that are inappropriate if fchown fails.
16911 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16913 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16914 to compare Lisp_Objects.

16929 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16930 This works around a problem with the previous change to Fcopy_file.
16931 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16932 and without this change, GCC might complain about discarding
16933 fchown's return value.
16935 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16937 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

16960 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16962 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16963 quotes the next character, and doesn't affect other longer
16964 sequences (bug#8935).
16966 * lread.c (syms_of_lread): Clarify that is isn't only
16967 `eval-buffer' and `eval-defun' that's affected by
16968 `lexical-binding' (bug#8460).

16978 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16979 (elsz): Now a signed constant, not a size_t var. We prefer signed
16980 types to unsigned, to avoid integer comparison confusion. Without
16981 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16982 "cannot optimize loop, the loop counter may overflow", a symptom
16984 * indent.c (Fvertical_motion): Mark locals as initialized.
16985 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16987 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

17031 the iterator is before prev_stop.
17032 (init_iterator): Initialize bidi_p from the default value of

17073 pushed the iterator stack, restore the internal state of the bidi
17074 iterator by calling bidi_pop_it same number of times.
17075 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17076 and we are bidi-iterating, don't decrement the iterator position;
17077 instead, set the first_elt flag in the bidi iterator, to produce
17079 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17080 (push_display_prop): xassert that we are iterating a buffer.

17084 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17085 correctly. Don't assume unibyte strings are not bidi-reordered.

17509 (clone_per_buffer_values): Don't assume that

17511 This isn't true in general, and it's particularly not true
17512 if Emacs is configured with --with-wide-int.
17513 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17514 New macros, used in the buffer.c change.

17550 Random fixes. E.g., (random) never returned negative values.
17551 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17552 subseconds part to the entropy, as that's a bit more random.
17553 Prefer signed to unsigned, since the signedness doesn't matter and
17554 in general we prefer signed. When given a limit, use a
17555 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17556 latter isn't right if USE_2_TAGS_FOR_INTS.
17557 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17558 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17570 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17571 This is more efficient than Ffile_directory_p and avoids a minor race.
17573 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17575 * buffer.c (Foverlay_put): Say what the return value is
17578 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17579 is a directory before asking whether to use the file name
17581 (barf_or_query_if_file_exists): Make the "File is a directory"
17582 error be more correct.
17584 * fns.c (Frequire): Remove the mention of the .gz files, since
17585 that's installation-specific, but keep the mention of
17586 `get-load-suffixes'.

17590 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17598 Qgnutls_bootprop_verify_error (which is no longer used).
17600 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17601 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17602 Also (re)move comments that are misplaced or no longer relevant.

17627 leave any prefix arg for the up event (Bug#1586).
17629 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
17631 * lread.c (syms_of_lread): Mention single symbols defined by
17632 `defvar' or `defconst' (bug#7154).
17634 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17635 (Frequire): Mention get-load-suffixes.

17703 * eval.c (struct backtrace): Simplify and port the data structure.
17704 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17705 signed bit field, as this assumption is not portable and it makes
17706 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17707 "char debug_on_exit : 1" as this is not portable either; instead,
17708 use the portable "unsigned int debug_on_exit : 1". Remove unused
17709 member evalargs. Remove obsolete comments about cc bombing out.
17711 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17791 2011-06-26 Eli Zaretskii <eliz@gnu.org>
17793 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
17794 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
17797 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
17799 * process.c (wait_reading_process_output): Bypass select if
17800 waiting for a cell while ignoring keyboard input, and input is
17801 pending. Suggested by Jan Djärv (Bug#8869).
17803 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
17805 Use gnulib's dup2 module instead of rolling our own.
17806 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17808 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17810 * dispnew.c (scrolling_window): Before scrolling, turn off a
17811 mouse-highlight in the window being scrolled.
17813 2011-06-24 Juanma Barranquero <lekktu@gmail.com>

17873 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17875 Integer and buffer overflow fixes (Bug#8873).
17877 * print.c (printchar, strout): Check for string overflow.
17878 (PRINTPREPARE, printchar, strout):
17879 Don't set size unless allocation succeeds.
17881 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17882 for sizes. Check for string overflow more accurately.
17883 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17885 * macros.c: Integer and buffer overflow fixes.
17886 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17887 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17888 Use ptrdiff_t, not int, for sizes.
17889 Don't increment bufsize until after realloc succeeds.
17890 Check for size-calculation overflow.
17891 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17893 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17895 * lread.c: Integer overflow fixes.
17896 (read_integer): Radix is now EMACS_INT, not int,
17897 to improve quality of diagnostics for out-of-range radices.
17898 Calculate buffer size correctly for out-of-range radices.
17899 (read1): Check for integer overflow in radices, and in
17900 read-circle numbers.
17901 (read_escape): Avoid int overflow.
17902 (Fload, openp, read_buffer_size, read1)
17903 (substitute_object_recurse, read_vector, read_list, map_obarray):
17904 Use ptrdiff_t, not int, for sizes.

17919 2011-06-22 Leo Liu <sdl.web@gmail.com>
17921 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17922 Move to minibuffer.el.
17924 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17926 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17927 The following patches are for when GLYPH_DEBUG && !XASSERT.
17928 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17929 * dispnew.c (flush_stdout):
17930 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17931 Mark as externally visible.
17932 * dispnew.c (check_window_matrix_pointers): Now static.
17933 * dispnew.c (window_to_frame_vpos):
17934 * xfns.c (unwind_create_frame):
17935 * xterm.c (x_check_font): Remove unused local.
17936 * scroll.c (CHECK_BOUNDS):
17937 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17938 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17939 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17940 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17941 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17943 (debug_method_add): Use va_list and vsprintf rather than relying
17944 on undefined behavior with wrong number of arguments.
17945 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17946 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17947 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17948 since we're not interested in debugging glyphs with old libraries.
17949 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17950 GCC 4.6.0's static checking.
17952 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17954 Integer overflow and signedness fixes (Bug#8873).

17963 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17964 (x_create_bitmap_from_xpm_data):
17965 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17966 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17968 * xfaces.c (load_pixmap):

17970 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17971 (.bitmaps_last, struct x_output.icon_bitmap):
17972 Use ptrdiff_t, not int, for bitmap indexes.
17973 (x_allocate_bitmap_record): Check for size overflow.
17974 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17976 Use ptrdiff_t, not int, for overlay counts.
17977 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17978 * editfns.c (overlays_around, get_pos_property):
17979 * textprop.c (get_char_property_and_overlay):
17980 * xdisp.c (next_overlay_change, note_mouse_highlight):
17981 * xfaces.c (face_at_buffer_position):
17982 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17983 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17984 (Fnext_overlay_change, Fprevious_overlay_change)
17985 (mouse_face_overlay_overlaps, Foverlays_in):
17986 Use ptrdiff_t, not int, for sizes.
17987 (overlays_at, overlays_in): Check for size-calculation overflow.
17989 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17991 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17992 (x_session_initialize): Do not assume string length fits in int.
17994 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17995 This is unlikely, but can occur if DPI is outlandish.
17997 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17998 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18000 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18001 * xrdb.c (magic_file_p, search_magic_path):
18002 Omit last arg SUFFIX; it was always 0. All callers changed.
18003 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18005 * xfont.c (xfont_match): Avoid need for strlen.
18007 * xfns.c: Don't assume strlen fits in int.
18008 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18010 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18011 not unsigned long, as we prefer signed integers. All callers changed.
18012 Detect integer overflow in repeat count.
18013 (message_dolog): Don't assume print length fits in 39 bytes.
18014 (display_mode_element): Don't assume strlen fits in int.
18016 * termcap.c: Don't assume sizes fit in int and never overflow.
18017 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18018 (gobble_line): Check for size-calculation overflow.
18020 * minibuf.c (Fread_buffer):
18021 * lread.c (intern, intern_c_string):
18022 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

