3 * sheap.c (report_sheap_usage): Use message, not message1, so
4 that we don't try to create a buffer while we're in the middle
5 of dumping Emacs. Explain why.
7 2013-02-19 Eli Zaretskii <eliz@gnu.org>
9 * w32proc.c (new_child): Avoid leaking handles if the subprocess
10 resources were not orderly released.
12 2013-02-17 Eli Zaretskii <eliz@gnu.org>
14 * xdisp.c (x_draw_vertical_border): For a window that is neither
15 the leftmost nor the rightmost, redraw both the left and the right
16 vertical borders. (Bug#13723)

31 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
33 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
34 * frame.c (syms_of_frame): ... to here.
36 2013-02-16 Eli Zaretskii <eliz@gnu.org>
38 * w32.c (sys_chown): Remove unused function.
40 * w32term.c <input_signal_count>: Declare 'volatile'
41 unconditionally. (Bug#9066)
43 * w32.c (set_errno): Reset h_errno and don't set it to any other
44 value. Set errno instead.
45 (check_errno): Reset h_errno.
46 (sys_socket, socket_to_fd, sys_bind, sys_connect)

53 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
55 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
57 2013-02-15 Eli Zaretskii <eliz@gnu.org>
59 * keyboard.c (read_char): Fix calculation of auto-save time out
60 when auto-save-timeout is less than 4. (Bug#13720)

70 (socket_to_fd): Add assertion against indexing fd_info[] with a
71 value that is out of bounds.
72 (sys_accept): If fd is negative, do not set up the child_process
73 structure for reading.
75 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
77 * composite.c (fill_gstring_header): Remove useless prototype.

89 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
91 Fix AIX port (Bug#13650).
92 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
93 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
94 was #undeffed earlier, so it cannot be used as a macro here.
95 Use the constant and not the macro.
97 2013-02-15 Eli Zaretskii <eliz@gnu.org>
99 * w32proc.c (new_child): If no vacant slots are found in
100 child_procs[], make another pass looking for slots whose process
101 has exited or died. (Bug#13546)
103 * w32.c (sys_pipe): When failing due to file descriptors above
104 MAXDESC, set errno to EMFILE.
105 (_sys_read_ahead): Update cp->status when failing to read serial
106 communications input, so that the status doesn't stay at
107 STATUS_READ_IN_PROGRESS. (Bug#13546)
109 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
111 * gtkutil.c (tb_size_cb): New function.

119 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
121 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
123 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
125 * font.c (font_range): Add pos_byte argument. Adjust comment
127 * font.h (font_range): Adjust prototype.
128 * composite.c (autocmp_chars): Pass byte position to font_range.

131 2013-02-13 Glenn Morris <rgm@gnu.org>
133 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
135 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
137 Improve AIX port some more (Bug#13650).
138 With this, it should be as good as it was in 23.3, though it's
139 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
140 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
141 * unexaix.c (start_of_text): Remove.
142 (_data, _text): Declare as char[], not int, as AIX manual suggests.
143 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
144 (orig_load_scnptr, orig_data_scnptr):
145 Now off_t, not long, since they are file offsets.
146 (make_hdr): Use _data, not start_of_data ().
147 This is the key part of the fix.
148 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
149 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
151 * pre-crt0.c (data_start): Initialize to 1.
152 This ports to compilers that optimize the external declaration
153 'int x = 0;' as if it were 'int x;' to shrink the executable.
155 Improve AIX port (Bug#13650).
156 This doesn't fix the bug, but it makes progress: Emacs builds now.
157 * unexaix.c: Include inttypes.h, stdarg.h.
158 (report_error, report_error_1): Mark as _Noreturn.
159 (report_error): Don't report the wrong errno.
160 (report_error_1): Now varargs. All callers changed.
161 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
162 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
163 (write_ptr): Use %p to print address rather than %lx and a cast
164 to unsigned long. Grow buffer a bit, to be safer.
166 2013-02-13 Eli Zaretskii <eliz@gnu.org>
168 * bidi.c (bidi_resolve_neutral): After finding the next
169 non-neutral character, accept NEUTRAL_ON type as well, because
170 directional control characters, such as LRE and RLE, have their
171 type converted to that by bidi_resolve_weak. This avoids aborts
172 when LRE/RLE follows a run of neutrals.
173 (bidi_move_to_visually_next): Assert that return value of
174 bidi_peek_at_next_level is non-negative. Negative values will
177 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
179 Minor getenv-related fixes.
180 * callproc.c (Fcall_process_region) [!DOS_NT]:
181 Avoid unnecessary duplicate call to getenv.
182 * callproc.c (init_callproc):
183 * dispnew.c (init_display):
184 * sysdep.c (sys_subshell):
185 Omit unnecessary cast of getenv or egetenv.
187 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
189 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
192 2013-02-12 Eli Zaretskii <eliz@gnu.org>
194 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
196 (display_line): Set w->region_showing to the value of
197 it->region_beg_charpos, not to -1. This fixes redisplay
198 optimization when cursor is moved up after M->. (Bug#13623)
200 (try_scrolling): Scroll text up more if point is too close to ZV
201 and inside the scroll margin. This makes sure point is moved
202 outside the scroll margin in these cases.
204 * window.h (struct window): region_showing can no longer be
207 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
209 Tune by using memchr and memrchr.
210 * doc.c (Fsnarf_documentation):
211 * fileio.c (Fsubstitute_in_file_name):
212 * search.c (find_newline, scan_newline):
213 * xdisp.c (pos_visible_p, display_count_lines):
214 Use memchr and memrchr rather than scanning byte-by-byte.
215 * search.c (find_newline): Rename from scan_buffer.
216 Omit first arg TARGET, as it's always '\n'. All callers changed.
218 Clean up read_key_sequence a tiny bit more.
219 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
220 (read_key_sequence): Remove unused locals.
222 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
224 Clean up read_key_sequence a bit; reread active keymaps after first event.
225 * keyboard.c (read_char, read_char_x_menu_prompt)
226 (read_char_minibuf_menu_prompt):
227 Replace nmaps+maps with a single `map' arg.
228 (follow_key): Operate on a single map.
229 (active_maps): New function.
230 (test_undefined): Also return true for nil bindings.
231 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
232 a single (composed) keymap. Remember `first_event' to choose the right
233 set of active keymaps. Recompute the set of keymaps after receiving
234 the first event. Remove GOBBLE_FIRST_EVENT.
235 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
236 * keyboard.h (read_char): Update declaration.
237 * lread.c (read_filtered_event): Adjust call to read_char.
239 2013-02-11 Eli Zaretskii <eliz@gnu.org>
241 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
242 Don't use the limitation on backwards movement when lines are truncated
243 in the window. (Bug#13675)
245 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
247 * marker.c (set_marker_internal): If desired position is passed
248 as a marker, avoid call to buf_charpos_to_bytepos.
249 * window.c (Fset_window_point): Omit redundant type checking.
250 (Fset_window_start): Likewise. Format comment.
251 (window_scroll_pixel_based): Use set_marker_restricted_both
252 with character and byte positions obtained from an iterator.
253 (Fset_window_configuration): Use set_marker_restricted_both.
254 * xdisp.c (message_dolog): Likewise.
256 2013-02-10 Eli Zaretskii <eliz@gnu.org>
258 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
259 When text lines are longer than window's screen lines, don't move back
260 too far. This speeds up some redisplay operations. (Bug#13675)
262 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
264 * syntax.c (scan_sexps_forward): Fix byte position calculation
265 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
267 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
269 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
272 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
274 Minor hashing refactoring.
275 * fns.c (SXHASH_REDUCE): Move to lisp.h.
276 (sxhash_float): Return EMACS_UINT, for consistency with the other
278 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
279 non-static inline function and therefore can't use static vars.
280 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
281 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
282 with the other hash functions.
284 2013-02-09 Eli Zaretskii <eliz@gnu.org>
286 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
287 XXXXXX part of the temporary file pattern is not downcased even
288 when w32-downcase-file-names is non-nil. (Bug#13661)
290 * xdisp.c (decode_mode_spec): Remove handling of %t.
292 * msdos.c (careadlinkatcwd): Remove.
294 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
296 * lread.c (skip_dyn_bytes): New function (bug#12598).
297 (read1): Use it. Use getc instead of READCHAR to read bytes.
298 (load_each_byte): Remove. Update users.
300 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
302 * search.c (scan_buffer): Calculate end byte position just once.
303 (scan_newline): Do not recalculate start_byte.
304 (search_command): Use eassert.
305 * syntax.c (struct lisp_parse_state): New member location_byte.
306 (scan_sexps_forward): Record from_byte and avoid redundant
307 character to byte position calculation ...
308 (Fparse_partial_sexp): ... here. Break too long line.
310 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
312 * lisp.h (make_uninit_vector): New function.
313 * alloc.c (Fvector, Fmake_byte_code):

325 * window.c (Fcurrent_window_configuration):
326 * xfaces.c (Fx_family_fonts):
327 * xselect.c (selection_data_to_lisp_data): Use it.
329 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
331 * coding.c (Fdefine_coding_system_internal): Use AREF where
332 argument is known to be a vector.
333 * fns.c (Flocale_info): Likewise for ASET.
334 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
335 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
337 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
339 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
342 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
343 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
344 updateCollectionBehaviour.
346 * nsterm.m (NEW_STYLE_FS): Remove.
347 (ns_last_use_native_fullscreen): New variable.
348 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
349 (x_set_window_size): Do not take title bar and tool bar into account
350 if isFullscreen returns YES.
351 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
352 (check_native_fs): New function.
353 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
354 (ns_term_init): Remove NEW_STYLE_FS.
355 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
356 and tool bar if isFullscreen returns NO.
357 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
358 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
360 (window:willUseFullScreenPresentationOptions:): New method.
361 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
362 Hide toolbar if not enabled (Bug#13444).
363 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
364 Restore tool bar if enabled, hide it otherwise (Bug#13444).
365 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
366 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
367 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
368 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
369 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
370 (syms_of_nsterm): Add ns-use-native-fullscreen.
372 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
374 * fileio.c (Qchoose_write_coding_system): Now static.
376 2013-02-04 Eli Zaretskii <eliz@gnu.org>
378 * xdisp.c (window_buffer_changed): region_showing can be negative,
379 which still means region is being displayed.
380 (redisplay_internal): Resurrect code that forced redisplay of the
381 whole window when showing region and the mark has changed.
382 Record the new mark position to allow redisplay optimizations.
383 (display_line): If it->region_beg_charpos is non-zero, set the
384 window's region_showing member to -1. (Bug#13623) (Bug#13626)
386 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
387 not bitfield of 1 bit.
389 2013-02-03 Daniel Colascione <dancol@dancol.org>
391 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
392 daemon mode works on cygw32 when Emacs is installed and not just
395 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
397 Avoid file time stamp bug on MS-Windows (Bug#13149).
398 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
399 as FAT32 doesn't update time stamps when truncating them.
400 Also, check that a file time stamp is not a multiple of 100 ns;
401 this should catch all instances of the problem on MS-Windows,
402 as its native file system resolution is 100 ns or worse, and
403 checking for a non-multiple of 100 ns should impose only a small
404 overhead on systems with ns resolution.
406 2013-02-02 Eli Zaretskii <eliz@gnu.org>
408 Avoid encoding file names on MS-Windows when they need to be run
409 through dostounix_filename.
410 * w32.c (normalize_filename): Accept an additional argument
411 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
412 downcase it even if w32-downcase-file-names is non-nil.
413 (dostounix_filename): Accept an additional argument MULTIBYTE and
414 pass it to normalize_filename.
415 (emacs_root_dir): Adjust.
417 * msdos.h (dostounix_filename): Adjust prototype.
419 * w32.h (dostounix_filename): Adjust prototype.
421 * msdos.c (dostounix_filename): Accept an additional argument and
423 (init_environment): Adjust callers of dostounix_filename.
425 * fileio.c (Ffile_name_directory, file_name_as_directory)
426 (directory_file_name, Fexpand_file_name)
427 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
429 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
431 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
432 variables, as egetenv is case-insensitive for DOS_NT.
434 * dired.c (file_name_completion): Don't call Fdirectory_file_name
435 with an encoded file name.
437 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
438 Adjust calls to dostounix_filename.
440 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
442 * unexw32.c (unexec): Adjust call to dostounix_filename.
444 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
446 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
449 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
452 * callproc.c (Fcall_process): Make sure program name in PATH and
453 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
454 is passed to exec/spawnve, which fails unless the file-name
457 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
458 even if w32-quote-process-args is nil.
460 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
462 Fix timestamp bug when write-region appends nothing (Bug#13149).
463 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
464 the file's time stamp doesn't change if Emacs happens to write nothing
465 to the file, and on a buggy file system this could cause Emacs to
466 incorrectly infer that the file system doesn't have the bug.
467 Avoid this problem by inhibiting the inference in this case.
469 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
471 * window.h (struct window): Convert base_line_number, base_line_pos
472 and column_number_displayed members from Lisp_Object to ptrdiff_t.
473 Convert region_showing member from Lisp_Object to bitfield.
474 Remove sequence_number member. Adjust comments.
475 * window.c (sequence_number): Remove.
476 (make_window): Initialize column_number_displayed.
477 * print.c (print_object): Follow the printed representation of
478 frames and print window pointer to distinguish between windows.
479 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
480 * xdisp.c (wset_base_line_number, wset_base_line_pos)
481 (wset_column_number_displayed, wset_region_showing): Remove.
482 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
483 (try_scrolling, try_cursor_movement, redisplay_window)
484 (try_window_reusing_current_matrix, try_window_id, display_line)
485 (display_mode_lines, decode_mode_spec): Adjust users.
486 * .gdbinit (pwinx): Do not print sequence_number.
488 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>

491 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
492 * dired.c: Include <fcntl.h>.
493 (open_directory): New function, which uses open and fdopendir
494 rather than opendir. DOS_NT platforms still use opendir, though.
495 (directory_files_internal, file_name_completion): Use it.
496 (file_attributes): New function, with most of the old Ffile_attributes.
497 (directory_files_internal, Ffile_attributes): Use it.
498 (file_attributes, file_name_completion_stat): First arg is now fd,
499 not dir name. All uses changed. Use fstatat rather than lstat +
501 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
502 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
503 (emacs_readlinkat): New function, with much of the old
504 Ffile_symlink_p, but with an fd argument for speed.
505 It uses readlinkat rather than careadlinkatcwd, so that it
506 need not assume the working directory.
507 (Ffile_symlink_p): Use it.
508 * filelock.c (current_lock_owner): Use emacs_readlinkat
509 rather than emacs_readlink.
510 * lisp.h (emacs_readlinkat): New decl.
511 (READLINK_BUFSIZE, emacs_readlink): Remove.
512 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
513 (emacs_norealloc_allocator, emacs_readlink): Remove.
514 This stuff is moved to fileio.c.
515 * w32.c (fstatat, readlinkat): New functions.
516 (careadlinkat): Don't check that fd == AT_FDCWD.
517 (careadlinkatcwd): Remove; no longer needed.

522 (Fwrite_region): Update for new choose_write_coding_system args.
523 Move the last piece of choose_write_coding_system here. (Bug#13522)
524 (syms_of_fileio): Add choose-write-coding-system.
526 2013-01-30 Eli Zaretskii <eliz@gnu.org>
528 * w32.c (sys_open): Zero out the flags for the new file descriptor.
529 (sys_close): Zero out the flags for the file descriptor before
530 closing it. (Bug#13546)
532 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
533 (logon_network_drive, stat_worker, symlink, chase_symlinks):
534 Use CharNextExA and CharPrevExA to iterate over file names encoded in
537 * w32.c (w32_get_long_filename, init_environment, readlink):
538 Support file names encoded in DBCS codepages.
539 (readlink): Use the current file-name-coding-system, not the ANSI
540 codepage, to decode and handle targets of symlinks.
542 2013-01-28 Eli Zaretskii <eliz@gnu.org>
544 * w32.c (opendir): Now accepts a 'const char *'.
546 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
548 Remove obsolete redisplay code. See the discussion at
549 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
550 * dispnew.c (preemption_period, preemption_next_check): Remove.
551 (Vredisplay_preemption_period): Likewise.
552 (update_frame, update_single_window, update_window, update_frame_1):
553 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
554 used, following the 2012-06-22 change.
556 2013-01-25 Eli Zaretskii <eliz@gnu.org>
558 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
560 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
562 * font.c (num_fonts): Remove the leftover from old
563 debugging code. Adjust comment style here and there.
564 * insdel.c (insert_1): Remove.
565 * lisp.h (insert_1): Remove prototype.

568 2013-01-25 Eli Zaretskii <eliz@gnu.org>
570 * w32.c (max_filename_mbslen): New function.
571 (normalize_filename, readdir): Use it to detect locales where ANSI
572 encoding of file names uses a double-byte character set (DBCS).
573 If a DBCS encoding is used, advance by characters using
574 CharNextExA, instead of incrementing a 'char *' pointer.
575 Use _mbslwr instead of _strlwr. (Bug#13515)
577 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
578 request of memory reservation to 1.7GB. (Bug#13065)
580 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
582 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
583 at check_extra_latin label. (Bug#13505)
585 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
587 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
588 Avoid redundant calls to strlen.
590 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
592 Drop async_visible and async_iconified fields of struct frame.
593 This is possible because async input is gone; for details, see
594 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
595 * frame.h (struct frame): Remove async_visible and async_iconified
596 members, convert garbaged to unsigned bitfield. Adjust comments.
597 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
598 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
599 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
600 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
601 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
603 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
604 properly. Likewise for obscured.
606 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
609 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
611 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
613 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
614 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
616 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
618 * xdisp.c (message2, message2_nolog): Remove functions.
619 (message3, message3_nolog): Extract nbytes and multibyteness directly
620 from the string. Change all callers.
621 (message3_nolog): Don't set message_enable_multibyte since set_message
622 will reset it anyway.
623 (message1, message1_nolog): Use message3.
624 (vmessage): Use a stack allocated buffer rather than f->message_buf.
625 (with_echo_area_buffer): Remove last two arguments. Update all callers.
626 (set_message): Drop all but the second arg, which has to be a string.
627 (set_message_1): Simplify now that we know that a1 is NULL and the
628 second arg is a string.
629 * frame.h (struct frame): Remove `message_buf' field.
630 Use glyphs_initialized_p instead.
631 (FRAME_MESSAGE_BUF): Remove macro.

633 * lisp.h (message2, message2_nolog): Remove declarations.
634 (message3, message3_nolog): Update declarations.
635 * keyboard.c (read_char_minibuf_menu_text)
636 (read_char_minibuf_menu_width): Remove vars.
637 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
638 to correctly handle multibyte strings.
639 * frame.c (delete_frame): Don't free message_buf any more.
640 * editfns.c (message_text, message_length): Remove vars.
641 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
642 * fileio.c (auto_save_error): Use message3 instead of message2.
643 * dispnew.c (adjust_frame_message_buffer): Remove function.
645 2013-01-23 Eli Zaretskii <eliz@gnu.org>
647 * w32term.c (w32fullscreen_hook): Account correctly for the screen
648 real estate used for the tool bar and the menu bar.
650 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
652 * insdel.c (prepare_to_modify_buffer): Force redisplay if
653 hidden buffer is prepared to modification (Bug#13164).
655 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
657 * window.h (struct window): Change window_end_valid member from
658 Lisp_Object to a bitfield. Adjust comments.
659 (wset_window_end_valid): Remove.
660 * window.c (adjust_window_count): Clear window_end_valid.
661 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
662 (Fwindow_line_height, set_window_buffer, Frecenter)
663 (Fsplit_window_internal, Fdelete_other_windows_internal)
664 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
665 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
666 * xdisp.c (check_window_end, reconsider_clip_changes)
667 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
668 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
669 (find_first_unchanged_at_end_row, try_window_id): Likewise.
671 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
673 * xdisp.c (mark_window_display_accurate): Simplify the loop
674 assuming that the only one of vchild, hchild or buffer window
675 slots is non-nil. Call mark_window_display_accurate_1 for
676 the leaf windows only.
677 (mark_window_display_accurate_1): Always assume leaf window.
680 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
682 * emacs.c (Qkill_emacs_hook): Now static.
684 * fileio.c (Finsert_file_contents): Simplify.
685 Remove unnecessary assignments and tests.
687 2013-01-21 Eli Zaretskii <eliz@gnu.org>
689 * w32.c (acl_set_file): Don't test for errors unless
690 set_file_security returns FALSE. Avoids spurious errors when
693 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
695 * fileio.c (Finsert_file_contents): Revert code introduced at
696 2013-01-18 in favor of the simpler and generally better fix.
697 Save stack space by removing 'buffer' and reusing 'read_buf'
700 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
702 * lisp.h (eabs): Define unconditionally (Bug#13419).
703 The old "#if !defined (eabs)" was an unnecessary revenant of back
704 when this macro was called "abs". Document 'eabs' better.
706 2013-01-19 Glenn Morris <rgm@gnu.org>
708 * fns.c (Frandom): Doc fix.
710 2013-01-19 Eli Zaretskii <eliz@gnu.org>
712 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
713 segfault when there are lots of overlays.
715 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
716 when there are lots of overlays.
717 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
718 for the details and a way to reproduce.
720 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
722 * fileio.c: Use O_APPEND to append.
723 This corresponds better to the natural interpretation of "append",
724 and avoids the need to open the output file twice, or to invoke
725 lseek when APPEND is neither nil nor a number.
726 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
727 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
728 file possibly twice, and lseeking to its end; this avoids the
729 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
730 at the same time: the combination is never needed and apparently
731 it doesn't work with DOS_NT.
733 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
734 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
736 Allow floating-point file offsets.
737 Problem reported by Vitalie Spinu in
738 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
739 * fileio.c (emacs_lseek): Remove.
740 (file_offset): New function.
741 (Finsert_file_contents, Fwrite_region): Use it.
743 2013-01-19 Chong Yidong <cyd@gnu.org>
745 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
746 aborting on Fsignal (Bug#13289).
748 2013-01-19 Eli Zaretskii <eliz@gnu.org>
750 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
751 set_file_security as failure due to insufficient privileges.
752 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
753 (fstat): Return owner and group like 'stat' and 'lstat' do.
755 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
757 Work around bug in CIFS and vboxsf file systems (Bug#13149).
758 The bug was observed on Ubuntu operating inside a virtual machine,
759 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
760 The workaround introduces a race condition on non-buggy hosts,
761 but it's an unlikely race and anyway there's a nearly identical
762 nearby race that can't be fixed.
763 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
765 (Fwrite_region): Test for file system time stamp bug.
766 (init_fileio): New function.
767 * lisp.h (init_fileio): Declare it.
768 * emacs.c (main): Call it.
770 * fileio.c (Finsert_file_contents): Simplify new diagnostic
771 and make it more consistent with other stat-failure diagnostics.
773 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
775 Fix crash when inserting data from non-regular files.
776 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
777 for the error description produced by valgrind.
778 * fileio.c (read_non_regular): Rename to read_contents.
779 Free Lisp_Save_Value object used to pass parameters.
780 (read_non_regular_quit): Rename to read_contents_quit.
781 (Finsert_file_contents): Redesign internal file reading loop to adjust
782 gap and end positions after each read and so help make_gap to work
783 properly. Do not signal an I/O error too early and so do not leave
784 not yet decoded characters in a buffer, which was the reason of
785 redisplay crash. Use list2 to build return value. Adjust comments.
787 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
789 Close a race when statting and reading files (Bug#13149).
790 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
791 This avoids a race if the file is renamed between stat and open.
792 This race is not the problem originally noted in Bug#13149;
793 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
795 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

803 * alloc.c (format_save_value): Rename to make_save_value.
804 (make_save_pointer): New function.
805 (record_xmalloc): Use make_save_pointer.
806 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
807 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
808 Change users of make_save_value to make_save_pointer.
809 Likewise for format_save_value and make_save_value.

826 * fileio.c (non_regular_fd, non_regular_inserted)
827 (non_regular_nbytes): Remove.
828 (Finsert_file_contents): Convert trytry to ptrdiff_t.
829 Use format_save_value to pass parameters to read_non_regular.
830 (read_non_regular): Use XSAVE_ macros to extract parameters.
832 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
834 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
836 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
838 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
839 extraction from any Lisp_Save_Value slot. Add type checking.
840 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
841 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
842 * xselect.c: All users changed.
844 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

861 * dired.c (directory_files_internal_unwind):
862 * fileio.c (do_auto_save_unwind):
863 * gtkutil.c (pop_down_dialog):
864 * keymap.c (map_keymap_char_table_item):
865 * lread.c (load_unwind):
866 * nsmenu.m (pop_down_menu):
867 * print.c (print_object) [GC_MARK_STACK]:
868 * xfns.c (clean_up_file_dialog):
869 * xmenu.c (cleanup_widget_value_tree):
870 Omit casts between XSAVE_POINTER and a pointer type.
872 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
874 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
875 * eval.c (eval_sub): Protect `form' from being GCed before its
876 car and cdr becomes protected with the backtrace entry.

888 (free_misc): Likewise. Adjust comment.
889 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
890 (free_save_value): Likewise.
891 (mark_object): Likewise.
892 * editfns.c (save_excursion_save): Pack everything within
893 Lisp_Save_Value and so avoid xmalloc.
894 (save_excursion_restore): Adjust to match new layout. Use free_misc
895 because we do not allocate extra memory any more. Add eassert.
896 * print.c (print_object): New code to print Lisp_Save_Value. Do not
897 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
898 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
899 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
900 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.

954 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
956 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):

963 string cross-reference(s).
965 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
967 Avoid unnecessary byte position calculation for the gap movement.
968 Since all users of move_gap do CHAR_TO_BYTE for other purposes
969 anyway, all of them should use move_gap_both instead.
970 * lisp.h (move_gap): Remove prototype.
971 * insdel.c (move_gap): Remove.
972 (move_gap_both): Add eassert.
973 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

976 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
978 emacsclient -t should not suspend Emacs server (Bug#13387)
979 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
981 * term.c (init_tty): Use them instead of rolling our own code.
982 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
983 switches from 'signal' to 'pthread_sigmask', which is safer in
984 multithreaded applications.
985 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
986 which has already arranged for that.
987 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
988 This is the main part of the bug fix.

1001 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1002 * buffer.c (buffer_slot_type_mismatch): Remove.
1003 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1004 predicate. Adjust comment.

1007 left-margin-width, right-margin-width, left-fringe-width,
1008 right-fringe-width, scroll-bar-width and buffer-display-count.
1009 Use Qstringp for default-directory, buffer-file-name,
1010 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1011 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1013 * data.c (store_symval_forwarding): Adjust to call the predicate.

1029 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1030 (make_gap_1): New function to adjust the gap of any buffer.
1031 * coding.c (coding_alloc_by_making_gap): Use it.
1032 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1033 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1035 2013-01-08 Juri Linkov <juri@jurta.org>
1037 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
1038 of (supports :underline (:style wave)). (Bug#13000)

1049 2013-01-06 Chong Yidong <cyd@gnu.org>
1051 * keyboard.c (echo_add_char): New function, factored out from
1052 echo_char. Don't add a space if the previous echo string was

1056 trailing dash is properly added.
1058 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1060 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1061 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1062 digits for buffer positions, before misalignment starts.
1063 Display "0" for integer "object" field.
1064 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1065 Display the newline glyph more unambiguously.
1067 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1069 * nsterm.m (ns_draw_underwave):
1070 * w32term.c (w32_draw_underwave):
1071 * xterm.c (x_draw_underwave): Make underwave look more triangular
1072 and also degrade gracefully for small fonts. (Bug#13000)
1074 * nsterm.m (ns_draw_text_decoration):
1075 * w32term.c (x_draw_glyph_string):
1076 * xterm.c (x_draw_glyph_string): Don't use previous underline
1077 thickness and position if previous underline type is underwave.
1079 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1081 * fileio.c (Ffile_acl): Undocument return format.
1083 2013-01-02 Glenn Morris <rgm@gnu.org>
1085 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
1087 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>

1095 * lread.c (read_list):
1096 * minibuf.c (Ftry_completion):
1097 * term.c (tty_ins_del_lines):
1098 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1099 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1101 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1103 * w32.c (unsetenv): Set up the string passed to _putenv
1105 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1106 for the bug this caused.
1108 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1110 * coding.c (Qmac): Now static.
1112 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1114 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1115 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1119 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1120 Show all on TOOLBAR_TOP_WIDGET.
1121 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1122 by TOOLBAR_TOP_WIDGET.
1123 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1124 Check toolbar_is_packed.
1125 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1127 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1129 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1130 (xg_update_menubar): Update title only if
1131 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1132 (xg_update_submenu): Skip tearoff only if
1133 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1134 (xg_initialize): Initialize xg_detached_menus only if
1135 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1137 * xterm.h (struct x_output): Surround handlebox_widget with
1138 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1139 toolbar_in_hbox is bool.
1141 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1143 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1144 (LIBS_GNUSTEP): Define.
1145 (LIBES): Add $(LIBS_GNUSTEP).
1146 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1148 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1150 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1151 continuation glyph on a TTY with an indication of an empty line.
1154 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1156 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1157 file's SELinux context or ACLs successfully set, nil otherwise.
1159 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1161 * w32proc.c (reader_thread): Avoid passing NULL handles to
1162 SetEvent and WaitForSingleObject.
1164 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1166 Port EXTERNALLY_VISIBLE to Clang 3.2.
1167 * conf_post.h (__has_attribute): New macro.
1168 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1170 2012-12-27 Glenn Morris <rgm@gnu.org>
1172 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1173 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1175 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1177 * fileio.c (file_name_as_directory, directory_file_name):
1178 Accept an additional argument MULTIBYTE to indicate whether the input C
1179 came from a multibyte or a unibyte Lisp string; all callers
1180 adjusted. Don't assume the input string is always multibyte.
1182 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1183 don't ENCODE_FILE them, and return a unibyte string if the input
1185 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1186 don't assume the input strings will always be multibyte. If the
1187 input strings are multibyte, decode strings obtained from C
1190 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1192 * lisp.h (toplevel): Add two notices to the comment about
1193 defining a new Lisp data type.

1197 * alloc.c (valid_lisp_object_p): Adjust comment.
1199 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1201 * keyboard.c (record_asynch_buffer_change): Initialize an event
1202 only if it's really needed.
1203 * frame.h (enum output_method): Remove output_mac member since
1204 it's a leftover from the deleted code.
1205 * frame.c (Fframep): Adjust user here ...
1206 * terminal.c (Fterminal_live_p): ... and here.
1207 * coding.c (Qmac): Now here because it's only used to denote
1208 end-of-line encoding type.
1209 (syms_of_coding): DEFSYM it.
1210 * frame.h (Qmac): Remove duplicated declaration.
1212 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1214 * window.c (select_window_1): Now static, since it's used only here.
1216 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1218 * window.c (window_body_cols): Subtract display margins from the
1219 window body width on TTYs as well. See
1220 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1221 for the original report.
1223 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1225 * xdisp.c (redisplay_window): Remove inner local variable
1226 because the outer shadowed one has the same meaning.
1227 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1229 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1230 (xg_create_tool_bar): Adjust users.
1232 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1234 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1235 * buffer.c (Fget_buffer_create): Use it to set compact field of
1236 struct buffer_text to avoid accessing an uninitialized value
1237 when compact_buffer is called for the first time.
1238 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1239 (Fset_buffer_modified_p): Use buffer_window_count to check
1240 whether the buffer is displayed in some window.
1241 * xdisp.c (message_dolog): Likewise.
1243 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1245 * w32.c (acl_set_file): If setting the file security descriptor
1246 fails, and the new DACL is identical to the existing one, silently
1247 return success. This fixes problems for users backing up their
1248 own files without having the necessary privileges for setting
1249 security descriptors.
1251 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1253 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1254 after WaitForSingleObject returns normally. This expedites reader
1255 thread shutdown when delete_child triggers it.
1256 (reap_subprocess): More accurate commentary for why we call
1257 delete_child only when cp->fd is negative.
1259 * w32.c (sys_close): Do not call delete_child on a subprocess
1260 whose handle is not yet closed. Instead, set its file descriptor
1261 to a negative value, so that reap_subprocess will call
1262 delete_child on that subprocess when its SIGCHLD arrives.
1263 This avoids closing handles used for communications between sys_select
1264 and reader_thread, which doesn't give sys_select a chance to
1265 notice that the process exited and invoke the SIGCHLD handler for
1268 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1270 * nsfns.m (Fns_do_applescript): Run event loop until script has
1271 been executed (Bug#12969).

1279 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1281 * w32term.c (w32fullscreen_hook): New function.
1282 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1284 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1286 * fileio.c (Finsert_file_contents): Doc fix.
1288 * w32proc.c (new_child, delete_child, find_child_pid): For a
1289 subprocess, consider its slot being in use as long as its process
1290 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1291 slot when a new process is started immediately after killing
1292 another one, without waiting enough time for the first process to
1293 be reaped and resources allocated for it be orderly freed.
1295 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1297 2012-12-21 Chong Yidong <cyd@gnu.org>
1299 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1301 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1303 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1305 * w32.c (get_name_and_id): Always pass NULL as the first argument
1306 of lookup_account_sid. Avoids crashes with UNC file names that
1307 refer to DFS domains, not to specific machine names. (Bug#12621)
1308 Remove now unused argument FNAME; all callers changed.
1309 (get_file_owner_and_group): Remove now unused argument FNAME; all
1312 2012-12-21 Chong Yidong <cyd@gnu.org>
1314 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1315 error for invalid chars, don't check for a nil return value.
1317 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1319 Avoid calls to CHAR_TO_BYTE if byte position is known.
1320 * editfns.c (make_buffer_string_both): Use move_gap_both.
1321 (Fbuffer_string): Use make_buffer_string_both.
1322 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1324 (buf_bytepos_to_charpos): Likewise.
1325 (charpos_to_bytepos): Remove.
1326 * fileio.c (Finsert_file_contents): Use move_gap_both.
1327 * search.c (Freplace_match): Likewise.
1328 * process.c (process_send_region): Likewise. Use convenient
1329 names for byte positions.
1330 * lisp.h (charpos_to_bytepos): Remove prototype.
1331 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1332 * insdel.c (move_gap): Likewise.

1338 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1340 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1341 (redisplay_internal): Don't bother selecting the frame to get the
1342 proper value of frame-local variables (bug#13225).
1344 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1346 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1347 Rename 4th argument since it may be buffer or string. Adjust comment.
1348 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1350 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1352 * coding.c (Fdetect_coding_region): Do not check start and end with
1353 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1354 (code_convert_region): Likewise.
1356 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1358 * w32.c (acl_get_file, acl_set_file): Run the file name through
1359 map_w32_filename, and resolve any symlinks in the file name, like
1361 (acl_set_file): Call revert_to_self, if any privileges were
1364 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1366 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1367 ($(BLD)/w32.$(O)): Update dependencies.
1369 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1371 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1372 propagate redisplay's scrolling (if any) to the right window.
1373 (redisplay_internal): Use ensure_selected_frame.
1374 (display_mode_lines): Complete last fix.
1375 * window.c (select_window_1): New func, extracted from select_window.
1376 (select_window): Use it.
1377 * window.h (select_window_1): Declare.
1379 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1381 Emulate Posix ACL APIs on MS-Windows.
1382 * w32.c: Include sddl.h and sys/acl.h.
1383 (SDDL_REVISION_1): Define if not already defined.

1401 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1403 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1405 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1406 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1407 for some of that bug's symptoms can now cause Emacs to abort.
1408 Remove the workaround.
1409 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1410 The bug that caused SIGCHLD to get lost has been fixed, and the
1411 workaround for it can now cause Emacs to abort.
1413 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1415 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1416 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1417 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1419 2012-12-16 Romain Francoise <romain@orebokech.com>
1421 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1422 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1423 and copy ACL entries of file in addition to SELinux context if set.
1424 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1426 * Makefile.in (LIBACL_LIBS): New macro.
1429 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
1431 * fileio.c (internal_delete_file): Use bool for boolean.
1433 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1435 Fix bug #13079 on MS-Windows with temp files not being deleted.
1436 * w32.h (_child_process): New members input_file and
1438 (register_child): First argument is now pid_t.
1439 (record_infile, record_pending_deletion): New prototypes.
1441 * w32proc.c (new_child): Initialize input_file and
1442 pending_deletion members of the child.
1443 (delete_child): Delete the child's temporary input file, if any,
1444 that is pending deletion.
1445 (register_child): First argument is now pid_t.
1446 (record_infile, record_pending_deletion): New functions.
1447 (reap_subprocess): Fix a typo in DebPrint string.
1448 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1450 * fileio.c (internal_delete_file): Return an int again: non-zero
1451 if delete-file succeeds, zero otherwise.
1453 * lisp.h (internal_delete_file): Adjust prototype.
1455 * callproc.c (Fcall_process): Don't overwrite infile with result
1457 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1458 asynchronous subprocess, record the name of the input file name,
1460 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1461 delete the file, record it as pending deletion when the subprocess
1464 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1466 * editfns.c [HAVE_PWD_H]: Include grp.h.
1468 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1470 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1472 Fix permissions bugs with setgid directories etc. (Bug#13125)
1473 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1474 to mark it as a placeholder. The old value was often wrong.
1475 The only user of this attribute has been changed to use
1476 file-ownership-preserved-p instead, with its new group arg.
1477 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1479 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1484 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1486 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1487 try to get accurate owner and group information from NT file
1488 security APIs. This is to make most callers of 'stat' and
1489 'lstat', which don't need that information, much faster.
1491 * dired.c (Ffile_attributes) [WINDOWSNT]:
1492 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1493 owner and group information from 'lstat'.
1495 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1497 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1498 as that confuses set-auto-coding, so insist on the head-read
1499 returning the full 1024 bytes. Let lseek compute the tail offset;
1500 less work for us. Do not ignore I/O errors when reading the tail.
1502 * xdisp.c: Minor style fixes.
1503 (init_iterator): Hoist assignment out of if-expression.
1504 (markpos_of_region): Callers now test for sign, not for -1.

1518 character in pattern when the buffer being searched is unibyte.
1521 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1523 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1524 files, fixing a regression from 24.2.
1525 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1527 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1529 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1530 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1531 Remove unnecessary S_ISLNK test, as (contra the comments) this
1532 function can't copy symlinks. Improve quality of error message
1533 when attempting to copy files that are neither regular files nor

1540 * window.c (Frecenter):
1541 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1542 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1544 2012-12-12 Daniel Colascione <dancol@dancol.org>
1546 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1547 the dumped Emacs is not a sparse file, greatly improving Cygwin
1548 "make bootstrap" performance.
1550 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1552 * inotify.c (inotify_callback): Generate an Emacs event for every
1553 incoming inotify event.
1555 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1557 * xdisp.c (handle_face_prop): Fix logic of computing
1558 it->start_of_box_run_p.
1559 (append_space_for_newline): If the glyph row is R2L, reset the
1560 iterator's end_of_box_run_p flag before prepending the space glyph.
1561 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1562 iterator's start_of_box_run_p flag before prepending the stretch.
1563 (append_glyph, produce_image_glyph, append_composite_glyph)
1564 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1565 left_box_line_p and right_box_line_p flags of the glyph for R2L
1566 glyph rows. (Bug#13011)

1580 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1581 encoded_file_name, which is what it is.
1583 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1609 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1612 * w32fns.c (cache_system_info): Initialize the global hinst
1613 variable here so various initialization calls DTRT.
1615 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1616 (hinst): Remove unneeded extern declaration.
1617 (_start): Remove initialization of above variables; remove
1618 initialization of hinst, as cache_system_info now does that.
1620 * emacs.c (main): Call cache_system_info early in startup; we
1621 previously weren't calling it in Cygwin builds.
1623 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):

1837 * frame.c (make_frame): Do not set window's buffer to t.
1838 * window.c (Fsplit_window_internal): Likewise. Previously it was
1839 used to indicate that the window is being set up. Now we use

1841 (Fset_window_buffer): ... is always true and can be removed.
1843 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1845 Convenient macro to check whether the buffer is hidden.

1874 New function, containing part of the old call_process_kill.
1875 (call_process_kill): Use it.
1876 This does not change call_process_kill's behavior.
1877 * process.c (Fdelete_process): Use record_kill_process to fix a
1878 race condition that could cause Emacs to lose track of a child.
1880 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1882 Avoid code duplication between prev_frame and next_frame.
1883 * frame.c (candidate_frame): New function. Add comment.

