1 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
3 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
5 2013-02-15 Eli Zaretskii <eliz@gnu.org>
7 * keyboard.c (read_char): Fix calculation of auto-save time out
8 when auto-save-timeout is less than 4. (Bug#13720)
10 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
11 time. Improve diagnostics in DebPrint.
12 (reader_thread): If cp->char_avail is NULL, set the FILE_AT_EOF
13 flag, so that sys_select could have a chance of noticing that this
14 process is dead, and call a SIGCHLD handler for it. Improve
15 diagnostics in DebPrint.
16 (reap_subprocess): Reset the FILE_AT_EOF flag set by
18 (sys_select): Watch a process whose procinfo.hProcess is non-NULL
19 even if its char_avail is NULL. Allows to reap subprocesses that
20 were forcibly deleted by delete-process. (Bug#13546)
22 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
23 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
24 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
25 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
26 make sure errno is set to an appropriate value. (Bug#13546)
27 (socket_to_fd): Add assertion against indexing fd_info[] with a
28 value that is out of bounds.
29 (sys_accept): If fd is negative, do not set up the child_process
30 structure for reading.
32 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
34 * composite.c (fill_gstring_header): Remove useless prototype.
36 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
37 * print.c (PRINTDECLARE, print_object):
38 * search.c (compile_pattern, fast_looking_at, search_buffer):
39 (simple_search, boyer_moore, Freplace_match):
40 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
41 (get_overlay_arrow_glyph_row, display_mode_element):
42 (decode_mode_spec_coding, message3):
43 * xfaces.c (face_at_string_position): Use bool for booleans.
46 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
48 Fix AIX port (Bug#13650).
49 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
50 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
51 was #undeffed earlier, so it cannot be used as a macro here.
52 Use the constant and not the macro.
54 2013-02-15 Eli Zaretskii <eliz@gnu.org>
56 * w32proc.c (new_child): If no vacant slots are found in
57 child_procs[], make another pass looking for slots whose process
58 has exited or died. (Bug#13546)
60 * w32.c (sys_pipe): When failing due to file descriptors above
61 MAXDESC, set errno to EMFILE.
62 (_sys_read_ahead): Update cp->status when failing to read serial
63 communications input, so that the status doesn't stay at
64 STATUS_READ_IN_PROGRESS. (Bug#13546)
66 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
68 * gtkutil.c (tb_size_cb): New function.
69 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
71 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
73 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
76 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
78 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
80 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
82 * font.c (font_range): Add pos_byte argument. Adjust comment
84 * font.h (font_range): Adjust prototype.
85 * composite.c (autocmp_chars): Pass byte position to font_range.
86 Break long line. Remove useless prototype and format comment.
88 2013-02-13 Glenn Morris <rgm@gnu.org>
90 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
92 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
94 Improve AIX port some more (Bug#13650).
95 With this, it should be as good as it was in 23.3, though it's
96 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
97 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
98 * unexaix.c (start_of_text): Remove.
99 (_data, _text): Declare as char[], not int, as AIX manual suggests.
100 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
101 (orig_load_scnptr, orig_data_scnptr):
102 Now off_t, not long, since they are file offsets.
103 (make_hdr): Use _data, not start_of_data ().
104 This is the key part of the fix.
105 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
106 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
108 * pre-crt0.c (data_start): Initialize to 1.
109 This ports to compilers that optimize the external declaration
110 'int x = 0;' as if it were 'int x;' to shrink the executable.
112 Improve AIX port (Bug#13650).
113 This doesn't fix the bug, but it makes progress: Emacs builds now.
114 * unexaix.c: Include inttypes.h, stdarg.h.
115 (report_error, report_error_1): Mark as _Noreturn.
116 (report_error): Don't report the wrong errno.
117 (report_error_1): Now varargs. All callers changed.
118 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
119 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
120 (write_ptr): Use %p to print address rather than %lx and a cast
121 to unsigned long. Grow buffer a bit, to be safer.
123 2013-02-13 Eli Zaretskii <eliz@gnu.org>
125 * bidi.c (bidi_resolve_neutral): After finding the next
126 non-neutral character, accept NEUTRAL_ON type as well, because
127 directional control characters, such as LRE and RLE, have their
128 type converted to that by bidi_resolve_weak. This avoids aborts
129 when LRE/RLE follows a run of neutrals.
130 (bidi_move_to_visually_next): Assert that return value of
131 bidi_peek_at_next_level is non-negative. Negative values will
134 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
136 Minor getenv-related fixes.
137 * callproc.c (Fcall_process_region) [!DOS_NT]:
138 Avoid unnecessary duplicate call to getenv.
139 * callproc.c (init_callproc):
140 * dispnew.c (init_display):
141 * sysdep.c (sys_subshell):
142 Omit unnecessary cast of getenv or egetenv.
144 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
146 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
149 2013-02-12 Eli Zaretskii <eliz@gnu.org>
151 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
153 (display_line): Set w->region_showing to the value of
154 it->region_beg_charpos, not to -1. This fixes redisplay
155 optimization when cursor is moved up after M->. (Bug#13623)
157 (try_scrolling): Scroll text up more if point is too close to ZV
158 and inside the scroll margin. This makes sure point is moved
159 outside the scroll margin in these cases.
161 * window.h (struct window): region_showing can no longer be
164 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
166 Tune by using memchr and memrchr.
167 * doc.c (Fsnarf_documentation):
168 * fileio.c (Fsubstitute_in_file_name):
169 * search.c (find_newline, scan_newline):
170 * xdisp.c (pos_visible_p, display_count_lines):
171 Use memchr and memrchr rather than scanning byte-by-byte.
172 * search.c (find_newline): Rename from scan_buffer.
173 Omit first arg TARGET, as it's always '\n'. All callers changed.
175 Clean up read_key_sequence a tiny bit more.
176 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
177 (read_key_sequence): Remove unused locals.
179 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
181 Clean up read_key_sequence a bit; reread active keymaps after first event.
182 * keyboard.c (read_char, read_char_x_menu_prompt)
183 (read_char_minibuf_menu_prompt):
184 Replace nmaps+maps with a single `map' arg.
185 (follow_key): Operate on a single map.
186 (active_maps): New function.
187 (test_undefined): Also return true for nil bindings.
188 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
189 a single (composed) keymap. Remember `first_event' to choose the right
190 set of active keymaps. Recompute the set of keymaps after receiving
191 the first event. Remove GOBBLE_FIRST_EVENT.
192 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
193 * keyboard.h (read_char): Update declaration.
194 * lread.c (read_filtered_event): Adjust call to read_char.
196 2013-02-11 Eli Zaretskii <eliz@gnu.org>
198 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
199 Don't use the limitation on backwards movement when lines are truncated
200 in the window. (Bug#13675)
202 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
204 * marker.c (set_marker_internal): If desired position is passed
205 as a marker, avoid call to buf_charpos_to_bytepos.
206 * window.c (Fset_window_point): Omit redundant type checking.
207 (Fset_window_start): Likewise. Format comment.
208 (window_scroll_pixel_based): Use set_marker_restricted_both
209 with character and byte positions obtained from an iterator.
210 (Fset_window_configuration): Use set_marker_restricted_both.
211 * xdisp.c (message_dolog): Likewise.
213 2013-02-10 Eli Zaretskii <eliz@gnu.org>
215 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
216 When text lines are longer than window's screen lines, don't move back
217 too far. This speeds up some redisplay operations. (Bug#13675)
219 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
221 * syntax.c (scan_sexps_forward): Fix byte position calculation
222 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
224 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
226 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
229 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
231 Minor hashing refactoring.
232 * fns.c (SXHASH_REDUCE): Move to lisp.h.
233 (sxhash_float): Return EMACS_UINT, for consistency with the other
235 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
236 non-static inline function and therefore can't use static vars.
237 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
238 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
239 with the other hash functions.
241 2013-02-09 Eli Zaretskii <eliz@gnu.org>
243 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
244 XXXXXX part of the temporary file pattern is not downcased even
245 when w32-downcase-file-names is non-nil. (Bug#13661)
247 * xdisp.c (decode_mode_spec): Remove handling of %t.
249 * msdos.c (careadlinkatcwd): Remove.
251 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
253 * lread.c (skip_dyn_bytes): New function (bug#12598).
254 (read1): Use it. Use getc instead of READCHAR to read bytes.
255 (load_each_byte): Remove. Update users.
257 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
259 * search.c (scan_buffer): Calculate end byte position just once.
260 (scan_newline): Do not recalculate start_byte.
261 (search_command): Use eassert.
262 * syntax.c (struct lisp_parse_state): New member location_byte.
263 (scan_sexps_forward): Record from_byte and avoid redundant
264 character to byte position calculation ...
265 (Fparse_partial_sexp): ... here. Break too long line.
267 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
269 * lisp.h (make_uninit_vector): New function.
270 * alloc.c (Fvector, Fmake_byte_code):
271 * ccl.c (Fregister_ccl_program):
272 * charset.c (Fdefine_charset_internal, define_charset_internal):
273 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
274 * composite.c (syms_of_composite):
275 * font.c (Fquery_font, Ffont_info, syms_of_font):
276 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
277 * ftfont.c (ftfont_shape_by_flt):
278 * indent.c (recompute_width_table):
279 * nsselect.m (clean_local_selection_data):
280 * syntax.c (init_syntax_once):
281 * w32unsubscribe.c (uniscribe_shape):
282 * window.c (Fcurrent_window_configuration):
283 * xfaces.c (Fx_family_fonts):
284 * xselect.c (selection_data_to_lisp_data): Use it.
286 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
288 * coding.c (Fdefine_coding_system_internal): Use AREF where
289 argument is known to be a vector.
290 * fns.c (Flocale_info): Likewise for ASET.
291 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
292 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
294 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
296 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
299 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
300 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
301 updateCollectionBehaviour.
303 * nsterm.m (NEW_STYLE_FS): Remove.
304 (ns_last_use_native_fullscreen): New variable.
305 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
306 (x_set_window_size): Do not take title bar and tool bar into account
307 if isFullscreen returns YES.
308 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
309 (check_native_fs): New function.
310 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
311 (ns_term_init): Remove NEW_STYLE_FS.
312 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
313 and tool bar if isFullscreen returns NO.
314 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
315 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
317 (window:willUseFullScreenPresentationOptions:): New method.
318 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
319 Hide toolbar if not enabled (Bug#13444).
320 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
321 Restore tool bar if enabled, hide it otherwise (Bug#13444).
322 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
323 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
324 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
325 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
326 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
327 (syms_of_nsterm): Add ns-use-native-fullscreen.
329 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
331 * fileio.c (Qchoose_write_coding_system): Now static.
333 2013-02-04 Eli Zaretskii <eliz@gnu.org>
335 * xdisp.c (window_buffer_changed): region_showing can be negative,
336 which still means region is being displayed.
337 (redisplay_internal): Resurrect code that forced redisplay of the
338 whole window when showing region and the mark has changed.
339 Record the new mark position to allow redisplay optimizations.
340 (display_line): If it->region_beg_charpos is non-zero, set the
341 window's region_showing member to -1. (Bug#13623) (Bug#13626)
343 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
344 not bitfield of 1 bit.
346 2013-02-03 Daniel Colascione <dancol@dancol.org>
348 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
349 daemon mode works on cygw32 when Emacs is installed and not just
352 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
354 Avoid file time stamp bug on MS-Windows (Bug#13149).
355 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
356 as FAT32 doesn't update time stamps when truncating them.
357 Also, check that a file time stamp is not a multiple of 100 ns;
358 this should catch all instances of the problem on MS-Windows,
359 as its native file system resolution is 100 ns or worse, and
360 checking for a non-multiple of 100 ns should impose only a small
361 overhead on systems with ns resolution.
363 2013-02-02 Eli Zaretskii <eliz@gnu.org>
365 Avoid encoding file names on MS-Windows when they need to be run
366 through dostounix_filename.
367 * w32.c (normalize_filename): Accept an additional argument
368 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
369 downcase it even if w32-downcase-file-names is non-nil.
370 (dostounix_filename): Accept an additional argument MULTIBYTE and
371 pass it to normalize_filename.
372 (emacs_root_dir): Adjust.
374 * msdos.h (dostounix_filename): Adjust prototype.
376 * w32.h (dostounix_filename): Adjust prototype.
378 * msdos.c (dostounix_filename): Accept an additional argument and
380 (init_environment): Adjust callers of dostounix_filename.
382 * fileio.c (Ffile_name_directory, file_name_as_directory)
383 (directory_file_name, Fexpand_file_name)
384 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
386 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
388 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
389 variables, as egetenv is case-insensitive for DOS_NT.
391 * dired.c (file_name_completion): Don't call Fdirectory_file_name
392 with an encoded file name.
394 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
395 Adjust calls to dostounix_filename.
397 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
399 * unexw32.c (unexec): Adjust call to dostounix_filename.
401 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
403 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
406 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
409 * callproc.c (Fcall_process): Make sure program name in PATH and
410 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
411 is passed to exec/spawnve, which fails unless the file-name
414 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
415 even if w32-quote-process-args is nil.
417 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
419 Fix timestamp bug when write-region appends nothing (Bug#13149).
420 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
421 the file's time stamp doesn't change if Emacs happens to write nothing
422 to the file, and on a buggy file system this could cause Emacs to
423 incorrectly infer that the file system doesn't have the bug.
424 Avoid this problem by inhibiting the inference in this case.
426 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
428 * window.h (struct window): Convert base_line_number, base_line_pos
429 and column_number_displayed members from Lisp_Object to ptrdiff_t.
430 Convert region_showing member from Lisp_Object to bitfield.
431 Remove sequence_number member. Adjust comments.
432 * window.c (sequence_number): Remove.
433 (make_window): Initialize column_number_displayed.
434 * print.c (print_object): Follow the printed representation of
435 frames and print window pointer to distinguish between windows.
436 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
437 * xdisp.c (wset_base_line_number, wset_base_line_pos)
438 (wset_column_number_displayed, wset_region_showing): Remove.
439 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
440 (try_scrolling, try_cursor_movement, redisplay_window)
441 (try_window_reusing_current_matrix, try_window_id, display_line)
442 (display_mode_lines, decode_mode_spec): Adjust users.
443 * .gdbinit (pwinx): Do not print sequence_number.
445 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
447 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
448 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
449 * dired.c: Include <fcntl.h>.
450 (open_directory): New function, which uses open and fdopendir
451 rather than opendir. DOS_NT platforms still use opendir, though.
452 (directory_files_internal, file_name_completion): Use it.
453 (file_attributes): New function, with most of the old Ffile_attributes.
454 (directory_files_internal, Ffile_attributes): Use it.
455 (file_attributes, file_name_completion_stat): First arg is now fd,
456 not dir name. All uses changed. Use fstatat rather than lstat +
458 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
459 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
460 (emacs_readlinkat): New function, with much of the old
461 Ffile_symlink_p, but with an fd argument for speed.
462 It uses readlinkat rather than careadlinkatcwd, so that it
463 need not assume the working directory.
464 (Ffile_symlink_p): Use it.
465 * filelock.c (current_lock_owner): Use emacs_readlinkat
466 rather than emacs_readlink.
467 * lisp.h (emacs_readlinkat): New decl.
468 (READLINK_BUFSIZE, emacs_readlink): Remove.
469 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
470 (emacs_norealloc_allocator, emacs_readlink): Remove.
471 This stuff is moved to fileio.c.
472 * w32.c (fstatat, readlinkat): New functions.
473 (careadlinkat): Don't check that fd == AT_FDCWD.
474 (careadlinkatcwd): Remove; no longer needed.
476 2013-01-31 Glenn Morris <rgm@gnu.org>

479 (Fwrite_region): Update for new choose_write_coding_system args.
480 Move the last piece of choose_write_coding_system here. (Bug#13522)
481 (syms_of_fileio): Add choose-write-coding-system.
483 2013-01-30 Eli Zaretskii <eliz@gnu.org>
485 * w32.c (sys_open): Zero out the flags for the new file descriptor.
486 (sys_close): Zero out the flags for the file descriptor before
487 closing it. (Bug#13546)
489 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
490 (logon_network_drive, stat_worker, symlink, chase_symlinks):
491 Use CharNextExA and CharPrevExA to iterate over file names encoded in
494 * w32.c (w32_get_long_filename, init_environment, readlink):
495 Support file names encoded in DBCS codepages.
496 (readlink): Use the current file-name-coding-system, not the ANSI
497 codepage, to decode and handle targets of symlinks.
499 2013-01-28 Eli Zaretskii <eliz@gnu.org>
501 * w32.c (opendir): Now accepts a 'const char *'.
503 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
505 Remove obsolete redisplay code. See the discussion at
506 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
507 * dispnew.c (preemption_period, preemption_next_check): Remove.
508 (Vredisplay_preemption_period): Likewise.
509 (update_frame, update_single_window, update_window, update_frame_1):
510 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
511 used, following the 2012-06-22 change.
513 2013-01-25 Eli Zaretskii <eliz@gnu.org>
515 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
517 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

527 * w32.c (max_filename_mbslen): New function.
528 (normalize_filename, readdir): Use it to detect locales where ANSI
529 encoding of file names uses a double-byte character set (DBCS).
530 If a DBCS encoding is used, advance by characters using
531 CharNextExA, instead of incrementing a 'char *' pointer.
532 Use _mbslwr instead of _strlwr. (Bug#13515)
534 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
535 request of memory reservation to 1.7GB. (Bug#13065)
537 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
539 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
540 at check_extra_latin label. (Bug#13505)
542 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
544 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
545 Avoid redundant calls to strlen.
547 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
549 Drop async_visible and async_iconified fields of struct frame.
550 This is possible because async input is gone; for details, see
551 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
552 * frame.h (struct frame): Remove async_visible and async_iconified
553 members, convert garbaged to unsigned bitfield. Adjust comments.
554 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
555 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
556 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
557 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
558 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
560 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
561 properly. Likewise for obscured.
563 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
566 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
568 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
570 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
571 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
573 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
575 * xdisp.c (message2, message2_nolog): Remove functions.
576 (message3, message3_nolog): Extract nbytes and multibyteness directly
577 from the string. Change all callers.
578 (message3_nolog): Don't set message_enable_multibyte since set_message
579 will reset it anyway.
580 (message1, message1_nolog): Use message3.
581 (vmessage): Use a stack allocated buffer rather than f->message_buf.
582 (with_echo_area_buffer): Remove last two arguments. Update all callers.
583 (set_message): Drop all but the second arg, which has to be a string.
584 (set_message_1): Simplify now that we know that a1 is NULL and the
585 second arg is a string.
586 * frame.h (struct frame): Remove `message_buf' field.
587 Use glyphs_initialized_p instead.
588 (FRAME_MESSAGE_BUF): Remove macro.
589 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
590 * lisp.h (message2, message2_nolog): Remove declarations.
591 (message3, message3_nolog): Update declarations.
592 * keyboard.c (read_char_minibuf_menu_text)
593 (read_char_minibuf_menu_width): Remove vars.
594 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
595 to correctly handle multibyte strings.
596 * frame.c (delete_frame): Don't free message_buf any more.
597 * editfns.c (message_text, message_length): Remove vars.
598 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
599 * fileio.c (auto_save_error): Use message3 instead of message2.
600 * dispnew.c (adjust_frame_message_buffer): Remove function.
602 2013-01-23 Eli Zaretskii <eliz@gnu.org>
604 * w32term.c (w32fullscreen_hook): Account correctly for the screen
605 real estate used for the tool bar and the menu bar.
607 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
609 * insdel.c (prepare_to_modify_buffer): Force redisplay if
610 hidden buffer is prepared to modification (Bug#13164).
612 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
614 * window.h (struct window): Change window_end_valid member from
615 Lisp_Object to a bitfield. Adjust comments.
616 (wset_window_end_valid): Remove.
617 * window.c (adjust_window_count): Clear window_end_valid.
618 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
619 (Fwindow_line_height, set_window_buffer, Frecenter)
620 (Fsplit_window_internal, Fdelete_other_windows_internal)
621 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
622 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
623 * xdisp.c (check_window_end, reconsider_clip_changes)
624 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
625 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
626 (find_first_unchanged_at_end_row, try_window_id): Likewise.
628 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
630 * xdisp.c (mark_window_display_accurate): Simplify the loop
631 assuming that the only one of vchild, hchild or buffer window
632 slots is non-nil. Call mark_window_display_accurate_1 for
633 the leaf windows only.
634 (mark_window_display_accurate_1): Always assume leaf window.
637 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
639 * emacs.c (Qkill_emacs_hook): Now static.
641 * fileio.c (Finsert_file_contents): Simplify.
642 Remove unnecessary assignments and tests.
644 2013-01-21 Eli Zaretskii <eliz@gnu.org>
646 * w32.c (acl_set_file): Don't test for errors unless
647 set_file_security returns FALSE. Avoids spurious errors when
650 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
652 * fileio.c (Finsert_file_contents): Revert code introduced at
653 2013-01-18 in favor of the simpler and generally better fix.
654 Save stack space by removing 'buffer' and reusing 'read_buf'
657 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
659 * lisp.h (eabs): Define unconditionally (Bug#13419).
660 The old "#if !defined (eabs)" was an unnecessary revenant of back
661 when this macro was called "abs". Document 'eabs' better.
663 2013-01-19 Glenn Morris <rgm@gnu.org>
665 * fns.c (Frandom): Doc fix.
667 2013-01-19 Eli Zaretskii <eliz@gnu.org>
669 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
670 segfault when there are lots of overlays.
672 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
673 when there are lots of overlays.
674 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
675 for the details and a way to reproduce.
677 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
679 * fileio.c: Use O_APPEND to append.
680 This corresponds better to the natural interpretation of "append",
681 and avoids the need to open the output file twice, or to invoke
682 lseek when APPEND is neither nil nor a number.
683 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
684 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
685 file possibly twice, and lseeking to its end; this avoids the
686 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
687 at the same time: the combination is never needed and apparently
688 it doesn't work with DOS_NT.
690 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
691 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
693 Allow floating-point file offsets.
694 Problem reported by Vitalie Spinu in
695 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
696 * fileio.c (emacs_lseek): Remove.
697 (file_offset): New function.
698 (Finsert_file_contents, Fwrite_region): Use it.
700 2013-01-19 Chong Yidong <cyd@gnu.org>
702 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
703 aborting on Fsignal (Bug#13289).
705 2013-01-19 Eli Zaretskii <eliz@gnu.org>
707 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
708 set_file_security as failure due to insufficient privileges.
709 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
710 (fstat): Return owner and group like 'stat' and 'lstat' do.
712 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
714 Work around bug in CIFS and vboxsf file systems (Bug#13149).
715 The bug was observed on Ubuntu operating inside a virtual machine,
716 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
717 The workaround introduces a race condition on non-buggy hosts,
718 but it's an unlikely race and anyway there's a nearly identical
719 nearby race that can't be fixed.
720 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
722 (Fwrite_region): Test for file system time stamp bug.
723 (init_fileio): New function.
724 * lisp.h (init_fileio): Declare it.
725 * emacs.c (main): Call it.
727 * fileio.c (Finsert_file_contents): Simplify new diagnostic
728 and make it more consistent with other stat-failure diagnostics.
730 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
732 Fix crash when inserting data from non-regular files.
733 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
734 for the error description produced by valgrind.
735 * fileio.c (read_non_regular): Rename to read_contents.
736 Free Lisp_Save_Value object used to pass parameters.
737 (read_non_regular_quit): Rename to read_contents_quit.
738 (Finsert_file_contents): Redesign internal file reading loop to adjust
739 gap and end positions after each read and so help make_gap to work
740 properly. Do not signal an I/O error too early and so do not leave
741 not yet decoded characters in a buffer, which was the reason of
742 redisplay crash. Use list2 to build return value. Adjust comments.
744 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
746 Close a race when statting and reading files (Bug#13149).
747 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
748 This avoids a race if the file is renamed between stat and open.
749 This race is not the problem originally noted in Bug#13149;
750 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
752 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

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

782 (map_keymap_char_table_item): Adjust accordingly.
783 * fileio.c (non_regular_fd, non_regular_inserted)
784 (non_regular_nbytes): Remove.
785 (Finsert_file_contents): Convert trytry to ptrdiff_t.
786 Use format_save_value to pass parameters to read_non_regular.
787 (read_non_regular): Use XSAVE_ macros to extract parameters.
789 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
791 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
793 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
795 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
796 extraction from any Lisp_Save_Value slot. Add type checking.
797 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
798 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
799 * xselect.c: All users changed.
801 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
803 Some convenient bits to deal with Lisp_Save_Values.
804 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
805 (allocate_misc): Remove prototype.
806 (format_save_value): New prototype.

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

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

866 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
868 Fix SIGDANGER handlers, for AIX (Bug#13408).
869 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
870 Move handlers here from emacs.c; they were out of place.
872 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
874 * xterm.c (syms_of_xterm): Adjust documentation for
875 scroll-bar-adjust-thumb-portion.
877 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
879 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
880 determine whether scroll bar thumb size should be adjusted or
881 not. Use variable for MOTIF.
883 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
886 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

895 (nsfont_open): Move block_input earlier. Add unblock_input before early
897 (nsfont_draw): Add block/unblock_input calls.
899 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
901 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
902 for old_charpos and old_bytepos.
904 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>

907 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
908 Clear tzvalbuf_in_environ if this workaround is in effect.
909 Problem and fix reported by Kazuhiro Ito.
911 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
913 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):
914 Fix ambiguous doc string cross-reference(s).
916 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
917 doc string cross-reference(s).
919 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
920 string cross-reference(s).
922 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
924 Avoid unnecessary byte position calculation for the gap movement.
925 Since all users of move_gap do CHAR_TO_BYTE for other purposes
926 anyway, all of them should use move_gap_both instead.
927 * lisp.h (move_gap): Remove prototype.
928 * insdel.c (move_gap): Remove.
929 (move_gap_both): Add eassert.
930 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
931 * xml.c (parse_region): Likewise.
933 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
935 emacsclient -t should not suspend Emacs server (Bug#13387)
936 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
938 * term.c (init_tty): Use them instead of rolling our own code.
939 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
940 switches from 'signal' to 'pthread_sigmask', which is safer in
941 multithreaded applications.
942 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
943 which has already arranged for that.
944 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

1027 * w32term.c (w32_draw_underwave):
1028 * xterm.c (x_draw_underwave): Make underwave look more triangular

1031 * nsterm.m (ns_draw_text_decoration):
1032 * w32term.c (x_draw_glyph_string):
1033 * xterm.c (x_draw_glyph_string): Don't use previous underline

1062 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1063 for the bug this caused.
1065 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1067 * coding.c (Qmac): Now static.
1069 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>

1089 (xg_update_submenu): Skip tearoff only if
1090 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1091 (xg_initialize): Initialize xg_detached_menus only if
1092 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1094 * xterm.h (struct x_output): Surround handlebox_widget with
1095 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

1121 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1123 Port EXTERNALLY_VISIBLE to Clang 3.2.
1124 * conf_post.h (__has_attribute): New macro.
1125 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1127 2012-12-27 Glenn Morris <rgm@gnu.org>
1129 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1130 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1132 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1134 * fileio.c (file_name_as_directory, directory_file_name):
1135 Accept an additional argument MULTIBYTE to indicate whether the input C
1136 came from a multibyte or a unibyte Lisp string; all callers
1137 adjusted. Don't assume the input string is always multibyte.
1139 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1140 don't ENCODE_FILE them, and return a unibyte string if the input
1142 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1143 don't assume the input strings will always be multibyte. If the
1144 input strings are multibyte, decode strings obtained from C
1147 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1149 * lisp.h (toplevel): Add two notices to the comment about

1158 * keyboard.c (record_asynch_buffer_change): Initialize an event
1159 only if it's really needed.
1160 * frame.h (enum output_method): Remove output_mac member since
1161 it's a leftover from the deleted code.
1162 * frame.c (Fframep): Adjust user here ...
1163 * terminal.c (Fterminal_live_p): ... and here.
1164 * coding.c (Qmac): Now here because it's only used to denote
1165 end-of-line encoding type.
1166 (syms_of_coding): DEFSYM it.
1167 * frame.h (Qmac): Remove duplicated declaration.
1169 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1171 * window.c (select_window_1): Now static, since it's used only here.

1175 * window.c (window_body_cols): Subtract display margins from the
1176 window body width on TTYs as well. See
1177 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1178 for the original report.
1180 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1182 * xdisp.c (redisplay_window): Remove inner local variable
1183 because the outer shadowed one has the same meaning.
1184 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1186 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1187 (xg_create_tool_bar): Adjust users.
1189 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1191 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1192 * buffer.c (Fget_buffer_create): Use it to set compact field of
1193 struct buffer_text to avoid accessing an uninitialized value
1194 when compact_buffer is called for the first time.
1195 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1196 (Fset_buffer_modified_p): Use buffer_window_count to check
1197 whether the buffer is displayed in some window.
1198 * xdisp.c (message_dolog): Likewise.
1200 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1202 * w32.c (acl_set_file): If setting the file security descriptor
1203 fails, and the new DACL is identical to the existing one, silently
1204 return success. This fixes problems for users backing up their
1205 own files without having the necessary privileges for setting
1206 security descriptors.
1208 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1210 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1211 after WaitForSingleObject returns normally. This expedites reader
1212 thread shutdown when delete_child triggers it.
1213 (reap_subprocess): More accurate commentary for why we call
1214 delete_child only when cp->fd is negative.
1216 * w32.c (sys_close): Do not call delete_child on a subprocess
1217 whose handle is not yet closed. Instead, set its file descriptor
1218 to a negative value, so that reap_subprocess will call
1219 delete_child on that subprocess when its SIGCHLD arrives.
1220 This avoids closing handles used for communications between sys_select
1221 and reader_thread, which doesn't give sys_select a chance to
1222 notice that the process exited and invoke the SIGCHLD handler for
1225 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1227 * nsfns.m (Fns_do_applescript): Run event loop until script has
1228 been executed (Bug#12969).
1229 (ns_run_ascript): Chech as_script for nil, set to nil after
1232 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1234 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1236 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1238 * w32term.c (w32fullscreen_hook): New function.
1239 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1241 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1243 * fileio.c (Finsert_file_contents): Doc fix.
1245 * w32proc.c (new_child, delete_child, find_child_pid): For a
1246 subprocess, consider its slot being in use as long as its process
1247 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1248 slot when a new process is started immediately after killing
1249 another one, without waiting enough time for the first process to
1250 be reaped and resources allocated for it be orderly freed.
1252 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1254 2012-12-21 Chong Yidong <cyd@gnu.org>
1256 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1258 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1260 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1262 * w32.c (get_name_and_id): Always pass NULL as the first argument
1263 of lookup_account_sid. Avoids crashes with UNC file names that
1264 refer to DFS domains, not to specific machine names. (Bug#12621)
1265 Remove now unused argument FNAME; all callers changed.
1266 (get_file_owner_and_group): Remove now unused argument FNAME; all
1269 2012-12-21 Chong Yidong <cyd@gnu.org>
1271 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1272 error for invalid chars, don't check for a nil return value.
1274 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1276 Avoid calls to CHAR_TO_BYTE if byte position is known.
1277 * editfns.c (make_buffer_string_both): Use move_gap_both.
1278 (Fbuffer_string): Use make_buffer_string_both.

1281 (buf_bytepos_to_charpos): Likewise.
1282 (charpos_to_bytepos): Remove.
1283 * fileio.c (Finsert_file_contents): Use move_gap_both.
1284 * search.c (Freplace_match): Likewise.
1285 * process.c (process_send_region): Likewise. Use convenient
1286 names for byte positions.
1287 * lisp.h (charpos_to_bytepos): Remove prototype.
1288 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1289 * insdel.c (move_gap): Likewise.

1295 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1297 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1298 (redisplay_internal): Don't bother selecting the frame to get the
1299 proper value of frame-local variables (bug#13225).
1301 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1303 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1304 Rename 4th argument since it may be buffer or string. Adjust comment.
1305 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1307 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1309 * coding.c (Fdetect_coding_region): Do not check start and end with
1310 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1311 (code_convert_region): Likewise.
1313 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1315 * w32.c (acl_get_file, acl_set_file): Run the file name through
1316 map_w32_filename, and resolve any symlinks in the file name, like
1318 (acl_set_file): Call revert_to_self, if any privileges were
1321 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1323 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1324 ($(BLD)/w32.$(O)): Update dependencies.
1326 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1328 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1329 propagate redisplay's scrolling (if any) to the right window.
1330 (redisplay_internal): Use ensure_selected_frame.
1331 (display_mode_lines): Complete last fix.
1332 * window.c (select_window_1): New func, extracted from select_window.
1333 (select_window): Use it.
1334 * window.h (select_window_1): Declare.
1336 2012-12-17 Eli Zaretskii <eliz@gnu.org>

1360 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1362 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1363 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1364 for some of that bug's symptoms can now cause Emacs to abort.
1365 Remove the workaround.
1366 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1367 The bug that caused SIGCHLD to get lost has been fixed, and the
1368 workaround for it can now cause Emacs to abort.
1370 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1372 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1373 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1374 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1423 * editfns.c [HAVE_PWD_H]: Include grp.h.
1425 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1427 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1429 Fix permissions bugs with setgid directories etc. (Bug#13125)
1430 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1431 to mark it as a placeholder. The old value was often wrong.
1432 The only user of this attribute has been changed to use
1433 file-ownership-preserved-p instead, with its new group arg.
1434 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1436 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
1438 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
1439 Keep selected_window and selected_frame in sync.
1441 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1443 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1444 try to get accurate owner and group information from NT file
1445 security APIs. This is to make most callers of 'stat' and
1446 'lstat', which don't need that information, much faster.
1448 * dired.c (Ffile_attributes) [WINDOWSNT]:
1449 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1450 owner and group information from 'lstat'.
1452 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1454 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1455 as that confuses set-auto-coding, so insist on the head-read
1456 returning the full 1024 bytes. Let lseek compute the tail offset;
1457 less work for us. Do not ignore I/O errors when reading the tail.
1459 * xdisp.c: Minor style fixes.
1460 (init_iterator): Hoist assignment out of if-expression.
1461 (markpos_of_region): Callers now test for sign, not for -1.
1463 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
1465 Minor redisplay optimization when the region length is zero.
1466 * xdisp.c (markpos_of_region): New function.
1467 (init_iterator): Do not highlight the region of zero length.
1468 (redisplay_window): Check whether the region is of non-zero length.

1480 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1481 files, fixing a regression from 24.2.
1482 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1484 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1486 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1487 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1488 Remove unnecessary S_ISLNK test, as (contra the comments) this
1489 function can't copy symlinks. Improve quality of error message
1490 when attempting to copy files that are neither regular files nor

1498 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1499 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1501 2012-12-12 Daniel Colascione <dancol@dancol.org>
1503 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1504 the dumped Emacs is not a sparse file, greatly improving Cygwin
1505 "make bootstrap" performance.
1507 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1509 * inotify.c (inotify_callback): Generate an Emacs event for every
1510 incoming inotify event.
1512 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1514 * xdisp.c (handle_face_prop): Fix logic of computing
1515 it->start_of_box_run_p.
1516 (append_space_for_newline): If the glyph row is R2L, reset the
1517 iterator's end_of_box_run_p flag before prepending the space glyph.
1518 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1519 iterator's start_of_box_run_p flag before prepending the stretch.
1520 (append_glyph, produce_image_glyph, append_composite_glyph)
1521 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1522 left_box_line_p and right_box_line_p flags of the glyph for R2L
1523 glyph rows. (Bug#13011)
1525 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1527 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
1528 if changed buffer is not shown in a window.
1529 * insdel.c (prepare_to_modify_buffer): Likewise.
1530 * window.c (replace_buffer_in_windows_safely): Do nothing
1531 if buffer is not shown in a window.
1532 (Fforce_window_update): Likewise if string or buffer argument
1535 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1537 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1538 encoded_file_name, which is what it is.
1540 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1542 Consistently use marker_position and marker_byte_position.
1543 * fringe.c (Ffringe_bitmaps_at_pos):
1544 * indent.c (Fvertical_motion):
1545 * insdel.c (prepare_to_modify_buffer):

1564 Windows file notification functionality unless WINDOWSNT.
1566 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1569 * w32fns.c (cache_system_info): Initialize the global hinst
1570 variable here so various initialization calls DTRT.
1572 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1573 (hinst): Remove unneeded extern declaration.
1574 (_start): Remove initialization of above variables; remove
1575 initialization of hinst, as cache_system_info now does that.
1577 * emacs.c (main): Call cache_system_info early in startup; we
1578 previously weren't calling it in Cygwin builds.
1580 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
1581 Teach the autoconf build system how to compile a Windows resource file
1582 and link it to Emacs.

1613 indication whether any WM_EMACS_FILENOTIFY messages were found in
1616 * w32inevt.c (handle_file_notifications): New function.

1717 * w32.c (unsetenv): Return 0 if the input string is too long.
1719 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1721 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1722 * alloc.c (xputenv): New function.
1723 * dbusbind.c (Fdbus_init_bus):
1725 * xterm.c (x_term_init):
1726 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

1736 no longer needed here.

1740 (syms_of_editfns): Don't initialize initial_tz;
1741 init_editfns now does it.

1762 Remove USG and vlimit methods; no longer used these days.
1763 Add #error catchall just in case.
1765 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1766 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1767 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

1774 (abbr_to_signal): New static function.
1775 (Fsignal_process): Use it to convert signal names to ints.
1776 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than

1792 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1794 * frame.c (make_frame): Do not set window's buffer to t.
1795 * window.c (Fsplit_window_internal): Likewise. Previously it was
1796 used to indicate that the window is being set up. Now we use
1797 set_window_buffer for all new windows, so the condition in ...
1798 (Fset_window_buffer): ... is always true and can be removed.
1800 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1802 Convenient macro to check whether the buffer is hidden.
1803 * buffer.h (BUFFER_HIDDEN_P): New macro.

1812 loop and return zero. (Bug#13086)
1814 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1816 * frame.h (x_char_width, x_char_height): Remove prototypes.

1829 Fix a recently-introduced delete-process race condition.
1830 * callproc.c, process.h (record_kill_process):
1831 New function, containing part of the old call_process_kill.
1832 (call_process_kill): Use it.
1833 This does not change call_process_kill's behavior.
1834 * process.c (Fdelete_process): Use record_kill_process to fix a
1835 race condition that could cause Emacs to lose track of a child.
1837 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1839 Avoid code duplication between prev_frame and next_frame.
1840 * frame.c (candidate_frame): New function. Add comment.
1841 (prev_frame, next_frame): Use it. Adjust comment.
1843 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1845 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1846 fails, signal an error instead of continuing with an empty
1848 Encode expanded temp file pattern before passing it to mkstemp or
1851 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1852 Encode the file name before passing it to dostounix_filename, in
1853 case it will downcase it (under w32-downcase-file-names).
1856 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1858 Minor call-process cleanups.
1859 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1860 at the same time as other platforms, to simplify analysis.
1861 No need for fd0_volatile since we have synch_process_fd.
1862 Avoid needless emacs_close; arg is always negative.
1864 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1866 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1869 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1871 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1872 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1873 and mouse_face_hidden members to a bitfields.