18026 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18028 * font.c: Don't assume string length fits in int.
18029 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18030 Use ptrdiff_t, not int.
18031 (font_intern_prop): Don't assume string length fits in int.
18032 Don't assume integer property fits in fixnum.
18033 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18035 * filelock.c: Fix some buffer overrun and integer overflow issues.
18036 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18037 Reformulate so as not to need the command string.
18038 Invoke gzip -cd rather than gunzip, as it's more portable.
18039 (lock_info_type, lock_file_1, lock_file):
18040 Don't assume pid_t and time_t fit in unsigned long.
18041 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18042 (current_lock_owner): Prefer signed type for sizes.
18043 Use memcpy, not strncpy, where memcpy is what is really wanted.
18044 Don't assume (via atoi) that time_t and pid_t fit in int.
18045 Check for time_t and/or pid_t out of range, e.g., via a network share.
18046 Don't alloca where an auto var works fine.
18048 * fileio.c: Fix some integer overflow issues.
18049 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18050 Don't assume string length fits in int.
18051 (directory_file_name): Don't assume string length fits in long.
18052 (make_temp_name): Don't assume pid fits in int, or that its print
18053 length is less than 20.
18055 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18057 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18059 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18061 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18062 We prefer signed integers, even for size calculations.
18064 * emacs.c: Don't assume string length fits in 'int'.
18065 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18066 (main): Don't invoke strlen when not needed.
18068 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18069 (XD_DEBUG_MESSAGE): Don't waste a byte.
18071 * callproc.c (getenv_internal_1, getenv_internal)
18072 (Fgetenv_internal):
18073 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18075 * lread.c (invalid_syntax): Omit length argument.
18076 All uses changed. This doesn't fix a bug, but it simplifies the
18077 code away from its former Hollerith-constant appearance, and it's
18078 one less 'int' to worry about when looking at integer-overflow issues.
18079 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18081 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18082 This didn't break anything, but it didn't help either.
18083 It's confusing to put a bogus integer in a place where the actual
18084 value does not matter.
18085 (LIST_END_P): Remove unused macro and its bogus comment.
18086 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18088 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18089 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18091 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18092 We prefer signed types, and the value cannot exceed the EMACS_INT
18093 range anyway (because otherwise the length would not be representable).
18094 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18095 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18096 This avoids a GCC warning when WIDE_EMACS_INT.
18098 * indent.c (sane_tab_width): New function.
18099 (current_column, scan_for_column, Findent_to, position_indentation)
18100 (compute_motion): Use it. This is just for clarity.
18101 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18103 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18105 * lisp.h (lint_assume): New macro.
18106 * composite.c (composition_gstring_put_cache):
18107 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18109 * editfns.c, insdel.c:
18110 Omit unnecessary forward decls, to simplify future changes.
18112 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18114 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18116 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18117 Use much-faster test for byte-length change.
18118 Don't assume string byte-length fits in 'int'.
18119 Check that character arg fits in 'int'.
18120 (mapcar1): Declare byte as byte, for clarity.
18122 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18124 * fns.c (concat): Catch string overflow earlier.
18125 Do not rely on integer wraparound.
18127 * dispextern.h (struct it.overlay_strings_charpos)
18128 (struct it.selective): Now EMACS_INT, not int.
18129 * xdisp.c (forward_to_next_line_start)
18130 (back_to_previous_visible_line_start)
18131 (reseat_at_next_visible_line_start, next_element_from_buffer):
18132 Don't arbitrarily truncate the value of 'selective' to int.
18134 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18136 * composite.c: Don't truncate sizes to 'int'.
18137 (composition_gstring_p, composition_reseat_it)
18138 (composition_adjust_point): Use EMACS_INT, not int.
18139 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18140 not EMACS_UINT, for indexes.
18142 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18144 * buffer.c: Include <verify.h>.
18145 (struct sortvec.priority, struct sortstr.priority):
18146 Now EMACS_INT, not int.
18147 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18148 (struct sortstr.size, record_overlay_string)
18149 (struct sortstrlist.size, struct sortlist.used):
18150 Don't truncate size to int.
18151 (record_overlay_string): Check for size-calculation overflow.
18152 (init_buffer_once): Check at compile-time, not run-time.
18154 2011-06-22 Jim Meyering <meyering@redhat.com>
18156 Don't leak an XBM-image-sized buffer
18157 * image.c (xbm_load): Free the image buffer after using it.
18159 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18162 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18163 that Sun C diagnosed.
18164 * fns.c (secure_hash): Fix pointer signedness issue.
18165 * intervals.c (static_offset_intervals): New function.
18166 (offset_intervals): Use it.
18168 2011-06-21 Leo Liu <sdl.web@gmail.com>
18171 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18174 * fns.c (secure_hash): Rename from crypto_hash_function and change
18175 the first arg to accept symbols.
18176 (Fsecure_hash): New primitive.
18177 (syms_of_fns): New symbols.
18179 2011-06-20 Deniz Dogan <deniz@dogan.se>
18181 * process.c (Fset_process_buffer): Clarify return value in
18184 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18186 * dispnew.c (add_window_display_history): Use BVAR.
18188 * xdisp.c (debug_method_add): Use BVAR.
18189 (check_window_end, dump_glyph_matrix, dump_glyph)
18190 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18192 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18195 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18196 check till after the cache is created in init_frame_faces.
18198 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18200 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18202 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18204 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18205 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18206 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18208 Improve buffer-overflow checking (Bug#8873).
18209 * fileio.c (Finsert_file_contents):
18210 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18211 Remove the old (too-loose) buffer overflow checks.
18212 They weren't needed, since make_gap checks for buffer overflow.
18213 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18214 The old code merely checked for Emacs fixnum overflow, and relied
18215 on undefined (wraparound) behavior. The new code avoids undefined
18216 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18218 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18219 Tune. Don't use wider integers than needed. Don't use alloca.
18220 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18222 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18224 * insdel.c, lisp.h (buffer_overflow): New function.
18225 (insert_from_buffer_1, replace_range, replace_range_2):
18226 * insdel.c (make_gap_larger):
18227 * editfns.c (Finsert_char):
18228 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18230 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18232 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18234 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18236 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18237 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18239 * fileio.c: Don't assume EMACS_INT fits in off_t.
18240 (emacs_lseek): New static function.
18241 (Finsert_file_contents, Fwrite_region): Use it.
18242 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18244 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18246 * fns.c: Don't overflow int when computing a list length.
18247 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18248 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18249 truncation on 64-bit hosts. Check for QUIT every
18250 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18251 faster and is responsive enough.
18252 (Flength): Report an error instead of overflowing an integer.
18253 (Fsafe_length): Return a float if the value is not representable
18254 as a fixnum. This shouldn't happen except in contrived situations.
18255 (Fnthcdr, Fsort): Don't assume list length fits in int.
18256 (Fcopy_sequence): Don't assume vector length fits in int.
18258 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18259 (header_size, word_size): New constants.
18260 (allocate_vectorlike): Don't check size overflow here.
18261 (allocate_vector): Check it here instead, since this is the only
18262 caller of allocate_vectorlike that could cause overflow.
18263 Check that the new vector's length is representable as a fixnum.
18265 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18266 The previous code was bogus. For example, next_almost_prime (32)
18267 returned 39, which is undesirable as it is a multiple of 3; and
18268 next_almost_prime (24) returned 25, which is a multiple of 5 so
18269 why was the code bothering to check for multiples of 7?
18271 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18273 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18275 Variadic C functions now count arguments with ptrdiff_t.
18276 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18277 Back then I didn't know that the Emacs coding style prefers signed int.
18278 Also, in the meantime I found a few more instances where arguments
18279 were being counted with int, which may truncate counts on 64-bit
18280 machines, or EMACS_INT, which may be unnecessarily wide.
18281 * lisp.h (struct Lisp_Subr.function.aMANY)
18282 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18283 Arg counts are now ptrdiff_t, not size_t.
18284 All variadic functions and their callers changed accordingly.
18285 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18286 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18287 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18288 * callint.c (Fcall_interactively): Check arg count for overflow,
18289 to avoid potential buffer overrun. Use signed char, not 'int',
18290 for 'varies' array, so that we needn't bother to check its size
18291 calculation for overflow.
18292 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18293 * eval.c (apply_lambda):
18294 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18295 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18296 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18298 * callint.c (Fcall_interactively): Don't use index var as event count.
18300 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18301 * mem-limits.h (SIZE): Remove; no longer used.
18303 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18305 Remove unnecessary casts.
18306 * xterm.c (x_term_init):
18307 * xfns.c (x_set_border_pixel):
18308 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18309 These aren't needed now that we assume ANSI C.
18311 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18312 It's more likely to cause problems (due to unsigned overflow)
18315 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18317 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18319 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18321 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18323 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18325 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18327 GLYPH_CODE_FACE returns EMACS_INT, not int.
18328 * dispextern.h (merge_faces):
18329 * xfaces.c (merge_faces):
18330 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18331 Don't assume EMACS_INT fits in int.
18333 * character.h (CHAR_VALID_P): Remove unused parameter.
18334 * fontset.c, lisp.h, xdisp.c: All uses changed.
18336 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18338 * fns.c (concat): Minor tuning based on overflow analysis.
18339 This doesn't fix any bugs. Use int to hold character, instead
18340 of constantly refetching from Emacs object. Use XFASTINT, not
18341 XINT, for value known to be a character. Don't bother comparing
18342 a single byte to 0400, as it's always less.
18344 * floatfns.c (Fexpt):
18345 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18347 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18350 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18352 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18353 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18354 incorrectly succeed when S was a string, because 4294967386 was
18355 truncated before it was used.
18357 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18358 Otherwise, an out-of-range integer could cause undefined behavior
18361 * composite.c: Use int, not EMACS_INT, for characters.
18362 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18363 EMACS_INT, for values that are known to be in character range.
18364 This doesn't fix any bugs but is the usual style inside Emacs and
18365 may generate better code on 32-bit machines.
18367 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18368 This is for reasons similar to the recent CHAR_STRING fix.
18369 * charset.c (Fencode_char): Check that character arg is actually
18370 a character. Pass an int to ENCODE_CHAR.
18371 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18372 wider than 'int', as a compile-time check to prevent future regressions
18375 * character.c (char_string): Remove unnecessary casts.
18377 Make sure a 64-bit char is never passed to CHAR_STRING.
18378 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18379 by silently ignoring the top 32 bits, allowing some values
18380 that were far too large to be valid characters.
18381 * character.h: Include <verify.h>.
18382 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18383 arguments are no wider than unsigned, as a compile-time check
18384 to prevent future regressions in this area.
18386 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18387 (Fsubst_char_in_region):
18389 * xdisp.c (decode_mode_spec_coding):
18390 Adjust to CHAR_STRING's new requirement.
18391 * editfns.c (Finsert_char, Fsubst_char_in_region):
18392 * fns.c (concat): Check that character args are actually
18393 characters. Without this test, these functions did the wrong
18394 thing with wildly out-of-range values on 64-bit hosts.
18396 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18397 These casts should not be needed on 32-bit hosts, either.
18398 * keyboard.c (read_char):
18399 * lread.c (Fload): Remove casts to unsigned.
18401 * lisp.h (UNSIGNED_CMP): New macro.
18402 This fixes comparison bugs on 64-bit hosts.
18403 (ASCII_CHAR_P): Use it.
18404 * casefiddle.c (casify_object):
18405 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18406 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18407 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18408 * dispextern.h (FACE_FROM_ID):
18409 * keyboard.c (read_char): Use UNSIGNED_CMP.
18411 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18412 not to EMACS_INT, to avoid GCC warning.
18414 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18416 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18417 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18418 isn't needed on 32-bit machines.
18420 * buffer.c (Fgenerate_new_buffer_name):
18421 Use EMACS_INT for count, not int.
18422 (advance_to_char_boundary): Return EMACS_INT, not int.
18424 * data.c (Qcompiled_function): Now static.
18426 * window.c (window_body_lines): Now static.
18428 * image.c (gif_load): Rename local to avoid shadowing.
18430 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18431 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18432 * alloc.c (make_save_value): Integer argument is now of type
18433 ptrdiff_t, not int.
18434 (mark_object): Use ptrdiff_t, not int.
18435 * lisp.h (pD): New macro.
18436 * print.c (print_object): Use it.
18438 * alloc.c: Use EMACS_INT, not int, to count objects.
18439 (total_conses, total_markers, total_symbols, total_vector_size)
18440 (total_free_conses, total_free_markers, total_free_symbols)
18441 (total_free_floats, total_floats, total_free_intervals)
18442 (total_intervals, total_strings, total_free_strings):
18443 Now EMACS_INT, not int. All uses changed.
18444 (Fgarbage_collect): Compute overall total using a double, so that
18445 integer overflow is less likely to be a problem. Check for overflow
18446 when converting back to an integer.
18447 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18448 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18449 These were 'int' variables that could overflow on 64-bit hosts;
18450 they were never used, so remove them instead of repairing them.
18451 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18452 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18453 Previously, this ceilinged at INT_MAX, but that doesn't work on
18455 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18457 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18458 (allocate_vectorlike): Check for ptrdiff_t overflow.
18459 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18460 when a (possibly-narrower) signed value would do just as well.
18461 We prefer using signed arithmetic, to avoid comparison confusion.
18463 * alloc.c: Catch some string size overflows that we were missing.
18464 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18465 for convenience in STRING_BYTES_MAX.
18466 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18467 The definition here is exact; the one in lisp.h was approximate.
18468 (allocate_string_data): Check for string overflow. This catches
18469 some instances we weren't catching before. Also, it catches
18470 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18471 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18472 and ptrdiff_t and EMACS_INT are both 64 bits.
18474 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18475 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18476 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18478 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18480 * alloc.c (Fmake_string): Check for out-of-range init.
18482 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18484 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18486 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18488 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18489 xg_get_default_scrollbar_width.
18491 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18492 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18493 (style_changed_cb): Call update_theme_scrollbar_width and call
18494 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18495 all frames (Bug#8505).
18496 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18497 Call gtk_window_set_resizable if HAVE_GTK3.
18498 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18499 and height if HAVE_GTK3 (Bug#8505).
18500 (scroll_bar_width_for_theme): New variable.
18501 (update_theme_scrollbar_width): New function.
18502 (xg_get_default_scrollbar_width): Move code to
18503 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18504 (xg_initialize): Call update_theme_scrollbar_width.
18506 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18508 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18510 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18512 * frame.c (make_frame): Call other_buffer_safely instead of
18515 * window.c (temp_output_buffer_show): Call display_buffer with
18516 second argument Vtemp_buffer_show_specifiers and reset latter
18517 immediately after the call.
18518 (Vtemp_buffer_show_specifiers): New variable.
18519 (auto_window_vscroll_p, next_screen_context_lines)
18520 (Vscroll_preserve_screen_position): Remove leading asterisks from
18523 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18525 Fix minor problems found by GCC 4.6.0 static checking.
18526 * buffer.c (Qclone_number): Remove for now, as it's unused.
18527 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18528 (record_buffer): Remove unused local.
18529 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18530 (set_frame_buffer_list): Remove; unused.
18531 * frame.h (other_visible_frames): Remove decl.
18532 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18533 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18534 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18536 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18537 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18538 Define only if HAVE_GPM.
18539 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18540 (update_hints_inhibit): Remove; never set. All uses removed.
18541 * widgetprv.h (emacsFrameClassRec): Remove decl.
18542 * window.c (delete_deletable_window): Now returns void, since it
18543 wasn't returning anything.
18544 (compare_window_configurations): Remove unused locals.
18545 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18546 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18547 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18548 the same widths as pointers. This follows up on the 2011-05-06 patch.
18549 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18550 * xterm.h: Likewise.
18551 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