1888 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1889 fails, signal an error instead of continuing with an empty
1891 Encode expanded temp file pattern before passing it to mkstemp or
1894 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1895 Encode the file name before passing it to dostounix_filename, in
1896 case it will downcase it (under w32-downcase-file-names).
1899 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1901 Minor call-process cleanups.
1902 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1903 at the same time as other platforms, to simplify analysis.
1904 No need for fd0_volatile since we have synch_process_fd.
1905 Avoid needless emacs_close; arg is always negative.
1907 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1909 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1912 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1914 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1915 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1916 and mouse_face_hidden members to a bitfields.
1917 * frame.h (struct frame): Remove set-but-not-used space_width member.
1918 (FRAME_SPACE_WIDTH): Remove.
1919 * nsterm.m, w32term.c, xterm.c: Adjust users.
1920 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1921 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1922 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1923 members to a bitfields.
1925 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1927 Don't let call-process be a zombie factory (Bug#12980).
1928 Fixing this bug required some cleanup of the signal-handling code.
1929 As a side effect, this change also fixes a longstanding rare race
1930 condition whereby Emacs could mistakenly kill unrelated processes,
1931 and it fixes a bug where a second C-g does not kill a recalcitrant
1932 synchronous process in GNU/Linux and similar platforms.
1933 The patch should also fix the last vestiges of Bug#9488,
1934 a bug which has mostly been fixed on the trunk by other changes.
1935 * callproc.c, process.h (synch_process_alive, synch_process_death)
1936 (synch_process_termsig, sync_process_retcode):
1937 Remove. All uses removed, to simplify analysis and so that
1938 less consing is done inside critical sections.
1939 * callproc.c (call_process_exited): Remove. All uses replaced
1940 with !synch_process_pid.
1941 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1942 These take the role of what used to be in unwind-protect arg.
1944 (block_child_signal, unblock_child_signal):
1945 New functions, to avoid races that could kill innocent-victim processes.
1946 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1947 (call_process_kill): Record killed processes as deleted, so that
1948 zombies do not clutter up the system. Do this inside a critical
1949 section, to avoid a race that would allow the clutter.
1950 (call_process_cleanup): Fix code so that the second C-g works again
1951 on common platforms such as GNU/Linux.
1952 (Fcall_process): Create the child process in a critical section,
1953 to fix a race condition. If creating an asynchronous process,
1954 record it as deleted so that zombies do not clutter up the system.
1955 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1956 light of these changes. Omit unnecessary call to emacs_close
1957 before failure, as the unwind-protect code does that.
1958 * callproc.c (call_process_cleanup):
1959 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1960 * process.c (record_deleted_pid): New function, containing
1961 code refactored out of Fdelete_process.
1962 (Fdelete_process): Use it.
1963 (process_status_retrieved): Remove. All callers changed to use
1964 child_status_change.
1965 (record_child_status_change): Remove, folding its contents into ...
1966 (handle_child_signal): ... this signal handler. Now, this
1967 function is purely a handler for SIGCHLD, and is not called after
1968 a synchronous waitpid returns; the synchronous code is moved to
1969 wait_for_termination. There is no need to worry about reaping
1970 more than one child now.
1971 * sysdep.c (get_child_status, child_status_changed): New functions.
1972 (wait_for_termination): Now takes int * status and bool
1973 interruptible arguments, too. Do not record child status change;
1974 that's now the caller's responsibility. All callers changed.
1975 Reimplement in terms of get_child_status.
1976 (wait_for_termination_1, interruptible_wait_for_termination):
1977 Remove. All callers changed to use wait_for_termination.
1978 * syswait.h: Include <stdbool.h>, for bool.
1979 (record_child_status_change, interruptible_wait_for_termination):
1981 (record_deleted_pid, child_status_changed): New decls.
1982 (wait_for_termination): Adjust to API changes noted above.
1984 * bytecode.c, lisp.h (Qbytecode): Remove.
1985 No longer needed after 2012-11-20 interactive-p changes.
1987 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1989 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1990 the scroll margin, move point outside the margin. (Bug#13055)

1994 * gtkutil.c (my_log_handler): New function.
1995 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1997 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1999 * lisp.h (modify_region): Rename to...
2000 (modify_region_1): ...new prototype.
2001 * textprop.c (modify_region): Now static. Adjust users.
2002 * insdel.c (modify_region): Rename to...
2003 (modify_region_1): ...new function to work with current buffer.
2004 Adjust comment and users. Use true and false for booleans.
2006 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2008 * alloc.c (free_save_value): New function.
2009 (safe_alloca_unwind): Use it.
2010 * lisp.h (free_save_value): New prototype.
2011 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2013 (save_excursion_restore): Adjust to match saved data structure.
2014 Use free_save_value to offload some work from GC. Drop obsolete
2017 2012-12-03 Chong Yidong <cyd@gnu.org>
2019 * fileio.c (Vauto_save_list_file_name): Doc fix.
2021 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2023 * w32fns.c: Remove prototype of atof.
2024 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2026 (file_dialog_callback): Make it UINT_PTR.
2028 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2031 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2032 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2035 2012-12-03 Glenn Morris <rgm@gnu.org>
2037 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2039 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2041 Fix xpalloc confusion after memory is exhausted.
2042 * alloc.c (xpalloc): Comment fix.
2043 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2044 and signals an error, do not clear charset_table_size, as
2045 charset_table is still valid.
2046 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2048 Use execve to avoid need to munge environ (Bug#13054).
2049 * callproc.c (Fcall_process):
2050 * process.c (create_process):
2051 Don't save and restore environ; no longer needed.
2052 * callproc.c (child_setup):
2053 Use execve, not execvp, to preserve environ.
2055 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2057 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2059 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2061 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2062 display for sliced images (Bug#10500).
2064 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2066 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2068 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2069 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2071 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2073 * xdisp.c (window_outdated): Remove eassert since it hits
2074 some suspicious corner cases (see Bug#13007 and Bug#13012).
2075 (mode_line_update_needed): New function.
2076 (redisplay_internal, redisplay_window): Use it.
2077 (ensure_selected_frame): New function.
2078 (redisplay_internal, unwind_redisplay): Use it.
2079 (redisplay_internal): Move comment about buffer_shared...
2080 (buffer_shared_and_changed): ...near to its real use.
2082 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2084 * callproc.c (Fcall_process): Don't misreport vfork failure.
2086 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2088 * callproc.c (Fcall_process): Fix vfork portability problems.
2089 Do not assume that fd[0], count, filefd, and save_environ survive
2090 vfork. Fix bug whereby wrong errno value could be reported for
2091 pipe failure. Some minor cleanups, too, as follows. Move buf and
2092 bufsize to the context where they're needed. Change new_argv to
2093 be of type char **, as this is more convenient and avoids casts.
2094 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2095 Now local constants, not macros.
2097 2012-11-18 Kenichi Handa <handa@gnu.org>
2099 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2100 for the variable "f".

2104 * font.c (font_unparse_xlfd): Exclude special characters from the
2105 generating XLFD name.

2147 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2148 between bpos_covered and bpos_max. This fixes cursor display when
2149 several display strings follow each other.
2151 * .gdbinit (pgx): If the glyph's object is a string, display the
2152 pointer to string data, rather than the value of the string object
2153 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2155 * indent.c (Fvertical_motion): If the starting position is covered
2156 by a display string, return to one position before that, to avoid
2157 overshooting it inside move_it_to. (Bug#12930)

2184 * dired.c: Assume HAVE_DIRENT_H.
2185 (NAMLEN): Remove, replacing with ...
2186 (dirent_namelen): New function. All uses changed. Use the GNU macro
2187 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2188 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2189 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2190 * makefile.w32-in (DIR_H): Remove. All uses replaced with

2200 * xftfont.c (xftfont_open): Remove duplicate assignment.
2202 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2204 * alloc.c (Fgarbage_collect): Unblock input after clearing
2205 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2206 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2207 * msdos.c (IT_frame_up_to_date): Use it here...
2208 * w32term.c (w32_frame_up_to_date): ...here...

2250 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2252 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2254 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2255 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2256 Define for the MSVC compiler.
2258 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

2263 dostounix_filename assumes it gets a unibyte string.
2264 Reported by Michel de Ruiter <michel@sentient.nl>, see

2313 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2315 * w32select.c: Include w32common.h before w32term.h, so that
2316 windows.h gets included before w32term.h uses some of its
2317 features, see below.
2319 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2321 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2351 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2352 * nsterm.m: Assume <fcntl.h> exists.
2353 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2354 (create_pty, Fmake_network_process, server_accept_connection)
2355 (wait_reading_process_output, init_process_emacs):
2357 (wait_reading_process_output): Put in a special case for WINDOWSNT
2358 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2359 It's not clear this is needed, but it's a more-conservative change.
2360 (create_process): Assume FD_CLOEXEC.
2361 (create_process, create_pty): Assume O_NOCTTY.
2362 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2363 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2364 Omit if not DOS_NT, since F_GETFL is not defined there.
2365 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2366 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2368 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2369 lack it, since gnulib guarantees this.
2370 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2372 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2374 * w32.c (faccessat): Pretend that directories have the execute bit
2375 set. Emacs expects that, e.g., in files.el:cd-absolute.
2377 * w32proc.c (create_child): Don't clip the PID of the child
2378 process to fit into an Emacs integer, as this is no longer a
2380 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2381 reaping only the process specified by PID argument, if that is
2382 positive. Use PID instead of dead_child to know which process to
2383 reap. Wait for the child to die only if WNOHANG is not in
2385 (sys_select): Don't set dead_child.
2387 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2388 as it is no longer needed.
2390 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2392 (record_child_status_change): Remove the setting of
2393 record_at_most_one_child for the !WNOHANG case.
2395 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2397 Fix problems in ns port found by static checking.
2398 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2399 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2400 not to process group.
2401 (ns_select): Use emacs_write, not write, as that's more robust
2402 in the presence of signals.
2403 (fd_handler:): Check for read errors.
2405 2012-11-16 Glenn Morris <rgm@gnu.org>
2407 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2409 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2411 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2413 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2415 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2416 use the same value of thread handle.
2417 (start_timer_thread): If the timer thread exited (due to error),
2418 clean up by closing the two handles it used. Duplicate the caller
2419 thread's handle here, so it gets duplicated only once, when
2420 launching the timer thread. Set priority of the timer thread, not
2422 (getitimer): Don't duplicate the caller thread's handle here.
2425 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2427 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2430 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2432 Remove no-longer-used pty_max_bytes variable.
2433 * process.c (pty_max_bytes): Remove; unused.
2434 (send_process): Do not set it.
2436 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2438 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2439 Update dependencies.
2441 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2443 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2444 This follows up on the 2012-09-29 patch that removed indirection
2445 for the 'function' field. Reported by Sergey Vinokurov in
2446 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2448 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2450 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2451 different name, as the MS runtime does not have such a function,
2452 and probably never will.) All callers changed. Ignore DIRFD
2453 value if PATH is an absolute file name, to match Posix spec
2454 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2457 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2459 * xdisp.c (echo_area_display, redisplay_internal):
2460 Omit redundant check whether frame_garbaged is set.
2462 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2464 Use faccessat, not access, when checking file permissions (Bug#12632).
2465 This fixes a bug that has been present in Emacs since its creation.
2466 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2467 which must set some sort of record. (Torek's bug report was against
2468 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2469 same common flaw.) See Torek's Usenet posting
2470 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2471 Posted: Fri Apr 8 14:18:56 1983.
2472 * Makefile.in (LIB_EACCESS): New macro.
2474 * callproc.c (init_callproc):
2475 * charset.c (init_charset):
2476 * fileio.c (check_existing, check_executable, check_writable)
2478 * lread.c (openp, load_path_check):
2479 * process.c (allocate_pty):
2481 Use effective UID when checking permissions, not real UID.
2482 * callproc.c (init_callproc):
2483 * charset.c (init_charset):
2484 * lread.c (load_path_check, init_lread):
2485 Test whether directories are accessible, not merely whether they exist.
2486 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2487 * fileio.c (check_existing, check_executable, check_writable)
2489 Use symbolic names instead of integers for the flags, as they're
2491 (check_writable): New arg AMODE. All uses changed.
2492 Set errno on failure.
2493 (Ffile_readable_p): Use faccessat, not stat + open + close.
2494 (Ffile_writable_p): No need to call check_existing + check_writable.
2495 Just call check_writable and then look at errno. This saves a syscall.
2496 dir should never be nil; replace an unnecessary runtime check
2497 with an eassert. When checking the parent directory of a nonexistent
2498 file, check that the directory is searchable as well as writable, as
2499 we can't create files in unsearchable directories.
2500 (file_directory_p): New function, which uses 'stat' on most platforms
2501 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2502 (Ffile_directory_p, Fset_file_times): Use it.
2503 (file_accessible_directory_p): New function, which uses a single
2504 syscall for efficiency.
2505 (Ffile_accessible_directory_p): Use it.
2506 * xrdb.c (file_p): Use file_directory_p.
2507 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2508 * lread.c (openp): When opening a file, use fstat rather than
2509 stat, as that avoids a permissions race. When not opening a file,
2510 use file_directory_p rather than stat.
2511 (dir_warning): First arg is now a usage string, not a format.
2512 Use errno. All uses changed.
2513 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2514 that merely introduced a race.
2515 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2516 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2517 and similarly for the other O_* flags.
2518 * w32.c (sys_faccessat): Rename from sys_access and switch to
2519 faccessat's API. All uses changed.
2520 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2521 (magic_db): Rename from magic_file_p.
2522 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2523 char *, so that we don't have to test for file existence
2524 separately from opening the file for reading. This removes a race
2525 fixes a permission-checking problem, and simplifies the code.
2527 (file_p): Remove; no longer needed.
2529 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2531 Omit glyphs initialization at startup.
2532 * dispnew.c (glyphs_initialized_initially_p): Remove.
2533 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2534 (Fredraw_frame): Move actual code from here...
2535 (redraw_frame): ...to here. Add eassert. Adjust comment.
2536 (Fredraw_display): Use redraw_frame.
2537 * xdisp.c (clear_garbaged_frames): Likewise.
2539 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2541 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2542 passed to pint2str and pint2hrstr to be at most the size of the
2543 frame's decode_mode_spec_buffer. This avoids crashes with very
2544 large values of FIELD_WIDTH argument to decode_mode_spec.
2547 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2549 Fix a race with verify-visited-file-modtime (Bug#12863).
2550 Since at least 1991 Emacs has ignored an mtime difference of no
2551 more than one second, but my guess is that this was to work around
2552 file system bugs that were fixed long ago. Since the race is
2553 causing problems now, let's remove that code.
2554 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2555 whose time stamp is off by no more than a second. Insist that the
2556 file time stamps match exactly.
2558 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2560 * frame.h (struct frame): Convert external_tool_bar member to
2561 1-bit unsigned bitfield.
2562 * termhooks.h (struct terminal): Remove mouse_moved member since
2563 all users are long dead. Adjust comment on mouse_position_hook.
2565 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2567 Simplify by using FOR_EACH_FRAME here and there.
2568 * frame.c (next_frame, prev_frame, other_visible_frames)
2569 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2570 * w32term.c (x_window_to_scroll_bar): Likewise.
2571 * window.c (window_list): Likewise.
2572 * xdisp.c (x_consider_frame_title): Likewise.
2573 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2574 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2575 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2576 * xmenu.c (menubar_id_to_frame): Likewise.
2577 * xselect.c (frame_for_x_selection): Likewise.
2578 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2579 (x_window_to_menu_bar): Likewise.
2580 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2582 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2584 * data.c (Qdefalias_fset_function): Now static.
2586 Another tweak to vectorlike_header change.
2587 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2588 Remove, and replace all uses with ...
2589 (next_in_free_list, set_next_in_free_list):
2590 New functions, which respect C's aliasing rules better.
2592 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2594 * window.c (list4i): Rename from 'quad'. All uses changed.
2595 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2597 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2599 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2600 warning about mixing declarations and code in ISO C90.
2602 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2604 * window.c (Fsplit_window_internal): Set combination limit of
2605 new parent window to t iff Vwindow_combination_limit is t;
2606 fixing a regression introduced with the change from 2012-09-22.
2607 (Fset_window_combination_limit): Fix doc-string.
2609 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2611 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2612 amount when the scroll margins are too large. When scrolling
2613 backwards in the buffer, give up if cannot reach point or the
2614 scroll margin within a reasonable number of screen lines.
2615 Fixes point position in window under scroll-up/down-aggressively when
2616 point is positioned many lines beyond the window top/bottom.
2619 * ralloc.c (relinquish): If real_morecore fails to return memory
2620 to the system, don't crash; instead, leave the last heap
2621 unchanged and return. (Bug#12774)
2623 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2625 * lisp.h (AUTOLOADP): New macro.
2626 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2627 * data.c (Ffset): Remove special ad-advice-info handling.
2628 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2630 (Finteractive_form): Simplify.
2631 (Fquo): Don't insist on having at least 2 arguments.
2632 (Qdefalias_fset_function): New var.
2634 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2636 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2646 (SCROLL_BAR_VEC_SIZE): Remove.
2647 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2649 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2651 Tweak last vectorlike_header change.
2652 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2653 vectorlike object on the free list. This is introduced to avoid
2654 some (but not all) pointer casting and aliasing problems, see
2655 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2656 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2658 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2660 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2662 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2663 been removed, so remove them here also.
2665 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2667 * doc.c (Fdocumentation): Handle new property
2668 dynamic-docstring-function to replace the old ad-advice-info.

2681 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2683 Use same hash function for hashfn_profiler as for hash_string etc.
2684 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2685 * lisp.h (sxhash_combine): New inline function, with the contents
2686 of the old SXHASH_COMBINE.
2687 * profiler.c (hashfn_profiler): Use it, instead of having a
2688 special hash function containing a comparison that always yields 1.
2690 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2692 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)

2697 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2699 * image.c (xpm_make_color_table_h): Fix compiler error because

2709 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2710 (make_log): Use them.

2735 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2736 value of w32-scroll-lock-modifier is neither nil nor one of the
2737 known key modifiers. (Bug#12806)
2739 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>

2742 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2744 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

2763 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2764 (large_vectors): Change type to struct large_vector.
2765 (allocate_vector_from_block): Simplify.
2766 (PSEUDOVECTOR_NBYTES): Replace with...

2778 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2779 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2780 (copy_hash_table): Adjust to match vector header change.
2781 * lread.c (defsubr): Use XSETPVECTYPE.
2782 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2783 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2784 (xvecsize): New command.
2786 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2788 * keyboard.c (event_to_kboard): Do not dereference
2789 frame_or_window field of SELECTION_REQUEST_EVENT
2790 and SELECTION_CLEAR_EVENT events (Bug#12814).
2791 * xterm.h (struct selection_input_event): Adjust comment.
2793 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2795 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2796 such as Scroll Lock, if the respective keys are treated as
2797 function keys, not as modifiers. This avoids destroying non-ASCII
2798 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2800 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2802 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2804 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2806 Restore some duplicate definitions (Bug#12814).
2807 This undoes part of the 2012-11-03 changes. Some people build
2808 with plain -g rather than with -g3, and they need the duplicate
2809 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2810 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2811 Define as macros, as well as as enums or as constants.
2813 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2815 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2816 to keypad keys (Bug#12816).
2818 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2820 Minor adjustments of recently-changed frame functions.
2821 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2822 known to be a frame (we're in the FRAMEP branch).
2823 * lisp.h (Qframep): Remove decl. frame.h declares this.
2824 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2825 since they're meant for Lisp fixnum values.
2827 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2829 * window.c (Fwindow_combination_limit): Revert to the only
2830 required argument and adjust docstring as suggested in
2831 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2832 by Martin Rudalics <rudalics@gmx.at>.
2834 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2836 Widely used frame validity and checking functions.
2837 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2838 * frame.c (decode_live_frame, decode_any_frame): New functions.
2839 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2840 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2841 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2842 (Fframe_pointer_visible_p): Use decode_any_frame.
2843 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2844 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2845 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2846 (Fframe_focus): Likewise. Allow zero number of arguments.
2848 (frame_buffer_list, frame_buffer_predicate): Remove.
2849 * lisp.h (frame_buffer_predicate): Remove prototype.
2850 * buffer.c (Fother_buffer): Use decode_any_frame.
2851 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2852 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2853 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2854 (Fclose_font, Ffont_info): Use decode_live_frame.
2855 * fontset.c (check_fontset_name): Likewise.
2856 * terminal.c (Fframe_terminal): Likewise.
2857 * w32fns.c (check_x_frame): Likewise.
2858 * window.c (Fminibuffer_window, Fwindow_at)
2859 (Fcurrent_window_configuration): Likewise.
2860 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2861 Likewise. Allow zero number of arguments. Adjust docstring.
2862 * dispnew.c (Fredraw_frame): Likewise.
2863 * xfaces.c (frame_or_selected_frame): Remove.
2864 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2865 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2866 (Fframe_face_alist): Use decode_live_frame.
2867 * xfns.c (check_x_frame): Likewise.
2869 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2871 * window.c (quad): New function.
2872 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2873 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2874 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2875 (Fwindow_line_height): Use it.
2876 (Fwindow_fringes): Use list3.
2877 (Fwindow_scroll_bars): Use list4.
2878 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2879 (Fwindow_combination_limit): Allow zero number of arguments.
2881 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2883 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2885 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2886 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2887 file descriptor 2 for standard error. (Bug#12805)
2889 2012-11-05 Chong Yidong <cyd@gnu.org>
2891 * process.c (wait_reading_process_output): Revert previous change.
2893 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2895 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2896 This removes code that has been obsolete since around 1990.
2897 * callproc.c (Fcall_process):
2899 * process.c (create_process):
2900 * term.c (dissociate_if_controlling_tty):
2901 Assume setsid exists.
2902 * callproc.c (child_setup): Assume setpgid exists and behaves as
2903 per POSIX.1-1988 or later.
2904 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2905 * emacs.c (shut_down_emacs):
2906 * sysdep.c (sys_suspend, init_foreground_group):
2907 Assume getpgrp behaves as per POSIX.1-1998 or later.
2908 * msdos.c (setpgrp): Remove.
2909 (tcgetpgrp, setpgid, setsid): New functions.
2910 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2911 * term.c (no_controlling_tty): Remove; unused.
2912 * w32proc.c (setpgrp): Remove.
2913 (setsid, tcgetpgrp): New functions.
2915 Simplify by assuming __fpending.
2916 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2917 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2918 Do not assume that __fpending's result fits in int.
2920 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2922 Remove EMACS_OUTQSIZE+sleep hack.
2923 * dispnew.c (update_frame_1): Remove hack for terminals slower
2924 than 2400 bps, which throttled Emacs by having it sleep.
2925 This code hasn't worked since at least 2007, when the multi-tty stuff
2926 was added, and anyway those old terminals are long dead.
2927 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2928 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2930 Fix data-loss with --version (Bug#9574).
2931 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2932 as we can't assume that emacs_strerror is initialized, and strerror
2933 is good enough here.
2934 (main): Invoke atexit earlier, to catch earlier instances of
2935 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2937 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2939 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2940 (keyDown): Remap keypad keys to X11 virtual key codes.
2942 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2944 Fix data-loss with --batch (Bug#9574).
2945 * emacs.c: Include <close-stream.h>.
2946 (close_output_streams): New function.
2947 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2948 and handles errors appropriately.
2949 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2952 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2953 The symptom is a diagnostic "GLib-WARNING **: In call to
2954 g_spawn_sync(), exit status of a child process was requested but
2955 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2956 waitpid(), so exit status can't be returned." The diagnostic
2957 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2958 The real bug is a race condition between Emacs and glib: Emacs
2959 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2960 so that glib can't find it. Work around the bug by invoking
2961 waitpid only on subprocesses that Emacs itself creates.
2962 * process.c (create_process, record_child_status_change):
2963 Don't use special value -1 in pid field, as the caller now must
2964 know the pid rather than having the callee infer it.
2965 The inference was sometimes incorrect anyway, due to another race.
2966 (create_process): Set new 'alive' member if child is created.
2967 (process_status_retrieved): New function.
2968 (record_child_status_change): Use it.
2969 Accept negative 1st argument, which means to wait for the
2970 processes that Emacs already knows about. Move special-case code
2971 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2972 processes that have already been waited for, by testing and
2973 clearing new 'alive' member.
2974 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2975 now does this internally.
2976 (handle_child_signal): Let record_child_status_change do all
2977 the work, since we do not want to reap all exited child processes,
2978 only the child processes that Emacs itself created.
2979 * process.h (Lisp_Process): New boolean member 'alive'.
2981 Omit duplicate definitions no longer needed with gcc -g3.
2982 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2983 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2984 Define only as macros. There's no longer any need to also define
2985 these symbols as enums or as constants, since we now assume
2986 gcc -g3 when debugging.
2988 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2990 * lisp.mk: Adjust comments to the fact that term/internal is now
2991 loaded from loadup.el.
2993 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2994 (msdos_fatal_signal): New function.
2995 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2998 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2999 for GCC versions before 4.
3000 (emacs_raise): Define to call msdos_fatal_signal.
3002 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3003 iterator when starting in the middle of a display or overlay
3006 2012-11-03 Chong Yidong <cyd@gnu.org>
3008 * process.c (wait_reading_process_output): Clean up the last
3011 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3013 * process.c (wait_reading_process_output): Avoid a race condition
3014 with SIGIO delivery (Bug#11536).
3016 2012-11-03 Chong Yidong <cyd@gnu.org>
3018 * buffer.c (cursor_type): Untabify docstring.
3020 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3022 * frame.h (struct frame): Drop can_have_scroll_bars member
3023 which is meaningless for a long time. Adjust comments.
3024 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3025 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3027 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3029 * window.c (decode_next_window_args): Update window arg after
3030 calling decode_live_window and so fix crash reported at
3031 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3032 by Juanma Barranquero <lekktu@gmail.com>.
3033 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3034 * font.c (Ffont_at): Likewise.
3036 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3038 * widget.c (resize_cb): New function.
3039 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3040 (EmacsFrameResize): Check if all is up to date before changing frame
3043 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3045 Implement backtrace output for fatal errors on MS-Windows.
3046 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3047 (BACKTRACE_LIMIT_MAX): New macro.
3048 (w32_backtrace): New function.
3049 (emacs_abort): Use w32_backtrace when the user chooses not to
3050 attach a debugger. Update the text of the abort dialog.
3052 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3054 Window-related stuff cleanup here and there.
3055 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3056 Use decode_any_window.
3057 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3058 * xdisp.c (Fformat_mode_line): Likewise.
3059 * font.c (Ffont_at): Use decode_live_window.
3060 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3061 * window.c (decode_next_window_args): Likewise.
3062 (decode_any_window): Remove static.
3063 * window.h (decode_any_window): Add prototype.
3064 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3065 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3068 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3070 Remove pad from struct input_event.
3071 * termhooks.h (struct input_event): Remove padding field.
3073 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3074 member is never cons for a long time. Adjust comment.
3075 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3076 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3077 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3078 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3080 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3082 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3084 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3086 Fix crash when using Emacs as commit editor for git (Bug#12697).
3087 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3088 and it is configured in conf_post.h.
3089 (Fcall_process): Don't invoke both setsid and setpgid; the former
3090 is enough, if it exists.
3091 * callproc.c (Fcall_process, child_setup):
3092 * process.c (create_process): Use setpgid.
3093 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3095 * dispnew.c (init_display): Initialize the foreground group
3096 if we are running a tty display.
3097 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3098 * lisp.h (init_foreground_group): New decl.
3099 * sysdep.c (inherited_pgroup): New static var.
3100 (init_foreground_group, tcsetpgrp_without_stopping)
3101 (narrow_foreground_group, widen_foreground_group): New functions.
3102 (init_sys_modes): Narrow foreground group.
3103 (reset_sys_modes): Widen foreground group.
3105 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3107 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3109 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3111 * minibuf.c (read_minibuf): Restore current buffer since
3112 choose_minibuf_frame calling Fset_frame_selected_window may
3113 change it (Bug#12766).
3115 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3117 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3119 2012-10-30 Kenichi Handa <handa@gnu.org>
3121 * font.c (Ffont_at): If WINDOW is specified and it is not
3122 displaying the current buffer, signal an error.
3124 2012-10-29 Daniel Colascione <dancol@dancol.org>
3126 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3127 In preparation for fixing bug#12739, move these functions from
3130 * coding.h, coding.c: ... to here, and compile them only when
3131 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3132 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3134 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3136 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3137 (timer_loop, getitimer, setitimer): Use it instead of
3138 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3140 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3143 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3145 * nsterm.m (NO_APPDEFINED_DATA): New define.
3146 (last_appdefined_event_data): New variable
3147 (last_appdefined_event): Remove.
3148 (ns_select): Initialize t from last_appdefined_event_data instead
3149 of [last_appdefined_event data1].
3150 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3151 remove last_appdefined_event (Bug#12698).
3153 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3155 * frame.c (x_set_font): Catch internal error.
3157 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3159 Avoid overflow in w32 implementation of interval timers.
3160 When possible, for ITIMER_PROF count only times the main thread
3162 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3163 'volatile ULONGLONG' types. All the other data which was
3164 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3165 (GetThreadTimes_Proc): New typedef.
3166 (w32_get_timer_time): New function, returns a suitable time value
3168 (timer_loop): Enter critical section when accessing ULONGLONG
3169 values of the itimer_data struct, as these accesses are no longer
3170 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3171 Remove unused variable.
3172 (init_timers): Initialize s_pfn_Get_Thread_Times.
3173 (start_timer_thread): Don't assign itimer->caller_thread here.
3174 (getitimer): Assign itimer->caller_thread here.
3175 (setitimer): Always call getitimer to get the value of ticks_now.
3176 (sys_spawnve): Avoid compiler warning about format mismatch.
3178 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3180 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3181 mouse movement events if the menu bar is active. This avoids
3182 producing a busy "hour-glass" cursor by Windows if the mouse
3183 pointer is positioned over a tooltip shown for some menu item.
3185 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3187 Don't assume process IDs fit in int.
3188 * emacs.c (shut_down_emacs) [!DOS_NT]:
3189 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3190 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3191 Use pid_t, not int, to store process IDs, as 'int'
3192 is not wide enough on a few platforms (e.g., AIX and IRIX).
3194 2012-10-23 Kenichi Handa <handa@gnu.org>
3196 The following change is to make face-font-rescale-alist work
3197 correctly for non-ASCII fonts.
3199 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3200 (font_open_for_lface): Handle Vface_font_rescale_alist.
3202 2012-10-23 Chong Yidong <cyd@gnu.org>
3204 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3206 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3208 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3210 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3212 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3215 2012-10-21 Glenn Morris <rgm@gnu.org>
3217 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3219 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3221 Port to OpenBSD 5.1.
3222 * frame.c (Fmouse_position, Fmouse_pixel_position):
3223 * xdisp.c (produce_stretch_glyph):
3224 Declare local vars only when they're needed.
3225 This is clearer and avoids a warning on OpenBSD about unused vars.
3226 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3227 This is safer, and avoids OpenBSD warnings about unused vars.
3228 * keyboard.c (record_menu_key): Remove unnecessary decl.
3229 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3230 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3231 as our definition clashes with OpenBSD's.
3232 * xfaces.c (load_face_colors, check_lface_attrs)
3233 (get_lface_attributes_no_remap, get_lface_attributes)
3234 (lface_fully_specified_p, x_supports_face_attributes_p)
3235 (tty_supports_face_attributes_p, face_fontset, realize_face)
3236 (realize_x_face, realize_tty_face):
3237 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3238 merely Lisp_Object *. This is more informative and avoids

3721 (Fcygwin_convert_path_to_windows)
3722 (Fcygwin_convert_path_from_windows): New user functions for
3723 accessing Cygwin path-munging routines.
3725 * cygw32.h: New file.
3726 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3727 UTF-16LE strings temporarily inside non-Lisp-visible string
3730 (w32_strerror): Just what it says on the tin.
3732 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3733 also run for Cygwin; both systems have the same problem with using
3734 GUI facilities in a forked child. Also call syms_of_cygw32,
3735 syms_of_w32select in correct places.
3737 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3738 needs fork-then-exec for daemon launching.
3740 * font.h: Include frame.h.
3742 * image.c: Use the image library cache machinery only when we're
3743 compiling for native WINDOWSNT; Cygwin can use shared libraries
3744 like any other Unixlike system.
3746 * keyboard.c: Clarify a comment regarding the input loop.
3748 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3749 functions directly instead of trying to detect at runtime that our
3750 host operating system supports them. We make this change for two
3751 reasons: Cygwin lacks support for the multibyte character
3752 conversion functions used by the legacy menu code, and Cygwin
3753 never needs to rely on non-Unicode APIs.
3755 * unexw32.c (hinst): Declare extern.
3757 * w32.c: Change header order;
3758 (w32_strerror): Move to w32fns.c because we need it for
3759 non-WINDOWSNT builds.
3761 * w32.h: Add #error macro to make sure we don't include w32.h for
3762 Cygwin builds. Remove w32select declarations.
3764 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3765 w32fns.c. w32console.c is WINDOWSNT-only.
3767 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3768 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3770 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3771 (w32_major_version, w32_minor_version, w32_build_number)
3772 (os_subtype, sound_type): Define here
3773 (w32_defined_color): Make color parameter const for consistency
3774 with other _defined_color functions.
3775 (w32_createwindow): Unconditionally call w32_init_class instead of
3776 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3777 through the code is complex and unnecessary because class
3778 registration is practically free.
3779 (w32_name_of_message): New EMACSDEBUG-only function.
3780 (Fset_message_beep): Move here
3781 (Fx_open_connection): Require that the display name for Windows be
3782 "w32" for consistency, emacsclient disambiguation, and maybe, one
3783 day, multi-window-system support.
3784 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3785 Cygwin files for W32 GUI facilities, since these clearly don't
3786 expect Cygwin names.
3787 (_DebPrint): Define.
3788 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3789 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3790 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3791 (w32_last_error): Remove.
3793 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3795 * w32heap.c (syspage_mask): Declare here.
3796 (cache_system_info): Remove.
3798 * w32inevt.c (faked_key): Define globally, not statically.
3799 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3800 (w32_console_toggle_lock_key): Move to w32fns.c.
3802 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3804 * w32proc.c (_DebPrint): Move to w32fns.c.
3805 * w32select.c: Include string.h, stdio.h for Cygwin.
3806 * w32select.h: New File.
3808 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3810 (w32_message_fd): New variable. Under Cygwin, holds the file
3811 descriptor the system used to tell us about pending thread
3814 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3815 that prevented compilation under non-WINDOWSNT systems.
3817 (w32_initialize): Open /dev/windows and assign it to
3818 w32_message_fd. Provide w32 feature.
3820 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3821 (WM_EMACS_INPUT_READY): add.
3822 (prepend_msg, w32_message_fd): Declare globally.
3825 (keyboard_handle): Use only when WINDOWSNT.
3826 (notify_msg_ready): New function. Posts a message to the main
3827 thread's message queue under CYGWIN, which wakes up the main
3828 thread from select(2) by making the /dev/windows file descriptor
3829 ready. Under WINDOWSNT, it sets an event the same way the old
3832 (post, prepend_msg): Actually call notify_msg_ready instead of
3833 setting the input event directly.
3835 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3837 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3838 but it still has blocs in it, don't return it to the system,
3839 instead of aborting. (Bug#12402)
3841 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3843 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3845 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3846 MAC_OS_X_VERSION_10_6.
3847 (syms_of_nsterm): Remove comment about Panther and above for
3849 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3850 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3851 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3853 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3854 MAC_OS_X_VERSION_10_4.
3856 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3857 MAC_OS_X_VERSION_10_2.
3859 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3861 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3862 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3864 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3865 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3866 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3867 Remove ns_in_resize check.
3868 (ns_clear_frame_area): Remove resize handle code.
3870 * nsfns.m (ns_in_resize): Remove.
3871 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3872 Remove ns_in_resize check.
3874 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3876 Improve sys_siglist detection.
3877 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3878 defined as a macro, as is done in Solaris.
3879 (sys_siglist_entries): New macro.
3880 (save_strsignal): Use it.
3881 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3882 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3884 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3886 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3887 fullscreen/Fullscreen.
3889 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3890 tobar_height is new.
3892 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3893 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3894 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3895 (windowDidResize:): Check for correct window if old style fullscreen.
3896 Capitalize word in comment. Remove incorrect comment.
3897 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3898 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3899 error in drawing background.
3900 (toggleFullScreen:): Remove comment. Rearrange calls.
3901 Set toolbar values to zero, save old height in tobar_height.
3902 Restore tool bar height when leaving fullscreen.
3903 (canBecomeMainWindow): New function.
3905 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3907 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3909 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3911 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3913 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3914 that time stamps of directories could also be changed.
3915 Don't request the too broad GENERIC_WRITE, only the more restrictive
3916 FILE_WRITE_ATTRIBUTES access rights.
3918 * fileio.c (Fset_file_times): Special-case ignoring errors for
3919 directories only on MSDOS, not on MS-Windows.
3921 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3923 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3925 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3927 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3928 see whether CreateFile failed.
3930 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3932 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3933 to avoid similar races.
3934 * keyboard.c (pending_signals): Now bool, not int.
3936 Port timers to OpenBSD, plus check for timer failures.
3937 OpenBSD problem reported by Han Boetes.
3938 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3940 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3941 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3942 like OpenBSD, which has timer_settime but does not declare it.
3943 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3944 whether to use itimerspec-related primitives. All uses of
3945 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3947 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3949 * profiler.c (handle_profiler_signal): Fix a malloc race
3950 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3952 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3954 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3956 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3958 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3959 consistent with the change in return value of 'safe_strsignal'.
3961 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3963 Prefer plain 'static' to 'static inline' (Bug#12541).
3964 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3965 (bidi_set_sor_type, bidi_push_embedding_level)
3966 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3967 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3968 (bidi_cache_search, bidi_cache_ensure_space)
3969 (bidi_cache_iterator_state, bidi_cache_find)
3970 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3971 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3972 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3973 Now 'static', not 'static inline'.
3975 Count overruns when profiling; change units to ns.
3976 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3977 Give extra weight to samples after overruns, to attempt to count
3978 the time more accurately.
3979 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3980 the underlying primitives nominally do ns.
3981 (Fprofiler_cpu_start): Document the change. Mention that
3982 the sampling intervals are only approximate.
3984 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3986 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3988 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3989 case for the special 0 coding-system.
3991 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3992 (Fmake_overlay): Remove redundant tests.
3993 (fix_start_end_in_overlays): Remove redundant recentering.
3995 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3997 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3998 Update dependencies.
4000 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4002 Fix a malloc race condition involving strsignal.
4003 A signal can arrive in the middle of a malloc, and Emacs's signal
4004 handler can invoke strsignal, which can invoke malloc, which is
4005 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4006 Fix it by altering the signal handler so that it does not invoke
4008 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4009 * process.c (status_message): Use const pointer, in case strsignal
4010 is #defined to safe_strsignal.
4011 * sysdep.c (sys_siglist, init_signals): Always define and
4012 initialize a substitute sys_siglist if the system does not define
4013 one, even if HAVE_STRSIGNAL.
4014 (safe_strsignal): Rename from strsignal. Always define,
4015 using sys_siglist. Return a const pointer.
4016 * syssignal.h (safe_strsignal): New decl.
4017 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4019 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4021 * w32proc.c (timer_loop): Fix code that waits for timer
4022 expiration, to avoid high CPU usage.
4024 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4026 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4027 (sweep_weak_table): Remove redundant prototypes.
4029 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4031 * emacs.c: Move the inclusion of TERM_HEADER after including
4032 windows.h on WINDOWSNT. This avoids compilation problems with
4035 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4037 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4038 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4039 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4040 as the previous version used 'void *'.
4042 * ralloc.c (ROUNDUP): Fix last change.
4043 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4046 * w32proc.c <disable_itimers>: New static flag.
4047 (init_timers): Initialize it to zero, after creating the critical
4048 sections used by the timer threads.
4049 (term_timers): Set to 1 before deleting the critical sections.
4050 (getitimer, setitimer): If disable_itimers is non-zero, return an
4051 error indication without doing anything. Reported by Fabrice
4052 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4053 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4055 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4058 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4059 term_ntproc after all the other bookkeeping, to get timers working
4060 as long as possible.
4062 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4064 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4065 Suggested by Juri Linkov in
4066 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4068 Prefer plain 'static' to 'static inline' (Bug#12541).
4069 With static functions, modern compilers inline pretty well by
4070 themselves; advice from programmers often hurts as much as it helps.
4071 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4072 this change shrinks the text size of the Emacs executable by 1.1%
4073 without affecting CPU significantly in my benchmark.
4074 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4075 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4149 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
4150 Now 'static', not 'static inline'.
4153 (bidi_copy_it): Do the whole copy with a single memcpy.
4154 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4156 Revert the FOLLOW-SYMLINKS change for file-attributes.
4157 Doing it right would require several changes to Tramp, and there's
4158 not enough time to get that tested before the freeze today.

