24 unconditionally. (Bug#9066)
26 * w32.c (set_errno): Reset h_errno and don't set it to any other

74 Fix AIX port (Bug#13650).
75 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
76 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
77 was #undeffed earlier, so it cannot be used as a macro here.
78 Use the constant and not the macro.
80 2013-02-15 Eli Zaretskii <eliz@gnu.org>
82 * w32proc.c (new_child): If no vacant slots are found in

114 2013-02-13 Glenn Morris <rgm@gnu.org>
116 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
118 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
120 Improve AIX port some more (Bug#13650).
121 With this, it should be as good as it was in 23.3, though it's
122 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
123 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
124 * unexaix.c (start_of_text): Remove.
125 (_data, _text): Declare as char[], not int, as AIX manual suggests.
126 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
127 (orig_load_scnptr, orig_data_scnptr):
128 Now off_t, not long, since they are file offsets.
129 (make_hdr): Use _data, not start_of_data ().
130 This is the key part of the fix.
131 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
132 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
134 * pre-crt0.c (data_start): Initialize to 1.
135 This ports to compilers that optimize the external declaration
136 'int x = 0;' as if it were 'int x;' to shrink the executable.
138 Improve AIX port (Bug#13650).
139 This doesn't fix the bug, but it makes progress: Emacs builds now.
140 * unexaix.c: Include inttypes.h, stdarg.h.
141 (report_error, report_error_1): Mark as _Noreturn.
142 (report_error): Don't report the wrong errno.
143 (report_error_1): Now varargs. All callers changed.
144 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
145 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
146 (write_ptr): Use %p to print address rather than %lx and a cast
147 to unsigned long. Grow buffer a bit, to be safer.
149 2013-02-13 Eli Zaretskii <eliz@gnu.org>
151 * bidi.c (bidi_resolve_neutral): After finding the next
152 non-neutral character, accept NEUTRAL_ON type as well, because
153 directional control characters, such as LRE and RLE, have their
154 type converted to that by bidi_resolve_weak. This avoids aborts
155 when LRE/RLE follows a run of neutrals.
156 (bidi_move_to_visually_next): Assert that return value of
157 bidi_peek_at_next_level is non-negative. Negative values will

165 * callproc.c (init_callproc):
166 * dispnew.c (init_display):
167 * sysdep.c (sys_subshell):
168 Omit unnecessary cast of getenv or egetenv.

172 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
175 2013-02-12 Eli Zaretskii <eliz@gnu.org>
177 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
179 (display_line): Set w->region_showing to the value of
180 it->region_beg_charpos, not to -1. This fixes redisplay
181 optimization when cursor is moved up after M->. (Bug#13623)
183 (try_scrolling): Scroll text up more if point is too close to ZV
184 and inside the scroll margin. This makes sure point is moved
185 outside the scroll margin in these cases.
187 * window.h (struct window): region_showing can no longer be
190 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
192 Tune by using memchr and memrchr.
193 * doc.c (Fsnarf_documentation):
194 * fileio.c (Fsubstitute_in_file_name):
195 * search.c (find_newline, scan_newline):
196 * xdisp.c (pos_visible_p, display_count_lines):
197 Use memchr and memrchr rather than scanning byte-by-byte.
198 * search.c (find_newline): Rename from scan_buffer.
199 Omit first arg TARGET, as it's always '\n'. All callers changed.
201 Clean up read_key_sequence a tiny bit more.
202 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
203 (read_key_sequence): Remove unused locals.
205 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
207 Clean up read_key_sequence a bit; reread active keymaps after first event.
208 * keyboard.c (read_char, read_char_x_menu_prompt)
209 (read_char_minibuf_menu_prompt):
210 Replace nmaps+maps with a single `map' arg.
211 (follow_key): Operate on a single map.
212 (active_maps): New function.
213 (test_undefined): Also return true for nil bindings.
214 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
215 a single (composed) keymap. Remember `first_event' to choose the right
216 set of active keymaps. Recompute the set of keymaps after receiving
217 the first event. Remove GOBBLE_FIRST_EVENT.
218 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
219 * keyboard.h (read_char): Update declaration.
220 * lread.c (read_filtered_event): Adjust call to read_char.
222 2013-02-11 Eli Zaretskii <eliz@gnu.org>
224 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
225 Don't use the limitation on backwards movement when lines are truncated
226 in the window. (Bug#13675)
228 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
230 * marker.c (set_marker_internal): If desired position is passed
231 as a marker, avoid call to buf_charpos_to_bytepos.
232 * window.c (Fset_window_point): Omit redundant type checking.
233 (Fset_window_start): Likewise. Format comment.
234 (window_scroll_pixel_based): Use set_marker_restricted_both
235 with character and byte positions obtained from an iterator.
236 (Fset_window_configuration): Use set_marker_restricted_both.
237 * xdisp.c (message_dolog): Likewise.
239 2013-02-10 Eli Zaretskii <eliz@gnu.org>
241 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
242 When text lines are longer than window's screen lines, don't move back
243 too far. This speeds up some redisplay operations. (Bug#13675)
245 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
247 * syntax.c (scan_sexps_forward): Fix byte position calculation
248 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
250 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
252 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
255 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
257 Minor hashing refactoring.
258 * fns.c (SXHASH_REDUCE): Move to lisp.h.
259 (sxhash_float): Return EMACS_UINT, for consistency with the other
261 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
262 non-static inline function and therefore can't use static vars.
263 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
264 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
265 with the other hash functions.
267 2013-02-09 Eli Zaretskii <eliz@gnu.org>
269 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
270 XXXXXX part of the temporary file pattern is not downcased even
271 when w32-downcase-file-names is non-nil. (Bug#13661)
273 * xdisp.c (decode_mode_spec): Remove handling of %t.
275 * msdos.c (careadlinkatcwd): Remove.
277 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
279 * lread.c (skip_dyn_bytes): New function (bug#12598).

281 (load_each_byte): Remove. Update users.
283 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
285 * search.c (scan_buffer): Calculate end byte position just once.
286 (scan_newline): Do not recalculate start_byte.
287 (search_command): Use eassert.
288 * syntax.c (struct lisp_parse_state): New member location_byte.
289 (scan_sexps_forward): Record from_byte and avoid redundant
290 character to byte position calculation ...
291 (Fparse_partial_sexp): ... here. Break too long line.
293 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>

312 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
314 * coding.c (Fdefine_coding_system_internal): Use AREF where
315 argument is known to be a vector.
316 * fns.c (Flocale_info): Likewise for ASET.
317 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
318 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
320 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
322 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
325 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
326 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
327 updateCollectionBehaviour.
329 * nsterm.m (NEW_STYLE_FS): Remove.
330 (ns_last_use_native_fullscreen): New variable.
331 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
332 (x_set_window_size): Do not take title bar and tool bar into account
333 if isFullscreen returns YES.
334 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
335 (check_native_fs): New function.
336 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
337 (ns_term_init): Remove NEW_STYLE_FS.
338 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
339 and tool bar if isFullscreen returns NO.
340 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
341 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
343 (window:willUseFullScreenPresentationOptions:): New method.
344 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
345 Hide toolbar if not enabled (Bug#13444).
346 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
347 Restore tool bar if enabled, hide it otherwise (Bug#13444).
348 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
349 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
350 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
351 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
352 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
353 (syms_of_nsterm): Add ns-use-native-fullscreen.
355 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
357 * fileio.c (Qchoose_write_coding_system): Now static.
359 2013-02-04 Eli Zaretskii <eliz@gnu.org>
361 * xdisp.c (window_buffer_changed): region_showing can be negative,
362 which still means region is being displayed.
363 (redisplay_internal): Resurrect code that forced redisplay of the
364 whole window when showing region and the mark has changed.
365 Record the new mark position to allow redisplay optimizations.
366 (display_line): If it->region_beg_charpos is non-zero, set the
367 window's region_showing member to -1. (Bug#13623) (Bug#13626)
369 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
370 not bitfield of 1 bit.
372 2013-02-03 Daniel Colascione <dancol@dancol.org>
374 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
375 daemon mode works on cygw32 when Emacs is installed and not just
378 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
380 Avoid file time stamp bug on MS-Windows (Bug#13149).
381 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
382 as FAT32 doesn't update time stamps when truncating them.
383 Also, check that a file time stamp is not a multiple of 100 ns;
384 this should catch all instances of the problem on MS-Windows,
385 as its native file system resolution is 100 ns or worse, and
386 checking for a non-multiple of 100 ns should impose only a small
387 overhead on systems with ns resolution.
389 2013-02-02 Eli Zaretskii <eliz@gnu.org>
391 Avoid encoding file names on MS-Windows when they need to be run
392 through dostounix_filename.
393 * w32.c (normalize_filename): Accept an additional argument
394 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
395 downcase it even if w32-downcase-file-names is non-nil.
396 (dostounix_filename): Accept an additional argument MULTIBYTE and
397 pass it to normalize_filename.
398 (emacs_root_dir): Adjust.
400 * msdos.h (dostounix_filename): Adjust prototype.
402 * w32.h (dostounix_filename): Adjust prototype.
404 * msdos.c (dostounix_filename): Accept an additional argument and
406 (init_environment): Adjust callers of dostounix_filename.
408 * fileio.c (Ffile_name_directory, file_name_as_directory)
409 (directory_file_name, Fexpand_file_name)
410 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
412 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
414 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
415 variables, as egetenv is case-insensitive for DOS_NT.
417 * dired.c (file_name_completion): Don't call Fdirectory_file_name
418 with an encoded file name.
420 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
421 Adjust calls to dostounix_filename.
423 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
425 * unexw32.c (unexec): Adjust call to dostounix_filename.
427 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
429 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
432 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
435 * callproc.c (Fcall_process): Make sure program name in PATH and
436 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
437 is passed to exec/spawnve, which fails unless the file-name
440 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
441 even if w32-quote-process-args is nil.
443 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
445 Fix timestamp bug when write-region appends nothing (Bug#13149).
446 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
447 the file's time stamp doesn't change if Emacs happens to write nothing
448 to the file, and on a buggy file system this could cause Emacs to
449 incorrectly infer that the file system doesn't have the bug.
450 Avoid this problem by inhibiting the inference in this case.
452 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
454 * window.h (struct window): Convert base_line_number, base_line_pos
455 and column_number_displayed members from Lisp_Object to ptrdiff_t.
456 Convert region_showing member from Lisp_Object to bitfield.
457 Remove sequence_number member. Adjust comments.
458 * window.c (sequence_number): Remove.
459 (make_window): Initialize column_number_displayed.
460 * print.c (print_object): Follow the printed representation of
461 frames and print window pointer to distinguish between windows.
462 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
463 * xdisp.c (wset_base_line_number, wset_base_line_pos)
464 (wset_column_number_displayed, wset_region_showing): Remove.
465 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
466 (try_scrolling, try_cursor_movement, redisplay_window)
467 (try_window_reusing_current_matrix, try_window_id, display_line)
468 (display_mode_lines, decode_mode_spec): Adjust users.
469 * .gdbinit (pwinx): Do not print sequence_number.
471 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
473 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
474 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
475 * dired.c: Include <fcntl.h>.
476 (open_directory): New function, which uses open and fdopendir
477 rather than opendir. DOS_NT platforms still use opendir, though.
478 (directory_files_internal, file_name_completion): Use it.
479 (file_attributes): New function, with most of the old Ffile_attributes.
480 (directory_files_internal, Ffile_attributes): Use it.
481 (file_attributes, file_name_completion_stat): First arg is now fd,
482 not dir name. All uses changed. Use fstatat rather than lstat +
484 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
485 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
486 (emacs_readlinkat): New function, with much of the old
487 Ffile_symlink_p, but with an fd argument for speed.
488 It uses readlinkat rather than careadlinkatcwd, so that it
489 need not assume the working directory.
490 (Ffile_symlink_p): Use it.
491 * filelock.c (current_lock_owner): Use emacs_readlinkat
492 rather than emacs_readlink.
493 * lisp.h (emacs_readlinkat): New decl.

497 This stuff is moved to fileio.c.
498 * w32.c (fstatat, readlinkat): New functions.
499 (careadlinkat): Don't check that fd == AT_FDCWD.
500 (careadlinkatcwd): Remove; no longer needed.

505 (Fwrite_region): Update for new choose_write_coding_system args.
506 Move the last piece of choose_write_coding_system here. (Bug#13522)
507 (syms_of_fileio): Add choose-write-coding-system.
509 2013-01-30 Eli Zaretskii <eliz@gnu.org>
511 * w32.c (sys_open): Zero out the flags for the new file descriptor.
512 (sys_close): Zero out the flags for the file descriptor before
513 closing it. (Bug#13546)
515 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
516 (logon_network_drive, stat_worker, symlink, chase_symlinks):
517 Use CharNextExA and CharPrevExA to iterate over file names encoded in
520 * w32.c (w32_get_long_filename, init_environment, readlink):
521 Support file names encoded in DBCS codepages.
522 (readlink): Use the current file-name-coding-system, not the ANSI
523 codepage, to decode and handle targets of symlinks.
525 2013-01-28 Eli Zaretskii <eliz@gnu.org>
527 * w32.c (opendir): Now accepts a 'const char *'.
529 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
531 Remove obsolete redisplay code. See the discussion at
532 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
533 * dispnew.c (preemption_period, preemption_next_check): Remove.
534 (Vredisplay_preemption_period): Likewise.
535 (update_frame, update_single_window, update_window, update_frame_1):
536 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
537 used, following the 2012-06-22 change.
539 2013-01-25 Eli Zaretskii <eliz@gnu.org>
541 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
543 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
545 * font.c (num_fonts): Remove the leftover from old
546 debugging code. Adjust comment style here and there.

551 2013-01-25 Eli Zaretskii <eliz@gnu.org>
553 * w32.c (max_filename_mbslen): New function.
554 (normalize_filename, readdir): Use it to detect locales where ANSI
555 encoding of file names uses a double-byte character set (DBCS).
556 If a DBCS encoding is used, advance by characters using
557 CharNextExA, instead of incrementing a 'char *' pointer.
558 Use _mbslwr instead of _strlwr. (Bug#13515)
560 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
561 request of memory reservation to 1.7GB. (Bug#13065)
563 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
565 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
566 at check_extra_latin label. (Bug#13505)
568 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
570 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
571 Avoid redundant calls to strlen.
573 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
575 Drop async_visible and async_iconified fields of struct frame.
576 This is possible because async input is gone; for details, see
577 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
578 * frame.h (struct frame): Remove async_visible and async_iconified
579 members, convert garbaged to unsigned bitfield. Adjust comments.
580 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
581 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
582 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
583 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
584 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
586 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
587 properly. Likewise for obscured.
589 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
592 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
594 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
596 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
597 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
599 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
601 * xdisp.c (message2, message2_nolog): Remove functions.
602 (message3, message3_nolog): Extract nbytes and multibyteness directly
603 from the string. Change all callers.
604 (message3_nolog): Don't set message_enable_multibyte since set_message
605 will reset it anyway.
606 (message1, message1_nolog): Use message3.
607 (vmessage): Use a stack allocated buffer rather than f->message_buf.
608 (with_echo_area_buffer): Remove last two arguments. Update all callers.
609 (set_message): Drop all but the second arg, which has to be a string.
610 (set_message_1): Simplify now that we know that a1 is NULL and the
611 second arg is a string.
612 * frame.h (struct frame): Remove `message_buf' field.
613 Use glyphs_initialized_p instead.
614 (FRAME_MESSAGE_BUF): Remove macro.
615 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
616 * lisp.h (message2, message2_nolog): Remove declarations.
617 (message3, message3_nolog): Update declarations.
618 * keyboard.c (read_char_minibuf_menu_text)
619 (read_char_minibuf_menu_width): Remove vars.
620 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
621 to correctly handle multibyte strings.
622 * frame.c (delete_frame): Don't free message_buf any more.
623 * editfns.c (message_text, message_length): Remove vars.
624 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
625 * fileio.c (auto_save_error): Use message3 instead of message2.
626 * dispnew.c (adjust_frame_message_buffer): Remove function.
628 2013-01-23 Eli Zaretskii <eliz@gnu.org>
630 * w32term.c (w32fullscreen_hook): Account correctly for the screen
631 real estate used for the tool bar and the menu bar.
633 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
635 * insdel.c (prepare_to_modify_buffer): Force redisplay if
636 hidden buffer is prepared to modification (Bug#13164).
638 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
640 * window.h (struct window): Change window_end_valid member from
641 Lisp_Object to a bitfield. Adjust comments.
642 (wset_window_end_valid): Remove.
643 * window.c (adjust_window_count): Clear window_end_valid.
644 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
645 (Fwindow_line_height, set_window_buffer, Frecenter)
646 (Fsplit_window_internal, Fdelete_other_windows_internal)
647 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
648 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
649 * xdisp.c (check_window_end, reconsider_clip_changes)
650 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
651 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
652 (find_first_unchanged_at_end_row, try_window_id): Likewise.
654 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
656 * xdisp.c (mark_window_display_accurate): Simplify the loop
657 assuming that the only one of vchild, hchild or buffer window
658 slots is non-nil. Call mark_window_display_accurate_1 for
659 the leaf windows only.
660 (mark_window_display_accurate_1): Always assume leaf window.
663 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
665 * emacs.c (Qkill_emacs_hook): Now static.
667 * fileio.c (Finsert_file_contents): Simplify.
668 Remove unnecessary assignments and tests.
670 2013-01-21 Eli Zaretskii <eliz@gnu.org>
672 * w32.c (acl_set_file): Don't test for errors unless
673 set_file_security returns FALSE. Avoids spurious errors when
676 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
678 * fileio.c (Finsert_file_contents): Revert code introduced at
679 2013-01-18 in favor of the simpler and generally better fix.
680 Save stack space by removing 'buffer' and reusing 'read_buf'
683 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
685 * lisp.h (eabs): Define unconditionally (Bug#13419).
686 The old "#if !defined (eabs)" was an unnecessary revenant of back
687 when this macro was called "abs". Document 'eabs' better.
689 2013-01-19 Glenn Morris <rgm@gnu.org>
691 * fns.c (Frandom): Doc fix.
693 2013-01-19 Eli Zaretskii <eliz@gnu.org>
695 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
696 segfault when there are lots of overlays.
698 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
699 when there are lots of overlays.
700 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
701 for the details and a way to reproduce.
703 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
705 * fileio.c: Use O_APPEND to append.
706 This corresponds better to the natural interpretation of "append",
707 and avoids the need to open the output file twice, or to invoke
708 lseek when APPEND is neither nil nor a number.
709 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
710 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
711 file possibly twice, and lseeking to its end; this avoids the
712 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
713 at the same time: the combination is never needed and apparently
714 it doesn't work with DOS_NT.
716 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
717 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
719 Allow floating-point file offsets.
720 Problem reported by Vitalie Spinu in
721 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
722 * fileio.c (emacs_lseek): Remove.
723 (file_offset): New function.
724 (Finsert_file_contents, Fwrite_region): Use it.
726 2013-01-19 Chong Yidong <cyd@gnu.org>
728 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
729 aborting on Fsignal (Bug#13289).
731 2013-01-19 Eli Zaretskii <eliz@gnu.org>
733 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
734 set_file_security as failure due to insufficient privileges.
735 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
736 (fstat): Return owner and group like 'stat' and 'lstat' do.
738 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
740 Work around bug in CIFS and vboxsf file systems (Bug#13149).
741 The bug was observed on Ubuntu operating inside a virtual machine,
742 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
743 The workaround introduces a race condition on non-buggy hosts,
744 but it's an unlikely race and anyway there's a nearly identical
745 nearby race that can't be fixed.
746 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
748 (Fwrite_region): Test for file system time stamp bug.
749 (init_fileio): New function.
750 * lisp.h (init_fileio): Declare it.
751 * emacs.c (main): Call it.
753 * fileio.c (Finsert_file_contents): Simplify new diagnostic
754 and make it more consistent with other stat-failure diagnostics.
756 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
758 Fix crash when inserting data from non-regular files.
759 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
760 for the error description produced by valgrind.
761 * fileio.c (read_non_regular): Rename to read_contents.
762 Free Lisp_Save_Value object used to pass parameters.
763 (read_non_regular_quit): Rename to read_contents_quit.
764 (Finsert_file_contents): Redesign internal file reading loop to adjust
765 gap and end positions after each read and so help make_gap to work
766 properly. Do not signal an I/O error too early and so do not leave
767 not yet decoded characters in a buffer, which was the reason of
768 redisplay crash. Use list2 to build return value. Adjust comments.
770 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
772 Close a race when statting and reading files (Bug#13149).
773 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
774 This avoids a race if the file is renamed between stat and open.
775 This race is not the problem originally noted in Bug#13149;
776 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
778 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

785 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
786 * alloc.c (format_save_value): Rename to make_save_value.
787 (make_save_pointer): New function.
788 (record_xmalloc): Use make_save_pointer.
789 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
790 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
791 Change users of make_save_value to make_save_pointer.
792 Likewise for format_save_value and make_save_value.
794 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
796 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.

808 (map_keymap_char_table_item): Adjust accordingly.
809 * fileio.c (non_regular_fd, non_regular_inserted)
810 (non_regular_nbytes): Remove.
811 (Finsert_file_contents): Convert trytry to ptrdiff_t.
812 Use format_save_value to pass parameters to read_non_regular.
813 (read_non_regular): Use XSAVE_ macros to extract parameters.
815 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
817 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
819 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
821 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
822 extraction from any Lisp_Save_Value slot. Add type checking.
823 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
824 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
825 * xselect.c: All users changed.
827 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
829 Some convenient bits to deal with Lisp_Save_Values.

844 * dired.c (directory_files_internal_unwind):
845 * fileio.c (do_auto_save_unwind):
846 * gtkutil.c (pop_down_dialog):
847 * keymap.c (map_keymap_char_table_item):
848 * lread.c (load_unwind):
849 * nsmenu.m (pop_down_menu):
850 * print.c (print_object) [GC_MARK_STACK]:
851 * xfns.c (clean_up_file_dialog):
852 * xmenu.c (cleanup_widget_value_tree):
853 Omit casts between XSAVE_POINTER and a pointer type.
855 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
857 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
858 * eval.c (eval_sub): Protect `form' from being GCed before its
859 car and cdr becomes protected with the backtrace entry.
861 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
863 Make Lisp_Save_Value more versatile storage for up to four objects.
864 * lisp.h (toplevel): Enumeration to describe types of saved objects.
865 (struct Lisp_Save_Value): New layout. Adjust comments.

870 * alloc.c (allocate_misc): Now global.
871 (free_misc): Likewise. Adjust comment.
872 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
873 (free_save_value): Likewise.
874 (mark_object): Likewise.
875 * editfns.c (save_excursion_save): Pack everything within
876 Lisp_Save_Value and so avoid xmalloc.
877 (save_excursion_restore): Adjust to match new layout. Use free_misc
878 because we do not allocate extra memory any more. Add eassert.
879 * print.c (print_object): New code to print Lisp_Save_Value. Do not
880 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
881 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
882 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
883 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
885 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

895 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
896 Move handlers here from emacs.c; they were out of place.
898 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
900 * xterm.c (syms_of_xterm): Adjust documentation for
901 scroll-bar-adjust-thumb-portion.

934 Clear tzvalbuf_in_environ if this workaround is in effect.
935 Problem and fix reported by Kazuhiro Ito.

939 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):
940 Fix ambiguous doc string cross-reference(s).
942 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
943 doc string cross-reference(s).
945 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
946 string cross-reference(s).
948 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
950 Avoid unnecessary byte position calculation for the gap movement.
951 Since all users of move_gap do CHAR_TO_BYTE for other purposes
952 anyway, all of them should use move_gap_both instead.
953 * lisp.h (move_gap): Remove prototype.
954 * insdel.c (move_gap): Remove.
955 (move_gap_both): Add eassert.

961 emacsclient -t should not suspend Emacs server (Bug#13387)
962 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
964 * term.c (init_tty): Use them instead of rolling our own code.
965 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
966 switches from 'signal' to 'pthread_sigmask', which is safer in
967 multithreaded applications.
968 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
969 which has already arranged for that.
970 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
971 This is the main part of the bug fix.

983 predicate, which is how it's really used now. Adjust comment.
984 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
985 * buffer.c (buffer_slot_type_mismatch): Remove.
986 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
987 predicate. Adjust comment.
988 (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for
989 fill-column, left-margin, tab-width, buffer-saved-size,
990 left-margin-width, right-margin-width, left-fringe-width,
991 right-fringe-width, scroll-bar-width and buffer-display-count.
992 Use Qstringp for default-directory, buffer-file-name,
993 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
994 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
996 * data.c (store_symval_forwarding): Adjust to call the predicate.
998 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
1000 * w32.c (get_name_and_id, acl_set_file):

1012 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1013 (make_gap_1): New function to adjust the gap of any buffer.
1014 * coding.c (coding_alloc_by_making_gap): Use it.
1015 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1016 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1018 2013-01-08 Juri Linkov <juri@jurta.org>
1020 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
1021 of (supports :underline (:style wave)). (Bug#13000)

1030 * keyboard.c (echo_add_key): Rename from echo_add_char.
1032 2013-01-06 Chong Yidong <cyd@gnu.org>
1034 * keyboard.c (echo_add_char): New function, factored out from
1035 echo_char. Don't add a space if the previous echo string was

1039 trailing dash is properly added.
1041 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1043 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1044 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1045 digits for buffer positions, before misalignment starts.
1046 Display "0" for integer "object" field.
1047 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1048 Display the newline glyph more unambiguously.
1050 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1052 * nsterm.m (ns_draw_underwave):
1053 * w32term.c (w32_draw_underwave):
1054 * xterm.c (x_draw_underwave): Make underwave look more triangular
1055 and also degrade gracefully for small fonts. (Bug#13000)
1057 * nsterm.m (ns_draw_text_decoration):
1058 * w32term.c (x_draw_glyph_string):
1059 * xterm.c (x_draw_glyph_string): Don't use previous underline
1060 thickness and position if previous underline type is underwave.
1062 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1064 * fileio.c (Ffile_acl): Undocument return format.
1066 2013-01-02 Glenn Morris <rgm@gnu.org>
1068 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
1070 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>

1077 * fringe.c (compute_fringe_widths):
1078 * lread.c (read_list):
1079 * minibuf.c (Ftry_completion):
1080 * term.c (tty_ins_del_lines):
1081 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1082 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1084 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1086 * w32.c (unsetenv): Set up the string passed to _putenv
1088 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1089 for the bug this caused.
1091 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1093 * coding.c (Qmac): Now static.
1095 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1097 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1098 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1100 toolbar_is_packed to true.
1101 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
1102 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1103 Show all on TOOLBAR_TOP_WIDGET.
1104 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1105 by TOOLBAR_TOP_WIDGET.
1106 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1107 Check toolbar_is_packed.
1108 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1110 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1112 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1113 (xg_update_menubar): Update title only if
1114 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1115 (xg_update_submenu): Skip tearoff only if
1116 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1117 (xg_initialize): Initialize xg_detached_menus only if
1118 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1120 * xterm.h (struct x_output): Surround handlebox_widget with
1121 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1122 toolbar_in_hbox is bool.
1124 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1126 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1127 (LIBS_GNUSTEP): Define.
1128 (LIBES): Add $(LIBS_GNUSTEP).
1129 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1131 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1133 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1134 continuation glyph on a TTY with an indication of an empty line.
1137 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1139 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1140 file's SELinux context or ACLs successfully set, nil otherwise.
1142 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1144 * w32proc.c (reader_thread): Avoid passing NULL handles to
1145 SetEvent and WaitForSingleObject.
1147 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1149 Port EXTERNALLY_VISIBLE to Clang 3.2.
1150 * conf_post.h (__has_attribute): New macro.
1151 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1153 2012-12-27 Glenn Morris <rgm@gnu.org>
1155 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1156 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1158 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1160 * fileio.c (file_name_as_directory, directory_file_name):
1161 Accept an additional argument MULTIBYTE to indicate whether the input C
1162 came from a multibyte or a unibyte Lisp string; all callers
1163 adjusted. Don't assume the input string is always multibyte.
1165 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1166 don't ENCODE_FILE them, and return a unibyte string if the input
1168 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1169 don't assume the input strings will always be multibyte. If the
1170 input strings are multibyte, decode strings obtained from C
1173 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1175 * lisp.h (toplevel): Add two notices to the comment about
1176 defining a new Lisp data type.

1180 * alloc.c (valid_lisp_object_p): Adjust comment.
1182 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1184 * keyboard.c (record_asynch_buffer_change): Initialize an event
1185 only if it's really needed.
1186 * frame.h (enum output_method): Remove output_mac member since
1187 it's a leftover from the deleted code.
1188 * frame.c (Fframep): Adjust user here ...
1189 * terminal.c (Fterminal_live_p): ... and here.
1190 * coding.c (Qmac): Now here because it's only used to denote
1191 end-of-line encoding type.
1192 (syms_of_coding): DEFSYM it.
1193 * frame.h (Qmac): Remove duplicated declaration.
1195 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1197 * window.c (select_window_1): Now static, since it's used only here.
1199 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1201 * window.c (window_body_cols): Subtract display margins from the
1202 window body width on TTYs as well. See
1203 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1204 for the original report.
1206 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1208 * xdisp.c (redisplay_window): Remove inner local variable
1209 because the outer shadowed one has the same meaning.
1210 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1212 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1213 (xg_create_tool_bar): Adjust users.
1215 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1217 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1218 * buffer.c (Fget_buffer_create): Use it to set compact field of
1219 struct buffer_text to avoid accessing an uninitialized value
1220 when compact_buffer is called for the first time.
1221 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1222 (Fset_buffer_modified_p): Use buffer_window_count to check
1223 whether the buffer is displayed in some window.
1224 * xdisp.c (message_dolog): Likewise.
1226 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1228 * w32.c (acl_set_file): If setting the file security descriptor
1229 fails, and the new DACL is identical to the existing one, silently
1230 return success. This fixes problems for users backing up their
1231 own files without having the necessary privileges for setting
1232 security descriptors.
1234 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1236 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1237 after WaitForSingleObject returns normally. This expedites reader
1238 thread shutdown when delete_child triggers it.
1239 (reap_subprocess): More accurate commentary for why we call
1240 delete_child only when cp->fd is negative.
1242 * w32.c (sys_close): Do not call delete_child on a subprocess
1243 whose handle is not yet closed. Instead, set its file descriptor
1244 to a negative value, so that reap_subprocess will call
1245 delete_child on that subprocess when its SIGCHLD arrives.
1246 This avoids closing handles used for communications between sys_select
1247 and reader_thread, which doesn't give sys_select a chance to
1248 notice that the process exited and invoke the SIGCHLD handler for
1251 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1253 * nsfns.m (Fns_do_applescript): Run event loop until script has
1254 been executed (Bug#12969).

1260 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1262 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1264 * w32term.c (w32fullscreen_hook): New function.
1265 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1267 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1269 * fileio.c (Finsert_file_contents): Doc fix.
1271 * w32proc.c (new_child, delete_child, find_child_pid): For a
1272 subprocess, consider its slot being in use as long as its process
1273 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1274 slot when a new process is started immediately after killing
1275 another one, without waiting enough time for the first process to
1276 be reaped and resources allocated for it be orderly freed.
1278 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1280 2012-12-21 Chong Yidong <cyd@gnu.org>
1282 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1284 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1286 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1288 * w32.c (get_name_and_id): Always pass NULL as the first argument
1289 of lookup_account_sid. Avoids crashes with UNC file names that
1290 refer to DFS domains, not to specific machine names. (Bug#12621)
1291 Remove now unused argument FNAME; all callers changed.
1292 (get_file_owner_and_group): Remove now unused argument FNAME; all
1295 2012-12-21 Chong Yidong <cyd@gnu.org>
1297 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1298 error for invalid chars, don't check for a nil return value.
1300 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1302 Avoid calls to CHAR_TO_BYTE if byte position is known.
1303 * editfns.c (make_buffer_string_both): Use move_gap_both.
1304 (Fbuffer_string): Use make_buffer_string_both.
1305 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1307 (buf_bytepos_to_charpos): Likewise.
1308 (charpos_to_bytepos): Remove.
1309 * fileio.c (Finsert_file_contents): Use move_gap_both.
1310 * search.c (Freplace_match): Likewise.
1311 * process.c (process_send_region): Likewise. Use convenient
1312 names for byte positions.
1313 * lisp.h (charpos_to_bytepos): Remove prototype.
1314 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1315 * insdel.c (move_gap): Likewise.

1321 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1323 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1324 (redisplay_internal): Don't bother selecting the frame to get the
1325 proper value of frame-local variables (bug#13225).
1327 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1329 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1330 Rename 4th argument since it may be buffer or string. Adjust comment.
1331 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1333 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1335 * coding.c (Fdetect_coding_region): Do not check start and end with
1336 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1337 (code_convert_region): Likewise.
1339 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1341 * w32.c (acl_get_file, acl_set_file): Run the file name through
1342 map_w32_filename, and resolve any symlinks in the file name, like
1344 (acl_set_file): Call revert_to_self, if any privileges were
1347 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1349 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1350 ($(BLD)/w32.$(O)): Update dependencies.
1352 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1354 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1355 propagate redisplay's scrolling (if any) to the right window.
1356 (redisplay_internal): Use ensure_selected_frame.
1357 (display_mode_lines): Complete last fix.
1358 * window.c (select_window_1): New func, extracted from select_window.
1359 (select_window): Use it.
1360 * window.h (select_window_1): Declare.
1362 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1364 Emulate Posix ACL APIs on MS-Windows.
1365 * w32.c: Include sddl.h and sys/acl.h.

1384 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1386 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1388 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1389 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1390 for some of that bug's symptoms can now cause Emacs to abort.
1391 Remove the workaround.
1392 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1393 The bug that caused SIGCHLD to get lost has been fixed, and the
1394 workaround for it can now cause Emacs to abort.
1396 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1398 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1399 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1400 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1402 2012-12-16 Romain Francoise <romain@orebokech.com>
1404 * fileio.c (Ffile_acl, Fset_file_acl): New functions.

1444 delete the file, record it as pending deletion when the subprocess

1455 Fix permissions bugs with setgid directories etc. (Bug#13125)
1456 * dired.c (Ffile_attributes): Return t as the 9th attribute,

1459 file-ownership-preserved-p instead, with its new group arg.
1460 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1469 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1470 try to get accurate owner and group information from NT file
1471 security APIs. This is to make most callers of 'stat' and
1472 'lstat', which don't need that information, much faster.
1474 * dired.c (Ffile_attributes) [WINDOWSNT]:
1475 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1476 owner and group information from 'lstat'.

1480 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1481 as that confuses set-auto-coding, so insist on the head-read
1482 returning the full 1024 bytes. Let lseek compute the tail offset;
1483 less work for us. Do not ignore I/O errors when reading the tail.

1510 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1512 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1513 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1514 Remove unnecessary S_ISLNK test, as (contra the comments) this
1515 function can't copy symlinks. Improve quality of error message
1516 when attempting to copy files that are neither regular files nor

1548 left_box_line_p and right_box_line_p flags of the glyph for R2L
1549 glyph rows. (Bug#13011)

1596 variable here so various initialization calls DTRT.
1598 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1599 (hinst): Remove unneeded extern declaration.
1600 (_start): Remove initialization of above variables; remove

1820 * frame.c (make_frame): Do not set window's buffer to t.
1821 * window.c (Fsplit_window_internal): Likewise. Previously it was

1824 (Fset_window_buffer): ... is always true and can be removed.
1826 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1828 Convenient macro to check whether the buffer is hidden.

1858 (call_process_kill): Use it.
1859 This does not change call_process_kill's behavior.
1860 * process.c (Fdelete_process): Use record_kill_process to fix a
1861 race condition that could cause Emacs to lose track of a child.

1872 fails, signal an error instead of continuing with an empty
1874 Encode expanded temp file pattern before passing it to mkstemp or
1877 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1878 Encode the file name before passing it to dostounix_filename, in
1879 case it will downcase it (under w32-downcase-file-names).
1882 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1884 Minor call-process cleanups.
1885 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1886 at the same time as other platforms, to simplify analysis.
1887 No need for fd0_volatile since we have synch_process_fd.

1900 * frame.h (struct frame): Remove set-but-not-used space_width member.
1901 (FRAME_SPACE_WIDTH): Remove.
1902 * nsterm.m, w32term.c, xterm.c: Adjust users.
1903 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1904 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1905 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1906 members to a bitfields.
1908 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1910 Don't let call-process be a zombie factory (Bug#12980).
1911 Fixing this bug required some cleanup of the signal-handling code.
1912 As a side effect, this change also fixes a longstanding rare race
1913 condition whereby Emacs could mistakenly kill unrelated processes,
1914 and it fixes a bug where a second C-g does not kill a recalcitrant
1915 synchronous process in GNU/Linux and similar platforms.
1916 The patch should also fix the last vestiges of Bug#9488,
1917 a bug which has mostly been fixed on the trunk by other changes.
1918 * callproc.c, process.h (synch_process_alive, synch_process_death)
1919 (synch_process_termsig, sync_process_retcode):
1920 Remove. All uses removed, to simplify analysis and so that
1921 less consing is done inside critical sections.
1922 * callproc.c (call_process_exited): Remove. All uses replaced
1923 with !synch_process_pid.
1924 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1925 These take the role of what used to be in unwind-protect arg.
1927 (block_child_signal, unblock_child_signal):
1928 New functions, to avoid races that could kill innocent-victim processes.
1929 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1930 (call_process_kill): Record killed processes as deleted, so that
1931 zombies do not clutter up the system. Do this inside a critical
1932 section, to avoid a race that would allow the clutter.
1933 (call_process_cleanup): Fix code so that the second C-g works again
1934 on common platforms such as GNU/Linux.
1935 (Fcall_process): Create the child process in a critical section,
1936 to fix a race condition. If creating an asynchronous process,
1937 record it as deleted so that zombies do not clutter up the system.
1938 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1939 light of these changes. Omit unnecessary call to emacs_close
1940 before failure, as the unwind-protect code does that.
1941 * callproc.c (call_process_cleanup):
1942 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1943 * process.c (record_deleted_pid): New function, containing
1944 code refactored out of Fdelete_process.
1945 (Fdelete_process): Use it.
1946 (process_status_retrieved): Remove. All callers changed to use
1947 child_status_change.
1948 (record_child_status_change): Remove, folding its contents into ...
1949 (handle_child_signal): ... this signal handler. Now, this
1950 function is purely a handler for SIGCHLD, and is not called after
1951 a synchronous waitpid returns; the synchronous code is moved to
1952 wait_for_termination. There is no need to worry about reaping
1953 more than one child now.
1954 * sysdep.c (get_child_status, child_status_changed): New functions.
1955 (wait_for_termination): Now takes int * status and bool
1956 interruptible arguments, too. Do not record child status change;
1957 that's now the caller's responsibility. All callers changed.
1958 Reimplement in terms of get_child_status.
1959 (wait_for_termination_1, interruptible_wait_for_termination):
1960 Remove. All callers changed to use wait_for_termination.
1961 * syswait.h: Include <stdbool.h>, for bool.
1962 (record_child_status_change, interruptible_wait_for_termination):
1964 (record_deleted_pid, child_status_changed): New decls.
1965 (wait_for_termination): Adjust to API changes noted above.
1967 * bytecode.c, lisp.h (Qbytecode): Remove.
1968 No longer needed after 2012-11-20 interactive-p changes.
1970 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1972 * xdisp.c (redisplay_window): If the cursor is visible, but inside

1982 * lisp.h (modify_region): Rename to...
1983 (modify_region_1): ...new prototype.
1984 * textprop.c (modify_region): Now static. Adjust users.
1985 * insdel.c (modify_region): Rename to...
1986 (modify_region_1): ...new function to work with current buffer.
1987 Adjust comment and users. Use true and false for booleans.
1989 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1991 * alloc.c (free_save_value): New function.
1992 (safe_alloca_unwind): Use it.
1993 * lisp.h (free_save_value): New prototype.
1994 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1996 (save_excursion_restore): Adjust to match saved data structure.
1997 Use free_save_value to offload some work from GC. Drop obsolete
2000 2012-12-03 Chong Yidong <cyd@gnu.org>
2002 * fileio.c (Vauto_save_list_file_name): Doc fix.
2004 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2006 * w32fns.c: Remove prototype of atof.
2007 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2009 (file_dialog_callback): Make it UINT_PTR.
2011 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2014 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2015 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2018 2012-12-03 Glenn Morris <rgm@gnu.org>
2020 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2022 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2024 Fix xpalloc confusion after memory is exhausted.
2025 * alloc.c (xpalloc): Comment fix.
2026 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2027 and signals an error, do not clear charset_table_size, as
2028 charset_table is still valid.
2029 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2031 Use execve to avoid need to munge environ (Bug#13054).
2032 * callproc.c (Fcall_process):
2033 * process.c (create_process):
2034 Don't save and restore environ; no longer needed.
2035 * callproc.c (child_setup):
2036 Use execve, not execvp, to preserve environ.
2038 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2040 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2042 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2044 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2045 display for sliced images (Bug#10500).
2047 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2049 2012-11-30 Juanma Barranquero <lekktu@gmail.com>

2052 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2054 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2056 * xdisp.c (window_outdated): Remove eassert since it hits
2057 some suspicious corner cases (see Bug#13007 and Bug#13012).
2058 (mode_line_update_needed): New function.
2059 (redisplay_internal, redisplay_window): Use it.
2060 (ensure_selected_frame): New function.
2061 (redisplay_internal, unwind_redisplay): Use it.
2062 (redisplay_internal): Move comment about buffer_shared...
2063 (buffer_shared_and_changed): ...near to its real use.
2065 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2067 * callproc.c (Fcall_process): Don't misreport vfork failure.
2069 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2071 * callproc.c (Fcall_process): Fix vfork portability problems.
2072 Do not assume that fd[0], count, filefd, and save_environ survive
2073 vfork. Fix bug whereby wrong errno value could be reported for
2074 pipe failure. Some minor cleanups, too, as follows. Move buf and
2075 bufsize to the context where they're needed. Change new_argv to
2076 be of type char **, as this is more convenient and avoids casts.
2077 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2078 Now local constants, not macros.
2080 2012-11-18 Kenichi Handa <handa@gnu.org>
2082 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2083 for the variable "f".
2085 2012-11-13 Kenichi Handa <handa@gnu.org>
2087 * font.c (font_unparse_xlfd): Exclude special characters from the
2088 generating XLFD name.
2090 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2115 violations when repeatedly clicking on the "Top" link of the
2116 "bread-crumbs" in Info buffers.