18556 (LISP_H): Add lib/intprops.h.
18558 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18560 * image.c (gif_load): Add animation frame delay to the metadata.
18561 (syms_of_image): Use DEFSYM. New symbol `delay'.
18563 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18565 * window.c (delete_deletable_window): Re-add.
18566 (Fset_window_configuration): Rewrite to handle dead buffers and
18567 consequently deletable windows.
18568 (window_tree, Fwindow_tree): Remove. Supply functionality in
18570 (compare_window_configurations): Simplify code.
18572 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18574 * image.c (imagemagick_load_image): Fix type mismatch.
18575 (Fimagemagick_types): Likewise.
18577 * window.h (replace_buffer_in_windows): Declare.
18579 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18581 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18582 Qclone_number. Remove external declaration of Qdelete_window.
18583 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18585 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18586 Run Qbuffer_list_update_hook if allowed.
18587 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18588 buffer list implementation.
18589 (other_buffer_safely): New function.
18590 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18591 calls to replace_buffer_in_windows and
18592 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18594 (record_buffer): Inhibit quitting and rewrite using quittable
18595 functions. Run Qbuffer_list_update_hook if allowed.
18596 (Frecord_buffer, Funrecord_buffer): New functions.
18597 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18598 Move switch-to-buffer to window.el.
18599 (bury-buffer): Move to window.el.
18600 (Vbuffer_list_update_hook): New variable.
18602 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18605 * window.h (resize_frame_windows): Move up in code.
18606 (Fwindow_frame): Remove EXFUN.
18607 (replace_buffer_in_all_windows): Remove prototype.
18608 (replace_buffer_in_windows_safely): Add prototype.
18610 * window.c: Declare Qdelete_window static again. Move down
18611 declaration of select_count.
18612 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18613 (Fother_window): Move to window.el.
18614 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18615 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18616 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18618 (replace_buffer_in_windows): Implement by calling
18619 Qreplace_buffer_in_windows.
18620 (replace_buffer_in_all_windows): Remove with some functionality
18621 moved into replace_buffer_in_windows_safely.
18622 (replace_buffer_in_windows_safely): New function.
18623 (select_window_norecord, select_frame_norecord): Move in front
18624 of run_window_configuration_change_hook. Remove now obsolete
18626 (Fset_window_buffer): Rewrite doc-string.
18627 Call Qrecord_window_buffer.
18628 (keys_of_window): Move binding for other-window to window.el.
18630 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18632 * dispextern.h (struct image): Replace data member, whose int_val
18633 and ptr_val fields were not used by anything, with a single
18636 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18637 (gif_clear_image, gif_load, imagemagick_load_image)
18638 (gs_clear_image, gs_load): Callers changed.

19104 Declare prototypes.
19105 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19108 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19110 Malloc failure behavior now depends on size of allocation.
19111 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19112 * lisp.h: Change signatures accordingly.
19113 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19114 All callers changed. (Bug#8762)
19116 * gnutls.c: Use Emacs's memory allocators.
19117 Without this change, the gnutls library would invoke malloc etc.
19118 directly, which causes problems on non-SYNC_INPUT hosts, and which
19119 runs afoul of improving memory_full behavior. (Bug#8761)
19120 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19121 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19122 xfree instead of the default malloc, realloc, free.
19123 (Fgnutls_boot): No need to check for memory allocation failure,
19124 since xmalloc does that for us.
19126 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19127 * category.c (hash_get_category_set):
19128 * ccl.c (ccl_driver):
19129 * charset.c (Fdefine_charset_internal):
19130 * charset.h (struct charset.hash_index):
19131 * composite.c (get_composition_id, gstring_lookup_cache)
19132 (composition_gstring_put_cache):
19133 * composite.h (struct composition.hash_index):
19134 * dispextern.h (struct image.hash):
19135 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19136 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