4367 (handle_profiler_signal): Rename from sigprof_handler_1,
4368 for consistency with other handlers. Do not check whether
4369 cpu_log is a hash-table if garbage collecting, since it

4372 for consistency with other handlers.
4373 (setup_cpu_timer): New function, with much of what used to be in

4375 Prefer timer_settime if available, and prefer
4376 thread cputime clocks, then process cputime clocks, then
4377 monotonic clocks, to the old realtime clock. Use make_timeval
4378 to round more-correctly when falling back to setitimer.
4379 (Fprofiler_cpu_start): Use it.
4380 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4387 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4388 in profiler.c, since sysdep.c now uses it.
4390 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4446 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4447 Since this stuff is now private to charset.c, there's no need for
4448 a public macro and no need to inline by hand.

4522 (sys_kill): Improve commentary.
4524 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4525 consistency with a signature of a signal handler. All callers

4528 install term_ntproc as a signal handler for SIGABRT, as that
4529 should be done by the dumped Emacs.

4624 Use bool for boolean.
4625 * gtkutil.c (xg_update_frame_menubar):

4631 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4633 * makefile.w32-in (BLOCKINPUT_H): Remove.

4650 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4652 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4653 fatal_error_backtrace.
4655 * w32proc.c (sys_kill): Undo last change: don't do anything when
4656 invoked to deliver SIGABRT to our own process. This is now
4657 handled by emacs_raise.
4659 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4661 * w32term.c (w32_read_socket): Remove leftover reference to
4662 interrupt_input_pending.
4664 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4666 Do not use SA_NODEFER.
4667 Problem reported by Dani Moncayo in
4668 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4670 * sysdep.c (emacs_abort): Do not reset signal handler.
4671 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4672 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4673 wanted even on POSIXish hosts, and it doesn't work on Windows.
4675 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4677 * xterm.c (x_term_init): Call fixup_locale before and after calling
4678 gtk_init (Bug#12392).
4680 2012-09-23 Chong Yidong <cyd@gnu.org>
4682 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4683 Vdynamic_library_alist.
4685 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4686 (Fgnutls_available_p): Caller changed.
4688 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4689 (Flibxml_parse_xml_region): Likewise.
4691 * dispextern.h (struct image_type): Remove arg from init function.
4693 * image.c (Finit_image_library, lookup_image_type)
4694 (define_image_type): Remove now-unneeded second arg.
4695 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4696 (init_tiff_functions, init_gif_functions, init_svg_functions):
4697 Arglist and w32_delayed_load calling convention changed.
4698 (gs_type): Remove init_gs_functions; there is no such function.
4699 (valid_image_p, make_image): Fix caller to lookup_image_type.
4701 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4703 Simplify and avoid signal-handling races (Bug#12471).
4705 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4706 Avoid recursive loop if there's a fatal error in the function itself.
4707 * atimer.c (pending_atimers):
4708 * blockinput.h: Don't include "atimer.h"; no longer needed.
4709 (interrupt_input_pending): Remove. All uses removed.
4710 pending_signals now counts both atimers and ordinary interrupts.
4711 This is less racy than having three separate pending-signal flags.
4712 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4714 Rename from their upper-case counterparts BLOCK_INPUT,
4715 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4716 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4717 This makes it easier to access volatile variables more accurately.
4718 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4719 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4720 that's more reliable if the code is buggy and sets
4721 interrupt_input_blocked to a negative value. All uses changed.
4722 * atimer.c (deliver_alarm_signal):
4723 Remove. No need to deliver this to the parent; any thread can
4724 handle this signal now. All uses replaced by underlying handler.
4725 * atimer.c (turn_on_atimers):
4726 * dispnew.c (handle_window_change_signal):
4727 * emacs.c (handle_danger_signal):
4728 * keyboard.c (kbd_buffer_get_event):
4729 Don't reestablish signal handler; not needed with sigaction.
4730 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4732 Rework to avoid unnecessary accesses to volatile variables.
4733 (UNBLOCK_INPUT_TO): Now a function.
4734 (totally_unblock_input, unblock_input): New decls.
4735 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4736 (init_data): Remove. Necessary stuff now done in init_signal.
4737 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4738 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4739 (fatal_error_code): Remove; no longer needed.
4740 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4741 it doesn't always backtrace. All uses changed. No need to reset
4742 signal to default, since sigaction and/or die does that for us now.
4743 Use emacs_raise (FOO), not kill (getpid (), FOO).
4744 (main): Check more-accurately whether we're dumping.
4745 Move fatal-error setup to sysdep.c
4746 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4747 * gtkutil.c (xg_get_file_name, xg_get_font):
4748 Remove no-longer-needed signal-mask manipulation.
4749 * keyboard.c, process.c (POLL_FOR_INPUT):
4750 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4751 * keyboard.c (read_avail_input): Remove.
4752 All uses replaced by gobble_input.
4753 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4754 (kbd_buffer_store_event_hold, gobble_input):
4755 (record_asynch_buffer_change) [USABLE_SIGIO]:
4756 (store_user_signal_events):
4757 No need to mess with signal mask.
4758 (gobble_input): If blocking input and there are terminals, simply
4759 set pending_signals to 1 and return. All hooks changed to not
4760 worry about whether input is blocked.
4761 (process_pending_signals): Clear pending_signals before processing
4762 them, in case a signal comes in while we're processing.
4763 By convention callers now test pending_signals before calling us.
4764 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4765 New functions, to support changes to blockinput.h.
4766 (handle_input_available_signal): Now extern.
4767 (reinvoke_input_signal): Remove. All uses replaced by
4769 (quit_count): Now volatile, since a signal handler uses it.
4770 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4771 All callers changed. Block SIGINT only if not already blocked.
4772 Clear sigmask reliably, even if Fsignal returns, which it can.
4773 Omit unnecessary accesses to volatile var.
4774 (quit_throw_to_read_char): No need to restore sigmask.
4775 * keyboard.c (gobble_input, handle_user_signal):
4776 * process.c (wait_reading_process_output):
4777 Call signal-handling code rather than killing ourselves.
4778 * lisp.h: Include <float.h>, for...
4779 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4780 (pending_signals): Now volatile.
4781 (syms_of_data): Now const if IEEE floating point.
4782 (handle_input_available_signal) [USABLE_SIGIO]:
4783 (terminate_due_to_signal, record_child_status_change): New decls.
4784 * process.c (create_process): Avoid disaster if memory is exhausted
4785 while we're processing a vfork, by tightening the critical section
4787 (send_process_frame, process_sent_to, handle_pipe_signal)
4788 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4790 (send_process): No need for setjmp/longjmp any more, since the
4791 SIGPIPE stuff is now gone. Instead, report an error if errno
4793 (record_child_status_change): Now extern. PID and W are now args.
4794 Return void, not bool. All callers changed.
4795 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4796 Remove. All uses removed. This bug should be fixed now in a
4798 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4799 and record the child status change directly. This avoids the
4800 need to futz with the signal mask.
4801 (process_fatal_action): Move here from emacs.c.
4802 (emacs_sigaction_flags): New function, containing
4803 much of what used to be in emacs_sigaction_init.
4804 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4805 caught by emacs, to make races less likely.
4806 (deliver_process_signal): Rename from handle_on_main_thread.
4808 (BACKTRACE_LIMIT_MAX): Now at top level.
4809 (thread_backtrace_buffer, threadback_backtrace_pointers):
4811 (deliver_thread_signal, deliver_fatal_thread_signal):
4812 New functions, for more-accurate delivery of thread-specific signals.
4813 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4814 (deliver_arith_signal): Handle in this thread, not
4815 in the main thread, since it's triggered by this thread.
4816 (maybe_fatal_sig): New function.
4817 (init_signals): New arg DUMPING so that we can be more accurate
4818 about whether we're dumping. Caller changed.
4819 Treat thread-specific signals differently from process-general signals.
4820 Block all signals while handling fatal error; that's safer.
4821 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4823 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4824 Ignore SIGPIPE unless batch.
4825 (emacs_backtrace): Output backtrace for the appropriate thread,
4826 which is not necessarily the main thread.
4827 * syssignal.h: Include <stdbool.h>.
4828 (emacs_raise): New macro.
4829 * xterm.c (x_connection_signal): Remove; no longer needed
4830 now that we use sigaction.
4831 (x_connection_closed): No need to mess with sigmask now.
4832 (x_initialize): No need to reset SIGPIPE handler here, since
4833 init_signals does this for us now.
4835 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4837 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4838 background rect may be larger (Bug#12245).
4840 2012-09-23 Chong Yidong <cyd@gnu.org>
4842 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4844 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4846 * .gdbinit: Just stop at fatal_error_backtrace.
4847 See Stefan Monnier's request in
4848 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4849 Remove no-longer-used query of system type.
4851 2012-09-22 Chong Yidong <cyd@gnu.org>
4853 * search.c (Freplace_match): Doc fix (Bug#12325).
4855 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4857 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4858 (Fline_end_position): Doc fix.
4860 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4862 2012-09-22 Chong Yidong <cyd@gnu.org>
4864 * dispextern.h (struct image_type): Add new slot, storing a type
4865 initialization function.
4867 * image.c (define_image_type): Call the image initializer function
4868 if it is defined. Arguments and return value changed.
4869 (valid_image_p, make_image): Callers changed.
4870 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4871 (gif_type, imagemagick_type, svg_type, gs_type):
4872 Add initialization functions.
4873 (Finit_image_library): Call lookup_image_type.
4874 (CHECK_LIB_AVAILABLE): Macro deleted.
4875 (lookup_image_type): Call define_image_type here, rather than via
4876 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4877 (syms_of_image): Move define_image_type calls for xbm_type and
4878 pbm_type to lookup_image_type.
4880 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4882 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4883 'idle_timers' from here ...
4884 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4885 lists, to avoid infloops when the timer does something stupid,
4886 like reinvoke itself with the same or smaller time-out.
4889 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4891 * window.c (Fsplit_window_internal): Handle only Qt value of
4892 Vwindow_combination_limit separately.
4893 (Qtemp_buffer_resize): New symbol.
4894 (Vwindow_combination_limit): New default value.
4897 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4899 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4900 the new overlay string. (Bug#10159)
4902 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4904 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4905 or that fprintf is async-signal-safe. POSIX doesn't require
4908 2012-09-22 Chong Yidong <cyd@gnu.org>
4910 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4913 2012-09-22 Kenichi Handa <handa@gnu.org>
4915 * composite.c (composition_reseat_it): Handle the case that a
4916 grapheme cluster is not covered by a single font (Bug#12352).
4918 2012-09-21 Chong Yidong <cyd@gnu.org>
4920 * image.c (define_image_type): Avoid adding duplicate types to
4921 image_types (Bug#12463). Suggested by Jörg Walter.
4923 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4925 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4926 (print_load_command_name): Add case LC_DATA_IN_CODE.
4927 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4929 2012-09-21 Glenn Morris <rgm@gnu.org>
4931 * eval.c (Frun_hook_with_args_until_success)
4932 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4934 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4936 * fileio.c (Ffile_selinux_context): Only call freecon when
4937 lgetfilecon succeeded.
4938 (Fset_file_selinux_context): Likewise. (Bug#12444)
4940 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4942 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4943 reordering, locate the cursor by calling set_cursor_from_row; if
4944 that fails, clear the desired glyph matrix before returning a
4945 failure indication to the caller. Fixes leaving garbled display
4946 when fast scrolling with a down-key. (Bug#12403)
4947 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4948 scrolling through multibyte text.
4950 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4952 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4953 calling mark_vectorlike since that's the one that marks the window.
4954 (mark_discard_killed_buffers): Mark the final cdr.
4955 * window.h (struct window): Move prev/next_buffers to the
4956 non-standard fields.
4957 * window.c (make_window): Initialize prev/next_buffers manually.
4959 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4961 Omit unused arg EXPECTED from socket hooks.
4962 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4963 * nsterm.m (ns_term_init):
4964 * termhooks.h (struct terminal.read_socket_hook):
4965 * w32inevt.c (w32_console_read_socket):
4966 * w32term.c (w32_read_socket):
4967 * xterm.c (XTread_socket):
4968 Omit unused arg EXPECTED. All callers changed.
4969 (store_user_signal_events): Return void, not int, since callers no
4970 longer care about the return value. All uses changed.
4972 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4974 * w32gui.h (XParseGeometry): Do not declare.
4976 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4978 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4979 Ignore 'expected'. See Eli Zaretskii in
4980 <http://bugs.gnu.org/12471#8> (last line).
4982 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4983 (XParseGeometry): Now static. Substitute extremal values for
4984 values that are out of range.
4986 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4988 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4990 * nsfns.m (XParseGeometry): Remove.
4991 (Fx_create_frame): Call x_set_offset to correctly interpret
4992 top_pos in geometry.
4994 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4995 (Fx_parse_geometry): If there is a space in string, call
4996 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4998 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5000 * search.c (scan_buffer): Use character positions in calls to
5001 region_cache_forward and region_cache_backward, not byte
5002 positions. (Bug#12196)
5004 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5005 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5007 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5008 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5009 emacs_blocked_malloc, now deleted.
5011 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5013 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5014 The workaround was for improving performance on Solaris 2.4, but
5015 is getting in the way now. Emacs will still work if someone is
5016 still running Solaris 2.4 in a museum somewhere; Sun dropped
5017 support for Solaris 2.4 in 2003.
5018 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5019 * process.c (create_process) [HAVE_WORKING_VFORK]:
5020 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5021 since Emacs no longer uses vfork on that platform.
5023 2012-09-17 Glenn Morris <rgm@gnu.org>
5025 * emacs.c: Use COPYRIGHT.
5027 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5029 Remove configure's --without-sync-input option (Bug#12450).
5030 When auditing signal-handling in preparation for cleaning it up,
5031 I found that SYNC_INPUT has race conditions and would be a real
5032 pain to fix. Since it's an undocumented and deprecated
5033 configure-time option, now seems like a good time to remove it.
5034 Also see <http://bugs.gnu.org/11080#16>.
5035 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5036 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5037 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5038 (malloc_hysteresis):
5039 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5040 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5041 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5042 (dont_register_blocks, bytes_used_when_reconsidered)
5043 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5044 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5045 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5046 Remove. All uses removed.
5047 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5048 implementation, one that depends on whether the new macro

5073 2012-09-16 Glenn Morris <rgm@gnu.org>

5077 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5079 (ns-app): Move here from ns.mk, and simplify.
5080 (clean): Simplify nextstep entry.
5081 * ns.mk: Remove file.
5083 2012-09-17 Kenichi Handa <handa@gnu.org>
5085 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5086 not covert the last few charactes.
5088 2012-09-16 Kenichi Handa <handa@gnu.org>
5090 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster

5104 explicit retain/release.

5110 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5111 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5112 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5113 the Microsoft problem in a different way, by altering ../nt/config.nt.
5115 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5130 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5131 by lisp.h. This completes removal of setjmp.h inclusion
5132 erroneously announced in the previous commit. (Bug#12446)
5134 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5137 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5138 not defined as a macro. The latter happens on MS-Windows.
5141 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5143 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5144 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5145 Some instances of '#include <setjmp.h>' removed, if the
5146 only reason for the instance was because "lisp.h" was included.
5147 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5148 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5149 and _longjmp with the new symbols. Emacs already uses _setjmp if
5150 available, so this change affects only POSIXish hosts that have
5151 sigsetjmp but not _setjmp, such as some versions of Solaris and
5152 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5153 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5154 (png_load_body) [HAVE_PNG]:
5155 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5156 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5157 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5158 since PNG requires jmp_buf. This is the only exception to the
5159 general rule that we now use sys_setjmp and sys_longjmp.
5160 This exception is OK since this code does not change the signal
5161 mask or longjmp out of a signal handler.
5163 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5165 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:

5170 Avoid out-of-range marker position (Bug#12426).
5171 * insdel.c (replace_range, replace_range_2):

5173 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5174 Remove redundant check before calling offset_intervals.
5176 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5178 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5179 current buffer (Bug#12387).
5181 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5183 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5185 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5187 Use a more backwards-compatible timer format (Bug#12430).
5188 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5189 vector element, not from the 4th, since PSECS is now at the end.
5190 (Fcurrent_idle_time): Doc fix.
5192 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5194 Function to mark objects and remove killed buffers at once.
5195 * alloc.c (discard_killed_buffers): Rename to ...
5196 (mark_discard_killed buffers) ... new name. Add marking
5197 of remaining objects. Fix comment. Adjust users.
5198 (mark_object): Do not touch frame buffer lists here.
5199 * frame.c (delete_frame): Reset frame buffer lists here.
5201 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5203 Better workaround for GNOME bug when --enable-gcc-warnings.
5204 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5205 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5206 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5208 Simplify SIGIO usage (Bug#12408).
5209 The code that dealt with SIGIO was crufty and confusing, e.g., it
5210 played tricks like "#undef SIGIO" but these tricks were not used
5211 consistently. Simplify mostly by not #undeffing standard symbols,
5212 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5213 or not as we please) rather than "defined SIGIO" (standard symbol
5214 that we probably shouldn't #undef).
5215 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5216 Modules that need it can include it.
5217 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5218 * dispextern.h (ignore_sigio): New decl.
5219 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5220 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5221 * emacs.c (shut_down_emacs):
5222 * keyboard.c (kbd_buffer_store_event_hold):
5223 Use ignore_sigio rather than invoking 'signal' directly.
5224 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5226 (FIONREAD, SIGIO): Do not #undef.
5227 (tty_read_avail_input): Use #error rather than a syntax error.
5228 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5229 for I_PIPE, used by SETUP_SLAVE_PTY.
5230 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5231 * sysdep.c (croak): Remove; no longer needed. This bit of
5232 temporary code, with Fred N. Fish's comment that it's temporary,
5233 has been in Emacs since at least 1992!
5234 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5235 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5236 * syssignal.h (croak): Remove decl.
5237 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5238 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5239 now that we're termios-only.
5240 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5241 * term.c (dissociate_if_controlling_tty): Use #error rather than
5244 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5245 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5246 to work around GNOME bug 683906.
5247 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5248 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5249 This works around GCC bug 54561.
5251 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5253 More fixes for 'volatile' and setjmp/longjmp.
5254 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5255 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5256 (png_load_body) [HAVE_PNG]:
5257 (jpeg_load_body) [HAVE_JPEG]:
5258 New function, with most of the old parent function's body.
5259 (png_load) [HAVE_PNG]:
5260 (jpeg_load) [HAVE_JPEG]:
5261 Invoke the new function, to avoid longjmp munging our locals.
5262 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5263 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5264 longjmp is passed 2, as the C standard doesn't guarantee this.
5265 Instead, store the failure code into mgr->failure_code.
5267 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5269 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5270 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5271 (syms_of_keyboard): Remove support for unread-command-char.
5273 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5275 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5276 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5277 violation. (Bug#12426)
5279 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5281 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5283 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5285 * eval.c: Add `inhibit-debugger'.
5286 (Qinhibit_debugger): New symbol.
5287 (call_debugger): Bind it instead of Qdebug_on_error.
5288 (maybe_call_debugger): Test Vinhibit_debugger.
5289 (syms_of_eval): Define inhibit-debugger.
5290 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5291 (syms_of_xdisp): Remove inhibit-debug-on-message.
5293 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5295 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5296 If a nonvolatile local variable is written before a _longjmp to
5297 the frame containing the variable, and is read after the _longjmp,
5298 the value read is indeterminate. Some local variables of type
5299 'struct handler' and 'struct catchtag' are used in this way, so
5300 mark each of their slots as volatile if the slot can be set before
5301 _longjmp and read afterwards.
5302 * lisp.h (struct handler): var and chosen_clause are now volatile.
5303 (struct catchtag): val, next, and pdlcount are now volatile.
5305 * bidi.c (bidi_push_it, bidi_pop_it):
5306 * fns.c (copy_hash_table):
5307 * image.c (define_image_type):
5308 * keyboard.c (kbd_buffer_store_event_hold):
5309 * process.c (Fprocess_send_eof):
5310 * xfaces.c (x_create_gc) [HAVE_NS]:
5311 * xgselect.c (xg_select):
5312 Prefer assignment to memcpy when either will do.
5314 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5315 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5316 time an item is removed. No need to mark this function 'inline';
5317 the compiler knows better than we do.
5319 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5321 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5322 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5323 to change_frame_size (Bug#12388).
5324 (windowDidResize:): Pass YES to updateFrameSize.
5326 * nsterm.h: Add delay parameter to updateFrameSize.
5328 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5330 Discard killed buffers from deleted window and frame objects.
5331 This reduces an amount of references to killed buffers and
5332 helps GC to reclaim them faster.
5333 * alloc.c (discard_killed_buffers): New function.
5334 (mark_object): Use it for deleted windows and frames.
5335 (mark_object): If symbol's value is set up for a killed buffer
5336 or deleted frame, restore its global binding.
5337 * data.c (swap_in_global_binding): Add GC notice.
5338 (swap_in_symval_forwarding): Use convenient set_blv_where.
5339 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5340 * window.h: ... to here.
5342 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5344 Convenient macro to check whether the buffer is live.
5345 * buffer.h (BUFFER_LIVE_P): New macro.
5346 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5347 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5349 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5351 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5352 composition cases (Bug#12364).
5354 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5355 overhang of succeeding glyphs overlapping box cursor.
5357 * w32term.c (x_draw_glyph_string): Likewise.
5359 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5361 Simplify, document, and port floating-point (Bug#12381).
5362 The porting part of this patch fixes bugs on non-IEEE platforms
5363 with frexp, ldexp, logb.
5364 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5366 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5367 support, by removing commented-out code and briefly listing the
5368 C89 functions excluded. The commented-out stuff was confusing
5369 maintenance, e.g., we thought we needed cbrt but it was commented out.
5370 (logb): Remove decl; no longer needed.
5371 (isfinite): New macro, if not already supplied.
5372 (isnan): Don't replace any existing macro.
5373 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5374 are present on all C89 platforms.
5375 (Ffrexp): Do not special-case zero, as frexp does the right thing
5377 (Flogb): Do not use logb, as it doesn't have the desired meaning
5378 on hosts that use non-base-2 floating point. Instead, stick with
5379 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5380 frexp, to avoid getting an unspecified result.
5382 * xdisp.c (Qinhibit_debug_on_message): Now static.
5384 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5386 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5387 NSBezierPath (Bug#12131).
5389 2012-09-10 Chong Yidong <cyd@gnu.org>
5391 * fns.c (Fdelq, Fdelete): Doc fix.
5393 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5395 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5396 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5398 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5400 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5401 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5404 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5406 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5407 left fringe if the window has a left margin. This avoids leaving
5408 traces of the cursor because its leftmost pixel is not drawn over.
5410 * dispnew.c (update_window_line): When the left margin area of a
5411 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5412 that screen line. (Bug#12277)
5414 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5416 Assume C89 or later for math functions (Bug#12381).
5417 This simplifies the code, and makes it a bit smaller and faster,
5418 and (most important) makes it easier to clean up signal handling
5419 since we can stop worring about floating-point exceptions in
5420 library code. That was a problem before C89, but the problem
5421 went away many years ago on all practical Emacs targets.
5422 * data.c, image.c, lread.c, print.c:
5423 Don't include <math.h>; no longer needed.
5424 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5425 might be autoconfigured, as that never happens.
5427 * doprnt.c (DBL_MAX_10_EXP):
5428 * print.c (DBL_DIG):
5429 Remove. C89 or later always defines these.
5430 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5431 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5432 (arith_error, domain_error, domain_error2):
5433 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5434 no longer needed -- we simply return what C returns. All uses removed.
5435 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5437 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5438 Remove. All uses expanded, as these macros are no longer used
5439 more than once and are now more trouble than they're worth.
5440 (Ftan): Use tan, not sin / cos.
5441 (Flogb): Assume C89 frexp.
5442 (fmod_float): Assume C89 fmod.
5443 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5444 (init_floatfns): Remove. All uses removed.
5446 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5448 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5449 compositeToPoint for OSX < 10.6 (Bug#12390).
5451 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5453 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5454 This produces more-accurate results.
5456 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5458 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5459 changes (Bug#12088).
5461 2012-09-08 Chong Yidong <cyd@gnu.org>
5463 * syntax.c (Fstring_to_syntax): Doc fix.
5465 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5467 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5468 in the internal border.
5469 (x_set_window_size): Remove static variables and their usage.
5470 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5471 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5472 Remove fringe/internal border adjustment (Bug#11052).
5473 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5474 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5475 (ns_fix_rect_ibw): Remove.
5476 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5477 (ns_dumpglyphs_box_or_relief): Ditto.
5478 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5480 (ns_dumpglyphs_image): Ditto.
5481 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5483 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5484 their usage. Add fringe_extended_p and its use as in other terms.
5485 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5486 scroll bar was removed.
5487 (updateFrameSize): New function.
5488 (windowDidResize): Move code to updateFrameSize and call it.
5490 * nsterm.h (EmacsView): Add updateFrameSize.
5492 2012-09-07 Chong Yidong <cyd@gnu.org>
5494 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5496 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5498 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5500 More signal-handler cleanup (Bug#12327).
5501 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5502 Problem introduced when merging patches. Noted by Eli Zaretskii in
5503 <http://bugs.gnu.org/12327#67>.
5504 * floatfns.c: Comment fix.
5505 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5506 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5507 and anyway the declaration is harmless even if SIGDANGER is not defined.
5508 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5509 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5510 source files not surprisingly expected syssignal.h to define, or
5511 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5512 Include <sys/ioctl.h>, for FIONREAD.
5513 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5514 This eliminates a problem whereby other files mysteriously had
5515 to include "syssignal.h" before including "systty.h" if they
5516 wanted to use "#ifdef SIGIO".
5518 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5520 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5522 * w32.c (sigemptyset): Empty the set.
5523 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5525 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5527 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5529 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5530 (mark_object): Likewise for frame objects.
5532 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5534 * syssignal.h (handle_on_main_thread): Always declare,
5535 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5536 This ports to platforms without HAVE_PTHREAD.
5538 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5540 Signal-handler cleanup (Bug#12327).
5541 Emacs's signal handlers were written in the old 4.2BSD style with
5542 sigblock and sigmask and so forth, and this led to some
5543 inefficiencies and confusion. Rewrite these to use
5544 pthread_sigmask etc. without copying signal sets around. Also,
5545 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5546 'signal', and instead use functions that do not attempt to take
5547 over the system name space. This patch causes Emacs's text
5548 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5549 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5550 Do not include <signal.h> or "syssignal.h", as these
5551 modules do not use signals.
5552 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5553 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5554 Do not include <signal.h>, as "syssignal.h" does that for us now.
5555 * atimer.c (sigmask_atimers): New function.
5556 (block_atimers, unblock_atimers): New functions,
5557 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5559 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5560 no longer needed here.
5561 * emacs.c (main): Inspect existing signal handler with sigaction,
5562 so that there's no need to block and unblock SIGHUP.
5563 * sysdep.c (struct save_signal): New member 'action', replacing
5564 old member 'handler'.
5565 (save_signal_handlers, restore_signal_handlers):
5566 Use sigaction instead of 'signal' to save and restore.
5567 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5568 New function. All users of 'signal' modified to use set_sighandler
5569 if they're writeonly, and to use sys_signal if they're read+write.
5570 (emacs_sigaction_init, forwarded_signal): New functions.
5571 (sys_signal): Remove. All uses replaced by calls to sigaction
5572 and emacs_sigaction_init, or by direct calls to 'signal'.
5573 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5574 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5575 all uses replaced by pthread_sigmask etc. calls.
5576 * syssignal.h: Include <signal.h>.
5577 (emacs_sigaction_init, forwarded_signal): New decls.
5578 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5579 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5580 (sigmask, sys_sigmask): Remove; no longer needed.
5581 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5582 (sigblock, sigunblock, sigfree):
5583 (sigsetmask) [!defined sigsetmask]:
5584 Remove. All uses replaced by pthread_sigmask.
5585 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5586 no longer need to be replaced, and its typical old uses
5587 are now done via emacs_sigaction_init and sigaction.
5588 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5589 (sys_sigdel): Remove; unused.
5590 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5592 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5594 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5595 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5597 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5599 Explicitly mark buffer_defaults and buffer_local_symbols.
5600 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5601 mark_local_symbols here.
5602 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5603 since special buffers aren't marked here any more.
5604 (allocate_buffer): Chain new buffer with all_buffers here...
5605 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5607 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5608 (syms_of_buffer): Remove staticpro of the above.
5609 (init_buffer_once): Set names for buffer_defaults and
5610 buffer_local_symbols.
5612 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5614 Use bool for booleans in font-related modules.
5615 * font.c (font_intern_prop, font_style_to_value)
5616 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5617 (generate_otf_features, font_check_otf_features, font_check_otf)
5618 (font_match_p, font_list_entities, font_at):
5619 * fontset.c (fontset_id_valid_p, reorder_font_vector
5620 (fontset_find_font, Fset_fontset_font)
5621 (face_suitable_for_char_p) [0]:
5622 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5623 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5624 (m17n_flt_initialized, ftfont_shape_by_flt):
5625 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5626 * nsfont.m (nsfont_draw):
5627 * w32font.c (w32font_draw):
5628 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5629 Use bool for booleans.
5630 * font.h: Adjust to above API changes.
5631 (struct font, struct font_driver, struct font_driver_list):
5632 Use bool for booleans.
5633 (struct font): Remove useless member encoding_type.
5635 * fontset.c, xftfont.c: Omit unnecessary static decls.
5637 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5639 * alloc.c (mark_object): Revert window marking code
5640 since it's unsafe for the Fset_window_configuration.
5642 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5644 Fix race conditions with signal handlers and errno (Bug#12327).
5645 Be more systematic about preserving errno whenever a signal
5646 handler returns, even if it's not in the main thread. Do this by
5647 renaming signal handlers to distinguish between signal delivery
5648 and signal handling. All uses changed.
5649 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5650 * data.c (deliver_arith_signal): Rename from arith_error.
5651 * dispnew.c (deliver_window_change_signal): Rename from
5652 window_change_signal.
5653 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5654 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5655 * keyboard.c (deliver_input_available_signal): Rename from
5656 input_available_signal.
5657 (deliver_user_signal): Rename from handle_user_signal.
5658 (deliver_interrupt_signal): Rename from interrupt_signal.
5659 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5660 (deliver_child_signal): Rename from sigchld_handler.
5661 * atimer.c (handle_alarm_signal):
5662 * data.c (handle_arith_signal):
5663 * dispnew.c (handle_window_change_signal):
5664 * emacs.c (handle_fatal_signal, handle_danger_signal):
5665 * keyboard.c (handle_input_available_signal):
5666 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5667 * process.c (handle_pipe_signal, handle_child_signal):
5668 New functions, with the actual signal-handling code taken from the
5669 original respective signal handlers, sans the sporadic attempts to
5670 preserve errno, since that's now done by handle_on_main_thread.
5671 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5672 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5673 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5675 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5676 Move initialization of main_thread to sysdep.c's init_signals.
5677 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5678 our usage, and simplifies the mainline code.
5679 (record_child_status_change): New static function, as a helper
5680 for handle_child_signal, and with most of the old child handler's
5682 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5683 (handle_child_signal): Use the above.
5684 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5685 Moved here from emacs.c.
5686 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5687 code moved here from emacs.c's main function.
5688 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5689 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5690 This lets callers save and restore errno properly.
5692 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5694 Remove redundant or unused things here and there.
5695 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5696 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5697 * editfns.c (Fcompare_buffer_substrings): Likewise.
5698 * frame.h (struct terminal, struct font_driver_list):
5699 Remove redundant declarations.
5700 * window.h (Qleft, Qright): Likewise.
5702 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5704 Do not mark objects from deleted buffers, windows and frames.
5705 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5706 (mark_object): Likewise for windows and frames.
5708 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5710 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5711 buffer_defaults and buffer_local_symbols as valid objects.
5712 Return special value to denote them.
5714 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5716 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5717 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5718 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5719 (file_name_absolute_p, Fsubstitute_in_file_name):
5720 (check_executable, check_writable, Ffile_accessible_directory_p)
5721 (Fset_file_selinux_context, Fdefault_file_modes)
5722 (Finsert_file_contents, choose_write_coding_system)
5723 (Fwrite_region, build_annotations, a_write, e_write)
5725 * filelock.c (boot_time_initialized, get_boot_time)
5726 (get_boot_time_1, lock_file_1, within_one_second):
5727 * floatfns.c (in_float):
5728 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5729 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5730 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5731 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5732 * window.c (compare_window_configurations):
5733 Use bool for booleans.
5734 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5735 (Fdefault_file_modes): Now mode_t, not int, for modes.
5736 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5737 (internal_delete_file): Now returns void, not a (boolean) int,
5738 since nobody was looking at the return value.
5739 * lisp.h, window.h: Adjust to above API changes.
5741 * xdisp.c (set_message): Simplify and reindent last change.
5743 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5745 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5747 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5749 * eval.c (call_debugger): Make the function non-static so that we
5750 can call it from set_message.
5752 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5753 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5755 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5757 Give more-useful info on a fatal error (Bug#12328).
5758 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5759 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5760 of doing the work ourselves.
5761 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5762 do most of the work.
5763 (fatal_error_backtrace): New function, taken from the guts
5764 of the old fatal_error_signal, but with a new option to output
5766 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5767 info about the signal than just its number.
5768 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5769 * sysdep.c: Include <execinfo.h>
5770 (emacs_backtrace): New function, taken partly from the previous
5771 code of the 'die' function.
5772 (emacs_abort): Call fatal_error_backtrace rather than abort.
5774 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5776 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5777 eager (load-time) macro-expansion.
5778 * lisp.mk (lisp): Add macroexp.
5780 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5782 Simplify redefinition of 'abort' (Bug#12316).
5783 Do not try to redefine the 'abort' function. Instead, redo
5784 the code so that it calls 'emacs_abort' rather than 'abort'.
5785 This removes the need for the NO_ABORT configure-time macro
5786 and makes it easier to change the abort code to do a backtrace.
5787 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5788 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5789 Remove; sysdep.c's emacs_abort now takes its place.
5790 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5791 'abort' changed to use 'emacs_abort'.
5792 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5793 (abort) [!defined abort]: Rename to ...
5794 (emacs_abort): ... new name.
5795 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5796 the place of the old 'abort' in emacs.c.
5797 * w32.c, w32fns.c (abort): Do not #undef.
5798 * w32.c (emacs_abort): Rename from w32_abort.
5800 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5802 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5803 offsets[j].dv, since the y axis of the screen coordinates points
5804 down, while the y axis of the font definition coordinates points
5805 up. This fixes display of Arabic diacritics such as KASRA and
5806 KASRATAN. (Bug#11860)
5808 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5810 Be more systematic about _setjmp vs setjmp.
5811 * alloc.c (test_setjmp, mark_stack):
5812 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5813 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5814 (png_load, my_error_exit, jpeg_load):
5815 * process.c (send_process_trap, send_process):
5816 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5817 The underscored versions are up to 30x faster on some hosts.
5818 Formerly, the code used setjmp+longjmp sometimes and
5819 _setjmp+_longjmp at other times, with no particular reason to
5820 prefer setjmp+longjmp.
5822 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5824 Fix minor problem found by static checking.
5825 * buffer.c (Fdelete_all_overlays): Return nil.
5827 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5829 * buffer.c (Fdelete_all_overlays): New function.
5831 2012-09-03 Chong Yidong <cyd@gnu.org>
5833 * gtkutil.c: Add extern decl for Qxft.
5835 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5837 * emacs.c, eval.c: Use bool for boolean.
5838 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5839 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5840 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5841 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5842 (main, decode_env_path, Fdaemon_initialized):
5843 * eval.c (call_debugger, Finteractive_p, interactive_p):
5844 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5845 (maybe_call_debugger, Fbacktrace):
5846 * process.c (read_process_output, exec_sentinel):
5847 Use bool for booleans.
5848 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5849 All callers changed.
5850 * eval.c (interactive_p): Omit always-true boolean argument
5851 EXCLUDE_SUBRS_P. All callers changed.
5852 * dispextern.h, lisp.h: Reflect above API changes.
5853 * firstfile.c (dummy): Use the address of 'main', whose signature
5854 won't change, instead of the address of 'initialize', whose
5855 signature just changed from int to bool.
5856 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5857 * msdos.c (fatal_error_in_progress): ... from here.
5858 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5860 (redisplay_internal, unwind_redisplay): Simply clear
5861 REDISPLAYING_P when unwinding, instead of saving its previous,
5862 always-false value and then restoring it.
5864 Clean up some extern decls.
5865 Mostly, this hoists extern decls out of .c files and into .h files.
5866 That way, we're more likely to catch errors if the interfaces change.
5867 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5868 declare xg_mark_data.
5869 * dispextern.h (x_frame_parm_handlers):
5871 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5872 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5873 (Qultra_bold, Qoblique, Qitalic):
5874 Move extern decl here from .c file.
5875 * alloc.c (xg_mark_data) [USE_GTK]:
5877 * eval.c (Qlexical_binding):
5878 * fns.c (time) [!HAVE_UNISTD_H]:
5879 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
5880 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

5882 * lread.c (Qinternal_interpreter_environment):
5883 * minibuf.c (Qbuffer):
5884 * process.c (QCfamily, QCfilter):
5885 * widget.c (free_frame_faces):
5886 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5887 * xfont.c (x_clear_errors):
5888 * xterm.c (x_frame_parm_handlers):
5889 Remove now-redundant extern decls.
5890 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5891 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5893 * xfaces.c: Remove unnecessary static decls.
5894 * xterm.c (updating_frame): Remove decl of nonexistent object.
5896 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5897 when building globals.h, as the objects that are not built on
5898 this host are not needed to compile C files on this host.
5900 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5902 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5904 * frame.h: Add missing prototype for x_wm_set_size_hint.
5906 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5908 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

5910 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5911 (Fsubstitute_command_keys):

5916 (make_buffer_string, make_buffer_string_both)
5917 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5954 offset adjustment values separately for each cluster. (Bug#11860)
5956 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5957 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5958 about implicit conversions from integer to pointer.

6016 window system declarations.
6018 * frame.h: Move common functions here: set_frame_menubar,
6019 x_set_window_size, x_sync, x_get_focus_frame,
6020 x_set_mouse_position, x_set_mouse_pixel_position,
6021 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6077 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6078 for GCC 4.7.1 x86-64.
6080 2012-08-30 Glenn Morris <rgm@gnu.org>
6082 * lread.c (init_lread): For out-of-tree builds, only add the
6083 source directory's site-lisp dir to the load-path if it exists,
6084 consistent with in-tree builds. (Bug#12302)
6086 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6320 It was meant to be temporary and it often doesn't work,
6321 because when IDX has side effects the behavior of IDX==IDX
6322 is undefined. See Stefan Monnier in
6323 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

6339 All uses and decls removed.

6370 * lisp.h, process.h: Adjust prototypes to match above changes.
6371 * callint.c (Fcall_interactively): Don't assume the mark's
6372 offset fits in 'int'.

6383 (mmap_enlarge, mmap_set_vars):
6384 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6385 Use bool for booleans, instead of int.
6386 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6387 since the 1-or-0 return value is always ignored anyway.
6388 (mmap_initialized_p):
6389 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6390 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6392 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6394 * bidi.c: Use bool for boolean.
6395 This is a bit more readable, and makes the text segment of bidi.o
6396 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6397 Presumably it's faster too.

6407 (bidi_unshelve_cache): Adjust decls to match code.
6409 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6411 * keyboard.c (Fposn_at_x_y): Do not allow internal window as

6416 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6417 * atimer.h: Include <stdbool.h>.
6419 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6421 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6422 compile time tests instead of run time tests on systems that do
6424 (FRAME_MAC_P): Remove leftover from deleted code.
6425 * frame.c (syms_of_frame): Remove leftover from deleted code.
6427 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6431 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6433 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6434 Otherwise, the compiler complains about (A?B:C) where B is void
6435 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6436 (fontset_add): Return void, for FONTSET_ADD.
6438 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

6451 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6452 Remove unused local.
6453 * alloc.c (PURE_POINTER_P):
6454 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.

