15 * w32unsubscribe.c (uniscribe_shape):
16 * window.c (Fcurrent_window_configuration):
17 * xfaces.c (Fx_family_fonts):
18 * xselect.c (selection_data_to_lisp_data): Use it.
20 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
22 * coding.c (Fdefine_coding_system_internal): Use AREF where
23 argument is known to be a vector.
24 * fns.c (Flocale_info): Likewise for ASET.
25 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
26 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
28 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
30 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
33 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
34 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
35 updateCollectionBehaviour.
37 * nsterm.m (NEW_STYLE_FS): Remove.
38 (ns_last_use_native_fullscreen): New variable.
39 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
40 (x_set_window_size): Do not take title bar and tool bar into account
41 if isFullscreen returns YES.
42 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
43 (check_native_fs): New function.
44 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
45 (ns_term_init): Remove NEW_STYLE_FS.
46 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
47 and tool bar if isFullscreen returns NO.
48 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
49 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
51 (window:willUseFullScreenPresentationOptions:): New method.
52 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
53 Hide toolbar if not enabled (Bug#13444).
54 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
55 Restore tool bar if enabled, hide it otherwise (Bug#13444).
56 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
57 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
58 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
59 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
60 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
61 (syms_of_nsterm): Add ns-use-native-fullscreen.
63 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
65 * fileio.c (Qchoose_write_coding_system): Now static.
67 2013-02-04 Eli Zaretskii <eliz@gnu.org>
69 * xdisp.c (window_buffer_changed): region_showing can be negative,
70 which still means region is being displayed.
71 (redisplay_internal): Resurrect code that forced redisplay of the
72 whole window when showing region and the mark has changed. Record
73 the new mark position to allow redisplay optimizations.
74 (display_line): If it->region_beg_charpos is non-zero, set the
75 window's region_showing member to -1. (Bug#13623) (Bug#13626)
77 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
78 not bitfield of 1 bit.
80 2013-02-03 Daniel Colascione <dancol@dancol.org>
82 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
83 daemon mode works on cygw32 when Emacs is installed and not just
86 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
88 Avoid file time stamp bug on MS-Windows (Bug#13149).
89 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
90 as FAT32 doesn't update time stamps when truncating them.
91 Also, check that a file time stamp is not a multiple of 100 ns;
92 this should catch all instances of the problem on MS-Windows,
93 as its native file system resolution is 100 ns or worse, and
94 checking for a non-multiple of 100 ns should impose only a small
95 overhead on systems with ns resolution.
97 2013-02-02 Eli Zaretskii <eliz@gnu.org>
99 Avoid encoding file names on MS-Windows when they need to be run
100 through dostounix_filename.
101 * w32.c (normalize_filename): Accept an additional argument
102 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
103 downcase it even if w32-downcase-file-names is non-nil.
104 (dostounix_filename): Accept an additional argument MULTIBYTE and
105 pass it to normalize_filename.
106 (emacs_root_dir): Adjust.
108 * msdos.h (dostounix_filename): Adjust prototype.
110 * w32.h (dostounix_filename): Adjust prototype.
112 * msdos.c (dostounix_filename): Accept an additional argument and
114 (init_environment): Adjust callers of dostounix_filename.
116 * fileio.c (Ffile_name_directory, file_name_as_directory)
117 (directory_file_name, Fexpand_file_name)
118 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
120 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
122 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
123 variables, as egetenv is case-insensitive for DOS_NT.
125 * dired.c (file_name_completion): Don't call Fdirectory_file_name
126 with an encoded file name.
128 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
129 calls to dostounix_filename.
131 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
133 * unexw32.c (unexec): Adjust call to dostounix_filename.
135 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
137 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
140 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
143 * callproc.c (Fcall_process): Make sure program name in PATH and
144 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
145 is passed to exec/spawnve, which fails unless the file-name
148 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
149 even if w32-quote-process-args is nil.
151 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
153 Fix timestamp bug when write-region appends nothing (Bug#13149).
154 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
155 the file's time stamp doesn't change if Emacs happens to write nothing
156 to the file, and on a buggy file system this could cause Emacs to
157 incorrectly infer that the file system doesn't have the bug.
158 Avoid this problem by inhibiting the inference in this case.
160 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
162 * window.h (struct window): Convert base_line_number, base_line_pos
163 and column_number_displayed members from Lisp_Object to ptrdiff_t.
164 Convert region_showing member from Lisp_Object to bitfield.
165 Remove sequence_number member. Adjust comments.
166 * window.c (sequence_number): Remove.
167 (make_window): Initialize column_number_displayed.
168 * print.c (print_object): Follow the printed representation of
169 frames and print window pointer to distinguish between windows.
170 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
171 * xdisp.c (wset_base_line_number, wset_base_line_pos)
172 (wset_column_number_displayed, wset_region_showing): Remove.
173 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
174 (try_scrolling, try_cursor_movement, redisplay_window)
175 (try_window_reusing_current_matrix, try_window_id, display_line)
176 (display_mode_lines, decode_mode_spec): Adjust users.
177 * .gdbinit (pwinx): Do not print sequence_number.
179 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
181 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
182 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
183 * dired.c: Include <fcntl.h>.
184 (open_directory): New function, which uses open and fdopendir
185 rather than opendir. DOS_NT platforms still use opendir, though.
186 (directory_files_internal, file_name_completion): Use it.
187 (file_attributes): New function, with most of the old Ffile_attributes.
188 (directory_files_internal, Ffile_attributes): Use it.
189 (file_attributes, file_name_completion_stat): First arg is now fd,
190 not dir name. All uses changed. Use fstatat rather than lstat +
192 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
193 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
194 (emacs_readlinkat): New function, with much of the old
195 Ffile_symlink_p, but with an fd argument for speed.
196 It uses readlinkat rather than careadlinkatcwd, so that it
197 need not assume the working directory.
198 (Ffile_symlink_p): Use it.
199 * filelock.c (current_lock_owner): Use emacs_readlinkat
200 rather than emacs_readlink.
201 * lisp.h (emacs_readlinkat): New decl.
202 (READLINK_BUFSIZE, emacs_readlink): Remove.
203 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
204 (emacs_norealloc_allocator, emacs_readlink): Remove.
205 This stuff is moved to fileio.c.
206 * w32.c (fstatat, readlinkat): New functions.
207 (careadlinkat): Don't check that fd == AT_FDCWD.
208 (careadlinkatcwd): Remove; no longer needed.
210 2013-01-31 Glenn Morris <rgm@gnu.org>
212 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
213 (Fwrite_region): Update for new choose_write_coding_system args.
214 Move the last piece of choose_write_coding_system here. (Bug#13522)
215 (syms_of_fileio): Add choose-write-coding-system.
217 2013-01-30 Eli Zaretskii <eliz@gnu.org>
219 * w32.c (sys_open): Zero out the flags for the new file descriptor.
220 (sys_close): Zero out the flags for the file descriptor before
221 closing it. (Bug#13546)
223 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
224 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
225 CharNextExA and CharPrevExA to iterate over file names encoded in
228 * w32.c (w32_get_long_filename, init_environment, readlink):
229 Support file names encoded in DBCS codepages.
230 (readlink): Use the current file-name-coding-system, not the ANSI
231 codepage, to decode and handle targets of symlinks.
233 2013-01-28 Eli Zaretskii <eliz@gnu.org>
235 * w32.c (opendir): Now accepts a 'const char *'.
237 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
239 Remove obsolete redisplay code. See the discussion at
240 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
241 * dispnew.c (preemption_period, preemption_next_check): Remove.
242 (Vredisplay_preemption_period): Likewise.
243 (update_frame, update_single_window, update_window, update_frame_1):
244 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
245 used, following the 2012-06-22 change.
247 2013-01-25 Eli Zaretskii <eliz@gnu.org>
249 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
251 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
253 * font.c (num_fonts): Remove the leftover from old
254 debugging code. Adjust comment style here and there.
255 * insdel.c (insert_1): Remove.
256 * lisp.h (insert_1): Remove prototype.
257 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
259 2013-01-25 Eli Zaretskii <eliz@gnu.org>
261 * w32.c (max_filename_mbslen): New function.
262 (normalize_filename, readdir): Use it to detect locales where ANSI
263 encoding of file names uses a double-byte character set (DBCS).
264 If a DBCS encoding is used, advance by characters using
265 CharNextExA, instead of incrementing a 'char *' pointer. Use
266 _mbslwr instead of _strlwr. (Bug#13515)
268 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
269 request of memory reservation to 1.7GB. (Bug#13065)
271 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
273 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
274 at check_extra_latin label. (Bug#13505)
276 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
278 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
279 Avoid redundant calls to strlen.
281 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
283 Drop async_visible and async_iconified fields of struct frame.
284 This is possible because async input is gone; for details, see
285 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
286 * frame.h (struct frame): Remove async_visible and async_iconified
287 members, convert garbaged to unsigned bitfield. Adjust comments.
288 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
289 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
290 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
291 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
292 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
294 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
295 properly. Likewise for obscured.
297 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
300 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
302 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
304 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
305 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
307 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
309 * xdisp.c (message2, message2_nolog): Remove functions.
310 (message3, message3_nolog): Extract nbytes and multibyteness directly
311 from the string. Change all callers.
312 (message3_nolog): Don't set message_enable_multibyte since set_message
313 will reset it anyway.
314 (message1, message1_nolog): Use message3.
315 (vmessage): Use a stack allocated buffer rather than f->message_buf.
316 (with_echo_area_buffer): Remove last two arguments. Update all callers.
317 (set_message): Drop all but the second arg, which has to be a string.
318 (set_message_1): Simplify now that we know that a1 is NULL and the
319 second arg is a string.
320 * frame.h (struct frame): Remove `message_buf' field.
321 Use glyphs_initialized_p instead.
322 (FRAME_MESSAGE_BUF): Remove macro.
323 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
324 * lisp.h (message2, message2_nolog): Remove declarations.
325 (message3, message3_nolog): Update declarations.
326 * keyboard.c (read_char_minibuf_menu_text)
327 (read_char_minibuf_menu_width): Remove vars.
328 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
329 to correctly handle multibyte strings.
330 * frame.c (delete_frame): Don't free message_buf any more.
331 * editfns.c (message_text, message_length): Remove vars.
332 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
333 * fileio.c (auto_save_error): Use message3 instead of message2.
334 * dispnew.c (adjust_frame_message_buffer): Remove function.
336 2013-01-23 Eli Zaretskii <eliz@gnu.org>
338 * w32term.c (w32fullscreen_hook): Account correctly for the screen
339 real estate used for the tool bar and the menu bar.
341 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
343 * insdel.c (prepare_to_modify_buffer): Force redisplay if
344 hidden buffer is prepared to modification (Bug#13164).
346 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
348 * window.h (struct window): Change window_end_valid member from
349 Lisp_Object to a bitfield. Adjust comments.
350 (wset_window_end_valid): Remove.
351 * window.c (adjust_window_count): Clear window_end_valid.
352 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
353 (Fwindow_line_height, set_window_buffer, Frecenter)
354 (Fsplit_window_internal, Fdelete_other_windows_internal)
355 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
356 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
357 * xdisp.c (check_window_end, reconsider_clip_changes)
358 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
359 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
360 (find_first_unchanged_at_end_row, try_window_id): Likewise.
362 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
364 * xdisp.c (mark_window_display_accurate): Simplify the loop
365 assuming that the only one of vchild, hchild or buffer window
366 slots is non-nil. Call mark_window_display_accurate_1 for
367 the leaf windows only.
368 (mark_window_display_accurate_1): Always assume leaf window.
371 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
373 * emacs.c (Qkill_emacs_hook): Now static.
375 * fileio.c (Finsert_file_contents): Simplify.
376 Remove unnecessary assignments and tests.
378 2013-01-21 Eli Zaretskii <eliz@gnu.org>
380 * w32.c (acl_set_file): Don't test for errors unless
381 set_file_security returns FALSE. Avoids spurious errors when
384 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
386 * fileio.c (Finsert_file_contents): Revert code introduced at
387 2013-01-18 in favor of the simpler and generally better fix.
388 Save stack space by removing 'buffer' and reusing 'read_buf'
391 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
393 * lisp.h (eabs): Define unconditionally (Bug#13419).
394 The old "#if !defined (eabs)" was an unnecessary revenant of back
395 when this macro was called "abs". Document 'eabs' better.
397 2013-01-19 Glenn Morris <rgm@gnu.org>
399 * fns.c (Frandom): Doc fix.
401 2013-01-19 Eli Zaretskii <eliz@gnu.org>
403 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
404 segfault when there are lots of overlays.
406 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
407 when there are lots of overlays. See
408 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
409 for the details and a way to reproduce.
411 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
413 * fileio.c: Use O_APPEND to append.
414 This corresponds better to the natural interpretation of "append",
415 and avoids the need to open the output file twice, or to invoke
416 lseek when APPEND is neither nil nor a number.
417 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
418 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
419 file possibly twice, and lseeking to its end; this avoids the
420 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
421 at the same time: the combination is never needed and apparently
422 it doesn't work with DOS_NT.
424 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
425 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
427 Allow floating-point file offsets.
428 Problem reported by Vitalie Spinu in
429 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
430 * fileio.c (emacs_lseek): Remove.
431 (file_offset): New function.
432 (Finsert_file_contents, Fwrite_region): Use it.
434 2013-01-19 Chong Yidong <cyd@gnu.org>
436 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
437 aborting on Fsignal (Bug#13289).
439 2013-01-19 Eli Zaretskii <eliz@gnu.org>
441 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
442 set_file_security as failure due to insufficient privileges.
443 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
444 (fstat): Return owner and group like 'stat' and 'lstat' do.
446 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
448 Work around bug in CIFS and vboxsf file systems (Bug#13149).
449 The bug was observed on Ubuntu operating inside a virtual machine,
450 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
451 The workaround introduces a race condition on non-buggy hosts,
452 but it's an unlikely race and anyway there's a nearly identical
453 nearby race that can't be fixed.
454 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
456 (Fwrite_region): Test for file system time stamp bug.
457 (init_fileio): New function.
458 * lisp.h (init_fileio): Declare it.
459 * emacs.c (main): Call it.
461 * fileio.c (Finsert_file_contents): Simplify new diagnostic
462 and make it more consistent with other stat-failure diagnostics.
464 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
466 Fix crash when inserting data from non-regular files. See
467 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
468 for the error description produced by valgrind.
469 * fileio.c (read_non_regular): Rename to read_contents.
470 Free Lisp_Save_Value object used to pass parameters.
471 (read_non_regular_quit): Rename to read_contents_quit.
472 (Finsert_file_contents): Redesign internal file reading loop to adjust
473 gap and end positions after each read and so help make_gap to work
474 properly. Do not signal an I/O error too early and so do not leave
475 not yet decoded characters in a buffer, which was the reason of
476 redisplay crash. Use list2 to build return value. Adjust comments.
478 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
480 Close a race when statting and reading files (Bug#13149).
481 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
482 This avoids a race if the file is renamed between stat and open.
483 This race is not the problem originally noted in Bug#13149;
484 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
486 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

583 * editfns.c (save_excursion_save): Pack everything within
584 Lisp_Save_Value and so avoid xmalloc.
585 (save_excursion_restore): Adjust to match new layout. Use free_misc
586 because we do not allocate extra memory any more. Add eassert.
587 * print.c (print_object): New code to print Lisp_Save_Value. Do not
588 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

674 switches from 'signal' to 'pthread_sigmask', which is safer in
675 multithreaded applications.
676 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
677 which has already arranged for that.
678 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
679 This is the main part of the bug fix.

700 Use Qstringp for default-directory, buffer-file-name,
701 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
702 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
704 * data.c (store_symval_forwarding): Adjust to call the predicate.
706 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
708 * w32.c (get_name_and_id, acl_set_file):

747 trailing dash is properly added.
749 2013-01-05 Eli Zaretskii <eliz@gnu.org>
751 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
752 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
753 digits for buffer positions, before misalignment starts.
754 Display "0" for integer "object" field.
755 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
756 Display the newline glyph more unambiguously.
758 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
760 * nsterm.m (ns_draw_underwave):
761 * w32term.c (w32_draw_underwave):
762 * xterm.c (x_draw_underwave): Make underwave look more triangular
763 and also degrade gracefully for small fonts. (Bug#13000)
765 * nsterm.m (ns_draw_text_decoration):
766 * w32term.c (x_draw_glyph_string):
767 * xterm.c (x_draw_glyph_string): Don't use previous underline
768 thickness and position if previous underline type is underwave.
770 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
772 * fileio.c (Ffile_acl): Undocument return format.
774 2013-01-02 Glenn Morris <rgm@gnu.org>
776 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
778 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
781 * dired.c (file_name_completion):

788 * term.c (tty_ins_del_lines):
789 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
790 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
792 2012-12-31 Eli Zaretskii <eliz@gnu.org>
794 * w32.c (unsetenv): Set up the string passed to _putenv
796 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
797 for the bug this caused.

814 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
815 Check toolbar_is_packed.
816 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
817 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
818 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
820 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
821 (xg_update_menubar): Update title only if
822 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
823 (xg_update_submenu): Skip tearoff only if
824 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
825 (xg_initialize): Initialize xg_detached_menus only if
826 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
828 * xterm.h (struct x_output): Surround handlebox_widget with
829 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
830 toolbar_in_hbox is bool.
832 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
834 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
835 (LIBS_GNUSTEP): Define.
836 (LIBES): Add $(LIBS_GNUSTEP).

839 2012-12-30 Eli Zaretskii <eliz@gnu.org>
841 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
842 continuation glyph on a TTY with an indication of an empty line.
845 2012-12-29 Eli Zaretskii <eliz@gnu.org>
847 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if

850 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
852 * w32proc.c (reader_thread): Avoid passing NULL handles to
853 SetEvent and WaitForSingleObject.
855 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>

861 2012-12-27 Glenn Morris <rgm@gnu.org>
863 * cygw32.c (Fcygwin_convert_file_name_to_windows)

866 2012-12-27 Eli Zaretskii <eliz@gnu.org>
868 * fileio.c (file_name_as_directory, directory_file_name):
869 Accept an additional argument MULTIBYTE to indicate whether the input C
870 came from a multibyte or a unibyte Lisp string; all callers
871 adjusted. Don't assume the input string is always multibyte.
873 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
874 don't ENCODE_FILE them, and return a unibyte string if the input
876 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
877 don't assume the input strings will always be multibyte. If the
878 input strings are multibyte, decode strings obtained from C
881 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
883 * lisp.h (toplevel): Add two notices to the comment about
884 defining a new Lisp data type.
885 * print.c (print_object): If Lisp_Save_Value object's pointer
886 is the address of a memory area containing Lisp_Objects, try
888 * alloc.c (valid_lisp_object_p): Adjust comment.
890 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
892 * keyboard.c (record_asynch_buffer_change): Initialize an event
893 only if it's really needed.
894 * frame.h (enum output_method): Remove output_mac member since
895 it's a leftover from the deleted code.
896 * frame.c (Fframep): Adjust user here ...
897 * terminal.c (Fterminal_live_p): ... and here.
898 * coding.c (Qmac): Now here because it's only used to denote
899 end-of-line encoding type.
900 (syms_of_coding): DEFSYM it.
901 * frame.h (Qmac): Remove duplicated declaration.
903 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
905 * window.c (select_window_1): Now static, since it's used only here.
907 2012-12-25 Eli Zaretskii <eliz@gnu.org>
909 * window.c (window_body_cols): Subtract display margins from the
910 window body width on TTYs as well. See
911 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
912 for the original report.
914 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
916 * xdisp.c (redisplay_window): Remove inner local variable
917 because the outer shadowed one has the same meaning.
918 * xterm.h (struct x_output): Remove toolbar_detached member since it's
920 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
921 (xg_create_tool_bar): Adjust users.
923 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
925 * buffer.h (BUF_COMPACT): New macro to follow the common style.
926 * buffer.c (Fget_buffer_create): Use it to set compact field of
927 struct buffer_text to avoid accessing an uninitialized value
928 when compact_buffer is called for the first time.
929 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
930 (Fset_buffer_modified_p): Use buffer_window_count to check
931 whether the buffer is displayed in some window.
932 * xdisp.c (message_dolog): Likewise.
934 2012-12-23 Eli Zaretskii <eliz@gnu.org>
936 * w32.c (acl_set_file): If setting the file security descriptor
937 fails, and the new DACL is identical to the existing one, silently
938 return success. This fixes problems for users backing up their
939 own files without having the necessary privileges for setting
940 security descriptors.
942 * w32proc.c (reader_thread): Do not index fd_info[] with negative
944 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
945 after WaitForSingleObject returns normally. This expedites reader
946 thread shutdown when delete_child triggers it.
947 (reap_subprocess): More accurate commentary for why we call
948 delete_child only when cp->fd is negative.
950 * w32.c (sys_close): Do not call delete_child on a subprocess
951 whose handle is not yet closed. Instead, set its file descriptor
952 to a negative value, so that reap_subprocess will call
953 delete_child on that subprocess when its SIGCHLD arrives.
954 This avoids closing handles used for communications between sys_select
955 and reader_thread, which doesn't give sys_select a chance to
956 notice that the process exited and invoke the SIGCHLD handler for
959 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>

977 * fileio.c (Finsert_file_contents): Doc fix.
979 * w32proc.c (new_child, delete_child, find_child_pid): For a
980 subprocess, consider its slot being in use as long as its process
981 handle (procinfo.hProcess) is not NULL. This avoids reusing the
982 slot when a new process is started immediately after killing
983 another one, without waiting enough time for the first process to
984 be reaped and resources allocated for it be orderly freed.
986 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
988 2012-12-21 Chong Yidong <cyd@gnu.org>

999 Remove now unused argument FNAME; all callers changed.
1000 (get_file_owner_and_group): Remove now unused argument FNAME; all
1003 2012-12-21 Chong Yidong <cyd@gnu.org>
1005 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1006 error for invalid chars, don't check for a nil return value.

1037 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1038 Rename 4th argument since it may be buffer or string. Adjust comment.
1039 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1041 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1043 * coding.c (Fdetect_coding_region): Do not check start and end with
1044 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1045 (code_convert_region): Likewise.
1047 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1049 * w32.c (acl_get_file, acl_set_file): Run the file name through

1065 (display_mode_lines): Complete last fix.
1066 * window.c (select_window_1): New func, extracted from select_window.
1067 (select_window): Use it.

1094 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1096 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1097 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1098 for some of that bug's symptoms can now cause Emacs to abort.
1099 Remove the workaround.
1100 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1101 The bug that caused SIGCHLD to get lost has been fixed, and the
1102 workaround for it can now cause Emacs to abort.
1104 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1106 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1107 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in

1114 and copy ACL entries of file in addition to SELinux context if set.
1115 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1117 * Makefile.in (LIBACL_LIBS): New macro.

1144 * lisp.h (internal_delete_file): Adjust prototype.
1146 * callproc.c (Fcall_process): Don't overwrite infile with result
1148 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1149 asynchronous subprocess, record the name of the input file name,
1151 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1152 delete the file, record it as pending deletion when the subprocess
1155 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1157 * editfns.c [HAVE_PWD_H]: Include grp.h.

1163 Fix permissions bugs with setgid directories etc. (Bug#13125)
1164 * dired.c (Ffile_attributes): Return t as the 9th attribute,

1168 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1175 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1177 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1178 try to get accurate owner and group information from NT file
1179 security APIs. This is to make most callers of 'stat' and
1180 'lstat', which don't need that information, much faster.
1182 * dired.c (Ffile_attributes) [WINDOWSNT]:
1183 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1184 owner and group information from 'lstat'.
1186 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1188 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1189 as that confuses set-auto-coding, so insist on the head-read

1194 (init_iterator): Hoist assignment out of if-expression.
1195 (markpos_of_region): Callers now test for sign, not for -1.

1214 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1215 files, fixing a regression from 24.2.
1216 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1218 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1220 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1221 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1222 Remove unnecessary S_ISLNK test, as (contra the comments) this
1223 function can't copy symlinks. Improve quality of error message
1224 when attempting to copy files that are neither regular files nor

1233 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1235 2012-12-12 Daniel Colascione <dancol@dancol.org>
1237 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1238 the dumped Emacs is not a sparse file, greatly improving Cygwin
1239 "make bootstrap" performance.
1241 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1243 * inotify.c (inotify_callback): Generate an Emacs event for every
1244 incoming inotify event.
1246 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1248 * xdisp.c (handle_face_prop): Fix logic of computing
1249 it->start_of_box_run_p.
1250 (append_space_for_newline): If the glyph row is R2L, reset the
1251 iterator's end_of_box_run_p flag before prepending the space glyph.
1252 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1253 iterator's start_of_box_run_p flag before prepending the stretch.

1255 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1256 left_box_line_p and right_box_line_p flags of the glyph for R2L
1257 glyph rows. (Bug#13011)

1307 (hinst): Remove unneeded extern declaration.
1308 (_start): Remove initialization of above variables; remove

1449 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1451 * w32.c (unsetenv): Return 0 if the input string is too long.
1453 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1455 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1456 * alloc.c (xputenv): New function.
1457 * dbusbind.c (Fdbus_init_bus):
1459 * xterm.c (x_term_init):
1460 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1461 * editfns.c (initial_tz): Move static var decl up.
1462 (tzvalbuf_in_environ): New static var.
1463 (init_editfns): Initialize these two static vars.
1464 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1465 Save old TZ value on stack, if it's small.
1466 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1467 instead, use xputenv+unsetenv to set and restore TZ.
1468 (environbuf): Remove static var. All uses removed.
1469 (Fset_time_zone_rule): Do not save TZ and environ;
1470 no longer needed here.
1471 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1472 Move to inside set_time_zone_rule; they don't need file scope any more.
1473 (set_time_zone_rule): Maintain the TZ=value string separately.
1474 (syms_of_editfns): Don't initialize initial_tz;
1475 init_editfns now does it.
1476 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1477 * lisp.h (xputenv): New decl.
1479 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1481 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1483 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1485 * w32.c (unsetenv, sys_putenv): New functions.
1487 2012-12-08 Chong Yidong <cyd@gnu.org>
1489 * editfns.c (Finsert_char): Make the error message more
1490 informative (Bug#12992).
1492 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1494 Simplify get_lim_data.
1495 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1496 Remove USG and vlimit methods; no longer used these days.
1497 Add #error catchall just in case.
1499 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1500 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1501 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1502 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1503 (deleted_pid_list, Fdelete_process, create_process)
1504 (record_child_status_change, handle_child_signal, deliver_child_signal)
1505 (init_process_emacs, syms_of_process):
1506 Assume SIGCHLD is defined.
1507 (parse_signal): Remove. All uses removed.
1508 (abbr_to_signal): New static function.
1509 (Fsignal_process): Use it to convert signal names to ints.
1510 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1511 kill (getpgrp (), ...).
1512 (emacs_sigaction_init): Assume SIGCHLD is defined.
1513 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1514 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1515 * syssignal.h (EMACS_KILLPG): Remove.
1516 All uses replaced by 'kill' with a negative pid.
1517 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1518 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1520 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1522 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1523 This will cause a production Emacs to dump core instead of
1526 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1528 * frame.c (make_frame): Do not set window's buffer to t.
1529 * window.c (Fsplit_window_internal): Likewise. Previously it was
1530 used to indicate that the window is being set up. Now we use
1531 set_window_buffer for all new windows, so the condition in ...
1532 (Fset_window_buffer): ... is always true and can be removed.
1534 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1536 Convenient macro to check whether the buffer is hidden.
1537 * buffer.h (BUFFER_HIDDEN_P): New macro.
1538 * frame.c (make_frame): Use it. Adjust comment.
1539 * buffer.c (candidate_buffer): New function.
1540 (Fother_buffer, other_buffer_safely): Use it.
1542 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1544 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1545 if the child process is still running. Instead, exit the wait
1546 loop and return zero. (Bug#13086)
1548 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1550 * frame.h (x_char_width, x_char_height): Remove prototypes.
1551 * w32term.h (x_char_width, x_char_height): Likewise.
1552 * xfns.c (x_char_width, x_char_height): Remove.
1553 * w32fns.c (x_char_width, x_char_height): Likewise.
1554 * nsfns.c (x_char_width, x_char_height): Likewise.

1561 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1563 Fix a recently-introduced delete-process race condition.
1564 * callproc.c, process.h (record_kill_process):
1565 New function, containing part of the old call_process_kill.
1566 (call_process_kill): Use it.
1567 This does not change call_process_kill's behavior.
1568 * process.c (Fdelete_process): Use record_kill_process to fix a
1569 race condition that could cause Emacs to lose track of a child.
1571 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1573 Avoid code duplication between prev_frame and next_frame.
1574 * frame.c (candidate_frame): New function. Add comment.
1575 (prev_frame, next_frame): Use it. Adjust comment.
1577 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1579 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1580 fails, signal an error instead of continuing with an empty
1582 Encode expanded temp file pattern before passing it to mkstemp or
1585 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1586 Encode the file name before passing it to dostounix_filename, in
1587 case it will downcase it (under w32-downcase-file-names).
1590 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1592 Minor call-process cleanups.
1593 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1594 at the same time as other platforms, to simplify analysis.
1595 No need for fd0_volatile since we have synch_process_fd.
1596 Avoid needless emacs_close; arg is always negative.
1598 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1600 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1603 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1605 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1606 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1607 and mouse_face_hidden members to a bitfields.
1608 * frame.h (struct frame): Remove set-but-not-used space_width member.
1609 (FRAME_SPACE_WIDTH): Remove.
1610 * nsterm.m, w32term.c, xterm.c: Adjust users.
1611 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1612 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1613 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1614 members to a bitfields.
1616 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1618 Don't let call-process be a zombie factory (Bug#12980).
1619 Fixing this bug required some cleanup of the signal-handling code.
1620 As a side effect, this change also fixes a longstanding rare race
1621 condition whereby Emacs could mistakenly kill unrelated processes,
1622 and it fixes a bug where a second C-g does not kill a recalcitrant
1623 synchronous process in GNU/Linux and similar platforms.
1624 The patch should also fix the last vestiges of Bug#9488,
1625 a bug which has mostly been fixed on the trunk by other changes.
1626 * callproc.c, process.h (synch_process_alive, synch_process_death)
1627 (synch_process_termsig, sync_process_retcode):
1628 Remove. All uses removed, to simplify analysis and so that
1629 less consing is done inside critical sections.
1630 * callproc.c (call_process_exited): Remove. All uses replaced
1631 with !synch_process_pid.
1632 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1633 These take the role of what used to be in unwind-protect arg.
1635 (block_child_signal, unblock_child_signal):
1636 New functions, to avoid races that could kill innocent-victim processes.
1637 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1638 (call_process_kill): Record killed processes as deleted, so that
1639 zombies do not clutter up the system. Do this inside a critical
1640 section, to avoid a race that would allow the clutter.
1641 (call_process_cleanup): Fix code so that the second C-g works again
1642 on common platforms such as GNU/Linux.
1643 (Fcall_process): Create the child process in a critical section,
1644 to fix a race condition. If creating an asynchronous process,
1645 record it as deleted so that zombies do not clutter up the system.
1646 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1647 light of these changes. Omit unnecessary call to emacs_close
1648 before failure, as the unwind-protect code does that.
1649 * callproc.c (call_process_cleanup):
1650 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1651 * process.c (record_deleted_pid): New function, containing
1652 code refactored out of Fdelete_process.
1653 (Fdelete_process): Use it.
1654 (process_status_retrieved): Remove. All callers changed to use
1655 child_status_change.
1656 (record_child_status_change): Remove, folding its contents into ...
1657 (handle_child_signal): ... this signal handler. Now, this
1658 function is purely a handler for SIGCHLD, and is not called after
1659 a synchronous waitpid returns; the synchronous code is moved to
1660 wait_for_termination. There is no need to worry about reaping
1661 more than one child now.
1662 * sysdep.c (get_child_status, child_status_changed): New functions.
1663 (wait_for_termination): Now takes int * status and bool
1664 interruptible arguments, too. Do not record child status change;
1665 that's now the caller's responsibility. All callers changed.
1666 Reimplement in terms of get_child_status.
1667 (wait_for_termination_1, interruptible_wait_for_termination):
1668 Remove. All callers changed to use wait_for_termination.
1669 * syswait.h: Include <stdbool.h>, for bool.
1670 (record_child_status_change, interruptible_wait_for_termination):
1672 (record_deleted_pid, child_status_changed): New decls.
1673 (wait_for_termination): Adjust to API changes noted above.
1675 * bytecode.c, lisp.h (Qbytecode): Remove.
1676 No longer needed after 2012-11-20 interactive-p changes.
1678 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1680 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1681 the scroll margin, move point outside the margin. (Bug#13055)
1683 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1685 * gtkutil.c (my_log_handler): New function.
1686 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1688 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1690 * lisp.h (modify_region): Rename to...
1691 (modify_region_1): ...new prototype.
1692 * textprop.c (modify_region): Now static. Adjust users.
1693 * insdel.c (modify_region): Rename to...
1694 (modify_region_1): ...new function to work with current buffer.
1695 Adjust comment and users. Use true and false for booleans.
1697 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1699 * alloc.c (free_save_value): New function.
1700 (safe_alloca_unwind): Use it.
1701 * lisp.h (free_save_value): New prototype.
1702 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1704 (save_excursion_restore): Adjust to match saved data structure.
1705 Use free_save_value to offload some work from GC. Drop obsolete
1708 2012-12-03 Chong Yidong <cyd@gnu.org>
1710 * fileio.c (Vauto_save_list_file_name): Doc fix.
1712 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1714 * w32fns.c: Remove prototype of atof.
1715 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1717 (file_dialog_callback): Make it UINT_PTR.
1719 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1722 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1723 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1726 2012-12-03 Glenn Morris <rgm@gnu.org>
1728 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1730 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1732 Fix xpalloc confusion after memory is exhausted.
1733 * alloc.c (xpalloc): Comment fix.
1734 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1735 and signals an error, do not clear charset_table_size, as
1736 charset_table is still valid.
1737 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1739 Use execve to avoid need to munge environ (Bug#13054).
1740 * callproc.c (Fcall_process):
1741 * process.c (create_process):
1742 Don't save and restore environ; no longer needed.
1743 * callproc.c (child_setup):
1744 Use execve, not execvp, to preserve environ.
1746 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1748 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1750 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1752 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1753 display for sliced images (Bug#10500).
1755 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1757 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1759 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1760 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1762 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1764 * xdisp.c (window_outdated): Remove eassert since it hits
1765 some suspicious corner cases (see Bug#13007 and Bug#13012).
1766 (mode_line_update_needed): New function.
1767 (redisplay_internal, redisplay_window): Use it.
1768 (ensure_selected_frame): New function.
1769 (redisplay_internal, unwind_redisplay): Use it.
1770 (redisplay_internal): Move comment about buffer_shared...
1771 (buffer_shared_and_changed): ...near to its real use.
1773 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1775 * callproc.c (Fcall_process): Don't misreport vfork failure.
1777 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1779 * callproc.c (Fcall_process): Fix vfork portability problems.
1780 Do not assume that fd[0], count, filefd, and save_environ survive
1781 vfork. Fix bug whereby wrong errno value could be reported for
1782 pipe failure. Some minor cleanups, too, as follows. Move buf and
1783 bufsize to the context where they're needed. Change new_argv to
1784 be of type char **, as this is more convenient and avoids casts.
1785 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1786 Now local constants, not macros.
1788 2012-11-18 Kenichi Handa <handa@gnu.org>
1790 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1791 for the variable "f".
1793 2012-11-13 Kenichi Handa <handa@gnu.org>
1795 * font.c (font_unparse_xlfd): Exclude special characters from the
1796 generating XLFD name.
1798 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1800 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1802 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1804 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1808 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1809 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.

1811 * lread.c (readbyte_from_file): Assume EINTR is defined.
1812 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1813 Assume EIO and EAGAIN are defined.
1814 * unexcoff.c (write_segment): Assume EFAULT is defined.
1816 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1818 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1821 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1822 highlighting on the frame was cleared. Prevents assertion
1823 violations when repeatedly clicking on the "Top" link of the
1824 "bread-crumbs" in Info buffers.
1826 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1828 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1830 2012-11-24 Ken Brown <kbrown@cornell.edu>
1832 * keyboard.c (HAVE_MOUSE):
1833 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1834 were always defined.
1836 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1838 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1839 between bpos_covered and bpos_max. This fixes cursor display when
1840 several display strings follow each other.
1842 * .gdbinit (pgx): If the glyph's object is a string, display the
1843 pointer to string data, rather than the value of the string object
1844 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1846 * indent.c (Fvertical_motion): If the starting position is covered
1847 by a display string, return to one position before that, to avoid
1848 overshooting it inside move_it_to. (Bug#12930)
1850 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1852 * frame.h (struct frame): Remove display_preempted member

1855 * w32menu.c (pending_menu_activation): Remove since not
1857 (set_frame_menubar): Adjust user.
1858 * w32term.h (struct x_output): Drop outdated #if 0 code.
1859 (struct w32_output): Use bitfields for explicit_parent,
1860 asked_for_visible and menubar_active members.
1861 Drop unused pending_menu_activation member.
1862 * xterm.h (struct x_output): Drop outdated #if 0 code.
1863 Use bitfields for explicit_parent, asked_for_visible,
1864 has_been_visible and net_wm_state_hidden_seen members.
1866 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1868 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1869 of a literal "/". (Bug#12955)
1870 (gl-stamp): Invoke fc.exe directly, not through cmd.
1872 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1874 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1875 * dired.c: Assume HAVE_DIRENT_H.
1876 (NAMLEN): Remove, replacing with ...
1877 (dirent_namelen): New function. All uses changed. Use the GNU macro
1878 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1879 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1880 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1881 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1883 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1884 * ndir.h: Rename to ../nt/inc/dirent.h.
1885 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1886 Do not include <dirent.h>; no longer needed.
1887 * w32.c: Include <dirent.h> rather than "ndir.h".
1889 2012-11-23 Chong Yidong <cyd@gnu.org>
1891 * xftfont.c (xftfont_open): Remove duplicate assignment.
1893 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1895 * alloc.c (Fgarbage_collect): Unblock input after clearing
1896 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1897 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1898 * msdos.c (IT_frame_up_to_date): Use it here...
1899 * w32term.c (w32_frame_up_to_date): ...here...
1900 * xterm.c (XTframe_up_to_date): ...and here...
1901 * nsterm.m (ns_frame_up_to_date): ...but not here.
1902 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1904 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1905 Do not check whether GC is in progress.
1907 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1909 * xdisp.c (window_buffer_changed): New function.
1910 (update_menu_bar, update_tool_bar): Use it to
1911 simplify large 'if' statements.