2130 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2131 between bpos_covered and bpos_max. This fixes cursor display when
2132 several display strings follow each other.
2134 * .gdbinit (pgx): If the glyph's object is a string, display the
2135 pointer to string data, rather than the value of the string object
2136 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2138 * indent.c (Fvertical_motion): If the starting position is covered
2139 by a display string, return to one position before that, to avoid
2140 overshooting it inside move_it_to. (Bug#12930)
2142 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2161 of a literal "/". (Bug#12955)
2162 (gl-stamp): Invoke fc.exe directly, not through cmd.

2167 * dired.c: Assume HAVE_DIRENT_H.
2168 (NAMLEN): Remove, replacing with ...
2169 (dirent_namelen): New function. All uses changed. Use the GNU macro
2170 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2171 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2172 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2173 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2175 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2176 * ndir.h: Rename to ../nt/inc/dirent.h.
2177 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2178 Do not include <dirent.h>; no longer needed.
2179 * w32.c: Include <dirent.h> rather than "ndir.h".
2181 2012-11-23 Chong Yidong <cyd@gnu.org>
2183 * xftfont.c (xftfont_open): Remove duplicate assignment.
2185 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2187 * alloc.c (Fgarbage_collect): Unblock input after clearing
2188 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2189 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2190 * msdos.c (IT_frame_up_to_date): Use it here...
2191 * w32term.c (w32_frame_up_to_date): ...here...
2192 * xterm.c (XTframe_up_to_date): ...and here...

2235 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2237 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2238 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2239 Define for the MSVC compiler.
2241 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

2246 dostounix_filename assumes it gets a unibyte string.
2247 Reported by Michel de Ruiter <michel@sentient.nl>, see

2296 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2298 * w32select.c: Include w32common.h before w32term.h, so that
2299 windows.h gets included before w32term.h uses some of its
2300 features, see below.
2302 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2304 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2315 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2316 Needed following 2012-10-20 change. (Bug#12902)
2318 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2320 * w32proc.c (waitpid): Remove unused label get_result.

2332 * emacs.c, term.c (O_RDWR): Remove.
2333 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than

2337 (create_pty, Fmake_network_process, server_accept_connection)

2340 (wait_reading_process_output): Put in a special case for WINDOWSNT
2341 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2342 It's not clear this is needed, but it's a more-conservative change.
2343 (create_process): Assume FD_CLOEXEC.
2344 (create_process, create_pty): Assume O_NOCTTY.
2345 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2346 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.

2348 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2349 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2351 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2352 lack it, since gnulib guarantees this.
2353 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2355 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2357 * w32.c (faccessat): Pretend that directories have the execute bit
2358 set. Emacs expects that, e.g., in files.el:cd-absolute.
2360 * w32proc.c (create_child): Don't clip the PID of the child
2361 process to fit into an Emacs integer, as this is no longer a
2363 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2364 reaping only the process specified by PID argument, if that is
2365 positive. Use PID instead of dead_child to know which process to
2366 reap. Wait for the child to die only if WNOHANG is not in
2368 (sys_select): Don't set dead_child.
2370 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2371 as it is no longer needed.
2373 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2375 (record_child_status_change): Remove the setting of
2376 record_at_most_one_child for the !WNOHANG case.
2378 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2380 Fix problems in ns port found by static checking.
2381 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2382 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2383 not to process group.
2384 (ns_select): Use emacs_write, not write, as that's more robust
2385 in the presence of signals.
2386 (fd_handler:): Check for read errors.
2388 2012-11-16 Glenn Morris <rgm@gnu.org>
2390 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2392 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2394 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2396 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2398 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2399 use the same value of thread handle.
2400 (start_timer_thread): If the timer thread exited (due to error),
2401 clean up by closing the two handles it used. Duplicate the caller
2402 thread's handle here, so it gets duplicated only once, when
2403 launching the timer thread. Set priority of the timer thread, not
2405 (getitimer): Don't duplicate the caller thread's handle here.
2408 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2410 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2413 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2415 Remove no-longer-used pty_max_bytes variable.
2416 * process.c (pty_max_bytes): Remove; unused.
2417 (send_process): Do not set it.
2419 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2421 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2422 Update dependencies.
2424 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2426 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2427 This follows up on the 2012-09-29 patch that removed indirection
2428 for the 'function' field. Reported by Sergey Vinokurov in
2429 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2431 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2433 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2434 different name, as the MS runtime does not have such a function,
2435 and probably never will.) All callers changed. Ignore DIRFD
2436 value if PATH is an absolute file name, to match Posix spec
2437 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2440 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2442 * xdisp.c (echo_area_display, redisplay_internal):
2443 Omit redundant check whether frame_garbaged is set.
2445 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2447 Use faccessat, not access, when checking file permissions (Bug#12632).
2448 This fixes a bug that has been present in Emacs since its creation.
2449 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2450 which must set some sort of record. (Torek's bug report was against
2451 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2452 same common flaw.) See Torek's Usenet posting
2453 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2454 Posted: Fri Apr 8 14:18:56 1983.
2455 * Makefile.in (LIB_EACCESS): New macro.
2457 * callproc.c (init_callproc):
2458 * charset.c (init_charset):
2459 * fileio.c (check_existing, check_executable, check_writable)
2461 * lread.c (openp, load_path_check):
2462 * process.c (allocate_pty):
2464 Use effective UID when checking permissions, not real UID.
2465 * callproc.c (init_callproc):
2466 * charset.c (init_charset):
2467 * lread.c (load_path_check, init_lread):
2468 Test whether directories are accessible, not merely whether they exist.
2469 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2470 * fileio.c (check_existing, check_executable, check_writable)
2472 Use symbolic names instead of integers for the flags, as they're
2474 (check_writable): New arg AMODE. All uses changed.
2475 Set errno on failure.
2476 (Ffile_readable_p): Use faccessat, not stat + open + close.
2477 (Ffile_writable_p): No need to call check_existing + check_writable.
2478 Just call check_writable and then look at errno. This saves a syscall.
2479 dir should never be nil; replace an unnecessary runtime check
2480 with an eassert. When checking the parent directory of a nonexistent
2481 file, check that the directory is searchable as well as writable, as
2482 we can't create files in unsearchable directories.
2483 (file_directory_p): New function, which uses 'stat' on most platforms
2484 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2485 (Ffile_directory_p, Fset_file_times): Use it.
2486 (file_accessible_directory_p): New function, which uses a single
2487 syscall for efficiency.
2488 (Ffile_accessible_directory_p): Use it.
2489 * xrdb.c (file_p): Use file_directory_p.
2490 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2491 * lread.c (openp): When opening a file, use fstat rather than
2492 stat, as that avoids a permissions race. When not opening a file,
2493 use file_directory_p rather than stat.
2494 (dir_warning): First arg is now a usage string, not a format.
2495 Use errno. All uses changed.
2496 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2497 that merely introduced a race.
2498 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2499 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2500 and similarly for the other O_* flags.
2501 * w32.c (sys_faccessat): Rename from sys_access and switch to
2502 faccessat's API. All uses changed.
2503 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2504 (magic_db): Rename from magic_file_p.
2505 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2506 char *, so that we don't have to test for file existence
2507 separately from opening the file for reading. This removes a race
2508 fixes a permission-checking problem, and simplifies the code.
2510 (file_p): Remove; no longer needed.
2512 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2514 Omit glyphs initialization at startup.
2515 * dispnew.c (glyphs_initialized_initially_p): Remove.
2516 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2517 (Fredraw_frame): Move actual code from here...
2518 (redraw_frame): ...to here. Add eassert. Adjust comment.
2519 (Fredraw_display): Use redraw_frame.
2520 * xdisp.c (clear_garbaged_frames): Likewise.
2522 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2524 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2525 passed to pint2str and pint2hrstr to be at most the size of the
2526 frame's decode_mode_spec_buffer. This avoids crashes with very
2527 large values of FIELD_WIDTH argument to decode_mode_spec.
2530 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2532 Fix a race with verify-visited-file-modtime (Bug#12863).
2533 Since at least 1991 Emacs has ignored an mtime difference of no
2534 more than one second, but my guess is that this was to work around
2535 file system bugs that were fixed long ago. Since the race is
2536 causing problems now, let's remove that code.
2537 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2538 whose time stamp is off by no more than a second. Insist that the
2539 file time stamps match exactly.
2541 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2543 * frame.h (struct frame): Convert external_tool_bar member to
2544 1-bit unsigned bitfield.
2545 * termhooks.h (struct terminal): Remove mouse_moved member since
2546 all users are long dead. Adjust comment on mouse_position_hook.
2548 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2550 Simplify by using FOR_EACH_FRAME here and there.
2551 * frame.c (next_frame, prev_frame, other_visible_frames)
2552 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2553 * w32term.c (x_window_to_scroll_bar): Likewise.
2554 * window.c (window_list): Likewise.
2555 * xdisp.c (x_consider_frame_title): Likewise.
2556 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2557 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2558 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2559 * xmenu.c (menubar_id_to_frame): Likewise.
2560 * xselect.c (frame_for_x_selection): Likewise.
2561 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2562 (x_window_to_menu_bar): Likewise.
2563 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2565 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2567 * data.c (Qdefalias_fset_function): Now static.
2569 Another tweak to vectorlike_header change.
2570 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2571 Remove, and replace all uses with ...
2572 (next_in_free_list, set_next_in_free_list):
2573 New functions, which respect C's aliasing rules better.
2575 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2577 * window.c (list4i): Rename from 'quad'. All uses changed.
2578 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2580 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2582 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2583 warning about mixing declarations and code in ISO C90.
2585 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2587 * window.c (Fsplit_window_internal): Set combination limit of
2588 new parent window to t iff Vwindow_combination_limit is t;
2589 fixing a regression introduced with the change from 2012-09-22.
2590 (Fset_window_combination_limit): Fix doc-string.
2592 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2594 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2595 amount when the scroll margins are too large. When scrolling
2596 backwards in the buffer, give up if cannot reach point or the
2597 scroll margin within a reasonable number of screen lines.
2598 Fixes point position in window under scroll-up/down-aggressively when
2599 point is positioned many lines beyond the window top/bottom.
2602 * ralloc.c (relinquish): If real_morecore fails to return memory
2603 to the system, don't crash; instead, leave the last heap
2604 unchanged and return. (Bug#12774)
2606 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2608 * lisp.h (AUTOLOADP): New macro.
2609 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2610 * data.c (Ffset): Remove special ad-advice-info handling.
2611 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2613 (Finteractive_form): Simplify.
2614 (Fquo): Don't insist on having at least 2 arguments.
2615 (Qdefalias_fset_function): New var.
2617 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2619 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2621 * nsfont.m (Qcondensed, Qexpanded): New variables.
2622 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2623 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2625 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2627 Fix recently introduced crash on MS-Windows (Bug#12839).
2628 * w32term.h (struct scroll_bar): Use convenient header.
2629 (SCROLL_BAR_VEC_SIZE): Remove.
2630 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2632 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2634 Tweak last vectorlike_header change.
2635 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2636 vectorlike object on the free list. This is introduced to avoid
2637 some (but not all) pointer casting and aliasing problems, see
2638 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2639 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2641 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2643 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2645 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2646 been removed, so remove them here also.
2648 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2650 * doc.c (Fdocumentation): Handle new property
2651 dynamic-docstring-function to replace the old ad-advice-info.
2653 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2655 * fns.c (Qeql, hashtest_eq): Now static.
2657 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2659 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2660 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2661 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2662 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2664 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2666 Use same hash function for hashfn_profiler as for hash_string etc.
2667 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2668 * lisp.h (sxhash_combine): New inline function, with the contents
2669 of the old SXHASH_COMBINE.
2670 * profiler.c (hashfn_profiler): Use it, instead of having a
2671 special hash function containing a comparison that always yields 1.
2673 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2675 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2676 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2677 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2680 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2682 * image.c (xpm_make_color_table_h): Fix compiler error because
2683 make_hash_table changed.
2685 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2687 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2689 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2691 Use ad-hoc comparison function for the profiler's hash-tables.
2692 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2693 (make_log): Use them.
2694 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2695 call Fequal any more.
2696 (Ffunction_equal): New function.
2697 (cmpfn_profiler, hashfn_profiler): New functions.
2698 (syms_of_profiler): Initialize them.
2699 * lisp.h (struct hash_table_test): New struct.

2704 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2705 (hash_lookup, hash_remove_from_table): Move assertion checking of
2706 hashfn result here. Check hash-equality before calling cmpfn.
2707 (Fmake_hash_table): Adjust call to make_hash_table.
2708 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2709 (syms_of_fns): Initialize them.
2710 * emacs.c (main): Move syms_of_fns earlier.
2711 * xterm.c (syms_of_xterm):
2712 * category.c (hash_get_category_set): Adjust call to make_hash_table.
2713 * print.c (print_object): Adjust to new hash-table struct.
2714 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2716 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2718 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2719 value of w32-scroll-lock-modifier is neither nil nor one of the
2720 known key modifiers. (Bug#12806)
2722 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2724 Shrink struct vectorlike_header to the only size field.
2725 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2727 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2728 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2729 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2730 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2731 information from the vector header. Adjust comment.
2732 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2733 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2735 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
2736 (struct vectorlike_header): Remove next member. Adjust comment.
2737 (struct Lisp_Subr): Add convenient header. Adjust comment.
2738 (allocate_pseudovector): Adjust prototype.
2739 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
2740 (sweep_string, lisp_malloc): Remove useless prototypes.
2741 (enum mem_type): Adjust comment.
2742 (NEXT_IN_FREE_LIST): New macro.
2743 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2744 (Fmake_bool_vector): Likewise.
2745 (struct large_vector): New type to represent allocation unit for
2746 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2747 (large_vectors): Change type to struct large_vector.
2748 (allocate_vector_from_block): Simplify.
2749 (PSEUDOVECTOR_NBYTES): Replace with...
2750 (vector_nbytes): ...new function. Adjust users.
2751 (sweep_vectors): Adjust processing of large vectors.
2752 (allocate_vectorlike): Likewise.
2753 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2754 Add easserts. Adjust XSETPVECTYPESIZE usage.
2755 (allocate_buffer): Use BUFFER_PVEC_INIT.
2756 (live_vector_p): Adjust to match large vector.
2757 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2758 * buffer.h (struct buffer): Add next member.
2759 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2761 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2762 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2763 (copy_hash_table): Adjust to match vector header change.
2764 * lread.c (defsubr): Use XSETPVECTYPE.
2765 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2766 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2767 (xvecsize): New command.
2769 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2771 * keyboard.c (event_to_kboard): Do not dereference
2772 frame_or_window field of SELECTION_REQUEST_EVENT
2773 and SELECTION_CLEAR_EVENT events (Bug#12814).
2774 * xterm.h (struct selection_input_event): Adjust comment.
2776 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2778 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2779 such as Scroll Lock, if the respective keys are treated as
2780 function keys, not as modifiers. This avoids destroying non-ASCII
2781 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2783 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2785 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2787 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2789 Restore some duplicate definitions (Bug#12814).
2790 This undoes part of the 2012-11-03 changes. Some people build
2791 with plain -g rather than with -g3, and they need the duplicate
2792 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2793 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2794 Define as macros, as well as as enums or as constants.
2796 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2798 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2799 to keypad keys (Bug#12816).
2801 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2803 Minor adjustments of recently-changed frame functions.
2804 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2805 known to be a frame (we're in the FRAMEP branch).
2806 * lisp.h (Qframep): Remove decl. frame.h declares this.
2807 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2808 since they're meant for Lisp fixnum values.
2810 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2812 * window.c (Fwindow_combination_limit): Revert to the only
2813 required argument and adjust docstring as suggested in
2814 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2815 by Martin Rudalics <rudalics@gmx.at>.
2817 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2819 Widely used frame validity and checking functions.
2820 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2821 * frame.c (decode_live_frame, decode_any_frame): New functions.
2822 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2823 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2824 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2825 (Fframe_pointer_visible_p): Use decode_any_frame.
2826 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2827 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2828 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2829 (Fframe_focus): Likewise. Allow zero number of arguments.
2831 (frame_buffer_list, frame_buffer_predicate): Remove.
2832 * lisp.h (frame_buffer_predicate): Remove prototype.
2833 * buffer.c (Fother_buffer): Use decode_any_frame.
2834 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2835 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2836 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2837 (Fclose_font, Ffont_info): Use decode_live_frame.
2838 * fontset.c (check_fontset_name): Likewise.
2839 * terminal.c (Fframe_terminal): Likewise.
2840 * w32fns.c (check_x_frame): Likewise.
2841 * window.c (Fminibuffer_window, Fwindow_at)
2842 (Fcurrent_window_configuration): Likewise.
2843 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2844 Likewise. Allow zero number of arguments. Adjust docstring.
2845 * dispnew.c (Fredraw_frame): Likewise.
2846 * xfaces.c (frame_or_selected_frame): Remove.
2847 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2848 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2849 (Fframe_face_alist): Use decode_live_frame.
2850 * xfns.c (check_x_frame): Likewise.
2852 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2854 * window.c (quad): New function.
2855 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2856 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2857 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2858 (Fwindow_line_height): Use it.
2859 (Fwindow_fringes): Use list3.
2860 (Fwindow_scroll_bars): Use list4.
2861 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2862 (Fwindow_combination_limit): Allow zero number of arguments.
2864 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2866 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2868 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2869 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2870 file descriptor 2 for standard error. (Bug#12805)
2872 2012-11-05 Chong Yidong <cyd@gnu.org>
2874 * process.c (wait_reading_process_output): Revert previous change.
2876 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2878 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2879 This removes code that has been obsolete since around 1990.
2880 * callproc.c (Fcall_process):
2882 * process.c (create_process):
2883 * term.c (dissociate_if_controlling_tty):
2884 Assume setsid exists.
2885 * callproc.c (child_setup): Assume setpgid exists and behaves as
2886 per POSIX.1-1988 or later.
2887 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2888 * emacs.c (shut_down_emacs):
2889 * sysdep.c (sys_suspend, init_foreground_group):
2890 Assume getpgrp behaves as per POSIX.1-1998 or later.
2891 * msdos.c (setpgrp): Remove.
2892 (tcgetpgrp, setpgid, setsid): New functions.
2893 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2894 * term.c (no_controlling_tty): Remove; unused.
2895 * w32proc.c (setpgrp): Remove.
2896 (setsid, tcgetpgrp): New functions.
2898 Simplify by assuming __fpending.
2899 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2900 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2901 Do not assume that __fpending's result fits in int.
2903 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2905 Remove EMACS_OUTQSIZE+sleep hack.
2906 * dispnew.c (update_frame_1): Remove hack for terminals slower
2907 than 2400 bps, which throttled Emacs by having it sleep.
2908 This code hasn't worked since at least 2007, when the multi-tty stuff
2909 was added, and anyway those old terminals are long dead.
2910 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2911 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2913 Fix data-loss with --version (Bug#9574).
2914 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2915 as we can't assume that emacs_strerror is initialized, and strerror
2916 is good enough here.
2917 (main): Invoke atexit earlier, to catch earlier instances of
2918 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2920 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2922 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2923 (keyDown): Remap keypad keys to X11 virtual key codes.
2925 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2927 Fix data-loss with --batch (Bug#9574).
2928 * emacs.c: Include <close-stream.h>.
2929 (close_output_streams): New function.
2930 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2931 and handles errors appropriately.
2932 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2935 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2936 The symptom is a diagnostic "GLib-WARNING **: In call to
2937 g_spawn_sync(), exit status of a child process was requested but
2938 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2939 waitpid(), so exit status can't be returned." The diagnostic
2940 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2941 The real bug is a race condition between Emacs and glib: Emacs
2942 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2943 so that glib can't find it. Work around the bug by invoking
2944 waitpid only on subprocesses that Emacs itself creates.
2945 * process.c (create_process, record_child_status_change):
2946 Don't use special value -1 in pid field, as the caller now must
2947 know the pid rather than having the callee infer it.
2948 The inference was sometimes incorrect anyway, due to another race.
2949 (create_process): Set new 'alive' member if child is created.
2950 (process_status_retrieved): New function.
2951 (record_child_status_change): Use it.
2952 Accept negative 1st argument, which means to wait for the
2953 processes that Emacs already knows about. Move special-case code
2954 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2955 processes that have already been waited for, by testing and
2956 clearing new 'alive' member.
2957 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2958 now does this internally.
2959 (handle_child_signal): Let record_child_status_change do all
2960 the work, since we do not want to reap all exited child processes,
2961 only the child processes that Emacs itself created.
2962 * process.h (Lisp_Process): New boolean member 'alive'.
2964 Omit duplicate definitions no longer needed with gcc -g3.
2965 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2966 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2967 Define only as macros. There's no longer any need to also define
2968 these symbols as enums or as constants, since we now assume
2969 gcc -g3 when debugging.
2971 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2973 * lisp.mk: Adjust comments to the fact that term/internal is now
2974 loaded from loadup.el.
2976 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2977 (msdos_fatal_signal): New function.
2978 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2981 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2982 for GCC versions before 4.
2983 (emacs_raise): Define to call msdos_fatal_signal.
2985 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2986 iterator when starting in the middle of a display or overlay
2989 2012-11-03 Chong Yidong <cyd@gnu.org>
2991 * process.c (wait_reading_process_output): Clean up the last
2994 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2996 * process.c (wait_reading_process_output): Avoid a race condition
2997 with SIGIO delivery (Bug#11536).
2999 2012-11-03 Chong Yidong <cyd@gnu.org>
3001 * buffer.c (cursor_type): Untabify docstring.
3003 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3005 * frame.h (struct frame): Drop can_have_scroll_bars member
3006 which is meaningless for a long time. Adjust comments.
3007 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3008 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3010 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3012 * window.c (decode_next_window_args): Update window arg after
3013 calling decode_live_window and so fix crash reported at
3014 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3015 by Juanma Barranquero <lekktu@gmail.com>.
3016 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3017 * font.c (Ffont_at): Likewise.
3019 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3021 * widget.c (resize_cb): New function.
3022 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3023 (EmacsFrameResize): Check if all is up to date before changing frame
3026 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3028 Implement backtrace output for fatal errors on MS-Windows.
3029 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3030 (BACKTRACE_LIMIT_MAX): New macro.
3031 (w32_backtrace): New function.
3032 (emacs_abort): Use w32_backtrace when the user chooses not to
3033 attach a debugger. Update the text of the abort dialog.
3035 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3037 Window-related stuff cleanup here and there.
3038 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3039 Use decode_any_window.
3040 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3041 * xdisp.c (Fformat_mode_line): Likewise.
3042 * font.c (Ffont_at): Use decode_live_window.
3043 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3044 * window.c (decode_next_window_args): Likewise.
3045 (decode_any_window): Remove static.
3046 * window.h (decode_any_window): Add prototype.
3047 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3048 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3051 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3053 Remove pad from struct input_event.
3054 * termhooks.h (struct input_event): Remove padding field.
3056 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3057 member is never cons for a long time. Adjust comment.
3058 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3059 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3060 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3061 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3063 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3065 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3067 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3069 Fix crash when using Emacs as commit editor for git (Bug#12697).
3070 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3071 and it is configured in conf_post.h.
3072 (Fcall_process): Don't invoke both setsid and setpgid; the former
3073 is enough, if it exists.
3074 * callproc.c (Fcall_process, child_setup):
3075 * process.c (create_process): Use setpgid.
3076 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3078 * dispnew.c (init_display): Initialize the foreground group
3079 if we are running a tty display.
3080 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3081 * lisp.h (init_foreground_group): New decl.
3082 * sysdep.c (inherited_pgroup): New static var.
3083 (init_foreground_group, tcsetpgrp_without_stopping)
3084 (narrow_foreground_group, widen_foreground_group): New functions.
3085 (init_sys_modes): Narrow foreground group.
3086 (reset_sys_modes): Widen foreground group.
3088 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3090 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3092 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3094 * minibuf.c (read_minibuf): Restore current buffer since
3095 choose_minibuf_frame calling Fset_frame_selected_window may
3096 change it (Bug#12766).
3098 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3100 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3102 2012-10-30 Kenichi Handa <handa@gnu.org>
3104 * font.c (Ffont_at): If WINDOW is specified and it is not
3105 displaying the current buffer, signal an error.
3107 2012-10-29 Daniel Colascione <dancol@dancol.org>
3109 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3110 In preparation for fixing bug#12739, move these functions from
3113 * coding.h, coding.c: ... to here, and compile them only when
3114 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3115 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3117 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3119 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3120 (timer_loop, getitimer, setitimer): Use it instead of
3121 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3123 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3126 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3128 * nsterm.m (NO_APPDEFINED_DATA): New define.
3129 (last_appdefined_event_data): New variable
3130 (last_appdefined_event): Remove.
3131 (ns_select): Initialize t from last_appdefined_event_data instead
3132 of [last_appdefined_event data1].
3133 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3134 remove last_appdefined_event (Bug#12698).
3136 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3138 * frame.c (x_set_font): Catch internal error.
3140 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3142 Avoid overflow in w32 implementation of interval timers.
3143 When possible, for ITIMER_PROF count only times the main thread
3145 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3146 'volatile ULONGLONG' types. All the other data which was
3147 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3148 (GetThreadTimes_Proc): New typedef.
3149 (w32_get_timer_time): New function, returns a suitable time value
3151 (timer_loop): Enter critical section when accessing ULONGLONG
3152 values of the itimer_data struct, as these accesses are no longer
3153 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3154 Remove unused variable.
3155 (init_timers): Initialize s_pfn_Get_Thread_Times.
3156 (start_timer_thread): Don't assign itimer->caller_thread here.
3157 (getitimer): Assign itimer->caller_thread here.
3158 (setitimer): Always call getitimer to get the value of ticks_now.
3159 (sys_spawnve): Avoid compiler warning about format mismatch.
3161 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3163 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3164 mouse movement events if the menu bar is active. This avoids
3165 producing a busy "hour-glass" cursor by Windows if the mouse
3166 pointer is positioned over a tooltip shown for some menu item.
3168 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3170 Don't assume process IDs fit in int.
3171 * emacs.c (shut_down_emacs) [!DOS_NT]:
3172 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3173 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3174 Use pid_t, not int, to store process IDs, as 'int'
3175 is not wide enough on a few platforms (e.g., AIX and IRIX).
3177 2012-10-23 Kenichi Handa <handa@gnu.org>
3179 The following change is to make face-font-rescale-alist work
3180 correctly for non-ASCII fonts.
3182 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3183 (font_open_for_lface): Handle Vface_font_rescale_alist.
3185 2012-10-23 Chong Yidong <cyd@gnu.org>
3187 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3189 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3191 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3193 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3195 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3198 2012-10-21 Glenn Morris <rgm@gnu.org>
3200 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3202 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3204 Port to OpenBSD 5.1.
3205 * frame.c (Fmouse_position, Fmouse_pixel_position):
3206 * xdisp.c (produce_stretch_glyph):
3207 Declare local vars only when they're needed.
3208 This is clearer and avoids a warning on OpenBSD about unused vars.
3209 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3210 This is safer, and avoids OpenBSD warnings about unused vars.
3211 * keyboard.c (record_menu_key): Remove unnecessary decl.
3212 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3213 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3214 as our definition clashes with OpenBSD's.
3215 * xfaces.c (load_face_colors, check_lface_attrs)
3216 (get_lface_attributes_no_remap, get_lface_attributes)
3217 (lface_fully_specified_p, x_supports_face_attributes_p)
3218 (tty_supports_face_attributes_p, face_fontset, realize_face)
3219 (realize_x_face, realize_tty_face):
3220 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3221 merely Lisp_Object *. This is more informative and avoids
3222 a warning on OpenBSD about accessing beyond an object's size.
3224 2012-10-20 Chong Yidong <cyd@gnu.org>
3226 * lread.c (Fload): Doc fix (Bug#12592).
3228 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3230 * font.c (Ffont_at): Fix previous change.
3232 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3234 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3235 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3238 * alloc.c (NSTATICS): Decrease to 0x800.

3720 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3721 needs fork-then-exec for daemon launching.
3723 * font.h: Include frame.h.
3725 * image.c: Use the image library cache machinery only when we're
3726 compiling for native WINDOWSNT; Cygwin can use shared libraries
3727 like any other Unixlike system.
3729 * keyboard.c: Clarify a comment regarding the input loop.
3731 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3732 functions directly instead of trying to detect at runtime that our
3733 host operating system supports them. We make this change for two
3734 reasons: Cygwin lacks support for the multibyte character
3735 conversion functions used by the legacy menu code, and Cygwin
3736 never needs to rely on non-Unicode APIs.
3738 * unexw32.c (hinst): Declare extern.
3740 * w32.c: Change header order;
3741 (w32_strerror): Move to w32fns.c because we need it for
3742 non-WINDOWSNT builds.
3744 * w32.h: Add #error macro to make sure we don't include w32.h for
3745 Cygwin builds. Remove w32select declarations.
3747 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3748 w32fns.c. w32console.c is WINDOWSNT-only.
3750 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3751 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3753 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3754 (w32_major_version, w32_minor_version, w32_build_number)
3755 (os_subtype, sound_type): Define here
3756 (w32_defined_color): Make color parameter const for consistency
3757 with other _defined_color functions.
3758 (w32_createwindow): Unconditionally call w32_init_class instead of
3759 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3760 through the code is complex and unnecessary because class
3761 registration is practically free.
3762 (w32_name_of_message): New EMACSDEBUG-only function.
3763 (Fset_message_beep): Move here
3764 (Fx_open_connection): Require that the display name for Windows be
3765 "w32" for consistency, emacsclient disambiguation, and maybe, one
3766 day, multi-window-system support.
3767 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3768 Cygwin files for W32 GUI facilities, since these clearly don't
3769 expect Cygwin names.
3770 (_DebPrint): Define.
3771 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3772 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3773 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3774 (w32_last_error): Remove.
3776 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3778 * w32heap.c (syspage_mask): Declare here.
3779 (cache_system_info): Remove.
3781 * w32inevt.c (faked_key): Define globally, not statically.
3782 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3783 (w32_console_toggle_lock_key): Move to w32fns.c.
3785 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3787 * w32proc.c (_DebPrint): Move to w32fns.c.
3788 * w32select.c: Include string.h, stdio.h for Cygwin.
3789 * w32select.h: New File.
3791 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3793 (w32_message_fd): New variable. Under Cygwin, holds the file
3794 descriptor the system used to tell us about pending thread
3797 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3798 that prevented compilation under non-WINDOWSNT systems.
3800 (w32_initialize): Open /dev/windows and assign it to
3801 w32_message_fd. Provide w32 feature.
3803 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3804 (WM_EMACS_INPUT_READY): add.
3805 (prepend_msg, w32_message_fd): Declare globally.
3808 (keyboard_handle): Use only when WINDOWSNT.
3809 (notify_msg_ready): New function. Posts a message to the main
3810 thread's message queue under CYGWIN, which wakes up the main
3811 thread from select(2) by making the /dev/windows file descriptor
3812 ready. Under WINDOWSNT, it sets an event the same way the old
3815 (post, prepend_msg): Actually call notify_msg_ready instead of
3816 setting the input event directly.
3818 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3820 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3821 but it still has blocs in it, don't return it to the system,
3822 instead of aborting. (Bug#12402)
3824 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3826 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3828 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3829 MAC_OS_X_VERSION_10_6.
3830 (syms_of_nsterm): Remove comment about Panther and above for
3832 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3833 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3834 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3836 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3837 MAC_OS_X_VERSION_10_4.
3839 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3840 MAC_OS_X_VERSION_10_2.
3842 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3844 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3845 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3847 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3848 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3849 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3850 Remove ns_in_resize check.
3851 (ns_clear_frame_area): Remove resize handle code.
3853 * nsfns.m (ns_in_resize): Remove.
3854 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3855 Remove ns_in_resize check.
3857 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3859 Improve sys_siglist detection.
3860 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3861 defined as a macro, as is done in Solaris.
3862 (sys_siglist_entries): New macro.
3863 (save_strsignal): Use it.
3864 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3865 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3867 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3869 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3870 fullscreen/Fullscreen.
3872 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3873 tobar_height is new.
3875 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3876 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3877 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3878 (windowDidResize:): Check for correct window if old style fullscreen.
3879 Capitalize word in comment. Remove incorrect comment.
3880 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3881 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3882 error in drawing background.
3883 (toggleFullScreen:): Remove comment. Rearrange calls.
3884 Set toolbar values to zero, save old height in tobar_height.
3885 Restore tool bar height when leaving fullscreen.
3886 (canBecomeMainWindow): New function.
3888 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3890 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3892 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3894 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3896 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3897 that time stamps of directories could also be changed.
3898 Don't request the too broad GENERIC_WRITE, only the more restrictive
3899 FILE_WRITE_ATTRIBUTES access rights.
3901 * fileio.c (Fset_file_times): Special-case ignoring errors for
3902 directories only on MSDOS, not on MS-Windows.
3904 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3906 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3908 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3910 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3911 see whether CreateFile failed.
3913 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3915 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3916 to avoid similar races.
3917 * keyboard.c (pending_signals): Now bool, not int.
3919 Port timers to OpenBSD, plus check for timer failures.
3920 OpenBSD problem reported by Han Boetes.
3921 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3923 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3924 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3925 like OpenBSD, which has timer_settime but does not declare it.
3926 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3927 whether to use itimerspec-related primitives. All uses of
3928 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3930 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3932 * profiler.c (handle_profiler_signal): Fix a malloc race
3933 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3935 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3937 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3939 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3941 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3942 consistent with the change in return value of 'safe_strsignal'.
3944 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3946 Prefer plain 'static' to 'static inline' (Bug#12541).
3947 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3948 (bidi_set_sor_type, bidi_push_embedding_level)
3949 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3950 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3954 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3955 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3956 Now 'static', not 'static inline'.
3958 Count overruns when profiling; change units to ns.
3959 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3960 Give extra weight to samples after overruns, to attempt to count
3961 the time more accurately.
3962 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3963 the underlying primitives nominally do ns.
3964 (Fprofiler_cpu_start): Document the change. Mention that
3965 the sampling intervals are only approximate.
3967 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3969 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3971 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3972 case for the special 0 coding-system.
3974 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3975 (Fmake_overlay): Remove redundant tests.
3976 (fix_start_end_in_overlays): Remove redundant recentering.
3978 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3980 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3981 Update dependencies.
3983 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3985 Fix a malloc race condition involving strsignal.
3986 A signal can arrive in the middle of a malloc, and Emacs's signal
3987 handler can invoke strsignal, which can invoke malloc, which is
3988 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3989 Fix it by altering the signal handler so that it does not invoke
3991 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3992 * process.c (status_message): Use const pointer, in case strsignal
3993 is #defined to safe_strsignal.
3994 * sysdep.c (sys_siglist, init_signals): Always define and
3995 initialize a substitute sys_siglist if the system does not define
3996 one, even if HAVE_STRSIGNAL.
3997 (safe_strsignal): Rename from strsignal. Always define,
3998 using sys_siglist. Return a const pointer.
3999 * syssignal.h (safe_strsignal): New decl.
4000 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4002 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4004 * w32proc.c (timer_loop): Fix code that waits for timer
4005 expiration, to avoid high CPU usage.
4007 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4009 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4010 (sweep_weak_table): Remove redundant prototypes.
4012 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4014 * emacs.c: Move the inclusion of TERM_HEADER after including
4015 windows.h on WINDOWSNT. This avoids compilation problems with
4018 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4020 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4021 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4022 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4023 as the previous version used 'void *'.
4025 * ralloc.c (ROUNDUP): Fix last change.
4026 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4029 * w32proc.c <disable_itimers>: New static flag.
4030 (init_timers): Initialize it to zero, after creating the critical
4031 sections used by the timer threads.
4032 (term_timers): Set to 1 before deleting the critical sections.
4033 (getitimer, setitimer): If disable_itimers is non-zero, return an
4034 error indication without doing anything. Reported by Fabrice
4035 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4036 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4038 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4041 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4042 term_ntproc after all the other bookkeeping, to get timers working
4043 as long as possible.
4045 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4047 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4048 Suggested by Juri Linkov in
4049 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4051 Prefer plain 'static' to 'static inline' (Bug#12541).
4052 With static functions, modern compilers inline pretty well by
4053 themselves; advice from programmers often hurts as much as it helps.
4054 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4055 this change shrinks the text size of the Emacs executable by 1.1%
4056 without affecting CPU significantly in my benchmark.
4057 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4058 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4132 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
4133 Now 'static', not 'static inline'.
4136 (bidi_copy_it): Do the whole copy with a single memcpy.
4137 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4139 Revert the FOLLOW-SYMLINKS change for file-attributes.
4140 Doing it right would require several changes to Tramp, and there's
4141 not enough time to get that tested before the freeze today.
4142 * dired.c (directory_files_internal, Ffile_attributes):
4145 * frame.c (x_report_frame_params): Port better to wider ints.
4146 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4147 or that pointers can be printed in 15 decimal digits.
4148 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
4150 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>
4152 Support x64 build on MS-Windows.
4153 * w32term.h (SCROLL_BAR_PACK, SCROLL_BAR_UNPACK): Define for x64.

4155 compatibility with x64.
4156 (x_get_focus_frame): Add prototype.

4340 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4341 signal.h, setjmp.h. Include systime.h instead.

4350 (handle_profiler_signal): Rename from sigprof_handler_1,
4351 for consistency with other handlers. Do not check whether
4352 cpu_log is a hash-table if garbage collecting, since it

4355 for consistency with other handlers.
4356 (setup_cpu_timer): New function, with much of what used to be in

4358 Prefer timer_settime if available, and prefer
4359 thread cputime clocks, then process cputime clocks, then
4360 monotonic clocks, to the old realtime clock. Use make_timeval
4361 to round more-correctly when falling back to setitimer.
4362 (Fprofiler_cpu_start): Use it.
4363 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4616 * makefile.w32-in (BLOCKINPUT_H): Remove.
4617 (SYSSIGNAL_H): New macro.

