1 2013-02-16 Eli Zaretskii <eliz@gnu.org>
3 * w32.c (set_errno): Reset h_errno and don't set it to any other
4 value. Set errno instead.
5 (check_errno): Reset h_errno.
6 (sys_socket, socket_to_fd, sys_bind, sys_connect)
7 (sys_gethostname, sys_getservbyname, sys_getpeername)
8 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
9 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
11 (sys_gethostbyname): Set h_errno only errors detected.
13 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
15 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
17 2013-02-15 Eli Zaretskii <eliz@gnu.org>
19 * keyboard.c (read_char): Fix calculation of auto-save time out
20 when auto-save-timeout is less than 4. (Bug#13720)
22 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
23 time. Improve diagnostics in DebPrint. (Bug#13546)
25 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
26 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
27 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
28 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
29 make sure errno is set to an appropriate value. (Bug#13546)
30 (socket_to_fd): Add assertion against indexing fd_info[] with a
31 value that is out of bounds.
32 (sys_accept): If fd is negative, do not set up the child_process
33 structure for reading.
35 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
37 * composite.c (fill_gstring_header): Remove useless prototype.
39 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
40 * print.c (PRINTDECLARE, print_object):
41 * search.c (compile_pattern, fast_looking_at, search_buffer):
42 (simple_search, boyer_moore, Freplace_match):
43 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
44 (get_overlay_arrow_glyph_row, display_mode_element):
45 (decode_mode_spec_coding, message3):
46 * xfaces.c (face_at_string_position): Use bool for booleans.
49 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
51 Fix AIX port (Bug#13650).
52 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
53 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
54 was #undeffed earlier, so it cannot be used as a macro here.
55 Use the constant and not the macro.
57 2013-02-15 Eli Zaretskii <eliz@gnu.org>
59 * w32proc.c (new_child): If no vacant slots are found in
60 child_procs[], make another pass looking for slots whose process
61 has exited or died. (Bug#13546)
63 * w32.c (sys_pipe): When failing due to file descriptors above
64 MAXDESC, set errno to EMFILE.
65 (_sys_read_ahead): Update cp->status when failing to read serial
66 communications input, so that the status doesn't stay at
67 STATUS_READ_IN_PROGRESS. (Bug#13546)
69 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
71 * gtkutil.c (tb_size_cb): New function.
72 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
74 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
76 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
79 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
81 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
83 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
85 * font.c (font_range): Add pos_byte argument. Adjust comment
87 * font.h (font_range): Adjust prototype.
88 * composite.c (autocmp_chars): Pass byte position to font_range.
89 Break long line. Remove useless prototype and format comment.
91 2013-02-13 Glenn Morris <rgm@gnu.org>
93 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
95 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
97 Improve AIX port some more (Bug#13650).
98 With this, it should be as good as it was in 23.3, though it's
99 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
100 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
101 * unexaix.c (start_of_text): Remove.
102 (_data, _text): Declare as char[], not int, as AIX manual suggests.
103 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
104 (orig_load_scnptr, orig_data_scnptr):
105 Now off_t, not long, since they are file offsets.
106 (make_hdr): Use _data, not start_of_data ().
107 This is the key part of the fix.
108 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
109 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
111 * pre-crt0.c (data_start): Initialize to 1.
112 This ports to compilers that optimize the external declaration
113 'int x = 0;' as if it were 'int x;' to shrink the executable.
115 Improve AIX port (Bug#13650).
116 This doesn't fix the bug, but it makes progress: Emacs builds now.
117 * unexaix.c: Include inttypes.h, stdarg.h.
118 (report_error, report_error_1): Mark as _Noreturn.
119 (report_error): Don't report the wrong errno.
120 (report_error_1): Now varargs. All callers changed.
121 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
122 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
123 (write_ptr): Use %p to print address rather than %lx and a cast
124 to unsigned long. Grow buffer a bit, to be safer.
126 2013-02-13 Eli Zaretskii <eliz@gnu.org>
128 * bidi.c (bidi_resolve_neutral): After finding the next
129 non-neutral character, accept NEUTRAL_ON type as well, because
130 directional control characters, such as LRE and RLE, have their
131 type converted to that by bidi_resolve_weak. This avoids aborts
132 when LRE/RLE follows a run of neutrals.
133 (bidi_move_to_visually_next): Assert that return value of
134 bidi_peek_at_next_level is non-negative. Negative values will
137 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
139 Minor getenv-related fixes.
140 * callproc.c (Fcall_process_region) [!DOS_NT]:
141 Avoid unnecessary duplicate call to getenv.
142 * callproc.c (init_callproc):
143 * dispnew.c (init_display):
144 * sysdep.c (sys_subshell):
145 Omit unnecessary cast of getenv or egetenv.
147 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
149 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
152 2013-02-12 Eli Zaretskii <eliz@gnu.org>
154 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
156 (display_line): Set w->region_showing to the value of
157 it->region_beg_charpos, not to -1. This fixes redisplay
158 optimization when cursor is moved up after M->. (Bug#13623)
160 (try_scrolling): Scroll text up more if point is too close to ZV
161 and inside the scroll margin. This makes sure point is moved
162 outside the scroll margin in these cases.
164 * window.h (struct window): region_showing can no longer be
167 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
169 Tune by using memchr and memrchr.
170 * doc.c (Fsnarf_documentation):
171 * fileio.c (Fsubstitute_in_file_name):
172 * search.c (find_newline, scan_newline):
173 * xdisp.c (pos_visible_p, display_count_lines):
174 Use memchr and memrchr rather than scanning byte-by-byte.
175 * search.c (find_newline): Rename from scan_buffer.
176 Omit first arg TARGET, as it's always '\n'. All callers changed.
178 Clean up read_key_sequence a tiny bit more.
179 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
180 (read_key_sequence): Remove unused locals.
182 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
184 Clean up read_key_sequence a bit; reread active keymaps after first event.
185 * keyboard.c (read_char, read_char_x_menu_prompt)
186 (read_char_minibuf_menu_prompt):
187 Replace nmaps+maps with a single `map' arg.
188 (follow_key): Operate on a single map.
189 (active_maps): New function.
190 (test_undefined): Also return true for nil bindings.
191 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
192 a single (composed) keymap. Remember `first_event' to choose the right
193 set of active keymaps. Recompute the set of keymaps after receiving
194 the first event. Remove GOBBLE_FIRST_EVENT.
195 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
196 * keyboard.h (read_char): Update declaration.
197 * lread.c (read_filtered_event): Adjust call to read_char.
199 2013-02-11 Eli Zaretskii <eliz@gnu.org>
201 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
202 Don't use the limitation on backwards movement when lines are truncated
203 in the window. (Bug#13675)
205 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
207 * marker.c (set_marker_internal): If desired position is passed
208 as a marker, avoid call to buf_charpos_to_bytepos.
209 * window.c (Fset_window_point): Omit redundant type checking.
210 (Fset_window_start): Likewise. Format comment.
211 (window_scroll_pixel_based): Use set_marker_restricted_both
212 with character and byte positions obtained from an iterator.
213 (Fset_window_configuration): Use set_marker_restricted_both.
214 * xdisp.c (message_dolog): Likewise.
216 2013-02-10 Eli Zaretskii <eliz@gnu.org>
218 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
219 When text lines are longer than window's screen lines, don't move back
220 too far. This speeds up some redisplay operations. (Bug#13675)
222 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
224 * syntax.c (scan_sexps_forward): Fix byte position calculation
225 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
227 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
229 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
232 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
234 Minor hashing refactoring.
235 * fns.c (SXHASH_REDUCE): Move to lisp.h.
236 (sxhash_float): Return EMACS_UINT, for consistency with the other
238 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
239 non-static inline function and therefore can't use static vars.
240 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
241 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
242 with the other hash functions.
244 2013-02-09 Eli Zaretskii <eliz@gnu.org>
246 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
247 XXXXXX part of the temporary file pattern is not downcased even
248 when w32-downcase-file-names is non-nil. (Bug#13661)
250 * xdisp.c (decode_mode_spec): Remove handling of %t.
252 * msdos.c (careadlinkatcwd): Remove.
254 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
256 * lread.c (skip_dyn_bytes): New function (bug#12598).
257 (read1): Use it. Use getc instead of READCHAR to read bytes.
258 (load_each_byte): Remove. Update users.
260 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
262 * search.c (scan_buffer): Calculate end byte position just once.
263 (scan_newline): Do not recalculate start_byte.
264 (search_command): Use eassert.
265 * syntax.c (struct lisp_parse_state): New member location_byte.
266 (scan_sexps_forward): Record from_byte and avoid redundant
267 character to byte position calculation ...
268 (Fparse_partial_sexp): ... here. Break too long line.
270 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
272 * lisp.h (make_uninit_vector): New function.
273 * alloc.c (Fvector, Fmake_byte_code):
274 * ccl.c (Fregister_ccl_program):
275 * charset.c (Fdefine_charset_internal, define_charset_internal):
276 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
277 * composite.c (syms_of_composite):
278 * font.c (Fquery_font, Ffont_info, syms_of_font):

281 * indent.c (recompute_width_table):
282 * nsselect.m (clean_local_selection_data):
283 * syntax.c (init_syntax_once):
284 * w32unsubscribe.c (uniscribe_shape):
285 * window.c (Fcurrent_window_configuration):
286 * xfaces.c (Fx_family_fonts):
287 * xselect.c (selection_data_to_lisp_data): Use it.
289 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
291 * coding.c (Fdefine_coding_system_internal): Use AREF where
292 argument is known to be a vector.
293 * fns.c (Flocale_info): Likewise for ASET.
294 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
295 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
297 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
299 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
302 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
303 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
304 updateCollectionBehaviour.
306 * nsterm.m (NEW_STYLE_FS): Remove.
307 (ns_last_use_native_fullscreen): New variable.
308 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
309 (x_set_window_size): Do not take title bar and tool bar into account
310 if isFullscreen returns YES.
311 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
312 (check_native_fs): New function.
313 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
314 (ns_term_init): Remove NEW_STYLE_FS.
315 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
316 and tool bar if isFullscreen returns NO.
317 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
318 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
320 (window:willUseFullScreenPresentationOptions:): New method.
321 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
322 Hide toolbar if not enabled (Bug#13444).
323 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
324 Restore tool bar if enabled, hide it otherwise (Bug#13444).
325 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
326 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
327 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
328 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
329 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
330 (syms_of_nsterm): Add ns-use-native-fullscreen.
332 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
334 * fileio.c (Qchoose_write_coding_system): Now static.
336 2013-02-04 Eli Zaretskii <eliz@gnu.org>
338 * xdisp.c (window_buffer_changed): region_showing can be negative,
339 which still means region is being displayed.
340 (redisplay_internal): Resurrect code that forced redisplay of the
341 whole window when showing region and the mark has changed.
342 Record the new mark position to allow redisplay optimizations.
343 (display_line): If it->region_beg_charpos is non-zero, set the
344 window's region_showing member to -1. (Bug#13623) (Bug#13626)
346 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
347 not bitfield of 1 bit.
349 2013-02-03 Daniel Colascione <dancol@dancol.org>
351 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
352 daemon mode works on cygw32 when Emacs is installed and not just
355 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
357 Avoid file time stamp bug on MS-Windows (Bug#13149).
358 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
359 as FAT32 doesn't update time stamps when truncating them.
360 Also, check that a file time stamp is not a multiple of 100 ns;
361 this should catch all instances of the problem on MS-Windows,
362 as its native file system resolution is 100 ns or worse, and
363 checking for a non-multiple of 100 ns should impose only a small
364 overhead on systems with ns resolution.
366 2013-02-02 Eli Zaretskii <eliz@gnu.org>
368 Avoid encoding file names on MS-Windows when they need to be run
369 through dostounix_filename.
370 * w32.c (normalize_filename): Accept an additional argument
371 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
372 downcase it even if w32-downcase-file-names is non-nil.
373 (dostounix_filename): Accept an additional argument MULTIBYTE and
374 pass it to normalize_filename.
375 (emacs_root_dir): Adjust.
377 * msdos.h (dostounix_filename): Adjust prototype.
379 * w32.h (dostounix_filename): Adjust prototype.
381 * msdos.c (dostounix_filename): Accept an additional argument and
383 (init_environment): Adjust callers of dostounix_filename.
385 * fileio.c (Ffile_name_directory, file_name_as_directory)
386 (directory_file_name, Fexpand_file_name)
387 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
389 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
391 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
392 variables, as egetenv is case-insensitive for DOS_NT.
394 * dired.c (file_name_completion): Don't call Fdirectory_file_name
395 with an encoded file name.
397 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
398 Adjust calls to dostounix_filename.
400 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
402 * unexw32.c (unexec): Adjust call to dostounix_filename.
404 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
406 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
409 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
412 * callproc.c (Fcall_process): Make sure program name in PATH and
413 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
414 is passed to exec/spawnve, which fails unless the file-name
417 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
418 even if w32-quote-process-args is nil.
420 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
422 Fix timestamp bug when write-region appends nothing (Bug#13149).
423 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
424 the file's time stamp doesn't change if Emacs happens to write nothing
425 to the file, and on a buggy file system this could cause Emacs to
426 incorrectly infer that the file system doesn't have the bug.
427 Avoid this problem by inhibiting the inference in this case.
429 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
431 * window.h (struct window): Convert base_line_number, base_line_pos
432 and column_number_displayed members from Lisp_Object to ptrdiff_t.
433 Convert region_showing member from Lisp_Object to bitfield.
434 Remove sequence_number member. Adjust comments.
435 * window.c (sequence_number): Remove.
436 (make_window): Initialize column_number_displayed.
437 * print.c (print_object): Follow the printed representation of
438 frames and print window pointer to distinguish between windows.
439 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
440 * xdisp.c (wset_base_line_number, wset_base_line_pos)
441 (wset_column_number_displayed, wset_region_showing): Remove.
442 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
443 (try_scrolling, try_cursor_movement, redisplay_window)
444 (try_window_reusing_current_matrix, try_window_id, display_line)
445 (display_mode_lines, decode_mode_spec): Adjust users.
446 * .gdbinit (pwinx): Do not print sequence_number.
448 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
450 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
451 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
452 * dired.c: Include <fcntl.h>.
453 (open_directory): New function, which uses open and fdopendir
454 rather than opendir. DOS_NT platforms still use opendir, though.
455 (directory_files_internal, file_name_completion): Use it.
456 (file_attributes): New function, with most of the old Ffile_attributes.
457 (directory_files_internal, Ffile_attributes): Use it.
458 (file_attributes, file_name_completion_stat): First arg is now fd,
459 not dir name. All uses changed. Use fstatat rather than lstat +
461 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
462 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
463 (emacs_readlinkat): New function, with much of the old
464 Ffile_symlink_p, but with an fd argument for speed.
465 It uses readlinkat rather than careadlinkatcwd, so that it
466 need not assume the working directory.
467 (Ffile_symlink_p): Use it.
468 * filelock.c (current_lock_owner): Use emacs_readlinkat
469 rather than emacs_readlink.
470 * lisp.h (emacs_readlinkat): New decl.
471 (READLINK_BUFSIZE, emacs_readlink): Remove.
472 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
473 (emacs_norealloc_allocator, emacs_readlink): Remove.
474 This stuff is moved to fileio.c.
475 * w32.c (fstatat, readlinkat): New functions.
476 (careadlinkat): Don't check that fd == AT_FDCWD.

483 Move the last piece of choose_write_coding_system here. (Bug#13522)
484 (syms_of_fileio): Add choose-write-coding-system.
486 2013-01-30 Eli Zaretskii <eliz@gnu.org>
488 * w32.c (sys_open): Zero out the flags for the new file descriptor.
489 (sys_close): Zero out the flags for the file descriptor before
490 closing it. (Bug#13546)
492 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
493 (logon_network_drive, stat_worker, symlink, chase_symlinks):
494 Use CharNextExA and CharPrevExA to iterate over file names encoded in
497 * w32.c (w32_get_long_filename, init_environment, readlink):
498 Support file names encoded in DBCS codepages.
499 (readlink): Use the current file-name-coding-system, not the ANSI
500 codepage, to decode and handle targets of symlinks.
502 2013-01-28 Eli Zaretskii <eliz@gnu.org>
504 * w32.c (opendir): Now accepts a 'const char *'.
506 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
508 Remove obsolete redisplay code. See the discussion at
509 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
510 * dispnew.c (preemption_period, preemption_next_check): Remove.
511 (Vredisplay_preemption_period): Likewise.
512 (update_frame, update_single_window, update_window, update_frame_1):
513 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
514 used, following the 2012-06-22 change.
516 2013-01-25 Eli Zaretskii <eliz@gnu.org>
518 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
520 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
522 * font.c (num_fonts): Remove the leftover from old
523 debugging code. Adjust comment style here and there.

530 * w32.c (max_filename_mbslen): New function.
531 (normalize_filename, readdir): Use it to detect locales where ANSI
532 encoding of file names uses a double-byte character set (DBCS).
533 If a DBCS encoding is used, advance by characters using
534 CharNextExA, instead of incrementing a 'char *' pointer.
535 Use _mbslwr instead of _strlwr. (Bug#13515)
537 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
538 request of memory reservation to 1.7GB. (Bug#13065)
540 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
542 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
543 at check_extra_latin label. (Bug#13505)
545 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
547 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
548 Avoid redundant calls to strlen.
550 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
552 Drop async_visible and async_iconified fields of struct frame.
553 This is possible because async input is gone; for details, see
554 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
555 * frame.h (struct frame): Remove async_visible and async_iconified
556 members, convert garbaged to unsigned bitfield. Adjust comments.
557 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
558 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
559 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
560 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
561 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
563 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
564 properly. Likewise for obscured.
566 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
569 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
571 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
573 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
574 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
576 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
578 * xdisp.c (message2, message2_nolog): Remove functions.
579 (message3, message3_nolog): Extract nbytes and multibyteness directly
580 from the string. Change all callers.
581 (message3_nolog): Don't set message_enable_multibyte since set_message
582 will reset it anyway.
583 (message1, message1_nolog): Use message3.
584 (vmessage): Use a stack allocated buffer rather than f->message_buf.
585 (with_echo_area_buffer): Remove last two arguments. Update all callers.
586 (set_message): Drop all but the second arg, which has to be a string.
587 (set_message_1): Simplify now that we know that a1 is NULL and the
588 second arg is a string.
589 * frame.h (struct frame): Remove `message_buf' field.
590 Use glyphs_initialized_p instead.
591 (FRAME_MESSAGE_BUF): Remove macro.
592 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
593 * lisp.h (message2, message2_nolog): Remove declarations.
594 (message3, message3_nolog): Update declarations.
595 * keyboard.c (read_char_minibuf_menu_text)
596 (read_char_minibuf_menu_width): Remove vars.
597 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
598 to correctly handle multibyte strings.
599 * frame.c (delete_frame): Don't free message_buf any more.
600 * editfns.c (message_text, message_length): Remove vars.
601 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
602 * fileio.c (auto_save_error): Use message3 instead of message2.
603 * dispnew.c (adjust_frame_message_buffer): Remove function.
605 2013-01-23 Eli Zaretskii <eliz@gnu.org>
607 * w32term.c (w32fullscreen_hook): Account correctly for the screen
608 real estate used for the tool bar and the menu bar.
610 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
612 * insdel.c (prepare_to_modify_buffer): Force redisplay if
613 hidden buffer is prepared to modification (Bug#13164).
615 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
617 * window.h (struct window): Change window_end_valid member from
618 Lisp_Object to a bitfield. Adjust comments.
619 (wset_window_end_valid): Remove.
620 * window.c (adjust_window_count): Clear window_end_valid.
621 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
622 (Fwindow_line_height, set_window_buffer, Frecenter)
623 (Fsplit_window_internal, Fdelete_other_windows_internal)
624 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
625 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
626 * xdisp.c (check_window_end, reconsider_clip_changes)
627 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
628 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
629 (find_first_unchanged_at_end_row, try_window_id): Likewise.
631 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
633 * xdisp.c (mark_window_display_accurate): Simplify the loop
634 assuming that the only one of vchild, hchild or buffer window
635 slots is non-nil. Call mark_window_display_accurate_1 for
636 the leaf windows only.
637 (mark_window_display_accurate_1): Always assume leaf window.
640 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
642 * emacs.c (Qkill_emacs_hook): Now static.
644 * fileio.c (Finsert_file_contents): Simplify.
645 Remove unnecessary assignments and tests.
647 2013-01-21 Eli Zaretskii <eliz@gnu.org>
649 * w32.c (acl_set_file): Don't test for errors unless
650 set_file_security returns FALSE. Avoids spurious errors when
653 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
655 * fileio.c (Finsert_file_contents): Revert code introduced at
656 2013-01-18 in favor of the simpler and generally better fix.
657 Save stack space by removing 'buffer' and reusing 'read_buf'
660 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
662 * lisp.h (eabs): Define unconditionally (Bug#13419).
663 The old "#if !defined (eabs)" was an unnecessary revenant of back
664 when this macro was called "abs". Document 'eabs' better.
666 2013-01-19 Glenn Morris <rgm@gnu.org>
668 * fns.c (Frandom): Doc fix.
670 2013-01-19 Eli Zaretskii <eliz@gnu.org>
672 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
673 segfault when there are lots of overlays.
675 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
676 when there are lots of overlays.
677 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
678 for the details and a way to reproduce.
680 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
682 * fileio.c: Use O_APPEND to append.
683 This corresponds better to the natural interpretation of "append",
684 and avoids the need to open the output file twice, or to invoke
685 lseek when APPEND is neither nil nor a number.
686 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
687 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
688 file possibly twice, and lseeking to its end; this avoids the
689 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
690 at the same time: the combination is never needed and apparently
691 it doesn't work with DOS_NT.
693 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
694 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
696 Allow floating-point file offsets.
697 Problem reported by Vitalie Spinu in
698 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
699 * fileio.c (emacs_lseek): Remove.
700 (file_offset): New function.
701 (Finsert_file_contents, Fwrite_region): Use it.
703 2013-01-19 Chong Yidong <cyd@gnu.org>
705 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
706 aborting on Fsignal (Bug#13289).
708 2013-01-19 Eli Zaretskii <eliz@gnu.org>
710 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
711 set_file_security as failure due to insufficient privileges.
712 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
713 (fstat): Return owner and group like 'stat' and 'lstat' do.
715 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
717 Work around bug in CIFS and vboxsf file systems (Bug#13149).
718 The bug was observed on Ubuntu operating inside a virtual machine,
719 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
720 The workaround introduces a race condition on non-buggy hosts,
721 but it's an unlikely race and anyway there's a nearly identical
722 nearby race that can't be fixed.
723 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
725 (Fwrite_region): Test for file system time stamp bug.
726 (init_fileio): New function.
727 * lisp.h (init_fileio): Declare it.
728 * emacs.c (main): Call it.
730 * fileio.c (Finsert_file_contents): Simplify new diagnostic
731 and make it more consistent with other stat-failure diagnostics.
733 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
735 Fix crash when inserting data from non-regular files.
736 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
737 for the error description produced by valgrind.
738 * fileio.c (read_non_regular): Rename to read_contents.
739 Free Lisp_Save_Value object used to pass parameters.
740 (read_non_regular_quit): Rename to read_contents_quit.
741 (Finsert_file_contents): Redesign internal file reading loop to adjust
742 gap and end positions after each read and so help make_gap to work
743 properly. Do not signal an I/O error too early and so do not leave
744 not yet decoded characters in a buffer, which was the reason of
745 redisplay crash. Use list2 to build return value. Adjust comments.
747 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
749 Close a race when statting and reading files (Bug#13149).
750 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
751 This avoids a race if the file is renamed between stat and open.
752 This race is not the problem originally noted in Bug#13149;
753 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
755 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

762 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
763 * alloc.c (format_save_value): Rename to make_save_value.
764 (make_save_pointer): New function.
765 (record_xmalloc): Use make_save_pointer.
766 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
767 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
768 Change users of make_save_value to make_save_pointer.
769 Likewise for format_save_value and make_save_value.
771 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
773 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
774 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.

778 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
780 * alloc.c (free_save_value): Now static.
782 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
784 * keymap.c (map_keymap_internal): Use format_save_value.
785 (map_keymap_char_table_item): Adjust accordingly.
786 * fileio.c (non_regular_fd, non_regular_inserted)
787 (non_regular_nbytes): Remove.
788 (Finsert_file_contents): Convert trytry to ptrdiff_t.
789 Use format_save_value to pass parameters to read_non_regular.
790 (read_non_regular): Use XSAVE_ macros to extract parameters.
792 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
794 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
796 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
798 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
799 extraction from any Lisp_Save_Value slot. Add type checking.
800 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
801 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
802 * xselect.c: All users changed.
804 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
806 Some convenient bits to deal with Lisp_Save_Values.
807 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
808 (allocate_misc): Remove prototype.
809 (format_save_value): New prototype.

814 * editfns.c (save_excursion_save): Use format_save_value.
815 (save_excursion_restore): Use XSAVE_OBJECT.
817 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
819 Avoid needless casts with XSAVE_POINTER.
820 * alloc.c (mark_object) [GC_MARK_STACK]:
821 * dired.c (directory_files_internal_unwind):
822 * fileio.c (do_auto_save_unwind):
823 * gtkutil.c (pop_down_dialog):
824 * keymap.c (map_keymap_char_table_item):
825 * lread.c (load_unwind):
826 * nsmenu.m (pop_down_menu):
827 * print.c (print_object) [GC_MARK_STACK]:
828 * xfns.c (clean_up_file_dialog):
829 * xmenu.c (cleanup_widget_value_tree):
830 Omit casts between XSAVE_POINTER and a pointer type.
832 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
834 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
835 * eval.c (eval_sub): Protect `form' from being GCed before its
836 car and cdr becomes protected with the backtrace entry.
838 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
840 Make Lisp_Save_Value more versatile storage for up to four objects.
841 * lisp.h (toplevel): Enumeration to describe types of saved objects.
842 (struct Lisp_Save_Value): New layout. Adjust comments.

844 (XSAVE_INTEGER): Likewise.
845 (allocate_misc): Add prototype.
846 (free_misc): Likewise.
847 * alloc.c (allocate_misc): Now global.
848 (free_misc): Likewise. Adjust comment.
849 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
850 (free_save_value): Likewise.
851 (mark_object): Likewise.
852 * editfns.c (save_excursion_save): Pack everything within
853 Lisp_Save_Value and so avoid xmalloc.
854 (save_excursion_restore): Adjust to match new layout. Use free_misc
855 because we do not allocate extra memory any more. Add eassert.
856 * print.c (print_object): New code to print Lisp_Save_Value. Do not
857 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
858 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
859 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
860 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
862 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>
864 * nsfont.m (LCD_SMOOTHING_MARGIN): New define.
865 (nsfont_draw): Remove disabling of LCD smoothing.

869 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
871 Fix SIGDANGER handlers, for AIX (Bug#13408).
872 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
873 Move handlers here from emacs.c; they were out of place.
875 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
877 * xterm.c (syms_of_xterm): Adjust documentation for
878 scroll-bar-adjust-thumb-portion.
880 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
882 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
883 determine whether scroll bar thumb size should be adjusted or
884 not. Use variable for MOTIF.
886 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
889 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

898 (nsfont_open): Move block_input earlier. Add unblock_input before early
900 (nsfont_draw): Add block/unblock_input calls.
902 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
904 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
905 for old_charpos and old_bytepos.
907 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
909 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
910 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
911 Clear tzvalbuf_in_environ if this workaround is in effect.
912 Problem and fix reported by Kazuhiro Ito.
914 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
916 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):
917 Fix ambiguous doc string cross-reference(s).
919 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
920 doc string cross-reference(s).
922 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
923 string cross-reference(s).
925 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
927 Avoid unnecessary byte position calculation for the gap movement.
928 Since all users of move_gap do CHAR_TO_BYTE for other purposes
929 anyway, all of them should use move_gap_both instead.
930 * lisp.h (move_gap): Remove prototype.
931 * insdel.c (move_gap): Remove.
932 (move_gap_both): Add eassert.
933 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
934 * xml.c (parse_region): Likewise.
936 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
938 emacsclient -t should not suspend Emacs server (Bug#13387)
939 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
941 * term.c (init_tty): Use them instead of rolling our own code.
942 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
943 switches from 'signal' to 'pthread_sigmask', which is safer in
944 multithreaded applications.
945 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
946 which has already arranged for that.

1024 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1025 Display the newline glyph more unambiguously.
1027 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1029 * nsterm.m (ns_draw_underwave):
1030 * w32term.c (w32_draw_underwave):
1031 * xterm.c (x_draw_underwave): Make underwave look more triangular

1034 * nsterm.m (ns_draw_text_decoration):
1035 * w32term.c (x_draw_glyph_string):
1036 * xterm.c (x_draw_glyph_string): Don't use previous underline

1057 * term.c (tty_ins_del_lines):
1058 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1059 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1061 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1063 * w32.c (unsetenv): Set up the string passed to _putenv
1065 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1066 for the bug this caused.

1070 * coding.c (Qmac): Now static.
1072 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1074 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1075 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1090 (xg_update_menubar): Update title only if
1091 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1092 (xg_update_submenu): Skip tearoff only if
1093 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1094 (xg_initialize): Initialize xg_detached_menus only if
1095 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1097 * xterm.h (struct x_output): Surround handlebox_widget with
1098 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1099 toolbar_in_hbox is bool.
1101 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>

1122 SetEvent and WaitForSingleObject.
1124 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1126 Port EXTERNALLY_VISIBLE to Clang 3.2.
1127 * conf_post.h (__has_attribute): New macro.
1128 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1130 2012-12-27 Glenn Morris <rgm@gnu.org>
1132 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1133 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1135 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1137 * fileio.c (file_name_as_directory, directory_file_name):
1138 Accept an additional argument MULTIBYTE to indicate whether the input C
1139 came from a multibyte or a unibyte Lisp string; all callers
1140 adjusted. Don't assume the input string is always multibyte.
1142 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1143 don't ENCODE_FILE them, and return a unibyte string if the input
1145 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1146 don't assume the input strings will always be multibyte. If the
1147 input strings are multibyte, decode strings obtained from C
1150 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1152 * lisp.h (toplevel): Add two notices to the comment about
1153 defining a new Lisp data type.

1159 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1161 * keyboard.c (record_asynch_buffer_change): Initialize an event
1162 only if it's really needed.
1163 * frame.h (enum output_method): Remove output_mac member since
1164 it's a leftover from the deleted code.
1165 * frame.c (Fframep): Adjust user here ...
1166 * terminal.c (Fterminal_live_p): ... and here.
1167 * coding.c (Qmac): Now here because it's only used to denote
1168 end-of-line encoding type.
1169 (syms_of_coding): DEFSYM it.
1170 * frame.h (Qmac): Remove duplicated declaration.
1172 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1174 * window.c (select_window_1): Now static, since it's used only here.
1176 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1178 * window.c (window_body_cols): Subtract display margins from the
1179 window body width on TTYs as well. See
1180 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1181 for the original report.
1183 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1185 * xdisp.c (redisplay_window): Remove inner local variable
1186 because the outer shadowed one has the same meaning.
1187 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1189 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1190 (xg_create_tool_bar): Adjust users.
1192 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1194 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1195 * buffer.c (Fget_buffer_create): Use it to set compact field of
1196 struct buffer_text to avoid accessing an uninitialized value
1197 when compact_buffer is called for the first time.
1198 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1199 (Fset_buffer_modified_p): Use buffer_window_count to check
1200 whether the buffer is displayed in some window.
1201 * xdisp.c (message_dolog): Likewise.
1203 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1205 * w32.c (acl_set_file): If setting the file security descriptor
1206 fails, and the new DACL is identical to the existing one, silently
1207 return success. This fixes problems for users backing up their
1208 own files without having the necessary privileges for setting
1209 security descriptors.
1211 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1213 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1214 after WaitForSingleObject returns normally. This expedites reader
1215 thread shutdown when delete_child triggers it.
1216 (reap_subprocess): More accurate commentary for why we call
1217 delete_child only when cp->fd is negative.
1219 * w32.c (sys_close): Do not call delete_child on a subprocess
1220 whose handle is not yet closed. Instead, set its file descriptor
1221 to a negative value, so that reap_subprocess will call
1222 delete_child on that subprocess when its SIGCHLD arrives.
1223 This avoids closing handles used for communications between sys_select
1224 and reader_thread, which doesn't give sys_select a chance to
1225 notice that the process exited and invoke the SIGCHLD handler for
1228 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1230 * nsfns.m (Fns_do_applescript): Run event loop until script has
1231 been executed (Bug#12969).

1239 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1241 * w32term.c (w32fullscreen_hook): New function.
1242 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1244 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1246 * fileio.c (Finsert_file_contents): Doc fix.
1248 * w32proc.c (new_child, delete_child, find_child_pid): For a
1249 subprocess, consider its slot being in use as long as its process
1250 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1251 slot when a new process is started immediately after killing
1252 another one, without waiting enough time for the first process to
1253 be reaped and resources allocated for it be orderly freed.
1255 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1257 2012-12-21 Chong Yidong <cyd@gnu.org>
1259 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1261 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1263 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1265 * w32.c (get_name_and_id): Always pass NULL as the first argument
1266 of lookup_account_sid. Avoids crashes with UNC file names that
1267 refer to DFS domains, not to specific machine names. (Bug#12621)
1268 Remove now unused argument FNAME; all callers changed.
1269 (get_file_owner_and_group): Remove now unused argument FNAME; all
1272 2012-12-21 Chong Yidong <cyd@gnu.org>
1274 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1275 error for invalid chars, don't check for a nil return value.
1277 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1279 Avoid calls to CHAR_TO_BYTE if byte position is known.
1280 * editfns.c (make_buffer_string_both): Use move_gap_both.
1281 (Fbuffer_string): Use make_buffer_string_both.

1285 (charpos_to_bytepos): Remove.
1286 * fileio.c (Finsert_file_contents): Use move_gap_both.
1287 * search.c (Freplace_match): Likewise.
1288 * process.c (process_send_region): Likewise. Use convenient
1289 names for byte positions.
1290 * lisp.h (charpos_to_bytepos): Remove prototype.
1291 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1292 * insdel.c (move_gap): Likewise.

1300 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1301 (redisplay_internal): Don't bother selecting the frame to get the
1302 proper value of frame-local variables (bug#13225).
1304 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1306 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1307 Rename 4th argument since it may be buffer or string. Adjust comment.
1308 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1310 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1312 * coding.c (Fdetect_coding_region): Do not check start and end with
1313 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1314 (code_convert_region): Likewise.
1316 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1318 * w32.c (acl_get_file, acl_set_file): Run the file name through
1319 map_w32_filename, and resolve any symlinks in the file name, like
1321 (acl_set_file): Call revert_to_self, if any privileges were
1324 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

1327 ($(BLD)/w32.$(O)): Update dependencies.
1329 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1331 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1332 propagate redisplay's scrolling (if any) to the right window.
1333 (redisplay_internal): Use ensure_selected_frame.
1334 (display_mode_lines): Complete last fix.
1335 * window.c (select_window_1): New func, extracted from select_window.
1336 (select_window): Use it.
1337 * window.h (select_window_1): Declare.

1363 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1365 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1366 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1367 for some of that bug's symptoms can now cause Emacs to abort.
1368 Remove the workaround.
1369 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1370 The bug that caused SIGCHLD to get lost has been fixed, and the
1371 workaround for it can now cause Emacs to abort.
1373 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1375 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1376 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1377 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1417 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1418 asynchronous subprocess, record the name of the input file name,
1420 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1421 delete the file, record it as pending deletion when the subprocess
1424 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1426 * editfns.c [HAVE_PWD_H]: Include grp.h.
1428 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1430 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1432 Fix permissions bugs with setgid directories etc. (Bug#13125)
1433 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1434 to mark it as a placeholder. The old value was often wrong.
1435 The only user of this attribute has been changed to use
1436 file-ownership-preserved-p instead, with its new group arg.
1437 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1444 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1446 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1447 try to get accurate owner and group information from NT file
1448 security APIs. This is to make most callers of 'stat' and
1449 'lstat', which don't need that information, much faster.
1451 * dired.c (Ffile_attributes) [WINDOWSNT]:
1452 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1453 owner and group information from 'lstat'.
1455 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1457 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1458 as that confuses set-auto-coding, so insist on the head-read
1459 returning the full 1024 bytes. Let lseek compute the tail offset;
1460 less work for us. Do not ignore I/O errors when reading the tail.
1462 * xdisp.c: Minor style fixes.
1463 (init_iterator): Hoist assignment out of if-expression.
1464 (markpos_of_region): Callers now test for sign, not for -1.

1483 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1484 files, fixing a regression from 24.2.
1485 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1487 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1489 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1490 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1491 Remove unnecessary S_ISLNK test, as (contra the comments) this
1492 function can't copy symlinks. Improve quality of error message
1493 when attempting to copy files that are neither regular files nor

1506 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1507 the dumped Emacs is not a sparse file, greatly improving Cygwin
1508 "make bootstrap" performance.

1512 * inotify.c (inotify_callback): Generate an Emacs event for every
1513 incoming inotify event.
1515 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1517 * xdisp.c (handle_face_prop): Fix logic of computing
1518 it->start_of_box_run_p.
1519 (append_space_for_newline): If the glyph row is R2L, reset the
1520 iterator's end_of_box_run_p flag before prepending the space glyph.
1521 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1522 iterator's start_of_box_run_p flag before prepending the stretch.
1523 (append_glyph, produce_image_glyph, append_composite_glyph)
1524 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1525 left_box_line_p and right_box_line_p flags of the glyph for R2L
1526 glyph rows. (Bug#13011)
1528 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1533 * window.c (replace_buffer_in_windows_safely): Do nothing
1534 if buffer is not shown in a window.

1540 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1541 encoded_file_name, which is what it is.
1543 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1545 Consistently use marker_position and marker_byte_position.
1546 * fringe.c (Ffringe_bitmaps_at_pos):

1567 Windows file notification functionality unless WINDOWSNT.
1569 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1572 * w32fns.c (cache_system_info): Initialize the global hinst
1573 variable here so various initialization calls DTRT.
1575 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1576 (hinst): Remove unneeded extern declaration.
1577 (_start): Remove initialization of above variables; remove
1578 initialization of hinst, as cache_system_info now does that.
1580 * emacs.c (main): Call cache_system_info early in startup; we
1581 previously weren't calling it in Cygwin builds.
1583 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
1584 Teach the autoconf build system how to compile a Windows resource file
1585 and link it to Emacs.

1722 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1724 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

1726 * dbusbind.c (Fdbus_init_bus):
1728 * xterm.c (x_term_init):

1797 * frame.c (make_frame): Do not set window's buffer to t.
1798 * window.c (Fsplit_window_internal): Likewise. Previously it was
1799 used to indicate that the window is being set up. Now we use
1800 set_window_buffer for all new windows, so the condition in ...
1801 (Fset_window_buffer): ... is always true and can be removed.
1803 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1805 Convenient macro to check whether the buffer is hidden.
1806 * buffer.h (BUFFER_HIDDEN_P): New macro.

1819 * frame.h (x_char_width, x_char_height): Remove prototypes.

1833 * callproc.c, process.h (record_kill_process):
1834 New function, containing part of the old call_process_kill.
1835 (call_process_kill): Use it.
1836 This does not change call_process_kill's behavior.
1837 * process.c (Fdelete_process): Use record_kill_process to fix a
1838 race condition that could cause Emacs to lose track of a child.
1840 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1842 Avoid code duplication between prev_frame and next_frame.
1843 * frame.c (candidate_frame): New function. Add comment.