1878 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1879 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1880 members to a bitfields.
1882 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1884 Don't let call-process be a zombie factory (Bug#12980).
1885 Fixing this bug required some cleanup of the signal-handling code.
1886 As a side effect, this change also fixes a longstanding rare race
1887 condition whereby Emacs could mistakenly kill unrelated processes,
1888 and it fixes a bug where a second C-g does not kill a recalcitrant
1889 synchronous process in GNU/Linux and similar platforms.
1890 The patch should also fix the last vestiges of Bug#9488,
1891 a bug which has mostly been fixed on the trunk by other changes.
1892 * callproc.c, process.h (synch_process_alive, synch_process_death)
1893 (synch_process_termsig, sync_process_retcode):
1894 Remove. All uses removed, to simplify analysis and so that
1895 less consing is done inside critical sections.
1896 * callproc.c (call_process_exited): Remove. All uses replaced
1897 with !synch_process_pid.
1898 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1899 These take the role of what used to be in unwind-protect arg.
1901 (block_child_signal, unblock_child_signal):
1902 New functions, to avoid races that could kill innocent-victim processes.
1903 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1904 (call_process_kill): Record killed processes as deleted, so that
1905 zombies do not clutter up the system. Do this inside a critical
1906 section, to avoid a race that would allow the clutter.
1907 (call_process_cleanup): Fix code so that the second C-g works again
1908 on common platforms such as GNU/Linux.
1909 (Fcall_process): Create the child process in a critical section,
1910 to fix a race condition. If creating an asynchronous process,
1911 record it as deleted so that zombies do not clutter up the system.
1912 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1913 light of these changes. Omit unnecessary call to emacs_close
1914 before failure, as the unwind-protect code does that.
1915 * callproc.c (call_process_cleanup):
1916 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1917 * process.c (record_deleted_pid): New function, containing
1918 code refactored out of Fdelete_process.
1919 (Fdelete_process): Use it.
1920 (process_status_retrieved): Remove. All callers changed to use
1921 child_status_change.
1922 (record_child_status_change): Remove, folding its contents into ...
1923 (handle_child_signal): ... this signal handler. Now, this
1924 function is purely a handler for SIGCHLD, and is not called after
1925 a synchronous waitpid returns; the synchronous code is moved to
1926 wait_for_termination. There is no need to worry about reaping
1927 more than one child now.
1928 * sysdep.c (get_child_status, child_status_changed): New functions.
1929 (wait_for_termination): Now takes int * status and bool
1930 interruptible arguments, too. Do not record child status change;
1931 that's now the caller's responsibility. All callers changed.
1932 Reimplement in terms of get_child_status.
1933 (wait_for_termination_1, interruptible_wait_for_termination):
1934 Remove. All callers changed to use wait_for_termination.
1935 * syswait.h: Include <stdbool.h>, for bool.
1936 (record_child_status_change, interruptible_wait_for_termination):
1938 (record_deleted_pid, child_status_changed): New decls.
1939 (wait_for_termination): Adjust to API changes noted above.
1941 * bytecode.c, lisp.h (Qbytecode): Remove.
1942 No longer needed after 2012-11-20 interactive-p changes.
1944 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1946 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1947 the scroll margin, move point outside the margin. (Bug#13055)

1951 * gtkutil.c (my_log_handler): New function.
1952 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1954 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1956 * lisp.h (modify_region): Rename to...
1957 (modify_region_1): ...new prototype.
1958 * textprop.c (modify_region): Now static. Adjust users.
1959 * insdel.c (modify_region): Rename to...
1960 (modify_region_1): ...new function to work with current buffer.
1961 Adjust comment and users. Use true and false for booleans.
1963 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1965 * alloc.c (free_save_value): New function.
1966 (safe_alloca_unwind): Use it.
1967 * lisp.h (free_save_value): New prototype.
1968 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1970 (save_excursion_restore): Adjust to match saved data structure.
1971 Use free_save_value to offload some work from GC. Drop obsolete
1974 2012-12-03 Chong Yidong <cyd@gnu.org>
1976 * fileio.c (Vauto_save_list_file_name): Doc fix.
1978 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1980 * w32fns.c: Remove prototype of atof.
1981 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1983 (file_dialog_callback): Make it UINT_PTR.
1985 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1988 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1989 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1992 2012-12-03 Glenn Morris <rgm@gnu.org>
1994 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1996 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1998 Fix xpalloc confusion after memory is exhausted.
1999 * alloc.c (xpalloc): Comment fix.
2000 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2001 and signals an error, do not clear charset_table_size, as
2002 charset_table is still valid.
2003 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2005 Use execve to avoid need to munge environ (Bug#13054).
2006 * callproc.c (Fcall_process):
2007 * process.c (create_process):
2008 Don't save and restore environ; no longer needed.
2009 * callproc.c (child_setup):
2010 Use execve, not execvp, to preserve environ.
2012 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2014 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2016 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2018 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2019 display for sliced images (Bug#10500).
2021 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2023 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2025 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2026 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2028 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2030 * xdisp.c (window_outdated): Remove eassert since it hits
2031 some suspicious corner cases (see Bug#13007 and Bug#13012).
2032 (mode_line_update_needed): New function.
2033 (redisplay_internal, redisplay_window): Use it.
2034 (ensure_selected_frame): New function.
2035 (redisplay_internal, unwind_redisplay): Use it.
2036 (redisplay_internal): Move comment about buffer_shared...
2037 (buffer_shared_and_changed): ...near to its real use.
2039 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2041 * callproc.c (Fcall_process): Don't misreport vfork failure.
2043 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2045 * callproc.c (Fcall_process): Fix vfork portability problems.
2046 Do not assume that fd[0], count, filefd, and save_environ survive
2047 vfork. Fix bug whereby wrong errno value could be reported for
2048 pipe failure. Some minor cleanups, too, as follows. Move buf and
2049 bufsize to the context where they're needed. Change new_argv to
2050 be of type char **, as this is more convenient and avoids casts.
2051 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2052 Now local constants, not macros.
2054 2012-11-18 Kenichi Handa <handa@gnu.org>
2056 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2057 for the variable "f".

2061 * font.c (font_unparse_xlfd): Exclude special characters from the
2062 generating XLFD name.

2077 * lread.c (readbyte_from_file): Assume EINTR is defined.
2078 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2079 Assume EIO and EAGAIN are defined.
2080 * unexcoff.c (write_segment): Assume EFAULT is defined.
2082 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2084 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2087 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2088 highlighting on the frame was cleared. Prevents assertion
2089 violations when repeatedly clicking on the "Top" link of the
2090 "bread-crumbs" in Info buffers.

2104 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2105 between bpos_covered and bpos_max. This fixes cursor display when
2106 several display strings follow each other.
2108 * .gdbinit (pgx): If the glyph's object is a string, display the
2109 pointer to string data, rather than the value of the string object
2110 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2112 * indent.c (Fvertical_motion): If the starting position is covered
2113 by a display string, return to one position before that, to avoid
2114 overshooting it inside move_it_to. (Bug#12930)
2116 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2118 * frame.h (struct frame): Remove display_preempted member

2121 * w32menu.c (pending_menu_activation): Remove since not
2123 (set_frame_menubar): Adjust user.
2124 * w32term.h (struct x_output): Drop outdated #if 0 code.
2125 (struct w32_output): Use bitfields for explicit_parent,
2126 asked_for_visible and menubar_active members.
2127 Drop unused pending_menu_activation member.
2128 * xterm.h (struct x_output): Drop outdated #if 0 code.
2129 Use bitfields for explicit_parent, asked_for_visible,
2130 has_been_visible and net_wm_state_hidden_seen members.
2132 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2134 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2135 of a literal "/". (Bug#12955)
2136 (gl-stamp): Invoke fc.exe directly, not through cmd.

2141 * dired.c: Assume HAVE_DIRENT_H.
2142 (NAMLEN): Remove, replacing with ...
2143 (dirent_namelen): New function. All uses changed. Use the GNU macro
2144 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2145 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2146 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2147 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2149 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2150 * ndir.h: Rename to ../nt/inc/dirent.h.
2151 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2152 Do not include <dirent.h>; no longer needed.
2153 * w32.c: Include <dirent.h> rather than "ndir.h".
2155 2012-11-23 Chong Yidong <cyd@gnu.org>
2157 * xftfont.c (xftfont_open): Remove duplicate assignment.
2159 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2161 * alloc.c (Fgarbage_collect): Unblock input after clearing
2162 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2163 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2164 * msdos.c (IT_frame_up_to_date): Use it here...
2165 * w32term.c (w32_frame_up_to_date): ...here...
2166 * xterm.c (XTframe_up_to_date): ...and here...
2167 * nsterm.m (ns_frame_up_to_date): ...but not here.
2168 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2170 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2171 Do not check whether GC is in progress.
2173 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2175 * xdisp.c (window_buffer_changed): New function.
2176 (update_menu_bar, update_tool_bar): Use it to
2177 simplify large 'if' statements.
2178 (redisplay_internal): Generalize commonly used
2179 'tail' and 'frame' local variables.
2181 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2183 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2184 with Windows system header.
2186 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2188 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2189 * alloc.c: Assume unistd.h exists.

2193 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2194 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2195 * w32.h (getcwd): Remove decl.
2197 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

2203 2012-11-21 Ken Brown <kbrown@cornell.edu>
2205 * emacs.c (main): Set the G_SLICE environment variable for all
2206 Cygwin builds, not just GTK builds. See
2207 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2209 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2211 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2212 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2213 Define for the MSVC compiler.
2215 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2217 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2218 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2219 dostounix_filename. Prevents crashes down the road, because
2220 dostounix_filename assumes it gets a unibyte string.
2221 Reported by Michel de Ruiter <michel@sentient.nl>, see

2253 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2254 (syms_of_eval): Remove corresponding defsubr.
2255 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2257 2012-11-19 Daniel Colascione <dancol@dancol.org>
2259 * w32fns.c (Fx_file_dialog):
2260 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2261 cygwin_convert_file_name*.
2263 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2264 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2266 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2268 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2270 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2272 * w32select.c: Include w32common.h before w32term.h, so that
2273 windows.h gets included before w32term.h uses some of its
2274 features, see below.
2276 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2278 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2282 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2284 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2285 (ns_select): Return at once if events are held (Bug#12834).
2287 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2289 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2290 Needed following 2012-10-20 change. (Bug#12902)
2292 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2294 * w32proc.c (waitpid): Remove unused label get_result.
2296 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2298 * makefile.w32-in (SYSWAIT_H): New macro.
2299 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2300 ($(BLD)/sysdep.$(O)): Update dependencies.
2302 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2304 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2305 * callproc.c (relocate_fd): Assume F_DUPFD.
2306 * emacs.c, term.c (O_RDWR): Remove.
2307 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2308 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2309 * nsterm.m: Assume <fcntl.h> exists.
2310 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2311 (create_pty, Fmake_network_process, server_accept_connection)
2312 (wait_reading_process_output, init_process_emacs):
2314 (wait_reading_process_output): Put in a special case for WINDOWSNT
2315 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2316 It's not clear this is needed, but it's a more-conservative change.
2317 (create_process): Assume FD_CLOEXEC.
2318 (create_process, create_pty): Assume O_NOCTTY.
2319 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2320 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2321 Omit if not DOS_NT, since F_GETFL is not defined there.
2322 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2323 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2325 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2326 lack it, since gnulib guarantees this.
2327 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2329 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2331 * w32.c (faccessat): Pretend that directories have the execute bit
2332 set. Emacs expects that, e.g., in files.el:cd-absolute.
2334 * w32proc.c (create_child): Don't clip the PID of the child
2335 process to fit into an Emacs integer, as this is no longer a
2337 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2338 reaping only the process specified by PID argument, if that is
2339 positive. Use PID instead of dead_child to know which process to
2340 reap. Wait for the child to die only if WNOHANG is not in
2342 (sys_select): Don't set dead_child.
2344 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2345 as it is no longer needed.
2347 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2349 (record_child_status_change): Remove the setting of
2350 record_at_most_one_child for the !WNOHANG case.
2352 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2354 Fix problems in ns port found by static checking.
2355 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2356 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2357 not to process group.
2358 (ns_select): Use emacs_write, not write, as that's more robust
2359 in the presence of signals.
2360 (fd_handler:): Check for read errors.
2362 2012-11-16 Glenn Morris <rgm@gnu.org>
2364 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2366 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2368 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2370 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2372 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2373 use the same value of thread handle.
2374 (start_timer_thread): If the timer thread exited (due to error),
2375 clean up by closing the two handles it used. Duplicate the caller
2376 thread's handle here, so it gets duplicated only once, when
2377 launching the timer thread. Set priority of the timer thread, not
2379 (getitimer): Don't duplicate the caller thread's handle here.
2382 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2384 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2387 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2389 Remove no-longer-used pty_max_bytes variable.
2390 * process.c (pty_max_bytes): Remove; unused.
2391 (send_process): Do not set it.
2393 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2395 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2396 Update dependencies.
2398 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2400 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2401 This follows up on the 2012-09-29 patch that removed indirection
2402 for the 'function' field. Reported by Sergey Vinokurov in
2403 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2405 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2407 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2408 different name, as the MS runtime does not have such a function,
2409 and probably never will.) All callers changed. Ignore DIRFD
2410 value if PATH is an absolute file name, to match Posix spec
2411 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2414 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2416 * xdisp.c (echo_area_display, redisplay_internal):
2417 Omit redundant check whether frame_garbaged is set.
2419 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2421 Use faccessat, not access, when checking file permissions (Bug#12632).
2422 This fixes a bug that has been present in Emacs since its creation.
2423 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2424 which must set some sort of record. (Torek's bug report was against
2425 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2426 same common flaw.) See Torek's Usenet posting
2427 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2428 Posted: Fri Apr 8 14:18:56 1983.
2429 * Makefile.in (LIB_EACCESS): New macro.
2431 * callproc.c (init_callproc):
2432 * charset.c (init_charset):
2433 * fileio.c (check_existing, check_executable, check_writable)
2435 * lread.c (openp, load_path_check):
2436 * process.c (allocate_pty):
2438 Use effective UID when checking permissions, not real UID.
2439 * callproc.c (init_callproc):
2440 * charset.c (init_charset):
2441 * lread.c (load_path_check, init_lread):
2442 Test whether directories are accessible, not merely whether they exist.
2443 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2444 * fileio.c (check_existing, check_executable, check_writable)
2446 Use symbolic names instead of integers for the flags, as they're
2448 (check_writable): New arg AMODE. All uses changed.
2449 Set errno on failure.
2450 (Ffile_readable_p): Use faccessat, not stat + open + close.
2451 (Ffile_writable_p): No need to call check_existing + check_writable.
2452 Just call check_writable and then look at errno. This saves a syscall.
2453 dir should never be nil; replace an unnecessary runtime check
2454 with an eassert. When checking the parent directory of a nonexistent
2455 file, check that the directory is searchable as well as writable, as
2456 we can't create files in unsearchable directories.
2457 (file_directory_p): New function, which uses 'stat' on most platforms
2458 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2459 (Ffile_directory_p, Fset_file_times): Use it.
2460 (file_accessible_directory_p): New function, which uses a single
2461 syscall for efficiency.
2462 (Ffile_accessible_directory_p): Use it.
2463 * xrdb.c (file_p): Use file_directory_p.
2464 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2465 * lread.c (openp): When opening a file, use fstat rather than
2466 stat, as that avoids a permissions race. When not opening a file,
2467 use file_directory_p rather than stat.
2468 (dir_warning): First arg is now a usage string, not a format.
2469 Use errno. All uses changed.
2470 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2471 that merely introduced a race.
2472 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2473 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2474 and similarly for the other O_* flags.
2475 * w32.c (sys_faccessat): Rename from sys_access and switch to
2476 faccessat's API. All uses changed.
2477 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2478 (magic_db): Rename from magic_file_p.
2479 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2480 char *, so that we don't have to test for file existence
2481 separately from opening the file for reading. This removes a race
2482 fixes a permission-checking problem, and simplifies the code.
2484 (file_p): Remove; no longer needed.
2486 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2488 Omit glyphs initialization at startup.
2489 * dispnew.c (glyphs_initialized_initially_p): Remove.
2490 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2491 (Fredraw_frame): Move actual code from here...
2492 (redraw_frame): ...to here. Add eassert. Adjust comment.
2493 (Fredraw_display): Use redraw_frame.
2494 * xdisp.c (clear_garbaged_frames): Likewise.
2496 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2498 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2499 passed to pint2str and pint2hrstr to be at most the size of the
2500 frame's decode_mode_spec_buffer. This avoids crashes with very
2501 large values of FIELD_WIDTH argument to decode_mode_spec.
2504 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2506 Fix a race with verify-visited-file-modtime (Bug#12863).
2507 Since at least 1991 Emacs has ignored an mtime difference of no
2508 more than one second, but my guess is that this was to work around
2509 file system bugs that were fixed long ago. Since the race is
2510 causing problems now, let's remove that code.
2511 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2512 whose time stamp is off by no more than a second. Insist that the
2513 file time stamps match exactly.
2515 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2517 * frame.h (struct frame): Convert external_tool_bar member to
2518 1-bit unsigned bitfield.
2519 * termhooks.h (struct terminal): Remove mouse_moved member since
2520 all users are long dead. Adjust comment on mouse_position_hook.
2522 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2524 Simplify by using FOR_EACH_FRAME here and there.
2525 * frame.c (next_frame, prev_frame, other_visible_frames)
2526 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2527 * w32term.c (x_window_to_scroll_bar): Likewise.
2528 * window.c (window_list): Likewise.
2529 * xdisp.c (x_consider_frame_title): Likewise.
2530 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2531 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2532 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2533 * xmenu.c (menubar_id_to_frame): Likewise.
2534 * xselect.c (frame_for_x_selection): Likewise.
2535 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2536 (x_window_to_menu_bar): Likewise.
2537 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2539 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2541 * data.c (Qdefalias_fset_function): Now static.
2543 Another tweak to vectorlike_header change.
2544 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2545 Remove, and replace all uses with ...
2546 (next_in_free_list, set_next_in_free_list):
2547 New functions, which respect C's aliasing rules better.
2549 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2551 * window.c (list4i): Rename from 'quad'. All uses changed.
2552 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2554 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2556 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2557 warning about mixing declarations and code in ISO C90.
2559 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2561 * window.c (Fsplit_window_internal): Set combination limit of
2562 new parent window to t iff Vwindow_combination_limit is t;
2563 fixing a regression introduced with the change from 2012-09-22.
2564 (Fset_window_combination_limit): Fix doc-string.
2566 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2568 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2569 amount when the scroll margins are too large. When scrolling
2570 backwards in the buffer, give up if cannot reach point or the
2571 scroll margin within a reasonable number of screen lines.
2572 Fixes point position in window under scroll-up/down-aggressively when
2573 point is positioned many lines beyond the window top/bottom.
2576 * ralloc.c (relinquish): If real_morecore fails to return memory
2577 to the system, don't crash; instead, leave the last heap
2578 unchanged and return. (Bug#12774)
2580 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2582 * lisp.h (AUTOLOADP): New macro.
2583 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2584 * data.c (Ffset): Remove special ad-advice-info handling.
2585 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2587 (Finteractive_form): Simplify.
2588 (Fquo): Don't insist on having at least 2 arguments.
2589 (Qdefalias_fset_function): New var.
2591 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2593 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2595 * nsfont.m (Qcondensed, Qexpanded): New variables.
2596 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2597 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2599 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2601 Fix recently introduced crash on MS-Windows (Bug#12839).
2602 * w32term.h (struct scroll_bar): Use convenient header.
2603 (SCROLL_BAR_VEC_SIZE): Remove.
2604 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2606 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2608 Tweak last vectorlike_header change.
2609 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2610 vectorlike object on the free list. This is introduced to avoid
2611 some (but not all) pointer casting and aliasing problems, see
2612 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2613 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2615 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2617 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2619 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2620 been removed, so remove them here also.
2622 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2624 * doc.c (Fdocumentation): Handle new property
2625 dynamic-docstring-function to replace the old ad-advice-info.
2627 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2629 * fns.c (Qeql, hashtest_eq): Now static.
2631 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2633 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2634 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2635 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2636 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2638 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2640 Use same hash function for hashfn_profiler as for hash_string etc.
2641 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2642 * lisp.h (sxhash_combine): New inline function, with the contents
2643 of the old SXHASH_COMBINE.
2644 * profiler.c (hashfn_profiler): Use it, instead of having a
2645 special hash function containing a comparison that always yields 1.
2647 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2649 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2650 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2651 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2654 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2656 * image.c (xpm_make_color_table_h): Fix compiler error because
2657 make_hash_table changed.
2659 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2661 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2663 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2665 Use ad-hoc comparison function for the profiler's hash-tables.
2666 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2667 (make_log): Use them.
2668 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2669 call Fequal any more.
2670 (Ffunction_equal): New function.
2671 (cmpfn_profiler, hashfn_profiler): New functions.
2672 (syms_of_profiler): Initialize them.
2673 * lisp.h (struct hash_table_test): New struct.

2678 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2679 (hash_lookup, hash_remove_from_table): Move assertion checking of
2680 hashfn result here. Check hash-equality before calling cmpfn.

2687 * print.c (print_object): Adjust to new hash-table struct.
2688 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2690 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2692 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2693 value of w32-scroll-lock-modifier is neither nil nor one of the
2694 known key modifiers. (Bug#12806)
2696 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2698 Shrink struct vectorlike_header to the only size field.
2699 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2701 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2702 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2703 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2704 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2705 information from the vector header. Adjust comment.
2706 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2707 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2709 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
2710 (struct vectorlike_header): Remove next member. Adjust comment.

2713 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
2714 (sweep_string, lisp_malloc): Remove useless prototypes.
2715 (enum mem_type): Adjust comment.
2716 (NEXT_IN_FREE_LIST): New macro.
2717 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2718 (Fmake_bool_vector): Likewise.
2719 (struct large_vector): New type to represent allocation unit for
2720 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2721 (large_vectors): Change type to struct large_vector.
2722 (allocate_vector_from_block): Simplify.
2723 (PSEUDOVECTOR_NBYTES): Replace with...
2724 (vector_nbytes): ...new function. Adjust users.
2725 (sweep_vectors): Adjust processing of large vectors.
2726 (allocate_vectorlike): Likewise.
2727 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2728 Add easserts. Adjust XSETPVECTYPESIZE usage.
2729 (allocate_buffer): Use BUFFER_PVEC_INIT.
2730 (live_vector_p): Adjust to match large vector.
2731 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2732 * buffer.h (struct buffer): Add next member.
2733 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2735 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2736 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2737 (copy_hash_table): Adjust to match vector header change.
2738 * lread.c (defsubr): Use XSETPVECTYPE.
2739 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2740 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2741 (xvecsize): New command.
2743 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2745 * keyboard.c (event_to_kboard): Do not dereference
2746 frame_or_window field of SELECTION_REQUEST_EVENT
2747 and SELECTION_CLEAR_EVENT events (Bug#12814).
2748 * xterm.h (struct selection_input_event): Adjust comment.
2750 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2752 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2753 such as Scroll Lock, if the respective keys are treated as
2754 function keys, not as modifiers. This avoids destroying non-ASCII
2755 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2757 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2759 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2761 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2763 Restore some duplicate definitions (Bug#12814).
2764 This undoes part of the 2012-11-03 changes. Some people build
2765 with plain -g rather than with -g3, and they need the duplicate
2766 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2767 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2768 Define as macros, as well as as enums or as constants.
2770 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2772 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2773 to keypad keys (Bug#12816).
2775 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2777 Minor adjustments of recently-changed frame functions.
2778 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2779 known to be a frame (we're in the FRAMEP branch).
2780 * lisp.h (Qframep): Remove decl. frame.h declares this.
2781 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2782 since they're meant for Lisp fixnum values.
2784 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2786 * window.c (Fwindow_combination_limit): Revert to the only
2787 required argument and adjust docstring as suggested in
2788 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2789 by Martin Rudalics <rudalics@gmx.at>.

2805 (frame_buffer_list, frame_buffer_predicate): Remove.
2806 * lisp.h (frame_buffer_predicate): Remove prototype.
2807 * buffer.c (Fother_buffer): Use decode_any_frame.
2808 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2809 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2810 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2811 (Fclose_font, Ffont_info): Use decode_live_frame.
2812 * fontset.c (check_fontset_name): Likewise.
2813 * terminal.c (Fframe_terminal): Likewise.
2814 * w32fns.c (check_x_frame): Likewise.
2815 * window.c (Fminibuffer_window, Fwindow_at)
2816 (Fcurrent_window_configuration): Likewise.

2830 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2831 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)

2835 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2836 (Fwindow_combination_limit): Allow zero number of arguments.
2838 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2840 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2842 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2843 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2844 file descriptor 2 for standard error. (Bug#12805)
2846 2012-11-05 Chong Yidong <cyd@gnu.org>
2848 * process.c (wait_reading_process_output): Revert previous change.
2850 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2852 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2853 This removes code that has been obsolete since around 1990.
2854 * callproc.c (Fcall_process):
2856 * process.c (create_process):
2857 * term.c (dissociate_if_controlling_tty):
2858 Assume setsid exists.
2859 * callproc.c (child_setup): Assume setpgid exists and behaves as
2860 per POSIX.1-1988 or later.
2861 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2862 * emacs.c (shut_down_emacs):
2863 * sysdep.c (sys_suspend, init_foreground_group):
2864 Assume getpgrp behaves as per POSIX.1-1998 or later.
2865 * msdos.c (setpgrp): Remove.
2866 (tcgetpgrp, setpgid, setsid): New functions.
2867 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2868 * term.c (no_controlling_tty): Remove; unused.
2869 * w32proc.c (setpgrp): Remove.
2870 (setsid, tcgetpgrp): New functions.
2872 Simplify by assuming __fpending.
2873 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2874 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2875 Do not assume that __fpending's result fits in int.
2877 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2879 Remove EMACS_OUTQSIZE+sleep hack.
2880 * dispnew.c (update_frame_1): Remove hack for terminals slower
2881 than 2400 bps, which throttled Emacs by having it sleep.
2882 This code hasn't worked since at least 2007, when the multi-tty stuff
2883 was added, and anyway those old terminals are long dead.
2884 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2885 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2887 Fix data-loss with --version (Bug#9574).
2888 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2889 as we can't assume that emacs_strerror is initialized, and strerror
2890 is good enough here.
2891 (main): Invoke atexit earlier, to catch earlier instances of
2892 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2894 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2896 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2897 (keyDown): Remap keypad keys to X11 virtual key codes.
2899 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2901 Fix data-loss with --batch (Bug#9574).
2902 * emacs.c: Include <close-stream.h>.
2903 (close_output_streams): New function.
2904 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2905 and handles errors appropriately.
2906 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2909 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2910 The symptom is a diagnostic "GLib-WARNING **: In call to
2911 g_spawn_sync(), exit status of a child process was requested but
2912 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2913 waitpid(), so exit status can't be returned." The diagnostic
2914 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2915 The real bug is a race condition between Emacs and glib: Emacs
2916 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2917 so that glib can't find it. Work around the bug by invoking
2918 waitpid only on subprocesses that Emacs itself creates.
2919 * process.c (create_process, record_child_status_change):
2920 Don't use special value -1 in pid field, as the caller now must
2921 know the pid rather than having the callee infer it.
2922 The inference was sometimes incorrect anyway, due to another race.
2923 (create_process): Set new 'alive' member if child is created.
2924 (process_status_retrieved): New function.
2925 (record_child_status_change): Use it.
2926 Accept negative 1st argument, which means to wait for the
2927 processes that Emacs already knows about. Move special-case code
2928 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2929 processes that have already been waited for, by testing and
2930 clearing new 'alive' member.
2931 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2932 now does this internally.
2933 (handle_child_signal): Let record_child_status_change do all
2934 the work, since we do not want to reap all exited child processes,
2935 only the child processes that Emacs itself created.
2936 * process.h (Lisp_Process): New boolean member 'alive'.
2938 Omit duplicate definitions no longer needed with gcc -g3.
2939 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2940 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2941 Define only as macros. There's no longer any need to also define
2942 these symbols as enums or as constants, since we now assume
2943 gcc -g3 when debugging.
2945 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2947 * lisp.mk: Adjust comments to the fact that term/internal is now
2948 loaded from loadup.el.
2950 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2951 (msdos_fatal_signal): New function.
2952 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2955 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2956 for GCC versions before 4.
2957 (emacs_raise): Define to call msdos_fatal_signal.
2959 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2960 iterator when starting in the middle of a display or overlay
2963 2012-11-03 Chong Yidong <cyd@gnu.org>
2965 * process.c (wait_reading_process_output): Clean up the last
2968 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2970 * process.c (wait_reading_process_output): Avoid a race condition
2971 with SIGIO delivery (Bug#11536).
2973 2012-11-03 Chong Yidong <cyd@gnu.org>
2975 * buffer.c (cursor_type): Untabify docstring.
2977 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2979 * frame.h (struct frame): Drop can_have_scroll_bars member
2980 which is meaningless for a long time. Adjust comments.
2981 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2982 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2984 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2986 * window.c (decode_next_window_args): Update window arg after
2987 calling decode_live_window and so fix crash reported at
2988 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2989 by Juanma Barranquero <lekktu@gmail.com>.
2990 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2991 * font.c (Ffont_at): Likewise.
2993 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2995 * widget.c (resize_cb): New function.
2996 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2997 (EmacsFrameResize): Check if all is up to date before changing frame
3000 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3002 Implement backtrace output for fatal errors on MS-Windows.
3003 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3004 (BACKTRACE_LIMIT_MAX): New macro.
3005 (w32_backtrace): New function.
3006 (emacs_abort): Use w32_backtrace when the user chooses not to
3007 attach a debugger. Update the text of the abort dialog.
3009 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3011 Window-related stuff cleanup here and there.
3012 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3013 Use decode_any_window.
3014 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3015 * xdisp.c (Fformat_mode_line): Likewise.
3016 * font.c (Ffont_at): Use decode_live_window.
3017 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3018 * window.c (decode_next_window_args): Likewise.
3019 (decode_any_window): Remove static.
3020 * window.h (decode_any_window): Add prototype.
3021 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3022 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3025 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3027 Remove pad from struct input_event.
3028 * termhooks.h (struct input_event): Remove padding field.
3030 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3031 member is never cons for a long time. Adjust comment.
3032 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3033 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3034 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3035 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3037 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3039 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3041 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3043 Fix crash when using Emacs as commit editor for git (Bug#12697).
3044 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3045 and it is configured in conf_post.h.
3046 (Fcall_process): Don't invoke both setsid and setpgid; the former
3047 is enough, if it exists.
3048 * callproc.c (Fcall_process, child_setup):
3049 * process.c (create_process): Use setpgid.
3050 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3052 * dispnew.c (init_display): Initialize the foreground group
3053 if we are running a tty display.
3054 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3055 * lisp.h (init_foreground_group): New decl.
3056 * sysdep.c (inherited_pgroup): New static var.
3057 (init_foreground_group, tcsetpgrp_without_stopping)
3058 (narrow_foreground_group, widen_foreground_group): New functions.
3059 (init_sys_modes): Narrow foreground group.
3060 (reset_sys_modes): Widen foreground group.
3062 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3064 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3066 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3068 * minibuf.c (read_minibuf): Restore current buffer since
3069 choose_minibuf_frame calling Fset_frame_selected_window may
3070 change it (Bug#12766).
3072 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3074 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3076 2012-10-30 Kenichi Handa <handa@gnu.org>
3078 * font.c (Ffont_at): If WINDOW is specified and it is not
3079 displaying the current buffer, signal an error.
3081 2012-10-29 Daniel Colascione <dancol@dancol.org>
3083 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3084 In preparation for fixing bug#12739, move these functions from
3087 * coding.h, coding.c: ... to here, and compile them only when
3088 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3089 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3091 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3093 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3094 (timer_loop, getitimer, setitimer): Use it instead of
3095 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3097 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3100 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3102 * nsterm.m (NO_APPDEFINED_DATA): New define.
3103 (last_appdefined_event_data): New variable
3104 (last_appdefined_event): Remove.
3105 (ns_select): Initialize t from last_appdefined_event_data instead
3106 of [last_appdefined_event data1].
3107 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3108 remove last_appdefined_event (Bug#12698).
3110 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3112 * frame.c (x_set_font): Catch internal error.
3114 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3116 Avoid overflow in w32 implementation of interval timers.
3117 When possible, for ITIMER_PROF count only times the main thread
3119 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3120 'volatile ULONGLONG' types. All the other data which was
3121 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3122 (GetThreadTimes_Proc): New typedef.
3123 (w32_get_timer_time): New function, returns a suitable time value
3125 (timer_loop): Enter critical section when accessing ULONGLONG
3126 values of the itimer_data struct, as these accesses are no longer
3127 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3128 Remove unused variable.
3129 (init_timers): Initialize s_pfn_Get_Thread_Times.
3130 (start_timer_thread): Don't assign itimer->caller_thread here.
3131 (getitimer): Assign itimer->caller_thread here.
3132 (setitimer): Always call getitimer to get the value of ticks_now.
3133 (sys_spawnve): Avoid compiler warning about format mismatch.
3135 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3137 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3138 mouse movement events if the menu bar is active. This avoids
3139 producing a busy "hour-glass" cursor by Windows if the mouse
3140 pointer is positioned over a tooltip shown for some menu item.
3142 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3144 Don't assume process IDs fit in int.
3145 * emacs.c (shut_down_emacs) [!DOS_NT]:
3146 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3147 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3148 Use pid_t, not int, to store process IDs, as 'int'
3149 is not wide enough on a few platforms (e.g., AIX and IRIX).
3151 2012-10-23 Kenichi Handa <handa@gnu.org>
3153 The following change is to make face-font-rescale-alist work
3154 correctly for non-ASCII fonts.
3156 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3157 (font_open_for_lface): Handle Vface_font_rescale_alist.
3159 2012-10-23 Chong Yidong <cyd@gnu.org>
3161 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3163 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3165 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3167 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3169 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3172 2012-10-21 Glenn Morris <rgm@gnu.org>
3174 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3176 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3178 Port to OpenBSD 5.1.
3179 * frame.c (Fmouse_position, Fmouse_pixel_position):
3180 * xdisp.c (produce_stretch_glyph):
3181 Declare local vars only when they're needed.
3182 This is clearer and avoids a warning on OpenBSD about unused vars.
3183 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3184 This is safer, and avoids OpenBSD warnings about unused vars.
3185 * keyboard.c (record_menu_key): Remove unnecessary decl.
3186 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3187 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3188 as our definition clashes with OpenBSD's.
3189 * xfaces.c (load_face_colors, check_lface_attrs)
3190 (get_lface_attributes_no_remap, get_lface_attributes)
3191 (lface_fully_specified_p, x_supports_face_attributes_p)
3192 (tty_supports_face_attributes_p, face_fontset, realize_face)
3193 (realize_x_face, realize_tty_face):
3194 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3195 merely Lisp_Object *. This is more informative and avoids
3196 a warning on OpenBSD about accessing beyond an object's size.
3198 2012-10-20 Chong Yidong <cyd@gnu.org>
3200 * lread.c (Fload): Doc fix (Bug#12592).
3202 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3204 * font.c (Ffont_at): Fix previous change.
3206 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3208 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3209 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3212 * alloc.c (NSTATICS): Decrease to 0x800.
3214 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
3216 * fns.c (Fnreverse): Include the problem element when signaling an
3219 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
3221 * nsterm.m (ns_select): Check writefds before call to
3222 FD_ISSET (Bug#12668).
3224 2012-10-18 Daniel Colascione <dancol@dancol.org>
3226 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3227 (staticpro): If we run out of staticpro slots, die with an
3228 informative error instead of just calling emacs_abort.
3230 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3232 Fix two flaws reported by Dmitry Antipov.
3233 * window.c (Ftemp_output_buffer_show): Remove.
3234 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
3235 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
3237 2012-10-17 Eli Zaretskii <eliz@gnu.org>
3239 * makefile.w32-in ($(BLD)/w32.$(O)):
3240 ($(BLD)/vm-limit.$(O)):
3242 ($(BLD)/unexw32.$(O)):
3243 ($(BLD)/fileio.$(O)):

3487 since unsigned is guaranteed to have that behavior and signed is not.
3488 (read_char): Use ptrdiff_t for string length.
3489 (get_input_pending): Remove first argument, since it was always
3490 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3491 and behave as if it had that value. Return new value of
3492 input_pending. All callers changed.
3493 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3494 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3497 All callers changed.

3523 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3525 * commands.h (immediate_quit): Remove duplicate decl.