19139 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19140 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19141 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19142 * image.c (make_image, search_image_cache, lookup_image)
19143 (xpm_put_color_table_h):
19144 * lisp.h (struct Lisp_Hash_Table):
19145 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19146 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19147 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19148 * alloc.c (allocate_vectorlike):
19149 Check for overflow in vector size calculations.
19150 * ccl.c (ccl_driver):
19151 Check for overflow when converting EMACS_INT to int.
19152 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19153 need to be updated by these changes.
19154 * fns.c (make_hash_table, maybe_resize_hash_table):
19155 Check for integer overflow with large hash tables.
19156 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19157 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19158 (SXHASH_REDUCE): New macro.
19159 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19160 Use it instead of discarding useful hash info with large hash values.
19161 (sxhash_float): New function.
19162 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19163 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19164 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19165 Rewrite to use FIXNUM_BITS, as this simplifies things.
19166 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19167 Adjust signatures to match updated version of code.
19168 (consing_since_gc): Now EMACS_INT, since a single hash table can
19169 use more than INT_MAX bytes.
19171 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19173 Make it possible to build with GCC-4.6+ -O2 -flto.
19175 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19177 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19179 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19180 Call minibuffer-inactive-mode.
19182 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19184 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19185 Update dependencies.
19187 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19189 * data.c (init_data): Remove code for UTS, this system is not
19192 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19194 Don't force ./temacs to start in terminal mode.
19196 * frame.c (make_initial_frame): Initialize faces in all cases, not
19197 only when CANNOT_DUMP is defined.
19198 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19200 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19202 * dispnew.c (add_window_display_history): Use const for the string
19203 pointer. Remove declaration, not needed.
19205 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19207 Use 'inline', not 'INLINE'.
19208 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19209 * alloc.c, fontset.c (INLINE): Remove.
19210 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19211 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19212 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19213 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19214 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19216 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19218 Make it possible to run ./temacs.
19220 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19221 syms_of_callproc does the same thing. Remove test for
19222 "initialized", do it in the caller.
19223 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19225 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19227 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19228 (read_minibuf): Use get_minibuffer.
19229 (syms_of_minibuf): Use DEFSYM.
19230 (Qmetadata): New var.
19231 * data.c (Qbuffer): Don't make it static.
19232 (syms_of_data): Use DEFSYM.
19234 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19236 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19237 (CCL_CODE_MIN): New macro.
19239 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19241 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19243 * eval.c (Qdebug): Now static.
19244 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19245 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19246 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19248 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19250 * image.c: Various fixes to ImageMagick code comments.
19251 (Fimagemagick_types): Doc fix.
19253 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19255 Minor fixes prompted by GCC 4.6.0 warnings.
19257 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19259 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19260 (x_clipboard_manager_save_all): Move extern decl to ...
19261 * xterm.h: ... here, so that it can be checked for consistency.
19263 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19265 * xselect.c (x_clipboard_manager_save_frame)
19266 (x_clipboard_manager_save_all): New functions.
19267 (Fx_clipboard_manager_save): Lisp function deleted.
19269 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19270 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19272 * xterm.h: Update prototype.
19274 2011-05-28 William Xu <william.xwl@gmail.com>
19276 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19277 exiting (Bug#8239).
19279 2011-05-28 Jim Meyering <meyering@redhat.com>
19281 Avoid a sign-extension bug in crypto_hash_function.
19282 * fns.c (to_uchar): Define.
19283 (crypto_hash_function): Use it to convert some newly-signed
19284 variables to unsigned, to avoid sign-extension bugs. For example,
19285 without this change, (md5 "truc") would evaluate to
19286 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19287 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19288 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19290 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19292 Integer overflow fixes.
19294 * dbusbind.c: Serial number integer overflow fixes.
19295 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19296 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19297 to hold a serial number that is too large for a fixnum.
19298 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19299 Check for serial numbers out of range. Decode any serial number
19300 that was so large that it became a float. (Bug#8722)
19302 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19303 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19304 Use XFASTINT rather than XUINT when numbers are nonnegative.
19305 (xd_append_arg, Fdbus_method_return_internal):
19306 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19307 arguments, check that Lisp number is nonnegative, rather than
19308 silently wrapping negative numbers around. (Bug#8722)
19309 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19312 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19314 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19316 ccl: Add integer overflow checks.
19317 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19318 (IN_INT_RANGE): New macros.
19319 (ccl_driver): Use them to check for integer overflow when
19320 decoding a CCL program. Many of the new checks are whether XINT (x)
19321 fits in int; it doesn't always, on 64-bit hosts. The new version
19322 doesn't catch all possible integer overflows, but it's an
19323 improvement. (Bug#8719)
19325 * alloc.c (make_event_array): Use XINT, not XUINT.
19326 There's no need for unsigned here.
19328 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19329 This follows up to the 2011-05-06 change that substituted uintptr_t
19330 for EMACS_INT. This case wasn't caught back then.
19332 Rework Fformat to avoid integer overflow issues.
19333 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19334 now (part of C89). Include <verify.h>.
19335 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19336 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19337 (Fformat): Avoid the prepass trying to compute sizes; it was only
19338 approximate and thus did not catch overflow reliably. Instead, walk
19339 through the format just once, formatting and computing sizes as we go,
19340 checking for integer overflow at every step, and allocating a larger
19341 buffer as needed. Keep track separately whether the format is
19342 multibyte. Keep only the most-recently calculated precision, rather
19343 than them all. Record whether each argument has been converted to
19344 string. Use EMACS_INT, not int, for byte and char and arg counts.
19345 Support field widths and precisions larger than INT_MAX. Avoid
19346 sprintf's undefined behavior with conversion specifications such as %#d
19347 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19348 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19349 formatting out-of-range floating point numbers with int
19350 formats. (Bug#8668)
19352 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19354 * data.c: Avoid integer truncation in expressions involving floats.
19355 * data.c: Include <intprops.h>.
19356 (arith_driver): When there's an integer overflow in an expression
19357 involving floating point, convert the integers to floating point
19358 so that the resulting value does not suffer from catastrophic
19359 integer truncation. For example, on a 64-bit host (* 4
19360 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19361 Do not rely on undefined behavior after integer overflow.
19363 merge count_size_as_multibyte, parse_str_to_multibyte
19364 * character.c, character.h (count_size_as_multibyte):
19365 Rename from parse_str_to_multibyte; all uses changed.
19366 Check for integer overflow.
19367 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19368 since it's now a duplicate of the other. This is more of
19369 a character than a buffer op, so better that it's in character.c.
19370 * fns.c, print.c: Adjust to above changes.
19372 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19374 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19376 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19378 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19379 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19380 (x_clipboard_manager_save): Now static.
19381 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19383 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19384 (crypto_hash_function): Now static.
19385 Fix pointer signedness problems. Avoid unnecessary initializations.
19387 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19389 * termhooks.h (Vselection_alist): Make it terminal-local.
19391 * terminal.c (create_terminal): Initialize it.
19393 * xselect.c: Support for clipboard managers.
19394 (Vselection_alist): Move to termhooks.h as terminal-local var.
19395 (LOCAL_SELECTION): New macro.
19396 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19397 (symbol_to_x_atom): Remove gratuitous arg.
19398 (x_handle_selection_request, lisp_data_to_selection_data)
19399 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19400 (x_own_selection, x_get_local_selection, x_convert_selection):
19401 New arg, specifying work frame. Use terminal-local Vselection_alist.
19402 (some_frame_on_display): Delete unused function.
19403 (Fx_own_selection_internal, Fx_get_selection_internal)
19404 (Fx_disown_selection_internal, Fx_selection_owner_p)
19405 (Fx_selection_exists_p): New optional frame arg.
19406 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19407 (x_handle_selection_clear): Don't treat other terminals with the
19408 same keyboard specially. Use the terminal-local Vselection_alist.
19409 (x_clear_frame_selections): Use Frun_hook_with_args.
19411 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19413 * xterm.h: Add support for those atoms.
19415 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19417 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19418 (converted_selections, conversion_fail_tag): New global variables.
19419 (x_selection_request_lisp_error): Free the above.
19420 (x_get_local_selection): Remove unnecessary code.
19421 (x_reply_selection_request): Args changed; handle arbitrary array
19422 of converted selections stored in converted_selections.
19423 Separate the XChangeProperty and SelectionNotify steps.
19424 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19425 (x_convert_selection): New function.
19426 (x_handle_selection_event): Simplify.
19427 (x_get_foreign_selection): Don't ignore incoming requests while
19428 waiting for an answer; this will fail when we implement
19429 SAVE_TARGETS, and seems unnecessary anyway.
19430 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19431 (Vx_sent_selection_functions): Doc fix.
19433 2011-05-26 Leo Liu <sdl.web@gmail.com>
19435 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19437 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19439 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19441 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19442 for fringe update if it has periodic bitmap.
19443 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19444 and fringe_bitmap_periodic_p.
19446 * fringe.c (get_fringe_bitmap_data): New function.
19447 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19448 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19449 row. Mark glyph row for fringe update if periodicity changed.
19451 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19452 for fringe update unless it has periodic bitmap.
19454 2011-05-25 Kenichi Handa <handa@m17n.org>
19456 * xdisp.c (get_next_display_element): Set correct it->face_id for

19471 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19472 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19473 Remove macros that are defined and never used.
19474 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19476 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19478 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19479 (Fx_get_selection_internal): Minor cleanup.
19480 (Fx_own_selection_internal): Rename arguments for consistency with
19483 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

19505 report_file_error introduced by the change from 2011-05-07.
19507 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19509 * systime.h (Time): Define only if emacs is defined.
19510 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19511 where the include path doesn't have X11/X.h by default. See
19512 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19514 2011-05-20 Kenichi Handa <handa@m17n.org>
19516 * composite.c (find_automatic_composition): Fix previous change.
19518 2011-05-20 Glenn Morris <rgm@gnu.org>

