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. (Bug#13546)
13 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
14 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
15 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
16 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
17 make sure errno is set to an appropriate value. (Bug#13546)
18 (socket_to_fd): Add assertion against indexing fd_info[] with a
19 value that is out of bounds.
20 (sys_accept): If fd is negative, do not set up the child_process
21 structure for reading.
23 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
25 * composite.c (fill_gstring_header): Remove useless prototype.
27 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
28 * print.c (PRINTDECLARE, print_object):
29 * search.c (compile_pattern, fast_looking_at, search_buffer):
30 (simple_search, boyer_moore, Freplace_match):
31 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
32 (get_overlay_arrow_glyph_row, display_mode_element):
33 (decode_mode_spec_coding, message3):
34 * xfaces.c (face_at_string_position): Use bool for booleans.
37 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
39 Fix AIX port (Bug#13650).
40 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
41 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
42 was #undeffed earlier, so it cannot be used as a macro here.
43 Use the constant and not the macro.
45 2013-02-15 Eli Zaretskii <eliz@gnu.org>
47 * w32proc.c (new_child): If no vacant slots are found in
48 child_procs[], make another pass looking for slots whose process
49 has exited or died. (Bug#13546)
51 * w32.c (sys_pipe): When failing due to file descriptors above
52 MAXDESC, set errno to EMFILE.
53 (_sys_read_ahead): Update cp->status when failing to read serial
54 communications input, so that the status doesn't stay at
55 STATUS_READ_IN_PROGRESS. (Bug#13546)
57 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
59 * gtkutil.c (tb_size_cb): New function.
60 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
62 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
64 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
67 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
69 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
71 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
73 * font.c (font_range): Add pos_byte argument. Adjust comment
75 * font.h (font_range): Adjust prototype.
76 * composite.c (autocmp_chars): Pass byte position to font_range.
77 Break long line. Remove useless prototype and format comment.
79 2013-02-13 Glenn Morris <rgm@gnu.org>
81 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
83 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
85 Improve AIX port some more (Bug#13650).
86 With this, it should be as good as it was in 23.3, though it's
87 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
88 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
89 * unexaix.c (start_of_text): Remove.
90 (_data, _text): Declare as char[], not int, as AIX manual suggests.
91 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
92 (orig_load_scnptr, orig_data_scnptr):
93 Now off_t, not long, since they are file offsets.
94 (make_hdr): Use _data, not start_of_data ().
95 This is the key part of the fix.
96 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
97 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
99 * pre-crt0.c (data_start): Initialize to 1.
100 This ports to compilers that optimize the external declaration
101 'int x = 0;' as if it were 'int x;' to shrink the executable.
103 Improve AIX port (Bug#13650).
104 This doesn't fix the bug, but it makes progress: Emacs builds now.
105 * unexaix.c: Include inttypes.h, stdarg.h.
106 (report_error, report_error_1): Mark as _Noreturn.
107 (report_error): Don't report the wrong errno.
108 (report_error_1): Now varargs. All callers changed.
109 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
110 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
111 (write_ptr): Use %p to print address rather than %lx and a cast
112 to unsigned long. Grow buffer a bit, to be safer.
114 2013-02-13 Eli Zaretskii <eliz@gnu.org>
116 * bidi.c (bidi_resolve_neutral): After finding the next
117 non-neutral character, accept NEUTRAL_ON type as well, because
118 directional control characters, such as LRE and RLE, have their
119 type converted to that by bidi_resolve_weak. This avoids aborts
120 when LRE/RLE follows a run of neutrals.
121 (bidi_move_to_visually_next): Assert that return value of
122 bidi_peek_at_next_level is non-negative. Negative values will
125 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
127 Minor getenv-related fixes.
128 * callproc.c (Fcall_process_region) [!DOS_NT]:
129 Avoid unnecessary duplicate call to getenv.
130 * callproc.c (init_callproc):
131 * dispnew.c (init_display):
132 * sysdep.c (sys_subshell):
133 Omit unnecessary cast of getenv or egetenv.
135 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
137 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
140 2013-02-12 Eli Zaretskii <eliz@gnu.org>
142 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
144 (display_line): Set w->region_showing to the value of
145 it->region_beg_charpos, not to -1. This fixes redisplay
146 optimization when cursor is moved up after M->. (Bug#13623)
148 (try_scrolling): Scroll text up more if point is too close to ZV
149 and inside the scroll margin. This makes sure point is moved
150 outside the scroll margin in these cases.
152 * window.h (struct window): region_showing can no longer be
155 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
157 Tune by using memchr and memrchr.
158 * doc.c (Fsnarf_documentation):
159 * fileio.c (Fsubstitute_in_file_name):
160 * search.c (find_newline, scan_newline):
161 * xdisp.c (pos_visible_p, display_count_lines):
162 Use memchr and memrchr rather than scanning byte-by-byte.
163 * search.c (find_newline): Rename from scan_buffer.
164 Omit first arg TARGET, as it's always '\n'. All callers changed.
166 Clean up read_key_sequence a tiny bit more.
167 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
168 (read_key_sequence): Remove unused locals.
170 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
172 Clean up read_key_sequence a bit; reread active keymaps after first event.
173 * keyboard.c (read_char, read_char_x_menu_prompt)
174 (read_char_minibuf_menu_prompt):
175 Replace nmaps+maps with a single `map' arg.
176 (follow_key): Operate on a single map.
177 (active_maps): New function.
178 (test_undefined): Also return true for nil bindings.
179 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
180 a single (composed) keymap. Remember `first_event' to choose the right
181 set of active keymaps. Recompute the set of keymaps after receiving
182 the first event. Remove GOBBLE_FIRST_EVENT.
183 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
184 * keyboard.h (read_char): Update declaration.
185 * lread.c (read_filtered_event): Adjust call to read_char.
187 2013-02-11 Eli Zaretskii <eliz@gnu.org>
189 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
190 Don't use the limitation on backwards movement when lines are truncated
191 in the window. (Bug#13675)
193 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
195 * marker.c (set_marker_internal): If desired position is passed
196 as a marker, avoid call to buf_charpos_to_bytepos.
197 * window.c (Fset_window_point): Omit redundant type checking.
198 (Fset_window_start): Likewise. Format comment.
199 (window_scroll_pixel_based): Use set_marker_restricted_both
200 with character and byte positions obtained from an iterator.
201 (Fset_window_configuration): Use set_marker_restricted_both.
202 * xdisp.c (message_dolog): Likewise.
204 2013-02-10 Eli Zaretskii <eliz@gnu.org>
206 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
207 When text lines are longer than window's screen lines, don't move back
208 too far. This speeds up some redisplay operations. (Bug#13675)
210 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
212 * syntax.c (scan_sexps_forward): Fix byte position calculation
213 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
215 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
217 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
220 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
222 Minor hashing refactoring.
223 * fns.c (SXHASH_REDUCE): Move to lisp.h.
224 (sxhash_float): Return EMACS_UINT, for consistency with the other
226 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
227 non-static inline function and therefore can't use static vars.
228 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
229 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
230 with the other hash functions.
232 2013-02-09 Eli Zaretskii <eliz@gnu.org>
234 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
235 XXXXXX part of the temporary file pattern is not downcased even
236 when w32-downcase-file-names is non-nil. (Bug#13661)
238 * xdisp.c (decode_mode_spec): Remove handling of %t.
240 * msdos.c (careadlinkatcwd): Remove.
242 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
244 * lread.c (skip_dyn_bytes): New function (bug#12598).
245 (read1): Use it. Use getc instead of READCHAR to read bytes.
246 (load_each_byte): Remove. Update users.
248 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
250 * search.c (scan_buffer): Calculate end byte position just once.
251 (scan_newline): Do not recalculate start_byte.
252 (search_command): Use eassert.
253 * syntax.c (struct lisp_parse_state): New member location_byte.
254 (scan_sexps_forward): Record from_byte and avoid redundant
255 character to byte position calculation ...
256 (Fparse_partial_sexp): ... here. Break too long line.
258 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
260 * lisp.h (make_uninit_vector): New function.
261 * alloc.c (Fvector, Fmake_byte_code):
262 * ccl.c (Fregister_ccl_program):
263 * charset.c (Fdefine_charset_internal, define_charset_internal):
264 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
265 * composite.c (syms_of_composite):
266 * font.c (Fquery_font, Ffont_info, syms_of_font):

268 * ftfont.c (ftfont_shape_by_flt):
269 * indent.c (recompute_width_table):
270 * nsselect.m (clean_local_selection_data):
271 * syntax.c (init_syntax_once):
272 * w32unsubscribe.c (uniscribe_shape):
273 * window.c (Fcurrent_window_configuration):
274 * xfaces.c (Fx_family_fonts):
275 * xselect.c (selection_data_to_lisp_data): Use it.
277 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
279 * coding.c (Fdefine_coding_system_internal): Use AREF where
280 argument is known to be a vector.
281 * fns.c (Flocale_info): Likewise for ASET.
282 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
283 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
285 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
287 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
290 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
291 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
292 updateCollectionBehaviour.
294 * nsterm.m (NEW_STYLE_FS): Remove.
295 (ns_last_use_native_fullscreen): New variable.
296 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
297 (x_set_window_size): Do not take title bar and tool bar into account
298 if isFullscreen returns YES.
299 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
300 (check_native_fs): New function.
301 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
302 (ns_term_init): Remove NEW_STYLE_FS.
303 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
304 and tool bar if isFullscreen returns NO.
305 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
306 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
308 (window:willUseFullScreenPresentationOptions:): New method.
309 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
310 Hide toolbar if not enabled (Bug#13444).
311 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
312 Restore tool bar if enabled, hide it otherwise (Bug#13444).
313 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
314 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
315 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
316 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
317 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
318 (syms_of_nsterm): Add ns-use-native-fullscreen.
320 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
322 * fileio.c (Qchoose_write_coding_system): Now static.
324 2013-02-04 Eli Zaretskii <eliz@gnu.org>
326 * xdisp.c (window_buffer_changed): region_showing can be negative,
327 which still means region is being displayed.
328 (redisplay_internal): Resurrect code that forced redisplay of the
329 whole window when showing region and the mark has changed.
330 Record the new mark position to allow redisplay optimizations.
331 (display_line): If it->region_beg_charpos is non-zero, set the
332 window's region_showing member to -1. (Bug#13623) (Bug#13626)
334 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
335 not bitfield of 1 bit.
337 2013-02-03 Daniel Colascione <dancol@dancol.org>
339 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
340 daemon mode works on cygw32 when Emacs is installed and not just
343 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
345 Avoid file time stamp bug on MS-Windows (Bug#13149).
346 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
347 as FAT32 doesn't update time stamps when truncating them.
348 Also, check that a file time stamp is not a multiple of 100 ns;
349 this should catch all instances of the problem on MS-Windows,
350 as its native file system resolution is 100 ns or worse, and
351 checking for a non-multiple of 100 ns should impose only a small
352 overhead on systems with ns resolution.
354 2013-02-02 Eli Zaretskii <eliz@gnu.org>
356 Avoid encoding file names on MS-Windows when they need to be run
357 through dostounix_filename.
358 * w32.c (normalize_filename): Accept an additional argument
359 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
360 downcase it even if w32-downcase-file-names is non-nil.
361 (dostounix_filename): Accept an additional argument MULTIBYTE and
362 pass it to normalize_filename.
363 (emacs_root_dir): Adjust.
365 * msdos.h (dostounix_filename): Adjust prototype.
367 * w32.h (dostounix_filename): Adjust prototype.
369 * msdos.c (dostounix_filename): Accept an additional argument and
371 (init_environment): Adjust callers of dostounix_filename.
373 * fileio.c (Ffile_name_directory, file_name_as_directory)
374 (directory_file_name, Fexpand_file_name)
375 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
377 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
379 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
380 variables, as egetenv is case-insensitive for DOS_NT.
382 * dired.c (file_name_completion): Don't call Fdirectory_file_name
383 with an encoded file name.
385 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
386 Adjust calls to dostounix_filename.
388 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
390 * unexw32.c (unexec): Adjust call to dostounix_filename.
392 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
394 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
397 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
400 * callproc.c (Fcall_process): Make sure program name in PATH and
401 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
402 is passed to exec/spawnve, which fails unless the file-name
405 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
406 even if w32-quote-process-args is nil.
408 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
410 Fix timestamp bug when write-region appends nothing (Bug#13149).
411 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
412 the file's time stamp doesn't change if Emacs happens to write nothing
413 to the file, and on a buggy file system this could cause Emacs to
414 incorrectly infer that the file system doesn't have the bug.
415 Avoid this problem by inhibiting the inference in this case.
417 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
419 * window.h (struct window): Convert base_line_number, base_line_pos
420 and column_number_displayed members from Lisp_Object to ptrdiff_t.
421 Convert region_showing member from Lisp_Object to bitfield.
422 Remove sequence_number member. Adjust comments.
423 * window.c (sequence_number): Remove.
424 (make_window): Initialize column_number_displayed.
425 * print.c (print_object): Follow the printed representation of
426 frames and print window pointer to distinguish between windows.
427 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
428 * xdisp.c (wset_base_line_number, wset_base_line_pos)
429 (wset_column_number_displayed, wset_region_showing): Remove.
430 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
431 (try_scrolling, try_cursor_movement, redisplay_window)
432 (try_window_reusing_current_matrix, try_window_id, display_line)
433 (display_mode_lines, decode_mode_spec): Adjust users.
434 * .gdbinit (pwinx): Do not print sequence_number.
436 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
438 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
439 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
440 * dired.c: Include <fcntl.h>.
441 (open_directory): New function, which uses open and fdopendir
442 rather than opendir. DOS_NT platforms still use opendir, though.
443 (directory_files_internal, file_name_completion): Use it.
444 (file_attributes): New function, with most of the old Ffile_attributes.
445 (directory_files_internal, Ffile_attributes): Use it.
446 (file_attributes, file_name_completion_stat): First arg is now fd,
447 not dir name. All uses changed. Use fstatat rather than lstat +
449 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
450 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
451 (emacs_readlinkat): New function, with much of the old
452 Ffile_symlink_p, but with an fd argument for speed.
453 It uses readlinkat rather than careadlinkatcwd, so that it
454 need not assume the working directory.
455 (Ffile_symlink_p): Use it.
456 * filelock.c (current_lock_owner): Use emacs_readlinkat
457 rather than emacs_readlink.
458 * lisp.h (emacs_readlinkat): New decl.
459 (READLINK_BUFSIZE, emacs_readlink): Remove.
460 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
461 (emacs_norealloc_allocator, emacs_readlink): Remove.
462 This stuff is moved to fileio.c.
463 * w32.c (fstatat, readlinkat): New functions.
464 (careadlinkat): Don't check that fd == AT_FDCWD.
465 (careadlinkatcwd): Remove; no longer needed.
467 2013-01-31 Glenn Morris <rgm@gnu.org>
469 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
470 (Fwrite_region): Update for new choose_write_coding_system args.
471 Move the last piece of choose_write_coding_system here. (Bug#13522)
472 (syms_of_fileio): Add choose-write-coding-system.
474 2013-01-30 Eli Zaretskii <eliz@gnu.org>
476 * w32.c (sys_open): Zero out the flags for the new file descriptor.
477 (sys_close): Zero out the flags for the file descriptor before
478 closing it. (Bug#13546)
480 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
481 (logon_network_drive, stat_worker, symlink, chase_symlinks):
482 Use CharNextExA and CharPrevExA to iterate over file names encoded in
485 * w32.c (w32_get_long_filename, init_environment, readlink):
486 Support file names encoded in DBCS codepages.
487 (readlink): Use the current file-name-coding-system, not the ANSI
488 codepage, to decode and handle targets of symlinks.
490 2013-01-28 Eli Zaretskii <eliz@gnu.org>
492 * w32.c (opendir): Now accepts a 'const char *'.
494 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
496 Remove obsolete redisplay code. See the discussion at
497 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
498 * dispnew.c (preemption_period, preemption_next_check): Remove.
499 (Vredisplay_preemption_period): Likewise.
500 (update_frame, update_single_window, update_window, update_frame_1):
501 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
502 used, following the 2012-06-22 change.
504 2013-01-25 Eli Zaretskii <eliz@gnu.org>
506 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
508 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
510 * font.c (num_fonts): Remove the leftover from old
511 debugging code. Adjust comment style here and there.

516 2013-01-25 Eli Zaretskii <eliz@gnu.org>
518 * w32.c (max_filename_mbslen): New function.
519 (normalize_filename, readdir): Use it to detect locales where ANSI
520 encoding of file names uses a double-byte character set (DBCS).
521 If a DBCS encoding is used, advance by characters using
522 CharNextExA, instead of incrementing a 'char *' pointer.
523 Use _mbslwr instead of _strlwr. (Bug#13515)
525 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
526 request of memory reservation to 1.7GB. (Bug#13065)
528 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
530 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
531 at check_extra_latin label. (Bug#13505)
533 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
535 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
536 Avoid redundant calls to strlen.
538 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
540 Drop async_visible and async_iconified fields of struct frame.
541 This is possible because async input is gone; for details, see
542 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
543 * frame.h (struct frame): Remove async_visible and async_iconified
544 members, convert garbaged to unsigned bitfield. Adjust comments.
545 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
546 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
547 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
548 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
549 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
551 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
552 properly. Likewise for obscured.
554 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
557 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
559 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
561 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
562 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
564 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
566 * xdisp.c (message2, message2_nolog): Remove functions.
567 (message3, message3_nolog): Extract nbytes and multibyteness directly
568 from the string. Change all callers.
569 (message3_nolog): Don't set message_enable_multibyte since set_message
570 will reset it anyway.
571 (message1, message1_nolog): Use message3.
572 (vmessage): Use a stack allocated buffer rather than f->message_buf.
573 (with_echo_area_buffer): Remove last two arguments. Update all callers.
574 (set_message): Drop all but the second arg, which has to be a string.
575 (set_message_1): Simplify now that we know that a1 is NULL and the
576 second arg is a string.
577 * frame.h (struct frame): Remove `message_buf' field.
578 Use glyphs_initialized_p instead.
579 (FRAME_MESSAGE_BUF): Remove macro.
580 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
581 * lisp.h (message2, message2_nolog): Remove declarations.
582 (message3, message3_nolog): Update declarations.
583 * keyboard.c (read_char_minibuf_menu_text)
584 (read_char_minibuf_menu_width): Remove vars.
585 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
586 to correctly handle multibyte strings.
587 * frame.c (delete_frame): Don't free message_buf any more.
588 * editfns.c (message_text, message_length): Remove vars.
589 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
590 * fileio.c (auto_save_error): Use message3 instead of message2.
591 * dispnew.c (adjust_frame_message_buffer): Remove function.
593 2013-01-23 Eli Zaretskii <eliz@gnu.org>
595 * w32term.c (w32fullscreen_hook): Account correctly for the screen
596 real estate used for the tool bar and the menu bar.
598 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
600 * insdel.c (prepare_to_modify_buffer): Force redisplay if
601 hidden buffer is prepared to modification (Bug#13164).
603 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
605 * window.h (struct window): Change window_end_valid member from
606 Lisp_Object to a bitfield. Adjust comments.
607 (wset_window_end_valid): Remove.
608 * window.c (adjust_window_count): Clear window_end_valid.
609 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
610 (Fwindow_line_height, set_window_buffer, Frecenter)
611 (Fsplit_window_internal, Fdelete_other_windows_internal)
612 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
613 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
614 * xdisp.c (check_window_end, reconsider_clip_changes)
615 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
616 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
617 (find_first_unchanged_at_end_row, try_window_id): Likewise.
619 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
621 * xdisp.c (mark_window_display_accurate): Simplify the loop
622 assuming that the only one of vchild, hchild or buffer window
623 slots is non-nil. Call mark_window_display_accurate_1 for
624 the leaf windows only.
625 (mark_window_display_accurate_1): Always assume leaf window.
628 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
630 * emacs.c (Qkill_emacs_hook): Now static.
632 * fileio.c (Finsert_file_contents): Simplify.
633 Remove unnecessary assignments and tests.
635 2013-01-21 Eli Zaretskii <eliz@gnu.org>
637 * w32.c (acl_set_file): Don't test for errors unless
638 set_file_security returns FALSE. Avoids spurious errors when
641 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
643 * fileio.c (Finsert_file_contents): Revert code introduced at
644 2013-01-18 in favor of the simpler and generally better fix.
645 Save stack space by removing 'buffer' and reusing 'read_buf'
648 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
650 * lisp.h (eabs): Define unconditionally (Bug#13419).
651 The old "#if !defined (eabs)" was an unnecessary revenant of back
652 when this macro was called "abs". Document 'eabs' better.
654 2013-01-19 Glenn Morris <rgm@gnu.org>
656 * fns.c (Frandom): Doc fix.
658 2013-01-19 Eli Zaretskii <eliz@gnu.org>
660 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
661 segfault when there are lots of overlays.
663 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
664 when there are lots of overlays.
665 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
666 for the details and a way to reproduce.
668 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
670 * fileio.c: Use O_APPEND to append.
671 This corresponds better to the natural interpretation of "append",
672 and avoids the need to open the output file twice, or to invoke
673 lseek when APPEND is neither nil nor a number.
674 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
675 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
676 file possibly twice, and lseeking to its end; this avoids the
677 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
678 at the same time: the combination is never needed and apparently
679 it doesn't work with DOS_NT.
681 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
682 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
684 Allow floating-point file offsets.
685 Problem reported by Vitalie Spinu in
686 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
687 * fileio.c (emacs_lseek): Remove.
688 (file_offset): New function.
689 (Finsert_file_contents, Fwrite_region): Use it.
691 2013-01-19 Chong Yidong <cyd@gnu.org>
693 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
694 aborting on Fsignal (Bug#13289).
696 2013-01-19 Eli Zaretskii <eliz@gnu.org>
698 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
699 set_file_security as failure due to insufficient privileges.
700 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
701 (fstat): Return owner and group like 'stat' and 'lstat' do.
703 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
705 Work around bug in CIFS and vboxsf file systems (Bug#13149).
706 The bug was observed on Ubuntu operating inside a virtual machine,
707 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
708 The workaround introduces a race condition on non-buggy hosts,
709 but it's an unlikely race and anyway there's a nearly identical
710 nearby race that can't be fixed.
711 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
713 (Fwrite_region): Test for file system time stamp bug.
714 (init_fileio): New function.
715 * lisp.h (init_fileio): Declare it.
716 * emacs.c (main): Call it.
718 * fileio.c (Finsert_file_contents): Simplify new diagnostic
719 and make it more consistent with other stat-failure diagnostics.
721 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
723 Fix crash when inserting data from non-regular files.
724 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
725 for the error description produced by valgrind.
726 * fileio.c (read_non_regular): Rename to read_contents.
727 Free Lisp_Save_Value object used to pass parameters.
728 (read_non_regular_quit): Rename to read_contents_quit.
729 (Finsert_file_contents): Redesign internal file reading loop to adjust
730 gap and end positions after each read and so help make_gap to work
731 properly. Do not signal an I/O error too early and so do not leave
732 not yet decoded characters in a buffer, which was the reason of
733 redisplay crash. Use list2 to build return value. Adjust comments.
735 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
737 Close a race when statting and reading files (Bug#13149).
738 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
739 This avoids a race if the file is renamed between stat and open.
740 This race is not the problem originally noted in Bug#13149;
741 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
743 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
745 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
746 objects, related functions and macros.
747 (make_save_value): Adjust prototype.

750 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
751 * alloc.c (format_save_value): Rename to make_save_value.
752 (make_save_pointer): New function.
753 (record_xmalloc): Use make_save_pointer.
754 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
755 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
756 Change users of make_save_value to make_save_pointer.
757 Likewise for format_save_value and make_save_value.
759 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
761 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
762 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.

766 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
768 * alloc.c (free_save_value): Now static.
770 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
772 * keymap.c (map_keymap_internal): Use format_save_value.
773 (map_keymap_char_table_item): Adjust accordingly.
774 * fileio.c (non_regular_fd, non_regular_inserted)
775 (non_regular_nbytes): Remove.
776 (Finsert_file_contents): Convert trytry to ptrdiff_t.
777 Use format_save_value to pass parameters to read_non_regular.
778 (read_non_regular): Use XSAVE_ macros to extract parameters.
780 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
782 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
784 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
786 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
787 extraction from any Lisp_Save_Value slot. Add type checking.
788 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
789 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
790 * xselect.c: All users changed.
792 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
794 Some convenient bits to deal with Lisp_Save_Values.
795 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
796 (allocate_misc): Remove prototype.
797 (format_save_value): New prototype.

802 * editfns.c (save_excursion_save): Use format_save_value.
803 (save_excursion_restore): Use XSAVE_OBJECT.
805 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
807 Avoid needless casts with XSAVE_POINTER.
808 * alloc.c (mark_object) [GC_MARK_STACK]:
809 * dired.c (directory_files_internal_unwind):
810 * fileio.c (do_auto_save_unwind):
811 * gtkutil.c (pop_down_dialog):
812 * keymap.c (map_keymap_char_table_item):
813 * lread.c (load_unwind):
814 * nsmenu.m (pop_down_menu):
815 * print.c (print_object) [GC_MARK_STACK]:
816 * xfns.c (clean_up_file_dialog):
817 * xmenu.c (cleanup_widget_value_tree):
818 Omit casts between XSAVE_POINTER and a pointer type.
820 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
822 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
823 * eval.c (eval_sub): Protect `form' from being GCed before its
824 car and cdr becomes protected with the backtrace entry.
826 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
828 Make Lisp_Save_Value more versatile storage for up to four objects.
829 * lisp.h (toplevel): Enumeration to describe types of saved objects.
830 (struct Lisp_Save_Value): New layout. Adjust comments.
831 (XSAVE_POINTER): New macro.
832 (XSAVE_INTEGER): Likewise.
833 (allocate_misc): Add prototype.
834 (free_misc): Likewise.
835 * alloc.c (allocate_misc): Now global.
836 (free_misc): Likewise. Adjust comment.
837 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
838 (free_save_value): Likewise.
839 (mark_object): Likewise.
840 * editfns.c (save_excursion_save): Pack everything within
841 Lisp_Save_Value and so avoid xmalloc.
842 (save_excursion_restore): Adjust to match new layout. Use free_misc
843 because we do not allocate extra memory any more. Add eassert.
844 * print.c (print_object): New code to print Lisp_Save_Value. Do not
845 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
846 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
847 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
848 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
850 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>
852 * nsfont.m (LCD_SMOOTHING_MARGIN): New define.
853 (nsfont_draw): Remove disabling of LCD smoothing.

857 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
859 Fix SIGDANGER handlers, for AIX (Bug#13408).
860 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
861 Move handlers here from emacs.c; they were out of place.
863 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
865 * xterm.c (syms_of_xterm): Adjust documentation for
866 scroll-bar-adjust-thumb-portion.
868 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
870 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
871 determine whether scroll bar thumb size should be adjusted or
872 not. Use variable for MOTIF.
874 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
877 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

886 (nsfont_open): Move block_input earlier. Add unblock_input before early
888 (nsfont_draw): Add block/unblock_input calls.
890 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
892 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
893 for old_charpos and old_bytepos.
895 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
897 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
898 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
899 Clear tzvalbuf_in_environ if this workaround is in effect.
900 Problem and fix reported by Kazuhiro Ito.
902 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
904 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):
905 Fix ambiguous doc string cross-reference(s).
907 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
908 doc string cross-reference(s).
910 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
911 string cross-reference(s).
913 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
915 Avoid unnecessary byte position calculation for the gap movement.
916 Since all users of move_gap do CHAR_TO_BYTE for other purposes
917 anyway, all of them should use move_gap_both instead.
918 * lisp.h (move_gap): Remove prototype.
919 * insdel.c (move_gap): Remove.
920 (move_gap_both): Add eassert.
921 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
922 * xml.c (parse_region): Likewise.
924 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
926 emacsclient -t should not suspend Emacs server (Bug#13387)
927 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
929 * term.c (init_tty): Use them instead of rolling our own code.
930 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
931 switches from 'signal' to 'pthread_sigmask', which is safer in
932 multithreaded applications.
933 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
934 which has already arranged for that.
935 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
936 This is the main part of the bug fix.
938 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
940 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around
941 x_last_font_name (Bug#13403).
943 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
945 Omit buffer_slot_type_mismatch and use generic predicates to enforce
946 the type of per-buffer values where appropriate.
947 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to

1017 * nsterm.m (ns_draw_underwave):
1018 * w32term.c (w32_draw_underwave):
1019 * xterm.c (x_draw_underwave): Make underwave look more triangular
1020 and also degrade gracefully for small fonts. (Bug#13000)
1022 * nsterm.m (ns_draw_text_decoration):
1023 * w32term.c (x_draw_glyph_string):
1024 * xterm.c (x_draw_glyph_string): Don't use previous underline
1025 thickness and position if previous underline type is underwave.

1045 * term.c (tty_ins_del_lines):
1046 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):

1049 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1051 * w32.c (unsetenv): Set up the string passed to _putenv
1053 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1054 for the bug this caused.

1058 * coding.c (Qmac): Now static.
1060 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>

1080 (xg_update_submenu): Skip tearoff only if
1081 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1082 (xg_initialize): Initialize xg_detached_menus only if
1083 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1085 * xterm.h (struct x_output): Surround handlebox_widget with
1086 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

1112 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1114 Port EXTERNALLY_VISIBLE to Clang 3.2.
1115 * conf_post.h (__has_attribute): New macro.
1116 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1118 2012-12-27 Glenn Morris <rgm@gnu.org>
1120 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1121 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1123 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1125 * fileio.c (file_name_as_directory, directory_file_name):
1126 Accept an additional argument MULTIBYTE to indicate whether the input C
1127 came from a multibyte or a unibyte Lisp string; all callers
1128 adjusted. Don't assume the input string is always multibyte.
1130 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1131 don't ENCODE_FILE them, and return a unibyte string if the input
1133 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1134 don't assume the input strings will always be multibyte. If the
1135 input strings are multibyte, decode strings obtained from C
1138 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1140 * lisp.h (toplevel): Add two notices to the comment about
1141 defining a new Lisp data type.

1149 * keyboard.c (record_asynch_buffer_change): Initialize an event
1150 only if it's really needed.
1151 * frame.h (enum output_method): Remove output_mac member since
1152 it's a leftover from the deleted code.
1153 * frame.c (Fframep): Adjust user here ...
1154 * terminal.c (Fterminal_live_p): ... and here.
1155 * coding.c (Qmac): Now here because it's only used to denote
1156 end-of-line encoding type.
1157 (syms_of_coding): DEFSYM it.
1158 * frame.h (Qmac): Remove duplicated declaration.
1160 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1162 * window.c (select_window_1): Now static, since it's used only here.

1166 * window.c (window_body_cols): Subtract display margins from the
1167 window body width on TTYs as well. See
1168 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1169 for the original report.
1171 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1173 * xdisp.c (redisplay_window): Remove inner local variable
1174 because the outer shadowed one has the same meaning.
1175 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1177 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1178 (xg_create_tool_bar): Adjust users.
1180 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1182 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1183 * buffer.c (Fget_buffer_create): Use it to set compact field of
1184 struct buffer_text to avoid accessing an uninitialized value
1185 when compact_buffer is called for the first time.
1186 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1187 (Fset_buffer_modified_p): Use buffer_window_count to check
1188 whether the buffer is displayed in some window.
1189 * xdisp.c (message_dolog): Likewise.
1191 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1193 * w32.c (acl_set_file): If setting the file security descriptor
1194 fails, and the new DACL is identical to the existing one, silently
1195 return success. This fixes problems for users backing up their
1196 own files without having the necessary privileges for setting
1197 security descriptors.
1199 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1201 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1202 after WaitForSingleObject returns normally. This expedites reader
1203 thread shutdown when delete_child triggers it.
1204 (reap_subprocess): More accurate commentary for why we call
1205 delete_child only when cp->fd is negative.
1207 * w32.c (sys_close): Do not call delete_child on a subprocess
1208 whose handle is not yet closed. Instead, set its file descriptor
1209 to a negative value, so that reap_subprocess will call
1210 delete_child on that subprocess when its SIGCHLD arrives.
1211 This avoids closing handles used for communications between sys_select
1212 and reader_thread, which doesn't give sys_select a chance to
1213 notice that the process exited and invoke the SIGCHLD handler for
1216 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1218 * nsfns.m (Fns_do_applescript): Run event loop until script has
1219 been executed (Bug#12969).

1227 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1229 * w32term.c (w32fullscreen_hook): New function.
1230 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1232 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1234 * fileio.c (Finsert_file_contents): Doc fix.
1236 * w32proc.c (new_child, delete_child, find_child_pid): For a
1237 subprocess, consider its slot being in use as long as its process
1238 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1239 slot when a new process is started immediately after killing
1240 another one, without waiting enough time for the first process to
1241 be reaped and resources allocated for it be orderly freed.
1243 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1245 2012-12-21 Chong Yidong <cyd@gnu.org>
1247 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1249 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1251 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1253 * w32.c (get_name_and_id): Always pass NULL as the first argument
1254 of lookup_account_sid. Avoids crashes with UNC file names that
1255 refer to DFS domains, not to specific machine names. (Bug#12621)
1256 Remove now unused argument FNAME; all callers changed.
1257 (get_file_owner_and_group): Remove now unused argument FNAME; all
1260 2012-12-21 Chong Yidong <cyd@gnu.org>
1262 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1263 error for invalid chars, don't check for a nil return value.
1265 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1267 Avoid calls to CHAR_TO_BYTE if byte position is known.
1268 * editfns.c (make_buffer_string_both): Use move_gap_both.
1269 (Fbuffer_string): Use make_buffer_string_both.

1273 (charpos_to_bytepos): Remove.
1274 * fileio.c (Finsert_file_contents): Use move_gap_both.
1275 * search.c (Freplace_match): Likewise.

1277 names for byte positions.
1278 * lisp.h (charpos_to_bytepos): Remove prototype.
1279 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1280 * insdel.c (move_gap): Likewise.

1288 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1289 (redisplay_internal): Don't bother selecting the frame to get the
1290 proper value of frame-local variables (bug#13225).
1292 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1294 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1295 Rename 4th argument since it may be buffer or string. Adjust comment.
1296 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1298 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1300 * coding.c (Fdetect_coding_region): Do not check start and end with
1301 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1302 (code_convert_region): Likewise.
1304 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1306 * w32.c (acl_get_file, acl_set_file): Run the file name through
1307 map_w32_filename, and resolve any symlinks in the file name, like
1309 (acl_set_file): Call revert_to_self, if any privileges were

1315 ($(BLD)/w32.$(O)): Update dependencies.
1317 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1319 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1320 propagate redisplay's scrolling (if any) to the right window.
1321 (redisplay_internal): Use ensure_selected_frame.
1322 (display_mode_lines): Complete last fix.
1323 * window.c (select_window_1): New func, extracted from select_window.
1324 (select_window): Use it.

1351 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1353 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1354 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1355 for some of that bug's symptoms can now cause Emacs to abort.
1356 Remove the workaround.
1357 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1358 The bug that caused SIGCHLD to get lost has been fixed, and the
1359 workaround for it can now cause Emacs to abort.
1361 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1363 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1364 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1365 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1432 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1434 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1435 try to get accurate owner and group information from NT file
1436 security APIs. This is to make most callers of 'stat' and
1437 'lstat', which don't need that information, much faster.
1439 * dired.c (Ffile_attributes) [WINDOWSNT]:
1440 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1441 owner and group information from 'lstat'.
1443 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1445 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1446 as that confuses set-auto-coding, so insist on the head-read
1447 returning the full 1024 bytes. Let lseek compute the tail offset;
1448 less work for us. Do not ignore I/O errors when reading the tail.
1450 * xdisp.c: Minor style fixes.
1451 (init_iterator): Hoist assignment out of if-expression.
1452 (markpos_of_region): Callers now test for sign, not for -1.

1471 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1472 files, fixing a regression from 24.2.

1475 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1477 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1478 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1479 Remove unnecessary S_ISLNK test, as (contra the comments) this
1480 function can't copy symlinks. Improve quality of error message
1481 when attempting to copy files that are neither regular files nor

1492 2012-12-12 Daniel Colascione <dancol@dancol.org>
1494 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1495 the dumped Emacs is not a sparse file, greatly improving Cygwin
1496 "make bootstrap" performance.
1498 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1500 * inotify.c (inotify_callback): Generate an Emacs event for every
1501 incoming inotify event.
1503 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1505 * xdisp.c (handle_face_prop): Fix logic of computing
1506 it->start_of_box_run_p.
1507 (append_space_for_newline): If the glyph row is R2L, reset the
1508 iterator's end_of_box_run_p flag before prepending the space glyph.
1509 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1510 iterator's start_of_box_run_p flag before prepending the stretch.
1511 (append_glyph, produce_image_glyph, append_composite_glyph)
1512 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1513 left_box_line_p and right_box_line_p flags of the glyph for R2L
1514 glyph rows. (Bug#13011)

1519 if changed buffer is not shown in a window.
1520 * insdel.c (prepare_to_modify_buffer): Likewise.
1521 * window.c (replace_buffer_in_windows_safely): Do nothing
1522 if buffer is not shown in a window.

1526 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1528 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1529 encoded_file_name, which is what it is.
1531 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1533 Consistently use marker_position and marker_byte_position.
1534 * fringe.c (Ffringe_bitmaps_at_pos):

1557 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1560 * w32fns.c (cache_system_info): Initialize the global hinst
1561 variable here so various initialization calls DTRT.
1563 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1564 (hinst): Remove unneeded extern declaration.
1565 (_start): Remove initialization of above variables; remove
1566 initialization of hinst, as cache_system_info now does that.

1710 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1712 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1713 * alloc.c (xputenv): New function.
1714 * dbusbind.c (Fdbus_init_bus):
1716 * xterm.c (x_term_init):
1717 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

1753 Remove USG and vlimit methods; no longer used these days.
1754 Add #error catchall just in case.
1756 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1757 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,

1785 * frame.c (make_frame): Do not set window's buffer to t.
1786 * window.c (Fsplit_window_internal): Likewise. Previously it was
1787 used to indicate that the window is being set up. Now we use
1788 set_window_buffer for all new windows, so the condition in ...
1789 (Fset_window_buffer): ... is always true and can be removed.
1791 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1793 Convenient macro to check whether the buffer is hidden.
1794 * buffer.h (BUFFER_HIDDEN_P): New macro.

1803 loop and return zero. (Bug#13086)
1805 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1807 * frame.h (x_char_width, x_char_height): Remove prototypes.

