3 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
6 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
7 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
8 updateCollectionBehaviour.
10 * nsterm.m (NEW_STYLE_FS): Remove.
11 (ns_last_use_native_fullscreen): New variable.
12 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
13 (x_set_window_size): Do not take title bar and tool bar into account
14 if isFullscreen returns YES.
15 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
16 (check_native_fs): New function.
17 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
18 (ns_term_init): Remove NEW_STYLE_FS.
19 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
20 and tool bar if isFullscreen returns NO.
21 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
22 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
24 (window:willUseFullScreenPresentationOptions:): New method.
25 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
26 Hide toolbar if not enabled (Bug#13444).
27 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
28 Restore tool bar if enabled, hide it otherwise (Bug#13444).
29 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
30 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
31 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
32 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
33 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
34 (syms_of_nsterm): Add ns-use-native-fullscreen.
36 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
38 * fileio.c (Qchoose_write_coding_system): Now static.
40 2013-02-04 Eli Zaretskii <eliz@gnu.org>
42 * xdisp.c (window_buffer_changed): region_showing can be negative,
43 which still means region is being displayed.
44 (redisplay_internal): Resurrect code that forced redisplay of the
45 whole window when showing region and the mark has changed. Record
46 the new mark position to allow redisplay optimizations.
47 (display_line): If it->region_beg_charpos is non-zero, set the
48 window's region_showing member to -1. (Bug#13623) (Bug#13626)
50 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
51 not bitfield of 1 bit.
53 2013-02-03 Daniel Colascione <dancol@dancol.org>
55 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
56 daemon mode works on cygw32 when Emacs is installed and not just
59 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
61 Avoid file time stamp bug on MS-Windows (Bug#13149).
62 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
63 as FAT32 doesn't update time stamps when truncating them.
64 Also, check that a file time stamp is not a multiple of 100 ns;
65 this should catch all instances of the problem on MS-Windows,
66 as its native file system resolution is 100 ns or worse, and
67 checking for a non-multiple of 100 ns should impose only a small
68 overhead on systems with ns resolution.
70 2013-02-02 Eli Zaretskii <eliz@gnu.org>
72 Avoid encoding file names on MS-Windows when they need to be run
73 through dostounix_filename.
74 * w32.c (normalize_filename): Accept an additional argument
75 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
76 downcase it even if w32-downcase-file-names is non-nil.
77 (dostounix_filename): Accept an additional argument MULTIBYTE and
78 pass it to normalize_filename.
79 (emacs_root_dir): Adjust.
81 * msdos.h (dostounix_filename): Adjust prototype.
83 * w32.h (dostounix_filename): Adjust prototype.
85 * msdos.c (dostounix_filename): Accept an additional argument and
87 (init_environment): Adjust callers of dostounix_filename.
89 * fileio.c (Ffile_name_directory, file_name_as_directory)
90 (directory_file_name, Fexpand_file_name)
91 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
93 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
95 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
96 variables, as egetenv is case-insensitive for DOS_NT.
98 * dired.c (file_name_completion): Don't call Fdirectory_file_name
99 with an encoded file name.
101 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust
102 calls to dostounix_filename.
104 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
106 * unexw32.c (unexec): Adjust call to dostounix_filename.
108 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
110 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
113 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
116 * callproc.c (Fcall_process): Make sure program name in PATH and
117 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
118 is passed to exec/spawnve, which fails unless the file-name
121 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
122 even if w32-quote-process-args is nil.
124 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
126 Fix timestamp bug when write-region appends nothing (Bug#13149).
127 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
128 the file's time stamp doesn't change if Emacs happens to write nothing
129 to the file, and on a buggy file system this could cause Emacs to
130 incorrectly infer that the file system doesn't have the bug.
131 Avoid this problem by inhibiting the inference in this case.
133 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
135 * window.h (struct window): Convert base_line_number, base_line_pos
136 and column_number_displayed members from Lisp_Object to ptrdiff_t.
137 Convert region_showing member from Lisp_Object to bitfield.
138 Remove sequence_number member. Adjust comments.
139 * window.c (sequence_number): Remove.
140 (make_window): Initialize column_number_displayed.
141 * print.c (print_object): Follow the printed representation of
142 frames and print window pointer to distinguish between windows.
143 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
144 * xdisp.c (wset_base_line_number, wset_base_line_pos)
145 (wset_column_number_displayed, wset_region_showing): Remove.
146 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
147 (try_scrolling, try_cursor_movement, redisplay_window)
148 (try_window_reusing_current_matrix, try_window_id, display_line)
149 (display_mode_lines, decode_mode_spec): Adjust users.
150 * .gdbinit (pwinx): Do not print sequence_number.
152 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
154 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
155 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
156 * dired.c: Include <fcntl.h>.
157 (open_directory): New function, which uses open and fdopendir
158 rather than opendir. DOS_NT platforms still use opendir, though.
159 (directory_files_internal, file_name_completion): Use it.
160 (file_attributes): New function, with most of the old Ffile_attributes.
161 (directory_files_internal, Ffile_attributes): Use it.
162 (file_attributes, file_name_completion_stat): First arg is now fd,
163 not dir name. All uses changed. Use fstatat rather than lstat +
165 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
166 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
167 (emacs_readlinkat): New function, with much of the old
168 Ffile_symlink_p, but with an fd argument for speed.
169 It uses readlinkat rather than careadlinkatcwd, so that it
170 need not assume the working directory.
171 (Ffile_symlink_p): Use it.
172 * filelock.c (current_lock_owner): Use emacs_readlinkat
173 rather than emacs_readlink.
174 * lisp.h (emacs_readlinkat): New decl.
175 (READLINK_BUFSIZE, emacs_readlink): Remove.
176 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
177 (emacs_norealloc_allocator, emacs_readlink): Remove.
178 This stuff is moved to fileio.c.
179 * w32.c (fstatat, readlinkat): New functions.
180 (careadlinkat): Don't check that fd == AT_FDCWD.
181 (careadlinkatcwd): Remove; no longer needed.
183 2013-01-31 Glenn Morris <rgm@gnu.org>
185 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
186 (Fwrite_region): Update for new choose_write_coding_system args.
187 Move the last piece of choose_write_coding_system here. (Bug#13522)
188 (syms_of_fileio): Add choose-write-coding-system.
190 2013-01-30 Eli Zaretskii <eliz@gnu.org>
192 * w32.c (sys_open): Zero out the flags for the new file descriptor.
193 (sys_close): Zero out the flags for the file descriptor before
194 closing it. (Bug#13546)
196 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
197 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
198 CharNextExA and CharPrevExA to iterate over file names encoded in
201 * w32.c (w32_get_long_filename, init_environment, readlink):
202 Support file names encoded in DBCS codepages.
203 (readlink): Use the current file-name-coding-system, not the ANSI
204 codepage, to decode and handle targets of symlinks.
206 2013-01-28 Eli Zaretskii <eliz@gnu.org>
208 * w32.c (opendir): Now accepts a 'const char *'.
210 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
212 Remove obsolete redisplay code. See the discussion at
213 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
214 * dispnew.c (preemption_period, preemption_next_check): Remove.
215 (Vredisplay_preemption_period): Likewise.
216 (update_frame, update_single_window, update_window, update_frame_1):
217 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
218 used, following the 2012-06-22 change.
220 2013-01-25 Eli Zaretskii <eliz@gnu.org>
222 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
224 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
226 * font.c (num_fonts): Remove the leftover from old
227 debugging code. Adjust comment style here and there.
228 * insdel.c (insert_1): Remove.
229 * lisp.h (insert_1): Remove prototype.
230 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
232 2013-01-25 Eli Zaretskii <eliz@gnu.org>
234 * w32.c (max_filename_mbslen): New function.
235 (normalize_filename, readdir): Use it to detect locales where ANSI
236 encoding of file names uses a double-byte character set (DBCS).
237 If a DBCS encoding is used, advance by characters using
238 CharNextExA, instead of incrementing a 'char *' pointer. Use
239 _mbslwr instead of _strlwr. (Bug#13515)
241 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
242 request of memory reservation to 1.7GB. (Bug#13065)
244 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
246 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
247 at check_extra_latin label. (Bug#13505)
249 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
251 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
252 Avoid redundant calls to strlen.
254 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
256 Drop async_visible and async_iconified fields of struct frame.
257 This is possible because async input is gone; for details, see
258 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
259 * frame.h (struct frame): Remove async_visible and async_iconified
260 members, convert garbaged to unsigned bitfield. Adjust comments.
261 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
262 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
263 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
264 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
265 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
267 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
268 properly. Likewise for obscured.
270 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
273 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
275 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
277 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
278 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
280 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
282 * xdisp.c (message2, message2_nolog): Remove functions.
283 (message3, message3_nolog): Extract nbytes and multibyteness directly
284 from the string. Change all callers.
285 (message3_nolog): Don't set message_enable_multibyte since set_message
286 will reset it anyway.
287 (message1, message1_nolog): Use message3.
288 (vmessage): Use a stack allocated buffer rather than f->message_buf.
289 (with_echo_area_buffer): Remove last two arguments. Update all callers.
290 (set_message): Drop all but the second arg, which has to be a string.
291 (set_message_1): Simplify now that we know that a1 is NULL and the
292 second arg is a string.
293 * frame.h (struct frame): Remove `message_buf' field.
294 Use glyphs_initialized_p instead.
295 (FRAME_MESSAGE_BUF): Remove macro.
296 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
297 * lisp.h (message2, message2_nolog): Remove declarations.
298 (message3, message3_nolog): Update declarations.
299 * keyboard.c (read_char_minibuf_menu_text)
300 (read_char_minibuf_menu_width): Remove vars.
301 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
302 to correctly handle multibyte strings.
303 * frame.c (delete_frame): Don't free message_buf any more.
304 * editfns.c (message_text, message_length): Remove vars.
305 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
306 * fileio.c (auto_save_error): Use message3 instead of message2.
307 * dispnew.c (adjust_frame_message_buffer): Remove function.
309 2013-01-23 Eli Zaretskii <eliz@gnu.org>
311 * w32term.c (w32fullscreen_hook): Account correctly for the screen
312 real estate used for the tool bar and the menu bar.
314 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
316 * insdel.c (prepare_to_modify_buffer): Force redisplay if
317 hidden buffer is prepared to modification (Bug#13164).
319 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
321 * window.h (struct window): Change window_end_valid member from
322 Lisp_Object to a bitfield. Adjust comments.
323 (wset_window_end_valid): Remove.
324 * window.c (adjust_window_count): Clear window_end_valid.
325 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
326 (Fwindow_line_height, set_window_buffer, Frecenter)
327 (Fsplit_window_internal, Fdelete_other_windows_internal)
328 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
329 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
330 * xdisp.c (check_window_end, reconsider_clip_changes)
331 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
332 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
333 (find_first_unchanged_at_end_row, try_window_id): Likewise.
335 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
337 * xdisp.c (mark_window_display_accurate): Simplify the loop
338 assuming that the only one of vchild, hchild or buffer window
339 slots is non-nil. Call mark_window_display_accurate_1 for
340 the leaf windows only.
341 (mark_window_display_accurate_1): Always assume leaf window.
344 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
346 * emacs.c (Qkill_emacs_hook): Now static.
348 * fileio.c (Finsert_file_contents): Simplify.
349 Remove unnecessary assignments and tests.
351 2013-01-21 Eli Zaretskii <eliz@gnu.org>
353 * w32.c (acl_set_file): Don't test for errors unless
354 set_file_security returns FALSE. Avoids spurious errors when
357 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
359 * fileio.c (Finsert_file_contents): Revert code introduced at
360 2013-01-18 in favor of the simpler and generally better fix.
361 Save stack space by removing 'buffer' and reusing 'read_buf'
364 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
366 * lisp.h (eabs): Define unconditionally (Bug#13419).
367 The old "#if !defined (eabs)" was an unnecessary revenant of back
368 when this macro was called "abs". Document 'eabs' better.
370 2013-01-19 Glenn Morris <rgm@gnu.org>
372 * fns.c (Frandom): Doc fix.
374 2013-01-19 Eli Zaretskii <eliz@gnu.org>
376 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
377 segfault when there are lots of overlays.
379 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
380 when there are lots of overlays. See
381 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
382 for the details and a way to reproduce.
384 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
386 * fileio.c: Use O_APPEND to append.
387 This corresponds better to the natural interpretation of "append",
388 and avoids the need to open the output file twice, or to invoke
389 lseek when APPEND is neither nil nor a number.
390 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
391 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
392 file possibly twice, and lseeking to its end; this avoids the
393 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
394 at the same time: the combination is never needed and apparently
395 it doesn't work with DOS_NT.
397 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
398 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
400 Allow floating-point file offsets.
401 Problem reported by Vitalie Spinu in
402 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
403 * fileio.c (emacs_lseek): Remove.
404 (file_offset): New function.
405 (Finsert_file_contents, Fwrite_region): Use it.
407 2013-01-19 Chong Yidong <cyd@gnu.org>
409 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
410 aborting on Fsignal (Bug#13289).
412 2013-01-19 Eli Zaretskii <eliz@gnu.org>
414 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
415 set_file_security as failure due to insufficient privileges.
416 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
417 (fstat): Return owner and group like 'stat' and 'lstat' do.
419 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
421 Work around bug in CIFS and vboxsf file systems (Bug#13149).
422 The bug was observed on Ubuntu operating inside a virtual machine,
423 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
424 The workaround introduces a race condition on non-buggy hosts,
425 but it's an unlikely race and anyway there's a nearly identical
426 nearby race that can't be fixed.
427 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
429 (Fwrite_region): Test for file system time stamp bug.
430 (init_fileio): New function.
431 * lisp.h (init_fileio): Declare it.
432 * emacs.c (main): Call it.
434 * fileio.c (Finsert_file_contents): Simplify new diagnostic
435 and make it more consistent with other stat-failure diagnostics.
437 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
439 Fix crash when inserting data from non-regular files. See
440 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
441 for the error description produced by valgrind.
442 * fileio.c (read_non_regular): Rename to read_contents.
443 Free Lisp_Save_Value object used to pass parameters.
444 (read_non_regular_quit): Rename to read_contents_quit.
445 (Finsert_file_contents): Redesign internal file reading loop to adjust
446 gap and end positions after each read and so help make_gap to work
447 properly. Do not signal an I/O error too early and so do not leave
448 not yet decoded characters in a buffer, which was the reason of
449 redisplay crash. Use list2 to build return value. Adjust comments.
451 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
453 Close a race when statting and reading files (Bug#13149).
454 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
455 This avoids a race if the file is renamed between stat and open.
456 This race is not the problem originally noted in Bug#13149;
457 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
459 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
461 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
462 objects, related functions and macros.
463 (make_save_value): Adjust prototype.
464 (make_save_pointer): New prototype.
465 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
466 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
467 * alloc.c (format_save_value): Rename to make_save_value.
468 (make_save_pointer): New function.
469 (record_xmalloc): Use make_save_pointer.
470 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
471 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:

556 * editfns.c (save_excursion_save): Pack everything within
557 Lisp_Save_Value and so avoid xmalloc.
558 (save_excursion_restore): Adjust to match new layout. Use free_misc
559 because we do not allocate extra memory any more. Add eassert.

643 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
645 * term.c (init_tty): Use them instead of rolling our own code.
646 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
647 switches from 'signal' to 'pthread_sigmask', which is safer in
648 multithreaded applications.
649 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
650 which has already arranged for that.
651 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

673 Use Qstringp for default-directory, buffer-file-name,
674 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
675 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
677 * data.c (store_symval_forwarding): Adjust to call the predicate.
679 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

720 trailing dash is properly added.
722 2013-01-05 Eli Zaretskii <eliz@gnu.org>
724 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
725 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
726 digits for buffer positions, before misalignment starts.
727 Display "0" for integer "object" field.
728 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
729 Display the newline glyph more unambiguously.
731 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
733 * nsterm.m (ns_draw_underwave):
734 * w32term.c (w32_draw_underwave):
735 * xterm.c (x_draw_underwave): Make underwave look more triangular
736 and also degrade gracefully for small fonts. (Bug#13000)
738 * nsterm.m (ns_draw_text_decoration):
739 * w32term.c (x_draw_glyph_string):
740 * xterm.c (x_draw_glyph_string): Don't use previous underline

765 2012-12-31 Eli Zaretskii <eliz@gnu.org>
767 * w32.c (unsetenv): Set up the string passed to _putenv
769 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
770 for the bug this caused.
772 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
774 * coding.c (Qmac): Now static.
776 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
778 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
779 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

781 toolbar_is_packed to true.
782 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
783 (update_frame_tool_bar): Check toolbar_is_packed for packing.
784 Show all on TOOLBAR_TOP_WIDGET.
785 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
786 by TOOLBAR_TOP_WIDGET.
787 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
788 Check toolbar_is_packed.
789 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
790 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
791 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
793 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
794 (xg_update_menubar): Update title only if
795 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
796 (xg_update_submenu): Skip tearoff only if
797 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
798 (xg_initialize): Initialize xg_detached_menus only if
799 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
801 * xterm.h (struct x_output): Surround handlebox_widget with
802 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

805 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
807 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
808 (LIBS_GNUSTEP): Define.
809 (LIBES): Add $(LIBS_GNUSTEP).
810 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
812 2012-12-30 Eli Zaretskii <eliz@gnu.org>
814 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
815 continuation glyph on a TTY with an indication of an empty line.
818 2012-12-29 Eli Zaretskii <eliz@gnu.org>
820 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
821 file's SELinux context or ACLs successfully set, nil otherwise.
823 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
825 * w32proc.c (reader_thread): Avoid passing NULL handles to
826 SetEvent and WaitForSingleObject.
828 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
830 Port EXTERNALLY_VISIBLE to Clang 3.2.
831 * conf_post.h (__has_attribute): New macro.
832 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
834 2012-12-27 Glenn Morris <rgm@gnu.org>
836 * cygw32.c (Fcygwin_convert_file_name_to_windows)

841 * fileio.c (file_name_as_directory, directory_file_name):
842 Accept an additional argument MULTIBYTE to indicate whether the input C
843 came from a multibyte or a unibyte Lisp string; all callers
844 adjusted. Don't assume the input string is always multibyte.
846 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
847 don't ENCODE_FILE them, and return a unibyte string if the input
849 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
850 don't assume the input strings will always be multibyte. If the
851 input strings are multibyte, decode strings obtained from C
854 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
856 * lisp.h (toplevel): Add two notices to the comment about
857 defining a new Lisp data type.
858 * print.c (print_object): If Lisp_Save_Value object's pointer
859 is the address of a memory area containing Lisp_Objects, try
861 * alloc.c (valid_lisp_object_p): Adjust comment.
863 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
865 * keyboard.c (record_asynch_buffer_change): Initialize an event
866 only if it's really needed.
867 * frame.h (enum output_method): Remove output_mac member since
868 it's a leftover from the deleted code.
869 * frame.c (Fframep): Adjust user here ...
870 * terminal.c (Fterminal_live_p): ... and here.
871 * coding.c (Qmac): Now here because it's only used to denote
872 end-of-line encoding type.
873 (syms_of_coding): DEFSYM it.
874 * frame.h (Qmac): Remove duplicated declaration.
876 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
878 * window.c (select_window_1): Now static, since it's used only here.
880 2012-12-25 Eli Zaretskii <eliz@gnu.org>
882 * window.c (window_body_cols): Subtract display margins from the
883 window body width on TTYs as well. See
884 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
885 for the original report.
887 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
889 * xdisp.c (redisplay_window): Remove inner local variable
890 because the outer shadowed one has the same meaning.
891 * xterm.h (struct x_output): Remove toolbar_detached member since it's
893 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
894 (xg_create_tool_bar): Adjust users.
896 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
898 * buffer.h (BUF_COMPACT): New macro to follow the common style.
899 * buffer.c (Fget_buffer_create): Use it to set compact field of
900 struct buffer_text to avoid accessing an uninitialized value
901 when compact_buffer is called for the first time.
902 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
903 (Fset_buffer_modified_p): Use buffer_window_count to check
904 whether the buffer is displayed in some window.
905 * xdisp.c (message_dolog): Likewise.
907 2012-12-23 Eli Zaretskii <eliz@gnu.org>
909 * w32.c (acl_set_file): If setting the file security descriptor
910 fails, and the new DACL is identical to the existing one, silently
911 return success. This fixes problems for users backing up their
912 own files without having the necessary privileges for setting
913 security descriptors.
915 * w32proc.c (reader_thread): Do not index fd_info[] with negative
917 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
918 after WaitForSingleObject returns normally. This expedites reader
919 thread shutdown when delete_child triggers it.
920 (reap_subprocess): More accurate commentary for why we call
921 delete_child only when cp->fd is negative.
923 * w32.c (sys_close): Do not call delete_child on a subprocess
924 whose handle is not yet closed. Instead, set its file descriptor
925 to a negative value, so that reap_subprocess will call
926 delete_child on that subprocess when its SIGCHLD arrives.
927 This avoids closing handles used for communications between sys_select
928 and reader_thread, which doesn't give sys_select a chance to
929 notice that the process exited and invoke the SIGCHLD handler for
932 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
934 * nsfns.m (Fns_do_applescript): Run event loop until script has
935 been executed (Bug#12969).
936 (ns_run_ascript): Chech as_script for nil, set to nil after
939 2012-12-22 Martin Rudalics <rudalics@gmx.at>
941 * window.c (Fselect_window): Reword doc-string (Bug#13248).
943 2012-12-22 Eli Zaretskii <eliz@gnu.org>
945 * w32term.c (w32fullscreen_hook): New function.
946 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
948 2012-12-21 Eli Zaretskii <eliz@gnu.org>
950 * fileio.c (Finsert_file_contents): Doc fix.
952 * w32proc.c (new_child, delete_child, find_child_pid): For a
953 subprocess, consider its slot being in use as long as its process
954 handle (procinfo.hProcess) is not NULL. This avoids reusing the
955 slot when a new process is started immediately after killing
956 another one, without waiting enough time for the first process to
957 be reaped and resources allocated for it be orderly freed.

976 2012-12-21 Chong Yidong <cyd@gnu.org>
978 * editfns.c (Finsert_char): Since read-char-by-name now signals an

1022 * w32.c (acl_get_file, acl_set_file): Run the file name through

1069 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1070 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1071 for some of that bug's symptoms can now cause Emacs to abort.
1072 Remove the workaround.
1073 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1074 The bug that caused SIGCHLD to get lost has been fixed, and the

1119 * callproc.c (Fcall_process): Don't overwrite infile with result
1121 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1122 asynchronous subprocess, record the name of the input file name,
1124 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1125 delete the file, record it as pending deletion when the subprocess
1128 2012-12-14 Eli Zaretskii <eliz@gnu.org>

1148 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1150 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1151 try to get accurate owner and group information from NT file
1152 security APIs. This is to make most callers of 'stat' and
1153 'lstat', which don't need that information, much faster.
1155 * dired.c (Ffile_attributes) [WINDOWSNT]:
1156 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1157 owner and group information from 'lstat'.
1159 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1161 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1162 as that confuses set-auto-coding, so insist on the head-read

1187 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1188 files, fixing a regression from 24.2.
1189 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1191 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1193 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1194 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1195 Remove unnecessary S_ISLNK test, as (contra the comments) this
1196 function can't copy symlinks. Improve quality of error message
1197 when attempting to copy files that are neither regular files nor

1216 * inotify.c (inotify_callback): Generate an Emacs event for every
1217 incoming inotify event.
1219 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1221 * xdisp.c (handle_face_prop): Fix logic of computing
1222 it->start_of_box_run_p.

1224 iterator's end_of_box_run_p flag before prepending the space glyph.
1225 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1226 iterator's start_of_box_run_p flag before prepending the stretch.

1228 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1229 left_box_line_p and right_box_line_p flags of the glyph for R2L
1230 glyph rows. (Bug#13011)

1442 (Fset_time_zone_rule): Do not save TZ and environ;
1443 no longer needed here.
1444 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1445 Move to inside set_time_zone_rule; they don't need file scope any more.
1446 (set_time_zone_rule): Maintain the TZ=value string separately.
1447 (syms_of_editfns): Don't initialize initial_tz;
1448 init_editfns now does it.
1449 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1450 * lisp.h (xputenv): New decl.
1452 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1454 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1456 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1458 * w32.c (unsetenv, sys_putenv): New functions.
1460 2012-12-08 Chong Yidong <cyd@gnu.org>
1462 * editfns.c (Finsert_char): Make the error message more
1463 informative (Bug#12992).
1465 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1467 Simplify get_lim_data.
1468 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1469 Remove USG and vlimit methods; no longer used these days.
1470 Add #error catchall just in case.
1472 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1473 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1474 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1475 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1476 (deleted_pid_list, Fdelete_process, create_process)
1477 (record_child_status_change, handle_child_signal, deliver_child_signal)
1478 (init_process_emacs, syms_of_process):
1479 Assume SIGCHLD is defined.
1480 (parse_signal): Remove. All uses removed.
1481 (abbr_to_signal): New static function.
1482 (Fsignal_process): Use it to convert signal names to ints.
1483 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1484 kill (getpgrp (), ...).
1485 (emacs_sigaction_init): Assume SIGCHLD is defined.
1486 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1487 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1488 * syssignal.h (EMACS_KILLPG): Remove.
1489 All uses replaced by 'kill' with a negative pid.
1490 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1491 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1493 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1495 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1496 This will cause a production Emacs to dump core instead of
1499 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1501 * frame.c (make_frame): Do not set window's buffer to t.
1502 * window.c (Fsplit_window_internal): Likewise. Previously it was
1503 used to indicate that the window is being set up. Now we use
1504 set_window_buffer for all new windows, so the condition in ...
1505 (Fset_window_buffer): ... is always true and can be removed.
1507 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1509 Convenient macro to check whether the buffer is hidden.
1510 * buffer.h (BUFFER_HIDDEN_P): New macro.
1511 * frame.c (make_frame): Use it. Adjust comment.
1512 * buffer.c (candidate_buffer): New function.
1513 (Fother_buffer, other_buffer_safely): Use it.
1515 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1517 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1518 if the child process is still running. Instead, exit the wait
1519 loop and return zero. (Bug#13086)
1521 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1523 * frame.h (x_char_width, x_char_height): Remove prototypes.
1524 * w32term.h (x_char_width, x_char_height): Likewise.
1525 * xfns.c (x_char_width, x_char_height): Remove.
1526 * w32fns.c (x_char_width, x_char_height): Likewise.
1527 * nsfns.c (x_char_width, x_char_height): Likewise.
1528 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for

1534 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1536 Fix a recently-introduced delete-process race condition.
1537 * callproc.c, process.h (record_kill_process):
1538 New function, containing part of the old call_process_kill.
1539 (call_process_kill): Use it.
1540 This does not change call_process_kill's behavior.
1541 * process.c (Fdelete_process): Use record_kill_process to fix a
1542 race condition that could cause Emacs to lose track of a child.
1544 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1546 Avoid code duplication between prev_frame and next_frame.
1547 * frame.c (candidate_frame): New function. Add comment.
1548 (prev_frame, next_frame): Use it. Adjust comment.
1550 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1552 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1553 fails, signal an error instead of continuing with an empty
1555 Encode expanded temp file pattern before passing it to mkstemp or
1558 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1559 Encode the file name before passing it to dostounix_filename, in
1560 case it will downcase it (under w32-downcase-file-names).
1563 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1565 Minor call-process cleanups.
1566 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1567 at the same time as other platforms, to simplify analysis.
1568 No need for fd0_volatile since we have synch_process_fd.
1569 Avoid needless emacs_close; arg is always negative.
1571 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1573 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1576 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1578 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1579 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1580 and mouse_face_hidden members to a bitfields.
1581 * frame.h (struct frame): Remove set-but-not-used space_width member.
1582 (FRAME_SPACE_WIDTH): Remove.
1583 * nsterm.m, w32term.c, xterm.c: Adjust users.
1584 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1585 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1586 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1587 members to a bitfields.
1589 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1591 Don't let call-process be a zombie factory (Bug#12980).
1592 Fixing this bug required some cleanup of the signal-handling code.
1593 As a side effect, this change also fixes a longstanding rare race
1594 condition whereby Emacs could mistakenly kill unrelated processes,
1595 and it fixes a bug where a second C-g does not kill a recalcitrant
1596 synchronous process in GNU/Linux and similar platforms.
1597 The patch should also fix the last vestiges of Bug#9488,
1598 a bug which has mostly been fixed on the trunk by other changes.
1599 * callproc.c, process.h (synch_process_alive, synch_process_death)
1600 (synch_process_termsig, sync_process_retcode):
1601 Remove. All uses removed, to simplify analysis and so that
1602 less consing is done inside critical sections.
1603 * callproc.c (call_process_exited): Remove. All uses replaced
1604 with !synch_process_pid.
1605 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1606 These take the role of what used to be in unwind-protect arg.
1608 (block_child_signal, unblock_child_signal):
1609 New functions, to avoid races that could kill innocent-victim processes.
1610 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1611 (call_process_kill): Record killed processes as deleted, so that
1612 zombies do not clutter up the system. Do this inside a critical
1613 section, to avoid a race that would allow the clutter.
1614 (call_process_cleanup): Fix code so that the second C-g works again
1615 on common platforms such as GNU/Linux.
1616 (Fcall_process): Create the child process in a critical section,
1617 to fix a race condition. If creating an asynchronous process,
1618 record it as deleted so that zombies do not clutter up the system.
1619 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1620 light of these changes. Omit unnecessary call to emacs_close
1621 before failure, as the unwind-protect code does that.
1622 * callproc.c (call_process_cleanup):
1623 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1624 * process.c (record_deleted_pid): New function, containing
1625 code refactored out of Fdelete_process.
1626 (Fdelete_process): Use it.
1627 (process_status_retrieved): Remove. All callers changed to use
1628 child_status_change.
1629 (record_child_status_change): Remove, folding its contents into ...
1630 (handle_child_signal): ... this signal handler. Now, this
1631 function is purely a handler for SIGCHLD, and is not called after
1632 a synchronous waitpid returns; the synchronous code is moved to
1633 wait_for_termination. There is no need to worry about reaping
1634 more than one child now.
1635 * sysdep.c (get_child_status, child_status_changed): New functions.
1636 (wait_for_termination): Now takes int * status and bool
1637 interruptible arguments, too. Do not record child status change;
1638 that's now the caller's responsibility. All callers changed.
1639 Reimplement in terms of get_child_status.
1640 (wait_for_termination_1, interruptible_wait_for_termination):
1641 Remove. All callers changed to use wait_for_termination.
1642 * syswait.h: Include <stdbool.h>, for bool.
1643 (record_child_status_change, interruptible_wait_for_termination):
1645 (record_deleted_pid, child_status_changed): New decls.
1646 (wait_for_termination): Adjust to API changes noted above.
1648 * bytecode.c, lisp.h (Qbytecode): Remove.
1649 No longer needed after 2012-11-20 interactive-p changes.
1651 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1653 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1654 the scroll margin, move point outside the margin. (Bug#13055)
1656 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1658 * gtkutil.c (my_log_handler): New function.
1659 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1661 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1663 * lisp.h (modify_region): Rename to...
1664 (modify_region_1): ...new prototype.
1665 * textprop.c (modify_region): Now static. Adjust users.
1666 * insdel.c (modify_region): Rename to...
1667 (modify_region_1): ...new function to work with current buffer.
1668 Adjust comment and users. Use true and false for booleans.
1670 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1672 * alloc.c (free_save_value): New function.
1673 (safe_alloca_unwind): Use it.
1674 * lisp.h (free_save_value): New prototype.
1675 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1677 (save_excursion_restore): Adjust to match saved data structure.
1678 Use free_save_value to offload some work from GC. Drop obsolete
1681 2012-12-03 Chong Yidong <cyd@gnu.org>
1683 * fileio.c (Vauto_save_list_file_name): Doc fix.
1685 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1687 * w32fns.c: Remove prototype of atof.
1688 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1690 (file_dialog_callback): Make it UINT_PTR.
1692 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1695 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1696 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1699 2012-12-03 Glenn Morris <rgm@gnu.org>
1701 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1703 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1705 Fix xpalloc confusion after memory is exhausted.
1706 * alloc.c (xpalloc): Comment fix.
1707 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1708 and signals an error, do not clear charset_table_size, as
1709 charset_table is still valid.
1710 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1712 Use execve to avoid need to munge environ (Bug#13054).
1713 * callproc.c (Fcall_process):
1714 * process.c (create_process):
1715 Don't save and restore environ; no longer needed.
1716 * callproc.c (child_setup):
1717 Use execve, not execvp, to preserve environ.
1719 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1721 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1723 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1725 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1726 display for sliced images (Bug#10500).
1728 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1730 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1732 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1733 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1735 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1737 * xdisp.c (window_outdated): Remove eassert since it hits
1738 some suspicious corner cases (see Bug#13007 and Bug#13012).
1739 (mode_line_update_needed): New function.
1740 (redisplay_internal, redisplay_window): Use it.
1741 (ensure_selected_frame): New function.
1742 (redisplay_internal, unwind_redisplay): Use it.
1743 (redisplay_internal): Move comment about buffer_shared...
1744 (buffer_shared_and_changed): ...near to its real use.
1746 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1748 * callproc.c (Fcall_process): Don't misreport vfork failure.
1750 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1752 * callproc.c (Fcall_process): Fix vfork portability problems.
1753 Do not assume that fd[0], count, filefd, and save_environ survive
1754 vfork. Fix bug whereby wrong errno value could be reported for
1755 pipe failure. Some minor cleanups, too, as follows. Move buf and
1756 bufsize to the context where they're needed. Change new_argv to
1757 be of type char **, as this is more convenient and avoids casts.
1758 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1759 Now local constants, not macros.
1761 2012-11-18 Kenichi Handa <handa@gnu.org>
1763 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1764 for the variable "f".
1766 2012-11-13 Kenichi Handa <handa@gnu.org>
1768 * font.c (font_unparse_xlfd): Exclude special characters from the
1769 generating XLFD name.
1771 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1773 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1784 * lread.c (readbyte_from_file): Assume EINTR is defined.
1785 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1786 Assume EIO and EAGAIN are defined.
1787 * unexcoff.c (write_segment): Assume EFAULT is defined.
1789 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1791 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1794 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1795 highlighting on the frame was cleared. Prevents assertion
1796 violations when repeatedly clicking on the "Top" link of the
1797 "bread-crumbs" in Info buffers.
1799 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

1806 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1807 were always defined.
1809 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1811 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1812 between bpos_covered and bpos_max. This fixes cursor display when
1813 several display strings follow each other.
1815 * .gdbinit (pgx): If the glyph's object is a string, display the
1816 pointer to string data, rather than the value of the string object
1817 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1819 * indent.c (Fvertical_motion): If the starting position is covered
1820 by a display string, return to one position before that, to avoid
1821 overshooting it inside move_it_to. (Bug#12930)
1823 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1825 * frame.h (struct frame): Remove display_preempted member

1830 (set_frame_menubar): Adjust user.
1831 * w32term.h (struct x_output): Drop outdated #if 0 code.
1832 (struct w32_output): Use bitfields for explicit_parent,
1833 asked_for_visible and menubar_active members.
1834 Drop unused pending_menu_activation member.
1835 * xterm.h (struct x_output): Drop outdated #if 0 code.
1836 Use bitfields for explicit_parent, asked_for_visible,
1837 has_been_visible and net_wm_state_hidden_seen members.

1841 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1842 of a literal "/". (Bug#12955)
1843 (gl-stamp): Invoke fc.exe directly, not through cmd.
1845 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

1848 * dired.c: Assume HAVE_DIRENT_H.
1849 (NAMLEN): Remove, replacing with ...
1850 (dirent_namelen): New function. All uses changed. Use the GNU macro
1851 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1852 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1853 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1854 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1856 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1857 * ndir.h: Rename to ../nt/inc/dirent.h.
1858 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1859 Do not include <dirent.h>; no longer needed.
1860 * w32.c: Include <dirent.h> rather than "ndir.h".
1862 2012-11-23 Chong Yidong <cyd@gnu.org>
1864 * xftfont.c (xftfont_open): Remove duplicate assignment.
1866 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1868 * alloc.c (Fgarbage_collect): Unblock input after clearing
1869 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1870 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1871 * msdos.c (IT_frame_up_to_date): Use it here...
1872 * w32term.c (w32_frame_up_to_date): ...here...
1873 * xterm.c (XTframe_up_to_date): ...and here...
1874 * nsterm.m (ns_frame_up_to_date): ...but not here.
1875 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1877 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1878 Do not check whether GC is in progress.
1880 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1882 * xdisp.c (window_buffer_changed): New function.
1883 (update_menu_bar, update_tool_bar): Use it to
1884 simplify large 'if' statements.
1885 (redisplay_internal): Generalize commonly used
1886 'tail' and 'frame' local variables.
1888 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1890 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1891 with Windows system header.
1893 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1895 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1896 * alloc.c: Assume unistd.h exists.
1897 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1898 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1899 (getwd) [USG]: Remove; no longer needed.
1900 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1901 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1902 * w32.h (getcwd): Remove decl.
1904 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1906 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1907 Make it set selected_window as well.
1908 (update_tool_bar): Use it.
1910 2012-11-21 Ken Brown <kbrown@cornell.edu>
1912 * emacs.c (main): Set the G_SLICE environment variable for all
1913 Cygwin builds, not just GTK builds. See
1914 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1916 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1918 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1919 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1920 Define for the MSVC compiler.
1922 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1924 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1925 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1926 dostounix_filename. Prevents crashes down the road, because
1927 dostounix_filename assumes it gets a unibyte string.
1928 Reported by Michel de Ruiter <michel@sentient.nl>, see
1929 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1931 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1935 * lread.c (init_obarray): Set `function' fields to Qnil.
1936 * eval.c (Fcommandp): Ignore Qunbound.
1937 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1938 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1939 Test NILP rather than Qunbound.
1940 (Ffmakunbound): Set to Qnil.
1941 (Fsymbol_function): Never signal an error.
1942 (Finteractive_form): Ignore Qunbound.
1944 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1946 * eval.c (interactive_p): Remove no-longer-used decl.
1948 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1950 * xdisp.c (buffer_shared): Adjust comment.
1951 (buffer_shared_and_changed): New function.
1952 (prepare_menu_bars, redisplay_internal): Use it to
1953 decide whether all windows or frames should be updated.
1954 (window_outdated): New function.
1955 (text_outside_line_unchanged_p, redisplay_window): Use it.
1956 (redisplay_internal): Likewise. Fix indentation.
1958 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1960 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1961 (syms_of_eval): Remove corresponding defsubr.
1962 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1964 2012-11-19 Daniel Colascione <dancol@dancol.org>
1966 * w32fns.c (Fx_file_dialog):
1967 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1968 cygwin_convert_file_name*.
1970 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1971 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1973 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1975 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1977 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1979 * w32select.c: Include w32common.h before w32term.h, so that
1980 windows.h gets included before w32term.h uses some of its
1981 features, see below.
1983 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1985 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1987 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1989 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1991 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1992 (ns_select): Return at once if events are held (Bug#12834).
1994 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1996 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1997 Needed following 2012-10-20 change. (Bug#12902)
1999 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2001 * w32proc.c (waitpid): Remove unused label get_result.
2003 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2005 * makefile.w32-in (SYSWAIT_H): New macro.
2006 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2007 ($(BLD)/sysdep.$(O)): Update dependencies.
2009 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2011 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2012 * callproc.c (relocate_fd): Assume F_DUPFD.
2013 * emacs.c, term.c (O_RDWR): Remove.
2014 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2015 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2016 * nsterm.m: Assume <fcntl.h> exists.
2017 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2018 (create_pty, Fmake_network_process, server_accept_connection)
2019 (wait_reading_process_output, init_process_emacs):
2021 (wait_reading_process_output): Put in a special case for WINDOWSNT
2022 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2023 It's not clear this is needed, but it's a more-conservative change.
2024 (create_process): Assume FD_CLOEXEC.
2025 (create_process, create_pty): Assume O_NOCTTY.
2026 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2027 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2028 Omit if not DOS_NT, since F_GETFL is not defined there.
2029 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2030 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2032 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2033 lack it, since gnulib guarantees this.
2034 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2036 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2038 * w32.c (faccessat): Pretend that directories have the execute bit
2039 set. Emacs expects that, e.g., in files.el:cd-absolute.
2041 * w32proc.c (create_child): Don't clip the PID of the child
2042 process to fit into an Emacs integer, as this is no longer a
2044 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2045 reaping only the process specified by PID argument, if that is
2046 positive. Use PID instead of dead_child to know which process to
2047 reap. Wait for the child to die only if WNOHANG is not in
2049 (sys_select): Don't set dead_child.
2051 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2052 as it is no longer needed.
2054 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2056 (record_child_status_change): Remove the setting of
2057 record_at_most_one_child for the !WNOHANG case.
2059 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2061 Fix problems in ns port found by static checking.
2062 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2063 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2064 not to process group.
2065 (ns_select): Use emacs_write, not write, as that's more robust
2066 in the presence of signals.
2067 (fd_handler:): Check for read errors.
2069 2012-11-16 Glenn Morris <rgm@gnu.org>
2071 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2073 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2075 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2077 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2079 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2080 use the same value of thread handle.
2081 (start_timer_thread): If the timer thread exited (due to error),
2082 clean up by closing the two handles it used. Duplicate the caller
2083 thread's handle here, so it gets duplicated only once, when
2084 launching the timer thread. Set priority of the timer thread, not
2086 (getitimer): Don't duplicate the caller thread's handle here.
2089 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2091 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2094 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2096 Remove no-longer-used pty_max_bytes variable.
2097 * process.c (pty_max_bytes): Remove; unused.
2098 (send_process): Do not set it.
2100 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2102 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2103 Update dependencies.
2105 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2107 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2108 This follows up on the 2012-09-29 patch that removed indirection
2109 for the 'function' field. Reported by Sergey Vinokurov in
2110 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2112 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2114 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2115 different name, as the MS runtime does not have such a function,
2116 and probably never will.) All callers changed. Ignore DIRFD
2117 value if PATH is an absolute file name, to match Posix spec
2118 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2121 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2123 * xdisp.c (echo_area_display, redisplay_internal):
2124 Omit redundant check whether frame_garbaged is set.
2126 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2128 Use faccessat, not access, when checking file permissions (Bug#12632).
2129 This fixes a bug that has been present in Emacs since its creation.
2130 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2131 which must set some sort of record. (Torek's bug report was against
2132 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2133 same common flaw.) See Torek's Usenet posting
2134 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2135 Posted: Fri Apr 8 14:18:56 1983.
2136 * Makefile.in (LIB_EACCESS): New macro.
2138 * callproc.c (init_callproc):
2139 * charset.c (init_charset):
2140 * fileio.c (check_existing, check_executable, check_writable)
2142 * lread.c (openp, load_path_check):
2143 * process.c (allocate_pty):
2145 Use effective UID when checking permissions, not real UID.
2146 * callproc.c (init_callproc):
2147 * charset.c (init_charset):
2148 * lread.c (load_path_check, init_lread):
2149 Test whether directories are accessible, not merely whether they exist.
2150 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2151 * fileio.c (check_existing, check_executable, check_writable)
2153 Use symbolic names instead of integers for the flags, as they're
2155 (check_writable): New arg AMODE. All uses changed.
2156 Set errno on failure.
2157 (Ffile_readable_p): Use faccessat, not stat + open + close.
2158 (Ffile_writable_p): No need to call check_existing + check_writable.
2159 Just call check_writable and then look at errno. This saves a syscall.
2160 dir should never be nil; replace an unnecessary runtime check
2161 with an eassert. When checking the parent directory of a nonexistent
2162 file, check that the directory is searchable as well as writable, as
2163 we can't create files in unsearchable directories.
2164 (file_directory_p): New function, which uses 'stat' on most platforms
2165 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2166 (Ffile_directory_p, Fset_file_times): Use it.
2167 (file_accessible_directory_p): New function, which uses a single
2168 syscall for efficiency.
2169 (Ffile_accessible_directory_p): Use it.
2170 * xrdb.c (file_p): Use file_directory_p.
2171 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2172 * lread.c (openp): When opening a file, use fstat rather than
2173 stat, as that avoids a permissions race. When not opening a file,
2174 use file_directory_p rather than stat.
2175 (dir_warning): First arg is now a usage string, not a format.
2176 Use errno. All uses changed.
2177 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2178 that merely introduced a race.
2179 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2180 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2181 and similarly for the other O_* flags.
2182 * w32.c (sys_faccessat): Rename from sys_access and switch to
2183 faccessat's API. All uses changed.
2184 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2185 (magic_db): Rename from magic_file_p.
2186 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2187 char *, so that we don't have to test for file existence
2188 separately from opening the file for reading. This removes a race
2189 fixes a permission-checking problem, and simplifies the code.
2191 (file_p): Remove; no longer needed.
2193 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2195 Omit glyphs initialization at startup.
2196 * dispnew.c (glyphs_initialized_initially_p): Remove.
2197 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2198 (Fredraw_frame): Move actual code from here...
2199 (redraw_frame): ...to here. Add eassert. Adjust comment.
2200 (Fredraw_display): Use redraw_frame.
2201 * xdisp.c (clear_garbaged_frames): Likewise.
2203 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2205 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2206 passed to pint2str and pint2hrstr to be at most the size of the
2207 frame's decode_mode_spec_buffer. This avoids crashes with very
2208 large values of FIELD_WIDTH argument to decode_mode_spec.
2211 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2213 Fix a race with verify-visited-file-modtime (Bug#12863).
2214 Since at least 1991 Emacs has ignored an mtime difference of no
2215 more than one second, but my guess is that this was to work around
2216 file system bugs that were fixed long ago. Since the race is
2217 causing problems now, let's remove that code.
2218 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2219 whose time stamp is off by no more than a second. Insist that the
2220 file time stamps match exactly.
2222 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2224 * frame.h (struct frame): Convert external_tool_bar member to
2225 1-bit unsigned bitfield.
2226 * termhooks.h (struct terminal): Remove mouse_moved member since
2227 all users are long dead. Adjust comment on mouse_position_hook.
2229 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2231 Simplify by using FOR_EACH_FRAME here and there.
2232 * frame.c (next_frame, prev_frame, other_visible_frames)
2233 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2234 * w32term.c (x_window_to_scroll_bar): Likewise.
2235 * window.c (window_list): Likewise.
2236 * xdisp.c (x_consider_frame_title): Likewise.
2237 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2238 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2239 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2240 * xmenu.c (menubar_id_to_frame): Likewise.
2241 * xselect.c (frame_for_x_selection): Likewise.
2242 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2243 (x_window_to_menu_bar): Likewise.
2244 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2246 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2248 * data.c (Qdefalias_fset_function): Now static.
2250 Another tweak to vectorlike_header change.
2251 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2252 Remove, and replace all uses with ...
2253 (next_in_free_list, set_next_in_free_list):
2254 New functions, which respect C's aliasing rules better.
2256 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2258 * window.c (list4i): Rename from 'quad'. All uses changed.
2259 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2261 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2263 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2264 warning about mixing declarations and code in ISO C90.
2266 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2268 * window.c (Fsplit_window_internal): Set combination limit of
2269 new parent window to t iff Vwindow_combination_limit is t;
2270 fixing a regression introduced with the change from 2012-09-22.
2271 (Fset_window_combination_limit): Fix doc-string.
2273 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2275 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2276 amount when the scroll margins are too large. When scrolling
2277 backwards in the buffer, give up if cannot reach point or the
2278 scroll margin within a reasonable number of screen lines.
2279 Fixes point position in window under scroll-up/down-aggressively when
2280 point is positioned many lines beyond the window top/bottom.
2283 * ralloc.c (relinquish): If real_morecore fails to return memory
2284 to the system, don't crash; instead, leave the last heap
2285 unchanged and return. (Bug#12774)
2287 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2289 * lisp.h (AUTOLOADP): New macro.
2290 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2291 * data.c (Ffset): Remove special ad-advice-info handling.
2292 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2294 (Finteractive_form): Simplify.
2295 (Fquo): Don't insist on having at least 2 arguments.
2296 (Qdefalias_fset_function): New var.
2298 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2300 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2302 * nsfont.m (Qcondensed, Qexpanded): New variables.
2303 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2304 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2306 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2308 Fix recently introduced crash on MS-Windows (Bug#12839).
2309 * w32term.h (struct scroll_bar): Use convenient header.
2310 (SCROLL_BAR_VEC_SIZE): Remove.
2311 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2313 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2315 Tweak last vectorlike_header change.
2316 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2317 vectorlike object on the free list. This is introduced to avoid
2318 some (but not all) pointer casting and aliasing problems, see
2319 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2320 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2322 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2324 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2326 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2327 been removed, so remove them here also.
2329 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2331 * doc.c (Fdocumentation): Handle new property
2332 dynamic-docstring-function to replace the old ad-advice-info.
2334 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2336 * fns.c (Qeql, hashtest_eq): Now static.
2338 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2340 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2341 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2342 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2343 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2345 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2347 Use same hash function for hashfn_profiler as for hash_string etc.
2348 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2349 * lisp.h (sxhash_combine): New inline function, with the contents
2350 of the old SXHASH_COMBINE.

