3 * w32term.c <input_signal_count>: Declare 'volatile'
4 unconditionally. (Bug#9066)
6 * w32.c (set_errno): Reset h_errno and don't set it to any other
7 value. Set errno instead.
8 (check_errno): Reset h_errno.
9 (sys_socket, socket_to_fd, sys_bind, sys_connect)
10 (sys_gethostname, sys_getservbyname, sys_getpeername)
11 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
12 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
14 (sys_gethostbyname): Set h_errno only errors detected.
16 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
18 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
20 2013-02-15 Eli Zaretskii <eliz@gnu.org>
22 * keyboard.c (read_char): Fix calculation of auto-save time out
23 when auto-save-timeout is less than 4. (Bug#13720)
25 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
26 time. Improve diagnostics in DebPrint. (Bug#13546)
28 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
29 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
30 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
31 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
32 make sure errno is set to an appropriate value. (Bug#13546)
33 (socket_to_fd): Add assertion against indexing fd_info[] with a
34 value that is out of bounds.
35 (sys_accept): If fd is negative, do not set up the child_process
36 structure for reading.
38 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
40 * composite.c (fill_gstring_header): Remove useless prototype.
42 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
43 * print.c (PRINTDECLARE, print_object):
44 * search.c (compile_pattern, fast_looking_at, search_buffer):
45 (simple_search, boyer_moore, Freplace_match):
46 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
47 (get_overlay_arrow_glyph_row, display_mode_element):
48 (decode_mode_spec_coding, message3):
49 * xfaces.c (face_at_string_position): Use bool for booleans.
52 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
54 Fix AIX port (Bug#13650).
55 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
56 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
57 was #undeffed earlier, so it cannot be used as a macro here.
58 Use the constant and not the macro.
60 2013-02-15 Eli Zaretskii <eliz@gnu.org>
62 * w32proc.c (new_child): If no vacant slots are found in
63 child_procs[], make another pass looking for slots whose process
64 has exited or died. (Bug#13546)
66 * w32.c (sys_pipe): When failing due to file descriptors above
67 MAXDESC, set errno to EMFILE.
68 (_sys_read_ahead): Update cp->status when failing to read serial
69 communications input, so that the status doesn't stay at
70 STATUS_READ_IN_PROGRESS. (Bug#13546)
72 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
74 * gtkutil.c (tb_size_cb): New function.
75 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
77 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
79 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
82 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
84 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
86 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
88 * font.c (font_range): Add pos_byte argument. Adjust comment
90 * font.h (font_range): Adjust prototype.
91 * composite.c (autocmp_chars): Pass byte position to font_range.
92 Break long line. Remove useless prototype and format comment.
94 2013-02-13 Glenn Morris <rgm@gnu.org>
96 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
98 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
100 Improve AIX port some more (Bug#13650).
101 With this, it should be as good as it was in 23.3, though it's
102 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
103 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
104 * unexaix.c (start_of_text): Remove.
105 (_data, _text): Declare as char[], not int, as AIX manual suggests.
106 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
107 (orig_load_scnptr, orig_data_scnptr):
108 Now off_t, not long, since they are file offsets.
109 (make_hdr): Use _data, not start_of_data ().
110 This is the key part of the fix.
111 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
112 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
114 * pre-crt0.c (data_start): Initialize to 1.
115 This ports to compilers that optimize the external declaration
116 'int x = 0;' as if it were 'int x;' to shrink the executable.
118 Improve AIX port (Bug#13650).
119 This doesn't fix the bug, but it makes progress: Emacs builds now.
120 * unexaix.c: Include inttypes.h, stdarg.h.
121 (report_error, report_error_1): Mark as _Noreturn.
122 (report_error): Don't report the wrong errno.
123 (report_error_1): Now varargs. All callers changed.
124 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
125 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
126 (write_ptr): Use %p to print address rather than %lx and a cast
127 to unsigned long. Grow buffer a bit, to be safer.