1820 Fix a recently-introduced delete-process race condition.
1821 * callproc.c, process.h (record_kill_process):
1822 New function, containing part of the old call_process_kill.
1823 (call_process_kill): Use it.
1824 This does not change call_process_kill's behavior.
1825 * process.c (Fdelete_process): Use record_kill_process to fix a
1826 race condition that could cause Emacs to lose track of a child.
1828 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1830 Avoid code duplication between prev_frame and next_frame.
1831 * frame.c (candidate_frame): New function. Add comment.
1832 (prev_frame, next_frame): Use it. Adjust comment.
1834 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1836 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1837 fails, signal an error instead of continuing with an empty
1839 Encode expanded temp file pattern before passing it to mkstemp or
1842 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1843 Encode the file name before passing it to dostounix_filename, in
1844 case it will downcase it (under w32-downcase-file-names).
1847 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1849 Minor call-process cleanups.
1850 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1851 at the same time as other platforms, to simplify analysis.
1852 No need for fd0_volatile since we have synch_process_fd.
1853 Avoid needless emacs_close; arg is always negative.
1855 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1857 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1860 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1862 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1863 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

1870 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1871 members to a bitfields.
1873 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1875 Don't let call-process be a zombie factory (Bug#12980).
1876 Fixing this bug required some cleanup of the signal-handling code.
1877 As a side effect, this change also fixes a longstanding rare race
1878 condition whereby Emacs could mistakenly kill unrelated processes,
1879 and it fixes a bug where a second C-g does not kill a recalcitrant
1880 synchronous process in GNU/Linux and similar platforms.
1881 The patch should also fix the last vestiges of Bug#9488,
1882 a bug which has mostly been fixed on the trunk by other changes.
1883 * callproc.c, process.h (synch_process_alive, synch_process_death)
1884 (synch_process_termsig, sync_process_retcode):
1885 Remove. All uses removed, to simplify analysis and so that
1886 less consing is done inside critical sections.
1887 * callproc.c (call_process_exited): Remove. All uses replaced
1888 with !synch_process_pid.
1889 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1890 These take the role of what used to be in unwind-protect arg.
1892 (block_child_signal, unblock_child_signal):
1893 New functions, to avoid races that could kill innocent-victim processes.
1894 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1895 (call_process_kill): Record killed processes as deleted, so that
1896 zombies do not clutter up the system. Do this inside a critical
1897 section, to avoid a race that would allow the clutter.
1898 (call_process_cleanup): Fix code so that the second C-g works again
1899 on common platforms such as GNU/Linux.
1900 (Fcall_process): Create the child process in a critical section,
1901 to fix a race condition. If creating an asynchronous process,
1902 record it as deleted so that zombies do not clutter up the system.
1903 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1904 light of these changes. Omit unnecessary call to emacs_close
1905 before failure, as the unwind-protect code does that.
1906 * callproc.c (call_process_cleanup):
1907 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1908 * process.c (record_deleted_pid): New function, containing
1909 code refactored out of Fdelete_process.
1910 (Fdelete_process): Use it.
1911 (process_status_retrieved): Remove. All callers changed to use
1912 child_status_change.
1913 (record_child_status_change): Remove, folding its contents into ...
1914 (handle_child_signal): ... this signal handler. Now, this
1915 function is purely a handler for SIGCHLD, and is not called after
1916 a synchronous waitpid returns; the synchronous code is moved to
1917 wait_for_termination. There is no need to worry about reaping
1918 more than one child now.
1919 * sysdep.c (get_child_status, child_status_changed): New functions.
1920 (wait_for_termination): Now takes int * status and bool
1921 interruptible arguments, too. Do not record child status change;
1922 that's now the caller's responsibility. All callers changed.
1923 Reimplement in terms of get_child_status.
1924 (wait_for_termination_1, interruptible_wait_for_termination):
1925 Remove. All callers changed to use wait_for_termination.
1926 * syswait.h: Include <stdbool.h>, for bool.
1927 (record_child_status_change, interruptible_wait_for_termination):
1929 (record_deleted_pid, child_status_changed): New decls.
1930 (wait_for_termination): Adjust to API changes noted above.
1932 * bytecode.c, lisp.h (Qbytecode): Remove.
1933 No longer needed after 2012-11-20 interactive-p changes.
1935 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1937 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1938 the scroll margin, move point outside the margin. (Bug#13055)

1942 * gtkutil.c (my_log_handler): New function.
1943 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1945 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1947 * lisp.h (modify_region): Rename to...
1948 (modify_region_1): ...new prototype.
1949 * textprop.c (modify_region): Now static. Adjust users.
1950 * insdel.c (modify_region): Rename to...
1951 (modify_region_1): ...new function to work with current buffer.
1952 Adjust comment and users. Use true and false for booleans.
1954 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1956 * alloc.c (free_save_value): New function.
1957 (safe_alloca_unwind): Use it.
1958 * lisp.h (free_save_value): New prototype.
1959 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1961 (save_excursion_restore): Adjust to match saved data structure.
1962 Use free_save_value to offload some work from GC. Drop obsolete
1965 2012-12-03 Chong Yidong <cyd@gnu.org>
1967 * fileio.c (Vauto_save_list_file_name): Doc fix.
1969 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1971 * w32fns.c: Remove prototype of atof.
1972 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1974 (file_dialog_callback): Make it UINT_PTR.
1976 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1979 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1980 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1983 2012-12-03 Glenn Morris <rgm@gnu.org>
1985 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1987 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1989 Fix xpalloc confusion after memory is exhausted.
1990 * alloc.c (xpalloc): Comment fix.
1991 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1992 and signals an error, do not clear charset_table_size, as
1993 charset_table is still valid.
1994 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1996 Use execve to avoid need to munge environ (Bug#13054).
1997 * callproc.c (Fcall_process):
1998 * process.c (create_process):
1999 Don't save and restore environ; no longer needed.
2000 * callproc.c (child_setup):
2001 Use execve, not execvp, to preserve environ.
2003 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2005 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2007 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2009 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2010 display for sliced images (Bug#10500).
2012 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2014 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2016 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2017 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2019 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2021 * xdisp.c (window_outdated): Remove eassert since it hits
2022 some suspicious corner cases (see Bug#13007 and Bug#13012).
2023 (mode_line_update_needed): New function.
2024 (redisplay_internal, redisplay_window): Use it.

2028 (buffer_shared_and_changed): ...near to its real use.
2030 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2032 * callproc.c (Fcall_process): Don't misreport vfork failure.
2034 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2036 * callproc.c (Fcall_process): Fix vfork portability problems.
2037 Do not assume that fd[0], count, filefd, and save_environ survive
2038 vfork. Fix bug whereby wrong errno value could be reported for
2039 pipe failure. Some minor cleanups, too, as follows. Move buf and
2040 bufsize to the context where they're needed. Change new_argv to
2041 be of type char **, as this is more convenient and avoids casts.
2042 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2043 Now local constants, not macros.
2045 2012-11-18 Kenichi Handa <handa@gnu.org>
2047 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2048 for the variable "f".

2052 * font.c (font_unparse_xlfd): Exclude special characters from the
2053 generating XLFD name.

2078 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2079 highlighting on the frame was cleared. Prevents assertion
2080 violations when repeatedly clicking on the "Top" link of the
2081 "bread-crumbs" in Info buffers.

2095 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2096 between bpos_covered and bpos_max. This fixes cursor display when
2097 several display strings follow each other.
2099 * .gdbinit (pgx): If the glyph's object is a string, display the
2100 pointer to string data, rather than the value of the string object
2101 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2103 * indent.c (Fvertical_motion): If the starting position is covered
2104 by a display string, return to one position before that, to avoid
2105 overshooting it inside move_it_to. (Bug#12930)
2107 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2109 * frame.h (struct frame): Remove display_preempted member

2119 * xterm.h (struct x_output): Drop outdated #if 0 code.
2120 Use bitfields for explicit_parent, asked_for_visible,
2121 has_been_visible and net_wm_state_hidden_seen members.
2123 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2125 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2126 of a literal "/". (Bug#12955)
2127 (gl-stamp): Invoke fc.exe directly, not through cmd.
2129 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

2132 * dired.c: Assume HAVE_DIRENT_H.
2133 (NAMLEN): Remove, replacing with ...
2134 (dirent_namelen): New function. All uses changed. Use the GNU macro
2135 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2136 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2137 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2138 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2140 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2141 * ndir.h: Rename to ../nt/inc/dirent.h.
2142 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2143 Do not include <dirent.h>; no longer needed.
2144 * w32.c: Include <dirent.h> rather than "ndir.h".
2146 2012-11-23 Chong Yidong <cyd@gnu.org>
2148 * xftfont.c (xftfont_open): Remove duplicate assignment.
2150 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2152 * alloc.c (Fgarbage_collect): Unblock input after clearing
2153 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2154 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2155 * msdos.c (IT_frame_up_to_date): Use it here...
2156 * w32term.c (w32_frame_up_to_date): ...here...
2157 * xterm.c (XTframe_up_to_date): ...and here...
2158 * nsterm.m (ns_frame_up_to_date): ...but not here.
2159 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2161 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

2172 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2174 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2175 with Windows system header.
2177 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2179 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

2196 * emacs.c (main): Set the G_SLICE environment variable for all
2197 Cygwin builds, not just GTK builds. See
2198 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2200 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2202 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2203 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2204 Define for the MSVC compiler.
2206 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2208 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2209 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2210 dostounix_filename. Prevents crashes down the road, because
2211 dostounix_filename assumes it gets a unibyte string.
2212 Reported by Michel de Ruiter <michel@sentient.nl>, see
2213 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

2244 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2245 (syms_of_eval): Remove corresponding defsubr.
2246 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2248 2012-11-19 Daniel Colascione <dancol@dancol.org>
2250 * w32fns.c (Fx_file_dialog):
2251 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2252 cygwin_convert_file_name*.
2254 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2255 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2257 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2259 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2261 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2263 * w32select.c: Include w32common.h before w32term.h, so that
2264 windows.h gets included before w32term.h uses some of its
2265 features, see below.
2267 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2269 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2278 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2280 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2281 Needed following 2012-10-20 change. (Bug#12902)
2283 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2285 * w32proc.c (waitpid): Remove unused label get_result.
2287 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2289 * makefile.w32-in (SYSWAIT_H): New macro.
2290 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2291 ($(BLD)/sysdep.$(O)): Update dependencies.
2293 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>

2296 * callproc.c (relocate_fd): Assume F_DUPFD.
2297 * emacs.c, term.c (O_RDWR): Remove.
2298 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2299 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2300 * nsterm.m: Assume <fcntl.h> exists.
2301 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2302 (create_pty, Fmake_network_process, server_accept_connection)
2303 (wait_reading_process_output, init_process_emacs):
2305 (wait_reading_process_output): Put in a special case for WINDOWSNT
2306 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2307 It's not clear this is needed, but it's a more-conservative change.
2308 (create_process): Assume FD_CLOEXEC.
2309 (create_process, create_pty): Assume O_NOCTTY.
2310 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2311 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2312 Omit if not DOS_NT, since F_GETFL is not defined there.
2313 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2314 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2316 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2317 lack it, since gnulib guarantees this.
2318 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2320 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2322 * w32.c (faccessat): Pretend that directories have the execute bit
2323 set. Emacs expects that, e.g., in files.el:cd-absolute.
2325 * w32proc.c (create_child): Don't clip the PID of the child
2326 process to fit into an Emacs integer, as this is no longer a
2328 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2329 reaping only the process specified by PID argument, if that is
2330 positive. Use PID instead of dead_child to know which process to
2331 reap. Wait for the child to die only if WNOHANG is not in
2333 (sys_select): Don't set dead_child.
2335 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2336 as it is no longer needed.
2338 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2340 (record_child_status_change): Remove the setting of
2341 record_at_most_one_child for the !WNOHANG case.
2343 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2345 Fix problems in ns port found by static checking.
2346 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2347 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2348 not to process group.
2349 (ns_select): Use emacs_write, not write, as that's more robust
2350 in the presence of signals.
2351 (fd_handler:): Check for read errors.
2353 2012-11-16 Glenn Morris <rgm@gnu.org>
2355 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2357 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2359 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2361 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2363 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2364 use the same value of thread handle.
2365 (start_timer_thread): If the timer thread exited (due to error),
2366 clean up by closing the two handles it used. Duplicate the caller
2367 thread's handle here, so it gets duplicated only once, when
2368 launching the timer thread. Set priority of the timer thread, not
2370 (getitimer): Don't duplicate the caller thread's handle here.
2373 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2375 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2378 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2380 Remove no-longer-used pty_max_bytes variable.
2381 * process.c (pty_max_bytes): Remove; unused.
2382 (send_process): Do not set it.
2384 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2386 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2387 Update dependencies.
2389 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2391 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2392 This follows up on the 2012-09-29 patch that removed indirection
2393 for the 'function' field. Reported by Sergey Vinokurov in
2394 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2396 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2398 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2399 different name, as the MS runtime does not have such a function,
2400 and probably never will.) All callers changed. Ignore DIRFD
2401 value if PATH is an absolute file name, to match Posix spec
2402 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2405 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2407 * xdisp.c (echo_area_display, redisplay_internal):
2408 Omit redundant check whether frame_garbaged is set.
2410 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2412 Use faccessat, not access, when checking file permissions (Bug#12632).
2413 This fixes a bug that has been present in Emacs since its creation.
2414 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2415 which must set some sort of record. (Torek's bug report was against
2416 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2417 same common flaw.) See Torek's Usenet posting
2418 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2419 Posted: Fri Apr 8 14:18:56 1983.
2420 * Makefile.in (LIB_EACCESS): New macro.
2422 * callproc.c (init_callproc):
2423 * charset.c (init_charset):
2424 * fileio.c (check_existing, check_executable, check_writable)
2426 * lread.c (openp, load_path_check):
2427 * process.c (allocate_pty):
2429 Use effective UID when checking permissions, not real UID.
2430 * callproc.c (init_callproc):
2431 * charset.c (init_charset):
2432 * lread.c (load_path_check, init_lread):
2433 Test whether directories are accessible, not merely whether they exist.
2434 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2435 * fileio.c (check_existing, check_executable, check_writable)
2437 Use symbolic names instead of integers for the flags, as they're
2439 (check_writable): New arg AMODE. All uses changed.
2440 Set errno on failure.
2441 (Ffile_readable_p): Use faccessat, not stat + open + close.
2442 (Ffile_writable_p): No need to call check_existing + check_writable.
2443 Just call check_writable and then look at errno. This saves a syscall.
2444 dir should never be nil; replace an unnecessary runtime check
2445 with an eassert. When checking the parent directory of a nonexistent
2446 file, check that the directory is searchable as well as writable, as
2447 we can't create files in unsearchable directories.
2448 (file_directory_p): New function, which uses 'stat' on most platforms
2449 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2450 (Ffile_directory_p, Fset_file_times): Use it.
2451 (file_accessible_directory_p): New function, which uses a single
2452 syscall for efficiency.
2453 (Ffile_accessible_directory_p): Use it.
2454 * xrdb.c (file_p): Use file_directory_p.
2455 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2456 * lread.c (openp): When opening a file, use fstat rather than
2457 stat, as that avoids a permissions race. When not opening a file,
2458 use file_directory_p rather than stat.
2459 (dir_warning): First arg is now a usage string, not a format.
2460 Use errno. All uses changed.
2461 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2462 that merely introduced a race.
2463 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2464 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2465 and similarly for the other O_* flags.
2466 * w32.c (sys_faccessat): Rename from sys_access and switch to
2467 faccessat's API. All uses changed.
2468 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2469 (magic_db): Rename from magic_file_p.
2470 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2471 char *, so that we don't have to test for file existence
2472 separately from opening the file for reading. This removes a race
2473 fixes a permission-checking problem, and simplifies the code.
2475 (file_p): Remove; no longer needed.
2477 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2479 Omit glyphs initialization at startup.
2480 * dispnew.c (glyphs_initialized_initially_p): Remove.
2481 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2482 (Fredraw_frame): Move actual code from here...
2483 (redraw_frame): ...to here. Add eassert. Adjust comment.
2484 (Fredraw_display): Use redraw_frame.
2485 * xdisp.c (clear_garbaged_frames): Likewise.
2487 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2489 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2490 passed to pint2str and pint2hrstr to be at most the size of the
2491 frame's decode_mode_spec_buffer. This avoids crashes with very
2492 large values of FIELD_WIDTH argument to decode_mode_spec.
2495 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2497 Fix a race with verify-visited-file-modtime (Bug#12863).
2498 Since at least 1991 Emacs has ignored an mtime difference of no
2499 more than one second, but my guess is that this was to work around
2500 file system bugs that were fixed long ago. Since the race is
2501 causing problems now, let's remove that code.
2502 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2503 whose time stamp is off by no more than a second. Insist that the
2504 file time stamps match exactly.
2506 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2508 * frame.h (struct frame): Convert external_tool_bar member to
2509 1-bit unsigned bitfield.
2510 * termhooks.h (struct terminal): Remove mouse_moved member since
2511 all users are long dead. Adjust comment on mouse_position_hook.
2513 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2515 Simplify by using FOR_EACH_FRAME here and there.
2516 * frame.c (next_frame, prev_frame, other_visible_frames)
2517 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2518 * w32term.c (x_window_to_scroll_bar): Likewise.
2519 * window.c (window_list): Likewise.
2520 * xdisp.c (x_consider_frame_title): Likewise.
2521 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2522 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2523 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2524 * xmenu.c (menubar_id_to_frame): Likewise.
2525 * xselect.c (frame_for_x_selection): Likewise.
2526 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2527 (x_window_to_menu_bar): Likewise.
2528 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2530 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2532 * data.c (Qdefalias_fset_function): Now static.
2534 Another tweak to vectorlike_header change.
2535 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2536 Remove, and replace all uses with ...
2537 (next_in_free_list, set_next_in_free_list):
2538 New functions, which respect C's aliasing rules better.
2540 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2542 * window.c (list4i): Rename from 'quad'. All uses changed.
2543 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2545 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2547 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2548 warning about mixing declarations and code in ISO C90.
2550 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2552 * window.c (Fsplit_window_internal): Set combination limit of
2553 new parent window to t iff Vwindow_combination_limit is t;
2554 fixing a regression introduced with the change from 2012-09-22.
2555 (Fset_window_combination_limit): Fix doc-string.
2557 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2559 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2560 amount when the scroll margins are too large. When scrolling
2561 backwards in the buffer, give up if cannot reach point or the
2562 scroll margin within a reasonable number of screen lines.
2563 Fixes point position in window under scroll-up/down-aggressively when
2564 point is positioned many lines beyond the window top/bottom.
2567 * ralloc.c (relinquish): If real_morecore fails to return memory
2568 to the system, don't crash; instead, leave the last heap
2569 unchanged and return. (Bug#12774)
2571 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2573 * lisp.h (AUTOLOADP): New macro.
2574 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2575 * data.c (Ffset): Remove special ad-advice-info handling.
2576 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2578 (Finteractive_form): Simplify.
2579 (Fquo): Don't insist on having at least 2 arguments.
2580 (Qdefalias_fset_function): New var.
2582 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2584 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2586 * nsfont.m (Qcondensed, Qexpanded): New variables.
2587 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2588 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2590 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2592 Fix recently introduced crash on MS-Windows (Bug#12839).
2593 * w32term.h (struct scroll_bar): Use convenient header.
2594 (SCROLL_BAR_VEC_SIZE): Remove.
2595 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2597 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2599 Tweak last vectorlike_header change.
2600 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2601 vectorlike object on the free list. This is introduced to avoid
2602 some (but not all) pointer casting and aliasing problems, see
2603 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2604 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2606 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2608 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2610 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2611 been removed, so remove them here also.
2613 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2615 * doc.c (Fdocumentation): Handle new property
2616 dynamic-docstring-function to replace the old ad-advice-info.
2618 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2620 * fns.c (Qeql, hashtest_eq): Now static.
2622 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2624 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2625 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2626 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2627 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2629 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2631 Use same hash function for hashfn_profiler as for hash_string etc.
2632 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2633 * lisp.h (sxhash_combine): New inline function, with the contents
2634 of the old SXHASH_COMBINE.
2635 * profiler.c (hashfn_profiler): Use it, instead of having a
2636 special hash function containing a comparison that always yields 1.
2638 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2640 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2641 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2642 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2645 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2647 * image.c (xpm_make_color_table_h): Fix compiler error because
2648 make_hash_table changed.
2650 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2652 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2654 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2656 Use ad-hoc comparison function for the profiler's hash-tables.
2657 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2658 (make_log): Use them.
2659 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2660 call Fequal any more.
2661 (Ffunction_equal): New function.
2662 (cmpfn_profiler, hashfn_profiler): New functions.
2663 (syms_of_profiler): Initialize them.
2664 * lisp.h (struct hash_table_test): New struct.

2669 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2670 (hash_lookup, hash_remove_from_table): Move assertion checking of
2671 hashfn result here. Check hash-equality before calling cmpfn.

2678 * print.c (print_object): Adjust to new hash-table struct.
2679 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2681 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2683 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2684 value of w32-scroll-lock-modifier is neither nil nor one of the
2685 known key modifiers. (Bug#12806)
2687 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2689 Shrink struct vectorlike_header to the only size field.
2690 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2692 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2693 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2694 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2695 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2696 information from the vector header. Adjust comment.
2697 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2698 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2700 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.

2704 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
2705 (sweep_string, lisp_malloc): Remove useless prototypes.
2706 (enum mem_type): Adjust comment.
2707 (NEXT_IN_FREE_LIST): New macro.
2708 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2709 (Fmake_bool_vector): Likewise.
2710 (struct large_vector): New type to represent allocation unit for
2711 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2712 (large_vectors): Change type to struct large_vector.
2713 (allocate_vector_from_block): Simplify.
2714 (PSEUDOVECTOR_NBYTES): Replace with...
2715 (vector_nbytes): ...new function. Adjust users.
2716 (sweep_vectors): Adjust processing of large vectors.
2717 (allocate_vectorlike): Likewise.
2718 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2719 Add easserts. Adjust XSETPVECTYPESIZE usage.
2720 (allocate_buffer): Use BUFFER_PVEC_INIT.
2721 (live_vector_p): Adjust to match large vector.
2722 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2723 * buffer.h (struct buffer): Add next member.
2724 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2726 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2727 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2728 (copy_hash_table): Adjust to match vector header change.
2729 * lread.c (defsubr): Use XSETPVECTYPE.
2730 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2731 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2732 (xvecsize): New command.
2734 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2736 * keyboard.c (event_to_kboard): Do not dereference
2737 frame_or_window field of SELECTION_REQUEST_EVENT
2738 and SELECTION_CLEAR_EVENT events (Bug#12814).
2739 * xterm.h (struct selection_input_event): Adjust comment.
2741 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2743 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2744 such as Scroll Lock, if the respective keys are treated as
2745 function keys, not as modifiers. This avoids destroying non-ASCII
2746 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2748 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2750 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2752 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2754 Restore some duplicate definitions (Bug#12814).
2755 This undoes part of the 2012-11-03 changes. Some people build
2756 with plain -g rather than with -g3, and they need the duplicate
2757 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2758 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2759 Define as macros, as well as as enums or as constants.
2761 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2763 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2764 to keypad keys (Bug#12816).
2766 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2768 Minor adjustments of recently-changed frame functions.
2769 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2770 known to be a frame (we're in the FRAMEP branch).
2771 * lisp.h (Qframep): Remove decl. frame.h declares this.
2772 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2773 since they're meant for Lisp fixnum values.
2775 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2777 * window.c (Fwindow_combination_limit): Revert to the only
2778 required argument and adjust docstring as suggested in
2779 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2780 by Martin Rudalics <rudalics@gmx.at>.
2782 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2784 Widely used frame validity and checking functions.
2785 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2786 * frame.c (decode_live_frame, decode_any_frame): New functions.
2787 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2788 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2789 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2790 (Fframe_pointer_visible_p): Use decode_any_frame.

2794 (Fframe_focus): Likewise. Allow zero number of arguments.
2796 (frame_buffer_list, frame_buffer_predicate): Remove.
2797 * lisp.h (frame_buffer_predicate): Remove prototype.

2799 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2800 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2801 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)

2826 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2827 (Fwindow_combination_limit): Allow zero number of arguments.
2829 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2831 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2833 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2834 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2835 file descriptor 2 for standard error. (Bug#12805)
2837 2012-11-05 Chong Yidong <cyd@gnu.org>
2839 * process.c (wait_reading_process_output): Revert previous change.
2841 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2843 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2844 This removes code that has been obsolete since around 1990.
2845 * callproc.c (Fcall_process):
2847 * process.c (create_process):
2848 * term.c (dissociate_if_controlling_tty):
2849 Assume setsid exists.
2850 * callproc.c (child_setup): Assume setpgid exists and behaves as
2851 per POSIX.1-1988 or later.
2852 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2853 * emacs.c (shut_down_emacs):
2854 * sysdep.c (sys_suspend, init_foreground_group):
2855 Assume getpgrp behaves as per POSIX.1-1998 or later.
2856 * msdos.c (setpgrp): Remove.
2857 (tcgetpgrp, setpgid, setsid): New functions.
2858 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2859 * term.c (no_controlling_tty): Remove; unused.
2860 * w32proc.c (setpgrp): Remove.
2861 (setsid, tcgetpgrp): New functions.
2863 Simplify by assuming __fpending.
2864 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2865 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2866 Do not assume that __fpending's result fits in int.
2868 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2870 Remove EMACS_OUTQSIZE+sleep hack.
2871 * dispnew.c (update_frame_1): Remove hack for terminals slower
2872 than 2400 bps, which throttled Emacs by having it sleep.
2873 This code hasn't worked since at least 2007, when the multi-tty stuff
2874 was added, and anyway those old terminals are long dead.
2875 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2876 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2878 Fix data-loss with --version (Bug#9574).
2879 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2880 as we can't assume that emacs_strerror is initialized, and strerror
2881 is good enough here.
2882 (main): Invoke atexit earlier, to catch earlier instances of
2883 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2885 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2887 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2888 (keyDown): Remap keypad keys to X11 virtual key codes.
2890 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2892 Fix data-loss with --batch (Bug#9574).
2893 * emacs.c: Include <close-stream.h>.
2894 (close_output_streams): New function.
2895 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2896 and handles errors appropriately.
2897 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2900 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2901 The symptom is a diagnostic "GLib-WARNING **: In call to
2902 g_spawn_sync(), exit status of a child process was requested but
2903 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2904 waitpid(), so exit status can't be returned." The diagnostic
2905 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2906 The real bug is a race condition between Emacs and glib: Emacs
2907 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2908 so that glib can't find it. Work around the bug by invoking
2909 waitpid only on subprocesses that Emacs itself creates.
2910 * process.c (create_process, record_child_status_change):
2911 Don't use special value -1 in pid field, as the caller now must
2912 know the pid rather than having the callee infer it.
2913 The inference was sometimes incorrect anyway, due to another race.
2914 (create_process): Set new 'alive' member if child is created.
2915 (process_status_retrieved): New function.
2916 (record_child_status_change): Use it.
2917 Accept negative 1st argument, which means to wait for the
2918 processes that Emacs already knows about. Move special-case code
2919 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2920 processes that have already been waited for, by testing and
2921 clearing new 'alive' member.
2922 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2923 now does this internally.
2924 (handle_child_signal): Let record_child_status_change do all
2925 the work, since we do not want to reap all exited child processes,
2926 only the child processes that Emacs itself created.
2927 * process.h (Lisp_Process): New boolean member 'alive'.
2929 Omit duplicate definitions no longer needed with gcc -g3.
2930 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2931 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2932 Define only as macros. There's no longer any need to also define
2933 these symbols as enums or as constants, since we now assume
2934 gcc -g3 when debugging.
2936 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2938 * lisp.mk: Adjust comments to the fact that term/internal is now
2939 loaded from loadup.el.
2941 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2942 (msdos_fatal_signal): New function.
2943 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2946 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2947 for GCC versions before 4.
2948 (emacs_raise): Define to call msdos_fatal_signal.
2950 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2951 iterator when starting in the middle of a display or overlay
2954 2012-11-03 Chong Yidong <cyd@gnu.org>
2956 * process.c (wait_reading_process_output): Clean up the last
2959 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2961 * process.c (wait_reading_process_output): Avoid a race condition
2962 with SIGIO delivery (Bug#11536).
2964 2012-11-03 Chong Yidong <cyd@gnu.org>
2966 * buffer.c (cursor_type): Untabify docstring.
2968 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2970 * frame.h (struct frame): Drop can_have_scroll_bars member
2971 which is meaningless for a long time. Adjust comments.
2972 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2973 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2975 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2977 * window.c (decode_next_window_args): Update window arg after
2978 calling decode_live_window and so fix crash reported at
2979 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2980 by Juanma Barranquero <lekktu@gmail.com>.
2981 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2982 * font.c (Ffont_at): Likewise.
2984 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2986 * widget.c (resize_cb): New function.
2987 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2988 (EmacsFrameResize): Check if all is up to date before changing frame
2991 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2993 Implement backtrace output for fatal errors on MS-Windows.
2994 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2995 (BACKTRACE_LIMIT_MAX): New macro.
2996 (w32_backtrace): New function.
2997 (emacs_abort): Use w32_backtrace when the user chooses not to
2998 attach a debugger. Update the text of the abort dialog.
3000 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3002 Window-related stuff cleanup here and there.
3003 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3004 Use decode_any_window.
3005 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3006 * xdisp.c (Fformat_mode_line): Likewise.
3007 * font.c (Ffont_at): Use decode_live_window.
3008 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3009 * window.c (decode_next_window_args): Likewise.
3010 (decode_any_window): Remove static.
3011 * window.h (decode_any_window): Add prototype.
3012 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3013 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3016 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3018 Remove pad from struct input_event.
3019 * termhooks.h (struct input_event): Remove padding field.
3021 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3022 member is never cons for a long time. Adjust comment.
3023 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3024 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3025 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3026 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3028 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3030 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3032 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3034 Fix crash when using Emacs as commit editor for git (Bug#12697).
3035 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3036 and it is configured in conf_post.h.
3037 (Fcall_process): Don't invoke both setsid and setpgid; the former
3038 is enough, if it exists.
3039 * callproc.c (Fcall_process, child_setup):
3040 * process.c (create_process): Use setpgid.
3041 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3043 * dispnew.c (init_display): Initialize the foreground group
3044 if we are running a tty display.
3045 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3046 * lisp.h (init_foreground_group): New decl.
3047 * sysdep.c (inherited_pgroup): New static var.
3048 (init_foreground_group, tcsetpgrp_without_stopping)
3049 (narrow_foreground_group, widen_foreground_group): New functions.
3050 (init_sys_modes): Narrow foreground group.
3051 (reset_sys_modes): Widen foreground group.
3053 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3055 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3057 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3059 * minibuf.c (read_minibuf): Restore current buffer since
3060 choose_minibuf_frame calling Fset_frame_selected_window may
3061 change it (Bug#12766).
3063 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3065 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3067 2012-10-30 Kenichi Handa <handa@gnu.org>
3069 * font.c (Ffont_at): If WINDOW is specified and it is not
3070 displaying the current buffer, signal an error.
3072 2012-10-29 Daniel Colascione <dancol@dancol.org>
3074 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3075 In preparation for fixing bug#12739, move these functions from
3078 * coding.h, coding.c: ... to here, and compile them only when
3079 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3080 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3082 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3084 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3085 (timer_loop, getitimer, setitimer): Use it instead of
3086 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3088 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3091 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3093 * nsterm.m (NO_APPDEFINED_DATA): New define.
3094 (last_appdefined_event_data): New variable
3095 (last_appdefined_event): Remove.
3096 (ns_select): Initialize t from last_appdefined_event_data instead
3097 of [last_appdefined_event data1].
3098 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3099 remove last_appdefined_event (Bug#12698).
3101 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3103 * frame.c (x_set_font): Catch internal error.
3105 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3107 Avoid overflow in w32 implementation of interval timers.
3108 When possible, for ITIMER_PROF count only times the main thread
3110 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3111 'volatile ULONGLONG' types. All the other data which was
3112 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3113 (GetThreadTimes_Proc): New typedef.
3114 (w32_get_timer_time): New function, returns a suitable time value
3116 (timer_loop): Enter critical section when accessing ULONGLONG
3117 values of the itimer_data struct, as these accesses are no longer
3118 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3119 Remove unused variable.
3120 (init_timers): Initialize s_pfn_Get_Thread_Times.
3121 (start_timer_thread): Don't assign itimer->caller_thread here.
3122 (getitimer): Assign itimer->caller_thread here.
3123 (setitimer): Always call getitimer to get the value of ticks_now.
3124 (sys_spawnve): Avoid compiler warning about format mismatch.
3126 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3128 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3129 mouse movement events if the menu bar is active. This avoids
3130 producing a busy "hour-glass" cursor by Windows if the mouse
3131 pointer is positioned over a tooltip shown for some menu item.
3133 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3135 Don't assume process IDs fit in int.
3136 * emacs.c (shut_down_emacs) [!DOS_NT]:
3137 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3138 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3139 Use pid_t, not int, to store process IDs, as 'int'
3140 is not wide enough on a few platforms (e.g., AIX and IRIX).
3142 2012-10-23 Kenichi Handa <handa@gnu.org>
3144 The following change is to make face-font-rescale-alist work
3145 correctly for non-ASCII fonts.
3147 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3148 (font_open_for_lface): Handle Vface_font_rescale_alist.
3150 2012-10-23 Chong Yidong <cyd@gnu.org>
3152 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3154 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3156 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3158 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3160 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3163 2012-10-21 Glenn Morris <rgm@gnu.org>
3165 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3167 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3169 Port to OpenBSD 5.1.
3170 * frame.c (Fmouse_position, Fmouse_pixel_position):
3171 * xdisp.c (produce_stretch_glyph):
3172 Declare local vars only when they're needed.
3173 This is clearer and avoids a warning on OpenBSD about unused vars.
3174 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3175 This is safer, and avoids OpenBSD warnings about unused vars.
3176 * keyboard.c (record_menu_key): Remove unnecessary decl.
3177 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3178 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3179 as our definition clashes with OpenBSD's.
3180 * xfaces.c (load_face_colors, check_lface_attrs)
3181 (get_lface_attributes_no_remap, get_lface_attributes)
3182 (lface_fully_specified_p, x_supports_face_attributes_p)
3183 (tty_supports_face_attributes_p, face_fontset, realize_face)
3184 (realize_x_face, realize_tty_face):
3185 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3186 merely Lisp_Object *. This is more informative and avoids
3187 a warning on OpenBSD about accessing beyond an object's size.
3189 2012-10-20 Chong Yidong <cyd@gnu.org>
3191 * lread.c (Fload): Doc fix (Bug#12592).
3193 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3195 * font.c (Ffont_at): Fix previous change.
3197 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3199 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3200 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3203 * alloc.c (NSTATICS): Decrease to 0x800.
3205 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
3207 * fns.c (Fnreverse): Include the problem element when signaling an
3210 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
3212 * nsterm.m (ns_select): Check writefds before call to
3213 FD_ISSET (Bug#12668).
3215 2012-10-18 Daniel Colascione <dancol@dancol.org>
3217 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3218 (staticpro): If we run out of staticpro slots, die with an
3219 informative error instead of just calling emacs_abort.
3221 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3223 Fix two flaws reported by Dmitry Antipov.
3224 * window.c (Ftemp_output_buffer_show): Remove.
3225 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
3226 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
3228 2012-10-17 Eli Zaretskii <eliz@gnu.org>
3230 * makefile.w32-in ($(BLD)/w32.$(O)):
3231 ($(BLD)/vm-limit.$(O)):
3233 ($(BLD)/unexw32.$(O)):
3234 ($(BLD)/fileio.$(O)):
3235 ($(BLD)/dispnew.$(O)): Update dependencies.
3237 * w32term.h (w32_initialize_display_info, initialize_w32_display):
3240 * w32proc.c: Include ctype.h.
3242 * w32.h (init_environment, check_windows_init_file)
3243 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
3244 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
3245 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
3246 (sys_link): Add prototypes.

3377 * fileio.c (check_existing): New function.
3378 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it

3477 Use unsigned for counter where wraparound-on-overflow is desired,
3478 since unsigned is guaranteed to have that behavior and signed is not.
3479 (read_char): Use ptrdiff_t for string length.
3480 (get_input_pending): Remove first argument, since it was always
3481 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3482 and behave as if it had that value. Return new value of
3483 input_pending. All callers changed.
3484 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3485 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3487 * keymap.c (push_key_description): Omit last arg, which was always 1.
3488 All callers changed.
3490 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3492 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3508 Don't include termopts.h.
3510 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3512 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3514 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3516 * commands.h (immediate_quit): Remove duplicate decl.
3518 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3520 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3525 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3527 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3528 match what GetLastError returns. Explain why the function is
3531 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3532 'is_tooltip_frame', to avoid confusion with its global namesake.
3534 2012-10-08 Daniel Colascione <dancol@dancol.org>
3536 * xdisp.c (start_hourglass): Call w32_note_current_window when
3537 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3538 build that caused Emacs to display the hourglass cursor forever.
3540 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3541 which is broken under remote desktop, calculate the number of
3542 colors available for a display based on the display's number of
3543 planes and number of bits per pixel per plane. (bug#10397).
3545 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3547 * nsfont.m (Vfonts_in_cache): New variable.
3548 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3549 are used. Add cached fonts to Vfonts_in_cache.
3550 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3552 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3554 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3556 (FONT_H): Define after FRAME_H.
3557 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3558 Update dependencies.
3560 * w32term.c: Remove leftover declaration of keyboard_codepage.
3562 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3564 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3565 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3566 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3567 (GLOBAL_SOURCES): Add cygw32.c.
3568 ($(BLD)/unexw32.$(O)):
3570 ($(BLD)/w32console.$(O)):
3571 ($(BLD)/w32fns.$(O)):
3572 ($(BLD)/w32heap.$(O)):
3573 ($(BLD)/w32menu.$(O)):
3574 ($(BLD)/w32proc.$(O)): Add w32common.h.
3576 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3578 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3580 2012-10-08 Daniel Colascione <dancol@dancol.org>
3582 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3583 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3584 accidental message numbering hole. Change other messages to
3587 * w32select.h (HAVE_W32SELECT): Remove.
3589 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3590 w32common.h instead of w32heap.h.
3592 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3593 (get_allocation_unit, get_processor_type, get_w32_major_version)
3594 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3595 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3596 (OS_NT, os_subtype, cache_system_info): Move declarations to
3599 * w32heap.c: Include w32common.h.
3600 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3601 (w32_minor_version, w32_build_number, w32_subtype):
3602 Remove duplicate definitions.
3604 * w32fns.c: Include w32common.h; include w32heap.h only in
3607 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3608 Use `report_file_error' instead of `error' in order to better
3609 inform users of what went wrong. Increase NTGUI_UNICODE file
3610 dialog box file name length to 32k, the maximum allowed by the NT
3613 * w32common.h: New file.
3614 (ROUND_UP, ROUND_DOWN, get_page_size)
3615 (get_allocation_unit, get_processor_type, get_w32_major_version)
3616 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3617 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3618 (OS_NT, os_subtype, cache_system_info): Move here.
3620 * unexw32.c, unexcw.c: Include w32common.h.
3622 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3623 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3624 to call syms_of_w32select.
3626 * cygw32.h: Remove obsolete EXFUN declarations.
3628 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3631 of w32inevt.o from SOME_MACHINE_OBJECTS.
3633 2012-10-08 Daniel Colascione <dancol@dancol.org>
3635 * image.c: Permanent fix for JPEG compilation issue --- limit
3636 jpeglib `boolean' redefinition to Cygwin builds.
3638 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3640 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3642 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3645 2012-10-08 Daniel Colascione <dancol@dancol.org>
3647 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3648 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3649 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3650 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3651 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3652 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3653 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3654 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3655 now a supported configuration.
3657 * Makefile.in: consolidate image variables into LIBIMAGE; add
3658 W32_OBJ and W32_LIBS. Compile new files.
3661 (_DebPrint) declare tracing facility for W32 debugging. We need
3662 to unify tracing later.
3664 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3665 unconditional use of W32 Unicode functions. Cygwin runs only on
3666 100% Unicode operating systems.
3668 * cygw32.c: New file. Define Cygwin-specific facilities.
3669 (Fcygwin_convert_path_to_windows)
3670 (Fcygwin_convert_path_from_windows): New user functions for
3671 accessing Cygwin path-munging routines.
3673 * cygw32.h: New file.
3674 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3675 UTF-16LE strings temporarily inside non-Lisp-visible string
3678 (w32_strerror): Just what it says on the tin.
3680 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3681 also run for Cygwin; both systems have the same problem with using
3682 GUI facilities in a forked child. Also call syms_of_cygw32,
3683 syms_of_w32select in correct places.
3685 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3686 needs fork-then-exec for daemon launching.
3688 * font.h: Include frame.h.
3690 * image.c: Use the image library cache machinery only when we're
3691 compiling for native WINDOWSNT; Cygwin can use shared libraries
3692 like any other Unixlike system.
3694 * keyboard.c: Clarify a comment regarding the input loop.
3696 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3697 functions directly instead of trying to detect at runtime that our
3698 host operating system supports them. We make this change for two
3699 reasons: Cygwin lacks support for the multibyte character
3700 conversion functions used by the legacy menu code, and Cygwin
3701 never needs to rely on non-Unicode APIs.
3703 * unexw32.c (hinst): Declare extern.
3705 * w32.c: Change header order;
3706 (w32_strerror): Move to w32fns.c because we need it for
3707 non-WINDOWSNT builds.
3709 * w32.h: Add #error macro to make sure we don't include w32.h for
3710 Cygwin builds. Remove w32select declarations.
3712 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3713 w32fns.c. w32console.c is WINDOWSNT-only.
3715 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3716 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3718 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3719 (w32_major_version, w32_minor_version, w32_build_number)
3720 (os_subtype, sound_type): Define here
3721 (w32_defined_color): Make color parameter const for consistency
3722 with other _defined_color functions.
3723 (w32_createwindow): Unconditionally call w32_init_class instead of
3724 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3725 through the code is complex and unnecessary because class
3726 registration is practically free.
3727 (w32_name_of_message): New EMACSDEBUG-only function.
3728 (Fset_message_beep): Move here
3729 (Fx_open_connection): Require that the display name for Windows be
3730 "w32" for consistency, emacsclient disambiguation, and maybe, one
3731 day, multi-window-system support.
3732 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3733 Cygwin files for W32 GUI facilities, since these clearly don't
3734 expect Cygwin names.
3735 (_DebPrint): Define.
3736 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3737 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3738 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3739 (w32_last_error): Remove.
3741 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3743 * w32heap.c (syspage_mask): Declare here.
3744 (cache_system_info): Remove.
3746 * w32inevt.c (faked_key): Define globally, not statically.
3747 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3748 (w32_console_toggle_lock_key): Move to w32fns.c.
3750 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3752 * w32proc.c (_DebPrint): Move to w32fns.c.
3753 * w32select.c: Include string.h, stdio.h for Cygwin.
3754 * w32select.h: New File.
3756 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3758 (w32_message_fd): New variable. Under Cygwin, holds the file
3759 descriptor the system used to tell us about pending thread
3762 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3763 that prevented compilation under non-WINDOWSNT systems.
3765 (w32_initialize): Open /dev/windows and assign it to
3766 w32_message_fd. Provide w32 feature.
3768 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3769 (WM_EMACS_INPUT_READY): add.
3770 (prepend_msg, w32_message_fd): Declare globally.
3773 (keyboard_handle): Use only when WINDOWSNT.
3774 (notify_msg_ready): New function. Posts a message to the main
3775 thread's message queue under CYGWIN, which wakes up the main
3776 thread from select(2) by making the /dev/windows file descriptor
3777 ready. Under WINDOWSNT, it sets an event the same way the old
3780 (post, prepend_msg): Actually call notify_msg_ready instead of
3781 setting the input event directly.
3783 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3785 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3786 but it still has blocs in it, don't return it to the system,
3787 instead of aborting. (Bug#12402)
3789 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3791 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3793 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3794 MAC_OS_X_VERSION_10_6.