2352 special hash function containing a comparison that always yields 1.
2354 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2356 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2357 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2358 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2361 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2363 * image.c (xpm_make_color_table_h): Fix compiler error because
2364 make_hash_table changed.
2366 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2368 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2370 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2372 Use ad-hoc comparison function for the profiler's hash-tables.
2373 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2374 (make_log): Use them.

2385 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2386 (hash_lookup, hash_remove_from_table): Move assertion checking of
2387 hashfn result here. Check hash-equality before calling cmpfn.

2397 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2399 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2400 value of w32-scroll-lock-modifier is neither nil nor one of the
2401 known key modifiers. (Bug#12806)
2403 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2405 Shrink struct vectorlike_header to the only size field.
2406 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2408 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

2410 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2411 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2412 information from the vector header. Adjust comment.

2427 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2428 (large_vectors): Change type to struct large_vector.
2429 (allocate_vector_from_block): Simplify.
2430 (PSEUDOVECTOR_NBYTES): Replace with...

2433 (allocate_vectorlike): Likewise.
2434 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2435 Add easserts. Adjust XSETPVECTYPESIZE usage.
2436 (allocate_buffer): Use BUFFER_PVEC_INIT.
2437 (live_vector_p): Adjust to match large vector.
2438 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2439 * buffer.h (struct buffer): Add next member.

2450 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2452 * keyboard.c (event_to_kboard): Do not dereference
2453 frame_or_window field of SELECTION_REQUEST_EVENT
2454 and SELECTION_CLEAR_EVENT events (Bug#12814).
2455 * xterm.h (struct selection_input_event): Adjust comment.
2457 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2459 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2460 such as Scroll Lock, if the respective keys are treated as
2461 function keys, not as modifiers. This avoids destroying non-ASCII
2462 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2464 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2466 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2468 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2470 Restore some duplicate definitions (Bug#12814).
2471 This undoes part of the 2012-11-03 changes. Some people build
2472 with plain -g rather than with -g3, and they need the duplicate
2473 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2474 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2475 Define as macros, as well as as enums or as constants.
2477 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2479 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2480 to keypad keys (Bug#12816).
2482 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2484 Minor adjustments of recently-changed frame functions.
2485 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2486 known to be a frame (we're in the FRAMEP branch).
2487 * lisp.h (Qframep): Remove decl. frame.h declares this.
2488 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2489 since they're meant for Lisp fixnum values.
2491 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2493 * window.c (Fwindow_combination_limit): Revert to the only
2494 required argument and adjust docstring as suggested in
2495 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2496 by Martin Rudalics <rudalics@gmx.at>.
2498 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2500 Widely used frame validity and checking functions.
2501 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2502 * frame.c (decode_live_frame, decode_any_frame): New functions.
2503 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2504 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2505 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2513 * lisp.h (frame_buffer_predicate): Remove prototype.
2514 * buffer.c (Fother_buffer): Use decode_any_frame.
2515 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2516 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2517 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2518 (Fclose_font, Ffont_info): Use decode_live_frame.
2519 * fontset.c (check_fontset_name): Likewise.
2520 * terminal.c (Fframe_terminal): Likewise.
2521 * w32fns.c (check_x_frame): Likewise.
2522 * window.c (Fminibuffer_window, Fwindow_at)
2523 (Fcurrent_window_configuration): Likewise.
2524 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2525 Likewise. Allow zero number of arguments. Adjust docstring.

2527 * xfaces.c (frame_or_selected_frame): Remove.
2528 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2529 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2530 (Fframe_face_alist): Use decode_live_frame.
2531 * xfns.c (check_x_frame): Likewise.
2533 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2535 * window.c (quad): New function.
2536 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2537 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2538 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2539 (Fwindow_line_height): Use it.
2540 (Fwindow_fringes): Use list3.
2541 (Fwindow_scroll_bars): Use list4.
2542 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2543 (Fwindow_combination_limit): Allow zero number of arguments.
2545 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2547 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2549 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2550 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2551 file descriptor 2 for standard error. (Bug#12805)
2553 2012-11-05 Chong Yidong <cyd@gnu.org>
2555 * process.c (wait_reading_process_output): Revert previous change.
2557 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2559 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2560 This removes code that has been obsolete since around 1990.
2561 * callproc.c (Fcall_process):
2563 * process.c (create_process):
2564 * term.c (dissociate_if_controlling_tty):
2565 Assume setsid exists.
2566 * callproc.c (child_setup): Assume setpgid exists and behaves as
2567 per POSIX.1-1988 or later.
2568 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2569 * emacs.c (shut_down_emacs):
2570 * sysdep.c (sys_suspend, init_foreground_group):
2571 Assume getpgrp behaves as per POSIX.1-1998 or later.
2572 * msdos.c (setpgrp): Remove.
2573 (tcgetpgrp, setpgid, setsid): New functions.
2574 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2575 * term.c (no_controlling_tty): Remove; unused.
2576 * w32proc.c (setpgrp): Remove.
2577 (setsid, tcgetpgrp): New functions.
2579 Simplify by assuming __fpending.
2580 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2581 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2582 Do not assume that __fpending's result fits in int.
2584 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2586 Remove EMACS_OUTQSIZE+sleep hack.
2587 * dispnew.c (update_frame_1): Remove hack for terminals slower
2588 than 2400 bps, which throttled Emacs by having it sleep.
2589 This code hasn't worked since at least 2007, when the multi-tty stuff
2590 was added, and anyway those old terminals are long dead.
2591 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2592 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2594 Fix data-loss with --version (Bug#9574).
2595 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2596 as we can't assume that emacs_strerror is initialized, and strerror
2597 is good enough here.
2598 (main): Invoke atexit earlier, to catch earlier instances of
2599 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2601 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2603 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2604 (keyDown): Remap keypad keys to X11 virtual key codes.
2606 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2608 Fix data-loss with --batch (Bug#9574).
2609 * emacs.c: Include <close-stream.h>.
2610 (close_output_streams): New function.
2611 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2612 and handles errors appropriately.
2613 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2616 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2617 The symptom is a diagnostic "GLib-WARNING **: In call to
2618 g_spawn_sync(), exit status of a child process was requested but
2619 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2620 waitpid(), so exit status can't be returned." The diagnostic
2621 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2622 The real bug is a race condition between Emacs and glib: Emacs
2623 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2624 so that glib can't find it. Work around the bug by invoking
2625 waitpid only on subprocesses that Emacs itself creates.
2626 * process.c (create_process, record_child_status_change):
2627 Don't use special value -1 in pid field, as the caller now must
2628 know the pid rather than having the callee infer it.
2629 The inference was sometimes incorrect anyway, due to another race.
2630 (create_process): Set new 'alive' member if child is created.
2631 (process_status_retrieved): New function.
2632 (record_child_status_change): Use it.
2633 Accept negative 1st argument, which means to wait for the
2634 processes that Emacs already knows about. Move special-case code
2635 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2636 processes that have already been waited for, by testing and
2637 clearing new 'alive' member.
2638 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2639 now does this internally.
2640 (handle_child_signal): Let record_child_status_change do all
2641 the work, since we do not want to reap all exited child processes,
2642 only the child processes that Emacs itself created.
2643 * process.h (Lisp_Process): New boolean member 'alive'.
2645 Omit duplicate definitions no longer needed with gcc -g3.
2646 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2647 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2648 Define only as macros. There's no longer any need to also define
2649 these symbols as enums or as constants, since we now assume
2650 gcc -g3 when debugging.
2652 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2654 * lisp.mk: Adjust comments to the fact that term/internal is now
2655 loaded from loadup.el.
2657 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2658 (msdos_fatal_signal): New function.
2659 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2662 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2663 for GCC versions before 4.
2664 (emacs_raise): Define to call msdos_fatal_signal.
2666 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2667 iterator when starting in the middle of a display or overlay
2670 2012-11-03 Chong Yidong <cyd@gnu.org>
2672 * process.c (wait_reading_process_output): Clean up the last
2675 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2677 * process.c (wait_reading_process_output): Avoid a race condition

2684 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2686 * frame.h (struct frame): Drop can_have_scroll_bars member
2687 which is meaningless for a long time. Adjust comments.
2688 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2689 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2691 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2693 * window.c (decode_next_window_args): Update window arg after
2694 calling decode_live_window and so fix crash reported at
2695 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2696 by Juanma Barranquero <lekktu@gmail.com>.
2697 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2698 * font.c (Ffont_at): Likewise.
2700 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2702 * widget.c (resize_cb): New function.
2703 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2704 (EmacsFrameResize): Check if all is up to date before changing frame
2707 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2709 Implement backtrace output for fatal errors on MS-Windows.
2710 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2711 (BACKTRACE_LIMIT_MAX): New macro.
2712 (w32_backtrace): New function.
2713 (emacs_abort): Use w32_backtrace when the user chooses not to
2714 attach a debugger. Update the text of the abort dialog.
2716 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2718 Window-related stuff cleanup here and there.
2719 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2720 Use decode_any_window.
2721 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2722 * xdisp.c (Fformat_mode_line): Likewise.
2723 * font.c (Ffont_at): Use decode_live_window.

2728 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2729 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2732 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2734 Remove pad from struct input_event.
2735 * termhooks.h (struct input_event): Remove padding field.
2737 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2738 member is never cons for a long time. Adjust comment.
2739 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2740 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2741 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2742 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2744 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2746 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2748 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2750 Fix crash when using Emacs as commit editor for git (Bug#12697).
2751 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2752 and it is configured in conf_post.h.
2753 (Fcall_process): Don't invoke both setsid and setpgid; the former
2754 is enough, if it exists.
2755 * callproc.c (Fcall_process, child_setup):
2756 * process.c (create_process): Use setpgid.
2757 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2759 * dispnew.c (init_display): Initialize the foreground group
2760 if we are running a tty display.
2761 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2762 * lisp.h (init_foreground_group): New decl.
2763 * sysdep.c (inherited_pgroup): New static var.
2764 (init_foreground_group, tcsetpgrp_without_stopping)
2765 (narrow_foreground_group, widen_foreground_group): New functions.
2766 (init_sys_modes): Narrow foreground group.

2773 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2775 * minibuf.c (read_minibuf): Restore current buffer since
2776 choose_minibuf_frame calling Fset_frame_selected_window may
2777 change it (Bug#12766).
2779 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2781 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2783 2012-10-30 Kenichi Handa <handa@gnu.org>
2785 * font.c (Ffont_at): If WINDOW is specified and it is not
2786 displaying the current buffer, signal an error.
2788 2012-10-29 Daniel Colascione <dancol@dancol.org>
2790 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2791 In preparation for fixing bug#12739, move these functions from
2794 * coding.h, coding.c: ... to here, and compile them only when
2795 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2796 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2798 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2800 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2801 (timer_loop, getitimer, setitimer): Use it instead of
2802 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2804 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2807 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2809 * nsterm.m (NO_APPDEFINED_DATA): New define.
2810 (last_appdefined_event_data): New variable
2811 (last_appdefined_event): Remove.
2812 (ns_select): Initialize t from last_appdefined_event_data instead
2813 of [last_appdefined_event data1].
2814 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2815 remove last_appdefined_event (Bug#12698).
2817 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2819 * frame.c (x_set_font): Catch internal error.
2821 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2823 Avoid overflow in w32 implementation of interval timers.
2824 When possible, for ITIMER_PROF count only times the main thread
2826 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2827 'volatile ULONGLONG' types. All the other data which was
2828 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2829 (GetThreadTimes_Proc): New typedef.
2830 (w32_get_timer_time): New function, returns a suitable time value
2832 (timer_loop): Enter critical section when accessing ULONGLONG
2833 values of the itimer_data struct, as these accesses are no longer
2834 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2835 Remove unused variable.
2836 (init_timers): Initialize s_pfn_Get_Thread_Times.
2837 (start_timer_thread): Don't assign itimer->caller_thread here.
2838 (getitimer): Assign itimer->caller_thread here.
2839 (setitimer): Always call getitimer to get the value of ticks_now.

2844 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2845 mouse movement events if the menu bar is active. This avoids
2846 producing a busy "hour-glass" cursor by Windows if the mouse
2847 pointer is positioned over a tooltip shown for some menu item.
2849 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2851 Don't assume process IDs fit in int.
2852 * emacs.c (shut_down_emacs) [!DOS_NT]:
2853 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2854 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2855 Use pid_t, not int, to store process IDs, as 'int'
2856 is not wide enough on a few platforms (e.g., AIX and IRIX).
2858 2012-10-23 Kenichi Handa <handa@gnu.org>
2860 The following change is to make face-font-rescale-alist work
2861 correctly for non-ASCII fonts.
2863 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2864 (font_open_for_lface): Handle Vface_font_rescale_alist.
2866 2012-10-23 Chong Yidong <cyd@gnu.org>
2868 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2870 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2879 2012-10-21 Glenn Morris <rgm@gnu.org>
2881 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2883 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2885 Port to OpenBSD 5.1.
2886 * frame.c (Fmouse_position, Fmouse_pixel_position):
2887 * xdisp.c (produce_stretch_glyph):
2888 Declare local vars only when they're needed.
2889 This is clearer and avoids a warning on OpenBSD about unused vars.

2891 This is safer, and avoids OpenBSD warnings about unused vars.
2892 * keyboard.c (record_menu_key): Remove unnecessary decl.
2893 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2894 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2895 as our definition clashes with OpenBSD's.
2896 * xfaces.c (load_face_colors, check_lface_attrs)
2897 (get_lface_attributes_no_remap, get_lface_attributes)
2898 (lface_fully_specified_p, x_supports_face_attributes_p)
2899 (tty_supports_face_attributes_p, face_fontset, realize_face)
2900 (realize_x_face, realize_tty_face):
2901 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2902 merely Lisp_Object *. This is more informative and avoids
2903 a warning on OpenBSD about accessing beyond an object's size.
2905 2012-10-20 Chong Yidong <cyd@gnu.org>
2907 * lread.c (Fload): Doc fix (Bug#12592).

2911 * font.c (Ffont_at): Fix previous change.
2913 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2915 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2916 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

2933 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2934 (staticpro): If we run out of staticpro slots, die with an
2935 informative error instead of just calling emacs_abort.
2937 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2939 Fix two flaws reported by Dmitry Antipov.

3194 since unsigned is guaranteed to have that behavior and signed is not.
3195 (read_char): Use ptrdiff_t for string length.
3196 (get_input_pending): Remove first argument, since it was always
3197 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3198 and behave as if it had that value. Return new value of
3199 input_pending. All callers changed.
3200 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3201 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3244 match what GetLastError returns. Explain why the function is
3247 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3248 'is_tooltip_frame', to avoid confusion with its global namesake.
3250 2012-10-08 Daniel Colascione <dancol@dancol.org>
3252 * xdisp.c (start_hourglass): Call w32_note_current_window when
3253 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3254 build that caused Emacs to display the hourglass cursor forever.
3256 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3257 which is broken under remote desktop, calculate the number of
3258 colors available for a display based on the display's number of
3259 planes and number of bits per pixel per plane. (bug#10397).
3261 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3263 * nsfont.m (Vfonts_in_cache): New variable.
3264 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3265 are used. Add cached fonts to Vfonts_in_cache.
3266 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3268 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3270 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3272 (FONT_H): Define after FRAME_H.
3273 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3274 Update dependencies.
3276 * w32term.c: Remove leftover declaration of keyboard_codepage.
3278 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3280 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3281 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3282 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3283 (GLOBAL_SOURCES): Add cygw32.c.
3284 ($(BLD)/unexw32.$(O)):
3286 ($(BLD)/w32console.$(O)):
3287 ($(BLD)/w32fns.$(O)):
3288 ($(BLD)/w32heap.$(O)):
3289 ($(BLD)/w32menu.$(O)):
3290 ($(BLD)/w32proc.$(O)): Add w32common.h.
3292 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3294 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3296 2012-10-08 Daniel Colascione <dancol@dancol.org>
3298 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3299 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3300 accidental message numbering hole. Change other messages to
3303 * w32select.h (HAVE_W32SELECT): Remove.
3305 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3306 w32common.h instead of w32heap.h.
3308 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3309 (get_allocation_unit, get_processor_type, get_w32_major_version)
3310 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3311 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3312 (OS_NT, os_subtype, cache_system_info): Move declarations to
3315 * w32heap.c: Include w32common.h.
3316 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3317 (w32_minor_version, w32_build_number, w32_subtype):
3318 Remove duplicate definitions.
3320 * w32fns.c: Include w32common.h; include w32heap.h only in
3323 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3324 Use `report_file_error' instead of `error' in order to better
3325 inform users of what went wrong. Increase NTGUI_UNICODE file
3326 dialog box file name length to 32k, the maximum allowed by the NT
3329 * w32common.h: New file.
3330 (ROUND_UP, ROUND_DOWN, get_page_size)
3331 (get_allocation_unit, get_processor_type, get_w32_major_version)
3332 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3333 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3334 (OS_NT, os_subtype, cache_system_info): Move here.
3336 * unexw32.c, unexcw.c: Include w32common.h.
3338 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3339 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3340 to call syms_of_w32select.
3342 * cygw32.h: Remove obsolete EXFUN declarations.
3344 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3346 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3347 of w32inevt.o from SOME_MACHINE_OBJECTS.
3349 2012-10-08 Daniel Colascione <dancol@dancol.org>
3351 * image.c: Permanent fix for JPEG compilation issue --- limit
3352 jpeglib `boolean' redefinition to Cygwin builds.
3354 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3356 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3358 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3361 2012-10-08 Daniel Colascione <dancol@dancol.org>
3363 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3364 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3365 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3366 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3367 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3368 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3369 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3370 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3371 now a supported configuration.
3373 * Makefile.in: consolidate image variables into LIBIMAGE; add
3374 W32_OBJ and W32_LIBS. Compile new files.
3377 (_DebPrint) declare tracing facility for W32 debugging. We need
3378 to unify tracing later.
3380 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3381 unconditional use of W32 Unicode functions. Cygwin runs only on
3382 100% Unicode operating systems.
3384 * cygw32.c: New file. Define Cygwin-specific facilities.
3385 (Fcygwin_convert_path_to_windows)
3386 (Fcygwin_convert_path_from_windows): New user functions for
3387 accessing Cygwin path-munging routines.
3389 * cygw32.h: New file.
3390 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3391 UTF-16LE strings temporarily inside non-Lisp-visible string
3394 (w32_strerror): Just what it says on the tin.
3396 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3397 also run for Cygwin; both systems have the same problem with using
3398 GUI facilities in a forked child. Also call syms_of_cygw32,
3399 syms_of_w32select in correct places.
3401 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3402 needs fork-then-exec for daemon launching.
3404 * font.h: Include frame.h.
3406 * image.c: Use the image library cache machinery only when we're
3407 compiling for native WINDOWSNT; Cygwin can use shared libraries
3408 like any other Unixlike system.
3410 * keyboard.c: Clarify a comment regarding the input loop.
3412 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3413 functions directly instead of trying to detect at runtime that our
3414 host operating system supports them. We make this change for two
3415 reasons: Cygwin lacks support for the multibyte character
3416 conversion functions used by the legacy menu code, and Cygwin
3417 never needs to rely on non-Unicode APIs.
3419 * unexw32.c (hinst): Declare extern.
3421 * w32.c: Change header order;
3422 (w32_strerror): Move to w32fns.c because we need it for
3423 non-WINDOWSNT builds.
3425 * w32.h: Add #error macro to make sure we don't include w32.h for
3426 Cygwin builds. Remove w32select declarations.
3428 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3429 w32fns.c. w32console.c is WINDOWSNT-only.
3431 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3432 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3434 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3435 (w32_major_version, w32_minor_version, w32_build_number)
3436 (os_subtype, sound_type): Define here
3437 (w32_defined_color): Make color parameter const for consistency
3438 with other _defined_color functions.
3439 (w32_createwindow): Unconditionally call w32_init_class instead of
3440 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3441 through the code is complex and unnecessary because class
3442 registration is practically free.
3443 (w32_name_of_message): New EMACSDEBUG-only function.
3444 (Fset_message_beep): Move here
3445 (Fx_open_connection): Require that the display name for Windows be
3446 "w32" for consistency, emacsclient disambiguation, and maybe, one
3447 day, multi-window-system support.
3448 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3449 Cygwin files for W32 GUI facilities, since these clearly don't
3450 expect Cygwin names.
3451 (_DebPrint): Define.
3452 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3453 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3454 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3455 (w32_last_error): Remove.
3457 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3459 * w32heap.c (syspage_mask): Declare here.
3460 (cache_system_info): Remove.
3462 * w32inevt.c (faked_key): Define globally, not statically.
3463 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3464 (w32_console_toggle_lock_key): Move to w32fns.c.
3466 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3468 * w32proc.c (_DebPrint): Move to w32fns.c.
3469 * w32select.c: Include string.h, stdio.h for Cygwin.
3470 * w32select.h: New File.
3472 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3474 (w32_message_fd): New variable. Under Cygwin, holds the file
3475 descriptor the system used to tell us about pending thread
3478 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3479 that prevented compilation under non-WINDOWSNT systems.
3481 (w32_initialize): Open /dev/windows and assign it to
3482 w32_message_fd. Provide w32 feature.
3484 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3485 (WM_EMACS_INPUT_READY): add.
3486 (prepend_msg, w32_message_fd): Declare globally.
3489 (keyboard_handle): Use only when WINDOWSNT.
3490 (notify_msg_ready): New function. Posts a message to the main
3491 thread's message queue under CYGWIN, which wakes up the main
3492 thread from select(2) by making the /dev/windows file descriptor
3493 ready. Under WINDOWSNT, it sets an event the same way the old
3496 (post, prepend_msg): Actually call notify_msg_ready instead of
3497 setting the input event directly.
3499 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3501 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3502 but it still has blocs in it, don't return it to the system,
3503 instead of aborting. (Bug#12402)
3505 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3507 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3509 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3510 MAC_OS_X_VERSION_10_6.
3511 (syms_of_nsterm): Remove comment about Panther and above for
3513 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3514 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3515 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3517 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3518 MAC_OS_X_VERSION_10_4.
3520 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3521 MAC_OS_X_VERSION_10_2.
3523 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3525 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3526 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3528 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3529 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3530 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3531 Remove ns_in_resize check.
3532 (ns_clear_frame_area): Remove resize handle code.
3534 * nsfns.m (ns_in_resize): Remove.
3535 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3536 Remove ns_in_resize check.
3538 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3540 Improve sys_siglist detection.
3541 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3542 defined as a macro, as is done in Solaris.
3543 (sys_siglist_entries): New macro.
3544 (save_strsignal): Use it.
3545 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3546 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3548 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3550 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3551 fullscreen/Fullscreen.
3553 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3554 tobar_height is new.
3556 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3557 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3558 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3559 (windowDidResize:): Check for correct window if old style fullscreen.
3560 Capitalize word in comment. Remove incorrect comment.
3561 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3562 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3563 error in drawing background.
3564 (toggleFullScreen:): Remove comment. Rearrange calls.
3565 Set toolbar values to zero, save old height in tobar_height.
3566 Restore tool bar height when leaving fullscreen.
3567 (canBecomeMainWindow): New function.
3569 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3571 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3573 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3575 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3577 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3578 that time stamps of directories could also be changed.
3579 Don't request the too broad GENERIC_WRITE, only the more restrictive
3580 FILE_WRITE_ATTRIBUTES access rights.
3582 * fileio.c (Fset_file_times): Special-case ignoring errors for
3583 directories only on MSDOS, not on MS-Windows.
3585 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3587 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3589 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3591 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3592 see whether CreateFile failed.
3594 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3596 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3597 to avoid similar races.
3598 * keyboard.c (pending_signals): Now bool, not int.
3600 Port timers to OpenBSD, plus check for timer failures.
3601 OpenBSD problem reported by Han Boetes.
3602 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3604 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3605 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3606 like OpenBSD, which has timer_settime but does not declare it.
3607 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3608 whether to use itimerspec-related primitives. All uses of
3609 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3611 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3613 * profiler.c (handle_profiler_signal): Fix a malloc race
3614 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3616 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3618 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3620 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3622 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3623 consistent with the change in return value of 'safe_strsignal'.
3625 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3627 Prefer plain 'static' to 'static inline' (Bug#12541).
3628 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3629 (bidi_set_sor_type, bidi_push_embedding_level)
3630 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3631 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3632 (bidi_cache_search, bidi_cache_ensure_space)
3633 (bidi_cache_iterator_state, bidi_cache_find)
3634 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3635 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3636 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3637 Now 'static', not 'static inline'.
3639 Count overruns when profiling; change units to ns.
3640 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3641 Give extra weight to samples after overruns, to attempt to count
3642 the time more accurately.
3643 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3644 the underlying primitives nominally do ns.
3645 (Fprofiler_cpu_start): Document the change. Mention that
3646 the sampling intervals are only approximate.
3648 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3650 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3652 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3653 case for the special 0 coding-system.
3655 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3656 (Fmake_overlay): Remove redundant tests.
3657 (fix_start_end_in_overlays): Remove redundant recentering.
3659 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3661 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3662 Update dependencies.
3664 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3666 Fix a malloc race condition involving strsignal.
3667 A signal can arrive in the middle of a malloc, and Emacs's signal
3668 handler can invoke strsignal, which can invoke malloc, which is
3669 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3670 Fix it by altering the signal handler so that it does not invoke
3672 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3673 * process.c (status_message): Use const pointer, in case strsignal
3674 is #defined to safe_strsignal.
3675 * sysdep.c (sys_siglist, init_signals): Always define and
3676 initialize a substitute sys_siglist if the system does not define
3677 one, even if HAVE_STRSIGNAL.
3678 (safe_strsignal): Rename from strsignal. Always define,
3679 using sys_siglist. Return a const pointer.
3680 * syssignal.h (safe_strsignal): New decl.
3681 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3683 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3685 * w32proc.c (timer_loop): Fix code that waits for timer
3686 expiration, to avoid high CPU usage.
3688 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3690 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3691 (sweep_weak_table): Remove redundant prototypes.
3693 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3695 * emacs.c: Move the inclusion of TERM_HEADER after including
3696 windows.h on WINDOWSNT. This avoids compilation problems with
3699 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3701 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3702 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3703 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3704 as the previous version used 'void *'.
3706 * ralloc.c (ROUNDUP): Fix last change.
3707 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3710 * w32proc.c <disable_itimers>: New static flag.
3711 (init_timers): Initialize it to zero, after creating the critical
3712 sections used by the timer threads.
3713 (term_timers): Set to 1 before deleting the critical sections.
3714 (getitimer, setitimer): If disable_itimers is non-zero, return an
3715 error indication without doing anything. Reported by Fabrice
3716 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3717 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3719 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3722 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3723 term_ntproc after all the other bookkeeping, to get timers working
3724 as long as possible.
3726 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3728 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3729 Suggested by Juri Linkov in
3730 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3732 Prefer plain 'static' to 'static inline' (Bug#12541).
3733 With static functions, modern compilers inline pretty well by
3734 themselves; advice from programmers often hurts as much as it helps.
3735 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3736 this change shrinks the text size of the Emacs executable by 1.1%
3737 without affecting CPU significantly in my benchmark.

4110 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4111 Since this stuff is now private to charset.c, there's no need for
4112 a public macro and no need to inline by hand.

4173 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
4174 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
4176 * w32.h (Vlibrary_cache): Do not declare.
4178 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4180 * w32proc.c (sys_signal): Handle all signals defined by the
4181 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4182 handlers for signals supported by Windows. Don't override
4183 term_ntproc as the handler for SIGABRT.
4184 (sigaction): Rewrite to call sys_signal instead of duplicating its
4186 (sys_kill): Improve commentary.
4188 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4189 consistency with a signature of a signal handler. All callers
4191 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4192 install term_ntproc as a signal handler for SIGABRT, as that
4193 should be done by the dumped Emacs.
4195 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4197 * w32select.c (term_w32select): Protect against repeated
4198 invocation by setting clipboard_owner to NULL after calling
4201 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
4202 and term_ntproc to their modified signatures.
4204 * character.c (char_string, string_char): Remove calls to
4205 MAYBE_UNIFY_CHAR. See the discussion starting at
4206 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
4209 2012-09-25 Chong Yidong <cyd@gnu.org>
4211 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4213 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4215 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4216 when encountering an unknown bytecode.
4218 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4220 image.c, indent.c: Use bool for booleans.
4221 * dispextern.h (struct image_type): Members valid_p, load, init
4222 now return bool, not int. All uses changed.
4223 * image.c: Omit unnecessary static decls.
4224 (x_create_bitmap_mask, x_build_heuristic_mask):
4225 Return void, not int, since callers don't care about the return value.

4256 2012-09-24 Chong Yidong <cyd@gnu.org>
4258 * chartab.c (Fset_char_table_default): Obsolete function removed.
4260 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4262 Move pid_t related decls out of lisp.h.
4263 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4264 (interruptible_wait_for_termination):
4265 Move these decls from lisp.h to syswait.h, since they use pid_t.
4266 Needed on FreeBSD; see Herbert J. Skuhra in
4267 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4268 * callproc.c: Include syswait.h.

4286 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
4287 * xfns.c (Fx_show_tip) [USE_GTK]:
4288 Use bool for boolean.
4289 * gtkutil.c (xg_update_frame_menubar):
4290 * xmenu.c (update_frame_menubar):
4291 Return void, not int, since caller ignores return value.
4292 * gtkutil.c (xg_change_toolbar_position):
4295 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4297 * makefile.w32-in (BLOCKINPUT_H): Remove.