1846 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1848 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1849 fails, signal an error instead of continuing with an empty
1851 Encode expanded temp file pattern before passing it to mkstemp or
1854 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1855 Encode the file name before passing it to dostounix_filename, in
1856 case it will downcase it (under w32-downcase-file-names).
1859 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1861 Minor call-process cleanups.
1862 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1863 at the same time as other platforms, to simplify analysis.
1864 No need for fd0_volatile since we have synch_process_fd.
1865 Avoid needless emacs_close; arg is always negative.
1867 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1869 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

1882 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1883 members to a bitfields.
1885 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1887 Don't let call-process be a zombie factory (Bug#12980).
1888 Fixing this bug required some cleanup of the signal-handling code.
1889 As a side effect, this change also fixes a longstanding rare race
1890 condition whereby Emacs could mistakenly kill unrelated processes,
1891 and it fixes a bug where a second C-g does not kill a recalcitrant
1892 synchronous process in GNU/Linux and similar platforms.
1893 The patch should also fix the last vestiges of Bug#9488,
1894 a bug which has mostly been fixed on the trunk by other changes.
1895 * callproc.c, process.h (synch_process_alive, synch_process_death)
1896 (synch_process_termsig, sync_process_retcode):
1897 Remove. All uses removed, to simplify analysis and so that
1898 less consing is done inside critical sections.
1899 * callproc.c (call_process_exited): Remove. All uses replaced
1900 with !synch_process_pid.
1901 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1902 These take the role of what used to be in unwind-protect arg.
1904 (block_child_signal, unblock_child_signal):
1905 New functions, to avoid races that could kill innocent-victim processes.
1906 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1907 (call_process_kill): Record killed processes as deleted, so that
1908 zombies do not clutter up the system. Do this inside a critical
1909 section, to avoid a race that would allow the clutter.
1910 (call_process_cleanup): Fix code so that the second C-g works again
1911 on common platforms such as GNU/Linux.
1912 (Fcall_process): Create the child process in a critical section,
1913 to fix a race condition. If creating an asynchronous process,
1914 record it as deleted so that zombies do not clutter up the system.
1915 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1916 light of these changes. Omit unnecessary call to emacs_close
1917 before failure, as the unwind-protect code does that.
1918 * callproc.c (call_process_cleanup):
1919 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1920 * process.c (record_deleted_pid): New function, containing
1921 code refactored out of Fdelete_process.
1922 (Fdelete_process): Use it.
1923 (process_status_retrieved): Remove. All callers changed to use
1924 child_status_change.
1925 (record_child_status_change): Remove, folding its contents into ...
1926 (handle_child_signal): ... this signal handler. Now, this
1927 function is purely a handler for SIGCHLD, and is not called after
1928 a synchronous waitpid returns; the synchronous code is moved to
1929 wait_for_termination. There is no need to worry about reaping
1930 more than one child now.
1931 * sysdep.c (get_child_status, child_status_changed): New functions.
1932 (wait_for_termination): Now takes int * status and bool
1933 interruptible arguments, too. Do not record child status change;
1934 that's now the caller's responsibility. All callers changed.
1935 Reimplement in terms of get_child_status.
1936 (wait_for_termination_1, interruptible_wait_for_termination):
1937 Remove. All callers changed to use wait_for_termination.
1938 * syswait.h: Include <stdbool.h>, for bool.
1939 (record_child_status_change, interruptible_wait_for_termination):
1941 (record_deleted_pid, child_status_changed): New decls.
1942 (wait_for_termination): Adjust to API changes noted above.
1944 * bytecode.c, lisp.h (Qbytecode): Remove.
1945 No longer needed after 2012-11-20 interactive-p changes.
1947 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1949 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1950 the scroll margin, move point outside the margin. (Bug#13055)
1952 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1954 * gtkutil.c (my_log_handler): New function.
1955 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1957 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1959 * lisp.h (modify_region): Rename to...
1960 (modify_region_1): ...new prototype.
1961 * textprop.c (modify_region): Now static. Adjust users.
1962 * insdel.c (modify_region): Rename to...
1963 (modify_region_1): ...new function to work with current buffer.
1964 Adjust comment and users. Use true and false for booleans.
1966 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1968 * alloc.c (free_save_value): New function.
1969 (safe_alloca_unwind): Use it.
1970 * lisp.h (free_save_value): New prototype.
1971 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1973 (save_excursion_restore): Adjust to match saved data structure.
1974 Use free_save_value to offload some work from GC. Drop obsolete
1977 2012-12-03 Chong Yidong <cyd@gnu.org>
1979 * fileio.c (Vauto_save_list_file_name): Doc fix.
1981 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1983 * w32fns.c: Remove prototype of atof.
1984 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1986 (file_dialog_callback): Make it UINT_PTR.
1988 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1991 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1992 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1995 2012-12-03 Glenn Morris <rgm@gnu.org>
1997 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1999 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2001 Fix xpalloc confusion after memory is exhausted.
2002 * alloc.c (xpalloc): Comment fix.
2003 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2004 and signals an error, do not clear charset_table_size, as
2005 charset_table is still valid.
2006 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2008 Use execve to avoid need to munge environ (Bug#13054).
2009 * callproc.c (Fcall_process):
2010 * process.c (create_process):
2011 Don't save and restore environ; no longer needed.
2012 * callproc.c (child_setup):
2013 Use execve, not execvp, to preserve environ.
2015 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2017 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2019 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2021 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2022 display for sliced images (Bug#10500).
2024 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2026 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2028 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2029 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2031 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2033 * xdisp.c (window_outdated): Remove eassert since it hits
2034 some suspicious corner cases (see Bug#13007 and Bug#13012).
2035 (mode_line_update_needed): New function.
2036 (redisplay_internal, redisplay_window): Use it.

2038 (redisplay_internal, unwind_redisplay): Use it.
2039 (redisplay_internal): Move comment about buffer_shared...
2040 (buffer_shared_and_changed): ...near to its real use.
2042 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2044 * callproc.c (Fcall_process): Don't misreport vfork failure.
2046 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2048 * callproc.c (Fcall_process): Fix vfork portability problems.
2049 Do not assume that fd[0], count, filefd, and save_environ survive
2050 vfork. Fix bug whereby wrong errno value could be reported for
2051 pipe failure. Some minor cleanups, too, as follows. Move buf and
2052 bufsize to the context where they're needed. Change new_argv to
2053 be of type char **, as this is more convenient and avoids casts.
2054 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2055 Now local constants, not macros.
2057 2012-11-18 Kenichi Handa <handa@gnu.org>
2059 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2060 for the variable "f".
2062 2012-11-13 Kenichi Handa <handa@gnu.org>
2064 * font.c (font_unparse_xlfd): Exclude special characters from the
2065 generating XLFD name.

2090 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2091 highlighting on the frame was cleared. Prevents assertion
2092 violations when repeatedly clicking on the "Top" link of the
2093 "bread-crumbs" in Info buffers.

2107 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2108 between bpos_covered and bpos_max. This fixes cursor display when
2109 several display strings follow each other.
2111 * .gdbinit (pgx): If the glyph's object is a string, display the
2112 pointer to string data, rather than the value of the string object
2113 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2115 * indent.c (Fvertical_motion): If the starting position is covered
2116 by a display string, return to one position before that, to avoid
2117 overshooting it inside move_it_to. (Bug#12930)
2119 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2121 * frame.h (struct frame): Remove display_preempted member

2130 Drop unused pending_menu_activation member.
2131 * xterm.h (struct x_output): Drop outdated #if 0 code.
2132 Use bitfields for explicit_parent, asked_for_visible,
2133 has_been_visible and net_wm_state_hidden_seen members.

2144 * dired.c: Assume HAVE_DIRENT_H.
2145 (NAMLEN): Remove, replacing with ...
2146 (dirent_namelen): New function. All uses changed. Use the GNU macro
2147 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2148 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2149 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2150 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2152 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2153 * ndir.h: Rename to ../nt/inc/dirent.h.
2154 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2155 Do not include <dirent.h>; no longer needed.
2156 * w32.c: Include <dirent.h> rather than "ndir.h".
2158 2012-11-23 Chong Yidong <cyd@gnu.org>
2160 * xftfont.c (xftfont_open): Remove duplicate assignment.
2162 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2164 * alloc.c (Fgarbage_collect): Unblock input after clearing
2165 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2166 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2167 * msdos.c (IT_frame_up_to_date): Use it here...
2168 * w32term.c (w32_frame_up_to_date): ...here...
2169 * xterm.c (XTframe_up_to_date): ...and here...
2170 * nsterm.m (ns_frame_up_to_date): ...but not here.
2171 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2173 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2174 Do not check whether GC is in progress.
2176 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2178 * xdisp.c (window_buffer_changed): New function.
2179 (update_menu_bar, update_tool_bar): Use it to
2180 simplify large 'if' statements.

2182 'tail' and 'frame' local variables.
2184 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2186 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2187 with Windows system header.
2189 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2191 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2192 * alloc.c: Assume unistd.h exists.

2196 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2197 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2198 * w32.h (getcwd): Remove decl.
2200 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

2206 2012-11-21 Ken Brown <kbrown@cornell.edu>
2208 * emacs.c (main): Set the G_SLICE environment variable for all
2209 Cygwin builds, not just GTK builds. See
2210 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2212 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2214 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2215 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2216 Define for the MSVC compiler.
2218 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2220 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2221 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2222 dostounix_filename. Prevents crashes down the road, because
2223 dostounix_filename assumes it gets a unibyte string.
2224 Reported by Michel de Ruiter <michel@sentient.nl>, see
2225 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

2256 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2257 (syms_of_eval): Remove corresponding defsubr.
2258 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2260 2012-11-19 Daniel Colascione <dancol@dancol.org>
2262 * w32fns.c (Fx_file_dialog):
2263 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2264 cygwin_convert_file_name*.
2266 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2267 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2269 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2271 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2273 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2275 * w32select.c: Include w32common.h before w32term.h, so that
2276 windows.h gets included before w32term.h uses some of its
2277 features, see below.
2279 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2281 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2285 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2287 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2288 (ns_select): Return at once if events are held (Bug#12834).
2290 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2292 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2293 Needed following 2012-10-20 change. (Bug#12902)
2295 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2297 * w32proc.c (waitpid): Remove unused label get_result.
2299 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2301 * makefile.w32-in (SYSWAIT_H): New macro.
2302 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2303 ($(BLD)/sysdep.$(O)): Update dependencies.
2305 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2307 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2308 * callproc.c (relocate_fd): Assume F_DUPFD.
2309 * emacs.c, term.c (O_RDWR): Remove.
2310 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2311 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2312 * nsterm.m: Assume <fcntl.h> exists.
2313 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2314 (create_pty, Fmake_network_process, server_accept_connection)
2315 (wait_reading_process_output, init_process_emacs):
2317 (wait_reading_process_output): Put in a special case for WINDOWSNT
2318 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2319 It's not clear this is needed, but it's a more-conservative change.
2320 (create_process): Assume FD_CLOEXEC.
2321 (create_process, create_pty): Assume O_NOCTTY.
2322 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2323 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2324 Omit if not DOS_NT, since F_GETFL is not defined there.
2325 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2326 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2328 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2329 lack it, since gnulib guarantees this.
2330 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2332 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2334 * w32.c (faccessat): Pretend that directories have the execute bit
2335 set. Emacs expects that, e.g., in files.el:cd-absolute.
2337 * w32proc.c (create_child): Don't clip the PID of the child
2338 process to fit into an Emacs integer, as this is no longer a
2340 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2341 reaping only the process specified by PID argument, if that is
2342 positive. Use PID instead of dead_child to know which process to
2343 reap. Wait for the child to die only if WNOHANG is not in
2345 (sys_select): Don't set dead_child.
2347 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2348 as it is no longer needed.
2350 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2352 (record_child_status_change): Remove the setting of
2353 record_at_most_one_child for the !WNOHANG case.
2355 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2357 Fix problems in ns port found by static checking.
2358 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2359 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2360 not to process group.
2361 (ns_select): Use emacs_write, not write, as that's more robust
2362 in the presence of signals.
2363 (fd_handler:): Check for read errors.
2365 2012-11-16 Glenn Morris <rgm@gnu.org>
2367 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2369 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2371 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2373 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2375 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2376 use the same value of thread handle.
2377 (start_timer_thread): If the timer thread exited (due to error),
2378 clean up by closing the two handles it used. Duplicate the caller
2379 thread's handle here, so it gets duplicated only once, when
2380 launching the timer thread. Set priority of the timer thread, not
2382 (getitimer): Don't duplicate the caller thread's handle here.
2385 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2387 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2390 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2392 Remove no-longer-used pty_max_bytes variable.
2393 * process.c (pty_max_bytes): Remove; unused.
2394 (send_process): Do not set it.
2396 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2398 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2399 Update dependencies.
2401 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2403 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2404 This follows up on the 2012-09-29 patch that removed indirection
2405 for the 'function' field. Reported by Sergey Vinokurov in
2406 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2408 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2410 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2411 different name, as the MS runtime does not have such a function,
2412 and probably never will.) All callers changed. Ignore DIRFD
2413 value if PATH is an absolute file name, to match Posix spec
2414 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2417 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2419 * xdisp.c (echo_area_display, redisplay_internal):
2420 Omit redundant check whether frame_garbaged is set.
2422 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2424 Use faccessat, not access, when checking file permissions (Bug#12632).
2425 This fixes a bug that has been present in Emacs since its creation.
2426 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2427 which must set some sort of record. (Torek's bug report was against
2428 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2429 same common flaw.) See Torek's Usenet posting
2430 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2431 Posted: Fri Apr 8 14:18:56 1983.
2432 * Makefile.in (LIB_EACCESS): New macro.
2434 * callproc.c (init_callproc):
2435 * charset.c (init_charset):
2436 * fileio.c (check_existing, check_executable, check_writable)
2438 * lread.c (openp, load_path_check):
2439 * process.c (allocate_pty):
2441 Use effective UID when checking permissions, not real UID.
2442 * callproc.c (init_callproc):
2443 * charset.c (init_charset):
2444 * lread.c (load_path_check, init_lread):
2445 Test whether directories are accessible, not merely whether they exist.
2446 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2447 * fileio.c (check_existing, check_executable, check_writable)
2449 Use symbolic names instead of integers for the flags, as they're
2451 (check_writable): New arg AMODE. All uses changed.
2452 Set errno on failure.
2453 (Ffile_readable_p): Use faccessat, not stat + open + close.
2454 (Ffile_writable_p): No need to call check_existing + check_writable.
2455 Just call check_writable and then look at errno. This saves a syscall.
2456 dir should never be nil; replace an unnecessary runtime check
2457 with an eassert. When checking the parent directory of a nonexistent
2458 file, check that the directory is searchable as well as writable, as
2459 we can't create files in unsearchable directories.
2460 (file_directory_p): New function, which uses 'stat' on most platforms
2461 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2462 (Ffile_directory_p, Fset_file_times): Use it.
2463 (file_accessible_directory_p): New function, which uses a single
2464 syscall for efficiency.
2465 (Ffile_accessible_directory_p): Use it.
2466 * xrdb.c (file_p): Use file_directory_p.
2467 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2468 * lread.c (openp): When opening a file, use fstat rather than
2469 stat, as that avoids a permissions race. When not opening a file,
2470 use file_directory_p rather than stat.
2471 (dir_warning): First arg is now a usage string, not a format.
2472 Use errno. All uses changed.
2473 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2474 that merely introduced a race.
2475 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2476 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2477 and similarly for the other O_* flags.
2478 * w32.c (sys_faccessat): Rename from sys_access and switch to
2479 faccessat's API. All uses changed.
2480 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2481 (magic_db): Rename from magic_file_p.
2482 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2483 char *, so that we don't have to test for file existence
2484 separately from opening the file for reading. This removes a race
2485 fixes a permission-checking problem, and simplifies the code.
2487 (file_p): Remove; no longer needed.
2489 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2491 Omit glyphs initialization at startup.
2492 * dispnew.c (glyphs_initialized_initially_p): Remove.
2493 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2494 (Fredraw_frame): Move actual code from here...
2495 (redraw_frame): ...to here. Add eassert. Adjust comment.
2496 (Fredraw_display): Use redraw_frame.
2497 * xdisp.c (clear_garbaged_frames): Likewise.
2499 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2501 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2502 passed to pint2str and pint2hrstr to be at most the size of the
2503 frame's decode_mode_spec_buffer. This avoids crashes with very
2504 large values of FIELD_WIDTH argument to decode_mode_spec.
2507 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2509 Fix a race with verify-visited-file-modtime (Bug#12863).
2510 Since at least 1991 Emacs has ignored an mtime difference of no
2511 more than one second, but my guess is that this was to work around
2512 file system bugs that were fixed long ago. Since the race is
2513 causing problems now, let's remove that code.
2514 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2515 whose time stamp is off by no more than a second. Insist that the
2516 file time stamps match exactly.
2518 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2520 * frame.h (struct frame): Convert external_tool_bar member to
2521 1-bit unsigned bitfield.
2522 * termhooks.h (struct terminal): Remove mouse_moved member since
2523 all users are long dead. Adjust comment on mouse_position_hook.
2525 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2527 Simplify by using FOR_EACH_FRAME here and there.
2528 * frame.c (next_frame, prev_frame, other_visible_frames)
2529 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2530 * w32term.c (x_window_to_scroll_bar): Likewise.
2531 * window.c (window_list): Likewise.
2532 * xdisp.c (x_consider_frame_title): Likewise.
2533 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2534 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2535 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2536 * xmenu.c (menubar_id_to_frame): Likewise.
2537 * xselect.c (frame_for_x_selection): Likewise.
2538 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2539 (x_window_to_menu_bar): Likewise.
2540 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2542 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2544 * data.c (Qdefalias_fset_function): Now static.
2546 Another tweak to vectorlike_header change.
2547 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2548 Remove, and replace all uses with ...
2549 (next_in_free_list, set_next_in_free_list):
2550 New functions, which respect C's aliasing rules better.
2552 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2554 * window.c (list4i): Rename from 'quad'. All uses changed.
2555 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2557 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2559 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2560 warning about mixing declarations and code in ISO C90.
2562 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2564 * window.c (Fsplit_window_internal): Set combination limit of
2565 new parent window to t iff Vwindow_combination_limit is t;
2566 fixing a regression introduced with the change from 2012-09-22.
2567 (Fset_window_combination_limit): Fix doc-string.
2569 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2571 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2572 amount when the scroll margins are too large. When scrolling
2573 backwards in the buffer, give up if cannot reach point or the
2574 scroll margin within a reasonable number of screen lines.
2575 Fixes point position in window under scroll-up/down-aggressively when
2576 point is positioned many lines beyond the window top/bottom.
2579 * ralloc.c (relinquish): If real_morecore fails to return memory
2580 to the system, don't crash; instead, leave the last heap
2581 unchanged and return. (Bug#12774)
2583 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2585 * lisp.h (AUTOLOADP): New macro.
2586 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2587 * data.c (Ffset): Remove special ad-advice-info handling.
2588 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2590 (Finteractive_form): Simplify.
2591 (Fquo): Don't insist on having at least 2 arguments.
2592 (Qdefalias_fset_function): New var.
2594 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2596 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2598 * nsfont.m (Qcondensed, Qexpanded): New variables.
2599 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2600 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2602 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2604 Fix recently introduced crash on MS-Windows (Bug#12839).
2605 * w32term.h (struct scroll_bar): Use convenient header.
2606 (SCROLL_BAR_VEC_SIZE): Remove.
2607 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2609 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2611 Tweak last vectorlike_header change.
2612 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2613 vectorlike object on the free list. This is introduced to avoid
2614 some (but not all) pointer casting and aliasing problems, see
2615 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2616 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2618 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2620 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2622 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2623 been removed, so remove them here also.
2625 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2627 * doc.c (Fdocumentation): Handle new property
2628 dynamic-docstring-function to replace the old ad-advice-info.
2630 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2632 * fns.c (Qeql, hashtest_eq): Now static.
2634 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2636 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2637 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2638 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2639 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2641 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2643 Use same hash function for hashfn_profiler as for hash_string etc.
2644 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2645 * lisp.h (sxhash_combine): New inline function, with the contents
2646 of the old SXHASH_COMBINE.
2647 * profiler.c (hashfn_profiler): Use it, instead of having a
2648 special hash function containing a comparison that always yields 1.
2650 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2652 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2653 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2654 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2657 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2659 * image.c (xpm_make_color_table_h): Fix compiler error because
2660 make_hash_table changed.
2662 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2664 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2666 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2668 Use ad-hoc comparison function for the profiler's hash-tables.
2669 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2670 (make_log): Use them.
2671 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2672 call Fequal any more.
2673 (Ffunction_equal): New function.
2674 (cmpfn_profiler, hashfn_profiler): New functions.

2681 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2682 (hash_lookup, hash_remove_from_table): Move assertion checking of
2683 hashfn result here. Check hash-equality before calling cmpfn.

2690 * print.c (print_object): Adjust to new hash-table struct.
2691 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2693 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2695 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2696 value of w32-scroll-lock-modifier is neither nil nor one of the
2697 known key modifiers. (Bug#12806)
2699 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2701 Shrink struct vectorlike_header to the only size field.
2702 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2704 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2705 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2706 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2707 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2708 information from the vector header. Adjust comment.
2709 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2710 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2712 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
2713 (struct vectorlike_header): Remove next member. Adjust comment.

2715 (allocate_pseudovector): Adjust prototype.
2716 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
2717 (sweep_string, lisp_malloc): Remove useless prototypes.
2718 (enum mem_type): Adjust comment.
2719 (NEXT_IN_FREE_LIST): New macro.
2720 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2721 (Fmake_bool_vector): Likewise.
2722 (struct large_vector): New type to represent allocation unit for
2723 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2724 (large_vectors): Change type to struct large_vector.
2725 (allocate_vector_from_block): Simplify.
2726 (PSEUDOVECTOR_NBYTES): Replace with...
2727 (vector_nbytes): ...new function. Adjust users.
2728 (sweep_vectors): Adjust processing of large vectors.
2729 (allocate_vectorlike): Likewise.
2730 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2731 Add easserts. Adjust XSETPVECTYPESIZE usage.
2732 (allocate_buffer): Use BUFFER_PVEC_INIT.
2733 (live_vector_p): Adjust to match large vector.
2734 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2735 * buffer.h (struct buffer): Add next member.
2736 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2738 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2739 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2740 (copy_hash_table): Adjust to match vector header change.
2741 * lread.c (defsubr): Use XSETPVECTYPE.
2742 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2743 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2744 (xvecsize): New command.
2746 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2748 * keyboard.c (event_to_kboard): Do not dereference
2749 frame_or_window field of SELECTION_REQUEST_EVENT
2750 and SELECTION_CLEAR_EVENT events (Bug#12814).
2751 * xterm.h (struct selection_input_event): Adjust comment.
2753 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2755 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2756 such as Scroll Lock, if the respective keys are treated as
2757 function keys, not as modifiers. This avoids destroying non-ASCII
2758 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2760 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2762 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2764 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2766 Restore some duplicate definitions (Bug#12814).
2767 This undoes part of the 2012-11-03 changes. Some people build
2768 with plain -g rather than with -g3, and they need the duplicate
2769 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2770 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2771 Define as macros, as well as as enums or as constants.
2773 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2775 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2776 to keypad keys (Bug#12816).
2778 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2780 Minor adjustments of recently-changed frame functions.
2781 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2782 known to be a frame (we're in the FRAMEP branch).
2783 * lisp.h (Qframep): Remove decl. frame.h declares this.
2784 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2785 since they're meant for Lisp fixnum values.
2787 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2789 * window.c (Fwindow_combination_limit): Revert to the only
2790 required argument and adjust docstring as suggested in

2794 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2796 Widely used frame validity and checking functions.
2797 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2798 * frame.c (decode_live_frame, decode_any_frame): New functions.
2799 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2800 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2801 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2802 (Fframe_pointer_visible_p): Use decode_any_frame.
2803 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2804 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2805 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.

2808 (frame_buffer_list, frame_buffer_predicate): Remove.
2809 * lisp.h (frame_buffer_predicate): Remove prototype.
2810 * buffer.c (Fother_buffer): Use decode_any_frame.
2811 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2812 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2813 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2814 (Fclose_font, Ffont_info): Use decode_live_frame.
2815 * fontset.c (check_fontset_name): Likewise.
2816 * terminal.c (Fframe_terminal): Likewise.
2817 * w32fns.c (check_x_frame): Likewise.
2818 * window.c (Fminibuffer_window, Fwindow_at)
2819 (Fcurrent_window_configuration): Likewise.

2838 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2839 (Fwindow_combination_limit): Allow zero number of arguments.
2841 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2843 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2845 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2846 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2847 file descriptor 2 for standard error. (Bug#12805)
2849 2012-11-05 Chong Yidong <cyd@gnu.org>
2851 * process.c (wait_reading_process_output): Revert previous change.
2853 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2855 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2856 This removes code that has been obsolete since around 1990.
2857 * callproc.c (Fcall_process):
2859 * process.c (create_process):
2860 * term.c (dissociate_if_controlling_tty):
2861 Assume setsid exists.
2862 * callproc.c (child_setup): Assume setpgid exists and behaves as
2863 per POSIX.1-1988 or later.
2864 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2865 * emacs.c (shut_down_emacs):
2866 * sysdep.c (sys_suspend, init_foreground_group):
2867 Assume getpgrp behaves as per POSIX.1-1998 or later.
2868 * msdos.c (setpgrp): Remove.
2869 (tcgetpgrp, setpgid, setsid): New functions.
2870 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2871 * term.c (no_controlling_tty): Remove; unused.
2872 * w32proc.c (setpgrp): Remove.
2873 (setsid, tcgetpgrp): New functions.
2875 Simplify by assuming __fpending.
2876 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2877 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2878 Do not assume that __fpending's result fits in int.
2880 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2882 Remove EMACS_OUTQSIZE+sleep hack.
2883 * dispnew.c (update_frame_1): Remove hack for terminals slower
2884 than 2400 bps, which throttled Emacs by having it sleep.
2885 This code hasn't worked since at least 2007, when the multi-tty stuff
2886 was added, and anyway those old terminals are long dead.
2887 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2888 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2890 Fix data-loss with --version (Bug#9574).
2891 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2892 as we can't assume that emacs_strerror is initialized, and strerror
2893 is good enough here.
2894 (main): Invoke atexit earlier, to catch earlier instances of
2895 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2897 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2899 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2900 (keyDown): Remap keypad keys to X11 virtual key codes.
2902 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2904 Fix data-loss with --batch (Bug#9574).
2905 * emacs.c: Include <close-stream.h>.
2906 (close_output_streams): New function.
2907 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2908 and handles errors appropriately.
2909 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2912 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2913 The symptom is a diagnostic "GLib-WARNING **: In call to
2914 g_spawn_sync(), exit status of a child process was requested but
2915 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2916 waitpid(), so exit status can't be returned." The diagnostic
2917 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2918 The real bug is a race condition between Emacs and glib: Emacs
2919 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2920 so that glib can't find it. Work around the bug by invoking
2921 waitpid only on subprocesses that Emacs itself creates.
2922 * process.c (create_process, record_child_status_change):
2923 Don't use special value -1 in pid field, as the caller now must
2924 know the pid rather than having the callee infer it.
2925 The inference was sometimes incorrect anyway, due to another race.
2926 (create_process): Set new 'alive' member if child is created.
2927 (process_status_retrieved): New function.
2928 (record_child_status_change): Use it.
2929 Accept negative 1st argument, which means to wait for the
2930 processes that Emacs already knows about. Move special-case code
2931 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2932 processes that have already been waited for, by testing and
2933 clearing new 'alive' member.
2934 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2935 now does this internally.
2936 (handle_child_signal): Let record_child_status_change do all
2937 the work, since we do not want to reap all exited child processes,
2938 only the child processes that Emacs itself created.
2939 * process.h (Lisp_Process): New boolean member 'alive'.
2941 Omit duplicate definitions no longer needed with gcc -g3.
2942 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2943 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2944 Define only as macros. There's no longer any need to also define
2945 these symbols as enums or as constants, since we now assume
2946 gcc -g3 when debugging.
2948 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2950 * lisp.mk: Adjust comments to the fact that term/internal is now
2951 loaded from loadup.el.
2953 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2954 (msdos_fatal_signal): New function.
2955 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2958 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2959 for GCC versions before 4.
2960 (emacs_raise): Define to call msdos_fatal_signal.
2962 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2963 iterator when starting in the middle of a display or overlay
2966 2012-11-03 Chong Yidong <cyd@gnu.org>
2968 * process.c (wait_reading_process_output): Clean up the last
2971 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2973 * process.c (wait_reading_process_output): Avoid a race condition
2974 with SIGIO delivery (Bug#11536).
2976 2012-11-03 Chong Yidong <cyd@gnu.org>
2978 * buffer.c (cursor_type): Untabify docstring.
2980 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2982 * frame.h (struct frame): Drop can_have_scroll_bars member
2983 which is meaningless for a long time. Adjust comments.
2984 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2985 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2987 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2989 * window.c (decode_next_window_args): Update window arg after
2990 calling decode_live_window and so fix crash reported at
2991 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2992 by Juanma Barranquero <lekktu@gmail.com>.
2993 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2994 * font.c (Ffont_at): Likewise.
2996 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2998 * widget.c (resize_cb): New function.
2999 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3000 (EmacsFrameResize): Check if all is up to date before changing frame
3003 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3005 Implement backtrace output for fatal errors on MS-Windows.
3006 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3007 (BACKTRACE_LIMIT_MAX): New macro.
3008 (w32_backtrace): New function.
3009 (emacs_abort): Use w32_backtrace when the user chooses not to
3010 attach a debugger. Update the text of the abort dialog.
3012 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3014 Window-related stuff cleanup here and there.
3015 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3016 Use decode_any_window.
3017 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3018 * xdisp.c (Fformat_mode_line): Likewise.
3019 * font.c (Ffont_at): Use decode_live_window.
3020 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3021 * window.c (decode_next_window_args): Likewise.
3022 (decode_any_window): Remove static.
3023 * window.h (decode_any_window): Add prototype.
3024 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3025 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3028 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3030 Remove pad from struct input_event.
3031 * termhooks.h (struct input_event): Remove padding field.
3033 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3034 member is never cons for a long time. Adjust comment.
3035 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3036 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3037 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3038 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3040 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3042 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3044 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3046 Fix crash when using Emacs as commit editor for git (Bug#12697).
3047 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3048 and it is configured in conf_post.h.
3049 (Fcall_process): Don't invoke both setsid and setpgid; the former
3050 is enough, if it exists.
3051 * callproc.c (Fcall_process, child_setup):
3052 * process.c (create_process): Use setpgid.
3053 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3055 * dispnew.c (init_display): Initialize the foreground group
3056 if we are running a tty display.
3057 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3058 * lisp.h (init_foreground_group): New decl.
3059 * sysdep.c (inherited_pgroup): New static var.
3060 (init_foreground_group, tcsetpgrp_without_stopping)
3061 (narrow_foreground_group, widen_foreground_group): New functions.
3062 (init_sys_modes): Narrow foreground group.
3063 (reset_sys_modes): Widen foreground group.
3065 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3067 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3069 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3071 * minibuf.c (read_minibuf): Restore current buffer since
3072 choose_minibuf_frame calling Fset_frame_selected_window may
3073 change it (Bug#12766).
3075 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3077 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3079 2012-10-30 Kenichi Handa <handa@gnu.org>
3081 * font.c (Ffont_at): If WINDOW is specified and it is not
3082 displaying the current buffer, signal an error.
3084 2012-10-29 Daniel Colascione <dancol@dancol.org>
3086 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3087 In preparation for fixing bug#12739, move these functions from
3090 * coding.h, coding.c: ... to here, and compile them only when
3091 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3092 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3094 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3096 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3097 (timer_loop, getitimer, setitimer): Use it instead of
3098 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3100 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3103 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3105 * nsterm.m (NO_APPDEFINED_DATA): New define.
3106 (last_appdefined_event_data): New variable
3107 (last_appdefined_event): Remove.
3108 (ns_select): Initialize t from last_appdefined_event_data instead
3109 of [last_appdefined_event data1].
3110 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3111 remove last_appdefined_event (Bug#12698).
3113 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3115 * frame.c (x_set_font): Catch internal error.
3117 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3119 Avoid overflow in w32 implementation of interval timers.
3120 When possible, for ITIMER_PROF count only times the main thread
3122 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3123 'volatile ULONGLONG' types. All the other data which was
3124 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3125 (GetThreadTimes_Proc): New typedef.
3126 (w32_get_timer_time): New function, returns a suitable time value
3128 (timer_loop): Enter critical section when accessing ULONGLONG
3129 values of the itimer_data struct, as these accesses are no longer
3130 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3131 Remove unused variable.
3132 (init_timers): Initialize s_pfn_Get_Thread_Times.
3133 (start_timer_thread): Don't assign itimer->caller_thread here.
3134 (getitimer): Assign itimer->caller_thread here.
3135 (setitimer): Always call getitimer to get the value of ticks_now.
3136 (sys_spawnve): Avoid compiler warning about format mismatch.
3138 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3140 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3141 mouse movement events if the menu bar is active. This avoids
3142 producing a busy "hour-glass" cursor by Windows if the mouse
3143 pointer is positioned over a tooltip shown for some menu item.
3145 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3147 Don't assume process IDs fit in int.
3148 * emacs.c (shut_down_emacs) [!DOS_NT]:
3149 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3150 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3151 Use pid_t, not int, to store process IDs, as 'int'
3152 is not wide enough on a few platforms (e.g., AIX and IRIX).
3154 2012-10-23 Kenichi Handa <handa@gnu.org>
3156 The following change is to make face-font-rescale-alist work
3157 correctly for non-ASCII fonts.
3159 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3160 (font_open_for_lface): Handle Vface_font_rescale_alist.
3162 2012-10-23 Chong Yidong <cyd@gnu.org>
3164 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3166 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3168 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3170 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3172 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3175 2012-10-21 Glenn Morris <rgm@gnu.org>
3177 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3179 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3181 Port to OpenBSD 5.1.
3182 * frame.c (Fmouse_position, Fmouse_pixel_position):
3183 * xdisp.c (produce_stretch_glyph):
3184 Declare local vars only when they're needed.
3185 This is clearer and avoids a warning on OpenBSD about unused vars.
3186 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3187 This is safer, and avoids OpenBSD warnings about unused vars.
3188 * keyboard.c (record_menu_key): Remove unnecessary decl.
3189 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3190 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3191 as our definition clashes with OpenBSD's.
3192 * xfaces.c (load_face_colors, check_lface_attrs)
3193 (get_lface_attributes_no_remap, get_lface_attributes)
3194 (lface_fully_specified_p, x_supports_face_attributes_p)
3195 (tty_supports_face_attributes_p, face_fontset, realize_face)
3196 (realize_x_face, realize_tty_face):
3197 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3198 merely Lisp_Object *. This is more informative and avoids
3199 a warning on OpenBSD about accessing beyond an object's size.
3201 2012-10-20 Chong Yidong <cyd@gnu.org>
3203 * lread.c (Fload): Doc fix (Bug#12592).
3205 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3207 * font.c (Ffont_at): Fix previous change.
3209 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3211 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3212 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3215 * alloc.c (NSTATICS): Decrease to 0x800.
3217 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
3219 * fns.c (Fnreverse): Include the problem element when signaling an
3222 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
3224 * nsterm.m (ns_select): Check writefds before call to
3225 FD_ISSET (Bug#12668).
3227 2012-10-18 Daniel Colascione <dancol@dancol.org>
3229 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3230 (staticpro): If we run out of staticpro slots, die with an
3231 informative error instead of just calling emacs_abort.
3233 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3235 Fix two flaws reported by Dmitry Antipov.
3236 * window.c (Ftemp_output_buffer_show): Remove.
3237 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
3238 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
3240 2012-10-17 Eli Zaretskii <eliz@gnu.org>
3242 * makefile.w32-in ($(BLD)/w32.$(O)):

3490 since unsigned is guaranteed to have that behavior and signed is not.
3491 (read_char): Use ptrdiff_t for string length.
3492 (get_input_pending): Remove first argument, since it was always
3493 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3494 and behave as if it had that value. Return new value of
3495 input_pending. All callers changed.
3496 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3497 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3526 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3528 * commands.h (immediate_quit): Remove duplicate decl.

3540 match what GetLastError returns. Explain why the function is
3543 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3544 'is_tooltip_frame', to avoid confusion with its global namesake.
3546 2012-10-08 Daniel Colascione <dancol@dancol.org>
3548 * xdisp.c (start_hourglass): Call w32_note_current_window when
3549 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3550 build that caused Emacs to display the hourglass cursor forever.
3552 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3553 which is broken under remote desktop, calculate the number of
3554 colors available for a display based on the display's number of
3555 planes and number of bits per pixel per plane. (bug#10397).
3557 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3559 * nsfont.m (Vfonts_in_cache): New variable.
3560 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3561 are used. Add cached fonts to Vfonts_in_cache.
3562 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3564 2012-10-08 Juanma Barranquero <lekktu@gmail.com>

3592 2012-10-08 Daniel Colascione <dancol@dancol.org>
3594 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3595 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3596 accidental message numbering hole. Change other messages to

3616 * w32fns.c: Include w32common.h; include w32heap.h only in
3619 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3620 Use `report_file_error' instead of `error' in order to better
3621 inform users of what went wrong. Increase NTGUI_UNICODE file
3622 dialog box file name length to 32k, the maximum allowed by the NT
3625 * w32common.h: New file.
3626 (ROUND_UP, ROUND_DOWN, get_page_size)

3630 (OS_NT, os_subtype, cache_system_info): Move here.
3632 * unexw32.c, unexcw.c: Include w32common.h.
3634 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3635 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3636 to call syms_of_w32select.
3638 * cygw32.h: Remove obsolete EXFUN declarations.
3640 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3652 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3654 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3657 2012-10-08 Daniel Colascione <dancol@dancol.org>
3659 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3660 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3661 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

3664 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3665 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3666 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3667 now a supported configuration.
3669 * Makefile.in: consolidate image variables into LIBIMAGE; add
3670 W32_OBJ and W32_LIBS. Compile new files.
3673 (_DebPrint) declare tracing facility for W32 debugging. We need
3674 to unify tracing later.
3676 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3677 unconditional use of W32 Unicode functions. Cygwin runs only on
3678 100% Unicode operating systems.
3680 * cygw32.c: New file. Define Cygwin-specific facilities.
3681 (Fcygwin_convert_path_to_windows)
3682 (Fcygwin_convert_path_from_windows): New user functions for
3683 accessing Cygwin path-munging routines.
3685 * cygw32.h: New file.
3686 (WCSDATA, to_unicode, from_unicode): Define facilities for storing

3690 (w32_strerror): Just what it says on the tin.
3692 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3693 also run for Cygwin; both systems have the same problem with using
3694 GUI facilities in a forked child. Also call syms_of_cygw32,
3695 syms_of_w32select in correct places.
3697 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3698 needs fork-then-exec for daemon launching.
3700 * font.h: Include frame.h.
3702 * image.c: Use the image library cache machinery only when we're
3703 compiling for native WINDOWSNT; Cygwin can use shared libraries
3704 like any other Unixlike system.
3706 * keyboard.c: Clarify a comment regarding the input loop.
3708 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3709 functions directly instead of trying to detect at runtime that our
3710 host operating system supports them. We make this change for two
3711 reasons: Cygwin lacks support for the multibyte character
3712 conversion functions used by the legacy menu code, and Cygwin
3713 never needs to rely on non-Unicode APIs.
3715 * unexw32.c (hinst): Declare extern.
3717 * w32.c: Change header order;
3718 (w32_strerror): Move to w32fns.c because we need it for
3719 non-WINDOWSNT builds.
3721 * w32.h: Add #error macro to make sure we don't include w32.h for
3722 Cygwin builds. Remove w32select declarations.
3724 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3725 w32fns.c. w32console.c is WINDOWSNT-only.
3727 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3728 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3730 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3731 (w32_major_version, w32_minor_version, w32_build_number)
3732 (os_subtype, sound_type): Define here
3733 (w32_defined_color): Make color parameter const for consistency
3734 with other _defined_color functions.
3735 (w32_createwindow): Unconditionally call w32_init_class instead of
3736 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3737 through the code is complex and unnecessary because class
3738 registration is practically free.
3739 (w32_name_of_message): New EMACSDEBUG-only function.
3740 (Fset_message_beep): Move here
3741 (Fx_open_connection): Require that the display name for Windows be
3742 "w32" for consistency, emacsclient disambiguation, and maybe, one
3743 day, multi-window-system support.
3744 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3745 Cygwin files for W32 GUI facilities, since these clearly don't
3746 expect Cygwin names.
3747 (_DebPrint): Define.
3748 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3749 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3750 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3751 (w32_last_error): Remove.
3753 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3755 * w32heap.c (syspage_mask): Declare here.
3756 (cache_system_info): Remove.
3758 * w32inevt.c (faked_key): Define globally, not statically.
3759 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3760 (w32_console_toggle_lock_key): Move to w32fns.c.
3762 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3764 * w32proc.c (_DebPrint): Move to w32fns.c.
3765 * w32select.c: Include string.h, stdio.h for Cygwin.
3766 * w32select.h: New File.
3768 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3770 (w32_message_fd): New variable. Under Cygwin, holds the file
3771 descriptor the system used to tell us about pending thread
3774 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3775 that prevented compilation under non-WINDOWSNT systems.
3777 (w32_initialize): Open /dev/windows and assign it to
3778 w32_message_fd. Provide w32 feature.
3780 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3781 (WM_EMACS_INPUT_READY): add.
3782 (prepend_msg, w32_message_fd): Declare globally.
3785 (keyboard_handle): Use only when WINDOWSNT.
3786 (notify_msg_ready): New function. Posts a message to the main
3787 thread's message queue under CYGWIN, which wakes up the main
3788 thread from select(2) by making the /dev/windows file descriptor
3789 ready. Under WINDOWSNT, it sets an event the same way the old
3792 (post, prepend_msg): Actually call notify_msg_ready instead of
3793 setting the input event directly.
3795 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3797 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3798 but it still has blocs in it, don't return it to the system,
3799 instead of aborting. (Bug#12402)
3801 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3803 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3805 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3806 MAC_OS_X_VERSION_10_6.
3807 (syms_of_nsterm): Remove comment about Panther and above for
3809 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

3811 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3813 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3814 MAC_OS_X_VERSION_10_4.
3816 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3817 MAC_OS_X_VERSION_10_2.
3819 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3821 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3822 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3824 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3825 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3826 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3827 Remove ns_in_resize check.
3828 (ns_clear_frame_area): Remove resize handle code.
3830 * nsfns.m (ns_in_resize): Remove.
3831 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3832 Remove ns_in_resize check.
3834 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3836 Improve sys_siglist detection.
3837 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3838 defined as a macro, as is done in Solaris.
3839 (sys_siglist_entries): New macro.
3840 (save_strsignal): Use it.
3841 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3842 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3844 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3846 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3847 fullscreen/Fullscreen.
3849 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3850 tobar_height is new.
3852 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3853 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3854 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3855 (windowDidResize:): Check for correct window if old style fullscreen.
3856 Capitalize word in comment. Remove incorrect comment.
3857 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3858 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3859 error in drawing background.
3860 (toggleFullScreen:): Remove comment. Rearrange calls.
3861 Set toolbar values to zero, save old height in tobar_height.
3862 Restore tool bar height when leaving fullscreen.
3863 (canBecomeMainWindow): New function.
3865 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3867 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3869 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3871 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3873 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3874 that time stamps of directories could also be changed.
3875 Don't request the too broad GENERIC_WRITE, only the more restrictive
3876 FILE_WRITE_ATTRIBUTES access rights.
3878 * fileio.c (Fset_file_times): Special-case ignoring errors for
3879 directories only on MSDOS, not on MS-Windows.
3881 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3883 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3885 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3887 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3888 see whether CreateFile failed.
3890 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3892 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3893 to avoid similar races.
3894 * keyboard.c (pending_signals): Now bool, not int.
3896 Port timers to OpenBSD, plus check for timer failures.
3897 OpenBSD problem reported by Han Boetes.
3898 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3900 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3901 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3902 like OpenBSD, which has timer_settime but does not declare it.
3903 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3904 whether to use itimerspec-related primitives. All uses of
3905 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3907 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3909 * profiler.c (handle_profiler_signal): Fix a malloc race
3910 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3912 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3914 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3916 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3918 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3919 consistent with the change in return value of 'safe_strsignal'.
3921 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3923 Prefer plain 'static' to 'static inline' (Bug#12541).
3924 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3925 (bidi_set_sor_type, bidi_push_embedding_level)
3926 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3927 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3931 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3932 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3933 Now 'static', not 'static inline'.
3935 Count overruns when profiling; change units to ns.
3936 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3937 Give extra weight to samples after overruns, to attempt to count
3938 the time more accurately.
3939 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3940 the underlying primitives nominally do ns.
3941 (Fprofiler_cpu_start): Document the change. Mention that
3942 the sampling intervals are only approximate.
3944 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3946 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3948 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3949 case for the special 0 coding-system.
3951 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3952 (Fmake_overlay): Remove redundant tests.
3953 (fix_start_end_in_overlays): Remove redundant recentering.
3955 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3957 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3958 Update dependencies.
3960 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3962 Fix a malloc race condition involving strsignal.
3963 A signal can arrive in the middle of a malloc, and Emacs's signal
3964 handler can invoke strsignal, which can invoke malloc, which is
3965 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3966 Fix it by altering the signal handler so that it does not invoke
3968 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3969 * process.c (status_message): Use const pointer, in case strsignal
3970 is #defined to safe_strsignal.
3971 * sysdep.c (sys_siglist, init_signals): Always define and
3972 initialize a substitute sys_siglist if the system does not define
3973 one, even if HAVE_STRSIGNAL.
3974 (safe_strsignal): Rename from strsignal. Always define,
3975 using sys_siglist. Return a const pointer.
3976 * syssignal.h (safe_strsignal): New decl.
3977 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3979 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3981 * w32proc.c (timer_loop): Fix code that waits for timer
3982 expiration, to avoid high CPU usage.
3984 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3986 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3987 (sweep_weak_table): Remove redundant prototypes.
3989 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3991 * emacs.c: Move the inclusion of TERM_HEADER after including
3992 windows.h on WINDOWSNT. This avoids compilation problems with
3995 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3997 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3998 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3999 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4000 as the previous version used 'void *'.
4002 * ralloc.c (ROUNDUP): Fix last change.
4003 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4006 * w32proc.c <disable_itimers>: New static flag.
4007 (init_timers): Initialize it to zero, after creating the critical
4008 sections used by the timer threads.
4009 (term_timers): Set to 1 before deleting the critical sections.
4010 (getitimer, setitimer): If disable_itimers is non-zero, return an
4011 error indication without doing anything. Reported by Fabrice
4012 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4013 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4015 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4018 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4019 term_ntproc after all the other bookkeeping, to get timers working
4020 as long as possible.
4022 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4024 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4025 Suggested by Juri Linkov in
4026 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4028 Prefer plain 'static' to 'static inline' (Bug#12541).
4029 With static functions, modern compilers inline pretty well by
4030 themselves; advice from programmers often hurts as much as it helps.
4031 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4032 this change shrinks the text size of the Emacs executable by 1.1%
4033 without affecting CPU significantly in my benchmark.
4034 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4035 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4109 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
4110 Now 'static', not 'static inline'.
4113 (bidi_copy_it): Do the whole copy with a single memcpy.
4114 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4116 Revert the FOLLOW-SYMLINKS change for file-attributes.
4117 Doing it right would require several changes to Tramp, and there's
4118 not enough time to get that tested before the freeze today.
4119 * dired.c (directory_files_internal, Ffile_attributes):
4122 * frame.c (x_report_frame_params): Port better to wider ints.
4123 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4124 or that pointers can be printed in 15 decimal digits.
4125 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4306 Suggested by Eli Zaretskii in
4307 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
4309 2012-09-30 Eli Zaretskii <eliz@gnu.org>
4311 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
4312 HAVE_TIMER_SETTIME is defined.