3822 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3824 Improve sys_siglist detection.
3825 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3826 defined as a macro, as is done in Solaris.
3827 (sys_siglist_entries): New macro.
3828 (save_strsignal): Use it.
3829 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3830 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3832 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3834 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3835 fullscreen/Fullscreen.
3837 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3838 tobar_height is new.
3840 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3841 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3842 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

3851 (canBecomeMainWindow): New function.
3853 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3855 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3857 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3859 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3861 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3862 that time stamps of directories could also be changed.
3863 Don't request the too broad GENERIC_WRITE, only the more restrictive
3864 FILE_WRITE_ATTRIBUTES access rights.
3866 * fileio.c (Fset_file_times): Special-case ignoring errors for
3867 directories only on MSDOS, not on MS-Windows.
3869 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3871 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3873 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3875 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3876 see whether CreateFile failed.
3878 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3880 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3881 to avoid similar races.
3882 * keyboard.c (pending_signals): Now bool, not int.
3884 Port timers to OpenBSD, plus check for timer failures.
3885 OpenBSD problem reported by Han Boetes.
3886 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3888 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3889 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3890 like OpenBSD, which has timer_settime but does not declare it.
3891 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3892 whether to use itimerspec-related primitives. All uses of
3893 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3895 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3897 * profiler.c (handle_profiler_signal): Fix a malloc race
3898 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3900 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3902 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3904 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3906 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3907 consistent with the change in return value of 'safe_strsignal'.
3909 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3911 Prefer plain 'static' to 'static inline' (Bug#12541).
3912 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3913 (bidi_set_sor_type, bidi_push_embedding_level)
3914 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

3919 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3920 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3921 Now 'static', not 'static inline'.
3923 Count overruns when profiling; change units to ns.
3924 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3925 Give extra weight to samples after overruns, to attempt to count
3926 the time more accurately.
3927 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3928 the underlying primitives nominally do ns.
3929 (Fprofiler_cpu_start): Document the change. Mention that
3930 the sampling intervals are only approximate.
3932 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3934 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3936 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3937 case for the special 0 coding-system.
3939 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3940 (Fmake_overlay): Remove redundant tests.
3941 (fix_start_end_in_overlays): Remove redundant recentering.
3943 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3945 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3946 Update dependencies.
3948 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3950 Fix a malloc race condition involving strsignal.
3951 A signal can arrive in the middle of a malloc, and Emacs's signal
3952 handler can invoke strsignal, which can invoke malloc, which is
3953 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3954 Fix it by altering the signal handler so that it does not invoke
3956 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3957 * process.c (status_message): Use const pointer, in case strsignal
3958 is #defined to safe_strsignal.
3959 * sysdep.c (sys_siglist, init_signals): Always define and
3960 initialize a substitute sys_siglist if the system does not define
3961 one, even if HAVE_STRSIGNAL.
3962 (safe_strsignal): Rename from strsignal. Always define,
3963 using sys_siglist. Return a const pointer.
3964 * syssignal.h (safe_strsignal): New decl.
3965 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3967 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3969 * w32proc.c (timer_loop): Fix code that waits for timer
3970 expiration, to avoid high CPU usage.
3972 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3974 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3975 (sweep_weak_table): Remove redundant prototypes.
3977 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3979 * emacs.c: Move the inclusion of TERM_HEADER after including
3980 windows.h on WINDOWSNT. This avoids compilation problems with
3983 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3985 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3986 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3987 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3988 as the previous version used 'void *'.
3990 * ralloc.c (ROUNDUP): Fix last change.
3991 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3994 * w32proc.c <disable_itimers>: New static flag.
3995 (init_timers): Initialize it to zero, after creating the critical
3996 sections used by the timer threads.
3997 (term_timers): Set to 1 before deleting the critical sections.
3998 (getitimer, setitimer): If disable_itimers is non-zero, return an
3999 error indication without doing anything. Reported by Fabrice
4000 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4001 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4003 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4006 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4007 term_ntproc after all the other bookkeeping, to get timers working
4008 as long as possible.
4010 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4012 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4013 Suggested by Juri Linkov in
4014 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4016 Prefer plain 'static' to 'static inline' (Bug#12541).
4017 With static functions, modern compilers inline pretty well by
4018 themselves; advice from programmers often hurts as much as it helps.
4019 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4020 this change shrinks the text size of the Emacs executable by 1.1%
4021 without affecting CPU significantly in my benchmark.
4022 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4023 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4098 Now 'static', not 'static inline'.
4101 (bidi_copy_it): Do the whole copy with a single memcpy.
4102 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4104 Revert the FOLLOW-SYMLINKS change for file-attributes.
4105 Doing it right would require several changes to Tramp, and there's
4106 not enough time to get that tested before the freeze today.
4107 * dired.c (directory_files_internal, Ffile_attributes):
4110 * frame.c (x_report_frame_params): Port better to wider ints.
4111 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4112 or that pointers can be printed in 15 decimal digits.
4113 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4294 Suggested by Eli Zaretskii in
4295 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
4297 2012-09-30 Eli Zaretskii <eliz@gnu.org>
4299 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
4300 HAVE_TIMER_SETTIME is defined.
4302 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
4304 Profiler improvements: more-accurate timers, overflow checks.
4305 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4306 signal.h, setjmp.h. Include systime.h instead.
4307 (saturated_add): New function.

4314 All uses changed to store the new value.
4315 (handle_profiler_signal): Rename from sigprof_handler_1,
4316 for consistency with other handlers. Do not check whether
4317 cpu_log is a hash-table if garbage collecting, since it
4318 doesn't matter in that case.

4320 for consistency with other handlers.
4321 (setup_cpu_timer): New function, with much of what used to be in
4322 Fprofiler_cpu_start. Check for out-of-range argument.
4323 Prefer timer_settime if available, and prefer
4324 thread cputime clocks, then process cputime clocks, then
4325 monotonic clocks, to the old realtime clock. Use make_timeval
4326 to round more-correctly when falling back to setitimer.
4327 (Fprofiler_cpu_start): Use it.
4328 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4329 Don't assume that passing NULL as the 2nd argument of setitimer

4332 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4333 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4334 non-fatal signal handlers. Ignore SIGPROF on startup.
4335 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4336 in profiler.c, since sysdep.c now uses it.
4338 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4393 * charset.c, charset.h (maybe_unify_char): Now static.
4394 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4395 Since this stuff is now private to charset.c, there's no need for
4396 a public macro and no need to inline by hand.

4468 (sigaction): Rewrite to call sys_signal instead of duplicating its
4470 (sys_kill): Improve commentary.
4472 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4473 consistency with a signature of a signal handler. All callers
4475 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4476 install term_ntproc as a signal handler for SIGABRT, as that
4477 should be done by the dumped Emacs.
4479 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4481 * w32select.c (term_w32select): Protect against repeated
4482 invocation by setting clipboard_owner to NULL after calling

4600 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4601 fatal_error_backtrace.
4603 * w32proc.c (sys_kill): Undo last change: don't do anything when
4604 invoked to deliver SIGABRT to our own process. This is now
4605 handled by emacs_raise.
4607 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4609 * w32term.c (w32_read_socket): Remove leftover reference to
4610 interrupt_input_pending.
4612 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4614 Do not use SA_NODEFER.
4615 Problem reported by Dani Moncayo in
4616 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4618 * sysdep.c (emacs_abort): Do not reset signal handler.
4619 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4620 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4621 wanted even on POSIXish hosts, and it doesn't work on Windows.
4623 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4625 * xterm.c (x_term_init): Call fixup_locale before and after calling
4626 gtk_init (Bug#12392).
4628 2012-09-23 Chong Yidong <cyd@gnu.org>
4630 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4631 Vdynamic_library_alist.
4633 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4634 (Fgnutls_available_p): Caller changed.
4636 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4637 (Flibxml_parse_xml_region): Likewise.
4639 * dispextern.h (struct image_type): Remove arg from init function.
4641 * image.c (Finit_image_library, lookup_image_type)
4642 (define_image_type): Remove now-unneeded second arg.
4643 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4644 (init_tiff_functions, init_gif_functions, init_svg_functions):
4645 Arglist and w32_delayed_load calling convention changed.
4646 (gs_type): Remove init_gs_functions; there is no such function.
4647 (valid_image_p, make_image): Fix caller to lookup_image_type.
4649 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4651 Simplify and avoid signal-handling races (Bug#12471).
4653 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4654 Avoid recursive loop if there's a fatal error in the function itself.
4655 * atimer.c (pending_atimers):
4656 * blockinput.h: Don't include "atimer.h"; no longer needed.
4657 (interrupt_input_pending): Remove. All uses removed.
4658 pending_signals now counts both atimers and ordinary interrupts.
4659 This is less racy than having three separate pending-signal flags.
4660 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4662 Rename from their upper-case counterparts BLOCK_INPUT,
4663 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4664 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4665 This makes it easier to access volatile variables more accurately.
4666 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4667 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4668 that's more reliable if the code is buggy and sets
4669 interrupt_input_blocked to a negative value. All uses changed.
4670 * atimer.c (deliver_alarm_signal):
4671 Remove. No need to deliver this to the parent; any thread can
4672 handle this signal now. All uses replaced by underlying handler.
4673 * atimer.c (turn_on_atimers):
4674 * dispnew.c (handle_window_change_signal):
4675 * emacs.c (handle_danger_signal):
4676 * keyboard.c (kbd_buffer_get_event):
4677 Don't reestablish signal handler; not needed with sigaction.
4678 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4680 Rework to avoid unnecessary accesses to volatile variables.
4681 (UNBLOCK_INPUT_TO): Now a function.
4682 (totally_unblock_input, unblock_input): New decls.
4683 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4684 (init_data): Remove. Necessary stuff now done in init_signal.
4685 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4686 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4687 (fatal_error_code): Remove; no longer needed.
4688 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4689 it doesn't always backtrace. All uses changed. No need to reset
4690 signal to default, since sigaction and/or die does that for us now.
4691 Use emacs_raise (FOO), not kill (getpid (), FOO).
4692 (main): Check more-accurately whether we're dumping.
4693 Move fatal-error setup to sysdep.c
4694 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4695 * gtkutil.c (xg_get_file_name, xg_get_font):
4696 Remove no-longer-needed signal-mask manipulation.
4697 * keyboard.c, process.c (POLL_FOR_INPUT):
4698 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4699 * keyboard.c (read_avail_input): Remove.
4700 All uses replaced by gobble_input.
4701 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4702 (kbd_buffer_store_event_hold, gobble_input):
4703 (record_asynch_buffer_change) [USABLE_SIGIO]:
4704 (store_user_signal_events):
4705 No need to mess with signal mask.
4706 (gobble_input): If blocking input and there are terminals, simply
4707 set pending_signals to 1 and return. All hooks changed to not
4708 worry about whether input is blocked.
4709 (process_pending_signals): Clear pending_signals before processing
4710 them, in case a signal comes in while we're processing.
4711 By convention callers now test pending_signals before calling us.
4712 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4713 New functions, to support changes to blockinput.h.
4714 (handle_input_available_signal): Now extern.
4715 (reinvoke_input_signal): Remove. All uses replaced by
4717 (quit_count): Now volatile, since a signal handler uses it.
4718 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4719 All callers changed. Block SIGINT only if not already blocked.
4720 Clear sigmask reliably, even if Fsignal returns, which it can.
4721 Omit unnecessary accesses to volatile var.
4722 (quit_throw_to_read_char): No need to restore sigmask.
4723 * keyboard.c (gobble_input, handle_user_signal):
4724 * process.c (wait_reading_process_output):
4725 Call signal-handling code rather than killing ourselves.
4726 * lisp.h: Include <float.h>, for...
4727 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4728 (pending_signals): Now volatile.
4729 (syms_of_data): Now const if IEEE floating point.
4730 (handle_input_available_signal) [USABLE_SIGIO]:
4731 (terminate_due_to_signal, record_child_status_change): New decls.
4732 * process.c (create_process): Avoid disaster if memory is exhausted
4733 while we're processing a vfork, by tightening the critical section
4735 (send_process_frame, process_sent_to, handle_pipe_signal)
4736 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4738 (send_process): No need for setjmp/longjmp any more, since the
4739 SIGPIPE stuff is now gone. Instead, report an error if errno
4741 (record_child_status_change): Now extern. PID and W are now args.
4742 Return void, not bool. All callers changed.
4743 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4744 Remove. All uses removed. This bug should be fixed now in a
4746 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4747 and record the child status change directly. This avoids the
4748 need to futz with the signal mask.
4749 (process_fatal_action): Move here from emacs.c.
4750 (emacs_sigaction_flags): New function, containing
4751 much of what used to be in emacs_sigaction_init.
4752 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4753 caught by emacs, to make races less likely.
4754 (deliver_process_signal): Rename from handle_on_main_thread.
4756 (BACKTRACE_LIMIT_MAX): Now at top level.
4757 (thread_backtrace_buffer, threadback_backtrace_pointers):
4759 (deliver_thread_signal, deliver_fatal_thread_signal):
4760 New functions, for more-accurate delivery of thread-specific signals.
4761 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4762 (deliver_arith_signal): Handle in this thread, not
4763 in the main thread, since it's triggered by this thread.
4764 (maybe_fatal_sig): New function.
4765 (init_signals): New arg DUMPING so that we can be more accurate
4766 about whether we're dumping. Caller changed.
4767 Treat thread-specific signals differently from process-general signals.
4768 Block all signals while handling fatal error; that's safer.
4769 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4771 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4772 Ignore SIGPIPE unless batch.
4773 (emacs_backtrace): Output backtrace for the appropriate thread,
4774 which is not necessarily the main thread.
4775 * syssignal.h: Include <stdbool.h>.
4776 (emacs_raise): New macro.
4777 * xterm.c (x_connection_signal): Remove; no longer needed
4778 now that we use sigaction.
4779 (x_connection_closed): No need to mess with sigmask now.
4780 (x_initialize): No need to reset SIGPIPE handler here, since
4781 init_signals does this for us now.
4783 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4785 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4786 background rect may be larger (Bug#12245).
4788 2012-09-23 Chong Yidong <cyd@gnu.org>
4790 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4792 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4794 * .gdbinit: Just stop at fatal_error_backtrace.
4795 See Stefan Monnier's request in
4796 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4797 Remove no-longer-used query of system type.
4799 2012-09-22 Chong Yidong <cyd@gnu.org>
4801 * search.c (Freplace_match): Doc fix (Bug#12325).
4803 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4805 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4806 (Fline_end_position): Doc fix.
4808 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4810 2012-09-22 Chong Yidong <cyd@gnu.org>
4812 * dispextern.h (struct image_type): Add new slot, storing a type
4813 initialization function.
4815 * image.c (define_image_type): Call the image initializer function
4816 if it is defined. Arguments and return value changed.
4817 (valid_image_p, make_image): Callers changed.
4818 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4819 (gif_type, imagemagick_type, svg_type, gs_type):
4820 Add initialization functions.
4821 (Finit_image_library): Call lookup_image_type.
4822 (CHECK_LIB_AVAILABLE): Macro deleted.
4823 (lookup_image_type): Call define_image_type here, rather than via
4824 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4825 (syms_of_image): Move define_image_type calls for xbm_type and
4826 pbm_type to lookup_image_type.
4828 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4830 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4831 'idle_timers' from here ...
4832 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4833 lists, to avoid infloops when the timer does something stupid,
4834 like reinvoke itself with the same or smaller time-out.
4837 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4839 * window.c (Fsplit_window_internal): Handle only Qt value of
4840 Vwindow_combination_limit separately.
4841 (Qtemp_buffer_resize): New symbol.
4842 (Vwindow_combination_limit): New default value.
4845 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4847 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4848 the new overlay string. (Bug#10159)
4850 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4852 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4853 or that fprintf is async-signal-safe. POSIX doesn't require
4856 2012-09-22 Chong Yidong <cyd@gnu.org>
4858 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4861 2012-09-22 Kenichi Handa <handa@gnu.org>
4863 * composite.c (composition_reseat_it): Handle the case that a
4864 grapheme cluster is not covered by a single font (Bug#12352).
4866 2012-09-21 Chong Yidong <cyd@gnu.org>
4868 * image.c (define_image_type): Avoid adding duplicate types to
4869 image_types (Bug#12463). Suggested by Jörg Walter.
4871 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4873 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4874 (print_load_command_name): Add case LC_DATA_IN_CODE.
4875 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4877 2012-09-21 Glenn Morris <rgm@gnu.org>
4879 * eval.c (Frun_hook_with_args_until_success)
4880 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4882 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4884 * fileio.c (Ffile_selinux_context): Only call freecon when
4885 lgetfilecon succeeded.
4886 (Fset_file_selinux_context): Likewise. (Bug#12444)
4888 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4890 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4891 reordering, locate the cursor by calling set_cursor_from_row; if
4892 that fails, clear the desired glyph matrix before returning a
4893 failure indication to the caller. Fixes leaving garbled display
4894 when fast scrolling with a down-key. (Bug#12403)
4895 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4896 scrolling through multibyte text.
4898 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4900 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4901 calling mark_vectorlike since that's the one that marks the window.
4902 (mark_discard_killed_buffers): Mark the final cdr.
4903 * window.h (struct window): Move prev/next_buffers to the
4904 non-standard fields.
4905 * window.c (make_window): Initialize prev/next_buffers manually.
4907 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4909 Omit unused arg EXPECTED from socket hooks.
4910 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4911 * nsterm.m (ns_term_init):
4912 * termhooks.h (struct terminal.read_socket_hook):
4913 * w32inevt.c (w32_console_read_socket):
4914 * w32term.c (w32_read_socket):
4915 * xterm.c (XTread_socket):
4916 Omit unused arg EXPECTED. All callers changed.
4917 (store_user_signal_events): Return void, not int, since callers no
4918 longer care about the return value. All uses changed.
4920 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4922 * w32gui.h (XParseGeometry): Do not declare.
4924 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4926 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4927 Ignore 'expected'. See Eli Zaretskii in
4928 <http://bugs.gnu.org/12471#8> (last line).
4930 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4931 (XParseGeometry): Now static. Substitute extremal values for
4932 values that are out of range.
4934 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4936 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4938 * nsfns.m (XParseGeometry): Remove.
4939 (Fx_create_frame): Call x_set_offset to correctly interpret
4940 top_pos in geometry.
4942 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4943 (Fx_parse_geometry): If there is a space in string, call
4944 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4946 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4948 * search.c (scan_buffer): Use character positions in calls to
4949 region_cache_forward and region_cache_backward, not byte
4950 positions. (Bug#12196)
4952 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4953 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4955 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4956 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4957 emacs_blocked_malloc, now deleted.
4959 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4961 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4962 The workaround was for improving performance on Solaris 2.4, but
4963 is getting in the way now. Emacs will still work if someone is
4964 still running Solaris 2.4 in a museum somewhere; Sun dropped
4965 support for Solaris 2.4 in 2003.
4966 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4967 * process.c (create_process) [HAVE_WORKING_VFORK]:
4968 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4969 since Emacs no longer uses vfork on that platform.
4971 2012-09-17 Glenn Morris <rgm@gnu.org>
4973 * emacs.c: Use COPYRIGHT.
4975 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4977 Remove configure's --without-sync-input option (Bug#12450).
4978 When auditing signal-handling in preparation for cleaning it up,
4979 I found that SYNC_INPUT has race conditions and would be a real
4980 pain to fix. Since it's an undocumented and deprecated
4981 configure-time option, now seems like a good time to remove it.
4982 Also see <http://bugs.gnu.org/11080#16>.
4983 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4984 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4985 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4986 (malloc_hysteresis):
4987 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4988 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4989 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4990 (dont_register_blocks, bytes_used_when_reconsidered)
4991 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4992 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4993 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4994 Remove. All uses removed.
4995 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4996 implementation, one that depends on whether the new macro
4997 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4999 * atimer.c (run_timers, handle_alarm_signal):
5000 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5001 (handle_async_input, process_pending_signals)
5002 (handle_input_available_signal, init_keyboard):
5003 * nsterm.m (ns_read_socket):

5008 * xterm.c (XTread_socket):
5010 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5011 * eval.c (handling_signal): Remove. All uses removed.
5012 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5013 All uses replaced with the SYNC_INPUT version.
5014 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5016 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5019 * font.c (Ffont_shape_gstring): Remove unused local.
5021 2012-09-16 Glenn Morris <rgm@gnu.org>
5023 * Makefile.in (clean): No longer run nextstep's clean.
5025 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5027 (ns-app): Move here from ns.mk, and simplify.
5028 (clean): Simplify nextstep entry.
5029 * ns.mk: Remove file.
5031 2012-09-17 Kenichi Handa <handa@gnu.org>
5033 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5034 not covert the last few charactes.
5036 2012-09-16 Kenichi Handa <handa@gnu.org>
5038 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5039 here, but just check the validity of glyphs in the glyph-string.
5041 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5043 * window.c (Fwindow_parameter, Fset_window_parameter):
5044 Accept any window as argument (Bug#12452).
5046 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5048 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5049 to ns_term_init to avoid memory leak.
5051 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5052 explicit retain/release.
5053 (ns_term_init): Only allow one display. Initialize outerpool and
5056 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5058 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5059 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5060 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5061 the Microsoft problem in a different way, by altering ../nt/config.nt.
5063 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5078 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5079 by lisp.h. This completes removal of setjmp.h inclusion
5080 erroneously announced in the previous commit. (Bug#12446)
5082 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5085 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5086 not defined as a macro. The latter happens on MS-Windows.
5089 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5091 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5092 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5093 Some instances of '#include <setjmp.h>' removed, if the
5094 only reason for the instance was because "lisp.h" was included.
5095 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5096 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5097 and _longjmp with the new symbols. Emacs already uses _setjmp if
5098 available, so this change affects only POSIXish hosts that have
5099 sigsetjmp but not _setjmp, such as some versions of Solaris and
5100 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5101 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5102 (png_load_body) [HAVE_PNG]:
5103 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5104 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5105 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5106 since PNG requires jmp_buf. This is the only exception to the
5107 general rule that we now use sys_setjmp and sys_longjmp.
5108 This exception is OK since this code does not change the signal
5109 mask or longjmp out of a signal handler.
5111 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5113 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5114 Include "syssignal.h", for 'main_thread'.
5116 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5118 Avoid out-of-range marker position (Bug#12426).
5119 * insdel.c (replace_range, replace_range_2):
5120 Adjust markers before overlays, as suggested by comments.
5121 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5122 Remove redundant check before calling offset_intervals.
5124 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5126 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5127 current buffer (Bug#12387).
5129 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5131 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5133 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5135 Use a more backwards-compatible timer format (Bug#12430).
5136 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5137 vector element, not from the 4th, since PSECS is now at the end.
5138 (Fcurrent_idle_time): Doc fix.
5140 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5142 Function to mark objects and remove killed buffers at once.
5143 * alloc.c (discard_killed_buffers): Rename to ...
5144 (mark_discard_killed buffers) ... new name. Add marking
5145 of remaining objects. Fix comment. Adjust users.
5146 (mark_object): Do not touch frame buffer lists here.
5147 * frame.c (delete_frame): Reset frame buffer lists here.
5149 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5151 Better workaround for GNOME bug when --enable-gcc-warnings.
5152 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5153 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5154 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5156 Simplify SIGIO usage (Bug#12408).
5157 The code that dealt with SIGIO was crufty and confusing, e.g., it
5158 played tricks like "#undef SIGIO" but these tricks were not used
5159 consistently. Simplify mostly by not #undeffing standard symbols,
5160 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5161 or not as we please) rather than "defined SIGIO" (standard symbol
5162 that we probably shouldn't #undef).
5163 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5164 Modules that need it can include it.
5165 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5166 * dispextern.h (ignore_sigio): New decl.
5167 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5168 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5169 * emacs.c (shut_down_emacs):
5170 * keyboard.c (kbd_buffer_store_event_hold):
5171 Use ignore_sigio rather than invoking 'signal' directly.
5172 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5174 (FIONREAD, SIGIO): Do not #undef.
5175 (tty_read_avail_input): Use #error rather than a syntax error.
5176 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5177 for I_PIPE, used by SETUP_SLAVE_PTY.
5178 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5179 * sysdep.c (croak): Remove; no longer needed. This bit of
5180 temporary code, with Fred N. Fish's comment that it's temporary,
5181 has been in Emacs since at least 1992!
5182 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5183 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5184 * syssignal.h (croak): Remove decl.
5185 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5186 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5187 now that we're termios-only.
5188 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5189 * term.c (dissociate_if_controlling_tty): Use #error rather than
5192 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5193 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5194 to work around GNOME bug 683906.
5195 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5196 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5197 This works around GCC bug 54561.
5199 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5201 More fixes for 'volatile' and setjmp/longjmp.
5202 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5203 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5204 (png_load_body) [HAVE_PNG]:
5205 (jpeg_load_body) [HAVE_JPEG]:
5206 New function, with most of the old parent function's body.
5207 (png_load) [HAVE_PNG]:
5208 (jpeg_load) [HAVE_JPEG]:
5209 Invoke the new function, to avoid longjmp munging our locals.
5210 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5211 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5212 longjmp is passed 2, as the C standard doesn't guarantee this.
5213 Instead, store the failure code into mgr->failure_code.
5215 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5217 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5218 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5219 (syms_of_keyboard): Remove support for unread-command-char.
5221 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5223 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5224 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5225 violation. (Bug#12426)
5227 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5229 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5231 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5233 * eval.c: Add `inhibit-debugger'.
5234 (Qinhibit_debugger): New symbol.
5235 (call_debugger): Bind it instead of Qdebug_on_error.
5236 (maybe_call_debugger): Test Vinhibit_debugger.
5237 (syms_of_eval): Define inhibit-debugger.
5238 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5239 (syms_of_xdisp): Remove inhibit-debug-on-message.
5241 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5243 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5244 If a nonvolatile local variable is written before a _longjmp to
5245 the frame containing the variable, and is read after the _longjmp,
5246 the value read is indeterminate. Some local variables of type
5247 'struct handler' and 'struct catchtag' are used in this way, so
5248 mark each of their slots as volatile if the slot can be set before
5249 _longjmp and read afterwards.
5250 * lisp.h (struct handler): var and chosen_clause are now volatile.
5251 (struct catchtag): val, next, and pdlcount are now volatile.
5253 * bidi.c (bidi_push_it, bidi_pop_it):
5254 * fns.c (copy_hash_table):
5255 * image.c (define_image_type):
5256 * keyboard.c (kbd_buffer_store_event_hold):
5257 * process.c (Fprocess_send_eof):
5258 * xfaces.c (x_create_gc) [HAVE_NS]:
5259 * xgselect.c (xg_select):
5260 Prefer assignment to memcpy when either will do.
5262 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5263 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5264 time an item is removed. No need to mark this function 'inline';
5265 the compiler knows better than we do.
5267 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5269 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5270 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5271 to change_frame_size (Bug#12388).
5272 (windowDidResize:): Pass YES to updateFrameSize.
5274 * nsterm.h: Add delay parameter to updateFrameSize.
5276 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5278 Discard killed buffers from deleted window and frame objects.
5279 This reduces an amount of references to killed buffers and
5280 helps GC to reclaim them faster.
5281 * alloc.c (discard_killed_buffers): New function.
5282 (mark_object): Use it for deleted windows and frames.
5283 (mark_object): If symbol's value is set up for a killed buffer
5284 or deleted frame, restore its global binding.
5285 * data.c (swap_in_global_binding): Add GC notice.
5286 (swap_in_symval_forwarding): Use convenient set_blv_where.
5287 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5288 * window.h: ... to here.
5290 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5292 Convenient macro to check whether the buffer is live.
5293 * buffer.h (BUFFER_LIVE_P): New macro.
5294 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5295 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5297 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5299 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5300 composition cases (Bug#12364).
5302 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5303 overhang of succeeding glyphs overlapping box cursor.
5305 * w32term.c (x_draw_glyph_string): Likewise.
5307 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5309 Simplify, document, and port floating-point (Bug#12381).
5310 The porting part of this patch fixes bugs on non-IEEE platforms
5311 with frexp, ldexp, logb.
5312 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5314 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5315 support, by removing commented-out code and briefly listing the
5316 C89 functions excluded. The commented-out stuff was confusing
5317 maintenance, e.g., we thought we needed cbrt but it was commented out.
5318 (logb): Remove decl; no longer needed.
5319 (isfinite): New macro, if not already supplied.
5320 (isnan): Don't replace any existing macro.
5321 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5322 are present on all C89 platforms.
5323 (Ffrexp): Do not special-case zero, as frexp does the right thing
5325 (Flogb): Do not use logb, as it doesn't have the desired meaning
5326 on hosts that use non-base-2 floating point. Instead, stick with
5327 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5328 frexp, to avoid getting an unspecified result.
5330 * xdisp.c (Qinhibit_debug_on_message): Now static.
5332 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5334 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5335 NSBezierPath (Bug#12131).
5337 2012-09-10 Chong Yidong <cyd@gnu.org>
5339 * fns.c (Fdelq, Fdelete): Doc fix.
5341 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5343 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5344 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5346 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5348 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5349 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5352 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5354 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5355 left fringe if the window has a left margin. This avoids leaving
5356 traces of the cursor because its leftmost pixel is not drawn over.
5358 * dispnew.c (update_window_line): When the left margin area of a
5359 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5360 that screen line. (Bug#12277)
5362 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5364 Assume C89 or later for math functions (Bug#12381).
5365 This simplifies the code, and makes it a bit smaller and faster,
5366 and (most important) makes it easier to clean up signal handling
5367 since we can stop worring about floating-point exceptions in
5368 library code. That was a problem before C89, but the problem
5369 went away many years ago on all practical Emacs targets.
5370 * data.c, image.c, lread.c, print.c:
5371 Don't include <math.h>; no longer needed.
5372 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5373 might be autoconfigured, as that never happens.
5375 * doprnt.c (DBL_MAX_10_EXP):
5376 * print.c (DBL_DIG):
5377 Remove. C89 or later always defines these.
5378 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5379 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5380 (arith_error, domain_error, domain_error2):
5381 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5382 no longer needed -- we simply return what C returns. All uses removed.
5383 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5385 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5386 Remove. All uses expanded, as these macros are no longer used
5387 more than once and are now more trouble than they're worth.
5388 (Ftan): Use tan, not sin / cos.
5389 (Flogb): Assume C89 frexp.
5390 (fmod_float): Assume C89 fmod.
5391 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5392 (init_floatfns): Remove. All uses removed.
5394 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5396 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5397 compositeToPoint for OSX < 10.6 (Bug#12390).
5399 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5401 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5402 This produces more-accurate results.
5404 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5406 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5407 changes (Bug#12088).
5409 2012-09-08 Chong Yidong <cyd@gnu.org>
5411 * syntax.c (Fstring_to_syntax): Doc fix.
5413 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5415 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5416 in the internal border.
5417 (x_set_window_size): Remove static variables and their usage.
5418 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5419 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5420 Remove fringe/internal border adjustment (Bug#11052).
5421 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5422 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5423 (ns_fix_rect_ibw): Remove.
5424 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5425 (ns_dumpglyphs_box_or_relief): Ditto.
5426 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5428 (ns_dumpglyphs_image): Ditto.
5429 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5431 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5432 their usage. Add fringe_extended_p and its use as in other terms.
5433 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5434 scroll bar was removed.
5435 (updateFrameSize): New function.
5436 (windowDidResize): Move code to updateFrameSize and call it.
5438 * nsterm.h (EmacsView): Add updateFrameSize.
5440 2012-09-07 Chong Yidong <cyd@gnu.org>
5442 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5444 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5446 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5448 More signal-handler cleanup (Bug#12327).
5449 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5450 Problem introduced when merging patches. Noted by Eli Zaretskii in
5451 <http://bugs.gnu.org/12327#67>.
5452 * floatfns.c: Comment fix.
5453 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5454 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5455 and anyway the declaration is harmless even if SIGDANGER is not defined.
5456 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5457 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5458 source files not surprisingly expected syssignal.h to define, or
5459 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5460 Include <sys/ioctl.h>, for FIONREAD.
5461 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5462 This eliminates a problem whereby other files mysteriously had
5463 to include "syssignal.h" before including "systty.h" if they
5464 wanted to use "#ifdef SIGIO".
5466 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5468 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5470 * w32.c (sigemptyset): Empty the set.
5471 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5473 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5475 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5477 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5478 (mark_object): Likewise for frame objects.
5480 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5482 * syssignal.h (handle_on_main_thread): Always declare,
5483 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5484 This ports to platforms without HAVE_PTHREAD.
5486 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5488 Signal-handler cleanup (Bug#12327).
5489 Emacs's signal handlers were written in the old 4.2BSD style with
5490 sigblock and sigmask and so forth, and this led to some
5491 inefficiencies and confusion. Rewrite these to use
5492 pthread_sigmask etc. without copying signal sets around. Also,
5493 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5494 'signal', and instead use functions that do not attempt to take
5495 over the system name space. This patch causes Emacs's text
5496 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5497 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5498 Do not include <signal.h> or "syssignal.h", as these
5499 modules do not use signals.
5500 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5501 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5502 Do not include <signal.h>, as "syssignal.h" does that for us now.
5503 * atimer.c (sigmask_atimers): New function.
5504 (block_atimers, unblock_atimers): New functions,
5505 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5507 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5508 no longer needed here.
5509 * emacs.c (main): Inspect existing signal handler with sigaction,
5510 so that there's no need to block and unblock SIGHUP.
5511 * sysdep.c (struct save_signal): New member 'action', replacing
5512 old member 'handler'.
5513 (save_signal_handlers, restore_signal_handlers):
5514 Use sigaction instead of 'signal' to save and restore.
5515 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5516 New function. All users of 'signal' modified to use set_sighandler
5517 if they're writeonly, and to use sys_signal if they're read+write.
5518 (emacs_sigaction_init, forwarded_signal): New functions.
5519 (sys_signal): Remove. All uses replaced by calls to sigaction
5520 and emacs_sigaction_init, or by direct calls to 'signal'.
5521 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5522 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5523 all uses replaced by pthread_sigmask etc. calls.
5524 * syssignal.h: Include <signal.h>.
5525 (emacs_sigaction_init, forwarded_signal): New decls.
5526 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5527 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5528 (sigmask, sys_sigmask): Remove; no longer needed.
5529 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5530 (sigblock, sigunblock, sigfree):
5531 (sigsetmask) [!defined sigsetmask]:
5532 Remove. All uses replaced by pthread_sigmask.
5533 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5534 no longer need to be replaced, and its typical old uses
5535 are now done via emacs_sigaction_init and sigaction.
5536 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5537 (sys_sigdel): Remove; unused.
5538 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5540 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5542 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5543 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5545 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5547 Explicitly mark buffer_defaults and buffer_local_symbols.
5548 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5549 mark_local_symbols here.
5550 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5551 since special buffers aren't marked here any more.
5552 (allocate_buffer): Chain new buffer with all_buffers here...
5553 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5555 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5556 (syms_of_buffer): Remove staticpro of the above.
5557 (init_buffer_once): Set names for buffer_defaults and
5558 buffer_local_symbols.
5560 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5562 Use bool for booleans in font-related modules.
5563 * font.c (font_intern_prop, font_style_to_value)
5564 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5565 (generate_otf_features, font_check_otf_features, font_check_otf)
5566 (font_match_p, font_list_entities, font_at):
5567 * fontset.c (fontset_id_valid_p, reorder_font_vector
5568 (fontset_find_font, Fset_fontset_font)
5569 (face_suitable_for_char_p) [0]:
5570 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5571 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5572 (m17n_flt_initialized, ftfont_shape_by_flt):
5573 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5574 * nsfont.m (nsfont_draw):
5575 * w32font.c (w32font_draw):
5576 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5577 Use bool for booleans.
5578 * font.h: Adjust to above API changes.
5579 (struct font, struct font_driver, struct font_driver_list):
5580 Use bool for booleans.
5581 (struct font): Remove useless member encoding_type.
5583 * fontset.c, xftfont.c: Omit unnecessary static decls.
5585 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5587 * alloc.c (mark_object): Revert window marking code
5588 since it's unsafe for the Fset_window_configuration.
5590 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5592 Fix race conditions with signal handlers and errno (Bug#12327).
5593 Be more systematic about preserving errno whenever a signal
5594 handler returns, even if it's not in the main thread. Do this by
5595 renaming signal handlers to distinguish between signal delivery
5596 and signal handling. All uses changed.
5597 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5598 * data.c (deliver_arith_signal): Rename from arith_error.
5599 * dispnew.c (deliver_window_change_signal): Rename from
5600 window_change_signal.
5601 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5602 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5603 * keyboard.c (deliver_input_available_signal): Rename from
5604 input_available_signal.
5605 (deliver_user_signal): Rename from handle_user_signal.
5606 (deliver_interrupt_signal): Rename from interrupt_signal.
5607 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5608 (deliver_child_signal): Rename from sigchld_handler.
5609 * atimer.c (handle_alarm_signal):
5610 * data.c (handle_arith_signal):
5611 * dispnew.c (handle_window_change_signal):
5612 * emacs.c (handle_fatal_signal, handle_danger_signal):
5613 * keyboard.c (handle_input_available_signal):
5614 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5615 * process.c (handle_pipe_signal, handle_child_signal):
5616 New functions, with the actual signal-handling code taken from the
5617 original respective signal handlers, sans the sporadic attempts to
5618 preserve errno, since that's now done by handle_on_main_thread.
5619 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5620 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5621 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5623 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5624 Move initialization of main_thread to sysdep.c's init_signals.
5625 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5626 our usage, and simplifies the mainline code.
5627 (record_child_status_change): New static function, as a helper
5628 for handle_child_signal, and with most of the old child handler's
5630 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5631 (handle_child_signal): Use the above.
5632 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5633 Moved here from emacs.c.
5634 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5635 code moved here from emacs.c's main function.
5636 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5637 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5638 This lets callers save and restore errno properly.
5640 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5642 Remove redundant or unused things here and there.
5643 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5644 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5645 * editfns.c (Fcompare_buffer_substrings): Likewise.
5646 * frame.h (struct terminal, struct font_driver_list):
5647 Remove redundant declarations.
5648 * window.h (Qleft, Qright): Likewise.
5650 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5652 Do not mark objects from deleted buffers, windows and frames.
5653 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5654 (mark_object): Likewise for windows and frames.
5656 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5658 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5659 buffer_defaults and buffer_local_symbols as valid objects.
5660 Return special value to denote them.
5662 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5664 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5665 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5666 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5667 (file_name_absolute_p, Fsubstitute_in_file_name):
5668 (check_executable, check_writable, Ffile_accessible_directory_p)
5669 (Fset_file_selinux_context, Fdefault_file_modes)
5670 (Finsert_file_contents, choose_write_coding_system)
5671 (Fwrite_region, build_annotations, a_write, e_write)
5673 * filelock.c (boot_time_initialized, get_boot_time)
5674 (get_boot_time_1, lock_file_1, within_one_second):
5675 * floatfns.c (in_float):
5676 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5677 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5678 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5679 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5680 * window.c (compare_window_configurations):
5681 Use bool for booleans.
5682 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5683 (Fdefault_file_modes): Now mode_t, not int, for modes.
5684 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5685 (internal_delete_file): Now returns void, not a (boolean) int,
5686 since nobody was looking at the return value.
5687 * lisp.h, window.h: Adjust to above API changes.
5689 * xdisp.c (set_message): Simplify and reindent last change.
5691 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5693 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5695 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5697 * eval.c (call_debugger): Make the function non-static so that we
5698 can call it from set_message.
5700 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5701 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5703 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5705 Give more-useful info on a fatal error (Bug#12328).
5706 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5707 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5708 of doing the work ourselves.
5709 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5710 do most of the work.
5711 (fatal_error_backtrace): New function, taken from the guts
5712 of the old fatal_error_signal, but with a new option to output
5714 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5715 info about the signal than just its number.
5716 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5717 * sysdep.c: Include <execinfo.h>
5718 (emacs_backtrace): New function, taken partly from the previous
5719 code of the 'die' function.
5720 (emacs_abort): Call fatal_error_backtrace rather than abort.
5722 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5724 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5725 eager (load-time) macro-expansion.
5726 * lisp.mk (lisp): Add macroexp.
5728 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5730 Simplify redefinition of 'abort' (Bug#12316).
5731 Do not try to redefine the 'abort' function. Instead, redo
5732 the code so that it calls 'emacs_abort' rather than 'abort'.
5733 This removes the need for the NO_ABORT configure-time macro
5734 and makes it easier to change the abort code to do a backtrace.
5735 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5736 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5737 Remove; sysdep.c's emacs_abort now takes its place.
5738 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5739 'abort' changed to use 'emacs_abort'.
5740 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5741 (abort) [!defined abort]: Rename to ...
5742 (emacs_abort): ... new name.
5743 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5744 the place of the old 'abort' in emacs.c.
5745 * w32.c, w32fns.c (abort): Do not #undef.
5746 * w32.c (emacs_abort): Rename from w32_abort.
5748 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5750 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5751 offsets[j].dv, since the y axis of the screen coordinates points
5752 down, while the y axis of the font definition coordinates points
5753 up. This fixes display of Arabic diacritics such as KASRA and
5754 KASRATAN. (Bug#11860)
5756 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5758 Be more systematic about _setjmp vs setjmp.
5759 * alloc.c (test_setjmp, mark_stack):
5760 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5761 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5762 (png_load, my_error_exit, jpeg_load):
5763 * process.c (send_process_trap, send_process):
5764 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5765 The underscored versions are up to 30x faster on some hosts.
5766 Formerly, the code used setjmp+longjmp sometimes and
5767 _setjmp+_longjmp at other times, with no particular reason to
5768 prefer setjmp+longjmp.
5770 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5772 Fix minor problem found by static checking.
5773 * buffer.c (Fdelete_all_overlays): Return nil.
5775 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5777 * buffer.c (Fdelete_all_overlays): New function.
5779 2012-09-03 Chong Yidong <cyd@gnu.org>
5781 * gtkutil.c: Add extern decl for Qxft.
5783 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5785 * emacs.c, eval.c: Use bool for boolean.
5786 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5787 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5788 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5789 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

5792 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5793 (maybe_call_debugger, Fbacktrace):
5794 * process.c (read_process_output, exec_sentinel):
5795 Use bool for booleans.
5796 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5797 All callers changed.
5798 * eval.c (interactive_p): Omit always-true boolean argument
5799 EXCLUDE_SUBRS_P. All callers changed.
5800 * dispextern.h, lisp.h: Reflect above API changes.
5801 * firstfile.c (dummy): Use the address of 'main', whose signature
5802 won't change, instead of the address of 'initialize', whose
5803 signature just changed from int to bool.
5804 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5805 * msdos.c (fatal_error_in_progress): ... from here.
5806 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5808 (redisplay_internal, unwind_redisplay): Simply clear
5809 REDISPLAYING_P when unwinding, instead of saving its previous,
5810 always-false value and then restoring it.
5812 Clean up some extern decls.
5813 Mostly, this hoists extern decls out of .c files and into .h files.
5814 That way, we're more likely to catch errors if the interfaces change.
5815 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5816 declare xg_mark_data.
5817 * dispextern.h (x_frame_parm_handlers):
5819 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5820 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5821 (Qultra_bold, Qoblique, Qitalic):
5822 Move extern decl here from .c file.
5823 * alloc.c (xg_mark_data) [USE_GTK]:
5825 * eval.c (Qlexical_binding):
5826 * fns.c (time) [!HAVE_UNISTD_H]:

5832 * process.c (QCfamily, QCfilter):
5833 * widget.c (free_frame_faces):
5834 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5835 * xfont.c (x_clear_errors):
5836 * xterm.c (x_frame_parm_handlers):
5837 Remove now-redundant extern decls.
5838 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5839 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5841 * xfaces.c: Remove unnecessary static decls.
5842 * xterm.c (updating_frame): Remove decl of nonexistent object.
5844 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5845 when building globals.h, as the objects that are not built on
5846 this host are not needed to compile C files on this host.
5848 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5850 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5852 * frame.h: Add missing prototype for x_wm_set_size_hint.
5854 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5858 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5859 (Fsubstitute_command_keys):

5864 (make_buffer_string, make_buffer_string_both)
5865 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5877 (set_intervals_multibyte_1, set_intervals_multibyte):
5878 * keyboard.c (decode_timer):
5879 Use bool for boolean.
5880 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5881 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5883 2012-09-02 Chong Yidong <cyd@gnu.org>
5885 * keymap.c (push_key_description): Print M-TAB as C-M-i
5888 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5890 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5891 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5892 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5896 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5898 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5900 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5901 more than one grapheme cluster passed to the shaper: compute the
5902 offset adjustment values separately for each cluster. (Bug#11860)
5904 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5905 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5906 about implicit conversions from integer to pointer.
5908 2012-09-01 Daniel Colascione <dancol@dancol.org>
5910 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5911 system used too early.
5913 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5915 Better seed support for (random).
5916 * emacs.c (main): Call init_random.
5917 * fns.c (Frandom): Set the seed from a string argument, if given.
5918 Remove long-obsolete Gentzel cruft.
5919 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
5920 (init_random): New function.
5922 2012-09-01 Daniel Colascione <dancol@dancol.org>

6225 Special MEM_TYPE_SPARE to denote reserved memory.
6226 * alloc.c (enum mem_type): New memory type.
6227 (refill_memory_reserve): Use new type for spare memory.
6228 This prevents live_cons_p and live_string_p from incorrect

6257 (map_sub_char_table):
6258 Use bool for boolean.