3537 match what GetLastError returns. Explain why the function is
3540 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3541 'is_tooltip_frame', to avoid confusion with its global namesake.
3543 2012-10-08 Daniel Colascione <dancol@dancol.org>
3545 * xdisp.c (start_hourglass): Call w32_note_current_window when
3546 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3547 build that caused Emacs to display the hourglass cursor forever.
3549 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3550 which is broken under remote desktop, calculate the number of
3551 colors available for a display based on the display's number of
3552 planes and number of bits per pixel per plane. (bug#10397).
3554 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3556 * nsfont.m (Vfonts_in_cache): New variable.
3557 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3558 are used. Add cached fonts to Vfonts_in_cache.
3559 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3561 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3563 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now

3583 ($(BLD)/w32proc.$(O)): Add w32common.h.
3585 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now

3589 2012-10-08 Daniel Colascione <dancol@dancol.org>
3591 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3592 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3593 accidental message numbering hole. Change other messages to

3611 Remove duplicate definitions.
3613 * w32fns.c: Include w32common.h; include w32heap.h only in
3616 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3617 Use `report_file_error' instead of `error' in order to better
3618 inform users of what went wrong. Increase NTGUI_UNICODE file
3619 dialog box file name length to 32k, the maximum allowed by the NT
3622 * w32common.h: New file.
3623 (ROUND_UP, ROUND_DOWN, get_page_size)
3624 (get_allocation_unit, get_processor_type, get_w32_major_version)

3627 (OS_NT, os_subtype, cache_system_info): Move here.
3629 * unexw32.c, unexcw.c: Include w32common.h.
3631 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3632 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3633 to call syms_of_w32select.
3635 * cygw32.h: Remove obsolete EXFUN declarations.
3637 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3649 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3651 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3654 2012-10-08 Daniel Colascione <dancol@dancol.org>
3656 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3657 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3658 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

3660 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3661 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3662 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3663 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3664 now a supported configuration.
3666 * Makefile.in: consolidate image variables into LIBIMAGE; add
3667 W32_OBJ and W32_LIBS. Compile new files.
3670 (_DebPrint) declare tracing facility for W32 debugging. We need
3671 to unify tracing later.
3673 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3674 unconditional use of W32 Unicode functions. Cygwin runs only on
3675 100% Unicode operating systems.
3677 * cygw32.c: New file. Define Cygwin-specific facilities.
3678 (Fcygwin_convert_path_to_windows)
3679 (Fcygwin_convert_path_from_windows): New user functions for
3680 accessing Cygwin path-munging routines.
3682 * cygw32.h: New file.
3683 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3684 UTF-16LE strings temporarily inside non-Lisp-visible string
3687 (w32_strerror): Just what it says on the tin.
3689 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3690 also run for Cygwin; both systems have the same problem with using
3691 GUI facilities in a forked child. Also call syms_of_cygw32,
3692 syms_of_w32select in correct places.
3694 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3695 needs fork-then-exec for daemon launching.
3697 * font.h: Include frame.h.
3699 * image.c: Use the image library cache machinery only when we're
3700 compiling for native WINDOWSNT; Cygwin can use shared libraries
3701 like any other Unixlike system.
3703 * keyboard.c: Clarify a comment regarding the input loop.
3705 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3706 functions directly instead of trying to detect at runtime that our
3707 host operating system supports them. We make this change for two
3708 reasons: Cygwin lacks support for the multibyte character
3709 conversion functions used by the legacy menu code, and Cygwin
3710 never needs to rely on non-Unicode APIs.
3712 * unexw32.c (hinst): Declare extern.
3714 * w32.c: Change header order;
3715 (w32_strerror): Move to w32fns.c because we need it for
3716 non-WINDOWSNT builds.
3718 * w32.h: Add #error macro to make sure we don't include w32.h for
3719 Cygwin builds. Remove w32select declarations.
3721 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3722 w32fns.c. w32console.c is WINDOWSNT-only.
3724 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3725 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3727 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3728 (w32_major_version, w32_minor_version, w32_build_number)
3729 (os_subtype, sound_type): Define here
3730 (w32_defined_color): Make color parameter const for consistency
3731 with other _defined_color functions.
3732 (w32_createwindow): Unconditionally call w32_init_class instead of
3733 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3734 through the code is complex and unnecessary because class
3735 registration is practically free.
3736 (w32_name_of_message): New EMACSDEBUG-only function.
3737 (Fset_message_beep): Move here
3738 (Fx_open_connection): Require that the display name for Windows be
3739 "w32" for consistency, emacsclient disambiguation, and maybe, one
3740 day, multi-window-system support.
3741 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3742 Cygwin files for W32 GUI facilities, since these clearly don't
3743 expect Cygwin names.
3744 (_DebPrint): Define.
3745 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3746 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3747 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3748 (w32_last_error): Remove.
3750 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3752 * w32heap.c (syspage_mask): Declare here.
3753 (cache_system_info): Remove.
3755 * w32inevt.c (faked_key): Define globally, not statically.
3756 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3757 (w32_console_toggle_lock_key): Move to w32fns.c.
3759 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3761 * w32proc.c (_DebPrint): Move to w32fns.c.
3762 * w32select.c: Include string.h, stdio.h for Cygwin.
3763 * w32select.h: New File.
3765 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3767 (w32_message_fd): New variable. Under Cygwin, holds the file
3768 descriptor the system used to tell us about pending thread
3771 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3772 that prevented compilation under non-WINDOWSNT systems.
3774 (w32_initialize): Open /dev/windows and assign it to
3775 w32_message_fd. Provide w32 feature.
3777 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3778 (WM_EMACS_INPUT_READY): add.
3779 (prepend_msg, w32_message_fd): Declare globally.
3782 (keyboard_handle): Use only when WINDOWSNT.
3783 (notify_msg_ready): New function. Posts a message to the main
3784 thread's message queue under CYGWIN, which wakes up the main
3785 thread from select(2) by making the /dev/windows file descriptor
3786 ready. Under WINDOWSNT, it sets an event the same way the old
3789 (post, prepend_msg): Actually call notify_msg_ready instead of
3790 setting the input event directly.
3792 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3794 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3795 but it still has blocs in it, don't return it to the system,
3796 instead of aborting. (Bug#12402)
3798 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3800 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3802 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3803 MAC_OS_X_VERSION_10_6.
3804 (syms_of_nsterm): Remove comment about Panther and above for
3806 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

3808 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3810 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3811 MAC_OS_X_VERSION_10_4.
3813 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3814 MAC_OS_X_VERSION_10_2.
3816 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3818 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3819 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3821 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3822 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3823 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3824 Remove ns_in_resize check.
3825 (ns_clear_frame_area): Remove resize handle code.
3827 * nsfns.m (ns_in_resize): Remove.
3828 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3829 Remove ns_in_resize check.
3831 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3833 Improve sys_siglist detection.
3834 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3835 defined as a macro, as is done in Solaris.
3836 (sys_siglist_entries): New macro.
3837 (save_strsignal): Use it.
3838 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3839 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3841 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3843 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3844 fullscreen/Fullscreen.
3846 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3847 tobar_height is new.
3849 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3850 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3851 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3852 (windowDidResize:): Check for correct window if old style fullscreen.
3853 Capitalize word in comment. Remove incorrect comment.
3854 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3855 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3856 error in drawing background.
3857 (toggleFullScreen:): Remove comment. Rearrange calls.
3858 Set toolbar values to zero, save old height in tobar_height.
3859 Restore tool bar height when leaving fullscreen.
3860 (canBecomeMainWindow): New function.
3862 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3864 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3866 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3868 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3870 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3871 that time stamps of directories could also be changed.
3872 Don't request the too broad GENERIC_WRITE, only the more restrictive
3873 FILE_WRITE_ATTRIBUTES access rights.
3875 * fileio.c (Fset_file_times): Special-case ignoring errors for
3876 directories only on MSDOS, not on MS-Windows.
3878 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3880 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3882 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3884 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3885 see whether CreateFile failed.
3887 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3889 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3890 to avoid similar races.
3891 * keyboard.c (pending_signals): Now bool, not int.
3893 Port timers to OpenBSD, plus check for timer failures.
3894 OpenBSD problem reported by Han Boetes.
3895 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3897 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3898 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3899 like OpenBSD, which has timer_settime but does not declare it.
3900 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3901 whether to use itimerspec-related primitives. All uses of
3902 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3904 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3906 * profiler.c (handle_profiler_signal): Fix a malloc race
3907 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3909 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3911 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3913 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3915 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3916 consistent with the change in return value of 'safe_strsignal'.
3918 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3920 Prefer plain 'static' to 'static inline' (Bug#12541).
3921 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3922 (bidi_set_sor_type, bidi_push_embedding_level)
3923 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3924 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3928 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3929 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3930 Now 'static', not 'static inline'.
3932 Count overruns when profiling; change units to ns.
3933 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3934 Give extra weight to samples after overruns, to attempt to count
3935 the time more accurately.
3936 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3937 the underlying primitives nominally do ns.
3938 (Fprofiler_cpu_start): Document the change. Mention that
3939 the sampling intervals are only approximate.
3941 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3943 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3945 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3946 case for the special 0 coding-system.
3948 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3949 (Fmake_overlay): Remove redundant tests.
3950 (fix_start_end_in_overlays): Remove redundant recentering.
3952 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3954 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3955 Update dependencies.
3957 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3959 Fix a malloc race condition involving strsignal.
3960 A signal can arrive in the middle of a malloc, and Emacs's signal
3961 handler can invoke strsignal, which can invoke malloc, which is
3962 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3963 Fix it by altering the signal handler so that it does not invoke
3965 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3966 * process.c (status_message): Use const pointer, in case strsignal
3967 is #defined to safe_strsignal.
3968 * sysdep.c (sys_siglist, init_signals): Always define and
3969 initialize a substitute sys_siglist if the system does not define
3970 one, even if HAVE_STRSIGNAL.
3971 (safe_strsignal): Rename from strsignal. Always define,
3972 using sys_siglist. Return a const pointer.
3973 * syssignal.h (safe_strsignal): New decl.
3974 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3976 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3978 * w32proc.c (timer_loop): Fix code that waits for timer
3979 expiration, to avoid high CPU usage.
3981 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3983 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3984 (sweep_weak_table): Remove redundant prototypes.
3986 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3988 * emacs.c: Move the inclusion of TERM_HEADER after including
3989 windows.h on WINDOWSNT. This avoids compilation problems with
3992 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3994 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3995 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3996 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3997 as the previous version used 'void *'.
3999 * ralloc.c (ROUNDUP): Fix last change.
4000 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4003 * w32proc.c <disable_itimers>: New static flag.
4004 (init_timers): Initialize it to zero, after creating the critical
4005 sections used by the timer threads.
4006 (term_timers): Set to 1 before deleting the critical sections.
4007 (getitimer, setitimer): If disable_itimers is non-zero, return an
4008 error indication without doing anything. Reported by Fabrice
4009 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4010 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4012 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4015 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4016 term_ntproc after all the other bookkeeping, to get timers working
4017 as long as possible.
4019 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4021 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4022 Suggested by Juri Linkov in
4023 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4025 Prefer plain 'static' to 'static inline' (Bug#12541).
4026 With static functions, modern compilers inline pretty well by
4027 themselves; advice from programmers often hurts as much as it helps.
4028 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4029 this change shrinks the text size of the Emacs executable by 1.1%
4030 without affecting CPU significantly in my benchmark.
4031 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4032 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4106 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
4107 Now 'static', not 'static inline'.
4110 (bidi_copy_it): Do the whole copy with a single memcpy.
4111 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4113 Revert the FOLLOW-SYMLINKS change for file-attributes.
4114 Doing it right would require several changes to Tramp, and there's
4115 not enough time to get that tested before the freeze today.
4116 * dired.c (directory_files_internal, Ffile_attributes):
4119 * frame.c (x_report_frame_params): Port better to wider ints.
4120 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4121 or that pointers can be printed in 15 decimal digits.
4122 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4143 * w32heap.c (RVA_TO_PTR, allocate_heap, sbrk, init_heap)
4144 (round_heap): Use DWORD_PTR, ptrdiff_t and size_t instead of
4145 DWORD, long, and unsigned long, for compatibility with x64.
4146 (allocate_heap) [_WIN64]: Reserve 32GB of memory.

4153 * w32.c (init_environment, get_emacs_configuration): Support AMD64
4155 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
4156 compatibility with x64.
4158 * vm-limit.c (lim_data): Now size_t.
4159 (check_memory_limits): Adjust prototypes of real_morecore and
4160 __morecore to receive argument of type ptrdiff_t. Use size_t for

4303 Suggested by Eli Zaretskii in
4304 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
4306 2012-09-30 Eli Zaretskii <eliz@gnu.org>
4308 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
4309 HAVE_TIMER_SETTIME is defined.

4313 Profiler improvements: more-accurate timers, overflow checks.
4314 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4315 signal.h, setjmp.h. Include systime.h instead.

4323 All uses changed to store the new value.
4324 (handle_profiler_signal): Rename from sigprof_handler_1,
4325 for consistency with other handlers. Do not check whether
4326 cpu_log is a hash-table if garbage collecting, since it
4327 doesn't matter in that case.

4329 for consistency with other handlers.
4330 (setup_cpu_timer): New function, with much of what used to be in
4331 Fprofiler_cpu_start. Check for out-of-range argument.
4332 Prefer timer_settime if available, and prefer
4333 thread cputime clocks, then process cputime clocks, then
4334 monotonic clocks, to the old realtime clock. Use make_timeval
4335 to round more-correctly when falling back to setitimer.
4336 (Fprofiler_cpu_start): Use it.
4337 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4338 Don't assume that passing NULL as the 2nd argument of setitimer

4341 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4342 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4343 non-fatal signal handlers. Ignore SIGPROF on startup.
4344 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4345 in profiler.c, since sysdep.c now uses it.
4347 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4402 * charset.c, charset.h (maybe_unify_char): Now static.
4403 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4404 Since this stuff is now private to charset.c, there's no need for
4405 a public macro and no need to inline by hand.

4479 (sys_kill): Improve commentary.
4481 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4482 consistency with a signature of a signal handler. All callers
4484 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4485 install term_ntproc as a signal handler for SIGABRT, as that
4486 should be done by the dumped Emacs.
4488 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.

4605 ($(BLD)/w32xfns.$(O)): Update dependencies.
4607 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4609 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4610 fatal_error_backtrace.
4612 * w32proc.c (sys_kill): Undo last change: don't do anything when
4613 invoked to deliver SIGABRT to our own process. This is now
4614 handled by emacs_raise.
4616 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4618 * w32term.c (w32_read_socket): Remove leftover reference to
4619 interrupt_input_pending.
4621 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4623 Do not use SA_NODEFER.
4624 Problem reported by Dani Moncayo in
4625 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4627 * sysdep.c (emacs_abort): Do not reset signal handler.
4628 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4629 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4630 wanted even on POSIXish hosts, and it doesn't work on Windows.
4632 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4634 * xterm.c (x_term_init): Call fixup_locale before and after calling
4635 gtk_init (Bug#12392).
4637 2012-09-23 Chong Yidong <cyd@gnu.org>
4639 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4640 Vdynamic_library_alist.
4642 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4643 (Fgnutls_available_p): Caller changed.
4645 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4646 (Flibxml_parse_xml_region): Likewise.
4648 * dispextern.h (struct image_type): Remove arg from init function.
4650 * image.c (Finit_image_library, lookup_image_type)
4651 (define_image_type): Remove now-unneeded second arg.
4652 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4653 (init_tiff_functions, init_gif_functions, init_svg_functions):
4654 Arglist and w32_delayed_load calling convention changed.
4655 (gs_type): Remove init_gs_functions; there is no such function.
4656 (valid_image_p, make_image): Fix caller to lookup_image_type.
4658 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4660 Simplify and avoid signal-handling races (Bug#12471).
4662 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4663 Avoid recursive loop if there's a fatal error in the function itself.
4664 * atimer.c (pending_atimers):
4665 * blockinput.h: Don't include "atimer.h"; no longer needed.
4666 (interrupt_input_pending): Remove. All uses removed.
4667 pending_signals now counts both atimers and ordinary interrupts.
4668 This is less racy than having three separate pending-signal flags.
4669 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4671 Rename from their upper-case counterparts BLOCK_INPUT,
4672 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4673 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4674 This makes it easier to access volatile variables more accurately.
4675 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4676 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4677 that's more reliable if the code is buggy and sets
4678 interrupt_input_blocked to a negative value. All uses changed.
4679 * atimer.c (deliver_alarm_signal):
4680 Remove. No need to deliver this to the parent; any thread can
4681 handle this signal now. All uses replaced by underlying handler.
4682 * atimer.c (turn_on_atimers):
4683 * dispnew.c (handle_window_change_signal):
4684 * emacs.c (handle_danger_signal):
4685 * keyboard.c (kbd_buffer_get_event):
4686 Don't reestablish signal handler; not needed with sigaction.
4687 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4689 Rework to avoid unnecessary accesses to volatile variables.
4690 (UNBLOCK_INPUT_TO): Now a function.
4691 (totally_unblock_input, unblock_input): New decls.
4692 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4693 (init_data): Remove. Necessary stuff now done in init_signal.
4694 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4695 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4696 (fatal_error_code): Remove; no longer needed.
4697 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4698 it doesn't always backtrace. All uses changed. No need to reset
4699 signal to default, since sigaction and/or die does that for us now.
4700 Use emacs_raise (FOO), not kill (getpid (), FOO).
4701 (main): Check more-accurately whether we're dumping.
4702 Move fatal-error setup to sysdep.c
4703 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4704 * gtkutil.c (xg_get_file_name, xg_get_font):
4705 Remove no-longer-needed signal-mask manipulation.
4706 * keyboard.c, process.c (POLL_FOR_INPUT):
4707 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4708 * keyboard.c (read_avail_input): Remove.
4709 All uses replaced by gobble_input.
4710 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4711 (kbd_buffer_store_event_hold, gobble_input):
4712 (record_asynch_buffer_change) [USABLE_SIGIO]:
4713 (store_user_signal_events):
4714 No need to mess with signal mask.
4715 (gobble_input): If blocking input and there are terminals, simply
4716 set pending_signals to 1 and return. All hooks changed to not
4717 worry about whether input is blocked.
4718 (process_pending_signals): Clear pending_signals before processing
4719 them, in case a signal comes in while we're processing.
4720 By convention callers now test pending_signals before calling us.
4721 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4722 New functions, to support changes to blockinput.h.
4723 (handle_input_available_signal): Now extern.
4724 (reinvoke_input_signal): Remove. All uses replaced by
4726 (quit_count): Now volatile, since a signal handler uses it.
4727 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4728 All callers changed. Block SIGINT only if not already blocked.
4729 Clear sigmask reliably, even if Fsignal returns, which it can.
4730 Omit unnecessary accesses to volatile var.
4731 (quit_throw_to_read_char): No need to restore sigmask.
4732 * keyboard.c (gobble_input, handle_user_signal):
4733 * process.c (wait_reading_process_output):
4734 Call signal-handling code rather than killing ourselves.
4735 * lisp.h: Include <float.h>, for...
4736 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4737 (pending_signals): Now volatile.
4738 (syms_of_data): Now const if IEEE floating point.
4739 (handle_input_available_signal) [USABLE_SIGIO]:
4740 (terminate_due_to_signal, record_child_status_change): New decls.
4741 * process.c (create_process): Avoid disaster if memory is exhausted
4742 while we're processing a vfork, by tightening the critical section
4744 (send_process_frame, process_sent_to, handle_pipe_signal)
4745 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4747 (send_process): No need for setjmp/longjmp any more, since the
4748 SIGPIPE stuff is now gone. Instead, report an error if errno
4750 (record_child_status_change): Now extern. PID and W are now args.
4751 Return void, not bool. All callers changed.
4752 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4753 Remove. All uses removed. This bug should be fixed now in a
4755 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4756 and record the child status change directly. This avoids the
4757 need to futz with the signal mask.
4758 (process_fatal_action): Move here from emacs.c.
4759 (emacs_sigaction_flags): New function, containing
4760 much of what used to be in emacs_sigaction_init.
4761 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4762 caught by emacs, to make races less likely.
4763 (deliver_process_signal): Rename from handle_on_main_thread.
4765 (BACKTRACE_LIMIT_MAX): Now at top level.
4766 (thread_backtrace_buffer, threadback_backtrace_pointers):
4768 (deliver_thread_signal, deliver_fatal_thread_signal):
4769 New functions, for more-accurate delivery of thread-specific signals.
4770 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4771 (deliver_arith_signal): Handle in this thread, not
4772 in the main thread, since it's triggered by this thread.
4773 (maybe_fatal_sig): New function.
4774 (init_signals): New arg DUMPING so that we can be more accurate
4775 about whether we're dumping. Caller changed.
4776 Treat thread-specific signals differently from process-general signals.
4777 Block all signals while handling fatal error; that's safer.
4778 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4780 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4781 Ignore SIGPIPE unless batch.
4782 (emacs_backtrace): Output backtrace for the appropriate thread,
4783 which is not necessarily the main thread.
4784 * syssignal.h: Include <stdbool.h>.
4785 (emacs_raise): New macro.
4786 * xterm.c (x_connection_signal): Remove; no longer needed
4787 now that we use sigaction.
4788 (x_connection_closed): No need to mess with sigmask now.
4789 (x_initialize): No need to reset SIGPIPE handler here, since
4790 init_signals does this for us now.
4792 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4794 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4795 background rect may be larger (Bug#12245).
4797 2012-09-23 Chong Yidong <cyd@gnu.org>
4799 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4801 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4803 * .gdbinit: Just stop at fatal_error_backtrace.
4804 See Stefan Monnier's request in
4805 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4806 Remove no-longer-used query of system type.
4808 2012-09-22 Chong Yidong <cyd@gnu.org>
4810 * search.c (Freplace_match): Doc fix (Bug#12325).
4812 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4814 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4815 (Fline_end_position): Doc fix.
4817 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4819 2012-09-22 Chong Yidong <cyd@gnu.org>
4821 * dispextern.h (struct image_type): Add new slot, storing a type
4822 initialization function.
4824 * image.c (define_image_type): Call the image initializer function
4825 if it is defined. Arguments and return value changed.
4826 (valid_image_p, make_image): Callers changed.
4827 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4828 (gif_type, imagemagick_type, svg_type, gs_type):
4829 Add initialization functions.
4830 (Finit_image_library): Call lookup_image_type.
4831 (CHECK_LIB_AVAILABLE): Macro deleted.
4832 (lookup_image_type): Call define_image_type here, rather than via
4833 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4834 (syms_of_image): Move define_image_type calls for xbm_type and
4835 pbm_type to lookup_image_type.
4837 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4839 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4840 'idle_timers' from here ...
4841 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4842 lists, to avoid infloops when the timer does something stupid,
4843 like reinvoke itself with the same or smaller time-out.
4846 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4848 * window.c (Fsplit_window_internal): Handle only Qt value of
4849 Vwindow_combination_limit separately.
4850 (Qtemp_buffer_resize): New symbol.
4851 (Vwindow_combination_limit): New default value.
4854 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4856 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4857 the new overlay string. (Bug#10159)
4859 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4861 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4862 or that fprintf is async-signal-safe. POSIX doesn't require
4865 2012-09-22 Chong Yidong <cyd@gnu.org>
4867 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4870 2012-09-22 Kenichi Handa <handa@gnu.org>
4872 * composite.c (composition_reseat_it): Handle the case that a
4873 grapheme cluster is not covered by a single font (Bug#12352).
4875 2012-09-21 Chong Yidong <cyd@gnu.org>
4877 * image.c (define_image_type): Avoid adding duplicate types to
4878 image_types (Bug#12463). Suggested by Jörg Walter.
4880 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4882 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4883 (print_load_command_name): Add case LC_DATA_IN_CODE.
4884 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4886 2012-09-21 Glenn Morris <rgm@gnu.org>
4888 * eval.c (Frun_hook_with_args_until_success)
4889 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4891 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4893 * fileio.c (Ffile_selinux_context): Only call freecon when
4894 lgetfilecon succeeded.
4895 (Fset_file_selinux_context): Likewise. (Bug#12444)
4897 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4899 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4900 reordering, locate the cursor by calling set_cursor_from_row; if
4901 that fails, clear the desired glyph matrix before returning a
4902 failure indication to the caller. Fixes leaving garbled display
4903 when fast scrolling with a down-key. (Bug#12403)
4904 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4905 scrolling through multibyte text.
4907 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4909 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4910 calling mark_vectorlike since that's the one that marks the window.
4911 (mark_discard_killed_buffers): Mark the final cdr.
4912 * window.h (struct window): Move prev/next_buffers to the
4913 non-standard fields.
4914 * window.c (make_window): Initialize prev/next_buffers manually.
4916 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4918 Omit unused arg EXPECTED from socket hooks.
4919 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4920 * nsterm.m (ns_term_init):
4921 * termhooks.h (struct terminal.read_socket_hook):
4922 * w32inevt.c (w32_console_read_socket):
4923 * w32term.c (w32_read_socket):
4924 * xterm.c (XTread_socket):
4925 Omit unused arg EXPECTED. All callers changed.
4926 (store_user_signal_events): Return void, not int, since callers no
4927 longer care about the return value. All uses changed.
4929 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4931 * w32gui.h (XParseGeometry): Do not declare.
4933 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4935 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4936 Ignore 'expected'. See Eli Zaretskii in
4937 <http://bugs.gnu.org/12471#8> (last line).
4939 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4940 (XParseGeometry): Now static. Substitute extremal values for
4941 values that are out of range.
4943 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4945 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4947 * nsfns.m (XParseGeometry): Remove.
4948 (Fx_create_frame): Call x_set_offset to correctly interpret
4949 top_pos in geometry.
4951 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4952 (Fx_parse_geometry): If there is a space in string, call
4953 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4955 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4957 * search.c (scan_buffer): Use character positions in calls to
4958 region_cache_forward and region_cache_backward, not byte
4959 positions. (Bug#12196)
4961 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4962 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4964 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4965 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4966 emacs_blocked_malloc, now deleted.
4968 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4970 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4971 The workaround was for improving performance on Solaris 2.4, but
4972 is getting in the way now. Emacs will still work if someone is
4973 still running Solaris 2.4 in a museum somewhere; Sun dropped
4974 support for Solaris 2.4 in 2003.
4975 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4976 * process.c (create_process) [HAVE_WORKING_VFORK]:
4977 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4978 since Emacs no longer uses vfork on that platform.
4980 2012-09-17 Glenn Morris <rgm@gnu.org>
4982 * emacs.c: Use COPYRIGHT.
4984 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4986 Remove configure's --without-sync-input option (Bug#12450).
4987 When auditing signal-handling in preparation for cleaning it up,
4988 I found that SYNC_INPUT has race conditions and would be a real
4989 pain to fix. Since it's an undocumented and deprecated
4990 configure-time option, now seems like a good time to remove it.
4991 Also see <http://bugs.gnu.org/11080#16>.
4992 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4993 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4994 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4995 (malloc_hysteresis):
4996 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4997 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4998 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4999 (dont_register_blocks, bytes_used_when_reconsidered)
5000 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5001 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5002 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5003 Remove. All uses removed.
5004 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5005 implementation, one that depends on whether the new macro
5006 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5008 * atimer.c (run_timers, handle_alarm_signal):
5009 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5010 (handle_async_input, process_pending_signals)
5011 (handle_input_available_signal, init_keyboard):
5012 * nsterm.m (ns_read_socket):
5013 * process.c (wait_reading_process_output):
5014 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5015 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5017 * xterm.c (XTread_socket):
5019 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5020 * eval.c (handling_signal): Remove. All uses removed.
5021 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5022 All uses replaced with the SYNC_INPUT version.
5023 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5025 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5028 * font.c (Ffont_shape_gstring): Remove unused local.
5030 2012-09-16 Glenn Morris <rgm@gnu.org>
5032 * Makefile.in (clean): No longer run nextstep's clean.
5034 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5036 (ns-app): Move here from ns.mk, and simplify.
5037 (clean): Simplify nextstep entry.
5038 * ns.mk: Remove file.
5040 2012-09-17 Kenichi Handa <handa@gnu.org>
5042 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5043 not covert the last few charactes.
5045 2012-09-16 Kenichi Handa <handa@gnu.org>
5047 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5048 here, but just check the validity of glyphs in the glyph-string.
5050 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5052 * window.c (Fwindow_parameter, Fset_window_parameter):
5053 Accept any window as argument (Bug#12452).
5055 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5057 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5058 to ns_term_init to avoid memory leak.
5060 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5061 explicit retain/release.
5062 (ns_term_init): Only allow one display. Initialize outerpool and
5065 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5067 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5068 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5069 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5070 the Microsoft problem in a different way, by altering ../nt/config.nt.
5072 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5087 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5088 by lisp.h. This completes removal of setjmp.h inclusion
5089 erroneously announced in the previous commit. (Bug#12446)
5091 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5094 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5095 not defined as a macro. The latter happens on MS-Windows.
5098 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5100 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5101 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5102 Some instances of '#include <setjmp.h>' removed, if the
5103 only reason for the instance was because "lisp.h" was included.
5104 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5105 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5106 and _longjmp with the new symbols. Emacs already uses _setjmp if
5107 available, so this change affects only POSIXish hosts that have
5108 sigsetjmp but not _setjmp, such as some versions of Solaris and
5109 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5110 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5111 (png_load_body) [HAVE_PNG]:
5112 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5113 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5114 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5115 since PNG requires jmp_buf. This is the only exception to the
5116 general rule that we now use sys_setjmp and sys_longjmp.
5117 This exception is OK since this code does not change the signal
5118 mask or longjmp out of a signal handler.
5120 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5122 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5123 Include "syssignal.h", for 'main_thread'.
5125 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5127 Avoid out-of-range marker position (Bug#12426).
5128 * insdel.c (replace_range, replace_range_2):
5129 Adjust markers before overlays, as suggested by comments.
5130 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5131 Remove redundant check before calling offset_intervals.
5133 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5135 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5136 current buffer (Bug#12387).
5138 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5140 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5142 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5144 Use a more backwards-compatible timer format (Bug#12430).
5145 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5146 vector element, not from the 4th, since PSECS is now at the end.
5147 (Fcurrent_idle_time): Doc fix.
5149 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5151 Function to mark objects and remove killed buffers at once.
5152 * alloc.c (discard_killed_buffers): Rename to ...
5153 (mark_discard_killed buffers) ... new name. Add marking
5154 of remaining objects. Fix comment. Adjust users.
5155 (mark_object): Do not touch frame buffer lists here.
5156 * frame.c (delete_frame): Reset frame buffer lists here.
5158 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5160 Better workaround for GNOME bug when --enable-gcc-warnings.
5161 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5162 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5163 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5165 Simplify SIGIO usage (Bug#12408).
5166 The code that dealt with SIGIO was crufty and confusing, e.g., it
5167 played tricks like "#undef SIGIO" but these tricks were not used
5168 consistently. Simplify mostly by not #undeffing standard symbols,
5169 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5170 or not as we please) rather than "defined SIGIO" (standard symbol
5171 that we probably shouldn't #undef).
5172 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5173 Modules that need it can include it.
5174 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5175 * dispextern.h (ignore_sigio): New decl.
5176 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5177 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5178 * emacs.c (shut_down_emacs):
5179 * keyboard.c (kbd_buffer_store_event_hold):
5180 Use ignore_sigio rather than invoking 'signal' directly.
5181 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5183 (FIONREAD, SIGIO): Do not #undef.
5184 (tty_read_avail_input): Use #error rather than a syntax error.
5185 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5186 for I_PIPE, used by SETUP_SLAVE_PTY.
5187 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5188 * sysdep.c (croak): Remove; no longer needed. This bit of
5189 temporary code, with Fred N. Fish's comment that it's temporary,
5190 has been in Emacs since at least 1992!
5191 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5192 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5193 * syssignal.h (croak): Remove decl.
5194 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5195 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5196 now that we're termios-only.
5197 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5198 * term.c (dissociate_if_controlling_tty): Use #error rather than
5201 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5202 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5203 to work around GNOME bug 683906.
5204 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5205 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5206 This works around GCC bug 54561.
5208 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5210 More fixes for 'volatile' and setjmp/longjmp.
5211 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5212 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5213 (png_load_body) [HAVE_PNG]:
5214 (jpeg_load_body) [HAVE_JPEG]:
5215 New function, with most of the old parent function's body.
5216 (png_load) [HAVE_PNG]:
5217 (jpeg_load) [HAVE_JPEG]:
5218 Invoke the new function, to avoid longjmp munging our locals.
5219 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5220 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5221 longjmp is passed 2, as the C standard doesn't guarantee this.
5222 Instead, store the failure code into mgr->failure_code.
5224 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5226 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5227 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5228 (syms_of_keyboard): Remove support for unread-command-char.
5230 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5232 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5233 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5234 violation. (Bug#12426)
5236 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5238 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5240 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5242 * eval.c: Add `inhibit-debugger'.
5243 (Qinhibit_debugger): New symbol.
5244 (call_debugger): Bind it instead of Qdebug_on_error.
5245 (maybe_call_debugger): Test Vinhibit_debugger.
5246 (syms_of_eval): Define inhibit-debugger.
5247 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5248 (syms_of_xdisp): Remove inhibit-debug-on-message.
5250 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5252 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5253 If a nonvolatile local variable is written before a _longjmp to
5254 the frame containing the variable, and is read after the _longjmp,
5255 the value read is indeterminate. Some local variables of type
5256 'struct handler' and 'struct catchtag' are used in this way, so
5257 mark each of their slots as volatile if the slot can be set before
5258 _longjmp and read afterwards.
5259 * lisp.h (struct handler): var and chosen_clause are now volatile.
5260 (struct catchtag): val, next, and pdlcount are now volatile.
5262 * bidi.c (bidi_push_it, bidi_pop_it):
5263 * fns.c (copy_hash_table):
5264 * image.c (define_image_type):
5265 * keyboard.c (kbd_buffer_store_event_hold):
5266 * process.c (Fprocess_send_eof):
5267 * xfaces.c (x_create_gc) [HAVE_NS]:
5268 * xgselect.c (xg_select):
5269 Prefer assignment to memcpy when either will do.
5271 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5272 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5273 time an item is removed. No need to mark this function 'inline';
5274 the compiler knows better than we do.
5276 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5278 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5279 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5280 to change_frame_size (Bug#12388).
5281 (windowDidResize:): Pass YES to updateFrameSize.
5283 * nsterm.h: Add delay parameter to updateFrameSize.
5285 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5287 Discard killed buffers from deleted window and frame objects.
5288 This reduces an amount of references to killed buffers and
5289 helps GC to reclaim them faster.
5290 * alloc.c (discard_killed_buffers): New function.
5291 (mark_object): Use it for deleted windows and frames.
5292 (mark_object): If symbol's value is set up for a killed buffer
5293 or deleted frame, restore its global binding.
5294 * data.c (swap_in_global_binding): Add GC notice.
5295 (swap_in_symval_forwarding): Use convenient set_blv_where.
5296 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5297 * window.h: ... to here.
5299 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5301 Convenient macro to check whether the buffer is live.
5302 * buffer.h (BUFFER_LIVE_P): New macro.
5303 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5304 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5306 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5308 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5309 composition cases (Bug#12364).
5311 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5312 overhang of succeeding glyphs overlapping box cursor.
5314 * w32term.c (x_draw_glyph_string): Likewise.
5316 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5318 Simplify, document, and port floating-point (Bug#12381).
5319 The porting part of this patch fixes bugs on non-IEEE platforms
5320 with frexp, ldexp, logb.
5321 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5323 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5324 support, by removing commented-out code and briefly listing the
5325 C89 functions excluded. The commented-out stuff was confusing
5326 maintenance, e.g., we thought we needed cbrt but it was commented out.
5327 (logb): Remove decl; no longer needed.
5328 (isfinite): New macro, if not already supplied.
5329 (isnan): Don't replace any existing macro.
5330 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5331 are present on all C89 platforms.
5332 (Ffrexp): Do not special-case zero, as frexp does the right thing
5334 (Flogb): Do not use logb, as it doesn't have the desired meaning
5335 on hosts that use non-base-2 floating point. Instead, stick with
5336 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5337 frexp, to avoid getting an unspecified result.
5339 * xdisp.c (Qinhibit_debug_on_message): Now static.
5341 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5343 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5344 NSBezierPath (Bug#12131).
5346 2012-09-10 Chong Yidong <cyd@gnu.org>
5348 * fns.c (Fdelq, Fdelete): Doc fix.
5350 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5352 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5353 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5355 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5357 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5358 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5361 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5363 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5364 left fringe if the window has a left margin. This avoids leaving
5365 traces of the cursor because its leftmost pixel is not drawn over.
5367 * dispnew.c (update_window_line): When the left margin area of a
5368 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5369 that screen line. (Bug#12277)
5371 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5373 Assume C89 or later for math functions (Bug#12381).
5374 This simplifies the code, and makes it a bit smaller and faster,
5375 and (most important) makes it easier to clean up signal handling
5376 since we can stop worring about floating-point exceptions in
5377 library code. That was a problem before C89, but the problem
5378 went away many years ago on all practical Emacs targets.
5379 * data.c, image.c, lread.c, print.c:
5380 Don't include <math.h>; no longer needed.
5381 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5382 might be autoconfigured, as that never happens.
5384 * doprnt.c (DBL_MAX_10_EXP):
5385 * print.c (DBL_DIG):
5386 Remove. C89 or later always defines these.
5387 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5388 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5389 (arith_error, domain_error, domain_error2):
5390 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5391 no longer needed -- we simply return what C returns. All uses removed.
5392 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5394 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5395 Remove. All uses expanded, as these macros are no longer used
5396 more than once and are now more trouble than they're worth.
5397 (Ftan): Use tan, not sin / cos.
5398 (Flogb): Assume C89 frexp.
5399 (fmod_float): Assume C89 fmod.
5400 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5401 (init_floatfns): Remove. All uses removed.
5403 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5405 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5406 compositeToPoint for OSX < 10.6 (Bug#12390).
5408 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5410 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5411 This produces more-accurate results.
5413 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5415 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5416 changes (Bug#12088).
5418 2012-09-08 Chong Yidong <cyd@gnu.org>
5420 * syntax.c (Fstring_to_syntax): Doc fix.
5422 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5424 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5425 in the internal border.
5426 (x_set_window_size): Remove static variables and their usage.
5427 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5428 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5429 Remove fringe/internal border adjustment (Bug#11052).
5430 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5431 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5432 (ns_fix_rect_ibw): Remove.
5433 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5434 (ns_dumpglyphs_box_or_relief): Ditto.
5435 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5437 (ns_dumpglyphs_image): Ditto.
5438 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5440 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5441 their usage. Add fringe_extended_p and its use as in other terms.
5442 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5443 scroll bar was removed.
5444 (updateFrameSize): New function.
5445 (windowDidResize): Move code to updateFrameSize and call it.
5447 * nsterm.h (EmacsView): Add updateFrameSize.
5449 2012-09-07 Chong Yidong <cyd@gnu.org>
5451 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5453 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5455 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5457 More signal-handler cleanup (Bug#12327).
5458 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5459 Problem introduced when merging patches. Noted by Eli Zaretskii in
5460 <http://bugs.gnu.org/12327#67>.
5461 * floatfns.c: Comment fix.
5462 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5463 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5464 and anyway the declaration is harmless even if SIGDANGER is not defined.
5465 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5466 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5467 source files not surprisingly expected syssignal.h to define, or
5468 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5469 Include <sys/ioctl.h>, for FIONREAD.
5470 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5471 This eliminates a problem whereby other files mysteriously had
5472 to include "syssignal.h" before including "systty.h" if they
5473 wanted to use "#ifdef SIGIO".
5475 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5477 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5479 * w32.c (sigemptyset): Empty the set.
5480 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5482 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5484 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5486 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5487 (mark_object): Likewise for frame objects.
5489 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5491 * syssignal.h (handle_on_main_thread): Always declare,
5492 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5493 This ports to platforms without HAVE_PTHREAD.
5495 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5497 Signal-handler cleanup (Bug#12327).
5498 Emacs's signal handlers were written in the old 4.2BSD style with
5499 sigblock and sigmask and so forth, and this led to some
5500 inefficiencies and confusion. Rewrite these to use
5501 pthread_sigmask etc. without copying signal sets around. Also,
5502 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5503 'signal', and instead use functions that do not attempt to take
5504 over the system name space. This patch causes Emacs's text
5505 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5506 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5507 Do not include <signal.h> or "syssignal.h", as these
5508 modules do not use signals.
5509 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5510 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5511 Do not include <signal.h>, as "syssignal.h" does that for us now.
5512 * atimer.c (sigmask_atimers): New function.
5513 (block_atimers, unblock_atimers): New functions,
5514 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5516 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5517 no longer needed here.
5518 * emacs.c (main): Inspect existing signal handler with sigaction,
5519 so that there's no need to block and unblock SIGHUP.
5520 * sysdep.c (struct save_signal): New member 'action', replacing
5521 old member 'handler'.
5522 (save_signal_handlers, restore_signal_handlers):
5523 Use sigaction instead of 'signal' to save and restore.
5524 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5525 New function. All users of 'signal' modified to use set_sighandler
5526 if they're writeonly, and to use sys_signal if they're read+write.
5527 (emacs_sigaction_init, forwarded_signal): New functions.
5528 (sys_signal): Remove. All uses replaced by calls to sigaction
5529 and emacs_sigaction_init, or by direct calls to 'signal'.
5530 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5531 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5532 all uses replaced by pthread_sigmask etc. calls.
5533 * syssignal.h: Include <signal.h>.
5534 (emacs_sigaction_init, forwarded_signal): New decls.
5535 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5536 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5537 (sigmask, sys_sigmask): Remove; no longer needed.
5538 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5539 (sigblock, sigunblock, sigfree):
5540 (sigsetmask) [!defined sigsetmask]:
5541 Remove. All uses replaced by pthread_sigmask.
5542 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5543 no longer need to be replaced, and its typical old uses
5544 are now done via emacs_sigaction_init and sigaction.
5545 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5546 (sys_sigdel): Remove; unused.
5547 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5549 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5551 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5552 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5554 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5556 Explicitly mark buffer_defaults and buffer_local_symbols.
5557 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5558 mark_local_symbols here.
5559 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5560 since special buffers aren't marked here any more.
5561 (allocate_buffer): Chain new buffer with all_buffers here...
5562 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5564 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5565 (syms_of_buffer): Remove staticpro of the above.
5566 (init_buffer_once): Set names for buffer_defaults and
5567 buffer_local_symbols.
5569 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5571 Use bool for booleans in font-related modules.
5572 * font.c (font_intern_prop, font_style_to_value)
5573 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5574 (generate_otf_features, font_check_otf_features, font_check_otf)
5575 (font_match_p, font_list_entities, font_at):
5576 * fontset.c (fontset_id_valid_p, reorder_font_vector
5577 (fontset_find_font, Fset_fontset_font)
5578 (face_suitable_for_char_p) [0]:
5579 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5580 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5581 (m17n_flt_initialized, ftfont_shape_by_flt):
5582 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5583 * nsfont.m (nsfont_draw):
5584 * w32font.c (w32font_draw):
5585 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5586 Use bool for booleans.
5587 * font.h: Adjust to above API changes.
5588 (struct font, struct font_driver, struct font_driver_list):
5589 Use bool for booleans.
5590 (struct font): Remove useless member encoding_type.
5592 * fontset.c, xftfont.c: Omit unnecessary static decls.
5594 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5596 * alloc.c (mark_object): Revert window marking code
5597 since it's unsafe for the Fset_window_configuration.
5599 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5601 Fix race conditions with signal handlers and errno (Bug#12327).
5602 Be more systematic about preserving errno whenever a signal
5603 handler returns, even if it's not in the main thread. Do this by
5604 renaming signal handlers to distinguish between signal delivery
5605 and signal handling. All uses changed.
5606 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5607 * data.c (deliver_arith_signal): Rename from arith_error.
5608 * dispnew.c (deliver_window_change_signal): Rename from
5609 window_change_signal.
5610 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5611 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5612 * keyboard.c (deliver_input_available_signal): Rename from
5613 input_available_signal.
5614 (deliver_user_signal): Rename from handle_user_signal.
5615 (deliver_interrupt_signal): Rename from interrupt_signal.
5616 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5617 (deliver_child_signal): Rename from sigchld_handler.
5618 * atimer.c (handle_alarm_signal):
5619 * data.c (handle_arith_signal):
5620 * dispnew.c (handle_window_change_signal):
5621 * emacs.c (handle_fatal_signal, handle_danger_signal):
5622 * keyboard.c (handle_input_available_signal):
5623 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5624 * process.c (handle_pipe_signal, handle_child_signal):
5625 New functions, with the actual signal-handling code taken from the
5626 original respective signal handlers, sans the sporadic attempts to
5627 preserve errno, since that's now done by handle_on_main_thread.
5628 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5629 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5630 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5632 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5633 Move initialization of main_thread to sysdep.c's init_signals.
5634 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5635 our usage, and simplifies the mainline code.
5636 (record_child_status_change): New static function, as a helper
5637 for handle_child_signal, and with most of the old child handler's
5639 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5640 (handle_child_signal): Use the above.
5641 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5642 Moved here from emacs.c.
5643 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5644 code moved here from emacs.c's main function.
5645 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5646 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5647 This lets callers save and restore errno properly.
5649 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5651 Remove redundant or unused things here and there.
5652 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5653 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5654 * editfns.c (Fcompare_buffer_substrings): Likewise.
5655 * frame.h (struct terminal, struct font_driver_list):
5656 Remove redundant declarations.
5657 * window.h (Qleft, Qright): Likewise.
5659 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5661 Do not mark objects from deleted buffers, windows and frames.
5662 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5663 (mark_object): Likewise for windows and frames.
5665 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5667 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5668 buffer_defaults and buffer_local_symbols as valid objects.
5669 Return special value to denote them.
5671 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5673 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5674 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5675 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5676 (file_name_absolute_p, Fsubstitute_in_file_name):
5677 (check_executable, check_writable, Ffile_accessible_directory_p)
5678 (Fset_file_selinux_context, Fdefault_file_modes)
5679 (Finsert_file_contents, choose_write_coding_system)
5680 (Fwrite_region, build_annotations, a_write, e_write)
5682 * filelock.c (boot_time_initialized, get_boot_time)
5683 (get_boot_time_1, lock_file_1, within_one_second):
5684 * floatfns.c (in_float):
5685 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5686 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5687 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5688 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5689 * window.c (compare_window_configurations):
5690 Use bool for booleans.
5691 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5692 (Fdefault_file_modes): Now mode_t, not int, for modes.
5693 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5694 (internal_delete_file): Now returns void, not a (boolean) int,
5695 since nobody was looking at the return value.
5696 * lisp.h, window.h: Adjust to above API changes.
5698 * xdisp.c (set_message): Simplify and reindent last change.
5700 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5702 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5704 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5706 * eval.c (call_debugger): Make the function non-static so that we
5707 can call it from set_message.
5709 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5710 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5712 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5714 Give more-useful info on a fatal error (Bug#12328).
5715 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5716 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5717 of doing the work ourselves.
5718 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5719 do most of the work.
5720 (fatal_error_backtrace): New function, taken from the guts
5721 of the old fatal_error_signal, but with a new option to output
5723 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5724 info about the signal than just its number.
5725 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5726 * sysdep.c: Include <execinfo.h>
5727 (emacs_backtrace): New function, taken partly from the previous
5728 code of the 'die' function.
5729 (emacs_abort): Call fatal_error_backtrace rather than abort.
5731 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5733 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5734 eager (load-time) macro-expansion.
5735 * lisp.mk (lisp): Add macroexp.
5737 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5739 Simplify redefinition of 'abort' (Bug#12316).
5740 Do not try to redefine the 'abort' function. Instead, redo
5741 the code so that it calls 'emacs_abort' rather than 'abort'.
5742 This removes the need for the NO_ABORT configure-time macro
5743 and makes it easier to change the abort code to do a backtrace.
5744 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5745 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5746 Remove; sysdep.c's emacs_abort now takes its place.
5747 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5748 'abort' changed to use 'emacs_abort'.
5749 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5750 (abort) [!defined abort]: Rename to ...
5751 (emacs_abort): ... new name.
5752 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5753 the place of the old 'abort' in emacs.c.
5754 * w32.c, w32fns.c (abort): Do not #undef.
5755 * w32.c (emacs_abort): Rename from w32_abort.
5757 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5759 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5760 offsets[j].dv, since the y axis of the screen coordinates points
5761 down, while the y axis of the font definition coordinates points
5762 up. This fixes display of Arabic diacritics such as KASRA and
5763 KASRATAN. (Bug#11860)
5765 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5767 Be more systematic about _setjmp vs setjmp.
5768 * alloc.c (test_setjmp, mark_stack):
5769 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5770 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5771 (png_load, my_error_exit, jpeg_load):
5772 * process.c (send_process_trap, send_process):
5773 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5774 The underscored versions are up to 30x faster on some hosts.
5775 Formerly, the code used setjmp+longjmp sometimes and
5776 _setjmp+_longjmp at other times, with no particular reason to
5777 prefer setjmp+longjmp.
5779 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5781 Fix minor problem found by static checking.
5782 * buffer.c (Fdelete_all_overlays): Return nil.
5784 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5786 * buffer.c (Fdelete_all_overlays): New function.
5788 2012-09-03 Chong Yidong <cyd@gnu.org>
5790 * gtkutil.c: Add extern decl for Qxft.
5792 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5794 * emacs.c, eval.c: Use bool for boolean.
5795 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5796 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5797 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5798 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

5801 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5802 (maybe_call_debugger, Fbacktrace):
5803 * process.c (read_process_output, exec_sentinel):
5804 Use bool for booleans.
5805 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5806 All callers changed.
5807 * eval.c (interactive_p): Omit always-true boolean argument
5808 EXCLUDE_SUBRS_P. All callers changed.
5809 * dispextern.h, lisp.h: Reflect above API changes.
5810 * firstfile.c (dummy): Use the address of 'main', whose signature
5811 won't change, instead of the address of 'initialize', whose
5812 signature just changed from int to bool.
5813 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5814 * msdos.c (fatal_error_in_progress): ... from here.
5815 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5817 (redisplay_internal, unwind_redisplay): Simply clear
5818 REDISPLAYING_P when unwinding, instead of saving its previous,
5819 always-false value and then restoring it.
5821 Clean up some extern decls.
5822 Mostly, this hoists extern decls out of .c files and into .h files.
5823 That way, we're more likely to catch errors if the interfaces change.
5824 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5825 declare xg_mark_data.
5826 * dispextern.h (x_frame_parm_handlers):
5828 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5829 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5830 (Qultra_bold, Qoblique, Qitalic):
5831 Move extern decl here from .c file.
5832 * alloc.c (xg_mark_data) [USE_GTK]:
5834 * eval.c (Qlexical_binding):
5835 * fns.c (time) [!HAVE_UNISTD_H]:

5844 * xfont.c (x_clear_errors):
5845 * xterm.c (x_frame_parm_handlers):
5846 Remove now-redundant extern decls.
5847 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5848 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5850 * xfaces.c: Remove unnecessary static decls.
5851 * xterm.c (updating_frame): Remove decl of nonexistent object.
5853 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5854 when building globals.h, as the objects that are not built on
5855 this host are not needed to compile C files on this host.
5857 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5859 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5861 * frame.h: Add missing prototype for x_wm_set_size_hint.
5863 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5867 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5868 (Fsubstitute_command_keys):

5887 * keyboard.c (decode_timer):
5888 Use bool for boolean.
5889 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5890 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5892 2012-09-02 Chong Yidong <cyd@gnu.org>
5894 * keymap.c (push_key_description): Print M-TAB as C-M-i
5897 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5899 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5900 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5901 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5905 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5907 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5909 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5910 more than one grapheme cluster passed to the shaper: compute the
5911 offset adjustment values separately for each cluster. (Bug#11860)
5913 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5914 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5915 about implicit conversions from integer to pointer.
5917 2012-09-01 Daniel Colascione <dancol@dancol.org>

6234 Special MEM_TYPE_SPARE to denote reserved memory.
6235 * alloc.c (enum mem_type): New memory type.
6236 (refill_memory_reserve): Use new type for spare memory.