4316 Profiler improvements: more-accurate timers, overflow checks.
4317 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4318 signal.h, setjmp.h. Include systime.h instead.
4319 (saturated_add): New function.

4326 All uses changed to store the new value.
4327 (handle_profiler_signal): Rename from sigprof_handler_1,
4328 for consistency with other handlers. Do not check whether
4329 cpu_log is a hash-table if garbage collecting, since it
4330 doesn't matter in that case.

4332 for consistency with other handlers.
4333 (setup_cpu_timer): New function, with much of what used to be in
4334 Fprofiler_cpu_start. Check for out-of-range argument.
4335 Prefer timer_settime if available, and prefer
4336 thread cputime clocks, then process cputime clocks, then
4337 monotonic clocks, to the old realtime clock. Use make_timeval
4338 to round more-correctly when falling back to setitimer.
4339 (Fprofiler_cpu_start): Use it.
4340 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4341 Don't assume that passing NULL as the 2nd argument of setitimer

4344 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4345 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4346 non-fatal signal handlers. Ignore SIGPROF on startup.
4347 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4348 in profiler.c, since sysdep.c now uses it.
4350 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4406 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4407 Since this stuff is now private to charset.c, there's no need for
4408 a public macro and no need to inline by hand.

4482 (sys_kill): Improve commentary.
4484 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4485 consistency with a signature of a signal handler. All callers
4487 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4488 install term_ntproc as a signal handler for SIGABRT, as that
4489 should be done by the dumped Emacs.

4610 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4612 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4613 fatal_error_backtrace.
4615 * w32proc.c (sys_kill): Undo last change: don't do anything when
4616 invoked to deliver SIGABRT to our own process. This is now
4617 handled by emacs_raise.
4619 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4621 * w32term.c (w32_read_socket): Remove leftover reference to
4622 interrupt_input_pending.
4624 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4626 Do not use SA_NODEFER.
4627 Problem reported by Dani Moncayo in
4628 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4630 * sysdep.c (emacs_abort): Do not reset signal handler.
4631 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4632 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4633 wanted even on POSIXish hosts, and it doesn't work on Windows.
4635 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4637 * xterm.c (x_term_init): Call fixup_locale before and after calling
4638 gtk_init (Bug#12392).
4640 2012-09-23 Chong Yidong <cyd@gnu.org>
4642 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4643 Vdynamic_library_alist.
4645 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4646 (Fgnutls_available_p): Caller changed.
4648 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4649 (Flibxml_parse_xml_region): Likewise.
4651 * dispextern.h (struct image_type): Remove arg from init function.
4653 * image.c (Finit_image_library, lookup_image_type)
4654 (define_image_type): Remove now-unneeded second arg.
4655 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4656 (init_tiff_functions, init_gif_functions, init_svg_functions):
4657 Arglist and w32_delayed_load calling convention changed.
4658 (gs_type): Remove init_gs_functions; there is no such function.
4659 (valid_image_p, make_image): Fix caller to lookup_image_type.
4661 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4663 Simplify and avoid signal-handling races (Bug#12471).
4665 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4666 Avoid recursive loop if there's a fatal error in the function itself.
4667 * atimer.c (pending_atimers):
4668 * blockinput.h: Don't include "atimer.h"; no longer needed.
4669 (interrupt_input_pending): Remove. All uses removed.
4670 pending_signals now counts both atimers and ordinary interrupts.
4671 This is less racy than having three separate pending-signal flags.
4672 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4674 Rename from their upper-case counterparts BLOCK_INPUT,
4675 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4676 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4677 This makes it easier to access volatile variables more accurately.
4678 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4679 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4680 that's more reliable if the code is buggy and sets
4681 interrupt_input_blocked to a negative value. All uses changed.
4682 * atimer.c (deliver_alarm_signal):
4683 Remove. No need to deliver this to the parent; any thread can
4684 handle this signal now. All uses replaced by underlying handler.
4685 * atimer.c (turn_on_atimers):
4686 * dispnew.c (handle_window_change_signal):
4687 * emacs.c (handle_danger_signal):
4688 * keyboard.c (kbd_buffer_get_event):
4689 Don't reestablish signal handler; not needed with sigaction.
4690 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4692 Rework to avoid unnecessary accesses to volatile variables.
4693 (UNBLOCK_INPUT_TO): Now a function.
4694 (totally_unblock_input, unblock_input): New decls.
4695 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4696 (init_data): Remove. Necessary stuff now done in init_signal.
4697 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4698 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4699 (fatal_error_code): Remove; no longer needed.
4700 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4701 it doesn't always backtrace. All uses changed. No need to reset
4702 signal to default, since sigaction and/or die does that for us now.
4703 Use emacs_raise (FOO), not kill (getpid (), FOO).
4704 (main): Check more-accurately whether we're dumping.
4705 Move fatal-error setup to sysdep.c
4706 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4707 * gtkutil.c (xg_get_file_name, xg_get_font):
4708 Remove no-longer-needed signal-mask manipulation.
4709 * keyboard.c, process.c (POLL_FOR_INPUT):
4710 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4711 * keyboard.c (read_avail_input): Remove.
4712 All uses replaced by gobble_input.
4713 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4714 (kbd_buffer_store_event_hold, gobble_input):
4715 (record_asynch_buffer_change) [USABLE_SIGIO]:
4716 (store_user_signal_events):
4717 No need to mess with signal mask.
4718 (gobble_input): If blocking input and there are terminals, simply
4719 set pending_signals to 1 and return. All hooks changed to not
4720 worry about whether input is blocked.
4721 (process_pending_signals): Clear pending_signals before processing
4722 them, in case a signal comes in while we're processing.
4723 By convention callers now test pending_signals before calling us.
4724 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4725 New functions, to support changes to blockinput.h.
4726 (handle_input_available_signal): Now extern.
4727 (reinvoke_input_signal): Remove. All uses replaced by
4729 (quit_count): Now volatile, since a signal handler uses it.
4730 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4731 All callers changed. Block SIGINT only if not already blocked.
4732 Clear sigmask reliably, even if Fsignal returns, which it can.
4733 Omit unnecessary accesses to volatile var.
4734 (quit_throw_to_read_char): No need to restore sigmask.
4735 * keyboard.c (gobble_input, handle_user_signal):
4736 * process.c (wait_reading_process_output):
4737 Call signal-handling code rather than killing ourselves.
4738 * lisp.h: Include <float.h>, for...
4739 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4740 (pending_signals): Now volatile.
4741 (syms_of_data): Now const if IEEE floating point.
4742 (handle_input_available_signal) [USABLE_SIGIO]:
4743 (terminate_due_to_signal, record_child_status_change): New decls.
4744 * process.c (create_process): Avoid disaster if memory is exhausted
4745 while we're processing a vfork, by tightening the critical section
4747 (send_process_frame, process_sent_to, handle_pipe_signal)
4748 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4750 (send_process): No need for setjmp/longjmp any more, since the
4751 SIGPIPE stuff is now gone. Instead, report an error if errno
4753 (record_child_status_change): Now extern. PID and W are now args.
4754 Return void, not bool. All callers changed.
4755 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4756 Remove. All uses removed. This bug should be fixed now in a
4758 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4759 and record the child status change directly. This avoids the
4760 need to futz with the signal mask.
4761 (process_fatal_action): Move here from emacs.c.
4762 (emacs_sigaction_flags): New function, containing
4763 much of what used to be in emacs_sigaction_init.
4764 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4765 caught by emacs, to make races less likely.
4766 (deliver_process_signal): Rename from handle_on_main_thread.
4768 (BACKTRACE_LIMIT_MAX): Now at top level.
4769 (thread_backtrace_buffer, threadback_backtrace_pointers):
4771 (deliver_thread_signal, deliver_fatal_thread_signal):
4772 New functions, for more-accurate delivery of thread-specific signals.
4773 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4774 (deliver_arith_signal): Handle in this thread, not
4775 in the main thread, since it's triggered by this thread.
4776 (maybe_fatal_sig): New function.
4777 (init_signals): New arg DUMPING so that we can be more accurate
4778 about whether we're dumping. Caller changed.
4779 Treat thread-specific signals differently from process-general signals.
4780 Block all signals while handling fatal error; that's safer.
4781 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4783 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4784 Ignore SIGPIPE unless batch.
4785 (emacs_backtrace): Output backtrace for the appropriate thread,
4786 which is not necessarily the main thread.
4787 * syssignal.h: Include <stdbool.h>.
4788 (emacs_raise): New macro.
4789 * xterm.c (x_connection_signal): Remove; no longer needed
4790 now that we use sigaction.
4791 (x_connection_closed): No need to mess with sigmask now.
4792 (x_initialize): No need to reset SIGPIPE handler here, since
4793 init_signals does this for us now.
4795 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4797 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4798 background rect may be larger (Bug#12245).
4800 2012-09-23 Chong Yidong <cyd@gnu.org>
4802 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4804 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4806 * .gdbinit: Just stop at fatal_error_backtrace.
4807 See Stefan Monnier's request in
4808 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4809 Remove no-longer-used query of system type.
4811 2012-09-22 Chong Yidong <cyd@gnu.org>
4813 * search.c (Freplace_match): Doc fix (Bug#12325).
4815 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4817 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4818 (Fline_end_position): Doc fix.
4820 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4822 2012-09-22 Chong Yidong <cyd@gnu.org>
4824 * dispextern.h (struct image_type): Add new slot, storing a type
4825 initialization function.
4827 * image.c (define_image_type): Call the image initializer function
4828 if it is defined. Arguments and return value changed.
4829 (valid_image_p, make_image): Callers changed.
4830 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4831 (gif_type, imagemagick_type, svg_type, gs_type):
4832 Add initialization functions.
4833 (Finit_image_library): Call lookup_image_type.
4834 (CHECK_LIB_AVAILABLE): Macro deleted.
4835 (lookup_image_type): Call define_image_type here, rather than via
4836 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4837 (syms_of_image): Move define_image_type calls for xbm_type and
4838 pbm_type to lookup_image_type.
4840 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4842 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4843 'idle_timers' from here ...
4844 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4845 lists, to avoid infloops when the timer does something stupid,
4846 like reinvoke itself with the same or smaller time-out.
4849 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4851 * window.c (Fsplit_window_internal): Handle only Qt value of
4852 Vwindow_combination_limit separately.
4853 (Qtemp_buffer_resize): New symbol.
4854 (Vwindow_combination_limit): New default value.
4857 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4859 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4860 the new overlay string. (Bug#10159)
4862 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4864 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4865 or that fprintf is async-signal-safe. POSIX doesn't require
4868 2012-09-22 Chong Yidong <cyd@gnu.org>
4870 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4873 2012-09-22 Kenichi Handa <handa@gnu.org>
4875 * composite.c (composition_reseat_it): Handle the case that a
4876 grapheme cluster is not covered by a single font (Bug#12352).
4878 2012-09-21 Chong Yidong <cyd@gnu.org>
4880 * image.c (define_image_type): Avoid adding duplicate types to
4881 image_types (Bug#12463). Suggested by Jörg Walter.
4883 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4885 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4886 (print_load_command_name): Add case LC_DATA_IN_CODE.
4887 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4889 2012-09-21 Glenn Morris <rgm@gnu.org>
4891 * eval.c (Frun_hook_with_args_until_success)
4892 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4894 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4896 * fileio.c (Ffile_selinux_context): Only call freecon when
4897 lgetfilecon succeeded.
4898 (Fset_file_selinux_context): Likewise. (Bug#12444)
4900 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4902 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4903 reordering, locate the cursor by calling set_cursor_from_row; if
4904 that fails, clear the desired glyph matrix before returning a
4905 failure indication to the caller. Fixes leaving garbled display
4906 when fast scrolling with a down-key. (Bug#12403)
4907 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4908 scrolling through multibyte text.
4910 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4912 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4913 calling mark_vectorlike since that's the one that marks the window.
4914 (mark_discard_killed_buffers): Mark the final cdr.
4915 * window.h (struct window): Move prev/next_buffers to the
4916 non-standard fields.
4917 * window.c (make_window): Initialize prev/next_buffers manually.
4919 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4921 Omit unused arg EXPECTED from socket hooks.
4922 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4923 * nsterm.m (ns_term_init):
4924 * termhooks.h (struct terminal.read_socket_hook):
4925 * w32inevt.c (w32_console_read_socket):
4926 * w32term.c (w32_read_socket):
4927 * xterm.c (XTread_socket):
4928 Omit unused arg EXPECTED. All callers changed.
4929 (store_user_signal_events): Return void, not int, since callers no
4930 longer care about the return value. All uses changed.
4932 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4934 * w32gui.h (XParseGeometry): Do not declare.
4936 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4938 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4939 Ignore 'expected'. See Eli Zaretskii in
4940 <http://bugs.gnu.org/12471#8> (last line).
4942 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4943 (XParseGeometry): Now static. Substitute extremal values for
4944 values that are out of range.
4946 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4948 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4950 * nsfns.m (XParseGeometry): Remove.
4951 (Fx_create_frame): Call x_set_offset to correctly interpret
4952 top_pos in geometry.
4954 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4955 (Fx_parse_geometry): If there is a space in string, call
4956 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4958 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4960 * search.c (scan_buffer): Use character positions in calls to
4961 region_cache_forward and region_cache_backward, not byte
4962 positions. (Bug#12196)
4964 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4965 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4967 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4968 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4969 emacs_blocked_malloc, now deleted.
4971 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4973 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4974 The workaround was for improving performance on Solaris 2.4, but
4975 is getting in the way now. Emacs will still work if someone is
4976 still running Solaris 2.4 in a museum somewhere; Sun dropped
4977 support for Solaris 2.4 in 2003.
4978 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4979 * process.c (create_process) [HAVE_WORKING_VFORK]:
4980 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4981 since Emacs no longer uses vfork on that platform.
4983 2012-09-17 Glenn Morris <rgm@gnu.org>
4985 * emacs.c: Use COPYRIGHT.
4987 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4989 Remove configure's --without-sync-input option (Bug#12450).
4990 When auditing signal-handling in preparation for cleaning it up,
4991 I found that SYNC_INPUT has race conditions and would be a real
4992 pain to fix. Since it's an undocumented and deprecated
4993 configure-time option, now seems like a good time to remove it.
4994 Also see <http://bugs.gnu.org/11080#16>.
4995 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4996 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4997 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4998 (malloc_hysteresis):
4999 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5000 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5001 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5002 (dont_register_blocks, bytes_used_when_reconsidered)
5003 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5004 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5005 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5006 Remove. All uses removed.
5007 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5008 implementation, one that depends on whether the new macro
5009 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5011 * atimer.c (run_timers, handle_alarm_signal):
5012 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5013 (handle_async_input, process_pending_signals)
5014 (handle_input_available_signal, init_keyboard):
5015 * nsterm.m (ns_read_socket):
5016 * process.c (wait_reading_process_output):
5017 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5018 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5020 * xterm.c (XTread_socket):
5022 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5023 * eval.c (handling_signal): Remove. All uses removed.
5024 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5025 All uses replaced with the SYNC_INPUT version.
5026 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5028 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5031 * font.c (Ffont_shape_gstring): Remove unused local.
5033 2012-09-16 Glenn Morris <rgm@gnu.org>
5035 * Makefile.in (clean): No longer run nextstep's clean.
5037 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5039 (ns-app): Move here from ns.mk, and simplify.
5040 (clean): Simplify nextstep entry.
5041 * ns.mk: Remove file.
5043 2012-09-17 Kenichi Handa <handa@gnu.org>
5045 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5046 not covert the last few charactes.
5048 2012-09-16 Kenichi Handa <handa@gnu.org>
5050 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5051 here, but just check the validity of glyphs in the glyph-string.
5053 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5055 * window.c (Fwindow_parameter, Fset_window_parameter):
5056 Accept any window as argument (Bug#12452).
5058 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5060 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5061 to ns_term_init to avoid memory leak.
5063 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5064 explicit retain/release.
5065 (ns_term_init): Only allow one display. Initialize outerpool and
5068 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5070 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5071 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5072 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5073 the Microsoft problem in a different way, by altering ../nt/config.nt.
5075 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5090 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5091 by lisp.h. This completes removal of setjmp.h inclusion
5092 erroneously announced in the previous commit. (Bug#12446)
5094 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5097 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5098 not defined as a macro. The latter happens on MS-Windows.
5101 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5103 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5104 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5105 Some instances of '#include <setjmp.h>' removed, if the
5106 only reason for the instance was because "lisp.h" was included.
5107 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5108 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5109 and _longjmp with the new symbols. Emacs already uses _setjmp if
5110 available, so this change affects only POSIXish hosts that have
5111 sigsetjmp but not _setjmp, such as some versions of Solaris and
5112 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5113 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5114 (png_load_body) [HAVE_PNG]:
5115 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5116 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5117 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5118 since PNG requires jmp_buf. This is the only exception to the
5119 general rule that we now use sys_setjmp and sys_longjmp.
5120 This exception is OK since this code does not change the signal
5121 mask or longjmp out of a signal handler.
5123 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5125 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5126 Include "syssignal.h", for 'main_thread'.
5128 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5130 Avoid out-of-range marker position (Bug#12426).
5131 * insdel.c (replace_range, replace_range_2):
5132 Adjust markers before overlays, as suggested by comments.
5133 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5134 Remove redundant check before calling offset_intervals.
5136 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5138 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5139 current buffer (Bug#12387).
5141 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5143 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5145 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5147 Use a more backwards-compatible timer format (Bug#12430).
5148 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5149 vector element, not from the 4th, since PSECS is now at the end.
5150 (Fcurrent_idle_time): Doc fix.
5152 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5154 Function to mark objects and remove killed buffers at once.
5155 * alloc.c (discard_killed_buffers): Rename to ...
5156 (mark_discard_killed buffers) ... new name. Add marking
5157 of remaining objects. Fix comment. Adjust users.
5158 (mark_object): Do not touch frame buffer lists here.
5159 * frame.c (delete_frame): Reset frame buffer lists here.
5161 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5163 Better workaround for GNOME bug when --enable-gcc-warnings.
5164 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5165 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5166 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5168 Simplify SIGIO usage (Bug#12408).
5169 The code that dealt with SIGIO was crufty and confusing, e.g., it
5170 played tricks like "#undef SIGIO" but these tricks were not used
5171 consistently. Simplify mostly by not #undeffing standard symbols,
5172 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5173 or not as we please) rather than "defined SIGIO" (standard symbol
5174 that we probably shouldn't #undef).
5175 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5176 Modules that need it can include it.
5177 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5178 * dispextern.h (ignore_sigio): New decl.
5179 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5180 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5181 * emacs.c (shut_down_emacs):
5182 * keyboard.c (kbd_buffer_store_event_hold):
5183 Use ignore_sigio rather than invoking 'signal' directly.
5184 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5186 (FIONREAD, SIGIO): Do not #undef.
5187 (tty_read_avail_input): Use #error rather than a syntax error.
5188 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5189 for I_PIPE, used by SETUP_SLAVE_PTY.
5190 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5191 * sysdep.c (croak): Remove; no longer needed. This bit of
5192 temporary code, with Fred N. Fish's comment that it's temporary,
5193 has been in Emacs since at least 1992!
5194 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5195 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5196 * syssignal.h (croak): Remove decl.
5197 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5198 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5199 now that we're termios-only.
5200 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5201 * term.c (dissociate_if_controlling_tty): Use #error rather than
5204 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5205 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5206 to work around GNOME bug 683906.
5207 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5208 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5209 This works around GCC bug 54561.
5211 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5213 More fixes for 'volatile' and setjmp/longjmp.
5214 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5215 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5216 (png_load_body) [HAVE_PNG]:
5217 (jpeg_load_body) [HAVE_JPEG]:
5218 New function, with most of the old parent function's body.
5219 (png_load) [HAVE_PNG]:
5220 (jpeg_load) [HAVE_JPEG]:
5221 Invoke the new function, to avoid longjmp munging our locals.
5222 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5223 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5224 longjmp is passed 2, as the C standard doesn't guarantee this.
5225 Instead, store the failure code into mgr->failure_code.
5227 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5229 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5230 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5231 (syms_of_keyboard): Remove support for unread-command-char.
5233 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5235 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5236 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5237 violation. (Bug#12426)
5239 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5241 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5243 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5245 * eval.c: Add `inhibit-debugger'.
5246 (Qinhibit_debugger): New symbol.
5247 (call_debugger): Bind it instead of Qdebug_on_error.
5248 (maybe_call_debugger): Test Vinhibit_debugger.
5249 (syms_of_eval): Define inhibit-debugger.
5250 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5251 (syms_of_xdisp): Remove inhibit-debug-on-message.
5253 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5255 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5256 If a nonvolatile local variable is written before a _longjmp to
5257 the frame containing the variable, and is read after the _longjmp,
5258 the value read is indeterminate. Some local variables of type
5259 'struct handler' and 'struct catchtag' are used in this way, so
5260 mark each of their slots as volatile if the slot can be set before
5261 _longjmp and read afterwards.
5262 * lisp.h (struct handler): var and chosen_clause are now volatile.
5263 (struct catchtag): val, next, and pdlcount are now volatile.
5265 * bidi.c (bidi_push_it, bidi_pop_it):
5266 * fns.c (copy_hash_table):
5267 * image.c (define_image_type):
5268 * keyboard.c (kbd_buffer_store_event_hold):
5269 * process.c (Fprocess_send_eof):
5270 * xfaces.c (x_create_gc) [HAVE_NS]:
5271 * xgselect.c (xg_select):
5272 Prefer assignment to memcpy when either will do.
5274 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5275 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5276 time an item is removed. No need to mark this function 'inline';
5277 the compiler knows better than we do.
5279 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5281 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5282 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5283 to change_frame_size (Bug#12388).
5284 (windowDidResize:): Pass YES to updateFrameSize.
5286 * nsterm.h: Add delay parameter to updateFrameSize.
5288 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5290 Discard killed buffers from deleted window and frame objects.
5291 This reduces an amount of references to killed buffers and
5292 helps GC to reclaim them faster.
5293 * alloc.c (discard_killed_buffers): New function.
5294 (mark_object): Use it for deleted windows and frames.
5295 (mark_object): If symbol's value is set up for a killed buffer
5296 or deleted frame, restore its global binding.
5297 * data.c (swap_in_global_binding): Add GC notice.
5298 (swap_in_symval_forwarding): Use convenient set_blv_where.
5299 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5300 * window.h: ... to here.
5302 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5304 Convenient macro to check whether the buffer is live.
5305 * buffer.h (BUFFER_LIVE_P): New macro.
5306 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5307 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5309 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5311 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5312 composition cases (Bug#12364).
5314 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5315 overhang of succeeding glyphs overlapping box cursor.
5317 * w32term.c (x_draw_glyph_string): Likewise.
5319 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5321 Simplify, document, and port floating-point (Bug#12381).
5322 The porting part of this patch fixes bugs on non-IEEE platforms
5323 with frexp, ldexp, logb.
5324 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5326 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5327 support, by removing commented-out code and briefly listing the
5328 C89 functions excluded. The commented-out stuff was confusing
5329 maintenance, e.g., we thought we needed cbrt but it was commented out.
5330 (logb): Remove decl; no longer needed.
5331 (isfinite): New macro, if not already supplied.
5332 (isnan): Don't replace any existing macro.
5333 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5334 are present on all C89 platforms.
5335 (Ffrexp): Do not special-case zero, as frexp does the right thing
5337 (Flogb): Do not use logb, as it doesn't have the desired meaning
5338 on hosts that use non-base-2 floating point. Instead, stick with
5339 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5340 frexp, to avoid getting an unspecified result.
5342 * xdisp.c (Qinhibit_debug_on_message): Now static.
5344 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5346 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5347 NSBezierPath (Bug#12131).
5349 2012-09-10 Chong Yidong <cyd@gnu.org>
5351 * fns.c (Fdelq, Fdelete): Doc fix.
5353 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5355 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5356 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5358 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5360 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5361 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5364 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5366 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5367 left fringe if the window has a left margin. This avoids leaving
5368 traces of the cursor because its leftmost pixel is not drawn over.
5370 * dispnew.c (update_window_line): When the left margin area of a
5371 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5372 that screen line. (Bug#12277)
5374 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5376 Assume C89 or later for math functions (Bug#12381).
5377 This simplifies the code, and makes it a bit smaller and faster,
5378 and (most important) makes it easier to clean up signal handling
5379 since we can stop worring about floating-point exceptions in
5380 library code. That was a problem before C89, but the problem
5381 went away many years ago on all practical Emacs targets.
5382 * data.c, image.c, lread.c, print.c:
5383 Don't include <math.h>; no longer needed.
5384 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5385 might be autoconfigured, as that never happens.
5387 * doprnt.c (DBL_MAX_10_EXP):
5388 * print.c (DBL_DIG):
5389 Remove. C89 or later always defines these.
5390 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5391 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5392 (arith_error, domain_error, domain_error2):
5393 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5394 no longer needed -- we simply return what C returns. All uses removed.
5395 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5397 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5398 Remove. All uses expanded, as these macros are no longer used
5399 more than once and are now more trouble than they're worth.
5400 (Ftan): Use tan, not sin / cos.
5401 (Flogb): Assume C89 frexp.
5402 (fmod_float): Assume C89 fmod.
5403 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5404 (init_floatfns): Remove. All uses removed.
5406 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5408 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5409 compositeToPoint for OSX < 10.6 (Bug#12390).
5411 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5413 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5414 This produces more-accurate results.
5416 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5418 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5419 changes (Bug#12088).
5421 2012-09-08 Chong Yidong <cyd@gnu.org>
5423 * syntax.c (Fstring_to_syntax): Doc fix.
5425 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5427 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5428 in the internal border.
5429 (x_set_window_size): Remove static variables and their usage.
5430 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5431 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5432 Remove fringe/internal border adjustment (Bug#11052).
5433 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5434 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5435 (ns_fix_rect_ibw): Remove.
5436 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5437 (ns_dumpglyphs_box_or_relief): Ditto.
5438 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5440 (ns_dumpglyphs_image): Ditto.
5441 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5443 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5444 their usage. Add fringe_extended_p and its use as in other terms.
5445 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5446 scroll bar was removed.
5447 (updateFrameSize): New function.
5448 (windowDidResize): Move code to updateFrameSize and call it.
5450 * nsterm.h (EmacsView): Add updateFrameSize.
5452 2012-09-07 Chong Yidong <cyd@gnu.org>
5454 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5456 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5458 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5460 More signal-handler cleanup (Bug#12327).
5461 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5462 Problem introduced when merging patches. Noted by Eli Zaretskii in
5463 <http://bugs.gnu.org/12327#67>.
5464 * floatfns.c: Comment fix.
5465 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5466 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5467 and anyway the declaration is harmless even if SIGDANGER is not defined.
5468 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5469 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5470 source files not surprisingly expected syssignal.h to define, or
5471 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5472 Include <sys/ioctl.h>, for FIONREAD.
5473 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5474 This eliminates a problem whereby other files mysteriously had
5475 to include "syssignal.h" before including "systty.h" if they
5476 wanted to use "#ifdef SIGIO".
5478 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5480 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5482 * w32.c (sigemptyset): Empty the set.
5483 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5485 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5487 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5489 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5490 (mark_object): Likewise for frame objects.
5492 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5494 * syssignal.h (handle_on_main_thread): Always declare,
5495 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5496 This ports to platforms without HAVE_PTHREAD.
5498 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5500 Signal-handler cleanup (Bug#12327).
5501 Emacs's signal handlers were written in the old 4.2BSD style with
5502 sigblock and sigmask and so forth, and this led to some
5503 inefficiencies and confusion. Rewrite these to use
5504 pthread_sigmask etc. without copying signal sets around. Also,
5505 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5506 'signal', and instead use functions that do not attempt to take
5507 over the system name space. This patch causes Emacs's text
5508 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5509 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5510 Do not include <signal.h> or "syssignal.h", as these
5511 modules do not use signals.
5512 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5513 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5514 Do not include <signal.h>, as "syssignal.h" does that for us now.
5515 * atimer.c (sigmask_atimers): New function.
5516 (block_atimers, unblock_atimers): New functions,
5517 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5519 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5520 no longer needed here.
5521 * emacs.c (main): Inspect existing signal handler with sigaction,
5522 so that there's no need to block and unblock SIGHUP.
5523 * sysdep.c (struct save_signal): New member 'action', replacing
5524 old member 'handler'.
5525 (save_signal_handlers, restore_signal_handlers):
5526 Use sigaction instead of 'signal' to save and restore.
5527 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5528 New function. All users of 'signal' modified to use set_sighandler
5529 if they're writeonly, and to use sys_signal if they're read+write.
5530 (emacs_sigaction_init, forwarded_signal): New functions.
5531 (sys_signal): Remove. All uses replaced by calls to sigaction
5532 and emacs_sigaction_init, or by direct calls to 'signal'.
5533 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5534 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5535 all uses replaced by pthread_sigmask etc. calls.
5536 * syssignal.h: Include <signal.h>.
5537 (emacs_sigaction_init, forwarded_signal): New decls.
5538 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5539 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5540 (sigmask, sys_sigmask): Remove; no longer needed.
5541 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5542 (sigblock, sigunblock, sigfree):
5543 (sigsetmask) [!defined sigsetmask]:
5544 Remove. All uses replaced by pthread_sigmask.
5545 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5546 no longer need to be replaced, and its typical old uses
5547 are now done via emacs_sigaction_init and sigaction.
5548 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5549 (sys_sigdel): Remove; unused.
5550 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5552 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5554 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5555 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5557 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5559 Explicitly mark buffer_defaults and buffer_local_symbols.
5560 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5561 mark_local_symbols here.
5562 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5563 since special buffers aren't marked here any more.
5564 (allocate_buffer): Chain new buffer with all_buffers here...
5565 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5567 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5568 (syms_of_buffer): Remove staticpro of the above.
5569 (init_buffer_once): Set names for buffer_defaults and
5570 buffer_local_symbols.
5572 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5574 Use bool for booleans in font-related modules.
5575 * font.c (font_intern_prop, font_style_to_value)
5576 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5577 (generate_otf_features, font_check_otf_features, font_check_otf)
5578 (font_match_p, font_list_entities, font_at):
5579 * fontset.c (fontset_id_valid_p, reorder_font_vector
5580 (fontset_find_font, Fset_fontset_font)
5581 (face_suitable_for_char_p) [0]:
5582 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5583 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5584 (m17n_flt_initialized, ftfont_shape_by_flt):
5585 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5586 * nsfont.m (nsfont_draw):
5587 * w32font.c (w32font_draw):
5588 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5589 Use bool for booleans.
5590 * font.h: Adjust to above API changes.
5591 (struct font, struct font_driver, struct font_driver_list):
5592 Use bool for booleans.
5593 (struct font): Remove useless member encoding_type.
5595 * fontset.c, xftfont.c: Omit unnecessary static decls.
5597 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5599 * alloc.c (mark_object): Revert window marking code
5600 since it's unsafe for the Fset_window_configuration.
5602 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5604 Fix race conditions with signal handlers and errno (Bug#12327).
5605 Be more systematic about preserving errno whenever a signal
5606 handler returns, even if it's not in the main thread. Do this by
5607 renaming signal handlers to distinguish between signal delivery
5608 and signal handling. All uses changed.
5609 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5610 * data.c (deliver_arith_signal): Rename from arith_error.
5611 * dispnew.c (deliver_window_change_signal): Rename from
5612 window_change_signal.
5613 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5614 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5615 * keyboard.c (deliver_input_available_signal): Rename from
5616 input_available_signal.
5617 (deliver_user_signal): Rename from handle_user_signal.
5618 (deliver_interrupt_signal): Rename from interrupt_signal.
5619 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5620 (deliver_child_signal): Rename from sigchld_handler.
5621 * atimer.c (handle_alarm_signal):
5622 * data.c (handle_arith_signal):
5623 * dispnew.c (handle_window_change_signal):
5624 * emacs.c (handle_fatal_signal, handle_danger_signal):
5625 * keyboard.c (handle_input_available_signal):
5626 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5627 * process.c (handle_pipe_signal, handle_child_signal):
5628 New functions, with the actual signal-handling code taken from the
5629 original respective signal handlers, sans the sporadic attempts to
5630 preserve errno, since that's now done by handle_on_main_thread.
5631 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5632 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5633 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5635 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5636 Move initialization of main_thread to sysdep.c's init_signals.
5637 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5638 our usage, and simplifies the mainline code.
5639 (record_child_status_change): New static function, as a helper
5640 for handle_child_signal, and with most of the old child handler's
5642 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5643 (handle_child_signal): Use the above.
5644 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5645 Moved here from emacs.c.
5646 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5647 code moved here from emacs.c's main function.
5648 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5649 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5650 This lets callers save and restore errno properly.
5652 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5654 Remove redundant or unused things here and there.
5655 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5656 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5657 * editfns.c (Fcompare_buffer_substrings): Likewise.
5658 * frame.h (struct terminal, struct font_driver_list):
5659 Remove redundant declarations.
5660 * window.h (Qleft, Qright): Likewise.
5662 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5664 Do not mark objects from deleted buffers, windows and frames.
5665 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5666 (mark_object): Likewise for windows and frames.
5668 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5670 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5671 buffer_defaults and buffer_local_symbols as valid objects.
5672 Return special value to denote them.
5674 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5676 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5677 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5678 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5679 (file_name_absolute_p, Fsubstitute_in_file_name):
5680 (check_executable, check_writable, Ffile_accessible_directory_p)
5681 (Fset_file_selinux_context, Fdefault_file_modes)
5682 (Finsert_file_contents, choose_write_coding_system)
5683 (Fwrite_region, build_annotations, a_write, e_write)
5685 * filelock.c (boot_time_initialized, get_boot_time)
5686 (get_boot_time_1, lock_file_1, within_one_second):
5687 * floatfns.c (in_float):
5688 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5689 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5690 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5691 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5692 * window.c (compare_window_configurations):
5693 Use bool for booleans.
5694 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5695 (Fdefault_file_modes): Now mode_t, not int, for modes.
5696 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5697 (internal_delete_file): Now returns void, not a (boolean) int,
5698 since nobody was looking at the return value.
5699 * lisp.h, window.h: Adjust to above API changes.
5701 * xdisp.c (set_message): Simplify and reindent last change.
5703 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5705 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5707 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5709 * eval.c (call_debugger): Make the function non-static so that we
5710 can call it from set_message.
5712 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5713 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5715 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5717 Give more-useful info on a fatal error (Bug#12328).
5718 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5719 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5720 of doing the work ourselves.
5721 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5722 do most of the work.
5723 (fatal_error_backtrace): New function, taken from the guts
5724 of the old fatal_error_signal, but with a new option to output
5726 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5727 info about the signal than just its number.
5728 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5729 * sysdep.c: Include <execinfo.h>
5730 (emacs_backtrace): New function, taken partly from the previous
5731 code of the 'die' function.
5732 (emacs_abort): Call fatal_error_backtrace rather than abort.
5734 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5736 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5737 eager (load-time) macro-expansion.
5738 * lisp.mk (lisp): Add macroexp.
5740 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5742 Simplify redefinition of 'abort' (Bug#12316).
5743 Do not try to redefine the 'abort' function. Instead, redo
5744 the code so that it calls 'emacs_abort' rather than 'abort'.
5745 This removes the need for the NO_ABORT configure-time macro
5746 and makes it easier to change the abort code to do a backtrace.
5747 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5748 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5749 Remove; sysdep.c's emacs_abort now takes its place.
5750 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5751 'abort' changed to use 'emacs_abort'.
5752 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5753 (abort) [!defined abort]: Rename to ...
5754 (emacs_abort): ... new name.
5755 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5756 the place of the old 'abort' in emacs.c.
5757 * w32.c, w32fns.c (abort): Do not #undef.
5758 * w32.c (emacs_abort): Rename from w32_abort.
5760 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5762 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5763 offsets[j].dv, since the y axis of the screen coordinates points
5764 down, while the y axis of the font definition coordinates points
5765 up. This fixes display of Arabic diacritics such as KASRA and
5766 KASRATAN. (Bug#11860)
5768 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5770 Be more systematic about _setjmp vs setjmp.
5771 * alloc.c (test_setjmp, mark_stack):
5772 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5773 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5774 (png_load, my_error_exit, jpeg_load):
5775 * process.c (send_process_trap, send_process):
5776 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5777 The underscored versions are up to 30x faster on some hosts.
5778 Formerly, the code used setjmp+longjmp sometimes and
5779 _setjmp+_longjmp at other times, with no particular reason to
5780 prefer setjmp+longjmp.
5782 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5784 Fix minor problem found by static checking.
5785 * buffer.c (Fdelete_all_overlays): Return nil.
5787 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5789 * buffer.c (Fdelete_all_overlays): New function.
5791 2012-09-03 Chong Yidong <cyd@gnu.org>
5793 * gtkutil.c: Add extern decl for Qxft.
5795 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5797 * emacs.c, eval.c: Use bool for boolean.
5798 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5799 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5800 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5801 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5802 (main, decode_env_path, Fdaemon_initialized):
5803 * eval.c (call_debugger, Finteractive_p, interactive_p):
5804 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5805 (maybe_call_debugger, Fbacktrace):
5806 * process.c (read_process_output, exec_sentinel):
5807 Use bool for booleans.
5808 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5809 All callers changed.
5810 * eval.c (interactive_p): Omit always-true boolean argument
5811 EXCLUDE_SUBRS_P. All callers changed.
5812 * dispextern.h, lisp.h: Reflect above API changes.
5813 * firstfile.c (dummy): Use the address of 'main', whose signature
5814 won't change, instead of the address of 'initialize', whose
5815 signature just changed from int to bool.
5816 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5817 * msdos.c (fatal_error_in_progress): ... from here.
5818 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5820 (redisplay_internal, unwind_redisplay): Simply clear
5821 REDISPLAYING_P when unwinding, instead of saving its previous,
5822 always-false value and then restoring it.
5824 Clean up some extern decls.
5825 Mostly, this hoists extern decls out of .c files and into .h files.
5826 That way, we're more likely to catch errors if the interfaces change.
5827 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5828 declare xg_mark_data.
5829 * dispextern.h (x_frame_parm_handlers):
5831 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5832 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5833 (Qultra_bold, Qoblique, Qitalic):
5834 Move extern decl here from .c file.
5835 * alloc.c (xg_mark_data) [USE_GTK]:
5837 * eval.c (Qlexical_binding):
5838 * fns.c (time) [!HAVE_UNISTD_H]:

5844 * process.c (QCfamily, QCfilter):
5845 * widget.c (free_frame_faces):
5846 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5847 * xfont.c (x_clear_errors):
5848 * xterm.c (x_frame_parm_handlers):
5849 Remove now-redundant extern decls.
5850 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5851 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5853 * xfaces.c: Remove unnecessary static decls.
5854 * xterm.c (updating_frame): Remove decl of nonexistent object.
5856 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5857 when building globals.h, as the objects that are not built on
5858 this host are not needed to compile C files on this host.
5860 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5862 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5864 * frame.h: Add missing prototype for x_wm_set_size_hint.
5866 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5870 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5871 (Fsubstitute_command_keys):

5876 (make_buffer_string, make_buffer_string_both)
5877 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5889 (set_intervals_multibyte_1, set_intervals_multibyte):
5890 * keyboard.c (decode_timer):
5891 Use bool for boolean.
5892 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5893 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5895 2012-09-02 Chong Yidong <cyd@gnu.org>
5897 * keymap.c (push_key_description): Print M-TAB as C-M-i
5900 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5902 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5903 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5904 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5908 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5910 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5912 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5913 more than one grapheme cluster passed to the shaper: compute the
5914 offset adjustment values separately for each cluster. (Bug#11860)
5916 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5917 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5918 about implicit conversions from integer to pointer.

