4 * ralloc.c (SIZE, POINTER, NIL):
5 * vm-limit.c (POINTER):
6 Remove, replacing all uses with C89 equivalents. These old
7 symbols were present only for porting to pre-C89 platforms.
9 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
11 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
12 This avoids warning messages reported as part of Bug#13546.
14 2013-02-21 Ken Brown <kbrown@cornell.edu>
16 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
18 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
20 * sheap.c (report_sheap_usage): Prefer message1_nolog.
22 * keyboard.c (Qcommand_execute): New var.
23 (command_loop_1, read_char): Use it.
24 (Fcommand_execute): Remove, replace by an Elisp implementation.
25 (syms_of_keyboard): Adjust accordingly.
27 2013-02-19 Daniel Colascione <dancol@dancol.org>
29 * sheap.c (report_sheap_usage): Use message, not message1, so
30 that we don't try to create a buffer while we're in the middle
31 of dumping Emacs. Explain why.
33 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
34 * search.c (find_newline): Return byte position in bytepos.

44 (get_visually_first_element, move_it_vertically_backward):
45 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
47 2013-02-19 Eli Zaretskii <eliz@gnu.org>
49 * w32proc.c (new_child): Avoid leaking handles if the subprocess
50 resources were not orderly released.
52 2013-02-17 Eli Zaretskii <eliz@gnu.org>
54 * xdisp.c (x_draw_vertical_border): For a window that is neither
55 the leftmost nor the rightmost, redraw both the left and the right
56 vertical borders. (Bug#13723)
58 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
60 * xml.c (init_libxml2_functions):

71 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
73 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
74 * frame.c (syms_of_frame): ... to here.
76 2013-02-16 Eli Zaretskii <eliz@gnu.org>
78 * w32.c (sys_chown): Remove unused function.
80 * w32term.c <input_signal_count>: Declare 'volatile'
81 unconditionally. (Bug#9066)
83 * w32.c (set_errno): Reset h_errno and don't set it to any other
84 value. Set errno instead.
85 (check_errno): Reset h_errno.
86 (sys_socket, socket_to_fd, sys_bind, sys_connect)
87 (sys_gethostname, sys_getservbyname, sys_getpeername)
88 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
89 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
91 (sys_gethostbyname): Set h_errno only errors detected.
93 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
95 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
97 2013-02-15 Eli Zaretskii <eliz@gnu.org>
99 * keyboard.c (read_char): Fix calculation of auto-save time out
100 when auto-save-timeout is less than 4. (Bug#13720)
102 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
103 time. Improve diagnostics in DebPrint. (Bug#13546)

108 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
109 make sure errno is set to an appropriate value. (Bug#13546)
110 (socket_to_fd): Add assertion against indexing fd_info[] with a
111 value that is out of bounds.
112 (sys_accept): If fd is negative, do not set up the child_process
113 structure for reading.
115 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
117 * composite.c (fill_gstring_header): Remove useless prototype.

129 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
131 Fix AIX port (Bug#13650).
132 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
133 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
134 was #undeffed earlier, so it cannot be used as a macro here.
135 Use the constant and not the macro.
137 2013-02-15 Eli Zaretskii <eliz@gnu.org>
139 * w32proc.c (new_child): If no vacant slots are found in
140 child_procs[], make another pass looking for slots whose process
141 has exited or died. (Bug#13546)

144 MAXDESC, set errno to EMFILE.
145 (_sys_read_ahead): Update cp->status when failing to read serial
146 communications input, so that the status doesn't stay at
147 STATUS_READ_IN_PROGRESS. (Bug#13546)
149 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
151 * gtkutil.c (tb_size_cb): New function.
152 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

156 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
159 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
161 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
163 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
165 * font.c (font_range): Add pos_byte argument. Adjust comment
167 * font.h (font_range): Adjust prototype.
168 * composite.c (autocmp_chars): Pass byte position to font_range.
169 Break long line. Remove useless prototype and format comment.
171 2013-02-13 Glenn Morris <rgm@gnu.org>
173 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
175 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
177 Improve AIX port some more (Bug#13650).
178 With this, it should be as good as it was in 23.3, though it's
179 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
180 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
181 * unexaix.c (start_of_text): Remove.
182 (_data, _text): Declare as char[], not int, as AIX manual suggests.
183 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
184 (orig_load_scnptr, orig_data_scnptr):
185 Now off_t, not long, since they are file offsets.
186 (make_hdr): Use _data, not start_of_data ().
187 This is the key part of the fix.
188 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
189 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
191 * pre-crt0.c (data_start): Initialize to 1.
192 This ports to compilers that optimize the external declaration
193 'int x = 0;' as if it were 'int x;' to shrink the executable.
195 Improve AIX port (Bug#13650).
196 This doesn't fix the bug, but it makes progress: Emacs builds now.
197 * unexaix.c: Include inttypes.h, stdarg.h.
198 (report_error, report_error_1): Mark as _Noreturn.
199 (report_error): Don't report the wrong errno.
200 (report_error_1): Now varargs. All callers changed.
201 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
202 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
203 (write_ptr): Use %p to print address rather than %lx and a cast
204 to unsigned long. Grow buffer a bit, to be safer.
206 2013-02-13 Eli Zaretskii <eliz@gnu.org>
208 * bidi.c (bidi_resolve_neutral): After finding the next
209 non-neutral character, accept NEUTRAL_ON type as well, because
210 directional control characters, such as LRE and RLE, have their
211 type converted to that by bidi_resolve_weak. This avoids aborts
212 when LRE/RLE follows a run of neutrals.
213 (bidi_move_to_visually_next): Assert that return value of
214 bidi_peek_at_next_level is non-negative. Negative values will
217 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
219 Minor getenv-related fixes.
220 * callproc.c (Fcall_process_region) [!DOS_NT]:
221 Avoid unnecessary duplicate call to getenv.
222 * callproc.c (init_callproc):
223 * dispnew.c (init_display):
224 * sysdep.c (sys_subshell):
225 Omit unnecessary cast of getenv or egetenv.
227 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
229 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
232 2013-02-12 Eli Zaretskii <eliz@gnu.org>
234 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
236 (display_line): Set w->region_showing to the value of
237 it->region_beg_charpos, not to -1. This fixes redisplay
238 optimization when cursor is moved up after M->. (Bug#13623)
240 (try_scrolling): Scroll text up more if point is too close to ZV
241 and inside the scroll margin. This makes sure point is moved
242 outside the scroll margin in these cases.
244 * window.h (struct window): region_showing can no longer be
247 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
249 Tune by using memchr and memrchr.
250 * doc.c (Fsnarf_documentation):
251 * fileio.c (Fsubstitute_in_file_name):
252 * search.c (find_newline, scan_newline):
253 * xdisp.c (pos_visible_p, display_count_lines):
254 Use memchr and memrchr rather than scanning byte-by-byte.
255 * search.c (find_newline): Rename from scan_buffer.
256 Omit first arg TARGET, as it's always '\n'. All callers changed.
258 Clean up read_key_sequence a tiny bit more.
259 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
260 (read_key_sequence): Remove unused locals.
262 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
264 Clean up read_key_sequence a bit; reread active keymaps after first event.
265 * keyboard.c (read_char, read_char_x_menu_prompt)
266 (read_char_minibuf_menu_prompt):
267 Replace nmaps+maps with a single `map' arg.
268 (follow_key): Operate on a single map.
269 (active_maps): New function.
270 (test_undefined): Also return true for nil bindings.
271 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
272 a single (composed) keymap. Remember `first_event' to choose the right
273 set of active keymaps. Recompute the set of keymaps after receiving
274 the first event. Remove GOBBLE_FIRST_EVENT.
275 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
276 * keyboard.h (read_char): Update declaration.
277 * lread.c (read_filtered_event): Adjust call to read_char.
279 2013-02-11 Eli Zaretskii <eliz@gnu.org>
281 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
282 Don't use the limitation on backwards movement when lines are truncated
283 in the window. (Bug#13675)
285 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
287 * marker.c (set_marker_internal): If desired position is passed
288 as a marker, avoid call to buf_charpos_to_bytepos.
289 * window.c (Fset_window_point): Omit redundant type checking.
290 (Fset_window_start): Likewise. Format comment.
291 (window_scroll_pixel_based): Use set_marker_restricted_both
292 with character and byte positions obtained from an iterator.
293 (Fset_window_configuration): Use set_marker_restricted_both.
294 * xdisp.c (message_dolog): Likewise.
296 2013-02-10 Eli Zaretskii <eliz@gnu.org>
298 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
299 When text lines are longer than window's screen lines, don't move back
300 too far. This speeds up some redisplay operations. (Bug#13675)
302 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
304 * syntax.c (scan_sexps_forward): Fix byte position calculation
305 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
307 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
309 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
312 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
314 Minor hashing refactoring.
315 * fns.c (SXHASH_REDUCE): Move to lisp.h.
316 (sxhash_float): Return EMACS_UINT, for consistency with the other
318 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
319 non-static inline function and therefore can't use static vars.
320 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
321 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
322 with the other hash functions.
324 2013-02-09 Eli Zaretskii <eliz@gnu.org>
326 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
327 XXXXXX part of the temporary file pattern is not downcased even
328 when w32-downcase-file-names is non-nil. (Bug#13661)
330 * xdisp.c (decode_mode_spec): Remove handling of %t.
332 * msdos.c (careadlinkatcwd): Remove.
334 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
336 * lread.c (skip_dyn_bytes): New function (bug#12598).

338 (load_each_byte): Remove. Update users.
340 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
342 * search.c (scan_buffer): Calculate end byte position just once.
343 (scan_newline): Do not recalculate start_byte.
344 (search_command): Use eassert.
345 * syntax.c (struct lisp_parse_state): New member location_byte.
346 (scan_sexps_forward): Record from_byte and avoid redundant
347 character to byte position calculation ...

365 * window.c (Fcurrent_window_configuration):
366 * xfaces.c (Fx_family_fonts):
367 * xselect.c (selection_data_to_lisp_data): Use it.
369 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
371 * coding.c (Fdefine_coding_system_internal): Use AREF where
372 argument is known to be a vector.
373 * fns.c (Flocale_info): Likewise for ASET.
374 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
375 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.

379 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
382 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
383 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
384 updateCollectionBehaviour.
386 * nsterm.m (NEW_STYLE_FS): Remove.
387 (ns_last_use_native_fullscreen): New variable.
388 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
389 (x_set_window_size): Do not take title bar and tool bar into account
390 if isFullscreen returns YES.
391 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
392 (check_native_fs): New function.
393 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
394 (ns_term_init): Remove NEW_STYLE_FS.
395 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
396 and tool bar if isFullscreen returns NO.
397 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
398 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
400 (window:willUseFullScreenPresentationOptions:): New method.
401 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
402 Hide toolbar if not enabled (Bug#13444).
403 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
404 Restore tool bar if enabled, hide it otherwise (Bug#13444).
405 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
406 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
407 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
408 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
409 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
410 (syms_of_nsterm): Add ns-use-native-fullscreen.
412 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
414 * fileio.c (Qchoose_write_coding_system): Now static.
416 2013-02-04 Eli Zaretskii <eliz@gnu.org>
418 * xdisp.c (window_buffer_changed): region_showing can be negative,
419 which still means region is being displayed.
420 (redisplay_internal): Resurrect code that forced redisplay of the
421 whole window when showing region and the mark has changed.
422 Record the new mark position to allow redisplay optimizations.
423 (display_line): If it->region_beg_charpos is non-zero, set the
424 window's region_showing member to -1. (Bug#13623) (Bug#13626)
426 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
427 not bitfield of 1 bit.
429 2013-02-03 Daniel Colascione <dancol@dancol.org>
431 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
432 daemon mode works on cygw32 when Emacs is installed and not just
435 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
437 Avoid file time stamp bug on MS-Windows (Bug#13149).
438 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
439 as FAT32 doesn't update time stamps when truncating them.
440 Also, check that a file time stamp is not a multiple of 100 ns;
441 this should catch all instances of the problem on MS-Windows,
442 as its native file system resolution is 100 ns or worse, and
443 checking for a non-multiple of 100 ns should impose only a small
444 overhead on systems with ns resolution.
446 2013-02-02 Eli Zaretskii <eliz@gnu.org>
448 Avoid encoding file names on MS-Windows when they need to be run
449 through dostounix_filename.
450 * w32.c (normalize_filename): Accept an additional argument
451 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
452 downcase it even if w32-downcase-file-names is non-nil.
453 (dostounix_filename): Accept an additional argument MULTIBYTE and
454 pass it to normalize_filename.
455 (emacs_root_dir): Adjust.
457 * msdos.h (dostounix_filename): Adjust prototype.
459 * w32.h (dostounix_filename): Adjust prototype.
461 * msdos.c (dostounix_filename): Accept an additional argument and
463 (init_environment): Adjust callers of dostounix_filename.
465 * fileio.c (Ffile_name_directory, file_name_as_directory)
466 (directory_file_name, Fexpand_file_name)
467 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
469 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
471 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
472 variables, as egetenv is case-insensitive for DOS_NT.
474 * dired.c (file_name_completion): Don't call Fdirectory_file_name
475 with an encoded file name.
477 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
478 Adjust calls to dostounix_filename.
480 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
482 * unexw32.c (unexec): Adjust call to dostounix_filename.
484 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
486 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
489 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
492 * callproc.c (Fcall_process): Make sure program name in PATH and
493 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
494 is passed to exec/spawnve, which fails unless the file-name
497 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
498 even if w32-quote-process-args is nil.
500 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
502 Fix timestamp bug when write-region appends nothing (Bug#13149).
503 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
504 the file's time stamp doesn't change if Emacs happens to write nothing
505 to the file, and on a buggy file system this could cause Emacs to
506 incorrectly infer that the file system doesn't have the bug.
507 Avoid this problem by inhibiting the inference in this case.
509 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
511 * window.h (struct window): Convert base_line_number, base_line_pos
512 and column_number_displayed members from Lisp_Object to ptrdiff_t.
513 Convert region_showing member from Lisp_Object to bitfield.
514 Remove sequence_number member. Adjust comments.
515 * window.c (sequence_number): Remove.
516 (make_window): Initialize column_number_displayed.
517 * print.c (print_object): Follow the printed representation of
518 frames and print window pointer to distinguish between windows.
519 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
520 * xdisp.c (wset_base_line_number, wset_base_line_pos)
521 (wset_column_number_displayed, wset_region_showing): Remove.
522 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
523 (try_scrolling, try_cursor_movement, redisplay_window)
524 (try_window_reusing_current_matrix, try_window_id, display_line)
525 (display_mode_lines, decode_mode_spec): Adjust users.
526 * .gdbinit (pwinx): Do not print sequence_number.
528 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
530 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
531 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
532 * dired.c: Include <fcntl.h>.
533 (open_directory): New function, which uses open and fdopendir
534 rather than opendir. DOS_NT platforms still use opendir, though.
535 (directory_files_internal, file_name_completion): Use it.
536 (file_attributes): New function, with most of the old Ffile_attributes.
537 (directory_files_internal, Ffile_attributes): Use it.
538 (file_attributes, file_name_completion_stat): First arg is now fd,
539 not dir name. All uses changed. Use fstatat rather than lstat +
541 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
542 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
543 (emacs_readlinkat): New function, with much of the old
544 Ffile_symlink_p, but with an fd argument for speed.
545 It uses readlinkat rather than careadlinkatcwd, so that it
546 need not assume the working directory.
547 (Ffile_symlink_p): Use it.
548 * filelock.c (current_lock_owner): Use emacs_readlinkat
549 rather than emacs_readlink.
550 * lisp.h (emacs_readlinkat): New decl.
551 (READLINK_BUFSIZE, emacs_readlink): Remove.
552 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
553 (emacs_norealloc_allocator, emacs_readlink): Remove.
554 This stuff is moved to fileio.c.
555 * w32.c (fstatat, readlinkat): New functions.
556 (careadlinkat): Don't check that fd == AT_FDCWD.
557 (careadlinkatcwd): Remove; no longer needed.
559 2013-01-31 Glenn Morris <rgm@gnu.org>
561 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
562 (Fwrite_region): Update for new choose_write_coding_system args.
563 Move the last piece of choose_write_coding_system here. (Bug#13522)
564 (syms_of_fileio): Add choose-write-coding-system.
566 2013-01-30 Eli Zaretskii <eliz@gnu.org>
568 * w32.c (sys_open): Zero out the flags for the new file descriptor.
569 (sys_close): Zero out the flags for the file descriptor before
570 closing it. (Bug#13546)
572 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
573 (logon_network_drive, stat_worker, symlink, chase_symlinks):
574 Use CharNextExA and CharPrevExA to iterate over file names encoded in
577 * w32.c (w32_get_long_filename, init_environment, readlink):
578 Support file names encoded in DBCS codepages.
579 (readlink): Use the current file-name-coding-system, not the ANSI
580 codepage, to decode and handle targets of symlinks.
582 2013-01-28 Eli Zaretskii <eliz@gnu.org>
584 * w32.c (opendir): Now accepts a 'const char *'.
586 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
588 Remove obsolete redisplay code. See the discussion at
589 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
590 * dispnew.c (preemption_period, preemption_next_check): Remove.
591 (Vredisplay_preemption_period): Likewise.
592 (update_frame, update_single_window, update_window, update_frame_1):
593 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
594 used, following the 2012-06-22 change.
596 2013-01-25 Eli Zaretskii <eliz@gnu.org>
598 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
600 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
602 * font.c (num_fonts): Remove the leftover from old
603 debugging code. Adjust comment style here and there.
604 * insdel.c (insert_1): Remove.
605 * lisp.h (insert_1): Remove prototype.
606 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
608 2013-01-25 Eli Zaretskii <eliz@gnu.org>
610 * w32.c (max_filename_mbslen): New function.
611 (normalize_filename, readdir): Use it to detect locales where ANSI
612 encoding of file names uses a double-byte character set (DBCS).
613 If a DBCS encoding is used, advance by characters using
614 CharNextExA, instead of incrementing a 'char *' pointer.
615 Use _mbslwr instead of _strlwr. (Bug#13515)
617 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
618 request of memory reservation to 1.7GB. (Bug#13065)
620 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
622 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
623 at check_extra_latin label. (Bug#13505)
625 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
627 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
628 Avoid redundant calls to strlen.
630 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
632 Drop async_visible and async_iconified fields of struct frame.
633 This is possible because async input is gone; for details, see
634 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
635 * frame.h (struct frame): Remove async_visible and async_iconified
636 members, convert garbaged to unsigned bitfield. Adjust comments.
637 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
638 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
639 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
640 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
641 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
643 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
644 properly. Likewise for obscured.
646 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
649 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
651 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
653 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
654 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
656 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
658 * xdisp.c (message2, message2_nolog): Remove functions.
659 (message3, message3_nolog): Extract nbytes and multibyteness directly
660 from the string. Change all callers.
661 (message3_nolog): Don't set message_enable_multibyte since set_message
662 will reset it anyway.
663 (message1, message1_nolog): Use message3.
664 (vmessage): Use a stack allocated buffer rather than f->message_buf.
665 (with_echo_area_buffer): Remove last two arguments. Update all callers.
666 (set_message): Drop all but the second arg, which has to be a string.
667 (set_message_1): Simplify now that we know that a1 is NULL and the
668 second arg is a string.
669 * frame.h (struct frame): Remove `message_buf' field.
670 Use glyphs_initialized_p instead.
671 (FRAME_MESSAGE_BUF): Remove macro.
672 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
673 * lisp.h (message2, message2_nolog): Remove declarations.
674 (message3, message3_nolog): Update declarations.
675 * keyboard.c (read_char_minibuf_menu_text)
676 (read_char_minibuf_menu_width): Remove vars.
677 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
678 to correctly handle multibyte strings.
679 * frame.c (delete_frame): Don't free message_buf any more.
680 * editfns.c (message_text, message_length): Remove vars.
681 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
682 * fileio.c (auto_save_error): Use message3 instead of message2.
683 * dispnew.c (adjust_frame_message_buffer): Remove function.
685 2013-01-23 Eli Zaretskii <eliz@gnu.org>
687 * w32term.c (w32fullscreen_hook): Account correctly for the screen
688 real estate used for the tool bar and the menu bar.
690 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
692 * insdel.c (prepare_to_modify_buffer): Force redisplay if
693 hidden buffer is prepared to modification (Bug#13164).
695 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
697 * window.h (struct window): Change window_end_valid member from
698 Lisp_Object to a bitfield. Adjust comments.
699 (wset_window_end_valid): Remove.
700 * window.c (adjust_window_count): Clear window_end_valid.
701 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
702 (Fwindow_line_height, set_window_buffer, Frecenter)
703 (Fsplit_window_internal, Fdelete_other_windows_internal)
704 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
705 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
706 * xdisp.c (check_window_end, reconsider_clip_changes)
707 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
708 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
709 (find_first_unchanged_at_end_row, try_window_id): Likewise.
711 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
713 * xdisp.c (mark_window_display_accurate): Simplify the loop
714 assuming that the only one of vchild, hchild or buffer window
715 slots is non-nil. Call mark_window_display_accurate_1 for
716 the leaf windows only.
717 (mark_window_display_accurate_1): Always assume leaf window.
720 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
722 * emacs.c (Qkill_emacs_hook): Now static.
724 * fileio.c (Finsert_file_contents): Simplify.
725 Remove unnecessary assignments and tests.
727 2013-01-21 Eli Zaretskii <eliz@gnu.org>
729 * w32.c (acl_set_file): Don't test for errors unless
730 set_file_security returns FALSE. Avoids spurious errors when
733 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
735 * fileio.c (Finsert_file_contents): Revert code introduced at
736 2013-01-18 in favor of the simpler and generally better fix.
737 Save stack space by removing 'buffer' and reusing 'read_buf'
740 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
742 * lisp.h (eabs): Define unconditionally (Bug#13419).
743 The old "#if !defined (eabs)" was an unnecessary revenant of back
744 when this macro was called "abs". Document 'eabs' better.
746 2013-01-19 Glenn Morris <rgm@gnu.org>
748 * fns.c (Frandom): Doc fix.
750 2013-01-19 Eli Zaretskii <eliz@gnu.org>
752 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
753 segfault when there are lots of overlays.
755 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
756 when there are lots of overlays.
757 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
758 for the details and a way to reproduce.
760 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
762 * fileio.c: Use O_APPEND to append.
763 This corresponds better to the natural interpretation of "append",
764 and avoids the need to open the output file twice, or to invoke
765 lseek when APPEND is neither nil nor a number.
766 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
767 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
768 file possibly twice, and lseeking to its end; this avoids the
769 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
770 at the same time: the combination is never needed and apparently
771 it doesn't work with DOS_NT.
773 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
774 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
776 Allow floating-point file offsets.
777 Problem reported by Vitalie Spinu in
778 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
779 * fileio.c (emacs_lseek): Remove.
780 (file_offset): New function.
781 (Finsert_file_contents, Fwrite_region): Use it.
783 2013-01-19 Chong Yidong <cyd@gnu.org>
785 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
786 aborting on Fsignal (Bug#13289).
788 2013-01-19 Eli Zaretskii <eliz@gnu.org>
790 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
791 set_file_security as failure due to insufficient privileges.
792 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
793 (fstat): Return owner and group like 'stat' and 'lstat' do.
795 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
797 Work around bug in CIFS and vboxsf file systems (Bug#13149).
798 The bug was observed on Ubuntu operating inside a virtual machine,
799 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
800 The workaround introduces a race condition on non-buggy hosts,
801 but it's an unlikely race and anyway there's a nearly identical
802 nearby race that can't be fixed.
803 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
805 (Fwrite_region): Test for file system time stamp bug.
806 (init_fileio): New function.
807 * lisp.h (init_fileio): Declare it.
808 * emacs.c (main): Call it.
810 * fileio.c (Finsert_file_contents): Simplify new diagnostic
811 and make it more consistent with other stat-failure diagnostics.
813 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
815 Fix crash when inserting data from non-regular files.
816 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
817 for the error description produced by valgrind.
818 * fileio.c (read_non_regular): Rename to read_contents.
819 Free Lisp_Save_Value object used to pass parameters.
820 (read_non_regular_quit): Rename to read_contents_quit.
821 (Finsert_file_contents): Redesign internal file reading loop to adjust
822 gap and end positions after each read and so help make_gap to work
823 properly. Do not signal an I/O error too early and so do not leave
824 not yet decoded characters in a buffer, which was the reason of
825 redisplay crash. Use list2 to build return value. Adjust comments.
827 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
829 Close a race when statting and reading files (Bug#13149).
830 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
831 This avoids a race if the file is renamed between stat and open.
832 This race is not the problem originally noted in Bug#13149;
833 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
835 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

842 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
843 * alloc.c (format_save_value): Rename to make_save_value.
844 (make_save_pointer): New function.
845 (record_xmalloc): Use make_save_pointer.
846 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
847 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
848 Change users of make_save_value to make_save_pointer.
849 Likewise for format_save_value and make_save_value.
851 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

858 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
860 * alloc.c (free_save_value): Now static.
862 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
864 * keymap.c (map_keymap_internal): Use format_save_value.
865 (map_keymap_char_table_item): Adjust accordingly.
866 * fileio.c (non_regular_fd, non_regular_inserted)
867 (non_regular_nbytes): Remove.
868 (Finsert_file_contents): Convert trytry to ptrdiff_t.
869 Use format_save_value to pass parameters to read_non_regular.
870 (read_non_regular): Use XSAVE_ macros to extract parameters.
872 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
874 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
876 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
878 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
879 extraction from any Lisp_Save_Value slot. Add type checking.
880 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
881 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
882 * xselect.c: All users changed.
884 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
886 Some convenient bits to deal with Lisp_Save_Values.
887 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.

897 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
899 Avoid needless casts with XSAVE_POINTER.
900 * alloc.c (mark_object) [GC_MARK_STACK]:
901 * dired.c (directory_files_internal_unwind):
902 * fileio.c (do_auto_save_unwind):
903 * gtkutil.c (pop_down_dialog):
904 * keymap.c (map_keymap_char_table_item):
905 * lread.c (load_unwind):
906 * nsmenu.m (pop_down_menu):
907 * print.c (print_object) [GC_MARK_STACK]:
908 * xfns.c (clean_up_file_dialog):
909 * xmenu.c (cleanup_widget_value_tree):
910 Omit casts between XSAVE_POINTER and a pointer type.
912 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
914 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
915 * eval.c (eval_sub): Protect `form' from being GCed before its
916 car and cdr becomes protected with the backtrace entry.
918 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
920 Make Lisp_Save_Value more versatile storage for up to four objects.
921 * lisp.h (toplevel): Enumeration to describe types of saved objects.
922 (struct Lisp_Save_Value): New layout. Adjust comments.
923 (XSAVE_POINTER): New macro.
924 (XSAVE_INTEGER): Likewise.
925 (allocate_misc): Add prototype.
926 (free_misc): Likewise.
927 * alloc.c (allocate_misc): Now global.
928 (free_misc): Likewise. Adjust comment.
929 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
930 (free_save_value): Likewise.
931 (mark_object): Likewise.
932 * editfns.c (save_excursion_save): Pack everything within
933 Lisp_Save_Value and so avoid xmalloc.
934 (save_excursion_restore): Adjust to match new layout. Use free_misc
935 because we do not allocate extra memory any more. Add eassert.
936 * print.c (print_object): New code to print Lisp_Save_Value. Do not
937 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
938 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
939 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
940 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
942 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

951 Fix SIGDANGER handlers, for AIX (Bug#13408).
952 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
953 Move handlers here from emacs.c; they were out of place.
955 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
957 * xterm.c (syms_of_xterm): Adjust documentation for
958 scroll-bar-adjust-thumb-portion.

962 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
963 determine whether scroll bar thumb size should be adjusted or
964 not. Use variable for MOTIF.
966 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
969 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>
971 * nsterm.m (keyDown:): Set processingCompose to NO if an emacs key
973 (doCommandBySelector:): Set processingCompose to NO.
975 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
976 Remove check for fkeys count > zero, block/unblock fixes the real bug.
977 (nsfont_list_family): Add block/unblock_input calls.
978 (nsfont_open): Move block_input earlier. Add unblock_input before early
980 (nsfont_draw): Add block/unblock_input calls.
982 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
984 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
985 for old_charpos and old_bytepos.
987 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>

1003 string cross-reference(s).
1005 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1007 Avoid unnecessary byte position calculation for the gap movement.
1008 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1009 anyway, all of them should use move_gap_both instead.
1010 * lisp.h (move_gap): Remove prototype.
1011 * insdel.c (move_gap): Remove.
1012 (move_gap_both): Add eassert.

1018 emacsclient -t should not suspend Emacs server (Bug#13387)
1019 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1021 * term.c (init_tty): Use them instead of rolling our own code.
1022 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1023 switches from 'signal' to 'pthread_sigmask', which is safer in
1024 multithreaded applications.
1025 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1026 which has already arranged for that.
1027 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1028 This is the main part of the bug fix.
1030 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
1032 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around

1035 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
1037 Omit buffer_slot_type_mismatch and use generic predicates to enforce
1038 the type of per-buffer values where appropriate.
1039 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
1040 predicate, which is how it's really used now. Adjust comment.
1041 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1042 * buffer.c (buffer_slot_type_mismatch): Remove.
1043 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1044 predicate. Adjust comment.
1045 (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for
1046 fill-column, left-margin, tab-width, buffer-saved-size,
1047 left-margin-width, right-margin-width, left-fringe-width,
1048 right-fringe-width, scroll-bar-width and buffer-display-count.
1049 Use Qstringp for default-directory, buffer-file-name,
1050 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1051 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1053 * data.c (store_symval_forwarding): Adjust to call the predicate.
1055 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
1057 * w32.c (get_name_and_id, acl_set_file):

1067 (syms_of_editfns): Adjust defsubr. Drop commented-out obsolete code.
1068 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
1069 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1070 (make_gap_1): New function to adjust the gap of any buffer.
1071 * coding.c (coding_alloc_by_making_gap): Use it.
1072 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1073 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1075 2013-01-08 Juri Linkov <juri@jurta.org>
1077 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
1078 of (supports :underline (:style wave)). (Bug#13000)

1082 * undo.c (Fprimitive_undo): Move to simple.el.
1083 (syms_of_undo): Remove declarations for Sprimitive_undo.
1085 2013-01-08 Stefan Monnier <monnier@iro.umontreal.ca>
1087 * keyboard.c (echo_add_key): Rename from echo_add_char.
1089 2013-01-06 Chong Yidong <cyd@gnu.org>
1091 * keyboard.c (echo_add_char): New function, factored out from
1092 echo_char. Don't add a space if the previous echo string was

1096 trailing dash is properly added.
1098 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1100 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1101 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1102 digits for buffer positions, before misalignment starts.
1103 Display "0" for integer "object" field.
1104 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1105 Display the newline glyph more unambiguously.
1107 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1109 * nsterm.m (ns_draw_underwave):
1110 * w32term.c (w32_draw_underwave):
1111 * xterm.c (x_draw_underwave): Make underwave look more triangular
1112 and also degrade gracefully for small fonts. (Bug#13000)
1114 * nsterm.m (ns_draw_text_decoration):
1115 * w32term.c (x_draw_glyph_string):
1116 * xterm.c (x_draw_glyph_string): Don't use previous underline
1117 thickness and position if previous underline type is underwave.
1119 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1121 * fileio.c (Ffile_acl): Undocument return format.
1123 2013-01-02 Glenn Morris <rgm@gnu.org>
1125 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
1127 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
1130 * dired.c (file_name_completion):
1131 * doc.c (get_doc_string):

1133 * font.c (font_score, font_delete_unmatched):
1134 * fringe.c (compute_fringe_widths):
1135 * lread.c (read_list):
1136 * minibuf.c (Ftry_completion):
1137 * term.c (tty_ins_del_lines):
1138 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1139 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1141 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1143 * w32.c (unsetenv): Set up the string passed to _putenv
1145 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1146 for the bug this caused.
1148 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1150 * coding.c (Qmac): Now static.
1152 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1154 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1155 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1157 toolbar_is_packed to true.
1158 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
1159 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1160 Show all on TOOLBAR_TOP_WIDGET.
1161 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1162 by TOOLBAR_TOP_WIDGET.
1163 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1164 Check toolbar_is_packed.
1165 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1166 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1167 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1169 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1170 (xg_update_menubar): Update title only if
1171 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1172 (xg_update_submenu): Skip tearoff only if
1173 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1174 (xg_initialize): Initialize xg_detached_menus only if
1175 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1177 * xterm.h (struct x_output): Surround handlebox_widget with
1178 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1179 toolbar_in_hbox is bool.
1181 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1183 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1184 (LIBS_GNUSTEP): Define.
1185 (LIBES): Add $(LIBS_GNUSTEP).
1186 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1188 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1190 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1191 continuation glyph on a TTY with an indication of an empty line.
1194 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1196 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1197 file's SELinux context or ACLs successfully set, nil otherwise.
1199 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1201 * w32proc.c (reader_thread): Avoid passing NULL handles to
1202 SetEvent and WaitForSingleObject.
1204 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1206 Port EXTERNALLY_VISIBLE to Clang 3.2.
1207 * conf_post.h (__has_attribute): New macro.
1208 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1210 2012-12-27 Glenn Morris <rgm@gnu.org>
1212 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1213 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1215 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1217 * fileio.c (file_name_as_directory, directory_file_name):
1218 Accept an additional argument MULTIBYTE to indicate whether the input C
1219 came from a multibyte or a unibyte Lisp string; all callers
1220 adjusted. Don't assume the input string is always multibyte.
1222 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1223 don't ENCODE_FILE them, and return a unibyte string if the input
1225 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1226 don't assume the input strings will always be multibyte. If the
1227 input strings are multibyte, decode strings obtained from C
1230 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1232 * lisp.h (toplevel): Add two notices to the comment about
1233 defining a new Lisp data type.

1237 * alloc.c (valid_lisp_object_p): Adjust comment.
1239 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1241 * keyboard.c (record_asynch_buffer_change): Initialize an event
1242 only if it's really needed.
1243 * frame.h (enum output_method): Remove output_mac member since
1244 it's a leftover from the deleted code.
1245 * frame.c (Fframep): Adjust user here ...
1246 * terminal.c (Fterminal_live_p): ... and here.
1247 * coding.c (Qmac): Now here because it's only used to denote
1248 end-of-line encoding type.
1249 (syms_of_coding): DEFSYM it.
1250 * frame.h (Qmac): Remove duplicated declaration.
1252 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1254 * window.c (select_window_1): Now static, since it's used only here.
1256 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1258 * window.c (window_body_cols): Subtract display margins from the
1259 window body width on TTYs as well. See
1260 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1261 for the original report.
1263 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1265 * xdisp.c (redisplay_window): Remove inner local variable
1266 because the outer shadowed one has the same meaning.
1267 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1269 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1270 (xg_create_tool_bar): Adjust users.
1272 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1274 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1275 * buffer.c (Fget_buffer_create): Use it to set compact field of
1276 struct buffer_text to avoid accessing an uninitialized value
1277 when compact_buffer is called for the first time.
1278 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1279 (Fset_buffer_modified_p): Use buffer_window_count to check
1280 whether the buffer is displayed in some window.
1281 * xdisp.c (message_dolog): Likewise.
1283 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1285 * w32.c (acl_set_file): If setting the file security descriptor
1286 fails, and the new DACL is identical to the existing one, silently
1287 return success. This fixes problems for users backing up their
1288 own files without having the necessary privileges for setting
1289 security descriptors.
1291 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1293 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1294 after WaitForSingleObject returns normally. This expedites reader
1295 thread shutdown when delete_child triggers it.
1296 (reap_subprocess): More accurate commentary for why we call
1297 delete_child only when cp->fd is negative.
1299 * w32.c (sys_close): Do not call delete_child on a subprocess
1300 whose handle is not yet closed. Instead, set its file descriptor
1301 to a negative value, so that reap_subprocess will call
1302 delete_child on that subprocess when its SIGCHLD arrives.
1303 This avoids closing handles used for communications between sys_select
1304 and reader_thread, which doesn't give sys_select a chance to
1305 notice that the process exited and invoke the SIGCHLD handler for
1308 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1310 * nsfns.m (Fns_do_applescript): Run event loop until script has
1311 been executed (Bug#12969).

1317 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1319 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1321 * w32term.c (w32fullscreen_hook): New function.
1322 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1324 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1326 * fileio.c (Finsert_file_contents): Doc fix.
1328 * w32proc.c (new_child, delete_child, find_child_pid): For a
1329 subprocess, consider its slot being in use as long as its process
1330 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1331 slot when a new process is started immediately after killing
1332 another one, without waiting enough time for the first process to
1333 be reaped and resources allocated for it be orderly freed.
1335 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1337 2012-12-21 Chong Yidong <cyd@gnu.org>
1339 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1341 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1343 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1345 * w32.c (get_name_and_id): Always pass NULL as the first argument
1346 of lookup_account_sid. Avoids crashes with UNC file names that
1347 refer to DFS domains, not to specific machine names. (Bug#12621)
1348 Remove now unused argument FNAME; all callers changed.
1349 (get_file_owner_and_group): Remove now unused argument FNAME; all
1352 2012-12-21 Chong Yidong <cyd@gnu.org>
1354 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1355 error for invalid chars, don't check for a nil return value.
1357 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1359 Avoid calls to CHAR_TO_BYTE if byte position is known.
1360 * editfns.c (make_buffer_string_both): Use move_gap_both.
1361 (Fbuffer_string): Use make_buffer_string_both.
1362 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1364 (buf_bytepos_to_charpos): Likewise.
1365 (charpos_to_bytepos): Remove.
1366 * fileio.c (Finsert_file_contents): Use move_gap_both.
1367 * search.c (Freplace_match): Likewise.
1368 * process.c (process_send_region): Likewise. Use convenient
1369 names for byte positions.
1370 * lisp.h (charpos_to_bytepos): Remove prototype.
1371 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1372 * insdel.c (move_gap): Likewise.

1378 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1380 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1381 (redisplay_internal): Don't bother selecting the frame to get the
1382 proper value of frame-local variables (bug#13225).
1384 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1386 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1387 Rename 4th argument since it may be buffer or string. Adjust comment.
1388 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1390 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1392 * coding.c (Fdetect_coding_region): Do not check start and end with
1393 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1394 (code_convert_region): Likewise.
1396 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1398 * w32.c (acl_get_file, acl_set_file): Run the file name through
1399 map_w32_filename, and resolve any symlinks in the file name, like
1401 (acl_set_file): Call revert_to_self, if any privileges were
1404 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1406 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1407 ($(BLD)/w32.$(O)): Update dependencies.
1409 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1411 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1412 propagate redisplay's scrolling (if any) to the right window.
1413 (redisplay_internal): Use ensure_selected_frame.
1414 (display_mode_lines): Complete last fix.
1415 * window.c (select_window_1): New func, extracted from select_window.
1416 (select_window): Use it.
1417 * window.h (select_window_1): Declare.
1419 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1421 Emulate Posix ACL APIs on MS-Windows.
1422 * w32.c: Include sddl.h and sys/acl.h.
1423 (SDDL_REVISION_1): Define if not already defined.
1424 (g_b_init_get_security_descriptor_dacl)

1443 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1445 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1446 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1447 for some of that bug's symptoms can now cause Emacs to abort.
1448 Remove the workaround.
1449 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1450 The bug that caused SIGCHLD to get lost has been fixed, and the
1451 workaround for it can now cause Emacs to abort.
1453 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1455 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1463 and copy ACL entries of file in addition to SELinux context if set.
1464 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1466 * Makefile.in (LIBACL_LIBS): New macro.

1481 * w32proc.c (new_child): Initialize input_file and
1482 pending_deletion members of the child.

1486 (record_infile, record_pending_deletion): New functions.
1487 (reap_subprocess): Fix a typo in DebPrint string.
1488 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1490 * fileio.c (internal_delete_file): Return an int again: non-zero

1495 * callproc.c (Fcall_process): Don't overwrite infile with result
1497 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1498 asynchronous subprocess, record the name of the input file name,
1500 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1501 delete the file, record it as pending deletion when the subprocess
1504 2012-12-14 Eli Zaretskii <eliz@gnu.org>

1526 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1527 try to get accurate owner and group information from NT file
1528 security APIs. This is to make most callers of 'stat' and
1529 'lstat', which don't need that information, much faster.
1531 * dired.c (Ffile_attributes) [WINDOWSNT]:
1532 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1533 owner and group information from 'lstat'.
1535 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1537 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1538 as that confuses set-auto-coding, so insist on the head-read
1539 returning the full 1024 bytes. Let lseek compute the tail offset;
1540 less work for us. Do not ignore I/O errors when reading the tail.

1564 files, fixing a regression from 24.2.
1565 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1567 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1569 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1570 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1571 Remove unnecessary S_ISLNK test, as (contra the comments) this
1572 function can't copy symlinks. Improve quality of error message
1573 when attempting to copy files that are neither regular files nor

1592 * inotify.c (inotify_callback): Generate an Emacs event for every
1593 incoming inotify event.
1595 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1597 * xdisp.c (handle_face_prop): Fix logic of computing
1598 it->start_of_box_run_p.