6270 * character.h, charset.h: Adjust to match previous changes.
6271 * character.h (char_printable_p): Remove decl of nonexistent function.
6272 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6273 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6274 are all boolean, so make them single-bit bitfields.
6276 * lisp.h (ASET): Remove attempt to detect side effects.
6277 It was meant to be temporary and it often doesn't work,
6278 because when IDX has side effects the behavior of IDX==IDX
6279 is undefined. See Stefan Monnier in
6280 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6282 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6285 (FUNCTIONP): Use it.
6286 * eval.c (Ffunctionp): Use it.
6288 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6290 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6291 as that's faster and simpler than static storage. Don't bother
6292 with the g_main_context_query overhead if g_main_context_pending
6293 says no events are pending.
6294 (gfds, gfds_size): Remove these static vars.
6295 (xgselect_initialize): Remove; no longer needed.
6296 All uses and decls removed.
6298 * emacs.c (fatal_error_signal_hook): Remove.
6299 All uses removed. This leftover from old code was always 0.

6326 Use bool for booleans, instead of int.
6327 * lisp.h, process.h: Adjust prototypes to match above changes.
6328 * callint.c (Fcall_interactively): Don't assume the mark's
6329 offset fits in 'int'.

6342 Use bool for booleans, instead of int.
6343 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6344 since the 1-or-0 return value is always ignored anyway.
6345 (mmap_initialized_p):
6346 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6347 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6349 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6351 * bidi.c: Use bool for boolean.
6352 This is a bit more readable, and makes the text segment of bidi.o
6353 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6354 Presumably it's faster too.

6376 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6378 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6379 compile time tests instead of run time tests on systems that do
6381 (FRAME_MAC_P): Remove leftover from deleted code.

6388 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6390 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6391 Otherwise, the compiler complains about (A?B:C) where B is void
6392 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6393 (fontset_add): Return void, for FONTSET_ADD.
6395 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6397 * alloc.c: Use bool for booleans.
6398 (gc_in_progress, abort_on_gc)
6399 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6400 (dont_register_blocks) [GC_MALLOC_CHECK]:
6401 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6402 (check_string_bytes, make_specified_string, memory_full)
6403 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6404 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6405 (mark_stack, valid_pointer_p, make_pure_string)
6406 (Fgarbage_collect, survives_gc_p, gc_sweep):
6407 Use bool for booleans, instead of int.
6408 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6409 Remove unused local.
6410 * alloc.c (PURE_POINTER_P):
6411 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6412 * editfns.c (Fformat):
6413 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)

6416 * lisp.h (suppress_checking, push_message, survives_gc_p)
6417 (make_pure_string, gc_in_progress, abort_on_gc):
6418 * lread.c (readchar, read1):
6419 * print.c (Fprin1_to_string):
6420 * xdisp.c (push_message):
6421 Use bool for booleans affected directly or indirectly by
6424 Make recently-introduced setters macros.
6425 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6426 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6427 (set_fontset_default, set_fontset_fallback): Rename from their
6428 upper-case counterparts, and make them functions rather than macros.
6429 This is more consistent with the other recently-introduced setters.
6430 These don't need to be inline, since they're local.
6432 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6434 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6435 the loop (Bug#12247).
6437 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6439 * lisp.h (vcopy): Use memcpy rather than our own loop.
6440 This fixes a performance regression introduced by the recent
6441 addition of vcopy. This means 'vcopy' will need to be modified
6442 for a copying collector, but that's OK. Also, tighten the
6443 checking in the assertion.
6445 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6447 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6448 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6449 non-base glyph for the width of the base character, according to
6450 what x_draw_composite_glyph_string_foreground expects.
6451 Generate WADJUST value according to composition_gstring_width's
6452 expectations, to produce correct width of the composed character.
6453 Reverse the sign of the DU offset produced by ScriptPlace.
6455 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6457 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6459 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6461 Avoid direct writes to contents member of struct Lisp_Vector.
6462 * lisp.h (vcopy): New function to copy data into vector.
6463 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6464 * fns.c (Ffillarray): Use ASET.
6465 * keyboard.c (timer_check_2): Use AREF and ASET.
6466 (append_tool_bar_item, Frecent_keys): Use vcopy.
6467 * lread.c (read_vector): Use ASET.
6468 * msdos.c (Frecent_doskeys): Use vcopy.
6469 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6470 (Finternal_merge_in_global_face): Use ASET and vcopy.

6476 the position of its buffer's point.
6477 (Fset_window_point): For the selected window always go in its
6478 buffer to the specified position.
6480 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6482 Setter macros for fontsets.
6483 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6484 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6485 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6488 2012-08-20 Glenn Morris <rgm@gnu.org>
6490 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6491 Don't assume that `ln -f' works.
6493 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6495 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6496 and later about non-assignments with no effect. See discussion at
6497 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6500 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6502 Inline setter functions for Lisp_Objects slots of struct specbinding.
6503 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6506 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6508 * window.c (select_window): Always make selected window's buffer
6511 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6513 Use AREF and ASET for docstrings of category tables.
6514 * category.h (CATEGORY_DOCSTRING): Use AREF.
6515 (SET_CATEGORY_DOCSTRING): Use ASET.
6516 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6518 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6520 Inline setter functions for hash table members.
6521 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6522 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6523 (set_hash_key_and_value, set_hash_index, set_hash_next)
6524 (set_hash_hash): New functions.
6525 * charset.c, fns.c: Adjust users.
6527 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6529 Inline getter and setter functions for per-buffer values.
6530 * buffer.h (per_buffer_default, set_per_buffer_default)
6531 (per_buffer_value, set_per_buffer_value): New functions.
6532 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6533 * buffer.c, data.c: Adjust users.
6535 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6537 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6539 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6541 Rely on <config.h> + <unistd.h> to declare 'environ',
6542 as gnulib does this if the system doesn't.
6543 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6544 Remove declaration. MS-Windows declares it on stdlib.h which is
6545 included by conf_post.h.
6546 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6547 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6548 * vm-limit.c: Include <unistd.h>, for 'environ'.
6550 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6551 (start_of_data): Remove decl; mem-limits.h provides it.
6553 * xdisp.c (handle_invisible_prop): Make it a bit faster
6554 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6556 2012-08-19 Chong Yidong <cyd@gnu.org>
6558 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6561 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

6566 * data.c (set_internal): Don't use set_blv_found.
6567 (Fkill_local_variable): Likewise.
6569 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6571 * nsfont.m (ns_ascii_average_width): Ensure the string
6572 ascii_printable is initialized with a null-terminated character
6573 array. Otherwise, it can contain undesired extra characters.
6575 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6577 port new setting code to Sun C 5.8 2005/10/13
6578 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6579 Return void, not Lisp_Object. Otherwise, the compiler
6580 complains about (A?B:C) where B is void and C is Lisp_Object
6581 when compiling CHAR_TABLE_SET, due to the recent change to
6582 the API of sub_char_table_set_contents.
6584 2012-08-18 Chong Yidong <cyd@gnu.org>
6586 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6587 for the string case (Bug#3874).

6742 The old version was confusing because it used the same name
6743 'parent' for two different things.

7414 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7415 * w32.c (init_environment): Change the default values of many
7416 environment variables in dflt_envvars[] to NULL, to avoid pushing
7417 them into environment when they were not already defined.
7418 Remove the code that deletes site-lisp subdirectories from the default
7419 value of EMACSLOADPATH, as it is no longer needed.
7420 (check_windows_init_file): Now external, not static.
7421 Use Vload_path as is, without adding anything, as this function is now
7422 called when Vload_path is already set up.
7424 * w32.h (check_windows_init_file): Add prototype.
7426 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7433 installation tree, as appropriate.
7435 * callproc.c (init_callproc_1): Call decode_env_path instead of
7436 doing its equivalent by hand.

7438 the code that sets Vexec_path run on MS-Windows.
7440 * lread.c (init_lread): Add comments to #ifdef's.
7442 * msdos.c (dos_set_window_size, IT_update_begin)

7454 Remove unnecessary casts involving pointers.
7455 These casts are no longer needed now that we assume C89 or later,

7468 (x_get_window_property, x_get_window_property_as_lisp_data):
7469 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7470 Remove unnecessary pointer casts.
7471 * alloc.c (record_xmalloc): New function.
7472 * lisp.h (record_xmalloc): New decl.
7473 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7474 more like a function. This is because the pointer cast is not
7475 needed. All uses changed.
7476 * print.c (print_string, print_error_message): Avoid length recalc.
7478 Improve fix for macroexp crash with debugging (Bug#12118).
7479 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7480 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7481 not supposed to be invoked from the garbage collector.
7482 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7483 (gc_aset): New function, which is like ASET but can be
7484 used in the garbage collector.
7485 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7500 headers (most versions of MinGW w32api don't).
7501 (get_security_info, create_symbolic_link)
7502 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

7513 with addition of handling of symlinks and support for 'lstat'.
7514 If possible, get file's attributes and security information by
7515 handle, not by name. Produce S_IFLNK bit for symlinks, when
7516 called from 'lstat'.
7517 (stat, lstat): New functions, call 'stat_worker'.
7518 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7519 symlinks when the underlying filesystem supports them.
7521 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7523 Fix macroexp crash on Windows with debugging (Bug#12118).
7524 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7525 checking subscripts; problem introduced with the recent
7526 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7527 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7528 since it's used in non-static inline functions now.
7530 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7531 Don't assume buffer size fits in 'int'. Remove unused local.

7548 * category.c (CATEGORY_INLINE):
7549 * character.c (CHARACTER_INLINE):
7550 * charset.c (CHARSET_INLINE):
7551 * composite.c (COMPOSITE_INLINE):
7552 * dispnew.c (DISPEXTERN_INLINE):
7553 * sysdep.c (SYSTIME_INLINE):
7554 Define to EXTERN_INLINE, so that the corresponding functions
7555 are compiled into code.
7556 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7557 (INLINE_HEADER_END): New macros.
7558 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7578 hard-coding the path separator.
7580 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7582 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7583 This how ASET and AREF are supposed to work, and makes
7584 it easier to think about future improvements. See
7585 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7586 * charset.h (set_charset_attr): New function.

8078 the fix for 12036 would have avoided some of the problems noted in
8079 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8080 would have been more obvious.

8090 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8091 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8092 not be usable in #if. This simplifies things.
8094 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8096 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8103 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8104 Adjust to changes in lisp.h and emacs.c, by using

8114 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8115 (xreload, hook-run, hookpost-run): Remove.
8116 * emacs.c: Include <verify.h>.
8117 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8118 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8120 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8121 (gdb_USE_LSB_TAG): New enum constants.
8122 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8123 Also define these as enum constants, so they're visible to GDB.

9009 (menu_separator_name_p):

9011 Prefer memcmp to strncmp when either will do.
9012 * nsterm.m: Include <ftoastr.h>.
9014 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9015 Prefer snprintf to strncpy.
9016 * nsterm.m (ns_term_init):
9017 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9018 * nsterm.m (ns_term_init):
9019 Avoid the need for strncpy, by using build_string or
9020 make_unibyte_string directly. Use dtoastr, not snprintf.
9021 * process.c (Fmake_network_process): Diagnose service names that
9022 are too long, rather than silently truncating them or creating
9023 non-null-terminated names.
9024 (Fnetwork_interface_info): Likewise, for interface names.

9053 Optimize pure C strings initialization.
9054 * lisp.h (make_pure_string): Fix prototype.
9055 (build_pure_c_string): New function, defined as static inline. This
9056 provides a better opportunity to optimize away calls to strlen when
9057 the function is called with compile-time constant argument.
9058 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9059 argument, adjust users accordingly. Use build_pure_c_string where
9061 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9062 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9063 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9065 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9067 Avoid calls to strlen in miscellaneous functions.
9068 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9069 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.

9074 Avoid calls to strlen in path processing functions.
9075 * fileio.c (file_name_as_directory): Add comment. Change to add
9076 srclen argument and return the length of result. Adjust users

9080 Adjust users accordingly.
9081 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9083 2012-07-10 Glenn Morris <rgm@gnu.org>

9090 * s/gnu.h (DATA_START): Move definitions to configure.
9092 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9093 We include usg5-4-common.h, which defines them both.
9095 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9096 O_RDONLY already includes it).
9098 Stop ns builds setting the EMACSLOADPATH environment variable.
9099 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9100 Now it does not set EMACSLOADPATH, just returns the load-path string.
9101 * nsterm.h: Update accordingly.
9102 * lread.c [HAVE_NS]: Include nsterm.h.
9103 (init_lread) [HAVE_NS]: Use ns_load_path.

9106 2012-07-09 Glenn Morris <rgm@gnu.org>
9108 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9109 since the included bsd-common.h does so.
9111 Stop ns builds setting the EMACSPATH environment variable.
9112 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9113 (ns_init_paths): Do not set EMACSPATH.
9114 * nsterm.h (ns_exec_path): Add it.
9115 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9118 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9120 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9122 * process.c (wait_reading_process_output): 'waitchannels' was unset
9123 when read_kbd || !NILP (wait_for_cell); fix this.
9125 Add GCC-style 'const' attribute to functions that can use it.
9126 * character.h (char_resolve_modifier_mask):
9127 * keyboard.h (make_ctrl_char):
9128 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9137 Add decls with ATTRIBUTE_CONST.
9139 Minor improvements to make_formatted_string.
9140 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9141 where int is good enough, as vsprintf returns an int.
9142 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9144 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9146 Use make_formatted_string to avoid double length calculation.
9147 * lisp.h (make_formatted_string): New prototype.

9171 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9173 Move marker debugging code under MARKER_DEBUG.
9174 * marker.c (MARKER_DEBUG): Move marker debugging code under
9175 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9176 for bootstrap with --enable-checking (~3x slowdown reported
9177 by Juanma Barranquero <lekktu@gmail.com>).
9178 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9180 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9182 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9183 See <http://bugs.gnu.org/11825#29>.
9185 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9187 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9188 has no font, use the frame's font. (Bug#11813)
9189 (display_line): Add commentary about displaying truncation glyphs
9191 (produce_special_glyphs): Move here from term.c.
9193 * term.c (produce_special_glyphs): Move to xdisp.c.
9195 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9198 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9200 * xdisp.c (display_line): Avoid warning about implicit declaration
9203 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9205 * lisp.h: Remove empty conditional.
9207 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9209 * lread.c (load_path_check): Now static.
9211 Fix some minor --with-ns problems found by static checking.
9212 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9213 (x_set_font) [!HAVE_X_WINDOWS]:
9214 * image.c (xpm_load_image) [HAVE_NS]:
9215 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9216 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9217 Remove unused local.
9218 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9219 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9220 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9221 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9222 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9223 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9224 Fix pointer signedness problem.

9226 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9228 2012-07-07 Glenn Morris <rgm@gnu.org>
9230 * lread.c (load_path_check): New function, split from init_lread.
9231 (init_lread): Reorganize. Motivation:
9232 If EMACSLOADPATH is set, check/warn about that rather than the
9233 defaults, which we are not going to use. Hence we can remove
9234 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9235 Don't warn if site-lisp directories are missing.
9236 If not installed, start from a blank load-path, since
9237 PATH_LOADSEARCH refers to the eventual installation directories.
9239 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9241 Support truncation and continuation glyphs on GUI frames, when
9242 fringes are disabled. (Bug#11832)
9243 * xdisp.c (init_iterator): Get dimensions of truncation and
9244 continuation glyphs even if on GUI frames.
9245 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9246 or both, are absent.
9247 (start_display, move_it_in_display_line_to): Handle the case of a
9248 GUI frame without a fringe to display continuation or truncation
9250 (insert_left_trunc_glyphs): Support GUI frames: make sure
9251 truncation glyphs overwrite enough glyphs from the current line to
9252 have sufficient space in pixels.
9253 (display_line): Support truncation and continuation glyphs on GUI
9254 frames. If some spare pixels are left on the line after inserting
9255 the truncation glyphs, fill that space with a stretch glyph of a
9256 suitably computed width.
9258 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9259 produce_glyphs, to support GUI sessions.
9261 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9263 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9265 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9267 Do not require float-time's arg to fit in time_t (Bug#11825).
9268 This works better on hosts where time_t is unsigned, and where
9269 float-time is applied to the (negative) difference between two times.
9270 * editfns.c (decode_time_components): Last arg is now double *,
9271 not int *, and means to store all the result as a double, without
9272 worrying about whether the seconds part fits in time_t.
9273 All callers changed.
9274 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9275 All callers changed.
9276 (Ffloat_time): Do not fail merely because the specified time falls
9277 outside of time_t range.
9279 2012-07-07 Glenn Morris <rgm@gnu.org>
9281 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9296 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9297 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9298 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

9301 * xfont.c (compare_font_names): Redo to omit the need for casts.
9303 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9305 * xfns.c (Fx_change_window_property): Doc fix.
9306 * w32fns.c (Fx_change_window_property): Doc fix.
9308 * w32fns.c (Fx_window_property): Accept the same arguments as the
9309 X Windows version. Doc fix.
9310 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9312 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9313 Eli Zaretskii <eliz@gnu.org>
9315 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9316 Windows-specific code from nt/config.nt moved here.
9317 Obsolete settings removed.
9319 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9321 * process.c: Avoid unnecessary calls to gettime.
9322 (wait_reading_process_output): Don't get the time of day
9323 when gobbling data immediately and not waiting, as there's no need
9324 for it in that case. This removes a FIXME.
9326 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9328 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9329 is defined (Bug#11768).
9331 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9333 Fix marker debugging code.
9334 * marker.c (byte_char_debug_check): Do not perform the check
9335 if buffer is not multibyte.
9336 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9337 Call byte_char_debug_check with correct arguments.
9339 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9341 Compile marker debugging code only if ENABLE_CHECKING is defined.
9342 * marker.c (byte_char_debug_check, count_markers):
9343 Use only if ENABLE_CHECKING is defined.
9344 (byte_debug_flag): Remove.
9345 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9346 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9348 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9350 Avoid code repetition in marker-related functions.
9351 * marker.c (attach_marker): New function.
9352 (Fset_marker, set_marker_restricted, set_marker_both)
9353 (set_marker_restricted_both): Use it.
9354 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9355 Consistently rename charno to charpos.
9356 (marker_position): Add eassert.
9357 (marker_byte_position): Convert to eassert.

9376 * window.c (save_window_save): Likewise.
9378 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9380 Do not use Fdelete_overlay in delete_all_overlays
9381 to avoid redundant calls to unchain_overlay.
9382 * buffer.c (drop_overlay): New function.
9383 (delete_all_overlays, Fdelete_overlay): Use it.
9384 * minibuf.c (get_minibuffer): Fix comment.

9388 Port to OpenBSD 5.1 amd64.
9389 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9390 This is needed for OpenBSD, and should be harmless on all BSD systems.
9391 Also, include <sys/sysctl.h>, as it should be available on all
9392 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9393 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9394 use p_pid member, not kp_proc.pid.
9396 2012-07-06 Glenn Morris <rgm@gnu.org>
9398 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9400 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9402 More xmalloc and related cleanup.

9411 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9413 Omit needless casts involving void * pointers and allocation.
9414 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9415 as the former is more robust if P's type is changed.
9416 Prefer xzalloc to xmalloc + memset 0.
9417 Simplify malloc-or-realloc to realloc.
9418 Don't worry about xmalloc returning a null pointer.
9419 Prefer xstrdup to xmalloc + strcpy.
9420 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9422 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9423 alloca of a constant.
9425 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9427 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9428 hscroll is larger than the line width. Fixes long and futile
9429 looping inside extend_face_to_end_of_line (on a TTY) producing
9430 glyphs that are not needed and thrown away.
9432 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9434 * marker.c (set_marker_restricted_both): Simplify by using

9460 * xdisp.c (window_hscroll_limited): New function.
9461 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9462 coordinates when window's hscroll is set to insanely large
9465 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9467 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9468 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

9528 * fileio.c (time_error_value): Check the right error number.
9529 Problem reported by Troels Nielsen in
9530 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9532 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9534 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9535 This should be fixed in a better way; see Eli Zaretskii in
9536 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9537 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9539 * fileio.c (time_error_value): Rename from special_mtime.
9540 The old name's problems were noted by Eli Zaretskii in
9541 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9543 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9544 This variable's comment says Emacs needs at least one GDB-visible
9545 symbol of type enum pvec_type, to work around GDB problems.
9546 The symbol's value doesn't matter.
9548 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9549 that causes compilation to fail on pre-C99 compilers.
9551 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9553 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9556 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9558 * buffer.c (init_buffer_once): Fix initialization of
9559 headers for buffer_defaults and buffer_local_symbols.
9560 Reported by Juanma Barranquero <lekktu@gmail.com>.
9562 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9564 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9565 * lisp.h (enum pvec_type): Use fewer bits.
9566 (PSEUDOVECTOR_SIZE_BITS): New constant.
9567 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9568 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9569 change in pvec_type.
9570 (PSEUDOVECTOR_TYPEP): New macro.
9571 (TYPED_PSEUDOVECTORP): Use it.
9572 * fns.c (internal_equal): Adapt code to extract pvectype.

9574 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9575 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9576 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9577 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9578 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9579 abusing vector->header.next.nbytes.
9580 (live_vector_p): Use PVEC_TYPE.
9581 (mark_object): Adapt code to extract pvectype. Use switch.
9583 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9585 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9586 Tighten new eassert a bit.
9588 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9590 Fix compilation with --enable-gcc-warnings and -O1
9592 * doprnt.c (doprnt): Change type of tem to int, initialize
9593 to avoid compiler warning. Add eassert.
9594 * search.c (simple_search): Initialize match_byte to avoid
9595 compiler warning. Add eassert.
9597 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9599 Avoid weird behavior with large horizontal scrolls.
9600 Without this change, for example, large hscroll values would
9601 mess up Emacs's display on Fedora 15 x86, presumably due to
9602 overflows in int calculations in the display code.
9603 Also, if buffers had long lines, Emacs would freeze.
9604 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9605 (set_window_hscroll): New function, containing the old guts of
9606 Fset_window_hscroll. Return the clipped value.
9607 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9608 This avoids the need to check against PTRDIFF_MAX.
9610 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9612 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9614 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9616 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9618 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9619 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9620 since GCC 4.4.6 issues a bogus warning for them.
9622 Fix bugs in file timestamp newness comparisons.
9623 * fileio.c (Ffile_newer_than_file_p):
9624 * lread.c (Fload): Use full timestamp resolution of files,
9625 not just the 1-second resolution, so that files that are only
9626 slightly newer still count as newer.
9627 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9628 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9630 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9632 * fileio.c: Improve handling of file time marker. (Bug#11852)
9633 (special_mtime): New function.
9634 (Finsert_file_contents, Fverify_visited_file_modtime):
9635 Use it to set special mtime values consistently.
9637 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9639 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9640 marker for non-existing file. (Bug#11852)
9642 2012-07-03 Glenn Morris <rgm@gnu.org>
9644 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9645 and did not make it into globals.h).
9647 2012-07-03 Tom Tromey <tromey@redhat.com>
9649 * window.c (Fset_window_margins, Fset_window_fringes)

9685 2012-07-03 Glenn Morris <rgm@gnu.org>
9687 * lisp.h (Frandom): Make it visible to C.
9688 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9689 buffer for invisible buffers. (Bug#1229)

9693 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9694 values which aren't power of 2.
9695 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9696 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9699 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9701 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9703 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9705 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9707 * alloc.c (allocate_vector_block): Remove redundant
9708 calls to mallopt if DOUG_LEA_MALLOC is defined.
9709 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9710 avoid calls to mallopt if zero_vector is returned.
9712 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9714 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9715 is enabled, avoid dereferencing NULL current_sblock if
9718 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9720 Cleanup basic buffer management.
9721 * buffer.h (struct buffer): Change layout to use generic vector
9722 marking code. Fix some comments. Change type of 'clip_changed'
9723 to bitfield. Remove unused #ifndef old.
9724 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9725 (GET_OVERLAYS_AT): Fix indentation.
9726 (for_each_per_buffer_object_at): New macro.

9730 * alloc.c (allocate_buffer): Adjust to match new layout of
9731 struct buffer. Fix comment.
9732 (mark_overlay): New function.

9735 (mark_object): Use it. Adjust marking of misc objects
9736 and related comments.
9738 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9740 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9741 wrapper that is not needed because the wrapped code is a no-op (zero
9742 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9743 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9745 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9747 * alloc.c (mark_buffer): Simplify. Remove prototype.
9748 (mark_object): Add comment. Reorganize marking of vector-like
9749 objects. Use CHECK_LIVE for all vector-like objects except buffers
9750 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9751 Avoid redundant calls to mark_vectorlike for bool vectors.
9753 2012-06-30 Glenn Morris <rgm@gnu.org>
9755 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9757 * epaths.in (PATH_SITELOADSEARCH): New.
9758 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9759 This is rather than relying on --enable-locallisppath elements
9760 having "site-lisp" in their names. (Bug#10208#25, 11658)
9762 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9764 * w32proc.c (sys_select): Accept and ignore one more argument.
9766 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9768 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9769 (pselect) [!MS_DOS]: Redirect to sys_select.
9771 * sysdep.c: Don't include dos.h and dosfns.h.
9773 * process.c (sys_select):
9774 * msdos.c (sys_select): Accept one more argument and ignore it.
9776 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9777 adapt data types and code to that.
9780 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9781 which clashes with the gnulib function of the same name.
9783 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9785 * font.c (font_style_to_value, font_style_symbolic)
9786 (font_prop_validate_style): Add type checks for values in
9789 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9791 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9794 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9796 * xdisp.c (try_window_id): Undo last change.
9798 * w32.c (getwd): Adjust commentary about startup_dir.
9799 (init_environment): Always call sys_access, even in non-MSVC
9800 builds. Don't chdir to the directory of the Emacs executable.
9801 This undoes code from 1997 which was justified by the need to
9802 "avoid conflicts when removing and renaming directories". But its
9803 downside was that every relative file name was being interpreted
9804 relative to the directory of the Emacs executable, which can never
9805 be TRT. In particular, it broke sys_access when called with
9806 relative file names.
9807 (sys_access): Map GetLastError to errno.
9809 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9811 * window.h (struct window): Change type of 'fringes_outside_margins'

9815 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9818 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9820 * gnutls.c (emacs_gnutls_handshake):
9821 Add QUIT to make the loop interruptible.
9823 2012-06-29 Glenn Morris <rgm@gnu.org>
9825 * charset.c (init_charset): Make lack of etc/charsets fatal.
9827 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9829 * editfns.c (region_limit): Fix type mismatch.
9831 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9833 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9834 undefined. Convert from xassert to eassert.
9835 * nsmenu.m: Convert from xassert to eassert.
9836 * nsterm.m: Likewise.
9838 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9840 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9842 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9844 Avoid integer overflow on scroll-left and scroll-right.
9845 * window.c (HSCROLL_MAX): New macro.
9846 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9847 overflow when requested scroll falls outside ptrdiff_t range.
9849 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9851 * window.h (struct window): Change type of 'hscroll',
9852 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9853 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9854 Adjust users accordingly.
9855 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9856 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9857 from EMACS_INT to ptrdiff_t.
9858 (make_window): Omit redundant initialization.
9860 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9864 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9866 * window.h (struct window): Change type of 'use_time' and
9867 'sequence_number' from Lisp_Object to int.

9877 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9878 adjust comments accordingly.

9929 avoid GCC warning about unused macro.
9931 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9933 * alloc.c (allocate_string): Omit intervals initialization.
9934 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9935 as in make_pure_string and make_pure_c_string.
9937 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9991 * alloc.c: Remove build_string.
9992 * lisp.h: Define build_string as static inline. This provides
9993 a better opportunity to optimize away calls to strlen when the
9994 function is called with compile-time constant argument.
9995 * image.c (imagemagick_error): Convert to build_string.
9996 * w32proc.c (sys_spawnve): Likewise.

9999 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10001 Use sprintf return value instead of invoking strlen on result.
10002 In the old days this wasn't portable, since some sprintf
10003 implementations returned char *. But they died out years ago and
10004 Emacs already assumes sprintf returns int.
10005 Similarly for float_to_string.
10006 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10007 * ccl.c (ccl_driver):
10008 * character.c (string_escape_byte8):
10009 * data.c (Fnumber_to_string):

10011 * print.c (print_object):
10012 * xdisp.c (message_dolog):
10013 * xfns.c (syms_of_xfns):
10014 Use sprintf or float_to_string result to avoid need to call strlen.
10015 * data.c (Fnumber_to_string):
10016 Use make_unibyte_string, since the string must be ASCII.
10017 * lisp.h, print.c (float_to_string): Now returns int length.
10018 * term.c (produce_glyphless_glyph):
10019 Use sprintf result rather than recomputing it.
10021 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10022 * Makefile.in (ALL_CFLAGS):
10023 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10024 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10026 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10028 * dispextern.h (xstrcasecmp): Define to library function
10029 strcasecmp if available.
10030 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10032 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10034 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10036 * menu.c (push_submenu_start, push_submenu_end)
10037 (push_left_right_boundary, push_menu_pane): Likewise.
10038 * msdos.c (dos_rawgetc): Likewise.

10045 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10047 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10048 sprintf already null-terminates its output.
10050 * xfns.c (x_window): Remove redundant cast.
10052 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10054 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10055 `const char *' to `char *' to avoid compiler warning.
10057 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10059 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10060 instead of truncating it to 63 (admittedly a generous limit).
10062 * process.c: Fix spelling and caps in comments.
10064 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10066 * emacs.c (setpgrp): Remove definition, unused.

10076 (SYSTIME_H): Add nt/inc/sys/time.h.
10078 * systime.h [WINDOWSNT]: Include sys/time.h.
10080 * s/ms-w32.h (struct timespec): Definition moved from
10081 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10083 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10113 Remove unnecessary forward decls.
10115 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10117 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10118 * lisp.h (WAIT_READING_MAX): New macro.
10119 * dispnew.c (Fsleep_for, sit_for):
10120 * keyboard.c (kbd_buffer_get_event):
10121 * process.c (Faccept_process_output):
10122 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10123 This improves on the previous patch, which introduced a bug
10124 when time_t is unsigned and as wide as intmax_t.
10125 See <http://bugs.gnu.org/9000#51>.
10127 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10129 * dispnew.c (sit_for, Fsleep_for):
10130 * keyboard.c (kbd_buffer_get_event):

10143 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10144 Privately reported by Herbert J. Skuhra.
10145 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10147 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10148 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10150 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10153 last argument of make_unibyte_string.
10155 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10156 language ID in the event parameters.
10158 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10159 event.code, not the obscure "character set ID".
10161 2012-06-23 Chong Yidong <cyd@gnu.org>
10163 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10186 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10187 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10188 Don't assume EMACS_TIME and struct timeval are the same type.
10190 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10192 Support higher-resolution time stamps (Bug#9000).
10193 The time stamps are only nanosecond-resolution at the C level,
10194 since that's the best that any real-world system supports now.
10195 But they are picosecond-resolution at the Lisp level, as that's
10196 easy, and leaves room for future OS improvements.
10198 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10201 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10202 Don't get current time unless it's needed.
10204 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10205 now provides it if it's absent.
10206 (start_atimer): Port to higher-res time stamps.
10207 Check for time stamp overflow. Don't get current time more
10208 often than is needed.
10210 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10211 Include systime.h, not time.h.
10212 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10214 * dired.c: Include stat-time.h.
10215 (Ffile-attributes): File times now have higher resolution.
10217 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10218 (struct image): Timestamp now has higher resolution.
10220 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10221 has at least microseconds now. All uses removed.
10222 (update_frame, update_single_window, update_window, update_frame_1)
10223 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10224 (duration_to_sec_usec): Remove; no longer needed.
10226 * editfns.c (time_overflow): Now extern.
10227 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10228 (float-time, Fformat_time_string, Fcurrent_time_string)
10229 (Fcurrent_time_zone): Accept and generate higher-resolution
10231 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10232 (decode_time_components, lisp_seconds_argument): New functions.
10233 (make_time): Now static.
10234 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10235 Report an error if the time is invalid, rather than having the caller
10238 * fileio.c: Include <stat-time.h>
10239 (Fcopy_file): Copy higher-resolution time stamps.
10240 Prefer to set the time stamp via a file descriptor if that works.
10241 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10242 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10243 (Fvisited_file_modtime, Fset_visited_file_modtime):
10244 Support higher-resolution time stamps.
10246 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10248 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10250 * image.c (prepare_image_for_display, clear_image_cache)
10251 (lookup_image): Port to higer-resolution time stamps.
10253 * keyboard.c (start_polling, bind_polling_period):
10254 Check for time stamp overflow.
10255 (read_char, kbd_buffer_get_event, timer_start_idle)
10256 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10257 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10258 Port to higher-resolution time stamps. Do not assume time_t is signed.
10259 (decode_timer): New function. Timers are now vectors of length 9,
10260 not 8, to accommodate the picosecond component.
10261 (timer_check_2): Use it.
10263 * nsterm.m (select_timeout, timeval_subtract): Remove.
10264 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10265 as they're a bit more accurate and handle overflow better.
10266 (ns_select): Change prototype to be compatible with pselect.
10267 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10268 * nsterm.h (ns_select): Adjust prototype.
10270 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10271 us-resolution time stamps.
10272 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10274 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10276 * lisp.h (time_overflow): New decl.
10277 (wait_reading_process_output): First arg is now intmax_t, not int,
10278 to accommodate larger waits.
10280 * process.h (struct Lisp_Process.read_output_delay):
10281 Now counts nanoseconds, not microseconds.
10282 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10284 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10285 (wait_reading_process_output):
10286 Port to ns-resolution time stamps.
10287 (Faccept_process_output, wait_reading_process_output):
10288 Check for time stamp overflow. Do not assume time_t is signed.
10289 (select_wrapper): Remove; we now use pselect.
10290 (Fprocess_attributes): Now generates ns-resolution time stamps.
10292 * sysdep.c: Include utimens.h. Don't include utime.h
10293 or worry about struct utimbuf; gnulib does that for us now.
10294 (gettimeofday): Remove; gnulib provides a substitute.
10295 (make_timeval): New function.
10296 (set_file_times): Now sets ns-resolution time stamps.
10297 New arg FD; all uses changed.
10298 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10299 (system_process_attributes):
10300 Now returns ns-resolution time stamp. All uses changed.
10301 Check for time stamp overflow.
10303 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10304 provides a substitute now.
10306 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10307 since it guarantees struct timespec.
10308 (EMACS_TIME): Now struct timespec, so that we can support
10309 ns-resolution time stamps.
10310 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10311 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10312 (EMACS_USECS): Remove.
10313 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10314 so multiply the arg by 1000 before storing it.
10315 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10317 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10318 Port to ns-resolution time stamps.
10319 (EMACS_TIME_NEG_P): Remove; replaced by....
10320 (EMACS_TIME_SIGN): New macro.
10321 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10322 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10323 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10324 (make_timeval, make_lisp_time, decode_time_components): New decls.
10325 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10326 that it mishandled time_t overflow. You can't compare by subtracting!
10327 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10328 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10330 * term.c: Include <sys/time.h>.
10331 (timeval_to_Time): New function, for proper overflow wraparound.
10332 (term_mouse_position, term_mouse_click): Use it.
10334 * undo.c (record_first_change): Support higher-resolution time stamps
10335 in the undo buffer.
10336 (Fprimitive_undo): Use them when restoring time stamps.
10338 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10339 (w32_get_internal_run_time):
10340 Port to higher-resolution Emacs time stamps.
10341 (ltime): Now accepts single 64-bit integer, as that's more convenient
10344 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10346 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10347 for compatibility with pselect. Support ns-resolution time stamps.
10349 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10351 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10352 Check for time stamp overflow, and support ns-resolution time stamps.
10354 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10355 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10356 (timeval_subtract): Remove; no longer needed.
10357 (XTflash, XTring_bell, x_wait_for_event):
10358 Port to ns-resolution time stamps. Don't assume time_t is signed.
10360 2012-06-22 Chong Yidong <cyd@gnu.org>
10362 * xdisp.c (x_consider_frame_title): Revert last change.
10364 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10366 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10367 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10368 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10369 staticidx goes up to 1597 out of 1600 = 0x640.)
10371 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10373 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10374 Otherwise, the umask might be mistakenly 0 while handling input signals.
10376 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10378 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10384 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10385 access to `contents' member of Lisp_Vector objects with AREF and ASET
10388 2012-06-19 Chong Yidong <cyd@gnu.org>
10390 * frame.c (delete_frame): When selecting a frame on a different
10391 text terminal, do not alter the terminal's top-frame.
10393 * xdisp.c (format_mode_line_unwind_data): Record the target
10394 frame's selected window and its terminal's top-frame.
10395 (unwind_format_mode_line): Restore them.
10396 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10398 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10399 since tty frames can be explicitly named.
10400 (prepare_menu_bars): Likewise.
10402 * term.c (Ftty_top_frame): New function.
10404 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10406 Port byte-code-meter to modern targets.
10407 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10408 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10409 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10410 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10411 (METER_1, METER_2): Simplify.
10413 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10415 * data.c (Fdefalias): Return `symbol' (bug#11686).
10417 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10419 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10420 gets killed during executing of this function (Bug#11665).
10421 Try to always return Qt when the buffer has been actually killed.
10422 (Vkill_buffer_query_functions): In doc-string say that functions
10423 run by this hook should not change the current buffer.