6261 * character.h, charset.h: Adjust to match previous changes.
6262 * character.h (char_printable_p): Remove decl of nonexistent function.
6263 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6264 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6265 are all boolean, so make them single-bit bitfields.
6267 * lisp.h (ASET): Remove attempt to detect side effects.
6268 It was meant to be temporary and it often doesn't work,
6269 because when IDX has side effects the behavior of IDX==IDX
6270 is undefined. See Stefan Monnier in
6271 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6273 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6276 (FUNCTIONP): Use it.

6281 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6282 as that's faster and simpler than static storage. Don't bother
6283 with the g_main_context_query overhead if g_main_context_pending
6284 says no events are pending.
6285 (gfds, gfds_size): Remove these static vars.
6286 (xgselect_initialize): Remove; no longer needed.
6287 All uses and decls removed.
6289 * emacs.c (fatal_error_signal_hook): Remove.
6290 All uses removed. This leftover from old code was always 0.

6317 Use bool for booleans, instead of int.
6318 * lisp.h, process.h: Adjust prototypes to match above changes.
6319 * callint.c (Fcall_interactively): Don't assume the mark's
6320 offset fits in 'int'.

6333 Use bool for booleans, instead of int.
6334 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6335 since the 1-or-0 return value is always ignored anyway.
6336 (mmap_initialized_p):
6337 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6338 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6340 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6342 * bidi.c: Use bool for boolean.
6343 This is a bit more readable, and makes the text segment of bidi.o
6344 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6345 Presumably it's faster too.

6381 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6382 Otherwise, the compiler complains about (A?B:C) where B is void
6383 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6384 (fontset_add): Return void, for FONTSET_ADD.
6386 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6388 * alloc.c: Use bool for booleans.
6389 (gc_in_progress, abort_on_gc)
6390 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6391 (dont_register_blocks) [GC_MALLOC_CHECK]:
6392 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6393 (check_string_bytes, make_specified_string, memory_full)
6394 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6395 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6396 (mark_stack, valid_pointer_p, make_pure_string)
6397 (Fgarbage_collect, survives_gc_p, gc_sweep):
6398 Use bool for booleans, instead of int.
6399 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6400 Remove unused local.
6401 * alloc.c (PURE_POINTER_P):
6402 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6403 * editfns.c (Fformat):
6404 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6406 * fns.c (sweep_weak_table):
6407 * lisp.h (suppress_checking, push_message, survives_gc_p)
6408 (make_pure_string, gc_in_progress, abort_on_gc):
6409 * lread.c (readchar, read1):
6410 * print.c (Fprin1_to_string):
6411 * xdisp.c (push_message):
6412 Use bool for booleans affected directly or indirectly by
6415 Make recently-introduced setters macros.
6416 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6417 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6418 (set_fontset_default, set_fontset_fallback): Rename from their
6419 upper-case counterparts, and make them functions rather than macros.
6420 This is more consistent with the other recently-introduced setters.
6421 These don't need to be inline, since they're local.
6423 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6425 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6426 the loop (Bug#12247).
6428 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6430 * lisp.h (vcopy): Use memcpy rather than our own loop.
6431 This fixes a performance regression introduced by the recent
6432 addition of vcopy. This means 'vcopy' will need to be modified
6433 for a copying collector, but that's OK. Also, tighten the
6434 checking in the assertion.
6436 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6438 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6439 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6440 non-base glyph for the width of the base character, according to
6441 what x_draw_composite_glyph_string_foreground expects.
6442 Generate WADJUST value according to composition_gstring_width's
6443 expectations, to produce correct width of the composed character.
6444 Reverse the sign of the DU offset produced by ScriptPlace.
6446 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6448 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6450 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6452 Avoid direct writes to contents member of struct Lisp_Vector.
6453 * lisp.h (vcopy): New function to copy data into vector.
6454 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6455 * fns.c (Ffillarray): Use ASET.
6456 * keyboard.c (timer_check_2): Use AREF and ASET.
6457 (append_tool_bar_item, Frecent_keys): Use vcopy.
6458 * lread.c (read_vector): Use ASET.
6459 * msdos.c (Frecent_doskeys): Use vcopy.
6460 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6461 (Finternal_merge_in_global_face): Use ASET and vcopy.
6462 * xfont.c (xfont_list_pattern): Likewise.
6464 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6466 * window.c (Fwindow_point): For the selected window always return
6467 the position of its buffer's point.
6468 (Fset_window_point): For the selected window always go in its
6469 buffer to the specified position.
6471 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6473 Setter macros for fontsets.
6474 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6475 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6476 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6479 2012-08-20 Glenn Morris <rgm@gnu.org>
6481 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6482 Don't assume that `ln -f' works.
6484 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6486 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6487 and later about non-assignments with no effect. See discussion at
6488 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6491 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6493 Inline setter functions for Lisp_Objects slots of struct specbinding.
6494 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6497 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6499 * window.c (select_window): Always make selected window's buffer
6502 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6504 Use AREF and ASET for docstrings of category tables.
6505 * category.h (CATEGORY_DOCSTRING): Use AREF.
6506 (SET_CATEGORY_DOCSTRING): Use ASET.
6507 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6509 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6511 Inline setter functions for hash table members.
6512 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6513 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6514 (set_hash_key_and_value, set_hash_index, set_hash_next)
6515 (set_hash_hash): New functions.
6516 * charset.c, fns.c: Adjust users.
6518 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6520 Inline getter and setter functions for per-buffer values.
6521 * buffer.h (per_buffer_default, set_per_buffer_default)
6522 (per_buffer_value, set_per_buffer_value): New functions.
6523 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6524 * buffer.c, data.c: Adjust users.
6526 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6528 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6530 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6532 Rely on <config.h> + <unistd.h> to declare 'environ',
6533 as gnulib does this if the system doesn't.
6534 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6535 Remove declaration. MS-Windows declares it on stdlib.h which is
6536 included by conf_post.h.
6537 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6538 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6539 * vm-limit.c: Include <unistd.h>, for 'environ'.
6541 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6542 (start_of_data): Remove decl; mem-limits.h provides it.
6544 * xdisp.c (handle_invisible_prop): Make it a bit faster
6545 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6547 2012-08-19 Chong Yidong <cyd@gnu.org>
6549 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6552 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6554 * .gdbinit: Use call instead of set when calling a function in the
6557 * data.c (set_internal): Don't use set_blv_found.
6558 (Fkill_local_variable): Likewise.
6560 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6562 * nsfont.m (ns_ascii_average_width): Ensure the string
6563 ascii_printable is initialized with a null-terminated character
6564 array. Otherwise, it can contain undesired extra characters.
6566 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6568 port new setting code to Sun C 5.8 2005/10/13
6569 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6570 Return void, not Lisp_Object. Otherwise, the compiler
6571 complains about (A?B:C) where B is void and C is Lisp_Object
6572 when compiling CHAR_TABLE_SET, due to the recent change to
6573 the API of sub_char_table_set_contents.
6575 2012-08-18 Chong Yidong <cyd@gnu.org>
6577 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6578 for the string case (Bug#3874).

6733 The old version was confusing because it used the same name
6734 'parent' for two different things.
6736 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6738 Functions to get and set Lisp_Object fields of buffer-local variables.

6746 * xfaces.c (merge_face_vectors): If the target font specfies a
6747 font spec, make the font's attributes take precedence over
6748 directly-specified attributes.
6749 (merge_face_ref): Recognize :font.
6751 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6753 Do not use memcpy for copying intervals.
6754 * intervals.c (reproduce_interval): New function.

6774 2012-08-16 Paul Eggert <eggert@cs.ucla.edu>
6776 Use ASCII tests for character types.
6777 * category.c, dispnew.c, doprnt.c, editfns.c, syntax.c, term.c:
6779 Don't include <ctype.h>; was not needed.
6780 * charset.c, doc.c, fileio.c, font.c, frame.c, gtkutil.c, image.c:
6781 * sysdep.c, xfaces.c:
6782 Include <c-ctype.h> instead of <ctype.h>.

6795 * nsterm.m (ns_xlfd_to_fontname):
6796 * sysdep.c (system_process_attributes):
6797 * xfaces.c (hash_string_case_insensitive):
6798 Use C-locale tests instead of locale-specific tests for character

7405 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7406 * w32.c (init_environment): Change the default values of many
7407 environment variables in dflt_envvars[] to NULL, to avoid pushing
7408 them into environment when they were not already defined.
7409 Remove the code that deletes site-lisp subdirectories from the default
7410 value of EMACSLOADPATH, as it is no longer needed.
7411 (check_windows_init_file): Now external, not static.
7412 Use Vload_path as is, without adding anything, as this function is now
7413 called when Vload_path is already set up.
7415 * w32.h (check_windows_init_file): Add prototype.
7417 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7424 installation tree, as appropriate.
7426 * callproc.c (init_callproc_1): Call decode_env_path instead of
7427 doing its equivalent by hand.
7428 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
7429 the code that sets Vexec_path run on MS-Windows.
7431 * lread.c (init_lread): Add comments to #ifdef's.
7433 * msdos.c (dos_set_window_size, IT_update_begin)

7445 Remove unnecessary casts involving pointers.
7446 These casts are no longer needed now that we assume C89 or later,

7460 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7461 Remove unnecessary pointer casts.
7462 * alloc.c (record_xmalloc): New function.
7463 * lisp.h (record_xmalloc): New decl.
7464 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7465 more like a function. This is because the pointer cast is not
7466 needed. All uses changed.
7467 * print.c (print_string, print_error_message): Avoid length recalc.
7469 Improve fix for macroexp crash with debugging (Bug#12118).
7470 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7471 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7472 not supposed to be invoked from the garbage collector.
7473 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7474 (gc_aset): New function, which is like ASET but can be
7475 used in the garbage collector.
7476 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7491 headers (most versions of MinGW w32api don't).
7492 (get_security_info, create_symbolic_link)
7493 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

7504 with addition of handling of symlinks and support for 'lstat'.
7505 If possible, get file's attributes and security information by
7506 handle, not by name. Produce S_IFLNK bit for symlinks, when
7507 called from 'lstat'.
7508 (stat, lstat): New functions, call 'stat_worker'.
7509 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7510 symlinks when the underlying filesystem supports them.
7512 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7514 Fix macroexp crash on Windows with debugging (Bug#12118).
7515 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7516 checking subscripts; problem introduced with the recent
7517 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7518 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7519 since it's used in non-static inline functions now.
7521 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7522 Don't assume buffer size fits in 'int'. Remove unused local.

7539 * category.c (CATEGORY_INLINE):
7540 * character.c (CHARACTER_INLINE):
7541 * charset.c (CHARSET_INLINE):
7542 * composite.c (COMPOSITE_INLINE):
7543 * dispnew.c (DISPEXTERN_INLINE):
7544 * sysdep.c (SYSTIME_INLINE):
7545 Define to EXTERN_INLINE, so that the corresponding functions
7546 are compiled into code.
7547 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7548 (INLINE_HEADER_END): New macros.
7549 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7569 hard-coding the path separator.
7571 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7573 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7574 This how ASET and AREF are supposed to work, and makes
7575 it easier to think about future improvements. See
7576 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7577 * charset.h (set_charset_attr): New function.

8069 the fix for 12036 would have avoided some of the problems noted in
8070 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8071 would have been more obvious.

8081 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8082 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8083 not be usable in #if. This simplifies things.
8085 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8087 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8094 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8095 Adjust to changes in lisp.h and emacs.c, by using

8098 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

8105 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8106 (xreload, hook-run, hookpost-run): Remove.
8107 * emacs.c: Include <verify.h>.
8108 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8109 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8111 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8112 (gdb_USE_LSB_TAG): New enum constants.
8113 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8116 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

9005 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9006 Prefer snprintf to strncpy.
9007 * nsterm.m (ns_term_init):
9008 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9009 * nsterm.m (ns_term_init):
9010 Avoid the need for strncpy, by using build_string or
9011 make_unibyte_string directly. Use dtoastr, not snprintf.
9012 * process.c (Fmake_network_process): Diagnose service names that
9013 are too long, rather than silently truncating them or creating

9044 Optimize pure C strings initialization.
9045 * lisp.h (make_pure_string): Fix prototype.
9046 (build_pure_c_string): New function, defined as static inline. This
9047 provides a better opportunity to optimize away calls to strlen when
9048 the function is called with compile-time constant argument.
9049 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9050 argument, adjust users accordingly. Use build_pure_c_string where
9052 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9053 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9054 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9056 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9058 Avoid calls to strlen in miscellaneous functions.
9059 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

9061 * lread.c (openp): Likewise.
9063 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9065 Avoid calls to strlen in path processing functions.
9066 * fileio.c (file_name_as_directory): Add comment. Change to add
9067 srclen argument and return the length of result. Adjust users

9070 swap 1st and 2nd arguments to obey the common convention.
9071 Adjust users accordingly.
9072 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9074 2012-07-10 Glenn Morris <rgm@gnu.org>

9081 * s/gnu.h (DATA_START): Move definitions to configure.
9083 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9084 We include usg5-4-common.h, which defines them both.
9086 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9087 O_RDONLY already includes it).
9089 Stop ns builds setting the EMACSLOADPATH environment variable.
9090 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9091 Now it does not set EMACSLOADPATH, just returns the load-path string.
9092 * nsterm.h: Update accordingly.
9093 * lread.c [HAVE_NS]: Include nsterm.h.
9094 (init_lread) [HAVE_NS]: Use ns_load_path.

9097 2012-07-09 Glenn Morris <rgm@gnu.org>
9099 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9100 since the included bsd-common.h does so.
9102 Stop ns builds setting the EMACSPATH environment variable.
9103 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9104 (ns_init_paths): Do not set EMACSPATH.
9105 * nsterm.h (ns_exec_path): Add it.
9106 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9109 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9111 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9113 * process.c (wait_reading_process_output): 'waitchannels' was unset
9114 when read_kbd || !NILP (wait_for_cell); fix this.
9116 Add GCC-style 'const' attribute to functions that can use it.
9117 * character.h (char_resolve_modifier_mask):
9118 * keyboard.h (make_ctrl_char):
9119 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9128 Add decls with ATTRIBUTE_CONST.
9130 Minor improvements to make_formatted_string.
9131 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9132 where int is good enough, as vsprintf returns an int.
9133 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9135 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9137 Use make_formatted_string to avoid double length calculation.

9162 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9164 Move marker debugging code under MARKER_DEBUG.
9165 * marker.c (MARKER_DEBUG): Move marker debugging code under
9166 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9167 for bootstrap with --enable-checking (~3x slowdown reported
9168 by Juanma Barranquero <lekktu@gmail.com>).
9169 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9171 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9173 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9174 See <http://bugs.gnu.org/11825#29>.
9176 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9178 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9179 has no font, use the frame's font. (Bug#11813)
9180 (display_line): Add commentary about displaying truncation glyphs
9182 (produce_special_glyphs): Move here from term.c.
9184 * term.c (produce_special_glyphs): Move to xdisp.c.
9186 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9189 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9191 * xdisp.c (display_line): Avoid warning about implicit declaration
9194 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9196 * lisp.h: Remove empty conditional.
9198 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9200 * lread.c (load_path_check): Now static.
9202 Fix some minor --with-ns problems found by static checking.
9203 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9204 (x_set_font) [!HAVE_X_WINDOWS]:
9205 * image.c (xpm_load_image) [HAVE_NS]:
9206 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9207 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9208 Remove unused local.
9209 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9210 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9211 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9212 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9213 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9214 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9215 Fix pointer signedness problem.
9216 * xfaces.c (FRAME_X_FONT_TABLE):
9217 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9219 2012-07-07 Glenn Morris <rgm@gnu.org>
9221 * lread.c (load_path_check): New function, split from init_lread.
9222 (init_lread): Reorganize. Motivation:
9223 If EMACSLOADPATH is set, check/warn about that rather than the
9224 defaults, which we are not going to use. Hence we can remove
9225 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9226 Don't warn if site-lisp directories are missing.
9227 If not installed, start from a blank load-path, since
9228 PATH_LOADSEARCH refers to the eventual installation directories.
9230 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9232 Support truncation and continuation glyphs on GUI frames, when
9233 fringes are disabled. (Bug#11832)
9234 * xdisp.c (init_iterator): Get dimensions of truncation and
9235 continuation glyphs even if on GUI frames.
9236 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9237 or both, are absent.
9238 (start_display, move_it_in_display_line_to): Handle the case of a
9239 GUI frame without a fringe to display continuation or truncation
9241 (insert_left_trunc_glyphs): Support GUI frames: make sure
9242 truncation glyphs overwrite enough glyphs from the current line to
9243 have sufficient space in pixels.
9244 (display_line): Support truncation and continuation glyphs on GUI
9245 frames. If some spare pixels are left on the line after inserting
9246 the truncation glyphs, fill that space with a stretch glyph of a
9247 suitably computed width.
9249 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9250 produce_glyphs, to support GUI sessions.
9252 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9254 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9256 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9258 Do not require float-time's arg to fit in time_t (Bug#11825).
9259 This works better on hosts where time_t is unsigned, and where
9260 float-time is applied to the (negative) difference between two times.
9261 * editfns.c (decode_time_components): Last arg is now double *,
9262 not int *, and means to store all the result as a double, without
9263 worrying about whether the seconds part fits in time_t.
9264 All callers changed.
9265 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9266 All callers changed.
9267 (Ffloat_time): Do not fail merely because the specified time falls
9268 outside of time_t range.
9270 2012-07-07 Glenn Morris <rgm@gnu.org>
9272 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9279 Update dependencies.
9281 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9283 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

9287 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9288 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9289 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

9292 * xfont.c (compare_font_names): Redo to omit the need for casts.
9294 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9296 * xfns.c (Fx_change_window_property): Doc fix.
9297 * w32fns.c (Fx_change_window_property): Doc fix.
9299 * w32fns.c (Fx_window_property): Accept the same arguments as the
9300 X Windows version. Doc fix.
9301 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9303 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9304 Eli Zaretskii <eliz@gnu.org>
9306 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9307 Windows-specific code from nt/config.nt moved here.
9308 Obsolete settings removed.
9310 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9312 * process.c: Avoid unnecessary calls to gettime.
9313 (wait_reading_process_output): Don't get the time of day
9314 when gobbling data immediately and not waiting, as there's no need
9315 for it in that case. This removes a FIXME.
9317 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9319 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9320 is defined (Bug#11768).
9322 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9324 Fix marker debugging code.
9325 * marker.c (byte_char_debug_check): Do not perform the check
9326 if buffer is not multibyte.
9327 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9328 Call byte_char_debug_check with correct arguments.
9330 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9332 Compile marker debugging code only if ENABLE_CHECKING is defined.
9333 * marker.c (byte_char_debug_check, count_markers):
9334 Use only if ENABLE_CHECKING is defined.
9335 (byte_debug_flag): Remove.
9336 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9337 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9339 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9341 Avoid code repetition in marker-related functions.
9342 * marker.c (attach_marker): New function.
9343 (Fset_marker, set_marker_restricted, set_marker_both)
9344 (set_marker_restricted_both): Use it.
9345 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9346 Consistently rename charno to charpos.
9347 (marker_position): Add eassert.
9348 (marker_byte_position): Convert to eassert.

9367 * window.c (save_window_save): Likewise.
9369 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9371 Do not use Fdelete_overlay in delete_all_overlays
9372 to avoid redundant calls to unchain_overlay.
9373 * buffer.c (drop_overlay): New function.
9374 (delete_all_overlays, Fdelete_overlay): Use it.
9375 * minibuf.c (get_minibuffer): Fix comment.

9379 Port to OpenBSD 5.1 amd64.
9380 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9381 This is needed for OpenBSD, and should be harmless on all BSD systems.
9382 Also, include <sys/sysctl.h>, as it should be available on all
9383 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9384 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9385 use p_pid member, not kp_proc.pid.
9387 2012-07-06 Glenn Morris <rgm@gnu.org>
9389 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9391 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9393 More xmalloc and related cleanup.

9402 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9404 Omit needless casts involving void * pointers and allocation.
9405 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9406 as the former is more robust if P's type is changed.
9407 Prefer xzalloc to xmalloc + memset 0.
9408 Simplify malloc-or-realloc to realloc.
9409 Don't worry about xmalloc returning a null pointer.
9410 Prefer xstrdup to xmalloc + strcpy.
9411 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9413 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9414 alloca of a constant.

9419 hscroll is larger than the line width. Fixes long and futile
9420 looping inside extend_face_to_end_of_line (on a TTY) producing
9421 glyphs that are not needed and thrown away.
9423 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9425 * marker.c (set_marker_restricted_both): Simplify by using

9451 * xdisp.c (window_hscroll_limited): New function.
9452 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9453 coordinates when window's hscroll is set to insanely large
9456 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9458 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9519 * fileio.c (time_error_value): Check the right error number.
9520 Problem reported by Troels Nielsen in
9521 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9523 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9525 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9526 This should be fixed in a better way; see Eli Zaretskii in
9527 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9528 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9530 * fileio.c (time_error_value): Rename from special_mtime.
9531 The old name's problems were noted by Eli Zaretskii in
9532 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9534 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9535 This variable's comment says Emacs needs at least one GDB-visible
9536 symbol of type enum pvec_type, to work around GDB problems.
9537 The symbol's value doesn't matter.
9539 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9540 that causes compilation to fail on pre-C99 compilers.
9542 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9544 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9547 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9549 * buffer.c (init_buffer_once): Fix initialization of
9550 headers for buffer_defaults and buffer_local_symbols.
9551 Reported by Juanma Barranquero <lekktu@gmail.com>.
9553 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9555 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9556 * lisp.h (enum pvec_type): Use fewer bits.
9557 (PSEUDOVECTOR_SIZE_BITS): New constant.
9558 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9559 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9560 change in pvec_type.
9561 (PSEUDOVECTOR_TYPEP): New macro.
9562 (TYPED_PSEUDOVECTORP): Use it.
9563 * fns.c (internal_equal): Adapt code to extract pvectype.
9564 * emacs.c (gdb_pvec_type): Update type.
9565 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9566 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9567 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9568 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9569 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9570 abusing vector->header.next.nbytes.
9571 (live_vector_p): Use PVEC_TYPE.
9572 (mark_object): Adapt code to extract pvectype. Use switch.
9574 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9576 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9577 Tighten new eassert a bit.
9579 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9581 Fix compilation with --enable-gcc-warnings and -O1
9583 * doprnt.c (doprnt): Change type of tem to int, initialize
9584 to avoid compiler warning. Add eassert.
9585 * search.c (simple_search): Initialize match_byte to avoid
9586 compiler warning. Add eassert.
9588 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9590 Avoid weird behavior with large horizontal scrolls.
9591 Without this change, for example, large hscroll values would
9592 mess up Emacs's display on Fedora 15 x86, presumably due to
9593 overflows in int calculations in the display code.
9594 Also, if buffers had long lines, Emacs would freeze.
9595 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9596 (set_window_hscroll): New function, containing the old guts of
9597 Fset_window_hscroll. Return the clipped value.
9598 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9599 This avoids the need to check against PTRDIFF_MAX.
9601 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9603 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9605 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9607 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9609 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9610 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9611 since GCC 4.4.6 issues a bogus warning for them.
9613 Fix bugs in file timestamp newness comparisons.
9614 * fileio.c (Ffile_newer_than_file_p):
9615 * lread.c (Fload): Use full timestamp resolution of files,
9616 not just the 1-second resolution, so that files that are only
9617 slightly newer still count as newer.
9618 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9619 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9621 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9623 * fileio.c: Improve handling of file time marker. (Bug#11852)
9624 (special_mtime): New function.
9625 (Finsert_file_contents, Fverify_visited_file_modtime):
9626 Use it to set special mtime values consistently.
9628 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9630 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9631 marker for non-existing file. (Bug#11852)
9633 2012-07-03 Glenn Morris <rgm@gnu.org>
9635 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9636 and did not make it into globals.h).
9638 2012-07-03 Tom Tromey <tromey@redhat.com>
9640 * window.c (Fset_window_margins, Fset_window_fringes)
9641 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9642 * textprop.c (Fprevious_property_change): No longer static.
9643 * syntax.c (Fsyntax_table_p): No longer static.

9665 * intervals.h: Remove EXFUNs.
9666 * fontset.h: Remove EXFUN.

9671 * w32term.h: Remove EXFUNs.
9672 * window.h: Remove EXFUNs.
9673 * xsettings.h: Remove EXFUN.
9674 * xterm.h: Remove EXFUN.
9676 2012-07-03 Glenn Morris <rgm@gnu.org>
9678 * lisp.h (Frandom): Make it visible to C.
9679 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9680 buffer for invisible buffers. (Bug#1229)
9682 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9684 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9685 values which aren't power of 2.
9686 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9687 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9690 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9692 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9694 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9696 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9698 * alloc.c (allocate_vector_block): Remove redundant
9699 calls to mallopt if DOUG_LEA_MALLOC is defined.
9700 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9701 avoid calls to mallopt if zero_vector is returned.
9703 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9705 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9706 is enabled, avoid dereferencing NULL current_sblock if
9709 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9711 Cleanup basic buffer management.
9712 * buffer.h (struct buffer): Change layout to use generic vector
9713 marking code. Fix some comments. Change type of 'clip_changed'
9714 to bitfield. Remove unused #ifndef old.
9715 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9716 (GET_OVERLAYS_AT): Fix indentation.
9717 (for_each_per_buffer_object_at): New macro.
9718 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

9721 * alloc.c (allocate_buffer): Adjust to match new layout of
9722 struct buffer. Fix comment.
9723 (mark_overlay): New function.

9725 Lisp area of struct buffer.
9726 (mark_object): Use it. Adjust marking of misc objects
9727 and related comments.
9729 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9731 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9732 wrapper that is not needed because the wrapped code is a no-op (zero
9733 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9734 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9736 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9738 * alloc.c (mark_buffer): Simplify. Remove prototype.
9739 (mark_object): Add comment. Reorganize marking of vector-like
9740 objects. Use CHECK_LIVE for all vector-like objects except buffers
9741 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9742 Avoid redundant calls to mark_vectorlike for bool vectors.
9744 2012-06-30 Glenn Morris <rgm@gnu.org>
9746 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9748 * epaths.in (PATH_SITELOADSEARCH): New.
9749 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9750 This is rather than relying on --enable-locallisppath elements
9751 having "site-lisp" in their names. (Bug#10208#25, 11658)
9753 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9755 * w32proc.c (sys_select): Accept and ignore one more argument.
9757 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9759 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9760 (pselect) [!MS_DOS]: Redirect to sys_select.
9762 * sysdep.c: Don't include dos.h and dosfns.h.
9764 * process.c (sys_select):
9765 * msdos.c (sys_select): Accept one more argument and ignore it.
9767 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9768 adapt data types and code to that.
9771 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9772 which clashes with the gnulib function of the same name.
9774 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9776 * font.c (font_style_to_value, font_style_symbolic)
9777 (font_prop_validate_style): Add type checks for values in
9780 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9782 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9785 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9787 * xdisp.c (try_window_id): Undo last change.
9789 * w32.c (getwd): Adjust commentary about startup_dir.
9790 (init_environment): Always call sys_access, even in non-MSVC
9791 builds. Don't chdir to the directory of the Emacs executable.
9792 This undoes code from 1997 which was justified by the need to
9793 "avoid conflicts when removing and renaming directories". But its
9794 downside was that every relative file name was being interpreted
9795 relative to the directory of the Emacs executable, which can never
9796 be TRT. In particular, it broke sys_access when called with
9797 relative file names.
9798 (sys_access): Map GetLastError to errno.
9800 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9802 * window.h (struct window): Change type of 'fringes_outside_margins'

9804 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9806 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9809 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9811 * gnutls.c (emacs_gnutls_handshake):
9812 Add QUIT to make the loop interruptible.
9814 2012-06-29 Glenn Morris <rgm@gnu.org>
9816 * charset.c (init_charset): Make lack of etc/charsets fatal.
9818 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9820 * editfns.c (region_limit): Fix type mismatch.
9822 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9824 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9825 undefined. Convert from xassert to eassert.
9826 * nsmenu.m: Convert from xassert to eassert.
9827 * nsterm.m: Likewise.
9829 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9831 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9833 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9835 Avoid integer overflow on scroll-left and scroll-right.
9836 * window.c (HSCROLL_MAX): New macro.
9837 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9838 overflow when requested scroll falls outside ptrdiff_t range.
9840 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9842 * window.h (struct window): Change type of 'hscroll',
9843 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9844 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9845 Adjust users accordingly.
9846 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9847 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9848 from EMACS_INT to ptrdiff_t.
9849 (make_window): Omit redundant initialization.
9851 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9853 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9855 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9857 * window.h (struct window): Change type of 'use_time' and
9858 'sequence_number' from Lisp_Object to int.
9859 * frame.c (make_frame): Adjust users accordingly.
9860 * print.c (print_object): Likewise.
9861 * window.c (select_window, Fwindow_use_time, make_parent_window)
9862 (make_window): Likewise.

9867 enabled with --enable-checking=[all,glyphs] configure option.
9868 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9869 adjust comments accordingly.

9920 avoid GCC warning about unused macro.
9922 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9924 * alloc.c (allocate_string): Omit intervals initialization.
9925 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9926 as in make_pure_string and make_pure_c_string.
9928 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9930 * alloc.c (allocate_string): Fix last change.
9932 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9982 * alloc.c: Remove build_string.
9983 * lisp.h: Define build_string as static inline. This provides
9984 a better opportunity to optimize away calls to strlen when the
9985 function is called with compile-time constant argument.
9986 * image.c (imagemagick_error): Convert to build_string.
9987 * w32proc.c (sys_spawnve): Likewise.
9988 * xterm.c (x_term_init): Likewise.
9990 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9992 Use sprintf return value instead of invoking strlen on result.
9993 In the old days this wasn't portable, since some sprintf
9994 implementations returned char *. But they died out years ago and
9995 Emacs already assumes sprintf returns int.
9996 Similarly for float_to_string.
9997 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9998 * ccl.c (ccl_driver):
9999 * character.c (string_escape_byte8):
10000 * data.c (Fnumber_to_string):
10001 * doprnt.c (doprnt):
10002 * print.c (print_object):
10003 * xdisp.c (message_dolog):
10004 * xfns.c (syms_of_xfns):
10005 Use sprintf or float_to_string result to avoid need to call strlen.
10006 * data.c (Fnumber_to_string):
10007 Use make_unibyte_string, since the string must be ASCII.
10008 * lisp.h, print.c (float_to_string): Now returns int length.
10009 * term.c (produce_glyphless_glyph):
10010 Use sprintf result rather than recomputing it.
10012 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10013 * Makefile.in (ALL_CFLAGS):
10014 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10017 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10019 * dispextern.h (xstrcasecmp): Define to library function
10020 strcasecmp if available.
10021 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10023 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10025 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10028 (push_left_right_boundary, push_menu_pane): Likewise.
10029 * msdos.c (dos_rawgetc): Likewise.

10036 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10038 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10039 sprintf already null-terminates its output.
10041 * xfns.c (x_window): Remove redundant cast.
10043 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10045 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10046 `const char *' to `char *' to avoid compiler warning.
10048 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10050 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10051 instead of truncating it to 63 (admittedly a generous limit).
10053 * process.c: Fix spelling and caps in comments.
10055 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10057 * emacs.c (setpgrp): Remove definition, unused.

10067 (SYSTIME_H): Add nt/inc/sys/time.h.
10069 * systime.h [WINDOWSNT]: Include sys/time.h.
10071 * s/ms-w32.h (struct timespec): Definition moved from
10072 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10074 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10103 * sound.c (sound_warning, parse_sound):
10104 Remove unnecessary forward decls.
10106 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10108 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10109 * lisp.h (WAIT_READING_MAX): New macro.
10110 * dispnew.c (Fsleep_for, sit_for):
10111 * keyboard.c (kbd_buffer_get_event):
10112 * process.c (Faccept_process_output):
10113 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10114 This improves on the previous patch, which introduced a bug
10115 when time_t is unsigned and as wide as intmax_t.
10116 See <http://bugs.gnu.org/9000#51>.
10118 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10120 * dispnew.c (sit_for, Fsleep_for):
10121 * keyboard.c (kbd_buffer_get_event):
10122 * process.c (Faccept_process_output): Avoid compiler warnings when
10123 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
10125 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
10127 * makefile.w32-in: Update dependencies.
10129 * w32.c (ltime): Add return type and declare static.
10130 (w32_get_internal_run_time): Remove usused variable `time_100ns'.

10134 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10135 Privately reported by Herbert J. Skuhra.
10136 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10138 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10139 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10141 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10143 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10144 last argument of make_unibyte_string.
10146 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10147 language ID in the event parameters.
10149 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10150 event.code, not the obscure "character set ID".
10152 2012-06-23 Chong Yidong <cyd@gnu.org>
10154 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
10156 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10158 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

10173 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
10174 Privately reported by Herbert J. Skuhra.
10175 [__FreeBSD__]: Remove "*/" typo after "#include".