6461 * lread.c (readchar, read1):
6462 * print.c (Fprin1_to_string):
6463 * xdisp.c (push_message):
6464 Use bool for booleans affected directly or indirectly by
6467 Make recently-introduced setters macros.
6468 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6469 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6470 (set_fontset_default, set_fontset_fallback): Rename from their
6471 upper-case counterparts, and make them functions rather than macros.
6472 This is more consistent with the other recently-introduced setters.
6473 These don't need to be inline, since they're local.
6475 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6477 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6478 the loop (Bug#12247).
6480 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6482 * lisp.h (vcopy): Use memcpy rather than our own loop.
6483 This fixes a performance regression introduced by the recent
6484 addition of vcopy. This means 'vcopy' will need to be modified
6485 for a copying collector, but that's OK. Also, tighten the
6486 checking in the assertion.
6488 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6490 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6491 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6492 non-base glyph for the width of the base character, according to
6493 what x_draw_composite_glyph_string_foreground expects.
6494 Generate WADJUST value according to composition_gstring_width's
6495 expectations, to produce correct width of the composed character.
6496 Reverse the sign of the DU offset produced by ScriptPlace.
6498 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6500 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6502 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6504 Avoid direct writes to contents member of struct Lisp_Vector.
6505 * lisp.h (vcopy): New function to copy data into vector.
6506 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6507 * fns.c (Ffillarray): Use ASET.
6508 * keyboard.c (timer_check_2): Use AREF and ASET.
6509 (append_tool_bar_item, Frecent_keys): Use vcopy.
6510 * lread.c (read_vector): Use ASET.
6511 * msdos.c (Frecent_doskeys): Use vcopy.
6512 * xface.c (Finternal_copy_lisp_face): Use vcopy.

6519 the position of its buffer's point.
6520 (Fset_window_point): For the selected window always go in its
6521 buffer to the specified position.
6523 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6525 Setter macros for fontsets.
6526 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6527 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6528 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6531 2012-08-20 Glenn Morris <rgm@gnu.org>
6533 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6534 Don't assume that `ln -f' works.
6536 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6538 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6539 and later about non-assignments with no effect. See discussion at
6540 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for

6549 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6551 * window.c (select_window): Always make selected window's buffer
6554 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6556 Use AREF and ASET for docstrings of category tables.
6557 * category.h (CATEGORY_DOCSTRING): Use AREF.
6558 (SET_CATEGORY_DOCSTRING): Use ASET.
6559 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6561 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6563 Inline setter functions for hash table members.
6564 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6565 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6566 (set_hash_key_and_value, set_hash_index, set_hash_next)
6567 (set_hash_hash): New functions.
6568 * charset.c, fns.c: Adjust users.
6570 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6572 Inline getter and setter functions for per-buffer values.
6573 * buffer.h (per_buffer_default, set_per_buffer_default)
6574 (per_buffer_value, set_per_buffer_value): New functions.
6575 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6576 * buffer.c, data.c: Adjust users.
6578 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6580 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6582 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6584 Rely on <config.h> + <unistd.h> to declare 'environ',
6585 as gnulib does this if the system doesn't.
6586 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6587 Remove declaration. MS-Windows declares it on stdlib.h which is
6588 included by conf_post.h.
6589 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6590 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6591 * vm-limit.c: Include <unistd.h>, for 'environ'.
6593 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6594 (start_of_data): Remove decl; mem-limits.h provides it.
6596 * xdisp.c (handle_invisible_prop): Make it a bit faster
6597 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6599 2012-08-19 Chong Yidong <cyd@gnu.org>
6601 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6604 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6606 * .gdbinit: Use call instead of set when calling a function in the
6609 * data.c (set_internal): Don't use set_blv_found.
6610 (Fkill_local_variable): Likewise.
6612 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6614 * nsfont.m (ns_ascii_average_width): Ensure the string
6615 ascii_printable is initialized with a null-terminated character
6616 array. Otherwise, it can contain undesired extra characters.
6618 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6620 port new setting code to Sun C 5.8 2005/10/13
6621 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6622 Return void, not Lisp_Object. Otherwise, the compiler
6623 complains about (A?B:C) where B is void and C is Lisp_Object
6624 when compiling CHAR_TABLE_SET, due to the recent change to
6625 the API of sub_char_table_set_contents.
6627 2012-08-18 Chong Yidong <cyd@gnu.org>
6629 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6630 for the string case (Bug#3874).

6751 A few more naming-convention fixes for getters and setters.
6752 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,
6753 and rename from buffer_overlays_set_before.
6754 (set_buffer_overlays_after): Move here from buffer.h, and rename
6755 from buffer_overlays_set_after.
6756 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

6763 (set_interval_right): Move here from intervals.h, and rename from
6765 (copy_interval_parent): Move here from intervals.h, and rename from
6766 interval_copy_parent.
6767 * intervals.h (set_interval_parent): Rename from interval_set_parent.
6768 (set_interval_plist): Rename from interval_set_plist.
6769 Return void, not Lisp_Object, since no caller uses the result.

6783 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
6784 "set_char_table_parent (char_table, parent);".
6785 The old version was confusing because it used the same name
6786 'parent' for two different things.
6788 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6790 Functions to get and set Lisp_Object fields of buffer-local variables.

6793 (BLV_FOUND, SET_BLV_FOUND, BLV_VALUE, SET_BLV_VALUE): Remove.
6794 * data.c, eval.c, frame.c: Adjust users.
6796 2012-08-17 Chong Yidong <cyd@gnu.org>
6798 * xfaces.c (merge_face_vectors): If the target font specfies a

7457 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7458 * w32.c (init_environment): Change the default values of many
7459 environment variables in dflt_envvars[] to NULL, to avoid pushing
7460 them into environment when they were not already defined.
7461 Remove the code that deletes site-lisp subdirectories from the default
7462 value of EMACSLOADPATH, as it is no longer needed.
7463 (check_windows_init_file): Now external, not static.
7464 Use Vload_path as is, without adding anything, as this function is now
7465 called when Vload_path is already set up.
7467 * w32.h (check_windows_init_file): Add prototype.
7469 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7471 compatibility with Posix platforms.
7472 (main): Move the call to check_windows_init_file to here from

7475 any, in the DEFALT argument into the root of the Emacs build or
7476 installation tree, as appropriate.
7478 * callproc.c (init_callproc_1): Call decode_env_path instead of
7479 doing its equivalent by hand.
7480 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
7481 the code that sets Vexec_path run on MS-Windows.
7483 * lread.c (init_lread): Add comments to #ifdef's.
7485 * msdos.c (dos_set_window_size, IT_update_begin)

7497 Remove unnecessary casts involving pointers.
7498 These casts are no longer needed now that we assume C89 or later,

7512 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7513 Remove unnecessary pointer casts.
7514 * alloc.c (record_xmalloc): New function.
7515 * lisp.h (record_xmalloc): New decl.
7516 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7517 more like a function. This is because the pointer cast is not
7518 needed. All uses changed.
7519 * print.c (print_string, print_error_message): Avoid length recalc.
7521 Improve fix for macroexp crash with debugging (Bug#12118).
7522 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7523 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7524 not supposed to be invoked from the garbage collector.
7525 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7526 (gc_aset): New function, which is like ASET but can be
7527 used in the garbage collector.
7528 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7543 headers (most versions of MinGW w32api don't).
7544 (get_security_info, create_symbolic_link)
7545 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7547 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7548 in the argument file name.

7552 have the required privileges.
7553 (get_file_security_desc_by_name): Rename from
7554 get_file_security_desc.
7555 (stat_worker): New function, with most of the guts of 'stat', and
7556 with addition of handling of symlinks and support for 'lstat'.
7557 If possible, get file's attributes and security information by
7558 handle, not by name. Produce S_IFLNK bit for symlinks, when
7559 called from 'lstat'.
7560 (stat, lstat): New functions, call 'stat_worker'.
7561 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7562 symlinks when the underlying filesystem supports them.
7564 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7566 Fix macroexp crash on Windows with debugging (Bug#12118).
7567 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7568 checking subscripts; problem introduced with the recent
7569 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7570 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7571 since it's used in non-static inline functions now.
7573 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7574 Don't assume buffer size fits in 'int'. Remove unused local.

7591 * category.c (CATEGORY_INLINE):
7592 * character.c (CHARACTER_INLINE):
7593 * charset.c (CHARSET_INLINE):
7594 * composite.c (COMPOSITE_INLINE):
7595 * dispnew.c (DISPEXTERN_INLINE):
7596 * sysdep.c (SYSTIME_INLINE):
7597 Define to EXTERN_INLINE, so that the corresponding functions
7598 are compiled into code.
7599 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7600 (INLINE_HEADER_END): New macros.
7601 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7621 hard-coding the path separator.
7623 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7625 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7626 This how ASET and AREF are supposed to work, and makes
7627 it easier to think about future improvements. See
7628 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7629 * charset.h (set_charset_attr): New function.

8121 the fix for 12036 would have avoided some of the problems noted in

8144 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8145 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8146 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8147 Adjust to changes in lisp.h and emacs.c, by using
8148 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8149 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8150 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8151 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8152 instead of gdb_valbits.
8153 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8154 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8155 instead of gdb_array_mark_flag.
8156 (xboolvector): Get size from $->size, not $->header.size.
8157 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8158 (xreload, hook-run, hookpost-run): Remove.
8159 * emacs.c: Include <verify.h>.
8160 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

8167 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8168 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8169 as constants, so they're visible to GDB.

8171 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8172 Now enum constants, not macros, so they're visible to GDB.
8173 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8174 more convenient now. All uses changed.
8175 (VALMASK) [USE_LSB_TAG]: Also define in this case.

8191 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8192 than macros. This simplifies debugging in the usual case, since
8193 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8194 and it allows expressions involving EMACS_INT casts.
8195 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8197 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8214 buffer_defaults and buffer_local_symbols (for sanity and safety).
8216 2012-07-24 Eli Zaretskii <eliz@gnu.org>

8249 Swap buffer text indirection counters in Fbuffer_swap_text.
8250 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8251 This avoids crash reported by Christoph Scholtes at
8252 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8254 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8256 * nsmenu.m (Popdown_data): New struct.

8281 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8282 as it's limited by the amount of memory, not by INT_MAX.
8284 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8286 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

9060 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9061 * nsterm.m (ns_term_init):
9062 Avoid the need for strncpy, by using build_string or
9063 make_unibyte_string directly. Use dtoastr, not snprintf.
9064 * process.c (Fmake_network_process): Diagnose service names that
9065 are too long, rather than silently truncating them or creating
9066 non-null-terminated names.
9067 (Fnetwork_interface_info): Likewise, for interface names.
9068 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9069 Prefer sprintf to strncat.
9070 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

9082 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9083 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9084 where argument type is known to be a Lisp_Cons.

9096 Optimize pure C strings initialization.
9097 * lisp.h (make_pure_string): Fix prototype.
9098 (build_pure_c_string): New function, defined as static inline. This
9099 provides a better opportunity to optimize away calls to strlen when
9100 the function is called with compile-time constant argument.
9101 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9102 argument, adjust users accordingly. Use build_pure_c_string where
9104 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9105 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9106 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9108 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9110 Avoid calls to strlen in miscellaneous functions.
9111 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9112 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9113 * lread.c (openp): Likewise.
9115 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9117 Avoid calls to strlen in path processing functions.
9118 * fileio.c (file_name_as_directory): Add comment. Change to add
9119 srclen argument and return the length of result. Adjust users

9123 Adjust users accordingly.
9124 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9126 2012-07-10 Glenn Morris <rgm@gnu.org>
9128 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9133 * s/gnu.h (DATA_START): Move definitions to configure.
9135 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9136 We include usg5-4-common.h, which defines them both.
9138 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9139 O_RDONLY already includes it).
9141 Stop ns builds setting the EMACSLOADPATH environment variable.
9142 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9143 Now it does not set EMACSLOADPATH, just returns the load-path string.
9144 * nsterm.h: Update accordingly.
9145 * lread.c [HAVE_NS]: Include nsterm.h.
9146 (init_lread) [HAVE_NS]: Use ns_load_path.

9149 2012-07-09 Glenn Morris <rgm@gnu.org>
9151 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9152 since the included bsd-common.h does so.
9154 Stop ns builds setting the EMACSPATH environment variable.
9155 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9156 (ns_init_paths): Do not set EMACSPATH.
9157 * nsterm.h (ns_exec_path): Add it.
9158 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9161 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9163 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9165 * process.c (wait_reading_process_output): 'waitchannels' was unset
9166 when read_kbd || !NILP (wait_for_cell); fix this.
9168 Add GCC-style 'const' attribute to functions that can use it.
9169 * character.h (char_resolve_modifier_mask):
9170 * keyboard.h (make_ctrl_char):
9171 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9180 Add decls with ATTRIBUTE_CONST.
9182 Minor improvements to make_formatted_string.
9183 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9184 where int is good enough, as vsprintf returns an int.
9185 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9187 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9189 Use make_formatted_string to avoid double length calculation.
9190 * lisp.h (make_formatted_string): New prototype.
9191 * alloc.c (make_formatted_string): New function.
9192 * buffer.c (Fgenerate_new_buffer_name): Use it.

9214 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9216 Move marker debugging code under MARKER_DEBUG.
9217 * marker.c (MARKER_DEBUG): Move marker debugging code under
9218 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9219 for bootstrap with --enable-checking (~3x slowdown reported
9220 by Juanma Barranquero <lekktu@gmail.com>).
9221 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9223 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9225 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9226 See <http://bugs.gnu.org/11825#29>.
9228 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9230 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9231 has no font, use the frame's font. (Bug#11813)
9232 (display_line): Add commentary about displaying truncation glyphs
9234 (produce_special_glyphs): Move here from term.c.
9236 * term.c (produce_special_glyphs): Move to xdisp.c.
9238 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9241 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9243 * xdisp.c (display_line): Avoid warning about implicit declaration
9246 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9248 * lisp.h: Remove empty conditional.
9250 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9252 * lread.c (load_path_check): Now static.
9254 Fix some minor --with-ns problems found by static checking.
9255 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9256 (x_set_font) [!HAVE_X_WINDOWS]:
9257 * image.c (xpm_load_image) [HAVE_NS]:
9258 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9259 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9260 Remove unused local.
9261 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9262 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9263 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9264 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9265 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9266 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9267 Fix pointer signedness problem.
9268 * xfaces.c (FRAME_X_FONT_TABLE):
9269 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9271 2012-07-07 Glenn Morris <rgm@gnu.org>
9273 * lread.c (load_path_check): New function, split from init_lread.
9274 (init_lread): Reorganize. Motivation:
9275 If EMACSLOADPATH is set, check/warn about that rather than the
9276 defaults, which we are not going to use. Hence we can remove
9277 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9278 Don't warn if site-lisp directories are missing.
9279 If not installed, start from a blank load-path, since
9280 PATH_LOADSEARCH refers to the eventual installation directories.
9282 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9284 Support truncation and continuation glyphs on GUI frames, when
9285 fringes are disabled. (Bug#11832)
9286 * xdisp.c (init_iterator): Get dimensions of truncation and
9287 continuation glyphs even if on GUI frames.
9288 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9289 or both, are absent.
9290 (start_display, move_it_in_display_line_to): Handle the case of a
9291 GUI frame without a fringe to display continuation or truncation
9293 (insert_left_trunc_glyphs): Support GUI frames: make sure
9294 truncation glyphs overwrite enough glyphs from the current line to
9295 have sufficient space in pixels.
9296 (display_line): Support truncation and continuation glyphs on GUI
9297 frames. If some spare pixels are left on the line after inserting
9298 the truncation glyphs, fill that space with a stretch glyph of a
9299 suitably computed width.
9301 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9302 produce_glyphs, to support GUI sessions.
9304 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9306 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9308 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9310 Do not require float-time's arg to fit in time_t (Bug#11825).
9311 This works better on hosts where time_t is unsigned, and where
9312 float-time is applied to the (negative) difference between two times.
9313 * editfns.c (decode_time_components): Last arg is now double *,
9314 not int *, and means to store all the result as a double, without
9315 worrying about whether the seconds part fits in time_t.
9316 All callers changed.
9317 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9318 All callers changed.
9319 (Ffloat_time): Do not fail merely because the specified time falls
9320 outside of time_t range.
9322 2012-07-07 Glenn Morris <rgm@gnu.org>
9324 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9325 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9326 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9328 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9330 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9331 Update dependencies.
9333 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9335 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9337 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

9339 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9340 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9341 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9342 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9344 * xfont.c (compare_font_names): Redo to omit the need for casts.
9346 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9348 * xfns.c (Fx_change_window_property): Doc fix.
9349 * w32fns.c (Fx_change_window_property): Doc fix.
9351 * w32fns.c (Fx_window_property): Accept the same arguments as the
9352 X Windows version. Doc fix.
9353 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9355 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9356 Eli Zaretskii <eliz@gnu.org>
9358 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9359 Windows-specific code from nt/config.nt moved here.
9360 Obsolete settings removed.
9362 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9364 * process.c: Avoid unnecessary calls to gettime.
9365 (wait_reading_process_output): Don't get the time of day
9366 when gobbling data immediately and not waiting, as there's no need
9367 for it in that case. This removes a FIXME.
9369 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9371 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9372 is defined (Bug#11768).
9374 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9376 Fix marker debugging code.
9377 * marker.c (byte_char_debug_check): Do not perform the check
9378 if buffer is not multibyte.
9379 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9380 Call byte_char_debug_check with correct arguments.
9382 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9384 Compile marker debugging code only if ENABLE_CHECKING is defined.
9385 * marker.c (byte_char_debug_check, count_markers):
9386 Use only if ENABLE_CHECKING is defined.
9387 (byte_debug_flag): Remove.
9388 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9389 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9391 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9393 Avoid code repetition in marker-related functions.
9394 * marker.c (attach_marker): New function.
9395 (Fset_marker, set_marker_restricted, set_marker_both)
9396 (set_marker_restricted_both): Use it.
9397 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9398 Consistently rename charno to charpos.
9399 (marker_position): Add eassert.
9400 (marker_byte_position): Convert to eassert.

9418 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9419 * window.c (save_window_save): Likewise.
9421 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9423 Do not use Fdelete_overlay in delete_all_overlays
9424 to avoid redundant calls to unchain_overlay.
9425 * buffer.c (drop_overlay): New function.
9426 (delete_all_overlays, Fdelete_overlay): Use it.
9427 * minibuf.c (get_minibuffer): Fix comment.
9429 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9431 Port to OpenBSD 5.1 amd64.
9432 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9433 This is needed for OpenBSD, and should be harmless on all BSD systems.
9434 Also, include <sys/sysctl.h>, as it should be available on all
9435 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9436 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9437 use p_pid member, not kp_proc.pid.
9439 2012-07-06 Glenn Morris <rgm@gnu.org>
9441 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9443 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9445 More xmalloc and related cleanup.
9446 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9447 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
9448 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
9449 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
9450 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
9451 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
9452 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9453 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9454 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9456 Omit needless casts involving void * pointers and allocation.
9457 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9458 as the former is more robust if P's type is changed.
9459 Prefer xzalloc to xmalloc + memset 0.
9460 Simplify malloc-or-realloc to realloc.
9461 Don't worry about xmalloc returning a null pointer.
9462 Prefer xstrdup to xmalloc + strcpy.
9463 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9465 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9466 alloca of a constant.
9468 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9470 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9471 hscroll is larger than the line width. Fixes long and futile
9472 looping inside extend_face_to_end_of_line (on a TTY) producing
9473 glyphs that are not needed and thrown away.
9475 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

9489 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9490 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9491 followed by gtk_box_set_homogeneous (Bug#11768).
9492 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9493 (update_theme_scrollbar_width, xg_create_scroll_bar):
9494 Use gtk_scrollbar_new (Bug#11768).
9495 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9503 * xdisp.c (window_hscroll_limited): New function.
9504 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9505 coordinates when window's hscroll is set to insanely large
9508 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9510 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9511 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9513 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9516 * lisp.h (xzalloc): New prototype. Omit needless casts.
9517 * alloc.c (xzalloc): New function. Omit needless casts.

9519 xmalloc with following memset to xzalloc.

9571 * fileio.c (time_error_value): Check the right error number.
9572 Problem reported by Troels Nielsen in
9573 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9575 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9577 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9578 This should be fixed in a better way; see Eli Zaretskii in
9579 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9580 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9582 * fileio.c (time_error_value): Rename from special_mtime.
9583 The old name's problems were noted by Eli Zaretskii in
9584 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9586 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9587 This variable's comment says Emacs needs at least one GDB-visible
9588 symbol of type enum pvec_type, to work around GDB problems.
9589 The symbol's value doesn't matter.
9591 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9592 that causes compilation to fail on pre-C99 compilers.
9594 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9596 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9597 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9599 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9601 * buffer.c (init_buffer_once): Fix initialization of
9602 headers for buffer_defaults and buffer_local_symbols.
9603 Reported by Juanma Barranquero <lekktu@gmail.com>.
9605 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9607 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9608 * lisp.h (enum pvec_type): Use fewer bits.
9609 (PSEUDOVECTOR_SIZE_BITS): New constant.
9610 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9611 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9612 change in pvec_type.
9613 (PSEUDOVECTOR_TYPEP): New macro.
9614 (TYPED_PSEUDOVECTORP): Use it.
9615 * fns.c (internal_equal): Adapt code to extract pvectype.

9617 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9618 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9619 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9620 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9621 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9622 abusing vector->header.next.nbytes.
9623 (live_vector_p): Use PVEC_TYPE.
9624 (mark_object): Adapt code to extract pvectype. Use switch.
9626 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9628 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9629 Tighten new eassert a bit.
9631 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9633 Fix compilation with --enable-gcc-warnings and -O1
9635 * doprnt.c (doprnt): Change type of tem to int, initialize
9636 to avoid compiler warning. Add eassert.
9637 * search.c (simple_search): Initialize match_byte to avoid
9638 compiler warning. Add eassert.
9640 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9642 Avoid weird behavior with large horizontal scrolls.
9643 Without this change, for example, large hscroll values would
9644 mess up Emacs's display on Fedora 15 x86, presumably due to
9645 overflows in int calculations in the display code.
9646 Also, if buffers had long lines, Emacs would freeze.
9647 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9648 (set_window_hscroll): New function, containing the old guts of
9649 Fset_window_hscroll. Return the clipped value.
9650 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9651 This avoids the need to check against PTRDIFF_MAX.
9653 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9655 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9657 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9659 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9661 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9662 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9663 since GCC 4.4.6 issues a bogus warning for them.
9665 Fix bugs in file timestamp newness comparisons.
9666 * fileio.c (Ffile_newer_than_file_p):
9667 * lread.c (Fload): Use full timestamp resolution of files,
9668 not just the 1-second resolution, so that files that are only
9669 slightly newer still count as newer.
9670 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9671 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9673 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9675 * fileio.c: Improve handling of file time marker. (Bug#11852)
9676 (special_mtime): New function.
9677 (Finsert_file_contents, Fverify_visited_file_modtime):
9678 Use it to set special mtime values consistently.
9680 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9682 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9683 marker for non-existing file. (Bug#11852)
9685 2012-07-03 Glenn Morris <rgm@gnu.org>
9687 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9688 and did not make it into globals.h).
9690 2012-07-03 Tom Tromey <tromey@redhat.com>
9692 * window.c (Fset_window_margins, Fset_window_fringes)
9693 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9694 * textprop.c (Fprevious_property_change): No longer static.
9695 * syntax.c (Fsyntax_table_p): No longer static.

9724 * window.h: Remove EXFUNs.

9726 * xterm.h: Remove EXFUN.
9728 2012-07-03 Glenn Morris <rgm@gnu.org>
9730 * lisp.h (Frandom): Make it visible to C.
9731 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9732 buffer for invisible buffers. (Bug#1229)

9736 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9737 values which aren't power of 2.
9738 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9739 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9742 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9744 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9746 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9748 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9750 * alloc.c (allocate_vector_block): Remove redundant
9751 calls to mallopt if DOUG_LEA_MALLOC is defined.
9752 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9753 avoid calls to mallopt if zero_vector is returned.
9755 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9757 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9758 is enabled, avoid dereferencing NULL current_sblock if
9761 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9763 Cleanup basic buffer management.
9764 * buffer.h (struct buffer): Change layout to use generic vector
9765 marking code. Fix some comments. Change type of 'clip_changed'
9766 to bitfield. Remove unused #ifndef old.
9767 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9768 (GET_OVERLAYS_AT): Fix indentation.
9769 (for_each_per_buffer_object_at): New macro.

9773 * alloc.c (allocate_buffer): Adjust to match new layout of
9774 struct buffer. Fix comment.
9775 (mark_overlay): New function.

9777 Lisp area of struct buffer.
9778 (mark_object): Use it. Adjust marking of misc objects
9779 and related comments.
9781 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9783 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9784 wrapper that is not needed because the wrapped code is a no-op (zero
9785 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9786 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9788 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9790 * alloc.c (mark_buffer): Simplify. Remove prototype.
9791 (mark_object): Add comment. Reorganize marking of vector-like
9792 objects. Use CHECK_LIVE for all vector-like objects except buffers
9793 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9794 Avoid redundant calls to mark_vectorlike for bool vectors.
9796 2012-06-30 Glenn Morris <rgm@gnu.org>
9798 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9800 * epaths.in (PATH_SITELOADSEARCH): New.
9801 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9802 This is rather than relying on --enable-locallisppath elements
9803 having "site-lisp" in their names. (Bug#10208#25, 11658)
9805 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9807 * w32proc.c (sys_select): Accept and ignore one more argument.
9809 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9811 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9812 (pselect) [!MS_DOS]: Redirect to sys_select.
9814 * sysdep.c: Don't include dos.h and dosfns.h.
9816 * process.c (sys_select):
9817 * msdos.c (sys_select): Accept one more argument and ignore it.
9819 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9820 adapt data types and code to that.
9823 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9824 which clashes with the gnulib function of the same name.
9826 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9828 * font.c (font_style_to_value, font_style_symbolic)
9829 (font_prop_validate_style): Add type checks for values in
9832 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9834 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9837 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9839 * xdisp.c (try_window_id): Undo last change.
9841 * w32.c (getwd): Adjust commentary about startup_dir.
9842 (init_environment): Always call sys_access, even in non-MSVC
9843 builds. Don't chdir to the directory of the Emacs executable.
9844 This undoes code from 1997 which was justified by the need to
9845 "avoid conflicts when removing and renaming directories". But its
9846 downside was that every relative file name was being interpreted
9847 relative to the directory of the Emacs executable, which can never
9848 be TRT. In particular, it broke sys_access when called with
9849 relative file names.
9850 (sys_access): Map GetLastError to errno.
9852 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9854 * window.h (struct window): Change type of 'fringes_outside_margins'

9858 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9861 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9863 * gnutls.c (emacs_gnutls_handshake):
9864 Add QUIT to make the loop interruptible.
9866 2012-06-29 Glenn Morris <rgm@gnu.org>
9868 * charset.c (init_charset): Make lack of etc/charsets fatal.
9870 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9872 * editfns.c (region_limit): Fix type mismatch.
9874 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9876 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9877 undefined. Convert from xassert to eassert.
9878 * nsmenu.m: Convert from xassert to eassert.
9879 * nsterm.m: Likewise.
9881 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9883 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9885 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9887 Avoid integer overflow on scroll-left and scroll-right.
9888 * window.c (HSCROLL_MAX): New macro.
9889 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9890 overflow when requested scroll falls outside ptrdiff_t range.
9892 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9894 * window.h (struct window): Change type of 'hscroll',
9895 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9896 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9897 Adjust users accordingly.
9898 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9899 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9900 from EMACS_INT to ptrdiff_t.
9901 (make_window): Omit redundant initialization.
9903 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9907 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9909 * window.h (struct window): Change type of 'use_time' and
9910 'sequence_number' from Lisp_Object to int.

9918 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9919 enabled with --enable-checking=[all,glyphs] configure option.
9920 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9921 adjust comments accordingly.

9977 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9978 as in make_pure_string and make_pure_c_string.
9980 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9982 * alloc.c (allocate_string): Fix last change.
9984 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

10034 * alloc.c: Remove build_string.
10035 * lisp.h: Define build_string as static inline. This provides
10036 a better opportunity to optimize away calls to strlen when the
10037 function is called with compile-time constant argument.
10038 * image.c (imagemagick_error): Convert to build_string.
10039 * w32proc.c (sys_spawnve): Likewise.
10040 * xterm.c (x_term_init): Likewise.
10042 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10044 Use sprintf return value instead of invoking strlen on result.
10045 In the old days this wasn't portable, since some sprintf
10046 implementations returned char *. But they died out years ago and
10047 Emacs already assumes sprintf returns int.
10048 Similarly for float_to_string.
10049 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10050 * ccl.c (ccl_driver):

10054 * print.c (print_object):
10055 * xdisp.c (message_dolog):
10056 * xfns.c (syms_of_xfns):
10057 Use sprintf or float_to_string result to avoid need to call strlen.
10058 * data.c (Fnumber_to_string):
10059 Use make_unibyte_string, since the string must be ASCII.
10060 * lisp.h, print.c (float_to_string): Now returns int length.
10061 * term.c (produce_glyphless_glyph):
10062 Use sprintf result rather than recomputing it.
10064 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10065 * Makefile.in (ALL_CFLAGS):
10066 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10067 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10069 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10071 * dispextern.h (xstrcasecmp): Define to library function
10072 strcasecmp if available.

10088 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10090 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10091 sprintf already null-terminates its output.
10093 * xfns.c (x_window): Remove redundant cast.
10095 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10097 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10098 `const char *' to `char *' to avoid compiler warning.
10100 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10102 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10103 instead of truncating it to 63 (admittedly a generous limit).
10105 * process.c: Fix spelling and caps in comments.
10107 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10109 * emacs.c (setpgrp): Remove definition, unused.

10123 * s/ms-w32.h (struct timespec): Definition moved from
10124 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

10156 Remove unnecessary forward decls.
10158 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10160 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10161 * lisp.h (WAIT_READING_MAX): New macro.
10162 * dispnew.c (Fsleep_for, sit_for):
10163 * keyboard.c (kbd_buffer_get_event):
10164 * process.c (Faccept_process_output):
10165 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10166 This improves on the previous patch, which introduced a bug
10167 when time_t is unsigned and as wide as intmax_t.
10168 See <http://bugs.gnu.org/9000#51>.
10170 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10172 * dispnew.c (sit_for, Fsleep_for):
10173 * keyboard.c (kbd_buffer_get_event):

10188 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10190 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10191 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10193 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10195 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10196 last argument of make_unibyte_string.
10198 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10199 language ID in the event parameters.
10201 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10202 event.code, not the obscure "character set ID".
10204 2012-06-23 Chong Yidong <cyd@gnu.org>
10206 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10229 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10230 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10231 Don't assume EMACS_TIME and struct timeval are the same type.
10233 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10235 Support higher-resolution time stamps (Bug#9000).
10236 The time stamps are only nanosecond-resolution at the C level,
10237 since that's the best that any real-world system supports now.
10238 But they are picosecond-resolution at the Lisp level, as that's
10239 easy, and leaves room for future OS improvements.
10241 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10244 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10245 Don't get current time unless it's needed.
10247 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10248 now provides it if it's absent.
10249 (start_atimer): Port to higher-res time stamps.
10250 Check for time stamp overflow. Don't get current time more
10251 often than is needed.
10253 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10254 Include systime.h, not time.h.
10255 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10257 * dired.c: Include stat-time.h.
10258 (Ffile-attributes): File times now have higher resolution.
10260 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10261 (struct image): Timestamp now has higher resolution.
10263 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10264 has at least microseconds now. All uses removed.
10265 (update_frame, update_single_window, update_window, update_frame_1)
10266 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10267 (duration_to_sec_usec): Remove; no longer needed.
10269 * editfns.c (time_overflow): Now extern.
10270 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10271 (float-time, Fformat_time_string, Fcurrent_time_string)
10272 (Fcurrent_time_zone): Accept and generate higher-resolution
10274 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10275 (decode_time_components, lisp_seconds_argument): New functions.
10276 (make_time): Now static.
10277 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10278 Report an error if the time is invalid, rather than having the caller
10281 * fileio.c: Include <stat-time.h>
10282 (Fcopy_file): Copy higher-resolution time stamps.
10283 Prefer to set the time stamp via a file descriptor if that works.
10284 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10285 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10286 (Fvisited_file_modtime, Fset_visited_file_modtime):
10287 Support higher-resolution time stamps.
10289 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10291 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10293 * image.c (prepare_image_for_display, clear_image_cache)
10294 (lookup_image): Port to higer-resolution time stamps.
10296 * keyboard.c (start_polling, bind_polling_period):
10297 Check for time stamp overflow.
10298 (read_char, kbd_buffer_get_event, timer_start_idle)
10299 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10300 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10301 Port to higher-resolution time stamps. Do not assume time_t is signed.
10302 (decode_timer): New function. Timers are now vectors of length 9,
10303 not 8, to accommodate the picosecond component.
10304 (timer_check_2): Use it.
10306 * nsterm.m (select_timeout, timeval_subtract): Remove.
10307 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10308 as they're a bit more accurate and handle overflow better.
10309 (ns_select): Change prototype to be compatible with pselect.
10310 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10311 * nsterm.h (ns_select): Adjust prototype.
10313 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10314 us-resolution time stamps.
10315 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10317 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10319 * lisp.h (time_overflow): New decl.
10320 (wait_reading_process_output): First arg is now intmax_t, not int,
10321 to accommodate larger waits.
10323 * process.h (struct Lisp_Process.read_output_delay):
10324 Now counts nanoseconds, not microseconds.
10325 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10327 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10328 (wait_reading_process_output):
10329 Port to ns-resolution time stamps.
10330 (Faccept_process_output, wait_reading_process_output):
10331 Check for time stamp overflow. Do not assume time_t is signed.
10332 (select_wrapper): Remove; we now use pselect.
10333 (Fprocess_attributes): Now generates ns-resolution time stamps.
10335 * sysdep.c: Include utimens.h. Don't include utime.h
10336 or worry about struct utimbuf; gnulib does that for us now.
10337 (gettimeofday): Remove; gnulib provides a substitute.
10338 (make_timeval): New function.
10339 (set_file_times): Now sets ns-resolution time stamps.
10340 New arg FD; all uses changed.
10341 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10342 (system_process_attributes):
10343 Now returns ns-resolution time stamp. All uses changed.
10344 Check for time stamp overflow.
10346 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10347 provides a substitute now.
10349 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10350 since it guarantees struct timespec.
10351 (EMACS_TIME): Now struct timespec, so that we can support
10352 ns-resolution time stamps.
10353 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10354 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10355 (EMACS_USECS): Remove.
10356 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10357 so multiply the arg by 1000 before storing it.
10358 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10360 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10361 Port to ns-resolution time stamps.
10362 (EMACS_TIME_NEG_P): Remove; replaced by....
10363 (EMACS_TIME_SIGN): New macro.
10364 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10365 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10366 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10367 (make_timeval, make_lisp_time, decode_time_components): New decls.
10368 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10369 that it mishandled time_t overflow. You can't compare by subtracting!
10370 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10371 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10373 * term.c: Include <sys/time.h>.
10374 (timeval_to_Time): New function, for proper overflow wraparound.
10375 (term_mouse_position, term_mouse_click): Use it.
10377 * undo.c (record_first_change): Support higher-resolution time stamps
10378 in the undo buffer.
10379 (Fprimitive_undo): Use them when restoring time stamps.
10381 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10382 (w32_get_internal_run_time):
10383 Port to higher-resolution Emacs time stamps.
10384 (ltime): Now accepts single 64-bit integer, as that's more convenient
10387 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10389 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10390 for compatibility with pselect. Support ns-resolution time stamps.
10392 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10394 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10395 Check for time stamp overflow, and support ns-resolution time stamps.
10397 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10398 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10399 (timeval_subtract): Remove; no longer needed.
10400 (XTflash, XTring_bell, x_wait_for_event):
10401 Port to ns-resolution time stamps. Don't assume time_t is signed.
10403 2012-06-22 Chong Yidong <cyd@gnu.org>
10405 * xdisp.c (x_consider_frame_title): Revert last change.
10407 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10409 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10410 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10411 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10412 staticidx goes up to 1597 out of 1600 = 0x640.)
10414 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10416 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10417 Otherwise, the umask might be mistakenly 0 while handling input signals.
10419 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10421 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10687 Use an inline function on all platforms when using the union type,

10833 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10834 would mishandle a string argument "Xc" if X was a multibyte

10872 (Fbuffer_local_value): Use it.
10873 (Vmode_line_format): Docstring tweaks.
10875 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10877 * sysdep.c (system_process_attributes): Improve comment.
10879 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
10881 * keyboard.c: Export real-this-command to Elisp.
10882 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
10883 and DEFVAR it. Update all users.
10885 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
10887 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10889 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10890 Convert pctcpu and pctmem to Lisp float properly.
10891 Let the compiler fold better, as 100.0/0x8000 is exact.
10893 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10895 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10898 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
10900 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
10902 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10904 For a 'struct window', replace some Lisp_Object fields to
10905 bitfields where appropriate, remove unused fields.
10906 * window.h (struct window): Remove unused 'last_mark_x' and
10907 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10908 change its type from Lisp_Object to bitfield.
10909 Change type of 'force_start', 'optional_new_start',
10910 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10911 fields from Lisp_Object to bitfield. Adjust users accordingly.
10913 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10915 Pacify gcc -Wdouble-precision when using Xaw.
10916 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10917 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10918 Use 'float' consistently, rather than 'float' in most places
10919 and 'double' in a couple of places.
10921 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10923 * xdisp.c (handle_stop): Detect whether we have overlay strings
10924 loaded by testing it->current.overlay_string_index to be
10925 non-negative, instead of checking whether n_overlay_strings is
10926 positive. (Bug#11587)
10928 2012-05-31 Chong Yidong <cyd@gnu.org>
10930 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10932 * doc.c (Fsubstitute_command_keys): Doc fix.
10934 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10936 * search.c (search_buffer): Remove calls to
10937 r_alloc_inhibit_buffer_relocation, as it is now called by
10938 maybe_unify_char, which was the cause of relocation of buffer text
10941 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10943 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10944 for the duration of call to load_charset, to avoid problems with
10945 callers of maybe_unify_char that access buffer text through C
10948 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10949 decrement the inhibition flag, instead of just setting or
10952 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10954 Remove obsolete '#define static' cruft.
10955 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10956 This #undef was "temporary" in 2000; it is no longer needed
10957 now that '#define static' has gone away.
10958 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10959 (gray_bitmap_bits): Remove; no longer needed.
10960 All uses replaced with definiens.
10961 * xterm.c: Include "bitmaps/gray.xbm".
10963 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10965 Clean up __executable_start, monstartup when --enable-profiling.
10966 The following changes affect the code only when profiling.
10967 * dispnew.c (__executable_start): Rename from safe_bcopy.
10968 Define only on platforms that need it.
10969 * emacs.c: Include <sys/gmon.h> when profiling.
10970 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10971 (__executable_start): Remove decl, since lisp.h does it now.
10972 (safe_bcopy): Remove decl; no longer has that name.
10973 (main): Coalesce #if into single bit of code, for simplicity.
10974 Cast pointers to uintptr_t, since standard libraries want integers
10976 * lisp.h (__executable_start): New decl.
10978 2012-05-31 Glenn Morris <rgm@gnu.org>
10980 * image.c (Fimagemagick_types): Doc fix.
10982 2012-05-30 Jim Meyering <meyering@redhat.com>
10984 * callproc.c (Fcall_process_region): Include directory component
10985 in mkstemp error message (Bug#11586).
10987 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10989 * alloc.c, lisp.h (make_pure_vector): Now static.
10991 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10993 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10994 Move to byte-run.el.