10644 Use an inline function on all platforms when using the union type,
10645 since this is simpler and 'static inline' can be used portably

10790 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10791 would mishandle a string argument "Xc" if X was a multibyte

10846 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10847 Convert pctcpu and pctmem to Lisp float properly.
10848 Let the compiler fold better, as 100.0/0x8000 is exact.

10852 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10875 Use 'float' consistently, rather than 'float' in most places
10876 and 'double' in a couple of places.
10878 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10880 * xdisp.c (handle_stop): Detect whether we have overlay strings
10881 loaded by testing it->current.overlay_string_index to be
10882 non-negative, instead of checking whether n_overlay_strings is
10883 positive. (Bug#11587)
10885 2012-05-31 Chong Yidong <cyd@gnu.org>
10887 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10889 * doc.c (Fsubstitute_command_keys): Doc fix.
10891 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10893 * search.c (search_buffer): Remove calls to
10894 r_alloc_inhibit_buffer_relocation, as it is now called by
10895 maybe_unify_char, which was the cause of relocation of buffer text
10898 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10900 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10901 for the duration of call to load_charset, to avoid problems with
10902 callers of maybe_unify_char that access buffer text through C
10905 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10906 decrement the inhibition flag, instead of just setting or
10909 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10911 Remove obsolete '#define static' cruft.
10912 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10913 This #undef was "temporary" in 2000; it is no longer needed
10914 now that '#define static' has gone away.
10915 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10916 (gray_bitmap_bits): Remove; no longer needed.
10917 All uses replaced with definiens.
10918 * xterm.c: Include "bitmaps/gray.xbm".
10920 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10922 Clean up __executable_start, monstartup when --enable-profiling.
10923 The following changes affect the code only when profiling.
10924 * dispnew.c (__executable_start): Rename from safe_bcopy.
10925 Define only on platforms that need it.
10926 * emacs.c: Include <sys/gmon.h> when profiling.
10927 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10928 (__executable_start): Remove decl, since lisp.h does it now.
10929 (safe_bcopy): Remove decl; no longer has that name.
10930 (main): Coalesce #if into single bit of code, for simplicity.
10931 Cast pointers to uintptr_t, since standard libraries want integers
10933 * lisp.h (__executable_start): New decl.
10935 2012-05-31 Glenn Morris <rgm@gnu.org>
10937 * image.c (Fimagemagick_types): Doc fix.
10939 2012-05-30 Jim Meyering <meyering@redhat.com>
10941 * callproc.c (Fcall_process_region): Include directory component
10942 in mkstemp error message (Bug#11586).
10944 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10946 * alloc.c, lisp.h (make_pure_vector): Now static.
10948 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10950 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10951 Move to byte-run.el.
10952 (Fautoload): Do the hash-doc more carefully.
10953 * data.c (Fdefalias): Purify definition, except for keymaps.
10954 (Qdefun): Move from eval.c.
10955 * lisp.h (Qdefun): Remove.
10956 * lread.c (read1): Tiny simplification.
10958 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10960 Do not create empty overlays with the evaporate property (Bug#9642).
10961 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10962 Bug#9642, but explicitly check that the buffer the overlay would
10963 be moved to is live and rearrange lines to make sure that errors
10964 will not put the overlay in an inconsistent state.
10965 (Fdelete_overlay): Cosmetics.
10967 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10969 * w32term.c (my_bring_window_to_top): New function.
10970 (x_raise_frame): Use handle returned by DeferWindowPos, which
10971 could be different from the original one.
10972 Call my_bring_window_to_top instead of my_set_foreground_window.
10975 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10976 by calling BringWindowToTop.
10978 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

10981 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10983 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10984 This avoids undefined behavior that might cause the eassert
10985 to not catch an out-of-range value.
10987 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10989 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10990 Update dependencies.
10992 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10994 * bidi.c (bidi_mirror_char): Fix last change.
10996 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10998 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10999 when referring to sectname field in printf format.
11001 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11003 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11004 Only r_alloc_inhibit_buffer_relocation needed to be added;
11005 the others were already declared.
11007 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11008 before checking whether it's out of range. Put the check inside
11010 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11012 2012-05-27 Ken Brown <kbrown@cornell.edu>
11014 * callproc.c (Fcall_process): Restore a line that was accidentally
11015 commented out in the 2011-02-13 change (bug#11547).
11017 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11019 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11020 defined on ralloc.c.
11022 * buffer.c [REL_ALLOC]: Remove prototypes of
11023 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11024 they are now on lisp.h.
11026 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11028 * search.c (search_buffer): Use it to inhibit relocation of buffer
11029 text while re_search_2 is doing its job, because re_search_2 is
11030 passed C pointers to buffer text. (Bug#11519)
11032 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11033 Update value to 24.
11035 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11036 state after an additional call to move_it_in_display_line_to, keep
11037 the values of it->max_ascent and it->max_descent found for the
11039 (pos_visible_p): Revert the comparison against bottom_y to what it
11040 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11043 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11045 Fix coding-related core dumps with gcc -ftrapv.
11046 The code was computing A - B, where A and B are pointers, and B is
11047 random garbage. This can lead to core dumps on platforms that
11048 have special pointer registers, and it also leads to core dumps on
11049 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11050 A - B only when B is initialized properly.
11051 * coding.c (coding_set_source, coding_set_destination): Return void.
11052 (coding_change_source, coding_change_destinations): New functions,
11053 with the old behaviors of coding_set_source and coding_set_destination.
11054 All callers that need an offset changed to use these new functions.
11056 2012-05-26 Glenn Morris <rgm@gnu.org>
11058 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11060 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11062 Extend mouse support on W32 text-mode console.
11063 * xdisp.c (draw_row_with_mouse_face):
11064 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11066 * w32console.c: Include window.h.
11067 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11069 (initialize_w32_display): Initialize mouse-highlight data.
11071 * w32inevt.c: Include termchar.h and window.h.
11072 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11073 moves, call note_mouse_highlight. If help_echo changed, call
11074 gen_help_event to produce help-echo message in the echo area.
11075 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11078 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11080 * lread.c (read1): Simplify slightly to avoid an overflow warning
11081 with GCC 4.7.0 on x86-64.
11083 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11085 * bidi.c (bidi_mirror_char): Revert last change: an int is
11086 definitely wide enough here.
11088 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11090 Fix integer width and related bugs (Bug#9874).
11091 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11092 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11093 (string_bytes, check_sblock, allocate_string_data):
11094 (compact_small_strings, Fmake_bool_vector, make_string)
11095 (make_unibyte_string, make_multibyte_string)
11096 (make_string_from_bytes, make_specified_string)
11097 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11098 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11100 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11101 (allocate_pseudovector):
11102 Use int, not EMACS_INT, where int is wide enough.
11103 (inhibit_garbage_collection, Fgarbage_collect):
11104 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11105 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11106 int might not be wide enough.
11107 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11108 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11109 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11110 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11111 (bidi_level_of_next_char, bidi_move_to_visually_next):
11112 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11113 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11114 (Fkill_buffer, Fset_buffer_major_mode)
11115 (advance_to_char_boundary, Fbuffer_swap_text)
11116 (Fset_buffer_multibyte, overlays_at, overlays_in)
11117 (overlay_touches_p, struct sortvec, record_overlay_string)
11118 (overlay_strings, recenter_overlay_lists)
11119 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11120 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11121 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11122 (Foverlay_recenter, last_overlay_modification_hooks_used)
11123 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11124 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11125 (validate_region): Omit unnecessary test for b <= e,
11126 since that's guaranteed by the previous test.
11127 (adjust_overlays_for_delete): Avoid pos + length overflow.
11128 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11129 (report_overlay_modification):
11130 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11131 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11132 Omit pointer cast, which isn't needed anyway, and doesn't work
11133 after the EMACS_INT -> ptrdiff_t change.
11134 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11135 * buffer.h: Adjust decls to match defn changes elsewhere.
11136 (struct buffer_text, struct buffer):
11137 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11138 Use EMACS_INT, not int, where int might not be wide enough.
11139 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11140 not int, to avoid needless 32-bit limit on 64-bit hosts.
11141 (exec_byte_code): Use tighter memory-full test, one that checks
11142 for alloca overflow. Don't compute the address of the object just
11143 before an array, as that's not portable. Use EMACS_INT, not
11144 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11145 * callint.c (Fcall_interactively):
11146 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11147 * callproc.c (call_process_kill, Fcall_process):
11148 Don't assume pid_t fits into an Emacs fixnum.
11149 (call_process_cleanup, Fcall_process, child_setup):
11150 Don't assume pid_t fits into int.
11151 (call_process_cleanup, Fcall_process, delete_temp_file)
11152 (Fcall_process_region):
11153 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11154 (Fcall_process): Simplify handling of volatile integers.
11155 Use int, not EMACS_INT, where int will do.
11156 * casefiddle.c (casify_object, casify_region, operate_on_word)
11157 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11158 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11159 (casify_object): Avoid integer overflow when overallocating buffer.
11160 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11161 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11162 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11163 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11164 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11165 integers are now checked earlier. All uses replaced with XINT.
11167 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11168 For CCL_MapSingle, check that content and value are in int range.
11169 (ccl_driver, Fregister_code_conversion_map):
11170 Check that Vcode_version_map_vector is a vector.
11171 (resolve_symbol_ccl_program): Check that vector header is in range.
11172 Always copy the vector, so that we can check its contents reliably
11173 now rather than having to recheck each instruction as it's being
11174 executed. Check that vector words fit in 'int'.
11175 (ccl_get_compiled_code, Fregister_ccl_program)
11176 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11177 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11178 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11179 contents are in range.
11180 (Fccl_execute_on_string): Check that status is in range.
11181 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11182 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11183 Accept and return EMACS_INT, not int, because callers can pass values
11184 out of 'int' range.
11185 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11186 (multibyte_chars_in_text, parse_str_as_multibyte)

11188 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11189 (string_escape_byte8, Fget_byte):
11190 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11191 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11192 avoid mishandling large integers.
11193 * character.h: Adjust decls to match defn changes elsewhere.
11194 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11195 (Ffind_charset_region):
11196 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11197 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11198 (load_charset_map_from_vector, Fdefine_charset_internal):
11199 Don't assume fixnum fits in int.
11200 (load_charset_map_from_vector, Fmap_charset_chars):
11201 Remove now-unnecessary CHECK_NATNUMs.
11202 (Fdefine_charset_internal): Check ranges here, more carefully.
11203 Don't rely on undefined behavior with signed left shift overflow.
11204 Don't assume unsigned int fits into fixnum, or that fixnum fits
11205 into unsigned int. Don't require max_code to be a valid fixnum;
11206 that's not true for gb10830 4-byte on a 32-bit host. Allow
11207 invalid_code to be a cons, for the same reason. Require code_offset
11208 to be a character. Avoid int overflow if max_char is close
11210 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11211 this is intended anyway and avoids some undefined behavior.
11212 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11213 INDEX_TO_CODE_POINT, as that's what it expects.
11214 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11215 * charset.h (DECODE_CHAR): Return int, not unsigned;
11216 this is what was intended anyway, and it avoids undefined behavior.
11217 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11218 integer-overflow issues.
11219 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11220 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11221 where the argument is EMACS_INT, and this behavior is not intended.
11222 * chartab.c (Fmake_char_table, Fset_char_table_range)
11223 (uniprop_get_decoder, uniprop_get_encoder):
11224 Don't assume fixnum fits in int.
11225 * cmds.c (move_point): New function, that does the gist of
11226 Fforward_char and Fbackward_char, but does so while checking
11227 for integer overflow more accurately.
11228 (Fforward_char, Fbackward_char): Use it.
11229 (Fforward_line, Fend_of_line, internal_self_insert)
11230 (internal_self_insert):
11231 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11232 Fix a FIXME, by checking for integer overflow when calculating
11233 target_clm and actual_clm.

11265 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11266 (consume_chars): Rewrite to not calculate an address outside buffer.
11267 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
11268 Don't access memory outside of the args array.
11269 (Fdefine_coding_system_internal): Check for charset-id overflow.
11270 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
11271 result of ENCODE_CHAR.

11953 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11954 * textprop.c, tparam.c (NULL): Remove.
11955 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11956 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11957 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11958 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11959 * xterm.c (input_signal_count): Assume volatile works.
11961 2012-05-21 Ken Brown <kbrown@cornell.edu>
11963 * xgselect.c (xg_select): Fix first argument in call to 'select'
11966 2012-05-20 Ken Brown <kbrown@cornell.edu>
11968 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11969 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11971 2012-05-19 Ken Brown <kbrown@cornell.edu>
11973 * xfns.c (x_in_use): Remove `static' qualifier.
11974 * xterm.h (x_in_use): Declare.
11975 * xgselect.c: Include xterm.h.
11976 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11977 and `display_arg' (bug#9754).
11979 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11981 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11983 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11984 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11986 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11988 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11990 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11991 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11993 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11994 reference to image_cache->refcount.
11995 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11997 2012-05-17 Juri Linkov <juri@jurta.org>
11999 * search.c (Fword_search_regexp, Fword_search_backward)
12000 (Fword_search_forward, Fword_search_backward_lax)
12001 (Fword_search_forward_lax): Move functions to isearch.el
12002 (bug#10145, bug#11381).
12004 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12006 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12008 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12010 * lread.c (init_obarray): Declare Qt and Qnil as special.
12012 2012-05-14 Glenn Morris <rgm@gnu.org>
12014 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12015 Put "libexec" before "bin", for the sake of init_callproc_1.
12017 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12019 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12021 * unexaix.c: Port to more-recent AIX compilers.
12022 (report_error, report_error_1, make_hdr, copy_sym)
12023 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12024 Make arguments const char *, not char *, to avoid violations of C
12025 standard and to fix some AIX warnings reported by Gilles Pion.
12027 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12029 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12030 already have overlays loaded.
12031 (handle_single_display_spec): Before returning without displaying
12032 fringe bitmap, synchronize the bidi iterator with the main display
12033 iterator, by calling iterate_out_of_display_property.
12034 (iterate_out_of_display_property): Detect buffer iteration by
12035 testing that it->string is a Lisp string.
12036 (get_next_display_element): When the current object is exhausted,
12037 and there's something on it->stack, call set_iterator_to_next to
12038 proceed with what's on the stack, instead of returning zero.
12039 (set_iterator_to_next): If called at the end of a Lisp string,
12040 proceed to consider_string_end without incrementing string
12041 position. Don't increment display vector index past the end of
12042 the display vector. (Bug#11417)
12043 (pos_visible_p): Don't report a position visible when move_it_to
12044 stopped at the last line of window, which happens to be scanned
12045 backwards by the bidi iteration. (Bug#11464)
12047 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12049 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12050 and right-margin display specs even if the spec is invalid or we
12051 are on a TTY, and thus unable to display on the fringes.
12052 That's because the text with the property will not be displayed anyway,
12053 so we need to signal to the caller that this is a "replacing"
12054 display spec. This fixes display when the spec is invalid or we
12057 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12059 * unexaix.c (make_hdr): Fix typo in prototype.
12060 This bug broke the build on AIX. Problem reported by Gilles Pion.
12062 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12064 * keyboard.c (kbd_buffer_get_event): Read special events also in
12065 batch mode. (Bug#11415)
12067 2012-05-12 Glenn Morris <rgm@gnu.org>
12069 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12071 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12073 * lisp.mk (lisp): Add newcomment.elc.
12075 2012-05-12 Glenn Morris <rgm@gnu.org>
12077 * Makefile.in (MKDIR_P): New, set by configure.
12078 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12080 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12082 Remove unused function hourglass_started.
12083 * dispextern.h (hourglass_started):
12084 * w32fns.c (hourglass_started):
12085 * xdisp.c (hourglass_started): Remove.
12087 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12089 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12090 Update dependencies.
12092 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12094 * xgselect.c (xg_select): Put maxfds+1 into a var.
12095 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12097 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12099 2012-05-10 Dave Abrahams <dave@boostpro.com>
12101 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12102 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12104 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12106 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12107 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12108 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12109 Initialize xd_registered_buses.
12111 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12113 Untag more efficiently if USE_LSB_TAG.
12114 This is based on a proposal by YAMAMOTO Mitsuharu in
12115 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12116 For an admittedly artificial (nth 8000 longlist) benchmark on
12117 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12118 Emacs's overall text size by 1%.
12119 * lisp.h (XUNTAG): New macro.
12120 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12121 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12122 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12123 * eval.c (Fautoload):
12124 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12125 * frame.h (XFRAME): Use XUNTAG.
12127 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12128 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12129 Remove unportable assumptions about print widths of types like
12131 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12132 intptr_t when converting between pointer and integer, to avoid GCC
12133 warnings about wrong width.
12135 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12137 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12138 stack for each reader_thread, instead of defaulting to 8MB
12139 determined by the linker. This avoids failures in creating
12140 subprocesses on Windows 7, see the discussion in this thread:
12141 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12143 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12145 Fix up display of the *Minibuf-0* buffer in the mini window.
12146 * keyboard.c (read_char): Don't clear the echo area if there's no
12148 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12149 contents of *Minibuf-0*) if there's no message displayed in its stead.
12151 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12153 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12156 2012-05-06 Chong Yidong <cyd@gnu.org>
12158 * lisp.mk (lisp): Update.
12160 2012-05-05 Jim Meyering <meyering@redhat.com>
12162 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12164 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12166 * data.c (PUT_ERROR): New macro.
12167 (syms_of_data): Use it. Add new error type `user-error'.
12168 * undo.c (user_error): New function.
12169 (Fprimitive_undo): Use it.
12170 * print.c (print_error_message): Adjust print style for `user-error'.
12171 * keyboard.c (user_error): New function.
12172 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12174 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12176 Do not limit current-time-string to years 1000..9999.
12177 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12178 (Fcurrent_time_string): Support any year that is supported by the
12179 underlying localtime representation. Don't use asctime, as it
12180 has undefined behavior for years outside the range -999..9999.
12182 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12184 Fix race conditions involving setenv, gmtime, localtime, asctime.
12185 Without this fix, interrupts could mess up code that uses these
12186 nonreentrant functions, since setting TZ invalidates existing
12187 tm_zone or tzname values, and since most of these functions return
12188 pointers to static storage.
12189 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12190 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12191 Grow the critical sections to include not just invoking
12192 localtime/gmtime, but also accessing these functions' results
12193 including their tm_zone values if any, and any related TZ setting.
12194 (format_time_string): Last arg is now struct tm *, not struct tm **,
12195 so that the struct tm is saved in the critical section.
12196 All callers changed. Simplify allocation of initial buffer, partly
12197 motivated by the fact that memory allocation needs to be outside
12198 the critical section.
12200 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12202 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12203 with RESET_INTERVAL.
12205 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12206 Remove duplicated buffer name initialization.
12208 2012-05-02 Jim Meyering <jim@meyering.net>
12210 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12212 * xfns.c (x_window): Use xstrdup (Bug#11375).
12214 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12216 * xdisp.c (pos_visible_p): If already at a newline from the
12217 display string before the 'while' loop, don't walk back the glyphs
12218 from it3.glyph_row. Solves assertion violation when the display
12219 string begins with a newline (egg.el). (Bug#11367)
12221 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12223 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12226 2012-05-01 Glenn Morris <rgm@gnu.org>
12228 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12229 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12230 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12231 All were removed before 23.1.
12233 * dispnew.c: Remove HAVE_LIBNCURSES test;
12234 it is always true on relevant platforms.
12236 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12237 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12239 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12241 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12243 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12244 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12247 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12249 Do not avoid creating empty evaporating overlays (Bug#9642).
12250 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12251 That is, do not delete an evaporating overlay if it becomes
12252 empty after its bounds are adjusted to fit within its buffer.
12253 This fix caused other problems, and I'm reverting it until we get
12254 to the bottom of them.
12256 2012-04-27 Chong Yidong <cyd@gnu.org>
12258 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12260 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12262 * xdisp.c (pos_visible_p): If the window start position is beyond
12263 ZV, start the display from buffer beginning. Prevents assertion
12264 violation in init_iterator when the minibuffer window is scrolled
12265 via the scroll bar.
12267 * window.c (window_scroll_pixel_based): Likewise.
12269 2012-04-27 Chong Yidong <cyd@gnu.org>
12271 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12273 2012-04-27 Glenn Morris <rgm@gnu.org>
12275 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12276 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12278 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12280 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12281 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12283 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12285 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12286 display element, check also the underlying string or buffer
12287 character. (Bug#11341)
12289 * w32menu.c: Include w32heap.h.
12290 (add_menu_item): If the call to AppendMenuW (via
12291 unicode_append_menu) fails, disable Unicode menus only if we are
12292 running on Windows 9X/Me.
12294 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12296 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12297 (xgetint): Add missing shift for LSB tags.
12299 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12301 * keyboard.c (read_char): Don't wipe echo area for select window
12302 events: These might get delayed via `mouse-autoselect-window'
12305 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12307 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12308 manipulation of :loaded-from data.
12310 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12312 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12313 now a cons (bug#11311).
12315 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12317 Do not create empty overlays with the evaporate property (Bug#9642).
12318 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12319 if it becomes empty after its bounds are adjusted to fit within
12320 its buffer. Without this fix, in a nonempty buffer (let ((o
12321 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12322 yields an empty overlay that has the evaporate property, which is
12323 not supposed to happen.
12325 Fix minor GTK3 problems found by static checking.
12326 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12327 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12328 (struct _EmacsFixedClass, emacs_fixed_get_type):
12329 Move decls here from emacsgtkfixed.h, since they needn't be public.
12330 (emacs_fixed_get_type): Now static.
12331 (emacs_fixed_class_init): Omit unused local.
12332 (emacs_fixed_child_type): Remove; unused.
12333 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12334 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12335 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12336 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12337 (EMACS_FIXED_GET_CLASS): Remove; unused.
12338 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12340 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12341 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12343 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12345 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12346 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12347 (__malloc_size_t, __malloc_ptrdiff_t):
12348 Remove. All uses removed, replaced by the definiens if needed,
12349 since we can assume C89 or better now.
12350 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12358 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12359 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12360 Define using prototypes, not old style.
12361 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
12362 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
12363 (align): Don't assume that signed integer overflow wraps around.
12364 Omit unused local var.
12365 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
12366 (_free_internal_nolock, memalign, mallochook, reallochook):
12367 Omit no-longer-needed casts.
12368 (valloc): Use getpagesize, not __getpagesize.
12369 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
12370 (struct hdr): The 'magic' member is now size_t, not unsigned long.
12372 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
12374 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
12376 Move functions from C to Lisp. Make non-blocking method calls
12377 the default. Implement further D-Bus standard interfaces.
12379 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

12388 (QCdbus_registered_signal): New Lisp objects.
12389 (XD_DEBUG_MESSAGE): Use sizeof.

12438 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12440 * sysdep.c [__FreeBSD__]: Minor cleanups.
12441 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12442 Use Emacs indenting style more consistently. Avoid some casts.

12527 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12528 (NEED_MEM_INSERT): New macro.
12529 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12530 Remove one incorrect comment and fix another.

12597 2012-04-11 Daniel Colascione <dancol@dancol.org>
12599 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12600 against is gone. It's better to use vfork now so that when Cygwin
12601 gains a new, working vfork, we use it automatically (bug#10398).
12603 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12656 * minibuf.c (Fread_variable): Callers changed.
12658 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12660 * xdisp.c (set_cursor_from_row): If the display string appears in
12661 the buffer at position that is closer to point than the position
12662 after the display string, display the cursor on the first glyph of
12663 the display string. Fixes cursor display when a 'display' text
12664 property immediately follows invisible text. (Bug#11094)
12666 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12668 composite.c: use 'double' consistently
12669 * composite.c (get_composition_id): Use 'double' consistently
12670 instead of converting 'float' to 'double' and vice versa; this is
12671 easier to understand and avoids a GCC warning.
12673 2012-04-09 Glenn Morris <rgm@gnu.org>

12720 [!WINDOWSNT]: New macros.
12721 (init_libxml2_functions, libxml2_loaded_p): New functions.

12725 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12727 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

12739 * indent.c (Fvertical_motion): If there is a display string at
12740 point, use it.vpos to compute how many lines to backtrack after
12741 move_it_to point. (Bug#11133)
12743 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12745 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12746 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12747 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12748 macros related to unification of CJK characters. For the details,
12749 see the discussion following the message here:
12750 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

12766 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12768 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12769 position we get to after a call to move_it_to fails the
12770 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12771 only if we wind up in a string from display property. (Bug#11063)
12773 * window.c (Fdelete_other_windows_internal): Invalidate the row
12774 and column information about mouse highlight, so that redisplay
12775 restores it after reallocating the glyph matrices. (Bug#7464)
12777 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12778 string comes from a `display' text property, use the buffer
12779 position of that property as if we actually saw that position in
12781 (move_it_by_lines): Remove the assertion that
12782 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12783 violated when there's a before-string at the beginning of a line.

12841 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12843 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12844 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12845 when fetching a multibyte character consumes more bytes than
12846 CHAR_BYTES returns, due to unification of CJK characters in
12847 string_char. (Bug#11073)
12849 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12851 * process.c (wait_reading_process_output): Handle pty disconnect
12852 by refraining from sending oneself a SIGCHLD (bug#10933).

12858 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12859 Mark string as coming from a prefix property.
12860 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12861 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12863 2012-03-21 Chong Yidong <cyd@gnu.org>
12865 * xfaces.c (Vface_remapping_alist): Doc fix.
12867 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12869 * w32proc.c (Fw32_set_console_codepage)
12870 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

12875 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12876 to reflect default non-nil value of redisplay-dont-pause.
12878 2012-03-19 Kenichi Handa <handa@m17n.org>
12880 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12881 it fit in a valid range (Bug#11003).
12883 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12885 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12886 that is not from display property, accept the row as a "cursor
12887 row" if one of the string's character has a non-nil `cursor'
12888 property. Fixes cursor positioning when there are newlines in
12889 overlay strings, e.g. in icomplete.el. (Bug#11035)
12891 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12893 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12895 2012-03-12 Chong Yidong <cyd@gnu.org>
12897 * eval.c (inhibit_lisp_code): Rename from
12898 inhibit_window_configuration_change_hook; move from window.c.
12900 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12901 * window.c (run_window_configuration_change_hook)
12902 (syms_of_window): Callers changed.

12908 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12910 2012-03-10 Chong Yidong <cyd@gnu.org>
12912 * frame.c (other_visible_frames): Don't assume the selected frame
12913 is visible (Bug#10955).
12915 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12917 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12921 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12922 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12925 2012-03-03 Glenn Morris <rgm@gnu.org>
12927 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12929 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12931 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12932 position past the first glyph_row that ends at ZV. (Bug#10902)
12933 (redisplay_window, next_element_from_string): Fix typos in
12935 (redisplay_window): Pass to move_it_vertically the margin in
12936 pixels, not in screen lines.
12938 2012-03-02 Glenn Morris <rgm@gnu.org>
12940 * buffer.c (buffer-list-update-hook): Doc fix.
12942 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12944 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12945 push_it before setting up the iterator for the first overlay
12946 string, even if we have an empty string loaded.
12947 (next_overlay_string): If there's an empty string on the iterator
12948 stack, pop the stack. (Bug#10903)
12950 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12952 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12953 Suggested by Stefan Monnier in
12954 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12955 * alloc.c (widen_to_Lisp_Object): New static function.
12956 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12957 and widening them to Lisp_Objects. This would work even if
12958 USE_LSB_TAG is defined and wide integers are used, which might
12959 happen in a future version of Emacs.
12961 2012-02-25 Chong Yidong <cyd@gnu.org>
12963 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12966 * xselect.c (Fx_selection_exists_p): Doc fix.
12967 (x_clipboard_manager_save_all): Print an informative message
12968 before saving to clipboard manager.
12970 2012-02-24 Chong Yidong <cyd@gnu.org>
12972 * keyboard.c (process_special_events): Handle all X selection
12973 requests in kbd_buffer, not just the next one (Bug#8869).
12975 2012-02-23 Chong Yidong <cyd@gnu.org>
12977 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12978 call when setting menu-bar-lines and tool-bar-lines parameters.
12979 (unwind_create_frame_1): New helper function.
12981 * window.c (inhibit_window_configuration_change_hook): New var.
12982 (run_window_configuration_change_hook): Obey it.
12983 (syms_of_window): Initialize it.
12985 2012-02-22 Chong Yidong <cyd@gnu.org>
12987 * xterm.c (x_draw_image_relief): Add missing type check for
12988 Vtool_bar_button_margin (Bug#10743).
12990 2012-02-21 Chong Yidong <cyd@gnu.org>
12992 * fileio.c (Vfile_name_handler_alist): Doc fix.
12994 * buffer.c (Fget_file_buffer): Protect against invalid file
12995 handler return value.
12997 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
12999 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13000 when computing $valmask.
13002 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13003 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13004 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13005 It's useless in that case, and it can cause problems on hosts
13006 that allocate halves of EMACS_INT values separately.
13007 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13008 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13009 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13010 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13011 it avoids undefined behavior on hosts where shifting right by more
13012 than the word width has undefined behavior.
13014 2012-02-19 Chong Yidong <cyd@gnu.org>
13016 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13017 (Funhandled_file_name_directory, Ffile_name_as_directory)
13018 (Fdirectory_file_name, Fexpand_file_name)
13019 (Fsubstitute_in_file_name): Protect against invalid file handler
13020 return values (Bug#10845).
13022 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13024 * .gdbinit (pitx): Fix incorrect references to fields of the

13034 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13036 2012-02-15 Chong Yidong <cyd@gnu.org>
13038 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13039 marked as special. Also, starting docstrings with * is obsolete.

13052 * keymap.c (Fsingle_key_description): Handle char ranges.
13054 2012-02-12 Chong Yidong <cyd@gnu.org>
13056 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13057 as that creates a dangerous corner case.
13059 * window.c (Fdelete_window_internal): Invalidate the mouse
13060 highlight (Bug#9904).
13062 2012-02-12 Glenn Morris <rgm@gnu.org>

13065 (Fx_get_selection_internal, Fx_disown_selection_internal)
13066 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13067 * nsselect.m (Fx_own_selection_internal)
13068 (Fx_disown_selection_internal, Fx_selection_exists_p)
13069 (Fx_selection_owner_p, Fx_get_selection_internal):
13070 Sync docs and argument specs with the xselect.c versions.
13072 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13074 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13076 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13078 * w32select.c (Fx_selection_exists_p): Sync doc string and
13079 argument list with xselect.c. (Bug#10783)

13092 2012-02-07 Chong Yidong <cyd@gnu.org>
13094 * buffer.c (Fbuffer_local_variables)
13095 (buffer_lisp_local_variables): Handle unbound vars correctly;
13096 don't let Qunbound leak into Lisp.
13098 2012-02-07 Glenn Morris <rgm@gnu.org>
13100 * image.c (Fimagemagick_types): Doc fix.
13102 * image.c (imagemagick-render-type): Change it from a lisp object
13103 to an integer. Move the doc here from the lisp manual.
13104 Treat all values not equal to 0 the same.

13116 2012-02-04 Chong Yidong <cyd@gnu.org>
13118 * nsterm.m: Declare a global (Bug#10694).
13120 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13122 * w32.c (get_emacs_configuration_options):
13123 Include --enable-checking, if specified, in the return value.
13125 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13127 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13128 after rounding frame sizes. (Bug#9723)

13132 * keyboard.c (adjust_point_for_property): Don't position point
13133 before BEGV. (Bug#10696)
13135 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13137 Handle overflow when computing char display width (Bug#9496).
13138 * character.c (char_width): Return EMACS_INT, not int.
13139 (char_width, c_string_width): Check for overflow when
13140 computing the width; this is possible now that individual
13141 characters can have unbounded width. Problem introduced
13142 by merge from Emacs 23 on 2012-01-19.
13144 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13159 2012-02-02 Kenichi Handa <handa@m17n.org>
13161 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13162 0, do not call append_composite_glyph.
13164 2012-02-02 Kenichi Handa <handa@m17n.org>
13166 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13168 (x_produce_glyphs): If the component of a composition is a null
13169 string, set it->pixel_width to 1 to avoid zero-width glyph.
13171 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13173 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13174 first 2 arguments are identical. This makes inserting large
13175 output from a subprocess an order of magnitude faster on
13176 MS-Windows, where all sbrk'ed memory is always contiguous.
13178 2012-01-31 Glenn Morris <rgm@gnu.org>
13180 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13216 2012-01-21 Chong Yidong <cyd@gnu.org>
13218 * floatfns.c (Fcopysign): Make the second argument non-optional,
13219 since nil is not allowed anyway.
13221 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>

13234 * character.c (char_width): New function.
13235 (Fchar_width, c_string_width, lisp_string_width):
13236 Use char_width (Bug#9496).

13258 he end column for display of highlight that ends on a newline
13261 2012-01-11 Glenn Morris <rgm@gnu.org>
13263 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
13264 from load-path also when installation-directory is nil. (Bug#10208)
13266 2012-01-10 Glenn Morris <rgm@gnu.org>
13268 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
13270 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
13271 Update template values to be closer to their typical values these days.
13273 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13275 * xdisp.c (rows_from_pos_range): Accept additional argument
13276 DISP_STRING, and accept any glyph in a row whose object is that
13277 string as eligible for mouse highlight. Fixes mouse highlight of
13278 display strings from overlays. (Bug#10464)
13280 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
13282 emacs: fix an auto-save permissions race condition (Bug#10400)
13283 * fileio.c (auto_saving_dir_umask): New static var.
13284 (Fmake_directory_internal): Use it.
13285 (do_auto_save_make_dir): Set it, instead of invoking chmod after
13286 creating the directory. The old code temporarily assigns
13287 too-generous permissions to the directory.
13288 (do_auto_save_eh): Clear it.
13289 (Fdo_auto_save): Catch all errors, not just file errors, so
13290 that the var is always cleared.
13292 2012-01-07 Eli Zaretskii <eliz@gnu.org>
13294 * search.c (scan_buffer): Pass character positions to
13295 know_region_cache, not byte positions. (Bug#6540)

13799 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13800 to 4 (xorl, subq, cmpq, setbe).
13801 * alloc.c (pure): Always extern now, since that's the
13802 VIRT_ADDR_VARIES behavior.
13803 (PURE_POINTER_P): Use a single comparison, not two, for
13804 consistency with the new puresize.h.
13805 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13806 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13814 behave as if the cursor position were at the window margin.
13816 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13817 and the cursor position is out of bounds, behave as if the cursor
13818 position were at the window margin. (Bug#10075)

13889 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13891 * xdisp.c (display_line): Move the call to
13892 highlight_trailing_whitespace before the call to
13893 compute_line_metrics, since the latter needs to see the final
13894 faces of all the glyphs to compute ROW's hash value.
13895 Fixes assertion violations in row_equal_p. (Bug#10035)
13897 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13899 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

13904 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13905 with user-defined heap size. Bump the default size of the temacs

13959 The trivial performance wins aren't worth the portability hassles; see
13960 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13962 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14036 (window_box_width, window_box_left, window_box_left_offset)
14037 (window_box_right, window_box_right_offset): Declare extern.
14038 Otherwise, these inline functions do not conform to C99 and
14039 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14040 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14041 * intervals.c (adjust_intervals_for_insertion)

14044 (static_offset_intervals): Remove.
14045 (offset_intervals): Rewrite using the old contents of
14046 static_offset_intervals. The old version didn't conform to C99
14047 because an extern inline function contained a reference to an
14048 identifier with static linkage.