129 2013-02-13 Eli Zaretskii <eliz@gnu.org>
131 * bidi.c (bidi_resolve_neutral): After finding the next
132 non-neutral character, accept NEUTRAL_ON type as well, because
133 directional control characters, such as LRE and RLE, have their
134 type converted to that by bidi_resolve_weak. This avoids aborts
135 when LRE/RLE follows a run of neutrals.
136 (bidi_move_to_visually_next): Assert that return value of
137 bidi_peek_at_next_level is non-negative. Negative values will
140 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
142 Minor getenv-related fixes.
143 * callproc.c (Fcall_process_region) [!DOS_NT]:
144 Avoid unnecessary duplicate call to getenv.
145 * callproc.c (init_callproc):
146 * dispnew.c (init_display):
147 * sysdep.c (sys_subshell):
148 Omit unnecessary cast of getenv or egetenv.
150 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
152 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
155 2013-02-12 Eli Zaretskii <eliz@gnu.org>
157 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
159 (display_line): Set w->region_showing to the value of
160 it->region_beg_charpos, not to -1. This fixes redisplay
161 optimization when cursor is moved up after M->. (Bug#13623)
163 (try_scrolling): Scroll text up more if point is too close to ZV
164 and inside the scroll margin. This makes sure point is moved
165 outside the scroll margin in these cases.
167 * window.h (struct window): region_showing can no longer be
170 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
172 Tune by using memchr and memrchr.
173 * doc.c (Fsnarf_documentation):
174 * fileio.c (Fsubstitute_in_file_name):
175 * search.c (find_newline, scan_newline):
176 * xdisp.c (pos_visible_p, display_count_lines):
177 Use memchr and memrchr rather than scanning byte-by-byte.
178 * search.c (find_newline): Rename from scan_buffer.
179 Omit first arg TARGET, as it's always '\n'. All callers changed.
181 Clean up read_key_sequence a tiny bit more.
182 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
183 (read_key_sequence): Remove unused locals.
185 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
187 Clean up read_key_sequence a bit; reread active keymaps after first event.
188 * keyboard.c (read_char, read_char_x_menu_prompt)
189 (read_char_minibuf_menu_prompt):
190 Replace nmaps+maps with a single `map' arg.
191 (follow_key): Operate on a single map.
192 (active_maps): New function.
193 (test_undefined): Also return true for nil bindings.
194 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
195 a single (composed) keymap. Remember `first_event' to choose the right
196 set of active keymaps. Recompute the set of keymaps after receiving
197 the first event. Remove GOBBLE_FIRST_EVENT.
198 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
199 * keyboard.h (read_char): Update declaration.
200 * lread.c (read_filtered_event): Adjust call to read_char.
202 2013-02-11 Eli Zaretskii <eliz@gnu.org>
204 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
205 Don't use the limitation on backwards movement when lines are truncated
206 in the window. (Bug#13675)
208 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
210 * marker.c (set_marker_internal): If desired position is passed
211 as a marker, avoid call to buf_charpos_to_bytepos.
212 * window.c (Fset_window_point): Omit redundant type checking.
213 (Fset_window_start): Likewise. Format comment.
214 (window_scroll_pixel_based): Use set_marker_restricted_both
215 with character and byte positions obtained from an iterator.
216 (Fset_window_configuration): Use set_marker_restricted_both.
217 * xdisp.c (message_dolog): Likewise.
219 2013-02-10 Eli Zaretskii <eliz@gnu.org>
221 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
222 When text lines are longer than window's screen lines, don't move back
223 too far. This speeds up some redisplay operations. (Bug#13675)
225 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
227 * syntax.c (scan_sexps_forward): Fix byte position calculation
228 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
230 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
232 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
235 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
237 Minor hashing refactoring.
238 * fns.c (SXHASH_REDUCE): Move to lisp.h.
239 (sxhash_float): Return EMACS_UINT, for consistency with the other
241 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
242 non-static inline function and therefore can't use static vars.
243 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
244 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
245 with the other hash functions.