10996 * data.c (Fdefalias): Purify definition, except for keymaps.
10997 (Qdefun): Move from eval.c.
10998 * lisp.h (Qdefun): Remove.
10999 * lread.c (read1): Tiny simplification.
11001 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11003 Do not create empty overlays with the evaporate property (Bug#9642).
11004 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11005 Bug#9642, but explicitly check that the buffer the overlay would
11006 be moved to is live and rearrange lines to make sure that errors
11007 will not put the overlay in an inconsistent state.
11008 (Fdelete_overlay): Cosmetics.
11010 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11012 * w32term.c (my_bring_window_to_top): New function.
11013 (x_raise_frame): Use handle returned by DeferWindowPos, which
11014 could be different from the original one.
11015 Call my_bring_window_to_top instead of my_set_foreground_window.
11018 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11019 by calling BringWindowToTop.
11021 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

11024 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11026 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11027 This avoids undefined behavior that might cause the eassert
11028 to not catch an out-of-range value.
11030 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11032 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11033 Update dependencies.
11035 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11037 * bidi.c (bidi_mirror_char): Fix last change.
11039 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11041 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11042 when referring to sectname field in printf format.
11044 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11046 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11047 Only r_alloc_inhibit_buffer_relocation needed to be added;
11048 the others were already declared.
11050 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11051 before checking whether it's out of range. Put the check inside
11053 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11055 2012-05-27 Ken Brown <kbrown@cornell.edu>
11057 * callproc.c (Fcall_process): Restore a line that was accidentally
11058 commented out in the 2011-02-13 change (bug#11547).
11060 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11062 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11063 defined on ralloc.c.
11065 * buffer.c [REL_ALLOC]: Remove prototypes of
11066 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11067 they are now on lisp.h.
11069 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11071 * search.c (search_buffer): Use it to inhibit relocation of buffer
11072 text while re_search_2 is doing its job, because re_search_2 is
11073 passed C pointers to buffer text. (Bug#11519)
11075 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11076 Update value to 24.
11078 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11079 state after an additional call to move_it_in_display_line_to, keep
11080 the values of it->max_ascent and it->max_descent found for the
11082 (pos_visible_p): Revert the comparison against bottom_y to what it
11083 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11086 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11088 Fix coding-related core dumps with gcc -ftrapv.
11089 The code was computing A - B, where A and B are pointers, and B is
11090 random garbage. This can lead to core dumps on platforms that
11091 have special pointer registers, and it also leads to core dumps on
11092 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11093 A - B only when B is initialized properly.
11094 * coding.c (coding_set_source, coding_set_destination): Return void.
11095 (coding_change_source, coding_change_destinations): New functions,
11096 with the old behaviors of coding_set_source and coding_set_destination.
11097 All callers that need an offset changed to use these new functions.
11099 2012-05-26 Glenn Morris <rgm@gnu.org>
11101 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11103 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11105 Extend mouse support on W32 text-mode console.
11106 * xdisp.c (draw_row_with_mouse_face):
11107 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11109 * w32console.c: Include window.h.
11110 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11112 (initialize_w32_display): Initialize mouse-highlight data.
11114 * w32inevt.c: Include termchar.h and window.h.
11115 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11116 moves, call note_mouse_highlight. If help_echo changed, call
11117 gen_help_event to produce help-echo message in the echo area.
11118 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11121 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11123 * lread.c (read1): Simplify slightly to avoid an overflow warning
11124 with GCC 4.7.0 on x86-64.
11126 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11128 * bidi.c (bidi_mirror_char): Revert last change: an int is
11129 definitely wide enough here.
11131 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11133 Fix integer width and related bugs (Bug#9874).
11134 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11135 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11136 (string_bytes, check_sblock, allocate_string_data):
11137 (compact_small_strings, Fmake_bool_vector, make_string)
11138 (make_unibyte_string, make_multibyte_string)
11139 (make_string_from_bytes, make_specified_string)
11140 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11141 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11143 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11144 (allocate_pseudovector):
11145 Use int, not EMACS_INT, where int is wide enough.
11146 (inhibit_garbage_collection, Fgarbage_collect):
11147 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11148 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11149 int might not be wide enough.
11150 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11151 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11152 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11153 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11154 (bidi_level_of_next_char, bidi_move_to_visually_next):
11155 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11156 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11157 (Fkill_buffer, Fset_buffer_major_mode)
11158 (advance_to_char_boundary, Fbuffer_swap_text)
11159 (Fset_buffer_multibyte, overlays_at, overlays_in)
11160 (overlay_touches_p, struct sortvec, record_overlay_string)
11161 (overlay_strings, recenter_overlay_lists)
11162 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11163 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11164 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11165 (Foverlay_recenter, last_overlay_modification_hooks_used)
11166 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11167 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11168 (validate_region): Omit unnecessary test for b <= e,
11169 since that's guaranteed by the previous test.
11170 (adjust_overlays_for_delete): Avoid pos + length overflow.
11171 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11172 (report_overlay_modification):
11173 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11174 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11175 Omit pointer cast, which isn't needed anyway, and doesn't work
11176 after the EMACS_INT -> ptrdiff_t change.
11177 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11178 * buffer.h: Adjust decls to match defn changes elsewhere.
11179 (struct buffer_text, struct buffer):
11180 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11181 Use EMACS_INT, not int, where int might not be wide enough.
11182 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11183 not int, to avoid needless 32-bit limit on 64-bit hosts.
11184 (exec_byte_code): Use tighter memory-full test, one that checks
11185 for alloca overflow. Don't compute the address of the object just
11186 before an array, as that's not portable. Use EMACS_INT, not
11187 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11188 * callint.c (Fcall_interactively):
11189 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11190 * callproc.c (call_process_kill, Fcall_process):
11191 Don't assume pid_t fits into an Emacs fixnum.
11192 (call_process_cleanup, Fcall_process, child_setup):
11193 Don't assume pid_t fits into int.
11194 (call_process_cleanup, Fcall_process, delete_temp_file)
11195 (Fcall_process_region):
11196 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11197 (Fcall_process): Simplify handling of volatile integers.
11198 Use int, not EMACS_INT, where int will do.
11199 * casefiddle.c (casify_object, casify_region, operate_on_word)
11200 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11201 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11202 (casify_object): Avoid integer overflow when overallocating buffer.
11203 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11204 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11205 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11206 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11207 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11208 integers are now checked earlier. All uses replaced with XINT.
11210 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11211 For CCL_MapSingle, check that content and value are in int range.
11212 (ccl_driver, Fregister_code_conversion_map):
11213 Check that Vcode_version_map_vector is a vector.
11214 (resolve_symbol_ccl_program): Check that vector header is in range.
11215 Always copy the vector, so that we can check its contents reliably
11216 now rather than having to recheck each instruction as it's being
11217 executed. Check that vector words fit in 'int'.
11218 (ccl_get_compiled_code, Fregister_ccl_program)
11219 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11220 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11221 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11222 contents are in range.
11223 (Fccl_execute_on_string): Check that status is in range.
11224 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11225 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11226 Accept and return EMACS_INT, not int, because callers can pass values
11227 out of 'int' range.
11228 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11229 (multibyte_chars_in_text, parse_str_as_multibyte)
11230 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11231 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11232 (string_escape_byte8, Fget_byte):
11233 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11234 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11235 avoid mishandling large integers.
11236 * character.h: Adjust decls to match defn changes elsewhere.
11237 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11238 (Ffind_charset_region):
11239 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11240 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11241 (load_charset_map_from_vector, Fdefine_charset_internal):
11242 Don't assume fixnum fits in int.
11243 (load_charset_map_from_vector, Fmap_charset_chars):
11244 Remove now-unnecessary CHECK_NATNUMs.
11245 (Fdefine_charset_internal): Check ranges here, more carefully.
11246 Don't rely on undefined behavior with signed left shift overflow.
11247 Don't assume unsigned int fits into fixnum, or that fixnum fits
11248 into unsigned int. Don't require max_code to be a valid fixnum;
11249 that's not true for gb10830 4-byte on a 32-bit host. Allow
11250 invalid_code to be a cons, for the same reason. Require code_offset
11251 to be a character. Avoid int overflow if max_char is close
11253 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11254 this is intended anyway and avoids some undefined behavior.
11255 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11256 INDEX_TO_CODE_POINT, as that's what it expects.
11257 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11258 * charset.h (DECODE_CHAR): Return int, not unsigned;
11259 this is what was intended anyway, and it avoids undefined behavior.
11260 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11261 integer-overflow issues.
11262 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11263 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11264 where the argument is EMACS_INT, and this behavior is not intended.
11265 * chartab.c (Fmake_char_table, Fset_char_table_range)
11266 (uniprop_get_decoder, uniprop_get_encoder):
11267 Don't assume fixnum fits in int.
11268 * cmds.c (move_point): New function, that does the gist of
11269 Fforward_char and Fbackward_char, but does so while checking
11270 for integer overflow more accurately.
11271 (Fforward_char, Fbackward_char): Use it.
11272 (Fforward_line, Fend_of_line, internal_self_insert)
11273 (internal_self_insert):
11274 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11275 Fix a FIXME, by checking for integer overflow when calculating
11276 target_clm and actual_clm.
11277 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
11278 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)
11279 (ASSURE_DESTINATION, coding_alloc_by_realloc)
11280 (coding_alloc_by_making_gap, alloc_destination)

11961 Move its few remaining bits of functionality to where they're needed.
11962 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11963 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11964 * m/template.h: Remove.
11965 * Makefile.in (M_FILE): Remove. All uses removed.
11966 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11967 * lisp.h (USE_LSB_TAG):
11968 * mem-limits.h (EXCEEDS_LISP_PTR):
11969 Use VAL_MAX, not VALBITS, in #if.
11970 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11971 (EMACS_UINT): Define unconditionally now.
11972 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11973 (BITS_PER_EMACS_INT): New constants, replacing
11974 what used to be in config.h, but not useful in #if.
11975 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11976 define them any more.
11977 (VAL_MAX): New macro.
11979 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11980 BITS_PER_EMACS_INT, in #if.
11981 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11982 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11983 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11984 * s/ms-w32.h (DATA_START):
11985 Move here from removed file m/intel386.h.
11986 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11987 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11989 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11991 Assume C89 or later.
11992 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11993 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11995 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
11996 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11997 * textprop.c, tparam.c (NULL): Remove.
11998 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11999 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12000 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12001 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12002 * xterm.c (input_signal_count): Assume volatile works.
12004 2012-05-21 Ken Brown <kbrown@cornell.edu>
12006 * xgselect.c (xg_select): Fix first argument in call to 'select'
12009 2012-05-20 Ken Brown <kbrown@cornell.edu>
12011 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12012 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12014 2012-05-19 Ken Brown <kbrown@cornell.edu>
12016 * xfns.c (x_in_use): Remove `static' qualifier.
12017 * xterm.h (x_in_use): Declare.
12018 * xgselect.c: Include xterm.h.
12019 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12020 and `display_arg' (bug#9754).
12022 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12024 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12026 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12027 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12029 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12031 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12033 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12034 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12036 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12037 reference to image_cache->refcount.
12038 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12040 2012-05-17 Juri Linkov <juri@jurta.org>
12042 * search.c (Fword_search_regexp, Fword_search_backward)
12043 (Fword_search_forward, Fword_search_backward_lax)
12044 (Fword_search_forward_lax): Move functions to isearch.el
12045 (bug#10145, bug#11381).
12047 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12049 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12051 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12053 * lread.c (init_obarray): Declare Qt and Qnil as special.
12055 2012-05-14 Glenn Morris <rgm@gnu.org>
12057 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12058 Put "libexec" before "bin", for the sake of init_callproc_1.
12060 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12062 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12064 * unexaix.c: Port to more-recent AIX compilers.
12065 (report_error, report_error_1, make_hdr, copy_sym)
12066 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12067 Make arguments const char *, not char *, to avoid violations of C
12068 standard and to fix some AIX warnings reported by Gilles Pion.
12070 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12072 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12073 already have overlays loaded.
12074 (handle_single_display_spec): Before returning without displaying
12075 fringe bitmap, synchronize the bidi iterator with the main display
12076 iterator, by calling iterate_out_of_display_property.
12077 (iterate_out_of_display_property): Detect buffer iteration by
12078 testing that it->string is a Lisp string.
12079 (get_next_display_element): When the current object is exhausted,
12080 and there's something on it->stack, call set_iterator_to_next to
12081 proceed with what's on the stack, instead of returning zero.
12082 (set_iterator_to_next): If called at the end of a Lisp string,
12083 proceed to consider_string_end without incrementing string
12084 position. Don't increment display vector index past the end of
12085 the display vector. (Bug#11417)
12086 (pos_visible_p): Don't report a position visible when move_it_to
12087 stopped at the last line of window, which happens to be scanned
12088 backwards by the bidi iteration. (Bug#11464)
12090 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12092 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12093 and right-margin display specs even if the spec is invalid or we
12094 are on a TTY, and thus unable to display on the fringes.
12095 That's because the text with the property will not be displayed anyway,
12096 so we need to signal to the caller that this is a "replacing"
12097 display spec. This fixes display when the spec is invalid or we
12100 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12102 * unexaix.c (make_hdr): Fix typo in prototype.
12103 This bug broke the build on AIX. Problem reported by Gilles Pion.
12105 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12107 * keyboard.c (kbd_buffer_get_event): Read special events also in
12108 batch mode. (Bug#11415)
12110 2012-05-12 Glenn Morris <rgm@gnu.org>
12112 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12114 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12116 * lisp.mk (lisp): Add newcomment.elc.
12118 2012-05-12 Glenn Morris <rgm@gnu.org>
12120 * Makefile.in (MKDIR_P): New, set by configure.
12121 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12123 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12125 Remove unused function hourglass_started.
12126 * dispextern.h (hourglass_started):
12127 * w32fns.c (hourglass_started):
12128 * xdisp.c (hourglass_started): Remove.
12130 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12132 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12133 Update dependencies.
12135 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12137 * xgselect.c (xg_select): Put maxfds+1 into a var.
12138 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12140 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12142 2012-05-10 Dave Abrahams <dave@boostpro.com>
12144 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12145 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12147 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12149 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12150 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12151 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12152 Initialize xd_registered_buses.
12154 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12156 Untag more efficiently if USE_LSB_TAG.
12157 This is based on a proposal by YAMAMOTO Mitsuharu in
12158 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12159 For an admittedly artificial (nth 8000 longlist) benchmark on
12160 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12161 Emacs's overall text size by 1%.
12162 * lisp.h (XUNTAG): New macro.
12163 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12164 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12165 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12166 * eval.c (Fautoload):
12167 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12168 * frame.h (XFRAME): Use XUNTAG.
12170 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12171 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12172 Remove unportable assumptions about print widths of types like
12174 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12175 intptr_t when converting between pointer and integer, to avoid GCC
12176 warnings about wrong width.
12178 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12180 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12181 stack for each reader_thread, instead of defaulting to 8MB
12182 determined by the linker. This avoids failures in creating
12183 subprocesses on Windows 7, see the discussion in this thread:
12184 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12186 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12188 Fix up display of the *Minibuf-0* buffer in the mini window.
12189 * keyboard.c (read_char): Don't clear the echo area if there's no
12191 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12192 contents of *Minibuf-0*) if there's no message displayed in its stead.
12194 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12196 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12199 2012-05-06 Chong Yidong <cyd@gnu.org>
12201 * lisp.mk (lisp): Update.
12203 2012-05-05 Jim Meyering <meyering@redhat.com>
12205 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12207 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12209 * data.c (PUT_ERROR): New macro.
12210 (syms_of_data): Use it. Add new error type `user-error'.
12211 * undo.c (user_error): New function.
12212 (Fprimitive_undo): Use it.
12213 * print.c (print_error_message): Adjust print style for `user-error'.
12214 * keyboard.c (user_error): New function.
12215 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12217 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12219 Do not limit current-time-string to years 1000..9999.
12220 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12221 (Fcurrent_time_string): Support any year that is supported by the
12222 underlying localtime representation. Don't use asctime, as it
12223 has undefined behavior for years outside the range -999..9999.
12225 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12227 Fix race conditions involving setenv, gmtime, localtime, asctime.
12228 Without this fix, interrupts could mess up code that uses these
12229 nonreentrant functions, since setting TZ invalidates existing
12230 tm_zone or tzname values, and since most of these functions return
12231 pointers to static storage.
12232 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12233 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12234 Grow the critical sections to include not just invoking
12235 localtime/gmtime, but also accessing these functions' results
12236 including their tm_zone values if any, and any related TZ setting.
12237 (format_time_string): Last arg is now struct tm *, not struct tm **,
12238 so that the struct tm is saved in the critical section.
12239 All callers changed. Simplify allocation of initial buffer, partly
12240 motivated by the fact that memory allocation needs to be outside
12241 the critical section.
12243 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12245 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12246 with RESET_INTERVAL.
12248 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12249 Remove duplicated buffer name initialization.
12251 2012-05-02 Jim Meyering <jim@meyering.net>
12253 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12255 * xfns.c (x_window): Use xstrdup (Bug#11375).
12257 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12259 * xdisp.c (pos_visible_p): If already at a newline from the
12260 display string before the 'while' loop, don't walk back the glyphs
12261 from it3.glyph_row. Solves assertion violation when the display
12262 string begins with a newline (egg.el). (Bug#11367)
12264 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12266 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12269 2012-05-01 Glenn Morris <rgm@gnu.org>
12271 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12272 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12273 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12274 All were removed before 23.1.
12276 * dispnew.c: Remove HAVE_LIBNCURSES test;
12277 it is always true on relevant platforms.
12279 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12280 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12282 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12284 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12286 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12287 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12290 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12292 Do not avoid creating empty evaporating overlays (Bug#9642).
12293 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12294 That is, do not delete an evaporating overlay if it becomes
12295 empty after its bounds are adjusted to fit within its buffer.
12296 This fix caused other problems, and I'm reverting it until we get
12297 to the bottom of them.
12299 2012-04-27 Chong Yidong <cyd@gnu.org>
12301 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12303 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12305 * xdisp.c (pos_visible_p): If the window start position is beyond
12306 ZV, start the display from buffer beginning. Prevents assertion
12307 violation in init_iterator when the minibuffer window is scrolled
12308 via the scroll bar.
12310 * window.c (window_scroll_pixel_based): Likewise.
12312 2012-04-27 Chong Yidong <cyd@gnu.org>
12314 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12316 2012-04-27 Glenn Morris <rgm@gnu.org>
12318 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12319 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12321 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12323 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12324 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12326 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12328 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12329 display element, check also the underlying string or buffer
12330 character. (Bug#11341)
12332 * w32menu.c: Include w32heap.h.
12333 (add_menu_item): If the call to AppendMenuW (via
12334 unicode_append_menu) fails, disable Unicode menus only if we are
12335 running on Windows 9X/Me.
12337 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12339 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12340 (xgetint): Add missing shift for LSB tags.
12342 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12344 * keyboard.c (read_char): Don't wipe echo area for select window
12345 events: These might get delayed via `mouse-autoselect-window'
12348 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12350 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12351 manipulation of :loaded-from data.
12353 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12355 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12356 now a cons (bug#11311).
12358 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12360 Do not create empty overlays with the evaporate property (Bug#9642).
12361 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12362 if it becomes empty after its bounds are adjusted to fit within
12363 its buffer. Without this fix, in a nonempty buffer (let ((o
12364 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12365 yields an empty overlay that has the evaporate property, which is
12366 not supposed to happen.
12368 Fix minor GTK3 problems found by static checking.
12369 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12370 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12371 (struct _EmacsFixedClass, emacs_fixed_get_type):
12372 Move decls here from emacsgtkfixed.h, since they needn't be public.
12373 (emacs_fixed_get_type): Now static.
12374 (emacs_fixed_class_init): Omit unused local.
12375 (emacs_fixed_child_type): Remove; unused.
12376 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12377 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12378 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12379 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12380 (EMACS_FIXED_GET_CLASS): Remove; unused.
12381 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12383 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12384 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12386 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12388 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12389 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12390 (__malloc_size_t, __malloc_ptrdiff_t):
12391 Remove. All uses removed, replaced by the definiens if needed,
12392 since we can assume C89 or better now.
12393 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
12394 (protect_malloc_state, align, get_contiguous_space)

12481 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12483 * sysdep.c [__FreeBSD__]: Minor cleanups.
12484 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12485 Use Emacs indenting style more consistently. Avoid some casts.

12569 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12570 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12571 (NEED_MEM_INSERT): New macro.
12572 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12573 Remove one incorrect comment and fix another.

12609 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12610 * s/netbsd.h, s/sol2-6.h:
12611 Remove definition of GC_MARK_STACK, since the default now works.
12612 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12640 2012-04-11 Daniel Colascione <dancol@dancol.org>
12642 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12643 against is gone. It's better to use vfork now so that when Cygwin
12644 gains a new, working vfork, we use it automatically (bug#10398).
12646 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12667 being loaded (bug#10424).
12669 2012-04-09 Glenn Morris <rgm@gnu.org>
12671 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

12692 2012-04-09 Chong Yidong <cyd@gnu.org>
12694 * eval.c (Fuser_variable_p, user_variable_p_eh)

12699 * minibuf.c (Fread_variable): Callers changed.
12701 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12703 * xdisp.c (set_cursor_from_row): If the display string appears in
12704 the buffer at position that is closer to point than the position
12705 after the display string, display the cursor on the first glyph of
12706 the display string. Fixes cursor display when a 'display' text
12707 property immediately follows invisible text. (Bug#11094)
12709 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12711 composite.c: use 'double' consistently
12712 * composite.c (get_composition_id): Use 'double' consistently
12713 instead of converting 'float' to 'double' and vice versa; this is
12714 easier to understand and avoids a GCC warning.
12716 2012-04-09 Glenn Morris <rgm@gnu.org>
12718 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12719 preparation for dumping it with emacs. (Bug#4789)

12762 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12763 [!WINDOWSNT]: New macros.
12764 (init_libxml2_functions, libxml2_loaded_p): New functions.
12765 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12766 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12767 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12768 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12770 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12771 Call init_libxml2_functions before calling libxml2 functions.
12772 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12774 * emacs.c: Don't include libxml/parser.h.
12775 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12776 xmlCleanupParser directly.
12778 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12780 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12782 * indent.c (Fvertical_motion): If there is a display string at
12783 point, use it.vpos to compute how many lines to backtrack after
12784 move_it_to point. (Bug#11133)
12786 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12788 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12789 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12790 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12791 macros related to unification of CJK characters. For the details,
12792 see the discussion following the message here:
12793 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

12809 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12811 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12812 position we get to after a call to move_it_to fails the
12813 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12814 only if we wind up in a string from display property. (Bug#11063)
12816 * window.c (Fdelete_other_windows_internal): Invalidate the row
12817 and column information about mouse highlight, so that redisplay
12818 restores it after reallocating the glyph matrices. (Bug#7464)
12820 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12821 string comes from a `display' text property, use the buffer
12822 position of that property as if we actually saw that position in
12824 (move_it_by_lines): Remove the assertion that
12825 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12826 violated when there's a before-string at the beginning of a line.
12829 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12831 * xdisp.c (append_space_for_newline): If the default face was

12833 (extend_face_to_end_of_line): Use the remapped default face for
12834 extending the face to the end of the line.
12835 (display_line): Call extend_face_to_end_of_line when the default
12836 face was remapped. (Bug#11068)
12838 2012-03-29 Eli Zaretskii <eliz@gnu.org>

12846 2012-03-27 Glenn Morris <rgm@gnu.org>
12848 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12851 2012-03-26 Kenichi Handa <handa@m17n.org>
12853 * dispextern.h (struct glyph): Fix previous change. Change the
12854 bit length of glyphless.ch to 25 (Bug#11082).

12858 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12859 (command_loop_1): Use it; inhibit selection update for
12860 handle-select-window too (Bug#8996).
12862 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12864 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12866 2012-03-25 Kenichi Handa <handa@m17n.org>
12868 * dispextern.h (struct glyph): Change the bit length of
12869 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12871 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12873 * s/ms-w32.h (tzname): Include time.h before redirecting to
12874 _tzname. Fixes the MSVC build. (Bug#9960)
12876 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12878 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12881 * xterm.c (XTread_socket): Only modify handling_signal if
12882 !SYNC_INPUT. (Bug#11080)
12884 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12886 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12887 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12888 when fetching a multibyte character consumes more bytes than
12889 CHAR_BYTES returns, due to unification of CJK characters in
12890 string_char. (Bug#11073)
12892 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12894 * process.c (wait_reading_process_output): Handle pty disconnect
12895 by refraining from sending oneself a SIGCHLD (bug#10933).

12923 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12924 it fit in a valid range (Bug#11003).
12926 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12928 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12929 that is not from display property, accept the row as a "cursor
12930 row" if one of the string's character has a non-nil `cursor'
12931 property. Fixes cursor positioning when there are newlines in
12932 overlay strings, e.g. in icomplete.el. (Bug#11035)
12934 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12936 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12938 2012-03-12 Chong Yidong <cyd@gnu.org>
12940 * eval.c (inhibit_lisp_code): Rename from
12941 inhibit_window_configuration_change_hook; move from window.c.
12943 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12944 * window.c (run_window_configuration_change_hook)
12945 (syms_of_window): Callers changed.

12965 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12968 2012-03-03 Glenn Morris <rgm@gnu.org>
12970 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12972 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12974 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12975 position past the first glyph_row that ends at ZV. (Bug#10902)
12976 (redisplay_window, next_element_from_string): Fix typos in
12978 (redisplay_window): Pass to move_it_vertically the margin in
12979 pixels, not in screen lines.
12981 2012-03-02 Glenn Morris <rgm@gnu.org>
12983 * buffer.c (buffer-list-update-hook): Doc fix.
12985 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12987 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12988 push_it before setting up the iterator for the first overlay
12989 string, even if we have an empty string loaded.
12990 (next_overlay_string): If there's an empty string on the iterator
12991 stack, pop the stack. (Bug#10903)
12993 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12995 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12996 Suggested by Stefan Monnier in
12997 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12998 * alloc.c (widen_to_Lisp_Object): New static function.
12999 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13000 and widening them to Lisp_Objects. This would work even if
13001 USE_LSB_TAG is defined and wide integers are used, which might
13002 happen in a future version of Emacs.
13004 2012-02-25 Chong Yidong <cyd@gnu.org>
13006 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13009 * xselect.c (Fx_selection_exists_p): Doc fix.
13010 (x_clipboard_manager_save_all): Print an informative message
13011 before saving to clipboard manager.
13013 2012-02-24 Chong Yidong <cyd@gnu.org>
13015 * keyboard.c (process_special_events): Handle all X selection
13016 requests in kbd_buffer, not just the next one (Bug#8869).
13018 2012-02-23 Chong Yidong <cyd@gnu.org>
13020 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13021 call when setting menu-bar-lines and tool-bar-lines parameters.
13022 (unwind_create_frame_1): New helper function.
13024 * window.c (inhibit_window_configuration_change_hook): New var.

13035 * fileio.c (Vfile_name_handler_alist): Doc fix.
13037 * buffer.c (Fget_file_buffer): Protect against invalid file
13038 handler return value.
13040 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13042 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13043 when computing $valmask.
13045 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13046 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13047 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13048 It's useless in that case, and it can cause problems on hosts
13049 that allocate halves of EMACS_INT values separately.
13050 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13051 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13052 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13053 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13054 it avoids undefined behavior on hosts where shifting right by more
13055 than the word width has undefined behavior.
13057 2012-02-19 Chong Yidong <cyd@gnu.org>
13059 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13060 (Funhandled_file_name_directory, Ffile_name_as_directory)
13061 (Fdirectory_file_name, Fexpand_file_name)
13062 (Fsubstitute_in_file_name): Protect against invalid file handler
13063 return values (Bug#10845).
13065 2012-02-18 Eli Zaretskii <eliz@gnu.org>

13079 2012-02-15 Chong Yidong <cyd@gnu.org>
13081 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13082 marked as special. Also, starting docstrings with * is obsolete.

13097 2012-02-12 Chong Yidong <cyd@gnu.org>
13099 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13100 as that creates a dangerous corner case.
13102 * window.c (Fdelete_window_internal): Invalidate the mouse
13103 highlight (Bug#9904).
13105 2012-02-12 Glenn Morris <rgm@gnu.org>

13110 * nsselect.m (Fx_own_selection_internal)
13111 (Fx_disown_selection_internal, Fx_selection_exists_p)
13112 (Fx_selection_owner_p, Fx_get_selection_internal):
13113 Sync docs and argument specs with the xselect.c versions.
13115 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

13135 2012-02-07 Chong Yidong <cyd@gnu.org>
13137 * buffer.c (Fbuffer_local_variables)
13138 (buffer_lisp_local_variables): Handle unbound vars correctly;
13139 don't let Qunbound leak into Lisp.
13141 2012-02-07 Glenn Morris <rgm@gnu.org>
13143 * image.c (Fimagemagick_types): Doc fix.
13145 * image.c (imagemagick-render-type): Change it from a lisp object
13146 to an integer. Move the doc here from the lisp manual.

13176 before BEGV. (Bug#10696)
13178 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13180 Handle overflow when computing char display width (Bug#9496).
13181 * character.c (char_width): Return EMACS_INT, not int.
13182 (char_width, c_string_width): Check for overflow when
13183 computing the width; this is possible now that individual
13184 characters can have unbounded width. Problem introduced
13185 by merge from Emacs 23 on 2012-01-19.
13187 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13209 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13211 (x_produce_glyphs): If the component of a composition is a null
13212 string, set it->pixel_width to 1 to avoid zero-width glyph.
13214 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13216 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13217 first 2 arguments are identical. This makes inserting large
13218 output from a subprocess an order of magnitude faster on
13219 MS-Windows, where all sbrk'ed memory is always contiguous.
13221 2012-01-31 Glenn Morris <rgm@gnu.org>

13304 2012-01-11 Glenn Morris <rgm@gnu.org>
13306 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

13311 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
13313 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
13314 Update template values to be closer to their typical values these days.
13316 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13318 * xdisp.c (rows_from_pos_range): Accept additional argument
13319 DISP_STRING, and accept any glyph in a row whose object is that
13320 string as eligible for mouse highlight. Fixes mouse highlight of

13834 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13835 Otherwise, valgrind does not work on some platforms.
13836 Problem reported by Andreas Schwab in
13837 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13838 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13839 is set, removing the need for VIRT_ADDRESS_VARIES.
13840 (PURE_P): Use a more-efficient implementation that needs just one
13841 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13842 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13843 to 4 (xorl, subq, cmpq, setbe).
13844 * alloc.c (pure): Always extern now, since that's the
13845 VIRT_ADDR_VARIES behavior.
13846 (PURE_POINTER_P): Use a single comparison, not two, for
13847 consistency with the new puresize.h.
13848 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13849 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13857 behave as if the cursor position were at the window margin.
13859 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13860 and the cursor position is out of bounds, behave as if the cursor
13861 position were at the window margin. (Bug#10075)
13863 2011-11-18 Chong Yidong <cyd@gnu.org>
13865 * window.c (Fwindow_combination_limit): Make first argument

13887 compute_line_metrics.
13888 (compute_line_metrics): Call row_hash, instead of computing the
13891 * dispnew.c (verify_row_hash): Call row_hash for computing the
13892 hash code of a row, instead of duplicating code from xdisp.c.
13894 * dispextern.h (row_hash): Add prototype.
13896 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13932 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13934 * xdisp.c (display_line): Move the call to
13935 highlight_trailing_whitespace before the call to
13936 compute_line_metrics, since the latter needs to see the final
13937 faces of all the glyphs to compute ROW's hash value.
13938 Fixes assertion violations in row_equal_p. (Bug#10035)
13940 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13942 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

13947 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13948 with user-defined heap size. Bump the default size of the temacs
13949 heap to 27MB, to avoid memory warning when running temacs.

13952 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13953 current_matrix and desired_matrix. (Bug#9990)
13954 (verify_row_hash) [XASSERTS]: New function.

14001 Avoid some portability problems by eschewing 'extern inline' functions.
14002 The trivial performance wins aren't worth the portability hassles; see
14003 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14005 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14081 Otherwise, these inline functions do not conform to C99 and
14082 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14083 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14084 * intervals.c (adjust_intervals_for_insertion)

14088 (offset_intervals): Rewrite using the old contents of
14089 static_offset_intervals. The old version didn't conform to C99

14247 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14249 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14251 * xterm.c: Declare x_handle_net_wm_state to return int.
14252 (handle_one_xevent): Check if we are iconified but don't have
14253 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14254 (get_current_wm_state): Return non-zero if not hidden,
14255 check for _NET_WM_STATE_HIDDEN (Bug#9893).
14256 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
14257 (x_handle_net_wm_state): Return what get_current_wm_state returns.
14258 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
14260 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14262 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14263 so that this new function doesn't get optimized away by a
14264 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14266 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14268 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14270 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14272 Fix the `xbytecode' command.
14273 * .gdbinit (xprintbytestr): New command.
14274 (xwhichsymbols): Rename from `which'; all callers changed.
14275 (xbytecode): Print the byte-code string as well.
14277 2011-10-29 Kim Storm <storm@cua.dk>
14279 * alloc.c (which_symbols): New function.
14281 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14283 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14286 2011-10-29 Glenn Morris <rgm@gnu.org>
14288 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14289 Not clear what it was for, and it causes various bugs. (Bug#9839)
14291 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14293 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14294 possible random value that matches one of those tested as
14295 condition to clear the mouse face.
14297 2011-10-28 Chong Yidong <cyd@gnu.org>
14299 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14301 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14303 * window.c (make_window): Initialize phys_cursor_on_p.
14305 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14307 * lisp.h (struct Lisp_Symbol): Update comments.
14309 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14311 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14313 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14315 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14316 <oslsachem@gmail.com> for helping to debug this.
14318 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14319 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14320 (g_b_init_get_glyph_outline_w): New static variables.
14321 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14322 (GetGlyphOutlineW_Proc): New typedefs.
14323 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14324 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14326 (w32font_open_internal, compute_metrics):
14327 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14328 instead of calling the "wide" APIs directly.
14330 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14332 * w32.h (syms_of_w32font): Add prototype.
14334 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14336 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14337 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14338 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14339 (Fmove_to_window_line): Doc fix.
14341 2011-10-27 Chong Yidong <cyd@gnu.org>
14343 * process.c (make_process): Set gnutls_state to NULL.
14345 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14346 non-NULL, regardless of GNUTLS_INITSTAGE.
14347 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14348 an error. Set process slots as soon as we allocate them.
14350 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14352 2011-10-27 Chong Yidong <cyd@gnu.org>
14354 * gnutls.c (emacs_gnutls_deinit): New function.
14355 Deallocate credentials structures as well as calling gnutls_deinit.
14356 (Fgnutls_deinit, Fgnutls_boot): Use it.
14358 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14359 (deactivate_process): Call emacs_gnutls_deinit.
14361 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14363 * image.c (x_create_x_image_and_pixmap):
14364 * w32.c (sys_rename, w32_delayed_load):
14365 * w32font.c (fill_in_logfont):
14366 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14368 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14370 * w32fns.c (w32_default_color_map): New function,
14371 extracted from Fw32_default_color_map.
14372 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14374 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14376 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14378 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14380 * keyboard.c (test_undefined): New function (bug#9751).
14381 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14383 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14385 * sysdep.c (init_sys_modes): Fix the check for the controlling
14386 terminal (Bug#6649).
14388 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14390 * dispextern.h (struct bidi_it): New member next_en_type.
14392 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14393 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14394 current character, check also for next_en_type being WEAK_EN.
14395 (bidi_resolve_weak): Don't enter the expensive loop if the current
14396 position is before next_en_pos. Record the bidi type of the first
14397 non-ET, non-BN character we find, in addition to its position.
14398 (bidi_level_of_next_char): Invalidate next_en_type when
14399 next_en_pos is over-stepped.
14401 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14403 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14404 * editfns.c: Rewrite current-time-zone so that it invokes
14405 the equivalent of (format-time-string "%Z") to get the time zone name.
14406 This fixes a bug when the time zone name contains characters that
14407 need converting from the system time locale to Emacs internal format.
14408 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14409 that patch fixed format-time-string to do the conversion, but
14410 I forgot to fix current-time-zone.
14411 (format_time_string): New function, containing most of
14412 what Fformat_time_string used to contain.
14413 (Fformat_time_string): Rewrite in terms of format_time_string.
14414 This doesn't change this function's behavior.
14415 (current-time-zone): Rewrite to use format_time_string.
14416 This fixes the bug reported by Michael Schierl in
14417 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14418 Jason Rumney's 2007-06-07 change worked around this bug, but
14420 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14422 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14424 * xdisp.c (start_display): If the character at POS is displayed
14425 via a display vector, reset IT->current.dpvec_index to zero.
14426 (try_window_reusing_current_matrix): If a line ends in a display
14427 vector or the next line starts in a display vector, continue
14428 redrawing the window even though the character position of
14429 start_row was reached.
14432 2011-10-18 Chong Yidong <cyd@gnu.org>
14434 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14435 with nobreak-char-display too.
14437 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14439 Fix part 3 of bug#9771.
14440 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14441 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14442 non-neutral characters if the current character is a paragraph
14443 separator (a.k.a. Newline). This avoids running the same
14444 expensive loop twice, once when we consume the preceding newline
14445 and the other time when the line actually needs to be displayed.
14446 Avoid the loop when we see neutrals on the base embedding level
14447 following a character whose directionality is the same as the
14448 paragraph's. This avoids running the expensive loop when a line
14449 ends in a long sequence of neutrals, like control characters.
14450 Add assertion against STRONG_AL type. Slightly rearrange code
14451 that determines the type of a neutral given the first non-neutral
14453 (bidi_level_of_next_char): Set next_en_pos to zero when
14454 invalidating its info.
14456 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14458 * xdisp.c (push_display_prop): Determine whether to record string
14459 or buffer position by IT->string, not by IT->method. Allow
14460 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14461 (move_it_vertically_backward): Don't look for character position
14462 immediately after the newline when in a continuation line.
14465 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14467 * window.c (coordinates_in_window): Rewrite and delabelize
14468 vertical border check. (Bug#5357) (Bug#9618)
14470 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14472 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14473 errors in XSetWindowBorder (bug#9310).
14475 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14477 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14478 avoid crash when xmalloc overrun checking is enabled.
14480 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14482 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14483 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14484 cursor motion with <left> and <right> arrow keys.
14486 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14487 some callers set that themselves.
14489 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14491 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14492 display string and the previous row comes from the same string and
14493 is empty. (Bug#9739) (Bug#9738)
14495 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14497 * doc.c (get_doc_string): Encode file name (bug#9735).
14499 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14501 * bidi.c (bidi_level_of_next_char):
14502 * xdisp.c (get_visually_first_element): Remove old incorrect
14503 comments regarding the Unicode Line Separator character.
14505 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14507 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14509 * alloc.c (Fgc_status): Do not access beyond zombies array
14510 boundary if nzombies > MAX_ZOMBIES.
14511 * alloc.c (dump_zombies): Add missing format specifier.
14513 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14515 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14516 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14518 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14519 Some packages use them to denote characters with modifiers.
14521 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14523 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14524 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14525 matching a pp-number. Rename parameter var to var1.
14527 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14529 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14531 2011-10-08 Glenn Morris <rgm@gnu.org>
14533 * callint.c (Fcall_interactively): Give a more explicit error for the
14534 'c' case with a non-character input. (Bug#8479)
14536 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14538 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14540 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14541 lines that are hscrolled on the left.
14543 * dispnew.c (buffer_posn_from_coords): Account for a possible
14544 presence of header-line. (Bug#4426)
14546 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14548 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14549 Don't advertise functionality which we discourage or doesn't work.
14551 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14553 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14554 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14555 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14556 this makes Emacs dump core during garbage collection on rare
14557 occasions. sizeof is obviously inferior to offsetof here, so
14558 stick with offsetof.
14559 (GC_POINTER_ALIGNMENT): New macro.
14560 (mark_memory): Omit 3rd (offset) arg; caller changed.
14561 Don't assume EMACS_INT alignment is the same as pointer alignment.
14563 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14565 * keyboard.c (read_key_sequence_remapped): New var.
14566 (read_key_sequence): Compute remapping in the right buffer.
14567 (command_loop_1): Use read_key_sequence's remapping directly.
14569 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14571 * dired.c (file_name_completion): Don't expand file name.
14572 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14573 before checking file name handler.
14575 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14576 they've been requested explicitly (bug#9591).
14578 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14580 * keymap.c (Fsingle_key_description): Use make_specified_string
14581 instead of build_string to build string from push_key_description.
14584 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14586 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14587 This fixes a Y2038 bug on 64-bit hosts.
14588 * buffer.c (reset_buffer):
14589 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14590 (Fclear_buffer_auto_save_failure):
14591 Use 0, not -1, to represent an unset failure time, since time_t
14592 might not be signed.
14594 Remove dependency on glibc malloc internals.
14595 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14596 Move back here from lisp.h, but with their new implementations.
14597 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14598 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14599 * charset.c (charset_table_init): New static var.
14600 (syms_of_charset): Use it instead of xmalloc. This removes a
14601 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14602 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14603 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14604 Move back to alloc.c.
14605 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14606 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14608 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14610 * nsterm.m (windowDidResize): Call x_set_window_size only when
14611 ns_in_resize is true. Otherwise set pixelwidth/height and
14612 call change_frame_size (Bug#9628).
14614 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14616 Port --enable-checking=all to Fedora 14 x86-64.
14617 * charset.c (syms_of_charset): Also account for glibc malloc's
14618 internal overhead when calculating the initial malloc maximum.
14620 Port --enable-checking=all to Fedora 14 x86.
14621 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14623 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14624 (overrun_check_realloc, overrun_check_free):
14625 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14626 That way, xmalloc returns a properly-aligned pointer even if
14627 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14628 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14629 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14630 into account when calculating the initial malloc maximum.
14631 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14632 Move here from alloc.c, so that charset.c can use it too.
14633 Properly align; the old code wasn't right for common 32-bit hosts
14634 when configured with --enable-checking=all.
14635 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14636 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14638 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14640 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14643 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14645 * xdisp.c (compute_display_string_end): If there's no display
14646 string at CHARPOS, return -1.
14648 * bidi.c (bidi_fetch_char): When compute_display_string_end
14649 returns a negative value, treat the character as a normal
14650 character not covered by a display string. (Bug#9624)
14652 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14654 * lread.c (Fread_from_string): Fix typo in docstring.
14656 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14658 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14659 newline, reseat the iterator instead of bidi-iterating there one
14660 character at a time. (Bug#9610)
14661 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14662 TO_CHARPOS if the bidi iterator is at base embedding level.
14664 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14666 * lread.c (readevalloop): Use correct code for NBSP.
14667 (read1): Likewise. (Bug#9608)
14669 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14671 * dbusbind.c (Fdbus_register_signal): When service is not
14672 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14674 2011-09-25 Glenn Morris <rgm@gnu.org>
14676 * buffer.c (truncate-lines): Doc fix.
14678 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14680 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14681 (Fset_window_next_buffers): Doc fix.
14683 2011-09-24 Glenn Morris <rgm@gnu.org>
14685 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14687 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14689 Fix minor problems found by static checking.
14690 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14691 * indent.c (Fvertical_motion): Fix == vs = typo.
14693 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14695 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14696 Default value is now t. Doc fix.
14698 * indent.c (Fvertical_motion): Compute and apply the overshoot
14699 logic when moving up, not only when moving down. Fix the
14700 confusing name and values of the it_overshoot_expected variable;
14701 logic changes accordingly. (Bug#9254) (Bug#9549)
14703 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14704 CHARPOS is covered by a display string which includes newlines.
14705 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14706 is covered by a display string with embedded newlines.
14708 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14710 * dbusbind.c (Fdbus_register_signal): Add match rule to
14711 Vdbus_registered_objects_table. (Bug#9581)
14712 (Fdbus_register_method, Vdbus_registered_objects_table):
14715 2011-09-24 Jim Meyering <meyering@redhat.com>
14717 do not ignore write error for any output size
14718 The previous change was incomplete.
14719 While it makes emacs --batch detect the vast majority of stdout
14720 write failures, errors were still ignored whenever the output size is
14721 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14722 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14723 && echo FAIL: ignored write error
14724 FAIL: ignored write error
14725 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14726 && echo FAIL: ignored write error
14727 FAIL: ignored write error
14728 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14730 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14732 * emacs.c (Fkill_emacs): In noninteractive mode exit
14733 non-successfully if a write error occurred on stdout. (Bug#9574)
14735 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14737 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14740 * dispextern.h (struct it): Update the comment documenting what
14743 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14745 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14746 a display string, extend search for cursor position to end of row.
14747 (find_row_edges): If the row ends in a newline from a display
14748 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14749 Handle the case of a display string with multiple newlines.
14750 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14751 non-empty line. Fixes confusing cursor motion with arrow keys at
14752 the beginning of a line that starts with whitespace.
14754 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14756 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14759 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14761 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14762 boolean (Bug#9154).
14764 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14766 * xdisp.c (display_line): Record maximum and minimum buffer
14767 positions even if no glyphs were produced (e.g., by a zero-width
14768 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14769 buffer positions that will be removed from the glyph row because
14771 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14772 column is beyond frame width: don't subtract 1 "pixel" when
14773 computing width of the stretch.
14774 (reseat_at_next_visible_line_start): Undo the change made on
14775 2011-09-17 that saved paragraph information and restored it after
14776 the call to `reseat'. (Bug#9545)
14778 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14780 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14781 and turn window cursor on if cleared (Bug#9415).
14783 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14785 * search.c (boyer_moore): Take unibyte characters from pattern
14786 literally. (Bug#9458)
14788 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14790 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14792 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14794 Fix minor problem found by static checking.