1656 (hinst): Remove unneeded extern declaration.
1657 (_start): Remove initialization of above variables; remove

1877 * frame.c (make_frame): Do not set window's buffer to t.
1878 * window.c (Fsplit_window_internal): Likewise. Previously it was

1910 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1912 Fix a recently-introduced delete-process race condition.
1913 * callproc.c, process.h (record_kill_process):
1914 New function, containing part of the old call_process_kill.
1915 (call_process_kill): Use it.
1916 This does not change call_process_kill's behavior.
1917 * process.c (Fdelete_process): Use record_kill_process to fix a
1918 race condition that could cause Emacs to lose track of a child.
1920 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1922 Avoid code duplication between prev_frame and next_frame.
1923 * frame.c (candidate_frame): New function. Add comment.
1924 (prev_frame, next_frame): Use it. Adjust comment.
1926 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1928 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1929 fails, signal an error instead of continuing with an empty
1931 Encode expanded temp file pattern before passing it to mkstemp or
1934 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1935 Encode the file name before passing it to dostounix_filename, in
1936 case it will downcase it (under w32-downcase-file-names).
1939 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1941 Minor call-process cleanups.
1942 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1943 at the same time as other platforms, to simplify analysis.
1944 No need for fd0_volatile since we have synch_process_fd.
1945 Avoid needless emacs_close; arg is always negative.
1947 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1949 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1952 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1954 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1955 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1956 and mouse_face_hidden members to a bitfields.
1957 * frame.h (struct frame): Remove set-but-not-used space_width member.
1958 (FRAME_SPACE_WIDTH): Remove.
1959 * nsterm.m, w32term.c, xterm.c: Adjust users.
1960 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1961 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1962 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1963 members to a bitfields.
1965 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1967 Don't let call-process be a zombie factory (Bug#12980).
1968 Fixing this bug required some cleanup of the signal-handling code.
1969 As a side effect, this change also fixes a longstanding rare race
1970 condition whereby Emacs could mistakenly kill unrelated processes,
1971 and it fixes a bug where a second C-g does not kill a recalcitrant
1972 synchronous process in GNU/Linux and similar platforms.
1973 The patch should also fix the last vestiges of Bug#9488,
1974 a bug which has mostly been fixed on the trunk by other changes.
1975 * callproc.c, process.h (synch_process_alive, synch_process_death)
1976 (synch_process_termsig, sync_process_retcode):
1977 Remove. All uses removed, to simplify analysis and so that
1978 less consing is done inside critical sections.
1979 * callproc.c (call_process_exited): Remove. All uses replaced
1980 with !synch_process_pid.
1981 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1982 These take the role of what used to be in unwind-protect arg.
1984 (block_child_signal, unblock_child_signal):
1985 New functions, to avoid races that could kill innocent-victim processes.
1986 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1987 (call_process_kill): Record killed processes as deleted, so that
1988 zombies do not clutter up the system. Do this inside a critical
1989 section, to avoid a race that would allow the clutter.
1990 (call_process_cleanup): Fix code so that the second C-g works again
1991 on common platforms such as GNU/Linux.
1992 (Fcall_process): Create the child process in a critical section,
1993 to fix a race condition. If creating an asynchronous process,
1994 record it as deleted so that zombies do not clutter up the system.
1995 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1996 light of these changes. Omit unnecessary call to emacs_close
1997 before failure, as the unwind-protect code does that.
1998 * callproc.c (call_process_cleanup):
1999 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2000 * process.c (record_deleted_pid): New function, containing
2001 code refactored out of Fdelete_process.
2002 (Fdelete_process): Use it.
2003 (process_status_retrieved): Remove. All callers changed to use
2004 child_status_change.
2005 (record_child_status_change): Remove, folding its contents into ...
2006 (handle_child_signal): ... this signal handler. Now, this
2007 function is purely a handler for SIGCHLD, and is not called after
2008 a synchronous waitpid returns; the synchronous code is moved to
2009 wait_for_termination. There is no need to worry about reaping
2010 more than one child now.
2011 * sysdep.c (get_child_status, child_status_changed): New functions.
2012 (wait_for_termination): Now takes int * status and bool
2013 interruptible arguments, too. Do not record child status change;
2014 that's now the caller's responsibility. All callers changed.
2015 Reimplement in terms of get_child_status.
2016 (wait_for_termination_1, interruptible_wait_for_termination):
2017 Remove. All callers changed to use wait_for_termination.
2018 * syswait.h: Include <stdbool.h>, for bool.
2019 (record_child_status_change, interruptible_wait_for_termination):
2021 (record_deleted_pid, child_status_changed): New decls.
2022 (wait_for_termination): Adjust to API changes noted above.
2024 * bytecode.c, lisp.h (Qbytecode): Remove.
2025 No longer needed after 2012-11-20 interactive-p changes.
2027 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2029 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2030 the scroll margin, move point outside the margin. (Bug#13055)
2032 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2034 * gtkutil.c (my_log_handler): New function.
2035 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2037 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2039 * lisp.h (modify_region): Rename to...
2040 (modify_region_1): ...new prototype.
2041 * textprop.c (modify_region): Now static. Adjust users.
2042 * insdel.c (modify_region): Rename to...
2043 (modify_region_1): ...new function to work with current buffer.
2044 Adjust comment and users. Use true and false for booleans.
2046 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2048 * alloc.c (free_save_value): New function.
2049 (safe_alloca_unwind): Use it.
2050 * lisp.h (free_save_value): New prototype.
2051 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2053 (save_excursion_restore): Adjust to match saved data structure.
2054 Use free_save_value to offload some work from GC. Drop obsolete
2057 2012-12-03 Chong Yidong <cyd@gnu.org>
2059 * fileio.c (Vauto_save_list_file_name): Doc fix.
2061 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2063 * w32fns.c: Remove prototype of atof.
2064 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2066 (file_dialog_callback): Make it UINT_PTR.
2068 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2071 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2072 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2075 2012-12-03 Glenn Morris <rgm@gnu.org>
2077 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2079 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2081 Fix xpalloc confusion after memory is exhausted.
2082 * alloc.c (xpalloc): Comment fix.
2083 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2084 and signals an error, do not clear charset_table_size, as
2085 charset_table is still valid.
2086 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2088 Use execve to avoid need to munge environ (Bug#13054).
2089 * callproc.c (Fcall_process):
2090 * process.c (create_process):
2091 Don't save and restore environ; no longer needed.
2092 * callproc.c (child_setup):
2093 Use execve, not execvp, to preserve environ.
2095 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2097 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2099 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2101 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2102 display for sliced images (Bug#10500).
2104 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2106 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2108 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2109 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2111 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2113 * xdisp.c (window_outdated): Remove eassert since it hits
2114 some suspicious corner cases (see Bug#13007 and Bug#13012).
2115 (mode_line_update_needed): New function.
2116 (redisplay_internal, redisplay_window): Use it.
2117 (ensure_selected_frame): New function.
2118 (redisplay_internal, unwind_redisplay): Use it.
2119 (redisplay_internal): Move comment about buffer_shared...
2120 (buffer_shared_and_changed): ...near to its real use.
2122 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2124 * callproc.c (Fcall_process): Don't misreport vfork failure.
2126 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2128 * callproc.c (Fcall_process): Fix vfork portability problems.
2129 Do not assume that fd[0], count, filefd, and save_environ survive
2130 vfork. Fix bug whereby wrong errno value could be reported for
2131 pipe failure. Some minor cleanups, too, as follows. Move buf and
2132 bufsize to the context where they're needed. Change new_argv to
2133 be of type char **, as this is more convenient and avoids casts.
2134 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2135 Now local constants, not macros.
2137 2012-11-18 Kenichi Handa <handa@gnu.org>
2139 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2140 for the variable "f".
2142 2012-11-13 Kenichi Handa <handa@gnu.org>
2144 * font.c (font_unparse_xlfd): Exclude special characters from the
2145 generating XLFD name.
2147 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2187 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2188 between bpos_covered and bpos_max. This fixes cursor display when
2189 several display strings follow each other.
2191 * .gdbinit (pgx): If the glyph's object is a string, display the
2192 pointer to string data, rather than the value of the string object
2193 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2195 * indent.c (Fvertical_motion): If the starting position is covered
2196 by a display string, return to one position before that, to avoid
2197 overshooting it inside move_it_to. (Bug#12930)
2199 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2210 Drop unused pending_menu_activation member.
2211 * xterm.h (struct x_output): Drop outdated #if 0 code.
2212 Use bitfields for explicit_parent, asked_for_visible,
2213 has_been_visible and net_wm_state_hidden_seen members.

2218 of a literal "/". (Bug#12955)
2219 (gl-stamp): Invoke fc.exe directly, not through cmd.

2224 * dired.c: Assume HAVE_DIRENT_H.
2225 (NAMLEN): Remove, replacing with ...
2226 (dirent_namelen): New function. All uses changed. Use the GNU macro
2227 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2228 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2229 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2230 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2232 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2233 * ndir.h: Rename to ../nt/inc/dirent.h.
2234 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2235 Do not include <dirent.h>; no longer needed.
2236 * w32.c: Include <dirent.h> rather than "ndir.h".
2238 2012-11-23 Chong Yidong <cyd@gnu.org>
2240 * xftfont.c (xftfont_open): Remove duplicate assignment.
2242 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2244 * alloc.c (Fgarbage_collect): Unblock input after clearing
2245 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2246 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2247 * msdos.c (IT_frame_up_to_date): Use it here...
2248 * w32term.c (w32_frame_up_to_date): ...here...
2249 * xterm.c (XTframe_up_to_date): ...and here...
2250 * nsterm.m (ns_frame_up_to_date): ...but not here.

2262 'tail' and 'frame' local variables.
2264 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2266 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2267 with Windows system header.

2289 Cygwin builds, not just GTK builds. See
2290 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2292 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2294 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2295 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2296 Define for the MSVC compiler.
2298 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2300 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2301 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2302 dostounix_filename. Prevents crashes down the road, because
2303 dostounix_filename assumes it gets a unibyte string.
2304 Reported by Michel de Ruiter <michel@sentient.nl>, see
2305 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

2343 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2344 cygwin_convert_file_name*.
2346 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2347 Rename cygwin_convert_path* to cygwin_convert_file_name*.

2353 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2355 * w32select.c: Include w32common.h before w32term.h, so that
2356 windows.h gets included before w32term.h uses some of its
2357 features, see below.
2359 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2361 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2363 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2365 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2367 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2368 (ns_select): Return at once if events are held (Bug#12834).
2370 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2372 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2373 Needed following 2012-10-20 change. (Bug#12902)
2375 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2377 * w32proc.c (waitpid): Remove unused label get_result.
2379 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2381 * makefile.w32-in (SYSWAIT_H): New macro.
2382 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2383 ($(BLD)/sysdep.$(O)): Update dependencies.
2385 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2387 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2388 * callproc.c (relocate_fd): Assume F_DUPFD.
2389 * emacs.c, term.c (O_RDWR): Remove.
2390 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2391 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2392 * nsterm.m: Assume <fcntl.h> exists.
2393 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2394 (create_pty, Fmake_network_process, server_accept_connection)
2395 (wait_reading_process_output, init_process_emacs):
2397 (wait_reading_process_output): Put in a special case for WINDOWSNT
2398 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2399 It's not clear this is needed, but it's a more-conservative change.
2400 (create_process): Assume FD_CLOEXEC.
2401 (create_process, create_pty): Assume O_NOCTTY.
2402 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2403 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2404 Omit if not DOS_NT, since F_GETFL is not defined there.
2405 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2406 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2408 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2409 lack it, since gnulib guarantees this.
2410 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2412 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2414 * w32.c (faccessat): Pretend that directories have the execute bit
2415 set. Emacs expects that, e.g., in files.el:cd-absolute.
2417 * w32proc.c (create_child): Don't clip the PID of the child
2418 process to fit into an Emacs integer, as this is no longer a
2420 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2421 reaping only the process specified by PID argument, if that is
2422 positive. Use PID instead of dead_child to know which process to
2423 reap. Wait for the child to die only if WNOHANG is not in
2425 (sys_select): Don't set dead_child.
2427 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2428 as it is no longer needed.
2430 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2432 (record_child_status_change): Remove the setting of
2433 record_at_most_one_child for the !WNOHANG case.
2435 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2437 Fix problems in ns port found by static checking.
2438 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2439 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2440 not to process group.
2441 (ns_select): Use emacs_write, not write, as that's more robust
2442 in the presence of signals.
2443 (fd_handler:): Check for read errors.
2445 2012-11-16 Glenn Morris <rgm@gnu.org>
2447 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2449 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2451 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2453 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2455 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2456 use the same value of thread handle.
2457 (start_timer_thread): If the timer thread exited (due to error),
2458 clean up by closing the two handles it used. Duplicate the caller
2459 thread's handle here, so it gets duplicated only once, when
2460 launching the timer thread. Set priority of the timer thread, not
2462 (getitimer): Don't duplicate the caller thread's handle here.
2465 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2467 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2470 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2472 Remove no-longer-used pty_max_bytes variable.
2473 * process.c (pty_max_bytes): Remove; unused.
2474 (send_process): Do not set it.
2476 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2478 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2479 Update dependencies.
2481 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2483 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2484 This follows up on the 2012-09-29 patch that removed indirection
2485 for the 'function' field. Reported by Sergey Vinokurov in
2486 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2488 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2490 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2491 different name, as the MS runtime does not have such a function,
2492 and probably never will.) All callers changed. Ignore DIRFD
2493 value if PATH is an absolute file name, to match Posix spec
2494 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2497 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2499 * xdisp.c (echo_area_display, redisplay_internal):
2500 Omit redundant check whether frame_garbaged is set.
2502 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2504 Use faccessat, not access, when checking file permissions (Bug#12632).
2505 This fixes a bug that has been present in Emacs since its creation.
2506 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2507 which must set some sort of record. (Torek's bug report was against
2508 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2509 same common flaw.) See Torek's Usenet posting
2510 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2511 Posted: Fri Apr 8 14:18:56 1983.
2512 * Makefile.in (LIB_EACCESS): New macro.
2514 * callproc.c (init_callproc):
2515 * charset.c (init_charset):
2516 * fileio.c (check_existing, check_executable, check_writable)
2518 * lread.c (openp, load_path_check):
2519 * process.c (allocate_pty):
2521 Use effective UID when checking permissions, not real UID.
2522 * callproc.c (init_callproc):
2523 * charset.c (init_charset):
2524 * lread.c (load_path_check, init_lread):
2525 Test whether directories are accessible, not merely whether they exist.
2526 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2527 * fileio.c (check_existing, check_executable, check_writable)
2529 Use symbolic names instead of integers for the flags, as they're
2531 (check_writable): New arg AMODE. All uses changed.
2532 Set errno on failure.
2533 (Ffile_readable_p): Use faccessat, not stat + open + close.
2534 (Ffile_writable_p): No need to call check_existing + check_writable.
2535 Just call check_writable and then look at errno. This saves a syscall.
2536 dir should never be nil; replace an unnecessary runtime check
2537 with an eassert. When checking the parent directory of a nonexistent
2538 file, check that the directory is searchable as well as writable, as
2539 we can't create files in unsearchable directories.
2540 (file_directory_p): New function, which uses 'stat' on most platforms
2541 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2542 (Ffile_directory_p, Fset_file_times): Use it.
2543 (file_accessible_directory_p): New function, which uses a single
2544 syscall for efficiency.
2545 (Ffile_accessible_directory_p): Use it.
2546 * xrdb.c (file_p): Use file_directory_p.
2547 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2548 * lread.c (openp): When opening a file, use fstat rather than
2549 stat, as that avoids a permissions race. When not opening a file,
2550 use file_directory_p rather than stat.
2551 (dir_warning): First arg is now a usage string, not a format.
2552 Use errno. All uses changed.
2553 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2554 that merely introduced a race.
2555 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2556 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2557 and similarly for the other O_* flags.
2558 * w32.c (sys_faccessat): Rename from sys_access and switch to
2559 faccessat's API. All uses changed.
2560 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2561 (magic_db): Rename from magic_file_p.
2562 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2563 char *, so that we don't have to test for file existence
2564 separately from opening the file for reading. This removes a race
2565 fixes a permission-checking problem, and simplifies the code.
2567 (file_p): Remove; no longer needed.
2569 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2571 Omit glyphs initialization at startup.
2572 * dispnew.c (glyphs_initialized_initially_p): Remove.
2573 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2574 (Fredraw_frame): Move actual code from here...
2575 (redraw_frame): ...to here. Add eassert. Adjust comment.
2576 (Fredraw_display): Use redraw_frame.
2577 * xdisp.c (clear_garbaged_frames): Likewise.
2579 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2581 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2582 passed to pint2str and pint2hrstr to be at most the size of the
2583 frame's decode_mode_spec_buffer. This avoids crashes with very
2584 large values of FIELD_WIDTH argument to decode_mode_spec.
2587 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2589 Fix a race with verify-visited-file-modtime (Bug#12863).
2590 Since at least 1991 Emacs has ignored an mtime difference of no
2591 more than one second, but my guess is that this was to work around
2592 file system bugs that were fixed long ago. Since the race is
2593 causing problems now, let's remove that code.
2594 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2595 whose time stamp is off by no more than a second. Insist that the
2596 file time stamps match exactly.
2598 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2600 * frame.h (struct frame): Convert external_tool_bar member to
2601 1-bit unsigned bitfield.
2602 * termhooks.h (struct terminal): Remove mouse_moved member since
2603 all users are long dead. Adjust comment on mouse_position_hook.
2605 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2607 Simplify by using FOR_EACH_FRAME here and there.
2608 * frame.c (next_frame, prev_frame, other_visible_frames)
2609 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2610 * w32term.c (x_window_to_scroll_bar): Likewise.
2611 * window.c (window_list): Likewise.
2612 * xdisp.c (x_consider_frame_title): Likewise.
2613 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2614 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2615 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2616 * xmenu.c (menubar_id_to_frame): Likewise.
2617 * xselect.c (frame_for_x_selection): Likewise.
2618 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2619 (x_window_to_menu_bar): Likewise.
2620 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2622 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2624 * data.c (Qdefalias_fset_function): Now static.
2626 Another tweak to vectorlike_header change.
2627 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2628 Remove, and replace all uses with ...
2629 (next_in_free_list, set_next_in_free_list):
2630 New functions, which respect C's aliasing rules better.
2632 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2634 * window.c (list4i): Rename from 'quad'. All uses changed.
2635 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2637 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2639 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2640 warning about mixing declarations and code in ISO C90.
2642 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2644 * window.c (Fsplit_window_internal): Set combination limit of
2645 new parent window to t iff Vwindow_combination_limit is t;
2646 fixing a regression introduced with the change from 2012-09-22.
2647 (Fset_window_combination_limit): Fix doc-string.
2649 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2651 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2652 amount when the scroll margins are too large. When scrolling
2653 backwards in the buffer, give up if cannot reach point or the
2654 scroll margin within a reasonable number of screen lines.
2655 Fixes point position in window under scroll-up/down-aggressively when
2656 point is positioned many lines beyond the window top/bottom.
2659 * ralloc.c (relinquish): If real_morecore fails to return memory
2660 to the system, don't crash; instead, leave the last heap
2661 unchanged and return. (Bug#12774)
2663 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2665 * lisp.h (AUTOLOADP): New macro.
2666 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2667 * data.c (Ffset): Remove special ad-advice-info handling.
2668 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2670 (Finteractive_form): Simplify.
2671 (Fquo): Don't insist on having at least 2 arguments.
2672 (Qdefalias_fset_function): New var.
2674 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2676 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2682 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2684 Fix recently introduced crash on MS-Windows (Bug#12839).
2685 * w32term.h (struct scroll_bar): Use convenient header.
2686 (SCROLL_BAR_VEC_SIZE): Remove.
2687 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2689 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2691 Tweak last vectorlike_header change.
2692 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2693 vectorlike object on the free list. This is introduced to avoid
2694 some (but not all) pointer casting and aliasing problems, see
2695 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2696 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2698 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2700 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2702 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2703 been removed, so remove them here also.
2705 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2707 * doc.c (Fdocumentation): Handle new property
2708 dynamic-docstring-function to replace the old ad-advice-info.
2710 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2712 * fns.c (Qeql, hashtest_eq): Now static.
2714 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

2717 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2718 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2719 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2721 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2723 Use same hash function for hashfn_profiler as for hash_string etc.
2724 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2725 * lisp.h (sxhash_combine): New inline function, with the contents
2726 of the old SXHASH_COMBINE.
2727 * profiler.c (hashfn_profiler): Use it, instead of having a
2728 special hash function containing a comparison that always yields 1.
2730 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2732 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2733 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2734 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2737 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2739 * image.c (xpm_make_color_table_h): Fix compiler error because
2740 make_hash_table changed.
2742 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2744 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2746 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2748 Use ad-hoc comparison function for the profiler's hash-tables.
2749 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2750 (make_log): Use them.
2751 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2752 call Fequal any more.

2761 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2762 (hash_lookup, hash_remove_from_table): Move assertion checking of
2763 hashfn result here. Check hash-equality before calling cmpfn.

2770 * print.c (print_object): Adjust to new hash-table struct.
2771 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2773 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2775 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2776 value of w32-scroll-lock-modifier is neither nil nor one of the
2777 known key modifiers. (Bug#12806)
2779 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2781 Shrink struct vectorlike_header to the only size field.
2782 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2784 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2785 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2786 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2787 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2788 information from the vector header. Adjust comment.

2798 (enum mem_type): Adjust comment.
2799 (NEXT_IN_FREE_LIST): New macro.
2800 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2801 (Fmake_bool_vector): Likewise.
2802 (struct large_vector): New type to represent allocation unit for
2803 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2804 (large_vectors): Change type to struct large_vector.
2805 (allocate_vector_from_block): Simplify.
2806 (PSEUDOVECTOR_NBYTES): Replace with...
2807 (vector_nbytes): ...new function. Adjust users.
2808 (sweep_vectors): Adjust processing of large vectors.
2809 (allocate_vectorlike): Likewise.
2810 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2811 Add easserts. Adjust XSETPVECTYPESIZE usage.
2812 (allocate_buffer): Use BUFFER_PVEC_INIT.
2813 (live_vector_p): Adjust to match large vector.
2814 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2815 * buffer.h (struct buffer): Add next member.
2816 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2818 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2819 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2820 (copy_hash_table): Adjust to match vector header change.
2821 * lread.c (defsubr): Use XSETPVECTYPE.
2822 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2823 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2824 (xvecsize): New command.
2826 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2828 * keyboard.c (event_to_kboard): Do not dereference
2829 frame_or_window field of SELECTION_REQUEST_EVENT
2830 and SELECTION_CLEAR_EVENT events (Bug#12814).
2831 * xterm.h (struct selection_input_event): Adjust comment.
2833 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2835 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2836 such as Scroll Lock, if the respective keys are treated as
2837 function keys, not as modifiers. This avoids destroying non-ASCII
2838 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2840 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2842 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2844 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2846 Restore some duplicate definitions (Bug#12814).
2847 This undoes part of the 2012-11-03 changes. Some people build
2848 with plain -g rather than with -g3, and they need the duplicate
2849 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2850 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2851 Define as macros, as well as as enums or as constants.
2853 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2855 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2856 to keypad keys (Bug#12816).
2858 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2860 Minor adjustments of recently-changed frame functions.
2861 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2862 known to be a frame (we're in the FRAMEP branch).
2863 * lisp.h (Qframep): Remove decl. frame.h declares this.
2864 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2865 since they're meant for Lisp fixnum values.
2867 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2869 * window.c (Fwindow_combination_limit): Revert to the only
2870 required argument and adjust docstring as suggested in
2871 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2872 by Martin Rudalics <rudalics@gmx.at>.
2874 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2876 Widely used frame validity and checking functions.
2877 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2878 * frame.c (decode_live_frame, decode_any_frame): New functions.
2879 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2880 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2881 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2882 (Fframe_pointer_visible_p): Use decode_any_frame.
2883 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2884 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2885 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2886 (Fframe_focus): Likewise. Allow zero number of arguments.
2888 (frame_buffer_list, frame_buffer_predicate): Remove.
2889 * lisp.h (frame_buffer_predicate): Remove prototype.
2890 * buffer.c (Fother_buffer): Use decode_any_frame.
2891 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2892 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2893 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2894 (Fclose_font, Ffont_info): Use decode_live_frame.
2895 * fontset.c (check_fontset_name): Likewise.
2896 * terminal.c (Fframe_terminal): Likewise.
2897 * w32fns.c (check_x_frame): Likewise.
2898 * window.c (Fminibuffer_window, Fwindow_at)
2899 (Fcurrent_window_configuration): Likewise.
2900 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2901 Likewise. Allow zero number of arguments. Adjust docstring.
2902 * dispnew.c (Fredraw_frame): Likewise.
2903 * xfaces.c (frame_or_selected_frame): Remove.
2904 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2905 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2906 (Fframe_face_alist): Use decode_live_frame.
2907 * xfns.c (check_x_frame): Likewise.
2909 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2911 * window.c (quad): New function.
2912 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2913 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2914 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2915 (Fwindow_line_height): Use it.
2916 (Fwindow_fringes): Use list3.
2917 (Fwindow_scroll_bars): Use list4.
2918 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2919 (Fwindow_combination_limit): Allow zero number of arguments.
2921 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2923 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2925 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2926 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2927 file descriptor 2 for standard error. (Bug#12805)
2929 2012-11-05 Chong Yidong <cyd@gnu.org>
2931 * process.c (wait_reading_process_output): Revert previous change.
2933 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2935 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2936 This removes code that has been obsolete since around 1990.
2937 * callproc.c (Fcall_process):
2939 * process.c (create_process):
2940 * term.c (dissociate_if_controlling_tty):
2941 Assume setsid exists.
2942 * callproc.c (child_setup): Assume setpgid exists and behaves as
2943 per POSIX.1-1988 or later.
2944 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2945 * emacs.c (shut_down_emacs):
2946 * sysdep.c (sys_suspend, init_foreground_group):
2947 Assume getpgrp behaves as per POSIX.1-1998 or later.
2948 * msdos.c (setpgrp): Remove.
2949 (tcgetpgrp, setpgid, setsid): New functions.
2950 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2951 * term.c (no_controlling_tty): Remove; unused.
2952 * w32proc.c (setpgrp): Remove.
2953 (setsid, tcgetpgrp): New functions.
2955 Simplify by assuming __fpending.
2956 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2957 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2958 Do not assume that __fpending's result fits in int.
2960 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2962 Remove EMACS_OUTQSIZE+sleep hack.
2963 * dispnew.c (update_frame_1): Remove hack for terminals slower
2964 than 2400 bps, which throttled Emacs by having it sleep.
2965 This code hasn't worked since at least 2007, when the multi-tty stuff
2966 was added, and anyway those old terminals are long dead.
2967 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2968 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2970 Fix data-loss with --version (Bug#9574).
2971 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2972 as we can't assume that emacs_strerror is initialized, and strerror
2973 is good enough here.
2974 (main): Invoke atexit earlier, to catch earlier instances of
2975 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2977 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2979 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2980 (keyDown): Remap keypad keys to X11 virtual key codes.
2982 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2984 Fix data-loss with --batch (Bug#9574).
2985 * emacs.c: Include <close-stream.h>.
2986 (close_output_streams): New function.
2987 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2988 and handles errors appropriately.
2989 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2992 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2993 The symptom is a diagnostic "GLib-WARNING **: In call to
2994 g_spawn_sync(), exit status of a child process was requested but
2995 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2996 waitpid(), so exit status can't be returned." The diagnostic
2997 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2998 The real bug is a race condition between Emacs and glib: Emacs
2999 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3000 so that glib can't find it. Work around the bug by invoking
3001 waitpid only on subprocesses that Emacs itself creates.
3002 * process.c (create_process, record_child_status_change):
3003 Don't use special value -1 in pid field, as the caller now must
3004 know the pid rather than having the callee infer it.
3005 The inference was sometimes incorrect anyway, due to another race.
3006 (create_process): Set new 'alive' member if child is created.
3007 (process_status_retrieved): New function.
3008 (record_child_status_change): Use it.
3009 Accept negative 1st argument, which means to wait for the
3010 processes that Emacs already knows about. Move special-case code
3011 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3012 processes that have already been waited for, by testing and
3013 clearing new 'alive' member.
3014 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3015 now does this internally.
3016 (handle_child_signal): Let record_child_status_change do all
3017 the work, since we do not want to reap all exited child processes,
3018 only the child processes that Emacs itself created.
3019 * process.h (Lisp_Process): New boolean member 'alive'.
3021 Omit duplicate definitions no longer needed with gcc -g3.
3022 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3023 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3024 Define only as macros. There's no longer any need to also define
3025 these symbols as enums or as constants, since we now assume
3026 gcc -g3 when debugging.
3028 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3030 * lisp.mk: Adjust comments to the fact that term/internal is now
3031 loaded from loadup.el.
3033 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3034 (msdos_fatal_signal): New function.
3035 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3038 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3039 for GCC versions before 4.
3040 (emacs_raise): Define to call msdos_fatal_signal.
3042 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3043 iterator when starting in the middle of a display or overlay
3046 2012-11-03 Chong Yidong <cyd@gnu.org>
3048 * process.c (wait_reading_process_output): Clean up the last
3051 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3053 * process.c (wait_reading_process_output): Avoid a race condition
3054 with SIGIO delivery (Bug#11536).
3056 2012-11-03 Chong Yidong <cyd@gnu.org>
3058 * buffer.c (cursor_type): Untabify docstring.
3060 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3062 * frame.h (struct frame): Drop can_have_scroll_bars member
3063 which is meaningless for a long time. Adjust comments.
3064 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3065 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3067 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3069 * window.c (decode_next_window_args): Update window arg after
3070 calling decode_live_window and so fix crash reported at
3071 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3072 by Juanma Barranquero <lekktu@gmail.com>.
3073 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3074 * font.c (Ffont_at): Likewise.
3076 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3078 * widget.c (resize_cb): New function.
3079 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3080 (EmacsFrameResize): Check if all is up to date before changing frame
3083 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3085 Implement backtrace output for fatal errors on MS-Windows.
3086 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3087 (BACKTRACE_LIMIT_MAX): New macro.
3088 (w32_backtrace): New function.
3089 (emacs_abort): Use w32_backtrace when the user chooses not to
3090 attach a debugger. Update the text of the abort dialog.
3092 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3094 Window-related stuff cleanup here and there.
3095 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3096 Use decode_any_window.
3097 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3098 * xdisp.c (Fformat_mode_line): Likewise.
3099 * font.c (Ffont_at): Use decode_live_window.
3100 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3101 * window.c (decode_next_window_args): Likewise.
3102 (decode_any_window): Remove static.
3103 * window.h (decode_any_window): Add prototype.
3104 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3105 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3108 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3110 Remove pad from struct input_event.
3111 * termhooks.h (struct input_event): Remove padding field.
3113 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3114 member is never cons for a long time. Adjust comment.
3115 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3116 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3117 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3118 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3120 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3122 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3124 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3126 Fix crash when using Emacs as commit editor for git (Bug#12697).
3127 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3128 and it is configured in conf_post.h.
3129 (Fcall_process): Don't invoke both setsid and setpgid; the former
3130 is enough, if it exists.
3131 * callproc.c (Fcall_process, child_setup):
3132 * process.c (create_process): Use setpgid.
3133 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3135 * dispnew.c (init_display): Initialize the foreground group
3136 if we are running a tty display.
3137 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3138 * lisp.h (init_foreground_group): New decl.
3139 * sysdep.c (inherited_pgroup): New static var.
3140 (init_foreground_group, tcsetpgrp_without_stopping)
3141 (narrow_foreground_group, widen_foreground_group): New functions.
3142 (init_sys_modes): Narrow foreground group.
3143 (reset_sys_modes): Widen foreground group.
3145 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3147 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3149 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3151 * minibuf.c (read_minibuf): Restore current buffer since
3152 choose_minibuf_frame calling Fset_frame_selected_window may
3153 change it (Bug#12766).
3155 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3157 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3159 2012-10-30 Kenichi Handa <handa@gnu.org>
3161 * font.c (Ffont_at): If WINDOW is specified and it is not
3162 displaying the current buffer, signal an error.
3164 2012-10-29 Daniel Colascione <dancol@dancol.org>
3166 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3167 In preparation for fixing bug#12739, move these functions from
3170 * coding.h, coding.c: ... to here, and compile them only when
3171 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3172 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3174 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3176 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3177 (timer_loop, getitimer, setitimer): Use it instead of
3178 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3180 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3183 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3185 * nsterm.m (NO_APPDEFINED_DATA): New define.
3186 (last_appdefined_event_data): New variable
3187 (last_appdefined_event): Remove.
3188 (ns_select): Initialize t from last_appdefined_event_data instead
3189 of [last_appdefined_event data1].
3190 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3191 remove last_appdefined_event (Bug#12698).
3193 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3195 * frame.c (x_set_font): Catch internal error.
3197 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3199 Avoid overflow in w32 implementation of interval timers.
3200 When possible, for ITIMER_PROF count only times the main thread
3202 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3203 'volatile ULONGLONG' types. All the other data which was
3204 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3205 (GetThreadTimes_Proc): New typedef.
3206 (w32_get_timer_time): New function, returns a suitable time value
3208 (timer_loop): Enter critical section when accessing ULONGLONG
3209 values of the itimer_data struct, as these accesses are no longer
3210 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3211 Remove unused variable.
3212 (init_timers): Initialize s_pfn_Get_Thread_Times.
3213 (start_timer_thread): Don't assign itimer->caller_thread here.
3214 (getitimer): Assign itimer->caller_thread here.
3215 (setitimer): Always call getitimer to get the value of ticks_now.
3216 (sys_spawnve): Avoid compiler warning about format mismatch.
3218 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3220 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3221 mouse movement events if the menu bar is active. This avoids
3222 producing a busy "hour-glass" cursor by Windows if the mouse
3223 pointer is positioned over a tooltip shown for some menu item.
3225 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3227 Don't assume process IDs fit in int.
3228 * emacs.c (shut_down_emacs) [!DOS_NT]:
3229 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3230 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3231 Use pid_t, not int, to store process IDs, as 'int'
3232 is not wide enough on a few platforms (e.g., AIX and IRIX).
3234 2012-10-23 Kenichi Handa <handa@gnu.org>
3236 The following change is to make face-font-rescale-alist work
3237 correctly for non-ASCII fonts.
3239 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3240 (font_open_for_lface): Handle Vface_font_rescale_alist.
3242 2012-10-23 Chong Yidong <cyd@gnu.org>
3244 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.

3727 * image.c: Permanent fix for JPEG compilation issue --- limit
3728 jpeglib `boolean' redefinition to Cygwin builds.
3730 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3732 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3734 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3737 2012-10-08 Daniel Colascione <dancol@dancol.org>
3739 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3740 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3741 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3742 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3743 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3744 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3745 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3746 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3747 now a supported configuration.
3749 * Makefile.in: consolidate image variables into LIBIMAGE; add
3750 W32_OBJ and W32_LIBS. Compile new files.
3753 (_DebPrint) declare tracing facility for W32 debugging. We need
3754 to unify tracing later.
3756 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3757 unconditional use of W32 Unicode functions. Cygwin runs only on
3758 100% Unicode operating systems.
3760 * cygw32.c: New file. Define Cygwin-specific facilities.
3761 (Fcygwin_convert_path_to_windows)
3762 (Fcygwin_convert_path_from_windows): New user functions for
3763 accessing Cygwin path-munging routines.
3765 * cygw32.h: New file.
3766 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3767 UTF-16LE strings temporarily inside non-Lisp-visible string
3770 (w32_strerror): Just what it says on the tin.
3772 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3773 also run for Cygwin; both systems have the same problem with using
3774 GUI facilities in a forked child. Also call syms_of_cygw32,
3775 syms_of_w32select in correct places.
3777 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3778 needs fork-then-exec for daemon launching.
3780 * font.h: Include frame.h.
3782 * image.c: Use the image library cache machinery only when we're
3783 compiling for native WINDOWSNT; Cygwin can use shared libraries
3784 like any other Unixlike system.
3786 * keyboard.c: Clarify a comment regarding the input loop.
3788 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3789 functions directly instead of trying to detect at runtime that our
3790 host operating system supports them. We make this change for two
3791 reasons: Cygwin lacks support for the multibyte character
3792 conversion functions used by the legacy menu code, and Cygwin
3793 never needs to rely on non-Unicode APIs.
3795 * unexw32.c (hinst): Declare extern.
3797 * w32.c: Change header order;
3798 (w32_strerror): Move to w32fns.c because we need it for
3799 non-WINDOWSNT builds.
3801 * w32.h: Add #error macro to make sure we don't include w32.h for
3802 Cygwin builds. Remove w32select declarations.
3804 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3805 w32fns.c. w32console.c is WINDOWSNT-only.
3807 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3808 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3810 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3811 (w32_major_version, w32_minor_version, w32_build_number)
3812 (os_subtype, sound_type): Define here
3813 (w32_defined_color): Make color parameter const for consistency
3814 with other _defined_color functions.
3815 (w32_createwindow): Unconditionally call w32_init_class instead of
3816 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3817 through the code is complex and unnecessary because class
3818 registration is practically free.
3819 (w32_name_of_message): New EMACSDEBUG-only function.
3820 (Fset_message_beep): Move here
3821 (Fx_open_connection): Require that the display name for Windows be
3822 "w32" for consistency, emacsclient disambiguation, and maybe, one
3823 day, multi-window-system support.
3824 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3825 Cygwin files for W32 GUI facilities, since these clearly don't
3826 expect Cygwin names.
3827 (_DebPrint): Define.
3828 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3829 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3830 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3831 (w32_last_error): Remove.
3833 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3835 * w32heap.c (syspage_mask): Declare here.
3836 (cache_system_info): Remove.
3838 * w32inevt.c (faked_key): Define globally, not statically.
3839 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3840 (w32_console_toggle_lock_key): Move to w32fns.c.
3842 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3844 * w32proc.c (_DebPrint): Move to w32fns.c.
3845 * w32select.c: Include string.h, stdio.h for Cygwin.
3846 * w32select.h: New File.
3848 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3850 (w32_message_fd): New variable. Under Cygwin, holds the file
3851 descriptor the system used to tell us about pending thread
3854 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3855 that prevented compilation under non-WINDOWSNT systems.
3857 (w32_initialize): Open /dev/windows and assign it to
3858 w32_message_fd. Provide w32 feature.
3860 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3861 (WM_EMACS_INPUT_READY): add.
3862 (prepend_msg, w32_message_fd): Declare globally.
3865 (keyboard_handle): Use only when WINDOWSNT.
3866 (notify_msg_ready): New function. Posts a message to the main
3867 thread's message queue under CYGWIN, which wakes up the main
3868 thread from select(2) by making the /dev/windows file descriptor
3869 ready. Under WINDOWSNT, it sets an event the same way the old
3872 (post, prepend_msg): Actually call notify_msg_ready instead of
3873 setting the input event directly.
3875 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3877 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3878 but it still has blocs in it, don't return it to the system,
3879 instead of aborting. (Bug#12402)
3881 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3883 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3885 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3886 MAC_OS_X_VERSION_10_6.
3887 (syms_of_nsterm): Remove comment about Panther and above for
3889 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3890 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3891 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3893 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3894 MAC_OS_X_VERSION_10_4.
3896 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3897 MAC_OS_X_VERSION_10_2.
3899 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3901 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3902 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3904 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3905 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3906 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3907 Remove ns_in_resize check.
3908 (ns_clear_frame_area): Remove resize handle code.
3910 * nsfns.m (ns_in_resize): Remove.
3911 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3912 Remove ns_in_resize check.
3914 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3916 Improve sys_siglist detection.
3917 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3918 defined as a macro, as is done in Solaris.
3919 (sys_siglist_entries): New macro.
3920 (save_strsignal): Use it.
3921 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3922 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3924 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3926 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3927 fullscreen/Fullscreen.
3929 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3930 tobar_height is new.
3932 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3933 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3934 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3935 (windowDidResize:): Check for correct window if old style fullscreen.
3936 Capitalize word in comment. Remove incorrect comment.
3937 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3938 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3939 error in drawing background.
3940 (toggleFullScreen:): Remove comment. Rearrange calls.
3941 Set toolbar values to zero, save old height in tobar_height.
3942 Restore tool bar height when leaving fullscreen.
3943 (canBecomeMainWindow): New function.
3945 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3947 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3949 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3951 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3953 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3954 that time stamps of directories could also be changed.
3955 Don't request the too broad GENERIC_WRITE, only the more restrictive
3956 FILE_WRITE_ATTRIBUTES access rights.
3958 * fileio.c (Fset_file_times): Special-case ignoring errors for
3959 directories only on MSDOS, not on MS-Windows.
3961 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3963 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3965 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3967 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3968 see whether CreateFile failed.
3970 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3972 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3973 to avoid similar races.
3974 * keyboard.c (pending_signals): Now bool, not int.
3976 Port timers to OpenBSD, plus check for timer failures.
3977 OpenBSD problem reported by Han Boetes.
3978 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3980 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3981 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3982 like OpenBSD, which has timer_settime but does not declare it.
3983 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3984 whether to use itimerspec-related primitives. All uses of
3985 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3987 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3989 * profiler.c (handle_profiler_signal): Fix a malloc race
3990 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3992 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3994 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3996 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3998 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3999 consistent with the change in return value of 'safe_strsignal'.
4001 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4003 Prefer plain 'static' to 'static inline' (Bug#12541).
4004 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4005 (bidi_set_sor_type, bidi_push_embedding_level)
4006 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4007 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4008 (bidi_cache_search, bidi_cache_ensure_space)
4009 (bidi_cache_iterator_state, bidi_cache_find)
4010 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4011 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4012 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4013 Now 'static', not 'static inline'.
4015 Count overruns when profiling; change units to ns.
4016 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4017 Give extra weight to samples after overruns, to attempt to count
4018 the time more accurately.
4019 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4020 the underlying primitives nominally do ns.
4021 (Fprofiler_cpu_start): Document the change. Mention that
4022 the sampling intervals are only approximate.
4024 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4026 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4028 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4029 case for the special 0 coding-system.
4031 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4032 (Fmake_overlay): Remove redundant tests.
4033 (fix_start_end_in_overlays): Remove redundant recentering.
4035 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4037 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4038 Update dependencies.
4040 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4042 Fix a malloc race condition involving strsignal.
4043 A signal can arrive in the middle of a malloc, and Emacs's signal
4044 handler can invoke strsignal, which can invoke malloc, which is
4045 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4046 Fix it by altering the signal handler so that it does not invoke
4048 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4049 * process.c (status_message): Use const pointer, in case strsignal
4050 is #defined to safe_strsignal.
4051 * sysdep.c (sys_siglist, init_signals): Always define and
4052 initialize a substitute sys_siglist if the system does not define
4053 one, even if HAVE_STRSIGNAL.
4054 (safe_strsignal): Rename from strsignal. Always define,
4055 using sys_siglist. Return a const pointer.
4056 * syssignal.h (safe_strsignal): New decl.
4057 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4059 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4061 * w32proc.c (timer_loop): Fix code that waits for timer
4062 expiration, to avoid high CPU usage.
4064 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4066 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4067 (sweep_weak_table): Remove redundant prototypes.
4069 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4071 * emacs.c: Move the inclusion of TERM_HEADER after including
4072 windows.h on WINDOWSNT. This avoids compilation problems with
4075 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4077 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4078 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4079 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4080 as the previous version used 'void *'.
4082 * ralloc.c (ROUNDUP): Fix last change.
4083 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4086 * w32proc.c <disable_itimers>: New static flag.
4087 (init_timers): Initialize it to zero, after creating the critical
4088 sections used by the timer threads.
4089 (term_timers): Set to 1 before deleting the critical sections.
4090 (getitimer, setitimer): If disable_itimers is non-zero, return an
4091 error indication without doing anything. Reported by Fabrice
4092 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4093 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4095 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4098 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4099 term_ntproc after all the other bookkeeping, to get timers working
4100 as long as possible.
4102 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4104 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4105 Suggested by Juri Linkov in
4106 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4108 Prefer plain 'static' to 'static inline' (Bug#12541).
4109 With static functions, modern compilers inline pretty well by
4110 themselves; advice from programmers often hurts as much as it helps.
4111 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4112 this change shrinks the text size of the Emacs executable by 1.1%
4113 without affecting CPU significantly in my benchmark.
4114 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4407 (handle_profiler_signal): Rename from sigprof_handler_1,
4408 for consistency with other handlers. Do not check whether
4409 cpu_log is a hash-table if garbage collecting, since it

4412 for consistency with other handlers.
4413 (setup_cpu_timer): New function, with much of what used to be in

4415 Prefer timer_settime if available, and prefer
4416 thread cputime clocks, then process cputime clocks, then
4417 monotonic clocks, to the old realtime clock. Use make_timeval
4418 to round more-correctly when falling back to setitimer.
4419 (Fprofiler_cpu_start): Use it.
4420 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4427 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4428 in profiler.c, since sysdep.c now uses it.
4430 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4486 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4487 Since this stuff is now private to charset.c, there's no need for
4488 a public macro and no need to inline by hand.