4633 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4635 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4636 fatal_error_backtrace.
4638 * w32proc.c (sys_kill): Undo last change: don't do anything when
4639 invoked to deliver SIGABRT to our own process. This is now
4640 handled by emacs_raise.
4642 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4644 * w32term.c (w32_read_socket): Remove leftover reference to
4645 interrupt_input_pending.
4647 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4649 Do not use SA_NODEFER.
4650 Problem reported by Dani Moncayo in
4651 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4653 * sysdep.c (emacs_abort): Do not reset signal handler.
4654 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4655 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4656 wanted even on POSIXish hosts, and it doesn't work on Windows.
4658 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4660 * xterm.c (x_term_init): Call fixup_locale before and after calling
4661 gtk_init (Bug#12392).
4663 2012-09-23 Chong Yidong <cyd@gnu.org>
4665 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4666 Vdynamic_library_alist.
4668 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4669 (Fgnutls_available_p): Caller changed.
4671 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4672 (Flibxml_parse_xml_region): Likewise.
4674 * dispextern.h (struct image_type): Remove arg from init function.
4676 * image.c (Finit_image_library, lookup_image_type)
4677 (define_image_type): Remove now-unneeded second arg.
4678 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4679 (init_tiff_functions, init_gif_functions, init_svg_functions):
4680 Arglist and w32_delayed_load calling convention changed.
4681 (gs_type): Remove init_gs_functions; there is no such function.
4682 (valid_image_p, make_image): Fix caller to lookup_image_type.
4684 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4686 Simplify and avoid signal-handling races (Bug#12471).
4688 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4689 Avoid recursive loop if there's a fatal error in the function itself.
4690 * atimer.c (pending_atimers):
4691 * blockinput.h: Don't include "atimer.h"; no longer needed.
4692 (interrupt_input_pending): Remove. All uses removed.
4693 pending_signals now counts both atimers and ordinary interrupts.
4694 This is less racy than having three separate pending-signal flags.
4695 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4697 Rename from their upper-case counterparts BLOCK_INPUT,
4698 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4699 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4700 This makes it easier to access volatile variables more accurately.
4701 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4702 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4703 that's more reliable if the code is buggy and sets
4704 interrupt_input_blocked to a negative value. All uses changed.
4705 * atimer.c (deliver_alarm_signal):
4706 Remove. No need to deliver this to the parent; any thread can
4707 handle this signal now. All uses replaced by underlying handler.
4708 * atimer.c (turn_on_atimers):
4709 * dispnew.c (handle_window_change_signal):
4710 * emacs.c (handle_danger_signal):
4711 * keyboard.c (kbd_buffer_get_event):
4712 Don't reestablish signal handler; not needed with sigaction.
4713 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4715 Rework to avoid unnecessary accesses to volatile variables.
4716 (UNBLOCK_INPUT_TO): Now a function.
4717 (totally_unblock_input, unblock_input): New decls.
4718 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4719 (init_data): Remove. Necessary stuff now done in init_signal.
4720 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4721 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4722 (fatal_error_code): Remove; no longer needed.
4723 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4724 it doesn't always backtrace. All uses changed. No need to reset
4725 signal to default, since sigaction and/or die does that for us now.
4726 Use emacs_raise (FOO), not kill (getpid (), FOO).
4727 (main): Check more-accurately whether we're dumping.
4728 Move fatal-error setup to sysdep.c
4729 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4730 * gtkutil.c (xg_get_file_name, xg_get_font):
4731 Remove no-longer-needed signal-mask manipulation.
4732 * keyboard.c, process.c (POLL_FOR_INPUT):
4733 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4734 * keyboard.c (read_avail_input): Remove.
4735 All uses replaced by gobble_input.
4736 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4737 (kbd_buffer_store_event_hold, gobble_input):
4738 (record_asynch_buffer_change) [USABLE_SIGIO]:
4739 (store_user_signal_events):
4740 No need to mess with signal mask.
4741 (gobble_input): If blocking input and there are terminals, simply
4742 set pending_signals to 1 and return. All hooks changed to not
4743 worry about whether input is blocked.
4744 (process_pending_signals): Clear pending_signals before processing
4745 them, in case a signal comes in while we're processing.
4746 By convention callers now test pending_signals before calling us.
4747 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4748 New functions, to support changes to blockinput.h.
4749 (handle_input_available_signal): Now extern.
4750 (reinvoke_input_signal): Remove. All uses replaced by
4752 (quit_count): Now volatile, since a signal handler uses it.
4753 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4754 All callers changed. Block SIGINT only if not already blocked.
4755 Clear sigmask reliably, even if Fsignal returns, which it can.
4756 Omit unnecessary accesses to volatile var.
4757 (quit_throw_to_read_char): No need to restore sigmask.
4758 * keyboard.c (gobble_input, handle_user_signal):
4759 * process.c (wait_reading_process_output):
4760 Call signal-handling code rather than killing ourselves.
4761 * lisp.h: Include <float.h>, for...
4762 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4763 (pending_signals): Now volatile.
4764 (syms_of_data): Now const if IEEE floating point.
4765 (handle_input_available_signal) [USABLE_SIGIO]:
4766 (terminate_due_to_signal, record_child_status_change): New decls.
4767 * process.c (create_process): Avoid disaster if memory is exhausted
4768 while we're processing a vfork, by tightening the critical section
4770 (send_process_frame, process_sent_to, handle_pipe_signal)
4771 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4773 (send_process): No need for setjmp/longjmp any more, since the
4774 SIGPIPE stuff is now gone. Instead, report an error if errno
4776 (record_child_status_change): Now extern. PID and W are now args.
4777 Return void, not bool. All callers changed.
4778 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4779 Remove. All uses removed. This bug should be fixed now in a
4781 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4782 and record the child status change directly. This avoids the
4783 need to futz with the signal mask.
4784 (process_fatal_action): Move here from emacs.c.
4785 (emacs_sigaction_flags): New function, containing
4786 much of what used to be in emacs_sigaction_init.
4787 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4788 caught by emacs, to make races less likely.
4789 (deliver_process_signal): Rename from handle_on_main_thread.
4791 (BACKTRACE_LIMIT_MAX): Now at top level.
4792 (thread_backtrace_buffer, threadback_backtrace_pointers):
4794 (deliver_thread_signal, deliver_fatal_thread_signal):
4795 New functions, for more-accurate delivery of thread-specific signals.
4796 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4797 (deliver_arith_signal): Handle in this thread, not
4798 in the main thread, since it's triggered by this thread.
4799 (maybe_fatal_sig): New function.
4800 (init_signals): New arg DUMPING so that we can be more accurate
4801 about whether we're dumping. Caller changed.
4802 Treat thread-specific signals differently from process-general signals.
4803 Block all signals while handling fatal error; that's safer.
4804 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4806 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4807 Ignore SIGPIPE unless batch.
4808 (emacs_backtrace): Output backtrace for the appropriate thread,
4809 which is not necessarily the main thread.
4810 * syssignal.h: Include <stdbool.h>.
4811 (emacs_raise): New macro.
4812 * xterm.c (x_connection_signal): Remove; no longer needed
4813 now that we use sigaction.
4814 (x_connection_closed): No need to mess with sigmask now.
4815 (x_initialize): No need to reset SIGPIPE handler here, since
4816 init_signals does this for us now.
4818 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4820 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4821 background rect may be larger (Bug#12245).
4823 2012-09-23 Chong Yidong <cyd@gnu.org>
4825 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4827 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4829 * .gdbinit: Just stop at fatal_error_backtrace.
4830 See Stefan Monnier's request in
4831 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4832 Remove no-longer-used query of system type.
4834 2012-09-22 Chong Yidong <cyd@gnu.org>
4836 * search.c (Freplace_match): Doc fix (Bug#12325).
4838 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4840 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4841 (Fline_end_position): Doc fix.
4843 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4845 2012-09-22 Chong Yidong <cyd@gnu.org>
4847 * dispextern.h (struct image_type): Add new slot, storing a type
4848 initialization function.
4850 * image.c (define_image_type): Call the image initializer function
4851 if it is defined. Arguments and return value changed.
4852 (valid_image_p, make_image): Callers changed.
4853 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4854 (gif_type, imagemagick_type, svg_type, gs_type):
4855 Add initialization functions.
4856 (Finit_image_library): Call lookup_image_type.
4857 (CHECK_LIB_AVAILABLE): Macro deleted.
4858 (lookup_image_type): Call define_image_type here, rather than via
4859 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4860 (syms_of_image): Move define_image_type calls for xbm_type and
4861 pbm_type to lookup_image_type.
4863 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4865 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4866 'idle_timers' from here ...
4867 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4868 lists, to avoid infloops when the timer does something stupid,
4869 like reinvoke itself with the same or smaller time-out.
4872 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4874 * window.c (Fsplit_window_internal): Handle only Qt value of
4875 Vwindow_combination_limit separately.
4876 (Qtemp_buffer_resize): New symbol.
4877 (Vwindow_combination_limit): New default value.
4880 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4882 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4883 the new overlay string. (Bug#10159)
4885 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4887 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4888 or that fprintf is async-signal-safe. POSIX doesn't require
4891 2012-09-22 Chong Yidong <cyd@gnu.org>
4893 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4896 2012-09-22 Kenichi Handa <handa@gnu.org>
4898 * composite.c (composition_reseat_it): Handle the case that a
4899 grapheme cluster is not covered by a single font (Bug#12352).
4901 2012-09-21 Chong Yidong <cyd@gnu.org>
4903 * image.c (define_image_type): Avoid adding duplicate types to
4904 image_types (Bug#12463). Suggested by Jörg Walter.
4906 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4908 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4909 (print_load_command_name): Add case LC_DATA_IN_CODE.
4910 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4912 2012-09-21 Glenn Morris <rgm@gnu.org>
4914 * eval.c (Frun_hook_with_args_until_success)
4915 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4917 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4919 * fileio.c (Ffile_selinux_context): Only call freecon when
4920 lgetfilecon succeeded.
4921 (Fset_file_selinux_context): Likewise. (Bug#12444)
4923 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4925 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4926 reordering, locate the cursor by calling set_cursor_from_row; if
4927 that fails, clear the desired glyph matrix before returning a
4928 failure indication to the caller. Fixes leaving garbled display
4929 when fast scrolling with a down-key. (Bug#12403)
4930 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4931 scrolling through multibyte text.
4933 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4935 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4936 calling mark_vectorlike since that's the one that marks the window.
4937 (mark_discard_killed_buffers): Mark the final cdr.
4938 * window.h (struct window): Move prev/next_buffers to the
4939 non-standard fields.
4940 * window.c (make_window): Initialize prev/next_buffers manually.
4942 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4944 Omit unused arg EXPECTED from socket hooks.
4945 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4946 * nsterm.m (ns_term_init):
4947 * termhooks.h (struct terminal.read_socket_hook):
4948 * w32inevt.c (w32_console_read_socket):
4949 * w32term.c (w32_read_socket):
4950 * xterm.c (XTread_socket):
4951 Omit unused arg EXPECTED. All callers changed.
4952 (store_user_signal_events): Return void, not int, since callers no
4953 longer care about the return value. All uses changed.
4955 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4957 * w32gui.h (XParseGeometry): Do not declare.
4959 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4961 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4962 Ignore 'expected'. See Eli Zaretskii in
4963 <http://bugs.gnu.org/12471#8> (last line).
4965 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4966 (XParseGeometry): Now static. Substitute extremal values for
4967 values that are out of range.
4969 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4971 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4973 * nsfns.m (XParseGeometry): Remove.
4974 (Fx_create_frame): Call x_set_offset to correctly interpret
4975 top_pos in geometry.
4977 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4978 (Fx_parse_geometry): If there is a space in string, call
4979 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4981 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4983 * search.c (scan_buffer): Use character positions in calls to
4984 region_cache_forward and region_cache_backward, not byte
4985 positions. (Bug#12196)
4987 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4988 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4990 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4991 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4992 emacs_blocked_malloc, now deleted.
4994 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4996 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4997 The workaround was for improving performance on Solaris 2.4, but
4998 is getting in the way now. Emacs will still work if someone is
4999 still running Solaris 2.4 in a museum somewhere; Sun dropped
5000 support for Solaris 2.4 in 2003.
5001 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5002 * process.c (create_process) [HAVE_WORKING_VFORK]:
5003 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5004 since Emacs no longer uses vfork on that platform.
5006 2012-09-17 Glenn Morris <rgm@gnu.org>
5008 * emacs.c: Use COPYRIGHT.
5010 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5012 Remove configure's --without-sync-input option (Bug#12450).
5013 When auditing signal-handling in preparation for cleaning it up,
5014 I found that SYNC_INPUT has race conditions and would be a real
5015 pain to fix. Since it's an undocumented and deprecated
5016 configure-time option, now seems like a good time to remove it.
5017 Also see <http://bugs.gnu.org/11080#16>.
5018 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5019 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5020 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5021 (malloc_hysteresis):
5022 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5023 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5024 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5025 (dont_register_blocks, bytes_used_when_reconsidered)
5026 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5027 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5028 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5029 Remove. All uses removed.
5030 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5031 implementation, one that depends on whether the new macro
5032 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5034 * atimer.c (run_timers, handle_alarm_signal):
5035 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5036 (handle_async_input, process_pending_signals)
5037 (handle_input_available_signal, init_keyboard):

5043 * xterm.c (XTread_socket):
5045 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5046 * eval.c (handling_signal): Remove. All uses removed.
5047 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5048 All uses replaced with the SYNC_INPUT version.
5049 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5051 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5054 * font.c (Ffont_shape_gstring): Remove unused local.
5056 2012-09-16 Glenn Morris <rgm@gnu.org>
5058 * Makefile.in (clean): No longer run nextstep's clean.
5060 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5062 (ns-app): Move here from ns.mk, and simplify.
5063 (clean): Simplify nextstep entry.
5064 * ns.mk: Remove file.
5066 2012-09-17 Kenichi Handa <handa@gnu.org>
5068 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5069 not covert the last few charactes.
5071 2012-09-16 Kenichi Handa <handa@gnu.org>
5073 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5074 here, but just check the validity of glyphs in the glyph-string.
5076 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5078 * window.c (Fwindow_parameter, Fset_window_parameter):
5079 Accept any window as argument (Bug#12452).
5081 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5083 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5084 to ns_term_init to avoid memory leak.
5086 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5087 explicit retain/release.
5088 (ns_term_init): Only allow one display. Initialize outerpool and
5091 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5093 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5094 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5095 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5096 the Microsoft problem in a different way, by altering ../nt/config.nt.
5098 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5113 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5114 by lisp.h. This completes removal of setjmp.h inclusion
5115 erroneously announced in the previous commit. (Bug#12446)
5117 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5120 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5121 not defined as a macro. The latter happens on MS-Windows.
5124 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5126 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5127 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5128 Some instances of '#include <setjmp.h>' removed, if the
5129 only reason for the instance was because "lisp.h" was included.
5130 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5131 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5132 and _longjmp with the new symbols. Emacs already uses _setjmp if
5133 available, so this change affects only POSIXish hosts that have
5134 sigsetjmp but not _setjmp, such as some versions of Solaris and
5135 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5136 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5137 (png_load_body) [HAVE_PNG]:
5138 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5139 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5140 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5141 since PNG requires jmp_buf. This is the only exception to the
5142 general rule that we now use sys_setjmp and sys_longjmp.
5143 This exception is OK since this code does not change the signal
5144 mask or longjmp out of a signal handler.
5146 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5148 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5149 Include "syssignal.h", for 'main_thread'.
5151 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5153 Avoid out-of-range marker position (Bug#12426).
5154 * insdel.c (replace_range, replace_range_2):
5155 Adjust markers before overlays, as suggested by comments.
5156 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5157 Remove redundant check before calling offset_intervals.
5159 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5161 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5162 current buffer (Bug#12387).
5164 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5166 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5168 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5170 Use a more backwards-compatible timer format (Bug#12430).
5171 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5172 vector element, not from the 4th, since PSECS is now at the end.
5173 (Fcurrent_idle_time): Doc fix.
5175 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5177 Function to mark objects and remove killed buffers at once.
5178 * alloc.c (discard_killed_buffers): Rename to ...
5179 (mark_discard_killed buffers) ... new name. Add marking
5180 of remaining objects. Fix comment. Adjust users.
5181 (mark_object): Do not touch frame buffer lists here.
5182 * frame.c (delete_frame): Reset frame buffer lists here.
5184 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5186 Better workaround for GNOME bug when --enable-gcc-warnings.
5187 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5188 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5189 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5191 Simplify SIGIO usage (Bug#12408).
5192 The code that dealt with SIGIO was crufty and confusing, e.g., it
5193 played tricks like "#undef SIGIO" but these tricks were not used
5194 consistently. Simplify mostly by not #undeffing standard symbols,
5195 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5196 or not as we please) rather than "defined SIGIO" (standard symbol
5197 that we probably shouldn't #undef).
5198 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5199 Modules that need it can include it.
5200 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5201 * dispextern.h (ignore_sigio): New decl.
5202 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5203 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5204 * emacs.c (shut_down_emacs):
5205 * keyboard.c (kbd_buffer_store_event_hold):
5206 Use ignore_sigio rather than invoking 'signal' directly.
5207 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5209 (FIONREAD, SIGIO): Do not #undef.
5210 (tty_read_avail_input): Use #error rather than a syntax error.
5211 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5212 for I_PIPE, used by SETUP_SLAVE_PTY.
5213 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5214 * sysdep.c (croak): Remove; no longer needed. This bit of
5215 temporary code, with Fred N. Fish's comment that it's temporary,
5216 has been in Emacs since at least 1992!
5217 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5218 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5219 * syssignal.h (croak): Remove decl.
5220 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5221 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5222 now that we're termios-only.
5223 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5224 * term.c (dissociate_if_controlling_tty): Use #error rather than
5227 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5228 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5229 to work around GNOME bug 683906.
5230 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5231 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5232 This works around GCC bug 54561.
5234 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5236 More fixes for 'volatile' and setjmp/longjmp.
5237 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5238 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5239 (png_load_body) [HAVE_PNG]:
5240 (jpeg_load_body) [HAVE_JPEG]:
5241 New function, with most of the old parent function's body.
5242 (png_load) [HAVE_PNG]:
5243 (jpeg_load) [HAVE_JPEG]:
5244 Invoke the new function, to avoid longjmp munging our locals.
5245 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5246 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5247 longjmp is passed 2, as the C standard doesn't guarantee this.
5248 Instead, store the failure code into mgr->failure_code.
5250 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5252 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5253 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5254 (syms_of_keyboard): Remove support for unread-command-char.
5256 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5258 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5259 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5260 violation. (Bug#12426)
5262 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5264 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5266 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5268 * eval.c: Add `inhibit-debugger'.
5269 (Qinhibit_debugger): New symbol.
5270 (call_debugger): Bind it instead of Qdebug_on_error.
5271 (maybe_call_debugger): Test Vinhibit_debugger.
5272 (syms_of_eval): Define inhibit-debugger.
5273 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5274 (syms_of_xdisp): Remove inhibit-debug-on-message.
5276 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5278 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5279 If a nonvolatile local variable is written before a _longjmp to
5280 the frame containing the variable, and is read after the _longjmp,
5281 the value read is indeterminate. Some local variables of type
5282 'struct handler' and 'struct catchtag' are used in this way, so
5283 mark each of their slots as volatile if the slot can be set before
5284 _longjmp and read afterwards.
5285 * lisp.h (struct handler): var and chosen_clause are now volatile.
5286 (struct catchtag): val, next, and pdlcount are now volatile.
5288 * bidi.c (bidi_push_it, bidi_pop_it):
5289 * fns.c (copy_hash_table):
5290 * image.c (define_image_type):
5291 * keyboard.c (kbd_buffer_store_event_hold):
5292 * process.c (Fprocess_send_eof):
5293 * xfaces.c (x_create_gc) [HAVE_NS]:
5294 * xgselect.c (xg_select):
5295 Prefer assignment to memcpy when either will do.
5297 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5298 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5299 time an item is removed. No need to mark this function 'inline';
5300 the compiler knows better than we do.
5302 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5304 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5305 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5306 to change_frame_size (Bug#12388).
5307 (windowDidResize:): Pass YES to updateFrameSize.
5309 * nsterm.h: Add delay parameter to updateFrameSize.
5311 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5313 Discard killed buffers from deleted window and frame objects.
5314 This reduces an amount of references to killed buffers and
5315 helps GC to reclaim them faster.
5316 * alloc.c (discard_killed_buffers): New function.
5317 (mark_object): Use it for deleted windows and frames.
5318 (mark_object): If symbol's value is set up for a killed buffer
5319 or deleted frame, restore its global binding.
5320 * data.c (swap_in_global_binding): Add GC notice.
5321 (swap_in_symval_forwarding): Use convenient set_blv_where.
5322 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5323 * window.h: ... to here.
5325 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5327 Convenient macro to check whether the buffer is live.
5328 * buffer.h (BUFFER_LIVE_P): New macro.
5329 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5330 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5332 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5334 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5335 composition cases (Bug#12364).
5337 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5338 overhang of succeeding glyphs overlapping box cursor.
5340 * w32term.c (x_draw_glyph_string): Likewise.
5342 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5344 Simplify, document, and port floating-point (Bug#12381).
5345 The porting part of this patch fixes bugs on non-IEEE platforms
5346 with frexp, ldexp, logb.
5347 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5349 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5350 support, by removing commented-out code and briefly listing the
5351 C89 functions excluded. The commented-out stuff was confusing
5352 maintenance, e.g., we thought we needed cbrt but it was commented out.
5353 (logb): Remove decl; no longer needed.
5354 (isfinite): New macro, if not already supplied.
5355 (isnan): Don't replace any existing macro.
5356 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5357 are present on all C89 platforms.
5358 (Ffrexp): Do not special-case zero, as frexp does the right thing
5360 (Flogb): Do not use logb, as it doesn't have the desired meaning
5361 on hosts that use non-base-2 floating point. Instead, stick with
5362 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5363 frexp, to avoid getting an unspecified result.
5365 * xdisp.c (Qinhibit_debug_on_message): Now static.
5367 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5369 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5370 NSBezierPath (Bug#12131).
5372 2012-09-10 Chong Yidong <cyd@gnu.org>
5374 * fns.c (Fdelq, Fdelete): Doc fix.
5376 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5378 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5379 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5381 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5383 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5384 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5387 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5389 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5390 left fringe if the window has a left margin. This avoids leaving
5391 traces of the cursor because its leftmost pixel is not drawn over.
5393 * dispnew.c (update_window_line): When the left margin area of a
5394 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5395 that screen line. (Bug#12277)
5397 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5399 Assume C89 or later for math functions (Bug#12381).
5400 This simplifies the code, and makes it a bit smaller and faster,
5401 and (most important) makes it easier to clean up signal handling
5402 since we can stop worring about floating-point exceptions in
5403 library code. That was a problem before C89, but the problem
5404 went away many years ago on all practical Emacs targets.
5405 * data.c, image.c, lread.c, print.c:
5406 Don't include <math.h>; no longer needed.
5407 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5408 might be autoconfigured, as that never happens.
5410 * doprnt.c (DBL_MAX_10_EXP):
5411 * print.c (DBL_DIG):
5412 Remove. C89 or later always defines these.
5413 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5414 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5415 (arith_error, domain_error, domain_error2):
5416 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5417 no longer needed -- we simply return what C returns. All uses removed.
5418 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5420 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5421 Remove. All uses expanded, as these macros are no longer used
5422 more than once and are now more trouble than they're worth.
5423 (Ftan): Use tan, not sin / cos.
5424 (Flogb): Assume C89 frexp.
5425 (fmod_float): Assume C89 fmod.
5426 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5427 (init_floatfns): Remove. All uses removed.
5429 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5431 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5432 compositeToPoint for OSX < 10.6 (Bug#12390).
5434 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5436 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5437 This produces more-accurate results.
5439 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5441 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5442 changes (Bug#12088).
5444 2012-09-08 Chong Yidong <cyd@gnu.org>
5446 * syntax.c (Fstring_to_syntax): Doc fix.
5448 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5450 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5451 in the internal border.
5452 (x_set_window_size): Remove static variables and their usage.
5453 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5454 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5455 Remove fringe/internal border adjustment (Bug#11052).
5456 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5457 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5458 (ns_fix_rect_ibw): Remove.
5459 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5460 (ns_dumpglyphs_box_or_relief): Ditto.
5461 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5463 (ns_dumpglyphs_image): Ditto.
5464 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5466 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5467 their usage. Add fringe_extended_p and its use as in other terms.
5468 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5469 scroll bar was removed.
5470 (updateFrameSize): New function.
5471 (windowDidResize): Move code to updateFrameSize and call it.
5473 * nsterm.h (EmacsView): Add updateFrameSize.
5475 2012-09-07 Chong Yidong <cyd@gnu.org>
5477 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5479 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5481 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5483 More signal-handler cleanup (Bug#12327).
5484 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5485 Problem introduced when merging patches. Noted by Eli Zaretskii in
5486 <http://bugs.gnu.org/12327#67>.
5487 * floatfns.c: Comment fix.
5488 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5489 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5490 and anyway the declaration is harmless even if SIGDANGER is not defined.
5491 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5492 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5493 source files not surprisingly expected syssignal.h to define, or
5494 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5495 Include <sys/ioctl.h>, for FIONREAD.
5496 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5497 This eliminates a problem whereby other files mysteriously had
5498 to include "syssignal.h" before including "systty.h" if they
5499 wanted to use "#ifdef SIGIO".
5501 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5503 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5505 * w32.c (sigemptyset): Empty the set.
5506 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5508 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5510 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5512 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5513 (mark_object): Likewise for frame objects.
5515 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5517 * syssignal.h (handle_on_main_thread): Always declare,
5518 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5519 This ports to platforms without HAVE_PTHREAD.
5521 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5523 Signal-handler cleanup (Bug#12327).
5524 Emacs's signal handlers were written in the old 4.2BSD style with
5525 sigblock and sigmask and so forth, and this led to some
5526 inefficiencies and confusion. Rewrite these to use
5527 pthread_sigmask etc. without copying signal sets around. Also,
5528 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5529 'signal', and instead use functions that do not attempt to take
5530 over the system name space. This patch causes Emacs's text
5531 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5532 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5533 Do not include <signal.h> or "syssignal.h", as these
5534 modules do not use signals.
5535 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5536 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5537 Do not include <signal.h>, as "syssignal.h" does that for us now.
5538 * atimer.c (sigmask_atimers): New function.
5539 (block_atimers, unblock_atimers): New functions,
5540 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5542 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5543 no longer needed here.
5544 * emacs.c (main): Inspect existing signal handler with sigaction,
5545 so that there's no need to block and unblock SIGHUP.
5546 * sysdep.c (struct save_signal): New member 'action', replacing
5547 old member 'handler'.
5548 (save_signal_handlers, restore_signal_handlers):
5549 Use sigaction instead of 'signal' to save and restore.
5550 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5551 New function. All users of 'signal' modified to use set_sighandler
5552 if they're writeonly, and to use sys_signal if they're read+write.
5553 (emacs_sigaction_init, forwarded_signal): New functions.
5554 (sys_signal): Remove. All uses replaced by calls to sigaction
5555 and emacs_sigaction_init, or by direct calls to 'signal'.
5556 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5557 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5558 all uses replaced by pthread_sigmask etc. calls.
5559 * syssignal.h: Include <signal.h>.
5560 (emacs_sigaction_init, forwarded_signal): New decls.
5561 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5562 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5563 (sigmask, sys_sigmask): Remove; no longer needed.
5564 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5565 (sigblock, sigunblock, sigfree):
5566 (sigsetmask) [!defined sigsetmask]:
5567 Remove. All uses replaced by pthread_sigmask.
5568 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5569 no longer need to be replaced, and its typical old uses
5570 are now done via emacs_sigaction_init and sigaction.
5571 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5572 (sys_sigdel): Remove; unused.
5573 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5575 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5577 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5578 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5580 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5582 Explicitly mark buffer_defaults and buffer_local_symbols.
5583 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5584 mark_local_symbols here.
5585 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5586 since special buffers aren't marked here any more.
5587 (allocate_buffer): Chain new buffer with all_buffers here...
5588 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5590 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5591 (syms_of_buffer): Remove staticpro of the above.
5592 (init_buffer_once): Set names for buffer_defaults and
5593 buffer_local_symbols.
5595 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5597 Use bool for booleans in font-related modules.
5598 * font.c (font_intern_prop, font_style_to_value)
5599 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5600 (generate_otf_features, font_check_otf_features, font_check_otf)
5601 (font_match_p, font_list_entities, font_at):
5602 * fontset.c (fontset_id_valid_p, reorder_font_vector
5603 (fontset_find_font, Fset_fontset_font)
5604 (face_suitable_for_char_p) [0]:
5605 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5606 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5607 (m17n_flt_initialized, ftfont_shape_by_flt):
5608 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5609 * nsfont.m (nsfont_draw):
5610 * w32font.c (w32font_draw):
5611 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5612 Use bool for booleans.
5613 * font.h: Adjust to above API changes.
5614 (struct font, struct font_driver, struct font_driver_list):
5615 Use bool for booleans.
5616 (struct font): Remove useless member encoding_type.
5618 * fontset.c, xftfont.c: Omit unnecessary static decls.
5620 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5622 * alloc.c (mark_object): Revert window marking code
5623 since it's unsafe for the Fset_window_configuration.
5625 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5627 Fix race conditions with signal handlers and errno (Bug#12327).
5628 Be more systematic about preserving errno whenever a signal
5629 handler returns, even if it's not in the main thread. Do this by
5630 renaming signal handlers to distinguish between signal delivery
5631 and signal handling. All uses changed.
5632 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5633 * data.c (deliver_arith_signal): Rename from arith_error.
5634 * dispnew.c (deliver_window_change_signal): Rename from
5635 window_change_signal.
5636 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5637 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5638 * keyboard.c (deliver_input_available_signal): Rename from
5639 input_available_signal.
5640 (deliver_user_signal): Rename from handle_user_signal.
5641 (deliver_interrupt_signal): Rename from interrupt_signal.
5642 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5643 (deliver_child_signal): Rename from sigchld_handler.
5644 * atimer.c (handle_alarm_signal):
5645 * data.c (handle_arith_signal):
5646 * dispnew.c (handle_window_change_signal):
5647 * emacs.c (handle_fatal_signal, handle_danger_signal):
5648 * keyboard.c (handle_input_available_signal):
5649 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5650 * process.c (handle_pipe_signal, handle_child_signal):
5651 New functions, with the actual signal-handling code taken from the
5652 original respective signal handlers, sans the sporadic attempts to
5653 preserve errno, since that's now done by handle_on_main_thread.
5654 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5655 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5656 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5658 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5659 Move initialization of main_thread to sysdep.c's init_signals.
5660 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5661 our usage, and simplifies the mainline code.
5662 (record_child_status_change): New static function, as a helper
5663 for handle_child_signal, and with most of the old child handler's
5665 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5666 (handle_child_signal): Use the above.
5667 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5668 Moved here from emacs.c.
5669 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5670 code moved here from emacs.c's main function.
5671 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5672 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5673 This lets callers save and restore errno properly.
5675 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5677 Remove redundant or unused things here and there.
5678 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5679 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5680 * editfns.c (Fcompare_buffer_substrings): Likewise.
5681 * frame.h (struct terminal, struct font_driver_list):
5682 Remove redundant declarations.
5683 * window.h (Qleft, Qright): Likewise.
5685 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5687 Do not mark objects from deleted buffers, windows and frames.
5688 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5689 (mark_object): Likewise for windows and frames.
5691 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5693 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5694 buffer_defaults and buffer_local_symbols as valid objects.
5695 Return special value to denote them.
5697 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5699 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5700 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5701 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5702 (file_name_absolute_p, Fsubstitute_in_file_name):
5703 (check_executable, check_writable, Ffile_accessible_directory_p)
5704 (Fset_file_selinux_context, Fdefault_file_modes)
5705 (Finsert_file_contents, choose_write_coding_system)
5706 (Fwrite_region, build_annotations, a_write, e_write)
5708 * filelock.c (boot_time_initialized, get_boot_time)
5709 (get_boot_time_1, lock_file_1, within_one_second):
5710 * floatfns.c (in_float):
5711 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5712 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5713 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5714 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5715 * window.c (compare_window_configurations):
5716 Use bool for booleans.
5717 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5718 (Fdefault_file_modes): Now mode_t, not int, for modes.
5719 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5720 (internal_delete_file): Now returns void, not a (boolean) int,
5721 since nobody was looking at the return value.
5722 * lisp.h, window.h: Adjust to above API changes.
5724 * xdisp.c (set_message): Simplify and reindent last change.
5726 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5728 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5730 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5732 * eval.c (call_debugger): Make the function non-static so that we
5733 can call it from set_message.
5735 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5736 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5738 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5740 Give more-useful info on a fatal error (Bug#12328).
5741 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5742 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5743 of doing the work ourselves.
5744 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5745 do most of the work.
5746 (fatal_error_backtrace): New function, taken from the guts
5747 of the old fatal_error_signal, but with a new option to output
5749 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5750 info about the signal than just its number.
5751 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5752 * sysdep.c: Include <execinfo.h>
5753 (emacs_backtrace): New function, taken partly from the previous
5754 code of the 'die' function.
5755 (emacs_abort): Call fatal_error_backtrace rather than abort.
5757 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5759 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5760 eager (load-time) macro-expansion.
5761 * lisp.mk (lisp): Add macroexp.
5763 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5765 Simplify redefinition of 'abort' (Bug#12316).
5766 Do not try to redefine the 'abort' function. Instead, redo
5767 the code so that it calls 'emacs_abort' rather than 'abort'.
5768 This removes the need for the NO_ABORT configure-time macro
5769 and makes it easier to change the abort code to do a backtrace.
5770 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5771 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5772 Remove; sysdep.c's emacs_abort now takes its place.
5773 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5774 'abort' changed to use 'emacs_abort'.
5775 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5776 (abort) [!defined abort]: Rename to ...
5777 (emacs_abort): ... new name.
5778 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5779 the place of the old 'abort' in emacs.c.
5780 * w32.c, w32fns.c (abort): Do not #undef.
5781 * w32.c (emacs_abort): Rename from w32_abort.
5783 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5785 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5786 offsets[j].dv, since the y axis of the screen coordinates points
5787 down, while the y axis of the font definition coordinates points
5788 up. This fixes display of Arabic diacritics such as KASRA and
5789 KASRATAN. (Bug#11860)
5791 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5793 Be more systematic about _setjmp vs setjmp.
5794 * alloc.c (test_setjmp, mark_stack):
5795 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5796 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5797 (png_load, my_error_exit, jpeg_load):
5798 * process.c (send_process_trap, send_process):
5799 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5800 The underscored versions are up to 30x faster on some hosts.
5801 Formerly, the code used setjmp+longjmp sometimes and
5802 _setjmp+_longjmp at other times, with no particular reason to
5803 prefer setjmp+longjmp.
5805 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5807 Fix minor problem found by static checking.
5808 * buffer.c (Fdelete_all_overlays): Return nil.
5810 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5812 * buffer.c (Fdelete_all_overlays): New function.
5814 2012-09-03 Chong Yidong <cyd@gnu.org>
5816 * gtkutil.c: Add extern decl for Qxft.
5818 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5820 * emacs.c, eval.c: Use bool for boolean.
5821 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5822 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5823 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

5829 * process.c (read_process_output, exec_sentinel):
5830 Use bool for booleans.
5831 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5832 All callers changed.
5833 * eval.c (interactive_p): Omit always-true boolean argument
5834 EXCLUDE_SUBRS_P. All callers changed.
5835 * dispextern.h, lisp.h: Reflect above API changes.
5836 * firstfile.c (dummy): Use the address of 'main', whose signature
5837 won't change, instead of the address of 'initialize', whose
5838 signature just changed from int to bool.
5839 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5840 * msdos.c (fatal_error_in_progress): ... from here.
5841 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5843 (redisplay_internal, unwind_redisplay): Simply clear
5844 REDISPLAYING_P when unwinding, instead of saving its previous,
5845 always-false value and then restoring it.
5847 Clean up some extern decls.
5848 Mostly, this hoists extern decls out of .c files and into .h files.
5849 That way, we're more likely to catch errors if the interfaces change.
5850 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5851 declare xg_mark_data.
5852 * dispextern.h (x_frame_parm_handlers):
5854 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5855 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5856 (Qultra_bold, Qoblique, Qitalic):
5857 Move extern decl here from .c file.
5858 * alloc.c (xg_mark_data) [USE_GTK]:
5860 * eval.c (Qlexical_binding):
5861 * fns.c (time) [!HAVE_UNISTD_H]:

5870 * xfont.c (x_clear_errors):
5871 * xterm.c (x_frame_parm_handlers):
5872 Remove now-redundant extern decls.
5873 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5874 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5876 * xfaces.c: Remove unnecessary static decls.
5877 * xterm.c (updating_frame): Remove decl of nonexistent object.
5879 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5880 when building globals.h, as the objects that are not built on
5881 this host are not needed to compile C files on this host.
5883 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5885 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5887 * frame.h: Add missing prototype for x_wm_set_size_hint.
5889 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5894 (Fsubstitute_command_keys):

5899 (make_buffer_string, make_buffer_string_both)
5900 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5918 2012-09-02 Chong Yidong <cyd@gnu.org>
5920 * keymap.c (push_key_description): Print M-TAB as C-M-i

5935 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5936 more than one grapheme cluster passed to the shaper: compute the
5937 offset adjustment values separately for each cluster. (Bug#11860)
5939 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5940 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5941 about implicit conversions from integer to pointer.
5943 2012-09-01 Daniel Colascione <dancol@dancol.org>
5945 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

5963 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5964 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
5965 all of which have been moved to common code.
5967 * xfaces.c: Include TERM_HEADER instead of listing all possible
5968 window-system headers.
5970 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

5999 window system declarations.
6001 * frame.h: Move common functions here: set_frame_menubar,
6002 x_set_window_size, x_sync, x_get_focus_frame,
6003 x_set_mouse_position, x_set_mouse_pixel_position,
6004 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
6005 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
6006 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,

6034 the frames which are reachable from Vframe_list.
6035 * term.c (mark_ttys): Remove.
6036 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6038 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

6060 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6061 for GCC 4.7.1 x86-64.
6063 2012-08-30 Glenn Morris <rgm@gnu.org>
6065 * lread.c (init_lread): For out-of-tree builds, only add the
6066 source directory's site-lisp dir to the load-path if it exists,
6067 consistent with in-tree builds. (Bug#12302)
6069 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6071 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6088 Handle click on close button as quit.
6090 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6091 Add window_closed and button_values. Add void as return value for
6092 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6093 Add process_dialog as new member.
6095 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6097 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6098 is not one of the heaps we manage. (Bug#12242)
6100 2012-08-28 Glenn Morris <rgm@gnu.org>
6102 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

6303 It was meant to be temporary and it often doesn't work,
6304 because when IDX has side effects the behavior of IDX==IDX
6305 is undefined. See Stefan Monnier in
6306 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6308 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6317 as that's faster and simpler than static storage. Don't bother
6318 with the g_main_context_query overhead if g_main_context_pending
6319 says no events are pending.
6320 (gfds, gfds_size): Remove these static vars.
6321 (xgselect_initialize): Remove; no longer needed.
6322 All uses and decls removed.
6324 * emacs.c (fatal_error_signal_hook): Remove.

6352 Use bool for booleans, instead of int.
6353 * lisp.h, process.h: Adjust prototypes to match above changes.
6354 * callint.c (Fcall_interactively): Don't assume the mark's
6355 offset fits in 'int'.

6367 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6368 Use bool for booleans, instead of int.
6369 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6370 since the 1-or-0 return value is always ignored anyway.
6371 (mmap_initialized_p):
6372 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6373 * buffer.h, lisp.h: Adjust prototypes to match above changes.