6237 Special MEM_TYPE_SPARE to denote reserved memory.
6238 * alloc.c (enum mem_type): New memory type.
6239 (refill_memory_reserve): Use new type for spare memory.

6273 * character.h, charset.h: Adjust to match previous changes.
6274 * character.h (char_printable_p): Remove decl of nonexistent function.
6275 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6276 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6277 are all boolean, so make them single-bit bitfields.
6279 * lisp.h (ASET): Remove attempt to detect side effects.
6280 It was meant to be temporary and it often doesn't work,
6281 because when IDX has side effects the behavior of IDX==IDX
6282 is undefined. See Stefan Monnier in
6283 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6285 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6288 (FUNCTIONP): Use it.

6293 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6294 as that's faster and simpler than static storage. Don't bother
6295 with the g_main_context_query overhead if g_main_context_pending
6296 says no events are pending.
6297 (gfds, gfds_size): Remove these static vars.
6298 (xgselect_initialize): Remove; no longer needed.
6299 All uses and decls removed.
6301 * emacs.c (fatal_error_signal_hook): Remove.
6302 All uses removed. This leftover from old code was always 0.
6304 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

6329 Use bool for booleans, instead of int.
6330 * lisp.h, process.h: Adjust prototypes to match above changes.
6331 * callint.c (Fcall_interactively): Don't assume the mark's
6332 offset fits in 'int'.
6334 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>

6345 Use bool for booleans, instead of int.
6346 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6347 since the 1-or-0 return value is always ignored anyway.
6348 (mmap_initialized_p):
6349 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6350 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6352 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6354 * bidi.c: Use bool for boolean.
6355 This is a bit more readable, and makes the text segment of bidi.o
6356 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6357 Presumably it's faster too.

6374 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6376 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6377 * atimer.h: Include <stdbool.h>.
6379 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6381 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6382 compile time tests instead of run time tests on systems that do
6384 (FRAME_MAC_P): Remove leftover from deleted code.
6385 * frame.c (syms_of_frame): Remove leftover from deleted code.
6387 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6389 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6391 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6393 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6394 Otherwise, the compiler complains about (A?B:C) where B is void
6395 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6396 (fontset_add): Return void, for FONTSET_ADD.
6398 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6400 * alloc.c: Use bool for booleans.
6401 (gc_in_progress, abort_on_gc)
6402 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6403 (dont_register_blocks) [GC_MALLOC_CHECK]:
6404 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6405 (check_string_bytes, make_specified_string, memory_full)
6406 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6407 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6408 (mark_stack, valid_pointer_p, make_pure_string)
6409 (Fgarbage_collect, survives_gc_p, gc_sweep):
6410 Use bool for booleans, instead of int.
6411 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6412 Remove unused local.
6413 * alloc.c (PURE_POINTER_P):
6414 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6415 * editfns.c (Fformat):
6416 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6418 * fns.c (sweep_weak_table):
6419 * lisp.h (suppress_checking, push_message, survives_gc_p)
6420 (make_pure_string, gc_in_progress, abort_on_gc):
6421 * lread.c (readchar, read1):
6422 * print.c (Fprin1_to_string):
6423 * xdisp.c (push_message):
6424 Use bool for booleans affected directly or indirectly by
6427 Make recently-introduced setters macros.
6428 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6429 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6430 (set_fontset_default, set_fontset_fallback): Rename from their
6431 upper-case counterparts, and make them functions rather than macros.
6432 This is more consistent with the other recently-introduced setters.
6433 These don't need to be inline, since they're local.
6435 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6437 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6438 the loop (Bug#12247).
6440 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6442 * lisp.h (vcopy): Use memcpy rather than our own loop.
6443 This fixes a performance regression introduced by the recent
6444 addition of vcopy. This means 'vcopy' will need to be modified
6445 for a copying collector, but that's OK. Also, tighten the
6446 checking in the assertion.
6448 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6450 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6451 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6452 non-base glyph for the width of the base character, according to
6453 what x_draw_composite_glyph_string_foreground expects.
6454 Generate WADJUST value according to composition_gstring_width's
6455 expectations, to produce correct width of the composed character.
6456 Reverse the sign of the DU offset produced by ScriptPlace.
6458 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6460 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6462 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6464 Avoid direct writes to contents member of struct Lisp_Vector.
6465 * lisp.h (vcopy): New function to copy data into vector.
6466 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6467 * fns.c (Ffillarray): Use ASET.
6468 * keyboard.c (timer_check_2): Use AREF and ASET.
6469 (append_tool_bar_item, Frecent_keys): Use vcopy.
6470 * lread.c (read_vector): Use ASET.
6471 * msdos.c (Frecent_doskeys): Use vcopy.
6472 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6473 (Finternal_merge_in_global_face): Use ASET and vcopy.
6474 * xfont.c (xfont_list_pattern): Likewise.
6476 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6478 * window.c (Fwindow_point): For the selected window always return
6479 the position of its buffer's point.
6480 (Fset_window_point): For the selected window always go in its
6481 buffer to the specified position.
6483 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6485 Setter macros for fontsets.
6486 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6487 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6488 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6491 2012-08-20 Glenn Morris <rgm@gnu.org>
6493 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6494 Don't assume that `ln -f' works.
6496 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6498 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6499 and later about non-assignments with no effect. See discussion at
6500 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6503 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6505 Inline setter functions for Lisp_Objects slots of struct specbinding.
6506 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6509 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6511 * window.c (select_window): Always make selected window's buffer
6514 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6516 Use AREF and ASET for docstrings of category tables.
6517 * category.h (CATEGORY_DOCSTRING): Use AREF.
6518 (SET_CATEGORY_DOCSTRING): Use ASET.
6519 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6521 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6523 Inline setter functions for hash table members.
6524 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6525 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6526 (set_hash_key_and_value, set_hash_index, set_hash_next)
6527 (set_hash_hash): New functions.
6528 * charset.c, fns.c: Adjust users.
6530 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6532 Inline getter and setter functions for per-buffer values.
6533 * buffer.h (per_buffer_default, set_per_buffer_default)
6534 (per_buffer_value, set_per_buffer_value): New functions.
6535 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6536 * buffer.c, data.c: Adjust users.
6538 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6540 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6542 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6544 Rely on <config.h> + <unistd.h> to declare 'environ',
6545 as gnulib does this if the system doesn't.
6546 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6547 Remove declaration. MS-Windows declares it on stdlib.h which is
6548 included by conf_post.h.
6549 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6550 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6551 * vm-limit.c: Include <unistd.h>, for 'environ'.
6553 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6554 (start_of_data): Remove decl; mem-limits.h provides it.
6556 * xdisp.c (handle_invisible_prop): Make it a bit faster
6557 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6559 2012-08-19 Chong Yidong <cyd@gnu.org>
6561 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6564 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6566 * .gdbinit: Use call instead of set when calling a function in the
6569 * data.c (set_internal): Don't use set_blv_found.
6570 (Fkill_local_variable): Likewise.
6572 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6574 * nsfont.m (ns_ascii_average_width): Ensure the string
6575 ascii_printable is initialized with a null-terminated character
6576 array. Otherwise, it can contain undesired extra characters.
6578 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6580 port new setting code to Sun C 5.8 2005/10/13
6581 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6582 Return void, not Lisp_Object. Otherwise, the compiler
6583 complains about (A?B:C) where B is void and C is Lisp_Object
6584 when compiling CHAR_TABLE_SET, due to the recent change to
6585 the API of sub_char_table_set_contents.
6587 2012-08-18 Chong Yidong <cyd@gnu.org>
6589 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6590 for the string case (Bug#3874).

6745 The old version was confusing because it used the same name
6746 'parent' for two different things.
6748 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6750 Functions to get and set Lisp_Object fields of buffer-local variables.

6759 font spec, make the font's attributes take precedence over
6760 directly-specified attributes.
6761 (merge_face_ref): Recognize :font.
6763 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

7417 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7418 * w32.c (init_environment): Change the default values of many
7419 environment variables in dflt_envvars[] to NULL, to avoid pushing
7420 them into environment when they were not already defined.
7421 Remove the code that deletes site-lisp subdirectories from the default
7422 value of EMACSLOADPATH, as it is no longer needed.
7423 (check_windows_init_file): Now external, not static.
7424 Use Vload_path as is, without adding anything, as this function is now
7425 called when Vload_path is already set up.
7427 * w32.h (check_windows_init_file): Add prototype.
7429 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7436 installation tree, as appropriate.
7438 * callproc.c (init_callproc_1): Call decode_env_path instead of
7439 doing its equivalent by hand.
7440 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
7441 the code that sets Vexec_path run on MS-Windows.
7443 * lread.c (init_lread): Add comments to #ifdef's.
7445 * msdos.c (dos_set_window_size, IT_update_begin)

7457 Remove unnecessary casts involving pointers.
7458 These casts are no longer needed now that we assume C89 or later,

7472 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7473 Remove unnecessary pointer casts.
7474 * alloc.c (record_xmalloc): New function.
7475 * lisp.h (record_xmalloc): New decl.
7476 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7477 more like a function. This is because the pointer cast is not
7478 needed. All uses changed.
7479 * print.c (print_string, print_error_message): Avoid length recalc.
7481 Improve fix for macroexp crash with debugging (Bug#12118).
7482 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7483 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7484 not supposed to be invoked from the garbage collector.
7485 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7486 (gc_aset): New function, which is like ASET but can be
7487 used in the garbage collector.
7488 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7503 headers (most versions of MinGW w32api don't).
7504 (get_security_info, create_symbolic_link)
7505 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

7516 with addition of handling of symlinks and support for 'lstat'.
7517 If possible, get file's attributes and security information by
7518 handle, not by name. Produce S_IFLNK bit for symlinks, when
7519 called from 'lstat'.
7520 (stat, lstat): New functions, call 'stat_worker'.
7521 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7522 symlinks when the underlying filesystem supports them.
7524 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7526 Fix macroexp crash on Windows with debugging (Bug#12118).
7527 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7528 checking subscripts; problem introduced with the recent
7529 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7530 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7531 since it's used in non-static inline functions now.
7533 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7534 Don't assume buffer size fits in 'int'. Remove unused local.

7551 * category.c (CATEGORY_INLINE):
7552 * character.c (CHARACTER_INLINE):
7553 * charset.c (CHARSET_INLINE):
7554 * composite.c (COMPOSITE_INLINE):
7555 * dispnew.c (DISPEXTERN_INLINE):
7556 * sysdep.c (SYSTIME_INLINE):
7557 Define to EXTERN_INLINE, so that the corresponding functions
7558 are compiled into code.
7559 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7560 (INLINE_HEADER_END): New macros.
7561 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7581 hard-coding the path separator.
7583 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7585 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7586 This how ASET and AREF are supposed to work, and makes
7587 it easier to think about future improvements. See
7588 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7589 * charset.h (set_charset_attr): New function.

8081 the fix for 12036 would have avoided some of the problems noted in
8082 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8083 would have been more obvious.

8093 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8094 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8095 not be usable in #if. This simplifies things.
8097 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8099 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8104 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8105 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8106 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8107 Adjust to changes in lisp.h and emacs.c, by using

8110 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

8112 instead of gdb_valbits.
8113 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8114 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8115 instead of gdb_array_mark_flag.
8116 (xboolvector): Get size from $->size, not $->header.size.
8117 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8118 (xreload, hook-run, hookpost-run): Remove.
8119 * emacs.c: Include <verify.h>.
8120 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8121 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):

9015 * nsterm.m: Include <ftoastr.h>.
9017 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9018 Prefer snprintf to strncpy.
9019 * nsterm.m (ns_term_init):
9020 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9021 * nsterm.m (ns_term_init):
9022 Avoid the need for strncpy, by using build_string or
9023 make_unibyte_string directly. Use dtoastr, not snprintf.
9024 * process.c (Fmake_network_process): Diagnose service names that
9025 are too long, rather than silently truncating them or creating
9026 non-null-terminated names.

9056 Optimize pure C strings initialization.
9057 * lisp.h (make_pure_string): Fix prototype.
9058 (build_pure_c_string): New function, defined as static inline. This
9059 provides a better opportunity to optimize away calls to strlen when
9060 the function is called with compile-time constant argument.
9061 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9062 argument, adjust users accordingly. Use build_pure_c_string where
9064 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9065 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9066 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9068 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9070 Avoid calls to strlen in miscellaneous functions.
9071 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

9093 * s/gnu.h (DATA_START): Move definitions to configure.
9095 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9096 We include usg5-4-common.h, which defines them both.
9098 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9099 O_RDONLY already includes it).
9101 Stop ns builds setting the EMACSLOADPATH environment variable.
9102 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9103 Now it does not set EMACSLOADPATH, just returns the load-path string.
9104 * nsterm.h: Update accordingly.
9105 * lread.c [HAVE_NS]: Include nsterm.h.
9106 (init_lread) [HAVE_NS]: Use ns_load_path.

9109 2012-07-09 Glenn Morris <rgm@gnu.org>
9111 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9112 since the included bsd-common.h does so.
9114 Stop ns builds setting the EMACSPATH environment variable.
9115 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9116 (ns_init_paths): Do not set EMACSPATH.
9117 * nsterm.h (ns_exec_path): Add it.
9118 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9121 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9123 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9125 * process.c (wait_reading_process_output): 'waitchannels' was unset
9126 when read_kbd || !NILP (wait_for_cell); fix this.
9128 Add GCC-style 'const' attribute to functions that can use it.
9129 * character.h (char_resolve_modifier_mask):
9130 * keyboard.h (make_ctrl_char):
9131 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9140 Add decls with ATTRIBUTE_CONST.
9142 Minor improvements to make_formatted_string.
9143 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9144 where int is good enough, as vsprintf returns an int.
9145 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9147 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9149 Use make_formatted_string to avoid double length calculation.

9176 Move marker debugging code under MARKER_DEBUG.
9177 * marker.c (MARKER_DEBUG): Move marker debugging code under
9178 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9179 for bootstrap with --enable-checking (~3x slowdown reported
9180 by Juanma Barranquero <lekktu@gmail.com>).
9181 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9183 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9185 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9186 See <http://bugs.gnu.org/11825#29>.
9188 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9190 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9191 has no font, use the frame's font. (Bug#11813)
9192 (display_line): Add commentary about displaying truncation glyphs
9194 (produce_special_glyphs): Move here from term.c.
9196 * term.c (produce_special_glyphs): Move to xdisp.c.
9198 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9201 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9203 * xdisp.c (display_line): Avoid warning about implicit declaration
9206 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9208 * lisp.h: Remove empty conditional.
9210 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9212 * lread.c (load_path_check): Now static.
9214 Fix some minor --with-ns problems found by static checking.
9215 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9216 (x_set_font) [!HAVE_X_WINDOWS]:
9217 * image.c (xpm_load_image) [HAVE_NS]:
9218 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9219 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9220 Remove unused local.
9221 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9222 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9223 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9224 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9225 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9226 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:

9229 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9231 2012-07-07 Glenn Morris <rgm@gnu.org>
9233 * lread.c (load_path_check): New function, split from init_lread.
9234 (init_lread): Reorganize. Motivation:
9235 If EMACSLOADPATH is set, check/warn about that rather than the
9236 defaults, which we are not going to use. Hence we can remove
9237 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9238 Don't warn if site-lisp directories are missing.
9239 If not installed, start from a blank load-path, since
9240 PATH_LOADSEARCH refers to the eventual installation directories.
9242 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9244 Support truncation and continuation glyphs on GUI frames, when
9245 fringes are disabled. (Bug#11832)
9246 * xdisp.c (init_iterator): Get dimensions of truncation and
9247 continuation glyphs even if on GUI frames.
9248 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9249 or both, are absent.
9250 (start_display, move_it_in_display_line_to): Handle the case of a
9251 GUI frame without a fringe to display continuation or truncation
9253 (insert_left_trunc_glyphs): Support GUI frames: make sure
9254 truncation glyphs overwrite enough glyphs from the current line to
9255 have sufficient space in pixels.
9256 (display_line): Support truncation and continuation glyphs on GUI
9257 frames. If some spare pixels are left on the line after inserting
9258 the truncation glyphs, fill that space with a stretch glyph of a
9259 suitably computed width.
9261 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9262 produce_glyphs, to support GUI sessions.
9264 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9266 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9268 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9270 Do not require float-time's arg to fit in time_t (Bug#11825).
9271 This works better on hosts where time_t is unsigned, and where
9272 float-time is applied to the (negative) difference between two times.
9273 * editfns.c (decode_time_components): Last arg is now double *,
9274 not int *, and means to store all the result as a double, without
9275 worrying about whether the seconds part fits in time_t.
9276 All callers changed.
9277 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9278 All callers changed.
9279 (Ffloat_time): Do not fail merely because the specified time falls
9280 outside of time_t range.
9282 2012-07-07 Glenn Morris <rgm@gnu.org>
9284 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9299 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9300 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9301 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

9304 * xfont.c (compare_font_names): Redo to omit the need for casts.
9306 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9308 * xfns.c (Fx_change_window_property): Doc fix.
9309 * w32fns.c (Fx_change_window_property): Doc fix.
9311 * w32fns.c (Fx_window_property): Accept the same arguments as the
9312 X Windows version. Doc fix.
9313 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9315 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9316 Eli Zaretskii <eliz@gnu.org>
9318 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9319 Windows-specific code from nt/config.nt moved here.
9320 Obsolete settings removed.
9322 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9324 * process.c: Avoid unnecessary calls to gettime.
9325 (wait_reading_process_output): Don't get the time of day
9326 when gobbling data immediately and not waiting, as there's no need
9327 for it in that case. This removes a FIXME.
9329 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9331 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9332 is defined (Bug#11768).
9334 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9336 Fix marker debugging code.
9337 * marker.c (byte_char_debug_check): Do not perform the check
9338 if buffer is not multibyte.
9339 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9340 Call byte_char_debug_check with correct arguments.
9342 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9344 Compile marker debugging code only if ENABLE_CHECKING is defined.
9345 * marker.c (byte_char_debug_check, count_markers):
9346 Use only if ENABLE_CHECKING is defined.
9347 (byte_debug_flag): Remove.
9348 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9349 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9351 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9353 Avoid code repetition in marker-related functions.
9354 * marker.c (attach_marker): New function.
9355 (Fset_marker, set_marker_restricted, set_marker_both)
9356 (set_marker_restricted_both): Use it.
9357 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9358 Consistently rename charno to charpos.
9359 (marker_position): Add eassert.
9360 (marker_byte_position): Convert to eassert.

9379 * window.c (save_window_save): Likewise.
9381 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9383 Do not use Fdelete_overlay in delete_all_overlays
9384 to avoid redundant calls to unchain_overlay.
9385 * buffer.c (drop_overlay): New function.
9386 (delete_all_overlays, Fdelete_overlay): Use it.
9387 * minibuf.c (get_minibuffer): Fix comment.

9391 Port to OpenBSD 5.1 amd64.
9392 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9393 This is needed for OpenBSD, and should be harmless on all BSD systems.
9394 Also, include <sys/sysctl.h>, as it should be available on all
9395 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9396 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9397 use p_pid member, not kp_proc.pid.
9399 2012-07-06 Glenn Morris <rgm@gnu.org>
9401 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9403 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9405 More xmalloc and related cleanup.

9414 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9416 Omit needless casts involving void * pointers and allocation.
9417 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9418 as the former is more robust if P's type is changed.
9419 Prefer xzalloc to xmalloc + memset 0.
9420 Simplify malloc-or-realloc to realloc.
9421 Don't worry about xmalloc returning a null pointer.
9422 Prefer xstrdup to xmalloc + strcpy.
9423 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9425 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9426 alloca of a constant.
9428 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9430 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9431 hscroll is larger than the line width. Fixes long and futile
9432 looping inside extend_face_to_end_of_line (on a TTY) producing
9433 glyphs that are not needed and thrown away.
9435 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9437 * marker.c (set_marker_restricted_both): Simplify by using
9440 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9463 * xdisp.c (window_hscroll_limited): New function.
9464 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9465 coordinates when window's hscroll is set to insanely large

9531 * fileio.c (time_error_value): Check the right error number.
9532 Problem reported by Troels Nielsen in
9533 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9535 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9537 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9538 This should be fixed in a better way; see Eli Zaretskii in
9539 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9540 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9542 * fileio.c (time_error_value): Rename from special_mtime.
9543 The old name's problems were noted by Eli Zaretskii in
9544 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9546 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9547 This variable's comment says Emacs needs at least one GDB-visible
9548 symbol of type enum pvec_type, to work around GDB problems.
9549 The symbol's value doesn't matter.
9551 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9552 that causes compilation to fail on pre-C99 compilers.
9554 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9556 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9557 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9559 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9561 * buffer.c (init_buffer_once): Fix initialization of
9562 headers for buffer_defaults and buffer_local_symbols.
9563 Reported by Juanma Barranquero <lekktu@gmail.com>.
9565 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9567 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9568 * lisp.h (enum pvec_type): Use fewer bits.
9569 (PSEUDOVECTOR_SIZE_BITS): New constant.
9570 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9571 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9572 change in pvec_type.
9573 (PSEUDOVECTOR_TYPEP): New macro.
9574 (TYPED_PSEUDOVECTORP): Use it.
9575 * fns.c (internal_equal): Adapt code to extract pvectype.

9577 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9578 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9579 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9580 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9581 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9582 abusing vector->header.next.nbytes.
9583 (live_vector_p): Use PVEC_TYPE.
9584 (mark_object): Adapt code to extract pvectype. Use switch.
9586 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9588 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9589 Tighten new eassert a bit.
9591 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9593 Fix compilation with --enable-gcc-warnings and -O1
9595 * doprnt.c (doprnt): Change type of tem to int, initialize
9596 to avoid compiler warning. Add eassert.
9597 * search.c (simple_search): Initialize match_byte to avoid
9598 compiler warning. Add eassert.
9600 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9602 Avoid weird behavior with large horizontal scrolls.
9603 Without this change, for example, large hscroll values would
9604 mess up Emacs's display on Fedora 15 x86, presumably due to
9605 overflows in int calculations in the display code.
9606 Also, if buffers had long lines, Emacs would freeze.
9607 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9608 (set_window_hscroll): New function, containing the old guts of
9609 Fset_window_hscroll. Return the clipped value.
9610 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9611 This avoids the need to check against PTRDIFF_MAX.
9613 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9615 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9617 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9619 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9621 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9622 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9623 since GCC 4.4.6 issues a bogus warning for them.
9625 Fix bugs in file timestamp newness comparisons.
9626 * fileio.c (Ffile_newer_than_file_p):
9627 * lread.c (Fload): Use full timestamp resolution of files,
9628 not just the 1-second resolution, so that files that are only
9629 slightly newer still count as newer.
9630 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9631 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9633 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9635 * fileio.c: Improve handling of file time marker. (Bug#11852)
9636 (special_mtime): New function.
9637 (Finsert_file_contents, Fverify_visited_file_modtime):
9638 Use it to set special mtime values consistently.
9640 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9642 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9643 marker for non-existing file. (Bug#11852)
9645 2012-07-03 Glenn Morris <rgm@gnu.org>
9647 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9648 and did not make it into globals.h).
9650 2012-07-03 Tom Tromey <tromey@redhat.com>
9652 * window.c (Fset_window_margins, Fset_window_fringes)
9653 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9654 * textprop.c (Fprevious_property_change): No longer static.
9655 * syntax.c (Fsyntax_table_p): No longer static.

9686 * xterm.h: Remove EXFUN.
9688 2012-07-03 Glenn Morris <rgm@gnu.org>
9690 * lisp.h (Frandom): Make it visible to C.
9691 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9692 buffer for invisible buffers. (Bug#1229)
9694 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9696 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9697 values which aren't power of 2.
9698 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9699 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9702 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9704 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9706 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9708 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9710 * alloc.c (allocate_vector_block): Remove redundant
9711 calls to mallopt if DOUG_LEA_MALLOC is defined.
9712 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9713 avoid calls to mallopt if zero_vector is returned.
9715 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9717 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9718 is enabled, avoid dereferencing NULL current_sblock if
9721 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9723 Cleanup basic buffer management.
9724 * buffer.h (struct buffer): Change layout to use generic vector
9725 marking code. Fix some comments. Change type of 'clip_changed'
9726 to bitfield. Remove unused #ifndef old.
9727 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9728 (GET_OVERLAYS_AT): Fix indentation.
9729 (for_each_per_buffer_object_at): New macro.

9733 * alloc.c (allocate_buffer): Adjust to match new layout of
9734 struct buffer. Fix comment.
9735 (mark_overlay): New function.

9738 (mark_object): Use it. Adjust marking of misc objects
9739 and related comments.
9741 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9743 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9744 wrapper that is not needed because the wrapped code is a no-op (zero
9745 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9746 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9748 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9750 * alloc.c (mark_buffer): Simplify. Remove prototype.
9751 (mark_object): Add comment. Reorganize marking of vector-like
9752 objects. Use CHECK_LIVE for all vector-like objects except buffers
9753 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9754 Avoid redundant calls to mark_vectorlike for bool vectors.
9756 2012-06-30 Glenn Morris <rgm@gnu.org>
9758 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9760 * epaths.in (PATH_SITELOADSEARCH): New.
9761 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9762 This is rather than relying on --enable-locallisppath elements
9763 having "site-lisp" in their names. (Bug#10208#25, 11658)
9765 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9767 * w32proc.c (sys_select): Accept and ignore one more argument.
9769 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9771 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9772 (pselect) [!MS_DOS]: Redirect to sys_select.
9774 * sysdep.c: Don't include dos.h and dosfns.h.
9776 * process.c (sys_select):
9777 * msdos.c (sys_select): Accept one more argument and ignore it.
9779 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9780 adapt data types and code to that.
9783 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9784 which clashes with the gnulib function of the same name.
9786 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9788 * font.c (font_style_to_value, font_style_symbolic)
9789 (font_prop_validate_style): Add type checks for values in
9792 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9794 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9797 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9799 * xdisp.c (try_window_id): Undo last change.
9801 * w32.c (getwd): Adjust commentary about startup_dir.
9802 (init_environment): Always call sys_access, even in non-MSVC
9803 builds. Don't chdir to the directory of the Emacs executable.
9804 This undoes code from 1997 which was justified by the need to
9805 "avoid conflicts when removing and renaming directories". But its
9806 downside was that every relative file name was being interpreted
9807 relative to the directory of the Emacs executable, which can never
9808 be TRT. In particular, it broke sys_access when called with
9809 relative file names.
9810 (sys_access): Map GetLastError to errno.
9812 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9814 * window.h (struct window): Change type of 'fringes_outside_margins'

9818 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9821 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9823 * gnutls.c (emacs_gnutls_handshake):
9824 Add QUIT to make the loop interruptible.
9826 2012-06-29 Glenn Morris <rgm@gnu.org>
9828 * charset.c (init_charset): Make lack of etc/charsets fatal.
9830 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9832 * editfns.c (region_limit): Fix type mismatch.
9834 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9836 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9837 undefined. Convert from xassert to eassert.
9838 * nsmenu.m: Convert from xassert to eassert.
9839 * nsterm.m: Likewise.
9841 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9843 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9845 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9847 Avoid integer overflow on scroll-left and scroll-right.
9848 * window.c (HSCROLL_MAX): New macro.
9849 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9850 overflow when requested scroll falls outside ptrdiff_t range.
9852 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9854 * window.h (struct window): Change type of 'hscroll',
9855 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9856 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9857 Adjust users accordingly.
9858 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9859 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9860 from EMACS_INT to ptrdiff_t.
9861 (make_window): Omit redundant initialization.
9863 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9865 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9867 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9869 * window.h (struct window): Change type of 'use_time' and
9870 'sequence_number' from Lisp_Object to int.
9871 * frame.c (make_frame): Adjust users accordingly.
9872 * print.c (print_object): Likewise.
9873 * window.c (select_window, Fwindow_use_time, make_parent_window)
9874 (make_window): Likewise.
9876 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9878 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9879 enabled with --enable-checking=[all,glyphs] configure option.
9880 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9881 adjust comments accordingly.

9932 avoid GCC warning about unused macro.
9934 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9936 * alloc.c (allocate_string): Omit intervals initialization.
9937 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9938 as in make_pure_string and make_pure_c_string.
9940 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9942 * alloc.c (allocate_string): Fix last change.
9944 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9994 * alloc.c: Remove build_string.
9995 * lisp.h: Define build_string as static inline. This provides
9996 a better opportunity to optimize away calls to strlen when the
9997 function is called with compile-time constant argument.
9998 * image.c (imagemagick_error): Convert to build_string.
9999 * w32proc.c (sys_spawnve): Likewise.

10002 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10004 Use sprintf return value instead of invoking strlen on result.
10005 In the old days this wasn't portable, since some sprintf
10006 implementations returned char *. But they died out years ago and
10007 Emacs already assumes sprintf returns int.
10008 Similarly for float_to_string.
10009 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10010 * ccl.c (ccl_driver):
10011 * character.c (string_escape_byte8):

10014 * print.c (print_object):
10015 * xdisp.c (message_dolog):
10016 * xfns.c (syms_of_xfns):
10017 Use sprintf or float_to_string result to avoid need to call strlen.
10018 * data.c (Fnumber_to_string):
10019 Use make_unibyte_string, since the string must be ASCII.
10020 * lisp.h, print.c (float_to_string): Now returns int length.
10021 * term.c (produce_glyphless_glyph):
10022 Use sprintf result rather than recomputing it.
10024 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10025 * Makefile.in (ALL_CFLAGS):
10026 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10027 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10029 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10031 * dispextern.h (xstrcasecmp): Define to library function
10032 strcasecmp if available.
10033 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10035 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10037 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10039 * menu.c (push_submenu_start, push_submenu_end)
10040 (push_left_right_boundary, push_menu_pane): Likewise.
10041 * msdos.c (dos_rawgetc): Likewise.
10043 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>

10048 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10050 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10051 sprintf already null-terminates its output.
10053 * xfns.c (x_window): Remove redundant cast.
10055 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10057 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10058 `const char *' to `char *' to avoid compiler warning.
10060 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10062 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10063 instead of truncating it to 63 (admittedly a generous limit).
10065 * process.c: Fix spelling and caps in comments.
10067 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10069 * emacs.c (setpgrp): Remove definition, unused.

10079 (SYSTIME_H): Add nt/inc/sys/time.h.
10081 * systime.h [WINDOWSNT]: Include sys/time.h.
10083 * s/ms-w32.h (struct timespec): Definition moved from
10084 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10086 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10116 Remove unnecessary forward decls.
10118 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10120 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10121 * lisp.h (WAIT_READING_MAX): New macro.
10122 * dispnew.c (Fsleep_for, sit_for):
10123 * keyboard.c (kbd_buffer_get_event):
10124 * process.c (Faccept_process_output):
10125 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10126 This improves on the previous patch, which introduced a bug
10127 when time_t is unsigned and as wide as intmax_t.
10128 See <http://bugs.gnu.org/9000#51>.
10130 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10132 * dispnew.c (sit_for, Fsleep_for):
10133 * keyboard.c (kbd_buffer_get_event):

10146 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10147 Privately reported by Herbert J. Skuhra.
10148 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10150 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10151 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10153 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10155 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10156 last argument of make_unibyte_string.
10158 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10159 language ID in the event parameters.
10161 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10162 event.code, not the obscure "character set ID".
10164 2012-06-23 Chong Yidong <cyd@gnu.org>
10166 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10189 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10190 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10191 Don't assume EMACS_TIME and struct timeval are the same type.
10193 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10195 Support higher-resolution time stamps (Bug#9000).
10196 The time stamps are only nanosecond-resolution at the C level,
10197 since that's the best that any real-world system supports now.
10198 But they are picosecond-resolution at the Lisp level, as that's
10199 easy, and leaves room for future OS improvements.
10201 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10204 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10205 Don't get current time unless it's needed.
10207 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10208 now provides it if it's absent.
10209 (start_atimer): Port to higher-res time stamps.
10210 Check for time stamp overflow. Don't get current time more
10211 often than is needed.
10213 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10214 Include systime.h, not time.h.
10215 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10217 * dired.c: Include stat-time.h.
10218 (Ffile-attributes): File times now have higher resolution.
10220 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10221 (struct image): Timestamp now has higher resolution.
10223 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10224 has at least microseconds now. All uses removed.
10225 (update_frame, update_single_window, update_window, update_frame_1)
10226 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10227 (duration_to_sec_usec): Remove; no longer needed.
10229 * editfns.c (time_overflow): Now extern.
10230 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10231 (float-time, Fformat_time_string, Fcurrent_time_string)
10232 (Fcurrent_time_zone): Accept and generate higher-resolution
10234 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10235 (decode_time_components, lisp_seconds_argument): New functions.
10236 (make_time): Now static.
10237 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10238 Report an error if the time is invalid, rather than having the caller
10241 * fileio.c: Include <stat-time.h>
10242 (Fcopy_file): Copy higher-resolution time stamps.
10243 Prefer to set the time stamp via a file descriptor if that works.
10244 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10245 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10246 (Fvisited_file_modtime, Fset_visited_file_modtime):
10247 Support higher-resolution time stamps.
10249 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10251 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10253 * image.c (prepare_image_for_display, clear_image_cache)
10254 (lookup_image): Port to higer-resolution time stamps.
10256 * keyboard.c (start_polling, bind_polling_period):
10257 Check for time stamp overflow.
10258 (read_char, kbd_buffer_get_event, timer_start_idle)
10259 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10260 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10261 Port to higher-resolution time stamps. Do not assume time_t is signed.
10262 (decode_timer): New function. Timers are now vectors of length 9,
10263 not 8, to accommodate the picosecond component.
10264 (timer_check_2): Use it.
10266 * nsterm.m (select_timeout, timeval_subtract): Remove.
10267 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10268 as they're a bit more accurate and handle overflow better.
10269 (ns_select): Change prototype to be compatible with pselect.
10270 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10271 * nsterm.h (ns_select): Adjust prototype.
10273 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10274 us-resolution time stamps.
10275 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10277 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10279 * lisp.h (time_overflow): New decl.
10280 (wait_reading_process_output): First arg is now intmax_t, not int,
10281 to accommodate larger waits.
10283 * process.h (struct Lisp_Process.read_output_delay):
10284 Now counts nanoseconds, not microseconds.
10285 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10287 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10288 (wait_reading_process_output):
10289 Port to ns-resolution time stamps.
10290 (Faccept_process_output, wait_reading_process_output):
10291 Check for time stamp overflow. Do not assume time_t is signed.
10292 (select_wrapper): Remove; we now use pselect.
10293 (Fprocess_attributes): Now generates ns-resolution time stamps.
10295 * sysdep.c: Include utimens.h. Don't include utime.h
10296 or worry about struct utimbuf; gnulib does that for us now.
10297 (gettimeofday): Remove; gnulib provides a substitute.
10298 (make_timeval): New function.
10299 (set_file_times): Now sets ns-resolution time stamps.
10300 New arg FD; all uses changed.
10301 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10302 (system_process_attributes):
10303 Now returns ns-resolution time stamp. All uses changed.
10304 Check for time stamp overflow.
10306 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10307 provides a substitute now.
10309 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10310 since it guarantees struct timespec.
10311 (EMACS_TIME): Now struct timespec, so that we can support
10312 ns-resolution time stamps.
10313 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10314 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10315 (EMACS_USECS): Remove.
10316 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10317 so multiply the arg by 1000 before storing it.
10318 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10320 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10321 Port to ns-resolution time stamps.
10322 (EMACS_TIME_NEG_P): Remove; replaced by....
10323 (EMACS_TIME_SIGN): New macro.
10324 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10325 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10326 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10327 (make_timeval, make_lisp_time, decode_time_components): New decls.
10328 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10329 that it mishandled time_t overflow. You can't compare by subtracting!
10330 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10331 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10333 * term.c: Include <sys/time.h>.
10334 (timeval_to_Time): New function, for proper overflow wraparound.
10335 (term_mouse_position, term_mouse_click): Use it.
10337 * undo.c (record_first_change): Support higher-resolution time stamps
10338 in the undo buffer.
10339 (Fprimitive_undo): Use them when restoring time stamps.
10341 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10342 (w32_get_internal_run_time):
10343 Port to higher-resolution Emacs time stamps.
10344 (ltime): Now accepts single 64-bit integer, as that's more convenient
10347 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10349 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10350 for compatibility with pselect. Support ns-resolution time stamps.
10352 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10354 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10355 Check for time stamp overflow, and support ns-resolution time stamps.
10357 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10358 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10359 (timeval_subtract): Remove; no longer needed.
10360 (XTflash, XTring_bell, x_wait_for_event):
10361 Port to ns-resolution time stamps. Don't assume time_t is signed.
10363 2012-06-22 Chong Yidong <cyd@gnu.org>
10365 * xdisp.c (x_consider_frame_title): Revert last change.
10367 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10369 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10370 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10371 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10372 staticidx goes up to 1597 out of 1600 = 0x640.)
10374 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10376 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10377 Otherwise, the umask might be mistakenly 0 while handling input signals.
10379 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10381 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10387 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10388 access to `contents' member of Lisp_Vector objects with AREF and ASET
10391 2012-06-19 Chong Yidong <cyd@gnu.org>
10393 * frame.c (delete_frame): When selecting a frame on a different
10394 text terminal, do not alter the terminal's top-frame.
10396 * xdisp.c (format_mode_line_unwind_data): Record the target
10397 frame's selected window and its terminal's top-frame.
10398 (unwind_format_mode_line): Restore them.
10399 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10401 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10402 since tty frames can be explicitly named.
10403 (prepare_menu_bars): Likewise.
10405 * term.c (Ftty_top_frame): New function.
10407 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10409 Port byte-code-meter to modern targets.
10410 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10411 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10412 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10413 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10414 (METER_1, METER_2): Simplify.
10416 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10418 * data.c (Fdefalias): Return `symbol' (bug#11686).
10420 2012-06-18 Martin Rudalics <rudalics@gmx.at>

10849 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10850 Convert pctcpu and pctmem to Lisp float properly.