1913 'tail' and 'frame' local variables.
1915 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1917 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1918 with Windows system header.
1920 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1922 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1923 * alloc.c: Assume unistd.h exists.
1924 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1925 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1926 (getwd) [USG]: Remove; no longer needed.
1927 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1928 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1929 * w32.h (getcwd): Remove decl.
1931 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1933 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1934 Make it set selected_window as well.
1935 (update_tool_bar): Use it.
1937 2012-11-21 Ken Brown <kbrown@cornell.edu>
1939 * emacs.c (main): Set the G_SLICE environment variable for all
1940 Cygwin builds, not just GTK builds. See
1941 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1943 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1945 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1946 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1947 Define for the MSVC compiler.
1949 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1951 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1952 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1953 dostounix_filename. Prevents crashes down the road, because
1954 dostounix_filename assumes it gets a unibyte string.
1955 Reported by Michel de Ruiter <michel@sentient.nl>, see
1956 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1958 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1962 * lread.c (init_obarray): Set `function' fields to Qnil.
1963 * eval.c (Fcommandp): Ignore Qunbound.
1964 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1965 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1966 Test NILP rather than Qunbound.
1967 (Ffmakunbound): Set to Qnil.
1968 (Fsymbol_function): Never signal an error.
1969 (Finteractive_form): Ignore Qunbound.
1971 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1973 * eval.c (interactive_p): Remove no-longer-used decl.
1975 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1977 * xdisp.c (buffer_shared): Adjust comment.
1978 (buffer_shared_and_changed): New function.
1979 (prepare_menu_bars, redisplay_internal): Use it to
1980 decide whether all windows or frames should be updated.
1981 (window_outdated): New function.
1982 (text_outside_line_unchanged_p, redisplay_window): Use it.
1983 (redisplay_internal): Likewise. Fix indentation.
1985 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1987 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1988 (syms_of_eval): Remove corresponding defsubr.
1989 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1991 2012-11-19 Daniel Colascione <dancol@dancol.org>
1993 * w32fns.c (Fx_file_dialog):
1994 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1995 cygwin_convert_file_name*.
1997 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1998 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2000 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2002 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2004 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2006 * w32select.c: Include w32common.h before w32term.h, so that
2007 windows.h gets included before w32term.h uses some of its
2008 features, see below.
2010 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2012 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2014 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2016 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2018 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2019 (ns_select): Return at once if events are held (Bug#12834).
2021 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2023 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2024 Needed following 2012-10-20 change. (Bug#12902)
2026 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2028 * w32proc.c (waitpid): Remove unused label get_result.
2030 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2032 * makefile.w32-in (SYSWAIT_H): New macro.
2033 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2034 ($(BLD)/sysdep.$(O)): Update dependencies.
2036 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2038 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2039 * callproc.c (relocate_fd): Assume F_DUPFD.
2040 * emacs.c, term.c (O_RDWR): Remove.
2041 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2042 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2043 * nsterm.m: Assume <fcntl.h> exists.
2044 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2045 (create_pty, Fmake_network_process, server_accept_connection)
2046 (wait_reading_process_output, init_process_emacs):
2048 (wait_reading_process_output): Put in a special case for WINDOWSNT
2049 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2050 It's not clear this is needed, but it's a more-conservative change.
2051 (create_process): Assume FD_CLOEXEC.
2052 (create_process, create_pty): Assume O_NOCTTY.
2053 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2054 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2055 Omit if not DOS_NT, since F_GETFL is not defined there.
2056 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2057 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2059 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2060 lack it, since gnulib guarantees this.
2061 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2063 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2065 * w32.c (faccessat): Pretend that directories have the execute bit
2066 set. Emacs expects that, e.g., in files.el:cd-absolute.
2068 * w32proc.c (create_child): Don't clip the PID of the child
2069 process to fit into an Emacs integer, as this is no longer a
2071 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2072 reaping only the process specified by PID argument, if that is
2073 positive. Use PID instead of dead_child to know which process to
2074 reap. Wait for the child to die only if WNOHANG is not in
2076 (sys_select): Don't set dead_child.
2078 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2079 as it is no longer needed.
2081 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2083 (record_child_status_change): Remove the setting of
2084 record_at_most_one_child for the !WNOHANG case.
2086 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2088 Fix problems in ns port found by static checking.
2089 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2090 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2091 not to process group.
2092 (ns_select): Use emacs_write, not write, as that's more robust
2093 in the presence of signals.
2094 (fd_handler:): Check for read errors.
2096 2012-11-16 Glenn Morris <rgm@gnu.org>
2098 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2100 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2102 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2104 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2106 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2107 use the same value of thread handle.
2108 (start_timer_thread): If the timer thread exited (due to error),
2109 clean up by closing the two handles it used. Duplicate the caller
2110 thread's handle here, so it gets duplicated only once, when
2111 launching the timer thread. Set priority of the timer thread, not
2113 (getitimer): Don't duplicate the caller thread's handle here.
2116 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2118 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2121 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2123 Remove no-longer-used pty_max_bytes variable.
2124 * process.c (pty_max_bytes): Remove; unused.
2125 (send_process): Do not set it.
2127 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2129 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2130 Update dependencies.
2132 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2134 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2135 This follows up on the 2012-09-29 patch that removed indirection
2136 for the 'function' field. Reported by Sergey Vinokurov in
2137 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2139 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2141 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2142 different name, as the MS runtime does not have such a function,
2143 and probably never will.) All callers changed. Ignore DIRFD
2144 value if PATH is an absolute file name, to match Posix spec
2145 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2148 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2150 * xdisp.c (echo_area_display, redisplay_internal):
2151 Omit redundant check whether frame_garbaged is set.
2153 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2155 Use faccessat, not access, when checking file permissions (Bug#12632).
2156 This fixes a bug that has been present in Emacs since its creation.
2157 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2158 which must set some sort of record. (Torek's bug report was against
2159 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2160 same common flaw.) See Torek's Usenet posting
2161 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2162 Posted: Fri Apr 8 14:18:56 1983.
2163 * Makefile.in (LIB_EACCESS): New macro.
2165 * callproc.c (init_callproc):
2166 * charset.c (init_charset):
2167 * fileio.c (check_existing, check_executable, check_writable)
2169 * lread.c (openp, load_path_check):
2170 * process.c (allocate_pty):
2172 Use effective UID when checking permissions, not real UID.
2173 * callproc.c (init_callproc):
2174 * charset.c (init_charset):
2175 * lread.c (load_path_check, init_lread):
2176 Test whether directories are accessible, not merely whether they exist.
2177 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2178 * fileio.c (check_existing, check_executable, check_writable)
2180 Use symbolic names instead of integers for the flags, as they're
2182 (check_writable): New arg AMODE. All uses changed.
2183 Set errno on failure.
2184 (Ffile_readable_p): Use faccessat, not stat + open + close.
2185 (Ffile_writable_p): No need to call check_existing + check_writable.
2186 Just call check_writable and then look at errno. This saves a syscall.
2187 dir should never be nil; replace an unnecessary runtime check
2188 with an eassert. When checking the parent directory of a nonexistent
2189 file, check that the directory is searchable as well as writable, as
2190 we can't create files in unsearchable directories.
2191 (file_directory_p): New function, which uses 'stat' on most platforms
2192 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2193 (Ffile_directory_p, Fset_file_times): Use it.
2194 (file_accessible_directory_p): New function, which uses a single
2195 syscall for efficiency.
2196 (Ffile_accessible_directory_p): Use it.
2197 * xrdb.c (file_p): Use file_directory_p.
2198 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2199 * lread.c (openp): When opening a file, use fstat rather than
2200 stat, as that avoids a permissions race. When not opening a file,
2201 use file_directory_p rather than stat.
2202 (dir_warning): First arg is now a usage string, not a format.
2203 Use errno. All uses changed.
2204 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2205 that merely introduced a race.
2206 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2207 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2208 and similarly for the other O_* flags.
2209 * w32.c (sys_faccessat): Rename from sys_access and switch to
2210 faccessat's API. All uses changed.
2211 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2212 (magic_db): Rename from magic_file_p.
2213 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2214 char *, so that we don't have to test for file existence
2215 separately from opening the file for reading. This removes a race
2216 fixes a permission-checking problem, and simplifies the code.
2218 (file_p): Remove; no longer needed.
2220 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2222 Omit glyphs initialization at startup.
2223 * dispnew.c (glyphs_initialized_initially_p): Remove.
2224 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2225 (Fredraw_frame): Move actual code from here...
2226 (redraw_frame): ...to here. Add eassert. Adjust comment.
2227 (Fredraw_display): Use redraw_frame.
2228 * xdisp.c (clear_garbaged_frames): Likewise.
2230 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2232 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2233 passed to pint2str and pint2hrstr to be at most the size of the
2234 frame's decode_mode_spec_buffer. This avoids crashes with very
2235 large values of FIELD_WIDTH argument to decode_mode_spec.
2238 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2240 Fix a race with verify-visited-file-modtime (Bug#12863).
2241 Since at least 1991 Emacs has ignored an mtime difference of no
2242 more than one second, but my guess is that this was to work around
2243 file system bugs that were fixed long ago. Since the race is
2244 causing problems now, let's remove that code.
2245 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2246 whose time stamp is off by no more than a second. Insist that the
2247 file time stamps match exactly.
2249 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2251 * frame.h (struct frame): Convert external_tool_bar member to
2252 1-bit unsigned bitfield.
2253 * termhooks.h (struct terminal): Remove mouse_moved member since
2254 all users are long dead. Adjust comment on mouse_position_hook.
2256 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2258 Simplify by using FOR_EACH_FRAME here and there.
2259 * frame.c (next_frame, prev_frame, other_visible_frames)
2260 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2261 * w32term.c (x_window_to_scroll_bar): Likewise.
2262 * window.c (window_list): Likewise.
2263 * xdisp.c (x_consider_frame_title): Likewise.
2264 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2265 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2266 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2267 * xmenu.c (menubar_id_to_frame): Likewise.
2268 * xselect.c (frame_for_x_selection): Likewise.
2269 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2270 (x_window_to_menu_bar): Likewise.
2271 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2273 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2275 * data.c (Qdefalias_fset_function): Now static.
2277 Another tweak to vectorlike_header change.
2278 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2279 Remove, and replace all uses with ...
2280 (next_in_free_list, set_next_in_free_list):
2281 New functions, which respect C's aliasing rules better.
2283 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2285 * window.c (list4i): Rename from 'quad'. All uses changed.
2286 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2288 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2290 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2291 warning about mixing declarations and code in ISO C90.
2293 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2295 * window.c (Fsplit_window_internal): Set combination limit of
2296 new parent window to t iff Vwindow_combination_limit is t;
2297 fixing a regression introduced with the change from 2012-09-22.
2298 (Fset_window_combination_limit): Fix doc-string.
2300 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2302 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2303 amount when the scroll margins are too large. When scrolling
2304 backwards in the buffer, give up if cannot reach point or the
2305 scroll margin within a reasonable number of screen lines.
2306 Fixes point position in window under scroll-up/down-aggressively when
2307 point is positioned many lines beyond the window top/bottom.
2310 * ralloc.c (relinquish): If real_morecore fails to return memory
2311 to the system, don't crash; instead, leave the last heap
2312 unchanged and return. (Bug#12774)
2314 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2316 * lisp.h (AUTOLOADP): New macro.
2317 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2318 * data.c (Ffset): Remove special ad-advice-info handling.
2319 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2321 (Finteractive_form): Simplify.
2322 (Fquo): Don't insist on having at least 2 arguments.
2323 (Qdefalias_fset_function): New var.
2325 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2327 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2329 * nsfont.m (Qcondensed, Qexpanded): New variables.
2330 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2331 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2333 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2335 Fix recently introduced crash on MS-Windows (Bug#12839).
2336 * w32term.h (struct scroll_bar): Use convenient header.
2337 (SCROLL_BAR_VEC_SIZE): Remove.
2338 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2340 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2342 Tweak last vectorlike_header change.
2343 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2344 vectorlike object on the free list. This is introduced to avoid

2351 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2353 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

2379 special hash function containing a comparison that always yields 1.
2381 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2383 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2384 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2385 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2388 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2390 * image.c (xpm_make_color_table_h): Fix compiler error because
2391 make_hash_table changed.
2393 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2395 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2397 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2399 Use ad-hoc comparison function for the profiler's hash-tables.
2400 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2401 (make_log): Use them.

2412 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2413 (hash_lookup, hash_remove_from_table): Move assertion checking of
2414 hashfn result here. Check hash-equality before calling cmpfn.

2427 value of w32-scroll-lock-modifier is neither nil nor one of the
2428 known key modifiers. (Bug#12806)
2430 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2432 Shrink struct vectorlike_header to the only size field.
2433 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2435 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2436 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2437 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2438 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2439 information from the vector header. Adjust comment.

2460 (allocate_vectorlike): Likewise.
2461 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2462 Add easserts. Adjust XSETPVECTYPESIZE usage.
2463 (allocate_buffer): Use BUFFER_PVEC_INIT.
2464 (live_vector_p): Adjust to match large vector.
2465 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2466 * buffer.h (struct buffer): Add next member.
2467 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):

2477 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2479 * keyboard.c (event_to_kboard): Do not dereference
2480 frame_or_window field of SELECTION_REQUEST_EVENT
2481 and SELECTION_CLEAR_EVENT events (Bug#12814).
2482 * xterm.h (struct selection_input_event): Adjust comment.
2484 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2486 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2487 such as Scroll Lock, if the respective keys are treated as
2488 function keys, not as modifiers. This avoids destroying non-ASCII
2489 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2491 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2493 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2495 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2497 Restore some duplicate definitions (Bug#12814).
2498 This undoes part of the 2012-11-03 changes. Some people build
2499 with plain -g rather than with -g3, and they need the duplicate
2500 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2501 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2502 Define as macros, as well as as enums or as constants.
2504 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2506 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2507 to keypad keys (Bug#12816).
2509 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2511 Minor adjustments of recently-changed frame functions.
2512 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2513 known to be a frame (we're in the FRAMEP branch).
2514 * lisp.h (Qframep): Remove decl. frame.h declares this.
2515 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2516 since they're meant for Lisp fixnum values.
2518 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2520 * window.c (Fwindow_combination_limit): Revert to the only
2521 required argument and adjust docstring as suggested in
2522 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2523 by Martin Rudalics <rudalics@gmx.at>.
2525 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2527 Widely used frame validity and checking functions.
2528 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2529 * frame.c (decode_live_frame, decode_any_frame): New functions.
2530 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2531 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2532 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2540 * lisp.h (frame_buffer_predicate): Remove prototype.
2541 * buffer.c (Fother_buffer): Use decode_any_frame.
2542 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2543 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2544 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2545 (Fclose_font, Ffont_info): Use decode_live_frame.
2546 * fontset.c (check_fontset_name): Likewise.
2547 * terminal.c (Fframe_terminal): Likewise.
2548 * w32fns.c (check_x_frame): Likewise.
2549 * window.c (Fminibuffer_window, Fwindow_at)
2550 (Fcurrent_window_configuration): Likewise.
2551 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2552 Likewise. Allow zero number of arguments. Adjust docstring.
2553 * dispnew.c (Fredraw_frame): Likewise.
2554 * xfaces.c (frame_or_selected_frame): Remove.
2555 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2556 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2557 (Fframe_face_alist): Use decode_live_frame.
2558 * xfns.c (check_x_frame): Likewise.
2560 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2562 * window.c (quad): New function.
2563 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2564 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2565 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2566 (Fwindow_line_height): Use it.
2567 (Fwindow_fringes): Use list3.
2568 (Fwindow_scroll_bars): Use list4.
2569 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2570 (Fwindow_combination_limit): Allow zero number of arguments.
2572 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2574 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2576 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2577 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2578 file descriptor 2 for standard error. (Bug#12805)
2580 2012-11-05 Chong Yidong <cyd@gnu.org>
2582 * process.c (wait_reading_process_output): Revert previous change.
2584 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2586 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2587 This removes code that has been obsolete since around 1990.
2588 * callproc.c (Fcall_process):
2590 * process.c (create_process):
2591 * term.c (dissociate_if_controlling_tty):
2592 Assume setsid exists.
2593 * callproc.c (child_setup): Assume setpgid exists and behaves as
2594 per POSIX.1-1988 or later.
2595 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2596 * emacs.c (shut_down_emacs):
2597 * sysdep.c (sys_suspend, init_foreground_group):
2598 Assume getpgrp behaves as per POSIX.1-1998 or later.
2599 * msdos.c (setpgrp): Remove.
2600 (tcgetpgrp, setpgid, setsid): New functions.
2601 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2602 * term.c (no_controlling_tty): Remove; unused.
2603 * w32proc.c (setpgrp): Remove.
2604 (setsid, tcgetpgrp): New functions.
2606 Simplify by assuming __fpending.
2607 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2608 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2609 Do not assume that __fpending's result fits in int.
2611 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2613 Remove EMACS_OUTQSIZE+sleep hack.
2614 * dispnew.c (update_frame_1): Remove hack for terminals slower
2615 than 2400 bps, which throttled Emacs by having it sleep.
2616 This code hasn't worked since at least 2007, when the multi-tty stuff
2617 was added, and anyway those old terminals are long dead.
2618 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2619 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2621 Fix data-loss with --version (Bug#9574).
2622 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2623 as we can't assume that emacs_strerror is initialized, and strerror
2624 is good enough here.
2625 (main): Invoke atexit earlier, to catch earlier instances of
2626 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2628 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2630 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2631 (keyDown): Remap keypad keys to X11 virtual key codes.
2633 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2635 Fix data-loss with --batch (Bug#9574).
2636 * emacs.c: Include <close-stream.h>.
2637 (close_output_streams): New function.
2638 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2639 and handles errors appropriately.
2640 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2643 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2644 The symptom is a diagnostic "GLib-WARNING **: In call to
2645 g_spawn_sync(), exit status of a child process was requested but
2646 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2647 waitpid(), so exit status can't be returned." The diagnostic
2648 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2649 The real bug is a race condition between Emacs and glib: Emacs
2650 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2651 so that glib can't find it. Work around the bug by invoking
2652 waitpid only on subprocesses that Emacs itself creates.
2653 * process.c (create_process, record_child_status_change):
2654 Don't use special value -1 in pid field, as the caller now must
2655 know the pid rather than having the callee infer it.
2656 The inference was sometimes incorrect anyway, due to another race.
2657 (create_process): Set new 'alive' member if child is created.
2658 (process_status_retrieved): New function.
2659 (record_child_status_change): Use it.
2660 Accept negative 1st argument, which means to wait for the
2661 processes that Emacs already knows about. Move special-case code
2662 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2663 processes that have already been waited for, by testing and
2664 clearing new 'alive' member.
2665 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2666 now does this internally.
2667 (handle_child_signal): Let record_child_status_change do all
2668 the work, since we do not want to reap all exited child processes,
2669 only the child processes that Emacs itself created.
2670 * process.h (Lisp_Process): New boolean member 'alive'.
2672 Omit duplicate definitions no longer needed with gcc -g3.
2673 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2674 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2675 Define only as macros. There's no longer any need to also define
2676 these symbols as enums or as constants, since we now assume
2677 gcc -g3 when debugging.
2679 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2681 * lisp.mk: Adjust comments to the fact that term/internal is now
2682 loaded from loadup.el.
2684 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2685 (msdos_fatal_signal): New function.
2686 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2689 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2690 for GCC versions before 4.
2691 (emacs_raise): Define to call msdos_fatal_signal.
2693 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2694 iterator when starting in the middle of a display or overlay
2697 2012-11-03 Chong Yidong <cyd@gnu.org>
2699 * process.c (wait_reading_process_output): Clean up the last
2702 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2704 * process.c (wait_reading_process_output): Avoid a race condition
2705 with SIGIO delivery (Bug#11536).
2707 2012-11-03 Chong Yidong <cyd@gnu.org>
2709 * buffer.c (cursor_type): Untabify docstring.
2711 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2713 * frame.h (struct frame): Drop can_have_scroll_bars member
2714 which is meaningless for a long time. Adjust comments.
2715 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2716 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2718 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2720 * window.c (decode_next_window_args): Update window arg after
2721 calling decode_live_window and so fix crash reported at
2722 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2723 by Juanma Barranquero <lekktu@gmail.com>.
2724 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2725 * font.c (Ffont_at): Likewise.
2727 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2729 * widget.c (resize_cb): New function.
2730 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2731 (EmacsFrameResize): Check if all is up to date before changing frame
2734 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2736 Implement backtrace output for fatal errors on MS-Windows.
2737 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2738 (BACKTRACE_LIMIT_MAX): New macro.
2739 (w32_backtrace): New function.
2740 (emacs_abort): Use w32_backtrace when the user chooses not to
2741 attach a debugger. Update the text of the abort dialog.
2743 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2745 Window-related stuff cleanup here and there.
2746 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2747 Use decode_any_window.
2748 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2749 * xdisp.c (Fformat_mode_line): Likewise.
2750 * font.c (Ffont_at): Use decode_live_window.
2751 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2752 * window.c (decode_next_window_args): Likewise.
2753 (decode_any_window): Remove static.
2754 * window.h (decode_any_window): Add prototype.
2755 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2756 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2759 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2761 Remove pad from struct input_event.
2762 * termhooks.h (struct input_event): Remove padding field.
2764 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2765 member is never cons for a long time. Adjust comment.
2766 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2767 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2768 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2769 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2771 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2773 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2775 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2777 Fix crash when using Emacs as commit editor for git (Bug#12697).
2778 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2779 and it is configured in conf_post.h.
2780 (Fcall_process): Don't invoke both setsid and setpgid; the former
2781 is enough, if it exists.
2782 * callproc.c (Fcall_process, child_setup):
2783 * process.c (create_process): Use setpgid.
2784 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2786 * dispnew.c (init_display): Initialize the foreground group
2787 if we are running a tty display.
2788 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2789 * lisp.h (init_foreground_group): New decl.
2790 * sysdep.c (inherited_pgroup): New static var.
2791 (init_foreground_group, tcsetpgrp_without_stopping)
2792 (narrow_foreground_group, widen_foreground_group): New functions.
2793 (init_sys_modes): Narrow foreground group.
2794 (reset_sys_modes): Widen foreground group.
2796 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2798 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2800 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2802 * minibuf.c (read_minibuf): Restore current buffer since
2803 choose_minibuf_frame calling Fset_frame_selected_window may
2804 change it (Bug#12766).
2806 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2808 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2810 2012-10-30 Kenichi Handa <handa@gnu.org>
2812 * font.c (Ffont_at): If WINDOW is specified and it is not
2813 displaying the current buffer, signal an error.
2815 2012-10-29 Daniel Colascione <dancol@dancol.org>
2817 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2818 In preparation for fixing bug#12739, move these functions from
2821 * coding.h, coding.c: ... to here, and compile them only when
2822 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2823 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2825 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2827 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2828 (timer_loop, getitimer, setitimer): Use it instead of
2829 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2831 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2834 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2836 * nsterm.m (NO_APPDEFINED_DATA): New define.

2838 (last_appdefined_event): Remove.
2839 (ns_select): Initialize t from last_appdefined_event_data instead
2840 of [last_appdefined_event data1].
2841 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2842 remove last_appdefined_event (Bug#12698).
2844 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2846 * frame.c (x_set_font): Catch internal error.
2848 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2850 Avoid overflow in w32 implementation of interval timers.
2851 When possible, for ITIMER_PROF count only times the main thread
2853 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2854 'volatile ULONGLONG' types. All the other data which was
2855 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2856 (GetThreadTimes_Proc): New typedef.
2857 (w32_get_timer_time): New function, returns a suitable time value
2859 (timer_loop): Enter critical section when accessing ULONGLONG
2860 values of the itimer_data struct, as these accesses are no longer
2861 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2862 Remove unused variable.
2863 (init_timers): Initialize s_pfn_Get_Thread_Times.
2864 (start_timer_thread): Don't assign itimer->caller_thread here.
2865 (getitimer): Assign itimer->caller_thread here.
2866 (setitimer): Always call getitimer to get the value of ticks_now.
2867 (sys_spawnve): Avoid compiler warning about format mismatch.
2869 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2871 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2872 mouse movement events if the menu bar is active. This avoids
2873 producing a busy "hour-glass" cursor by Windows if the mouse
2874 pointer is positioned over a tooltip shown for some menu item.
2876 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2878 Don't assume process IDs fit in int.
2879 * emacs.c (shut_down_emacs) [!DOS_NT]:
2880 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2881 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2882 Use pid_t, not int, to store process IDs, as 'int'
2883 is not wide enough on a few platforms (e.g., AIX and IRIX).
2885 2012-10-23 Kenichi Handa <handa@gnu.org>
2887 The following change is to make face-font-rescale-alist work
2888 correctly for non-ASCII fonts.
2890 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2891 (font_open_for_lface): Handle Vface_font_rescale_alist.
2893 2012-10-23 Chong Yidong <cyd@gnu.org>
2895 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2897 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2906 2012-10-21 Glenn Morris <rgm@gnu.org>
2908 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2910 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2912 Port to OpenBSD 5.1.
2913 * frame.c (Fmouse_position, Fmouse_pixel_position):
2914 * xdisp.c (produce_stretch_glyph):
2915 Declare local vars only when they're needed.
2916 This is clearer and avoids a warning on OpenBSD about unused vars.

2918 This is safer, and avoids OpenBSD warnings about unused vars.
2919 * keyboard.c (record_menu_key): Remove unnecessary decl.
2920 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2921 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2922 as our definition clashes with OpenBSD's.
2923 * xfaces.c (load_face_colors, check_lface_attrs)
2924 (get_lface_attributes_no_remap, get_lface_attributes)
2925 (lface_fully_specified_p, x_supports_face_attributes_p)
2926 (tty_supports_face_attributes_p, face_fontset, realize_face)
2927 (realize_x_face, realize_tty_face):
2928 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2929 merely Lisp_Object *. This is more informative and avoids
2930 a warning on OpenBSD about accessing beyond an object's size.
2932 2012-10-20 Chong Yidong <cyd@gnu.org>
2934 * lread.c (Fload): Doc fix (Bug#12592).

2960 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2961 (staticpro): If we run out of staticpro slots, die with an
2962 informative error instead of just calling emacs_abort.
2964 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2966 Fix two flaws reported by Dmitry Antipov.
2967 * window.c (Ftemp_output_buffer_show): Remove.

3221 since unsigned is guaranteed to have that behavior and signed is not.

3223 (get_input_pending): Remove first argument, since it was always
3224 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3225 and behave as if it had that value. Return new value of
3226 input_pending. All callers changed.
3227 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3228 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3257 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3259 * commands.h (immediate_quit): Remove duplicate decl.
3261 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3263 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3266 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3268 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3270 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3271 match what GetLastError returns. Explain why the function is
3274 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3275 'is_tooltip_frame', to avoid confusion with its global namesake.
3277 2012-10-08 Daniel Colascione <dancol@dancol.org>
3279 * xdisp.c (start_hourglass): Call w32_note_current_window when
3280 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3281 build that caused Emacs to display the hourglass cursor forever.
3283 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3284 which is broken under remote desktop, calculate the number of
3285 colors available for a display based on the display's number of
3286 planes and number of bits per pixel per plane. (bug#10397).
3288 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3290 * nsfont.m (Vfonts_in_cache): New variable.
3291 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3292 are used. Add cached fonts to Vfonts_in_cache.
3293 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3295 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3297 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3299 (FONT_H): Define after FRAME_H.
3300 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3301 Update dependencies.
3303 * w32term.c: Remove leftover declaration of keyboard_codepage.
3305 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3307 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3308 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3309 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3310 (GLOBAL_SOURCES): Add cygw32.c.
3311 ($(BLD)/unexw32.$(O)):
3313 ($(BLD)/w32console.$(O)):
3314 ($(BLD)/w32fns.$(O)):
3315 ($(BLD)/w32heap.$(O)):
3316 ($(BLD)/w32menu.$(O)):
3317 ($(BLD)/w32proc.$(O)): Add w32common.h.
3319 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3321 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3323 2012-10-08 Daniel Colascione <dancol@dancol.org>
3325 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3326 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3327 accidental message numbering hole. Change other messages to
3330 * w32select.h (HAVE_W32SELECT): Remove.
3332 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3333 w32common.h instead of w32heap.h.
3335 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3336 (get_allocation_unit, get_processor_type, get_w32_major_version)
3337 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3338 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3339 (OS_NT, os_subtype, cache_system_info): Move declarations to
3342 * w32heap.c: Include w32common.h.
3343 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3344 (w32_minor_version, w32_build_number, w32_subtype):
3345 Remove duplicate definitions.
3347 * w32fns.c: Include w32common.h; include w32heap.h only in
3350 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3351 Use `report_file_error' instead of `error' in order to better
3352 inform users of what went wrong. Increase NTGUI_UNICODE file
3353 dialog box file name length to 32k, the maximum allowed by the NT
3356 * w32common.h: New file.
3357 (ROUND_UP, ROUND_DOWN, get_page_size)
3358 (get_allocation_unit, get_processor_type, get_w32_major_version)
3359 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3360 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3361 (OS_NT, os_subtype, cache_system_info): Move here.
3363 * unexw32.c, unexcw.c: Include w32common.h.
3365 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3366 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3367 to call syms_of_w32select.
3369 * cygw32.h: Remove obsolete EXFUN declarations.
3371 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3373 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3374 of w32inevt.o from SOME_MACHINE_OBJECTS.
3376 2012-10-08 Daniel Colascione <dancol@dancol.org>
3378 * image.c: Permanent fix for JPEG compilation issue --- limit
3379 jpeglib `boolean' redefinition to Cygwin builds.
3381 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3383 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3385 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3388 2012-10-08 Daniel Colascione <dancol@dancol.org>
3390 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3391 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3392 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3393 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3394 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3395 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3396 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3397 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3398 now a supported configuration.
3400 * Makefile.in: consolidate image variables into LIBIMAGE; add
3401 W32_OBJ and W32_LIBS. Compile new files.
3404 (_DebPrint) declare tracing facility for W32 debugging. We need
3405 to unify tracing later.
3407 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3408 unconditional use of W32 Unicode functions. Cygwin runs only on
3409 100% Unicode operating systems.
3411 * cygw32.c: New file. Define Cygwin-specific facilities.
3412 (Fcygwin_convert_path_to_windows)
3413 (Fcygwin_convert_path_from_windows): New user functions for
3414 accessing Cygwin path-munging routines.
3416 * cygw32.h: New file.
3417 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3418 UTF-16LE strings temporarily inside non-Lisp-visible string
3421 (w32_strerror): Just what it says on the tin.
3423 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3424 also run for Cygwin; both systems have the same problem with using
3425 GUI facilities in a forked child. Also call syms_of_cygw32,
3426 syms_of_w32select in correct places.
3428 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3429 needs fork-then-exec for daemon launching.
3431 * font.h: Include frame.h.
3433 * image.c: Use the image library cache machinery only when we're
3434 compiling for native WINDOWSNT; Cygwin can use shared libraries
3435 like any other Unixlike system.
3437 * keyboard.c: Clarify a comment regarding the input loop.
3439 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3440 functions directly instead of trying to detect at runtime that our
3441 host operating system supports them. We make this change for two
3442 reasons: Cygwin lacks support for the multibyte character
3443 conversion functions used by the legacy menu code, and Cygwin
3444 never needs to rely on non-Unicode APIs.
3446 * unexw32.c (hinst): Declare extern.
3448 * w32.c: Change header order;
3449 (w32_strerror): Move to w32fns.c because we need it for
3450 non-WINDOWSNT builds.
3452 * w32.h: Add #error macro to make sure we don't include w32.h for
3453 Cygwin builds. Remove w32select declarations.
3455 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3456 w32fns.c. w32console.c is WINDOWSNT-only.
3458 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3459 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3461 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3462 (w32_major_version, w32_minor_version, w32_build_number)
3463 (os_subtype, sound_type): Define here
3464 (w32_defined_color): Make color parameter const for consistency
3465 with other _defined_color functions.
3466 (w32_createwindow): Unconditionally call w32_init_class instead of
3467 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3468 through the code is complex and unnecessary because class
3469 registration is practically free.
3470 (w32_name_of_message): New EMACSDEBUG-only function.
3471 (Fset_message_beep): Move here
3472 (Fx_open_connection): Require that the display name for Windows be
3473 "w32" for consistency, emacsclient disambiguation, and maybe, one
3474 day, multi-window-system support.
3475 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3476 Cygwin files for W32 GUI facilities, since these clearly don't
3477 expect Cygwin names.
3478 (_DebPrint): Define.
3479 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3480 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3481 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3482 (w32_last_error): Remove.
3484 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3486 * w32heap.c (syspage_mask): Declare here.
3487 (cache_system_info): Remove.
3489 * w32inevt.c (faked_key): Define globally, not statically.
3490 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3491 (w32_console_toggle_lock_key): Move to w32fns.c.
3493 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3495 * w32proc.c (_DebPrint): Move to w32fns.c.
3496 * w32select.c: Include string.h, stdio.h for Cygwin.
3497 * w32select.h: New File.
3499 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3501 (w32_message_fd): New variable. Under Cygwin, holds the file
3502 descriptor the system used to tell us about pending thread
3505 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3506 that prevented compilation under non-WINDOWSNT systems.
3508 (w32_initialize): Open /dev/windows and assign it to
3509 w32_message_fd. Provide w32 feature.
3511 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3512 (WM_EMACS_INPUT_READY): add.
3513 (prepend_msg, w32_message_fd): Declare globally.
3516 (keyboard_handle): Use only when WINDOWSNT.
3517 (notify_msg_ready): New function. Posts a message to the main
3518 thread's message queue under CYGWIN, which wakes up the main
3519 thread from select(2) by making the /dev/windows file descriptor
3520 ready. Under WINDOWSNT, it sets an event the same way the old
3523 (post, prepend_msg): Actually call notify_msg_ready instead of
3524 setting the input event directly.
3526 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3528 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3529 but it still has blocs in it, don't return it to the system,
3530 instead of aborting. (Bug#12402)
3532 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3534 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3536 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3537 MAC_OS_X_VERSION_10_6.
3538 (syms_of_nsterm): Remove comment about Panther and above for
3540 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3541 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3542 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3544 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3545 MAC_OS_X_VERSION_10_4.
3547 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3548 MAC_OS_X_VERSION_10_2.
3550 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3552 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3553 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3555 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3556 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3557 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3558 Remove ns_in_resize check.
3559 (ns_clear_frame_area): Remove resize handle code.
3561 * nsfns.m (ns_in_resize): Remove.
3562 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3563 Remove ns_in_resize check.
3565 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3567 Improve sys_siglist detection.
3568 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3569 defined as a macro, as is done in Solaris.
3570 (sys_siglist_entries): New macro.
3571 (save_strsignal): Use it.
3572 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3573 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3575 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3577 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3578 fullscreen/Fullscreen.
3580 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3581 tobar_height is new.
3583 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3584 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3585 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3586 (windowDidResize:): Check for correct window if old style fullscreen.
3587 Capitalize word in comment. Remove incorrect comment.
3588 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3589 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3590 error in drawing background.
3591 (toggleFullScreen:): Remove comment. Rearrange calls.
3592 Set toolbar values to zero, save old height in tobar_height.
3593 Restore tool bar height when leaving fullscreen.
3594 (canBecomeMainWindow): New function.
3596 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3598 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3600 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3602 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3604 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3605 that time stamps of directories could also be changed.
3606 Don't request the too broad GENERIC_WRITE, only the more restrictive
3607 FILE_WRITE_ATTRIBUTES access rights.
3609 * fileio.c (Fset_file_times): Special-case ignoring errors for
3610 directories only on MSDOS, not on MS-Windows.
3612 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3614 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3616 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3618 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3619 see whether CreateFile failed.
3621 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3623 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3624 to avoid similar races.
3625 * keyboard.c (pending_signals): Now bool, not int.
3627 Port timers to OpenBSD, plus check for timer failures.
3628 OpenBSD problem reported by Han Boetes.
3629 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3631 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3632 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3633 like OpenBSD, which has timer_settime but does not declare it.
3634 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3635 whether to use itimerspec-related primitives. All uses of
3636 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3638 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3640 * profiler.c (handle_profiler_signal): Fix a malloc race
3641 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3643 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3645 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3647 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3649 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3650 consistent with the change in return value of 'safe_strsignal'.
3652 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3654 Prefer plain 'static' to 'static inline' (Bug#12541).
3655 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3656 (bidi_set_sor_type, bidi_push_embedding_level)
3657 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3658 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3659 (bidi_cache_search, bidi_cache_ensure_space)
3660 (bidi_cache_iterator_state, bidi_cache_find)
3661 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3662 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3663 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3664 Now 'static', not 'static inline'.
3666 Count overruns when profiling; change units to ns.
3667 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3668 Give extra weight to samples after overruns, to attempt to count
3669 the time more accurately.
3670 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3671 the underlying primitives nominally do ns.
3672 (Fprofiler_cpu_start): Document the change. Mention that
3673 the sampling intervals are only approximate.
3675 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3677 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3679 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3680 case for the special 0 coding-system.
3682 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3683 (Fmake_overlay): Remove redundant tests.
3684 (fix_start_end_in_overlays): Remove redundant recentering.
3686 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3688 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3689 Update dependencies.
3691 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3693 Fix a malloc race condition involving strsignal.
3694 A signal can arrive in the middle of a malloc, and Emacs's signal
3695 handler can invoke strsignal, which can invoke malloc, which is
3696 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3697 Fix it by altering the signal handler so that it does not invoke
3699 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3700 * process.c (status_message): Use const pointer, in case strsignal
3701 is #defined to safe_strsignal.
3702 * sysdep.c (sys_siglist, init_signals): Always define and
3703 initialize a substitute sys_siglist if the system does not define
3704 one, even if HAVE_STRSIGNAL.
3705 (safe_strsignal): Rename from strsignal. Always define,
3706 using sys_siglist. Return a const pointer.
3707 * syssignal.h (safe_strsignal): New decl.
3708 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3710 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3712 * w32proc.c (timer_loop): Fix code that waits for timer
3713 expiration, to avoid high CPU usage.
3715 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3717 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3718 (sweep_weak_table): Remove redundant prototypes.
3720 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3722 * emacs.c: Move the inclusion of TERM_HEADER after including
3723 windows.h on WINDOWSNT. This avoids compilation problems with
3726 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3728 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3729 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3730 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3731 as the previous version used 'void *'.
3733 * ralloc.c (ROUNDUP): Fix last change.
3734 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3737 * w32proc.c <disable_itimers>: New static flag.
3738 (init_timers): Initialize it to zero, after creating the critical
3739 sections used by the timer threads.
3740 (term_timers): Set to 1 before deleting the critical sections.
3741 (getitimer, setitimer): If disable_itimers is non-zero, return an
3742 error indication without doing anything. Reported by Fabrice
3743 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3744 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3746 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3749 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3750 term_ntproc after all the other bookkeeping, to get timers working
3751 as long as possible.
3753 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3755 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3756 Suggested by Juri Linkov in
3757 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3759 Prefer plain 'static' to 'static inline' (Bug#12541).
3760 With static functions, modern compilers inline pretty well by
3761 themselves; advice from programmers often hurts as much as it helps.
3762 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3763 this change shrinks the text size of the Emacs executable by 1.1%
3764 without affecting CPU significantly in my benchmark.
3765 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3845 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3847 Revert the FOLLOW-SYMLINKS change for file-attributes.
3848 Doing it right would require several changes to Tramp, and there's
3849 not enough time to get that tested before the freeze today.
3850 * dired.c (directory_files_internal, Ffile_attributes):
3853 * frame.c (x_report_frame_params): Port better to wider ints.
3854 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3855 or that pointers can be printed in 15 decimal digits.
3856 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3892 * vm-limit.c (lim_data): Now size_t.
3893 (check_memory_limits): Adjust prototypes of real_morecore and
3894 __morecore to receive argument of type ptrdiff_t. Use size_t for

3963 Windows-specific code to display the hourglass mouse pointer is no
3965 (w32_wnd_proc): Remove code that handled the WM_TIMER message due

4047 Profiler improvements: more-accurate timers, overflow checks.
4048 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4049 signal.h, setjmp.h. Include systime.h instead.
4050 (saturated_add): New function.

4057 All uses changed to store the new value.
4058 (handle_profiler_signal): Rename from sigprof_handler_1,
4059 for consistency with other handlers. Do not check whether
4060 cpu_log is a hash-table if garbage collecting, since it
4061 doesn't matter in that case.

4063 for consistency with other handlers.
4064 (setup_cpu_timer): New function, with much of what used to be in
4065 Fprofiler_cpu_start. Check for out-of-range argument.
4066 Prefer timer_settime if available, and prefer
4067 thread cputime clocks, then process cputime clocks, then
4068 monotonic clocks, to the old realtime clock. Use make_timeval
4069 to round more-correctly when falling back to setitimer.
4070 (Fprofiler_cpu_start): Use it.
4071 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4072 Don't assume that passing NULL as the 2nd argument of setitimer
4073 is the same as passing a pointer to all-zero storage.
4074 Ignore SIGPROF afterwards.
4075 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4076 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4077 non-fatal signal handlers. Ignore SIGPROF on startup.
4078 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4079 in profiler.c, since sysdep.c now uses it.
4081 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4137 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4138 Since this stuff is now private to charset.c, there's no need for
4139 a public macro and no need to inline by hand.

4168 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4170 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4172 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4174 Prefer POSIX timers if available.
4175 They avoid a race if the timer is too close to the current time.
4176 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4177 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4178 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4180 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4182 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
4183 CHAR_STRING_ADVANCE.
4184 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
4185 STRING_CHAR_ADVANCE.
4187 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4189 Move Vlibrary_cache to emacs.c and reset before dumping.
4191 * lisp.h (reset_image_types): Declare.
4192 [WINDOWSNT] (Vlibrary_cache): Declare.
4194 * image.c (reset_image_types): New function.
4196 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
4197 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
4198 (Fdump_emacs): Reset Vlibrary_cache and image_types.
4200 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
4201 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
4203 * w32.h (Vlibrary_cache): Do not declare.
4205 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4207 * w32proc.c (sys_signal): Handle all signals defined by the
4208 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4209 handlers for signals supported by Windows. Don't override
4210 term_ntproc as the handler for SIGABRT.
4211 (sigaction): Rewrite to call sys_signal instead of duplicating its
4213 (sys_kill): Improve commentary.
4215 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4216 consistency with a signature of a signal handler. All callers
4218 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4219 install term_ntproc as a signal handler for SIGABRT, as that
4220 should be done by the dumped Emacs.
4222 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4224 * w32select.c (term_w32select): Protect against repeated
4225 invocation by setting clipboard_owner to NULL after calling
4228 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4229 and term_ntproc to their modified signatures.
4231 * character.c (char_string, string_char): Remove calls to
4232 MAYBE_UNIFY_CHAR. See the discussion starting at
4233 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4236 2012-09-25 Chong Yidong <cyd@gnu.org>
4238 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4240 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4242 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4243 when encountering an unknown bytecode.
4245 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4247 image.c, indent.c: Use bool for booleans.
4248 * dispextern.h (struct image_type): Members valid_p, load, init
4249 now return bool, not int. All uses changed.
4250 * image.c: Omit unnecessary static decls.
4251 (x_create_bitmap_mask, x_build_heuristic_mask):
4252 Return void, not int, since callers don't care about the return value.

4281 Use bool for booleans.
4283 2012-09-24 Chong Yidong <cyd@gnu.org>
4285 * chartab.c (Fset_char_table_default): Obsolete function removed.
4287 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4289 Move pid_t related decls out of lisp.h.
4290 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4291 (interruptible_wait_for_termination):
4292 Move these decls from lisp.h to syswait.h, since they use pid_t.
4293 Needed on FreeBSD; see Herbert J. Skuhra in
4294 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4295 * callproc.c: Include syswait.h.

4312 * nsmenu.m (ns_update_menubar):
4313 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4314 * xfns.c (Fx_show_tip) [USE_GTK]:
4315 Use bool for boolean.
4316 * gtkutil.c (xg_update_frame_menubar):
4317 * xmenu.c (update_frame_menubar):
4318 Return void, not int, since caller ignores return value.
4319 * gtkutil.c (xg_change_toolbar_position):
4322 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4324 * makefile.w32-in (BLOCKINPUT_H): Remove.