14101 (unwind_create_frame): New function (Bug#9943).
14102 (Fx_create_frame): Restructure code to be more similar to the one in
14103 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

14251 possible random value that matches one of those tested as
14252 condition to clear the mouse face.
14254 2011-10-28 Chong Yidong <cyd@gnu.org>
14256 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14258 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14260 * window.c (make_window): Initialize phys_cursor_on_p.
14262 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14264 * lisp.h (struct Lisp_Symbol): Update comments.
14266 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14268 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14270 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14272 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14273 <oslsachem@gmail.com> for helping to debug this.
14275 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14276 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14277 (g_b_init_get_glyph_outline_w): New static variables.
14278 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14279 (GetGlyphOutlineW_Proc): New typedefs.
14280 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14281 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14283 (w32font_open_internal, compute_metrics):
14284 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14285 instead of calling the "wide" APIs directly.
14287 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14289 * w32.h (syms_of_w32font): Add prototype.
14291 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14293 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14294 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14295 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14296 (Fmove_to_window_line): Doc fix.
14298 2011-10-27 Chong Yidong <cyd@gnu.org>
14300 * process.c (make_process): Set gnutls_state to NULL.
14302 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14303 non-NULL, regardless of GNUTLS_INITSTAGE.
14304 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14305 an error. Set process slots as soon as we allocate them.
14307 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14309 2011-10-27 Chong Yidong <cyd@gnu.org>
14311 * gnutls.c (emacs_gnutls_deinit): New function.
14312 Deallocate credentials structures as well as calling gnutls_deinit.
14313 (Fgnutls_deinit, Fgnutls_boot): Use it.
14315 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14316 (deactivate_process): Call emacs_gnutls_deinit.
14318 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14320 * image.c (x_create_x_image_and_pixmap):
14321 * w32.c (sys_rename, w32_delayed_load):
14322 * w32font.c (fill_in_logfont):
14323 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14325 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14327 * w32fns.c (w32_default_color_map): New function,
14328 extracted from Fw32_default_color_map.
14329 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14331 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14333 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14335 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14337 * keyboard.c (test_undefined): New function (bug#9751).
14338 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14340 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14342 * sysdep.c (init_sys_modes): Fix the check for the controlling
14343 terminal (Bug#6649).
14345 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14347 * dispextern.h (struct bidi_it): New member next_en_type.
14349 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14350 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14351 current character, check also for next_en_type being WEAK_EN.
14352 (bidi_resolve_weak): Don't enter the expensive loop if the current
14353 position is before next_en_pos. Record the bidi type of the first
14354 non-ET, non-BN character we find, in addition to its position.
14355 (bidi_level_of_next_char): Invalidate next_en_type when
14356 next_en_pos is over-stepped.
14358 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14360 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14361 * editfns.c: Rewrite current-time-zone so that it invokes
14362 the equivalent of (format-time-string "%Z") to get the time zone name.
14363 This fixes a bug when the time zone name contains characters that
14364 need converting from the system time locale to Emacs internal format.
14365 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14366 that patch fixed format-time-string to do the conversion, but
14367 I forgot to fix current-time-zone.
14368 (format_time_string): New function, containing most of
14369 what Fformat_time_string used to contain.
14370 (Fformat_time_string): Rewrite in terms of format_time_string.
14371 This doesn't change this function's behavior.
14372 (current-time-zone): Rewrite to use format_time_string.
14373 This fixes the bug reported by Michael Schierl in
14374 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14375 Jason Rumney's 2007-06-07 change worked around this bug, but
14377 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14379 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14381 * xdisp.c (start_display): If the character at POS is displayed
14382 via a display vector, reset IT->current.dpvec_index to zero.
14383 (try_window_reusing_current_matrix): If a line ends in a display
14384 vector or the next line starts in a display vector, continue
14385 redrawing the window even though the character position of
14386 start_row was reached.
14389 2011-10-18 Chong Yidong <cyd@gnu.org>
14391 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14392 with nobreak-char-display too.
14394 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14396 Fix part 3 of bug#9771.
14397 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14398 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14399 non-neutral characters if the current character is a paragraph
14400 separator (a.k.a. Newline). This avoids running the same
14401 expensive loop twice, once when we consume the preceding newline
14402 and the other time when the line actually needs to be displayed.
14403 Avoid the loop when we see neutrals on the base embedding level
14404 following a character whose directionality is the same as the
14405 paragraph's. This avoids running the expensive loop when a line
14406 ends in a long sequence of neutrals, like control characters.
14407 Add assertion against STRONG_AL type. Slightly rearrange code
14408 that determines the type of a neutral given the first non-neutral
14410 (bidi_level_of_next_char): Set next_en_pos to zero when
14411 invalidating its info.
14413 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14415 * xdisp.c (push_display_prop): Determine whether to record string
14416 or buffer position by IT->string, not by IT->method. Allow
14417 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14418 (move_it_vertically_backward): Don't look for character position
14419 immediately after the newline when in a continuation line.
14422 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14424 * window.c (coordinates_in_window): Rewrite and delabelize
14425 vertical border check. (Bug#5357) (Bug#9618)
14427 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14429 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14430 errors in XSetWindowBorder (bug#9310).
14432 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14434 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14435 avoid crash when xmalloc overrun checking is enabled.
14437 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14439 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14440 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14441 cursor motion with <left> and <right> arrow keys.
14443 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14444 some callers set that themselves.
14446 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14448 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14449 display string and the previous row comes from the same string and
14450 is empty. (Bug#9739) (Bug#9738)
14452 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14454 * doc.c (get_doc_string): Encode file name (bug#9735).
14456 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14458 * bidi.c (bidi_level_of_next_char):
14459 * xdisp.c (get_visually_first_element): Remove old incorrect
14460 comments regarding the Unicode Line Separator character.
14462 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14464 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14466 * alloc.c (Fgc_status): Do not access beyond zombies array
14467 boundary if nzombies > MAX_ZOMBIES.
14468 * alloc.c (dump_zombies): Add missing format specifier.
14470 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14472 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14473 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14475 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14476 Some packages use them to denote characters with modifiers.
14478 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14480 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14481 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14482 matching a pp-number. Rename parameter var to var1.
14484 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14486 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14488 2011-10-08 Glenn Morris <rgm@gnu.org>
14490 * callint.c (Fcall_interactively): Give a more explicit error for the
14491 'c' case with a non-character input. (Bug#8479)
14493 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14495 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14497 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14498 lines that are hscrolled on the left.
14500 * dispnew.c (buffer_posn_from_coords): Account for a possible
14501 presence of header-line. (Bug#4426)
14503 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14505 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14506 Don't advertise functionality which we discourage or doesn't work.
14508 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14510 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14511 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14512 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14513 this makes Emacs dump core during garbage collection on rare
14514 occasions. sizeof is obviously inferior to offsetof here, so
14515 stick with offsetof.
14516 (GC_POINTER_ALIGNMENT): New macro.
14517 (mark_memory): Omit 3rd (offset) arg; caller changed.
14518 Don't assume EMACS_INT alignment is the same as pointer alignment.
14520 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14522 * keyboard.c (read_key_sequence_remapped): New var.
14523 (read_key_sequence): Compute remapping in the right buffer.
14524 (command_loop_1): Use read_key_sequence's remapping directly.
14526 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14528 * dired.c (file_name_completion): Don't expand file name.
14529 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14530 before checking file name handler.
14532 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14533 they've been requested explicitly (bug#9591).
14535 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14537 * keymap.c (Fsingle_key_description): Use make_specified_string
14538 instead of build_string to build string from push_key_description.
14541 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14543 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14544 This fixes a Y2038 bug on 64-bit hosts.
14545 * buffer.c (reset_buffer):
14546 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14547 (Fclear_buffer_auto_save_failure):
14548 Use 0, not -1, to represent an unset failure time, since time_t
14549 might not be signed.
14551 Remove dependency on glibc malloc internals.
14552 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14553 Move back here from lisp.h, but with their new implementations.
14554 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14555 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14556 * charset.c (charset_table_init): New static var.
14557 (syms_of_charset): Use it instead of xmalloc. This removes a
14558 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14559 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14560 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14561 Move back to alloc.c.
14562 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14563 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14565 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14567 * nsterm.m (windowDidResize): Call x_set_window_size only when
14568 ns_in_resize is true. Otherwise set pixelwidth/height and
14569 call change_frame_size (Bug#9628).
14571 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14573 Port --enable-checking=all to Fedora 14 x86-64.
14574 * charset.c (syms_of_charset): Also account for glibc malloc's
14575 internal overhead when calculating the initial malloc maximum.
14577 Port --enable-checking=all to Fedora 14 x86.
14578 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14580 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14581 (overrun_check_realloc, overrun_check_free):
14582 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14583 That way, xmalloc returns a properly-aligned pointer even if
14584 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14585 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14586 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14587 into account when calculating the initial malloc maximum.
14588 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14589 Move here from alloc.c, so that charset.c can use it too.
14590 Properly align; the old code wasn't right for common 32-bit hosts
14591 when configured with --enable-checking=all.
14592 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14593 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14595 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14597 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14600 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14602 * xdisp.c (compute_display_string_end): If there's no display
14603 string at CHARPOS, return -1.
14605 * bidi.c (bidi_fetch_char): When compute_display_string_end
14606 returns a negative value, treat the character as a normal
14607 character not covered by a display string. (Bug#9624)
14609 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14611 * lread.c (Fread_from_string): Fix typo in docstring.
14613 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14615 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14616 newline, reseat the iterator instead of bidi-iterating there one
14617 character at a time. (Bug#9610)
14618 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14619 TO_CHARPOS if the bidi iterator is at base embedding level.
14621 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14623 * lread.c (readevalloop): Use correct code for NBSP.
14624 (read1): Likewise. (Bug#9608)
14626 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14628 * dbusbind.c (Fdbus_register_signal): When service is not
14629 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14631 2011-09-25 Glenn Morris <rgm@gnu.org>
14633 * buffer.c (truncate-lines): Doc fix.
14635 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14637 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14638 (Fset_window_next_buffers): Doc fix.
14640 2011-09-24 Glenn Morris <rgm@gnu.org>
14642 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14644 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14646 Fix minor problems found by static checking.
14647 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14648 * indent.c (Fvertical_motion): Fix == vs = typo.
14650 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14652 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14653 Default value is now t. Doc fix.
14655 * indent.c (Fvertical_motion): Compute and apply the overshoot
14656 logic when moving up, not only when moving down. Fix the
14657 confusing name and values of the it_overshoot_expected variable;
14658 logic changes accordingly. (Bug#9254) (Bug#9549)
14660 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14661 CHARPOS is covered by a display string which includes newlines.
14662 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14663 is covered by a display string with embedded newlines.
14665 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14667 * dbusbind.c (Fdbus_register_signal): Add match rule to
14668 Vdbus_registered_objects_table. (Bug#9581)
14669 (Fdbus_register_method, Vdbus_registered_objects_table):
14672 2011-09-24 Jim Meyering <meyering@redhat.com>
14674 do not ignore write error for any output size
14675 The previous change was incomplete.
14676 While it makes emacs --batch detect the vast majority of stdout
14677 write failures, errors were still ignored whenever the output size is
14678 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14679 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14680 && echo FAIL: ignored write error
14681 FAIL: ignored write error
14682 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14683 && echo FAIL: ignored write error
14684 FAIL: ignored write error
14685 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14687 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14689 * emacs.c (Fkill_emacs): In noninteractive mode exit
14690 non-successfully if a write error occurred on stdout. (Bug#9574)
14692 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14694 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14697 * dispextern.h (struct it): Update the comment documenting what
14700 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14702 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14703 a display string, extend search for cursor position to end of row.
14704 (find_row_edges): If the row ends in a newline from a display
14705 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14706 Handle the case of a display string with multiple newlines.
14707 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14708 non-empty line. Fixes confusing cursor motion with arrow keys at
14709 the beginning of a line that starts with whitespace.
14711 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14713 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14716 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14718 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14719 boolean (Bug#9154).
14721 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14723 * xdisp.c (display_line): Record maximum and minimum buffer
14724 positions even if no glyphs were produced (e.g., by a zero-width
14725 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14726 buffer positions that will be removed from the glyph row because
14728 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14729 column is beyond frame width: don't subtract 1 "pixel" when
14730 computing width of the stretch.
14731 (reseat_at_next_visible_line_start): Undo the change made on
14732 2011-09-17 that saved paragraph information and restored it after
14733 the call to `reseat'. (Bug#9545)
14735 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14737 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14738 and turn window cursor on if cleared (Bug#9415).
14740 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14742 * search.c (boyer_moore): Take unibyte characters from pattern
14743 literally. (Bug#9458)
14745 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14747 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14749 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14751 Fix minor problem found by static checking.
14752 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14753 initialized, to pacify gcc -Wuninitialized.
14755 * fileio.c: Report proper errno when syscall falls.
14756 (Finsert_file_contents): Save and restore errno,
14757 so that report_file_error outputs the correct diagnostic.
14758 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14760 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14762 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14764 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14766 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14767 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14769 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14771 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14772 about the current paragraph and restore it after the call to reseat.
14774 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14775 (bidi_find_paragraph_start): Search back for paragraph beginning
14776 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14777 (bidi_move_to_visually_next): Only trigger paragraph-related
14778 computations when the last character is a newline or at EOB, not
14779 just any NEUTRAL_B. (Bug#9470)
14781 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14782 truncated lines if point is covered by a display string. (Bug#9524)
14784 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14786 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14787 (cons_to_x_long): New function.
14788 (lisp_data_to_selection_data): Use it. Correct the test for
14789 short-versus-long data; it was negated. Break out of vector
14790 loop, for efficiency, when a long datum is discovered.
14792 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14794 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14796 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14798 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14799 GCC PR/17406) by declaring this function with external scope.
14801 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14803 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14804 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14806 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14808 * editfns.c (Fformat): Correctly handle text properties on "%%".
14810 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14812 * xterm.c (x_draw_composite_glyph_string_foreground):
14813 * w32term.c (x_draw_composite_glyph_string_foreground):
14814 * term.c (encode_terminal_code):
14815 * composite.c (composition_update_it, get_composition_id):
14816 * xdisp.c (get_next_display_element)
14817 (fill_composite_glyph_string): Add comments about special meaning
14818 of TAB characters in a composition.
14820 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14822 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14823 This occurs when processing a multibyte format.
14824 Problem reported by Wolfgang Jenker.
14826 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14828 * xdisp.c (try_cursor_movement): Only check for exact match if
14829 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14831 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14833 Remove unused external symbols.
14834 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14835 * xdisp.c (calc_pixel_width_or_height): Now static.
14836 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14837 * indent.c (check_display_width):
14838 * w32term.c: Fix comment to match code.
14839 * xterm.c, xterm.h (x_catching_errors): Remove.
14841 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14843 * xselect.c: Use signed conversions more consistently (Bug#9498).
14844 (selection_data_to_lisp_data): Assume incoming selection data are
14845 signed integers, not unsigned. This is to be consistent with
14846 outgoing selection data, which was modified to use signed integers
14847 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14848 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14849 expects long, not unsigned long.
14851 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14853 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14854 computation of loop end. Reported by Johan Bockgård
14857 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14859 * frame.c (Fother_visible_frames_p): Function deleted.
14861 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14863 * indent.c (compute_motion): Process display vector front to back
14864 rather than the other way around. (Bug#2496)
14866 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14868 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14870 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14872 * minibuf.c (Fread_from_minibuffer): Doc fix.
14874 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14876 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14877 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14879 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14881 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14882 value for non-existent files.
14884 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14886 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14887 set its "size" to -1. This will set the modtime_size field of
14888 the corresponding buffer to -1, which is what
14889 verify-visited-file-modtime expects for files that do not exist.
14892 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14894 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14896 * lisp.h: ... from here. push_key_description is no longer
14897 defined in keyboard.c, so its declaration should not be in
14898 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14899 logically belongs with push_key_description.
14901 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14903 * buffer.h: Include <sys/types.h> instead of <time.h>.
14904 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14905 Problem reported by Herbert J. Skuhra.
14907 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14909 * xml.c (parse_region): Make the parsing work for
14910 non-comment-starting XML files again (bug#9144).
14912 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14914 * image.c (gif_load): Fix calculation of bottom and right corner.
14917 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14919 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14920 redisplay in small windows.
14922 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14924 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14926 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14928 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14929 Operate on live windows only.
14931 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14933 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14935 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14937 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14938 only under bidi iteration.
14940 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14942 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14944 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14946 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14947 Without this fix, the command to link temacs failed due to an
14948 undefined symbol __builtin_isnan. This is because
14949 /usr/include/iso/math_c99.h #defines isnan(x) to
14950 __builtin_isnan(x), but the bundled gcc, which identifies itself
14951 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14953 * floatfns.c (isnan): #undef, and then #define to a clone of
14955 (Fisnan): Always define, since it's always available now.
14956 (syms_of_floatfns): Always define isnan at the Lisp level.
14958 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14960 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14962 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14964 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14965 The previous code assumed that file offsets (off_t values) fit in
14966 EMACS_INT variables, which is not true on typical 32-bit hosts.
14967 The code messed up by falsely reporting buffer overflow in cases
14968 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14969 when "big" contains more than 2**29 bytes, even though this
14970 inserts just one byte and does not overflow the buffer.
14971 (Finsert_file_contents): Store file offsets as off_t
14972 values, not as EMACS_INT values. Check for overflow when
14973 converting between EMACS_INT and off_t. When checking for
14974 buffer overflow or for overlap, take the offsets into account.
14975 Don't use EMACS_INT for small values where int suffices.
14976 When checking for overlap, fix a typo: ZV was used where
14977 ZV_BYTE was intended.
14978 (Fwrite_region): Don't assume off_t fits into 'long'.
14979 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14981 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14983 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14985 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14987 sprintf-related integer and memory overflow issues (Bug#9412).
14989 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14990 (esprintf, exprintf, evxprintf): New functions.
14991 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14992 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14993 (modify_event_symbol): Do not assume that the length of
14994 name_alist_or_stem is safe to alloca and fits in int.
14995 (Fexecute_extended_command): Likewise for function name and binding.
14996 (Frecursion_depth): Wrap around reliably on integer overflow.
14997 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14998 since some callers pass EMACS_INT values.
14999 (Fsingle_key_description): Don't crash if symbol name contains more
15000 than MAX_ALLOCA bytes.
15001 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15002 (get_minibuffer): Arg is now EMACS_INT, not int.
15003 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15004 (esprintf, exprintf, evxprintf): New decls.
15005 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15007 * dbusbind.c (signature_cat): New function.
15008 (xd_signature, Fdbus_register_signal):
15009 Do not overrun buffer; instead, report string overflow.
15011 * dispnew.c (add_window_display_history): Don't overrun buffer.
15012 Truncate instead; this is OK since it's just a log.
15014 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15015 even if the time zone offset is outlandishly large.
15016 Don't mishandle offset == INT_MIN.
15018 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15019 when creating daemon; the previous buffer-overflow check was incorrect.
15021 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15022 which has the guts of the old verror function.
15024 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15025 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15027 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15028 (font_unparse_xlfd): Don't blindly alloca long strings.
15029 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15030 fits in int, when using sprintf. Use single snprintf to count
15031 length of string rather than counting it via multiple sprintfs;
15032 that's simpler and more reliable.
15033 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15034 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15035 sprintf, in case result does not fit in int.
15037 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15038 (fontset_from_font): Print it.
15040 * frame.c (tty_frame_count): Now printmax_t, not int.
15041 (make_terminal_frame, set_term_frame_name): Print it.
15042 (x_report_frame_params): In X, window IDs are unsigned long,
15043 not signed long, so print them as unsigned.
15044 (validate_x_resource_name): Check for implausibly long names,
15045 and don't assume name length fits in 'int'.
15046 (x_get_resource_string): Don't blindly alloca invocation name;
15047 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15050 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15051 (xg_check_special_colors, xg_set_geometry):
15052 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15054 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15055 Use esprintf, not sprintf, in case result does not fit in int.
15057 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15058 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15059 it as a large positive number.
15060 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15061 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15063 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15064 in case result does not fit in int.
15066 * print.c (float_to_string): Detect width overflow more reliably.
15067 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15068 buffer overrun. Don't assume list length fits in 'int'. Treat
15069 print length of 0 as 0, not as infinity; to be consistent with other
15070 uses of print length in this function. Don't overflow print length
15071 index. Don't assume hash table size fits in 'long', or that
15072 vectorlike size fits in 'unsigned long'.
15074 * process.c (make_process): Use printmax_t, not int, to format
15075 process-name gensyms.
15077 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15079 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15080 to avoid potential buffer overrun.
15082 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15083 if X resource line is longer than 512 bytes.
15085 * xfns.c (x_window): Make sprintf buffer a bit bigger
15086 to avoid potential buffer overrun.
15088 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15090 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15092 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15094 Integer overflow fixes for scrolling, etc.
15095 Without these, Emacs silently mishandles large integers sometimes.
15096 For example, "C-u 4294967297 M-x recenter" was treated as if
15097 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15099 * xdisp.c (try_window_id): Check Emacs fixnum range before
15100 converting to 'int'.
15102 * window.c (window_scroll_line_based, Frecenter):
15103 Check that an Emacs fixnum is in range before assigning it to 'int'.
15104 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15105 values converted from Emacs fixnums.
15106 (Frecenter): Don't wrap around a line count if it is out of 'int'
15107 range; instead, treat it as an extreme value.
15108 (Fset_window_configuration, compare_window_configurations):
15109 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15111 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15112 that can exceed INT_MAX. Check that EMACS_INT value is in range
15113 before assigning it to the (possibly-narrower) index.
15114 (match_limit): Don't assume that a fixnum can fit in 'int'.
15116 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15119 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15120 (Fvertical_motion): Don't wrap around LINES values that don't fit
15121 in 'int'. Instead, treat them as extreme values. This is good
15122 enough for windows, which can't have more than INT_MAX lines anyway.
15124 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15126 * Require libxml/parser.h to avoid compilation warning.
15128 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15130 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15131 since this reportedly can destroy thread storage.
15133 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15135 * syntax.c (find_defun_start): Update all cache variables if
15136 exiting early (Bug#9401).
15138 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15140 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15142 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15143 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15144 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15146 * term.c (tty_append_glyph): New function.
15147 (produce_stretch_glyph): Static function and its prototype deleted.
15149 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15152 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15154 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15155 when checking :margin (Bug#9390).
15156 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15157 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15158 so that the name doesn't mislead. All uses changed.

15170 the first character in the line after the newline.
15172 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15174 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15175 (ccl_driver): Do not generate an out-of-range pointer.
15176 (Fccl_execute_on_string): Remove unnecessary check for
15177 integer overflow, noted by Stefan Monnier in
15178 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15179 Remove a FIXME that didn't need fixing.
15180 Simplify the newly-introduced buffer reallocation code.
15182 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15184 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15186 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15188 Integer and memory overflow issues (Bug#9196).
15190 * doc.c (get_doc_string): Rework so that
15191 get_doc_string_buffer_size is the actual buffer size, rather than
15192 being 1 less than the actual buffer size; this makes xpalloc more
15195 * image.c (x_allocate_bitmap_record, cache_image):
15196 * xselect.c (Fx_register_dnd_atom):
15197 Simplify previous changes by using xpalloc.
15199 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15200 since either will do and ptrdiff_t is convenient with xpalloc.
15202 * charset.c (charset_table_size)
15203 (struct charset_sort_data.priority): Now ptrdiff_t.
15204 (charset_compare): Don't overflow if priorities differ greatly.
15205 (Fsort_charsets): Don't assume list length fits in int.
15206 Check for size-calculation overflow when allocating sort data.
15207 (syms_of_charset): Allocate an initial charset table that is
15208 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15210 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15212 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15213 The actual value is always <= INT_MAX, and leaving it unsigned made
15214 overflow checking harder.
15216 * dispextern.h (struct glyph_matrix.rows_allocated)
15217 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15218 with xpalloc. The values are still always <= INT_MAX.
15220 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15222 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15223 (SAFE_NALLOCA): New macro.
15225 * region-cache.c (struct boundary.pos, find_cache_boundary)
15226 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15227 (set_cache_region, invalidate_region_cache)
15228 (revalidate_region_cache, know_region_cache, region_cache_forward)
15229 (region_cache_backward, pp_cache):
15230 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15231 so that ptrdiff_t * can be passed to xpalloc.
15232 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15233 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15234 (pp_cache): Don't assume cache_len fits in int.
15235 * region-cache.h: Adjust extern decls to match.
15237 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15238 EMACS_INT, since either will do, for xpalloc.
15240 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15241 (xnmalloc, xnrealloc, xpalloc): New functions.
15243 * bidi.c (bidi_shelve_header_size): New constant.
15244 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15245 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15247 * bidi.c (bidi_cache_shrink):
15248 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15250 Don't update size of array until after memory allocation succeeds,
15251 because xmalloc/xrealloc may not return.
15252 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15253 now that we have proper integer overflow checking.
15254 (record_overlay_string, overlay_strings): Catch overflows when
15255 calculating size of overlay_str_buf.
15257 * callproc.c (Fcall_process): Check for size overflow when
15258 calculating size of args2.
15259 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15260 Normally we prefer signed values, but sticking with ptrdiff_t would
15261 require adding more-complicated checks.
15263 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15264 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15265 Redo buffer-overflow calculations to avoid integer overflow.
15266 Add a FIXME comment where memory seems to be over-allocated.
15268 * character.c (Fstring): Check for size-calculation overflow.
15270 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15271 unnecessary integer overflow. Check for size overflow.
15272 (encode_coding_object): Don't update size until xmalloc succeeds.
15274 * composite.c (get_composition_id): Check for overflow in glyph
15275 length calculations.
15277 Integer and memory overflow fixes for display code.
15278 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15279 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15280 (scrolling_window): Check for overflow in size calculations.

15292 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15293 (get_doc_string): Check for size calculation overflow.
15294 Don't update size until allocation succeeds.
15295 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15296 EMACS_INT, where ptrdiff_t will do.
15297 (Fsubstitute_command_keys): Check for string overflow.
15299 * editfns.c (set_time_zone_rule): Don't assume environment length
15301 (message_length): Now ptrdiff_t, not int.
15302 (Fmessage_box): Don't update size until allocation succeeds.
15303 Don't assume message length fits in int.
15304 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15306 * emacs.c (main): Do not reallocate argv, since there is a null at
15307 the end that can be overwritten, and this way there's no need to
15308 worry about size-calculation overflow.
15309 (sort_args): Check for size-calculation overflow.
15311 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15313 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15315 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15316 (x_set_scroll_bar_width, x_figure_window_size):
15317 Check for integer overflow.
15318 (x_set_alpha): Do not assume XINT fits in int.
15320 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15321 This is for the members text_lines, text_cols, total_lines, total_cols,
15322 where the system imposes an 'int' limit.
15324 * fringe.c (Fdefine_fringe_bitmap):
15325 Don't update size until alloc works.
15327 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15328 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15330 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15331 Check for size-calculation overflow.
15332 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15333 do, as we prefer signed integers.
15334 (id_to_widget.max_size, id_to_widget.used)
15335 (xg_store_widget_in_map, xg_remove_widget_from_map)
15336 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15337 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15338 Use and return ptrdiff_t, not int.
15339 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15340 * gtkutil.h: Change prototypes to match the above.
15342 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15343 are duplicate now that they've been promoted to lisp.h.
15344 (x_allocate_bitmap_record, x_alloc_image_color)
15345 (make_image_cache, cache_image, xpm_load):

15359 calculations. Don't update size until allocation succeeds.
15360 Redo calculations to avoid overflow.

15389 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15390 for command line length. Do not attempt to address one before the
15391 beginning of an array, as that's not portable.
15393 * term.c (max_frame_lines): Remove; unused.
15394 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15396 (encode_terminal_code, calculate_costs): Check for size

15403 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15404 subtracting pointers.

15419 Use ptrdiff_t, not int, for sizes.
15420 (Finternal_make_lisp_face, cache_face):
15421 Check for size calculation overflow.
15422 (cache_face): Treat size calculation overflows as if they were
15423 memory exhaustion (the usual treatment), rather than aborting.
15425 * xfns.c (x_encode_text, x_set_name_internal)
15426 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15427 sizes, since they can exceed INT_MAX in size. Check for size

15432 Don't update size until alloc done.
15434 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15435 as sprintf is limited to int lengths.
15437 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15438 (X_LONG_MIN): New macros.
15439 Use them to make the following changes clearer.
15440 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15441 This change doesn't affect the value now, but it may help remind
15442 future maintainers not to raise the value too much later.
15443 (SELECTION_QUANTUM): Remove, replacing with ...
15444 (selection_quantum): ... new function, which avoids overflow.
15446 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15447 assumption that selection length fits in 'int'.

15460 (lisp_data_to_selection_data, x_property_data_to_lisp):

15464 Don't store size until memory allocation succeeds.
15465 (x_get_window_property): Plug memory leak on memory exhaustion.
15466 Don't double-block input; malloc is safe here. Don't assume 2**34
15467 - 4 fits in unsigned long. Add an xassert to check
15468 XGetWindowProperty overflow. Be more careful about overflow
15469 calculations, and distinguish size from memory overflow better.
15470 (receive_incremental_selection): When tracing, don't assume
15471 unsigned int is less than INT_MAX.
15472 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15473 harmful) conversions of unsigned short to int.
15474 (lisp_data_to_selection_data): Don't assume that integers
15475 in the range -65535 through -1 fit in an X unsigned short.
15476 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15477 result parameters unless successful. Rely on cons_to_unsigned
15478 to report problems with elements; the old code wasn't right anyway.
15479 (x_check_property_data): Check for int overflow; we cannot use
15480 a wider type due to X limits.
15481 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

15513 * lisp.h (hash_lookup, hash_put):
15514 * minibuf.c (Ftest_completion):
15515 Use ptrdiff_t for hash table indexes, not int (which is too
15516 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15517 32-bit --with-wide-int hosts).
15519 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15520 Add a FIXME comment about memory leaks.
15521 (syms_of_charset): Don't assume xmalloc returns.

15528 with outlandish widths.
15529 * character.h (sanitize_tab_width): Rename from sanitize_width,
15530 now that we have two such functions. All uses changed.

15551 exceed limits imposed by XClientMessageEvent, as well as the usual
15552 ptrdiff_t and size_t limits.
15554 * keyboard.c: Overflow, signedness and related fixes.
15555 (make_lispy_movement): Use same integer type in forward decl
15556 that is used in the definition.
15557 (read_key_sequence, keyremap_step):
15558 Change bufsize argument back to int, undoing my 2011-03-30 change.
15559 We prefer signed types, and int is wide enough here.
15560 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15561 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15562 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15563 length, not size_t. Use ptrdiff_t for index, not int.
15564 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15565 possibility of integer overflow.
15567 Overflow, signedness and related fixes for images.

15593 Prefer int to unsigned where either will do.
15594 (tiff_handler): New function, combining the cores of the
15595 old tiff_error_handler and tiff_warning_handler.
15596 This function is rewritten to use vsnprintf and thereby avoid
15597 stack buffer overflows. It uses only the features of vsnprintf
15598 that are common to both POSIX and native Microsoft.
15599 (tiff_error_handler, tiff_warning_handler): Use it.
15600 (tiff_load, gif_load, imagemagick_load_image):
15601 Don't assume :index value fits in 'int'.
15602 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15603 (imagemagick_load_image): Check that crop parameters fit into
15604 the integer types that MagickCropImage accepts. Don't assume
15605 Vimagemagick_render_type has a nonnegative value. Don't assume
15606 size_t fits in 'long'.
15607 (gs_load): Use printmax_t to print the widest integers possible.

15621 (handle_single_display_spec): If the display spec is of the form
15622 `(space ...)', and specifies display in the text area, return 2
15624 (try_cursor_movement): Check for the need to scroll more
15625 accurately, and prefer exact match for point under bidi.
15626 Don't advance `row' beyond the last row of the window.

15647 positioning on the newline at EOL of R2L text within L2R
15648 paragraph, and vice versa.
15649 (try_cursor_movement): Check continued rows, in addition to
15650 continuation rows. Fixes unwarranted scroll when point enters a
15651 continued line of R2L text within an L2R paragraph, or vice versa.
15652 (cursor_row_p): Consider the case of point being equal to
15653 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

15679 * xdisp.c (redisplay_window): When computing centering_position,
15680 account for the height of the header line. (Bug#8874)
15682 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15683 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15684 candidate is selected by the mouse, and that candidate has a
15685 composed character under the mouse.
15687 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15688 coordinates reported by pos-visible-in-window-p for a composed
15689 character in column zero.

15698 consider it a hit if to_charpos is anywhere in the range of the
15699 composed buffer positions.
15701 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15703 * image.c (gif_load): Don't assume that each subimage has the same
15704 dimensions as the base image. Handle disposal method that is
15705 "undefined" by the gif spec (Bug#9335).
15707 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15709 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15715 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15716 from an Org mode buffer to a Speedbar frame.
15718 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15719 a composition, take its buffer position from IT->cmp_it.charpos.
15720 Fixes cursor positioning at the beginning of a line that begins
15721 with a composed character.
15723 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15725 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15726 character bidirectional type, use STRONG_L instead. Fixes crashes
15727 in a buffer produced by `describe-categories'.
15729 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15730 members before the level stack, so they would be saved and
15731 restored when copying iterator state. Fixes incorrect reordering
15732 around TABs covered by display properties.

15867 buffer/string position, to be restored by pop_it. Fix flags in
15868 the iterator structure wrt the object coming from a display
15869 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15870 properties. (Bug#9284)

16057 * nsfont.m (nsfont_open): Remove assignment to voffset and
16058 unnecessary vars hshink, expand, hd, full_height, min_height.
16059 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16061 * nsterm.h (nsfont_info): Remove voffset field.
16063 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16065 Implement strike-through and overline on NextStep (Bug#8863).
16067 * nsfont.m (nsfont_open): Use underline position provided by font,
16068 instead of hard-coded value of 2.
16069 (nsfont_draw): Call ns_draw_text_decoration instead.
16071 * nsterm.h: Add declaration for ns_draw_text_decoration.
16073 * nsterm.m (ns_draw_text_decoration): New function for drawing
16074 underline, overline, and strike-through.
16075 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16076 ns_draw_text_decoration. Change treatment of cursor drawing to
16077 accommodate underlining, etc.
16079 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16081 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16084 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16086 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16087 Without this fix, if a signal arrives just after memory fills up,
16088 'malloc' might be invoked reentrantly.
16090 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16091 In other words, assume that every image size is allowed, on non-X
16092 hosts. This assumption is probably wrong, but it lets Emacs compile.
16094 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16096 * regex.c (re_iswctype): Convert return values to boolean.
16098 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16100 * xdisp.c (compute_display_string_pos): Don't use cached display
16101 string position if the buffer had its restriction changed.
16104 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16106 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16108 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16110 Integer signedness and overflow and related fixes. (Bug#9079)
16112 * bidi.c: Integer size and overflow fixes.
16113 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16114 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16115 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16116 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16117 (bidi_find_other_level_edge):
16118 Use ptrdiff_t instead of EMACS_INT where either will do.
16119 This works better on 32-bit hosts configured --with-wide-int.
16120 (bidi_cache_ensure_space): Check for size-calculation overflow.
16121 Use % rather than repeated addition, for better worst-case speed.
16122 Don't set bidi_cache_size until after xrealloc returns, because it
16124 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16125 (bidi_cache_ensure_space): Also check that the bidi cache size
16126 does not exceed that of the largest Lisp string or buffer. See Eli
16127 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16129 * alloc.c (__malloc_size_t): Remove.
16130 All uses replaced by size_t. See Andreas Schwab's note
16131 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16133 * image.c: Improve checking for integer overflow.
16134 (check_image_size): Assume that f is nonnull, since
16135 it is always nonnull in practice. This is one less thing to
16136 worry about when checking for integer overflow later.
16137 (x_check_image_size): New function, which checks for integer
16138 overflow issues inside X.
16139 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16140 This removes the need for a memory_full check.
16141 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16142 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16143 (xbm_read_bitmap_data): Change locals back to 'int', since
16144 their values must fit in 'int'.
16145 (xpm_load_image, png_load, tiff_load):
16146 Invoke x_create_x_image_and_pixmap earlier,
16147 to avoid much needless work if the image is too large.
16148 (tiff_load): Treat overly large images as if
16149 x_create_x_image_and_pixmap failed, not as malloc failures.
16150 (gs_load): Use x_check_image_size.
16152 * gtkutil.c: Omit integer casts.
16153 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16154 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16156 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16158 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16159 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16160 would wrongly return t on a 64-bit host.
16162 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16163 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16164 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16165 and therefore cause GCC to emit a bogus diagnostic in some cases.
16167 * image.c: Integer signedness and overflow and related fixes.
16168 This is not an exhaustive set of fixes, but it's time to
16169 record what I've got.
16170 (lookup_pixel_color, check_image_size): Remove redundant decls.
16171 (check_image_size): Don't assume that arbitrary EMACS_INT values
16172 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16173 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16174 (tiff_load, imagemagick_load_image):
16175 Check for overflow in size calculations.
16176 (x_create_x_image_and_pixmap): Remove unnecessary test for
16177 xmalloc returning NULL; that can't happen.
16178 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16179 (xpm_color_bucket): Use better integer hashing function.
16180 (xpm_cache_color): Don't possibly over-allocate memory.
16181 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16182 (gif_memory_source):
16183 Use ptrdiff_t, not int or size_t, to record sizes.
16184 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16185 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16186 either works, as we prefer signed integers.
16187 (tiff_read_from_memory, tiff_write_from_memory):
16188 Return tsize_t, not size_t, since that's what the TIFF API wants.
16189 (tiff_read_from_memory): Don't fail simply because the read would
16190 go past EOF; instead, return a short read.
16191 (tiff_load): Omit no-longer-needed casts.
16192 (Fimagemagick_types): Don't assume size fits into 'int'.
16194 Improve hashing quality when configured --with-wide-int.
16195 * fns.c (hash_string): New function, taken from sxhash_string.
16196 Do not discard information about ASCII character case; this
16197 discarding is no longer needed.
16198 (sxhash-string): Use it. Change sig to match it. Caller changed.
16199 * lisp.h: Declare it.
16200 * lread.c (hash_string): Remove, since we now use fns.c's version.
16201 The fns.c version returns a wider integer if --with-wide-int is
16202 specified, so this should help the quality of the hashing a bit.
16204 * emacs.c: Integer overflow minor fix.
16205 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16206 Define only if GNU_LINUX.
16207 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16209 * dispnew.c: Integer signedness and overflow fixes.
16210 Remove unnecessary forward decls, that were a maintenance hassle.
16211 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16213 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16214 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16215 (prepare_desired_row, line_draw_cost):
16216 Use int, not unsigned, where either works.
16217 (save_current_matrix, restore_current_matrix):
16218 Use ptrdiff_t, not size_t, where either works.
16219 (init_display): Check for overflow more accurately, and without
16220 relying on undefined behavior.
16222 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16223 Remove, replacing with the new symbols in lisp.h. All uses changed.
16224 * fileio.c (make_temp_name):
16225 * filelock.c (lock_file_1, lock_file):
16226 * xdisp.c (message_dolog):
16227 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16228 Use pMd etc. instead.
16229 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16230 replacing the pWIDE etc. symbols removed from editfns.c.
16232 * keyboard.h (num_input_events): Now uintmax_t.
16233 This is (very slightly) less likely to mess up due to wraparound.
16236 * buffer.c: Integer signedness fixes.
16237 (alloc_buffer_text, enlarge_buffer_text):
16238 Use ptrdiff_t rather than size_t when either will do, as we prefer
16241 * alloc.c: Integer signedness and overflow fixes.
16242 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16243 (__malloc_size_t): Default to size_t, not to int.
16244 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16245 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16246 Prefer ptrdiff_t to size_t when either would do, as we prefer
16248 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16249 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16250 Now const. Initialize with values that are in range even if char
16252 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16253 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16254 These functions do the right thing with sizes > 2**32.
16255 (check_depth): Now ptrdiff_t, not int.
16256 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16257 Adjust to new way of storing sizes. Check for size overflow bugs
16259 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16260 slightly wrong anyway, as it missed one instance of
16261 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16262 (refill_memory_reserve): Omit needless cast to size_t.
16263 (mark_object_loop_halt): Mark as externally visible.
16265 * xselect.c: Integer signedness and overflow fixes.
16266 (Fx_register_dnd_atom, x_handle_dnd_message):
16267 Use ptrdiff_t, not size_t, since we prefer signed.
16268 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16269 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16270 x_dnd_atoms_size and x_dnd_atoms_length.
16272 * doprnt.c: Prefer signed to unsigned when either works.
16274 * doprnt.c (doprnt):
16276 * xdisp.c (vmessage):
16277 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16278 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16279 prefer signed arithmetic to avoid comparison confusion.
16280 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16281 but is a bit tricky.
16283 Assume freestanding C89 headers, string.h, stdlib.h.
16284 * data.c, doprnt.c, floatfns.c, print.c:
16285 Include float.h unconditionally.
16286 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16287 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16288 * regex.c: Likewise for stddef.h, string.h.
16289 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16290 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16291 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16292 (STDC_HEADERS): Remove obsolete defines.
16293 * sysdep.c: Include limits.h unconditionally.
16295 Assume support for memcmp, memcpy, memmove, memset.
16296 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16297 * regex.c (memcmp, memcpy):
16298 Remove; we assume C89 now.
16300 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16301 (__malloc_safe_bcopy): Remove; no longer needed.
16303 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16304 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16305 well either way, and we prefer signed to unsigned.
16307 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16309 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16310 closes the connection while we're reading (bug#9182).
16312 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16314 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16315 are specified (Bug#9168).
16317 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16319 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16320 Found by GCC static checking and --with-wide-int on a 32-bit host.
16322 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16324 * xdisp.c (compute_display_string_pos): Fix logic of caching
16325 previous display string position. Initialize cached_prev_pos to
16326 -1. Fixes slow-down at the beginning of a buffer.
16328 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16330 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16331 for attrs[LFACE_FONTSET_INDEX].
16333 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16335 * xml.c (parse_region): Remove unused local
16336 that was recently introduced.
16338 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16340 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16341 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16343 * xdisp.c (move_it_in_display_line_to): Record the best matching
16344 position for TO_CHARPOS while scanning the line, and restore it on
16345 exit if none of the characters scanned was an exact match.
16346 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16347 when exact match is impossible due to invisible text, and the
16348 lines are truncated.
16350 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16352 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16355 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16357 Fix a significant slow-down of cursor motion with C-n, C-p,
16358 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16359 auto-repeat under bidi redisplay in fontified buffers.
16360 * xdisp.c (compute_stop_pos_backwards): New function.
16361 (next_element_from_buffer): Call compute_stop_pos_backwards to
16362 find a suitable prev_stop when we find ourselves before
16364 (reseat): Don't look for prev_stop, as that could mean a very long
16366 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16367 <cached_disp_overlay_modiff>: Cache for last found display string
16369 (compute_display_string_pos): Return the cached position if asked
16370 about the same buffer in the same area of character positions, and
16371 the buffer wasn't changed since the time the display string
16372 position was cached.
16374 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16376 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16377 is an integer, which is important for empty lines. (Bug#9149)
16379 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16381 * frame.c (Fmodify_frame_parameters): In tty case, update the
16382 default face if necessary (Bug#4238).
16384 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16386 * editfns.c (Fstring_to_char): No need to explain what a character
16387 is in the docstring (Bug#6576).
16389 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16391 * xml.c (parse_region): Make sure we always return a tree.
16393 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16395 * xml.c (parse_region): If a document contains only comments,
16398 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16400 * xml.c (make_dom): Return comments, too.
16402 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16405 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16406 and the surrounding thread.
16407 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16408 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16409 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16411 * s/openbsd.h (BROKEN_SIGIO): Define.
16412 * unexelf.c (unexec) [__OpenBSD__]:
16413 Don't update the .mdebug section of the Alpha COFF symbol table.
16415 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16417 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16420 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16422 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16423 This fixes some race conditions on the permissions of any newly
16426 * alloc.c (valid_pointer_p): Use pipe, not open.
16427 This fixes some permissions issues when debugging.
16429 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16430 If fchown fails to set both uid and gid, try to set just gid,
16431 as that is sometimes allowed. Adjust the file's mode to eliminate
16432 setuid or setgid bits that are inappropriate if fchown fails.
16434 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16436 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16437 to compare Lisp_Objects.
16438 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16439 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16440 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16442 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16444 * lread.c (read_integer): Unread even EOF character.
16445 (read1): Likewise. Properly record start position of symbol.
16447 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16448 symbol character follows.
16450 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16452 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16453 This works around a problem with the previous change to Fcopy_file.
16454 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16455 and without this change, GCC might complain about discarding
16456 fchown's return value.
16458 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16460 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16462 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16464 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16466 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16468 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16469 it's used from the C level.
16471 * process.c: Use the same condition for POLL_FOR_INPUT in both
16472 keyboard.c and process.c (bug#1858).
16474 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16476 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16477 (Fgnutls_boot): Use it.
16479 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16481 * doc.c (Fsubstitute_command_keys): Revert last change.
16483 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16485 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16486 quotes the next character, and doesn't affect other longer
16487 sequences (bug#8935).
16489 * lread.c (syms_of_lread): Clarify that is isn't only
16490 `eval-buffer' and `eval-defun' that's affected by
16491 `lexical-binding' (bug#8460).
16493 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16495 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16496 bidi redisplay when a line includes both an image and is truncated.