6377 * bidi.c: Use bool for boolean.
6378 This is a bit more readable, and makes the text segment of bidi.o
6379 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6380 Presumably it's faster too.
6381 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6383 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6384 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6385 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6386 (bidi_explicit_dir_char, bidi_level_of_next_char)
6387 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6388 Use bool for booleans, instead of int.
6389 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6390 (bidi_unshelve_cache): Adjust decls to match code.
6392 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6394 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6397 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6399 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6400 * atimer.h: Include <stdbool.h>.
6402 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6404 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6405 compile time tests instead of run time tests on systems that do
6407 (FRAME_MAC_P): Remove leftover from deleted code.
6408 * frame.c (syms_of_frame): Remove leftover from deleted code.
6410 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6412 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6414 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6416 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6417 Otherwise, the compiler complains about (A?B:C) where B is void
6418 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6419 (fontset_add): Return void, for FONTSET_ADD.
6421 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6423 * alloc.c: Use bool for booleans.
6424 (gc_in_progress, abort_on_gc)
6425 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6426 (dont_register_blocks) [GC_MALLOC_CHECK]:
6427 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6428 (check_string_bytes, make_specified_string, memory_full)
6429 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6430 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6431 (mark_stack, valid_pointer_p, make_pure_string)
6432 (Fgarbage_collect, survives_gc_p, gc_sweep):
6433 Use bool for booleans, instead of int.
6434 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6435 Remove unused local.
6436 * alloc.c (PURE_POINTER_P):
6437 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6438 * editfns.c (Fformat):
6439 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6441 * fns.c (sweep_weak_table):
6442 * lisp.h (suppress_checking, push_message, survives_gc_p)
6443 (make_pure_string, gc_in_progress, abort_on_gc):
6444 * lread.c (readchar, read1):
6445 * print.c (Fprin1_to_string):
6446 * xdisp.c (push_message):
6447 Use bool for booleans affected directly or indirectly by
6450 Make recently-introduced setters macros.
6451 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6452 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6453 (set_fontset_default, set_fontset_fallback): Rename from their
6454 upper-case counterparts, and make them functions rather than macros.
6455 This is more consistent with the other recently-introduced setters.
6456 These don't need to be inline, since they're local.
6458 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6460 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6461 the loop (Bug#12247).
6463 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6465 * lisp.h (vcopy): Use memcpy rather than our own loop.
6466 This fixes a performance regression introduced by the recent
6467 addition of vcopy. This means 'vcopy' will need to be modified
6468 for a copying collector, but that's OK. Also, tighten the
6469 checking in the assertion.
6471 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6473 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6474 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6475 non-base glyph for the width of the base character, according to
6476 what x_draw_composite_glyph_string_foreground expects.
6477 Generate WADJUST value according to composition_gstring_width's
6478 expectations, to produce correct width of the composed character.
6479 Reverse the sign of the DU offset produced by ScriptPlace.
6481 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6483 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6485 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6487 Avoid direct writes to contents member of struct Lisp_Vector.
6488 * lisp.h (vcopy): New function to copy data into vector.
6489 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6490 * fns.c (Ffillarray): Use ASET.
6491 * keyboard.c (timer_check_2): Use AREF and ASET.
6492 (append_tool_bar_item, Frecent_keys): Use vcopy.
6493 * lread.c (read_vector): Use ASET.
6494 * msdos.c (Frecent_doskeys): Use vcopy.
6495 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6496 (Finternal_merge_in_global_face): Use ASET and vcopy.
6497 * xfont.c (xfont_list_pattern): Likewise.
6499 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6501 * window.c (Fwindow_point): For the selected window always return
6502 the position of its buffer's point.
6503 (Fset_window_point): For the selected window always go in its
6504 buffer to the specified position.
6506 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6508 Setter macros for fontsets.
6509 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6510 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6511 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6514 2012-08-20 Glenn Morris <rgm@gnu.org>
6516 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6517 Don't assume that `ln -f' works.
6519 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6521 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6522 and later about non-assignments with no effect. See discussion at
6523 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6526 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6528 Inline setter functions for Lisp_Objects slots of struct specbinding.
6529 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6532 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6534 * window.c (select_window): Always make selected window's buffer
6537 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6539 Use AREF and ASET for docstrings of category tables.
6540 * category.h (CATEGORY_DOCSTRING): Use AREF.
6541 (SET_CATEGORY_DOCSTRING): Use ASET.
6542 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6544 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6546 Inline setter functions for hash table members.
6547 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6548 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6549 (set_hash_key_and_value, set_hash_index, set_hash_next)
6550 (set_hash_hash): New functions.
6551 * charset.c, fns.c: Adjust users.
6553 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6555 Inline getter and setter functions for per-buffer values.
6556 * buffer.h (per_buffer_default, set_per_buffer_default)
6557 (per_buffer_value, set_per_buffer_value): New functions.
6558 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6559 * buffer.c, data.c: Adjust users.
6561 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6563 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6565 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6567 Rely on <config.h> + <unistd.h> to declare 'environ',
6568 as gnulib does this if the system doesn't.
6569 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6570 Remove declaration. MS-Windows declares it on stdlib.h which is
6571 included by conf_post.h.
6572 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6573 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6574 * vm-limit.c: Include <unistd.h>, for 'environ'.
6576 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6577 (start_of_data): Remove decl; mem-limits.h provides it.
6579 * xdisp.c (handle_invisible_prop): Make it a bit faster
6580 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6582 2012-08-19 Chong Yidong <cyd@gnu.org>
6584 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6587 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6589 * .gdbinit: Use call instead of set when calling a function in the
6592 * data.c (set_internal): Don't use set_blv_found.
6593 (Fkill_local_variable): Likewise.
6595 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6597 * nsfont.m (ns_ascii_average_width): Ensure the string
6598 ascii_printable is initialized with a null-terminated character
6599 array. Otherwise, it can contain undesired extra characters.
6601 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6603 port new setting code to Sun C 5.8 2005/10/13
6604 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6605 Return void, not Lisp_Object. Otherwise, the compiler
6606 complains about (A?B:C) where B is void and C is Lisp_Object
6607 when compiling CHAR_TABLE_SET, due to the recent change to
6608 the API of sub_char_table_set_contents.
6610 2012-08-18 Chong Yidong <cyd@gnu.org>
6612 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6613 for the string case (Bug#3874).
6615 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6617 * buffer.h (BSET): Remove (Bug#12215).

6696 are compiled into code.
6697 (tset_param_alist): New setter function.
6699 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

6734 A few more naming-convention fixes for getters and setters.
6735 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,

6737 (set_buffer_overlays_after): Move here from buffer.h, and rename
6738 from buffer_overlays_set_after.

6766 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
6767 "set_char_table_parent (char_table, parent);".
6768 The old version was confusing because it used the same name
6769 'parent' for two different things.
6771 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6773 Functions to get and set Lisp_Object fields of buffer-local variables.

6782 font spec, make the font's attributes take precedence over
6783 directly-specified attributes.
6784 (merge_face_ref): Recognize :font.
6786 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6788 Do not use memcpy for copying intervals.
6789 * intervals.c (reproduce_interval): New function.

7440 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7441 * w32.c (init_environment): Change the default values of many
7442 environment variables in dflt_envvars[] to NULL, to avoid pushing
7443 them into environment when they were not already defined.
7444 Remove the code that deletes site-lisp subdirectories from the default
7445 value of EMACSLOADPATH, as it is no longer needed.
7446 (check_windows_init_file): Now external, not static.
7447 Use Vload_path as is, without adding anything, as this function is now
7448 called when Vload_path is already set up.
7450 * w32.h (check_windows_init_file): Add prototype.
7452 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7459 installation tree, as appropriate.
7461 * callproc.c (init_callproc_1): Call decode_env_path instead of
7462 doing its equivalent by hand.

7464 the code that sets Vexec_path run on MS-Windows.
7466 * lread.c (init_lread): Add comments to #ifdef's.
7468 * msdos.c (dos_set_window_size, IT_update_begin)

7495 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7496 Remove unnecessary pointer casts.
7497 * alloc.c (record_xmalloc): New function.
7498 * lisp.h (record_xmalloc): New decl.
7499 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7500 more like a function. This is because the pointer cast is not
7501 needed. All uses changed.
7502 * print.c (print_string, print_error_message): Avoid length recalc.
7504 Improve fix for macroexp crash with debugging (Bug#12118).
7505 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7506 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7507 not supposed to be invoked from the garbage collector.
7508 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7509 (gc_aset): New function, which is like ASET but can be
7510 used in the garbage collector.

7526 headers (most versions of MinGW w32api don't).
7527 (get_security_info, create_symbolic_link)
7528 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

7535 have the required privileges.
7536 (get_file_security_desc_by_name): Rename from
7537 get_file_security_desc.

7539 with addition of handling of symlinks and support for 'lstat'.
7540 If possible, get file's attributes and security information by
7541 handle, not by name. Produce S_IFLNK bit for symlinks, when
7542 called from 'lstat'.
7543 (stat, lstat): New functions, call 'stat_worker'.
7544 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7545 symlinks when the underlying filesystem supports them.
7547 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7549 Fix macroexp crash on Windows with debugging (Bug#12118).
7550 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7551 checking subscripts; problem introduced with the recent
7552 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7553 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7554 since it's used in non-static inline functions now.
7556 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7557 Don't assume buffer size fits in 'int'. Remove unused local.

7576 * charset.c (CHARSET_INLINE):
7577 * composite.c (COMPOSITE_INLINE):
7578 * dispnew.c (DISPEXTERN_INLINE):
7579 * sysdep.c (SYSTIME_INLINE):
7580 Define to EXTERN_INLINE, so that the corresponding functions
7581 are compiled into code.
7582 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7583 (INLINE_HEADER_END): New macros.
7584 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7604 hard-coding the path separator.
7606 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7608 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7609 This how ASET and AREF are supposed to work, and makes
7610 it easier to think about future improvements. See
7611 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7612 * charset.h (set_charset_attr): New function.

8104 the fix for 12036 would have avoided some of the problems noted in
8105 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8106 would have been more obvious.

8118 not be usable in #if. This simplifies things.
8120 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8122 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8130 Adjust to changes in lisp.h and emacs.c, by using
8131 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8132 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8133 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8134 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8135 instead of gdb_valbits.

8140 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8141 (xreload, hook-run, hookpost-run): Remove.

8174 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8175 than macros. This simplifies debugging in the usual case, since
8176 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8177 and it allows expressions involving EMACS_INT casts.
8178 * .gdbinit (xreload): Simplify by using EMACS_INT cast.

8233 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8234 This avoids crash reported by Christoph Scholtes at
8235 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8237 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8239 * nsmenu.m (Popdown_data): New struct.

8264 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8265 as it's limited by the amount of memory, not by INT_MAX.

9043 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9044 * nsterm.m (ns_term_init):
9045 Avoid the need for strncpy, by using build_string or
9046 make_unibyte_string directly. Use dtoastr, not snprintf.
9047 * process.c (Fmake_network_process): Diagnose service names that
9048 are too long, rather than silently truncating them or creating
9049 non-null-terminated names.
9050 (Fnetwork_interface_info): Likewise, for interface names.
9051 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9052 Prefer sprintf to strncat.
9053 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

9079 Optimize pure C strings initialization.
9080 * lisp.h (make_pure_string): Fix prototype.
9081 (build_pure_c_string): New function, defined as static inline. This
9082 provides a better opportunity to optimize away calls to strlen when
9083 the function is called with compile-time constant argument.
9084 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9085 argument, adjust users accordingly. Use build_pure_c_string where
9087 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9088 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9089 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9091 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9093 Avoid calls to strlen in miscellaneous functions.
9094 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9095 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9096 * lread.c (openp): Likewise.
9098 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9100 Avoid calls to strlen in path processing functions.
9101 * fileio.c (file_name_as_directory): Add comment. Change to add
9102 srclen argument and return the length of result. Adjust users

9106 Adjust users accordingly.
9107 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9109 2012-07-10 Glenn Morris <rgm@gnu.org>

9116 * s/gnu.h (DATA_START): Move definitions to configure.
9118 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9119 We include usg5-4-common.h, which defines them both.
9121 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9122 O_RDONLY already includes it).
9124 Stop ns builds setting the EMACSLOADPATH environment variable.
9125 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9126 Now it does not set EMACSLOADPATH, just returns the load-path string.
9127 * nsterm.h: Update accordingly.
9128 * lread.c [HAVE_NS]: Include nsterm.h.
9129 (init_lread) [HAVE_NS]: Use ns_load_path.

9132 2012-07-09 Glenn Morris <rgm@gnu.org>
9134 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9135 since the included bsd-common.h does so.
9137 Stop ns builds setting the EMACSPATH environment variable.
9138 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9139 (ns_init_paths): Do not set EMACSPATH.
9140 * nsterm.h (ns_exec_path): Add it.
9141 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9144 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9146 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9148 * process.c (wait_reading_process_output): 'waitchannels' was unset
9149 when read_kbd || !NILP (wait_for_cell); fix this.
9151 Add GCC-style 'const' attribute to functions that can use it.
9152 * character.h (char_resolve_modifier_mask):
9153 * keyboard.h (make_ctrl_char):
9154 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9163 Add decls with ATTRIBUTE_CONST.
9165 Minor improvements to make_formatted_string.
9166 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9167 where int is good enough, as vsprintf returns an int.
9168 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9170 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9172 Use make_formatted_string to avoid double length calculation.
9173 * lisp.h (make_formatted_string): New prototype.

9197 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9199 Move marker debugging code under MARKER_DEBUG.
9200 * marker.c (MARKER_DEBUG): Move marker debugging code under
9201 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9202 for bootstrap with --enable-checking (~3x slowdown reported
9203 by Juanma Barranquero <lekktu@gmail.com>).
9204 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9206 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9208 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9209 See <http://bugs.gnu.org/11825#29>.
9211 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9213 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9214 has no font, use the frame's font. (Bug#11813)
9215 (display_line): Add commentary about displaying truncation glyphs
9217 (produce_special_glyphs): Move here from term.c.
9219 * term.c (produce_special_glyphs): Move to xdisp.c.
9221 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9224 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9226 * xdisp.c (display_line): Avoid warning about implicit declaration
9229 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9231 * lisp.h: Remove empty conditional.
9233 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9235 * lread.c (load_path_check): Now static.
9237 Fix some minor --with-ns problems found by static checking.
9238 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9239 (x_set_font) [!HAVE_X_WINDOWS]:
9240 * image.c (xpm_load_image) [HAVE_NS]:
9241 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9242 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9243 Remove unused local.
9244 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9245 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9246 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9247 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9248 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9249 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9250 Fix pointer signedness problem.
9251 * xfaces.c (FRAME_X_FONT_TABLE):
9252 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9254 2012-07-07 Glenn Morris <rgm@gnu.org>
9256 * lread.c (load_path_check): New function, split from init_lread.
9257 (init_lread): Reorganize. Motivation:
9258 If EMACSLOADPATH is set, check/warn about that rather than the
9259 defaults, which we are not going to use. Hence we can remove
9260 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9261 Don't warn if site-lisp directories are missing.
9262 If not installed, start from a blank load-path, since
9263 PATH_LOADSEARCH refers to the eventual installation directories.
9265 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9267 Support truncation and continuation glyphs on GUI frames, when
9268 fringes are disabled. (Bug#11832)
9269 * xdisp.c (init_iterator): Get dimensions of truncation and
9270 continuation glyphs even if on GUI frames.
9271 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9272 or both, are absent.
9273 (start_display, move_it_in_display_line_to): Handle the case of a
9274 GUI frame without a fringe to display continuation or truncation
9276 (insert_left_trunc_glyphs): Support GUI frames: make sure
9277 truncation glyphs overwrite enough glyphs from the current line to
9278 have sufficient space in pixels.
9279 (display_line): Support truncation and continuation glyphs on GUI
9280 frames. If some spare pixels are left on the line after inserting
9281 the truncation glyphs, fill that space with a stretch glyph of a
9282 suitably computed width.
9284 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9285 produce_glyphs, to support GUI sessions.
9287 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9289 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9291 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9293 Do not require float-time's arg to fit in time_t (Bug#11825).
9294 This works better on hosts where time_t is unsigned, and where
9295 float-time is applied to the (negative) difference between two times.
9296 * editfns.c (decode_time_components): Last arg is now double *,
9297 not int *, and means to store all the result as a double, without
9298 worrying about whether the seconds part fits in time_t.
9299 All callers changed.
9300 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9301 All callers changed.
9302 (Ffloat_time): Do not fail merely because the specified time falls
9303 outside of time_t range.
9305 2012-07-07 Glenn Morris <rgm@gnu.org>
9307 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9308 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

9311 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9313 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9314 Update dependencies.
9316 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9318 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9320 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

9322 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9323 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9324 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9325 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9327 * xfont.c (compare_font_names): Redo to omit the need for casts.
9329 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9331 * xfns.c (Fx_change_window_property): Doc fix.
9332 * w32fns.c (Fx_change_window_property): Doc fix.
9334 * w32fns.c (Fx_window_property): Accept the same arguments as the
9335 X Windows version. Doc fix.
9336 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9338 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9339 Eli Zaretskii <eliz@gnu.org>
9341 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9342 Windows-specific code from nt/config.nt moved here.
9343 Obsolete settings removed.
9345 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9347 * process.c: Avoid unnecessary calls to gettime.
9348 (wait_reading_process_output): Don't get the time of day
9349 when gobbling data immediately and not waiting, as there's no need
9350 for it in that case. This removes a FIXME.
9352 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9354 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9355 is defined (Bug#11768).
9357 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9359 Fix marker debugging code.
9360 * marker.c (byte_char_debug_check): Do not perform the check
9361 if buffer is not multibyte.
9362 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9363 Call byte_char_debug_check with correct arguments.
9365 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9367 Compile marker debugging code only if ENABLE_CHECKING is defined.
9368 * marker.c (byte_char_debug_check, count_markers):
9369 Use only if ENABLE_CHECKING is defined.
9370 (byte_debug_flag): Remove.
9371 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9372 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9374 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9376 Avoid code repetition in marker-related functions.
9377 * marker.c (attach_marker): New function.
9378 (Fset_marker, set_marker_restricted, set_marker_both)
9379 (set_marker_restricted_both): Use it.
9380 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9381 Consistently rename charno to charpos.
9382 (marker_position): Add eassert.
9383 (marker_byte_position): Convert to eassert.

9402 * window.c (save_window_save): Likewise.
9404 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9406 Do not use Fdelete_overlay in delete_all_overlays
9407 to avoid redundant calls to unchain_overlay.
9408 * buffer.c (drop_overlay): New function.
9409 (delete_all_overlays, Fdelete_overlay): Use it.
9410 * minibuf.c (get_minibuffer): Fix comment.
9412 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9414 Port to OpenBSD 5.1 amd64.
9415 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9416 This is needed for OpenBSD, and should be harmless on all BSD systems.
9417 Also, include <sys/sysctl.h>, as it should be available on all
9418 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9419 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9420 use p_pid member, not kp_proc.pid.
9422 2012-07-06 Glenn Morris <rgm@gnu.org>
9424 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9426 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9428 More xmalloc and related cleanup.
9429 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9430 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
9431 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
9432 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
9433 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
9434 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
9435 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9436 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9437 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9439 Omit needless casts involving void * pointers and allocation.
9440 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9441 as the former is more robust if P's type is changed.
9442 Prefer xzalloc to xmalloc + memset 0.
9443 Simplify malloc-or-realloc to realloc.
9444 Don't worry about xmalloc returning a null pointer.
9445 Prefer xstrdup to xmalloc + strcpy.
9446 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9448 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9449 alloca of a constant.
9451 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9453 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9454 hscroll is larger than the line width. Fixes long and futile
9455 looping inside extend_face_to_end_of_line (on a TTY) producing
9456 glyphs that are not needed and thrown away.
9458 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9460 * marker.c (set_marker_restricted_both): Simplify by using
9463 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9473 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9474 followed by gtk_box_set_homogeneous (Bug#11768).
9475 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9476 (update_theme_scrollbar_width, xg_create_scroll_bar):
9477 Use gtk_scrollbar_new (Bug#11768).
9478 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9486 * xdisp.c (window_hscroll_limited): New function.
9487 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9488 coordinates when window's hscroll is set to insanely large
9491 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9493 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9494 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9496 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9499 * lisp.h (xzalloc): New prototype. Omit needless casts.

9554 * fileio.c (time_error_value): Check the right error number.
9555 Problem reported by Troels Nielsen in
9556 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9558 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9560 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9561 This should be fixed in a better way; see Eli Zaretskii in
9562 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9563 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9565 * fileio.c (time_error_value): Rename from special_mtime.
9566 The old name's problems were noted by Eli Zaretskii in
9567 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9569 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9570 This variable's comment says Emacs needs at least one GDB-visible
9571 symbol of type enum pvec_type, to work around GDB problems.
9572 The symbol's value doesn't matter.
9574 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9575 that causes compilation to fail on pre-C99 compilers.
9577 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9579 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9580 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9582 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9584 * buffer.c (init_buffer_once): Fix initialization of
9585 headers for buffer_defaults and buffer_local_symbols.
9586 Reported by Juanma Barranquero <lekktu@gmail.com>.
9588 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9590 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9591 * lisp.h (enum pvec_type): Use fewer bits.
9592 (PSEUDOVECTOR_SIZE_BITS): New constant.
9593 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9594 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9595 change in pvec_type.
9596 (PSEUDOVECTOR_TYPEP): New macro.
9597 (TYPED_PSEUDOVECTORP): Use it.
9598 * fns.c (internal_equal): Adapt code to extract pvectype.

9600 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9601 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9602 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9603 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9604 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9605 abusing vector->header.next.nbytes.
9606 (live_vector_p): Use PVEC_TYPE.
9607 (mark_object): Adapt code to extract pvectype. Use switch.
9609 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9611 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9612 Tighten new eassert a bit.
9614 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9616 Fix compilation with --enable-gcc-warnings and -O1
9618 * doprnt.c (doprnt): Change type of tem to int, initialize
9619 to avoid compiler warning. Add eassert.
9620 * search.c (simple_search): Initialize match_byte to avoid
9621 compiler warning. Add eassert.
9623 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9625 Avoid weird behavior with large horizontal scrolls.
9626 Without this change, for example, large hscroll values would
9627 mess up Emacs's display on Fedora 15 x86, presumably due to
9628 overflows in int calculations in the display code.
9629 Also, if buffers had long lines, Emacs would freeze.
9630 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9631 (set_window_hscroll): New function, containing the old guts of
9632 Fset_window_hscroll. Return the clipped value.
9633 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9634 This avoids the need to check against PTRDIFF_MAX.
9636 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9638 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9640 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9642 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9644 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9645 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9646 since GCC 4.4.6 issues a bogus warning for them.
9648 Fix bugs in file timestamp newness comparisons.
9649 * fileio.c (Ffile_newer_than_file_p):
9650 * lread.c (Fload): Use full timestamp resolution of files,
9651 not just the 1-second resolution, so that files that are only
9652 slightly newer still count as newer.
9653 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9654 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9656 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9658 * fileio.c: Improve handling of file time marker. (Bug#11852)
9659 (special_mtime): New function.
9660 (Finsert_file_contents, Fverify_visited_file_modtime):
9661 Use it to set special mtime values consistently.
9663 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9665 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9666 marker for non-existing file. (Bug#11852)
9668 2012-07-03 Glenn Morris <rgm@gnu.org>
9670 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9671 and did not make it into globals.h).
9673 2012-07-03 Tom Tromey <tromey@redhat.com>
9675 * window.c (Fset_window_margins, Fset_window_fringes)
9676 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9677 * textprop.c (Fprevious_property_change): No longer static.
9678 * syntax.c (Fsyntax_table_p): No longer static.
9679 * process.c (Fget_process, Fprocess_datagram_address): No longer

9700 * intervals.h: Remove EXFUNs.
9701 * fontset.h: Remove EXFUN.

9707 * window.h: Remove EXFUNs.

9709 * xterm.h: Remove EXFUN.
9711 2012-07-03 Glenn Morris <rgm@gnu.org>
9713 * lisp.h (Frandom): Make it visible to C.
9714 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9715 buffer for invisible buffers. (Bug#1229)
9717 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9719 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9720 values which aren't power of 2.
9721 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9722 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9725 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9727 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9729 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9731 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9733 * alloc.c (allocate_vector_block): Remove redundant
9734 calls to mallopt if DOUG_LEA_MALLOC is defined.
9735 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9736 avoid calls to mallopt if zero_vector is returned.
9738 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9740 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9741 is enabled, avoid dereferencing NULL current_sblock if
9744 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9746 Cleanup basic buffer management.
9747 * buffer.h (struct buffer): Change layout to use generic vector
9748 marking code. Fix some comments. Change type of 'clip_changed'
9749 to bitfield. Remove unused #ifndef old.
9750 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9751 (GET_OVERLAYS_AT): Fix indentation.
9752 (for_each_per_buffer_object_at): New macro.

9756 * alloc.c (allocate_buffer): Adjust to match new layout of
9757 struct buffer. Fix comment.
9758 (mark_overlay): New function.

9761 (mark_object): Use it. Adjust marking of misc objects
9762 and related comments.
9764 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9766 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9767 wrapper that is not needed because the wrapped code is a no-op (zero
9768 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9769 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9771 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9773 * alloc.c (mark_buffer): Simplify. Remove prototype.
9774 (mark_object): Add comment. Reorganize marking of vector-like
9775 objects. Use CHECK_LIVE for all vector-like objects except buffers
9776 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9777 Avoid redundant calls to mark_vectorlike for bool vectors.
9779 2012-06-30 Glenn Morris <rgm@gnu.org>
9781 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9783 * epaths.in (PATH_SITELOADSEARCH): New.
9784 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9785 This is rather than relying on --enable-locallisppath elements
9786 having "site-lisp" in their names. (Bug#10208#25, 11658)
9788 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9790 * w32proc.c (sys_select): Accept and ignore one more argument.
9792 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9794 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9795 (pselect) [!MS_DOS]: Redirect to sys_select.
9797 * sysdep.c: Don't include dos.h and dosfns.h.
9799 * process.c (sys_select):
9800 * msdos.c (sys_select): Accept one more argument and ignore it.
9802 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9803 adapt data types and code to that.
9806 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9807 which clashes with the gnulib function of the same name.
9809 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9811 * font.c (font_style_to_value, font_style_symbolic)
9812 (font_prop_validate_style): Add type checks for values in
9815 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9817 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9820 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9822 * xdisp.c (try_window_id): Undo last change.
9824 * w32.c (getwd): Adjust commentary about startup_dir.
9825 (init_environment): Always call sys_access, even in non-MSVC
9826 builds. Don't chdir to the directory of the Emacs executable.
9827 This undoes code from 1997 which was justified by the need to
9828 "avoid conflicts when removing and renaming directories". But its
9829 downside was that every relative file name was being interpreted
9830 relative to the directory of the Emacs executable, which can never
9831 be TRT. In particular, it broke sys_access when called with
9832 relative file names.
9833 (sys_access): Map GetLastError to errno.
9835 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9837 * window.h (struct window): Change type of 'fringes_outside_margins'

9841 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9844 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9846 * gnutls.c (emacs_gnutls_handshake):
9847 Add QUIT to make the loop interruptible.
9849 2012-06-29 Glenn Morris <rgm@gnu.org>
9851 * charset.c (init_charset): Make lack of etc/charsets fatal.
9853 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9855 * editfns.c (region_limit): Fix type mismatch.
9857 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9859 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9860 undefined. Convert from xassert to eassert.
9861 * nsmenu.m: Convert from xassert to eassert.
9862 * nsterm.m: Likewise.
9864 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9866 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9868 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9870 Avoid integer overflow on scroll-left and scroll-right.
9871 * window.c (HSCROLL_MAX): New macro.
9872 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9873 overflow when requested scroll falls outside ptrdiff_t range.
9875 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9877 * window.h (struct window): Change type of 'hscroll',
9878 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9879 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9880 Adjust users accordingly.
9881 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9882 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9883 from EMACS_INT to ptrdiff_t.
9884 (make_window): Omit redundant initialization.
9886 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9890 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9892 * window.h (struct window): Change type of 'use_time' and
9893 'sequence_number' from Lisp_Object to int.

9902 enabled with --enable-checking=[all,glyphs] configure option.
9903 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9904 adjust comments accordingly.

9955 avoid GCC warning about unused macro.
9957 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9959 * alloc.c (allocate_string): Omit intervals initialization.
9960 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9961 as in make_pure_string and make_pure_c_string.
9963 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9965 * alloc.c (allocate_string): Fix last change.
9967 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9986 when building with Clang.
9988 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

10017 * alloc.c: Remove build_string.
10018 * lisp.h: Define build_string as static inline. This provides
10019 a better opportunity to optimize away calls to strlen when the
10020 function is called with compile-time constant argument.
10021 * image.c (imagemagick_error): Convert to build_string.
10022 * w32proc.c (sys_spawnve): Likewise.
10023 * xterm.c (x_term_init): Likewise.
10025 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10027 Use sprintf return value instead of invoking strlen on result.
10028 In the old days this wasn't portable, since some sprintf
10029 implementations returned char *. But they died out years ago and
10030 Emacs already assumes sprintf returns int.
10031 Similarly for float_to_string.
10032 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10033 * ccl.c (ccl_driver):

10037 * print.c (print_object):
10038 * xdisp.c (message_dolog):
10039 * xfns.c (syms_of_xfns):
10040 Use sprintf or float_to_string result to avoid need to call strlen.
10041 * data.c (Fnumber_to_string):
10042 Use make_unibyte_string, since the string must be ASCII.
10043 * lisp.h, print.c (float_to_string): Now returns int length.
10044 * term.c (produce_glyphless_glyph):
10045 Use sprintf result rather than recomputing it.
10047 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10048 * Makefile.in (ALL_CFLAGS):
10049 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10050 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10052 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10054 * dispextern.h (xstrcasecmp): Define to library function
10055 strcasecmp if available.
10056 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10058 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

10071 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10073 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10074 sprintf already null-terminates its output.
10076 * xfns.c (x_window): Remove redundant cast.
10078 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10080 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10081 `const char *' to `char *' to avoid compiler warning.
10083 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10085 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10086 instead of truncating it to 63 (admittedly a generous limit).
10088 * process.c: Fix spelling and caps in comments.
10090 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10092 * emacs.c (setpgrp): Remove definition, unused.

10106 * s/ms-w32.h (struct timespec): Definition moved from
10107 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10109 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10139 Remove unnecessary forward decls.
10141 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10143 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10144 * lisp.h (WAIT_READING_MAX): New macro.
10145 * dispnew.c (Fsleep_for, sit_for):
10146 * keyboard.c (kbd_buffer_get_event):
10147 * process.c (Faccept_process_output):
10148 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10149 This improves on the previous patch, which introduced a bug
10150 when time_t is unsigned and as wide as intmax_t.
10151 See <http://bugs.gnu.org/9000#51>.
10153 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10155 * dispnew.c (sit_for, Fsleep_for):
10156 * keyboard.c (kbd_buffer_get_event):

10160 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
10162 * makefile.w32-in: Update dependencies.

10171 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10173 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10174 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10176 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10178 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10179 last argument of make_unibyte_string.
10181 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10182 language ID in the event parameters.
10184 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10185 event.code, not the obscure "character set ID".
10187 2012-06-23 Chong Yidong <cyd@gnu.org>
10189 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10212 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10213 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10214 Don't assume EMACS_TIME and struct timeval are the same type.
10216 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10218 Support higher-resolution time stamps (Bug#9000).
10219 The time stamps are only nanosecond-resolution at the C level,
10220 since that's the best that any real-world system supports now.
10221 But they are picosecond-resolution at the Lisp level, as that's
10222 easy, and leaves room for future OS improvements.
10224 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10227 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10228 Don't get current time unless it's needed.
10230 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10231 now provides it if it's absent.
10232 (start_atimer): Port to higher-res time stamps.
10233 Check for time stamp overflow. Don't get current time more
10234 often than is needed.
10236 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10237 Include systime.h, not time.h.
10238 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10240 * dired.c: Include stat-time.h.
10241 (Ffile-attributes): File times now have higher resolution.
10243 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10244 (struct image): Timestamp now has higher resolution.
10246 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10247 has at least microseconds now. All uses removed.
10248 (update_frame, update_single_window, update_window, update_frame_1)
10249 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10250 (duration_to_sec_usec): Remove; no longer needed.
10252 * editfns.c (time_overflow): Now extern.
10253 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10254 (float-time, Fformat_time_string, Fcurrent_time_string)

10257 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10258 (decode_time_components, lisp_seconds_argument): New functions.
10259 (make_time): Now static.
10260 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10261 Report an error if the time is invalid, rather than having the caller
10264 * fileio.c: Include <stat-time.h>
10265 (Fcopy_file): Copy higher-resolution time stamps.
10266 Prefer to set the time stamp via a file descriptor if that works.
10267 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10268 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10269 (Fvisited_file_modtime, Fset_visited_file_modtime):
10270 Support higher-resolution time stamps.
10272 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10274 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10276 * image.c (prepare_image_for_display, clear_image_cache)
10277 (lookup_image): Port to higer-resolution time stamps.
10279 * keyboard.c (start_polling, bind_polling_period):
10280 Check for time stamp overflow.
10281 (read_char, kbd_buffer_get_event, timer_start_idle)
10282 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10283 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10284 Port to higher-resolution time stamps. Do not assume time_t is signed.
10285 (decode_timer): New function. Timers are now vectors of length 9,
10286 not 8, to accommodate the picosecond component.
10287 (timer_check_2): Use it.
10289 * nsterm.m (select_timeout, timeval_subtract): Remove.
10290 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10291 as they're a bit more accurate and handle overflow better.
10292 (ns_select): Change prototype to be compatible with pselect.
10293 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10294 * nsterm.h (ns_select): Adjust prototype.
10296 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10297 us-resolution time stamps.
10298 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10300 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10302 * lisp.h (time_overflow): New decl.
10303 (wait_reading_process_output): First arg is now intmax_t, not int,
10304 to accommodate larger waits.
10306 * process.h (struct Lisp_Process.read_output_delay):
10307 Now counts nanoseconds, not microseconds.
10308 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10310 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10311 (wait_reading_process_output):
10312 Port to ns-resolution time stamps.
10313 (Faccept_process_output, wait_reading_process_output):
10314 Check for time stamp overflow. Do not assume time_t is signed.
10315 (select_wrapper): Remove; we now use pselect.
10316 (Fprocess_attributes): Now generates ns-resolution time stamps.
10318 * sysdep.c: Include utimens.h. Don't include utime.h
10319 or worry about struct utimbuf; gnulib does that for us now.
10320 (gettimeofday): Remove; gnulib provides a substitute.
10321 (make_timeval): New function.
10322 (set_file_times): Now sets ns-resolution time stamps.
10323 New arg FD; all uses changed.
10324 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10325 (system_process_attributes):
10326 Now returns ns-resolution time stamp. All uses changed.
10327 Check for time stamp overflow.
10329 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10330 provides a substitute now.
10332 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10333 since it guarantees struct timespec.
10334 (EMACS_TIME): Now struct timespec, so that we can support
10335 ns-resolution time stamps.
10336 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10337 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10338 (EMACS_USECS): Remove.
10339 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10340 so multiply the arg by 1000 before storing it.
10341 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10343 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10344 Port to ns-resolution time stamps.
10345 (EMACS_TIME_NEG_P): Remove; replaced by....
10346 (EMACS_TIME_SIGN): New macro.
10347 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10348 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10349 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10350 (make_timeval, make_lisp_time, decode_time_components): New decls.
10351 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10352 that it mishandled time_t overflow. You can't compare by subtracting!
10353 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10354 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10356 * term.c: Include <sys/time.h>.
10357 (timeval_to_Time): New function, for proper overflow wraparound.
10358 (term_mouse_position, term_mouse_click): Use it.
10360 * undo.c (record_first_change): Support higher-resolution time stamps
10361 in the undo buffer.
10362 (Fprimitive_undo): Use them when restoring time stamps.
10364 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10365 (w32_get_internal_run_time):
10366 Port to higher-resolution Emacs time stamps.
10367 (ltime): Now accepts single 64-bit integer, as that's more convenient
10370 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10372 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10373 for compatibility with pselect. Support ns-resolution time stamps.
10375 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10377 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10378 Check for time stamp overflow, and support ns-resolution time stamps.
10380 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10381 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10382 (timeval_subtract): Remove; no longer needed.
10383 (XTflash, XTring_bell, x_wait_for_event):
10384 Port to ns-resolution time stamps. Don't assume time_t is signed.
10386 2012-06-22 Chong Yidong <cyd@gnu.org>
10388 * xdisp.c (x_consider_frame_title): Revert last change.
10390 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10392 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10393 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10394 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10395 staticidx goes up to 1597 out of 1600 = 0x640.)
10397 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10399 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10400 Otherwise, the umask might be mistakenly 0 while handling input signals.
10402 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10404 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10410 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10411 access to `contents' member of Lisp_Vector objects with AREF and ASET
10414 2012-06-19 Chong Yidong <cyd@gnu.org>
10416 * frame.c (delete_frame): When selecting a frame on a different
10417 text terminal, do not alter the terminal's top-frame.
10419 * xdisp.c (format_mode_line_unwind_data): Record the target

10872 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10873 Convert pctcpu and pctmem to Lisp float properly.
10874 Let the compiler fold better, as 100.0/0x8000 is exact.
10876 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10878 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10881 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
10883 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
10885 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10887 For a 'struct window', replace some Lisp_Object fields to
10888 bitfields where appropriate, remove unused fields.
10889 * window.h (struct window): Remove unused 'last_mark_x' and
10890 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10891 change its type from Lisp_Object to bitfield.
10892 Change type of 'force_start', 'optional_new_start',
10893 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10894 fields from Lisp_Object to bitfield. Adjust users accordingly.
10896 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10898 Pacify gcc -Wdouble-precision when using Xaw.
10899 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10900 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10901 Use 'float' consistently, rather than 'float' in most places
10902 and 'double' in a couple of places.
10904 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10906 * xdisp.c (handle_stop): Detect whether we have overlay strings
10907 loaded by testing it->current.overlay_string_index to be
10908 non-negative, instead of checking whether n_overlay_strings is
10909 positive. (Bug#11587)
10911 2012-05-31 Chong Yidong <cyd@gnu.org>
10913 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10915 * doc.c (Fsubstitute_command_keys): Doc fix.
10917 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10919 * search.c (search_buffer): Remove calls to
10920 r_alloc_inhibit_buffer_relocation, as it is now called by
10921 maybe_unify_char, which was the cause of relocation of buffer text
10924 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10926 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10927 for the duration of call to load_charset, to avoid problems with
10928 callers of maybe_unify_char that access buffer text through C
10931 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10932 decrement the inhibition flag, instead of just setting or
10935 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10937 Remove obsolete '#define static' cruft.
10938 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10939 This #undef was "temporary" in 2000; it is no longer needed
10940 now that '#define static' has gone away.
10941 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10942 (gray_bitmap_bits): Remove; no longer needed.
10943 All uses replaced with definiens.
10944 * xterm.c: Include "bitmaps/gray.xbm".
10946 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10948 Clean up __executable_start, monstartup when --enable-profiling.
10949 The following changes affect the code only when profiling.
10950 * dispnew.c (__executable_start): Rename from safe_bcopy.
10951 Define only on platforms that need it.
10952 * emacs.c: Include <sys/gmon.h> when profiling.
10953 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10954 (__executable_start): Remove decl, since lisp.h does it now.
10955 (safe_bcopy): Remove decl; no longer has that name.
10956 (main): Coalesce #if into single bit of code, for simplicity.
10957 Cast pointers to uintptr_t, since standard libraries want integers
10959 * lisp.h (__executable_start): New decl.
10961 2012-05-31 Glenn Morris <rgm@gnu.org>
10963 * image.c (Fimagemagick_types): Doc fix.
10965 2012-05-30 Jim Meyering <meyering@redhat.com>
10967 * callproc.c (Fcall_process_region): Include directory component
10968 in mkstemp error message (Bug#11586).
10970 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10972 * alloc.c, lisp.h (make_pure_vector): Now static.
10974 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10976 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10977 Move to byte-run.el.
10978 (Fautoload): Do the hash-doc more carefully.
10979 * data.c (Fdefalias): Purify definition, except for keymaps.
10980 (Qdefun): Move from eval.c.
10981 * lisp.h (Qdefun): Remove.
10982 * lread.c (read1): Tiny simplification.
10984 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10986 Do not create empty overlays with the evaporate property (Bug#9642).
10987 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10988 Bug#9642, but explicitly check that the buffer the overlay would
10989 be moved to is live and rearrange lines to make sure that errors
10990 will not put the overlay in an inconsistent state.
10991 (Fdelete_overlay): Cosmetics.
10993 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10995 * w32term.c (my_bring_window_to_top): New function.
10996 (x_raise_frame): Use handle returned by DeferWindowPos, which
10997 could be different from the original one.
10998 Call my_bring_window_to_top instead of my_set_foreground_window.
11001 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11002 by calling BringWindowToTop.
11004 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