19529 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19530 (lisp): Set the order to that of loadup.el.
19531 (shortlisp): Make it a copy of $lisp.
19532 (SOME_MACHINE_LISP): Remove.
19533 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19534 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19536 2011-05-18 Kenichi Handa <handa@m17n.org>
19538 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19539 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19540 (find_automatic_composition): Mostly rewrite for efficiency.
19542 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19544 * makefile.w32-in: Update dependencies.
19546 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19548 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19549 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19551 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19553 Fix some integer overflow issues, such as string length overflow.
19555 * insdel.c (count_size_as_multibyte): Check for string overflow.
19557 * character.c (lisp_string_width): Check for string overflow.
19558 Use EMACS_INT, not int, for string indexes and lengths; in
19559 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19560 the resulting string length overflows an EMACS_INT; instead,
19561 report a string overflow if no precision given. When checking for
19562 precision exhaustion, use a check that cannot possibly have
19563 integer overflow. (Bug#8675)
19564 * character.h (lisp_string_width): Adjust to new signature.
19566 * alloc.c (string_overflow): New function.
19567 (Fmake_string): Use it. This doesn't change behavior, but saves
19568 a few bytes and will simplify future changes.
19569 * character.c (string_escape_byte8): Likewise.
19570 * lisp.h (string_overflow): New decl.
19572 Fixups, following up to the user-interface timestamp change.
19573 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19574 for UI timestamps, instead of unsigned long.
19575 * msdos.c (mouse_get_pos): Likewise.
19576 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19577 * w32gui.h (Time): Define by including "systime.h" rather than by
19578 declaring it ourselves. (Bug#8664)
19580 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19581 * image.c (clear_image_cache): Likewise.
19583 * term.c (term_mouse_position): Don't assume time_t wraparound.
19585 Be more systematic about user-interface timestamps.
19586 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19587 and sometimes 'EMACS_UINT', to represent these timestamps.
19588 This change causes it to use 'Time' uniformly, as that's what X uses.
19589 This makes the code easier to follow, and makes it easier to catch
19590 integer overflow bugs such as Bug#8664.
19591 * frame.c (Fmouse_position, Fmouse_pixel_position):
19592 Use Time, not unsigned long, for user-interface timestamps.
19593 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19594 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19595 * keyboard.h (last_event_timestamp): Likewise.
19596 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19597 * menu.h (xmenu_show): Likewise.
19598 * term.c (term_mouse_position): Likewise.
19599 * termhooks.h (struct input_event.timestamp): Likewise.
19600 (struct terminal.mouse_position_hook): Likewise.
19601 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19602 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19603 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19604 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19605 what it was before.
19606 * menu.h, termhooks.h: Include "systime.h", for Time.
19608 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19609 Don't assume that the difference between two unsigned long values
19610 can fit into an integer. At this point, we know button_down_time
19611 <= event->timestamp, so the difference must be nonnegative, so
19612 there's no need to cast the result if double-click-time is
19613 nonnegative, as it should be; check that it's nonnegative, just in
19614 case. This bug is triggered when events are more than 2**31 ms
19615 apart (about 25 days). (Bug#8664)
19617 * xselect.c (last_event_timestamp): Remove duplicate decl.
19618 (x_own_selection): Remove needless cast to unsigned long.
19620 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19621 that always fit in int. Use a sentinel instead of a counter, to
19622 avoid a temp and to allay GCC's concerns about possible int overflow.
19623 * frame.h (struct frame): Use int for menu_bar_items_used
19624 instead of EMACS_INT, since it always fits in int.
19626 * menu.c (grow_menu_items): Check for int overflow.
19628 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19630 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19631 Before, the code was not consistent. These values cannot exceed
19632 2**31 - 1 so there's no need to make them unsigned.
19633 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19634 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19635 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19637 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19639 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19640 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19641 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19642 presumably because the widths might not match.
19644 * window.c (size_window): Avoid needless test at loop start.
19646 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19648 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19650 2011-05-12 Drew Adams <drew.adams@oracle.com>
19652 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19654 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19656 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19657 `width' to `bar_area_x' and `bar_area_width', respectively.
19658 (x_scroll_run): Take account of fringe background extension.
19660 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19661 Rename local vars `left' and `width' to `bar_area_x' and
19662 `bar_area_width', respectively.
19663 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19664 background extension.
19666 2011-05-10 Jim Meyering <meyering@redhat.com>
19668 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19670 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19672 * image.c (Finit_image_library): Return t for built-in image types,
19673 like pbm and xbm. (Bug#8640)
19675 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19677 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19679 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19681 * w32console.c (Fset_screen_color): Doc fix.
19682 (Fget_screen_color): New function.
19683 (syms_of_ntterm): Defsubr it.
19685 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19686 unlink the temporary file if Fcall_process didn't create it in the
19688 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19689 child process will be redirected to a file specified with `:file'.
19690 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19691 cue to call_process_cleanup not to close that handle.
19693 2011-05-07 Ben Key <bkey76@gmail.com>
19695 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19696 one of two shell specific rules, either bootstrap-temacs-CMD or
19697 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19698 to the previous implementation of the bootstrap-temacs rule.
19699 The bootstrap-temacs-CMD rule is similar to the previous
19700 implementation of the bootstrap-temacs rule except that it
19701 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19704 These changes, along with some changes to nt/configure.bat,
19705 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19706 earlier fix to add support for --cflags and --ldflags options
19707 that include quotes so that it works whether make uses cmd or
19710 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19712 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19713 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19715 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19716 a string. Handle both cases.
19717 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19718 (Fdbus_register_method): Use Qinvalid_function.
19720 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19722 * makefile.w32-in: Update dependencies.
19723 (LISP_H): Add inttypes.h and stdin.h.
19724 (PROCESS_H): Add unistd.h.
19726 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19728 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19729 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19731 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19733 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19735 * term.c (vfatal): Remove stray call to va_end.
19736 It's not needed and the C Standard doesn't allow it here anyway.
19738 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19739 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19741 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19744 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19746 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19748 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19750 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19752 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19754 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19755 * charset.c (Fdefine_charset_internal): Don't initialize
19756 charset.code_space[15]. The value was garbage, on hosts with
19757 32-bit int (Bug#8600).
19759 * lread.c (read_integer): Be more consistent with string-to-number.
19760 Use string_to_number to do the actual conversion; this avoids
19761 rounding errors and fixes some other screwups. Without this fix,
19762 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19763 (digit_to_number): Move earlier, for benefit of read_integer.
19764 Return -1 if the digit is out of range for the base, -2 if it is
19765 not a digit in any supported base. (Bug#8602)
19767 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19769 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19770 to match comment at start of function. This also removes a
19771 GCC warning about overflow in a 32+64-bit port.
19773 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19775 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19776 Reported by Stefan Monnier in
19777 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19778 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19779 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19781 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19782 (EMACS_UINTPTR): Likewise, with uintptr_t.
19784 * lisp.h: Prefer 64-bit EMACS_INT if available.
19785 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19786 on 32-bit hosts that have 64-bit int, so that they can access
19788 However, temporarily disable this change unless the temporary
19789 symbol WIDE_EMACS_INT is defined.
19791 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19793 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19794 This removes an assumption that EMACS_INT and long are the same
19795 width as pointers. The assumption is true for Emacs porting targets
19796 now, but we want to make other targets possible.
19797 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19798 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19799 In the rest of the code, change types of integers that hold casted
19800 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19801 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19802 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19803 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19804 No need to cast type when ORing.
19805 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19806 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19807 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19808 assume EMACS_INT is the same width as char *.
19809 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19810 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19811 Remove no-longer-needed casts.
19812 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19813 (xg_tool_bar_help_callback, xg_make_tool_item):
19814 Use EMACS_INTPTR to hold an integer
19815 that will be cast to void *; this can avoid a GCC warning
19816 if EMACS_INT is not the same width as void *.
19817 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19818 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19819 (current_message_1, set_message_1):
19820 Use a local to convert to proper width without a cast.
19821 * xmenu.c (dialog_selection_callback): Likewise.
19823 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19824 Also, don't assume VALBITS / RAND_BITS is less than 5,
19825 and don't rely on undefined behavior when shifting a 1 left into
19827 * lisp.h (get_random): Change signature to match.
19829 * lread.c (hash_string): Use size_t, not int, for hash computation.
19830 Normally we prefer signed values; but hashing is special, because
19831 it's better to use unsigned division on hash table sizes so that
19832 the remainder is nonnegative. Also, size_t is the natural width
19833 for hashing into memory. The previous code used 'int', which doesn't
19834 retain enough info to hash well into very large tables.
19835 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19837 * dbusbind.c: Don't possibly lose pointer info when converting.
19838 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19839 Use XPNTR rather than XHASH, so that the high-order bits of
19840 the pointer aren't lost when converting through void *.
19842 * eval.c (Fautoload): Don't double-shift a pointer.
19844 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19846 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19848 * gnutls.c (DEF_GNUTLS_FN):
19849 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19851 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19853 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19856 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19858 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19859 New version that can reserve upto 2GB of heap space.
19861 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19863 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19865 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19867 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19868 `gnutls_certificate_set_x509_key_file'.
19870 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19872 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19873 Update dependencies.
19875 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19877 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19878 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19879 Remove unused parameter `fildes'.
19880 * process.c (read_process_output, send_process): Don't pass it.
19882 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19884 Fix previous change: the library cache is defined in w32.c.
19885 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19886 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19888 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19890 Implement dynamic loading of GnuTLS on Windows.
19892 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19893 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19894 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19897 * gnutls.c (Qgnutls_dll): Define.
19898 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19899 (gnutls_*): Declare function pointers.
19900 (init_gnutls_functions): New function to initialize function pointers.
19901 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19902 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19903 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19904 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19905 (emacs_gnutls_write, emacs_gnutls_read)
19906 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19907 (Fgnutls_available_p): New function.
19908 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19909 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19910 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19912 * image.c: Include w32.h.
19913 (Vimage_type_cache): Delete.
19914 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19915 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19916 (w32_delayed_load): Move to w32.c.
19918 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19920 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19921 (w32_delayed_load): Move from image.c. When loading a library, record
19922 its filename in the :loaded-from property of the library id.
19923 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19924 Initialize and staticpro them.
19925 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19927 * process.c: Include lisp.h before w32.h, not after.
19928 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19929 instead of gnutls_record_check_pending.
19931 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19933 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19935 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19936 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19939 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19941 * xterm.c (x_set_frame_alpha): Do not set property on anything
19942 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19944 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19946 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19948 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19950 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19951 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19981 rather than `XVECTOR (FOO)->size'.
19983 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19984 inttypes.h, as a gnulib replacement is used if it not available in

19997 space for up to 2 characters produced in a loop.
19998 (decode_coding_iso_2022): Abort if there isn't enough place in
19999 charbuf for the composition carryover bytes.
20001 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20003 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20004 aborting when %lld or %lll format is passed.
20005 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20006 %llo or %llx format is passed. (Bug#8545)
20008 * window.c (window_scroll_line_based): Use a marker instead of
20009 simple variables to record original value of point. (Bug#7952)
20011 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20012 produced by %s or %c overflows available buffer space. (Bug#8545)
20014 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20016 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20017 (SIZE_MAX): Move defn after all includes, as they might #define it.
20019 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

20026 (command_loop_1): Run `delayed-warnings-hook'
20027 if Vdelayed_warnings_list is non-nil.
20028 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20029 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20031 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20033 * doprnt.c (doprnt): Don't return value smaller than the buffer
20034 size if the message was truncated. (Bug#8545).