4314 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4316 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4317 fatal_error_backtrace.
4319 * w32proc.c (sys_kill): Undo last change: don't do anything when
4320 invoked to deliver SIGABRT to our own process. This is now
4321 handled by emacs_raise.
4323 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4325 * w32term.c (w32_read_socket): Remove leftover reference to
4326 interrupt_input_pending.
4328 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4330 Do not use SA_NODEFER.
4331 Problem reported by Dani Moncayo in
4332 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4334 * sysdep.c (emacs_abort): Do not reset signal handler.
4335 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4336 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4337 wanted even on POSIXish hosts, and it doesn't work on Windows.
4339 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4341 * xterm.c (x_term_init): Call fixup_locale before and after calling
4342 gtk_init (Bug#12392).
4344 2012-09-23 Chong Yidong <cyd@gnu.org>
4346 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4347 Vdynamic_library_alist.
4349 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4350 (Fgnutls_available_p): Caller changed.
4352 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4353 (Flibxml_parse_xml_region): Likewise.
4355 * dispextern.h (struct image_type): Remove arg from init function.
4357 * image.c (Finit_image_library, lookup_image_type)
4358 (define_image_type): Remove now-unneeded second arg.
4359 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4360 (init_tiff_functions, init_gif_functions, init_svg_functions):
4361 Arglist and w32_delayed_load calling convention changed.
4362 (gs_type): Remove init_gs_functions; there is no such function.
4363 (valid_image_p, make_image): Fix caller to lookup_image_type.
4365 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4367 Simplify and avoid signal-handling races (Bug#12471).
4369 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4370 Avoid recursive loop if there's a fatal error in the function itself.
4371 * atimer.c (pending_atimers):
4372 * blockinput.h: Don't include "atimer.h"; no longer needed.
4373 (interrupt_input_pending): Remove. All uses removed.
4374 pending_signals now counts both atimers and ordinary interrupts.
4375 This is less racy than having three separate pending-signal flags.
4376 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4378 Rename from their upper-case counterparts BLOCK_INPUT,
4379 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4380 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4381 This makes it easier to access volatile variables more accurately.
4382 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4383 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4384 that's more reliable if the code is buggy and sets
4385 interrupt_input_blocked to a negative value. All uses changed.
4386 * atimer.c (deliver_alarm_signal):
4387 Remove. No need to deliver this to the parent; any thread can
4388 handle this signal now. All uses replaced by underlying handler.
4389 * atimer.c (turn_on_atimers):
4390 * dispnew.c (handle_window_change_signal):
4391 * emacs.c (handle_danger_signal):
4392 * keyboard.c (kbd_buffer_get_event):
4393 Don't reestablish signal handler; not needed with sigaction.
4394 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4396 Rework to avoid unnecessary accesses to volatile variables.
4397 (UNBLOCK_INPUT_TO): Now a function.
4398 (totally_unblock_input, unblock_input): New decls.
4399 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4400 (init_data): Remove. Necessary stuff now done in init_signal.
4401 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4402 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4403 (fatal_error_code): Remove; no longer needed.
4404 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4405 it doesn't always backtrace. All uses changed. No need to reset
4406 signal to default, since sigaction and/or die does that for us now.
4407 Use emacs_raise (FOO), not kill (getpid (), FOO).
4408 (main): Check more-accurately whether we're dumping.
4409 Move fatal-error setup to sysdep.c
4410 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4411 * gtkutil.c (xg_get_file_name, xg_get_font):
4412 Remove no-longer-needed signal-mask manipulation.
4413 * keyboard.c, process.c (POLL_FOR_INPUT):
4414 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4415 * keyboard.c (read_avail_input): Remove.
4416 All uses replaced by gobble_input.
4417 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4418 (kbd_buffer_store_event_hold, gobble_input):
4419 (record_asynch_buffer_change) [USABLE_SIGIO]:
4420 (store_user_signal_events):
4421 No need to mess with signal mask.
4422 (gobble_input): If blocking input and there are terminals, simply
4423 set pending_signals to 1 and return. All hooks changed to not
4424 worry about whether input is blocked.
4425 (process_pending_signals): Clear pending_signals before processing
4426 them, in case a signal comes in while we're processing.
4427 By convention callers now test pending_signals before calling us.
4428 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4429 New functions, to support changes to blockinput.h.
4430 (handle_input_available_signal): Now extern.
4431 (reinvoke_input_signal): Remove. All uses replaced by
4433 (quit_count): Now volatile, since a signal handler uses it.
4434 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4435 All callers changed. Block SIGINT only if not already blocked.
4436 Clear sigmask reliably, even if Fsignal returns, which it can.
4437 Omit unnecessary accesses to volatile var.
4438 (quit_throw_to_read_char): No need to restore sigmask.
4439 * keyboard.c (gobble_input, handle_user_signal):
4440 * process.c (wait_reading_process_output):
4441 Call signal-handling code rather than killing ourselves.
4442 * lisp.h: Include <float.h>, for...
4443 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4444 (pending_signals): Now volatile.
4445 (syms_of_data): Now const if IEEE floating point.
4446 (handle_input_available_signal) [USABLE_SIGIO]:
4447 (terminate_due_to_signal, record_child_status_change): New decls.
4448 * process.c (create_process): Avoid disaster if memory is exhausted
4449 while we're processing a vfork, by tightening the critical section
4451 (send_process_frame, process_sent_to, handle_pipe_signal)
4452 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4454 (send_process): No need for setjmp/longjmp any more, since the
4455 SIGPIPE stuff is now gone. Instead, report an error if errno
4457 (record_child_status_change): Now extern. PID and W are now args.
4458 Return void, not bool. All callers changed.
4459 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4460 Remove. All uses removed. This bug should be fixed now in a
4462 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4463 and record the child status change directly. This avoids the
4464 need to futz with the signal mask.
4465 (process_fatal_action): Move here from emacs.c.
4466 (emacs_sigaction_flags): New function, containing
4467 much of what used to be in emacs_sigaction_init.
4468 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4469 caught by emacs, to make races less likely.
4470 (deliver_process_signal): Rename from handle_on_main_thread.
4472 (BACKTRACE_LIMIT_MAX): Now at top level.
4473 (thread_backtrace_buffer, threadback_backtrace_pointers):
4475 (deliver_thread_signal, deliver_fatal_thread_signal):
4476 New functions, for more-accurate delivery of thread-specific signals.
4477 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4478 (deliver_arith_signal): Handle in this thread, not
4479 in the main thread, since it's triggered by this thread.
4480 (maybe_fatal_sig): New function.
4481 (init_signals): New arg DUMPING so that we can be more accurate
4482 about whether we're dumping. Caller changed.
4483 Treat thread-specific signals differently from process-general signals.
4484 Block all signals while handling fatal error; that's safer.
4485 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4487 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4488 Ignore SIGPIPE unless batch.
4489 (emacs_backtrace): Output backtrace for the appropriate thread,
4490 which is not necessarily the main thread.
4491 * syssignal.h: Include <stdbool.h>.
4492 (emacs_raise): New macro.
4493 * xterm.c (x_connection_signal): Remove; no longer needed
4494 now that we use sigaction.
4495 (x_connection_closed): No need to mess with sigmask now.
4496 (x_initialize): No need to reset SIGPIPE handler here, since
4497 init_signals does this for us now.
4499 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4501 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4502 background rect may be larger (Bug#12245).
4504 2012-09-23 Chong Yidong <cyd@gnu.org>
4506 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4508 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4510 * .gdbinit: Just stop at fatal_error_backtrace.
4511 See Stefan Monnier's request in
4512 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4513 Remove no-longer-used query of system type.
4515 2012-09-22 Chong Yidong <cyd@gnu.org>
4517 * search.c (Freplace_match): Doc fix (Bug#12325).
4519 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4521 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4522 (Fline_end_position): Doc fix.
4524 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4526 2012-09-22 Chong Yidong <cyd@gnu.org>
4528 * dispextern.h (struct image_type): Add new slot, storing a type
4529 initialization function.
4531 * image.c (define_image_type): Call the image initializer function
4532 if it is defined. Arguments and return value changed.
4533 (valid_image_p, make_image): Callers changed.
4534 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4535 (gif_type, imagemagick_type, svg_type, gs_type):
4536 Add initialization functions.
4537 (Finit_image_library): Call lookup_image_type.
4538 (CHECK_LIB_AVAILABLE): Macro deleted.
4539 (lookup_image_type): Call define_image_type here, rather than via
4540 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4541 (syms_of_image): Move define_image_type calls for xbm_type and
4542 pbm_type to lookup_image_type.
4544 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4546 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4547 'idle_timers' from here ...
4548 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4549 lists, to avoid infloops when the timer does something stupid,
4550 like reinvoke itself with the same or smaller time-out.
4553 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4555 * window.c (Fsplit_window_internal): Handle only Qt value of
4556 Vwindow_combination_limit separately.
4557 (Qtemp_buffer_resize): New symbol.
4558 (Vwindow_combination_limit): New default value.
4561 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4563 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4564 the new overlay string. (Bug#10159)
4566 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4568 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4569 or that fprintf is async-signal-safe. POSIX doesn't require
4572 2012-09-22 Chong Yidong <cyd@gnu.org>
4574 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4577 2012-09-22 Kenichi Handa <handa@gnu.org>
4579 * composite.c (composition_reseat_it): Handle the case that a
4580 grapheme cluster is not covered by a single font (Bug#12352).
4582 2012-09-21 Chong Yidong <cyd@gnu.org>
4584 * image.c (define_image_type): Avoid adding duplicate types to
4585 image_types (Bug#12463). Suggested by Jörg Walter.
4587 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4589 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4590 (print_load_command_name): Add case LC_DATA_IN_CODE.
4591 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4593 2012-09-21 Glenn Morris <rgm@gnu.org>
4595 * eval.c (Frun_hook_with_args_until_success)
4596 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4598 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4600 * fileio.c (Ffile_selinux_context): Only call freecon when
4601 lgetfilecon succeeded.
4602 (Fset_file_selinux_context): Likewise. (Bug#12444)
4604 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4606 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4607 reordering, locate the cursor by calling set_cursor_from_row; if
4608 that fails, clear the desired glyph matrix before returning a
4609 failure indication to the caller. Fixes leaving garbled display
4610 when fast scrolling with a down-key. (Bug#12403)
4611 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4612 scrolling through multibyte text.
4614 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4616 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4617 calling mark_vectorlike since that's the one that marks the window.
4618 (mark_discard_killed_buffers): Mark the final cdr.
4619 * window.h (struct window): Move prev/next_buffers to the
4620 non-standard fields.
4621 * window.c (make_window): Initialize prev/next_buffers manually.
4623 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4625 Omit unused arg EXPECTED from socket hooks.
4626 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4627 * nsterm.m (ns_term_init):
4628 * termhooks.h (struct terminal.read_socket_hook):
4629 * w32inevt.c (w32_console_read_socket):
4630 * w32term.c (w32_read_socket):
4631 * xterm.c (XTread_socket):
4632 Omit unused arg EXPECTED. All callers changed.
4633 (store_user_signal_events): Return void, not int, since callers no
4634 longer care about the return value. All uses changed.
4636 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4638 * w32gui.h (XParseGeometry): Do not declare.
4640 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4642 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4643 Ignore 'expected'. See Eli Zaretskii in
4644 <http://bugs.gnu.org/12471#8> (last line).
4646 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4647 (XParseGeometry): Now static. Substitute extremal values for
4648 values that are out of range.
4650 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4652 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4654 * nsfns.m (XParseGeometry): Remove.
4655 (Fx_create_frame): Call x_set_offset to correctly interpret
4656 top_pos in geometry.
4658 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4659 (Fx_parse_geometry): If there is a space in string, call
4660 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4662 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4664 * search.c (scan_buffer): Use character positions in calls to
4665 region_cache_forward and region_cache_backward, not byte
4666 positions. (Bug#12196)
4668 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4669 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4671 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4672 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4673 emacs_blocked_malloc, now deleted.
4675 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4677 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4678 The workaround was for improving performance on Solaris 2.4, but
4679 is getting in the way now. Emacs will still work if someone is
4680 still running Solaris 2.4 in a museum somewhere; Sun dropped
4681 support for Solaris 2.4 in 2003.
4682 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4683 * process.c (create_process) [HAVE_WORKING_VFORK]:
4684 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4685 since Emacs no longer uses vfork on that platform.
4687 2012-09-17 Glenn Morris <rgm@gnu.org>
4689 * emacs.c: Use COPYRIGHT.
4691 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4693 Remove configure's --without-sync-input option (Bug#12450).
4694 When auditing signal-handling in preparation for cleaning it up,
4695 I found that SYNC_INPUT has race conditions and would be a real
4696 pain to fix. Since it's an undocumented and deprecated
4697 configure-time option, now seems like a good time to remove it.
4698 Also see <http://bugs.gnu.org/11080#16>.
4699 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4700 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4701 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4702 (malloc_hysteresis):
4703 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4704 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4705 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4706 (dont_register_blocks, bytes_used_when_reconsidered)
4707 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4708 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4709 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4710 Remove. All uses removed.
4711 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4712 implementation, one that depends on whether the new macro
4713 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4715 * atimer.c (run_timers, handle_alarm_signal):
4716 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4717 (handle_async_input, process_pending_signals)
4718 (handle_input_available_signal, init_keyboard):
4719 * nsterm.m (ns_read_socket):
4720 * process.c (wait_reading_process_output):
4721 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4722 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4724 * xterm.c (XTread_socket):
4726 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4727 * eval.c (handling_signal): Remove. All uses removed.
4728 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4729 All uses replaced with the SYNC_INPUT version.
4730 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4732 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4735 * font.c (Ffont_shape_gstring): Remove unused local.
4737 2012-09-16 Glenn Morris <rgm@gnu.org>
4739 * Makefile.in (clean): No longer run nextstep's clean.
4741 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4743 (ns-app): Move here from ns.mk, and simplify.
4744 (clean): Simplify nextstep entry.
4745 * ns.mk: Remove file.
4747 2012-09-17 Kenichi Handa <handa@gnu.org>
4749 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4750 not covert the last few charactes.
4752 2012-09-16 Kenichi Handa <handa@gnu.org>
4754 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4755 here, but just check the validity of glyphs in the glyph-string.
4757 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4759 * window.c (Fwindow_parameter, Fset_window_parameter):
4760 Accept any window as argument (Bug#12452).
4762 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4764 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4765 to ns_term_init to avoid memory leak.
4767 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4768 explicit retain/release.
4769 (ns_term_init): Only allow one display. Initialize outerpool and
4772 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4774 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4775 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4776 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4777 the Microsoft problem in a different way, by altering ../nt/config.nt.
4779 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4794 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4795 by lisp.h. This completes removal of setjmp.h inclusion
4796 erroneously announced in the previous commit. (Bug#12446)
4798 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4801 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4802 not defined as a macro. The latter happens on MS-Windows.
4805 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4807 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4808 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4809 Some instances of '#include <setjmp.h>' removed, if the
4810 only reason for the instance was because "lisp.h" was included.
4811 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4812 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4813 and _longjmp with the new symbols. Emacs already uses _setjmp if
4814 available, so this change affects only POSIXish hosts that have
4815 sigsetjmp but not _setjmp, such as some versions of Solaris and
4816 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4817 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4818 (png_load_body) [HAVE_PNG]:
4819 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4820 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4821 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4822 since PNG requires jmp_buf. This is the only exception to the
4823 general rule that we now use sys_setjmp and sys_longjmp.
4824 This exception is OK since this code does not change the signal
4825 mask or longjmp out of a signal handler.
4827 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4829 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4830 Include "syssignal.h", for 'main_thread'.
4832 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4834 Avoid out-of-range marker position (Bug#12426).
4835 * insdel.c (replace_range, replace_range_2):
4836 Adjust markers before overlays, as suggested by comments.
4837 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4838 Remove redundant check before calling offset_intervals.
4840 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4842 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4843 current buffer (Bug#12387).
4845 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4847 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4849 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4851 Use a more backwards-compatible timer format (Bug#12430).
4852 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4853 vector element, not from the 4th, since PSECS is now at the end.
4854 (Fcurrent_idle_time): Doc fix.
4856 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4858 Function to mark objects and remove killed buffers at once.
4859 * alloc.c (discard_killed_buffers): Rename to ...
4860 (mark_discard_killed buffers) ... new name. Add marking
4861 of remaining objects. Fix comment. Adjust users.
4862 (mark_object): Do not touch frame buffer lists here.
4863 * frame.c (delete_frame): Reset frame buffer lists here.
4865 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4867 Better workaround for GNOME bug when --enable-gcc-warnings.
4868 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4869 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4870 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4872 Simplify SIGIO usage (Bug#12408).
4873 The code that dealt with SIGIO was crufty and confusing, e.g., it
4874 played tricks like "#undef SIGIO" but these tricks were not used
4875 consistently. Simplify mostly by not #undeffing standard symbols,
4876 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4877 or not as we please) rather than "defined SIGIO" (standard symbol
4878 that we probably shouldn't #undef).
4879 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4880 Modules that need it can include it.
4881 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4882 * dispextern.h (ignore_sigio): New decl.
4883 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4884 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4885 * emacs.c (shut_down_emacs):
4886 * keyboard.c (kbd_buffer_store_event_hold):
4887 Use ignore_sigio rather than invoking 'signal' directly.
4888 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4890 (FIONREAD, SIGIO): Do not #undef.
4891 (tty_read_avail_input): Use #error rather than a syntax error.
4892 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4893 for I_PIPE, used by SETUP_SLAVE_PTY.
4894 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4895 * sysdep.c (croak): Remove; no longer needed. This bit of
4896 temporary code, with Fred N. Fish's comment that it's temporary,
4897 has been in Emacs since at least 1992!
4898 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4899 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4900 * syssignal.h (croak): Remove decl.
4901 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4902 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4903 now that we're termios-only.
4904 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4905 * term.c (dissociate_if_controlling_tty): Use #error rather than
4908 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4909 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4910 to work around GNOME bug 683906.
4911 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4912 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4913 This works around GCC bug 54561.
4915 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4917 More fixes for 'volatile' and setjmp/longjmp.
4918 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4919 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4920 (png_load_body) [HAVE_PNG]:
4921 (jpeg_load_body) [HAVE_JPEG]:
4922 New function, with most of the old parent function's body.
4923 (png_load) [HAVE_PNG]:
4924 (jpeg_load) [HAVE_JPEG]:
4925 Invoke the new function, to avoid longjmp munging our locals.
4926 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4927 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4928 longjmp is passed 2, as the C standard doesn't guarantee this.
4929 Instead, store the failure code into mgr->failure_code.
4931 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4933 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4934 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4935 (syms_of_keyboard): Remove support for unread-command-char.
4937 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4939 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4940 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4941 violation. (Bug#12426)
4943 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4945 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4947 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4949 * eval.c: Add `inhibit-debugger'.
4950 (Qinhibit_debugger): New symbol.
4951 (call_debugger): Bind it instead of Qdebug_on_error.
4952 (maybe_call_debugger): Test Vinhibit_debugger.
4953 (syms_of_eval): Define inhibit-debugger.
4954 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4955 (syms_of_xdisp): Remove inhibit-debug-on-message.
4957 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4959 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4960 If a nonvolatile local variable is written before a _longjmp to
4961 the frame containing the variable, and is read after the _longjmp,
4962 the value read is indeterminate. Some local variables of type
4963 'struct handler' and 'struct catchtag' are used in this way, so
4964 mark each of their slots as volatile if the slot can be set before
4965 _longjmp and read afterwards.
4966 * lisp.h (struct handler): var and chosen_clause are now volatile.
4967 (struct catchtag): val, next, and pdlcount are now volatile.
4969 * bidi.c (bidi_push_it, bidi_pop_it):
4970 * fns.c (copy_hash_table):
4971 * image.c (define_image_type):
4972 * keyboard.c (kbd_buffer_store_event_hold):
4973 * process.c (Fprocess_send_eof):
4974 * xfaces.c (x_create_gc) [HAVE_NS]:
4975 * xgselect.c (xg_select):
4976 Prefer assignment to memcpy when either will do.
4978 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4979 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4980 time an item is removed. No need to mark this function 'inline';
4981 the compiler knows better than we do.
4983 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4985 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4986 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4987 to change_frame_size (Bug#12388).
4988 (windowDidResize:): Pass YES to updateFrameSize.
4990 * nsterm.h: Add delay parameter to updateFrameSize.
4992 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4994 Discard killed buffers from deleted window and frame objects.
4995 This reduces an amount of references to killed buffers and
4996 helps GC to reclaim them faster.
4997 * alloc.c (discard_killed_buffers): New function.
4998 (mark_object): Use it for deleted windows and frames.
4999 (mark_object): If symbol's value is set up for a killed buffer
5000 or deleted frame, restore its global binding.
5001 * data.c (swap_in_global_binding): Add GC notice.
5002 (swap_in_symval_forwarding): Use convenient set_blv_where.
5003 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5004 * window.h: ... to here.
5006 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5008 Convenient macro to check whether the buffer is live.
5009 * buffer.h (BUFFER_LIVE_P): New macro.
5010 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5011 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5013 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5015 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5016 composition cases (Bug#12364).
5018 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5019 overhang of succeeding glyphs overlapping box cursor.
5021 * w32term.c (x_draw_glyph_string): Likewise.
5023 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5025 Simplify, document, and port floating-point (Bug#12381).
5026 The porting part of this patch fixes bugs on non-IEEE platforms
5027 with frexp, ldexp, logb.
5028 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5030 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5031 support, by removing commented-out code and briefly listing the
5032 C89 functions excluded. The commented-out stuff was confusing
5033 maintenance, e.g., we thought we needed cbrt but it was commented out.
5034 (logb): Remove decl; no longer needed.
5035 (isfinite): New macro, if not already supplied.
5036 (isnan): Don't replace any existing macro.
5037 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5038 are present on all C89 platforms.
5039 (Ffrexp): Do not special-case zero, as frexp does the right thing
5041 (Flogb): Do not use logb, as it doesn't have the desired meaning
5042 on hosts that use non-base-2 floating point. Instead, stick with
5043 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5044 frexp, to avoid getting an unspecified result.
5046 * xdisp.c (Qinhibit_debug_on_message): Now static.
5048 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5050 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5051 NSBezierPath (Bug#12131).
5053 2012-09-10 Chong Yidong <cyd@gnu.org>
5055 * fns.c (Fdelq, Fdelete): Doc fix.
5057 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5059 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5060 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5062 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5064 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5065 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5068 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5070 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5071 left fringe if the window has a left margin. This avoids leaving
5072 traces of the cursor because its leftmost pixel is not drawn over.
5074 * dispnew.c (update_window_line): When the left margin area of a
5075 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5076 that screen line. (Bug#12277)
5078 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5080 Assume C89 or later for math functions (Bug#12381).
5081 This simplifies the code, and makes it a bit smaller and faster,
5082 and (most important) makes it easier to clean up signal handling
5083 since we can stop worring about floating-point exceptions in
5084 library code. That was a problem before C89, but the problem
5085 went away many years ago on all practical Emacs targets.
5086 * data.c, image.c, lread.c, print.c:
5087 Don't include <math.h>; no longer needed.
5088 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5089 might be autoconfigured, as that never happens.
5091 * doprnt.c (DBL_MAX_10_EXP):
5092 * print.c (DBL_DIG):
5093 Remove. C89 or later always defines these.
5094 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5095 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5096 (arith_error, domain_error, domain_error2):
5097 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5098 no longer needed -- we simply return what C returns. All uses removed.
5099 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5101 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5102 Remove. All uses expanded, as these macros are no longer used
5103 more than once and are now more trouble than they're worth.
5104 (Ftan): Use tan, not sin / cos.
5105 (Flogb): Assume C89 frexp.
5106 (fmod_float): Assume C89 fmod.
5107 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5108 (init_floatfns): Remove. All uses removed.
5110 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5112 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5113 compositeToPoint for OSX < 10.6 (Bug#12390).
5115 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5117 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5118 This produces more-accurate results.
5120 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5122 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5123 changes (Bug#12088).
5125 2012-09-08 Chong Yidong <cyd@gnu.org>
5127 * syntax.c (Fstring_to_syntax): Doc fix.
5129 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5131 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5132 in the internal border.
5133 (x_set_window_size): Remove static variables and their usage.
5134 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5135 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5136 Remove fringe/internal border adjustment (Bug#11052).
5137 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5138 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5139 (ns_fix_rect_ibw): Remove.
5140 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5141 (ns_dumpglyphs_box_or_relief): Ditto.
5142 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5144 (ns_dumpglyphs_image): Ditto.
5145 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5147 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5148 their usage. Add fringe_extended_p and its use as in other terms.
5149 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5150 scroll bar was removed.
5151 (updateFrameSize): New function.
5152 (windowDidResize): Move code to updateFrameSize and call it.
5154 * nsterm.h (EmacsView): Add updateFrameSize.
5156 2012-09-07 Chong Yidong <cyd@gnu.org>
5158 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5160 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5162 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5164 More signal-handler cleanup (Bug#12327).
5165 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5166 Problem introduced when merging patches. Noted by Eli Zaretskii in
5167 <http://bugs.gnu.org/12327#67>.
5168 * floatfns.c: Comment fix.
5169 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5170 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5171 and anyway the declaration is harmless even if SIGDANGER is not defined.
5172 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5173 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5174 source files not surprisingly expected syssignal.h to define, or
5175 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5176 Include <sys/ioctl.h>, for FIONREAD.
5177 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5178 This eliminates a problem whereby other files mysteriously had
5179 to include "syssignal.h" before including "systty.h" if they
5180 wanted to use "#ifdef SIGIO".
5182 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5184 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5186 * w32.c (sigemptyset): Empty the set.
5187 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5189 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5191 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5193 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5194 (mark_object): Likewise for frame objects.
5196 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5198 * syssignal.h (handle_on_main_thread): Always declare,
5199 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5200 This ports to platforms without HAVE_PTHREAD.
5202 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5204 Signal-handler cleanup (Bug#12327).
5205 Emacs's signal handlers were written in the old 4.2BSD style with
5206 sigblock and sigmask and so forth, and this led to some
5207 inefficiencies and confusion. Rewrite these to use
5208 pthread_sigmask etc. without copying signal sets around. Also,
5209 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5210 'signal', and instead use functions that do not attempt to take
5211 over the system name space. This patch causes Emacs's text
5212 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5213 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5214 Do not include <signal.h> or "syssignal.h", as these
5215 modules do not use signals.
5216 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5217 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5218 Do not include <signal.h>, as "syssignal.h" does that for us now.
5219 * atimer.c (sigmask_atimers): New function.
5220 (block_atimers, unblock_atimers): New functions,
5221 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5223 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5224 no longer needed here.
5225 * emacs.c (main): Inspect existing signal handler with sigaction,
5226 so that there's no need to block and unblock SIGHUP.
5227 * sysdep.c (struct save_signal): New member 'action', replacing
5228 old member 'handler'.
5229 (save_signal_handlers, restore_signal_handlers):
5230 Use sigaction instead of 'signal' to save and restore.
5231 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5232 New function. All users of 'signal' modified to use set_sighandler
5233 if they're writeonly, and to use sys_signal if they're read+write.
5234 (emacs_sigaction_init, forwarded_signal): New functions.
5235 (sys_signal): Remove. All uses replaced by calls to sigaction
5236 and emacs_sigaction_init, or by direct calls to 'signal'.
5237 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5238 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5239 all uses replaced by pthread_sigmask etc. calls.
5240 * syssignal.h: Include <signal.h>.
5241 (emacs_sigaction_init, forwarded_signal): New decls.
5242 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5243 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5244 (sigmask, sys_sigmask): Remove; no longer needed.
5245 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5246 (sigblock, sigunblock, sigfree):
5247 (sigsetmask) [!defined sigsetmask]:
5248 Remove. All uses replaced by pthread_sigmask.
5249 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5250 no longer need to be replaced, and its typical old uses
5251 are now done via emacs_sigaction_init and sigaction.
5252 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5253 (sys_sigdel): Remove; unused.
5254 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5256 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5258 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5259 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5261 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5263 Explicitly mark buffer_defaults and buffer_local_symbols.
5264 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5265 mark_local_symbols here.
5266 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5267 since special buffers aren't marked here any more.
5268 (allocate_buffer): Chain new buffer with all_buffers here...
5269 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5271 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5272 (syms_of_buffer): Remove staticpro of the above.
5273 (init_buffer_once): Set names for buffer_defaults and
5274 buffer_local_symbols.
5276 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5278 Use bool for booleans in font-related modules.
5279 * font.c (font_intern_prop, font_style_to_value)
5280 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5281 (generate_otf_features, font_check_otf_features, font_check_otf)
5282 (font_match_p, font_list_entities, font_at):
5283 * fontset.c (fontset_id_valid_p, reorder_font_vector
5284 (fontset_find_font, Fset_fontset_font)
5285 (face_suitable_for_char_p) [0]:
5286 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5287 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5288 (m17n_flt_initialized, ftfont_shape_by_flt):
5289 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5290 * nsfont.m (nsfont_draw):
5291 * w32font.c (w32font_draw):
5292 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5293 Use bool for booleans.
5294 * font.h: Adjust to above API changes.
5295 (struct font, struct font_driver, struct font_driver_list):
5296 Use bool for booleans.
5297 (struct font): Remove useless member encoding_type.
5299 * fontset.c, xftfont.c: Omit unnecessary static decls.
5301 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5303 * alloc.c (mark_object): Revert window marking code
5304 since it's unsafe for the Fset_window_configuration.
5306 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5308 Fix race conditions with signal handlers and errno (Bug#12327).
5309 Be more systematic about preserving errno whenever a signal
5310 handler returns, even if it's not in the main thread. Do this by
5311 renaming signal handlers to distinguish between signal delivery
5312 and signal handling. All uses changed.
5313 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5314 * data.c (deliver_arith_signal): Rename from arith_error.
5315 * dispnew.c (deliver_window_change_signal): Rename from
5316 window_change_signal.
5317 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5318 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5319 * keyboard.c (deliver_input_available_signal): Rename from
5320 input_available_signal.
5321 (deliver_user_signal): Rename from handle_user_signal.
5322 (deliver_interrupt_signal): Rename from interrupt_signal.
5323 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5324 (deliver_child_signal): Rename from sigchld_handler.
5325 * atimer.c (handle_alarm_signal):
5326 * data.c (handle_arith_signal):
5327 * dispnew.c (handle_window_change_signal):
5328 * emacs.c (handle_fatal_signal, handle_danger_signal):
5329 * keyboard.c (handle_input_available_signal):
5330 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5331 * process.c (handle_pipe_signal, handle_child_signal):
5332 New functions, with the actual signal-handling code taken from the
5333 original respective signal handlers, sans the sporadic attempts to
5334 preserve errno, since that's now done by handle_on_main_thread.
5335 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5336 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5337 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5339 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5340 Move initialization of main_thread to sysdep.c's init_signals.
5341 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5342 our usage, and simplifies the mainline code.
5343 (record_child_status_change): New static function, as a helper
5344 for handle_child_signal, and with most of the old child handler's
5346 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5347 (handle_child_signal): Use the above.
5348 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5349 Moved here from emacs.c.
5350 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5351 code moved here from emacs.c's main function.
5352 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5353 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5354 This lets callers save and restore errno properly.
5356 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5358 Remove redundant or unused things here and there.
5359 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5360 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5361 * editfns.c (Fcompare_buffer_substrings): Likewise.
5362 * frame.h (struct terminal, struct font_driver_list):
5363 Remove redundant declarations.
5364 * window.h (Qleft, Qright): Likewise.
5366 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5368 Do not mark objects from deleted buffers, windows and frames.
5369 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5370 (mark_object): Likewise for windows and frames.
5372 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5374 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5375 buffer_defaults and buffer_local_symbols as valid objects.
5376 Return special value to denote them.
5378 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5380 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5381 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5382 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5383 (file_name_absolute_p, Fsubstitute_in_file_name):
5384 (check_executable, check_writable, Ffile_accessible_directory_p)
5385 (Fset_file_selinux_context, Fdefault_file_modes)
5386 (Finsert_file_contents, choose_write_coding_system)
5387 (Fwrite_region, build_annotations, a_write, e_write)
5389 * filelock.c (boot_time_initialized, get_boot_time)
5390 (get_boot_time_1, lock_file_1, within_one_second):
5391 * floatfns.c (in_float):
5392 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5393 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5394 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5395 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5396 * window.c (compare_window_configurations):
5397 Use bool for booleans.
5398 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5399 (Fdefault_file_modes): Now mode_t, not int, for modes.
5400 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5401 (internal_delete_file): Now returns void, not a (boolean) int,
5402 since nobody was looking at the return value.
5403 * lisp.h, window.h: Adjust to above API changes.
5405 * xdisp.c (set_message): Simplify and reindent last change.
5407 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5409 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5411 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5413 * eval.c (call_debugger): Make the function non-static so that we
5414 can call it from set_message.
5416 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5417 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5419 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5421 Give more-useful info on a fatal error (Bug#12328).
5422 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5423 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5424 of doing the work ourselves.
5425 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5426 do most of the work.
5427 (fatal_error_backtrace): New function, taken from the guts
5428 of the old fatal_error_signal, but with a new option to output
5430 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5431 info about the signal than just its number.
5432 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5433 * sysdep.c: Include <execinfo.h>
5434 (emacs_backtrace): New function, taken partly from the previous
5435 code of the 'die' function.
5436 (emacs_abort): Call fatal_error_backtrace rather than abort.
5438 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5440 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5441 eager (load-time) macro-expansion.
5442 * lisp.mk (lisp): Add macroexp.
5444 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5446 Simplify redefinition of 'abort' (Bug#12316).
5447 Do not try to redefine the 'abort' function. Instead, redo
5448 the code so that it calls 'emacs_abort' rather than 'abort'.
5449 This removes the need for the NO_ABORT configure-time macro
5450 and makes it easier to change the abort code to do a backtrace.
5451 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5452 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5453 Remove; sysdep.c's emacs_abort now takes its place.
5454 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5455 'abort' changed to use 'emacs_abort'.
5456 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5457 (abort) [!defined abort]: Rename to ...
5458 (emacs_abort): ... new name.
5459 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5460 the place of the old 'abort' in emacs.c.
5461 * w32.c, w32fns.c (abort): Do not #undef.
5462 * w32.c (emacs_abort): Rename from w32_abort.
5464 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5466 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5467 offsets[j].dv, since the y axis of the screen coordinates points
5468 down, while the y axis of the font definition coordinates points
5469 up. This fixes display of Arabic diacritics such as KASRA and
5470 KASRATAN. (Bug#11860)
5472 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5474 Be more systematic about _setjmp vs setjmp.
5475 * alloc.c (test_setjmp, mark_stack):
5476 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5477 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5478 (png_load, my_error_exit, jpeg_load):
5479 * process.c (send_process_trap, send_process):
5480 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5481 The underscored versions are up to 30x faster on some hosts.
5482 Formerly, the code used setjmp+longjmp sometimes and
5483 _setjmp+_longjmp at other times, with no particular reason to
5484 prefer setjmp+longjmp.

5521 * msdos.c (fatal_error_in_progress): ... from here.
5522 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

5525 REDISPLAYING_P when unwinding, instead of saving its previous,
5526 always-false value and then restoring it.
5528 Clean up some extern decls.
5529 Mostly, this hoists extern decls out of .c files and into .h files.
5530 That way, we're more likely to catch errors if the interfaces change.
5531 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5532 declare xg_mark_data.

5557 * xfaces.c: Remove unnecessary static decls.
5558 * xterm.c (updating_frame): Remove decl of nonexistent object.
5560 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5561 when building globals.h, as the objects that are not built on
5562 this host are not needed to compile C files on this host.

5616 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5617 more than one grapheme cluster passed to the shaper: compute the
5618 offset adjustment values separately for each cluster. (Bug#11860)
5620 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5621 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5622 about implicit conversions from integer to pointer.
5624 2012-09-01 Daniel Colascione <dancol@dancol.org>
5626 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5627 system used too early.

5680 window system declarations.
5682 * frame.h: Move common functions here: set_frame_menubar,
5683 x_set_window_size, x_sync, x_get_focus_frame,
5684 x_set_mouse_position, x_set_mouse_pixel_position,
5685 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5746 * lread.c (init_lread): For out-of-tree builds, only add the
5747 source directory's site-lisp dir to the load-path if it exists,
5748 consistent with in-tree builds. (Bug#12302)

5771 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5772 Add window_closed and button_values. Add void as return value for
5773 add(Button|String|Split). addButton takes int instead of Lisp_Object.

5924 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5926 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5928 Fix spare memory change (Bug#12286).
5929 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5930 (valid_lisp_object_p): Likewise.
5932 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5934 * window.c (Fset_window_configuration): Record any window's old
5935 buffer if it's replaced (see Bug#8789). If the new current
5936 buffer doesn't appear in the selected window, go to its old
5939 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5941 Special MEM_TYPE_SPARE to denote reserved memory.
5942 * alloc.c (enum mem_type): New memory type.
5943 (refill_memory_reserve): Use new type for spare memory.
5944 This prevents live_cons_p and live_string_p from incorrect
5945 detection of uninitialized objects from spare memory as live.
5947 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5950 * Makefile.in (.PHONY): versioclean -> versionclean.
5952 Remove unused external symbols.
5953 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5954 * window.c (Qwindow_valid_p, decode_valid_window):
5955 Now static, not extern.
5956 * data.c (Qinterval): Remove; unused.
5957 (syms_of_data): Do not define 'interval'.
5958 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5959 * window.h (decode_valid_window):
5962 * character.c, charset.c, chartab.c: Use bool for booleans.
5963 * character.c (lisp_string_width, string_count_byte8)
5964 (string_escape_byte8):
5965 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5966 (load_charset_map_from_file, map_charset_chars)
5967 (Fdefine_charset_internal, define_charset_internal)
5968 (Fdeclare_equiv_charset, find_charsets_in_text)
5969 (Ffind_charset_region, char_charset, Fiso_charset):
5970 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5971 (sub_char_table_set, sub_char_table_set_range)
5972 (char_table_set_range, optimize_sub_char_table)
5973 (map_sub_char_table):
5974 Use bool for boolean.
5975 * character.c (str_to_unibyte): Omit last boolean argument; it was
5976 always 0. All callers changed.
5977 * character.h, charset.h: Adjust to match previous changes.
5978 * character.h (char_printable_p): Remove decl of nonexistent function.
5979 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5980 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5981 are all boolean, so make them single-bit bitfields.
5983 * lisp.h (ASET): Remove attempt to detect side effects.
5984 It was meant to be temporary and it often doesn't work,
5985 because when IDX has side effects the behavior of IDX==IDX
5986 is undefined. See Stefan Monnier in
5987 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5989 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5991 * lisp.h (functionp): New function (extracted from Ffunctionp).
5992 (FUNCTIONP): Use it.
5993 * eval.c (Ffunctionp): Use it.
5995 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5997 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5998 as that's faster and simpler than static storage. Don't bother
5999 with the g_main_context_query overhead if g_main_context_pending
6000 says no events are pending.
6001 (gfds, gfds_size): Remove these static vars.
6002 (xgselect_initialize): Remove; no longer needed.
6003 All uses and decls removed.
6005 * emacs.c (fatal_error_signal_hook): Remove.
6006 All uses removed. This leftover from old code was always 0.
6008 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6009 * casefiddle.c (casify_object, casify_region):
6010 * casetab.c (set_case_table):
6011 * category.c, category.h (word_boundary_p):
6012 * category.h (CHAR_HAS_CATEGORY):
6013 Use bool for booleans, instead of int.
6015 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6017 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6019 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6021 On assertion failure, print backtrace if available.
6022 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6023 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6024 * Makefile.in (LIB_EXECINFO): New macro.
6027 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6028 * bytecode.c (exec_byte_code):
6029 * callint.c (check_mark, Fcall_interactively):
6030 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6031 (getenv_internal, sync_process_alive, call_process_exited):
6032 * lisp.h (USE_SAFE_ALLOCA):
6033 Use bool for booleans, instead of int.
6034 * lisp.h, process.h: Adjust prototypes to match above changes.
6035 * callint.c (Fcall_interactively): Don't assume the mark's
6036 offset fits in 'int'.
6038 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6040 * buffer.c, buffer.h: Use bool for boolean.
6041 * buffer.c (reset_buffer_local_variables)
6042 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6043 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6044 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6045 (overlay_touches_p, overlay_strings, Foverlay_put)
6046 (report_overlay_modification, call_overlay_mod_hooks):
6047 (mmap_enlarge, mmap_set_vars):
6048 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6049 Use bool for booleans, instead of int.
6050 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6051 since the 1-or-0 return value is always ignored anyway.
6052 (mmap_initialized_p):
6053 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6054 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6056 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6058 * bidi.c: Use bool for boolean.
6059 This is a bit more readable, and makes the text segment of bidi.o
6060 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6061 Presumably it's faster too.
6062 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6064 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6065 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6066 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6067 (bidi_explicit_dir_char, bidi_level_of_next_char)
6068 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6069 Use bool for booleans, instead of int.
6070 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6071 (bidi_unshelve_cache): Adjust decls to match code.
6073 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6075 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6078 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6080 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6081 * atimer.h: Include <stdbool.h>.
6083 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6085 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6086 compile time tests instead of run time tests on systems that do
6088 (FRAME_MAC_P): Remove leftover from deleted code.
6089 * frame.c (syms_of_frame): Remove leftover from deleted code.
6091 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6093 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6095 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6097 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6098 Otherwise, the compiler complains about (A?B:C) where B is void
6099 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6100 (fontset_add): Return void, for FONTSET_ADD.
6102 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6104 * alloc.c: Use bool for booleans.
6105 (gc_in_progress, abort_on_gc)
6106 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6107 (dont_register_blocks) [GC_MALLOC_CHECK]:
6108 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6109 (check_string_bytes, make_specified_string, memory_full)
6110 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6111 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6112 (mark_stack, valid_pointer_p, make_pure_string)
6113 (Fgarbage_collect, survives_gc_p, gc_sweep):
6114 Use bool for booleans, instead of int.
6115 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6116 Remove unused local.
6117 * alloc.c (PURE_POINTER_P):
6118 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6119 * editfns.c (Fformat):
6120 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6122 * fns.c (sweep_weak_table):
6123 * lisp.h (suppress_checking, push_message, survives_gc_p)
6124 (make_pure_string, gc_in_progress, abort_on_gc):
6125 * lread.c (readchar, read1):
6126 * print.c (Fprin1_to_string):
6127 * xdisp.c (push_message):
6128 Use bool for booleans affected directly or indirectly by
6131 Make recently-introduced setters macros.
6132 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6133 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6134 (set_fontset_default, set_fontset_fallback): Rename from their
6135 upper-case counterparts, and make them functions rather than macros.
6136 This is more consistent with the other recently-introduced setters.
6137 These don't need to be inline, since they're local.
6139 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6141 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6142 the loop (Bug#12247).
6144 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6146 * lisp.h (vcopy): Use memcpy rather than our own loop.
6147 This fixes a performance regression introduced by the recent
6148 addition of vcopy. This means 'vcopy' will need to be modified
6149 for a copying collector, but that's OK. Also, tighten the
6150 checking in the assertion.
6152 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6154 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6155 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6156 non-base glyph for the width of the base character, according to
6157 what x_draw_composite_glyph_string_foreground expects.
6158 Generate WADJUST value according to composition_gstring_width's
6159 expectations, to produce correct width of the composed character.
6160 Reverse the sign of the DU offset produced by ScriptPlace.
6162 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6164 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6166 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6168 Avoid direct writes to contents member of struct Lisp_Vector.
6169 * lisp.h (vcopy): New function to copy data into vector.
6170 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6171 * fns.c (Ffillarray): Use ASET.
6172 * keyboard.c (timer_check_2): Use AREF and ASET.
6173 (append_tool_bar_item, Frecent_keys): Use vcopy.
6174 * lread.c (read_vector): Use ASET.
6175 * msdos.c (Frecent_doskeys): Use vcopy.
6176 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6177 (Finternal_merge_in_global_face): Use ASET and vcopy.
6178 * xfont.c (xfont_list_pattern): Likewise.
6180 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6182 * window.c (Fwindow_point): For the selected window always return
6183 the position of its buffer's point.
6184 (Fset_window_point): For the selected window always go in its
6185 buffer to the specified position.
6187 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6189 Setter macros for fontsets.
6190 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6191 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6192 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6195 2012-08-20 Glenn Morris <rgm@gnu.org>
6197 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6198 Don't assume that `ln -f' works.
6200 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6202 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6203 and later about non-assignments with no effect. See discussion at
6204 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6207 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6209 Inline setter functions for Lisp_Objects slots of struct specbinding.
6210 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6213 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6215 * window.c (select_window): Always make selected window's buffer
6218 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6220 Use AREF and ASET for docstrings of category tables.
6221 * category.h (CATEGORY_DOCSTRING): Use AREF.
6222 (SET_CATEGORY_DOCSTRING): Use ASET.
6223 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6225 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6227 Inline setter functions for hash table members.
6228 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6229 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6230 (set_hash_key_and_value, set_hash_index, set_hash_next)
6231 (set_hash_hash): New functions.
6232 * charset.c, fns.c: Adjust users.
6234 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6236 Inline getter and setter functions for per-buffer values.
6237 * buffer.h (per_buffer_default, set_per_buffer_default)
6238 (per_buffer_value, set_per_buffer_value): New functions.
6239 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6240 * buffer.c, data.c: Adjust users.
6242 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6244 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6246 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6248 Rely on <config.h> + <unistd.h> to declare 'environ',
6249 as gnulib does this if the system doesn't.
6250 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6251 Remove declaration. MS-Windows declares it on stdlib.h which is
6252 included by conf_post.h.
6253 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6254 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6255 * vm-limit.c: Include <unistd.h>, for 'environ'.
6257 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6258 (start_of_data): Remove decl; mem-limits.h provides it.
6260 * xdisp.c (handle_invisible_prop): Make it a bit faster
6261 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6263 2012-08-19 Chong Yidong <cyd@gnu.org>
6265 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6268 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6270 * .gdbinit: Use call instead of set when calling a function in the
6273 * data.c (set_internal): Don't use set_blv_found.
6274 (Fkill_local_variable): Likewise.
6276 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6278 * nsfont.m (ns_ascii_average_width): Ensure the string
6279 ascii_printable is initialized with a null-terminated character
6280 array. Otherwise, it can contain undesired extra characters.
6282 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6284 port new setting code to Sun C 5.8 2005/10/13
6285 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6286 Return void, not Lisp_Object. Otherwise, the compiler
6287 complains about (A?B:C) where B is void and C is Lisp_Object
6288 when compiling CHAR_TABLE_SET, due to the recent change to
6289 the API of sub_char_table_set_contents.
6291 2012-08-18 Chong Yidong <cyd@gnu.org>
6293 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6294 for the string case (Bug#3874).
6296 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6298 * buffer.h (BSET): Remove (Bug#12215).
6299 Replace all uses with calls to new setter functions.

6327 * category.c (bset_category_table):
6328 * syntax.c (bset_syntax_table):
6329 New setter functions.
6331 * process.h (PSET): Remove (Bug#12215).
6332 Replace all uses with calls to new setter functions.

6334 (PROCESS_INLINE): New macro.
6335 (pset_childp): New setter function.
6336 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
6337 * process.c (PROCESS_INLINE):
6338 Define to EXTERN_INLINE, so that the corresponding functions
6339 are compiled into code.
6340 (pset_buffer, pset_command, pset_decode_coding_system)

6343 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
6344 (pset_type, pset_write_queue): New setter functions.
6346 * window.h (WSET): Remove (Bug#12215).
6347 Replace all uses with calls to new setter functions.
6348 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
6349 (WINDOW_INLINE): New macro.

6353 (wset_window_end_pos, wset_window_end_valid)
6354 (wset_window_end_vpos): New setter functions.

7126 value of EMACSLOADPATH, as it is no longer needed.
7127 (check_windows_init_file): Now external, not static.

7133 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7178 * alloc.c (record_xmalloc): New function.
7179 * lisp.h (record_xmalloc): New decl.
7180 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7181 more like a function. This is because the pointer cast is not
7182 needed. All uses changed.
7183 * print.c (print_string, print_error_message): Avoid length recalc.
7185 Improve fix for macroexp crash with debugging (Bug#12118).
7186 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7187 ARRAY_MARK_FLAG when checking subscripts, because ASET is

7220 with addition of handling of symlinks and support for 'lstat'.
7221 If possible, get file's attributes and security information by
7222 handle, not by name. Produce S_IFLNK bit for symlinks, when
7223 called from 'lstat'.
7224 (stat, lstat): New functions, call 'stat_worker'.
7225 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7226 symlinks when the underlying filesystem supports them.
7228 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7230 Fix macroexp crash on Windows with debugging (Bug#12118).
7231 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7232 checking subscripts; problem introduced with the recent
7233 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.