10177 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10178 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10179 Don't assume EMACS_TIME and struct timeval are the same type.
10181 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10183 Support higher-resolution time stamps (Bug#9000).
10184 The time stamps are only nanosecond-resolution at the C level,
10185 since that's the best that any real-world system supports now.
10186 But they are picosecond-resolution at the Lisp level, as that's
10187 easy, and leaves room for future OS improvements.
10189 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10192 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10193 Don't get current time unless it's needed.
10195 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10196 now provides it if it's absent.
10197 (start_atimer): Port to higher-res time stamps.
10198 Check for time stamp overflow. Don't get current time more
10199 often than is needed.
10201 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10202 Include systime.h, not time.h.
10203 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10205 * dired.c: Include stat-time.h.
10206 (Ffile-attributes): File times now have higher resolution.
10208 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10209 (struct image): Timestamp now has higher resolution.
10211 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10212 has at least microseconds now. All uses removed.
10213 (update_frame, update_single_window, update_window, update_frame_1)
10214 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10215 (duration_to_sec_usec): Remove; no longer needed.
10217 * editfns.c (time_overflow): Now extern.
10218 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10219 (float-time, Fformat_time_string, Fcurrent_time_string)
10220 (Fcurrent_time_zone): Accept and generate higher-resolution
10222 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10223 (decode_time_components, lisp_seconds_argument): New functions.
10224 (make_time): Now static.
10225 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10226 Report an error if the time is invalid, rather than having the caller
10229 * fileio.c: Include <stat-time.h>
10230 (Fcopy_file): Copy higher-resolution time stamps.
10231 Prefer to set the time stamp via a file descriptor if that works.
10232 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10233 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10234 (Fvisited_file_modtime, Fset_visited_file_modtime):
10235 Support higher-resolution time stamps.
10237 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10239 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10241 * image.c (prepare_image_for_display, clear_image_cache)
10242 (lookup_image): Port to higer-resolution time stamps.
10244 * keyboard.c (start_polling, bind_polling_period):
10245 Check for time stamp overflow.
10246 (read_char, kbd_buffer_get_event, timer_start_idle)
10247 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10248 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10249 Port to higher-resolution time stamps. Do not assume time_t is signed.
10250 (decode_timer): New function. Timers are now vectors of length 9,
10251 not 8, to accommodate the picosecond component.
10252 (timer_check_2): Use it.
10254 * nsterm.m (select_timeout, timeval_subtract): Remove.
10255 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10256 as they're a bit more accurate and handle overflow better.
10257 (ns_select): Change prototype to be compatible with pselect.
10258 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10259 * nsterm.h (ns_select): Adjust prototype.
10261 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10262 us-resolution time stamps.
10263 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10265 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10267 * lisp.h (time_overflow): New decl.
10268 (wait_reading_process_output): First arg is now intmax_t, not int,
10269 to accommodate larger waits.
10271 * process.h (struct Lisp_Process.read_output_delay):
10272 Now counts nanoseconds, not microseconds.
10273 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10275 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10276 (wait_reading_process_output):
10277 Port to ns-resolution time stamps.
10278 (Faccept_process_output, wait_reading_process_output):
10279 Check for time stamp overflow. Do not assume time_t is signed.
10280 (select_wrapper): Remove; we now use pselect.
10281 (Fprocess_attributes): Now generates ns-resolution time stamps.
10283 * sysdep.c: Include utimens.h. Don't include utime.h
10284 or worry about struct utimbuf; gnulib does that for us now.
10285 (gettimeofday): Remove; gnulib provides a substitute.
10286 (make_timeval): New function.
10287 (set_file_times): Now sets ns-resolution time stamps.
10288 New arg FD; all uses changed.
10289 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10290 (system_process_attributes):
10291 Now returns ns-resolution time stamp. All uses changed.
10292 Check for time stamp overflow.
10294 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10295 provides a substitute now.
10297 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10298 since it guarantees struct timespec.
10299 (EMACS_TIME): Now struct timespec, so that we can support
10300 ns-resolution time stamps.
10301 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10302 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10303 (EMACS_USECS): Remove.
10304 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10305 so multiply the arg by 1000 before storing it.
10306 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10308 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10309 Port to ns-resolution time stamps.
10310 (EMACS_TIME_NEG_P): Remove; replaced by....
10311 (EMACS_TIME_SIGN): New macro.
10312 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10313 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10314 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10315 (make_timeval, make_lisp_time, decode_time_components): New decls.
10316 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10317 that it mishandled time_t overflow. You can't compare by subtracting!
10318 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10319 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10321 * term.c: Include <sys/time.h>.
10322 (timeval_to_Time): New function, for proper overflow wraparound.
10323 (term_mouse_position, term_mouse_click): Use it.
10325 * undo.c (record_first_change): Support higher-resolution time stamps
10326 in the undo buffer.
10327 (Fprimitive_undo): Use them when restoring time stamps.
10329 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10330 (w32_get_internal_run_time):
10331 Port to higher-resolution Emacs time stamps.
10332 (ltime): Now accepts single 64-bit integer, as that's more convenient
10335 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10337 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10338 for compatibility with pselect. Support ns-resolution time stamps.
10340 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10342 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10343 Check for time stamp overflow, and support ns-resolution time stamps.
10345 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10346 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10347 (timeval_subtract): Remove; no longer needed.
10348 (XTflash, XTring_bell, x_wait_for_event):
10349 Port to ns-resolution time stamps. Don't assume time_t is signed.
10351 2012-06-22 Chong Yidong <cyd@gnu.org>

10355 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10357 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10358 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10359 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10360 staticidx goes up to 1597 out of 1600 = 0x640.)
10362 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10364 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10365 Otherwise, the umask might be mistakenly 0 while handling input signals.
10367 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

10375 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10376 access to `contents' member of Lisp_Vector objects with AREF and ASET
10379 2012-06-19 Chong Yidong <cyd@gnu.org>
10381 * frame.c (delete_frame): When selecting a frame on a different
10382 text terminal, do not alter the terminal's top-frame.
10384 * xdisp.c (format_mode_line_unwind_data): Record the target
10385 frame's selected window and its terminal's top-frame.
10386 (unwind_format_mode_line): Restore them.
10387 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10389 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10390 since tty frames can be explicitly named.
10391 (prepare_menu_bars): Likewise.
10393 * term.c (Ftty_top_frame): New function.
10395 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10397 Port byte-code-meter to modern targets.
10398 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10399 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10400 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10401 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10402 (METER_1, METER_2): Simplify.
10404 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10406 * data.c (Fdefalias): Return `symbol' (bug#11686).
10408 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10410 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10411 gets killed during executing of this function (Bug#11665).
10412 Try to always return Qt when the buffer has been actually killed.
10413 (Vkill_buffer_query_functions): In doc-string say that functions
10414 run by this hook should not change the current buffer.
10416 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10418 Fix recently-introduced process.c problems found by static checking.
10419 * process.c (write_queue_push, write_queue_pop, send_process):
10420 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
10421 (write_queue_pop): Fix pointer signedness problem.
10422 (send_process): Remove unused local.

10635 Use an inline function on all platforms when using the union type,
10636 since this is simpler and 'static inline' can be used portably

10780 * doprnt.c (doprnt): Truncate multibyte char correctly.
10781 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10782 would mishandle a string argument "Xc" if X was a multibyte
10783 character of length 2: it would truncate after X's first byte
10784 rather than including all of X.
10786 2012-06-06 Chong Yidong <cyd@gnu.org>

10835 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10837 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10838 Convert pctcpu and pctmem to Lisp float properly.
10839 Let the compiler fold better, as 100.0/0x8000 is exact.

10843 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10855 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10856 change its type from Lisp_Object to bitfield.
10857 Change type of 'force_start', 'optional_new_start',
10858 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

10865 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10866 Use 'float' consistently, rather than 'float' in most places
10867 and 'double' in a couple of places.
10869 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10871 * xdisp.c (handle_stop): Detect whether we have overlay strings
10872 loaded by testing it->current.overlay_string_index to be
10873 non-negative, instead of checking whether n_overlay_strings is
10874 positive. (Bug#11587)
10876 2012-05-31 Chong Yidong <cyd@gnu.org>
10878 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10880 * doc.c (Fsubstitute_command_keys): Doc fix.
10882 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10884 * search.c (search_buffer): Remove calls to
10885 r_alloc_inhibit_buffer_relocation, as it is now called by
10886 maybe_unify_char, which was the cause of relocation of buffer text
10889 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10891 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10892 for the duration of call to load_charset, to avoid problems with
10893 callers of maybe_unify_char that access buffer text through C
10896 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10897 decrement the inhibition flag, instead of just setting or
10900 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10902 Remove obsolete '#define static' cruft.
10903 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10904 This #undef was "temporary" in 2000; it is no longer needed
10905 now that '#define static' has gone away.
10906 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10907 (gray_bitmap_bits): Remove; no longer needed.
10908 All uses replaced with definiens.
10909 * xterm.c: Include "bitmaps/gray.xbm".
10911 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10913 Clean up __executable_start, monstartup when --enable-profiling.
10914 The following changes affect the code only when profiling.
10915 * dispnew.c (__executable_start): Rename from safe_bcopy.
10916 Define only on platforms that need it.
10917 * emacs.c: Include <sys/gmon.h> when profiling.
10918 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10919 (__executable_start): Remove decl, since lisp.h does it now.
10920 (safe_bcopy): Remove decl; no longer has that name.
10921 (main): Coalesce #if into single bit of code, for simplicity.
10922 Cast pointers to uintptr_t, since standard libraries want integers
10924 * lisp.h (__executable_start): New decl.
10926 2012-05-31 Glenn Morris <rgm@gnu.org>
10928 * image.c (Fimagemagick_types): Doc fix.
10930 2012-05-30 Jim Meyering <meyering@redhat.com>
10932 * callproc.c (Fcall_process_region): Include directory component
10933 in mkstemp error message (Bug#11586).
10935 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10937 * alloc.c, lisp.h (make_pure_vector): Now static.
10939 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10941 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10942 Move to byte-run.el.

10944 * data.c (Fdefalias): Purify definition, except for keymaps.
10945 (Qdefun): Move from eval.c.
10946 * lisp.h (Qdefun): Remove.
10947 * lread.c (read1): Tiny simplification.
10949 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10951 Do not create empty overlays with the evaporate property (Bug#9642).
10952 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10953 Bug#9642, but explicitly check that the buffer the overlay would
10954 be moved to is live and rearrange lines to make sure that errors
10955 will not put the overlay in an inconsistent state.
10956 (Fdelete_overlay): Cosmetics.
10958 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10960 * w32term.c (my_bring_window_to_top): New function.
10961 (x_raise_frame): Use handle returned by DeferWindowPos, which
10962 could be different from the original one.
10963 Call my_bring_window_to_top instead of my_set_foreground_window.

10972 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10974 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10975 This avoids undefined behavior that might cause the eassert
10976 to not catch an out-of-range value.
10978 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10980 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10981 Update dependencies.
10983 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10985 * bidi.c (bidi_mirror_char): Fix last change.
10987 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10989 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10990 when referring to sectname field in printf format.
10992 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10994 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10995 Only r_alloc_inhibit_buffer_relocation needed to be added;
10996 the others were already declared.
10998 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10999 before checking whether it's out of range. Put the check inside
11001 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11003 2012-05-27 Ken Brown <kbrown@cornell.edu>
11005 * callproc.c (Fcall_process): Restore a line that was accidentally
11006 commented out in the 2011-02-13 change (bug#11547).
11008 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11010 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11011 defined on ralloc.c.
11013 * buffer.c [REL_ALLOC]: Remove prototypes of
11014 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11015 they are now on lisp.h.
11017 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11019 * search.c (search_buffer): Use it to inhibit relocation of buffer
11020 text while re_search_2 is doing its job, because re_search_2 is
11021 passed C pointers to buffer text. (Bug#11519)
11023 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11024 Update value to 24.
11026 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11027 state after an additional call to move_it_in_display_line_to, keep
11028 the values of it->max_ascent and it->max_descent found for the
11030 (pos_visible_p): Revert the comparison against bottom_y to what it
11031 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11034 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11036 Fix coding-related core dumps with gcc -ftrapv.
11037 The code was computing A - B, where A and B are pointers, and B is
11038 random garbage. This can lead to core dumps on platforms that
11039 have special pointer registers, and it also leads to core dumps on
11040 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11041 A - B only when B is initialized properly.
11042 * coding.c (coding_set_source, coding_set_destination): Return void.
11043 (coding_change_source, coding_change_destinations): New functions,
11044 with the old behaviors of coding_set_source and coding_set_destination.
11045 All callers that need an offset changed to use these new functions.
11047 2012-05-26 Glenn Morris <rgm@gnu.org>
11049 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11051 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11053 Extend mouse support on W32 text-mode console.
11054 * xdisp.c (draw_row_with_mouse_face):
11055 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11057 * w32console.c: Include window.h.
11058 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11060 (initialize_w32_display): Initialize mouse-highlight data.
11062 * w32inevt.c: Include termchar.h and window.h.
11063 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11064 moves, call note_mouse_highlight. If help_echo changed, call
11065 gen_help_event to produce help-echo message in the echo area.
11066 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11069 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11071 * lread.c (read1): Simplify slightly to avoid an overflow warning
11072 with GCC 4.7.0 on x86-64.
11074 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11076 * bidi.c (bidi_mirror_char): Revert last change: an int is
11077 definitely wide enough here.
11079 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11081 Fix integer width and related bugs (Bug#9874).
11082 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11083 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11084 (string_bytes, check_sblock, allocate_string_data):
11085 (compact_small_strings, Fmake_bool_vector, make_string)
11086 (make_unibyte_string, make_multibyte_string)
11087 (make_string_from_bytes, make_specified_string)
11088 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11089 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11091 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11092 (allocate_pseudovector):
11093 Use int, not EMACS_INT, where int is wide enough.
11094 (inhibit_garbage_collection, Fgarbage_collect):
11095 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11096 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11097 int might not be wide enough.
11098 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11099 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11100 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11101 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11102 (bidi_level_of_next_char, bidi_move_to_visually_next):
11103 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11104 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11105 (Fkill_buffer, Fset_buffer_major_mode)
11106 (advance_to_char_boundary, Fbuffer_swap_text)
11107 (Fset_buffer_multibyte, overlays_at, overlays_in)
11108 (overlay_touches_p, struct sortvec, record_overlay_string)
11109 (overlay_strings, recenter_overlay_lists)
11110 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11111 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11112 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11113 (Foverlay_recenter, last_overlay_modification_hooks_used)
11114 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11115 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11116 (validate_region): Omit unnecessary test for b <= e,
11117 since that's guaranteed by the previous test.
11118 (adjust_overlays_for_delete): Avoid pos + length overflow.
11119 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11120 (report_overlay_modification):
11121 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11122 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11123 Omit pointer cast, which isn't needed anyway, and doesn't work
11124 after the EMACS_INT -> ptrdiff_t change.
11125 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11126 * buffer.h: Adjust decls to match defn changes elsewhere.
11127 (struct buffer_text, struct buffer):
11128 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11129 Use EMACS_INT, not int, where int might not be wide enough.
11130 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11131 not int, to avoid needless 32-bit limit on 64-bit hosts.
11132 (exec_byte_code): Use tighter memory-full test, one that checks
11133 for alloca overflow. Don't compute the address of the object just
11134 before an array, as that's not portable. Use EMACS_INT, not
11135 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11136 * callint.c (Fcall_interactively):
11137 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11138 * callproc.c (call_process_kill, Fcall_process):
11139 Don't assume pid_t fits into an Emacs fixnum.
11140 (call_process_cleanup, Fcall_process, child_setup):
11141 Don't assume pid_t fits into int.
11142 (call_process_cleanup, Fcall_process, delete_temp_file)
11143 (Fcall_process_region):
11144 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11145 (Fcall_process): Simplify handling of volatile integers.
11146 Use int, not EMACS_INT, where int will do.
11147 * casefiddle.c (casify_object, casify_region, operate_on_word)
11148 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11149 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11150 (casify_object): Avoid integer overflow when overallocating buffer.
11151 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11152 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11153 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11154 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11155 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11156 integers are now checked earlier. All uses replaced with XINT.
11158 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11159 For CCL_MapSingle, check that content and value are in int range.
11160 (ccl_driver, Fregister_code_conversion_map):
11161 Check that Vcode_version_map_vector is a vector.
11162 (resolve_symbol_ccl_program): Check that vector header is in range.
11163 Always copy the vector, so that we can check its contents reliably
11164 now rather than having to recheck each instruction as it's being
11165 executed. Check that vector words fit in 'int'.
11166 (ccl_get_compiled_code, Fregister_ccl_program)
11167 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11168 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11169 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11170 contents are in range.
11171 (Fccl_execute_on_string): Check that status is in range.
11172 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11173 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11174 Accept and return EMACS_INT, not int, because callers can pass values
11175 out of 'int' range.
11176 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11177 (multibyte_chars_in_text, parse_str_as_multibyte)

11179 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11180 (string_escape_byte8, Fget_byte):
11181 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11182 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11183 avoid mishandling large integers.
11184 * character.h: Adjust decls to match defn changes elsewhere.
11185 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11186 (Ffind_charset_region):
11187 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11188 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11189 (load_charset_map_from_vector, Fdefine_charset_internal):
11190 Don't assume fixnum fits in int.
11191 (load_charset_map_from_vector, Fmap_charset_chars):
11192 Remove now-unnecessary CHECK_NATNUMs.
11193 (Fdefine_charset_internal): Check ranges here, more carefully.
11194 Don't rely on undefined behavior with signed left shift overflow.
11195 Don't assume unsigned int fits into fixnum, or that fixnum fits
11196 into unsigned int. Don't require max_code to be a valid fixnum;
11197 that's not true for gb10830 4-byte on a 32-bit host. Allow
11198 invalid_code to be a cons, for the same reason. Require code_offset
11199 to be a character. Avoid int overflow if max_char is close
11201 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11202 this is intended anyway and avoids some undefined behavior.
11203 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11204 INDEX_TO_CODE_POINT, as that's what it expects.
11205 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11206 * charset.h (DECODE_CHAR): Return int, not unsigned;
11207 this is what was intended anyway, and it avoids undefined behavior.
11208 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11209 integer-overflow issues.
11210 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11211 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11212 where the argument is EMACS_INT, and this behavior is not intended.
11213 * chartab.c (Fmake_char_table, Fset_char_table_range)
11214 (uniprop_get_decoder, uniprop_get_encoder):
11215 Don't assume fixnum fits in int.
11216 * cmds.c (move_point): New function, that does the gist of
11217 Fforward_char and Fbackward_char, but does so while checking
11218 for integer overflow more accurately.
11219 (Fforward_char, Fbackward_char): Use it.
11220 (Fforward_line, Fend_of_line, internal_self_insert)
11221 (internal_self_insert):
11222 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11223 Fix a FIXME, by checking for integer overflow when calculating
11224 target_clm and actual_clm.

11256 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11257 (consume_chars): Rewrite to not calculate an address outside buffer.
11258 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
11259 Don't access memory outside of the args array.
11260 (Fdefine_coding_system_internal): Check for charset-id overflow.
11261 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
11262 result of ENCODE_CHAR.
11263 * coding.h: Adjust decls to match defn changes elsewhere.
11264 (struct coding_system):
11265 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11948 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11949 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11950 * xterm.c (input_signal_count): Assume volatile works.
11952 2012-05-21 Ken Brown <kbrown@cornell.edu>
11954 * xgselect.c (xg_select): Fix first argument in call to 'select'
11957 2012-05-20 Ken Brown <kbrown@cornell.edu>
11959 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11960 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11962 2012-05-19 Ken Brown <kbrown@cornell.edu>
11964 * xfns.c (x_in_use): Remove `static' qualifier.
11965 * xterm.h (x_in_use): Declare.
11966 * xgselect.c: Include xterm.h.
11967 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11968 and `display_arg' (bug#9754).
11970 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11972 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11974 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11975 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11977 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11979 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11981 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11982 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11984 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11985 reference to image_cache->refcount.
11986 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11988 2012-05-17 Juri Linkov <juri@jurta.org>
11990 * search.c (Fword_search_regexp, Fword_search_backward)
11991 (Fword_search_forward, Fword_search_backward_lax)
11992 (Fword_search_forward_lax): Move functions to isearch.el
11993 (bug#10145, bug#11381).
11995 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11997 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11999 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12001 * lread.c (init_obarray): Declare Qt and Qnil as special.
12003 2012-05-14 Glenn Morris <rgm@gnu.org>
12005 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12006 Put "libexec" before "bin", for the sake of init_callproc_1.
12008 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12010 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12012 * unexaix.c: Port to more-recent AIX compilers.
12013 (report_error, report_error_1, make_hdr, copy_sym)
12014 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12015 Make arguments const char *, not char *, to avoid violations of C
12016 standard and to fix some AIX warnings reported by Gilles Pion.
12018 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12020 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12021 already have overlays loaded.
12022 (handle_single_display_spec): Before returning without displaying
12023 fringe bitmap, synchronize the bidi iterator with the main display
12024 iterator, by calling iterate_out_of_display_property.
12025 (iterate_out_of_display_property): Detect buffer iteration by
12026 testing that it->string is a Lisp string.
12027 (get_next_display_element): When the current object is exhausted,
12028 and there's something on it->stack, call set_iterator_to_next to
12029 proceed with what's on the stack, instead of returning zero.
12030 (set_iterator_to_next): If called at the end of a Lisp string,
12031 proceed to consider_string_end without incrementing string
12032 position. Don't increment display vector index past the end of
12033 the display vector. (Bug#11417)
12034 (pos_visible_p): Don't report a position visible when move_it_to
12035 stopped at the last line of window, which happens to be scanned
12036 backwards by the bidi iteration. (Bug#11464)
12038 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12040 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12041 and right-margin display specs even if the spec is invalid or we
12042 are on a TTY, and thus unable to display on the fringes.
12043 That's because the text with the property will not be displayed anyway,
12044 so we need to signal to the caller that this is a "replacing"
12045 display spec. This fixes display when the spec is invalid or we
12048 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12050 * unexaix.c (make_hdr): Fix typo in prototype.
12051 This bug broke the build on AIX. Problem reported by Gilles Pion.
12053 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12055 * keyboard.c (kbd_buffer_get_event): Read special events also in
12056 batch mode. (Bug#11415)
12058 2012-05-12 Glenn Morris <rgm@gnu.org>
12060 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12062 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12064 * lisp.mk (lisp): Add newcomment.elc.
12066 2012-05-12 Glenn Morris <rgm@gnu.org>
12068 * Makefile.in (MKDIR_P): New, set by configure.
12069 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12071 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12073 Remove unused function hourglass_started.
12074 * dispextern.h (hourglass_started):
12075 * w32fns.c (hourglass_started):
12076 * xdisp.c (hourglass_started): Remove.
12078 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12080 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12081 Update dependencies.
12083 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12085 * xgselect.c (xg_select): Put maxfds+1 into a var.
12086 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12088 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12090 2012-05-10 Dave Abrahams <dave@boostpro.com>
12092 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12093 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12095 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12097 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12098 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12099 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12100 Initialize xd_registered_buses.
12102 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12104 Untag more efficiently if USE_LSB_TAG.
12105 This is based on a proposal by YAMAMOTO Mitsuharu in
12106 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12107 For an admittedly artificial (nth 8000 longlist) benchmark on
12108 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12109 Emacs's overall text size by 1%.
12110 * lisp.h (XUNTAG): New macro.
12111 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12112 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12113 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12114 * eval.c (Fautoload):
12115 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12116 * frame.h (XFRAME): Use XUNTAG.
12118 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12119 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12120 Remove unportable assumptions about print widths of types like
12122 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12123 intptr_t when converting between pointer and integer, to avoid GCC
12124 warnings about wrong width.
12126 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12128 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12129 stack for each reader_thread, instead of defaulting to 8MB
12130 determined by the linker. This avoids failures in creating
12131 subprocesses on Windows 7, see the discussion in this thread:
12132 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12134 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12136 Fix up display of the *Minibuf-0* buffer in the mini window.
12137 * keyboard.c (read_char): Don't clear the echo area if there's no
12139 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12140 contents of *Minibuf-0*) if there's no message displayed in its stead.
12142 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12144 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12147 2012-05-06 Chong Yidong <cyd@gnu.org>
12149 * lisp.mk (lisp): Update.
12151 2012-05-05 Jim Meyering <meyering@redhat.com>
12153 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12155 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12157 * data.c (PUT_ERROR): New macro.
12158 (syms_of_data): Use it. Add new error type `user-error'.
12159 * undo.c (user_error): New function.
12160 (Fprimitive_undo): Use it.
12161 * print.c (print_error_message): Adjust print style for `user-error'.
12162 * keyboard.c (user_error): New function.
12163 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12165 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12167 Do not limit current-time-string to years 1000..9999.
12168 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12169 (Fcurrent_time_string): Support any year that is supported by the
12170 underlying localtime representation. Don't use asctime, as it
12171 has undefined behavior for years outside the range -999..9999.
12173 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12175 Fix race conditions involving setenv, gmtime, localtime, asctime.
12176 Without this fix, interrupts could mess up code that uses these
12177 nonreentrant functions, since setting TZ invalidates existing
12178 tm_zone or tzname values, and since most of these functions return
12179 pointers to static storage.
12180 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12181 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12182 Grow the critical sections to include not just invoking
12183 localtime/gmtime, but also accessing these functions' results
12184 including their tm_zone values if any, and any related TZ setting.
12185 (format_time_string): Last arg is now struct tm *, not struct tm **,
12186 so that the struct tm is saved in the critical section.
12187 All callers changed. Simplify allocation of initial buffer, partly
12188 motivated by the fact that memory allocation needs to be outside
12189 the critical section.
12191 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12193 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12194 with RESET_INTERVAL.
12196 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12197 Remove duplicated buffer name initialization.
12199 2012-05-02 Jim Meyering <jim@meyering.net>
12201 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12203 * xfns.c (x_window): Use xstrdup (Bug#11375).
12205 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12207 * xdisp.c (pos_visible_p): If already at a newline from the
12208 display string before the 'while' loop, don't walk back the glyphs
12209 from it3.glyph_row. Solves assertion violation when the display
12210 string begins with a newline (egg.el). (Bug#11367)
12212 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12214 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12217 2012-05-01 Glenn Morris <rgm@gnu.org>
12219 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12220 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12221 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12222 All were removed before 23.1.
12224 * dispnew.c: Remove HAVE_LIBNCURSES test;
12225 it is always true on relevant platforms.
12227 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12228 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12230 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12232 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12234 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12235 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12238 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12240 Do not avoid creating empty evaporating overlays (Bug#9642).
12241 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12242 That is, do not delete an evaporating overlay if it becomes
12243 empty after its bounds are adjusted to fit within its buffer.
12244 This fix caused other problems, and I'm reverting it until we get
12245 to the bottom of them.
12247 2012-04-27 Chong Yidong <cyd@gnu.org>
12249 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12251 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12253 * xdisp.c (pos_visible_p): If the window start position is beyond
12254 ZV, start the display from buffer beginning. Prevents assertion
12255 violation in init_iterator when the minibuffer window is scrolled
12256 via the scroll bar.
12258 * window.c (window_scroll_pixel_based): Likewise.
12260 2012-04-27 Chong Yidong <cyd@gnu.org>
12262 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12264 2012-04-27 Glenn Morris <rgm@gnu.org>
12266 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12267 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12269 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12271 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12272 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12274 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12276 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12277 display element, check also the underlying string or buffer
12278 character. (Bug#11341)
12280 * w32menu.c: Include w32heap.h.
12281 (add_menu_item): If the call to AppendMenuW (via
12282 unicode_append_menu) fails, disable Unicode menus only if we are
12283 running on Windows 9X/Me.
12285 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12287 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12288 (xgetint): Add missing shift for LSB tags.
12290 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12292 * keyboard.c (read_char): Don't wipe echo area for select window
12293 events: These might get delayed via `mouse-autoselect-window'
12296 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12298 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12299 manipulation of :loaded-from data.
12301 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12303 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12304 now a cons (bug#11311).
12306 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12308 Do not create empty overlays with the evaporate property (Bug#9642).
12309 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12310 if it becomes empty after its bounds are adjusted to fit within
12311 its buffer. Without this fix, in a nonempty buffer (let ((o
12312 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12313 yields an empty overlay that has the evaporate property, which is
12314 not supposed to happen.
12316 Fix minor GTK3 problems found by static checking.
12317 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12318 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12319 (struct _EmacsFixedClass, emacs_fixed_get_type):
12320 Move decls here from emacsgtkfixed.h, since they needn't be public.
12321 (emacs_fixed_get_type): Now static.
12322 (emacs_fixed_class_init): Omit unused local.
12323 (emacs_fixed_child_type): Remove; unused.
12324 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12325 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12326 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12327 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12328 (EMACS_FIXED_GET_CLASS): Remove; unused.
12329 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12331 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12332 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12334 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12336 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12337 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12338 (__malloc_size_t, __malloc_ptrdiff_t):
12339 Remove. All uses removed, replaced by the definiens if needed,
12340 since we can assume C89 or better now.
12341 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
12342 (protect_malloc_state, align, get_contiguous_space)
12343 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

12347 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
12348 (special_realloc, _realloc_internal_nolock, _realloc_internal)
12349 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12350 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12351 Define using prototypes, not old style.
12352 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
12353 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
12354 (align): Don't assume that signed integer overflow wraps around.
12355 Omit unused local var.
12356 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
12357 (_free_internal_nolock, memalign, mallochook, reallochook):
12358 Omit no-longer-needed casts.
12359 (valloc): Use getpagesize, not __getpagesize.
12360 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
12361 (struct hdr): The 'magic' member is now size_t, not unsigned long.
12363 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
12365 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
12367 Move functions from C to Lisp. Make non-blocking method calls
12368 the default. Implement further D-Bus standard interfaces.
12370 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
12371 (QCdbus_request_name_allow_replacement)
12372 (QCdbus_request_name_replace_existing)
12373 (QCdbus_request_name_do_not_queue)

12379 (QCdbus_registered_signal): New Lisp objects.
12380 (XD_DEBUG_MESSAGE): Use sizeof.

12383 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)
12384 (XD_DBUS_VALIDATE_INTERFACE, XD_DBUS_VALIDATE_MEMBER): New macros.
12385 (XD_CHECK_DBUS_SERIAL): Rename from CHECK_DBUS_SERIAL_GET_SERIAL.

12427 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
12429 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12431 * sysdep.c [__FreeBSD__]: Minor cleanups.
12432 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12433 Use Emacs indenting style more consistently. Avoid some casts.

12438 * sysdep.c (list_system_processes, system_process_attributes):
12439 Add implementation for FreeBSD (Bug#5243).

12445 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12447 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12448 It is never used otherwise.
12450 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12452 * print.c (print_preprocess): Only check print_depth if print-circle
12454 (print_object): Check for cycles even when print-circle is nil and
12455 print-gensym is t, but only check print_depth if print-circle is nil.

12459 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12460 set the status to "failed" and ensure that sentinel is run.
12462 2012-04-20 Glenn Morris <rgm@gnu.org>
12464 * process.c (Fset_process_inherit_coding_system_flag)
12465 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12493 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12494 -Wunused-result, -Wunused-variable. This should go away once
12495 the Emacs and Gnulib regex code is merged.
12496 (xmalloc, xrealloc): Now static.
12498 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

12515 New extern decls, to avoid calling undeclared functions.
12516 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12517 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12518 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12519 (NEED_MEM_INSERT): New macro.
12520 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12521 Remove one incorrect comment and fix another.

12535 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12536 Remove decls. This fixes an "It stinks!".
12538 * alloc.c (which_symbols): Fix alignment issue / type clash.
12540 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12542 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12543 (struct Lisp_Misc_Any): Likewise.
12544 (struct Lisp_Free): Likewise.
12545 * alloc.c (union aligned_Lisp_Symbol): Define.

12557 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12558 * s/netbsd.h, s/sol2-6.h:
12559 Remove definition of GC_MARK_STACK, since the default now works.
12560 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12561 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12562 no longer the default.
12563 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12565 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12567 * lread.c (lisp_file_lexically_bound_p):

12584 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12586 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12588 2012-04-11 Daniel Colascione <dancol@dancol.org>
12590 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12591 against is gone. It's better to use vfork now so that when Cygwin
12592 gains a new, working vfork, we use it automatically (bug#10398).
12594 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12596 * window.c (save_window_save): Obey window-point-insertion-type.

12614 * w32.c (w32_delayed_load): Record the full path of the library
12615 being loaded (bug#10424).
12617 2012-04-09 Glenn Morris <rgm@gnu.org>
12619 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12620 not just in the obarray, before snarfing them. (Bug#11036)

12637 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12638 attempts per process (connection).
12640 2012-04-09 Chong Yidong <cyd@gnu.org>
12642 * eval.c (Fuser_variable_p, user_variable_p_eh)
12643 (lisp_indirect_variable): Functions deleted.
12644 (Fdefvar): Caller changed.
12646 * callint.c (Finteractive, Fcall_interactively):
12647 * minibuf.c (Fread_variable): Callers changed.
12649 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12651 * xdisp.c (set_cursor_from_row): If the display string appears in
12652 the buffer at position that is closer to point than the position
12653 after the display string, display the cursor on the first glyph of
12654 the display string. Fixes cursor display when a 'display' text
12655 property immediately follows invisible text. (Bug#11094)
12657 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12659 composite.c: use 'double' consistently
12660 * composite.c (get_composition_id): Use 'double' consistently
12661 instead of converting 'float' to 'double' and vice versa; this is
12662 easier to understand and avoids a GCC warning.
12664 2012-04-09 Glenn Morris <rgm@gnu.org>
12666 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12667 preparation for dumping it with emacs. (Bug#4789)
12668 (leimdir): New variable.

12689 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12690 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12691 objects, as mark_maybe_pointer will catch them otherwise.
12692 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12693 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12705 (GLOBAL_SOURCES): Add xml.c.
12706 ($(BLD)/xml.$(O)): New dependency list.
12708 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12709 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12710 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12711 [!WINDOWSNT]: New macros.
12712 (init_libxml2_functions, libxml2_loaded_p): New functions.
12713 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12714 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12715 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12716 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12718 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12719 Call init_libxml2_functions before calling libxml2 functions.
12720 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12722 * emacs.c: Don't include libxml/parser.h.
12723 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12724 xmlCleanupParser directly.
12726 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12728 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12730 * indent.c (Fvertical_motion): If there is a display string at
12731 point, use it.vpos to compute how many lines to backtrack after
12732 move_it_to point. (Bug#11133)
12734 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12736 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12737 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12738 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12739 macros related to unification of CJK characters. For the details,
12740 see the discussion following the message here:
12741 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12743 2012-04-04 Chong Yidong <cyd@gnu.org>
12745 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12747 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12749 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12750 instead of alloca. (Bug#11138)
12752 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12754 * w32menu.c (is_simple_dialog): Properly check lisp types.
12757 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12759 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12760 position we get to after a call to move_it_to fails the
12761 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12762 only if we wind up in a string from display property. (Bug#11063)
12764 * window.c (Fdelete_other_windows_internal): Invalidate the row
12765 and column information about mouse highlight, so that redisplay
12766 restores it after reallocating the glyph matrices. (Bug#7464)
12768 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12769 string comes from a `display' text property, use the buffer
12770 position of that property as if we actually saw that position in
12772 (move_it_by_lines): Remove the assertion that
12773 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12774 violated when there's a before-string at the beginning of a line.
12777 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12779 * xdisp.c (append_space_for_newline): If the default face was
12780 remapped, use the remapped face for the appended newline.
12781 (extend_face_to_end_of_line): Use the remapped default face for
12782 extending the face to the end of the line.
12783 (display_line): Call extend_face_to_end_of_line when the default
12784 face was remapped. (Bug#11068)
12786 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12788 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12790 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12792 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12794 2012-03-27 Glenn Morris <rgm@gnu.org>
12796 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12799 2012-03-26 Kenichi Handa <handa@m17n.org>
12801 * dispextern.h (struct glyph): Fix previous change. Change the
12802 bit length of glyphless.ch to 25 (Bug#11082).

12806 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12807 (command_loop_1): Use it; inhibit selection update for
12808 handle-select-window too (Bug#8996).
12810 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12812 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12814 2012-03-25 Kenichi Handa <handa@m17n.org>
12816 * dispextern.h (struct glyph): Change the bit length of
12817 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12819 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12821 * s/ms-w32.h (tzname): Include time.h before redirecting to
12822 _tzname. Fixes the MSVC build. (Bug#9960)
12824 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12826 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12829 * xterm.c (XTread_socket): Only modify handling_signal if
12830 !SYNC_INPUT. (Bug#11080)
12832 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12834 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12835 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12836 when fetching a multibyte character consumes more bytes than
12837 CHAR_BYTES returns, due to unification of CJK characters in
12838 string_char. (Bug#11073)

12872 it fit in a valid range (Bug#11003).
12874 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12876 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12877 that is not from display property, accept the row as a "cursor
12878 row" if one of the string's character has a non-nil `cursor'
12879 property. Fixes cursor positioning when there are newlines in
12880 overlay strings, e.g. in icomplete.el. (Bug#11035)
12882 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

12936 push_it before setting up the iterator for the first overlay
12937 string, even if we have an empty string loaded.
12938 (next_overlay_string): If there's an empty string on the iterator
12939 stack, pop the stack. (Bug#10903)
12941 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12943 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12944 Suggested by Stefan Monnier in
12945 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12946 * alloc.c (widen_to_Lisp_Object): New static function.
12947 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12948 and widening them to Lisp_Objects. This would work even if
12949 USE_LSB_TAG is defined and wide integers are used, which might
12950 happen in a future version of Emacs.
12952 2012-02-25 Chong Yidong <cyd@gnu.org>
12954 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12959 before saving to clipboard manager.
12961 2012-02-24 Chong Yidong <cyd@gnu.org>
12963 * keyboard.c (process_special_events): Handle all X selection
12964 requests in kbd_buffer, not just the next one (Bug#8869).
12966 2012-02-23 Chong Yidong <cyd@gnu.org>
12968 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12969 call when setting menu-bar-lines and tool-bar-lines parameters.
12970 (unwind_create_frame_1): New helper function.

12991 when computing $valmask.
12993 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12994 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12995 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12996 It's useless in that case, and it can cause problems on hosts
12997 that allocate halves of EMACS_INT values separately.
12998 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12999 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13000 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13001 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13002 it avoids undefined behavior on hosts where shifting right by more
13003 than the word width has undefined behavior.
13005 2012-02-19 Chong Yidong <cyd@gnu.org>
13007 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13008 (Funhandled_file_name_directory, Ffile_name_as_directory)
13009 (Fdirectory_file_name, Fexpand_file_name)
13010 (Fsubstitute_in_file_name): Protect against invalid file handler
13011 return values (Bug#10845).

13027 2012-02-15 Chong Yidong <cyd@gnu.org>
13029 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13030 marked as special. Also, starting docstrings with * is obsolete.

13045 2012-02-12 Chong Yidong <cyd@gnu.org>
13047 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13048 as that creates a dangerous corner case.
13050 * window.c (Fdelete_window_internal): Invalidate the mouse
13051 highlight (Bug#9904).
13053 2012-02-12 Glenn Morris <rgm@gnu.org>

13058 * nsselect.m (Fx_own_selection_internal)
13059 (Fx_disown_selection_internal, Fx_selection_exists_p)
13060 (Fx_selection_owner_p, Fx_get_selection_internal):
13061 Sync docs and argument specs with the xselect.c versions.
13063 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

13083 2012-02-07 Chong Yidong <cyd@gnu.org>
13085 * buffer.c (Fbuffer_local_variables)
13086 (buffer_lisp_local_variables): Handle unbound vars correctly;
13087 don't let Qunbound leak into Lisp.
13089 2012-02-07 Glenn Morris <rgm@gnu.org>
13091 * image.c (Fimagemagick_types): Doc fix.
13093 * image.c (imagemagick-render-type): Change it from a lisp object
13094 to an integer. Move the doc here from the lisp manual.

13111 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13113 * w32.c (get_emacs_configuration_options):
13114 Include --enable-checking, if specified, in the return value.

13128 Handle overflow when computing char display width (Bug#9496).
13129 * character.c (char_width): Return EMACS_INT, not int.
13130 (char_width, c_string_width): Check for overflow when
13131 computing the width; this is possible now that individual
13132 characters can have unbounded width. Problem introduced
13133 by merge from Emacs 23 on 2012-01-19.

13153 0, do not call append_composite_glyph.
13155 2012-02-02 Kenichi Handa <handa@m17n.org>
13157 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13159 (x_produce_glyphs): If the component of a composition is a null
13160 string, set it->pixel_width to 1 to avoid zero-width glyph.

13164 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13165 first 2 arguments are identical. This makes inserting large
13166 output from a subprocess an order of magnitude faster on
13167 MS-Windows, where all sbrk'ed memory is always contiguous.
13169 2012-01-31 Glenn Morris <rgm@gnu.org>
13171 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13252 2012-01-11 Glenn Morris <rgm@gnu.org>
13254 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
13255 from load-path also when installation-directory is nil. (Bug#10208)
13257 2012-01-10 Glenn Morris <rgm@gnu.org>
13259 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

13262 Update template values to be closer to their typical values these days.
13264 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13266 * xdisp.c (rows_from_pos_range): Accept additional argument
13267 DISP_STRING, and accept any glyph in a row whose object is that
13268 string as eligible for mouse highlight. Fixes mouse highlight of
13269 display strings from overlays. (Bug#10464)
13271 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
13273 emacs: fix an auto-save permissions race condition (Bug#10400)

13275 (Fmake_directory_internal): Use it.
13276 (do_auto_save_make_dir): Set it, instead of invoking chmod after

13280 (Fdo_auto_save): Catch all errors, not just file errors, so
13281 that the var is always cleared.

13782 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13783 Otherwise, valgrind does not work on some platforms.
13784 Problem reported by Andreas Schwab in
13785 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13786 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13787 is set, removing the need for VIRT_ADDRESS_VARIES.
13788 (PURE_P): Use a more-efficient implementation that needs just one
13789 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13790 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13791 to 4 (xorl, subq, cmpq, setbe).
13792 * alloc.c (pure): Always extern now, since that's the
13793 VIRT_ADDR_VARIES behavior.