4341 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4343 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4344 fatal_error_backtrace.
4346 * w32proc.c (sys_kill): Undo last change: don't do anything when
4347 invoked to deliver SIGABRT to our own process. This is now
4348 handled by emacs_raise.
4350 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4352 * w32term.c (w32_read_socket): Remove leftover reference to
4353 interrupt_input_pending.
4355 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4357 Do not use SA_NODEFER.
4358 Problem reported by Dani Moncayo in
4359 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4361 * sysdep.c (emacs_abort): Do not reset signal handler.
4362 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4363 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4364 wanted even on POSIXish hosts, and it doesn't work on Windows.
4366 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4368 * xterm.c (x_term_init): Call fixup_locale before and after calling
4369 gtk_init (Bug#12392).
4371 2012-09-23 Chong Yidong <cyd@gnu.org>
4373 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4374 Vdynamic_library_alist.
4376 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4377 (Fgnutls_available_p): Caller changed.
4379 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4380 (Flibxml_parse_xml_region): Likewise.
4382 * dispextern.h (struct image_type): Remove arg from init function.
4384 * image.c (Finit_image_library, lookup_image_type)
4385 (define_image_type): Remove now-unneeded second arg.
4386 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4387 (init_tiff_functions, init_gif_functions, init_svg_functions):
4388 Arglist and w32_delayed_load calling convention changed.
4389 (gs_type): Remove init_gs_functions; there is no such function.
4390 (valid_image_p, make_image): Fix caller to lookup_image_type.
4392 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4394 Simplify and avoid signal-handling races (Bug#12471).
4396 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4397 Avoid recursive loop if there's a fatal error in the function itself.
4398 * atimer.c (pending_atimers):
4399 * blockinput.h: Don't include "atimer.h"; no longer needed.
4400 (interrupt_input_pending): Remove. All uses removed.
4401 pending_signals now counts both atimers and ordinary interrupts.
4402 This is less racy than having three separate pending-signal flags.
4403 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4405 Rename from their upper-case counterparts BLOCK_INPUT,
4406 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4407 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4408 This makes it easier to access volatile variables more accurately.
4409 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4410 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4411 that's more reliable if the code is buggy and sets
4412 interrupt_input_blocked to a negative value. All uses changed.
4413 * atimer.c (deliver_alarm_signal):
4414 Remove. No need to deliver this to the parent; any thread can
4415 handle this signal now. All uses replaced by underlying handler.
4416 * atimer.c (turn_on_atimers):
4417 * dispnew.c (handle_window_change_signal):
4418 * emacs.c (handle_danger_signal):
4419 * keyboard.c (kbd_buffer_get_event):
4420 Don't reestablish signal handler; not needed with sigaction.
4421 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4423 Rework to avoid unnecessary accesses to volatile variables.
4424 (UNBLOCK_INPUT_TO): Now a function.
4425 (totally_unblock_input, unblock_input): New decls.
4426 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4427 (init_data): Remove. Necessary stuff now done in init_signal.
4428 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4429 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4430 (fatal_error_code): Remove; no longer needed.
4431 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4432 it doesn't always backtrace. All uses changed. No need to reset
4433 signal to default, since sigaction and/or die does that for us now.
4434 Use emacs_raise (FOO), not kill (getpid (), FOO).
4435 (main): Check more-accurately whether we're dumping.
4436 Move fatal-error setup to sysdep.c
4437 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4438 * gtkutil.c (xg_get_file_name, xg_get_font):
4439 Remove no-longer-needed signal-mask manipulation.
4440 * keyboard.c, process.c (POLL_FOR_INPUT):
4441 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4442 * keyboard.c (read_avail_input): Remove.
4443 All uses replaced by gobble_input.
4444 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4445 (kbd_buffer_store_event_hold, gobble_input):
4446 (record_asynch_buffer_change) [USABLE_SIGIO]:
4447 (store_user_signal_events):
4448 No need to mess with signal mask.
4449 (gobble_input): If blocking input and there are terminals, simply
4450 set pending_signals to 1 and return. All hooks changed to not
4451 worry about whether input is blocked.
4452 (process_pending_signals): Clear pending_signals before processing
4453 them, in case a signal comes in while we're processing.
4454 By convention callers now test pending_signals before calling us.
4455 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4456 New functions, to support changes to blockinput.h.
4457 (handle_input_available_signal): Now extern.
4458 (reinvoke_input_signal): Remove. All uses replaced by
4460 (quit_count): Now volatile, since a signal handler uses it.
4461 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4462 All callers changed. Block SIGINT only if not already blocked.
4463 Clear sigmask reliably, even if Fsignal returns, which it can.
4464 Omit unnecessary accesses to volatile var.
4465 (quit_throw_to_read_char): No need to restore sigmask.
4466 * keyboard.c (gobble_input, handle_user_signal):
4467 * process.c (wait_reading_process_output):
4468 Call signal-handling code rather than killing ourselves.
4469 * lisp.h: Include <float.h>, for...
4470 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4471 (pending_signals): Now volatile.
4472 (syms_of_data): Now const if IEEE floating point.
4473 (handle_input_available_signal) [USABLE_SIGIO]:
4474 (terminate_due_to_signal, record_child_status_change): New decls.
4475 * process.c (create_process): Avoid disaster if memory is exhausted
4476 while we're processing a vfork, by tightening the critical section
4478 (send_process_frame, process_sent_to, handle_pipe_signal)
4479 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4481 (send_process): No need for setjmp/longjmp any more, since the
4482 SIGPIPE stuff is now gone. Instead, report an error if errno
4484 (record_child_status_change): Now extern. PID and W are now args.
4485 Return void, not bool. All callers changed.
4486 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4487 Remove. All uses removed. This bug should be fixed now in a
4489 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4490 and record the child status change directly. This avoids the
4491 need to futz with the signal mask.
4492 (process_fatal_action): Move here from emacs.c.
4493 (emacs_sigaction_flags): New function, containing
4494 much of what used to be in emacs_sigaction_init.
4495 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4496 caught by emacs, to make races less likely.
4497 (deliver_process_signal): Rename from handle_on_main_thread.
4499 (BACKTRACE_LIMIT_MAX): Now at top level.
4500 (thread_backtrace_buffer, threadback_backtrace_pointers):
4502 (deliver_thread_signal, deliver_fatal_thread_signal):
4503 New functions, for more-accurate delivery of thread-specific signals.
4504 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4505 (deliver_arith_signal): Handle in this thread, not
4506 in the main thread, since it's triggered by this thread.
4507 (maybe_fatal_sig): New function.
4508 (init_signals): New arg DUMPING so that we can be more accurate
4509 about whether we're dumping. Caller changed.
4510 Treat thread-specific signals differently from process-general signals.
4511 Block all signals while handling fatal error; that's safer.
4512 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4514 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4515 Ignore SIGPIPE unless batch.
4516 (emacs_backtrace): Output backtrace for the appropriate thread,
4517 which is not necessarily the main thread.
4518 * syssignal.h: Include <stdbool.h>.
4519 (emacs_raise): New macro.
4520 * xterm.c (x_connection_signal): Remove; no longer needed
4521 now that we use sigaction.
4522 (x_connection_closed): No need to mess with sigmask now.
4523 (x_initialize): No need to reset SIGPIPE handler here, since
4524 init_signals does this for us now.
4526 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4528 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4529 background rect may be larger (Bug#12245).
4531 2012-09-23 Chong Yidong <cyd@gnu.org>
4533 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4535 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4537 * .gdbinit: Just stop at fatal_error_backtrace.
4538 See Stefan Monnier's request in
4539 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4540 Remove no-longer-used query of system type.
4542 2012-09-22 Chong Yidong <cyd@gnu.org>
4544 * search.c (Freplace_match): Doc fix (Bug#12325).
4546 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4548 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4549 (Fline_end_position): Doc fix.
4551 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4553 2012-09-22 Chong Yidong <cyd@gnu.org>
4555 * dispextern.h (struct image_type): Add new slot, storing a type
4556 initialization function.
4558 * image.c (define_image_type): Call the image initializer function
4559 if it is defined. Arguments and return value changed.
4560 (valid_image_p, make_image): Callers changed.
4561 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4562 (gif_type, imagemagick_type, svg_type, gs_type):
4563 Add initialization functions.
4564 (Finit_image_library): Call lookup_image_type.
4565 (CHECK_LIB_AVAILABLE): Macro deleted.
4566 (lookup_image_type): Call define_image_type here, rather than via
4567 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4568 (syms_of_image): Move define_image_type calls for xbm_type and
4569 pbm_type to lookup_image_type.
4571 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4573 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4574 'idle_timers' from here ...
4575 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4576 lists, to avoid infloops when the timer does something stupid,
4577 like reinvoke itself with the same or smaller time-out.
4580 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4582 * window.c (Fsplit_window_internal): Handle only Qt value of
4583 Vwindow_combination_limit separately.
4584 (Qtemp_buffer_resize): New symbol.
4585 (Vwindow_combination_limit): New default value.
4588 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4590 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4591 the new overlay string. (Bug#10159)
4593 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4595 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4596 or that fprintf is async-signal-safe. POSIX doesn't require
4599 2012-09-22 Chong Yidong <cyd@gnu.org>
4601 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4604 2012-09-22 Kenichi Handa <handa@gnu.org>
4606 * composite.c (composition_reseat_it): Handle the case that a
4607 grapheme cluster is not covered by a single font (Bug#12352).
4609 2012-09-21 Chong Yidong <cyd@gnu.org>
4611 * image.c (define_image_type): Avoid adding duplicate types to
4612 image_types (Bug#12463). Suggested by Jörg Walter.
4614 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4616 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4617 (print_load_command_name): Add case LC_DATA_IN_CODE.
4618 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4620 2012-09-21 Glenn Morris <rgm@gnu.org>
4622 * eval.c (Frun_hook_with_args_until_success)
4623 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4625 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4627 * fileio.c (Ffile_selinux_context): Only call freecon when
4628 lgetfilecon succeeded.
4629 (Fset_file_selinux_context): Likewise. (Bug#12444)
4631 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4633 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4634 reordering, locate the cursor by calling set_cursor_from_row; if
4635 that fails, clear the desired glyph matrix before returning a
4636 failure indication to the caller. Fixes leaving garbled display
4637 when fast scrolling with a down-key. (Bug#12403)
4638 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4639 scrolling through multibyte text.
4641 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4643 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4644 calling mark_vectorlike since that's the one that marks the window.
4645 (mark_discard_killed_buffers): Mark the final cdr.
4646 * window.h (struct window): Move prev/next_buffers to the
4647 non-standard fields.
4648 * window.c (make_window): Initialize prev/next_buffers manually.
4650 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4652 Omit unused arg EXPECTED from socket hooks.
4653 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4654 * nsterm.m (ns_term_init):
4655 * termhooks.h (struct terminal.read_socket_hook):
4656 * w32inevt.c (w32_console_read_socket):
4657 * w32term.c (w32_read_socket):
4658 * xterm.c (XTread_socket):
4659 Omit unused arg EXPECTED. All callers changed.
4660 (store_user_signal_events): Return void, not int, since callers no
4661 longer care about the return value. All uses changed.
4663 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4665 * w32gui.h (XParseGeometry): Do not declare.
4667 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4669 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4670 Ignore 'expected'. See Eli Zaretskii in
4671 <http://bugs.gnu.org/12471#8> (last line).
4673 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4674 (XParseGeometry): Now static. Substitute extremal values for
4675 values that are out of range.
4677 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4679 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4681 * nsfns.m (XParseGeometry): Remove.
4682 (Fx_create_frame): Call x_set_offset to correctly interpret
4683 top_pos in geometry.
4685 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4686 (Fx_parse_geometry): If there is a space in string, call
4687 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4689 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4691 * search.c (scan_buffer): Use character positions in calls to
4692 region_cache_forward and region_cache_backward, not byte
4693 positions. (Bug#12196)
4695 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4696 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4698 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4699 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4700 emacs_blocked_malloc, now deleted.
4702 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4704 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4705 The workaround was for improving performance on Solaris 2.4, but
4706 is getting in the way now. Emacs will still work if someone is
4707 still running Solaris 2.4 in a museum somewhere; Sun dropped
4708 support for Solaris 2.4 in 2003.
4709 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4710 * process.c (create_process) [HAVE_WORKING_VFORK]:
4711 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4712 since Emacs no longer uses vfork on that platform.
4714 2012-09-17 Glenn Morris <rgm@gnu.org>
4716 * emacs.c: Use COPYRIGHT.
4718 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4720 Remove configure's --without-sync-input option (Bug#12450).
4721 When auditing signal-handling in preparation for cleaning it up,
4722 I found that SYNC_INPUT has race conditions and would be a real
4723 pain to fix. Since it's an undocumented and deprecated
4724 configure-time option, now seems like a good time to remove it.
4725 Also see <http://bugs.gnu.org/11080#16>.
4726 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4727 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4728 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4729 (malloc_hysteresis):
4730 (check_depth) [XMALLOC_OVERRUN_CHECK]:

4734 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4735 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4736 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4737 Remove. All uses removed.
4738 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4739 implementation, one that depends on whether the new macro
4740 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4742 * atimer.c (run_timers, handle_alarm_signal):
4743 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4744 (handle_async_input, process_pending_signals)
4745 (handle_input_available_signal, init_keyboard):
4746 * nsterm.m (ns_read_socket):
4747 * process.c (wait_reading_process_output):
4748 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4749 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4751 * xterm.c (XTread_socket):
4753 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4754 * eval.c (handling_signal): Remove. All uses removed.
4755 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4756 All uses replaced with the SYNC_INPUT version.
4757 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4759 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4762 * font.c (Ffont_shape_gstring): Remove unused local.
4764 2012-09-16 Glenn Morris <rgm@gnu.org>
4766 * Makefile.in (clean): No longer run nextstep's clean.
4768 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4770 (ns-app): Move here from ns.mk, and simplify.
4771 (clean): Simplify nextstep entry.
4772 * ns.mk: Remove file.
4774 2012-09-17 Kenichi Handa <handa@gnu.org>
4776 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4777 not covert the last few charactes.
4779 2012-09-16 Kenichi Handa <handa@gnu.org>
4781 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4782 here, but just check the validity of glyphs in the glyph-string.
4784 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4786 * window.c (Fwindow_parameter, Fset_window_parameter):
4787 Accept any window as argument (Bug#12452).
4789 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4791 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4792 to ns_term_init to avoid memory leak.
4794 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4795 explicit retain/release.
4796 (ns_term_init): Only allow one display. Initialize outerpool and
4799 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4801 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4802 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4803 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4804 the Microsoft problem in a different way, by altering ../nt/config.nt.
4806 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4821 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4822 by lisp.h. This completes removal of setjmp.h inclusion
4823 erroneously announced in the previous commit. (Bug#12446)
4825 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4828 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4829 not defined as a macro. The latter happens on MS-Windows.
4832 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4834 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4835 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4836 Some instances of '#include <setjmp.h>' removed, if the
4837 only reason for the instance was because "lisp.h" was included.
4838 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4839 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4840 and _longjmp with the new symbols. Emacs already uses _setjmp if
4841 available, so this change affects only POSIXish hosts that have
4842 sigsetjmp but not _setjmp, such as some versions of Solaris and
4843 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4844 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4845 (png_load_body) [HAVE_PNG]:
4846 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4847 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4848 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4849 since PNG requires jmp_buf. This is the only exception to the
4850 general rule that we now use sys_setjmp and sys_longjmp.
4851 This exception is OK since this code does not change the signal
4852 mask or longjmp out of a signal handler.
4854 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4856 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4857 Include "syssignal.h", for 'main_thread'.
4859 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4861 Avoid out-of-range marker position (Bug#12426).
4862 * insdel.c (replace_range, replace_range_2):
4863 Adjust markers before overlays, as suggested by comments.
4864 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4865 Remove redundant check before calling offset_intervals.
4867 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4869 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4870 current buffer (Bug#12387).
4872 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4874 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4876 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4878 Use a more backwards-compatible timer format (Bug#12430).
4879 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4880 vector element, not from the 4th, since PSECS is now at the end.
4881 (Fcurrent_idle_time): Doc fix.
4883 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4885 Function to mark objects and remove killed buffers at once.
4886 * alloc.c (discard_killed_buffers): Rename to ...
4887 (mark_discard_killed buffers) ... new name. Add marking
4888 of remaining objects. Fix comment. Adjust users.
4889 (mark_object): Do not touch frame buffer lists here.
4890 * frame.c (delete_frame): Reset frame buffer lists here.
4892 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4894 Better workaround for GNOME bug when --enable-gcc-warnings.
4895 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4896 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4897 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4899 Simplify SIGIO usage (Bug#12408).
4900 The code that dealt with SIGIO was crufty and confusing, e.g., it
4901 played tricks like "#undef SIGIO" but these tricks were not used
4902 consistently. Simplify mostly by not #undeffing standard symbols,
4903 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4904 or not as we please) rather than "defined SIGIO" (standard symbol
4905 that we probably shouldn't #undef).
4906 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4907 Modules that need it can include it.
4908 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4909 * dispextern.h (ignore_sigio): New decl.
4910 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4911 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4912 * emacs.c (shut_down_emacs):
4913 * keyboard.c (kbd_buffer_store_event_hold):
4914 Use ignore_sigio rather than invoking 'signal' directly.
4915 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4917 (FIONREAD, SIGIO): Do not #undef.
4918 (tty_read_avail_input): Use #error rather than a syntax error.
4919 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4920 for I_PIPE, used by SETUP_SLAVE_PTY.
4921 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4922 * sysdep.c (croak): Remove; no longer needed. This bit of
4923 temporary code, with Fred N. Fish's comment that it's temporary,
4924 has been in Emacs since at least 1992!
4925 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4926 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4927 * syssignal.h (croak): Remove decl.
4928 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4929 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4930 now that we're termios-only.
4931 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4932 * term.c (dissociate_if_controlling_tty): Use #error rather than
4935 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4936 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4937 to work around GNOME bug 683906.
4938 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4939 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4940 This works around GCC bug 54561.
4942 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4944 More fixes for 'volatile' and setjmp/longjmp.
4945 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4946 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4947 (png_load_body) [HAVE_PNG]:
4948 (jpeg_load_body) [HAVE_JPEG]:
4949 New function, with most of the old parent function's body.
4950 (png_load) [HAVE_PNG]:
4951 (jpeg_load) [HAVE_JPEG]:
4952 Invoke the new function, to avoid longjmp munging our locals.
4953 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4954 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4955 longjmp is passed 2, as the C standard doesn't guarantee this.
4956 Instead, store the failure code into mgr->failure_code.
4958 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4960 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4961 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4962 (syms_of_keyboard): Remove support for unread-command-char.
4964 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4966 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4967 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4968 violation. (Bug#12426)
4970 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4972 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4974 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4976 * eval.c: Add `inhibit-debugger'.
4977 (Qinhibit_debugger): New symbol.
4978 (call_debugger): Bind it instead of Qdebug_on_error.
4979 (maybe_call_debugger): Test Vinhibit_debugger.
4980 (syms_of_eval): Define inhibit-debugger.
4981 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4982 (syms_of_xdisp): Remove inhibit-debug-on-message.
4984 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4986 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4987 If a nonvolatile local variable is written before a _longjmp to
4988 the frame containing the variable, and is read after the _longjmp,
4989 the value read is indeterminate. Some local variables of type
4990 'struct handler' and 'struct catchtag' are used in this way, so
4991 mark each of their slots as volatile if the slot can be set before
4992 _longjmp and read afterwards.
4993 * lisp.h (struct handler): var and chosen_clause are now volatile.
4994 (struct catchtag): val, next, and pdlcount are now volatile.
4996 * bidi.c (bidi_push_it, bidi_pop_it):
4997 * fns.c (copy_hash_table):
4998 * image.c (define_image_type):
4999 * keyboard.c (kbd_buffer_store_event_hold):
5000 * process.c (Fprocess_send_eof):
5001 * xfaces.c (x_create_gc) [HAVE_NS]:
5002 * xgselect.c (xg_select):
5003 Prefer assignment to memcpy when either will do.
5005 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5006 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5007 time an item is removed. No need to mark this function 'inline';
5008 the compiler knows better than we do.
5010 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5012 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5013 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5014 to change_frame_size (Bug#12388).
5015 (windowDidResize:): Pass YES to updateFrameSize.
5017 * nsterm.h: Add delay parameter to updateFrameSize.
5019 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5021 Discard killed buffers from deleted window and frame objects.
5022 This reduces an amount of references to killed buffers and
5023 helps GC to reclaim them faster.
5024 * alloc.c (discard_killed_buffers): New function.
5025 (mark_object): Use it for deleted windows and frames.
5026 (mark_object): If symbol's value is set up for a killed buffer
5027 or deleted frame, restore its global binding.
5028 * data.c (swap_in_global_binding): Add GC notice.
5029 (swap_in_symval_forwarding): Use convenient set_blv_where.
5030 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5031 * window.h: ... to here.
5033 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5035 Convenient macro to check whether the buffer is live.
5036 * buffer.h (BUFFER_LIVE_P): New macro.
5037 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5038 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5040 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5042 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5043 composition cases (Bug#12364).
5045 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5046 overhang of succeeding glyphs overlapping box cursor.
5048 * w32term.c (x_draw_glyph_string): Likewise.
5050 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5052 Simplify, document, and port floating-point (Bug#12381).
5053 The porting part of this patch fixes bugs on non-IEEE platforms
5054 with frexp, ldexp, logb.
5055 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5057 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5058 support, by removing commented-out code and briefly listing the
5059 C89 functions excluded. The commented-out stuff was confusing
5060 maintenance, e.g., we thought we needed cbrt but it was commented out.
5061 (logb): Remove decl; no longer needed.
5062 (isfinite): New macro, if not already supplied.
5063 (isnan): Don't replace any existing macro.
5064 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5065 are present on all C89 platforms.
5066 (Ffrexp): Do not special-case zero, as frexp does the right thing
5068 (Flogb): Do not use logb, as it doesn't have the desired meaning
5069 on hosts that use non-base-2 floating point. Instead, stick with
5070 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5071 frexp, to avoid getting an unspecified result.
5073 * xdisp.c (Qinhibit_debug_on_message): Now static.
5075 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5077 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5078 NSBezierPath (Bug#12131).
5080 2012-09-10 Chong Yidong <cyd@gnu.org>
5082 * fns.c (Fdelq, Fdelete): Doc fix.
5084 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5086 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5087 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5089 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5091 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5092 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5095 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5097 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5098 left fringe if the window has a left margin. This avoids leaving
5099 traces of the cursor because its leftmost pixel is not drawn over.
5101 * dispnew.c (update_window_line): When the left margin area of a
5102 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5103 that screen line. (Bug#12277)
5105 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5107 Assume C89 or later for math functions (Bug#12381).
5108 This simplifies the code, and makes it a bit smaller and faster,
5109 and (most important) makes it easier to clean up signal handling
5110 since we can stop worring about floating-point exceptions in
5111 library code. That was a problem before C89, but the problem
5112 went away many years ago on all practical Emacs targets.
5113 * data.c, image.c, lread.c, print.c:
5114 Don't include <math.h>; no longer needed.
5115 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5116 might be autoconfigured, as that never happens.
5118 * doprnt.c (DBL_MAX_10_EXP):
5119 * print.c (DBL_DIG):
5120 Remove. C89 or later always defines these.
5121 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5122 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5123 (arith_error, domain_error, domain_error2):
5124 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5125 no longer needed -- we simply return what C returns. All uses removed.
5126 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5128 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5129 Remove. All uses expanded, as these macros are no longer used
5130 more than once and are now more trouble than they're worth.
5131 (Ftan): Use tan, not sin / cos.
5132 (Flogb): Assume C89 frexp.
5133 (fmod_float): Assume C89 fmod.
5134 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5135 (init_floatfns): Remove. All uses removed.
5137 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5139 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5140 compositeToPoint for OSX < 10.6 (Bug#12390).
5142 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5144 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5145 This produces more-accurate results.
5147 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5149 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5150 changes (Bug#12088).
5152 2012-09-08 Chong Yidong <cyd@gnu.org>
5154 * syntax.c (Fstring_to_syntax): Doc fix.
5156 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5158 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5159 in the internal border.
5160 (x_set_window_size): Remove static variables and their usage.
5161 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5162 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5163 Remove fringe/internal border adjustment (Bug#11052).
5164 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5165 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5166 (ns_fix_rect_ibw): Remove.
5167 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5168 (ns_dumpglyphs_box_or_relief): Ditto.
5169 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5171 (ns_dumpglyphs_image): Ditto.
5172 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5174 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5175 their usage. Add fringe_extended_p and its use as in other terms.
5176 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5177 scroll bar was removed.
5178 (updateFrameSize): New function.
5179 (windowDidResize): Move code to updateFrameSize and call it.
5181 * nsterm.h (EmacsView): Add updateFrameSize.
5183 2012-09-07 Chong Yidong <cyd@gnu.org>
5185 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5187 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5189 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5191 More signal-handler cleanup (Bug#12327).
5192 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5193 Problem introduced when merging patches. Noted by Eli Zaretskii in
5194 <http://bugs.gnu.org/12327#67>.
5195 * floatfns.c: Comment fix.
5196 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5197 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5198 and anyway the declaration is harmless even if SIGDANGER is not defined.
5199 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5200 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5201 source files not surprisingly expected syssignal.h to define, or
5202 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5203 Include <sys/ioctl.h>, for FIONREAD.
5204 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5205 This eliminates a problem whereby other files mysteriously had
5206 to include "syssignal.h" before including "systty.h" if they
5207 wanted to use "#ifdef SIGIO".
5209 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5211 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5213 * w32.c (sigemptyset): Empty the set.
5214 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5216 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5218 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5220 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5221 (mark_object): Likewise for frame objects.
5223 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5225 * syssignal.h (handle_on_main_thread): Always declare,
5226 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5227 This ports to platforms without HAVE_PTHREAD.
5229 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5231 Signal-handler cleanup (Bug#12327).
5232 Emacs's signal handlers were written in the old 4.2BSD style with
5233 sigblock and sigmask and so forth, and this led to some
5234 inefficiencies and confusion. Rewrite these to use
5235 pthread_sigmask etc. without copying signal sets around. Also,
5236 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5237 'signal', and instead use functions that do not attempt to take
5238 over the system name space. This patch causes Emacs's text
5239 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5240 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5241 Do not include <signal.h> or "syssignal.h", as these
5242 modules do not use signals.
5243 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5244 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5245 Do not include <signal.h>, as "syssignal.h" does that for us now.
5246 * atimer.c (sigmask_atimers): New function.
5247 (block_atimers, unblock_atimers): New functions,
5248 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5250 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5251 no longer needed here.
5252 * emacs.c (main): Inspect existing signal handler with sigaction,
5253 so that there's no need to block and unblock SIGHUP.
5254 * sysdep.c (struct save_signal): New member 'action', replacing
5255 old member 'handler'.
5256 (save_signal_handlers, restore_signal_handlers):
5257 Use sigaction instead of 'signal' to save and restore.
5258 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5259 New function. All users of 'signal' modified to use set_sighandler
5260 if they're writeonly, and to use sys_signal if they're read+write.
5261 (emacs_sigaction_init, forwarded_signal): New functions.
5262 (sys_signal): Remove. All uses replaced by calls to sigaction
5263 and emacs_sigaction_init, or by direct calls to 'signal'.
5264 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5265 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5266 all uses replaced by pthread_sigmask etc. calls.
5267 * syssignal.h: Include <signal.h>.
5268 (emacs_sigaction_init, forwarded_signal): New decls.
5269 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5270 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5271 (sigmask, sys_sigmask): Remove; no longer needed.
5272 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5273 (sigblock, sigunblock, sigfree):
5274 (sigsetmask) [!defined sigsetmask]:
5275 Remove. All uses replaced by pthread_sigmask.
5276 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5277 no longer need to be replaced, and its typical old uses
5278 are now done via emacs_sigaction_init and sigaction.
5279 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5280 (sys_sigdel): Remove; unused.
5281 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5283 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5285 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5286 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5288 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5290 Explicitly mark buffer_defaults and buffer_local_symbols.
5291 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5292 mark_local_symbols here.
5293 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5294 since special buffers aren't marked here any more.
5295 (allocate_buffer): Chain new buffer with all_buffers here...
5296 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5298 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5299 (syms_of_buffer): Remove staticpro of the above.
5300 (init_buffer_once): Set names for buffer_defaults and
5301 buffer_local_symbols.
5303 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5305 Use bool for booleans in font-related modules.
5306 * font.c (font_intern_prop, font_style_to_value)
5307 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5308 (generate_otf_features, font_check_otf_features, font_check_otf)
5309 (font_match_p, font_list_entities, font_at):
5310 * fontset.c (fontset_id_valid_p, reorder_font_vector
5311 (fontset_find_font, Fset_fontset_font)
5312 (face_suitable_for_char_p) [0]:
5313 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5314 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5315 (m17n_flt_initialized, ftfont_shape_by_flt):
5316 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5317 * nsfont.m (nsfont_draw):
5318 * w32font.c (w32font_draw):
5319 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5320 Use bool for booleans.
5321 * font.h: Adjust to above API changes.
5322 (struct font, struct font_driver, struct font_driver_list):
5323 Use bool for booleans.
5324 (struct font): Remove useless member encoding_type.
5326 * fontset.c, xftfont.c: Omit unnecessary static decls.
5328 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5330 * alloc.c (mark_object): Revert window marking code
5331 since it's unsafe for the Fset_window_configuration.
5333 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5335 Fix race conditions with signal handlers and errno (Bug#12327).
5336 Be more systematic about preserving errno whenever a signal
5337 handler returns, even if it's not in the main thread. Do this by
5338 renaming signal handlers to distinguish between signal delivery
5339 and signal handling. All uses changed.
5340 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5341 * data.c (deliver_arith_signal): Rename from arith_error.
5342 * dispnew.c (deliver_window_change_signal): Rename from
5343 window_change_signal.
5344 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5345 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5346 * keyboard.c (deliver_input_available_signal): Rename from
5347 input_available_signal.
5348 (deliver_user_signal): Rename from handle_user_signal.
5349 (deliver_interrupt_signal): Rename from interrupt_signal.
5350 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5351 (deliver_child_signal): Rename from sigchld_handler.
5352 * atimer.c (handle_alarm_signal):
5353 * data.c (handle_arith_signal):
5354 * dispnew.c (handle_window_change_signal):
5355 * emacs.c (handle_fatal_signal, handle_danger_signal):
5356 * keyboard.c (handle_input_available_signal):
5357 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5358 * process.c (handle_pipe_signal, handle_child_signal):
5359 New functions, with the actual signal-handling code taken from the
5360 original respective signal handlers, sans the sporadic attempts to
5361 preserve errno, since that's now done by handle_on_main_thread.
5362 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5363 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5364 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5366 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5367 Move initialization of main_thread to sysdep.c's init_signals.
5368 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5369 our usage, and simplifies the mainline code.
5370 (record_child_status_change): New static function, as a helper
5371 for handle_child_signal, and with most of the old child handler's
5373 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5374 (handle_child_signal): Use the above.
5375 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5376 Moved here from emacs.c.
5377 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5378 code moved here from emacs.c's main function.
5379 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5380 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5381 This lets callers save and restore errno properly.
5383 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5385 Remove redundant or unused things here and there.
5386 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5387 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5388 * editfns.c (Fcompare_buffer_substrings): Likewise.
5389 * frame.h (struct terminal, struct font_driver_list):
5390 Remove redundant declarations.
5391 * window.h (Qleft, Qright): Likewise.
5393 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5395 Do not mark objects from deleted buffers, windows and frames.
5396 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5397 (mark_object): Likewise for windows and frames.
5399 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5401 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5402 buffer_defaults and buffer_local_symbols as valid objects.
5403 Return special value to denote them.
5405 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5407 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5408 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5409 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5410 (file_name_absolute_p, Fsubstitute_in_file_name):
5411 (check_executable, check_writable, Ffile_accessible_directory_p)
5412 (Fset_file_selinux_context, Fdefault_file_modes)
5413 (Finsert_file_contents, choose_write_coding_system)
5414 (Fwrite_region, build_annotations, a_write, e_write)
5416 * filelock.c (boot_time_initialized, get_boot_time)
5417 (get_boot_time_1, lock_file_1, within_one_second):
5418 * floatfns.c (in_float):
5419 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5420 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5421 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5422 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5423 * window.c (compare_window_configurations):
5424 Use bool for booleans.
5425 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5426 (Fdefault_file_modes): Now mode_t, not int, for modes.
5427 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5428 (internal_delete_file): Now returns void, not a (boolean) int,
5429 since nobody was looking at the return value.
5430 * lisp.h, window.h: Adjust to above API changes.
5432 * xdisp.c (set_message): Simplify and reindent last change.
5434 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5436 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5438 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5440 * eval.c (call_debugger): Make the function non-static so that we
5441 can call it from set_message.
5443 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5444 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5446 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5448 Give more-useful info on a fatal error (Bug#12328).
5449 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5450 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5451 of doing the work ourselves.
5452 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5453 do most of the work.
5454 (fatal_error_backtrace): New function, taken from the guts
5455 of the old fatal_error_signal, but with a new option to output
5457 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5458 info about the signal than just its number.
5459 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5460 * sysdep.c: Include <execinfo.h>
5461 (emacs_backtrace): New function, taken partly from the previous
5462 code of the 'die' function.
5463 (emacs_abort): Call fatal_error_backtrace rather than abort.
5465 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5467 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5468 eager (load-time) macro-expansion.
5469 * lisp.mk (lisp): Add macroexp.
5471 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5473 Simplify redefinition of 'abort' (Bug#12316).
5474 Do not try to redefine the 'abort' function. Instead, redo
5475 the code so that it calls 'emacs_abort' rather than 'abort'.
5476 This removes the need for the NO_ABORT configure-time macro
5477 and makes it easier to change the abort code to do a backtrace.
5478 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5479 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5480 Remove; sysdep.c's emacs_abort now takes its place.
5481 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5482 'abort' changed to use 'emacs_abort'.
5483 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5484 (abort) [!defined abort]: Rename to ...
5485 (emacs_abort): ... new name.
5486 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5487 the place of the old 'abort' in emacs.c.
5488 * w32.c, w32fns.c (abort): Do not #undef.
5489 * w32.c (emacs_abort): Rename from w32_abort.
5491 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5493 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5494 offsets[j].dv, since the y axis of the screen coordinates points
5495 down, while the y axis of the font definition coordinates points
5496 up. This fixes display of Arabic diacritics such as KASRA and
5497 KASRATAN. (Bug#11860)
5499 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5501 Be more systematic about _setjmp vs setjmp.
5502 * alloc.c (test_setjmp, mark_stack):
5503 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5504 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5505 (png_load, my_error_exit, jpeg_load):
5506 * process.c (send_process_trap, send_process):
5507 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5508 The underscored versions are up to 30x faster on some hosts.
5509 Formerly, the code used setjmp+longjmp sometimes and
5510 _setjmp+_longjmp at other times, with no particular reason to
5511 prefer setjmp+longjmp.
5513 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5515 Fix minor problem found by static checking.

5545 won't change, instead of the address of 'initialize', whose
5546 signature just changed from int to bool.
5547 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5548 * msdos.c (fatal_error_in_progress): ... from here.
5549 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5551 (redisplay_internal, unwind_redisplay): Simply clear
5552 REDISPLAYING_P when unwinding, instead of saving its previous,
5553 always-false value and then restoring it.
5555 Clean up some extern decls.
5556 Mostly, this hoists extern decls out of .c files and into .h files.
5557 That way, we're more likely to catch errors if the interfaces change.
5558 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5559 declare xg_mark_data.
5560 * dispextern.h (x_frame_parm_handlers):

5580 Remove now-redundant extern decls.
5581 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5582 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5584 * xfaces.c: Remove unnecessary static decls.
5585 * xterm.c (updating_frame): Remove decl of nonexistent object.
5587 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5588 when building globals.h, as the objects that are not built on
5589 this host are not needed to compile C files on this host.
5591 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5593 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5641 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5643 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5644 more than one grapheme cluster passed to the shaper: compute the
5645 offset adjustment values separately for each cluster. (Bug#11860)
5647 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5648 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5649 about implicit conversions from integer to pointer.
5651 2012-09-01 Daniel Colascione <dancol@dancol.org>
5653 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5654 system used too early.

5707 window system declarations.
5709 * frame.h: Move common functions here: set_frame_menubar,
5710 x_set_window_size, x_sync, x_get_focus_frame,
5711 x_set_mouse_position, x_set_mouse_pixel_position,
5712 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5739 * lisp.h (mark_ttys): Remove prototype.
5740 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

5798 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5799 Add window_closed and button_values. Add void as return value for
5800 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5801 Add process_dialog as new member.

5935 (code_convert_string, code_convert_string_norecord)
5936 (Fset_coding_system_priority):
5937 * fileio.c (Finsert_file_contents):
5938 Use bool for booleans.
5939 * coding.h, lisp.h: Reflect above API changes.
5940 * coding.c: Remove unnecessary static function decls.
5941 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5942 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5943 not a boolean 'int', since callers never look at the return value.
5944 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5945 * coding.h (decoding_buffer_size, encoding_buffer_size)
5946 (emacs_mule_string_char): Remove unused extern decls.
5947 (struct iso_2022_spec, struct coding_system):
5948 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5949 (struct emacs_mule_spec): Remove unused field 'full_support'.
5950 All initializations removed.
5951 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5953 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5955 Fix spare memory change (Bug#12286).
5956 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5957 (valid_lisp_object_p): Likewise.
5959 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5961 * window.c (Fset_window_configuration): Record any window's old
5962 buffer if it's replaced (see Bug#8789). If the new current
5963 buffer doesn't appear in the selected window, go to its old
5966 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5968 Special MEM_TYPE_SPARE to denote reserved memory.
5969 * alloc.c (enum mem_type): New memory type.
5970 (refill_memory_reserve): Use new type for spare memory.
5971 This prevents live_cons_p and live_string_p from incorrect
5972 detection of uninitialized objects from spare memory as live.
5974 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5977 * Makefile.in (.PHONY): versioclean -> versionclean.
5979 Remove unused external symbols.
5980 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5981 * window.c (Qwindow_valid_p, decode_valid_window):
5982 Now static, not extern.
5983 * data.c (Qinterval): Remove; unused.
5984 (syms_of_data): Do not define 'interval'.
5985 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5986 * window.h (decode_valid_window):
5989 * character.c, charset.c, chartab.c: Use bool for booleans.
5990 * character.c (lisp_string_width, string_count_byte8)
5991 (string_escape_byte8):
5992 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5993 (load_charset_map_from_file, map_charset_chars)
5994 (Fdefine_charset_internal, define_charset_internal)
5995 (Fdeclare_equiv_charset, find_charsets_in_text)
5996 (Ffind_charset_region, char_charset, Fiso_charset):
5997 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5998 (sub_char_table_set, sub_char_table_set_range)
5999 (char_table_set_range, optimize_sub_char_table)
6000 (map_sub_char_table):
6001 Use bool for boolean.
6002 * character.c (str_to_unibyte): Omit last boolean argument; it was
6003 always 0. All callers changed.
6004 * character.h, charset.h: Adjust to match previous changes.
6005 * character.h (char_printable_p): Remove decl of nonexistent function.
6006 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6007 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6008 are all boolean, so make them single-bit bitfields.
6010 * lisp.h (ASET): Remove attempt to detect side effects.
6011 It was meant to be temporary and it often doesn't work,
6012 because when IDX has side effects the behavior of IDX==IDX
6013 is undefined. See Stefan Monnier in
6014 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6016 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6018 * lisp.h (functionp): New function (extracted from Ffunctionp).
6019 (FUNCTIONP): Use it.
6020 * eval.c (Ffunctionp): Use it.
6022 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6024 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6025 as that's faster and simpler than static storage. Don't bother
6026 with the g_main_context_query overhead if g_main_context_pending
6027 says no events are pending.
6028 (gfds, gfds_size): Remove these static vars.
6029 (xgselect_initialize): Remove; no longer needed.
6030 All uses and decls removed.
6032 * emacs.c (fatal_error_signal_hook): Remove.
6033 All uses removed. This leftover from old code was always 0.
6035 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6036 * casefiddle.c (casify_object, casify_region):
6037 * casetab.c (set_case_table):
6038 * category.c, category.h (word_boundary_p):
6039 * category.h (CHAR_HAS_CATEGORY):
6040 Use bool for booleans, instead of int.
6042 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6044 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6046 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6048 On assertion failure, print backtrace if available.
6049 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6050 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6051 * Makefile.in (LIB_EXECINFO): New macro.
6054 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6055 * bytecode.c (exec_byte_code):
6056 * callint.c (check_mark, Fcall_interactively):
6057 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6058 (getenv_internal, sync_process_alive, call_process_exited):
6059 * lisp.h (USE_SAFE_ALLOCA):
6060 Use bool for booleans, instead of int.
6061 * lisp.h, process.h: Adjust prototypes to match above changes.
6062 * callint.c (Fcall_interactively): Don't assume the mark's
6063 offset fits in 'int'.
6065 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6067 * buffer.c, buffer.h: Use bool for boolean.
6068 * buffer.c (reset_buffer_local_variables)
6069 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6070 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6071 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6072 (overlay_touches_p, overlay_strings, Foverlay_put)
6073 (report_overlay_modification, call_overlay_mod_hooks):
6074 (mmap_enlarge, mmap_set_vars):
6075 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6076 Use bool for booleans, instead of int.
6077 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6078 since the 1-or-0 return value is always ignored anyway.
6079 (mmap_initialized_p):
6080 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6081 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6083 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6085 * bidi.c: Use bool for boolean.
6086 This is a bit more readable, and makes the text segment of bidi.o
6087 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6088 Presumably it's faster too.
6089 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6091 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6092 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6093 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6094 (bidi_explicit_dir_char, bidi_level_of_next_char)
6095 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6096 Use bool for booleans, instead of int.
6097 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6098 (bidi_unshelve_cache): Adjust decls to match code.
6100 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6102 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6105 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6107 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6108 * atimer.h: Include <stdbool.h>.
6110 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6112 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6113 compile time tests instead of run time tests on systems that do
6115 (FRAME_MAC_P): Remove leftover from deleted code.
6116 * frame.c (syms_of_frame): Remove leftover from deleted code.
6118 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6120 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6122 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6124 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6125 Otherwise, the compiler complains about (A?B:C) where B is void
6126 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6127 (fontset_add): Return void, for FONTSET_ADD.
6129 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6131 * alloc.c: Use bool for booleans.
6132 (gc_in_progress, abort_on_gc)
6133 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6134 (dont_register_blocks) [GC_MALLOC_CHECK]:
6135 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6136 (check_string_bytes, make_specified_string, memory_full)
6137 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6138 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6139 (mark_stack, valid_pointer_p, make_pure_string)
6140 (Fgarbage_collect, survives_gc_p, gc_sweep):
6141 Use bool for booleans, instead of int.
6142 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6143 Remove unused local.
6144 * alloc.c (PURE_POINTER_P):
6145 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6146 * editfns.c (Fformat):
6147 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6149 * fns.c (sweep_weak_table):
6150 * lisp.h (suppress_checking, push_message, survives_gc_p)
6151 (make_pure_string, gc_in_progress, abort_on_gc):
6152 * lread.c (readchar, read1):
6153 * print.c (Fprin1_to_string):
6154 * xdisp.c (push_message):
6155 Use bool for booleans affected directly or indirectly by
6158 Make recently-introduced setters macros.
6159 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6160 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6161 (set_fontset_default, set_fontset_fallback): Rename from their
6162 upper-case counterparts, and make them functions rather than macros.
6163 This is more consistent with the other recently-introduced setters.
6164 These don't need to be inline, since they're local.
6166 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6168 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6169 the loop (Bug#12247).
6171 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6173 * lisp.h (vcopy): Use memcpy rather than our own loop.
6174 This fixes a performance regression introduced by the recent
6175 addition of vcopy. This means 'vcopy' will need to be modified
6176 for a copying collector, but that's OK. Also, tighten the
6177 checking in the assertion.
6179 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6181 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6182 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6183 non-base glyph for the width of the base character, according to
6184 what x_draw_composite_glyph_string_foreground expects.
6185 Generate WADJUST value according to composition_gstring_width's
6186 expectations, to produce correct width of the composed character.
6187 Reverse the sign of the DU offset produced by ScriptPlace.
6189 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6191 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6193 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6195 Avoid direct writes to contents member of struct Lisp_Vector.
6196 * lisp.h (vcopy): New function to copy data into vector.
6197 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6198 * fns.c (Ffillarray): Use ASET.
6199 * keyboard.c (timer_check_2): Use AREF and ASET.
6200 (append_tool_bar_item, Frecent_keys): Use vcopy.
6201 * lread.c (read_vector): Use ASET.
6202 * msdos.c (Frecent_doskeys): Use vcopy.
6203 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6204 (Finternal_merge_in_global_face): Use ASET and vcopy.
6205 * xfont.c (xfont_list_pattern): Likewise.
6207 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6209 * window.c (Fwindow_point): For the selected window always return
6210 the position of its buffer's point.
6211 (Fset_window_point): For the selected window always go in its
6212 buffer to the specified position.
6214 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6216 Setter macros for fontsets.
6217 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6218 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6219 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6222 2012-08-20 Glenn Morris <rgm@gnu.org>
6224 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6225 Don't assume that `ln -f' works.
6227 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6229 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6230 and later about non-assignments with no effect. See discussion at
6231 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6234 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6236 Inline setter functions for Lisp_Objects slots of struct specbinding.
6237 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6240 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6242 * window.c (select_window): Always make selected window's buffer
6245 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6247 Use AREF and ASET for docstrings of category tables.
6248 * category.h (CATEGORY_DOCSTRING): Use AREF.
6249 (SET_CATEGORY_DOCSTRING): Use ASET.
6250 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6252 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6254 Inline setter functions for hash table members.
6255 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6256 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6257 (set_hash_key_and_value, set_hash_index, set_hash_next)
6258 (set_hash_hash): New functions.
6259 * charset.c, fns.c: Adjust users.
6261 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6263 Inline getter and setter functions for per-buffer values.
6264 * buffer.h (per_buffer_default, set_per_buffer_default)
6265 (per_buffer_value, set_per_buffer_value): New functions.
6266 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6267 * buffer.c, data.c: Adjust users.
6269 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6271 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6273 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6275 Rely on <config.h> + <unistd.h> to declare 'environ',
6276 as gnulib does this if the system doesn't.
6277 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6278 Remove declaration. MS-Windows declares it on stdlib.h which is
6279 included by conf_post.h.
6280 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6281 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6282 * vm-limit.c: Include <unistd.h>, for 'environ'.
6284 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6285 (start_of_data): Remove decl; mem-limits.h provides it.
6287 * xdisp.c (handle_invisible_prop): Make it a bit faster
6288 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6290 2012-08-19 Chong Yidong <cyd@gnu.org>
6292 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6295 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6297 * .gdbinit: Use call instead of set when calling a function in the
6300 * data.c (set_internal): Don't use set_blv_found.
6301 (Fkill_local_variable): Likewise.
6303 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6305 * nsfont.m (ns_ascii_average_width): Ensure the string
6306 ascii_printable is initialized with a null-terminated character
6307 array. Otherwise, it can contain undesired extra characters.
6309 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6311 port new setting code to Sun C 5.8 2005/10/13
6312 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6313 Return void, not Lisp_Object. Otherwise, the compiler
6314 complains about (A?B:C) where B is void and C is Lisp_Object
6315 when compiling CHAR_TABLE_SET, due to the recent change to
6316 the API of sub_char_table_set_contents.
6318 2012-08-18 Chong Yidong <cyd@gnu.org>
6320 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6321 for the string case (Bug#3874).
6323 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6325 * buffer.h (BSET): Remove (Bug#12215).
6326 Replace all uses with calls to new setter functions.