10868 change its type from Lisp_Object to bitfield.
10869 Change type of 'force_start', 'optional_new_start',

10875 Pacify gcc -Wdouble-precision when using Xaw.
10876 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10877 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10878 Use 'float' consistently, rather than 'float' in most places
10879 and 'double' in a couple of places.
10881 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10883 * xdisp.c (handle_stop): Detect whether we have overlay strings
10884 loaded by testing it->current.overlay_string_index to be
10885 non-negative, instead of checking whether n_overlay_strings is
10886 positive. (Bug#11587)
10888 2012-05-31 Chong Yidong <cyd@gnu.org>
10890 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10892 * doc.c (Fsubstitute_command_keys): Doc fix.
10894 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10896 * search.c (search_buffer): Remove calls to
10897 r_alloc_inhibit_buffer_relocation, as it is now called by
10898 maybe_unify_char, which was the cause of relocation of buffer text
10901 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10903 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10904 for the duration of call to load_charset, to avoid problems with
10905 callers of maybe_unify_char that access buffer text through C
10908 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10909 decrement the inhibition flag, instead of just setting or
10912 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10914 Remove obsolete '#define static' cruft.
10915 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10916 This #undef was "temporary" in 2000; it is no longer needed
10917 now that '#define static' has gone away.
10918 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10919 (gray_bitmap_bits): Remove; no longer needed.
10920 All uses replaced with definiens.
10921 * xterm.c: Include "bitmaps/gray.xbm".
10923 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10925 Clean up __executable_start, monstartup when --enable-profiling.
10926 The following changes affect the code only when profiling.
10927 * dispnew.c (__executable_start): Rename from safe_bcopy.
10928 Define only on platforms that need it.
10929 * emacs.c: Include <sys/gmon.h> when profiling.
10930 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10931 (__executable_start): Remove decl, since lisp.h does it now.
10932 (safe_bcopy): Remove decl; no longer has that name.
10933 (main): Coalesce #if into single bit of code, for simplicity.
10934 Cast pointers to uintptr_t, since standard libraries want integers
10936 * lisp.h (__executable_start): New decl.
10938 2012-05-31 Glenn Morris <rgm@gnu.org>
10940 * image.c (Fimagemagick_types): Doc fix.
10942 2012-05-30 Jim Meyering <meyering@redhat.com>
10944 * callproc.c (Fcall_process_region): Include directory component
10945 in mkstemp error message (Bug#11586).
10947 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10949 * alloc.c, lisp.h (make_pure_vector): Now static.
10951 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10953 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10954 Move to byte-run.el.

10956 * data.c (Fdefalias): Purify definition, except for keymaps.
10957 (Qdefun): Move from eval.c.
10958 * lisp.h (Qdefun): Remove.
10959 * lread.c (read1): Tiny simplification.
10961 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10963 Do not create empty overlays with the evaporate property (Bug#9642).
10964 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10965 Bug#9642, but explicitly check that the buffer the overlay would
10966 be moved to is live and rearrange lines to make sure that errors
10967 will not put the overlay in an inconsistent state.
10968 (Fdelete_overlay): Cosmetics.
10970 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10972 * w32term.c (my_bring_window_to_top): New function.
10973 (x_raise_frame): Use handle returned by DeferWindowPos, which
10974 could be different from the original one.
10975 Call my_bring_window_to_top instead of my_set_foreground_window.
10978 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10979 by calling BringWindowToTop.

10984 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10986 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10987 This avoids undefined behavior that might cause the eassert
10988 to not catch an out-of-range value.
10990 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10992 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10993 Update dependencies.
10995 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10997 * bidi.c (bidi_mirror_char): Fix last change.
10999 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11001 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11002 when referring to sectname field in printf format.
11004 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11006 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11007 Only r_alloc_inhibit_buffer_relocation needed to be added;
11008 the others were already declared.
11010 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11011 before checking whether it's out of range. Put the check inside
11013 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11015 2012-05-27 Ken Brown <kbrown@cornell.edu>
11017 * callproc.c (Fcall_process): Restore a line that was accidentally
11018 commented out in the 2011-02-13 change (bug#11547).
11020 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11022 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11023 defined on ralloc.c.
11025 * buffer.c [REL_ALLOC]: Remove prototypes of
11026 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11027 they are now on lisp.h.
11029 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11031 * search.c (search_buffer): Use it to inhibit relocation of buffer
11032 text while re_search_2 is doing its job, because re_search_2 is
11033 passed C pointers to buffer text. (Bug#11519)
11035 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11036 Update value to 24.
11038 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11039 state after an additional call to move_it_in_display_line_to, keep
11040 the values of it->max_ascent and it->max_descent found for the
11042 (pos_visible_p): Revert the comparison against bottom_y to what it
11043 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11046 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11048 Fix coding-related core dumps with gcc -ftrapv.
11049 The code was computing A - B, where A and B are pointers, and B is
11050 random garbage. This can lead to core dumps on platforms that
11051 have special pointer registers, and it also leads to core dumps on
11052 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11053 A - B only when B is initialized properly.
11054 * coding.c (coding_set_source, coding_set_destination): Return void.
11055 (coding_change_source, coding_change_destinations): New functions,
11056 with the old behaviors of coding_set_source and coding_set_destination.
11057 All callers that need an offset changed to use these new functions.
11059 2012-05-26 Glenn Morris <rgm@gnu.org>
11061 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11063 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11065 Extend mouse support on W32 text-mode console.
11066 * xdisp.c (draw_row_with_mouse_face):
11067 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11069 * w32console.c: Include window.h.
11070 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11072 (initialize_w32_display): Initialize mouse-highlight data.
11074 * w32inevt.c: Include termchar.h and window.h.
11075 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11076 moves, call note_mouse_highlight. If help_echo changed, call
11077 gen_help_event to produce help-echo message in the echo area.
11078 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11081 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11083 * lread.c (read1): Simplify slightly to avoid an overflow warning
11084 with GCC 4.7.0 on x86-64.
11086 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11088 * bidi.c (bidi_mirror_char): Revert last change: an int is
11089 definitely wide enough here.
11091 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11093 Fix integer width and related bugs (Bug#9874).
11094 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11095 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11096 (string_bytes, check_sblock, allocate_string_data):
11097 (compact_small_strings, Fmake_bool_vector, make_string)
11098 (make_unibyte_string, make_multibyte_string)
11099 (make_string_from_bytes, make_specified_string)
11100 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11101 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11103 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11104 (allocate_pseudovector):
11105 Use int, not EMACS_INT, where int is wide enough.
11106 (inhibit_garbage_collection, Fgarbage_collect):
11107 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11108 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11109 int might not be wide enough.
11110 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11111 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11112 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11113 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11114 (bidi_level_of_next_char, bidi_move_to_visually_next):
11115 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11116 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11117 (Fkill_buffer, Fset_buffer_major_mode)
11118 (advance_to_char_boundary, Fbuffer_swap_text)
11119 (Fset_buffer_multibyte, overlays_at, overlays_in)
11120 (overlay_touches_p, struct sortvec, record_overlay_string)
11121 (overlay_strings, recenter_overlay_lists)
11122 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11123 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11124 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11125 (Foverlay_recenter, last_overlay_modification_hooks_used)
11126 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11127 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11128 (validate_region): Omit unnecessary test for b <= e,
11129 since that's guaranteed by the previous test.
11130 (adjust_overlays_for_delete): Avoid pos + length overflow.
11131 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11132 (report_overlay_modification):
11133 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11134 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11135 Omit pointer cast, which isn't needed anyway, and doesn't work
11136 after the EMACS_INT -> ptrdiff_t change.
11137 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11138 * buffer.h: Adjust decls to match defn changes elsewhere.
11139 (struct buffer_text, struct buffer):
11140 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11141 Use EMACS_INT, not int, where int might not be wide enough.
11142 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11143 not int, to avoid needless 32-bit limit on 64-bit hosts.
11144 (exec_byte_code): Use tighter memory-full test, one that checks
11145 for alloca overflow. Don't compute the address of the object just
11146 before an array, as that's not portable. Use EMACS_INT, not
11147 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11148 * callint.c (Fcall_interactively):
11149 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11150 * callproc.c (call_process_kill, Fcall_process):
11151 Don't assume pid_t fits into an Emacs fixnum.
11152 (call_process_cleanup, Fcall_process, child_setup):
11153 Don't assume pid_t fits into int.
11154 (call_process_cleanup, Fcall_process, delete_temp_file)
11155 (Fcall_process_region):
11156 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11157 (Fcall_process): Simplify handling of volatile integers.
11158 Use int, not EMACS_INT, where int will do.
11159 * casefiddle.c (casify_object, casify_region, operate_on_word)
11160 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11161 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11162 (casify_object): Avoid integer overflow when overallocating buffer.
11163 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11164 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11165 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11166 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11167 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11168 integers are now checked earlier. All uses replaced with XINT.
11170 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11171 For CCL_MapSingle, check that content and value are in int range.
11172 (ccl_driver, Fregister_code_conversion_map):
11173 Check that Vcode_version_map_vector is a vector.
11174 (resolve_symbol_ccl_program): Check that vector header is in range.
11175 Always copy the vector, so that we can check its contents reliably
11176 now rather than having to recheck each instruction as it's being
11177 executed. Check that vector words fit in 'int'.
11178 (ccl_get_compiled_code, Fregister_ccl_program)
11179 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11180 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11181 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11182 contents are in range.
11183 (Fccl_execute_on_string): Check that status is in range.
11184 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11185 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11186 Accept and return EMACS_INT, not int, because callers can pass values
11187 out of 'int' range.
11188 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11189 (multibyte_chars_in_text, parse_str_as_multibyte)

11191 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11192 (string_escape_byte8, Fget_byte):
11193 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11194 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11195 avoid mishandling large integers.
11196 * character.h: Adjust decls to match defn changes elsewhere.
11197 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11198 (Ffind_charset_region):
11199 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11200 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11201 (load_charset_map_from_vector, Fdefine_charset_internal):
11202 Don't assume fixnum fits in int.
11203 (load_charset_map_from_vector, Fmap_charset_chars):
11204 Remove now-unnecessary CHECK_NATNUMs.
11205 (Fdefine_charset_internal): Check ranges here, more carefully.
11206 Don't rely on undefined behavior with signed left shift overflow.
11207 Don't assume unsigned int fits into fixnum, or that fixnum fits
11208 into unsigned int. Don't require max_code to be a valid fixnum;
11209 that's not true for gb10830 4-byte on a 32-bit host. Allow
11210 invalid_code to be a cons, for the same reason. Require code_offset
11211 to be a character. Avoid int overflow if max_char is close
11213 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11214 this is intended anyway and avoids some undefined behavior.
11215 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11216 INDEX_TO_CODE_POINT, as that's what it expects.
11217 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11218 * charset.h (DECODE_CHAR): Return int, not unsigned;
11219 this is what was intended anyway, and it avoids undefined behavior.
11220 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11221 integer-overflow issues.
11222 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11223 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11224 where the argument is EMACS_INT, and this behavior is not intended.
11225 * chartab.c (Fmake_char_table, Fset_char_table_range)
11226 (uniprop_get_decoder, uniprop_get_encoder):
11227 Don't assume fixnum fits in int.
11228 * cmds.c (move_point): New function, that does the gist of
11229 Fforward_char and Fbackward_char, but does so while checking
11230 for integer overflow more accurately.
11231 (Fforward_char, Fbackward_char): Use it.
11232 (Fforward_line, Fend_of_line, internal_self_insert)
11233 (internal_self_insert):
11234 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11235 Fix a FIXME, by checking for integer overflow when calculating
11236 target_clm and actual_clm.
11237 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

11258 (Fdefine_coding_system_internal)
11259 (coding_set_source, coding_set_destination):

11261 (setup_iso_safe_charsets, consume_chars, Funencodable_char_position)
11262 (Fdefine_coding_system_internal):
11263 Don't assume fixnums fit in int.

11266 (Funencodable_char_position, Fcheck_coding_systems_region)
11267 (get_translation, handle_composition_annotation, consume_chars):
11268 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

11949 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11951 Assume C89 or later.
11952 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11953 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11955 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
11956 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11957 * textprop.c, tparam.c (NULL): Remove.
11958 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11959 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11960 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11961 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11962 * xterm.c (input_signal_count): Assume volatile works.
11964 2012-05-21 Ken Brown <kbrown@cornell.edu>
11966 * xgselect.c (xg_select): Fix first argument in call to 'select'
11969 2012-05-20 Ken Brown <kbrown@cornell.edu>
11971 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11972 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11974 2012-05-19 Ken Brown <kbrown@cornell.edu>
11976 * xfns.c (x_in_use): Remove `static' qualifier.
11977 * xterm.h (x_in_use): Declare.
11978 * xgselect.c: Include xterm.h.
11979 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11980 and `display_arg' (bug#9754).
11982 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11984 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11986 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11987 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11989 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11991 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11993 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11994 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11996 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11997 reference to image_cache->refcount.
11998 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12000 2012-05-17 Juri Linkov <juri@jurta.org>
12002 * search.c (Fword_search_regexp, Fword_search_backward)
12003 (Fword_search_forward, Fword_search_backward_lax)
12004 (Fword_search_forward_lax): Move functions to isearch.el
12005 (bug#10145, bug#11381).
12007 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12009 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12011 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12013 * lread.c (init_obarray): Declare Qt and Qnil as special.
12015 2012-05-14 Glenn Morris <rgm@gnu.org>
12017 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12018 Put "libexec" before "bin", for the sake of init_callproc_1.
12020 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12022 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12024 * unexaix.c: Port to more-recent AIX compilers.
12025 (report_error, report_error_1, make_hdr, copy_sym)
12026 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12027 Make arguments const char *, not char *, to avoid violations of C
12028 standard and to fix some AIX warnings reported by Gilles Pion.
12030 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12032 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12033 already have overlays loaded.
12034 (handle_single_display_spec): Before returning without displaying
12035 fringe bitmap, synchronize the bidi iterator with the main display
12036 iterator, by calling iterate_out_of_display_property.
12037 (iterate_out_of_display_property): Detect buffer iteration by
12038 testing that it->string is a Lisp string.
12039 (get_next_display_element): When the current object is exhausted,
12040 and there's something on it->stack, call set_iterator_to_next to
12041 proceed with what's on the stack, instead of returning zero.
12042 (set_iterator_to_next): If called at the end of a Lisp string,
12043 proceed to consider_string_end without incrementing string
12044 position. Don't increment display vector index past the end of
12045 the display vector. (Bug#11417)
12046 (pos_visible_p): Don't report a position visible when move_it_to
12047 stopped at the last line of window, which happens to be scanned
12048 backwards by the bidi iteration. (Bug#11464)
12050 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12052 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12053 and right-margin display specs even if the spec is invalid or we
12054 are on a TTY, and thus unable to display on the fringes.
12055 That's because the text with the property will not be displayed anyway,
12056 so we need to signal to the caller that this is a "replacing"
12057 display spec. This fixes display when the spec is invalid or we
12060 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12062 * unexaix.c (make_hdr): Fix typo in prototype.
12063 This bug broke the build on AIX. Problem reported by Gilles Pion.
12065 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12067 * keyboard.c (kbd_buffer_get_event): Read special events also in
12068 batch mode. (Bug#11415)
12070 2012-05-12 Glenn Morris <rgm@gnu.org>
12072 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12074 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12076 * lisp.mk (lisp): Add newcomment.elc.
12078 2012-05-12 Glenn Morris <rgm@gnu.org>
12080 * Makefile.in (MKDIR_P): New, set by configure.
12081 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12083 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12085 Remove unused function hourglass_started.
12086 * dispextern.h (hourglass_started):
12087 * w32fns.c (hourglass_started):
12088 * xdisp.c (hourglass_started): Remove.
12090 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12092 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12093 Update dependencies.
12095 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12097 * xgselect.c (xg_select): Put maxfds+1 into a var.
12098 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12100 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12102 2012-05-10 Dave Abrahams <dave@boostpro.com>
12104 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12105 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12107 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12109 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12110 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12111 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12112 Initialize xd_registered_buses.
12114 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12116 Untag more efficiently if USE_LSB_TAG.
12117 This is based on a proposal by YAMAMOTO Mitsuharu in
12118 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12119 For an admittedly artificial (nth 8000 longlist) benchmark on
12120 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12121 Emacs's overall text size by 1%.
12122 * lisp.h (XUNTAG): New macro.
12123 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12124 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12125 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12126 * eval.c (Fautoload):
12127 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12128 * frame.h (XFRAME): Use XUNTAG.
12130 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12131 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12132 Remove unportable assumptions about print widths of types like
12134 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12135 intptr_t when converting between pointer and integer, to avoid GCC
12136 warnings about wrong width.
12138 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12140 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12141 stack for each reader_thread, instead of defaulting to 8MB
12142 determined by the linker. This avoids failures in creating
12143 subprocesses on Windows 7, see the discussion in this thread:
12144 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12146 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12148 Fix up display of the *Minibuf-0* buffer in the mini window.
12149 * keyboard.c (read_char): Don't clear the echo area if there's no
12151 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12152 contents of *Minibuf-0*) if there's no message displayed in its stead.
12154 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12156 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12159 2012-05-06 Chong Yidong <cyd@gnu.org>
12161 * lisp.mk (lisp): Update.
12163 2012-05-05 Jim Meyering <meyering@redhat.com>
12165 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12167 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12169 * data.c (PUT_ERROR): New macro.
12170 (syms_of_data): Use it. Add new error type `user-error'.
12171 * undo.c (user_error): New function.
12172 (Fprimitive_undo): Use it.
12173 * print.c (print_error_message): Adjust print style for `user-error'.
12174 * keyboard.c (user_error): New function.
12175 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12177 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12179 Do not limit current-time-string to years 1000..9999.
12180 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12181 (Fcurrent_time_string): Support any year that is supported by the
12182 underlying localtime representation. Don't use asctime, as it
12183 has undefined behavior for years outside the range -999..9999.
12185 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12187 Fix race conditions involving setenv, gmtime, localtime, asctime.
12188 Without this fix, interrupts could mess up code that uses these
12189 nonreentrant functions, since setting TZ invalidates existing
12190 tm_zone or tzname values, and since most of these functions return
12191 pointers to static storage.
12192 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12193 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12194 Grow the critical sections to include not just invoking
12195 localtime/gmtime, but also accessing these functions' results
12196 including their tm_zone values if any, and any related TZ setting.
12197 (format_time_string): Last arg is now struct tm *, not struct tm **,
12198 so that the struct tm is saved in the critical section.
12199 All callers changed. Simplify allocation of initial buffer, partly
12200 motivated by the fact that memory allocation needs to be outside
12201 the critical section.
12203 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12205 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12206 with RESET_INTERVAL.
12208 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12209 Remove duplicated buffer name initialization.
12211 2012-05-02 Jim Meyering <jim@meyering.net>
12213 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12215 * xfns.c (x_window): Use xstrdup (Bug#11375).
12217 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12219 * xdisp.c (pos_visible_p): If already at a newline from the
12220 display string before the 'while' loop, don't walk back the glyphs
12221 from it3.glyph_row. Solves assertion violation when the display
12222 string begins with a newline (egg.el). (Bug#11367)
12224 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12226 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12229 2012-05-01 Glenn Morris <rgm@gnu.org>
12231 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12232 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12233 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12234 All were removed before 23.1.
12236 * dispnew.c: Remove HAVE_LIBNCURSES test;
12237 it is always true on relevant platforms.
12239 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12240 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12242 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12244 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12246 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12247 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12250 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12252 Do not avoid creating empty evaporating overlays (Bug#9642).
12253 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12254 That is, do not delete an evaporating overlay if it becomes
12255 empty after its bounds are adjusted to fit within its buffer.
12256 This fix caused other problems, and I'm reverting it until we get
12257 to the bottom of them.
12259 2012-04-27 Chong Yidong <cyd@gnu.org>
12261 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12263 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12265 * xdisp.c (pos_visible_p): If the window start position is beyond
12266 ZV, start the display from buffer beginning. Prevents assertion
12267 violation in init_iterator when the minibuffer window is scrolled
12268 via the scroll bar.
12270 * window.c (window_scroll_pixel_based): Likewise.
12272 2012-04-27 Chong Yidong <cyd@gnu.org>
12274 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12276 2012-04-27 Glenn Morris <rgm@gnu.org>
12278 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12279 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12281 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12283 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12284 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12286 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12288 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12289 display element, check also the underlying string or buffer
12290 character. (Bug#11341)
12292 * w32menu.c: Include w32heap.h.
12293 (add_menu_item): If the call to AppendMenuW (via
12294 unicode_append_menu) fails, disable Unicode menus only if we are
12295 running on Windows 9X/Me.
12297 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12299 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12300 (xgetint): Add missing shift for LSB tags.
12302 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12304 * keyboard.c (read_char): Don't wipe echo area for select window
12305 events: These might get delayed via `mouse-autoselect-window'
12308 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12310 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12311 manipulation of :loaded-from data.
12313 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12315 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12316 now a cons (bug#11311).
12318 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12320 Do not create empty overlays with the evaporate property (Bug#9642).
12321 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12322 if it becomes empty after its bounds are adjusted to fit within
12323 its buffer. Without this fix, in a nonempty buffer (let ((o
12324 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12325 yields an empty overlay that has the evaporate property, which is
12326 not supposed to happen.
12328 Fix minor GTK3 problems found by static checking.
12329 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12330 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12331 (struct _EmacsFixedClass, emacs_fixed_get_type):
12332 Move decls here from emacsgtkfixed.h, since they needn't be public.
12333 (emacs_fixed_get_type): Now static.
12334 (emacs_fixed_class_init): Omit unused local.
12335 (emacs_fixed_child_type): Remove; unused.
12336 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12337 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12338 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12339 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12340 (EMACS_FIXED_GET_CLASS): Remove; unused.
12341 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12343 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12344 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12346 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12348 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12349 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12350 (__malloc_size_t, __malloc_ptrdiff_t):
12351 Remove. All uses removed, replaced by the definiens if needed,
12352 since we can assume C89 or better now.
12353 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12361 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12362 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12363 Define using prototypes, not old style.
12364 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
12365 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
12366 (align): Don't assume that signed integer overflow wraps around.
12367 Omit unused local var.
12368 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
12369 (_free_internal_nolock, memalign, mallochook, reallochook):
12370 Omit no-longer-needed casts.
12371 (valloc): Use getpagesize, not __getpagesize.
12372 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
12373 (struct hdr): The 'magic' member is now size_t, not unsigned long.
12375 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
12377 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
12379 Move functions from C to Lisp. Make non-blocking method calls
12380 the default. Implement further D-Bus standard interfaces.
12382 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

12441 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12443 * sysdep.c [__FreeBSD__]: Minor cleanups.
12444 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12445 Use Emacs indenting style more consistently. Avoid some casts.

12464 * print.c (print_preprocess): Only check print_depth if print-circle
12466 (print_object): Check for cycles even when print-circle is nil and

12471 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12472 set the status to "failed" and ensure that sentinel is run.
12474 2012-04-20 Glenn Morris <rgm@gnu.org>
12476 * process.c (Fset_process_inherit_coding_system_flag)
12477 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12529 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12530 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12531 (NEED_MEM_INSERT): New macro.
12532 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12533 Remove one incorrect comment and fix another.

12569 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12570 * s/netbsd.h, s/sol2-6.h:
12571 Remove definition of GC_MARK_STACK, since the default now works.
12572 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12600 2012-04-11 Daniel Colascione <dancol@dancol.org>
12602 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12603 against is gone. It's better to use vfork now so that when Cygwin
12604 gains a new, working vfork, we use it automatically (bug#10398).
12606 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12627 being loaded (bug#10424).
12629 2012-04-09 Glenn Morris <rgm@gnu.org>
12631 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

12659 * minibuf.c (Fread_variable): Callers changed.
12661 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12663 * xdisp.c (set_cursor_from_row): If the display string appears in
12664 the buffer at position that is closer to point than the position
12665 after the display string, display the cursor on the first glyph of
12666 the display string. Fixes cursor display when a 'display' text
12667 property immediately follows invisible text. (Bug#11094)
12669 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12671 composite.c: use 'double' consistently
12672 * composite.c (get_composition_id): Use 'double' consistently
12673 instead of converting 'float' to 'double' and vice versa; this is
12674 easier to understand and avoids a GCC warning.
12676 2012-04-09 Glenn Morris <rgm@gnu.org>
12678 * Makefile.in: Generate leim-list with bootstrap-emacs, in

12723 [!WINDOWSNT]: New macros.
12724 (init_libxml2_functions, libxml2_loaded_p): New functions.

12728 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12730 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12731 Call init_libxml2_functions before calling libxml2 functions.

12742 * indent.c (Fvertical_motion): If there is a display string at
12743 point, use it.vpos to compute how many lines to backtrack after
12744 move_it_to point. (Bug#11133)
12746 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12748 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12749 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12750 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12751 macros related to unification of CJK characters. For the details,
12752 see the discussion following the message here:
12753 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

12769 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12771 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12772 position we get to after a call to move_it_to fails the
12773 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12774 only if we wind up in a string from display property. (Bug#11063)
12776 * window.c (Fdelete_other_windows_internal): Invalidate the row
12777 and column information about mouse highlight, so that redisplay
12778 restores it after reallocating the glyph matrices. (Bug#7464)
12780 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12781 string comes from a `display' text property, use the buffer
12782 position of that property as if we actually saw that position in
12784 (move_it_by_lines): Remove the assertion that
12785 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12786 violated when there's a before-string at the beginning of a line.

12794 extending the face to the end of the line.
12795 (display_line): Call extend_face_to_end_of_line when the default
12796 face was remapped. (Bug#11068)

12833 * s/ms-w32.h (tzname): Include time.h before redirecting to
12834 _tzname. Fixes the MSVC build. (Bug#9960)
12836 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12838 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12841 * xterm.c (XTread_socket): Only modify handling_signal if
12842 !SYNC_INPUT. (Bug#11080)
12844 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12846 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12847 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12848 when fetching a multibyte character consumes more bytes than
12849 CHAR_BYTES returns, due to unification of CJK characters in
12850 string_char. (Bug#11073)
12852 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12854 * process.c (wait_reading_process_output): Handle pty disconnect
12855 by refraining from sending oneself a SIGCHLD (bug#10933).

12861 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12862 Mark string as coming from a prefix property.
12863 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12864 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12866 2012-03-21 Chong Yidong <cyd@gnu.org>
12868 * xfaces.c (Vface_remapping_alist): Doc fix.
12870 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12872 * w32proc.c (Fw32_set_console_codepage)
12873 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12876 2012-03-20 Chong Yidong <cyd@gnu.org>
12878 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12879 to reflect default non-nil value of redisplay-dont-pause.
12881 2012-03-19 Kenichi Handa <handa@m17n.org>
12883 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12884 it fit in a valid range (Bug#11003).
12886 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12888 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12889 that is not from display property, accept the row as a "cursor
12890 row" if one of the string's character has a non-nil `cursor'
12891 property. Fixes cursor positioning when there are newlines in
12892 overlay strings, e.g. in icomplete.el. (Bug#11035)
12894 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12896 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12898 2012-03-12 Chong Yidong <cyd@gnu.org>
12900 * eval.c (inhibit_lisp_code): Rename from
12901 inhibit_window_configuration_change_hook; move from window.c.
12903 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12904 * window.c (run_window_configuration_change_hook)
12905 (syms_of_window): Callers changed.

12911 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12913 2012-03-10 Chong Yidong <cyd@gnu.org>
12915 * frame.c (other_visible_frames): Don't assume the selected frame
12916 is visible (Bug#10955).
12918 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12920 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12924 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12925 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12928 2012-03-03 Glenn Morris <rgm@gnu.org>
12930 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12932 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12934 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12935 position past the first glyph_row that ends at ZV. (Bug#10902)
12936 (redisplay_window, next_element_from_string): Fix typos in
12938 (redisplay_window): Pass to move_it_vertically the margin in
12939 pixels, not in screen lines.
12941 2012-03-02 Glenn Morris <rgm@gnu.org>
12943 * buffer.c (buffer-list-update-hook): Doc fix.
12945 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12947 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12948 push_it before setting up the iterator for the first overlay
12949 string, even if we have an empty string loaded.
12950 (next_overlay_string): If there's an empty string on the iterator
12951 stack, pop the stack. (Bug#10903)
12953 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12955 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12956 Suggested by Stefan Monnier in
12957 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12958 * alloc.c (widen_to_Lisp_Object): New static function.
12959 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12960 and widening them to Lisp_Objects. This would work even if
12961 USE_LSB_TAG is defined and wide integers are used, which might
12962 happen in a future version of Emacs.
12964 2012-02-25 Chong Yidong <cyd@gnu.org>
12966 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12969 * xselect.c (Fx_selection_exists_p): Doc fix.
12970 (x_clipboard_manager_save_all): Print an informative message
12971 before saving to clipboard manager.
12973 2012-02-24 Chong Yidong <cyd@gnu.org>
12975 * keyboard.c (process_special_events): Handle all X selection
12976 requests in kbd_buffer, not just the next one (Bug#8869).
12978 2012-02-23 Chong Yidong <cyd@gnu.org>
12980 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12981 call when setting menu-bar-lines and tool-bar-lines parameters.
12982 (unwind_create_frame_1): New helper function.
12984 * window.c (inhibit_window_configuration_change_hook): New var.
12985 (run_window_configuration_change_hook): Obey it.
12986 (syms_of_window): Initialize it.
12988 2012-02-22 Chong Yidong <cyd@gnu.org>
12990 * xterm.c (x_draw_image_relief): Add missing type check for
12991 Vtool_bar_button_margin (Bug#10743).
12993 2012-02-21 Chong Yidong <cyd@gnu.org>
12995 * fileio.c (Vfile_name_handler_alist): Doc fix.
12997 * buffer.c (Fget_file_buffer): Protect against invalid file
12998 handler return value.
13000 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13002 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13003 when computing $valmask.
13005 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13006 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13007 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13008 It's useless in that case, and it can cause problems on hosts
13009 that allocate halves of EMACS_INT values separately.
13010 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13011 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13012 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13013 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13014 it avoids undefined behavior on hosts where shifting right by more
13015 than the word width has undefined behavior.
13017 2012-02-19 Chong Yidong <cyd@gnu.org>
13019 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13020 (Funhandled_file_name_directory, Ffile_name_as_directory)
13021 (Fdirectory_file_name, Fexpand_file_name)
13022 (Fsubstitute_in_file_name): Protect against invalid file handler
13023 return values (Bug#10845).
13025 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13027 * .gdbinit (pitx): Fix incorrect references to fields of the

13037 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13039 2012-02-15 Chong Yidong <cyd@gnu.org>
13041 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13042 marked as special. Also, starting docstrings with * is obsolete.
13044 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13046 * gnutls.c (emacs_gnutls_write): Fix last change.

13055 * keymap.c (Fsingle_key_description): Handle char ranges.
13057 2012-02-12 Chong Yidong <cyd@gnu.org>
13059 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13060 as that creates a dangerous corner case.
13062 * window.c (Fdelete_window_internal): Invalidate the mouse
13063 highlight (Bug#9904).
13065 2012-02-12 Glenn Morris <rgm@gnu.org>

13068 (Fx_get_selection_internal, Fx_disown_selection_internal)
13069 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13070 * nsselect.m (Fx_own_selection_internal)
13071 (Fx_disown_selection_internal, Fx_selection_exists_p)
13072 (Fx_selection_owner_p, Fx_get_selection_internal):
13073 Sync docs and argument specs with the xselect.c versions.
13075 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13077 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13079 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13081 * w32select.c (Fx_selection_exists_p): Sync doc string and
13082 argument list with xselect.c. (Bug#10783)

13095 2012-02-07 Chong Yidong <cyd@gnu.org>
13097 * buffer.c (Fbuffer_local_variables)
13098 (buffer_lisp_local_variables): Handle unbound vars correctly;
13099 don't let Qunbound leak into Lisp.
13101 2012-02-07 Glenn Morris <rgm@gnu.org>
13103 * image.c (Fimagemagick_types): Doc fix.
13105 * image.c (imagemagick-render-type): Change it from a lisp object
13106 to an integer. Move the doc here from the lisp manual.
13107 Treat all values not equal to 0 the same.

13119 2012-02-04 Chong Yidong <cyd@gnu.org>
13121 * nsterm.m: Declare a global (Bug#10694).
13123 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13125 * w32.c (get_emacs_configuration_options):
13126 Include --enable-checking, if specified, in the return value.
13128 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13130 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13131 after rounding frame sizes. (Bug#9723)

13135 * keyboard.c (adjust_point_for_property): Don't position point
13136 before BEGV. (Bug#10696)
13138 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13140 Handle overflow when computing char display width (Bug#9496).
13141 * character.c (char_width): Return EMACS_INT, not int.
13142 (char_width, c_string_width): Check for overflow when
13143 computing the width; this is possible now that individual
13144 characters can have unbounded width. Problem introduced
13145 by merge from Emacs 23 on 2012-01-19.
13147 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13149 * dbusbind.c (Fdbus_register_method): Mention the return value
13150 :ignore in the docstring.

13162 2012-02-02 Kenichi Handa <handa@m17n.org>
13164 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13165 0, do not call append_composite_glyph.
13167 2012-02-02 Kenichi Handa <handa@m17n.org>
13169 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13171 (x_produce_glyphs): If the component of a composition is a null
13172 string, set it->pixel_width to 1 to avoid zero-width glyph.
13174 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13176 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13177 first 2 arguments are identical. This makes inserting large
13178 output from a subprocess an order of magnitude faster on
13179 MS-Windows, where all sbrk'ed memory is always contiguous.
13181 2012-01-31 Glenn Morris <rgm@gnu.org>
13183 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13219 2012-01-21 Chong Yidong <cyd@gnu.org>
13221 * floatfns.c (Fcopysign): Make the second argument non-optional,
13222 since nil is not allowed anyway.
13224 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13226 * process.c (read_process_output): Use p instead of XPROCESS (proc).

13233 Rewrite doc-strings.
13235 2012-01-19 Kenichi Handa <handa@m17n.org>
13237 * character.c (char_width): New function.
13238 (Fchar_width, c_string_width, lisp_string_width):
13239 Use char_width (Bug#9496).

13261 he end column for display of highlight that ends on a newline
13264 2012-01-11 Glenn Morris <rgm@gnu.org>
13266 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
13267 from load-path also when installation-directory is nil. (Bug#10208)
13269 2012-01-10 Glenn Morris <rgm@gnu.org>
13271 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
13273 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
13274 Update template values to be closer to their typical values these days.
13276 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13278 * xdisp.c (rows_from_pos_range): Accept additional argument
13279 DISP_STRING, and accept any glyph in a row whose object is that
13280 string as eligible for mouse highlight. Fixes mouse highlight of
13281 display strings from overlays. (Bug#10464)
13283 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
13285 emacs: fix an auto-save permissions race condition (Bug#10400)
13286 * fileio.c (auto_saving_dir_umask): New static var.
13287 (Fmake_directory_internal): Use it.
13288 (do_auto_save_make_dir): Set it, instead of invoking chmod after
13289 creating the directory. The old code temporarily assigns
13290 too-generous permissions to the directory.
13291 (do_auto_save_eh): Clear it.
13292 (Fdo_auto_save): Catch all errors, not just file errors, so
13293 that the var is always cleared.
13295 2012-01-07 Eli Zaretskii <eliz@gnu.org>
13297 * search.c (scan_buffer): Pass character positions to
13298 know_region_cache, not byte positions. (Bug#6540)
13300 2012-01-07 LynX <_LynX@bk.ru> (tiny change)
13302 * w32.c (sys_rename): Report EXDEV when rename of a directory
13303 fails because the target is on another logical disk. (Bug#10284)

13798 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13799 is set, removing the need for VIRT_ADDRESS_VARIES.
13800 (PURE_P): Use a more-efficient implementation that needs just one
13801 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13802 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13803 to 4 (xorl, subq, cmpq, setbe).
13804 * alloc.c (pure): Always extern now, since that's the
13805 VIRT_ADDR_VARIES behavior.
13806 (PURE_POINTER_P): Use a single comparison, not two, for
13807 consistency with the new puresize.h.
13808 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13809 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13810 Remove VIRT_ADDR_VARIES no longer needed.
13812 2011-11-19 Eli Zaretskii <eliz@gnu.org>
13814 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
13815 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13816 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13817 behave as if the cursor position were at the window margin.
13819 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13820 and the cursor position is out of bounds, behave as if the cursor
13821 position were at the window margin. (Bug#10075)
13823 2011-11-18 Chong Yidong <cyd@gnu.org>
13825 * window.c (Fwindow_combination_limit): Make first argument

13843 hash values of the two rows. (Bug#10035)
13844 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13846 * xdisp.c (row_hash): New function, body extracted from
13847 compute_line_metrics.
13848 (compute_line_metrics): Call row_hash, instead of computing the
13851 * dispnew.c (verify_row_hash): Call row_hash for computing the
13852 hash code of a row, instead of duplicating code from xdisp.c.
13854 * dispextern.h (row_hash): Add prototype.
13856 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13858 * frame.c (delete_frame): Don't delete the terminal when the last

13884 (Fsplit_window_internal, saved_window)
13885 (Fset_window_configuration, save_window_save): Rename all
13886 occurrences of window_nest to window_combination_limit.
13888 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

13892 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13894 * xdisp.c (display_line): Move the call to
13895 highlight_trailing_whitespace before the call to
13896 compute_line_metrics, since the latter needs to see the final
13897 faces of all the glyphs to compute ROW's hash value.
13898 Fixes assertion violations in row_equal_p. (Bug#10035)
13900 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13902 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13903 just return (bug#10044).
13905 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13907 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13908 with user-defined heap size. Bump the default size of the temacs

13910 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13912 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13913 current_matrix and desired_matrix. (Bug#9990)
13914 (verify_row_hash) [XASSERTS]: New function.
13915 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13916 that the hash value of glyph rows is correct.

13945 2011-11-11 Johan Bockgård <bojohan@gnu.org>
13947 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
13948 avoid a crash (bug#9496).
13950 2011-11-09 Chong Yidong <cyd@gnu.org>
13952 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13959 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13961 Avoid some portability problems by eschewing 'extern inline' functions.
13962 The trivial performance wins aren't worth the portability hassles; see
13963 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13965 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13966 (window_box_width, window_box_left, window_box_left_offset)
13967 (window_box_right, window_box_right_offset): Undo previous change,
13968 by removing the "extern"s.
13969 * intervals.c (adjust_intervals_for_insertion)
13970 (adjust_intervals_for_deletion): Undo previous change,
13971 making these static again.
13972 (offset_intervals, temp_set_point_both, temp_set_point)
13973 (copy_intervals_to_string): No longer inline.
13974 * xdisp.c (window_text_bottom_y, window_box_width)
13975 (window_box_height, window_box_left_offset)
13976 (window_box_right_offset, window_box_left, window_box_right)

13998 2011-11-07 Martin Rudalics <rudalics@gmx.at>
14000 * window.h: Declare delete_all_child_windows instead of
14001 delete_all_subwindows.
14002 * window.c (Fwindow_nest, Fset_window_nest)
14003 (Fset_window_new_total, Fset_window_new_normal)
14004 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
14005 (delete_all_subwindows): Rename to delete_all_child_windows.
14006 (Fdelete_other_windows_internal, Fset_window_configuration):
14007 Call delete_all_child_windows instead of delete_all_subwindows.

14011 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
14013 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14014 This is also needed for porting to any host where GC_MARK_STACK is
14015 not GC_MAKE_GCPROS_NOOPS.
14016 (which_symbols): Use it.
14018 2011-11-07 Kenichi Handa <handa@m17n.org>

14031 * xmenu.c (cleanup_widget_value_tree): New function.
14032 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14033 calling free_menubar_widget_value_tree directly (Bug#9830).

14037 Fix some portability problems with 'inline'.
14038 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14039 (window_box_width, window_box_left, window_box_left_offset)
14040 (window_box_right, window_box_right_offset): Declare extern.
14041 Otherwise, these inline functions do not conform to C99 and
14042 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14043 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14044 * intervals.c (adjust_intervals_for_insertion)
14045 (adjust_intervals_for_deletion): Now extern, because otherwise the
14046 extern inline functions 'offset_intervals' couldn't refer to it.
14047 (static_offset_intervals): Remove.
14048 (offset_intervals): Rewrite using the old contents of
14049 static_offset_intervals. The old version didn't conform to C99
14050 because an extern inline function contained a reference to an
14051 identifier with static linkage.
14053 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14055 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14060 * xdisp.c (init_iterator, reseat_to_string): Don't set the
14061 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
14062 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
14063 return Qleft_to_right.

14068 (Fminibuffer_window, Fwindow_buffer, Fwindow_splits)
14069 (Fset_window_splits, Fwindow_nest, Fset_window_nest)
14070 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
14071 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
14072 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
14073 (Fwindow_vscroll): Doc fix.
14074 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14075 argument, since it makes no sense to pass a live window and for
14076 consistency with window-child.

