10 2013-02-27 Eli Zaretskii <eliz@gnu.org>
12 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
13 _SH_DENYRW flag, instead of emacs_open, to deny any other process
14 access to the lock file until it is written and closed.
17 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
19 * callint.c (Qcall_interactively):

29 Minor textprop integer cleanup.
30 * intervals.h, textprop.c (add_text_properties_from_list):
31 Return void, not int, since nobody uses the return value.
32 * textprop.c (validate_plist, add_properties, remove_properties)
33 (Fadd_text_properties):
34 Don't assume list length fits in int.
35 (interval_has_all_properties, interval_has_some_properties)

44 2013-02-25 Eli Zaretskii <eliz@gnu.org>
46 Implement CLASH_DETECTION for MS-Windows.
48 * filelock.c [WINDOWSNT]: Include w32.h.
49 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
50 function of that name. Up-case the macro arguments.
51 (IS_LOCK_FILE): New macro.
52 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
53 (create_lock_file): New function, with body extracted from
55 [WINDOWSNT]: Implement lock files by writing a regular file with
56 the lock information as its contents.
57 (read_lock_data): New function, on Posix platforms just calls
59 [WINDOWSNT]: Read the lock info from the file.
60 (current_lock_owner): Call read_lock_data instead of calling
61 emacs_readlinkat directly.
62 (lock_file) [WINDOWSNT]: Run the file name through
65 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
66 just check if the process by that PID exists.
68 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
69 also present, as doing so will fail to error out if the file
72 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
74 * textprop.c (Fadd_text_properties, Fremove_text_properties)
75 (Fremove_list_of_text_properties): Skip all of the intervals in
76 the region between START and END that already have resp. don't
77 have the requested properties, not just the first one. Add
78 assertions that the loop afterwards always modifies the
79 properties. (Bug#13743)
81 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
83 * callint.c (Fcall_interactively): Use the right lexical environment
84 for `interactive' specs (bug#13811).

87 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
89 Simplify data_start configuration (Bug#13783).
90 This is a followon simplification to the fix for Bug#13650.
91 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
92 (START_FILES): Remove. All uses removed.
93 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
94 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.

106 * unexaix.c, unexcoff.c: Don't include mem-limits.h.
107 * unexcoff.c (etext): New decl.
108 (make_hdr): Use DATA_START instead of start_of_data.
109 * vm-limit.c: Move most of mem-limits.h's contents here.
110 (data_start): New decl. It's OK if this is approximate,
111 so simplify-away some unnecessary exactness.
112 (POINTER): Remove; all uses removed.
113 (data_space_start): Now char *, to avoid casts.
114 (exceeds_lisp_ptr): New function, replacing the old
115 EXCEEDS_LISP_PTR macro. All uses changed.
116 (check_memory_limits): Simplify and remove casts.
117 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

125 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
127 Fix regression introduced by July 10 filelock.c patch.
128 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
129 2012-07-10 patch to this file. Reported by Eli Zaretskii in
130 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
131 and diagnosed by Andreas Schwab in
132 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
134 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
136 Assume C89 or better.
137 * ralloc.c (SIZE, POINTER, NIL):
138 * vm-limit.c (POINTER):
139 Remove, replacing all uses with C89 equivalents. These old
140 symbols were present only for porting to pre-C89 platforms.
142 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
144 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
145 This avoids warning messages reported as part of Bug#13546.
147 2013-02-21 Ken Brown <kbrown@cornell.edu>
149 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
151 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
153 * sheap.c (report_sheap_usage): Prefer message1_nolog.
155 * keyboard.c (Qcommand_execute): New var.
156 (command_loop_1, read_char): Use it.
157 (Fcommand_execute): Remove, replace by an Elisp implementation.
158 (syms_of_keyboard): Adjust accordingly.
160 2013-02-19 Daniel Colascione <dancol@dancol.org>
162 * sheap.c (report_sheap_usage): Use message, not message1, so
163 that we don't try to create a buffer while we're in the middle
164 of dumping Emacs. Explain why.
166 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
167 * search.c (find_newline): Return byte position in bytepos.
169 (find_next_newline_no_quit, find_before_next_newline):
170 Add bytepos argument.
171 * lisp.h (find_newline, find_next_newline_no_quit)
172 (find_before_next_newline): Adjust prototypes.
173 * bidi.c (bidi_find_paragraph_start):
174 * editfns.c (Fconstrain_to_field, Fline_end_position):

177 (get_visually_first_element, move_it_vertically_backward):
178 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
180 2013-02-19 Eli Zaretskii <eliz@gnu.org>
182 * w32proc.c (new_child): Avoid leaking handles if the subprocess
183 resources were not orderly released.
185 2013-02-17 Eli Zaretskii <eliz@gnu.org>
187 * xdisp.c (x_draw_vertical_border): For a window that is neither
188 the leftmost nor the rightmost, redraw both the left and the right
189 vertical borders. (Bug#13723)
191 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
193 * xml.c (init_libxml2_functions):
194 * sound.c (sound_warning):
195 * sheap.c (report_sheap_usage):
196 * process.c (wait_reading_process_output):

200 * editfns.c (Fmessage, Fmessage_box):
201 * callint.c (Fcall_interactively):
202 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
204 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
206 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
207 * frame.c (syms_of_frame): ... to here.

214 unconditionally. (Bug#9066)
216 * w32.c (set_errno): Reset h_errno and don't set it to any other
217 value. Set errno instead.
218 (check_errno): Reset h_errno.
219 (sys_socket, socket_to_fd, sys_bind, sys_connect)
220 (sys_gethostname, sys_getservbyname, sys_getpeername)
221 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
222 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
224 (sys_gethostbyname): Set h_errno only errors detected.
226 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
228 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
230 2013-02-15 Eli Zaretskii <eliz@gnu.org>
232 * keyboard.c (read_char): Fix calculation of auto-save time out
233 when auto-save-timeout is less than 4. (Bug#13720)
235 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

241 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
242 make sure errno is set to an appropriate value. (Bug#13546)
243 (socket_to_fd): Add assertion against indexing fd_info[] with a
244 value that is out of bounds.
245 (sys_accept): If fd is negative, do not set up the child_process
246 structure for reading.
248 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
250 * composite.c (fill_gstring_header): Remove useless prototype.

257 (get_overlay_arrow_glyph_row, display_mode_element):
258 (decode_mode_spec_coding, message3):
259 * xfaces.c (face_at_string_position): Use bool for booleans.
262 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
264 Fix AIX port (Bug#13650).
265 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
266 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
267 was #undeffed earlier, so it cannot be used as a macro here.
268 Use the constant and not the macro.
270 2013-02-15 Eli Zaretskii <eliz@gnu.org>
272 * w32proc.c (new_child): If no vacant slots are found in
273 child_procs[], make another pass looking for slots whose process
274 has exited or died. (Bug#13546)
276 * w32.c (sys_pipe): When failing due to file descriptors above
277 MAXDESC, set errno to EMFILE.
278 (_sys_read_ahead): Update cp->status when failing to read serial
279 communications input, so that the status doesn't stay at
280 STATUS_READ_IN_PROGRESS. (Bug#13546)
282 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
284 * gtkutil.c (tb_size_cb): New function.
285 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
287 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
289 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
292 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
294 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
296 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
298 * font.c (font_range): Add pos_byte argument. Adjust comment
300 * font.h (font_range): Adjust prototype.
301 * composite.c (autocmp_chars): Pass byte position to font_range.
302 Break long line. Remove useless prototype and format comment.
304 2013-02-13 Glenn Morris <rgm@gnu.org>
306 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
308 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
310 Improve AIX port some more (Bug#13650).
311 With this, it should be as good as it was in 23.3, though it's
312 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
313 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
314 * unexaix.c (start_of_text): Remove.
315 (_data, _text): Declare as char[], not int, as AIX manual suggests.
316 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
317 (orig_load_scnptr, orig_data_scnptr):
318 Now off_t, not long, since they are file offsets.
319 (make_hdr): Use _data, not start_of_data ().
320 This is the key part of the fix.
321 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
322 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
324 * pre-crt0.c (data_start): Initialize to 1.
325 This ports to compilers that optimize the external declaration
326 'int x = 0;' as if it were 'int x;' to shrink the executable.
328 Improve AIX port (Bug#13650).
329 This doesn't fix the bug, but it makes progress: Emacs builds now.
330 * unexaix.c: Include inttypes.h, stdarg.h.
331 (report_error, report_error_1): Mark as _Noreturn.
332 (report_error): Don't report the wrong errno.
333 (report_error_1): Now varargs. All callers changed.
334 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
335 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
336 (write_ptr): Use %p to print address rather than %lx and a cast
337 to unsigned long. Grow buffer a bit, to be safer.
339 2013-02-13 Eli Zaretskii <eliz@gnu.org>
341 * bidi.c (bidi_resolve_neutral): After finding the next
342 non-neutral character, accept NEUTRAL_ON type as well, because
343 directional control characters, such as LRE and RLE, have their
344 type converted to that by bidi_resolve_weak. This avoids aborts
345 when LRE/RLE follows a run of neutrals.
346 (bidi_move_to_visually_next): Assert that return value of
347 bidi_peek_at_next_level is non-negative. Negative values will
350 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
352 Minor getenv-related fixes.
353 * callproc.c (Fcall_process_region) [!DOS_NT]:
354 Avoid unnecessary duplicate call to getenv.
355 * callproc.c (init_callproc):
356 * dispnew.c (init_display):
357 * sysdep.c (sys_subshell):
358 Omit unnecessary cast of getenv or egetenv.
360 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
362 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
365 2013-02-12 Eli Zaretskii <eliz@gnu.org>
367 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
369 (display_line): Set w->region_showing to the value of
370 it->region_beg_charpos, not to -1. This fixes redisplay
371 optimization when cursor is moved up after M->. (Bug#13623)
373 (try_scrolling): Scroll text up more if point is too close to ZV
374 and inside the scroll margin. This makes sure point is moved
375 outside the scroll margin in these cases.
377 * window.h (struct window): region_showing can no longer be
380 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
382 Tune by using memchr and memrchr.
383 * doc.c (Fsnarf_documentation):
384 * fileio.c (Fsubstitute_in_file_name):
385 * search.c (find_newline, scan_newline):
386 * xdisp.c (pos_visible_p, display_count_lines):
387 Use memchr and memrchr rather than scanning byte-by-byte.
388 * search.c (find_newline): Rename from scan_buffer.
389 Omit first arg TARGET, as it's always '\n'. All callers changed.
391 Clean up read_key_sequence a tiny bit more.
392 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
393 (read_key_sequence): Remove unused locals.
395 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
397 Clean up read_key_sequence a bit; reread active keymaps after first event.
398 * keyboard.c (read_char, read_char_x_menu_prompt)
399 (read_char_minibuf_menu_prompt):
400 Replace nmaps+maps with a single `map' arg.
401 (follow_key): Operate on a single map.
402 (active_maps): New function.
403 (test_undefined): Also return true for nil bindings.
404 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
405 a single (composed) keymap. Remember `first_event' to choose the right
406 set of active keymaps. Recompute the set of keymaps after receiving
407 the first event. Remove GOBBLE_FIRST_EVENT.
408 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
409 * keyboard.h (read_char): Update declaration.
410 * lread.c (read_filtered_event): Adjust call to read_char.
412 2013-02-11 Eli Zaretskii <eliz@gnu.org>
414 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
415 Don't use the limitation on backwards movement when lines are truncated
416 in the window. (Bug#13675)
418 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
420 * marker.c (set_marker_internal): If desired position is passed
421 as a marker, avoid call to buf_charpos_to_bytepos.
422 * window.c (Fset_window_point): Omit redundant type checking.
423 (Fset_window_start): Likewise. Format comment.
424 (window_scroll_pixel_based): Use set_marker_restricted_both
425 with character and byte positions obtained from an iterator.
426 (Fset_window_configuration): Use set_marker_restricted_both.
427 * xdisp.c (message_dolog): Likewise.
429 2013-02-10 Eli Zaretskii <eliz@gnu.org>
431 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
432 When text lines are longer than window's screen lines, don't move back
433 too far. This speeds up some redisplay operations. (Bug#13675)
435 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
437 * syntax.c (scan_sexps_forward): Fix byte position calculation
438 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
440 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
442 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
445 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
447 Minor hashing refactoring.
448 * fns.c (SXHASH_REDUCE): Move to lisp.h.
449 (sxhash_float): Return EMACS_UINT, for consistency with the other
451 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
452 non-static inline function and therefore can't use static vars.
453 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
454 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
455 with the other hash functions.
457 2013-02-09 Eli Zaretskii <eliz@gnu.org>
459 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
460 XXXXXX part of the temporary file pattern is not downcased even
461 when w32-downcase-file-names is non-nil. (Bug#13661)
463 * xdisp.c (decode_mode_spec): Remove handling of %t.
465 * msdos.c (careadlinkatcwd): Remove.
467 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
469 * lread.c (skip_dyn_bytes): New function (bug#12598).
470 (read1): Use it. Use getc instead of READCHAR to read bytes.
471 (load_each_byte): Remove. Update users.
473 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
475 * search.c (scan_buffer): Calculate end byte position just once.
476 (scan_newline): Do not recalculate start_byte.
477 (search_command): Use eassert.
478 * syntax.c (struct lisp_parse_state): New member location_byte.
479 (scan_sexps_forward): Record from_byte and avoid redundant
480 character to byte position calculation ...

498 * window.c (Fcurrent_window_configuration):
499 * xfaces.c (Fx_family_fonts):
500 * xselect.c (selection_data_to_lisp_data): Use it.
502 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
504 * coding.c (Fdefine_coding_system_internal): Use AREF where
505 argument is known to be a vector.
506 * fns.c (Flocale_info): Likewise for ASET.
507 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
508 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
510 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
512 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
515 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
516 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
517 updateCollectionBehaviour.
519 * nsterm.m (NEW_STYLE_FS): Remove.
520 (ns_last_use_native_fullscreen): New variable.
521 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
522 (x_set_window_size): Do not take title bar and tool bar into account
523 if isFullscreen returns YES.
524 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
525 (check_native_fs): New function.
526 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
527 (ns_term_init): Remove NEW_STYLE_FS.
528 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
529 and tool bar if isFullscreen returns NO.
530 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
531 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
533 (window:willUseFullScreenPresentationOptions:): New method.
534 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
535 Hide toolbar if not enabled (Bug#13444).
536 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
537 Restore tool bar if enabled, hide it otherwise (Bug#13444).
538 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
539 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
540 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
541 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
542 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
543 (syms_of_nsterm): Add ns-use-native-fullscreen.
545 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
547 * fileio.c (Qchoose_write_coding_system): Now static.
549 2013-02-04 Eli Zaretskii <eliz@gnu.org>
551 * xdisp.c (window_buffer_changed): region_showing can be negative,
552 which still means region is being displayed.
553 (redisplay_internal): Resurrect code that forced redisplay of the
554 whole window when showing region and the mark has changed.
555 Record the new mark position to allow redisplay optimizations.
556 (display_line): If it->region_beg_charpos is non-zero, set the
557 window's region_showing member to -1. (Bug#13623) (Bug#13626)
559 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
560 not bitfield of 1 bit.
562 2013-02-03 Daniel Colascione <dancol@dancol.org>
564 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
565 daemon mode works on cygw32 when Emacs is installed and not just
568 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
570 Avoid file time stamp bug on MS-Windows (Bug#13149).
571 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
572 as FAT32 doesn't update time stamps when truncating them.
573 Also, check that a file time stamp is not a multiple of 100 ns;
574 this should catch all instances of the problem on MS-Windows,
575 as its native file system resolution is 100 ns or worse, and
576 checking for a non-multiple of 100 ns should impose only a small
577 overhead on systems with ns resolution.
579 2013-02-02 Eli Zaretskii <eliz@gnu.org>
581 Avoid encoding file names on MS-Windows when they need to be run
582 through dostounix_filename.
583 * w32.c (normalize_filename): Accept an additional argument
584 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
585 downcase it even if w32-downcase-file-names is non-nil.
586 (dostounix_filename): Accept an additional argument MULTIBYTE and
587 pass it to normalize_filename.
588 (emacs_root_dir): Adjust.
590 * msdos.h (dostounix_filename): Adjust prototype.
592 * w32.h (dostounix_filename): Adjust prototype.
594 * msdos.c (dostounix_filename): Accept an additional argument and
596 (init_environment): Adjust callers of dostounix_filename.
598 * fileio.c (Ffile_name_directory, file_name_as_directory)
599 (directory_file_name, Fexpand_file_name)
600 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
602 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
604 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
605 variables, as egetenv is case-insensitive for DOS_NT.
607 * dired.c (file_name_completion): Don't call Fdirectory_file_name
608 with an encoded file name.
610 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
611 Adjust calls to dostounix_filename.
613 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
615 * unexw32.c (unexec): Adjust call to dostounix_filename.
617 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
619 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
622 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
625 * callproc.c (Fcall_process): Make sure program name in PATH and
626 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
627 is passed to exec/spawnve, which fails unless the file-name
630 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
631 even if w32-quote-process-args is nil.
633 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
635 Fix timestamp bug when write-region appends nothing (Bug#13149).
636 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
637 the file's time stamp doesn't change if Emacs happens to write nothing
638 to the file, and on a buggy file system this could cause Emacs to
639 incorrectly infer that the file system doesn't have the bug.
640 Avoid this problem by inhibiting the inference in this case.
642 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
644 * window.h (struct window): Convert base_line_number, base_line_pos
645 and column_number_displayed members from Lisp_Object to ptrdiff_t.
646 Convert region_showing member from Lisp_Object to bitfield.
647 Remove sequence_number member. Adjust comments.
648 * window.c (sequence_number): Remove.
649 (make_window): Initialize column_number_displayed.
650 * print.c (print_object): Follow the printed representation of
651 frames and print window pointer to distinguish between windows.
652 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
653 * xdisp.c (wset_base_line_number, wset_base_line_pos)
654 (wset_column_number_displayed, wset_region_showing): Remove.
655 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
656 (try_scrolling, try_cursor_movement, redisplay_window)
657 (try_window_reusing_current_matrix, try_window_id, display_line)
658 (display_mode_lines, decode_mode_spec): Adjust users.
659 * .gdbinit (pwinx): Do not print sequence_number.
661 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
663 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
664 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
665 * dired.c: Include <fcntl.h>.
666 (open_directory): New function, which uses open and fdopendir
667 rather than opendir. DOS_NT platforms still use opendir, though.
668 (directory_files_internal, file_name_completion): Use it.
669 (file_attributes): New function, with most of the old Ffile_attributes.
670 (directory_files_internal, Ffile_attributes): Use it.
671 (file_attributes, file_name_completion_stat): First arg is now fd,
672 not dir name. All uses changed. Use fstatat rather than lstat +
674 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
675 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
676 (emacs_readlinkat): New function, with much of the old
677 Ffile_symlink_p, but with an fd argument for speed.
678 It uses readlinkat rather than careadlinkatcwd, so that it
679 need not assume the working directory.
680 (Ffile_symlink_p): Use it.
681 * filelock.c (current_lock_owner): Use emacs_readlinkat
682 rather than emacs_readlink.
683 * lisp.h (emacs_readlinkat): New decl.
684 (READLINK_BUFSIZE, emacs_readlink): Remove.
685 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
686 (emacs_norealloc_allocator, emacs_readlink): Remove.
687 This stuff is moved to fileio.c.
688 * w32.c (fstatat, readlinkat): New functions.
689 (careadlinkat): Don't check that fd == AT_FDCWD.
690 (careadlinkatcwd): Remove; no longer needed.
692 2013-01-31 Glenn Morris <rgm@gnu.org>
694 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
695 (Fwrite_region): Update for new choose_write_coding_system args.
696 Move the last piece of choose_write_coding_system here. (Bug#13522)
697 (syms_of_fileio): Add choose-write-coding-system.
699 2013-01-30 Eli Zaretskii <eliz@gnu.org>
701 * w32.c (sys_open): Zero out the flags for the new file descriptor.
702 (sys_close): Zero out the flags for the file descriptor before
703 closing it. (Bug#13546)
705 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
706 (logon_network_drive, stat_worker, symlink, chase_symlinks):
707 Use CharNextExA and CharPrevExA to iterate over file names encoded in
710 * w32.c (w32_get_long_filename, init_environment, readlink):
711 Support file names encoded in DBCS codepages.
712 (readlink): Use the current file-name-coding-system, not the ANSI
713 codepage, to decode and handle targets of symlinks.
715 2013-01-28 Eli Zaretskii <eliz@gnu.org>
717 * w32.c (opendir): Now accepts a 'const char *'.
719 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
721 Remove obsolete redisplay code. See the discussion at
722 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
723 * dispnew.c (preemption_period, preemption_next_check): Remove.
724 (Vredisplay_preemption_period): Likewise.
725 (update_frame, update_single_window, update_window, update_frame_1):
726 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
727 used, following the 2012-06-22 change.
729 2013-01-25 Eli Zaretskii <eliz@gnu.org>
731 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
733 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
735 * font.c (num_fonts): Remove the leftover from old
736 debugging code. Adjust comment style here and there.
737 * insdel.c (insert_1): Remove.
738 * lisp.h (insert_1): Remove prototype.
739 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
741 2013-01-25 Eli Zaretskii <eliz@gnu.org>
743 * w32.c (max_filename_mbslen): New function.
744 (normalize_filename, readdir): Use it to detect locales where ANSI
745 encoding of file names uses a double-byte character set (DBCS).
746 If a DBCS encoding is used, advance by characters using
747 CharNextExA, instead of incrementing a 'char *' pointer.
748 Use _mbslwr instead of _strlwr. (Bug#13515)
750 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
751 request of memory reservation to 1.7GB. (Bug#13065)
753 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
755 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
756 at check_extra_latin label. (Bug#13505)
758 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
760 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
761 Avoid redundant calls to strlen.
763 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
765 Drop async_visible and async_iconified fields of struct frame.
766 This is possible because async input is gone; for details, see
767 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
768 * frame.h (struct frame): Remove async_visible and async_iconified
769 members, convert garbaged to unsigned bitfield. Adjust comments.
770 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
771 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
772 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
773 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
774 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
776 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
777 properly. Likewise for obscured.
779 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
782 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
784 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
786 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
787 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
789 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
791 * xdisp.c (message2, message2_nolog): Remove functions.
792 (message3, message3_nolog): Extract nbytes and multibyteness directly
793 from the string. Change all callers.
794 (message3_nolog): Don't set message_enable_multibyte since set_message
795 will reset it anyway.
796 (message1, message1_nolog): Use message3.
797 (vmessage): Use a stack allocated buffer rather than f->message_buf.
798 (with_echo_area_buffer): Remove last two arguments. Update all callers.
799 (set_message): Drop all but the second arg, which has to be a string.
800 (set_message_1): Simplify now that we know that a1 is NULL and the
801 second arg is a string.
802 * frame.h (struct frame): Remove `message_buf' field.
803 Use glyphs_initialized_p instead.
804 (FRAME_MESSAGE_BUF): Remove macro.
805 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
806 * lisp.h (message2, message2_nolog): Remove declarations.
807 (message3, message3_nolog): Update declarations.
808 * keyboard.c (read_char_minibuf_menu_text)
809 (read_char_minibuf_menu_width): Remove vars.
810 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
811 to correctly handle multibyte strings.
812 * frame.c (delete_frame): Don't free message_buf any more.
813 * editfns.c (message_text, message_length): Remove vars.
814 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
815 * fileio.c (auto_save_error): Use message3 instead of message2.
816 * dispnew.c (adjust_frame_message_buffer): Remove function.
818 2013-01-23 Eli Zaretskii <eliz@gnu.org>
820 * w32term.c (w32fullscreen_hook): Account correctly for the screen
821 real estate used for the tool bar and the menu bar.
823 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
825 * insdel.c (prepare_to_modify_buffer): Force redisplay if
826 hidden buffer is prepared to modification (Bug#13164).
828 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
830 * window.h (struct window): Change window_end_valid member from
831 Lisp_Object to a bitfield. Adjust comments.
832 (wset_window_end_valid): Remove.
833 * window.c (adjust_window_count): Clear window_end_valid.
834 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
835 (Fwindow_line_height, set_window_buffer, Frecenter)
836 (Fsplit_window_internal, Fdelete_other_windows_internal)
837 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
838 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
839 * xdisp.c (check_window_end, reconsider_clip_changes)
840 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
841 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
842 (find_first_unchanged_at_end_row, try_window_id): Likewise.
844 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
846 * xdisp.c (mark_window_display_accurate): Simplify the loop
847 assuming that the only one of vchild, hchild or buffer window
848 slots is non-nil. Call mark_window_display_accurate_1 for
849 the leaf windows only.
850 (mark_window_display_accurate_1): Always assume leaf window.
853 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
855 * emacs.c (Qkill_emacs_hook): Now static.
857 * fileio.c (Finsert_file_contents): Simplify.
858 Remove unnecessary assignments and tests.
860 2013-01-21 Eli Zaretskii <eliz@gnu.org>
862 * w32.c (acl_set_file): Don't test for errors unless
863 set_file_security returns FALSE. Avoids spurious errors when
866 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
868 * fileio.c (Finsert_file_contents): Revert code introduced at
869 2013-01-18 in favor of the simpler and generally better fix.
870 Save stack space by removing 'buffer' and reusing 'read_buf'
873 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
875 * lisp.h (eabs): Define unconditionally (Bug#13419).
876 The old "#if !defined (eabs)" was an unnecessary revenant of back
877 when this macro was called "abs". Document 'eabs' better.
879 2013-01-19 Glenn Morris <rgm@gnu.org>
881 * fns.c (Frandom): Doc fix.
883 2013-01-19 Eli Zaretskii <eliz@gnu.org>
885 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
886 segfault when there are lots of overlays.
888 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
889 when there are lots of overlays.
890 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
891 for the details and a way to reproduce.
893 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
895 * fileio.c: Use O_APPEND to append.
896 This corresponds better to the natural interpretation of "append",
897 and avoids the need to open the output file twice, or to invoke
898 lseek when APPEND is neither nil nor a number.
899 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
900 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
901 file possibly twice, and lseeking to its end; this avoids the
902 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
903 at the same time: the combination is never needed and apparently
904 it doesn't work with DOS_NT.
906 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
907 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
909 Allow floating-point file offsets.
910 Problem reported by Vitalie Spinu in
911 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
912 * fileio.c (emacs_lseek): Remove.
913 (file_offset): New function.
914 (Finsert_file_contents, Fwrite_region): Use it.
916 2013-01-19 Chong Yidong <cyd@gnu.org>
918 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
919 aborting on Fsignal (Bug#13289).
921 2013-01-19 Eli Zaretskii <eliz@gnu.org>
923 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
924 set_file_security as failure due to insufficient privileges.
925 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
926 (fstat): Return owner and group like 'stat' and 'lstat' do.
928 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
930 Work around bug in CIFS and vboxsf file systems (Bug#13149).
931 The bug was observed on Ubuntu operating inside a virtual machine,
932 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
933 The workaround introduces a race condition on non-buggy hosts,
934 but it's an unlikely race and anyway there's a nearly identical
935 nearby race that can't be fixed.
936 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
938 (Fwrite_region): Test for file system time stamp bug.
939 (init_fileio): New function.
940 * lisp.h (init_fileio): Declare it.
941 * emacs.c (main): Call it.
943 * fileio.c (Finsert_file_contents): Simplify new diagnostic
944 and make it more consistent with other stat-failure diagnostics.
946 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
948 Fix crash when inserting data from non-regular files.
949 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
950 for the error description produced by valgrind.
951 * fileio.c (read_non_regular): Rename to read_contents.
952 Free Lisp_Save_Value object used to pass parameters.
953 (read_non_regular_quit): Rename to read_contents_quit.
954 (Finsert_file_contents): Redesign internal file reading loop to adjust
955 gap and end positions after each read and so help make_gap to work
956 properly. Do not signal an I/O error too early and so do not leave
957 not yet decoded characters in a buffer, which was the reason of

1420 return success. This fixes problems for users backing up their
1421 own files without having the necessary privileges for setting
1422 security descriptors.
1424 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1426 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1427 after WaitForSingleObject returns normally. This expedites reader
1428 thread shutdown when delete_child triggers it.
1429 (reap_subprocess): More accurate commentary for why we call
1430 delete_child only when cp->fd is negative.
1432 * w32.c (sys_close): Do not call delete_child on a subprocess
1433 whose handle is not yet closed. Instead, set its file descriptor
1434 to a negative value, so that reap_subprocess will call
1435 delete_child on that subprocess when its SIGCHLD arrives.
1436 This avoids closing handles used for communications between sys_select
1437 and reader_thread, which doesn't give sys_select a chance to
1438 notice that the process exited and invoke the SIGCHLD handler for
1441 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1443 * nsfns.m (Fns_do_applescript): Run event loop until script has
1444 been executed (Bug#12969).
1445 (ns_run_ascript): Chech as_script for nil, set to nil after
1448 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1450 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1452 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1454 * w32term.c (w32fullscreen_hook): New function.
1455 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1457 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1459 * fileio.c (Finsert_file_contents): Doc fix.
1461 * w32proc.c (new_child, delete_child, find_child_pid): For a
1462 subprocess, consider its slot being in use as long as its process
1463 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1464 slot when a new process is started immediately after killing
1465 another one, without waiting enough time for the first process to
1466 be reaped and resources allocated for it be orderly freed.
1468 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1470 2012-12-21 Chong Yidong <cyd@gnu.org>
1472 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1474 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1476 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1478 * w32.c (get_name_and_id): Always pass NULL as the first argument
1479 of lookup_account_sid. Avoids crashes with UNC file names that
1480 refer to DFS domains, not to specific machine names. (Bug#12621)
1481 Remove now unused argument FNAME; all callers changed.
1482 (get_file_owner_and_group): Remove now unused argument FNAME; all
1485 2012-12-21 Chong Yidong <cyd@gnu.org>
1487 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1488 error for invalid chars, don't check for a nil return value.
1490 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1492 Avoid calls to CHAR_TO_BYTE if byte position is known.
1493 * editfns.c (make_buffer_string_both): Use move_gap_both.
1494 (Fbuffer_string): Use make_buffer_string_both.
1495 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1497 (buf_bytepos_to_charpos): Likewise.
1498 (charpos_to_bytepos): Remove.
1499 * fileio.c (Finsert_file_contents): Use move_gap_both.
1500 * search.c (Freplace_match): Likewise.
1501 * process.c (process_send_region): Likewise. Use convenient
1502 names for byte positions.
1503 * lisp.h (charpos_to_bytepos): Remove prototype.
1504 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1505 * insdel.c (move_gap): Likewise.

1513 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1514 (redisplay_internal): Don't bother selecting the frame to get the
1515 proper value of frame-local variables (bug#13225).
1517 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1519 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1520 Rename 4th argument since it may be buffer or string. Adjust comment.
1521 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1523 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1525 * coding.c (Fdetect_coding_region): Do not check start and end with
1526 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1527 (code_convert_region): Likewise.
1529 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1531 * w32.c (acl_get_file, acl_set_file): Run the file name through
1532 map_w32_filename, and resolve any symlinks in the file name, like
1534 (acl_set_file): Call revert_to_self, if any privileges were

1540 ($(BLD)/w32.$(O)): Update dependencies.
1542 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1544 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1545 propagate redisplay's scrolling (if any) to the right window.
1546 (redisplay_internal): Use ensure_selected_frame.
1547 (display_mode_lines): Complete last fix.
1548 * window.c (select_window_1): New func, extracted from select_window.
1549 (select_window): Use it.
1550 * window.h (select_window_1): Declare.
1552 2012-12-17 Eli Zaretskii <eliz@gnu.org>

1576 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1578 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1579 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1580 for some of that bug's symptoms can now cause Emacs to abort.
1581 Remove the workaround.
1582 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1583 The bug that caused SIGCHLD to get lost has been fixed, and the
1584 workaround for it can now cause Emacs to abort.
1586 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1588 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1589 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1590 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1592 2012-12-16 Romain Francoise <romain@orebokech.com>
1594 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1595 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1596 and copy ACL entries of file in addition to SELinux context if set.
1597 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1599 * Makefile.in (LIBACL_LIBS): New macro.

1614 * w32proc.c (new_child): Initialize input_file and
1615 pending_deletion members of the child.
1616 (delete_child): Delete the child's temporary input file, if any,
1617 that is pending deletion.
1618 (register_child): First argument is now pid_t.
1619 (record_infile, record_pending_deletion): New functions.
1620 (reap_subprocess): Fix a typo in DebPrint string.
1621 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1623 * fileio.c (internal_delete_file): Return an int again: non-zero
1624 if delete-file succeeds, zero otherwise.
1626 * lisp.h (internal_delete_file): Adjust prototype.
1628 * callproc.c (Fcall_process): Don't overwrite infile with result
1630 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1631 asynchronous subprocess, record the name of the input file name,
1633 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1634 delete the file, record it as pending deletion when the subprocess
1637 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1639 * editfns.c [HAVE_PWD_H]: Include grp.h.
1641 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

1645 Fix permissions bugs with setgid directories etc. (Bug#13125)
1646 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1647 to mark it as a placeholder. The old value was often wrong.
1648 The only user of this attribute has been changed to use
1649 file-ownership-preserved-p instead, with its new group arg.
1650 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1652 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1657 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1659 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1660 try to get accurate owner and group information from NT file
1661 security APIs. This is to make most callers of 'stat' and
1662 'lstat', which don't need that information, much faster.
1664 * dired.c (Ffile_attributes) [WINDOWSNT]:
1665 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1666 owner and group information from 'lstat'.
1668 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1670 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1671 as that confuses set-auto-coding, so insist on the head-read
1672 returning the full 1024 bytes. Let lseek compute the tail offset;
1673 less work for us. Do not ignore I/O errors when reading the tail.
1675 * xdisp.c: Minor style fixes.
1676 (init_iterator): Hoist assignment out of if-expression.
1677 (markpos_of_region): Callers now test for sign, not for -1.

1683 (init_iterator): Do not highlight the region of zero length.
1684 (redisplay_window): Check whether the region is of non-zero length.
1685 (try_cursor_movement): Allow if the region length is zero.

1688 2012-12-13 Eli Zaretskii <eliz@gnu.org>
1690 * search.c (search_buffer): Check the inverse translations of each
1691 character in pattern when the buffer being searched is unibyte.
1694 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1696 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1697 files, fixing a regression from 24.2.
1698 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1700 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1702 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1703 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1704 Remove unnecessary S_ISLNK test, as (contra the comments) this
1705 function can't copy symlinks. Improve quality of error message
1706 when attempting to copy files that are neither regular files nor

1714 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1715 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1717 2012-12-12 Daniel Colascione <dancol@dancol.org>
1719 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1720 the dumped Emacs is not a sparse file, greatly improving Cygwin
1721 "make bootstrap" performance.
1723 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1725 * inotify.c (inotify_callback): Generate an Emacs event for every
1726 incoming inotify event.
1728 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1730 * xdisp.c (handle_face_prop): Fix logic of computing
1731 it->start_of_box_run_p.
1732 (append_space_for_newline): If the glyph row is R2L, reset the
1733 iterator's end_of_box_run_p flag before prepending the space glyph.
1734 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1735 iterator's start_of_box_run_p flag before prepending the stretch.
1736 (append_glyph, produce_image_glyph, append_composite_glyph)
1737 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1738 left_box_line_p and right_box_line_p flags of the glyph for R2L
1739 glyph rows. (Bug#13011)
1741 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1746 * window.c (replace_buffer_in_windows_safely): Do nothing
1747 if buffer is not shown in a window.

1754 encoded_file_name, which is what it is.
1756 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1788 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1789 (hinst): Remove unneeded extern declaration.
1790 (_start): Remove initialization of above variables; remove
1791 initialization of hinst, as cache_system_info now does that.

1902 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1904 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1905 DWORD_PTR, for compatibility with 64-bit builds.
1907 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
1908 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
1909 (system_process_attributes): Use SIZE_T rather than DWORD, for
1910 compatibility with 64-bit builds.

1916 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1918 * indent.c (Fvertical_motion): If a display string will be
1919 displayed on the left or the right margin, don't consider it as a
1920 factor in cursor positioning. (Bug#13108)
1922 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1924 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1926 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

1931 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1933 * w32.c (unsetenv): Return 0 if the input string is too long.
1935 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1937 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1938 * alloc.c (xputenv): New function.
1939 * dbusbind.c (Fdbus_init_bus):
1941 * xterm.c (x_term_init):
1942 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

1945 (init_editfns): Initialize these two static vars.
1946 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1947 Save old TZ value on stack, if it's small.
1948 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1949 instead, use xputenv+unsetenv to set and restore TZ.
1950 (environbuf): Remove static var. All uses removed.
1951 (Fset_time_zone_rule): Do not save TZ and environ;
1952 no longer needed here.
1953 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1954 Move to inside set_time_zone_rule; they don't need file scope any more.
1955 (set_time_zone_rule): Maintain the TZ=value string separately.
1956 (syms_of_editfns): Don't initialize initial_tz;
1957 init_editfns now does it.
1958 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1959 * lisp.h (xputenv): New decl.
1961 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1963 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1965 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1967 * w32.c (unsetenv, sys_putenv): New functions.
1969 2012-12-08 Chong Yidong <cyd@gnu.org>
1971 * editfns.c (Finsert_char): Make the error message more
1972 informative (Bug#12992).
1974 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1976 Simplify get_lim_data.
1977 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1978 Remove USG and vlimit methods; no longer used these days.
1979 Add #error catchall just in case.
1981 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1982 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1983 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1984 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1985 (deleted_pid_list, Fdelete_process, create_process)
1986 (record_child_status_change, handle_child_signal, deliver_child_signal)
1987 (init_process_emacs, syms_of_process):
1988 Assume SIGCHLD is defined.
1989 (parse_signal): Remove. All uses removed.
1990 (abbr_to_signal): New static function.
1991 (Fsignal_process): Use it to convert signal names to ints.
1992 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1993 kill (getpgrp (), ...).
1994 (emacs_sigaction_init): Assume SIGCHLD is defined.
1995 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1996 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

1998 All uses replaced by 'kill' with a negative pid.
1999 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2000 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2002 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2004 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2005 This will cause a production Emacs to dump core instead of
2008 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2010 * frame.c (make_frame): Do not set window's buffer to t.
2011 * window.c (Fsplit_window_internal): Likewise. Previously it was
2012 used to indicate that the window is being set up. Now we use
2013 set_window_buffer for all new windows, so the condition in ...
2014 (Fset_window_buffer): ... is always true and can be removed.
2016 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2018 Convenient macro to check whether the buffer is hidden.
2019 * buffer.h (BUFFER_HIDDEN_P): New macro.
2020 * frame.c (make_frame): Use it. Adjust comment.
2021 * buffer.c (candidate_buffer): New function.
2022 (Fother_buffer, other_buffer_safely): Use it.
2024 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2026 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2027 if the child process is still running. Instead, exit the wait
2028 loop and return zero. (Bug#13086)
2030 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2032 * frame.h (x_char_width, x_char_height): Remove prototypes.