6353 (bset_word_wrap, bset_zv_marker):
6354 * category.c (bset_category_table):
6355 * syntax.c (bset_syntax_table):
6356 New setter functions.
6358 * process.h (PSET): Remove (Bug#12215).
6359 Replace all uses with calls to new setter functions.
6360 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.

7258 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7259 checking subscripts; problem introduced with the recent
7260 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7261 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7262 since it's used in non-static inline functions now.
7264 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7265 Don't assume buffer size fits in 'int'. Remove unused local.

7291 (INLINE_HEADER_END): New macros.
7292 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7317 This how ASET and AREF are supposed to work, and makes
7318 it easier to think about future improvements. See
7319 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7320 * charset.h (set_charset_attr): New function.

7701 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7702 (w32_kbd_patch_key, key_event): Use the codepage returned by
7703 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7704 (key_event): use uChar.UnicodeChar only if
7705 w32_console_unicode_input is non-zero.
7707 * w32console.c: Include w32heap.h.

7735 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7736 enumeration constants, as PURE and HEAP are too general, and clash
7737 with other headers and sources, such as gmalloc.c and the
7738 MS-Windows system headers. All users changed.
7740 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7742 Revert last save_excursion_save and save_excursion_restore changes.
7743 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7753 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7755 Improve GDB symbol export (Bug#12036).
7756 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7757 arms of an 'if', not using conditional expressions; otherwise GDB
7758 complains about the types in the unevaluated arm when the argument
7759 is an integer literal.
7760 (xgetint): Simplify expression.
7761 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7762 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7763 Zaretskii in <http://bugs.gnu.org/12036#13>.
7764 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7765 needed now that we have gdb_make_enums_visible.
7766 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7767 (enum enum_USE_LSB_TAG):
7768 New enum types, packaging up enums that need to be exported to GDB.

7787 * xfns.c (syms_of_xfns): Likewise.
7789 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7791 Fast save_excursion_save and save_excursion_restore.
7792 * lisp.h (struct Lisp_Excursion): New data type.
7793 (PVEC_EXCURSION): New pseudovector type.
7794 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7795 to deal with it. Adjust comments.

7809 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
7810 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7811 emacs.c, as this is a more-suitable home. Had this been done earlier
7812 the fix for 12036 would have avoided some of the problems noted in
7813 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7814 would have been more obvious.
7815 * emacs.c: Do not include <verify.h>; no longer needed.
7816 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7817 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7818 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7819 Remove; now done in lisp.h.
7820 * lisp.h (PUBLISH_TO_GDB): New macro.
7821 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
7822 (DATA_SEG_BITS): Use it.
7823 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7824 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7825 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7826 not be usable in #if. This simplifies things.
7828 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7830 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7832 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7834 Simplify export of symbols to GDB (Bug#12036).
7835 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7836 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7837 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7838 Adjust to changes in lisp.h and emacs.c, by using
7839 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7840 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7841 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7842 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7843 instead of gdb_valbits.
7844 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7845 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7846 instead of gdb_array_mark_flag.
7847 (xboolvector): Get size from $->size, not $->header.size.
7848 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7849 (xreload, hook-run, hookpost-run): Remove.
7850 * emacs.c: Include <verify.h>.
7851 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7852 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7854 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7855 (gdb_USE_LSB_TAG): New enum constants.
7856 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7857 Also define these as enum constants, so they're visible to GDB.
7858 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7859 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7860 as constants, so they're visible to GDB.
7861 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7862 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7863 Now enum constants, not macros, so they're visible to GDB.
7864 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7865 more convenient now. All uses changed.
7866 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7867 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7869 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7876 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7877 add argument, tune behavior, and adjust all callers.
7879 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7881 Use typedef for EMACS_INT, EMACS_UINT.
7882 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7883 than macros. This simplifies debugging in the usual case, since
7884 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7885 and it allows expressions involving EMACS_INT casts.
7886 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7888 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7896 that FOCUS-FRAME can be omitted.
7898 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7900 Adjust buffer text indirection counters at the end of Fkill_buffer.
7901 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7902 buffer is definitely dead. This should really fix an issue reported
7903 by Christoph Scholtes again. (Bug#12007).
7904 (init_buffer_once): Initialize indirection counters of
7905 buffer_defaults and buffer_local_symbols (for sanity and safety).
7907 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7909 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7910 and continuation glyphs on tooltip frames, leave them at zero.

7913 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7915 Simplify copy_overlay.
7916 * buffer.c (copy_overlay): Simplify. Use build_marker.

7936 (build_overlay): Add prototype.
7938 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7940 Swap buffer text indirection counters in Fbuffer_swap_text.
7941 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7942 This avoids crash reported by Christoph Scholtes at
7943 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7945 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7947 * nsmenu.m (Popdown_data): New struct.
7948 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7950 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7951 (initWithContentRect): Make imgView and contentView non-static
7952 and autorelease them. Also autorelease img and matrix (Bug#12005).
7953 (dealloc): Remove (Bug#12005).
7955 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7957 Adjust consing_since_gc when objects are explicitly freed.
7958 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
7959 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

7966 (live_buffer, set_marker_internal): New function.
7967 (Fset_marker, set_marker_restricted): Use set_marker_internal.

7970 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7972 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7973 as it's limited by the amount of memory, not by INT_MAX.
7975 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7977 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7978 in special-event-map. See the discussion at

8037 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8038 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8039 Adjust users accordingly.
8040 * font.h (font_open_by_name): Adjust prototype.

8058 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8059 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8060 'for_each_per_buffer_object_at'.
8061 All uses changed. It's better to use upper-case for macros that
8062 cannot be implemented as functions, to give the reader a clue
8063 that they're special.
8065 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8067 * alloc.c (Fgarbage_collect): Tweak docstring.

8108 * intervals.c (merge_interval_right, merge_interval_left):
8109 Do not zero out this interval if it is absorbed by its children,

8113 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8115 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8116 when invoking (make-bool-vector N t) and N is a positive

8119 Remove some struct layout assumptions in bool vectors.
8120 * alloc.c (bool_header_size): New constant.
8121 (header_size, word_size): Move earlier, as they're now used earlier.

8586 2012-07-11 Glenn Morris <rgm@gnu.org>
8588 * s/gnu-linux.h, s/sol2-6.h: No longer define POSIX,
8589 unused since 2011-01-17 change to systty.h.

8631 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8632 since nothing has defined it on these platforms.

8646 2012-07-11 John Wiegley <johnw@newartisans.com>
8648 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8649 function attribute, so we only use it if it exists in the
8652 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8654 Avoid call to strlen in fast_c_string_match_ignore_case.

8701 * s/aix4-2.h (unix): Remove; no longer needed.
8703 EMACS_TIME simplification (Bug#11875).
8704 This replaces macros (which typically do not work in GDB)
8705 with functions, typedefs and enums, making the code easier to debug.
8706 The functional style also makes code easier to read and maintain.
8707 * systime.h: Include <sys/time.h> on all hosts, not just if
8708 WINDOWSNT, since 'struct timeval' is needed in general.
8709 (EMACS_TIME): Now a typedef, not a macro.
8710 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8712 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8716 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8717 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8718 which are not functions. All uses rewritten to use:
8719 (make_emacs_time): New function.
8720 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8721 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8722 not functions. All uses rewritten to use the following, respectively:
8723 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8724 (add_emacs_time, sub_emacs_time): New functions.
8725 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8726 * fileio.c (Fcopy_file):
8727 * xterm.c (XTflash): Get the current time closer to when it's used.
8728 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8742 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8743 (menu_separator_name_p):
8744 * nsmenu.m (ns_update_menubar):
8745 Prefer memcmp to strncmp when either will do.
8746 * nsterm.m: Include <ftoastr.h>.
8748 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8749 Prefer snprintf to strncpy.
8750 * nsterm.m (ns_term_init):
8751 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8752 * nsterm.m (ns_term_init):
8753 Avoid the need for strncpy, by using build_string or
8754 make_unibyte_string directly. Use dtoastr, not snprintf.
8755 * process.c (Fmake_network_process): Diagnose service names that
8756 are too long, rather than silently truncating them or creating
8757 non-null-terminated names.
8758 (Fnetwork_interface_info): Likewise, for interface names.
8759 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8760 Prefer sprintf to strncat.
8761 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8762 Prefer vsnprintf to vsprintf + strncpy.
8764 2012-07-10 Glenn Morris <rgm@gnu.org>
8766 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8767 Clarify fallback case.
8769 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8771 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8772 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8773 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8774 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8775 where argument type is known to be a Lisp_Cons.
8777 2012-07-10 Tom Tromey <tromey@redhat.com>
8779 * bytecode.c (BYTE_CODE_THREADED): New macro.

8787 Optimize pure C strings initialization.
8788 * lisp.h (make_pure_string): Fix prototype.
8789 (build_pure_c_string): New function, defined as static inline. This
8790 provides a better opportunity to optimize away calls to strlen when
8791 the function is called with compile-time constant argument.
8792 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8793 argument, adjust users accordingly. Use build_pure_c_string where
8795 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8796 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8797 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8799 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8801 Avoid calls to strlen in miscellaneous functions.
8802 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8803 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8804 * lread.c (openp): Likewise.
8806 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8808 Avoid calls to strlen in path processing functions.
8809 * fileio.c (file_name_as_directory): Add comment. Change to add
8810 srclen argument and return the length of result. Adjust users
8812 (directory_file_name): Fix comment. Change to add srclen argument,
8813 swap 1st and 2nd arguments to obey the common convention.
8814 Adjust users accordingly.
8815 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8817 2012-07-10 Glenn Morris <rgm@gnu.org>
8819 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8822 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8823 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8824 * s/gnu.h (DATA_START): Move definitions to configure.
8826 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8827 We include usg5-4-common.h, which defines them both.
8829 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8830 O_RDONLY already includes it).
8832 Stop ns builds setting the EMACSLOADPATH environment variable.
8833 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8834 Now it does not set EMACSLOADPATH, just returns the load-path string.
8835 * nsterm.h: Update accordingly.
8836 * lread.c [HAVE_NS]: Include nsterm.h.
8837 (init_lread) [HAVE_NS]: Use ns_load_path.
8838 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8840 2012-07-09 Glenn Morris <rgm@gnu.org>
8842 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8843 since the included bsd-common.h does so.
8845 Stop ns builds setting the EMACSPATH environment variable.
8846 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8847 (ns_init_paths): Do not set EMACSPATH.
8848 * nsterm.h (ns_exec_path): Add it.
8849 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8852 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8854 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8856 * process.c (wait_reading_process_output): 'waitchannels' was unset
8857 when read_kbd || !NILP (wait_for_cell); fix this.
8859 Add GCC-style 'const' attribute to functions that can use it.
8860 * character.h (char_resolve_modifier_mask):
8861 * keyboard.h (make_ctrl_char):
8862 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8863 (init_character_once, next_almost_prime, init_fns, init_image)
8864 (flush_pending_output, init_sound):
8865 * mem-limits.h (start_of_data):
8866 * menu.h (finish_menu_items):

8869 Declare the dummy function with ATTRIBUTE_CONST.
8870 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8871 Add decls with ATTRIBUTE_CONST.
8873 Minor improvements to make_formatted_string.
8874 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8875 where int is good enough, as vsprintf returns an int.
8876 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8878 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8880 Use make_formatted_string to avoid double length calculation.
8881 * lisp.h (make_formatted_string): New prototype.
8882 * alloc.c (make_formatted_string): New function.
8883 * buffer.c (Fgenerate_new_buffer_name): Use it.
8884 * dbusbind.c (syms_of_dbusbind): Likewise.
8885 * editfns.c (Fcurrent_time_zone): Likewise.
8886 * filelock.c (get_boot_time): Likewise.
8887 * frame.c (make_terminal_frame, set_term_frame_name)
8888 (x_report_frame_params): Likewise.
8889 * image.c (gs_load): Likewise.
8890 * minibuf.c (get_minibuffer): Likewise.

8905 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8907 Move marker debugging code under MARKER_DEBUG.
8908 * marker.c (MARKER_DEBUG): Move marker debugging code under
8909 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8910 for bootstrap with --enable-checking (~3x slowdown reported
8911 by Juanma Barranquero <lekktu@gmail.com>).
8912 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8914 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8916 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8917 See <http://bugs.gnu.org/11825#29>.
8919 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8921 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8922 has no font, use the frame's font. (Bug#11813)
8923 (display_line): Add commentary about displaying truncation glyphs
8925 (produce_special_glyphs): Move here from term.c.
8927 * term.c (produce_special_glyphs): Move to xdisp.c.
8929 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8932 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8934 * xdisp.c (display_line): Avoid warning about implicit declaration
8937 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8939 * lisp.h: Remove empty conditional.
8941 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8943 * lread.c (load_path_check): Now static.
8945 Fix some minor --with-ns problems found by static checking.
8946 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8947 (x_set_font) [!HAVE_X_WINDOWS]:
8948 * image.c (xpm_load_image) [HAVE_NS]:
8949 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8950 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8951 Remove unused local.
8952 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8953 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8954 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8955 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8956 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8957 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8958 Fix pointer signedness problem.
8959 * xfaces.c (FRAME_X_FONT_TABLE):
8960 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8962 2012-07-07 Glenn Morris <rgm@gnu.org>
8964 * lread.c (load_path_check): New function, split from init_lread.
8965 (init_lread): Reorganize. Motivation:
8966 If EMACSLOADPATH is set, check/warn about that rather than the
8967 defaults, which we are not going to use. Hence we can remove
8968 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8969 Don't warn if site-lisp directories are missing.
8970 If not installed, start from a blank load-path, since
8971 PATH_LOADSEARCH refers to the eventual installation directories.
8973 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8975 Support truncation and continuation glyphs on GUI frames, when
8976 fringes are disabled. (Bug#11832)
8977 * xdisp.c (init_iterator): Get dimensions of truncation and
8978 continuation glyphs even if on GUI frames.
8979 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8980 or both, are absent.
8981 (start_display, move_it_in_display_line_to): Handle the case of a
8982 GUI frame without a fringe to display continuation or truncation
8984 (insert_left_trunc_glyphs): Support GUI frames: make sure
8985 truncation glyphs overwrite enough glyphs from the current line to
8986 have sufficient space in pixels.
8987 (display_line): Support truncation and continuation glyphs on GUI
8988 frames. If some spare pixels are left on the line after inserting
8989 the truncation glyphs, fill that space with a stretch glyph of a
8990 suitably computed width.
8992 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8993 produce_glyphs, to support GUI sessions.
8995 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8997 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8999 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9001 Do not require float-time's arg to fit in time_t (Bug#11825).
9002 This works better on hosts where time_t is unsigned, and where
9003 float-time is applied to the (negative) difference between two times.
9004 * editfns.c (decode_time_components): Last arg is now double *,
9005 not int *, and means to store all the result as a double, without
9006 worrying about whether the seconds part fits in time_t.
9007 All callers changed.
9008 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9009 All callers changed.
9010 (Ffloat_time): Do not fail merely because the specified time falls
9011 outside of time_t range.
9013 2012-07-07 Glenn Morris <rgm@gnu.org>
9015 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9016 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9017 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).

9040 * w32fns.c (Fx_change_window_property): Doc fix.
9042 * w32fns.c (Fx_window_property): Accept the same arguments as the
9043 X Windows version. Doc fix.
9044 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9046 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9047 Eli Zaretskii <eliz@gnu.org>
9049 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

9051 Obsolete settings removed.
9053 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9055 * process.c: Avoid unnecessary calls to gettime.
9056 (wait_reading_process_output): Don't get the time of day
9057 when gobbling data immediately and not waiting, as there's no need
9058 for it in that case. This removes a FIXME.
9060 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9062 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9063 is defined (Bug#11768).

9067 Fix marker debugging code.
9068 * marker.c (byte_char_debug_check): Do not perform the check
9069 if buffer is not multibyte.
9070 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):

9073 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9075 Compile marker debugging code only if ENABLE_CHECKING is defined.
9076 * marker.c (byte_char_debug_check, count_markers):
9077 Use only if ENABLE_CHECKING is defined.
9078 (byte_debug_flag): Remove.
9079 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9080 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9082 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9084 Avoid code repetition in marker-related functions.
9085 * marker.c (attach_marker): New function.

9088 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9089 Consistently rename charno to charpos.
9090 (marker_position): Add eassert.
9091 (marker_byte_position): Convert to eassert.

9103 * lisp.h (build_marker): New prototype.
9104 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9105 * composite.c (autocmp_chars): Likewise.
9106 * editfns.c (buildmark): Remove.
9107 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9108 (save_restriction_save): Use build_marker.
9109 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9110 * window.c (save_window_save): Likewise.
9112 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9118 * minibuf.c (get_minibuffer): Fix comment.
9120 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9122 Port to OpenBSD 5.1 amd64.
9123 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9124 This is needed for OpenBSD, and should be harmless on all BSD systems.
9125 Also, include <sys/sysctl.h>, as it should be available on all
9126 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9127 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9128 use p_pid member, not kp_proc.pid.
9130 2012-07-06 Glenn Morris <rgm@gnu.org>
9132 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9134 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9136 More xmalloc and related cleanup.

9145 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9147 Omit needless casts involving void * pointers and allocation.
9148 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9149 as the former is more robust if P's type is changed.
9150 Prefer xzalloc to xmalloc + memset 0.
9151 Simplify malloc-or-realloc to realloc.
9152 Don't worry about xmalloc returning a null pointer.
9153 Prefer xstrdup to xmalloc + strcpy.
9154 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9156 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9157 alloca of a constant.
9159 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9161 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9162 hscroll is larger than the line width. Fixes long and futile
9163 looping inside extend_face_to_end_of_line (on a TTY) producing
9164 glyphs that are not needed and thrown away.
9166 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9168 * marker.c (set_marker_restricted_both): Simplify by using
9171 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9173 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9175 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

9180 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9181 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9182 followed by gtk_box_set_homogeneous (Bug#11768).
9183 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9184 (update_theme_scrollbar_width, xg_create_scroll_bar):
9185 Use gtk_scrollbar_new (Bug#11768).
9186 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9187 (is_box_type): New function (Bug#11768).
9188 (xg_tool_item_stale_p): Call is_box_type.
9189 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9190 with default display (Bug#11768).

9194 * xdisp.c (window_hscroll_limited): New function.
9195 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9196 coordinates when window's hscroll is set to insanely large
9199 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

9260 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9262 * fileio.c (time_error_value): Check the right error number.
9263 Problem reported by Troels Nielsen in
9264 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

9268 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9269 This should be fixed in a better way; see Eli Zaretskii in
9270 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9271 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9273 * fileio.c (time_error_value): Rename from special_mtime.
9274 The old name's problems were noted by Eli Zaretskii in
9275 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9277 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9278 This variable's comment says Emacs needs at least one GDB-visible
9279 symbol of type enum pvec_type, to work around GDB problems.
9280 The symbol's value doesn't matter.
9282 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9283 that causes compilation to fail on pre-C99 compilers.
9285 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9287 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9288 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9290 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9292 * buffer.c (init_buffer_once): Fix initialization of
9293 headers for buffer_defaults and buffer_local_symbols.
9294 Reported by Juanma Barranquero <lekktu@gmail.com>.

9298 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9299 * lisp.h (enum pvec_type): Use fewer bits.
9300 (PSEUDOVECTOR_SIZE_BITS): New constant.
9301 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9302 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9303 change in pvec_type.
9304 (PSEUDOVECTOR_TYPEP): New macro.

9310 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9311 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9312 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9313 abusing vector->header.next.nbytes.
9314 (live_vector_p): Use PVEC_TYPE.
9315 (mark_object): Adapt code to extract pvectype. Use switch.
9317 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9319 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9320 Tighten new eassert a bit.
9322 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9324 Fix compilation with --enable-gcc-warnings and -O1
9326 * doprnt.c (doprnt): Change type of tem to int, initialize
9327 to avoid compiler warning. Add eassert.
9328 * search.c (simple_search): Initialize match_byte to avoid
9329 compiler warning. Add eassert.
9331 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9333 Avoid weird behavior with large horizontal scrolls.
9334 Without this change, for example, large hscroll values would
9335 mess up Emacs's display on Fedora 15 x86, presumably due to
9336 overflows in int calculations in the display code.
9337 Also, if buffers had long lines, Emacs would freeze.
9338 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9339 (set_window_hscroll): New function, containing the old guts of
9340 Fset_window_hscroll. Return the clipped value.
9341 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9342 This avoids the need to check against PTRDIFF_MAX.
9344 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9346 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9350 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9352 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9353 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9354 since GCC 4.4.6 issues a bogus warning for them.
9356 Fix bugs in file timestamp newness comparisons.
9357 * fileio.c (Ffile_newer_than_file_p):
9358 * lread.c (Fload): Use full timestamp resolution of files,
9359 not just the 1-second resolution, so that files that are only
9360 slightly newer still count as newer.
9361 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9362 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9364 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9366 * fileio.c: Improve handling of file time marker. (Bug#11852)
9367 (special_mtime): New function.
9368 (Finsert_file_contents, Fverify_visited_file_modtime):
9369 Use it to set special mtime values consistently.
9371 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9373 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9374 marker for non-existing file. (Bug#11852)
9376 2012-07-03 Glenn Morris <rgm@gnu.org>
9378 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9379 and did not make it into globals.h).
9381 2012-07-03 Tom Tromey <tromey@redhat.com>

9419 2012-07-03 Glenn Morris <rgm@gnu.org>
9421 * lisp.h (Frandom): Make it visible to C.
9422 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9423 buffer for invisible buffers. (Bug#1229)

9427 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9428 values which aren't power of 2.
9429 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9430 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9433 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9435 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

9441 * alloc.c (allocate_vector_block): Remove redundant
9442 calls to mallopt if DOUG_LEA_MALLOC is defined.
9443 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9444 avoid calls to mallopt if zero_vector is returned.
9446 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9448 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9449 is enabled, avoid dereferencing NULL current_sblock if
9452 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9454 Cleanup basic buffer management.
9455 * buffer.h (struct buffer): Change layout to use generic vector
9456 marking code. Fix some comments. Change type of 'clip_changed'
9457 to bitfield. Remove unused #ifndef old.
9458 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

9468 Lisp area of struct buffer.
9469 (mark_object): Use it. Adjust marking of misc objects
9470 and related comments.
9472 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9474 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9475 wrapper that is not needed because the wrapped code is a no-op (zero
9476 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9477 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9479 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9481 * alloc.c (mark_buffer): Simplify. Remove prototype.
9482 (mark_object): Add comment. Reorganize marking of vector-like
9483 objects. Use CHECK_LIVE for all vector-like objects except buffers
9484 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9485 Avoid redundant calls to mark_vectorlike for bool vectors.
9487 2012-06-30 Glenn Morris <rgm@gnu.org>
9489 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9491 * epaths.in (PATH_SITELOADSEARCH): New.
9492 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9493 This is rather than relying on --enable-locallisppath elements
9494 having "site-lisp" in their names. (Bug#10208#25, 11658)
9496 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9498 * w32proc.c (sys_select): Accept and ignore one more argument.
9500 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9502 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9503 (pselect) [!MS_DOS]: Redirect to sys_select.
9505 * sysdep.c: Don't include dos.h and dosfns.h.
9507 * process.c (sys_select):
9508 * msdos.c (sys_select): Accept one more argument and ignore it.
9510 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9511 adapt data types and code to that.
9514 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9515 which clashes with the gnulib function of the same name.
9517 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9519 * font.c (font_style_to_value, font_style_symbolic)
9520 (font_prop_validate_style): Add type checks for values in
9523 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9525 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9528 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9530 * xdisp.c (try_window_id): Undo last change.
9532 * w32.c (getwd): Adjust commentary about startup_dir.
9533 (init_environment): Always call sys_access, even in non-MSVC
9534 builds. Don't chdir to the directory of the Emacs executable.
9535 This undoes code from 1997 which was justified by the need to
9536 "avoid conflicts when removing and renaming directories". But its
9537 downside was that every relative file name was being interpreted
9538 relative to the directory of the Emacs executable, which can never
9539 be TRT. In particular, it broke sys_access when called with
9540 relative file names.
9541 (sys_access): Map GetLastError to errno.
9543 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9545 * window.h (struct window): Change type of 'fringes_outside_margins'

9555 Add QUIT to make the loop interruptible.
9557 2012-06-29 Glenn Morris <rgm@gnu.org>

9580 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9581 overflow when requested scroll falls outside ptrdiff_t range.

9585 * window.h (struct window): Change type of 'hscroll',
9586 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9587 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9588 Adjust users accordingly.
9589 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9590 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9591 from EMACS_INT to ptrdiff_t.
9592 (make_window): Omit redundant initialization.
9594 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9598 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

9667 * alloc.c (allocate_string): Omit intervals initialization.
9668 * alloc.c (make_uninit_multibyte_string): Initialize intervals

9725 * alloc.c: Remove build_string.
9726 * lisp.h: Define build_string as static inline. This provides
9727 a better opportunity to optimize away calls to strlen when the
9728 function is called with compile-time constant argument.
9729 * image.c (imagemagick_error): Convert to build_string.
9730 * w32proc.c (sys_spawnve): Likewise.

9733 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9735 Use sprintf return value instead of invoking strlen on result.
9736 In the old days this wasn't portable, since some sprintf
9737 implementations returned char *. But they died out years ago and
9738 Emacs already assumes sprintf returns int.
9739 Similarly for float_to_string.
9740 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9745 * print.c (print_object):
9746 * xdisp.c (message_dolog):
9747 * xfns.c (syms_of_xfns):
9748 Use sprintf or float_to_string result to avoid need to call strlen.
9749 * data.c (Fnumber_to_string):
9750 Use make_unibyte_string, since the string must be ASCII.
9751 * lisp.h, print.c (float_to_string): Now returns int length.
9752 * term.c (produce_glyphless_glyph):
9753 Use sprintf result rather than recomputing it.
9755 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9756 * Makefile.in (ALL_CFLAGS):
9757 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

9763 strcasecmp if available.

9782 sprintf already null-terminates its output.
9784 * xfns.c (x_window): Remove redundant cast.
9786 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9788 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9789 `const char *' to `char *' to avoid compiler warning.
9791 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9793 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9794 instead of truncating it to 63 (admittedly a generous limit).
9796 * process.c: Fix spelling and caps in comments.
9798 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

9854 * keyboard.c (kbd_buffer_get_event):
9855 * process.c (Faccept_process_output):
9856 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9857 This improves on the previous patch, which introduced a bug
9858 when time_t is unsigned and as wide as intmax_t.
9859 See <http://bugs.gnu.org/9000#51>.
9861 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9877 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9878 Privately reported by Herbert J. Skuhra.
9879 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9881 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9882 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9884 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9924 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9926 Support higher-resolution time stamps (Bug#9000).
9927 The time stamps are only nanosecond-resolution at the C level,
9928 since that's the best that any real-world system supports now.
9929 But they are picosecond-resolution at the Lisp level, as that's
9930 easy, and leaves room for future OS improvements.
9932 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9935 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9936 Don't get current time unless it's needed.
9938 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9939 now provides it if it's absent.
9940 (start_atimer): Port to higher-res time stamps.
9941 Check for time stamp overflow. Don't get current time more
9942 often than is needed.
9944 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9945 Include systime.h, not time.h.
9946 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9948 * dired.c: Include stat-time.h.
9949 (Ffile-attributes): File times now have higher resolution.
9951 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9952 (struct image): Timestamp now has higher resolution.
9954 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9955 has at least microseconds now. All uses removed.
9956 (update_frame, update_single_window, update_window, update_frame_1)
9957 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9958 (duration_to_sec_usec): Remove; no longer needed.
9960 * editfns.c (time_overflow): Now extern.
9961 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9962 (float-time, Fformat_time_string, Fcurrent_time_string)
9963 (Fcurrent_time_zone): Accept and generate higher-resolution
9965 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9966 (decode_time_components, lisp_seconds_argument): New functions.
9967 (make_time): Now static.
9968 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9969 Report an error if the time is invalid, rather than having the caller
9972 * fileio.c: Include <stat-time.h>
9973 (Fcopy_file): Copy higher-resolution time stamps.
9974 Prefer to set the time stamp via a file descriptor if that works.
9975 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9976 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9977 (Fvisited_file_modtime, Fset_visited_file_modtime):
9978 Support higher-resolution time stamps.
9980 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9982 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9984 * image.c (prepare_image_for_display, clear_image_cache)
9985 (lookup_image): Port to higer-resolution time stamps.
9987 * keyboard.c (start_polling, bind_polling_period):
9988 Check for time stamp overflow.
9989 (read_char, kbd_buffer_get_event, timer_start_idle)
9990 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9991 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9992 Port to higher-resolution time stamps. Do not assume time_t is signed.
9993 (decode_timer): New function. Timers are now vectors of length 9,
9994 not 8, to accommodate the picosecond component.
9995 (timer_check_2): Use it.
9997 * nsterm.m (select_timeout, timeval_subtract): Remove.
9998 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9999 as they're a bit more accurate and handle overflow better.
10000 (ns_select): Change prototype to be compatible with pselect.
10001 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10002 * nsterm.h (ns_select): Adjust prototype.
10004 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10005 us-resolution time stamps.
10006 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10008 * lread.c (read_filtered_event): Port to ns-resolution time stamps.

10014 * process.h (struct Lisp_Process.read_output_delay):
10015 Now counts nanoseconds, not microseconds.
10016 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10018 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10019 (wait_reading_process_output):
10020 Port to ns-resolution time stamps.
10021 (Faccept_process_output, wait_reading_process_output):
10022 Check for time stamp overflow. Do not assume time_t is signed.
10023 (select_wrapper): Remove; we now use pselect.
10024 (Fprocess_attributes): Now generates ns-resolution time stamps.
10026 * sysdep.c: Include utimens.h. Don't include utime.h
10027 or worry about struct utimbuf; gnulib does that for us now.
10028 (gettimeofday): Remove; gnulib provides a substitute.
10029 (make_timeval): New function.
10030 (set_file_times): Now sets ns-resolution time stamps.
10031 New arg FD; all uses changed.
10032 (time_from_jiffies, ltime_from_jiffies, get_up_time)

10034 Now returns ns-resolution time stamp. All uses changed.
10035 Check for time stamp overflow.
10037 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10038 provides a substitute now.
10040 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10041 since it guarantees struct timespec.
10042 (EMACS_TIME): Now struct timespec, so that we can support
10043 ns-resolution time stamps.
10044 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10045 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10046 (EMACS_USECS): Remove.
10047 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10048 so multiply the arg by 1000 before storing it.
10049 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10051 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10058 (make_timeval, make_lisp_time, decode_time_components): New decls.
10059 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10060 that it mishandled time_t overflow. You can't compare by subtracting!
10061 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10062 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10064 * term.c: Include <sys/time.h>.
10065 (timeval_to_Time): New function, for proper overflow wraparound.
10066 (term_mouse_position, term_mouse_click): Use it.
10068 * undo.c (record_first_change): Support higher-resolution time stamps
10069 in the undo buffer.
10070 (Fprimitive_undo): Use them when restoring time stamps.
10072 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10073 (w32_get_internal_run_time):
10074 Port to higher-resolution Emacs time stamps.
10075 (ltime): Now accepts single 64-bit integer, as that's more convenient
10078 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10080 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10081 for compatibility with pselect. Support ns-resolution time stamps.
10083 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10085 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10086 Check for time stamp overflow, and support ns-resolution time stamps.
10088 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10089 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10090 (timeval_subtract): Remove; no longer needed.
10091 (XTflash, XTring_bell, x_wait_for_event):
10092 Port to ns-resolution time stamps. Don't assume time_t is signed.
10094 2012-06-22 Chong Yidong <cyd@gnu.org>

10098 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10100 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10101 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10102 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10103 staticidx goes up to 1597 out of 1600 = 0x640.)
10105 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10107 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10108 Otherwise, the umask might be mistakenly 0 while handling input signals.
10110 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10112 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10118 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10119 access to `contents' member of Lisp_Vector objects with AREF and ASET
10122 2012-06-19 Chong Yidong <cyd@gnu.org>
10124 * frame.c (delete_frame): When selecting a frame on a different
10125 text terminal, do not alter the terminal's top-frame.

10128 frame's selected window and its terminal's top-frame.
10129 (unwind_format_mode_line): Restore them.
10130 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10132 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10133 since tty frames can be explicitly named.
10134 (prepare_menu_bars): Likewise.
10136 * term.c (Ftty_top_frame): New function.
10138 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10141 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10142 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10143 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10144 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10145 (METER_1, METER_2): Simplify.
10147 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10149 * data.c (Fdefalias): Return `symbol' (bug#11686).
10151 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10153 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10154 gets killed during executing of this function (Bug#11665).
10155 Try to always return Qt when the buffer has been actually killed.
10156 (Vkill_buffer_query_functions): In doc-string say that functions
10157 run by this hook should not change the current buffer.
10159 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10161 Fix recently-introduced process.c problems found by static checking.

10179 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10181 * lisp.h (eassert): Assume C89 or later.
10182 This removes the need for CHECK.
10183 (CHECK): Remove. Its comments about always evaluating its
10184 argument were confusing, as 'eassert' typically does not evaluate
10187 * coding.c (produce_chars): Use ptrdiff_t, not int.
10189 * xterm.c (x_draw_underwave): Check for integer overflow.
10190 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10377 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10378 Use an inline function on all platforms when using the union type,
10379 since this is simpler and 'static inline' can be used portably

10496 adjust comment accordingly.
10497 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10498 to denote vector blocks. Adjust users (live_vector_p,

10521 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10523 * doprnt.c (doprnt): Truncate multibyte char correctly.
10524 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10525 would mishandle a string argument "Xc" if X was a multibyte
10526 character of length 2: it would truncate after X's first byte
10527 rather than including all of X.
10529 2012-06-06 Chong Yidong <cyd@gnu.org>
10531 * buffer.c (word_wrap): Doc fix.

10578 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10580 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10581 Convert pctcpu and pctmem to Lisp float properly.
10582 Let the compiler fold better, as 100.0/0x8000 is exact.
10584 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10586 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10593 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10595 For a 'struct window', replace some Lisp_Object fields to
10596 bitfields where appropriate, remove unused fields.
10597 * window.h (struct window): Remove unused 'last_mark_x' and
10598 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10599 change its type from Lisp_Object to bitfield.
10600 Change type of 'force_start', 'optional_new_start',
10601 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10602 fields from Lisp_Object to bitfield. Adjust users accordingly.
10604 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10606 Pacify gcc -Wdouble-precision when using Xaw.
10607 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10608 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10609 Use 'float' consistently, rather than 'float' in most places
10610 and 'double' in a couple of places.
10612 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10614 * xdisp.c (handle_stop): Detect whether we have overlay strings
10615 loaded by testing it->current.overlay_string_index to be
10616 non-negative, instead of checking whether n_overlay_strings is
10617 positive. (Bug#11587)
10619 2012-05-31 Chong Yidong <cyd@gnu.org>
10621 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10625 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10627 * search.c (search_buffer): Remove calls to
10628 r_alloc_inhibit_buffer_relocation, as it is now called by
10629 maybe_unify_char, which was the cause of relocation of buffer text
10632 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10634 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10635 for the duration of call to load_charset, to avoid problems with
10636 callers of maybe_unify_char that access buffer text through C
10639 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10640 decrement the inhibition flag, instead of just setting or
10643 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10645 Remove obsolete '#define static' cruft.
10646 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10647 This #undef was "temporary" in 2000; it is no longer needed
10648 now that '#define static' has gone away.
10649 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10650 (gray_bitmap_bits): Remove; no longer needed.
10651 All uses replaced with definiens.
10652 * xterm.c: Include "bitmaps/gray.xbm".
10654 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

10657 The following changes affect the code only when profiling.
10658 * dispnew.c (__executable_start): Rename from safe_bcopy.
10659 Define only on platforms that need it.
10660 * emacs.c: Include <sys/gmon.h> when profiling.
10661 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10662 (__executable_start): Remove decl, since lisp.h does it now.
10663 (safe_bcopy): Remove decl; no longer has that name.
10664 (main): Coalesce #if into single bit of code, for simplicity.
10665 Cast pointers to uintptr_t, since standard libraries want integers
10667 * lisp.h (__executable_start): New decl.
10669 2012-05-31 Glenn Morris <rgm@gnu.org>
10671 * image.c (Fimagemagick_types): Doc fix.

10694 Do not create empty overlays with the evaporate property (Bug#9642).
10695 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10696 Bug#9642, but explicitly check that the buffer the overlay would
10697 be moved to is live and rearrange lines to make sure that errors
10698 will not put the overlay in an inconsistent state.
10699 (Fdelete_overlay): Cosmetics.
10701 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10703 * w32term.c (my_bring_window_to_top): New function.
10704 (x_raise_frame): Use handle returned by DeferWindowPos, which
10705 could be different from the original one.
10706 Call my_bring_window_to_top instead of my_set_foreground_window.