4568 install term_ntproc as a signal handler for SIGABRT, as that
4569 should be done by the dumped Emacs.

4629 (compute_motion, vmotion, Fvertical_motion):
4630 Use bool for booleans.
4632 2012-09-24 Chong Yidong <cyd@gnu.org>
4634 * chartab.c (Fset_char_table_default): Obsolete function removed.
4636 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4638 Move pid_t related decls out of lisp.h.
4639 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4640 (interruptible_wait_for_termination):
4641 Move these decls from lisp.h to syswait.h, since they use pid_t.
4642 Needed on FreeBSD; see Herbert J. Skuhra in
4643 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4644 * callproc.c: Include syswait.h.
4646 gnutls.c, gtkutil.c: Use bool for boolean.
4647 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
4648 (emacs_gnutls_handle_error):
4649 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)
4650 (xg_hide_tooltip, xg_create_frame_widgets)

4659 (update_frame_tool_bar, free_frame_tool_bar):
4660 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
4661 * nsmenu.m (ns_update_menubar):
4662 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4663 * xfns.c (Fx_show_tip) [USE_GTK]:
4664 Use bool for boolean.
4665 * gtkutil.c (xg_update_frame_menubar):
4666 * xmenu.c (update_frame_menubar):
4667 Return void, not int, since caller ignores return value.
4668 * gtkutil.c (xg_change_toolbar_position):
4671 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4673 * makefile.w32-in (BLOCKINPUT_H): Remove.

4690 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4692 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4693 fatal_error_backtrace.
4695 * w32proc.c (sys_kill): Undo last change: don't do anything when
4696 invoked to deliver SIGABRT to our own process. This is now
4697 handled by emacs_raise.
4699 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4701 * w32term.c (w32_read_socket): Remove leftover reference to
4702 interrupt_input_pending.
4704 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4706 Do not use SA_NODEFER.
4707 Problem reported by Dani Moncayo in
4708 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4710 * sysdep.c (emacs_abort): Do not reset signal handler.
4711 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4712 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4713 wanted even on POSIXish hosts, and it doesn't work on Windows.
4715 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4717 * xterm.c (x_term_init): Call fixup_locale before and after calling
4718 gtk_init (Bug#12392).
4720 2012-09-23 Chong Yidong <cyd@gnu.org>
4722 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4723 Vdynamic_library_alist.
4725 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4726 (Fgnutls_available_p): Caller changed.
4728 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4729 (Flibxml_parse_xml_region): Likewise.
4731 * dispextern.h (struct image_type): Remove arg from init function.
4733 * image.c (Finit_image_library, lookup_image_type)
4734 (define_image_type): Remove now-unneeded second arg.
4735 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4736 (init_tiff_functions, init_gif_functions, init_svg_functions):
4737 Arglist and w32_delayed_load calling convention changed.
4738 (gs_type): Remove init_gs_functions; there is no such function.
4739 (valid_image_p, make_image): Fix caller to lookup_image_type.
4741 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4743 Simplify and avoid signal-handling races (Bug#12471).
4745 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4746 Avoid recursive loop if there's a fatal error in the function itself.
4747 * atimer.c (pending_atimers):
4748 * blockinput.h: Don't include "atimer.h"; no longer needed.
4749 (interrupt_input_pending): Remove. All uses removed.
4750 pending_signals now counts both atimers and ordinary interrupts.
4751 This is less racy than having three separate pending-signal flags.
4752 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4754 Rename from their upper-case counterparts BLOCK_INPUT,
4755 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4756 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4757 This makes it easier to access volatile variables more accurately.
4758 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4759 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4760 that's more reliable if the code is buggy and sets
4761 interrupt_input_blocked to a negative value. All uses changed.
4762 * atimer.c (deliver_alarm_signal):
4763 Remove. No need to deliver this to the parent; any thread can
4764 handle this signal now. All uses replaced by underlying handler.
4765 * atimer.c (turn_on_atimers):
4766 * dispnew.c (handle_window_change_signal):
4767 * emacs.c (handle_danger_signal):
4768 * keyboard.c (kbd_buffer_get_event):
4769 Don't reestablish signal handler; not needed with sigaction.
4770 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4772 Rework to avoid unnecessary accesses to volatile variables.
4773 (UNBLOCK_INPUT_TO): Now a function.
4774 (totally_unblock_input, unblock_input): New decls.
4775 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4776 (init_data): Remove. Necessary stuff now done in init_signal.
4777 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4778 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4779 (fatal_error_code): Remove; no longer needed.
4780 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4781 it doesn't always backtrace. All uses changed. No need to reset
4782 signal to default, since sigaction and/or die does that for us now.
4783 Use emacs_raise (FOO), not kill (getpid (), FOO).
4784 (main): Check more-accurately whether we're dumping.
4785 Move fatal-error setup to sysdep.c
4786 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4787 * gtkutil.c (xg_get_file_name, xg_get_font):
4788 Remove no-longer-needed signal-mask manipulation.
4789 * keyboard.c, process.c (POLL_FOR_INPUT):
4790 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4791 * keyboard.c (read_avail_input): Remove.
4792 All uses replaced by gobble_input.
4793 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4794 (kbd_buffer_store_event_hold, gobble_input):
4795 (record_asynch_buffer_change) [USABLE_SIGIO]:
4796 (store_user_signal_events):
4797 No need to mess with signal mask.
4798 (gobble_input): If blocking input and there are terminals, simply
4799 set pending_signals to 1 and return. All hooks changed to not
4800 worry about whether input is blocked.
4801 (process_pending_signals): Clear pending_signals before processing
4802 them, in case a signal comes in while we're processing.
4803 By convention callers now test pending_signals before calling us.
4804 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4805 New functions, to support changes to blockinput.h.
4806 (handle_input_available_signal): Now extern.
4807 (reinvoke_input_signal): Remove. All uses replaced by
4809 (quit_count): Now volatile, since a signal handler uses it.
4810 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4811 All callers changed. Block SIGINT only if not already blocked.
4812 Clear sigmask reliably, even if Fsignal returns, which it can.
4813 Omit unnecessary accesses to volatile var.
4814 (quit_throw_to_read_char): No need to restore sigmask.
4815 * keyboard.c (gobble_input, handle_user_signal):
4816 * process.c (wait_reading_process_output):
4817 Call signal-handling code rather than killing ourselves.
4818 * lisp.h: Include <float.h>, for...
4819 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4820 (pending_signals): Now volatile.
4821 (syms_of_data): Now const if IEEE floating point.
4822 (handle_input_available_signal) [USABLE_SIGIO]:
4823 (terminate_due_to_signal, record_child_status_change): New decls.
4824 * process.c (create_process): Avoid disaster if memory is exhausted
4825 while we're processing a vfork, by tightening the critical section
4827 (send_process_frame, process_sent_to, handle_pipe_signal)
4828 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4830 (send_process): No need for setjmp/longjmp any more, since the
4831 SIGPIPE stuff is now gone. Instead, report an error if errno
4833 (record_child_status_change): Now extern. PID and W are now args.
4834 Return void, not bool. All callers changed.
4835 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4836 Remove. All uses removed. This bug should be fixed now in a
4838 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4839 and record the child status change directly. This avoids the
4840 need to futz with the signal mask.
4841 (process_fatal_action): Move here from emacs.c.
4842 (emacs_sigaction_flags): New function, containing
4843 much of what used to be in emacs_sigaction_init.
4844 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4845 caught by emacs, to make races less likely.
4846 (deliver_process_signal): Rename from handle_on_main_thread.
4848 (BACKTRACE_LIMIT_MAX): Now at top level.
4849 (thread_backtrace_buffer, threadback_backtrace_pointers):
4851 (deliver_thread_signal, deliver_fatal_thread_signal):
4852 New functions, for more-accurate delivery of thread-specific signals.
4853 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4854 (deliver_arith_signal): Handle in this thread, not
4855 in the main thread, since it's triggered by this thread.
4856 (maybe_fatal_sig): New function.
4857 (init_signals): New arg DUMPING so that we can be more accurate
4858 about whether we're dumping. Caller changed.
4859 Treat thread-specific signals differently from process-general signals.
4860 Block all signals while handling fatal error; that's safer.
4861 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4863 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4864 Ignore SIGPIPE unless batch.
4865 (emacs_backtrace): Output backtrace for the appropriate thread,
4866 which is not necessarily the main thread.
4867 * syssignal.h: Include <stdbool.h>.
4868 (emacs_raise): New macro.
4869 * xterm.c (x_connection_signal): Remove; no longer needed
4870 now that we use sigaction.
4871 (x_connection_closed): No need to mess with sigmask now.
4872 (x_initialize): No need to reset SIGPIPE handler here, since
4873 init_signals does this for us now.
4875 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4877 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4878 background rect may be larger (Bug#12245).
4880 2012-09-23 Chong Yidong <cyd@gnu.org>
4882 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4884 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4886 * .gdbinit: Just stop at fatal_error_backtrace.
4887 See Stefan Monnier's request in
4888 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4889 Remove no-longer-used query of system type.
4891 2012-09-22 Chong Yidong <cyd@gnu.org>
4893 * search.c (Freplace_match): Doc fix (Bug#12325).
4895 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4897 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4898 (Fline_end_position): Doc fix.
4900 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4902 2012-09-22 Chong Yidong <cyd@gnu.org>
4904 * dispextern.h (struct image_type): Add new slot, storing a type
4905 initialization function.
4907 * image.c (define_image_type): Call the image initializer function
4908 if it is defined. Arguments and return value changed.
4909 (valid_image_p, make_image): Callers changed.
4910 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4911 (gif_type, imagemagick_type, svg_type, gs_type):
4912 Add initialization functions.
4913 (Finit_image_library): Call lookup_image_type.
4914 (CHECK_LIB_AVAILABLE): Macro deleted.
4915 (lookup_image_type): Call define_image_type here, rather than via
4916 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4917 (syms_of_image): Move define_image_type calls for xbm_type and
4918 pbm_type to lookup_image_type.
4920 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4922 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4923 'idle_timers' from here ...
4924 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4925 lists, to avoid infloops when the timer does something stupid,
4926 like reinvoke itself with the same or smaller time-out.
4929 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4931 * window.c (Fsplit_window_internal): Handle only Qt value of
4932 Vwindow_combination_limit separately.
4933 (Qtemp_buffer_resize): New symbol.
4934 (Vwindow_combination_limit): New default value.
4937 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4939 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4940 the new overlay string. (Bug#10159)
4942 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4944 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4945 or that fprintf is async-signal-safe. POSIX doesn't require
4948 2012-09-22 Chong Yidong <cyd@gnu.org>
4950 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4953 2012-09-22 Kenichi Handa <handa@gnu.org>
4955 * composite.c (composition_reseat_it): Handle the case that a
4956 grapheme cluster is not covered by a single font (Bug#12352).
4958 2012-09-21 Chong Yidong <cyd@gnu.org>
4960 * image.c (define_image_type): Avoid adding duplicate types to
4961 image_types (Bug#12463). Suggested by Jörg Walter.
4963 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4965 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4966 (print_load_command_name): Add case LC_DATA_IN_CODE.
4967 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4969 2012-09-21 Glenn Morris <rgm@gnu.org>
4971 * eval.c (Frun_hook_with_args_until_success)
4972 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4974 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4976 * fileio.c (Ffile_selinux_context): Only call freecon when
4977 lgetfilecon succeeded.
4978 (Fset_file_selinux_context): Likewise. (Bug#12444)
4980 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4982 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4983 reordering, locate the cursor by calling set_cursor_from_row; if
4984 that fails, clear the desired glyph matrix before returning a
4985 failure indication to the caller. Fixes leaving garbled display
4986 when fast scrolling with a down-key. (Bug#12403)
4987 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4988 scrolling through multibyte text.
4990 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4992 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4993 calling mark_vectorlike since that's the one that marks the window.
4994 (mark_discard_killed_buffers): Mark the final cdr.
4995 * window.h (struct window): Move prev/next_buffers to the
4996 non-standard fields.
4997 * window.c (make_window): Initialize prev/next_buffers manually.
4999 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5001 Omit unused arg EXPECTED from socket hooks.
5002 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5003 * nsterm.m (ns_term_init):
5004 * termhooks.h (struct terminal.read_socket_hook):
5005 * w32inevt.c (w32_console_read_socket):
5006 * w32term.c (w32_read_socket):
5007 * xterm.c (XTread_socket):
5008 Omit unused arg EXPECTED. All callers changed.
5009 (store_user_signal_events): Return void, not int, since callers no
5010 longer care about the return value. All uses changed.
5012 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5014 * w32gui.h (XParseGeometry): Do not declare.
5016 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5018 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5019 Ignore 'expected'. See Eli Zaretskii in
5020 <http://bugs.gnu.org/12471#8> (last line).
5022 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5023 (XParseGeometry): Now static. Substitute extremal values for
5024 values that are out of range.
5026 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5028 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5030 * nsfns.m (XParseGeometry): Remove.
5031 (Fx_create_frame): Call x_set_offset to correctly interpret
5032 top_pos in geometry.
5034 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5035 (Fx_parse_geometry): If there is a space in string, call
5036 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5038 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5040 * search.c (scan_buffer): Use character positions in calls to
5041 region_cache_forward and region_cache_backward, not byte
5042 positions. (Bug#12196)
5044 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5045 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5047 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5048 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5049 emacs_blocked_malloc, now deleted.
5051 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5053 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5054 The workaround was for improving performance on Solaris 2.4, but
5055 is getting in the way now. Emacs will still work if someone is
5056 still running Solaris 2.4 in a museum somewhere; Sun dropped
5057 support for Solaris 2.4 in 2003.
5058 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5059 * process.c (create_process) [HAVE_WORKING_VFORK]:
5060 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5061 since Emacs no longer uses vfork on that platform.
5063 2012-09-17 Glenn Morris <rgm@gnu.org>
5065 * emacs.c: Use COPYRIGHT.
5067 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5069 Remove configure's --without-sync-input option (Bug#12450).
5070 When auditing signal-handling in preparation for cleaning it up,
5071 I found that SYNC_INPUT has race conditions and would be a real
5072 pain to fix. Since it's an undocumented and deprecated
5073 configure-time option, now seems like a good time to remove it.
5074 Also see <http://bugs.gnu.org/11080#16>.
5075 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5076 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5077 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5078 (malloc_hysteresis):
5079 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5080 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5081 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5082 (dont_register_blocks, bytes_used_when_reconsidered)
5083 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5084 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5085 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5086 Remove. All uses removed.
5087 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5088 implementation, one that depends on whether the new macro
5089 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5091 * atimer.c (run_timers, handle_alarm_signal):
5092 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5093 (handle_async_input, process_pending_signals)
5094 (handle_input_available_signal, init_keyboard):
5095 * nsterm.m (ns_read_socket):
5096 * process.c (wait_reading_process_output):
5097 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5098 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5100 * xterm.c (XTread_socket):
5102 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5103 * eval.c (handling_signal): Remove. All uses removed.
5104 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5105 All uses replaced with the SYNC_INPUT version.
5106 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5108 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5111 * font.c (Ffont_shape_gstring): Remove unused local.
5113 2012-09-16 Glenn Morris <rgm@gnu.org>
5115 * Makefile.in (clean): No longer run nextstep's clean.
5117 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5119 (ns-app): Move here from ns.mk, and simplify.
5120 (clean): Simplify nextstep entry.
5121 * ns.mk: Remove file.
5123 2012-09-17 Kenichi Handa <handa@gnu.org>
5125 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5126 not covert the last few charactes.
5128 2012-09-16 Kenichi Handa <handa@gnu.org>
5130 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5131 here, but just check the validity of glyphs in the glyph-string.
5133 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5135 * window.c (Fwindow_parameter, Fset_window_parameter):
5136 Accept any window as argument (Bug#12452).
5138 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5140 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5141 to ns_term_init to avoid memory leak.
5143 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5144 explicit retain/release.
5145 (ns_term_init): Only allow one display. Initialize outerpool and
5148 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5150 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5151 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5152 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5153 the Microsoft problem in a different way, by altering ../nt/config.nt.
5155 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5170 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5171 by lisp.h. This completes removal of setjmp.h inclusion
5172 erroneously announced in the previous commit. (Bug#12446)
5174 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5177 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5178 not defined as a macro. The latter happens on MS-Windows.
5181 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5183 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5184 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5185 Some instances of '#include <setjmp.h>' removed, if the
5186 only reason for the instance was because "lisp.h" was included.
5187 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5188 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5189 and _longjmp with the new symbols. Emacs already uses _setjmp if
5190 available, so this change affects only POSIXish hosts that have
5191 sigsetjmp but not _setjmp, such as some versions of Solaris and
5192 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5193 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5194 (png_load_body) [HAVE_PNG]:
5195 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5196 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5197 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5198 since PNG requires jmp_buf. This is the only exception to the
5199 general rule that we now use sys_setjmp and sys_longjmp.
5200 This exception is OK since this code does not change the signal
5201 mask or longjmp out of a signal handler.
5203 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5205 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5206 Include "syssignal.h", for 'main_thread'.
5208 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5210 Avoid out-of-range marker position (Bug#12426).
5211 * insdel.c (replace_range, replace_range_2):
5212 Adjust markers before overlays, as suggested by comments.
5213 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5214 Remove redundant check before calling offset_intervals.
5216 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5218 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5219 current buffer (Bug#12387).
5221 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5223 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5225 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5227 Use a more backwards-compatible timer format (Bug#12430).
5228 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5229 vector element, not from the 4th, since PSECS is now at the end.
5230 (Fcurrent_idle_time): Doc fix.
5232 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5234 Function to mark objects and remove killed buffers at once.
5235 * alloc.c (discard_killed_buffers): Rename to ...
5236 (mark_discard_killed buffers) ... new name. Add marking
5237 of remaining objects. Fix comment. Adjust users.
5238 (mark_object): Do not touch frame buffer lists here.
5239 * frame.c (delete_frame): Reset frame buffer lists here.
5241 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5243 Better workaround for GNOME bug when --enable-gcc-warnings.
5244 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5245 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5246 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5248 Simplify SIGIO usage (Bug#12408).
5249 The code that dealt with SIGIO was crufty and confusing, e.g., it
5250 played tricks like "#undef SIGIO" but these tricks were not used
5251 consistently. Simplify mostly by not #undeffing standard symbols,
5252 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5253 or not as we please) rather than "defined SIGIO" (standard symbol
5254 that we probably shouldn't #undef).
5255 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5256 Modules that need it can include it.
5257 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5258 * dispextern.h (ignore_sigio): New decl.
5259 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5260 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5261 * emacs.c (shut_down_emacs):
5262 * keyboard.c (kbd_buffer_store_event_hold):
5263 Use ignore_sigio rather than invoking 'signal' directly.
5264 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5266 (FIONREAD, SIGIO): Do not #undef.
5267 (tty_read_avail_input): Use #error rather than a syntax error.
5268 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5269 for I_PIPE, used by SETUP_SLAVE_PTY.
5270 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5271 * sysdep.c (croak): Remove; no longer needed. This bit of
5272 temporary code, with Fred N. Fish's comment that it's temporary,
5273 has been in Emacs since at least 1992!
5274 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5275 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5276 * syssignal.h (croak): Remove decl.
5277 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5278 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5279 now that we're termios-only.
5280 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5281 * term.c (dissociate_if_controlling_tty): Use #error rather than
5284 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5285 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5286 to work around GNOME bug 683906.
5287 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5288 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5289 This works around GCC bug 54561.
5291 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5293 More fixes for 'volatile' and setjmp/longjmp.
5294 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5295 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5296 (png_load_body) [HAVE_PNG]:
5297 (jpeg_load_body) [HAVE_JPEG]:
5298 New function, with most of the old parent function's body.
5299 (png_load) [HAVE_PNG]:
5300 (jpeg_load) [HAVE_JPEG]:
5301 Invoke the new function, to avoid longjmp munging our locals.
5302 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5303 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5304 longjmp is passed 2, as the C standard doesn't guarantee this.
5305 Instead, store the failure code into mgr->failure_code.
5307 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5309 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5310 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5311 (syms_of_keyboard): Remove support for unread-command-char.
5313 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5315 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5316 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5317 violation. (Bug#12426)
5319 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5321 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5323 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5325 * eval.c: Add `inhibit-debugger'.
5326 (Qinhibit_debugger): New symbol.
5327 (call_debugger): Bind it instead of Qdebug_on_error.
5328 (maybe_call_debugger): Test Vinhibit_debugger.
5329 (syms_of_eval): Define inhibit-debugger.
5330 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5331 (syms_of_xdisp): Remove inhibit-debug-on-message.
5333 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5335 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5336 If a nonvolatile local variable is written before a _longjmp to
5337 the frame containing the variable, and is read after the _longjmp,
5338 the value read is indeterminate. Some local variables of type
5339 'struct handler' and 'struct catchtag' are used in this way, so
5340 mark each of their slots as volatile if the slot can be set before
5341 _longjmp and read afterwards.
5342 * lisp.h (struct handler): var and chosen_clause are now volatile.
5343 (struct catchtag): val, next, and pdlcount are now volatile.
5345 * bidi.c (bidi_push_it, bidi_pop_it):
5346 * fns.c (copy_hash_table):
5347 * image.c (define_image_type):
5348 * keyboard.c (kbd_buffer_store_event_hold):
5349 * process.c (Fprocess_send_eof):
5350 * xfaces.c (x_create_gc) [HAVE_NS]:
5351 * xgselect.c (xg_select):
5352 Prefer assignment to memcpy when either will do.
5354 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5355 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5356 time an item is removed. No need to mark this function 'inline';
5357 the compiler knows better than we do.
5359 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5361 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5362 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5363 to change_frame_size (Bug#12388).
5364 (windowDidResize:): Pass YES to updateFrameSize.
5366 * nsterm.h: Add delay parameter to updateFrameSize.
5368 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5370 Discard killed buffers from deleted window and frame objects.
5371 This reduces an amount of references to killed buffers and
5372 helps GC to reclaim them faster.
5373 * alloc.c (discard_killed_buffers): New function.
5374 (mark_object): Use it for deleted windows and frames.
5375 (mark_object): If symbol's value is set up for a killed buffer
5376 or deleted frame, restore its global binding.
5377 * data.c (swap_in_global_binding): Add GC notice.
5378 (swap_in_symval_forwarding): Use convenient set_blv_where.
5379 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5380 * window.h: ... to here.
5382 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5384 Convenient macro to check whether the buffer is live.
5385 * buffer.h (BUFFER_LIVE_P): New macro.
5386 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5387 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5389 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5391 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5392 composition cases (Bug#12364).
5394 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5395 overhang of succeeding glyphs overlapping box cursor.
5397 * w32term.c (x_draw_glyph_string): Likewise.
5399 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5401 Simplify, document, and port floating-point (Bug#12381).
5402 The porting part of this patch fixes bugs on non-IEEE platforms
5403 with frexp, ldexp, logb.
5404 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5406 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5407 support, by removing commented-out code and briefly listing the
5408 C89 functions excluded. The commented-out stuff was confusing
5409 maintenance, e.g., we thought we needed cbrt but it was commented out.
5410 (logb): Remove decl; no longer needed.
5411 (isfinite): New macro, if not already supplied.
5412 (isnan): Don't replace any existing macro.
5413 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5414 are present on all C89 platforms.
5415 (Ffrexp): Do not special-case zero, as frexp does the right thing
5417 (Flogb): Do not use logb, as it doesn't have the desired meaning
5418 on hosts that use non-base-2 floating point. Instead, stick with
5419 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5420 frexp, to avoid getting an unspecified result.
5422 * xdisp.c (Qinhibit_debug_on_message): Now static.
5424 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5426 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5427 NSBezierPath (Bug#12131).
5429 2012-09-10 Chong Yidong <cyd@gnu.org>
5431 * fns.c (Fdelq, Fdelete): Doc fix.
5433 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5435 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5436 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5438 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5440 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5441 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5444 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5446 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5447 left fringe if the window has a left margin. This avoids leaving
5448 traces of the cursor because its leftmost pixel is not drawn over.
5450 * dispnew.c (update_window_line): When the left margin area of a
5451 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5452 that screen line. (Bug#12277)
5454 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5456 Assume C89 or later for math functions (Bug#12381).
5457 This simplifies the code, and makes it a bit smaller and faster,
5458 and (most important) makes it easier to clean up signal handling
5459 since we can stop worring about floating-point exceptions in
5460 library code. That was a problem before C89, but the problem
5461 went away many years ago on all practical Emacs targets.
5462 * data.c, image.c, lread.c, print.c:
5463 Don't include <math.h>; no longer needed.
5464 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5465 might be autoconfigured, as that never happens.
5467 * doprnt.c (DBL_MAX_10_EXP):
5468 * print.c (DBL_DIG):
5469 Remove. C89 or later always defines these.
5470 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5471 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5472 (arith_error, domain_error, domain_error2):
5473 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5474 no longer needed -- we simply return what C returns. All uses removed.
5475 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5477 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5478 Remove. All uses expanded, as these macros are no longer used
5479 more than once and are now more trouble than they're worth.
5480 (Ftan): Use tan, not sin / cos.
5481 (Flogb): Assume C89 frexp.
5482 (fmod_float): Assume C89 fmod.
5483 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5484 (init_floatfns): Remove. All uses removed.
5486 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5488 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5489 compositeToPoint for OSX < 10.6 (Bug#12390).
5491 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5493 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5494 This produces more-accurate results.
5496 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5498 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5499 changes (Bug#12088).
5501 2012-09-08 Chong Yidong <cyd@gnu.org>
5503 * syntax.c (Fstring_to_syntax): Doc fix.
5505 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5507 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5508 in the internal border.
5509 (x_set_window_size): Remove static variables and their usage.
5510 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5511 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5512 Remove fringe/internal border adjustment (Bug#11052).
5513 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5514 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5515 (ns_fix_rect_ibw): Remove.
5516 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5517 (ns_dumpglyphs_box_or_relief): Ditto.
5518 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5520 (ns_dumpglyphs_image): Ditto.
5521 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5523 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5524 their usage. Add fringe_extended_p and its use as in other terms.
5525 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5526 scroll bar was removed.
5527 (updateFrameSize): New function.
5528 (windowDidResize): Move code to updateFrameSize and call it.
5530 * nsterm.h (EmacsView): Add updateFrameSize.
5532 2012-09-07 Chong Yidong <cyd@gnu.org>
5534 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5536 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5538 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5540 More signal-handler cleanup (Bug#12327).
5541 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5542 Problem introduced when merging patches. Noted by Eli Zaretskii in
5543 <http://bugs.gnu.org/12327#67>.
5544 * floatfns.c: Comment fix.
5545 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5546 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5547 and anyway the declaration is harmless even if SIGDANGER is not defined.
5548 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5549 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5550 source files not surprisingly expected syssignal.h to define, or
5551 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5552 Include <sys/ioctl.h>, for FIONREAD.
5553 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5554 This eliminates a problem whereby other files mysteriously had
5555 to include "syssignal.h" before including "systty.h" if they
5556 wanted to use "#ifdef SIGIO".
5558 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5560 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5562 * w32.c (sigemptyset): Empty the set.
5563 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5565 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5567 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5569 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5570 (mark_object): Likewise for frame objects.
5572 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5574 * syssignal.h (handle_on_main_thread): Always declare,
5575 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5576 This ports to platforms without HAVE_PTHREAD.
5578 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5580 Signal-handler cleanup (Bug#12327).
5581 Emacs's signal handlers were written in the old 4.2BSD style with
5582 sigblock and sigmask and so forth, and this led to some
5583 inefficiencies and confusion. Rewrite these to use
5584 pthread_sigmask etc. without copying signal sets around. Also,
5585 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5586 'signal', and instead use functions that do not attempt to take
5587 over the system name space. This patch causes Emacs's text
5588 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5589 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5590 Do not include <signal.h> or "syssignal.h", as these
5591 modules do not use signals.
5592 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5593 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5594 Do not include <signal.h>, as "syssignal.h" does that for us now.
5595 * atimer.c (sigmask_atimers): New function.
5596 (block_atimers, unblock_atimers): New functions,
5597 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5599 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5600 no longer needed here.
5601 * emacs.c (main): Inspect existing signal handler with sigaction,
5602 so that there's no need to block and unblock SIGHUP.
5603 * sysdep.c (struct save_signal): New member 'action', replacing
5604 old member 'handler'.
5605 (save_signal_handlers, restore_signal_handlers):
5606 Use sigaction instead of 'signal' to save and restore.
5607 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5608 New function. All users of 'signal' modified to use set_sighandler
5609 if they're writeonly, and to use sys_signal if they're read+write.
5610 (emacs_sigaction_init, forwarded_signal): New functions.
5611 (sys_signal): Remove. All uses replaced by calls to sigaction
5612 and emacs_sigaction_init, or by direct calls to 'signal'.
5613 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5614 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5615 all uses replaced by pthread_sigmask etc. calls.
5616 * syssignal.h: Include <signal.h>.
5617 (emacs_sigaction_init, forwarded_signal): New decls.
5618 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5619 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5620 (sigmask, sys_sigmask): Remove; no longer needed.
5621 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5622 (sigblock, sigunblock, sigfree):
5623 (sigsetmask) [!defined sigsetmask]:
5624 Remove. All uses replaced by pthread_sigmask.
5625 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5626 no longer need to be replaced, and its typical old uses
5627 are now done via emacs_sigaction_init and sigaction.
5628 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5629 (sys_sigdel): Remove; unused.
5630 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5632 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5634 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5635 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5637 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5639 Explicitly mark buffer_defaults and buffer_local_symbols.
5640 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5641 mark_local_symbols here.
5642 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5643 since special buffers aren't marked here any more.
5644 (allocate_buffer): Chain new buffer with all_buffers here...
5645 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5647 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5648 (syms_of_buffer): Remove staticpro of the above.
5649 (init_buffer_once): Set names for buffer_defaults and
5650 buffer_local_symbols.
5652 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5654 Use bool for booleans in font-related modules.
5655 * font.c (font_intern_prop, font_style_to_value)
5656 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5657 (generate_otf_features, font_check_otf_features, font_check_otf)
5658 (font_match_p, font_list_entities, font_at):
5659 * fontset.c (fontset_id_valid_p, reorder_font_vector
5660 (fontset_find_font, Fset_fontset_font)
5661 (face_suitable_for_char_p) [0]:
5662 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5663 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5664 (m17n_flt_initialized, ftfont_shape_by_flt):
5665 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5666 * nsfont.m (nsfont_draw):
5667 * w32font.c (w32font_draw):
5668 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5669 Use bool for booleans.
5670 * font.h: Adjust to above API changes.
5671 (struct font, struct font_driver, struct font_driver_list):
5672 Use bool for booleans.
5673 (struct font): Remove useless member encoding_type.
5675 * fontset.c, xftfont.c: Omit unnecessary static decls.
5677 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5679 * alloc.c (mark_object): Revert window marking code
5680 since it's unsafe for the Fset_window_configuration.
5682 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5684 Fix race conditions with signal handlers and errno (Bug#12327).
5685 Be more systematic about preserving errno whenever a signal
5686 handler returns, even if it's not in the main thread. Do this by
5687 renaming signal handlers to distinguish between signal delivery
5688 and signal handling. All uses changed.
5689 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5690 * data.c (deliver_arith_signal): Rename from arith_error.
5691 * dispnew.c (deliver_window_change_signal): Rename from
5692 window_change_signal.
5693 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5694 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5695 * keyboard.c (deliver_input_available_signal): Rename from
5696 input_available_signal.
5697 (deliver_user_signal): Rename from handle_user_signal.
5698 (deliver_interrupt_signal): Rename from interrupt_signal.
5699 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5700 (deliver_child_signal): Rename from sigchld_handler.
5701 * atimer.c (handle_alarm_signal):
5702 * data.c (handle_arith_signal):
5703 * dispnew.c (handle_window_change_signal):
5704 * emacs.c (handle_fatal_signal, handle_danger_signal):
5705 * keyboard.c (handle_input_available_signal):
5706 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5707 * process.c (handle_pipe_signal, handle_child_signal):
5708 New functions, with the actual signal-handling code taken from the
5709 original respective signal handlers, sans the sporadic attempts to
5710 preserve errno, since that's now done by handle_on_main_thread.
5711 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5712 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5713 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5715 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5716 Move initialization of main_thread to sysdep.c's init_signals.
5717 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5718 our usage, and simplifies the mainline code.
5719 (record_child_status_change): New static function, as a helper
5720 for handle_child_signal, and with most of the old child handler's
5722 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5723 (handle_child_signal): Use the above.
5724 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5725 Moved here from emacs.c.
5726 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5727 code moved here from emacs.c's main function.
5728 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5729 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5730 This lets callers save and restore errno properly.
5732 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5734 Remove redundant or unused things here and there.
5735 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5736 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5737 * editfns.c (Fcompare_buffer_substrings): Likewise.
5738 * frame.h (struct terminal, struct font_driver_list):
5739 Remove redundant declarations.
5740 * window.h (Qleft, Qright): Likewise.
5742 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5744 Do not mark objects from deleted buffers, windows and frames.
5745 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5746 (mark_object): Likewise for windows and frames.
5748 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5750 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5751 buffer_defaults and buffer_local_symbols as valid objects.
5752 Return special value to denote them.
5754 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5756 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5757 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5758 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5759 (file_name_absolute_p, Fsubstitute_in_file_name):
5760 (check_executable, check_writable, Ffile_accessible_directory_p)
5761 (Fset_file_selinux_context, Fdefault_file_modes)
5762 (Finsert_file_contents, choose_write_coding_system)
5763 (Fwrite_region, build_annotations, a_write, e_write)
5765 * filelock.c (boot_time_initialized, get_boot_time)
5766 (get_boot_time_1, lock_file_1, within_one_second):
5767 * floatfns.c (in_float):
5768 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5769 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5770 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5771 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5772 * window.c (compare_window_configurations):
5773 Use bool for booleans.
5774 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5775 (Fdefault_file_modes): Now mode_t, not int, for modes.
5776 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5777 (internal_delete_file): Now returns void, not a (boolean) int,
5778 since nobody was looking at the return value.
5779 * lisp.h, window.h: Adjust to above API changes.
5781 * xdisp.c (set_message): Simplify and reindent last change.
5783 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5785 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5787 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5789 * eval.c (call_debugger): Make the function non-static so that we
5790 can call it from set_message.
5792 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5793 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5795 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5797 Give more-useful info on a fatal error (Bug#12328).
5798 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5799 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5800 of doing the work ourselves.
5801 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5802 do most of the work.
5803 (fatal_error_backtrace): New function, taken from the guts
5804 of the old fatal_error_signal, but with a new option to output
5806 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5807 info about the signal than just its number.
5808 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5809 * sysdep.c: Include <execinfo.h>
5810 (emacs_backtrace): New function, taken partly from the previous
5811 code of the 'die' function.
5812 (emacs_abort): Call fatal_error_backtrace rather than abort.
5814 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5816 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5817 eager (load-time) macro-expansion.
5818 * lisp.mk (lisp): Add macroexp.
5820 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5822 Simplify redefinition of 'abort' (Bug#12316).
5823 Do not try to redefine the 'abort' function. Instead, redo
5824 the code so that it calls 'emacs_abort' rather than 'abort'.
5825 This removes the need for the NO_ABORT configure-time macro
5826 and makes it easier to change the abort code to do a backtrace.
5827 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5828 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5829 Remove; sysdep.c's emacs_abort now takes its place.
5830 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5831 'abort' changed to use 'emacs_abort'.
5832 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5833 (abort) [!defined abort]: Rename to ...
5834 (emacs_abort): ... new name.
5835 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5836 the place of the old 'abort' in emacs.c.
5837 * w32.c, w32fns.c (abort): Do not #undef.
5838 * w32.c (emacs_abort): Rename from w32_abort.
5840 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5842 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5843 offsets[j].dv, since the y axis of the screen coordinates points
5844 down, while the y axis of the font definition coordinates points
5845 up. This fixes display of Arabic diacritics such as KASRA and
5846 KASRATAN. (Bug#11860)
5848 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5850 Be more systematic about _setjmp vs setjmp.
5851 * alloc.c (test_setjmp, mark_stack):
5852 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5853 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5854 (png_load, my_error_exit, jpeg_load):
5855 * process.c (send_process_trap, send_process):
5856 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5857 The underscored versions are up to 30x faster on some hosts.
5858 Formerly, the code used setjmp+longjmp sometimes and
5859 _setjmp+_longjmp at other times, with no particular reason to
5860 prefer setjmp+longjmp.
5862 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5864 Fix minor problem found by static checking.
5865 * buffer.c (Fdelete_all_overlays): Return nil.
5867 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5869 * buffer.c (Fdelete_all_overlays): New function.
5871 2012-09-03 Chong Yidong <cyd@gnu.org>
5873 * gtkutil.c: Add extern decl for Qxft.
5875 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5877 * emacs.c, eval.c: Use bool for boolean.
5878 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5879 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5880 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5881 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5882 (main, decode_env_path, Fdaemon_initialized):
5883 * eval.c (call_debugger, Finteractive_p, interactive_p):
5884 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5885 (maybe_call_debugger, Fbacktrace):
5886 * process.c (read_process_output, exec_sentinel):
5887 Use bool for booleans.
5888 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5889 All callers changed.
5890 * eval.c (interactive_p): Omit always-true boolean argument
5891 EXCLUDE_SUBRS_P. All callers changed.
5892 * dispextern.h, lisp.h: Reflect above API changes.
5893 * firstfile.c (dummy): Use the address of 'main', whose signature
5894 won't change, instead of the address of 'initialize', whose
5895 signature just changed from int to bool.
5896 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5897 * msdos.c (fatal_error_in_progress): ... from here.
5898 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5900 (redisplay_internal, unwind_redisplay): Simply clear
5901 REDISPLAYING_P when unwinding, instead of saving its previous,
5902 always-false value and then restoring it.
5904 Clean up some extern decls.
5905 Mostly, this hoists extern decls out of .c files and into .h files.
5906 That way, we're more likely to catch errors if the interfaces change.
5907 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5908 declare xg_mark_data.
5909 * dispextern.h (x_frame_parm_handlers):
5911 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5912 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5913 (Qultra_bold, Qoblique, Qitalic):
5914 Move extern decl here from .c file.
5915 * alloc.c (xg_mark_data) [USE_GTK]:
5917 * eval.c (Qlexical_binding):
5918 * fns.c (time) [!HAVE_UNISTD_H]:
5919 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
5920 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
5921 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
5922 * lread.c (Qinternal_interpreter_environment):
5923 * minibuf.c (Qbuffer):
5924 * process.c (QCfamily, QCfilter):
5925 * widget.c (free_frame_faces):
5926 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5927 * xfont.c (x_clear_errors):
5928 * xterm.c (x_frame_parm_handlers):
5929 Remove now-redundant extern decls.
5930 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5931 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5933 * xfaces.c: Remove unnecessary static decls.
5934 * xterm.c (updating_frame): Remove decl of nonexistent object.
5936 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)

5994 offset adjustment values separately for each cluster. (Bug#11860)
5996 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5997 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5998 about implicit conversions from integer to pointer.

6056 window system declarations.
6058 * frame.h: Move common functions here: set_frame_menubar,
6059 x_set_window_size, x_sync, x_get_focus_frame,
6060 x_set_mouse_position, x_set_mouse_pixel_position,
6061 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6118 for GCC 4.7.1 x86-64.
6120 2012-08-30 Glenn Morris <rgm@gnu.org>
6122 * lread.c (init_lread): For out-of-tree builds, only add the
6123 source directory's site-lisp dir to the load-path if it exists,
6124 consistent with in-tree builds. (Bug#12302)
6126 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6359 * lisp.h (ASET): Remove attempt to detect side effects.
6360 It was meant to be temporary and it often doesn't work,
6361 because when IDX has side effects the behavior of IDX==IDX
6362 is undefined. See Stefan Monnier in
6363 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6365 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6374 as that's faster and simpler than static storage. Don't bother
6375 with the g_main_context_query overhead if g_main_context_pending
6376 says no events are pending.
6377 (gfds, gfds_size): Remove these static vars.