2043 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2045 Fix a recently-introduced delete-process race condition.
2046 * callproc.c, process.h (record_kill_process):
2047 New function, containing part of the old call_process_kill.
2048 (call_process_kill): Use it.
2049 This does not change call_process_kill's behavior.
2050 * process.c (Fdelete_process): Use record_kill_process to fix a
2051 race condition that could cause Emacs to lose track of a child.
2053 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2055 Avoid code duplication between prev_frame and next_frame.
2056 * frame.c (candidate_frame): New function. Add comment.
2057 (prev_frame, next_frame): Use it. Adjust comment.
2059 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2061 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2062 fails, signal an error instead of continuing with an empty
2064 Encode expanded temp file pattern before passing it to mkstemp or
2067 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2068 Encode the file name before passing it to dostounix_filename, in
2069 case it will downcase it (under w32-downcase-file-names).
2072 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2074 Minor call-process cleanups.
2075 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2076 at the same time as other platforms, to simplify analysis.
2077 No need for fd0_volatile since we have synch_process_fd.
2078 Avoid needless emacs_close; arg is always negative.
2080 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2082 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2085 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2087 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2088 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2089 and mouse_face_hidden members to a bitfields.
2090 * frame.h (struct frame): Remove set-but-not-used space_width member.
2091 (FRAME_SPACE_WIDTH): Remove.
2092 * nsterm.m, w32term.c, xterm.c: Adjust users.
2093 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2094 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2095 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2096 members to a bitfields.
2098 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2100 Don't let call-process be a zombie factory (Bug#12980).
2101 Fixing this bug required some cleanup of the signal-handling code.
2102 As a side effect, this change also fixes a longstanding rare race
2103 condition whereby Emacs could mistakenly kill unrelated processes,
2104 and it fixes a bug where a second C-g does not kill a recalcitrant
2105 synchronous process in GNU/Linux and similar platforms.
2106 The patch should also fix the last vestiges of Bug#9488,
2107 a bug which has mostly been fixed on the trunk by other changes.
2108 * callproc.c, process.h (synch_process_alive, synch_process_death)
2109 (synch_process_termsig, sync_process_retcode):
2110 Remove. All uses removed, to simplify analysis and so that
2111 less consing is done inside critical sections.
2112 * callproc.c (call_process_exited): Remove. All uses replaced
2113 with !synch_process_pid.
2114 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2115 These take the role of what used to be in unwind-protect arg.
2117 (block_child_signal, unblock_child_signal):
2118 New functions, to avoid races that could kill innocent-victim processes.
2119 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2120 (call_process_kill): Record killed processes as deleted, so that
2121 zombies do not clutter up the system. Do this inside a critical
2122 section, to avoid a race that would allow the clutter.
2123 (call_process_cleanup): Fix code so that the second C-g works again
2124 on common platforms such as GNU/Linux.
2125 (Fcall_process): Create the child process in a critical section,
2126 to fix a race condition. If creating an asynchronous process,
2127 record it as deleted so that zombies do not clutter up the system.
2128 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2129 light of these changes. Omit unnecessary call to emacs_close
2130 before failure, as the unwind-protect code does that.
2131 * callproc.c (call_process_cleanup):
2132 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2133 * process.c (record_deleted_pid): New function, containing
2134 code refactored out of Fdelete_process.
2135 (Fdelete_process): Use it.
2136 (process_status_retrieved): Remove. All callers changed to use
2137 child_status_change.
2138 (record_child_status_change): Remove, folding its contents into ...
2139 (handle_child_signal): ... this signal handler. Now, this
2140 function is purely a handler for SIGCHLD, and is not called after
2141 a synchronous waitpid returns; the synchronous code is moved to
2142 wait_for_termination. There is no need to worry about reaping
2143 more than one child now.
2144 * sysdep.c (get_child_status, child_status_changed): New functions.
2145 (wait_for_termination): Now takes int * status and bool
2146 interruptible arguments, too. Do not record child status change;
2147 that's now the caller's responsibility. All callers changed.
2148 Reimplement in terms of get_child_status.
2149 (wait_for_termination_1, interruptible_wait_for_termination):
2150 Remove. All callers changed to use wait_for_termination.
2151 * syswait.h: Include <stdbool.h>, for bool.
2152 (record_child_status_change, interruptible_wait_for_termination):
2154 (record_deleted_pid, child_status_changed): New decls.
2155 (wait_for_termination): Adjust to API changes noted above.
2157 * bytecode.c, lisp.h (Qbytecode): Remove.
2158 No longer needed after 2012-11-20 interactive-p changes.
2160 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2162 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2163 the scroll margin, move point outside the margin. (Bug#13055)
2165 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2167 * gtkutil.c (my_log_handler): New function.
2168 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2170 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2172 * lisp.h (modify_region): Rename to...
2173 (modify_region_1): ...new prototype.
2174 * textprop.c (modify_region): Now static. Adjust users.
2175 * insdel.c (modify_region): Rename to...
2176 (modify_region_1): ...new function to work with current buffer.
2177 Adjust comment and users. Use true and false for booleans.
2179 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2181 * alloc.c (free_save_value): New function.
2182 (safe_alloca_unwind): Use it.
2183 * lisp.h (free_save_value): New prototype.
2184 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2186 (save_excursion_restore): Adjust to match saved data structure.
2187 Use free_save_value to offload some work from GC. Drop obsolete
2190 2012-12-03 Chong Yidong <cyd@gnu.org>
2192 * fileio.c (Vauto_save_list_file_name): Doc fix.
2194 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2196 * w32fns.c: Remove prototype of atof.
2197 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2199 (file_dialog_callback): Make it UINT_PTR.
2201 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2204 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2205 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2208 2012-12-03 Glenn Morris <rgm@gnu.org>
2210 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2212 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2214 Fix xpalloc confusion after memory is exhausted.
2215 * alloc.c (xpalloc): Comment fix.
2216 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2217 and signals an error, do not clear charset_table_size, as
2218 charset_table is still valid.
2219 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2221 Use execve to avoid need to munge environ (Bug#13054).
2222 * callproc.c (Fcall_process):
2223 * process.c (create_process):
2224 Don't save and restore environ; no longer needed.
2225 * callproc.c (child_setup):
2226 Use execve, not execvp, to preserve environ.
2228 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2230 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2232 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2234 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2235 display for sliced images (Bug#10500).
2237 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2239 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2241 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2242 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2244 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2246 * xdisp.c (window_outdated): Remove eassert since it hits
2247 some suspicious corner cases (see Bug#13007 and Bug#13012).
2248 (mode_line_update_needed): New function.
2249 (redisplay_internal, redisplay_window): Use it.
2250 (ensure_selected_frame): New function.
2251 (redisplay_internal, unwind_redisplay): Use it.
2252 (redisplay_internal): Move comment about buffer_shared...
2253 (buffer_shared_and_changed): ...near to its real use.
2255 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2257 * callproc.c (Fcall_process): Don't misreport vfork failure.
2259 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2261 * callproc.c (Fcall_process): Fix vfork portability problems.
2262 Do not assume that fd[0], count, filefd, and save_environ survive
2263 vfork. Fix bug whereby wrong errno value could be reported for
2264 pipe failure. Some minor cleanups, too, as follows. Move buf and
2265 bufsize to the context where they're needed. Change new_argv to
2266 be of type char **, as this is more convenient and avoids casts.
2267 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2268 Now local constants, not macros.
2270 2012-11-18 Kenichi Handa <handa@gnu.org>
2272 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2273 for the variable "f".
2275 2012-11-13 Kenichi Handa <handa@gnu.org>
2277 * font.c (font_unparse_xlfd): Exclude special characters from the
2278 generating XLFD name.
2280 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2282 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2283 * dired.c (stat_uname, stat_gname):
2284 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2286 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2290 * fileio.c (Fcopy_file): Assume EISDIR is defined.
2291 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
2292 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
2293 * lread.c (readbyte_from_file): Assume EINTR is defined.
2294 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2295 Assume EIO and EAGAIN are defined.
2296 * unexcoff.c (write_segment): Assume EFAULT is defined.
2298 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2300 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2303 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2304 highlighting on the frame was cleared. Prevents assertion
2305 violations when repeatedly clicking on the "Top" link of the
2306 "bread-crumbs" in Info buffers.
2308 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2310 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2312 2012-11-24 Ken Brown <kbrown@cornell.edu>
2314 * keyboard.c (HAVE_MOUSE):
2315 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2316 were always defined.
2318 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2320 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2321 between bpos_covered and bpos_max. This fixes cursor display when
2322 several display strings follow each other.
2324 * .gdbinit (pgx): If the glyph's object is a string, display the
2325 pointer to string data, rather than the value of the string object
2326 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2328 * indent.c (Fvertical_motion): If the starting position is covered
2329 by a display string, return to one position before that, to avoid
2330 overshooting it inside move_it_to. (Bug#12930)
2332 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2334 * frame.h (struct frame): Remove display_preempted member

2337 * w32menu.c (pending_menu_activation): Remove since not
2339 (set_frame_menubar): Adjust user.
2340 * w32term.h (struct x_output): Drop outdated #if 0 code.
2341 (struct w32_output): Use bitfields for explicit_parent,
2342 asked_for_visible and menubar_active members.
2343 Drop unused pending_menu_activation member.
2344 * xterm.h (struct x_output): Drop outdated #if 0 code.
2345 Use bitfields for explicit_parent, asked_for_visible,
2346 has_been_visible and net_wm_state_hidden_seen members.
2348 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2350 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2351 of a literal "/". (Bug#12955)
2352 (gl-stamp): Invoke fc.exe directly, not through cmd.
2354 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2356 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2357 * dired.c: Assume HAVE_DIRENT_H.
2358 (NAMLEN): Remove, replacing with ...
2359 (dirent_namelen): New function. All uses changed. Use the GNU macro
2360 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2361 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2362 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2363 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2365 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2366 * ndir.h: Rename to ../nt/inc/dirent.h.
2367 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2368 Do not include <dirent.h>; no longer needed.
2369 * w32.c: Include <dirent.h> rather than "ndir.h".
2371 2012-11-23 Chong Yidong <cyd@gnu.org>
2373 * xftfont.c (xftfont_open): Remove duplicate assignment.
2375 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2377 * alloc.c (Fgarbage_collect): Unblock input after clearing
2378 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2379 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2380 * msdos.c (IT_frame_up_to_date): Use it here...
2381 * w32term.c (w32_frame_up_to_date): ...here...
2382 * xterm.c (XTframe_up_to_date): ...and here...
2383 * nsterm.m (ns_frame_up_to_date): ...but not here.
2384 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2386 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2387 Do not check whether GC is in progress.
2389 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2391 * xdisp.c (window_buffer_changed): New function.
2392 (update_menu_bar, update_tool_bar): Use it to
2393 simplify large 'if' statements.
2394 (redisplay_internal): Generalize commonly used
2395 'tail' and 'frame' local variables.
2397 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2399 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2400 with Windows system header.
2402 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2404 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2405 * alloc.c: Assume unistd.h exists.
2406 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2407 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2408 (getwd) [USG]: Remove; no longer needed.
2409 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2410 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2411 * w32.h (getcwd): Remove decl.
2413 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2415 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2416 Make it set selected_window as well.
2417 (update_tool_bar): Use it.
2419 2012-11-21 Ken Brown <kbrown@cornell.edu>
2421 * emacs.c (main): Set the G_SLICE environment variable for all
2422 Cygwin builds, not just GTK builds. See
2423 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2425 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2427 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2428 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2429 Define for the MSVC compiler.
2431 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2433 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2434 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2435 dostounix_filename. Prevents crashes down the road, because
2436 dostounix_filename assumes it gets a unibyte string.
2437 Reported by Michel de Ruiter <michel@sentient.nl>, see
2438 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2440 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

2444 * lread.c (init_obarray): Set `function' fields to Qnil.
2445 * eval.c (Fcommandp): Ignore Qunbound.
2446 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2447 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2448 Test NILP rather than Qunbound.
2449 (Ffmakunbound): Set to Qnil.
2450 (Fsymbol_function): Never signal an error.
2451 (Finteractive_form): Ignore Qunbound.
2453 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2455 * eval.c (interactive_p): Remove no-longer-used decl.
2457 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2459 * xdisp.c (buffer_shared): Adjust comment.
2460 (buffer_shared_and_changed): New function.
2461 (prepare_menu_bars, redisplay_internal): Use it to
2462 decide whether all windows or frames should be updated.
2463 (window_outdated): New function.
2464 (text_outside_line_unchanged_p, redisplay_window): Use it.
2465 (redisplay_internal): Likewise. Fix indentation.
2467 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2469 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2470 (syms_of_eval): Remove corresponding defsubr.
2471 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2473 2012-11-19 Daniel Colascione <dancol@dancol.org>
2475 * w32fns.c (Fx_file_dialog):
2476 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2477 cygwin_convert_file_name*.
2479 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2480 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2482 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2484 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2486 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2488 * w32select.c: Include w32common.h before w32term.h, so that
2489 windows.h gets included before w32term.h uses some of its
2490 features, see below.
2492 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2494 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2496 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2498 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2500 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2501 (ns_select): Return at once if events are held (Bug#12834).
2503 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2505 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2506 Needed following 2012-10-20 change. (Bug#12902)
2508 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2510 * w32proc.c (waitpid): Remove unused label get_result.
2512 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2514 * makefile.w32-in (SYSWAIT_H): New macro.
2515 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2516 ($(BLD)/sysdep.$(O)): Update dependencies.
2518 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2520 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2521 * callproc.c (relocate_fd): Assume F_DUPFD.
2522 * emacs.c, term.c (O_RDWR): Remove.
2523 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2524 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2525 * nsterm.m: Assume <fcntl.h> exists.
2526 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2527 (create_pty, Fmake_network_process, server_accept_connection)
2528 (wait_reading_process_output, init_process_emacs):
2530 (wait_reading_process_output): Put in a special case for WINDOWSNT
2531 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2532 It's not clear this is needed, but it's a more-conservative change.
2533 (create_process): Assume FD_CLOEXEC.
2534 (create_process, create_pty): Assume O_NOCTTY.
2535 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2536 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2537 Omit if not DOS_NT, since F_GETFL is not defined there.
2538 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2539 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2541 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2542 lack it, since gnulib guarantees this.
2543 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2545 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2547 * w32.c (faccessat): Pretend that directories have the execute bit
2548 set. Emacs expects that, e.g., in files.el:cd-absolute.
2550 * w32proc.c (create_child): Don't clip the PID of the child
2551 process to fit into an Emacs integer, as this is no longer a
2553 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2554 reaping only the process specified by PID argument, if that is
2555 positive. Use PID instead of dead_child to know which process to
2556 reap. Wait for the child to die only if WNOHANG is not in
2558 (sys_select): Don't set dead_child.
2560 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2561 as it is no longer needed.
2563 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2565 (record_child_status_change): Remove the setting of
2566 record_at_most_one_child for the !WNOHANG case.
2568 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2570 Fix problems in ns port found by static checking.
2571 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2572 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2573 not to process group.
2574 (ns_select): Use emacs_write, not write, as that's more robust
2575 in the presence of signals.
2576 (fd_handler:): Check for read errors.
2578 2012-11-16 Glenn Morris <rgm@gnu.org>
2580 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2582 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2584 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2586 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2588 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2589 use the same value of thread handle.
2590 (start_timer_thread): If the timer thread exited (due to error),
2591 clean up by closing the two handles it used. Duplicate the caller
2592 thread's handle here, so it gets duplicated only once, when
2593 launching the timer thread. Set priority of the timer thread, not
2595 (getitimer): Don't duplicate the caller thread's handle here.
2598 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2600 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2603 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2605 Remove no-longer-used pty_max_bytes variable.
2606 * process.c (pty_max_bytes): Remove; unused.
2607 (send_process): Do not set it.
2609 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2611 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2612 Update dependencies.
2614 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2616 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2617 This follows up on the 2012-09-29 patch that removed indirection
2618 for the 'function' field. Reported by Sergey Vinokurov in
2619 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2621 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2623 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2624 different name, as the MS runtime does not have such a function,
2625 and probably never will.) All callers changed. Ignore DIRFD
2626 value if PATH is an absolute file name, to match Posix spec
2627 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2630 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2632 * xdisp.c (echo_area_display, redisplay_internal):
2633 Omit redundant check whether frame_garbaged is set.
2635 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2637 Use faccessat, not access, when checking file permissions (Bug#12632).
2638 This fixes a bug that has been present in Emacs since its creation.
2639 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2640 which must set some sort of record. (Torek's bug report was against
2641 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2642 same common flaw.) See Torek's Usenet posting
2643 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2644 Posted: Fri Apr 8 14:18:56 1983.
2645 * Makefile.in (LIB_EACCESS): New macro.
2647 * callproc.c (init_callproc):
2648 * charset.c (init_charset):
2649 * fileio.c (check_existing, check_executable, check_writable)
2651 * lread.c (openp, load_path_check):
2652 * process.c (allocate_pty):
2654 Use effective UID when checking permissions, not real UID.
2655 * callproc.c (init_callproc):
2656 * charset.c (init_charset):
2657 * lread.c (load_path_check, init_lread):
2658 Test whether directories are accessible, not merely whether they exist.
2659 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2660 * fileio.c (check_existing, check_executable, check_writable)
2662 Use symbolic names instead of integers for the flags, as they're
2664 (check_writable): New arg AMODE. All uses changed.
2665 Set errno on failure.
2666 (Ffile_readable_p): Use faccessat, not stat + open + close.
2667 (Ffile_writable_p): No need to call check_existing + check_writable.
2668 Just call check_writable and then look at errno. This saves a syscall.
2669 dir should never be nil; replace an unnecessary runtime check
2670 with an eassert. When checking the parent directory of a nonexistent
2671 file, check that the directory is searchable as well as writable, as
2672 we can't create files in unsearchable directories.
2673 (file_directory_p): New function, which uses 'stat' on most platforms
2674 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2675 (Ffile_directory_p, Fset_file_times): Use it.
2676 (file_accessible_directory_p): New function, which uses a single
2677 syscall for efficiency.
2678 (Ffile_accessible_directory_p): Use it.
2679 * xrdb.c (file_p): Use file_directory_p.
2680 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2681 * lread.c (openp): When opening a file, use fstat rather than
2682 stat, as that avoids a permissions race. When not opening a file,
2683 use file_directory_p rather than stat.
2684 (dir_warning): First arg is now a usage string, not a format.
2685 Use errno. All uses changed.
2686 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2687 that merely introduced a race.
2688 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2689 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2690 and similarly for the other O_* flags.
2691 * w32.c (sys_faccessat): Rename from sys_access and switch to
2692 faccessat's API. All uses changed.
2693 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2694 (magic_db): Rename from magic_file_p.
2695 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2696 char *, so that we don't have to test for file existence
2697 separately from opening the file for reading. This removes a race
2698 fixes a permission-checking problem, and simplifies the code.
2700 (file_p): Remove; no longer needed.
2702 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2704 Omit glyphs initialization at startup.
2705 * dispnew.c (glyphs_initialized_initially_p): Remove.
2706 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2707 (Fredraw_frame): Move actual code from here...
2708 (redraw_frame): ...to here. Add eassert. Adjust comment.
2709 (Fredraw_display): Use redraw_frame.
2710 * xdisp.c (clear_garbaged_frames): Likewise.
2712 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2714 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2715 passed to pint2str and pint2hrstr to be at most the size of the
2716 frame's decode_mode_spec_buffer. This avoids crashes with very
2717 large values of FIELD_WIDTH argument to decode_mode_spec.
2720 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2722 Fix a race with verify-visited-file-modtime (Bug#12863).
2723 Since at least 1991 Emacs has ignored an mtime difference of no
2724 more than one second, but my guess is that this was to work around
2725 file system bugs that were fixed long ago. Since the race is
2726 causing problems now, let's remove that code.
2727 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2728 whose time stamp is off by no more than a second. Insist that the
2729 file time stamps match exactly.
2731 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2733 * frame.h (struct frame): Convert external_tool_bar member to
2734 1-bit unsigned bitfield.
2735 * termhooks.h (struct terminal): Remove mouse_moved member since
2736 all users are long dead. Adjust comment on mouse_position_hook.
2738 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2740 Simplify by using FOR_EACH_FRAME here and there.
2741 * frame.c (next_frame, prev_frame, other_visible_frames)
2742 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2743 * w32term.c (x_window_to_scroll_bar): Likewise.
2744 * window.c (window_list): Likewise.
2745 * xdisp.c (x_consider_frame_title): Likewise.
2746 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2747 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2748 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2749 * xmenu.c (menubar_id_to_frame): Likewise.
2750 * xselect.c (frame_for_x_selection): Likewise.
2751 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2752 (x_window_to_menu_bar): Likewise.
2753 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2755 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2757 * data.c (Qdefalias_fset_function): Now static.
2759 Another tweak to vectorlike_header change.
2760 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2761 Remove, and replace all uses with ...
2762 (next_in_free_list, set_next_in_free_list):
2763 New functions, which respect C's aliasing rules better.
2765 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2767 * window.c (list4i): Rename from 'quad'. All uses changed.
2768 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2770 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2772 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2773 warning about mixing declarations and code in ISO C90.
2775 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2777 * window.c (Fsplit_window_internal): Set combination limit of
2778 new parent window to t iff Vwindow_combination_limit is t;
2779 fixing a regression introduced with the change from 2012-09-22.
2780 (Fset_window_combination_limit): Fix doc-string.
2782 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2784 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2785 amount when the scroll margins are too large. When scrolling
2786 backwards in the buffer, give up if cannot reach point or the
2787 scroll margin within a reasonable number of screen lines.
2788 Fixes point position in window under scroll-up/down-aggressively when
2789 point is positioned many lines beyond the window top/bottom.
2792 * ralloc.c (relinquish): If real_morecore fails to return memory
2793 to the system, don't crash; instead, leave the last heap
2794 unchanged and return. (Bug#12774)
2796 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2798 * lisp.h (AUTOLOADP): New macro.
2799 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2800 * data.c (Ffset): Remove special ad-advice-info handling.
2801 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2803 (Finteractive_form): Simplify.
2804 (Fquo): Don't insist on having at least 2 arguments.
2805 (Qdefalias_fset_function): New var.

2824 Tweak last vectorlike_header change.
2825 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2826 vectorlike object on the free list. This is introduced to avoid
2827 some (but not all) pointer casting and aliasing problems, see
2828 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2829 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2833 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2835 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2861 special hash function containing a comparison that always yields 1.
2863 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2865 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2866 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2867 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2870 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2872 * image.c (xpm_make_color_table_h): Fix compiler error because
2873 make_hash_table changed.
2875 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2877 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2879 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2881 Use ad-hoc comparison function for the profiler's hash-tables.
2882 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2883 (make_log): Use them.
2884 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2885 call Fequal any more.

2894 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2895 (hash_lookup, hash_remove_from_table): Move assertion checking of
2896 hashfn result here. Check hash-equality before calling cmpfn.

2909 value of w32-scroll-lock-modifier is neither nil nor one of the
2910 known key modifiers. (Bug#12806)
2912 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2914 Shrink struct vectorlike_header to the only size field.
2915 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2917 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2918 PVEC_TYPE_MASK to arrange new bitfield in the vector header.

2938 (allocate_vector_from_block): Simplify.
2939 (PSEUDOVECTOR_NBYTES): Replace with...

2942 (allocate_vectorlike): Likewise.
2943 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2944 Add easserts. Adjust XSETPVECTYPESIZE usage.
2945 (allocate_buffer): Use BUFFER_PVEC_INIT.
2946 (live_vector_p): Adjust to match large vector.
2947 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2948 * buffer.h (struct buffer): Add next member.
2949 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2951 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2959 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2961 * keyboard.c (event_to_kboard): Do not dereference
2962 frame_or_window field of SELECTION_REQUEST_EVENT
2963 and SELECTION_CLEAR_EVENT events (Bug#12814).
2964 * xterm.h (struct selection_input_event): Adjust comment.
2966 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2968 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2969 such as Scroll Lock, if the respective keys are treated as
2970 function keys, not as modifiers. This avoids destroying non-ASCII
2971 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2973 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2975 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2977 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2979 Restore some duplicate definitions (Bug#12814).
2980 This undoes part of the 2012-11-03 changes. Some people build
2981 with plain -g rather than with -g3, and they need the duplicate
2982 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2983 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2984 Define as macros, as well as as enums or as constants.
2986 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2988 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2989 to keypad keys (Bug#12816).
2991 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2993 Minor adjustments of recently-changed frame functions.
2994 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2995 known to be a frame (we're in the FRAMEP branch).
2996 * lisp.h (Qframep): Remove decl. frame.h declares this.
2997 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2998 since they're meant for Lisp fixnum values.
3000 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3002 * window.c (Fwindow_combination_limit): Revert to the only
3003 required argument and adjust docstring as suggested in
3004 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3005 by Martin Rudalics <rudalics@gmx.at>.
3007 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3009 Widely used frame validity and checking functions.
3010 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3011 * frame.c (decode_live_frame, decode_any_frame): New functions.
3012 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3013 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3014 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

3021 (frame_buffer_list, frame_buffer_predicate): Remove.
3022 * lisp.h (frame_buffer_predicate): Remove prototype.
3023 * buffer.c (Fother_buffer): Use decode_any_frame.
3024 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3025 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3026 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3027 (Fclose_font, Ffont_info): Use decode_live_frame.
3028 * fontset.c (check_fontset_name): Likewise.
3029 * terminal.c (Fframe_terminal): Likewise.
3030 * w32fns.c (check_x_frame): Likewise.
3031 * window.c (Fminibuffer_window, Fwindow_at)
3032 (Fcurrent_window_configuration): Likewise.
3033 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3034 Likewise. Allow zero number of arguments. Adjust docstring.
3035 * dispnew.c (Fredraw_frame): Likewise.
3036 * xfaces.c (frame_or_selected_frame): Remove.
3037 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3038 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3039 (Fframe_face_alist): Use decode_live_frame.
3040 * xfns.c (check_x_frame): Likewise.
3042 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3044 * window.c (quad): New function.
3045 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3046 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3047 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3048 (Fwindow_line_height): Use it.
3049 (Fwindow_fringes): Use list3.
3050 (Fwindow_scroll_bars): Use list4.
3051 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3052 (Fwindow_combination_limit): Allow zero number of arguments.
3054 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3056 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3058 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3059 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3060 file descriptor 2 for standard error. (Bug#12805)
3062 2012-11-05 Chong Yidong <cyd@gnu.org>
3064 * process.c (wait_reading_process_output): Revert previous change.
3066 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3068 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3069 This removes code that has been obsolete since around 1990.
3070 * callproc.c (Fcall_process):
3072 * process.c (create_process):
3073 * term.c (dissociate_if_controlling_tty):
3074 Assume setsid exists.
3075 * callproc.c (child_setup): Assume setpgid exists and behaves as
3076 per POSIX.1-1988 or later.
3077 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3078 * emacs.c (shut_down_emacs):
3079 * sysdep.c (sys_suspend, init_foreground_group):
3080 Assume getpgrp behaves as per POSIX.1-1998 or later.
3081 * msdos.c (setpgrp): Remove.
3082 (tcgetpgrp, setpgid, setsid): New functions.
3083 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3084 * term.c (no_controlling_tty): Remove; unused.
3085 * w32proc.c (setpgrp): Remove.
3086 (setsid, tcgetpgrp): New functions.
3088 Simplify by assuming __fpending.
3089 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3090 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3091 Do not assume that __fpending's result fits in int.
3093 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3095 Remove EMACS_OUTQSIZE+sleep hack.
3096 * dispnew.c (update_frame_1): Remove hack for terminals slower
3097 than 2400 bps, which throttled Emacs by having it sleep.
3098 This code hasn't worked since at least 2007, when the multi-tty stuff
3099 was added, and anyway those old terminals are long dead.
3100 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3101 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3103 Fix data-loss with --version (Bug#9574).
3104 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3105 as we can't assume that emacs_strerror is initialized, and strerror
3106 is good enough here.
3107 (main): Invoke atexit earlier, to catch earlier instances of
3108 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3110 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3112 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3113 (keyDown): Remap keypad keys to X11 virtual key codes.
3115 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3117 Fix data-loss with --batch (Bug#9574).
3118 * emacs.c: Include <close-stream.h>.
3119 (close_output_streams): New function.
3120 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3121 and handles errors appropriately.
3122 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3125 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3126 The symptom is a diagnostic "GLib-WARNING **: In call to
3127 g_spawn_sync(), exit status of a child process was requested but
3128 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3129 waitpid(), so exit status can't be returned." The diagnostic
3130 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3131 The real bug is a race condition between Emacs and glib: Emacs
3132 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3133 so that glib can't find it. Work around the bug by invoking
3134 waitpid only on subprocesses that Emacs itself creates.
3135 * process.c (create_process, record_child_status_change):
3136 Don't use special value -1 in pid field, as the caller now must
3137 know the pid rather than having the callee infer it.
3138 The inference was sometimes incorrect anyway, due to another race.
3139 (create_process): Set new 'alive' member if child is created.
3140 (process_status_retrieved): New function.
3141 (record_child_status_change): Use it.
3142 Accept negative 1st argument, which means to wait for the
3143 processes that Emacs already knows about. Move special-case code
3144 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3145 processes that have already been waited for, by testing and
3146 clearing new 'alive' member.
3147 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3148 now does this internally.
3149 (handle_child_signal): Let record_child_status_change do all
3150 the work, since we do not want to reap all exited child processes,
3151 only the child processes that Emacs itself created.
3152 * process.h (Lisp_Process): New boolean member 'alive'.
3154 Omit duplicate definitions no longer needed with gcc -g3.
3155 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3156 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3157 Define only as macros. There's no longer any need to also define
3158 these symbols as enums or as constants, since we now assume
3159 gcc -g3 when debugging.
3161 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3163 * lisp.mk: Adjust comments to the fact that term/internal is now
3164 loaded from loadup.el.
3166 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3167 (msdos_fatal_signal): New function.
3168 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3171 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3172 for GCC versions before 4.
3173 (emacs_raise): Define to call msdos_fatal_signal.
3175 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3176 iterator when starting in the middle of a display or overlay
3179 2012-11-03 Chong Yidong <cyd@gnu.org>
3181 * process.c (wait_reading_process_output): Clean up the last
3184 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3186 * process.c (wait_reading_process_output): Avoid a race condition
3187 with SIGIO delivery (Bug#11536).
3189 2012-11-03 Chong Yidong <cyd@gnu.org>
3191 * buffer.c (cursor_type): Untabify docstring.
3193 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3195 * frame.h (struct frame): Drop can_have_scroll_bars member
3196 which is meaningless for a long time. Adjust comments.
3197 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3198 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3200 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3202 * window.c (decode_next_window_args): Update window arg after
3203 calling decode_live_window and so fix crash reported at
3204 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3205 by Juanma Barranquero <lekktu@gmail.com>.
3206 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3207 * font.c (Ffont_at): Likewise.
3209 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3211 * widget.c (resize_cb): New function.
3212 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3213 (EmacsFrameResize): Check if all is up to date before changing frame
3216 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3218 Implement backtrace output for fatal errors on MS-Windows.
3219 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3220 (BACKTRACE_LIMIT_MAX): New macro.
3221 (w32_backtrace): New function.
3222 (emacs_abort): Use w32_backtrace when the user chooses not to
3223 attach a debugger. Update the text of the abort dialog.
3225 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3227 Window-related stuff cleanup here and there.
3228 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3229 Use decode_any_window.
3230 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3231 * xdisp.c (Fformat_mode_line): Likewise.
3232 * font.c (Ffont_at): Use decode_live_window.

3237 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3238 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3241 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3243 Remove pad from struct input_event.
3244 * termhooks.h (struct input_event): Remove padding field.
3246 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3247 member is never cons for a long time. Adjust comment.
3248 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3249 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3250 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3251 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3253 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3255 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3257 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3259 Fix crash when using Emacs as commit editor for git (Bug#12697).
3260 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3261 and it is configured in conf_post.h.
3262 (Fcall_process): Don't invoke both setsid and setpgid; the former
3263 is enough, if it exists.
3264 * callproc.c (Fcall_process, child_setup):
3265 * process.c (create_process): Use setpgid.
3266 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3268 * dispnew.c (init_display): Initialize the foreground group
3269 if we are running a tty display.
3270 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3271 * lisp.h (init_foreground_group): New decl.
3272 * sysdep.c (inherited_pgroup): New static var.
3273 (init_foreground_group, tcsetpgrp_without_stopping)
3274 (narrow_foreground_group, widen_foreground_group): New functions.
3275 (init_sys_modes): Narrow foreground group.
3276 (reset_sys_modes): Widen foreground group.
3278 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3280 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3282 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3284 * minibuf.c (read_minibuf): Restore current buffer since
3285 choose_minibuf_frame calling Fset_frame_selected_window may
3286 change it (Bug#12766).
3288 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3290 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3292 2012-10-30 Kenichi Handa <handa@gnu.org>
3294 * font.c (Ffont_at): If WINDOW is specified and it is not
3295 displaying the current buffer, signal an error.
3297 2012-10-29 Daniel Colascione <dancol@dancol.org>
3299 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3300 In preparation for fixing bug#12739, move these functions from
3303 * coding.h, coding.c: ... to here, and compile them only when
3304 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3305 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3307 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3309 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3310 (timer_loop, getitimer, setitimer): Use it instead of
3311 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3313 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3316 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3318 * nsterm.m (NO_APPDEFINED_DATA): New define.
3319 (last_appdefined_event_data): New variable
3320 (last_appdefined_event): Remove.
3321 (ns_select): Initialize t from last_appdefined_event_data instead
3322 of [last_appdefined_event data1].
3323 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3324 remove last_appdefined_event (Bug#12698).
3326 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3328 * frame.c (x_set_font): Catch internal error.
3330 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3332 Avoid overflow in w32 implementation of interval timers.
3333 When possible, for ITIMER_PROF count only times the main thread
3335 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3336 'volatile ULONGLONG' types. All the other data which was
3337 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3338 (GetThreadTimes_Proc): New typedef.
3339 (w32_get_timer_time): New function, returns a suitable time value
3341 (timer_loop): Enter critical section when accessing ULONGLONG
3342 values of the itimer_data struct, as these accesses are no longer
3343 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3344 Remove unused variable.
3345 (init_timers): Initialize s_pfn_Get_Thread_Times.
3346 (start_timer_thread): Don't assign itimer->caller_thread here.
3347 (getitimer): Assign itimer->caller_thread here.
3348 (setitimer): Always call getitimer to get the value of ticks_now.
3349 (sys_spawnve): Avoid compiler warning about format mismatch.
3351 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3353 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3354 mouse movement events if the menu bar is active. This avoids
3355 producing a busy "hour-glass" cursor by Windows if the mouse
3356 pointer is positioned over a tooltip shown for some menu item.
3358 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3360 Don't assume process IDs fit in int.
3361 * emacs.c (shut_down_emacs) [!DOS_NT]:
3362 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3363 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3364 Use pid_t, not int, to store process IDs, as 'int'
3365 is not wide enough on a few platforms (e.g., AIX and IRIX).
3367 2012-10-23 Kenichi Handa <handa@gnu.org>
3369 The following change is to make face-font-rescale-alist work
3370 correctly for non-ASCII fonts.
3372 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3373 (font_open_for_lface): Handle Vface_font_rescale_alist.
3375 2012-10-23 Chong Yidong <cyd@gnu.org>
3377 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3379 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

3385 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3388 2012-10-21 Glenn Morris <rgm@gnu.org>
3390 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3392 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3394 Port to OpenBSD 5.1.
3395 * frame.c (Fmouse_position, Fmouse_pixel_position):
3396 * xdisp.c (produce_stretch_glyph):
3397 Declare local vars only when they're needed.
3398 This is clearer and avoids a warning on OpenBSD about unused vars.
3399 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3400 This is safer, and avoids OpenBSD warnings about unused vars.
3401 * keyboard.c (record_menu_key): Remove unnecessary decl.
3402 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3403 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3404 as our definition clashes with OpenBSD's.
3405 * xfaces.c (load_face_colors, check_lface_attrs)
3406 (get_lface_attributes_no_remap, get_lface_attributes)
3407 (lface_fully_specified_p, x_supports_face_attributes_p)
3408 (tty_supports_face_attributes_p, face_fontset, realize_face)
3409 (realize_x_face, realize_tty_face):
3410 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3411 merely Lisp_Object *. This is more informative and avoids
3412 a warning on OpenBSD about accessing beyond an object's size.
3414 2012-10-20 Chong Yidong <cyd@gnu.org>
3416 * lread.c (Fload): Doc fix (Bug#12592).
3418 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3420 * font.c (Ffont_at): Fix previous change.
3422 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3424 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3425 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

3442 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3443 (staticpro): If we run out of staticpro slots, die with an
3444 informative error instead of just calling emacs_abort.
3446 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3448 Fix two flaws reported by Dmitry Antipov.

3667 keyboard.c, keymap.c: Use bool for booleans.

3703 since unsigned is guaranteed to have that behavior and signed is not.

3705 (get_input_pending): Remove first argument, since it was always
3706 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3707 and behave as if it had that value. Return new value of
3708 input_pending. All callers changed.
3709 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3710 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3737 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3739 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3741 * commands.h (immediate_quit): Remove duplicate decl.
3743 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3745 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3748 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3750 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3752 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3753 match what GetLastError returns. Explain why the function is
3756 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3757 'is_tooltip_frame', to avoid confusion with its global namesake.
3759 2012-10-08 Daniel Colascione <dancol@dancol.org>
3761 * xdisp.c (start_hourglass): Call w32_note_current_window when
3762 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3763 build that caused Emacs to display the hourglass cursor forever.
3765 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3766 which is broken under remote desktop, calculate the number of
3767 colors available for a display based on the display's number of
3768 planes and number of bits per pixel per plane. (bug#10397).
3770 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3772 * nsfont.m (Vfonts_in_cache): New variable.
3773 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3774 are used. Add cached fonts to Vfonts_in_cache.
3775 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3777 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3779 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3781 (FONT_H): Define after FRAME_H.
3782 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3783 Update dependencies.
3785 * w32term.c: Remove leftover declaration of keyboard_codepage.
3787 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3789 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3790 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3791 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3792 (GLOBAL_SOURCES): Add cygw32.c.
3793 ($(BLD)/unexw32.$(O)):
3795 ($(BLD)/w32console.$(O)):
3796 ($(BLD)/w32fns.$(O)):
3797 ($(BLD)/w32heap.$(O)):
3798 ($(BLD)/w32menu.$(O)):
3799 ($(BLD)/w32proc.$(O)): Add w32common.h.
3801 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3803 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3805 2012-10-08 Daniel Colascione <dancol@dancol.org>
3807 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3808 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3809 accidental message numbering hole. Change other messages to
3812 * w32select.h (HAVE_W32SELECT): Remove.
3814 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3815 w32common.h instead of w32heap.h.
3817 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3818 (get_allocation_unit, get_processor_type, get_w32_major_version)
3819 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3820 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3821 (OS_NT, os_subtype, cache_system_info): Move declarations to
3824 * w32heap.c: Include w32common.h.
3825 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3826 (w32_minor_version, w32_build_number, w32_subtype):
3827 Remove duplicate definitions.
3829 * w32fns.c: Include w32common.h; include w32heap.h only in
3832 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3833 Use `report_file_error' instead of `error' in order to better
3834 inform users of what went wrong. Increase NTGUI_UNICODE file
3835 dialog box file name length to 32k, the maximum allowed by the NT
3838 * w32common.h: New file.
3839 (ROUND_UP, ROUND_DOWN, get_page_size)
3840 (get_allocation_unit, get_processor_type, get_w32_major_version)
3841 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3842 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3843 (OS_NT, os_subtype, cache_system_info): Move here.
3845 * unexw32.c, unexcw.c: Include w32common.h.
3847 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3848 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3849 to call syms_of_w32select.
3851 * cygw32.h: Remove obsolete EXFUN declarations.
3853 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3855 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3856 of w32inevt.o from SOME_MACHINE_OBJECTS.
3858 2012-10-08 Daniel Colascione <dancol@dancol.org>
3860 * image.c: Permanent fix for JPEG compilation issue --- limit
3861 jpeglib `boolean' redefinition to Cygwin builds.
3863 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3865 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3867 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3870 2012-10-08 Daniel Colascione <dancol@dancol.org>
3872 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3873 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3874 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3875 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3876 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3877 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3878 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3879 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3880 now a supported configuration.
3882 * Makefile.in: consolidate image variables into LIBIMAGE; add
3883 W32_OBJ and W32_LIBS. Compile new files.
3886 (_DebPrint) declare tracing facility for W32 debugging. We need
3887 to unify tracing later.
3889 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3890 unconditional use of W32 Unicode functions. Cygwin runs only on
3891 100% Unicode operating systems.
3893 * cygw32.c: New file. Define Cygwin-specific facilities.
3894 (Fcygwin_convert_path_to_windows)
3895 (Fcygwin_convert_path_from_windows): New user functions for
3896 accessing Cygwin path-munging routines.
3898 * cygw32.h: New file.
3899 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3900 UTF-16LE strings temporarily inside non-Lisp-visible string
3903 (w32_strerror): Just what it says on the tin.
3905 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3906 also run for Cygwin; both systems have the same problem with using
3907 GUI facilities in a forked child. Also call syms_of_cygw32,
3908 syms_of_w32select in correct places.
3910 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3911 needs fork-then-exec for daemon launching.
3913 * font.h: Include frame.h.
3915 * image.c: Use the image library cache machinery only when we're
3916 compiling for native WINDOWSNT; Cygwin can use shared libraries
3917 like any other Unixlike system.
3919 * keyboard.c: Clarify a comment regarding the input loop.
3921 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3922 functions directly instead of trying to detect at runtime that our
3923 host operating system supports them. We make this change for two
3924 reasons: Cygwin lacks support for the multibyte character
3925 conversion functions used by the legacy menu code, and Cygwin
3926 never needs to rely on non-Unicode APIs.
3928 * unexw32.c (hinst): Declare extern.
3930 * w32.c: Change header order;
3931 (w32_strerror): Move to w32fns.c because we need it for
3932 non-WINDOWSNT builds.
3934 * w32.h: Add #error macro to make sure we don't include w32.h for
3935 Cygwin builds. Remove w32select declarations.
3937 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3938 w32fns.c. w32console.c is WINDOWSNT-only.
3940 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3941 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3943 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3944 (w32_major_version, w32_minor_version, w32_build_number)
3945 (os_subtype, sound_type): Define here
3946 (w32_defined_color): Make color parameter const for consistency
3947 with other _defined_color functions.
3948 (w32_createwindow): Unconditionally call w32_init_class instead of
3949 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3950 through the code is complex and unnecessary because class
3951 registration is practically free.
3952 (w32_name_of_message): New EMACSDEBUG-only function.
3953 (Fset_message_beep): Move here
3954 (Fx_open_connection): Require that the display name for Windows be
3955 "w32" for consistency, emacsclient disambiguation, and maybe, one
3956 day, multi-window-system support.
3957 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3958 Cygwin files for W32 GUI facilities, since these clearly don't
3959 expect Cygwin names.
3960 (_DebPrint): Define.
3961 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3962 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3963 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3964 (w32_last_error): Remove.
3966 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3968 * w32heap.c (syspage_mask): Declare here.
3969 (cache_system_info): Remove.
3971 * w32inevt.c (faked_key): Define globally, not statically.
3972 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3973 (w32_console_toggle_lock_key): Move to w32fns.c.
3975 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3977 * w32proc.c (_DebPrint): Move to w32fns.c.
3978 * w32select.c: Include string.h, stdio.h for Cygwin.
3979 * w32select.h: New File.
3981 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3983 (w32_message_fd): New variable. Under Cygwin, holds the file
3984 descriptor the system used to tell us about pending thread
3987 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3988 that prevented compilation under non-WINDOWSNT systems.
3990 (w32_initialize): Open /dev/windows and assign it to
3991 w32_message_fd. Provide w32 feature.
3993 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3994 (WM_EMACS_INPUT_READY): add.
3995 (prepend_msg, w32_message_fd): Declare globally.
3998 (keyboard_handle): Use only when WINDOWSNT.
3999 (notify_msg_ready): New function. Posts a message to the main
4000 thread's message queue under CYGWIN, which wakes up the main
4001 thread from select(2) by making the /dev/windows file descriptor
4002 ready. Under WINDOWSNT, it sets an event the same way the old
4005 (post, prepend_msg): Actually call notify_msg_ready instead of
4006 setting the input event directly.
4008 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4010 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4011 but it still has blocs in it, don't return it to the system,
4012 instead of aborting. (Bug#12402)
4014 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4016 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4018 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4019 MAC_OS_X_VERSION_10_6.
4020 (syms_of_nsterm): Remove comment about Panther and above for
4022 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4023 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4024 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4026 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4027 MAC_OS_X_VERSION_10_4.
4029 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4030 MAC_OS_X_VERSION_10_2.
4032 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4034 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4035 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4037 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4038 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4039 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4040 Remove ns_in_resize check.
4041 (ns_clear_frame_area): Remove resize handle code.
4043 * nsfns.m (ns_in_resize): Remove.
4044 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4045 Remove ns_in_resize check.
4047 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4049 Improve sys_siglist detection.
4050 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4051 defined as a macro, as is done in Solaris.
4052 (sys_siglist_entries): New macro.
4053 (save_strsignal): Use it.
4054 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4055 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4057 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4059 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4060 fullscreen/Fullscreen.
4062 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4063 tobar_height is new.
4065 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4066 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4067 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4068 (windowDidResize:): Check for correct window if old style fullscreen.
4069 Capitalize word in comment. Remove incorrect comment.
4070 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4071 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4072 error in drawing background.
4073 (toggleFullScreen:): Remove comment. Rearrange calls.
4074 Set toolbar values to zero, save old height in tobar_height.
4075 Restore tool bar height when leaving fullscreen.
4076 (canBecomeMainWindow): New function.
4078 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4080 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4082 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4084 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4086 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4087 that time stamps of directories could also be changed.
4088 Don't request the too broad GENERIC_WRITE, only the more restrictive
4089 FILE_WRITE_ATTRIBUTES access rights.
4091 * fileio.c (Fset_file_times): Special-case ignoring errors for
4092 directories only on MSDOS, not on MS-Windows.
4094 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4096 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4098 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4100 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4101 see whether CreateFile failed.
4103 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4105 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4106 to avoid similar races.
4107 * keyboard.c (pending_signals): Now bool, not int.
4109 Port timers to OpenBSD, plus check for timer failures.
4110 OpenBSD problem reported by Han Boetes.
4111 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4113 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4114 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4115 like OpenBSD, which has timer_settime but does not declare it.
4116 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4117 whether to use itimerspec-related primitives. All uses of
4118 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4120 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4122 * profiler.c (handle_profiler_signal): Fix a malloc race
4123 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4125 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4127 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4129 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4131 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4132 consistent with the change in return value of 'safe_strsignal'.
4134 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4136 Prefer plain 'static' to 'static inline' (Bug#12541).
4137 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4138 (bidi_set_sor_type, bidi_push_embedding_level)
4139 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4140 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4141 (bidi_cache_search, bidi_cache_ensure_space)
4142 (bidi_cache_iterator_state, bidi_cache_find)
4143 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4144 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4145 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4146 Now 'static', not 'static inline'.
4148 Count overruns when profiling; change units to ns.
4149 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4150 Give extra weight to samples after overruns, to attempt to count
4151 the time more accurately.
4152 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4153 the underlying primitives nominally do ns.
4154 (Fprofiler_cpu_start): Document the change. Mention that
4155 the sampling intervals are only approximate.
4157 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4159 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4161 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4162 case for the special 0 coding-system.
4164 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4165 (Fmake_overlay): Remove redundant tests.
4166 (fix_start_end_in_overlays): Remove redundant recentering.
4168 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4170 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4171 Update dependencies.
4173 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4175 Fix a malloc race condition involving strsignal.
4176 A signal can arrive in the middle of a malloc, and Emacs's signal
4177 handler can invoke strsignal, which can invoke malloc, which is
4178 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4179 Fix it by altering the signal handler so that it does not invoke
4181 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4182 * process.c (status_message): Use const pointer, in case strsignal
4183 is #defined to safe_strsignal.
4184 * sysdep.c (sys_siglist, init_signals): Always define and
4185 initialize a substitute sys_siglist if the system does not define
4186 one, even if HAVE_STRSIGNAL.
4187 (safe_strsignal): Rename from strsignal. Always define,
4188 using sys_siglist. Return a const pointer.
4189 * syssignal.h (safe_strsignal): New decl.
4190 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4192 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4194 * w32proc.c (timer_loop): Fix code that waits for timer
4195 expiration, to avoid high CPU usage.
4197 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4199 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4200 (sweep_weak_table): Remove redundant prototypes.
4202 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4204 * emacs.c: Move the inclusion of TERM_HEADER after including
4205 windows.h on WINDOWSNT. This avoids compilation problems with
4208 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4210 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4211 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4212 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4213 as the previous version used 'void *'.
4215 * ralloc.c (ROUNDUP): Fix last change.
4216 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4219 * w32proc.c <disable_itimers>: New static flag.
4220 (init_timers): Initialize it to zero, after creating the critical
4221 sections used by the timer threads.
4222 (term_timers): Set to 1 before deleting the critical sections.
4223 (getitimer, setitimer): If disable_itimers is non-zero, return an
4224 error indication without doing anything. Reported by Fabrice
4225 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4226 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4228 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4231 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4232 term_ntproc after all the other bookkeeping, to get timers working
4233 as long as possible.
4235 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4237 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4238 Suggested by Juri Linkov in
4239 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4241 Prefer plain 'static' to 'static inline' (Bug#12541).
4242 With static functions, modern compilers inline pretty well by
4243 themselves; advice from programmers often hurts as much as it helps.
4244 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4245 this change shrinks the text size of the Emacs executable by 1.1%
4246 without affecting CPU significantly in my benchmark.
4247 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4326 (bidi_copy_it): Do the whole copy with a single memcpy.
4327 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4329 Revert the FOLLOW-SYMLINKS change for file-attributes.
4330 Doing it right would require several changes to Tramp, and there's
4331 not enough time to get that tested before the freeze today.
4332 * dired.c (directory_files_internal, Ffile_attributes):
4335 * frame.c (x_report_frame_params): Port better to wider ints.
4336 Do not assume that EMACS_UINT is the same width as uprintmax_t,

4372 compatibility with x64.
4374 * vm-limit.c (lim_data): Now size_t.
4375 (check_memory_limits): Adjust prototypes of real_morecore and
4376 __morecore to receive argument of type ptrdiff_t. Use size_t for

4529 Profiler improvements: more-accurate timers, overflow checks.
4530 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4531 signal.h, setjmp.h. Include systime.h instead.
4532 (saturated_add): New function.