20043 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20045 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20047 * makefile.w32-in: Update dependencies.
20049 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20051 Improve `doprnt' and its usage. (Bug#8545)
20052 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20053 `format_end'. Remove support for %l as a conversion specifier.
20054 Don't use xrealloc. Improve diagnostics when the %l size modifier
20055 is used. Update the commentary.
20057 * eval.c (verror): Simplify calculation of size_t.
20059 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20062 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20064 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20067 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20069 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20070 This makes this file independent of the recent pseudovector change.
20072 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20074 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20076 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20077 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20078 Remove unused local.
20079 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20081 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20082 GCC 4.6.0 optimizes based on type-based alias analysis.
20083 For example, if b is of type struct buffer * and v of type struct
20084 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20085 != &v->size, and therefore "v->size = 1; b->size = 2; return
20086 v->size;" must therefore return 1. This assumption is incorrect
20087 for Emacs, since it type-puns struct Lisp_Vector * with many other
20088 types. To fix this problem, this patch adds a new type struct
20089 vectorlike_header that documents the constraints on layout of vectors
20090 and pseudovectors, and helps optimizing compilers not get fooled
20091 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20092 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20093 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20095 (XSETPVECTYPE): Rewrite in terms of new macro.
20096 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20097 This is a bit clearer, and further avoids the possibility of
20098 undesirable aliasing.
20099 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20100 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20101 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20102 since Lisp_Subr is a special case (no "next" field).
20103 (ASIZE): Now uses header.size rather than size.
20104 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20105 to avoid the hassle of writing XVECTOR (foo)->header.size.
20106 (struct vectorlike_header): New type.
20107 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20108 object, to help avoid aliasing.
20109 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20110 (SUBRP): Likewise, since Lisp_Subr is a special case.
20111 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20112 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20113 (struct Lisp_Hash_Table): Combine first two members into a single
20114 struct vectorlike_header member. All uses of "size" and "next" members
20115 changed to be "header.size" and "header.next".
20116 * buffer.h (struct buffer): Likewise.
20117 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20118 * frame.h (struct frame): Likewise.
20119 * process.h (struct Lisp_Process): Likewise.
20120 * termhooks.h (struct terminal): Likewise.
20121 * window.c (struct save_window_data, struct saved_window): Likewise.
20122 * window.h (struct window): Likewise.
20123 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20124 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20125 * buffer.c (init_buffer_once): Likewise.
20126 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20128 * process.c (Fformat_network_address): Use local var for size,
20131 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20133 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20134 * data.c (atof): Remove decl; no longer used or needed.
20135 (digit_to_number): Move to lread.c.
20136 (Fstring_to_number): Use new string_to_number function, to be
20137 consistent with how the Lisp reader treats infinities and NaNs.
20138 Do not assume that floating-point numbers represent EMACS_INT
20139 without losing information; this is not true on most 64-bit hosts.
20140 Avoid double-rounding errors, by insisting on integers when
20141 parsing non-base-10 numbers, as the documentation specifies.
20142 * lisp.h (string_to_number): New decl, replacing ...
20143 (isfloat_string): Remove.
20144 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20145 (read1): Do not accept +. and -. as integers; this
20146 appears to have been a coding error. Similarly, do not accept
20147 strings like +-1e0 as floating point numbers. Do not report
20148 overflow for integer overflows unless the base is not 10 which
20149 means we have no simple and reliable way to continue.
20150 Break out the floating-point parsing into a new
20151 function string_to_number, so that Fstring_to_number parses
20152 floating point numbers consistently with the Lisp reader.
20153 (digit_to_number): Move here from data.c. Make it static inline.
20154 (E_CHAR, EXP_INT): Remove, replacing with ...
20155 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20156 (string_to_number): New function, replacing isfloat_string.
20157 This function checks for valid syntax and produces the resulting
20158 Lisp float number too. Rework it so that string-to-number
20159 no longer mishandles examples like "1.0e+". Use strtoumax,
20160 so that overflow for non-base-10 numbers is reported only when
20161 there's no portable and simple way to convert to floating point.
20163 * textprop.c (set_text_properties_1): Rewrite for clarity,
20164 and to avoid GCC warning about integer overflow.
20166 * intervals.h (struct interval): Use EMACS_INT for members
20167 where EMACS_UINT might cause problems. See
20168 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20169 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20170 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20172 (offset_intervals): Tell GCC not to worry about length overflow
20173 when negating a negative length.
20175 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20176 (overrun_check_free): Likewise.
20178 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20179 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20182 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20183 (gnutls_make_error): Rename local to avoid shadowing.
20184 (gnutls_emacs_global_deinit): ifdef out; not used.
20185 (Fgnutls_boot): Use const for pointer to readonly storage.
20186 Comment out unused local. Fix pointer signedness problems.
20188 * lread.c (openp): Don't stuff size_t into an 'int'.
20189 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20190 about possible signed overflow.
20192 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20193 (GDK_KEY_g): Don't define if already defined.
20194 (xg_prepare_tooltip): Avoid pointer signedness problem.
20195 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20197 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20198 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20200 * xfns.c (Fx_window_property): Simplify a bit,
20201 to make a bit faster and to avoid GCC 4.6.0 warning.
20202 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20204 * fns.c (internal_equal): Don't assume size_t fits in int.
20206 * alloc.c (compact_small_strings): Tighten assertion a little.
20208 Replace pEd with more-general pI, and fix some printf arg casts.
20209 * lisp.h (pI): New macro, generalizing old pEd macro to other
20210 conversion specifiers. For example, use "...%"pI"d..." rather
20211 than "...%"pEd"...".
20212 (pEd): Remove. All uses replaced with similar uses of pI.
20213 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20214 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20215 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20216 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20217 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20218 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20219 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20221 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20222 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20223 * print.c (safe_debug_print, print_object): Likewise.
20224 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20226 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20227 avoiding the 0 flag, which is not portable.
20228 * process.c (Fmake_network_process): Use pI to avoid cast.
20229 * region-cache.c (pp_cache): Likewise.
20230 * xdisp.c (decode_mode_spec): Likewise.
20231 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20232 behavior on 64-bit hosts with printf arg.
20233 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20234 (x_stop_queuing_selection_requests): Likewise.
20235 (x_get_window_property): Don't truncate byte count to an 'int'
20238 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20239 here, since it parses constructs like leading '-' and spaces,
20240 which are not wanted; and it overflows with large numbers.
20241 Instead, simply match F[0-9]+, which is what is wanted anyway.
20243 * alloc.c: Remove unportable assumptions about struct layout.
20244 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20245 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20246 (allocate_vectorlike, make_pure_vector): Use the new macros,
20247 plus offsetof, to remove unportable assumptions about struct layout.
20248 These assumptions hold on all porting targets that I know of, but
20249 they are not guaranteed, they're easy to remove, and removing them
20250 makes further changes easier.
20252 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20253 This doesn't fix a bug but makes the code clearer.
20254 (string_overrun_cookie): Now const. Use initializers that
20255 don't formally overflow signed char, to avoid warnings.
20256 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20257 can cause Emacs to crash when string overrun checking is enabled.
20258 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20259 multiple of sizeof (EMACS_INT); it need not be, if
20260 alignof(EMACS_INT) < sizeof (EMACS_INT).
20261 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20263 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20265 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20267 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20269 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20270 supposed to be handshaking. (Bug#8556)
20271 Reported by Paul Eggert <eggert@cs.ucla.edu>.

20276 * eval.c (Qdebug): Restore global linkage.
20277 * keyboard.c (debug-on-event): New variable.
20278 (handle_user_signal): Break into debugger when debug-on-event
20279 matches the current signal symbol.
20281 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20283 * alloc.c (check_sblock, check_string_bytes)
20284 (check_string_free_list): Convert to standard C.
20286 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20288 * w32.c (emacs_gnutls_push): Fix typo.
20290 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20292 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20293 "cast to pointer from integer of different size".
20295 Improve doprnt and its use in verror. (Bug#8545)
20296 * doprnt.c (doprnt): Document the set of format control sequences
20297 supported by the function. Use SAFE_ALLOCA instead of always
20300 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20301 is one byte too soon. Don't use xrealloc; instead xfree and
20304 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20306 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20309 * gnutls.c: Renamed global_initialized to
20310 gnutls_global_initialized. Added internals for the
20311 :verify-hostname-error, :verify-error, and :verify-flags
20312 parameters of `gnutls-boot' and documented those parameters in the
20313 docstring. Start callback support.
20314 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20315 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20316 on error. Return error code.
20317 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20318 (emacs_gnutls_read): Likewise.
20319 (Fgnutls_boot): Return handshake error code.
20320 (emacs_gnutls_handle_error): New function.
20321 (wsaerror_to_errno): Likewise.

20324 (emacs_gnutls_push): Likewise.
20326 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
20327 (emacs_gnutls_push): Likewise.
20329 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
20331 * process.c (wait_reading_process_output): Check if GnuTLS
20332 buffered some data internally if no FDs are set for TLS
20335 * makefile.w32-in (OBJ2): Add gnutls.$(O).
20336 (LIBS): Link to USER_LIBS.

20341 * xdisp.c (handle_single_display_spec): Rename the
20342 display_replaced_before_p argument into display_replaced_p, to
20343 make it consistent with the commentary. Fix typos in the
20346 * textprop.c (syms_of_textprop): Remove dead code.
20347 (copy_text_properties): Delete obsolete commentary about an
20348 interface that was deleted long ago. Fix typos in the description

20352 to changes in oldXMenu/XMenu.h from 2011-04-16.
20353 <menu_help_message, prev_menu_help_message>: Constify.
20354 (IT_menu_make_room): menu->help_text is now `const char **';
20357 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
20358 to changes in oldXMenu/XMenu.h from 2011-04-16.
20359 (struct XMenu): Declare `help_text' `const char **'.

20370 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
20372 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
20375 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
20376 changes in globals.h immediately force recompilation.
20377 (TAGS): Depend on $(CURDIR)/m/intel386.h and
20378 $(CURDIR)/s/ms-w32.h.
20379 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
20381 * character.c (Fchar_direction): Function deleted.
20382 (syms_of_character): Don't defsubr it.
20383 <char-direction-table>: Deleted.
20385 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20387 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
20388 * doprnt.c: Include limits.h.
20389 (SIZE_MAX): New macro.
20390 (doprnt): Return a size_t value. 2nd arg is now size_t.

20621 ns_descriptor_to_entity that were caused by using free to
20622 deallocate memory blocks that were allocated by xmalloc (via

20644 * process.c (send_process): Adjust to the new signatures of
20645 emacs_write and emacs_gnutls_write. Do not attempt to store

20869 * editfns.c, lisp.h (get_operating_system_release): Remove.
20870 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20871 worth the hassle of breaking this out.
20873 * xterm.c: Make symbols static if they're not exported.
20874 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

20986 * atimer.h (run_all_atimers): Remove; not exported.
20988 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20989 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20990 was inaccessible from Lisp.
20991 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20992 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20994 alloc.c: Import and export fewer symbols, and remove unused items.
20995 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20997 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20998 it's not optimized away by whole-program optimization.

21011 (mark_backtrace): Define only if BYTE_MARK_STACK.
21012 * xdisp.c (message_enable_multibyte): Now static.
21014 Declare Lisp_Object Q* variables to be 'static' if not exported.
21015 This makes it easier for human readers (and static analyzers)
21016 to see whether these variables are used from other modules.
21017 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21018 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

21028 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21030 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21032 Make Emacs functions such as Fatom 'static' by default.
21033 This makes it easier for human readers (and static analyzers)
21034 to see whether these functions can be called from other modules.
21035 DEFUN now defines a static function. To make the function external
21036 so that it can be used in other C modules, use the new macro DEFUE.
21037 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21038 (Finit_image_library):
21039 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21040 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21041 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21042 Remove decls, since these functions are now static.
21043 (Funintern, Fget_internal_run_time): New decls, since these functions
21044 were already external.
21046 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

21054 Mark functions with DEFUE instead of DEFUN,
21055 if they are used in other modules.
21056 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21057 decls for now-static functions.
21058 * buffer.h (Fdelete_overlay): Remove decl.

21068 * image.c (Finit_image_library): New forward static decl.
21069 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