14253 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14255 * lisp.h (struct Lisp_Symbol): Update comments.
14257 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14259 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14261 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14263 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14264 <oslsachem@gmail.com> for helping to debug this.
14266 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14267 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14268 (g_b_init_get_glyph_outline_w): New static variables.
14269 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14270 (GetGlyphOutlineW_Proc): New typedefs.
14271 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14272 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14274 (w32font_open_internal, compute_metrics):
14275 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14276 instead of calling the "wide" APIs directly.
14278 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14280 * w32.h (syms_of_w32font): Add prototype.
14282 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14284 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14285 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14286 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14287 (Fmove_to_window_line): Doc fix.
14289 2011-10-27 Chong Yidong <cyd@gnu.org>
14291 * process.c (make_process): Set gnutls_state to NULL.
14293 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14294 non-NULL, regardless of GNUTLS_INITSTAGE.
14295 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14296 an error. Set process slots as soon as we allocate them.
14298 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14300 2011-10-27 Chong Yidong <cyd@gnu.org>
14302 * gnutls.c (emacs_gnutls_deinit): New function.
14303 Deallocate credentials structures as well as calling gnutls_deinit.
14304 (Fgnutls_deinit, Fgnutls_boot): Use it.
14306 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14307 (deactivate_process): Call emacs_gnutls_deinit.
14309 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14311 * image.c (x_create_x_image_and_pixmap):
14312 * w32.c (sys_rename, w32_delayed_load):
14313 * w32font.c (fill_in_logfont):
14314 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14316 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14318 * w32fns.c (w32_default_color_map): New function,
14319 extracted from Fw32_default_color_map.
14320 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14322 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14324 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14326 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14328 * keyboard.c (test_undefined): New function (bug#9751).
14329 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14331 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14333 * sysdep.c (init_sys_modes): Fix the check for the controlling
14334 terminal (Bug#6649).
14336 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14338 * dispextern.h (struct bidi_it): New member next_en_type.
14340 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14341 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14342 current character, check also for next_en_type being WEAK_EN.
14343 (bidi_resolve_weak): Don't enter the expensive loop if the current
14344 position is before next_en_pos. Record the bidi type of the first
14345 non-ET, non-BN character we find, in addition to its position.
14346 (bidi_level_of_next_char): Invalidate next_en_type when
14347 next_en_pos is over-stepped.
14349 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14351 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14352 * editfns.c: Rewrite current-time-zone so that it invokes
14353 the equivalent of (format-time-string "%Z") to get the time zone name.
14354 This fixes a bug when the time zone name contains characters that
14355 need converting from the system time locale to Emacs internal format.
14356 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14357 that patch fixed format-time-string to do the conversion, but
14358 I forgot to fix current-time-zone.
14359 (format_time_string): New function, containing most of
14360 what Fformat_time_string used to contain.
14361 (Fformat_time_string): Rewrite in terms of format_time_string.
14362 This doesn't change this function's behavior.
14363 (current-time-zone): Rewrite to use format_time_string.
14364 This fixes the bug reported by Michael Schierl in
14365 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14366 Jason Rumney's 2007-06-07 change worked around this bug, but
14368 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14370 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14372 * xdisp.c (start_display): If the character at POS is displayed
14373 via a display vector, reset IT->current.dpvec_index to zero.
14374 (try_window_reusing_current_matrix): If a line ends in a display
14375 vector or the next line starts in a display vector, continue
14376 redrawing the window even though the character position of
14377 start_row was reached.
14380 2011-10-18 Chong Yidong <cyd@gnu.org>
14382 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14383 with nobreak-char-display too.
14385 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14387 Fix part 3 of bug#9771.
14388 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14389 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14390 non-neutral characters if the current character is a paragraph
14391 separator (a.k.a. Newline). This avoids running the same
14392 expensive loop twice, once when we consume the preceding newline
14393 and the other time when the line actually needs to be displayed.
14394 Avoid the loop when we see neutrals on the base embedding level
14395 following a character whose directionality is the same as the
14396 paragraph's. This avoids running the expensive loop when a line
14397 ends in a long sequence of neutrals, like control characters.
14398 Add assertion against STRONG_AL type. Slightly rearrange code
14399 that determines the type of a neutral given the first non-neutral
14401 (bidi_level_of_next_char): Set next_en_pos to zero when
14402 invalidating its info.
14404 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14406 * xdisp.c (push_display_prop): Determine whether to record string
14407 or buffer position by IT->string, not by IT->method. Allow
14408 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14409 (move_it_vertically_backward): Don't look for character position
14410 immediately after the newline when in a continuation line.
14413 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14415 * window.c (coordinates_in_window): Rewrite and delabelize
14416 vertical border check. (Bug#5357) (Bug#9618)
14418 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14420 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14421 errors in XSetWindowBorder (bug#9310).
14423 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14425 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14426 avoid crash when xmalloc overrun checking is enabled.
14428 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14430 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14431 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14432 cursor motion with <left> and <right> arrow keys.
14434 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14435 some callers set that themselves.
14437 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14439 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14440 display string and the previous row comes from the same string and
14441 is empty. (Bug#9739) (Bug#9738)
14443 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14445 * doc.c (get_doc_string): Encode file name (bug#9735).
14447 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14449 * bidi.c (bidi_level_of_next_char):
14450 * xdisp.c (get_visually_first_element): Remove old incorrect
14451 comments regarding the Unicode Line Separator character.
14453 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14455 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14457 * alloc.c (Fgc_status): Do not access beyond zombies array
14458 boundary if nzombies > MAX_ZOMBIES.
14459 * alloc.c (dump_zombies): Add missing format specifier.
14461 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14463 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14464 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14466 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14467 Some packages use them to denote characters with modifiers.
14469 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14471 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14472 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14473 matching a pp-number. Rename parameter var to var1.
14475 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14477 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14479 2011-10-08 Glenn Morris <rgm@gnu.org>
14481 * callint.c (Fcall_interactively): Give a more explicit error for the
14482 'c' case with a non-character input. (Bug#8479)
14484 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14486 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14488 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14489 lines that are hscrolled on the left.
14491 * dispnew.c (buffer_posn_from_coords): Account for a possible
14492 presence of header-line. (Bug#4426)
14494 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14496 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14497 Don't advertise functionality which we discourage or doesn't work.
14499 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14501 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14502 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14503 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14504 this makes Emacs dump core during garbage collection on rare
14505 occasions. sizeof is obviously inferior to offsetof here, so
14506 stick with offsetof.
14507 (GC_POINTER_ALIGNMENT): New macro.
14508 (mark_memory): Omit 3rd (offset) arg; caller changed.
14509 Don't assume EMACS_INT alignment is the same as pointer alignment.
14511 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14513 * keyboard.c (read_key_sequence_remapped): New var.
14514 (read_key_sequence): Compute remapping in the right buffer.
14515 (command_loop_1): Use read_key_sequence's remapping directly.
14517 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14519 * dired.c (file_name_completion): Don't expand file name.
14520 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14521 before checking file name handler.
14523 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14524 they've been requested explicitly (bug#9591).
14526 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14528 * keymap.c (Fsingle_key_description): Use make_specified_string
14529 instead of build_string to build string from push_key_description.
14532 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14534 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14535 This fixes a Y2038 bug on 64-bit hosts.
14536 * buffer.c (reset_buffer):
14537 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14538 (Fclear_buffer_auto_save_failure):
14539 Use 0, not -1, to represent an unset failure time, since time_t
14540 might not be signed.
14542 Remove dependency on glibc malloc internals.
14543 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14544 Move back here from lisp.h, but with their new implementations.
14545 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14546 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14547 * charset.c (charset_table_init): New static var.
14548 (syms_of_charset): Use it instead of xmalloc. This removes a
14549 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14550 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14551 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14552 Move back to alloc.c.
14553 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14554 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14556 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14558 * nsterm.m (windowDidResize): Call x_set_window_size only when
14559 ns_in_resize is true. Otherwise set pixelwidth/height and
14560 call change_frame_size (Bug#9628).
14562 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14564 Port --enable-checking=all to Fedora 14 x86-64.
14565 * charset.c (syms_of_charset): Also account for glibc malloc's
14566 internal overhead when calculating the initial malloc maximum.
14568 Port --enable-checking=all to Fedora 14 x86.
14569 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14571 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14572 (overrun_check_realloc, overrun_check_free):
14573 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14574 That way, xmalloc returns a properly-aligned pointer even if
14575 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14576 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14577 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14578 into account when calculating the initial malloc maximum.
14579 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14580 Move here from alloc.c, so that charset.c can use it too.
14581 Properly align; the old code wasn't right for common 32-bit hosts
14582 when configured with --enable-checking=all.
14583 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14584 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14586 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14588 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14591 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14593 * xdisp.c (compute_display_string_end): If there's no display
14594 string at CHARPOS, return -1.
14596 * bidi.c (bidi_fetch_char): When compute_display_string_end
14597 returns a negative value, treat the character as a normal
14598 character not covered by a display string. (Bug#9624)
14600 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14602 * lread.c (Fread_from_string): Fix typo in docstring.
14604 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14606 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14607 newline, reseat the iterator instead of bidi-iterating there one
14608 character at a time. (Bug#9610)
14609 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14610 TO_CHARPOS if the bidi iterator is at base embedding level.
14612 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14614 * lread.c (readevalloop): Use correct code for NBSP.
14615 (read1): Likewise. (Bug#9608)
14617 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14619 * dbusbind.c (Fdbus_register_signal): When service is not
14620 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14622 2011-09-25 Glenn Morris <rgm@gnu.org>
14624 * buffer.c (truncate-lines): Doc fix.
14626 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14628 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14629 (Fset_window_next_buffers): Doc fix.
14631 2011-09-24 Glenn Morris <rgm@gnu.org>
14633 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14635 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14637 Fix minor problems found by static checking.
14638 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14639 * indent.c (Fvertical_motion): Fix == vs = typo.
14641 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14643 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14644 Default value is now t. Doc fix.
14646 * indent.c (Fvertical_motion): Compute and apply the overshoot
14647 logic when moving up, not only when moving down. Fix the
14648 confusing name and values of the it_overshoot_expected variable;
14649 logic changes accordingly. (Bug#9254) (Bug#9549)
14651 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14652 CHARPOS is covered by a display string which includes newlines.
14653 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14654 is covered by a display string with embedded newlines.
14656 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14658 * dbusbind.c (Fdbus_register_signal): Add match rule to
14659 Vdbus_registered_objects_table. (Bug#9581)
14660 (Fdbus_register_method, Vdbus_registered_objects_table):
14663 2011-09-24 Jim Meyering <meyering@redhat.com>
14665 do not ignore write error for any output size
14666 The previous change was incomplete.
14667 While it makes emacs --batch detect the vast majority of stdout
14668 write failures, errors were still ignored whenever the output size is
14669 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14670 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14671 && echo FAIL: ignored write error
14672 FAIL: ignored write error
14673 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14674 && echo FAIL: ignored write error
14675 FAIL: ignored write error
14676 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14678 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14680 * emacs.c (Fkill_emacs): In noninteractive mode exit
14681 non-successfully if a write error occurred on stdout. (Bug#9574)
14683 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14685 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14688 * dispextern.h (struct it): Update the comment documenting what
14691 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14693 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14694 a display string, extend search for cursor position to end of row.
14695 (find_row_edges): If the row ends in a newline from a display
14696 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14697 Handle the case of a display string with multiple newlines.
14698 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14699 non-empty line. Fixes confusing cursor motion with arrow keys at
14700 the beginning of a line that starts with whitespace.
14702 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14704 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14707 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14709 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14710 boolean (Bug#9154).
14712 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14714 * xdisp.c (display_line): Record maximum and minimum buffer
14715 positions even if no glyphs were produced (e.g., by a zero-width
14716 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14717 buffer positions that will be removed from the glyph row because
14719 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14720 column is beyond frame width: don't subtract 1 "pixel" when
14721 computing width of the stretch.
14722 (reseat_at_next_visible_line_start): Undo the change made on
14723 2011-09-17 that saved paragraph information and restored it after
14724 the call to `reseat'. (Bug#9545)
14726 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14728 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14729 and turn window cursor on if cleared (Bug#9415).
14731 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14733 * search.c (boyer_moore): Take unibyte characters from pattern
14734 literally. (Bug#9458)
14736 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14738 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14740 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14742 Fix minor problem found by static checking.
14743 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14744 initialized, to pacify gcc -Wuninitialized.
14746 * fileio.c: Report proper errno when syscall falls.
14747 (Finsert_file_contents): Save and restore errno,
14748 so that report_file_error outputs the correct diagnostic.
14749 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14751 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14753 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14755 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14757 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14758 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14760 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14762 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14763 about the current paragraph and restore it after the call to reseat.
14765 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14766 (bidi_find_paragraph_start): Search back for paragraph beginning
14767 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14768 (bidi_move_to_visually_next): Only trigger paragraph-related
14769 computations when the last character is a newline or at EOB, not
14770 just any NEUTRAL_B. (Bug#9470)
14772 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14773 truncated lines if point is covered by a display string. (Bug#9524)
14775 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14777 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14778 (cons_to_x_long): New function.
14779 (lisp_data_to_selection_data): Use it. Correct the test for
14780 short-versus-long data; it was negated. Break out of vector
14781 loop, for efficiency, when a long datum is discovered.
14783 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14785 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14787 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14789 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14790 GCC PR/17406) by declaring this function with external scope.
14792 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14794 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14795 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14797 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14799 * editfns.c (Fformat): Correctly handle text properties on "%%".
14801 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14803 * xterm.c (x_draw_composite_glyph_string_foreground):
14804 * w32term.c (x_draw_composite_glyph_string_foreground):
14805 * term.c (encode_terminal_code):
14806 * composite.c (composition_update_it, get_composition_id):
14807 * xdisp.c (get_next_display_element)
14808 (fill_composite_glyph_string): Add comments about special meaning
14809 of TAB characters in a composition.
14811 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14813 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14814 This occurs when processing a multibyte format.
14815 Problem reported by Wolfgang Jenker.
14817 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14819 * xdisp.c (try_cursor_movement): Only check for exact match if
14820 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14822 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14824 Remove unused external symbols.
14825 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14826 * xdisp.c (calc_pixel_width_or_height): Now static.
14827 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14828 * indent.c (check_display_width):
14829 * w32term.c: Fix comment to match code.
14830 * xterm.c, xterm.h (x_catching_errors): Remove.
14832 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14834 * xselect.c: Use signed conversions more consistently (Bug#9498).
14835 (selection_data_to_lisp_data): Assume incoming selection data are
14836 signed integers, not unsigned. This is to be consistent with
14837 outgoing selection data, which was modified to use signed integers
14838 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14839 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14840 expects long, not unsigned long.
14842 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14844 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14845 computation of loop end. Reported by Johan Bockgård
14848 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14850 * frame.c (Fother_visible_frames_p): Function deleted.
14852 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14854 * indent.c (compute_motion): Process display vector front to back
14855 rather than the other way around. (Bug#2496)
14857 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14859 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14861 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14863 * minibuf.c (Fread_from_minibuffer): Doc fix.
14865 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14867 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14868 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14870 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14872 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14873 value for non-existent files.
14875 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14877 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14878 set its "size" to -1. This will set the modtime_size field of
14879 the corresponding buffer to -1, which is what
14880 verify-visited-file-modtime expects for files that do not exist.
14883 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14885 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14887 * lisp.h: ... from here. push_key_description is no longer
14888 defined in keyboard.c, so its declaration should not be in
14889 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14890 logically belongs with push_key_description.
14892 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14894 * buffer.h: Include <sys/types.h> instead of <time.h>.
14895 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14896 Problem reported by Herbert J. Skuhra.
14898 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14900 * xml.c (parse_region): Make the parsing work for
14901 non-comment-starting XML files again (bug#9144).
14903 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14905 * image.c (gif_load): Fix calculation of bottom and right corner.
14908 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14910 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14911 redisplay in small windows.
14913 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14915 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14917 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14919 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14920 Operate on live windows only.
14922 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14924 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14926 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14928 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14929 only under bidi iteration.
14931 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14933 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14935 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14937 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14938 Without this fix, the command to link temacs failed due to an
14939 undefined symbol __builtin_isnan. This is because
14940 /usr/include/iso/math_c99.h #defines isnan(x) to
14941 __builtin_isnan(x), but the bundled gcc, which identifies itself
14942 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14944 * floatfns.c (isnan): #undef, and then #define to a clone of
14946 (Fisnan): Always define, since it's always available now.
14947 (syms_of_floatfns): Always define isnan at the Lisp level.
14949 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14951 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14953 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14955 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14956 The previous code assumed that file offsets (off_t values) fit in
14957 EMACS_INT variables, which is not true on typical 32-bit hosts.
14958 The code messed up by falsely reporting buffer overflow in cases
14959 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14960 when "big" contains more than 2**29 bytes, even though this
14961 inserts just one byte and does not overflow the buffer.
14962 (Finsert_file_contents): Store file offsets as off_t
14963 values, not as EMACS_INT values. Check for overflow when
14964 converting between EMACS_INT and off_t. When checking for
14965 buffer overflow or for overlap, take the offsets into account.
14966 Don't use EMACS_INT for small values where int suffices.
14967 When checking for overlap, fix a typo: ZV was used where
14968 ZV_BYTE was intended.
14969 (Fwrite_region): Don't assume off_t fits into 'long'.
14970 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14972 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14974 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14976 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14978 sprintf-related integer and memory overflow issues (Bug#9412).
14980 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14981 (esprintf, exprintf, evxprintf): New functions.
14982 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14983 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14984 (modify_event_symbol): Do not assume that the length of
14985 name_alist_or_stem is safe to alloca and fits in int.
14986 (Fexecute_extended_command): Likewise for function name and binding.
14987 (Frecursion_depth): Wrap around reliably on integer overflow.
14988 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14989 since some callers pass EMACS_INT values.
14990 (Fsingle_key_description): Don't crash if symbol name contains more
14991 than MAX_ALLOCA bytes.
14992 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14993 (get_minibuffer): Arg is now EMACS_INT, not int.
14994 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14995 (esprintf, exprintf, evxprintf): New decls.
14996 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14998 * dbusbind.c (signature_cat): New function.
14999 (xd_signature, Fdbus_register_signal):
15000 Do not overrun buffer; instead, report string overflow.
15002 * dispnew.c (add_window_display_history): Don't overrun buffer.
15003 Truncate instead; this is OK since it's just a log.
15005 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15006 even if the time zone offset is outlandishly large.
15007 Don't mishandle offset == INT_MIN.
15009 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15010 when creating daemon; the previous buffer-overflow check was incorrect.
15012 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15013 which has the guts of the old verror function.
15015 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15016 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15018 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15019 (font_unparse_xlfd): Don't blindly alloca long strings.
15020 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15021 fits in int, when using sprintf. Use single snprintf to count
15022 length of string rather than counting it via multiple sprintfs;
15023 that's simpler and more reliable.
15024 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15025 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15026 sprintf, in case result does not fit in int.
15028 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15029 (fontset_from_font): Print it.
15031 * frame.c (tty_frame_count): Now printmax_t, not int.
15032 (make_terminal_frame, set_term_frame_name): Print it.
15033 (x_report_frame_params): In X, window IDs are unsigned long,
15034 not signed long, so print them as unsigned.
15035 (validate_x_resource_name): Check for implausibly long names,
15036 and don't assume name length fits in 'int'.
15037 (x_get_resource_string): Don't blindly alloca invocation name;
15038 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15041 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15042 (xg_check_special_colors, xg_set_geometry):
15043 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15045 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15046 Use esprintf, not sprintf, in case result does not fit in int.
15048 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15049 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15050 it as a large positive number.
15051 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15052 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15054 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15055 in case result does not fit in int.
15057 * print.c (float_to_string): Detect width overflow more reliably.
15058 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15059 buffer overrun. Don't assume list length fits in 'int'. Treat
15060 print length of 0 as 0, not as infinity; to be consistent with other
15061 uses of print length in this function. Don't overflow print length
15062 index. Don't assume hash table size fits in 'long', or that
15063 vectorlike size fits in 'unsigned long'.
15065 * process.c (make_process): Use printmax_t, not int, to format
15066 process-name gensyms.
15068 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15070 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15071 to avoid potential buffer overrun.
15073 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15074 if X resource line is longer than 512 bytes.
15076 * xfns.c (x_window): Make sprintf buffer a bit bigger
15077 to avoid potential buffer overrun.
15079 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15081 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15083 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15085 Integer overflow fixes for scrolling, etc.
15086 Without these, Emacs silently mishandles large integers sometimes.
15087 For example, "C-u 4294967297 M-x recenter" was treated as if
15088 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15090 * xdisp.c (try_window_id): Check Emacs fixnum range before
15091 converting to 'int'.
15093 * window.c (window_scroll_line_based, Frecenter):
15094 Check that an Emacs fixnum is in range before assigning it to 'int'.
15095 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15096 values converted from Emacs fixnums.
15097 (Frecenter): Don't wrap around a line count if it is out of 'int'
15098 range; instead, treat it as an extreme value.
15099 (Fset_window_configuration, compare_window_configurations):
15100 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15102 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15103 that can exceed INT_MAX. Check that EMACS_INT value is in range
15104 before assigning it to the (possibly-narrower) index.
15105 (match_limit): Don't assume that a fixnum can fit in 'int'.
15107 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15110 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15111 (Fvertical_motion): Don't wrap around LINES values that don't fit
15112 in 'int'. Instead, treat them as extreme values. This is good
15113 enough for windows, which can't have more than INT_MAX lines anyway.
15115 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15117 * Require libxml/parser.h to avoid compilation warning.
15119 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15121 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15122 since this reportedly can destroy thread storage.
15124 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15126 * syntax.c (find_defun_start): Update all cache variables if
15127 exiting early (Bug#9401).
15129 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15131 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15133 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15134 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15135 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15137 * term.c (tty_append_glyph): New function.
15138 (produce_stretch_glyph): Static function and its prototype deleted.
15140 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15143 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15145 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15146 when checking :margin (Bug#9390).
15147 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15148 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15149 so that the name doesn't mislead. All uses changed.

15159 position beyond to_charpos, if we are scanning backwards.
15160 (move_it_vertically_backward): When DY == 0, make sure we get to
15161 the first character in the line after the newline.
15163 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15165 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15166 (ccl_driver): Do not generate an out-of-range pointer.
15167 (Fccl_execute_on_string): Remove unnecessary check for
15168 integer overflow, noted by Stefan Monnier in
15169 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15170 Remove a FIXME that didn't need fixing.
15171 Simplify the newly-introduced buffer reallocation code.
15173 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15175 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15177 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15179 Integer and memory overflow issues (Bug#9196).
15181 * doc.c (get_doc_string): Rework so that
15182 get_doc_string_buffer_size is the actual buffer size, rather than
15183 being 1 less than the actual buffer size; this makes xpalloc more
15186 * image.c (x_allocate_bitmap_record, cache_image):
15187 * xselect.c (Fx_register_dnd_atom):
15188 Simplify previous changes by using xpalloc.
15190 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15191 since either will do and ptrdiff_t is convenient with xpalloc.
15193 * charset.c (charset_table_size)
15194 (struct charset_sort_data.priority): Now ptrdiff_t.
15195 (charset_compare): Don't overflow if priorities differ greatly.
15196 (Fsort_charsets): Don't assume list length fits in int.
15197 Check for size-calculation overflow when allocating sort data.
15198 (syms_of_charset): Allocate an initial charset table that is
15199 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15201 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15203 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15204 The actual value is always <= INT_MAX, and leaving it unsigned made
15205 overflow checking harder.
15207 * dispextern.h (struct glyph_matrix.rows_allocated)
15208 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15209 with xpalloc. The values are still always <= INT_MAX.
15211 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15213 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15214 (SAFE_NALLOCA): New macro.
15216 * region-cache.c (struct boundary.pos, find_cache_boundary)
15217 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15218 (set_cache_region, invalidate_region_cache)
15219 (revalidate_region_cache, know_region_cache, region_cache_forward)
15220 (region_cache_backward, pp_cache):
15221 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15222 so that ptrdiff_t * can be passed to xpalloc.
15223 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15224 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15225 (pp_cache): Don't assume cache_len fits in int.
15226 * region-cache.h: Adjust extern decls to match.
15228 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15229 EMACS_INT, since either will do, for xpalloc.
15231 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15232 (xnmalloc, xnrealloc, xpalloc): New functions.
15234 * bidi.c (bidi_shelve_header_size): New constant.
15235 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15236 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15238 * bidi.c (bidi_cache_shrink):
15239 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15241 Don't update size of array until after memory allocation succeeds,
15242 because xmalloc/xrealloc may not return.
15243 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15244 now that we have proper integer overflow checking.
15245 (record_overlay_string, overlay_strings): Catch overflows when
15246 calculating size of overlay_str_buf.
15248 * callproc.c (Fcall_process): Check for size overflow when
15249 calculating size of args2.
15250 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15251 Normally we prefer signed values, but sticking with ptrdiff_t would
15252 require adding more-complicated checks.
15254 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15255 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15256 Redo buffer-overflow calculations to avoid integer overflow.
15257 Add a FIXME comment where memory seems to be over-allocated.
15259 * character.c (Fstring): Check for size-calculation overflow.
15261 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15262 unnecessary integer overflow. Check for size overflow.
15263 (encode_coding_object): Don't update size until xmalloc succeeds.
15265 * composite.c (get_composition_id): Check for overflow in glyph
15266 length calculations.
15268 Integer and memory overflow fixes for display code.
15269 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15270 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

15277 Don't update size until allocation succeeds.
15278 * fns.c (concat): Check for overflow in size calculations.
15279 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15280 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15283 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15284 (get_doc_string): Check for size calculation overflow.
15285 Don't update size until allocation succeeds.
15286 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15287 EMACS_INT, where ptrdiff_t will do.
15288 (Fsubstitute_command_keys): Check for string overflow.
15290 * editfns.c (set_time_zone_rule): Don't assume environment length
15292 (message_length): Now ptrdiff_t, not int.
15293 (Fmessage_box): Don't update size until allocation succeeds.
15294 Don't assume message length fits in int.
15295 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15297 * emacs.c (main): Do not reallocate argv, since there is a null at
15298 the end that can be overwritten, and this way there's no need to
15299 worry about size-calculation overflow.
15300 (sort_args): Check for size-calculation overflow.
15302 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15304 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15306 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15307 (x_set_scroll_bar_width, x_figure_window_size):
15308 Check for integer overflow.
15309 (x_set_alpha): Do not assume XINT fits in int.
15311 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15312 This is for the members text_lines, text_cols, total_lines, total_cols,
15313 where the system imposes an 'int' limit.
15315 * fringe.c (Fdefine_fringe_bitmap):
15316 Don't update size until alloc works.
15318 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15319 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15321 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15322 Check for size-calculation overflow.
15323 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15324 do, as we prefer signed integers.
15325 (id_to_widget.max_size, id_to_widget.used)
15326 (xg_store_widget_in_map, xg_remove_widget_from_map)
15327 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15328 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15329 Use and return ptrdiff_t, not int.
15330 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15331 * gtkutil.h: Change prototypes to match the above.
15333 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15334 are duplicate now that they've been promoted to lisp.h.
15335 (x_allocate_bitmap_record, x_alloc_image_color)
15336 (make_image_cache, cache_image, xpm_load):
15337 Don't update size until alloc is done.

15348 Use ptrdiff_t, not int, to count maps.
15349 (read_char_minibuf_menu_prompt): Check for overflow in size
15350 calculations. Don't update size until allocation succeeds.
15351 Redo calculations to avoid overflow.

15380 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15381 for command line length. Do not attempt to address one before the
15382 beginning of an array, as that's not portable.
15384 * term.c (max_frame_lines): Remove; unused.
15385 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15387 (encode_terminal_code, calculate_costs): Check for size
15388 calculation overflow.

15394 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15395 subtracting pointers.
15396 (gobble_line): Check for overflow more carefully. Don't update size

15410 Use ptrdiff_t, not int, for sizes.
15411 (Finternal_make_lisp_face, cache_face):
15412 Check for size calculation overflow.
15413 (cache_face): Treat size calculation overflows as if they were
15414 memory exhaustion (the usual treatment), rather than aborting.
15416 * xfns.c (x_encode_text, x_set_name_internal)
15417 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15418 sizes, since they can exceed INT_MAX in size. Check for size

15422 (xg_select): Check for size calculation overflow.
15423 Don't update size until alloc done.
15425 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15426 as sprintf is limited to int lengths.
15428 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15429 (X_LONG_MIN): New macros.
15430 Use them to make the following changes clearer.
15431 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15432 This change doesn't affect the value now, but it may help remind
15433 future maintainers not to raise the value too much later.
15434 (SELECTION_QUANTUM): Remove, replacing with ...
15435 (selection_quantum): ... new function, which avoids overflow.
15437 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15438 assumption that selection length fits in 'int'.

15451 (lisp_data_to_selection_data, x_property_data_to_lisp):

15455 Don't store size until memory allocation succeeds.
15456 (x_get_window_property): Plug memory leak on memory exhaustion.
15457 Don't double-block input; malloc is safe here. Don't assume 2**34
15458 - 4 fits in unsigned long. Add an xassert to check
15459 XGetWindowProperty overflow. Be more careful about overflow
15460 calculations, and distinguish size from memory overflow better.

15462 unsigned int is less than INT_MAX.
15463 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15464 harmful) conversions of unsigned short to int.
15465 (lisp_data_to_selection_data): Don't assume that integers
15466 in the range -65535 through -1 fit in an X unsigned short.
15467 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15468 result parameters unless successful. Rely on cons_to_unsigned
15469 to report problems with elements; the old code wasn't right anyway.
15470 (x_check_property_data): Check for int overflow; we cannot use
15471 a wider type due to X limits.
15472 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15474 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15504 * lisp.h (hash_lookup, hash_put):
15505 * minibuf.c (Ftest_completion):
15506 Use ptrdiff_t for hash table indexes, not int (which is too
15507 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15508 32-bit --with-wide-int hosts).
15510 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15511 Add a FIXME comment about memory leaks.
15512 (syms_of_charset): Don't assume xmalloc returns.

15519 with outlandish widths.
15520 * character.h (sanitize_tab_width): Rename from sanitize_width,
15521 now that we have two such functions. All uses changed.
15522 (sanitize_char_width): New inline function.
15524 Don't assume that tab-width fits in int.
15525 * character.h (sanitize_width): New inline function.

15542 exceed limits imposed by XClientMessageEvent, as well as the usual
15543 ptrdiff_t and size_t limits.
15545 * keyboard.c: Overflow, signedness and related fixes.
15546 (make_lispy_movement): Use same integer type in forward decl
15547 that is used in the definition.
15548 (read_key_sequence, keyremap_step):
15549 Change bufsize argument back to int, undoing my 2011-03-30 change.
15550 We prefer signed types, and int is wide enough here.
15551 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15552 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15553 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15554 length, not size_t. Use ptrdiff_t for index, not int.
15555 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15556 possibility of integer overflow.
15558 Overflow, signedness and related fixes for images.

15584 Prefer int to unsigned where either will do.
15585 (tiff_handler): New function, combining the cores of the
15586 old tiff_error_handler and tiff_warning_handler.
15587 This function is rewritten to use vsnprintf and thereby avoid
15588 stack buffer overflows. It uses only the features of vsnprintf
15589 that are common to both POSIX and native Microsoft.
15590 (tiff_error_handler, tiff_warning_handler): Use it.
15591 (tiff_load, gif_load, imagemagick_load_image):
15592 Don't assume :index value fits in 'int'.
15593 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15594 (imagemagick_load_image): Check that crop parameters fit into
15595 the integer types that MagickCropImage accepts. Don't assume
15596 Vimagemagick_render_type has a nonnegative value. Don't assume
15597 size_t fits in 'long'.
15598 (gs_load): Use printmax_t to print the widest integers possible.
15599 Check for integer overflow when computing image height and width.

15612 (handle_single_display_spec): If the display spec is of the form
15613 `(space ...)', and specifies display in the text area, return 2
15615 (try_cursor_movement): Check for the need to scroll more
15616 accurately, and prefer exact match for point under bidi.
15617 Don't advance `row' beyond the last row of the window.
15619 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15620 into disp_prop; all users changed.

15638 positioning on the newline at EOL of R2L text within L2R
15639 paragraph, and vice versa.
15640 (try_cursor_movement): Check continued rows, in addition to
15641 continuation rows. Fixes unwarranted scroll when point enters a
15642 continued line of R2L text within an L2R paragraph, or vice versa.
15643 (cursor_row_p): Consider the case of point being equal to
15644 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15645 from the end of a short line to the beginning of a continued line
15646 of R2L text within L2R paragraph.

15670 * xdisp.c (redisplay_window): When computing centering_position,
15671 account for the height of the header line. (Bug#8874)
15673 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15674 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15675 candidate is selected by the mouse, and that candidate has a
15676 composed character under the mouse.
15678 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15679 coordinates reported by pos-visible-in-window-p for a composed
15680 character in column zero.
15682 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15689 consider it a hit if to_charpos is anywhere in the range of the
15690 composed buffer positions.
15692 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15694 * image.c (gif_load): Don't assume that each subimage has the same
15695 dimensions as the base image. Handle disposal method that is
15696 "undefined" by the gif spec (Bug#9335).
15698 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15700 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15705 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15706 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15707 from an Org mode buffer to a Speedbar frame.
15709 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15710 a composition, take its buffer position from IT->cmp_it.charpos.
15711 Fixes cursor positioning at the beginning of a line that begins
15712 with a composed character.
15714 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15716 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15717 character bidirectional type, use STRONG_L instead. Fixes crashes
15718 in a buffer produced by `describe-categories'.
15720 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15721 members before the level stack, so they would be saved and
15722 restored when copying iterator state. Fixes incorrect reordering
15723 around TABs covered by display properties.
15725 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15727 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15811 the event loop. Get status from as_status (Bug#7276).
15813 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15814 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15815 the event loop (Bug#7276).

15841 (Fnetwork_interface_list): Allocate in increments of bytes instead
15842 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15843 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct

15855 Set IT->current to match the bidi iterator unconditionally.
15856 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15857 entry. Force push_it to save on the stack the current
15858 buffer/string position, to be restored by pop_it. Fix flags in
15859 the iterator structure wrt the object coming from a display
15860 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15861 properties. (Bug#9284)
15863 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>

15909 is non-zero, even if the data buffer is NULL. Fixes a crash in
15910 vertical-motion with longlines-mode. (Bug#9254)
15912 2011-08-05 Eli Zaretskii <eliz@gnu.org>

16052 * nsterm.h (nsfont_info): Remove voffset field.
16054 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16056 Implement strike-through and overline on NextStep (Bug#8863).
16058 * nsfont.m (nsfont_open): Use underline position provided by font,
16059 instead of hard-coded value of 2.
16060 (nsfont_draw): Call ns_draw_text_decoration instead.
16062 * nsterm.h: Add declaration for ns_draw_text_decoration.
16064 * nsterm.m (ns_draw_text_decoration): New function for drawing
16065 underline, overline, and strike-through.
16066 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16067 ns_draw_text_decoration. Change treatment of cursor drawing to
16068 accommodate underlining, etc.
16070 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16072 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16075 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16077 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16078 Without this fix, if a signal arrives just after memory fills up,
16079 'malloc' might be invoked reentrantly.
16081 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16082 In other words, assume that every image size is allowed, on non-X
16083 hosts. This assumption is probably wrong, but it lets Emacs compile.
16085 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16087 * regex.c (re_iswctype): Convert return values to boolean.
16089 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16091 * xdisp.c (compute_display_string_pos): Don't use cached display
16092 string position if the buffer had its restriction changed.
16095 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16097 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16099 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16101 Integer signedness and overflow and related fixes. (Bug#9079)
16103 * bidi.c: Integer size and overflow fixes.
16104 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16105 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16106 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16107 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16108 (bidi_find_other_level_edge):
16109 Use ptrdiff_t instead of EMACS_INT where either will do.
16110 This works better on 32-bit hosts configured --with-wide-int.
16111 (bidi_cache_ensure_space): Check for size-calculation overflow.
16112 Use % rather than repeated addition, for better worst-case speed.
16113 Don't set bidi_cache_size until after xrealloc returns, because it
16115 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16116 (bidi_cache_ensure_space): Also check that the bidi cache size
16117 does not exceed that of the largest Lisp string or buffer. See Eli
16118 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16120 * alloc.c (__malloc_size_t): Remove.
16121 All uses replaced by size_t. See Andreas Schwab's note
16122 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16124 * image.c: Improve checking for integer overflow.
16125 (check_image_size): Assume that f is nonnull, since
16126 it is always nonnull in practice. This is one less thing to
16127 worry about when checking for integer overflow later.
16128 (x_check_image_size): New function, which checks for integer
16129 overflow issues inside X.
16130 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16131 This removes the need for a memory_full check.
16132 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16133 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16134 (xbm_read_bitmap_data): Change locals back to 'int', since
16135 their values must fit in 'int'.
16136 (xpm_load_image, png_load, tiff_load):
16137 Invoke x_create_x_image_and_pixmap earlier,
16138 to avoid much needless work if the image is too large.
16139 (tiff_load): Treat overly large images as if
16140 x_create_x_image_and_pixmap failed, not as malloc failures.
16141 (gs_load): Use x_check_image_size.
16143 * gtkutil.c: Omit integer casts.
16144 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16145 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16147 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16149 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16150 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16151 would wrongly return t on a 64-bit host.
16153 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16154 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16155 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16156 and therefore cause GCC to emit a bogus diagnostic in some cases.
16158 * image.c: Integer signedness and overflow and related fixes.
16159 This is not an exhaustive set of fixes, but it's time to
16160 record what I've got.
16161 (lookup_pixel_color, check_image_size): Remove redundant decls.
16162 (check_image_size): Don't assume that arbitrary EMACS_INT values
16163 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16164 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16165 (tiff_load, imagemagick_load_image):
16166 Check for overflow in size calculations.
16167 (x_create_x_image_and_pixmap): Remove unnecessary test for
16168 xmalloc returning NULL; that can't happen.
16169 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16170 (xpm_color_bucket): Use better integer hashing function.
16171 (xpm_cache_color): Don't possibly over-allocate memory.
16172 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16173 (gif_memory_source):
16174 Use ptrdiff_t, not int or size_t, to record sizes.
16175 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16176 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16177 either works, as we prefer signed integers.
16178 (tiff_read_from_memory, tiff_write_from_memory):
16179 Return tsize_t, not size_t, since that's what the TIFF API wants.
16180 (tiff_read_from_memory): Don't fail simply because the read would
16181 go past EOF; instead, return a short read.
16182 (tiff_load): Omit no-longer-needed casts.
16183 (Fimagemagick_types): Don't assume size fits into 'int'.
16185 Improve hashing quality when configured --with-wide-int.
16186 * fns.c (hash_string): New function, taken from sxhash_string.
16187 Do not discard information about ASCII character case; this
16188 discarding is no longer needed.
16189 (sxhash-string): Use it. Change sig to match it. Caller changed.
16190 * lisp.h: Declare it.
16191 * lread.c (hash_string): Remove, since we now use fns.c's version.
16192 The fns.c version returns a wider integer if --with-wide-int is
16193 specified, so this should help the quality of the hashing a bit.
16195 * emacs.c: Integer overflow minor fix.
16196 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16197 Define only if GNU_LINUX.
16198 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16200 * dispnew.c: Integer signedness and overflow fixes.
16201 Remove unnecessary forward decls, that were a maintenance hassle.
16202 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16204 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16205 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16206 (prepare_desired_row, line_draw_cost):
16207 Use int, not unsigned, where either works.
16208 (save_current_matrix, restore_current_matrix):
16209 Use ptrdiff_t, not size_t, where either works.
16210 (init_display): Check for overflow more accurately, and without
16211 relying on undefined behavior.
16213 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16214 Remove, replacing with the new symbols in lisp.h. All uses changed.
16215 * fileio.c (make_temp_name):
16216 * filelock.c (lock_file_1, lock_file):
16217 * xdisp.c (message_dolog):
16218 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16219 Use pMd etc. instead.
16220 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16221 replacing the pWIDE etc. symbols removed from editfns.c.
16223 * keyboard.h (num_input_events): Now uintmax_t.
16224 This is (very slightly) less likely to mess up due to wraparound.
16227 * buffer.c: Integer signedness fixes.
16228 (alloc_buffer_text, enlarge_buffer_text):
16229 Use ptrdiff_t rather than size_t when either will do, as we prefer
16232 * alloc.c: Integer signedness and overflow fixes.
16233 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16234 (__malloc_size_t): Default to size_t, not to int.
16235 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16236 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16237 Prefer ptrdiff_t to size_t when either would do, as we prefer
16239 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16240 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16241 Now const. Initialize with values that are in range even if char
16243 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16244 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16245 These functions do the right thing with sizes > 2**32.
16246 (check_depth): Now ptrdiff_t, not int.
16247 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16248 Adjust to new way of storing sizes. Check for size overflow bugs
16250 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16251 slightly wrong anyway, as it missed one instance of
16252 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16253 (refill_memory_reserve): Omit needless cast to size_t.
16254 (mark_object_loop_halt): Mark as externally visible.
16256 * xselect.c: Integer signedness and overflow fixes.
16257 (Fx_register_dnd_atom, x_handle_dnd_message):
16258 Use ptrdiff_t, not size_t, since we prefer signed.
16259 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16260 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16261 x_dnd_atoms_size and x_dnd_atoms_length.
16263 * doprnt.c: Prefer signed to unsigned when either works.
16265 * doprnt.c (doprnt):
16267 * xdisp.c (vmessage):
16268 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16269 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16270 prefer signed arithmetic to avoid comparison confusion.
16271 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16272 but is a bit tricky.
16274 Assume freestanding C89 headers, string.h, stdlib.h.
16275 * data.c, doprnt.c, floatfns.c, print.c:
16276 Include float.h unconditionally.
16277 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16278 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16279 * regex.c: Likewise for stddef.h, string.h.
16280 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16281 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16282 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16283 (STDC_HEADERS): Remove obsolete defines.
16284 * sysdep.c: Include limits.h unconditionally.
16286 Assume support for memcmp, memcpy, memmove, memset.
16287 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16288 * regex.c (memcmp, memcpy):
16289 Remove; we assume C89 now.
16291 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16292 (__malloc_safe_bcopy): Remove; no longer needed.
16294 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16295 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16296 well either way, and we prefer signed to unsigned.
16298 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16300 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16301 closes the connection while we're reading (bug#9182).
16303 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16305 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16306 are specified (Bug#9168).
16308 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16310 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16311 Found by GCC static checking and --with-wide-int on a 32-bit host.
16313 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16315 * xdisp.c (compute_display_string_pos): Fix logic of caching
16316 previous display string position. Initialize cached_prev_pos to
16317 -1. Fixes slow-down at the beginning of a buffer.
16319 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16321 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16322 for attrs[LFACE_FONTSET_INDEX].
16324 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16326 * xml.c (parse_region): Remove unused local
16327 that was recently introduced.
16329 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16331 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16332 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16334 * xdisp.c (move_it_in_display_line_to): Record the best matching
16335 position for TO_CHARPOS while scanning the line, and restore it on
16336 exit if none of the characters scanned was an exact match.
16337 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16338 when exact match is impossible due to invisible text, and the
16339 lines are truncated.
16341 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16343 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16346 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16348 Fix a significant slow-down of cursor motion with C-n, C-p,
16349 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16350 auto-repeat under bidi redisplay in fontified buffers.
16351 * xdisp.c (compute_stop_pos_backwards): New function.
16352 (next_element_from_buffer): Call compute_stop_pos_backwards to
16353 find a suitable prev_stop when we find ourselves before
16355 (reseat): Don't look for prev_stop, as that could mean a very long
16357 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16358 <cached_disp_overlay_modiff>: Cache for last found display string
16360 (compute_display_string_pos): Return the cached position if asked
16361 about the same buffer in the same area of character positions, and
16362 the buffer wasn't changed since the time the display string
16363 position was cached.
16365 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16367 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16368 is an integer, which is important for empty lines. (Bug#9149)
16370 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16372 * frame.c (Fmodify_frame_parameters): In tty case, update the
16373 default face if necessary (Bug#4238).
16375 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16377 * editfns.c (Fstring_to_char): No need to explain what a character
16378 is in the docstring (Bug#6576).
16380 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16382 * xml.c (parse_region): Make sure we always return a tree.
16384 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16386 * xml.c (parse_region): If a document contains only comments,
16389 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16391 * xml.c (make_dom): Return comments, too.
16393 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16396 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16397 and the surrounding thread.
16398 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16399 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16400 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16402 * s/openbsd.h (BROKEN_SIGIO): Define.
16403 * unexelf.c (unexec) [__OpenBSD__]:
16404 Don't update the .mdebug section of the Alpha COFF symbol table.
16406 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16408 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16411 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16413 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16414 This fixes some race conditions on the permissions of any newly
16417 * alloc.c (valid_pointer_p): Use pipe, not open.
16418 This fixes some permissions issues when debugging.
16420 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16421 If fchown fails to set both uid and gid, try to set just gid,
16422 as that is sometimes allowed. Adjust the file's mode to eliminate
16423 setuid or setgid bits that are inappropriate if fchown fails.
16425 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16427 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16428 to compare Lisp_Objects.
16429 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16430 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16431 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16433 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16435 * lread.c (read_integer): Unread even EOF character.
16436 (read1): Likewise. Properly record start position of symbol.
16438 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16439 symbol character follows.
16441 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16443 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16444 This works around a problem with the previous change to Fcopy_file.
16445 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16446 and without this change, GCC might complain about discarding
16447 fchown's return value.
16449 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16451 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16453 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16455 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16457 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16459 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16460 it's used from the C level.
16462 * process.c: Use the same condition for POLL_FOR_INPUT in both
16463 keyboard.c and process.c (bug#1858).
16465 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16467 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16468 (Fgnutls_boot): Use it.
16470 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16472 * doc.c (Fsubstitute_command_keys): Revert last change.
16474 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16476 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16477 quotes the next character, and doesn't affect other longer
16478 sequences (bug#8935).
16480 * lread.c (syms_of_lread): Clarify that is isn't only
16481 `eval-buffer' and `eval-defun' that's affected by
16482 `lexical-binding' (bug#8460).
16484 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16486 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16487 bidi redisplay when a line includes both an image and is truncated.
16489 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16491 Fix minor problems found by static checking.
16492 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16493 (elsz): Now a signed constant, not a size_t var. We prefer signed
16494 types to unsigned, to avoid integer comparison confusion. Without

16545 the iterator is before prev_stop.