11007 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11009 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11010 This avoids undefined behavior that might cause the eassert
11011 to not catch an out-of-range value.
11013 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11015 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11016 Update dependencies.
11018 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11020 * bidi.c (bidi_mirror_char): Fix last change.
11022 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11024 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11025 when referring to sectname field in printf format.
11027 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11029 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11030 Only r_alloc_inhibit_buffer_relocation needed to be added;
11031 the others were already declared.
11033 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11034 before checking whether it's out of range. Put the check inside
11036 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11038 2012-05-27 Ken Brown <kbrown@cornell.edu>
11040 * callproc.c (Fcall_process): Restore a line that was accidentally
11041 commented out in the 2011-02-13 change (bug#11547).
11043 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11045 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11046 defined on ralloc.c.
11048 * buffer.c [REL_ALLOC]: Remove prototypes of
11049 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11050 they are now on lisp.h.
11052 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11054 * search.c (search_buffer): Use it to inhibit relocation of buffer
11055 text while re_search_2 is doing its job, because re_search_2 is
11056 passed C pointers to buffer text. (Bug#11519)
11058 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11059 Update value to 24.
11061 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11062 state after an additional call to move_it_in_display_line_to, keep
11063 the values of it->max_ascent and it->max_descent found for the
11065 (pos_visible_p): Revert the comparison against bottom_y to what it
11066 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11069 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11071 Fix coding-related core dumps with gcc -ftrapv.
11072 The code was computing A - B, where A and B are pointers, and B is
11073 random garbage. This can lead to core dumps on platforms that
11074 have special pointer registers, and it also leads to core dumps on
11075 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11076 A - B only when B is initialized properly.
11077 * coding.c (coding_set_source, coding_set_destination): Return void.
11078 (coding_change_source, coding_change_destinations): New functions,
11079 with the old behaviors of coding_set_source and coding_set_destination.
11080 All callers that need an offset changed to use these new functions.
11082 2012-05-26 Glenn Morris <rgm@gnu.org>
11084 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11086 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11088 Extend mouse support on W32 text-mode console.
11089 * xdisp.c (draw_row_with_mouse_face):
11090 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11092 * w32console.c: Include window.h.
11093 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11095 (initialize_w32_display): Initialize mouse-highlight data.
11097 * w32inevt.c: Include termchar.h and window.h.
11098 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11099 moves, call note_mouse_highlight. If help_echo changed, call
11100 gen_help_event to produce help-echo message in the echo area.
11101 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11104 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11106 * lread.c (read1): Simplify slightly to avoid an overflow warning
11107 with GCC 4.7.0 on x86-64.
11109 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11111 * bidi.c (bidi_mirror_char): Revert last change: an int is
11112 definitely wide enough here.
11114 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11116 Fix integer width and related bugs (Bug#9874).
11117 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11118 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11119 (string_bytes, check_sblock, allocate_string_data):
11120 (compact_small_strings, Fmake_bool_vector, make_string)
11121 (make_unibyte_string, make_multibyte_string)
11122 (make_string_from_bytes, make_specified_string)
11123 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11124 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11126 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11127 (allocate_pseudovector):
11128 Use int, not EMACS_INT, where int is wide enough.
11129 (inhibit_garbage_collection, Fgarbage_collect):
11130 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11131 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11132 int might not be wide enough.
11133 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11134 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11135 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11136 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11137 (bidi_level_of_next_char, bidi_move_to_visually_next):
11138 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11139 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11140 (Fkill_buffer, Fset_buffer_major_mode)
11141 (advance_to_char_boundary, Fbuffer_swap_text)
11142 (Fset_buffer_multibyte, overlays_at, overlays_in)
11143 (overlay_touches_p, struct sortvec, record_overlay_string)
11144 (overlay_strings, recenter_overlay_lists)
11145 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11146 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11147 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11148 (Foverlay_recenter, last_overlay_modification_hooks_used)
11149 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11150 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11151 (validate_region): Omit unnecessary test for b <= e,
11152 since that's guaranteed by the previous test.
11153 (adjust_overlays_for_delete): Avoid pos + length overflow.
11154 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11155 (report_overlay_modification):
11156 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11157 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11158 Omit pointer cast, which isn't needed anyway, and doesn't work
11159 after the EMACS_INT -> ptrdiff_t change.
11160 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11161 * buffer.h: Adjust decls to match defn changes elsewhere.
11162 (struct buffer_text, struct buffer):
11163 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11164 Use EMACS_INT, not int, where int might not be wide enough.
11165 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11166 not int, to avoid needless 32-bit limit on 64-bit hosts.
11167 (exec_byte_code): Use tighter memory-full test, one that checks
11168 for alloca overflow. Don't compute the address of the object just
11169 before an array, as that's not portable. Use EMACS_INT, not
11170 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11171 * callint.c (Fcall_interactively):
11172 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11173 * callproc.c (call_process_kill, Fcall_process):
11174 Don't assume pid_t fits into an Emacs fixnum.
11175 (call_process_cleanup, Fcall_process, child_setup):
11176 Don't assume pid_t fits into int.
11177 (call_process_cleanup, Fcall_process, delete_temp_file)
11178 (Fcall_process_region):
11179 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11180 (Fcall_process): Simplify handling of volatile integers.
11181 Use int, not EMACS_INT, where int will do.
11182 * casefiddle.c (casify_object, casify_region, operate_on_word)
11183 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11184 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11185 (casify_object): Avoid integer overflow when overallocating buffer.
11186 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11187 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11188 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11189 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11190 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11191 integers are now checked earlier. All uses replaced with XINT.
11193 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11194 For CCL_MapSingle, check that content and value are in int range.
11195 (ccl_driver, Fregister_code_conversion_map):
11196 Check that Vcode_version_map_vector is a vector.
11197 (resolve_symbol_ccl_program): Check that vector header is in range.
11198 Always copy the vector, so that we can check its contents reliably
11199 now rather than having to recheck each instruction as it's being
11200 executed. Check that vector words fit in 'int'.
11201 (ccl_get_compiled_code, Fregister_ccl_program)
11202 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11203 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11204 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11205 contents are in range.
11206 (Fccl_execute_on_string): Check that status is in range.
11207 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11208 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11209 Accept and return EMACS_INT, not int, because callers can pass values
11210 out of 'int' range.
11211 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11212 (multibyte_chars_in_text, parse_str_as_multibyte)
11213 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11214 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11215 (string_escape_byte8, Fget_byte):
11216 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11217 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11218 avoid mishandling large integers.
11219 * character.h: Adjust decls to match defn changes elsewhere.
11220 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11221 (Ffind_charset_region):
11222 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11223 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11224 (load_charset_map_from_vector, Fdefine_charset_internal):
11225 Don't assume fixnum fits in int.
11226 (load_charset_map_from_vector, Fmap_charset_chars):
11227 Remove now-unnecessary CHECK_NATNUMs.
11228 (Fdefine_charset_internal): Check ranges here, more carefully.
11229 Don't rely on undefined behavior with signed left shift overflow.
11230 Don't assume unsigned int fits into fixnum, or that fixnum fits
11231 into unsigned int. Don't require max_code to be a valid fixnum;
11232 that's not true for gb10830 4-byte on a 32-bit host. Allow
11233 invalid_code to be a cons, for the same reason. Require code_offset
11234 to be a character. Avoid int overflow if max_char is close
11236 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11237 this is intended anyway and avoids some undefined behavior.
11238 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11239 INDEX_TO_CODE_POINT, as that's what it expects.
11240 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11241 * charset.h (DECODE_CHAR): Return int, not unsigned;
11242 this is what was intended anyway, and it avoids undefined behavior.
11243 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11244 integer-overflow issues.
11245 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11246 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11247 where the argument is EMACS_INT, and this behavior is not intended.
11248 * chartab.c (Fmake_char_table, Fset_char_table_range)
11249 (uniprop_get_decoder, uniprop_get_encoder):
11250 Don't assume fixnum fits in int.
11251 * cmds.c (move_point): New function, that does the gist of
11252 Fforward_char and Fbackward_char, but does so while checking
11253 for integer overflow more accurately.
11254 (Fforward_char, Fbackward_char): Use it.
11255 (Fforward_line, Fend_of_line, internal_self_insert)
11256 (internal_self_insert):
11257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11258 Fix a FIXME, by checking for integer overflow when calculating
11259 target_clm and actual_clm.
11260 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
11261 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

11952 Use VAL_MAX, not VALBITS, in #if.
11953 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11954 (EMACS_UINT): Define unconditionally now.
11955 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11956 (BITS_PER_EMACS_INT): New constants, replacing
11957 what used to be in config.h, but not useful in #if.
11958 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11959 define them any more.
11960 (VAL_MAX): New macro.
11962 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11963 BITS_PER_EMACS_INT, in #if.
11964 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11965 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11966 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11967 * s/ms-w32.h (DATA_START):
11968 Move here from removed file m/intel386.h.
11969 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11970 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11972 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11974 Assume C89 or later.
11975 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11976 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11978 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
11979 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11980 * textprop.c, tparam.c (NULL): Remove.
11981 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11982 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11983 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11984 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11985 * xterm.c (input_signal_count): Assume volatile works.
11987 2012-05-21 Ken Brown <kbrown@cornell.edu>
11989 * xgselect.c (xg_select): Fix first argument in call to 'select'
11992 2012-05-20 Ken Brown <kbrown@cornell.edu>
11994 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11995 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11997 2012-05-19 Ken Brown <kbrown@cornell.edu>
11999 * xfns.c (x_in_use): Remove `static' qualifier.
12000 * xterm.h (x_in_use): Declare.
12001 * xgselect.c: Include xterm.h.
12002 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12003 and `display_arg' (bug#9754).
12005 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12007 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12009 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12010 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12012 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12014 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12016 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12017 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12019 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12020 reference to image_cache->refcount.
12021 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12023 2012-05-17 Juri Linkov <juri@jurta.org>
12025 * search.c (Fword_search_regexp, Fword_search_backward)
12026 (Fword_search_forward, Fword_search_backward_lax)
12027 (Fword_search_forward_lax): Move functions to isearch.el
12028 (bug#10145, bug#11381).
12030 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12032 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12034 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12036 * lread.c (init_obarray): Declare Qt and Qnil as special.
12038 2012-05-14 Glenn Morris <rgm@gnu.org>
12040 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12041 Put "libexec" before "bin", for the sake of init_callproc_1.
12043 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12045 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12047 * unexaix.c: Port to more-recent AIX compilers.
12048 (report_error, report_error_1, make_hdr, copy_sym)
12049 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12050 Make arguments const char *, not char *, to avoid violations of C
12051 standard and to fix some AIX warnings reported by Gilles Pion.
12053 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12055 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12056 already have overlays loaded.
12057 (handle_single_display_spec): Before returning without displaying
12058 fringe bitmap, synchronize the bidi iterator with the main display
12059 iterator, by calling iterate_out_of_display_property.
12060 (iterate_out_of_display_property): Detect buffer iteration by
12061 testing that it->string is a Lisp string.
12062 (get_next_display_element): When the current object is exhausted,
12063 and there's something on it->stack, call set_iterator_to_next to
12064 proceed with what's on the stack, instead of returning zero.
12065 (set_iterator_to_next): If called at the end of a Lisp string,
12066 proceed to consider_string_end without incrementing string
12067 position. Don't increment display vector index past the end of
12068 the display vector. (Bug#11417)
12069 (pos_visible_p): Don't report a position visible when move_it_to
12070 stopped at the last line of window, which happens to be scanned
12071 backwards by the bidi iteration. (Bug#11464)
12073 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12075 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12076 and right-margin display specs even if the spec is invalid or we
12077 are on a TTY, and thus unable to display on the fringes.
12078 That's because the text with the property will not be displayed anyway,
12079 so we need to signal to the caller that this is a "replacing"
12080 display spec. This fixes display when the spec is invalid or we
12083 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12085 * unexaix.c (make_hdr): Fix typo in prototype.
12086 This bug broke the build on AIX. Problem reported by Gilles Pion.
12088 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12090 * keyboard.c (kbd_buffer_get_event): Read special events also in
12091 batch mode. (Bug#11415)
12093 2012-05-12 Glenn Morris <rgm@gnu.org>
12095 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12097 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12099 * lisp.mk (lisp): Add newcomment.elc.
12101 2012-05-12 Glenn Morris <rgm@gnu.org>
12103 * Makefile.in (MKDIR_P): New, set by configure.
12104 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12106 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12108 Remove unused function hourglass_started.
12109 * dispextern.h (hourglass_started):
12110 * w32fns.c (hourglass_started):
12111 * xdisp.c (hourglass_started): Remove.
12113 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12115 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12116 Update dependencies.
12118 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12120 * xgselect.c (xg_select): Put maxfds+1 into a var.
12121 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12123 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12125 2012-05-10 Dave Abrahams <dave@boostpro.com>
12127 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12128 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12130 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12132 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12133 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12134 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12135 Initialize xd_registered_buses.
12137 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12139 Untag more efficiently if USE_LSB_TAG.
12140 This is based on a proposal by YAMAMOTO Mitsuharu in
12141 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12142 For an admittedly artificial (nth 8000 longlist) benchmark on
12143 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12144 Emacs's overall text size by 1%.
12145 * lisp.h (XUNTAG): New macro.
12146 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12147 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12148 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12149 * eval.c (Fautoload):
12150 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12151 * frame.h (XFRAME): Use XUNTAG.
12153 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12154 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12155 Remove unportable assumptions about print widths of types like
12157 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12158 intptr_t when converting between pointer and integer, to avoid GCC
12159 warnings about wrong width.
12161 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12163 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12164 stack for each reader_thread, instead of defaulting to 8MB
12165 determined by the linker. This avoids failures in creating
12166 subprocesses on Windows 7, see the discussion in this thread:
12167 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12169 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12171 Fix up display of the *Minibuf-0* buffer in the mini window.
12172 * keyboard.c (read_char): Don't clear the echo area if there's no
12174 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12175 contents of *Minibuf-0*) if there's no message displayed in its stead.
12177 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12179 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12182 2012-05-06 Chong Yidong <cyd@gnu.org>
12184 * lisp.mk (lisp): Update.
12186 2012-05-05 Jim Meyering <meyering@redhat.com>
12188 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12190 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12192 * data.c (PUT_ERROR): New macro.
12193 (syms_of_data): Use it. Add new error type `user-error'.
12194 * undo.c (user_error): New function.
12195 (Fprimitive_undo): Use it.
12196 * print.c (print_error_message): Adjust print style for `user-error'.
12197 * keyboard.c (user_error): New function.
12198 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12200 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12202 Do not limit current-time-string to years 1000..9999.
12203 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12204 (Fcurrent_time_string): Support any year that is supported by the
12205 underlying localtime representation. Don't use asctime, as it
12206 has undefined behavior for years outside the range -999..9999.
12208 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12210 Fix race conditions involving setenv, gmtime, localtime, asctime.
12211 Without this fix, interrupts could mess up code that uses these
12212 nonreentrant functions, since setting TZ invalidates existing
12213 tm_zone or tzname values, and since most of these functions return
12214 pointers to static storage.
12215 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12216 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12217 Grow the critical sections to include not just invoking
12218 localtime/gmtime, but also accessing these functions' results
12219 including their tm_zone values if any, and any related TZ setting.
12220 (format_time_string): Last arg is now struct tm *, not struct tm **,
12221 so that the struct tm is saved in the critical section.
12222 All callers changed. Simplify allocation of initial buffer, partly
12223 motivated by the fact that memory allocation needs to be outside
12224 the critical section.
12226 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12228 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12229 with RESET_INTERVAL.
12231 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12232 Remove duplicated buffer name initialization.
12234 2012-05-02 Jim Meyering <jim@meyering.net>
12236 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12238 * xfns.c (x_window): Use xstrdup (Bug#11375).
12240 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12242 * xdisp.c (pos_visible_p): If already at a newline from the
12243 display string before the 'while' loop, don't walk back the glyphs
12244 from it3.glyph_row. Solves assertion violation when the display
12245 string begins with a newline (egg.el). (Bug#11367)
12247 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12249 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12252 2012-05-01 Glenn Morris <rgm@gnu.org>
12254 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12255 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12256 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12257 All were removed before 23.1.
12259 * dispnew.c: Remove HAVE_LIBNCURSES test;
12260 it is always true on relevant platforms.
12262 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12263 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12265 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12267 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12269 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12270 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12273 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12275 Do not avoid creating empty evaporating overlays (Bug#9642).
12276 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12277 That is, do not delete an evaporating overlay if it becomes
12278 empty after its bounds are adjusted to fit within its buffer.
12279 This fix caused other problems, and I'm reverting it until we get
12280 to the bottom of them.
12282 2012-04-27 Chong Yidong <cyd@gnu.org>
12284 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12286 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12288 * xdisp.c (pos_visible_p): If the window start position is beyond
12289 ZV, start the display from buffer beginning. Prevents assertion
12290 violation in init_iterator when the minibuffer window is scrolled
12291 via the scroll bar.
12293 * window.c (window_scroll_pixel_based): Likewise.
12295 2012-04-27 Chong Yidong <cyd@gnu.org>
12297 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12299 2012-04-27 Glenn Morris <rgm@gnu.org>
12301 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12302 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12304 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12306 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12307 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12309 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12311 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12312 display element, check also the underlying string or buffer
12313 character. (Bug#11341)
12315 * w32menu.c: Include w32heap.h.
12316 (add_menu_item): If the call to AppendMenuW (via
12317 unicode_append_menu) fails, disable Unicode menus only if we are
12318 running on Windows 9X/Me.
12320 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12322 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12323 (xgetint): Add missing shift for LSB tags.
12325 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12327 * keyboard.c (read_char): Don't wipe echo area for select window
12328 events: These might get delayed via `mouse-autoselect-window'
12331 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12333 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12334 manipulation of :loaded-from data.
12336 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12338 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12339 now a cons (bug#11311).
12341 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12343 Do not create empty overlays with the evaporate property (Bug#9642).
12344 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12345 if it becomes empty after its bounds are adjusted to fit within
12346 its buffer. Without this fix, in a nonempty buffer (let ((o
12347 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12348 yields an empty overlay that has the evaporate property, which is
12349 not supposed to happen.
12351 Fix minor GTK3 problems found by static checking.
12352 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12353 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12354 (struct _EmacsFixedClass, emacs_fixed_get_type):
12355 Move decls here from emacsgtkfixed.h, since they needn't be public.
12356 (emacs_fixed_get_type): Now static.
12357 (emacs_fixed_class_init): Omit unused local.
12358 (emacs_fixed_child_type): Remove; unused.
12359 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12360 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12361 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12362 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12363 (EMACS_FIXED_GET_CLASS): Remove; unused.
12364 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12366 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12367 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12369 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12371 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12372 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12373 (__malloc_size_t, __malloc_ptrdiff_t):
12374 Remove. All uses removed, replaced by the definiens if needed,
12375 since we can assume C89 or better now.
12376 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
12377 (protect_malloc_state, align, get_contiguous_space)
12378 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
12379 (malloc_atfork_handler_child, malloc_enable_thread)
12380 (malloc_initialize_1, __malloc_initialize, morecore_nolock)
12381 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
12382 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
12383 (special_realloc, _realloc_internal_nolock, _realloc_internal)
12384 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12385 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12386 Define using prototypes, not old style.

12464 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12466 * sysdep.c [__FreeBSD__]: Minor cleanups.
12467 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12468 Use Emacs indenting style more consistently. Avoid some casts.

12487 * print.c (print_preprocess): Only check print_depth if print-circle
12489 (print_object): Check for cycles even when print-circle is nil and

12494 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12495 set the status to "failed" and ensure that sentinel is run.

12552 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12553 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12554 (NEED_MEM_INSERT): New macro.
12555 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12556 Remove one incorrect comment and fix another.

12592 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12593 * s/netbsd.h, s/sol2-6.h:
12594 Remove definition of GC_MARK_STACK, since the default now works.
12595 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12623 2012-04-11 Daniel Colascione <dancol@dancol.org>
12625 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12626 against is gone. It's better to use vfork now so that when Cygwin
12627 gains a new, working vfork, we use it automatically (bug#10398).
12629 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12650 being loaded (bug#10424).
12652 2012-04-09 Glenn Morris <rgm@gnu.org>
12654 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

12682 * minibuf.c (Fread_variable): Callers changed.
12684 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12686 * xdisp.c (set_cursor_from_row): If the display string appears in
12687 the buffer at position that is closer to point than the position
12688 after the display string, display the cursor on the first glyph of
12689 the display string. Fixes cursor display when a 'display' text
12690 property immediately follows invisible text. (Bug#11094)
12692 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12694 composite.c: use 'double' consistently
12695 * composite.c (get_composition_id): Use 'double' consistently
12696 instead of converting 'float' to 'double' and vice versa; this is
12697 easier to understand and avoids a GCC warning.
12699 2012-04-09 Glenn Morris <rgm@gnu.org>
12701 * Makefile.in: Generate leim-list with bootstrap-emacs, in

12746 [!WINDOWSNT]: New macros.
12747 (init_libxml2_functions, libxml2_loaded_p): New functions.

12751 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12753 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12754 Call init_libxml2_functions before calling libxml2 functions.

12763 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12765 * indent.c (Fvertical_motion): If there is a display string at
12766 point, use it.vpos to compute how many lines to backtrack after
12767 move_it_to point. (Bug#11133)
12769 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12771 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12772 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12773 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12774 macros related to unification of CJK characters. For the details,
12775 see the discussion following the message here:
12776 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

12792 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12794 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12795 position we get to after a call to move_it_to fails the
12796 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12797 only if we wind up in a string from display property. (Bug#11063)
12799 * window.c (Fdelete_other_windows_internal): Invalidate the row
12800 and column information about mouse highlight, so that redisplay
12801 restores it after reallocating the glyph matrices. (Bug#7464)
12803 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12804 string comes from a `display' text property, use the buffer
12805 position of that property as if we actually saw that position in
12807 (move_it_by_lines): Remove the assertion that
12808 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12809 violated when there's a before-string at the beginning of a line.

12818 (display_line): Call extend_face_to_end_of_line when the default
12819 face was remapped. (Bug#11068)

12831 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12834 2012-03-26 Kenichi Handa <handa@m17n.org>
12836 * dispextern.h (struct glyph): Fix previous change. Change the
12837 bit length of glyphless.ch to 25 (Bug#11082).
12839 2012-03-26 Chong Yidong <cyd@gnu.org>
12841 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12842 (command_loop_1): Use it; inhibit selection update for
12843 handle-select-window too (Bug#8996).
12845 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12847 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12849 2012-03-25 Kenichi Handa <handa@m17n.org>
12851 * dispextern.h (struct glyph): Change the bit length of
12852 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12854 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12856 * s/ms-w32.h (tzname): Include time.h before redirecting to
12857 _tzname. Fixes the MSVC build. (Bug#9960)
12859 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12861 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12864 * xterm.c (XTread_socket): Only modify handling_signal if
12865 !SYNC_INPUT. (Bug#11080)
12867 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12869 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12870 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12871 when fetching a multibyte character consumes more bytes than
12872 CHAR_BYTES returns, due to unification of CJK characters in
12873 string_char. (Bug#11073)
12875 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12877 * process.c (wait_reading_process_output): Handle pty disconnect
12878 by refraining from sending oneself a SIGCHLD (bug#10933).
12880 2012-03-22 Chong Yidong <cyd@gnu.org>

12884 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12885 Mark string as coming from a prefix property.
12886 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12887 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12889 2012-03-21 Chong Yidong <cyd@gnu.org>
12891 * xfaces.c (Vface_remapping_alist): Doc fix.
12893 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12895 * w32proc.c (Fw32_set_console_codepage)
12896 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12899 2012-03-20 Chong Yidong <cyd@gnu.org>
12901 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12902 to reflect default non-nil value of redisplay-dont-pause.
12904 2012-03-19 Kenichi Handa <handa@m17n.org>
12906 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12907 it fit in a valid range (Bug#11003).
12909 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12911 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12912 that is not from display property, accept the row as a "cursor
12913 row" if one of the string's character has a non-nil `cursor'
12914 property. Fixes cursor positioning when there are newlines in
12915 overlay strings, e.g. in icomplete.el. (Bug#11035)
12917 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12919 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12921 2012-03-12 Chong Yidong <cyd@gnu.org>
12923 * eval.c (inhibit_lisp_code): Rename from
12924 inhibit_window_configuration_change_hook; move from window.c.
12926 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12927 * window.c (run_window_configuration_change_hook)
12928 (syms_of_window): Callers changed.
12930 2012-03-11 Chong Yidong <cyd@gnu.org>
12932 * keymap.c (Fkey_description): Doc fix (Bug#9700).
12934 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12936 2012-03-10 Chong Yidong <cyd@gnu.org>
12938 * frame.c (other_visible_frames): Don't assume the selected frame
12939 is visible (Bug#10955).
12941 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12943 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12947 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12948 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12951 2012-03-03 Glenn Morris <rgm@gnu.org>
12953 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12955 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12957 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12958 position past the first glyph_row that ends at ZV. (Bug#10902)
12959 (redisplay_window, next_element_from_string): Fix typos in
12961 (redisplay_window): Pass to move_it_vertically the margin in
12962 pixels, not in screen lines.
12964 2012-03-02 Glenn Morris <rgm@gnu.org>
12966 * buffer.c (buffer-list-update-hook): Doc fix.
12968 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12970 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12971 push_it before setting up the iterator for the first overlay
12972 string, even if we have an empty string loaded.
12973 (next_overlay_string): If there's an empty string on the iterator
12974 stack, pop the stack. (Bug#10903)
12976 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12978 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12979 Suggested by Stefan Monnier in
12980 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12981 * alloc.c (widen_to_Lisp_Object): New static function.
12982 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12983 and widening them to Lisp_Objects. This would work even if
12984 USE_LSB_TAG is defined and wide integers are used, which might
12985 happen in a future version of Emacs.
12987 2012-02-25 Chong Yidong <cyd@gnu.org>
12989 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12992 * xselect.c (Fx_selection_exists_p): Doc fix.
12993 (x_clipboard_manager_save_all): Print an informative message
12994 before saving to clipboard manager.
12996 2012-02-24 Chong Yidong <cyd@gnu.org>
12998 * keyboard.c (process_special_events): Handle all X selection
12999 requests in kbd_buffer, not just the next one (Bug#8869).
13001 2012-02-23 Chong Yidong <cyd@gnu.org>
13003 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13004 call when setting menu-bar-lines and tool-bar-lines parameters.
13005 (unwind_create_frame_1): New helper function.
13007 * window.c (inhibit_window_configuration_change_hook): New var.
13008 (run_window_configuration_change_hook): Obey it.
13009 (syms_of_window): Initialize it.
13011 2012-02-22 Chong Yidong <cyd@gnu.org>
13013 * xterm.c (x_draw_image_relief): Add missing type check for
13014 Vtool_bar_button_margin (Bug#10743).
13016 2012-02-21 Chong Yidong <cyd@gnu.org>
13018 * fileio.c (Vfile_name_handler_alist): Doc fix.
13020 * buffer.c (Fget_file_buffer): Protect against invalid file
13021 handler return value.
13023 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13025 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13026 when computing $valmask.
13028 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13029 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13030 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13031 It's useless in that case, and it can cause problems on hosts
13032 that allocate halves of EMACS_INT values separately.
13033 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13034 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13035 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13036 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13037 it avoids undefined behavior on hosts where shifting right by more
13038 than the word width has undefined behavior.
13040 2012-02-19 Chong Yidong <cyd@gnu.org>
13042 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13043 (Funhandled_file_name_directory, Ffile_name_as_directory)
13044 (Fdirectory_file_name, Fexpand_file_name)
13045 (Fsubstitute_in_file_name): Protect against invalid file handler
13046 return values (Bug#10845).
13048 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13050 * .gdbinit (pitx): Fix incorrect references to fields of the

13060 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13062 2012-02-15 Chong Yidong <cyd@gnu.org>
13064 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13065 marked as special. Also, starting docstrings with * is obsolete.
13067 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13069 * gnutls.c (emacs_gnutls_write): Fix last change.

13078 * keymap.c (Fsingle_key_description): Handle char ranges.
13080 2012-02-12 Chong Yidong <cyd@gnu.org>
13082 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13083 as that creates a dangerous corner case.
13085 * window.c (Fdelete_window_internal): Invalidate the mouse
13086 highlight (Bug#9904).
13088 2012-02-12 Glenn Morris <rgm@gnu.org>

13091 (Fx_get_selection_internal, Fx_disown_selection_internal)
13092 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13093 * nsselect.m (Fx_own_selection_internal)
13094 (Fx_disown_selection_internal, Fx_selection_exists_p)
13095 (Fx_selection_owner_p, Fx_get_selection_internal):
13096 Sync docs and argument specs with the xselect.c versions.
13098 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13100 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13102 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13104 * w32select.c (Fx_selection_exists_p): Sync doc string and
13105 argument list with xselect.c. (Bug#10783)

13118 2012-02-07 Chong Yidong <cyd@gnu.org>
13120 * buffer.c (Fbuffer_local_variables)
13121 (buffer_lisp_local_variables): Handle unbound vars correctly;
13122 don't let Qunbound leak into Lisp.
13124 2012-02-07 Glenn Morris <rgm@gnu.org>
13126 * image.c (Fimagemagick_types): Doc fix.
13128 * image.c (imagemagick-render-type): Change it from a lisp object
13129 to an integer. Move the doc here from the lisp manual.
13130 Treat all values not equal to 0 the same.
13132 2012-02-06 Chong Yidong <cyd@gnu.org>
13134 * doc.c (store_function_docstring): Avoid applying docstring of
13135 alias to base function (Bug#2603).
13137 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

13142 2012-02-04 Chong Yidong <cyd@gnu.org>
13144 * nsterm.m: Declare a global (Bug#10694).
13146 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13148 * w32.c (get_emacs_configuration_options):
13149 Include --enable-checking, if specified, in the return value.
13151 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13153 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13154 after rounding frame sizes. (Bug#9723)

13158 * keyboard.c (adjust_point_for_property): Don't position point
13159 before BEGV. (Bug#10696)
13161 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13163 Handle overflow when computing char display width (Bug#9496).
13164 * character.c (char_width): Return EMACS_INT, not int.
13165 (char_width, c_string_width): Check for overflow when
13166 computing the width; this is possible now that individual
13167 characters can have unbounded width. Problem introduced
13168 by merge from Emacs 23 on 2012-01-19.
13170 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13172 * dbusbind.c (Fdbus_register_method): Mention the return value
13173 :ignore in the docstring.
13175 2012-02-02 Glenn Morris <rgm@gnu.org>
13177 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

13185 2012-02-02 Kenichi Handa <handa@m17n.org>
13187 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13188 0, do not call append_composite_glyph.
13190 2012-02-02 Kenichi Handa <handa@m17n.org>
13192 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13194 (x_produce_glyphs): If the component of a composition is a null
13195 string, set it->pixel_width to 1 to avoid zero-width glyph.
13197 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13199 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13200 first 2 arguments are identical. This makes inserting large
13201 output from a subprocess an order of magnitude faster on
13202 MS-Windows, where all sbrk'ed memory is always contiguous.
13204 2012-01-31 Glenn Morris <rgm@gnu.org>
13206 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13242 2012-01-21 Chong Yidong <cyd@gnu.org>
13244 * floatfns.c (Fcopysign): Make the second argument non-optional,
13245 since nil is not allowed anyway.
13247 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13249 * process.c (read_process_output): Use p instead of XPROCESS (proc).

13252 2012-01-19 Martin Rudalics <rudalics@gmx.at>
13254 * window.c (save_window_save, Fcurrent_window_configuration)
13255 (Vwindow_persistent_parameters): Do not use Qstate.
13256 Rewrite doc-strings.
13258 2012-01-19 Kenichi Handa <handa@m17n.org>
13260 * character.c (char_width): New function.
13261 (Fchar_width, c_string_width, lisp_string_width):
13262 Use char_width (Bug#9496).

13267 (Fset_window_configuration, save_window_save): Handle persistent
13270 2012-01-14 Eli Zaretskii <eliz@gnu.org>
13272 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
13273 thrashing the stack of the thread. (Bug#9087)
13275 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
13277 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.
13279 2012-01-11 Eli Zaretskii <eliz@gnu.org>

13282 highlight ends on a newline. (Bug#10464)
13283 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
13284 he end column for display of highlight that ends on a newline
13287 2012-01-11 Glenn Morris <rgm@gnu.org>
13289 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
13290 from load-path also when installation-directory is nil. (Bug#10208)
13292 2012-01-10 Glenn Morris <rgm@gnu.org>
13294 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
13296 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
13297 Update template values to be closer to their typical values these days.
13299 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13301 * xdisp.c (rows_from_pos_range): Accept additional argument
13302 DISP_STRING, and accept any glyph in a row whose object is that
13303 string as eligible for mouse highlight. Fixes mouse highlight of
13304 display strings from overlays. (Bug#10464)
13306 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
13308 emacs: fix an auto-save permissions race condition (Bug#10400)
13309 * fileio.c (auto_saving_dir_umask): New static var.
13310 (Fmake_directory_internal): Use it.
13311 (do_auto_save_make_dir): Set it, instead of invoking chmod after
13312 creating the directory. The old code temporarily assigns
13313 too-generous permissions to the directory.
13314 (do_auto_save_eh): Clear it.
13315 (Fdo_auto_save): Catch all errors, not just file errors, so
13316 that the var is always cleared.

13817 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13818 Otherwise, valgrind does not work on some platforms.
13819 Problem reported by Andreas Schwab in
13820 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13821 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13822 is set, removing the need for VIRT_ADDRESS_VARIES.
13823 (PURE_P): Use a more-efficient implementation that needs just one
13824 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13825 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13826 to 4 (xorl, subq, cmpq, setbe).
13827 * alloc.c (pure): Always extern now, since that's the
13828 VIRT_ADDR_VARIES behavior.
13829 (PURE_POINTER_P): Use a single comparison, not two, for
13830 consistency with the new puresize.h.
13831 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13832 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13833 Remove VIRT_ADDR_VARIES no longer needed.

13838 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13839 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13840 behave as if the cursor position were at the window margin.
13842 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13843 and the cursor position is out of bounds, behave as if the cursor
13844 position were at the window margin. (Bug#10075)
13846 2011-11-18 Chong Yidong <cyd@gnu.org>
13848 * window.c (Fwindow_combination_limit): Make first argument

13866 hash values of the two rows. (Bug#10035)
13867 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13869 * xdisp.c (row_hash): New function, body extracted from
13870 compute_line_metrics.
13871 (compute_line_metrics): Call row_hash, instead of computing the
13874 * dispnew.c (verify_row_hash): Call row_hash for computing the
13875 hash code of a row, instead of duplicating code from xdisp.c.
13877 * dispextern.h (row_hash): Add prototype.
13879 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13907 (Fsplit_window_internal, saved_window)
13908 (Fset_window_configuration, save_window_save): Rename all
13909 occurrences of window_nest to window_combination_limit.

13915 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13917 * xdisp.c (display_line): Move the call to
13918 highlight_trailing_whitespace before the call to
13919 compute_line_metrics, since the latter needs to see the final
13920 faces of all the glyphs to compute ROW's hash value.
13921 Fixes assertion violations in row_equal_p. (Bug#10035)
13923 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13925 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13926 just return (bug#10044).
13928 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13930 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13931 with user-defined heap size. Bump the default size of the temacs
13932 heap to 27MB, to avoid memory warning when running temacs.
13933 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13935 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13936 current_matrix and desired_matrix. (Bug#9990)
13937 (verify_row_hash) [XASSERTS]: New function.

13982 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13984 Avoid some portability problems by eschewing 'extern inline' functions.
13985 The trivial performance wins aren't worth the portability hassles; see
13986 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13988 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14054 * xmenu.c (cleanup_widget_value_tree): New function.
14055 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14056 calling free_menubar_widget_value_tree directly (Bug#9830).

14062 (window_box_width, window_box_left, window_box_left_offset)
14063 (window_box_right, window_box_right_offset): Declare extern.
14064 Otherwise, these inline functions do not conform to C99 and
14065 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14066 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14067 * intervals.c (adjust_intervals_for_insertion)

14070 (static_offset_intervals): Remove.
14071 (offset_intervals): Rewrite using the old contents of
14072 static_offset_intervals. The old version didn't conform to C99
14073 because an extern inline function contained a reference to an
14074 identifier with static linkage.