4539 All uses changed to store the new value.
4540 (handle_profiler_signal): Rename from sigprof_handler_1,
4541 for consistency with other handlers. Do not check whether
4542 cpu_log is a hash-table if garbage collecting, since it
4543 doesn't matter in that case.

4545 for consistency with other handlers.
4546 (setup_cpu_timer): New function, with much of what used to be in
4547 Fprofiler_cpu_start. Check for out-of-range argument.
4548 Prefer timer_settime if available, and prefer
4549 thread cputime clocks, then process cputime clocks, then
4550 monotonic clocks, to the old realtime clock. Use make_timeval
4551 to round more-correctly when falling back to setitimer.
4552 (Fprofiler_cpu_start): Use it.
4553 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4554 Don't assume that passing NULL as the 2nd argument of setitimer
4555 is the same as passing a pointer to all-zero storage.
4556 Ignore SIGPROF afterwards.
4557 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4558 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4559 non-fatal signal handlers. Ignore SIGPROF on startup.
4560 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4561 in profiler.c, since sysdep.c now uses it.
4563 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4619 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4620 Since this stuff is now private to charset.c, there's no need for
4621 a public macro and no need to inline by hand.

4652 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4654 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4656 Prefer POSIX timers if available.
4657 They avoid a race if the timer is too close to the current time.
4658 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4659 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4660 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4662 2012-09-25 Eli Zaretskii <eliz@gnu.org>

4667 STRING_CHAR_ADVANCE.
4669 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4671 Move Vlibrary_cache to emacs.c and reset before dumping.
4673 * lisp.h (reset_image_types): Declare.
4674 [WINDOWSNT] (Vlibrary_cache): Declare.
4676 * image.c (reset_image_types): New function.
4678 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

4685 * w32.h (Vlibrary_cache): Do not declare.
4687 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4689 * w32proc.c (sys_signal): Handle all signals defined by the
4690 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4691 handlers for signals supported by Windows. Don't override
4692 term_ntproc as the handler for SIGABRT.
4693 (sigaction): Rewrite to call sys_signal instead of duplicating its
4695 (sys_kill): Improve commentary.
4697 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4698 consistency with a signature of a signal handler. All callers
4700 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4701 install term_ntproc as a signal handler for SIGABRT, as that
4702 should be done by the dumped Emacs.
4704 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4706 * w32select.c (term_w32select): Protect against repeated
4707 invocation by setting clipboard_owner to NULL after calling

4711 and term_ntproc to their modified signatures.
4713 * character.c (char_string, string_char): Remove calls to
4714 MAYBE_UNIFY_CHAR. See the discussion starting at
4715 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4718 2012-09-25 Chong Yidong <cyd@gnu.org>

4722 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4724 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4725 when encountering an unknown bytecode.
4727 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4729 image.c, indent.c: Use bool for booleans.
4730 * dispextern.h (struct image_type): Members valid_p, load, init
4731 now return bool, not int. All uses changed.
4732 * image.c: Omit unnecessary static decls.
4733 (x_create_bitmap_mask, x_build_heuristic_mask):
4734 Return void, not int, since callers don't care about the return value.

4763 Use bool for booleans.
4765 2012-09-24 Chong Yidong <cyd@gnu.org>
4767 * chartab.c (Fset_char_table_default): Obsolete function removed.
4769 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4771 Move pid_t related decls out of lisp.h.
4772 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4773 (interruptible_wait_for_termination):
4774 Move these decls from lisp.h to syswait.h, since they use pid_t.
4775 Needed on FreeBSD; see Herbert J. Skuhra in
4776 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4777 * callproc.c: Include syswait.h.

4795 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4796 * xfns.c (Fx_show_tip) [USE_GTK]:
4797 Use bool for boolean.
4798 * gtkutil.c (xg_update_frame_menubar):
4799 * xmenu.c (update_frame_menubar):
4800 Return void, not int, since caller ignores return value.
4801 * gtkutil.c (xg_change_toolbar_position):
4804 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4806 * makefile.w32-in (BLOCKINPUT_H): Remove.

4823 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4825 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4826 fatal_error_backtrace.
4828 * w32proc.c (sys_kill): Undo last change: don't do anything when
4829 invoked to deliver SIGABRT to our own process. This is now
4830 handled by emacs_raise.
4832 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4834 * w32term.c (w32_read_socket): Remove leftover reference to
4835 interrupt_input_pending.
4837 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4839 Do not use SA_NODEFER.
4840 Problem reported by Dani Moncayo in
4841 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4843 * sysdep.c (emacs_abort): Do not reset signal handler.
4844 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4845 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4846 wanted even on POSIXish hosts, and it doesn't work on Windows.
4848 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4850 * xterm.c (x_term_init): Call fixup_locale before and after calling
4851 gtk_init (Bug#12392).
4853 2012-09-23 Chong Yidong <cyd@gnu.org>
4855 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4856 Vdynamic_library_alist.
4858 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4859 (Fgnutls_available_p): Caller changed.
4861 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4862 (Flibxml_parse_xml_region): Likewise.
4864 * dispextern.h (struct image_type): Remove arg from init function.
4866 * image.c (Finit_image_library, lookup_image_type)
4867 (define_image_type): Remove now-unneeded second arg.
4868 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4869 (init_tiff_functions, init_gif_functions, init_svg_functions):
4870 Arglist and w32_delayed_load calling convention changed.
4871 (gs_type): Remove init_gs_functions; there is no such function.
4872 (valid_image_p, make_image): Fix caller to lookup_image_type.
4874 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4876 Simplify and avoid signal-handling races (Bug#12471).
4878 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4879 Avoid recursive loop if there's a fatal error in the function itself.
4880 * atimer.c (pending_atimers):
4881 * blockinput.h: Don't include "atimer.h"; no longer needed.
4882 (interrupt_input_pending): Remove. All uses removed.
4883 pending_signals now counts both atimers and ordinary interrupts.
4884 This is less racy than having three separate pending-signal flags.
4885 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4887 Rename from their upper-case counterparts BLOCK_INPUT,
4888 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4889 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4890 This makes it easier to access volatile variables more accurately.
4891 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4892 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4893 that's more reliable if the code is buggy and sets
4894 interrupt_input_blocked to a negative value. All uses changed.
4895 * atimer.c (deliver_alarm_signal):
4896 Remove. No need to deliver this to the parent; any thread can
4897 handle this signal now. All uses replaced by underlying handler.
4898 * atimer.c (turn_on_atimers):
4899 * dispnew.c (handle_window_change_signal):
4900 * emacs.c (handle_danger_signal):
4901 * keyboard.c (kbd_buffer_get_event):
4902 Don't reestablish signal handler; not needed with sigaction.
4903 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4905 Rework to avoid unnecessary accesses to volatile variables.
4906 (UNBLOCK_INPUT_TO): Now a function.
4907 (totally_unblock_input, unblock_input): New decls.
4908 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4909 (init_data): Remove. Necessary stuff now done in init_signal.
4910 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4911 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4912 (fatal_error_code): Remove; no longer needed.
4913 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4914 it doesn't always backtrace. All uses changed. No need to reset
4915 signal to default, since sigaction and/or die does that for us now.
4916 Use emacs_raise (FOO), not kill (getpid (), FOO).
4917 (main): Check more-accurately whether we're dumping.
4918 Move fatal-error setup to sysdep.c
4919 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4920 * gtkutil.c (xg_get_file_name, xg_get_font):
4921 Remove no-longer-needed signal-mask manipulation.
4922 * keyboard.c, process.c (POLL_FOR_INPUT):
4923 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4924 * keyboard.c (read_avail_input): Remove.
4925 All uses replaced by gobble_input.
4926 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4927 (kbd_buffer_store_event_hold, gobble_input):
4928 (record_asynch_buffer_change) [USABLE_SIGIO]:
4929 (store_user_signal_events):
4930 No need to mess with signal mask.
4931 (gobble_input): If blocking input and there are terminals, simply
4932 set pending_signals to 1 and return. All hooks changed to not
4933 worry about whether input is blocked.
4934 (process_pending_signals): Clear pending_signals before processing
4935 them, in case a signal comes in while we're processing.
4936 By convention callers now test pending_signals before calling us.
4937 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4938 New functions, to support changes to blockinput.h.
4939 (handle_input_available_signal): Now extern.
4940 (reinvoke_input_signal): Remove. All uses replaced by
4942 (quit_count): Now volatile, since a signal handler uses it.
4943 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4944 All callers changed. Block SIGINT only if not already blocked.
4945 Clear sigmask reliably, even if Fsignal returns, which it can.
4946 Omit unnecessary accesses to volatile var.
4947 (quit_throw_to_read_char): No need to restore sigmask.
4948 * keyboard.c (gobble_input, handle_user_signal):
4949 * process.c (wait_reading_process_output):
4950 Call signal-handling code rather than killing ourselves.
4951 * lisp.h: Include <float.h>, for...
4952 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4953 (pending_signals): Now volatile.
4954 (syms_of_data): Now const if IEEE floating point.
4955 (handle_input_available_signal) [USABLE_SIGIO]:
4956 (terminate_due_to_signal, record_child_status_change): New decls.
4957 * process.c (create_process): Avoid disaster if memory is exhausted
4958 while we're processing a vfork, by tightening the critical section
4960 (send_process_frame, process_sent_to, handle_pipe_signal)
4961 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4963 (send_process): No need for setjmp/longjmp any more, since the
4964 SIGPIPE stuff is now gone. Instead, report an error if errno
4966 (record_child_status_change): Now extern. PID and W are now args.
4967 Return void, not bool. All callers changed.
4968 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4969 Remove. All uses removed. This bug should be fixed now in a
4971 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4972 and record the child status change directly. This avoids the
4973 need to futz with the signal mask.
4974 (process_fatal_action): Move here from emacs.c.
4975 (emacs_sigaction_flags): New function, containing
4976 much of what used to be in emacs_sigaction_init.
4977 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4978 caught by emacs, to make races less likely.
4979 (deliver_process_signal): Rename from handle_on_main_thread.
4981 (BACKTRACE_LIMIT_MAX): Now at top level.
4982 (thread_backtrace_buffer, threadback_backtrace_pointers):
4984 (deliver_thread_signal, deliver_fatal_thread_signal):
4985 New functions, for more-accurate delivery of thread-specific signals.
4986 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4987 (deliver_arith_signal): Handle in this thread, not
4988 in the main thread, since it's triggered by this thread.
4989 (maybe_fatal_sig): New function.
4990 (init_signals): New arg DUMPING so that we can be more accurate
4991 about whether we're dumping. Caller changed.
4992 Treat thread-specific signals differently from process-general signals.
4993 Block all signals while handling fatal error; that's safer.
4994 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4996 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4997 Ignore SIGPIPE unless batch.
4998 (emacs_backtrace): Output backtrace for the appropriate thread,
4999 which is not necessarily the main thread.
5000 * syssignal.h: Include <stdbool.h>.
5001 (emacs_raise): New macro.
5002 * xterm.c (x_connection_signal): Remove; no longer needed
5003 now that we use sigaction.
5004 (x_connection_closed): No need to mess with sigmask now.
5005 (x_initialize): No need to reset SIGPIPE handler here, since
5006 init_signals does this for us now.
5008 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5010 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5011 background rect may be larger (Bug#12245).
5013 2012-09-23 Chong Yidong <cyd@gnu.org>
5015 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5017 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5019 * .gdbinit: Just stop at fatal_error_backtrace.
5020 See Stefan Monnier's request in
5021 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5022 Remove no-longer-used query of system type.
5024 2012-09-22 Chong Yidong <cyd@gnu.org>
5026 * search.c (Freplace_match): Doc fix (Bug#12325).
5028 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5030 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5031 (Fline_end_position): Doc fix.
5033 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5035 2012-09-22 Chong Yidong <cyd@gnu.org>
5037 * dispextern.h (struct image_type): Add new slot, storing a type
5038 initialization function.
5040 * image.c (define_image_type): Call the image initializer function
5041 if it is defined. Arguments and return value changed.
5042 (valid_image_p, make_image): Callers changed.
5043 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5044 (gif_type, imagemagick_type, svg_type, gs_type):
5045 Add initialization functions.
5046 (Finit_image_library): Call lookup_image_type.
5047 (CHECK_LIB_AVAILABLE): Macro deleted.
5048 (lookup_image_type): Call define_image_type here, rather than via
5049 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5050 (syms_of_image): Move define_image_type calls for xbm_type and
5051 pbm_type to lookup_image_type.

5055 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5056 'idle_timers' from here ...
5057 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5058 lists, to avoid infloops when the timer does something stupid,
5059 like reinvoke itself with the same or smaller time-out.
5062 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5064 * window.c (Fsplit_window_internal): Handle only Qt value of
5065 Vwindow_combination_limit separately.
5066 (Qtemp_buffer_resize): New symbol.
5067 (Vwindow_combination_limit): New default value.
5070 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5072 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5073 the new overlay string. (Bug#10159)
5075 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5077 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5078 or that fprintf is async-signal-safe. POSIX doesn't require
5081 2012-09-22 Chong Yidong <cyd@gnu.org>
5083 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5086 2012-09-22 Kenichi Handa <handa@gnu.org>
5088 * composite.c (composition_reseat_it): Handle the case that a
5089 grapheme cluster is not covered by a single font (Bug#12352).
5091 2012-09-21 Chong Yidong <cyd@gnu.org>
5093 * image.c (define_image_type): Avoid adding duplicate types to
5094 image_types (Bug#12463). Suggested by Jörg Walter.
5096 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5098 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5099 (print_load_command_name): Add case LC_DATA_IN_CODE.
5100 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5102 2012-09-21 Glenn Morris <rgm@gnu.org>
5104 * eval.c (Frun_hook_with_args_until_success)
5105 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5107 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5109 * fileio.c (Ffile_selinux_context): Only call freecon when
5110 lgetfilecon succeeded.
5111 (Fset_file_selinux_context): Likewise. (Bug#12444)
5113 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5115 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5116 reordering, locate the cursor by calling set_cursor_from_row; if
5117 that fails, clear the desired glyph matrix before returning a
5118 failure indication to the caller. Fixes leaving garbled display
5119 when fast scrolling with a down-key. (Bug#12403)
5120 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5121 scrolling through multibyte text.
5123 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5125 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5126 calling mark_vectorlike since that's the one that marks the window.
5127 (mark_discard_killed_buffers): Mark the final cdr.
5128 * window.h (struct window): Move prev/next_buffers to the
5129 non-standard fields.
5130 * window.c (make_window): Initialize prev/next_buffers manually.
5132 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5134 Omit unused arg EXPECTED from socket hooks.
5135 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5136 * nsterm.m (ns_term_init):
5137 * termhooks.h (struct terminal.read_socket_hook):
5138 * w32inevt.c (w32_console_read_socket):
5139 * w32term.c (w32_read_socket):
5140 * xterm.c (XTread_socket):
5141 Omit unused arg EXPECTED. All callers changed.
5142 (store_user_signal_events): Return void, not int, since callers no
5143 longer care about the return value. All uses changed.
5145 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5147 * w32gui.h (XParseGeometry): Do not declare.
5149 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5151 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5152 Ignore 'expected'. See Eli Zaretskii in
5153 <http://bugs.gnu.org/12471#8> (last line).
5155 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5156 (XParseGeometry): Now static. Substitute extremal values for
5157 values that are out of range.
5159 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5161 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5163 * nsfns.m (XParseGeometry): Remove.
5164 (Fx_create_frame): Call x_set_offset to correctly interpret
5165 top_pos in geometry.
5167 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5168 (Fx_parse_geometry): If there is a space in string, call
5169 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5171 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5173 * search.c (scan_buffer): Use character positions in calls to
5174 region_cache_forward and region_cache_backward, not byte
5175 positions. (Bug#12196)
5177 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5178 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5180 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5181 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5182 emacs_blocked_malloc, now deleted.
5184 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5186 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5187 The workaround was for improving performance on Solaris 2.4, but
5188 is getting in the way now. Emacs will still work if someone is
5189 still running Solaris 2.4 in a museum somewhere; Sun dropped
5190 support for Solaris 2.4 in 2003.
5191 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5192 * process.c (create_process) [HAVE_WORKING_VFORK]:
5193 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5194 since Emacs no longer uses vfork on that platform.
5196 2012-09-17 Glenn Morris <rgm@gnu.org>
5198 * emacs.c: Use COPYRIGHT.
5200 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5202 Remove configure's --without-sync-input option (Bug#12450).
5203 When auditing signal-handling in preparation for cleaning it up,
5204 I found that SYNC_INPUT has race conditions and would be a real
5205 pain to fix. Since it's an undocumented and deprecated
5206 configure-time option, now seems like a good time to remove it.
5207 Also see <http://bugs.gnu.org/11080#16>.
5208 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5209 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5210 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5211 (malloc_hysteresis):
5212 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5213 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5214 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5215 (dont_register_blocks, bytes_used_when_reconsidered)
5216 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5217 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5218 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5219 Remove. All uses removed.
5220 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5221 implementation, one that depends on whether the new macro
5222 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5224 * atimer.c (run_timers, handle_alarm_signal):
5225 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5226 (handle_async_input, process_pending_signals)
5227 (handle_input_available_signal, init_keyboard):
5228 * nsterm.m (ns_read_socket):
5229 * process.c (wait_reading_process_output):
5230 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5231 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5233 * xterm.c (XTread_socket):
5235 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5236 * eval.c (handling_signal): Remove. All uses removed.
5237 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5238 All uses replaced with the SYNC_INPUT version.
5239 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5241 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5244 * font.c (Ffont_shape_gstring): Remove unused local.
5246 2012-09-16 Glenn Morris <rgm@gnu.org>
5248 * Makefile.in (clean): No longer run nextstep's clean.
5250 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5252 (ns-app): Move here from ns.mk, and simplify.
5253 (clean): Simplify nextstep entry.
5254 * ns.mk: Remove file.
5256 2012-09-17 Kenichi Handa <handa@gnu.org>
5258 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5259 not covert the last few charactes.
5261 2012-09-16 Kenichi Handa <handa@gnu.org>
5263 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5264 here, but just check the validity of glyphs in the glyph-string.
5266 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5268 * window.c (Fwindow_parameter, Fset_window_parameter):
5269 Accept any window as argument (Bug#12452).
5271 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5273 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5274 to ns_term_init to avoid memory leak.
5276 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5277 explicit retain/release.
5278 (ns_term_init): Only allow one display. Initialize outerpool and
5281 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5283 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5284 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5285 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5286 the Microsoft problem in a different way, by altering ../nt/config.nt.
5288 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5303 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5304 by lisp.h. This completes removal of setjmp.h inclusion
5305 erroneously announced in the previous commit. (Bug#12446)
5307 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5310 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5311 not defined as a macro. The latter happens on MS-Windows.
5314 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5316 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5317 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5318 Some instances of '#include <setjmp.h>' removed, if the
5319 only reason for the instance was because "lisp.h" was included.
5320 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5321 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5322 and _longjmp with the new symbols. Emacs already uses _setjmp if
5323 available, so this change affects only POSIXish hosts that have
5324 sigsetjmp but not _setjmp, such as some versions of Solaris and
5325 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5326 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5327 (png_load_body) [HAVE_PNG]:
5328 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5329 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5330 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5331 since PNG requires jmp_buf. This is the only exception to the
5332 general rule that we now use sys_setjmp and sys_longjmp.
5333 This exception is OK since this code does not change the signal
5334 mask or longjmp out of a signal handler.
5336 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5338 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5339 Include "syssignal.h", for 'main_thread'.
5341 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5343 Avoid out-of-range marker position (Bug#12426).
5344 * insdel.c (replace_range, replace_range_2):
5345 Adjust markers before overlays, as suggested by comments.
5346 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5347 Remove redundant check before calling offset_intervals.
5349 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5351 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5352 current buffer (Bug#12387).
5354 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5356 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5358 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5360 Use a more backwards-compatible timer format (Bug#12430).
5361 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5362 vector element, not from the 4th, since PSECS is now at the end.
5363 (Fcurrent_idle_time): Doc fix.
5365 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5367 Function to mark objects and remove killed buffers at once.
5368 * alloc.c (discard_killed_buffers): Rename to ...
5369 (mark_discard_killed buffers) ... new name. Add marking
5370 of remaining objects. Fix comment. Adjust users.
5371 (mark_object): Do not touch frame buffer lists here.
5372 * frame.c (delete_frame): Reset frame buffer lists here.
5374 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5376 Better workaround for GNOME bug when --enable-gcc-warnings.
5377 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5378 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5379 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5381 Simplify SIGIO usage (Bug#12408).
5382 The code that dealt with SIGIO was crufty and confusing, e.g., it
5383 played tricks like "#undef SIGIO" but these tricks were not used
5384 consistently. Simplify mostly by not #undeffing standard symbols,
5385 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5386 or not as we please) rather than "defined SIGIO" (standard symbol
5387 that we probably shouldn't #undef).
5388 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5389 Modules that need it can include it.
5390 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5391 * dispextern.h (ignore_sigio): New decl.
5392 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5393 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5394 * emacs.c (shut_down_emacs):
5395 * keyboard.c (kbd_buffer_store_event_hold):
5396 Use ignore_sigio rather than invoking 'signal' directly.
5397 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5399 (FIONREAD, SIGIO): Do not #undef.
5400 (tty_read_avail_input): Use #error rather than a syntax error.
5401 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5402 for I_PIPE, used by SETUP_SLAVE_PTY.
5403 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5404 * sysdep.c (croak): Remove; no longer needed. This bit of
5405 temporary code, with Fred N. Fish's comment that it's temporary,
5406 has been in Emacs since at least 1992!
5407 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5408 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5409 * syssignal.h (croak): Remove decl.
5410 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5411 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5412 now that we're termios-only.
5413 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5414 * term.c (dissociate_if_controlling_tty): Use #error rather than
5417 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5418 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5419 to work around GNOME bug 683906.
5420 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5421 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5422 This works around GCC bug 54561.
5424 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5426 More fixes for 'volatile' and setjmp/longjmp.
5427 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5428 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5429 (png_load_body) [HAVE_PNG]:
5430 (jpeg_load_body) [HAVE_JPEG]:
5431 New function, with most of the old parent function's body.
5432 (png_load) [HAVE_PNG]:
5433 (jpeg_load) [HAVE_JPEG]:
5434 Invoke the new function, to avoid longjmp munging our locals.
5435 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5436 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5437 longjmp is passed 2, as the C standard doesn't guarantee this.
5438 Instead, store the failure code into mgr->failure_code.
5440 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5442 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5443 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5444 (syms_of_keyboard): Remove support for unread-command-char.
5446 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5448 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5449 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5450 violation. (Bug#12426)
5452 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5454 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5456 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5458 * eval.c: Add `inhibit-debugger'.
5459 (Qinhibit_debugger): New symbol.
5460 (call_debugger): Bind it instead of Qdebug_on_error.
5461 (maybe_call_debugger): Test Vinhibit_debugger.
5462 (syms_of_eval): Define inhibit-debugger.
5463 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5464 (syms_of_xdisp): Remove inhibit-debug-on-message.
5466 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5468 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5469 If a nonvolatile local variable is written before a _longjmp to
5470 the frame containing the variable, and is read after the _longjmp,
5471 the value read is indeterminate. Some local variables of type
5472 'struct handler' and 'struct catchtag' are used in this way, so
5473 mark each of their slots as volatile if the slot can be set before
5474 _longjmp and read afterwards.
5475 * lisp.h (struct handler): var and chosen_clause are now volatile.
5476 (struct catchtag): val, next, and pdlcount are now volatile.
5478 * bidi.c (bidi_push_it, bidi_pop_it):
5479 * fns.c (copy_hash_table):
5480 * image.c (define_image_type):
5481 * keyboard.c (kbd_buffer_store_event_hold):
5482 * process.c (Fprocess_send_eof):
5483 * xfaces.c (x_create_gc) [HAVE_NS]:
5484 * xgselect.c (xg_select):
5485 Prefer assignment to memcpy when either will do.
5487 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5488 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5489 time an item is removed. No need to mark this function 'inline';
5490 the compiler knows better than we do.
5492 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5494 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5495 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5496 to change_frame_size (Bug#12388).
5497 (windowDidResize:): Pass YES to updateFrameSize.
5499 * nsterm.h: Add delay parameter to updateFrameSize.
5501 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5503 Discard killed buffers from deleted window and frame objects.
5504 This reduces an amount of references to killed buffers and
5505 helps GC to reclaim them faster.
5506 * alloc.c (discard_killed_buffers): New function.
5507 (mark_object): Use it for deleted windows and frames.
5508 (mark_object): If symbol's value is set up for a killed buffer
5509 or deleted frame, restore its global binding.
5510 * data.c (swap_in_global_binding): Add GC notice.
5511 (swap_in_symval_forwarding): Use convenient set_blv_where.
5512 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5513 * window.h: ... to here.
5515 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5517 Convenient macro to check whether the buffer is live.
5518 * buffer.h (BUFFER_LIVE_P): New macro.
5519 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5520 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5522 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5524 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5525 composition cases (Bug#12364).
5527 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5528 overhang of succeeding glyphs overlapping box cursor.
5530 * w32term.c (x_draw_glyph_string): Likewise.
5532 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5534 Simplify, document, and port floating-point (Bug#12381).
5535 The porting part of this patch fixes bugs on non-IEEE platforms
5536 with frexp, ldexp, logb.
5537 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5539 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5540 support, by removing commented-out code and briefly listing the
5541 C89 functions excluded. The commented-out stuff was confusing
5542 maintenance, e.g., we thought we needed cbrt but it was commented out.
5543 (logb): Remove decl; no longer needed.
5544 (isfinite): New macro, if not already supplied.
5545 (isnan): Don't replace any existing macro.
5546 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5547 are present on all C89 platforms.
5548 (Ffrexp): Do not special-case zero, as frexp does the right thing
5550 (Flogb): Do not use logb, as it doesn't have the desired meaning
5551 on hosts that use non-base-2 floating point. Instead, stick with
5552 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5553 frexp, to avoid getting an unspecified result.
5555 * xdisp.c (Qinhibit_debug_on_message): Now static.
5557 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5559 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5560 NSBezierPath (Bug#12131).
5562 2012-09-10 Chong Yidong <cyd@gnu.org>
5564 * fns.c (Fdelq, Fdelete): Doc fix.
5566 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5568 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5569 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5571 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5573 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5574 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5577 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5579 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5580 left fringe if the window has a left margin. This avoids leaving
5581 traces of the cursor because its leftmost pixel is not drawn over.
5583 * dispnew.c (update_window_line): When the left margin area of a
5584 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5585 that screen line. (Bug#12277)
5587 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5589 Assume C89 or later for math functions (Bug#12381).
5590 This simplifies the code, and makes it a bit smaller and faster,
5591 and (most important) makes it easier to clean up signal handling
5592 since we can stop worring about floating-point exceptions in
5593 library code. That was a problem before C89, but the problem
5594 went away many years ago on all practical Emacs targets.
5595 * data.c, image.c, lread.c, print.c:
5596 Don't include <math.h>; no longer needed.
5597 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5598 might be autoconfigured, as that never happens.
5600 * doprnt.c (DBL_MAX_10_EXP):
5601 * print.c (DBL_DIG):
5602 Remove. C89 or later always defines these.
5603 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5604 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5605 (arith_error, domain_error, domain_error2):
5606 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5607 no longer needed -- we simply return what C returns. All uses removed.
5608 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5610 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5611 Remove. All uses expanded, as these macros are no longer used
5612 more than once and are now more trouble than they're worth.
5613 (Ftan): Use tan, not sin / cos.
5614 (Flogb): Assume C89 frexp.
5615 (fmod_float): Assume C89 fmod.
5616 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5617 (init_floatfns): Remove. All uses removed.
5619 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5621 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5622 compositeToPoint for OSX < 10.6 (Bug#12390).
5624 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5626 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5627 This produces more-accurate results.
5629 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5631 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5632 changes (Bug#12088).
5634 2012-09-08 Chong Yidong <cyd@gnu.org>
5636 * syntax.c (Fstring_to_syntax): Doc fix.
5638 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5640 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5641 in the internal border.
5642 (x_set_window_size): Remove static variables and their usage.
5643 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5644 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5645 Remove fringe/internal border adjustment (Bug#11052).
5646 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5647 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5648 (ns_fix_rect_ibw): Remove.
5649 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5650 (ns_dumpglyphs_box_or_relief): Ditto.
5651 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5653 (ns_dumpglyphs_image): Ditto.
5654 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5656 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5657 their usage. Add fringe_extended_p and its use as in other terms.
5658 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5659 scroll bar was removed.
5660 (updateFrameSize): New function.
5661 (windowDidResize): Move code to updateFrameSize and call it.
5663 * nsterm.h (EmacsView): Add updateFrameSize.
5665 2012-09-07 Chong Yidong <cyd@gnu.org>
5667 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5669 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5671 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5673 More signal-handler cleanup (Bug#12327).
5674 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5675 Problem introduced when merging patches. Noted by Eli Zaretskii in
5676 <http://bugs.gnu.org/12327#67>.
5677 * floatfns.c: Comment fix.
5678 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5679 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5680 and anyway the declaration is harmless even if SIGDANGER is not defined.
5681 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5682 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5683 source files not surprisingly expected syssignal.h to define, or
5684 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5685 Include <sys/ioctl.h>, for FIONREAD.
5686 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5687 This eliminates a problem whereby other files mysteriously had
5688 to include "syssignal.h" before including "systty.h" if they
5689 wanted to use "#ifdef SIGIO".
5691 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5693 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5695 * w32.c (sigemptyset): Empty the set.
5696 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5698 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5700 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5702 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5703 (mark_object): Likewise for frame objects.
5705 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5707 * syssignal.h (handle_on_main_thread): Always declare,
5708 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5709 This ports to platforms without HAVE_PTHREAD.
5711 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5713 Signal-handler cleanup (Bug#12327).
5714 Emacs's signal handlers were written in the old 4.2BSD style with
5715 sigblock and sigmask and so forth, and this led to some
5716 inefficiencies and confusion. Rewrite these to use
5717 pthread_sigmask etc. without copying signal sets around. Also,
5718 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5719 'signal', and instead use functions that do not attempt to take
5720 over the system name space. This patch causes Emacs's text
5721 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5722 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5723 Do not include <signal.h> or "syssignal.h", as these
5724 modules do not use signals.
5725 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5726 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5727 Do not include <signal.h>, as "syssignal.h" does that for us now.
5728 * atimer.c (sigmask_atimers): New function.
5729 (block_atimers, unblock_atimers): New functions,
5730 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5732 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5733 no longer needed here.
5734 * emacs.c (main): Inspect existing signal handler with sigaction,
5735 so that there's no need to block and unblock SIGHUP.
5736 * sysdep.c (struct save_signal): New member 'action', replacing
5737 old member 'handler'.
5738 (save_signal_handlers, restore_signal_handlers):
5739 Use sigaction instead of 'signal' to save and restore.
5740 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5741 New function. All users of 'signal' modified to use set_sighandler
5742 if they're writeonly, and to use sys_signal if they're read+write.
5743 (emacs_sigaction_init, forwarded_signal): New functions.
5744 (sys_signal): Remove. All uses replaced by calls to sigaction
5745 and emacs_sigaction_init, or by direct calls to 'signal'.
5746 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5747 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5748 all uses replaced by pthread_sigmask etc. calls.
5749 * syssignal.h: Include <signal.h>.
5750 (emacs_sigaction_init, forwarded_signal): New decls.
5751 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5752 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5753 (sigmask, sys_sigmask): Remove; no longer needed.
5754 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5755 (sigblock, sigunblock, sigfree):
5756 (sigsetmask) [!defined sigsetmask]:
5757 Remove. All uses replaced by pthread_sigmask.
5758 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5759 no longer need to be replaced, and its typical old uses
5760 are now done via emacs_sigaction_init and sigaction.
5761 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5762 (sys_sigdel): Remove; unused.
5763 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5765 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5767 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5768 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5770 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5772 Explicitly mark buffer_defaults and buffer_local_symbols.
5773 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5774 mark_local_symbols here.
5775 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5776 since special buffers aren't marked here any more.
5777 (allocate_buffer): Chain new buffer with all_buffers here...
5778 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5780 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5781 (syms_of_buffer): Remove staticpro of the above.
5782 (init_buffer_once): Set names for buffer_defaults and
5783 buffer_local_symbols.
5785 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5787 Use bool for booleans in font-related modules.
5788 * font.c (font_intern_prop, font_style_to_value)
5789 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5790 (generate_otf_features, font_check_otf_features, font_check_otf)
5791 (font_match_p, font_list_entities, font_at):
5792 * fontset.c (fontset_id_valid_p, reorder_font_vector
5793 (fontset_find_font, Fset_fontset_font)
5794 (face_suitable_for_char_p) [0]:
5795 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5796 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5797 (m17n_flt_initialized, ftfont_shape_by_flt):
5798 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5799 * nsfont.m (nsfont_draw):
5800 * w32font.c (w32font_draw):
5801 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5802 Use bool for booleans.
5803 * font.h: Adjust to above API changes.
5804 (struct font, struct font_driver, struct font_driver_list):
5805 Use bool for booleans.
5806 (struct font): Remove useless member encoding_type.
5808 * fontset.c, xftfont.c: Omit unnecessary static decls.
5810 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5812 * alloc.c (mark_object): Revert window marking code
5813 since it's unsafe for the Fset_window_configuration.
5815 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5817 Fix race conditions with signal handlers and errno (Bug#12327).
5818 Be more systematic about preserving errno whenever a signal
5819 handler returns, even if it's not in the main thread. Do this by
5820 renaming signal handlers to distinguish between signal delivery
5821 and signal handling. All uses changed.
5822 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5823 * data.c (deliver_arith_signal): Rename from arith_error.
5824 * dispnew.c (deliver_window_change_signal): Rename from
5825 window_change_signal.
5826 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5827 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5828 * keyboard.c (deliver_input_available_signal): Rename from
5829 input_available_signal.
5830 (deliver_user_signal): Rename from handle_user_signal.
5831 (deliver_interrupt_signal): Rename from interrupt_signal.
5832 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5833 (deliver_child_signal): Rename from sigchld_handler.
5834 * atimer.c (handle_alarm_signal):
5835 * data.c (handle_arith_signal):
5836 * dispnew.c (handle_window_change_signal):
5837 * emacs.c (handle_fatal_signal, handle_danger_signal):
5838 * keyboard.c (handle_input_available_signal):
5839 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5840 * process.c (handle_pipe_signal, handle_child_signal):
5841 New functions, with the actual signal-handling code taken from the
5842 original respective signal handlers, sans the sporadic attempts to
5843 preserve errno, since that's now done by handle_on_main_thread.
5844 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5845 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5846 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5848 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5849 Move initialization of main_thread to sysdep.c's init_signals.
5850 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5851 our usage, and simplifies the mainline code.
5852 (record_child_status_change): New static function, as a helper
5853 for handle_child_signal, and with most of the old child handler's
5855 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5856 (handle_child_signal): Use the above.
5857 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5858 Moved here from emacs.c.
5859 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5860 code moved here from emacs.c's main function.
5861 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5862 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5863 This lets callers save and restore errno properly.
5865 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5867 Remove redundant or unused things here and there.
5868 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5869 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5870 * editfns.c (Fcompare_buffer_substrings): Likewise.
5871 * frame.h (struct terminal, struct font_driver_list):
5872 Remove redundant declarations.
5873 * window.h (Qleft, Qright): Likewise.
5875 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5877 Do not mark objects from deleted buffers, windows and frames.
5878 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5879 (mark_object): Likewise for windows and frames.
5881 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5883 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5884 buffer_defaults and buffer_local_symbols as valid objects.
5885 Return special value to denote them.
5887 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5889 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5890 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5891 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5892 (file_name_absolute_p, Fsubstitute_in_file_name):
5893 (check_executable, check_writable, Ffile_accessible_directory_p)

5895 (Finsert_file_contents, choose_write_coding_system)
5896 (Fwrite_region, build_annotations, a_write, e_write)
5898 * filelock.c (boot_time_initialized, get_boot_time)
5899 (get_boot_time_1, lock_file_1, within_one_second):
5900 * floatfns.c (in_float):
5901 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5902 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5903 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5904 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5905 * window.c (compare_window_configurations):
5906 Use bool for booleans.
5907 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5908 (Fdefault_file_modes): Now mode_t, not int, for modes.
5909 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5910 (internal_delete_file): Now returns void, not a (boolean) int,
5911 since nobody was looking at the return value.
5912 * lisp.h, window.h: Adjust to above API changes.
5914 * xdisp.c (set_message): Simplify and reindent last change.
5916 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5918 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5920 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5922 * eval.c (call_debugger): Make the function non-static so that we
5923 can call it from set_message.
5925 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5926 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5928 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5930 Give more-useful info on a fatal error (Bug#12328).
5931 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5932 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5933 of doing the work ourselves.
5934 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5935 do most of the work.
5936 (fatal_error_backtrace): New function, taken from the guts
5937 of the old fatal_error_signal, but with a new option to output
5939 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5940 info about the signal than just its number.
5941 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5942 * sysdep.c: Include <execinfo.h>
5943 (emacs_backtrace): New function, taken partly from the previous
5944 code of the 'die' function.
5945 (emacs_abort): Call fatal_error_backtrace rather than abort.
5947 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5949 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5950 eager (load-time) macro-expansion.
5951 * lisp.mk (lisp): Add macroexp.
5953 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5955 Simplify redefinition of 'abort' (Bug#12316).
5956 Do not try to redefine the 'abort' function. Instead, redo
5957 the code so that it calls 'emacs_abort' rather than 'abort'.
5958 This removes the need for the NO_ABORT configure-time macro
5959 and makes it easier to change the abort code to do a backtrace.
5960 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5961 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5962 Remove; sysdep.c's emacs_abort now takes its place.
5963 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5964 'abort' changed to use 'emacs_abort'.
5965 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5966 (abort) [!defined abort]: Rename to ...
5967 (emacs_abort): ... new name.
5968 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5969 the place of the old 'abort' in emacs.c.
5970 * w32.c, w32fns.c (abort): Do not #undef.
5971 * w32.c (emacs_abort): Rename from w32_abort.
5973 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5975 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5976 offsets[j].dv, since the y axis of the screen coordinates points
5977 down, while the y axis of the font definition coordinates points
5978 up. This fixes display of Arabic diacritics such as KASRA and
5979 KASRATAN. (Bug#11860)
5981 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5983 Be more systematic about _setjmp vs setjmp.
5984 * alloc.c (test_setjmp, mark_stack):
5985 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5986 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5987 (png_load, my_error_exit, jpeg_load):
5988 * process.c (send_process_trap, send_process):
5989 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5990 The underscored versions are up to 30x faster on some hosts.
5991 Formerly, the code used setjmp+longjmp sometimes and
5992 _setjmp+_longjmp at other times, with no particular reason to
5993 prefer setjmp+longjmp.
5995 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5997 Fix minor problem found by static checking.
5998 * buffer.c (Fdelete_all_overlays): Return nil.
6000 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6002 * buffer.c (Fdelete_all_overlays): New function.
6004 2012-09-03 Chong Yidong <cyd@gnu.org>
6006 * gtkutil.c: Add extern decl for Qxft.
6008 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6024 EXCLUDE_SUBRS_P. All callers changed.
6025 * dispextern.h, lisp.h: Reflect above API changes.
6026 * firstfile.c (dummy): Use the address of 'main', whose signature
6027 won't change, instead of the address of 'initialize', whose
6028 signature just changed from int to bool.
6029 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6030 * msdos.c (fatal_error_in_progress): ... from here.
6031 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6033 (redisplay_internal, unwind_redisplay): Simply clear
6034 REDISPLAYING_P when unwinding, instead of saving its previous,
6035 always-false value and then restoring it.
6037 Clean up some extern decls.
6038 Mostly, this hoists extern decls out of .c files and into .h files.
6039 That way, we're more likely to catch errors if the interfaces change.
6040 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6041 declare xg_mark_data.
6042 * dispextern.h (x_frame_parm_handlers):
6044 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

6060 * xfont.c (x_clear_errors):
6061 * xterm.c (x_frame_parm_handlers):
6062 Remove now-redundant extern decls.
6063 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6064 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6066 * xfaces.c: Remove unnecessary static decls.
6067 * xterm.c (updating_frame): Remove decl of nonexistent object.
6069 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6070 when building globals.h, as the objects that are not built on
6071 this host are not needed to compile C files on this host.
6073 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6075 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6113 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6115 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

6123 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6125 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6126 more than one grapheme cluster passed to the shaper: compute the
6127 offset adjustment values separately for each cluster. (Bug#11860)
6129 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6130 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6131 about implicit conversions from integer to pointer.
6133 2012-09-01 Daniel Colascione <dancol@dancol.org>
6135 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6136 system used too early.
6138 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6140 Better seed support for (random).