6379 All uses and decls removed.

6386 * casetab.c (set_case_table):
6387 * category.c, category.h (word_boundary_p):
6388 * category.h (CHAR_HAS_CATEGORY):
6389 Use bool for booleans, instead of int.
6391 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6393 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6395 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6397 On assertion failure, print backtrace if available.
6398 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6399 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6400 * Makefile.in (LIB_EXECINFO): New macro.
6403 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6404 * bytecode.c (exec_byte_code):
6405 * callint.c (check_mark, Fcall_interactively):
6406 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6407 (getenv_internal, sync_process_alive, call_process_exited):
6408 * lisp.h (USE_SAFE_ALLOCA):
6409 Use bool for booleans, instead of int.
6410 * lisp.h, process.h: Adjust prototypes to match above changes.
6411 * callint.c (Fcall_interactively): Don't assume the mark's
6412 offset fits in 'int'.
6414 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6416 * buffer.c, buffer.h: Use bool for boolean.
6417 * buffer.c (reset_buffer_local_variables)
6418 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6419 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6420 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6421 (overlay_touches_p, overlay_strings, Foverlay_put)
6422 (report_overlay_modification, call_overlay_mod_hooks):
6423 (mmap_enlarge, mmap_set_vars):
6424 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6425 Use bool for booleans, instead of int.
6426 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6427 since the 1-or-0 return value is always ignored anyway.
6428 (mmap_initialized_p):
6429 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6430 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6432 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6434 * bidi.c: Use bool for boolean.
6435 This is a bit more readable, and makes the text segment of bidi.o
6436 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6437 Presumably it's faster too.
6438 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6440 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6441 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6442 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6443 (bidi_explicit_dir_char, bidi_level_of_next_char)
6444 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6445 Use bool for booleans, instead of int.
6446 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6447 (bidi_unshelve_cache): Adjust decls to match code.
6449 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6451 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6454 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6456 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6457 * atimer.h: Include <stdbool.h>.
6459 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6461 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6462 compile time tests instead of run time tests on systems that do
6464 (FRAME_MAC_P): Remove leftover from deleted code.
6465 * frame.c (syms_of_frame): Remove leftover from deleted code.
6467 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6471 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6473 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6474 Otherwise, the compiler complains about (A?B:C) where B is void
6475 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6476 (fontset_add): Return void, for FONTSET_ADD.
6478 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6480 * alloc.c: Use bool for booleans.
6481 (gc_in_progress, abort_on_gc)
6482 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6483 (dont_register_blocks) [GC_MALLOC_CHECK]:
6484 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6485 (check_string_bytes, make_specified_string, memory_full)
6486 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6487 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6488 (mark_stack, valid_pointer_p, make_pure_string)
6489 (Fgarbage_collect, survives_gc_p, gc_sweep):
6490 Use bool for booleans, instead of int.
6491 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6492 Remove unused local.
6493 * alloc.c (PURE_POINTER_P):
6494 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6495 * editfns.c (Fformat):
6496 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6498 * fns.c (sweep_weak_table):
6499 * lisp.h (suppress_checking, push_message, survives_gc_p)
6500 (make_pure_string, gc_in_progress, abort_on_gc):
6501 * lread.c (readchar, read1):
6502 * print.c (Fprin1_to_string):
6503 * xdisp.c (push_message):
6504 Use bool for booleans affected directly or indirectly by
6507 Make recently-introduced setters macros.
6508 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6509 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6510 (set_fontset_default, set_fontset_fallback): Rename from their
6511 upper-case counterparts, and make them functions rather than macros.
6512 This is more consistent with the other recently-introduced setters.
6513 These don't need to be inline, since they're local.
6515 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6517 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6518 the loop (Bug#12247).
6520 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6522 * lisp.h (vcopy): Use memcpy rather than our own loop.
6523 This fixes a performance regression introduced by the recent
6524 addition of vcopy. This means 'vcopy' will need to be modified
6525 for a copying collector, but that's OK. Also, tighten the
6526 checking in the assertion.
6528 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6530 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6531 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6532 non-base glyph for the width of the base character, according to
6533 what x_draw_composite_glyph_string_foreground expects.
6534 Generate WADJUST value according to composition_gstring_width's
6535 expectations, to produce correct width of the composed character.
6536 Reverse the sign of the DU offset produced by ScriptPlace.
6538 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6540 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6542 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6544 Avoid direct writes to contents member of struct Lisp_Vector.
6545 * lisp.h (vcopy): New function to copy data into vector.
6546 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6547 * fns.c (Ffillarray): Use ASET.
6548 * keyboard.c (timer_check_2): Use AREF and ASET.
6549 (append_tool_bar_item, Frecent_keys): Use vcopy.
6550 * lread.c (read_vector): Use ASET.
6551 * msdos.c (Frecent_doskeys): Use vcopy.
6552 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6553 (Finternal_merge_in_global_face): Use ASET and vcopy.

6559 the position of its buffer's point.
6560 (Fset_window_point): For the selected window always go in its
6561 buffer to the specified position.
6563 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6565 Setter macros for fontsets.
6566 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6567 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6568 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6571 2012-08-20 Glenn Morris <rgm@gnu.org>
6573 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6574 Don't assume that `ln -f' works.
6576 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6578 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6579 and later about non-assignments with no effect. See discussion at
6580 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6583 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6585 Inline setter functions for Lisp_Objects slots of struct specbinding.
6586 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6589 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6591 * window.c (select_window): Always make selected window's buffer
6594 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6596 Use AREF and ASET for docstrings of category tables.
6597 * category.h (CATEGORY_DOCSTRING): Use AREF.
6598 (SET_CATEGORY_DOCSTRING): Use ASET.
6599 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6601 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6603 Inline setter functions for hash table members.
6604 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6605 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6606 (set_hash_key_and_value, set_hash_index, set_hash_next)
6607 (set_hash_hash): New functions.
6608 * charset.c, fns.c: Adjust users.
6610 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6612 Inline getter and setter functions for per-buffer values.
6613 * buffer.h (per_buffer_default, set_per_buffer_default)
6614 (per_buffer_value, set_per_buffer_value): New functions.
6615 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6616 * buffer.c, data.c: Adjust users.
6618 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6620 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6622 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6624 Rely on <config.h> + <unistd.h> to declare 'environ',
6625 as gnulib does this if the system doesn't.
6626 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6627 Remove declaration. MS-Windows declares it on stdlib.h which is
6628 included by conf_post.h.
6629 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6630 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6631 * vm-limit.c: Include <unistd.h>, for 'environ'.
6633 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6634 (start_of_data): Remove decl; mem-limits.h provides it.
6636 * xdisp.c (handle_invisible_prop): Make it a bit faster
6637 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6639 2012-08-19 Chong Yidong <cyd@gnu.org>
6641 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6644 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6646 * .gdbinit: Use call instead of set when calling a function in the
6649 * data.c (set_internal): Don't use set_blv_found.
6650 (Fkill_local_variable): Likewise.
6652 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6654 * nsfont.m (ns_ascii_average_width): Ensure the string
6655 ascii_printable is initialized with a null-terminated character
6656 array. Otherwise, it can contain undesired extra characters.
6658 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6660 port new setting code to Sun C 5.8 2005/10/13
6661 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6662 Return void, not Lisp_Object. Otherwise, the compiler
6663 complains about (A?B:C) where B is void and C is Lisp_Object
6664 when compiling CHAR_TABLE_SET, due to the recent change to
6665 the API of sub_char_table_set_contents.
6667 2012-08-18 Chong Yidong <cyd@gnu.org>
6669 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6670 for the string case (Bug#3874).
6672 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6674 * buffer.h (BSET): Remove (Bug#12215).

7498 * w32.c (init_environment): Change the default values of many
7499 environment variables in dflt_envvars[] to NULL, to avoid pushing
7500 them into environment when they were not already defined.
7501 Remove the code that deletes site-lisp subdirectories from the default
7502 value of EMACSLOADPATH, as it is no longer needed.
7503 (check_windows_init_file): Now external, not static.
7504 Use Vload_path as is, without adding anything, as this function is now
7505 called when Vload_path is already set up.
7507 * w32.h (check_windows_init_file): Add prototype.
7509 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7553 Remove unnecessary pointer casts.
7554 * alloc.c (record_xmalloc): New function.
7555 * lisp.h (record_xmalloc): New decl.
7556 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7557 more like a function. This is because the pointer cast is not
7558 needed. All uses changed.
7559 * print.c (print_string, print_error_message): Avoid length recalc.
7561 Improve fix for macroexp crash with debugging (Bug#12118).
7562 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7563 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7564 not supposed to be invoked from the garbage collector.

7566 (gc_aset): New function, which is like ASET but can be
7567 used in the garbage collector.

7596 with addition of handling of symlinks and support for 'lstat'.
7597 If possible, get file's attributes and security information by
7598 handle, not by name. Produce S_IFLNK bit for symlinks, when
7599 called from 'lstat'.
7600 (stat, lstat): New functions, call 'stat_worker'.
7601 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7602 symlinks when the underlying filesystem supports them.
7604 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7606 Fix macroexp crash on Windows with debugging (Bug#12118).
7607 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7608 checking subscripts; problem introduced with the recent
7609 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7610 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7611 since it's used in non-static inline functions now.
7613 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7614 Don't assume buffer size fits in 'int'. Remove unused local.

7634 * composite.c (COMPOSITE_INLINE):
7635 * dispnew.c (DISPEXTERN_INLINE):
7636 * sysdep.c (SYSTIME_INLINE):
7637 Define to EXTERN_INLINE, so that the corresponding functions
7638 are compiled into code.

7640 (INLINE_HEADER_END): New macros.
7641 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7661 hard-coding the path separator.
7663 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7665 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7666 This how ASET and AREF are supposed to work, and makes
7667 it easier to think about future improvements. See
7668 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7669 * charset.h (set_charset_attr): New function.

8158 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8159 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8160 emacs.c, as this is a more-suitable home. Had this been done earlier
8161 the fix for 12036 would have avoided some of the problems noted in
8162 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8163 would have been more obvious.
8164 * emacs.c: Do not include <verify.h>; no longer needed.
8165 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8166 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8167 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8168 Remove; now done in lisp.h.
8169 * lisp.h (PUBLISH_TO_GDB): New macro.
8170 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8171 (DATA_SEG_BITS): Use it.
8172 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8173 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8174 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8175 not be usable in #if. This simplifies things.
8177 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8179 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8181 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

8184 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8185 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8186 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8187 Adjust to changes in lisp.h and emacs.c, by using
8188 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8189 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8190 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8191 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8192 instead of gdb_valbits.
8193 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8194 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8195 instead of gdb_array_mark_flag.
8196 (xboolvector): Get size from $->size, not $->header.size.
8197 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8198 (xreload, hook-run, hookpost-run): Remove.
8199 * emacs.c: Include <verify.h>.
8200 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8201 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8203 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8204 (gdb_USE_LSB_TAG): New enum constants.
8205 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8206 Also define these as enum constants, so they're visible to GDB.
8207 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8208 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8209 as constants, so they're visible to GDB.

8211 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8212 Now enum constants, not macros, so they're visible to GDB.
8213 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8214 more convenient now. All uses changed.
8215 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8216 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8218 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8225 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8226 add argument, tune behavior, and adjust all callers.
8228 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8230 Use typedef for EMACS_INT, EMACS_UINT.
8231 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8232 than macros. This simplifies debugging in the usual case, since
8233 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8234 and it allows expressions involving EMACS_INT casts.
8235 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8237 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8247 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8249 Adjust buffer text indirection counters at the end of Fkill_buffer.
8250 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8251 buffer is definitely dead. This should really fix an issue reported
8252 by Christoph Scholtes again. (Bug#12007).
8253 (init_buffer_once): Initialize indirection counters of
8254 buffer_defaults and buffer_local_symbols (for sanity and safety).
8256 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8258 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8259 and continuation glyphs on tooltip frames, leave them at zero.

8287 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8289 Swap buffer text indirection counters in Fbuffer_swap_text.
8290 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8291 This avoids crash reported by Christoph Scholtes at
8292 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8294 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8296 * nsmenu.m (Popdown_data): New struct.

8319 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8321 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8322 as it's limited by the amount of memory, not by INT_MAX.
8324 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8326 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8327 in special-event-map. See the discussion at

8477 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8479 * eval.c (Fdefvar): Don't check constants since we only set the var if
8480 it's not yet defined anyway (bug#11904).
8482 * lisp.h (last_undo_boundary): Declare new var.
8483 * keyboard.c (command_loop_1): Set it.
8484 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8485 were auto-added by the command loop (bug#11774).

9050 * s/aix4-2.h (unix): Remove; no longer needed.
9052 EMACS_TIME simplification (Bug#11875).
9053 This replaces macros (which typically do not work in GDB)
9054 with functions, typedefs and enums, making the code easier to debug.
9055 The functional style also makes code easier to read and maintain.
9056 * systime.h: Include <sys/time.h> on all hosts, not just if
9057 WINDOWSNT, since 'struct timeval' is needed in general.
9058 (EMACS_TIME): Now a typedef, not a macro.
9059 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9061 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
9062 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
9063 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9064 (EMACS_TIME_LE): Now functions, not macros.
9065 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9066 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9067 which are not functions. All uses rewritten to use:
9068 (make_emacs_time): New function.
9069 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9070 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9071 not functions. All uses rewritten to use the following, respectively:
9072 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9073 (add_emacs_time, sub_emacs_time): New functions.
9074 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9075 * fileio.c (Fcopy_file):
9076 * xterm.c (XTflash): Get the current time closer to when it's used.
9077 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
9079 * bytecode.c (targets): Suppress -Woverride-init warnings.
9081 Simplify by avoiding confusing use of strncpy etc.
9082 * doc.c (Fsnarf_documentation):
9083 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
9084 * frame.c (Fmake_terminal_frame):
9085 * gtkutil.c (get_utf8_string):
9087 * nsmenu.m (ns_update_menubar):
9088 * regex.c (regerror):
9089 Prefer memcpy to strncpy and strncat when either will do.
9090 * fileio.c (Fsubstitute_in_file_name):
9091 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9092 (menu_separator_name_p):
9093 * nsmenu.m (ns_update_menubar):
9094 Prefer memcmp to strncmp when either will do.
9095 * nsterm.m: Include <ftoastr.h>.
9097 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9098 Prefer snprintf to strncpy.
9099 * nsterm.m (ns_term_init):
9100 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9101 * nsterm.m (ns_term_init):
9102 Avoid the need for strncpy, by using build_string or
9103 make_unibyte_string directly. Use dtoastr, not snprintf.
9104 * process.c (Fmake_network_process): Diagnose service names that
9105 are too long, rather than silently truncating them or creating
9106 non-null-terminated names.
9107 (Fnetwork_interface_info): Likewise, for interface names.
9108 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9109 Prefer sprintf to strncat.
9110 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9111 Prefer vsnprintf to vsprintf + strncpy.
9113 2012-07-10 Glenn Morris <rgm@gnu.org>
9115 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9116 Clarify fallback case.
9118 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9120 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9121 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9122 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9123 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9124 where argument type is known to be a Lisp_Cons.
9126 2012-07-10 Tom Tromey <tromey@redhat.com>
9128 * bytecode.c (BYTE_CODE_THREADED): New macro.
9129 (BYTE_CODES): New macro. Replaces all old byte-code defines.
9130 (enum byte_code_op): New type.
9131 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
9132 (exec_byte_code): Use them. Use token threading when applicable.
9134 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9136 Optimize pure C strings initialization.
9137 * lisp.h (make_pure_string): Fix prototype.
9138 (build_pure_c_string): New function, defined as static inline. This
9139 provides a better opportunity to optimize away calls to strlen when
9140 the function is called with compile-time constant argument.
9141 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9142 argument, adjust users accordingly. Use build_pure_c_string where
9144 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9145 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9146 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9148 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9150 Avoid calls to strlen in miscellaneous functions.
9151 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9152 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9153 * lread.c (openp): Likewise.
9155 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9157 Avoid calls to strlen in path processing functions.
9158 * fileio.c (file_name_as_directory): Add comment. Change to add
9159 srclen argument and return the length of result. Adjust users
9161 (directory_file_name): Fix comment. Change to add srclen argument,
9162 swap 1st and 2nd arguments to obey the common convention.
9163 Adjust users accordingly.
9164 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9166 2012-07-10 Glenn Morris <rgm@gnu.org>
9168 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9169 Move PENDING_OUTPUT_COUNT definition to configure.
9171 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9172 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9173 * s/gnu.h (DATA_START): Move definitions to configure.
9175 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9176 We include usg5-4-common.h, which defines them both.
9178 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9179 O_RDONLY already includes it).
9181 Stop ns builds setting the EMACSLOADPATH environment variable.
9182 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9183 Now it does not set EMACSLOADPATH, just returns the load-path string.
9184 * nsterm.h: Update accordingly.
9185 * lread.c [HAVE_NS]: Include nsterm.h.
9186 (init_lread) [HAVE_NS]: Use ns_load_path.
9187 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9189 2012-07-09 Glenn Morris <rgm@gnu.org>
9191 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9192 since the included bsd-common.h does so.
9194 Stop ns builds setting the EMACSPATH environment variable.
9195 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9196 (ns_init_paths): Do not set EMACSPATH.
9197 * nsterm.h (ns_exec_path): Add it.
9198 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9201 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9203 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9205 * process.c (wait_reading_process_output): 'waitchannels' was unset
9206 when read_kbd || !NILP (wait_for_cell); fix this.
9208 Add GCC-style 'const' attribute to functions that can use it.
9209 * character.h (char_resolve_modifier_mask):
9210 * keyboard.h (make_ctrl_char):
9211 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9212 (init_character_once, next_almost_prime, init_fns, init_image)
9213 (flush_pending_output, init_sound):
9214 * mem-limits.h (start_of_data):
9215 * menu.h (finish_menu_items):
9216 Add ATTRIBUTE_CONST.
9217 * emacs.c (DEFINE_DUMMY_FUNCTION):
9218 Declare the dummy function with ATTRIBUTE_CONST.
9219 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9220 Add decls with ATTRIBUTE_CONST.
9222 Minor improvements to make_formatted_string.
9223 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9224 where int is good enough, as vsprintf returns an int.
9225 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9227 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9229 Use make_formatted_string to avoid double length calculation.
9230 * lisp.h (make_formatted_string): New prototype.
9231 * alloc.c (make_formatted_string): New function.
9232 * buffer.c (Fgenerate_new_buffer_name): Use it.
9233 * dbusbind.c (syms_of_dbusbind): Likewise.
9234 * editfns.c (Fcurrent_time_zone): Likewise.
9235 * filelock.c (get_boot_time): Likewise.
9236 * frame.c (make_terminal_frame, set_term_frame_name)
9237 (x_report_frame_params): Likewise.
9238 * image.c (gs_load): Likewise.
9239 * minibuf.c (get_minibuffer): Likewise.
9240 * msdos.c (dos_set_window_size): Likewise.
9241 * process.c (make_process): Likewise.
9242 * xdisp.c (ensure_echo_area_buffers): Likewise.
9243 * xsettings.c (apply_xft_settings): Likewise.
9245 2012-07-09 Glenn Morris <rgm@gnu.org>
9247 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
9248 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
9249 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
9250 * nsterm.h (ns_etc_directory): Add it.
9251 * callproc.c [HAVE_NS]: Include nsterm.h.
9252 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
9254 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9256 Move marker debugging code under MARKER_DEBUG.
9257 * marker.c (MARKER_DEBUG): Move marker debugging code under
9258 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9259 for bootstrap with --enable-checking (~3x slowdown reported
9260 by Juanma Barranquero <lekktu@gmail.com>).
9261 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9263 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9265 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9266 See <http://bugs.gnu.org/11825#29>.
9268 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9270 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9271 has no font, use the frame's font. (Bug#11813)
9272 (display_line): Add commentary about displaying truncation glyphs
9274 (produce_special_glyphs): Move here from term.c.
9276 * term.c (produce_special_glyphs): Move to xdisp.c.
9278 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9281 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9283 * xdisp.c (display_line): Avoid warning about implicit declaration
9286 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9288 * lisp.h: Remove empty conditional.
9290 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9292 * lread.c (load_path_check): Now static.
9294 Fix some minor --with-ns problems found by static checking.
9295 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9296 (x_set_font) [!HAVE_X_WINDOWS]:
9297 * image.c (xpm_load_image) [HAVE_NS]:
9298 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9299 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9300 Remove unused local.
9301 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9302 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9303 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9304 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9305 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9306 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9307 Fix pointer signedness problem.
9308 * xfaces.c (FRAME_X_FONT_TABLE):
9309 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9311 2012-07-07 Glenn Morris <rgm@gnu.org>
9313 * lread.c (load_path_check): New function, split from init_lread.
9314 (init_lread): Reorganize. Motivation:
9315 If EMACSLOADPATH is set, check/warn about that rather than the
9316 defaults, which we are not going to use. Hence we can remove
9317 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9318 Don't warn if site-lisp directories are missing.
9319 If not installed, start from a blank load-path, since
9320 PATH_LOADSEARCH refers to the eventual installation directories.
9322 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9324 Support truncation and continuation glyphs on GUI frames, when
9325 fringes are disabled. (Bug#11832)
9326 * xdisp.c (init_iterator): Get dimensions of truncation and
9327 continuation glyphs even if on GUI frames.
9328 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9329 or both, are absent.
9330 (start_display, move_it_in_display_line_to): Handle the case of a
9331 GUI frame without a fringe to display continuation or truncation
9333 (insert_left_trunc_glyphs): Support GUI frames: make sure
9334 truncation glyphs overwrite enough glyphs from the current line to
9335 have sufficient space in pixels.
9336 (display_line): Support truncation and continuation glyphs on GUI
9337 frames. If some spare pixels are left on the line after inserting
9338 the truncation glyphs, fill that space with a stretch glyph of a
9339 suitably computed width.
9341 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9342 produce_glyphs, to support GUI sessions.
9344 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9346 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9348 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9350 Do not require float-time's arg to fit in time_t (Bug#11825).
9351 This works better on hosts where time_t is unsigned, and where
9352 float-time is applied to the (negative) difference between two times.
9353 * editfns.c (decode_time_components): Last arg is now double *,
9354 not int *, and means to store all the result as a double, without
9355 worrying about whether the seconds part fits in time_t.
9356 All callers changed.
9357 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9358 All callers changed.
9359 (Ffloat_time): Do not fail merely because the specified time falls
9360 outside of time_t range.
9362 2012-07-07 Glenn Morris <rgm@gnu.org>
9364 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9365 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9366 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9368 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9370 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9371 Update dependencies.
9373 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9375 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9377 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9378 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9379 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9380 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9381 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9382 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9384 * xfont.c (compare_font_names): Redo to omit the need for casts.
9386 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9388 * xfns.c (Fx_change_window_property): Doc fix.
9389 * w32fns.c (Fx_change_window_property): Doc fix.
9391 * w32fns.c (Fx_window_property): Accept the same arguments as the
9392 X Windows version. Doc fix.
9393 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9395 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9396 Eli Zaretskii <eliz@gnu.org>
9398 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9399 Windows-specific code from nt/config.nt moved here.
9400 Obsolete settings removed.
9402 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9404 * process.c: Avoid unnecessary calls to gettime.
9405 (wait_reading_process_output): Don't get the time of day
9406 when gobbling data immediately and not waiting, as there's no need
9407 for it in that case. This removes a FIXME.
9409 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9411 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9412 is defined (Bug#11768).
9414 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9416 Fix marker debugging code.
9417 * marker.c (byte_char_debug_check): Do not perform the check
9418 if buffer is not multibyte.
9419 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9420 Call byte_char_debug_check with correct arguments.
9422 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9424 Compile marker debugging code only if ENABLE_CHECKING is defined.
9425 * marker.c (byte_char_debug_check, count_markers):
9426 Use only if ENABLE_CHECKING is defined.
9427 (byte_debug_flag): Remove.
9428 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9429 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9431 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9433 Avoid code repetition in marker-related functions.
9434 * marker.c (attach_marker): New function.
9435 (Fset_marker, set_marker_restricted, set_marker_both)
9436 (set_marker_restricted_both): Use it.
9437 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9438 Consistently rename charno to charpos.
9439 (marker_position): Add eassert.
9440 (marker_byte_position): Convert to eassert.
9442 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9444 Simplify list operations in unchain_overlay and unchain_marker.
9445 * buffer.c (unchain_overlay): Simplify. Add comment.
9446 * marker.c (unchain_marker): Simplify. Fix comments.
9448 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9450 Introduce fast path for the widely used marker operation.
9451 * alloc.c (build_marker): New function.
9452 * lisp.h (build_marker): New prototype.
9453 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9454 * composite.c (autocmp_chars): Likewise.

9456 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9457 (save_restriction_save): Use build_marker.
9458 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9459 * window.c (save_window_save): Likewise.
9461 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9463 Do not use Fdelete_overlay in delete_all_overlays
9464 to avoid redundant calls to unchain_overlay.
9465 * buffer.c (drop_overlay): New function.
9466 (delete_all_overlays, Fdelete_overlay): Use it.
9467 * minibuf.c (get_minibuffer): Fix comment.
9469 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9471 Port to OpenBSD 5.1 amd64.
9472 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9473 This is needed for OpenBSD, and should be harmless on all BSD systems.
9474 Also, include <sys/sysctl.h>, as it should be available on all
9475 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9476 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9477 use p_pid member, not kp_proc.pid.
9479 2012-07-06 Glenn Morris <rgm@gnu.org>
9481 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9483 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9485 More xmalloc and related cleanup.
9486 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9494 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9496 Omit needless casts involving void * pointers and allocation.
9497 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9498 as the former is more robust if P's type is changed.
9499 Prefer xzalloc to xmalloc + memset 0.
9500 Simplify malloc-or-realloc to realloc.
9501 Don't worry about xmalloc returning a null pointer.
9502 Prefer xstrdup to xmalloc + strcpy.
9503 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9505 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9506 alloca of a constant.
9508 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9510 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9511 hscroll is larger than the line width. Fixes long and futile
9512 looping inside extend_face_to_end_of_line (on a TTY) producing
9513 glyphs that are not needed and thrown away.
9515 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

9527 not defined (Bug#11768).
9528 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9529 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9530 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9531 followed by gtk_box_set_homogeneous (Bug#11768).
9532 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9533 (update_theme_scrollbar_width, xg_create_scroll_bar):
9534 Use gtk_scrollbar_new (Bug#11768).
9535 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9543 * xdisp.c (window_hscroll_limited): New function.
9544 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9545 coordinates when window's hscroll is set to insanely large
9548 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9550 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9612 Problem reported by Troels Nielsen in
9613 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9617 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9618 This should be fixed in a better way; see Eli Zaretskii in
9619 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9620 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9622 * fileio.c (time_error_value): Rename from special_mtime.
9623 The old name's problems were noted by Eli Zaretskii in
9624 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9626 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9627 This variable's comment says Emacs needs at least one GDB-visible
9628 symbol of type enum pvec_type, to work around GDB problems.
9629 The symbol's value doesn't matter.
9631 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9632 that causes compilation to fail on pre-C99 compilers.
9634 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9636 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9642 headers for buffer_defaults and buffer_local_symbols.
9643 Reported by Juanma Barranquero <lekktu@gmail.com>.

9647 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9648 * lisp.h (enum pvec_type): Use fewer bits.
9649 (PSEUDOVECTOR_SIZE_BITS): New constant.
9650 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9651 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9652 change in pvec_type.
9653 (PSEUDOVECTOR_TYPEP): New macro.

9659 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9660 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9661 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9662 abusing vector->header.next.nbytes.
9663 (live_vector_p): Use PVEC_TYPE.
9664 (mark_object): Adapt code to extract pvectype. Use switch.
9666 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9668 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9669 Tighten new eassert a bit.
9671 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9673 Fix compilation with --enable-gcc-warnings and -O1
9675 * doprnt.c (doprnt): Change type of tem to int, initialize
9676 to avoid compiler warning. Add eassert.
9677 * search.c (simple_search): Initialize match_byte to avoid
9678 compiler warning. Add eassert.
9680 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9682 Avoid weird behavior with large horizontal scrolls.
9683 Without this change, for example, large hscroll values would
9684 mess up Emacs's display on Fedora 15 x86, presumably due to
9685 overflows in int calculations in the display code.
9686 Also, if buffers had long lines, Emacs would freeze.
9687 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9688 (set_window_hscroll): New function, containing the old guts of
9689 Fset_window_hscroll. Return the clipped value.
9690 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9691 This avoids the need to check against PTRDIFF_MAX.
9693 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9695 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9697 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9699 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9701 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9702 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9703 since GCC 4.4.6 issues a bogus warning for them.
9705 Fix bugs in file timestamp newness comparisons.
9706 * fileio.c (Ffile_newer_than_file_p):
9707 * lread.c (Fload): Use full timestamp resolution of files,
9708 not just the 1-second resolution, so that files that are only
9709 slightly newer still count as newer.
9710 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9711 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9713 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9715 * fileio.c: Improve handling of file time marker. (Bug#11852)
9716 (special_mtime): New function.
9717 (Finsert_file_contents, Fverify_visited_file_modtime):
9718 Use it to set special mtime values consistently.
9720 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9722 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9723 marker for non-existing file. (Bug#11852)
9725 2012-07-03 Glenn Morris <rgm@gnu.org>
9727 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9728 and did not make it into globals.h).
9730 2012-07-03 Tom Tromey <tromey@redhat.com>
9732 * window.c (Fset_window_margins, Fset_window_fringes)

9766 * xterm.h: Remove EXFUN.
9768 2012-07-03 Glenn Morris <rgm@gnu.org>
9770 * lisp.h (Frandom): Make it visible to C.
9771 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9772 buffer for invisible buffers. (Bug#1229)
9774 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9776 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9777 values which aren't power of 2.
9778 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9779 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9782 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9784 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9786 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9788 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9790 * alloc.c (allocate_vector_block): Remove redundant
9791 calls to mallopt if DOUG_LEA_MALLOC is defined.
9792 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9793 avoid calls to mallopt if zero_vector is returned.
9795 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9797 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9798 is enabled, avoid dereferencing NULL current_sblock if
9801 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9803 Cleanup basic buffer management.
9804 * buffer.h (struct buffer): Change layout to use generic vector
9805 marking code. Fix some comments. Change type of 'clip_changed'
9806 to bitfield. Remove unused #ifndef old.
9807 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9808 (GET_OVERLAYS_AT): Fix indentation.
9809 (for_each_per_buffer_object_at): New macro.

9812 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9813 * alloc.c (allocate_buffer): Adjust to match new layout of
9814 struct buffer. Fix comment.
9815 (mark_overlay): New function.

9817 Lisp area of struct buffer.
9818 (mark_object): Use it. Adjust marking of misc objects
9819 and related comments.
9821 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9823 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9824 wrapper that is not needed because the wrapped code is a no-op (zero
9825 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9826 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9828 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9830 * alloc.c (mark_buffer): Simplify. Remove prototype.
9831 (mark_object): Add comment. Reorganize marking of vector-like
9832 objects. Use CHECK_LIVE for all vector-like objects except buffers
9833 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9834 Avoid redundant calls to mark_vectorlike for bool vectors.
9836 2012-06-30 Glenn Morris <rgm@gnu.org>
9838 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9840 * epaths.in (PATH_SITELOADSEARCH): New.
9841 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9842 This is rather than relying on --enable-locallisppath elements
9843 having "site-lisp" in their names. (Bug#10208#25, 11658)
9845 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9847 * w32proc.c (sys_select): Accept and ignore one more argument.
9849 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9851 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9852 (pselect) [!MS_DOS]: Redirect to sys_select.
9854 * sysdep.c: Don't include dos.h and dosfns.h.
9856 * process.c (sys_select):
9857 * msdos.c (sys_select): Accept one more argument and ignore it.
9859 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9860 adapt data types and code to that.
9863 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9864 which clashes with the gnulib function of the same name.
9866 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9868 * font.c (font_style_to_value, font_style_symbolic)
9869 (font_prop_validate_style): Add type checks for values in
9872 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9874 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9877 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9879 * xdisp.c (try_window_id): Undo last change.
9881 * w32.c (getwd): Adjust commentary about startup_dir.
9882 (init_environment): Always call sys_access, even in non-MSVC
9883 builds. Don't chdir to the directory of the Emacs executable.
9884 This undoes code from 1997 which was justified by the need to
9885 "avoid conflicts when removing and renaming directories". But its
9886 downside was that every relative file name was being interpreted
9887 relative to the directory of the Emacs executable, which can never
9888 be TRT. In particular, it broke sys_access when called with
9889 relative file names.
9890 (sys_access): Map GetLastError to errno.
9892 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9894 * window.h (struct window): Change type of 'fringes_outside_margins'

9898 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9901 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9903 * gnutls.c (emacs_gnutls_handshake):
9904 Add QUIT to make the loop interruptible.
9906 2012-06-29 Glenn Morris <rgm@gnu.org>
9908 * charset.c (init_charset): Make lack of etc/charsets fatal.
9910 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9912 * editfns.c (region_limit): Fix type mismatch.
9914 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9916 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9917 undefined. Convert from xassert to eassert.
9918 * nsmenu.m: Convert from xassert to eassert.
9919 * nsterm.m: Likewise.
9921 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9923 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9925 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9927 Avoid integer overflow on scroll-left and scroll-right.
9928 * window.c (HSCROLL_MAX): New macro.
9929 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9930 overflow when requested scroll falls outside ptrdiff_t range.
9932 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9934 * window.h (struct window): Change type of 'hscroll',
9935 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9936 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9937 Adjust users accordingly.
9938 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9939 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9940 from EMACS_INT to ptrdiff_t.
9941 (make_window): Omit redundant initialization.
9943 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9945 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9947 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9949 * window.h (struct window): Change type of 'use_time' and
9950 'sequence_number' from Lisp_Object to int.
9951 * frame.c (make_frame): Adjust users accordingly.
9952 * print.c (print_object): Likewise.
9953 * window.c (select_window, Fwindow_use_time, make_parent_window)
9954 (make_window): Likewise.
9956 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9958 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9959 enabled with --enable-checking=[all,glyphs] configure option.
9960 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9961 adjust comments accordingly.
9962 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
9963 undefined, adjust comments accordingly.

10084 Use sprintf return value instead of invoking strlen on result.
10085 In the old days this wasn't portable, since some sprintf
10086 implementations returned char *. But they died out years ago and
10087 Emacs already assumes sprintf returns int.
10088 Similarly for float_to_string.
10089 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10097 Use sprintf or float_to_string result to avoid need to call strlen.
10098 * data.c (Fnumber_to_string):
10099 Use make_unibyte_string, since the string must be ASCII.
10100 * lisp.h, print.c (float_to_string): Now returns int length.
10101 * term.c (produce_glyphless_glyph):
10102 Use sprintf result rather than recomputing it.
10104 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10135 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10137 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10140 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10142 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10143 instead of truncating it to 63 (admittedly a generous limit).

10202 * dispnew.c (Fsleep_for, sit_for):
10203 * keyboard.c (kbd_buffer_get_event):
10204 * process.c (Faccept_process_output):
10205 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10206 This improves on the previous patch, which introduced a bug
10207 when time_t is unsigned and as wide as intmax_t.
10208 See <http://bugs.gnu.org/9000#51>.
10210 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10236 last argument of make_unibyte_string.
10238 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10239 language ID in the event parameters.
10241 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10242 event.code, not the obscure "character set ID".
10244 2012-06-23 Chong Yidong <cyd@gnu.org>

10273 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10275 Support higher-resolution time stamps (Bug#9000).
10276 The time stamps are only nanosecond-resolution at the C level,
10277 since that's the best that any real-world system supports now.
10278 But they are picosecond-resolution at the Lisp level, as that's
10279 easy, and leaves room for future OS improvements.
10281 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10284 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10285 Don't get current time unless it's needed.
10287 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10288 now provides it if it's absent.
10289 (start_atimer): Port to higher-res time stamps.
10290 Check for time stamp overflow. Don't get current time more
10291 often than is needed.
10293 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10294 Include systime.h, not time.h.
10295 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10297 * dired.c: Include stat-time.h.
10298 (Ffile-attributes): File times now have higher resolution.
10300 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10301 (struct image): Timestamp now has higher resolution.
10303 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10304 has at least microseconds now. All uses removed.
10305 (update_frame, update_single_window, update_window, update_frame_1)
10306 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10307 (duration_to_sec_usec): Remove; no longer needed.
10309 * editfns.c (time_overflow): Now extern.
10310 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10311 (float-time, Fformat_time_string, Fcurrent_time_string)

10315 (decode_time_components, lisp_seconds_argument): New functions.
10316 (make_time): Now static.
10317 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10318 Report an error if the time is invalid, rather than having the caller
10321 * fileio.c: Include <stat-time.h>
10322 (Fcopy_file): Copy higher-resolution time stamps.
10323 Prefer to set the time stamp via a file descriptor if that works.
10324 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10325 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10326 (Fvisited_file_modtime, Fset_visited_file_modtime):
10327 Support higher-resolution time stamps.
10329 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10331 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10333 * image.c (prepare_image_for_display, clear_image_cache)
10334 (lookup_image): Port to higer-resolution time stamps.
10336 * keyboard.c (start_polling, bind_polling_period):
10337 Check for time stamp overflow.
10338 (read_char, kbd_buffer_get_event, timer_start_idle)
10339 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10340 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10341 Port to higher-resolution time stamps. Do not assume time_t is signed.
10342 (decode_timer): New function. Timers are now vectors of length 9,
10343 not 8, to accommodate the picosecond component.
10344 (timer_check_2): Use it.
10346 * nsterm.m (select_timeout, timeval_subtract): Remove.
10347 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10348 as they're a bit more accurate and handle overflow better.
10349 (ns_select): Change prototype to be compatible with pselect.
10350 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10351 * nsterm.h (ns_select): Adjust prototype.
10353 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10354 us-resolution time stamps.
10355 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10357 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10359 * lisp.h (time_overflow): New decl.
10360 (wait_reading_process_output): First arg is now intmax_t, not int,
10361 to accommodate larger waits.
10363 * process.h (struct Lisp_Process.read_output_delay):
10364 Now counts nanoseconds, not microseconds.
10365 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10367 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10368 (wait_reading_process_output):
10369 Port to ns-resolution time stamps.
10370 (Faccept_process_output, wait_reading_process_output):
10371 Check for time stamp overflow. Do not assume time_t is signed.
10372 (select_wrapper): Remove; we now use pselect.
10373 (Fprocess_attributes): Now generates ns-resolution time stamps.
10375 * sysdep.c: Include utimens.h. Don't include utime.h
10376 or worry about struct utimbuf; gnulib does that for us now.
10377 (gettimeofday): Remove; gnulib provides a substitute.
10378 (make_timeval): New function.
10379 (set_file_times): Now sets ns-resolution time stamps.
10380 New arg FD; all uses changed.
10381 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10382 (system_process_attributes):
10383 Now returns ns-resolution time stamp. All uses changed.
10384 Check for time stamp overflow.
10386 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10387 provides a substitute now.
10389 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10390 since it guarantees struct timespec.
10391 (EMACS_TIME): Now struct timespec, so that we can support
10392 ns-resolution time stamps.
10393 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10394 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10395 (EMACS_USECS): Remove.
10396 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10397 so multiply the arg by 1000 before storing it.
10398 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10400 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10401 Port to ns-resolution time stamps.
10402 (EMACS_TIME_NEG_P): Remove; replaced by....
10403 (EMACS_TIME_SIGN): New macro.
10404 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10405 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10406 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10407 (make_timeval, make_lisp_time, decode_time_components): New decls.
10408 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10409 that it mishandled time_t overflow. You can't compare by subtracting!
10410 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10411 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10413 * term.c: Include <sys/time.h>.
10414 (timeval_to_Time): New function, for proper overflow wraparound.
10415 (term_mouse_position, term_mouse_click): Use it.
10417 * undo.c (record_first_change): Support higher-resolution time stamps
10418 in the undo buffer.
10419 (Fprimitive_undo): Use them when restoring time stamps.
10421 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10422 (w32_get_internal_run_time):
10423 Port to higher-resolution Emacs time stamps.
10424 (ltime): Now accepts single 64-bit integer, as that's more convenient
10427 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10429 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,

10875 character of length 2: it would truncate after X's first byte
10876 rather than including all of X.

10893 (temacs$(EXEEXT)): Disable memory randomization for the temacs
10894 binary via PaX flags if the paxctl utility is available.
10895 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10896 Restore PaX flags to their default. (Bug#11398)

10900 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10901 buffer (Bug#11226).

10905 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
10906 (note_mode_line_or_margin_highlight): If there is no help echo,
10907 use mode-line-default-help-echo. Handle the case where the mouse
10908 position is past the end of the mode line string.
10910 * buffer.c (buffer_local_value_1): New function, split from
10911 Fbuffer_local_value; can return Qunbound.
10912 (Fbuffer_local_value): Use it.
10913 (Vmode_line_format): Docstring tweaks.
10915 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10927 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10929 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10930 Convert pctcpu and pctmem to Lisp float properly.
10931 Let the compiler fold better, as 100.0/0x8000 is exact.
10933 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10935 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10938 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10942 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10944 For a 'struct window', replace some Lisp_Object fields to
10945 bitfields where appropriate, remove unused fields.
10946 * window.h (struct window): Remove unused 'last_mark_x' and
10947 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

10949 Change type of 'force_start', 'optional_new_start',
10950 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10951 fields from Lisp_Object to bitfield. Adjust users accordingly.
10953 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10955 Pacify gcc -Wdouble-precision when using Xaw.
10956 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10957 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10958 Use 'float' consistently, rather than 'float' in most places
10959 and 'double' in a couple of places.
10961 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10963 * xdisp.c (handle_stop): Detect whether we have overlay strings
10964 loaded by testing it->current.overlay_string_index to be
10965 non-negative, instead of checking whether n_overlay_strings is
10966 positive. (Bug#11587)
10968 2012-05-31 Chong Yidong <cyd@gnu.org>
10970 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10972 * doc.c (Fsubstitute_command_keys): Doc fix.
10974 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10976 * search.c (search_buffer): Remove calls to
10977 r_alloc_inhibit_buffer_relocation, as it is now called by
10978 maybe_unify_char, which was the cause of relocation of buffer text
10981 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10983 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10984 for the duration of call to load_charset, to avoid problems with
10985 callers of maybe_unify_char that access buffer text through C
10988 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10989 decrement the inhibition flag, instead of just setting or
10992 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10994 Remove obsolete '#define static' cruft.
10995 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10996 This #undef was "temporary" in 2000; it is no longer needed
10997 now that '#define static' has gone away.
10998 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10999 (gray_bitmap_bits): Remove; no longer needed.
11000 All uses replaced with definiens.
11001 * xterm.c: Include "bitmaps/gray.xbm".
11003 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11005 Clean up __executable_start, monstartup when --enable-profiling.
11006 The following changes affect the code only when profiling.
11007 * dispnew.c (__executable_start): Rename from safe_bcopy.
11008 Define only on platforms that need it.
11009 * emacs.c: Include <sys/gmon.h> when profiling.
11010 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11011 (__executable_start): Remove decl, since lisp.h does it now.
11012 (safe_bcopy): Remove decl; no longer has that name.
11013 (main): Coalesce #if into single bit of code, for simplicity.
11014 Cast pointers to uintptr_t, since standard libraries want integers
11016 * lisp.h (__executable_start): New decl.
11018 2012-05-31 Glenn Morris <rgm@gnu.org>
11020 * image.c (Fimagemagick_types): Doc fix.
11022 2012-05-30 Jim Meyering <meyering@redhat.com>
11024 * callproc.c (Fcall_process_region): Include directory component
11025 in mkstemp error message (Bug#11586).

11037 (Qdefun): Move from eval.c.
11038 * lisp.h (Qdefun): Remove.
11039 * lread.c (read1): Tiny simplification.
11041 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11043 Do not create empty overlays with the evaporate property (Bug#9642).
11044 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11045 Bug#9642, but explicitly check that the buffer the overlay would
11046 be moved to is live and rearrange lines to make sure that errors
11047 will not put the overlay in an inconsistent state.
11048 (Fdelete_overlay): Cosmetics.
11050 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11052 * w32term.c (my_bring_window_to_top): New function.
11053 (x_raise_frame): Use handle returned by DeferWindowPos, which
11054 could be different from the original one.
11055 Call my_bring_window_to_top instead of my_set_foreground_window.
11058 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11059 by calling BringWindowToTop.