14240 (x_handle_net_wm_state): Return what get_current_wm_state returns.
14241 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
14243 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14245 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14246 so that this new function doesn't get optimized away by a
14247 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14249 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14251 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14253 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14255 Fix the `xbytecode' command.
14256 * .gdbinit (xprintbytestr): New command.
14257 (xwhichsymbols): Rename from `which'; all callers changed.
14258 (xbytecode): Print the byte-code string as well.
14260 2011-10-29 Kim Storm <storm@cua.dk>
14262 * alloc.c (which_symbols): New function.
14264 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14266 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14269 2011-10-29 Glenn Morris <rgm@gnu.org>
14271 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14272 Not clear what it was for, and it causes various bugs. (Bug#9839)
14274 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14276 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14277 possible random value that matches one of those tested as
14278 condition to clear the mouse face.
14280 2011-10-28 Chong Yidong <cyd@gnu.org>
14282 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14284 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14286 * window.c (make_window): Initialize phys_cursor_on_p.
14288 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14290 * lisp.h (struct Lisp_Symbol): Update comments.
14292 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14294 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14296 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14298 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14299 <oslsachem@gmail.com> for helping to debug this.
14301 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14302 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14303 (g_b_init_get_glyph_outline_w): New static variables.
14304 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14305 (GetGlyphOutlineW_Proc): New typedefs.
14306 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14307 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14309 (w32font_open_internal, compute_metrics):
14310 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14311 instead of calling the "wide" APIs directly.
14313 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14315 * w32.h (syms_of_w32font): Add prototype.
14317 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14319 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14320 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14321 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14322 (Fmove_to_window_line): Doc fix.
14324 2011-10-27 Chong Yidong <cyd@gnu.org>
14326 * process.c (make_process): Set gnutls_state to NULL.
14328 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14329 non-NULL, regardless of GNUTLS_INITSTAGE.
14330 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14331 an error. Set process slots as soon as we allocate them.
14333 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14335 2011-10-27 Chong Yidong <cyd@gnu.org>
14337 * gnutls.c (emacs_gnutls_deinit): New function.
14338 Deallocate credentials structures as well as calling gnutls_deinit.
14339 (Fgnutls_deinit, Fgnutls_boot): Use it.
14341 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14342 (deactivate_process): Call emacs_gnutls_deinit.
14344 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14346 * image.c (x_create_x_image_and_pixmap):
14347 * w32.c (sys_rename, w32_delayed_load):
14348 * w32font.c (fill_in_logfont):
14349 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14351 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14353 * w32fns.c (w32_default_color_map): New function,
14354 extracted from Fw32_default_color_map.
14355 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14357 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14359 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14361 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14363 * keyboard.c (test_undefined): New function (bug#9751).
14364 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14366 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14368 * sysdep.c (init_sys_modes): Fix the check for the controlling
14369 terminal (Bug#6649).
14371 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14373 * dispextern.h (struct bidi_it): New member next_en_type.
14375 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14376 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14377 current character, check also for next_en_type being WEAK_EN.
14378 (bidi_resolve_weak): Don't enter the expensive loop if the current
14379 position is before next_en_pos. Record the bidi type of the first
14380 non-ET, non-BN character we find, in addition to its position.
14381 (bidi_level_of_next_char): Invalidate next_en_type when
14382 next_en_pos is over-stepped.
14384 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14386 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14387 * editfns.c: Rewrite current-time-zone so that it invokes
14388 the equivalent of (format-time-string "%Z") to get the time zone name.
14389 This fixes a bug when the time zone name contains characters that
14390 need converting from the system time locale to Emacs internal format.
14391 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14392 that patch fixed format-time-string to do the conversion, but
14393 I forgot to fix current-time-zone.
14394 (format_time_string): New function, containing most of
14395 what Fformat_time_string used to contain.
14396 (Fformat_time_string): Rewrite in terms of format_time_string.
14397 This doesn't change this function's behavior.
14398 (current-time-zone): Rewrite to use format_time_string.
14399 This fixes the bug reported by Michael Schierl in
14400 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14401 Jason Rumney's 2007-06-07 change worked around this bug, but
14403 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14405 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14407 * xdisp.c (start_display): If the character at POS is displayed
14408 via a display vector, reset IT->current.dpvec_index to zero.
14409 (try_window_reusing_current_matrix): If a line ends in a display
14410 vector or the next line starts in a display vector, continue
14411 redrawing the window even though the character position of
14412 start_row was reached.
14415 2011-10-18 Chong Yidong <cyd@gnu.org>
14417 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14418 with nobreak-char-display too.
14420 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14422 Fix part 3 of bug#9771.
14423 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14424 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14425 non-neutral characters if the current character is a paragraph
14426 separator (a.k.a. Newline). This avoids running the same
14427 expensive loop twice, once when we consume the preceding newline
14428 and the other time when the line actually needs to be displayed.
14429 Avoid the loop when we see neutrals on the base embedding level
14430 following a character whose directionality is the same as the
14431 paragraph's. This avoids running the expensive loop when a line
14432 ends in a long sequence of neutrals, like control characters.
14433 Add assertion against STRONG_AL type. Slightly rearrange code
14434 that determines the type of a neutral given the first non-neutral
14436 (bidi_level_of_next_char): Set next_en_pos to zero when
14437 invalidating its info.
14439 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14441 * xdisp.c (push_display_prop): Determine whether to record string
14442 or buffer position by IT->string, not by IT->method. Allow
14443 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14444 (move_it_vertically_backward): Don't look for character position
14445 immediately after the newline when in a continuation line.
14448 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14450 * window.c (coordinates_in_window): Rewrite and delabelize
14451 vertical border check. (Bug#5357) (Bug#9618)
14453 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14455 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14456 errors in XSetWindowBorder (bug#9310).
14458 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14460 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14461 avoid crash when xmalloc overrun checking is enabled.
14463 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14465 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14466 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14467 cursor motion with <left> and <right> arrow keys.
14469 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14470 some callers set that themselves.
14472 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14474 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14475 display string and the previous row comes from the same string and
14476 is empty. (Bug#9739) (Bug#9738)
14478 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14480 * doc.c (get_doc_string): Encode file name (bug#9735).
14482 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14484 * bidi.c (bidi_level_of_next_char):
14485 * xdisp.c (get_visually_first_element): Remove old incorrect
14486 comments regarding the Unicode Line Separator character.
14488 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14490 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14492 * alloc.c (Fgc_status): Do not access beyond zombies array
14493 boundary if nzombies > MAX_ZOMBIES.
14494 * alloc.c (dump_zombies): Add missing format specifier.
14496 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14498 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14499 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14501 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14502 Some packages use them to denote characters with modifiers.
14504 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14506 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14507 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14508 matching a pp-number. Rename parameter var to var1.
14510 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14512 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14514 2011-10-08 Glenn Morris <rgm@gnu.org>
14516 * callint.c (Fcall_interactively): Give a more explicit error for the
14517 'c' case with a non-character input. (Bug#8479)
14519 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14521 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14523 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14524 lines that are hscrolled on the left.
14526 * dispnew.c (buffer_posn_from_coords): Account for a possible
14527 presence of header-line. (Bug#4426)
14529 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14531 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14532 Don't advertise functionality which we discourage or doesn't work.
14534 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14536 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14537 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14538 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14539 this makes Emacs dump core during garbage collection on rare
14540 occasions. sizeof is obviously inferior to offsetof here, so
14541 stick with offsetof.
14542 (GC_POINTER_ALIGNMENT): New macro.
14543 (mark_memory): Omit 3rd (offset) arg; caller changed.
14544 Don't assume EMACS_INT alignment is the same as pointer alignment.
14546 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14548 * keyboard.c (read_key_sequence_remapped): New var.
14549 (read_key_sequence): Compute remapping in the right buffer.
14550 (command_loop_1): Use read_key_sequence's remapping directly.
14552 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14554 * dired.c (file_name_completion): Don't expand file name.
14555 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14556 before checking file name handler.
14558 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14559 they've been requested explicitly (bug#9591).
14561 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14563 * keymap.c (Fsingle_key_description): Use make_specified_string
14564 instead of build_string to build string from push_key_description.
14567 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14569 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14570 This fixes a Y2038 bug on 64-bit hosts.
14571 * buffer.c (reset_buffer):
14572 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14573 (Fclear_buffer_auto_save_failure):
14574 Use 0, not -1, to represent an unset failure time, since time_t
14575 might not be signed.
14577 Remove dependency on glibc malloc internals.
14578 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14579 Move back here from lisp.h, but with their new implementations.
14580 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14581 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14582 * charset.c (charset_table_init): New static var.
14583 (syms_of_charset): Use it instead of xmalloc. This removes a
14584 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14585 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14586 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14587 Move back to alloc.c.
14588 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14589 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14591 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14593 * nsterm.m (windowDidResize): Call x_set_window_size only when
14594 ns_in_resize is true. Otherwise set pixelwidth/height and
14595 call change_frame_size (Bug#9628).
14597 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14599 Port --enable-checking=all to Fedora 14 x86-64.
14600 * charset.c (syms_of_charset): Also account for glibc malloc's
14601 internal overhead when calculating the initial malloc maximum.
14603 Port --enable-checking=all to Fedora 14 x86.
14604 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14606 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14607 (overrun_check_realloc, overrun_check_free):
14608 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14609 That way, xmalloc returns a properly-aligned pointer even if
14610 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14611 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14612 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14613 into account when calculating the initial malloc maximum.
14614 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14615 Move here from alloc.c, so that charset.c can use it too.
14616 Properly align; the old code wasn't right for common 32-bit hosts
14617 when configured with --enable-checking=all.
14618 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14619 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14621 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14623 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14626 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14628 * xdisp.c (compute_display_string_end): If there's no display
14629 string at CHARPOS, return -1.
14631 * bidi.c (bidi_fetch_char): When compute_display_string_end
14632 returns a negative value, treat the character as a normal
14633 character not covered by a display string. (Bug#9624)
14635 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14637 * lread.c (Fread_from_string): Fix typo in docstring.
14639 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14641 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14642 newline, reseat the iterator instead of bidi-iterating there one
14643 character at a time. (Bug#9610)
14644 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14645 TO_CHARPOS if the bidi iterator is at base embedding level.
14647 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14649 * lread.c (readevalloop): Use correct code for NBSP.
14650 (read1): Likewise. (Bug#9608)
14652 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14654 * dbusbind.c (Fdbus_register_signal): When service is not
14655 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14657 2011-09-25 Glenn Morris <rgm@gnu.org>
14659 * buffer.c (truncate-lines): Doc fix.
14661 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14663 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14664 (Fset_window_next_buffers): Doc fix.
14666 2011-09-24 Glenn Morris <rgm@gnu.org>
14668 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14670 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14672 Fix minor problems found by static checking.
14673 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14674 * indent.c (Fvertical_motion): Fix == vs = typo.
14676 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14678 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14679 Default value is now t. Doc fix.
14681 * indent.c (Fvertical_motion): Compute and apply the overshoot
14682 logic when moving up, not only when moving down. Fix the
14683 confusing name and values of the it_overshoot_expected variable;
14684 logic changes accordingly. (Bug#9254) (Bug#9549)
14686 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14687 CHARPOS is covered by a display string which includes newlines.
14688 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14689 is covered by a display string with embedded newlines.
14691 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14693 * dbusbind.c (Fdbus_register_signal): Add match rule to
14694 Vdbus_registered_objects_table. (Bug#9581)
14695 (Fdbus_register_method, Vdbus_registered_objects_table):
14698 2011-09-24 Jim Meyering <meyering@redhat.com>
14700 do not ignore write error for any output size
14701 The previous change was incomplete.
14702 While it makes emacs --batch detect the vast majority of stdout
14703 write failures, errors were still ignored whenever the output size is
14704 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14705 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14706 && echo FAIL: ignored write error
14707 FAIL: ignored write error
14708 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14709 && echo FAIL: ignored write error
14710 FAIL: ignored write error
14711 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14713 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14715 * emacs.c (Fkill_emacs): In noninteractive mode exit
14716 non-successfully if a write error occurred on stdout. (Bug#9574)
14718 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14720 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14723 * dispextern.h (struct it): Update the comment documenting what
14726 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14728 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14729 a display string, extend search for cursor position to end of row.
14730 (find_row_edges): If the row ends in a newline from a display
14731 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14732 Handle the case of a display string with multiple newlines.
14733 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14734 non-empty line. Fixes confusing cursor motion with arrow keys at
14735 the beginning of a line that starts with whitespace.
14737 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14739 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14742 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14744 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14745 boolean (Bug#9154).
14747 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14749 * xdisp.c (display_line): Record maximum and minimum buffer
14750 positions even if no glyphs were produced (e.g., by a zero-width
14751 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14752 buffer positions that will be removed from the glyph row because
14754 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14755 column is beyond frame width: don't subtract 1 "pixel" when
14756 computing width of the stretch.
14757 (reseat_at_next_visible_line_start): Undo the change made on
14758 2011-09-17 that saved paragraph information and restored it after
14759 the call to `reseat'. (Bug#9545)
14761 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14763 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14764 and turn window cursor on if cleared (Bug#9415).
14766 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14768 * search.c (boyer_moore): Take unibyte characters from pattern
14769 literally. (Bug#9458)
14771 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14773 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14775 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14777 Fix minor problem found by static checking.
14778 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14779 initialized, to pacify gcc -Wuninitialized.
14781 * fileio.c: Report proper errno when syscall falls.
14782 (Finsert_file_contents): Save and restore errno,
14783 so that report_file_error outputs the correct diagnostic.
14784 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14786 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14788 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14790 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14792 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14793 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14795 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14797 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14798 about the current paragraph and restore it after the call to reseat.
14800 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14801 (bidi_find_paragraph_start): Search back for paragraph beginning
14802 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14803 (bidi_move_to_visually_next): Only trigger paragraph-related
14804 computations when the last character is a newline or at EOB, not
14805 just any NEUTRAL_B. (Bug#9470)
14807 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14808 truncated lines if point is covered by a display string. (Bug#9524)
14810 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14812 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14813 (cons_to_x_long): New function.
14814 (lisp_data_to_selection_data): Use it. Correct the test for
14815 short-versus-long data; it was negated. Break out of vector
14816 loop, for efficiency, when a long datum is discovered.
14818 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14820 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14822 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14824 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14825 GCC PR/17406) by declaring this function with external scope.
14827 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14829 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14830 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14832 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14834 * editfns.c (Fformat): Correctly handle text properties on "%%".

14840 * term.c (encode_terminal_code):
14841 * composite.c (composition_update_it, get_composition_id):
14842 * xdisp.c (get_next_display_element)
14843 (fill_composite_glyph_string): Add comments about special meaning
14844 of TAB characters in a composition.
14846 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14848 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14849 This occurs when processing a multibyte format.
14850 Problem reported by Wolfgang Jenker.
14852 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14854 * xdisp.c (try_cursor_movement): Only check for exact match if
14855 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14857 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14859 Remove unused external symbols.
14860 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14861 * xdisp.c (calc_pixel_width_or_height): Now static.
14862 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14863 * indent.c (check_display_width):
14864 * w32term.c: Fix comment to match code.
14865 * xterm.c, xterm.h (x_catching_errors): Remove.
14867 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14869 * xselect.c: Use signed conversions more consistently (Bug#9498).
14870 (selection_data_to_lisp_data): Assume incoming selection data are
14871 signed integers, not unsigned. This is to be consistent with
14872 outgoing selection data, which was modified to use signed integers
14873 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14874 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14875 expects long, not unsigned long.
14877 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14879 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14880 computation of loop end. Reported by Johan Bockgård
14883 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14885 * frame.c (Fother_visible_frames_p): Function deleted.
14887 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14889 * indent.c (compute_motion): Process display vector front to back
14890 rather than the other way around. (Bug#2496)
14892 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14894 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14896 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14898 * minibuf.c (Fread_from_minibuffer): Doc fix.
14900 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14902 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14903 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14905 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14907 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14908 value for non-existent files.
14910 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14912 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14913 set its "size" to -1. This will set the modtime_size field of
14914 the corresponding buffer to -1, which is what
14915 verify-visited-file-modtime expects for files that do not exist.
14918 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14920 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14922 * lisp.h: ... from here. push_key_description is no longer
14923 defined in keyboard.c, so its declaration should not be in
14924 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14925 logically belongs with push_key_description.
14927 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14929 * buffer.h: Include <sys/types.h> instead of <time.h>.
14930 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14931 Problem reported by Herbert J. Skuhra.
14933 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14935 * xml.c (parse_region): Make the parsing work for
14936 non-comment-starting XML files again (bug#9144).
14938 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14940 * image.c (gif_load): Fix calculation of bottom and right corner.
14943 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14945 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14946 redisplay in small windows.
14948 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14950 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14952 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14954 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14955 Operate on live windows only.
14957 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14959 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14961 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14963 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14964 only under bidi iteration.
14966 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14968 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14970 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14972 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14973 Without this fix, the command to link temacs failed due to an
14974 undefined symbol __builtin_isnan. This is because
14975 /usr/include/iso/math_c99.h #defines isnan(x) to
14976 __builtin_isnan(x), but the bundled gcc, which identifies itself
14977 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14979 * floatfns.c (isnan): #undef, and then #define to a clone of
14981 (Fisnan): Always define, since it's always available now.
14982 (syms_of_floatfns): Always define isnan at the Lisp level.
14984 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14986 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14988 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14990 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14991 The previous code assumed that file offsets (off_t values) fit in
14992 EMACS_INT variables, which is not true on typical 32-bit hosts.
14993 The code messed up by falsely reporting buffer overflow in cases
14994 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14995 when "big" contains more than 2**29 bytes, even though this
14996 inserts just one byte and does not overflow the buffer.
14997 (Finsert_file_contents): Store file offsets as off_t
14998 values, not as EMACS_INT values. Check for overflow when
14999 converting between EMACS_INT and off_t. When checking for
15000 buffer overflow or for overlap, take the offsets into account.
15001 Don't use EMACS_INT for small values where int suffices.
15002 When checking for overlap, fix a typo: ZV was used where
15003 ZV_BYTE was intended.
15004 (Fwrite_region): Don't assume off_t fits into 'long'.
15005 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15007 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15009 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15011 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15013 sprintf-related integer and memory overflow issues (Bug#9412).
15015 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15016 (esprintf, exprintf, evxprintf): New functions.
15017 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15018 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15019 (modify_event_symbol): Do not assume that the length of
15020 name_alist_or_stem is safe to alloca and fits in int.
15021 (Fexecute_extended_command): Likewise for function name and binding.
15022 (Frecursion_depth): Wrap around reliably on integer overflow.
15023 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15024 since some callers pass EMACS_INT values.
15025 (Fsingle_key_description): Don't crash if symbol name contains more
15026 than MAX_ALLOCA bytes.
15027 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15028 (get_minibuffer): Arg is now EMACS_INT, not int.
15029 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15030 (esprintf, exprintf, evxprintf): New decls.
15031 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15033 * dbusbind.c (signature_cat): New function.
15034 (xd_signature, Fdbus_register_signal):
15035 Do not overrun buffer; instead, report string overflow.
15037 * dispnew.c (add_window_display_history): Don't overrun buffer.
15038 Truncate instead; this is OK since it's just a log.
15040 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15041 even if the time zone offset is outlandishly large.
15042 Don't mishandle offset == INT_MIN.
15044 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15045 when creating daemon; the previous buffer-overflow check was incorrect.
15047 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15048 which has the guts of the old verror function.
15050 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15051 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15053 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15054 (font_unparse_xlfd): Don't blindly alloca long strings.
15055 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15056 fits in int, when using sprintf. Use single snprintf to count
15057 length of string rather than counting it via multiple sprintfs;
15058 that's simpler and more reliable.
15059 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15060 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15061 sprintf, in case result does not fit in int.
15063 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15064 (fontset_from_font): Print it.
15066 * frame.c (tty_frame_count): Now printmax_t, not int.
15067 (make_terminal_frame, set_term_frame_name): Print it.
15068 (x_report_frame_params): In X, window IDs are unsigned long,
15069 not signed long, so print them as unsigned.
15070 (validate_x_resource_name): Check for implausibly long names,
15071 and don't assume name length fits in 'int'.
15072 (x_get_resource_string): Don't blindly alloca invocation name;
15073 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15076 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15077 (xg_check_special_colors, xg_set_geometry):
15078 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15080 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15081 Use esprintf, not sprintf, in case result does not fit in int.
15083 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15084 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15085 it as a large positive number.
15086 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15087 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15089 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15090 in case result does not fit in int.
15092 * print.c (float_to_string): Detect width overflow more reliably.
15093 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15094 buffer overrun. Don't assume list length fits in 'int'. Treat
15095 print length of 0 as 0, not as infinity; to be consistent with other
15096 uses of print length in this function. Don't overflow print length
15097 index. Don't assume hash table size fits in 'long', or that
15098 vectorlike size fits in 'unsigned long'.
15100 * process.c (make_process): Use printmax_t, not int, to format
15101 process-name gensyms.
15103 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15105 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15106 to avoid potential buffer overrun.
15108 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15109 if X resource line is longer than 512 bytes.
15111 * xfns.c (x_window): Make sprintf buffer a bit bigger
15112 to avoid potential buffer overrun.
15114 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15116 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15118 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15120 Integer overflow fixes for scrolling, etc.
15121 Without these, Emacs silently mishandles large integers sometimes.
15122 For example, "C-u 4294967297 M-x recenter" was treated as if
15123 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15125 * xdisp.c (try_window_id): Check Emacs fixnum range before
15126 converting to 'int'.
15128 * window.c (window_scroll_line_based, Frecenter):
15129 Check that an Emacs fixnum is in range before assigning it to 'int'.
15130 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15131 values converted from Emacs fixnums.
15132 (Frecenter): Don't wrap around a line count if it is out of 'int'
15133 range; instead, treat it as an extreme value.
15134 (Fset_window_configuration, compare_window_configurations):
15135 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15137 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15138 that can exceed INT_MAX. Check that EMACS_INT value is in range
15139 before assigning it to the (possibly-narrower) index.
15140 (match_limit): Don't assume that a fixnum can fit in 'int'.
15142 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15145 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15146 (Fvertical_motion): Don't wrap around LINES values that don't fit
15147 in 'int'. Instead, treat them as extreme values. This is good
15148 enough for windows, which can't have more than INT_MAX lines anyway.
15150 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15152 * Require libxml/parser.h to avoid compilation warning.
15154 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15156 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15157 since this reportedly can destroy thread storage.
15159 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15161 * syntax.c (find_defun_start): Update all cache variables if
15162 exiting early (Bug#9401).
15164 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15166 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15168 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15169 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15170 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15172 * term.c (tty_append_glyph): New function.
15173 (produce_stretch_glyph): Static function and its prototype deleted.
15175 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15178 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15180 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15181 when checking :margin (Bug#9390).
15182 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15183 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15184 so that the name doesn't mislead. All uses changed.
15186 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15188 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

15196 the first character in the line after the newline.
15198 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15200 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15201 (ccl_driver): Do not generate an out-of-range pointer.
15202 (Fccl_execute_on_string): Remove unnecessary check for
15203 integer overflow, noted by Stefan Monnier in
15204 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15205 Remove a FIXME that didn't need fixing.
15206 Simplify the newly-introduced buffer reallocation code.
15208 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15210 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15212 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15214 Integer and memory overflow issues (Bug#9196).
15216 * doc.c (get_doc_string): Rework so that
15217 get_doc_string_buffer_size is the actual buffer size, rather than
15218 being 1 less than the actual buffer size; this makes xpalloc more
15221 * image.c (x_allocate_bitmap_record, cache_image):
15222 * xselect.c (Fx_register_dnd_atom):
15223 Simplify previous changes by using xpalloc.
15225 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15226 since either will do and ptrdiff_t is convenient with xpalloc.
15228 * charset.c (charset_table_size)
15229 (struct charset_sort_data.priority): Now ptrdiff_t.
15230 (charset_compare): Don't overflow if priorities differ greatly.
15231 (Fsort_charsets): Don't assume list length fits in int.
15232 Check for size-calculation overflow when allocating sort data.
15233 (syms_of_charset): Allocate an initial charset table that is
15234 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15236 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15238 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15239 The actual value is always <= INT_MAX, and leaving it unsigned made
15240 overflow checking harder.
15242 * dispextern.h (struct glyph_matrix.rows_allocated)
15243 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15244 with xpalloc. The values are still always <= INT_MAX.
15246 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15248 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15249 (SAFE_NALLOCA): New macro.
15251 * region-cache.c (struct boundary.pos, find_cache_boundary)
15252 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15253 (set_cache_region, invalidate_region_cache)
15254 (revalidate_region_cache, know_region_cache, region_cache_forward)
15255 (region_cache_backward, pp_cache):
15256 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15257 so that ptrdiff_t * can be passed to xpalloc.
15258 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15259 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15260 (pp_cache): Don't assume cache_len fits in int.
15261 * region-cache.h: Adjust extern decls to match.
15263 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15264 EMACS_INT, since either will do, for xpalloc.
15266 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15267 (xnmalloc, xnrealloc, xpalloc): New functions.
15269 * bidi.c (bidi_shelve_header_size): New constant.
15270 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15271 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15273 * bidi.c (bidi_cache_shrink):
15274 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15276 Don't update size of array until after memory allocation succeeds,
15277 because xmalloc/xrealloc may not return.
15278 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15279 now that we have proper integer overflow checking.
15280 (record_overlay_string, overlay_strings): Catch overflows when
15281 calculating size of overlay_str_buf.
15283 * callproc.c (Fcall_process): Check for size overflow when
15284 calculating size of args2.
15285 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15286 Normally we prefer signed values, but sticking with ptrdiff_t would
15287 require adding more-complicated checks.
15289 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15290 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15291 Redo buffer-overflow calculations to avoid integer overflow.
15292 Add a FIXME comment where memory seems to be over-allocated.
15294 * character.c (Fstring): Check for size-calculation overflow.
15296 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15297 unnecessary integer overflow. Check for size overflow.
15298 (encode_coding_object): Don't update size until xmalloc succeeds.
15300 * composite.c (get_composition_id): Check for overflow in glyph
15301 length calculations.
15303 Integer and memory overflow fixes for display code.
15304 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15305 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15306 (scrolling_window): Check for overflow in size calculations.

15318 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15319 (get_doc_string): Check for size calculation overflow.
15320 Don't update size until allocation succeeds.
15321 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15322 EMACS_INT, where ptrdiff_t will do.
15323 (Fsubstitute_command_keys): Check for string overflow.
15325 * editfns.c (set_time_zone_rule): Don't assume environment length
15327 (message_length): Now ptrdiff_t, not int.
15328 (Fmessage_box): Don't update size until allocation succeeds.
15329 Don't assume message length fits in int.
15330 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15332 * emacs.c (main): Do not reallocate argv, since there is a null at
15333 the end that can be overwritten, and this way there's no need to
15334 worry about size-calculation overflow.
15335 (sort_args): Check for size-calculation overflow.
15337 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15339 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15341 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15342 (x_set_scroll_bar_width, x_figure_window_size):
15343 Check for integer overflow.
15344 (x_set_alpha): Do not assume XINT fits in int.
15346 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15347 This is for the members text_lines, text_cols, total_lines, total_cols,
15348 where the system imposes an 'int' limit.
15350 * fringe.c (Fdefine_fringe_bitmap):
15351 Don't update size until alloc works.
15353 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15354 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15356 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15357 Check for size-calculation overflow.
15358 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15359 do, as we prefer signed integers.
15360 (id_to_widget.max_size, id_to_widget.used)
15361 (xg_store_widget_in_map, xg_remove_widget_from_map)
15362 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15363 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15364 Use and return ptrdiff_t, not int.
15365 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15366 * gtkutil.h: Change prototypes to match the above.
15368 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15369 are duplicate now that they've been promoted to lisp.h.
15370 (x_allocate_bitmap_record, x_alloc_image_color)
15371 (make_image_cache, cache_image, xpm_load):
15372 Don't update size until alloc is done.

15383 Use ptrdiff_t, not int, to count maps.
15384 (read_char_minibuf_menu_prompt): Check for overflow in size
15385 calculations. Don't update size until allocation succeeds.
15386 Redo calculations to avoid overflow.
15387 * keyboard.h: Change prototypes to match the above.

15415 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15416 for command line length. Do not attempt to address one before the
15417 beginning of an array, as that's not portable.
15419 * term.c (max_frame_lines): Remove; unused.
15420 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15422 (encode_terminal_code, calculate_costs): Check for size

15429 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15430 subtracting pointers.

15452 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15453 sizes, since they can exceed INT_MAX in size. Check for size

15457 (xg_select): Check for size calculation overflow.
15458 Don't update size until alloc done.
15460 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15461 as sprintf is limited to int lengths.
15463 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15464 (X_LONG_MIN): New macros.
15465 Use them to make the following changes clearer.
15466 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15467 This change doesn't affect the value now, but it may help remind
15468 future maintainers not to raise the value too much later.
15469 (SELECTION_QUANTUM): Remove, replacing with ...
15470 (selection_quantum): ... new function, which avoids overflow.
15472 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15473 assumption that selection length fits in 'int'.

15486 (lisp_data_to_selection_data, x_property_data_to_lisp):

15490 Don't store size until memory allocation succeeds.
15491 (x_get_window_property): Plug memory leak on memory exhaustion.
15492 Don't double-block input; malloc is safe here. Don't assume 2**34
15493 - 4 fits in unsigned long. Add an xassert to check
15494 XGetWindowProperty overflow. Be more careful about overflow
15495 calculations, and distinguish size from memory overflow better.

15497 unsigned int is less than INT_MAX.
15498 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15499 harmful) conversions of unsigned short to int.
15500 (lisp_data_to_selection_data): Don't assume that integers
15501 in the range -65535 through -1 fit in an X unsigned short.
15502 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15503 result parameters unless successful. Rely on cons_to_unsigned
15504 to report problems with elements; the old code wasn't right anyway.
15505 (x_check_property_data): Check for int overflow; we cannot use
15506 a wider type due to X limits.
15507 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

15539 * lisp.h (hash_lookup, hash_put):
15540 * minibuf.c (Ftest_completion):
15541 Use ptrdiff_t for hash table indexes, not int (which is too
15542 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15543 32-bit --with-wide-int hosts).
15545 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15546 Add a FIXME comment about memory leaks.
15547 (syms_of_charset): Don't assume xmalloc returns.

15554 with outlandish widths.
15555 * character.h (sanitize_tab_width): Rename from sanitize_width,
15556 now that we have two such functions. All uses changed.

15577 exceed limits imposed by XClientMessageEvent, as well as the usual
15578 ptrdiff_t and size_t limits.
15580 * keyboard.c: Overflow, signedness and related fixes.

15584 Change bufsize argument back to int, undoing my 2011-03-30 change.
15585 We prefer signed types, and int is wide enough here.
15586 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15587 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15588 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15589 length, not size_t. Use ptrdiff_t for index, not int.
15590 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15591 possibility of integer overflow.
15593 Overflow, signedness and related fixes for images.
15595 * dispextern.h (struct it.stack[0].u.image.image_id)
15596 (struct_it.image_id, struct image.id, struct image_cache.size)
15597 (struct image_cache.used, struct image_cache.ref_count):
15598 * gtkutil.c (update_frame_tool_bar):
15599 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
15600 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
15601 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
15602 * nsmenu.m (update_frame_tool_bar):
15603 * xdisp.c (calc_pixel_width_or_height):
15604 * xfns.c (image_cache_refcount):
15605 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
15606 on typical 64-bit hosts.
15608 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15609 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

15612 when the callers expect that.
15613 (image_ascent): Redo ascent calculation to avoid int overflow.
15614 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15615 (lookup_image): Remove unnecessary tests.
15616 (xbm_image_p): Locals are now of int, not EMACS_INT,
15617 since parse_image_check makes sure they fit into int.
15618 (png_load, gif_load, svg_load_image):
15619 Prefer int to unsigned where either will do.
15620 (tiff_handler): New function, combining the cores of the
15621 old tiff_error_handler and tiff_warning_handler.
15622 This function is rewritten to use vsnprintf and thereby avoid
15623 stack buffer overflows. It uses only the features of vsnprintf
15624 that are common to both POSIX and native Microsoft.
15625 (tiff_error_handler, tiff_warning_handler): Use it.
15626 (tiff_load, gif_load, imagemagick_load_image):
15627 Don't assume :index value fits in 'int'.
15628 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15629 (imagemagick_load_image): Check that crop parameters fit into
15630 the integer types that MagickCropImage accepts. Don't assume
15631 Vimagemagick_render_type has a nonnegative value. Don't assume
15632 size_t fits in 'long'.
15633 (gs_load): Use printmax_t to print the widest integers possible.
15634 Check for integer overflow when computing image height and width.
15636 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15638 * xdisp.c (redisplay_window): Don't force window start if point

15646 handle_single_display_spec, not just 1 or zero.
15647 (handle_single_display_spec): If the display spec is of the form
15648 `(space ...)', and specifies display in the text area, return 2
15650 (try_cursor_movement): Check for the need to scroll more
15651 accurately, and prefer exact match for point under bidi.
15652 Don't advance `row' beyond the last row of the window.
15654 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15655 into disp_prop; all users changed.
15657 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15658 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15659 for the text covered by the display property.

15669 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15670 buffers, return left-to-right.
15671 (set_cursor_from_row): Consider candidate row a win if its glyph
15672 represents a newline and point is on that newline. Fixes cursor
15673 positioning on the newline at EOL of R2L text within L2R
15674 paragraph, and vice versa.
15675 (try_cursor_movement): Check continued rows, in addition to
15676 continuation rows. Fixes unwarranted scroll when point enters a
15677 continued line of R2L text within an L2R paragraph, or vice versa.
15678 (cursor_row_p): Consider the case of point being equal to
15679 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15680 from the end of a short line to the beginning of a continued line
15681 of R2L text within L2R paragraph.
15682 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15683 composed characters.
15685 * bidi.c (bidi_check_type): Use xassert.
15686 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
15689 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15691 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
15694 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
15696 * nsfont.m (ns_otf_to_script): Fix typo.
15698 2011-08-22 Kenichi Handa <handa@m17n.org>
15700 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15701 extra slot even if the purpose is char-code-property-table.
15703 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15705 * xdisp.c (redisplay_window): When computing centering_position,
15706 account for the height of the header line. (Bug#8874)
15708 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15709 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15710 candidate is selected by the mouse, and that candidate has a
15711 composed character under the mouse.
15713 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15714 coordinates reported by pos-visible-in-window-p for a composed
15715 character in column zero.
15717 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15719 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15721 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15723 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15724 consider it a hit if to_charpos is anywhere in the range of the
15725 composed buffer positions.
15727 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15729 * image.c (gif_load): Don't assume that each subimage has the same
15730 dimensions as the base image. Handle disposal method that is
15731 "undefined" by the gif spec (Bug#9335).
15733 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15735 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15736 (Fcondition_case): Document `debug' symbol in error handler.
15738 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15740 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15741 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15742 from an Org mode buffer to a Speedbar frame.
15744 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15745 a composition, take its buffer position from IT->cmp_it.charpos.
15746 Fixes cursor positioning at the beginning of a line that begins
15747 with a composed character.
15749 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15751 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15752 character bidirectional type, use STRONG_L instead. Fixes crashes
15753 in a buffer produced by `describe-categories'.
15755 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15756 members before the level stack, so they would be saved and
15757 restored when copying iterator state. Fixes incorrect reordering
15758 around TABs covered by display properties.
15760 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15762 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15768 Remove unnecessary aborts (Bug#9081).
15770 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15772 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15773 has no `load' handler, try opening the file locally. (Bug#9311)
15775 2011-08-16 Ken Brown <kbrown@cornell.edu>
15777 * gmalloc.c: Expand comment.
15779 2011-08-16 Eli Zaretskii <eliz@gnu.org>

15832 * xdisp.c (move_it_in_display_line_to): Don't invoke
15833 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15834 ppos_it. Fixes vertical cursor motion when line beginning is
15835 covered by an image. (Bug#9296)
15837 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15839 * nsterm.h (ns_run_ascript): Declare.

15843 (ns_run_ascript): New function.
15844 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15845 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15846 the event loop. Get status from as_status (Bug#7276).
15848 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15849 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15850 the event loop (Bug#7276).
15852 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15876 (Fnetwork_interface_list): Allocate in increments of bytes instead
15877 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15878 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15880 (struct ifflag_def): notrailers is smart on OSX.
15881 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15882 Get hardware address with getifaddrs if available.
15884 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15886 * xdisp.c (iterate_out_of_display_property): xassert that
15887 IT->position is set to within IT->object's boundaries. Break from
15888 the loop as soon as EOB is reached; avoids infloops in redisplay

15890 Set IT->current to match the bidi iterator unconditionally.
15891 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15892 entry. Force push_it to save on the stack the current
15893 buffer/string position, to be restored by pop_it. Fix flags in
15894 the iterator structure wrt the object coming from a display
15895 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15896 properties. (Bug#9284)
15898 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15900 * fontset.c (fontset_get_font_group): Add proper type checks.

15913 no-display-properties-and-no-overlays under bidi display.
15914 Set disp_pos in the bidi iterator to avoid searches for display
15915 properties and overlays.
15917 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15919 * editfns.c (Fset_time_zone_rule): Document relationship with the

15928 restore_point_unwind (Bug#5984).
15930 2011-08-07 Juri Linkov <juri@jurta.org>
15932 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15933 to show the arg `TIME' instead of `TIMEVAL'.

15937 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15938 display property strides EOL and includes a newline, as in
15939 longlines-mode. (Bug#9254)
15940 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15941 word-wrap under bidirectional display. (Bug#9224)
15943 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15944 is non-zero, even if the data buffer is NULL. Fixes a crash in
15945 vertical-motion with longlines-mode. (Bug#9254)
15947 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15949 * bidi.c <bidi_cache_total_alloc>: Now static.

15955 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15956 amount allocated this far in `bidi_cache_total_alloc'.
15957 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15958 non-zero, only free the data buffer without restoring the cache
15959 contents. All callers changed.
15961 * dispextern.h (bidi_unshelve_cache): Update prototype.
15963 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

15970 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15972 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

16024 DISP_PROP_P, and pass it to compute_display_string_pos.
16025 Only handle text covered by a display string if DISP_PROP_P is returned
16026 non-zero. All callers of bidi_fetch_char changed.

16045 * xdisp.c (forward_to_next_line_start): Accept additional argument
16046 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16048 (reseat_at_next_visible_line_start): Use the bidi iterator state
16049 returned by forward_to_next_line_start to restore the state of
16050 it->bidi_it after backing up to previous newline. (Bug#9212)
16052 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16054 * regex.c (re_comp): Protoize.
16055 (re_exec): Fix return type.
16056 (regexec): Fix type of `ret'. (Bug#9203)
16058 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16060 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16061 This is needed if max-image-size is a floating-point number.
16063 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16065 * print.c (print_object): Print empty symbol as ##.
16067 * lread.c (read1): Read ## as empty symbol.
16069 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16071 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16072 setting frame foreground color (Bug#9175).
16073 (x_set_background_color): Likewise.
16075 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16076 contents (Bug#9176).
16077 (EmacsTooltip -init): Remove bezels and add shadows to
16080 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16081 or scroll bar (Bug#8470).
16083 * nsfont.m (nsfont_open): Remove assignment to voffset and
16084 unnecessary vars hshink, expand, hd, full_height, min_height.
16085 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16087 * nsterm.h (nsfont_info): Remove voffset field.
16089 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16091 Implement strike-through and overline on NextStep (Bug#8863).
16093 * nsfont.m (nsfont_open): Use underline position provided by font,
16094 instead of hard-coded value of 2.
16095 (nsfont_draw): Call ns_draw_text_decoration instead.
16097 * nsterm.h: Add declaration for ns_draw_text_decoration.
16099 * nsterm.m (ns_draw_text_decoration): New function for drawing
16100 underline, overline, and strike-through.
16101 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16102 ns_draw_text_decoration. Change treatment of cursor drawing to
16103 accommodate underlining, etc.
16105 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16107 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16110 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16112 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16113 Without this fix, if a signal arrives just after memory fills up,
16114 'malloc' might be invoked reentrantly.
16116 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16117 In other words, assume that every image size is allowed, on non-X
16118 hosts. This assumption is probably wrong, but it lets Emacs compile.
16120 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16122 * regex.c (re_iswctype): Convert return values to boolean.
16124 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16126 * xdisp.c (compute_display_string_pos): Don't use cached display
16127 string position if the buffer had its restriction changed.
16130 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16132 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16134 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16136 Integer signedness and overflow and related fixes. (Bug#9079)
16138 * bidi.c: Integer size and overflow fixes.
16139 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16140 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16141 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16142 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16143 (bidi_find_other_level_edge):
16144 Use ptrdiff_t instead of EMACS_INT where either will do.
16145 This works better on 32-bit hosts configured --with-wide-int.
16146 (bidi_cache_ensure_space): Check for size-calculation overflow.
16147 Use % rather than repeated addition, for better worst-case speed.
16148 Don't set bidi_cache_size until after xrealloc returns, because it
16150 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16151 (bidi_cache_ensure_space): Also check that the bidi cache size
16152 does not exceed that of the largest Lisp string or buffer. See Eli
16153 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16155 * alloc.c (__malloc_size_t): Remove.
16156 All uses replaced by size_t. See Andreas Schwab's note
16157 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16159 * image.c: Improve checking for integer overflow.
16160 (check_image_size): Assume that f is nonnull, since
16161 it is always nonnull in practice. This is one less thing to
16162 worry about when checking for integer overflow later.
16163 (x_check_image_size): New function, which checks for integer
16164 overflow issues inside X.
16165 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16166 This removes the need for a memory_full check.
16167 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16168 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16169 (xbm_read_bitmap_data): Change locals back to 'int', since
16170 their values must fit in 'int'.
16171 (xpm_load_image, png_load, tiff_load):
16172 Invoke x_create_x_image_and_pixmap earlier,
16173 to avoid much needless work if the image is too large.
16174 (tiff_load): Treat overly large images as if
16175 x_create_x_image_and_pixmap failed, not as malloc failures.
16176 (gs_load): Use x_check_image_size.
16178 * gtkutil.c: Omit integer casts.
16179 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16180 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16182 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16184 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16185 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16186 would wrongly return t on a 64-bit host.
16188 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16189 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16190 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16191 and therefore cause GCC to emit a bogus diagnostic in some cases.
16193 * image.c: Integer signedness and overflow and related fixes.
16194 This is not an exhaustive set of fixes, but it's time to
16195 record what I've got.
16196 (lookup_pixel_color, check_image_size): Remove redundant decls.
16197 (check_image_size): Don't assume that arbitrary EMACS_INT values
16198 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16199 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16200 (tiff_load, imagemagick_load_image):
16201 Check for overflow in size calculations.
16202 (x_create_x_image_and_pixmap): Remove unnecessary test for
16203 xmalloc returning NULL; that can't happen.
16204 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16205 (xpm_color_bucket): Use better integer hashing function.
16206 (xpm_cache_color): Don't possibly over-allocate memory.
16207 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16208 (gif_memory_source):
16209 Use ptrdiff_t, not int or size_t, to record sizes.
16210 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16211 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16212 either works, as we prefer signed integers.
16213 (tiff_read_from_memory, tiff_write_from_memory):
16214 Return tsize_t, not size_t, since that's what the TIFF API wants.
16215 (tiff_read_from_memory): Don't fail simply because the read would
16216 go past EOF; instead, return a short read.
16217 (tiff_load): Omit no-longer-needed casts.
16218 (Fimagemagick_types): Don't assume size fits into 'int'.
16220 Improve hashing quality when configured --with-wide-int.
16221 * fns.c (hash_string): New function, taken from sxhash_string.
16222 Do not discard information about ASCII character case; this
16223 discarding is no longer needed.
16224 (sxhash-string): Use it. Change sig to match it. Caller changed.
16225 * lisp.h: Declare it.
16226 * lread.c (hash_string): Remove, since we now use fns.c's version.
16227 The fns.c version returns a wider integer if --with-wide-int is
16228 specified, so this should help the quality of the hashing a bit.
16230 * emacs.c: Integer overflow minor fix.
16231 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16232 Define only if GNU_LINUX.
16233 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16235 * dispnew.c: Integer signedness and overflow fixes.
16236 Remove unnecessary forward decls, that were a maintenance hassle.
16237 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16239 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16240 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16241 (prepare_desired_row, line_draw_cost):
16242 Use int, not unsigned, where either works.
16243 (save_current_matrix, restore_current_matrix):
16244 Use ptrdiff_t, not size_t, where either works.
16245 (init_display): Check for overflow more accurately, and without
16246 relying on undefined behavior.
16248 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16249 Remove, replacing with the new symbols in lisp.h. All uses changed.
16250 * fileio.c (make_temp_name):
16251 * filelock.c (lock_file_1, lock_file):
16252 * xdisp.c (message_dolog):
16253 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16254 Use pMd etc. instead.
16255 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16256 replacing the pWIDE etc. symbols removed from editfns.c.
16258 * keyboard.h (num_input_events): Now uintmax_t.
16259 This is (very slightly) less likely to mess up due to wraparound.
16262 * buffer.c: Integer signedness fixes.
16263 (alloc_buffer_text, enlarge_buffer_text):
16264 Use ptrdiff_t rather than size_t when either will do, as we prefer
16267 * alloc.c: Integer signedness and overflow fixes.
16268 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16269 (__malloc_size_t): Default to size_t, not to int.
16270 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16271 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16272 Prefer ptrdiff_t to size_t when either would do, as we prefer
16274 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16275 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16276 Now const. Initialize with values that are in range even if char
16278 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16279 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16280 These functions do the right thing with sizes > 2**32.
16281 (check_depth): Now ptrdiff_t, not int.
16282 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16283 Adjust to new way of storing sizes. Check for size overflow bugs
16285 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16286 slightly wrong anyway, as it missed one instance of
16287 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16288 (refill_memory_reserve): Omit needless cast to size_t.
16289 (mark_object_loop_halt): Mark as externally visible.
16291 * xselect.c: Integer signedness and overflow fixes.
16292 (Fx_register_dnd_atom, x_handle_dnd_message):
16293 Use ptrdiff_t, not size_t, since we prefer signed.
16294 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16295 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16296 x_dnd_atoms_size and x_dnd_atoms_length.
16298 * doprnt.c: Prefer signed to unsigned when either works.
16300 * doprnt.c (doprnt):
16302 * xdisp.c (vmessage):
16303 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16304 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16305 prefer signed arithmetic to avoid comparison confusion.
16306 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16307 but is a bit tricky.
16309 Assume freestanding C89 headers, string.h, stdlib.h.
16310 * data.c, doprnt.c, floatfns.c, print.c:
16311 Include float.h unconditionally.
16312 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16313 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16314 * regex.c: Likewise for stddef.h, string.h.
16315 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16316 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16317 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16318 (STDC_HEADERS): Remove obsolete defines.
16319 * sysdep.c: Include limits.h unconditionally.
16321 Assume support for memcmp, memcpy, memmove, memset.
16322 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16323 * regex.c (memcmp, memcpy):
16324 Remove; we assume C89 now.
16326 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16327 (__malloc_safe_bcopy): Remove; no longer needed.
16329 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16330 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16331 well either way, and we prefer signed to unsigned.
16333 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16335 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16336 closes the connection while we're reading (bug#9182).
16338 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16340 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16341 are specified (Bug#9168).
16343 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16345 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16346 Found by GCC static checking and --with-wide-int on a 32-bit host.
16348 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16350 * xdisp.c (compute_display_string_pos): Fix logic of caching
16351 previous display string position. Initialize cached_prev_pos to
16352 -1. Fixes slow-down at the beginning of a buffer.
16354 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16356 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16357 for attrs[LFACE_FONTSET_INDEX].
16359 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16361 * xml.c (parse_region): Remove unused local
16362 that was recently introduced.
16364 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16366 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16367 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16369 * xdisp.c (move_it_in_display_line_to): Record the best matching
16370 position for TO_CHARPOS while scanning the line, and restore it on
16371 exit if none of the characters scanned was an exact match.
16372 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16373 when exact match is impossible due to invisible text, and the
16374 lines are truncated.
16376 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16378 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16381 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16383 Fix a significant slow-down of cursor motion with C-n, C-p,
16384 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16385 auto-repeat under bidi redisplay in fontified buffers.
16386 * xdisp.c (compute_stop_pos_backwards): New function.
16387 (next_element_from_buffer): Call compute_stop_pos_backwards to
16388 find a suitable prev_stop when we find ourselves before
16390 (reseat): Don't look for prev_stop, as that could mean a very long
16392 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16393 <cached_disp_overlay_modiff>: Cache for last found display string
16395 (compute_display_string_pos): Return the cached position if asked
16396 about the same buffer in the same area of character positions, and
16397 the buffer wasn't changed since the time the display string
16398 position was cached.
16400 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16402 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16403 is an integer, which is important for empty lines. (Bug#9149)
16405 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16407 * frame.c (Fmodify_frame_parameters): In tty case, update the
16408 default face if necessary (Bug#4238).
16410 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16412 * editfns.c (Fstring_to_char): No need to explain what a character
16413 is in the docstring (Bug#6576).
16415 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16417 * xml.c (parse_region): Make sure we always return a tree.
16419 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16421 * xml.c (parse_region): If a document contains only comments,
16424 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16426 * xml.c (make_dom): Return comments, too.
16428 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16431 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16432 and the surrounding thread.
16433 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16434 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16435 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16437 * s/openbsd.h (BROKEN_SIGIO): Define.
16438 * unexelf.c (unexec) [__OpenBSD__]:
16439 Don't update the .mdebug section of the Alpha COFF symbol table.
16441 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16443 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16446 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16448 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16449 This fixes some race conditions on the permissions of any newly
16452 * alloc.c (valid_pointer_p): Use pipe, not open.
16453 This fixes some permissions issues when debugging.
16455 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16456 If fchown fails to set both uid and gid, try to set just gid,
16457 as that is sometimes allowed. Adjust the file's mode to eliminate
16458 setuid or setgid bits that are inappropriate if fchown fails.
16460 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16462 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16463 to compare Lisp_Objects.
16464 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16465 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16466 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16468 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16470 * lread.c (read_integer): Unread even EOF character.
16471 (read1): Likewise. Properly record start position of symbol.
16473 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16474 symbol character follows.
16476 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16478 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16479 This works around a problem with the previous change to Fcopy_file.
16480 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16481 and without this change, GCC might complain about discarding
16482 fchown's return value.
16484 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16486 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

16580 the iterator is before prev_stop.