14796 initialized, to pacify gcc -Wuninitialized.
14798 * fileio.c: Report proper errno when syscall falls.
14799 (Finsert_file_contents): Save and restore errno,
14800 so that report_file_error outputs the correct diagnostic.
14801 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14803 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14805 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14807 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14809 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14810 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14812 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14814 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14815 about the current paragraph and restore it after the call to reseat.
14817 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14818 (bidi_find_paragraph_start): Search back for paragraph beginning
14819 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14820 (bidi_move_to_visually_next): Only trigger paragraph-related
14821 computations when the last character is a newline or at EOB, not
14822 just any NEUTRAL_B. (Bug#9470)
14824 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14825 truncated lines if point is covered by a display string. (Bug#9524)
14827 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14829 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14830 (cons_to_x_long): New function.
14831 (lisp_data_to_selection_data): Use it. Correct the test for
14832 short-versus-long data; it was negated. Break out of vector
14833 loop, for efficiency, when a long datum is discovered.
14835 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14837 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14839 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14841 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14842 GCC PR/17406) by declaring this function with external scope.
14844 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14846 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14847 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14849 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14851 * editfns.c (Fformat): Correctly handle text properties on "%%".

14860 (fill_composite_glyph_string): Add comments about special meaning
14861 of TAB characters in a composition.
14863 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14865 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14866 This occurs when processing a multibyte format.
14867 Problem reported by Wolfgang Jenker.
14869 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14871 * xdisp.c (try_cursor_movement): Only check for exact match if
14872 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14874 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14876 Remove unused external symbols.
14877 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14878 * xdisp.c (calc_pixel_width_or_height): Now static.
14879 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14880 * indent.c (check_display_width):
14881 * w32term.c: Fix comment to match code.
14882 * xterm.c, xterm.h (x_catching_errors): Remove.
14884 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14886 * xselect.c: Use signed conversions more consistently (Bug#9498).
14887 (selection_data_to_lisp_data): Assume incoming selection data are
14888 signed integers, not unsigned. This is to be consistent with
14889 outgoing selection data, which was modified to use signed integers
14890 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14891 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14892 expects long, not unsigned long.
14894 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14896 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14897 computation of loop end. Reported by Johan Bockgård
14900 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14902 * frame.c (Fother_visible_frames_p): Function deleted.
14904 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14906 * indent.c (compute_motion): Process display vector front to back
14907 rather than the other way around. (Bug#2496)
14909 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14911 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14913 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14915 * minibuf.c (Fread_from_minibuffer): Doc fix.
14917 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14919 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14920 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14922 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14924 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14925 value for non-existent files.
14927 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14929 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14930 set its "size" to -1. This will set the modtime_size field of
14931 the corresponding buffer to -1, which is what
14932 verify-visited-file-modtime expects for files that do not exist.
14935 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14937 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14939 * lisp.h: ... from here. push_key_description is no longer
14940 defined in keyboard.c, so its declaration should not be in
14941 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14942 logically belongs with push_key_description.
14944 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14946 * buffer.h: Include <sys/types.h> instead of <time.h>.
14947 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14948 Problem reported by Herbert J. Skuhra.
14950 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14952 * xml.c (parse_region): Make the parsing work for
14953 non-comment-starting XML files again (bug#9144).
14955 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14957 * image.c (gif_load): Fix calculation of bottom and right corner.
14960 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14962 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14963 redisplay in small windows.
14965 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14967 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14969 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14971 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14972 Operate on live windows only.
14974 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14976 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14978 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14980 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14981 only under bidi iteration.
14983 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14985 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14987 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14989 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14990 Without this fix, the command to link temacs failed due to an
14991 undefined symbol __builtin_isnan. This is because
14992 /usr/include/iso/math_c99.h #defines isnan(x) to
14993 __builtin_isnan(x), but the bundled gcc, which identifies itself
14994 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14996 * floatfns.c (isnan): #undef, and then #define to a clone of
14998 (Fisnan): Always define, since it's always available now.
14999 (syms_of_floatfns): Always define isnan at the Lisp level.
15001 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15003 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15005 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15007 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15008 The previous code assumed that file offsets (off_t values) fit in
15009 EMACS_INT variables, which is not true on typical 32-bit hosts.
15010 The code messed up by falsely reporting buffer overflow in cases
15011 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15012 when "big" contains more than 2**29 bytes, even though this
15013 inserts just one byte and does not overflow the buffer.
15014 (Finsert_file_contents): Store file offsets as off_t
15015 values, not as EMACS_INT values. Check for overflow when
15016 converting between EMACS_INT and off_t. When checking for
15017 buffer overflow or for overlap, take the offsets into account.
15018 Don't use EMACS_INT for small values where int suffices.
15019 When checking for overlap, fix a typo: ZV was used where
15020 ZV_BYTE was intended.
15021 (Fwrite_region): Don't assume off_t fits into 'long'.
15022 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15024 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15026 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15028 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15030 sprintf-related integer and memory overflow issues (Bug#9412).
15032 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15033 (esprintf, exprintf, evxprintf): New functions.
15034 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15035 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15036 (modify_event_symbol): Do not assume that the length of
15037 name_alist_or_stem is safe to alloca and fits in int.
15038 (Fexecute_extended_command): Likewise for function name and binding.
15039 (Frecursion_depth): Wrap around reliably on integer overflow.
15040 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15041 since some callers pass EMACS_INT values.
15042 (Fsingle_key_description): Don't crash if symbol name contains more
15043 than MAX_ALLOCA bytes.
15044 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15045 (get_minibuffer): Arg is now EMACS_INT, not int.
15046 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15047 (esprintf, exprintf, evxprintf): New decls.
15048 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15050 * dbusbind.c (signature_cat): New function.
15051 (xd_signature, Fdbus_register_signal):
15052 Do not overrun buffer; instead, report string overflow.
15054 * dispnew.c (add_window_display_history): Don't overrun buffer.
15055 Truncate instead; this is OK since it's just a log.
15057 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15058 even if the time zone offset is outlandishly large.
15059 Don't mishandle offset == INT_MIN.
15061 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15062 when creating daemon; the previous buffer-overflow check was incorrect.
15064 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15065 which has the guts of the old verror function.
15067 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15068 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15070 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15071 (font_unparse_xlfd): Don't blindly alloca long strings.
15072 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15073 fits in int, when using sprintf. Use single snprintf to count
15074 length of string rather than counting it via multiple sprintfs;
15075 that's simpler and more reliable.
15076 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15077 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15078 sprintf, in case result does not fit in int.
15080 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15081 (fontset_from_font): Print it.
15083 * frame.c (tty_frame_count): Now printmax_t, not int.
15084 (make_terminal_frame, set_term_frame_name): Print it.
15085 (x_report_frame_params): In X, window IDs are unsigned long,
15086 not signed long, so print them as unsigned.
15087 (validate_x_resource_name): Check for implausibly long names,
15088 and don't assume name length fits in 'int'.
15089 (x_get_resource_string): Don't blindly alloca invocation name;
15090 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15093 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15094 (xg_check_special_colors, xg_set_geometry):
15095 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15097 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15098 Use esprintf, not sprintf, in case result does not fit in int.
15100 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15101 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15102 it as a large positive number.
15103 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15104 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15106 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15107 in case result does not fit in int.
15109 * print.c (float_to_string): Detect width overflow more reliably.
15110 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15111 buffer overrun. Don't assume list length fits in 'int'. Treat
15112 print length of 0 as 0, not as infinity; to be consistent with other
15113 uses of print length in this function. Don't overflow print length
15114 index. Don't assume hash table size fits in 'long', or that
15115 vectorlike size fits in 'unsigned long'.
15117 * process.c (make_process): Use printmax_t, not int, to format
15118 process-name gensyms.
15120 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15122 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15123 to avoid potential buffer overrun.
15125 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15126 if X resource line is longer than 512 bytes.
15128 * xfns.c (x_window): Make sprintf buffer a bit bigger
15129 to avoid potential buffer overrun.
15131 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15133 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15135 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15137 Integer overflow fixes for scrolling, etc.
15138 Without these, Emacs silently mishandles large integers sometimes.
15139 For example, "C-u 4294967297 M-x recenter" was treated as if
15140 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15142 * xdisp.c (try_window_id): Check Emacs fixnum range before
15143 converting to 'int'.
15145 * window.c (window_scroll_line_based, Frecenter):
15146 Check that an Emacs fixnum is in range before assigning it to 'int'.
15147 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15148 values converted from Emacs fixnums.
15149 (Frecenter): Don't wrap around a line count if it is out of 'int'
15150 range; instead, treat it as an extreme value.
15151 (Fset_window_configuration, compare_window_configurations):
15152 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15154 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15155 that can exceed INT_MAX. Check that EMACS_INT value is in range
15156 before assigning it to the (possibly-narrower) index.
15157 (match_limit): Don't assume that a fixnum can fit in 'int'.
15159 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15162 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15163 (Fvertical_motion): Don't wrap around LINES values that don't fit
15164 in 'int'. Instead, treat them as extreme values. This is good
15165 enough for windows, which can't have more than INT_MAX lines anyway.
15167 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15169 * Require libxml/parser.h to avoid compilation warning.
15171 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15173 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15174 since this reportedly can destroy thread storage.
15176 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15178 * syntax.c (find_defun_start): Update all cache variables if
15179 exiting early (Bug#9401).
15181 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15183 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15185 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15186 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15187 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15189 * term.c (tty_append_glyph): New function.
15190 (produce_stretch_glyph): Static function and its prototype deleted.
15192 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15195 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15197 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15198 when checking :margin (Bug#9390).
15199 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15200 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15201 so that the name doesn't mislead. All uses changed.
15203 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15205 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

15210 * xdisp.c (move_it_to): Don't bail out early when reaching
15211 position beyond to_charpos, if we are scanning backwards.
15212 (move_it_vertically_backward): When DY == 0, make sure we get to
15213 the first character in the line after the newline.
15215 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15217 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15218 (ccl_driver): Do not generate an out-of-range pointer.
15219 (Fccl_execute_on_string): Remove unnecessary check for
15220 integer overflow, noted by Stefan Monnier in
15221 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15222 Remove a FIXME that didn't need fixing.
15223 Simplify the newly-introduced buffer reallocation code.
15225 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15227 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15229 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15231 Integer and memory overflow issues (Bug#9196).
15233 * doc.c (get_doc_string): Rework so that
15234 get_doc_string_buffer_size is the actual buffer size, rather than
15235 being 1 less than the actual buffer size; this makes xpalloc more
15238 * image.c (x_allocate_bitmap_record, cache_image):
15239 * xselect.c (Fx_register_dnd_atom):
15240 Simplify previous changes by using xpalloc.
15242 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15243 since either will do and ptrdiff_t is convenient with xpalloc.

15246 (struct charset_sort_data.priority): Now ptrdiff_t.
15247 (charset_compare): Don't overflow if priorities differ greatly.
15248 (Fsort_charsets): Don't assume list length fits in int.
15249 Check for size-calculation overflow when allocating sort data.
15250 (syms_of_charset): Allocate an initial charset table that is
15251 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15253 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15255 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15256 The actual value is always <= INT_MAX, and leaving it unsigned made
15257 overflow checking harder.
15259 * dispextern.h (struct glyph_matrix.rows_allocated)
15260 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15261 with xpalloc. The values are still always <= INT_MAX.
15263 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15265 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15266 (SAFE_NALLOCA): New macro.

15269 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15270 (set_cache_region, invalidate_region_cache)
15271 (revalidate_region_cache, know_region_cache, region_cache_forward)
15272 (region_cache_backward, pp_cache):
15273 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15274 so that ptrdiff_t * can be passed to xpalloc.
15275 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15276 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15277 (pp_cache): Don't assume cache_len fits in int.
15278 * region-cache.h: Adjust extern decls to match.
15280 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15281 EMACS_INT, since either will do, for xpalloc.
15283 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15284 (xnmalloc, xnrealloc, xpalloc): New functions.
15286 * bidi.c (bidi_shelve_header_size): New constant.
15287 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15288 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15290 * bidi.c (bidi_cache_shrink):
15291 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15293 Don't update size of array until after memory allocation succeeds,
15294 because xmalloc/xrealloc may not return.
15295 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15296 now that we have proper integer overflow checking.
15297 (record_overlay_string, overlay_strings): Catch overflows when
15298 calculating size of overlay_str_buf.
15300 * callproc.c (Fcall_process): Check for size overflow when
15301 calculating size of args2.
15302 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15303 Normally we prefer signed values, but sticking with ptrdiff_t would
15304 require adding more-complicated checks.
15306 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15307 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15308 Redo buffer-overflow calculations to avoid integer overflow.
15309 Add a FIXME comment where memory seems to be over-allocated.
15311 * character.c (Fstring): Check for size-calculation overflow.
15313 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15314 unnecessary integer overflow. Check for size overflow.
15315 (encode_coding_object): Don't update size until xmalloc succeeds.
15317 * composite.c (get_composition_id): Check for overflow in glyph
15318 length calculations.
15320 Integer and memory overflow fixes for display code.
15321 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15322 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

15335 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15336 (get_doc_string): Check for size calculation overflow.
15337 Don't update size until allocation succeeds.
15338 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not

15344 (message_length): Now ptrdiff_t, not int.
15345 (Fmessage_box): Don't update size until allocation succeeds.
15346 Don't assume message length fits in int.
15347 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15349 * emacs.c (main): Do not reallocate argv, since there is a null at
15350 the end that can be overwritten, and this way there's no need to
15351 worry about size-calculation overflow.
15352 (sort_args): Check for size-calculation overflow.
15354 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15356 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15358 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15359 (x_set_scroll_bar_width, x_figure_window_size):
15360 Check for integer overflow.
15361 (x_set_alpha): Do not assume XINT fits in int.
15363 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15364 This is for the members text_lines, text_cols, total_lines, total_cols,
15365 where the system imposes an 'int' limit.
15367 * fringe.c (Fdefine_fringe_bitmap):
15368 Don't update size until alloc works.
15370 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15371 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15373 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15374 Check for size-calculation overflow.
15375 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15376 do, as we prefer signed integers.
15377 (id_to_widget.max_size, id_to_widget.used)
15378 (xg_store_widget_in_map, xg_remove_widget_from_map)
15379 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15380 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15381 Use and return ptrdiff_t, not int.
15382 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15383 * gtkutil.h: Change prototypes to match the above.
15385 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15386 are duplicate now that they've been promoted to lisp.h.
15387 (x_allocate_bitmap_record, x_alloc_image_color)
15388 (make_image_cache, cache_image, xpm_load):
15389 Don't update size until alloc is done.

15400 Use ptrdiff_t, not int, to count maps.
15401 (read_char_minibuf_menu_prompt): Check for overflow in size
15402 calculations. Don't update size until allocation succeeds.
15403 Redo calculations to avoid overflow.
15404 * keyboard.h: Change prototypes to match the above.
15406 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

15432 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15433 for command line length. Do not attempt to address one before the
15434 beginning of an array, as that's not portable.
15436 * term.c (max_frame_lines): Remove; unused.
15437 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15439 (encode_terminal_code, calculate_costs): Check for size

15462 Use ptrdiff_t, not int, for sizes.
15463 (Finternal_make_lisp_face, cache_face):
15464 Check for size calculation overflow.
15465 (cache_face): Treat size calculation overflows as if they were

15469 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15470 sizes, since they can exceed INT_MAX in size. Check for size

15474 (xg_select): Check for size calculation overflow.
15475 Don't update size until alloc done.
15477 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15478 as sprintf is limited to int lengths.
15480 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15481 (X_LONG_MIN): New macros.
15482 Use them to make the following changes clearer.
15483 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15484 This change doesn't affect the value now, but it may help remind
15485 future maintainers not to raise the value too much later.
15486 (SELECTION_QUANTUM): Remove, replacing with ...
15487 (selection_quantum): ... new function, which avoids overflow.
15489 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15490 assumption that selection length fits in 'int'.

15503 (lisp_data_to_selection_data, x_property_data_to_lisp):

15507 Don't store size until memory allocation succeeds.
15508 (x_get_window_property): Plug memory leak on memory exhaustion.
15509 Don't double-block input; malloc is safe here. Don't assume 2**34
15510 - 4 fits in unsigned long. Add an xassert to check
15511 XGetWindowProperty overflow. Be more careful about overflow
15512 calculations, and distinguish size from memory overflow better.
15513 (receive_incremental_selection): When tracing, don't assume
15514 unsigned int is less than INT_MAX.
15515 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15516 harmful) conversions of unsigned short to int.
15517 (lisp_data_to_selection_data): Don't assume that integers
15518 in the range -65535 through -1 fit in an X unsigned short.
15519 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15520 result parameters unless successful. Rely on cons_to_unsigned
15521 to report problems with elements; the old code wasn't right anyway.
15522 (x_check_property_data): Check for int overflow; we cannot use
15523 a wider type due to X limits.
15524 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

15556 * lisp.h (hash_lookup, hash_put):
15557 * minibuf.c (Ftest_completion):
15558 Use ptrdiff_t for hash table indexes, not int (which is too
15559 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15560 32-bit --with-wide-int hosts).
15562 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15563 Add a FIXME comment about memory leaks.
15564 (syms_of_charset): Don't assume xmalloc returns.

15571 with outlandish widths.
15572 * character.h (sanitize_tab_width): Rename from sanitize_width,
15573 now that we have two such functions. All uses changed.

15587 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15588 Remove unreachable code.
15589 (read_hex, load_charset_map_from_file): Check for integer overflow.
15591 * xterm.c: Don't go over XClientMessageEvent limit.
15592 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15593 (x_send_scroll_bar_event): Likewise. Check that the size does not
15594 exceed limits imposed by XClientMessageEvent, as well as the usual
15595 ptrdiff_t and size_t limits.
15597 * keyboard.c: Overflow, signedness and related fixes.
15598 (make_lispy_movement): Use same integer type in forward decl
15599 that is used in the definition.
15600 (read_key_sequence, keyremap_step):
15601 Change bufsize argument back to int, undoing my 2011-03-30 change.
15602 We prefer signed types, and int is wide enough here.
15603 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15604 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15605 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15606 length, not size_t. Use ptrdiff_t for index, not int.
15607 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15608 possibility of integer overflow.
15610 Overflow, signedness and related fixes for images.
15612 * dispextern.h (struct it.stack[0].u.image.image_id)
15613 (struct_it.image_id, struct image.id, struct image_cache.size)
15614 (struct image_cache.used, struct image_cache.ref_count):

15620 * xdisp.c (calc_pixel_width_or_height):
15621 * xfns.c (image_cache_refcount):
15622 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
15623 on typical 64-bit hosts.
15625 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15626 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

15629 when the callers expect that.
15630 (image_ascent): Redo ascent calculation to avoid int overflow.
15631 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15632 (lookup_image): Remove unnecessary tests.
15633 (xbm_image_p): Locals are now of int, not EMACS_INT,
15634 since parse_image_check makes sure they fit into int.
15635 (png_load, gif_load, svg_load_image):
15636 Prefer int to unsigned where either will do.
15637 (tiff_handler): New function, combining the cores of the
15638 old tiff_error_handler and tiff_warning_handler.
15639 This function is rewritten to use vsnprintf and thereby avoid
15640 stack buffer overflows. It uses only the features of vsnprintf
15641 that are common to both POSIX and native Microsoft.
15642 (tiff_error_handler, tiff_warning_handler): Use it.
15643 (tiff_load, gif_load, imagemagick_load_image):
15644 Don't assume :index value fits in 'int'.
15645 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15646 (imagemagick_load_image): Check that crop parameters fit into
15647 the integer types that MagickCropImage accepts. Don't assume
15648 Vimagemagick_render_type has a nonnegative value. Don't assume
15649 size_t fits in 'long'.
15650 (gs_load): Use printmax_t to print the widest integers possible.
15651 Check for integer overflow when computing image height and width.
15653 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15655 * xdisp.c (redisplay_window): Don't force window start if point

15663 handle_single_display_spec, not just 1 or zero.
15664 (handle_single_display_spec): If the display spec is of the form
15665 `(space ...)', and specifies display in the text area, return 2
15667 (try_cursor_movement): Check for the need to scroll more
15668 accurately, and prefer exact match for point under bidi.
15669 Don't advance `row' beyond the last row of the window.
15671 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15672 into disp_prop; all users changed.
15674 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15675 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15676 for the text covered by the display property.

15686 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15687 buffers, return left-to-right.
15688 (set_cursor_from_row): Consider candidate row a win if its glyph
15689 represents a newline and point is on that newline. Fixes cursor
15690 positioning on the newline at EOL of R2L text within L2R
15691 paragraph, and vice versa.
15692 (try_cursor_movement): Check continued rows, in addition to
15693 continuation rows. Fixes unwarranted scroll when point enters a
15694 continued line of R2L text within an L2R paragraph, or vice versa.
15695 (cursor_row_p): Consider the case of point being equal to
15696 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15697 from the end of a short line to the beginning of a continued line
15698 of R2L text within L2R paragraph.
15699 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15700 composed characters.
15702 * bidi.c (bidi_check_type): Use xassert.
15703 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
15706 2011-08-23 Eli Zaretskii <eliz@gnu.org>

15713 * nsfont.m (ns_otf_to_script): Fix typo.
15715 2011-08-22 Kenichi Handa <handa@m17n.org>
15717 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15718 extra slot even if the purpose is char-code-property-table.
15720 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15722 * xdisp.c (redisplay_window): When computing centering_position,
15723 account for the height of the header line. (Bug#8874)
15725 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15726 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15727 candidate is selected by the mouse, and that candidate has a
15728 composed character under the mouse.
15730 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15731 coordinates reported by pos-visible-in-window-p for a composed
15732 character in column zero.
15734 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15736 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15738 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15740 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15741 consider it a hit if to_charpos is anywhere in the range of the
15742 composed buffer positions.
15744 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15746 * image.c (gif_load): Don't assume that each subimage has the same
15747 dimensions as the base image. Handle disposal method that is
15748 "undefined" by the gif spec (Bug#9335).
15750 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15752 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15755 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15757 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15758 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15759 from an Org mode buffer to a Speedbar frame.
15761 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15762 a composition, take its buffer position from IT->cmp_it.charpos.
15763 Fixes cursor positioning at the beginning of a line that begins
15764 with a composed character.
15766 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15768 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15769 character bidirectional type, use STRONG_L instead. Fixes crashes
15770 in a buffer produced by `describe-categories'.
15772 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15773 members before the level stack, so they would be saved and
15774 restored when copying iterator state. Fixes incorrect reordering
15775 around TABs covered by display properties.
15777 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15779 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15849 * xdisp.c (move_it_in_display_line_to): Don't invoke
15850 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15851 ppos_it. Fixes vertical cursor motion when line beginning is
15852 covered by an image. (Bug#9296)
15854 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15856 * nsterm.h (ns_run_ascript): Declare.

15860 (ns_run_ascript): New function.
15861 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15862 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15863 the event loop. Get status from as_status (Bug#7276).
15865 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15866 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15867 the event loop (Bug#7276).
15869 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15893 (Fnetwork_interface_list): Allocate in increments of bytes instead
15894 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15895 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15897 (struct ifflag_def): notrailers is smart on OSX.
15898 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15899 Get hardware address with getifaddrs if available.
15901 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15903 * xdisp.c (iterate_out_of_display_property): xassert that
15904 IT->position is set to within IT->object's boundaries. Break from

15907 Set IT->current to match the bidi iterator unconditionally.
15908 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15909 entry. Force push_it to save on the stack the current
15910 buffer/string position, to be restored by pop_it. Fix flags in
15911 the iterator structure wrt the object coming from a display
15912 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15913 properties. (Bug#9284)
15915 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15917 * fontset.c (fontset_get_font_group): Add proper type checks.

15945 restore_point_unwind (Bug#5984).
15947 2011-08-07 Juri Linkov <juri@jurta.org>
15949 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

15954 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15955 display property strides EOL and includes a newline, as in
15956 longlines-mode. (Bug#9254)
15957 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15958 word-wrap under bidirectional display. (Bug#9224)
15960 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15961 is non-zero, even if the data buffer is NULL. Fixes a crash in
15962 vertical-motion with longlines-mode. (Bug#9254)
15964 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15966 * bidi.c <bidi_cache_total_alloc>: Now static.

15969 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15972 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15973 amount allocated this far in `bidi_cache_total_alloc'.
15974 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15975 non-zero, only free the data buffer without restoring the cache
15976 contents. All callers changed.
15978 * dispextern.h (bidi_unshelve_cache): Update prototype.
15980 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15981 (move_it_in_display_line, move_it_to)
15982 (move_it_vertically_backward, move_it_by_lines): Replace the call
15983 to xfree to an equivalent call to bidi_unshelve_cache.
15984 (move_it_in_display_line_to): Fix logic of returning
15985 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15987 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15989 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

16041 DISP_PROP_P, and pass it to compute_display_string_pos.
16042 Only handle text covered by a display string if DISP_PROP_P is returned
16043 non-zero. All callers of bidi_fetch_char changed.
16045 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16047 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16049 2010-12-03 Don March <don@ohspite.net>
16051 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16052 last character M-[char] is translated to ESC [char] (bug#7541).
16054 2011-08-02 Kenichi Handa <handa@m17n.org>
16056 * lisp.h (uniprop_table): Extern it.
16058 * chartab.c (uniprop_table): Make it non-static.
16060 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16062 * xdisp.c (forward_to_next_line_start): Accept additional argument
16063 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16065 (reseat_at_next_visible_line_start): Use the bidi iterator state
16066 returned by forward_to_next_line_start to restore the state of
16067 it->bidi_it after backing up to previous newline. (Bug#9212)
16069 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16071 * regex.c (re_comp): Protoize.
16072 (re_exec): Fix return type.
16073 (regexec): Fix type of `ret'. (Bug#9203)
16075 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16077 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16078 This is needed if max-image-size is a floating-point number.
16080 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16082 * print.c (print_object): Print empty symbol as ##.
16084 * lread.c (read1): Read ## as empty symbol.
16086 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16088 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16089 setting frame foreground color (Bug#9175).
16090 (x_set_background_color): Likewise.
16092 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16093 contents (Bug#9176).
16094 (EmacsTooltip -init): Remove bezels and add shadows to
16097 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16098 or scroll bar (Bug#8470).
16100 * nsfont.m (nsfont_open): Remove assignment to voffset and
16101 unnecessary vars hshink, expand, hd, full_height, min_height.
16102 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16104 * nsterm.h (nsfont_info): Remove voffset field.
16106 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16108 Implement strike-through and overline on NextStep (Bug#8863).
16110 * nsfont.m (nsfont_open): Use underline position provided by font,
16111 instead of hard-coded value of 2.
16112 (nsfont_draw): Call ns_draw_text_decoration instead.
16114 * nsterm.h: Add declaration for ns_draw_text_decoration.
16116 * nsterm.m (ns_draw_text_decoration): New function for drawing
16117 underline, overline, and strike-through.
16118 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16119 ns_draw_text_decoration. Change treatment of cursor drawing to
16120 accommodate underlining, etc.
16122 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16124 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16127 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16129 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16130 Without this fix, if a signal arrives just after memory fills up,
16131 'malloc' might be invoked reentrantly.
16133 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16134 In other words, assume that every image size is allowed, on non-X
16135 hosts. This assumption is probably wrong, but it lets Emacs compile.
16137 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16139 * regex.c (re_iswctype): Convert return values to boolean.
16141 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16143 * xdisp.c (compute_display_string_pos): Don't use cached display
16144 string position if the buffer had its restriction changed.
16147 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16149 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16151 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16153 Integer signedness and overflow and related fixes. (Bug#9079)
16155 * bidi.c: Integer size and overflow fixes.
16156 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16157 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16158 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16159 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16160 (bidi_find_other_level_edge):
16161 Use ptrdiff_t instead of EMACS_INT where either will do.
16162 This works better on 32-bit hosts configured --with-wide-int.
16163 (bidi_cache_ensure_space): Check for size-calculation overflow.
16164 Use % rather than repeated addition, for better worst-case speed.
16165 Don't set bidi_cache_size until after xrealloc returns, because it
16167 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16168 (bidi_cache_ensure_space): Also check that the bidi cache size
16169 does not exceed that of the largest Lisp string or buffer. See Eli
16170 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16172 * alloc.c (__malloc_size_t): Remove.
16173 All uses replaced by size_t. See Andreas Schwab's note
16174 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16176 * image.c: Improve checking for integer overflow.
16177 (check_image_size): Assume that f is nonnull, since
16178 it is always nonnull in practice. This is one less thing to
16179 worry about when checking for integer overflow later.
16180 (x_check_image_size): New function, which checks for integer
16181 overflow issues inside X.
16182 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16183 This removes the need for a memory_full check.
16184 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16185 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16186 (xbm_read_bitmap_data): Change locals back to 'int', since
16187 their values must fit in 'int'.
16188 (xpm_load_image, png_load, tiff_load):
16189 Invoke x_create_x_image_and_pixmap earlier,
16190 to avoid much needless work if the image is too large.
16191 (tiff_load): Treat overly large images as if
16192 x_create_x_image_and_pixmap failed, not as malloc failures.
16193 (gs_load): Use x_check_image_size.
16195 * gtkutil.c: Omit integer casts.
16196 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16197 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16199 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16201 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16202 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16203 would wrongly return t on a 64-bit host.
16205 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16206 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16207 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16208 and therefore cause GCC to emit a bogus diagnostic in some cases.
16210 * image.c: Integer signedness and overflow and related fixes.
16211 This is not an exhaustive set of fixes, but it's time to
16212 record what I've got.
16213 (lookup_pixel_color, check_image_size): Remove redundant decls.
16214 (check_image_size): Don't assume that arbitrary EMACS_INT values
16215 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16216 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16217 (tiff_load, imagemagick_load_image):
16218 Check for overflow in size calculations.
16219 (x_create_x_image_and_pixmap): Remove unnecessary test for
16220 xmalloc returning NULL; that can't happen.
16221 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16222 (xpm_color_bucket): Use better integer hashing function.
16223 (xpm_cache_color): Don't possibly over-allocate memory.
16224 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16225 (gif_memory_source):
16226 Use ptrdiff_t, not int or size_t, to record sizes.
16227 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16228 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16229 either works, as we prefer signed integers.
16230 (tiff_read_from_memory, tiff_write_from_memory):
16231 Return tsize_t, not size_t, since that's what the TIFF API wants.
16232 (tiff_read_from_memory): Don't fail simply because the read would
16233 go past EOF; instead, return a short read.
16234 (tiff_load): Omit no-longer-needed casts.
16235 (Fimagemagick_types): Don't assume size fits into 'int'.
16237 Improve hashing quality when configured --with-wide-int.
16238 * fns.c (hash_string): New function, taken from sxhash_string.
16239 Do not discard information about ASCII character case; this
16240 discarding is no longer needed.
16241 (sxhash-string): Use it. Change sig to match it. Caller changed.
16242 * lisp.h: Declare it.
16243 * lread.c (hash_string): Remove, since we now use fns.c's version.
16244 The fns.c version returns a wider integer if --with-wide-int is
16245 specified, so this should help the quality of the hashing a bit.
16247 * emacs.c: Integer overflow minor fix.
16248 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16249 Define only if GNU_LINUX.
16250 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16252 * dispnew.c: Integer signedness and overflow fixes.
16253 Remove unnecessary forward decls, that were a maintenance hassle.
16254 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16256 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16257 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16258 (prepare_desired_row, line_draw_cost):
16259 Use int, not unsigned, where either works.
16260 (save_current_matrix, restore_current_matrix):
16261 Use ptrdiff_t, not size_t, where either works.
16262 (init_display): Check for overflow more accurately, and without
16263 relying on undefined behavior.
16265 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16266 Remove, replacing with the new symbols in lisp.h. All uses changed.
16267 * fileio.c (make_temp_name):
16268 * filelock.c (lock_file_1, lock_file):
16269 * xdisp.c (message_dolog):
16270 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16271 Use pMd etc. instead.
16272 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16273 replacing the pWIDE etc. symbols removed from editfns.c.
16275 * keyboard.h (num_input_events): Now uintmax_t.
16276 This is (very slightly) less likely to mess up due to wraparound.
16279 * buffer.c: Integer signedness fixes.
16280 (alloc_buffer_text, enlarge_buffer_text):
16281 Use ptrdiff_t rather than size_t when either will do, as we prefer
16284 * alloc.c: Integer signedness and overflow fixes.
16285 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16286 (__malloc_size_t): Default to size_t, not to int.
16287 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16288 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16289 Prefer ptrdiff_t to size_t when either would do, as we prefer
16291 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16292 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16293 Now const. Initialize with values that are in range even if char
16295 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16296 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16297 These functions do the right thing with sizes > 2**32.
16298 (check_depth): Now ptrdiff_t, not int.
16299 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16300 Adjust to new way of storing sizes. Check for size overflow bugs
16302 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16303 slightly wrong anyway, as it missed one instance of
16304 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16305 (refill_memory_reserve): Omit needless cast to size_t.
16306 (mark_object_loop_halt): Mark as externally visible.
16308 * xselect.c: Integer signedness and overflow fixes.
16309 (Fx_register_dnd_atom, x_handle_dnd_message):
16310 Use ptrdiff_t, not size_t, since we prefer signed.
16311 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16312 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16313 x_dnd_atoms_size and x_dnd_atoms_length.
16315 * doprnt.c: Prefer signed to unsigned when either works.
16317 * doprnt.c (doprnt):
16319 * xdisp.c (vmessage):
16320 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16321 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16322 prefer signed arithmetic to avoid comparison confusion.
16323 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16324 but is a bit tricky.
16326 Assume freestanding C89 headers, string.h, stdlib.h.
16327 * data.c, doprnt.c, floatfns.c, print.c:
16328 Include float.h unconditionally.
16329 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16330 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16331 * regex.c: Likewise for stddef.h, string.h.
16332 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16333 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16334 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16335 (STDC_HEADERS): Remove obsolete defines.
16336 * sysdep.c: Include limits.h unconditionally.
16338 Assume support for memcmp, memcpy, memmove, memset.
16339 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16340 * regex.c (memcmp, memcpy):
16341 Remove; we assume C89 now.
16343 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16344 (__malloc_safe_bcopy): Remove; no longer needed.
16346 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16347 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16348 well either way, and we prefer signed to unsigned.
16350 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16352 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16353 closes the connection while we're reading (bug#9182).
16355 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16357 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16358 are specified (Bug#9168).
16360 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16362 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16363 Found by GCC static checking and --with-wide-int on a 32-bit host.
16365 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16367 * xdisp.c (compute_display_string_pos): Fix logic of caching
16368 previous display string position. Initialize cached_prev_pos to
16369 -1. Fixes slow-down at the beginning of a buffer.
16371 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16373 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16374 for attrs[LFACE_FONTSET_INDEX].
16376 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16378 * xml.c (parse_region): Remove unused local
16379 that was recently introduced.
16381 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16383 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16384 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16386 * xdisp.c (move_it_in_display_line_to): Record the best matching
16387 position for TO_CHARPOS while scanning the line, and restore it on
16388 exit if none of the characters scanned was an exact match.
16389 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16390 when exact match is impossible due to invisible text, and the
16391 lines are truncated.
16393 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16395 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16398 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16400 Fix a significant slow-down of cursor motion with C-n, C-p,
16401 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16402 auto-repeat under bidi redisplay in fontified buffers.
16403 * xdisp.c (compute_stop_pos_backwards): New function.
16404 (next_element_from_buffer): Call compute_stop_pos_backwards to
16405 find a suitable prev_stop when we find ourselves before
16407 (reseat): Don't look for prev_stop, as that could mean a very long
16409 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16410 <cached_disp_overlay_modiff>: Cache for last found display string
16412 (compute_display_string_pos): Return the cached position if asked
16413 about the same buffer in the same area of character positions, and
16414 the buffer wasn't changed since the time the display string
16415 position was cached.
16417 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16419 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16420 is an integer, which is important for empty lines. (Bug#9149)
16422 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16424 * frame.c (Fmodify_frame_parameters): In tty case, update the
16425 default face if necessary (Bug#4238).
16427 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16429 * editfns.c (Fstring_to_char): No need to explain what a character
16430 is in the docstring (Bug#6576).
16432 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16434 * xml.c (parse_region): Make sure we always return a tree.
16436 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16438 * xml.c (parse_region): If a document contains only comments,
16441 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16443 * xml.c (make_dom): Return comments, too.
16445 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16448 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16449 and the surrounding thread.
16450 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16451 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16452 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16454 * s/openbsd.h (BROKEN_SIGIO): Define.
16455 * unexelf.c (unexec) [__OpenBSD__]:
16456 Don't update the .mdebug section of the Alpha COFF symbol table.
16458 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16460 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16463 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16465 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16466 This fixes some race conditions on the permissions of any newly
16469 * alloc.c (valid_pointer_p): Use pipe, not open.
16470 This fixes some permissions issues when debugging.
16472 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16473 If fchown fails to set both uid and gid, try to set just gid,
16474 as that is sometimes allowed. Adjust the file's mode to eliminate
16475 setuid or setgid bits that are inappropriate if fchown fails.
16477 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16479 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16480 to compare Lisp_Objects.
16481 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16482 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16483 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16485 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16487 * lread.c (read_integer): Unread even EOF character.
16488 (read1): Likewise. Properly record start position of symbol.