11064 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11066 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11067 This avoids undefined behavior that might cause the eassert
11068 to not catch an out-of-range value.
11070 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11072 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11073 Update dependencies.
11075 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11077 * bidi.c (bidi_mirror_char): Fix last change.
11079 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11081 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11082 when referring to sectname field in printf format.
11084 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11086 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11087 Only r_alloc_inhibit_buffer_relocation needed to be added;
11088 the others were already declared.
11090 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11091 before checking whether it's out of range. Put the check inside
11093 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11095 2012-05-27 Ken Brown <kbrown@cornell.edu>
11097 * callproc.c (Fcall_process): Restore a line that was accidentally
11098 commented out in the 2011-02-13 change (bug#11547).
11100 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11102 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11103 defined on ralloc.c.
11105 * buffer.c [REL_ALLOC]: Remove prototypes of
11106 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11107 they are now on lisp.h.
11109 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11111 * search.c (search_buffer): Use it to inhibit relocation of buffer
11112 text while re_search_2 is doing its job, because re_search_2 is
11113 passed C pointers to buffer text. (Bug#11519)
11115 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11116 Update value to 24.
11118 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11119 state after an additional call to move_it_in_display_line_to, keep
11120 the values of it->max_ascent and it->max_descent found for the
11122 (pos_visible_p): Revert the comparison against bottom_y to what it
11123 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11126 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11128 Fix coding-related core dumps with gcc -ftrapv.
11129 The code was computing A - B, where A and B are pointers, and B is
11130 random garbage. This can lead to core dumps on platforms that
11131 have special pointer registers, and it also leads to core dumps on
11132 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11133 A - B only when B is initialized properly.
11134 * coding.c (coding_set_source, coding_set_destination): Return void.
11135 (coding_change_source, coding_change_destinations): New functions,
11136 with the old behaviors of coding_set_source and coding_set_destination.
11137 All callers that need an offset changed to use these new functions.
11139 2012-05-26 Glenn Morris <rgm@gnu.org>
11141 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11143 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11145 Extend mouse support on W32 text-mode console.
11146 * xdisp.c (draw_row_with_mouse_face):
11147 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11149 * w32console.c: Include window.h.
11150 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11152 (initialize_w32_display): Initialize mouse-highlight data.
11154 * w32inevt.c: Include termchar.h and window.h.
11155 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11156 moves, call note_mouse_highlight. If help_echo changed, call
11157 gen_help_event to produce help-echo message in the echo area.
11158 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11161 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11163 * lread.c (read1): Simplify slightly to avoid an overflow warning
11164 with GCC 4.7.0 on x86-64.
11166 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11168 * bidi.c (bidi_mirror_char): Revert last change: an int is
11169 definitely wide enough here.
11171 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11173 Fix integer width and related bugs (Bug#9874).
11174 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11175 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11176 (string_bytes, check_sblock, allocate_string_data):
11177 (compact_small_strings, Fmake_bool_vector, make_string)
11178 (make_unibyte_string, make_multibyte_string)
11179 (make_string_from_bytes, make_specified_string)
11180 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11181 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11183 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11184 (allocate_pseudovector):
11185 Use int, not EMACS_INT, where int is wide enough.
11186 (inhibit_garbage_collection, Fgarbage_collect):
11187 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11188 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11189 int might not be wide enough.
11190 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11191 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11192 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11193 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11194 (bidi_level_of_next_char, bidi_move_to_visually_next):
11195 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11196 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11197 (Fkill_buffer, Fset_buffer_major_mode)
11198 (advance_to_char_boundary, Fbuffer_swap_text)
11199 (Fset_buffer_multibyte, overlays_at, overlays_in)
11200 (overlay_touches_p, struct sortvec, record_overlay_string)
11201 (overlay_strings, recenter_overlay_lists)
11202 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11203 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11204 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11205 (Foverlay_recenter, last_overlay_modification_hooks_used)
11206 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11207 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11208 (validate_region): Omit unnecessary test for b <= e,
11209 since that's guaranteed by the previous test.
11210 (adjust_overlays_for_delete): Avoid pos + length overflow.
11211 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11212 (report_overlay_modification):
11213 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11214 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11215 Omit pointer cast, which isn't needed anyway, and doesn't work
11216 after the EMACS_INT -> ptrdiff_t change.
11217 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11218 * buffer.h: Adjust decls to match defn changes elsewhere.
11219 (struct buffer_text, struct buffer):
11220 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11221 Use EMACS_INT, not int, where int might not be wide enough.
11222 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11223 not int, to avoid needless 32-bit limit on 64-bit hosts.
11224 (exec_byte_code): Use tighter memory-full test, one that checks
11225 for alloca overflow. Don't compute the address of the object just
11226 before an array, as that's not portable. Use EMACS_INT, not
11227 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11228 * callint.c (Fcall_interactively):
11229 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11230 * callproc.c (call_process_kill, Fcall_process):
11231 Don't assume pid_t fits into an Emacs fixnum.
11232 (call_process_cleanup, Fcall_process, child_setup):
11233 Don't assume pid_t fits into int.
11234 (call_process_cleanup, Fcall_process, delete_temp_file)
11235 (Fcall_process_region):
11236 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11237 (Fcall_process): Simplify handling of volatile integers.
11238 Use int, not EMACS_INT, where int will do.
11239 * casefiddle.c (casify_object, casify_region, operate_on_word)
11240 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11241 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11242 (casify_object): Avoid integer overflow when overallocating buffer.
11243 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11244 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11245 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11246 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11247 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11248 integers are now checked earlier. All uses replaced with XINT.
11250 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11251 For CCL_MapSingle, check that content and value are in int range.
11252 (ccl_driver, Fregister_code_conversion_map):
11253 Check that Vcode_version_map_vector is a vector.
11254 (resolve_symbol_ccl_program): Check that vector header is in range.
11255 Always copy the vector, so that we can check its contents reliably
11256 now rather than having to recheck each instruction as it's being
11257 executed. Check that vector words fit in 'int'.
11258 (ccl_get_compiled_code, Fregister_ccl_program)
11259 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11260 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11261 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11262 contents are in range.
11263 (Fccl_execute_on_string): Check that status is in range.
11264 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11265 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11266 Accept and return EMACS_INT, not int, because callers can pass values
11267 out of 'int' range.
11268 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11269 (multibyte_chars_in_text, parse_str_as_multibyte)
11270 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11271 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11272 (string_escape_byte8, Fget_byte):
11273 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11274 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11275 avoid mishandling large integers.
11276 * character.h: Adjust decls to match defn changes elsewhere.
11277 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11278 (Ffind_charset_region):
11279 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11280 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11281 (load_charset_map_from_vector, Fdefine_charset_internal):
11282 Don't assume fixnum fits in int.
11283 (load_charset_map_from_vector, Fmap_charset_chars):
11284 Remove now-unnecessary CHECK_NATNUMs.
11285 (Fdefine_charset_internal): Check ranges here, more carefully.
11286 Don't rely on undefined behavior with signed left shift overflow.
11287 Don't assume unsigned int fits into fixnum, or that fixnum fits
11288 into unsigned int. Don't require max_code to be a valid fixnum;
11289 that's not true for gb10830 4-byte on a 32-bit host. Allow
11290 invalid_code to be a cons, for the same reason. Require code_offset
11291 to be a character. Avoid int overflow if max_char is close
11293 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11294 this is intended anyway and avoids some undefined behavior.

11965 (handle_one_xevent): NATNUMP can eval its arg twice.
11966 (x_connection_closed):
11967 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11968 * xterm.h: Adjust decls to match defn changes elsewhere.
11969 (struct scroll_bar): Use struct vectorlike_header
11970 rather than rolling our own approximation.
11971 (SCROLL_BAR_VEC_SIZE): Remove; not used.
11973 2012-05-25 Glenn Morris <rgm@gnu.org>
11975 * lisp.mk (lisp): Update for more files being compiled now.
11977 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11979 * lread.c: Remove `read_pure' which makes no difference.
11980 (read_pure): Remove var.
11981 (unreadpure): Remove function.
11982 (readevalloop): Don't call read_list with -1 flag.
11983 (read1, read_vector): Don't test read_pure any more.
11984 (read_list): Simplify.
11986 * fileio.c, character.h: Minor style tweaks.
11988 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
11990 * window.h (clip_changed): Remove useless declaration.
11992 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11994 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11995 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11997 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12000 This directory predates autoconf and is no longer needed nowadays.
12001 Move its few remaining bits of functionality to where they're needed.
12002 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12003 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12004 * m/template.h: Remove.
12005 * Makefile.in (M_FILE): Remove. All uses removed.
12006 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12007 * lisp.h (USE_LSB_TAG):
12008 * mem-limits.h (EXCEEDS_LISP_PTR):
12009 Use VAL_MAX, not VALBITS, in #if.
12010 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12011 (EMACS_UINT): Define unconditionally now.
12012 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12013 (BITS_PER_EMACS_INT): New constants, replacing
12014 what used to be in config.h, but not useful in #if.
12015 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12016 define them any more.
12017 (VAL_MAX): New macro.
12019 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12020 BITS_PER_EMACS_INT, in #if.
12021 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12022 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12023 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12024 * s/ms-w32.h (DATA_START):
12025 Move here from removed file m/intel386.h.
12026 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12027 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12029 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12031 Assume C89 or later.
12032 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12033 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12035 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12036 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12037 * textprop.c, tparam.c (NULL): Remove.
12038 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12039 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12040 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12041 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12042 * xterm.c (input_signal_count): Assume volatile works.
12044 2012-05-21 Ken Brown <kbrown@cornell.edu>
12046 * xgselect.c (xg_select): Fix first argument in call to 'select'
12049 2012-05-20 Ken Brown <kbrown@cornell.edu>
12051 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12052 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12054 2012-05-19 Ken Brown <kbrown@cornell.edu>
12056 * xfns.c (x_in_use): Remove `static' qualifier.
12057 * xterm.h (x_in_use): Declare.
12058 * xgselect.c: Include xterm.h.
12059 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12060 and `display_arg' (bug#9754).
12062 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12064 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12066 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12067 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12069 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12071 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12073 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12074 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12076 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12077 reference to image_cache->refcount.
12078 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12080 2012-05-17 Juri Linkov <juri@jurta.org>
12082 * search.c (Fword_search_regexp, Fword_search_backward)
12083 (Fword_search_forward, Fword_search_backward_lax)
12084 (Fword_search_forward_lax): Move functions to isearch.el
12085 (bug#10145, bug#11381).
12087 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12089 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12091 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12093 * lread.c (init_obarray): Declare Qt and Qnil as special.
12095 2012-05-14 Glenn Morris <rgm@gnu.org>
12097 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12098 Put "libexec" before "bin", for the sake of init_callproc_1.
12100 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12102 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12104 * unexaix.c: Port to more-recent AIX compilers.
12105 (report_error, report_error_1, make_hdr, copy_sym)
12106 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12107 Make arguments const char *, not char *, to avoid violations of C
12108 standard and to fix some AIX warnings reported by Gilles Pion.
12110 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12112 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12113 already have overlays loaded.
12114 (handle_single_display_spec): Before returning without displaying
12115 fringe bitmap, synchronize the bidi iterator with the main display
12116 iterator, by calling iterate_out_of_display_property.
12117 (iterate_out_of_display_property): Detect buffer iteration by
12118 testing that it->string is a Lisp string.
12119 (get_next_display_element): When the current object is exhausted,
12120 and there's something on it->stack, call set_iterator_to_next to
12121 proceed with what's on the stack, instead of returning zero.
12122 (set_iterator_to_next): If called at the end of a Lisp string,
12123 proceed to consider_string_end without incrementing string
12124 position. Don't increment display vector index past the end of
12125 the display vector. (Bug#11417)
12126 (pos_visible_p): Don't report a position visible when move_it_to
12127 stopped at the last line of window, which happens to be scanned
12128 backwards by the bidi iteration. (Bug#11464)
12130 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12132 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12133 and right-margin display specs even if the spec is invalid or we
12134 are on a TTY, and thus unable to display on the fringes.
12135 That's because the text with the property will not be displayed anyway,
12136 so we need to signal to the caller that this is a "replacing"
12137 display spec. This fixes display when the spec is invalid or we
12140 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12142 * unexaix.c (make_hdr): Fix typo in prototype.
12143 This bug broke the build on AIX. Problem reported by Gilles Pion.
12145 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12147 * keyboard.c (kbd_buffer_get_event): Read special events also in
12148 batch mode. (Bug#11415)
12150 2012-05-12 Glenn Morris <rgm@gnu.org>
12152 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12154 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12156 * lisp.mk (lisp): Add newcomment.elc.
12158 2012-05-12 Glenn Morris <rgm@gnu.org>
12160 * Makefile.in (MKDIR_P): New, set by configure.
12161 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12163 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12165 Remove unused function hourglass_started.
12166 * dispextern.h (hourglass_started):
12167 * w32fns.c (hourglass_started):
12168 * xdisp.c (hourglass_started): Remove.
12170 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12172 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12173 Update dependencies.
12175 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12177 * xgselect.c (xg_select): Put maxfds+1 into a var.
12178 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12180 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12182 2012-05-10 Dave Abrahams <dave@boostpro.com>
12184 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12185 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12187 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12189 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12190 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12191 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12192 Initialize xd_registered_buses.
12194 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12196 Untag more efficiently if USE_LSB_TAG.
12197 This is based on a proposal by YAMAMOTO Mitsuharu in
12198 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12199 For an admittedly artificial (nth 8000 longlist) benchmark on
12200 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12201 Emacs's overall text size by 1%.
12202 * lisp.h (XUNTAG): New macro.
12203 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12204 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12205 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12206 * eval.c (Fautoload):
12207 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12208 * frame.h (XFRAME): Use XUNTAG.
12210 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12211 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12212 Remove unportable assumptions about print widths of types like
12214 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12215 intptr_t when converting between pointer and integer, to avoid GCC
12216 warnings about wrong width.
12218 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12220 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12221 stack for each reader_thread, instead of defaulting to 8MB
12222 determined by the linker. This avoids failures in creating
12223 subprocesses on Windows 7, see the discussion in this thread:
12224 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12226 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12228 Fix up display of the *Minibuf-0* buffer in the mini window.
12229 * keyboard.c (read_char): Don't clear the echo area if there's no
12231 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12232 contents of *Minibuf-0*) if there's no message displayed in its stead.
12234 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12236 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12239 2012-05-06 Chong Yidong <cyd@gnu.org>
12241 * lisp.mk (lisp): Update.
12243 2012-05-05 Jim Meyering <meyering@redhat.com>
12245 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12247 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12249 * data.c (PUT_ERROR): New macro.
12250 (syms_of_data): Use it. Add new error type `user-error'.
12251 * undo.c (user_error): New function.
12252 (Fprimitive_undo): Use it.
12253 * print.c (print_error_message): Adjust print style for `user-error'.
12254 * keyboard.c (user_error): New function.
12255 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12257 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12259 Do not limit current-time-string to years 1000..9999.
12260 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12261 (Fcurrent_time_string): Support any year that is supported by the
12262 underlying localtime representation. Don't use asctime, as it
12263 has undefined behavior for years outside the range -999..9999.
12265 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12267 Fix race conditions involving setenv, gmtime, localtime, asctime.
12268 Without this fix, interrupts could mess up code that uses these
12269 nonreentrant functions, since setting TZ invalidates existing
12270 tm_zone or tzname values, and since most of these functions return
12271 pointers to static storage.
12272 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12273 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12274 Grow the critical sections to include not just invoking
12275 localtime/gmtime, but also accessing these functions' results
12276 including their tm_zone values if any, and any related TZ setting.
12277 (format_time_string): Last arg is now struct tm *, not struct tm **,
12278 so that the struct tm is saved in the critical section.
12279 All callers changed. Simplify allocation of initial buffer, partly
12280 motivated by the fact that memory allocation needs to be outside
12281 the critical section.
12283 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12285 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12286 with RESET_INTERVAL.
12288 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12289 Remove duplicated buffer name initialization.
12291 2012-05-02 Jim Meyering <jim@meyering.net>
12293 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12295 * xfns.c (x_window): Use xstrdup (Bug#11375).
12297 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12299 * xdisp.c (pos_visible_p): If already at a newline from the
12300 display string before the 'while' loop, don't walk back the glyphs
12301 from it3.glyph_row. Solves assertion violation when the display
12302 string begins with a newline (egg.el). (Bug#11367)
12304 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12306 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12309 2012-05-01 Glenn Morris <rgm@gnu.org>
12311 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12312 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12313 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12314 All were removed before 23.1.
12316 * dispnew.c: Remove HAVE_LIBNCURSES test;
12317 it is always true on relevant platforms.
12319 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12320 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12322 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12324 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12326 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12327 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12330 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12332 Do not avoid creating empty evaporating overlays (Bug#9642).
12333 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12334 That is, do not delete an evaporating overlay if it becomes
12335 empty after its bounds are adjusted to fit within its buffer.
12336 This fix caused other problems, and I'm reverting it until we get
12337 to the bottom of them.
12339 2012-04-27 Chong Yidong <cyd@gnu.org>
12341 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12343 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12345 * xdisp.c (pos_visible_p): If the window start position is beyond
12346 ZV, start the display from buffer beginning. Prevents assertion
12347 violation in init_iterator when the minibuffer window is scrolled
12348 via the scroll bar.
12350 * window.c (window_scroll_pixel_based): Likewise.
12352 2012-04-27 Chong Yidong <cyd@gnu.org>
12354 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12356 2012-04-27 Glenn Morris <rgm@gnu.org>
12358 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12359 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12361 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12363 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12364 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12366 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12368 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12369 display element, check also the underlying string or buffer
12370 character. (Bug#11341)
12372 * w32menu.c: Include w32heap.h.
12373 (add_menu_item): If the call to AppendMenuW (via
12374 unicode_append_menu) fails, disable Unicode menus only if we are
12375 running on Windows 9X/Me.
12377 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12379 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12380 (xgetint): Add missing shift for LSB tags.
12382 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12384 * keyboard.c (read_char): Don't wipe echo area for select window
12385 events: These might get delayed via `mouse-autoselect-window'
12388 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12390 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12391 manipulation of :loaded-from data.
12393 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12395 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12396 now a cons (bug#11311).
12398 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12400 Do not create empty overlays with the evaporate property (Bug#9642).
12401 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12402 if it becomes empty after its bounds are adjusted to fit within
12403 its buffer. Without this fix, in a nonempty buffer (let ((o
12404 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12405 yields an empty overlay that has the evaporate property, which is
12406 not supposed to happen.
12408 Fix minor GTK3 problems found by static checking.

12610 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12611 (NEED_MEM_INSERT): New macro.
12612 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12613 Remove one incorrect comment and fix another.

12680 2012-04-11 Daniel Colascione <dancol@dancol.org>
12682 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12683 against is gone. It's better to use vfork now so that when Cygwin
12684 gains a new, working vfork, we use it automatically (bug#10398).
12686 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12739 * minibuf.c (Fread_variable): Callers changed.
12741 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12743 * xdisp.c (set_cursor_from_row): If the display string appears in
12744 the buffer at position that is closer to point than the position
12745 after the display string, display the cursor on the first glyph of
12746 the display string. Fixes cursor display when a 'display' text
12747 property immediately follows invisible text. (Bug#11094)
12749 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12751 composite.c: use 'double' consistently
12752 * composite.c (get_composition_id): Use 'double' consistently
12753 instead of converting 'float' to 'double' and vice versa; this is
12754 easier to understand and avoids a GCC warning.
12756 2012-04-09 Glenn Morris <rgm@gnu.org>

12808 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12810 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

12823 point, use it.vpos to compute how many lines to backtrack after
12824 move_it_to point. (Bug#11133)
12826 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12828 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12829 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12830 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12831 macros related to unification of CJK characters. For the details,
12832 see the discussion following the message here:

12839 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12841 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12842 instead of alloca. (Bug#11138)
12844 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12846 * w32menu.c (is_simple_dialog): Properly check lisp types.
12849 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12851 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12852 position we get to after a call to move_it_to fails the
12853 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12854 only if we wind up in a string from display property. (Bug#11063)
12856 * window.c (Fdelete_other_windows_internal): Invalidate the row
12857 and column information about mouse highlight, so that redisplay
12858 restores it after reallocating the glyph matrices. (Bug#7464)
12860 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12861 string comes from a `display' text property, use the buffer
12862 position of that property as if we actually saw that position in
12864 (move_it_by_lines): Remove the assertion that
12865 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12866 violated when there's a before-string at the beginning of a line.
12869 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12871 * xdisp.c (append_space_for_newline): If the default face was
12872 remapped, use the remapped face for the appended newline.
12873 (extend_face_to_end_of_line): Use the remapped default face for
12874 extending the face to the end of the line.
12875 (display_line): Call extend_face_to_end_of_line when the default
12876 face was remapped. (Bug#11068)
12878 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12880 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12882 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12884 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12886 2012-03-27 Glenn Morris <rgm@gnu.org>
12888 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12891 2012-03-26 Kenichi Handa <handa@m17n.org>
12893 * dispextern.h (struct glyph): Fix previous change. Change the
12894 bit length of glyphless.ch to 25 (Bug#11082).
12896 2012-03-26 Chong Yidong <cyd@gnu.org>
12898 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12899 (command_loop_1): Use it; inhibit selection update for
12900 handle-select-window too (Bug#8996).
12902 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12904 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12906 2012-03-25 Kenichi Handa <handa@m17n.org>
12908 * dispextern.h (struct glyph): Change the bit length of
12909 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12911 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12913 * s/ms-w32.h (tzname): Include time.h before redirecting to
12914 _tzname. Fixes the MSVC build. (Bug#9960)
12916 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12918 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12921 * xterm.c (XTread_socket): Only modify handling_signal if
12922 !SYNC_INPUT. (Bug#11080)
12924 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12926 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12927 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12928 when fetching a multibyte character consumes more bytes than
12929 CHAR_BYTES returns, due to unification of CJK characters in
12930 string_char. (Bug#11073)
12932 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12934 * process.c (wait_reading_process_output): Handle pty disconnect
12935 by refraining from sending oneself a SIGCHLD (bug#10933).
12937 2012-03-22 Chong Yidong <cyd@gnu.org>
12939 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12941 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12942 Mark string as coming from a prefix property.
12943 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12944 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12946 2012-03-21 Chong Yidong <cyd@gnu.org>
12948 * xfaces.c (Vface_remapping_alist): Doc fix.
12950 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12952 * w32proc.c (Fw32_set_console_codepage)
12953 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12956 2012-03-20 Chong Yidong <cyd@gnu.org>
12958 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12959 to reflect default non-nil value of redisplay-dont-pause.
12961 2012-03-19 Kenichi Handa <handa@m17n.org>
12963 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12964 it fit in a valid range (Bug#11003).
12966 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12968 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12969 that is not from display property, accept the row as a "cursor
12970 row" if one of the string's character has a non-nil `cursor'
12971 property. Fixes cursor positioning when there are newlines in
12972 overlay strings, e.g. in icomplete.el. (Bug#11035)
12974 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12976 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12978 2012-03-12 Chong Yidong <cyd@gnu.org>
12980 * eval.c (inhibit_lisp_code): Rename from
12981 inhibit_window_configuration_change_hook; move from window.c.
12983 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12984 * window.c (run_window_configuration_change_hook)
12985 (syms_of_window): Callers changed.
12987 2012-03-11 Chong Yidong <cyd@gnu.org>
12989 * keymap.c (Fkey_description): Doc fix (Bug#9700).
12991 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12993 2012-03-10 Chong Yidong <cyd@gnu.org>
12995 * frame.c (other_visible_frames): Don't assume the selected frame
12996 is visible (Bug#10955).
12998 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13000 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13002 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13004 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13005 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13008 2012-03-03 Glenn Morris <rgm@gnu.org>
13010 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13012 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13014 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13015 position past the first glyph_row that ends at ZV. (Bug#10902)
13016 (redisplay_window, next_element_from_string): Fix typos in
13018 (redisplay_window): Pass to move_it_vertically the margin in
13019 pixels, not in screen lines.
13021 2012-03-02 Glenn Morris <rgm@gnu.org>
13023 * buffer.c (buffer-list-update-hook): Doc fix.
13025 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13027 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13028 push_it before setting up the iterator for the first overlay
13029 string, even if we have an empty string loaded.
13030 (next_overlay_string): If there's an empty string on the iterator
13031 stack, pop the stack. (Bug#10903)
13033 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13035 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13036 Suggested by Stefan Monnier in
13037 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13038 * alloc.c (widen_to_Lisp_Object): New static function.
13039 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13040 and widening them to Lisp_Objects. This would work even if
13041 USE_LSB_TAG is defined and wide integers are used, which might
13042 happen in a future version of Emacs.
13044 2012-02-25 Chong Yidong <cyd@gnu.org>
13046 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13049 * xselect.c (Fx_selection_exists_p): Doc fix.
13050 (x_clipboard_manager_save_all): Print an informative message
13051 before saving to clipboard manager.
13053 2012-02-24 Chong Yidong <cyd@gnu.org>
13055 * keyboard.c (process_special_events): Handle all X selection
13056 requests in kbd_buffer, not just the next one (Bug#8869).
13058 2012-02-23 Chong Yidong <cyd@gnu.org>
13060 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13061 call when setting menu-bar-lines and tool-bar-lines parameters.
13062 (unwind_create_frame_1): New helper function.
13064 * window.c (inhibit_window_configuration_change_hook): New var.
13065 (run_window_configuration_change_hook): Obey it.
13066 (syms_of_window): Initialize it.
13068 2012-02-22 Chong Yidong <cyd@gnu.org>
13070 * xterm.c (x_draw_image_relief): Add missing type check for
13071 Vtool_bar_button_margin (Bug#10743).
13073 2012-02-21 Chong Yidong <cyd@gnu.org>
13075 * fileio.c (Vfile_name_handler_alist): Doc fix.
13077 * buffer.c (Fget_file_buffer): Protect against invalid file
13078 handler return value.
13080 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13082 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13083 when computing $valmask.
13085 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13086 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13087 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13088 It's useless in that case, and it can cause problems on hosts
13089 that allocate halves of EMACS_INT values separately.
13090 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13091 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13092 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13093 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13094 it avoids undefined behavior on hosts where shifting right by more
13095 than the word width has undefined behavior.
13097 2012-02-19 Chong Yidong <cyd@gnu.org>
13099 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13100 (Funhandled_file_name_directory, Ffile_name_as_directory)
13101 (Fdirectory_file_name, Fexpand_file_name)
13102 (Fsubstitute_in_file_name): Protect against invalid file handler
13103 return values (Bug#10845).
13105 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13107 * .gdbinit (pitx): Fix incorrect references to fields of the
13110 2012-02-17 Chong Yidong <cyd@gnu.org>

13117 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13119 2012-02-15 Chong Yidong <cyd@gnu.org>
13121 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13122 marked as special. Also, starting docstrings with * is obsolete.
13124 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13126 * gnutls.c (emacs_gnutls_write): Fix last change.

13130 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
13133 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
13135 * keymap.c (Fsingle_key_description): Handle char ranges.
13137 2012-02-12 Chong Yidong <cyd@gnu.org>
13139 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13140 as that creates a dangerous corner case.
13142 * window.c (Fdelete_window_internal): Invalidate the mouse
13143 highlight (Bug#9904).
13145 2012-02-12 Glenn Morris <rgm@gnu.org>
13147 * xselect.c (Fx_own_selection_internal)
13148 (Fx_get_selection_internal, Fx_disown_selection_internal)
13149 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13150 * nsselect.m (Fx_own_selection_internal)
13151 (Fx_disown_selection_internal, Fx_selection_exists_p)
13152 (Fx_selection_owner_p, Fx_get_selection_internal):
13153 Sync docs and argument specs with the xselect.c versions.
13155 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13157 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13159 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13161 * w32select.c (Fx_selection_exists_p): Sync doc string and
13162 argument list with xselect.c. (Bug#10783)
13164 * w16select.c (Fx_selection_exists_p): Sync doc string and
13165 argument list with xselect.c. (Bug#10783)

13171 2012-02-09 Kenichi Handa <handa@m17n.org>
13173 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13175 2012-02-07 Chong Yidong <cyd@gnu.org>
13177 * buffer.c (Fbuffer_local_variables)
13178 (buffer_lisp_local_variables): Handle unbound vars correctly;
13179 don't let Qunbound leak into Lisp.
13181 2012-02-07 Glenn Morris <rgm@gnu.org>
13183 * image.c (Fimagemagick_types): Doc fix.
13185 * image.c (imagemagick-render-type): Change it from a lisp object
13186 to an integer. Move the doc here from the lisp manual.
13187 Treat all values not equal to 0 the same.
13189 2012-02-06 Chong Yidong <cyd@gnu.org>
13191 * doc.c (store_function_docstring): Avoid applying docstring of
13192 alias to base function (Bug#2603).

13203 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13205 * w32.c (get_emacs_configuration_options):
13206 Include --enable-checking, if specified, in the return value.
13208 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13210 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13211 after rounding frame sizes. (Bug#9723)
13213 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13215 * keyboard.c (adjust_point_for_property): Don't position point
13216 before BEGV. (Bug#10696)
13218 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13220 Handle overflow when computing char display width (Bug#9496).
13221 * character.c (char_width): Return EMACS_INT, not int.
13222 (char_width, c_string_width): Check for overflow when
13223 computing the width; this is possible now that individual
13224 characters can have unbounded width. Problem introduced
13225 by merge from Emacs 23 on 2012-01-19.
13227 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13229 * dbusbind.c (Fdbus_register_method): Mention the return value
13230 :ignore in the docstring.
13232 2012-02-02 Glenn Morris <rgm@gnu.org>
13234 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
13236 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13242 2012-02-02 Kenichi Handa <handa@m17n.org>
13244 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13245 0, do not call append_composite_glyph.
13247 2012-02-02 Kenichi Handa <handa@m17n.org>
13249 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13251 (x_produce_glyphs): If the component of a composition is a null
13252 string, set it->pixel_width to 1 to avoid zero-width glyph.
13254 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13256 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13257 first 2 arguments are identical. This makes inserting large
13258 output from a subprocess an order of magnitude faster on
13259 MS-Windows, where all sbrk'ed memory is always contiguous.
13261 2012-01-31 Glenn Morris <rgm@gnu.org>
13263 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13299 2012-01-21 Chong Yidong <cyd@gnu.org>
13301 * floatfns.c (Fcopysign): Make the second argument non-optional,
13302 since nil is not allowed anyway.
13304 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13306 * process.c (read_process_output): Use p instead of XPROCESS (proc).
13307 (send_process): Likewise.
13309 2012-01-19 Martin Rudalics <rudalics@gmx.at>
13311 * window.c (save_window_save, Fcurrent_window_configuration)
13312 (Vwindow_persistent_parameters): Do not use Qstate.
13313 Rewrite doc-strings.
13315 2012-01-19 Kenichi Handa <handa@m17n.org>
13317 * character.c (char_width): New function.
13318 (Fchar_width, c_string_width, lisp_string_width):
13319 Use char_width (Bug#9496).
13321 2012-01-16 Martin Rudalics <rudalics@gmx.at>
13323 * window.c (Vwindow_persistent_parameters): New variable.
13324 (Fset_window_configuration, save_window_save): Handle persistent

13874 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13875 Otherwise, valgrind does not work on some platforms.
13876 Problem reported by Andreas Schwab in
13877 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13878 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13879 is set, removing the need for VIRT_ADDRESS_VARIES.
13880 (PURE_P): Use a more-efficient implementation that needs just one
13881 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13882 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13883 to 4 (xorl, subq, cmpq, setbe).
13884 * alloc.c (pure): Always extern now, since that's the
13885 VIRT_ADDR_VARIES behavior.
13886 (PURE_POINTER_P): Use a single comparison, not two, for
13887 consistency with the new puresize.h.
13888 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13889 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13897 behave as if the cursor position were at the window margin.
13899 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13900 and the cursor position is out of bounds, behave as if the cursor
13901 position were at the window margin. (Bug#10075)
13903 2011-11-18 Chong Yidong <cyd@gnu.org>
13905 * window.c (Fwindow_combination_limit): Make first argument

13927 compute_line_metrics.
13928 (compute_line_metrics): Call row_hash, instead of computing the
13931 * dispnew.c (verify_row_hash): Call row_hash for computing the
13932 hash code of a row, instead of duplicating code from xdisp.c.
13934 * dispextern.h (row_hash): Add prototype.
13936 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13972 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13974 * xdisp.c (display_line): Move the call to
13975 highlight_trailing_whitespace before the call to
13976 compute_line_metrics, since the latter needs to see the final
13977 faces of all the glyphs to compute ROW's hash value.
13978 Fixes assertion violations in row_equal_p. (Bug#10035)
13980 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13982 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

13987 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13988 with user-defined heap size. Bump the default size of the temacs

13992 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13993 current_matrix and desired_matrix. (Bug#9990)
13994 (verify_row_hash) [XASSERTS]: New function.

14041 Avoid some portability problems by eschewing 'extern inline' functions.
14042 The trivial performance wins aren't worth the portability hassles; see

14111 * xmenu.c (cleanup_widget_value_tree): New function.
14112 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14119 (window_box_width, window_box_left, window_box_left_offset)
14120 (window_box_right, window_box_right_offset): Declare extern.
14121 Otherwise, these inline functions do not conform to C99 and
14122 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14123 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14124 * intervals.c (adjust_intervals_for_insertion)

14127 (static_offset_intervals): Remove.
14128 (offset_intervals): Rewrite using the old contents of
14129 static_offset_intervals. The old version didn't conform to C99

14253 2011-11-03 Eli Zaretskii <eliz@gnu.org>
14255 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
14257 * w32fns.c (unwind_create_frame): If needed, free the glyph
14258 matrices of the partially constructed frame. (Bug#9943)
14259 * xfns.c (unwind_create_frame): Likewise.
14261 2011-11-01 Eli Zaretskii <eliz@gnu.org>
14263 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
14264 Don't stop backward scan on the continuation glyph, even though
14265 its CHARPOS is positive.
14266 (mouse_face_from_buffer_pos, note_mouse_highlight):
14267 Rename cover_string to disp_string.
14269 2011-11-01 Martin Rudalics <rudalics@gmx.at>
14271 * window.c (temp_output_buffer_show): Don't use
14272 Vtemp_buffer_show_specifiers.
14273 (Vtemp_buffer_show_specifiers): Remove unused variable.
14275 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14277 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14278 past the beginning of the current glyph matrix.
14280 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14282 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14283 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14284 HAVE_GTK3 (Bug#9869).
14286 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
14287 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14289 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14291 * xterm.c: Declare x_handle_net_wm_state to return int.
14292 (handle_one_xevent): Check if we are iconified but don't have
14293 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14294 (get_current_wm_state): Return non-zero if not hidden,
14295 check for _NET_WM_STATE_HIDDEN (Bug#9893).
14296 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
14297 (x_handle_net_wm_state): Return what get_current_wm_state returns.
14298 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
14300 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14302 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14303 so that this new function doesn't get optimized away by a
14304 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14306 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14308 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14310 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14312 Fix the `xbytecode' command.
14313 * .gdbinit (xprintbytestr): New command.
14314 (xwhichsymbols): Rename from `which'; all callers changed.
14315 (xbytecode): Print the byte-code string as well.
14317 2011-10-29 Kim Storm <storm@cua.dk>
14319 * alloc.c (which_symbols): New function.
14321 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14323 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14326 2011-10-29 Glenn Morris <rgm@gnu.org>
14328 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14329 Not clear what it was for, and it causes various bugs. (Bug#9839)
14331 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14333 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14334 possible random value that matches one of those tested as
14335 condition to clear the mouse face.
14337 2011-10-28 Chong Yidong <cyd@gnu.org>
14339 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14341 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14343 * window.c (make_window): Initialize phys_cursor_on_p.
14345 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14347 * lisp.h (struct Lisp_Symbol): Update comments.
14349 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14351 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14353 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14355 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14356 <oslsachem@gmail.com> for helping to debug this.
14358 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14359 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14360 (g_b_init_get_glyph_outline_w): New static variables.
14361 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14362 (GetGlyphOutlineW_Proc): New typedefs.
14363 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14364 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14366 (w32font_open_internal, compute_metrics):
14367 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14368 instead of calling the "wide" APIs directly.
14370 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14372 * w32.h (syms_of_w32font): Add prototype.
14374 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14376 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14377 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14378 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14379 (Fmove_to_window_line): Doc fix.
14381 2011-10-27 Chong Yidong <cyd@gnu.org>
14383 * process.c (make_process): Set gnutls_state to NULL.
14385 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14386 non-NULL, regardless of GNUTLS_INITSTAGE.
14387 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14388 an error. Set process slots as soon as we allocate them.
14390 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14392 2011-10-27 Chong Yidong <cyd@gnu.org>
14394 * gnutls.c (emacs_gnutls_deinit): New function.
14395 Deallocate credentials structures as well as calling gnutls_deinit.
14396 (Fgnutls_deinit, Fgnutls_boot): Use it.
14398 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14399 (deactivate_process): Call emacs_gnutls_deinit.
14401 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14403 * image.c (x_create_x_image_and_pixmap):
14404 * w32.c (sys_rename, w32_delayed_load):
14405 * w32font.c (fill_in_logfont):
14406 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14408 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14410 * w32fns.c (w32_default_color_map): New function,
14411 extracted from Fw32_default_color_map.
14412 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14414 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14416 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14418 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14420 * keyboard.c (test_undefined): New function (bug#9751).
14421 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14423 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14425 * sysdep.c (init_sys_modes): Fix the check for the controlling
14426 terminal (Bug#6649).
14428 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14430 * dispextern.h (struct bidi_it): New member next_en_type.
14432 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14433 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14434 current character, check also for next_en_type being WEAK_EN.
14435 (bidi_resolve_weak): Don't enter the expensive loop if the current
14436 position is before next_en_pos. Record the bidi type of the first
14437 non-ET, non-BN character we find, in addition to its position.
14438 (bidi_level_of_next_char): Invalidate next_en_type when
14439 next_en_pos is over-stepped.
14441 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14443 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14444 * editfns.c: Rewrite current-time-zone so that it invokes
14445 the equivalent of (format-time-string "%Z") to get the time zone name.
14446 This fixes a bug when the time zone name contains characters that
14447 need converting from the system time locale to Emacs internal format.
14448 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14449 that patch fixed format-time-string to do the conversion, but
14450 I forgot to fix current-time-zone.
14451 (format_time_string): New function, containing most of
14452 what Fformat_time_string used to contain.
14453 (Fformat_time_string): Rewrite in terms of format_time_string.
14454 This doesn't change this function's behavior.
14455 (current-time-zone): Rewrite to use format_time_string.
14456 This fixes the bug reported by Michael Schierl in
14457 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14458 Jason Rumney's 2007-06-07 change worked around this bug, but
14460 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14462 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14464 * xdisp.c (start_display): If the character at POS is displayed
14465 via a display vector, reset IT->current.dpvec_index to zero.
14466 (try_window_reusing_current_matrix): If a line ends in a display
14467 vector or the next line starts in a display vector, continue
14468 redrawing the window even though the character position of
14469 start_row was reached.
14472 2011-10-18 Chong Yidong <cyd@gnu.org>
14474 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14475 with nobreak-char-display too.
14477 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14479 Fix part 3 of bug#9771.
14480 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14481 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14482 non-neutral characters if the current character is a paragraph
14483 separator (a.k.a. Newline). This avoids running the same
14484 expensive loop twice, once when we consume the preceding newline
14485 and the other time when the line actually needs to be displayed.
14486 Avoid the loop when we see neutrals on the base embedding level
14487 following a character whose directionality is the same as the
14488 paragraph's. This avoids running the expensive loop when a line
14489 ends in a long sequence of neutrals, like control characters.
14490 Add assertion against STRONG_AL type. Slightly rearrange code
14491 that determines the type of a neutral given the first non-neutral
14493 (bidi_level_of_next_char): Set next_en_pos to zero when
14494 invalidating its info.
14496 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14498 * xdisp.c (push_display_prop): Determine whether to record string
14499 or buffer position by IT->string, not by IT->method. Allow
14500 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14501 (move_it_vertically_backward): Don't look for character position
14502 immediately after the newline when in a continuation line.
14505 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14507 * window.c (coordinates_in_window): Rewrite and delabelize
14508 vertical border check. (Bug#5357) (Bug#9618)
14510 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14512 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14513 errors in XSetWindowBorder (bug#9310).
14515 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14517 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14518 avoid crash when xmalloc overrun checking is enabled.
14520 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14522 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14523 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14524 cursor motion with <left> and <right> arrow keys.
14526 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14527 some callers set that themselves.
14529 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14531 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14532 display string and the previous row comes from the same string and
14533 is empty. (Bug#9739) (Bug#9738)
14535 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14537 * doc.c (get_doc_string): Encode file name (bug#9735).
14539 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14541 * bidi.c (bidi_level_of_next_char):
14542 * xdisp.c (get_visually_first_element): Remove old incorrect
14543 comments regarding the Unicode Line Separator character.
14545 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14547 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14549 * alloc.c (Fgc_status): Do not access beyond zombies array
14550 boundary if nzombies > MAX_ZOMBIES.
14551 * alloc.c (dump_zombies): Add missing format specifier.
14553 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14555 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14556 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14558 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14559 Some packages use them to denote characters with modifiers.
14561 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14563 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14564 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14565 matching a pp-number. Rename parameter var to var1.
14567 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14569 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14571 2011-10-08 Glenn Morris <rgm@gnu.org>
14573 * callint.c (Fcall_interactively): Give a more explicit error for the
14574 'c' case with a non-character input. (Bug#8479)
14576 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14578 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14580 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14581 lines that are hscrolled on the left.
14583 * dispnew.c (buffer_posn_from_coords): Account for a possible
14584 presence of header-line. (Bug#4426)
14586 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14588 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14589 Don't advertise functionality which we discourage or doesn't work.
14591 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14593 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14594 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14595 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14596 this makes Emacs dump core during garbage collection on rare
14597 occasions. sizeof is obviously inferior to offsetof here, so
14598 stick with offsetof.
14599 (GC_POINTER_ALIGNMENT): New macro.
14600 (mark_memory): Omit 3rd (offset) arg; caller changed.
14601 Don't assume EMACS_INT alignment is the same as pointer alignment.
14603 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14605 * keyboard.c (read_key_sequence_remapped): New var.
14606 (read_key_sequence): Compute remapping in the right buffer.
14607 (command_loop_1): Use read_key_sequence's remapping directly.
14609 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14611 * dired.c (file_name_completion): Don't expand file name.
14612 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14613 before checking file name handler.
14615 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14616 they've been requested explicitly (bug#9591).
14618 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14620 * keymap.c (Fsingle_key_description): Use make_specified_string
14621 instead of build_string to build string from push_key_description.
14624 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14626 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14627 This fixes a Y2038 bug on 64-bit hosts.
14628 * buffer.c (reset_buffer):
14629 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14630 (Fclear_buffer_auto_save_failure):
14631 Use 0, not -1, to represent an unset failure time, since time_t
14632 might not be signed.
14634 Remove dependency on glibc malloc internals.
14635 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14636 Move back here from lisp.h, but with their new implementations.
14637 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14638 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14639 * charset.c (charset_table_init): New static var.
14640 (syms_of_charset): Use it instead of xmalloc. This removes a
14641 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14642 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14643 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14644 Move back to alloc.c.
14645 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14646 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14648 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14650 * nsterm.m (windowDidResize): Call x_set_window_size only when
14651 ns_in_resize is true. Otherwise set pixelwidth/height and
14652 call change_frame_size (Bug#9628).
14654 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14656 Port --enable-checking=all to Fedora 14 x86-64.
14657 * charset.c (syms_of_charset): Also account for glibc malloc's
14658 internal overhead when calculating the initial malloc maximum.
14660 Port --enable-checking=all to Fedora 14 x86.
14661 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14663 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14664 (overrun_check_realloc, overrun_check_free):
14665 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14666 That way, xmalloc returns a properly-aligned pointer even if
14667 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14668 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14669 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14670 into account when calculating the initial malloc maximum.
14671 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14672 Move here from alloc.c, so that charset.c can use it too.
14673 Properly align; the old code wasn't right for common 32-bit hosts
14674 when configured with --enable-checking=all.
14675 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14676 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14678 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14680 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14683 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14685 * xdisp.c (compute_display_string_end): If there's no display
14686 string at CHARPOS, return -1.
14688 * bidi.c (bidi_fetch_char): When compute_display_string_end
14689 returns a negative value, treat the character as a normal
14690 character not covered by a display string. (Bug#9624)
14692 2011-09-28 Juanma Barranquero <lekktu@gmail.com>

14696 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14698 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14699 newline, reseat the iterator instead of bidi-iterating there one
14700 character at a time. (Bug#9610)
14701 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14702 TO_CHARPOS if the bidi iterator is at base embedding level.
14704 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14706 * lread.c (readevalloop): Use correct code for NBSP.