7705 * alloc.c (listn): Fix the order the arguments are consed onto the
7708 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7709 enumeration constants, as PURE and HEAP are too general, and clash
7710 with other headers and sources, such as gmalloc.c and the
7711 MS-Windows system headers. All users changed.
7713 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7715 Revert last save_excursion_save and save_excursion_restore changes.
7716 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7726 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7728 Improve GDB symbol export (Bug#12036).
7729 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7730 arms of an 'if', not using conditional expressions; otherwise GDB
7731 complains about the types in the unevaluated arm when the argument
7732 is an integer literal.
7733 (xgetint): Simplify expression.
7734 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7735 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7736 Zaretskii in <http://bugs.gnu.org/12036#13>.
7737 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7738 needed now that we have gdb_make_enums_visible.
7739 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7740 (enum enum_USE_LSB_TAG):
7741 New enum types, packaging up enums that need to be exported to GDB.
7743 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7745 Utility function to make a list from specified amount of objects.

7758 * w32fns.c (Fw32_battery_status, syms_of_w32fns): Likewise.
7759 * xdisp.c (syms_of_xdisp): Likewise.
7760 * xfns.c (syms_of_xfns): Likewise.
7762 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7764 Fast save_excursion_save and save_excursion_restore.
7765 * lisp.h (struct Lisp_Excursion): New data type.
7766 (PVEC_EXCURSION): New pseudovector type.
7767 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7768 to deal with it. Adjust comments.
7769 (init_marker, attach_marker): New prototype.
7770 (unchain_marker): Adjust prototype.
7771 * marker.c (attach_marker): Change to global.

7776 * editfns.c (save_excursion_save, save_excursion_restore):
7777 Reimplement to use struct Lisp_Excursion. Add comments.
7779 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7781 Fix export of symbols to GDB (Bug#12036).
7782 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
7783 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7784 emacs.c, as this is a more-suitable home. Had this been done earlier
7785 the fix for 12036 would have avoided some of the problems noted in
7786 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7787 would have been more obvious.
7788 * emacs.c: Do not include <verify.h>; no longer needed.
7789 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7790 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7791 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7792 Remove; now done in lisp.h.
7793 * lisp.h (PUBLISH_TO_GDB): New macro.
7794 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
7795 (DATA_SEG_BITS): Use it.
7796 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7797 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7798 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7799 not be usable in #if. This simplifies things.
7801 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7803 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7805 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7807 Simplify export of symbols to GDB (Bug#12036).
7808 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7809 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7810 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7811 Adjust to changes in lisp.h and emacs.c, by using
7812 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7813 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7814 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7815 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7816 instead of gdb_valbits.
7817 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7818 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7819 instead of gdb_array_mark_flag.
7820 (xboolvector): Get size from $->size, not $->header.size.
7821 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7822 (xreload, hook-run, hookpost-run): Remove.
7823 * emacs.c: Include <verify.h>.
7824 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7825 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7827 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7828 (gdb_USE_LSB_TAG): New enum constants.
7829 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7830 Also define these as enum constants, so they're visible to GDB.
7831 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7832 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7833 as constants, so they're visible to GDB.
7834 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7835 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7836 Now enum constants, not macros, so they're visible to GDB.
7837 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7838 more convenient now. All uses changed.
7839 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7840 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7842 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
7844 Explicitly free restriction data that are not needed anymore.

7847 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7849 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7850 add argument, tune behavior, and adjust all callers.
7852 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7854 Use typedef for EMACS_INT, EMACS_UINT.
7855 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7856 than macros. This simplifies debugging in the usual case, since
7857 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7858 and it allows expressions involving EMACS_INT casts.
7859 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7861 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
7863 * nsterm.m (ns_read_socket): Return early if there is a modal

7869 that FOCUS-FRAME can be omitted.
7871 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7873 Adjust buffer text indirection counters at the end of Fkill_buffer.
7874 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7875 buffer is definitely dead. This should really fix an issue reported
7876 by Christoph Scholtes again. (Bug#12007).
7877 (init_buffer_once): Initialize indirection counters of
7878 buffer_defaults and buffer_local_symbols (for sanity and safety).
7880 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7882 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7883 and continuation glyphs on tooltip frames, leave them at zero.
7884 Avoids continued lines in tooltips. (Bug#11832)
7886 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7888 Simplify copy_overlay.
7889 * buffer.c (copy_overlay): Simplify. Use build_marker.

7895 or invalid. (Bug#12025)
7897 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
7898 it signals an error when a tooltip frame is being created.
7900 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7902 Cleanup miscellaneous objects allocation and initialization.
7903 * alloc.c (allocate_misc): Change to static. Add argument to
7904 specify the subtype. Adjust comment and users.

7909 (build_overlay): Add prototype.
7911 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7913 Swap buffer text indirection counters in Fbuffer_swap_text.
7914 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7915 This avoids crash reported by Christoph Scholtes at
7916 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7918 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7920 * nsmenu.m (Popdown_data): New struct.
7921 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7923 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7924 (initWithContentRect): Make imgView and contentView non-static
7925 and autorelease them. Also autorelease img and matrix (Bug#12005).
7926 (dealloc): Remove (Bug#12005).
7928 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7930 Adjust consing_since_gc when objects are explicitly freed.
7931 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
7932 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
7933 (free_cons, free_misc): Subtract object size from consing_since_gc.
7935 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7937 Simplify and cleanup markers positioning code.
7938 * marker.c (attach_marker): More useful eassert.
7939 (live_buffer, set_marker_internal): New function.
7940 (Fset_marker, set_marker_restricted): Use set_marker_internal.
7941 (set_marker_both, set_marker_restricted_both): Use live_buffer.
7943 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7945 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7946 as it's limited by the amount of memory, not by INT_MAX.
7948 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7950 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7951 in special-event-map. See the discussion at
7952 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
7955 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
7956 info.dwItemData. Fixes crashes on 64-bit Windows.

7973 * buffer.h (struct buffer): New member.
7974 * buffer.c (Fget_buffer_create): Set indirection counter to 0.
7975 (Fmake_indirect_buffer): Set indirection counter to -1, increment
7976 base buffer indirection counter.
7977 (compact_buffer): If ENABLE_CHECKING, verify indirection counters.

8010 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8011 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8012 Adjust users accordingly.
8013 * font.h (font_open_by_name): Adjust prototype.
8015 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

8024 * bytecode.c (MAYBE_GC): Use maybe_gc.
8025 * eval.c (eval_sub, Ffuncall): Likewise.
8026 * keyboard.c (read_char): Likewise. Adjust call to maybe_gc
8027 to avoid dependency from auto-save feature.
8029 2012-07-19 Paul Eggert <eggert@cs.ucla.edu>
8031 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8032 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8033 'for_each_per_buffer_object_at'.
8034 All uses changed. It's better to use upper-case for macros that
8035 cannot be implemented as functions, to give the reader a clue
8036 that they're special.
8038 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8040 * alloc.c (Fgarbage_collect): Tweak docstring.

8080 Fix bug that created negative-length intervals.
8081 * intervals.c (merge_interval_right, merge_interval_left):
8082 Do not zero out this interval if it is absorbed by its children,
8083 as this interval's total length doesn't change in that case. See
8084 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8086 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8088 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8089 when invoking (make-bool-vector N t) and N is a positive
8090 multiple of 8 -- the last 8 bits were mistakenly cleared.
8092 Remove some struct layout assumptions in bool vectors.
8093 * alloc.c (bool_header_size): New constant.
8094 (header_size, word_size): Move earlier, as they're now used earlier.
8095 Use 'word_size' in a few more places, where it's appropriate.
8096 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
8097 padding before the data member of a bool vector.
8098 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
8099 than doing the check by hand with an abort ().
8101 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8103 * eval.c (Fdefvar): Don't check constants since we only set the var if
8104 it's not yet defined anyway (bug#11904).
8106 * lisp.h (last_undo_boundary): Declare new var.
8107 * keyboard.c (command_loop_1): Set it.
8108 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8109 were auto-added by the command loop (bug#11774).
8111 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
8113 * w32font.c (Qsymbol): Remove local definition.

8602 2012-07-11 Glenn Morris <rgm@gnu.org>
8604 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8605 since nothing has defined it on these platforms.
8607 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
8608 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

8614 * s/gnu.h: Remove file, which is now empty.
8616 * s/gnu.h, s/gnu-linux.h:
8617 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
8619 2012-07-11 John Wiegley <johnw@newartisans.com>
8621 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8622 function attribute, so we only use it if it exists in the
8625 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8627 Avoid call to strlen in fast_c_string_match_ignore_case.
8628 * search.c (fast_c_string_match_ignore_case): Change to use
8629 length argument. Adjust users accordingly.
8630 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
8632 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

8673 Remove "#define unix" that is no longer needed (Bug#11905).
8674 * s/aix4-2.h (unix): Remove; no longer needed.
8676 EMACS_TIME simplification (Bug#11875).
8677 This replaces macros (which typically do not work in GDB)
8678 with functions, typedefs and enums, making the code easier to debug.
8679 The functional style also makes code easier to read and maintain.
8680 * systime.h: Include <sys/time.h> on all hosts, not just if
8681 WINDOWSNT, since 'struct timeval' is needed in general.
8682 (EMACS_TIME): Now a typedef, not a macro.
8683 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8685 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8689 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8690 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8691 which are not functions. All uses rewritten to use:
8692 (make_emacs_time): New function.
8693 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8694 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8695 not functions. All uses rewritten to use the following, respectively:
8696 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8697 (add_emacs_time, sub_emacs_time): New functions.
8698 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8699 * fileio.c (Fcopy_file):
8700 * xterm.c (XTflash): Get the current time closer to when it's used.
8701 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8709 * gtkutil.c (get_utf8_string):
8711 * nsmenu.m (ns_update_menubar):
8712 * regex.c (regerror):
8713 Prefer memcpy to strncpy and strncat when either will do.
8714 * fileio.c (Fsubstitute_in_file_name):
8715 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8716 (menu_separator_name_p):
8717 * nsmenu.m (ns_update_menubar):
8718 Prefer memcmp to strncmp when either will do.
8719 * nsterm.m: Include <ftoastr.h>.
8721 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8722 Prefer snprintf to strncpy.
8723 * nsterm.m (ns_term_init):
8724 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8725 * nsterm.m (ns_term_init):
8726 Avoid the need for strncpy, by using build_string or
8727 make_unibyte_string directly. Use dtoastr, not snprintf.
8728 * process.c (Fmake_network_process): Diagnose service names that
8729 are too long, rather than silently truncating them or creating
8730 non-null-terminated names.
8731 (Fnetwork_interface_info): Likewise, for interface names.
8732 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8733 Prefer sprintf to strncat.
8734 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8735 Prefer vsnprintf to vsprintf + strncpy.
8737 2012-07-10 Glenn Morris <rgm@gnu.org>
8739 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8740 Clarify fallback case.
8742 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8744 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8745 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8746 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8747 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8748 where argument type is known to be a Lisp_Cons.
8750 2012-07-10 Tom Tromey <tromey@redhat.com>
8752 * bytecode.c (BYTE_CODE_THREADED): New macro.
8753 (BYTE_CODES): New macro. Replaces all old byte-code defines.

8760 Optimize pure C strings initialization.
8761 * lisp.h (make_pure_string): Fix prototype.
8762 (build_pure_c_string): New function, defined as static inline. This
8763 provides a better opportunity to optimize away calls to strlen when
8764 the function is called with compile-time constant argument.
8765 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8766 argument, adjust users accordingly. Use build_pure_c_string where
8768 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8769 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8770 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8772 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8774 Avoid calls to strlen in miscellaneous functions.
8775 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8776 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8777 * lread.c (openp): Likewise.
8779 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8781 Avoid calls to strlen in path processing functions.
8782 * fileio.c (file_name_as_directory): Add comment. Change to add
8783 srclen argument and return the length of result. Adjust users
8785 (directory_file_name): Fix comment. Change to add srclen argument,
8786 swap 1st and 2nd arguments to obey the common convention.
8787 Adjust users accordingly.
8788 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8790 2012-07-10 Glenn Morris <rgm@gnu.org>
8792 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8795 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8796 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8797 * s/gnu.h (DATA_START): Move definitions to configure.
8799 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8800 We include usg5-4-common.h, which defines them both.
8802 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8803 O_RDONLY already includes it).
8805 Stop ns builds setting the EMACSLOADPATH environment variable.
8806 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8807 Now it does not set EMACSLOADPATH, just returns the load-path string.
8808 * nsterm.h: Update accordingly.
8809 * lread.c [HAVE_NS]: Include nsterm.h.
8810 (init_lread) [HAVE_NS]: Use ns_load_path.
8811 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8813 2012-07-09 Glenn Morris <rgm@gnu.org>
8815 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8816 since the included bsd-common.h does so.
8818 Stop ns builds setting the EMACSPATH environment variable.
8819 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8820 (ns_init_paths): Do not set EMACSPATH.
8821 * nsterm.h (ns_exec_path): Add it.
8822 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8825 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8827 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8829 * process.c (wait_reading_process_output): 'waitchannels' was unset
8830 when read_kbd || !NILP (wait_for_cell); fix this.
8832 Add GCC-style 'const' attribute to functions that can use it.
8833 * character.h (char_resolve_modifier_mask):
8834 * keyboard.h (make_ctrl_char):
8835 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8836 (init_character_once, next_almost_prime, init_fns, init_image)
8837 (flush_pending_output, init_sound):
8838 * mem-limits.h (start_of_data):

8842 Declare the dummy function with ATTRIBUTE_CONST.
8843 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8844 Add decls with ATTRIBUTE_CONST.
8846 Minor improvements to make_formatted_string.
8847 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8848 where int is good enough, as vsprintf returns an int.
8849 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8851 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8853 Use make_formatted_string to avoid double length calculation.
8854 * lisp.h (make_formatted_string): New prototype.
8855 * alloc.c (make_formatted_string): New function.
8856 * buffer.c (Fgenerate_new_buffer_name): Use it.
8857 * dbusbind.c (syms_of_dbusbind): Likewise.

8859 * filelock.c (get_boot_time): Likewise.
8860 * frame.c (make_terminal_frame, set_term_frame_name)
8861 (x_report_frame_params): Likewise.
8862 * image.c (gs_load): Likewise.
8863 * minibuf.c (get_minibuffer): Likewise.

8878 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8880 Move marker debugging code under MARKER_DEBUG.
8881 * marker.c (MARKER_DEBUG): Move marker debugging code under
8882 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8883 for bootstrap with --enable-checking (~3x slowdown reported
8884 by Juanma Barranquero <lekktu@gmail.com>).
8885 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8887 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8889 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8890 See <http://bugs.gnu.org/11825#29>.
8892 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8894 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8895 has no font, use the frame's font. (Bug#11813)
8896 (display_line): Add commentary about displaying truncation glyphs
8898 (produce_special_glyphs): Move here from term.c.
8900 * term.c (produce_special_glyphs): Move to xdisp.c.
8902 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8905 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8907 * xdisp.c (display_line): Avoid warning about implicit declaration
8910 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8912 * lisp.h: Remove empty conditional.
8914 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8916 * lread.c (load_path_check): Now static.
8918 Fix some minor --with-ns problems found by static checking.
8919 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8920 (x_set_font) [!HAVE_X_WINDOWS]:
8921 * image.c (xpm_load_image) [HAVE_NS]:
8922 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8923 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8924 Remove unused local.
8925 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8926 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8927 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8928 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8929 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8930 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8931 Fix pointer signedness problem.
8932 * xfaces.c (FRAME_X_FONT_TABLE):
8933 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8935 2012-07-07 Glenn Morris <rgm@gnu.org>
8937 * lread.c (load_path_check): New function, split from init_lread.
8938 (init_lread): Reorganize. Motivation:
8939 If EMACSLOADPATH is set, check/warn about that rather than the
8940 defaults, which we are not going to use. Hence we can remove
8941 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8942 Don't warn if site-lisp directories are missing.
8943 If not installed, start from a blank load-path, since
8944 PATH_LOADSEARCH refers to the eventual installation directories.
8946 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8948 Support truncation and continuation glyphs on GUI frames, when
8949 fringes are disabled. (Bug#11832)
8950 * xdisp.c (init_iterator): Get dimensions of truncation and
8951 continuation glyphs even if on GUI frames.
8952 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8953 or both, are absent.
8954 (start_display, move_it_in_display_line_to): Handle the case of a
8955 GUI frame without a fringe to display continuation or truncation
8957 (insert_left_trunc_glyphs): Support GUI frames: make sure
8958 truncation glyphs overwrite enough glyphs from the current line to
8959 have sufficient space in pixels.
8960 (display_line): Support truncation and continuation glyphs on GUI
8961 frames. If some spare pixels are left on the line after inserting
8962 the truncation glyphs, fill that space with a stretch glyph of a
8963 suitably computed width.
8965 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8966 produce_glyphs, to support GUI sessions.
8968 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8970 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8972 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8974 Do not require float-time's arg to fit in time_t (Bug#11825).
8975 This works better on hosts where time_t is unsigned, and where
8976 float-time is applied to the (negative) difference between two times.
8977 * editfns.c (decode_time_components): Last arg is now double *,
8978 not int *, and means to store all the result as a double, without
8979 worrying about whether the seconds part fits in time_t.
8980 All callers changed.
8981 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8982 All callers changed.
8983 (Ffloat_time): Do not fail merely because the specified time falls
8984 outside of time_t range.
8986 2012-07-07 Glenn Morris <rgm@gnu.org>
8988 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8992 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8994 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8995 Update dependencies.
8997 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8999 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9001 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9002 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9003 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9004 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9005 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9006 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9008 * xfont.c (compare_font_names): Redo to omit the need for casts.
9010 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9012 * xfns.c (Fx_change_window_property): Doc fix.
9013 * w32fns.c (Fx_change_window_property): Doc fix.
9015 * w32fns.c (Fx_window_property): Accept the same arguments as the
9016 X Windows version. Doc fix.
9017 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9019 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9020 Eli Zaretskii <eliz@gnu.org>
9022 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9023 Windows-specific code from nt/config.nt moved here.
9024 Obsolete settings removed.
9026 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9028 * process.c: Avoid unnecessary calls to gettime.
9029 (wait_reading_process_output): Don't get the time of day
9030 when gobbling data immediately and not waiting, as there's no need
9031 for it in that case. This removes a FIXME.
9033 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9035 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9036 is defined (Bug#11768).

9040 Fix marker debugging code.
9041 * marker.c (byte_char_debug_check): Do not perform the check
9042 if buffer is not multibyte.
9043 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9044 Call byte_char_debug_check with correct arguments.
9046 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9048 Compile marker debugging code only if ENABLE_CHECKING is defined.
9049 * marker.c (byte_char_debug_check, count_markers):
9050 Use only if ENABLE_CHECKING is defined.
9051 (byte_debug_flag): Remove.
9052 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9053 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9055 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9057 Avoid code repetition in marker-related functions.
9058 * marker.c (attach_marker): New function.

9061 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9062 Consistently rename charno to charpos.
9063 (marker_position): Add eassert.
9064 (marker_byte_position): Convert to eassert.
9066 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9076 * lisp.h (build_marker): New prototype.
9077 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9078 * composite.c (autocmp_chars): Likewise.
9079 * editfns.c (buildmark): Remove.
9080 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9081 (save_restriction_save): Use build_marker.
9082 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9083 * window.c (save_window_save): Likewise.
9085 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

9088 to avoid redundant calls to unchain_overlay.
9089 * buffer.c (drop_overlay): New function.
9090 (delete_all_overlays, Fdelete_overlay): Use it.
9091 * minibuf.c (get_minibuffer): Fix comment.
9093 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9095 Port to OpenBSD 5.1 amd64.
9096 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9097 This is needed for OpenBSD, and should be harmless on all BSD systems.
9098 Also, include <sys/sysctl.h>, as it should be available on all
9099 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9100 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9101 use p_pid member, not kp_proc.pid.
9103 2012-07-06 Glenn Morris <rgm@gnu.org>
9105 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9107 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9109 More xmalloc and related cleanup.
9110 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

9118 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9120 Omit needless casts involving void * pointers and allocation.
9121 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9122 as the former is more robust if P's type is changed.
9123 Prefer xzalloc to xmalloc + memset 0.
9124 Simplify malloc-or-realloc to realloc.
9125 Don't worry about xmalloc returning a null pointer.
9126 Prefer xstrdup to xmalloc + strcpy.
9127 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9129 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9130 alloca of a constant.
9132 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9134 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9135 hscroll is larger than the line width. Fixes long and futile
9136 looping inside extend_face_to_end_of_line (on a TTY) producing
9137 glyphs that are not needed and thrown away.
9139 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9141 * marker.c (set_marker_restricted_both): Simplify by using
9144 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9146 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9148 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

9151 not defined (Bug#11768).
9152 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9153 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9154 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9155 followed by gtk_box_set_homogeneous (Bug#11768).
9156 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9157 (update_theme_scrollbar_width, xg_create_scroll_bar):
9158 Use gtk_scrollbar_new (Bug#11768).
9159 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9160 (is_box_type): New function (Bug#11768).
9161 (xg_tool_item_stale_p): Call is_box_type.
9162 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9163 with default display (Bug#11768).

9167 * xdisp.c (window_hscroll_limited): New function.
9168 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9169 coordinates when window's hscroll is set to insanely large
9172 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9174 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9233 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9235 * fileio.c (time_error_value): Check the right error number.
9236 Problem reported by Troels Nielsen in
9237 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9239 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9241 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9242 This should be fixed in a better way; see Eli Zaretskii in
9243 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9244 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9246 * fileio.c (time_error_value): Rename from special_mtime.
9247 The old name's problems were noted by Eli Zaretskii in
9248 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9250 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9251 This variable's comment says Emacs needs at least one GDB-visible
9252 symbol of type enum pvec_type, to work around GDB problems.
9253 The symbol's value doesn't matter.
9255 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9256 that causes compilation to fail on pre-C99 compilers.
9258 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9260 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9261 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9263 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9265 * buffer.c (init_buffer_once): Fix initialization of
9266 headers for buffer_defaults and buffer_local_symbols.
9267 Reported by Juanma Barranquero <lekktu@gmail.com>.
9269 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9271 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9272 * lisp.h (enum pvec_type): Use fewer bits.
9273 (PSEUDOVECTOR_SIZE_BITS): New constant.
9274 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9275 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9276 change in pvec_type.
9277 (PSEUDOVECTOR_TYPEP): New macro.
9278 (TYPED_PSEUDOVECTORP): Use it.
9279 * fns.c (internal_equal): Adapt code to extract pvectype.

9283 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9284 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9285 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9286 abusing vector->header.next.nbytes.
9287 (live_vector_p): Use PVEC_TYPE.
9288 (mark_object): Adapt code to extract pvectype. Use switch.
9290 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9292 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9293 Tighten new eassert a bit.
9295 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9297 Fix compilation with --enable-gcc-warnings and -O1
9299 * doprnt.c (doprnt): Change type of tem to int, initialize
9300 to avoid compiler warning. Add eassert.
9301 * search.c (simple_search): Initialize match_byte to avoid
9302 compiler warning. Add eassert.
9304 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9306 Avoid weird behavior with large horizontal scrolls.
9307 Without this change, for example, large hscroll values would
9308 mess up Emacs's display on Fedora 15 x86, presumably due to
9309 overflows in int calculations in the display code.
9310 Also, if buffers had long lines, Emacs would freeze.
9311 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9312 (set_window_hscroll): New function, containing the old guts of
9313 Fset_window_hscroll. Return the clipped value.
9314 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9315 This avoids the need to check against PTRDIFF_MAX.
9317 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9319 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9321 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9323 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9325 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9326 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9327 since GCC 4.4.6 issues a bogus warning for them.
9329 Fix bugs in file timestamp newness comparisons.
9330 * fileio.c (Ffile_newer_than_file_p):
9331 * lread.c (Fload): Use full timestamp resolution of files,
9332 not just the 1-second resolution, so that files that are only
9333 slightly newer still count as newer.
9334 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9335 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9337 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9339 * fileio.c: Improve handling of file time marker. (Bug#11852)
9340 (special_mtime): New function.
9341 (Finsert_file_contents, Fverify_visited_file_modtime):
9342 Use it to set special mtime values consistently.
9344 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9346 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9347 marker for non-existing file. (Bug#11852)
9349 2012-07-03 Glenn Morris <rgm@gnu.org>
9351 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9352 and did not make it into globals.h).
9354 2012-07-03 Tom Tromey <tromey@redhat.com>
9356 * window.c (Fset_window_margins, Fset_window_fringes)

9392 2012-07-03 Glenn Morris <rgm@gnu.org>
9394 * lisp.h (Frandom): Make it visible to C.
9395 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9396 buffer for invisible buffers. (Bug#1229)

9400 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9401 values which aren't power of 2.
9402 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9403 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9406 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9408 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

9412 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9414 * alloc.c (allocate_vector_block): Remove redundant
9415 calls to mallopt if DOUG_LEA_MALLOC is defined.
9416 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9417 avoid calls to mallopt if zero_vector is returned.
9419 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9421 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9422 is enabled, avoid dereferencing NULL current_sblock if
9425 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9427 Cleanup basic buffer management.
9428 * buffer.h (struct buffer): Change layout to use generic vector
9429 marking code. Fix some comments. Change type of 'clip_changed'
9430 to bitfield. Remove unused #ifndef old.
9431 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9432 (GET_OVERLAYS_AT): Fix indentation.

9437 * alloc.c (allocate_buffer): Adjust to match new layout of
9438 struct buffer. Fix comment.
9439 (mark_overlay): New function.
9440 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9441 Lisp area of struct buffer.
9442 (mark_object): Use it. Adjust marking of misc objects
9443 and related comments.
9445 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9447 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9448 wrapper that is not needed because the wrapped code is a no-op (zero
9449 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9450 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9452 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9454 * alloc.c (mark_buffer): Simplify. Remove prototype.
9455 (mark_object): Add comment. Reorganize marking of vector-like
9456 objects. Use CHECK_LIVE for all vector-like objects except buffers
9457 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9458 Avoid redundant calls to mark_vectorlike for bool vectors.
9460 2012-06-30 Glenn Morris <rgm@gnu.org>
9462 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9464 * epaths.in (PATH_SITELOADSEARCH): New.
9465 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9466 This is rather than relying on --enable-locallisppath elements
9467 having "site-lisp" in their names. (Bug#10208#25, 11658)
9469 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9471 * w32proc.c (sys_select): Accept and ignore one more argument.
9473 * w32.c (emacs_gnutls_pull): Call select with one more argument.

9480 * process.c (sys_select):
9481 * msdos.c (sys_select): Accept one more argument and ignore it.
9483 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9484 adapt data types and code to that.
9487 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9488 which clashes with the gnulib function of the same name.
9490 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9492 * font.c (font_style_to_value, font_style_symbolic)
9493 (font_prop_validate_style): Add type checks for values in
9496 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9498 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9501 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9503 * xdisp.c (try_window_id): Undo last change.
9505 * w32.c (getwd): Adjust commentary about startup_dir.
9506 (init_environment): Always call sys_access, even in non-MSVC
9507 builds. Don't chdir to the directory of the Emacs executable.
9508 This undoes code from 1997 which was justified by the need to
9509 "avoid conflicts when removing and renaming directories". But its
9510 downside was that every relative file name was being interpreted
9511 relative to the directory of the Emacs executable, which can never
9512 be TRT. In particular, it broke sys_access when called with
9513 relative file names.
9514 (sys_access): Map GetLastError to errno.
9516 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

9698 * alloc.c: Remove build_string.

9700 a better opportunity to optimize away calls to strlen when the
9701 function is called with compile-time constant argument.

9706 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9708 Use sprintf return value instead of invoking strlen on result.
9709 In the old days this wasn't portable, since some sprintf
9710 implementations returned char *. But they died out years ago and
9711 Emacs already assumes sprintf returns int.
9712 Similarly for float_to_string.
9713 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9721 Use sprintf or float_to_string result to avoid need to call strlen.
9722 * data.c (Fnumber_to_string):
9723 Use make_unibyte_string, since the string must be ASCII.
9724 * lisp.h, print.c (float_to_string): Now returns int length.
9725 * term.c (produce_glyphless_glyph):
9726 Use sprintf result rather than recomputing it.
9728 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9729 * Makefile.in (ALL_CFLAGS):
9730 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

9759 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9761 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9764 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9766 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9767 instead of truncating it to 63 (admittedly a generous limit).

9827 * keyboard.c (kbd_buffer_get_event):
9828 * process.c (Faccept_process_output):
9829 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9830 This improves on the previous patch, which introduced a bug

9851 Privately reported by Herbert J. Skuhra.
9852 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

9897 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9899 Support higher-resolution time stamps (Bug#9000).
9900 The time stamps are only nanosecond-resolution at the C level,
9901 since that's the best that any real-world system supports now.
9902 But they are picosecond-resolution at the Lisp level, as that's
9903 easy, and leaves room for future OS improvements.
9905 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9908 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9909 Don't get current time unless it's needed.
9911 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9912 now provides it if it's absent.
9913 (start_atimer): Port to higher-res time stamps.
9914 Check for time stamp overflow. Don't get current time more
9915 often than is needed.
9917 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9918 Include systime.h, not time.h.
9919 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9921 * dired.c: Include stat-time.h.
9922 (Ffile-attributes): File times now have higher resolution.
9924 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9925 (struct image): Timestamp now has higher resolution.
9927 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9928 has at least microseconds now. All uses removed.
9929 (update_frame, update_single_window, update_window, update_frame_1)
9930 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9931 (duration_to_sec_usec): Remove; no longer needed.
9933 * editfns.c (time_overflow): Now extern.
9934 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9935 (float-time, Fformat_time_string, Fcurrent_time_string)

9938 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9939 (decode_time_components, lisp_seconds_argument): New functions.
9940 (make_time): Now static.
9941 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9942 Report an error if the time is invalid, rather than having the caller
9945 * fileio.c: Include <stat-time.h>
9946 (Fcopy_file): Copy higher-resolution time stamps.
9947 Prefer to set the time stamp via a file descriptor if that works.
9948 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9949 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9950 (Fvisited_file_modtime, Fset_visited_file_modtime):
9951 Support higher-resolution time stamps.
9953 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9955 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9957 * image.c (prepare_image_for_display, clear_image_cache)
9958 (lookup_image): Port to higer-resolution time stamps.
9960 * keyboard.c (start_polling, bind_polling_period):
9961 Check for time stamp overflow.
9962 (read_char, kbd_buffer_get_event, timer_start_idle)
9963 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9964 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9965 Port to higher-resolution time stamps. Do not assume time_t is signed.
9966 (decode_timer): New function. Timers are now vectors of length 9,
9967 not 8, to accommodate the picosecond component.
9968 (timer_check_2): Use it.
9970 * nsterm.m (select_timeout, timeval_subtract): Remove.
9971 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9972 as they're a bit more accurate and handle overflow better.
9973 (ns_select): Change prototype to be compatible with pselect.
9974 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9975 * nsterm.h (ns_select): Adjust prototype.
9977 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9978 us-resolution time stamps.
9979 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9981 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9983 * lisp.h (time_overflow): New decl.
9984 (wait_reading_process_output): First arg is now intmax_t, not int,
9985 to accommodate larger waits.
9987 * process.h (struct Lisp_Process.read_output_delay):
9988 Now counts nanoseconds, not microseconds.
9989 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9991 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9992 (wait_reading_process_output):
9993 Port to ns-resolution time stamps.
9994 (Faccept_process_output, wait_reading_process_output):
9995 Check for time stamp overflow. Do not assume time_t is signed.
9996 (select_wrapper): Remove; we now use pselect.
9997 (Fprocess_attributes): Now generates ns-resolution time stamps.
9999 * sysdep.c: Include utimens.h. Don't include utime.h
10000 or worry about struct utimbuf; gnulib does that for us now.
10001 (gettimeofday): Remove; gnulib provides a substitute.
10002 (make_timeval): New function.
10003 (set_file_times): Now sets ns-resolution time stamps.
10004 New arg FD; all uses changed.
10005 (time_from_jiffies, ltime_from_jiffies, get_up_time)

10007 Now returns ns-resolution time stamp. All uses changed.
10008 Check for time stamp overflow.

10011 provides a substitute now.
10013 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10014 since it guarantees struct timespec.
10015 (EMACS_TIME): Now struct timespec, so that we can support
10016 ns-resolution time stamps.
10017 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10018 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10019 (EMACS_USECS): Remove.
10020 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10021 so multiply the arg by 1000 before storing it.

10031 (make_timeval, make_lisp_time, decode_time_components): New decls.
10032 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10033 that it mishandled time_t overflow. You can't compare by subtracting!
10034 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10035 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10037 * term.c: Include <sys/time.h>.
10038 (timeval_to_Time): New function, for proper overflow wraparound.
10039 (term_mouse_position, term_mouse_click): Use it.

10042 in the undo buffer.
10043 (Fprimitive_undo): Use them when restoring time stamps.
10045 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10046 (w32_get_internal_run_time):
10047 Port to higher-resolution Emacs time stamps.
10048 (ltime): Now accepts single 64-bit integer, as that's more convenient
10051 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10053 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10054 for compatibility with pselect. Support ns-resolution time stamps.
10056 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10058 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10059 Check for time stamp overflow, and support ns-resolution time stamps.
10061 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10062 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10063 (timeval_subtract): Remove; no longer needed.
10064 (XTflash, XTring_bell, x_wait_for_event):
10065 Port to ns-resolution time stamps. Don't assume time_t is signed.

10074 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10075 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10076 staticidx goes up to 1597 out of 1600 = 0x640.)
10078 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10080 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10081 Otherwise, the umask might be mistakenly 0 while handling input signals.
10083 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10085 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10101 frame's selected window and its terminal's top-frame.
10102 (unwind_format_mode_line): Restore them.
10103 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10105 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10106 since tty frames can be explicitly named.
10107 (prepare_menu_bars): Likewise.
10109 * term.c (Ftty_top_frame): New function.
10111 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10113 Port byte-code-meter to modern targets.
10114 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10115 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10116 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10117 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10124 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10126 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10127 gets killed during executing of this function (Bug#11665).
10128 Try to always return Qt when the buffer has been actually killed.
10129 (Vkill_buffer_query_functions): In doc-string say that functions
10130 run by this hook should not change the current buffer.
10132 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10134 Fix recently-introduced process.c problems found by static checking.
10135 * process.c (write_queue_push, write_queue_pop, send_process):

10154 * lisp.h (eassert): Assume C89 or later.
10155 This removes the need for CHECK.
10156 (CHECK): Remove. Its comments about always evaluating its
10157 argument were confusing, as 'eassert' typically does not evaluate
10160 * coding.c (produce_chars): Use ptrdiff_t, not int.
10162 * xterm.c (x_draw_underwave): Check for integer overflow.
10163 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10351 Use an inline function on all platforms when using the union type,

10438 * xdisp.c (vmessage): Treat frame message as multibyte.
10439 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10440 would generate the diagnostic "Making \302\247 buffer-local while

10445 * dispnew.c (showing_window_margins_p): Undo last change, which
10446 was done due to an inadvertent commit.
10447 (adjust_frame_glyphs_for_frame_redisplay): Do call
10448 showing_window_margins_p.

10458 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
10459 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
10461 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10463 * alloc.c (allocate_vectorlike): Fix last change.
10465 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
10467 Block-based vector allocation of small vectors.
10468 * lisp.h (struct vectorlike_header): New field `nbytes',
10469 adjust comment accordingly.
10470 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10471 to denote vector blocks. Adjust users (live_vector_p,
10472 mark_maybe_pointer, valid_lisp_object_p) accordingly.
10473 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
10474 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

10487 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
10488 (init_alloc_once): Add call to init_vectors.
10490 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
10492 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
10494 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10496 * doprnt.c (doprnt): Truncate multibyte char correctly.
10497 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10498 would mishandle a string argument "Xc" if X was a multibyte
10499 character of length 2: it would truncate after X's first byte
10500 rather than including all of X.
10502 2012-06-06 Chong Yidong <cyd@gnu.org>
10504 * buffer.c (word_wrap): Doc fix.
10506 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10518 binary via PaX flags if the paxctl utility is available.
10519 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10520 Restore PaX flags to their default. (Bug#11398)
10522 2012-06-03 Chong Yidong <cyd@gnu.org>
10524 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10525 buffer (Bug#11226).

10530 (note_mode_line_or_margin_highlight): If there is no help echo,
10531 use mode-line-default-help-echo. Handle the case where the mouse
10532 position is past the end of the mode line string.
10534 * buffer.c (buffer_local_value_1): New function, split from
10535 Fbuffer_local_value; can return Qunbound.
10536 (Fbuffer_local_value): Use it.
10537 (Vmode_line_format): Docstring tweaks.
10539 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10551 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10553 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10554 Convert pctcpu and pctmem to Lisp float properly.
10555 Let the compiler fold better, as 100.0/0x8000 is exact.
10557 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10559 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10562 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10566 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10568 For a 'struct window', replace some Lisp_Object fields to
10569 bitfields where appropriate, remove unused fields.
10570 * window.h (struct window): Remove unused 'last_mark_x' and
10571 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10572 change its type from Lisp_Object to bitfield.
10573 Change type of 'force_start', 'optional_new_start',
10574 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10575 fields from Lisp_Object to bitfield. Adjust users accordingly.
10577 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10579 Pacify gcc -Wdouble-precision when using Xaw.
10580 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10581 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10582 Use 'float' consistently, rather than 'float' in most places
10583 and 'double' in a couple of places.
10585 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10587 * xdisp.c (handle_stop): Detect whether we have overlay strings
10588 loaded by testing it->current.overlay_string_index to be
10589 non-negative, instead of checking whether n_overlay_strings is
10590 positive. (Bug#11587)
10592 2012-05-31 Chong Yidong <cyd@gnu.org>
10594 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10598 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10600 * search.c (search_buffer): Remove calls to
10601 r_alloc_inhibit_buffer_relocation, as it is now called by
10602 maybe_unify_char, which was the cause of relocation of buffer text
10605 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10607 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10608 for the duration of call to load_charset, to avoid problems with
10609 callers of maybe_unify_char that access buffer text through C
10612 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10613 decrement the inhibition flag, instead of just setting or
10616 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10618 Remove obsolete '#define static' cruft.
10619 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10620 This #undef was "temporary" in 2000; it is no longer needed
10621 now that '#define static' has gone away.
10622 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10623 (gray_bitmap_bits): Remove; no longer needed.
10624 All uses replaced with definiens.
10625 * xterm.c: Include "bitmaps/gray.xbm".
10627 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

10630 The following changes affect the code only when profiling.
10631 * dispnew.c (__executable_start): Rename from safe_bcopy.
10632 Define only on platforms that need it.
10633 * emacs.c: Include <sys/gmon.h> when profiling.
10634 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10635 (__executable_start): Remove decl, since lisp.h does it now.
10636 (safe_bcopy): Remove decl; no longer has that name.
10637 (main): Coalesce #if into single bit of code, for simplicity.
10638 Cast pointers to uintptr_t, since standard libraries want integers
10640 * lisp.h (__executable_start): New decl.
10642 2012-05-31 Glenn Morris <rgm@gnu.org>
10644 * image.c (Fimagemagick_types): Doc fix.

10665 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10667 Do not create empty overlays with the evaporate property (Bug#9642).
10668 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10669 Bug#9642, but explicitly check that the buffer the overlay would
10670 be moved to is live and rearrange lines to make sure that errors
10671 will not put the overlay in an inconsistent state.
10672 (Fdelete_overlay): Cosmetics.
10674 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10676 * w32term.c (my_bring_window_to_top): New function.
10677 (x_raise_frame): Use handle returned by DeferWindowPos, which
10678 could be different from the original one.
10679 Call my_bring_window_to_top instead of my_set_foreground_window.

10688 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10690 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10691 This avoids undefined behavior that might cause the eassert
10692 to not catch an out-of-range value.
10694 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10696 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10697 Update dependencies.
10699 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10701 * bidi.c (bidi_mirror_char): Fix last change.
10703 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10708 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10710 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10711 Only r_alloc_inhibit_buffer_relocation needed to be added;
10712 the others were already declared.
10714 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10715 before checking whether it's out of range. Put the check inside
10717 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10719 2012-05-27 Ken Brown <kbrown@cornell.edu>
10721 * callproc.c (Fcall_process): Restore a line that was accidentally
10722 commented out in the 2011-02-13 change (bug#11547).
10724 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10726 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10727 defined on ralloc.c.
10729 * buffer.c [REL_ALLOC]: Remove prototypes of
10730 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10731 they are now on lisp.h.
10733 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10735 * search.c (search_buffer): Use it to inhibit relocation of buffer
10736 text while re_search_2 is doing its job, because re_search_2 is
10737 passed C pointers to buffer text. (Bug#11519)
10739 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10740 Update value to 24.
10742 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10743 state after an additional call to move_it_in_display_line_to, keep
10744 the values of it->max_ascent and it->max_descent found for the
10746 (pos_visible_p): Revert the comparison against bottom_y to what it
10747 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10750 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10752 Fix coding-related core dumps with gcc -ftrapv.
10753 The code was computing A - B, where A and B are pointers, and B is
10754 random garbage. This can lead to core dumps on platforms that
10755 have special pointer registers, and it also leads to core dumps on
10756 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10757 A - B only when B is initialized properly.
10758 * coding.c (coding_set_source, coding_set_destination): Return void.
10759 (coding_change_source, coding_change_destinations): New functions,
10760 with the old behaviors of coding_set_source and coding_set_destination.
10761 All callers that need an offset changed to use these new functions.
10763 2012-05-26 Glenn Morris <rgm@gnu.org>
10765 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10767 2012-05-26 Eli Zaretskii <eliz@gnu.org>

10770 * xdisp.c (draw_row_with_mouse_face):
10771 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10773 * w32console.c: Include window.h.
10774 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10776 (initialize_w32_display): Initialize mouse-highlight data.
10778 * w32inevt.c: Include termchar.h and window.h.
10779 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10780 moves, call note_mouse_highlight. If help_echo changed, call
10781 gen_help_event to produce help-echo message in the echo area.
10782 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10785 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10787 * lread.c (read1): Simplify slightly to avoid an overflow warning
10788 with GCC 4.7.0 on x86-64.
10790 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10792 * bidi.c (bidi_mirror_char): Revert last change: an int is
10793 definitely wide enough here.
10795 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10797 Fix integer width and related bugs (Bug#9874).