17099 Random fixes. E.g., (random) never returned negative values.
17100 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17101 subseconds part to the entropy, as that's a bit more random.
17102 Prefer signed to unsigned, since the signedness doesn't matter and
17103 in general we prefer signed. When given a limit, use a
17104 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17105 latter isn't right if USE_2_TAGS_FOR_INTS.
17106 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17107 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17131 error be more correct.
17133 * fns.c (Frequire): Remove the mention of the .gz files, since

17150 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17151 Also (re)move comments that are misplaced or no longer relevant.

17253 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17254 signed bit field, as this assumption is not portable and it makes
17255 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17256 "char debug_on_exit : 1" as this is not portable either; instead,
17257 use the portable "unsigned int debug_on_exit : 1". Remove unused
17258 member evalargs. Remove obsolete comments about cc bombing out.

17422 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17424 Integer and buffer overflow fixes (Bug#8873).
17426 * print.c (printchar, strout): Check for string overflow.
17427 (PRINTPREPARE, printchar, strout):
17428 Don't set size unless allocation succeeds.
17430 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17431 for sizes. Check for string overflow more accurately.
17432 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17434 * macros.c: Integer and buffer overflow fixes.
17435 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17436 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17437 Use ptrdiff_t, not int, for sizes.
17438 Don't increment bufsize until after realloc succeeds.
17439 Check for size-calculation overflow.
17440 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17442 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17444 * lread.c: Integer overflow fixes.
17445 (read_integer): Radix is now EMACS_INT, not int,
17446 to improve quality of diagnostics for out-of-range radices.
17447 Calculate buffer size correctly for out-of-range radices.
17448 (read1): Check for integer overflow in radices, and in
17449 read-circle numbers.
17450 (read_escape): Avoid int overflow.
17451 (Fload, openp, read_buffer_size, read1)
17452 (substitute_object_recurse, read_vector, read_list, map_obarray):
17453 Use ptrdiff_t, not int, for sizes.

17468 2011-06-22 Leo Liu <sdl.web@gmail.com>
17470 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17471 Move to minibuffer.el.
17473 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17475 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17476 The following patches are for when GLYPH_DEBUG && !XASSERT.
17477 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17478 * dispnew.c (flush_stdout):
17479 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17480 Mark as externally visible.
17481 * dispnew.c (check_window_matrix_pointers): Now static.
17482 * dispnew.c (window_to_frame_vpos):
17483 * xfns.c (unwind_create_frame):
17484 * xterm.c (x_check_font): Remove unused local.
17485 * scroll.c (CHECK_BOUNDS):
17486 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17487 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17488 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17489 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17490 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17492 (debug_method_add): Use va_list and vsprintf rather than relying
17493 on undefined behavior with wrong number of arguments.
17494 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17495 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17496 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17497 since we're not interested in debugging glyphs with old libraries.
17498 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17499 GCC 4.6.0's static checking.
17501 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17503 Integer overflow and signedness fixes (Bug#8873).

17517 * xfaces.c (load_pixmap):
17518 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17519 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17520 (.bitmaps_last, struct x_output.icon_bitmap):
17521 Use ptrdiff_t, not int, for bitmap indexes.
17522 (x_allocate_bitmap_record): Check for size overflow.
17523 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17525 Use ptrdiff_t, not int, for overlay counts.
17526 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17527 * editfns.c (overlays_around, get_pos_property):
17528 * textprop.c (get_char_property_and_overlay):
17529 * xdisp.c (next_overlay_change, note_mouse_highlight):
17530 * xfaces.c (face_at_buffer_position):
17531 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17532 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17533 (Fnext_overlay_change, Fprevious_overlay_change)
17534 (mouse_face_overlay_overlaps, Foverlays_in):
17535 Use ptrdiff_t, not int, for sizes.
17536 (overlays_at, overlays_in): Check for size-calculation overflow.
17538 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17540 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17541 (x_session_initialize): Do not assume string length fits in int.
17543 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17544 This is unlikely, but can occur if DPI is outlandish.
17546 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17547 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17549 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17550 * xrdb.c (magic_file_p, search_magic_path):
17551 Omit last arg SUFFIX; it was always 0. All callers changed.
17552 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17554 * xfont.c (xfont_match): Avoid need for strlen.
17556 * xfns.c: Don't assume strlen fits in int.
17557 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17559 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17560 not unsigned long, as we prefer signed integers. All callers changed.
17561 Detect integer overflow in repeat count.
17562 (message_dolog): Don't assume print length fits in 39 bytes.
17563 (display_mode_element): Don't assume strlen fits in int.
17565 * termcap.c: Don't assume sizes fit in int and never overflow.
17566 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17567 (gobble_line): Check for size-calculation overflow.
17569 * minibuf.c (Fread_buffer):
17570 * lread.c (intern, intern_c_string):
17571 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17572 Don't assume string length fits in int.
17574 * keyboard.c (parse_tool_bar_item):
17575 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17577 * font.c: Don't assume string length fits in int.
17578 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17579 Use ptrdiff_t, not int.
17580 (font_intern_prop): Don't assume string length fits in int.
17581 Don't assume integer property fits in fixnum.
17582 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17584 * filelock.c: Fix some buffer overrun and integer overflow issues.
17585 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17586 Reformulate so as not to need the command string.
17587 Invoke gzip -cd rather than gunzip, as it's more portable.
17588 (lock_info_type, lock_file_1, lock_file):
17589 Don't assume pid_t and time_t fit in unsigned long.
17590 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17591 (current_lock_owner): Prefer signed type for sizes.
17592 Use memcpy, not strncpy, where memcpy is what is really wanted.
17593 Don't assume (via atoi) that time_t and pid_t fit in int.
17594 Check for time_t and/or pid_t out of range, e.g., via a network share.
17595 Don't alloca where an auto var works fine.
17597 * fileio.c: Fix some integer overflow issues.
17598 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17599 Don't assume string length fits in int.
17600 (directory_file_name): Don't assume string length fits in long.
17601 (make_temp_name): Don't assume pid fits in int, or that its print
17602 length is less than 20.
17604 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17606 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17608 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17610 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17611 We prefer signed integers, even for size calculations.
17613 * emacs.c: Don't assume string length fits in 'int'.
17614 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17615 (main): Don't invoke strlen when not needed.
17617 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

17620 * callproc.c (getenv_internal_1, getenv_internal)
17621 (Fgetenv_internal):
17622 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17624 * lread.c (invalid_syntax): Omit length argument.
17625 All uses changed. This doesn't fix a bug, but it simplifies the
17626 code away from its former Hollerith-constant appearance, and it's
17627 one less 'int' to worry about when looking at integer-overflow issues.
17628 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17630 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17631 This didn't break anything, but it didn't help either.
17632 It's confusing to put a bogus integer in a place where the actual
17633 value does not matter.
17634 (LIST_END_P): Remove unused macro and its bogus comment.
17635 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17637 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17638 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17640 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17641 We prefer signed types, and the value cannot exceed the EMACS_INT
17642 range anyway (because otherwise the length would not be representable).
17643 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17644 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17645 This avoids a GCC warning when WIDE_EMACS_INT.
17647 * indent.c (sane_tab_width): New function.
17648 (current_column, scan_for_column, Findent_to, position_indentation)
17649 (compute_motion): Use it. This is just for clarity.
17650 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17652 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17654 * lisp.h (lint_assume): New macro.
17655 * composite.c (composition_gstring_put_cache):
17656 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17658 * editfns.c, insdel.c:
17659 Omit unnecessary forward decls, to simplify future changes.
17661 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17663 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17665 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17666 Use much-faster test for byte-length change.
17667 Don't assume string byte-length fits in 'int'.
17668 Check that character arg fits in 'int'.
17669 (mapcar1): Declare byte as byte, for clarity.
17671 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17673 * fns.c (concat): Catch string overflow earlier.
17674 Do not rely on integer wraparound.
17676 * dispextern.h (struct it.overlay_strings_charpos)
17677 (struct it.selective): Now EMACS_INT, not int.
17678 * xdisp.c (forward_to_next_line_start)
17679 (back_to_previous_visible_line_start)
17680 (reseat_at_next_visible_line_start, next_element_from_buffer):
17681 Don't arbitrarily truncate the value of 'selective' to int.
17683 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17685 * composite.c: Don't truncate sizes to 'int'.
17686 (composition_gstring_p, composition_reseat_it)
17687 (composition_adjust_point): Use EMACS_INT, not int.
17688 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17689 not EMACS_UINT, for indexes.
17691 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17693 * buffer.c: Include <verify.h>.
17694 (struct sortvec.priority, struct sortstr.priority):
17695 Now EMACS_INT, not int.
17696 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17697 (struct sortstr.size, record_overlay_string)
17698 (struct sortstrlist.size, struct sortlist.used):
17699 Don't truncate size to int.
17700 (record_overlay_string): Check for size-calculation overflow.
17701 (init_buffer_once): Check at compile-time, not run-time.
17703 2011-06-22 Jim Meyering <meyering@redhat.com>
17705 Don't leak an XBM-image-sized buffer
17706 * image.c (xbm_load): Free the image buffer after using it.
17708 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17711 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17712 that Sun C diagnosed.
17713 * fns.c (secure_hash): Fix pointer signedness issue.
17714 * intervals.c (static_offset_intervals): New function.
17715 (offset_intervals): Use it.
17717 2011-06-21 Leo Liu <sdl.web@gmail.com>
17720 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17723 * fns.c (secure_hash): Rename from crypto_hash_function and change
17724 the first arg to accept symbols.
17725 (Fsecure_hash): New primitive.
17726 (syms_of_fns): New symbols.
17728 2011-06-20 Deniz Dogan <deniz@dogan.se>
17730 * process.c (Fset_process_buffer): Clarify return value in
17733 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17735 * dispnew.c (add_window_display_history): Use BVAR.
17737 * xdisp.c (debug_method_add): Use BVAR.
17738 (check_window_end, dump_glyph_matrix, dump_glyph)
17739 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17741 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17744 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17745 check till after the cache is created in init_frame_faces.
17747 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17749 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17751 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17753 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17754 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17755 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17757 Improve buffer-overflow checking (Bug#8873).
17758 * fileio.c (Finsert_file_contents):
17759 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17760 Remove the old (too-loose) buffer overflow checks.
17761 They weren't needed, since make_gap checks for buffer overflow.
17762 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17763 The old code merely checked for Emacs fixnum overflow, and relied
17764 on undefined (wraparound) behavior. The new code avoids undefined
17765 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17767 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17768 Tune. Don't use wider integers than needed. Don't use alloca.
17769 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17771 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17773 * insdel.c, lisp.h (buffer_overflow): New function.
17774 (insert_from_buffer_1, replace_range, replace_range_2):
17775 * insdel.c (make_gap_larger):
17776 * editfns.c (Finsert_char):
17777 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17779 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17781 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17783 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17785 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17786 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17788 * fileio.c: Don't assume EMACS_INT fits in off_t.
17789 (emacs_lseek): New static function.
17790 (Finsert_file_contents, Fwrite_region): Use it.
17791 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17793 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17795 * fns.c: Don't overflow int when computing a list length.
17796 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17797 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17798 truncation on 64-bit hosts. Check for QUIT every
17799 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17800 faster and is responsive enough.
17801 (Flength): Report an error instead of overflowing an integer.
17802 (Fsafe_length): Return a float if the value is not representable
17803 as a fixnum. This shouldn't happen except in contrived situations.
17804 (Fnthcdr, Fsort): Don't assume list length fits in int.
17805 (Fcopy_sequence): Don't assume vector length fits in int.
17807 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17808 (header_size, word_size): New constants.
17809 (allocate_vectorlike): Don't check size overflow here.
17810 (allocate_vector): Check it here instead, since this is the only
17811 caller of allocate_vectorlike that could cause overflow.
17812 Check that the new vector's length is representable as a fixnum.
17814 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17815 The previous code was bogus. For example, next_almost_prime (32)
17816 returned 39, which is undesirable as it is a multiple of 3; and
17817 next_almost_prime (24) returned 25, which is a multiple of 5 so
17818 why was the code bothering to check for multiples of 7?
17820 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17822 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17824 Variadic C functions now count arguments with ptrdiff_t.
17825 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17826 Back then I didn't know that the Emacs coding style prefers signed int.
17827 Also, in the meantime I found a few more instances where arguments
17828 were being counted with int, which may truncate counts on 64-bit
17829 machines, or EMACS_INT, which may be unnecessarily wide.
17830 * lisp.h (struct Lisp_Subr.function.aMANY)
17831 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17832 Arg counts are now ptrdiff_t, not size_t.
17833 All variadic functions and their callers changed accordingly.
17834 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17835 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17836 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17837 * callint.c (Fcall_interactively): Check arg count for overflow,
17838 to avoid potential buffer overrun. Use signed char, not 'int',
17839 for 'varies' array, so that we needn't bother to check its size
17840 calculation for overflow.
17841 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17842 * eval.c (apply_lambda):
17843 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17844 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17845 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17847 * callint.c (Fcall_interactively): Don't use index var as event count.
17849 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17850 * mem-limits.h (SIZE): Remove; no longer used.
17852 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17854 Remove unnecessary casts.
17855 * xterm.c (x_term_init):
17856 * xfns.c (x_set_border_pixel):
17857 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17858 These aren't needed now that we assume ANSI C.
17860 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17861 It's more likely to cause problems (due to unsigned overflow)
17864 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17866 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17868 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17870 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17872 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17874 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17876 GLYPH_CODE_FACE returns EMACS_INT, not int.
17877 * dispextern.h (merge_faces):
17878 * xfaces.c (merge_faces):
17879 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17880 Don't assume EMACS_INT fits in int.
17882 * character.h (CHAR_VALID_P): Remove unused parameter.
17883 * fontset.c, lisp.h, xdisp.c: All uses changed.
17885 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17887 * fns.c (concat): Minor tuning based on overflow analysis.
17888 This doesn't fix any bugs. Use int to hold character, instead
17889 of constantly refetching from Emacs object. Use XFASTINT, not
17890 XINT, for value known to be a character. Don't bother comparing
17891 a single byte to 0400, as it's always less.
17893 * floatfns.c (Fexpt):
17894 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17896 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17899 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17901 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17902 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17903 incorrectly succeed when S was a string, because 4294967386 was
17904 truncated before it was used.
17906 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17907 Otherwise, an out-of-range integer could cause undefined behavior
17910 * composite.c: Use int, not EMACS_INT, for characters.
17911 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17912 EMACS_INT, for values that are known to be in character range.
17913 This doesn't fix any bugs but is the usual style inside Emacs and
17914 may generate better code on 32-bit machines.
17916 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17917 This is for reasons similar to the recent CHAR_STRING fix.
17918 * charset.c (Fencode_char): Check that character arg is actually
17919 a character. Pass an int to ENCODE_CHAR.
17920 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17921 wider than 'int', as a compile-time check to prevent future regressions
17924 * character.c (char_string): Remove unnecessary casts.
17926 Make sure a 64-bit char is never passed to CHAR_STRING.
17927 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17928 by silently ignoring the top 32 bits, allowing some values
17929 that were far too large to be valid characters.
17930 * character.h: Include <verify.h>.
17931 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17932 arguments are no wider than unsigned, as a compile-time check
17933 to prevent future regressions in this area.
17935 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17936 (Fsubst_char_in_region):
17938 * xdisp.c (decode_mode_spec_coding):
17939 Adjust to CHAR_STRING's new requirement.
17940 * editfns.c (Finsert_char, Fsubst_char_in_region):
17941 * fns.c (concat): Check that character args are actually
17942 characters. Without this test, these functions did the wrong
17943 thing with wildly out-of-range values on 64-bit hosts.
17945 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17946 These casts should not be needed on 32-bit hosts, either.
17947 * keyboard.c (read_char):
17948 * lread.c (Fload): Remove casts to unsigned.
17950 * lisp.h (UNSIGNED_CMP): New macro.
17951 This fixes comparison bugs on 64-bit hosts.
17952 (ASCII_CHAR_P): Use it.
17953 * casefiddle.c (casify_object):
17954 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17955 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17956 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17957 * dispextern.h (FACE_FROM_ID):
17958 * keyboard.c (read_char): Use UNSIGNED_CMP.
17960 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17961 not to EMACS_INT, to avoid GCC warning.
17963 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17965 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17966 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17967 isn't needed on 32-bit machines.
17969 * buffer.c (Fgenerate_new_buffer_name):
17970 Use EMACS_INT for count, not int.
17971 (advance_to_char_boundary): Return EMACS_INT, not int.
17973 * data.c (Qcompiled_function): Now static.
17975 * window.c (window_body_lines): Now static.
17977 * image.c (gif_load): Rename local to avoid shadowing.
17979 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17980 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17981 * alloc.c (make_save_value): Integer argument is now of type
17982 ptrdiff_t, not int.
17983 (mark_object): Use ptrdiff_t, not int.
17984 * lisp.h (pD): New macro.
17985 * print.c (print_object): Use it.
17987 * alloc.c: Use EMACS_INT, not int, to count objects.
17988 (total_conses, total_markers, total_symbols, total_vector_size)
17989 (total_free_conses, total_free_markers, total_free_symbols)
17990 (total_free_floats, total_floats, total_free_intervals)
17991 (total_intervals, total_strings, total_free_strings):
17992 Now EMACS_INT, not int. All uses changed.
17993 (Fgarbage_collect): Compute overall total using a double, so that
17994 integer overflow is less likely to be a problem. Check for overflow
17995 when converting back to an integer.
17996 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17997 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17998 These were 'int' variables that could overflow on 64-bit hosts;
17999 they were never used, so remove them instead of repairing them.
18000 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18001 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18002 Previously, this ceilinged at INT_MAX, but that doesn't work on
18004 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18006 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18007 (allocate_vectorlike): Check for ptrdiff_t overflow.
18008 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18009 when a (possibly-narrower) signed value would do just as well.
18010 We prefer using signed arithmetic, to avoid comparison confusion.
18012 * alloc.c: Catch some string size overflows that we were missing.
18013 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18014 for convenience in STRING_BYTES_MAX.
18015 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18016 The definition here is exact; the one in lisp.h was approximate.
18017 (allocate_string_data): Check for string overflow. This catches
18018 some instances we weren't catching before. Also, it catches
18019 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18020 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18021 and ptrdiff_t and EMACS_INT are both 64 bits.
18023 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18024 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18025 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18027 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18029 * alloc.c (Fmake_string): Check for out-of-range init.
18031 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18033 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18035 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18037 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18038 xg_get_default_scrollbar_width.
18040 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18041 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18042 (style_changed_cb): Call update_theme_scrollbar_width and call
18043 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18044 all frames (Bug#8505).
18045 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18046 Call gtk_window_set_resizable if HAVE_GTK3.
18047 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18048 and height if HAVE_GTK3 (Bug#8505).
18049 (scroll_bar_width_for_theme): New variable.
18050 (update_theme_scrollbar_width): New function.
18051 (xg_get_default_scrollbar_width): Move code to
18052 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18053 (xg_initialize): Call update_theme_scrollbar_width.
18055 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18057 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18059 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18061 * frame.c (make_frame): Call other_buffer_safely instead of
18064 * window.c (temp_output_buffer_show): Call display_buffer with
18065 second argument Vtemp_buffer_show_specifiers and reset latter
18066 immediately after the call.
18067 (Vtemp_buffer_show_specifiers): New variable.
18068 (auto_window_vscroll_p, next_screen_context_lines)
18069 (Vscroll_preserve_screen_position): Remove leading asterisks from
18072 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18074 Fix minor problems found by GCC 4.6.0 static checking.
18075 * buffer.c (Qclone_number): Remove for now, as it's unused.
18076 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18077 (record_buffer): Remove unused local.
18078 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18079 (set_frame_buffer_list): Remove; unused.
18080 * frame.h (other_visible_frames): Remove decl.
18081 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18082 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18083 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18085 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18086 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18087 Define only if HAVE_GPM.
18088 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18089 (update_hints_inhibit): Remove; never set. All uses removed.
18090 * widgetprv.h (emacsFrameClassRec): Remove decl.
18091 * window.c (delete_deletable_window): Now returns void, since it
18092 wasn't returning anything.
18093 (compare_window_configurations): Remove unused locals.
18094 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18095 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18096 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18097 the same widths as pointers. This follows up on the 2011-05-06 patch.
18098 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18099 * xterm.h: Likewise.
18100 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

18105 (LISP_H): Add lib/intprops.h.
18107 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18109 * image.c (gif_load): Add animation frame delay to the metadata.
18110 (syms_of_image): Use DEFSYM. New symbol `delay'.
18112 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18114 * window.c (delete_deletable_window): Re-add.
18115 (Fset_window_configuration): Rewrite to handle dead buffers and
18116 consequently deletable windows.
18117 (window_tree, Fwindow_tree): Remove. Supply functionality in
18119 (compare_window_configurations): Simplify code.
18121 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18123 * image.c (imagemagick_load_image): Fix type mismatch.
18124 (Fimagemagick_types): Likewise.
18126 * window.h (replace_buffer_in_windows): Declare.
18128 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18130 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18131 Qclone_number. Remove external declaration of Qdelete_window.
18132 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18134 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18135 Run Qbuffer_list_update_hook if allowed.
18136 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18137 buffer list implementation.
18138 (other_buffer_safely): New function.
18139 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18140 calls to replace_buffer_in_windows and
18141 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18143 (record_buffer): Inhibit quitting and rewrite using quittable
18144 functions. Run Qbuffer_list_update_hook if allowed.
18145 (Frecord_buffer, Funrecord_buffer): New functions.
18146 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18147 Move switch-to-buffer to window.el.
18148 (bury-buffer): Move to window.el.
18149 (Vbuffer_list_update_hook): New variable.
18151 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18154 * window.h (resize_frame_windows): Move up in code.
18155 (Fwindow_frame): Remove EXFUN.
18156 (replace_buffer_in_all_windows): Remove prototype.
18157 (replace_buffer_in_windows_safely): Add prototype.
18159 * window.c: Declare Qdelete_window static again. Move down
18160 declaration of select_count.
18161 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18162 (Fother_window): Move to window.el.
18163 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18164 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18165 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18167 (replace_buffer_in_windows): Implement by calling
18168 Qreplace_buffer_in_windows.
18169 (replace_buffer_in_all_windows): Remove with some functionality
18170 moved into replace_buffer_in_windows_safely.
18171 (replace_buffer_in_windows_safely): New function.
18172 (select_window_norecord, select_frame_norecord): Move in front
18173 of run_window_configuration_change_hook. Remove now obsolete
18175 (Fset_window_buffer): Rewrite doc-string.
18176 Call Qrecord_window_buffer.
18177 (keys_of_window): Move binding for other-window to window.el.
18179 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18181 * dispextern.h (struct image): Replace data member, whose int_val
18182 and ptr_val fields were not used by anything, with a single
18185 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18186 (gif_clear_image, gif_load, imagemagick_load_image)
18187 (gs_clear_image, gs_load): Callers changed.

18620 (display_prop_intangible_p): Reimplement to call
18621 handle_display_spec instead of single_display_spec_intangible_p.

18626 lists with the argument STRING its top-level element.
18627 (display_prop_string_p): Fix the condition for processing a

18633 value of a `display' property is a "replacing spec".
18634 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18635 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18636 the display property, but just return a value indicating whether
18637 the display property will replace the characters it covers.
18638 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18639 frame_window_p members of struct bidi_it.

18663 All callers changed. (Bug#8762)
18665 * gnutls.c: Use Emacs's memory allocators.
18666 Without this change, the gnutls library would invoke malloc etc.
18667 directly, which causes problems on non-SYNC_INPUT hosts, and which
18668 runs afoul of improving memory_full behavior. (Bug#8761)
18669 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18670 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18671 xfree instead of the default malloc, realloc, free.
18672 (Fgnutls_boot): No need to check for memory allocation failure,
18673 since xmalloc does that for us.

18693 * lisp.h (struct Lisp_Hash_Table):
18694 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18695 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18696 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18697 * alloc.c (allocate_vectorlike):
18698 Check for overflow in vector size calculations.
18699 * ccl.c (ccl_driver):
18700 Check for overflow when converting EMACS_INT to int.
18701 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18702 need to be updated by these changes.
18703 * fns.c (make_hash_table, maybe_resize_hash_table):
18704 Check for integer overflow with large hash tables.
18705 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18706 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18707 (SXHASH_REDUCE): New macro.
18708 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18709 Use it instead of discarding useful hash info with large hash values.
18710 (sxhash_float): New function.
18711 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18712 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18713 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18714 Rewrite to use FIXNUM_BITS, as this simplifies things.
18715 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18716 Adjust signatures to match updated version of code.
18717 (consing_since_gc): Now EMACS_INT, since a single hash table can
18718 use more than INT_MAX bytes.
18720 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18722 Make it possible to build with GCC-4.6+ -O2 -flto.

18734 Update dependencies.
18736 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18738 * data.c (init_data): Remove code for UTS, this system is not
18741 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18743 Don't force ./temacs to start in terminal mode.
18745 * frame.c (make_initial_frame): Initialize faces in all cases, not
18746 only when CANNOT_DUMP is defined.
18747 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18749 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18751 * dispnew.c (add_window_display_history): Use const for the string
18752 pointer. Remove declaration, not needed.
18754 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18756 Use 'inline', not 'INLINE'.
18757 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18758 * alloc.c, fontset.c (INLINE): Remove.
18759 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18760 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18761 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18762 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18763 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18765 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18767 Make it possible to run ./temacs.
18769 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18770 syms_of_callproc does the same thing. Remove test for
18771 "initialized", do it in the caller.
18772 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18774 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18776 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18777 (read_minibuf): Use get_minibuffer.
18778 (syms_of_minibuf): Use DEFSYM.
18779 (Qmetadata): New var.
18780 * data.c (Qbuffer): Don't make it static.
18781 (syms_of_data): Use DEFSYM.
18783 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18785 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18786 (CCL_CODE_MIN): New macro.
18788 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18790 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18792 * eval.c (Qdebug): Now static.
18793 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18794 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18795 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18797 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18799 * image.c: Various fixes to ImageMagick code comments.
18800 (Fimagemagick_types): Doc fix.
18802 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18804 Minor fixes prompted by GCC 4.6.0 warnings.
18806 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18808 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18809 (x_clipboard_manager_save_all): Move extern decl to ...
18810 * xterm.h: ... here, so that it can be checked for consistency.
18812 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18814 * xselect.c (x_clipboard_manager_save_frame)
18815 (x_clipboard_manager_save_all): New functions.
18816 (Fx_clipboard_manager_save): Lisp function deleted.
18818 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18819 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18821 * xterm.h: Update prototype.
18823 2011-05-28 William Xu <william.xwl@gmail.com>
18825 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18826 exiting (Bug#8239).
18828 2011-05-28 Jim Meyering <meyering@redhat.com>
18830 Avoid a sign-extension bug in crypto_hash_function.
18831 * fns.c (to_uchar): Define.
18832 (crypto_hash_function): Use it to convert some newly-signed
18833 variables to unsigned, to avoid sign-extension bugs. For example,
18834 without this change, (md5 "truc") would evaluate to
18835 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18836 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18837 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18839 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18841 Integer overflow fixes.
18843 * dbusbind.c: Serial number integer overflow fixes.
18844 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18845 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18846 to hold a serial number that is too large for a fixnum.
18847 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18848 Check for serial numbers out of range. Decode any serial number
18849 that was so large that it became a float. (Bug#8722)
18851 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18852 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18853 Use XFASTINT rather than XUINT when numbers are nonnegative.
18854 (xd_append_arg, Fdbus_method_return_internal):
18855 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18856 arguments, check that Lisp number is nonnegative, rather than
18857 silently wrapping negative numbers around. (Bug#8722)
18858 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18861 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18863 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18865 ccl: Add integer overflow checks.
18866 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18867 (IN_INT_RANGE): New macros.
18868 (ccl_driver): Use them to check for integer overflow when
18869 decoding a CCL program. Many of the new checks are whether XINT (x)
18870 fits in int; it doesn't always, on 64-bit hosts. The new version
18871 doesn't catch all possible integer overflows, but it's an
18872 improvement. (Bug#8719)
18874 * alloc.c (make_event_array): Use XINT, not XUINT.
18875 There's no need for unsigned here.
18877 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18878 This follows up to the 2011-05-06 change that substituted uintptr_t
18879 for EMACS_INT. This case wasn't caught back then.
18881 Rework Fformat to avoid integer overflow issues.
18882 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18883 now (part of C89). Include <verify.h>.
18884 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18885 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18886 (Fformat): Avoid the prepass trying to compute sizes; it was only
18887 approximate and thus did not catch overflow reliably. Instead, walk
18888 through the format just once, formatting and computing sizes as we go,
18889 checking for integer overflow at every step, and allocating a larger
18890 buffer as needed. Keep track separately whether the format is
18891 multibyte. Keep only the most-recently calculated precision, rather
18892 than them all. Record whether each argument has been converted to
18893 string. Use EMACS_INT, not int, for byte and char and arg counts.
18894 Support field widths and precisions larger than INT_MAX. Avoid
18895 sprintf's undefined behavior with conversion specifications such as %#d
18896 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18897 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18898 formatting out-of-range floating point numbers with int
18899 formats. (Bug#8668)
18901 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18903 * data.c: Avoid integer truncation in expressions involving floats.
18904 * data.c: Include <intprops.h>.
18905 (arith_driver): When there's an integer overflow in an expression
18906 involving floating point, convert the integers to floating point
18907 so that the resulting value does not suffer from catastrophic
18908 integer truncation. For example, on a 64-bit host (* 4
18909 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18910 Do not rely on undefined behavior after integer overflow.
18912 merge count_size_as_multibyte, parse_str_to_multibyte
18913 * character.c, character.h (count_size_as_multibyte):
18914 Rename from parse_str_to_multibyte; all uses changed.
18915 Check for integer overflow.
18916 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18917 since it's now a duplicate of the other. This is more of
18918 a character than a buffer op, so better that it's in character.c.
18919 * fns.c, print.c: Adjust to above changes.
18921 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18923 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18925 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18927 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18928 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18929 (x_clipboard_manager_save): Now static.
18930 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18932 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18933 (crypto_hash_function): Now static.
18934 Fix pointer signedness problems. Avoid unnecessary initializations.
18936 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18938 * termhooks.h (Vselection_alist): Make it terminal-local.
18940 * terminal.c (create_terminal): Initialize it.
18942 * xselect.c: Support for clipboard managers.
18943 (Vselection_alist): Move to termhooks.h as terminal-local var.
18944 (LOCAL_SELECTION): New macro.
18945 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18946 (symbol_to_x_atom): Remove gratuitous arg.
18947 (x_handle_selection_request, lisp_data_to_selection_data)
18948 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18949 (x_own_selection, x_get_local_selection, x_convert_selection):
18950 New arg, specifying work frame. Use terminal-local Vselection_alist.
18951 (some_frame_on_display): Delete unused function.
18952 (Fx_own_selection_internal, Fx_get_selection_internal)
18953 (Fx_disown_selection_internal, Fx_selection_owner_p)
18954 (Fx_selection_exists_p): New optional frame arg.
18955 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18956 (x_handle_selection_clear): Don't treat other terminals with the
18957 same keyboard specially. Use the terminal-local Vselection_alist.
18958 (x_clear_frame_selections): Use Frun_hook_with_args.
18960 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18962 * xterm.h: Add support for those atoms.
18964 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18966 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18967 (converted_selections, conversion_fail_tag): New global variables.
18968 (x_selection_request_lisp_error): Free the above.
18969 (x_get_local_selection): Remove unnecessary code.
18970 (x_reply_selection_request): Args changed; handle arbitrary array
18971 of converted selections stored in converted_selections.
18972 Separate the XChangeProperty and SelectionNotify steps.
18973 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18974 (x_convert_selection): New function.
18975 (x_handle_selection_event): Simplify.
18976 (x_get_foreign_selection): Don't ignore incoming requests while
18977 waiting for an answer; this will fail when we implement
18978 SAVE_TARGETS, and seems unnecessary anyway.
18979 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18980 (Vx_sent_selection_functions): Doc fix.
18982 2011-05-26 Leo Liu <sdl.web@gmail.com>
18984 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18986 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18988 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18990 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18991 for fringe update if it has periodic bitmap.
18992 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18993 and fringe_bitmap_periodic_p.
18995 * fringe.c (get_fringe_bitmap_data): New function.
18996 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18997 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18998 row. Mark glyph row for fringe update if periodicity changed.
19000 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19001 for fringe update unless it has periodic bitmap.
19003 2011-05-25 Kenichi Handa <handa@m17n.org>

19022 Remove macros that are defined and never used.
19023 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19025 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19027 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19028 (Fx_get_selection_internal): Minor cleanup.
19029 (Fx_own_selection_internal): Rename arguments for consistency with
19032 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

19056 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19058 * systime.h (Time): Define only if emacs is defined.
19059 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19060 where the include path doesn't have X11/X.h by default. See
19061 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19063 2011-05-20 Kenichi Handa <handa@m17n.org>
19065 * composite.c (find_automatic_composition): Fix previous change.
19067 2011-05-20 Glenn Morris <rgm@gnu.org>
19069 * lisp.mk: New file, split from Makefile.in.
19070 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19071 (shortlisp): Remove.
19072 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19074 2011-05-19 Glenn Morris <rgm@gnu.org>

19078 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19079 (lisp): Set the order to that of loadup.el.
19080 (shortlisp): Make it a copy of $lisp.
19081 (SOME_MACHINE_LISP): Remove.