247 2013-02-09 Eli Zaretskii <eliz@gnu.org>
249 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
250 XXXXXX part of the temporary file pattern is not downcased even
251 when w32-downcase-file-names is non-nil. (Bug#13661)
253 * xdisp.c (decode_mode_spec): Remove handling of %t.
255 * msdos.c (careadlinkatcwd): Remove.
257 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
259 * lread.c (skip_dyn_bytes): New function (bug#12598).
260 (read1): Use it. Use getc instead of READCHAR to read bytes.
261 (load_each_byte): Remove. Update users.
263 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
265 * search.c (scan_buffer): Calculate end byte position just once.
266 (scan_newline): Do not recalculate start_byte.
267 (search_command): Use eassert.
268 * syntax.c (struct lisp_parse_state): New member location_byte.
269 (scan_sexps_forward): Record from_byte and avoid redundant
270 character to byte position calculation ...
271 (Fparse_partial_sexp): ... here. Break too long line.
273 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
275 * lisp.h (make_uninit_vector): New function.
276 * alloc.c (Fvector, Fmake_byte_code):
277 * ccl.c (Fregister_ccl_program):
278 * charset.c (Fdefine_charset_internal, define_charset_internal):
279 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
280 * composite.c (syms_of_composite):
281 * font.c (Fquery_font, Ffont_info, syms_of_font):

286 * syntax.c (init_syntax_once):
287 * w32unsubscribe.c (uniscribe_shape):
288 * window.c (Fcurrent_window_configuration):
289 * xfaces.c (Fx_family_fonts):
290 * xselect.c (selection_data_to_lisp_data): Use it.
292 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
294 * coding.c (Fdefine_coding_system_internal): Use AREF where
295 argument is known to be a vector.
296 * fns.c (Flocale_info): Likewise for ASET.
297 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
298 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
300 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
302 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
305 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
306 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
307 updateCollectionBehaviour.
309 * nsterm.m (NEW_STYLE_FS): Remove.
310 (ns_last_use_native_fullscreen): New variable.
311 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
312 (x_set_window_size): Do not take title bar and tool bar into account
313 if isFullscreen returns YES.
314 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
315 (check_native_fs): New function.
316 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
317 (ns_term_init): Remove NEW_STYLE_FS.
318 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
319 and tool bar if isFullscreen returns NO.
320 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
321 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
323 (window:willUseFullScreenPresentationOptions:): New method.
324 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
325 Hide toolbar if not enabled (Bug#13444).
326 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
327 Restore tool bar if enabled, hide it otherwise (Bug#13444).
328 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
329 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
330 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
331 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
332 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
333 (syms_of_nsterm): Add ns-use-native-fullscreen.
335 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
337 * fileio.c (Qchoose_write_coding_system): Now static.
339 2013-02-04 Eli Zaretskii <eliz@gnu.org>
341 * xdisp.c (window_buffer_changed): region_showing can be negative,
342 which still means region is being displayed.
343 (redisplay_internal): Resurrect code that forced redisplay of the
344 whole window when showing region and the mark has changed.
345 Record the new mark position to allow redisplay optimizations.
346 (display_line): If it->region_beg_charpos is non-zero, set the
347 window's region_showing member to -1. (Bug#13623) (Bug#13626)
349 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
350 not bitfield of 1 bit.
352 2013-02-03 Daniel Colascione <dancol@dancol.org>
354 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
355 daemon mode works on cygw32 when Emacs is installed and not just
358 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
360 Avoid file time stamp bug on MS-Windows (Bug#13149).
361 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
362 as FAT32 doesn't update time stamps when truncating them.
363 Also, check that a file time stamp is not a multiple of 100 ns;
364 this should catch all instances of the problem on MS-Windows,
365 as its native file system resolution is 100 ns or worse, and
366 checking for a non-multiple of 100 ns should impose only a small
367 overhead on systems with ns resolution.
369 2013-02-02 Eli Zaretskii <eliz@gnu.org>
371 Avoid encoding file names on MS-Windows when they need to be run
372 through dostounix_filename.