10804 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10805 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10807 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10808 (allocate_pseudovector):
10809 Use int, not EMACS_INT, where int is wide enough.
10810 (inhibit_garbage_collection, Fgarbage_collect):
10811 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10812 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10813 int might not be wide enough.
10814 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10815 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10816 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10817 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10818 (bidi_level_of_next_char, bidi_move_to_visually_next):
10819 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10820 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10821 (Fkill_buffer, Fset_buffer_major_mode)
10822 (advance_to_char_boundary, Fbuffer_swap_text)
10823 (Fset_buffer_multibyte, overlays_at, overlays_in)
10824 (overlay_touches_p, struct sortvec, record_overlay_string)
10825 (overlay_strings, recenter_overlay_lists)
10826 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10827 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

10829 (Foverlay_recenter, last_overlay_modification_hooks_used)
10830 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10831 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10832 (validate_region): Omit unnecessary test for b <= e,
10833 since that's guaranteed by the previous test.
10834 (adjust_overlays_for_delete): Avoid pos + length overflow.
10835 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10836 (report_overlay_modification):
10837 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10838 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10839 Omit pointer cast, which isn't needed anyway, and doesn't work
10840 after the EMACS_INT -> ptrdiff_t change.
10841 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10842 * buffer.h: Adjust decls to match defn changes elsewhere.
10843 (struct buffer_text, struct buffer):
10844 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10845 Use EMACS_INT, not int, where int might not be wide enough.
10846 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10847 not int, to avoid needless 32-bit limit on 64-bit hosts.
10848 (exec_byte_code): Use tighter memory-full test, one that checks
10849 for alloca overflow. Don't compute the address of the object just
10850 before an array, as that's not portable. Use EMACS_INT, not
10851 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10852 * callint.c (Fcall_interactively):
10853 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10854 * callproc.c (call_process_kill, Fcall_process):
10855 Don't assume pid_t fits into an Emacs fixnum.

10864 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10865 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10866 (casify_object): Avoid integer overflow when overallocating buffer.
10867 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10868 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

10870 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10871 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10872 integers are now checked earlier. All uses replaced with XINT.
10874 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10875 For CCL_MapSingle, check that content and value are in int range.
10876 (ccl_driver, Fregister_code_conversion_map):
10877 Check that Vcode_version_map_vector is a vector.
10878 (resolve_symbol_ccl_program): Check that vector header is in range.
10879 Always copy the vector, so that we can check its contents reliably
10880 now rather than having to recheck each instruction as it's being
10881 executed. Check that vector words fit in 'int'.
10882 (ccl_get_compiled_code, Fregister_ccl_program)
10883 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10884 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10885 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10886 contents are in range.
10887 (Fccl_execute_on_string): Check that status is in range.
10888 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10889 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

10896 (string_escape_byte8, Fget_byte):
10897 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10898 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10899 avoid mishandling large integers.

10901 * charset.c (load_charset_map_from_file, find_charsets_in_text)

10909 (Fdefine_charset_internal): Check ranges here, more carefully.
10910 Don't rely on undefined behavior with signed left shift overflow.
10911 Don't assume unsigned int fits into fixnum, or that fixnum fits
10912 into unsigned int. Don't require max_code to be a valid fixnum;
10913 that's not true for gb10830 4-byte on a 32-bit host. Allow
10914 invalid_code to be a cons, for the same reason. Require code_offset
10915 to be a character. Avoid int overflow if max_char is close
10917 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10918 this is intended anyway and avoids some undefined behavior.
10919 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10920 INDEX_TO_CODE_POINT, as that's what it expects.
10921 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10922 * charset.h (DECODE_CHAR): Return int, not unsigned;
10923 this is what was intended anyway, and it avoids undefined behavior.

10925 integer-overflow issues.
10926 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10927 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10928 where the argument is EMACS_INT, and this behavior is not intended.
10929 * chartab.c (Fmake_char_table, Fset_char_table_range)
10930 (uniprop_get_decoder, uniprop_get_encoder):
10931 Don't assume fixnum fits in int.
10932 * cmds.c (move_point): New function, that does the gist of
10933 Fforward_char and Fbackward_char, but does so while checking
10934 for integer overflow more accurately.
10935 (Fforward_char, Fbackward_char): Use it.
10936 (Fforward_line, Fend_of_line, internal_self_insert)
10937 (internal_self_insert):
10938 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11540 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
11541 (handle_tool_bar_click):
11542 Use int, not unsigned, since we prefer signed and the signedness
11543 doesn't matter here.
11544 (get_next_display_element, next_element_from_display_vector):
11545 Use int, not EMACS_INT, when int is wide enough.
11546 (start_hourglass): Use duration_to_sec_usec to do proper
11547 overflow checking on durations.
11548 * xfaces.c (Fbitmap_spec_p):
11549 Check that fixnums are in proper range for system types.
11550 (compare_fonts_by_sort_order):
11551 Avoid mishandling comparisons due to subtraction overflow.
11552 (Fx_family_fonts, realize_basic_faces):
11553 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11555 Don't assume fixnum fits in int.
11556 Use SAFE_ALLOCA_LISP, not alloca.
11557 (merge_face_heights): Remove unnecessary cast to EMACS_INT.

11566 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
11567 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):

11569 (Fx_change_window_property): Don't assume fixnums fit in int.
11570 * xfont.c (xfont_chars_supported):
11571 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

11579 (x_get_local_selection, x_reply_selection_request)
11580 (x_handle_selection_request, wait_for_property_change):
11581 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11582 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
11583 short is wide enough.
11584 (x_send_client_event): Don't assume fixnum fits in int.
11585 * xterm.c (x_x_to_emacs_modifiers):
11586 Don't assume EMACS_INT overflows nicely into int.
11587 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11588 may come from Lisp.
11589 (handle_one_xevent): NATNUMP can eval its arg twice.
11590 (x_connection_closed):
11591 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11592 * xterm.h: Adjust decls to match defn changes elsewhere.
11593 (struct scroll_bar): Use struct vectorlike_header
11594 rather than rolling our own approximation.
11595 (SCROLL_BAR_VEC_SIZE): Remove; not used.
11597 2012-05-25 Glenn Morris <rgm@gnu.org>
11599 * lisp.mk (lisp): Update for more files being compiled now.
11601 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11603 * lread.c: Remove `read_pure' which makes no difference.
11604 (read_pure): Remove var.
11605 (unreadpure): Remove function.
11606 (readevalloop): Don't call read_list with -1 flag.
11607 (read1, read_vector): Don't test read_pure any more.
11608 (read_list): Simplify.
11610 * fileio.c, character.h: Minor style tweaks.
11612 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
11614 * window.h (clip_changed): Remove useless declaration.
11616 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11618 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11619 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11621 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11624 This directory predates autoconf and is no longer needed nowadays.
11625 Move its few remaining bits of functionality to where they're needed.
11626 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11627 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11628 * m/template.h: Remove.
11629 * Makefile.in (M_FILE): Remove. All uses removed.
11630 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11631 * lisp.h (USE_LSB_TAG):
11632 * mem-limits.h (EXCEEDS_LISP_PTR):
11633 Use VAL_MAX, not VALBITS, in #if.
11634 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11635 (EMACS_UINT): Define unconditionally now.
11636 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11637 (BITS_PER_EMACS_INT): New constants, replacing
11638 what used to be in config.h, but not useful in #if.
11639 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11640 define them any more.
11641 (VAL_MAX): New macro.
11643 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11644 BITS_PER_EMACS_INT, in #if.
11645 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11646 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11647 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11648 * s/ms-w32.h (DATA_START):
11649 Move here from removed file m/intel386.h.
11650 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11651 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11653 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11655 Assume C89 or later.
11656 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11657 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11659 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

11665 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11666 * xterm.c (input_signal_count): Assume volatile works.
11668 2012-05-21 Ken Brown <kbrown@cornell.edu>
11670 * xgselect.c (xg_select): Fix first argument in call to 'select'
11673 2012-05-20 Ken Brown <kbrown@cornell.edu>

11676 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11678 2012-05-19 Ken Brown <kbrown@cornell.edu>
11680 * xfns.c (x_in_use): Remove `static' qualifier.
11681 * xterm.h (x_in_use): Declare.
11682 * xgselect.c: Include xterm.h.
11683 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11684 and `display_arg' (bug#9754).
11686 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11688 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11690 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11691 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11693 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11695 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11697 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11698 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11700 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11701 reference to image_cache->refcount.
11702 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11704 2012-05-17 Juri Linkov <juri@jurta.org>
11706 * search.c (Fword_search_regexp, Fword_search_backward)
11707 (Fword_search_forward, Fword_search_backward_lax)
11708 (Fword_search_forward_lax): Move functions to isearch.el
11709 (bug#10145, bug#11381).
11711 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11713 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11715 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11717 * lread.c (init_obarray): Declare Qt and Qnil as special.
11719 2012-05-14 Glenn Morris <rgm@gnu.org>
11721 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11722 Put "libexec" before "bin", for the sake of init_callproc_1.
11724 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11726 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11728 * unexaix.c: Port to more-recent AIX compilers.
11729 (report_error, report_error_1, make_hdr, copy_sym)
11730 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11731 Make arguments const char *, not char *, to avoid violations of C
11732 standard and to fix some AIX warnings reported by Gilles Pion.
11734 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11736 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11737 already have overlays loaded.
11738 (handle_single_display_spec): Before returning without displaying
11739 fringe bitmap, synchronize the bidi iterator with the main display
11740 iterator, by calling iterate_out_of_display_property.
11741 (iterate_out_of_display_property): Detect buffer iteration by
11742 testing that it->string is a Lisp string.
11743 (get_next_display_element): When the current object is exhausted,
11744 and there's something on it->stack, call set_iterator_to_next to
11745 proceed with what's on the stack, instead of returning zero.
11746 (set_iterator_to_next): If called at the end of a Lisp string,
11747 proceed to consider_string_end without incrementing string
11748 position. Don't increment display vector index past the end of
11749 the display vector. (Bug#11417)
11750 (pos_visible_p): Don't report a position visible when move_it_to
11751 stopped at the last line of window, which happens to be scanned
11752 backwards by the bidi iteration. (Bug#11464)
11754 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11756 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11757 and right-margin display specs even if the spec is invalid or we
11758 are on a TTY, and thus unable to display on the fringes.
11759 That's because the text with the property will not be displayed anyway,
11760 so we need to signal to the caller that this is a "replacing"
11761 display spec. This fixes display when the spec is invalid or we
11764 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11766 * unexaix.c (make_hdr): Fix typo in prototype.
11767 This bug broke the build on AIX. Problem reported by Gilles Pion.
11769 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11771 * keyboard.c (kbd_buffer_get_event): Read special events also in
11772 batch mode. (Bug#11415)
11774 2012-05-12 Glenn Morris <rgm@gnu.org>
11776 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11778 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11780 * lisp.mk (lisp): Add newcomment.elc.
11782 2012-05-12 Glenn Morris <rgm@gnu.org>
11784 * Makefile.in (MKDIR_P): New, set by configure.
11785 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11787 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11789 Remove unused function hourglass_started.
11790 * dispextern.h (hourglass_started):
11791 * w32fns.c (hourglass_started):
11792 * xdisp.c (hourglass_started): Remove.
11794 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11796 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11797 Update dependencies.
11799 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11801 * xgselect.c (xg_select): Put maxfds+1 into a var.
11802 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11804 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11806 2012-05-10 Dave Abrahams <dave@boostpro.com>
11808 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11809 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11811 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11813 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11814 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11815 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11816 Initialize xd_registered_buses.
11818 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11820 Untag more efficiently if USE_LSB_TAG.
11821 This is based on a proposal by YAMAMOTO Mitsuharu in
11822 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11823 For an admittedly artificial (nth 8000 longlist) benchmark on
11824 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11825 Emacs's overall text size by 1%.
11826 * lisp.h (XUNTAG): New macro.
11827 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11828 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11829 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11830 * eval.c (Fautoload):
11831 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11832 * frame.h (XFRAME): Use XUNTAG.
11834 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11835 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11836 Remove unportable assumptions about print widths of types like
11838 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11839 intptr_t when converting between pointer and integer, to avoid GCC
11840 warnings about wrong width.
11842 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11844 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11845 stack for each reader_thread, instead of defaulting to 8MB
11846 determined by the linker. This avoids failures in creating
11847 subprocesses on Windows 7, see the discussion in this thread:
11848 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11850 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11852 Fix up display of the *Minibuf-0* buffer in the mini window.
11853 * keyboard.c (read_char): Don't clear the echo area if there's no
11855 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11856 contents of *Minibuf-0*) if there's no message displayed in its stead.
11858 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11860 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11863 2012-05-06 Chong Yidong <cyd@gnu.org>
11865 * lisp.mk (lisp): Update.
11867 2012-05-05 Jim Meyering <meyering@redhat.com>
11869 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11871 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11873 * data.c (PUT_ERROR): New macro.
11874 (syms_of_data): Use it. Add new error type `user-error'.
11875 * undo.c (user_error): New function.
11876 (Fprimitive_undo): Use it.
11877 * print.c (print_error_message): Adjust print style for `user-error'.
11878 * keyboard.c (user_error): New function.
11879 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11881 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11883 Do not limit current-time-string to years 1000..9999.
11884 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11885 (Fcurrent_time_string): Support any year that is supported by the
11886 underlying localtime representation. Don't use asctime, as it
11887 has undefined behavior for years outside the range -999..9999.
11889 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11891 Fix race conditions involving setenv, gmtime, localtime, asctime.
11892 Without this fix, interrupts could mess up code that uses these
11893 nonreentrant functions, since setting TZ invalidates existing
11894 tm_zone or tzname values, and since most of these functions return
11895 pointers to static storage.
11896 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11897 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11898 Grow the critical sections to include not just invoking
11899 localtime/gmtime, but also accessing these functions' results
11900 including their tm_zone values if any, and any related TZ setting.
11901 (format_time_string): Last arg is now struct tm *, not struct tm **,
11902 so that the struct tm is saved in the critical section.
11903 All callers changed. Simplify allocation of initial buffer, partly
11904 motivated by the fact that memory allocation needs to be outside
11905 the critical section.
11907 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11909 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11910 with RESET_INTERVAL.
11912 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11913 Remove duplicated buffer name initialization.
11915 2012-05-02 Jim Meyering <jim@meyering.net>
11917 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11919 * xfns.c (x_window): Use xstrdup (Bug#11375).
11921 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11923 * xdisp.c (pos_visible_p): If already at a newline from the
11924 display string before the 'while' loop, don't walk back the glyphs
11925 from it3.glyph_row. Solves assertion violation when the display
11926 string begins with a newline (egg.el). (Bug#11367)
11928 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11930 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11933 2012-05-01 Glenn Morris <rgm@gnu.org>
11935 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11936 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11937 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11938 All were removed before 23.1.
11940 * dispnew.c: Remove HAVE_LIBNCURSES test;
11941 it is always true on relevant platforms.
11943 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11944 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11946 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11948 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11950 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11951 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11954 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11956 Do not avoid creating empty evaporating overlays (Bug#9642).
11957 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11958 That is, do not delete an evaporating overlay if it becomes
11959 empty after its bounds are adjusted to fit within its buffer.
11960 This fix caused other problems, and I'm reverting it until we get
11961 to the bottom of them.
11963 2012-04-27 Chong Yidong <cyd@gnu.org>
11965 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11967 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11969 * xdisp.c (pos_visible_p): If the window start position is beyond
11970 ZV, start the display from buffer beginning. Prevents assertion
11971 violation in init_iterator when the minibuffer window is scrolled
11972 via the scroll bar.
11974 * window.c (window_scroll_pixel_based): Likewise.
11976 2012-04-27 Chong Yidong <cyd@gnu.org>

11983 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11985 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11987 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11988 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11990 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11992 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11993 display element, check also the underlying string or buffer
11994 character. (Bug#11341)
11996 * w32menu.c: Include w32heap.h.
11997 (add_menu_item): If the call to AppendMenuW (via
11998 unicode_append_menu) fails, disable Unicode menus only if we are
11999 running on Windows 9X/Me.
12001 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12003 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12004 (xgetint): Add missing shift for LSB tags.

12020 now a cons (bug#11311).
12022 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12024 Do not create empty overlays with the evaporate property (Bug#9642).
12025 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12026 if it becomes empty after its bounds are adjusted to fit within
12027 its buffer. Without this fix, in a nonempty buffer (let ((o
12028 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12029 yields an empty overlay that has the evaporate property, which is
12030 not supposed to happen.

12147 * sysdep.c [__FreeBSD__]: Minor cleanups.
12148 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12149 Use Emacs indenting style more consistently. Avoid some casts.

12164 It is never used otherwise.
12166 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12168 * print.c (print_preprocess): Only check print_depth if print-circle

12175 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12176 set the status to "failed" and ensure that sentinel is run.
12178 2012-04-20 Glenn Morris <rgm@gnu.org>
12180 * process.c (Fset_process_inherit_coding_system_flag)

12231 New extern decls, to avoid calling undeclared functions.
12232 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12233 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12234 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12235 (NEED_MEM_INSERT): New macro.
12236 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12237 Remove one incorrect comment and fix another.

12273 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12274 * s/netbsd.h, s/sol2-6.h:
12275 Remove definition of GC_MARK_STACK, since the default now works.
12276 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12304 2012-04-11 Daniel Colascione <dancol@dancol.org>
12306 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12307 against is gone. It's better to use vfork now so that when Cygwin
12308 gains a new, working vfork, we use it automatically (bug#10398).
12310 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12351 (emacs_gnutls_read): Use new log functions,
12352 `gnutls_handshakes_tried' process member, and
12353 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12354 attempts per process (connection).
12356 2012-04-09 Chong Yidong <cyd@gnu.org>

12360 (Fdefvar): Caller changed.
12362 * callint.c (Finteractive, Fcall_interactively):
12363 * minibuf.c (Fread_variable): Callers changed.
12365 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12367 * xdisp.c (set_cursor_from_row): If the display string appears in
12368 the buffer at position that is closer to point than the position
12369 after the display string, display the cursor on the first glyph of
12370 the display string. Fixes cursor display when a 'display' text
12371 property immediately follows invisible text. (Bug#11094)
12373 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12375 composite.c: use 'double' consistently
12376 * composite.c (get_composition_id): Use 'double' consistently
12377 instead of converting 'float' to 'double' and vice versa; this is
12378 easier to understand and avoids a GCC warning.
12380 2012-04-09 Glenn Morris <rgm@gnu.org>
12382 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12383 preparation for dumping it with emacs. (Bug#4789)

12404 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12405 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12406 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12407 objects, as mark_maybe_pointer will catch them otherwise.
12408 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12409 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12427 [!WINDOWSNT]: New macros.
12428 (init_libxml2_functions, libxml2_loaded_p): New functions.
12429 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12430 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12431 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12432 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12434 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12435 Call init_libxml2_functions before calling libxml2 functions.
12436 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12438 * emacs.c: Don't include libxml/parser.h.
12439 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12440 xmlCleanupParser directly.
12442 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12444 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12446 * indent.c (Fvertical_motion): If there is a display string at
12447 point, use it.vpos to compute how many lines to backtrack after
12448 move_it_to point. (Bug#11133)
12450 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12452 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12453 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12454 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12455 macros related to unification of CJK characters. For the details,
12456 see the discussion following the message here:
12457 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12459 2012-04-04 Chong Yidong <cyd@gnu.org>
12461 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12463 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12465 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12466 instead of alloca. (Bug#11138)
12468 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

12473 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12475 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12476 position we get to after a call to move_it_to fails the
12477 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12478 only if we wind up in a string from display property. (Bug#11063)
12480 * window.c (Fdelete_other_windows_internal): Invalidate the row
12481 and column information about mouse highlight, so that redisplay
12482 restores it after reallocating the glyph matrices. (Bug#7464)
12484 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12485 string comes from a `display' text property, use the buffer
12486 position of that property as if we actually saw that position in
12488 (move_it_by_lines): Remove the assertion that
12489 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12490 violated when there's a before-string at the beginning of a line.
12493 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12495 * xdisp.c (append_space_for_newline): If the default face was
12496 remapped, use the remapped face for the appended newline.
12497 (extend_face_to_end_of_line): Use the remapped default face for
12498 extending the face to the end of the line.
12499 (display_line): Call extend_face_to_end_of_line when the default
12500 face was remapped. (Bug#11068)
12502 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12504 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12506 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12508 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12510 2012-03-27 Glenn Morris <rgm@gnu.org>
12512 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12515 2012-03-26 Kenichi Handa <handa@m17n.org>

12522 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12523 (command_loop_1): Use it; inhibit selection update for
12524 handle-select-window too (Bug#8996).
12526 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12528 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12530 2012-03-25 Kenichi Handa <handa@m17n.org>
12532 * dispextern.h (struct glyph): Change the bit length of
12533 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12535 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12537 * s/ms-w32.h (tzname): Include time.h before redirecting to
12538 _tzname. Fixes the MSVC build. (Bug#9960)
12540 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12542 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12545 * xterm.c (XTread_socket): Only modify handling_signal if
12546 !SYNC_INPUT. (Bug#11080)
12548 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12550 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12551 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12552 when fetching a multibyte character consumes more bytes than
12553 CHAR_BYTES returns, due to unification of CJK characters in
12554 string_char. (Bug#11073)
12556 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12558 * process.c (wait_reading_process_output): Handle pty disconnect
12559 by refraining from sending oneself a SIGCHLD (bug#10933).

12567 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12568 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12570 2012-03-21 Chong Yidong <cyd@gnu.org>
12572 * xfaces.c (Vface_remapping_alist): Doc fix.
12574 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12576 * w32proc.c (Fw32_set_console_codepage)
12577 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

12582 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12583 to reflect default non-nil value of redisplay-dont-pause.
12585 2012-03-19 Kenichi Handa <handa@m17n.org>
12587 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12588 it fit in a valid range (Bug#11003).
12590 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12592 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12593 that is not from display property, accept the row as a "cursor
12594 row" if one of the string's character has a non-nil `cursor'
12595 property. Fixes cursor positioning when there are newlines in
12596 overlay strings, e.g. in icomplete.el. (Bug#11035)
12598 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12600 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12602 2012-03-12 Chong Yidong <cyd@gnu.org>
12604 * eval.c (inhibit_lisp_code): Rename from
12605 inhibit_window_configuration_change_hook; move from window.c.
12607 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12608 * window.c (run_window_configuration_change_hook)
12609 (syms_of_window): Callers changed.

12629 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12632 2012-03-03 Glenn Morris <rgm@gnu.org>
12634 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12636 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12638 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12639 position past the first glyph_row that ends at ZV. (Bug#10902)
12640 (redisplay_window, next_element_from_string): Fix typos in
12642 (redisplay_window): Pass to move_it_vertically the margin in
12643 pixels, not in screen lines.
12645 2012-03-02 Glenn Morris <rgm@gnu.org>
12647 * buffer.c (buffer-list-update-hook): Doc fix.
12649 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12651 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12652 push_it before setting up the iterator for the first overlay
12653 string, even if we have an empty string loaded.
12654 (next_overlay_string): If there's an empty string on the iterator
12655 stack, pop the stack. (Bug#10903)
12657 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12659 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12660 Suggested by Stefan Monnier in
12661 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12662 * alloc.c (widen_to_Lisp_Object): New static function.
12663 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12664 and widening them to Lisp_Objects. This would work even if
12665 USE_LSB_TAG is defined and wide integers are used, which might
12666 happen in a future version of Emacs.
12668 2012-02-25 Chong Yidong <cyd@gnu.org>
12670 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12673 * xselect.c (Fx_selection_exists_p): Doc fix.

12675 before saving to clipboard manager.
12677 2012-02-24 Chong Yidong <cyd@gnu.org>
12679 * keyboard.c (process_special_events): Handle all X selection
12680 requests in kbd_buffer, not just the next one (Bug#8869).

12707 when computing $valmask.
12709 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12710 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12711 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12712 It's useless in that case, and it can cause problems on hosts
12713 that allocate halves of EMACS_INT values separately.
12714 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12715 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12716 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12717 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12718 it avoids undefined behavior on hosts where shifting right by more
12719 than the word width has undefined behavior.
12721 2012-02-19 Chong Yidong <cyd@gnu.org>
12723 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12724 (Funhandled_file_name_directory, Ffile_name_as_directory)
12725 (Fdirectory_file_name, Fexpand_file_name)

12741 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12743 2012-02-15 Chong Yidong <cyd@gnu.org>
12745 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12746 marked as special. Also, starting docstrings with * is obsolete.

12761 2012-02-12 Chong Yidong <cyd@gnu.org>
12763 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12764 as that creates a dangerous corner case.
12766 * window.c (Fdelete_window_internal): Invalidate the mouse
12767 highlight (Bug#9904).
12769 2012-02-12 Glenn Morris <rgm@gnu.org>

12772 (Fx_get_selection_internal, Fx_disown_selection_internal)
12773 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12774 * nsselect.m (Fx_own_selection_internal)
12775 (Fx_disown_selection_internal, Fx_selection_exists_p)
12776 (Fx_selection_owner_p, Fx_get_selection_internal):
12777 Sync docs and argument specs with the xselect.c versions.
12779 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12781 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

12799 2012-02-07 Chong Yidong <cyd@gnu.org>
12801 * buffer.c (Fbuffer_local_variables)
12802 (buffer_lisp_local_variables): Handle unbound vars correctly;
12803 don't let Qunbound leak into Lisp.
12805 2012-02-07 Glenn Morris <rgm@gnu.org>
12807 * image.c (Fimagemagick_types): Doc fix.
12809 * image.c (imagemagick-render-type): Change it from a lisp object
12810 to an integer. Move the doc here from the lisp manual.
12811 Treat all values not equal to 0 the same.
12813 2012-02-06 Chong Yidong <cyd@gnu.org>
12815 * doc.c (store_function_docstring): Avoid applying docstring of

12839 * keyboard.c (adjust_point_for_property): Don't position point
12840 before BEGV. (Bug#10696)
12842 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12844 Handle overflow when computing char display width (Bug#9496).
12845 * character.c (char_width): Return EMACS_INT, not int.
12846 (char_width, c_string_width): Check for overflow when
12847 computing the width; this is possible now that individual
12848 characters can have unbounded width. Problem introduced
12849 by merge from Emacs 23 on 2012-01-19.
12851 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13384 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
13385 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
13386 this macro definition.
13388 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
13391 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

13413 * xdisp.c (redisplay_window): If cursor row is not fully visible
13414 after recentering, and scroll-conservatively is set to a large
13415 number, scroll window by a few more lines to make the cursor fully
13416 visible and out of scroll-margin. (Bug#10105)
13417 (start_display): Don't move to the next line if the display should
13418 start at a newline that is part of a display vector or an overlay
13419 string. (Bug#10119)

13499 Otherwise, valgrind does not work on some platforms.
13500 Problem reported by Andreas Schwab in
13501 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13502 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13503 is set, removing the need for VIRT_ADDRESS_VARIES.
13504 (PURE_P): Use a more-efficient implementation that needs just one
13505 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13506 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13507 to 4 (xorl, subq, cmpq, setbe).
13508 * alloc.c (pure): Always extern now, since that's the
13509 VIRT_ADDR_VARIES behavior.
13510 (PURE_POINTER_P): Use a single comparison, not two, for
13511 consistency with the new puresize.h.
13512 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13513 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13519 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13520 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13521 behave as if the cursor position were at the window margin.
13523 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13524 and the cursor position is out of bounds, behave as if the cursor
13525 position were at the window margin. (Bug#10075)
13527 2011-11-18 Chong Yidong <cyd@gnu.org>
13529 * window.c (Fwindow_combination_limit): Make first argument

13548 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13550 * xdisp.c (row_hash): New function, body extracted from
13551 compute_line_metrics.
13552 (compute_line_metrics): Call row_hash, instead of computing the
13555 * dispnew.c (verify_row_hash): Call row_hash for computing the
13556 hash code of a row, instead of duplicating code from xdisp.c.
13558 * dispextern.h (row_hash): Add prototype.
13560 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13562 * frame.c (delete_frame): Don't delete the terminal when the last

13587 (recombine_windows, make_parent_window, make_window)
13588 (Fsplit_window_internal, saved_window)
13589 (Fset_window_configuration, save_window_save): Rename all
13590 occurrences of window_nest to window_combination_limit.
13592 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

13596 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13598 * xdisp.c (display_line): Move the call to
13599 highlight_trailing_whitespace before the call to
13600 compute_line_metrics, since the latter needs to see the final
13601 faces of all the glyphs to compute ROW's hash value.
13602 Fixes assertion violations in row_equal_p. (Bug#10035)
13604 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13606 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13607 just return (bug#10044).
13609 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13611 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13612 with user-defined heap size. Bump the default size of the temacs
13613 heap to 27MB, to avoid memory warning when running temacs.
13614 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13616 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13617 current_matrix and desired_matrix. (Bug#9990)
13618 (verify_row_hash) [XASSERTS]: New function.
13619 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13620 that the hash value of glyph rows is correct.

13652 avoid a crash (bug#9496).
13654 2011-11-09 Chong Yidong <cyd@gnu.org>
13656 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13663 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13665 Avoid some portability problems by eschewing 'extern inline' functions.
13666 The trivial performance wins aren't worth the portability hassles; see
13667 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13669 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13670 (window_box_width, window_box_left, window_box_left_offset)
13671 (window_box_right, window_box_right_offset): Undo previous change,
13672 by removing the "extern"s.
13673 * intervals.c (adjust_intervals_for_insertion)
13674 (adjust_intervals_for_deletion): Undo previous change,
13675 making these static again.
13676 (offset_intervals, temp_set_point_both, temp_set_point)
13677 (copy_intervals_to_string): No longer inline.
13678 * xdisp.c (window_text_bottom_y, window_box_width)

13717 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
13718 This is also needed for porting to any host where GC_MARK_STACK is
13719 not GC_MAKE_GCPROS_NOOPS.
13720 (which_symbols): Use it.
13722 2011-11-07 Kenichi Handa <handa@m17n.org>
13724 * coding.c (coding_set_destination): Check coding->src_pos only

13735 * xmenu.c (cleanup_widget_value_tree): New function.
13736 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13737 calling free_menubar_widget_value_tree directly (Bug#9830).
13739 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13741 Fix some portability problems with 'inline'.

13743 (window_box_width, window_box_left, window_box_left_offset)
13744 (window_box_right, window_box_right_offset): Declare extern.
13745 Otherwise, these inline functions do not conform to C99 and
13746 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13747 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13748 * intervals.c (adjust_intervals_for_insertion)
13749 (adjust_intervals_for_deletion): Now extern, because otherwise the
13750 extern inline functions 'offset_intervals' couldn't refer to it.
13751 (static_offset_intervals): Remove.
13752 (offset_intervals): Rewrite using the old contents of
13753 static_offset_intervals. The old version didn't conform to C99
13754 because an extern inline function contained a reference to an
13755 identifier with static linkage.

13777 (Fwindow_vscroll): Doc fix.
13778 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13779 argument, since it makes no sense to pass a live window and for

13867 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
13868 label is not null (Bug#9951).

13890 (mouse_face_from_buffer_pos, note_mouse_highlight):
13891 Rename cover_string to disp_string.

13901 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
13902 past the beginning of the current glyph matrix.
13904 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
13906 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

13950 2011-10-29 Glenn Morris <rgm@gnu.org>
13952 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
13953 Not clear what it was for, and it causes various bugs. (Bug#9839)
13955 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13957 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
13958 possible random value that matches one of those tested as
13959 condition to clear the mouse face.
13961 2011-10-28 Chong Yidong <cyd@gnu.org>

13977 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13979 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13980 <oslsachem@gmail.com> for helping to debug this.
13982 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

13988 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13990 (w32font_open_internal, compute_metrics):
13991 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13992 instead of calling the "wide" APIs directly.
13994 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13996 * w32.h (syms_of_w32font): Add prototype.
13998 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

14001 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14002 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14003 (Fmove_to_window_line): Doc fix.
14005 2011-10-27 Chong Yidong <cyd@gnu.org>
14007 * process.c (make_process): Set gnutls_state to NULL.
14009 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14010 non-NULL, regardless of GNUTLS_INITSTAGE.
14011 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14012 an error. Set process slots as soon as we allocate them.
14014 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14016 2011-10-27 Chong Yidong <cyd@gnu.org>

14023 (deactivate_process): Call emacs_gnutls_deinit.
14025 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14027 * image.c (x_create_x_image_and_pixmap):
14028 * w32.c (sys_rename, w32_delayed_load):
14029 * w32font.c (fill_in_logfont):

14038 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14040 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14042 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14044 * keyboard.c (test_undefined): New function (bug#9751).
14045 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14047 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14049 * sysdep.c (init_sys_modes): Fix the check for the controlling
14050 terminal (Bug#6649).
14052 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14054 * dispextern.h (struct bidi_it): New member next_en_type.
14056 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14057 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14058 current character, check also for next_en_type being WEAK_EN.
14059 (bidi_resolve_weak): Don't enter the expensive loop if the current
14060 position is before next_en_pos. Record the bidi type of the first
14061 non-ET, non-BN character we find, in addition to its position.
14062 (bidi_level_of_next_char): Invalidate next_en_type when
14063 next_en_pos is over-stepped.
14065 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14067 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14068 * editfns.c: Rewrite current-time-zone so that it invokes
14069 the equivalent of (format-time-string "%Z") to get the time zone name.
14070 This fixes a bug when the time zone name contains characters that
14071 need converting from the system time locale to Emacs internal format.
14072 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14073 that patch fixed format-time-string to do the conversion, but
14074 I forgot to fix current-time-zone.
14075 (format_time_string): New function, containing most of
14076 what Fformat_time_string used to contain.
14077 (Fformat_time_string): Rewrite in terms of format_time_string.
14078 This doesn't change this function's behavior.
14079 (current-time-zone): Rewrite to use format_time_string.
14080 This fixes the bug reported by Michael Schierl in
14081 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14082 Jason Rumney's 2007-06-07 change worked around this bug, but
14084 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14086 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14088 * xdisp.c (start_display): If the character at POS is displayed
14089 via a display vector, reset IT->current.dpvec_index to zero.
14090 (try_window_reusing_current_matrix): If a line ends in a display
14091 vector or the next line starts in a display vector, continue
14092 redrawing the window even though the character position of
14093 start_row was reached.
14096 2011-10-18 Chong Yidong <cyd@gnu.org>
14098 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14099 with nobreak-char-display too.
14101 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14103 Fix part 3 of bug#9771.
14104 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14105 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14106 non-neutral characters if the current character is a paragraph
14107 separator (a.k.a. Newline). This avoids running the same
14108 expensive loop twice, once when we consume the preceding newline
14109 and the other time when the line actually needs to be displayed.
14110 Avoid the loop when we see neutrals on the base embedding level
14111 following a character whose directionality is the same as the
14112 paragraph's. This avoids running the expensive loop when a line
14113 ends in a long sequence of neutrals, like control characters.
14114 Add assertion against STRONG_AL type. Slightly rearrange code
14115 that determines the type of a neutral given the first non-neutral
14117 (bidi_level_of_next_char): Set next_en_pos to zero when
14118 invalidating its info.
14120 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14122 * xdisp.c (push_display_prop): Determine whether to record string
14123 or buffer position by IT->string, not by IT->method. Allow
14124 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14125 (move_it_vertically_backward): Don't look for character position
14126 immediately after the newline when in a continuation line.
14129 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14131 * window.c (coordinates_in_window): Rewrite and delabelize
14132 vertical border check. (Bug#5357) (Bug#9618)
14134 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14136 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14137 errors in XSetWindowBorder (bug#9310).
14139 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14141 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14142 avoid crash when xmalloc overrun checking is enabled.
14144 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14146 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14147 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14148 cursor motion with <left> and <right> arrow keys.
14150 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14151 some callers set that themselves.
14153 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14155 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14156 display string and the previous row comes from the same string and
14157 is empty. (Bug#9739) (Bug#9738)
14159 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14161 * doc.c (get_doc_string): Encode file name (bug#9735).
14163 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14165 * bidi.c (bidi_level_of_next_char):
14166 * xdisp.c (get_visually_first_element): Remove old incorrect
14167 comments regarding the Unicode Line Separator character.
14169 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14171 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14173 * alloc.c (Fgc_status): Do not access beyond zombies array
14174 boundary if nzombies > MAX_ZOMBIES.
14175 * alloc.c (dump_zombies): Add missing format specifier.
14177 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14179 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14180 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14182 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14183 Some packages use them to denote characters with modifiers.
14185 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14187 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14188 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14189 matching a pp-number. Rename parameter var to var1.
14191 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14193 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14195 2011-10-08 Glenn Morris <rgm@gnu.org>
14197 * callint.c (Fcall_interactively): Give a more explicit error for the
14198 'c' case with a non-character input. (Bug#8479)
14200 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14202 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14204 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14205 lines that are hscrolled on the left.
14207 * dispnew.c (buffer_posn_from_coords): Account for a possible
14208 presence of header-line. (Bug#4426)
14210 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14212 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14213 Don't advertise functionality which we discourage or doesn't work.
14215 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14217 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14218 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14219 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14220 this makes Emacs dump core during garbage collection on rare
14221 occasions. sizeof is obviously inferior to offsetof here, so
14222 stick with offsetof.
14223 (GC_POINTER_ALIGNMENT): New macro.
14224 (mark_memory): Omit 3rd (offset) arg; caller changed.
14225 Don't assume EMACS_INT alignment is the same as pointer alignment.
14227 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14229 * keyboard.c (read_key_sequence_remapped): New var.
14230 (read_key_sequence): Compute remapping in the right buffer.
14231 (command_loop_1): Use read_key_sequence's remapping directly.
14233 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14235 * dired.c (file_name_completion): Don't expand file name.
14236 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14237 before checking file name handler.
14239 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14240 they've been requested explicitly (bug#9591).
14242 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14244 * keymap.c (Fsingle_key_description): Use make_specified_string
14245 instead of build_string to build string from push_key_description.
14248 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14250 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14251 This fixes a Y2038 bug on 64-bit hosts.
14252 * buffer.c (reset_buffer):
14253 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14254 (Fclear_buffer_auto_save_failure):
14255 Use 0, not -1, to represent an unset failure time, since time_t
14256 might not be signed.
14258 Remove dependency on glibc malloc internals.
14259 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14260 Move back here from lisp.h, but with their new implementations.
14261 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14262 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14263 * charset.c (charset_table_init): New static var.
14264 (syms_of_charset): Use it instead of xmalloc. This removes a
14265 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14266 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14267 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14268 Move back to alloc.c.
14269 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14270 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14272 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14274 * nsterm.m (windowDidResize): Call x_set_window_size only when
14275 ns_in_resize is true. Otherwise set pixelwidth/height and
14276 call change_frame_size (Bug#9628).
14278 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14280 Port --enable-checking=all to Fedora 14 x86-64.
14281 * charset.c (syms_of_charset): Also account for glibc malloc's
14282 internal overhead when calculating the initial malloc maximum.
14284 Port --enable-checking=all to Fedora 14 x86.
14285 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14287 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14288 (overrun_check_realloc, overrun_check_free):
14289 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14290 That way, xmalloc returns a properly-aligned pointer even if
14291 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14292 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14293 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14294 into account when calculating the initial malloc maximum.
14295 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14296 Move here from alloc.c, so that charset.c can use it too.
14297 Properly align; the old code wasn't right for common 32-bit hosts
14298 when configured with --enable-checking=all.
14299 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14300 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14302 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14304 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14307 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14309 * xdisp.c (compute_display_string_end): If there's no display
14310 string at CHARPOS, return -1.
14312 * bidi.c (bidi_fetch_char): When compute_display_string_end
14313 returns a negative value, treat the character as a normal
14314 character not covered by a display string. (Bug#9624)
14316 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14318 * lread.c (Fread_from_string): Fix typo in docstring.
14320 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14322 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14323 newline, reseat the iterator instead of bidi-iterating there one
14324 character at a time. (Bug#9610)
14325 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14326 TO_CHARPOS if the bidi iterator is at base embedding level.
14328 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14330 * lread.c (readevalloop): Use correct code for NBSP.
14331 (read1): Likewise. (Bug#9608)
14333 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14335 * dbusbind.c (Fdbus_register_signal): When service is not
14336 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14338 2011-09-25 Glenn Morris <rgm@gnu.org>
14340 * buffer.c (truncate-lines): Doc fix.
14342 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14344 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14345 (Fset_window_next_buffers): Doc fix.
14347 2011-09-24 Glenn Morris <rgm@gnu.org>
14349 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14351 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14353 Fix minor problems found by static checking.
14354 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14355 * indent.c (Fvertical_motion): Fix == vs = typo.
14357 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14359 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14360 Default value is now t. Doc fix.
14362 * indent.c (Fvertical_motion): Compute and apply the overshoot
14363 logic when moving up, not only when moving down. Fix the
14364 confusing name and values of the it_overshoot_expected variable;
14365 logic changes accordingly. (Bug#9254) (Bug#9549)
14367 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14368 CHARPOS is covered by a display string which includes newlines.
14369 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14370 is covered by a display string with embedded newlines.
14372 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14374 * dbusbind.c (Fdbus_register_signal): Add match rule to
14375 Vdbus_registered_objects_table. (Bug#9581)
14376 (Fdbus_register_method, Vdbus_registered_objects_table):
14379 2011-09-24 Jim Meyering <meyering@redhat.com>
14381 do not ignore write error for any output size
14382 The previous change was incomplete.
14383 While it makes emacs --batch detect the vast majority of stdout
14384 write failures, errors were still ignored whenever the output size is
14385 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14386 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14387 && echo FAIL: ignored write error
14388 FAIL: ignored write error
14389 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14390 && echo FAIL: ignored write error
14391 FAIL: ignored write error
14392 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14394 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14396 * emacs.c (Fkill_emacs): In noninteractive mode exit
14397 non-successfully if a write error occurred on stdout. (Bug#9574)
14399 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14401 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14404 * dispextern.h (struct it): Update the comment documenting what
14407 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14409 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14410 a display string, extend search for cursor position to end of row.
14411 (find_row_edges): If the row ends in a newline from a display
14412 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14413 Handle the case of a display string with multiple newlines.
14414 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14415 non-empty line. Fixes confusing cursor motion with arrow keys at
14416 the beginning of a line that starts with whitespace.
14418 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14420 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14423 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14425 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14426 boolean (Bug#9154).
14428 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14430 * xdisp.c (display_line): Record maximum and minimum buffer
14431 positions even if no glyphs were produced (e.g., by a zero-width
14432 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14433 buffer positions that will be removed from the glyph row because
14435 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14436 column is beyond frame width: don't subtract 1 "pixel" when
14437 computing width of the stretch.
14438 (reseat_at_next_visible_line_start): Undo the change made on
14439 2011-09-17 that saved paragraph information and restored it after
14440 the call to `reseat'. (Bug#9545)
14442 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14444 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14445 and turn window cursor on if cleared (Bug#9415).
14447 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14449 * search.c (boyer_moore): Take unibyte characters from pattern
14450 literally. (Bug#9458)
14452 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14454 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14456 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14458 Fix minor problem found by static checking.
14459 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14460 initialized, to pacify gcc -Wuninitialized.
14462 * fileio.c: Report proper errno when syscall falls.
14463 (Finsert_file_contents): Save and restore errno,
14464 so that report_file_error outputs the correct diagnostic.
14465 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14467 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14469 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14471 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14473 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14474 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14476 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14478 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14479 about the current paragraph and restore it after the call to reseat.
14481 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14482 (bidi_find_paragraph_start): Search back for paragraph beginning
14483 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14484 (bidi_move_to_visually_next): Only trigger paragraph-related
14485 computations when the last character is a newline or at EOB, not
14486 just any NEUTRAL_B. (Bug#9470)
14488 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14489 truncated lines if point is covered by a display string. (Bug#9524)
14491 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14493 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14494 (cons_to_x_long): New function.
14495 (lisp_data_to_selection_data): Use it. Correct the test for
14496 short-versus-long data; it was negated. Break out of vector
14497 loop, for efficiency, when a long datum is discovered.
14499 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14501 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14503 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14505 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14506 GCC PR/17406) by declaring this function with external scope.
14508 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14510 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14511 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14513 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14515 * editfns.c (Fformat): Correctly handle text properties on "%%".