21094 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21096 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21097 when at ZV. (Bug#8487)
21099 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21101 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21107 * xsettings.c (read_and_apply_settings): Likewise.
21109 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21110 (overrun_check_free): Protoize.
21112 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21114 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21115 since callers should never pass a negative size.
21116 Change the signature to match that of plain 'read' and 'write'; see
21117 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21118 * lisp.h: Update prototypes of emacs_write and emacs_read.
21120 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21122 * xdisp.c (redisplay_window): Don't try to determine the character
21123 position of the scroll margin if the window start point w->startp
21124 is outside the buffer's accessible region. (Bug#8468)
21126 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21128 Fix write-region and its subroutines for buffers > 2GB.
21129 * fileio.c (a_write, e_write): Modify declaration of arguments and
21130 local variables to support buffers larger than 2GB.
21131 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21133 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21134 argument, local variables, and return value.
21136 * lisp.h: Update prototypes of emacs_write and emacs_read.
21138 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21140 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21142 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21144 Fix more problems found by GCC 4.6.0's static checks.
21146 * xdisp.c (vmessage): Use a better test for character truncation.
21148 * charset.c (load_charset_map): <, not <=, for optimization,
21149 and to avoid potential problems with integer overflow.
21150 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21151 * casetab.c (set_identity, shuffle): Likewise.
21152 * editfns.c (Fformat): Likewise.
21153 * syntax.c (skip_chars): Likewise.
21155 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21156 This also lets GCC 4.6.0 generate slightly better loop code.
21158 * callint.c (Fcall_interactively): <, not <=, for optimization.
21159 (Fcall_interactively): Count the number of arguments produced,
21160 not the number of arguments given. This is simpler and lets GCC
21161 4.6.0 generate slightly better code.
21163 * ftfont.c: Distingish more carefully between FcChar8 and char.
21164 The previous code passed unsigned char * to a functions like
21165 strlen and xstrcasecmp that expect char *, which does not
21166 conform to the C standard.
21167 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21168 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21169 char * when the C standard requires it.
21171 * keyboard.c (read_char): Remove unused var.
21173 * eval.c: Port to Windows vsnprintf (Bug#8435).
21174 Include <limits.h>.
21175 (SIZE_MAX): Define if the headers do not.
21176 (verror): Do not give up if vsnprintf returns a negative count.
21177 Instead, grow the buffer. This ports to Windows vsnprintf, which
21178 does not conform to C99. Problem reported by Eli Zaretskii.
21179 Also, simplify the allocation scheme, by avoiding the need for
21180 calling realloc, and removing the ALLOCATED variable.
21182 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21184 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21185 But keep the doprint source code for now, as we might revamp it
21186 and use it again (Bug#8435).
21187 * lisp.h (doprnt): Remove.
21188 * Makefile.in (base_obj): Remove doprnt.o.
21189 * deps.mk (doprnt.o): Remove.
21191 error: Print 32- and 64-bit integers portably (Bug#8435).
21192 Without this change, on typical 64-bit hosts error ("...%d...", N)
21193 was used to print both 32- and 64-bit integers N, which relied on
21194 undefined behavior.
21195 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21196 * lisp.h (error, verror): Mark as printf-like functions.
21197 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21198 Report overflow in size calculations when allocating printf buffer.
21199 Do not truncate output string at its first null byte.
21200 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21201 Truncate the output at a character boundary, since vsnprintf does not
21203 * charset.c (check_iso_charset_parameter): Convert internal
21204 character to string before calling 'error', since %c now has the
21206 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21207 overflow when computing char to be passed to 'error'. Do not
21208 pass Lisp_Object to 'error'; pass the integer instead.
21209 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21210 formatted with plain %d.
21212 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21214 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21216 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21218 * xterm.c (x_catch_errors): Remove duplicate declaration.
21220 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21222 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21224 2011-04-10 Jim Meyering <meyering@redhat.com>
21226 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21227 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21228 return ssize_t not "int", and use size_t as the buffer length.
21229 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21230 * gnutls.h: Update declarations.
21231 * process.c (read_process_output): Use ssize_t, to match.
21232 (send_process): Likewise.
21234 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21236 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21238 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21240 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21241 Use unsigned char, to match FcChar8 type definition.
21243 * xterm.c (handle_one_xevent):
21244 * xmenu.c (create_and_show_popup_menu):
21245 * xselect.c (x_decline_selection_request)
21246 (x_reply_selection_request): Avoid type-punned deref of X events.
21248 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21250 Fix some uses of `int' instead of EMACS_INT.
21251 * search.c (string_match_1, fast_string_match)
21252 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21253 (scan_buffer, find_next_newline_no_quit)
21254 (find_before_next_newline, search_command, Freplace_match)
21255 (Fmatch_data): Make some `int' variables be EMACS_INT.
21257 * xdisp.c (display_count_lines): 3rd argument and return value now
21258 EMACS_INT. All callers changed.
21259 (pint2hrstr): Last argument is now EMACS_INT.
21261 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21262 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21263 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

21301 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21303 * keyboard.c (read_char): Call Lisp function help-form-show,
21304 instead of using internal_with_output_to_temp_buffer.
21305 (Qhelp_form_show): New var.
21306 (syms_of_keyboard): Use DEFSYM macro.
21308 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21321 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21323 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21325 Fix more problems found by GCC 4.6.0's static checks.
21327 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

21331 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21333 * xdisp.c (vmessage): Mark as a printf-like function.
21335 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

21339 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21340 printf-like functions.
21341 (tiff_load): Add casts to remove these marks before passing them
21342 to system-supplied API.
21344 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21346 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21347 This avoids several warnings with gcc -Wstrict-overflow.
21348 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21349 directly, rather than having caller test rule sign. This avoids
21350 some unnecessary tests.
21351 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21352 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21353 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21355 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21356 (xfont_open): Avoid unnecessary tests.
21358 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21360 * composite.h, composite.c (composition_gstring_put_cache):
21361 Use EMACS_INT, not int, for length.
21363 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21364 breaking out part of COMPOSITION_DECODE_RULE.
21365 (COMPOSITION_DECODE_RULE): Use it.
21366 * composite.c (get_composition_id): Remove unused local vars,
21367 by using the new macro.
21369 * textprop.c (set_text_properties_1): Change while to do-while,
21370 since the condition is always true at first.
21372 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21373 (interval_deletion_adjustment): Return unsigned value.
21376 * process.c (list_processes_1, create_pty, read_process_output):
21377 (exec_sentinel): Remove vars that were set but not used.
21378 (create_pty): Remove unnecessary "volatile"s.
21379 (Fnetwork_interface_info): Avoid possibility of int overflow.
21380 (read_process_output): Do adaptive read buffering even if carryover.
21381 (read_process_output): Simplify nbytes computation if buffered.

21385 * syntax.c (scan_words): Remove var that was set but not used.
21386 (update_syntax_table): Use unsigned instead of int.
21388 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21389 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.

21392 * print.c (print_error_message): Avoid int overflow.
21394 * font.c (font_list_entities): Redo for clarity,
21395 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21397 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21398 (font_score): Avoid potential overflow in diff calculation.
21400 * fns.c (substring_both): Remove var that is set but not used.
21401 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21403 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21405 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21406 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21407 can always succeed if overflow has undefined behavior.
21409 * search.c (boyer_moore, wordify): Remove vars set but not used.
21410 (wordify): Omit three unnecessary tests.
21412 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21413 All callers changed. This avoids the need for an unused var.
21415 * casefiddle.c (casify_region): Remove var that is set but not used.
21417 * dired.c (file_name_completion): Remove var that is set but not used.
21419 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21421 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21422 (Finsert_file_contents): Remove unnecessary code checking fd.
21424 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21425 Check for integer overflow on size calculations.
21427 * buffer.c (Fprevious_overlay_change): Remove var that is set
21430 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21431 Remove vars that are set but not used.
21432 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21433 (timer_check_2): Mark vars as initialized.
21435 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21437 * image.c (lookup_image): Remove var that is set but not used.
21438 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21440 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21441 that are set but not used.
21443 * xfns.c (make_invisible_cursor): Don't return garbage
21444 if XCreateBitmapFromData fails (Bug#8410).
21446 * xselect.c (x_get_local_selection, x_handle_property_notify):
21447 Remove vars that are set but not used.
21449 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21450 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21452 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21453 Remove var that is set but not used.
21454 (scroll_bar_windows_size): Now size_t, not int.
21455 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21456 Check for overflow.
21458 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21459 (map_tty_color) [!defined MSDOS]: Likewise.
21461 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21463 * coding.c: Remove vars that are set but not used.
21464 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21465 All callers changed.
21466 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21467 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21468 (decode_coding_charset): Remove vars that are set but not used.
21470 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21471 that is set but not used.
21473 * print.c (print_object): Remove var that is set but not used.
21475 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21476 The gnulib version avoids calling malloc in the usual case,
21477 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21478 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21479 * filelock.c (current_lock_owner): Likewise.
21480 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21481 * sysdep.c: Include allocator.h, careadlinkat.h.
21482 (emacs_no_realloc_allocator): New static constant.
21483 (emacs_readlink): New function.
21484 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21485 ../lib/careadlinkat.h.
21487 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21489 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21490 first non-nil return value).
21492 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21494 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21495 if not defined (Bug#8403).
21497 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21499 * xdisp.c (display_count_lines): Remove parameter `start',
21500 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21501 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21502 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21504 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21505 and thereabouts. All callers changed.
21506 (get_per_char_metric): Remove parameter `f', unused since
21507 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21509 2011-04-02 Jim Meyering <meyering@redhat.com>
21511 do not dereference NULL upon failed strdup
21512 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21513 (ns_get_family): Likewise.
21515 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21517 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21519 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21521 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21524 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21526 Add lexical binding.
21528 * window.c (Ftemp_output_buffer_show): New fun.
21529 (Fsave_window_excursion):
21530 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21532 * lread.c (lisp_file_lexically_bound_p): New function.
21533 (Fload): Bind Qlexical_binding.
21534 (readevalloop): Remove `evalfun' arg.
21535 Bind Qinternal_interpreter_environment.
21536 (Feval_buffer): Bind Qlexical_binding.
21537 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21539 (syms_of_lread): Declare `lexical-binding'.
21541 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21543 * keyboard.c (eval_dyn): New fun.
21544 (menu_item_eval_property): Use it.
21546 * image.c (parse_image_spec): Use Ffunctionp.
21548 * fns.c (concat, mapcar1): Accept byte-code-functions.
21550 * eval.c (Fsetq): Handle lexical vars.
21551 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21552 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21553 (FletX, Flet): Obey lexical binding.
21554 (Fcommandp): Handle closures.
21555 (Feval): New `lexical' arg.
21556 (eval_sub): New function extracted from Feval. Use it almost
21557 everywhere where Feval was used. Look up vars in lexical env.
21559 (Ffunctionp): Move from subr.el.
21560 (Ffuncall): Handle closures.
21561 (apply_lambda): Remove `eval_flags'.
21562 (funcall_lambda): Handle closures and new byte-code-functions.
21563 (Fspecial_variable_p): New function.
21564 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21565 but without exporting it to Lisp.
21567 * doc.c (Fdocumentation, store_function_docstring):
21568 * data.c (Finteractive_form): Handle closures.
21570 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21573 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21575 (exec_byte_code): New function extracted from Fbyte_code to handle new
21576 calling convention for byte-code-functions. Add new byte-codes.
21578 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21580 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21582 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21584 * xdisp.c (redisplay_internal): Fix prototype.
21586 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21588 * xdisp.c (SCROLL_LIMIT): New macro.
21589 (try_scrolling): Use it when setting scroll_limit.
21590 Limit scrolling to 100 screen lines.
21591 (redisplay_window): Even when falling back on "recentering",
21592 position point in the window according to scroll-conservatively,
21593 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21595 (try_scrolling): When point is above the window, allow searching
21596 as far as scroll_max, or one screenful, to compute vertical
21597 distance from PT to the scroll margin position. This prevents
21598 try_scrolling from unnecessarily failing when
21599 scroll-conservatively is set to a value slightly larger than the
21600 window height. Clean up the case of PT below the margin at bottom
21601 of window: scroll_max can no longer be INT_MAX. When aggressive
21602 scrolling is in use, don't let point enter the opposite scroll
21603 margin as result of the scroll.
21604 (syms_of_xdisp) <scroll-conservatively>: Document the
21605 threshold of 100 lines for never-recentering scrolling.
21607 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21609 * dispextern.h (move_it_by_lines):
21610 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21611 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21612 (message_log_check_duplicate): Remove parameters `prev_bol' and
21613 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21614 (redisplay_internal): Remove parameter `preserve_echo_area',
21615 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21617 * indent.c (Fvertical_motion):
21618 * window.c (window_scroll_pixel_based, Frecenter):
21619 Don't pass `need_y_p' to `move_it_by_lines'.
21621 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21623 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21624 steal a few bits to be more compact.
21625 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21626 Remove unneeded casts.
21628 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21630 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21632 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21633 binding" message (bug#7967).
21635 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21637 Fix more problems found by GCC 4.6.0's static checks.
21639 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21640 Remove unused local var.
21642 * editfns.c (Fmessage_box): Remove unused local var.
21644 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21645 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21646 Omit unused local vars.
21647 * window.c (shrink_windows): Omit unused local var.
21648 * menu.c (digest_single_submenu): Omit unused local var.
21649 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21650 Omit unused local var.
21652 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21653 Don't assume string length fits in int.
21654 (keyremap_step, read_key_sequence): Use size_t for sizes.
21655 (read_key_sequence): Don't check last_real_key_start redundantly.
21657 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21658 instead of alloca (Bug#8344).
21660 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21661 (Fbacktrace_frame): Don't assume nframes fits in int.
21663 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21665 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21668 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21670 * cm.c (calccost): Turn while-do into do-while, for clarity.
21672 * keyboard.c (syms_of_keyboard): Use the same style as later
21673 in this function when indexing through an array. This also
21674 works around GCC bug 48267.
21676 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21678 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21680 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21681 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21683 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21684 This avoids undefined behavior on integer overflow, and is a bit
21685 more convenient anyway since it is compared to a size_t variable.
21687 Variadic C functions now count arguments with size_t, not int.
21688 This avoids an unnecessary limitation on 64-bit machines, which
21689 caused (substring ...) to crash on large vectors (Bug#8344).
21690 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21691 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21692 All variadic functions and their callers changed accordingly.