10715 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10717 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10718 This avoids undefined behavior that might cause the eassert
10719 to not catch an out-of-range value.
10721 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10723 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

10737 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10738 Only r_alloc_inhibit_buffer_relocation needed to be added;
10739 the others were already declared.
10741 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10742 before checking whether it's out of range. Put the check inside
10744 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10746 2012-05-27 Ken Brown <kbrown@cornell.edu>

10758 they are now on lisp.h.
10760 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10762 * search.c (search_buffer): Use it to inhibit relocation of buffer
10763 text while re_search_2 is doing its job, because re_search_2 is
10764 passed C pointers to buffer text. (Bug#11519)
10766 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10767 Update value to 24.
10769 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10770 state after an additional call to move_it_in_display_line_to, keep
10771 the values of it->max_ascent and it->max_descent found for the
10773 (pos_visible_p): Revert the comparison against bottom_y to what it
10774 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10777 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10779 Fix coding-related core dumps with gcc -ftrapv.
10780 The code was computing A - B, where A and B are pointers, and B is
10781 random garbage. This can lead to core dumps on platforms that
10782 have special pointer registers, and it also leads to core dumps on
10783 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10784 A - B only when B is initialized properly.
10785 * coding.c (coding_set_source, coding_set_destination): Return void.
10786 (coding_change_source, coding_change_destinations): New functions,
10787 with the old behaviors of coding_set_source and coding_set_destination.

10798 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10800 * w32console.c: Include window.h.
10801 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10803 (initialize_w32_display): Initialize mouse-highlight data.
10805 * w32inevt.c: Include termchar.h and window.h.
10806 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10807 moves, call note_mouse_highlight. If help_echo changed, call
10808 gen_help_event to produce help-echo message in the echo area.
10809 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10812 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10814 * lread.c (read1): Simplify slightly to avoid an overflow warning
10815 with GCC 4.7.0 on x86-64.
10817 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10819 * bidi.c (bidi_mirror_char): Revert last change: an int is
10820 definitely wide enough here.

10832 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10834 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10836 Use int, not EMACS_INT, where int is wide enough.
10837 (inhibit_garbage_collection, Fgarbage_collect):
10838 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10839 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10840 int might not be wide enough.
10841 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10842 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10843 (bidi_at_paragraph_end, bidi_find_paragraph_start)

10851 (overlay_touches_p, struct sortvec, record_overlay_string)
10852 (overlay_strings, recenter_overlay_lists)

10858 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10859 (validate_region): Omit unnecessary test for b <= e,
10860 since that's guaranteed by the previous test.

10862 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10863 (report_overlay_modification):
10864 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10865 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10866 Omit pointer cast, which isn't needed anyway, and doesn't work
10867 after the EMACS_INT -> ptrdiff_t change.
10868 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.

10873 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10874 not int, to avoid needless 32-bit limit on 64-bit hosts.
10875 (exec_byte_code): Use tighter memory-full test, one that checks
10876 for alloca overflow. Don't compute the address of the object just
10877 before an array, as that's not portable. Use EMACS_INT, not
10878 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10879 * callint.c (Fcall_interactively):
10880 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10881 * callproc.c (call_process_kill, Fcall_process):
10882 Don't assume pid_t fits into an Emacs fixnum.

10891 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10892 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10893 (casify_object): Avoid integer overflow when overallocating buffer.
10894 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10895 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10896 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10897 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10898 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10901 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10902 For CCL_MapSingle, check that content and value are in int range.
10903 (ccl_driver, Fregister_code_conversion_map):
10904 Check that Vcode_version_map_vector is a vector.
10905 (resolve_symbol_ccl_program): Check that vector header is in range.
10906 Always copy the vector, so that we can check its contents reliably
10907 now rather than having to recheck each instruction as it's being
10908 executed. Check that vector words fit in 'int'.
10909 (ccl_get_compiled_code, Fregister_ccl_program)
10910 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10911 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10913 contents are in range.
10914 (Fccl_execute_on_string): Check that status is in range.
10915 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10916 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10917 Accept and return EMACS_INT, not int, because callers can pass values
10918 out of 'int' range.

10935 Remove now-unnecessary CHECK_NATNUMs.
10936 (Fdefine_charset_internal): Check ranges here, more carefully.
10937 Don't rely on undefined behavior with signed left shift overflow.
10938 Don't assume unsigned int fits into fixnum, or that fixnum fits
10939 into unsigned int. Don't require max_code to be a valid fixnum;
10940 that's not true for gb10830 4-byte on a 32-bit host. Allow
10941 invalid_code to be a cons, for the same reason. Require code_offset
10942 to be a character. Avoid int overflow if max_char is close
10944 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10945 this is intended anyway and avoids some undefined behavior.
10946 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10947 INDEX_TO_CODE_POINT, as that's what it expects.
10948 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10949 * charset.h (DECODE_CHAR): Return int, not unsigned;
10950 this is what was intended anyway, and it avoids undefined behavior.

10952 integer-overflow issues.
10953 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10954 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10955 where the argument is EMACS_INT, and this behavior is not intended.
10956 * chartab.c (Fmake_char_table, Fset_char_table_range)
10957 (uniprop_get_decoder, uniprop_get_encoder):
10958 Don't assume fixnum fits in int.
10959 * cmds.c (move_point): New function, that does the gist of
10960 Fforward_char and Fbackward_char, but does so while checking
10961 for integer overflow more accurately.
10962 (Fforward_char, Fbackward_char): Use it.
10963 (Fforward_line, Fend_of_line, internal_self_insert)
10964 (internal_self_insert):
10965 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11567 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):

11570 doesn't matter here.
11571 (get_next_display_element, next_element_from_display_vector):
11572 Use int, not EMACS_INT, when int is wide enough.

11612 * xterm.c (x_x_to_emacs_modifiers):
11613 Don't assume EMACS_INT overflows nicely into int.
11614 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11615 may come from Lisp.
11616 (handle_one_xevent): NATNUMP can eval its arg twice.
11617 (x_connection_closed):
11618 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11619 * xterm.h: Adjust decls to match defn changes elsewhere.

11624 2012-05-25 Glenn Morris <rgm@gnu.org>
11626 * lisp.mk (lisp): Update for more files being compiled now.
11628 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11630 * lread.c: Remove `read_pure' which makes no difference.
11631 (read_pure): Remove var.
11632 (unreadpure): Remove function.
11633 (readevalloop): Don't call read_list with -1 flag.
11634 (read1, read_vector): Don't test read_pure any more.
11635 (read_list): Simplify.
11637 * fileio.c, character.h: Minor style tweaks.
11639 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>

11643 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11645 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11646 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11648 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11651 This directory predates autoconf and is no longer needed nowadays.
11652 Move its few remaining bits of functionality to where they're needed.
11653 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11654 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11655 * m/template.h: Remove.
11656 * Makefile.in (M_FILE): Remove. All uses removed.
11657 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11658 * lisp.h (USE_LSB_TAG):
11659 * mem-limits.h (EXCEEDS_LISP_PTR):
11660 Use VAL_MAX, not VALBITS, in #if.
11661 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11662 (EMACS_UINT): Define unconditionally now.
11663 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11664 (BITS_PER_EMACS_INT): New constants, replacing
11665 what used to be in config.h, but not useful in #if.
11666 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11667 define them any more.
11668 (VAL_MAX): New macro.
11670 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11671 BITS_PER_EMACS_INT, in #if.
11672 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11673 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11674 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11675 * s/ms-w32.h (DATA_START):
11676 Move here from removed file m/intel386.h.
11677 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11678 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11680 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11682 Assume C89 or later.
11683 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11684 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11686 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

11692 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11693 * xterm.c (input_signal_count): Assume volatile works.
11695 2012-05-21 Ken Brown <kbrown@cornell.edu>
11697 * xgselect.c (xg_select): Fix first argument in call to 'select'
11700 2012-05-20 Ken Brown <kbrown@cornell.edu>
11702 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11703 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11705 2012-05-19 Ken Brown <kbrown@cornell.edu>
11707 * xfns.c (x_in_use): Remove `static' qualifier.
11708 * xterm.h (x_in_use): Declare.
11709 * xgselect.c: Include xterm.h.
11710 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11711 and `display_arg' (bug#9754).
11713 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11715 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11717 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11718 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11720 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11722 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11724 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11725 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11727 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11728 reference to image_cache->refcount.
11729 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11731 2012-05-17 Juri Linkov <juri@jurta.org>
11733 * search.c (Fword_search_regexp, Fword_search_backward)
11734 (Fword_search_forward, Fword_search_backward_lax)
11735 (Fword_search_forward_lax): Move functions to isearch.el
11736 (bug#10145, bug#11381).
11738 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11740 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11742 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11744 * lread.c (init_obarray): Declare Qt and Qnil as special.
11746 2012-05-14 Glenn Morris <rgm@gnu.org>
11748 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11749 Put "libexec" before "bin", for the sake of init_callproc_1.
11751 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11753 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11755 * unexaix.c: Port to more-recent AIX compilers.
11756 (report_error, report_error_1, make_hdr, copy_sym)
11757 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11758 Make arguments const char *, not char *, to avoid violations of C
11759 standard and to fix some AIX warnings reported by Gilles Pion.
11761 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11763 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11764 already have overlays loaded.
11765 (handle_single_display_spec): Before returning without displaying
11766 fringe bitmap, synchronize the bidi iterator with the main display
11767 iterator, by calling iterate_out_of_display_property.
11768 (iterate_out_of_display_property): Detect buffer iteration by
11769 testing that it->string is a Lisp string.
11770 (get_next_display_element): When the current object is exhausted,
11771 and there's something on it->stack, call set_iterator_to_next to
11772 proceed with what's on the stack, instead of returning zero.
11773 (set_iterator_to_next): If called at the end of a Lisp string,
11774 proceed to consider_string_end without incrementing string
11775 position. Don't increment display vector index past the end of
11776 the display vector. (Bug#11417)
11777 (pos_visible_p): Don't report a position visible when move_it_to
11778 stopped at the last line of window, which happens to be scanned
11779 backwards by the bidi iteration. (Bug#11464)
11781 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11783 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11784 and right-margin display specs even if the spec is invalid or we
11785 are on a TTY, and thus unable to display on the fringes.
11786 That's because the text with the property will not be displayed anyway,
11787 so we need to signal to the caller that this is a "replacing"
11788 display spec. This fixes display when the spec is invalid or we
11791 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11793 * unexaix.c (make_hdr): Fix typo in prototype.
11794 This bug broke the build on AIX. Problem reported by Gilles Pion.
11796 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11798 * keyboard.c (kbd_buffer_get_event): Read special events also in
11799 batch mode. (Bug#11415)
11801 2012-05-12 Glenn Morris <rgm@gnu.org>
11803 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11805 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11807 * lisp.mk (lisp): Add newcomment.elc.
11809 2012-05-12 Glenn Morris <rgm@gnu.org>
11811 * Makefile.in (MKDIR_P): New, set by configure.
11812 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11814 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11816 Remove unused function hourglass_started.
11817 * dispextern.h (hourglass_started):
11818 * w32fns.c (hourglass_started):
11819 * xdisp.c (hourglass_started): Remove.
11821 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11823 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11824 Update dependencies.
11826 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11828 * xgselect.c (xg_select): Put maxfds+1 into a var.
11829 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11831 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11833 2012-05-10 Dave Abrahams <dave@boostpro.com>
11835 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11836 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11838 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11840 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11841 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11842 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11843 Initialize xd_registered_buses.
11845 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11847 Untag more efficiently if USE_LSB_TAG.
11848 This is based on a proposal by YAMAMOTO Mitsuharu in
11849 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11850 For an admittedly artificial (nth 8000 longlist) benchmark on
11851 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11852 Emacs's overall text size by 1%.
11853 * lisp.h (XUNTAG): New macro.
11854 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11855 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11856 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11857 * eval.c (Fautoload):
11858 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11859 * frame.h (XFRAME): Use XUNTAG.
11861 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11862 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11863 Remove unportable assumptions about print widths of types like
11865 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11866 intptr_t when converting between pointer and integer, to avoid GCC
11867 warnings about wrong width.
11869 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11871 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11872 stack for each reader_thread, instead of defaulting to 8MB
11873 determined by the linker. This avoids failures in creating
11874 subprocesses on Windows 7, see the discussion in this thread:
11875 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11877 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11879 Fix up display of the *Minibuf-0* buffer in the mini window.
11880 * keyboard.c (read_char): Don't clear the echo area if there's no
11882 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11883 contents of *Minibuf-0*) if there's no message displayed in its stead.
11885 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11887 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11890 2012-05-06 Chong Yidong <cyd@gnu.org>
11892 * lisp.mk (lisp): Update.
11894 2012-05-05 Jim Meyering <meyering@redhat.com>
11896 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11898 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11900 * data.c (PUT_ERROR): New macro.
11901 (syms_of_data): Use it. Add new error type `user-error'.
11902 * undo.c (user_error): New function.
11903 (Fprimitive_undo): Use it.
11904 * print.c (print_error_message): Adjust print style for `user-error'.
11905 * keyboard.c (user_error): New function.
11906 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11908 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11910 Do not limit current-time-string to years 1000..9999.
11911 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11912 (Fcurrent_time_string): Support any year that is supported by the
11913 underlying localtime representation. Don't use asctime, as it
11914 has undefined behavior for years outside the range -999..9999.
11916 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11918 Fix race conditions involving setenv, gmtime, localtime, asctime.
11919 Without this fix, interrupts could mess up code that uses these
11920 nonreentrant functions, since setting TZ invalidates existing
11921 tm_zone or tzname values, and since most of these functions return
11922 pointers to static storage.
11923 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11924 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11925 Grow the critical sections to include not just invoking
11926 localtime/gmtime, but also accessing these functions' results
11927 including their tm_zone values if any, and any related TZ setting.
11928 (format_time_string): Last arg is now struct tm *, not struct tm **,
11929 so that the struct tm is saved in the critical section.
11930 All callers changed. Simplify allocation of initial buffer, partly
11931 motivated by the fact that memory allocation needs to be outside
11932 the critical section.
11934 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11936 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11937 with RESET_INTERVAL.
11939 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11940 Remove duplicated buffer name initialization.
11942 2012-05-02 Jim Meyering <jim@meyering.net>
11944 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11946 * xfns.c (x_window): Use xstrdup (Bug#11375).
11948 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11950 * xdisp.c (pos_visible_p): If already at a newline from the
11951 display string before the 'while' loop, don't walk back the glyphs
11952 from it3.glyph_row. Solves assertion violation when the display
11953 string begins with a newline (egg.el). (Bug#11367)
11955 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>

11963 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11964 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11965 All were removed before 23.1.
11967 * dispnew.c: Remove HAVE_LIBNCURSES test;
11968 it is always true on relevant platforms.
11970 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

11983 Do not avoid creating empty evaporating overlays (Bug#9642).
11984 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11985 That is, do not delete an evaporating overlay if it becomes
11986 empty after its bounds are adjusted to fit within its buffer.
11987 This fix caused other problems, and I'm reverting it until we get
11988 to the bottom of them.
11990 2012-04-27 Chong Yidong <cyd@gnu.org>
11992 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11994 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11996 * xdisp.c (pos_visible_p): If the window start position is beyond
11997 ZV, start the display from buffer beginning. Prevents assertion
11998 violation in init_iterator when the minibuffer window is scrolled
11999 via the scroll bar.
12001 * window.c (window_scroll_pixel_based): Likewise.
12003 2012-04-27 Chong Yidong <cyd@gnu.org>

12010 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12012 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12014 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12015 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12017 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12019 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12020 display element, check also the underlying string or buffer
12021 character. (Bug#11341)
12023 * w32menu.c: Include w32heap.h.
12024 (add_menu_item): If the call to AppendMenuW (via
12025 unicode_append_menu) fails, disable Unicode menus only if we are
12026 running on Windows 9X/Me.
12028 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12030 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12031 (xgetint): Add missing shift for LSB tags.
12033 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12035 * keyboard.c (read_char): Don't wipe echo area for select window
12036 events: These might get delayed via `mouse-autoselect-window'

12041 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12042 manipulation of :loaded-from data.
12044 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

12047 now a cons (bug#11311).
12049 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12051 Do not create empty overlays with the evaporate property (Bug#9642).
12052 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12053 if it becomes empty after its bounds are adjusted to fit within
12054 its buffer. Without this fix, in a nonempty buffer (let ((o
12055 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12056 yields an empty overlay that has the evaporate property, which is
12057 not supposed to happen.

12174 * sysdep.c [__FreeBSD__]: Minor cleanups.
12175 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12176 Use Emacs indenting style more consistently. Avoid some casts.

12191 It is never used otherwise.
12193 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12195 * print.c (print_preprocess): Only check print_depth if print-circle

12262 (NEED_MEM_INSERT): New macro.
12263 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

12381 attempts per process (connection).
12383 2012-04-09 Chong Yidong <cyd@gnu.org>
12385 * eval.c (Fuser_variable_p, user_variable_p_eh)
12386 (lisp_indirect_variable): Functions deleted.
12387 (Fdefvar): Caller changed.

12390 * minibuf.c (Fread_variable): Callers changed.
12392 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12394 * xdisp.c (set_cursor_from_row): If the display string appears in
12395 the buffer at position that is closer to point than the position
12396 after the display string, display the cursor on the first glyph of
12397 the display string. Fixes cursor display when a 'display' text
12398 property immediately follows invisible text. (Bug#11094)
12400 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12402 composite.c: use 'double' consistently
12403 * composite.c (get_composition_id): Use 'double' consistently
12404 instead of converting 'float' to 'double' and vice versa; this is
12405 easier to understand and avoids a GCC warning.
12407 2012-04-09 Glenn Morris <rgm@gnu.org>
12409 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12410 preparation for dumping it with emacs. (Bug#4789)
12411 (leimdir): New variable.
12412 ($(leimdir)/leim-list.el): New rule.
12413 (emacs$(EXEEXT)): Depend on leim-list.el.

12431 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12432 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12433 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12434 objects, as mark_maybe_pointer will catch them otherwise.
12435 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12436 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12443 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12445 Support building on MS-Windows with libxml2.
12447 * makefile.w32-in (OBJ2): Add xml.$(O).
12448 (GLOBAL_SOURCES): Add xml.c.
12449 ($(BLD)/xml.$(O)): New dependency list.
12451 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.

12454 [!WINDOWSNT]: New macros.
12455 (init_libxml2_functions, libxml2_loaded_p): New functions.
12456 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12457 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12458 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12459 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12461 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12462 Call init_libxml2_functions before calling libxml2 functions.
12463 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12465 * emacs.c: Don't include libxml/parser.h.
12466 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12467 xmlCleanupParser directly.
12469 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12471 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12473 * indent.c (Fvertical_motion): If there is a display string at
12474 point, use it.vpos to compute how many lines to backtrack after
12475 move_it_to point. (Bug#11133)
12477 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12479 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12480 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12481 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12482 macros related to unification of CJK characters. For the details,
12483 see the discussion following the message here:
12484 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12486 2012-04-04 Chong Yidong <cyd@gnu.org>
12488 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12490 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12492 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12493 instead of alloca. (Bug#11138)
12495 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

12500 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12502 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12503 position we get to after a call to move_it_to fails the
12504 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12505 only if we wind up in a string from display property. (Bug#11063)
12507 * window.c (Fdelete_other_windows_internal): Invalidate the row
12508 and column information about mouse highlight, so that redisplay
12509 restores it after reallocating the glyph matrices. (Bug#7464)
12511 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12512 string comes from a `display' text property, use the buffer
12513 position of that property as if we actually saw that position in
12515 (move_it_by_lines): Remove the assertion that
12516 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12517 violated when there's a before-string at the beginning of a line.
12520 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12522 * xdisp.c (append_space_for_newline): If the default face was
12523 remapped, use the remapped face for the appended newline.
12524 (extend_face_to_end_of_line): Use the remapped default face for
12525 extending the face to the end of the line.
12526 (display_line): Call extend_face_to_end_of_line when the default
12527 face was remapped. (Bug#11068)
12529 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12531 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12533 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12535 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12537 2012-03-27 Glenn Morris <rgm@gnu.org>
12539 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12542 2012-03-26 Kenichi Handa <handa@m17n.org>
12544 * dispextern.h (struct glyph): Fix previous change. Change the
12545 bit length of glyphless.ch to 25 (Bug#11082).
12547 2012-03-26 Chong Yidong <cyd@gnu.org>
12549 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12550 (command_loop_1): Use it; inhibit selection update for
12551 handle-select-window too (Bug#8996).
12553 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12555 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12557 2012-03-25 Kenichi Handa <handa@m17n.org>
12559 * dispextern.h (struct glyph): Change the bit length of
12560 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12562 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12564 * s/ms-w32.h (tzname): Include time.h before redirecting to
12565 _tzname. Fixes the MSVC build. (Bug#9960)
12567 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12569 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12572 * xterm.c (XTread_socket): Only modify handling_signal if
12573 !SYNC_INPUT. (Bug#11080)
12575 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12577 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12578 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12579 when fetching a multibyte character consumes more bytes than
12580 CHAR_BYTES returns, due to unification of CJK characters in
12581 string_char. (Bug#11073)
12583 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12585 * process.c (wait_reading_process_output): Handle pty disconnect
12586 by refraining from sending oneself a SIGCHLD (bug#10933).

12593 Mark string as coming from a prefix property.
12594 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12595 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12597 2012-03-21 Chong Yidong <cyd@gnu.org>
12599 * xfaces.c (Vface_remapping_alist): Doc fix.
12601 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12603 * w32proc.c (Fw32_set_console_codepage)
12604 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12607 2012-03-20 Chong Yidong <cyd@gnu.org>
12609 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12610 to reflect default non-nil value of redisplay-dont-pause.
12612 2012-03-19 Kenichi Handa <handa@m17n.org>
12614 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12615 it fit in a valid range (Bug#11003).
12617 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12619 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12620 that is not from display property, accept the row as a "cursor
12621 row" if one of the string's character has a non-nil `cursor'
12622 property. Fixes cursor positioning when there are newlines in
12623 overlay strings, e.g. in icomplete.el. (Bug#11035)
12625 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12627 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12629 2012-03-12 Chong Yidong <cyd@gnu.org>
12631 * eval.c (inhibit_lisp_code): Rename from
12632 inhibit_window_configuration_change_hook; move from window.c.
12634 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12635 * window.c (run_window_configuration_change_hook)
12636 (syms_of_window): Callers changed.

12656 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12659 2012-03-03 Glenn Morris <rgm@gnu.org>
12661 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12663 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12665 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12666 position past the first glyph_row that ends at ZV. (Bug#10902)
12667 (redisplay_window, next_element_from_string): Fix typos in
12669 (redisplay_window): Pass to move_it_vertically the margin in
12670 pixels, not in screen lines.
12672 2012-03-02 Glenn Morris <rgm@gnu.org>
12674 * buffer.c (buffer-list-update-hook): Doc fix.
12676 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12678 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12679 push_it before setting up the iterator for the first overlay
12680 string, even if we have an empty string loaded.
12681 (next_overlay_string): If there's an empty string on the iterator
12682 stack, pop the stack. (Bug#10903)
12684 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12686 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12687 Suggested by Stefan Monnier in
12688 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12689 * alloc.c (widen_to_Lisp_Object): New static function.
12690 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12691 and widening them to Lisp_Objects. This would work even if
12692 USE_LSB_TAG is defined and wide integers are used, which might
12693 happen in a future version of Emacs.
12695 2012-02-25 Chong Yidong <cyd@gnu.org>
12697 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12700 * xselect.c (Fx_selection_exists_p): Doc fix.
12701 (x_clipboard_manager_save_all): Print an informative message
12702 before saving to clipboard manager.
12704 2012-02-24 Chong Yidong <cyd@gnu.org>
12706 * keyboard.c (process_special_events): Handle all X selection
12707 requests in kbd_buffer, not just the next one (Bug#8869).
12709 2012-02-23 Chong Yidong <cyd@gnu.org>
12711 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12712 call when setting menu-bar-lines and tool-bar-lines parameters.
12713 (unwind_create_frame_1): New helper function.
12715 * window.c (inhibit_window_configuration_change_hook): New var.

12734 when computing $valmask.
12736 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12737 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12738 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12739 It's useless in that case, and it can cause problems on hosts
12740 that allocate halves of EMACS_INT values separately.
12741 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12742 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12743 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12744 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12745 it avoids undefined behavior on hosts where shifting right by more
12746 than the word width has undefined behavior.
12748 2012-02-19 Chong Yidong <cyd@gnu.org>
12750 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12751 (Funhandled_file_name_directory, Ffile_name_as_directory)
12752 (Fdirectory_file_name, Fexpand_file_name)
12753 (Fsubstitute_in_file_name): Protect against invalid file handler
12754 return values (Bug#10845).
12756 2012-02-18 Eli Zaretskii <eliz@gnu.org>

12765 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
12767 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
12768 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12770 2012-02-15 Chong Yidong <cyd@gnu.org>
12772 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12773 marked as special. Also, starting docstrings with * is obsolete.

12786 * keymap.c (Fsingle_key_description): Handle char ranges.
12788 2012-02-12 Chong Yidong <cyd@gnu.org>
12790 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12791 as that creates a dangerous corner case.
12793 * window.c (Fdelete_window_internal): Invalidate the mouse
12794 highlight (Bug#9904).
12796 2012-02-12 Glenn Morris <rgm@gnu.org>
12798 * xselect.c (Fx_own_selection_internal)
12799 (Fx_get_selection_internal, Fx_disown_selection_internal)
12800 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12801 * nsselect.m (Fx_own_selection_internal)
12802 (Fx_disown_selection_internal, Fx_selection_exists_p)
12803 (Fx_selection_owner_p, Fx_get_selection_internal):
12804 Sync docs and argument specs with the xselect.c versions.
12806 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12808 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12810 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12812 * w32select.c (Fx_selection_exists_p): Sync doc string and
12813 argument list with xselect.c. (Bug#10783)
12815 * w16select.c (Fx_selection_exists_p): Sync doc string and
12816 argument list with xselect.c. (Bug#10783)

12826 2012-02-07 Chong Yidong <cyd@gnu.org>
12828 * buffer.c (Fbuffer_local_variables)
12829 (buffer_lisp_local_variables): Handle unbound vars correctly;
12830 don't let Qunbound leak into Lisp.
12832 2012-02-07 Glenn Morris <rgm@gnu.org>
12834 * image.c (Fimagemagick_types): Doc fix.
12836 * image.c (imagemagick-render-type): Change it from a lisp object
12837 to an integer. Move the doc here from the lisp manual.
12838 Treat all values not equal to 0 the same.
12840 2012-02-06 Chong Yidong <cyd@gnu.org>
12842 * doc.c (store_function_docstring): Avoid applying docstring of
12843 alias to base function (Bug#2603).

12857 Include --enable-checking, if specified, in the return value.
12859 2012-02-04 Martin Rudalics <rudalics@gmx.at>

13345 (Fword_search_backward_lax, Fword_search_forward_lax):
13346 Use `Fword_search_regexp' instead of `wordify'. Doc fix.
13347 (syms_of_search): Define `Sword_search_regexp'. (Bug#10145)
13349 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
13351 * fileio.c (Finsert_file_contents): Move after-change-function call
13352 to before the "handled:" label, since all "goto handled" appear in
13353 cases where the *-change-functions have already been properly called
13356 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
13358 * keyboard.c (interrupt_signal): Don't call kill-emacs when
13359 waiting for input. (Bug#10169)
13361 2011-11-30 Eli Zaretskii <eliz@gnu.org>
13363 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13364 verifies glyph row's hash code--we have just reallocated the
13365 glyphs, so their contents can be complete garbage. (Bug#10164)
13367 2011-11-30 Juanma Barranquero <lekktu@gmail.com>
13369 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.

13398 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
13399 of scroll runs so as to avoid assigning disabled bogus rows and
13400 unnecessary graphics copy operations.
13402 2011-11-27 Eli Zaretskii <eliz@gnu.org>
13404 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

13410 * lisp.h (GCTYPEBITS): Move before first use.
13411 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13412 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13413 this macro definition.
13415 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
13418 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

13431 Rename locals to avoid shadowing.
13432 * fileio.c (Finsert_file_contents):
13433 Rename inner 'gcpro1' to 'inner_gcpro1' to avoid shadowing.
13434 * process.c (wait_reading_process_output):
13435 Rename inner 'proc' to 'p' to avoid shadowing.
13436 Indent for consistency with usual Emacs style.
13438 2011-11-25 Eli Zaretskii <eliz@gnu.org>
13440 * xdisp.c (redisplay_window): If cursor row is not fully visible
13441 after recentering, and scroll-conservatively is set to a large
13442 number, scroll window by a few more lines to make the cursor fully
13443 visible and out of scroll-margin. (Bug#10105)
13444 (start_display): Don't move to the next line if the display should
13445 start at a newline that is part of a display vector or an overlay
13446 string. (Bug#10119)
13448 2011-11-24 Juri Linkov <juri@jurta.org>
13450 * image.c (imagemagick_load_image): Move `MagickSetResolution' down

13471 2011-11-22 Eli Zaretskii <eliz@gnu.org>
13473 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
13474 and header-lines, as they don't have one computed for them.
13477 * .gdbinit (prow): Make displayed values more self-explaining.
13478 Add row's hash code.
13480 2011-11-21 Lars Magne Ingebrigtsen <larsi@gnus.org>

13523 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
13525 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13526 Otherwise, valgrind does not work on some platforms.
13527 Problem reported by Andreas Schwab in
13528 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13529 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13530 is set, removing the need for VIRT_ADDRESS_VARIES.
13531 (PURE_P): Use a more-efficient implementation that needs just one
13532 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13533 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13534 to 4 (xorl, subq, cmpq, setbe).
13535 * alloc.c (pure): Always extern now, since that's the
13536 VIRT_ADDR_VARIES behavior.
13537 (PURE_POINTER_P): Use a single comparison, not two, for
13538 consistency with the new puresize.h.
13539 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13540 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13541 Remove VIRT_ADDR_VARIES no longer needed.
13543 2011-11-19 Eli Zaretskii <eliz@gnu.org>
13545 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
13546 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13547 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13548 behave as if the cursor position were at the window margin.
13550 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13551 and the cursor position is out of bounds, behave as if the cursor
13552 position were at the window margin. (Bug#10075)
13554 2011-11-18 Chong Yidong <cyd@gnu.org>
13556 * window.c (Fwindow_combination_limit): Make first argument
13557 non-optional, since it is meaningless for live windows like the

13569 2011-11-18 Eli Zaretskii <eliz@gnu.org>
13571 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
13572 hash values of the two rows.
13573 (copy_row_except_pointers): Preserve the used[] arrays and the
13574 hash values of the two rows. (Bug#10035)
13575 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13577 * xdisp.c (row_hash): New function, body extracted from
13578 compute_line_metrics.
13579 (compute_line_metrics): Call row_hash, instead of computing the
13582 * dispnew.c (verify_row_hash): Call row_hash for computing the
13583 hash code of a row, instead of duplicating code from xdisp.c.
13585 * dispextern.h (row_hash): Add prototype.
13587 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13589 * frame.c (delete_frame): Don't delete the terminal when the last
13590 X frame is closed if emacs is built with GTK toolkit.

13610 * window.h (window): Rename slot "nest" to "combination_limit".
13611 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
13612 (Fset_window_nest): Rename to Fset_window_combination_limit.
13613 (Vwindow_nest): Rename to Vwindow_combination_limit.
13614 (recombine_windows, make_parent_window, make_window)
13615 (Fsplit_window_internal, saved_window)
13616 (Fset_window_configuration, save_window_save): Rename all
13617 occurrences of window_nest to window_combination_limit.
13619 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
13621 * image.c (imagemagick_load_image): Fix typo.
13623 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13625 * xdisp.c (display_line): Move the call to
13626 highlight_trailing_whitespace before the call to
13627 compute_line_metrics, since the latter needs to see the final
13628 faces of all the glyphs to compute ROW's hash value.
13629 Fixes assertion violations in row_equal_p. (Bug#10035)
13631 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13633 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13634 just return (bug#10044).
13636 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13638 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13639 with user-defined heap size. Bump the default size of the temacs
13640 heap to 27MB, to avoid memory warning when running temacs.
13641 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13643 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13644 current_matrix and desired_matrix. (Bug#9990)
13645 (verify_row_hash) [XASSERTS]: New function.
13646 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13647 that the hash value of glyph rows is correct.

13663 * nsfns.m (unwind_create_frame):
13664 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
13665 Vframe_list (Bug#9999).

13676 2011-11-11 Johan Bockgård <bojohan@gnu.org>
13678 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
13679 avoid a crash (bug#9496).
13681 2011-11-09 Chong Yidong <cyd@gnu.org>
13683 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13690 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13692 Avoid some portability problems by eschewing 'extern inline' functions.
13693 The trivial performance wins aren't worth the portability hassles; see
13694 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13696 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13697 (window_box_width, window_box_left, window_box_left_offset)
13698 (window_box_right, window_box_right_offset): Undo previous change,
13699 by removing the "extern"s.
13700 * intervals.c (adjust_intervals_for_insertion)
13701 (adjust_intervals_for_deletion): Undo previous change,
13702 making these static again.
13703 (offset_intervals, temp_set_point_both, temp_set_point)
13704 (copy_intervals_to_string): No longer inline.
13705 * xdisp.c (window_text_bottom_y, window_box_width)

13734 (Fset_window_new_total, Fset_window_new_normal)
13735 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
13736 (delete_all_subwindows): Rename to delete_all_child_windows.
13737 (Fdelete_other_windows_internal, Fset_window_configuration):
13738 Call delete_all_child_windows instead of delete_all_subwindows.
13739 * frame.c (delete_frame): Call delete_all_child_windows instead
13740 of delete_all_subwindows.
13742 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
13744 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
13745 This is also needed for porting to any host where GC_MARK_STACK is
13746 not GC_MAKE_GCPROS_NOOPS.
13747 (which_symbols): Use it.
13749 2011-11-07 Kenichi Handa <handa@m17n.org>
13751 * coding.c (coding_set_destination): Check coding->src_pos only
13752 when coding->src_object is a buffer (bug#9910).

13758 process_coding to 0 (bug#9912).
13760 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13762 * xmenu.c (cleanup_widget_value_tree): New function.
13763 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13764 calling free_menubar_widget_value_tree directly (Bug#9830).
13766 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13768 Fix some portability problems with 'inline'.
13769 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13770 (window_box_width, window_box_left, window_box_left_offset)
13771 (window_box_right, window_box_right_offset): Declare extern.
13772 Otherwise, these inline functions do not conform to C99 and
13773 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13774 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13775 * intervals.c (adjust_intervals_for_insertion)
13776 (adjust_intervals_for_deletion): Now extern, because otherwise the
13777 extern inline functions 'offset_intervals' couldn't refer to it.
13778 (static_offset_intervals): Remove.
13779 (offset_intervals): Rewrite using the old contents of
13780 static_offset_intervals. The old version didn't conform to C99
13781 because an extern inline function contained a reference to an
13782 identifier with static linkage.
13784 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13786 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14077 terminal (Bug#6649).
14079 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14081 * dispextern.h (struct bidi_it): New member next_en_type.
14083 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14084 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14085 current character, check also for next_en_type being WEAK_EN.
14086 (bidi_resolve_weak): Don't enter the expensive loop if the current
14087 position is before next_en_pos. Record the bidi type of the first
14088 non-ET, non-BN character we find, in addition to its position.
14089 (bidi_level_of_next_char): Invalidate next_en_type when
14090 next_en_pos is over-stepped.
14092 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14094 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14095 * editfns.c: Rewrite current-time-zone so that it invokes
14096 the equivalent of (format-time-string "%Z") to get the time zone name.
14097 This fixes a bug when the time zone name contains characters that
14098 need converting from the system time locale to Emacs internal format.
14099 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14100 that patch fixed format-time-string to do the conversion, but
14101 I forgot to fix current-time-zone.
14102 (format_time_string): New function, containing most of
14103 what Fformat_time_string used to contain.
14104 (Fformat_time_string): Rewrite in terms of format_time_string.
14105 This doesn't change this function's behavior.
14106 (current-time-zone): Rewrite to use format_time_string.
14107 This fixes the bug reported by Michael Schierl in
14108 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14109 Jason Rumney's 2007-06-07 change worked around this bug, but
14111 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14113 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14115 * xdisp.c (start_display): If the character at POS is displayed
14116 via a display vector, reset IT->current.dpvec_index to zero.
14117 (try_window_reusing_current_matrix): If a line ends in a display
14118 vector or the next line starts in a display vector, continue
14119 redrawing the window even though the character position of
14120 start_row was reached.
14123 2011-10-18 Chong Yidong <cyd@gnu.org>
14125 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14126 with nobreak-char-display too.
14128 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14130 Fix part 3 of bug#9771.
14131 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14132 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14133 non-neutral characters if the current character is a paragraph
14134 separator (a.k.a. Newline). This avoids running the same
14135 expensive loop twice, once when we consume the preceding newline
14136 and the other time when the line actually needs to be displayed.
14137 Avoid the loop when we see neutrals on the base embedding level
14138 following a character whose directionality is the same as the
14139 paragraph's. This avoids running the expensive loop when a line
14140 ends in a long sequence of neutrals, like control characters.
14141 Add assertion against STRONG_AL type. Slightly rearrange code
14142 that determines the type of a neutral given the first non-neutral
14144 (bidi_level_of_next_char): Set next_en_pos to zero when
14145 invalidating its info.
14147 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14149 * xdisp.c (push_display_prop): Determine whether to record string
14150 or buffer position by IT->string, not by IT->method. Allow
14151 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14152 (move_it_vertically_backward): Don't look for character position
14153 immediately after the newline when in a continuation line.
14156 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14158 * window.c (coordinates_in_window): Rewrite and delabelize
14159 vertical border check. (Bug#5357) (Bug#9618)
14161 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14163 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14164 errors in XSetWindowBorder (bug#9310).
14166 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14168 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14169 avoid crash when xmalloc overrun checking is enabled.
14171 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14173 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14174 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14175 cursor motion with <left> and <right> arrow keys.
14177 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14178 some callers set that themselves.
14180 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14182 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14183 display string and the previous row comes from the same string and
14184 is empty. (Bug#9739) (Bug#9738)
14186 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14188 * doc.c (get_doc_string): Encode file name (bug#9735).
14190 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14192 * bidi.c (bidi_level_of_next_char):
14193 * xdisp.c (get_visually_first_element): Remove old incorrect
14194 comments regarding the Unicode Line Separator character.
14196 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14198 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14200 * alloc.c (Fgc_status): Do not access beyond zombies array
14201 boundary if nzombies > MAX_ZOMBIES.
14202 * alloc.c (dump_zombies): Add missing format specifier.
14204 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14206 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14207 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14209 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14210 Some packages use them to denote characters with modifiers.
14212 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14214 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14215 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14216 matching a pp-number. Rename parameter var to var1.
14218 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14220 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14222 2011-10-08 Glenn Morris <rgm@gnu.org>
14224 * callint.c (Fcall_interactively): Give a more explicit error for the
14225 'c' case with a non-character input. (Bug#8479)
14227 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14229 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14231 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14232 lines that are hscrolled on the left.