14521 * term.c (encode_terminal_code):
14522 * composite.c (composition_update_it, get_composition_id):
14523 * xdisp.c (get_next_display_element)
14524 (fill_composite_glyph_string): Add comments about special meaning
14525 of TAB characters in a composition.
14527 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14529 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14530 This occurs when processing a multibyte format.
14531 Problem reported by Wolfgang Jenker.
14533 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14535 * xdisp.c (try_cursor_movement): Only check for exact match if
14536 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14538 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14540 Remove unused external symbols.
14541 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14542 * xdisp.c (calc_pixel_width_or_height): Now static.
14543 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14544 * indent.c (check_display_width):
14545 * w32term.c: Fix comment to match code.
14546 * xterm.c, xterm.h (x_catching_errors): Remove.
14548 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14550 * xselect.c: Use signed conversions more consistently (Bug#9498).
14551 (selection_data_to_lisp_data): Assume incoming selection data are
14552 signed integers, not unsigned. This is to be consistent with
14553 outgoing selection data, which was modified to use signed integers
14554 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14555 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14556 expects long, not unsigned long.
14558 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14560 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14561 computation of loop end. Reported by Johan Bockgård
14564 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14566 * frame.c (Fother_visible_frames_p): Function deleted.
14568 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14570 * indent.c (compute_motion): Process display vector front to back
14571 rather than the other way around. (Bug#2496)
14573 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14575 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14577 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14579 * minibuf.c (Fread_from_minibuffer): Doc fix.
14581 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14583 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14584 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14586 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14588 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14589 value for non-existent files.
14591 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14593 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14594 set its "size" to -1. This will set the modtime_size field of
14595 the corresponding buffer to -1, which is what
14596 verify-visited-file-modtime expects for files that do not exist.
14599 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14601 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14603 * lisp.h: ... from here. push_key_description is no longer
14604 defined in keyboard.c, so its declaration should not be in
14605 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14606 logically belongs with push_key_description.
14608 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14610 * buffer.h: Include <sys/types.h> instead of <time.h>.
14611 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14612 Problem reported by Herbert J. Skuhra.
14614 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14616 * xml.c (parse_region): Make the parsing work for
14617 non-comment-starting XML files again (bug#9144).
14619 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14621 * image.c (gif_load): Fix calculation of bottom and right corner.
14624 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14626 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14627 redisplay in small windows.
14629 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14631 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14633 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14635 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14636 Operate on live windows only.
14638 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14640 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14642 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14644 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14645 only under bidi iteration.
14647 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14649 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14651 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14653 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14654 Without this fix, the command to link temacs failed due to an
14655 undefined symbol __builtin_isnan. This is because
14656 /usr/include/iso/math_c99.h #defines isnan(x) to
14657 __builtin_isnan(x), but the bundled gcc, which identifies itself
14658 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14660 * floatfns.c (isnan): #undef, and then #define to a clone of
14662 (Fisnan): Always define, since it's always available now.
14663 (syms_of_floatfns): Always define isnan at the Lisp level.
14665 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14667 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14669 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14671 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14672 The previous code assumed that file offsets (off_t values) fit in
14673 EMACS_INT variables, which is not true on typical 32-bit hosts.
14674 The code messed up by falsely reporting buffer overflow in cases
14675 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14676 when "big" contains more than 2**29 bytes, even though this
14677 inserts just one byte and does not overflow the buffer.
14678 (Finsert_file_contents): Store file offsets as off_t
14679 values, not as EMACS_INT values. Check for overflow when
14680 converting between EMACS_INT and off_t. When checking for
14681 buffer overflow or for overlap, take the offsets into account.
14682 Don't use EMACS_INT for small values where int suffices.
14683 When checking for overlap, fix a typo: ZV was used where
14684 ZV_BYTE was intended.
14685 (Fwrite_region): Don't assume off_t fits into 'long'.
14686 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14688 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14690 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14692 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14694 sprintf-related integer and memory overflow issues (Bug#9412).
14696 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14697 (esprintf, exprintf, evxprintf): New functions.
14698 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14699 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14700 (modify_event_symbol): Do not assume that the length of
14701 name_alist_or_stem is safe to alloca and fits in int.
14702 (Fexecute_extended_command): Likewise for function name and binding.
14703 (Frecursion_depth): Wrap around reliably on integer overflow.
14704 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14705 since some callers pass EMACS_INT values.
14706 (Fsingle_key_description): Don't crash if symbol name contains more
14707 than MAX_ALLOCA bytes.
14708 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14709 (get_minibuffer): Arg is now EMACS_INT, not int.
14710 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14711 (esprintf, exprintf, evxprintf): New decls.
14712 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14714 * dbusbind.c (signature_cat): New function.
14715 (xd_signature, Fdbus_register_signal):
14716 Do not overrun buffer; instead, report string overflow.
14718 * dispnew.c (add_window_display_history): Don't overrun buffer.
14719 Truncate instead; this is OK since it's just a log.
14721 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14722 even if the time zone offset is outlandishly large.
14723 Don't mishandle offset == INT_MIN.
14725 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14726 when creating daemon; the previous buffer-overflow check was incorrect.
14728 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14729 which has the guts of the old verror function.
14731 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14732 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14734 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14735 (font_unparse_xlfd): Don't blindly alloca long strings.
14736 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14737 fits in int, when using sprintf. Use single snprintf to count
14738 length of string rather than counting it via multiple sprintfs;
14739 that's simpler and more reliable.
14740 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14741 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14742 sprintf, in case result does not fit in int.
14744 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14745 (fontset_from_font): Print it.
14747 * frame.c (tty_frame_count): Now printmax_t, not int.
14748 (make_terminal_frame, set_term_frame_name): Print it.
14749 (x_report_frame_params): In X, window IDs are unsigned long,
14750 not signed long, so print them as unsigned.
14751 (validate_x_resource_name): Check for implausibly long names,
14752 and don't assume name length fits in 'int'.
14753 (x_get_resource_string): Don't blindly alloca invocation name;
14754 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14757 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14758 (xg_check_special_colors, xg_set_geometry):
14759 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14761 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14762 Use esprintf, not sprintf, in case result does not fit in int.
14764 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14765 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14766 it as a large positive number.
14767 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14768 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14770 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14771 in case result does not fit in int.
14773 * print.c (float_to_string): Detect width overflow more reliably.
14774 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14775 buffer overrun. Don't assume list length fits in 'int'. Treat
14776 print length of 0 as 0, not as infinity; to be consistent with other
14777 uses of print length in this function. Don't overflow print length
14778 index. Don't assume hash table size fits in 'long', or that
14779 vectorlike size fits in 'unsigned long'.
14781 * process.c (make_process): Use printmax_t, not int, to format
14782 process-name gensyms.
14784 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14786 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14787 to avoid potential buffer overrun.
14789 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14790 if X resource line is longer than 512 bytes.
14792 * xfns.c (x_window): Make sprintf buffer a bit bigger
14793 to avoid potential buffer overrun.
14795 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14797 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14799 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14801 Integer overflow fixes for scrolling, etc.
14802 Without these, Emacs silently mishandles large integers sometimes.
14803 For example, "C-u 4294967297 M-x recenter" was treated as if
14804 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14806 * xdisp.c (try_window_id): Check Emacs fixnum range before
14807 converting to 'int'.
14809 * window.c (window_scroll_line_based, Frecenter):
14810 Check that an Emacs fixnum is in range before assigning it to 'int'.
14811 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14812 values converted from Emacs fixnums.
14813 (Frecenter): Don't wrap around a line count if it is out of 'int'
14814 range; instead, treat it as an extreme value.
14815 (Fset_window_configuration, compare_window_configurations):
14816 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14818 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14819 that can exceed INT_MAX. Check that EMACS_INT value is in range
14820 before assigning it to the (possibly-narrower) index.
14821 (match_limit): Don't assume that a fixnum can fit in 'int'.
14823 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14826 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14827 (Fvertical_motion): Don't wrap around LINES values that don't fit
14828 in 'int'. Instead, treat them as extreme values. This is good
14829 enough for windows, which can't have more than INT_MAX lines anyway.
14831 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14833 * Require libxml/parser.h to avoid compilation warning.
14835 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14837 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14838 since this reportedly can destroy thread storage.
14840 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14842 * syntax.c (find_defun_start): Update all cache variables if
14843 exiting early (Bug#9401).
14845 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14847 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14849 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14850 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14851 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14853 * term.c (tty_append_glyph): New function.
14854 (produce_stretch_glyph): Static function and its prototype deleted.
14856 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14859 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14861 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14862 when checking :margin (Bug#9390).
14863 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14864 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14865 so that the name doesn't mislead. All uses changed.
14867 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14869 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14872 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14874 * xdisp.c (move_it_to): Don't bail out early when reaching
14875 position beyond to_charpos, if we are scanning backwards.
14876 (move_it_vertically_backward): When DY == 0, make sure we get to
14877 the first character in the line after the newline.
14879 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14881 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14882 (ccl_driver): Do not generate an out-of-range pointer.
14883 (Fccl_execute_on_string): Remove unnecessary check for
14884 integer overflow, noted by Stefan Monnier in
14885 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14886 Remove a FIXME that didn't need fixing.
14887 Simplify the newly-introduced buffer reallocation code.
14889 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14891 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14893 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14895 Integer and memory overflow issues (Bug#9196).
14897 * doc.c (get_doc_string): Rework so that
14898 get_doc_string_buffer_size is the actual buffer size, rather than
14899 being 1 less than the actual buffer size; this makes xpalloc more
14902 * image.c (x_allocate_bitmap_record, cache_image):
14903 * xselect.c (Fx_register_dnd_atom):
14904 Simplify previous changes by using xpalloc.
14906 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14907 since either will do and ptrdiff_t is convenient with xpalloc.
14909 * charset.c (charset_table_size)
14910 (struct charset_sort_data.priority): Now ptrdiff_t.
14911 (charset_compare): Don't overflow if priorities differ greatly.
14912 (Fsort_charsets): Don't assume list length fits in int.
14913 Check for size-calculation overflow when allocating sort data.
14914 (syms_of_charset): Allocate an initial charset table that is
14915 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14917 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14919 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14920 The actual value is always <= INT_MAX, and leaving it unsigned made
14921 overflow checking harder.
14923 * dispextern.h (struct glyph_matrix.rows_allocated)
14924 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14925 with xpalloc. The values are still always <= INT_MAX.
14927 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14929 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14930 (SAFE_NALLOCA): New macro.
14932 * region-cache.c (struct boundary.pos, find_cache_boundary)
14933 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14934 (set_cache_region, invalidate_region_cache)
14935 (revalidate_region_cache, know_region_cache, region_cache_forward)
14936 (region_cache_backward, pp_cache):
14937 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14938 so that ptrdiff_t * can be passed to xpalloc.
14939 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14940 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14941 (pp_cache): Don't assume cache_len fits in int.
14942 * region-cache.h: Adjust extern decls to match.
14944 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14945 EMACS_INT, since either will do, for xpalloc.
14947 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14948 (xnmalloc, xnrealloc, xpalloc): New functions.
14950 * bidi.c (bidi_shelve_header_size): New constant.
14951 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14952 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14954 * bidi.c (bidi_cache_shrink):
14955 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14957 Don't update size of array until after memory allocation succeeds,
14958 because xmalloc/xrealloc may not return.
14959 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14960 now that we have proper integer overflow checking.
14961 (record_overlay_string, overlay_strings): Catch overflows when
14962 calculating size of overlay_str_buf.
14964 * callproc.c (Fcall_process): Check for size overflow when
14965 calculating size of args2.
14966 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14967 Normally we prefer signed values, but sticking with ptrdiff_t would
14968 require adding more-complicated checks.
14970 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14971 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14972 Redo buffer-overflow calculations to avoid integer overflow.
14973 Add a FIXME comment where memory seems to be over-allocated.
14975 * character.c (Fstring): Check for size-calculation overflow.
14977 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14978 unnecessary integer overflow. Check for size overflow.
14979 (encode_coding_object): Don't update size until xmalloc succeeds.
14981 * composite.c (get_composition_id): Check for overflow in glyph
14982 length calculations.
14984 Integer and memory overflow fixes for display code.
14985 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14986 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14987 (scrolling_window): Check for overflow in size calculations.

14995 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14996 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14999 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15000 (get_doc_string): Check for size calculation overflow.
15001 Don't update size until allocation succeeds.
15002 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15003 EMACS_INT, where ptrdiff_t will do.
15004 (Fsubstitute_command_keys): Check for string overflow.
15006 * editfns.c (set_time_zone_rule): Don't assume environment length
15008 (message_length): Now ptrdiff_t, not int.
15009 (Fmessage_box): Don't update size until allocation succeeds.
15010 Don't assume message length fits in int.
15011 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15013 * emacs.c (main): Do not reallocate argv, since there is a null at
15014 the end that can be overwritten, and this way there's no need to
15015 worry about size-calculation overflow.
15016 (sort_args): Check for size-calculation overflow.
15018 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15020 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15022 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15023 (x_set_scroll_bar_width, x_figure_window_size):
15024 Check for integer overflow.
15025 (x_set_alpha): Do not assume XINT fits in int.
15027 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15028 This is for the members text_lines, text_cols, total_lines, total_cols,
15029 where the system imposes an 'int' limit.
15031 * fringe.c (Fdefine_fringe_bitmap):
15032 Don't update size until alloc works.
15034 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15035 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15037 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15038 Check for size-calculation overflow.
15039 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15040 do, as we prefer signed integers.
15041 (id_to_widget.max_size, id_to_widget.used)
15042 (xg_store_widget_in_map, xg_remove_widget_from_map)
15043 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15044 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15045 Use and return ptrdiff_t, not int.
15046 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15047 * gtkutil.h: Change prototypes to match the above.
15049 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15050 are duplicate now that they've been promoted to lisp.h.
15051 (x_allocate_bitmap_record, x_alloc_image_color)
15052 (make_image_cache, cache_image, xpm_load):
15053 Don't update size until alloc is done.
15054 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

15063 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15064 Use ptrdiff_t, not int, to count maps.
15065 (read_char_minibuf_menu_prompt): Check for overflow in size
15066 calculations. Don't update size until allocation succeeds.
15067 Redo calculations to avoid overflow.
15068 * keyboard.h: Change prototypes to match the above.
15070 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15072 (current_minor_maps): Check for size calculation overflow.
15073 * keymap.h: Change prototypes to match the above.
15075 * lread.c (read1, init_obarray): Don't update size until alloc done.
15077 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15096 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15097 for command line length. Do not attempt to address one before the
15098 beginning of an array, as that's not portable.
15100 * term.c (max_frame_lines): Remove; unused.
15101 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15103 (encode_terminal_code, calculate_costs): Check for size
15104 calculation overflow.

15126 Use ptrdiff_t, not int, for sizes.
15127 (Finternal_make_lisp_face, cache_face):
15128 Check for size calculation overflow.
15129 (cache_face): Treat size calculation overflows as if they were
15130 memory exhaustion (the usual treatment), rather than aborting.
15132 * xfns.c (x_encode_text, x_set_name_internal)
15133 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15134 sizes, since they can exceed INT_MAX in size. Check for size
15135 calculation overflow.
15137 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15138 (xg_select): Check for size calculation overflow.
15139 Don't update size until alloc done.
15141 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15142 as sprintf is limited to int lengths.
15144 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15145 (X_LONG_MIN): New macros.
15146 Use them to make the following changes clearer.
15147 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15148 This change doesn't affect the value now, but it may help remind
15149 future maintainers not to raise the value too much later.
15150 (SELECTION_QUANTUM): Remove, replacing with ...
15151 (selection_quantum): ... new function, which avoids overflow.
15153 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15154 assumption that selection length fits in 'int'.

15158 (lisp_data_to_selection_data, clean_local_selection_data):
15159 Use ptrdiff_t, not int, to record length of selection.
15160 (x_reply_selection_request, x_get_window_property)
15161 (receive_incremental_selection, x_property_data_to_lisp):
15162 Redo calculations to avoid overflow.
15163 (x_reply_selection_request): When sending hint, ceiling it at
15164 X_LONG_MAX rather than relying on wraparound overflow to send
15166 (x_get_window_property, receive_incremental_selection)
15167 (lisp_data_to_selection_data, x_property_data_to_lisp):
15168 Check for size-calculation overflow.
15169 (x_get_window_property, receive_incremental_selection)

15171 Don't store size until memory allocation succeeds.
15172 (x_get_window_property): Plug memory leak on memory exhaustion.
15173 Don't double-block input; malloc is safe here. Don't assume 2**34
15174 - 4 fits in unsigned long. Add an xassert to check
15175 XGetWindowProperty overflow. Be more careful about overflow
15176 calculations, and distinguish size from memory overflow better.
15177 (receive_incremental_selection): When tracing, don't assume
15178 unsigned int is less than INT_MAX.
15179 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15180 harmful) conversions of unsigned short to int.
15181 (lisp_data_to_selection_data): Don't assume that integers
15182 in the range -65535 through -1 fit in an X unsigned short.
15183 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15184 result parameters unless successful. Rely on cons_to_unsigned
15185 to report problems with elements; the old code wasn't right anyway.
15186 (x_check_property_data): Check for int overflow; we cannot use
15187 a wider type due to X limits.
15188 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15190 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15192 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15193 (x_term_init): Check for size calculation overflow.
15194 (x_color_cells): Don't store size until memory allocation succeeds.
15195 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
15196 Don't assume alloca size is less than MAX_ALLOCA.
15197 (x_term_init): Don't assume length fits in int (sprintf is limited
15200 Use ptrdiff_t for composition IDs.

15219 * image.c (xpm_get_color_table_h):
15220 * lisp.h (hash_lookup, hash_put):
15221 * minibuf.c (Ftest_completion):
15222 Use ptrdiff_t for hash table indexes, not int (which is too
15223 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15224 32-bit --with-wide-int hosts).
15226 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15227 Add a FIXME comment about memory leaks.
15228 (syms_of_charset): Don't assume xmalloc returns.

15232 * character.h (CHAR_WIDTH):
15233 * indent.c (MULTIBYTE_BYTES_WIDTH):
15234 Use sanitize_char_width to avoid undefined and/or bad behavior
15235 with outlandish widths.
15236 * character.h (sanitize_tab_width): Rename from sanitize_width,
15237 now that we have two such functions. All uses changed.
15238 (sanitize_char_width): New inline function.
15240 Don't assume that tab-width fits in int.
15241 * character.h (sanitize_width): New inline function.
15242 (SANE_TAB_WIDTH): New macro.
15243 (ASCII_CHAR_WIDTH): Use it.
15244 * indent.c (sane_tab_width): Remove. All uses replaced by

15248 * fileio.c: Integer overflow issues with file modes.
15249 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15251 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15252 Remove unreachable code.
15253 (read_hex, load_charset_map_from_file): Check for integer overflow.
15255 * xterm.c: Don't go over XClientMessageEvent limit.
15256 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15257 (x_send_scroll_bar_event): Likewise. Check that the size does not
15258 exceed limits imposed by XClientMessageEvent, as well as the usual
15259 ptrdiff_t and size_t limits.
15261 * keyboard.c: Overflow, signedness and related fixes.
15262 (make_lispy_movement): Use same integer type in forward decl
15263 that is used in the definition.
15264 (read_key_sequence, keyremap_step):
15265 Change bufsize argument back to int, undoing my 2011-03-30 change.
15266 We prefer signed types, and int is wide enough here.
15267 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15268 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15269 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15270 length, not size_t. Use ptrdiff_t for index, not int.
15271 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15272 possibility of integer overflow.
15274 Overflow, signedness and related fixes for images.
15276 * dispextern.h (struct it.stack[0].u.image.image_id)

15295 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15296 (lookup_image): Remove unnecessary tests.
15297 (xbm_image_p): Locals are now of int, not EMACS_INT,
15298 since parse_image_check makes sure they fit into int.
15299 (png_load, gif_load, svg_load_image):
15300 Prefer int to unsigned where either will do.
15301 (tiff_handler): New function, combining the cores of the
15302 old tiff_error_handler and tiff_warning_handler.
15303 This function is rewritten to use vsnprintf and thereby avoid
15304 stack buffer overflows. It uses only the features of vsnprintf
15305 that are common to both POSIX and native Microsoft.
15306 (tiff_error_handler, tiff_warning_handler): Use it.
15307 (tiff_load, gif_load, imagemagick_load_image):
15308 Don't assume :index value fits in 'int'.
15309 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15310 (imagemagick_load_image): Check that crop parameters fit into
15311 the integer types that MagickCropImage accepts. Don't assume
15312 Vimagemagick_render_type has a nonnegative value. Don't assume
15313 size_t fits in 'long'.
15314 (gs_load): Use printmax_t to print the widest integers possible.
15315 Check for integer overflow when computing image height and width.
15317 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15319 * xdisp.c (redisplay_window): Don't force window start if point
15320 will be invisible in the resulting window. (Bug#9324)

15324 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15325 the display spec is of the form `(space ...)'.
15326 (handle_display_spec): Return the value returned by
15327 handle_single_display_spec, not just 1 or zero.
15328 (handle_single_display_spec): If the display spec is of the form
15329 `(space ...)', and specifies display in the text area, return 2
15331 (try_cursor_movement): Check for the need to scroll more
15332 accurately, and prefer exact match for point under bidi.
15333 Don't advance `row' beyond the last row of the window.
15335 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15336 into disp_prop; all users changed.
15338 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15339 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15340 for the text covered by the display property.

15350 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15351 buffers, return left-to-right.
15352 (set_cursor_from_row): Consider candidate row a win if its glyph
15353 represents a newline and point is on that newline. Fixes cursor
15354 positioning on the newline at EOL of R2L text within L2R
15355 paragraph, and vice versa.
15356 (try_cursor_movement): Check continued rows, in addition to
15357 continuation rows. Fixes unwarranted scroll when point enters a
15358 continued line of R2L text within an L2R paragraph, or vice versa.
15359 (cursor_row_p): Consider the case of point being equal to
15360 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15361 from the end of a short line to the beginning of a continued line
15362 of R2L text within L2R paragraph.
15363 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15364 composed characters.

15379 2011-08-22 Kenichi Handa <handa@m17n.org>
15381 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15382 extra slot even if the purpose is char-code-property-table.
15384 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15386 * xdisp.c (redisplay_window): When computing centering_position,
15387 account for the height of the header line. (Bug#8874)
15389 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15390 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15391 candidate is selected by the mouse, and that candidate has a
15392 composed character under the mouse.
15394 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15395 coordinates reported by pos-visible-in-window-p for a composed
15396 character in column zero.
15398 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15400 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15402 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15404 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15405 consider it a hit if to_charpos is anywhere in the range of the
15406 composed buffer positions.
15408 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15410 * image.c (gif_load): Don't assume that each subimage has the same
15411 dimensions as the base image. Handle disposal method that is
15412 "undefined" by the gif spec (Bug#9335).
15414 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15416 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15417 (Fcondition_case): Document `debug' symbol in error handler.
15419 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15421 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15422 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15423 from an Org mode buffer to a Speedbar frame.
15425 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15426 a composition, take its buffer position from IT->cmp_it.charpos.
15427 Fixes cursor positioning at the beginning of a line that begins
15428 with a composed character.
15430 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15432 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15433 character bidirectional type, use STRONG_L instead. Fixes crashes
15434 in a buffer produced by `describe-categories'.
15436 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15437 members before the level stack, so they would be saved and
15438 restored when copying iterator state. Fixes incorrect reordering
15439 around TABs covered by display properties.
15441 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15443 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15447 * eval.c (internal_condition_case, internal_condition_case_1)
15448 (internal_condition_case_2, internal_condition_case_n):
15449 Remove unnecessary aborts (Bug#9081).
15451 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15453 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15454 has no `load' handler, try opening the file locally. (Bug#9311)
15456 2011-08-16 Ken Brown <kbrown@cornell.edu>
15458 * gmalloc.c: Expand comment.

15462 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15463 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15465 2011-08-16 Ken Brown <kbrown@cornell.edu>
15467 Fix memory allocation problems in Cygwin build (Bug#9273).
15469 * unexcw.c ( __malloc_initialized): Declare external variable.
15470 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15472 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15474 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

15502 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
15503 coordinates of the iterator when restoring from ppos_it.
15506 2011-08-14 Kenichi Handa <handa@m17n.org>
15508 * process.c (create_process): Call setup_process_coding_systems
15509 after the pid of the process is set to -1 (Bug#8162).
15511 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15513 * xdisp.c (move_it_in_display_line_to): Don't invoke
15514 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15515 ppos_it. Fixes vertical cursor motion when line beginning is
15516 covered by an image. (Bug#9296)
15518 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15520 * nsterm.h (ns_run_ascript): Declare.

15523 * nsfns.m (as_script, as_result, as_status): New static variables.
15524 (ns_run_ascript): New function.
15525 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15526 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15527 the event loop. Get status from as_status (Bug#7276).
15529 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15530 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15531 the event loop (Bug#7276).
15533 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15535 * gnutls.c (QCgnutls_bootprop_priority)

15556 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15557 (Fnetwork_interface_list): Allocate in increments of bytes instead
15558 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15559 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15561 (struct ifflag_def): notrailers is smart on OSX.
15562 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15563 Get hardware address with getifaddrs if available.
15565 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15567 * xdisp.c (iterate_out_of_display_property): xassert that
15568 IT->position is set to within IT->object's boundaries. Break from
15569 the loop as soon as EOB is reached; avoids infloops in redisplay
15570 when IT->position is set up wrongly due to some bug.
15571 Set IT->current to match the bidi iterator unconditionally.
15572 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15573 entry. Force push_it to save on the stack the current
15574 buffer/string position, to be restored by pop_it. Fix flags in
15575 the iterator structure wrt the object coming from a display
15576 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15577 properties. (Bug#9284)
15579 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15581 * fontset.c (fontset_get_font_group): Add proper type checks.

15591 2011-08-08 Eli Zaretskii <eliz@gnu.org>
15593 * xdisp.c (forward_to_next_line_start): Allow to use the
15594 no-display-properties-and-no-overlays under bidi display.
15595 Set disp_pos in the bidi iterator to avoid searches for display
15596 properties and overlays.
15598 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15600 * editfns.c (Fset_time_zone_rule): Document relationship with the
15603 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
15604 the font entity extracted from the cache (Bug#8109).
15606 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15608 * composite.c (autocmp_chars): Don't reset point. That is done by
15609 restore_point_unwind (Bug#5984).
15611 2011-08-07 Juri Linkov <juri@jurta.org>
15613 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15614 to show the arg `TIME' instead of `TIMEVAL'.
15616 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15618 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15619 display property strides EOL and includes a newline, as in
15620 longlines-mode. (Bug#9254)
15621 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15622 word-wrap under bidirectional display. (Bug#9224)
15624 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15625 is non-zero, even if the data buffer is NULL. Fixes a crash in
15626 vertical-motion with longlines-mode. (Bug#9254)
15628 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15630 * bidi.c <bidi_cache_total_alloc>: Now static.
15631 (bidi_initialize): Initialize bidi_cache_total_alloc.
15633 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15636 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15637 amount allocated this far in `bidi_cache_total_alloc'.
15638 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15639 non-zero, only free the data buffer without restoring the cache
15640 contents. All callers changed.
15642 * dispextern.h (bidi_unshelve_cache): Update prototype.
15644 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15645 (move_it_in_display_line, move_it_to)
15646 (move_it_vertically_backward, move_it_by_lines): Replace the call
15647 to xfree to an equivalent call to bidi_unshelve_cache.
15648 (move_it_in_display_line_to): Fix logic of returning
15649 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15651 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15653 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15654 came from a string character with a `cursor' property. (Bug#9229)
15656 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15658 * Makefile.in (LIB_PTHREAD): New variable.
15659 (LIBES): Add LIB_PTHREAD (Bug#9216).
15661 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15662 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15664 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15666 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15668 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15670 * xterm.c (x_find_topmost_parent): New function.
15671 (x_set_frame_alpha): Find topmost parent window with
15672 x_find_topmost_parent and set the property there also (bug#9181).
15673 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15675 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15677 * callproc.c (Fcall_process): Avoid vfork clobbering
15678 the local vars buffer, coding_systems, current_dir.
15680 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15682 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15684 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15686 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15687 so that it is not optimized away.
15689 * xdisp.c (compute_display_string_pos): Remove unused local.
15691 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15693 Fix slow cursor motion and scrolling in large buffers with
15694 selective display, like Org Mode buffers. (Bug#9218)
15696 * dispextern.h (struct bidi_it): New member disp_prop_p.
15698 * xdisp.c: Remove one-slot cache of display string positions.
15699 (compute_display_string_pos): Accept an additional argument
15700 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15701 for a display string or property. If found, set DISP_PROP_P
15704 * bidi.c (bidi_fetch_char): Accept an additional argument
15705 DISP_PROP_P, and pass it to compute_display_string_pos.
15706 Only handle text covered by a display string if DISP_PROP_P is returned
15707 non-zero. All callers of bidi_fetch_char changed.
15709 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15711 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15713 2010-12-03 Don March <don@ohspite.net>
15715 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15716 last character M-[char] is translated to ESC [char] (bug#7541).
15718 2011-08-02 Kenichi Handa <handa@m17n.org>
15720 * lisp.h (uniprop_table): Extern it.
15722 * chartab.c (uniprop_table): Make it non-static.
15724 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15726 * xdisp.c (forward_to_next_line_start): Accept additional argument
15727 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15729 (reseat_at_next_visible_line_start): Use the bidi iterator state
15730 returned by forward_to_next_line_start to restore the state of
15731 it->bidi_it after backing up to previous newline. (Bug#9212)
15733 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15735 * regex.c (re_comp): Protoize.
15736 (re_exec): Fix return type.
15737 (regexec): Fix type of `ret'. (Bug#9203)
15739 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15741 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15742 This is needed if max-image-size is a floating-point number.
15744 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15746 * print.c (print_object): Print empty symbol as ##.
15748 * lread.c (read1): Read ## as empty symbol.
15750 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15752 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15753 setting frame foreground color (Bug#9175).
15754 (x_set_background_color): Likewise.
15756 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15757 contents (Bug#9176).
15758 (EmacsTooltip -init): Remove bezels and add shadows to
15761 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15762 or scroll bar (Bug#8470).
15764 * nsfont.m (nsfont_open): Remove assignment to voffset and
15765 unnecessary vars hshink, expand, hd, full_height, min_height.
15766 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15768 * nsterm.h (nsfont_info): Remove voffset field.
15770 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15772 Implement strike-through and overline on NextStep (Bug#8863).
15774 * nsfont.m (nsfont_open): Use underline position provided by font,
15775 instead of hard-coded value of 2.
15776 (nsfont_draw): Call ns_draw_text_decoration instead.
15778 * nsterm.h: Add declaration for ns_draw_text_decoration.
15780 * nsterm.m (ns_draw_text_decoration): New function for drawing
15781 underline, overline, and strike-through.
15782 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15783 ns_draw_text_decoration. Change treatment of cursor drawing to
15784 accommodate underlining, etc.
15786 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15788 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15791 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15793 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15794 Without this fix, if a signal arrives just after memory fills up,
15795 'malloc' might be invoked reentrantly.
15797 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15798 In other words, assume that every image size is allowed, on non-X
15799 hosts. This assumption is probably wrong, but it lets Emacs compile.
15801 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15803 * regex.c (re_iswctype): Convert return values to boolean.
15805 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15807 * xdisp.c (compute_display_string_pos): Don't use cached display
15808 string position if the buffer had its restriction changed.
15811 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15813 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15815 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15817 Integer signedness and overflow and related fixes. (Bug#9079)
15819 * bidi.c: Integer size and overflow fixes.
15820 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15821 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15822 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15823 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15824 (bidi_find_other_level_edge):
15825 Use ptrdiff_t instead of EMACS_INT where either will do.
15826 This works better on 32-bit hosts configured --with-wide-int.
15827 (bidi_cache_ensure_space): Check for size-calculation overflow.
15828 Use % rather than repeated addition, for better worst-case speed.
15829 Don't set bidi_cache_size until after xrealloc returns, because it
15831 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15832 (bidi_cache_ensure_space): Also check that the bidi cache size
15833 does not exceed that of the largest Lisp string or buffer. See Eli
15834 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15836 * alloc.c (__malloc_size_t): Remove.
15837 All uses replaced by size_t. See Andreas Schwab's note
15838 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15840 * image.c: Improve checking for integer overflow.
15841 (check_image_size): Assume that f is nonnull, since
15842 it is always nonnull in practice. This is one less thing to
15843 worry about when checking for integer overflow later.
15844 (x_check_image_size): New function, which checks for integer
15845 overflow issues inside X.
15846 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15847 This removes the need for a memory_full check.
15848 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15849 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15850 (xbm_read_bitmap_data): Change locals back to 'int', since
15851 their values must fit in 'int'.
15852 (xpm_load_image, png_load, tiff_load):
15853 Invoke x_create_x_image_and_pixmap earlier,
15854 to avoid much needless work if the image is too large.
15855 (tiff_load): Treat overly large images as if
15856 x_create_x_image_and_pixmap failed, not as malloc failures.
15857 (gs_load): Use x_check_image_size.
15859 * gtkutil.c: Omit integer casts.
15860 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15861 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15863 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15865 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15866 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15867 would wrongly return t on a 64-bit host.
15869 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15870 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15871 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15872 and therefore cause GCC to emit a bogus diagnostic in some cases.
15874 * image.c: Integer signedness and overflow and related fixes.
15875 This is not an exhaustive set of fixes, but it's time to
15876 record what I've got.
15877 (lookup_pixel_color, check_image_size): Remove redundant decls.
15878 (check_image_size): Don't assume that arbitrary EMACS_INT values
15879 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15880 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15881 (tiff_load, imagemagick_load_image):
15882 Check for overflow in size calculations.
15883 (x_create_x_image_and_pixmap): Remove unnecessary test for
15884 xmalloc returning NULL; that can't happen.
15885 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15886 (xpm_color_bucket): Use better integer hashing function.
15887 (xpm_cache_color): Don't possibly over-allocate memory.
15888 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15889 (gif_memory_source):
15890 Use ptrdiff_t, not int or size_t, to record sizes.
15891 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15892 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15893 either works, as we prefer signed integers.
15894 (tiff_read_from_memory, tiff_write_from_memory):
15895 Return tsize_t, not size_t, since that's what the TIFF API wants.
15896 (tiff_read_from_memory): Don't fail simply because the read would
15897 go past EOF; instead, return a short read.
15898 (tiff_load): Omit no-longer-needed casts.
15899 (Fimagemagick_types): Don't assume size fits into 'int'.
15901 Improve hashing quality when configured --with-wide-int.
15902 * fns.c (hash_string): New function, taken from sxhash_string.
15903 Do not discard information about ASCII character case; this
15904 discarding is no longer needed.
15905 (sxhash-string): Use it. Change sig to match it. Caller changed.
15906 * lisp.h: Declare it.
15907 * lread.c (hash_string): Remove, since we now use fns.c's version.
15908 The fns.c version returns a wider integer if --with-wide-int is
15909 specified, so this should help the quality of the hashing a bit.
15911 * emacs.c: Integer overflow minor fix.
15912 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15913 Define only if GNU_LINUX.
15914 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15916 * dispnew.c: Integer signedness and overflow fixes.
15917 Remove unnecessary forward decls, that were a maintenance hassle.
15918 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15920 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15921 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15922 (prepare_desired_row, line_draw_cost):
15923 Use int, not unsigned, where either works.
15924 (save_current_matrix, restore_current_matrix):
15925 Use ptrdiff_t, not size_t, where either works.
15926 (init_display): Check for overflow more accurately, and without
15927 relying on undefined behavior.
15929 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15930 Remove, replacing with the new symbols in lisp.h. All uses changed.
15931 * fileio.c (make_temp_name):
15932 * filelock.c (lock_file_1, lock_file):
15933 * xdisp.c (message_dolog):
15934 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15935 Use pMd etc. instead.
15936 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15937 replacing the pWIDE etc. symbols removed from editfns.c.
15939 * keyboard.h (num_input_events): Now uintmax_t.
15940 This is (very slightly) less likely to mess up due to wraparound.
15943 * buffer.c: Integer signedness fixes.
15944 (alloc_buffer_text, enlarge_buffer_text):
15945 Use ptrdiff_t rather than size_t when either will do, as we prefer
15948 * alloc.c: Integer signedness and overflow fixes.
15949 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15950 (__malloc_size_t): Default to size_t, not to int.
15951 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15952 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15953 Prefer ptrdiff_t to size_t when either would do, as we prefer
15955 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15956 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15957 Now const. Initialize with values that are in range even if char
15959 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15960 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15961 These functions do the right thing with sizes > 2**32.
15962 (check_depth): Now ptrdiff_t, not int.
15963 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15964 Adjust to new way of storing sizes. Check for size overflow bugs
15966 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15967 slightly wrong anyway, as it missed one instance of
15968 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15969 (refill_memory_reserve): Omit needless cast to size_t.
15970 (mark_object_loop_halt): Mark as externally visible.
15972 * xselect.c: Integer signedness and overflow fixes.
15973 (Fx_register_dnd_atom, x_handle_dnd_message):
15974 Use ptrdiff_t, not size_t, since we prefer signed.
15975 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15976 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15977 x_dnd_atoms_size and x_dnd_atoms_length.
15979 * doprnt.c: Prefer signed to unsigned when either works.
15981 * doprnt.c (doprnt):
15983 * xdisp.c (vmessage):
15984 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15985 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15986 prefer signed arithmetic to avoid comparison confusion.
15987 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15988 but is a bit tricky.
15990 Assume freestanding C89 headers, string.h, stdlib.h.
15991 * data.c, doprnt.c, floatfns.c, print.c:
15992 Include float.h unconditionally.
15993 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15994 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15995 * regex.c: Likewise for stddef.h, string.h.
15996 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15997 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15998 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15999 (STDC_HEADERS): Remove obsolete defines.
16000 * sysdep.c: Include limits.h unconditionally.
16002 Assume support for memcmp, memcpy, memmove, memset.
16003 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16004 * regex.c (memcmp, memcpy):
16005 Remove; we assume C89 now.
16007 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16008 (__malloc_safe_bcopy): Remove; no longer needed.
16010 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16011 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16012 well either way, and we prefer signed to unsigned.
16014 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16016 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16017 closes the connection while we're reading (bug#9182).
16019 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16021 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16022 are specified (Bug#9168).
16024 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16026 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16027 Found by GCC static checking and --with-wide-int on a 32-bit host.
16029 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16031 * xdisp.c (compute_display_string_pos): Fix logic of caching
16032 previous display string position. Initialize cached_prev_pos to
16033 -1. Fixes slow-down at the beginning of a buffer.
16035 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16037 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16038 for attrs[LFACE_FONTSET_INDEX].
16040 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16042 * xml.c (parse_region): Remove unused local
16043 that was recently introduced.
16045 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16047 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16048 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16050 * xdisp.c (move_it_in_display_line_to): Record the best matching
16051 position for TO_CHARPOS while scanning the line, and restore it on
16052 exit if none of the characters scanned was an exact match.
16053 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16054 when exact match is impossible due to invisible text, and the
16055 lines are truncated.
16057 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16059 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16062 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16064 Fix a significant slow-down of cursor motion with C-n, C-p,
16065 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16066 auto-repeat under bidi redisplay in fontified buffers.
16067 * xdisp.c (compute_stop_pos_backwards): New function.
16068 (next_element_from_buffer): Call compute_stop_pos_backwards to
16069 find a suitable prev_stop when we find ourselves before
16071 (reseat): Don't look for prev_stop, as that could mean a very long
16073 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16074 <cached_disp_overlay_modiff>: Cache for last found display string
16076 (compute_display_string_pos): Return the cached position if asked
16077 about the same buffer in the same area of character positions, and
16078 the buffer wasn't changed since the time the display string
16079 position was cached.
16081 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16083 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16084 is an integer, which is important for empty lines. (Bug#9149)
16086 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16088 * frame.c (Fmodify_frame_parameters): In tty case, update the
16089 default face if necessary (Bug#4238).
16091 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16093 * editfns.c (Fstring_to_char): No need to explain what a character
16094 is in the docstring (Bug#6576).
16096 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16098 * xml.c (parse_region): Make sure we always return a tree.
16100 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16102 * xml.c (parse_region): If a document contains only comments,
16105 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16107 * xml.c (make_dom): Return comments, too.
16109 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16112 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16113 and the surrounding thread.
16114 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16115 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16116 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16118 * s/openbsd.h (BROKEN_SIGIO): Define.
16119 * unexelf.c (unexec) [__OpenBSD__]:
16120 Don't update the .mdebug section of the Alpha COFF symbol table.
16122 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16124 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16127 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16129 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16130 This fixes some race conditions on the permissions of any newly
16133 * alloc.c (valid_pointer_p): Use pipe, not open.
16134 This fixes some permissions issues when debugging.
16136 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16137 If fchown fails to set both uid and gid, try to set just gid,
16138 as that is sometimes allowed. Adjust the file's mode to eliminate
16139 setuid or setgid bits that are inappropriate if fchown fails.
16141 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16143 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16149 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16151 * lread.c (read_integer): Unread even EOF character.
16152 (read1): Likewise. Properly record start position of symbol.
16154 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16155 symbol character follows.
16157 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16159 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16160 This works around a problem with the previous change to Fcopy_file.
16161 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16162 and without this change, GCC might complain about discarding
16163 fchown's return value.
16165 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16167 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16169 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16171 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16173 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16175 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16176 it's used from the C level.
16178 * process.c: Use the same condition for POLL_FOR_INPUT in both
16179 keyboard.c and process.c (bug#1858).
16181 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16183 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16184 (Fgnutls_boot): Use it.
16186 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16188 * doc.c (Fsubstitute_command_keys): Revert last change.
16190 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16192 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16193 quotes the next character, and doesn't affect other longer
16194 sequences (bug#8935).
16196 * lread.c (syms_of_lread): Clarify that is isn't only
16197 `eval-buffer' and `eval-defun' that's affected by
16198 `lexical-binding' (bug#8460).
16200 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16202 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16203 bidi redisplay when a line includes both an image and is truncated.
16205 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16207 Fix minor problems found by static checking.
16208 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16209 (elsz): Now a signed constant, not a size_t var. We prefer signed
16210 types to unsigned, to avoid integer comparison confusion. Without
16211 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16212 "cannot optimize loop, the loop counter may overflow", a symptom
16214 * indent.c (Fvertical_motion): Mark locals as initialized.
16215 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16217 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16219 * search.c (Fre_search_backward): Mention `case-fold-search' in
16220 all the re_search_* functions (bug#8138).