17027 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17064 Random fixes. E.g., (random) never returned negative values.
17065 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17066 subseconds part to the entropy, as that's a bit more random.
17067 Prefer signed to unsigned, since the signedness doesn't matter and
17068 in general we prefer signed. When given a limit, use a
17069 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17070 latter isn't right if USE_2_TAGS_FOR_INTS.
17071 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17072 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17085 This is more efficient than Ffile_directory_p and avoids a minor race.

17089 * buffer.c (Foverlay_put): Say what the return value is
17092 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17096 error be more correct.
17098 * fns.c (Frequire): Remove the mention of the .gz files, since

17112 Qgnutls_bootprop_verify_error (which is no longer used).
17114 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17115 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17116 Also (re)move comments that are misplaced or no longer relevant.

17217 * eval.c (struct backtrace): Simplify and port the data structure.
17218 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17219 signed bit field, as this assumption is not portable and it makes
17220 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17221 "char debug_on_exit : 1" as this is not portable either; instead,
17222 use the portable "unsigned int debug_on_exit : 1". Remove unused
17223 member evalargs. Remove obsolete comments about cc bombing out.
17225 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17371 * terminal.c (syms_of_terminal):
17372 * textprop.c (syms_of_textprop):

17379 * xmenu.c (syms_of_xmenu):
17380 * xsettings.c (syms_of_xsettings):
17381 * xterm.c (syms_of_xterm): Use DEFSYM.
17383 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
17385 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
17387 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17389 Integer and buffer overflow fixes (Bug#8873).
17391 * print.c (printchar, strout): Check for string overflow.
17392 (PRINTPREPARE, printchar, strout):
17393 Don't set size unless allocation succeeds.
17395 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17396 for sizes. Check for string overflow more accurately.
17397 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17399 * macros.c: Integer and buffer overflow fixes.
17400 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17401 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17402 Use ptrdiff_t, not int, for sizes.
17403 Don't increment bufsize until after realloc succeeds.
17404 Check for size-calculation overflow.
17405 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17407 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17409 * lread.c: Integer overflow fixes.
17410 (read_integer): Radix is now EMACS_INT, not int,
17411 to improve quality of diagnostics for out-of-range radices.
17412 Calculate buffer size correctly for out-of-range radices.
17413 (read1): Check for integer overflow in radices, and in
17414 read-circle numbers.
17415 (read_escape): Avoid int overflow.
17416 (Fload, openp, read_buffer_size, read1)
17417 (substitute_object_recurse, read_vector, read_list, map_obarray):
17418 Use ptrdiff_t, not int, for sizes.
17419 (read1): Use EMACS_INT, not int, for sizes.
17420 Check for size overflow.
17422 * image.c (cache_image): Check for size arithmetic overflow.
17424 * lread.c: Integer overflow issues.
17425 (saved_doc_string_size, saved_doc_string_length)
17426 (prev_saved_doc_string_size, prev_saved_doc_string_length):
17427 Now ptrdiff_t, not int.
17428 (read1): Don't assume doc string length fits in int. Check for
17429 out-of-range doc string lengths.
17430 (read_list): Don't assume file position fits in int.
17431 (read_escape): Check for hex character overflow.
17433 2011-06-22 Leo Liu <sdl.web@gmail.com>
17435 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17436 Move to minibuffer.el.
17438 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17440 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17441 The following patches are for when GLYPH_DEBUG && !XASSERT.
17442 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17443 * dispnew.c (flush_stdout):
17444 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17445 Mark as externally visible.
17446 * dispnew.c (check_window_matrix_pointers): Now static.
17447 * dispnew.c (window_to_frame_vpos):
17448 * xfns.c (unwind_create_frame):
17449 * xterm.c (x_check_font): Remove unused local.
17450 * scroll.c (CHECK_BOUNDS):
17451 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17452 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17453 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17454 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17455 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17457 (debug_method_add): Use va_list and vsprintf rather than relying
17458 on undefined behavior with wrong number of arguments.
17459 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17460 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17461 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17462 since we're not interested in debugging glyphs with old libraries.
17463 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17464 GCC 4.6.0's static checking.
17466 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17468 Integer overflow and signedness fixes (Bug#8873).
17469 A few related buffer overrun fixes, too.

17477 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17478 (x_create_bitmap_from_xpm_data):
17479 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17480 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17482 * xfaces.c (load_pixmap):
17483 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17484 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17485 (.bitmaps_last, struct x_output.icon_bitmap):
17486 Use ptrdiff_t, not int, for bitmap indexes.
17487 (x_allocate_bitmap_record): Check for size overflow.
17488 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17490 Use ptrdiff_t, not int, for overlay counts.
17491 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17492 * editfns.c (overlays_around, get_pos_property):
17493 * textprop.c (get_char_property_and_overlay):
17494 * xdisp.c (next_overlay_change, note_mouse_highlight):
17495 * xfaces.c (face_at_buffer_position):
17496 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17497 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17498 (Fnext_overlay_change, Fprevious_overlay_change)
17499 (mouse_face_overlay_overlaps, Foverlays_in):
17500 Use ptrdiff_t, not int, for sizes.
17501 (overlays_at, overlays_in): Check for size-calculation overflow.
17503 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17505 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17506 (x_session_initialize): Do not assume string length fits in int.
17508 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17509 This is unlikely, but can occur if DPI is outlandish.
17511 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17512 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17514 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17515 * xrdb.c (magic_file_p, search_magic_path):
17516 Omit last arg SUFFIX; it was always 0. All callers changed.
17517 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17519 * xfont.c (xfont_match): Avoid need for strlen.
17521 * xfns.c: Don't assume strlen fits in int.
17522 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17524 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17525 not unsigned long, as we prefer signed integers. All callers changed.
17526 Detect integer overflow in repeat count.
17527 (message_dolog): Don't assume print length fits in 39 bytes.
17528 (display_mode_element): Don't assume strlen fits in int.
17530 * termcap.c: Don't assume sizes fit in int and never overflow.
17531 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17532 (gobble_line): Check for size-calculation overflow.
17534 * minibuf.c (Fread_buffer):
17535 * lread.c (intern, intern_c_string):
17536 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17537 Don't assume string length fits in int.
17539 * keyboard.c (parse_tool_bar_item):
17540 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17542 * font.c: Don't assume string length fits in int.
17543 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17544 Use ptrdiff_t, not int.
17545 (font_intern_prop): Don't assume string length fits in int.
17546 Don't assume integer property fits in fixnum.
17547 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17549 * filelock.c: Fix some buffer overrun and integer overflow issues.
17550 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17551 Reformulate so as not to need the command string.
17552 Invoke gzip -cd rather than gunzip, as it's more portable.
17553 (lock_info_type, lock_file_1, lock_file):
17554 Don't assume pid_t and time_t fit in unsigned long.
17555 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17556 (current_lock_owner): Prefer signed type for sizes.
17557 Use memcpy, not strncpy, where memcpy is what is really wanted.
17558 Don't assume (via atoi) that time_t and pid_t fit in int.
17559 Check for time_t and/or pid_t out of range, e.g., via a network share.
17560 Don't alloca where an auto var works fine.
17562 * fileio.c: Fix some integer overflow issues.
17563 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17564 Don't assume string length fits in int.
17565 (directory_file_name): Don't assume string length fits in long.
17566 (make_temp_name): Don't assume pid fits in int, or that its print
17567 length is less than 20.
17569 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17571 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17573 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17575 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17576 We prefer signed integers, even for size calculations.
17578 * emacs.c: Don't assume string length fits in 'int'.
17579 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17580 (main): Don't invoke strlen when not needed.
17582 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17583 (XD_DEBUG_MESSAGE): Don't waste a byte.
17585 * callproc.c (getenv_internal_1, getenv_internal)
17586 (Fgetenv_internal):
17587 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17589 * lread.c (invalid_syntax): Omit length argument.
17590 All uses changed. This doesn't fix a bug, but it simplifies the
17591 code away from its former Hollerith-constant appearance, and it's
17592 one less 'int' to worry about when looking at integer-overflow issues.
17593 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17595 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17596 This didn't break anything, but it didn't help either.
17597 It's confusing to put a bogus integer in a place where the actual
17598 value does not matter.
17599 (LIST_END_P): Remove unused macro and its bogus comment.
17600 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17602 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17603 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17605 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17606 We prefer signed types, and the value cannot exceed the EMACS_INT
17607 range anyway (because otherwise the length would not be representable).
17608 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17609 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17610 This avoids a GCC warning when WIDE_EMACS_INT.
17612 * indent.c (sane_tab_width): New function.
17613 (current_column, scan_for_column, Findent_to, position_indentation)
17614 (compute_motion): Use it. This is just for clarity.
17615 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17617 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17619 * lisp.h (lint_assume): New macro.
17620 * composite.c (composition_gstring_put_cache):
17621 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17623 * editfns.c, insdel.c:
17624 Omit unnecessary forward decls, to simplify future changes.
17626 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17628 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17630 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17631 Use much-faster test for byte-length change.
17632 Don't assume string byte-length fits in 'int'.
17633 Check that character arg fits in 'int'.
17634 (mapcar1): Declare byte as byte, for clarity.
17636 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17638 * fns.c (concat): Catch string overflow earlier.
17639 Do not rely on integer wraparound.
17641 * dispextern.h (struct it.overlay_strings_charpos)
17642 (struct it.selective): Now EMACS_INT, not int.
17643 * xdisp.c (forward_to_next_line_start)
17644 (back_to_previous_visible_line_start)
17645 (reseat_at_next_visible_line_start, next_element_from_buffer):
17646 Don't arbitrarily truncate the value of 'selective' to int.
17648 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17650 * composite.c: Don't truncate sizes to 'int'.
17651 (composition_gstring_p, composition_reseat_it)
17652 (composition_adjust_point): Use EMACS_INT, not int.
17653 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17654 not EMACS_UINT, for indexes.
17656 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17658 * buffer.c: Include <verify.h>.
17659 (struct sortvec.priority, struct sortstr.priority):
17660 Now EMACS_INT, not int.
17661 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17662 (struct sortstr.size, record_overlay_string)
17663 (struct sortstrlist.size, struct sortlist.used):
17664 Don't truncate size to int.
17665 (record_overlay_string): Check for size-calculation overflow.
17666 (init_buffer_once): Check at compile-time, not run-time.
17668 2011-06-22 Jim Meyering <meyering@redhat.com>
17670 Don't leak an XBM-image-sized buffer
17671 * image.c (xbm_load): Free the image buffer after using it.
17673 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17676 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17677 that Sun C diagnosed.
17678 * fns.c (secure_hash): Fix pointer signedness issue.
17679 * intervals.c (static_offset_intervals): New function.
17680 (offset_intervals): Use it.
17682 2011-06-21 Leo Liu <sdl.web@gmail.com>
17685 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17688 * fns.c (secure_hash): Rename from crypto_hash_function and change
17689 the first arg to accept symbols.
17690 (Fsecure_hash): New primitive.
17691 (syms_of_fns): New symbols.
17693 2011-06-20 Deniz Dogan <deniz@dogan.se>
17695 * process.c (Fset_process_buffer): Clarify return value in
17698 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17700 * dispnew.c (add_window_display_history): Use BVAR.
17702 * xdisp.c (debug_method_add): Use BVAR.
17703 (check_window_end, dump_glyph_matrix, dump_glyph)
17704 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17706 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17709 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17710 check till after the cache is created in init_frame_faces.
17712 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17714 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17716 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17718 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17719 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17720 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17722 Improve buffer-overflow checking (Bug#8873).
17723 * fileio.c (Finsert_file_contents):
17724 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17725 Remove the old (too-loose) buffer overflow checks.
17726 They weren't needed, since make_gap checks for buffer overflow.
17727 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17728 The old code merely checked for Emacs fixnum overflow, and relied
17729 on undefined (wraparound) behavior. The new code avoids undefined
17730 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17732 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17733 Tune. Don't use wider integers than needed. Don't use alloca.
17734 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17736 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17738 * insdel.c, lisp.h (buffer_overflow): New function.
17739 (insert_from_buffer_1, replace_range, replace_range_2):
17740 * insdel.c (make_gap_larger):
17741 * editfns.c (Finsert_char):
17742 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17744 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17746 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17748 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17750 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17751 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17753 * fileio.c: Don't assume EMACS_INT fits in off_t.
17754 (emacs_lseek): New static function.
17755 (Finsert_file_contents, Fwrite_region): Use it.
17756 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17758 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17760 * fns.c: Don't overflow int when computing a list length.
17761 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17762 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17763 truncation on 64-bit hosts. Check for QUIT every
17764 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17765 faster and is responsive enough.
17766 (Flength): Report an error instead of overflowing an integer.
17767 (Fsafe_length): Return a float if the value is not representable
17768 as a fixnum. This shouldn't happen except in contrived situations.
17769 (Fnthcdr, Fsort): Don't assume list length fits in int.
17770 (Fcopy_sequence): Don't assume vector length fits in int.
17772 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17773 (header_size, word_size): New constants.
17774 (allocate_vectorlike): Don't check size overflow here.
17775 (allocate_vector): Check it here instead, since this is the only
17776 caller of allocate_vectorlike that could cause overflow.
17777 Check that the new vector's length is representable as a fixnum.
17779 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17780 The previous code was bogus. For example, next_almost_prime (32)
17781 returned 39, which is undesirable as it is a multiple of 3; and
17782 next_almost_prime (24) returned 25, which is a multiple of 5 so
17783 why was the code bothering to check for multiples of 7?
17785 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17787 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17789 Variadic C functions now count arguments with ptrdiff_t.
17790 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17791 Back then I didn't know that the Emacs coding style prefers signed int.
17792 Also, in the meantime I found a few more instances where arguments
17793 were being counted with int, which may truncate counts on 64-bit
17794 machines, or EMACS_INT, which may be unnecessarily wide.
17795 * lisp.h (struct Lisp_Subr.function.aMANY)
17796 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17797 Arg counts are now ptrdiff_t, not size_t.
17798 All variadic functions and their callers changed accordingly.
17799 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17800 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17801 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17802 * callint.c (Fcall_interactively): Check arg count for overflow,
17803 to avoid potential buffer overrun. Use signed char, not 'int',
17804 for 'varies' array, so that we needn't bother to check its size
17805 calculation for overflow.
17806 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17807 * eval.c (apply_lambda):
17808 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17809 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17810 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17812 * callint.c (Fcall_interactively): Don't use index var as event count.
17814 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17815 * mem-limits.h (SIZE): Remove; no longer used.
17817 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17819 Remove unnecessary casts.
17820 * xterm.c (x_term_init):
17821 * xfns.c (x_set_border_pixel):
17822 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17823 These aren't needed now that we assume ANSI C.
17825 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17826 It's more likely to cause problems (due to unsigned overflow)
17829 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17831 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17833 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17835 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17837 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17839 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17841 GLYPH_CODE_FACE returns EMACS_INT, not int.
17842 * dispextern.h (merge_faces):
17843 * xfaces.c (merge_faces):
17844 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17845 Don't assume EMACS_INT fits in int.
17847 * character.h (CHAR_VALID_P): Remove unused parameter.
17848 * fontset.c, lisp.h, xdisp.c: All uses changed.
17850 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17852 * fns.c (concat): Minor tuning based on overflow analysis.
17853 This doesn't fix any bugs. Use int to hold character, instead
17854 of constantly refetching from Emacs object. Use XFASTINT, not
17855 XINT, for value known to be a character. Don't bother comparing
17856 a single byte to 0400, as it's always less.
17858 * floatfns.c (Fexpt):
17859 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17861 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17864 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17866 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17867 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17868 incorrectly succeed when S was a string, because 4294967386 was
17869 truncated before it was used.
17871 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17872 Otherwise, an out-of-range integer could cause undefined behavior
17875 * composite.c: Use int, not EMACS_INT, for characters.
17876 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17877 EMACS_INT, for values that are known to be in character range.
17878 This doesn't fix any bugs but is the usual style inside Emacs and
17879 may generate better code on 32-bit machines.
17881 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17882 This is for reasons similar to the recent CHAR_STRING fix.
17883 * charset.c (Fencode_char): Check that character arg is actually
17884 a character. Pass an int to ENCODE_CHAR.
17885 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17886 wider than 'int', as a compile-time check to prevent future regressions
17889 * character.c (char_string): Remove unnecessary casts.
17891 Make sure a 64-bit char is never passed to CHAR_STRING.
17892 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17893 by silently ignoring the top 32 bits, allowing some values
17894 that were far too large to be valid characters.
17895 * character.h: Include <verify.h>.
17896 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17897 arguments are no wider than unsigned, as a compile-time check
17898 to prevent future regressions in this area.
17900 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17901 (Fsubst_char_in_region):
17903 * xdisp.c (decode_mode_spec_coding):
17904 Adjust to CHAR_STRING's new requirement.
17905 * editfns.c (Finsert_char, Fsubst_char_in_region):
17906 * fns.c (concat): Check that character args are actually
17907 characters. Without this test, these functions did the wrong
17908 thing with wildly out-of-range values on 64-bit hosts.
17910 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17911 These casts should not be needed on 32-bit hosts, either.
17912 * keyboard.c (read_char):
17913 * lread.c (Fload): Remove casts to unsigned.
17915 * lisp.h (UNSIGNED_CMP): New macro.
17916 This fixes comparison bugs on 64-bit hosts.
17917 (ASCII_CHAR_P): Use it.
17918 * casefiddle.c (casify_object):
17919 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17920 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17921 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17922 * dispextern.h (FACE_FROM_ID):
17923 * keyboard.c (read_char): Use UNSIGNED_CMP.
17925 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17926 not to EMACS_INT, to avoid GCC warning.
17928 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17930 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17931 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17932 isn't needed on 32-bit machines.
17934 * buffer.c (Fgenerate_new_buffer_name):
17935 Use EMACS_INT for count, not int.
17936 (advance_to_char_boundary): Return EMACS_INT, not int.
17938 * data.c (Qcompiled_function): Now static.
17940 * window.c (window_body_lines): Now static.
17942 * image.c (gif_load): Rename local to avoid shadowing.
17944 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17945 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17946 * alloc.c (make_save_value): Integer argument is now of type
17947 ptrdiff_t, not int.
17948 (mark_object): Use ptrdiff_t, not int.
17949 * lisp.h (pD): New macro.
17950 * print.c (print_object): Use it.
17952 * alloc.c: Use EMACS_INT, not int, to count objects.
17953 (total_conses, total_markers, total_symbols, total_vector_size)
17954 (total_free_conses, total_free_markers, total_free_symbols)
17955 (total_free_floats, total_floats, total_free_intervals)
17956 (total_intervals, total_strings, total_free_strings):
17957 Now EMACS_INT, not int. All uses changed.
17958 (Fgarbage_collect): Compute overall total using a double, so that
17959 integer overflow is less likely to be a problem. Check for overflow
17960 when converting back to an integer.
17961 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17962 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17963 These were 'int' variables that could overflow on 64-bit hosts;
17964 they were never used, so remove them instead of repairing them.
17965 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17966 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17967 Previously, this ceilinged at INT_MAX, but that doesn't work on
17969 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17971 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17972 (allocate_vectorlike): Check for ptrdiff_t overflow.
17973 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17974 when a (possibly-narrower) signed value would do just as well.
17975 We prefer using signed arithmetic, to avoid comparison confusion.
17977 * alloc.c: Catch some string size overflows that we were missing.
17978 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17979 for convenience in STRING_BYTES_MAX.
17980 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17981 The definition here is exact; the one in lisp.h was approximate.
17982 (allocate_string_data): Check for string overflow. This catches
17983 some instances we weren't catching before. Also, it catches
17984 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17985 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17986 and ptrdiff_t and EMACS_INT are both 64 bits.
17988 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17989 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17990 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17992 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17994 * alloc.c (Fmake_string): Check for out-of-range init.
17996 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17998 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18000 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18002 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

18013 and height if HAVE_GTK3 (Bug#8505).
18014 (scroll_bar_width_for_theme): New variable.
18015 (update_theme_scrollbar_width): New function.
18016 (xg_get_default_scrollbar_width): Move code to
18017 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18018 (xg_initialize): Call update_theme_scrollbar_width.
18020 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18022 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18024 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18026 * frame.c (make_frame): Call other_buffer_safely instead of
18029 * window.c (temp_output_buffer_show): Call display_buffer with
18030 second argument Vtemp_buffer_show_specifiers and reset latter
18031 immediately after the call.
18032 (Vtemp_buffer_show_specifiers): New variable.
18033 (auto_window_vscroll_p, next_screen_context_lines)
18034 (Vscroll_preserve_screen_position): Remove leading asterisks from

18041 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18042 (record_buffer): Remove unused local.
18043 * frame.c (other_visible_frames, frame_buffer_list): Now static.

18057 wasn't returning anything.
18058 (compare_window_configurations): Remove unused locals.
18059 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

18079 * window.c (delete_deletable_window): Re-add.
18080 (Fset_window_configuration): Rewrite to handle dead buffers and
18081 consequently deletable windows.
18082 (window_tree, Fwindow_tree): Remove. Supply functionality in
18084 (compare_window_configurations): Simplify code.

18217 Remove static from declaration of Qdelete_window, it's
18218 temporarily needed by Fbury_buffer.
18219 (replace_window): Don't assign orig_top_line and
18221 (Fdelete_window, delete_window): Remove. Window deletion is

18223 (window_loop): Remove DELETE_OTHER_WINDOWS case.
18224 Replace Fdelete_window calls with calls to Qdelete_window.
18225 (Fdelete_other_windows): Remove. Deleting other windows is

18630 * gnutls.c: Use Emacs's memory allocators.
18631 Without this change, the gnutls library would invoke malloc etc.
18632 directly, which causes problems on non-SYNC_INPUT hosts, and which
18633 runs afoul of improving memory_full behavior. (Bug#8761)
18634 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18635 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18636 xfree instead of the default malloc, realloc, free.
18637 (Fgnutls_boot): No need to check for memory allocation failure,
18638 since xmalloc does that for us.

18669 Check for integer overflow with large hash tables.
18670 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18671 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18672 (SXHASH_REDUCE): New macro.
18673 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18674 Use it instead of discarding useful hash info with large hash values.
18675 (sxhash_float): New function.
18676 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18677 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18678 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18679 Rewrite to use FIXNUM_BITS, as this simplifies things.
18680 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18681 Adjust signatures to match updated version of code.
18682 (consing_since_gc): Now EMACS_INT, since a single hash table can
18683 use more than INT_MAX bytes.
18685 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18687 Make it possible to build with GCC-4.6+ -O2 -flto.
18689 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18691 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18693 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18694 Call minibuffer-inactive-mode.
18696 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18698 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18699 Update dependencies.
18701 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18703 * data.c (init_data): Remove code for UTS, this system is not
18706 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18708 Don't force ./temacs to start in terminal mode.
18710 * frame.c (make_initial_frame): Initialize faces in all cases, not
18711 only when CANNOT_DUMP is defined.
18712 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18714 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18716 * dispnew.c (add_window_display_history): Use const for the string
18717 pointer. Remove declaration, not needed.
18719 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18721 Use 'inline', not 'INLINE'.
18722 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18723 * alloc.c, fontset.c (INLINE): Remove.
18724 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18725 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18726 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18727 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18728 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18730 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18732 Make it possible to run ./temacs.
18734 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18735 syms_of_callproc does the same thing. Remove test for
18736 "initialized", do it in the caller.
18737 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18739 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18741 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18742 (read_minibuf): Use get_minibuffer.
18743 (syms_of_minibuf): Use DEFSYM.
18744 (Qmetadata): New var.
18745 * data.c (Qbuffer): Don't make it static.
18746 (syms_of_data): Use DEFSYM.
18748 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18750 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18751 (CCL_CODE_MIN): New macro.
18753 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18755 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18757 * eval.c (Qdebug): Now static.
18758 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18759 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18760 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18762 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18764 * image.c: Various fixes to ImageMagick code comments.
18765 (Fimagemagick_types): Doc fix.
18767 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18769 Minor fixes prompted by GCC 4.6.0 warnings.
18771 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18773 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18774 (x_clipboard_manager_save_all): Move extern decl to ...
18775 * xterm.h: ... here, so that it can be checked for consistency.
18777 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18779 * xselect.c (x_clipboard_manager_save_frame)
18780 (x_clipboard_manager_save_all): New functions.
18781 (Fx_clipboard_manager_save): Lisp function deleted.
18783 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18784 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18786 * xterm.h: Update prototype.
18788 2011-05-28 William Xu <william.xwl@gmail.com>
18790 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18791 exiting (Bug#8239).
18793 2011-05-28 Jim Meyering <meyering@redhat.com>
18795 Avoid a sign-extension bug in crypto_hash_function.
18796 * fns.c (to_uchar): Define.
18797 (crypto_hash_function): Use it to convert some newly-signed
18798 variables to unsigned, to avoid sign-extension bugs. For example,
18799 without this change, (md5 "truc") would evaluate to
18800 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18801 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18802 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18804 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18806 Integer overflow fixes.
18808 * dbusbind.c: Serial number integer overflow fixes.
18809 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18810 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18811 to hold a serial number that is too large for a fixnum.
18812 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18813 Check for serial numbers out of range. Decode any serial number
18814 that was so large that it became a float. (Bug#8722)
18816 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18817 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18818 Use XFASTINT rather than XUINT when numbers are nonnegative.
18819 (xd_append_arg, Fdbus_method_return_internal):
18820 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18821 arguments, check that Lisp number is nonnegative, rather than
18822 silently wrapping negative numbers around. (Bug#8722)
18823 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18826 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18828 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18830 ccl: Add integer overflow checks.
18831 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18832 (IN_INT_RANGE): New macros.
18833 (ccl_driver): Use them to check for integer overflow when
18834 decoding a CCL program. Many of the new checks are whether XINT (x)
18835 fits in int; it doesn't always, on 64-bit hosts. The new version
18836 doesn't catch all possible integer overflows, but it's an
18837 improvement. (Bug#8719)
18839 * alloc.c (make_event_array): Use XINT, not XUINT.
18840 There's no need for unsigned here.
18842 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18843 This follows up to the 2011-05-06 change that substituted uintptr_t
18844 for EMACS_INT. This case wasn't caught back then.
18846 Rework Fformat to avoid integer overflow issues.
18847 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18848 now (part of C89). Include <verify.h>.
18849 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18850 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18851 (Fformat): Avoid the prepass trying to compute sizes; it was only
18852 approximate and thus did not catch overflow reliably. Instead, walk
18853 through the format just once, formatting and computing sizes as we go,
18854 checking for integer overflow at every step, and allocating a larger
18855 buffer as needed. Keep track separately whether the format is
18856 multibyte. Keep only the most-recently calculated precision, rather
18857 than them all. Record whether each argument has been converted to
18858 string. Use EMACS_INT, not int, for byte and char and arg counts.
18859 Support field widths and precisions larger than INT_MAX. Avoid
18860 sprintf's undefined behavior with conversion specifications such as %#d
18861 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18862 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18863 formatting out-of-range floating point numbers with int
18864 formats. (Bug#8668)
18866 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18868 * data.c: Avoid integer truncation in expressions involving floats.
18869 * data.c: Include <intprops.h>.
18870 (arith_driver): When there's an integer overflow in an expression
18871 involving floating point, convert the integers to floating point
18872 so that the resulting value does not suffer from catastrophic
18873 integer truncation. For example, on a 64-bit host (* 4
18874 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18875 Do not rely on undefined behavior after integer overflow.
18877 merge count_size_as_multibyte, parse_str_to_multibyte
18878 * character.c, character.h (count_size_as_multibyte):
18879 Rename from parse_str_to_multibyte; all uses changed.
18880 Check for integer overflow.
18881 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18882 since it's now a duplicate of the other. This is more of
18883 a character than a buffer op, so better that it's in character.c.
18884 * fns.c, print.c: Adjust to above changes.
18886 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18888 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18890 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18892 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18893 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18894 (x_clipboard_manager_save): Now static.
18895 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18897 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18898 (crypto_hash_function): Now static.
18899 Fix pointer signedness problems. Avoid unnecessary initializations.
18901 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18903 * termhooks.h (Vselection_alist): Make it terminal-local.
18905 * terminal.c (create_terminal): Initialize it.
18907 * xselect.c: Support for clipboard managers.
18908 (Vselection_alist): Move to termhooks.h as terminal-local var.
18909 (LOCAL_SELECTION): New macro.
18910 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18911 (symbol_to_x_atom): Remove gratuitous arg.
18912 (x_handle_selection_request, lisp_data_to_selection_data)
18913 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18914 (x_own_selection, x_get_local_selection, x_convert_selection):
18915 New arg, specifying work frame. Use terminal-local Vselection_alist.
18916 (some_frame_on_display): Delete unused function.
18917 (Fx_own_selection_internal, Fx_get_selection_internal)
18918 (Fx_disown_selection_internal, Fx_selection_owner_p)
18919 (Fx_selection_exists_p): New optional frame arg.
18920 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18921 (x_handle_selection_clear): Don't treat other terminals with the
18922 same keyboard specially. Use the terminal-local Vselection_alist.
18923 (x_clear_frame_selections): Use Frun_hook_with_args.
18925 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18927 * xterm.h: Add support for those atoms.
18929 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18931 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18932 (converted_selections, conversion_fail_tag): New global variables.
18933 (x_selection_request_lisp_error): Free the above.
18934 (x_get_local_selection): Remove unnecessary code.
18935 (x_reply_selection_request): Args changed; handle arbitrary array
18936 of converted selections stored in converted_selections.
18937 Separate the XChangeProperty and SelectionNotify steps.
18938 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18939 (x_convert_selection): New function.
18940 (x_handle_selection_event): Simplify.
18941 (x_get_foreign_selection): Don't ignore incoming requests while
18942 waiting for an answer; this will fail when we implement
18943 SAVE_TARGETS, and seems unnecessary anyway.
18944 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18945 (Vx_sent_selection_functions): Doc fix.
18947 2011-05-26 Leo Liu <sdl.web@gmail.com>
18949 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18951 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18953 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18955 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18956 for fringe update if it has periodic bitmap.
18957 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18958 and fringe_bitmap_periodic_p.
18960 * fringe.c (get_fringe_bitmap_data): New function.
18961 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18962 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18963 row. Mark glyph row for fringe update if periodicity changed.
18965 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18966 for fringe update unless it has periodic bitmap.
18968 2011-05-25 Kenichi Handa <handa@m17n.org>
18970 * xdisp.c (get_next_display_element): Set correct it->face_id for
18971 a static composition.
18973 2011-05-24 Leo Liu <sdl.web@gmail.com>
18976 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18978 * fns.c (crypto_hash_function, Fsha1): New function.
18979 (Fmd5): Use crypto_hash_function.
18980 (syms_of_fns): Add Ssha1.
18982 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18984 * gnutls.c: Remove unused macros.
18985 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18986 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18987 Remove macros that are defined and never used.
18988 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18990 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18992 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18993 (Fx_get_selection_internal): Minor cleanup.
18994 (Fx_own_selection_internal): Rename arguments for consistency with
18997 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18999 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19001 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19003 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19005 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19007 * dispnew.c (scrolling_window): Don't exclude the case that the
19008 last enabled row in the desired matrix touches the bottom boundary.
19010 2011-05-21 Glenn Morris <rgm@gnu.org>
19012 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19013 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19014 and add some more files.
19016 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19018 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19019 report_file_error introduced by the change from 2011-05-07.
19021 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19023 * systime.h (Time): Define only if emacs is defined.
19024 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19025 where the include path doesn't have X11/X.h by default. See
19026 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19028 2011-05-20 Kenichi Handa <handa@m17n.org>
19030 * composite.c (find_automatic_composition): Fix previous change.
19032 2011-05-20 Glenn Morris <rgm@gnu.org>
19034 * lisp.mk: New file, split from Makefile.in.
19035 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19036 (shortlisp): Remove.
19037 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19039 2011-05-19 Glenn Morris <rgm@gnu.org>
19041 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19042 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19043 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19044 (lisp): Set the order to that of loadup.el.
19045 (shortlisp): Make it a copy of $lisp.
19046 (SOME_MACHINE_LISP): Remove.
19047 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19048 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19050 2011-05-18 Kenichi Handa <handa@m17n.org>
19052 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19053 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19054 (find_automatic_composition): Mostly rewrite for efficiency.
19056 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19058 * makefile.w32-in: Update dependencies.
19060 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19062 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19063 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19065 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19067 Fix some integer overflow issues, such as string length overflow.
19069 * insdel.c (count_size_as_multibyte): Check for string overflow.
19071 * character.c (lisp_string_width): Check for string overflow.
19072 Use EMACS_INT, not int, for string indexes and lengths; in
19073 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19074 the resulting string length overflows an EMACS_INT; instead,
19075 report a string overflow if no precision given. When checking for
19076 precision exhaustion, use a check that cannot possibly have
19077 integer overflow. (Bug#8675)
19078 * character.h (lisp_string_width): Adjust to new signature.
19080 * alloc.c (string_overflow): New function.
19081 (Fmake_string): Use it. This doesn't change behavior, but saves
19082 a few bytes and will simplify future changes.
19083 * character.c (string_escape_byte8): Likewise.
19084 * lisp.h (string_overflow): New decl.
19086 Fixups, following up to the user-interface timestamp change.
19087 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19088 for UI timestamps, instead of unsigned long.
19089 * msdos.c (mouse_get_pos): Likewise.
19090 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19091 * w32gui.h (Time): Define by including "systime.h" rather than by
19092 declaring it ourselves. (Bug#8664)
19094 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19095 * image.c (clear_image_cache): Likewise.
19097 * term.c (term_mouse_position): Don't assume time_t wraparound.
19099 Be more systematic about user-interface timestamps.
19100 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19101 and sometimes 'EMACS_UINT', to represent these timestamps.
19102 This change causes it to use 'Time' uniformly, as that's what X uses.
19103 This makes the code easier to follow, and makes it easier to catch
19104 integer overflow bugs such as Bug#8664.
19105 * frame.c (Fmouse_position, Fmouse_pixel_position):
19106 Use Time, not unsigned long, for user-interface timestamps.
19107 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19108 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19109 * keyboard.h (last_event_timestamp): Likewise.
19110 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19111 * menu.h (xmenu_show): Likewise.
19112 * term.c (term_mouse_position): Likewise.
19113 * termhooks.h (struct input_event.timestamp): Likewise.
19114 (struct terminal.mouse_position_hook): Likewise.
19115 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19116 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19117 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19118 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19119 what it was before.
19120 * menu.h, termhooks.h: Include "systime.h", for Time.
19122 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19123 Don't assume that the difference between two unsigned long values
19124 can fit into an integer. At this point, we know button_down_time
19125 <= event->timestamp, so the difference must be nonnegative, so
19126 there's no need to cast the result if double-click-time is
19127 nonnegative, as it should be; check that it's nonnegative, just in
19128 case. This bug is triggered when events are more than 2**31 ms
19129 apart (about 25 days). (Bug#8664)
19131 * xselect.c (last_event_timestamp): Remove duplicate decl.
19132 (x_own_selection): Remove needless cast to unsigned long.
19134 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19135 that always fit in int. Use a sentinel instead of a counter, to
19136 avoid a temp and to allay GCC's concerns about possible int overflow.
19137 * frame.h (struct frame): Use int for menu_bar_items_used
19138 instead of EMACS_INT, since it always fits in int.
19140 * menu.c (grow_menu_items): Check for int overflow.
19142 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19144 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19145 Before, the code was not consistent. These values cannot exceed
19146 2**31 - 1 so there's no need to make them unsigned.
19147 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19148 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19149 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19151 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19153 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19154 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19155 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19156 presumably because the widths might not match.
19158 * window.c (size_window): Avoid needless test at loop start.
19160 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19162 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19164 2011-05-12 Drew Adams <drew.adams@oracle.com>
19166 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19168 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19170 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19171 `width' to `bar_area_x' and `bar_area_width', respectively.
19172 (x_scroll_run): Take account of fringe background extension.
19174 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19175 Rename local vars `left' and `width' to `bar_area_x' and
19176 `bar_area_width', respectively.
19177 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19178 background extension.
19180 2011-05-10 Jim Meyering <meyering@redhat.com>
19182 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19184 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19186 * image.c (Finit_image_library): Return t for built-in image types,
19187 like pbm and xbm. (Bug#8640)
19189 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19191 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19193 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19195 * w32console.c (Fset_screen_color): Doc fix.
19196 (Fget_screen_color): New function.
19197 (syms_of_ntterm): Defsubr it.
19199 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19200 unlink the temporary file if Fcall_process didn't create it in the
19202 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19203 child process will be redirected to a file specified with `:file'.
19204 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19205 cue to call_process_cleanup not to close that handle.
19207 2011-05-07 Ben Key <bkey76@gmail.com>
19209 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19210 one of two shell specific rules, either bootstrap-temacs-CMD or
19211 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19212 to the previous implementation of the bootstrap-temacs rule.
19213 The bootstrap-temacs-CMD rule is similar to the previous
19214 implementation of the bootstrap-temacs rule except that it
19215 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19218 These changes, along with some changes to nt/configure.bat,
19219 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19220 earlier fix to add support for --cflags and --ldflags options
19221 that include quotes so that it works whether make uses cmd or
19224 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19226 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19227 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19229 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19230 a string. Handle both cases.
19231 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19232 (Fdbus_register_method): Use Qinvalid_function.
19234 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19236 * makefile.w32-in: Update dependencies.
19237 (LISP_H): Add inttypes.h and stdin.h.
19238 (PROCESS_H): Add unistd.h.
19240 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19242 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19243 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19245 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19247 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19249 * term.c (vfatal): Remove stray call to va_end.
19250 It's not needed and the C Standard doesn't allow it here anyway.
19252 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19253 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19255 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19258 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19260 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19262 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19264 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19266 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19268 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19269 * charset.c (Fdefine_charset_internal): Don't initialize
19270 charset.code_space[15]. The value was garbage, on hosts with
19271 32-bit int (Bug#8600).
19273 * lread.c (read_integer): Be more consistent with string-to-number.
19274 Use string_to_number to do the actual conversion; this avoids
19275 rounding errors and fixes some other screwups. Without this fix,
19276 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19277 (digit_to_number): Move earlier, for benefit of read_integer.
19278 Return -1 if the digit is out of range for the base, -2 if it is
19279 not a digit in any supported base. (Bug#8602)
19281 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19283 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19284 to match comment at start of function. This also removes a
19285 GCC warning about overflow in a 32+64-bit port.
19287 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19289 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19290 Reported by Stefan Monnier in
19291 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19292 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19293 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19295 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19296 (EMACS_UINTPTR): Likewise, with uintptr_t.
19298 * lisp.h: Prefer 64-bit EMACS_INT if available.
19299 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19300 on 32-bit hosts that have 64-bit int, so that they can access
19302 However, temporarily disable this change unless the temporary
19303 symbol WIDE_EMACS_INT is defined.
19305 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19307 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19308 This removes an assumption that EMACS_INT and long are the same
19309 width as pointers. The assumption is true for Emacs porting targets
19310 now, but we want to make other targets possible.
19311 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19312 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19313 In the rest of the code, change types of integers that hold casted
19314 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19315 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19316 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19317 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19318 No need to cast type when ORing.
19319 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19320 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19321 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19322 assume EMACS_INT is the same width as char *.
19323 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19324 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19325 Remove no-longer-needed casts.
19326 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19327 (xg_tool_bar_help_callback, xg_make_tool_item):
19328 Use EMACS_INTPTR to hold an integer
19329 that will be cast to void *; this can avoid a GCC warning
19330 if EMACS_INT is not the same width as void *.
19331 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19332 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19333 (current_message_1, set_message_1):
19334 Use a local to convert to proper width without a cast.
19335 * xmenu.c (dialog_selection_callback): Likewise.
19337 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19338 Also, don't assume VALBITS / RAND_BITS is less than 5,
19339 and don't rely on undefined behavior when shifting a 1 left into
19341 * lisp.h (get_random): Change signature to match.
19343 * lread.c (hash_string): Use size_t, not int, for hash computation.
19344 Normally we prefer signed values; but hashing is special, because
19345 it's better to use unsigned division on hash table sizes so that
19346 the remainder is nonnegative. Also, size_t is the natural width
19347 for hashing into memory. The previous code used 'int', which doesn't
19348 retain enough info to hash well into very large tables.
19349 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19351 * dbusbind.c: Don't possibly lose pointer info when converting.
19352 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19353 Use XPNTR rather than XHASH, so that the high-order bits of
19354 the pointer aren't lost when converting through void *.
19356 * eval.c (Fautoload): Don't double-shift a pointer.
19358 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19360 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19362 * gnutls.c (DEF_GNUTLS_FN):
19363 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19365 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19367 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19370 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19372 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19373 New version that can reserve upto 2GB of heap space.
19375 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19377 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19379 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19381 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19382 `gnutls_certificate_set_x509_key_file'.
19384 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19386 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19387 Update dependencies.
19389 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19391 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19392 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19393 Remove unused parameter `fildes'.
19394 * process.c (read_process_output, send_process): Don't pass it.
19396 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19398 Fix previous change: the library cache is defined in w32.c.
19399 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19400 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19402 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19404 Implement dynamic loading of GnuTLS on Windows.
19406 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19407 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19408 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19411 * gnutls.c (Qgnutls_dll): Define.
19412 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19413 (gnutls_*): Declare function pointers.
19414 (init_gnutls_functions): New function to initialize function pointers.
19415 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19416 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19417 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19418 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19419 (emacs_gnutls_write, emacs_gnutls_read)
19420 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19421 (Fgnutls_available_p): New function.
19422 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19423 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19424 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19426 * image.c: Include w32.h.
19427 (Vimage_type_cache): Delete.
19428 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19429 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19430 (w32_delayed_load): Move to w32.c.
19432 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19434 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19435 (w32_delayed_load): Move from image.c. When loading a library, record
19436 its filename in the :loaded-from property of the library id.
19437 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19438 Initialize and staticpro them.
19439 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19441 * process.c: Include lisp.h before w32.h, not after.
19442 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19443 instead of gnutls_record_check_pending.
19445 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19447 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19449 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19450 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19453 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19455 * xterm.c (x_set_frame_alpha): Do not set property on anything
19456 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19458 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19460 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19462 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19464 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19465 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
19466 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