14709 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14711 * dbusbind.c (Fdbus_register_signal): When service is not
14712 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14714 2011-09-25 Glenn Morris <rgm@gnu.org>
14716 * buffer.c (truncate-lines): Doc fix.
14718 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

14733 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14735 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14736 Default value is now t. Doc fix.
14738 * indent.c (Fvertical_motion): Compute and apply the overshoot
14739 logic when moving up, not only when moving down. Fix the
14740 confusing name and values of the it_overshoot_expected variable;
14741 logic changes accordingly. (Bug#9254) (Bug#9549)
14743 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14744 CHARPOS is covered by a display string which includes newlines.
14745 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14746 is covered by a display string with embedded newlines.
14748 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14750 * dbusbind.c (Fdbus_register_signal): Add match rule to
14751 Vdbus_registered_objects_table. (Bug#9581)
14752 (Fdbus_register_method, Vdbus_registered_objects_table):
14755 2011-09-24 Jim Meyering <meyering@redhat.com>
14757 do not ignore write error for any output size
14758 The previous change was incomplete.
14759 While it makes emacs --batch detect the vast majority of stdout
14760 write failures, errors were still ignored whenever the output size is
14761 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14762 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14763 && echo FAIL: ignored write error
14764 FAIL: ignored write error
14765 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14766 && echo FAIL: ignored write error
14767 FAIL: ignored write error
14768 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14770 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14772 * emacs.c (Fkill_emacs): In noninteractive mode exit
14773 non-successfully if a write error occurred on stdout. (Bug#9574)
14775 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14777 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14780 * dispextern.h (struct it): Update the comment documenting what
14783 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14785 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14786 a display string, extend search for cursor position to end of row.
14787 (find_row_edges): If the row ends in a newline from a display
14788 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14789 Handle the case of a display string with multiple newlines.
14790 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14791 non-empty line. Fixes confusing cursor motion with arrow keys at
14792 the beginning of a line that starts with whitespace.
14794 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14796 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14799 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14801 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14802 boolean (Bug#9154).
14804 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14806 * xdisp.c (display_line): Record maximum and minimum buffer
14807 positions even if no glyphs were produced (e.g., by a zero-width
14808 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14809 buffer positions that will be removed from the glyph row because
14811 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14812 column is beyond frame width: don't subtract 1 "pixel" when
14813 computing width of the stretch.
14814 (reseat_at_next_visible_line_start): Undo the change made on
14815 2011-09-17 that saved paragraph information and restored it after
14816 the call to `reseat'. (Bug#9545)
14818 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14820 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14821 and turn window cursor on if cleared (Bug#9415).
14823 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14825 * search.c (boyer_moore): Take unibyte characters from pattern
14826 literally. (Bug#9458)
14828 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14830 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14832 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14834 Fix minor problem found by static checking.

14836 initialized, to pacify gcc -Wuninitialized.
14838 * fileio.c: Report proper errno when syscall falls.
14839 (Finsert_file_contents): Save and restore errno,
14840 so that report_file_error outputs the correct diagnostic.
14841 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14843 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14845 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14847 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14849 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14850 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14852 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14854 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14855 about the current paragraph and restore it after the call to reseat.
14857 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14858 (bidi_find_paragraph_start): Search back for paragraph beginning
14859 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14860 (bidi_move_to_visually_next): Only trigger paragraph-related
14861 computations when the last character is a newline or at EOB, not
14862 just any NEUTRAL_B. (Bug#9470)
14864 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14865 truncated lines if point is covered by a display string. (Bug#9524)
14867 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14869 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14870 (cons_to_x_long): New function.
14871 (lisp_data_to_selection_data): Use it. Correct the test for
14872 short-versus-long data; it was negated. Break out of vector
14873 loop, for efficiency, when a long datum is discovered.
14875 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14877 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14879 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14881 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14882 GCC PR/17406) by declaring this function with external scope.
14884 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14886 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14887 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14889 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14891 * editfns.c (Fformat): Correctly handle text properties on "%%".

14900 (fill_composite_glyph_string): Add comments about special meaning
14901 of TAB characters in a composition.
14903 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14905 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14906 This occurs when processing a multibyte format.
14907 Problem reported by Wolfgang Jenker.
14909 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14911 * xdisp.c (try_cursor_movement): Only check for exact match if
14912 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14914 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14916 Remove unused external symbols.
14917 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14918 * xdisp.c (calc_pixel_width_or_height): Now static.
14919 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14920 * indent.c (check_display_width):
14921 * w32term.c: Fix comment to match code.
14922 * xterm.c, xterm.h (x_catching_errors): Remove.
14924 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14926 * xselect.c: Use signed conversions more consistently (Bug#9498).
14927 (selection_data_to_lisp_data): Assume incoming selection data are
14928 signed integers, not unsigned. This is to be consistent with
14929 outgoing selection data, which was modified to use signed integers
14930 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14931 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14932 expects long, not unsigned long.
14934 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14936 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14937 computation of loop end. Reported by Johan Bockgård
14940 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14942 * frame.c (Fother_visible_frames_p): Function deleted.
14944 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14946 * indent.c (compute_motion): Process display vector front to back
14947 rather than the other way around. (Bug#2496)
14949 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14951 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14953 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14955 * minibuf.c (Fread_from_minibuffer): Doc fix.
14957 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14959 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14960 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14962 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14964 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14965 value for non-existent files.
14967 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14969 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14970 set its "size" to -1. This will set the modtime_size field of
14971 the corresponding buffer to -1, which is what
14972 verify-visited-file-modtime expects for files that do not exist.
14975 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14977 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14979 * lisp.h: ... from here. push_key_description is no longer
14980 defined in keyboard.c, so its declaration should not be in
14981 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14982 logically belongs with push_key_description.
14984 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14986 * buffer.h: Include <sys/types.h> instead of <time.h>.
14987 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14988 Problem reported by Herbert J. Skuhra.
14990 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14992 * xml.c (parse_region): Make the parsing work for
14993 non-comment-starting XML files again (bug#9144).
14995 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14997 * image.c (gif_load): Fix calculation of bottom and right corner.
15000 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15002 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15003 redisplay in small windows.
15005 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15007 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15009 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15011 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15012 Operate on live windows only.
15014 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15016 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15018 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15020 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15021 only under bidi iteration.
15023 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15025 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15027 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15029 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15030 Without this fix, the command to link temacs failed due to an
15031 undefined symbol __builtin_isnan. This is because
15032 /usr/include/iso/math_c99.h #defines isnan(x) to
15033 __builtin_isnan(x), but the bundled gcc, which identifies itself
15034 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15036 * floatfns.c (isnan): #undef, and then #define to a clone of
15038 (Fisnan): Always define, since it's always available now.
15039 (syms_of_floatfns): Always define isnan at the Lisp level.
15041 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15043 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15045 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15047 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15048 The previous code assumed that file offsets (off_t values) fit in
15049 EMACS_INT variables, which is not true on typical 32-bit hosts.
15050 The code messed up by falsely reporting buffer overflow in cases
15051 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15052 when "big" contains more than 2**29 bytes, even though this
15053 inserts just one byte and does not overflow the buffer.
15054 (Finsert_file_contents): Store file offsets as off_t
15055 values, not as EMACS_INT values. Check for overflow when
15056 converting between EMACS_INT and off_t. When checking for
15057 buffer overflow or for overlap, take the offsets into account.
15058 Don't use EMACS_INT for small values where int suffices.
15059 When checking for overlap, fix a typo: ZV was used where
15060 ZV_BYTE was intended.
15061 (Fwrite_region): Don't assume off_t fits into 'long'.
15062 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15064 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15066 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15068 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15070 sprintf-related integer and memory overflow issues (Bug#9412).
15072 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15073 (esprintf, exprintf, evxprintf): New functions.
15074 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15075 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15076 (modify_event_symbol): Do not assume that the length of
15077 name_alist_or_stem is safe to alloca and fits in int.
15078 (Fexecute_extended_command): Likewise for function name and binding.
15079 (Frecursion_depth): Wrap around reliably on integer overflow.
15080 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15081 since some callers pass EMACS_INT values.
15082 (Fsingle_key_description): Don't crash if symbol name contains more
15083 than MAX_ALLOCA bytes.
15084 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15085 (get_minibuffer): Arg is now EMACS_INT, not int.
15086 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15087 (esprintf, exprintf, evxprintf): New decls.
15088 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15090 * dbusbind.c (signature_cat): New function.
15091 (xd_signature, Fdbus_register_signal):
15092 Do not overrun buffer; instead, report string overflow.
15094 * dispnew.c (add_window_display_history): Don't overrun buffer.
15095 Truncate instead; this is OK since it's just a log.
15097 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15098 even if the time zone offset is outlandishly large.
15099 Don't mishandle offset == INT_MIN.
15101 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15102 when creating daemon; the previous buffer-overflow check was incorrect.
15104 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15105 which has the guts of the old verror function.
15107 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15108 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15110 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15111 (font_unparse_xlfd): Don't blindly alloca long strings.
15112 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15113 fits in int, when using sprintf. Use single snprintf to count
15114 length of string rather than counting it via multiple sprintfs;
15115 that's simpler and more reliable.
15116 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15117 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15118 sprintf, in case result does not fit in int.
15120 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15121 (fontset_from_font): Print it.
15123 * frame.c (tty_frame_count): Now printmax_t, not int.
15124 (make_terminal_frame, set_term_frame_name): Print it.
15125 (x_report_frame_params): In X, window IDs are unsigned long,
15126 not signed long, so print them as unsigned.
15127 (validate_x_resource_name): Check for implausibly long names,
15128 and don't assume name length fits in 'int'.
15129 (x_get_resource_string): Don't blindly alloca invocation name;
15130 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15133 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15134 (xg_check_special_colors, xg_set_geometry):
15135 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15137 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15138 Use esprintf, not sprintf, in case result does not fit in int.
15140 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15141 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15142 it as a large positive number.
15143 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15144 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15146 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15147 in case result does not fit in int.
15149 * print.c (float_to_string): Detect width overflow more reliably.
15150 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15151 buffer overrun. Don't assume list length fits in 'int'. Treat
15152 print length of 0 as 0, not as infinity; to be consistent with other
15153 uses of print length in this function. Don't overflow print length
15154 index. Don't assume hash table size fits in 'long', or that
15155 vectorlike size fits in 'unsigned long'.
15157 * process.c (make_process): Use printmax_t, not int, to format
15158 process-name gensyms.
15160 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15162 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15163 to avoid potential buffer overrun.
15165 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15166 if X resource line is longer than 512 bytes.
15168 * xfns.c (x_window): Make sprintf buffer a bit bigger
15169 to avoid potential buffer overrun.
15171 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15173 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15175 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15177 Integer overflow fixes for scrolling, etc.
15178 Without these, Emacs silently mishandles large integers sometimes.
15179 For example, "C-u 4294967297 M-x recenter" was treated as if
15180 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15182 * xdisp.c (try_window_id): Check Emacs fixnum range before
15183 converting to 'int'.
15185 * window.c (window_scroll_line_based, Frecenter):
15186 Check that an Emacs fixnum is in range before assigning it to 'int'.
15187 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15188 values converted from Emacs fixnums.
15189 (Frecenter): Don't wrap around a line count if it is out of 'int'
15190 range; instead, treat it as an extreme value.
15191 (Fset_window_configuration, compare_window_configurations):
15192 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15194 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15195 that can exceed INT_MAX. Check that EMACS_INT value is in range
15196 before assigning it to the (possibly-narrower) index.
15197 (match_limit): Don't assume that a fixnum can fit in 'int'.
15199 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15202 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15203 (Fvertical_motion): Don't wrap around LINES values that don't fit
15204 in 'int'. Instead, treat them as extreme values. This is good
15205 enough for windows, which can't have more than INT_MAX lines anyway.
15207 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15209 * Require libxml/parser.h to avoid compilation warning.
15211 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15213 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15214 since this reportedly can destroy thread storage.
15216 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15218 * syntax.c (find_defun_start): Update all cache variables if
15219 exiting early (Bug#9401).
15221 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15223 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15225 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15226 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15227 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15229 * term.c (tty_append_glyph): New function.
15230 (produce_stretch_glyph): Static function and its prototype deleted.
15232 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15235 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15237 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15238 when checking :margin (Bug#9390).
15239 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15240 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15241 so that the name doesn't mislead. All uses changed.
15243 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15245 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15248 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15250 * xdisp.c (move_it_to): Don't bail out early when reaching
15251 position beyond to_charpos, if we are scanning backwards.
15252 (move_it_vertically_backward): When DY == 0, make sure we get to
15253 the first character in the line after the newline.
15255 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15257 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15258 (ccl_driver): Do not generate an out-of-range pointer.
15259 (Fccl_execute_on_string): Remove unnecessary check for
15260 integer overflow, noted by Stefan Monnier in
15261 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15262 Remove a FIXME that didn't need fixing.
15263 Simplify the newly-introduced buffer reallocation code.
15265 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15267 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15269 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15271 Integer and memory overflow issues (Bug#9196).
15273 * doc.c (get_doc_string): Rework so that
15274 get_doc_string_buffer_size is the actual buffer size, rather than
15275 being 1 less than the actual buffer size; this makes xpalloc more
15278 * image.c (x_allocate_bitmap_record, cache_image):
15279 * xselect.c (Fx_register_dnd_atom):
15280 Simplify previous changes by using xpalloc.
15282 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15283 since either will do and ptrdiff_t is convenient with xpalloc.
15285 * charset.c (charset_table_size)
15286 (struct charset_sort_data.priority): Now ptrdiff_t.
15287 (charset_compare): Don't overflow if priorities differ greatly.
15288 (Fsort_charsets): Don't assume list length fits in int.
15289 Check for size-calculation overflow when allocating sort data.
15290 (syms_of_charset): Allocate an initial charset table that is
15291 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15293 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15295 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15296 The actual value is always <= INT_MAX, and leaving it unsigned made
15297 overflow checking harder.
15299 * dispextern.h (struct glyph_matrix.rows_allocated)
15300 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15301 with xpalloc. The values are still always <= INT_MAX.
15303 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15305 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15306 (SAFE_NALLOCA): New macro.
15308 * region-cache.c (struct boundary.pos, find_cache_boundary)
15309 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15310 (set_cache_region, invalidate_region_cache)
15311 (revalidate_region_cache, know_region_cache, region_cache_forward)
15312 (region_cache_backward, pp_cache):
15313 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15314 so that ptrdiff_t * can be passed to xpalloc.
15315 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15316 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15317 (pp_cache): Don't assume cache_len fits in int.
15318 * region-cache.h: Adjust extern decls to match.
15320 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15321 EMACS_INT, since either will do, for xpalloc.
15323 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15324 (xnmalloc, xnrealloc, xpalloc): New functions.
15326 * bidi.c (bidi_shelve_header_size): New constant.
15327 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15328 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15330 * bidi.c (bidi_cache_shrink):
15331 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15333 Don't update size of array until after memory allocation succeeds,
15334 because xmalloc/xrealloc may not return.
15335 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15336 now that we have proper integer overflow checking.
15337 (record_overlay_string, overlay_strings): Catch overflows when
15338 calculating size of overlay_str_buf.
15340 * callproc.c (Fcall_process): Check for size overflow when
15341 calculating size of args2.
15342 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15343 Normally we prefer signed values, but sticking with ptrdiff_t would
15344 require adding more-complicated checks.
15346 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15347 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15348 Redo buffer-overflow calculations to avoid integer overflow.
15349 Add a FIXME comment where memory seems to be over-allocated.
15351 * character.c (Fstring): Check for size-calculation overflow.
15353 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15354 unnecessary integer overflow. Check for size overflow.
15355 (encode_coding_object): Don't update size until xmalloc succeeds.
15357 * composite.c (get_composition_id): Check for overflow in glyph
15358 length calculations.
15360 Integer and memory overflow fixes for display code.
15361 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15362 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15363 (scrolling_window): Check for overflow in size calculations.

15367 (row_table_size): Now ptrdiff_t, not int.
15368 (scrolling_window): Avoid overflow in size calculations.
15369 Don't update size until allocation succeeds.
15370 * fns.c (concat): Check for overflow in size calculations.
15371 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15372 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15375 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15376 (get_doc_string): Check for size calculation overflow.
15377 Don't update size until allocation succeeds.
15378 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15379 EMACS_INT, where ptrdiff_t will do.
15380 (Fsubstitute_command_keys): Check for string overflow.
15382 * editfns.c (set_time_zone_rule): Don't assume environment length
15384 (message_length): Now ptrdiff_t, not int.
15385 (Fmessage_box): Don't update size until allocation succeeds.
15386 Don't assume message length fits in int.
15387 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15389 * emacs.c (main): Do not reallocate argv, since there is a null at
15390 the end that can be overwritten, and this way there's no need to
15391 worry about size-calculation overflow.
15392 (sort_args): Check for size-calculation overflow.
15394 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15396 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15398 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15399 (x_set_scroll_bar_width, x_figure_window_size):
15400 Check for integer overflow.
15401 (x_set_alpha): Do not assume XINT fits in int.
15403 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15404 This is for the members text_lines, text_cols, total_lines, total_cols,
15405 where the system imposes an 'int' limit.
15407 * fringe.c (Fdefine_fringe_bitmap):
15408 Don't update size until alloc works.
15410 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15411 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15413 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15414 Check for size-calculation overflow.
15415 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15416 do, as we prefer signed integers.
15417 (id_to_widget.max_size, id_to_widget.used)
15418 (xg_store_widget_in_map, xg_remove_widget_from_map)
15419 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15420 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15421 Use and return ptrdiff_t, not int.
15422 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15423 * gtkutil.h: Change prototypes to match the above.
15425 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15426 are duplicate now that they've been promoted to lisp.h.
15427 (x_allocate_bitmap_record, x_alloc_image_color)
15428 (make_image_cache, cache_image, xpm_load):
15429 Don't update size until alloc is done.
15430 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15432 Check for size calculation overflow.
15433 (ct_colors_allocated_max): New constant.
15434 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15437 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15438 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15439 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15440 Use ptrdiff_t, not int, to count maps.
15441 (read_char_minibuf_menu_prompt): Check for overflow in size
15442 calculations. Don't update size until allocation succeeds.
15443 Redo calculations to avoid overflow.
15444 * keyboard.h: Change prototypes to match the above.
15446 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15448 (current_minor_maps): Check for size calculation overflow.
15449 * keymap.h: Change prototypes to match the above.
15451 * lread.c (read1, init_obarray): Don't update size until alloc done.
15453 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15454 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15456 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15457 Now ptrdiff_t, not int.
15458 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15464 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15466 * scroll.c (do_line_insertion_deletion_costs): Check for size calc

15470 (Fset_match_data): Don't assume list lengths fit in 'int'.
15472 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15473 for command line length. Do not attempt to address one before the
15474 beginning of an array, as that's not portable.
15476 * term.c (max_frame_lines): Remove; unused.
15477 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15479 (encode_terminal_code, calculate_costs): Check for size
15480 calculation overflow.

15483 done. Redo calculations to avoid overflow.
15484 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15486 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15487 subtracting pointers.
15488 (gobble_line): Check for overflow more carefully. Don't update size
15491 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

15502 Use ptrdiff_t, not int, for sizes.
15503 (Finternal_make_lisp_face, cache_face):
15504 Check for size calculation overflow.
15505 (cache_face): Treat size calculation overflows as if they were
15506 memory exhaustion (the usual treatment), rather than aborting.
15508 * xfns.c (x_encode_text, x_set_name_internal)
15509 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15510 sizes, since they can exceed INT_MAX in size. Check for size
15511 calculation overflow.
15513 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15514 (xg_select): Check for size calculation overflow.
15515 Don't update size until alloc done.
15517 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15518 as sprintf is limited to int lengths.
15520 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15521 (X_LONG_MIN): New macros.
15522 Use them to make the following changes clearer.
15523 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15524 This change doesn't affect the value now, but it may help remind
15525 future maintainers not to raise the value too much later.
15526 (SELECTION_QUANTUM): Remove, replacing with ...
15527 (selection_quantum): ... new function, which avoids overflow.
15529 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15530 assumption that selection length fits in 'int'.
15531 (x_reply_selection_request, x_handle_selection_request)
15532 (x_get_window_property, receive_incremental_selection)
15533 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15534 (lisp_data_to_selection_data, clean_local_selection_data):

15536 (x_reply_selection_request, x_get_window_property)
15537 (receive_incremental_selection, x_property_data_to_lisp):
15538 Redo calculations to avoid overflow.
15539 (x_reply_selection_request): When sending hint, ceiling it at
15540 X_LONG_MAX rather than relying on wraparound overflow to send
15542 (x_get_window_property, receive_incremental_selection)
15543 (lisp_data_to_selection_data, x_property_data_to_lisp):
15544 Check for size-calculation overflow.
15545 (x_get_window_property, receive_incremental_selection)
15546 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15547 Don't store size until memory allocation succeeds.
15548 (x_get_window_property): Plug memory leak on memory exhaustion.
15549 Don't double-block input; malloc is safe here. Don't assume 2**34
15550 - 4 fits in unsigned long. Add an xassert to check
15551 XGetWindowProperty overflow. Be more careful about overflow
15552 calculations, and distinguish size from memory overflow better.
15553 (receive_incremental_selection): When tracing, don't assume
15554 unsigned int is less than INT_MAX.
15555 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15556 harmful) conversions of unsigned short to int.
15557 (lisp_data_to_selection_data): Don't assume that integers
15558 in the range -65535 through -1 fit in an X unsigned short.
15559 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15560 result parameters unless successful. Rely on cons_to_unsigned
15561 to report problems with elements; the old code wasn't right anyway.
15562 (x_check_property_data): Check for int overflow; we cannot use
15563 a wider type due to X limits.
15564 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15566 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15596 * lisp.h (hash_lookup, hash_put):
15597 * minibuf.c (Ftest_completion):
15598 Use ptrdiff_t for hash table indexes, not int (which is too
15599 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15600 32-bit --with-wide-int hosts).
15602 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15603 Add a FIXME comment about memory leaks.
15604 (syms_of_charset): Don't assume xmalloc returns.
15606 Don't assume that stated character widths fit in int.
15607 * character.c (Fchar_width, c_string_width, lisp_string_width):
15608 * character.h (CHAR_WIDTH):
15609 * indent.c (MULTIBYTE_BYTES_WIDTH):
15610 Use sanitize_char_width to avoid undefined and/or bad behavior
15611 with outlandish widths.
15612 * character.h (sanitize_tab_width): Rename from sanitize_width,
15613 now that we have two such functions. All uses changed.
15614 (sanitize_char_width): New inline function.
15616 Don't assume that tab-width fits in int.
15617 * character.h (sanitize_width): New inline function.
15618 (SANE_TAB_WIDTH): New macro.
15619 (ASCII_CHAR_WIDTH): Use it.

15624 * fileio.c: Integer overflow issues with file modes.
15625 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15627 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15628 Remove unreachable code.
15629 (read_hex, load_charset_map_from_file): Check for integer overflow.
15631 * xterm.c: Don't go over XClientMessageEvent limit.
15632 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15633 (x_send_scroll_bar_event): Likewise. Check that the size does not
15634 exceed limits imposed by XClientMessageEvent, as well as the usual
15635 ptrdiff_t and size_t limits.
15637 * keyboard.c: Overflow, signedness and related fixes.
15638 (make_lispy_movement): Use same integer type in forward decl
15639 that is used in the definition.
15640 (read_key_sequence, keyremap_step):
15641 Change bufsize argument back to int, undoing my 2011-03-30 change.
15642 We prefer signed types, and int is wide enough here.
15643 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15644 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15645 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15646 length, not size_t. Use ptrdiff_t for index, not int.
15647 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15648 possibility of integer overflow.
15650 Overflow, signedness and related fixes for images.
15652 * dispextern.h (struct it.stack[0].u.image.image_id)
15653 (struct_it.image_id, struct image.id, struct image_cache.size)

15660 * xdisp.c (calc_pixel_width_or_height):
15661 * xfns.c (image_cache_refcount):
15662 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
15663 on typical 64-bit hosts.

15669 when the callers expect that.
15670 (image_ascent): Redo ascent calculation to avoid int overflow.
15671 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15672 (lookup_image): Remove unnecessary tests.
15673 (xbm_image_p): Locals are now of int, not EMACS_INT,
15674 since parse_image_check makes sure they fit into int.
15675 (png_load, gif_load, svg_load_image):
15676 Prefer int to unsigned where either will do.
15677 (tiff_handler): New function, combining the cores of the
15678 old tiff_error_handler and tiff_warning_handler.
15679 This function is rewritten to use vsnprintf and thereby avoid
15680 stack buffer overflows. It uses only the features of vsnprintf
15681 that are common to both POSIX and native Microsoft.
15682 (tiff_error_handler, tiff_warning_handler): Use it.
15683 (tiff_load, gif_load, imagemagick_load_image):
15684 Don't assume :index value fits in 'int'.
15685 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15686 (imagemagick_load_image): Check that crop parameters fit into
15687 the integer types that MagickCropImage accepts. Don't assume
15688 Vimagemagick_render_type has a nonnegative value. Don't assume
15689 size_t fits in 'long'.
15690 (gs_load): Use printmax_t to print the widest integers possible.
15691 Check for integer overflow when computing image height and width.

15700 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15701 the display spec is of the form `(space ...)'.
15702 (handle_display_spec): Return the value returned by
15703 handle_single_display_spec, not just 1 or zero.
15704 (handle_single_display_spec): If the display spec is of the form
15705 `(space ...)', and specifies display in the text area, return 2
15707 (try_cursor_movement): Check for the need to scroll more
15708 accurately, and prefer exact match for point under bidi.
15709 Don't advance `row' beyond the last row of the window.
15711 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15712 into disp_prop; all users changed.
15714 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15715 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15716 for the text covered by the display property.

15726 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15727 buffers, return left-to-right.
15728 (set_cursor_from_row): Consider candidate row a win if its glyph
15729 represents a newline and point is on that newline. Fixes cursor
15730 positioning on the newline at EOL of R2L text within L2R
15731 paragraph, and vice versa.
15732 (try_cursor_movement): Check continued rows, in addition to
15733 continuation rows. Fixes unwarranted scroll when point enters a
15734 continued line of R2L text within an L2R paragraph, or vice versa.
15735 (cursor_row_p): Consider the case of point being equal to
15736 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15737 from the end of a short line to the beginning of a continued line
15738 of R2L text within L2R paragraph.
15739 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15740 composed characters.
15742 * bidi.c (bidi_check_type): Use xassert.

15755 2011-08-22 Kenichi Handa <handa@m17n.org>
15757 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15758 extra slot even if the purpose is char-code-property-table.
15760 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15762 * xdisp.c (redisplay_window): When computing centering_position,
15763 account for the height of the header line. (Bug#8874)
15765 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15766 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15767 candidate is selected by the mouse, and that candidate has a
15768 composed character under the mouse.
15770 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15771 coordinates reported by pos-visible-in-window-p for a composed
15772 character in column zero.
15774 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15776 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15778 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15780 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15781 consider it a hit if to_charpos is anywhere in the range of the
15782 composed buffer positions.
15784 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15786 * image.c (gif_load): Don't assume that each subimage has the same
15787 dimensions as the base image. Handle disposal method that is
15788 "undefined" by the gif spec (Bug#9335).
15790 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15792 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15795 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15797 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15798 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15799 from an Org mode buffer to a Speedbar frame.
15801 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15802 a composition, take its buffer position from IT->cmp_it.charpos.
15803 Fixes cursor positioning at the beginning of a line that begins
15804 with a composed character.
15806 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15808 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15809 character bidirectional type, use STRONG_L instead. Fixes crashes
15810 in a buffer produced by `describe-categories'.
15812 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15813 members before the level stack, so they would be saved and
15814 restored when copying iterator state. Fixes incorrect reordering
15815 around TABs covered by display properties.
15817 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15819 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15825 Remove unnecessary aborts (Bug#9081).
15827 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15829 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15830 has no `load' handler, try opening the file locally. (Bug#9311)
15832 2011-08-16 Ken Brown <kbrown@cornell.edu>
15834 * gmalloc.c: Expand comment.
15836 2011-08-16 Eli Zaretskii <eliz@gnu.org>
15838 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15839 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

15885 after the pid of the process is set to -1 (Bug#8162).
15887 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15889 * xdisp.c (move_it_in_display_line_to): Don't invoke
15890 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15891 ppos_it. Fixes vertical cursor motion when line beginning is
15892 covered by an image. (Bug#9296)
15894 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15896 * nsterm.h (ns_run_ascript): Declare.

15900 (ns_run_ascript): New function.
15901 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15902 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15903 the event loop. Get status from as_status (Bug#7276).
15905 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15906 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15907 the event loop (Bug#7276).
15909 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15932 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15933 (Fnetwork_interface_list): Allocate in increments of bytes instead
15934 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15935 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15937 (struct ifflag_def): notrailers is smart on OSX.
15938 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15939 Get hardware address with getifaddrs if available.
15941 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15943 * xdisp.c (iterate_out_of_display_property): xassert that
15944 IT->position is set to within IT->object's boundaries. Break from
15945 the loop as soon as EOB is reached; avoids infloops in redisplay
15946 when IT->position is set up wrongly due to some bug.
15947 Set IT->current to match the bidi iterator unconditionally.
15948 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15949 entry. Force push_it to save on the stack the current
15950 buffer/string position, to be restored by pop_it. Fix flags in
15951 the iterator structure wrt the object coming from a display
15952 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15953 properties. (Bug#9284)
15955 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15957 * fontset.c (fontset_get_font_group): Add proper type checks.

15970 no-display-properties-and-no-overlays under bidi display.
15971 Set disp_pos in the bidi iterator to avoid searches for display
15972 properties and overlays.
15974 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15976 * editfns.c (Fset_time_zone_rule): Document relationship with the

15982 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15984 * composite.c (autocmp_chars): Don't reset point. That is done by
15985 restore_point_unwind (Bug#5984).
15987 2011-08-07 Juri Linkov <juri@jurta.org>
15989 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15990 to show the arg `TIME' instead of `TIMEVAL'.
15992 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15994 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15995 display property strides EOL and includes a newline, as in
15996 longlines-mode. (Bug#9254)
15997 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15998 word-wrap under bidirectional display. (Bug#9224)
16000 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16001 is non-zero, even if the data buffer is NULL. Fixes a crash in
16002 vertical-motion with longlines-mode. (Bug#9254)
16004 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16006 * bidi.c <bidi_cache_total_alloc>: Now static.

16009 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16012 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16013 amount allocated this far in `bidi_cache_total_alloc'.
16014 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16015 non-zero, only free the data buffer without restoring the cache
16016 contents. All callers changed.
16018 * dispextern.h (bidi_unshelve_cache): Update prototype.
16020 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16021 (move_it_in_display_line, move_it_to)
16022 (move_it_vertically_backward, move_it_by_lines): Replace the call
16023 to xfree to an equivalent call to bidi_unshelve_cache.
16024 (move_it_in_display_line_to): Fix logic of returning
16025 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16027 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16029 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16030 came from a string character with a `cursor' property. (Bug#9229)
16032 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16034 * Makefile.in (LIB_PTHREAD): New variable.

16047 (x_set_frame_alpha): Find topmost parent window with
16048 x_find_topmost_parent and set the property there also (bug#9181).
16049 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16051 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16053 * callproc.c (Fcall_process): Avoid vfork clobbering
16054 the local vars buffer, coding_systems, current_dir.
16056 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16058 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16060 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16062 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16063 so that it is not optimized away.
16065 * xdisp.c (compute_display_string_pos): Remove unused local.
16067 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16069 Fix slow cursor motion and scrolling in large buffers with
16070 selective display, like Org Mode buffers. (Bug#9218)
16072 * dispextern.h (struct bidi_it): New member disp_prop_p.
16074 * xdisp.c: Remove one-slot cache of display string positions.
16075 (compute_display_string_pos): Accept an additional argument
16076 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16077 for a display string or property. If found, set DISP_PROP_P
16080 * bidi.c (bidi_fetch_char): Accept an additional argument
16081 DISP_PROP_P, and pass it to compute_display_string_pos.
16082 Only handle text covered by a display string if DISP_PROP_P is returned
16083 non-zero. All callers of bidi_fetch_char changed.
16085 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16087 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16089 2010-12-03 Don March <don@ohspite.net>
16091 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16092 last character M-[char] is translated to ESC [char] (bug#7541).
16094 2011-08-02 Kenichi Handa <handa@m17n.org>
16096 * lisp.h (uniprop_table): Extern it.
16098 * chartab.c (uniprop_table): Make it non-static.
16100 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16102 * xdisp.c (forward_to_next_line_start): Accept additional argument
16103 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16105 (reseat_at_next_visible_line_start): Use the bidi iterator state
16106 returned by forward_to_next_line_start to restore the state of
16107 it->bidi_it after backing up to previous newline. (Bug#9212)
16109 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16111 * regex.c (re_comp): Protoize.
16112 (re_exec): Fix return type.
16113 (regexec): Fix type of `ret'. (Bug#9203)
16115 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16117 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16118 This is needed if max-image-size is a floating-point number.
16120 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16122 * print.c (print_object): Print empty symbol as ##.
16124 * lread.c (read1): Read ## as empty symbol.
16126 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16128 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16129 setting frame foreground color (Bug#9175).
16130 (x_set_background_color): Likewise.
16132 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16133 contents (Bug#9176).
16134 (EmacsTooltip -init): Remove bezels and add shadows to
16137 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16138 or scroll bar (Bug#8470).
16140 * nsfont.m (nsfont_open): Remove assignment to voffset and
16141 unnecessary vars hshink, expand, hd, full_height, min_height.
16142 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16144 * nsterm.h (nsfont_info): Remove voffset field.
16146 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16148 Implement strike-through and overline on NextStep (Bug#8863).
16150 * nsfont.m (nsfont_open): Use underline position provided by font,
16151 instead of hard-coded value of 2.
16152 (nsfont_draw): Call ns_draw_text_decoration instead.
16154 * nsterm.h: Add declaration for ns_draw_text_decoration.
16156 * nsterm.m (ns_draw_text_decoration): New function for drawing
16157 underline, overline, and strike-through.
16158 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16159 ns_draw_text_decoration. Change treatment of cursor drawing to
16160 accommodate underlining, etc.
16162 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16164 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16167 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16169 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16170 Without this fix, if a signal arrives just after memory fills up,
16171 'malloc' might be invoked reentrantly.
16173 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16174 In other words, assume that every image size is allowed, on non-X
16175 hosts. This assumption is probably wrong, but it lets Emacs compile.
16177 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16179 * regex.c (re_iswctype): Convert return values to boolean.
16181 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16183 * xdisp.c (compute_display_string_pos): Don't use cached display
16184 string position if the buffer had its restriction changed.
16187 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16189 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16191 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16193 Integer signedness and overflow and related fixes. (Bug#9079)
16195 * bidi.c: Integer size and overflow fixes.
16196 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16197 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16198 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16199 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16200 (bidi_find_other_level_edge):
16201 Use ptrdiff_t instead of EMACS_INT where either will do.
16202 This works better on 32-bit hosts configured --with-wide-int.
16203 (bidi_cache_ensure_space): Check for size-calculation overflow.
16204 Use % rather than repeated addition, for better worst-case speed.
16205 Don't set bidi_cache_size until after xrealloc returns, because it
16207 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16208 (bidi_cache_ensure_space): Also check that the bidi cache size
16209 does not exceed that of the largest Lisp string or buffer. See Eli
16210 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16212 * alloc.c (__malloc_size_t): Remove.
16213 All uses replaced by size_t. See Andreas Schwab's note
16214 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16216 * image.c: Improve checking for integer overflow.
16217 (check_image_size): Assume that f is nonnull, since
16218 it is always nonnull in practice. This is one less thing to
16219 worry about when checking for integer overflow later.
16220 (x_check_image_size): New function, which checks for integer
16221 overflow issues inside X.
16222 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16223 This removes the need for a memory_full check.
16224 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16225 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16226 (xbm_read_bitmap_data): Change locals back to 'int', since
16227 their values must fit in 'int'.
16228 (xpm_load_image, png_load, tiff_load):
16229 Invoke x_create_x_image_and_pixmap earlier,
16230 to avoid much needless work if the image is too large.
16231 (tiff_load): Treat overly large images as if
16232 x_create_x_image_and_pixmap failed, not as malloc failures.
16233 (gs_load): Use x_check_image_size.
16235 * gtkutil.c: Omit integer casts.
16236 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16237 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16239 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16241 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16242 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16243 would wrongly return t on a 64-bit host.
16245 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16246 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16247 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16248 and therefore cause GCC to emit a bogus diagnostic in some cases.
16250 * image.c: Integer signedness and overflow and related fixes.
16251 This is not an exhaustive set of fixes, but it's time to
16252 record what I've got.
16253 (lookup_pixel_color, check_image_size): Remove redundant decls.
16254 (check_image_size): Don't assume that arbitrary EMACS_INT values
16255 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16256 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16257 (tiff_load, imagemagick_load_image):
16258 Check for overflow in size calculations.
16259 (x_create_x_image_and_pixmap): Remove unnecessary test for
16260 xmalloc returning NULL; that can't happen.
16261 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16262 (xpm_color_bucket): Use better integer hashing function.
16263 (xpm_cache_color): Don't possibly over-allocate memory.
16264 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16265 (gif_memory_source):
16266 Use ptrdiff_t, not int or size_t, to record sizes.
16267 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16268 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16269 either works, as we prefer signed integers.
16270 (tiff_read_from_memory, tiff_write_from_memory):
16271 Return tsize_t, not size_t, since that's what the TIFF API wants.
16272 (tiff_read_from_memory): Don't fail simply because the read would
16273 go past EOF; instead, return a short read.
16274 (tiff_load): Omit no-longer-needed casts.
16275 (Fimagemagick_types): Don't assume size fits into 'int'.
16277 Improve hashing quality when configured --with-wide-int.
16278 * fns.c (hash_string): New function, taken from sxhash_string.
16279 Do not discard information about ASCII character case; this
16280 discarding is no longer needed.
16281 (sxhash-string): Use it. Change sig to match it. Caller changed.
16282 * lisp.h: Declare it.
16283 * lread.c (hash_string): Remove, since we now use fns.c's version.
16284 The fns.c version returns a wider integer if --with-wide-int is
16285 specified, so this should help the quality of the hashing a bit.
16287 * emacs.c: Integer overflow minor fix.
16288 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16289 Define only if GNU_LINUX.
16290 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16292 * dispnew.c: Integer signedness and overflow fixes.
16293 Remove unnecessary forward decls, that were a maintenance hassle.
16294 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16296 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16297 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16298 (prepare_desired_row, line_draw_cost):
16299 Use int, not unsigned, where either works.
16300 (save_current_matrix, restore_current_matrix):
16301 Use ptrdiff_t, not size_t, where either works.
16302 (init_display): Check for overflow more accurately, and without
16303 relying on undefined behavior.
16305 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16306 Remove, replacing with the new symbols in lisp.h. All uses changed.
16307 * fileio.c (make_temp_name):
16308 * filelock.c (lock_file_1, lock_file):
16309 * xdisp.c (message_dolog):
16310 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16311 Use pMd etc. instead.
16312 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16313 replacing the pWIDE etc. symbols removed from editfns.c.
16315 * keyboard.h (num_input_events): Now uintmax_t.
16316 This is (very slightly) less likely to mess up due to wraparound.
16319 * buffer.c: Integer signedness fixes.
16320 (alloc_buffer_text, enlarge_buffer_text):
16321 Use ptrdiff_t rather than size_t when either will do, as we prefer
16324 * alloc.c: Integer signedness and overflow fixes.
16325 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16326 (__malloc_size_t): Default to size_t, not to int.
16327 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16328 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16329 Prefer ptrdiff_t to size_t when either would do, as we prefer
16331 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16332 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16333 Now const. Initialize with values that are in range even if char
16335 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16336 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16337 These functions do the right thing with sizes > 2**32.
16338 (check_depth): Now ptrdiff_t, not int.
16339 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16340 Adjust to new way of storing sizes. Check for size overflow bugs
16342 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16343 slightly wrong anyway, as it missed one instance of
16344 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16345 (refill_memory_reserve): Omit needless cast to size_t.
16346 (mark_object_loop_halt): Mark as externally visible.
16348 * xselect.c: Integer signedness and overflow fixes.
16349 (Fx_register_dnd_atom, x_handle_dnd_message):
16350 Use ptrdiff_t, not size_t, since we prefer signed.
16351 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16352 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16353 x_dnd_atoms_size and x_dnd_atoms_length.
16355 * doprnt.c: Prefer signed to unsigned when either works.
16357 * doprnt.c (doprnt):
16359 * xdisp.c (vmessage):
16360 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16361 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16362 prefer signed arithmetic to avoid comparison confusion.
16363 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16364 but is a bit tricky.
16366 Assume freestanding C89 headers, string.h, stdlib.h.
16367 * data.c, doprnt.c, floatfns.c, print.c:
16368 Include float.h unconditionally.
16369 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16370 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16371 * regex.c: Likewise for stddef.h, string.h.
16372 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16373 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16374 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16375 (STDC_HEADERS): Remove obsolete defines.
16376 * sysdep.c: Include limits.h unconditionally.
16378 Assume support for memcmp, memcpy, memmove, memset.
16379 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16380 * regex.c (memcmp, memcpy):
16381 Remove; we assume C89 now.
16383 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16384 (__malloc_safe_bcopy): Remove; no longer needed.
16386 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16387 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16388 well either way, and we prefer signed to unsigned.
16390 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16392 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16393 closes the connection while we're reading (bug#9182).
16395 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16397 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16398 are specified (Bug#9168).
16400 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16402 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16403 Found by GCC static checking and --with-wide-int on a 32-bit host.
16405 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16407 * xdisp.c (compute_display_string_pos): Fix logic of caching
16408 previous display string position. Initialize cached_prev_pos to
16409 -1. Fixes slow-down at the beginning of a buffer.
16411 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16413 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16414 for attrs[LFACE_FONTSET_INDEX].
16416 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16418 * xml.c (parse_region): Remove unused local
16419 that was recently introduced.
16421 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16423 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16424 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16426 * xdisp.c (move_it_in_display_line_to): Record the best matching
16427 position for TO_CHARPOS while scanning the line, and restore it on
16428 exit if none of the characters scanned was an exact match.
16429 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16430 when exact match is impossible due to invisible text, and the
16431 lines are truncated.
16433 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16435 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16438 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16440 Fix a significant slow-down of cursor motion with C-n, C-p,
16441 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16442 auto-repeat under bidi redisplay in fontified buffers.
16443 * xdisp.c (compute_stop_pos_backwards): New function.
16444 (next_element_from_buffer): Call compute_stop_pos_backwards to
16445 find a suitable prev_stop when we find ourselves before
16447 (reseat): Don't look for prev_stop, as that could mean a very long
16449 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16450 <cached_disp_overlay_modiff>: Cache for last found display string
16452 (compute_display_string_pos): Return the cached position if asked
16453 about the same buffer in the same area of character positions, and
16454 the buffer wasn't changed since the time the display string
16455 position was cached.
16457 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16459 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16460 is an integer, which is important for empty lines. (Bug#9149)
16462 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16464 * frame.c (Fmodify_frame_parameters): In tty case, update the
16465 default face if necessary (Bug#4238).
16467 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16469 * editfns.c (Fstring_to_char): No need to explain what a character
16470 is in the docstring (Bug#6576).
16472 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16474 * xml.c (parse_region): Make sure we always return a tree.
16476 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16478 * xml.c (parse_region): If a document contains only comments,
16481 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16483 * xml.c (make_dom): Return comments, too.
16485 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16488 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16489 and the surrounding thread.
16490 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16491 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16492 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16494 * s/openbsd.h (BROKEN_SIGIO): Define.
16495 * unexelf.c (unexec) [__OpenBSD__]:
16496 Don't update the .mdebug section of the Alpha COFF symbol table.
16498 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16500 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16503 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16505 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16506 This fixes some race conditions on the permissions of any newly
16509 * alloc.c (valid_pointer_p): Use pipe, not open.
16510 This fixes some permissions issues when debugging.
16512 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16513 If fchown fails to set both uid and gid, try to set just gid,
16514 as that is sometimes allowed. Adjust the file's mode to eliminate
16515 setuid or setgid bits that are inappropriate if fchown fails.
16517 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16519 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16525 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16527 * lread.c (read_integer): Unread even EOF character.
16528 (read1): Likewise. Properly record start position of symbol.