6189 window system declarations.
6191 * frame.h: Move common functions here: set_frame_menubar,
6192 x_set_window_size, x_sync, x_get_focus_frame,
6193 x_set_mouse_position, x_set_mouse_pixel_position,
6194 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6218 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6220 Remove mark_ttys function and fix tty_display_info initialization.
6221 * lisp.h (mark_ttys): Remove prototype.
6222 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6223 to mark_ttys because all possible values of 'top_frame' slot are
6224 the frames which are reachable from Vframe_list.
6225 * term.c (mark_ttys): Remove.
6226 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6228 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

6255 * lread.c (init_lread): For out-of-tree builds, only add the
6256 source directory's site-lisp dir to the load-path if it exists,
6257 consistent with in-tree builds. (Bug#12302)
6259 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6278 Handle click on close button as quit.
6280 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6281 Add window_closed and button_values. Add void as return value for
6282 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6283 Add process_dialog as new member.
6285 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6287 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

6395 * composite.h, lisp.h: Reflect above API changes.
6397 * cmds.c, coding.c: Use bool for booleans.
6398 * cmds.c (move_point, Fself_insert_command):
6399 * coding.h (struct composition status, struct coding_system):
6400 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
6401 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
6402 (emacs_mule_char, decode_coding_emacs_mule)

6416 (Funencodable_char_position, code_convert_region)
6417 (code_convert_string, code_convert_string_norecord)
6418 (Fset_coding_system_priority):
6419 * fileio.c (Finsert_file_contents):
6420 Use bool for booleans.
6421 * coding.h, lisp.h: Reflect above API changes.
6422 * coding.c: Remove unnecessary static function decls.
6423 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6424 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6425 not a boolean 'int', since callers never look at the return value.
6426 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6427 * coding.h (decoding_buffer_size, encoding_buffer_size)
6428 (emacs_mule_string_char): Remove unused extern decls.
6429 (struct iso_2022_spec, struct coding_system):
6430 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6431 (struct emacs_mule_spec): Remove unused field 'full_support'.
6432 All initializations removed.
6433 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6435 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6437 Fix spare memory change (Bug#12286).
6438 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6439 (valid_lisp_object_p): Likewise.
6441 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6443 * window.c (Fset_window_configuration): Record any window's old
6444 buffer if it's replaced (see Bug#8789). If the new current
6445 buffer doesn't appear in the selected window, go to its old
6448 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6450 Special MEM_TYPE_SPARE to denote reserved memory.
6451 * alloc.c (enum mem_type): New memory type.
6452 (refill_memory_reserve): Use new type for spare memory.
6453 This prevents live_cons_p and live_string_p from incorrect
6454 detection of uninitialized objects from spare memory as live.
6456 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6459 * Makefile.in (.PHONY): versioclean -> versionclean.
6461 Remove unused external symbols.
6462 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6463 * window.c (Qwindow_valid_p, decode_valid_window):
6464 Now static, not extern.
6465 * data.c (Qinterval): Remove; unused.
6466 (syms_of_data): Do not define 'interval'.
6467 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6468 * window.h (decode_valid_window):
6471 * character.c, charset.c, chartab.c: Use bool for booleans.
6472 * character.c (lisp_string_width, string_count_byte8)
6473 (string_escape_byte8):
6474 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6475 (load_charset_map_from_file, map_charset_chars)
6476 (Fdefine_charset_internal, define_charset_internal)
6477 (Fdeclare_equiv_charset, find_charsets_in_text)
6478 (Ffind_charset_region, char_charset, Fiso_charset):
6479 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6480 (sub_char_table_set, sub_char_table_set_range)
6481 (char_table_set_range, optimize_sub_char_table)
6482 (map_sub_char_table):
6483 Use bool for boolean.
6484 * character.c (str_to_unibyte): Omit last boolean argument; it was
6485 always 0. All callers changed.
6486 * character.h, charset.h: Adjust to match previous changes.
6487 * character.h (char_printable_p): Remove decl of nonexistent function.
6488 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6489 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6490 are all boolean, so make them single-bit bitfields.
6492 * lisp.h (ASET): Remove attempt to detect side effects.
6493 It was meant to be temporary and it often doesn't work,
6494 because when IDX has side effects the behavior of IDX==IDX
6495 is undefined. See Stefan Monnier in
6496 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6498 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6500 * lisp.h (functionp): New function (extracted from Ffunctionp).
6501 (FUNCTIONP): Use it.
6502 * eval.c (Ffunctionp): Use it.
6504 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6506 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6507 as that's faster and simpler than static storage. Don't bother
6508 with the g_main_context_query overhead if g_main_context_pending
6509 says no events are pending.
6510 (gfds, gfds_size): Remove these static vars.
6511 (xgselect_initialize): Remove; no longer needed.
6512 All uses and decls removed.
6514 * emacs.c (fatal_error_signal_hook): Remove.
6515 All uses removed. This leftover from old code was always 0.
6517 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6518 * casefiddle.c (casify_object, casify_region):
6519 * casetab.c (set_case_table):
6520 * category.c, category.h (word_boundary_p):
6521 * category.h (CHAR_HAS_CATEGORY):
6522 Use bool for booleans, instead of int.
6524 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6526 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6528 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6530 On assertion failure, print backtrace if available.
6531 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6532 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6533 * Makefile.in (LIB_EXECINFO): New macro.
6536 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6537 * bytecode.c (exec_byte_code):
6538 * callint.c (check_mark, Fcall_interactively):
6539 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6540 (getenv_internal, sync_process_alive, call_process_exited):
6541 * lisp.h (USE_SAFE_ALLOCA):
6542 Use bool for booleans, instead of int.
6543 * lisp.h, process.h: Adjust prototypes to match above changes.
6544 * callint.c (Fcall_interactively): Don't assume the mark's
6545 offset fits in 'int'.
6547 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6549 * buffer.c, buffer.h: Use bool for boolean.
6550 * buffer.c (reset_buffer_local_variables)
6551 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6552 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6553 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6554 (overlay_touches_p, overlay_strings, Foverlay_put)
6555 (report_overlay_modification, call_overlay_mod_hooks):
6556 (mmap_enlarge, mmap_set_vars):
6557 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6558 Use bool for booleans, instead of int.
6559 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6560 since the 1-or-0 return value is always ignored anyway.
6561 (mmap_initialized_p):
6562 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6563 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6565 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6567 * bidi.c: Use bool for boolean.
6568 This is a bit more readable, and makes the text segment of bidi.o
6569 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6570 Presumably it's faster too.
6571 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6573 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6574 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6575 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6576 (bidi_explicit_dir_char, bidi_level_of_next_char)
6577 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6578 Use bool for booleans, instead of int.
6579 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6580 (bidi_unshelve_cache): Adjust decls to match code.
6582 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6584 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6587 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6589 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6590 * atimer.h: Include <stdbool.h>.
6592 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6594 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6595 compile time tests instead of run time tests on systems that do
6597 (FRAME_MAC_P): Remove leftover from deleted code.
6598 * frame.c (syms_of_frame): Remove leftover from deleted code.
6600 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6602 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6604 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6606 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6607 Otherwise, the compiler complains about (A?B:C) where B is void
6608 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6609 (fontset_add): Return void, for FONTSET_ADD.
6611 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6613 * alloc.c: Use bool for booleans.
6614 (gc_in_progress, abort_on_gc)
6615 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6616 (dont_register_blocks) [GC_MALLOC_CHECK]:
6617 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6618 (check_string_bytes, make_specified_string, memory_full)
6619 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6620 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6621 (mark_stack, valid_pointer_p, make_pure_string)
6622 (Fgarbage_collect, survives_gc_p, gc_sweep):
6623 Use bool for booleans, instead of int.
6624 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6625 Remove unused local.
6626 * alloc.c (PURE_POINTER_P):
6627 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6628 * editfns.c (Fformat):
6629 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6631 * fns.c (sweep_weak_table):
6632 * lisp.h (suppress_checking, push_message, survives_gc_p)
6633 (make_pure_string, gc_in_progress, abort_on_gc):
6634 * lread.c (readchar, read1):
6635 * print.c (Fprin1_to_string):
6636 * xdisp.c (push_message):
6637 Use bool for booleans affected directly or indirectly by
6640 Make recently-introduced setters macros.
6641 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6642 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6643 (set_fontset_default, set_fontset_fallback): Rename from their
6644 upper-case counterparts, and make them functions rather than macros.
6645 This is more consistent with the other recently-introduced setters.
6646 These don't need to be inline, since they're local.
6648 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6650 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6651 the loop (Bug#12247).
6653 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6655 * lisp.h (vcopy): Use memcpy rather than our own loop.
6656 This fixes a performance regression introduced by the recent
6657 addition of vcopy. This means 'vcopy' will need to be modified
6658 for a copying collector, but that's OK. Also, tighten the
6659 checking in the assertion.
6661 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6663 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6664 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6665 non-base glyph for the width of the base character, according to
6666 what x_draw_composite_glyph_string_foreground expects.
6667 Generate WADJUST value according to composition_gstring_width's
6668 expectations, to produce correct width of the composed character.
6669 Reverse the sign of the DU offset produced by ScriptPlace.
6671 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6673 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6675 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6677 Avoid direct writes to contents member of struct Lisp_Vector.
6678 * lisp.h (vcopy): New function to copy data into vector.
6679 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6680 * fns.c (Ffillarray): Use ASET.
6681 * keyboard.c (timer_check_2): Use AREF and ASET.
6682 (append_tool_bar_item, Frecent_keys): Use vcopy.
6683 * lread.c (read_vector): Use ASET.
6684 * msdos.c (Frecent_doskeys): Use vcopy.
6685 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6686 (Finternal_merge_in_global_face): Use ASET and vcopy.
6687 * xfont.c (xfont_list_pattern): Likewise.
6689 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6691 * window.c (Fwindow_point): For the selected window always return
6692 the position of its buffer's point.
6693 (Fset_window_point): For the selected window always go in its
6694 buffer to the specified position.
6696 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6698 Setter macros for fontsets.
6699 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6700 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6701 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6704 2012-08-20 Glenn Morris <rgm@gnu.org>
6706 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6707 Don't assume that `ln -f' works.
6709 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6711 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6712 and later about non-assignments with no effect. See discussion at
6713 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6716 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6718 Inline setter functions for Lisp_Objects slots of struct specbinding.
6719 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6722 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6724 * window.c (select_window): Always make selected window's buffer
6727 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6729 Use AREF and ASET for docstrings of category tables.
6730 * category.h (CATEGORY_DOCSTRING): Use AREF.
6731 (SET_CATEGORY_DOCSTRING): Use ASET.
6732 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6734 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6736 Inline setter functions for hash table members.
6737 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6738 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6739 (set_hash_key_and_value, set_hash_index, set_hash_next)
6740 (set_hash_hash): New functions.
6741 * charset.c, fns.c: Adjust users.
6743 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6745 Inline getter and setter functions for per-buffer values.
6746 * buffer.h (per_buffer_default, set_per_buffer_default)
6747 (per_buffer_value, set_per_buffer_value): New functions.
6748 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6749 * buffer.c, data.c: Adjust users.
6751 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6753 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6755 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6757 Rely on <config.h> + <unistd.h> to declare 'environ',
6758 as gnulib does this if the system doesn't.
6759 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6760 Remove declaration. MS-Windows declares it on stdlib.h which is
6761 included by conf_post.h.
6762 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6763 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6764 * vm-limit.c: Include <unistd.h>, for 'environ'.
6766 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6767 (start_of_data): Remove decl; mem-limits.h provides it.
6769 * xdisp.c (handle_invisible_prop): Make it a bit faster
6770 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6772 2012-08-19 Chong Yidong <cyd@gnu.org>
6774 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6777 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6779 * .gdbinit: Use call instead of set when calling a function in the
6782 * data.c (set_internal): Don't use set_blv_found.
6783 (Fkill_local_variable): Likewise.
6785 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6787 * nsfont.m (ns_ascii_average_width): Ensure the string
6788 ascii_printable is initialized with a null-terminated character
6789 array. Otherwise, it can contain undesired extra characters.
6791 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6793 port new setting code to Sun C 5.8 2005/10/13
6794 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6795 Return void, not Lisp_Object. Otherwise, the compiler
6796 complains about (A?B:C) where B is void and C is Lisp_Object
6797 when compiling CHAR_TABLE_SET, due to the recent change to
6798 the API of sub_char_table_set_contents.
6800 2012-08-18 Chong Yidong <cyd@gnu.org>
6802 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6803 for the string case (Bug#3874).
6805 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6807 * buffer.h (BSET): Remove (Bug#12215).
6808 Replace all uses with calls to new setter functions.

7740 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when

7742 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.

7744 since it's used in non-static inline functions now.
7746 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

7796 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7798 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7799 This how ASET and AREF are supposed to work, and makes
7800 it easier to think about future improvements. See
7801 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

8184 (w32_kbd_patch_key, key_event): Use the codepage returned by
8185 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
8186 (key_event): use uChar.UnicodeChar only if
8187 w32_console_unicode_input is non-zero.

8214 * alloc.c (listn): Fix the order the arguments are consed onto the
8217 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8218 enumeration constants, as PURE and HEAP are too general, and clash
8219 with other headers and sources, such as gmalloc.c and the
8220 MS-Windows system headers. All users changed.
8222 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8224 Revert last save_excursion_save and save_excursion_restore changes.
8225 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8238 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8239 arms of an 'if', not using conditional expressions; otherwise GDB
8240 complains about the types in the unevaluated arm when the argument
8241 is an integer literal.
8242 (xgetint): Simplify expression.
8243 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8244 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8245 Zaretskii in <http://bugs.gnu.org/12036#13>.
8246 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8247 needed now that we have gdb_make_enums_visible.
8248 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8249 (enum enum_USE_LSB_TAG):
8250 New enum types, packaging up enums that need to be exported to GDB.

8274 * lisp.h (struct Lisp_Excursion): New data type.
8275 (PVEC_EXCURSION): New pseudovector type.
8276 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8277 to deal with it. Adjust comments.

8292 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8293 emacs.c, as this is a more-suitable home. Had this been done earlier
8294 the fix for 12036 would have avoided some of the problems noted in
8295 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8296 would have been more obvious.
8297 * emacs.c: Do not include <verify.h>; no longer needed.
8298 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8299 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8300 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8301 Remove; now done in lisp.h.

8304 (DATA_SEG_BITS): Use it.
8305 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8306 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8307 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8308 not be usable in #if. This simplifies things.
8310 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8312 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8314 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

8317 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8318 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8319 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8320 Adjust to changes in lisp.h and emacs.c, by using
8321 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8322 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8323 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8324 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8325 instead of gdb_valbits.
8326 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8327 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8328 instead of gdb_array_mark_flag.
8329 (xboolvector): Get size from $->size, not $->header.size.
8330 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8331 (xreload, hook-run, hookpost-run): Remove.
8332 * emacs.c: Include <verify.h>.
8333 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8334 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8336 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8337 (gdb_USE_LSB_TAG): New enum constants.
8338 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8339 Also define these as enum constants, so they're visible to GDB.
8340 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8341 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8342 as constants, so they're visible to GDB.
8343 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

8345 Now enum constants, not macros, so they're visible to GDB.
8346 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8347 more convenient now. All uses changed.
8348 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8349 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8351 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8358 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8359 add argument, tune behavior, and adjust all callers.
8361 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8363 Use typedef for EMACS_INT, EMACS_UINT.
8364 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8365 than macros. This simplifies debugging in the usual case, since
8366 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8367 and it allows expressions involving EMACS_INT casts.
8368 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8370 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8380 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8382 Adjust buffer text indirection counters at the end of Fkill_buffer.
8383 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8384 buffer is definitely dead. This should really fix an issue reported
8385 by Christoph Scholtes again. (Bug#12007).
8386 (init_buffer_once): Initialize indirection counters of
8387 buffer_defaults and buffer_local_symbols (for sanity and safety).
8389 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8391 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8392 and continuation glyphs on tooltip frames, leave them at zero.

8395 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8397 Simplify copy_overlay.
8398 * buffer.c (copy_overlay): Simplify. Use build_marker.

8420 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8422 Swap buffer text indirection counters in Fbuffer_swap_text.
8423 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8424 This avoids crash reported by Christoph Scholtes at
8425 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8427 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8429 * nsmenu.m (Popdown_data): New struct.
8430 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8432 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8433 (initWithContentRect): Make imgView and contentView non-static
8434 and autorelease them. Also autorelease img and matrix (Bug#12005).
8435 (dealloc): Remove (Bug#12005).
8437 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8439 Adjust consing_since_gc when objects are explicitly freed.

8452 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8454 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8455 as it's limited by the amount of memory, not by INT_MAX.
8457 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8459 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8460 in special-event-map. See the discussion at

8519 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8520 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8521 Adjust users accordingly.
8522 * font.h (font_open_by_name): Adjust prototype.

8541 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8542 'for_each_per_buffer_object_at'.
8543 All uses changed. It's better to use upper-case for macros that
8544 cannot be implemented as functions, to give the reader a clue
8545 that they're special.
8547 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8549 * alloc.c (Fgarbage_collect): Tweak docstring.

9113 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9114 since nothing has defined it on these platforms.

9130 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9131 function attribute, so we only use it if it exists in the
9134 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9136 Avoid call to strlen in fast_c_string_match_ignore_case.

9183 * s/aix4-2.h (unix): Remove; no longer needed.
9185 EMACS_TIME simplification (Bug#11875).
9186 This replaces macros (which typically do not work in GDB)
9187 with functions, typedefs and enums, making the code easier to debug.
9188 The functional style also makes code easier to read and maintain.
9189 * systime.h: Include <sys/time.h> on all hosts, not just if
9190 WINDOWSNT, since 'struct timeval' is needed in general.
9191 (EMACS_TIME): Now a typedef, not a macro.
9192 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9194 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9198 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9199 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9200 which are not functions. All uses rewritten to use:
9201 (make_emacs_time): New function.
9202 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9203 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9204 not functions. All uses rewritten to use the following, respectively:
9205 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9206 (add_emacs_time, sub_emacs_time): New functions.
9207 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9208 * fileio.c (Fcopy_file):
9209 * xterm.c (XTflash): Get the current time closer to when it's used.
9210 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9224 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9225 (menu_separator_name_p):
9226 * nsmenu.m (ns_update_menubar):
9227 Prefer memcmp to strncmp when either will do.
9228 * nsterm.m: Include <ftoastr.h>.
9230 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9231 Prefer snprintf to strncpy.
9232 * nsterm.m (ns_term_init):
9233 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9234 * nsterm.m (ns_term_init):
9235 Avoid the need for strncpy, by using build_string or
9236 make_unibyte_string directly. Use dtoastr, not snprintf.
9237 * process.c (Fmake_network_process): Diagnose service names that
9238 are too long, rather than silently truncating them or creating
9239 non-null-terminated names.
9240 (Fnetwork_interface_info): Likewise, for interface names.
9241 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9242 Prefer sprintf to strncat.
9243 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9244 Prefer vsnprintf to vsprintf + strncpy.
9246 2012-07-10 Glenn Morris <rgm@gnu.org>
9248 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9249 Clarify fallback case.
9251 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9253 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9254 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9255 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9256 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9257 where argument type is known to be a Lisp_Cons.

9269 Optimize pure C strings initialization.
9270 * lisp.h (make_pure_string): Fix prototype.
9271 (build_pure_c_string): New function, defined as static inline. This
9272 provides a better opportunity to optimize away calls to strlen when
9273 the function is called with compile-time constant argument.
9274 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9275 argument, adjust users accordingly. Use build_pure_c_string where
9277 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9278 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9279 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9281 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9283 Avoid calls to strlen in miscellaneous functions.
9284 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9285 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9286 * lread.c (openp): Likewise.
9288 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9290 Avoid calls to strlen in path processing functions.
9291 * fileio.c (file_name_as_directory): Add comment. Change to add
9292 srclen argument and return the length of result. Adjust users

9296 Adjust users accordingly.
9297 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9299 2012-07-10 Glenn Morris <rgm@gnu.org>
9301 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9306 * s/gnu.h (DATA_START): Move definitions to configure.
9308 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9309 We include usg5-4-common.h, which defines them both.
9311 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9312 O_RDONLY already includes it).
9314 Stop ns builds setting the EMACSLOADPATH environment variable.
9315 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9316 Now it does not set EMACSLOADPATH, just returns the load-path string.
9317 * nsterm.h: Update accordingly.
9318 * lread.c [HAVE_NS]: Include nsterm.h.
9319 (init_lread) [HAVE_NS]: Use ns_load_path.
9320 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9322 2012-07-09 Glenn Morris <rgm@gnu.org>
9324 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9325 since the included bsd-common.h does so.
9327 Stop ns builds setting the EMACSPATH environment variable.
9328 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9329 (ns_init_paths): Do not set EMACSPATH.
9330 * nsterm.h (ns_exec_path): Add it.
9331 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9334 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9336 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9338 * process.c (wait_reading_process_output): 'waitchannels' was unset
9339 when read_kbd || !NILP (wait_for_cell); fix this.
9341 Add GCC-style 'const' attribute to functions that can use it.
9342 * character.h (char_resolve_modifier_mask):
9343 * keyboard.h (make_ctrl_char):
9344 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9345 (init_character_once, next_almost_prime, init_fns, init_image)
9346 (flush_pending_output, init_sound):

9353 Add decls with ATTRIBUTE_CONST.
9355 Minor improvements to make_formatted_string.
9356 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9357 where int is good enough, as vsprintf returns an int.
9358 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9360 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9362 Use make_formatted_string to avoid double length calculation.
9363 * lisp.h (make_formatted_string): New prototype.
9364 * alloc.c (make_formatted_string): New function.
9365 * buffer.c (Fgenerate_new_buffer_name): Use it.

9369 * frame.c (make_terminal_frame, set_term_frame_name)
9370 (x_report_frame_params): Likewise.
9371 * image.c (gs_load): Likewise.
9372 * minibuf.c (get_minibuffer): Likewise.

9387 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9389 Move marker debugging code under MARKER_DEBUG.
9390 * marker.c (MARKER_DEBUG): Move marker debugging code under
9391 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9392 for bootstrap with --enable-checking (~3x slowdown reported
9393 by Juanma Barranquero <lekktu@gmail.com>).
9394 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9396 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9398 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9399 See <http://bugs.gnu.org/11825#29>.
9401 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9403 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9404 has no font, use the frame's font. (Bug#11813)
9405 (display_line): Add commentary about displaying truncation glyphs
9407 (produce_special_glyphs): Move here from term.c.
9409 * term.c (produce_special_glyphs): Move to xdisp.c.
9411 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9414 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9416 * xdisp.c (display_line): Avoid warning about implicit declaration
9419 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9421 * lisp.h: Remove empty conditional.
9423 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9425 * lread.c (load_path_check): Now static.
9427 Fix some minor --with-ns problems found by static checking.
9428 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9429 (x_set_font) [!HAVE_X_WINDOWS]:
9430 * image.c (xpm_load_image) [HAVE_NS]:
9431 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9432 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9433 Remove unused local.
9434 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9435 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9436 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9437 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9438 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9439 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9440 Fix pointer signedness problem.
9441 * xfaces.c (FRAME_X_FONT_TABLE):
9442 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9444 2012-07-07 Glenn Morris <rgm@gnu.org>
9446 * lread.c (load_path_check): New function, split from init_lread.
9447 (init_lread): Reorganize. Motivation:
9448 If EMACSLOADPATH is set, check/warn about that rather than the
9449 defaults, which we are not going to use. Hence we can remove
9450 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9451 Don't warn if site-lisp directories are missing.
9452 If not installed, start from a blank load-path, since
9453 PATH_LOADSEARCH refers to the eventual installation directories.
9455 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9457 Support truncation and continuation glyphs on GUI frames, when
9458 fringes are disabled. (Bug#11832)
9459 * xdisp.c (init_iterator): Get dimensions of truncation and
9460 continuation glyphs even if on GUI frames.
9461 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9462 or both, are absent.
9463 (start_display, move_it_in_display_line_to): Handle the case of a
9464 GUI frame without a fringe to display continuation or truncation
9466 (insert_left_trunc_glyphs): Support GUI frames: make sure
9467 truncation glyphs overwrite enough glyphs from the current line to
9468 have sufficient space in pixels.
9469 (display_line): Support truncation and continuation glyphs on GUI
9470 frames. If some spare pixels are left on the line after inserting
9471 the truncation glyphs, fill that space with a stretch glyph of a
9472 suitably computed width.
9474 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9475 produce_glyphs, to support GUI sessions.
9477 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9479 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9481 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9483 Do not require float-time's arg to fit in time_t (Bug#11825).
9484 This works better on hosts where time_t is unsigned, and where
9485 float-time is applied to the (negative) difference between two times.
9486 * editfns.c (decode_time_components): Last arg is now double *,
9487 not int *, and means to store all the result as a double, without
9488 worrying about whether the seconds part fits in time_t.
9489 All callers changed.
9490 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9491 All callers changed.
9492 (Ffloat_time): Do not fail merely because the specified time falls
9493 outside of time_t range.
9495 2012-07-07 Glenn Morris <rgm@gnu.org>

9522 * w32fns.c (Fx_change_window_property): Doc fix.
9524 * w32fns.c (Fx_window_property): Accept the same arguments as the
9525 X Windows version. Doc fix.

9537 * process.c: Avoid unnecessary calls to gettime.
9538 (wait_reading_process_output): Don't get the time of day
9539 when gobbling data immediately and not waiting, as there's no need
9540 for it in that case. This removes a FIXME.
9542 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9544 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9545 is defined (Bug#11768).

9555 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9557 Compile marker debugging code only if ENABLE_CHECKING is defined.
9558 * marker.c (byte_char_debug_check, count_markers):
9559 Use only if ENABLE_CHECKING is defined.
9560 (byte_debug_flag): Remove.
9561 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9562 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9564 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9566 Avoid code repetition in marker-related functions.
9567 * marker.c (attach_marker): New function.

9586 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9587 * composite.c (autocmp_chars): Likewise.
9588 * editfns.c (buildmark): Remove.
9589 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9590 (save_restriction_save): Use build_marker.
9591 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.

9604 Port to OpenBSD 5.1 amd64.
9605 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9606 This is needed for OpenBSD, and should be harmless on all BSD systems.
9607 Also, include <sys/sysctl.h>, as it should be available on all
9608 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9609 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9610 use p_pid member, not kp_proc.pid.
9612 2012-07-06 Glenn Morris <rgm@gnu.org>
9614 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9616 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9618 More xmalloc and related cleanup.

9627 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9629 Omit needless casts involving void * pointers and allocation.
9630 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9631 as the former is more robust if P's type is changed.
9632 Prefer xzalloc to xmalloc + memset 0.
9633 Simplify malloc-or-realloc to realloc.
9634 Don't worry about xmalloc returning a null pointer.
9635 Prefer xstrdup to xmalloc + strcpy.
9636 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9638 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9639 alloca of a constant.
9641 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9643 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9644 hscroll is larger than the line width. Fixes long and futile
9645 looping inside extend_face_to_end_of_line (on a TTY) producing
9646 glyphs that are not needed and thrown away.
9648 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9650 * marker.c (set_marker_restricted_both): Simplify by using

9664 followed by gtk_box_set_homogeneous (Bug#11768).
9665 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9666 (update_theme_scrollbar_width, xg_create_scroll_bar):
9667 Use gtk_scrollbar_new (Bug#11768).
9668 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9676 * xdisp.c (window_hscroll_limited): New function.
9677 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9678 coordinates when window's hscroll is set to insanely large
9681 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

9750 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9751 This should be fixed in a better way; see Eli Zaretskii in
9752 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9753 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9755 * fileio.c (time_error_value): Rename from special_mtime.
9756 The old name's problems were noted by Eli Zaretskii in
9757 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9759 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9760 This variable's comment says Emacs needs at least one GDB-visible
9761 symbol of type enum pvec_type, to work around GDB problems.
9762 The symbol's value doesn't matter.
9764 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9765 that causes compilation to fail on pre-C99 compilers.
9767 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9769 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9793 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9794 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9795 abusing vector->header.next.nbytes.
9796 (live_vector_p): Use PVEC_TYPE.
9797 (mark_object): Adapt code to extract pvectype. Use switch.
9799 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9801 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9802 Tighten new eassert a bit.
9804 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9806 Fix compilation with --enable-gcc-warnings and -O1
9808 * doprnt.c (doprnt): Change type of tem to int, initialize
9809 to avoid compiler warning. Add eassert.
9810 * search.c (simple_search): Initialize match_byte to avoid
9811 compiler warning. Add eassert.
9813 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9815 Avoid weird behavior with large horizontal scrolls.
9816 Without this change, for example, large hscroll values would
9817 mess up Emacs's display on Fedora 15 x86, presumably due to
9818 overflows in int calculations in the display code.
9819 Also, if buffers had long lines, Emacs would freeze.
9820 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9821 (set_window_hscroll): New function, containing the old guts of
9822 Fset_window_hscroll. Return the clipped value.
9823 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9824 This avoids the need to check against PTRDIFF_MAX.
9826 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.

9835 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9836 since GCC 4.4.6 issues a bogus warning for them.
9838 Fix bugs in file timestamp newness comparisons.
9839 * fileio.c (Ffile_newer_than_file_p):
9840 * lread.c (Fload): Use full timestamp resolution of files,
9841 not just the 1-second resolution, so that files that are only
9842 slightly newer still count as newer.
9843 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9844 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9846 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9848 * fileio.c: Improve handling of file time marker. (Bug#11852)

9855 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9856 marker for non-existing file. (Bug#11852)
9858 2012-07-03 Glenn Morris <rgm@gnu.org>
9860 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9861 and did not make it into globals.h).
9863 2012-07-03 Tom Tromey <tromey@redhat.com>

9903 * lisp.h (Frandom): Make it visible to C.
9904 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new

9926 avoid calls to mallopt if zero_vector is returned.
9928 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9930 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9931 is enabled, avoid dereferencing NULL current_sblock if
9934 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9936 Cleanup basic buffer management.
9937 * buffer.h (struct buffer): Change layout to use generic vector

9950 Lisp area of struct buffer.
9951 (mark_object): Use it. Adjust marking of misc objects
9952 and related comments.
9954 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9956 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9957 wrapper that is not needed because the wrapped code is a no-op (zero
9958 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9959 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9961 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9963 * alloc.c (mark_buffer): Simplify. Remove prototype.
9964 (mark_object): Add comment. Reorganize marking of vector-like
9965 objects. Use CHECK_LIVE for all vector-like objects except buffers
9966 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9967 Avoid redundant calls to mark_vectorlike for bool vectors.
9969 2012-06-30 Glenn Morris <rgm@gnu.org>
9971 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9973 * epaths.in (PATH_SITELOADSEARCH): New.
9974 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9975 This is rather than relying on --enable-locallisppath elements
9976 having "site-lisp" in their names. (Bug#10208#25, 11658)
9978 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9980 * w32proc.c (sys_select): Accept and ignore one more argument.
9982 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9984 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9985 (pselect) [!MS_DOS]: Redirect to sys_select.
9987 * sysdep.c: Don't include dos.h and dosfns.h.
9989 * process.c (sys_select):
9990 * msdos.c (sys_select): Accept one more argument and ignore it.
9992 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9993 adapt data types and code to that.
9996 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9997 which clashes with the gnulib function of the same name.
9999 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10001 * font.c (font_style_to_value, font_style_symbolic)
10002 (font_prop_validate_style): Add type checks for values in
10005 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10007 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10010 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10012 * xdisp.c (try_window_id): Undo last change.
10014 * w32.c (getwd): Adjust commentary about startup_dir.
10015 (init_environment): Always call sys_access, even in non-MSVC
10016 builds. Don't chdir to the directory of the Emacs executable.
10017 This undoes code from 1997 which was justified by the need to
10018 "avoid conflicts when removing and renaming directories". But its
10019 downside was that every relative file name was being interpreted
10020 relative to the directory of the Emacs executable, which can never
10021 be TRT. In particular, it broke sys_access when called with
10022 relative file names.
10023 (sys_access): Map GetLastError to errno.
10025 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10027 * window.h (struct window): Change type of 'fringes_outside_margins'
10028 to bitfield. Fix comment. Adjust users accordingly.
10029 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10031 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10034 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10036 * gnutls.c (emacs_gnutls_handshake):
10037 Add QUIT to make the loop interruptible.
10039 2012-06-29 Glenn Morris <rgm@gnu.org>
10041 * charset.c (init_charset): Make lack of etc/charsets fatal.
10043 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10045 * editfns.c (region_limit): Fix type mismatch.
10047 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10049 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10050 undefined. Convert from xassert to eassert.
10051 * nsmenu.m: Convert from xassert to eassert.
10052 * nsterm.m: Likewise.
10054 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10058 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10060 Avoid integer overflow on scroll-left and scroll-right.
10061 * window.c (HSCROLL_MAX): New macro.
10062 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10063 overflow when requested scroll falls outside ptrdiff_t range.
10065 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10067 * window.h (struct window): Change type of 'hscroll',
10068 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10069 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10070 Adjust users accordingly.
10071 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10072 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10073 from EMACS_INT to ptrdiff_t.
10074 (make_window): Omit redundant initialization.
10076 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

10080 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10082 * window.h (struct window): Change type of 'use_time' and
10083 'sequence_number' from Lisp_Object to int.

10091 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
10092 enabled with --enable-checking=[all,glyphs] configure option.
10093 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10094 adjust comments accordingly.
10095 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
10096 undefined, adjust comments accordingly.

10141 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10143 * alloc.c (allocate_string_data): Remove dead code.
10144 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
10145 avoid GCC warning about unused macro.
10147 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10149 * alloc.c (allocate_string): Omit intervals initialization.
10150 * alloc.c (make_uninit_multibyte_string): Initialize intervals

10173 on Mac OS X Lion: __mod_init_func and __mod_term_func.
10175 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10176 when building with Clang.
10178 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

10182 2012-06-26 Eli Zaretskii <eliz@gnu.org>
10184 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
10185 _stricmp and _strnicmp.
10186 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.

10194 (allocate_frame): Likewise.
10195 * frame.c (make_frame): Omit redundant initialization.
10196 * window.c (make_parent_window): Use memset.
10197 (make_window): Omit redundant initialization.
10198 * process.c (make_process): Omit redundant initialization.

10205 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
10207 * alloc.c: Remove build_string.
10208 * lisp.h: Define build_string as static inline. This provides
10209 a better opportunity to optimize away calls to strlen when the
10210 function is called with compile-time constant argument.
10211 * image.c (imagemagick_error): Convert to build_string.
10212 * w32proc.c (sys_spawnve): Likewise.
10213 * xterm.c (x_term_init): Likewise.
10215 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10217 Use sprintf return value instead of invoking strlen on result.
10218 In the old days this wasn't portable, since some sprintf
10219 implementations returned char *. But they died out years ago and
10220 Emacs already assumes sprintf returns int.
10221 Similarly for float_to_string.
10222 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10223 * ccl.c (ccl_driver):

10227 * print.c (print_object):
10228 * xdisp.c (message_dolog):
10229 * xfns.c (syms_of_xfns):
10230 Use sprintf or float_to_string result to avoid need to call strlen.
10231 * data.c (Fnumber_to_string):
10232 Use make_unibyte_string, since the string must be ASCII.
10233 * lisp.h, print.c (float_to_string): Now returns int length.
10234 * term.c (produce_glyphless_glyph):
10235 Use sprintf result rather than recomputing it.
10237 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10238 * Makefile.in (ALL_CFLAGS):
10239 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10240 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10242 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10244 * dispextern.h (xstrcasecmp): Define to library function
10245 strcasecmp if available.
10246 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10248 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10250 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10263 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10264 sprintf already null-terminates its output.
10266 * xfns.c (x_window): Remove redundant cast.
10268 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10270 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10271 `const char *' to `char *' to avoid compiler warning.
10273 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10275 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10276 instead of truncating it to 63 (admittedly a generous limit).
10278 * process.c: Fix spelling and caps in comments.
10280 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10282 * emacs.c (setpgrp): Remove definition, unused.

10291 * makefile.w32-in (TIMESPEC_H): Remove nt/inc/sys/time.h.
10292 (SYSTIME_H): Add nt/inc/sys/time.h.
10294 * systime.h [WINDOWSNT]: Include sys/time.h.
10296 * s/ms-w32.h (struct timespec): Definition moved from
10297 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

10327 No need for separate decl merely because of _Noreturn.
10328 * sound.c (sound_warning, parse_sound):
10329 Remove unnecessary forward decls.
10331 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10333 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10334 * lisp.h (WAIT_READING_MAX): New macro.
10335 * dispnew.c (Fsleep_for, sit_for):
10336 * keyboard.c (kbd_buffer_get_event):
10337 * process.c (Faccept_process_output):
10338 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10339 This improves on the previous patch, which introduced a bug
10340 when time_t is unsigned and as wide as intmax_t.
10341 See <http://bugs.gnu.org/9000#51>.
10343 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10345 * dispnew.c (sit_for, Fsleep_for):
10346 * keyboard.c (kbd_buffer_get_event):

10359 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10360 Privately reported by Herbert J. Skuhra.
10361 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10363 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10364 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10366 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10368 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10369 last argument of make_unibyte_string.
10371 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10372 language ID in the event parameters.
10374 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10375 event.code, not the obscure "character set ID".
10377 2012-06-23 Chong Yidong <cyd@gnu.org>
10379 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10383 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
10384 * w32.c (fdutimens): New function.
10386 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
10388 * s/ms-w32.h (pselect): Redirect to sys_select.
10390 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
10392 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
10393 in the logic of incrementing and decrementing the value of
10394 use_relocatable_buffers.
10396 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
10398 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.

10401 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
10402 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.

10406 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10408 Support higher-resolution time stamps (Bug#9000).
10409 The time stamps are only nanosecond-resolution at the C level,
10410 since that's the best that any real-world system supports now.
10411 But they are picosecond-resolution at the Lisp level, as that's
10412 easy, and leaves room for future OS improvements.
10414 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10417 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10418 Don't get current time unless it's needed.
10420 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10421 now provides it if it's absent.
10422 (start_atimer): Port to higher-res time stamps.
10423 Check for time stamp overflow. Don't get current time more
10424 often than is needed.
10426 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10427 Include systime.h, not time.h.
10428 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10430 * dired.c: Include stat-time.h.
10431 (Ffile-attributes): File times now have higher resolution.

10454 * fileio.c: Include <stat-time.h>
10455 (Fcopy_file): Copy higher-resolution time stamps.
10456 Prefer to set the time stamp via a file descriptor if that works.

10474 Port to higher-resolution time stamps. Do not assume time_t is signed.
10475 (decode_timer): New function. Timers are now vectors of length 9,
10476 not 8, to accommodate the picosecond component.
10477 (timer_check_2): Use it.
10479 * nsterm.m (select_timeout, timeval_subtract): Remove.
10480 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10481 as they're a bit more accurate and handle overflow better.
10482 (ns_select): Change prototype to be compatible with pselect.
10483 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10484 * nsterm.h (ns_select): Adjust prototype.

10503 (Faccept_process_output, wait_reading_process_output):
10504 Check for time stamp overflow. Do not assume time_t is signed.
10505 (select_wrapper): Remove; we now use pselect.
10506 (Fprocess_attributes): Now generates ns-resolution time stamps.
10508 * sysdep.c: Include utimens.h. Don't include utime.h
10509 or worry about struct utimbuf; gnulib does that for us now.
10510 (gettimeofday): Remove; gnulib provides a substitute.
10511 (make_timeval): New function.
10512 (set_file_times): Now sets ns-resolution time stamps.
10513 New arg FD; all uses changed.