14235 presence of header-line. (Bug#4426)
14237 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14239 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14240 Don't advertise functionality which we discourage or doesn't work.
14242 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14244 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14245 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14246 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14247 this makes Emacs dump core during garbage collection on rare
14248 occasions. sizeof is obviously inferior to offsetof here, so
14249 stick with offsetof.
14250 (GC_POINTER_ALIGNMENT): New macro.
14251 (mark_memory): Omit 3rd (offset) arg; caller changed.
14252 Don't assume EMACS_INT alignment is the same as pointer alignment.
14254 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14256 * keyboard.c (read_key_sequence_remapped): New var.
14257 (read_key_sequence): Compute remapping in the right buffer.
14258 (command_loop_1): Use read_key_sequence's remapping directly.
14260 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14262 * dired.c (file_name_completion): Don't expand file name.
14263 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14264 before checking file name handler.
14266 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14267 they've been requested explicitly (bug#9591).
14269 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14271 * keymap.c (Fsingle_key_description): Use make_specified_string
14272 instead of build_string to build string from push_key_description.
14275 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14277 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14278 This fixes a Y2038 bug on 64-bit hosts.
14279 * buffer.c (reset_buffer):
14280 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14281 (Fclear_buffer_auto_save_failure):
14282 Use 0, not -1, to represent an unset failure time, since time_t
14283 might not be signed.
14285 Remove dependency on glibc malloc internals.
14286 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14287 Move back here from lisp.h, but with their new implementations.
14288 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14289 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14290 * charset.c (charset_table_init): New static var.
14291 (syms_of_charset): Use it instead of xmalloc. This removes a
14292 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14293 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14294 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14295 Move back to alloc.c.
14296 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14297 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14299 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14301 * nsterm.m (windowDidResize): Call x_set_window_size only when
14302 ns_in_resize is true. Otherwise set pixelwidth/height and
14303 call change_frame_size (Bug#9628).
14305 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14307 Port --enable-checking=all to Fedora 14 x86-64.
14308 * charset.c (syms_of_charset): Also account for glibc malloc's
14309 internal overhead when calculating the initial malloc maximum.
14311 Port --enable-checking=all to Fedora 14 x86.
14312 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14314 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14315 (overrun_check_realloc, overrun_check_free):
14316 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14317 That way, xmalloc returns a properly-aligned pointer even if
14318 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14319 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14320 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14321 into account when calculating the initial malloc maximum.
14322 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14323 Move here from alloc.c, so that charset.c can use it too.
14324 Properly align; the old code wasn't right for common 32-bit hosts
14325 when configured with --enable-checking=all.
14326 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14327 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14329 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14331 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14334 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14336 * xdisp.c (compute_display_string_end): If there's no display
14337 string at CHARPOS, return -1.
14339 * bidi.c (bidi_fetch_char): When compute_display_string_end
14340 returns a negative value, treat the character as a normal
14341 character not covered by a display string. (Bug#9624)
14343 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14345 * lread.c (Fread_from_string): Fix typo in docstring.
14347 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14349 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14350 newline, reseat the iterator instead of bidi-iterating there one
14351 character at a time. (Bug#9610)
14352 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14353 TO_CHARPOS if the bidi iterator is at base embedding level.
14355 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14357 * lread.c (readevalloop): Use correct code for NBSP.
14358 (read1): Likewise. (Bug#9608)
14360 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14362 * dbusbind.c (Fdbus_register_signal): When service is not
14363 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14365 2011-09-25 Glenn Morris <rgm@gnu.org>
14367 * buffer.c (truncate-lines): Doc fix.
14369 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14371 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14372 (Fset_window_next_buffers): Doc fix.
14374 2011-09-24 Glenn Morris <rgm@gnu.org>
14376 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14378 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14380 Fix minor problems found by static checking.
14381 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14382 * indent.c (Fvertical_motion): Fix == vs = typo.
14384 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14386 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14387 Default value is now t. Doc fix.
14389 * indent.c (Fvertical_motion): Compute and apply the overshoot
14390 logic when moving up, not only when moving down. Fix the
14391 confusing name and values of the it_overshoot_expected variable;
14392 logic changes accordingly. (Bug#9254) (Bug#9549)
14394 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14395 CHARPOS is covered by a display string which includes newlines.
14396 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14397 is covered by a display string with embedded newlines.
14399 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14401 * dbusbind.c (Fdbus_register_signal): Add match rule to
14402 Vdbus_registered_objects_table. (Bug#9581)
14403 (Fdbus_register_method, Vdbus_registered_objects_table):
14406 2011-09-24 Jim Meyering <meyering@redhat.com>
14408 do not ignore write error for any output size
14409 The previous change was incomplete.
14410 While it makes emacs --batch detect the vast majority of stdout
14411 write failures, errors were still ignored whenever the output size is
14412 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14413 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14414 && echo FAIL: ignored write error
14415 FAIL: ignored write error
14416 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14417 && echo FAIL: ignored write error
14418 FAIL: ignored write error
14419 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14421 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14423 * emacs.c (Fkill_emacs): In noninteractive mode exit
14424 non-successfully if a write error occurred on stdout. (Bug#9574)
14426 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14428 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14431 * dispextern.h (struct it): Update the comment documenting what
14434 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14436 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14437 a display string, extend search for cursor position to end of row.
14438 (find_row_edges): If the row ends in a newline from a display
14439 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14440 Handle the case of a display string with multiple newlines.
14441 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14442 non-empty line. Fixes confusing cursor motion with arrow keys at
14443 the beginning of a line that starts with whitespace.
14445 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14447 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14450 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14452 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14453 boolean (Bug#9154).
14455 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14457 * xdisp.c (display_line): Record maximum and minimum buffer
14458 positions even if no glyphs were produced (e.g., by a zero-width
14459 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14460 buffer positions that will be removed from the glyph row because
14462 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14463 column is beyond frame width: don't subtract 1 "pixel" when
14464 computing width of the stretch.
14465 (reseat_at_next_visible_line_start): Undo the change made on
14466 2011-09-17 that saved paragraph information and restored it after
14467 the call to `reseat'. (Bug#9545)
14469 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14471 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14472 and turn window cursor on if cleared (Bug#9415).
14474 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14476 * search.c (boyer_moore): Take unibyte characters from pattern
14477 literally. (Bug#9458)
14479 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14481 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14483 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14485 Fix minor problem found by static checking.
14486 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14487 initialized, to pacify gcc -Wuninitialized.
14489 * fileio.c: Report proper errno when syscall falls.
14490 (Finsert_file_contents): Save and restore errno,
14491 so that report_file_error outputs the correct diagnostic.
14492 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14494 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14496 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14498 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14500 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14501 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14503 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14505 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14506 about the current paragraph and restore it after the call to reseat.
14508 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14509 (bidi_find_paragraph_start): Search back for paragraph beginning
14510 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14511 (bidi_move_to_visually_next): Only trigger paragraph-related
14512 computations when the last character is a newline or at EOB, not
14513 just any NEUTRAL_B. (Bug#9470)
14515 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14516 truncated lines if point is covered by a display string. (Bug#9524)
14518 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14520 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14521 (cons_to_x_long): New function.
14522 (lisp_data_to_selection_data): Use it. Correct the test for
14523 short-versus-long data; it was negated. Break out of vector
14524 loop, for efficiency, when a long datum is discovered.
14526 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14528 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14530 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14532 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14533 GCC PR/17406) by declaring this function with external scope.
14535 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14537 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14538 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14540 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14542 * editfns.c (Fformat): Correctly handle text properties on "%%".

14548 * term.c (encode_terminal_code):
14549 * composite.c (composition_update_it, get_composition_id):
14550 * xdisp.c (get_next_display_element)
14551 (fill_composite_glyph_string): Add comments about special meaning
14552 of TAB characters in a composition.
14554 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14556 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14557 This occurs when processing a multibyte format.
14558 Problem reported by Wolfgang Jenker.
14560 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14562 * xdisp.c (try_cursor_movement): Only check for exact match if
14563 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14565 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14567 Remove unused external symbols.
14568 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14569 * xdisp.c (calc_pixel_width_or_height): Now static.
14570 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14571 * indent.c (check_display_width):
14572 * w32term.c: Fix comment to match code.
14573 * xterm.c, xterm.h (x_catching_errors): Remove.
14575 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14577 * xselect.c: Use signed conversions more consistently (Bug#9498).
14578 (selection_data_to_lisp_data): Assume incoming selection data are
14579 signed integers, not unsigned. This is to be consistent with
14580 outgoing selection data, which was modified to use signed integers
14581 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14582 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14583 expects long, not unsigned long.
14585 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14587 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14588 computation of loop end. Reported by Johan Bockgård
14591 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14593 * frame.c (Fother_visible_frames_p): Function deleted.
14595 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14597 * indent.c (compute_motion): Process display vector front to back
14598 rather than the other way around. (Bug#2496)
14600 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14602 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14604 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14606 * minibuf.c (Fread_from_minibuffer): Doc fix.
14608 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14610 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14611 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14613 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14615 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14616 value for non-existent files.
14618 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14620 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14621 set its "size" to -1. This will set the modtime_size field of
14622 the corresponding buffer to -1, which is what
14623 verify-visited-file-modtime expects for files that do not exist.
14626 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14628 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14630 * lisp.h: ... from here. push_key_description is no longer
14631 defined in keyboard.c, so its declaration should not be in
14632 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14633 logically belongs with push_key_description.
14635 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14637 * buffer.h: Include <sys/types.h> instead of <time.h>.
14638 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14639 Problem reported by Herbert J. Skuhra.
14641 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14643 * xml.c (parse_region): Make the parsing work for
14644 non-comment-starting XML files again (bug#9144).
14646 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14648 * image.c (gif_load): Fix calculation of bottom and right corner.
14651 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14653 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14654 redisplay in small windows.
14656 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14658 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14660 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14662 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14663 Operate on live windows only.
14665 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14667 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14669 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14671 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14672 only under bidi iteration.
14674 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14676 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14678 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14680 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14681 Without this fix, the command to link temacs failed due to an
14682 undefined symbol __builtin_isnan. This is because
14683 /usr/include/iso/math_c99.h #defines isnan(x) to
14684 __builtin_isnan(x), but the bundled gcc, which identifies itself
14685 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14687 * floatfns.c (isnan): #undef, and then #define to a clone of
14689 (Fisnan): Always define, since it's always available now.
14690 (syms_of_floatfns): Always define isnan at the Lisp level.
14692 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14694 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14696 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14698 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14699 The previous code assumed that file offsets (off_t values) fit in
14700 EMACS_INT variables, which is not true on typical 32-bit hosts.
14701 The code messed up by falsely reporting buffer overflow in cases
14702 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14703 when "big" contains more than 2**29 bytes, even though this
14704 inserts just one byte and does not overflow the buffer.
14705 (Finsert_file_contents): Store file offsets as off_t
14706 values, not as EMACS_INT values. Check for overflow when
14707 converting between EMACS_INT and off_t. When checking for
14708 buffer overflow or for overlap, take the offsets into account.
14709 Don't use EMACS_INT for small values where int suffices.
14710 When checking for overlap, fix a typo: ZV was used where
14711 ZV_BYTE was intended.
14712 (Fwrite_region): Don't assume off_t fits into 'long'.
14713 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14715 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14717 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14719 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14721 sprintf-related integer and memory overflow issues (Bug#9412).
14723 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14724 (esprintf, exprintf, evxprintf): New functions.
14725 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14726 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14727 (modify_event_symbol): Do not assume that the length of
14728 name_alist_or_stem is safe to alloca and fits in int.
14729 (Fexecute_extended_command): Likewise for function name and binding.
14730 (Frecursion_depth): Wrap around reliably on integer overflow.
14731 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14732 since some callers pass EMACS_INT values.
14733 (Fsingle_key_description): Don't crash if symbol name contains more
14734 than MAX_ALLOCA bytes.
14735 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14736 (get_minibuffer): Arg is now EMACS_INT, not int.
14737 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14738 (esprintf, exprintf, evxprintf): New decls.
14739 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14741 * dbusbind.c (signature_cat): New function.
14742 (xd_signature, Fdbus_register_signal):
14743 Do not overrun buffer; instead, report string overflow.
14745 * dispnew.c (add_window_display_history): Don't overrun buffer.
14746 Truncate instead; this is OK since it's just a log.
14748 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14749 even if the time zone offset is outlandishly large.
14750 Don't mishandle offset == INT_MIN.
14752 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14753 when creating daemon; the previous buffer-overflow check was incorrect.
14755 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14756 which has the guts of the old verror function.
14758 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14759 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14761 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14762 (font_unparse_xlfd): Don't blindly alloca long strings.
14763 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14764 fits in int, when using sprintf. Use single snprintf to count
14765 length of string rather than counting it via multiple sprintfs;
14766 that's simpler and more reliable.
14767 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14768 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14769 sprintf, in case result does not fit in int.
14771 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14772 (fontset_from_font): Print it.
14774 * frame.c (tty_frame_count): Now printmax_t, not int.
14775 (make_terminal_frame, set_term_frame_name): Print it.
14776 (x_report_frame_params): In X, window IDs are unsigned long,
14777 not signed long, so print them as unsigned.
14778 (validate_x_resource_name): Check for implausibly long names,
14779 and don't assume name length fits in 'int'.
14780 (x_get_resource_string): Don't blindly alloca invocation name;
14781 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14784 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14785 (xg_check_special_colors, xg_set_geometry):
14786 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14788 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14789 Use esprintf, not sprintf, in case result does not fit in int.
14791 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14792 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14793 it as a large positive number.
14794 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14795 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14797 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14798 in case result does not fit in int.
14800 * print.c (float_to_string): Detect width overflow more reliably.
14801 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14802 buffer overrun. Don't assume list length fits in 'int'. Treat
14803 print length of 0 as 0, not as infinity; to be consistent with other
14804 uses of print length in this function. Don't overflow print length
14805 index. Don't assume hash table size fits in 'long', or that
14806 vectorlike size fits in 'unsigned long'.
14808 * process.c (make_process): Use printmax_t, not int, to format
14809 process-name gensyms.
14811 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14813 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14814 to avoid potential buffer overrun.
14816 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14817 if X resource line is longer than 512 bytes.
14819 * xfns.c (x_window): Make sprintf buffer a bit bigger
14820 to avoid potential buffer overrun.
14822 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14824 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14826 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14828 Integer overflow fixes for scrolling, etc.
14829 Without these, Emacs silently mishandles large integers sometimes.
14830 For example, "C-u 4294967297 M-x recenter" was treated as if
14831 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14833 * xdisp.c (try_window_id): Check Emacs fixnum range before
14834 converting to 'int'.
14836 * window.c (window_scroll_line_based, Frecenter):
14837 Check that an Emacs fixnum is in range before assigning it to 'int'.
14838 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14839 values converted from Emacs fixnums.
14840 (Frecenter): Don't wrap around a line count if it is out of 'int'
14841 range; instead, treat it as an extreme value.
14842 (Fset_window_configuration, compare_window_configurations):
14843 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14845 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14846 that can exceed INT_MAX. Check that EMACS_INT value is in range
14847 before assigning it to the (possibly-narrower) index.
14848 (match_limit): Don't assume that a fixnum can fit in 'int'.
14850 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14853 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14854 (Fvertical_motion): Don't wrap around LINES values that don't fit
14855 in 'int'. Instead, treat them as extreme values. This is good
14856 enough for windows, which can't have more than INT_MAX lines anyway.
14858 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14860 * Require libxml/parser.h to avoid compilation warning.
14862 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14864 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14865 since this reportedly can destroy thread storage.
14867 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14869 * syntax.c (find_defun_start): Update all cache variables if
14870 exiting early (Bug#9401).
14872 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14874 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14876 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14877 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14878 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14880 * term.c (tty_append_glyph): New function.
14881 (produce_stretch_glyph): Static function and its prototype deleted.
14883 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14886 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14888 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14889 when checking :margin (Bug#9390).
14890 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14891 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14892 so that the name doesn't mislead. All uses changed.
14894 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14896 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14899 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14901 * xdisp.c (move_it_to): Don't bail out early when reaching
14902 position beyond to_charpos, if we are scanning backwards.
14903 (move_it_vertically_backward): When DY == 0, make sure we get to
14904 the first character in the line after the newline.
14906 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14908 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14909 (ccl_driver): Do not generate an out-of-range pointer.
14910 (Fccl_execute_on_string): Remove unnecessary check for
14911 integer overflow, noted by Stefan Monnier in
14912 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14913 Remove a FIXME that didn't need fixing.
14914 Simplify the newly-introduced buffer reallocation code.
14916 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14918 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14920 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14922 Integer and memory overflow issues (Bug#9196).
14924 * doc.c (get_doc_string): Rework so that
14925 get_doc_string_buffer_size is the actual buffer size, rather than
14926 being 1 less than the actual buffer size; this makes xpalloc more
14929 * image.c (x_allocate_bitmap_record, cache_image):
14930 * xselect.c (Fx_register_dnd_atom):
14931 Simplify previous changes by using xpalloc.
14933 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14934 since either will do and ptrdiff_t is convenient with xpalloc.
14936 * charset.c (charset_table_size)
14937 (struct charset_sort_data.priority): Now ptrdiff_t.
14938 (charset_compare): Don't overflow if priorities differ greatly.
14939 (Fsort_charsets): Don't assume list length fits in int.
14940 Check for size-calculation overflow when allocating sort data.
14941 (syms_of_charset): Allocate an initial charset table that is
14942 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14944 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14946 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14947 The actual value is always <= INT_MAX, and leaving it unsigned made
14948 overflow checking harder.
14950 * dispextern.h (struct glyph_matrix.rows_allocated)
14951 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14952 with xpalloc. The values are still always <= INT_MAX.
14954 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14956 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14957 (SAFE_NALLOCA): New macro.
14959 * region-cache.c (struct boundary.pos, find_cache_boundary)
14960 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14961 (set_cache_region, invalidate_region_cache)
14962 (revalidate_region_cache, know_region_cache, region_cache_forward)
14963 (region_cache_backward, pp_cache):
14964 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14965 so that ptrdiff_t * can be passed to xpalloc.
14966 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14967 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14968 (pp_cache): Don't assume cache_len fits in int.
14969 * region-cache.h: Adjust extern decls to match.
14971 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14972 EMACS_INT, since either will do, for xpalloc.
14974 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14975 (xnmalloc, xnrealloc, xpalloc): New functions.
14977 * bidi.c (bidi_shelve_header_size): New constant.
14978 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14979 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14981 * bidi.c (bidi_cache_shrink):
14982 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14984 Don't update size of array until after memory allocation succeeds,
14985 because xmalloc/xrealloc may not return.
14986 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14987 now that we have proper integer overflow checking.
14988 (record_overlay_string, overlay_strings): Catch overflows when
14989 calculating size of overlay_str_buf.
14991 * callproc.c (Fcall_process): Check for size overflow when
14992 calculating size of args2.
14993 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14994 Normally we prefer signed values, but sticking with ptrdiff_t would
14995 require adding more-complicated checks.
14997 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14998 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14999 Redo buffer-overflow calculations to avoid integer overflow.
15000 Add a FIXME comment where memory seems to be over-allocated.
15002 * character.c (Fstring): Check for size-calculation overflow.
15004 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15005 unnecessary integer overflow. Check for size overflow.
15006 (encode_coding_object): Don't update size until xmalloc succeeds.
15008 * composite.c (get_composition_id): Check for overflow in glyph
15009 length calculations.
15011 Integer and memory overflow fixes for display code.
15012 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15013 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15014 (scrolling_window): Check for overflow in size calculations.
15015 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15016 Don't assume glyph table len fits in int.

15018 (row_table_size): Now ptrdiff_t, not int.
15019 (scrolling_window): Avoid overflow in size calculations.
15020 Don't update size until allocation succeeds.
15021 * fns.c (concat): Check for overflow in size calculations.
15022 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15023 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15026 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15027 (get_doc_string): Check for size calculation overflow.
15028 Don't update size until allocation succeeds.
15029 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15030 EMACS_INT, where ptrdiff_t will do.
15031 (Fsubstitute_command_keys): Check for string overflow.

15035 (message_length): Now ptrdiff_t, not int.

15037 Don't assume message length fits in int.
15038 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15040 * emacs.c (main): Do not reallocate argv, since there is a null at
15041 the end that can be overwritten, and this way there's no need to
15042 worry about size-calculation overflow.
15043 (sort_args): Check for size-calculation overflow.
15045 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15047 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15049 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15050 (x_set_scroll_bar_width, x_figure_window_size):
15051 Check for integer overflow.
15052 (x_set_alpha): Do not assume XINT fits in int.
15054 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15055 This is for the members text_lines, text_cols, total_lines, total_cols,
15056 where the system imposes an 'int' limit.
15058 * fringe.c (Fdefine_fringe_bitmap):
15059 Don't update size until alloc works.
15061 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15062 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15064 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15065 Check for size-calculation overflow.
15066 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15067 do, as we prefer signed integers.
15068 (id_to_widget.max_size, id_to_widget.used)
15069 (xg_store_widget_in_map, xg_remove_widget_from_map)
15070 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15071 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15072 Use and return ptrdiff_t, not int.
15073 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15074 * gtkutil.h: Change prototypes to match the above.
15076 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15077 are duplicate now that they've been promoted to lisp.h.
15078 (x_allocate_bitmap_record, x_alloc_image_color)
15079 (make_image_cache, cache_image, xpm_load):
15080 Don't update size until alloc is done.
15081 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

15090 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15091 Use ptrdiff_t, not int, to count maps.

15123 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15124 for command line length. Do not attempt to address one before the
15125 beginning of an array, as that's not portable.

15128 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15130 (encode_terminal_code, calculate_costs): Check for size
15131 calculation overflow.
15132 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

15149 Use ptrdiff_t, not int, for sizes.
15150 (store_mode_line_noprop_char): Don't update size until alloc done.

15157 memory exhaustion (the usual treatment), rather than aborting.
15159 * xfns.c (x_encode_text, x_set_name_internal)
15160 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15161 sizes, since they can exceed INT_MAX in size. Check for size
15162 calculation overflow.
15164 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15165 (xg_select): Check for size calculation overflow.
15166 Don't update size until alloc done.
15168 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15169 as sprintf is limited to int lengths.
15171 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15172 (X_LONG_MIN): New macros.
15173 Use them to make the following changes clearer.
15174 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15175 This change doesn't affect the value now, but it may help remind
15176 future maintainers not to raise the value too much later.
15177 (SELECTION_QUANTUM): Remove, replacing with ...
15178 (selection_quantum): ... new function, which avoids overflow.
15180 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15181 assumption that selection length fits in 'int'.
15182 (x_reply_selection_request, x_handle_selection_request)
15183 (x_get_window_property, receive_incremental_selection)
15184 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15185 (lisp_data_to_selection_data, clean_local_selection_data):
15186 Use ptrdiff_t, not int, to record length of selection.
15187 (x_reply_selection_request, x_get_window_property)
15188 (receive_incremental_selection, x_property_data_to_lisp):
15189 Redo calculations to avoid overflow.
15190 (x_reply_selection_request): When sending hint, ceiling it at
15191 X_LONG_MAX rather than relying on wraparound overflow to send
15193 (x_get_window_property, receive_incremental_selection)
15194 (lisp_data_to_selection_data, x_property_data_to_lisp):
15195 Check for size-calculation overflow.

15198 Don't store size until memory allocation succeeds.
15199 (x_get_window_property): Plug memory leak on memory exhaustion.
15200 Don't double-block input; malloc is safe here. Don't assume 2**34
15201 - 4 fits in unsigned long. Add an xassert to check
15202 XGetWindowProperty overflow. Be more careful about overflow
15203 calculations, and distinguish size from memory overflow better.
15204 (receive_incremental_selection): When tracing, don't assume
15205 unsigned int is less than INT_MAX.
15206 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15207 harmful) conversions of unsigned short to int.
15208 (lisp_data_to_selection_data): Don't assume that integers
15209 in the range -65535 through -1 fit in an X unsigned short.
15210 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15211 result parameters unless successful. Rely on cons_to_unsigned
15212 to report problems with elements; the old code wasn't right anyway.
15213 (x_check_property_data): Check for int overflow; we cannot use
15214 a wider type due to X limits.
15215 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15217 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15219 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15220 (x_term_init): Check for size calculation overflow.
15221 (x_color_cells): Don't store size until memory allocation succeeds.
15222 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15223 Don't assume alloca size is less than MAX_ALLOCA.
15224 (x_term_init): Don't assume length fits in int (sprintf is limited
15227 Use ptrdiff_t for composition IDs.
15228 * character.c (lisp_string_width):
15229 * composite.c (composition_table_size, n_compositions)
15230 (get_composition_id, composition_gstring_from_id):

15246 * image.c (xpm_get_color_table_h):
15247 * lisp.h (hash_lookup, hash_put):
15248 * minibuf.c (Ftest_completion):
15249 Use ptrdiff_t for hash table indexes, not int (which is too
15250 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15251 32-bit --with-wide-int hosts).
15253 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15254 Add a FIXME comment about memory leaks.
15255 (syms_of_charset): Don't assume xmalloc returns.
15257 Don't assume that stated character widths fit in int.

15259 * character.h (CHAR_WIDTH):
15260 * indent.c (MULTIBYTE_BYTES_WIDTH):
15261 Use sanitize_char_width to avoid undefined and/or bad behavior
15262 with outlandish widths.
15263 * character.h (sanitize_tab_width): Rename from sanitize_width,
15264 now that we have two such functions. All uses changed.
15265 (sanitize_char_width): New inline function.
15267 Don't assume that tab-width fits in int.
15268 * character.h (sanitize_width): New inline function.
15269 (SANE_TAB_WIDTH): New macro.
15270 (ASCII_CHAR_WIDTH): Use it.

15275 * fileio.c: Integer overflow issues with file modes.
15276 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15278 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15279 Remove unreachable code.
15280 (read_hex, load_charset_map_from_file): Check for integer overflow.
15282 * xterm.c: Don't go over XClientMessageEvent limit.
15283 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15284 (x_send_scroll_bar_event): Likewise. Check that the size does not
15285 exceed limits imposed by XClientMessageEvent, as well as the usual
15286 ptrdiff_t and size_t limits.
15288 * keyboard.c: Overflow, signedness and related fixes.
15289 (make_lispy_movement): Use same integer type in forward decl
15290 that is used in the definition.
15291 (read_key_sequence, keyremap_step):
15292 Change bufsize argument back to int, undoing my 2011-03-30 change.
15293 We prefer signed types, and int is wide enough here.
15294 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15295 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15296 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15297 length, not size_t. Use ptrdiff_t for index, not int.
15298 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15299 possibility of integer overflow.
15301 Overflow, signedness and related fixes for images.
15303 * dispextern.h (struct it.stack[0].u.image.image_id)
15304 (struct_it.image_id, struct image.id, struct image_cache.size)

15311 * xdisp.c (calc_pixel_width_or_height):
15312 * xfns.c (image_cache_refcount):
15313 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

15320 when the callers expect that.
15321 (image_ascent): Redo ascent calculation to avoid int overflow.
15322 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15323 (lookup_image): Remove unnecessary tests.
15324 (xbm_image_p): Locals are now of int, not EMACS_INT,
15325 since parse_image_check makes sure they fit into int.
15326 (png_load, gif_load, svg_load_image):
15327 Prefer int to unsigned where either will do.
15328 (tiff_handler): New function, combining the cores of the
15329 old tiff_error_handler and tiff_warning_handler.
15330 This function is rewritten to use vsnprintf and thereby avoid
15331 stack buffer overflows. It uses only the features of vsnprintf
15332 that are common to both POSIX and native Microsoft.
15333 (tiff_error_handler, tiff_warning_handler): Use it.
15334 (tiff_load, gif_load, imagemagick_load_image):
15335 Don't assume :index value fits in 'int'.
15336 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15337 (imagemagick_load_image): Check that crop parameters fit into
15338 the integer types that MagickCropImage accepts. Don't assume
15339 Vimagemagick_render_type has a nonnegative value. Don't assume
15340 size_t fits in 'long'.
15341 (gs_load): Use printmax_t to print the widest integers possible.
15342 Check for integer overflow when computing image height and width.
15344 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15346 * xdisp.c (redisplay_window): Don't force window start if point
15347 will be invisible in the resulting window. (Bug#9324)

15351 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15352 the display spec is of the form `(space ...)'.
15353 (handle_display_spec): Return the value returned by
15354 handle_single_display_spec, not just 1 or zero.
15355 (handle_single_display_spec): If the display spec is of the form
15356 `(space ...)', and specifies display in the text area, return 2
15358 (try_cursor_movement): Check for the need to scroll more
15359 accurately, and prefer exact match for point under bidi.
15360 Don't advance `row' beyond the last row of the window.
15362 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15363 into disp_prop; all users changed.
15365 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15366 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15367 for the text covered by the display property.

15377 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15378 buffers, return left-to-right.
15379 (set_cursor_from_row): Consider candidate row a win if its glyph
15380 represents a newline and point is on that newline. Fixes cursor
15381 positioning on the newline at EOL of R2L text within L2R
15382 paragraph, and vice versa.
15383 (try_cursor_movement): Check continued rows, in addition to
15384 continuation rows. Fixes unwarranted scroll when point enters a
15385 continued line of R2L text within an L2R paragraph, or vice versa.
15386 (cursor_row_p): Consider the case of point being equal to
15387 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15388 from the end of a short line to the beginning of a continued line
15389 of R2L text within L2R paragraph.
15390 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15391 composed characters.

15406 2011-08-22 Kenichi Handa <handa@m17n.org>
15408 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15409 extra slot even if the purpose is char-code-property-table.
15411 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15413 * xdisp.c (redisplay_window): When computing centering_position,
15414 account for the height of the header line. (Bug#8874)
15416 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15417 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15418 candidate is selected by the mouse, and that candidate has a
15419 composed character under the mouse.
15421 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15422 coordinates reported by pos-visible-in-window-p for a composed
15423 character in column zero.
15425 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15427 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15429 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15431 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15432 consider it a hit if to_charpos is anywhere in the range of the
15433 composed buffer positions.
15435 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15437 * image.c (gif_load): Don't assume that each subimage has the same
15438 dimensions as the base image. Handle disposal method that is
15439 "undefined" by the gif spec (Bug#9335).
15441 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15443 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15448 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15449 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15450 from an Org mode buffer to a Speedbar frame.
15452 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15453 a composition, take its buffer position from IT->cmp_it.charpos.
15454 Fixes cursor positioning at the beginning of a line that begins
15455 with a composed character.
15457 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15459 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15460 character bidirectional type, use STRONG_L instead. Fixes crashes
15461 in a buffer produced by `describe-categories'.
15463 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15464 members before the level stack, so they would be saved and
15465 restored when copying iterator state. Fixes incorrect reordering
15466 around TABs covered by display properties.
15468 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15470 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15494 Fix memory allocation problems in Cygwin build (Bug#9273).
15496 * unexcw.c ( __malloc_initialized): Declare external variable.
15497 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15499 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15501 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15540 * xdisp.c (move_it_in_display_line_to): Don't invoke
15541 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15542 ppos_it. Fixes vertical cursor motion when line beginning is
15543 covered by an image. (Bug#9296)
15545 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15547 * nsterm.h (ns_run_ascript): Declare.

15551 (ns_run_ascript): New function.
15552 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15553 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15554 the event loop. Get status from as_status (Bug#7276).
15556 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15557 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15558 the event loop (Bug#7276).
15560 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15562 * gnutls.c (QCgnutls_bootprop_priority)

15583 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15584 (Fnetwork_interface_list): Allocate in increments of bytes instead
15585 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15586 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15588 (struct ifflag_def): notrailers is smart on OSX.
15589 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15590 Get hardware address with getifaddrs if available.
15592 2011-08-12 Eli Zaretskii <eliz@gnu.org>

15595 IT->position is set to within IT->object's boundaries. Break from
15596 the loop as soon as EOB is reached; avoids infloops in redisplay
15597 when IT->position is set up wrongly due to some bug.
15598 Set IT->current to match the bidi iterator unconditionally.
15599 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15600 entry. Force push_it to save on the stack the current
15601 buffer/string position, to be restored by pop_it. Fix flags in
15602 the iterator structure wrt the object coming from a display
15603 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15604 properties. (Bug#9284)
15606 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15608 * fontset.c (fontset_get_font_group): Add proper type checks.
15611 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15613 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
15614 and LC_VERSION_MIN_MACOSX.
15615 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
15616 (dump_it) [LC_FUNCTION_STARTS]: Use it.
15618 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15620 * xdisp.c (forward_to_next_line_start): Allow to use the
15621 no-display-properties-and-no-overlays under bidi display.
15622 Set disp_pos in the bidi iterator to avoid searches for display
15623 properties and overlays.
15625 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15627 * editfns.c (Fset_time_zone_rule): Document relationship with the
15630 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15631 the font entity extracted from the cache (Bug#8109).
15633 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15635 * composite.c (autocmp_chars): Don't reset point. That is done by
15636 restore_point_unwind (Bug#5984).
15638 2011-08-07 Juri Linkov <juri@jurta.org>
15640 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15641 to show the arg `TIME' instead of `TIMEVAL'.
15643 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15645 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15646 display property strides EOL and includes a newline, as in
15647 longlines-mode. (Bug#9254)
15648 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15649 word-wrap under bidirectional display. (Bug#9224)
15651 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15652 is non-zero, even if the data buffer is NULL. Fixes a crash in
15653 vertical-motion with longlines-mode. (Bug#9254)
15655 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15657 * bidi.c <bidi_cache_total_alloc>: Now static.
15658 (bidi_initialize): Initialize bidi_cache_total_alloc.
15660 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15663 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15664 amount allocated this far in `bidi_cache_total_alloc'.
15665 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15666 non-zero, only free the data buffer without restoring the cache
15667 contents. All callers changed.
15669 * dispextern.h (bidi_unshelve_cache): Update prototype.
15671 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15672 (move_it_in_display_line, move_it_to)
15673 (move_it_vertically_backward, move_it_by_lines): Replace the call
15674 to xfree to an equivalent call to bidi_unshelve_cache.
15675 (move_it_in_display_line_to): Fix logic of returning
15676 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15678 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15680 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15681 came from a string character with a `cursor' property. (Bug#9229)
15683 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15685 * Makefile.in (LIB_PTHREAD): New variable.
15686 (LIBES): Add LIB_PTHREAD (Bug#9216).
15688 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15689 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15691 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15693 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15695 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15697 * xterm.c (x_find_topmost_parent): New function.
15698 (x_set_frame_alpha): Find topmost parent window with
15699 x_find_topmost_parent and set the property there also (bug#9181).
15700 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15702 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15704 * callproc.c (Fcall_process): Avoid vfork clobbering
15705 the local vars buffer, coding_systems, current_dir.
15707 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15709 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15711 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15713 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15714 so that it is not optimized away.
15716 * xdisp.c (compute_display_string_pos): Remove unused local.
15718 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15720 Fix slow cursor motion and scrolling in large buffers with
15721 selective display, like Org Mode buffers. (Bug#9218)
15723 * dispextern.h (struct bidi_it): New member disp_prop_p.
15725 * xdisp.c: Remove one-slot cache of display string positions.
15726 (compute_display_string_pos): Accept an additional argument
15727 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15728 for a display string or property. If found, set DISP_PROP_P
15731 * bidi.c (bidi_fetch_char): Accept an additional argument
15732 DISP_PROP_P, and pass it to compute_display_string_pos.
15733 Only handle text covered by a display string if DISP_PROP_P is returned
15734 non-zero. All callers of bidi_fetch_char changed.
15736 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15738 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15740 2010-12-03 Don March <don@ohspite.net>
15742 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15743 last character M-[char] is translated to ESC [char] (bug#7541).
15745 2011-08-02 Kenichi Handa <handa@m17n.org>
15747 * lisp.h (uniprop_table): Extern it.
15749 * chartab.c (uniprop_table): Make it non-static.
15751 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15753 * xdisp.c (forward_to_next_line_start): Accept additional argument
15754 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15756 (reseat_at_next_visible_line_start): Use the bidi iterator state
15757 returned by forward_to_next_line_start to restore the state of
15758 it->bidi_it after backing up to previous newline. (Bug#9212)
15760 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15762 * regex.c (re_comp): Protoize.
15763 (re_exec): Fix return type.
15764 (regexec): Fix type of `ret'. (Bug#9203)
15766 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15768 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15769 This is needed if max-image-size is a floating-point number.
15771 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15773 * print.c (print_object): Print empty symbol as ##.
15775 * lread.c (read1): Read ## as empty symbol.
15777 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15779 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15780 setting frame foreground color (Bug#9175).
15781 (x_set_background_color): Likewise.
15783 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15784 contents (Bug#9176).
15785 (EmacsTooltip -init): Remove bezels and add shadows to
15788 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15789 or scroll bar (Bug#8470).
15791 * nsfont.m (nsfont_open): Remove assignment to voffset and
15792 unnecessary vars hshink, expand, hd, full_height, min_height.
15793 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15795 * nsterm.h (nsfont_info): Remove voffset field.
15797 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15799 Implement strike-through and overline on NextStep (Bug#8863).
15801 * nsfont.m (nsfont_open): Use underline position provided by font,
15802 instead of hard-coded value of 2.
15803 (nsfont_draw): Call ns_draw_text_decoration instead.
15805 * nsterm.h: Add declaration for ns_draw_text_decoration.
15807 * nsterm.m (ns_draw_text_decoration): New function for drawing
15808 underline, overline, and strike-through.
15809 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15810 ns_draw_text_decoration. Change treatment of cursor drawing to
15811 accommodate underlining, etc.
15813 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15815 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15818 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15820 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15821 Without this fix, if a signal arrives just after memory fills up,
15822 'malloc' might be invoked reentrantly.
15824 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15825 In other words, assume that every image size is allowed, on non-X
15826 hosts. This assumption is probably wrong, but it lets Emacs compile.
15828 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15830 * regex.c (re_iswctype): Convert return values to boolean.
15832 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15834 * xdisp.c (compute_display_string_pos): Don't use cached display
15835 string position if the buffer had its restriction changed.
15838 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15840 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15842 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15844 Integer signedness and overflow and related fixes. (Bug#9079)
15846 * bidi.c: Integer size and overflow fixes.
15847 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15848 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15849 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15850 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15851 (bidi_find_other_level_edge):
15852 Use ptrdiff_t instead of EMACS_INT where either will do.
15853 This works better on 32-bit hosts configured --with-wide-int.
15854 (bidi_cache_ensure_space): Check for size-calculation overflow.
15855 Use % rather than repeated addition, for better worst-case speed.
15856 Don't set bidi_cache_size until after xrealloc returns, because it
15858 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15859 (bidi_cache_ensure_space): Also check that the bidi cache size
15860 does not exceed that of the largest Lisp string or buffer. See Eli
15861 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15863 * alloc.c (__malloc_size_t): Remove.
15864 All uses replaced by size_t. See Andreas Schwab's note
15865 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15867 * image.c: Improve checking for integer overflow.
15868 (check_image_size): Assume that f is nonnull, since
15869 it is always nonnull in practice. This is one less thing to
15870 worry about when checking for integer overflow later.
15871 (x_check_image_size): New function, which checks for integer
15872 overflow issues inside X.
15873 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15874 This removes the need for a memory_full check.
15875 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15876 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15877 (xbm_read_bitmap_data): Change locals back to 'int', since
15878 their values must fit in 'int'.
15879 (xpm_load_image, png_load, tiff_load):
15880 Invoke x_create_x_image_and_pixmap earlier,
15881 to avoid much needless work if the image is too large.
15882 (tiff_load): Treat overly large images as if
15883 x_create_x_image_and_pixmap failed, not as malloc failures.
15884 (gs_load): Use x_check_image_size.
15886 * gtkutil.c: Omit integer casts.
15887 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15888 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15890 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15892 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15893 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15894 would wrongly return t on a 64-bit host.
15896 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15897 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15898 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15899 and therefore cause GCC to emit a bogus diagnostic in some cases.
15901 * image.c: Integer signedness and overflow and related fixes.
15902 This is not an exhaustive set of fixes, but it's time to
15903 record what I've got.
15904 (lookup_pixel_color, check_image_size): Remove redundant decls.
15905 (check_image_size): Don't assume that arbitrary EMACS_INT values
15906 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15907 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15908 (tiff_load, imagemagick_load_image):
15909 Check for overflow in size calculations.
15910 (x_create_x_image_and_pixmap): Remove unnecessary test for
15911 xmalloc returning NULL; that can't happen.
15912 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15913 (xpm_color_bucket): Use better integer hashing function.
15914 (xpm_cache_color): Don't possibly over-allocate memory.
15915 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15916 (gif_memory_source):
15917 Use ptrdiff_t, not int or size_t, to record sizes.
15918 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15919 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15920 either works, as we prefer signed integers.
15921 (tiff_read_from_memory, tiff_write_from_memory):
15922 Return tsize_t, not size_t, since that's what the TIFF API wants.
15923 (tiff_read_from_memory): Don't fail simply because the read would
15924 go past EOF; instead, return a short read.
15925 (tiff_load): Omit no-longer-needed casts.
15926 (Fimagemagick_types): Don't assume size fits into 'int'.
15928 Improve hashing quality when configured --with-wide-int.
15929 * fns.c (hash_string): New function, taken from sxhash_string.
15930 Do not discard information about ASCII character case; this
15931 discarding is no longer needed.
15932 (sxhash-string): Use it. Change sig to match it. Caller changed.
15933 * lisp.h: Declare it.
15934 * lread.c (hash_string): Remove, since we now use fns.c's version.
15935 The fns.c version returns a wider integer if --with-wide-int is
15936 specified, so this should help the quality of the hashing a bit.
15938 * emacs.c: Integer overflow minor fix.
15939 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15940 Define only if GNU_LINUX.
15941 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15943 * dispnew.c: Integer signedness and overflow fixes.
15944 Remove unnecessary forward decls, that were a maintenance hassle.
15945 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15947 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15948 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15949 (prepare_desired_row, line_draw_cost):
15950 Use int, not unsigned, where either works.
15951 (save_current_matrix, restore_current_matrix):
15952 Use ptrdiff_t, not size_t, where either works.
15953 (init_display): Check for overflow more accurately, and without
15954 relying on undefined behavior.
15956 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15957 Remove, replacing with the new symbols in lisp.h. All uses changed.
15958 * fileio.c (make_temp_name):
15959 * filelock.c (lock_file_1, lock_file):
15960 * xdisp.c (message_dolog):
15961 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15962 Use pMd etc. instead.
15963 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15964 replacing the pWIDE etc. symbols removed from editfns.c.
15966 * keyboard.h (num_input_events): Now uintmax_t.
15967 This is (very slightly) less likely to mess up due to wraparound.
15970 * buffer.c: Integer signedness fixes.
15971 (alloc_buffer_text, enlarge_buffer_text):
15972 Use ptrdiff_t rather than size_t when either will do, as we prefer
15975 * alloc.c: Integer signedness and overflow fixes.
15976 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15977 (__malloc_size_t): Default to size_t, not to int.
15978 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15979 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15980 Prefer ptrdiff_t to size_t when either would do, as we prefer
15982 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15983 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15984 Now const. Initialize with values that are in range even if char
15986 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15987 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15988 These functions do the right thing with sizes > 2**32.
15989 (check_depth): Now ptrdiff_t, not int.
15990 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15991 Adjust to new way of storing sizes. Check for size overflow bugs
15993 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15994 slightly wrong anyway, as it missed one instance of
15995 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15996 (refill_memory_reserve): Omit needless cast to size_t.
15997 (mark_object_loop_halt): Mark as externally visible.
15999 * xselect.c: Integer signedness and overflow fixes.
16000 (Fx_register_dnd_atom, x_handle_dnd_message):
16001 Use ptrdiff_t, not size_t, since we prefer signed.
16002 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16003 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16004 x_dnd_atoms_size and x_dnd_atoms_length.
16006 * doprnt.c: Prefer signed to unsigned when either works.
16008 * doprnt.c (doprnt):
16010 * xdisp.c (vmessage):
16011 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16012 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16013 prefer signed arithmetic to avoid comparison confusion.
16014 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16015 but is a bit tricky.
16017 Assume freestanding C89 headers, string.h, stdlib.h.
16018 * data.c, doprnt.c, floatfns.c, print.c:
16019 Include float.h unconditionally.
16020 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16021 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16022 * regex.c: Likewise for stddef.h, string.h.
16023 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16024 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16025 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16026 (STDC_HEADERS): Remove obsolete defines.
16027 * sysdep.c: Include limits.h unconditionally.
16029 Assume support for memcmp, memcpy, memmove, memset.
16030 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16031 * regex.c (memcmp, memcpy):
16032 Remove; we assume C89 now.
16034 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16035 (__malloc_safe_bcopy): Remove; no longer needed.
16037 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16038 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16039 well either way, and we prefer signed to unsigned.
16041 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16043 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16044 closes the connection while we're reading (bug#9182).
16046 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16048 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16049 are specified (Bug#9168).
16051 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16053 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16054 Found by GCC static checking and --with-wide-int on a 32-bit host.
16056 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16058 * xdisp.c (compute_display_string_pos): Fix logic of caching
16059 previous display string position. Initialize cached_prev_pos to
16060 -1. Fixes slow-down at the beginning of a buffer.
16062 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16064 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16065 for attrs[LFACE_FONTSET_INDEX].
16067 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16069 * xml.c (parse_region): Remove unused local
16070 that was recently introduced.
16072 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16074 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16075 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16077 * xdisp.c (move_it_in_display_line_to): Record the best matching
16078 position for TO_CHARPOS while scanning the line, and restore it on
16079 exit if none of the characters scanned was an exact match.
16080 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16081 when exact match is impossible due to invisible text, and the
16082 lines are truncated.
16084 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16086 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16089 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16091 Fix a significant slow-down of cursor motion with C-n, C-p,
16092 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16093 auto-repeat under bidi redisplay in fontified buffers.
16094 * xdisp.c (compute_stop_pos_backwards): New function.
16095 (next_element_from_buffer): Call compute_stop_pos_backwards to
16096 find a suitable prev_stop when we find ourselves before
16098 (reseat): Don't look for prev_stop, as that could mean a very long
16100 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16101 <cached_disp_overlay_modiff>: Cache for last found display string
16103 (compute_display_string_pos): Return the cached position if asked
16104 about the same buffer in the same area of character positions, and
16105 the buffer wasn't changed since the time the display string
16106 position was cached.
16108 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16110 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16111 is an integer, which is important for empty lines. (Bug#9149)
16113 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16115 * frame.c (Fmodify_frame_parameters): In tty case, update the
16116 default face if necessary (Bug#4238).
16118 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16120 * editfns.c (Fstring_to_char): No need to explain what a character
16121 is in the docstring (Bug#6576).
16123 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16125 * xml.c (parse_region): Make sure we always return a tree.
16127 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16129 * xml.c (parse_region): If a document contains only comments,
16132 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16134 * xml.c (make_dom): Return comments, too.
16136 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16139 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16140 and the surrounding thread.
16141 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16142 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16143 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16145 * s/openbsd.h (BROKEN_SIGIO): Define.
16146 * unexelf.c (unexec) [__OpenBSD__]:
16147 Don't update the .mdebug section of the Alpha COFF symbol table.
16149 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16151 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16154 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16156 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16157 This fixes some race conditions on the permissions of any newly
16160 * alloc.c (valid_pointer_p): Use pipe, not open.
16161 This fixes some permissions issues when debugging.
16163 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16164 If fchown fails to set both uid and gid, try to set just gid,
16165 as that is sometimes allowed. Adjust the file's mode to eliminate
16166 setuid or setgid bits that are inappropriate if fchown fails.
16168 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16170 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16171 to compare Lisp_Objects.