373 * w32.c (normalize_filename): Accept an additional argument
374 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
375 downcase it even if w32-downcase-file-names is non-nil.
376 (dostounix_filename): Accept an additional argument MULTIBYTE and
377 pass it to normalize_filename.
378 (emacs_root_dir): Adjust.
380 * msdos.h (dostounix_filename): Adjust prototype.
382 * w32.h (dostounix_filename): Adjust prototype.
384 * msdos.c (dostounix_filename): Accept an additional argument and
386 (init_environment): Adjust callers of dostounix_filename.
388 * fileio.c (Ffile_name_directory, file_name_as_directory)
389 (directory_file_name, Fexpand_file_name)
390 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
392 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
394 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
395 variables, as egetenv is case-insensitive for DOS_NT.
397 * dired.c (file_name_completion): Don't call Fdirectory_file_name
398 with an encoded file name.
400 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
401 Adjust calls to dostounix_filename.
403 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
405 * unexw32.c (unexec): Adjust call to dostounix_filename.
407 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
409 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
412 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
415 * callproc.c (Fcall_process): Make sure program name in PATH and
416 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
417 is passed to exec/spawnve, which fails unless the file-name
420 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
421 even if w32-quote-process-args is nil.
423 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
425 Fix timestamp bug when write-region appends nothing (Bug#13149).
426 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
427 the file's time stamp doesn't change if Emacs happens to write nothing
428 to the file, and on a buggy file system this could cause Emacs to
429 incorrectly infer that the file system doesn't have the bug.
430 Avoid this problem by inhibiting the inference in this case.
432 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
434 * window.h (struct window): Convert base_line_number, base_line_pos
435 and column_number_displayed members from Lisp_Object to ptrdiff_t.
436 Convert region_showing member from Lisp_Object to bitfield.
437 Remove sequence_number member. Adjust comments.
438 * window.c (sequence_number): Remove.
439 (make_window): Initialize column_number_displayed.
440 * print.c (print_object): Follow the printed representation of
441 frames and print window pointer to distinguish between windows.
442 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
443 * xdisp.c (wset_base_line_number, wset_base_line_pos)
444 (wset_column_number_displayed, wset_region_showing): Remove.
445 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
446 (try_scrolling, try_cursor_movement, redisplay_window)
447 (try_window_reusing_current_matrix, try_window_id, display_line)
448 (display_mode_lines, decode_mode_spec): Adjust users.
449 * .gdbinit (pwinx): Do not print sequence_number.
451 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
453 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
454 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
455 * dired.c: Include <fcntl.h>.
456 (open_directory): New function, which uses open and fdopendir
457 rather than opendir. DOS_NT platforms still use opendir, though.
458 (directory_files_internal, file_name_completion): Use it.
459 (file_attributes): New function, with most of the old Ffile_attributes.
460 (directory_files_internal, Ffile_attributes): Use it.
461 (file_attributes, file_name_completion_stat): First arg is now fd,
462 not dir name. All uses changed. Use fstatat rather than lstat +
464 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
465 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
466 (emacs_readlinkat): New function, with much of the old
467 Ffile_symlink_p, but with an fd argument for speed.
468 It uses readlinkat rather than careadlinkatcwd, so that it
469 need not assume the working directory.
470 (Ffile_symlink_p): Use it.
471 * filelock.c (current_lock_owner): Use emacs_readlinkat
472 rather than emacs_readlink.
473 * lisp.h (emacs_readlinkat): New decl.
474 (READLINK_BUFSIZE, emacs_readlink): Remove.
475 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
476 (emacs_norealloc_allocator, emacs_readlink): Remove.
477 This stuff is moved to fileio.c.
478 * w32.c (fstatat, readlinkat): New functions.
479 (careadlinkat): Don't check that fd == AT_FDCWD.
480 (careadlinkatcwd): Remove; no longer needed.

486 Move the last piece of choose_write_coding_system here. (Bug#13522)
487 (syms_of_fileio): Add choose-write-coding-system.