16240 buffer position was specified. Initialize paragraph_embedding to
16242 (reseat_to_string): Initialize the bidi iterator.
16243 (display_string): If we need to ignore text properties of
16244 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16245 original value of -1 will not work with bidi.)
16246 (compute_display_string_pos): First arg is now struct
16247 `text_pos *'; all callers changed. Support display properties on
16249 (compute_display_string_end): Support display properties on Lisp
16251 (init_iterator, reseat_1, reseat_to_string): Initialize the
16252 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16253 when iterating on a string not from display properties).
16254 (compute_display_string_pos, compute_display_string_end):
16255 Fix calculation of the object to scan. Fixes an error when using
16257 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16258 base_level_stop; instead, set base_level_stop to BEGV.
16259 Fixes crashes in vertical-motion.
16260 (next_element_from_buffer): Improve commentary for when
16261 the iterator is before prev_stop.
16262 (init_iterator): Initialize bidi_p from the default value of
16263 bidi-display-reordering, not from buffer-local value. Use the
16264 buffer-local value only if initializing for buffer iteration.
16265 (handle_invisible_prop): Support invisible properties on strings
16266 that are being bidi-reordered.
16267 (set_iterator_to_next): Support bidi reordering of C strings and

16273 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16274 (init_iterator): Don't initialize it->bidi_p for strings
16276 (reseat_to_string): Initialize it->bidi_p for strings here.

16284 (get_visually_first_element): New function, refactored from common
16285 parts of next_element_from_buffer, next_element_from_string, and
16286 next_element_from_c_string.
16287 (tool_bar_lines_needed, redisplay_tool_bar)
16288 (display_menu_bar): Force left-to-right direction. Add a FIXME
16289 comment for making that be controlled by a user option.
16290 (push_it, pop_it): Save and restore the state of the
16291 bidi iterator. Save and restore the bidi_p flag.
16292 (pop_it): Iterate out of display property for string iteration as

16295 (handle_single_display_spec): Set up it->bidi_it for iteration
16296 over a display string, and call bidi_init_it.

16298 (get_overlay_strings_1, push_display_prop): Set up the bidi
16299 iterator for displaying display or overlay strings.
16300 (forward_to_next_line_start): Don't use the shortcut if
16302 (back_to_previous_visible_line_start): If handle_display_prop
16303 pushed the iterator stack, restore the internal state of the bidi
16304 iterator by calling bidi_pop_it same number of times.
16305 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16306 and we are bidi-iterating, don't decrement the iterator position;
16307 instead, set the first_elt flag in the bidi iterator, to produce
16309 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16310 (push_display_prop): xassert that we are iterating a buffer.
16311 (push_it, pop_it): Save and restore paragraph_embedding member.
16312 (handle_single_display_spec, next_overlay_string)
16313 (get_overlay_strings_1, reseat_1, reseat_to_string)
16314 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16315 correctly. Don't assume unibyte strings are not bidi-reordered.
16316 (compute_display_string_pos)
16317 (compute_display_string_end): Fix handling the case of C string.
16318 (push_it, pop_it): Save and restore from_disp_prop_p.

16322 (pop_it): Call iterate_out_of_display_property only if we are
16323 popping after iteration over a string that came from a display
16324 property. Fix a typo in popping stretch info. Add an assertion
16325 for verifying that the iterator position is in sync with the bidi
16327 (handle_single_display_spec, get_overlay_strings_1)
16328 (push_display_prop): Fix initialization of paragraph direction for
16329 string when that of the parent object is not yet determined.

16331 iterator with IT's position. (Bug#7616)
16332 (find_row_edges): If ROW->start.pos gives position
16333 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

16335 Reset the from_disp_prop_p flag.
16336 (SAVE_IT, RESTORE_IT): New macros.

16341 (try_scrolling, redisplay_window, display_line): Use them when
16342 saving a temporary copy of the iterator and restoring it back.
16343 (back_to_previous_visible_line_start, reseat_1)
16344 (init_iterator): Empty the bidi cache "stack".
16345 (move_it_in_display_line_to): If iterator ended up at
16346 EOL, but we never saw any buffer positions smaller than
16347 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor

16351 motion in bidi-reordered lines with stretch glyphs and strings
16352 displayed in margins. (Bug#8133) (Bug#8867)
16353 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16355 (pos_visible_p): Support positions in bidi-reordered lines.
16356 Save and restore bidi cache.
16358 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16359 (bidi_paragraph_info): Delete unused struct.

16377 Support iteration over a string.
16378 (bidi_set_sor_type, bidi_resolve_explicit_1)
16379 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
16380 can now be zero (for strings); special values 0 and -1 were
16381 changed to -1 and -2, respectively.
16382 (bidi_char_at_pos): New function.
16383 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16394 (bidi_initialize): Initialize the bidi cache start stack pointer.
16395 (bidi_cache_ensure_space): New function, refactored from part of

16411 * dispextern.h (struct bidi_string_data): New structure.
16412 (struct bidi_it): New member `string'. Make flag members be 1-bit
16413 fields, and put them last in the struct.
16414 (compute_display_string_pos, compute_display_string_end):
16416 (bidi_push_it, bidi_pop_it): Add prototypes.
16417 (struct iterator_stack_entry): New members bidi_p,
16418 paragraph_embedding, and from_disp_prop_p.
16419 (struct it): Member bidi_p is now a bit field 1 bit wide.
16420 (bidi_shelve_cache, bidi_unshelve_cache):
16421 Declare prototypes.
16423 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

16441 * indent.c (Fvertical_motion): Set and restore w->pointm when
16442 saving and restoring the window's buffer (Bug#9006).

16465 (x_handle_selection_clear,x_clear_frame_selections):
16466 Pass Qx_lost_selection_functions rather than
16467 Vx_lost_selection_functions to Frun_hook_with_args.
16469 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16471 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16472 The old code sometimes used this field without initializing it.
16474 * alloc.c (gc_sweep): Don't read past end of array.
16475 In theory, the old code could also have corrupted Emacs internals,

16781 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16782 subseconds part to the entropy, as that's a bit more random.
16783 Prefer signed to unsigned, since the signedness doesn't matter and
16784 in general we prefer signed. When given a limit, use a
16785 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16786 latter isn't right if USE_2_TAGS_FOR_INTS.
16787 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16788 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16801 This is more efficient than Ffile_directory_p and avoids a minor race.

16805 * buffer.c (Foverlay_put): Say what the return value is

16831 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

16931 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
16933 * eval.c (struct backtrace): Simplify and port the data structure.
16934 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16935 signed bit field, as this assumption is not portable and it makes
16936 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16937 "char debug_on_exit : 1" as this is not portable either; instead,
16938 use the portable "unsigned int debug_on_exit : 1". Remove unused
16939 member evalargs. Remove obsolete comments about cc bombing out.
16941 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17009 (emacs_fixed_new): Set priv->f to argument.
17010 (emacs_fixed_get_preferred_width)
17011 (emacs_fixed_get_preferred_height): Use min_width/height from
17012 frames size_hint to set minimum and natural (Bug#8919).
17013 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17014 and use min_width/height from frames size_hint to set
17015 min_width/height (Bug#8919).

17035 Use gnulib's dup2 module instead of rolling our own.
17036 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

17103 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17105 Integer and buffer overflow fixes (Bug#8873).
17107 * print.c (printchar, strout): Check for string overflow.
17108 (PRINTPREPARE, printchar, strout):
17109 Don't set size unless allocation succeeds.
17111 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17112 for sizes. Check for string overflow more accurately.
17113 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17115 * macros.c: Integer and buffer overflow fixes.
17116 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17117 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17121 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17123 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17125 * lread.c: Integer overflow fixes.
17126 (read_integer): Radix is now EMACS_INT, not int,
17127 to improve quality of diagnostics for out-of-range radices.
17128 Calculate buffer size correctly for out-of-range radices.
17129 (read1): Check for integer overflow in radices, and in
17130 read-circle numbers.
17131 (read_escape): Avoid int overflow.
17132 (Fload, openp, read_buffer_size, read1)
17133 (substitute_object_recurse, read_vector, read_list, map_obarray):
17134 Use ptrdiff_t, not int, for sizes.

17149 2011-06-22 Leo Liu <sdl.web@gmail.com>
17151 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17152 Move to minibuffer.el.
17154 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17156 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17157 The following patches are for when GLYPH_DEBUG && !XASSERT.
17158 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17159 * dispnew.c (flush_stdout):
17160 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17161 Mark as externally visible.
17162 * dispnew.c (check_window_matrix_pointers): Now static.
17163 * dispnew.c (window_to_frame_vpos):
17164 * xfns.c (unwind_create_frame):
17165 * xterm.c (x_check_font): Remove unused local.
17166 * scroll.c (CHECK_BOUNDS):
17167 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17168 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17169 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17170 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17171 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17173 (debug_method_add): Use va_list and vsprintf rather than relying
17174 on undefined behavior with wrong number of arguments.
17175 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17176 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17177 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17178 since we're not interested in debugging glyphs with old libraries.
17179 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17180 GCC 4.6.0's static checking.
17182 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17184 Integer overflow and signedness fixes (Bug#8873).

17195 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17196 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17198 * xfaces.c (load_pixmap):
17199 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17200 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17201 (.bitmaps_last, struct x_output.icon_bitmap):
17202 Use ptrdiff_t, not int, for bitmap indexes.
17203 (x_allocate_bitmap_record): Check for size overflow.
17204 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17206 Use ptrdiff_t, not int, for overlay counts.
17207 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17208 * editfns.c (overlays_around, get_pos_property):
17209 * textprop.c (get_char_property_and_overlay):
17210 * xdisp.c (next_overlay_change, note_mouse_highlight):
17211 * xfaces.c (face_at_buffer_position):
17212 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17213 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17214 (Fnext_overlay_change, Fprevious_overlay_change)
17215 (mouse_face_overlay_overlaps, Foverlays_in):
17216 Use ptrdiff_t, not int, for sizes.
17217 (overlays_at, overlays_in): Check for size-calculation overflow.
17219 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17221 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17222 (x_session_initialize): Do not assume string length fits in int.
17224 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17225 This is unlikely, but can occur if DPI is outlandish.
17227 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17228 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17230 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17231 * xrdb.c (magic_file_p, search_magic_path):
17232 Omit last arg SUFFIX; it was always 0. All callers changed.
17233 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17235 * xfont.c (xfont_match): Avoid need for strlen.
17237 * xfns.c: Don't assume strlen fits in int.
17238 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17240 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17241 not unsigned long, as we prefer signed integers. All callers changed.
17242 Detect integer overflow in repeat count.
17243 (message_dolog): Don't assume print length fits in 39 bytes.
17244 (display_mode_element): Don't assume strlen fits in int.
17246 * termcap.c: Don't assume sizes fit in int and never overflow.
17247 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17248 (gobble_line): Check for size-calculation overflow.
17250 * minibuf.c (Fread_buffer):
17251 * lread.c (intern, intern_c_string):
17252 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17253 Don't assume string length fits in int.
17255 * keyboard.c (parse_tool_bar_item):
17256 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17258 * font.c: Don't assume string length fits in int.
17259 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):

17262 Don't assume integer property fits in fixnum.
17263 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17265 * filelock.c: Fix some buffer overrun and integer overflow issues.
17266 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17267 Reformulate so as not to need the command string.
17268 Invoke gzip -cd rather than gunzip, as it's more portable.
17269 (lock_info_type, lock_file_1, lock_file):
17270 Don't assume pid_t and time_t fit in unsigned long.
17271 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17272 (current_lock_owner): Prefer signed type for sizes.
17273 Use memcpy, not strncpy, where memcpy is what is really wanted.
17274 Don't assume (via atoi) that time_t and pid_t fit in int.
17275 Check for time_t and/or pid_t out of range, e.g., via a network share.
17276 Don't alloca where an auto var works fine.
17278 * fileio.c: Fix some integer overflow issues.
17279 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17280 Don't assume string length fits in int.
17281 (directory_file_name): Don't assume string length fits in long.
17282 (make_temp_name): Don't assume pid fits in int, or that its print
17283 length is less than 20.
17285 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17287 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17289 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17291 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17292 We prefer signed integers, even for size calculations.
17294 * emacs.c: Don't assume string length fits in 'int'.
17295 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17296 (main): Don't invoke strlen when not needed.

17301 * callproc.c (getenv_internal_1, getenv_internal)
17302 (Fgetenv_internal):
17303 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17305 * lread.c (invalid_syntax): Omit length argument.
17306 All uses changed. This doesn't fix a bug, but it simplifies the
17307 code away from its former Hollerith-constant appearance, and it's
17308 one less 'int' to worry about when looking at integer-overflow issues.
17309 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17311 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17312 This didn't break anything, but it didn't help either.
17313 It's confusing to put a bogus integer in a place where the actual
17314 value does not matter.
17315 (LIST_END_P): Remove unused macro and its bogus comment.
17316 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17318 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17319 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17321 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17322 We prefer signed types, and the value cannot exceed the EMACS_INT
17323 range anyway (because otherwise the length would not be representable).
17324 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17325 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17326 This avoids a GCC warning when WIDE_EMACS_INT.
17328 * indent.c (sane_tab_width): New function.
17329 (current_column, scan_for_column, Findent_to, position_indentation)
17330 (compute_motion): Use it. This is just for clarity.
17331 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17333 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17335 * lisp.h (lint_assume): New macro.
17336 * composite.c (composition_gstring_put_cache):
17337 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17339 * editfns.c, insdel.c:
17340 Omit unnecessary forward decls, to simplify future changes.
17342 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17344 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17346 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17347 Use much-faster test for byte-length change.
17348 Don't assume string byte-length fits in 'int'.
17349 Check that character arg fits in 'int'.
17350 (mapcar1): Declare byte as byte, for clarity.
17352 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17354 * fns.c (concat): Catch string overflow earlier.
17355 Do not rely on integer wraparound.
17357 * dispextern.h (struct it.overlay_strings_charpos)
17358 (struct it.selective): Now EMACS_INT, not int.
17359 * xdisp.c (forward_to_next_line_start)
17360 (back_to_previous_visible_line_start)
17361 (reseat_at_next_visible_line_start, next_element_from_buffer):
17362 Don't arbitrarily truncate the value of 'selective' to int.
17364 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17366 * composite.c: Don't truncate sizes to 'int'.
17367 (composition_gstring_p, composition_reseat_it)
17368 (composition_adjust_point): Use EMACS_INT, not int.
17369 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17370 not EMACS_UINT, for indexes.
17372 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17374 * buffer.c: Include <verify.h>.
17375 (struct sortvec.priority, struct sortstr.priority):
17376 Now EMACS_INT, not int.
17377 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17378 (struct sortstr.size, record_overlay_string)
17379 (struct sortstrlist.size, struct sortlist.used):
17380 Don't truncate size to int.
17381 (record_overlay_string): Check for size-calculation overflow.
17382 (init_buffer_once): Check at compile-time, not run-time.
17384 2011-06-22 Jim Meyering <meyering@redhat.com>
17386 Don't leak an XBM-image-sized buffer
17387 * image.c (xbm_load): Free the image buffer after using it.
17389 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17392 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17393 that Sun C diagnosed.
17394 * fns.c (secure_hash): Fix pointer signedness issue.
17395 * intervals.c (static_offset_intervals): New function.
17396 (offset_intervals): Use it.
17398 2011-06-21 Leo Liu <sdl.web@gmail.com>
17401 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17404 * fns.c (secure_hash): Rename from crypto_hash_function and change
17405 the first arg to accept symbols.
17406 (Fsecure_hash): New primitive.
17407 (syms_of_fns): New symbols.
17409 2011-06-20 Deniz Dogan <deniz@dogan.se>
17411 * process.c (Fset_process_buffer): Clarify return value in
17414 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17416 * dispnew.c (add_window_display_history): Use BVAR.
17418 * xdisp.c (debug_method_add): Use BVAR.
17419 (check_window_end, dump_glyph_matrix, dump_glyph)
17420 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17422 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17425 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17426 check till after the cache is created in init_frame_faces.
17428 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17430 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17432 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17434 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17435 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17436 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17438 Improve buffer-overflow checking (Bug#8873).
17439 * fileio.c (Finsert_file_contents):
17440 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17441 Remove the old (too-loose) buffer overflow checks.
17442 They weren't needed, since make_gap checks for buffer overflow.
17443 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17444 The old code merely checked for Emacs fixnum overflow, and relied
17445 on undefined (wraparound) behavior. The new code avoids undefined
17446 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17448 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17449 Tune. Don't use wider integers than needed. Don't use alloca.
17450 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17452 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17454 * insdel.c, lisp.h (buffer_overflow): New function.
17455 (insert_from_buffer_1, replace_range, replace_range_2):
17456 * insdel.c (make_gap_larger):
17457 * editfns.c (Finsert_char):
17458 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17460 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17462 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17464 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17466 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17467 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17469 * fileio.c: Don't assume EMACS_INT fits in off_t.
17470 (emacs_lseek): New static function.
17471 (Finsert_file_contents, Fwrite_region): Use it.
17472 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17474 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17476 * fns.c: Don't overflow int when computing a list length.
17477 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17478 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17479 truncation on 64-bit hosts. Check for QUIT every
17480 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17481 faster and is responsive enough.
17482 (Flength): Report an error instead of overflowing an integer.
17483 (Fsafe_length): Return a float if the value is not representable
17484 as a fixnum. This shouldn't happen except in contrived situations.
17485 (Fnthcdr, Fsort): Don't assume list length fits in int.
17486 (Fcopy_sequence): Don't assume vector length fits in int.
17488 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17489 (header_size, word_size): New constants.
17490 (allocate_vectorlike): Don't check size overflow here.
17491 (allocate_vector): Check it here instead, since this is the only
17492 caller of allocate_vectorlike that could cause overflow.
17493 Check that the new vector's length is representable as a fixnum.
17495 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17496 The previous code was bogus. For example, next_almost_prime (32)
17497 returned 39, which is undesirable as it is a multiple of 3; and
17498 next_almost_prime (24) returned 25, which is a multiple of 5 so
17499 why was the code bothering to check for multiples of 7?
17501 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17503 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17505 Variadic C functions now count arguments with ptrdiff_t.
17506 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17507 Back then I didn't know that the Emacs coding style prefers signed int.
17508 Also, in the meantime I found a few more instances where arguments
17509 were being counted with int, which may truncate counts on 64-bit
17510 machines, or EMACS_INT, which may be unnecessarily wide.
17511 * lisp.h (struct Lisp_Subr.function.aMANY)
17512 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17513 Arg counts are now ptrdiff_t, not size_t.
17514 All variadic functions and their callers changed accordingly.
17515 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17516 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17517 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17518 * callint.c (Fcall_interactively): Check arg count for overflow,
17519 to avoid potential buffer overrun. Use signed char, not 'int',
17520 for 'varies' array, so that we needn't bother to check its size
17521 calculation for overflow.
17522 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17523 * eval.c (apply_lambda):
17524 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17525 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17526 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17528 * callint.c (Fcall_interactively): Don't use index var as event count.
17530 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17531 * mem-limits.h (SIZE): Remove; no longer used.
17533 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17535 Remove unnecessary casts.
17536 * xterm.c (x_term_init):
17537 * xfns.c (x_set_border_pixel):
17538 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17539 These aren't needed now that we assume ANSI C.
17541 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17542 It's more likely to cause problems (due to unsigned overflow)
17545 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17547 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17549 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17551 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17553 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17555 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17557 GLYPH_CODE_FACE returns EMACS_INT, not int.
17558 * dispextern.h (merge_faces):
17559 * xfaces.c (merge_faces):
17560 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17561 Don't assume EMACS_INT fits in int.
17563 * character.h (CHAR_VALID_P): Remove unused parameter.
17564 * fontset.c, lisp.h, xdisp.c: All uses changed.
17566 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17568 * fns.c (concat): Minor tuning based on overflow analysis.
17569 This doesn't fix any bugs. Use int to hold character, instead
17570 of constantly refetching from Emacs object. Use XFASTINT, not
17571 XINT, for value known to be a character. Don't bother comparing
17572 a single byte to 0400, as it's always less.
17574 * floatfns.c (Fexpt):
17575 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17577 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17580 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17582 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17583 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17584 incorrectly succeed when S was a string, because 4294967386 was
17585 truncated before it was used.
17587 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17588 Otherwise, an out-of-range integer could cause undefined behavior
17591 * composite.c: Use int, not EMACS_INT, for characters.
17592 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17593 EMACS_INT, for values that are known to be in character range.
17594 This doesn't fix any bugs but is the usual style inside Emacs and
17595 may generate better code on 32-bit machines.
17597 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17598 This is for reasons similar to the recent CHAR_STRING fix.
17599 * charset.c (Fencode_char): Check that character arg is actually
17600 a character. Pass an int to ENCODE_CHAR.
17601 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17602 wider than 'int', as a compile-time check to prevent future regressions
17605 * character.c (char_string): Remove unnecessary casts.
17607 Make sure a 64-bit char is never passed to CHAR_STRING.
17608 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17609 by silently ignoring the top 32 bits, allowing some values
17610 that were far too large to be valid characters.
17611 * character.h: Include <verify.h>.
17612 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17613 arguments are no wider than unsigned, as a compile-time check
17614 to prevent future regressions in this area.
17616 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17617 (Fsubst_char_in_region):
17619 * xdisp.c (decode_mode_spec_coding):
17620 Adjust to CHAR_STRING's new requirement.
17621 * editfns.c (Finsert_char, Fsubst_char_in_region):
17622 * fns.c (concat): Check that character args are actually
17623 characters. Without this test, these functions did the wrong
17624 thing with wildly out-of-range values on 64-bit hosts.
17626 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17627 These casts should not be needed on 32-bit hosts, either.
17628 * keyboard.c (read_char):
17629 * lread.c (Fload): Remove casts to unsigned.
17631 * lisp.h (UNSIGNED_CMP): New macro.
17632 This fixes comparison bugs on 64-bit hosts.
17633 (ASCII_CHAR_P): Use it.
17634 * casefiddle.c (casify_object):
17635 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17636 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17637 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17638 * dispextern.h (FACE_FROM_ID):
17639 * keyboard.c (read_char): Use UNSIGNED_CMP.
17641 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17642 not to EMACS_INT, to avoid GCC warning.
17644 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17646 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17647 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17648 isn't needed on 32-bit machines.
17650 * buffer.c (Fgenerate_new_buffer_name):
17651 Use EMACS_INT for count, not int.
17652 (advance_to_char_boundary): Return EMACS_INT, not int.
17654 * data.c (Qcompiled_function): Now static.
17656 * window.c (window_body_lines): Now static.
17658 * image.c (gif_load): Rename local to avoid shadowing.
17660 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17661 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17662 * alloc.c (make_save_value): Integer argument is now of type
17663 ptrdiff_t, not int.
17664 (mark_object): Use ptrdiff_t, not int.
17665 * lisp.h (pD): New macro.
17666 * print.c (print_object): Use it.
17668 * alloc.c: Use EMACS_INT, not int, to count objects.
17669 (total_conses, total_markers, total_symbols, total_vector_size)
17670 (total_free_conses, total_free_markers, total_free_symbols)
17671 (total_free_floats, total_floats, total_free_intervals)
17672 (total_intervals, total_strings, total_free_strings):
17673 Now EMACS_INT, not int. All uses changed.
17674 (Fgarbage_collect): Compute overall total using a double, so that
17675 integer overflow is less likely to be a problem. Check for overflow
17676 when converting back to an integer.
17677 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17678 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17679 These were 'int' variables that could overflow on 64-bit hosts;
17680 they were never used, so remove them instead of repairing them.
17681 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17682 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17683 Previously, this ceilinged at INT_MAX, but that doesn't work on
17685 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17687 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17688 (allocate_vectorlike): Check for ptrdiff_t overflow.
17689 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17690 when a (possibly-narrower) signed value would do just as well.
17691 We prefer using signed arithmetic, to avoid comparison confusion.
17693 * alloc.c: Catch some string size overflows that we were missing.
17694 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17695 for convenience in STRING_BYTES_MAX.
17696 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17697 The definition here is exact; the one in lisp.h was approximate.
17698 (allocate_string_data): Check for string overflow. This catches
17699 some instances we weren't catching before. Also, it catches
17700 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17701 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17702 and ptrdiff_t and EMACS_INT are both 64 bits.
17704 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17705 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17706 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17708 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17710 * alloc.c (Fmake_string): Check for out-of-range init.
17712 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17714 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17716 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17718 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17719 xg_get_default_scrollbar_width.
17721 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17722 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17723 (style_changed_cb): Call update_theme_scrollbar_width and call
17724 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17725 all frames (Bug#8505).
17726 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17727 Call gtk_window_set_resizable if HAVE_GTK3.
17728 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17729 and height if HAVE_GTK3 (Bug#8505).
17730 (scroll_bar_width_for_theme): New variable.
17731 (update_theme_scrollbar_width): New function.
17732 (xg_get_default_scrollbar_width): Move code to
17733 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17734 (xg_initialize): Call update_theme_scrollbar_width.
17736 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17738 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17740 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17742 * frame.c (make_frame): Call other_buffer_safely instead of
17745 * window.c (temp_output_buffer_show): Call display_buffer with
17746 second argument Vtemp_buffer_show_specifiers and reset latter
17747 immediately after the call.
17748 (Vtemp_buffer_show_specifiers): New variable.
17749 (auto_window_vscroll_p, next_screen_context_lines)
17750 (Vscroll_preserve_screen_position): Remove leading asterisks from
17753 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17755 Fix minor problems found by GCC 4.6.0 static checking.
17756 * buffer.c (Qclone_number): Remove for now, as it's unused.
17757 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17758 (record_buffer): Remove unused local.
17759 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17760 (set_frame_buffer_list): Remove; unused.
17761 * frame.h (other_visible_frames): Remove decl.
17762 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
17763 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
17764 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
17766 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
17767 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
17768 Define only if HAVE_GPM.
17769 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
17770 (update_hints_inhibit): Remove; never set. All uses removed.
17771 * widgetprv.h (emacsFrameClassRec): Remove decl.
17772 * window.c (delete_deletable_window): Now returns void, since it
17773 wasn't returning anything.
17774 (compare_window_configurations): Remove unused locals.
17775 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
17776 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
17777 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
17778 the same widths as pointers. This follows up on the 2011-05-06 patch.
17779 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
17780 * xterm.h: Likewise.
17781 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
17783 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
17785 * makefile.w32-in: Update dependencies.
17786 (LISP_H): Add lib/intprops.h.
17788 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
17790 * image.c (gif_load): Add animation frame delay to the metadata.
17791 (syms_of_image): Use DEFSYM. New symbol `delay'.
17793 2011-06-11 Martin Rudalics <rudalics@gmx.at>
17795 * window.c (delete_deletable_window): Re-add.

18249 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
18251 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
18253 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
18255 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18257 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
18258 in the current matrix if keep_current_p is non-zero.
18260 2011-06-04 Eli Zaretskii <eliz@gnu.org>
18262 * bidi.c (bidi_level_of_next_char): Fix last change.
18264 2011-06-03 Eli Zaretskii <eliz@gnu.org>
18266 Support bidi reordering of text covered by display properties.
18268 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
18269 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
18270 (bidi_cache_search, bidi_cache_iterator_state)
18271 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
18272 (bidi_level_of_next_char, bidi_move_to_visually_next):
18273 Support character positions inside a run of characters covered by a
18275 (bidi_paragraph_init, bidi_resolve_explicit_1)
18276 (bidi_level_of_next_char): Call bidi_fetch_char and
18277 bidi_fetch_char_advance instead of FETCH_CHAR and
18278 FETCH_CHAR_ADVANCE.
18279 (bidi_init_it): Initialize new members.
18280 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
18282 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
18283 instead of using explicit *_CHAR codes.
18284 (bidi_resolve_explicit, bidi_resolve_weak):
18285 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18286 bidirectional text is supported only in multibyte buffers.
18287 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
18288 it to initialize the frame_window_p member of struct bidi_it.
18289 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
18290 (bidi_resolve_explicit, bidi_resolve_weak)
18291 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
18292 bidi_it->nchars is non-positive.
18293 (bidi_level_of_next_char): Don't try to lookup the cache for the
18294 next/previous character if nothing is cached there yet, or if we
18295 were just reseat()'ed to a new position.
18297 * xdisp.c (set_cursor_from_row): Set start and stop points
18298 according to the row's direction when priming the loop that looks
18299 for the glyph on which to display cursor.
18300 (single_display_spec_intangible_p): Function deleted.
18301 (display_prop_intangible_p): Reimplement to call
18302 handle_display_spec instead of single_display_spec_intangible_p.
18303 Accept 3 additional arguments needed by handle_display_spec.
18304 This fixes incorrect cursor motion across display property with complex
18305 values: lists, `(when COND...)' forms, etc.
18306 (single_display_spec_string_p): Support property values that are
18307 lists with the argument STRING its top-level element.
18308 (display_prop_string_p): Fix the condition for processing a
18309 property that is a list to be consistent with handle_display_spec.
18310 (handle_display_spec): New function, refactored from the
18311 last portion of handle_display_prop.
18312 (compute_display_string_pos): Accept additional argument
18313 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18314 value of a `display' property is a "replacing spec".
18315 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18316 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18317 the display property, but just return a value indicating whether
18318 the display property will replace the characters it covers.
18319 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18320 frame_window_p members of struct bidi_it.
18321 (compute_display_string_pos, compute_display_string_end):
18323 (push_it): Accept second argument POSITION, where pop_it should
18324 jump to continue iteration.
18325 (reseat_1): Initialize bidi_it.disp_pos.
18327 * keyboard.c (adjust_point_for_property): Adjust the call to
18328 display_prop_intangible_p to its new signature.
18330 * dispextern.h (struct bidi_it): New member frame_window_p.
18331 (bidi_init_it): Update prototypes.
18332 (display_prop_intangible_p): Update prototype.
18333 (compute_display_string_pos, compute_display_string_end):
18334 Declare prototypes.
18335 (struct bidi_it): New members nchars and disp_pos. ch_len is now
18338 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18340 Malloc failure behavior now depends on size of allocation.
18341 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18342 * lisp.h: Change signatures accordingly.
18343 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18344 All callers changed. (Bug#8762)
18346 * gnutls.c: Use Emacs's memory allocators.
18347 Without this change, the gnutls library would invoke malloc etc.
18348 directly, which causes problems on non-SYNC_INPUT hosts, and which
18349 runs afoul of improving memory_full behavior. (Bug#8761)
18350 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18351 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18352 xfree instead of the default malloc, realloc, free.
18353 (Fgnutls_boot): No need to check for memory allocation failure,
18354 since xmalloc does that for us.
18356 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18357 * category.c (hash_get_category_set):
18358 * ccl.c (ccl_driver):
18359 * charset.c (Fdefine_charset_internal):
18360 * charset.h (struct charset.hash_index):

18369 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
18370 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18371 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18372 * image.c (make_image, search_image_cache, lookup_image)
18373 (xpm_put_color_table_h):
18374 * lisp.h (struct Lisp_Hash_Table):
18375 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18376 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18377 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18378 * alloc.c (allocate_vectorlike):
18379 Check for overflow in vector size calculations.
18380 * ccl.c (ccl_driver):
18381 Check for overflow when converting EMACS_INT to int.
18382 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18383 need to be updated by these changes.
18384 * fns.c (make_hash_table, maybe_resize_hash_table):
18385 Check for integer overflow with large hash tables.
18386 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18387 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18388 (SXHASH_REDUCE): New macro.
18389 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18390 Use it instead of discarding useful hash info with large hash values.
18391 (sxhash_float): New function.
18392 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18393 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18394 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18395 Rewrite to use FIXNUM_BITS, as this simplifies things.
18396 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18397 Adjust signatures to match updated version of code.
18398 (consing_since_gc): Now EMACS_INT, since a single hash table can
18399 use more than INT_MAX bytes.
18401 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18403 Make it possible to build with GCC-4.6+ -O2 -flto.
18405 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18407 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18409 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18410 Call minibuffer-inactive-mode.
18412 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18414 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18415 Update dependencies.
18417 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18419 * data.c (init_data): Remove code for UTS, this system is not
18422 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18424 Don't force ./temacs to start in terminal mode.
18426 * frame.c (make_initial_frame): Initialize faces in all cases, not
18427 only when CANNOT_DUMP is defined.
18428 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18430 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18432 * dispnew.c (add_window_display_history): Use const for the string
18433 pointer. Remove declaration, not needed.
18435 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18437 Use 'inline', not 'INLINE'.
18438 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18439 * alloc.c, fontset.c (INLINE): Remove.
18440 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18441 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18442 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18443 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18444 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18446 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18448 Make it possible to run ./temacs.
18450 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18451 syms_of_callproc does the same thing. Remove test for
18452 "initialized", do it in the caller.
18453 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18455 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18457 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18458 (read_minibuf): Use get_minibuffer.
18459 (syms_of_minibuf): Use DEFSYM.
18460 (Qmetadata): New var.
18461 * data.c (Qbuffer): Don't make it static.
18462 (syms_of_data): Use DEFSYM.
18464 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18466 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18467 (CCL_CODE_MIN): New macro.
18469 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18471 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18473 * eval.c (Qdebug): Now static.
18474 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18475 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18476 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18478 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18480 * image.c: Various fixes to ImageMagick code comments.
18481 (Fimagemagick_types): Doc fix.
18483 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18485 Minor fixes prompted by GCC 4.6.0 warnings.
18487 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18489 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18490 (x_clipboard_manager_save_all): Move extern decl to ...
18491 * xterm.h: ... here, so that it can be checked for consistency.
18493 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18495 * xselect.c (x_clipboard_manager_save_frame)
18496 (x_clipboard_manager_save_all): New functions.
18497 (Fx_clipboard_manager_save): Lisp function deleted.
18499 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18500 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18502 * xterm.h: Update prototype.
18504 2011-05-28 William Xu <william.xwl@gmail.com>
18506 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18507 exiting (Bug#8239).
18509 2011-05-28 Jim Meyering <meyering@redhat.com>
18511 Avoid a sign-extension bug in crypto_hash_function.
18512 * fns.c (to_uchar): Define.
18513 (crypto_hash_function): Use it to convert some newly-signed
18514 variables to unsigned, to avoid sign-extension bugs. For example,
18515 without this change, (md5 "truc") would evaluate to
18516 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18517 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18518 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18520 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18522 Integer overflow fixes.
18524 * dbusbind.c: Serial number integer overflow fixes.
18525 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18526 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18527 to hold a serial number that is too large for a fixnum.
18528 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18529 Check for serial numbers out of range. Decode any serial number
18530 that was so large that it became a float. (Bug#8722)
18532 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18533 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18534 Use XFASTINT rather than XUINT when numbers are nonnegative.
18535 (xd_append_arg, Fdbus_method_return_internal):
18536 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18537 arguments, check that Lisp number is nonnegative, rather than
18538 silently wrapping negative numbers around. (Bug#8722)
18539 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18542 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18544 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18546 ccl: Add integer overflow checks.
18547 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18548 (IN_INT_RANGE): New macros.
18549 (ccl_driver): Use them to check for integer overflow when
18550 decoding a CCL program. Many of the new checks are whether XINT (x)
18551 fits in int; it doesn't always, on 64-bit hosts. The new version
18552 doesn't catch all possible integer overflows, but it's an
18553 improvement. (Bug#8719)
18555 * alloc.c (make_event_array): Use XINT, not XUINT.
18556 There's no need for unsigned here.
18558 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18559 This follows up to the 2011-05-06 change that substituted uintptr_t
18560 for EMACS_INT. This case wasn't caught back then.
18562 Rework Fformat to avoid integer overflow issues.
18563 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18564 now (part of C89). Include <verify.h>.
18565 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18566 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18567 (Fformat): Avoid the prepass trying to compute sizes; it was only
18568 approximate and thus did not catch overflow reliably. Instead, walk
18569 through the format just once, formatting and computing sizes as we go,
18570 checking for integer overflow at every step, and allocating a larger
18571 buffer as needed. Keep track separately whether the format is
18572 multibyte. Keep only the most-recently calculated precision, rather
18573 than them all. Record whether each argument has been converted to
18574 string. Use EMACS_INT, not int, for byte and char and arg counts.
18575 Support field widths and precisions larger than INT_MAX. Avoid
18576 sprintf's undefined behavior with conversion specifications such as %#d
18577 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18578 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18579 formatting out-of-range floating point numbers with int
18580 formats. (Bug#8668)
18582 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18584 * data.c: Avoid integer truncation in expressions involving floats.
18585 * data.c: Include <intprops.h>.
18586 (arith_driver): When there's an integer overflow in an expression
18587 involving floating point, convert the integers to floating point
18588 so that the resulting value does not suffer from catastrophic
18589 integer truncation. For example, on a 64-bit host (* 4
18590 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18591 Do not rely on undefined behavior after integer overflow.
18593 merge count_size_as_multibyte, parse_str_to_multibyte
18594 * character.c, character.h (count_size_as_multibyte):
18595 Rename from parse_str_to_multibyte; all uses changed.
18596 Check for integer overflow.
18597 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18598 since it's now a duplicate of the other. This is more of
18599 a character than a buffer op, so better that it's in character.c.
18600 * fns.c, print.c: Adjust to above changes.
18602 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18604 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18606 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18608 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18609 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18610 (x_clipboard_manager_save): Now static.
18611 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18613 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18614 (crypto_hash_function): Now static.
18615 Fix pointer signedness problems. Avoid unnecessary initializations.
18617 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18619 * termhooks.h (Vselection_alist): Make it terminal-local.
18621 * terminal.c (create_terminal): Initialize it.
18623 * xselect.c: Support for clipboard managers.
18624 (Vselection_alist): Move to termhooks.h as terminal-local var.
18625 (LOCAL_SELECTION): New macro.
18626 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18627 (symbol_to_x_atom): Remove gratuitous arg.
18628 (x_handle_selection_request, lisp_data_to_selection_data)
18629 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18630 (x_own_selection, x_get_local_selection, x_convert_selection):
18631 New arg, specifying work frame. Use terminal-local Vselection_alist.
18632 (some_frame_on_display): Delete unused function.
18633 (Fx_own_selection_internal, Fx_get_selection_internal)
18634 (Fx_disown_selection_internal, Fx_selection_owner_p)
18635 (Fx_selection_exists_p): New optional frame arg.
18636 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18637 (x_handle_selection_clear): Don't treat other terminals with the
18638 same keyboard specially. Use the terminal-local Vselection_alist.
18639 (x_clear_frame_selections): Use Frun_hook_with_args.
18641 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18643 * xterm.h: Add support for those atoms.
18645 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18647 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18648 (converted_selections, conversion_fail_tag): New global variables.
18649 (x_selection_request_lisp_error): Free the above.
18650 (x_get_local_selection): Remove unnecessary code.
18651 (x_reply_selection_request): Args changed; handle arbitrary array
18652 of converted selections stored in converted_selections.
18653 Separate the XChangeProperty and SelectionNotify steps.
18654 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18655 (x_convert_selection): New function.
18656 (x_handle_selection_event): Simplify.
18657 (x_get_foreign_selection): Don't ignore incoming requests while
18658 waiting for an answer; this will fail when we implement
18659 SAVE_TARGETS, and seems unnecessary anyway.
18660 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18661 (Vx_sent_selection_functions): Doc fix.
18663 2011-05-26 Leo Liu <sdl.web@gmail.com>
18665 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18667 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18669 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18671 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18672 for fringe update if it has periodic bitmap.
18673 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18674 and fringe_bitmap_periodic_p.
18676 * fringe.c (get_fringe_bitmap_data): New function.
18677 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18678 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18679 row. Mark glyph row for fringe update if periodicity changed.
18681 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18682 for fringe update unless it has periodic bitmap.
18684 2011-05-25 Kenichi Handa <handa@m17n.org>
18686 * xdisp.c (get_next_display_element): Set correct it->face_id for
18687 a static composition.
18689 2011-05-24 Leo Liu <sdl.web@gmail.com>
18692 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18694 * fns.c (crypto_hash_function, Fsha1): New function.
18695 (Fmd5): Use crypto_hash_function.
18696 (syms_of_fns): Add Ssha1.
18698 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18700 * gnutls.c: Remove unused macros.
18701 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18702 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18703 Remove macros that are defined and never used.
18704 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18706 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18708 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18709 (Fx_get_selection_internal): Minor cleanup.
18710 (Fx_own_selection_internal): Rename arguments for consistency with
18713 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18715 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18717 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18719 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18721 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18723 * dispnew.c (scrolling_window): Don't exclude the case that the
18724 last enabled row in the desired matrix touches the bottom boundary.
18726 2011-05-21 Glenn Morris <rgm@gnu.org>
18728 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18729 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18730 and add some more files.
18732 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18734 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18735 report_file_error introduced by the change from 2011-05-07.
18737 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18739 * systime.h (Time): Define only if emacs is defined.
18740 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18741 where the include path doesn't have X11/X.h by default. See
18742 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18744 2011-05-20 Kenichi Handa <handa@m17n.org>
18746 * composite.c (find_automatic_composition): Fix previous change.
18748 2011-05-20 Glenn Morris <rgm@gnu.org>
18750 * lisp.mk: New file, split from Makefile.in.
18751 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18752 (shortlisp): Remove.
18753 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18755 2011-05-19 Glenn Morris <rgm@gnu.org>
18757 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18758 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18759 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18760 (lisp): Set the order to that of loadup.el.
18761 (shortlisp): Make it a copy of $lisp.
18762 (SOME_MACHINE_LISP): Remove.
18763 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18764 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18766 2011-05-18 Kenichi Handa <handa@m17n.org>
18768 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18769 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18770 (find_automatic_composition): Mostly rewrite for efficiency.
18772 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18774 * makefile.w32-in: Update dependencies.
18776 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18778 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18779 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18781 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18783 Fix some integer overflow issues, such as string length overflow.
18785 * insdel.c (count_size_as_multibyte): Check for string overflow.
18787 * character.c (lisp_string_width): Check for string overflow.
18788 Use EMACS_INT, not int, for string indexes and lengths; in
18789 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18790 the resulting string length overflows an EMACS_INT; instead,
18791 report a string overflow if no precision given. When checking for
18792 precision exhaustion, use a check that cannot possibly have
18793 integer overflow. (Bug#8675)
18794 * character.h (lisp_string_width): Adjust to new signature.
18796 * alloc.c (string_overflow): New function.
18797 (Fmake_string): Use it. This doesn't change behavior, but saves
18798 a few bytes and will simplify future changes.
18799 * character.c (string_escape_byte8): Likewise.
18800 * lisp.h (string_overflow): New decl.
18802 Fixups, following up to the user-interface timestamp change.
18803 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18804 for UI timestamps, instead of unsigned long.
18805 * msdos.c (mouse_get_pos): Likewise.
18806 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18807 * w32gui.h (Time): Define by including "systime.h" rather than by
18808 declaring it ourselves. (Bug#8664)
18810 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18811 * image.c (clear_image_cache): Likewise.
18813 * term.c (term_mouse_position): Don't assume time_t wraparound.
18815 Be more systematic about user-interface timestamps.
18816 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18817 and sometimes 'EMACS_UINT', to represent these timestamps.
18818 This change causes it to use 'Time' uniformly, as that's what X uses.
18819 This makes the code easier to follow, and makes it easier to catch
18820 integer overflow bugs such as Bug#8664.
18821 * frame.c (Fmouse_position, Fmouse_pixel_position):
18822 Use Time, not unsigned long, for user-interface timestamps.
18823 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18824 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18825 * keyboard.h (last_event_timestamp): Likewise.
18826 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18827 * menu.h (xmenu_show): Likewise.
18828 * term.c (term_mouse_position): Likewise.
18829 * termhooks.h (struct input_event.timestamp): Likewise.
18830 (struct terminal.mouse_position_hook): Likewise.
18831 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18832 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18833 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18834 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18835 what it was before.
18836 * menu.h, termhooks.h: Include "systime.h", for Time.
18838 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18839 Don't assume that the difference between two unsigned long values
18840 can fit into an integer. At this point, we know button_down_time
18841 <= event->timestamp, so the difference must be nonnegative, so
18842 there's no need to cast the result if double-click-time is
18843 nonnegative, as it should be; check that it's nonnegative, just in
18844 case. This bug is triggered when events are more than 2**31 ms
18845 apart (about 25 days). (Bug#8664)
18847 * xselect.c (last_event_timestamp): Remove duplicate decl.
18848 (x_own_selection): Remove needless cast to unsigned long.
18850 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18851 that always fit in int. Use a sentinel instead of a counter, to
18852 avoid a temp and to allay GCC's concerns about possible int overflow.
18853 * frame.h (struct frame): Use int for menu_bar_items_used
18854 instead of EMACS_INT, since it always fits in int.
18856 * menu.c (grow_menu_items): Check for int overflow.
18858 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18860 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18861 Before, the code was not consistent. These values cannot exceed
18862 2**31 - 1 so there's no need to make them unsigned.
18863 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18864 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18865 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18867 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18869 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18870 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18871 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18872 presumably because the widths might not match.
18874 * window.c (size_window): Avoid needless test at loop start.
18876 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18878 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18880 2011-05-12 Drew Adams <drew.adams@oracle.com>
18882 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18884 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18886 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18887 `width' to `bar_area_x' and `bar_area_width', respectively.
18888 (x_scroll_run): Take account of fringe background extension.
18890 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18891 Rename local vars `left' and `width' to `bar_area_x' and
18892 `bar_area_width', respectively.
18893 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18894 background extension.
18896 2011-05-10 Jim Meyering <meyering@redhat.com>
18898 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18900 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18902 * image.c (Finit_image_library): Return t for built-in image types,
18903 like pbm and xbm. (Bug#8640)
18905 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18907 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18909 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18911 * w32console.c (Fset_screen_color): Doc fix.
18912 (Fget_screen_color): New function.
18913 (syms_of_ntterm): Defsubr it.
18915 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18916 unlink the temporary file if Fcall_process didn't create it in the
18918 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18919 child process will be redirected to a file specified with `:file'.
18920 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18921 cue to call_process_cleanup not to close that handle.
18923 2011-05-07 Ben Key <bkey76@gmail.com>
18925 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18926 one of two shell specific rules, either bootstrap-temacs-CMD or
18927 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18928 to the previous implementation of the bootstrap-temacs rule.
18929 The bootstrap-temacs-CMD rule is similar to the previous
18930 implementation of the bootstrap-temacs rule except that it
18931 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18934 These changes, along with some changes to nt/configure.bat,
18935 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18936 earlier fix to add support for --cflags and --ldflags options
18937 that include quotes so that it works whether make uses cmd or
18940 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18942 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18943 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18945 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18946 a string. Handle both cases.
18947 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18948 (Fdbus_register_method): Use Qinvalid_function.
18950 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18952 * makefile.w32-in: Update dependencies.
18953 (LISP_H): Add inttypes.h and stdin.h.
18954 (PROCESS_H): Add unistd.h.
18956 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18958 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18959 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18961 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18963 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18965 * term.c (vfatal): Remove stray call to va_end.
18966 It's not needed and the C Standard doesn't allow it here anyway.
18968 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18969 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18971 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18974 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18976 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18978 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18980 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18982 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18984 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18985 * charset.c (Fdefine_charset_internal): Don't initialize
18986 charset.code_space[15]. The value was garbage, on hosts with
18987 32-bit int (Bug#8600).
18989 * lread.c (read_integer): Be more consistent with string-to-number.
18990 Use string_to_number to do the actual conversion; this avoids
18991 rounding errors and fixes some other screwups. Without this fix,
18992 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18993 (digit_to_number): Move earlier, for benefit of read_integer.
18994 Return -1 if the digit is out of range for the base, -2 if it is
18995 not a digit in any supported base. (Bug#8602)
18997 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18999 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19000 to match comment at start of function. This also removes a
19001 GCC warning about overflow in a 32+64-bit port.
19003 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19005 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19006 Reported by Stefan Monnier in
19007 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19008 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19009 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19011 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19012 (EMACS_UINTPTR): Likewise, with uintptr_t.
19014 * lisp.h: Prefer 64-bit EMACS_INT if available.
19015 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19016 on 32-bit hosts that have 64-bit int, so that they can access
19018 However, temporarily disable this change unless the temporary
19019 symbol WIDE_EMACS_INT is defined.
19021 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19023 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19024 This removes an assumption that EMACS_INT and long are the same
19025 width as pointers. The assumption is true for Emacs porting targets
19026 now, but we want to make other targets possible.
19027 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19028 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19029 In the rest of the code, change types of integers that hold casted
19030 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19031 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19032 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19033 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19034 No need to cast type when ORing.
19035 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19036 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19037 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19038 assume EMACS_INT is the same width as char *.
19039 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19040 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19041 Remove no-longer-needed casts.
19042 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19043 (xg_tool_bar_help_callback, xg_make_tool_item):
19044 Use EMACS_INTPTR to hold an integer
19045 that will be cast to void *; this can avoid a GCC warning
19046 if EMACS_INT is not the same width as void *.
19047 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19048 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19049 (current_message_1, set_message_1):
19050 Use a local to convert to proper width without a cast.
19051 * xmenu.c (dialog_selection_callback): Likewise.
19053 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19054 Also, don't assume VALBITS / RAND_BITS is less than 5,
19055 and don't rely on undefined behavior when shifting a 1 left into
19057 * lisp.h (get_random): Change signature to match.
19059 * lread.c (hash_string): Use size_t, not int, for hash computation.
19060 Normally we prefer signed values; but hashing is special, because
19061 it's better to use unsigned division on hash table sizes so that
19062 the remainder is nonnegative. Also, size_t is the natural width
19063 for hashing into memory. The previous code used 'int', which doesn't
19064 retain enough info to hash well into very large tables.
19065 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19067 * dbusbind.c: Don't possibly lose pointer info when converting.
19068 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19069 Use XPNTR rather than XHASH, so that the high-order bits of
19070 the pointer aren't lost when converting through void *.
19072 * eval.c (Fautoload): Don't double-shift a pointer.
19074 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19076 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19078 * gnutls.c (DEF_GNUTLS_FN):
19079 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19081 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19083 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19086 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19088 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19089 New version that can reserve upto 2GB of heap space.
19091 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19093 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19095 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19097 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19098 `gnutls_certificate_set_x509_key_file'.
19100 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