10516 Now returns ns-resolution time stamp. All uses changed.
10517 Check for time stamp overflow.

10520 provides a substitute now.
10522 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10523 since it guarantees struct timespec.
10524 (EMACS_TIME): Now struct timespec, so that we can support
10525 ns-resolution time stamps.
10526 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10527 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10528 (EMACS_USECS): Remove.
10529 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10530 so multiply the arg by 1000 before storing it.

10540 (make_timeval, make_lisp_time, decode_time_components): New decls.
10541 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10542 that it mishandled time_t overflow. You can't compare by subtracting!
10543 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10544 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10546 * term.c: Include <sys/time.h>.

10551 in the undo buffer.
10552 (Fprimitive_undo): Use them when restoring time stamps.

10562 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10563 for compatibility with pselect. Support ns-resolution time stamps.

10567 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10568 Check for time stamp overflow, and support ns-resolution time stamps.

10571 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10572 (timeval_subtract): Remove; no longer needed.
10573 (XTflash, XTring_bell, x_wait_for_event):
10574 Port to ns-resolution time stamps. Don't assume time_t is signed.

10580 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10582 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10583 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10584 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10585 staticidx goes up to 1597 out of 1600 = 0x640.)
10587 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10589 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

10601 access to `contents' member of Lisp_Vector objects with AREF and ASET
10604 2012-06-19 Chong Yidong <cyd@gnu.org>
10606 * frame.c (delete_frame): When selecting a frame on a different
10607 text terminal, do not alter the terminal's top-frame.

10611 (unwind_format_mode_line): Restore them.
10612 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10614 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

10623 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10624 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10625 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10626 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10633 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10635 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10636 gets killed during executing of this function (Bug#11665).
10637 Try to always return Qt when the buffer has been actually killed.
10638 (Vkill_buffer_query_functions): In doc-string say that functions
10639 run by this hook should not change the current buffer.
10641 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10643 Fix recently-introduced process.c problems found by static checking.

10663 * lisp.h (eassert): Assume C89 or later.
10664 This removes the need for CHECK.
10665 (CHECK): Remove. Its comments about always evaluating its
10666 argument were confusing, as 'eassert' typically does not evaluate
10669 * coding.c (produce_chars): Use ptrdiff_t, not int.
10671 * xterm.c (x_draw_underwave): Check for integer overflow.
10672 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10859 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10860 Use an inline function on all platforms when using the union type,
10861 since this is simpler and 'static inline' can be used portably

11003 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11005 * doprnt.c (doprnt): Truncate multibyte char correctly.
11006 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11007 would mishandle a string argument "Xc" if X was a multibyte
11008 character of length 2: it would truncate after X's first byte
11009 rather than including all of X.
11011 2012-06-06 Chong Yidong <cyd@gnu.org>
11013 * buffer.c (word_wrap): Doc fix.

11060 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11062 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11063 Convert pctcpu and pctmem to Lisp float properly.
11064 Let the compiler fold better, as 100.0/0x8000 is exact.
11066 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11068 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11075 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11077 For a 'struct window', replace some Lisp_Object fields to
11078 bitfields where appropriate, remove unused fields.
11079 * window.h (struct window): Remove unused 'last_mark_x' and
11080 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11081 change its type from Lisp_Object to bitfield.
11082 Change type of 'force_start', 'optional_new_start',
11083 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11084 fields from Lisp_Object to bitfield. Adjust users accordingly.
11086 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11088 Pacify gcc -Wdouble-precision when using Xaw.
11089 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11090 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11091 Use 'float' consistently, rather than 'float' in most places
11092 and 'double' in a couple of places.
11094 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11096 * xdisp.c (handle_stop): Detect whether we have overlay strings
11097 loaded by testing it->current.overlay_string_index to be
11098 non-negative, instead of checking whether n_overlay_strings is
11099 positive. (Bug#11587)

11109 * search.c (search_buffer): Remove calls to
11110 r_alloc_inhibit_buffer_relocation, as it is now called by
11111 maybe_unify_char, which was the cause of relocation of buffer text
11114 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11116 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11117 for the duration of call to load_charset, to avoid problems with
11118 callers of maybe_unify_char that access buffer text through C
11121 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11122 decrement the inhibition flag, instead of just setting or
11125 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11127 Remove obsolete '#define static' cruft.
11128 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11129 This #undef was "temporary" in 2000; it is no longer needed
11130 now that '#define static' has gone away.
11131 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11132 (gray_bitmap_bits): Remove; no longer needed.
11133 All uses replaced with definiens.

11141 Define only on platforms that need it.
11142 * emacs.c: Include <sys/gmon.h> when profiling.
11143 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11144 (__executable_start): Remove decl, since lisp.h does it now.
11145 (safe_bcopy): Remove decl; no longer has that name.
11146 (main): Coalesce #if into single bit of code, for simplicity.
11147 Cast pointers to uintptr_t, since standard libraries want integers
11149 * lisp.h (__executable_start): New decl.
11151 2012-05-31 Glenn Morris <rgm@gnu.org>
11153 * image.c (Fimagemagick_types): Doc fix.

11176 Do not create empty overlays with the evaporate property (Bug#9642).
11177 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11178 Bug#9642, but explicitly check that the buffer the overlay would
11179 be moved to is live and rearrange lines to make sure that errors
11180 will not put the overlay in an inconsistent state.
11181 (Fdelete_overlay): Cosmetics.
11183 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11185 * w32term.c (my_bring_window_to_top): New function.
11186 (x_raise_frame): Use handle returned by DeferWindowPos, which
11187 could be different from the original one.

11203 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11205 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11219 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11220 Only r_alloc_inhibit_buffer_relocation needed to be added;
11221 the others were already declared.
11223 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11224 before checking whether it's out of range. Put the check inside
11226 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11228 2012-05-27 Ken Brown <kbrown@cornell.edu>

11240 they are now on lisp.h.
11242 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11244 * search.c (search_buffer): Use it to inhibit relocation of buffer
11245 text while re_search_2 is doing its job, because re_search_2 is
11246 passed C pointers to buffer text. (Bug#11519)
11248 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11249 Update value to 24.
11251 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11252 state after an additional call to move_it_in_display_line_to, keep
11253 the values of it->max_ascent and it->max_descent found for the
11255 (pos_visible_p): Revert the comparison against bottom_y to what it
11256 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11259 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11261 Fix coding-related core dumps with gcc -ftrapv.
11262 The code was computing A - B, where A and B are pointers, and B is
11263 random garbage. This can lead to core dumps on platforms that
11264 have special pointer registers, and it also leads to core dumps on
11265 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11266 A - B only when B is initialized properly.
11267 * coding.c (coding_set_source, coding_set_destination): Return void.
11268 (coding_change_source, coding_change_destinations): New functions,
11269 with the old behaviors of coding_set_source and coding_set_destination.

11280 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11282 * w32console.c: Include window.h.
11283 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11285 (initialize_w32_display): Initialize mouse-highlight data.
11287 * w32inevt.c: Include termchar.h and window.h.
11288 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11289 moves, call note_mouse_highlight. If help_echo changed, call
11290 gen_help_event to produce help-echo message in the echo area.
11291 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11294 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11296 * lread.c (read1): Simplify slightly to avoid an overflow warning
11297 with GCC 4.7.0 on x86-64.
11299 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11301 * bidi.c (bidi_mirror_char): Revert last change: an int is

11312 (make_string_from_bytes, make_specified_string)
11313 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11314 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11316 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11317 (allocate_pseudovector):
11318 Use int, not EMACS_INT, where int is wide enough.
11319 (inhibit_garbage_collection, Fgarbage_collect):
11320 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11321 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11322 int might not be wide enough.
11323 (bidi_cache_search, bidi_cache_find, bidi_init_it)

11340 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11341 (validate_region): Omit unnecessary test for b <= e,
11342 since that's guaranteed by the previous test.
11343 (adjust_overlays_for_delete): Avoid pos + length overflow.
11344 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11345 (report_overlay_modification):
11346 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11347 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11348 Omit pointer cast, which isn't needed anyway, and doesn't work
11349 after the EMACS_INT -> ptrdiff_t change.
11350 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11351 * buffer.h: Adjust decls to match defn changes elsewhere.

11354 Use EMACS_INT, not int, where int might not be wide enough.
11355 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11356 not int, to avoid needless 32-bit limit on 64-bit hosts.
11357 (exec_byte_code): Use tighter memory-full test, one that checks
11358 for alloca overflow. Don't compute the address of the object just
11359 before an array, as that's not portable. Use EMACS_INT, not
11360 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11361 * callint.c (Fcall_interactively):
11362 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11363 * callproc.c (call_process_kill, Fcall_process):
11364 Don't assume pid_t fits into an Emacs fixnum.

11375 (casify_object): Avoid integer overflow when overallocating buffer.
11376 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11377 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11378 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11379 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11380 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

11384 For CCL_MapSingle, check that content and value are in int range.
11385 (ccl_driver, Fregister_code_conversion_map):
11386 Check that Vcode_version_map_vector is a vector.
11387 (resolve_symbol_ccl_program): Check that vector header is in range.
11388 Always copy the vector, so that we can check its contents reliably
11389 now rather than having to recheck each instruction as it's being
11390 executed. Check that vector words fit in 'int'.
11391 (ccl_get_compiled_code, Fregister_ccl_program)
11392 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11393 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

11395 contents are in range.
11396 (Fccl_execute_on_string): Check that status is in range.
11397 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11398 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11399 Accept and return EMACS_INT, not int, because callers can pass values

11406 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11417 Remove now-unnecessary CHECK_NATNUMs.
11418 (Fdefine_charset_internal): Check ranges here, more carefully.
11419 Don't rely on undefined behavior with signed left shift overflow.
11420 Don't assume unsigned int fits into fixnum, or that fixnum fits
11421 into unsigned int. Don't require max_code to be a valid fixnum;
11422 that's not true for gb10830 4-byte on a 32-bit host. Allow
11423 invalid_code to be a cons, for the same reason. Require code_offset
11424 to be a character. Avoid int overflow if max_char is close
11426 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11427 this is intended anyway and avoids some undefined behavior.
11428 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11429 INDEX_TO_CODE_POINT, as that's what it expects.
11430 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11431 * charset.h (DECODE_CHAR): Return int, not unsigned;
11432 this is what was intended anyway, and it avoids undefined behavior.
11433 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11434 integer-overflow issues.
11435 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11436 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11437 where the argument is EMACS_INT, and this behavior is not intended.
11438 * chartab.c (Fmake_char_table, Fset_char_table_range)
11439 (uniprop_get_decoder, uniprop_get_encoder):
11440 Don't assume fixnum fits in int.
11441 * cmds.c (move_point): New function, that does the gist of
11442 Fforward_char and Fbackward_char, but does so while checking
11443 for integer overflow more accurately.
11444 (Fforward_char, Fbackward_char): Use it.
11445 (Fforward_line, Fend_of_line, internal_self_insert)
11446 (internal_self_insert):
11447 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12094 * xterm.c (x_x_to_emacs_modifiers):
12095 Don't assume EMACS_INT overflows nicely into int.
12096 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12097 may come from Lisp.

12106 2012-05-25 Glenn Morris <rgm@gnu.org>
12108 * lisp.mk (lisp): Update for more files being compiled now.
12110 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12112 * lread.c: Remove `read_pure' which makes no difference.
12113 (read_pure): Remove var.
12114 (unreadpure): Remove function.
12115 (readevalloop): Don't call read_list with -1 flag.
12116 (read1, read_vector): Don't test read_pure any more.

12128 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12130 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12133 This directory predates autoconf and is no longer needed nowadays.
12134 Move its few remaining bits of functionality to where they're needed.
12135 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

12138 * Makefile.in (M_FILE): Remove. All uses removed.
12139 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12140 * lisp.h (USE_LSB_TAG):
12141 * mem-limits.h (EXCEEDS_LISP_PTR):
12142 Use VAL_MAX, not VALBITS, in #if.
12143 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12144 (EMACS_UINT): Define unconditionally now.
12145 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12146 (BITS_PER_EMACS_INT): New constants, replacing
12147 what used to be in config.h, but not useful in #if.
12148 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12149 define them any more.
12150 (VAL_MAX): New macro.
12152 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12153 BITS_PER_EMACS_INT, in #if.
12154 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12155 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12156 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:

12158 Move here from removed file m/intel386.h.
12159 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12160 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12162 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12164 Assume C89 or later.
12165 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12166 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)

12187 2012-05-19 Ken Brown <kbrown@cornell.edu>
12189 * xfns.c (x_in_use): Remove `static' qualifier.
12190 * xterm.h (x_in_use): Declare.
12191 * xgselect.c: Include xterm.h.
12192 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12193 and `display_arg' (bug#9754).
12195 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12197 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

12207 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12209 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12210 reference to image_cache->refcount.
12211 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.

12215 * search.c (Fword_search_regexp, Fword_search_backward)
12216 (Fword_search_forward, Fword_search_backward_lax)
12217 (Fword_search_forward_lax): Move functions to isearch.el
12218 (bug#10145, bug#11381).
12220 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12222 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12224 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12226 * lread.c (init_obarray): Declare Qt and Qnil as special.
12228 2012-05-14 Glenn Morris <rgm@gnu.org>
12230 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12231 Put "libexec" before "bin", for the sake of init_callproc_1.
12233 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12235 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12237 * unexaix.c: Port to more-recent AIX compilers.
12238 (report_error, report_error_1, make_hdr, copy_sym)
12239 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12240 Make arguments const char *, not char *, to avoid violations of C
12241 standard and to fix some AIX warnings reported by Gilles Pion.
12243 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12245 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12246 already have overlays loaded.
12247 (handle_single_display_spec): Before returning without displaying
12248 fringe bitmap, synchronize the bidi iterator with the main display
12249 iterator, by calling iterate_out_of_display_property.
12250 (iterate_out_of_display_property): Detect buffer iteration by
12251 testing that it->string is a Lisp string.
12252 (get_next_display_element): When the current object is exhausted,
12253 and there's something on it->stack, call set_iterator_to_next to
12254 proceed with what's on the stack, instead of returning zero.
12255 (set_iterator_to_next): If called at the end of a Lisp string,
12256 proceed to consider_string_end without incrementing string
12257 position. Don't increment display vector index past the end of
12258 the display vector. (Bug#11417)
12259 (pos_visible_p): Don't report a position visible when move_it_to
12260 stopped at the last line of window, which happens to be scanned
12261 backwards by the bidi iteration. (Bug#11464)
12263 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12265 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12266 and right-margin display specs even if the spec is invalid or we
12267 are on a TTY, and thus unable to display on the fringes.
12268 That's because the text with the property will not be displayed anyway,
12269 so we need to signal to the caller that this is a "replacing"
12270 display spec. This fixes display when the spec is invalid or we
12273 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12275 * unexaix.c (make_hdr): Fix typo in prototype.
12276 This bug broke the build on AIX. Problem reported by Gilles Pion.
12278 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12280 * keyboard.c (kbd_buffer_get_event): Read special events also in
12281 batch mode. (Bug#11415)
12283 2012-05-12 Glenn Morris <rgm@gnu.org>
12285 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12287 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12289 * lisp.mk (lisp): Add newcomment.elc.
12291 2012-05-12 Glenn Morris <rgm@gnu.org>
12293 * Makefile.in (MKDIR_P): New, set by configure.
12294 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12296 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12298 Remove unused function hourglass_started.
12299 * dispextern.h (hourglass_started):
12300 * w32fns.c (hourglass_started):
12301 * xdisp.c (hourglass_started): Remove.
12303 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12305 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12306 Update dependencies.
12308 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12310 * xgselect.c (xg_select): Put maxfds+1 into a var.
12311 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12313 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12315 2012-05-10 Dave Abrahams <dave@boostpro.com>
12317 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12318 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12320 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12322 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12323 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12324 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12325 Initialize xd_registered_buses.
12327 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12329 Untag more efficiently if USE_LSB_TAG.
12330 This is based on a proposal by YAMAMOTO Mitsuharu in
12331 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12332 For an admittedly artificial (nth 8000 longlist) benchmark on
12333 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12334 Emacs's overall text size by 1%.
12335 * lisp.h (XUNTAG): New macro.
12336 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12337 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12338 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12339 * eval.c (Fautoload):
12340 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12341 * frame.h (XFRAME): Use XUNTAG.
12343 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12344 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12345 Remove unportable assumptions about print widths of types like
12347 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12348 intptr_t when converting between pointer and integer, to avoid GCC
12349 warnings about wrong width.
12351 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12353 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12354 stack for each reader_thread, instead of defaulting to 8MB
12355 determined by the linker. This avoids failures in creating
12356 subprocesses on Windows 7, see the discussion in this thread:
12357 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12359 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12361 Fix up display of the *Minibuf-0* buffer in the mini window.
12362 * keyboard.c (read_char): Don't clear the echo area if there's no
12364 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12365 contents of *Minibuf-0*) if there's no message displayed in its stead.
12367 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12369 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12372 2012-05-06 Chong Yidong <cyd@gnu.org>
12374 * lisp.mk (lisp): Update.
12376 2012-05-05 Jim Meyering <meyering@redhat.com>
12378 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12380 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12382 * data.c (PUT_ERROR): New macro.
12383 (syms_of_data): Use it. Add new error type `user-error'.
12384 * undo.c (user_error): New function.
12385 (Fprimitive_undo): Use it.
12386 * print.c (print_error_message): Adjust print style for `user-error'.
12387 * keyboard.c (user_error): New function.
12388 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12390 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12392 Do not limit current-time-string to years 1000..9999.
12393 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12394 (Fcurrent_time_string): Support any year that is supported by the
12395 underlying localtime representation. Don't use asctime, as it
12396 has undefined behavior for years outside the range -999..9999.
12398 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12400 Fix race conditions involving setenv, gmtime, localtime, asctime.
12401 Without this fix, interrupts could mess up code that uses these
12402 nonreentrant functions, since setting TZ invalidates existing
12403 tm_zone or tzname values, and since most of these functions return
12404 pointers to static storage.
12405 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12406 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12407 Grow the critical sections to include not just invoking
12408 localtime/gmtime, but also accessing these functions' results
12409 including their tm_zone values if any, and any related TZ setting.
12410 (format_time_string): Last arg is now struct tm *, not struct tm **,
12411 so that the struct tm is saved in the critical section.
12412 All callers changed. Simplify allocation of initial buffer, partly
12413 motivated by the fact that memory allocation needs to be outside
12414 the critical section.
12416 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12418 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12419 with RESET_INTERVAL.
12421 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12422 Remove duplicated buffer name initialization.
12424 2012-05-02 Jim Meyering <jim@meyering.net>
12426 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12428 * xfns.c (x_window): Use xstrdup (Bug#11375).
12430 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12432 * xdisp.c (pos_visible_p): If already at a newline from the
12433 display string before the 'while' loop, don't walk back the glyphs
12434 from it3.glyph_row. Solves assertion violation when the display
12435 string begins with a newline (egg.el). (Bug#11367)
12437 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12439 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12442 2012-05-01 Glenn Morris <rgm@gnu.org>
12444 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12445 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12446 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12447 All were removed before 23.1.
12449 * dispnew.c: Remove HAVE_LIBNCURSES test;
12450 it is always true on relevant platforms.
12452 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12453 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12455 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12457 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12459 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12460 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12463 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12465 Do not avoid creating empty evaporating overlays (Bug#9642).
12466 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12467 That is, do not delete an evaporating overlay if it becomes
12468 empty after its bounds are adjusted to fit within its buffer.
12469 This fix caused other problems, and I'm reverting it until we get
12470 to the bottom of them.
12472 2012-04-27 Chong Yidong <cyd@gnu.org>
12474 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12476 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12478 * xdisp.c (pos_visible_p): If the window start position is beyond
12479 ZV, start the display from buffer beginning. Prevents assertion
12480 violation in init_iterator when the minibuffer window is scrolled
12481 via the scroll bar.
12483 * window.c (window_scroll_pixel_based): Likewise.
12485 2012-04-27 Chong Yidong <cyd@gnu.org>
12487 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12489 2012-04-27 Glenn Morris <rgm@gnu.org>
12491 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12492 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12494 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12496 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12497 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12499 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12501 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12502 display element, check also the underlying string or buffer
12503 character. (Bug#11341)
12505 * w32menu.c: Include w32heap.h.
12506 (add_menu_item): If the call to AppendMenuW (via
12507 unicode_append_menu) fails, disable Unicode menus only if we are
12508 running on Windows 9X/Me.
12510 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12512 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12513 (xgetint): Add missing shift for LSB tags.
12515 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12517 * keyboard.c (read_char): Don't wipe echo area for select window
12518 events: These might get delayed via `mouse-autoselect-window'
12521 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12523 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12524 manipulation of :loaded-from data.
12526 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12528 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12529 now a cons (bug#11311).
12531 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12533 Do not create empty overlays with the evaporate property (Bug#9642).
12534 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12535 if it becomes empty after its bounds are adjusted to fit within
12536 its buffer. Without this fix, in a nonempty buffer (let ((o
12537 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12538 yields an empty overlay that has the evaporate property, which is
12539 not supposed to happen.
12541 Fix minor GTK3 problems found by static checking.
12542 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12543 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12544 (struct _EmacsFixedClass, emacs_fixed_get_type):

12561 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12562 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12563 (__malloc_size_t, __malloc_ptrdiff_t):
12564 Remove. All uses removed, replaced by the definiens if needed,
12565 since we can assume C89 or better now.
12566 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12641 * alloc.c: Handle unusual debugging option combinations.
12642 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
12643 since the two debugging options are incompatible.

12654 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12656 * sysdep.c [__FreeBSD__]: Minor cleanups.
12657 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12658 Use Emacs indenting style more consistently. Avoid some casts.
12659 Use 'double' consistently rather than mixing 'float' and 'double'.
12661 2012-04-21 Eduard Wiebe <usenet@pusto.de>
12663 * sysdep.c (list_system_processes, system_process_attributes):

12670 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12672 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12673 It is never used otherwise.
12675 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12677 * print.c (print_preprocess): Only check print_depth if print-circle
12679 (print_object): Check for cycles even when print-circle is nil and
12680 print-gensym is t, but only check print_depth if print-circle is nil.
12682 2012-04-20 Chong Yidong <cyd@gnu.org>
12684 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12685 set the status to "failed" and ensure that sentinel is run.
12687 2012-04-20 Glenn Morris <rgm@gnu.org>
12689 * process.c (Fset_process_inherit_coding_system_flag)

12698 row, return zero immediately.
12699 (try_cursor_movement): If inside continuation line, don't back up
12700 farther than the first row after the header line, if any.
12701 Don't consider the header-line row as "partially visible", even if

12718 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12719 -Wunused-result, -Wunused-variable. This should go away once
12720 the Emacs and Gnulib regex code is merged.

12742 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12743 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12744 (NEED_MEM_INSERT): New macro.
12745 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12746 Remove one incorrect comment and fix another.

12750 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
12751 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12752 (r_alloc_sbrk): Now static.
12754 Improve ralloc.c interface checking.
12755 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12756 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

12765 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12767 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12768 (struct Lisp_Misc_Any): Likewise.
12769 (struct Lisp_Free): Likewise.

12778 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
12780 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12781 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12782 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12783 * s/netbsd.h, s/sol2-6.h:
12784 Remove definition of GC_MARK_STACK, since the default now works.
12785 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12786 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12787 no longer the default.
12788 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12790 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12792 * lread.c (lisp_file_lexically_bound_p):
12793 Fix hang at ";-*-\n" (bug#11238).
12795 2012-04-14 Eli Zaretskii <eliz@gnu.org>

12802 * nsterm.m (constrainFrameRect): Always constrain when there is only
12803 one screen (Bug#10962).
12805 2012-04-13 Ken Brown <kbrown@cornell.edu>

12813 2012-04-11 Daniel Colascione <dancol@dancol.org>
12815 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12816 against is gone. It's better to use vfork now so that when Cygwin
12817 gains a new, working vfork, we use it automatically (bug#10398).

12834 (force_quit_count): New var.
12835 (handle_interrupt): Use it.
12837 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12839 * w32.c (w32_delayed_load): Record the full path of the library
12840 being loaded (bug#10424).
12842 2012-04-09 Glenn Morris <rgm@gnu.org>
12844 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12845 not just in the obarray, before snarfing them. (Bug#11036)
12847 * Makefile.in ($(leimdir)/leim-list.el):
12848 Pass EMACS rather than BUILT_EMACS.
12850 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12852 * process.c (make_process):
12853 * process.h: Add integer `gnutls_handshakes_tried' member to
12856 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12857 Add convenience `GNUTLS_LOG2i' macro.
12859 * gnutls.c (gnutls_log_function2i): Convenience log function.
12860 (emacs_gnutls_read): Use new log functions,
12861 `gnutls_handshakes_tried' process member, and
12862 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12863 attempts per process (connection).
12865 2012-04-09 Chong Yidong <cyd@gnu.org>
12867 * eval.c (Fuser_variable_p, user_variable_p_eh)

12872 * minibuf.c (Fread_variable): Callers changed.
12874 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12876 * xdisp.c (set_cursor_from_row): If the display string appears in
12877 the buffer at position that is closer to point than the position
12878 after the display string, display the cursor on the first glyph of
12879 the display string. Fixes cursor display when a 'display' text
12880 property immediately follows invisible text. (Bug#11094)
12882 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12884 composite.c: use 'double' consistently
12885 * composite.c (get_composition_id): Use 'double' consistently
12886 instead of converting 'float' to 'double' and vice versa; this is
12887 easier to understand and avoids a GCC warning.
12889 2012-04-09 Glenn Morris <rgm@gnu.org>
12891 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12892 preparation for dumping it with emacs. (Bug#4789)
12893 (leimdir): New variable.
12894 ($(leimdir)/leim-list.el): New rule.
12895 (emacs$(EXEEXT)): Depend on leim-list.el.
12897 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
12898 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
12899 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.

12911 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12913 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12914 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12915 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12916 objects, as mark_maybe_pointer will catch them otherwise.
12917 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12918 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12922 Fix typo that broke non-Windows builds.
12923 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12925 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12927 Support building on MS-Windows with libxml2.
12929 * makefile.w32-in (OBJ2): Add xml.$(O).
12930 (GLOBAL_SOURCES): Add xml.c.
12931 ($(BLD)/xml.$(O)): New dependency list.
12933 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12934 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12935 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12936 [!WINDOWSNT]: New macros.
12937 (init_libxml2_functions, libxml2_loaded_p): New functions.
12938 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12939 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12940 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12941 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12943 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12944 Call init_libxml2_functions before calling libxml2 functions.
12945 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12947 * emacs.c: Don't include libxml/parser.h.
12948 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12949 xmlCleanupParser directly.
12951 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12953 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12955 * indent.c (Fvertical_motion): If there is a display string at
12956 point, use it.vpos to compute how many lines to backtrack after
12957 move_it_to point. (Bug#11133)
12959 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12961 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12962 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12963 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12964 macros related to unification of CJK characters. For the details,
12965 see the discussion following the message here:
12966 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12968 2012-04-04 Chong Yidong <cyd@gnu.org>
12970 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12972 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12974 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12975 instead of alloca. (Bug#11138)
12977 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12979 * w32menu.c (is_simple_dialog): Properly check lisp types.
12982 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12984 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12985 position we get to after a call to move_it_to fails the
12986 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12987 only if we wind up in a string from display property. (Bug#11063)
12989 * window.c (Fdelete_other_windows_internal): Invalidate the row
12990 and column information about mouse highlight, so that redisplay
12991 restores it after reallocating the glyph matrices. (Bug#7464)
12993 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12994 string comes from a `display' text property, use the buffer
12995 position of that property as if we actually saw that position in
12997 (move_it_by_lines): Remove the assertion that
12998 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12999 violated when there's a before-string at the beginning of a line.
13002 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13004 * xdisp.c (append_space_for_newline): If the default face was
13005 remapped, use the remapped face for the appended newline.
13006 (extend_face_to_end_of_line): Use the remapped default face for
13007 extending the face to the end of the line.
13008 (display_line): Call extend_face_to_end_of_line when the default
13009 face was remapped. (Bug#11068)
13011 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13013 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13015 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13017 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13019 2012-03-27 Glenn Morris <rgm@gnu.org>
13021 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13024 2012-03-26 Kenichi Handa <handa@m17n.org>
13026 * dispextern.h (struct glyph): Fix previous change. Change the
13027 bit length of glyphless.ch to 25 (Bug#11082).
13029 2012-03-26 Chong Yidong <cyd@gnu.org>
13031 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13032 (command_loop_1): Use it; inhibit selection update for
13033 handle-select-window too (Bug#8996).
13035 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13037 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13039 2012-03-25 Kenichi Handa <handa@m17n.org>
13041 * dispextern.h (struct glyph): Change the bit length of
13042 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13044 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13046 * s/ms-w32.h (tzname): Include time.h before redirecting to
13047 _tzname. Fixes the MSVC build. (Bug#9960)
13049 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13051 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13054 * xterm.c (XTread_socket): Only modify handling_signal if
13055 !SYNC_INPUT. (Bug#11080)
13057 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13059 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13060 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13061 when fetching a multibyte character consumes more bytes than
13062 CHAR_BYTES returns, due to unification of CJK characters in
13063 string_char. (Bug#11073)
13065 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13067 * process.c (wait_reading_process_output): Handle pty disconnect
13068 by refraining from sending oneself a SIGCHLD (bug#10933).
13070 2012-03-22 Chong Yidong <cyd@gnu.org>

13075 Mark string as coming from a prefix property.
13076 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13077 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13079 2012-03-21 Chong Yidong <cyd@gnu.org>
13081 * xfaces.c (Vface_remapping_alist): Doc fix.
13083 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13085 * w32proc.c (Fw32_set_console_codepage)
13086 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13089 2012-03-20 Chong Yidong <cyd@gnu.org>
13091 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13092 to reflect default non-nil value of redisplay-dont-pause.
13094 2012-03-19 Kenichi Handa <handa@m17n.org>
13096 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13097 it fit in a valid range (Bug#11003).
13099 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13101 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13102 that is not from display property, accept the row as a "cursor
13103 row" if one of the string's character has a non-nil `cursor'
13104 property. Fixes cursor positioning when there are newlines in
13105 overlay strings, e.g. in icomplete.el. (Bug#11035)
13107 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13109 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13111 2012-03-12 Chong Yidong <cyd@gnu.org>
13113 * eval.c (inhibit_lisp_code): Rename from
13114 inhibit_window_configuration_change_hook; move from window.c.
13116 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13117 * window.c (run_window_configuration_change_hook)
13118 (syms_of_window): Callers changed.
13120 2012-03-11 Chong Yidong <cyd@gnu.org>
13122 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13124 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13126 2012-03-10 Chong Yidong <cyd@gnu.org>
13128 * frame.c (other_visible_frames): Don't assume the selected frame
13129 is visible (Bug#10955).
13131 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13133 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13135 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13137 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13138 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13141 2012-03-03 Glenn Morris <rgm@gnu.org>
13143 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13145 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13147 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13148 position past the first glyph_row that ends at ZV. (Bug#10902)
13149 (redisplay_window, next_element_from_string): Fix typos in
13151 (redisplay_window): Pass to move_it_vertically the margin in
13152 pixels, not in screen lines.
13154 2012-03-02 Glenn Morris <rgm@gnu.org>
13156 * buffer.c (buffer-list-update-hook): Doc fix.
13158 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13160 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13161 push_it before setting up the iterator for the first overlay
13162 string, even if we have an empty string loaded.
13163 (next_overlay_string): If there's an empty string on the iterator
13164 stack, pop the stack. (Bug#10903)
13166 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13168 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13169 Suggested by Stefan Monnier in
13170 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13171 * alloc.c (widen_to_Lisp_Object): New static function.
13172 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13173 and widening them to Lisp_Objects. This would work even if
13174 USE_LSB_TAG is defined and wide integers are used, which might
13175 happen in a future version of Emacs.
13177 2012-02-25 Chong Yidong <cyd@gnu.org>
13179 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13182 * xselect.c (Fx_selection_exists_p): Doc fix.
13183 (x_clipboard_manager_save_all): Print an informative message
13184 before saving to clipboard manager.
13186 2012-02-24 Chong Yidong <cyd@gnu.org>
13188 * keyboard.c (process_special_events): Handle all X selection
13189 requests in kbd_buffer, not just the next one (Bug#8869).
13191 2012-02-23 Chong Yidong <cyd@gnu.org>
13193 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13194 call when setting menu-bar-lines and tool-bar-lines parameters.
13195 (unwind_create_frame_1): New helper function.
13197 * window.c (inhibit_window_configuration_change_hook): New var.
13198 (run_window_configuration_change_hook): Obey it.

13208 * fileio.c (Vfile_name_handler_alist): Doc fix.
13210 * buffer.c (Fget_file_buffer): Protect against invalid file
13211 handler return value.

13216 when computing $valmask.
13218 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13219 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13220 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13221 It's useless in that case, and it can cause problems on hosts
13222 that allocate halves of EMACS_INT values separately.
13223 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13224 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13225 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13226 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13227 it avoids undefined behavior on hosts where shifting right by more
13228 than the word width has undefined behavior.
13230 2012-02-19 Chong Yidong <cyd@gnu.org>
13232 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13233 (Funhandled_file_name_directory, Ffile_name_as_directory)
13234 (Fdirectory_file_name, Fexpand_file_name)
13235 (Fsubstitute_in_file_name): Protect against invalid file handler
13236 return values (Bug#10845).
13238 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13240 * .gdbinit (pitx): Fix incorrect references to fields of the
13243 2012-02-17 Chong Yidong <cyd@gnu.org>

13247 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13249 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13250 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13252 2012-02-15 Chong Yidong <cyd@gnu.org>
13254 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13255 marked as special. Also, starting docstrings with * is obsolete.
13257 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13259 * gnutls.c (emacs_gnutls_write): Fix last change.

13268 * keymap.c (Fsingle_key_description): Handle char ranges.
13270 2012-02-12 Chong Yidong <cyd@gnu.org>
13272 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13273 as that creates a dangerous corner case.
13275 * window.c (Fdelete_window_internal): Invalidate the mouse
13276 highlight (Bug#9904).
13278 2012-02-12 Glenn Morris <rgm@gnu.org>
13280 * xselect.c (Fx_own_selection_internal)
13281 (Fx_get_selection_internal, Fx_disown_selection_internal)
13282 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13283 * nsselect.m (Fx_own_selection_internal)
13284 (Fx_disown_selection_internal, Fx_selection_exists_p)
13285 (Fx_selection_owner_p, Fx_get_selection_internal):
13286 Sync docs and argument specs with the xselect.c versions.
13288 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13290 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13292 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13294 * w32select.c (Fx_selection_exists_p): Sync doc string and
13295 argument list with xselect.c. (Bug#10783)

13845 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13846 verifies glyph row's hash code--we have just reallocated the
13847 glyphs, so their contents can be complete garbage. (Bug#10164)

14011 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14012 is set, removing the need for VIRT_ADDRESS_VARIES.
14013 (PURE_P): Use a more-efficient implementation that needs just one
14014 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14015 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14016 to 4 (xorl, subq, cmpq, setbe).
14017 * alloc.c (pure): Always extern now, since that's the

14020 consistency with the new puresize.h.
14021 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14022 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14028 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14029 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14030 behave as if the cursor position were at the window margin.
14032 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14033 and the cursor position is out of bounds, behave as if the cursor
14034 position were at the window margin. (Bug#10075)
14036 2011-11-18 Chong Yidong <cyd@gnu.org>
14038 * window.c (Fwindow_combination_limit): Make first argument

14057 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14059 * xdisp.c (row_hash): New function, body extracted from
14060 compute_line_metrics.
14061 (compute_line_metrics): Call row_hash, instead of computing the
14064 * dispnew.c (verify_row_hash): Call row_hash for computing the
14065 hash code of a row, instead of duplicating code from xdisp.c.
14067 * dispextern.h (row_hash): Add prototype.
14069 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14071 * frame.c (delete_frame): Don't delete the terminal when the last

14107 * xdisp.c (display_line): Move the call to
14108 highlight_trailing_whitespace before the call to
14109 compute_line_metrics, since the latter needs to see the final
14110 faces of all the glyphs to compute ROW's hash value.
14111 Fixes assertion violations in row_equal_p. (Bug#10035)
14113 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

14120 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14121 with user-defined heap size. Bump the default size of the temacs

14125 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14126 current_matrix and desired_matrix. (Bug#9990)
14127 (verify_row_hash) [XASSERTS]: New function.

14172 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14174 Avoid some portability problems by eschewing 'extern inline' functions.
14175 The trivial performance wins aren't worth the portability hassles; see
14176 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14178 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14244 * xmenu.c (cleanup_widget_value_tree): New function.
14245 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14246 calling free_menubar_widget_value_tree directly (Bug#9830).
14248 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14250 Fix some portability problems with 'inline'.
14251 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14252 (window_box_width, window_box_left, window_box_left_offset)
14253 (window_box_right, window_box_right_offset): Declare extern.
14254 Otherwise, these inline functions do not conform to C99 and
14255 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14256 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14257 * intervals.c (adjust_intervals_for_insertion)
14258 (adjust_intervals_for_deletion): Now extern, because otherwise the
14259 extern inline functions 'offset_intervals' couldn't refer to it.
14260 (static_offset_intervals): Remove.
14261 (offset_intervals): Rewrite using the old contents of
14262 static_offset_intervals. The old version didn't conform to C99
14263 because an extern inline function contained a reference to an
14264 identifier with static linkage.
14266 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14268 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14286 (Fwindow_vscroll): Doc fix.
14287 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14288 argument, since it makes no sense to pass a live window and for
14289 consistency with window-child.

14330 official. Move initialization of image_cache_refcount and
14331 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

14371 previous/next-single-property-change returns nil, treat that as
14372 the beginning or the end of the buffer. (Bug#9955)
14374 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14376 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

14408 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14410 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14411 past the beginning of the current glyph matrix.
14413 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14415 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

14499 (w32font_open_internal, compute_metrics):
14500 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14501 instead of calling the "wide" APIs directly.