21699 * fns.c (concat): Likewise.
21700 * frame.c (x_set_frame_parameters): Likewise.
21701 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21702 0 if not found, not -1. All callers changed.
21704 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21705 (stack_copy_size): Now size_t, not int.
21706 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21708 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21710 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21711 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21712 All callers changed.
21714 * lisp.h (multibyte_char_to_unibyte):
21715 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21716 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21720 * keymap.c (push_key_description):

21910 * callint.c (Fcall_interactively):
21911 * buffer.c (Fkill_all_local_variables):
21912 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21914 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21915 unconditionally since it does the check itself.
21917 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21919 Fix more problems found by GCC 4.5.2's static checks.
21921 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21922 the first time through the loop, since we know p0 < p1 then.
21923 This also avoids a gcc -Wstrict-overflow warning.
21925 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21926 leading to a memory leak, possible in functions like
21927 load_charset_map_from_file that can allocate an unbounded number
21928 of objects (Bug#8318).
21930 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21931 that could (at least in theory) be that large.
21933 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21934 This is less likely to overflow, and avoids undefined behavior if
21935 overflow does occur. All callers changed. Use strtoul to scan
21936 for the unsigned long integer.
21937 (pint2hrstr): Simplify and tune code slightly.

21953 * process.c (Fmake_network_process): Use socklen_t, not int,
21954 where POSIX says socklen_t is required in portable programs.
21955 This fixes a porting bug on hosts like 64-bit HP-UX, where
21956 socklen_t is wider than int (Bug#8277).
21957 (Fmake_network_process, server_accept_connection):
21958 (wait_reading_process_output, read_process_output):
21961 * process.c: Rename or move locals to avoid shadowing.

21971 Make tparam.h and terminfo.c consistent.
21972 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21973 Include tparam.h instead, since it declares them.
21974 * cm.h (PC): Remove extern decl; tparam.h now does this.
21975 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21976 * terminfo.c: Include tparam.h, to check interfaces.
21977 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21978 (tparam): Adjust signature to match interface in tparam.h;
21979 this removes some undefined behavior. Check that outstring and len
21980 are zero, which they always are with Emacs.
21981 * tparam.h (PC, BC, UP): New extern decls.
21983 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21984 (xftfont_open): Rename locals to avoid shadowing.

22002 (composition_update_it): Mark var as initialized.
22003 (find_automatic_composition): Mark vars as initialized,
22004 with a FIXME (Bug#8290).

22010 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22011 to avoid shadowing.

22023 Fix pointer signedness.
22024 (alsa_choose_format): Remove unused local var.
22025 (wav_play): Initialize a variable to 0, to prevent undefined
22026 behavior (Bug#8278).
22028 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22030 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22032 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22033 clobbering (Bug#8298).
22034 * sysdep.c (sys_subshell): Likewise.
22035 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22037 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22038 This should get cleaned up, so that child_setup has the
22039 same signature on all platforms.
22041 * callproc.c (call_process_cleanup): Now static.
22042 (relocate_fd): Rename locals to avoid shadowing.
22044 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22046 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22047 not to be necessary, and produces flickering.
22049 2011-03-20 Glenn Morris <rgm@gnu.org>
22051 * config.in: Remove file.
22053 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22100 * unexelf.c (unexec): Name an expression,
22101 to avoid gcc -Wbad-function-cast warning.

22103 n rather than nn, a way that does not involve shadowing.
22104 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22106 * deps.mk (unexalpha.o): Remove; unused.

22171 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22172 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22173 some of which prompt warnings from gcc -Wbad-function-cast.
22174 (Fformat_time_string, Fencode_time, Finsert_char):
22175 (Ftranslate_region_internal, Fformat):
22176 Rename or remove local vars to avoid shadowing.

22201 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22202 (GC_STRING_CHARS): Remove; not used.
22203 (Fmemory_limit): Cast sbrk's returned value to char *.
22205 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22206 avoids undefined behavior in theory.
22208 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22210 Use functions, not macros, for up- and down-casing (Bug#8254).
22211 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22212 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22213 to use the following functions instead of these macros.
22214 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22215 EMACS_INT, since callers assume the returned value fits in int.
22216 (upcase1): Likewise, for UPCASE_TABLE.
22217 (uppercasep, lowercasep, upcase): New static inline functions.
22218 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22227 which gcc can warn about.
22228 (regex_compile, re_match_2_internal): Mark locals as initialized.
22229 (RETALLOC_IF): Define only if needed.
22230 (WORDCHAR_P): Likewise. This one is never needed, but is used
22231 only in a comment talking about a compiler bug, so put inside
22232 the #if 0 of that comment.
22233 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22234 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22237 * search.c (boyer_moore): Rename locals to avoid shadowing.

22260 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22261 New macros, so that the caller can use some names other than
22262 gcpro1, gcpro2, etc.
22263 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22265 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22266 argument, for consistency with GCPRO2_VAR, etc: it is now the
22267 prefix of the variable, not the variable itself. All uses
22269 * dired.c (directory_files_internal, file_name_completion):
22270 Rename locals to avoid shadowing.
22272 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22273 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22274 dired.c's scmp function, had undefined behavior.
22275 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22276 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22277 * buffer.h: ... to here, because these macros use current_buffer,
22278 and the new implementation with inline functions needs to have
22279 current_buffer in scope now, rather than later when the macros
22281 (downcase, upcase1): New static inline functions.
22282 (DOWNCASE, UPCASE1): Reimplement using these functions.
22283 This avoids undefined behavior in expressions like
22284 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22285 from race conditions in accessing the global variables
22286 case_temp1 and case_temp2.
22287 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22288 * lisp.h (case_temp1, case_temp2): Remove their decls.
22289 * character.h (ASCII_CHAR_P): Move from here ...
22290 * lisp.h: ... to here, so that the inline functions mentioned
22291 above can use them.
22293 * dired.c (directory_files_internal_unwind): Now static.
22295 * fileio.c (file_name_as_directory, directory_file_name):
22296 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22298 (file_name_as_directory): Use const pointers when appropriate.
22299 (Fexpand_file_name): Likewise. In particular, newdir might
22300 point at constant storage, so make it a const pointer.
22301 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22302 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22304 (Fset_file_times, Finsert_file_contents, auto_save_error):

22309 to avoid shadowing.
22311 * marker.c (bytepos_to_charpos): Remove; unused.
22313 * lisp.h (verify_bytepos, count_markers): New decls,
22314 so that gcc does not warn that these functions aren't declared.
22316 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22317 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22318 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22319 (copy_text): Remove unused local var.
22321 * filelock.c (within_one_second): Now static.
22322 (lock_file_1): Rename local to avoid shadowing.
22324 * buffer.c (fix_overlays_before): Mark locals as initialized.
22325 (fix_start_end_in_overlays): Likewise. This function should be
22326 simplified by using pointers-to-pointers, but that's a different
22328 (switch_to_buffer_1): Now static.
22329 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22330 (report_overlay_modification): Rename locals to avoid shadowing.
22332 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22333 Fix pointer signedness issue.
22334 (sys_subshell): Mark local as volatile if checking for lint,
22335 to suppress a gcc -Wclobbered warning that does not seem to be right.
22336 (MAXPATHLEN): Define only if needed.
22338 * process.c (serial_open, serial_configure): Move decls from here ...
22339 * systty.h: ... to here, so that they can be checked.
22341 * fns.c (get_random, seed_random): Move extern decls from here ...
22342 * lisp.h: ... to here, so that they can be checked.
22344 * sysdep.c (reset_io): Now static.
22345 (wait_for_termination_signal): Remove; unused.
22347 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22348 (copy_keymap_item, append_key, push_text_char_description):
22350 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22351 (DENSE_TABLE_SIZE): Remove; unused.
22352 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22353 (describe_map_tree):
22354 Rename locals to avoid shadowing.
22356 * keyboard.c: Declare functions static if they are not used elsewhere.

22505 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