19157 * process.c: Include lisp.h before w32.h, not after.
19158 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19159 instead of gnutls_record_check_pending.
19161 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19163 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>

19211 rather than `XVECTOR (FOO)->size'.
19213 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19214 inttypes.h, as a gnulib replacement is used if it not available in
19217 2011-04-21 Eli Zaretskii <eliz@gnu.org>

19236 %llo or %llx format is passed. (Bug#8545)
19238 * window.c (window_scroll_line_based): Use a marker instead of
19239 simple variables to record original value of point. (Bug#7952)
19241 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19242 produced by %s or %c overflows available buffer space. (Bug#8545)
19244 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19246 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19247 (SIZE_MAX): Move defn after all includes, as they might #define it.
19249 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19251 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19253 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19255 * keyboard.c (Qdelayed_warnings_hook): Define.
19256 (command_loop_1): Run `delayed-warnings-hook'
19257 if Vdelayed_warnings_list is non-nil.
19258 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19259 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19261 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19263 * doprnt.c (doprnt): Don't return value smaller than the buffer
19264 size if the message was truncated. (Bug#8545).
19266 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19268 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19269 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19271 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19273 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19275 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19277 * makefile.w32-in: Update dependencies.
19279 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19281 Improve `doprnt' and its usage. (Bug#8545)
19282 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19283 `format_end'. Remove support for %l as a conversion specifier.
19284 Don't use xrealloc. Improve diagnostics when the %l size modifier
19285 is used. Update the commentary.
19287 * eval.c (verror): Simplify calculation of size_t.
19289 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19292 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19294 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19297 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19299 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19300 This makes this file independent of the recent pseudovector change.
19302 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19304 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19306 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19307 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19308 Remove unused local.
19309 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19311 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19312 GCC 4.6.0 optimizes based on type-based alias analysis.
19313 For example, if b is of type struct buffer * and v of type struct
19314 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19315 != &v->size, and therefore "v->size = 1; b->size = 2; return
19316 v->size;" must therefore return 1. This assumption is incorrect
19317 for Emacs, since it type-puns struct Lisp_Vector * with many other
19318 types. To fix this problem, this patch adds a new type struct
19319 vectorlike_header that documents the constraints on layout of vectors
19320 and pseudovectors, and helps optimizing compilers not get fooled
19321 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19322 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19323 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19325 (XSETPVECTYPE): Rewrite in terms of new macro.
19326 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19327 This is a bit clearer, and further avoids the possibility of
19328 undesirable aliasing.
19329 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19330 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19331 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19332 since Lisp_Subr is a special case (no "next" field).
19333 (ASIZE): Now uses header.size rather than size.
19334 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19335 to avoid the hassle of writing XVECTOR (foo)->header.size.
19336 (struct vectorlike_header): New type.
19337 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19338 object, to help avoid aliasing.
19339 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19340 (SUBRP): Likewise, since Lisp_Subr is a special case.
19341 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19342 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19343 (struct Lisp_Hash_Table): Combine first two members into a single
19344 struct vectorlike_header member. All uses of "size" and "next" members
19345 changed to be "header.size" and "header.next".
19346 * buffer.h (struct buffer): Likewise.
19347 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19348 * frame.h (struct frame): Likewise.
19349 * process.h (struct Lisp_Process): Likewise.
19350 * termhooks.h (struct terminal): Likewise.
19351 * window.c (struct save_window_data, struct saved_window): Likewise.
19352 * window.h (struct window): Likewise.
19353 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19354 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19355 * buffer.c (init_buffer_once): Likewise.
19356 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19358 * process.c (Fformat_network_address): Use local var for size,
19361 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19363 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19364 * data.c (atof): Remove decl; no longer used or needed.
19365 (digit_to_number): Move to lread.c.
19366 (Fstring_to_number): Use new string_to_number function, to be
19367 consistent with how the Lisp reader treats infinities and NaNs.
19368 Do not assume that floating-point numbers represent EMACS_INT
19369 without losing information; this is not true on most 64-bit hosts.
19370 Avoid double-rounding errors, by insisting on integers when
19371 parsing non-base-10 numbers, as the documentation specifies.
19372 * lisp.h (string_to_number): New decl, replacing ...
19373 (isfloat_string): Remove.
19374 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19375 (read1): Do not accept +. and -. as integers; this
19376 appears to have been a coding error. Similarly, do not accept
19377 strings like +-1e0 as floating point numbers. Do not report
19378 overflow for integer overflows unless the base is not 10 which
19379 means we have no simple and reliable way to continue.
19380 Break out the floating-point parsing into a new
19381 function string_to_number, so that Fstring_to_number parses
19382 floating point numbers consistently with the Lisp reader.
19383 (digit_to_number): Move here from data.c. Make it static inline.
19384 (E_CHAR, EXP_INT): Remove, replacing with ...
19385 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19386 (string_to_number): New function, replacing isfloat_string.
19387 This function checks for valid syntax and produces the resulting
19388 Lisp float number too. Rework it so that string-to-number
19389 no longer mishandles examples like "1.0e+". Use strtoumax,
19390 so that overflow for non-base-10 numbers is reported only when
19391 there's no portable and simple way to convert to floating point.
19393 * textprop.c (set_text_properties_1): Rewrite for clarity,
19394 and to avoid GCC warning about integer overflow.
19396 * intervals.h (struct interval): Use EMACS_INT for members
19397 where EMACS_UINT might cause problems. See
19398 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19399 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19400 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19402 (offset_intervals): Tell GCC not to worry about length overflow
19403 when negating a negative length.
19405 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19406 (overrun_check_free): Likewise.
19408 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19409 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19412 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19413 (gnutls_make_error): Rename local to avoid shadowing.
19414 (gnutls_emacs_global_deinit): ifdef out; not used.
19415 (Fgnutls_boot): Use const for pointer to readonly storage.
19416 Comment out unused local. Fix pointer signedness problems.
19418 * lread.c (openp): Don't stuff size_t into an 'int'.
19419 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19420 about possible signed overflow.
19422 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19423 (GDK_KEY_g): Don't define if already defined.
19424 (xg_prepare_tooltip): Avoid pointer signedness problem.
19425 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19427 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19428 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19430 * xfns.c (Fx_window_property): Simplify a bit,
19431 to make a bit faster and to avoid GCC 4.6.0 warning.
19432 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19434 * fns.c (internal_equal): Don't assume size_t fits in int.
19436 * alloc.c (compact_small_strings): Tighten assertion a little.
19438 Replace pEd with more-general pI, and fix some printf arg casts.
19439 * lisp.h (pI): New macro, generalizing old pEd macro to other
19440 conversion specifiers. For example, use "...%"pI"d..." rather
19441 than "...%"pEd"...".
19442 (pEd): Remove. All uses replaced with similar uses of pI.
19443 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19444 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19445 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19446 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19447 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19448 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19449 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19451 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19452 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19453 * print.c (safe_debug_print, print_object): Likewise.
19454 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19456 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19457 avoiding the 0 flag, which is not portable.
19458 * process.c (Fmake_network_process): Use pI to avoid cast.
19459 * region-cache.c (pp_cache): Likewise.
19460 * xdisp.c (decode_mode_spec): Likewise.
19461 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19462 behavior on 64-bit hosts with printf arg.
19463 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19464 (x_stop_queuing_selection_requests): Likewise.
19465 (x_get_window_property): Don't truncate byte count to an 'int'
19468 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19469 here, since it parses constructs like leading '-' and spaces,
19470 which are not wanted; and it overflows with large numbers.
19471 Instead, simply match F[0-9]+, which is what is wanted anyway.
19473 * alloc.c: Remove unportable assumptions about struct layout.
19474 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19475 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19476 (allocate_vectorlike, make_pure_vector): Use the new macros,
19477 plus offsetof, to remove unportable assumptions about struct layout.
19478 These assumptions hold on all porting targets that I know of, but
19479 they are not guaranteed, they're easy to remove, and removing them
19480 makes further changes easier.
19482 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19483 This doesn't fix a bug but makes the code clearer.
19484 (string_overrun_cookie): Now const. Use initializers that
19485 don't formally overflow signed char, to avoid warnings.
19486 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19487 can cause Emacs to crash when string overrun checking is enabled.
19488 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19489 multiple of sizeof (EMACS_INT); it need not be, if
19490 alignof(EMACS_INT) < sizeof (EMACS_INT).
19491 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19493 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19495 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19497 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19499 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19500 supposed to be handshaking. (Bug#8556)
19501 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19503 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19505 * lisp.h (Qdebug): List symbol.
19506 * eval.c (Qdebug): Restore global linkage.
19507 * keyboard.c (debug-on-event): New variable.
19508 (handle_user_signal): Break into debugger when debug-on-event
19509 matches the current signal symbol.
19511 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19513 * alloc.c (check_sblock, check_string_bytes)
19514 (check_string_free_list): Convert to standard C.
19516 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

20036 However, leave prepare_to_modify_buffer alone. It's never

20074 * xfaces.c (face_at_string_position):
20075 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

20242 * xdisp.c (message_enable_multibyte): Now static.
20244 Declare Lisp_Object Q* variables to be 'static' if not exported.
20245 This makes it easier for human readers (and static analyzers)
20246 to see whether these variables are used from other modules.
20247 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

20260 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20262 Make Emacs functions such as Fatom 'static' by default.
20263 This makes it easier for human readers (and static analyzers)
20264 to see whether these functions can be called from other modules.
20265 DEFUN now defines a static function. To make the function external
20266 so that it can be used in other C modules, use the new macro DEFUE.

20272 Remove decls, since these functions are now static.
20273 (Funintern, Fget_internal_run_time): New decls, since these functions
20274 were already external.
20276 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20284 Mark functions with DEFUE instead of DEFUN,
20285 if they are used in other modules.
20286 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20287 decls for now-static functions.
20288 * buffer.h (Fdelete_overlay): Remove decl.

20324 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20326 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20327 when at ZV. (Bug#8487)
20329 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20331 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20340 (overrun_check_free): Protoize.
20342 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20344 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20345 since callers should never pass a negative size.
20346 Change the signature to match that of plain 'read' and 'write'; see
20347 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20348 * lisp.h: Update prototypes of emacs_write and emacs_read.
20350 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20352 * xdisp.c (redisplay_window): Don't try to determine the character
20353 position of the scroll margin if the window start point w->startp
20354 is outside the buffer's accessible region. (Bug#8468)
20356 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20358 Fix write-region and its subroutines for buffers > 2GB.
20359 * fileio.c (a_write, e_write): Modify declaration of arguments and
20360 local variables to support buffers larger than 2GB.
20361 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20363 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20364 argument, local variables, and return value.
20366 * lisp.h: Update prototypes of emacs_write and emacs_read.
20368 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20370 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20372 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20374 Fix more problems found by GCC 4.6.0's static checks.
20376 * xdisp.c (vmessage): Use a better test for character truncation.
20378 * charset.c (load_charset_map): <, not <=, for optimization,
20379 and to avoid potential problems with integer overflow.
20380 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20381 * casetab.c (set_identity, shuffle): Likewise.
20382 * editfns.c (Fformat): Likewise.
20383 * syntax.c (skip_chars): Likewise.
20385 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20386 This also lets GCC 4.6.0 generate slightly better loop code.
20388 * callint.c (Fcall_interactively): <, not <=, for optimization.
20389 (Fcall_interactively): Count the number of arguments produced,
20390 not the number of arguments given. This is simpler and lets GCC
20391 4.6.0 generate slightly better code.
20393 * ftfont.c: Distingish more carefully between FcChar8 and char.
20394 The previous code passed unsigned char * to a functions like
20395 strlen and xstrcasecmp that expect char *, which does not
20396 conform to the C standard.
20397 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20398 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20399 char * when the C standard requires it.
20401 * keyboard.c (read_char): Remove unused var.
20403 * eval.c: Port to Windows vsnprintf (Bug#8435).
20404 Include <limits.h>.
20405 (SIZE_MAX): Define if the headers do not.
20406 (verror): Do not give up if vsnprintf returns a negative count.
20407 Instead, grow the buffer. This ports to Windows vsnprintf, which
20408 does not conform to C99. Problem reported by Eli Zaretskii.
20409 Also, simplify the allocation scheme, by avoiding the need for
20410 calling realloc, and removing the ALLOCATED variable.
20412 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20414 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20415 But keep the doprint source code for now, as we might revamp it
20416 and use it again (Bug#8435).
20417 * lisp.h (doprnt): Remove.
20418 * Makefile.in (base_obj): Remove doprnt.o.
20419 * deps.mk (doprnt.o): Remove.
20421 error: Print 32- and 64-bit integers portably (Bug#8435).
20422 Without this change, on typical 64-bit hosts error ("...%d...", N)
20423 was used to print both 32- and 64-bit integers N, which relied on
20424 undefined behavior.
20425 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20426 * lisp.h (error, verror): Mark as printf-like functions.
20427 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20428 Report overflow in size calculations when allocating printf buffer.
20429 Do not truncate output string at its first null byte.
20430 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20431 Truncate the output at a character boundary, since vsnprintf does not
20433 * charset.c (check_iso_charset_parameter): Convert internal
20434 character to string before calling 'error', since %c now has the
20436 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20437 overflow when computing char to be passed to 'error'. Do not
20438 pass Lisp_Object to 'error'; pass the integer instead.
20439 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20440 formatted with plain %d.
20442 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20444 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20446 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

20456 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20457 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20458 return ssize_t not "int", and use size_t as the buffer length.
20459 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20460 * gnutls.h: Update declarations.
20461 * process.c (read_process_output): Use ssize_t, to match.
20462 (send_process): Likewise.

20470 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20471 Use unsigned char, to match FcChar8 type definition.
20473 * xterm.c (handle_one_xevent):
20474 * xmenu.c (create_and_show_popup_menu):
20475 * xselect.c (x_decline_selection_request)

20478 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20480 Fix some uses of `int' instead of EMACS_INT.

20488 EMACS_INT. All callers changed.
20489 (pint2hrstr): Last argument is now EMACS_INT.

20505 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20507 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20508 (encode_invocation_designation): Last argument P_NCHARS is now
20510 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.

20534 instead of using internal_with_output_to_temp_buffer.
20535 (Qhelp_form_show): New var.
20536 (syms_of_keyboard): Use DEFSYM macro.
20538 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20574 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20576 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20577 This avoids several warnings with gcc -Wstrict-overflow.
20578 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20579 directly, rather than having caller test rule sign. This avoids
20580 some unnecessary tests.
20581 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20582 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20583 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20585 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20586 (xfont_open): Avoid unnecessary tests.
20588 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20590 * composite.h, composite.c (composition_gstring_put_cache):

20594 breaking out part of COMPOSITION_DECODE_RULE.
20595 (COMPOSITION_DECODE_RULE): Use it.

20597 by using the new macro.
20599 * textprop.c (set_text_properties_1): Change while to do-while,
20600 since the condition is always true at first.
20602 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20603 (interval_deletion_adjustment): Return unsigned value.

20625 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20627 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20628 (font_score): Avoid potential overflow in diff calculation.
20630 * fns.c (substring_both): Remove var that is set but not used.
20631 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20633 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20635 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20636 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20637 can always succeed if overflow has undefined behavior.
20639 * search.c (boyer_moore, wordify): Remove vars set but not used.
20640 (wordify): Omit three unnecessary tests.
20642 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20643 All callers changed. This avoids the need for an unused var.
20645 * casefiddle.c (casify_region): Remove var that is set but not used.
20647 * dired.c (file_name_completion): Remove var that is set but not used.
20649 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20651 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20652 (Finsert_file_contents): Remove unnecessary code checking fd.
20654 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20655 Check for integer overflow on size calculations.
20657 * buffer.c (Fprevious_overlay_change): Remove var that is set
20660 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20661 Remove vars that are set but not used.
20662 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20663 (timer_check_2): Mark vars as initialized.
20665 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20667 * image.c (lookup_image): Remove var that is set but not used.
20668 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20670 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20671 that are set but not used.
20673 * xfns.c (make_invisible_cursor): Don't return garbage
20674 if XCreateBitmapFromData fails (Bug#8410).
20676 * xselect.c (x_get_local_selection, x_handle_property_notify):
20677 Remove vars that are set but not used.
20679 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20680 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20682 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20683 Remove var that is set but not used.
20684 (scroll_bar_windows_size): Now size_t, not int.
20685 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20686 Check for overflow.
20688 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20689 (map_tty_color) [!defined MSDOS]: Likewise.
20691 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20693 * coding.c: Remove vars that are set but not used.

20697 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20698 (decode_coding_charset): Remove vars that are set but not used.
20700 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20701 that is set but not used.
20703 * print.c (print_object): Remove var that is set but not used.
20705 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20706 The gnulib version avoids calling malloc in the usual case,
20707 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20708 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20709 * filelock.c (current_lock_owner): Likewise.
20710 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20711 * sysdep.c: Include allocator.h, careadlinkat.h.
20712 (emacs_no_realloc_allocator): New static constant.
20713 (emacs_readlink): New function.
20714 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20715 ../lib/careadlinkat.h.
20717 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20719 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20720 first non-nil return value).

20734 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20735 and thereabouts. All callers changed.
20736 (get_per_char_metric): Remove parameter `f', unused since
20737 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20739 2011-04-02 Jim Meyering <meyering@redhat.com>
20741 do not dereference NULL upon failed strdup
20742 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20743 (ns_get_family): Likewise.
20745 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20747 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20749 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20751 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

20771 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20773 * keyboard.c (eval_dyn): New fun.
20774 (menu_item_eval_property): Use it.

20778 * fns.c (concat, mapcar1): Accept byte-code-functions.
20780 * eval.c (Fsetq): Handle lexical vars.
20781 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20782 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20783 (FletX, Flet): Obey lexical binding.
20784 (Fcommandp): Handle closures.
20785 (Feval): New `lexical' arg.
20786 (eval_sub): New function extracted from Feval. Use it almost
20787 everywhere where Feval was used. Look up vars in lexical env.
20789 (Ffunctionp): Move from subr.el.
20790 (Ffuncall): Handle closures.
20791 (apply_lambda): Remove `eval_flags'.
20792 (funcall_lambda): Handle closures and new byte-code-functions.
20793 (Fspecial_variable_p): New function.
20794 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20795 but without exporting it to Lisp.
20797 * doc.c (Fdocumentation, store_function_docstring):
20798 * data.c (Finteractive_form): Handle closures.
20800 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20803 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20805 (exec_byte_code): New function extracted from Fbyte_code to handle new
20806 calling convention for byte-code-functions. Add new byte-codes.
20808 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20810 * alloc.c (Fmake_symbol): Init new `declared_special' field.

20819 (try_scrolling): Use it when setting scroll_limit.
20820 Limit scrolling to 100 screen lines.
20821 (redisplay_window): Even when falling back on "recentering",
20822 position point in the window according to scroll-conservatively,
20823 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20825 (try_scrolling): When point is above the window, allow searching
20826 as far as scroll_max, or one screenful, to compute vertical
20827 distance from PT to the scroll margin position. This prevents
20828 try_scrolling from unnecessarily failing when
20829 scroll-conservatively is set to a value slightly larger than the
20830 window height. Clean up the case of PT below the margin at bottom
20831 of window: scroll_max can no longer be INT_MAX. When aggressive
20832 scrolling is in use, don't let point enter the opposite scroll
20833 margin as result of the scroll.
20834 (syms_of_xdisp) <scroll-conservatively>: Document the
20835 threshold of 100 lines for never-recentering scrolling.

20843 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20844 (redisplay_internal): Remove parameter `preserve_echo_area',
20845 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20847 * indent.c (Fvertical_motion):
20848 * window.c (window_scroll_pixel_based, Frecenter):
20849 Don't pass `need_y_p' to `move_it_by_lines'.
20851 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20853 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20854 steal a few bits to be more compact.
20855 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20856 Remove unneeded casts.
20858 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20860 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20862 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20863 binding" message (bug#7967).
20865 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20867 Fix more problems found by GCC 4.6.0's static checks.
20869 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20870 Remove unused local var.
20872 * editfns.c (Fmessage_box): Remove unused local var.
20874 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20875 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20876 Omit unused local vars.
20877 * window.c (shrink_windows): Omit unused local var.
20878 * menu.c (digest_single_submenu): Omit unused local var.
20879 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20880 Omit unused local var.
20882 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20883 Don't assume string length fits in int.
20884 (keyremap_step, read_key_sequence): Use size_t for sizes.
20885 (read_key_sequence): Don't check last_real_key_start redundantly.
20887 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20888 instead of alloca (Bug#8344).
20890 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20891 (Fbacktrace_frame): Don't assume nframes fits in int.
20893 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20895 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20898 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20900 * cm.c (calccost): Turn while-do into do-while, for clarity.
20902 * keyboard.c (syms_of_keyboard): Use the same style as later
20903 in this function when indexing through an array. This also
20904 works around GCC bug 48267.
20906 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20908 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

20911 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20913 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20914 This avoids undefined behavior on integer overflow, and is a bit
20915 more convenient anyway since it is compared to a size_t variable.
20917 Variadic C functions now count arguments with size_t, not int.
20918 This avoids an unnecessary limitation on 64-bit machines, which
20919 caused (substring ...) to crash on large vectors (Bug#8344).
20920 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20921 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20922 All variadic functions and their callers changed accordingly.
20923 (struct gcpro.nvars): Now size_t, not int. All uses changed.
20924 * data.c (arith_driver, float_arith_driver): Likewise.
20925 * editfns.c (general_insert_function): Likewise.

20927 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20928 (funcall_lambda, mark_backtrace): Likewise.
20929 * fns.c (concat): Likewise.
20930 * frame.c (x_set_frame_parameters): Likewise.
20931 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20932 0 if not found, not -1. All callers changed.
20934 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20935 (stack_copy_size): Now size_t, not int.
20936 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20941 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20942 All callers changed.
20944 * lisp.h (multibyte_char_to_unibyte):
20945 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20946 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20947 * character.h (CHAR_TO_BYTE8):
20948 * cmds.c (internal_self_insert):
20949 * editfns.c (general_insert_function):
20950 * keymap.c (push_key_description):
20951 * search.c (Freplace_match):
20952 * xdisp.c (message_dolog, set_message_1): All callers changed.
20954 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20956 * keyboard.c (safe_run_hook_funcall): New function.
20957 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20958 don't set the hook to nil, but remove the offending function instead.
20959 (Qcommand_hook_internal): Remove, unused.
20960 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20961 Vcommand_hook_internal.
20963 * eval.c (enum run_hooks_condition): Remove.
20964 (funcall_nil, funcall_not): New functions.
20965 (run_hook_with_args): Call each function through a `funcall' argument.
20966 Remove `cond' argument, now redundant.
20967 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20968 (Frun_hook_with_args_until_failure): Adjust accordingly.
20969 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

20975 * print.c (strout): Remove parameter `multibyte', unused since
20976 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
20978 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
20979 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20980 All callers changed.
20982 * w32.c (_wsa_errlist): Use braces for struct initializers.
20984 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20985 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20986 All callers changed.
20987 (string_buffer_position): Likewise. Also, make static (it's never
20988 used outside xdisp.c).

20992 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
20993 All callers changed.
20995 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
20997 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21008 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21010 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21030 * w32.c (read_unc_volume): Use parameter `henum', instead of
21031 global variable `wget_enum_handle'.
21033 * keymap.c (describe_vector): Remove parameters `indices' and
21034 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21049 * gtkutil.c (xg_maybe_add_timer):
21050 * keyboard.c (readable_events):
21051 * process.c (wait_reading_process_output):
21052 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21054 * insdel.c (adjust_markers_gap_motion):
21055 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
21056 (gap_left, gap_right): Don't call it.
21058 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

21129 2011-03-23 Julien Danjou <julien@danjou.info>
21131 * term.c (Fsuspend_tty, Fresume_tty):
21132 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
21133 * window.c (temp_output_buffer_show):
21134 * insdel.c (signal_before_change):
21135 * frame.c (Fhandle_switch_frame):
21136 * fileio.c (Fdo_auto_save):
21137 * emacs.c (Fkill_emacs):
21138 * editfns.c (save_excursion_restore):
21139 * cmds.c (internal_self_insert):
21140 * callint.c (Fcall_interactively):
21141 * buffer.c (Fkill_all_local_variables):
21142 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21144 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21145 unconditionally since it does the check itself.
21147 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21149 Fix more problems found by GCC 4.5.2's static checks.
21151 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21152 the first time through the loop, since we know p0 < p1 then.
21153 This also avoids a gcc -Wstrict-overflow warning.
21155 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21156 leading to a memory leak, possible in functions like
21157 load_charset_map_from_file that can allocate an unbounded number
21158 of objects (Bug#8318).
21160 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21161 that could (at least in theory) be that large.
21163 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21164 This is less likely to overflow, and avoids undefined behavior if
21165 overflow does occur. All callers changed. Use strtoul to scan
21166 for the unsigned long integer.
21167 (pint2hrstr): Simplify and tune code slightly.
21168 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21170 * scroll.c (do_scrolling): Work around GCC bug 48228.
21171 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

21176 This also avoids a warning with gcc -Wstrict-overflow.
21178 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21181 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21183 * process.c (Fmake_network_process): Use socklen_t, not int,
21184 where POSIX says socklen_t is required in portable programs.
21185 This fixes a porting bug on hosts like 64-bit HP-UX, where
21186 socklen_t is wider than int (Bug#8277).
21187 (Fmake_network_process, server_accept_connection):
21188 (wait_reading_process_output, read_process_output):
21191 * process.c: Rename or move locals to avoid shadowing.
21192 (list_processes_1, Fmake_network_process):
21193 (read_process_output_error_handler, exec_sentinel_error_handler):
21194 Rename or move locals.
21195 (Fmake_network_process): Define label "retry_connect" only if needed.
21196 (Fnetwork_interface_info): Fix pointer signedness.
21197 (process_send_signal): Add cast to avoid pointer signedness problem.
21198 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
21199 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
21201 Make tparam.h and terminfo.c consistent.
21202 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21203 Include tparam.h instead, since it declares them.
21204 * cm.h (PC): Remove extern decl; tparam.h now does this.
21205 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21206 * terminfo.c: Include tparam.h, to check interfaces.
21207 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21208 (tparam): Adjust signature to match interface in tparam.h;
21209 this removes some undefined behavior. Check that outstring and len
21210 are zero, which they always are with Emacs.
21211 * tparam.h (PC, BC, UP): New extern decls.
21213 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21214 (xftfont_open): Rename locals to avoid shadowing.
21216 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
21217 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
21218 (OTF_TAG_SYM): Omit macro if not needed.
21219 (ftfont_list): Remove unused local.
21220 (get_adstyle_property, ftfont_pattern_entity):
21221 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
21222 Rename locals to avoid shadowing.
21224 * xfont.c (xfont_list_family): Mark var as initialized.
21226 * xml.c (make_dom): Now static.
21228 * composite.c (composition_compute_stop_pos): Rename local to
21230 (composition_reseat_it): Remove unused locals.
21231 (find_automatic_composition, composition_adjust_point): Likewise.
21232 (composition_update_it): Mark var as initialized.
21233 (find_automatic_composition): Mark vars as initialized,
21234 with a FIXME (Bug#8290).
21236 character.h: Rename locals to avoid shadowing.
21237 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21238 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21239 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21240 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21241 to avoid shadowing.
21243 * textprop.c (property_change_between_p): Remove; unused.
21245 * intervals.c (interval_start_pos): Now static.
21247 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
21249 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
21250 Rename locals to avoid shadowing.
21252 * sound.c (wav_play, au_play, Fplay_sound_internal):
21253 Fix pointer signedness.
21254 (alsa_choose_format): Remove unused local var.
21255 (wav_play): Initialize a variable to 0, to prevent undefined
21256 behavior (Bug#8278).
21258 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21260 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21262 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21263 clobbering (Bug#8298).
21264 * sysdep.c (sys_subshell): Likewise.
21265 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21267 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21268 This should get cleaned up, so that child_setup has the
21269 same signature on all platforms.
21271 * callproc.c (call_process_cleanup): Now static.
21272 (relocate_fd): Rename locals to avoid shadowing.
21274 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21276 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21277 not to be necessary, and produces flickering.
21279 2011-03-20 Glenn Morris <rgm@gnu.org>
21281 * config.in: Remove file.
21283 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21297 * xfaces.c (Fx_load_color_file):
21298 Read color file from absolute filename (bug#8250).
21300 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
21302 * makefile.w32-in: Update dependencies.
21304 2011-03-17 Eli Zaretskii <eliz@gnu.org>

21384 * alloc.c (mark_backtrace): Move decl from here ...
21385 * lisp.h: ... to here, so that it can be checked.
21387 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
21388 (Fdefvar): Rewrite so as not to use empty "else".

21393 * callint.c (quotify_arg, quotify_args): Now static.
21394 (Fcall_interactively): Rename locals to avoid shadowing.

21402 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21403 some of which prompt warnings from gcc -Wbad-function-cast.
21404 (Fformat_time_string, Fencode_time, Finsert_char):
21405 (Ftranslate_region_internal, Fformat):

21433 (Fmemory_limit): Cast sbrk's returned value to char *.
21435 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21436 avoids undefined behavior in theory.
21438 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21440 Use functions, not macros, for up- and down-casing (Bug#8254).
21441 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21442 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21443 to use the following functions instead of these macros.
21444 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21445 EMACS_INT, since callers assume the returned value fits in int.
21446 (upcase1): Likewise, for UPCASE_TABLE.
21447 (uppercasep, lowercasep, upcase): New static inline functions.
21448 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21457 which gcc can warn about.
21458 (regex_compile, re_match_2_internal): Mark locals as initialized.
21459 (RETALLOC_IF): Define only if needed.
21460 (WORDCHAR_P): Likewise. This one is never needed, but is used
21461 only in a comment talking about a compiler bug, so put inside
21462 the #if 0 of that comment.
21463 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21464 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21467 * search.c (boyer_moore): Rename locals to avoid shadowing.

21482 Rename locals to avoid shadowing.
21483 (Fvertical_motion): Mark locals as initialized.
21485 * casefiddle.c (casify_object, casify_region): Now static.
21486 (casify_region): Mark local as initialized.

21490 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21491 New macros, so that the caller can use some names other than
21492 gcpro1, gcpro2, etc.
21493 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21495 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21496 argument, for consistency with GCPRO2_VAR, etc: it is now the
21497 prefix of the variable, not the variable itself. All uses
21499 * dired.c (directory_files_internal, file_name_completion):
21500 Rename locals to avoid shadowing.
21502 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21503 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21504 dired.c's scmp function, had undefined behavior.
21505 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21506 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21507 * buffer.h: ... to here, because these macros use current_buffer,
21508 and the new implementation with inline functions needs to have
21509 current_buffer in scope now, rather than later when the macros
21511 (downcase, upcase1): New static inline functions.
21512 (DOWNCASE, UPCASE1): Reimplement using these functions.
21513 This avoids undefined behavior in expressions like
21514 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21515 from race conditions in accessing the global variables
21516 case_temp1 and case_temp2.
21517 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21518 * lisp.h (case_temp1, case_temp2): Remove their decls.
21519 * character.h (ASCII_CHAR_P): Move from here ...
21520 * lisp.h: ... to here, so that the inline functions mentioned
21521 above can use them.
21523 * dired.c (directory_files_internal_unwind): Now static.
21525 * fileio.c (file_name_as_directory, directory_file_name):
21526 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21528 (file_name_as_directory): Use const pointers when appropriate.
21529 (Fexpand_file_name): Likewise. In particular, newdir might
21530 point at constant storage, so make it a const pointer.
21531 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21532 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21534 (Fset_file_times, Finsert_file_contents, auto_save_error):
21535 Rename locals to avoid shadowing.

21539 to avoid shadowing.
21541 * marker.c (bytepos_to_charpos): Remove; unused.
21543 * lisp.h (verify_bytepos, count_markers): New decls,
21544 so that gcc does not warn that these functions aren't declared.
21546 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21547 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21548 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21549 (copy_text): Remove unused local var.
21551 * filelock.c (within_one_second): Now static.
21552 (lock_file_1): Rename local to avoid shadowing.
21554 * buffer.c (fix_overlays_before): Mark locals as initialized.
21555 (fix_start_end_in_overlays): Likewise. This function should be
21556 simplified by using pointers-to-pointers, but that's a different
21558 (switch_to_buffer_1): Now static.
21559 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21560 (report_overlay_modification): Rename locals to avoid shadowing.
21562 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21563 Fix pointer signedness issue.
21564 (sys_subshell): Mark local as volatile if checking for lint,
21565 to suppress a gcc -Wclobbered warning that does not seem to be right.
21566 (MAXPATHLEN): Define only if needed.
21568 * process.c (serial_open, serial_configure): Move decls from here ...
21569 * systty.h: ... to here, so that they can be checked.
21571 * fns.c (get_random, seed_random): Move extern decls from here ...
21572 * lisp.h: ... to here, so that they can be checked.
21574 * sysdep.c (reset_io): Now static.
21575 (wait_for_termination_signal): Remove; unused.
21577 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21578 (copy_keymap_item, append_key, push_text_char_description):
21580 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21581 (DENSE_TABLE_SIZE): Remove; unused.
21582 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21583 (describe_map_tree):
21584 Rename locals to avoid shadowing.
21586 * keyboard.c: Declare functions static if they are not used elsewhere.
21587 (echo_char, echo_dash, cmd_error, top_level_2):
21588 (poll_for_input, handle_async_input): Now static.
21589 (read_char, kbd_buffer_get_event, make_lispy_position):
21590 (make_lispy_event, make_lispy_movement, apply_modifiers):
21591 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
21592 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
21593 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
21594 (read_key_sequence, read_char): Mark locals as initialized.

21671 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
21672 These macros can no longer be used for assignment.

21730 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
21732 Improve quality of tests for time stamp overflow.
21733 For example, without this patch (encode-time 0 0 0 1 1
21734 1152921504606846976) returns the obviously-bogus value (-948597
21735 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
21736 reports time overflow. See
21737 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
21738 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