16495 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16496 This works around a problem with the previous change to Fcopy_file.
16497 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16498 and without this change, GCC might complain about discarding
16499 fchown's return value.
16501 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16503 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

16526 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16528 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16529 quotes the next character, and doesn't affect other longer
16530 sequences (bug#8935).

16533 `eval-buffer' and `eval-defun' that's affected by

16544 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16545 (elsz): Now a signed constant, not a size_t var. We prefer signed
16546 types to unsigned, to avoid integer comparison confusion. Without
16547 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16548 "cannot optimize loop, the loop counter may overflow", a symptom
16550 * indent.c (Fvertical_motion): Mark locals as initialized.
16551 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16553 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

16597 the iterator is before prev_stop.
16598 (init_iterator): Initialize bidi_p from the default value of

16643 instead, set the first_elt flag in the bidi iterator, to produce
16645 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16646 (push_display_prop): xassert that we are iterating a buffer.

16650 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16651 correctly. Don't assume unibyte strings are not bidi-reordered.

17079 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17116 Random fixes. E.g., (random) never returned negative values.
17117 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17118 subseconds part to the entropy, as that's a bit more random.
17119 Prefer signed to unsigned, since the signedness doesn't matter and
17120 in general we prefer signed. When given a limit, use a
17121 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17122 latter isn't right if USE_2_TAGS_FOR_INTS.
17123 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17124 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17136 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17137 This is more efficient than Ffile_directory_p and avoids a minor race.

17141 * buffer.c (Foverlay_put): Say what the return value is
17144 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17148 error be more correct.
17150 * fns.c (Frequire): Remove the mention of the .gz files, since

17167 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17168 Also (re)move comments that are misplaced or no longer relevant.

17197 * lread.c (syms_of_lread): Mention single symbols defined by

17269 * eval.c (struct backtrace): Simplify and port the data structure.
17270 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17271 signed bit field, as this assumption is not portable and it makes
17272 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17273 "char debug_on_exit : 1" as this is not portable either; instead,
17274 use the portable "unsigned int debug_on_exit : 1". Remove unused
17275 member evalargs. Remove obsolete comments about cc bombing out.

17367 pending. Suggested by Jan Djärv (Bug#8869).
17369 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
17371 Use gnulib's dup2 module instead of rolling our own.
17372 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17374 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17376 * dispnew.c (scrolling_window): Before scrolling, turn off a

17439 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17441 Integer and buffer overflow fixes (Bug#8873).
17443 * print.c (printchar, strout): Check for string overflow.
17444 (PRINTPREPARE, printchar, strout):
17445 Don't set size unless allocation succeeds.
17447 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17448 for sizes. Check for string overflow more accurately.
17449 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17451 * macros.c: Integer and buffer overflow fixes.
17452 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17453 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17454 Use ptrdiff_t, not int, for sizes.
17455 Don't increment bufsize until after realloc succeeds.
17456 Check for size-calculation overflow.
17457 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17459 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17461 * lread.c: Integer overflow fixes.
17462 (read_integer): Radix is now EMACS_INT, not int,
17463 to improve quality of diagnostics for out-of-range radices.
17464 Calculate buffer size correctly for out-of-range radices.
17465 (read1): Check for integer overflow in radices, and in
17466 read-circle numbers.
17467 (read_escape): Avoid int overflow.
17468 (Fload, openp, read_buffer_size, read1)
17469 (substitute_object_recurse, read_vector, read_list, map_obarray):
17470 Use ptrdiff_t, not int, for sizes.

17485 2011-06-22 Leo Liu <sdl.web@gmail.com>
17487 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17488 Move to minibuffer.el.
17490 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17492 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17493 The following patches are for when GLYPH_DEBUG && !XASSERT.
17494 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17495 * dispnew.c (flush_stdout):
17496 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17497 Mark as externally visible.
17498 * dispnew.c (check_window_matrix_pointers): Now static.
17499 * dispnew.c (window_to_frame_vpos):
17500 * xfns.c (unwind_create_frame):
17501 * xterm.c (x_check_font): Remove unused local.
17502 * scroll.c (CHECK_BOUNDS):
17503 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17504 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17505 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17506 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17507 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17509 (debug_method_add): Use va_list and vsprintf rather than relying
17510 on undefined behavior with wrong number of arguments.
17511 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17512 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17513 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17514 since we're not interested in debugging glyphs with old libraries.
17515 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17516 GCC 4.6.0's static checking.
17518 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17520 Integer overflow and signedness fixes (Bug#8873).

17529 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17530 (x_create_bitmap_from_xpm_data):
17531 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17532 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17534 * xfaces.c (load_pixmap):

17536 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17537 (.bitmaps_last, struct x_output.icon_bitmap):
17538 Use ptrdiff_t, not int, for bitmap indexes.
17539 (x_allocate_bitmap_record): Check for size overflow.
17540 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17542 Use ptrdiff_t, not int, for overlay counts.
17543 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17544 * editfns.c (overlays_around, get_pos_property):
17545 * textprop.c (get_char_property_and_overlay):
17546 * xdisp.c (next_overlay_change, note_mouse_highlight):
17547 * xfaces.c (face_at_buffer_position):
17548 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17549 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17550 (Fnext_overlay_change, Fprevious_overlay_change)
17551 (mouse_face_overlay_overlaps, Foverlays_in):
17552 Use ptrdiff_t, not int, for sizes.
17553 (overlays_at, overlays_in): Check for size-calculation overflow.
17555 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17557 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17558 (x_session_initialize): Do not assume string length fits in int.
17560 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17561 This is unlikely, but can occur if DPI is outlandish.
17563 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17564 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17566 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17567 * xrdb.c (magic_file_p, search_magic_path):
17568 Omit last arg SUFFIX; it was always 0. All callers changed.
17569 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17571 * xfont.c (xfont_match): Avoid need for strlen.
17573 * xfns.c: Don't assume strlen fits in int.
17574 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17576 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17577 not unsigned long, as we prefer signed integers. All callers changed.
17578 Detect integer overflow in repeat count.
17579 (message_dolog): Don't assume print length fits in 39 bytes.
17580 (display_mode_element): Don't assume strlen fits in int.
17582 * termcap.c: Don't assume sizes fit in int and never overflow.
17583 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17584 (gobble_line): Check for size-calculation overflow.
17586 * minibuf.c (Fread_buffer):
17587 * lread.c (intern, intern_c_string):
17588 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17592 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17594 * font.c: Don't assume string length fits in int.
17595 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17596 Use ptrdiff_t, not int.
17597 (font_intern_prop): Don't assume string length fits in int.
17598 Don't assume integer property fits in fixnum.
17599 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17601 * filelock.c: Fix some buffer overrun and integer overflow issues.
17602 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17603 Reformulate so as not to need the command string.
17604 Invoke gzip -cd rather than gunzip, as it's more portable.
17605 (lock_info_type, lock_file_1, lock_file):
17606 Don't assume pid_t and time_t fit in unsigned long.
17607 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17608 (current_lock_owner): Prefer signed type for sizes.
17609 Use memcpy, not strncpy, where memcpy is what is really wanted.
17610 Don't assume (via atoi) that time_t and pid_t fit in int.
17611 Check for time_t and/or pid_t out of range, e.g., via a network share.
17612 Don't alloca where an auto var works fine.
17614 * fileio.c: Fix some integer overflow issues.
17615 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17616 Don't assume string length fits in int.
17617 (directory_file_name): Don't assume string length fits in long.
17618 (make_temp_name): Don't assume pid fits in int, or that its print
17619 length is less than 20.
17621 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17623 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17625 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17627 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17628 We prefer signed integers, even for size calculations.
17630 * emacs.c: Don't assume string length fits in 'int'.
17631 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17632 (main): Don't invoke strlen when not needed.
17634 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17635 (XD_DEBUG_MESSAGE): Don't waste a byte.
17637 * callproc.c (getenv_internal_1, getenv_internal)
17638 (Fgetenv_internal):
17639 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17641 * lread.c (invalid_syntax): Omit length argument.
17642 All uses changed. This doesn't fix a bug, but it simplifies the
17643 code away from its former Hollerith-constant appearance, and it's
17644 one less 'int' to worry about when looking at integer-overflow issues.
17645 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17647 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17648 This didn't break anything, but it didn't help either.
17649 It's confusing to put a bogus integer in a place where the actual
17650 value does not matter.
17651 (LIST_END_P): Remove unused macro and its bogus comment.
17652 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17654 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17655 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17657 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17658 We prefer signed types, and the value cannot exceed the EMACS_INT
17659 range anyway (because otherwise the length would not be representable).
17660 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17661 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17662 This avoids a GCC warning when WIDE_EMACS_INT.
17664 * indent.c (sane_tab_width): New function.
17665 (current_column, scan_for_column, Findent_to, position_indentation)
17666 (compute_motion): Use it. This is just for clarity.
17667 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17669 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

17672 * composite.c (composition_gstring_put_cache):
17673 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17675 * editfns.c, insdel.c:
17676 Omit unnecessary forward decls, to simplify future changes.
17678 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17680 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17682 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17683 Use much-faster test for byte-length change.
17684 Don't assume string byte-length fits in 'int'.
17685 Check that character arg fits in 'int'.
17686 (mapcar1): Declare byte as byte, for clarity.
17688 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17690 * fns.c (concat): Catch string overflow earlier.
17691 Do not rely on integer wraparound.
17693 * dispextern.h (struct it.overlay_strings_charpos)
17694 (struct it.selective): Now EMACS_INT, not int.
17695 * xdisp.c (forward_to_next_line_start)
17696 (back_to_previous_visible_line_start)
17697 (reseat_at_next_visible_line_start, next_element_from_buffer):
17698 Don't arbitrarily truncate the value of 'selective' to int.
17700 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17702 * composite.c: Don't truncate sizes to 'int'.
17703 (composition_gstring_p, composition_reseat_it)
17704 (composition_adjust_point): Use EMACS_INT, not int.
17705 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17706 not EMACS_UINT, for indexes.
17708 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17710 * buffer.c: Include <verify.h>.
17711 (struct sortvec.priority, struct sortstr.priority):
17712 Now EMACS_INT, not int.
17713 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17714 (struct sortstr.size, record_overlay_string)
17715 (struct sortstrlist.size, struct sortlist.used):
17716 Don't truncate size to int.
17717 (record_overlay_string): Check for size-calculation overflow.
17718 (init_buffer_once): Check at compile-time, not run-time.
17720 2011-06-22 Jim Meyering <meyering@redhat.com>
17722 Don't leak an XBM-image-sized buffer
17723 * image.c (xbm_load): Free the image buffer after using it.
17725 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17728 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17729 that Sun C diagnosed.
17730 * fns.c (secure_hash): Fix pointer signedness issue.
17731 * intervals.c (static_offset_intervals): New function.
17732 (offset_intervals): Use it.
17734 2011-06-21 Leo Liu <sdl.web@gmail.com>
17737 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17740 * fns.c (secure_hash): Rename from crypto_hash_function and change
17741 the first arg to accept symbols.
17742 (Fsecure_hash): New primitive.
17743 (syms_of_fns): New symbols.
17745 2011-06-20 Deniz Dogan <deniz@dogan.se>
17747 * process.c (Fset_process_buffer): Clarify return value in
17750 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17752 * dispnew.c (add_window_display_history): Use BVAR.
17754 * xdisp.c (debug_method_add): Use BVAR.
17755 (check_window_end, dump_glyph_matrix, dump_glyph)
17756 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17758 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17761 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17762 check till after the cache is created in init_frame_faces.
17764 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17766 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17768 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17770 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17771 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17772 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17774 Improve buffer-overflow checking (Bug#8873).
17775 * fileio.c (Finsert_file_contents):
17776 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17777 Remove the old (too-loose) buffer overflow checks.
17778 They weren't needed, since make_gap checks for buffer overflow.
17779 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17780 The old code merely checked for Emacs fixnum overflow, and relied
17781 on undefined (wraparound) behavior. The new code avoids undefined
17782 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17784 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17785 Tune. Don't use wider integers than needed. Don't use alloca.
17786 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17788 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17790 * insdel.c, lisp.h (buffer_overflow): New function.
17791 (insert_from_buffer_1, replace_range, replace_range_2):
17792 * insdel.c (make_gap_larger):
17793 * editfns.c (Finsert_char):
17794 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17796 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17798 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17800 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17802 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17803 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17805 * fileio.c: Don't assume EMACS_INT fits in off_t.
17806 (emacs_lseek): New static function.
17807 (Finsert_file_contents, Fwrite_region): Use it.
17808 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17810 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17812 * fns.c: Don't overflow int when computing a list length.
17813 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17814 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17815 truncation on 64-bit hosts. Check for QUIT every
17816 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17817 faster and is responsive enough.
17818 (Flength): Report an error instead of overflowing an integer.
17819 (Fsafe_length): Return a float if the value is not representable
17820 as a fixnum. This shouldn't happen except in contrived situations.
17821 (Fnthcdr, Fsort): Don't assume list length fits in int.
17822 (Fcopy_sequence): Don't assume vector length fits in int.
17824 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17825 (header_size, word_size): New constants.
17826 (allocate_vectorlike): Don't check size overflow here.
17827 (allocate_vector): Check it here instead, since this is the only
17828 caller of allocate_vectorlike that could cause overflow.
17829 Check that the new vector's length is representable as a fixnum.
17831 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17832 The previous code was bogus. For example, next_almost_prime (32)
17833 returned 39, which is undesirable as it is a multiple of 3; and
17834 next_almost_prime (24) returned 25, which is a multiple of 5 so
17835 why was the code bothering to check for multiples of 7?
17837 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17839 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17841 Variadic C functions now count arguments with ptrdiff_t.
17842 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17843 Back then I didn't know that the Emacs coding style prefers signed int.
17844 Also, in the meantime I found a few more instances where arguments
17845 were being counted with int, which may truncate counts on 64-bit
17846 machines, or EMACS_INT, which may be unnecessarily wide.
17847 * lisp.h (struct Lisp_Subr.function.aMANY)
17848 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17849 Arg counts are now ptrdiff_t, not size_t.
17850 All variadic functions and their callers changed accordingly.
17851 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17852 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17853 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17854 * callint.c (Fcall_interactively): Check arg count for overflow,
17855 to avoid potential buffer overrun. Use signed char, not 'int',
17856 for 'varies' array, so that we needn't bother to check its size
17857 calculation for overflow.
17858 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17859 * eval.c (apply_lambda):
17860 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17861 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17862 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17864 * callint.c (Fcall_interactively): Don't use index var as event count.
17866 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17867 * mem-limits.h (SIZE): Remove; no longer used.
17869 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17871 Remove unnecessary casts.
17872 * xterm.c (x_term_init):
17873 * xfns.c (x_set_border_pixel):
17874 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17875 These aren't needed now that we assume ANSI C.
17877 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17878 It's more likely to cause problems (due to unsigned overflow)
17881 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17883 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17885 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17887 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17889 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17891 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17893 GLYPH_CODE_FACE returns EMACS_INT, not int.
17894 * dispextern.h (merge_faces):
17895 * xfaces.c (merge_faces):
17896 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17897 Don't assume EMACS_INT fits in int.
17899 * character.h (CHAR_VALID_P): Remove unused parameter.
17900 * fontset.c, lisp.h, xdisp.c: All uses changed.
17902 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17904 * fns.c (concat): Minor tuning based on overflow analysis.
17905 This doesn't fix any bugs. Use int to hold character, instead
17906 of constantly refetching from Emacs object. Use XFASTINT, not
17907 XINT, for value known to be a character. Don't bother comparing
17908 a single byte to 0400, as it's always less.
17910 * floatfns.c (Fexpt):
17911 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17913 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17916 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17918 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17919 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17920 incorrectly succeed when S was a string, because 4294967386 was
17921 truncated before it was used.
17923 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17924 Otherwise, an out-of-range integer could cause undefined behavior
17927 * composite.c: Use int, not EMACS_INT, for characters.
17928 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17929 EMACS_INT, for values that are known to be in character range.
17930 This doesn't fix any bugs but is the usual style inside Emacs and
17931 may generate better code on 32-bit machines.
17933 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17934 This is for reasons similar to the recent CHAR_STRING fix.
17935 * charset.c (Fencode_char): Check that character arg is actually
17936 a character. Pass an int to ENCODE_CHAR.
17937 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17938 wider than 'int', as a compile-time check to prevent future regressions
17941 * character.c (char_string): Remove unnecessary casts.
17943 Make sure a 64-bit char is never passed to CHAR_STRING.
17944 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17945 by silently ignoring the top 32 bits, allowing some values
17946 that were far too large to be valid characters.
17947 * character.h: Include <verify.h>.
17948 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17949 arguments are no wider than unsigned, as a compile-time check
17950 to prevent future regressions in this area.
17952 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17953 (Fsubst_char_in_region):
17955 * xdisp.c (decode_mode_spec_coding):
17956 Adjust to CHAR_STRING's new requirement.
17957 * editfns.c (Finsert_char, Fsubst_char_in_region):
17958 * fns.c (concat): Check that character args are actually
17959 characters. Without this test, these functions did the wrong
17960 thing with wildly out-of-range values on 64-bit hosts.
17962 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17963 These casts should not be needed on 32-bit hosts, either.
17964 * keyboard.c (read_char):
17965 * lread.c (Fload): Remove casts to unsigned.
17967 * lisp.h (UNSIGNED_CMP): New macro.
17968 This fixes comparison bugs on 64-bit hosts.
17969 (ASCII_CHAR_P): Use it.
17970 * casefiddle.c (casify_object):
17971 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17972 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17973 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17974 * dispextern.h (FACE_FROM_ID):
17975 * keyboard.c (read_char): Use UNSIGNED_CMP.
17977 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17978 not to EMACS_INT, to avoid GCC warning.
17980 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17982 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17983 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17984 isn't needed on 32-bit machines.
17986 * buffer.c (Fgenerate_new_buffer_name):
17987 Use EMACS_INT for count, not int.
17988 (advance_to_char_boundary): Return EMACS_INT, not int.
17990 * data.c (Qcompiled_function): Now static.
17992 * window.c (window_body_lines): Now static.
17994 * image.c (gif_load): Rename local to avoid shadowing.
17996 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17997 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17998 * alloc.c (make_save_value): Integer argument is now of type
17999 ptrdiff_t, not int.
18000 (mark_object): Use ptrdiff_t, not int.
18001 * lisp.h (pD): New macro.
18002 * print.c (print_object): Use it.
18004 * alloc.c: Use EMACS_INT, not int, to count objects.
18005 (total_conses, total_markers, total_symbols, total_vector_size)
18006 (total_free_conses, total_free_markers, total_free_symbols)
18007 (total_free_floats, total_floats, total_free_intervals)
18008 (total_intervals, total_strings, total_free_strings):
18009 Now EMACS_INT, not int. All uses changed.
18010 (Fgarbage_collect): Compute overall total using a double, so that
18011 integer overflow is less likely to be a problem. Check for overflow
18012 when converting back to an integer.
18013 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18014 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18015 These were 'int' variables that could overflow on 64-bit hosts;
18016 they were never used, so remove them instead of repairing them.
18017 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18018 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18019 Previously, this ceilinged at INT_MAX, but that doesn't work on
18021 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18023 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18024 (allocate_vectorlike): Check for ptrdiff_t overflow.
18025 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18026 when a (possibly-narrower) signed value would do just as well.
18027 We prefer using signed arithmetic, to avoid comparison confusion.
18029 * alloc.c: Catch some string size overflows that we were missing.
18030 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18031 for convenience in STRING_BYTES_MAX.
18032 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18033 The definition here is exact; the one in lisp.h was approximate.
18034 (allocate_string_data): Check for string overflow. This catches
18035 some instances we weren't catching before. Also, it catches
18036 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18037 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18038 and ptrdiff_t and EMACS_INT are both 64 bits.
18040 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18041 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18042 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18044 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18046 * alloc.c (Fmake_string): Check for out-of-range init.
18048 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18050 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18052 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18054 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18055 xg_get_default_scrollbar_width.
18057 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18058 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18059 (style_changed_cb): Call update_theme_scrollbar_width and call
18060 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18061 all frames (Bug#8505).
18062 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18063 Call gtk_window_set_resizable if HAVE_GTK3.
18064 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18065 and height if HAVE_GTK3 (Bug#8505).
18066 (scroll_bar_width_for_theme): New variable.
18067 (update_theme_scrollbar_width): New function.
18068 (xg_get_default_scrollbar_width): Move code to
18069 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18070 (xg_initialize): Call update_theme_scrollbar_width.
18072 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18074 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18076 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18078 * frame.c (make_frame): Call other_buffer_safely instead of
18081 * window.c (temp_output_buffer_show): Call display_buffer with
18082 second argument Vtemp_buffer_show_specifiers and reset latter
18083 immediately after the call.
18084 (Vtemp_buffer_show_specifiers): New variable.
18085 (auto_window_vscroll_p, next_screen_context_lines)
18086 (Vscroll_preserve_screen_position): Remove leading asterisks from
18089 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18091 Fix minor problems found by GCC 4.6.0 static checking.
18092 * buffer.c (Qclone_number): Remove for now, as it's unused.
18093 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18094 (record_buffer): Remove unused local.
18095 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18096 (set_frame_buffer_list): Remove; unused.
18097 * frame.h (other_visible_frames): Remove decl.
18098 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18099 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18100 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18102 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18103 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18104 Define only if HAVE_GPM.
18105 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18106 (update_hints_inhibit): Remove; never set. All uses removed.
18107 * widgetprv.h (emacsFrameClassRec): Remove decl.
18108 * window.c (delete_deletable_window): Now returns void, since it
18109 wasn't returning anything.
18110 (compare_window_configurations): Remove unused locals.
18111 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18112 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18113 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18114 the same widths as pointers. This follows up on the 2011-05-06 patch.
18115 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18116 * xterm.h: Likewise.

18122 (LISP_H): Add lib/intprops.h.
18124 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18126 * image.c (gif_load): Add animation frame delay to the metadata.
18127 (syms_of_image): Use DEFSYM. New symbol `delay'.
18129 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18131 * window.c (delete_deletable_window): Re-add.
18132 (Fset_window_configuration): Rewrite to handle dead buffers and
18133 consequently deletable windows.
18134 (window_tree, Fwindow_tree): Remove. Supply functionality in
18136 (compare_window_configurations): Simplify code.
18138 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18140 * image.c (imagemagick_load_image): Fix type mismatch.
18141 (Fimagemagick_types): Likewise.
18143 * window.h (replace_buffer_in_windows): Declare.
18145 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18147 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18148 Qclone_number. Remove external declaration of Qdelete_window.
18149 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18151 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18152 Run Qbuffer_list_update_hook if allowed.
18153 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18154 buffer list implementation.
18155 (other_buffer_safely): New function.
18156 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18157 calls to replace_buffer_in_windows and
18158 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18160 (record_buffer): Inhibit quitting and rewrite using quittable
18161 functions. Run Qbuffer_list_update_hook if allowed.
18162 (Frecord_buffer, Funrecord_buffer): New functions.
18163 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18164 Move switch-to-buffer to window.el.
18165 (bury-buffer): Move to window.el.
18166 (Vbuffer_list_update_hook): New variable.
18168 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18171 * window.h (resize_frame_windows): Move up in code.
18172 (Fwindow_frame): Remove EXFUN.
18173 (replace_buffer_in_all_windows): Remove prototype.
18174 (replace_buffer_in_windows_safely): Add prototype.
18176 * window.c: Declare Qdelete_window static again. Move down
18177 declaration of select_count.
18178 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18179 (Fother_window): Move to window.el.
18180 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18181 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18182 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18184 (replace_buffer_in_windows): Implement by calling
18185 Qreplace_buffer_in_windows.
18186 (replace_buffer_in_all_windows): Remove with some functionality
18187 moved into replace_buffer_in_windows_safely.
18188 (replace_buffer_in_windows_safely): New function.
18189 (select_window_norecord, select_frame_norecord): Move in front
18190 of run_window_configuration_change_hook. Remove now obsolete
18192 (Fset_window_buffer): Rewrite doc-string.
18193 Call Qrecord_window_buffer.
18194 (keys_of_window): Move binding for other-window to window.el.
18196 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18198 * dispextern.h (struct image): Replace data member, whose int_val
18199 and ptr_val fields were not used by anything, with a single
18202 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18203 (gif_clear_image, gif_load, imagemagick_load_image)

18682 * gnutls.c: Use Emacs's memory allocators.
18683 Without this change, the gnutls library would invoke malloc etc.
18684 directly, which causes problems on non-SYNC_INPUT hosts, and which
18685 runs afoul of improving memory_full behavior. (Bug#8761)
18686 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18687 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18688 xfree instead of the default malloc, realloc, free.
18689 (Fgnutls_boot): No need to check for memory allocation failure,
18690 since xmalloc does that for us.
18692 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18693 * category.c (hash_get_category_set):
18694 * ccl.c (ccl_driver):
18695 * charset.c (Fdefine_charset_internal):
18696 * charset.h (struct charset.hash_index):
18697 * composite.c (get_composition_id, gstring_lookup_cache)
18698 (composition_gstring_put_cache):
18699 * composite.h (struct composition.hash_index):
18700 * dispextern.h (struct image.hash):
18701 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18702 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
18703 (hashfn_equal, hashfn_user_defined, make_hash_table)

18705 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18706 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18707 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18708 * image.c (make_image, search_image_cache, lookup_image)
18709 (xpm_put_color_table_h):
18710 * lisp.h (struct Lisp_Hash_Table):
18711 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18712 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18713 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18714 * alloc.c (allocate_vectorlike):
18715 Check for overflow in vector size calculations.
18716 * ccl.c (ccl_driver):
18717 Check for overflow when converting EMACS_INT to int.
18718 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18719 need to be updated by these changes.
18720 * fns.c (make_hash_table, maybe_resize_hash_table):
18721 Check for integer overflow with large hash tables.
18722 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18723 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18724 (SXHASH_REDUCE): New macro.
18725 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18726 Use it instead of discarding useful hash info with large hash values.
18727 (sxhash_float): New function.
18728 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18729 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18730 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18731 Rewrite to use FIXNUM_BITS, as this simplifies things.
18732 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18733 Adjust signatures to match updated version of code.
18734 (consing_since_gc): Now EMACS_INT, since a single hash table can
18735 use more than INT_MAX bytes.
18737 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18739 Make it possible to build with GCC-4.6+ -O2 -flto.
18741 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18743 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18745 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18746 Call minibuffer-inactive-mode.
18748 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18750 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18751 Update dependencies.
18753 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18755 * data.c (init_data): Remove code for UTS, this system is not
18758 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18760 Don't force ./temacs to start in terminal mode.
18762 * frame.c (make_initial_frame): Initialize faces in all cases, not
18763 only when CANNOT_DUMP is defined.
18764 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18766 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18768 * dispnew.c (add_window_display_history): Use const for the string
18769 pointer. Remove declaration, not needed.
18771 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18773 Use 'inline', not 'INLINE'.
18774 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18775 * alloc.c, fontset.c (INLINE): Remove.
18776 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18777 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18778 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18779 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18780 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18782 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18784 Make it possible to run ./temacs.
18786 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18787 syms_of_callproc does the same thing. Remove test for
18788 "initialized", do it in the caller.
18789 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18791 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18793 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18794 (read_minibuf): Use get_minibuffer.
18795 (syms_of_minibuf): Use DEFSYM.
18796 (Qmetadata): New var.
18797 * data.c (Qbuffer): Don't make it static.
18798 (syms_of_data): Use DEFSYM.
18800 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18802 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18803 (CCL_CODE_MIN): New macro.
18805 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18807 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18809 * eval.c (Qdebug): Now static.
18810 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18811 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18812 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18814 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18816 * image.c: Various fixes to ImageMagick code comments.
18817 (Fimagemagick_types): Doc fix.
18819 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18821 Minor fixes prompted by GCC 4.6.0 warnings.
18823 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18825 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18826 (x_clipboard_manager_save_all): Move extern decl to ...
18827 * xterm.h: ... here, so that it can be checked for consistency.
18829 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18831 * xselect.c (x_clipboard_manager_save_frame)
18832 (x_clipboard_manager_save_all): New functions.
18833 (Fx_clipboard_manager_save): Lisp function deleted.
18835 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18836 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18838 * xterm.h: Update prototype.
18840 2011-05-28 William Xu <william.xwl@gmail.com>
18842 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18843 exiting (Bug#8239).
18845 2011-05-28 Jim Meyering <meyering@redhat.com>
18847 Avoid a sign-extension bug in crypto_hash_function.
18848 * fns.c (to_uchar): Define.
18849 (crypto_hash_function): Use it to convert some newly-signed
18850 variables to unsigned, to avoid sign-extension bugs. For example,
18851 without this change, (md5 "truc") would evaluate to
18852 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18853 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18854 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18856 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18858 Integer overflow fixes.
18860 * dbusbind.c: Serial number integer overflow fixes.
18861 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18862 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18863 to hold a serial number that is too large for a fixnum.
18864 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18865 Check for serial numbers out of range. Decode any serial number
18866 that was so large that it became a float. (Bug#8722)
18868 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18869 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18870 Use XFASTINT rather than XUINT when numbers are nonnegative.
18871 (xd_append_arg, Fdbus_method_return_internal):
18872 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18873 arguments, check that Lisp number is nonnegative, rather than
18874 silently wrapping negative numbers around. (Bug#8722)
18875 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18878 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18880 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18882 ccl: Add integer overflow checks.
18883 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18884 (IN_INT_RANGE): New macros.
18885 (ccl_driver): Use them to check for integer overflow when
18886 decoding a CCL program. Many of the new checks are whether XINT (x)
18887 fits in int; it doesn't always, on 64-bit hosts. The new version
18888 doesn't catch all possible integer overflows, but it's an
18889 improvement. (Bug#8719)
18891 * alloc.c (make_event_array): Use XINT, not XUINT.
18892 There's no need for unsigned here.
18894 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18895 This follows up to the 2011-05-06 change that substituted uintptr_t
18896 for EMACS_INT. This case wasn't caught back then.
18898 Rework Fformat to avoid integer overflow issues.
18899 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18900 now (part of C89). Include <verify.h>.
18901 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18902 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18903 (Fformat): Avoid the prepass trying to compute sizes; it was only
18904 approximate and thus did not catch overflow reliably. Instead, walk
18905 through the format just once, formatting and computing sizes as we go,
18906 checking for integer overflow at every step, and allocating a larger
18907 buffer as needed. Keep track separately whether the format is
18908 multibyte. Keep only the most-recently calculated precision, rather
18909 than them all. Record whether each argument has been converted to
18910 string. Use EMACS_INT, not int, for byte and char and arg counts.
18911 Support field widths and precisions larger than INT_MAX. Avoid
18912 sprintf's undefined behavior with conversion specifications such as %#d
18913 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18914 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18915 formatting out-of-range floating point numbers with int
18916 formats. (Bug#8668)
18918 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18920 * data.c: Avoid integer truncation in expressions involving floats.
18921 * data.c: Include <intprops.h>.
18922 (arith_driver): When there's an integer overflow in an expression
18923 involving floating point, convert the integers to floating point
18924 so that the resulting value does not suffer from catastrophic
18925 integer truncation. For example, on a 64-bit host (* 4
18926 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18927 Do not rely on undefined behavior after integer overflow.
18929 merge count_size_as_multibyte, parse_str_to_multibyte
18930 * character.c, character.h (count_size_as_multibyte):
18931 Rename from parse_str_to_multibyte; all uses changed.
18932 Check for integer overflow.
18933 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18934 since it's now a duplicate of the other. This is more of
18935 a character than a buffer op, so better that it's in character.c.
18936 * fns.c, print.c: Adjust to above changes.
18938 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18940 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18942 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18944 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18945 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18946 (x_clipboard_manager_save): Now static.
18947 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18949 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18950 (crypto_hash_function): Now static.
18951 Fix pointer signedness problems. Avoid unnecessary initializations.
18953 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18955 * termhooks.h (Vselection_alist): Make it terminal-local.
18957 * terminal.c (create_terminal): Initialize it.
18959 * xselect.c: Support for clipboard managers.
18960 (Vselection_alist): Move to termhooks.h as terminal-local var.
18961 (LOCAL_SELECTION): New macro.
18962 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18963 (symbol_to_x_atom): Remove gratuitous arg.
18964 (x_handle_selection_request, lisp_data_to_selection_data)
18965 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18966 (x_own_selection, x_get_local_selection, x_convert_selection):
18967 New arg, specifying work frame. Use terminal-local Vselection_alist.
18968 (some_frame_on_display): Delete unused function.
18969 (Fx_own_selection_internal, Fx_get_selection_internal)
18970 (Fx_disown_selection_internal, Fx_selection_owner_p)
18971 (Fx_selection_exists_p): New optional frame arg.
18972 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18973 (x_handle_selection_clear): Don't treat other terminals with the
18974 same keyboard specially. Use the terminal-local Vselection_alist.
18975 (x_clear_frame_selections): Use Frun_hook_with_args.
18977 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18979 * xterm.h: Add support for those atoms.
18981 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18983 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18984 (converted_selections, conversion_fail_tag): New global variables.
18985 (x_selection_request_lisp_error): Free the above.
18986 (x_get_local_selection): Remove unnecessary code.
18987 (x_reply_selection_request): Args changed; handle arbitrary array
18988 of converted selections stored in converted_selections.
18989 Separate the XChangeProperty and SelectionNotify steps.
18990 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18991 (x_convert_selection): New function.
18992 (x_handle_selection_event): Simplify.
18993 (x_get_foreign_selection): Don't ignore incoming requests while
18994 waiting for an answer; this will fail when we implement
18995 SAVE_TARGETS, and seems unnecessary anyway.
18996 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18997 (Vx_sent_selection_functions): Doc fix.
18999 2011-05-26 Leo Liu <sdl.web@gmail.com>
19001 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19003 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19005 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19007 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19008 for fringe update if it has periodic bitmap.
19009 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19010 and fringe_bitmap_periodic_p.
19012 * fringe.c (get_fringe_bitmap_data): New function.
19013 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19014 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19015 row. Mark glyph row for fringe update if periodicity changed.
19017 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19018 for fringe update unless it has periodic bitmap.

19039 Remove macros that are defined and never used.
19040 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19042 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19044 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19045 (Fx_get_selection_internal): Minor cleanup.

19071 report_file_error introduced by the change from 2011-05-07.
19073 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19075 * systime.h (Time): Define only if emacs is defined.
19076 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19077 where the include path doesn't have X11/X.h by default. See
19078 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19080 2011-05-20 Kenichi Handa <handa@m17n.org>
19082 * composite.c (find_automatic_composition): Fix previous change.
19084 2011-05-20 Glenn Morris <rgm@gnu.org>

19095 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19096 (lisp): Set the order to that of loadup.el.
19097 (shortlisp): Make it a copy of $lisp.
19098 (SOME_MACHINE_LISP): Remove.