489 2013-01-30 Eli Zaretskii <eliz@gnu.org>
491 * w32.c (sys_open): Zero out the flags for the new file descriptor.
492 (sys_close): Zero out the flags for the file descriptor before
493 closing it. (Bug#13546)
495 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
496 (logon_network_drive, stat_worker, symlink, chase_symlinks):
497 Use CharNextExA and CharPrevExA to iterate over file names encoded in
500 * w32.c (w32_get_long_filename, init_environment, readlink):
501 Support file names encoded in DBCS codepages.
502 (readlink): Use the current file-name-coding-system, not the ANSI
503 codepage, to decode and handle targets of symlinks.
505 2013-01-28 Eli Zaretskii <eliz@gnu.org>
507 * w32.c (opendir): Now accepts a 'const char *'.
509 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
511 Remove obsolete redisplay code. See the discussion at
512 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
513 * dispnew.c (preemption_period, preemption_next_check): Remove.
514 (Vredisplay_preemption_period): Likewise.
515 (update_frame, update_single_window, update_window, update_frame_1):
516 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
517 used, following the 2012-06-22 change.
519 2013-01-25 Eli Zaretskii <eliz@gnu.org>
521 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
523 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
525 * font.c (num_fonts): Remove the leftover from old

533 * w32.c (max_filename_mbslen): New function.
534 (normalize_filename, readdir): Use it to detect locales where ANSI
535 encoding of file names uses a double-byte character set (DBCS).
536 If a DBCS encoding is used, advance by characters using
537 CharNextExA, instead of incrementing a 'char *' pointer.
538 Use _mbslwr instead of _strlwr. (Bug#13515)
540 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
541 request of memory reservation to 1.7GB. (Bug#13065)
543 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
545 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
546 at check_extra_latin label. (Bug#13505)
548 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
550 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
551 Avoid redundant calls to strlen.
553 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
555 Drop async_visible and async_iconified fields of struct frame.
556 This is possible because async input is gone; for details, see
557 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
558 * frame.h (struct frame): Remove async_visible and async_iconified
559 members, convert garbaged to unsigned bitfield. Adjust comments.
560 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
561 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
562 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
563 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
564 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
566 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
567 properly. Likewise for obscured.
569 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
572 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
574 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
576 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
577 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
579 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
581 * xdisp.c (message2, message2_nolog): Remove functions.
582 (message3, message3_nolog): Extract nbytes and multibyteness directly
583 from the string. Change all callers.
584 (message3_nolog): Don't set message_enable_multibyte since set_message
585 will reset it anyway.
586 (message1, message1_nolog): Use message3.
587 (vmessage): Use a stack allocated buffer rather than f->message_buf.
588 (with_echo_area_buffer): Remove last two arguments. Update all callers.
589 (set_message): Drop all but the second arg, which has to be a string.
590 (set_message_1): Simplify now that we know that a1 is NULL and the
591 second arg is a string.
592 * frame.h (struct frame): Remove `message_buf' field.
593 Use glyphs_initialized_p instead.
594 (FRAME_MESSAGE_BUF): Remove macro.
595 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
596 * lisp.h (message2, message2_nolog): Remove declarations.
597 (message3, message3_nolog): Update declarations.
598 * keyboard.c (read_char_minibuf_menu_text)
599 (read_char_minibuf_menu_width): Remove vars.
600 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
601 to correctly handle multibyte strings.
602 * frame.c (delete_frame): Don't free message_buf any more.
603 * editfns.c (message_text, message_length): Remove vars.
604 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
605 * fileio.c (auto_save_error): Use message3 instead of message2.
606 * dispnew.c (adjust_frame_message_buffer): Remove function.
608 2013-01-23 Eli Zaretskii <eliz@gnu.org>
610 * w32term.c (w32fullscreen_hook): Account correctly for the screen
611 real estate used for the tool bar and the menu bar.
613 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
615 * insdel.c (prepare_to_modify_buffer): Force redisplay if
616 hidden buffer is prepared to modification (Bug#13164).