14101 2011-11-05 Jan Djärv <jan.h.d@swipnet.se>
14103 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
14104 (unwind_create_frame): New function (Bug#9943).
14105 (Fx_create_frame): Restructure code to be more similar to the one in
14106 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
14107 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
14108 Move terminal->reference_count++ just before making the frame official
14111 * nsterm.m (x_free_frame_resources): New function.
14112 (x_destroy_window): Move code to x_free_frame_resources.
14114 * xfns.c (unwind_create_frame): Fix comment.
14115 (Fx_create_frame, x_create_tip_frame):

14117 official. Move initialization of image_cache_refcount and
14118 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

14248 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14249 Not clear what it was for, and it causes various bugs. (Bug#9839)
14251 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14253 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14254 possible random value that matches one of those tested as
14255 condition to clear the mouse face.
14257 2011-10-28 Chong Yidong <cyd@gnu.org>
14259 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14261 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14263 * window.c (make_window): Initialize phys_cursor_on_p.
14265 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14267 * lisp.h (struct Lisp_Symbol): Update comments.
14269 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14271 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14273 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14275 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14276 <oslsachem@gmail.com> for helping to debug this.
14278 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14279 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14280 (g_b_init_get_glyph_outline_w): New static variables.
14281 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14282 (GetGlyphOutlineW_Proc): New typedefs.
14283 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14284 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14286 (w32font_open_internal, compute_metrics):
14287 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14288 instead of calling the "wide" APIs directly.
14290 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14292 * w32.h (syms_of_w32font): Add prototype.
14294 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14296 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14297 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14298 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14299 (Fmove_to_window_line): Doc fix.
14301 2011-10-27 Chong Yidong <cyd@gnu.org>
14303 * process.c (make_process): Set gnutls_state to NULL.
14305 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14306 non-NULL, regardless of GNUTLS_INITSTAGE.
14307 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14308 an error. Set process slots as soon as we allocate them.
14310 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14312 2011-10-27 Chong Yidong <cyd@gnu.org>
14314 * gnutls.c (emacs_gnutls_deinit): New function.
14315 Deallocate credentials structures as well as calling gnutls_deinit.
14316 (Fgnutls_deinit, Fgnutls_boot): Use it.
14318 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14319 (deactivate_process): Call emacs_gnutls_deinit.
14321 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14323 * image.c (x_create_x_image_and_pixmap):
14324 * w32.c (sys_rename, w32_delayed_load):
14325 * w32font.c (fill_in_logfont):
14326 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14328 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14330 * w32fns.c (w32_default_color_map): New function,
14331 extracted from Fw32_default_color_map.
14332 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14334 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14336 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14338 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14340 * keyboard.c (test_undefined): New function (bug#9751).
14341 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14343 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14345 * sysdep.c (init_sys_modes): Fix the check for the controlling
14346 terminal (Bug#6649).
14348 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14350 * dispextern.h (struct bidi_it): New member next_en_type.
14352 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14353 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14354 current character, check also for next_en_type being WEAK_EN.
14355 (bidi_resolve_weak): Don't enter the expensive loop if the current
14356 position is before next_en_pos. Record the bidi type of the first
14357 non-ET, non-BN character we find, in addition to its position.
14358 (bidi_level_of_next_char): Invalidate next_en_type when
14359 next_en_pos is over-stepped.
14361 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14363 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14364 * editfns.c: Rewrite current-time-zone so that it invokes
14365 the equivalent of (format-time-string "%Z") to get the time zone name.
14366 This fixes a bug when the time zone name contains characters that
14367 need converting from the system time locale to Emacs internal format.
14368 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14369 that patch fixed format-time-string to do the conversion, but
14370 I forgot to fix current-time-zone.
14371 (format_time_string): New function, containing most of
14372 what Fformat_time_string used to contain.
14373 (Fformat_time_string): Rewrite in terms of format_time_string.
14374 This doesn't change this function's behavior.
14375 (current-time-zone): Rewrite to use format_time_string.
14376 This fixes the bug reported by Michael Schierl in
14377 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14378 Jason Rumney's 2007-06-07 change worked around this bug, but
14380 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14382 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14384 * xdisp.c (start_display): If the character at POS is displayed
14385 via a display vector, reset IT->current.dpvec_index to zero.
14386 (try_window_reusing_current_matrix): If a line ends in a display
14387 vector or the next line starts in a display vector, continue
14388 redrawing the window even though the character position of
14389 start_row was reached.
14392 2011-10-18 Chong Yidong <cyd@gnu.org>
14394 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14395 with nobreak-char-display too.
14397 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14399 Fix part 3 of bug#9771.
14400 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14401 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14402 non-neutral characters if the current character is a paragraph
14403 separator (a.k.a. Newline). This avoids running the same
14404 expensive loop twice, once when we consume the preceding newline
14405 and the other time when the line actually needs to be displayed.
14406 Avoid the loop when we see neutrals on the base embedding level
14407 following a character whose directionality is the same as the
14408 paragraph's. This avoids running the expensive loop when a line
14409 ends in a long sequence of neutrals, like control characters.
14410 Add assertion against STRONG_AL type. Slightly rearrange code
14411 that determines the type of a neutral given the first non-neutral
14413 (bidi_level_of_next_char): Set next_en_pos to zero when
14414 invalidating its info.
14416 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14418 * xdisp.c (push_display_prop): Determine whether to record string
14419 or buffer position by IT->string, not by IT->method. Allow
14420 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14421 (move_it_vertically_backward): Don't look for character position
14422 immediately after the newline when in a continuation line.
14425 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14427 * window.c (coordinates_in_window): Rewrite and delabelize
14428 vertical border check. (Bug#5357) (Bug#9618)
14430 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14432 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14433 errors in XSetWindowBorder (bug#9310).
14435 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14437 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14438 avoid crash when xmalloc overrun checking is enabled.
14440 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14442 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14443 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14444 cursor motion with <left> and <right> arrow keys.
14446 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14447 some callers set that themselves.
14449 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14451 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14452 display string and the previous row comes from the same string and
14453 is empty. (Bug#9739) (Bug#9738)
14455 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14457 * doc.c (get_doc_string): Encode file name (bug#9735).
14459 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14461 * bidi.c (bidi_level_of_next_char):
14462 * xdisp.c (get_visually_first_element): Remove old incorrect
14463 comments regarding the Unicode Line Separator character.
14465 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14467 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14469 * alloc.c (Fgc_status): Do not access beyond zombies array
14470 boundary if nzombies > MAX_ZOMBIES.
14471 * alloc.c (dump_zombies): Add missing format specifier.
14473 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14475 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14476 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14478 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14479 Some packages use them to denote characters with modifiers.
14481 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14483 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14484 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14485 matching a pp-number. Rename parameter var to var1.
14487 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14489 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14491 2011-10-08 Glenn Morris <rgm@gnu.org>
14493 * callint.c (Fcall_interactively): Give a more explicit error for the
14494 'c' case with a non-character input. (Bug#8479)
14496 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14498 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14500 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14501 lines that are hscrolled on the left.
14503 * dispnew.c (buffer_posn_from_coords): Account for a possible
14504 presence of header-line. (Bug#4426)
14506 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14508 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14509 Don't advertise functionality which we discourage or doesn't work.
14511 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14513 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14514 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14515 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14516 this makes Emacs dump core during garbage collection on rare
14517 occasions. sizeof is obviously inferior to offsetof here, so
14518 stick with offsetof.
14519 (GC_POINTER_ALIGNMENT): New macro.
14520 (mark_memory): Omit 3rd (offset) arg; caller changed.
14521 Don't assume EMACS_INT alignment is the same as pointer alignment.
14523 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14525 * keyboard.c (read_key_sequence_remapped): New var.
14526 (read_key_sequence): Compute remapping in the right buffer.
14527 (command_loop_1): Use read_key_sequence's remapping directly.
14529 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14531 * dired.c (file_name_completion): Don't expand file name.
14532 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14533 before checking file name handler.
14535 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14536 they've been requested explicitly (bug#9591).
14538 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14540 * keymap.c (Fsingle_key_description): Use make_specified_string
14541 instead of build_string to build string from push_key_description.
14544 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14546 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14547 This fixes a Y2038 bug on 64-bit hosts.
14548 * buffer.c (reset_buffer):
14549 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14550 (Fclear_buffer_auto_save_failure):
14551 Use 0, not -1, to represent an unset failure time, since time_t
14552 might not be signed.
14554 Remove dependency on glibc malloc internals.
14555 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14556 Move back here from lisp.h, but with their new implementations.
14557 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14558 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14559 * charset.c (charset_table_init): New static var.
14560 (syms_of_charset): Use it instead of xmalloc. This removes a
14561 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14562 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14563 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14564 Move back to alloc.c.
14565 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14566 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14568 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14570 * nsterm.m (windowDidResize): Call x_set_window_size only when
14571 ns_in_resize is true. Otherwise set pixelwidth/height and
14572 call change_frame_size (Bug#9628).
14574 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14576 Port --enable-checking=all to Fedora 14 x86-64.
14577 * charset.c (syms_of_charset): Also account for glibc malloc's
14578 internal overhead when calculating the initial malloc maximum.
14580 Port --enable-checking=all to Fedora 14 x86.
14581 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14583 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14584 (overrun_check_realloc, overrun_check_free):
14585 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14586 That way, xmalloc returns a properly-aligned pointer even if
14587 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14588 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14589 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14590 into account when calculating the initial malloc maximum.
14591 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14592 Move here from alloc.c, so that charset.c can use it too.
14593 Properly align; the old code wasn't right for common 32-bit hosts
14594 when configured with --enable-checking=all.
14595 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14596 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14598 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14600 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14603 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14605 * xdisp.c (compute_display_string_end): If there's no display
14606 string at CHARPOS, return -1.
14608 * bidi.c (bidi_fetch_char): When compute_display_string_end
14609 returns a negative value, treat the character as a normal
14610 character not covered by a display string. (Bug#9624)
14612 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14614 * lread.c (Fread_from_string): Fix typo in docstring.
14616 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14618 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14619 newline, reseat the iterator instead of bidi-iterating there one
14620 character at a time. (Bug#9610)
14621 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14622 TO_CHARPOS if the bidi iterator is at base embedding level.
14624 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14626 * lread.c (readevalloop): Use correct code for NBSP.
14627 (read1): Likewise. (Bug#9608)
14629 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14631 * dbusbind.c (Fdbus_register_signal): When service is not
14632 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14634 2011-09-25 Glenn Morris <rgm@gnu.org>
14636 * buffer.c (truncate-lines): Doc fix.
14638 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14640 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14641 (Fset_window_next_buffers): Doc fix.
14643 2011-09-24 Glenn Morris <rgm@gnu.org>
14645 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14647 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14649 Fix minor problems found by static checking.
14650 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14651 * indent.c (Fvertical_motion): Fix == vs = typo.
14653 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14655 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14656 Default value is now t. Doc fix.
14658 * indent.c (Fvertical_motion): Compute and apply the overshoot
14659 logic when moving up, not only when moving down. Fix the
14660 confusing name and values of the it_overshoot_expected variable;
14661 logic changes accordingly. (Bug#9254) (Bug#9549)
14663 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14664 CHARPOS is covered by a display string which includes newlines.
14665 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14666 is covered by a display string with embedded newlines.
14668 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14670 * dbusbind.c (Fdbus_register_signal): Add match rule to
14671 Vdbus_registered_objects_table. (Bug#9581)
14672 (Fdbus_register_method, Vdbus_registered_objects_table):
14675 2011-09-24 Jim Meyering <meyering@redhat.com>
14677 do not ignore write error for any output size
14678 The previous change was incomplete.
14679 While it makes emacs --batch detect the vast majority of stdout
14680 write failures, errors were still ignored whenever the output size is
14681 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14682 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14683 && echo FAIL: ignored write error
14684 FAIL: ignored write error
14685 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14686 && echo FAIL: ignored write error
14687 FAIL: ignored write error
14688 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14690 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14692 * emacs.c (Fkill_emacs): In noninteractive mode exit
14693 non-successfully if a write error occurred on stdout. (Bug#9574)

14697 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14700 * dispextern.h (struct it): Update the comment documenting what
14703 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14705 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14706 a display string, extend search for cursor position to end of row.
14707 (find_row_edges): If the row ends in a newline from a display
14708 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14709 Handle the case of a display string with multiple newlines.
14710 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14711 non-empty line. Fixes confusing cursor motion with arrow keys at
14712 the beginning of a line that starts with whitespace.
14714 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14716 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14719 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14721 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14722 boolean (Bug#9154).
14724 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14726 * xdisp.c (display_line): Record maximum and minimum buffer
14727 positions even if no glyphs were produced (e.g., by a zero-width
14728 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14729 buffer positions that will be removed from the glyph row because
14731 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14732 column is beyond frame width: don't subtract 1 "pixel" when
14733 computing width of the stretch.
14734 (reseat_at_next_visible_line_start): Undo the change made on
14735 2011-09-17 that saved paragraph information and restored it after
14736 the call to `reseat'. (Bug#9545)
14738 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14740 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14741 and turn window cursor on if cleared (Bug#9415).
14743 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14745 * search.c (boyer_moore): Take unibyte characters from pattern
14746 literally. (Bug#9458)
14748 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14750 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14752 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14754 Fix minor problem found by static checking.
14755 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14756 initialized, to pacify gcc -Wuninitialized.
14758 * fileio.c: Report proper errno when syscall falls.
14759 (Finsert_file_contents): Save and restore errno,
14760 so that report_file_error outputs the correct diagnostic.
14761 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14763 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14765 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14767 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14769 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14770 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14772 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14774 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14775 about the current paragraph and restore it after the call to reseat.
14777 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14778 (bidi_find_paragraph_start): Search back for paragraph beginning
14779 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14780 (bidi_move_to_visually_next): Only trigger paragraph-related
14781 computations when the last character is a newline or at EOB, not
14782 just any NEUTRAL_B. (Bug#9470)
14784 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14785 truncated lines if point is covered by a display string. (Bug#9524)
14787 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14789 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14790 (cons_to_x_long): New function.
14791 (lisp_data_to_selection_data): Use it. Correct the test for
14792 short-versus-long data; it was negated. Break out of vector
14793 loop, for efficiency, when a long datum is discovered.
14795 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14797 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14799 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14801 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14802 GCC PR/17406) by declaring this function with external scope.
14804 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14806 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14807 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14809 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14811 * editfns.c (Fformat): Correctly handle text properties on "%%".
14813 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14815 * xterm.c (x_draw_composite_glyph_string_foreground):

14818 * composite.c (composition_update_it, get_composition_id):
14819 * xdisp.c (get_next_display_element)
14820 (fill_composite_glyph_string): Add comments about special meaning
14821 of TAB characters in a composition.
14823 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14825 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14826 This occurs when processing a multibyte format.
14827 Problem reported by Wolfgang Jenker.
14829 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14831 * xdisp.c (try_cursor_movement): Only check for exact match if
14832 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14834 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14836 Remove unused external symbols.
14837 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14838 * xdisp.c (calc_pixel_width_or_height): Now static.
14839 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14840 * indent.c (check_display_width):
14841 * w32term.c: Fix comment to match code.
14842 * xterm.c, xterm.h (x_catching_errors): Remove.
14844 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14846 * xselect.c: Use signed conversions more consistently (Bug#9498).
14847 (selection_data_to_lisp_data): Assume incoming selection data are
14848 signed integers, not unsigned. This is to be consistent with
14849 outgoing selection data, which was modified to use signed integers
14850 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14851 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14852 expects long, not unsigned long.
14854 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14856 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14857 computation of loop end. Reported by Johan Bockgård
14860 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14862 * frame.c (Fother_visible_frames_p): Function deleted.
14864 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14866 * indent.c (compute_motion): Process display vector front to back
14867 rather than the other way around. (Bug#2496)
14869 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14871 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14873 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14875 * minibuf.c (Fread_from_minibuffer): Doc fix.
14877 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14879 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14880 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14882 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14884 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14885 value for non-existent files.
14887 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14889 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14890 set its "size" to -1. This will set the modtime_size field of
14891 the corresponding buffer to -1, which is what
14892 verify-visited-file-modtime expects for files that do not exist.
14895 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14897 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14899 * lisp.h: ... from here. push_key_description is no longer
14900 defined in keyboard.c, so its declaration should not be in
14901 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14902 logically belongs with push_key_description.
14904 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14906 * buffer.h: Include <sys/types.h> instead of <time.h>.
14907 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14908 Problem reported by Herbert J. Skuhra.
14910 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14912 * xml.c (parse_region): Make the parsing work for
14913 non-comment-starting XML files again (bug#9144).
14915 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14917 * image.c (gif_load): Fix calculation of bottom and right corner.
14920 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14922 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14923 redisplay in small windows.
14925 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14927 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14929 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14931 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14932 Operate on live windows only.
14934 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14936 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14938 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14940 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14941 only under bidi iteration.
14943 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14945 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14947 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14949 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14950 Without this fix, the command to link temacs failed due to an
14951 undefined symbol __builtin_isnan. This is because
14952 /usr/include/iso/math_c99.h #defines isnan(x) to
14953 __builtin_isnan(x), but the bundled gcc, which identifies itself
14954 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14956 * floatfns.c (isnan): #undef, and then #define to a clone of
14958 (Fisnan): Always define, since it's always available now.
14959 (syms_of_floatfns): Always define isnan at the Lisp level.
14961 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14963 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14965 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14967 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14968 The previous code assumed that file offsets (off_t values) fit in
14969 EMACS_INT variables, which is not true on typical 32-bit hosts.
14970 The code messed up by falsely reporting buffer overflow in cases
14971 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14972 when "big" contains more than 2**29 bytes, even though this
14973 inserts just one byte and does not overflow the buffer.
14974 (Finsert_file_contents): Store file offsets as off_t
14975 values, not as EMACS_INT values. Check for overflow when
14976 converting between EMACS_INT and off_t. When checking for
14977 buffer overflow or for overlap, take the offsets into account.
14978 Don't use EMACS_INT for small values where int suffices.
14979 When checking for overlap, fix a typo: ZV was used where
14980 ZV_BYTE was intended.
14981 (Fwrite_region): Don't assume off_t fits into 'long'.
14982 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14984 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14986 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14988 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14990 sprintf-related integer and memory overflow issues (Bug#9412).
14992 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14993 (esprintf, exprintf, evxprintf): New functions.
14994 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14995 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14996 (modify_event_symbol): Do not assume that the length of
14997 name_alist_or_stem is safe to alloca and fits in int.
14998 (Fexecute_extended_command): Likewise for function name and binding.
14999 (Frecursion_depth): Wrap around reliably on integer overflow.
15000 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15001 since some callers pass EMACS_INT values.
15002 (Fsingle_key_description): Don't crash if symbol name contains more
15003 than MAX_ALLOCA bytes.
15004 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15005 (get_minibuffer): Arg is now EMACS_INT, not int.
15006 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15007 (esprintf, exprintf, evxprintf): New decls.
15008 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15010 * dbusbind.c (signature_cat): New function.
15011 (xd_signature, Fdbus_register_signal):
15012 Do not overrun buffer; instead, report string overflow.
15014 * dispnew.c (add_window_display_history): Don't overrun buffer.
15015 Truncate instead; this is OK since it's just a log.
15017 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15018 even if the time zone offset is outlandishly large.
15019 Don't mishandle offset == INT_MIN.
15021 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15022 when creating daemon; the previous buffer-overflow check was incorrect.
15024 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15025 which has the guts of the old verror function.
15027 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15028 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15030 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15031 (font_unparse_xlfd): Don't blindly alloca long strings.
15032 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15033 fits in int, when using sprintf. Use single snprintf to count
15034 length of string rather than counting it via multiple sprintfs;
15035 that's simpler and more reliable.
15036 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15037 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15038 sprintf, in case result does not fit in int.
15040 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15041 (fontset_from_font): Print it.
15043 * frame.c (tty_frame_count): Now printmax_t, not int.
15044 (make_terminal_frame, set_term_frame_name): Print it.
15045 (x_report_frame_params): In X, window IDs are unsigned long,
15046 not signed long, so print them as unsigned.
15047 (validate_x_resource_name): Check for implausibly long names,
15048 and don't assume name length fits in 'int'.
15049 (x_get_resource_string): Don't blindly alloca invocation name;
15050 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15053 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15054 (xg_check_special_colors, xg_set_geometry):
15055 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15057 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15058 Use esprintf, not sprintf, in case result does not fit in int.
15060 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15061 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15062 it as a large positive number.
15063 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15064 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15066 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15067 in case result does not fit in int.
15069 * print.c (float_to_string): Detect width overflow more reliably.
15070 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15071 buffer overrun. Don't assume list length fits in 'int'. Treat
15072 print length of 0 as 0, not as infinity; to be consistent with other
15073 uses of print length in this function. Don't overflow print length
15074 index. Don't assume hash table size fits in 'long', or that
15075 vectorlike size fits in 'unsigned long'.
15077 * process.c (make_process): Use printmax_t, not int, to format
15078 process-name gensyms.
15080 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15082 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15083 to avoid potential buffer overrun.
15085 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15086 if X resource line is longer than 512 bytes.
15088 * xfns.c (x_window): Make sprintf buffer a bit bigger
15089 to avoid potential buffer overrun.
15091 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15093 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15095 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15097 Integer overflow fixes for scrolling, etc.
15098 Without these, Emacs silently mishandles large integers sometimes.
15099 For example, "C-u 4294967297 M-x recenter" was treated as if
15100 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15102 * xdisp.c (try_window_id): Check Emacs fixnum range before
15103 converting to 'int'.
15105 * window.c (window_scroll_line_based, Frecenter):
15106 Check that an Emacs fixnum is in range before assigning it to 'int'.
15107 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15108 values converted from Emacs fixnums.
15109 (Frecenter): Don't wrap around a line count if it is out of 'int'
15110 range; instead, treat it as an extreme value.
15111 (Fset_window_configuration, compare_window_configurations):
15112 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15114 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15115 that can exceed INT_MAX. Check that EMACS_INT value is in range
15116 before assigning it to the (possibly-narrower) index.
15117 (match_limit): Don't assume that a fixnum can fit in 'int'.
15119 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15122 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15123 (Fvertical_motion): Don't wrap around LINES values that don't fit
15124 in 'int'. Instead, treat them as extreme values. This is good
15125 enough for windows, which can't have more than INT_MAX lines anyway.
15127 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15129 * Require libxml/parser.h to avoid compilation warning.
15131 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15133 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15134 since this reportedly can destroy thread storage.
15136 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15138 * syntax.c (find_defun_start): Update all cache variables if
15139 exiting early (Bug#9401).
15141 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15143 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15145 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15146 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15147 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15149 * term.c (tty_append_glyph): New function.
15150 (produce_stretch_glyph): Static function and its prototype deleted.

15157 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15158 when checking :margin (Bug#9390).
15159 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15160 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15161 so that the name doesn't mislead. All uses changed.
15163 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15165 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15168 2011-08-27 Eli Zaretskii <eliz@gnu.org>

15171 position beyond to_charpos, if we are scanning backwards.
15172 (move_it_vertically_backward): When DY == 0, make sure we get to
15173 the first character in the line after the newline.
15175 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15177 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15178 (ccl_driver): Do not generate an out-of-range pointer.
15179 (Fccl_execute_on_string): Remove unnecessary check for
15180 integer overflow, noted by Stefan Monnier in
15181 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15182 Remove a FIXME that didn't need fixing.
15183 Simplify the newly-introduced buffer reallocation code.
15185 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15187 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15189 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15191 Integer and memory overflow issues (Bug#9196).
15193 * doc.c (get_doc_string): Rework so that
15194 get_doc_string_buffer_size is the actual buffer size, rather than
15195 being 1 less than the actual buffer size; this makes xpalloc more
15198 * image.c (x_allocate_bitmap_record, cache_image):
15199 * xselect.c (Fx_register_dnd_atom):
15200 Simplify previous changes by using xpalloc.
15202 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15203 since either will do and ptrdiff_t is convenient with xpalloc.
15205 * charset.c (charset_table_size)
15206 (struct charset_sort_data.priority): Now ptrdiff_t.
15207 (charset_compare): Don't overflow if priorities differ greatly.
15208 (Fsort_charsets): Don't assume list length fits in int.
15209 Check for size-calculation overflow when allocating sort data.
15210 (syms_of_charset): Allocate an initial charset table that is
15211 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15213 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15215 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15216 The actual value is always <= INT_MAX, and leaving it unsigned made
15217 overflow checking harder.
15219 * dispextern.h (struct glyph_matrix.rows_allocated)
15220 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15221 with xpalloc. The values are still always <= INT_MAX.
15223 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15225 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15226 (SAFE_NALLOCA): New macro.
15228 * region-cache.c (struct boundary.pos, find_cache_boundary)
15229 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15230 (set_cache_region, invalidate_region_cache)
15231 (revalidate_region_cache, know_region_cache, region_cache_forward)
15232 (region_cache_backward, pp_cache):
15233 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15234 so that ptrdiff_t * can be passed to xpalloc.
15235 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15236 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15237 (pp_cache): Don't assume cache_len fits in int.
15238 * region-cache.h: Adjust extern decls to match.
15240 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15241 EMACS_INT, since either will do, for xpalloc.
15243 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15244 (xnmalloc, xnrealloc, xpalloc): New functions.
15246 * bidi.c (bidi_shelve_header_size): New constant.
15247 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15248 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15250 * bidi.c (bidi_cache_shrink):
15251 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15253 Don't update size of array until after memory allocation succeeds,
15254 because xmalloc/xrealloc may not return.
15255 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15256 now that we have proper integer overflow checking.
15257 (record_overlay_string, overlay_strings): Catch overflows when
15258 calculating size of overlay_str_buf.
15260 * callproc.c (Fcall_process): Check for size overflow when
15261 calculating size of args2.
15262 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15263 Normally we prefer signed values, but sticking with ptrdiff_t would
15264 require adding more-complicated checks.
15266 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15267 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15268 Redo buffer-overflow calculations to avoid integer overflow.
15269 Add a FIXME comment where memory seems to be over-allocated.
15271 * character.c (Fstring): Check for size-calculation overflow.
15273 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15274 unnecessary integer overflow. Check for size overflow.
15275 (encode_coding_object): Don't update size until xmalloc succeeds.
15277 * composite.c (get_composition_id): Check for overflow in glyph
15278 length calculations.
15280 Integer and memory overflow fixes for display code.
15281 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15282 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15283 (scrolling_window): Check for overflow in size calculations.

15295 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15296 (get_doc_string): Check for size calculation overflow.
15297 Don't update size until allocation succeeds.
15298 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15299 EMACS_INT, where ptrdiff_t will do.
15300 (Fsubstitute_command_keys): Check for string overflow.
15302 * editfns.c (set_time_zone_rule): Don't assume environment length
15304 (message_length): Now ptrdiff_t, not int.
15305 (Fmessage_box): Don't update size until allocation succeeds.
15306 Don't assume message length fits in int.
15307 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15309 * emacs.c (main): Do not reallocate argv, since there is a null at
15310 the end that can be overwritten, and this way there's no need to
15311 worry about size-calculation overflow.
15312 (sort_args): Check for size-calculation overflow.
15314 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15316 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15318 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15319 (x_set_scroll_bar_width, x_figure_window_size):
15320 Check for integer overflow.
15321 (x_set_alpha): Do not assume XINT fits in int.
15323 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15324 This is for the members text_lines, text_cols, total_lines, total_cols,
15325 where the system imposes an 'int' limit.
15327 * fringe.c (Fdefine_fringe_bitmap):
15328 Don't update size until alloc works.
15330 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15331 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15333 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15334 Check for size-calculation overflow.
15335 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15336 do, as we prefer signed integers.
15337 (id_to_widget.max_size, id_to_widget.used)
15338 (xg_store_widget_in_map, xg_remove_widget_from_map)
15339 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15340 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15341 Use and return ptrdiff_t, not int.
15342 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15343 * gtkutil.h: Change prototypes to match the above.
15345 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15346 are duplicate now that they've been promoted to lisp.h.
15347 (x_allocate_bitmap_record, x_alloc_image_color)
15348 (make_image_cache, cache_image, xpm_load):

15360 Use ptrdiff_t, not int, to count maps.
15361 (read_char_minibuf_menu_prompt): Check for overflow in size
15362 calculations. Don't update size until allocation succeeds.
15363 Redo calculations to avoid overflow.
15364 * keyboard.h: Change prototypes to match the above.
15366 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

15392 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15393 for command line length. Do not attempt to address one before the
15394 beginning of an array, as that's not portable.
15396 * term.c (max_frame_lines): Remove; unused.
15397 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15399 (encode_terminal_code, calculate_costs): Check for size
15400 calculation overflow.

15406 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15407 subtracting pointers.
15408 (gobble_line): Check for overflow more carefully. Don't update size

15422 Use ptrdiff_t, not int, for sizes.
15423 (Finternal_make_lisp_face, cache_face):
15424 Check for size calculation overflow.
15425 (cache_face): Treat size calculation overflows as if they were
15426 memory exhaustion (the usual treatment), rather than aborting.
15428 * xfns.c (x_encode_text, x_set_name_internal)
15429 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15430 sizes, since they can exceed INT_MAX in size. Check for size
15431 calculation overflow.
15433 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15434 (xg_select): Check for size calculation overflow.
15435 Don't update size until alloc done.
15437 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15438 as sprintf is limited to int lengths.
15440 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15441 (X_LONG_MIN): New macros.
15442 Use them to make the following changes clearer.
15443 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15444 This change doesn't affect the value now, but it may help remind
15445 future maintainers not to raise the value too much later.
15446 (SELECTION_QUANTUM): Remove, replacing with ...
15447 (selection_quantum): ... new function, which avoids overflow.
15449 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15450 assumption that selection length fits in 'int'.

15463 (lisp_data_to_selection_data, x_property_data_to_lisp):

15465 (x_get_window_property, receive_incremental_selection)
15466 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15467 Don't store size until memory allocation succeeds.
15468 (x_get_window_property): Plug memory leak on memory exhaustion.
15469 Don't double-block input; malloc is safe here. Don't assume 2**34
15470 - 4 fits in unsigned long. Add an xassert to check
15471 XGetWindowProperty overflow. Be more careful about overflow
15472 calculations, and distinguish size from memory overflow better.
15473 (receive_incremental_selection): When tracing, don't assume
15474 unsigned int is less than INT_MAX.
15475 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15476 harmful) conversions of unsigned short to int.
15477 (lisp_data_to_selection_data): Don't assume that integers
15478 in the range -65535 through -1 fit in an X unsigned short.
15479 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15480 result parameters unless successful. Rely on cons_to_unsigned
15481 to report problems with elements; the old code wasn't right anyway.
15482 (x_check_property_data): Check for int overflow; we cannot use
15483 a wider type due to X limits.
15484 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15486 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15516 * lisp.h (hash_lookup, hash_put):
15517 * minibuf.c (Ftest_completion):
15518 Use ptrdiff_t for hash table indexes, not int (which is too
15519 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15520 32-bit --with-wide-int hosts).
15522 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15523 Add a FIXME comment about memory leaks.
15524 (syms_of_charset): Don't assume xmalloc returns.

15528 * character.h (CHAR_WIDTH):
15529 * indent.c (MULTIBYTE_BYTES_WIDTH):
15530 Use sanitize_char_width to avoid undefined and/or bad behavior
15531 with outlandish widths.
15532 * character.h (sanitize_tab_width): Rename from sanitize_width,
15533 now that we have two such functions. All uses changed.
15534 (sanitize_char_width): New inline function.
15536 Don't assume that tab-width fits in int.
15537 * character.h (sanitize_width): New inline function.

15544 * fileio.c: Integer overflow issues with file modes.
15545 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15547 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

15554 exceed limits imposed by XClientMessageEvent, as well as the usual
15555 ptrdiff_t and size_t limits.
15557 * keyboard.c: Overflow, signedness and related fixes.
15558 (make_lispy_movement): Use same integer type in forward decl
15559 that is used in the definition.
15560 (read_key_sequence, keyremap_step):
15561 Change bufsize argument back to int, undoing my 2011-03-30 change.
15562 We prefer signed types, and int is wide enough here.
15563 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15564 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15565 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15566 length, not size_t. Use ptrdiff_t for index, not int.
15567 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15568 possibility of integer overflow.
15570 Overflow, signedness and related fixes for images.

15596 Prefer int to unsigned where either will do.
15597 (tiff_handler): New function, combining the cores of the
15598 old tiff_error_handler and tiff_warning_handler.
15599 This function is rewritten to use vsnprintf and thereby avoid
15600 stack buffer overflows. It uses only the features of vsnprintf
15601 that are common to both POSIX and native Microsoft.
15602 (tiff_error_handler, tiff_warning_handler): Use it.
15603 (tiff_load, gif_load, imagemagick_load_image):
15604 Don't assume :index value fits in 'int'.
15605 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15606 (imagemagick_load_image): Check that crop parameters fit into
15607 the integer types that MagickCropImage accepts. Don't assume
15608 Vimagemagick_render_type has a nonnegative value. Don't assume
15609 size_t fits in 'long'.
15610 (gs_load): Use printmax_t to print the widest integers possible.
15611 Check for integer overflow when computing image height and width.
15613 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15615 * xdisp.c (redisplay_window): Don't force window start if point

15624 (handle_single_display_spec): If the display spec is of the form
15625 `(space ...)', and specifies display in the text area, return 2
15627 (try_cursor_movement): Check for the need to scroll more
15628 accurately, and prefer exact match for point under bidi.
15629 Don't advance `row' beyond the last row of the window.
15631 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15632 into disp_prop; all users changed.

15646 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15647 buffers, return left-to-right.
15648 (set_cursor_from_row): Consider candidate row a win if its glyph
15649 represents a newline and point is on that newline. Fixes cursor
15650 positioning on the newline at EOL of R2L text within L2R
15651 paragraph, and vice versa.
15652 (try_cursor_movement): Check continued rows, in addition to
15653 continuation rows. Fixes unwarranted scroll when point enters a
15654 continued line of R2L text within an L2R paragraph, or vice versa.
15655 (cursor_row_p): Consider the case of point being equal to
15656 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15657 from the end of a short line to the beginning of a continued line
15658 of R2L text within L2R paragraph.

15680 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15682 * xdisp.c (redisplay_window): When computing centering_position,
15683 account for the height of the header line. (Bug#8874)
15685 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15686 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15687 candidate is selected by the mouse, and that candidate has a
15688 composed character under the mouse.
15690 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15691 coordinates reported by pos-visible-in-window-p for a composed
15692 character in column zero.
15694 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15700 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15701 consider it a hit if to_charpos is anywhere in the range of the
15702 composed buffer positions.
15704 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15706 * image.c (gif_load): Don't assume that each subimage has the same
15707 dimensions as the base image. Handle disposal method that is
15708 "undefined" by the gif spec (Bug#9335).
15710 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15712 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15717 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15718 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15719 from an Org mode buffer to a Speedbar frame.
15721 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15722 a composition, take its buffer position from IT->cmp_it.charpos.
15723 Fixes cursor positioning at the beginning of a line that begins
15724 with a composed character.
15726 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15728 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15729 character bidirectional type, use STRONG_L instead. Fixes crashes
15730 in a buffer produced by `describe-categories'.
15732 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15733 members before the level stack, so they would be saved and
15734 restored when copying iterator state. Fixes incorrect reordering
15735 around TABs covered by display properties.
15737 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15739 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15823 the event loop. Get status from as_status (Bug#7276).
15825 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15826 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15827 the event loop (Bug#7276).
15829 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15853 (Fnetwork_interface_list): Allocate in increments of bytes instead
15854 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15855 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct

15869 entry. Force push_it to save on the stack the current
15870 buffer/string position, to be restored by pop_it. Fix flags in
15871 the iterator structure wrt the object coming from a display
15872 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15873 properties. (Bug#9284)
15875 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>

15921 is non-zero, even if the data buffer is NULL. Fixes a crash in
15922 vertical-motion with longlines-mode. (Bug#9254)
15924 2011-08-05 Eli Zaretskii <eliz@gnu.org>

16050 (x_set_background_color): Likewise.
16052 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16053 contents (Bug#9176).
16054 (EmacsTooltip -init): Remove bezels and add shadows to
16057 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16058 or scroll bar (Bug#8470).
16060 * nsfont.m (nsfont_open): Remove assignment to voffset and
16061 unnecessary vars hshink, expand, hd, full_height, min_height.
16062 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16064 * nsterm.h (nsfont_info): Remove voffset field.
16066 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16068 Implement strike-through and overline on NextStep (Bug#8863).
16070 * nsfont.m (nsfont_open): Use underline position provided by font,
16071 instead of hard-coded value of 2.
16072 (nsfont_draw): Call ns_draw_text_decoration instead.
16074 * nsterm.h: Add declaration for ns_draw_text_decoration.
16076 * nsterm.m (ns_draw_text_decoration): New function for drawing
16077 underline, overline, and strike-through.
16078 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16079 ns_draw_text_decoration. Change treatment of cursor drawing to
16080 accommodate underlining, etc.
16082 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16084 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16087 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16089 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16090 Without this fix, if a signal arrives just after memory fills up,
16091 'malloc' might be invoked reentrantly.
16093 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16094 In other words, assume that every image size is allowed, on non-X
16095 hosts. This assumption is probably wrong, but it lets Emacs compile.
16097 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16099 * regex.c (re_iswctype): Convert return values to boolean.
16101 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16103 * xdisp.c (compute_display_string_pos): Don't use cached display
16104 string position if the buffer had its restriction changed.
16107 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16109 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16111 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16113 Integer signedness and overflow and related fixes. (Bug#9079)
16115 * bidi.c: Integer size and overflow fixes.
16116 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16117 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16118 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16119 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16120 (bidi_find_other_level_edge):
16121 Use ptrdiff_t instead of EMACS_INT where either will do.
16122 This works better on 32-bit hosts configured --with-wide-int.
16123 (bidi_cache_ensure_space): Check for size-calculation overflow.
16124 Use % rather than repeated addition, for better worst-case speed.
16125 Don't set bidi_cache_size until after xrealloc returns, because it
16127 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16128 (bidi_cache_ensure_space): Also check that the bidi cache size
16129 does not exceed that of the largest Lisp string or buffer. See Eli
16130 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16132 * alloc.c (__malloc_size_t): Remove.
16133 All uses replaced by size_t. See Andreas Schwab's note
16134 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16136 * image.c: Improve checking for integer overflow.
16137 (check_image_size): Assume that f is nonnull, since
16138 it is always nonnull in practice. This is one less thing to
16139 worry about when checking for integer overflow later.
16140 (x_check_image_size): New function, which checks for integer
16141 overflow issues inside X.
16142 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16143 This removes the need for a memory_full check.
16144 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16145 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16146 (xbm_read_bitmap_data): Change locals back to 'int', since
16147 their values must fit in 'int'.
16148 (xpm_load_image, png_load, tiff_load):
16149 Invoke x_create_x_image_and_pixmap earlier,
16150 to avoid much needless work if the image is too large.
16151 (tiff_load): Treat overly large images as if
16152 x_create_x_image_and_pixmap failed, not as malloc failures.
16153 (gs_load): Use x_check_image_size.
16155 * gtkutil.c: Omit integer casts.
16156 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16157 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16159 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16161 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16162 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16163 would wrongly return t on a 64-bit host.
16165 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16166 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16167 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16168 and therefore cause GCC to emit a bogus diagnostic in some cases.
16170 * image.c: Integer signedness and overflow and related fixes.
16171 This is not an exhaustive set of fixes, but it's time to
16172 record what I've got.
16173 (lookup_pixel_color, check_image_size): Remove redundant decls.
16174 (check_image_size): Don't assume that arbitrary EMACS_INT values
16175 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16176 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16177 (tiff_load, imagemagick_load_image):
16178 Check for overflow in size calculations.
16179 (x_create_x_image_and_pixmap): Remove unnecessary test for
16180 xmalloc returning NULL; that can't happen.
16181 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16182 (xpm_color_bucket): Use better integer hashing function.
16183 (xpm_cache_color): Don't possibly over-allocate memory.
16184 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16185 (gif_memory_source):
16186 Use ptrdiff_t, not int or size_t, to record sizes.
16187 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16188 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16189 either works, as we prefer signed integers.
16190 (tiff_read_from_memory, tiff_write_from_memory):
16191 Return tsize_t, not size_t, since that's what the TIFF API wants.
16192 (tiff_read_from_memory): Don't fail simply because the read would
16193 go past EOF; instead, return a short read.
16194 (tiff_load): Omit no-longer-needed casts.
16195 (Fimagemagick_types): Don't assume size fits into 'int'.
16197 Improve hashing quality when configured --with-wide-int.
16198 * fns.c (hash_string): New function, taken from sxhash_string.
16199 Do not discard information about ASCII character case; this
16200 discarding is no longer needed.
16201 (sxhash-string): Use it. Change sig to match it. Caller changed.
16202 * lisp.h: Declare it.
16203 * lread.c (hash_string): Remove, since we now use fns.c's version.
16204 The fns.c version returns a wider integer if --with-wide-int is
16205 specified, so this should help the quality of the hashing a bit.
16207 * emacs.c: Integer overflow minor fix.
16208 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16209 Define only if GNU_LINUX.
16210 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16212 * dispnew.c: Integer signedness and overflow fixes.
16213 Remove unnecessary forward decls, that were a maintenance hassle.
16214 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16216 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16217 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16218 (prepare_desired_row, line_draw_cost):
16219 Use int, not unsigned, where either works.
16220 (save_current_matrix, restore_current_matrix):
16221 Use ptrdiff_t, not size_t, where either works.
16222 (init_display): Check for overflow more accurately, and without
16223 relying on undefined behavior.
16225 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16226 Remove, replacing with the new symbols in lisp.h. All uses changed.
16227 * fileio.c (make_temp_name):
16228 * filelock.c (lock_file_1, lock_file):
16229 * xdisp.c (message_dolog):
16230 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16231 Use pMd etc. instead.
16232 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16233 replacing the pWIDE etc. symbols removed from editfns.c.
16235 * keyboard.h (num_input_events): Now uintmax_t.
16236 This is (very slightly) less likely to mess up due to wraparound.
16239 * buffer.c: Integer signedness fixes.
16240 (alloc_buffer_text, enlarge_buffer_text):
16241 Use ptrdiff_t rather than size_t when either will do, as we prefer
16244 * alloc.c: Integer signedness and overflow fixes.
16245 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16246 (__malloc_size_t): Default to size_t, not to int.
16247 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16248 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16249 Prefer ptrdiff_t to size_t when either would do, as we prefer
16251 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16252 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16253 Now const. Initialize with values that are in range even if char
16255 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16256 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16257 These functions do the right thing with sizes > 2**32.
16258 (check_depth): Now ptrdiff_t, not int.
16259 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16260 Adjust to new way of storing sizes. Check for size overflow bugs
16262 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16263 slightly wrong anyway, as it missed one instance of
16264 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16265 (refill_memory_reserve): Omit needless cast to size_t.
16266 (mark_object_loop_halt): Mark as externally visible.
16268 * xselect.c: Integer signedness and overflow fixes.
16269 (Fx_register_dnd_atom, x_handle_dnd_message):
16270 Use ptrdiff_t, not size_t, since we prefer signed.
16271 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16272 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16273 x_dnd_atoms_size and x_dnd_atoms_length.
16275 * doprnt.c: Prefer signed to unsigned when either works.
16277 * doprnt.c (doprnt):
16279 * xdisp.c (vmessage):
16280 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16281 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16282 prefer signed arithmetic to avoid comparison confusion.
16283 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16284 but is a bit tricky.
16286 Assume freestanding C89 headers, string.h, stdlib.h.
16287 * data.c, doprnt.c, floatfns.c, print.c:
16288 Include float.h unconditionally.
16289 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16290 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16291 * regex.c: Likewise for stddef.h, string.h.
16292 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16293 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16294 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16295 (STDC_HEADERS): Remove obsolete defines.
16296 * sysdep.c: Include limits.h unconditionally.
16298 Assume support for memcmp, memcpy, memmove, memset.
16299 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16300 * regex.c (memcmp, memcpy):
16301 Remove; we assume C89 now.
16303 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16304 (__malloc_safe_bcopy): Remove; no longer needed.
16306 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16307 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16308 well either way, and we prefer signed to unsigned.
16310 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16312 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16313 closes the connection while we're reading (bug#9182).
16315 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16317 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16318 are specified (Bug#9168).
16320 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16322 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16323 Found by GCC static checking and --with-wide-int on a 32-bit host.
16325 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16327 * xdisp.c (compute_display_string_pos): Fix logic of caching
16328 previous display string position. Initialize cached_prev_pos to
16329 -1. Fixes slow-down at the beginning of a buffer.
16331 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16333 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16334 for attrs[LFACE_FONTSET_INDEX].
16336 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16338 * xml.c (parse_region): Remove unused local
16339 that was recently introduced.
16341 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16343 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16344 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16346 * xdisp.c (move_it_in_display_line_to): Record the best matching
16347 position for TO_CHARPOS while scanning the line, and restore it on
16348 exit if none of the characters scanned was an exact match.
16349 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16350 when exact match is impossible due to invisible text, and the
16351 lines are truncated.
16353 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16355 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16358 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16360 Fix a significant slow-down of cursor motion with C-n, C-p,
16361 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16362 auto-repeat under bidi redisplay in fontified buffers.
16363 * xdisp.c (compute_stop_pos_backwards): New function.
16364 (next_element_from_buffer): Call compute_stop_pos_backwards to
16365 find a suitable prev_stop when we find ourselves before
16367 (reseat): Don't look for prev_stop, as that could mean a very long
16369 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16370 <cached_disp_overlay_modiff>: Cache for last found display string
16372 (compute_display_string_pos): Return the cached position if asked
16373 about the same buffer in the same area of character positions, and
16374 the buffer wasn't changed since the time the display string
16375 position was cached.
16377 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16379 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16380 is an integer, which is important for empty lines. (Bug#9149)
16382 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16384 * frame.c (Fmodify_frame_parameters): In tty case, update the
16385 default face if necessary (Bug#4238).
16387 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16389 * editfns.c (Fstring_to_char): No need to explain what a character
16390 is in the docstring (Bug#6576).
16392 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16394 * xml.c (parse_region): Make sure we always return a tree.
16396 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16398 * xml.c (parse_region): If a document contains only comments,
16401 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16403 * xml.c (make_dom): Return comments, too.
16405 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16408 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16409 and the surrounding thread.
16410 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16411 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16412 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16414 * s/openbsd.h (BROKEN_SIGIO): Define.
16415 * unexelf.c (unexec) [__OpenBSD__]:
16416 Don't update the .mdebug section of the Alpha COFF symbol table.
16418 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16420 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16423 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16425 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16426 This fixes some race conditions on the permissions of any newly
16429 * alloc.c (valid_pointer_p): Use pipe, not open.
16430 This fixes some permissions issues when debugging.
16432 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16433 If fchown fails to set both uid and gid, try to set just gid,
16434 as that is sometimes allowed. Adjust the file's mode to eliminate
16435 setuid or setgid bits that are inappropriate if fchown fails.
16437 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16439 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16440 to compare Lisp_Objects.
16441 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16442 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16443 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16445 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16447 * lread.c (read_integer): Unread even EOF character.
16448 (read1): Likewise. Properly record start position of symbol.
16450 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16451 symbol character follows.
16453 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16455 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16456 This works around a problem with the previous change to Fcopy_file.
16457 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16458 and without this change, GCC might complain about discarding
16459 fchown's return value.
16461 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16463 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16465 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16467 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16469 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16471 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16472 it's used from the C level.
16474 * process.c: Use the same condition for POLL_FOR_INPUT in both
16475 keyboard.c and process.c (bug#1858).
16477 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16479 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16480 (Fgnutls_boot): Use it.
16482 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16484 * doc.c (Fsubstitute_command_keys): Revert last change.
16486 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16488 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16489 quotes the next character, and doesn't affect other longer
16490 sequences (bug#8935).
16492 * lread.c (syms_of_lread): Clarify that is isn't only

16557 the iterator is before prev_stop.
16558 (init_iterator): Initialize bidi_p from the default value of

17039 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17076 Random fixes. E.g., (random) never returned negative values.
17077 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17078 subseconds part to the entropy, as that's a bit more random.
17079 Prefer signed to unsigned, since the signedness doesn't matter and
17080 in general we prefer signed. When given a limit, use a
17081 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17082 latter isn't right if USE_2_TAGS_FOR_INTS.
17083 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17084 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17108 error be more correct.
17110 * fns.c (Frequire): Remove the mention of the .gz files, since

17124 Qgnutls_bootprop_verify_error (which is no longer used).
17126 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17127 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17128 Also (re)move comments that are misplaced or no longer relevant.