19104 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19105 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19106 (find_automatic_composition): Mostly rewrite for efficiency.
19108 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19110 * makefile.w32-in: Update dependencies.
19112 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19114 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19115 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19117 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19119 Fix some integer overflow issues, such as string length overflow.
19121 * insdel.c (count_size_as_multibyte): Check for string overflow.
19123 * character.c (lisp_string_width): Check for string overflow.
19124 Use EMACS_INT, not int, for string indexes and lengths; in
19125 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19126 the resulting string length overflows an EMACS_INT; instead,
19127 report a string overflow if no precision given. When checking for
19128 precision exhaustion, use a check that cannot possibly have
19129 integer overflow. (Bug#8675)
19130 * character.h (lisp_string_width): Adjust to new signature.
19132 * alloc.c (string_overflow): New function.
19133 (Fmake_string): Use it. This doesn't change behavior, but saves
19134 a few bytes and will simplify future changes.
19135 * character.c (string_escape_byte8): Likewise.
19136 * lisp.h (string_overflow): New decl.
19138 Fixups, following up to the user-interface timestamp change.
19139 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19140 for UI timestamps, instead of unsigned long.
19141 * msdos.c (mouse_get_pos): Likewise.
19142 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19143 * w32gui.h (Time): Define by including "systime.h" rather than by
19144 declaring it ourselves. (Bug#8664)
19146 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19147 * image.c (clear_image_cache): Likewise.
19149 * term.c (term_mouse_position): Don't assume time_t wraparound.
19151 Be more systematic about user-interface timestamps.
19152 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19153 and sometimes 'EMACS_UINT', to represent these timestamps.
19154 This change causes it to use 'Time' uniformly, as that's what X uses.
19155 This makes the code easier to follow, and makes it easier to catch
19156 integer overflow bugs such as Bug#8664.
19157 * frame.c (Fmouse_position, Fmouse_pixel_position):
19158 Use Time, not unsigned long, for user-interface timestamps.
19159 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19160 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19161 * keyboard.h (last_event_timestamp): Likewise.
19162 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19163 * menu.h (xmenu_show): Likewise.
19164 * term.c (term_mouse_position): Likewise.
19165 * termhooks.h (struct input_event.timestamp): Likewise.
19166 (struct terminal.mouse_position_hook): Likewise.
19167 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19168 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19169 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19170 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19171 what it was before.
19172 * menu.h, termhooks.h: Include "systime.h", for Time.
19174 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19175 Don't assume that the difference between two unsigned long values
19176 can fit into an integer. At this point, we know button_down_time
19177 <= event->timestamp, so the difference must be nonnegative, so
19178 there's no need to cast the result if double-click-time is
19179 nonnegative, as it should be; check that it's nonnegative, just in
19180 case. This bug is triggered when events are more than 2**31 ms
19181 apart (about 25 days). (Bug#8664)
19183 * xselect.c (last_event_timestamp): Remove duplicate decl.
19184 (x_own_selection): Remove needless cast to unsigned long.
19186 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19187 that always fit in int. Use a sentinel instead of a counter, to
19188 avoid a temp and to allay GCC's concerns about possible int overflow.
19189 * frame.h (struct frame): Use int for menu_bar_items_used
19190 instead of EMACS_INT, since it always fits in int.
19192 * menu.c (grow_menu_items): Check for int overflow.
19194 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19196 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19197 Before, the code was not consistent. These values cannot exceed
19198 2**31 - 1 so there's no need to make them unsigned.
19199 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19200 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19201 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19203 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19205 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19206 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19207 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19208 presumably because the widths might not match.
19210 * window.c (size_window): Avoid needless test at loop start.
19212 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19214 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19216 2011-05-12 Drew Adams <drew.adams@oracle.com>
19218 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19220 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19222 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19223 `width' to `bar_area_x' and `bar_area_width', respectively.
19224 (x_scroll_run): Take account of fringe background extension.
19226 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19227 Rename local vars `left' and `width' to `bar_area_x' and
19228 `bar_area_width', respectively.
19229 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19230 background extension.
19232 2011-05-10 Jim Meyering <meyering@redhat.com>
19234 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19236 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19238 * image.c (Finit_image_library): Return t for built-in image types,
19239 like pbm and xbm. (Bug#8640)
19241 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19243 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19245 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19247 * w32console.c (Fset_screen_color): Doc fix.
19248 (Fget_screen_color): New function.
19249 (syms_of_ntterm): Defsubr it.
19251 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19252 unlink the temporary file if Fcall_process didn't create it in the
19254 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19255 child process will be redirected to a file specified with `:file'.
19256 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19257 cue to call_process_cleanup not to close that handle.
19259 2011-05-07 Ben Key <bkey76@gmail.com>
19261 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19262 one of two shell specific rules, either bootstrap-temacs-CMD or
19263 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19264 to the previous implementation of the bootstrap-temacs rule.
19265 The bootstrap-temacs-CMD rule is similar to the previous
19266 implementation of the bootstrap-temacs rule except that it
19267 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19270 These changes, along with some changes to nt/configure.bat,
19271 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19272 earlier fix to add support for --cflags and --ldflags options
19273 that include quotes so that it works whether make uses cmd or
19276 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19278 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19279 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19281 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19282 a string. Handle both cases.
19283 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19284 (Fdbus_register_method): Use Qinvalid_function.
19286 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19288 * makefile.w32-in: Update dependencies.
19289 (LISP_H): Add inttypes.h and stdin.h.
19290 (PROCESS_H): Add unistd.h.
19292 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19294 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19295 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19297 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19299 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19301 * term.c (vfatal): Remove stray call to va_end.
19302 It's not needed and the C Standard doesn't allow it here anyway.
19304 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19305 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19307 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19310 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19312 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19314 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19316 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19318 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19320 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19321 * charset.c (Fdefine_charset_internal): Don't initialize
19322 charset.code_space[15]. The value was garbage, on hosts with
19323 32-bit int (Bug#8600).
19325 * lread.c (read_integer): Be more consistent with string-to-number.
19326 Use string_to_number to do the actual conversion; this avoids
19327 rounding errors and fixes some other screwups. Without this fix,
19328 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19329 (digit_to_number): Move earlier, for benefit of read_integer.
19330 Return -1 if the digit is out of range for the base, -2 if it is
19331 not a digit in any supported base. (Bug#8602)
19333 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19335 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19336 to match comment at start of function. This also removes a
19337 GCC warning about overflow in a 32+64-bit port.
19339 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19341 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19342 Reported by Stefan Monnier in
19343 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19344 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19345 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19347 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19348 (EMACS_UINTPTR): Likewise, with uintptr_t.
19350 * lisp.h: Prefer 64-bit EMACS_INT if available.
19351 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19352 on 32-bit hosts that have 64-bit int, so that they can access
19354 However, temporarily disable this change unless the temporary
19355 symbol WIDE_EMACS_INT is defined.
19357 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19359 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19360 This removes an assumption that EMACS_INT and long are the same
19361 width as pointers. The assumption is true for Emacs porting targets
19362 now, but we want to make other targets possible.
19363 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19364 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19365 In the rest of the code, change types of integers that hold casted
19366 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19367 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19368 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19369 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19370 No need to cast type when ORing.
19371 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19372 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19373 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19374 assume EMACS_INT is the same width as char *.
19375 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19376 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19377 Remove no-longer-needed casts.
19378 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19379 (xg_tool_bar_help_callback, xg_make_tool_item):
19380 Use EMACS_INTPTR to hold an integer
19381 that will be cast to void *; this can avoid a GCC warning
19382 if EMACS_INT is not the same width as void *.
19383 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19384 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19385 (current_message_1, set_message_1):
19386 Use a local to convert to proper width without a cast.
19387 * xmenu.c (dialog_selection_callback): Likewise.
19389 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19390 Also, don't assume VALBITS / RAND_BITS is less than 5,
19391 and don't rely on undefined behavior when shifting a 1 left into
19393 * lisp.h (get_random): Change signature to match.
19395 * lread.c (hash_string): Use size_t, not int, for hash computation.
19396 Normally we prefer signed values; but hashing is special, because
19397 it's better to use unsigned division on hash table sizes so that
19398 the remainder is nonnegative. Also, size_t is the natural width
19399 for hashing into memory. The previous code used 'int', which doesn't
19400 retain enough info to hash well into very large tables.
19401 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19403 * dbusbind.c: Don't possibly lose pointer info when converting.
19404 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19405 Use XPNTR rather than XHASH, so that the high-order bits of
19406 the pointer aren't lost when converting through void *.
19408 * eval.c (Fautoload): Don't double-shift a pointer.
19410 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19412 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19414 * gnutls.c (DEF_GNUTLS_FN):
19415 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19417 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19419 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19422 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19424 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19425 New version that can reserve upto 2GB of heap space.
19427 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19429 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19431 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19433 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19434 `gnutls_certificate_set_x509_key_file'.
19436 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19438 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19439 Update dependencies.
19441 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19443 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19444 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19445 Remove unused parameter `fildes'.
19446 * process.c (read_process_output, send_process): Don't pass it.
19448 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19450 Fix previous change: the library cache is defined in w32.c.
19451 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19452 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19454 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19456 Implement dynamic loading of GnuTLS on Windows.
19458 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19459 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19460 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19463 * gnutls.c (Qgnutls_dll): Define.
19464 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19465 (gnutls_*): Declare function pointers.
19466 (init_gnutls_functions): New function to initialize function pointers.
19467 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19468 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19469 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19470 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19471 (emacs_gnutls_write, emacs_gnutls_read)
19472 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19473 (Fgnutls_available_p): New function.
19474 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19475 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19476 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19478 * image.c: Include w32.h.
19479 (Vimage_type_cache): Delete.
19480 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19481 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19482 (w32_delayed_load): Move to w32.c.
19484 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19486 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19487 (w32_delayed_load): Move from image.c. When loading a library, record
19488 its filename in the :loaded-from property of the library id.
19489 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19490 Initialize and staticpro them.
19491 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19493 * process.c: Include lisp.h before w32.h, not after.
19494 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19495 instead of gnutls_record_check_pending.
19497 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19499 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19501 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19502 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19505 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19507 * xterm.c (x_set_frame_alpha): Do not set property on anything
19508 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19510 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19512 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19514 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19516 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19517 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
19518 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

19523 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19524 (Qgnutls_bootprop_callbacks_verify): Make static.
19526 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>

19532 Move after wait_for_termination_1.
19534 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19536 * sysdep.c (interruptible_wait_for_termination): New function
19537 which is like wait_for_termination, but allows keyboard
19540 * callproc.c (Fcall_process): Add (:file "file") as an option for
19542 (Fcall_process_region): Ditto.
19544 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19546 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19547 rather than `XVECTOR (FOO)->size'.
19549 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19550 inttypes.h, as a gnulib replacement is used if it not available in
19553 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19555 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19556 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19557 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19559 * coding.c (coding_alloc_by_realloc): Error out if destination
19560 will grow beyond MOST_POSITIVE_FIXNUM.
19561 (decode_coding_emacs_mule): Abort if there isn't enough place in
19562 charbuf for the composition carryover bytes. Reserve an extra
19563 space for up to 2 characters produced in a loop.
19564 (decode_coding_iso_2022): Abort if there isn't enough place in
19565 charbuf for the composition carryover bytes.
19567 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19569 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19570 aborting when %lld or %lll format is passed.
19571 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19572 %llo or %llx format is passed. (Bug#8545)
19574 * window.c (window_scroll_line_based): Use a marker instead of
19575 simple variables to record original value of point. (Bug#7952)
19577 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19578 produced by %s or %c overflows available buffer space. (Bug#8545)
19580 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19582 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19583 (SIZE_MAX): Move defn after all includes, as they might #define it.
19585 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19587 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19589 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19591 * keyboard.c (Qdelayed_warnings_hook): Define.
19592 (command_loop_1): Run `delayed-warnings-hook'
19593 if Vdelayed_warnings_list is non-nil.
19594 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19595 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19597 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19599 * doprnt.c (doprnt): Don't return value smaller than the buffer
19600 size if the message was truncated. (Bug#8545).
19602 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19604 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19605 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19607 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19609 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19611 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19613 * makefile.w32-in: Update dependencies.
19615 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19617 Improve `doprnt' and its usage. (Bug#8545)
19618 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19619 `format_end'. Remove support for %l as a conversion specifier.
19620 Don't use xrealloc. Improve diagnostics when the %l size modifier
19621 is used. Update the commentary.
19623 * eval.c (verror): Simplify calculation of size_t.
19625 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19628 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19630 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19633 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19635 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19636 This makes this file independent of the recent pseudovector change.
19638 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19640 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19642 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19643 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19644 Remove unused local.
19645 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19647 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19648 GCC 4.6.0 optimizes based on type-based alias analysis.
19649 For example, if b is of type struct buffer * and v of type struct
19650 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19651 != &v->size, and therefore "v->size = 1; b->size = 2; return
19652 v->size;" must therefore return 1. This assumption is incorrect
19653 for Emacs, since it type-puns struct Lisp_Vector * with many other
19654 types. To fix this problem, this patch adds a new type struct
19655 vectorlike_header that documents the constraints on layout of vectors
19656 and pseudovectors, and helps optimizing compilers not get fooled
19657 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19658 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19659 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19661 (XSETPVECTYPE): Rewrite in terms of new macro.
19662 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19663 This is a bit clearer, and further avoids the possibility of
19664 undesirable aliasing.
19665 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19666 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19667 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19668 since Lisp_Subr is a special case (no "next" field).
19669 (ASIZE): Now uses header.size rather than size.
19670 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19671 to avoid the hassle of writing XVECTOR (foo)->header.size.
19672 (struct vectorlike_header): New type.
19673 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19674 object, to help avoid aliasing.
19675 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19676 (SUBRP): Likewise, since Lisp_Subr is a special case.
19677 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19678 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19679 (struct Lisp_Hash_Table): Combine first two members into a single
19680 struct vectorlike_header member. All uses of "size" and "next" members
19681 changed to be "header.size" and "header.next".
19682 * buffer.h (struct buffer): Likewise.
19683 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19684 * frame.h (struct frame): Likewise.
19685 * process.h (struct Lisp_Process): Likewise.
19686 * termhooks.h (struct terminal): Likewise.
19687 * window.c (struct save_window_data, struct saved_window): Likewise.
19688 * window.h (struct window): Likewise.
19689 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19690 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19691 * buffer.c (init_buffer_once): Likewise.
19692 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19694 * process.c (Fformat_network_address): Use local var for size,
19697 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19699 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19700 * data.c (atof): Remove decl; no longer used or needed.
19701 (digit_to_number): Move to lread.c.
19702 (Fstring_to_number): Use new string_to_number function, to be
19703 consistent with how the Lisp reader treats infinities and NaNs.
19704 Do not assume that floating-point numbers represent EMACS_INT
19705 without losing information; this is not true on most 64-bit hosts.
19706 Avoid double-rounding errors, by insisting on integers when
19707 parsing non-base-10 numbers, as the documentation specifies.
19708 * lisp.h (string_to_number): New decl, replacing ...
19709 (isfloat_string): Remove.
19710 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19711 (read1): Do not accept +. and -. as integers; this
19712 appears to have been a coding error. Similarly, do not accept
19713 strings like +-1e0 as floating point numbers. Do not report
19714 overflow for integer overflows unless the base is not 10 which
19715 means we have no simple and reliable way to continue.
19716 Break out the floating-point parsing into a new
19717 function string_to_number, so that Fstring_to_number parses
19718 floating point numbers consistently with the Lisp reader.
19719 (digit_to_number): Move here from data.c. Make it static inline.
19720 (E_CHAR, EXP_INT): Remove, replacing with ...
19721 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19722 (string_to_number): New function, replacing isfloat_string.
19723 This function checks for valid syntax and produces the resulting
19724 Lisp float number too. Rework it so that string-to-number
19725 no longer mishandles examples like "1.0e+". Use strtoumax,
19726 so that overflow for non-base-10 numbers is reported only when
19727 there's no portable and simple way to convert to floating point.
19729 * textprop.c (set_text_properties_1): Rewrite for clarity,
19730 and to avoid GCC warning about integer overflow.
19732 * intervals.h (struct interval): Use EMACS_INT for members
19733 where EMACS_UINT might cause problems. See
19734 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19735 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19736 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19738 (offset_intervals): Tell GCC not to worry about length overflow
19739 when negating a negative length.
19741 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19742 (overrun_check_free): Likewise.
19744 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19745 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19748 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19749 (gnutls_make_error): Rename local to avoid shadowing.
19750 (gnutls_emacs_global_deinit): ifdef out; not used.
19751 (Fgnutls_boot): Use const for pointer to readonly storage.
19752 Comment out unused local. Fix pointer signedness problems.
19754 * lread.c (openp): Don't stuff size_t into an 'int'.
19755 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19756 about possible signed overflow.
19758 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19759 (GDK_KEY_g): Don't define if already defined.
19760 (xg_prepare_tooltip): Avoid pointer signedness problem.
19761 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19763 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19764 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19766 * xfns.c (Fx_window_property): Simplify a bit,
19767 to make a bit faster and to avoid GCC 4.6.0 warning.
19768 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19770 * fns.c (internal_equal): Don't assume size_t fits in int.
19772 * alloc.c (compact_small_strings): Tighten assertion a little.
19774 Replace pEd with more-general pI, and fix some printf arg casts.
19775 * lisp.h (pI): New macro, generalizing old pEd macro to other
19776 conversion specifiers. For example, use "...%"pI"d..." rather
19777 than "...%"pEd"...".
19778 (pEd): Remove. All uses replaced with similar uses of pI.
19779 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19780 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19781 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19782 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19783 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19784 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19785 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19787 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19788 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19789 * print.c (safe_debug_print, print_object): Likewise.
19790 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19792 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19793 avoiding the 0 flag, which is not portable.
19794 * process.c (Fmake_network_process): Use pI to avoid cast.
19795 * region-cache.c (pp_cache): Likewise.
19796 * xdisp.c (decode_mode_spec): Likewise.
19797 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19798 behavior on 64-bit hosts with printf arg.
19799 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19800 (x_stop_queuing_selection_requests): Likewise.
19801 (x_get_window_property): Don't truncate byte count to an 'int'
19804 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19805 here, since it parses constructs like leading '-' and spaces,
19806 which are not wanted; and it overflows with large numbers.
19807 Instead, simply match F[0-9]+, which is what is wanted anyway.
19809 * alloc.c: Remove unportable assumptions about struct layout.
19810 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19811 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19812 (allocate_vectorlike, make_pure_vector): Use the new macros,
19813 plus offsetof, to remove unportable assumptions about struct layout.
19814 These assumptions hold on all porting targets that I know of, but
19815 they are not guaranteed, they're easy to remove, and removing them
19816 makes further changes easier.
19818 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19819 This doesn't fix a bug but makes the code clearer.
19820 (string_overrun_cookie): Now const. Use initializers that
19821 don't formally overflow signed char, to avoid warnings.
19822 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19823 can cause Emacs to crash when string overrun checking is enabled.
19824 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19825 multiple of sizeof (EMACS_INT); it need not be, if
19826 alignof(EMACS_INT) < sizeof (EMACS_INT).
19827 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19829 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19836 supposed to be handshaking. (Bug#8556)
19837 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19839 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

19845 matches the current signal symbol.
19847 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19849 * alloc.c (check_sblock, check_string_bytes)
19850 (check_string_free_list): Convert to standard C.
19852 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19854 * w32.c (emacs_gnutls_push): Fix typo.
19856 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19858 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19859 "cast to pointer from integer of different size".
19861 Improve doprnt and its use in verror. (Bug#8545)
19862 * doprnt.c (doprnt): Document the set of format control sequences
19863 supported by the function. Use SAFE_ALLOCA instead of always
19866 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19867 is one byte too soon. Don't use xrealloc; instead xfree and
19870 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19872 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19875 * gnutls.c: Renamed global_initialized to
19876 gnutls_global_initialized. Added internals for the
19877 :verify-hostname-error, :verify-error, and :verify-flags
19878 parameters of `gnutls-boot' and documented those parameters in the
19879 docstring. Start callback support.
19880 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19881 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19882 on error. Return error code.
19883 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19884 (emacs_gnutls_read): Likewise.
19885 (Fgnutls_boot): Return handshake error code.
19886 (emacs_gnutls_handle_error): New function.
19887 (wsaerror_to_errno): Likewise.

19893 (emacs_gnutls_push): Likewise.
19895 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19897 * process.c (wait_reading_process_output): Check if GnuTLS
19898 buffered some data internally if no FDs are set for TLS
19901 * makefile.w32-in (OBJ2): Add gnutls.$(O).

19908 display_replaced_before_p argument into display_replaced_p, to
19909 make it consistent with the commentary. Fix typos in the

19942 changes in globals.h immediately force recompilation.
19943 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19944 $(CURDIR)/s/ms-w32.h.

19949 <char-direction-table>: Deleted.
19951 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19953 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19954 * doprnt.c: Include limits.h.
19955 (SIZE_MAX): New macro.
19956 (doprnt): Return a size_t value. 2nd arg is now size_t.
19957 Many local variables are now size_t instead of int or unsigned.
19958 Improve overflow protection. Support `l' modifier for integer
19959 conversions. Support %l conversion. Don't assume an EMACS_INT
19960 argument for integer conversions and for %c.
19962 * lisp.h (doprnt): Restore prototype.
19964 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19965 $(SRC)/character.h.
19967 * Makefile.in (base_obj): Add back doprnt.o.
19969 * deps.mk (doprnt.o): Add back prerequisites.
19970 (callint.o): Depend on character.h.

20437 worth the hassle of breaking this out.
20439 * xterm.c: Make symbols static if they're not exported.
20440 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
20441 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

20540 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
20541 * lisp.h: Remove these decls.
20543 * buffer.c (buffer_count): Remove unused var.
20545 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

20547 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20548 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20549 exported only to the debugger.

20552 * atimer.h (run_all_atimers): Remove; not exported.
20554 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20555 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20556 was inaccessible from Lisp.
20557 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20558 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20560 alloc.c: Import and export fewer symbols, and remove unused items.
20561 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20563 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20564 it's not optimized away by whole-program optimization.

20567 Declare only if BYTE_MARK_STACK.

20576 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20577 (mark_backtrace): Define only if BYTE_MARK_STACK.
20578 * xdisp.c (message_enable_multibyte): Now static.
20580 Declare Lisp_Object Q* variables to be 'static' if not exported.
20581 This makes it easier for human readers (and static analyzers)
20582 to see whether these variables are used from other modules.
20583 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20584 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

20593 Remove decls of unexported vars.
20594 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20596 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20598 Make Emacs functions such as Fatom 'static' by default.
20599 This makes it easier for human readers (and static analyzers)
20600 to see whether these functions can be called from other modules.
20601 DEFUN now defines a static function. To make the function external
20602 so that it can be used in other C modules, use the new macro DEFUE.
20603 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20604 (Finit_image_library):
20605 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20606 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20607 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20608 Remove decls, since these functions are now static.
20609 (Funintern, Fget_internal_run_time): New decls, since these functions
20610 were already external.
20612 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20613 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20619 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20620 Mark functions with DEFUE instead of DEFUN,
20621 if they are used in other modules.
20622 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20623 decls for now-static functions.
20624 * buffer.h (Fdelete_overlay): Remove decl.
20625 * callproc.c (Fgetenv_internal): Mark as internal.
20626 * composite.c (Fremove_list_of_text_properties): Remove decl.

20632 (Funintern): Remove extern decl; now in .h file where it belongs.
20633 * fileio.c (Fmake_symbolic_link): New forward static decl.
20634 * image.c (Finit_image_library): New forward static decl.
20635 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20636 * intervals.h (Fprevious_property_change):
20637 (Fremove_list_of_text_properties): Remove decls.
20638 * keyboard.c (Fthis_command_keys): Remove decl.
20639 (Fcommand_execute): New forward static decl.
20640 * keymap.c (Flookup_key): New forward static decl.
20641 (Fcopy_keymap): Now static.
20642 * keymap.h (Flookup_key): Remove decl.
20643 * process.c (Fget_process): New forward static decl.
20644 (Fprocess_datagram_address): Mark as internal.

20655 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
20657 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20660 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20662 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20663 when at ZV. (Bug#8487)
20665 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20667 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20671 * termcap.c (tgetent): Likewise.
20672 * xfns.c (x_default_font_parameter): Likewise.
20673 * xsettings.c (read_and_apply_settings): Likewise.
20675 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20676 (overrun_check_free): Protoize.
20678 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20680 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20681 since callers should never pass a negative size.
20682 Change the signature to match that of plain 'read' and 'write'; see
20683 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20684 * lisp.h: Update prototypes of emacs_write and emacs_read.
20686 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20688 * xdisp.c (redisplay_window): Don't try to determine the character
20689 position of the scroll margin if the window start point w->startp
20690 is outside the buffer's accessible region. (Bug#8468)
20692 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20694 Fix write-region and its subroutines for buffers > 2GB.
20695 * fileio.c (a_write, e_write): Modify declaration of arguments and
20696 local variables to support buffers larger than 2GB.
20697 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20699 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20700 argument, local variables, and return value.
20702 * lisp.h: Update prototypes of emacs_write and emacs_read.
20704 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20706 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20708 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20710 Fix more problems found by GCC 4.6.0's static checks.
20712 * xdisp.c (vmessage): Use a better test for character truncation.
20714 * charset.c (load_charset_map): <, not <=, for optimization,
20715 and to avoid potential problems with integer overflow.
20716 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20717 * casetab.c (set_identity, shuffle): Likewise.
20718 * editfns.c (Fformat): Likewise.
20719 * syntax.c (skip_chars): Likewise.
20721 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20722 This also lets GCC 4.6.0 generate slightly better loop code.
20724 * callint.c (Fcall_interactively): <, not <=, for optimization.
20725 (Fcall_interactively): Count the number of arguments produced,
20726 not the number of arguments given. This is simpler and lets GCC
20727 4.6.0 generate slightly better code.
20729 * ftfont.c: Distingish more carefully between FcChar8 and char.
20730 The previous code passed unsigned char * to a functions like
20731 strlen and xstrcasecmp that expect char *, which does not
20732 conform to the C standard.
20733 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20734 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20735 char * when the C standard requires it.
20737 * keyboard.c (read_char): Remove unused var.
20739 * eval.c: Port to Windows vsnprintf (Bug#8435).
20740 Include <limits.h>.
20741 (SIZE_MAX): Define if the headers do not.
20742 (verror): Do not give up if vsnprintf returns a negative count.
20743 Instead, grow the buffer. This ports to Windows vsnprintf, which
20744 does not conform to C99. Problem reported by Eli Zaretskii.
20745 Also, simplify the allocation scheme, by avoiding the need for
20746 calling realloc, and removing the ALLOCATED variable.
20748 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20750 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20751 But keep the doprint source code for now, as we might revamp it
20752 and use it again (Bug#8435).
20753 * lisp.h (doprnt): Remove.
20754 * Makefile.in (base_obj): Remove doprnt.o.
20755 * deps.mk (doprnt.o): Remove.
20757 error: Print 32- and 64-bit integers portably (Bug#8435).
20758 Without this change, on typical 64-bit hosts error ("...%d...", N)
20759 was used to print both 32- and 64-bit integers N, which relied on
20760 undefined behavior.
20761 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20762 * lisp.h (error, verror): Mark as printf-like functions.
20763 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20764 Report overflow in size calculations when allocating printf buffer.
20765 Do not truncate output string at its first null byte.
20766 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20767 Truncate the output at a character boundary, since vsnprintf does not
20769 * charset.c (check_iso_charset_parameter): Convert internal
20770 character to string before calling 'error', since %c now has the
20772 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20773 overflow when computing char to be passed to 'error'. Do not
20774 pass Lisp_Object to 'error'; pass the integer instead.
20775 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20776 formatted with plain %d.
20778 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20780 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20782 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20784 * xterm.c (x_catch_errors): Remove duplicate declaration.
20786 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20788 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20790 2011-04-10 Jim Meyering <meyering@redhat.com>
20792 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20793 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20794 return ssize_t not "int", and use size_t as the buffer length.
20795 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20796 * gnutls.h: Update declarations.
20797 * process.c (read_process_output): Use ssize_t, to match.
20798 (send_process): Likewise.
20800 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20802 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20804 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20806 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20807 Use unsigned char, to match FcChar8 type definition.
20809 * xterm.c (handle_one_xevent):
20810 * xmenu.c (create_and_show_popup_menu):
20811 * xselect.c (x_decline_selection_request)
20812 (x_reply_selection_request): Avoid type-punned deref of X events.
20814 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20816 Fix some uses of `int' instead of EMACS_INT.
20817 * search.c (string_match_1, fast_string_match)
20818 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20819 (scan_buffer, find_next_newline_no_quit)
20820 (find_before_next_newline, search_command, Freplace_match)
20821 (Fmatch_data): Make some `int' variables be EMACS_INT.
20823 * xdisp.c (display_count_lines): 3rd argument and return value now
20824 EMACS_INT. All callers changed.
20825 (pint2hrstr): Last argument is now EMACS_INT.
20827 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20828 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

20846 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20847 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20849 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

20870 instead of using internal_with_output_to_temp_buffer.
20871 (Qhelp_form_show): New var.
20872 (syms_of_keyboard): Use DEFSYM macro.
20874 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20887 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20889 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20891 Fix more problems found by GCC 4.6.0's static checks.
20893 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

20897 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20899 * xdisp.c (vmessage): Mark as a printf-like function.
20901 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20908 to system-supplied API.
20910 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20912 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20913 This avoids several warnings with gcc -Wstrict-overflow.
20914 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20915 directly, rather than having caller test rule sign. This avoids
20916 some unnecessary tests.
20917 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20918 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20919 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20921 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20922 (xfont_open): Avoid unnecessary tests.
20924 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20926 * composite.h, composite.c (composition_gstring_put_cache):
20927 Use EMACS_INT, not int, for length.
20929 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20930 breaking out part of COMPOSITION_DECODE_RULE.
20931 (COMPOSITION_DECODE_RULE): Use it.
20932 * composite.c (get_composition_id): Remove unused local vars,
20933 by using the new macro.
20935 * textprop.c (set_text_properties_1): Change while to do-while,
20936 since the condition is always true at first.
20938 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20939 (interval_deletion_adjustment): Return unsigned value.
20942 * process.c (list_processes_1, create_pty, read_process_output):
20943 (exec_sentinel): Remove vars that were set but not used.
20944 (create_pty): Remove unnecessary "volatile"s.
20945 (Fnetwork_interface_info): Avoid possibility of int overflow.
20946 (read_process_output): Do adaptive read buffering even if carryover.
20947 (read_process_output): Simplify nbytes computation if buffered.

20958 * print.c (print_error_message): Avoid int overflow.
20960 * font.c (font_list_entities): Redo for clarity,
20961 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20963 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20964 (font_score): Avoid potential overflow in diff calculation.
20966 * fns.c (substring_both): Remove var that is set but not used.
20967 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20969 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20971 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20972 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20973 can always succeed if overflow has undefined behavior.
20975 * search.c (boyer_moore, wordify): Remove vars set but not used.
20976 (wordify): Omit three unnecessary tests.
20978 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20979 All callers changed. This avoids the need for an unused var.
20981 * casefiddle.c (casify_region): Remove var that is set but not used.
20983 * dired.c (file_name_completion): Remove var that is set but not used.
20985 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20987 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20988 (Finsert_file_contents): Remove unnecessary code checking fd.
20990 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20991 Check for integer overflow on size calculations.
20993 * buffer.c (Fprevious_overlay_change): Remove var that is set
20996 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20997 Remove vars that are set but not used.
20998 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20999 (timer_check_2): Mark vars as initialized.
21001 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21003 * image.c (lookup_image): Remove var that is set but not used.
21004 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21006 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21007 that are set but not used.
21009 * xfns.c (make_invisible_cursor): Don't return garbage
21010 if XCreateBitmapFromData fails (Bug#8410).
21012 * xselect.c (x_get_local_selection, x_handle_property_notify):
21013 Remove vars that are set but not used.
21015 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21016 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21018 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21019 Remove var that is set but not used.
21020 (scroll_bar_windows_size): Now size_t, not int.
21021 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21022 Check for overflow.
21024 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21025 (map_tty_color) [!defined MSDOS]: Likewise.
21027 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21029 * coding.c: Remove vars that are set but not used.
21030 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21031 All callers changed.
21032 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21033 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21034 (decode_coding_charset): Remove vars that are set but not used.
21036 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21037 that is set but not used.
21039 * print.c (print_object): Remove var that is set but not used.
21041 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21042 The gnulib version avoids calling malloc in the usual case,
21043 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21044 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21045 * filelock.c (current_lock_owner): Likewise.
21046 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21047 * sysdep.c: Include allocator.h, careadlinkat.h.
21048 (emacs_no_realloc_allocator): New static constant.
21049 (emacs_readlink): New function.
21050 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21051 ../lib/careadlinkat.h.
21053 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21055 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21056 first non-nil return value).
21058 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21060 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21061 if not defined (Bug#8403).
21063 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21065 * xdisp.c (display_count_lines): Remove parameter `start',
21066 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21067 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21068 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21070 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21071 and thereabouts. All callers changed.
21072 (get_per_char_metric): Remove parameter `f', unused since
21073 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21075 2011-04-02 Jim Meyering <meyering@redhat.com>
21077 do not dereference NULL upon failed strdup
21078 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21079 (ns_get_family): Likewise.
21081 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21083 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21085 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21087 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21090 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21092 Add lexical binding.
21094 * window.c (Ftemp_output_buffer_show): New fun.
21095 (Fsave_window_excursion):
21096 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21098 * lread.c (lisp_file_lexically_bound_p): New function.

21103 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21105 (syms_of_lread): Declare `lexical-binding'.
21107 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21109 * keyboard.c (eval_dyn): New fun.
21110 (menu_item_eval_property): Use it.
21112 * image.c (parse_image_spec): Use Ffunctionp.
21114 * fns.c (concat, mapcar1): Accept byte-code-functions.
21116 * eval.c (Fsetq): Handle lexical vars.
21117 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21118 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21119 (FletX, Flet): Obey lexical binding.
21120 (Fcommandp): Handle closures.
21121 (Feval): New `lexical' arg.
21122 (eval_sub): New function extracted from Feval. Use it almost
21123 everywhere where Feval was used. Look up vars in lexical env.
21125 (Ffunctionp): Move from subr.el.
21126 (Ffuncall): Handle closures.
21127 (apply_lambda): Remove `eval_flags'.
21128 (funcall_lambda): Handle closures and new byte-code-functions.
21129 (Fspecial_variable_p): New function.
21130 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21131 but without exporting it to Lisp.
21133 * doc.c (Fdocumentation, store_function_docstring):
21134 * data.c (Finteractive_form): Handle closures.
21136 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21139 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21141 (exec_byte_code): New function extracted from Fbyte_code to handle new
21142 calling convention for byte-code-functions. Add new byte-codes.
21144 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21146 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21148 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21150 * xdisp.c (redisplay_internal): Fix prototype.
21152 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21154 * xdisp.c (SCROLL_LIMIT): New macro.
21155 (try_scrolling): Use it when setting scroll_limit.
21156 Limit scrolling to 100 screen lines.
21157 (redisplay_window): Even when falling back on "recentering",
21158 position point in the window according to scroll-conservatively,
21159 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21161 (try_scrolling): When point is above the window, allow searching
21162 as far as scroll_max, or one screenful, to compute vertical
21163 distance from PT to the scroll margin position. This prevents
21164 try_scrolling from unnecessarily failing when
21165 scroll-conservatively is set to a value slightly larger than the
21166 window height. Clean up the case of PT below the margin at bottom
21167 of window: scroll_max can no longer be INT_MAX. When aggressive
21168 scrolling is in use, don't let point enter the opposite scroll
21169 margin as result of the scroll.
21170 (syms_of_xdisp) <scroll-conservatively>: Document the
21171 threshold of 100 lines for never-recentering scrolling.
21173 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21175 * dispextern.h (move_it_by_lines):
21176 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21177 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21178 (message_log_check_duplicate): Remove parameters `prev_bol' and
21179 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21180 (redisplay_internal): Remove parameter `preserve_echo_area',
21181 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21183 * indent.c (Fvertical_motion):
21184 * window.c (window_scroll_pixel_based, Frecenter):
21185 Don't pass `need_y_p' to `move_it_by_lines'.
21187 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21189 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21190 steal a few bits to be more compact.
21191 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21192 Remove unneeded casts.
21194 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21196 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21198 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21199 binding" message (bug#7967).
21201 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21203 Fix more problems found by GCC 4.6.0's static checks.
21205 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21206 Remove unused local var.
21208 * editfns.c (Fmessage_box): Remove unused local var.
21210 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21211 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21212 Omit unused local vars.
21213 * window.c (shrink_windows): Omit unused local var.
21214 * menu.c (digest_single_submenu): Omit unused local var.
21215 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21216 Omit unused local var.
21218 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21219 Don't assume string length fits in int.
21220 (keyremap_step, read_key_sequence): Use size_t for sizes.
21221 (read_key_sequence): Don't check last_real_key_start redundantly.
21223 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21224 instead of alloca (Bug#8344).
21226 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21227 (Fbacktrace_frame): Don't assume nframes fits in int.
21229 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21231 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21234 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21236 * cm.c (calccost): Turn while-do into do-while, for clarity.
21238 * keyboard.c (syms_of_keyboard): Use the same style as later
21239 in this function when indexing through an array. This also
21240 works around GCC bug 48267.
21242 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21244 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21246 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21247 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21249 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21250 This avoids undefined behavior on integer overflow, and is a bit
21251 more convenient anyway since it is compared to a size_t variable.
21253 Variadic C functions now count arguments with size_t, not int.
21254 This avoids an unnecessary limitation on 64-bit machines, which
21255 caused (substring ...) to crash on large vectors (Bug#8344).
21256 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21257 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21258 All variadic functions and their callers changed accordingly.

21265 * fns.c (concat): Likewise.
21266 * frame.c (x_set_frame_parameters): Likewise.
21267 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21268 0 if not found, not -1. All callers changed.
21270 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21271 (stack_copy_size): Now size_t, not int.
21272 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21274 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21276 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21277 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21278 All callers changed.
21280 * lisp.h (multibyte_char_to_unibyte):
21281 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21282 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21284 * cmds.c (internal_self_insert):
21285 * editfns.c (general_insert_function):
21286 * keymap.c (push_key_description):
21287 * search.c (Freplace_match):
21288 * xdisp.c (message_dolog, set_message_1): All callers changed.
21290 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21292 * keyboard.c (safe_run_hook_funcall): New function.
21293 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21294 don't set the hook to nil, but remove the offending function instead.
21295 (Qcommand_hook_internal): Remove, unused.
21296 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21297 Vcommand_hook_internal.
21299 * eval.c (enum run_hooks_condition): Remove.

21478 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21480 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21481 unconditionally since it does the check itself.
21483 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21485 Fix more problems found by GCC 4.5.2's static checks.
21487 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21488 the first time through the loop, since we know p0 < p1 then.
21489 This also avoids a gcc -Wstrict-overflow warning.
21491 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21492 leading to a memory leak, possible in functions like
21493 load_charset_map_from_file that can allocate an unbounded number
21494 of objects (Bug#8318).
21496 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21497 that could (at least in theory) be that large.
21499 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21500 This is less likely to overflow, and avoids undefined behavior if
21501 overflow does occur. All callers changed. Use strtoul to scan
21502 for the unsigned long integer.
21503 (pint2hrstr): Simplify and tune code slightly.

21519 * process.c (Fmake_network_process): Use socklen_t, not int,
21520 where POSIX says socklen_t is required in portable programs.
21521 This fixes a porting bug on hosts like 64-bit HP-UX, where
21522 socklen_t is wider than int (Bug#8277).
21523 (Fmake_network_process, server_accept_connection):
21524 (wait_reading_process_output, read_process_output):

21537 Make tparam.h and terminfo.c consistent.
21538 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21539 Include tparam.h instead, since it declares them.
21540 * cm.h (PC): Remove extern decl; tparam.h now does this.
21541 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21542 * terminfo.c: Include tparam.h, to check interfaces.
21543 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21544 (tparam): Adjust signature to match interface in tparam.h;
21545 this removes some undefined behavior. Check that outstring and len
21546 are zero, which they always are with Emacs.
21547 * tparam.h (PC, BC, UP): New extern decls.
21549 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21550 (xftfont_open): Rename locals to avoid shadowing.

21590 (alsa_choose_format): Remove unused local var.
21591 (wav_play): Initialize a variable to 0, to prevent undefined
21592 behavior (Bug#8278).
21594 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21596 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21598 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21599 clobbering (Bug#8298).
21600 * sysdep.c (sys_subshell): Likewise.
21601 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21603 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21604 This should get cleaned up, so that child_setup has the
21605 same signature on all platforms.
21607 * callproc.c (call_process_cleanup): Now static.
21608 (relocate_fd): Rename locals to avoid shadowing.
21610 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21612 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21613 not to be necessary, and produces flickering.

21617 * config.in: Remove file.
21619 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21752 gcc -Wbad-function-cast warning.
21753 (default_value, arithcompare, arith_driver, arith_error): Now static.
21754 (store_symval_forwarding): Rename local to avoid shadowing.
21755 (Fmake_variable_buffer_local, Fmake_local_variable):
21756 Mark variables as initialized.

21761 Rename locals to avoid shadowing.
21762 (mark_stack): Move local variables into the #ifdef region where
21764 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
21765 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
21767 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
21768 (GC_STRING_CHARS): Remove; not used.
21769 (Fmemory_limit): Cast sbrk's returned value to char *.
21771 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21772 avoids undefined behavior in theory.
21774 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21776 Use functions, not macros, for up- and down-casing (Bug#8254).
21777 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21778 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21779 to use the following functions instead of these macros.
21780 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21781 EMACS_INT, since callers assume the returned value fits in int.
21782 (upcase1): Likewise, for UPCASE_TABLE.
21783 (uppercasep, lowercasep, upcase): New static inline functions.
21784 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
21785 the race-condition problem in the old DOWNCASE.
21787 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
21788 Rename locals to avoid shadowing.
21789 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
21790 (regex_compile, re_search_2, re_match_2_internal):
21791 Remove unused local vars.
21792 (FREE_VAR): Rewrite so as not to use empty "else",
21793 which gcc can warn about.
21794 (regex_compile, re_match_2_internal): Mark locals as initialized.
21795 (RETALLOC_IF): Define only if needed.
21796 (WORDCHAR_P): Likewise. This one is never needed, but is used
21797 only in a comment talking about a compiler bug, so put inside
21798 the #if 0 of that comment.
21799 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21800 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21803 * search.c (boyer_moore): Rename locals to avoid shadowing.
21804 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

21815 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
21817 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
21818 Rename locals to avoid shadowing.

21822 (casify_region): Mark local as initialized.
21824 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
21826 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21827 New macros, so that the caller can use some names other than
21828 gcpro1, gcpro2, etc.
21829 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21831 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21832 argument, for consistency with GCPRO2_VAR, etc: it is now the
21833 prefix of the variable, not the variable itself. All uses
21835 * dired.c (directory_files_internal, file_name_completion):
21836 Rename locals to avoid shadowing.
21838 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21839 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21840 dired.c's scmp function, had undefined behavior.
21841 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21842 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21843 * buffer.h: ... to here, because these macros use current_buffer,
21844 and the new implementation with inline functions needs to have
21845 current_buffer in scope now, rather than later when the macros
21847 (downcase, upcase1): New static inline functions.
21848 (DOWNCASE, UPCASE1): Reimplement using these functions.
21849 This avoids undefined behavior in expressions like
21850 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21851 from race conditions in accessing the global variables
21852 case_temp1 and case_temp2.
21853 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21854 * lisp.h (case_temp1, case_temp2): Remove their decls.
21855 * character.h (ASCII_CHAR_P): Move from here ...
21856 * lisp.h: ... to here, so that the inline functions mentioned
21857 above can use them.
21859 * dired.c (directory_files_internal_unwind): Now static.
21861 * fileio.c (file_name_as_directory, directory_file_name):
21862 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21864 (file_name_as_directory): Use const pointers when appropriate.
21865 (Fexpand_file_name): Likewise. In particular, newdir might
21866 point at constant storage, so make it a const pointer.
21867 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21868 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21870 (Fset_file_times, Finsert_file_contents, auto_save_error):

21875 to avoid shadowing.
21877 * marker.c (bytepos_to_charpos): Remove; unused.
21879 * lisp.h (verify_bytepos, count_markers): New decls,
21880 so that gcc does not warn that these functions aren't declared.
21882 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21883 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21884 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21885 (copy_text): Remove unused local var.
21887 * filelock.c (within_one_second): Now static.
21888 (lock_file_1): Rename local to avoid shadowing.
21890 * buffer.c (fix_overlays_before): Mark locals as initialized.
21891 (fix_start_end_in_overlays): Likewise. This function should be
21892 simplified by using pointers-to-pointers, but that's a different
21894 (switch_to_buffer_1): Now static.
21895 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21896 (report_overlay_modification): Rename locals to avoid shadowing.
21898 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21899 Fix pointer signedness issue.
21900 (sys_subshell): Mark local as volatile if checking for lint,
21901 to suppress a gcc -Wclobbered warning that does not seem to be right.
21902 (MAXPATHLEN): Define only if needed.
21904 * process.c (serial_open, serial_configure): Move decls from here ...
21905 * systty.h: ... to here, so that they can be checked.
21907 * fns.c (get_random, seed_random): Move extern decls from here ...
21908 * lisp.h: ... to here, so that they can be checked.
21910 * sysdep.c (reset_io): Now static.
21911 (wait_for_termination_signal): Remove; unused.
21913 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21918 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21919 (describe_map_tree):
21920 Rename locals to avoid shadowing.
21922 * keyboard.c: Declare functions static if they are not used elsewhere.

22070 1152921504606846976) returns the obviously-bogus value (-948597
22071 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22072 reports time overflow. See