19471 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19472 (Qgnutls_bootprop_callbacks_verify): Make static.
19474 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19476 * callproc.c: Indentation fixup.
19478 * sysdep.c (wait_for_termination_1): Make static.
19479 (wait_for_termination, interruptible_wait_for_termination):
19480 Move after wait_for_termination_1.
19482 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19484 * sysdep.c (interruptible_wait_for_termination): New function
19485 which is like wait_for_termination, but allows keyboard
19488 * callproc.c (Fcall_process): Add (:file "file") as an option for
19490 (Fcall_process_region): Ditto.
19492 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19494 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19495 rather than `XVECTOR (FOO)->size'.
19497 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19498 inttypes.h, as a gnulib replacement is used if it not available in
19501 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19503 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19504 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19505 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19507 * coding.c (coding_alloc_by_realloc): Error out if destination
19508 will grow beyond MOST_POSITIVE_FIXNUM.
19509 (decode_coding_emacs_mule): Abort if there isn't enough place in
19510 charbuf for the composition carryover bytes. Reserve an extra
19511 space for up to 2 characters produced in a loop.
19512 (decode_coding_iso_2022): Abort if there isn't enough place in
19513 charbuf for the composition carryover bytes.
19515 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19517 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19518 aborting when %lld or %lll format is passed.
19519 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19520 %llo or %llx format is passed. (Bug#8545)
19522 * window.c (window_scroll_line_based): Use a marker instead of
19523 simple variables to record original value of point. (Bug#7952)
19525 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19526 produced by %s or %c overflows available buffer space. (Bug#8545)
19528 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19530 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19531 (SIZE_MAX): Move defn after all includes, as they might #define it.
19533 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19535 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19537 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19539 * keyboard.c (Qdelayed_warnings_hook): Define.
19540 (command_loop_1): Run `delayed-warnings-hook'
19541 if Vdelayed_warnings_list is non-nil.
19542 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19543 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19545 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19547 * doprnt.c (doprnt): Don't return value smaller than the buffer
19548 size if the message was truncated. (Bug#8545).
19550 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19552 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19553 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19555 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19557 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19559 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19561 * makefile.w32-in: Update dependencies.
19563 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19565 Improve `doprnt' and its usage. (Bug#8545)
19566 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19567 `format_end'. Remove support for %l as a conversion specifier.
19568 Don't use xrealloc. Improve diagnostics when the %l size modifier
19569 is used. Update the commentary.
19571 * eval.c (verror): Simplify calculation of size_t.
19573 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19576 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19578 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19581 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19583 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19584 This makes this file independent of the recent pseudovector change.
19586 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19588 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19590 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19591 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19592 Remove unused local.
19593 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19595 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19596 GCC 4.6.0 optimizes based on type-based alias analysis.
19597 For example, if b is of type struct buffer * and v of type struct
19598 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19599 != &v->size, and therefore "v->size = 1; b->size = 2; return
19600 v->size;" must therefore return 1. This assumption is incorrect
19601 for Emacs, since it type-puns struct Lisp_Vector * with many other
19602 types. To fix this problem, this patch adds a new type struct
19603 vectorlike_header that documents the constraints on layout of vectors
19604 and pseudovectors, and helps optimizing compilers not get fooled
19605 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19606 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19607 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19609 (XSETPVECTYPE): Rewrite in terms of new macro.
19610 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19611 This is a bit clearer, and further avoids the possibility of
19612 undesirable aliasing.
19613 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19614 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19615 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19616 since Lisp_Subr is a special case (no "next" field).
19617 (ASIZE): Now uses header.size rather than size.
19618 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19619 to avoid the hassle of writing XVECTOR (foo)->header.size.
19620 (struct vectorlike_header): New type.
19621 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19622 object, to help avoid aliasing.
19623 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19624 (SUBRP): Likewise, since Lisp_Subr is a special case.
19625 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19626 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19627 (struct Lisp_Hash_Table): Combine first two members into a single
19628 struct vectorlike_header member. All uses of "size" and "next" members
19629 changed to be "header.size" and "header.next".
19630 * buffer.h (struct buffer): Likewise.
19631 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19632 * frame.h (struct frame): Likewise.
19633 * process.h (struct Lisp_Process): Likewise.
19634 * termhooks.h (struct terminal): Likewise.
19635 * window.c (struct save_window_data, struct saved_window): Likewise.
19636 * window.h (struct window): Likewise.
19637 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19638 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19639 * buffer.c (init_buffer_once): Likewise.
19640 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19642 * process.c (Fformat_network_address): Use local var for size,
19645 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19647 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19648 * data.c (atof): Remove decl; no longer used or needed.
19649 (digit_to_number): Move to lread.c.
19650 (Fstring_to_number): Use new string_to_number function, to be
19651 consistent with how the Lisp reader treats infinities and NaNs.
19652 Do not assume that floating-point numbers represent EMACS_INT
19653 without losing information; this is not true on most 64-bit hosts.
19654 Avoid double-rounding errors, by insisting on integers when
19655 parsing non-base-10 numbers, as the documentation specifies.
19656 * lisp.h (string_to_number): New decl, replacing ...
19657 (isfloat_string): Remove.
19658 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19659 (read1): Do not accept +. and -. as integers; this
19660 appears to have been a coding error. Similarly, do not accept
19661 strings like +-1e0 as floating point numbers. Do not report
19662 overflow for integer overflows unless the base is not 10 which
19663 means we have no simple and reliable way to continue.
19664 Break out the floating-point parsing into a new
19665 function string_to_number, so that Fstring_to_number parses
19666 floating point numbers consistently with the Lisp reader.
19667 (digit_to_number): Move here from data.c. Make it static inline.
19668 (E_CHAR, EXP_INT): Remove, replacing with ...
19669 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19670 (string_to_number): New function, replacing isfloat_string.
19671 This function checks for valid syntax and produces the resulting
19672 Lisp float number too. Rework it so that string-to-number
19673 no longer mishandles examples like "1.0e+". Use strtoumax,
19674 so that overflow for non-base-10 numbers is reported only when
19675 there's no portable and simple way to convert to floating point.
19677 * textprop.c (set_text_properties_1): Rewrite for clarity,
19678 and to avoid GCC warning about integer overflow.
19680 * intervals.h (struct interval): Use EMACS_INT for members
19681 where EMACS_UINT might cause problems. See
19682 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19683 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19684 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19686 (offset_intervals): Tell GCC not to worry about length overflow
19687 when negating a negative length.
19689 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19690 (overrun_check_free): Likewise.
19692 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19693 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19696 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19697 (gnutls_make_error): Rename local to avoid shadowing.
19698 (gnutls_emacs_global_deinit): ifdef out; not used.
19699 (Fgnutls_boot): Use const for pointer to readonly storage.
19700 Comment out unused local. Fix pointer signedness problems.
19702 * lread.c (openp): Don't stuff size_t into an 'int'.
19703 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19704 about possible signed overflow.
19706 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19707 (GDK_KEY_g): Don't define if already defined.
19708 (xg_prepare_tooltip): Avoid pointer signedness problem.
19709 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19711 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19712 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19714 * xfns.c (Fx_window_property): Simplify a bit,
19715 to make a bit faster and to avoid GCC 4.6.0 warning.
19716 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19718 * fns.c (internal_equal): Don't assume size_t fits in int.
19720 * alloc.c (compact_small_strings): Tighten assertion a little.
19722 Replace pEd with more-general pI, and fix some printf arg casts.
19723 * lisp.h (pI): New macro, generalizing old pEd macro to other
19724 conversion specifiers. For example, use "...%"pI"d..." rather
19725 than "...%"pEd"...".
19726 (pEd): Remove. All uses replaced with similar uses of pI.
19727 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19728 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19729 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19730 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19731 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19732 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19733 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19735 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19736 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19737 * print.c (safe_debug_print, print_object): Likewise.
19738 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19740 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19741 avoiding the 0 flag, which is not portable.
19742 * process.c (Fmake_network_process): Use pI to avoid cast.
19743 * region-cache.c (pp_cache): Likewise.
19744 * xdisp.c (decode_mode_spec): Likewise.
19745 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19746 behavior on 64-bit hosts with printf arg.
19747 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19748 (x_stop_queuing_selection_requests): Likewise.
19749 (x_get_window_property): Don't truncate byte count to an 'int'
19752 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19753 here, since it parses constructs like leading '-' and spaces,
19754 which are not wanted; and it overflows with large numbers.
19755 Instead, simply match F[0-9]+, which is what is wanted anyway.
19757 * alloc.c: Remove unportable assumptions about struct layout.
19758 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19759 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19760 (allocate_vectorlike, make_pure_vector): Use the new macros,
19761 plus offsetof, to remove unportable assumptions about struct layout.
19762 These assumptions hold on all porting targets that I know of, but
19763 they are not guaranteed, they're easy to remove, and removing them
19764 makes further changes easier.
19766 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19767 This doesn't fix a bug but makes the code clearer.
19768 (string_overrun_cookie): Now const. Use initializers that
19769 don't formally overflow signed char, to avoid warnings.
19770 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19771 can cause Emacs to crash when string overrun checking is enabled.
19772 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19773 multiple of sizeof (EMACS_INT); it need not be, if
19774 alignof(EMACS_INT) < sizeof (EMACS_INT).
19775 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19777 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19781 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19783 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19784 supposed to be handshaking. (Bug#8556)
19785 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19787 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19789 * lisp.h (Qdebug): List symbol.
19790 * eval.c (Qdebug): Restore global linkage.

19792 (handle_user_signal): Break into debugger when debug-on-event
19793 matches the current signal symbol.
19795 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19797 * alloc.c (check_sblock, check_string_bytes)
19798 (check_string_free_list): Convert to standard C.
19800 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19802 * w32.c (emacs_gnutls_push): Fix typo.
19804 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19806 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19807 "cast to pointer from integer of different size".
19809 Improve doprnt and its use in verror. (Bug#8545)
19810 * doprnt.c (doprnt): Document the set of format control sequences
19811 supported by the function. Use SAFE_ALLOCA instead of always
19814 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19815 is one byte too soon. Don't use xrealloc; instead xfree and
19818 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19820 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19823 * gnutls.c: Renamed global_initialized to
19824 gnutls_global_initialized. Added internals for the
19825 :verify-hostname-error, :verify-error, and :verify-flags
19826 parameters of `gnutls-boot' and documented those parameters in the
19827 docstring. Start callback support.
19828 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19829 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19830 on error. Return error code.
19831 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19832 (emacs_gnutls_read): Likewise.
19833 (Fgnutls_boot): Return handshake error code.

19897 <char-direction-table>: Deleted.
19899 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19901 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19902 * doprnt.c: Include limits.h.
19903 (SIZE_MAX): New macro.
19904 (doprnt): Return a size_t value. 2nd arg is now size_t.
19905 Many local variables are now size_t instead of int or unsigned.
19906 Improve overflow protection. Support `l' modifier for integer
19907 conversions. Support %l conversion. Don't assume an EMACS_INT
19908 argument for integer conversions and for %c.
19910 * lisp.h (doprnt): Restore prototype.
19912 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19913 $(SRC)/character.h.
19915 * Makefile.in (base_obj): Add back doprnt.o.
19917 * deps.mk (doprnt.o): Add back prerequisites.
19918 (callint.o): Depend on character.h.
19920 * eval.c (internal_lisp_condition_case): Include the handler
19921 representation in the error message.
19922 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19923 when breaking from the loop.
19925 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19927 * callint.c (Fcall_interactively): When displaying error message
19928 about invalid control letter, pass the character's codepoint, not
19929 a pointer to its multibyte form. Improve display of the character
19930 in octal and display also its hex code.
19932 * character.c (char_string): Use %x to display the (unsigned)
19933 codepoint of an invalid character, to avoid displaying a bogus
19936 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19937 `error', not SYMBOL_NAME itself.
19939 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19940 character arguments to `error'.
19942 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19943 to `error' in error message about FINAL_CHAR argument. Make sure
19944 FINAL_CHAR is a character, and use %c when it is passed as
19945 argument to `error'.
19947 2011-04-23 Eli Zaretskii <eliz@gnu.org>

20015 * dispextern.h (struct redisplay_interface): Rename param

20134 * nsfont.m: Fixed bugs in ns_get_family and
20135 ns_descriptor_to_entity that were caused by using free to
20136 deallocate memory blocks that were allocated by xmalloc (via
20137 xstrdup). This caused Emacs to crash when compiled with
20138 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20139 --enable-checking=xmallocoverrun). xfree is now used to
20140 deallocate these memory blocks.

20156 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
20157 (emacs_read, emacs_write): Use it.
20158 * process.c (send_process): Adjust to the new signatures of
20159 emacs_write and emacs_gnutls_write. Do not attempt to store

20488 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
20489 * lisp.h: Remove these decls.
20491 * buffer.c (buffer_count): Remove unused var.
20493 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20494 so that it's not optimized away.
20495 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20496 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20497 exported only to the debugger.
20499 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20500 * atimer.h (run_all_atimers): Remove; not exported.
20502 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20503 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20504 was inaccessible from Lisp.
20505 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20506 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20508 alloc.c: Import and export fewer symbols, and remove unused items.
20509 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20511 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20512 it's not optimized away by whole-program optimization.
20513 (message_enable_multibyte, free_misc): Remove.
20514 (catchlist, handlerlist, mark_backtrace):
20515 Declare only if BYTE_MARK_STACK.

20524 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20525 (mark_backtrace): Define only if BYTE_MARK_STACK.
20526 * xdisp.c (message_enable_multibyte): Now static.
20528 Declare Lisp_Object Q* variables to be 'static' if not exported.
20529 This makes it easier for human readers (and static analyzers)
20530 to see whether these variables are used from other modules.
20531 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20532 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20533 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

20541 Remove decls of unexported vars.
20542 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20544 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20546 Make Emacs functions such as Fatom 'static' by default.
20547 This makes it easier for human readers (and static analyzers)
20548 to see whether these functions can be called from other modules.
20549 DEFUN now defines a static function. To make the function external
20550 so that it can be used in other C modules, use the new macro DEFUE.
20551 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20552 (Finit_image_library):
20553 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20554 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20555 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20556 Remove decls, since these functions are now static.
20557 (Funintern, Fget_internal_run_time): New decls, since these functions
20558 were already external.
20560 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20561 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20567 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20568 Mark functions with DEFUE instead of DEFUN,
20569 if they are used in other modules.
20570 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20571 decls for now-static functions.
20572 * buffer.h (Fdelete_overlay): Remove decl.

20582 * image.c (Finit_image_library): New forward static decl.
20583 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20584 * intervals.h (Fprevious_property_change):
20585 (Fremove_list_of_text_properties): Remove decls.
20586 * keyboard.c (Fthis_command_keys): Remove decl.
20587 (Fcommand_execute): New forward static decl.

20605 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20608 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20610 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20611 when at ZV. (Bug#8487)
20613 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20615 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20618 * sound.c (sound_cleanup, alsa_close): Likewise.
20619 * termcap.c (tgetent): Likewise.
20620 * xfns.c (x_default_font_parameter): Likewise.
20621 * xsettings.c (read_and_apply_settings): Likewise.
20623 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20624 (overrun_check_free): Protoize.
20626 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20628 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20629 since callers should never pass a negative size.
20630 Change the signature to match that of plain 'read' and 'write'; see
20631 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20632 * lisp.h: Update prototypes of emacs_write and emacs_read.
20634 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20636 * xdisp.c (redisplay_window): Don't try to determine the character
20637 position of the scroll margin if the window start point w->startp
20638 is outside the buffer's accessible region. (Bug#8468)
20640 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20642 Fix write-region and its subroutines for buffers > 2GB.
20643 * fileio.c (a_write, e_write): Modify declaration of arguments and
20644 local variables to support buffers larger than 2GB.
20645 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20647 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20648 argument, local variables, and return value.
20650 * lisp.h: Update prototypes of emacs_write and emacs_read.
20652 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20654 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20656 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20658 Fix more problems found by GCC 4.6.0's static checks.
20660 * xdisp.c (vmessage): Use a better test for character truncation.
20662 * charset.c (load_charset_map): <, not <=, for optimization,
20663 and to avoid potential problems with integer overflow.
20664 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20665 * casetab.c (set_identity, shuffle): Likewise.
20666 * editfns.c (Fformat): Likewise.
20667 * syntax.c (skip_chars): Likewise.
20669 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20670 This also lets GCC 4.6.0 generate slightly better loop code.
20672 * callint.c (Fcall_interactively): <, not <=, for optimization.
20673 (Fcall_interactively): Count the number of arguments produced,
20674 not the number of arguments given. This is simpler and lets GCC
20675 4.6.0 generate slightly better code.
20677 * ftfont.c: Distingish more carefully between FcChar8 and char.
20678 The previous code passed unsigned char * to a functions like
20679 strlen and xstrcasecmp that expect char *, which does not
20680 conform to the C standard.
20681 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20682 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20683 char * when the C standard requires it.
20685 * keyboard.c (read_char): Remove unused var.
20687 * eval.c: Port to Windows vsnprintf (Bug#8435).
20688 Include <limits.h>.
20689 (SIZE_MAX): Define if the headers do not.
20690 (verror): Do not give up if vsnprintf returns a negative count.
20691 Instead, grow the buffer. This ports to Windows vsnprintf, which
20692 does not conform to C99. Problem reported by Eli Zaretskii.
20693 Also, simplify the allocation scheme, by avoiding the need for
20694 calling realloc, and removing the ALLOCATED variable.
20696 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20698 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20699 But keep the doprint source code for now, as we might revamp it
20700 and use it again (Bug#8435).
20701 * lisp.h (doprnt): Remove.
20702 * Makefile.in (base_obj): Remove doprnt.o.
20703 * deps.mk (doprnt.o): Remove.
20705 error: Print 32- and 64-bit integers portably (Bug#8435).
20706 Without this change, on typical 64-bit hosts error ("...%d...", N)
20707 was used to print both 32- and 64-bit integers N, which relied on
20708 undefined behavior.
20709 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20710 * lisp.h (error, verror): Mark as printf-like functions.
20711 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20712 Report overflow in size calculations when allocating printf buffer.
20713 Do not truncate output string at its first null byte.
20714 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20715 Truncate the output at a character boundary, since vsnprintf does not
20717 * charset.c (check_iso_charset_parameter): Convert internal
20718 character to string before calling 'error', since %c now has the
20720 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20721 overflow when computing char to be passed to 'error'. Do not
20722 pass Lisp_Object to 'error'; pass the integer instead.
20723 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20724 formatted with plain %d.
20726 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20728 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20730 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20732 * xterm.c (x_catch_errors): Remove duplicate declaration.
20734 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20736 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20738 2011-04-10 Jim Meyering <meyering@redhat.com>
20740 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20741 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20742 return ssize_t not "int", and use size_t as the buffer length.
20743 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20744 * gnutls.h: Update declarations.
20745 * process.c (read_process_output): Use ssize_t, to match.
20746 (send_process): Likewise.
20748 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20750 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20752 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20754 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20755 Use unsigned char, to match FcChar8 type definition.
20757 * xterm.c (handle_one_xevent):
20758 * xmenu.c (create_and_show_popup_menu):
20759 * xselect.c (x_decline_selection_request)
20760 (x_reply_selection_request): Avoid type-punned deref of X events.
20762 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20764 Fix some uses of `int' instead of EMACS_INT.
20765 * search.c (string_match_1, fast_string_match)
20766 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20767 (scan_buffer, find_next_newline_no_quit)
20768 (find_before_next_newline, search_command, Freplace_match)
20769 (Fmatch_data): Make some `int' variables be EMACS_INT.
20771 * xdisp.c (display_count_lines): 3rd argument and return value now
20772 EMACS_INT. All callers changed.
20773 (pint2hrstr): Last argument is now EMACS_INT.
20775 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20776 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20777 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20788 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20789 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20791 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20792 (encode_invocation_designation): Last argument P_NCHARS is now
20794 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20795 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20797 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20800 * ccl.c (Fccl_execute_on_string): Declare some variables
20803 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20805 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20807 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20809 * process.c (Fformat_network_address): Doc fix.
20811 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20813 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20815 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20817 * keyboard.c (read_char): Call Lisp function help-form-show,
20818 instead of using internal_with_output_to_temp_buffer.
20819 (Qhelp_form_show): New var.
20820 (syms_of_keyboard): Use DEFSYM macro.
20822 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20829 (list_processes_1): Delete.
20831 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20833 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20835 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20837 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20839 Fix more problems found by GCC 4.6.0's static checks.

20854 printf-like functions.
20855 (tiff_load): Add casts to remove these marks before passing them
20856 to system-supplied API.
20858 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20860 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20861 This avoids several warnings with gcc -Wstrict-overflow.
20862 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20863 directly, rather than having caller test rule sign. This avoids
20864 some unnecessary tests.
20865 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20866 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20867 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20869 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20870 (xfont_open): Avoid unnecessary tests.
20872 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20874 * composite.h, composite.c (composition_gstring_put_cache):
20875 Use EMACS_INT, not int, for length.
20877 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20878 breaking out part of COMPOSITION_DECODE_RULE.
20879 (COMPOSITION_DECODE_RULE): Use it.
20880 * composite.c (get_composition_id): Remove unused local vars,
20881 by using the new macro.
20883 * textprop.c (set_text_properties_1): Change while to do-while,
20884 since the condition is always true at first.
20886 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20887 (interval_deletion_adjustment): Return unsigned value.
20890 * process.c (list_processes_1, create_pty, read_process_output):
20891 (exec_sentinel): Remove vars that were set but not used.
20892 (create_pty): Remove unnecessary "volatile"s.
20893 (Fnetwork_interface_info): Avoid possibility of int overflow.
20894 (read_process_output): Do adaptive read buffering even if carryover.
20895 (read_process_output): Simplify nbytes computation if buffered.

20899 * syntax.c (scan_words): Remove var that was set but not used.
20900 (update_syntax_table): Use unsigned instead of int.
20902 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20903 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20904 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20906 * print.c (print_error_message): Avoid int overflow.
20908 * font.c (font_list_entities): Redo for clarity,
20909 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20911 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20912 (font_score): Avoid potential overflow in diff calculation.
20914 * fns.c (substring_both): Remove var that is set but not used.
20915 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20917 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20919 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20920 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20921 can always succeed if overflow has undefined behavior.
20923 * search.c (boyer_moore, wordify): Remove vars set but not used.
20924 (wordify): Omit three unnecessary tests.
20926 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20927 All callers changed. This avoids the need for an unused var.
20929 * casefiddle.c (casify_region): Remove var that is set but not used.
20931 * dired.c (file_name_completion): Remove var that is set but not used.
20933 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20935 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20936 (Finsert_file_contents): Remove unnecessary code checking fd.
20938 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20939 Check for integer overflow on size calculations.
20941 * buffer.c (Fprevious_overlay_change): Remove var that is set
20944 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20945 Remove vars that are set but not used.
20946 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20947 (timer_check_2): Mark vars as initialized.
20949 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20951 * image.c (lookup_image): Remove var that is set but not used.
20952 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20954 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20955 that are set but not used.
20957 * xfns.c (make_invisible_cursor): Don't return garbage
20958 if XCreateBitmapFromData fails (Bug#8410).
20960 * xselect.c (x_get_local_selection, x_handle_property_notify):
20961 Remove vars that are set but not used.
20963 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20964 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20966 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20967 Remove var that is set but not used.
20968 (scroll_bar_windows_size): Now size_t, not int.
20969 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20970 Check for overflow.
20972 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20973 (map_tty_color) [!defined MSDOS]: Likewise.
20975 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20977 * coding.c: Remove vars that are set but not used.
20978 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20979 All callers changed.
20980 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20981 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20982 (decode_coding_charset): Remove vars that are set but not used.
20984 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20985 that is set but not used.
20987 * print.c (print_object): Remove var that is set but not used.
20989 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20990 The gnulib version avoids calling malloc in the usual case,
20991 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20992 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20993 * filelock.c (current_lock_owner): Likewise.
20994 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20995 * sysdep.c: Include allocator.h, careadlinkat.h.
20996 (emacs_no_realloc_allocator): New static constant.
20997 (emacs_readlink): New function.
20998 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20999 ../lib/careadlinkat.h.
21001 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21003 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21004 first non-nil return value).
21006 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21008 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21009 if not defined (Bug#8403).
21011 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21013 * xdisp.c (display_count_lines): Remove parameter `start',
21014 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21015 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21016 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21018 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21019 and thereabouts. All callers changed.
21020 (get_per_char_metric): Remove parameter `f', unused since
21021 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21023 2011-04-02 Jim Meyering <meyering@redhat.com>
21025 do not dereference NULL upon failed strdup
21026 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21027 (ns_get_family): Likewise.
21029 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21031 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21033 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21035 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21038 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21040 Add lexical binding.
21042 * window.c (Ftemp_output_buffer_show): New fun.
21043 (Fsave_window_excursion):
21044 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21046 * lread.c (lisp_file_lexically_bound_p): New function.
21047 (Fload): Bind Qlexical_binding.
21048 (readevalloop): Remove `evalfun' arg.
21049 Bind Qinternal_interpreter_environment.
21050 (Feval_buffer): Bind Qlexical_binding.
21051 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21053 (syms_of_lread): Declare `lexical-binding'.
21055 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21057 * keyboard.c (eval_dyn): New fun.
21058 (menu_item_eval_property): Use it.
21060 * image.c (parse_image_spec): Use Ffunctionp.
21062 * fns.c (concat, mapcar1): Accept byte-code-functions.
21064 * eval.c (Fsetq): Handle lexical vars.
21065 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21066 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21067 (FletX, Flet): Obey lexical binding.
21068 (Fcommandp): Handle closures.
21069 (Feval): New `lexical' arg.
21070 (eval_sub): New function extracted from Feval. Use it almost
21071 everywhere where Feval was used. Look up vars in lexical env.
21073 (Ffunctionp): Move from subr.el.
21074 (Ffuncall): Handle closures.
21075 (apply_lambda): Remove `eval_flags'.
21076 (funcall_lambda): Handle closures and new byte-code-functions.
21077 (Fspecial_variable_p): New function.
21078 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21079 but without exporting it to Lisp.
21081 * doc.c (Fdocumentation, store_function_docstring):
21082 * data.c (Finteractive_form): Handle closures.
21084 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21087 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21089 (exec_byte_code): New function extracted from Fbyte_code to handle new
21090 calling convention for byte-code-functions. Add new byte-codes.
21092 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21094 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21096 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21098 * xdisp.c (redisplay_internal): Fix prototype.
21100 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21102 * xdisp.c (SCROLL_LIMIT): New macro.
21103 (try_scrolling): Use it when setting scroll_limit.
21104 Limit scrolling to 100 screen lines.
21105 (redisplay_window): Even when falling back on "recentering",
21106 position point in the window according to scroll-conservatively,
21107 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21109 (try_scrolling): When point is above the window, allow searching
21110 as far as scroll_max, or one screenful, to compute vertical
21111 distance from PT to the scroll margin position. This prevents
21112 try_scrolling from unnecessarily failing when
21113 scroll-conservatively is set to a value slightly larger than the
21114 window height. Clean up the case of PT below the margin at bottom
21115 of window: scroll_max can no longer be INT_MAX. When aggressive
21116 scrolling is in use, don't let point enter the opposite scroll
21117 margin as result of the scroll.
21118 (syms_of_xdisp) <scroll-conservatively>: Document the
21119 threshold of 100 lines for never-recentering scrolling.
21121 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21123 * dispextern.h (move_it_by_lines):

21126 (message_log_check_duplicate): Remove parameters `prev_bol' and
21127 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21128 (redisplay_internal): Remove parameter `preserve_echo_area',
21129 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21131 * indent.c (Fvertical_motion):
21132 * window.c (window_scroll_pixel_based, Frecenter):
21133 Don't pass `need_y_p' to `move_it_by_lines'.
21135 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21137 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21138 steal a few bits to be more compact.
21139 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21140 Remove unneeded casts.
21142 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21144 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21146 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21147 binding" message (bug#7967).
21149 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21151 Fix more problems found by GCC 4.6.0's static checks.
21153 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21154 Remove unused local var.
21156 * editfns.c (Fmessage_box): Remove unused local var.
21158 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21159 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21160 Omit unused local vars.
21161 * window.c (shrink_windows): Omit unused local var.
21162 * menu.c (digest_single_submenu): Omit unused local var.
21163 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21164 Omit unused local var.
21166 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21167 Don't assume string length fits in int.
21168 (keyremap_step, read_key_sequence): Use size_t for sizes.
21169 (read_key_sequence): Don't check last_real_key_start redundantly.
21171 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21172 instead of alloca (Bug#8344).
21174 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21175 (Fbacktrace_frame): Don't assume nframes fits in int.
21177 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21182 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21184 * cm.c (calccost): Turn while-do into do-while, for clarity.
21186 * keyboard.c (syms_of_keyboard): Use the same style as later
21187 in this function when indexing through an array. This also
21188 works around GCC bug 48267.
21190 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21192 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21194 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21195 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21197 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21198 This avoids undefined behavior on integer overflow, and is a bit
21199 more convenient anyway since it is compared to a size_t variable.
21201 Variadic C functions now count arguments with size_t, not int.
21202 This avoids an unnecessary limitation on 64-bit machines, which
21203 caused (substring ...) to crash on large vectors (Bug#8344).
21204 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21205 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21213 * fns.c (concat): Likewise.
21214 * frame.c (x_set_frame_parameters): Likewise.
21215 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21216 0 if not found, not -1. All callers changed.
21218 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21219 (stack_copy_size): Now size_t, not int.
21220 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21222 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21224 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21225 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21226 All callers changed.
21228 * lisp.h (multibyte_char_to_unibyte):
21229 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21230 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21238 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21240 * keyboard.c (safe_run_hook_funcall): New function.
21241 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21242 don't set the hook to nil, but remove the offending function instead.
21243 (Qcommand_hook_internal): Remove, unused.
21244 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21245 Vcommand_hook_internal.
21247 * eval.c (enum run_hooks_condition): Remove.
21248 (funcall_nil, funcall_not): New functions.
21249 (run_hook_with_args): Call each function through a `funcall' argument.

21263 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21264 All callers changed.
21266 * w32.c (_wsa_errlist): Use braces for struct initializers.
21268 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21269 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21270 All callers changed.

21425 * buffer.c (Fkill_all_local_variables):
21426 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21428 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21429 unconditionally since it does the check itself.
21431 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21433 Fix more problems found by GCC 4.5.2's static checks.
21435 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21436 the first time through the loop, since we know p0 < p1 then.
21437 This also avoids a gcc -Wstrict-overflow warning.
21439 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21440 leading to a memory leak, possible in functions like
21441 load_charset_map_from_file that can allocate an unbounded number
21442 of objects (Bug#8318).
21444 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21445 that could (at least in theory) be that large.
21447 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21448 This is less likely to overflow, and avoids undefined behavior if
21449 overflow does occur. All callers changed. Use strtoul to scan
21450 for the unsigned long integer.
21451 (pint2hrstr): Simplify and tune code slightly.
21452 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21462 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21465 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21467 * process.c (Fmake_network_process): Use socklen_t, not int,
21468 where POSIX says socklen_t is required in portable programs.
21469 This fixes a porting bug on hosts like 64-bit HP-UX, where
21470 socklen_t is wider than int (Bug#8277).
21471 (Fmake_network_process, server_accept_connection):
21472 (wait_reading_process_output, read_process_output):
21475 * process.c: Rename or move locals to avoid shadowing.

21485 Make tparam.h and terminfo.c consistent.
21486 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21487 Include tparam.h instead, since it declares them.
21488 * cm.h (PC): Remove extern decl; tparam.h now does this.
21489 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21490 * terminfo.c: Include tparam.h, to check interfaces.
21491 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21492 (tparam): Adjust signature to match interface in tparam.h;
21493 this removes some undefined behavior. Check that outstring and len
21494 are zero, which they always are with Emacs.
21495 * tparam.h (PC, BC, UP): New extern decls.
21497 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21498 (xftfont_open): Rename locals to avoid shadowing.
21500 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

21512 * composite.c (composition_compute_stop_pos): Rename local to
21514 (composition_reseat_it): Remove unused locals.
21515 (find_automatic_composition, composition_adjust_point): Likewise.
21516 (composition_update_it): Mark var as initialized.
21517 (find_automatic_composition): Mark vars as initialized,
21518 with a FIXME (Bug#8290).

21522 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21523 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21524 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21525 to avoid shadowing.
21527 * textprop.c (property_change_between_p): Remove; unused.
21529 * intervals.c (interval_start_pos): Now static.
21531 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21537 Fix pointer signedness.
21538 (alsa_choose_format): Remove unused local var.
21539 (wav_play): Initialize a variable to 0, to prevent undefined
21540 behavior (Bug#8278).
21542 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21544 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21546 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21547 clobbering (Bug#8298).
21548 * sysdep.c (sys_subshell): Likewise.
21549 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21551 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21552 This should get cleaned up, so that child_setup has the
21553 same signature on all platforms.
21555 * callproc.c (call_process_cleanup): Now static.
21556 (relocate_fd): Rename locals to avoid shadowing.
21558 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21560 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21561 not to be necessary, and produces flickering.
21563 2011-03-20 Glenn Morris <rgm@gnu.org>
21565 * config.in: Remove file.
21567 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21569 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21570 are now in src/globals.h.
21571 (syms_of_minibuf): Remove spurious & from previous change.

21611 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
21612 Define only if needed.
21614 * unexelf.c (unexec): Name an expression,
21615 to avoid gcc -Wbad-function-cast warning.
21616 Use a different way to cause a compilation error if anyone uses
21617 n rather than nn, a way that does not involve shadowing.
21618 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21620 * deps.mk (unexalpha.o): Remove; unused.
21622 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21689 (Ftranslate_region_internal, Fformat):
21690 Rename or remove local vars to avoid shadowing.

21693 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
21696 * lisp.h (eassert): Check that the argument compiles, even if
21697 ENABLE_CHECKING is not defined.
21699 * data.c (Findirect_variable): Name an expression, to avoid
21700 gcc -Wbad-function-cast warning.

21717 (Fmemory_limit): Cast sbrk's returned value to char *.

21743 (RETALLOC_IF): Define only if needed.
21744 (WORDCHAR_P): Likewise. This one is never needed, but is used
21745 only in a comment talking about a compiler bug, so put inside
21746 the #if 0 of that comment.
21747 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21748 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21775 New macros, so that the caller can use some names other than
21776 gcpro1, gcpro2, etc.
21777 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21779 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21780 argument, for consistency with GCPRO2_VAR, etc: it is now the

21784 Rename locals to avoid shadowing.
21786 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

21788 dired.c's scmp function, had undefined behavior.
21789 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21790 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21791 * buffer.h: ... to here, because these macros use current_buffer,
21792 and the new implementation with inline functions needs to have
21793 current_buffer in scope now, rather than later when the macros
21795 (downcase, upcase1): New static inline functions.
21796 (DOWNCASE, UPCASE1): Reimplement using these functions.
21797 This avoids undefined behavior in expressions like
21798 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21799 from race conditions in accessing the global variables
21800 case_temp1 and case_temp2.
21801 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

21825 * marker.c (bytepos_to_charpos): Remove; unused.
21827 * lisp.h (verify_bytepos, count_markers): New decls,
21828 so that gcc does not warn that these functions aren't declared.

21831 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

21838 * buffer.c (fix_overlays_before): Mark locals as initialized.
21839 (fix_start_end_in_overlays): Likewise. This function should be
21840 simplified by using pointers-to-pointers, but that's a different

21843 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21844 (report_overlay_modification): Rename locals to avoid shadowing.

21849 to suppress a gcc -Wclobbered warning that does not seem to be right.
21850 (MAXPATHLEN): Define only if needed.
21852 * process.c (serial_open, serial_configure): Move decls from here ...
21853 * systty.h: ... to here, so that they can be checked.
21855 * fns.c (get_random, seed_random): Move extern decls from here ...
21856 * lisp.h: ... to here, so that they can be checked.
21858 * sysdep.c (reset_io): Now static.
21859 (wait_for_termination_signal): Remove; unused.
21861 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21867 (describe_map_tree):
21868 Rename locals to avoid shadowing.