17229 * eval.c (struct backtrace): Simplify and port the data structure.
17230 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17231 signed bit field, as this assumption is not portable and it makes
17232 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17233 "char debug_on_exit : 1" as this is not portable either; instead,
17234 use the portable "unsigned int debug_on_exit : 1". Remove unused
17235 member evalargs. Remove obsolete comments about cc bombing out.

17395 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
17397 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
17399 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17401 Integer and buffer overflow fixes (Bug#8873).
17403 * print.c (printchar, strout): Check for string overflow.
17404 (PRINTPREPARE, printchar, strout):
17405 Don't set size unless allocation succeeds.
17407 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17408 for sizes. Check for string overflow more accurately.
17409 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17411 * macros.c: Integer and buffer overflow fixes.
17412 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17413 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17414 Use ptrdiff_t, not int, for sizes.
17415 Don't increment bufsize until after realloc succeeds.
17416 Check for size-calculation overflow.
17417 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17419 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17421 * lread.c: Integer overflow fixes.
17422 (read_integer): Radix is now EMACS_INT, not int,
17423 to improve quality of diagnostics for out-of-range radices.
17424 Calculate buffer size correctly for out-of-range radices.
17425 (read1): Check for integer overflow in radices, and in
17426 read-circle numbers.
17427 (read_escape): Avoid int overflow.
17428 (Fload, openp, read_buffer_size, read1)
17429 (substitute_object_recurse, read_vector, read_list, map_obarray):
17430 Use ptrdiff_t, not int, for sizes.
17431 (read1): Use EMACS_INT, not int, for sizes.
17432 Check for size overflow.
17434 * image.c (cache_image): Check for size arithmetic overflow.
17436 * lread.c: Integer overflow issues.
17437 (saved_doc_string_size, saved_doc_string_length)
17438 (prev_saved_doc_string_size, prev_saved_doc_string_length):
17439 Now ptrdiff_t, not int.
17440 (read1): Don't assume doc string length fits in int. Check for
17441 out-of-range doc string lengths.
17442 (read_list): Don't assume file position fits in int.
17443 (read_escape): Check for hex character overflow.
17445 2011-06-22 Leo Liu <sdl.web@gmail.com>
17447 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17448 Move to minibuffer.el.
17450 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17452 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17453 The following patches are for when GLYPH_DEBUG && !XASSERT.
17454 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17455 * dispnew.c (flush_stdout):
17456 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17457 Mark as externally visible.
17458 * dispnew.c (check_window_matrix_pointers): Now static.
17459 * dispnew.c (window_to_frame_vpos):
17460 * xfns.c (unwind_create_frame):
17461 * xterm.c (x_check_font): Remove unused local.
17462 * scroll.c (CHECK_BOUNDS):
17463 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17464 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17465 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17466 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17467 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17469 (debug_method_add): Use va_list and vsprintf rather than relying
17470 on undefined behavior with wrong number of arguments.
17471 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17472 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17473 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17474 since we're not interested in debugging glyphs with old libraries.
17475 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17476 GCC 4.6.0's static checking.
17478 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17480 Integer overflow and signedness fixes (Bug#8873).
17481 A few related buffer overrun fixes, too.

17488 (x_create_bitmap_from_data, x_create_bitmap_from_file)
17489 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17490 (x_create_bitmap_from_xpm_data):
17491 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17492 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17494 * xfaces.c (load_pixmap):
17495 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17496 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17497 (.bitmaps_last, struct x_output.icon_bitmap):
17498 Use ptrdiff_t, not int, for bitmap indexes.
17499 (x_allocate_bitmap_record): Check for size overflow.
17500 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17502 Use ptrdiff_t, not int, for overlay counts.
17503 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17504 * editfns.c (overlays_around, get_pos_property):
17505 * textprop.c (get_char_property_and_overlay):
17506 * xdisp.c (next_overlay_change, note_mouse_highlight):
17507 * xfaces.c (face_at_buffer_position):
17508 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17509 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17510 (Fnext_overlay_change, Fprevious_overlay_change)
17511 (mouse_face_overlay_overlaps, Foverlays_in):
17512 Use ptrdiff_t, not int, for sizes.
17513 (overlays_at, overlays_in): Check for size-calculation overflow.
17515 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17517 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17518 (x_session_initialize): Do not assume string length fits in int.
17520 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17521 This is unlikely, but can occur if DPI is outlandish.
17523 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17524 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17526 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17527 * xrdb.c (magic_file_p, search_magic_path):
17528 Omit last arg SUFFIX; it was always 0. All callers changed.
17529 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17531 * xfont.c (xfont_match): Avoid need for strlen.
17533 * xfns.c: Don't assume strlen fits in int.
17534 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17536 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17537 not unsigned long, as we prefer signed integers. All callers changed.
17538 Detect integer overflow in repeat count.
17539 (message_dolog): Don't assume print length fits in 39 bytes.
17540 (display_mode_element): Don't assume strlen fits in int.
17542 * termcap.c: Don't assume sizes fit in int and never overflow.
17543 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17544 (gobble_line): Check for size-calculation overflow.
17546 * minibuf.c (Fread_buffer):
17547 * lread.c (intern, intern_c_string):
17548 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17549 Don't assume string length fits in int.
17551 * keyboard.c (parse_tool_bar_item):
17552 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17554 * font.c: Don't assume string length fits in int.
17555 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17556 Use ptrdiff_t, not int.
17557 (font_intern_prop): Don't assume string length fits in int.
17558 Don't assume integer property fits in fixnum.
17559 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17561 * filelock.c: Fix some buffer overrun and integer overflow issues.
17562 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17563 Reformulate so as not to need the command string.
17564 Invoke gzip -cd rather than gunzip, as it's more portable.
17565 (lock_info_type, lock_file_1, lock_file):
17566 Don't assume pid_t and time_t fit in unsigned long.
17567 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17568 (current_lock_owner): Prefer signed type for sizes.
17569 Use memcpy, not strncpy, where memcpy is what is really wanted.
17570 Don't assume (via atoi) that time_t and pid_t fit in int.
17571 Check for time_t and/or pid_t out of range, e.g., via a network share.
17572 Don't alloca where an auto var works fine.
17574 * fileio.c: Fix some integer overflow issues.
17575 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17576 Don't assume string length fits in int.
17577 (directory_file_name): Don't assume string length fits in long.
17578 (make_temp_name): Don't assume pid fits in int, or that its print
17579 length is less than 20.
17581 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17583 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17585 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17587 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17588 We prefer signed integers, even for size calculations.
17590 * emacs.c: Don't assume string length fits in 'int'.
17591 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17592 (main): Don't invoke strlen when not needed.
17594 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17595 (XD_DEBUG_MESSAGE): Don't waste a byte.
17597 * callproc.c (getenv_internal_1, getenv_internal)
17598 (Fgetenv_internal):
17599 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17601 * lread.c (invalid_syntax): Omit length argument.
17602 All uses changed. This doesn't fix a bug, but it simplifies the
17603 code away from its former Hollerith-constant appearance, and it's
17604 one less 'int' to worry about when looking at integer-overflow issues.
17605 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17607 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17608 This didn't break anything, but it didn't help either.
17609 It's confusing to put a bogus integer in a place where the actual
17610 value does not matter.
17611 (LIST_END_P): Remove unused macro and its bogus comment.
17612 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17614 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17615 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17617 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17618 We prefer signed types, and the value cannot exceed the EMACS_INT
17619 range anyway (because otherwise the length would not be representable).
17620 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17621 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17622 This avoids a GCC warning when WIDE_EMACS_INT.
17624 * indent.c (sane_tab_width): New function.
17625 (current_column, scan_for_column, Findent_to, position_indentation)
17626 (compute_motion): Use it. This is just for clarity.
17627 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17629 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17631 * lisp.h (lint_assume): New macro.
17632 * composite.c (composition_gstring_put_cache):
17633 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17635 * editfns.c, insdel.c:
17636 Omit unnecessary forward decls, to simplify future changes.
17638 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17640 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17642 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17643 Use much-faster test for byte-length change.
17644 Don't assume string byte-length fits in 'int'.
17645 Check that character arg fits in 'int'.
17646 (mapcar1): Declare byte as byte, for clarity.
17648 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17650 * fns.c (concat): Catch string overflow earlier.
17651 Do not rely on integer wraparound.
17653 * dispextern.h (struct it.overlay_strings_charpos)
17654 (struct it.selective): Now EMACS_INT, not int.
17655 * xdisp.c (forward_to_next_line_start)
17656 (back_to_previous_visible_line_start)
17657 (reseat_at_next_visible_line_start, next_element_from_buffer):
17658 Don't arbitrarily truncate the value of 'selective' to int.
17660 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17662 * composite.c: Don't truncate sizes to 'int'.
17663 (composition_gstring_p, composition_reseat_it)
17664 (composition_adjust_point): Use EMACS_INT, not int.
17665 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17666 not EMACS_UINT, for indexes.
17668 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17670 * buffer.c: Include <verify.h>.
17671 (struct sortvec.priority, struct sortstr.priority):
17672 Now EMACS_INT, not int.
17673 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17674 (struct sortstr.size, record_overlay_string)
17675 (struct sortstrlist.size, struct sortlist.used):
17676 Don't truncate size to int.
17677 (record_overlay_string): Check for size-calculation overflow.
17678 (init_buffer_once): Check at compile-time, not run-time.
17680 2011-06-22 Jim Meyering <meyering@redhat.com>
17682 Don't leak an XBM-image-sized buffer
17683 * image.c (xbm_load): Free the image buffer after using it.
17685 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17688 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17689 that Sun C diagnosed.
17690 * fns.c (secure_hash): Fix pointer signedness issue.
17691 * intervals.c (static_offset_intervals): New function.
17692 (offset_intervals): Use it.
17694 2011-06-21 Leo Liu <sdl.web@gmail.com>
17697 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17700 * fns.c (secure_hash): Rename from crypto_hash_function and change
17701 the first arg to accept symbols.
17702 (Fsecure_hash): New primitive.
17703 (syms_of_fns): New symbols.
17705 2011-06-20 Deniz Dogan <deniz@dogan.se>
17707 * process.c (Fset_process_buffer): Clarify return value in
17710 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17712 * dispnew.c (add_window_display_history): Use BVAR.
17714 * xdisp.c (debug_method_add): Use BVAR.
17715 (check_window_end, dump_glyph_matrix, dump_glyph)
17716 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17718 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17721 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17722 check till after the cache is created in init_frame_faces.
17724 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17726 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17728 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17730 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17731 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17732 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17734 Improve buffer-overflow checking (Bug#8873).
17735 * fileio.c (Finsert_file_contents):
17736 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17737 Remove the old (too-loose) buffer overflow checks.
17738 They weren't needed, since make_gap checks for buffer overflow.
17739 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17740 The old code merely checked for Emacs fixnum overflow, and relied
17741 on undefined (wraparound) behavior. The new code avoids undefined
17742 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17744 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17745 Tune. Don't use wider integers than needed. Don't use alloca.
17746 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17748 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17750 * insdel.c, lisp.h (buffer_overflow): New function.
17751 (insert_from_buffer_1, replace_range, replace_range_2):
17752 * insdel.c (make_gap_larger):
17753 * editfns.c (Finsert_char):
17754 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17756 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17758 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17760 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17762 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17763 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17765 * fileio.c: Don't assume EMACS_INT fits in off_t.
17766 (emacs_lseek): New static function.
17767 (Finsert_file_contents, Fwrite_region): Use it.
17768 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17770 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17772 * fns.c: Don't overflow int when computing a list length.
17773 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17774 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17775 truncation on 64-bit hosts. Check for QUIT every
17776 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17777 faster and is responsive enough.
17778 (Flength): Report an error instead of overflowing an integer.
17779 (Fsafe_length): Return a float if the value is not representable
17780 as a fixnum. This shouldn't happen except in contrived situations.
17781 (Fnthcdr, Fsort): Don't assume list length fits in int.
17782 (Fcopy_sequence): Don't assume vector length fits in int.
17784 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17785 (header_size, word_size): New constants.
17786 (allocate_vectorlike): Don't check size overflow here.
17787 (allocate_vector): Check it here instead, since this is the only
17788 caller of allocate_vectorlike that could cause overflow.
17789 Check that the new vector's length is representable as a fixnum.
17791 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17792 The previous code was bogus. For example, next_almost_prime (32)
17793 returned 39, which is undesirable as it is a multiple of 3; and
17794 next_almost_prime (24) returned 25, which is a multiple of 5 so
17795 why was the code bothering to check for multiples of 7?
17797 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17799 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17801 Variadic C functions now count arguments with ptrdiff_t.
17802 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17803 Back then I didn't know that the Emacs coding style prefers signed int.
17804 Also, in the meantime I found a few more instances where arguments
17805 were being counted with int, which may truncate counts on 64-bit
17806 machines, or EMACS_INT, which may be unnecessarily wide.
17807 * lisp.h (struct Lisp_Subr.function.aMANY)
17808 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17809 Arg counts are now ptrdiff_t, not size_t.
17810 All variadic functions and their callers changed accordingly.
17811 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17812 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17813 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17814 * callint.c (Fcall_interactively): Check arg count for overflow,
17815 to avoid potential buffer overrun. Use signed char, not 'int',
17816 for 'varies' array, so that we needn't bother to check its size
17817 calculation for overflow.
17818 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17819 * eval.c (apply_lambda):
17820 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17821 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17822 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17824 * callint.c (Fcall_interactively): Don't use index var as event count.
17826 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17827 * mem-limits.h (SIZE): Remove; no longer used.
17829 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17831 Remove unnecessary casts.
17832 * xterm.c (x_term_init):
17833 * xfns.c (x_set_border_pixel):
17834 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17835 These aren't needed now that we assume ANSI C.
17837 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17838 It's more likely to cause problems (due to unsigned overflow)
17841 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17843 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17845 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17847 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17849 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17851 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17853 GLYPH_CODE_FACE returns EMACS_INT, not int.
17854 * dispextern.h (merge_faces):
17855 * xfaces.c (merge_faces):
17856 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17857 Don't assume EMACS_INT fits in int.
17859 * character.h (CHAR_VALID_P): Remove unused parameter.
17860 * fontset.c, lisp.h, xdisp.c: All uses changed.
17862 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17864 * fns.c (concat): Minor tuning based on overflow analysis.
17865 This doesn't fix any bugs. Use int to hold character, instead
17866 of constantly refetching from Emacs object. Use XFASTINT, not
17867 XINT, for value known to be a character. Don't bother comparing
17868 a single byte to 0400, as it's always less.
17870 * floatfns.c (Fexpt):
17871 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17873 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17876 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17878 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17879 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17880 incorrectly succeed when S was a string, because 4294967386 was
17881 truncated before it was used.
17883 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17884 Otherwise, an out-of-range integer could cause undefined behavior
17887 * composite.c: Use int, not EMACS_INT, for characters.
17888 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17889 EMACS_INT, for values that are known to be in character range.
17890 This doesn't fix any bugs but is the usual style inside Emacs and
17891 may generate better code on 32-bit machines.
17893 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17894 This is for reasons similar to the recent CHAR_STRING fix.
17895 * charset.c (Fencode_char): Check that character arg is actually
17896 a character. Pass an int to ENCODE_CHAR.
17897 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17898 wider than 'int', as a compile-time check to prevent future regressions
17901 * character.c (char_string): Remove unnecessary casts.
17903 Make sure a 64-bit char is never passed to CHAR_STRING.
17904 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17905 by silently ignoring the top 32 bits, allowing some values
17906 that were far too large to be valid characters.
17907 * character.h: Include <verify.h>.
17908 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17909 arguments are no wider than unsigned, as a compile-time check
17910 to prevent future regressions in this area.
17912 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17913 (Fsubst_char_in_region):
17915 * xdisp.c (decode_mode_spec_coding):
17916 Adjust to CHAR_STRING's new requirement.
17917 * editfns.c (Finsert_char, Fsubst_char_in_region):
17918 * fns.c (concat): Check that character args are actually
17919 characters. Without this test, these functions did the wrong
17920 thing with wildly out-of-range values on 64-bit hosts.
17922 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17923 These casts should not be needed on 32-bit hosts, either.
17924 * keyboard.c (read_char):
17925 * lread.c (Fload): Remove casts to unsigned.
17927 * lisp.h (UNSIGNED_CMP): New macro.
17928 This fixes comparison bugs on 64-bit hosts.
17929 (ASCII_CHAR_P): Use it.
17930 * casefiddle.c (casify_object):
17931 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17932 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17933 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17934 * dispextern.h (FACE_FROM_ID):
17935 * keyboard.c (read_char): Use UNSIGNED_CMP.
17937 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17938 not to EMACS_INT, to avoid GCC warning.
17940 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17942 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17943 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17944 isn't needed on 32-bit machines.
17946 * buffer.c (Fgenerate_new_buffer_name):
17947 Use EMACS_INT for count, not int.
17948 (advance_to_char_boundary): Return EMACS_INT, not int.
17950 * data.c (Qcompiled_function): Now static.
17952 * window.c (window_body_lines): Now static.
17954 * image.c (gif_load): Rename local to avoid shadowing.
17956 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17957 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17958 * alloc.c (make_save_value): Integer argument is now of type
17959 ptrdiff_t, not int.
17960 (mark_object): Use ptrdiff_t, not int.
17961 * lisp.h (pD): New macro.
17962 * print.c (print_object): Use it.
17964 * alloc.c: Use EMACS_INT, not int, to count objects.
17965 (total_conses, total_markers, total_symbols, total_vector_size)
17966 (total_free_conses, total_free_markers, total_free_symbols)
17967 (total_free_floats, total_floats, total_free_intervals)
17968 (total_intervals, total_strings, total_free_strings):
17969 Now EMACS_INT, not int. All uses changed.
17970 (Fgarbage_collect): Compute overall total using a double, so that
17971 integer overflow is less likely to be a problem. Check for overflow
17972 when converting back to an integer.
17973 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17974 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17975 These were 'int' variables that could overflow on 64-bit hosts;
17976 they were never used, so remove them instead of repairing them.
17977 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17978 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17979 Previously, this ceilinged at INT_MAX, but that doesn't work on
17981 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17983 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17984 (allocate_vectorlike): Check for ptrdiff_t overflow.
17985 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17986 when a (possibly-narrower) signed value would do just as well.
17987 We prefer using signed arithmetic, to avoid comparison confusion.
17989 * alloc.c: Catch some string size overflows that we were missing.
17990 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17991 for convenience in STRING_BYTES_MAX.
17992 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17993 The definition here is exact; the one in lisp.h was approximate.
17994 (allocate_string_data): Check for string overflow. This catches
17995 some instances we weren't catching before. Also, it catches
17996 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17997 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17998 and ptrdiff_t and EMACS_INT are both 64 bits.
18000 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18001 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18002 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18004 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18006 * alloc.c (Fmake_string): Check for out-of-range init.
18008 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18010 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18012 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18014 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18015 xg_get_default_scrollbar_width.
18017 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.

18025 and height if HAVE_GTK3 (Bug#8505).
18026 (scroll_bar_width_for_theme): New variable.
18027 (update_theme_scrollbar_width): New function.
18028 (xg_get_default_scrollbar_width): Move code to
18029 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18030 (xg_initialize): Call update_theme_scrollbar_width.
18032 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18034 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18036 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18038 * frame.c (make_frame): Call other_buffer_safely instead of
18041 * window.c (temp_output_buffer_show): Call display_buffer with
18042 second argument Vtemp_buffer_show_specifiers and reset latter
18043 immediately after the call.
18044 (Vtemp_buffer_show_specifiers): New variable.
18045 (auto_window_vscroll_p, next_screen_context_lines)
18046 (Vscroll_preserve_screen_position): Remove leading asterisks from

18069 wasn't returning anything.
18070 (compare_window_configurations): Remove unused locals.
18071 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18072 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18073 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers

18229 Remove static from declaration of Qdelete_window, it's
18230 temporarily needed by Fbury_buffer.
18231 (replace_window): Don't assign orig_top_line and

18610 value of a `display' property is a "replacing spec".
18611 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18612 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18642 * gnutls.c: Use Emacs's memory allocators.
18643 Without this change, the gnutls library would invoke malloc etc.
18644 directly, which causes problems on non-SYNC_INPUT hosts, and which
18645 runs afoul of improving memory_full behavior. (Bug#8761)
18646 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18647 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18648 xfree instead of the default malloc, realloc, free.
18649 (Fgnutls_boot): No need to check for memory allocation failure,
18650 since xmalloc does that for us.

18672 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18673 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18674 * alloc.c (allocate_vectorlike):
18675 Check for overflow in vector size calculations.
18676 * ccl.c (ccl_driver):
18677 Check for overflow when converting EMACS_INT to int.
18678 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18679 need to be updated by these changes.
18680 * fns.c (make_hash_table, maybe_resize_hash_table):
18681 Check for integer overflow with large hash tables.
18682 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18683 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18684 (SXHASH_REDUCE): New macro.
18685 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18686 Use it instead of discarding useful hash info with large hash values.
18687 (sxhash_float): New function.
18688 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18689 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18690 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18691 Rewrite to use FIXNUM_BITS, as this simplifies things.
18692 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18693 Adjust signatures to match updated version of code.
18694 (consing_since_gc): Now EMACS_INT, since a single hash table can
18695 use more than INT_MAX bytes.
18697 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18699 Make it possible to build with GCC-4.6+ -O2 -flto.

18703 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18705 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18706 Call minibuffer-inactive-mode.
18708 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18710 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18711 Update dependencies.
18713 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18715 * data.c (init_data): Remove code for UTS, this system is not
18718 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18720 Don't force ./temacs to start in terminal mode.
18722 * frame.c (make_initial_frame): Initialize faces in all cases, not
18723 only when CANNOT_DUMP is defined.
18724 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18726 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18728 * dispnew.c (add_window_display_history): Use const for the string
18729 pointer. Remove declaration, not needed.
18731 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18733 Use 'inline', not 'INLINE'.
18734 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18735 * alloc.c, fontset.c (INLINE): Remove.
18736 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18737 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18738 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18739 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18740 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18742 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18744 Make it possible to run ./temacs.
18746 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18747 syms_of_callproc does the same thing. Remove test for
18748 "initialized", do it in the caller.
18749 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18751 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18753 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18754 (read_minibuf): Use get_minibuffer.
18755 (syms_of_minibuf): Use DEFSYM.
18756 (Qmetadata): New var.
18757 * data.c (Qbuffer): Don't make it static.
18758 (syms_of_data): Use DEFSYM.
18760 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18762 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18763 (CCL_CODE_MIN): New macro.
18765 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18767 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18769 * eval.c (Qdebug): Now static.
18770 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18771 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18772 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18774 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18776 * image.c: Various fixes to ImageMagick code comments.
18777 (Fimagemagick_types): Doc fix.
18779 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18781 Minor fixes prompted by GCC 4.6.0 warnings.
18783 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18785 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18786 (x_clipboard_manager_save_all): Move extern decl to ...
18787 * xterm.h: ... here, so that it can be checked for consistency.
18789 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18791 * xselect.c (x_clipboard_manager_save_frame)
18792 (x_clipboard_manager_save_all): New functions.
18793 (Fx_clipboard_manager_save): Lisp function deleted.
18795 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18796 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18798 * xterm.h: Update prototype.
18800 2011-05-28 William Xu <william.xwl@gmail.com>
18802 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18803 exiting (Bug#8239).
18805 2011-05-28 Jim Meyering <meyering@redhat.com>
18807 Avoid a sign-extension bug in crypto_hash_function.
18808 * fns.c (to_uchar): Define.
18809 (crypto_hash_function): Use it to convert some newly-signed
18810 variables to unsigned, to avoid sign-extension bugs. For example,
18811 without this change, (md5 "truc") would evaluate to
18812 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18813 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18814 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18816 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18818 Integer overflow fixes.
18820 * dbusbind.c: Serial number integer overflow fixes.
18821 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18822 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18823 to hold a serial number that is too large for a fixnum.
18824 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18825 Check for serial numbers out of range. Decode any serial number
18826 that was so large that it became a float. (Bug#8722)
18828 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18829 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18830 Use XFASTINT rather than XUINT when numbers are nonnegative.
18831 (xd_append_arg, Fdbus_method_return_internal):
18832 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18833 arguments, check that Lisp number is nonnegative, rather than
18834 silently wrapping negative numbers around. (Bug#8722)
18835 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18838 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18840 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18842 ccl: Add integer overflow checks.
18843 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18844 (IN_INT_RANGE): New macros.
18845 (ccl_driver): Use them to check for integer overflow when
18846 decoding a CCL program. Many of the new checks are whether XINT (x)
18847 fits in int; it doesn't always, on 64-bit hosts. The new version
18848 doesn't catch all possible integer overflows, but it's an
18849 improvement. (Bug#8719)
18851 * alloc.c (make_event_array): Use XINT, not XUINT.
18852 There's no need for unsigned here.
18854 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18855 This follows up to the 2011-05-06 change that substituted uintptr_t
18856 for EMACS_INT. This case wasn't caught back then.
18858 Rework Fformat to avoid integer overflow issues.
18859 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18860 now (part of C89). Include <verify.h>.
18861 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18862 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18863 (Fformat): Avoid the prepass trying to compute sizes; it was only
18864 approximate and thus did not catch overflow reliably. Instead, walk
18865 through the format just once, formatting and computing sizes as we go,
18866 checking for integer overflow at every step, and allocating a larger
18867 buffer as needed. Keep track separately whether the format is
18868 multibyte. Keep only the most-recently calculated precision, rather
18869 than them all. Record whether each argument has been converted to
18870 string. Use EMACS_INT, not int, for byte and char and arg counts.
18871 Support field widths and precisions larger than INT_MAX. Avoid
18872 sprintf's undefined behavior with conversion specifications such as %#d
18873 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18874 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18875 formatting out-of-range floating point numbers with int
18876 formats. (Bug#8668)
18878 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18880 * data.c: Avoid integer truncation in expressions involving floats.
18881 * data.c: Include <intprops.h>.
18882 (arith_driver): When there's an integer overflow in an expression
18883 involving floating point, convert the integers to floating point
18884 so that the resulting value does not suffer from catastrophic
18885 integer truncation. For example, on a 64-bit host (* 4
18886 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18887 Do not rely on undefined behavior after integer overflow.
18889 merge count_size_as_multibyte, parse_str_to_multibyte
18890 * character.c, character.h (count_size_as_multibyte):
18891 Rename from parse_str_to_multibyte; all uses changed.
18892 Check for integer overflow.
18893 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18894 since it's now a duplicate of the other. This is more of
18895 a character than a buffer op, so better that it's in character.c.
18896 * fns.c, print.c: Adjust to above changes.
18898 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18900 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18902 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18904 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18905 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18906 (x_clipboard_manager_save): Now static.
18907 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18909 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18910 (crypto_hash_function): Now static.
18911 Fix pointer signedness problems. Avoid unnecessary initializations.
18913 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18915 * termhooks.h (Vselection_alist): Make it terminal-local.
18917 * terminal.c (create_terminal): Initialize it.
18919 * xselect.c: Support for clipboard managers.
18920 (Vselection_alist): Move to termhooks.h as terminal-local var.
18921 (LOCAL_SELECTION): New macro.
18922 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18923 (symbol_to_x_atom): Remove gratuitous arg.
18924 (x_handle_selection_request, lisp_data_to_selection_data)
18925 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18926 (x_own_selection, x_get_local_selection, x_convert_selection):
18927 New arg, specifying work frame. Use terminal-local Vselection_alist.
18928 (some_frame_on_display): Delete unused function.
18929 (Fx_own_selection_internal, Fx_get_selection_internal)
18930 (Fx_disown_selection_internal, Fx_selection_owner_p)
18931 (Fx_selection_exists_p): New optional frame arg.
18932 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18933 (x_handle_selection_clear): Don't treat other terminals with the
18934 same keyboard specially. Use the terminal-local Vselection_alist.
18935 (x_clear_frame_selections): Use Frun_hook_with_args.
18937 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18939 * xterm.h: Add support for those atoms.
18941 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18943 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18944 (converted_selections, conversion_fail_tag): New global variables.
18945 (x_selection_request_lisp_error): Free the above.
18946 (x_get_local_selection): Remove unnecessary code.
18947 (x_reply_selection_request): Args changed; handle arbitrary array
18948 of converted selections stored in converted_selections.
18949 Separate the XChangeProperty and SelectionNotify steps.
18950 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18951 (x_convert_selection): New function.
18952 (x_handle_selection_event): Simplify.
18953 (x_get_foreign_selection): Don't ignore incoming requests while
18954 waiting for an answer; this will fail when we implement
18955 SAVE_TARGETS, and seems unnecessary anyway.
18956 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18957 (Vx_sent_selection_functions): Doc fix.
18959 2011-05-26 Leo Liu <sdl.web@gmail.com>
18961 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18963 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18965 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18967 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18968 for fringe update if it has periodic bitmap.
18969 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18970 and fringe_bitmap_periodic_p.
18972 * fringe.c (get_fringe_bitmap_data): New function.
18973 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18974 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18975 row. Mark glyph row for fringe update if periodicity changed.
18977 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18978 for fringe update unless it has periodic bitmap.
18980 2011-05-25 Kenichi Handa <handa@m17n.org>
18982 * xdisp.c (get_next_display_element): Set correct it->face_id for
18983 a static composition.
18985 2011-05-24 Leo Liu <sdl.web@gmail.com>
18988 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18990 * fns.c (crypto_hash_function, Fsha1): New function.
18991 (Fmd5): Use crypto_hash_function.