16531 symbol character follows.
16533 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16535 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16536 This works around a problem with the previous change to Fcopy_file.
16537 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16538 and without this change, GCC might complain about discarding
16539 fchown's return value.
16541 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16543 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16545 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16547 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16549 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16551 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16552 it's used from the C level.
16554 * process.c: Use the same condition for POLL_FOR_INPUT in both
16555 keyboard.c and process.c (bug#1858).
16557 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16559 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16560 (Fgnutls_boot): Use it.
16562 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16564 * doc.c (Fsubstitute_command_keys): Revert last change.
16566 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16568 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16569 quotes the next character, and doesn't affect other longer
16570 sequences (bug#8935).
16572 * lread.c (syms_of_lread): Clarify that is isn't only
16573 `eval-buffer' and `eval-defun' that's affected by
16574 `lexical-binding' (bug#8460).
16576 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16578 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16579 bidi redisplay when a line includes both an image and is truncated.
16581 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16583 Fix minor problems found by static checking.
16584 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16585 (elsz): Now a signed constant, not a size_t var. We prefer signed
16586 types to unsigned, to avoid integer comparison confusion. Without
16587 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16588 "cannot optimize loop, the loop counter may overflow", a symptom
16590 * indent.c (Fvertical_motion): Mark locals as initialized.
16591 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16593 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16595 * search.c (Fre_search_backward): Mention `case-fold-search' in
16596 all the re_search_* functions (bug#8138).

16619 (display_string): If we need to ignore text properties of
16620 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16621 original value of -1 will not work with bidi.)
16622 (compute_display_string_pos): First arg is now struct
16623 `text_pos *'; all callers changed. Support display properties on
16625 (compute_display_string_end): Support display properties on Lisp
16627 (init_iterator, reseat_1, reseat_to_string): Initialize the
16628 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16629 when iterating on a string not from display properties).
16630 (compute_display_string_pos, compute_display_string_end):
16631 Fix calculation of the object to scan. Fixes an error when using
16633 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16634 base_level_stop; instead, set base_level_stop to BEGV.
16635 Fixes crashes in vertical-motion.
16636 (next_element_from_buffer): Improve commentary for when
16637 the iterator is before prev_stop.
16638 (init_iterator): Initialize bidi_p from the default value of
16639 bidi-display-reordering, not from buffer-local value. Use the
16640 buffer-local value only if initializing for buffer iteration.

16650 (init_iterator): Don't initialize it->bidi_p for strings
16652 (reseat_to_string): Initialize it->bidi_p for strings here.

16661 parts of next_element_from_buffer, next_element_from_string, and
16662 next_element_from_c_string.
16663 (tool_bar_lines_needed, redisplay_tool_bar)
16664 (display_menu_bar): Force left-to-right direction. Add a FIXME
16665 comment for making that be controlled by a user option.

16675 iterator for displaying display or overlay strings.
16676 (forward_to_next_line_start): Don't use the shortcut if

16679 pushed the iterator stack, restore the internal state of the bidi
16680 iterator by calling bidi_pop_it same number of times.
16681 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16682 and we are bidi-iterating, don't decrement the iterator position;
16683 instead, set the first_elt flag in the bidi iterator, to produce
16685 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16686 (push_display_prop): xassert that we are iterating a buffer.

16690 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16691 correctly. Don't assume unibyte strings are not bidi-reordered.

16700 property. Fix a typo in popping stretch info. Add an assertion
16701 for verifying that the iterator position is in sync with the bidi
16703 (handle_single_display_spec, get_overlay_strings_1)

17115 (clone_per_buffer_values): Don't assume that

17117 This isn't true in general, and it's particularly not true
17118 if Emacs is configured with --with-wide-int.
17119 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17120 New macros, used in the buffer.c change.

17156 Random fixes. E.g., (random) never returned negative values.
17157 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17158 subseconds part to the entropy, as that's a bit more random.
17159 Prefer signed to unsigned, since the signedness doesn't matter and
17160 in general we prefer signed. When given a limit, use a
17161 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17162 latter isn't right if USE_2_TAGS_FOR_INTS.
17163 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17164 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17176 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17177 This is more efficient than Ffile_directory_p and avoids a minor race.

17181 * buffer.c (Foverlay_put): Say what the return value is
17184 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17185 is a directory before asking whether to use the file name

17188 error be more correct.
17190 * fns.c (Frequire): Remove the mention of the .gz files, since
17191 that's installation-specific, but keep the mention of
17192 `get-load-suffixes'.

17196 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17207 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17208 Also (re)move comments that are misplaced or no longer relevant.

17237 * lread.c (syms_of_lread): Mention single symbols defined by

17309 * eval.c (struct backtrace): Simplify and port the data structure.
17310 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17311 signed bit field, as this assumption is not portable and it makes
17312 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17313 "char debug_on_exit : 1" as this is not portable either; instead,
17314 use the portable "unsigned int debug_on_exit : 1". Remove unused
17315 member evalargs. Remove obsolete comments about cc bombing out.
17317 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17388 frames size_hint to set minimum and natural (Bug#8919).
17389 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17390 and use min_width/height from frames size_hint to set
17391 min_width/height (Bug#8919).

17403 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
17405 * process.c (wait_reading_process_output): Bypass select if
17406 waiting for a cell while ignoring keyboard input, and input is
17407 pending. Suggested by Jan Djärv (Bug#8869).
17409 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
17411 Use gnulib's dup2 module instead of rolling our own.
17412 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17483 * print.c (printchar, strout): Check for string overflow.
17484 (PRINTPREPARE, printchar, strout):
17485 Don't set size unless allocation succeeds.
17487 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17488 for sizes. Check for string overflow more accurately.
17489 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17491 * macros.c: Integer and buffer overflow fixes.
17492 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17493 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17497 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17499 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17501 * lread.c: Integer overflow fixes.
17502 (read_integer): Radix is now EMACS_INT, not int,
17503 to improve quality of diagnostics for out-of-range radices.
17504 Calculate buffer size correctly for out-of-range radices.
17505 (read1): Check for integer overflow in radices, and in
17506 read-circle numbers.
17507 (read_escape): Avoid int overflow.
17508 (Fload, openp, read_buffer_size, read1)
17509 (substitute_object_recurse, read_vector, read_list, map_obarray):
17510 Use ptrdiff_t, not int, for sizes.

17525 2011-06-22 Leo Liu <sdl.web@gmail.com>
17527 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17528 Move to minibuffer.el.
17530 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17532 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17533 The following patches are for when GLYPH_DEBUG && !XASSERT.
17534 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17535 * dispnew.c (flush_stdout):
17536 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17537 Mark as externally visible.
17538 * dispnew.c (check_window_matrix_pointers): Now static.
17539 * dispnew.c (window_to_frame_vpos):
17540 * xfns.c (unwind_create_frame):
17541 * xterm.c (x_check_font): Remove unused local.
17542 * scroll.c (CHECK_BOUNDS):
17543 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17544 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17545 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17546 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17547 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17549 (debug_method_add): Use va_list and vsprintf rather than relying
17550 on undefined behavior with wrong number of arguments.
17551 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17552 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17553 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17554 since we're not interested in debugging glyphs with old libraries.
17555 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17556 GCC 4.6.0's static checking.
17558 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17576 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17577 (.bitmaps_last, struct x_output.icon_bitmap):
17578 Use ptrdiff_t, not int, for bitmap indexes.
17579 (x_allocate_bitmap_record): Check for size overflow.
17580 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17582 Use ptrdiff_t, not int, for overlay counts.
17583 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17584 * editfns.c (overlays_around, get_pos_property):

17586 * xdisp.c (next_overlay_change, note_mouse_highlight):
17587 * xfaces.c (face_at_buffer_position):
17588 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17589 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17590 (Fnext_overlay_change, Fprevious_overlay_change)
17591 (mouse_face_overlay_overlaps, Foverlays_in):
17592 Use ptrdiff_t, not int, for sizes.
17593 (overlays_at, overlays_in): Check for size-calculation overflow.
17595 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17597 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17598 (x_session_initialize): Do not assume string length fits in int.
17600 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17601 This is unlikely, but can occur if DPI is outlandish.
17603 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17604 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

17607 * xrdb.c (magic_file_p, search_magic_path):
17608 Omit last arg SUFFIX; it was always 0. All callers changed.
17609 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17611 * xfont.c (xfont_match): Avoid need for strlen.
17613 * xfns.c: Don't assume strlen fits in int.

17616 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17617 not unsigned long, as we prefer signed integers. All callers changed.
17618 Detect integer overflow in repeat count.
17619 (message_dolog): Don't assume print length fits in 39 bytes.
17620 (display_mode_element): Don't assume strlen fits in int.
17622 * termcap.c: Don't assume sizes fit in int and never overflow.
17623 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.

17626 * minibuf.c (Fread_buffer):
17627 * lread.c (intern, intern_c_string):

17638 Don't assume integer property fits in fixnum.
17639 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17641 * filelock.c: Fix some buffer overrun and integer overflow issues.
17642 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17643 Reformulate so as not to need the command string.
17644 Invoke gzip -cd rather than gunzip, as it's more portable.
17645 (lock_info_type, lock_file_1, lock_file):
17646 Don't assume pid_t and time_t fit in unsigned long.
17647 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17648 (current_lock_owner): Prefer signed type for sizes.
17649 Use memcpy, not strncpy, where memcpy is what is really wanted.
17650 Don't assume (via atoi) that time_t and pid_t fit in int.
17651 Check for time_t and/or pid_t out of range, e.g., via a network share.
17652 Don't alloca where an auto var works fine.
17654 * fileio.c: Fix some integer overflow issues.
17655 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17656 Don't assume string length fits in int.
17657 (directory_file_name): Don't assume string length fits in long.
17658 (make_temp_name): Don't assume pid fits in int, or that its print
17659 length is less than 20.

17679 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17681 * lread.c (invalid_syntax): Omit length argument.
17682 All uses changed. This doesn't fix a bug, but it simplifies the
17683 code away from its former Hollerith-constant appearance, and it's
17684 one less 'int' to worry about when looking at integer-overflow issues.
17685 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17687 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17688 This didn't break anything, but it didn't help either.
17689 It's confusing to put a bogus integer in a place where the actual
17690 value does not matter.
17691 (LIST_END_P): Remove unused macro and its bogus comment.
17692 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17694 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17695 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17697 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17698 We prefer signed types, and the value cannot exceed the EMACS_INT
17699 range anyway (because otherwise the length would not be representable).
17700 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17701 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17702 This avoids a GCC warning when WIDE_EMACS_INT.
17704 * indent.c (sane_tab_width): New function.
17705 (current_column, scan_for_column, Findent_to, position_indentation)
17706 (compute_motion): Use it. This is just for clarity.
17707 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

17713 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17715 * editfns.c, insdel.c:
17716 Omit unnecessary forward decls, to simplify future changes.
17718 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17720 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17722 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17723 Use much-faster test for byte-length change.
17724 Don't assume string byte-length fits in 'int'.
17725 Check that character arg fits in 'int'.
17726 (mapcar1): Declare byte as byte, for clarity.
17728 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17730 * fns.c (concat): Catch string overflow earlier.
17731 Do not rely on integer wraparound.
17733 * dispextern.h (struct it.overlay_strings_charpos)
17734 (struct it.selective): Now EMACS_INT, not int.
17735 * xdisp.c (forward_to_next_line_start)
17736 (back_to_previous_visible_line_start)
17737 (reseat_at_next_visible_line_start, next_element_from_buffer):
17738 Don't arbitrarily truncate the value of 'selective' to int.
17740 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17742 * composite.c: Don't truncate sizes to 'int'.
17743 (composition_gstring_p, composition_reseat_it)
17744 (composition_adjust_point): Use EMACS_INT, not int.
17745 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17746 not EMACS_UINT, for indexes.
17748 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17750 * buffer.c: Include <verify.h>.
17751 (struct sortvec.priority, struct sortstr.priority):
17752 Now EMACS_INT, not int.
17753 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17754 (struct sortstr.size, record_overlay_string)
17755 (struct sortstrlist.size, struct sortlist.used):
17756 Don't truncate size to int.
17757 (record_overlay_string): Check for size-calculation overflow.
17758 (init_buffer_once): Check at compile-time, not run-time.
17760 2011-06-22 Jim Meyering <meyering@redhat.com>
17762 Don't leak an XBM-image-sized buffer
17763 * image.c (xbm_load): Free the image buffer after using it.
17765 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17768 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17769 that Sun C diagnosed.
17770 * fns.c (secure_hash): Fix pointer signedness issue.
17771 * intervals.c (static_offset_intervals): New function.
17772 (offset_intervals): Use it.
17774 2011-06-21 Leo Liu <sdl.web@gmail.com>
17777 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17780 * fns.c (secure_hash): Rename from crypto_hash_function and change
17781 the first arg to accept symbols.
17782 (Fsecure_hash): New primitive.
17783 (syms_of_fns): New symbols.
17785 2011-06-20 Deniz Dogan <deniz@dogan.se>
17787 * process.c (Fset_process_buffer): Clarify return value in
17790 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17792 * dispnew.c (add_window_display_history): Use BVAR.

17798 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17801 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17802 check till after the cache is created in init_frame_faces.
17804 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17806 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17808 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17810 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17811 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17812 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17814 Improve buffer-overflow checking (Bug#8873).
17815 * fileio.c (Finsert_file_contents):
17816 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17817 Remove the old (too-loose) buffer overflow checks.
17818 They weren't needed, since make_gap checks for buffer overflow.
17819 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17820 The old code merely checked for Emacs fixnum overflow, and relied
17821 on undefined (wraparound) behavior. The new code avoids undefined
17822 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17824 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17825 Tune. Don't use wider integers than needed. Don't use alloca.
17826 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17828 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17830 * insdel.c, lisp.h (buffer_overflow): New function.
17831 (insert_from_buffer_1, replace_range, replace_range_2):
17832 * insdel.c (make_gap_larger):
17833 * editfns.c (Finsert_char):
17834 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17836 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17838 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17840 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17842 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17843 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17845 * fileio.c: Don't assume EMACS_INT fits in off_t.
17846 (emacs_lseek): New static function.
17847 (Finsert_file_contents, Fwrite_region): Use it.
17848 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17850 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17852 * fns.c: Don't overflow int when computing a list length.
17853 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17854 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17855 truncation on 64-bit hosts. Check for QUIT every
17856 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17857 faster and is responsive enough.
17858 (Flength): Report an error instead of overflowing an integer.
17859 (Fsafe_length): Return a float if the value is not representable
17860 as a fixnum. This shouldn't happen except in contrived situations.
17861 (Fnthcdr, Fsort): Don't assume list length fits in int.
17862 (Fcopy_sequence): Don't assume vector length fits in int.
17864 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17865 (header_size, word_size): New constants.
17866 (allocate_vectorlike): Don't check size overflow here.
17867 (allocate_vector): Check it here instead, since this is the only
17868 caller of allocate_vectorlike that could cause overflow.
17869 Check that the new vector's length is representable as a fixnum.
17871 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17872 The previous code was bogus. For example, next_almost_prime (32)
17873 returned 39, which is undesirable as it is a multiple of 3; and
17874 next_almost_prime (24) returned 25, which is a multiple of 5 so
17875 why was the code bothering to check for multiples of 7?
17877 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17879 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17881 Variadic C functions now count arguments with ptrdiff_t.
17882 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17883 Back then I didn't know that the Emacs coding style prefers signed int.
17884 Also, in the meantime I found a few more instances where arguments
17885 were being counted with int, which may truncate counts on 64-bit
17886 machines, or EMACS_INT, which may be unnecessarily wide.
17887 * lisp.h (struct Lisp_Subr.function.aMANY)
17888 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17889 Arg counts are now ptrdiff_t, not size_t.
17890 All variadic functions and their callers changed accordingly.
17891 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17892 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17893 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17894 * callint.c (Fcall_interactively): Check arg count for overflow,
17895 to avoid potential buffer overrun. Use signed char, not 'int',
17896 for 'varies' array, so that we needn't bother to check its size
17897 calculation for overflow.
17898 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17899 * eval.c (apply_lambda):
17900 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17901 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17902 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17904 * callint.c (Fcall_interactively): Don't use index var as event count.
17906 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17907 * mem-limits.h (SIZE): Remove; no longer used.
17909 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17911 Remove unnecessary casts.
17912 * xterm.c (x_term_init):
17913 * xfns.c (x_set_border_pixel):
17914 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17915 These aren't needed now that we assume ANSI C.
17917 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17918 It's more likely to cause problems (due to unsigned overflow)
17921 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17923 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17925 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17927 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17929 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17931 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17933 GLYPH_CODE_FACE returns EMACS_INT, not int.
17934 * dispextern.h (merge_faces):
17935 * xfaces.c (merge_faces):
17936 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17937 Don't assume EMACS_INT fits in int.
17939 * character.h (CHAR_VALID_P): Remove unused parameter.
17940 * fontset.c, lisp.h, xdisp.c: All uses changed.
17942 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17944 * fns.c (concat): Minor tuning based on overflow analysis.
17945 This doesn't fix any bugs. Use int to hold character, instead
17946 of constantly refetching from Emacs object. Use XFASTINT, not
17947 XINT, for value known to be a character. Don't bother comparing
17948 a single byte to 0400, as it's always less.
17950 * floatfns.c (Fexpt):
17951 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17953 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17956 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17958 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17959 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17960 incorrectly succeed when S was a string, because 4294967386 was
17961 truncated before it was used.
17963 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17964 Otherwise, an out-of-range integer could cause undefined behavior
17967 * composite.c: Use int, not EMACS_INT, for characters.
17968 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17969 EMACS_INT, for values that are known to be in character range.
17970 This doesn't fix any bugs but is the usual style inside Emacs and
17971 may generate better code on 32-bit machines.
17973 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17974 This is for reasons similar to the recent CHAR_STRING fix.
17975 * charset.c (Fencode_char): Check that character arg is actually
17976 a character. Pass an int to ENCODE_CHAR.
17977 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17978 wider than 'int', as a compile-time check to prevent future regressions
17981 * character.c (char_string): Remove unnecessary casts.
17983 Make sure a 64-bit char is never passed to CHAR_STRING.
17984 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17985 by silently ignoring the top 32 bits, allowing some values
17986 that were far too large to be valid characters.
17987 * character.h: Include <verify.h>.
17988 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17989 arguments are no wider than unsigned, as a compile-time check
17990 to prevent future regressions in this area.
17992 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17993 (Fsubst_char_in_region):
17995 * xdisp.c (decode_mode_spec_coding):
17996 Adjust to CHAR_STRING's new requirement.
17997 * editfns.c (Finsert_char, Fsubst_char_in_region):
17998 * fns.c (concat): Check that character args are actually
17999 characters. Without this test, these functions did the wrong
18000 thing with wildly out-of-range values on 64-bit hosts.
18002 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18003 These casts should not be needed on 32-bit hosts, either.
18004 * keyboard.c (read_char):
18005 * lread.c (Fload): Remove casts to unsigned.
18007 * lisp.h (UNSIGNED_CMP): New macro.
18008 This fixes comparison bugs on 64-bit hosts.
18009 (ASCII_CHAR_P): Use it.
18010 * casefiddle.c (casify_object):
18011 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18012 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18013 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18014 * dispextern.h (FACE_FROM_ID):
18015 * keyboard.c (read_char): Use UNSIGNED_CMP.
18017 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18018 not to EMACS_INT, to avoid GCC warning.
18020 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18022 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18023 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18024 isn't needed on 32-bit machines.
18026 * buffer.c (Fgenerate_new_buffer_name):
18027 Use EMACS_INT for count, not int.
18028 (advance_to_char_boundary): Return EMACS_INT, not int.
18030 * data.c (Qcompiled_function): Now static.
18032 * window.c (window_body_lines): Now static.
18034 * image.c (gif_load): Rename local to avoid shadowing.
18036 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18037 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18038 * alloc.c (make_save_value): Integer argument is now of type
18039 ptrdiff_t, not int.
18040 (mark_object): Use ptrdiff_t, not int.
18041 * lisp.h (pD): New macro.
18042 * print.c (print_object): Use it.
18044 * alloc.c: Use EMACS_INT, not int, to count objects.
18045 (total_conses, total_markers, total_symbols, total_vector_size)
18046 (total_free_conses, total_free_markers, total_free_symbols)
18047 (total_free_floats, total_floats, total_free_intervals)
18048 (total_intervals, total_strings, total_free_strings):
18049 Now EMACS_INT, not int. All uses changed.
18050 (Fgarbage_collect): Compute overall total using a double, so that
18051 integer overflow is less likely to be a problem. Check for overflow
18052 when converting back to an integer.
18053 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18054 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18055 These were 'int' variables that could overflow on 64-bit hosts;
18056 they were never used, so remove them instead of repairing them.
18057 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18058 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18059 Previously, this ceilinged at INT_MAX, but that doesn't work on
18061 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18063 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18064 (allocate_vectorlike): Check for ptrdiff_t overflow.
18065 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18066 when a (possibly-narrower) signed value would do just as well.
18067 We prefer using signed arithmetic, to avoid comparison confusion.
18069 * alloc.c: Catch some string size overflows that we were missing.
18070 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18071 for convenience in STRING_BYTES_MAX.
18072 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18073 The definition here is exact; the one in lisp.h was approximate.
18074 (allocate_string_data): Check for string overflow. This catches
18075 some instances we weren't catching before. Also, it catches
18076 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18077 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18078 and ptrdiff_t and EMACS_INT are both 64 bits.
18080 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18081 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18082 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18084 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18086 * alloc.c (Fmake_string): Check for out-of-range init.
18088 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18090 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18092 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18094 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18095 xg_get_default_scrollbar_width.
18097 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18098 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18099 (style_changed_cb): Call update_theme_scrollbar_width and call
18100 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18101 all frames (Bug#8505).
18102 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18103 Call gtk_window_set_resizable if HAVE_GTK3.
18104 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18105 and height if HAVE_GTK3 (Bug#8505).
18106 (scroll_bar_width_for_theme): New variable.
18107 (update_theme_scrollbar_width): New function.
18108 (xg_get_default_scrollbar_width): Move code to
18109 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18110 (xg_initialize): Call update_theme_scrollbar_width.
18112 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18114 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18116 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18118 * frame.c (make_frame): Call other_buffer_safely instead of
18121 * window.c (temp_output_buffer_show): Call display_buffer with
18122 second argument Vtemp_buffer_show_specifiers and reset latter
18123 immediately after the call.
18124 (Vtemp_buffer_show_specifiers): New variable.
18125 (auto_window_vscroll_p, next_screen_context_lines)
18126 (Vscroll_preserve_screen_position): Remove leading asterisks from
18129 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18131 Fix minor problems found by GCC 4.6.0 static checking.
18132 * buffer.c (Qclone_number): Remove for now, as it's unused.
18133 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18134 (record_buffer): Remove unused local.
18135 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18136 (set_frame_buffer_list): Remove; unused.
18137 * frame.h (other_visible_frames): Remove decl.
18138 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18139 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18140 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18142 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18143 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18144 Define only if HAVE_GPM.
18145 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18146 (update_hints_inhibit): Remove; never set. All uses removed.
18147 * widgetprv.h (emacsFrameClassRec): Remove decl.
18148 * window.c (delete_deletable_window): Now returns void, since it
18149 wasn't returning anything.
18150 (compare_window_configurations): Remove unused locals.
18151 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18152 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18153 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18154 the same widths as pointers. This follows up on the 2011-05-06 patch.
18155 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18156 * xterm.h: Likewise.
18157 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18159 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18161 * makefile.w32-in: Update dependencies.
18162 (LISP_H): Add lib/intprops.h.
18164 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18166 * image.c (gif_load): Add animation frame delay to the metadata.
18167 (syms_of_image): Use DEFSYM. New symbol `delay'.
18169 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18171 * window.c (delete_deletable_window): Re-add.
18172 (Fset_window_configuration): Rewrite to handle dead buffers and
18173 consequently deletable windows.
18174 (window_tree, Fwindow_tree): Remove. Supply functionality in
18176 (compare_window_configurations): Simplify code.
18178 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18180 * image.c (imagemagick_load_image): Fix type mismatch.
18181 (Fimagemagick_types): Likewise.
18183 * window.h (replace_buffer_in_windows): Declare.
18185 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18187 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18188 Qclone_number. Remove external declaration of Qdelete_window.
18189 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18191 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18192 Run Qbuffer_list_update_hook if allowed.
18193 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18194 buffer list implementation.
18195 (other_buffer_safely): New function.
18196 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18197 calls to replace_buffer_in_windows and
18198 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18200 (record_buffer): Inhibit quitting and rewrite using quittable
18201 functions. Run Qbuffer_list_update_hook if allowed.
18202 (Frecord_buffer, Funrecord_buffer): New functions.
18203 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18204 Move switch-to-buffer to window.el.
18205 (bury-buffer): Move to window.el.
18206 (Vbuffer_list_update_hook): New variable.
18208 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18211 * window.h (resize_frame_windows): Move up in code.
18212 (Fwindow_frame): Remove EXFUN.
18213 (replace_buffer_in_all_windows): Remove prototype.
18214 (replace_buffer_in_windows_safely): Add prototype.
18216 * window.c: Declare Qdelete_window static again. Move down
18217 declaration of select_count.
18218 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18219 (Fother_window): Move to window.el.
18220 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18221 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18222 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18224 (replace_buffer_in_windows): Implement by calling
18225 Qreplace_buffer_in_windows.
18226 (replace_buffer_in_all_windows): Remove with some functionality
18227 moved into replace_buffer_in_windows_safely.
18228 (replace_buffer_in_windows_safely): New function.
18229 (select_window_norecord, select_frame_norecord): Move in front
18230 of run_window_configuration_change_hook. Remove now obsolete
18232 (Fset_window_buffer): Rewrite doc-string.
18233 Call Qrecord_window_buffer.
18234 (keys_of_window): Move binding for other-window to window.el.
18236 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18238 * dispextern.h (struct image): Replace data member, whose int_val
18239 and ptr_val fields were not used by anything, with a single
18242 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18243 (gif_clear_image, gif_load, imagemagick_load_image)
18244 (gs_clear_image, gs_load): Callers changed.

18688 (compute_display_string_pos): Accept additional argument
18689 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18690 value of a `display' property is a "replacing spec".
18691 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18692 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18693 the display property, but just return a value indicating whether
18694 the display property will replace the characters it covers.
18695 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18696 frame_window_p members of struct bidi_it.
18697 (compute_display_string_pos, compute_display_string_end):
18699 (push_it): Accept second argument POSITION, where pop_it should
18700 jump to continue iteration.
18701 (reseat_1): Initialize bidi_it.disp_pos.
18703 * keyboard.c (adjust_point_for_property): Adjust the call to
18704 display_prop_intangible_p to its new signature.

18709 (compute_display_string_pos, compute_display_string_end):
18710 Declare prototypes.
18711 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18714 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18716 Malloc failure behavior now depends on size of allocation.
18717 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18718 * lisp.h: Change signatures accordingly.
18719 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18720 All callers changed. (Bug#8762)
18722 * gnutls.c: Use Emacs's memory allocators.
18723 Without this change, the gnutls library would invoke malloc etc.
18724 directly, which causes problems on non-SYNC_INPUT hosts, and which
18725 runs afoul of improving memory_full behavior. (Bug#8761)
18726 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18727 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18728 xfree instead of the default malloc, realloc, free.
18729 (Fgnutls_boot): No need to check for memory allocation failure,
18730 since xmalloc does that for us.
18732 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18733 * category.c (hash_get_category_set):
18734 * ccl.c (ccl_driver):
18735 * charset.c (Fdefine_charset_internal):
18736 * charset.h (struct charset.hash_index):
18737 * composite.c (get_composition_id, gstring_lookup_cache)
18738 (composition_gstring_put_cache):
18739 * composite.h (struct composition.hash_index):
18740 * dispextern.h (struct image.hash):
18741 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
18742 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

18746 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18747 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18748 * image.c (make_image, search_image_cache, lookup_image)
18749 (xpm_put_color_table_h):
18750 * lisp.h (struct Lisp_Hash_Table):
18751 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18752 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18753 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18754 * alloc.c (allocate_vectorlike):
18755 Check for overflow in vector size calculations.
18756 * ccl.c (ccl_driver):
18757 Check for overflow when converting EMACS_INT to int.
18758 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18759 need to be updated by these changes.
18760 * fns.c (make_hash_table, maybe_resize_hash_table):
18761 Check for integer overflow with large hash tables.
18762 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18763 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18764 (SXHASH_REDUCE): New macro.
18765 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18766 Use it instead of discarding useful hash info with large hash values.
18767 (sxhash_float): New function.
18768 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18769 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18770 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18771 Rewrite to use FIXNUM_BITS, as this simplifies things.
18772 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18773 Adjust signatures to match updated version of code.
18774 (consing_since_gc): Now EMACS_INT, since a single hash table can
18775 use more than INT_MAX bytes.
18777 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18779 Make it possible to build with GCC-4.6+ -O2 -flto.
18781 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18783 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18785 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18786 Call minibuffer-inactive-mode.
18788 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18790 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18791 Update dependencies.
18793 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18795 * data.c (init_data): Remove code for UTS, this system is not
18798 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18800 Don't force ./temacs to start in terminal mode.
18802 * frame.c (make_initial_frame): Initialize faces in all cases, not
18803 only when CANNOT_DUMP is defined.
18804 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18806 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18808 * dispnew.c (add_window_display_history): Use const for the string
18809 pointer. Remove declaration, not needed.
18811 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18813 Use 'inline', not 'INLINE'.
18814 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18815 * alloc.c, fontset.c (INLINE): Remove.
18816 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18817 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18818 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18819 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18820 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18822 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18824 Make it possible to run ./temacs.
18826 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18827 syms_of_callproc does the same thing. Remove test for
18828 "initialized", do it in the caller.
18829 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18831 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18833 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18834 (read_minibuf): Use get_minibuffer.
18835 (syms_of_minibuf): Use DEFSYM.
18836 (Qmetadata): New var.
18837 * data.c (Qbuffer): Don't make it static.
18838 (syms_of_data): Use DEFSYM.
18840 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18842 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18843 (CCL_CODE_MIN): New macro.
18845 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18847 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18849 * eval.c (Qdebug): Now static.
18850 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18851 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18852 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18854 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18856 * image.c: Various fixes to ImageMagick code comments.
18857 (Fimagemagick_types): Doc fix.
18859 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18861 Minor fixes prompted by GCC 4.6.0 warnings.
18863 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18865 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18866 (x_clipboard_manager_save_all): Move extern decl to ...
18867 * xterm.h: ... here, so that it can be checked for consistency.
18869 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18871 * xselect.c (x_clipboard_manager_save_frame)
18872 (x_clipboard_manager_save_all): New functions.
18873 (Fx_clipboard_manager_save): Lisp function deleted.
18875 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18876 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18878 * xterm.h: Update prototype.
18880 2011-05-28 William Xu <william.xwl@gmail.com>
18882 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18883 exiting (Bug#8239).
18885 2011-05-28 Jim Meyering <meyering@redhat.com>
18887 Avoid a sign-extension bug in crypto_hash_function.
18888 * fns.c (to_uchar): Define.
18889 (crypto_hash_function): Use it to convert some newly-signed
18890 variables to unsigned, to avoid sign-extension bugs. For example,
18891 without this change, (md5 "truc") would evaluate to
18892 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18893 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18894 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18896 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18898 Integer overflow fixes.
18900 * dbusbind.c: Serial number integer overflow fixes.
18901 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18902 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18903 to hold a serial number that is too large for a fixnum.
18904 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18905 Check for serial numbers out of range. Decode any serial number
18906 that was so large that it became a float. (Bug#8722)
18908 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18909 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18910 Use XFASTINT rather than XUINT when numbers are nonnegative.
18911 (xd_append_arg, Fdbus_method_return_internal):
18912 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18913 arguments, check that Lisp number is nonnegative, rather than
18914 silently wrapping negative numbers around. (Bug#8722)
18915 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18918 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18920 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18922 ccl: Add integer overflow checks.
18923 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18924 (IN_INT_RANGE): New macros.
18925 (ccl_driver): Use them to check for integer overflow when
18926 decoding a CCL program. Many of the new checks are whether XINT (x)
18927 fits in int; it doesn't always, on 64-bit hosts. The new version
18928 doesn't catch all possible integer overflows, but it's an
18929 improvement. (Bug#8719)
18931 * alloc.c (make_event_array): Use XINT, not XUINT.
18932 There's no need for unsigned here.
18934 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18935 This follows up to the 2011-05-06 change that substituted uintptr_t
18936 for EMACS_INT. This case wasn't caught back then.
18938 Rework Fformat to avoid integer overflow issues.
18939 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18940 now (part of C89). Include <verify.h>.
18941 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18942 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18943 (Fformat): Avoid the prepass trying to compute sizes; it was only
18944 approximate and thus did not catch overflow reliably. Instead, walk
18945 through the format just once, formatting and computing sizes as we go,
18946 checking for integer overflow at every step, and allocating a larger
18947 buffer as needed. Keep track separately whether the format is
18948 multibyte. Keep only the most-recently calculated precision, rather
18949 than them all. Record whether each argument has been converted to
18950 string. Use EMACS_INT, not int, for byte and char and arg counts.
18951 Support field widths and precisions larger than INT_MAX. Avoid
18952 sprintf's undefined behavior with conversion specifications such as %#d
18953 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18954 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18955 formatting out-of-range floating point numbers with int
18956 formats. (Bug#8668)
18958 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18960 * data.c: Avoid integer truncation in expressions involving floats.
18961 * data.c: Include <intprops.h>.
18962 (arith_driver): When there's an integer overflow in an expression
18963 involving floating point, convert the integers to floating point
18964 so that the resulting value does not suffer from catastrophic
18965 integer truncation. For example, on a 64-bit host (* 4
18966 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18967 Do not rely on undefined behavior after integer overflow.
18969 merge count_size_as_multibyte, parse_str_to_multibyte
18970 * character.c, character.h (count_size_as_multibyte):
18971 Rename from parse_str_to_multibyte; all uses changed.
18972 Check for integer overflow.
18973 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18974 since it's now a duplicate of the other. This is more of
18975 a character than a buffer op, so better that it's in character.c.
18976 * fns.c, print.c: Adjust to above changes.
18978 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18980 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18982 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18984 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18985 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18986 (x_clipboard_manager_save): Now static.
18987 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18989 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18990 (crypto_hash_function): Now static.
18991 Fix pointer signedness problems. Avoid unnecessary initializations.
18993 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18995 * termhooks.h (Vselection_alist): Make it terminal-local.
18997 * terminal.c (create_terminal): Initialize it.
18999 * xselect.c: Support for clipboard managers.
19000 (Vselection_alist): Move to termhooks.h as terminal-local var.
19001 (LOCAL_SELECTION): New macro.
19002 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19003 (symbol_to_x_atom): Remove gratuitous arg.
19004 (x_handle_selection_request, lisp_data_to_selection_data)
19005 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19006 (x_own_selection, x_get_local_selection, x_convert_selection):
19007 New arg, specifying work frame. Use terminal-local Vselection_alist.
19008 (some_frame_on_display): Delete unused function.
19009 (Fx_own_selection_internal, Fx_get_selection_internal)
19010 (Fx_disown_selection_internal, Fx_selection_owner_p)
19011 (Fx_selection_exists_p): New optional frame arg.
19012 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19013 (x_handle_selection_clear): Don't treat other terminals with the
19014 same keyboard specially. Use the terminal-local Vselection_alist.
19015 (x_clear_frame_selections): Use Frun_hook_with_args.
19017 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19019 * xterm.h: Add support for those atoms.
19021 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19023 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19024 (converted_selections, conversion_fail_tag): New global variables.
19025 (x_selection_request_lisp_error): Free the above.
19026 (x_get_local_selection): Remove unnecessary code.
19027 (x_reply_selection_request): Args changed; handle arbitrary array
19028 of converted selections stored in converted_selections.
19029 Separate the XChangeProperty and SelectionNotify steps.
19030 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19031 (x_convert_selection): New function.
19032 (x_handle_selection_event): Simplify.
19033 (x_get_foreign_selection): Don't ignore incoming requests while
19034 waiting for an answer; this will fail when we implement
19035 SAVE_TARGETS, and seems unnecessary anyway.
19036 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19037 (Vx_sent_selection_functions): Doc fix.
19039 2011-05-26 Leo Liu <sdl.web@gmail.com>
19041 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19043 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19045 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19047 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19048 for fringe update if it has periodic bitmap.
19049 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19050 and fringe_bitmap_periodic_p.
19052 * fringe.c (get_fringe_bitmap_data): New function.
19053 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19054 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19055 row. Mark glyph row for fringe update if periodicity changed.
19057 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19058 for fringe update unless it has periodic bitmap.
19060 2011-05-25 Kenichi Handa <handa@m17n.org>

19077 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19078 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19079 Remove macros that are defined and never used.
19080 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19082 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19084 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19085 (Fx_get_selection_internal): Minor cleanup.
19086 (Fx_own_selection_internal): Rename arguments for consistency with
19089 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