14514 2011-10-27 Chong Yidong <cyd@gnu.org>
14516 * process.c (make_process): Set gnutls_state to NULL.
14518 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14519 non-NULL, regardless of GNUTLS_INITSTAGE.
14520 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

14568 (bidi_resolve_weak): Don't enter the expensive loop if the current
14569 position is before next_en_pos. Record the bidi type of the first
14570 non-ET, non-BN character we find, in addition to its position.
14571 (bidi_level_of_next_char): Invalidate next_en_type when
14572 next_en_pos is over-stepped.
14574 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14576 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14577 * editfns.c: Rewrite current-time-zone so that it invokes
14578 the equivalent of (format-time-string "%Z") to get the time zone name.
14579 This fixes a bug when the time zone name contains characters that
14580 need converting from the system time locale to Emacs internal format.
14581 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14582 that patch fixed format-time-string to do the conversion, but
14583 I forgot to fix current-time-zone.
14584 (format_time_string): New function, containing most of
14585 what Fformat_time_string used to contain.
14586 (Fformat_time_string): Rewrite in terms of format_time_string.
14587 This doesn't change this function's behavior.
14588 (current-time-zone): Rewrite to use format_time_string.
14589 This fixes the bug reported by Michael Schierl in
14590 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14591 Jason Rumney's 2007-06-07 change worked around this bug, but
14593 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14595 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14597 * xdisp.c (start_display): If the character at POS is displayed
14598 via a display vector, reset IT->current.dpvec_index to zero.
14599 (try_window_reusing_current_matrix): If a line ends in a display
14600 vector or the next line starts in a display vector, continue
14601 redrawing the window even though the character position of
14602 start_row was reached.
14605 2011-10-18 Chong Yidong <cyd@gnu.org>
14607 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14608 with nobreak-char-display too.
14610 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14612 Fix part 3 of bug#9771.
14613 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14614 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14615 non-neutral characters if the current character is a paragraph
14616 separator (a.k.a. Newline). This avoids running the same
14617 expensive loop twice, once when we consume the preceding newline
14618 and the other time when the line actually needs to be displayed.
14619 Avoid the loop when we see neutrals on the base embedding level
14620 following a character whose directionality is the same as the
14621 paragraph's. This avoids running the expensive loop when a line
14622 ends in a long sequence of neutrals, like control characters.
14623 Add assertion against STRONG_AL type. Slightly rearrange code
14624 that determines the type of a neutral given the first non-neutral
14626 (bidi_level_of_next_char): Set next_en_pos to zero when
14627 invalidating its info.
14629 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14631 * xdisp.c (push_display_prop): Determine whether to record string
14632 or buffer position by IT->string, not by IT->method. Allow
14633 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14634 (move_it_vertically_backward): Don't look for character position
14635 immediately after the newline when in a continuation line.
14638 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14640 * window.c (coordinates_in_window): Rewrite and delabelize
14641 vertical border check. (Bug#5357) (Bug#9618)
14643 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14645 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14646 errors in XSetWindowBorder (bug#9310).
14648 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14650 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14651 avoid crash when xmalloc overrun checking is enabled.
14653 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14655 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14656 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14657 cursor motion with <left> and <right> arrow keys.
14659 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14660 some callers set that themselves.
14662 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14664 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14665 display string and the previous row comes from the same string and
14666 is empty. (Bug#9739) (Bug#9738)
14668 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14670 * doc.c (get_doc_string): Encode file name (bug#9735).
14672 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14674 * bidi.c (bidi_level_of_next_char):
14675 * xdisp.c (get_visually_first_element): Remove old incorrect
14676 comments regarding the Unicode Line Separator character.
14678 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14680 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

14683 boundary if nzombies > MAX_ZOMBIES.
14684 * alloc.c (dump_zombies): Add missing format specifier.
14686 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14688 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14689 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14691 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14692 Some packages use them to denote characters with modifiers.
14694 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14696 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14697 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14698 matching a pp-number. Rename parameter var to var1.
14700 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14702 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14704 2011-10-08 Glenn Morris <rgm@gnu.org>
14706 * callint.c (Fcall_interactively): Give a more explicit error for the
14707 'c' case with a non-character input. (Bug#8479)
14709 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14711 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14713 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14714 lines that are hscrolled on the left.
14716 * dispnew.c (buffer_posn_from_coords): Account for a possible
14717 presence of header-line. (Bug#4426)
14719 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14721 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14722 Don't advertise functionality which we discourage or doesn't work.
14724 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14726 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14727 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14728 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14729 this makes Emacs dump core during garbage collection on rare
14730 occasions. sizeof is obviously inferior to offsetof here, so
14731 stick with offsetof.
14732 (GC_POINTER_ALIGNMENT): New macro.
14733 (mark_memory): Omit 3rd (offset) arg; caller changed.
14734 Don't assume EMACS_INT alignment is the same as pointer alignment.
14736 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14738 * keyboard.c (read_key_sequence_remapped): New var.
14739 (read_key_sequence): Compute remapping in the right buffer.
14740 (command_loop_1): Use read_key_sequence's remapping directly.
14742 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14744 * dired.c (file_name_completion): Don't expand file name.
14745 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14746 before checking file name handler.
14748 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14749 they've been requested explicitly (bug#9591).
14751 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14753 * keymap.c (Fsingle_key_description): Use make_specified_string
14754 instead of build_string to build string from push_key_description.
14757 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14759 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14760 This fixes a Y2038 bug on 64-bit hosts.
14761 * buffer.c (reset_buffer):
14762 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14763 (Fclear_buffer_auto_save_failure):
14764 Use 0, not -1, to represent an unset failure time, since time_t
14765 might not be signed.
14767 Remove dependency on glibc malloc internals.
14768 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14769 Move back here from lisp.h, but with their new implementations.
14770 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14771 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14772 * charset.c (charset_table_init): New static var.
14773 (syms_of_charset): Use it instead of xmalloc. This removes a
14774 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14775 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14776 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14777 Move back to alloc.c.
14778 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14779 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14781 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14783 * nsterm.m (windowDidResize): Call x_set_window_size only when
14784 ns_in_resize is true. Otherwise set pixelwidth/height and
14785 call change_frame_size (Bug#9628).
14787 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14789 Port --enable-checking=all to Fedora 14 x86-64.
14790 * charset.c (syms_of_charset): Also account for glibc malloc's
14791 internal overhead when calculating the initial malloc maximum.
14793 Port --enable-checking=all to Fedora 14 x86.
14794 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14796 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14797 (overrun_check_realloc, overrun_check_free):
14798 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14799 That way, xmalloc returns a properly-aligned pointer even if
14800 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14801 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14802 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14803 into account when calculating the initial malloc maximum.
14804 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14805 Move here from alloc.c, so that charset.c can use it too.
14806 Properly align; the old code wasn't right for common 32-bit hosts
14807 when configured with --enable-checking=all.
14808 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14809 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14811 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14813 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14816 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14818 * xdisp.c (compute_display_string_end): If there's no display
14819 string at CHARPOS, return -1.
14821 * bidi.c (bidi_fetch_char): When compute_display_string_end
14822 returns a negative value, treat the character as a normal
14823 character not covered by a display string. (Bug#9624)
14825 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14827 * lread.c (Fread_from_string): Fix typo in docstring.
14829 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14831 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14832 newline, reseat the iterator instead of bidi-iterating there one
14833 character at a time. (Bug#9610)
14834 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14835 TO_CHARPOS if the bidi iterator is at base embedding level.
14837 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14839 * lread.c (readevalloop): Use correct code for NBSP.
14840 (read1): Likewise. (Bug#9608)
14842 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14844 * dbusbind.c (Fdbus_register_signal): When service is not
14845 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14847 2011-09-25 Glenn Morris <rgm@gnu.org>
14849 * buffer.c (truncate-lines): Doc fix.
14851 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14853 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14854 (Fset_window_next_buffers): Doc fix.
14856 2011-09-24 Glenn Morris <rgm@gnu.org>
14858 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14860 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14862 Fix minor problems found by static checking.
14863 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14864 * indent.c (Fvertical_motion): Fix == vs = typo.
14866 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14868 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14869 Default value is now t. Doc fix.
14871 * indent.c (Fvertical_motion): Compute and apply the overshoot
14872 logic when moving up, not only when moving down. Fix the
14873 confusing name and values of the it_overshoot_expected variable;
14874 logic changes accordingly. (Bug#9254) (Bug#9549)
14876 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14877 CHARPOS is covered by a display string which includes newlines.
14878 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14879 is covered by a display string with embedded newlines.
14881 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14883 * dbusbind.c (Fdbus_register_signal): Add match rule to
14884 Vdbus_registered_objects_table. (Bug#9581)
14885 (Fdbus_register_method, Vdbus_registered_objects_table):
14888 2011-09-24 Jim Meyering <meyering@redhat.com>
14890 do not ignore write error for any output size
14891 The previous change was incomplete.
14892 While it makes emacs --batch detect the vast majority of stdout
14893 write failures, errors were still ignored whenever the output size is
14894 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14895 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14896 && echo FAIL: ignored write error
14897 FAIL: ignored write error
14898 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14899 && echo FAIL: ignored write error
14900 FAIL: ignored write error
14901 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14903 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14905 * emacs.c (Fkill_emacs): In noninteractive mode exit
14906 non-successfully if a write error occurred on stdout. (Bug#9574)
14908 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14910 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14913 * dispextern.h (struct it): Update the comment documenting what
14916 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14918 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14919 a display string, extend search for cursor position to end of row.
14920 (find_row_edges): If the row ends in a newline from a display
14921 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14922 Handle the case of a display string with multiple newlines.
14923 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14924 non-empty line. Fixes confusing cursor motion with arrow keys at
14925 the beginning of a line that starts with whitespace.
14927 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14929 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14932 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14934 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14935 boolean (Bug#9154).
14937 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14939 * xdisp.c (display_line): Record maximum and minimum buffer
14940 positions even if no glyphs were produced (e.g., by a zero-width
14941 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14942 buffer positions that will be removed from the glyph row because
14944 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14945 column is beyond frame width: don't subtract 1 "pixel" when
14946 computing width of the stretch.
14947 (reseat_at_next_visible_line_start): Undo the change made on
14948 2011-09-17 that saved paragraph information and restored it after
14949 the call to `reseat'. (Bug#9545)
14951 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14953 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14954 and turn window cursor on if cleared (Bug#9415).
14956 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14958 * search.c (boyer_moore): Take unibyte characters from pattern
14959 literally. (Bug#9458)
14961 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14963 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14965 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14967 Fix minor problem found by static checking.
14968 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14969 initialized, to pacify gcc -Wuninitialized.
14971 * fileio.c: Report proper errno when syscall falls.
14972 (Finsert_file_contents): Save and restore errno,
14973 so that report_file_error outputs the correct diagnostic.
14974 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14976 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14978 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14980 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14982 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14983 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14985 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14987 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14988 about the current paragraph and restore it after the call to reseat.
14990 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14991 (bidi_find_paragraph_start): Search back for paragraph beginning
14992 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14993 (bidi_move_to_visually_next): Only trigger paragraph-related
14994 computations when the last character is a newline or at EOB, not
14995 just any NEUTRAL_B. (Bug#9470)
14997 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14998 truncated lines if point is covered by a display string. (Bug#9524)
15000 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15002 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15003 (cons_to_x_long): New function.
15004 (lisp_data_to_selection_data): Use it. Correct the test for
15005 short-versus-long data; it was negated. Break out of vector
15006 loop, for efficiency, when a long datum is discovered.
15008 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15010 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15012 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15014 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15015 GCC PR/17406) by declaring this function with external scope.
15017 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15019 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15020 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15022 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15024 * editfns.c (Fformat): Correctly handle text properties on "%%".
15026 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15028 * xterm.c (x_draw_composite_glyph_string_foreground):
15029 * w32term.c (x_draw_composite_glyph_string_foreground):
15030 * term.c (encode_terminal_code):
15031 * composite.c (composition_update_it, get_composition_id):
15032 * xdisp.c (get_next_display_element)
15033 (fill_composite_glyph_string): Add comments about special meaning
15034 of TAB characters in a composition.
15036 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15038 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15039 This occurs when processing a multibyte format.
15040 Problem reported by Wolfgang Jenker.
15042 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15044 * xdisp.c (try_cursor_movement): Only check for exact match if
15045 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15047 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15049 Remove unused external symbols.
15050 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15051 * xdisp.c (calc_pixel_width_or_height): Now static.
15052 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15053 * indent.c (check_display_width):
15054 * w32term.c: Fix comment to match code.
15055 * xterm.c, xterm.h (x_catching_errors): Remove.
15057 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15059 * xselect.c: Use signed conversions more consistently (Bug#9498).
15060 (selection_data_to_lisp_data): Assume incoming selection data are
15061 signed integers, not unsigned. This is to be consistent with
15062 outgoing selection data, which was modified to use signed integers
15063 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15064 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15065 expects long, not unsigned long.
15067 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15069 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15070 computation of loop end. Reported by Johan Bockgård
15073 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15075 * frame.c (Fother_visible_frames_p): Function deleted.
15077 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15079 * indent.c (compute_motion): Process display vector front to back
15080 rather than the other way around. (Bug#2496)
15082 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15084 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15086 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15088 * minibuf.c (Fread_from_minibuffer): Doc fix.
15090 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15092 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15093 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15095 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15097 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15098 value for non-existent files.
15100 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15102 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15103 set its "size" to -1. This will set the modtime_size field of
15104 the corresponding buffer to -1, which is what
15105 verify-visited-file-modtime expects for files that do not exist.
15108 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15110 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15112 * lisp.h: ... from here. push_key_description is no longer
15113 defined in keyboard.c, so its declaration should not be in
15114 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15115 logically belongs with push_key_description.
15117 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15119 * buffer.h: Include <sys/types.h> instead of <time.h>.
15120 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15121 Problem reported by Herbert J. Skuhra.
15123 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15125 * xml.c (parse_region): Make the parsing work for
15126 non-comment-starting XML files again (bug#9144).
15128 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15130 * image.c (gif_load): Fix calculation of bottom and right corner.
15133 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15135 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15136 redisplay in small windows.
15138 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15140 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15142 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15144 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15145 Operate on live windows only.
15147 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15149 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15151 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15153 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15154 only under bidi iteration.
15156 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15158 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15160 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15162 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15163 Without this fix, the command to link temacs failed due to an
15164 undefined symbol __builtin_isnan. This is because
15165 /usr/include/iso/math_c99.h #defines isnan(x) to
15166 __builtin_isnan(x), but the bundled gcc, which identifies itself
15167 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15169 * floatfns.c (isnan): #undef, and then #define to a clone of
15171 (Fisnan): Always define, since it's always available now.
15172 (syms_of_floatfns): Always define isnan at the Lisp level.
15174 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15176 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15178 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15180 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15181 The previous code assumed that file offsets (off_t values) fit in
15182 EMACS_INT variables, which is not true on typical 32-bit hosts.
15183 The code messed up by falsely reporting buffer overflow in cases
15184 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15185 when "big" contains more than 2**29 bytes, even though this
15186 inserts just one byte and does not overflow the buffer.
15187 (Finsert_file_contents): Store file offsets as off_t
15188 values, not as EMACS_INT values. Check for overflow when
15189 converting between EMACS_INT and off_t. When checking for
15190 buffer overflow or for overlap, take the offsets into account.
15191 Don't use EMACS_INT for small values where int suffices.
15192 When checking for overlap, fix a typo: ZV was used where
15193 ZV_BYTE was intended.
15194 (Fwrite_region): Don't assume off_t fits into 'long'.
15195 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15197 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15199 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15201 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15203 sprintf-related integer and memory overflow issues (Bug#9412).
15205 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15206 (esprintf, exprintf, evxprintf): New functions.
15207 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15208 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15209 (modify_event_symbol): Do not assume that the length of
15210 name_alist_or_stem is safe to alloca and fits in int.
15211 (Fexecute_extended_command): Likewise for function name and binding.
15212 (Frecursion_depth): Wrap around reliably on integer overflow.
15213 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15214 since some callers pass EMACS_INT values.
15215 (Fsingle_key_description): Don't crash if symbol name contains more
15216 than MAX_ALLOCA bytes.
15217 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15218 (get_minibuffer): Arg is now EMACS_INT, not int.
15219 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15220 (esprintf, exprintf, evxprintf): New decls.
15221 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15223 * dbusbind.c (signature_cat): New function.
15224 (xd_signature, Fdbus_register_signal):
15225 Do not overrun buffer; instead, report string overflow.
15227 * dispnew.c (add_window_display_history): Don't overrun buffer.
15228 Truncate instead; this is OK since it's just a log.
15230 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15231 even if the time zone offset is outlandishly large.
15232 Don't mishandle offset == INT_MIN.
15234 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15235 when creating daemon; the previous buffer-overflow check was incorrect.
15237 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15238 which has the guts of the old verror function.
15240 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15241 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15243 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15244 (font_unparse_xlfd): Don't blindly alloca long strings.
15245 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15246 fits in int, when using sprintf. Use single snprintf to count
15247 length of string rather than counting it via multiple sprintfs;
15248 that's simpler and more reliable.
15249 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15250 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15251 sprintf, in case result does not fit in int.
15253 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15254 (fontset_from_font): Print it.
15256 * frame.c (tty_frame_count): Now printmax_t, not int.
15257 (make_terminal_frame, set_term_frame_name): Print it.
15258 (x_report_frame_params): In X, window IDs are unsigned long,
15259 not signed long, so print them as unsigned.
15260 (validate_x_resource_name): Check for implausibly long names,
15261 and don't assume name length fits in 'int'.
15262 (x_get_resource_string): Don't blindly alloca invocation name;
15263 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15266 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15267 (xg_check_special_colors, xg_set_geometry):
15268 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15270 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15271 Use esprintf, not sprintf, in case result does not fit in int.
15273 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15274 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15275 it as a large positive number.
15276 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15277 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15279 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15280 in case result does not fit in int.
15282 * print.c (float_to_string): Detect width overflow more reliably.
15283 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15284 buffer overrun. Don't assume list length fits in 'int'. Treat
15285 print length of 0 as 0, not as infinity; to be consistent with other
15286 uses of print length in this function. Don't overflow print length
15287 index. Don't assume hash table size fits in 'long', or that
15288 vectorlike size fits in 'unsigned long'.
15290 * process.c (make_process): Use printmax_t, not int, to format
15291 process-name gensyms.
15293 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15295 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15296 to avoid potential buffer overrun.
15298 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15299 if X resource line is longer than 512 bytes.
15301 * xfns.c (x_window): Make sprintf buffer a bit bigger
15302 to avoid potential buffer overrun.
15304 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15306 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15308 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15310 Integer overflow fixes for scrolling, etc.
15311 Without these, Emacs silently mishandles large integers sometimes.
15312 For example, "C-u 4294967297 M-x recenter" was treated as if
15313 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15315 * xdisp.c (try_window_id): Check Emacs fixnum range before
15316 converting to 'int'.
15318 * window.c (window_scroll_line_based, Frecenter):
15319 Check that an Emacs fixnum is in range before assigning it to 'int'.
15320 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15321 values converted from Emacs fixnums.
15322 (Frecenter): Don't wrap around a line count if it is out of 'int'
15323 range; instead, treat it as an extreme value.
15324 (Fset_window_configuration, compare_window_configurations):
15325 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15327 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15328 that can exceed INT_MAX. Check that EMACS_INT value is in range
15329 before assigning it to the (possibly-narrower) index.
15330 (match_limit): Don't assume that a fixnum can fit in 'int'.
15332 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15335 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15336 (Fvertical_motion): Don't wrap around LINES values that don't fit
15337 in 'int'. Instead, treat them as extreme values. This is good
15338 enough for windows, which can't have more than INT_MAX lines anyway.
15340 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15342 * Require libxml/parser.h to avoid compilation warning.
15344 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15346 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15347 since this reportedly can destroy thread storage.
15349 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15351 * syntax.c (find_defun_start): Update all cache variables if
15352 exiting early (Bug#9401).
15354 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15356 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15358 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15359 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15360 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15362 * term.c (tty_append_glyph): New function.
15363 (produce_stretch_glyph): Static function and its prototype deleted.
15365 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15368 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15370 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15371 when checking :margin (Bug#9390).
15372 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15373 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15374 so that the name doesn't mislead. All uses changed.
15376 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15378 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15381 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15383 * xdisp.c (move_it_to): Don't bail out early when reaching
15384 position beyond to_charpos, if we are scanning backwards.
15385 (move_it_vertically_backward): When DY == 0, make sure we get to
15386 the first character in the line after the newline.
15388 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15390 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15391 (ccl_driver): Do not generate an out-of-range pointer.
15392 (Fccl_execute_on_string): Remove unnecessary check for
15393 integer overflow, noted by Stefan Monnier in
15394 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15395 Remove a FIXME that didn't need fixing.
15396 Simplify the newly-introduced buffer reallocation code.
15398 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15400 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15402 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15404 Integer and memory overflow issues (Bug#9196).
15406 * doc.c (get_doc_string): Rework so that
15407 get_doc_string_buffer_size is the actual buffer size, rather than
15408 being 1 less than the actual buffer size; this makes xpalloc more
15411 * image.c (x_allocate_bitmap_record, cache_image):
15412 * xselect.c (Fx_register_dnd_atom):
15413 Simplify previous changes by using xpalloc.
15415 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15416 since either will do and ptrdiff_t is convenient with xpalloc.
15418 * charset.c (charset_table_size)
15419 (struct charset_sort_data.priority): Now ptrdiff_t.
15420 (charset_compare): Don't overflow if priorities differ greatly.
15421 (Fsort_charsets): Don't assume list length fits in int.
15422 Check for size-calculation overflow when allocating sort data.
15423 (syms_of_charset): Allocate an initial charset table that is
15424 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15426 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15428 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15429 The actual value is always <= INT_MAX, and leaving it unsigned made
15430 overflow checking harder.
15432 * dispextern.h (struct glyph_matrix.rows_allocated)
15433 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15434 with xpalloc. The values are still always <= INT_MAX.
15436 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15438 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15439 (SAFE_NALLOCA): New macro.
15441 * region-cache.c (struct boundary.pos, find_cache_boundary)
15442 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15443 (set_cache_region, invalidate_region_cache)
15444 (revalidate_region_cache, know_region_cache, region_cache_forward)
15445 (region_cache_backward, pp_cache):
15446 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15447 so that ptrdiff_t * can be passed to xpalloc.
15448 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15449 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15450 (pp_cache): Don't assume cache_len fits in int.
15451 * region-cache.h: Adjust extern decls to match.
15453 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15454 EMACS_INT, since either will do, for xpalloc.
15456 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15457 (xnmalloc, xnrealloc, xpalloc): New functions.
15459 * bidi.c (bidi_shelve_header_size): New constant.
15460 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15461 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15463 * bidi.c (bidi_cache_shrink):
15464 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15466 Don't update size of array until after memory allocation succeeds,
15467 because xmalloc/xrealloc may not return.
15468 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15469 now that we have proper integer overflow checking.
15470 (record_overlay_string, overlay_strings): Catch overflows when
15471 calculating size of overlay_str_buf.
15473 * callproc.c (Fcall_process): Check for size overflow when
15474 calculating size of args2.
15475 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15476 Normally we prefer signed values, but sticking with ptrdiff_t would
15477 require adding more-complicated checks.
15479 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15480 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15481 Redo buffer-overflow calculations to avoid integer overflow.
15482 Add a FIXME comment where memory seems to be over-allocated.
15484 * character.c (Fstring): Check for size-calculation overflow.
15486 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15487 unnecessary integer overflow. Check for size overflow.
15488 (encode_coding_object): Don't update size until xmalloc succeeds.
15490 * composite.c (get_composition_id): Check for overflow in glyph
15491 length calculations.
15493 Integer and memory overflow fixes for display code.
15494 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15495 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15496 (scrolling_window): Check for overflow in size calculations.
15497 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15498 Don't assume glyph table len fits in int.

15500 (row_table_size): Now ptrdiff_t, not int.
15501 (scrolling_window): Avoid overflow in size calculations.
15502 Don't update size until allocation succeeds.
15503 * fns.c (concat): Check for overflow in size calculations.
15504 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15505 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15506 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15508 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15509 (get_doc_string): Check for size calculation overflow.
15510 Don't update size until allocation succeeds.
15511 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15512 EMACS_INT, where ptrdiff_t will do.
15513 (Fsubstitute_command_keys): Check for string overflow.
15515 * editfns.c (set_time_zone_rule): Don't assume environment length
15517 (message_length): Now ptrdiff_t, not int.
15518 (Fmessage_box): Don't update size until allocation succeeds.
15519 Don't assume message length fits in int.
15520 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15522 * emacs.c (main): Do not reallocate argv, since there is a null at
15523 the end that can be overwritten, and this way there's no need to
15524 worry about size-calculation overflow.
15525 (sort_args): Check for size-calculation overflow.
15527 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15529 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15531 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15532 (x_set_scroll_bar_width, x_figure_window_size):
15533 Check for integer overflow.
15534 (x_set_alpha): Do not assume XINT fits in int.
15536 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15537 This is for the members text_lines, text_cols, total_lines, total_cols,
15538 where the system imposes an 'int' limit.
15540 * fringe.c (Fdefine_fringe_bitmap):
15541 Don't update size until alloc works.
15543 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15544 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15546 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15547 Check for size-calculation overflow.
15548 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15549 do, as we prefer signed integers.
15550 (id_to_widget.max_size, id_to_widget.used)
15551 (xg_store_widget_in_map, xg_remove_widget_from_map)
15552 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15553 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15554 Use and return ptrdiff_t, not int.
15555 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15556 * gtkutil.h: Change prototypes to match the above.
15558 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15559 are duplicate now that they've been promoted to lisp.h.
15560 (x_allocate_bitmap_record, x_alloc_image_color)
15561 (make_image_cache, cache_image, xpm_load):
15562 Don't update size until alloc is done.
15563 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15565 Check for size calculation overflow.
15566 (ct_colors_allocated_max): New constant.
15567 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15570 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15571 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15572 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15573 Use ptrdiff_t, not int, to count maps.
15574 (read_char_minibuf_menu_prompt): Check for overflow in size
15575 calculations. Don't update size until allocation succeeds.
15576 Redo calculations to avoid overflow.
15577 * keyboard.h: Change prototypes to match the above.
15579 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15581 (current_minor_maps): Check for size calculation overflow.
15582 * keymap.h: Change prototypes to match the above.
15584 * lread.c (read1, init_obarray): Don't update size until alloc done.
15586 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15587 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15589 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15590 Now ptrdiff_t, not int.
15591 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15603 (Fset_match_data): Don't assume list lengths fit in 'int'.
15605 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15606 for command line length. Do not attempt to address one before the
15607 beginning of an array, as that's not portable.
15609 * term.c (max_frame_lines): Remove; unused.
15610 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15612 (encode_terminal_code, calculate_costs): Check for size
15613 calculation overflow.

15617 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15619 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15620 subtracting pointers.

15635 Use ptrdiff_t, not int, for sizes.
15636 (Finternal_make_lisp_face, cache_face):
15637 Check for size calculation overflow.
15638 (cache_face): Treat size calculation overflows as if they were
15639 memory exhaustion (the usual treatment), rather than aborting.
15641 * xfns.c (x_encode_text, x_set_name_internal)
15642 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15643 sizes, since they can exceed INT_MAX in size. Check for size
15644 calculation overflow.
15646 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15647 (xg_select): Check for size calculation overflow.
15648 Don't update size until alloc done.
15650 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15651 as sprintf is limited to int lengths.
15653 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15654 (X_LONG_MIN): New macros.
15655 Use them to make the following changes clearer.
15656 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15657 This change doesn't affect the value now, but it may help remind
15658 future maintainers not to raise the value too much later.
15659 (SELECTION_QUANTUM): Remove, replacing with ...
15660 (selection_quantum): ... new function, which avoids overflow.
15662 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15663 assumption that selection length fits in 'int'.
15664 (x_reply_selection_request, x_handle_selection_request)
15665 (x_get_window_property, receive_incremental_selection)
15666 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15667 (lisp_data_to_selection_data, clean_local_selection_data):

15670 (receive_incremental_selection, x_property_data_to_lisp):
15671 Redo calculations to avoid overflow.
15672 (x_reply_selection_request): When sending hint, ceiling it at
15673 X_LONG_MAX rather than relying on wraparound overflow to send

15676 (lisp_data_to_selection_data, x_property_data_to_lisp):
15677 Check for size-calculation overflow.
15678 (x_get_window_property, receive_incremental_selection)

15680 Don't store size until memory allocation succeeds.
15681 (x_get_window_property): Plug memory leak on memory exhaustion.
15682 Don't double-block input; malloc is safe here. Don't assume 2**34
15683 - 4 fits in unsigned long. Add an xassert to check
15684 XGetWindowProperty overflow. Be more careful about overflow
15685 calculations, and distinguish size from memory overflow better.
15686 (receive_incremental_selection): When tracing, don't assume
15687 unsigned int is less than INT_MAX.
15688 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15689 harmful) conversions of unsigned short to int.
15690 (lisp_data_to_selection_data): Don't assume that integers
15691 in the range -65535 through -1 fit in an X unsigned short.
15692 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15693 result parameters unless successful. Rely on cons_to_unsigned
15694 to report problems with elements; the old code wasn't right anyway.
15695 (x_check_property_data): Check for int overflow; we cannot use
15696 a wider type due to X limits.
15697 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15699 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15701 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)

15729 * lisp.h (hash_lookup, hash_put):
15730 * minibuf.c (Ftest_completion):
15731 Use ptrdiff_t for hash table indexes, not int (which is too
15732 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15733 32-bit --with-wide-int hosts).
15735 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15736 Add a FIXME comment about memory leaks.
15737 (syms_of_charset): Don't assume xmalloc returns.

15744 with outlandish widths.
15745 * character.h (sanitize_tab_width): Rename from sanitize_width,
15746 now that we have two such functions. All uses changed.

15758 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15760 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

15764 * xterm.c: Don't go over XClientMessageEvent limit.
15765 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15766 (x_send_scroll_bar_event): Likewise. Check that the size does not
15767 exceed limits imposed by XClientMessageEvent, as well as the usual
15768 ptrdiff_t and size_t limits.
15770 * keyboard.c: Overflow, signedness and related fixes.
15771 (make_lispy_movement): Use same integer type in forward decl
15772 that is used in the definition.
15773 (read_key_sequence, keyremap_step):
15774 Change bufsize argument back to int, undoing my 2011-03-30 change.
15775 We prefer signed types, and int is wide enough here.
15776 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15777 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15778 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15779 length, not size_t. Use ptrdiff_t for index, not int.
15780 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15781 possibility of integer overflow.
15783 Overflow, signedness and related fixes for images.
15785 * dispextern.h (struct it.stack[0].u.image.image_id)

15805 (lookup_image): Remove unnecessary tests.
15806 (xbm_image_p): Locals are now of int, not EMACS_INT,
15807 since parse_image_check makes sure they fit into int.
15808 (png_load, gif_load, svg_load_image):
15809 Prefer int to unsigned where either will do.
15810 (tiff_handler): New function, combining the cores of the
15811 old tiff_error_handler and tiff_warning_handler.
15812 This function is rewritten to use vsnprintf and thereby avoid
15813 stack buffer overflows. It uses only the features of vsnprintf
15814 that are common to both POSIX and native Microsoft.
15815 (tiff_error_handler, tiff_warning_handler): Use it.
15816 (tiff_load, gif_load, imagemagick_load_image):
15817 Don't assume :index value fits in 'int'.
15818 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15819 (imagemagick_load_image): Check that crop parameters fit into
15820 the integer types that MagickCropImage accepts. Don't assume
15821 Vimagemagick_render_type has a nonnegative value. Don't assume
15822 size_t fits in 'long'.
15823 (gs_load): Use printmax_t to print the widest integers possible.
15824 Check for integer overflow when computing image height and width.

15836 handle_single_display_spec, not just 1 or zero.
15837 (handle_single_display_spec): If the display spec is of the form
15838 `(space ...)', and specifies display in the text area, return 2
15840 (try_cursor_movement): Check for the need to scroll more
15841 accurately, and prefer exact match for point under bidi.
15842 Don't advance `row' beyond the last row of the window.
15844 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15845 into disp_prop; all users changed.

15859 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15860 buffers, return left-to-right.
15861 (set_cursor_from_row): Consider candidate row a win if its glyph
15862 represents a newline and point is on that newline. Fixes cursor
15863 positioning on the newline at EOL of R2L text within L2R
15864 paragraph, and vice versa.
15865 (try_cursor_movement): Check continued rows, in addition to
15866 continuation rows. Fixes unwarranted scroll when point enters a
15867 continued line of R2L text within an L2R paragraph, or vice versa.
15868 (cursor_row_p): Consider the case of point being equal to
15869 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15870 from the end of a short line to the beginning of a continued line
15871 of R2L text within L2R paragraph.

15898 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15899 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15900 candidate is selected by the mouse, and that candidate has a
15901 composed character under the mouse.
15903 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15904 coordinates reported by pos-visible-in-window-p for a composed
15905 character in column zero.
15907 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15913 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15914 consider it a hit if to_charpos is anywhere in the range of the
15915 composed buffer positions.
15917 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15919 * image.c (gif_load): Don't assume that each subimage has the same
15920 dimensions as the base image. Handle disposal method that is
15921 "undefined" by the gif spec (Bug#9335).
15923 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15925 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15931 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15932 from an Org mode buffer to a Speedbar frame.
15934 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15935 a composition, take its buffer position from IT->cmp_it.charpos.
15936 Fixes cursor positioning at the beginning of a line that begins
15937 with a composed character.
15939 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15941 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15942 character bidirectional type, use STRONG_L instead. Fixes crashes
15943 in a buffer produced by `describe-categories'.
15945 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15946 members before the level stack, so they would be saved and
15947 restored when copying iterator state. Fixes incorrect reordering
15948 around TABs covered by display properties.

15976 Fix memory allocation problems in Cygwin build (Bug#9273).
15978 * unexcw.c ( __malloc_initialized): Declare external variable.
15979 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15981 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15983 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16022 * xdisp.c (move_it_in_display_line_to): Don't invoke
16023 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16024 ppos_it. Fixes vertical cursor motion when line beginning is
16025 covered by an image. (Bug#9296)
16027 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>

16036 the event loop. Get status from as_status (Bug#7276).
16038 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16039 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16040 the event loop (Bug#7276).
16042 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16044 * gnutls.c (QCgnutls_bootprop_priority)
16045 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16046 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16047 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16048 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16049 (QCgnutls_bootprop_verify_hostname_error)
16050 (QCgnutls_bootprop_callbacks_verify): Rename from
16051 Qgnutls_bootprop_..., all uses changed.
16053 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16056 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16058 * xfaces.c (Qframe_set_background_mode): Now static.
16059 * dispextern.h (Qframe_set_background_mode): Remove decl.
16061 * process.c (Fnetwork_interface_info): Declare local only if needed.
16063 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16065 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16066 (Fnetwork_interface_list): Allocate in increments of bytes instead
16067 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16068 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16070 (struct ifflag_def): notrailers is smart on OSX.
16071 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16072 Get hardware address with getifaddrs if available.
16074 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16076 * xdisp.c (iterate_out_of_display_property): xassert that
16077 IT->position is set to within IT->object's boundaries. Break from
16078 the loop as soon as EOB is reached; avoids infloops in redisplay
16079 when IT->position is set up wrongly due to some bug.
16080 Set IT->current to match the bidi iterator unconditionally.
16081 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16082 entry. Force push_it to save on the stack the current
16083 buffer/string position, to be restored by pop_it. Fix flags in
16084 the iterator structure wrt the object coming from a display
16085 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16086 properties. (Bug#9284)
16088 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16090 * fontset.c (fontset_get_font_group): Add proper type checks.
16093 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16095 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16096 and LC_VERSION_MIN_MACOSX.
16097 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16098 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16100 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16102 * xdisp.c (forward_to_next_line_start): Allow to use the
16103 no-display-properties-and-no-overlays under bidi display.
16104 Set disp_pos in the bidi iterator to avoid searches for display
16105 properties and overlays.
16107 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16109 * editfns.c (Fset_time_zone_rule): Document relationship with the
16112 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16113 the font entity extracted from the cache (Bug#8109).
16115 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16117 * composite.c (autocmp_chars): Don't reset point. That is done by
16118 restore_point_unwind (Bug#5984).
16120 2011-08-07 Juri Linkov <juri@jurta.org>
16122 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16123 to show the arg `TIME' instead of `TIMEVAL'.
16125 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16127 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16128 display property strides EOL and includes a newline, as in
16129 longlines-mode. (Bug#9254)
16130 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16131 word-wrap under bidirectional display. (Bug#9224)
16133 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16134 is non-zero, even if the data buffer is NULL. Fixes a crash in
16135 vertical-motion with longlines-mode. (Bug#9254)
16137 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16139 * bidi.c <bidi_cache_total_alloc>: Now static.
16140 (bidi_initialize): Initialize bidi_cache_total_alloc.
16142 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16145 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16146 amount allocated this far in `bidi_cache_total_alloc'.
16147 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16148 non-zero, only free the data buffer without restoring the cache
16149 contents. All callers changed.
16151 * dispextern.h (bidi_unshelve_cache): Update prototype.
16153 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16154 (move_it_in_display_line, move_it_to)
16155 (move_it_vertically_backward, move_it_by_lines): Replace the call
16156 to xfree to an equivalent call to bidi_unshelve_cache.
16157 (move_it_in_display_line_to): Fix logic of returning
16158 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16160 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16162 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16163 came from a string character with a `cursor' property. (Bug#9229)
16165 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16167 * Makefile.in (LIB_PTHREAD): New variable.
16168 (LIBES): Add LIB_PTHREAD (Bug#9216).
16170 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16171 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16173 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16175 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16177 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16179 * xterm.c (x_find_topmost_parent): New function.
16180 (x_set_frame_alpha): Find topmost parent window with
16181 x_find_topmost_parent and set the property there also (bug#9181).
16182 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16184 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16186 * callproc.c (Fcall_process): Avoid vfork clobbering
16187 the local vars buffer, coding_systems, current_dir.
16189 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16191 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16193 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16195 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16196 so that it is not optimized away.
16198 * xdisp.c (compute_display_string_pos): Remove unused local.
16200 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16202 Fix slow cursor motion and scrolling in large buffers with
16203 selective display, like Org Mode buffers. (Bug#9218)
16205 * dispextern.h (struct bidi_it): New member disp_prop_p.
16207 * xdisp.c: Remove one-slot cache of display string positions.
16208 (compute_display_string_pos): Accept an additional argument
16209 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16210 for a display string or property. If found, set DISP_PROP_P
16213 * bidi.c (bidi_fetch_char): Accept an additional argument
16214 DISP_PROP_P, and pass it to compute_display_string_pos.
16215 Only handle text covered by a display string if DISP_PROP_P is returned
16216 non-zero. All callers of bidi_fetch_char changed.
16218 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16220 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16222 2010-12-03 Don March <don@ohspite.net>
16224 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16225 last character M-[char] is translated to ESC [char] (bug#7541).
16227 2011-08-02 Kenichi Handa <handa@m17n.org>
16229 * lisp.h (uniprop_table): Extern it.
16231 * chartab.c (uniprop_table): Make it non-static.
16233 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16235 * xdisp.c (forward_to_next_line_start): Accept additional argument
16236 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16238 (reseat_at_next_visible_line_start): Use the bidi iterator state
16239 returned by forward_to_next_line_start to restore the state of
16240 it->bidi_it after backing up to previous newline. (Bug#9212)
16242 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16244 * regex.c (re_comp): Protoize.
16245 (re_exec): Fix return type.
16246 (regexec): Fix type of `ret'. (Bug#9203)
16248 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16250 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16251 This is needed if max-image-size is a floating-point number.
16253 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16255 * print.c (print_object): Print empty symbol as ##.
16257 * lread.c (read1): Read ## as empty symbol.
16259 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16261 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16262 setting frame foreground color (Bug#9175).
16263 (x_set_background_color): Likewise.
16265 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16266 contents (Bug#9176).
16267 (EmacsTooltip -init): Remove bezels and add shadows to
16270 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16271 or scroll bar (Bug#8470).
16273 * nsfont.m (nsfont_open): Remove assignment to voffset and
16274 unnecessary vars hshink, expand, hd, full_height, min_height.
16275 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16277 * nsterm.h (nsfont_info): Remove voffset field.
16279 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16281 Implement strike-through and overline on NextStep (Bug#8863).
16283 * nsfont.m (nsfont_open): Use underline position provided by font,
16284 instead of hard-coded value of 2.
16285 (nsfont_draw): Call ns_draw_text_decoration instead.
16287 * nsterm.h: Add declaration for ns_draw_text_decoration.
16289 * nsterm.m (ns_draw_text_decoration): New function for drawing
16290 underline, overline, and strike-through.
16291 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16292 ns_draw_text_decoration. Change treatment of cursor drawing to
16293 accommodate underlining, etc.
16295 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16297 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16300 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16302 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16303 Without this fix, if a signal arrives just after memory fills up,
16304 'malloc' might be invoked reentrantly.
16306 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16307 In other words, assume that every image size is allowed, on non-X
16308 hosts. This assumption is probably wrong, but it lets Emacs compile.
16310 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16312 * regex.c (re_iswctype): Convert return values to boolean.
16314 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16316 * xdisp.c (compute_display_string_pos): Don't use cached display
16317 string position if the buffer had its restriction changed.
16320 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16322 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16324 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16326 Integer signedness and overflow and related fixes. (Bug#9079)
16328 * bidi.c: Integer size and overflow fixes.
16329 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16330 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16331 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16332 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16333 (bidi_find_other_level_edge):
16334 Use ptrdiff_t instead of EMACS_INT where either will do.
16335 This works better on 32-bit hosts configured --with-wide-int.
16336 (bidi_cache_ensure_space): Check for size-calculation overflow.
16337 Use % rather than repeated addition, for better worst-case speed.
16338 Don't set bidi_cache_size until after xrealloc returns, because it
16340 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16341 (bidi_cache_ensure_space): Also check that the bidi cache size
16342 does not exceed that of the largest Lisp string or buffer. See Eli
16343 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16345 * alloc.c (__malloc_size_t): Remove.
16346 All uses replaced by size_t. See Andreas Schwab's note
16347 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16349 * image.c: Improve checking for integer overflow.
16350 (check_image_size): Assume that f is nonnull, since
16351 it is always nonnull in practice. This is one less thing to
16352 worry about when checking for integer overflow later.
16353 (x_check_image_size): New function, which checks for integer
16354 overflow issues inside X.
16355 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16356 This removes the need for a memory_full check.
16357 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16358 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16359 (xbm_read_bitmap_data): Change locals back to 'int', since
16360 their values must fit in 'int'.
16361 (xpm_load_image, png_load, tiff_load):
16362 Invoke x_create_x_image_and_pixmap earlier,
16363 to avoid much needless work if the image is too large.
16364 (tiff_load): Treat overly large images as if
16365 x_create_x_image_and_pixmap failed, not as malloc failures.
16366 (gs_load): Use x_check_image_size.
16368 * gtkutil.c: Omit integer casts.
16369 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16370 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16372 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16374 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16375 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16376 would wrongly return t on a 64-bit host.
16378 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16379 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16380 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16381 and therefore cause GCC to emit a bogus diagnostic in some cases.
16383 * image.c: Integer signedness and overflow and related fixes.
16384 This is not an exhaustive set of fixes, but it's time to
16385 record what I've got.
16386 (lookup_pixel_color, check_image_size): Remove redundant decls.
16387 (check_image_size): Don't assume that arbitrary EMACS_INT values
16388 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16389 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16390 (tiff_load, imagemagick_load_image):
16391 Check for overflow in size calculations.
16392 (x_create_x_image_and_pixmap): Remove unnecessary test for
16393 xmalloc returning NULL; that can't happen.
16394 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16395 (xpm_color_bucket): Use better integer hashing function.
16396 (xpm_cache_color): Don't possibly over-allocate memory.
16397 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16398 (gif_memory_source):
16399 Use ptrdiff_t, not int or size_t, to record sizes.
16400 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16401 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16402 either works, as we prefer signed integers.
16403 (tiff_read_from_memory, tiff_write_from_memory):
16404 Return tsize_t, not size_t, since that's what the TIFF API wants.
16405 (tiff_read_from_memory): Don't fail simply because the read would
16406 go past EOF; instead, return a short read.
16407 (tiff_load): Omit no-longer-needed casts.
16408 (Fimagemagick_types): Don't assume size fits into 'int'.
16410 Improve hashing quality when configured --with-wide-int.
16411 * fns.c (hash_string): New function, taken from sxhash_string.
16412 Do not discard information about ASCII character case; this
16413 discarding is no longer needed.
16414 (sxhash-string): Use it. Change sig to match it. Caller changed.
16415 * lisp.h: Declare it.
16416 * lread.c (hash_string): Remove, since we now use fns.c's version.
16417 The fns.c version returns a wider integer if --with-wide-int is
16418 specified, so this should help the quality of the hashing a bit.
16420 * emacs.c: Integer overflow minor fix.
16421 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16422 Define only if GNU_LINUX.
16423 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16425 * dispnew.c: Integer signedness and overflow fixes.
16426 Remove unnecessary forward decls, that were a maintenance hassle.
16427 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16429 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16430 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16431 (prepare_desired_row, line_draw_cost):
16432 Use int, not unsigned, where either works.
16433 (save_current_matrix, restore_current_matrix):
16434 Use ptrdiff_t, not size_t, where either works.
16435 (init_display): Check for overflow more accurately, and without
16436 relying on undefined behavior.
16438 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16439 Remove, replacing with the new symbols in lisp.h. All uses changed.
16440 * fileio.c (make_temp_name):
16441 * filelock.c (lock_file_1, lock_file):
16442 * xdisp.c (message_dolog):
16443 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16444 Use pMd etc. instead.
16445 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16446 replacing the pWIDE etc. symbols removed from editfns.c.
16448 * keyboard.h (num_input_events): Now uintmax_t.
16449 This is (very slightly) less likely to mess up due to wraparound.
16452 * buffer.c: Integer signedness fixes.
16453 (alloc_buffer_text, enlarge_buffer_text):
16454 Use ptrdiff_t rather than size_t when either will do, as we prefer
16457 * alloc.c: Integer signedness and overflow fixes.
16458 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16459 (__malloc_size_t): Default to size_t, not to int.
16460 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16461 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16462 Prefer ptrdiff_t to size_t when either would do, as we prefer
16464 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16465 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16466 Now const. Initialize with values that are in range even if char
16468 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16469 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16470 These functions do the right thing with sizes > 2**32.
16471 (check_depth): Now ptrdiff_t, not int.
16472 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16473 Adjust to new way of storing sizes. Check for size overflow bugs
16475 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16476 slightly wrong anyway, as it missed one instance of
16477 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16478 (refill_memory_reserve): Omit needless cast to size_t.
16479 (mark_object_loop_halt): Mark as externally visible.
16481 * xselect.c: Integer signedness and overflow fixes.
16482 (Fx_register_dnd_atom, x_handle_dnd_message):
16483 Use ptrdiff_t, not size_t, since we prefer signed.
16484 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16485 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16486 x_dnd_atoms_size and x_dnd_atoms_length.
16488 * doprnt.c: Prefer signed to unsigned when either works.
16490 * doprnt.c (doprnt):
16492 * xdisp.c (vmessage):
16493 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16494 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16495 prefer signed arithmetic to avoid comparison confusion.
16496 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16497 but is a bit tricky.
16499 Assume freestanding C89 headers, string.h, stdlib.h.
16500 * data.c, doprnt.c, floatfns.c, print.c:
16501 Include float.h unconditionally.
16502 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16503 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16504 * regex.c: Likewise for stddef.h, string.h.
16505 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16506 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16507 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16508 (STDC_HEADERS): Remove obsolete defines.
16509 * sysdep.c: Include limits.h unconditionally.
16511 Assume support for memcmp, memcpy, memmove, memset.
16512 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16513 * regex.c (memcmp, memcpy):
16514 Remove; we assume C89 now.
16516 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16517 (__malloc_safe_bcopy): Remove; no longer needed.
16519 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16520 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16521 well either way, and we prefer signed to unsigned.
16523 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16525 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16526 closes the connection while we're reading (bug#9182).
16528 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16530 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16531 are specified (Bug#9168).
16533 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16535 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16536 Found by GCC static checking and --with-wide-int on a 32-bit host.
16538 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16540 * xdisp.c (compute_display_string_pos): Fix logic of caching
16541 previous display string position. Initialize cached_prev_pos to
16542 -1. Fixes slow-down at the beginning of a buffer.
16544 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16546 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16547 for attrs[LFACE_FONTSET_INDEX].
16549 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16551 * xml.c (parse_region): Remove unused local
16552 that was recently introduced.
16554 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16556 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16557 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16559 * xdisp.c (move_it_in_display_line_to): Record the best matching
16560 position for TO_CHARPOS while scanning the line, and restore it on
16561 exit if none of the characters scanned was an exact match.
16562 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16563 when exact match is impossible due to invisible text, and the
16564 lines are truncated.
16566 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16568 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16571 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16573 Fix a significant slow-down of cursor motion with C-n, C-p,
16574 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16575 auto-repeat under bidi redisplay in fontified buffers.
16576 * xdisp.c (compute_stop_pos_backwards): New function.
16577 (next_element_from_buffer): Call compute_stop_pos_backwards to
16578 find a suitable prev_stop when we find ourselves before
16580 (reseat): Don't look for prev_stop, as that could mean a very long
16582 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16583 <cached_disp_overlay_modiff>: Cache for last found display string
16585 (compute_display_string_pos): Return the cached position if asked
16586 about the same buffer in the same area of character positions, and
16587 the buffer wasn't changed since the time the display string
16588 position was cached.
16590 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16592 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16593 is an integer, which is important for empty lines. (Bug#9149)
16595 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16597 * frame.c (Fmodify_frame_parameters): In tty case, update the
16598 default face if necessary (Bug#4238).
16600 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16602 * editfns.c (Fstring_to_char): No need to explain what a character
16603 is in the docstring (Bug#6576).
16605 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16607 * xml.c (parse_region): Make sure we always return a tree.
16609 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16611 * xml.c (parse_region): If a document contains only comments,
16614 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16616 * xml.c (make_dom): Return comments, too.
16618 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16621 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16622 and the surrounding thread.
16623 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16624 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16625 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16627 * s/openbsd.h (BROKEN_SIGIO): Define.
16628 * unexelf.c (unexec) [__OpenBSD__]:
16629 Don't update the .mdebug section of the Alpha COFF symbol table.
16631 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16633 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16636 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16638 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16639 This fixes some race conditions on the permissions of any newly
16642 * alloc.c (valid_pointer_p): Use pipe, not open.
16643 This fixes some permissions issues when debugging.
16645 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16646 If fchown fails to set both uid and gid, try to set just gid,
16647 as that is sometimes allowed. Adjust the file's mode to eliminate
16648 setuid or setgid bits that are inappropriate if fchown fails.
16650 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16652 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16653 to compare Lisp_Objects.
16654 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16655 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16656 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16658 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16660 * lread.c (read_integer): Unread even EOF character.
16661 (read1): Likewise. Properly record start position of symbol.
16663 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16664 symbol character follows.
16666 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16668 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16669 This works around a problem with the previous change to Fcopy_file.
16670 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16671 and without this change, GCC might complain about discarding
16672 fchown's return value.
16674 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16676 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16678 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16680 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16682 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16684 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16685 it's used from the C level.
16687 * process.c: Use the same condition for POLL_FOR_INPUT in both
16688 keyboard.c and process.c (bug#1858).
16690 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16692 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16693 (Fgnutls_boot): Use it.
16695 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16697 * doc.c (Fsubstitute_command_keys): Revert last change.
16699 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16701 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16702 quotes the next character, and doesn't affect other longer
16703 sequences (bug#8935).
16705 * lread.c (syms_of_lread): Clarify that is isn't only
16706 `eval-buffer' and `eval-defun' that's affected by
16707 `lexical-binding' (bug#8460).
16709 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16711 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16712 bidi redisplay when a line includes both an image and is truncated.
16714 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16716 Fix minor problems found by static checking.
16717 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16718 (elsz): Now a signed constant, not a size_t var. We prefer signed
16719 types to unsigned, to avoid integer comparison confusion. Without
16720 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16721 "cannot optimize loop, the loop counter may overflow", a symptom
16723 * indent.c (Fvertical_motion): Mark locals as initialized.
16724 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16726 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16728 * search.c (Fre_search_backward): Mention `case-fold-search' in
16729 all the re_search_* functions (bug#8138).
16731 * keyboard.c (Fopen_dribble_file): Document when the file is