19083 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19085 2011-05-18 Kenichi Handa <handa@m17n.org>
19087 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19088 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19089 (find_automatic_composition): Mostly rewrite for efficiency.
19091 2011-05-18 Juanma Barranquero <lekktu@gmail.com>

19095 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19097 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19098 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19100 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19102 Fix some integer overflow issues, such as string length overflow.
19104 * insdel.c (count_size_as_multibyte): Check for string overflow.
19106 * character.c (lisp_string_width): Check for string overflow.
19107 Use EMACS_INT, not int, for string indexes and lengths; in
19108 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19109 the resulting string length overflows an EMACS_INT; instead,
19110 report a string overflow if no precision given. When checking for
19111 precision exhaustion, use a check that cannot possibly have
19112 integer overflow. (Bug#8675)
19113 * character.h (lisp_string_width): Adjust to new signature.
19115 * alloc.c (string_overflow): New function.
19116 (Fmake_string): Use it. This doesn't change behavior, but saves
19117 a few bytes and will simplify future changes.
19118 * character.c (string_escape_byte8): Likewise.
19119 * lisp.h (string_overflow): New decl.
19121 Fixups, following up to the user-interface timestamp change.
19122 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19123 for UI timestamps, instead of unsigned long.
19124 * msdos.c (mouse_get_pos): Likewise.
19125 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19126 * w32gui.h (Time): Define by including "systime.h" rather than by
19127 declaring it ourselves. (Bug#8664)
19129 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19130 * image.c (clear_image_cache): Likewise.
19132 * term.c (term_mouse_position): Don't assume time_t wraparound.
19134 Be more systematic about user-interface timestamps.
19135 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19136 and sometimes 'EMACS_UINT', to represent these timestamps.
19137 This change causes it to use 'Time' uniformly, as that's what X uses.
19138 This makes the code easier to follow, and makes it easier to catch
19139 integer overflow bugs such as Bug#8664.
19140 * frame.c (Fmouse_position, Fmouse_pixel_position):
19141 Use Time, not unsigned long, for user-interface timestamps.
19142 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19143 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19144 * keyboard.h (last_event_timestamp): Likewise.
19145 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19146 * menu.h (xmenu_show): Likewise.
19147 * term.c (term_mouse_position): Likewise.
19148 * termhooks.h (struct input_event.timestamp): Likewise.
19149 (struct terminal.mouse_position_hook): Likewise.
19150 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19151 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19152 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19153 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19154 what it was before.
19155 * menu.h, termhooks.h: Include "systime.h", for Time.
19157 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19158 Don't assume that the difference between two unsigned long values
19159 can fit into an integer. At this point, we know button_down_time
19160 <= event->timestamp, so the difference must be nonnegative, so
19161 there's no need to cast the result if double-click-time is
19162 nonnegative, as it should be; check that it's nonnegative, just in
19163 case. This bug is triggered when events are more than 2**31 ms
19164 apart (about 25 days). (Bug#8664)
19166 * xselect.c (last_event_timestamp): Remove duplicate decl.
19167 (x_own_selection): Remove needless cast to unsigned long.
19169 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19170 that always fit in int. Use a sentinel instead of a counter, to
19171 avoid a temp and to allay GCC's concerns about possible int overflow.
19172 * frame.h (struct frame): Use int for menu_bar_items_used
19173 instead of EMACS_INT, since it always fits in int.
19175 * menu.c (grow_menu_items): Check for int overflow.
19177 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19179 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19180 Before, the code was not consistent. These values cannot exceed
19181 2**31 - 1 so there's no need to make them unsigned.
19182 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19183 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19184 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19186 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19188 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19189 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19190 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19191 presumably because the widths might not match.
19193 * window.c (size_window): Avoid needless test at loop start.
19195 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19197 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19199 2011-05-12 Drew Adams <drew.adams@oracle.com>
19201 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19203 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19205 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19206 `width' to `bar_area_x' and `bar_area_width', respectively.
19207 (x_scroll_run): Take account of fringe background extension.
19209 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19210 Rename local vars `left' and `width' to `bar_area_x' and
19211 `bar_area_width', respectively.
19212 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19213 background extension.
19215 2011-05-10 Jim Meyering <meyering@redhat.com>
19217 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19219 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19221 * image.c (Finit_image_library): Return t for built-in image types,
19222 like pbm and xbm. (Bug#8640)
19224 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19226 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19228 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19230 * w32console.c (Fset_screen_color): Doc fix.
19231 (Fget_screen_color): New function.
19232 (syms_of_ntterm): Defsubr it.
19234 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19235 unlink the temporary file if Fcall_process didn't create it in the
19237 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19238 child process will be redirected to a file specified with `:file'.
19239 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19240 cue to call_process_cleanup not to close that handle.
19242 2011-05-07 Ben Key <bkey76@gmail.com>
19244 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19245 one of two shell specific rules, either bootstrap-temacs-CMD or
19246 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19247 to the previous implementation of the bootstrap-temacs rule.
19248 The bootstrap-temacs-CMD rule is similar to the previous
19249 implementation of the bootstrap-temacs rule except that it
19250 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19253 These changes, along with some changes to nt/configure.bat,
19254 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19255 earlier fix to add support for --cflags and --ldflags options
19256 that include quotes so that it works whether make uses cmd or
19259 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19261 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19262 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19264 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19265 a string. Handle both cases.
19266 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19267 (Fdbus_register_method): Use Qinvalid_function.
19269 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19271 * makefile.w32-in: Update dependencies.
19272 (LISP_H): Add inttypes.h and stdin.h.
19273 (PROCESS_H): Add unistd.h.
19275 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19277 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19278 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19280 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19282 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19284 * term.c (vfatal): Remove stray call to va_end.
19285 It's not needed and the C Standard doesn't allow it here anyway.
19287 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19288 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19290 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19293 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19295 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19297 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19299 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19301 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19303 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19304 * charset.c (Fdefine_charset_internal): Don't initialize
19305 charset.code_space[15]. The value was garbage, on hosts with
19306 32-bit int (Bug#8600).
19308 * lread.c (read_integer): Be more consistent with string-to-number.
19309 Use string_to_number to do the actual conversion; this avoids
19310 rounding errors and fixes some other screwups. Without this fix,
19311 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19312 (digit_to_number): Move earlier, for benefit of read_integer.
19313 Return -1 if the digit is out of range for the base, -2 if it is
19314 not a digit in any supported base. (Bug#8602)
19316 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19318 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19319 to match comment at start of function. This also removes a
19320 GCC warning about overflow in a 32+64-bit port.
19322 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19324 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19325 Reported by Stefan Monnier in
19326 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19327 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19328 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19330 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19331 (EMACS_UINTPTR): Likewise, with uintptr_t.
19333 * lisp.h: Prefer 64-bit EMACS_INT if available.
19334 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19335 on 32-bit hosts that have 64-bit int, so that they can access
19337 However, temporarily disable this change unless the temporary
19338 symbol WIDE_EMACS_INT is defined.
19340 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19342 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19343 This removes an assumption that EMACS_INT and long are the same
19344 width as pointers. The assumption is true for Emacs porting targets
19345 now, but we want to make other targets possible.
19346 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19347 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19348 In the rest of the code, change types of integers that hold casted
19349 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19350 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19351 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19352 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19353 No need to cast type when ORing.
19354 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19355 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19356 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19357 assume EMACS_INT is the same width as char *.
19358 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19359 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19360 Remove no-longer-needed casts.
19361 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19362 (xg_tool_bar_help_callback, xg_make_tool_item):
19363 Use EMACS_INTPTR to hold an integer
19364 that will be cast to void *; this can avoid a GCC warning
19365 if EMACS_INT is not the same width as void *.
19366 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19367 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19368 (current_message_1, set_message_1):
19369 Use a local to convert to proper width without a cast.
19370 * xmenu.c (dialog_selection_callback): Likewise.
19372 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19373 Also, don't assume VALBITS / RAND_BITS is less than 5,
19374 and don't rely on undefined behavior when shifting a 1 left into
19376 * lisp.h (get_random): Change signature to match.
19378 * lread.c (hash_string): Use size_t, not int, for hash computation.
19379 Normally we prefer signed values; but hashing is special, because
19380 it's better to use unsigned division on hash table sizes so that
19381 the remainder is nonnegative. Also, size_t is the natural width
19382 for hashing into memory. The previous code used 'int', which doesn't
19383 retain enough info to hash well into very large tables.
19384 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19386 * dbusbind.c: Don't possibly lose pointer info when converting.
19387 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19388 Use XPNTR rather than XHASH, so that the high-order bits of
19389 the pointer aren't lost when converting through void *.
19391 * eval.c (Fautoload): Don't double-shift a pointer.
19393 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19395 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19397 * gnutls.c (DEF_GNUTLS_FN):
19398 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19400 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19402 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19405 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19407 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19408 New version that can reserve upto 2GB of heap space.
19410 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19412 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19414 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19416 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19417 `gnutls_certificate_set_x509_key_file'.
19419 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19421 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19422 Update dependencies.
19424 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19426 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19427 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19428 Remove unused parameter `fildes'.
19429 * process.c (read_process_output, send_process): Don't pass it.
19431 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19433 Fix previous change: the library cache is defined in w32.c.
19434 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19435 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19437 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19439 Implement dynamic loading of GnuTLS on Windows.
19441 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19442 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19443 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19446 * gnutls.c (Qgnutls_dll): Define.
19447 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19448 (gnutls_*): Declare function pointers.
19449 (init_gnutls_functions): New function to initialize function pointers.
19450 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19451 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19452 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19453 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19454 (emacs_gnutls_write, emacs_gnutls_read)
19455 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19456 (Fgnutls_available_p): New function.
19457 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19458 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19459 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19461 * image.c: Include w32.h.
19462 (Vimage_type_cache): Delete.
19463 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19464 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19465 (w32_delayed_load): Move to w32.c.
19467 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19469 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19470 (w32_delayed_load): Move from image.c. When loading a library, record
19471 its filename in the :loaded-from property of the library id.
19472 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19473 Initialize and staticpro them.
19474 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19476 * process.c: Include lisp.h before w32.h, not after.
19477 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19478 instead of gnutls_record_check_pending.
19480 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19482 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19484 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19485 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19488 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19490 * xterm.c (x_set_frame_alpha): Do not set property on anything
19491 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19493 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19495 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19497 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19499 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19500 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
19501 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

19506 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19507 (Qgnutls_bootprop_callbacks_verify): Make static.
19509 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19511 * callproc.c: Indentation fixup.
19513 * sysdep.c (wait_for_termination_1): Make static.
19514 (wait_for_termination, interruptible_wait_for_termination):
19515 Move after wait_for_termination_1.
19517 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19519 * sysdep.c (interruptible_wait_for_termination): New function
19520 which is like wait_for_termination, but allows keyboard
19523 * callproc.c (Fcall_process): Add (:file "file") as an option for
19525 (Fcall_process_region): Ditto.
19527 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19529 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19530 rather than `XVECTOR (FOO)->size'.
19532 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19533 inttypes.h, as a gnulib replacement is used if it not available in
19536 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19538 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19539 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19540 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19542 * coding.c (coding_alloc_by_realloc): Error out if destination
19543 will grow beyond MOST_POSITIVE_FIXNUM.
19544 (decode_coding_emacs_mule): Abort if there isn't enough place in
19545 charbuf for the composition carryover bytes. Reserve an extra
19546 space for up to 2 characters produced in a loop.
19547 (decode_coding_iso_2022): Abort if there isn't enough place in
19548 charbuf for the composition carryover bytes.
19550 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19552 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19553 aborting when %lld or %lll format is passed.
19554 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19555 %llo or %llx format is passed. (Bug#8545)
19557 * window.c (window_scroll_line_based): Use a marker instead of
19558 simple variables to record original value of point. (Bug#7952)
19560 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19561 produced by %s or %c overflows available buffer space. (Bug#8545)
19563 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19565 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19566 (SIZE_MAX): Move defn after all includes, as they might #define it.
19568 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19570 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19572 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19574 * keyboard.c (Qdelayed_warnings_hook): Define.
19575 (command_loop_1): Run `delayed-warnings-hook'
19576 if Vdelayed_warnings_list is non-nil.
19577 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19578 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19580 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19582 * doprnt.c (doprnt): Don't return value smaller than the buffer
19583 size if the message was truncated. (Bug#8545).
19585 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19587 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19588 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19590 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19592 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19594 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19596 * makefile.w32-in: Update dependencies.
19598 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19600 Improve `doprnt' and its usage. (Bug#8545)
19601 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19602 `format_end'. Remove support for %l as a conversion specifier.
19603 Don't use xrealloc. Improve diagnostics when the %l size modifier
19604 is used. Update the commentary.
19606 * eval.c (verror): Simplify calculation of size_t.
19608 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19611 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19613 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19616 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19618 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19619 This makes this file independent of the recent pseudovector change.
19621 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19623 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19625 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19626 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19627 Remove unused local.
19628 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19630 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19631 GCC 4.6.0 optimizes based on type-based alias analysis.
19632 For example, if b is of type struct buffer * and v of type struct
19633 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19634 != &v->size, and therefore "v->size = 1; b->size = 2; return
19635 v->size;" must therefore return 1. This assumption is incorrect
19636 for Emacs, since it type-puns struct Lisp_Vector * with many other
19637 types. To fix this problem, this patch adds a new type struct
19638 vectorlike_header that documents the constraints on layout of vectors
19639 and pseudovectors, and helps optimizing compilers not get fooled
19640 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19641 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19642 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19644 (XSETPVECTYPE): Rewrite in terms of new macro.
19645 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19646 This is a bit clearer, and further avoids the possibility of
19647 undesirable aliasing.
19648 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19649 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19650 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19651 since Lisp_Subr is a special case (no "next" field).
19652 (ASIZE): Now uses header.size rather than size.
19653 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19654 to avoid the hassle of writing XVECTOR (foo)->header.size.
19655 (struct vectorlike_header): New type.
19656 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19657 object, to help avoid aliasing.
19658 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19659 (SUBRP): Likewise, since Lisp_Subr is a special case.
19660 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19661 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19662 (struct Lisp_Hash_Table): Combine first two members into a single
19663 struct vectorlike_header member. All uses of "size" and "next" members
19664 changed to be "header.size" and "header.next".
19665 * buffer.h (struct buffer): Likewise.
19666 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19667 * frame.h (struct frame): Likewise.
19668 * process.h (struct Lisp_Process): Likewise.
19669 * termhooks.h (struct terminal): Likewise.
19670 * window.c (struct save_window_data, struct saved_window): Likewise.
19671 * window.h (struct window): Likewise.
19672 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19673 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19674 * buffer.c (init_buffer_once): Likewise.
19675 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19677 * process.c (Fformat_network_address): Use local var for size,
19680 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19682 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19683 * data.c (atof): Remove decl; no longer used or needed.
19684 (digit_to_number): Move to lread.c.
19685 (Fstring_to_number): Use new string_to_number function, to be
19686 consistent with how the Lisp reader treats infinities and NaNs.
19687 Do not assume that floating-point numbers represent EMACS_INT
19688 without losing information; this is not true on most 64-bit hosts.
19689 Avoid double-rounding errors, by insisting on integers when
19690 parsing non-base-10 numbers, as the documentation specifies.
19691 * lisp.h (string_to_number): New decl, replacing ...
19692 (isfloat_string): Remove.
19693 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19694 (read1): Do not accept +. and -. as integers; this
19695 appears to have been a coding error. Similarly, do not accept
19696 strings like +-1e0 as floating point numbers. Do not report
19697 overflow for integer overflows unless the base is not 10 which
19698 means we have no simple and reliable way to continue.
19699 Break out the floating-point parsing into a new
19700 function string_to_number, so that Fstring_to_number parses
19701 floating point numbers consistently with the Lisp reader.
19702 (digit_to_number): Move here from data.c. Make it static inline.
19703 (E_CHAR, EXP_INT): Remove, replacing with ...
19704 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19705 (string_to_number): New function, replacing isfloat_string.
19706 This function checks for valid syntax and produces the resulting
19707 Lisp float number too. Rework it so that string-to-number
19708 no longer mishandles examples like "1.0e+". Use strtoumax,
19709 so that overflow for non-base-10 numbers is reported only when
19710 there's no portable and simple way to convert to floating point.
19712 * textprop.c (set_text_properties_1): Rewrite for clarity,
19713 and to avoid GCC warning about integer overflow.
19715 * intervals.h (struct interval): Use EMACS_INT for members
19716 where EMACS_UINT might cause problems. See
19717 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19718 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19719 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19721 (offset_intervals): Tell GCC not to worry about length overflow
19722 when negating a negative length.
19724 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19725 (overrun_check_free): Likewise.
19727 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19728 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19731 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19732 (gnutls_make_error): Rename local to avoid shadowing.
19733 (gnutls_emacs_global_deinit): ifdef out; not used.
19734 (Fgnutls_boot): Use const for pointer to readonly storage.
19735 Comment out unused local. Fix pointer signedness problems.
19737 * lread.c (openp): Don't stuff size_t into an 'int'.
19738 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19739 about possible signed overflow.
19741 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19742 (GDK_KEY_g): Don't define if already defined.
19743 (xg_prepare_tooltip): Avoid pointer signedness problem.
19744 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19746 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19747 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19749 * xfns.c (Fx_window_property): Simplify a bit,
19750 to make a bit faster and to avoid GCC 4.6.0 warning.
19751 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19753 * fns.c (internal_equal): Don't assume size_t fits in int.
19755 * alloc.c (compact_small_strings): Tighten assertion a little.
19757 Replace pEd with more-general pI, and fix some printf arg casts.
19758 * lisp.h (pI): New macro, generalizing old pEd macro to other
19759 conversion specifiers. For example, use "...%"pI"d..." rather
19760 than "...%"pEd"...".
19761 (pEd): Remove. All uses replaced with similar uses of pI.
19762 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19763 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19764 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19765 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19766 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19767 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19768 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19770 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19771 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19772 * print.c (safe_debug_print, print_object): Likewise.
19773 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19775 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19776 avoiding the 0 flag, which is not portable.
19777 * process.c (Fmake_network_process): Use pI to avoid cast.
19778 * region-cache.c (pp_cache): Likewise.
19779 * xdisp.c (decode_mode_spec): Likewise.
19780 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19781 behavior on 64-bit hosts with printf arg.
19782 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19783 (x_stop_queuing_selection_requests): Likewise.
19784 (x_get_window_property): Don't truncate byte count to an 'int'
19787 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19788 here, since it parses constructs like leading '-' and spaces,
19789 which are not wanted; and it overflows with large numbers.
19790 Instead, simply match F[0-9]+, which is what is wanted anyway.
19792 * alloc.c: Remove unportable assumptions about struct layout.
19793 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19794 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19795 (allocate_vectorlike, make_pure_vector): Use the new macros,
19796 plus offsetof, to remove unportable assumptions about struct layout.
19797 These assumptions hold on all porting targets that I know of, but
19798 they are not guaranteed, they're easy to remove, and removing them
19799 makes further changes easier.
19801 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19802 This doesn't fix a bug but makes the code clearer.
19803 (string_overrun_cookie): Now const. Use initializers that
19804 don't formally overflow signed char, to avoid warnings.
19805 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19806 can cause Emacs to crash when string overrun checking is enabled.
19807 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19808 multiple of sizeof (EMACS_INT); it need not be, if
19809 alignof(EMACS_INT) < sizeof (EMACS_INT).
19810 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19812 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19814 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19816 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19818 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19819 supposed to be handshaking. (Bug#8556)
19820 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19822 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19824 * lisp.h (Qdebug): List symbol.
19825 * eval.c (Qdebug): Restore global linkage.

19827 (handle_user_signal): Break into debugger when debug-on-event
19828 matches the current signal symbol.
19830 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19832 * alloc.c (check_sblock, check_string_bytes)
19833 (check_string_free_list): Convert to standard C.
19835 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19837 * w32.c (emacs_gnutls_push): Fix typo.
19839 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19841 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19842 "cast to pointer from integer of different size".
19844 Improve doprnt and its use in verror. (Bug#8545)
19845 * doprnt.c (doprnt): Document the set of format control sequences
19846 supported by the function. Use SAFE_ALLOCA instead of always
19849 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19850 is one byte too soon. Don't use xrealloc; instead xfree and
19853 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19855 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19858 * gnutls.c: Renamed global_initialized to
19859 gnutls_global_initialized. Added internals for the
19860 :verify-hostname-error, :verify-error, and :verify-flags
19861 parameters of `gnutls-boot' and documented those parameters in the
19862 docstring. Start callback support.
19863 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19864 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19865 on error. Return error code.
19866 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19867 (emacs_gnutls_read): Likewise.
19868 (Fgnutls_boot): Return handshake error code.
19869 (emacs_gnutls_handle_error): New function.
19870 (wsaerror_to_errno): Likewise.

19875 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
19876 (emacs_gnutls_push): Likewise.
19878 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19880 * process.c (wait_reading_process_output): Check if GnuTLS
19881 buffered some data internally if no FDs are set for TLS
19884 * makefile.w32-in (OBJ2): Add gnutls.$(O).
19885 (LIBS): Link to USER_LIBS.

19907 to changes in oldXMenu/XMenu.h from 2011-04-16.
19908 (struct XMenu): Declare `help_text' `const char **'.

19925 changes in globals.h immediately force recompilation.
19926 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19927 $(CURDIR)/s/ms-w32.h.
19928 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

19931 (syms_of_character): Don't defsubr it.
19932 <char-direction-table>: Deleted.
19934 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19936 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19937 * doprnt.c: Include limits.h.
19938 (SIZE_MAX): New macro.
19939 (doprnt): Return a size_t value. 2nd arg is now size_t.
19940 Many local variables are now size_t instead of int or unsigned.
19941 Improve overflow protection. Support `l' modifier for integer
19942 conversions. Support %l conversion. Don't assume an EMACS_INT
19943 argument for integer conversions and for %c.
19945 * lisp.h (doprnt): Restore prototype.
19947 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19948 $(SRC)/character.h.
19950 * Makefile.in (base_obj): Add back doprnt.o.
19952 * deps.mk (doprnt.o): Add back prerequisites.
19953 (callint.o): Depend on character.h.
19955 * eval.c (internal_lisp_condition_case): Include the handler
19956 representation in the error message.
19957 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19958 when breaking from the loop.
19960 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19962 * callint.c (Fcall_interactively): When displaying error message
19963 about invalid control letter, pass the character's codepoint, not
19964 a pointer to its multibyte form. Improve display of the character
19965 in octal and display also its hex code.
19967 * character.c (char_string): Use %x to display the (unsigned)
19968 codepoint of an invalid character, to avoid displaying a bogus

20193 * process.c (send_process): Adjust to the new signatures of
20194 emacs_write and emacs_gnutls_write. Do not attempt to store

20537 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20538 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20539 was inaccessible from Lisp.

20561 * xdisp.c (message_enable_multibyte): Now static.
20563 Declare Lisp_Object Q* variables to be 'static' if not exported.
20564 This makes it easier for human readers (and static analyzers)
20565 to see whether these variables are used from other modules.

20579 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20581 Make Emacs functions such as Fatom 'static' by default.
20582 This makes it easier for human readers (and static analyzers)
20583 to see whether these functions can be called from other modules.
20584 DEFUN now defines a static function. To make the function external
20585 so that it can be used in other C modules, use the new macro DEFUE.

20591 Remove decls, since these functions are now static.
20592 (Funintern, Fget_internal_run_time): New decls, since these functions
20593 were already external.

20603 Mark functions with DEFUE instead of DEFUN,
20604 if they are used in other modules.
20605 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20606 decls for now-static functions.
20607 * buffer.h (Fdelete_overlay): Remove decl.

20643 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20645 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init

20659 (overrun_check_free): Protoize.
20661 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20663 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20664 since callers should never pass a negative size.
20665 Change the signature to match that of plain 'read' and 'write'; see
20666 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20667 * lisp.h: Update prototypes of emacs_write and emacs_read.
20669 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20671 * xdisp.c (redisplay_window): Don't try to determine the character
20672 position of the scroll margin if the window start point w->startp
20673 is outside the buffer's accessible region. (Bug#8468)
20675 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20677 Fix write-region and its subroutines for buffers > 2GB.
20678 * fileio.c (a_write, e_write): Modify declaration of arguments and
20679 local variables to support buffers larger than 2GB.
20680 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20682 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20683 argument, local variables, and return value.
20685 * lisp.h: Update prototypes of emacs_write and emacs_read.
20687 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20689 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20691 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20693 Fix more problems found by GCC 4.6.0's static checks.
20695 * xdisp.c (vmessage): Use a better test for character truncation.
20697 * charset.c (load_charset_map): <, not <=, for optimization,
20698 and to avoid potential problems with integer overflow.
20699 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20700 * casetab.c (set_identity, shuffle): Likewise.
20701 * editfns.c (Fformat): Likewise.
20702 * syntax.c (skip_chars): Likewise.
20704 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20705 This also lets GCC 4.6.0 generate slightly better loop code.
20707 * callint.c (Fcall_interactively): <, not <=, for optimization.
20708 (Fcall_interactively): Count the number of arguments produced,
20709 not the number of arguments given. This is simpler and lets GCC
20710 4.6.0 generate slightly better code.
20712 * ftfont.c: Distingish more carefully between FcChar8 and char.
20713 The previous code passed unsigned char * to a functions like
20714 strlen and xstrcasecmp that expect char *, which does not
20715 conform to the C standard.
20716 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20717 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20718 char * when the C standard requires it.
20720 * keyboard.c (read_char): Remove unused var.
20722 * eval.c: Port to Windows vsnprintf (Bug#8435).
20723 Include <limits.h>.
20724 (SIZE_MAX): Define if the headers do not.
20725 (verror): Do not give up if vsnprintf returns a negative count.
20726 Instead, grow the buffer. This ports to Windows vsnprintf, which
20727 does not conform to C99. Problem reported by Eli Zaretskii.
20728 Also, simplify the allocation scheme, by avoiding the need for
20729 calling realloc, and removing the ALLOCATED variable.
20731 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20733 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20734 But keep the doprint source code for now, as we might revamp it
20735 and use it again (Bug#8435).
20736 * lisp.h (doprnt): Remove.
20737 * Makefile.in (base_obj): Remove doprnt.o.
20738 * deps.mk (doprnt.o): Remove.
20740 error: Print 32- and 64-bit integers portably (Bug#8435).
20741 Without this change, on typical 64-bit hosts error ("...%d...", N)
20742 was used to print both 32- and 64-bit integers N, which relied on
20743 undefined behavior.
20744 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20745 * lisp.h (error, verror): Mark as printf-like functions.
20746 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20747 Report overflow in size calculations when allocating printf buffer.
20748 Do not truncate output string at its first null byte.
20749 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20750 Truncate the output at a character boundary, since vsnprintf does not
20752 * charset.c (check_iso_charset_parameter): Convert internal
20753 character to string before calling 'error', since %c now has the
20755 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20756 overflow when computing char to be passed to 'error'. Do not
20757 pass Lisp_Object to 'error'; pass the integer instead.
20758 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20759 formatted with plain %d.
20761 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20763 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20765 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20767 * xterm.c (x_catch_errors): Remove duplicate declaration.
20769 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20771 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20773 2011-04-10 Jim Meyering <meyering@redhat.com>
20775 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20776 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20777 return ssize_t not "int", and use size_t as the buffer length.
20778 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20779 * gnutls.h: Update declarations.
20780 * process.c (read_process_output): Use ssize_t, to match.
20781 (send_process): Likewise.
20783 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20785 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20787 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20789 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20790 Use unsigned char, to match FcChar8 type definition.
20792 * xterm.c (handle_one_xevent):
20793 * xmenu.c (create_and_show_popup_menu):
20794 * xselect.c (x_decline_selection_request)
20795 (x_reply_selection_request): Avoid type-punned deref of X events.
20797 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20799 Fix some uses of `int' instead of EMACS_INT.
20800 * search.c (string_match_1, fast_string_match)
20801 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20802 (scan_buffer, find_next_newline_no_quit)
20803 (find_before_next_newline, search_command, Freplace_match)
20804 (Fmatch_data): Make some `int' variables be EMACS_INT.
20806 * xdisp.c (display_count_lines): 3rd argument and return value now
20807 EMACS_INT. All callers changed.
20808 (pint2hrstr): Last argument is now EMACS_INT.
20810 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20811 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20812 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20826 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20827 (encode_invocation_designation): Last argument P_NCHARS is now
20829 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20830 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20832 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

20853 instead of using internal_with_output_to_temp_buffer.
20854 (Qhelp_form_show): New var.
20855 (syms_of_keyboard): Use DEFSYM macro.
20857 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20870 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20872 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20874 Fix more problems found by GCC 4.6.0's static checks.
20876 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

20880 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20882 * xdisp.c (vmessage): Mark as a printf-like function.
20884 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20888 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20889 printf-like functions.
20890 (tiff_load): Add casts to remove these marks before passing them
20891 to system-supplied API.
20893 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20895 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20896 This avoids several warnings with gcc -Wstrict-overflow.
20897 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20898 directly, rather than having caller test rule sign. This avoids
20899 some unnecessary tests.
20900 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20901 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20902 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20904 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20905 (xfont_open): Avoid unnecessary tests.
20907 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20909 * composite.h, composite.c (composition_gstring_put_cache):
20910 Use EMACS_INT, not int, for length.
20912 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20913 breaking out part of COMPOSITION_DECODE_RULE.
20914 (COMPOSITION_DECODE_RULE): Use it.
20915 * composite.c (get_composition_id): Remove unused local vars,
20916 by using the new macro.
20918 * textprop.c (set_text_properties_1): Change while to do-while,
20919 since the condition is always true at first.
20921 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20922 (interval_deletion_adjustment): Return unsigned value.
20925 * process.c (list_processes_1, create_pty, read_process_output):
20926 (exec_sentinel): Remove vars that were set but not used.
20927 (create_pty): Remove unnecessary "volatile"s.
20928 (Fnetwork_interface_info): Avoid possibility of int overflow.
20929 (read_process_output): Do adaptive read buffering even if carryover.
20930 (read_process_output): Simplify nbytes computation if buffered.

20935 (update_syntax_table): Use unsigned instead of int.
20937 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20938 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20939 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20941 * print.c (print_error_message): Avoid int overflow.
20943 * font.c (font_list_entities): Redo for clarity,
20944 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20946 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20947 (font_score): Avoid potential overflow in diff calculation.
20949 * fns.c (substring_both): Remove var that is set but not used.
20950 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20952 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20954 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20955 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20956 can always succeed if overflow has undefined behavior.
20958 * search.c (boyer_moore, wordify): Remove vars set but not used.
20959 (wordify): Omit three unnecessary tests.
20961 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20962 All callers changed. This avoids the need for an unused var.
20964 * casefiddle.c (casify_region): Remove var that is set but not used.
20966 * dired.c (file_name_completion): Remove var that is set but not used.
20968 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20970 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20971 (Finsert_file_contents): Remove unnecessary code checking fd.
20973 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20974 Check for integer overflow on size calculations.
20976 * buffer.c (Fprevious_overlay_change): Remove var that is set
20979 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20980 Remove vars that are set but not used.
20981 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20982 (timer_check_2): Mark vars as initialized.
20984 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20986 * image.c (lookup_image): Remove var that is set but not used.
20987 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20989 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20990 that are set but not used.
20992 * xfns.c (make_invisible_cursor): Don't return garbage
20993 if XCreateBitmapFromData fails (Bug#8410).
20995 * xselect.c (x_get_local_selection, x_handle_property_notify):
20996 Remove vars that are set but not used.
20998 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20999 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21001 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21002 Remove var that is set but not used.
21003 (scroll_bar_windows_size): Now size_t, not int.
21004 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21005 Check for overflow.
21007 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21008 (map_tty_color) [!defined MSDOS]: Likewise.
21010 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21012 * coding.c: Remove vars that are set but not used.
21013 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21014 All callers changed.
21015 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21016 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21017 (decode_coding_charset): Remove vars that are set but not used.
21019 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21020 that is set but not used.
21022 * print.c (print_object): Remove var that is set but not used.
21024 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21025 The gnulib version avoids calling malloc in the usual case,
21026 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21027 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21028 * filelock.c (current_lock_owner): Likewise.
21029 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21030 * sysdep.c: Include allocator.h, careadlinkat.h.
21031 (emacs_no_realloc_allocator): New static constant.
21032 (emacs_readlink): New function.
21033 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21034 ../lib/careadlinkat.h.
21036 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21038 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21039 first non-nil return value).
21041 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21043 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21044 if not defined (Bug#8403).
21046 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21048 * xdisp.c (display_count_lines): Remove parameter `start',
21049 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21050 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21051 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21053 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21054 and thereabouts. All callers changed.
21055 (get_per_char_metric): Remove parameter `f', unused since
21056 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21058 2011-04-02 Jim Meyering <meyering@redhat.com>
21060 do not dereference NULL upon failed strdup
21061 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21062 (ns_get_family): Likewise.
21064 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21066 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21068 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21070 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21073 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21075 Add lexical binding.
21077 * window.c (Ftemp_output_buffer_show): New fun.
21078 (Fsave_window_excursion):
21079 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21081 * lread.c (lisp_file_lexically_bound_p): New function.
21082 (Fload): Bind Qlexical_binding.
21083 (readevalloop): Remove `evalfun' arg.
21084 Bind Qinternal_interpreter_environment.
21085 (Feval_buffer): Bind Qlexical_binding.
21086 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21088 (syms_of_lread): Declare `lexical-binding'.
21090 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21092 * keyboard.c (eval_dyn): New fun.
21093 (menu_item_eval_property): Use it.
21095 * image.c (parse_image_spec): Use Ffunctionp.
21097 * fns.c (concat, mapcar1): Accept byte-code-functions.
21099 * eval.c (Fsetq): Handle lexical vars.
21100 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21101 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21102 (FletX, Flet): Obey lexical binding.
21103 (Fcommandp): Handle closures.
21104 (Feval): New `lexical' arg.
21105 (eval_sub): New function extracted from Feval. Use it almost
21106 everywhere where Feval was used. Look up vars in lexical env.
21108 (Ffunctionp): Move from subr.el.
21109 (Ffuncall): Handle closures.
21110 (apply_lambda): Remove `eval_flags'.
21111 (funcall_lambda): Handle closures and new byte-code-functions.
21112 (Fspecial_variable_p): New function.
21113 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21114 but without exporting it to Lisp.
21116 * doc.c (Fdocumentation, store_function_docstring):
21117 * data.c (Finteractive_form): Handle closures.
21119 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21122 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21124 (exec_byte_code): New function extracted from Fbyte_code to handle new
21125 calling convention for byte-code-functions. Add new byte-codes.
21127 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21129 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21131 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21133 * xdisp.c (redisplay_internal): Fix prototype.
21135 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21137 * xdisp.c (SCROLL_LIMIT): New macro.
21138 (try_scrolling): Use it when setting scroll_limit.
21139 Limit scrolling to 100 screen lines.
21140 (redisplay_window): Even when falling back on "recentering",
21141 position point in the window according to scroll-conservatively,
21142 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21144 (try_scrolling): When point is above the window, allow searching
21145 as far as scroll_max, or one screenful, to compute vertical
21146 distance from PT to the scroll margin position. This prevents
21147 try_scrolling from unnecessarily failing when
21148 scroll-conservatively is set to a value slightly larger than the
21149 window height. Clean up the case of PT below the margin at bottom
21150 of window: scroll_max can no longer be INT_MAX. When aggressive
21151 scrolling is in use, don't let point enter the opposite scroll
21152 margin as result of the scroll.
21153 (syms_of_xdisp) <scroll-conservatively>: Document the
21154 threshold of 100 lines for never-recentering scrolling.
21156 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21158 * dispextern.h (move_it_by_lines):
21159 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21160 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21161 (message_log_check_duplicate): Remove parameters `prev_bol' and
21162 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21163 (redisplay_internal): Remove parameter `preserve_echo_area',
21164 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21166 * indent.c (Fvertical_motion):
21167 * window.c (window_scroll_pixel_based, Frecenter):
21168 Don't pass `need_y_p' to `move_it_by_lines'.
21170 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21172 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21173 steal a few bits to be more compact.
21174 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21175 Remove unneeded casts.
21177 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21179 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21181 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21182 binding" message (bug#7967).
21184 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21186 Fix more problems found by GCC 4.6.0's static checks.
21188 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21189 Remove unused local var.
21191 * editfns.c (Fmessage_box): Remove unused local var.
21193 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21194 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21195 Omit unused local vars.
21196 * window.c (shrink_windows): Omit unused local var.
21197 * menu.c (digest_single_submenu): Omit unused local var.
21198 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21199 Omit unused local var.
21201 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21202 Don't assume string length fits in int.
21203 (keyremap_step, read_key_sequence): Use size_t for sizes.
21204 (read_key_sequence): Don't check last_real_key_start redundantly.
21206 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21207 instead of alloca (Bug#8344).
21209 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21210 (Fbacktrace_frame): Don't assume nframes fits in int.
21212 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21214 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21217 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21219 * cm.c (calccost): Turn while-do into do-while, for clarity.
21221 * keyboard.c (syms_of_keyboard): Use the same style as later
21222 in this function when indexing through an array. This also
21223 works around GCC bug 48267.
21225 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21227 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21229 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21230 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21232 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21233 This avoids undefined behavior on integer overflow, and is a bit
21234 more convenient anyway since it is compared to a size_t variable.
21236 Variadic C functions now count arguments with size_t, not int.
21237 This avoids an unnecessary limitation on 64-bit machines, which
21238 caused (substring ...) to crash on large vectors (Bug#8344).
21239 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21240 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21241 All variadic functions and their callers changed accordingly.

21248 * fns.c (concat): Likewise.
21249 * frame.c (x_set_frame_parameters): Likewise.
21250 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21251 0 if not found, not -1. All callers changed.
21253 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21254 (stack_copy_size): Now size_t, not int.
21255 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21257 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21259 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21260 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21261 All callers changed.
21263 * lisp.h (multibyte_char_to_unibyte):
21264 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21265 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21266 * character.h (CHAR_TO_BYTE8):
21267 * cmds.c (internal_self_insert):
21268 * editfns.c (general_insert_function):
21269 * keymap.c (push_key_description):
21270 * search.c (Freplace_match):
21271 * xdisp.c (message_dolog, set_message_1): All callers changed.
21273 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21275 * keyboard.c (safe_run_hook_funcall): New function.
21276 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21277 don't set the hook to nil, but remove the offending function instead.
21278 (Qcommand_hook_internal): Remove, unused.
21279 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21280 Vcommand_hook_internal.
21282 * eval.c (enum run_hooks_condition): Remove.
21283 (funcall_nil, funcall_not): New functions.
21284 (run_hook_with_args): Call each function through a `funcall' argument.
21285 Remove `cond' argument, now redundant.
21286 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21287 (Frun_hook_with_args_until_failure): Adjust accordingly.
21288 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21290 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

21460 * buffer.c (Fkill_all_local_variables):
21461 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21463 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21464 unconditionally since it does the check itself.
21466 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21468 Fix more problems found by GCC 4.5.2's static checks.
21470 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21471 the first time through the loop, since we know p0 < p1 then.
21472 This also avoids a gcc -Wstrict-overflow warning.
21474 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21475 leading to a memory leak, possible in functions like
21476 load_charset_map_from_file that can allocate an unbounded number
21477 of objects (Bug#8318).
21479 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21480 that could (at least in theory) be that large.
21482 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21483 This is less likely to overflow, and avoids undefined behavior if
21484 overflow does occur. All callers changed. Use strtoul to scan
21485 for the unsigned long integer.
21486 (pint2hrstr): Simplify and tune code slightly.
21487 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21502 * process.c (Fmake_network_process): Use socklen_t, not int,
21503 where POSIX says socklen_t is required in portable programs.
21504 This fixes a porting bug on hosts like 64-bit HP-UX, where
21505 socklen_t is wider than int (Bug#8277).
21506 (Fmake_network_process, server_accept_connection):
21507 (wait_reading_process_output, read_process_output):
21510 * process.c: Rename or move locals to avoid shadowing.

21520 Make tparam.h and terminfo.c consistent.
21521 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21522 Include tparam.h instead, since it declares them.
21523 * cm.h (PC): Remove extern decl; tparam.h now does this.
21524 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21525 * terminfo.c: Include tparam.h, to check interfaces.
21526 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21527 (tparam): Adjust signature to match interface in tparam.h;
21528 this removes some undefined behavior. Check that outstring and len
21529 are zero, which they always are with Emacs.
21530 * tparam.h (PC, BC, UP): New extern decls.
21532 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21533 (xftfont_open): Rename locals to avoid shadowing.

21551 (composition_update_it): Mark var as initialized.
21552 (find_automatic_composition): Mark vars as initialized,
21553 with a FIXME (Bug#8290).

21559 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21560 to avoid shadowing.

21572 Fix pointer signedness.
21573 (alsa_choose_format): Remove unused local var.
21574 (wav_play): Initialize a variable to 0, to prevent undefined
21575 behavior (Bug#8278).
21577 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21579 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21581 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21582 clobbering (Bug#8298).
21583 * sysdep.c (sys_subshell): Likewise.
21584 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21586 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21587 This should get cleaned up, so that child_setup has the
21588 same signature on all platforms.
21590 * callproc.c (call_process_cleanup): Now static.
21591 (relocate_fd): Rename locals to avoid shadowing.
21593 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21595 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21596 not to be necessary, and produces flickering.
21598 2011-03-20 Glenn Morris <rgm@gnu.org>
21600 * config.in: Remove file.
21602 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21653 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21655 * deps.mk (unexalpha.o): Remove; unused.

21744 Rename locals to avoid shadowing.
21745 (mark_stack): Move local variables into the #ifdef region where
21747 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

21750 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
21751 (GC_STRING_CHARS): Remove; not used.
21752 (Fmemory_limit): Cast sbrk's returned value to char *.
21754 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21755 avoids undefined behavior in theory.
21757 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21759 Use functions, not macros, for up- and down-casing (Bug#8254).
21760 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21761 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21762 to use the following functions instead of these macros.
21763 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21764 EMACS_INT, since callers assume the returned value fits in int.
21765 (upcase1): Likewise, for UPCASE_TABLE.
21766 (uppercasep, lowercasep, upcase): New static inline functions.
21767 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
21768 the race-condition problem in the old DOWNCASE.
21770 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
21771 Rename locals to avoid shadowing.
21772 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
21773 (regex_compile, re_search_2, re_match_2_internal):
21774 Remove unused local vars.
21775 (FREE_VAR): Rewrite so as not to use empty "else",
21776 which gcc can warn about.
21777 (regex_compile, re_match_2_internal): Mark locals as initialized.
21778 (RETALLOC_IF): Define only if needed.
21779 (WORDCHAR_P): Likewise. This one is never needed, but is used
21780 only in a comment talking about a compiler bug, so put inside
21781 the #if 0 of that comment.
21782 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21783 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21786 * search.c (boyer_moore): Rename locals to avoid shadowing.
21787 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

21798 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.

21809 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21810 New macros, so that the caller can use some names other than
21811 gcpro1, gcpro2, etc.
21812 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21814 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21815 argument, for consistency with GCPRO2_VAR, etc: it is now the
21816 prefix of the variable, not the variable itself. All uses
21818 * dired.c (directory_files_internal, file_name_completion):
21819 Rename locals to avoid shadowing.
21821 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21822 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21823 dired.c's scmp function, had undefined behavior.
21824 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21825 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21826 * buffer.h: ... to here, because these macros use current_buffer,
21827 and the new implementation with inline functions needs to have
21828 current_buffer in scope now, rather than later when the macros
21830 (downcase, upcase1): New static inline functions.
21831 (DOWNCASE, UPCASE1): Reimplement using these functions.
21832 This avoids undefined behavior in expressions like
21833 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21834 from race conditions in accessing the global variables
21835 case_temp1 and case_temp2.
21836 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21837 * lisp.h (case_temp1, case_temp2): Remove their decls.
21838 * character.h (ASCII_CHAR_P): Move from here ...
21839 * lisp.h: ... to here, so that the inline functions mentioned
21840 above can use them.
21842 * dired.c (directory_files_internal_unwind): Now static.
21844 * fileio.c (file_name_as_directory, directory_file_name):
21845 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21847 (file_name_as_directory): Use const pointers when appropriate.
21848 (Fexpand_file_name): Likewise. In particular, newdir might
21849 point at constant storage, so make it a const pointer.
21850 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21851 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21853 (Fset_file_times, Finsert_file_contents, auto_save_error):

21858 to avoid shadowing.
21860 * marker.c (bytepos_to_charpos): Remove; unused.
21862 * lisp.h (verify_bytepos, count_markers): New decls,
21863 so that gcc does not warn that these functions aren't declared.
21865 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21866 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21867 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21868 (copy_text): Remove unused local var.
21870 * filelock.c (within_one_second): Now static.
21871 (lock_file_1): Rename local to avoid shadowing.
21873 * buffer.c (fix_overlays_before): Mark locals as initialized.
21874 (fix_start_end_in_overlays): Likewise. This function should be
21875 simplified by using pointers-to-pointers, but that's a different
21877 (switch_to_buffer_1): Now static.
21878 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21879 (report_overlay_modification): Rename locals to avoid shadowing.
21881 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21882 Fix pointer signedness issue.
21883 (sys_subshell): Mark local as volatile if checking for lint,
21884 to suppress a gcc -Wclobbered warning that does not seem to be right.
21885 (MAXPATHLEN): Define only if needed.
21887 * process.c (serial_open, serial_configure): Move decls from here ...
21888 * systty.h: ... to here, so that they can be checked.
21890 * fns.c (get_random, seed_random): Move extern decls from here ...
21891 * lisp.h: ... to here, so that they can be checked.
21893 * sysdep.c (reset_io): Now static.
21894 (wait_for_termination_signal): Remove; unused.
21896 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21901 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21902 (describe_map_tree):
21903 Rename locals to avoid shadowing.

22054 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