19113 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19115 * systime.h (Time): Define only if emacs is defined.
19116 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19117 where the include path doesn't have X11/X.h by default. See
19118 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19120 2011-05-20 Kenichi Handa <handa@m17n.org>
19122 * composite.c (find_automatic_composition): Fix previous change.
19124 2011-05-20 Glenn Morris <rgm@gnu.org>
19126 * lisp.mk: New file, split from Makefile.in.
19127 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19128 (shortlisp): Remove.
19129 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19131 2011-05-19 Glenn Morris <rgm@gnu.org>
19133 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19134 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19135 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19136 (lisp): Set the order to that of loadup.el.
19137 (shortlisp): Make it a copy of $lisp.
19138 (SOME_MACHINE_LISP): Remove.
19139 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19140 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19142 2011-05-18 Kenichi Handa <handa@m17n.org>
19144 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19145 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19146 (find_automatic_composition): Mostly rewrite for efficiency.
19148 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19150 * makefile.w32-in: Update dependencies.
19152 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19154 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19155 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19157 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19159 Fix some integer overflow issues, such as string length overflow.
19161 * insdel.c (count_size_as_multibyte): Check for string overflow.
19163 * character.c (lisp_string_width): Check for string overflow.
19164 Use EMACS_INT, not int, for string indexes and lengths; in
19165 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19166 the resulting string length overflows an EMACS_INT; instead,
19167 report a string overflow if no precision given. When checking for
19168 precision exhaustion, use a check that cannot possibly have
19169 integer overflow. (Bug#8675)
19170 * character.h (lisp_string_width): Adjust to new signature.
19172 * alloc.c (string_overflow): New function.
19173 (Fmake_string): Use it. This doesn't change behavior, but saves
19174 a few bytes and will simplify future changes.
19175 * character.c (string_escape_byte8): Likewise.
19176 * lisp.h (string_overflow): New decl.
19178 Fixups, following up to the user-interface timestamp change.
19179 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19180 for UI timestamps, instead of unsigned long.
19181 * msdos.c (mouse_get_pos): Likewise.
19182 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19183 * w32gui.h (Time): Define by including "systime.h" rather than by
19184 declaring it ourselves. (Bug#8664)
19186 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19187 * image.c (clear_image_cache): Likewise.
19189 * term.c (term_mouse_position): Don't assume time_t wraparound.
19191 Be more systematic about user-interface timestamps.
19192 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19193 and sometimes 'EMACS_UINT', to represent these timestamps.
19194 This change causes it to use 'Time' uniformly, as that's what X uses.
19195 This makes the code easier to follow, and makes it easier to catch
19196 integer overflow bugs such as Bug#8664.
19197 * frame.c (Fmouse_position, Fmouse_pixel_position):
19198 Use Time, not unsigned long, for user-interface timestamps.
19199 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19200 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19201 * keyboard.h (last_event_timestamp): Likewise.
19202 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19203 * menu.h (xmenu_show): Likewise.
19204 * term.c (term_mouse_position): Likewise.
19205 * termhooks.h (struct input_event.timestamp): Likewise.
19206 (struct terminal.mouse_position_hook): Likewise.
19207 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19208 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19209 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19210 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19211 what it was before.
19212 * menu.h, termhooks.h: Include "systime.h", for Time.
19214 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19215 Don't assume that the difference between two unsigned long values
19216 can fit into an integer. At this point, we know button_down_time
19217 <= event->timestamp, so the difference must be nonnegative, so
19218 there's no need to cast the result if double-click-time is
19219 nonnegative, as it should be; check that it's nonnegative, just in
19220 case. This bug is triggered when events are more than 2**31 ms
19221 apart (about 25 days). (Bug#8664)
19223 * xselect.c (last_event_timestamp): Remove duplicate decl.
19224 (x_own_selection): Remove needless cast to unsigned long.
19226 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19227 that always fit in int. Use a sentinel instead of a counter, to
19228 avoid a temp and to allay GCC's concerns about possible int overflow.
19229 * frame.h (struct frame): Use int for menu_bar_items_used
19230 instead of EMACS_INT, since it always fits in int.
19232 * menu.c (grow_menu_items): Check for int overflow.
19234 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19236 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19237 Before, the code was not consistent. These values cannot exceed
19238 2**31 - 1 so there's no need to make them unsigned.
19239 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19240 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19241 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19243 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19245 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19246 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19247 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19248 presumably because the widths might not match.
19250 * window.c (size_window): Avoid needless test at loop start.
19252 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19254 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19256 2011-05-12 Drew Adams <drew.adams@oracle.com>
19258 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19260 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19262 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19263 `width' to `bar_area_x' and `bar_area_width', respectively.
19264 (x_scroll_run): Take account of fringe background extension.
19266 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19267 Rename local vars `left' and `width' to `bar_area_x' and
19268 `bar_area_width', respectively.
19269 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19270 background extension.
19272 2011-05-10 Jim Meyering <meyering@redhat.com>
19274 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19276 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19278 * image.c (Finit_image_library): Return t for built-in image types,
19279 like pbm and xbm. (Bug#8640)
19281 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19283 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19285 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19287 * w32console.c (Fset_screen_color): Doc fix.
19288 (Fget_screen_color): New function.
19289 (syms_of_ntterm): Defsubr it.
19291 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19292 unlink the temporary file if Fcall_process didn't create it in the
19294 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19295 child process will be redirected to a file specified with `:file'.
19296 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19297 cue to call_process_cleanup not to close that handle.
19299 2011-05-07 Ben Key <bkey76@gmail.com>
19301 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19302 one of two shell specific rules, either bootstrap-temacs-CMD or
19303 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19304 to the previous implementation of the bootstrap-temacs rule.
19305 The bootstrap-temacs-CMD rule is similar to the previous
19306 implementation of the bootstrap-temacs rule except that it
19307 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19310 These changes, along with some changes to nt/configure.bat,
19311 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19312 earlier fix to add support for --cflags and --ldflags options
19313 that include quotes so that it works whether make uses cmd or
19316 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19318 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19319 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19321 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19322 a string. Handle both cases.
19323 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19324 (Fdbus_register_method): Use Qinvalid_function.
19326 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19328 * makefile.w32-in: Update dependencies.
19329 (LISP_H): Add inttypes.h and stdin.h.
19330 (PROCESS_H): Add unistd.h.
19332 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19334 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19335 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19337 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19339 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19341 * term.c (vfatal): Remove stray call to va_end.
19342 It's not needed and the C Standard doesn't allow it here anyway.
19344 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19345 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19347 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19350 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19352 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19354 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19356 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19358 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19360 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19361 * charset.c (Fdefine_charset_internal): Don't initialize
19362 charset.code_space[15]. The value was garbage, on hosts with
19363 32-bit int (Bug#8600).
19365 * lread.c (read_integer): Be more consistent with string-to-number.
19366 Use string_to_number to do the actual conversion; this avoids
19367 rounding errors and fixes some other screwups. Without this fix,
19368 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19369 (digit_to_number): Move earlier, for benefit of read_integer.
19370 Return -1 if the digit is out of range for the base, -2 if it is
19371 not a digit in any supported base. (Bug#8602)
19373 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19375 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19376 to match comment at start of function. This also removes a
19377 GCC warning about overflow in a 32+64-bit port.
19379 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19381 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19382 Reported by Stefan Monnier in
19383 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19384 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19385 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19387 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19388 (EMACS_UINTPTR): Likewise, with uintptr_t.
19390 * lisp.h: Prefer 64-bit EMACS_INT if available.
19391 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19392 on 32-bit hosts that have 64-bit int, so that they can access
19394 However, temporarily disable this change unless the temporary
19395 symbol WIDE_EMACS_INT is defined.
19397 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19399 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19400 This removes an assumption that EMACS_INT and long are the same
19401 width as pointers. The assumption is true for Emacs porting targets
19402 now, but we want to make other targets possible.
19403 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19404 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19405 In the rest of the code, change types of integers that hold casted
19406 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19407 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19408 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19409 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19410 No need to cast type when ORing.
19411 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19412 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19413 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19414 assume EMACS_INT is the same width as char *.
19415 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19416 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19417 Remove no-longer-needed casts.
19418 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19419 (xg_tool_bar_help_callback, xg_make_tool_item):
19420 Use EMACS_INTPTR to hold an integer
19421 that will be cast to void *; this can avoid a GCC warning
19422 if EMACS_INT is not the same width as void *.
19423 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19424 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19425 (current_message_1, set_message_1):
19426 Use a local to convert to proper width without a cast.
19427 * xmenu.c (dialog_selection_callback): Likewise.
19429 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19430 Also, don't assume VALBITS / RAND_BITS is less than 5,
19431 and don't rely on undefined behavior when shifting a 1 left into
19433 * lisp.h (get_random): Change signature to match.
19435 * lread.c (hash_string): Use size_t, not int, for hash computation.
19436 Normally we prefer signed values; but hashing is special, because
19437 it's better to use unsigned division on hash table sizes so that
19438 the remainder is nonnegative. Also, size_t is the natural width
19439 for hashing into memory. The previous code used 'int', which doesn't
19440 retain enough info to hash well into very large tables.
19441 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19443 * dbusbind.c: Don't possibly lose pointer info when converting.
19444 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19445 Use XPNTR rather than XHASH, so that the high-order bits of
19446 the pointer aren't lost when converting through void *.
19448 * eval.c (Fautoload): Don't double-shift a pointer.
19450 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19452 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19454 * gnutls.c (DEF_GNUTLS_FN):
19455 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19457 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19459 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19462 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19464 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19465 New version that can reserve upto 2GB of heap space.
19467 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19469 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19471 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19473 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19474 `gnutls_certificate_set_x509_key_file'.
19476 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19478 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19479 Update dependencies.
19481 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19483 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19484 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19485 Remove unused parameter `fildes'.
19486 * process.c (read_process_output, send_process): Don't pass it.
19488 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19490 Fix previous change: the library cache is defined in w32.c.
19491 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19492 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19494 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19496 Implement dynamic loading of GnuTLS on Windows.
19498 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19499 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19500 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19503 * gnutls.c (Qgnutls_dll): Define.
19504 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19505 (gnutls_*): Declare function pointers.
19506 (init_gnutls_functions): New function to initialize function pointers.
19507 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19508 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19509 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19510 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19511 (emacs_gnutls_write, emacs_gnutls_read)
19512 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19513 (Fgnutls_available_p): New function.
19514 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19515 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19516 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19518 * image.c: Include w32.h.
19519 (Vimage_type_cache): Delete.
19520 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19521 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19522 (w32_delayed_load): Move to w32.c.
19524 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19526 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19527 (w32_delayed_load): Move from image.c. When loading a library, record
19528 its filename in the :loaded-from property of the library id.
19529 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19530 Initialize and staticpro them.
19531 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19533 * process.c: Include lisp.h before w32.h, not after.
19534 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19535 instead of gnutls_record_check_pending.
19537 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19539 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19541 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

19584 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19586 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19587 rather than `XVECTOR (FOO)->size'.
19589 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19590 inttypes.h, as a gnulib replacement is used if it not available in
19593 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19595 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19596 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19597 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19599 * coding.c (coding_alloc_by_realloc): Error out if destination
19600 will grow beyond MOST_POSITIVE_FIXNUM.
19601 (decode_coding_emacs_mule): Abort if there isn't enough place in

19603 space for up to 2 characters produced in a loop.
19604 (decode_coding_iso_2022): Abort if there isn't enough place in
19605 charbuf for the composition carryover bytes.
19607 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19609 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19610 aborting when %lld or %lll format is passed.
19611 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19612 %llo or %llx format is passed. (Bug#8545)
19614 * window.c (window_scroll_line_based): Use a marker instead of
19615 simple variables to record original value of point. (Bug#7952)
19617 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19618 produced by %s or %c overflows available buffer space. (Bug#8545)
19620 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19622 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19623 (SIZE_MAX): Move defn after all includes, as they might #define it.
19625 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19627 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19629 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19631 * keyboard.c (Qdelayed_warnings_hook): Define.
19632 (command_loop_1): Run `delayed-warnings-hook'
19633 if Vdelayed_warnings_list is non-nil.
19634 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19635 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19637 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19639 * doprnt.c (doprnt): Don't return value smaller than the buffer
19640 size if the message was truncated. (Bug#8545).
19642 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19644 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19645 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19647 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19649 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19651 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19653 * makefile.w32-in: Update dependencies.
19655 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19657 Improve `doprnt' and its usage. (Bug#8545)
19658 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19659 `format_end'. Remove support for %l as a conversion specifier.
19660 Don't use xrealloc. Improve diagnostics when the %l size modifier
19661 is used. Update the commentary.
19663 * eval.c (verror): Simplify calculation of size_t.
19665 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19668 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19670 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19673 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19675 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19676 This makes this file independent of the recent pseudovector change.
19678 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19680 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19682 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19683 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19684 Remove unused local.
19685 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19687 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19688 GCC 4.6.0 optimizes based on type-based alias analysis.
19689 For example, if b is of type struct buffer * and v of type struct
19690 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19691 != &v->size, and therefore "v->size = 1; b->size = 2; return
19692 v->size;" must therefore return 1. This assumption is incorrect
19693 for Emacs, since it type-puns struct Lisp_Vector * with many other
19694 types. To fix this problem, this patch adds a new type struct
19695 vectorlike_header that documents the constraints on layout of vectors
19696 and pseudovectors, and helps optimizing compilers not get fooled
19697 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19698 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19699 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19701 (XSETPVECTYPE): Rewrite in terms of new macro.
19702 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19703 This is a bit clearer, and further avoids the possibility of
19704 undesirable aliasing.
19705 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19706 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19707 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19708 since Lisp_Subr is a special case (no "next" field).
19709 (ASIZE): Now uses header.size rather than size.
19710 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19711 to avoid the hassle of writing XVECTOR (foo)->header.size.
19712 (struct vectorlike_header): New type.
19713 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19714 object, to help avoid aliasing.
19715 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19716 (SUBRP): Likewise, since Lisp_Subr is a special case.
19717 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19718 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19719 (struct Lisp_Hash_Table): Combine first two members into a single
19720 struct vectorlike_header member. All uses of "size" and "next" members
19721 changed to be "header.size" and "header.next".
19722 * buffer.h (struct buffer): Likewise.
19723 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19724 * frame.h (struct frame): Likewise.
19725 * process.h (struct Lisp_Process): Likewise.
19726 * termhooks.h (struct terminal): Likewise.
19727 * window.c (struct save_window_data, struct saved_window): Likewise.
19728 * window.h (struct window): Likewise.
19729 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19730 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19731 * buffer.c (init_buffer_once): Likewise.
19732 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19734 * process.c (Fformat_network_address): Use local var for size,
19737 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19739 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19740 * data.c (atof): Remove decl; no longer used or needed.
19741 (digit_to_number): Move to lread.c.
19742 (Fstring_to_number): Use new string_to_number function, to be
19743 consistent with how the Lisp reader treats infinities and NaNs.
19744 Do not assume that floating-point numbers represent EMACS_INT
19745 without losing information; this is not true on most 64-bit hosts.
19746 Avoid double-rounding errors, by insisting on integers when
19747 parsing non-base-10 numbers, as the documentation specifies.
19748 * lisp.h (string_to_number): New decl, replacing ...
19749 (isfloat_string): Remove.
19750 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19751 (read1): Do not accept +. and -. as integers; this
19752 appears to have been a coding error. Similarly, do not accept
19753 strings like +-1e0 as floating point numbers. Do not report
19754 overflow for integer overflows unless the base is not 10 which
19755 means we have no simple and reliable way to continue.
19756 Break out the floating-point parsing into a new
19757 function string_to_number, so that Fstring_to_number parses
19758 floating point numbers consistently with the Lisp reader.
19759 (digit_to_number): Move here from data.c. Make it static inline.
19760 (E_CHAR, EXP_INT): Remove, replacing with ...
19761 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19762 (string_to_number): New function, replacing isfloat_string.
19763 This function checks for valid syntax and produces the resulting
19764 Lisp float number too. Rework it so that string-to-number
19765 no longer mishandles examples like "1.0e+". Use strtoumax,
19766 so that overflow for non-base-10 numbers is reported only when
19767 there's no portable and simple way to convert to floating point.
19769 * textprop.c (set_text_properties_1): Rewrite for clarity,
19770 and to avoid GCC warning about integer overflow.
19772 * intervals.h (struct interval): Use EMACS_INT for members
19773 where EMACS_UINT might cause problems. See
19774 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19775 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19776 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19778 (offset_intervals): Tell GCC not to worry about length overflow
19779 when negating a negative length.
19781 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19782 (overrun_check_free): Likewise.
19784 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19785 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19788 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19789 (gnutls_make_error): Rename local to avoid shadowing.
19790 (gnutls_emacs_global_deinit): ifdef out; not used.
19791 (Fgnutls_boot): Use const for pointer to readonly storage.
19792 Comment out unused local. Fix pointer signedness problems.
19794 * lread.c (openp): Don't stuff size_t into an 'int'.
19795 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19796 about possible signed overflow.
19798 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19799 (GDK_KEY_g): Don't define if already defined.
19800 (xg_prepare_tooltip): Avoid pointer signedness problem.
19801 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19803 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19804 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19806 * xfns.c (Fx_window_property): Simplify a bit,
19807 to make a bit faster and to avoid GCC 4.6.0 warning.
19808 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19810 * fns.c (internal_equal): Don't assume size_t fits in int.
19812 * alloc.c (compact_small_strings): Tighten assertion a little.
19814 Replace pEd with more-general pI, and fix some printf arg casts.
19815 * lisp.h (pI): New macro, generalizing old pEd macro to other
19816 conversion specifiers. For example, use "...%"pI"d..." rather
19817 than "...%"pEd"...".
19818 (pEd): Remove. All uses replaced with similar uses of pI.
19819 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19820 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19821 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19822 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19823 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19824 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19825 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19827 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19828 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19829 * print.c (safe_debug_print, print_object): Likewise.
19830 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19832 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19833 avoiding the 0 flag, which is not portable.
19834 * process.c (Fmake_network_process): Use pI to avoid cast.
19835 * region-cache.c (pp_cache): Likewise.
19836 * xdisp.c (decode_mode_spec): Likewise.
19837 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19838 behavior on 64-bit hosts with printf arg.
19839 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19840 (x_stop_queuing_selection_requests): Likewise.
19841 (x_get_window_property): Don't truncate byte count to an 'int'
19844 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19845 here, since it parses constructs like leading '-' and spaces,
19846 which are not wanted; and it overflows with large numbers.
19847 Instead, simply match F[0-9]+, which is what is wanted anyway.
19849 * alloc.c: Remove unportable assumptions about struct layout.
19850 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19851 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19852 (allocate_vectorlike, make_pure_vector): Use the new macros,
19853 plus offsetof, to remove unportable assumptions about struct layout.
19854 These assumptions hold on all porting targets that I know of, but
19855 they are not guaranteed, they're easy to remove, and removing them
19856 makes further changes easier.
19858 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19859 This doesn't fix a bug but makes the code clearer.
19860 (string_overrun_cookie): Now const. Use initializers that
19861 don't formally overflow signed char, to avoid warnings.
19862 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19863 can cause Emacs to crash when string overrun checking is enabled.
19864 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19865 multiple of sizeof (EMACS_INT); it need not be, if
19866 alignof(EMACS_INT) < sizeof (EMACS_INT).
19867 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19869 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19873 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19875 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19876 supposed to be handshaking. (Bug#8556)
19877 Reported by Paul Eggert <eggert@cs.ucla.edu>.

19881 * lisp.h (Qdebug): List symbol.
19882 * eval.c (Qdebug): Restore global linkage.
19883 * keyboard.c (debug-on-event): New variable.
19884 (handle_user_signal): Break into debugger when debug-on-event
19885 matches the current signal symbol.
19887 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19889 * alloc.c (check_sblock, check_string_bytes)
19890 (check_string_free_list): Convert to standard C.
19892 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19894 * w32.c (emacs_gnutls_push): Fix typo.
19896 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19898 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19899 "cast to pointer from integer of different size".
19901 Improve doprnt and its use in verror. (Bug#8545)
19902 * doprnt.c (doprnt): Document the set of format control sequences
19903 supported by the function. Use SAFE_ALLOCA instead of always
19906 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19907 is one byte too soon. Don't use xrealloc; instead xfree and
19910 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19912 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19915 * gnutls.c: Renamed global_initialized to
19916 gnutls_global_initialized. Added internals for the
19917 :verify-hostname-error, :verify-error, and :verify-flags
19918 parameters of `gnutls-boot' and documented those parameters in the
19919 docstring. Start callback support.
19920 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19921 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19922 on error. Return error code.
19923 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19924 (emacs_gnutls_read): Likewise.
19925 (Fgnutls_boot): Return handshake error code.
19926 (emacs_gnutls_handle_error): New function.
19927 (wsaerror_to_errno): Likewise.
19929 * w32.h (emacs_gnutls_pull): Add prototype.
19930 (emacs_gnutls_push): Likewise.
19932 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
19933 (emacs_gnutls_push): Likewise.
19935 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19937 * process.c (wait_reading_process_output): Check if GnuTLS
19938 buffered some data internally if no FDs are set for TLS
19941 * makefile.w32-in (OBJ2): Add gnutls.$(O).
19942 (LIBS): Link to USER_LIBS.

19947 * xdisp.c (handle_single_display_spec): Rename the
19948 display_replaced_before_p argument into display_replaced_p, to
19949 make it consistent with the commentary. Fix typos in the
19952 * textprop.c (syms_of_textprop): Remove dead code.

20445 * font.h (font_close_object): Remove.
20446 * fontset.c (FONTSET_OBJLIST): Remove.
20447 (free_realized_fontset) #if-0 the body, which does nothing.
20448 (face_suitable_for_char_p): #if-0, as it's never called.
20449 * fontset.h (face_suitable_for_char_p): Remove decl.
20450 * xfaces.c (face_at_string_position):
20451 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
20452 since 0 is always ASCII.
20454 * fns.c (weak_hash_tables): Now static.
20456 * fileio.c: Make symbols static if they're not exported.
20457 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

20471 * lisp.h (fatal_error_signal_hook): Remove decl.
20472 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.

20475 * editfns.c, lisp.h (get_operating_system_release): Remove.
20476 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20477 worth the hassle of breaking this out.
20479 * xterm.c: Make symbols static if they're not exported.
20480 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
20481 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

20583 * buffer.c (buffer_count): Remove unused var.
20585 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

20592 * atimer.h (run_all_atimers): Remove; not exported.
20594 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20595 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20596 was inaccessible from Lisp.
20597 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20598 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20600 alloc.c: Import and export fewer symbols, and remove unused items.
20601 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20603 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20604 it's not optimized away by whole-program optimization.

20606 (catchlist, handlerlist, mark_backtrace):
20607 Declare only if BYTE_MARK_STACK.

20616 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20617 (mark_backtrace): Define only if BYTE_MARK_STACK.
20618 * xdisp.c (message_enable_multibyte): Now static.
20620 Declare Lisp_Object Q* variables to be 'static' if not exported.
20621 This makes it easier for human readers (and static analyzers)
20622 to see whether these variables are used from other modules.
20623 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20624 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

20633 Remove decls of unexported vars.
20634 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20636 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20638 Make Emacs functions such as Fatom 'static' by default.
20639 This makes it easier for human readers (and static analyzers)
20640 to see whether these functions can be called from other modules.
20641 DEFUN now defines a static function. To make the function external
20642 so that it can be used in other C modules, use the new macro DEFUE.
20643 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20644 (Finit_image_library):
20645 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20646 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20647 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20648 Remove decls, since these functions are now static.
20649 (Funintern, Fget_internal_run_time): New decls, since these functions
20650 were already external.
20652 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20653 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20660 Mark functions with DEFUE instead of DEFUN,
20661 if they are used in other modules.
20662 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20663 decls for now-static functions.
20664 * buffer.h (Fdelete_overlay): Remove decl.
20665 * callproc.c (Fgetenv_internal): Mark as internal.

20674 * image.c (Finit_image_library): New forward static decl.
20675 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20676 * intervals.h (Fprevious_property_change):
20677 (Fremove_list_of_text_properties): Remove decls.
20678 * keyboard.c (Fthis_command_keys): Remove decl.
20679 (Fcommand_execute): New forward static decl.

20695 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
20697 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20700 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20702 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20703 when at ZV. (Bug#8487)
20705 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20707 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20710 * sound.c (sound_cleanup, alsa_close): Likewise.
20711 * termcap.c (tgetent): Likewise.
20712 * xfns.c (x_default_font_parameter): Likewise.
20713 * xsettings.c (read_and_apply_settings): Likewise.
20715 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20716 (overrun_check_free): Protoize.
20718 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20720 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20721 since callers should never pass a negative size.
20722 Change the signature to match that of plain 'read' and 'write'; see
20723 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20724 * lisp.h: Update prototypes of emacs_write and emacs_read.
20726 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20728 * xdisp.c (redisplay_window): Don't try to determine the character
20729 position of the scroll margin if the window start point w->startp
20730 is outside the buffer's accessible region. (Bug#8468)
20732 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20734 Fix write-region and its subroutines for buffers > 2GB.
20735 * fileio.c (a_write, e_write): Modify declaration of arguments and
20736 local variables to support buffers larger than 2GB.
20737 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20739 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20740 argument, local variables, and return value.
20742 * lisp.h: Update prototypes of emacs_write and emacs_read.
20744 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20746 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20748 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20750 Fix more problems found by GCC 4.6.0's static checks.
20752 * xdisp.c (vmessage): Use a better test for character truncation.
20754 * charset.c (load_charset_map): <, not <=, for optimization,
20755 and to avoid potential problems with integer overflow.
20756 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20757 * casetab.c (set_identity, shuffle): Likewise.
20758 * editfns.c (Fformat): Likewise.
20759 * syntax.c (skip_chars): Likewise.
20761 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20762 This also lets GCC 4.6.0 generate slightly better loop code.
20764 * callint.c (Fcall_interactively): <, not <=, for optimization.
20765 (Fcall_interactively): Count the number of arguments produced,
20766 not the number of arguments given. This is simpler and lets GCC
20767 4.6.0 generate slightly better code.
20769 * ftfont.c: Distingish more carefully between FcChar8 and char.
20770 The previous code passed unsigned char * to a functions like
20771 strlen and xstrcasecmp that expect char *, which does not
20772 conform to the C standard.
20773 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20774 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20775 char * when the C standard requires it.
20777 * keyboard.c (read_char): Remove unused var.
20779 * eval.c: Port to Windows vsnprintf (Bug#8435).
20780 Include <limits.h>.
20781 (SIZE_MAX): Define if the headers do not.
20782 (verror): Do not give up if vsnprintf returns a negative count.
20783 Instead, grow the buffer. This ports to Windows vsnprintf, which
20784 does not conform to C99. Problem reported by Eli Zaretskii.
20785 Also, simplify the allocation scheme, by avoiding the need for
20786 calling realloc, and removing the ALLOCATED variable.
20788 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20790 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20791 But keep the doprint source code for now, as we might revamp it
20792 and use it again (Bug#8435).
20793 * lisp.h (doprnt): Remove.
20794 * Makefile.in (base_obj): Remove doprnt.o.
20795 * deps.mk (doprnt.o): Remove.
20797 error: Print 32- and 64-bit integers portably (Bug#8435).
20798 Without this change, on typical 64-bit hosts error ("...%d...", N)
20799 was used to print both 32- and 64-bit integers N, which relied on
20800 undefined behavior.
20801 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20802 * lisp.h (error, verror): Mark as printf-like functions.
20803 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20804 Report overflow in size calculations when allocating printf buffer.
20805 Do not truncate output string at its first null byte.
20806 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20807 Truncate the output at a character boundary, since vsnprintf does not
20809 * charset.c (check_iso_charset_parameter): Convert internal
20810 character to string before calling 'error', since %c now has the
20812 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20813 overflow when computing char to be passed to 'error'. Do not
20814 pass Lisp_Object to 'error'; pass the integer instead.
20815 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20816 formatted with plain %d.
20818 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20820 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20822 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20824 * xterm.c (x_catch_errors): Remove duplicate declaration.
20826 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20828 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20830 2011-04-10 Jim Meyering <meyering@redhat.com>
20832 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20833 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20834 return ssize_t not "int", and use size_t as the buffer length.
20835 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20836 * gnutls.h: Update declarations.
20837 * process.c (read_process_output): Use ssize_t, to match.
20838 (send_process): Likewise.
20840 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20842 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20844 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20846 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20847 Use unsigned char, to match FcChar8 type definition.
20849 * xterm.c (handle_one_xevent):
20850 * xmenu.c (create_and_show_popup_menu):
20851 * xselect.c (x_decline_selection_request)
20852 (x_reply_selection_request): Avoid type-punned deref of X events.
20854 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20856 Fix some uses of `int' instead of EMACS_INT.
20857 * search.c (string_match_1, fast_string_match)
20858 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20859 (scan_buffer, find_next_newline_no_quit)
20860 (find_before_next_newline, search_command, Freplace_match)
20861 (Fmatch_data): Make some `int' variables be EMACS_INT.
20863 * xdisp.c (display_count_lines): 3rd argument and return value now
20864 EMACS_INT. All callers changed.
20865 (pint2hrstr): Last argument is now EMACS_INT.

20883 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20884 (encode_invocation_designation): Last argument P_NCHARS is now
20886 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20887 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

20910 instead of using internal_with_output_to_temp_buffer.
20911 (Qhelp_form_show): New var.
20912 (syms_of_keyboard): Use DEFSYM macro.
20914 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20950 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20952 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20953 This avoids several warnings with gcc -Wstrict-overflow.
20954 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20955 directly, rather than having caller test rule sign. This avoids
20956 some unnecessary tests.
20957 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20958 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20959 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20961 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20962 (xfont_open): Avoid unnecessary tests.
20964 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20966 * composite.h, composite.c (composition_gstring_put_cache):
20967 Use EMACS_INT, not int, for length.
20969 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20970 breaking out part of COMPOSITION_DECODE_RULE.
20971 (COMPOSITION_DECODE_RULE): Use it.
20972 * composite.c (get_composition_id): Remove unused local vars,
20973 by using the new macro.
20975 * textprop.c (set_text_properties_1): Change while to do-while,
20976 since the condition is always true at first.
20978 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20979 (interval_deletion_adjustment): Return unsigned value.
20982 * process.c (list_processes_1, create_pty, read_process_output):
20983 (exec_sentinel): Remove vars that were set but not used.
20984 (create_pty): Remove unnecessary "volatile"s.
20985 (Fnetwork_interface_info): Avoid possibility of int overflow.

20998 * print.c (print_error_message): Avoid int overflow.
21000 * font.c (font_list_entities): Redo for clarity,
21001 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21003 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21004 (font_score): Avoid potential overflow in diff calculation.

21007 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21009 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21011 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21012 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21013 can always succeed if overflow has undefined behavior.
21015 * search.c (boyer_moore, wordify): Remove vars set but not used.
21016 (wordify): Omit three unnecessary tests.
21018 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21019 All callers changed. This avoids the need for an unused var.
21021 * casefiddle.c (casify_region): Remove var that is set but not used.
21023 * dired.c (file_name_completion): Remove var that is set but not used.
21025 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21027 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21028 (Finsert_file_contents): Remove unnecessary code checking fd.
21030 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21031 Check for integer overflow on size calculations.
21033 * buffer.c (Fprevious_overlay_change): Remove var that is set
21036 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21037 Remove vars that are set but not used.
21038 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21039 (timer_check_2): Mark vars as initialized.
21041 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21043 * image.c (lookup_image): Remove var that is set but not used.
21044 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21046 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21047 that are set but not used.
21049 * xfns.c (make_invisible_cursor): Don't return garbage
21050 if XCreateBitmapFromData fails (Bug#8410).
21052 * xselect.c (x_get_local_selection, x_handle_property_notify):
21053 Remove vars that are set but not used.
21055 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21056 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21058 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21059 Remove var that is set but not used.
21060 (scroll_bar_windows_size): Now size_t, not int.
21061 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21062 Check for overflow.
21064 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21065 (map_tty_color) [!defined MSDOS]: Likewise.
21067 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21069 * coding.c: Remove vars that are set but not used.
21070 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21071 All callers changed.
21072 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21073 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21074 (decode_coding_charset): Remove vars that are set but not used.
21076 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21077 that is set but not used.
21079 * print.c (print_object): Remove var that is set but not used.
21081 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21082 The gnulib version avoids calling malloc in the usual case,
21083 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21084 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21085 * filelock.c (current_lock_owner): Likewise.
21086 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21087 * sysdep.c: Include allocator.h, careadlinkat.h.
21088 (emacs_no_realloc_allocator): New static constant.
21089 (emacs_readlink): New function.
21090 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21091 ../lib/careadlinkat.h.
21093 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21095 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21096 first non-nil return value).
21098 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21100 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21101 if not defined (Bug#8403).
21103 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21105 * xdisp.c (display_count_lines): Remove parameter `start',
21106 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21107 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21108 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21110 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21111 and thereabouts. All callers changed.
21112 (get_per_char_metric): Remove parameter `f', unused since
21113 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21115 2011-04-02 Jim Meyering <meyering@redhat.com>
21117 do not dereference NULL upon failed strdup
21118 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21119 (ns_get_family): Likewise.
21121 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21123 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21125 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21127 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21130 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21132 Add lexical binding.
21134 * window.c (Ftemp_output_buffer_show): New fun.
21135 (Fsave_window_excursion):
21136 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21138 * lread.c (lisp_file_lexically_bound_p): New function.
21139 (Fload): Bind Qlexical_binding.
21140 (readevalloop): Remove `evalfun' arg.
21141 Bind Qinternal_interpreter_environment.
21142 (Feval_buffer): Bind Qlexical_binding.
21143 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21145 (syms_of_lread): Declare `lexical-binding'.
21147 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21149 * keyboard.c (eval_dyn): New fun.
21150 (menu_item_eval_property): Use it.
21152 * image.c (parse_image_spec): Use Ffunctionp.
21154 * fns.c (concat, mapcar1): Accept byte-code-functions.
21156 * eval.c (Fsetq): Handle lexical vars.
21157 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21158 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21159 (FletX, Flet): Obey lexical binding.
21160 (Fcommandp): Handle closures.
21161 (Feval): New `lexical' arg.
21162 (eval_sub): New function extracted from Feval. Use it almost
21163 everywhere where Feval was used. Look up vars in lexical env.
21165 (Ffunctionp): Move from subr.el.
21166 (Ffuncall): Handle closures.
21167 (apply_lambda): Remove `eval_flags'.
21168 (funcall_lambda): Handle closures and new byte-code-functions.
21169 (Fspecial_variable_p): New function.
21170 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21171 but without exporting it to Lisp.
21173 * doc.c (Fdocumentation, store_function_docstring):
21174 * data.c (Finteractive_form): Handle closures.
21176 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21179 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21181 (exec_byte_code): New function extracted from Fbyte_code to handle new
21182 calling convention for byte-code-functions. Add new byte-codes.
21184 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21186 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21188 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21190 * xdisp.c (redisplay_internal): Fix prototype.
21192 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21194 * xdisp.c (SCROLL_LIMIT): New macro.
21195 (try_scrolling): Use it when setting scroll_limit.
21196 Limit scrolling to 100 screen lines.
21197 (redisplay_window): Even when falling back on "recentering",
21198 position point in the window according to scroll-conservatively,
21199 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21201 (try_scrolling): When point is above the window, allow searching
21202 as far as scroll_max, or one screenful, to compute vertical
21203 distance from PT to the scroll margin position. This prevents
21204 try_scrolling from unnecessarily failing when
21205 scroll-conservatively is set to a value slightly larger than the
21206 window height. Clean up the case of PT below the margin at bottom
21207 of window: scroll_max can no longer be INT_MAX. When aggressive
21208 scrolling is in use, don't let point enter the opposite scroll
21209 margin as result of the scroll.
21210 (syms_of_xdisp) <scroll-conservatively>: Document the
21211 threshold of 100 lines for never-recentering scrolling.
21213 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21215 * dispextern.h (move_it_by_lines):
21216 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21217 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21218 (message_log_check_duplicate): Remove parameters `prev_bol' and
21219 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21220 (redisplay_internal): Remove parameter `preserve_echo_area',
21221 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21223 * indent.c (Fvertical_motion):
21224 * window.c (window_scroll_pixel_based, Frecenter):
21225 Don't pass `need_y_p' to `move_it_by_lines'.
21227 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21229 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21230 steal a few bits to be more compact.
21231 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21232 Remove unneeded casts.
21234 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21236 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21238 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21239 binding" message (bug#7967).
21241 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21243 Fix more problems found by GCC 4.6.0's static checks.
21245 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21246 Remove unused local var.
21248 * editfns.c (Fmessage_box): Remove unused local var.
21250 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21251 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21252 Omit unused local vars.
21253 * window.c (shrink_windows): Omit unused local var.
21254 * menu.c (digest_single_submenu): Omit unused local var.
21255 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21256 Omit unused local var.
21258 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21259 Don't assume string length fits in int.
21260 (keyremap_step, read_key_sequence): Use size_t for sizes.
21261 (read_key_sequence): Don't check last_real_key_start redundantly.
21263 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21264 instead of alloca (Bug#8344).
21266 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21267 (Fbacktrace_frame): Don't assume nframes fits in int.
21269 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21271 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21274 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21276 * cm.c (calccost): Turn while-do into do-while, for clarity.
21278 * keyboard.c (syms_of_keyboard): Use the same style as later
21279 in this function when indexing through an array. This also
21280 works around GCC bug 48267.
21282 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21284 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21286 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21287 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21289 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21290 This avoids undefined behavior on integer overflow, and is a bit
21291 more convenient anyway since it is compared to a size_t variable.
21293 Variadic C functions now count arguments with size_t, not int.
21294 This avoids an unnecessary limitation on 64-bit machines, which
21295 caused (substring ...) to crash on large vectors (Bug#8344).
21296 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21297 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21298 All variadic functions and their callers changed accordingly.

21304 (funcall_lambda, mark_backtrace): Likewise.
21305 * fns.c (concat): Likewise.
21306 * frame.c (x_set_frame_parameters): Likewise.
21307 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21308 0 if not found, not -1. All callers changed.
21310 * alloc.c (garbage_collect): Don't assume stack size fits in int.

21518 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21520 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21521 unconditionally since it does the check itself.
21523 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21525 Fix more problems found by GCC 4.5.2's static checks.
21527 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21528 the first time through the loop, since we know p0 < p1 then.
21529 This also avoids a gcc -Wstrict-overflow warning.
21531 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21532 leading to a memory leak, possible in functions like
21533 load_charset_map_from_file that can allocate an unbounded number
21534 of objects (Bug#8318).
21536 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21537 that could (at least in theory) be that large.
21539 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21540 This is less likely to overflow, and avoids undefined behavior if
21541 overflow does occur. All callers changed. Use strtoul to scan
21542 for the unsigned long integer.

21559 * process.c (Fmake_network_process): Use socklen_t, not int,
21560 where POSIX says socklen_t is required in portable programs.
21561 This fixes a porting bug on hosts like 64-bit HP-UX, where
21562 socklen_t is wider than int (Bug#8277).
21563 (Fmake_network_process, server_accept_connection):
21564 (wait_reading_process_output, read_process_output):
21567 * process.c: Rename or move locals to avoid shadowing.

21579 Include tparam.h instead, since it declares them.
21580 * cm.h (PC): Remove extern decl; tparam.h now does this.
21581 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21582 * terminfo.c: Include tparam.h, to check interfaces.
21583 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21584 (tparam): Adjust signature to match interface in tparam.h;
21585 this removes some undefined behavior. Check that outstring and len
21586 are zero, which they always are with Emacs.
21587 * tparam.h (PC, BC, UP): New extern decls.
21589 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21590 (xftfont_open): Rename locals to avoid shadowing.

21629 Fix pointer signedness.
21630 (alsa_choose_format): Remove unused local var.
21631 (wav_play): Initialize a variable to 0, to prevent undefined
21632 behavior (Bug#8278).
21634 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21636 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21638 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21639 clobbering (Bug#8298).
21640 * sysdep.c (sys_subshell): Likewise.
21641 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21643 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21644 This should get cleaned up, so that child_setup has the
21645 same signature on all platforms.
21647 * callproc.c (call_process_cleanup): Now static.
21648 (relocate_fd): Rename locals to avoid shadowing.
21650 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21652 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21653 not to be necessary, and produces flickering.
21655 2011-03-20 Glenn Morris <rgm@gnu.org>
21657 * config.in: Remove file.
21659 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21704 Define only if needed.
21706 * unexelf.c (unexec): Name an expression,
21707 to avoid gcc -Wbad-function-cast warning.
21708 Use a different way to cause a compilation error if anyone uses
21709 n rather than nn, a way that does not involve shadowing.
21710 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21712 * deps.mk (unexalpha.o): Remove; unused.

21777 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21778 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21779 some of which prompt warnings from gcc -Wbad-function-cast.
21780 (Fformat_time_string, Fencode_time, Finsert_char):
21781 (Ftranslate_region_internal, Fformat):

21809 (Fmemory_limit): Cast sbrk's returned value to char *.
21811 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21812 avoids undefined behavior in theory.
21814 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21816 Use functions, not macros, for up- and down-casing (Bug#8254).
21817 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21818 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21819 to use the following functions instead of these macros.
21820 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21821 EMACS_INT, since callers assume the returned value fits in int.
21822 (upcase1): Likewise, for UPCASE_TABLE.
21823 (uppercasep, lowercasep, upcase): New static inline functions.
21824 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21834 (regex_compile, re_match_2_internal): Mark locals as initialized.
21835 (RETALLOC_IF): Define only if needed.
21836 (WORDCHAR_P): Likewise. This one is never needed, but is used
21837 only in a comment talking about a compiler bug, so put inside
21838 the #if 0 of that comment.
21839 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21840 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21866 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21867 New macros, so that the caller can use some names other than
21868 gcpro1, gcpro2, etc.
21869 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21871 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21872 argument, for consistency with GCPRO2_VAR, etc: it is now the
21873 prefix of the variable, not the variable itself. All uses
21875 * dired.c (directory_files_internal, file_name_completion):
21876 Rename locals to avoid shadowing.
21878 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21879 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21880 dired.c's scmp function, had undefined behavior.
21881 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21882 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21883 * buffer.h: ... to here, because these macros use current_buffer,
21884 and the new implementation with inline functions needs to have
21885 current_buffer in scope now, rather than later when the macros
21887 (downcase, upcase1): New static inline functions.
21888 (DOWNCASE, UPCASE1): Reimplement using these functions.
21889 This avoids undefined behavior in expressions like
21890 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21891 from race conditions in accessing the global variables
21892 case_temp1 and case_temp2.
21893 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21894 * lisp.h (case_temp1, case_temp2): Remove their decls.
21895 * character.h (ASCII_CHAR_P): Move from here ...
21896 * lisp.h: ... to here, so that the inline functions mentioned
21897 above can use them.
21899 * dired.c (directory_files_internal_unwind): Now static.
21901 * fileio.c (file_name_as_directory, directory_file_name):

21904 (file_name_as_directory): Use const pointers when appropriate.
21905 (Fexpand_file_name): Likewise. In particular, newdir might
21906 point at constant storage, so make it a const pointer.
21907 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21908 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21910 (Fset_file_times, Finsert_file_contents, auto_save_error):

21915 to avoid shadowing.
21917 * marker.c (bytepos_to_charpos): Remove; unused.
21919 * lisp.h (verify_bytepos, count_markers): New decls,
21920 so that gcc does not warn that these functions aren't declared.
21922 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21923 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21924 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21925 (copy_text): Remove unused local var.
21927 * filelock.c (within_one_second): Now static.
21928 (lock_file_1): Rename local to avoid shadowing.
21930 * buffer.c (fix_overlays_before): Mark locals as initialized.
21931 (fix_start_end_in_overlays): Likewise. This function should be
21932 simplified by using pointers-to-pointers, but that's a different
21934 (switch_to_buffer_1): Now static.
21935 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21936 (report_overlay_modification): Rename locals to avoid shadowing.

21941 to suppress a gcc -Wclobbered warning that does not seem to be right.
21942 (MAXPATHLEN): Define only if needed.
21944 * process.c (serial_open, serial_configure): Move decls from here ...
21945 * systty.h: ... to here, so that they can be checked.
21947 * fns.c (get_random, seed_random): Move extern decls from here ...
21948 * lisp.h: ... to here, so that they can be checked.
21950 * sysdep.c (reset_io): Now static.

21959 (describe_map_tree):
21960 Rename locals to avoid shadowing.

22110 1152921504606846976) returns the obviously-bogus value (-948597
22111 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22112 reports time overflow. See