16744 bidi_it->string.schars.
16745 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16746 NULL (avoids a crash in bidi_paragraph_init).
16747 Initialize itb.string.lstring.
16748 (init_iterator): Call bidi_init_it only of a valid
16749 buffer position was specified. Initialize paragraph_embedding to
16751 (reseat_to_string): Initialize the bidi iterator.
16752 (display_string): If we need to ignore text properties of
16753 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16754 original value of -1 will not work with bidi.)
16755 (compute_display_string_pos): First arg is now struct
16756 `text_pos *'; all callers changed. Support display properties on
16758 (compute_display_string_end): Support display properties on Lisp
16760 (init_iterator, reseat_1, reseat_to_string): Initialize the
16761 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16762 when iterating on a string not from display properties).
16763 (compute_display_string_pos, compute_display_string_end):
16764 Fix calculation of the object to scan. Fixes an error when using
16766 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16767 base_level_stop; instead, set base_level_stop to BEGV.
16768 Fixes crashes in vertical-motion.
16769 (next_element_from_buffer): Improve commentary for when
16770 the iterator is before prev_stop.
16771 (init_iterator): Initialize bidi_p from the default value of
16772 bidi-display-reordering, not from buffer-local value. Use the
16773 buffer-local value only if initializing for buffer iteration.
16774 (handle_invisible_prop): Support invisible properties on strings
16775 that are being bidi-reordered.
16776 (set_iterator_to_next): Support bidi reordering of C strings and
16778 (next_element_from_string): Support bidi reordering of Lisp
16780 (handle_stop_backwards): Support Lisp strings as well.
16781 (display_string): Support display of R2L glyph rows.
16782 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16783 (init_iterator): Don't initialize it->bidi_p for strings
16785 (reseat_to_string): Initialize it->bidi_p for strings here.
16786 (next_element_from_string, next_element_from_c_string)
16787 (next_element_from_buffer): Add xassert's for correspondence
16788 between IT's object being iterated and it->bidi_it.string

16791 (next_element_from_c_string): Handle the case of the first string
16792 character that is not the first one in the visual order.
16793 (get_visually_first_element): New function, refactored from common
16794 parts of next_element_from_buffer, next_element_from_string, and
16795 next_element_from_c_string.
16796 (tool_bar_lines_needed, redisplay_tool_bar)
16797 (display_menu_bar): Force left-to-right direction. Add a FIXME
16798 comment for making that be controlled by a user option.
16799 (push_it, pop_it): Save and restore the state of the
16800 bidi iterator. Save and restore the bidi_p flag.
16801 (pop_it): Iterate out of display property for string iteration as
16803 (iterate_out_of_display_property): Support iteration over strings.
16804 (handle_single_display_spec): Set up it->bidi_it for iteration
16805 over a display string, and call bidi_init_it.
16806 (handle_single_display_spec, next_overlay_string)
16807 (get_overlay_strings_1, push_display_prop): Set up the bidi
16808 iterator for displaying display or overlay strings.
16809 (forward_to_next_line_start): Don't use the shortcut if
16811 (back_to_previous_visible_line_start): If handle_display_prop
16812 pushed the iterator stack, restore the internal state of the bidi
16813 iterator by calling bidi_pop_it same number of times.
16814 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16815 and we are bidi-iterating, don't decrement the iterator position;
16816 instead, set the first_elt flag in the bidi iterator, to produce
16818 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16819 (push_display_prop): xassert that we are iterating a buffer.
16820 (push_it, pop_it): Save and restore paragraph_embedding member.
16821 (handle_single_display_spec, next_overlay_string)
16822 (get_overlay_strings_1, reseat_1, reseat_to_string)
16823 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16824 correctly. Don't assume unibyte strings are not bidi-reordered.
16825 (compute_display_string_pos)
16826 (compute_display_string_end): Fix handling the case of C string.
16827 (push_it, pop_it): Save and restore from_disp_prop_p.

16832 popping after iteration over a string that came from a display
16833 property. Fix a typo in popping stretch info. Add an assertion
16834 for verifying that the iterator position is in sync with the bidi
16836 (handle_single_display_spec, get_overlay_strings_1)
16837 (push_display_prop): Fix initialization of paragraph direction for
16838 string when that of the parent object is not yet determined.
16839 (reseat_1): Call bidi_init_it to resync the bidi
16840 iterator with IT's position. (Bug#7616)
16841 (find_row_edges): If ROW->start.pos gives position
16842 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
16843 (handle_stop, back_to_previous_visible_line_start, reseat_1):
16844 Reset the from_disp_prop_p flag.
16845 (SAVE_IT, RESTORE_IT): New macros.
16846 (pos_visible_p, face_before_or_after_it_pos)
16847 (back_to_previous_visible_line_start)
16848 (move_it_in_display_line_to, move_it_in_display_line)
16849 (move_it_to, move_it_vertically_backward, move_it_by_lines)
16850 (try_scrolling, redisplay_window, display_line): Use them when
16851 saving a temporary copy of the iterator and restoring it back.
16852 (back_to_previous_visible_line_start, reseat_1)
16853 (init_iterator): Empty the bidi cache "stack".
16854 (move_it_in_display_line_to): If iterator ended up at
16855 EOL, but we never saw any buffer positions smaller than
16856 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16857 motion in bidi-reordered lines.
16858 (move_it_in_display_line_to): Record prev_method and prev_pos
16859 immediately before the call to set_iterator_to_next. Fixes cursor
16860 motion in bidi-reordered lines with stretch glyphs and strings
16861 displayed in margins. (Bug#8133) (Bug#8867)
16862 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16864 (pos_visible_p): Support positions in bidi-reordered lines.
16865 Save and restore bidi cache.
16867 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16868 (bidi_paragraph_info): Delete unused struct.
16869 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16870 (bidi_cache_start): New variable.
16871 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
16873 (bidi_cache_fetch_state, bidi_cache_search)
16874 (bidi_cache_find_level_change, bidi_cache_iterator_state)

16879 (bidi_fetch_char): Accept new argument STRING; all callers
16880 changed. Support iteration over a string. Support strings with
16881 display properties. Support unibyte strings. Fix the type of
16882 `len' according to what STRING_CHAR_AND_LENGTH expects.
16883 (bidi_paragraph_init, bidi_resolve_explicit_1)
16884 (bidi_resolve_explicit, bidi_resolve_weak)
16885 (bidi_level_of_next_char, bidi_move_to_visually_next):
16886 Support iteration over a string.
16887 (bidi_set_sor_type, bidi_resolve_explicit_1)
16888 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16889 can now be zero (for strings); special values 0 and -1 were
16890 changed to -1 and -2, respectively.
16891 (bidi_char_at_pos): New function.
16892 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
16893 Call it instead of FETCH_MULTIBYTE_CHAR.

16903 (bidi_initialize): Initialize the bidi cache start stack pointer.
16904 (bidi_cache_ensure_space): New function, refactored from part of

16908 (bidi_count_bytes, bidi_char_at_pos): New functions.
16909 (bidi_cache_search): Don't assume bidi_cache_last_idx is

16978 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16980 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16981 The old code sometimes used this field without initializing it.
16983 * alloc.c (gc_sweep): Don't read past end of array.
16984 In theory, the old code could also have corrupted Emacs internals,
16985 though it'd be very unlikely.

17248 (clone_per_buffer_values): Don't assume that

17250 This isn't true in general, and it's particularly not true
17251 if Emacs is configured with --with-wide-int.
17252 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17289 Random fixes. E.g., (random) never returned negative values.
17290 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17291 subseconds part to the entropy, as that's a bit more random.
17292 Prefer signed to unsigned, since the signedness doesn't matter and
17293 in general we prefer signed. When given a limit, use a
17294 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17295 latter isn't right if USE_2_TAGS_FOR_INTS.
17296 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17297 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17307 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17309 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17310 This is more efficient than Ffile_directory_p and avoids a minor race.
17312 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17314 * buffer.c (Foverlay_put): Say what the return value is
17317 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17318 is a directory before asking whether to use the file name
17320 (barf_or_query_if_file_exists): Make the "File is a directory"
17321 error be more correct.
17323 * fns.c (Frequire): Remove the mention of the .gz files, since
17324 that's installation-specific, but keep the mention of
17325 `get-load-suffixes'.

17329 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17337 Qgnutls_bootprop_verify_error (which is no longer used).
17339 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17340 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17341 Also (re)move comments that are misplaced or no longer relevant.
17343 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17345 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17442 * eval.c (struct backtrace): Simplify and port the data structure.
17443 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17444 signed bit field, as this assumption is not portable and it makes
17445 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17446 "char debug_on_exit : 1" as this is not portable either; instead,
17447 use the portable "unsigned int debug_on_exit : 1". Remove unused
17448 member evalargs. Remove obsolete comments about cc bombing out.
17450 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17522 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17523 and use min_width/height from frames size_hint to set
17524 min_width/height (Bug#8919).

17638 (read1): Check for integer overflow in radices, and in
17639 read-circle numbers.

17683 on undefined behavior with wrong number of arguments.
17684 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17685 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17686 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17687 since we're not interested in debugging glyphs with old libraries.
17688 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17689 GCC 4.6.0's static checking.

17730 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17731 (x_session_initialize): Do not assume string length fits in int.
17733 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

17759 * minibuf.c (Fread_buffer):
17760 * lread.c (intern, intern_c_string):
17761 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

17779 Don't assume pid_t and time_t fit in unsigned long.
17780 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17781 (current_lock_owner): Prefer signed type for sizes.
17782 Use memcpy, not strncpy, where memcpy is what is really wanted.
17783 Don't assume (via atoi) that time_t and pid_t fit in int.
17784 Check for time_t and/or pid_t out of range, e.g., via a network share.
17785 Don't alloca where an auto var works fine.

17798 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17800 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17801 We prefer signed integers, even for size calculations.
17803 * emacs.c: Don't assume string length fits in 'int'.
17804 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17805 (main): Don't invoke strlen when not needed.
17807 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17808 (XD_DEBUG_MESSAGE): Don't waste a byte.
17810 * callproc.c (getenv_internal_1, getenv_internal)
17811 (Fgetenv_internal):
17812 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17814 * lread.c (invalid_syntax): Omit length argument.
17815 All uses changed. This doesn't fix a bug, but it simplifies the
17816 code away from its former Hollerith-constant appearance, and it's
17817 one less 'int' to worry about when looking at integer-overflow issues.
17818 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17820 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17821 This didn't break anything, but it didn't help either.
17822 It's confusing to put a bogus integer in a place where the actual
17823 value does not matter.
17824 (LIST_END_P): Remove unused macro and its bogus comment.
17825 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17827 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17828 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17830 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17831 We prefer signed types, and the value cannot exceed the EMACS_INT
17832 range anyway (because otherwise the length would not be representable).
17833 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17834 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17835 This avoids a GCC warning when WIDE_EMACS_INT.
17837 * indent.c (sane_tab_width): New function.
17838 (current_column, scan_for_column, Findent_to, position_indentation)
17839 (compute_motion): Use it. This is just for clarity.
17840 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17842 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17844 * lisp.h (lint_assume): New macro.
17845 * composite.c (composition_gstring_put_cache):
17846 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17848 * editfns.c, insdel.c:
17849 Omit unnecessary forward decls, to simplify future changes.
17851 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17853 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17855 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17856 Use much-faster test for byte-length change.
17857 Don't assume string byte-length fits in 'int'.
17858 Check that character arg fits in 'int'.
17859 (mapcar1): Declare byte as byte, for clarity.
17861 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17863 * fns.c (concat): Catch string overflow earlier.
17864 Do not rely on integer wraparound.
17866 * dispextern.h (struct it.overlay_strings_charpos)
17867 (struct it.selective): Now EMACS_INT, not int.
17868 * xdisp.c (forward_to_next_line_start)
17869 (back_to_previous_visible_line_start)
17870 (reseat_at_next_visible_line_start, next_element_from_buffer):
17871 Don't arbitrarily truncate the value of 'selective' to int.
17873 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17875 * composite.c: Don't truncate sizes to 'int'.
17876 (composition_gstring_p, composition_reseat_it)
17877 (composition_adjust_point): Use EMACS_INT, not int.
17878 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17879 not EMACS_UINT, for indexes.
17881 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17883 * buffer.c: Include <verify.h>.
17884 (struct sortvec.priority, struct sortstr.priority):
17885 Now EMACS_INT, not int.
17886 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17887 (struct sortstr.size, record_overlay_string)
17888 (struct sortstrlist.size, struct sortlist.used):
17889 Don't truncate size to int.
17890 (record_overlay_string): Check for size-calculation overflow.
17891 (init_buffer_once): Check at compile-time, not run-time.
17893 2011-06-22 Jim Meyering <meyering@redhat.com>
17895 Don't leak an XBM-image-sized buffer
17896 * image.c (xbm_load): Free the image buffer after using it.
17898 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17901 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17902 that Sun C diagnosed.
17903 * fns.c (secure_hash): Fix pointer signedness issue.
17904 * intervals.c (static_offset_intervals): New function.
17905 (offset_intervals): Use it.
17907 2011-06-21 Leo Liu <sdl.web@gmail.com>
17910 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17913 * fns.c (secure_hash): Rename from crypto_hash_function and change
17914 the first arg to accept symbols.
17915 (Fsecure_hash): New primitive.
17916 (syms_of_fns): New symbols.
17918 2011-06-20 Deniz Dogan <deniz@dogan.se>
17920 * process.c (Fset_process_buffer): Clarify return value in
17923 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17925 * dispnew.c (add_window_display_history): Use BVAR.
17927 * xdisp.c (debug_method_add): Use BVAR.
17928 (check_window_end, dump_glyph_matrix, dump_glyph)
17929 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17931 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17934 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17935 check till after the cache is created in init_frame_faces.
17937 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17939 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17941 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17943 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17944 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17945 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17947 Improve buffer-overflow checking (Bug#8873).
17948 * fileio.c (Finsert_file_contents):
17949 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17950 Remove the old (too-loose) buffer overflow checks.
17951 They weren't needed, since make_gap checks for buffer overflow.
17952 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17953 The old code merely checked for Emacs fixnum overflow, and relied
17954 on undefined (wraparound) behavior. The new code avoids undefined
17955 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17957 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17958 Tune. Don't use wider integers than needed. Don't use alloca.
17959 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17961 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17963 * insdel.c, lisp.h (buffer_overflow): New function.
17964 (insert_from_buffer_1, replace_range, replace_range_2):
17965 * insdel.c (make_gap_larger):
17966 * editfns.c (Finsert_char):
17967 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17969 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17971 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17973 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17975 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17976 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17978 * fileio.c: Don't assume EMACS_INT fits in off_t.
17979 (emacs_lseek): New static function.
17980 (Finsert_file_contents, Fwrite_region): Use it.
17981 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17983 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17985 * fns.c: Don't overflow int when computing a list length.
17986 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17987 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17988 truncation on 64-bit hosts. Check for QUIT every
17989 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17990 faster and is responsive enough.
17991 (Flength): Report an error instead of overflowing an integer.
17992 (Fsafe_length): Return a float if the value is not representable
17993 as a fixnum. This shouldn't happen except in contrived situations.
17994 (Fnthcdr, Fsort): Don't assume list length fits in int.
17995 (Fcopy_sequence): Don't assume vector length fits in int.
17997 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17998 (header_size, word_size): New constants.
17999 (allocate_vectorlike): Don't check size overflow here.
18000 (allocate_vector): Check it here instead, since this is the only
18001 caller of allocate_vectorlike that could cause overflow.
18002 Check that the new vector's length is representable as a fixnum.
18004 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18005 The previous code was bogus. For example, next_almost_prime (32)
18006 returned 39, which is undesirable as it is a multiple of 3; and
18007 next_almost_prime (24) returned 25, which is a multiple of 5 so
18008 why was the code bothering to check for multiples of 7?
18010 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18012 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18014 Variadic C functions now count arguments with ptrdiff_t.
18015 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18016 Back then I didn't know that the Emacs coding style prefers signed int.
18017 Also, in the meantime I found a few more instances where arguments
18018 were being counted with int, which may truncate counts on 64-bit
18019 machines, or EMACS_INT, which may be unnecessarily wide.
18020 * lisp.h (struct Lisp_Subr.function.aMANY)
18021 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18022 Arg counts are now ptrdiff_t, not size_t.
18023 All variadic functions and their callers changed accordingly.
18024 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18025 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18026 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18027 * callint.c (Fcall_interactively): Check arg count for overflow,
18028 to avoid potential buffer overrun. Use signed char, not 'int',
18029 for 'varies' array, so that we needn't bother to check its size
18030 calculation for overflow.
18031 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18032 * eval.c (apply_lambda):
18033 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18034 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18035 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18037 * callint.c (Fcall_interactively): Don't use index var as event count.
18039 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18040 * mem-limits.h (SIZE): Remove; no longer used.
18042 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18044 Remove unnecessary casts.
18045 * xterm.c (x_term_init):
18046 * xfns.c (x_set_border_pixel):
18047 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18048 These aren't needed now that we assume ANSI C.
18050 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18051 It's more likely to cause problems (due to unsigned overflow)
18054 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18056 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18058 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18060 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18062 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18064 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18066 GLYPH_CODE_FACE returns EMACS_INT, not int.
18067 * dispextern.h (merge_faces):
18068 * xfaces.c (merge_faces):
18069 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18070 Don't assume EMACS_INT fits in int.
18072 * character.h (CHAR_VALID_P): Remove unused parameter.
18073 * fontset.c, lisp.h, xdisp.c: All uses changed.
18075 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18077 * fns.c (concat): Minor tuning based on overflow analysis.
18078 This doesn't fix any bugs. Use int to hold character, instead
18079 of constantly refetching from Emacs object. Use XFASTINT, not
18080 XINT, for value known to be a character. Don't bother comparing
18081 a single byte to 0400, as it's always less.
18083 * floatfns.c (Fexpt):
18084 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18086 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18089 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18091 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18092 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18093 incorrectly succeed when S was a string, because 4294967386 was
18094 truncated before it was used.
18096 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18097 Otherwise, an out-of-range integer could cause undefined behavior
18100 * composite.c: Use int, not EMACS_INT, for characters.
18101 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18102 EMACS_INT, for values that are known to be in character range.
18103 This doesn't fix any bugs but is the usual style inside Emacs and
18104 may generate better code on 32-bit machines.
18106 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18107 This is for reasons similar to the recent CHAR_STRING fix.
18108 * charset.c (Fencode_char): Check that character arg is actually
18109 a character. Pass an int to ENCODE_CHAR.
18110 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18111 wider than 'int', as a compile-time check to prevent future regressions
18114 * character.c (char_string): Remove unnecessary casts.
18116 Make sure a 64-bit char is never passed to CHAR_STRING.
18117 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18118 by silently ignoring the top 32 bits, allowing some values
18119 that were far too large to be valid characters.
18120 * character.h: Include <verify.h>.
18121 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18122 arguments are no wider than unsigned, as a compile-time check
18123 to prevent future regressions in this area.
18125 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18126 (Fsubst_char_in_region):
18128 * xdisp.c (decode_mode_spec_coding):
18129 Adjust to CHAR_STRING's new requirement.
18130 * editfns.c (Finsert_char, Fsubst_char_in_region):
18131 * fns.c (concat): Check that character args are actually
18132 characters. Without this test, these functions did the wrong
18133 thing with wildly out-of-range values on 64-bit hosts.
18135 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18136 These casts should not be needed on 32-bit hosts, either.
18137 * keyboard.c (read_char):
18138 * lread.c (Fload): Remove casts to unsigned.
18140 * lisp.h (UNSIGNED_CMP): New macro.
18141 This fixes comparison bugs on 64-bit hosts.
18142 (ASCII_CHAR_P): Use it.
18143 * casefiddle.c (casify_object):
18144 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18145 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18146 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18147 * dispextern.h (FACE_FROM_ID):
18148 * keyboard.c (read_char): Use UNSIGNED_CMP.
18150 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18151 not to EMACS_INT, to avoid GCC warning.
18153 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18155 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18156 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18157 isn't needed on 32-bit machines.
18159 * buffer.c (Fgenerate_new_buffer_name):
18160 Use EMACS_INT for count, not int.
18161 (advance_to_char_boundary): Return EMACS_INT, not int.
18163 * data.c (Qcompiled_function): Now static.
18165 * window.c (window_body_lines): Now static.
18167 * image.c (gif_load): Rename local to avoid shadowing.
18169 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18170 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18171 * alloc.c (make_save_value): Integer argument is now of type
18172 ptrdiff_t, not int.
18173 (mark_object): Use ptrdiff_t, not int.
18174 * lisp.h (pD): New macro.
18175 * print.c (print_object): Use it.
18177 * alloc.c: Use EMACS_INT, not int, to count objects.
18178 (total_conses, total_markers, total_symbols, total_vector_size)
18179 (total_free_conses, total_free_markers, total_free_symbols)
18180 (total_free_floats, total_floats, total_free_intervals)
18181 (total_intervals, total_strings, total_free_strings):
18182 Now EMACS_INT, not int. All uses changed.
18183 (Fgarbage_collect): Compute overall total using a double, so that
18184 integer overflow is less likely to be a problem. Check for overflow
18185 when converting back to an integer.
18186 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18187 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18188 These were 'int' variables that could overflow on 64-bit hosts;
18189 they were never used, so remove them instead of repairing them.
18190 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18191 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18192 Previously, this ceilinged at INT_MAX, but that doesn't work on
18194 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18196 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18197 (allocate_vectorlike): Check for ptrdiff_t overflow.
18198 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18199 when a (possibly-narrower) signed value would do just as well.
18200 We prefer using signed arithmetic, to avoid comparison confusion.
18202 * alloc.c: Catch some string size overflows that we were missing.
18203 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18204 for convenience in STRING_BYTES_MAX.
18205 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18206 The definition here is exact; the one in lisp.h was approximate.
18207 (allocate_string_data): Check for string overflow. This catches
18208 some instances we weren't catching before. Also, it catches
18209 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18210 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18211 and ptrdiff_t and EMACS_INT are both 64 bits.
18213 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18214 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18215 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18217 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18219 * alloc.c (Fmake_string): Check for out-of-range init.
18221 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18223 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18225 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18227 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18228 xg_get_default_scrollbar_width.
18230 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18231 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18232 (style_changed_cb): Call update_theme_scrollbar_width and call
18233 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18234 all frames (Bug#8505).
18235 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18236 Call gtk_window_set_resizable if HAVE_GTK3.

18685 Fframe_first_window and Fset_frame_selected_window to window.h.
18687 * window.h: Move EXFUNS for Fframe_root_window,
18688 Fframe_first_window and Fset_frame_selected_window here from

18711 (Fwindow_minibuffer_p): Move up in code and simplify.
18712 (Fset_frame_selected_window): Move here from frame.c.
18714 (Fselected_window, select_window, Fselect_window): Move up in
18715 code. Minor doc-string fixes.
18717 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
18719 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18720 Do not assume that spare memory exists; that assumption is valid
18721 only if SYSTEM_MALLOC.
18722 (LARGE_REQUEST): New macro, so that the issue of large requests
18723 is separated from the issue of spare memory.
18725 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
18727 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

18753 New error handlers.
18754 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18755 Obey Vx_select_enable_clipboard_manager. Catch errors in
18756 x_clipboard_manager_save (Bug#8779).
18757 (Vx_select_enable_clipboard_manager): New variable.
18758 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18760 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18762 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18764 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18766 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18767 in the current matrix if keep_current_p is non-zero.

18773 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18775 Support bidi reordering of text covered by display properties.
18777 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18778 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18779 (bidi_cache_search, bidi_cache_iterator_state)
18780 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18781 (bidi_level_of_next_char, bidi_move_to_visually_next):
18782 Support character positions inside a run of characters covered by a
18784 (bidi_paragraph_init, bidi_resolve_explicit_1)
18785 (bidi_level_of_next_char): Call bidi_fetch_char and
18786 bidi_fetch_char_advance instead of FETCH_CHAR and
18787 FETCH_CHAR_ADVANCE.
18788 (bidi_init_it): Initialize new members.
18789 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18791 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18792 instead of using explicit *_CHAR codes.
18793 (bidi_resolve_explicit, bidi_resolve_weak):
18794 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18795 bidirectional text is supported only in multibyte buffers.
18796 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18797 it to initialize the frame_window_p member of struct bidi_it.
18798 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18799 (bidi_resolve_explicit, bidi_resolve_weak)

18801 bidi_it->nchars is non-positive.
18802 (bidi_level_of_next_char): Don't try to lookup the cache for the
18803 next/previous character if nothing is cached there yet, or if we
18804 were just reseat()'ed to a new position.
18806 * xdisp.c (set_cursor_from_row): Set start and stop points
18807 according to the row's direction when priming the loop that looks
18808 for the glyph on which to display cursor.
18809 (single_display_spec_intangible_p): Function deleted.
18810 (display_prop_intangible_p): Reimplement to call
18811 handle_display_spec instead of single_display_spec_intangible_p.
18812 Accept 3 additional arguments needed by handle_display_spec.
18813 This fixes incorrect cursor motion across display property with complex
18814 values: lists, `(when COND...)' forms, etc.
18815 (single_display_spec_string_p): Support property values that are
18816 lists with the argument STRING its top-level element.
18817 (display_prop_string_p): Fix the condition for processing a
18818 property that is a list to be consistent with handle_display_spec.
18819 (handle_display_spec): New function, refactored from the
18820 last portion of handle_display_prop.
18821 (compute_display_string_pos): Accept additional argument
18822 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18823 value of a `display' property is a "replacing spec".
18824 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18825 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18826 the display property, but just return a value indicating whether
18827 the display property will replace the characters it covers.
18828 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18829 frame_window_p members of struct bidi_it.
18830 (compute_display_string_pos, compute_display_string_end):
18832 (push_it): Accept second argument POSITION, where pop_it should
18833 jump to continue iteration.
18834 (reseat_1): Initialize bidi_it.disp_pos.
18836 * keyboard.c (adjust_point_for_property): Adjust the call to
18837 display_prop_intangible_p to its new signature.
18839 * dispextern.h (struct bidi_it): New member frame_window_p.
18840 (bidi_init_it): Update prototypes.
18841 (display_prop_intangible_p): Update prototype.
18842 (compute_display_string_pos, compute_display_string_end):
18843 Declare prototypes.
18844 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18847 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18849 Malloc failure behavior now depends on size of allocation.
18850 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18851 * lisp.h: Change signatures accordingly.
18852 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18853 All callers changed. (Bug#8762)
18855 * gnutls.c: Use Emacs's memory allocators.
18856 Without this change, the gnutls library would invoke malloc etc.
18857 directly, which causes problems on non-SYNC_INPUT hosts, and which
18858 runs afoul of improving memory_full behavior. (Bug#8761)
18859 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18860 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18861 xfree instead of the default malloc, realloc, free.
18862 (Fgnutls_boot): No need to check for memory allocation failure,
18863 since xmalloc does that for us.
18865 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18866 * category.c (hash_get_category_set):
18867 * ccl.c (ccl_driver):
18868 * charset.c (Fdefine_charset_internal):

18879 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18880 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18881 * image.c (make_image, search_image_cache, lookup_image)
18882 (xpm_put_color_table_h):
18883 * lisp.h (struct Lisp_Hash_Table):
18884 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18885 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18886 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18887 * alloc.c (allocate_vectorlike):
18888 Check for overflow in vector size calculations.
18889 * ccl.c (ccl_driver):
18890 Check for overflow when converting EMACS_INT to int.
18891 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18892 need to be updated by these changes.
18893 * fns.c (make_hash_table, maybe_resize_hash_table):
18894 Check for integer overflow with large hash tables.
18895 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18896 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18897 (SXHASH_REDUCE): New macro.
18898 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18899 Use it instead of discarding useful hash info with large hash values.
18900 (sxhash_float): New function.
18901 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18902 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18903 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18904 Rewrite to use FIXNUM_BITS, as this simplifies things.
18905 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18906 Adjust signatures to match updated version of code.
18907 (consing_since_gc): Now EMACS_INT, since a single hash table can
18908 use more than INT_MAX bytes.
18910 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18912 Make it possible to build with GCC-4.6+ -O2 -flto.
18914 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18916 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18918 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18919 Call minibuffer-inactive-mode.
18921 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18923 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18924 Update dependencies.
18926 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18928 * data.c (init_data): Remove code for UTS, this system is not
18931 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18933 Don't force ./temacs to start in terminal mode.
18935 * frame.c (make_initial_frame): Initialize faces in all cases, not
18936 only when CANNOT_DUMP is defined.
18937 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18939 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18941 * dispnew.c (add_window_display_history): Use const for the string
18942 pointer. Remove declaration, not needed.
18944 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18946 Use 'inline', not 'INLINE'.
18947 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18948 * alloc.c, fontset.c (INLINE): Remove.
18949 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18950 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18951 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18952 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18953 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18955 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18957 Make it possible to run ./temacs.
18959 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18960 syms_of_callproc does the same thing. Remove test for
18961 "initialized", do it in the caller.
18962 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18964 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18966 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18967 (read_minibuf): Use get_minibuffer.
18968 (syms_of_minibuf): Use DEFSYM.
18969 (Qmetadata): New var.
18970 * data.c (Qbuffer): Don't make it static.
18971 (syms_of_data): Use DEFSYM.
18973 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18975 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18976 (CCL_CODE_MIN): New macro.
18978 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18980 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18982 * eval.c (Qdebug): Now static.
18983 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18984 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18985 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18987 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18989 * image.c: Various fixes to ImageMagick code comments.
18990 (Fimagemagick_types): Doc fix.
18992 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18994 Minor fixes prompted by GCC 4.6.0 warnings.
18996 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18998 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18999 (x_clipboard_manager_save_all): Move extern decl to ...
19000 * xterm.h: ... here, so that it can be checked for consistency.
19002 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19004 * xselect.c (x_clipboard_manager_save_frame)
19005 (x_clipboard_manager_save_all): New functions.
19006 (Fx_clipboard_manager_save): Lisp function deleted.
19008 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19009 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19011 * xterm.h: Update prototype.
19013 2011-05-28 William Xu <william.xwl@gmail.com>
19015 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19016 exiting (Bug#8239).
19018 2011-05-28 Jim Meyering <meyering@redhat.com>
19020 Avoid a sign-extension bug in crypto_hash_function.
19021 * fns.c (to_uchar): Define.
19022 (crypto_hash_function): Use it to convert some newly-signed
19023 variables to unsigned, to avoid sign-extension bugs. For example,
19024 without this change, (md5 "truc") would evaluate to
19025 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19026 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19027 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19029 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19031 Integer overflow fixes.
19033 * dbusbind.c: Serial number integer overflow fixes.
19034 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19035 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19036 to hold a serial number that is too large for a fixnum.
19037 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19038 Check for serial numbers out of range. Decode any serial number
19039 that was so large that it became a float. (Bug#8722)
19041 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19042 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19043 Use XFASTINT rather than XUINT when numbers are nonnegative.
19044 (xd_append_arg, Fdbus_method_return_internal):
19045 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19046 arguments, check that Lisp number is nonnegative, rather than
19047 silently wrapping negative numbers around. (Bug#8722)
19048 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19051 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19053 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19055 ccl: Add integer overflow checks.
19056 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19057 (IN_INT_RANGE): New macros.
19058 (ccl_driver): Use them to check for integer overflow when
19059 decoding a CCL program. Many of the new checks are whether XINT (x)
19060 fits in int; it doesn't always, on 64-bit hosts. The new version
19061 doesn't catch all possible integer overflows, but it's an
19062 improvement. (Bug#8719)
19064 * alloc.c (make_event_array): Use XINT, not XUINT.
19065 There's no need for unsigned here.
19067 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19068 This follows up to the 2011-05-06 change that substituted uintptr_t
19069 for EMACS_INT. This case wasn't caught back then.
19071 Rework Fformat to avoid integer overflow issues.
19072 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19073 now (part of C89). Include <verify.h>.
19074 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19075 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19076 (Fformat): Avoid the prepass trying to compute sizes; it was only
19077 approximate and thus did not catch overflow reliably. Instead, walk
19078 through the format just once, formatting and computing sizes as we go,
19079 checking for integer overflow at every step, and allocating a larger
19080 buffer as needed. Keep track separately whether the format is
19081 multibyte. Keep only the most-recently calculated precision, rather
19082 than them all. Record whether each argument has been converted to
19083 string. Use EMACS_INT, not int, for byte and char and arg counts.
19084 Support field widths and precisions larger than INT_MAX. Avoid
19085 sprintf's undefined behavior with conversion specifications such as %#d
19086 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19087 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19088 formatting out-of-range floating point numbers with int
19089 formats. (Bug#8668)
19091 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19093 * data.c: Avoid integer truncation in expressions involving floats.
19094 * data.c: Include <intprops.h>.
19095 (arith_driver): When there's an integer overflow in an expression
19096 involving floating point, convert the integers to floating point
19097 so that the resulting value does not suffer from catastrophic
19098 integer truncation. For example, on a 64-bit host (* 4
19099 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19100 Do not rely on undefined behavior after integer overflow.
19102 merge count_size_as_multibyte, parse_str_to_multibyte
19103 * character.c, character.h (count_size_as_multibyte):
19104 Rename from parse_str_to_multibyte; all uses changed.
19105 Check for integer overflow.
19106 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19107 since it's now a duplicate of the other. This is more of
19108 a character than a buffer op, so better that it's in character.c.
19109 * fns.c, print.c: Adjust to above changes.
19111 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19113 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19115 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19117 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19118 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19119 (x_clipboard_manager_save): Now static.
19120 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19122 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19123 (crypto_hash_function): Now static.
19124 Fix pointer signedness problems. Avoid unnecessary initializations.
19126 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19128 * termhooks.h (Vselection_alist): Make it terminal-local.
19130 * terminal.c (create_terminal): Initialize it.
19132 * xselect.c: Support for clipboard managers.
19133 (Vselection_alist): Move to termhooks.h as terminal-local var.
19134 (LOCAL_SELECTION): New macro.
19135 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19136 (symbol_to_x_atom): Remove gratuitous arg.
19137 (x_handle_selection_request, lisp_data_to_selection_data)
19138 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19139 (x_own_selection, x_get_local_selection, x_convert_selection):
19140 New arg, specifying work frame. Use terminal-local Vselection_alist.
19141 (some_frame_on_display): Delete unused function.
19142 (Fx_own_selection_internal, Fx_get_selection_internal)
19143 (Fx_disown_selection_internal, Fx_selection_owner_p)
19144 (Fx_selection_exists_p): New optional frame arg.
19145 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19146 (x_handle_selection_clear): Don't treat other terminals with the
19147 same keyboard specially. Use the terminal-local Vselection_alist.
19148 (x_clear_frame_selections): Use Frun_hook_with_args.
19150 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19152 * xterm.h: Add support for those atoms.
19154 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19156 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19157 (converted_selections, conversion_fail_tag): New global variables.
19158 (x_selection_request_lisp_error): Free the above.
19159 (x_get_local_selection): Remove unnecessary code.
19160 (x_reply_selection_request): Args changed; handle arbitrary array
19161 of converted selections stored in converted_selections.
19162 Separate the XChangeProperty and SelectionNotify steps.
19163 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19164 (x_convert_selection): New function.
19165 (x_handle_selection_event): Simplify.
19166 (x_get_foreign_selection): Don't ignore incoming requests while
19167 waiting for an answer; this will fail when we implement
19168 SAVE_TARGETS, and seems unnecessary anyway.
19169 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19170 (Vx_sent_selection_functions): Doc fix.
19172 2011-05-26 Leo Liu <sdl.web@gmail.com>
19174 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19176 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19178 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19180 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19181 for fringe update if it has periodic bitmap.
19182 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19183 and fringe_bitmap_periodic_p.
19185 * fringe.c (get_fringe_bitmap_data): New function.
19186 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19187 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19188 row. Mark glyph row for fringe update if periodicity changed.
19190 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19191 for fringe update unless it has periodic bitmap.
19193 2011-05-25 Kenichi Handa <handa@m17n.org>
19195 * xdisp.c (get_next_display_element): Set correct it->face_id for
19196 a static composition.
19198 2011-05-24 Leo Liu <sdl.web@gmail.com>
19201 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19203 * fns.c (crypto_hash_function, Fsha1): New function.
19204 (Fmd5): Use crypto_hash_function.
19205 (syms_of_fns): Add Ssha1.
19207 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19209 * gnutls.c: Remove unused macros.
19210 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19211 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19212 Remove macros that are defined and never used.
19213 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19215 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19217 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19218 (Fx_get_selection_internal): Minor cleanup.
19219 (Fx_own_selection_internal): Rename arguments for consistency with
19222 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19224 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19226 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19228 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19230 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19232 * dispnew.c (scrolling_window): Don't exclude the case that the
19233 last enabled row in the desired matrix touches the bottom boundary.
19235 2011-05-21 Glenn Morris <rgm@gnu.org>
19237 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19238 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19239 and add some more files.
19241 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19243 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19244 report_file_error introduced by the change from 2011-05-07.
19246 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19248 * systime.h (Time): Define only if emacs is defined.
19249 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19250 where the include path doesn't have X11/X.h by default. See
19251 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19253 2011-05-20 Kenichi Handa <handa@m17n.org>
19255 * composite.c (find_automatic_composition): Fix previous change.
19257 2011-05-20 Glenn Morris <rgm@gnu.org>
19259 * lisp.mk: New file, split from Makefile.in.
19260 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19261 (shortlisp): Remove.
19262 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19264 2011-05-19 Glenn Morris <rgm@gnu.org>
19266 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19267 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19268 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19269 (lisp): Set the order to that of loadup.el.
19270 (shortlisp): Make it a copy of $lisp.
19271 (SOME_MACHINE_LISP): Remove.
19272 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19273 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19275 2011-05-18 Kenichi Handa <handa@m17n.org>
19277 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19278 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19279 (find_automatic_composition): Mostly rewrite for efficiency.
19281 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19283 * makefile.w32-in: Update dependencies.
19285 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19287 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19288 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19290 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19292 Fix some integer overflow issues, such as string length overflow.
19294 * insdel.c (count_size_as_multibyte): Check for string overflow.
19296 * character.c (lisp_string_width): Check for string overflow.
19297 Use EMACS_INT, not int, for string indexes and lengths; in
19298 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19299 the resulting string length overflows an EMACS_INT; instead,
19300 report a string overflow if no precision given. When checking for
19301 precision exhaustion, use a check that cannot possibly have
19302 integer overflow. (Bug#8675)
19303 * character.h (lisp_string_width): Adjust to new signature.
19305 * alloc.c (string_overflow): New function.
19306 (Fmake_string): Use it. This doesn't change behavior, but saves
19307 a few bytes and will simplify future changes.
19308 * character.c (string_escape_byte8): Likewise.
19309 * lisp.h (string_overflow): New decl.
19311 Fixups, following up to the user-interface timestamp change.
19312 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19313 for UI timestamps, instead of unsigned long.
19314 * msdos.c (mouse_get_pos): Likewise.
19315 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19316 * w32gui.h (Time): Define by including "systime.h" rather than by
19317 declaring it ourselves. (Bug#8664)
19319 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19320 * image.c (clear_image_cache): Likewise.
19322 * term.c (term_mouse_position): Don't assume time_t wraparound.
19324 Be more systematic about user-interface timestamps.
19325 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19326 and sometimes 'EMACS_UINT', to represent these timestamps.
19327 This change causes it to use 'Time' uniformly, as that's what X uses.
19328 This makes the code easier to follow, and makes it easier to catch
19329 integer overflow bugs such as Bug#8664.
19330 * frame.c (Fmouse_position, Fmouse_pixel_position):
19331 Use Time, not unsigned long, for user-interface timestamps.
19332 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19333 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19334 * keyboard.h (last_event_timestamp): Likewise.
19335 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19336 * menu.h (xmenu_show): Likewise.
19337 * term.c (term_mouse_position): Likewise.
19338 * termhooks.h (struct input_event.timestamp): Likewise.
19339 (struct terminal.mouse_position_hook): Likewise.
19340 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19341 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19342 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19343 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19344 what it was before.
19345 * menu.h, termhooks.h: Include "systime.h", for Time.
19347 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19348 Don't assume that the difference between two unsigned long values
19349 can fit into an integer. At this point, we know button_down_time
19350 <= event->timestamp, so the difference must be nonnegative, so
19351 there's no need to cast the result if double-click-time is
19352 nonnegative, as it should be; check that it's nonnegative, just in
19353 case. This bug is triggered when events are more than 2**31 ms
19354 apart (about 25 days). (Bug#8664)
19356 * xselect.c (last_event_timestamp): Remove duplicate decl.
19357 (x_own_selection): Remove needless cast to unsigned long.
19359 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19360 that always fit in int. Use a sentinel instead of a counter, to
19361 avoid a temp and to allay GCC's concerns about possible int overflow.
19362 * frame.h (struct frame): Use int for menu_bar_items_used
19363 instead of EMACS_INT, since it always fits in int.
19365 * menu.c (grow_menu_items): Check for int overflow.
19367 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19369 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19370 Before, the code was not consistent. These values cannot exceed
19371 2**31 - 1 so there's no need to make them unsigned.
19372 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19373 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19374 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19376 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19378 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19379 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19380 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19381 presumably because the widths might not match.
19383 * window.c (size_window): Avoid needless test at loop start.
19385 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19387 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19389 2011-05-12 Drew Adams <drew.adams@oracle.com>
19391 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19393 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19395 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19396 `width' to `bar_area_x' and `bar_area_width', respectively.
19397 (x_scroll_run): Take account of fringe background extension.
19399 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19400 Rename local vars `left' and `width' to `bar_area_x' and
19401 `bar_area_width', respectively.
19402 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19403 background extension.
19405 2011-05-10 Jim Meyering <meyering@redhat.com>
19407 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19409 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19411 * image.c (Finit_image_library): Return t for built-in image types,
19412 like pbm and xbm. (Bug#8640)
19414 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19416 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19418 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19420 * w32console.c (Fset_screen_color): Doc fix.
19421 (Fget_screen_color): New function.
19422 (syms_of_ntterm): Defsubr it.
19424 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19425 unlink the temporary file if Fcall_process didn't create it in the
19427 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19428 child process will be redirected to a file specified with `:file'.
19429 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19430 cue to call_process_cleanup not to close that handle.
19432 2011-05-07 Ben Key <bkey76@gmail.com>
19434 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19435 one of two shell specific rules, either bootstrap-temacs-CMD or
19436 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19437 to the previous implementation of the bootstrap-temacs rule.
19438 The bootstrap-temacs-CMD rule is similar to the previous
19439 implementation of the bootstrap-temacs rule except that it
19440 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19443 These changes, along with some changes to nt/configure.bat,
19444 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19445 earlier fix to add support for --cflags and --ldflags options
19446 that include quotes so that it works whether make uses cmd or
19449 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19451 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19452 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19454 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19455 a string. Handle both cases.
19456 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19457 (Fdbus_register_method): Use Qinvalid_function.
19459 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19461 * makefile.w32-in: Update dependencies.
19462 (LISP_H): Add inttypes.h and stdin.h.
19463 (PROCESS_H): Add unistd.h.
19465 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19467 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19468 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19470 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19472 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19474 * term.c (vfatal): Remove stray call to va_end.
19475 It's not needed and the C Standard doesn't allow it here anyway.
19477 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19478 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19480 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19483 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19485 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19487 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19489 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19491 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19493 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19494 * charset.c (Fdefine_charset_internal): Don't initialize
19495 charset.code_space[15]. The value was garbage, on hosts with
19496 32-bit int (Bug#8600).
19498 * lread.c (read_integer): Be more consistent with string-to-number.
19499 Use string_to_number to do the actual conversion; this avoids
19500 rounding errors and fixes some other screwups. Without this fix,
19501 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19502 (digit_to_number): Move earlier, for benefit of read_integer.
19503 Return -1 if the digit is out of range for the base, -2 if it is
19504 not a digit in any supported base. (Bug#8602)
19506 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19508 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19509 to match comment at start of function. This also removes a
19510 GCC warning about overflow in a 32+64-bit port.
19512 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19514 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19515 Reported by Stefan Monnier in
19516 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19517 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19518 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19520 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19521 (EMACS_UINTPTR): Likewise, with uintptr_t.
19523 * lisp.h: Prefer 64-bit EMACS_INT if available.
19524 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19525 on 32-bit hosts that have 64-bit int, so that they can access
19527 However, temporarily disable this change unless the temporary
19528 symbol WIDE_EMACS_INT is defined.
19530 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19532 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19533 This removes an assumption that EMACS_INT and long are the same
19534 width as pointers. The assumption is true for Emacs porting targets
19535 now, but we want to make other targets possible.
19536 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19537 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19538 In the rest of the code, change types of integers that hold casted
19539 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19540 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19541 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19542 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19543 No need to cast type when ORing.
19544 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19545 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19546 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19547 assume EMACS_INT is the same width as char *.
19548 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19549 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19550 Remove no-longer-needed casts.
19551 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19552 (xg_tool_bar_help_callback, xg_make_tool_item):
19553 Use EMACS_INTPTR to hold an integer
19554 that will be cast to void *; this can avoid a GCC warning
19555 if EMACS_INT is not the same width as void *.
19556 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19557 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19558 (current_message_1, set_message_1):
19559 Use a local to convert to proper width without a cast.
19560 * xmenu.c (dialog_selection_callback): Likewise.
19562 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19563 Also, don't assume VALBITS / RAND_BITS is less than 5,
19564 and don't rely on undefined behavior when shifting a 1 left into
19566 * lisp.h (get_random): Change signature to match.
19568 * lread.c (hash_string): Use size_t, not int, for hash computation.
19569 Normally we prefer signed values; but hashing is special, because
19570 it's better to use unsigned division on hash table sizes so that
19571 the remainder is nonnegative. Also, size_t is the natural width
19572 for hashing into memory. The previous code used 'int', which doesn't
19573 retain enough info to hash well into very large tables.
19574 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19576 * dbusbind.c: Don't possibly lose pointer info when converting.
19577 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19578 Use XPNTR rather than XHASH, so that the high-order bits of
19579 the pointer aren't lost when converting through void *.
19581 * eval.c (Fautoload): Don't double-shift a pointer.
19583 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