16500 Fix minor problems found by static checking.
16501 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16502 (elsz): Now a signed constant, not a size_t var. We prefer signed
16503 types to unsigned, to avoid integer comparison confusion. Without
16504 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16505 "cannot optimize loop, the loop counter may overflow", a symptom
16507 * indent.c (Fvertical_motion): Mark locals as initialized.
16508 * xdisp.c (reseat_to_string): Fix pointer signedness issue.

16525 (compute_display_string_end): Accept additional argument STRING.
16526 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.

16533 buffer position was specified. Initialize paragraph_embedding to
16535 (reseat_to_string): Initialize the bidi iterator.
16536 (display_string): If we need to ignore text properties of
16537 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16538 original value of -1 will not work with bidi.)

16548 Fix calculation of the object to scan. Fixes an error when using

16551 base_level_stop; instead, set base_level_stop to BEGV.
16552 Fixes crashes in vertical-motion.
16553 (next_element_from_buffer): Improve commentary for when
16554 the iterator is before prev_stop.
16555 (init_iterator): Initialize bidi_p from the default value of
16556 bidi-display-reordering, not from buffer-local value. Use the
16557 buffer-local value only if initializing for buffer iteration.
16558 (handle_invisible_prop): Support invisible properties on strings
16559 that are being bidi-reordered.

16581 (display_menu_bar): Force left-to-right direction. Add a FIXME
16582 comment for making that be controlled by a user option.

16596 pushed the iterator stack, restore the internal state of the bidi
16597 iterator by calling bidi_pop_it same number of times.
16598 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,

16600 instead, set the first_elt flag in the bidi iterator, to produce
16602 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16603 (push_display_prop): xassert that we are iterating a buffer.

16607 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16608 correctly. Don't assume unibyte strings are not bidi-reordered.

16617 property. Fix a typo in popping stretch info. Add an assertion
16618 for verifying that the iterator position is in sync with the bidi
16620 (handle_single_display_spec, get_overlay_strings_1)

17036 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17073 Random fixes. E.g., (random) never returned negative values.
17074 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17075 subseconds part to the entropy, as that's a bit more random.
17076 Prefer signed to unsigned, since the signedness doesn't matter and
17077 in general we prefer signed. When given a limit, use a
17078 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17079 latter isn't right if USE_2_TAGS_FOR_INTS.
17080 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17081 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17093 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17094 This is more efficient than Ffile_directory_p and avoids a minor race.

17098 * buffer.c (Foverlay_put): Say what the return value is
17101 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17105 error be more correct.
17107 * fns.c (Frequire): Remove the mention of the .gz files, since

17121 Qgnutls_bootprop_verify_error (which is no longer used).
17123 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17124 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17125 Also (re)move comments that are misplaced or no longer relevant.
17127 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17129 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17226 * eval.c (struct backtrace): Simplify and port the data structure.
17227 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17228 signed bit field, as this assumption is not portable and it makes
17229 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17230 "char debug_on_exit : 1" as this is not portable either; instead,
17231 use the portable "unsigned int debug_on_exit : 1". Remove unused
17232 member evalargs. Remove obsolete comments about cc bombing out.
17234 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17392 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
17394 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
17396 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17398 Integer and buffer overflow fixes (Bug#8873).
17400 * print.c (printchar, strout): Check for string overflow.
17401 (PRINTPREPARE, printchar, strout):
17402 Don't set size unless allocation succeeds.
17404 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17405 for sizes. Check for string overflow more accurately.
17406 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17408 * macros.c: Integer and buffer overflow fixes.
17409 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17410 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17411 Use ptrdiff_t, not int, for sizes.
17412 Don't increment bufsize until after realloc succeeds.
17413 Check for size-calculation overflow.
17414 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17416 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17418 * lread.c: Integer overflow fixes.
17419 (read_integer): Radix is now EMACS_INT, not int,
17420 to improve quality of diagnostics for out-of-range radices.
17421 Calculate buffer size correctly for out-of-range radices.
17422 (read1): Check for integer overflow in radices, and in
17423 read-circle numbers.
17424 (read_escape): Avoid int overflow.
17425 (Fload, openp, read_buffer_size, read1)
17426 (substitute_object_recurse, read_vector, read_list, map_obarray):
17427 Use ptrdiff_t, not int, for sizes.
17428 (read1): Use EMACS_INT, not int, for sizes.
17429 Check for size overflow.
17431 * image.c (cache_image): Check for size arithmetic overflow.
17433 * lread.c: Integer overflow issues.
17434 (saved_doc_string_size, saved_doc_string_length)
17435 (prev_saved_doc_string_size, prev_saved_doc_string_length):
17436 Now ptrdiff_t, not int.

17438 out-of-range doc string lengths.
17439 (read_list): Don't assume file position fits in int.
17440 (read_escape): Check for hex character overflow.
17442 2011-06-22 Leo Liu <sdl.web@gmail.com>
17444 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17445 Move to minibuffer.el.
17447 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17449 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17450 The following patches are for when GLYPH_DEBUG && !XASSERT.
17451 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17452 * dispnew.c (flush_stdout):
17453 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17454 Mark as externally visible.
17455 * dispnew.c (check_window_matrix_pointers): Now static.
17456 * dispnew.c (window_to_frame_vpos):
17457 * xfns.c (unwind_create_frame):
17458 * xterm.c (x_check_font): Remove unused local.
17459 * scroll.c (CHECK_BOUNDS):
17460 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17461 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17462 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17463 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17464 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17466 (debug_method_add): Use va_list and vsprintf rather than relying
17467 on undefined behavior with wrong number of arguments.
17468 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17469 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17470 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17471 since we're not interested in debugging glyphs with old libraries.
17472 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17473 GCC 4.6.0's static checking.
17475 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17477 Integer overflow and signedness fixes (Bug#8873).
17478 A few related buffer overrun fixes, too.

17486 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17487 (x_create_bitmap_from_xpm_data):
17488 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17489 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17491 * xfaces.c (load_pixmap):
17492 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17493 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17494 (.bitmaps_last, struct x_output.icon_bitmap):
17495 Use ptrdiff_t, not int, for bitmap indexes.
17496 (x_allocate_bitmap_record): Check for size overflow.
17497 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17499 Use ptrdiff_t, not int, for overlay counts.
17500 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17501 * editfns.c (overlays_around, get_pos_property):
17502 * textprop.c (get_char_property_and_overlay):
17503 * xdisp.c (next_overlay_change, note_mouse_highlight):
17504 * xfaces.c (face_at_buffer_position):
17505 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17506 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17507 (Fnext_overlay_change, Fprevious_overlay_change)
17508 (mouse_face_overlay_overlaps, Foverlays_in):
17509 Use ptrdiff_t, not int, for sizes.
17510 (overlays_at, overlays_in): Check for size-calculation overflow.
17512 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17514 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17515 (x_session_initialize): Do not assume string length fits in int.
17517 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17518 This is unlikely, but can occur if DPI is outlandish.
17520 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17521 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17523 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17524 * xrdb.c (magic_file_p, search_magic_path):
17525 Omit last arg SUFFIX; it was always 0. All callers changed.
17526 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17528 * xfont.c (xfont_match): Avoid need for strlen.
17530 * xfns.c: Don't assume strlen fits in int.
17531 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17533 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17534 not unsigned long, as we prefer signed integers. All callers changed.
17535 Detect integer overflow in repeat count.
17536 (message_dolog): Don't assume print length fits in 39 bytes.
17537 (display_mode_element): Don't assume strlen fits in int.
17539 * termcap.c: Don't assume sizes fit in int and never overflow.
17540 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17541 (gobble_line): Check for size-calculation overflow.
17543 * minibuf.c (Fread_buffer):
17544 * lread.c (intern, intern_c_string):
17545 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17546 Don't assume string length fits in int.
17548 * keyboard.c (parse_tool_bar_item):
17549 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17551 * font.c: Don't assume string length fits in int.
17552 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17553 Use ptrdiff_t, not int.
17554 (font_intern_prop): Don't assume string length fits in int.
17555 Don't assume integer property fits in fixnum.
17556 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17558 * filelock.c: Fix some buffer overrun and integer overflow issues.
17559 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17560 Reformulate so as not to need the command string.
17561 Invoke gzip -cd rather than gunzip, as it's more portable.
17562 (lock_info_type, lock_file_1, lock_file):
17563 Don't assume pid_t and time_t fit in unsigned long.
17564 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17565 (current_lock_owner): Prefer signed type for sizes.
17566 Use memcpy, not strncpy, where memcpy is what is really wanted.
17567 Don't assume (via atoi) that time_t and pid_t fit in int.
17568 Check for time_t and/or pid_t out of range, e.g., via a network share.
17569 Don't alloca where an auto var works fine.
17571 * fileio.c: Fix some integer overflow issues.
17572 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17573 Don't assume string length fits in int.
17574 (directory_file_name): Don't assume string length fits in long.
17575 (make_temp_name): Don't assume pid fits in int, or that its print
17576 length is less than 20.
17578 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17580 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17582 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17584 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17585 We prefer signed integers, even for size calculations.
17587 * emacs.c: Don't assume string length fits in 'int'.
17588 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17589 (main): Don't invoke strlen when not needed.
17591 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17592 (XD_DEBUG_MESSAGE): Don't waste a byte.
17594 * callproc.c (getenv_internal_1, getenv_internal)
17595 (Fgetenv_internal):
17596 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17598 * lread.c (invalid_syntax): Omit length argument.
17599 All uses changed. This doesn't fix a bug, but it simplifies the
17600 code away from its former Hollerith-constant appearance, and it's
17601 one less 'int' to worry about when looking at integer-overflow issues.
17602 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17604 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17605 This didn't break anything, but it didn't help either.
17606 It's confusing to put a bogus integer in a place where the actual
17607 value does not matter.
17608 (LIST_END_P): Remove unused macro and its bogus comment.
17609 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17611 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17612 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17614 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17615 We prefer signed types, and the value cannot exceed the EMACS_INT
17616 range anyway (because otherwise the length would not be representable).
17617 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17618 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17619 This avoids a GCC warning when WIDE_EMACS_INT.
17621 * indent.c (sane_tab_width): New function.
17622 (current_column, scan_for_column, Findent_to, position_indentation)
17623 (compute_motion): Use it. This is just for clarity.
17624 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17626 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17628 * lisp.h (lint_assume): New macro.
17629 * composite.c (composition_gstring_put_cache):
17630 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17632 * editfns.c, insdel.c:
17633 Omit unnecessary forward decls, to simplify future changes.
17635 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17637 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17639 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17640 Use much-faster test for byte-length change.
17641 Don't assume string byte-length fits in 'int'.
17642 Check that character arg fits in 'int'.
17643 (mapcar1): Declare byte as byte, for clarity.
17645 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17647 * fns.c (concat): Catch string overflow earlier.
17648 Do not rely on integer wraparound.
17650 * dispextern.h (struct it.overlay_strings_charpos)
17651 (struct it.selective): Now EMACS_INT, not int.
17652 * xdisp.c (forward_to_next_line_start)
17653 (back_to_previous_visible_line_start)
17654 (reseat_at_next_visible_line_start, next_element_from_buffer):
17655 Don't arbitrarily truncate the value of 'selective' to int.
17657 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17659 * composite.c: Don't truncate sizes to 'int'.
17660 (composition_gstring_p, composition_reseat_it)
17661 (composition_adjust_point): Use EMACS_INT, not int.
17662 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17663 not EMACS_UINT, for indexes.
17665 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17667 * buffer.c: Include <verify.h>.
17668 (struct sortvec.priority, struct sortstr.priority):
17669 Now EMACS_INT, not int.
17670 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17671 (struct sortstr.size, record_overlay_string)
17672 (struct sortstrlist.size, struct sortlist.used):
17673 Don't truncate size to int.
17674 (record_overlay_string): Check for size-calculation overflow.
17675 (init_buffer_once): Check at compile-time, not run-time.
17677 2011-06-22 Jim Meyering <meyering@redhat.com>
17679 Don't leak an XBM-image-sized buffer
17680 * image.c (xbm_load): Free the image buffer after using it.
17682 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17685 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17686 that Sun C diagnosed.
17687 * fns.c (secure_hash): Fix pointer signedness issue.
17688 * intervals.c (static_offset_intervals): New function.
17689 (offset_intervals): Use it.
17691 2011-06-21 Leo Liu <sdl.web@gmail.com>
17694 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17697 * fns.c (secure_hash): Rename from crypto_hash_function and change
17698 the first arg to accept symbols.
17699 (Fsecure_hash): New primitive.
17700 (syms_of_fns): New symbols.
17702 2011-06-20 Deniz Dogan <deniz@dogan.se>
17704 * process.c (Fset_process_buffer): Clarify return value in
17707 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17709 * dispnew.c (add_window_display_history): Use BVAR.
17711 * xdisp.c (debug_method_add): Use BVAR.
17712 (check_window_end, dump_glyph_matrix, dump_glyph)
17713 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17715 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17718 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17719 check till after the cache is created in init_frame_faces.
17721 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17723 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17725 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17727 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17728 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17729 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17731 Improve buffer-overflow checking (Bug#8873).
17732 * fileio.c (Finsert_file_contents):
17733 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17734 Remove the old (too-loose) buffer overflow checks.
17735 They weren't needed, since make_gap checks for buffer overflow.
17736 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17737 The old code merely checked for Emacs fixnum overflow, and relied
17738 on undefined (wraparound) behavior. The new code avoids undefined
17739 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17741 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17742 Tune. Don't use wider integers than needed. Don't use alloca.
17743 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17745 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17747 * insdel.c, lisp.h (buffer_overflow): New function.
17748 (insert_from_buffer_1, replace_range, replace_range_2):
17749 * insdel.c (make_gap_larger):
17750 * editfns.c (Finsert_char):
17751 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17753 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17755 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17757 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17759 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17760 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17762 * fileio.c: Don't assume EMACS_INT fits in off_t.
17763 (emacs_lseek): New static function.
17764 (Finsert_file_contents, Fwrite_region): Use it.
17765 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17767 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17769 * fns.c: Don't overflow int when computing a list length.
17770 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17771 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17772 truncation on 64-bit hosts. Check for QUIT every
17773 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17774 faster and is responsive enough.
17775 (Flength): Report an error instead of overflowing an integer.
17776 (Fsafe_length): Return a float if the value is not representable
17777 as a fixnum. This shouldn't happen except in contrived situations.
17778 (Fnthcdr, Fsort): Don't assume list length fits in int.
17779 (Fcopy_sequence): Don't assume vector length fits in int.
17781 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17782 (header_size, word_size): New constants.
17783 (allocate_vectorlike): Don't check size overflow here.
17784 (allocate_vector): Check it here instead, since this is the only
17785 caller of allocate_vectorlike that could cause overflow.
17786 Check that the new vector's length is representable as a fixnum.
17788 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17789 The previous code was bogus. For example, next_almost_prime (32)
17790 returned 39, which is undesirable as it is a multiple of 3; and
17791 next_almost_prime (24) returned 25, which is a multiple of 5 so
17792 why was the code bothering to check for multiples of 7?
17794 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17796 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17798 Variadic C functions now count arguments with ptrdiff_t.
17799 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17800 Back then I didn't know that the Emacs coding style prefers signed int.
17801 Also, in the meantime I found a few more instances where arguments
17802 were being counted with int, which may truncate counts on 64-bit
17803 machines, or EMACS_INT, which may be unnecessarily wide.
17804 * lisp.h (struct Lisp_Subr.function.aMANY)
17805 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17806 Arg counts are now ptrdiff_t, not size_t.
17807 All variadic functions and their callers changed accordingly.
17808 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17809 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17810 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17811 * callint.c (Fcall_interactively): Check arg count for overflow,
17812 to avoid potential buffer overrun. Use signed char, not 'int',
17813 for 'varies' array, so that we needn't bother to check its size
17814 calculation for overflow.
17815 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17816 * eval.c (apply_lambda):
17817 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17818 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17819 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17821 * callint.c (Fcall_interactively): Don't use index var as event count.
17823 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17824 * mem-limits.h (SIZE): Remove; no longer used.
17826 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17828 Remove unnecessary casts.
17829 * xterm.c (x_term_init):
17830 * xfns.c (x_set_border_pixel):
17831 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17832 These aren't needed now that we assume ANSI C.
17834 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17835 It's more likely to cause problems (due to unsigned overflow)
17838 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17840 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17842 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17844 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17846 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17848 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17850 GLYPH_CODE_FACE returns EMACS_INT, not int.
17851 * dispextern.h (merge_faces):
17852 * xfaces.c (merge_faces):
17853 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17854 Don't assume EMACS_INT fits in int.
17856 * character.h (CHAR_VALID_P): Remove unused parameter.
17857 * fontset.c, lisp.h, xdisp.c: All uses changed.
17859 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17861 * fns.c (concat): Minor tuning based on overflow analysis.
17862 This doesn't fix any bugs. Use int to hold character, instead
17863 of constantly refetching from Emacs object. Use XFASTINT, not
17864 XINT, for value known to be a character. Don't bother comparing
17865 a single byte to 0400, as it's always less.
17867 * floatfns.c (Fexpt):
17868 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17870 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17873 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17875 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17876 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17877 incorrectly succeed when S was a string, because 4294967386 was
17878 truncated before it was used.
17880 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17881 Otherwise, an out-of-range integer could cause undefined behavior
17884 * composite.c: Use int, not EMACS_INT, for characters.
17885 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17886 EMACS_INT, for values that are known to be in character range.
17887 This doesn't fix any bugs but is the usual style inside Emacs and
17888 may generate better code on 32-bit machines.
17890 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17891 This is for reasons similar to the recent CHAR_STRING fix.
17892 * charset.c (Fencode_char): Check that character arg is actually
17893 a character. Pass an int to ENCODE_CHAR.
17894 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17895 wider than 'int', as a compile-time check to prevent future regressions
17898 * character.c (char_string): Remove unnecessary casts.
17900 Make sure a 64-bit char is never passed to CHAR_STRING.
17901 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17902 by silently ignoring the top 32 bits, allowing some values
17903 that were far too large to be valid characters.
17904 * character.h: Include <verify.h>.
17905 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17906 arguments are no wider than unsigned, as a compile-time check
17907 to prevent future regressions in this area.
17909 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17910 (Fsubst_char_in_region):
17912 * xdisp.c (decode_mode_spec_coding):
17913 Adjust to CHAR_STRING's new requirement.
17914 * editfns.c (Finsert_char, Fsubst_char_in_region):
17915 * fns.c (concat): Check that character args are actually
17916 characters. Without this test, these functions did the wrong
17917 thing with wildly out-of-range values on 64-bit hosts.
17919 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17920 These casts should not be needed on 32-bit hosts, either.
17921 * keyboard.c (read_char):
17922 * lread.c (Fload): Remove casts to unsigned.
17924 * lisp.h (UNSIGNED_CMP): New macro.
17925 This fixes comparison bugs on 64-bit hosts.
17926 (ASCII_CHAR_P): Use it.
17927 * casefiddle.c (casify_object):
17928 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17929 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17930 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17931 * dispextern.h (FACE_FROM_ID):
17932 * keyboard.c (read_char): Use UNSIGNED_CMP.
17934 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17935 not to EMACS_INT, to avoid GCC warning.
17937 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17939 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17940 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17941 isn't needed on 32-bit machines.
17943 * buffer.c (Fgenerate_new_buffer_name):
17944 Use EMACS_INT for count, not int.
17945 (advance_to_char_boundary): Return EMACS_INT, not int.
17947 * data.c (Qcompiled_function): Now static.
17949 * window.c (window_body_lines): Now static.
17951 * image.c (gif_load): Rename local to avoid shadowing.
17953 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17954 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17955 * alloc.c (make_save_value): Integer argument is now of type
17956 ptrdiff_t, not int.
17957 (mark_object): Use ptrdiff_t, not int.
17958 * lisp.h (pD): New macro.
17959 * print.c (print_object): Use it.
17961 * alloc.c: Use EMACS_INT, not int, to count objects.
17962 (total_conses, total_markers, total_symbols, total_vector_size)
17963 (total_free_conses, total_free_markers, total_free_symbols)
17964 (total_free_floats, total_floats, total_free_intervals)
17965 (total_intervals, total_strings, total_free_strings):
17966 Now EMACS_INT, not int. All uses changed.
17967 (Fgarbage_collect): Compute overall total using a double, so that
17968 integer overflow is less likely to be a problem. Check for overflow
17969 when converting back to an integer.
17970 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17971 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17972 These were 'int' variables that could overflow on 64-bit hosts;
17973 they were never used, so remove them instead of repairing them.
17974 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17975 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17976 Previously, this ceilinged at INT_MAX, but that doesn't work on
17978 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17980 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17981 (allocate_vectorlike): Check for ptrdiff_t overflow.
17982 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17983 when a (possibly-narrower) signed value would do just as well.
17984 We prefer using signed arithmetic, to avoid comparison confusion.
17986 * alloc.c: Catch some string size overflows that we were missing.
17987 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17988 for convenience in STRING_BYTES_MAX.
17989 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17990 The definition here is exact; the one in lisp.h was approximate.
17991 (allocate_string_data): Check for string overflow. This catches
17992 some instances we weren't catching before. Also, it catches
17993 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17994 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17995 and ptrdiff_t and EMACS_INT are both 64 bits.
17997 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17998 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17999 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18001 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18003 * alloc.c (Fmake_string): Check for out-of-range init.
18005 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18007 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18009 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18011 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18012 xg_get_default_scrollbar_width.
18014 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18015 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18016 (style_changed_cb): Call update_theme_scrollbar_width and call
18017 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18018 all frames (Bug#8505).
18019 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18020 Call gtk_window_set_resizable if HAVE_GTK3.
18021 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18022 and height if HAVE_GTK3 (Bug#8505).
18023 (scroll_bar_width_for_theme): New variable.
18024 (update_theme_scrollbar_width): New function.
18025 (xg_get_default_scrollbar_width): Move code to
18026 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18027 (xg_initialize): Call update_theme_scrollbar_width.
18029 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18031 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18033 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18035 * frame.c (make_frame): Call other_buffer_safely instead of
18038 * window.c (temp_output_buffer_show): Call display_buffer with
18039 second argument Vtemp_buffer_show_specifiers and reset latter
18040 immediately after the call.
18041 (Vtemp_buffer_show_specifiers): New variable.
18042 (auto_window_vscroll_p, next_screen_context_lines)
18043 (Vscroll_preserve_screen_position): Remove leading asterisks from
18046 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18048 Fix minor problems found by GCC 4.6.0 static checking.

18050 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18051 (record_buffer): Remove unused local.
18052 * frame.c (other_visible_frames, frame_buffer_list): Now static.

18064 * widgetprv.h (emacsFrameClassRec): Remove decl.
18065 * window.c (delete_deletable_window): Now returns void, since it
18066 wasn't returning anything.
18067 (compare_window_configurations): Remove unused locals.
18068 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18069 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.

18084 (syms_of_image): Use DEFSYM. New symbol `delay'.
18086 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18088 * window.c (delete_deletable_window): Re-add.
18089 (Fset_window_configuration): Rewrite to handle dead buffers and
18090 consequently deletable windows.
18091 (window_tree, Fwindow_tree): Remove. Supply functionality in
18093 (compare_window_configurations): Simplify code.

18104 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18105 Qclone_number. Remove external declaration of Qdelete_window.
18106 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18108 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18109 Run Qbuffer_list_update_hook if allowed.

18111 buffer list implementation.
18112 (other_buffer_safely): New function.

18223 * window.c: Remove declarations of Qwindow_size_fixed,
18224 window_min_size_1, window_min_size_2, window_min_size,
18225 size_window, window_fixed_size_p, enlarge_window, delete_window.
18226 Remove static from declaration of Qdelete_window, it's
18227 temporarily needed by Fbury_buffer.
18228 (replace_window): Don't assign orig_top_line and
18230 (Fdelete_window, delete_window): Remove. Window deletion is

18232 (window_loop): Remove DELETE_OTHER_WINDOWS case.
18233 Replace Fdelete_window calls with calls to Qdelete_window.
18234 (Fdelete_other_windows): Remove. Deleting other windows is

18607 value of a `display' property is a "replacing spec".
18608 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18609 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18639 * gnutls.c: Use Emacs's memory allocators.
18640 Without this change, the gnutls library would invoke malloc etc.
18641 directly, which causes problems on non-SYNC_INPUT hosts, and which
18642 runs afoul of improving memory_full behavior. (Bug#8761)
18643 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18644 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18645 xfree instead of the default malloc, realloc, free.
18646 (Fgnutls_boot): No need to check for memory allocation failure,
18647 since xmalloc does that for us.