16176 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16178 * lread.c (read_integer): Unread even EOF character.
16179 (read1): Likewise. Properly record start position of symbol.
16181 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16182 symbol character follows.
16184 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16186 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16187 This works around a problem with the previous change to Fcopy_file.
16188 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16189 and without this change, GCC might complain about discarding
16190 fchown's return value.
16192 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16194 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16196 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16198 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16200 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16202 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16203 it's used from the C level.
16205 * process.c: Use the same condition for POLL_FOR_INPUT in both
16206 keyboard.c and process.c (bug#1858).
16208 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16210 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16211 (Fgnutls_boot): Use it.
16213 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16215 * doc.c (Fsubstitute_command_keys): Revert last change.
16217 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16219 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16220 quotes the next character, and doesn't affect other longer
16221 sequences (bug#8935).
16223 * lread.c (syms_of_lread): Clarify that is isn't only
16224 `eval-buffer' and `eval-defun' that's affected by
16225 `lexical-binding' (bug#8460).
16227 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16229 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16230 bidi redisplay when a line includes both an image and is truncated.
16232 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16234 Fix minor problems found by static checking.
16235 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16236 (elsz): Now a signed constant, not a size_t var. We prefer signed
16237 types to unsigned, to avoid integer comparison confusion. Without
16238 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16239 "cannot optimize loop, the loop counter may overflow", a symptom
16241 * indent.c (Fvertical_motion): Mark locals as initialized.
16242 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16244 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16246 * search.c (Fre_search_backward): Mention `case-fold-search' in
16247 all the re_search_* functions (bug#8138).

16267 buffer position was specified. Initialize paragraph_embedding to
16269 (reseat_to_string): Initialize the bidi iterator.
16270 (display_string): If we need to ignore text properties of
16271 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16272 original value of -1 will not work with bidi.)
16273 (compute_display_string_pos): First arg is now struct
16274 `text_pos *'; all callers changed. Support display properties on
16276 (compute_display_string_end): Support display properties on Lisp
16278 (init_iterator, reseat_1, reseat_to_string): Initialize the
16279 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16280 when iterating on a string not from display properties).
16281 (compute_display_string_pos, compute_display_string_end):
16282 Fix calculation of the object to scan. Fixes an error when using
16284 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16285 base_level_stop; instead, set base_level_stop to BEGV.
16286 Fixes crashes in vertical-motion.
16287 (next_element_from_buffer): Improve commentary for when
16288 the iterator is before prev_stop.
16289 (init_iterator): Initialize bidi_p from the default value of
16290 bidi-display-reordering, not from buffer-local value. Use the
16291 buffer-local value only if initializing for buffer iteration.
16292 (handle_invisible_prop): Support invisible properties on strings
16293 that are being bidi-reordered.
16294 (set_iterator_to_next): Support bidi reordering of C strings and

16300 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16301 (init_iterator): Don't initialize it->bidi_p for strings
16303 (reseat_to_string): Initialize it->bidi_p for strings here.

16310 character that is not the first one in the visual order.
16311 (get_visually_first_element): New function, refactored from common
16312 parts of next_element_from_buffer, next_element_from_string, and
16313 next_element_from_c_string.
16314 (tool_bar_lines_needed, redisplay_tool_bar)
16315 (display_menu_bar): Force left-to-right direction. Add a FIXME
16316 comment for making that be controlled by a user option.
16317 (push_it, pop_it): Save and restore the state of the
16318 bidi iterator. Save and restore the bidi_p flag.
16319 (pop_it): Iterate out of display property for string iteration as

16322 (handle_single_display_spec): Set up it->bidi_it for iteration
16323 over a display string, and call bidi_init_it.

16325 (get_overlay_strings_1, push_display_prop): Set up the bidi
16326 iterator for displaying display or overlay strings.
16327 (forward_to_next_line_start): Don't use the shortcut if
16329 (back_to_previous_visible_line_start): If handle_display_prop
16330 pushed the iterator stack, restore the internal state of the bidi
16331 iterator by calling bidi_pop_it same number of times.
16332 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16333 and we are bidi-iterating, don't decrement the iterator position;
16334 instead, set the first_elt flag in the bidi iterator, to produce
16336 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16337 (push_display_prop): xassert that we are iterating a buffer.
16338 (push_it, pop_it): Save and restore paragraph_embedding member.
16339 (handle_single_display_spec, next_overlay_string)
16340 (get_overlay_strings_1, reseat_1, reseat_to_string)
16341 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16342 correctly. Don't assume unibyte strings are not bidi-reordered.
16343 (compute_display_string_pos)
16344 (compute_display_string_end): Fix handling the case of C string.
16345 (push_it, pop_it): Save and restore from_disp_prop_p.

16351 property. Fix a typo in popping stretch info. Add an assertion
16352 for verifying that the iterator position is in sync with the bidi
16354 (handle_single_display_spec, get_overlay_strings_1)

16379 displayed in margins. (Bug#8133) (Bug#8867)
16380 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16382 (pos_visible_p): Support positions in bidi-reordered lines.
16383 Save and restore bidi cache.
16385 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16386 (bidi_paragraph_info): Delete unused struct.

16404 Support iteration over a string.
16405 (bidi_set_sor_type, bidi_resolve_explicit_1)
16406 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit

16408 changed to -1 and -2, respectively.
16409 (bidi_char_at_pos): New function.
16410 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16498 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16499 The old code sometimes used this field without initializing it.
16501 * alloc.c (gc_sweep): Don't read past end of array.
16502 In theory, the old code could also have corrupted Emacs internals,
16503 though it'd be very unlikely.

16766 (clone_per_buffer_values): Don't assume that

16768 This isn't true in general, and it's particularly not true
16769 if Emacs is configured with --with-wide-int.
16770 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16771 New macros, used in the buffer.c change.

16807 Random fixes. E.g., (random) never returned negative values.
16808 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16809 subseconds part to the entropy, as that's a bit more random.
16810 Prefer signed to unsigned, since the signedness doesn't matter and
16811 in general we prefer signed. When given a limit, use a
16812 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16813 latter isn't right if USE_2_TAGS_FOR_INTS.
16814 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16815 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16827 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16828 This is more efficient than Ffile_directory_p and avoids a minor race.
16830 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16832 * buffer.c (Foverlay_put): Say what the return value is
16835 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16836 is a directory before asking whether to use the file name

16839 error be more correct.
16841 * fns.c (Frequire): Remove the mention of the .gz files, since
16842 that's installation-specific, but keep the mention of

16855 Qgnutls_bootprop_verify_error (which is no longer used).
16857 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16858 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16859 Also (re)move comments that are misplaced or no longer relevant.

16888 * lread.c (syms_of_lread): Mention single symbols defined by
16889 `defvar' or `defconst' (bug#7154).
16891 * fns.c (Frequire): Mention .el.gz files (bug#7314).
16892 (Frequire): Mention get-load-suffixes.

16926 2011-07-01 Glenn Morris <rgm@gnu.org>
16928 * Makefile.in (SETTINGS_LIBS): Fix typo.
16930 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)

16960 * eval.c (struct backtrace): Simplify and port the data structure.
16961 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16962 signed bit field, as this assumption is not portable and it makes
16963 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16964 "char debug_on_exit : 1" as this is not portable either; instead,
16965 use the portable "unsigned int debug_on_exit : 1". Remove unused
16966 member evalargs. Remove obsolete comments about cc bombing out.
16968 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
16970 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

17036 (emacs_fixed_new): Set priv->f to argument.
17037 (emacs_fixed_get_preferred_width)
17038 (emacs_fixed_get_preferred_height): Use min_width/height from
17039 frames size_hint to set minimum and natural (Bug#8919).
17040 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17041 and use min_width/height from frames size_hint to set
17042 min_width/height (Bug#8919).
17044 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

17062 Use gnulib's dup2 module instead of rolling our own.
17063 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17130 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17132 Integer and buffer overflow fixes (Bug#8873).
17134 * print.c (printchar, strout): Check for string overflow.
17135 (PRINTPREPARE, printchar, strout):
17136 Don't set size unless allocation succeeds.
17138 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17139 for sizes. Check for string overflow more accurately.
17140 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17142 * macros.c: Integer and buffer overflow fixes.
17143 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17144 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17147 Check for size-calculation overflow.
17148 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17150 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17152 * lread.c: Integer overflow fixes.
17153 (read_integer): Radix is now EMACS_INT, not int,
17154 to improve quality of diagnostics for out-of-range radices.
17155 Calculate buffer size correctly for out-of-range radices.
17156 (read1): Check for integer overflow in radices, and in
17157 read-circle numbers.
17158 (read_escape): Avoid int overflow.
17159 (Fload, openp, read_buffer_size, read1)
17160 (substitute_object_recurse, read_vector, read_list, map_obarray):
17161 Use ptrdiff_t, not int, for sizes.
17162 (read1): Use EMACS_INT, not int, for sizes.
17163 Check for size overflow.
17165 * image.c (cache_image): Check for size arithmetic overflow.

17176 2011-06-22 Leo Liu <sdl.web@gmail.com>
17178 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17179 Move to minibuffer.el.
17181 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17183 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17184 The following patches are for when GLYPH_DEBUG && !XASSERT.
17185 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17186 * dispnew.c (flush_stdout):
17187 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17188 Mark as externally visible.
17189 * dispnew.c (check_window_matrix_pointers): Now static.
17190 * dispnew.c (window_to_frame_vpos):
17191 * xfns.c (unwind_create_frame):
17192 * xterm.c (x_check_font): Remove unused local.
17193 * scroll.c (CHECK_BOUNDS):
17194 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17195 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17196 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17197 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17198 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17200 (debug_method_add): Use va_list and vsprintf rather than relying
17201 on undefined behavior with wrong number of arguments.
17202 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17203 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17204 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17205 since we're not interested in debugging glyphs with old libraries.
17206 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17207 GCC 4.6.0's static checking.
17209 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17211 Integer overflow and signedness fixes (Bug#8873).
17212 A few related buffer overrun fixes, too.

17220 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17221 (x_create_bitmap_from_xpm_data):
17222 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17223 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17225 * xfaces.c (load_pixmap):
17226 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17227 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17228 (.bitmaps_last, struct x_output.icon_bitmap):
17229 Use ptrdiff_t, not int, for bitmap indexes.
17230 (x_allocate_bitmap_record): Check for size overflow.
17231 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17233 Use ptrdiff_t, not int, for overlay counts.
17234 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17235 * editfns.c (overlays_around, get_pos_property):
17236 * textprop.c (get_char_property_and_overlay):
17237 * xdisp.c (next_overlay_change, note_mouse_highlight):
17238 * xfaces.c (face_at_buffer_position):
17239 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17240 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17241 (Fnext_overlay_change, Fprevious_overlay_change)
17242 (mouse_face_overlay_overlaps, Foverlays_in):
17243 Use ptrdiff_t, not int, for sizes.
17244 (overlays_at, overlays_in): Check for size-calculation overflow.
17246 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17248 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17249 (x_session_initialize): Do not assume string length fits in int.
17251 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17252 This is unlikely, but can occur if DPI is outlandish.
17254 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17255 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17257 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17258 * xrdb.c (magic_file_p, search_magic_path):
17259 Omit last arg SUFFIX; it was always 0. All callers changed.
17260 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17262 * xfont.c (xfont_match): Avoid need for strlen.
17264 * xfns.c: Don't assume strlen fits in int.
17265 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17267 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17268 not unsigned long, as we prefer signed integers. All callers changed.
17269 Detect integer overflow in repeat count.
17270 (message_dolog): Don't assume print length fits in 39 bytes.
17271 (display_mode_element): Don't assume strlen fits in int.
17273 * termcap.c: Don't assume sizes fit in int and never overflow.
17274 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17275 (gobble_line): Check for size-calculation overflow.
17277 * minibuf.c (Fread_buffer):
17278 * lread.c (intern, intern_c_string):
17279 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17280 Don't assume string length fits in int.
17282 * keyboard.c (parse_tool_bar_item):
17283 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17285 * font.c: Don't assume string length fits in int.
17286 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17287 Use ptrdiff_t, not int.
17288 (font_intern_prop): Don't assume string length fits in int.
17289 Don't assume integer property fits in fixnum.
17290 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17292 * filelock.c: Fix some buffer overrun and integer overflow issues.
17293 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17294 Reformulate so as not to need the command string.
17295 Invoke gzip -cd rather than gunzip, as it's more portable.
17296 (lock_info_type, lock_file_1, lock_file):
17297 Don't assume pid_t and time_t fit in unsigned long.
17298 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17299 (current_lock_owner): Prefer signed type for sizes.
17300 Use memcpy, not strncpy, where memcpy is what is really wanted.
17301 Don't assume (via atoi) that time_t and pid_t fit in int.
17302 Check for time_t and/or pid_t out of range, e.g., via a network share.
17303 Don't alloca where an auto var works fine.
17305 * fileio.c: Fix some integer overflow issues.
17306 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17307 Don't assume string length fits in int.
17308 (directory_file_name): Don't assume string length fits in long.
17309 (make_temp_name): Don't assume pid fits in int, or that its print
17310 length is less than 20.
17312 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17314 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17316 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17318 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17319 We prefer signed integers, even for size calculations.
17321 * emacs.c: Don't assume string length fits in 'int'.
17322 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17323 (main): Don't invoke strlen when not needed.
17325 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17326 (XD_DEBUG_MESSAGE): Don't waste a byte.
17328 * callproc.c (getenv_internal_1, getenv_internal)
17329 (Fgetenv_internal):
17330 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17332 * lread.c (invalid_syntax): Omit length argument.
17333 All uses changed. This doesn't fix a bug, but it simplifies the
17334 code away from its former Hollerith-constant appearance, and it's
17335 one less 'int' to worry about when looking at integer-overflow issues.
17336 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17338 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17339 This didn't break anything, but it didn't help either.
17340 It's confusing to put a bogus integer in a place where the actual
17341 value does not matter.
17342 (LIST_END_P): Remove unused macro and its bogus comment.
17343 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17345 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17346 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17348 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17349 We prefer signed types, and the value cannot exceed the EMACS_INT
17350 range anyway (because otherwise the length would not be representable).
17351 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17352 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17353 This avoids a GCC warning when WIDE_EMACS_INT.
17355 * indent.c (sane_tab_width): New function.
17356 (current_column, scan_for_column, Findent_to, position_indentation)
17357 (compute_motion): Use it. This is just for clarity.
17358 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17360 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17362 * lisp.h (lint_assume): New macro.
17363 * composite.c (composition_gstring_put_cache):
17364 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17366 * editfns.c, insdel.c:
17367 Omit unnecessary forward decls, to simplify future changes.
17369 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17371 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17373 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17374 Use much-faster test for byte-length change.
17375 Don't assume string byte-length fits in 'int'.
17376 Check that character arg fits in 'int'.
17377 (mapcar1): Declare byte as byte, for clarity.
17379 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17381 * fns.c (concat): Catch string overflow earlier.
17382 Do not rely on integer wraparound.
17384 * dispextern.h (struct it.overlay_strings_charpos)
17385 (struct it.selective): Now EMACS_INT, not int.
17386 * xdisp.c (forward_to_next_line_start)
17387 (back_to_previous_visible_line_start)
17388 (reseat_at_next_visible_line_start, next_element_from_buffer):
17389 Don't arbitrarily truncate the value of 'selective' to int.
17391 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17393 * composite.c: Don't truncate sizes to 'int'.
17394 (composition_gstring_p, composition_reseat_it)
17395 (composition_adjust_point): Use EMACS_INT, not int.
17396 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17397 not EMACS_UINT, for indexes.
17399 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17401 * buffer.c: Include <verify.h>.
17402 (struct sortvec.priority, struct sortstr.priority):
17403 Now EMACS_INT, not int.
17404 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17405 (struct sortstr.size, record_overlay_string)
17406 (struct sortstrlist.size, struct sortlist.used):
17407 Don't truncate size to int.
17408 (record_overlay_string): Check for size-calculation overflow.
17409 (init_buffer_once): Check at compile-time, not run-time.
17411 2011-06-22 Jim Meyering <meyering@redhat.com>
17413 Don't leak an XBM-image-sized buffer
17414 * image.c (xbm_load): Free the image buffer after using it.
17416 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17419 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17420 that Sun C diagnosed.
17421 * fns.c (secure_hash): Fix pointer signedness issue.
17422 * intervals.c (static_offset_intervals): New function.
17423 (offset_intervals): Use it.
17425 2011-06-21 Leo Liu <sdl.web@gmail.com>
17428 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17431 * fns.c (secure_hash): Rename from crypto_hash_function and change
17432 the first arg to accept symbols.
17433 (Fsecure_hash): New primitive.
17434 (syms_of_fns): New symbols.
17436 2011-06-20 Deniz Dogan <deniz@dogan.se>
17438 * process.c (Fset_process_buffer): Clarify return value in
17441 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17443 * dispnew.c (add_window_display_history): Use BVAR.
17445 * xdisp.c (debug_method_add): Use BVAR.
17446 (check_window_end, dump_glyph_matrix, dump_glyph)
17447 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17449 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17452 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17453 check till after the cache is created in init_frame_faces.
17455 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17457 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17459 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17461 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17462 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17463 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17465 Improve buffer-overflow checking (Bug#8873).
17466 * fileio.c (Finsert_file_contents):
17467 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17468 Remove the old (too-loose) buffer overflow checks.
17469 They weren't needed, since make_gap checks for buffer overflow.
17470 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17471 The old code merely checked for Emacs fixnum overflow, and relied
17472 on undefined (wraparound) behavior. The new code avoids undefined
17473 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17475 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17476 Tune. Don't use wider integers than needed. Don't use alloca.
17477 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17479 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17481 * insdel.c, lisp.h (buffer_overflow): New function.
17482 (insert_from_buffer_1, replace_range, replace_range_2):
17483 * insdel.c (make_gap_larger):
17484 * editfns.c (Finsert_char):
17485 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17487 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17489 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17491 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17493 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17494 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17496 * fileio.c: Don't assume EMACS_INT fits in off_t.
17497 (emacs_lseek): New static function.
17498 (Finsert_file_contents, Fwrite_region): Use it.
17499 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17501 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17503 * fns.c: Don't overflow int when computing a list length.
17504 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17505 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17506 truncation on 64-bit hosts. Check for QUIT every
17507 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17508 faster and is responsive enough.
17509 (Flength): Report an error instead of overflowing an integer.
17510 (Fsafe_length): Return a float if the value is not representable
17511 as a fixnum. This shouldn't happen except in contrived situations.
17512 (Fnthcdr, Fsort): Don't assume list length fits in int.
17513 (Fcopy_sequence): Don't assume vector length fits in int.
17515 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17516 (header_size, word_size): New constants.
17517 (allocate_vectorlike): Don't check size overflow here.
17518 (allocate_vector): Check it here instead, since this is the only
17519 caller of allocate_vectorlike that could cause overflow.
17520 Check that the new vector's length is representable as a fixnum.
17522 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17523 The previous code was bogus. For example, next_almost_prime (32)
17524 returned 39, which is undesirable as it is a multiple of 3; and
17525 next_almost_prime (24) returned 25, which is a multiple of 5 so
17526 why was the code bothering to check for multiples of 7?
17528 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17530 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17532 Variadic C functions now count arguments with ptrdiff_t.
17533 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17534 Back then I didn't know that the Emacs coding style prefers signed int.
17535 Also, in the meantime I found a few more instances where arguments
17536 were being counted with int, which may truncate counts on 64-bit
17537 machines, or EMACS_INT, which may be unnecessarily wide.
17538 * lisp.h (struct Lisp_Subr.function.aMANY)
17539 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17540 Arg counts are now ptrdiff_t, not size_t.
17541 All variadic functions and their callers changed accordingly.
17542 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17543 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17544 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17545 * callint.c (Fcall_interactively): Check arg count for overflow,
17546 to avoid potential buffer overrun. Use signed char, not 'int',
17547 for 'varies' array, so that we needn't bother to check its size
17548 calculation for overflow.
17549 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17550 * eval.c (apply_lambda):
17551 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17552 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17553 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17555 * callint.c (Fcall_interactively): Don't use index var as event count.
17557 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17558 * mem-limits.h (SIZE): Remove; no longer used.
17560 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17562 Remove unnecessary casts.
17563 * xterm.c (x_term_init):
17564 * xfns.c (x_set_border_pixel):
17565 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17566 These aren't needed now that we assume ANSI C.
17568 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17569 It's more likely to cause problems (due to unsigned overflow)
17572 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17574 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17576 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17578 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17580 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17582 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17584 GLYPH_CODE_FACE returns EMACS_INT, not int.
17585 * dispextern.h (merge_faces):
17586 * xfaces.c (merge_faces):
17587 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17588 Don't assume EMACS_INT fits in int.
17590 * character.h (CHAR_VALID_P): Remove unused parameter.
17591 * fontset.c, lisp.h, xdisp.c: All uses changed.
17593 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17595 * fns.c (concat): Minor tuning based on overflow analysis.
17596 This doesn't fix any bugs. Use int to hold character, instead
17597 of constantly refetching from Emacs object. Use XFASTINT, not
17598 XINT, for value known to be a character. Don't bother comparing
17599 a single byte to 0400, as it's always less.
17601 * floatfns.c (Fexpt):
17602 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17604 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17607 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17609 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17610 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17611 incorrectly succeed when S was a string, because 4294967386 was
17612 truncated before it was used.
17614 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17615 Otherwise, an out-of-range integer could cause undefined behavior
17618 * composite.c: Use int, not EMACS_INT, for characters.
17619 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17620 EMACS_INT, for values that are known to be in character range.
17621 This doesn't fix any bugs but is the usual style inside Emacs and
17622 may generate better code on 32-bit machines.
17624 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17625 This is for reasons similar to the recent CHAR_STRING fix.
17626 * charset.c (Fencode_char): Check that character arg is actually
17627 a character. Pass an int to ENCODE_CHAR.
17628 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17629 wider than 'int', as a compile-time check to prevent future regressions
17632 * character.c (char_string): Remove unnecessary casts.
17634 Make sure a 64-bit char is never passed to CHAR_STRING.
17635 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17636 by silently ignoring the top 32 bits, allowing some values
17637 that were far too large to be valid characters.
17638 * character.h: Include <verify.h>.
17639 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17640 arguments are no wider than unsigned, as a compile-time check
17641 to prevent future regressions in this area.
17643 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17644 (Fsubst_char_in_region):
17646 * xdisp.c (decode_mode_spec_coding):
17647 Adjust to CHAR_STRING's new requirement.
17648 * editfns.c (Finsert_char, Fsubst_char_in_region):
17649 * fns.c (concat): Check that character args are actually
17650 characters. Without this test, these functions did the wrong
17651 thing with wildly out-of-range values on 64-bit hosts.
17653 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17654 These casts should not be needed on 32-bit hosts, either.
17655 * keyboard.c (read_char):
17656 * lread.c (Fload): Remove casts to unsigned.
17658 * lisp.h (UNSIGNED_CMP): New macro.
17659 This fixes comparison bugs on 64-bit hosts.
17660 (ASCII_CHAR_P): Use it.
17661 * casefiddle.c (casify_object):
17662 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17663 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17664 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17665 * dispextern.h (FACE_FROM_ID):
17666 * keyboard.c (read_char): Use UNSIGNED_CMP.
17668 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17669 not to EMACS_INT, to avoid GCC warning.
17671 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17673 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17674 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17675 isn't needed on 32-bit machines.
17677 * buffer.c (Fgenerate_new_buffer_name):
17678 Use EMACS_INT for count, not int.
17679 (advance_to_char_boundary): Return EMACS_INT, not int.
17681 * data.c (Qcompiled_function): Now static.
17683 * window.c (window_body_lines): Now static.
17685 * image.c (gif_load): Rename local to avoid shadowing.
17687 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17688 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17689 * alloc.c (make_save_value): Integer argument is now of type
17690 ptrdiff_t, not int.
17691 (mark_object): Use ptrdiff_t, not int.
17692 * lisp.h (pD): New macro.
17693 * print.c (print_object): Use it.
17695 * alloc.c: Use EMACS_INT, not int, to count objects.
17696 (total_conses, total_markers, total_symbols, total_vector_size)
17697 (total_free_conses, total_free_markers, total_free_symbols)
17698 (total_free_floats, total_floats, total_free_intervals)
17699 (total_intervals, total_strings, total_free_strings):
17700 Now EMACS_INT, not int. All uses changed.
17701 (Fgarbage_collect): Compute overall total using a double, so that
17702 integer overflow is less likely to be a problem. Check for overflow
17703 when converting back to an integer.
17704 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17705 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17706 These were 'int' variables that could overflow on 64-bit hosts;
17707 they were never used, so remove them instead of repairing them.
17708 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17709 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17710 Previously, this ceilinged at INT_MAX, but that doesn't work on
17712 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17714 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17715 (allocate_vectorlike): Check for ptrdiff_t overflow.
17716 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17717 when a (possibly-narrower) signed value would do just as well.
17718 We prefer using signed arithmetic, to avoid comparison confusion.
17720 * alloc.c: Catch some string size overflows that we were missing.
17721 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17722 for convenience in STRING_BYTES_MAX.
17723 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17724 The definition here is exact; the one in lisp.h was approximate.
17725 (allocate_string_data): Check for string overflow. This catches
17726 some instances we weren't catching before. Also, it catches
17727 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17728 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17729 and ptrdiff_t and EMACS_INT are both 64 bits.
17731 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17732 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17733 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17735 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17737 * alloc.c (Fmake_string): Check for out-of-range init.
17739 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17741 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17743 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17745 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17746 xg_get_default_scrollbar_width.
17748 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17749 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17750 (style_changed_cb): Call update_theme_scrollbar_width and call
17751 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17752 all frames (Bug#8505).
17753 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17754 Call gtk_window_set_resizable if HAVE_GTK3.
17755 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17756 and height if HAVE_GTK3 (Bug#8505).
17757 (scroll_bar_width_for_theme): New variable.
17758 (update_theme_scrollbar_width): New function.
17759 (xg_get_default_scrollbar_width): Move code to
17760 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17761 (xg_initialize): Call update_theme_scrollbar_width.
17763 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17765 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17767 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17769 * frame.c (make_frame): Call other_buffer_safely instead of
17772 * window.c (temp_output_buffer_show): Call display_buffer with
17773 second argument Vtemp_buffer_show_specifiers and reset latter
17774 immediately after the call.
17775 (Vtemp_buffer_show_specifiers): New variable.
17776 (auto_window_vscroll_p, next_screen_context_lines)
17777 (Vscroll_preserve_screen_position): Remove leading asterisks from
17780 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17782 Fix minor problems found by GCC 4.6.0 static checking.
17783 * buffer.c (Qclone_number): Remove for now, as it's unused.
17784 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17785 (record_buffer): Remove unused local.
17786 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17787 (set_frame_buffer_list): Remove; unused.
17788 * frame.h (other_visible_frames): Remove decl.
17789 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
17790 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
17791 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
17793 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
17794 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):

18271 New error handlers.
18272 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
18273 Obey Vx_select_enable_clipboard_manager. Catch errors in
18274 x_clipboard_manager_save (Bug#8779).
18275 (Vx_select_enable_clipboard_manager): New variable.
18276 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18278 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18280 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18282 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18284 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18285 in the current matrix if keep_current_p is non-zero.

18289 * bidi.c (bidi_level_of_next_char): Fix last change.
18291 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18293 Support bidi reordering of text covered by display properties.
18295 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18296 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18297 (bidi_cache_search, bidi_cache_iterator_state)
18298 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18299 (bidi_level_of_next_char, bidi_move_to_visually_next):
18300 Support character positions inside a run of characters covered by a
18302 (bidi_paragraph_init, bidi_resolve_explicit_1)
18303 (bidi_level_of_next_char): Call bidi_fetch_char and
18304 bidi_fetch_char_advance instead of FETCH_CHAR and
18305 FETCH_CHAR_ADVANCE.

18307 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18309 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18310 instead of using explicit *_CHAR codes.
18311 (bidi_resolve_explicit, bidi_resolve_weak):
18312 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18313 bidirectional text is supported only in multibyte buffers.
18314 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18315 it to initialize the frame_window_p member of struct bidi_it.
18316 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18317 (bidi_resolve_explicit, bidi_resolve_weak)

18319 bidi_it->nchars is non-positive.
18320 (bidi_level_of_next_char): Don't try to lookup the cache for the
18321 next/previous character if nothing is cached there yet, or if we
18322 were just reseat()'ed to a new position.
18324 * xdisp.c (set_cursor_from_row): Set start and stop points
18325 according to the row's direction when priming the loop that looks
18326 for the glyph on which to display cursor.
18327 (single_display_spec_intangible_p): Function deleted.
18328 (display_prop_intangible_p): Reimplement to call
18329 handle_display_spec instead of single_display_spec_intangible_p.
18330 Accept 3 additional arguments needed by handle_display_spec.
18331 This fixes incorrect cursor motion across display property with complex
18332 values: lists, `(when COND...)' forms, etc.
18333 (single_display_spec_string_p): Support property values that are
18334 lists with the argument STRING its top-level element.
18335 (display_prop_string_p): Fix the condition for processing a
18336 property that is a list to be consistent with handle_display_spec.
18337 (handle_display_spec): New function, refactored from the
18338 last portion of handle_display_prop.
18339 (compute_display_string_pos): Accept additional argument
18340 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18341 value of a `display' property is a "replacing spec".
18342 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18343 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18344 the display property, but just return a value indicating whether
18345 the display property will replace the characters it covers.
18346 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18347 frame_window_p members of struct bidi_it.
18348 (compute_display_string_pos, compute_display_string_end):
18350 (push_it): Accept second argument POSITION, where pop_it should
18351 jump to continue iteration.
18352 (reseat_1): Initialize bidi_it.disp_pos.
18354 * keyboard.c (adjust_point_for_property): Adjust the call to
18355 display_prop_intangible_p to its new signature.
18357 * dispextern.h (struct bidi_it): New member frame_window_p.
18358 (bidi_init_it): Update prototypes.
18359 (display_prop_intangible_p): Update prototype.
18360 (compute_display_string_pos, compute_display_string_end):
18361 Declare prototypes.
18362 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18365 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18367 Malloc failure behavior now depends on size of allocation.
18368 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18369 * lisp.h: Change signatures accordingly.
18370 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18371 All callers changed. (Bug#8762)
18373 * gnutls.c: Use Emacs's memory allocators.
18374 Without this change, the gnutls library would invoke malloc etc.
18375 directly, which causes problems on non-SYNC_INPUT hosts, and which
18376 runs afoul of improving memory_full behavior. (Bug#8761)
18377 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18378 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18379 xfree instead of the default malloc, realloc, free.
18380 (Fgnutls_boot): No need to check for memory allocation failure,
18381 since xmalloc does that for us.
18383 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18384 * category.c (hash_get_category_set):
18385 * ccl.c (ccl_driver):
18386 * charset.c (Fdefine_charset_internal):