19617 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19618 Remove unused parameter `fildes'.
19619 * process.c (read_process_output, send_process): Don't pass it.
19621 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19623 Fix previous change: the library cache is defined in w32.c.
19624 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19625 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

19660 (w32_delayed_load): Move from image.c. When loading a library, record
19661 its filename in the :loaded-from property of the library id.

19667 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19668 instead of gnutls_record_check_pending.
19670 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19672 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19674 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19675 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19678 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19680 * xterm.c (x_set_frame_alpha): Do not set property on anything

19715 (Fcall_process_region): Ditto.
19717 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19719 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19720 rather than `XVECTOR (FOO)->size'.
19722 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19723 inttypes.h, as a gnulib replacement is used if it not available in
19726 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19728 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19729 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19730 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19732 * coding.c (coding_alloc_by_realloc): Error out if destination
19733 will grow beyond MOST_POSITIVE_FIXNUM.
19734 (decode_coding_emacs_mule): Abort if there isn't enough place in
19735 charbuf for the composition carryover bytes. Reserve an extra
19736 space for up to 2 characters produced in a loop.

19751 produced by %s or %c overflows available buffer space. (Bug#8545)
19753 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19755 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19790 Improve `doprnt' and its usage. (Bug#8545)
19791 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19792 `format_end'. Remove support for %l as a conversion specifier.
19793 Don't use xrealloc. Improve diagnostics when the %l size modifier
19794 is used. Update the commentary.
19796 * eval.c (verror): Simplify calculation of size_t.
19798 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19801 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19803 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19806 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19808 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19809 This makes this file independent of the recent pseudovector change.
19811 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19813 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19815 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19816 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19817 Remove unused local.
19818 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19820 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19821 GCC 4.6.0 optimizes based on type-based alias analysis.
19822 For example, if b is of type struct buffer * and v of type struct
19823 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19824 != &v->size, and therefore "v->size = 1; b->size = 2; return
19825 v->size;" must therefore return 1. This assumption is incorrect
19826 for Emacs, since it type-puns struct Lisp_Vector * with many other
19827 types. To fix this problem, this patch adds a new type struct
19828 vectorlike_header that documents the constraints on layout of vectors
19829 and pseudovectors, and helps optimizing compilers not get fooled
19830 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19831 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19832 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19834 (XSETPVECTYPE): Rewrite in terms of new macro.
19835 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19836 This is a bit clearer, and further avoids the possibility of
19837 undesirable aliasing.
19838 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19839 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19840 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19841 since Lisp_Subr is a special case (no "next" field).
19842 (ASIZE): Now uses header.size rather than size.
19843 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19844 to avoid the hassle of writing XVECTOR (foo)->header.size.
19845 (struct vectorlike_header): New type.
19846 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19847 object, to help avoid aliasing.
19848 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19849 (SUBRP): Likewise, since Lisp_Subr is a special case.
19850 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19851 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19852 (struct Lisp_Hash_Table): Combine first two members into a single
19853 struct vectorlike_header member. All uses of "size" and "next" members
19854 changed to be "header.size" and "header.next".
19855 * buffer.h (struct buffer): Likewise.
19856 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19857 * frame.h (struct frame): Likewise.
19858 * process.h (struct Lisp_Process): Likewise.
19859 * termhooks.h (struct terminal): Likewise.
19860 * window.c (struct save_window_data, struct saved_window): Likewise.
19861 * window.h (struct window): Likewise.
19862 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19863 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19864 * buffer.c (init_buffer_once): Likewise.
19865 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19867 * process.c (Fformat_network_address): Use local var for size,
19870 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19872 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19873 * data.c (atof): Remove decl; no longer used or needed.
19874 (digit_to_number): Move to lread.c.
19875 (Fstring_to_number): Use new string_to_number function, to be
19876 consistent with how the Lisp reader treats infinities and NaNs.
19877 Do not assume that floating-point numbers represent EMACS_INT
19878 without losing information; this is not true on most 64-bit hosts.
19879 Avoid double-rounding errors, by insisting on integers when
19880 parsing non-base-10 numbers, as the documentation specifies.
19881 * lisp.h (string_to_number): New decl, replacing ...
19882 (isfloat_string): Remove.
19883 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19884 (read1): Do not accept +. and -. as integers; this
19885 appears to have been a coding error. Similarly, do not accept
19886 strings like +-1e0 as floating point numbers. Do not report
19887 overflow for integer overflows unless the base is not 10 which
19888 means we have no simple and reliable way to continue.
19889 Break out the floating-point parsing into a new
19890 function string_to_number, so that Fstring_to_number parses
19891 floating point numbers consistently with the Lisp reader.
19892 (digit_to_number): Move here from data.c. Make it static inline.
19893 (E_CHAR, EXP_INT): Remove, replacing with ...
19894 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19895 (string_to_number): New function, replacing isfloat_string.
19896 This function checks for valid syntax and produces the resulting
19897 Lisp float number too. Rework it so that string-to-number
19898 no longer mishandles examples like "1.0e+". Use strtoumax,
19899 so that overflow for non-base-10 numbers is reported only when
19900 there's no portable and simple way to convert to floating point.
19902 * textprop.c (set_text_properties_1): Rewrite for clarity,
19903 and to avoid GCC warning about integer overflow.
19905 * intervals.h (struct interval): Use EMACS_INT for members
19906 where EMACS_UINT might cause problems. See
19907 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19908 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19909 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19911 (offset_intervals): Tell GCC not to worry about length overflow
19912 when negating a negative length.
19914 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19915 (overrun_check_free): Likewise.
19917 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19918 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19921 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19922 (gnutls_make_error): Rename local to avoid shadowing.
19923 (gnutls_emacs_global_deinit): ifdef out; not used.
19924 (Fgnutls_boot): Use const for pointer to readonly storage.
19925 Comment out unused local. Fix pointer signedness problems.
19927 * lread.c (openp): Don't stuff size_t into an 'int'.
19928 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19929 about possible signed overflow.
19931 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19932 (GDK_KEY_g): Don't define if already defined.
19933 (xg_prepare_tooltip): Avoid pointer signedness problem.
19934 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19936 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19937 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19939 * xfns.c (Fx_window_property): Simplify a bit,
19940 to make a bit faster and to avoid GCC 4.6.0 warning.
19941 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19943 * fns.c (internal_equal): Don't assume size_t fits in int.
19945 * alloc.c (compact_small_strings): Tighten assertion a little.
19947 Replace pEd with more-general pI, and fix some printf arg casts.
19948 * lisp.h (pI): New macro, generalizing old pEd macro to other
19949 conversion specifiers. For example, use "...%"pI"d..." rather
19950 than "...%"pEd"...".
19951 (pEd): Remove. All uses replaced with similar uses of pI.
19952 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19953 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19954 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19955 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19956 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19957 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19958 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19960 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19961 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19962 * print.c (safe_debug_print, print_object): Likewise.
19963 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19965 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19966 avoiding the 0 flag, which is not portable.
19967 * process.c (Fmake_network_process): Use pI to avoid cast.
19968 * region-cache.c (pp_cache): Likewise.
19969 * xdisp.c (decode_mode_spec): Likewise.
19970 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19971 behavior on 64-bit hosts with printf arg.

19973 (x_stop_queuing_selection_requests): Likewise.
19974 (x_get_window_property): Don't truncate byte count to an 'int'
19977 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19978 here, since it parses constructs like leading '-' and spaces,
19979 which are not wanted; and it overflows with large numbers.
19980 Instead, simply match F[0-9]+, which is what is wanted anyway.
19982 * alloc.c: Remove unportable assumptions about struct layout.
19983 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19984 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19985 (allocate_vectorlike, make_pure_vector): Use the new macros,
19986 plus offsetof, to remove unportable assumptions about struct layout.
19987 These assumptions hold on all porting targets that I know of, but
19988 they are not guaranteed, they're easy to remove, and removing them
19989 makes further changes easier.
19991 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19992 This doesn't fix a bug but makes the code clearer.
19993 (string_overrun_cookie): Now const. Use initializers that
19994 don't formally overflow signed char, to avoid warnings.
19995 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19996 can cause Emacs to crash when string overrun checking is enabled.
19997 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19998 multiple of sizeof (EMACS_INT); it need not be, if
19999 alignof(EMACS_INT) < sizeof (EMACS_INT).
20000 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

20031 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20032 "cast to pointer from integer of different size".
20034 Improve doprnt and its use in verror. (Bug#8545)
20035 * doprnt.c (doprnt): Document the set of format control sequences
20036 supported by the function. Use SAFE_ALLOCA instead of always
20039 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20040 is one byte too soon. Don't use xrealloc; instead xfree and
20043 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20045 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

20051 parameters of `gnutls-boot' and documented those parameters in the
20052 docstring. Start callback support.
20053 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20054 unless a fatal error occurred. Call gnutls_alert_send_appropriate

20158 codepoint of an invalid character, to avoid displaying a bogus
20161 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20162 `error', not SYMBOL_NAME itself.
20164 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

20167 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20168 to `error' in error message about FINAL_CHAR argument. Make sure
20169 FINAL_CHAR is a character, and use %c when it is passed as
20170 argument to `error'.
20172 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20174 * s/ms-w32.h (localtime): Redirect to sys_localtime.
20176 * w32.c: Include <time.h>.

20240 * dispextern.h (struct redisplay_interface): Rename param
20241 to avoid shadowing.
20242 * termhooks.h (struct terminal): Likewise.

20359 * nsfont.m: Fixed bugs in ns_get_family and
20360 ns_descriptor_to_entity that were caused by using free to
20361 deallocate memory blocks that were allocated by xmalloc (via
20362 xstrdup). This caused Emacs to crash when compiled with
20363 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20364 --enable-checking=xmallocoverrun). xfree is now used to
20365 deallocate these memory blocks.

20379 (emacs_read, emacs_write): Remove check for negative size, as the
20380 Emacs source code has been audited now.
20381 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
20382 (emacs_read, emacs_write): Use it.
20383 * process.c (send_process): Adjust to the new signatures of
20384 emacs_write and emacs_gnutls_write. Do not attempt to store
20385 a byte offset into an 'int'; it might overflow.

20848 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20849 (overrun_check_free): Protoize.
20851 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20853 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20854 since callers should never pass a negative size.
20855 Change the signature to match that of plain 'read' and 'write'; see
20856 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20857 * lisp.h: Update prototypes of emacs_write and emacs_read.
20859 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20861 * xdisp.c (redisplay_window): Don't try to determine the character
20862 position of the scroll margin if the window start point w->startp
20863 is outside the buffer's accessible region. (Bug#8468)
20865 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20867 Fix write-region and its subroutines for buffers > 2GB.
20868 * fileio.c (a_write, e_write): Modify declaration of arguments and
20869 local variables to support buffers larger than 2GB.
20870 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20872 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20873 argument, local variables, and return value.
20875 * lisp.h: Update prototypes of emacs_write and emacs_read.
20877 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20879 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20881 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20883 Fix more problems found by GCC 4.6.0's static checks.
20885 * xdisp.c (vmessage): Use a better test for character truncation.
20887 * charset.c (load_charset_map): <, not <=, for optimization,
20888 and to avoid potential problems with integer overflow.
20889 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20890 * casetab.c (set_identity, shuffle): Likewise.
20891 * editfns.c (Fformat): Likewise.
20892 * syntax.c (skip_chars): Likewise.
20894 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20895 This also lets GCC 4.6.0 generate slightly better loop code.
20897 * callint.c (Fcall_interactively): <, not <=, for optimization.
20898 (Fcall_interactively): Count the number of arguments produced,
20899 not the number of arguments given. This is simpler and lets GCC
20900 4.6.0 generate slightly better code.
20902 * ftfont.c: Distingish more carefully between FcChar8 and char.
20903 The previous code passed unsigned char * to a functions like
20904 strlen and xstrcasecmp that expect char *, which does not
20905 conform to the C standard.
20906 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20907 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20908 char * when the C standard requires it.
20910 * keyboard.c (read_char): Remove unused var.
20912 * eval.c: Port to Windows vsnprintf (Bug#8435).
20913 Include <limits.h>.
20914 (SIZE_MAX): Define if the headers do not.
20915 (verror): Do not give up if vsnprintf returns a negative count.
20916 Instead, grow the buffer. This ports to Windows vsnprintf, which
20917 does not conform to C99. Problem reported by Eli Zaretskii.
20918 Also, simplify the allocation scheme, by avoiding the need for
20919 calling realloc, and removing the ALLOCATED variable.
20921 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20923 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20924 But keep the doprint source code for now, as we might revamp it
20925 and use it again (Bug#8435).
20926 * lisp.h (doprnt): Remove.
20927 * Makefile.in (base_obj): Remove doprnt.o.
20928 * deps.mk (doprnt.o): Remove.
20930 error: Print 32- and 64-bit integers portably (Bug#8435).
20931 Without this change, on typical 64-bit hosts error ("...%d...", N)
20932 was used to print both 32- and 64-bit integers N, which relied on
20933 undefined behavior.
20934 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20935 * lisp.h (error, verror): Mark as printf-like functions.
20936 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20937 Report overflow in size calculations when allocating printf buffer.
20938 Do not truncate output string at its first null byte.
20939 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20940 Truncate the output at a character boundary, since vsnprintf does not
20942 * charset.c (check_iso_charset_parameter): Convert internal
20943 character to string before calling 'error', since %c now has the
20945 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20946 overflow when computing char to be passed to 'error'. Do not
20947 pass Lisp_Object to 'error'; pass the integer instead.
20948 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20949 formatted with plain %d.
20951 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20953 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20955 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20957 * xterm.c (x_catch_errors): Remove duplicate declaration.
20959 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20961 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20963 2011-04-10 Jim Meyering <meyering@redhat.com>
20965 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20966 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20967 return ssize_t not "int", and use size_t as the buffer length.
20968 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20969 * gnutls.h: Update declarations.
20970 * process.c (read_process_output): Use ssize_t, to match.
20971 (send_process): Likewise.
20973 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20975 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20977 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20979 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20980 Use unsigned char, to match FcChar8 type definition.
20982 * xterm.c (handle_one_xevent):
20983 * xmenu.c (create_and_show_popup_menu):
20984 * xselect.c (x_decline_selection_request)
20985 (x_reply_selection_request): Avoid type-punned deref of X events.
20987 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20989 Fix some uses of `int' instead of EMACS_INT.
20990 * search.c (string_match_1, fast_string_match)
20991 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20992 (scan_buffer, find_next_newline_no_quit)
20993 (find_before_next_newline, search_command, Freplace_match)
20994 (Fmatch_data): Make some `int' variables be EMACS_INT.
20996 * xdisp.c (display_count_lines): 3rd argument and return value now
20997 EMACS_INT. All callers changed.
20998 (pint2hrstr): Last argument is now EMACS_INT.
21000 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21001 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21002 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21003 (decode_coding_utf_16, decode_coding_emacs_mule)
21004 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21005 (decode_coding_ccl, decode_coding_charset)
21006 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21007 (decode_coding_iso_2022, decode_coding_emacs_mule)
21008 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21009 <char_offset, last_offset>: Declare EMACS_INT.
21010 (encode_coding_utf_8, encode_coding_utf_16)
21011 (encode_coding_emacs_mule, encode_invocation_designation)
21012 (encode_designation_at_bol, encode_coding_iso_2022)
21013 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21014 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21016 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21017 (encode_invocation_designation): Last argument P_NCHARS is now
21019 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21020 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21022 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21025 * ccl.c (Fccl_execute_on_string): Declare some variables
21028 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21030 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21032 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21034 * process.c (Fformat_network_address): Doc fix.
21036 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21038 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21040 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21042 * keyboard.c (read_char): Call Lisp function help-form-show,
21043 instead of using internal_with_output_to_temp_buffer.
21044 (Qhelp_form_show): New var.
21045 (syms_of_keyboard): Use DEFSYM macro.
21047 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21049 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21051 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21053 * process.c (Flist_processes): Remove to Lisp.
21054 (list_processes_1): Delete.
21056 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21058 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21060 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21062 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21064 Fix more problems found by GCC 4.6.0's static checks.
21066 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21068 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21070 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21072 * xdisp.c (vmessage): Mark as a printf-like function.
21074 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21076 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21078 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21079 printf-like functions.
21080 (tiff_load): Add casts to remove these marks before passing them
21081 to system-supplied API.
21083 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21085 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21086 This avoids several warnings with gcc -Wstrict-overflow.
21087 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21088 directly, rather than having caller test rule sign. This avoids
21089 some unnecessary tests.
21090 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21091 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21092 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21094 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21095 (xfont_open): Avoid unnecessary tests.
21097 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21099 * composite.h, composite.c (composition_gstring_put_cache):
21100 Use EMACS_INT, not int, for length.

21103 breaking out part of COMPOSITION_DECODE_RULE.
21104 (COMPOSITION_DECODE_RULE): Use it.
21105 * composite.c (get_composition_id): Remove unused local vars,
21106 by using the new macro.
21108 * textprop.c (set_text_properties_1): Change while to do-while,
21109 since the condition is always true at first.
21111 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21112 (interval_deletion_adjustment): Return unsigned value.
21115 * process.c (list_processes_1, create_pty, read_process_output):

21125 (update_syntax_table): Use unsigned instead of int.
21127 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21128 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21129 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21131 * print.c (print_error_message): Avoid int overflow.
21133 * font.c (font_list_entities): Redo for clarity,
21134 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21136 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21137 (font_score): Avoid potential overflow in diff calculation.
21139 * fns.c (substring_both): Remove var that is set but not used.
21140 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21142 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21144 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21145 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21146 can always succeed if overflow has undefined behavior.
21148 * search.c (boyer_moore, wordify): Remove vars set but not used.
21149 (wordify): Omit three unnecessary tests.
21151 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21152 All callers changed. This avoids the need for an unused var.
21154 * casefiddle.c (casify_region): Remove var that is set but not used.
21156 * dired.c (file_name_completion): Remove var that is set but not used.
21158 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21160 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21161 (Finsert_file_contents): Remove unnecessary code checking fd.
21163 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21164 Check for integer overflow on size calculations.
21166 * buffer.c (Fprevious_overlay_change): Remove var that is set
21169 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21170 Remove vars that are set but not used.
21171 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21172 (timer_check_2): Mark vars as initialized.
21174 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21176 * image.c (lookup_image): Remove var that is set but not used.
21177 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21179 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21180 that are set but not used.
21182 * xfns.c (make_invisible_cursor): Don't return garbage
21183 if XCreateBitmapFromData fails (Bug#8410).
21185 * xselect.c (x_get_local_selection, x_handle_property_notify):
21186 Remove vars that are set but not used.
21188 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

21198 (map_tty_color) [!defined MSDOS]: Likewise.
21200 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21202 * coding.c: Remove vars that are set but not used.
21203 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21204 All callers changed.
21205 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21206 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21207 (decode_coding_charset): Remove vars that are set but not used.
21209 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21210 that is set but not used.
21212 * print.c (print_object): Remove var that is set but not used.
21214 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21215 The gnulib version avoids calling malloc in the usual case,
21216 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21217 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21218 * filelock.c (current_lock_owner): Likewise.
21219 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

21222 (emacs_readlink): New function.
21223 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21224 ../lib/careadlinkat.h.
21226 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21228 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21229 first non-nil return value).
21231 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21233 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21234 if not defined (Bug#8403).

21238 * xdisp.c (display_count_lines): Remove parameter `start',
21239 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

21243 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21244 and thereabouts. All callers changed.
21245 (get_per_char_metric): Remove parameter `f', unused since
21246 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21250 do not dereference NULL upon failed strdup
21251 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21252 (ns_get_family): Likewise.
21254 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21256 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

21293 (Fcommandp): Handle closures.
21294 (Feval): New `lexical' arg.
21295 (eval_sub): New function extracted from Feval. Use it almost

21304 but without exporting it to Lisp.
21306 * doc.c (Fdocumentation, store_function_docstring):
21307 * data.c (Finteractive_form): Handle closures.
21309 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21312 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21314 (exec_byte_code): New function extracted from Fbyte_code to handle new
21315 calling convention for byte-code-functions. Add new byte-codes.
21317 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21319 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21321 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21323 * xdisp.c (redisplay_internal): Fix prototype.
21325 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21327 * xdisp.c (SCROLL_LIMIT): New macro.
21328 (try_scrolling): Use it when setting scroll_limit.
21329 Limit scrolling to 100 screen lines.
21330 (redisplay_window): Even when falling back on "recentering",
21331 position point in the window according to scroll-conservatively,
21332 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21334 (try_scrolling): When point is above the window, allow searching
21335 as far as scroll_max, or one screenful, to compute vertical
21336 distance from PT to the scroll margin position. This prevents
21337 try_scrolling from unnecessarily failing when
21338 scroll-conservatively is set to a value slightly larger than the
21339 window height. Clean up the case of PT below the margin at bottom
21340 of window: scroll_max can no longer be INT_MAX. When aggressive
21341 scrolling is in use, don't let point enter the opposite scroll
21342 margin as result of the scroll.
21343 (syms_of_xdisp) <scroll-conservatively>: Document the
21344 threshold of 100 lines for never-recentering scrolling.
21346 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21348 * dispextern.h (move_it_by_lines):
21349 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21350 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21351 (message_log_check_duplicate): Remove parameters `prev_bol' and
21352 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21353 (redisplay_internal): Remove parameter `preserve_echo_area',
21354 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21356 * indent.c (Fvertical_motion):
21357 * window.c (window_scroll_pixel_based, Frecenter):
21358 Don't pass `need_y_p' to `move_it_by_lines'.
21360 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21362 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21363 steal a few bits to be more compact.
21364 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21365 Remove unneeded casts.
21367 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21369 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21371 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21372 binding" message (bug#7967).
21374 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21376 Fix more problems found by GCC 4.6.0's static checks.
21378 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21379 Remove unused local var.
21381 * editfns.c (Fmessage_box): Remove unused local var.
21383 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21384 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21385 Omit unused local vars.
21386 * window.c (shrink_windows): Omit unused local var.
21387 * menu.c (digest_single_submenu): Omit unused local var.
21388 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21389 Omit unused local var.
21391 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21392 Don't assume string length fits in int.
21393 (keyremap_step, read_key_sequence): Use size_t for sizes.
21394 (read_key_sequence): Don't check last_real_key_start redundantly.
21396 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21397 instead of alloca (Bug#8344).
21399 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21400 (Fbacktrace_frame): Don't assume nframes fits in int.
21402 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21404 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21407 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21409 * cm.c (calccost): Turn while-do into do-while, for clarity.
21411 * keyboard.c (syms_of_keyboard): Use the same style as later
21412 in this function when indexing through an array. This also
21413 works around GCC bug 48267.
21415 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21417 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21419 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21420 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21422 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21423 This avoids undefined behavior on integer overflow, and is a bit
21424 more convenient anyway since it is compared to a size_t variable.
21426 Variadic C functions now count arguments with size_t, not int.
21427 This avoids an unnecessary limitation on 64-bit machines, which
21428 caused (substring ...) to crash on large vectors (Bug#8344).
21429 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21430 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21431 All variadic functions and their callers changed accordingly.
21432 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21434 * editfns.c (general_insert_function): Likewise.
21435 * eval.c (struct backtrace.nargs, interactive_p)
21436 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21437 (funcall_lambda, mark_backtrace): Likewise.
21438 * fns.c (concat): Likewise.
21439 * frame.c (x_set_frame_parameters): Likewise.
21440 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21441 0 if not found, not -1. All callers changed.
21443 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21444 (stack_copy_size): Now size_t, not int.
21445 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21447 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21449 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21450 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21451 All callers changed.
21453 * lisp.h (multibyte_char_to_unibyte):
21454 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21455 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21456 * character.h (CHAR_TO_BYTE8):
21457 * cmds.c (internal_self_insert):
21458 * editfns.c (general_insert_function):
21459 * keymap.c (push_key_description):
21460 * search.c (Freplace_match):
21461 * xdisp.c (message_dolog, set_message_1): All callers changed.
21463 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21465 * keyboard.c (safe_run_hook_funcall): New function.
21466 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21467 don't set the hook to nil, but remove the offending function instead.
21468 (Qcommand_hook_internal): Remove, unused.
21469 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21470 Vcommand_hook_internal.
21472 * eval.c (enum run_hooks_condition): Remove.
21473 (funcall_nil, funcall_not): New functions.
21474 (run_hook_with_args): Call each function through a `funcall' argument.
21475 Remove `cond' argument, now redundant.
21476 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21477 (Frun_hook_with_args_until_failure): Adjust accordingly.
21478 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21480 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21482 * dispextern.h (string_buffer_position): Remove declaration.
21484 * print.c (strout): Remove parameter `multibyte', unused since
21485 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21487 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21488 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21489 All callers changed.
21491 * w32.c (_wsa_errlist): Use braces for struct initializers.
21493 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21494 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21495 All callers changed.
21496 (string_buffer_position): Likewise. Also, make static (it's never
21497 used outside xdisp.c).
21498 (cursor_row_p): Remove parameter `w', unused since
21499 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21501 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21502 All callers changed.
21504 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21506 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21512 (ns_update_auto_hide_menu_bar): New functions.
21513 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

21517 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21519 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21521 * nsmenu.m (runDialogAt): Remove argument to timer_check.
21523 2011-03-27 Glenn Morris <rgm@gnu.org>
21525 * syssignal.h: Replace RETSIGTYPE with void.
21526 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
21527 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
21528 Replace SIGTYPE with void everywhere.
21529 * s/usg5-4-common.h (SIGTYPE): Remove definition.

21532 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21534 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21535 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21537 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21539 * w32.c (read_unc_volume): Use parameter `henum', instead of
21540 global variable `wget_enum_handle'.
21542 * keymap.c (describe_vector): Remove parameters `indices' and
21543 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21546 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21548 * keyboard.c (timer_check): Remove parameter `do_it_now',
21549 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21550 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21551 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
21553 * keyboard.c (read_char):
21554 * w32menu.c (w32_menu_display_help):
21555 * xmenu.c (show_help_event, menu_help_callback):
21556 Adjust calls to `show_help_echo'.
21558 * gtkutil.c (xg_maybe_add_timer):
21559 * keyboard.c (readable_events):
21560 * process.c (wait_reading_process_output):
21561 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21563 * insdel.c (adjust_markers_gap_motion):
21564 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
21565 (gap_left, gap_right): Don't call it.
21567 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
21569 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
21570 incurred during fontification.

21614 Don't pass uninitialized region to CombineRgn.
21616 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
21618 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
21619 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
21620 (Fx_close_connection): Remove unused variable `i'.

21638 2011-03-23 Julien Danjou <julien@danjou.info>
21640 * term.c (Fsuspend_tty, Fresume_tty):
21641 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21642 * window.c (temp_output_buffer_show):

21648 * cmds.c (internal_self_insert):
21649 * callint.c (Fcall_interactively):
21650 * buffer.c (Fkill_all_local_variables):
21651 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21653 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21654 unconditionally since it does the check itself.
21656 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21658 Fix more problems found by GCC 4.5.2's static checks.
21660 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21661 the first time through the loop, since we know p0 < p1 then.
21662 This also avoids a gcc -Wstrict-overflow warning.
21664 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21665 leading to a memory leak, possible in functions like
21666 load_charset_map_from_file that can allocate an unbounded number
21667 of objects (Bug#8318).
21669 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21670 that could (at least in theory) be that large.
21672 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21673 This is less likely to overflow, and avoids undefined behavior if
21674 overflow does occur. All callers changed. Use strtoul to scan
21675 for the unsigned long integer.
21676 (pint2hrstr): Simplify and tune code slightly.
21677 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21679 * scroll.c (do_scrolling): Work around GCC bug 48228.
21680 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21682 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21683 This also avoids a warning with gcc -Wstrict-overflow.
21684 (validate_x_resource_name): Simplify count usage.
21685 This also avoids a warning with gcc -Wstrict-overflow.
21687 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21690 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21692 * process.c (Fmake_network_process): Use socklen_t, not int,
21693 where POSIX says socklen_t is required in portable programs.
21694 This fixes a porting bug on hosts like 64-bit HP-UX, where
21695 socklen_t is wider than int (Bug#8277).
21696 (Fmake_network_process, server_accept_connection):
21697 (wait_reading_process_output, read_process_output):
21700 * process.c: Rename or move locals to avoid shadowing.
21701 (list_processes_1, Fmake_network_process):
21702 (read_process_output_error_handler, exec_sentinel_error_handler):
21703 Rename or move locals.
21704 (Fmake_network_process): Define label "retry_connect" only if needed.
21705 (Fnetwork_interface_info): Fix pointer signedness.
21706 (process_send_signal): Add cast to avoid pointer signedness problem.
21707 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21708 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21710 Make tparam.h and terminfo.c consistent.
21711 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21712 Include tparam.h instead, since it declares them.
21713 * cm.h (PC): Remove extern decl; tparam.h now does this.
21714 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21715 * terminfo.c: Include tparam.h, to check interfaces.
21716 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21717 (tparam): Adjust signature to match interface in tparam.h;
21718 this removes some undefined behavior. Check that outstring and len
21719 are zero, which they always are with Emacs.
21720 * tparam.h (PC, BC, UP): New extern decls.
21722 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21723 (xftfont_open): Rename locals to avoid shadowing.
21725 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21726 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21727 (OTF_TAG_SYM): Omit macro if not needed.
21728 (ftfont_list): Remove unused local.
21729 (get_adstyle_property, ftfont_pattern_entity):
21730 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21731 Rename locals to avoid shadowing.
21733 * xfont.c (xfont_list_family): Mark var as initialized.
21735 * xml.c (make_dom): Now static.
21737 * composite.c (composition_compute_stop_pos): Rename local to

21774 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21776 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21777 This should get cleaned up, so that child_setup has the
21778 same signature on all platforms.

21942 (Fmemory_limit): Cast sbrk's returned value to char *.
21944 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21950 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21951 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21952 to use the following functions instead of these macros.
21953 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21954 EMACS_INT, since callers assume the returned value fits in int.
21955 (upcase1): Likewise, for UPCASE_TABLE.
21956 (uppercasep, lowercasep, upcase): New static inline functions.
21957 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21967 (regex_compile, re_match_2_internal): Mark locals as initialized.
21968 (RETALLOC_IF): Define only if needed.
21969 (WORDCHAR_P): Likewise. This one is never needed, but is used
21970 only in a comment talking about a compiler bug, so put inside
21971 the #if 0 of that comment.
21972 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21973 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22000 New macros, so that the caller can use some names other than
22001 gcpro1, gcpro2, etc.
22002 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22004 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22005 argument, for consistency with GCPRO2_VAR, etc: it is now the
22006 prefix of the variable, not the variable itself. All uses
22008 * dired.c (directory_files_internal, file_name_completion):
22009 Rename locals to avoid shadowing.
22011 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22012 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22013 dired.c's scmp function, had undefined behavior.
22014 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22015 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22016 * buffer.h: ... to here, because these macros use current_buffer,
22017 and the new implementation with inline functions needs to have
22018 current_buffer in scope now, rather than later when the macros
22020 (downcase, upcase1): New static inline functions.
22021 (DOWNCASE, UPCASE1): Reimplement using these functions.
22022 This avoids undefined behavior in expressions like
22023 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22024 from race conditions in accessing the global variables
22025 case_temp1 and case_temp2.
22026 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22027 * lisp.h (case_temp1, case_temp2): Remove their decls.
22028 * character.h (ASCII_CHAR_P): Move from here ...
22029 * lisp.h: ... to here, so that the inline functions mentioned
22030 above can use them.
22032 * dired.c (directory_files_internal_unwind): Now static.
22034 * fileio.c (file_name_as_directory, directory_file_name):

22037 (file_name_as_directory): Use const pointers when appropriate.
22038 (Fexpand_file_name): Likewise. In particular, newdir might
22039 point at constant storage, so make it a const pointer.
22040 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22041 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22043 (Fset_file_times, Finsert_file_contents, auto_save_error):

22048 to avoid shadowing.
22050 * marker.c (bytepos_to_charpos): Remove; unused.
22052 * lisp.h (verify_bytepos, count_markers): New decls,
22053 so that gcc does not warn that these functions aren't declared.
22055 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22056 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22057 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22058 (copy_text): Remove unused local var.
22060 * filelock.c (within_one_second): Now static.
22061 (lock_file_1): Rename local to avoid shadowing.
22063 * buffer.c (fix_overlays_before): Mark locals as initialized.
22064 (fix_start_end_in_overlays): Likewise. This function should be
22065 simplified by using pointers-to-pointers, but that's a different
22067 (switch_to_buffer_1): Now static.
22068 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22069 (report_overlay_modification): Rename locals to avoid shadowing.
22071 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22072 Fix pointer signedness issue.
22073 (sys_subshell): Mark local as volatile if checking for lint,
22074 to suppress a gcc -Wclobbered warning that does not seem to be right.
22075 (MAXPATHLEN): Define only if needed.
22077 * process.c (serial_open, serial_configure): Move decls from here ...
22078 * systty.h: ... to here, so that they can be checked.
22080 * fns.c (get_random, seed_random): Move extern decls from here ...
22081 * lisp.h: ... to here, so that they can be checked.
22083 * sysdep.c (reset_io): Now static.

22089 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22090 (DENSE_TABLE_SIZE): Remove; unused.
22091 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22092 (describe_map_tree):
22093 Rename locals to avoid shadowing.
22095 * keyboard.c: Declare functions static if they are not used elsewhere.