18676 need to be updated by these changes.
18677 * fns.c (make_hash_table, maybe_resize_hash_table):
18678 Check for integer overflow with large hash tables.
18679 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18680 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18681 (SXHASH_REDUCE): New macro.
18682 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18683 Use it instead of discarding useful hash info with large hash values.
18684 (sxhash_float): New function.
18685 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18686 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18687 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18688 Rewrite to use FIXNUM_BITS, as this simplifies things.
18689 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18690 Adjust signatures to match updated version of code.
18691 (consing_since_gc): Now EMACS_INT, since a single hash table can
18692 use more than INT_MAX bytes.
18694 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18696 Make it possible to build with GCC-4.6+ -O2 -flto.
18698 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18700 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18702 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18703 Call minibuffer-inactive-mode.
18705 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18707 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18708 Update dependencies.
18710 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18712 * data.c (init_data): Remove code for UTS, this system is not
18715 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18717 Don't force ./temacs to start in terminal mode.
18719 * frame.c (make_initial_frame): Initialize faces in all cases, not
18720 only when CANNOT_DUMP is defined.
18721 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18723 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18725 * dispnew.c (add_window_display_history): Use const for the string
18726 pointer. Remove declaration, not needed.
18728 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18730 Use 'inline', not 'INLINE'.
18731 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18732 * alloc.c, fontset.c (INLINE): Remove.
18733 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18734 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18735 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18736 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18737 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18739 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18741 Make it possible to run ./temacs.
18743 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18744 syms_of_callproc does the same thing. Remove test for
18745 "initialized", do it in the caller.
18746 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18748 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18750 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18751 (read_minibuf): Use get_minibuffer.
18752 (syms_of_minibuf): Use DEFSYM.
18753 (Qmetadata): New var.
18754 * data.c (Qbuffer): Don't make it static.
18755 (syms_of_data): Use DEFSYM.
18757 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18759 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18760 (CCL_CODE_MIN): New macro.
18762 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18764 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18766 * eval.c (Qdebug): Now static.
18767 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18768 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18769 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18771 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18773 * image.c: Various fixes to ImageMagick code comments.
18774 (Fimagemagick_types): Doc fix.
18776 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18778 Minor fixes prompted by GCC 4.6.0 warnings.
18780 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18782 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18783 (x_clipboard_manager_save_all): Move extern decl to ...
18784 * xterm.h: ... here, so that it can be checked for consistency.
18786 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18788 * xselect.c (x_clipboard_manager_save_frame)
18789 (x_clipboard_manager_save_all): New functions.
18790 (Fx_clipboard_manager_save): Lisp function deleted.
18792 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18793 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18795 * xterm.h: Update prototype.
18797 2011-05-28 William Xu <william.xwl@gmail.com>
18799 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18800 exiting (Bug#8239).
18802 2011-05-28 Jim Meyering <meyering@redhat.com>
18804 Avoid a sign-extension bug in crypto_hash_function.
18805 * fns.c (to_uchar): Define.
18806 (crypto_hash_function): Use it to convert some newly-signed
18807 variables to unsigned, to avoid sign-extension bugs. For example,
18808 without this change, (md5 "truc") would evaluate to
18809 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18810 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18811 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18813 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18815 Integer overflow fixes.
18817 * dbusbind.c: Serial number integer overflow fixes.
18818 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18819 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18820 to hold a serial number that is too large for a fixnum.
18821 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18822 Check for serial numbers out of range. Decode any serial number
18823 that was so large that it became a float. (Bug#8722)
18825 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18826 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18827 Use XFASTINT rather than XUINT when numbers are nonnegative.
18828 (xd_append_arg, Fdbus_method_return_internal):
18829 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18830 arguments, check that Lisp number is nonnegative, rather than
18831 silently wrapping negative numbers around. (Bug#8722)
18832 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18835 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18837 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18839 ccl: Add integer overflow checks.
18840 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18841 (IN_INT_RANGE): New macros.
18842 (ccl_driver): Use them to check for integer overflow when
18843 decoding a CCL program. Many of the new checks are whether XINT (x)
18844 fits in int; it doesn't always, on 64-bit hosts. The new version
18845 doesn't catch all possible integer overflows, but it's an
18846 improvement. (Bug#8719)
18848 * alloc.c (make_event_array): Use XINT, not XUINT.
18849 There's no need for unsigned here.
18851 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18852 This follows up to the 2011-05-06 change that substituted uintptr_t
18853 for EMACS_INT. This case wasn't caught back then.
18855 Rework Fformat to avoid integer overflow issues.
18856 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18857 now (part of C89). Include <verify.h>.
18858 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18859 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18860 (Fformat): Avoid the prepass trying to compute sizes; it was only
18861 approximate and thus did not catch overflow reliably. Instead, walk
18862 through the format just once, formatting and computing sizes as we go,
18863 checking for integer overflow at every step, and allocating a larger
18864 buffer as needed. Keep track separately whether the format is
18865 multibyte. Keep only the most-recently calculated precision, rather
18866 than them all. Record whether each argument has been converted to
18867 string. Use EMACS_INT, not int, for byte and char and arg counts.
18868 Support field widths and precisions larger than INT_MAX. Avoid
18869 sprintf's undefined behavior with conversion specifications such as %#d
18870 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18871 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18872 formatting out-of-range floating point numbers with int
18873 formats. (Bug#8668)
18875 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18877 * data.c: Avoid integer truncation in expressions involving floats.
18878 * data.c: Include <intprops.h>.
18879 (arith_driver): When there's an integer overflow in an expression
18880 involving floating point, convert the integers to floating point
18881 so that the resulting value does not suffer from catastrophic
18882 integer truncation. For example, on a 64-bit host (* 4
18883 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18884 Do not rely on undefined behavior after integer overflow.
18886 merge count_size_as_multibyte, parse_str_to_multibyte
18887 * character.c, character.h (count_size_as_multibyte):
18888 Rename from parse_str_to_multibyte; all uses changed.
18889 Check for integer overflow.
18890 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18891 since it's now a duplicate of the other. This is more of
18892 a character than a buffer op, so better that it's in character.c.
18893 * fns.c, print.c: Adjust to above changes.
18895 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18897 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18899 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18901 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18902 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18903 (x_clipboard_manager_save): Now static.
18904 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18906 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18907 (crypto_hash_function): Now static.
18908 Fix pointer signedness problems. Avoid unnecessary initializations.
18910 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18912 * termhooks.h (Vselection_alist): Make it terminal-local.
18914 * terminal.c (create_terminal): Initialize it.
18916 * xselect.c: Support for clipboard managers.
18917 (Vselection_alist): Move to termhooks.h as terminal-local var.
18918 (LOCAL_SELECTION): New macro.
18919 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18920 (symbol_to_x_atom): Remove gratuitous arg.
18921 (x_handle_selection_request, lisp_data_to_selection_data)
18922 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18923 (x_own_selection, x_get_local_selection, x_convert_selection):
18924 New arg, specifying work frame. Use terminal-local Vselection_alist.
18925 (some_frame_on_display): Delete unused function.
18926 (Fx_own_selection_internal, Fx_get_selection_internal)
18927 (Fx_disown_selection_internal, Fx_selection_owner_p)
18928 (Fx_selection_exists_p): New optional frame arg.
18929 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18930 (x_handle_selection_clear): Don't treat other terminals with the
18931 same keyboard specially. Use the terminal-local Vselection_alist.
18932 (x_clear_frame_selections): Use Frun_hook_with_args.
18934 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18936 * xterm.h: Add support for those atoms.
18938 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18940 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18941 (converted_selections, conversion_fail_tag): New global variables.
18942 (x_selection_request_lisp_error): Free the above.
18943 (x_get_local_selection): Remove unnecessary code.
18944 (x_reply_selection_request): Args changed; handle arbitrary array
18945 of converted selections stored in converted_selections.
18946 Separate the XChangeProperty and SelectionNotify steps.
18947 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18948 (x_convert_selection): New function.
18949 (x_handle_selection_event): Simplify.
18950 (x_get_foreign_selection): Don't ignore incoming requests while
18951 waiting for an answer; this will fail when we implement
18952 SAVE_TARGETS, and seems unnecessary anyway.
18953 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18954 (Vx_sent_selection_functions): Doc fix.
18956 2011-05-26 Leo Liu <sdl.web@gmail.com>
18958 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18960 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18962 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18964 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18965 for fringe update if it has periodic bitmap.
18966 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18967 and fringe_bitmap_periodic_p.
18969 * fringe.c (get_fringe_bitmap_data): New function.
18970 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18971 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18972 row. Mark glyph row for fringe update if periodicity changed.
18974 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18975 for fringe update unless it has periodic bitmap.
18977 2011-05-25 Kenichi Handa <handa@m17n.org>
18979 * xdisp.c (get_next_display_element): Set correct it->face_id for
18980 a static composition.
18982 2011-05-24 Leo Liu <sdl.web@gmail.com>
18985 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18987 * fns.c (crypto_hash_function, Fsha1): New function.
18988 (Fmd5): Use crypto_hash_function.
18989 (syms_of_fns): Add Ssha1.
18991 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18993 * gnutls.c: Remove unused macros.
18994 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18995 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18996 Remove macros that are defined and never used.
18997 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18999 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19001 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19002 (Fx_get_selection_internal): Minor cleanup.
19003 (Fx_own_selection_internal): Rename arguments for consistency with
19006 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19008 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19010 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19012 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19014 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19016 * dispnew.c (scrolling_window): Don't exclude the case that the
19017 last enabled row in the desired matrix touches the bottom boundary.
19019 2011-05-21 Glenn Morris <rgm@gnu.org>
19021 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19022 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19023 and add some more files.
19025 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19027 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19028 report_file_error introduced by the change from 2011-05-07.
19030 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19032 * systime.h (Time): Define only if emacs is defined.
19033 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19034 where the include path doesn't have X11/X.h by default. See
19035 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19037 2011-05-20 Kenichi Handa <handa@m17n.org>
19039 * composite.c (find_automatic_composition): Fix previous change.
19041 2011-05-20 Glenn Morris <rgm@gnu.org>
19043 * lisp.mk: New file, split from Makefile.in.
19044 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19045 (shortlisp): Remove.
19046 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19048 2011-05-19 Glenn Morris <rgm@gnu.org>
19050 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19051 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19052 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19053 (lisp): Set the order to that of loadup.el.
19054 (shortlisp): Make it a copy of $lisp.
19055 (SOME_MACHINE_LISP): Remove.
19056 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19057 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19059 2011-05-18 Kenichi Handa <handa@m17n.org>
19061 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19062 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19063 (find_automatic_composition): Mostly rewrite for efficiency.
19065 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19067 * makefile.w32-in: Update dependencies.
19069 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19071 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19072 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19074 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19076 Fix some integer overflow issues, such as string length overflow.
19078 * insdel.c (count_size_as_multibyte): Check for string overflow.
19080 * character.c (lisp_string_width): Check for string overflow.
19081 Use EMACS_INT, not int, for string indexes and lengths; in
19082 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19083 the resulting string length overflows an EMACS_INT; instead,
19084 report a string overflow if no precision given. When checking for
19085 precision exhaustion, use a check that cannot possibly have
19086 integer overflow. (Bug#8675)
19087 * character.h (lisp_string_width): Adjust to new signature.
19089 * alloc.c (string_overflow): New function.
19090 (Fmake_string): Use it. This doesn't change behavior, but saves
19091 a few bytes and will simplify future changes.
19092 * character.c (string_escape_byte8): Likewise.
19093 * lisp.h (string_overflow): New decl.
19095 Fixups, following up to the user-interface timestamp change.
19096 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19097 for UI timestamps, instead of unsigned long.
19098 * msdos.c (mouse_get_pos): Likewise.
19099 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19100 * w32gui.h (Time): Define by including "systime.h" rather than by
19101 declaring it ourselves. (Bug#8664)
19103 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19104 * image.c (clear_image_cache): Likewise.
19106 * term.c (term_mouse_position): Don't assume time_t wraparound.
19108 Be more systematic about user-interface timestamps.
19109 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19110 and sometimes 'EMACS_UINT', to represent these timestamps.
19111 This change causes it to use 'Time' uniformly, as that's what X uses.
19112 This makes the code easier to follow, and makes it easier to catch
19113 integer overflow bugs such as Bug#8664.
19114 * frame.c (Fmouse_position, Fmouse_pixel_position):
19115 Use Time, not unsigned long, for user-interface timestamps.
19116 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19117 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19118 * keyboard.h (last_event_timestamp): Likewise.
19119 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19120 * menu.h (xmenu_show): Likewise.
19121 * term.c (term_mouse_position): Likewise.
19122 * termhooks.h (struct input_event.timestamp): Likewise.
19123 (struct terminal.mouse_position_hook): Likewise.
19124 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19125 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19126 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19127 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19128 what it was before.
19129 * menu.h, termhooks.h: Include "systime.h", for Time.
19131 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19132 Don't assume that the difference between two unsigned long values
19133 can fit into an integer. At this point, we know button_down_time
19134 <= event->timestamp, so the difference must be nonnegative, so
19135 there's no need to cast the result if double-click-time is
19136 nonnegative, as it should be; check that it's nonnegative, just in
19137 case. This bug is triggered when events are more than 2**31 ms
19138 apart (about 25 days). (Bug#8664)
19140 * xselect.c (last_event_timestamp): Remove duplicate decl.
19141 (x_own_selection): Remove needless cast to unsigned long.
19143 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19144 that always fit in int. Use a sentinel instead of a counter, to
19145 avoid a temp and to allay GCC's concerns about possible int overflow.
19146 * frame.h (struct frame): Use int for menu_bar_items_used
19147 instead of EMACS_INT, since it always fits in int.
19149 * menu.c (grow_menu_items): Check for int overflow.
19151 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19153 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19154 Before, the code was not consistent. These values cannot exceed
19155 2**31 - 1 so there's no need to make them unsigned.
19156 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19157 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19158 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19160 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19162 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19163 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19164 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19165 presumably because the widths might not match.
19167 * window.c (size_window): Avoid needless test at loop start.
19169 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19171 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19173 2011-05-12 Drew Adams <drew.adams@oracle.com>
19175 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19177 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19179 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19180 `width' to `bar_area_x' and `bar_area_width', respectively.
19181 (x_scroll_run): Take account of fringe background extension.
19183 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19184 Rename local vars `left' and `width' to `bar_area_x' and
19185 `bar_area_width', respectively.
19186 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19187 background extension.
19189 2011-05-10 Jim Meyering <meyering@redhat.com>
19191 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19193 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19195 * image.c (Finit_image_library): Return t for built-in image types,
19196 like pbm and xbm. (Bug#8640)
19198 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19200 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19202 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19204 * w32console.c (Fset_screen_color): Doc fix.
19205 (Fget_screen_color): New function.
19206 (syms_of_ntterm): Defsubr it.
19208 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19209 unlink the temporary file if Fcall_process didn't create it in the
19211 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19212 child process will be redirected to a file specified with `:file'.
19213 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19214 cue to call_process_cleanup not to close that handle.
19216 2011-05-07 Ben Key <bkey76@gmail.com>
19218 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19219 one of two shell specific rules, either bootstrap-temacs-CMD or
19220 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19221 to the previous implementation of the bootstrap-temacs rule.
19222 The bootstrap-temacs-CMD rule is similar to the previous
19223 implementation of the bootstrap-temacs rule except that it
19224 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19227 These changes, along with some changes to nt/configure.bat,
19228 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19229 earlier fix to add support for --cflags and --ldflags options
19230 that include quotes so that it works whether make uses cmd or
19233 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19235 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19236 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19238 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19239 a string. Handle both cases.
19240 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19241 (Fdbus_register_method): Use Qinvalid_function.
19243 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19245 * makefile.w32-in: Update dependencies.
19246 (LISP_H): Add inttypes.h and stdin.h.
19247 (PROCESS_H): Add unistd.h.
19249 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19251 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19252 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19254 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19256 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19258 * term.c (vfatal): Remove stray call to va_end.
19259 It's not needed and the C Standard doesn't allow it here anyway.
19261 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19262 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19264 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19267 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19269 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19271 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19273 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19275 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19277 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19278 * charset.c (Fdefine_charset_internal): Don't initialize
19279 charset.code_space[15]. The value was garbage, on hosts with
19280 32-bit int (Bug#8600).
19282 * lread.c (read_integer): Be more consistent with string-to-number.
19283 Use string_to_number to do the actual conversion; this avoids
19284 rounding errors and fixes some other screwups. Without this fix,
19285 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19286 (digit_to_number): Move earlier, for benefit of read_integer.
19287 Return -1 if the digit is out of range for the base, -2 if it is
19288 not a digit in any supported base. (Bug#8602)
19290 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19292 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19293 to match comment at start of function. This also removes a
19294 GCC warning about overflow in a 32+64-bit port.
19296 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19298 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19299 Reported by Stefan Monnier in
19300 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19301 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19302 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19304 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19305 (EMACS_UINTPTR): Likewise, with uintptr_t.
19307 * lisp.h: Prefer 64-bit EMACS_INT if available.
19308 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19309 on 32-bit hosts that have 64-bit int, so that they can access
19311 However, temporarily disable this change unless the temporary
19312 symbol WIDE_EMACS_INT is defined.
19314 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19316 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19317 This removes an assumption that EMACS_INT and long are the same
19318 width as pointers. The assumption is true for Emacs porting targets
19319 now, but we want to make other targets possible.
19320 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19321 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19322 In the rest of the code, change types of integers that hold casted
19323 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19324 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19325 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19326 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19327 No need to cast type when ORing.
19328 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19329 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19330 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19331 assume EMACS_INT is the same width as char *.
19332 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19333 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19334 Remove no-longer-needed casts.
19335 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19336 (xg_tool_bar_help_callback, xg_make_tool_item):
19337 Use EMACS_INTPTR to hold an integer
19338 that will be cast to void *; this can avoid a GCC warning
19339 if EMACS_INT is not the same width as void *.
19340 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19341 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19342 (current_message_1, set_message_1):
19343 Use a local to convert to proper width without a cast.
19344 * xmenu.c (dialog_selection_callback): Likewise.
19346 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19347 Also, don't assume VALBITS / RAND_BITS is less than 5,
19348 and don't rely on undefined behavior when shifting a 1 left into
19350 * lisp.h (get_random): Change signature to match.
19352 * lread.c (hash_string): Use size_t, not int, for hash computation.
19353 Normally we prefer signed values; but hashing is special, because
19354 it's better to use unsigned division on hash table sizes so that
19355 the remainder is nonnegative. Also, size_t is the natural width
19356 for hashing into memory. The previous code used 'int', which doesn't
19357 retain enough info to hash well into very large tables.
19358 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19360 * dbusbind.c: Don't possibly lose pointer info when converting.
19361 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19362 Use XPNTR rather than XHASH, so that the high-order bits of
19363 the pointer aren't lost when converting through void *.
19365 * eval.c (Fautoload): Don't double-shift a pointer.
19367 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19369 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19371 * gnutls.c (DEF_GNUTLS_FN):
19372 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19374 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19376 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19379 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19381 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19382 New version that can reserve upto 2GB of heap space.
19384 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19386 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19388 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19390 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19391 `gnutls_certificate_set_x509_key_file'.
19393 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19395 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19396 Update dependencies.
19398 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19400 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19401 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19402 Remove unused parameter `fildes'.
19403 * process.c (read_process_output, send_process): Don't pass it.
19405 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19407 Fix previous change: the library cache is defined in w32.c.
19408 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19409 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19411 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19413 Implement dynamic loading of GnuTLS on Windows.
19415 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19416 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19417 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19420 * gnutls.c (Qgnutls_dll): Define.
19421 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19422 (gnutls_*): Declare function pointers.
19423 (init_gnutls_functions): New function to initialize function pointers.
19424 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19425 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19426 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19427 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19428 (emacs_gnutls_write, emacs_gnutls_read)
19429 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19430 (Fgnutls_available_p): New function.
19431 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19432 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19433 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19435 * image.c: Include w32.h.
19436 (Vimage_type_cache): Delete.
19437 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19438 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19439 (w32_delayed_load): Move to w32.c.
19441 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19443 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19444 (w32_delayed_load): Move from image.c. When loading a library, record
19445 its filename in the :loaded-from property of the library id.
19446 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19447 Initialize and staticpro them.
19448 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19450 * process.c: Include lisp.h before w32.h, not after.
19451 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19452 instead of gnutls_record_check_pending.
19454 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19456 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19458 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19459 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19462 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19464 * xterm.c (x_set_frame_alpha): Do not set property on anything
19465 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19467 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19469 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19471 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19473 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19474 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19480 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19481 (Qgnutls_bootprop_callbacks_verify): Make static.
19483 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19485 * callproc.c: Indentation fixup.
19487 * sysdep.c (wait_for_termination_1): Make static.
19488 (wait_for_termination, interruptible_wait_for_termination):
19489 Move after wait_for_termination_1.
19491 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19493 * sysdep.c (interruptible_wait_for_termination): New function
19494 which is like wait_for_termination, but allows keyboard
19497 * callproc.c (Fcall_process): Add (:file "file") as an option for
19499 (Fcall_process_region): Ditto.
19501 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19503 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19504 rather than `XVECTOR (FOO)->size'.
19506 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19507 inttypes.h, as a gnulib replacement is used if it not available in
19510 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19512 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19513 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19514 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19516 * coding.c (coding_alloc_by_realloc): Error out if destination
19517 will grow beyond MOST_POSITIVE_FIXNUM.
19518 (decode_coding_emacs_mule): Abort if there isn't enough place in
19519 charbuf for the composition carryover bytes. Reserve an extra
19520 space for up to 2 characters produced in a loop.
19521 (decode_coding_iso_2022): Abort if there isn't enough place in
19522 charbuf for the composition carryover bytes.
19524 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19526 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19527 aborting when %lld or %lll format is passed.
19528 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19529 %llo or %llx format is passed. (Bug#8545)
19531 * window.c (window_scroll_line_based): Use a marker instead of
19532 simple variables to record original value of point. (Bug#7952)
19534 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19535 produced by %s or %c overflows available buffer space. (Bug#8545)
19537 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19539 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19540 (SIZE_MAX): Move defn after all includes, as they might #define it.
19542 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19544 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19546 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19548 * keyboard.c (Qdelayed_warnings_hook): Define.
19549 (command_loop_1): Run `delayed-warnings-hook'
19550 if Vdelayed_warnings_list is non-nil.
19551 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19552 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19554 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19556 * doprnt.c (doprnt): Don't return value smaller than the buffer
19557 size if the message was truncated. (Bug#8545).
19559 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19561 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19562 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19564 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19566 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19568 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19570 * makefile.w32-in: Update dependencies.
19572 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19574 Improve `doprnt' and its usage. (Bug#8545)
19575 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19576 `format_end'. Remove support for %l as a conversion specifier.
19577 Don't use xrealloc. Improve diagnostics when the %l size modifier
19578 is used. Update the commentary.
19580 * eval.c (verror): Simplify calculation of size_t.
19582 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19585 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19587 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19590 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19592 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19593 This makes this file independent of the recent pseudovector change.
19595 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19597 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19599 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19600 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19601 Remove unused local.
19602 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19604 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19605 GCC 4.6.0 optimizes based on type-based alias analysis.
19606 For example, if b is of type struct buffer * and v of type struct
19607 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19608 != &v->size, and therefore "v->size = 1; b->size = 2; return
19609 v->size;" must therefore return 1. This assumption is incorrect
19610 for Emacs, since it type-puns struct Lisp_Vector * with many other
19611 types. To fix this problem, this patch adds a new type struct
19612 vectorlike_header that documents the constraints on layout of vectors
19613 and pseudovectors, and helps optimizing compilers not get fooled
19614 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19615 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19616 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19618 (XSETPVECTYPE): Rewrite in terms of new macro.
19619 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19620 This is a bit clearer, and further avoids the possibility of
19621 undesirable aliasing.
19622 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19623 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19624 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19625 since Lisp_Subr is a special case (no "next" field).
19626 (ASIZE): Now uses header.size rather than size.
19627 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19628 to avoid the hassle of writing XVECTOR (foo)->header.size.
19629 (struct vectorlike_header): New type.
19630 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19631 object, to help avoid aliasing.
19632 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19633 (SUBRP): Likewise, since Lisp_Subr is a special case.
19634 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19635 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19636 (struct Lisp_Hash_Table): Combine first two members into a single
19637 struct vectorlike_header member. All uses of "size" and "next" members
19638 changed to be "header.size" and "header.next".
19639 * buffer.h (struct buffer): Likewise.
19640 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19641 * frame.h (struct frame): Likewise.
19642 * process.h (struct Lisp_Process): Likewise.
19643 * termhooks.h (struct terminal): Likewise.
19644 * window.c (struct save_window_data, struct saved_window): Likewise.
19645 * window.h (struct window): Likewise.
19646 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19647 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19648 * buffer.c (init_buffer_once): Likewise.
19649 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19651 * process.c (Fformat_network_address): Use local var for size,
19654 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19656 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19657 * data.c (atof): Remove decl; no longer used or needed.
19658 (digit_to_number): Move to lread.c.
19659 (Fstring_to_number): Use new string_to_number function, to be
19660 consistent with how the Lisp reader treats infinities and NaNs.
19661 Do not assume that floating-point numbers represent EMACS_INT
19662 without losing information; this is not true on most 64-bit hosts.
19663 Avoid double-rounding errors, by insisting on integers when
19664 parsing non-base-10 numbers, as the documentation specifies.
19665 * lisp.h (string_to_number): New decl, replacing ...
19666 (isfloat_string): Remove.
19667 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19668 (read1): Do not accept +. and -. as integers; this
19669 appears to have been a coding error. Similarly, do not accept
19670 strings like +-1e0 as floating point numbers. Do not report
19671 overflow for integer overflows unless the base is not 10 which
19672 means we have no simple and reliable way to continue.
19673 Break out the floating-point parsing into a new
19674 function string_to_number, so that Fstring_to_number parses
19675 floating point numbers consistently with the Lisp reader.
19676 (digit_to_number): Move here from data.c. Make it static inline.
19677 (E_CHAR, EXP_INT): Remove, replacing with ...
19678 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19679 (string_to_number): New function, replacing isfloat_string.
19680 This function checks for valid syntax and produces the resulting
19681 Lisp float number too. Rework it so that string-to-number
19682 no longer mishandles examples like "1.0e+". Use strtoumax,
19683 so that overflow for non-base-10 numbers is reported only when
19684 there's no portable and simple way to convert to floating point.
19686 * textprop.c (set_text_properties_1): Rewrite for clarity,
19687 and to avoid GCC warning about integer overflow.
19689 * intervals.h (struct interval): Use EMACS_INT for members
19690 where EMACS_UINT might cause problems. See
19691 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19692 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19693 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19695 (offset_intervals): Tell GCC not to worry about length overflow
19696 when negating a negative length.
19698 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19699 (overrun_check_free): Likewise.
19701 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19702 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19705 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19706 (gnutls_make_error): Rename local to avoid shadowing.
19707 (gnutls_emacs_global_deinit): ifdef out; not used.
19708 (Fgnutls_boot): Use const for pointer to readonly storage.
19709 Comment out unused local. Fix pointer signedness problems.
19711 * lread.c (openp): Don't stuff size_t into an 'int'.
19712 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19713 about possible signed overflow.
19715 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19716 (GDK_KEY_g): Don't define if already defined.
19717 (xg_prepare_tooltip): Avoid pointer signedness problem.
19718 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19720 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19721 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19723 * xfns.c (Fx_window_property): Simplify a bit,
19724 to make a bit faster and to avoid GCC 4.6.0 warning.
19725 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19727 * fns.c (internal_equal): Don't assume size_t fits in int.
19729 * alloc.c (compact_small_strings): Tighten assertion a little.
19731 Replace pEd with more-general pI, and fix some printf arg casts.
19732 * lisp.h (pI): New macro, generalizing old pEd macro to other
19733 conversion specifiers. For example, use "...%"pI"d..." rather
19734 than "...%"pEd"...".
19735 (pEd): Remove. All uses replaced with similar uses of pI.
19736 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19737 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19738 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19739 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19740 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19741 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19742 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19744 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19745 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19746 * print.c (safe_debug_print, print_object): Likewise.
19747 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19749 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19750 avoiding the 0 flag, which is not portable.
19751 * process.c (Fmake_network_process): Use pI to avoid cast.
19752 * region-cache.c (pp_cache): Likewise.
19753 * xdisp.c (decode_mode_spec): Likewise.
19754 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19755 behavior on 64-bit hosts with printf arg.
19756 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19757 (x_stop_queuing_selection_requests): Likewise.
19758 (x_get_window_property): Don't truncate byte count to an 'int'
19761 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19762 here, since it parses constructs like leading '-' and spaces,
19763 which are not wanted; and it overflows with large numbers.
19764 Instead, simply match F[0-9]+, which is what is wanted anyway.
19766 * alloc.c: Remove unportable assumptions about struct layout.
19767 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19768 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19769 (allocate_vectorlike, make_pure_vector): Use the new macros,
19770 plus offsetof, to remove unportable assumptions about struct layout.
19771 These assumptions hold on all porting targets that I know of, but
19772 they are not guaranteed, they're easy to remove, and removing them
19773 makes further changes easier.
19775 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19776 This doesn't fix a bug but makes the code clearer.
19777 (string_overrun_cookie): Now const. Use initializers that
19778 don't formally overflow signed char, to avoid warnings.
19779 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19780 can cause Emacs to crash when string overrun checking is enabled.
19781 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19782 multiple of sizeof (EMACS_INT); it need not be, if
19783 alignof(EMACS_INT) < sizeof (EMACS_INT).
19784 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19786 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19790 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19792 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19793 supposed to be handshaking. (Bug#8556)
19794 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19796 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

19801 (handle_user_signal): Break into debugger when debug-on-event
19802 matches the current signal symbol.
19804 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19806 * alloc.c (check_sblock, check_string_bytes)
19807 (check_string_free_list): Convert to standard C.
19809 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19811 * w32.c (emacs_gnutls_push): Fix typo.
19813 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19815 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19816 "cast to pointer from integer of different size".
19818 Improve doprnt and its use in verror. (Bug#8545)
19819 * doprnt.c (doprnt): Document the set of format control sequences
19820 supported by the function. Use SAFE_ALLOCA instead of always
19823 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19824 is one byte too soon. Don't use xrealloc; instead xfree and
19827 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19829 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19832 * gnutls.c: Renamed global_initialized to
19833 gnutls_global_initialized. Added internals for the
19834 :verify-hostname-error, :verify-error, and :verify-flags
19835 parameters of `gnutls-boot' and documented those parameters in the
19836 docstring. Start callback support.
19837 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19838 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19839 on error. Return error code.
19840 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19841 (emacs_gnutls_read): Likewise.
19842 (Fgnutls_boot): Return handshake error code.

19906 <char-direction-table>: Deleted.
19908 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19910 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19911 * doprnt.c: Include limits.h.
19912 (SIZE_MAX): New macro.
19913 (doprnt): Return a size_t value. 2nd arg is now size_t.
19914 Many local variables are now size_t instead of int or unsigned.
19915 Improve overflow protection. Support `l' modifier for integer
19916 conversions. Support %l conversion. Don't assume an EMACS_INT
19917 argument for integer conversions and for %c.
19919 * lisp.h (doprnt): Restore prototype.
19921 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19922 $(SRC)/character.h.
19924 * Makefile.in (base_obj): Add back doprnt.o.
19926 * deps.mk (doprnt.o): Add back prerequisites.
19927 (callint.o): Depend on character.h.
19929 * eval.c (internal_lisp_condition_case): Include the handler
19930 representation in the error message.
19931 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19932 when breaking from the loop.
19934 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19936 * callint.c (Fcall_interactively): When displaying error message
19937 about invalid control letter, pass the character's codepoint, not
19938 a pointer to its multibyte form. Improve display of the character
19939 in octal and display also its hex code.
19941 * character.c (char_string): Use %x to display the (unsigned)
19942 codepoint of an invalid character, to avoid displaying a bogus
19945 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19946 `error', not SYMBOL_NAME itself.
19948 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19949 character arguments to `error'.
19951 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19952 to `error' in error message about FINAL_CHAR argument. Make sure
19953 FINAL_CHAR is a character, and use %c when it is passed as
19954 argument to `error'.
19956 2011-04-23 Eli Zaretskii <eliz@gnu.org>

20144 ns_descriptor_to_entity that were caused by using free to
20145 deallocate memory blocks that were allocated by xmalloc (via
20146 xstrdup). This caused Emacs to crash when compiled with
20147 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

20166 (emacs_read, emacs_write): Use it.
20167 * process.c (send_process): Adjust to the new signatures of
20168 emacs_write and emacs_gnutls_write. Do not attempt to store

20498 * lisp.h: Remove these decls.
20500 * buffer.c (buffer_count): Remove unused var.
20502 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20503 so that it's not optimized away.
20504 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20505 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20506 exported only to the debugger.
20508 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20509 * atimer.h (run_all_atimers): Remove; not exported.
20511 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20512 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20513 was inaccessible from Lisp.
20514 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20515 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20517 alloc.c: Import and export fewer symbols, and remove unused items.
20518 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20520 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20521 it's not optimized away by whole-program optimization.
20522 (message_enable_multibyte, free_misc): Remove.
20523 (catchlist, handlerlist, mark_backtrace):
20524 Declare only if BYTE_MARK_STACK.

20533 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20534 (mark_backtrace): Define only if BYTE_MARK_STACK.
20535 * xdisp.c (message_enable_multibyte): Now static.
20537 Declare Lisp_Object Q* variables to be 'static' if not exported.
20538 This makes it easier for human readers (and static analyzers)
20539 to see whether these variables are used from other modules.
20540 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20541 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20542 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

20550 Remove decls of unexported vars.
20551 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20553 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20555 Make Emacs functions such as Fatom 'static' by default.
20556 This makes it easier for human readers (and static analyzers)
20557 to see whether these functions can be called from other modules.
20558 DEFUN now defines a static function. To make the function external
20559 so that it can be used in other C modules, use the new macro DEFUE.
20560 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20561 (Finit_image_library):
20562 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20563 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20564 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20565 Remove decls, since these functions are now static.
20566 (Funintern, Fget_internal_run_time): New decls, since these functions
20567 were already external.
20569 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20577 Mark functions with DEFUE instead of DEFUN,
20578 if they are used in other modules.
20579 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20580 decls for now-static functions.
20581 * buffer.h (Fdelete_overlay): Remove decl.

20594 (Fremove_list_of_text_properties): Remove decls.
20595 * keyboard.c (Fthis_command_keys): Remove decl.
20596 (Fcommand_execute): New forward static decl.

20617 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20619 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20620 when at ZV. (Bug#8487)
20622 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20624 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20628 * termcap.c (tgetent): Likewise.
20629 * xfns.c (x_default_font_parameter): Likewise.
20630 * xsettings.c (read_and_apply_settings): Likewise.
20632 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20633 (overrun_check_free): Protoize.
20635 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20637 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20638 since callers should never pass a negative size.
20639 Change the signature to match that of plain 'read' and 'write'; see
20640 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20641 * lisp.h: Update prototypes of emacs_write and emacs_read.
20643 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20645 * xdisp.c (redisplay_window): Don't try to determine the character
20646 position of the scroll margin if the window start point w->startp
20647 is outside the buffer's accessible region. (Bug#8468)
20649 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20651 Fix write-region and its subroutines for buffers > 2GB.
20652 * fileio.c (a_write, e_write): Modify declaration of arguments and
20653 local variables to support buffers larger than 2GB.
20654 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20656 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20657 argument, local variables, and return value.
20659 * lisp.h: Update prototypes of emacs_write and emacs_read.
20661 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20663 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20665 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20667 Fix more problems found by GCC 4.6.0's static checks.
20669 * xdisp.c (vmessage): Use a better test for character truncation.
20671 * charset.c (load_charset_map): <, not <=, for optimization,
20672 and to avoid potential problems with integer overflow.
20673 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20674 * casetab.c (set_identity, shuffle): Likewise.
20675 * editfns.c (Fformat): Likewise.
20676 * syntax.c (skip_chars): Likewise.
20678 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20679 This also lets GCC 4.6.0 generate slightly better loop code.
20681 * callint.c (Fcall_interactively): <, not <=, for optimization.
20682 (Fcall_interactively): Count the number of arguments produced,
20683 not the number of arguments given. This is simpler and lets GCC
20684 4.6.0 generate slightly better code.
20686 * ftfont.c: Distingish more carefully between FcChar8 and char.
20687 The previous code passed unsigned char * to a functions like
20688 strlen and xstrcasecmp that expect char *, which does not
20689 conform to the C standard.
20690 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20691 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20692 char * when the C standard requires it.
20694 * keyboard.c (read_char): Remove unused var.
20696 * eval.c: Port to Windows vsnprintf (Bug#8435).
20697 Include <limits.h>.
20698 (SIZE_MAX): Define if the headers do not.
20699 (verror): Do not give up if vsnprintf returns a negative count.
20700 Instead, grow the buffer. This ports to Windows vsnprintf, which
20701 does not conform to C99. Problem reported by Eli Zaretskii.
20702 Also, simplify the allocation scheme, by avoiding the need for
20703 calling realloc, and removing the ALLOCATED variable.
20705 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20707 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20708 But keep the doprint source code for now, as we might revamp it
20709 and use it again (Bug#8435).
20710 * lisp.h (doprnt): Remove.
20711 * Makefile.in (base_obj): Remove doprnt.o.
20712 * deps.mk (doprnt.o): Remove.
20714 error: Print 32- and 64-bit integers portably (Bug#8435).
20715 Without this change, on typical 64-bit hosts error ("...%d...", N)
20716 was used to print both 32- and 64-bit integers N, which relied on
20717 undefined behavior.
20718 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20719 * lisp.h (error, verror): Mark as printf-like functions.
20720 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20721 Report overflow in size calculations when allocating printf buffer.
20722 Do not truncate output string at its first null byte.
20723 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20724 Truncate the output at a character boundary, since vsnprintf does not
20726 * charset.c (check_iso_charset_parameter): Convert internal
20727 character to string before calling 'error', since %c now has the
20729 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20730 overflow when computing char to be passed to 'error'. Do not
20731 pass Lisp_Object to 'error'; pass the integer instead.
20732 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20733 formatted with plain %d.
20735 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20737 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20739 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20741 * xterm.c (x_catch_errors): Remove duplicate declaration.
20743 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20745 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20747 2011-04-10 Jim Meyering <meyering@redhat.com>
20749 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20750 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20751 return ssize_t not "int", and use size_t as the buffer length.
20752 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20753 * gnutls.h: Update declarations.
20754 * process.c (read_process_output): Use ssize_t, to match.
20755 (send_process): Likewise.
20757 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20759 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20761 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20763 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20764 Use unsigned char, to match FcChar8 type definition.
20766 * xterm.c (handle_one_xevent):
20767 * xmenu.c (create_and_show_popup_menu):
20768 * xselect.c (x_decline_selection_request)
20769 (x_reply_selection_request): Avoid type-punned deref of X events.
20771 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20773 Fix some uses of `int' instead of EMACS_INT.
20774 * search.c (string_match_1, fast_string_match)
20775 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20776 (scan_buffer, find_next_newline_no_quit)
20777 (find_before_next_newline, search_command, Freplace_match)
20778 (Fmatch_data): Make some `int' variables be EMACS_INT.
20780 * xdisp.c (display_count_lines): 3rd argument and return value now
20781 EMACS_INT. All callers changed.
20782 (pint2hrstr): Last argument is now EMACS_INT.
20784 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20785 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20786 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20797 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20798 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20800 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20801 (encode_invocation_designation): Last argument P_NCHARS is now
20803 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20804 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20806 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20809 * ccl.c (Fccl_execute_on_string): Declare some variables
20812 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20814 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20816 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20818 * process.c (Fformat_network_address): Doc fix.
20820 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20822 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20824 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20826 * keyboard.c (read_char): Call Lisp function help-form-show,
20827 instead of using internal_with_output_to_temp_buffer.
20828 (Qhelp_form_show): New var.
20829 (syms_of_keyboard): Use DEFSYM macro.
20831 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20842 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20844 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20846 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>

20863 printf-like functions.
20864 (tiff_load): Add casts to remove these marks before passing them
20865 to system-supplied API.
20867 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20869 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20870 This avoids several warnings with gcc -Wstrict-overflow.
20871 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20872 directly, rather than having caller test rule sign. This avoids
20873 some unnecessary tests.
20874 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20875 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20876 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20878 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20879 (xfont_open): Avoid unnecessary tests.
20881 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20883 * composite.h, composite.c (composition_gstring_put_cache):
20884 Use EMACS_INT, not int, for length.
20886 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20887 breaking out part of COMPOSITION_DECODE_RULE.
20888 (COMPOSITION_DECODE_RULE): Use it.
20889 * composite.c (get_composition_id): Remove unused local vars,
20890 by using the new macro.
20892 * textprop.c (set_text_properties_1): Change while to do-while,
20893 since the condition is always true at first.
20895 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20896 (interval_deletion_adjustment): Return unsigned value.
20899 * process.c (list_processes_1, create_pty, read_process_output):
20900 (exec_sentinel): Remove vars that were set but not used.
20901 (create_pty): Remove unnecessary "volatile"s.
20902 (Fnetwork_interface_info): Avoid possibility of int overflow.
20903 (read_process_output): Do adaptive read buffering even if carryover.
20904 (read_process_output): Simplify nbytes computation if buffered.

20912 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20913 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20915 * print.c (print_error_message): Avoid int overflow.
20917 * font.c (font_list_entities): Redo for clarity,
20918 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20920 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20921 (font_score): Avoid potential overflow in diff calculation.

20924 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20926 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20928 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20929 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20930 can always succeed if overflow has undefined behavior.
20932 * search.c (boyer_moore, wordify): Remove vars set but not used.
20933 (wordify): Omit three unnecessary tests.
20935 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20936 All callers changed. This avoids the need for an unused var.

20940 * dired.c (file_name_completion): Remove var that is set but not used.
20942 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20944 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20945 (Finsert_file_contents): Remove unnecessary code checking fd.
20947 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20948 Check for integer overflow on size calculations.
20950 * buffer.c (Fprevious_overlay_change): Remove var that is set
20953 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20954 Remove vars that are set but not used.
20955 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20956 (timer_check_2): Mark vars as initialized.
20958 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20960 * image.c (lookup_image): Remove var that is set but not used.
20961 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20963 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20964 that are set but not used.
20966 * xfns.c (make_invisible_cursor): Don't return garbage
20967 if XCreateBitmapFromData fails (Bug#8410).
20969 * xselect.c (x_get_local_selection, x_handle_property_notify):
20970 Remove vars that are set but not used.
20972 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20973 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20975 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20976 Remove var that is set but not used.
20977 (scroll_bar_windows_size): Now size_t, not int.
20978 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20979 Check for overflow.
20981 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20982 (map_tty_color) [!defined MSDOS]: Likewise.
20984 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20986 * coding.c: Remove vars that are set but not used.
20987 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20988 All callers changed.
20989 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20990 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20991 (decode_coding_charset): Remove vars that are set but not used.
20993 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20994 that is set but not used.
20996 * print.c (print_object): Remove var that is set but not used.
20998 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20999 The gnulib version avoids calling malloc in the usual case,
21000 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21001 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21002 * filelock.c (current_lock_owner): Likewise.
21003 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21004 * sysdep.c: Include allocator.h, careadlinkat.h.
21005 (emacs_no_realloc_allocator): New static constant.
21006 (emacs_readlink): New function.
21007 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21008 ../lib/careadlinkat.h.
21010 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21012 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21013 first non-nil return value).
21015 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21017 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21018 if not defined (Bug#8403).
21020 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21022 * xdisp.c (display_count_lines): Remove parameter `start',
21023 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21024 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21025 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21027 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21028 and thereabouts. All callers changed.
21029 (get_per_char_metric): Remove parameter `f', unused since
21030 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21032 2011-04-02 Jim Meyering <meyering@redhat.com>
21034 do not dereference NULL upon failed strdup
21035 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21036 (ns_get_family): Likewise.
21038 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21040 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21042 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21044 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21047 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21049 Add lexical binding.
21051 * window.c (Ftemp_output_buffer_show): New fun.
21052 (Fsave_window_excursion):
21053 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21055 * lread.c (lisp_file_lexically_bound_p): New function.
21056 (Fload): Bind Qlexical_binding.
21057 (readevalloop): Remove `evalfun' arg.
21058 Bind Qinternal_interpreter_environment.
21059 (Feval_buffer): Bind Qlexical_binding.
21060 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21062 (syms_of_lread): Declare `lexical-binding'.
21064 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21066 * keyboard.c (eval_dyn): New fun.
21067 (menu_item_eval_property): Use it.
21069 * image.c (parse_image_spec): Use Ffunctionp.
21071 * fns.c (concat, mapcar1): Accept byte-code-functions.
21073 * eval.c (Fsetq): Handle lexical vars.
21074 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21075 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21076 (FletX, Flet): Obey lexical binding.
21077 (Fcommandp): Handle closures.
21078 (Feval): New `lexical' arg.
21079 (eval_sub): New function extracted from Feval. Use it almost
21080 everywhere where Feval was used. Look up vars in lexical env.
21082 (Ffunctionp): Move from subr.el.
21083 (Ffuncall): Handle closures.
21084 (apply_lambda): Remove `eval_flags'.
21085 (funcall_lambda): Handle closures and new byte-code-functions.
21086 (Fspecial_variable_p): New function.
21087 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21088 but without exporting it to Lisp.
21090 * doc.c (Fdocumentation, store_function_docstring):
21091 * data.c (Finteractive_form): Handle closures.
21093 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21096 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21098 (exec_byte_code): New function extracted from Fbyte_code to handle new
21099 calling convention for byte-code-functions. Add new byte-codes.
21101 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21103 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21105 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21107 * xdisp.c (redisplay_internal): Fix prototype.
21109 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21111 * xdisp.c (SCROLL_LIMIT): New macro.
21112 (try_scrolling): Use it when setting scroll_limit.
21113 Limit scrolling to 100 screen lines.
21114 (redisplay_window): Even when falling back on "recentering",
21115 position point in the window according to scroll-conservatively,
21116 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21118 (try_scrolling): When point is above the window, allow searching
21119 as far as scroll_max, or one screenful, to compute vertical
21120 distance from PT to the scroll margin position. This prevents
21121 try_scrolling from unnecessarily failing when
21122 scroll-conservatively is set to a value slightly larger than the
21123 window height. Clean up the case of PT below the margin at bottom
21124 of window: scroll_max can no longer be INT_MAX. When aggressive
21125 scrolling is in use, don't let point enter the opposite scroll
21126 margin as result of the scroll.
21127 (syms_of_xdisp) <scroll-conservatively>: Document the
21128 threshold of 100 lines for never-recentering scrolling.
21130 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21132 * dispextern.h (move_it_by_lines):
21133 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

21135 (message_log_check_duplicate): Remove parameters `prev_bol' and
21136 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21137 (redisplay_internal): Remove parameter `preserve_echo_area',
21138 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21140 * indent.c (Fvertical_motion):
21141 * window.c (window_scroll_pixel_based, Frecenter):
21142 Don't pass `need_y_p' to `move_it_by_lines'.
21144 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21146 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21147 steal a few bits to be more compact.
21148 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21149 Remove unneeded casts.
21151 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21153 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21155 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21156 binding" message (bug#7967).
21158 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21160 Fix more problems found by GCC 4.6.0's static checks.
21162 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21163 Remove unused local var.
21165 * editfns.c (Fmessage_box): Remove unused local var.
21167 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21168 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21169 Omit unused local vars.
21170 * window.c (shrink_windows): Omit unused local var.
21171 * menu.c (digest_single_submenu): Omit unused local var.
21172 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21173 Omit unused local var.
21175 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21176 Don't assume string length fits in int.
21177 (keyremap_step, read_key_sequence): Use size_t for sizes.
21178 (read_key_sequence): Don't check last_real_key_start redundantly.
21180 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21181 instead of alloca (Bug#8344).
21183 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21184 (Fbacktrace_frame): Don't assume nframes fits in int.
21186 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21188 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21191 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21193 * cm.c (calccost): Turn while-do into do-while, for clarity.
21195 * keyboard.c (syms_of_keyboard): Use the same style as later
21196 in this function when indexing through an array. This also
21197 works around GCC bug 48267.
21199 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21201 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21203 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21204 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21206 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21207 This avoids undefined behavior on integer overflow, and is a bit
21208 more convenient anyway since it is compared to a size_t variable.
21210 Variadic C functions now count arguments with size_t, not int.
21211 This avoids an unnecessary limitation on 64-bit machines, which
21212 caused (substring ...) to crash on large vectors (Bug#8344).
21213 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21214 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21222 * fns.c (concat): Likewise.
21223 * frame.c (x_set_frame_parameters): Likewise.
21224 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21225 0 if not found, not -1. All callers changed.
21227 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21228 (stack_copy_size): Now size_t, not int.
21229 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21231 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21233 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21234 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21235 All callers changed.
21237 * lisp.h (multibyte_char_to_unibyte):
21238 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21239 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21247 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21249 * keyboard.c (safe_run_hook_funcall): New function.
21250 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21251 don't set the hook to nil, but remove the offending function instead.
21252 (Qcommand_hook_internal): Remove, unused.
21253 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21254 Vcommand_hook_internal.
21256 * eval.c (enum run_hooks_condition): Remove.
21257 (funcall_nil, funcall_not): New functions.
21258 (run_hook_with_args): Call each function through a `funcall' argument.
21259 Remove `cond' argument, now redundant.

21261 (Frun_hook_with_args_until_failure): Adjust accordingly.
21262 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

21272 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21273 All callers changed.
21275 * w32.c (_wsa_errlist): Use braces for struct initializers.
21277 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21278 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21279 All callers changed.

21434 * buffer.c (Fkill_all_local_variables):
21435 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21437 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21438 unconditionally since it does the check itself.
21440 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21442 Fix more problems found by GCC 4.5.2's static checks.
21444 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21445 the first time through the loop, since we know p0 < p1 then.
21446 This also avoids a gcc -Wstrict-overflow warning.
21448 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21449 leading to a memory leak, possible in functions like
21450 load_charset_map_from_file that can allocate an unbounded number
21451 of objects (Bug#8318).
21453 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21454 that could (at least in theory) be that large.
21456 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21457 This is less likely to overflow, and avoids undefined behavior if
21458 overflow does occur. All callers changed. Use strtoul to scan
21459 for the unsigned long integer.
21460 (pint2hrstr): Simplify and tune code slightly.
21461 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21471 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21474 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21476 * process.c (Fmake_network_process): Use socklen_t, not int,
21477 where POSIX says socklen_t is required in portable programs.
21478 This fixes a porting bug on hosts like 64-bit HP-UX, where
21479 socklen_t is wider than int (Bug#8277).
21480 (Fmake_network_process, server_accept_connection):
21481 (wait_reading_process_output, read_process_output):
21484 * process.c: Rename or move locals to avoid shadowing.

21494 Make tparam.h and terminfo.c consistent.
21495 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21496 Include tparam.h instead, since it declares them.
21497 * cm.h (PC): Remove extern decl; tparam.h now does this.
21498 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21499 * terminfo.c: Include tparam.h, to check interfaces.
21500 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21501 (tparam): Adjust signature to match interface in tparam.h;
21502 this removes some undefined behavior. Check that outstring and len
21503 are zero, which they always are with Emacs.
21504 * tparam.h (PC, BC, UP): New extern decls.
21506 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21507 (xftfont_open): Rename locals to avoid shadowing.

21524 (find_automatic_composition, composition_adjust_point): Likewise.
21525 (composition_update_it): Mark var as initialized.
21526 (find_automatic_composition): Mark vars as initialized,
21527 with a FIXME (Bug#8290).

21531 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21532 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21533 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21534 to avoid shadowing.
21536 * textprop.c (property_change_between_p): Remove; unused.
21538 * intervals.c (interval_start_pos): Now static.
21540 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21546 Fix pointer signedness.
21547 (alsa_choose_format): Remove unused local var.
21548 (wav_play): Initialize a variable to 0, to prevent undefined
21549 behavior (Bug#8278).
21551 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21553 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21555 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21556 clobbering (Bug#8298).
21557 * sysdep.c (sys_subshell): Likewise.
21558 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21560 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21561 This should get cleaned up, so that child_setup has the
21562 same signature on all platforms.
21564 * callproc.c (call_process_cleanup): Now static.
21565 (relocate_fd): Rename locals to avoid shadowing.
21567 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21569 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21570 not to be necessary, and produces flickering.
21572 2011-03-20 Glenn Morris <rgm@gnu.org>
21574 * config.in: Remove file.
21576 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21578 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21579 are now in src/globals.h.

21621 Define only if needed.
21623 * unexelf.c (unexec): Name an expression,
21624 to avoid gcc -Wbad-function-cast warning.
21625 Use a different way to cause a compilation error if anyone uses
21626 n rather than nn, a way that does not involve shadowing.
21627 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21629 * deps.mk (unexalpha.o): Remove; unused.
21631 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21702 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
21705 * lisp.h (eassert): Check that the argument compiles, even if
21706 ENABLE_CHECKING is not defined.
21708 * data.c (Findirect_variable): Name an expression, to avoid
21709 gcc -Wbad-function-cast warning.

21752 (RETALLOC_IF): Define only if needed.
21753 (WORDCHAR_P): Likewise. This one is never needed, but is used
21754 only in a comment talking about a compiler bug, so put inside
21755 the #if 0 of that comment.
21756 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21757 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21785 gcpro1, gcpro2, etc.
21786 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21788 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

21793 Rename locals to avoid shadowing.
21795 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

21799 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...

21801 and the new implementation with inline functions needs to have
21802 current_buffer in scope now, rather than later when the macros
21804 (downcase, upcase1): New static inline functions.
21805 (DOWNCASE, UPCASE1): Reimplement using these functions.
21806 This avoids undefined behavior in expressions like

21847 * buffer.c (fix_overlays_before): Mark locals as initialized.
21848 (fix_start_end_in_overlays): Likewise. This function should be
21849 simplified by using pointers-to-pointers, but that's a different

21852 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21853 (report_overlay_modification): Rename locals to avoid shadowing.

21858 to suppress a gcc -Wclobbered warning that does not seem to be right.
21859 (MAXPATHLEN): Define only if needed.
21861 * process.c (serial_open, serial_configure): Move decls from here ...
21862 * systty.h: ... to here, so that they can be checked.
21864 * fns.c (get_random, seed_random): Move extern decls from here ...
21865 * lisp.h: ... to here, so that they can be checked.
21867 * sysdep.c (reset_io): Now static.
21868 (wait_for_termination_signal): Remove; unused.
21870 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21876 (describe_map_tree):