18994 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18996 * gnutls.c: Remove unused macros.
18997 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18998 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18999 Remove macros that are defined and never used.
19000 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19002 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19004 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19005 (Fx_get_selection_internal): Minor cleanup.
19006 (Fx_own_selection_internal): Rename arguments for consistency with
19009 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19011 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19013 2011-05-22 Chong Yidong <cyd@stupidchicken.com>

19024 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19025 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19026 and add some more files.
19028 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19030 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19031 report_file_error introduced by the change from 2011-05-07.
19033 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19035 * systime.h (Time): Define only if emacs is defined.
19036 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19037 where the include path doesn't have X11/X.h by default. See
19038 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19040 2011-05-20 Kenichi Handa <handa@m17n.org>
19042 * composite.c (find_automatic_composition): Fix previous change.
19044 2011-05-20 Glenn Morris <rgm@gnu.org>
19046 * lisp.mk: New file, split from Makefile.in.
19047 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19048 (shortlisp): Remove.
19049 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19051 2011-05-19 Glenn Morris <rgm@gnu.org>
19053 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19054 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19055 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19056 (lisp): Set the order to that of loadup.el.
19057 (shortlisp): Make it a copy of $lisp.
19058 (SOME_MACHINE_LISP): Remove.
19059 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19060 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19062 2011-05-18 Kenichi Handa <handa@m17n.org>
19064 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19065 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19066 (find_automatic_composition): Mostly rewrite for efficiency.
19068 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19070 * makefile.w32-in: Update dependencies.
19072 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19074 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19075 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19077 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19079 Fix some integer overflow issues, such as string length overflow.
19081 * insdel.c (count_size_as_multibyte): Check for string overflow.
19083 * character.c (lisp_string_width): Check for string overflow.
19084 Use EMACS_INT, not int, for string indexes and lengths; in
19085 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19086 the resulting string length overflows an EMACS_INT; instead,
19087 report a string overflow if no precision given. When checking for
19088 precision exhaustion, use a check that cannot possibly have
19089 integer overflow. (Bug#8675)
19090 * character.h (lisp_string_width): Adjust to new signature.
19092 * alloc.c (string_overflow): New function.
19093 (Fmake_string): Use it. This doesn't change behavior, but saves
19094 a few bytes and will simplify future changes.
19095 * character.c (string_escape_byte8): Likewise.
19096 * lisp.h (string_overflow): New decl.
19098 Fixups, following up to the user-interface timestamp change.
19099 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19100 for UI timestamps, instead of unsigned long.
19101 * msdos.c (mouse_get_pos): Likewise.
19102 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19103 * w32gui.h (Time): Define by including "systime.h" rather than by
19104 declaring it ourselves. (Bug#8664)
19106 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19107 * image.c (clear_image_cache): Likewise.
19109 * term.c (term_mouse_position): Don't assume time_t wraparound.
19111 Be more systematic about user-interface timestamps.
19112 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19113 and sometimes 'EMACS_UINT', to represent these timestamps.
19114 This change causes it to use 'Time' uniformly, as that's what X uses.
19115 This makes the code easier to follow, and makes it easier to catch
19116 integer overflow bugs such as Bug#8664.
19117 * frame.c (Fmouse_position, Fmouse_pixel_position):
19118 Use Time, not unsigned long, for user-interface timestamps.
19119 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19120 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19121 * keyboard.h (last_event_timestamp): Likewise.
19122 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19123 * menu.h (xmenu_show): Likewise.
19124 * term.c (term_mouse_position): Likewise.
19125 * termhooks.h (struct input_event.timestamp): Likewise.
19126 (struct terminal.mouse_position_hook): Likewise.
19127 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19128 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19129 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19130 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19131 what it was before.
19132 * menu.h, termhooks.h: Include "systime.h", for Time.
19134 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19135 Don't assume that the difference between two unsigned long values
19136 can fit into an integer. At this point, we know button_down_time
19137 <= event->timestamp, so the difference must be nonnegative, so
19138 there's no need to cast the result if double-click-time is
19139 nonnegative, as it should be; check that it's nonnegative, just in
19140 case. This bug is triggered when events are more than 2**31 ms
19141 apart (about 25 days). (Bug#8664)
19143 * xselect.c (last_event_timestamp): Remove duplicate decl.
19144 (x_own_selection): Remove needless cast to unsigned long.
19146 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19147 that always fit in int. Use a sentinel instead of a counter, to
19148 avoid a temp and to allay GCC's concerns about possible int overflow.
19149 * frame.h (struct frame): Use int for menu_bar_items_used
19150 instead of EMACS_INT, since it always fits in int.
19152 * menu.c (grow_menu_items): Check for int overflow.
19154 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19156 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19157 Before, the code was not consistent. These values cannot exceed
19158 2**31 - 1 so there's no need to make them unsigned.
19159 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19160 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19161 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19163 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19165 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19166 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19167 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19168 presumably because the widths might not match.
19170 * window.c (size_window): Avoid needless test at loop start.
19172 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19174 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19176 2011-05-12 Drew Adams <drew.adams@oracle.com>
19178 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19180 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19182 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19183 `width' to `bar_area_x' and `bar_area_width', respectively.
19184 (x_scroll_run): Take account of fringe background extension.
19186 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19187 Rename local vars `left' and `width' to `bar_area_x' and
19188 `bar_area_width', respectively.
19189 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19190 background extension.
19192 2011-05-10 Jim Meyering <meyering@redhat.com>
19194 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19196 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19198 * image.c (Finit_image_library): Return t for built-in image types,
19199 like pbm and xbm. (Bug#8640)
19201 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19203 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19205 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19207 * w32console.c (Fset_screen_color): Doc fix.
19208 (Fget_screen_color): New function.
19209 (syms_of_ntterm): Defsubr it.
19211 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19212 unlink the temporary file if Fcall_process didn't create it in the
19214 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19215 child process will be redirected to a file specified with `:file'.
19216 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19217 cue to call_process_cleanup not to close that handle.
19219 2011-05-07 Ben Key <bkey76@gmail.com>
19221 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19222 one of two shell specific rules, either bootstrap-temacs-CMD or
19223 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19224 to the previous implementation of the bootstrap-temacs rule.
19225 The bootstrap-temacs-CMD rule is similar to the previous
19226 implementation of the bootstrap-temacs rule except that it
19227 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19230 These changes, along with some changes to nt/configure.bat,
19231 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19232 earlier fix to add support for --cflags and --ldflags options
19233 that include quotes so that it works whether make uses cmd or
19236 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19238 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19239 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19241 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19242 a string. Handle both cases.
19243 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19244 (Fdbus_register_method): Use Qinvalid_function.
19246 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19248 * makefile.w32-in: Update dependencies.
19249 (LISP_H): Add inttypes.h and stdin.h.
19250 (PROCESS_H): Add unistd.h.
19252 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19254 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19255 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19257 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19259 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19261 * term.c (vfatal): Remove stray call to va_end.
19262 It's not needed and the C Standard doesn't allow it here anyway.
19264 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19265 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19267 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19270 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19272 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19274 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19276 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19278 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19280 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19281 * charset.c (Fdefine_charset_internal): Don't initialize
19282 charset.code_space[15]. The value was garbage, on hosts with
19283 32-bit int (Bug#8600).
19285 * lread.c (read_integer): Be more consistent with string-to-number.
19286 Use string_to_number to do the actual conversion; this avoids
19287 rounding errors and fixes some other screwups. Without this fix,
19288 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19289 (digit_to_number): Move earlier, for benefit of read_integer.
19290 Return -1 if the digit is out of range for the base, -2 if it is
19291 not a digit in any supported base. (Bug#8602)
19293 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19295 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19296 to match comment at start of function. This also removes a
19297 GCC warning about overflow in a 32+64-bit port.
19299 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19301 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19302 Reported by Stefan Monnier in
19303 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19304 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19305 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19307 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19308 (EMACS_UINTPTR): Likewise, with uintptr_t.
19310 * lisp.h: Prefer 64-bit EMACS_INT if available.
19311 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19312 on 32-bit hosts that have 64-bit int, so that they can access
19314 However, temporarily disable this change unless the temporary
19315 symbol WIDE_EMACS_INT is defined.
19317 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19319 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19320 This removes an assumption that EMACS_INT and long are the same
19321 width as pointers. The assumption is true for Emacs porting targets
19322 now, but we want to make other targets possible.
19323 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19324 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19325 In the rest of the code, change types of integers that hold casted
19326 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19327 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19328 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19329 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19330 No need to cast type when ORing.
19331 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19332 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19333 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19334 assume EMACS_INT is the same width as char *.
19335 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19336 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19337 Remove no-longer-needed casts.
19338 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19339 (xg_tool_bar_help_callback, xg_make_tool_item):
19340 Use EMACS_INTPTR to hold an integer
19341 that will be cast to void *; this can avoid a GCC warning
19342 if EMACS_INT is not the same width as void *.
19343 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19344 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19345 (current_message_1, set_message_1):
19346 Use a local to convert to proper width without a cast.
19347 * xmenu.c (dialog_selection_callback): Likewise.
19349 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19350 Also, don't assume VALBITS / RAND_BITS is less than 5,
19351 and don't rely on undefined behavior when shifting a 1 left into
19353 * lisp.h (get_random): Change signature to match.
19355 * lread.c (hash_string): Use size_t, not int, for hash computation.
19356 Normally we prefer signed values; but hashing is special, because
19357 it's better to use unsigned division on hash table sizes so that
19358 the remainder is nonnegative. Also, size_t is the natural width
19359 for hashing into memory. The previous code used 'int', which doesn't
19360 retain enough info to hash well into very large tables.
19361 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19363 * dbusbind.c: Don't possibly lose pointer info when converting.
19364 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19365 Use XPNTR rather than XHASH, so that the high-order bits of
19366 the pointer aren't lost when converting through void *.
19368 * eval.c (Fautoload): Don't double-shift a pointer.
19370 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19372 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19374 * gnutls.c (DEF_GNUTLS_FN):
19375 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19377 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19379 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19382 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19384 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19385 New version that can reserve upto 2GB of heap space.
19387 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19389 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19391 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19393 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19394 `gnutls_certificate_set_x509_key_file'.
19396 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19398 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19399 Update dependencies.
19401 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19403 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19404 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19405 Remove unused parameter `fildes'.
19406 * process.c (read_process_output, send_process): Don't pass it.
19408 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19410 Fix previous change: the library cache is defined in w32.c.
19411 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19412 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19414 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19416 Implement dynamic loading of GnuTLS on Windows.
19418 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19419 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19420 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19423 * gnutls.c (Qgnutls_dll): Define.
19424 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19425 (gnutls_*): Declare function pointers.
19426 (init_gnutls_functions): New function to initialize function pointers.
19427 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19428 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19429 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19430 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19431 (emacs_gnutls_write, emacs_gnutls_read)
19432 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19433 (Fgnutls_available_p): New function.
19434 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19435 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19436 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19438 * image.c: Include w32.h.
19439 (Vimage_type_cache): Delete.
19440 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19441 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19442 (w32_delayed_load): Move to w32.c.
19444 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19446 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19447 (w32_delayed_load): Move from image.c. When loading a library, record
19448 its filename in the :loaded-from property of the library id.
19449 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19450 Initialize and staticpro them.
19451 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19453 * process.c: Include lisp.h before w32.h, not after.
19454 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19455 instead of gnutls_record_check_pending.
19457 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19459 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19461 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19462 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19465 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19467 * xterm.c (x_set_frame_alpha): Do not set property on anything
19468 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19470 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19472 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19474 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19476 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19477 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19483 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19484 (Qgnutls_bootprop_callbacks_verify): Make static.
19486 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19488 * callproc.c: Indentation fixup.
19490 * sysdep.c (wait_for_termination_1): Make static.
19491 (wait_for_termination, interruptible_wait_for_termination):
19492 Move after wait_for_termination_1.
19494 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19496 * sysdep.c (interruptible_wait_for_termination): New function
19497 which is like wait_for_termination, but allows keyboard
19500 * callproc.c (Fcall_process): Add (:file "file") as an option for
19502 (Fcall_process_region): Ditto.
19504 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19506 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19507 rather than `XVECTOR (FOO)->size'.
19509 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19510 inttypes.h, as a gnulib replacement is used if it not available in
19513 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19515 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19516 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19517 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19519 * coding.c (coding_alloc_by_realloc): Error out if destination
19520 will grow beyond MOST_POSITIVE_FIXNUM.
19521 (decode_coding_emacs_mule): Abort if there isn't enough place in
19522 charbuf for the composition carryover bytes. Reserve an extra
19523 space for up to 2 characters produced in a loop.
19524 (decode_coding_iso_2022): Abort if there isn't enough place in
19525 charbuf for the composition carryover bytes.
19527 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19529 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19530 aborting when %lld or %lll format is passed.
19531 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19532 %llo or %llx format is passed. (Bug#8545)
19534 * window.c (window_scroll_line_based): Use a marker instead of
19535 simple variables to record original value of point. (Bug#7952)
19537 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19538 produced by %s or %c overflows available buffer space. (Bug#8545)
19540 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19542 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19543 (SIZE_MAX): Move defn after all includes, as they might #define it.
19545 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19547 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19549 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19551 * keyboard.c (Qdelayed_warnings_hook): Define.
19552 (command_loop_1): Run `delayed-warnings-hook'
19553 if Vdelayed_warnings_list is non-nil.
19554 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19555 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19557 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19559 * doprnt.c (doprnt): Don't return value smaller than the buffer
19560 size if the message was truncated. (Bug#8545).
19562 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19564 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19565 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19567 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19569 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19571 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19573 * makefile.w32-in: Update dependencies.
19575 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19577 Improve `doprnt' and its usage. (Bug#8545)
19578 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19579 `format_end'. Remove support for %l as a conversion specifier.
19580 Don't use xrealloc. Improve diagnostics when the %l size modifier
19581 is used. Update the commentary.
19583 * eval.c (verror): Simplify calculation of size_t.
19585 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19588 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19590 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19593 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19595 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19596 This makes this file independent of the recent pseudovector change.
19598 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19600 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19602 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19603 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19604 Remove unused local.
19605 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19607 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19608 GCC 4.6.0 optimizes based on type-based alias analysis.
19609 For example, if b is of type struct buffer * and v of type struct
19610 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19611 != &v->size, and therefore "v->size = 1; b->size = 2; return
19612 v->size;" must therefore return 1. This assumption is incorrect
19613 for Emacs, since it type-puns struct Lisp_Vector * with many other
19614 types. To fix this problem, this patch adds a new type struct
19615 vectorlike_header that documents the constraints on layout of vectors
19616 and pseudovectors, and helps optimizing compilers not get fooled
19617 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19618 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19619 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19621 (XSETPVECTYPE): Rewrite in terms of new macro.
19622 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19623 This is a bit clearer, and further avoids the possibility of
19624 undesirable aliasing.
19625 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19626 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19627 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19628 since Lisp_Subr is a special case (no "next" field).
19629 (ASIZE): Now uses header.size rather than size.
19630 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19631 to avoid the hassle of writing XVECTOR (foo)->header.size.
19632 (struct vectorlike_header): New type.
19633 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19634 object, to help avoid aliasing.
19635 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19636 (SUBRP): Likewise, since Lisp_Subr is a special case.
19637 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19638 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19639 (struct Lisp_Hash_Table): Combine first two members into a single
19640 struct vectorlike_header member. All uses of "size" and "next" members
19641 changed to be "header.size" and "header.next".
19642 * buffer.h (struct buffer): Likewise.
19643 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19644 * frame.h (struct frame): Likewise.
19645 * process.h (struct Lisp_Process): Likewise.
19646 * termhooks.h (struct terminal): Likewise.
19647 * window.c (struct save_window_data, struct saved_window): Likewise.
19648 * window.h (struct window): Likewise.
19649 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19650 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19651 * buffer.c (init_buffer_once): Likewise.
19652 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19654 * process.c (Fformat_network_address): Use local var for size,
19657 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19659 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19660 * data.c (atof): Remove decl; no longer used or needed.
19661 (digit_to_number): Move to lread.c.
19662 (Fstring_to_number): Use new string_to_number function, to be
19663 consistent with how the Lisp reader treats infinities and NaNs.
19664 Do not assume that floating-point numbers represent EMACS_INT
19665 without losing information; this is not true on most 64-bit hosts.
19666 Avoid double-rounding errors, by insisting on integers when
19667 parsing non-base-10 numbers, as the documentation specifies.
19668 * lisp.h (string_to_number): New decl, replacing ...
19669 (isfloat_string): Remove.
19670 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19671 (read1): Do not accept +. and -. as integers; this
19672 appears to have been a coding error. Similarly, do not accept
19673 strings like +-1e0 as floating point numbers. Do not report
19674 overflow for integer overflows unless the base is not 10 which
19675 means we have no simple and reliable way to continue.
19676 Break out the floating-point parsing into a new
19677 function string_to_number, so that Fstring_to_number parses
19678 floating point numbers consistently with the Lisp reader.
19679 (digit_to_number): Move here from data.c. Make it static inline.
19680 (E_CHAR, EXP_INT): Remove, replacing with ...
19681 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19682 (string_to_number): New function, replacing isfloat_string.
19683 This function checks for valid syntax and produces the resulting
19684 Lisp float number too. Rework it so that string-to-number
19685 no longer mishandles examples like "1.0e+". Use strtoumax,
19686 so that overflow for non-base-10 numbers is reported only when
19687 there's no portable and simple way to convert to floating point.
19689 * textprop.c (set_text_properties_1): Rewrite for clarity,
19690 and to avoid GCC warning about integer overflow.
19692 * intervals.h (struct interval): Use EMACS_INT for members
19693 where EMACS_UINT might cause problems. See
19694 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19695 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19696 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19698 (offset_intervals): Tell GCC not to worry about length overflow
19699 when negating a negative length.
19701 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19702 (overrun_check_free): Likewise.
19704 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19705 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19708 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19709 (gnutls_make_error): Rename local to avoid shadowing.
19710 (gnutls_emacs_global_deinit): ifdef out; not used.
19711 (Fgnutls_boot): Use const for pointer to readonly storage.
19712 Comment out unused local. Fix pointer signedness problems.
19714 * lread.c (openp): Don't stuff size_t into an 'int'.
19715 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19716 about possible signed overflow.
19718 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19719 (GDK_KEY_g): Don't define if already defined.
19720 (xg_prepare_tooltip): Avoid pointer signedness problem.
19721 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19723 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19724 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19726 * xfns.c (Fx_window_property): Simplify a bit,
19727 to make a bit faster and to avoid GCC 4.6.0 warning.
19728 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19730 * fns.c (internal_equal): Don't assume size_t fits in int.
19732 * alloc.c (compact_small_strings): Tighten assertion a little.
19734 Replace pEd with more-general pI, and fix some printf arg casts.
19735 * lisp.h (pI): New macro, generalizing old pEd macro to other
19736 conversion specifiers. For example, use "...%"pI"d..." rather
19737 than "...%"pEd"...".
19738 (pEd): Remove. All uses replaced with similar uses of pI.
19739 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19740 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19741 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19742 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19743 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19744 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19745 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19747 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19748 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19749 * print.c (safe_debug_print, print_object): Likewise.
19750 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19752 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19753 avoiding the 0 flag, which is not portable.
19754 * process.c (Fmake_network_process): Use pI to avoid cast.
19755 * region-cache.c (pp_cache): Likewise.
19756 * xdisp.c (decode_mode_spec): Likewise.
19757 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19758 behavior on 64-bit hosts with printf arg.
19759 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19760 (x_stop_queuing_selection_requests): Likewise.
19761 (x_get_window_property): Don't truncate byte count to an 'int'
19764 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19765 here, since it parses constructs like leading '-' and spaces,
19766 which are not wanted; and it overflows with large numbers.
19767 Instead, simply match F[0-9]+, which is what is wanted anyway.
19769 * alloc.c: Remove unportable assumptions about struct layout.
19770 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19771 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19772 (allocate_vectorlike, make_pure_vector): Use the new macros,
19773 plus offsetof, to remove unportable assumptions about struct layout.
19774 These assumptions hold on all porting targets that I know of, but
19775 they are not guaranteed, they're easy to remove, and removing them
19776 makes further changes easier.
19778 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19779 This doesn't fix a bug but makes the code clearer.
19780 (string_overrun_cookie): Now const. Use initializers that
19781 don't formally overflow signed char, to avoid warnings.
19782 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19783 can cause Emacs to crash when string overrun checking is enabled.
19784 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19785 multiple of sizeof (EMACS_INT); it need not be, if
19786 alignof(EMACS_INT) < sizeof (EMACS_INT).
19787 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19789 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19793 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19795 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19796 supposed to be handshaking. (Bug#8556)
19797 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19799 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19801 * lisp.h (Qdebug): List symbol.
19802 * eval.c (Qdebug): Restore global linkage.

19804 (handle_user_signal): Break into debugger when debug-on-event
19805 matches the current signal symbol.
19807 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19809 * alloc.c (check_sblock, check_string_bytes)
19810 (check_string_free_list): Convert to standard C.
19812 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19814 * w32.c (emacs_gnutls_push): Fix typo.
19816 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19818 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19819 "cast to pointer from integer of different size".
19821 Improve doprnt and its use in verror. (Bug#8545)
19822 * doprnt.c (doprnt): Document the set of format control sequences
19823 supported by the function. Use SAFE_ALLOCA instead of always
19826 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19827 is one byte too soon. Don't use xrealloc; instead xfree and
19830 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19832 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19835 * gnutls.c: Renamed global_initialized to
19836 gnutls_global_initialized. Added internals for the
19837 :verify-hostname-error, :verify-error, and :verify-flags
19838 parameters of `gnutls-boot' and documented those parameters in the
19839 docstring. Start callback support.
19840 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19841 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19842 on error. Return error code.
19843 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19844 (emacs_gnutls_read): Likewise.
19845 (Fgnutls_boot): Return handshake error code.

19902 changes in globals.h immediately force recompilation.
19903 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19904 $(CURDIR)/s/ms-w32.h.
19905 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

19909 <char-direction-table>: Deleted.
19911 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19913 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19914 * doprnt.c: Include limits.h.
19915 (SIZE_MAX): New macro.
19916 (doprnt): Return a size_t value. 2nd arg is now size_t.
19917 Many local variables are now size_t instead of int or unsigned.
19918 Improve overflow protection. Support `l' modifier for integer
19919 conversions. Support %l conversion. Don't assume an EMACS_INT
19920 argument for integer conversions and for %c.
19922 * lisp.h (doprnt): Restore prototype.
19924 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19925 $(SRC)/character.h.
19927 * Makefile.in (base_obj): Add back doprnt.o.
19929 * deps.mk (doprnt.o): Add back prerequisites.
19930 (callint.o): Depend on character.h.
19932 * eval.c (internal_lisp_condition_case): Include the handler
19933 representation in the error message.
19934 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19935 when breaking from the loop.
19937 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19939 * callint.c (Fcall_interactively): When displaying error message
19940 about invalid control letter, pass the character's codepoint, not
19941 a pointer to its multibyte form. Improve display of the character
19942 in octal and display also its hex code.
19944 * character.c (char_string): Use %x to display the (unsigned)
19945 codepoint of an invalid character, to avoid displaying a bogus
19948 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19949 `error', not SYMBOL_NAME itself.
19951 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19952 character arguments to `error'.
19954 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19955 to `error' in error message about FINAL_CHAR argument. Make sure
19956 FINAL_CHAR is a character, and use %c when it is passed as
19957 argument to `error'.
19959 2011-04-23 Eli Zaretskii <eliz@gnu.org>

20147 ns_descriptor_to_entity that were caused by using free to
20148 deallocate memory blocks that were allocated by xmalloc (via
20149 xstrdup). This caused Emacs to crash when compiled with

20507 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20508 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20509 exported only to the debugger.
20511 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20512 * atimer.h (run_all_atimers): Remove; not exported.
20514 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20515 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20516 was inaccessible from Lisp.
20517 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20518 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20520 alloc.c: Import and export fewer symbols, and remove unused items.
20521 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20523 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20524 it's not optimized away by whole-program optimization.

20537 (mark_backtrace): Define only if BYTE_MARK_STACK.
20538 * xdisp.c (message_enable_multibyte): Now static.
20540 Declare Lisp_Object Q* variables to be 'static' if not exported.
20541 This makes it easier for human readers (and static analyzers)
20542 to see whether these variables are used from other modules.
20543 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

20553 Remove decls of unexported vars.
20554 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20556 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20558 Make Emacs functions such as Fatom 'static' by default.
20559 This makes it easier for human readers (and static analyzers)
20560 to see whether these functions can be called from other modules.
20561 DEFUN now defines a static function. To make the function external
20562 so that it can be used in other C modules, use the new macro DEFUE.
20563 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20564 (Finit_image_library):

20568 Remove decls, since these functions are now static.
20569 (Funintern, Fget_internal_run_time): New decls, since these functions
20570 were already external.
20572 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20580 Mark functions with DEFUE instead of DEFUN,
20581 if they are used in other modules.
20582 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20583 decls for now-static functions.
20584 * buffer.h (Fdelete_overlay): Remove decl.

20594 * image.c (Finit_image_library): New forward static decl.
20595 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

20620 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20622 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20623 when at ZV. (Bug#8487)
20625 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20627 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20633 * xsettings.c (read_and_apply_settings): Likewise.
20635 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20636 (overrun_check_free): Protoize.
20638 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20640 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20641 since callers should never pass a negative size.
20642 Change the signature to match that of plain 'read' and 'write'; see
20643 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20644 * lisp.h: Update prototypes of emacs_write and emacs_read.
20646 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20648 * xdisp.c (redisplay_window): Don't try to determine the character
20649 position of the scroll margin if the window start point w->startp
20650 is outside the buffer's accessible region. (Bug#8468)
20652 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20654 Fix write-region and its subroutines for buffers > 2GB.
20655 * fileio.c (a_write, e_write): Modify declaration of arguments and
20656 local variables to support buffers larger than 2GB.
20657 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20659 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20660 argument, local variables, and return value.
20662 * lisp.h: Update prototypes of emacs_write and emacs_read.
20664 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20666 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20668 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20670 Fix more problems found by GCC 4.6.0's static checks.
20672 * xdisp.c (vmessage): Use a better test for character truncation.
20674 * charset.c (load_charset_map): <, not <=, for optimization,
20675 and to avoid potential problems with integer overflow.
20676 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20677 * casetab.c (set_identity, shuffle): Likewise.
20678 * editfns.c (Fformat): Likewise.
20679 * syntax.c (skip_chars): Likewise.
20681 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20682 This also lets GCC 4.6.0 generate slightly better loop code.
20684 * callint.c (Fcall_interactively): <, not <=, for optimization.
20685 (Fcall_interactively): Count the number of arguments produced,
20686 not the number of arguments given. This is simpler and lets GCC
20687 4.6.0 generate slightly better code.
20689 * ftfont.c: Distingish more carefully between FcChar8 and char.
20690 The previous code passed unsigned char * to a functions like
20691 strlen and xstrcasecmp that expect char *, which does not
20692 conform to the C standard.
20693 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20694 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20695 char * when the C standard requires it.
20697 * keyboard.c (read_char): Remove unused var.
20699 * eval.c: Port to Windows vsnprintf (Bug#8435).
20700 Include <limits.h>.
20701 (SIZE_MAX): Define if the headers do not.
20702 (verror): Do not give up if vsnprintf returns a negative count.
20703 Instead, grow the buffer. This ports to Windows vsnprintf, which
20704 does not conform to C99. Problem reported by Eli Zaretskii.
20705 Also, simplify the allocation scheme, by avoiding the need for
20706 calling realloc, and removing the ALLOCATED variable.
20708 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20710 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20711 But keep the doprint source code for now, as we might revamp it
20712 and use it again (Bug#8435).
20713 * lisp.h (doprnt): Remove.
20714 * Makefile.in (base_obj): Remove doprnt.o.
20715 * deps.mk (doprnt.o): Remove.
20717 error: Print 32- and 64-bit integers portably (Bug#8435).
20718 Without this change, on typical 64-bit hosts error ("...%d...", N)
20719 was used to print both 32- and 64-bit integers N, which relied on
20720 undefined behavior.
20721 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20722 * lisp.h (error, verror): Mark as printf-like functions.
20723 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20724 Report overflow in size calculations when allocating printf buffer.
20725 Do not truncate output string at its first null byte.
20726 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20727 Truncate the output at a character boundary, since vsnprintf does not
20729 * charset.c (check_iso_charset_parameter): Convert internal
20730 character to string before calling 'error', since %c now has the
20732 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20733 overflow when computing char to be passed to 'error'. Do not
20734 pass Lisp_Object to 'error'; pass the integer instead.
20735 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20736 formatted with plain %d.
20738 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20740 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20742 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20744 * xterm.c (x_catch_errors): Remove duplicate declaration.
20746 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20748 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20750 2011-04-10 Jim Meyering <meyering@redhat.com>
20752 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20753 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20754 return ssize_t not "int", and use size_t as the buffer length.
20755 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20756 * gnutls.h: Update declarations.
20757 * process.c (read_process_output): Use ssize_t, to match.
20758 (send_process): Likewise.
20760 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20762 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20764 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20766 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20767 Use unsigned char, to match FcChar8 type definition.
20769 * xterm.c (handle_one_xevent):
20770 * xmenu.c (create_and_show_popup_menu):
20771 * xselect.c (x_decline_selection_request)
20772 (x_reply_selection_request): Avoid type-punned deref of X events.
20774 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20776 Fix some uses of `int' instead of EMACS_INT.
20777 * search.c (string_match_1, fast_string_match)
20778 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20779 (scan_buffer, find_next_newline_no_quit)
20780 (find_before_next_newline, search_command, Freplace_match)
20781 (Fmatch_data): Make some `int' variables be EMACS_INT.
20783 * xdisp.c (display_count_lines): 3rd argument and return value now
20784 EMACS_INT. All callers changed.
20785 (pint2hrstr): Last argument is now EMACS_INT.
20787 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20788 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20789 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20800 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20801 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20803 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20804 (encode_invocation_designation): Last argument P_NCHARS is now
20806 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20807 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20809 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20812 * ccl.c (Fccl_execute_on_string): Declare some variables
20815 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20817 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20819 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20821 * process.c (Fformat_network_address): Doc fix.
20823 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20825 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20827 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20829 * keyboard.c (read_char): Call Lisp function help-form-show,
20830 instead of using internal_with_output_to_temp_buffer.
20831 (Qhelp_form_show): New var.
20832 (syms_of_keyboard): Use DEFSYM macro.
20834 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20841 (list_processes_1): Delete.
20843 2011-04-06 Eli Zaretskii <eliz@gnu.org>

20847 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20849 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20851 Fix more problems found by GCC 4.6.0's static checks.
20853 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20855 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20857 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20859 * xdisp.c (vmessage): Mark as a printf-like function.
20861 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20865 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20866 printf-like functions.
20867 (tiff_load): Add casts to remove these marks before passing them
20868 to system-supplied API.
20870 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20872 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20873 This avoids several warnings with gcc -Wstrict-overflow.
20874 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20875 directly, rather than having caller test rule sign. This avoids
20876 some unnecessary tests.
20877 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20878 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20879 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20881 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20882 (xfont_open): Avoid unnecessary tests.
20884 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20886 * composite.h, composite.c (composition_gstring_put_cache):
20887 Use EMACS_INT, not int, for length.
20889 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20890 breaking out part of COMPOSITION_DECODE_RULE.
20891 (COMPOSITION_DECODE_RULE): Use it.
20892 * composite.c (get_composition_id): Remove unused local vars,
20893 by using the new macro.
20895 * textprop.c (set_text_properties_1): Change while to do-while,
20896 since the condition is always true at first.
20898 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20899 (interval_deletion_adjustment): Return unsigned value.
20902 * process.c (list_processes_1, create_pty, read_process_output):
20903 (exec_sentinel): Remove vars that were set but not used.
20904 (create_pty): Remove unnecessary "volatile"s.
20905 (Fnetwork_interface_info): Avoid possibility of int overflow.
20906 (read_process_output): Do adaptive read buffering even if carryover.
20907 (read_process_output): Simplify nbytes computation if buffered.

20911 * syntax.c (scan_words): Remove var that was set but not used.
20912 (update_syntax_table): Use unsigned instead of int.
20914 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20915 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20916 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20918 * print.c (print_error_message): Avoid int overflow.
20920 * font.c (font_list_entities): Redo for clarity,
20921 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20923 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20924 (font_score): Avoid potential overflow in diff calculation.
20926 * fns.c (substring_both): Remove var that is set but not used.
20927 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20929 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20931 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20932 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20933 can always succeed if overflow has undefined behavior.
20935 * search.c (boyer_moore, wordify): Remove vars set but not used.
20936 (wordify): Omit three unnecessary tests.
20938 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20939 All callers changed. This avoids the need for an unused var.
20941 * casefiddle.c (casify_region): Remove var that is set but not used.
20943 * dired.c (file_name_completion): Remove var that is set but not used.
20945 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20947 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20948 (Finsert_file_contents): Remove unnecessary code checking fd.
20950 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20951 Check for integer overflow on size calculations.
20953 * buffer.c (Fprevious_overlay_change): Remove var that is set
20956 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20957 Remove vars that are set but not used.
20958 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20959 (timer_check_2): Mark vars as initialized.
20961 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20963 * image.c (lookup_image): Remove var that is set but not used.
20964 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20966 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20967 that are set but not used.
20969 * xfns.c (make_invisible_cursor): Don't return garbage
20970 if XCreateBitmapFromData fails (Bug#8410).
20972 * xselect.c (x_get_local_selection, x_handle_property_notify):
20973 Remove vars that are set but not used.
20975 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20976 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20978 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20979 Remove var that is set but not used.
20980 (scroll_bar_windows_size): Now size_t, not int.
20981 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20982 Check for overflow.
20984 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20985 (map_tty_color) [!defined MSDOS]: Likewise.
20987 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20989 * coding.c: Remove vars that are set but not used.
20990 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20991 All callers changed.
20992 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20993 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20994 (decode_coding_charset): Remove vars that are set but not used.
20996 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20997 that is set but not used.
20999 * print.c (print_object): Remove var that is set but not used.
21001 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21002 The gnulib version avoids calling malloc in the usual case,
21003 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21004 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21005 * filelock.c (current_lock_owner): Likewise.
21006 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21007 * sysdep.c: Include allocator.h, careadlinkat.h.
21008 (emacs_no_realloc_allocator): New static constant.
21009 (emacs_readlink): New function.
21010 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21011 ../lib/careadlinkat.h.
21013 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21015 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21016 first non-nil return value).
21018 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21020 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21021 if not defined (Bug#8403).
21023 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21025 * xdisp.c (display_count_lines): Remove parameter `start',
21026 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21027 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21028 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21030 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21031 and thereabouts. All callers changed.
21032 (get_per_char_metric): Remove parameter `f', unused since
21033 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21035 2011-04-02 Jim Meyering <meyering@redhat.com>
21037 do not dereference NULL upon failed strdup
21038 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21039 (ns_get_family): Likewise.
21041 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21043 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21045 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21047 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21050 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21052 Add lexical binding.
21054 * window.c (Ftemp_output_buffer_show): New fun.
21055 (Fsave_window_excursion):
21056 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21058 * lread.c (lisp_file_lexically_bound_p): New function.
21059 (Fload): Bind Qlexical_binding.
21060 (readevalloop): Remove `evalfun' arg.
21061 Bind Qinternal_interpreter_environment.
21062 (Feval_buffer): Bind Qlexical_binding.
21063 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21065 (syms_of_lread): Declare `lexical-binding'.
21067 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21069 * keyboard.c (eval_dyn): New fun.
21070 (menu_item_eval_property): Use it.
21072 * image.c (parse_image_spec): Use Ffunctionp.
21074 * fns.c (concat, mapcar1): Accept byte-code-functions.
21076 * eval.c (Fsetq): Handle lexical vars.
21077 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21078 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21079 (FletX, Flet): Obey lexical binding.
21080 (Fcommandp): Handle closures.
21081 (Feval): New `lexical' arg.
21082 (eval_sub): New function extracted from Feval. Use it almost
21083 everywhere where Feval was used. Look up vars in lexical env.
21085 (Ffunctionp): Move from subr.el.
21086 (Ffuncall): Handle closures.
21087 (apply_lambda): Remove `eval_flags'.
21088 (funcall_lambda): Handle closures and new byte-code-functions.
21089 (Fspecial_variable_p): New function.
21090 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21091 but without exporting it to Lisp.
21093 * doc.c (Fdocumentation, store_function_docstring):
21094 * data.c (Finteractive_form): Handle closures.
21096 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21099 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21101 (exec_byte_code): New function extracted from Fbyte_code to handle new
21102 calling convention for byte-code-functions. Add new byte-codes.
21104 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21106 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21108 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21110 * xdisp.c (redisplay_internal): Fix prototype.
21112 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21114 * xdisp.c (SCROLL_LIMIT): New macro.
21115 (try_scrolling): Use it when setting scroll_limit.
21116 Limit scrolling to 100 screen lines.
21117 (redisplay_window): Even when falling back on "recentering",
21118 position point in the window according to scroll-conservatively,
21119 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21121 (try_scrolling): When point is above the window, allow searching
21122 as far as scroll_max, or one screenful, to compute vertical
21123 distance from PT to the scroll margin position. This prevents
21124 try_scrolling from unnecessarily failing when
21125 scroll-conservatively is set to a value slightly larger than the
21126 window height. Clean up the case of PT below the margin at bottom
21127 of window: scroll_max can no longer be INT_MAX. When aggressive
21128 scrolling is in use, don't let point enter the opposite scroll
21129 margin as result of the scroll.
21130 (syms_of_xdisp) <scroll-conservatively>: Document the
21131 threshold of 100 lines for never-recentering scrolling.
21133 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21135 * dispextern.h (move_it_by_lines):
21136 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

21138 (message_log_check_duplicate): Remove parameters `prev_bol' and
21139 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21140 (redisplay_internal): Remove parameter `preserve_echo_area',
21141 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21143 * indent.c (Fvertical_motion):
21144 * window.c (window_scroll_pixel_based, Frecenter):
21145 Don't pass `need_y_p' to `move_it_by_lines'.
21147 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21149 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21150 steal a few bits to be more compact.
21151 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21152 Remove unneeded casts.
21154 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21156 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21158 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21159 binding" message (bug#7967).
21161 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21163 Fix more problems found by GCC 4.6.0's static checks.
21165 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21166 Remove unused local var.
21168 * editfns.c (Fmessage_box): Remove unused local var.
21170 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21171 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21172 Omit unused local vars.
21173 * window.c (shrink_windows): Omit unused local var.
21174 * menu.c (digest_single_submenu): Omit unused local var.
21175 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21176 Omit unused local var.
21178 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21179 Don't assume string length fits in int.
21180 (keyremap_step, read_key_sequence): Use size_t for sizes.
21181 (read_key_sequence): Don't check last_real_key_start redundantly.
21183 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21184 instead of alloca (Bug#8344).
21186 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21187 (Fbacktrace_frame): Don't assume nframes fits in int.
21189 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21191 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21194 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21196 * cm.c (calccost): Turn while-do into do-while, for clarity.
21198 * keyboard.c (syms_of_keyboard): Use the same style as later
21199 in this function when indexing through an array. This also
21200 works around GCC bug 48267.
21202 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21204 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21206 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21207 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21209 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21210 This avoids undefined behavior on integer overflow, and is a bit
21211 more convenient anyway since it is compared to a size_t variable.
21213 Variadic C functions now count arguments with size_t, not int.
21214 This avoids an unnecessary limitation on 64-bit machines, which
21215 caused (substring ...) to crash on large vectors (Bug#8344).
21216 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21217 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21225 * fns.c (concat): Likewise.
21226 * frame.c (x_set_frame_parameters): Likewise.
21227 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21228 0 if not found, not -1. All callers changed.
21230 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21231 (stack_copy_size): Now size_t, not int.
21232 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21234 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21236 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21237 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21238 All callers changed.
21240 * lisp.h (multibyte_char_to_unibyte):
21241 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21242 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21246 * keymap.c (push_key_description):
21247 * search.c (Freplace_match):
21248 * xdisp.c (message_dolog, set_message_1): All callers changed.
21250 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21252 * keyboard.c (safe_run_hook_funcall): New function.
21253 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21254 don't set the hook to nil, but remove the offending function instead.
21255 (Qcommand_hook_internal): Remove, unused.
21256 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21257 Vcommand_hook_internal.
21259 * eval.c (enum run_hooks_condition): Remove.
21260 (funcall_nil, funcall_not): New functions.
21261 (run_hook_with_args): Call each function through a `funcall' argument.
21262 Remove `cond' argument, now redundant.
21263 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21264 (Frun_hook_with_args_until_failure): Adjust accordingly.
21265 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

21271 * print.c (strout): Remove parameter `multibyte', unused since
21272 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21274 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21275 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21276 All callers changed.
21278 * w32.c (_wsa_errlist): Use braces for struct initializers.
21280 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21281 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21282 All callers changed.

21436 * callint.c (Fcall_interactively):
21437 * buffer.c (Fkill_all_local_variables):
21438 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21440 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21441 unconditionally since it does the check itself.
21443 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21445 Fix more problems found by GCC 4.5.2's static checks.
21447 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21448 the first time through the loop, since we know p0 < p1 then.
21449 This also avoids a gcc -Wstrict-overflow warning.
21451 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21452 leading to a memory leak, possible in functions like
21453 load_charset_map_from_file that can allocate an unbounded number
21454 of objects (Bug#8318).
21456 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21457 that could (at least in theory) be that large.
21459 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21460 This is less likely to overflow, and avoids undefined behavior if
21461 overflow does occur. All callers changed. Use strtoul to scan
21462 for the unsigned long integer.
21463 (pint2hrstr): Simplify and tune code slightly.
21464 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21474 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21477 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21479 * process.c (Fmake_network_process): Use socklen_t, not int,
21480 where POSIX says socklen_t is required in portable programs.
21481 This fixes a porting bug on hosts like 64-bit HP-UX, where
21482 socklen_t is wider than int (Bug#8277).
21483 (Fmake_network_process, server_accept_connection):
21484 (wait_reading_process_output, read_process_output):
21487 * process.c: Rename or move locals to avoid shadowing.

21497 Make tparam.h and terminfo.c consistent.
21498 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21499 Include tparam.h instead, since it declares them.
21500 * cm.h (PC): Remove extern decl; tparam.h now does this.
21501 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21502 * terminfo.c: Include tparam.h, to check interfaces.
21503 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21504 (tparam): Adjust signature to match interface in tparam.h;
21505 this removes some undefined behavior. Check that outstring and len
21506 are zero, which they always are with Emacs.
21507 * tparam.h (PC, BC, UP): New extern decls.
21509 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21510 (xftfont_open): Rename locals to avoid shadowing.
21512 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

21527 (find_automatic_composition, composition_adjust_point): Likewise.
21528 (composition_update_it): Mark var as initialized.
21529 (find_automatic_composition): Mark vars as initialized,
21530 with a FIXME (Bug#8290).

21534 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21535 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21536 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21537 to avoid shadowing.
21539 * textprop.c (property_change_between_p): Remove; unused.
21541 * intervals.c (interval_start_pos): Now static.
21543 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21549 Fix pointer signedness.
21550 (alsa_choose_format): Remove unused local var.
21551 (wav_play): Initialize a variable to 0, to prevent undefined
21552 behavior (Bug#8278).
21554 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21556 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21558 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21559 clobbering (Bug#8298).
21560 * sysdep.c (sys_subshell): Likewise.
21561 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21563 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21564 This should get cleaned up, so that child_setup has the
21565 same signature on all platforms.
21567 * callproc.c (call_process_cleanup): Now static.
21568 (relocate_fd): Rename locals to avoid shadowing.
21570 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21572 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21573 not to be necessary, and produces flickering.
21575 2011-03-20 Glenn Morris <rgm@gnu.org>
21577 * config.in: Remove file.
21579 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21581 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21582 are now in src/globals.h.
21583 (syms_of_minibuf): Remove spurious & from previous change.

21623 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
21624 Define only if needed.
21626 * unexelf.c (unexec): Name an expression,
21627 to avoid gcc -Wbad-function-cast warning.
21628 Use a different way to cause a compilation error if anyone uses
21629 n rather than nn, a way that does not involve shadowing.
21630 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21632 * deps.mk (unexalpha.o): Remove; unused.
21634 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21709 ENABLE_CHECKING is not defined.
21711 * data.c (Findirect_variable): Name an expression, to avoid
21712 gcc -Wbad-function-cast warning.

21753 which gcc can warn about.
21754 (regex_compile, re_match_2_internal): Mark locals as initialized.
21755 (RETALLOC_IF): Define only if needed.
21756 (WORDCHAR_P): Likewise. This one is never needed, but is used
21757 only in a comment talking about a compiler bug, so put inside
21758 the #if 0 of that comment.
21759 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21760 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21763 * search.c (boyer_moore): Rename locals to avoid shadowing.

21787 New macros, so that the caller can use some names other than
21788 gcpro1, gcpro2, etc.
21789 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21791 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21792 argument, for consistency with GCPRO2_VAR, etc: it is now the

21796 Rename locals to avoid shadowing.
21798 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21799 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21800 dired.c's scmp function, had undefined behavior.
21801 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21802 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21803 * buffer.h: ... to here, because these macros use current_buffer,
21804 and the new implementation with inline functions needs to have
21805 current_buffer in scope now, rather than later when the macros
21807 (downcase, upcase1): New static inline functions.
21808 (DOWNCASE, UPCASE1): Reimplement using these functions.
21809 This avoids undefined behavior in expressions like
21810 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21811 from race conditions in accessing the global variables
21812 case_temp1 and case_temp2.
21813 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

21821 * fileio.c (file_name_as_directory, directory_file_name):

21824 (file_name_as_directory): Use const pointers when appropriate.
21825 (Fexpand_file_name): Likewise. In particular, newdir might
21826 point at constant storage, so make it a const pointer.

21830 (Fset_file_times, Finsert_file_contents, auto_save_error):

21835 to avoid shadowing.
21837 * marker.c (bytepos_to_charpos): Remove; unused.
21839 * lisp.h (verify_bytepos, count_markers): New decls,
21840 so that gcc does not warn that these functions aren't declared.
21842 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21843 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21844 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21845 (copy_text): Remove unused local var.

21848 (lock_file_1): Rename local to avoid shadowing.
21850 * buffer.c (fix_overlays_before): Mark locals as initialized.
21851 (fix_start_end_in_overlays): Likewise. This function should be
21852 simplified by using pointers-to-pointers, but that's a different
21854 (switch_to_buffer_1): Now static.
21855 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21856 (report_overlay_modification): Rename locals to avoid shadowing.

21859 Fix pointer signedness issue.
21860 (sys_subshell): Mark local as volatile if checking for lint,
21861 to suppress a gcc -Wclobbered warning that does not seem to be right.
21862 (MAXPATHLEN): Define only if needed.
21864 * process.c (serial_open, serial_configure): Move decls from here ...
21865 * systty.h: ... to here, so that they can be checked.
21867 * fns.c (get_random, seed_random): Move extern decls from here ...
21868 * lisp.h: ... to here, so that they can be checked.
21870 * sysdep.c (reset_io): Now static.
21871 (wait_for_termination_signal): Remove; unused.
21873 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21878 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21879 (describe_map_tree):
21880 Rename locals to avoid shadowing.
21882 * keyboard.c: Declare functions static if they are not used elsewhere.