18397 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18398 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18399 * image.c (make_image, search_image_cache, lookup_image)
18400 (xpm_put_color_table_h):
18401 * lisp.h (struct Lisp_Hash_Table):
18402 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18403 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18404 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18405 * alloc.c (allocate_vectorlike):
18406 Check for overflow in vector size calculations.
18407 * ccl.c (ccl_driver):
18408 Check for overflow when converting EMACS_INT to int.
18409 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18410 need to be updated by these changes.
18411 * fns.c (make_hash_table, maybe_resize_hash_table):
18412 Check for integer overflow with large hash tables.
18413 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18414 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18415 (SXHASH_REDUCE): New macro.
18416 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18417 Use it instead of discarding useful hash info with large hash values.
18418 (sxhash_float): New function.
18419 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18420 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18421 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18422 Rewrite to use FIXNUM_BITS, as this simplifies things.
18423 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18424 Adjust signatures to match updated version of code.
18425 (consing_since_gc): Now EMACS_INT, since a single hash table can
18426 use more than INT_MAX bytes.
18428 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18430 Make it possible to build with GCC-4.6+ -O2 -flto.
18432 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18434 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18436 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18437 Call minibuffer-inactive-mode.
18439 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18441 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18442 Update dependencies.
18444 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18446 * data.c (init_data): Remove code for UTS, this system is not
18449 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18451 Don't force ./temacs to start in terminal mode.
18453 * frame.c (make_initial_frame): Initialize faces in all cases, not
18454 only when CANNOT_DUMP is defined.
18455 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18457 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18459 * dispnew.c (add_window_display_history): Use const for the string
18460 pointer. Remove declaration, not needed.
18462 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18464 Use 'inline', not 'INLINE'.
18465 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18466 * alloc.c, fontset.c (INLINE): Remove.
18467 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18468 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18469 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18470 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18471 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18473 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18475 Make it possible to run ./temacs.
18477 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18478 syms_of_callproc does the same thing. Remove test for
18479 "initialized", do it in the caller.
18480 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18482 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18484 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18485 (read_minibuf): Use get_minibuffer.
18486 (syms_of_minibuf): Use DEFSYM.
18487 (Qmetadata): New var.
18488 * data.c (Qbuffer): Don't make it static.
18489 (syms_of_data): Use DEFSYM.
18491 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18493 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18494 (CCL_CODE_MIN): New macro.
18496 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18498 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18500 * eval.c (Qdebug): Now static.
18501 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18502 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18503 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18505 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18507 * image.c: Various fixes to ImageMagick code comments.
18508 (Fimagemagick_types): Doc fix.
18510 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18512 Minor fixes prompted by GCC 4.6.0 warnings.
18514 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18516 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18517 (x_clipboard_manager_save_all): Move extern decl to ...
18518 * xterm.h: ... here, so that it can be checked for consistency.
18520 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18522 * xselect.c (x_clipboard_manager_save_frame)
18523 (x_clipboard_manager_save_all): New functions.
18524 (Fx_clipboard_manager_save): Lisp function deleted.
18526 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18527 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18529 * xterm.h: Update prototype.
18531 2011-05-28 William Xu <william.xwl@gmail.com>
18533 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18534 exiting (Bug#8239).
18536 2011-05-28 Jim Meyering <meyering@redhat.com>
18538 Avoid a sign-extension bug in crypto_hash_function.
18539 * fns.c (to_uchar): Define.
18540 (crypto_hash_function): Use it to convert some newly-signed
18541 variables to unsigned, to avoid sign-extension bugs. For example,
18542 without this change, (md5 "truc") would evaluate to
18543 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18544 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18545 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18547 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18549 Integer overflow fixes.
18551 * dbusbind.c: Serial number integer overflow fixes.
18552 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18553 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18554 to hold a serial number that is too large for a fixnum.
18555 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18556 Check for serial numbers out of range. Decode any serial number
18557 that was so large that it became a float. (Bug#8722)
18559 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18560 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18561 Use XFASTINT rather than XUINT when numbers are nonnegative.
18562 (xd_append_arg, Fdbus_method_return_internal):
18563 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18564 arguments, check that Lisp number is nonnegative, rather than
18565 silently wrapping negative numbers around. (Bug#8722)
18566 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18569 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18571 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18573 ccl: Add integer overflow checks.
18574 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18575 (IN_INT_RANGE): New macros.
18576 (ccl_driver): Use them to check for integer overflow when
18577 decoding a CCL program. Many of the new checks are whether XINT (x)
18578 fits in int; it doesn't always, on 64-bit hosts. The new version
18579 doesn't catch all possible integer overflows, but it's an
18580 improvement. (Bug#8719)
18582 * alloc.c (make_event_array): Use XINT, not XUINT.
18583 There's no need for unsigned here.
18585 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18586 This follows up to the 2011-05-06 change that substituted uintptr_t
18587 for EMACS_INT. This case wasn't caught back then.
18589 Rework Fformat to avoid integer overflow issues.
18590 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18591 now (part of C89). Include <verify.h>.
18592 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18593 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18594 (Fformat): Avoid the prepass trying to compute sizes; it was only
18595 approximate and thus did not catch overflow reliably. Instead, walk
18596 through the format just once, formatting and computing sizes as we go,
18597 checking for integer overflow at every step, and allocating a larger
18598 buffer as needed. Keep track separately whether the format is
18599 multibyte. Keep only the most-recently calculated precision, rather
18600 than them all. Record whether each argument has been converted to
18601 string. Use EMACS_INT, not int, for byte and char and arg counts.
18602 Support field widths and precisions larger than INT_MAX. Avoid
18603 sprintf's undefined behavior with conversion specifications such as %#d
18604 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18605 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18606 formatting out-of-range floating point numbers with int
18607 formats. (Bug#8668)
18609 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18611 * data.c: Avoid integer truncation in expressions involving floats.
18612 * data.c: Include <intprops.h>.
18613 (arith_driver): When there's an integer overflow in an expression
18614 involving floating point, convert the integers to floating point
18615 so that the resulting value does not suffer from catastrophic
18616 integer truncation. For example, on a 64-bit host (* 4
18617 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18618 Do not rely on undefined behavior after integer overflow.
18620 merge count_size_as_multibyte, parse_str_to_multibyte
18621 * character.c, character.h (count_size_as_multibyte):
18622 Rename from parse_str_to_multibyte; all uses changed.
18623 Check for integer overflow.
18624 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18625 since it's now a duplicate of the other. This is more of
18626 a character than a buffer op, so better that it's in character.c.
18627 * fns.c, print.c: Adjust to above changes.
18629 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18631 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18633 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18635 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18636 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18637 (x_clipboard_manager_save): Now static.
18638 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18640 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18641 (crypto_hash_function): Now static.
18642 Fix pointer signedness problems. Avoid unnecessary initializations.
18644 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18646 * termhooks.h (Vselection_alist): Make it terminal-local.
18648 * terminal.c (create_terminal): Initialize it.
18650 * xselect.c: Support for clipboard managers.
18651 (Vselection_alist): Move to termhooks.h as terminal-local var.
18652 (LOCAL_SELECTION): New macro.
18653 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18654 (symbol_to_x_atom): Remove gratuitous arg.
18655 (x_handle_selection_request, lisp_data_to_selection_data)
18656 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18657 (x_own_selection, x_get_local_selection, x_convert_selection):
18658 New arg, specifying work frame. Use terminal-local Vselection_alist.
18659 (some_frame_on_display): Delete unused function.
18660 (Fx_own_selection_internal, Fx_get_selection_internal)
18661 (Fx_disown_selection_internal, Fx_selection_owner_p)
18662 (Fx_selection_exists_p): New optional frame arg.
18663 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18664 (x_handle_selection_clear): Don't treat other terminals with the
18665 same keyboard specially. Use the terminal-local Vselection_alist.
18666 (x_clear_frame_selections): Use Frun_hook_with_args.
18668 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18670 * xterm.h: Add support for those atoms.
18672 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18674 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18675 (converted_selections, conversion_fail_tag): New global variables.
18676 (x_selection_request_lisp_error): Free the above.
18677 (x_get_local_selection): Remove unnecessary code.
18678 (x_reply_selection_request): Args changed; handle arbitrary array
18679 of converted selections stored in converted_selections.
18680 Separate the XChangeProperty and SelectionNotify steps.
18681 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18682 (x_convert_selection): New function.
18683 (x_handle_selection_event): Simplify.
18684 (x_get_foreign_selection): Don't ignore incoming requests while
18685 waiting for an answer; this will fail when we implement
18686 SAVE_TARGETS, and seems unnecessary anyway.
18687 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18688 (Vx_sent_selection_functions): Doc fix.
18690 2011-05-26 Leo Liu <sdl.web@gmail.com>
18692 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18694 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18696 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18698 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18699 for fringe update if it has periodic bitmap.
18700 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18701 and fringe_bitmap_periodic_p.
18703 * fringe.c (get_fringe_bitmap_data): New function.
18704 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18705 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18706 row. Mark glyph row for fringe update if periodicity changed.
18708 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18709 for fringe update unless it has periodic bitmap.
18711 2011-05-25 Kenichi Handa <handa@m17n.org>
18713 * xdisp.c (get_next_display_element): Set correct it->face_id for
18714 a static composition.
18716 2011-05-24 Leo Liu <sdl.web@gmail.com>
18719 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18721 * fns.c (crypto_hash_function, Fsha1): New function.
18722 (Fmd5): Use crypto_hash_function.
18723 (syms_of_fns): Add Ssha1.
18725 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18727 * gnutls.c: Remove unused macros.
18728 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18729 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18730 Remove macros that are defined and never used.
18731 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18733 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18735 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18736 (Fx_get_selection_internal): Minor cleanup.
18737 (Fx_own_selection_internal): Rename arguments for consistency with
18740 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18742 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18744 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18746 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18748 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18750 * dispnew.c (scrolling_window): Don't exclude the case that the
18751 last enabled row in the desired matrix touches the bottom boundary.
18753 2011-05-21 Glenn Morris <rgm@gnu.org>
18755 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18756 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18757 and add some more files.
18759 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18761 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18762 report_file_error introduced by the change from 2011-05-07.
18764 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18766 * systime.h (Time): Define only if emacs is defined.
18767 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18768 where the include path doesn't have X11/X.h by default. See
18769 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18771 2011-05-20 Kenichi Handa <handa@m17n.org>
18773 * composite.c (find_automatic_composition): Fix previous change.
18775 2011-05-20 Glenn Morris <rgm@gnu.org>
18777 * lisp.mk: New file, split from Makefile.in.
18778 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18779 (shortlisp): Remove.
18780 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18782 2011-05-19 Glenn Morris <rgm@gnu.org>
18784 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18785 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18786 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18787 (lisp): Set the order to that of loadup.el.
18788 (shortlisp): Make it a copy of $lisp.
18789 (SOME_MACHINE_LISP): Remove.
18790 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18791 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18793 2011-05-18 Kenichi Handa <handa@m17n.org>
18795 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18796 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18797 (find_automatic_composition): Mostly rewrite for efficiency.
18799 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18801 * makefile.w32-in: Update dependencies.
18803 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18805 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18806 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18808 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18810 Fix some integer overflow issues, such as string length overflow.
18812 * insdel.c (count_size_as_multibyte): Check for string overflow.
18814 * character.c (lisp_string_width): Check for string overflow.
18815 Use EMACS_INT, not int, for string indexes and lengths; in
18816 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18817 the resulting string length overflows an EMACS_INT; instead,
18818 report a string overflow if no precision given. When checking for
18819 precision exhaustion, use a check that cannot possibly have
18820 integer overflow. (Bug#8675)
18821 * character.h (lisp_string_width): Adjust to new signature.
18823 * alloc.c (string_overflow): New function.
18824 (Fmake_string): Use it. This doesn't change behavior, but saves
18825 a few bytes and will simplify future changes.
18826 * character.c (string_escape_byte8): Likewise.
18827 * lisp.h (string_overflow): New decl.
18829 Fixups, following up to the user-interface timestamp change.
18830 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18831 for UI timestamps, instead of unsigned long.
18832 * msdos.c (mouse_get_pos): Likewise.
18833 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18834 * w32gui.h (Time): Define by including "systime.h" rather than by
18835 declaring it ourselves. (Bug#8664)
18837 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18838 * image.c (clear_image_cache): Likewise.
18840 * term.c (term_mouse_position): Don't assume time_t wraparound.
18842 Be more systematic about user-interface timestamps.
18843 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18844 and sometimes 'EMACS_UINT', to represent these timestamps.
18845 This change causes it to use 'Time' uniformly, as that's what X uses.
18846 This makes the code easier to follow, and makes it easier to catch
18847 integer overflow bugs such as Bug#8664.
18848 * frame.c (Fmouse_position, Fmouse_pixel_position):
18849 Use Time, not unsigned long, for user-interface timestamps.
18850 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18851 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18852 * keyboard.h (last_event_timestamp): Likewise.
18853 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18854 * menu.h (xmenu_show): Likewise.
18855 * term.c (term_mouse_position): Likewise.
18856 * termhooks.h (struct input_event.timestamp): Likewise.
18857 (struct terminal.mouse_position_hook): Likewise.
18858 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18859 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18860 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18861 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18862 what it was before.
18863 * menu.h, termhooks.h: Include "systime.h", for Time.
18865 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18866 Don't assume that the difference between two unsigned long values
18867 can fit into an integer. At this point, we know button_down_time
18868 <= event->timestamp, so the difference must be nonnegative, so
18869 there's no need to cast the result if double-click-time is
18870 nonnegative, as it should be; check that it's nonnegative, just in
18871 case. This bug is triggered when events are more than 2**31 ms
18872 apart (about 25 days). (Bug#8664)
18874 * xselect.c (last_event_timestamp): Remove duplicate decl.
18875 (x_own_selection): Remove needless cast to unsigned long.
18877 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18878 that always fit in int. Use a sentinel instead of a counter, to
18879 avoid a temp and to allay GCC's concerns about possible int overflow.
18880 * frame.h (struct frame): Use int for menu_bar_items_used
18881 instead of EMACS_INT, since it always fits in int.
18883 * menu.c (grow_menu_items): Check for int overflow.
18885 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18887 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18888 Before, the code was not consistent. These values cannot exceed
18889 2**31 - 1 so there's no need to make them unsigned.
18890 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18891 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18892 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18894 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18896 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18897 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18898 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18899 presumably because the widths might not match.
18901 * window.c (size_window): Avoid needless test at loop start.
18903 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18905 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18907 2011-05-12 Drew Adams <drew.adams@oracle.com>
18909 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18911 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18913 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18914 `width' to `bar_area_x' and `bar_area_width', respectively.
18915 (x_scroll_run): Take account of fringe background extension.
18917 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18918 Rename local vars `left' and `width' to `bar_area_x' and
18919 `bar_area_width', respectively.
18920 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18921 background extension.
18923 2011-05-10 Jim Meyering <meyering@redhat.com>
18925 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18927 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18929 * image.c (Finit_image_library): Return t for built-in image types,
18930 like pbm and xbm. (Bug#8640)
18932 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18934 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18936 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18938 * w32console.c (Fset_screen_color): Doc fix.
18939 (Fget_screen_color): New function.
18940 (syms_of_ntterm): Defsubr it.
18942 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18943 unlink the temporary file if Fcall_process didn't create it in the
18945 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18946 child process will be redirected to a file specified with `:file'.
18947 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18948 cue to call_process_cleanup not to close that handle.
18950 2011-05-07 Ben Key <bkey76@gmail.com>
18952 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18953 one of two shell specific rules, either bootstrap-temacs-CMD or
18954 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18955 to the previous implementation of the bootstrap-temacs rule.
18956 The bootstrap-temacs-CMD rule is similar to the previous
18957 implementation of the bootstrap-temacs rule except that it
18958 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18961 These changes, along with some changes to nt/configure.bat,
18962 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18963 earlier fix to add support for --cflags and --ldflags options
18964 that include quotes so that it works whether make uses cmd or
18967 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18969 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18970 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18972 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18973 a string. Handle both cases.
18974 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18975 (Fdbus_register_method): Use Qinvalid_function.
18977 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18979 * makefile.w32-in: Update dependencies.
18980 (LISP_H): Add inttypes.h and stdin.h.
18981 (PROCESS_H): Add unistd.h.
18983 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18985 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18986 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18988 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18990 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18992 * term.c (vfatal): Remove stray call to va_end.
18993 It's not needed and the C Standard doesn't allow it here anyway.
18995 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18996 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18998 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19001 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19003 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19005 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19007 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19009 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19011 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19012 * charset.c (Fdefine_charset_internal): Don't initialize
19013 charset.code_space[15]. The value was garbage, on hosts with
19014 32-bit int (Bug#8600).
19016 * lread.c (read_integer): Be more consistent with string-to-number.
19017 Use string_to_number to do the actual conversion; this avoids
19018 rounding errors and fixes some other screwups. Without this fix,
19019 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19020 (digit_to_number): Move earlier, for benefit of read_integer.
19021 Return -1 if the digit is out of range for the base, -2 if it is
19022 not a digit in any supported base. (Bug#8602)
19024 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19026 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19027 to match comment at start of function. This also removes a
19028 GCC warning about overflow in a 32+64-bit port.
19030 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19032 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19033 Reported by Stefan Monnier in
19034 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19035 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19036 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19038 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19039 (EMACS_UINTPTR): Likewise, with uintptr_t.
19041 * lisp.h: Prefer 64-bit EMACS_INT if available.
19042 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19043 on 32-bit hosts that have 64-bit int, so that they can access
19045 However, temporarily disable this change unless the temporary
19046 symbol WIDE_EMACS_INT is defined.
19048 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19050 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19051 This removes an assumption that EMACS_INT and long are the same
19052 width as pointers. The assumption is true for Emacs porting targets
19053 now, but we want to make other targets possible.
19054 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19055 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19056 In the rest of the code, change types of integers that hold casted
19057 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19058 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19059 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19060 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19061 No need to cast type when ORing.
19062 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19063 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19064 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19065 assume EMACS_INT is the same width as char *.
19066 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19067 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19068 Remove no-longer-needed casts.
19069 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19070 (xg_tool_bar_help_callback, xg_make_tool_item):
19071 Use EMACS_INTPTR to hold an integer
19072 that will be cast to void *; this can avoid a GCC warning
19073 if EMACS_INT is not the same width as void *.
19074 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19075 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19076 (current_message_1, set_message_1):
19077 Use a local to convert to proper width without a cast.
19078 * xmenu.c (dialog_selection_callback): Likewise.
19080 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19081 Also, don't assume VALBITS / RAND_BITS is less than 5,
19082 and don't rely on undefined behavior when shifting a 1 left into
19084 * lisp.h (get_random): Change signature to match.
19086 * lread.c (hash_string): Use size_t, not int, for hash computation.
19087 Normally we prefer signed values; but hashing is special, because
19088 it's better to use unsigned division on hash table sizes so that
19089 the remainder is nonnegative. Also, size_t is the natural width
19090 for hashing into memory. The previous code used 'int', which doesn't
19091 retain enough info to hash well into very large tables.
19092 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19094 * dbusbind.c: Don't possibly lose pointer info when converting.
19095 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19096 Use XPNTR rather than XHASH, so that the high-order bits of
19097 the pointer aren't lost when converting through void *.

19184 * process.c: Include lisp.h before w32.h, not after.
19185 (wait_reading_process_output): Call emacs_gnutls_record_check_pending

19190 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19192 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

19269 produced by %s or %c overflows available buffer space. (Bug#8545)
19271 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19273 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

19276 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19278 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19280 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19282 * keyboard.c (Qdelayed_warnings_hook): Define.
19283 (command_loop_1): Run `delayed-warnings-hook'
19284 if Vdelayed_warnings_list is non-nil.
19285 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19286 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19288 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19290 * doprnt.c (doprnt): Don't return value smaller than the buffer
19291 size if the message was truncated. (Bug#8545).
19293 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19295 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19296 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19298 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19300 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19302 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19304 * makefile.w32-in: Update dependencies.
19306 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19308 Improve `doprnt' and its usage. (Bug#8545)
19309 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19310 `format_end'. Remove support for %l as a conversion specifier.
19311 Don't use xrealloc. Improve diagnostics when the %l size modifier
19312 is used. Update the commentary.
19314 * eval.c (verror): Simplify calculation of size_t.
19316 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19319 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19321 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19324 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19326 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19327 This makes this file independent of the recent pseudovector change.
19329 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19331 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19333 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19334 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19335 Remove unused local.
19336 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19338 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19339 GCC 4.6.0 optimizes based on type-based alias analysis.
19340 For example, if b is of type struct buffer * and v of type struct
19341 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19342 != &v->size, and therefore "v->size = 1; b->size = 2; return
19343 v->size;" must therefore return 1. This assumption is incorrect
19344 for Emacs, since it type-puns struct Lisp_Vector * with many other
19345 types. To fix this problem, this patch adds a new type struct
19346 vectorlike_header that documents the constraints on layout of vectors
19347 and pseudovectors, and helps optimizing compilers not get fooled
19348 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19349 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19350 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19352 (XSETPVECTYPE): Rewrite in terms of new macro.
19353 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19354 This is a bit clearer, and further avoids the possibility of
19355 undesirable aliasing.
19356 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19357 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19358 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19359 since Lisp_Subr is a special case (no "next" field).
19360 (ASIZE): Now uses header.size rather than size.
19361 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19362 to avoid the hassle of writing XVECTOR (foo)->header.size.
19363 (struct vectorlike_header): New type.
19364 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19365 object, to help avoid aliasing.
19366 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19367 (SUBRP): Likewise, since Lisp_Subr is a special case.
19368 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19369 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19370 (struct Lisp_Hash_Table): Combine first two members into a single
19371 struct vectorlike_header member. All uses of "size" and "next" members
19372 changed to be "header.size" and "header.next".
19373 * buffer.h (struct buffer): Likewise.
19374 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19375 * frame.h (struct frame): Likewise.
19376 * process.h (struct Lisp_Process): Likewise.
19377 * termhooks.h (struct terminal): Likewise.
19378 * window.c (struct save_window_data, struct saved_window): Likewise.
19379 * window.h (struct window): Likewise.
19380 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19381 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19382 * buffer.c (init_buffer_once): Likewise.
19383 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19385 * process.c (Fformat_network_address): Use local var for size,
19388 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19390 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19391 * data.c (atof): Remove decl; no longer used or needed.
19392 (digit_to_number): Move to lread.c.
19393 (Fstring_to_number): Use new string_to_number function, to be
19394 consistent with how the Lisp reader treats infinities and NaNs.
19395 Do not assume that floating-point numbers represent EMACS_INT
19396 without losing information; this is not true on most 64-bit hosts.
19397 Avoid double-rounding errors, by insisting on integers when
19398 parsing non-base-10 numbers, as the documentation specifies.
19399 * lisp.h (string_to_number): New decl, replacing ...
19400 (isfloat_string): Remove.
19401 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19402 (read1): Do not accept +. and -. as integers; this
19403 appears to have been a coding error. Similarly, do not accept
19404 strings like +-1e0 as floating point numbers. Do not report
19405 overflow for integer overflows unless the base is not 10 which
19406 means we have no simple and reliable way to continue.
19407 Break out the floating-point parsing into a new
19408 function string_to_number, so that Fstring_to_number parses
19409 floating point numbers consistently with the Lisp reader.
19410 (digit_to_number): Move here from data.c. Make it static inline.
19411 (E_CHAR, EXP_INT): Remove, replacing with ...
19412 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19413 (string_to_number): New function, replacing isfloat_string.
19414 This function checks for valid syntax and produces the resulting
19415 Lisp float number too. Rework it so that string-to-number
19416 no longer mishandles examples like "1.0e+". Use strtoumax,
19417 so that overflow for non-base-10 numbers is reported only when
19418 there's no portable and simple way to convert to floating point.
19420 * textprop.c (set_text_properties_1): Rewrite for clarity,
19421 and to avoid GCC warning about integer overflow.
19423 * intervals.h (struct interval): Use EMACS_INT for members
19424 where EMACS_UINT might cause problems. See
19425 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19426 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19427 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19429 (offset_intervals): Tell GCC not to worry about length overflow
19430 when negating a negative length.
19432 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19433 (overrun_check_free): Likewise.
19435 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19436 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19439 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19440 (gnutls_make_error): Rename local to avoid shadowing.
19441 (gnutls_emacs_global_deinit): ifdef out; not used.
19442 (Fgnutls_boot): Use const for pointer to readonly storage.
19443 Comment out unused local. Fix pointer signedness problems.
19445 * lread.c (openp): Don't stuff size_t into an 'int'.
19446 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19447 about possible signed overflow.
19449 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19450 (GDK_KEY_g): Don't define if already defined.
19451 (xg_prepare_tooltip): Avoid pointer signedness problem.
19452 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19454 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19455 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19457 * xfns.c (Fx_window_property): Simplify a bit,
19458 to make a bit faster and to avoid GCC 4.6.0 warning.
19459 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19461 * fns.c (internal_equal): Don't assume size_t fits in int.
19463 * alloc.c (compact_small_strings): Tighten assertion a little.
19465 Replace pEd with more-general pI, and fix some printf arg casts.
19466 * lisp.h (pI): New macro, generalizing old pEd macro to other
19467 conversion specifiers. For example, use "...%"pI"d..." rather
19468 than "...%"pEd"...".
19469 (pEd): Remove. All uses replaced with similar uses of pI.
19470 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19471 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19472 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19473 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19474 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19475 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19476 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19478 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19479 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19480 * print.c (safe_debug_print, print_object): Likewise.
19481 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19483 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19484 avoiding the 0 flag, which is not portable.
19485 * process.c (Fmake_network_process): Use pI to avoid cast.
19486 * region-cache.c (pp_cache): Likewise.
19487 * xdisp.c (decode_mode_spec): Likewise.
19488 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19489 behavior on 64-bit hosts with printf arg.
19490 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19491 (x_stop_queuing_selection_requests): Likewise.
19492 (x_get_window_property): Don't truncate byte count to an 'int'
19495 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19496 here, since it parses constructs like leading '-' and spaces,
19497 which are not wanted; and it overflows with large numbers.
19498 Instead, simply match F[0-9]+, which is what is wanted anyway.
19500 * alloc.c: Remove unportable assumptions about struct layout.
19501 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19502 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19503 (allocate_vectorlike, make_pure_vector): Use the new macros,
19504 plus offsetof, to remove unportable assumptions about struct layout.
19505 These assumptions hold on all porting targets that I know of, but
19506 they are not guaranteed, they're easy to remove, and removing them
19507 makes further changes easier.
19509 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19510 This doesn't fix a bug but makes the code clearer.
19511 (string_overrun_cookie): Now const. Use initializers that
19512 don't formally overflow signed char, to avoid warnings.
19513 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19514 can cause Emacs to crash when string overrun checking is enabled.
19515 (allocate_buffer): Don't assume sizeof (struct buffer) is a

20410 * syntax.c (skip_chars): Likewise.
20412 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20413 This also lets GCC 4.6.0 generate slightly better loop code.
20415 * callint.c (Fcall_interactively): <, not <=, for optimization.
20416 (Fcall_interactively): Count the number of arguments produced,
20417 not the number of arguments given. This is simpler and lets GCC
20418 4.6.0 generate slightly better code.
20420 * ftfont.c: Distingish more carefully between FcChar8 and char.
20421 The previous code passed unsigned char * to a functions like
20422 strlen and xstrcasecmp that expect char *, which does not
20423 conform to the C standard.
20424 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20425 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20426 char * when the C standard requires it.
20428 * keyboard.c (read_char): Remove unused var.
20430 * eval.c: Port to Windows vsnprintf (Bug#8435).
20431 Include <limits.h>.
20432 (SIZE_MAX): Define if the headers do not.
20433 (verror): Do not give up if vsnprintf returns a negative count.
20434 Instead, grow the buffer. This ports to Windows vsnprintf, which
20435 does not conform to C99. Problem reported by Eli Zaretskii.
20436 Also, simplify the allocation scheme, by avoiding the need for
20437 calling realloc, and removing the ALLOCATED variable.
20439 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20441 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20442 But keep the doprint source code for now, as we might revamp it
20443 and use it again (Bug#8435).
20444 * lisp.h (doprnt): Remove.
20445 * Makefile.in (base_obj): Remove doprnt.o.
20446 * deps.mk (doprnt.o): Remove.
20448 error: Print 32- and 64-bit integers portably (Bug#8435).
20449 Without this change, on typical 64-bit hosts error ("...%d...", N)
20450 was used to print both 32- and 64-bit integers N, which relied on
20451 undefined behavior.
20452 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20453 * lisp.h (error, verror): Mark as printf-like functions.
20454 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20455 Report overflow in size calculations when allocating printf buffer.
20456 Do not truncate output string at its first null byte.
20457 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20458 Truncate the output at a character boundary, since vsnprintf does not
20460 * charset.c (check_iso_charset_parameter): Convert internal
20461 character to string before calling 'error', since %c now has the
20463 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20464 overflow when computing char to be passed to 'error'. Do not
20465 pass Lisp_Object to 'error'; pass the integer instead.
20466 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20467 formatted with plain %d.
20469 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20471 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20473 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20475 * xterm.c (x_catch_errors): Remove duplicate declaration.
20477 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20479 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20481 2011-04-10 Jim Meyering <meyering@redhat.com>
20483 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20484 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20485 return ssize_t not "int", and use size_t as the buffer length.
20486 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20487 * gnutls.h: Update declarations.
20488 * process.c (read_process_output): Use ssize_t, to match.
20489 (send_process): Likewise.
20491 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20493 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20495 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20497 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20498 Use unsigned char, to match FcChar8 type definition.
20500 * xterm.c (handle_one_xevent):
20501 * xmenu.c (create_and_show_popup_menu):
20502 * xselect.c (x_decline_selection_request)
20503 (x_reply_selection_request): Avoid type-punned deref of X events.
20505 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20507 Fix some uses of `int' instead of EMACS_INT.
20508 * search.c (string_match_1, fast_string_match)
20509 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20510 (scan_buffer, find_next_newline_no_quit)
20511 (find_before_next_newline, search_command, Freplace_match)
20512 (Fmatch_data): Make some `int' variables be EMACS_INT.
20514 * xdisp.c (display_count_lines): 3rd argument and return value now
20515 EMACS_INT. All callers changed.
20516 (pint2hrstr): Last argument is now EMACS_INT.
20518 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20519 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20520 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20521 (decode_coding_utf_16, decode_coding_emacs_mule)
20522 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20523 (decode_coding_ccl, decode_coding_charset)
20524 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20525 (decode_coding_iso_2022, decode_coding_emacs_mule)
20526 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20527 <char_offset, last_offset>: Declare EMACS_INT.
20528 (encode_coding_utf_8, encode_coding_utf_16)
20529 (encode_coding_emacs_mule, encode_invocation_designation)
20530 (encode_designation_at_bol, encode_coding_iso_2022)
20531 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20532 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20534 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20535 (encode_invocation_designation): Last argument P_NCHARS is now
20537 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20538 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20540 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20543 * ccl.c (Fccl_execute_on_string): Declare some variables
20546 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20548 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20550 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20552 * process.c (Fformat_network_address): Doc fix.
20554 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20556 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20558 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20560 * keyboard.c (read_char): Call Lisp function help-form-show,
20561 instead of using internal_with_output_to_temp_buffer.
20562 (Qhelp_form_show): New var.
20563 (syms_of_keyboard): Use DEFSYM macro.
20565 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20567 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20569 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20571 * process.c (Flist_processes): Remove to Lisp.
20572 (list_processes_1): Delete.
20574 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20576 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20578 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20580 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20582 Fix more problems found by GCC 4.6.0's static checks.
20584 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20586 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20588 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20590 * xdisp.c (vmessage): Mark as a printf-like function.
20592 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20594 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20596 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20597 printf-like functions.
20598 (tiff_load): Add casts to remove these marks before passing them
20599 to system-supplied API.
20601 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20603 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20604 This avoids several warnings with gcc -Wstrict-overflow.
20605 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20606 directly, rather than having caller test rule sign. This avoids
20607 some unnecessary tests.
20608 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20609 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20610 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20612 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20613 (xfont_open): Avoid unnecessary tests.
20615 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20617 * composite.h, composite.c (composition_gstring_put_cache):
20618 Use EMACS_INT, not int, for length.
20620 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20621 breaking out part of COMPOSITION_DECODE_RULE.
20622 (COMPOSITION_DECODE_RULE): Use it.
20623 * composite.c (get_composition_id): Remove unused local vars,
20624 by using the new macro.
20626 * textprop.c (set_text_properties_1): Change while to do-while,
20627 since the condition is always true at first.
20629 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20630 (interval_deletion_adjustment): Return unsigned value.
20633 * process.c (list_processes_1, create_pty, read_process_output):
20634 (exec_sentinel): Remove vars that were set but not used.
20635 (create_pty): Remove unnecessary "volatile"s.
20636 (Fnetwork_interface_info): Avoid possibility of int overflow.

20638 (read_process_output): Simplify nbytes computation if buffered.
20640 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
20642 * syntax.c (scan_words): Remove var that was set but not used.
20643 (update_syntax_table): Use unsigned instead of int.
20645 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20646 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20647 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20649 * print.c (print_error_message): Avoid int overflow.
20651 * font.c (font_list_entities): Redo for clarity,
20652 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20654 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20655 (font_score): Avoid potential overflow in diff calculation.
20657 * fns.c (substring_both): Remove var that is set but not used.
20658 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20660 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20662 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20663 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20664 can always succeed if overflow has undefined behavior.
20666 * search.c (boyer_moore, wordify): Remove vars set but not used.
20667 (wordify): Omit three unnecessary tests.
20669 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20670 All callers changed. This avoids the need for an unused var.
20672 * casefiddle.c (casify_region): Remove var that is set but not used.
20674 * dired.c (file_name_completion): Remove var that is set but not used.
20676 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20678 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20679 (Finsert_file_contents): Remove unnecessary code checking fd.
20681 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20682 Check for integer overflow on size calculations.
20684 * buffer.c (Fprevious_overlay_change): Remove var that is set
20687 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20688 Remove vars that are set but not used.
20689 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20690 (timer_check_2): Mark vars as initialized.
20692 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20694 * image.c (lookup_image): Remove var that is set but not used.
20695 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20697 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20698 that are set but not used.
20700 * xfns.c (make_invisible_cursor): Don't return garbage
20701 if XCreateBitmapFromData fails (Bug#8410).
20703 * xselect.c (x_get_local_selection, x_handle_property_notify):
20704 Remove vars that are set but not used.
20706 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20707 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20709 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20710 Remove var that is set but not used.
20711 (scroll_bar_windows_size): Now size_t, not int.
20712 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20713 Check for overflow.
20715 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20716 (map_tty_color) [!defined MSDOS]: Likewise.
20718 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20720 * coding.c: Remove vars that are set but not used.
20721 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20722 All callers changed.
20723 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20724 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20725 (decode_coding_charset): Remove vars that are set but not used.
20727 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20728 that is set but not used.
20730 * print.c (print_object): Remove var that is set but not used.
20732 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20733 The gnulib version avoids calling malloc in the usual case,
20734 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20735 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20736 * filelock.c (current_lock_owner): Likewise.
20737 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20738 * sysdep.c: Include allocator.h, careadlinkat.h.
20739 (emacs_no_realloc_allocator): New static constant.
20740 (emacs_readlink): New function.
20741 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20742 ../lib/careadlinkat.h.
20744 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20746 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20747 first non-nil return value).
20749 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20751 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20752 if not defined (Bug#8403).
20754 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20756 * xdisp.c (display_count_lines): Remove parameter `start',
20757 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20758 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20759 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20760 (fill_stretch_glyph_string): Remove parameters `row' and `area',
20761 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20762 and thereabouts. All callers changed.
20763 (get_per_char_metric): Remove parameter `f', unused since
20764 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20766 2011-04-02 Jim Meyering <meyering@redhat.com>
20768 do not dereference NULL upon failed strdup
20769 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20770 (ns_get_family): Likewise.
20772 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20774 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20776 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20778 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20781 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20783 Add lexical binding.
20785 * window.c (Ftemp_output_buffer_show): New fun.
20786 (Fsave_window_excursion):
20787 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20789 * lread.c (lisp_file_lexically_bound_p): New function.
20790 (Fload): Bind Qlexical_binding.
20791 (readevalloop): Remove `evalfun' arg.
20792 Bind Qinternal_interpreter_environment.
20793 (Feval_buffer): Bind Qlexical_binding.
20794 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20796 (syms_of_lread): Declare `lexical-binding'.
20798 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20800 * keyboard.c (eval_dyn): New fun.
20801 (menu_item_eval_property): Use it.
20803 * image.c (parse_image_spec): Use Ffunctionp.
20805 * fns.c (concat, mapcar1): Accept byte-code-functions.
20807 * eval.c (Fsetq): Handle lexical vars.
20808 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20809 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20810 (FletX, Flet): Obey lexical binding.
20811 (Fcommandp): Handle closures.
20812 (Feval): New `lexical' arg.
20813 (eval_sub): New function extracted from Feval. Use it almost
20814 everywhere where Feval was used. Look up vars in lexical env.
20816 (Ffunctionp): Move from subr.el.
20817 (Ffuncall): Handle closures.
20818 (apply_lambda): Remove `eval_flags'.
20819 (funcall_lambda): Handle closures and new byte-code-functions.
20820 (Fspecial_variable_p): New function.
20821 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20822 but without exporting it to Lisp.
20824 * doc.c (Fdocumentation, store_function_docstring):
20825 * data.c (Finteractive_form): Handle closures.
20827 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20830 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20832 (exec_byte_code): New function extracted from Fbyte_code to handle new
20833 calling convention for byte-code-functions. Add new byte-codes.
20835 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20837 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20839 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20841 * xdisp.c (redisplay_internal): Fix prototype.
20843 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20845 * xdisp.c (SCROLL_LIMIT): New macro.
20846 (try_scrolling): Use it when setting scroll_limit.
20847 Limit scrolling to 100 screen lines.
20848 (redisplay_window): Even when falling back on "recentering",
20849 position point in the window according to scroll-conservatively,
20850 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20852 (try_scrolling): When point is above the window, allow searching
20853 as far as scroll_max, or one screenful, to compute vertical
20854 distance from PT to the scroll margin position. This prevents
20855 try_scrolling from unnecessarily failing when
20856 scroll-conservatively is set to a value slightly larger than the
20857 window height. Clean up the case of PT below the margin at bottom
20858 of window: scroll_max can no longer be INT_MAX. When aggressive
20859 scrolling is in use, don't let point enter the opposite scroll
20860 margin as result of the scroll.
20861 (syms_of_xdisp) <scroll-conservatively>: Document the
20862 threshold of 100 lines for never-recentering scrolling.
20864 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20866 * dispextern.h (move_it_by_lines):
20867 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20868 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20869 (message_log_check_duplicate): Remove parameters `prev_bol' and
20870 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20871 (redisplay_internal): Remove parameter `preserve_echo_area',
20872 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20874 * indent.c (Fvertical_motion):
20875 * window.c (window_scroll_pixel_based, Frecenter):
20876 Don't pass `need_y_p' to `move_it_by_lines'.
20878 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20880 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20881 steal a few bits to be more compact.
20882 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20883 Remove unneeded casts.
20885 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20887 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20889 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20890 binding" message (bug#7967).
20892 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20894 Fix more problems found by GCC 4.6.0's static checks.
20896 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20897 Remove unused local var.
20899 * editfns.c (Fmessage_box): Remove unused local var.
20901 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20902 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20903 Omit unused local vars.
20904 * window.c (shrink_windows): Omit unused local var.
20905 * menu.c (digest_single_submenu): Omit unused local var.
20906 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20907 Omit unused local var.
20909 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20910 Don't assume string length fits in int.
20911 (keyremap_step, read_key_sequence): Use size_t for sizes.
20912 (read_key_sequence): Don't check last_real_key_start redundantly.
20914 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20915 instead of alloca (Bug#8344).
20917 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20918 (Fbacktrace_frame): Don't assume nframes fits in int.
20920 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20922 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20925 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20927 * cm.c (calccost): Turn while-do into do-while, for clarity.
20929 * keyboard.c (syms_of_keyboard): Use the same style as later
20930 in this function when indexing through an array. This also
20931 works around GCC bug 48267.
20933 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20935 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

20938 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20940 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20941 This avoids undefined behavior on integer overflow, and is a bit
20942 more convenient anyway since it is compared to a size_t variable.
20944 Variadic C functions now count arguments with size_t, not int.
20945 This avoids an unnecessary limitation on 64-bit machines, which
20946 caused (substring ...) to crash on large vectors (Bug#8344).
20947 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20948 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20949 All variadic functions and their callers changed accordingly.
20950 (struct gcpro.nvars): Now size_t, not int. All uses changed.

20954 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20955 (funcall_lambda, mark_backtrace): Likewise.
20956 * fns.c (concat): Likewise.
20957 * frame.c (x_set_frame_parameters): Likewise.
20958 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20959 0 if not found, not -1. All callers changed.
20961 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20962 (stack_copy_size): Now size_t, not int.
20963 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20967 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20968 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20969 All callers changed.
20971 * lisp.h (multibyte_char_to_unibyte):
20972 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20973 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20974 * character.h (CHAR_TO_BYTE8):
20975 * cmds.c (internal_self_insert):
20976 * editfns.c (general_insert_function):
20977 * keymap.c (push_key_description):
20978 * search.c (Freplace_match):
20979 * xdisp.c (message_dolog, set_message_1): All callers changed.
20981 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20983 * keyboard.c (safe_run_hook_funcall): New function.
20984 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20985 don't set the hook to nil, but remove the offending function instead.
20986 (Qcommand_hook_internal): Remove, unused.
20987 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20988 Vcommand_hook_internal.
20990 * eval.c (enum run_hooks_condition): Remove.
20991 (funcall_nil, funcall_not): New functions.
20992 (run_hook_with_args): Call each function through a `funcall' argument.
20993 Remove `cond' argument, now redundant.
20994 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20995 (Frun_hook_with_args_until_failure): Adjust accordingly.
20996 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
20998 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21000 * dispextern.h (string_buffer_position): Remove declaration.
21002 * print.c (strout): Remove parameter `multibyte', unused since
21003 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21005 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21006 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21007 All callers changed.
21009 * w32.c (_wsa_errlist): Use braces for struct initializers.
21011 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21012 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21013 All callers changed.
21014 (string_buffer_position): Likewise. Also, make static (it's never
21015 used outside xdisp.c).
21016 (cursor_row_p): Remove parameter `w', unused since
21017 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21019 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21020 All callers changed.
21022 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21024 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21035 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21037 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21050 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21052 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21053 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21055 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21057 * w32.c (read_unc_volume): Use parameter `henum', instead of
21058 global variable `wget_enum_handle'.
21060 * keymap.c (describe_vector): Remove parameters `indices' and
21061 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21072 * w32menu.c (w32_menu_display_help):
21073 * xmenu.c (show_help_event, menu_help_callback):
21074 Adjust calls to `show_help_echo'.
21076 * gtkutil.c (xg_maybe_add_timer):
21077 * keyboard.c (readable_events):
21078 * process.c (wait_reading_process_output):
21079 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21081 * insdel.c (adjust_markers_gap_motion):
21082 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21156 2011-03-23 Julien Danjou <julien@danjou.info>
21158 * term.c (Fsuspend_tty, Fresume_tty):
21159 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21160 * window.c (temp_output_buffer_show):

21165 * editfns.c (save_excursion_restore):
21166 * cmds.c (internal_self_insert):
21167 * callint.c (Fcall_interactively):
21168 * buffer.c (Fkill_all_local_variables):
21169 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21171 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21172 unconditionally since it does the check itself.
21174 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21176 Fix more problems found by GCC 4.5.2's static checks.
21178 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21179 the first time through the loop, since we know p0 < p1 then.
21180 This also avoids a gcc -Wstrict-overflow warning.
21182 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21183 leading to a memory leak, possible in functions like
21184 load_charset_map_from_file that can allocate an unbounded number
21185 of objects (Bug#8318).
21187 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21188 that could (at least in theory) be that large.
21190 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21191 This is less likely to overflow, and avoids undefined behavior if
21192 overflow does occur. All callers changed. Use strtoul to scan
21193 for the unsigned long integer.
21194 (pint2hrstr): Simplify and tune code slightly.
21195 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21203 This also avoids a warning with gcc -Wstrict-overflow.
21205 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21208 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21210 * process.c (Fmake_network_process): Use socklen_t, not int,
21211 where POSIX says socklen_t is required in portable programs.
21212 This fixes a porting bug on hosts like 64-bit HP-UX, where
21213 socklen_t is wider than int (Bug#8277).
21214 (Fmake_network_process, server_accept_connection):
21215 (wait_reading_process_output, read_process_output):
21218 * process.c: Rename or move locals to avoid shadowing.
21219 (list_processes_1, Fmake_network_process):
21220 (read_process_output_error_handler, exec_sentinel_error_handler):
21221 Rename or move locals.
21222 (Fmake_network_process): Define label "retry_connect" only if needed.
21223 (Fnetwork_interface_info): Fix pointer signedness.
21224 (process_send_signal): Add cast to avoid pointer signedness problem.
21225 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21226 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21228 Make tparam.h and terminfo.c consistent.
21229 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21230 Include tparam.h instead, since it declares them.
21231 * cm.h (PC): Remove extern decl; tparam.h now does this.
21232 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21233 * terminfo.c: Include tparam.h, to check interfaces.
21234 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21235 (tparam): Adjust signature to match interface in tparam.h;
21236 this removes some undefined behavior. Check that outstring and len
21237 are zero, which they always are with Emacs.
21238 * tparam.h (PC, BC, UP): New extern decls.
21240 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21241 (xftfont_open): Rename locals to avoid shadowing.
21243 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21244 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21245 (OTF_TAG_SYM): Omit macro if not needed.
21246 (ftfont_list): Remove unused local.
21247 (get_adstyle_property, ftfont_pattern_entity):
21248 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21249 Rename locals to avoid shadowing.
21251 * xfont.c (xfont_list_family): Mark var as initialized.
21253 * xml.c (make_dom): Now static.
21255 * composite.c (composition_compute_stop_pos): Rename local to
21257 (composition_reseat_it): Remove unused locals.
21258 (find_automatic_composition, composition_adjust_point): Likewise.
21259 (composition_update_it): Mark var as initialized.
21260 (find_automatic_composition): Mark vars as initialized,
21261 with a FIXME (Bug#8290).
21263 character.h: Rename locals to avoid shadowing.
21264 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21265 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21266 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21267 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21268 to avoid shadowing.
21270 * textprop.c (property_change_between_p): Remove; unused.
21272 * intervals.c (interval_start_pos): Now static.
21274 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21276 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21277 Rename locals to avoid shadowing.
21279 * sound.c (wav_play, au_play, Fplay_sound_internal):
21280 Fix pointer signedness.
21281 (alsa_choose_format): Remove unused local var.
21282 (wav_play): Initialize a variable to 0, to prevent undefined
21283 behavior (Bug#8278).
21285 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21287 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21289 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21290 clobbering (Bug#8298).
21291 * sysdep.c (sys_subshell): Likewise.
21292 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21294 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21295 This should get cleaned up, so that child_setup has the
21296 same signature on all platforms.
21298 * callproc.c (call_process_cleanup): Now static.
21299 (relocate_fd): Rename locals to avoid shadowing.
21301 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

21468 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21469 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21470 to use the following functions instead of these macros.
21471 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21472 EMACS_INT, since callers assume the returned value fits in int.
21473 (upcase1): Likewise, for UPCASE_TABLE.
21474 (uppercasep, lowercasep, upcase): New static inline functions.
21475 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21485 (regex_compile, re_match_2_internal): Mark locals as initialized.
21486 (RETALLOC_IF): Define only if needed.
21487 (WORDCHAR_P): Likewise. This one is never needed, but is used
21488 only in a comment talking about a compiler bug, so put inside
21489 the #if 0 of that comment.
21490 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21491 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21517 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21518 New macros, so that the caller can use some names other than
21519 gcpro1, gcpro2, etc.
21520 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21522 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21523 argument, for consistency with GCPRO2_VAR, etc: it is now the
21524 prefix of the variable, not the variable itself. All uses
21526 * dired.c (directory_files_internal, file_name_completion):
21527 Rename locals to avoid shadowing.
21529 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21530 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21531 dired.c's scmp function, had undefined behavior.
21532 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21533 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21534 * buffer.h: ... to here, because these macros use current_buffer,
21535 and the new implementation with inline functions needs to have
21536 current_buffer in scope now, rather than later when the macros
21538 (downcase, upcase1): New static inline functions.
21539 (DOWNCASE, UPCASE1): Reimplement using these functions.
21540 This avoids undefined behavior in expressions like
21541 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21542 from race conditions in accessing the global variables
21543 case_temp1 and case_temp2.
21544 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21545 * lisp.h (case_temp1, case_temp2): Remove their decls.
21546 * character.h (ASCII_CHAR_P): Move from here ...
21547 * lisp.h: ... to here, so that the inline functions mentioned
21548 above can use them.
21550 * dired.c (directory_files_internal_unwind): Now static.
21552 * fileio.c (file_name_as_directory, directory_file_name):

21555 (file_name_as_directory): Use const pointers when appropriate.
21556 (Fexpand_file_name): Likewise. In particular, newdir might
21557 point at constant storage, so make it a const pointer.
21558 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21559 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21561 (Fset_file_times, Finsert_file_contents, auto_save_error):

21566 to avoid shadowing.
21568 * marker.c (bytepos_to_charpos): Remove; unused.
21570 * lisp.h (verify_bytepos, count_markers): New decls,
21571 so that gcc does not warn that these functions aren't declared.
21573 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21574 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21575 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21576 (copy_text): Remove unused local var.
21578 * filelock.c (within_one_second): Now static.
21579 (lock_file_1): Rename local to avoid shadowing.
21581 * buffer.c (fix_overlays_before): Mark locals as initialized.
21582 (fix_start_end_in_overlays): Likewise. This function should be
21583 simplified by using pointers-to-pointers, but that's a different
21585 (switch_to_buffer_1): Now static.
21586 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21587 (report_overlay_modification): Rename locals to avoid shadowing.
21589 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21590 Fix pointer signedness issue.
21591 (sys_subshell): Mark local as volatile if checking for lint,
21592 to suppress a gcc -Wclobbered warning that does not seem to be right.
21593 (MAXPATHLEN): Define only if needed.
21595 * process.c (serial_open, serial_configure): Move decls from here ...
21596 * systty.h: ... to here, so that they can be checked.
21598 * fns.c (get_random, seed_random): Move extern decls from here ...
21599 * lisp.h: ... to here, so that they can be checked.
21601 * sysdep.c (reset_io): Now static.
21602 (wait_for_termination_signal): Remove; unused.
21604 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21607 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21608 (DENSE_TABLE_SIZE): Remove; unused.
21609 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21610 (describe_map_tree):
21611 Rename locals to avoid shadowing.
21613 * keyboard.c: Declare functions static if they are not used elsewhere.