618 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
620 * window.h (struct window): Change window_end_valid member from
621 Lisp_Object to a bitfield. Adjust comments.
622 (wset_window_end_valid): Remove.
623 * window.c (adjust_window_count): Clear window_end_valid.
624 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
625 (Fwindow_line_height, set_window_buffer, Frecenter)
626 (Fsplit_window_internal, Fdelete_other_windows_internal)
627 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
628 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
629 * xdisp.c (check_window_end, reconsider_clip_changes)
630 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
631 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
632 (find_first_unchanged_at_end_row, try_window_id): Likewise.
634 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
636 * xdisp.c (mark_window_display_accurate): Simplify the loop
637 assuming that the only one of vchild, hchild or buffer window
638 slots is non-nil. Call mark_window_display_accurate_1 for
639 the leaf windows only.
640 (mark_window_display_accurate_1): Always assume leaf window.
643 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
645 * emacs.c (Qkill_emacs_hook): Now static.
647 * fileio.c (Finsert_file_contents): Simplify.
648 Remove unnecessary assignments and tests.
650 2013-01-21 Eli Zaretskii <eliz@gnu.org>
652 * w32.c (acl_set_file): Don't test for errors unless
653 set_file_security returns FALSE. Avoids spurious errors when
656 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
658 * fileio.c (Finsert_file_contents): Revert code introduced at
659 2013-01-18 in favor of the simpler and generally better fix.
660 Save stack space by removing 'buffer' and reusing 'read_buf'
663 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
665 * lisp.h (eabs): Define unconditionally (Bug#13419).
666 The old "#if !defined (eabs)" was an unnecessary revenant of back
667 when this macro was called "abs". Document 'eabs' better.
669 2013-01-19 Glenn Morris <rgm@gnu.org>
671 * fns.c (Frandom): Doc fix.
673 2013-01-19 Eli Zaretskii <eliz@gnu.org>
675 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
676 segfault when there are lots of overlays.
678 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
679 when there are lots of overlays.
680 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
681 for the details and a way to reproduce.
683 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
685 * fileio.c: Use O_APPEND to append.
686 This corresponds better to the natural interpretation of "append",
687 and avoids the need to open the output file twice, or to invoke
688 lseek when APPEND is neither nil nor a number.
689 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
690 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
691 file possibly twice, and lseeking to its end; this avoids the
692 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
693 at the same time: the combination is never needed and apparently
694 it doesn't work with DOS_NT.
696 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
697 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
699 Allow floating-point file offsets.
700 Problem reported by Vitalie Spinu in
701 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
702 * fileio.c (emacs_lseek): Remove.
703 (file_offset): New function.
704 (Finsert_file_contents, Fwrite_region): Use it.
706 2013-01-19 Chong Yidong <cyd@gnu.org>
708 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
709 aborting on Fsignal (Bug#13289).
711 2013-01-19 Eli Zaretskii <eliz@gnu.org>
713 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
714 set_file_security as failure due to insufficient privileges.
715 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
716 (fstat): Return owner and group like 'stat' and 'lstat' do.
718 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
720 Work around bug in CIFS and vboxsf file systems (Bug#13149).
721 The bug was observed on Ubuntu operating inside a virtual machine,
722 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
723 The workaround introduces a race condition on non-buggy hosts,
724 but it's an unlikely race and anyway there's a nearly identical
725 nearby race that can't be fixed.
726 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
728 (Fwrite_region): Test for file system time stamp bug.
729 (init_fileio): New function.
730 * lisp.h (init_fileio): Declare it.
731 * emacs.c (main): Call it.
733 * fileio.c (Finsert_file_contents): Simplify new diagnostic
734 and make it more consistent with other stat-failure diagnostics.
736 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
738 Fix crash when inserting data from non-regular files.
739 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
740 for the error description produced by valgrind.
741 * fileio.c (read_non_regular): Rename to read_contents.
742 Free Lisp_Save_Value object used to pass parameters.
743 (read_non_regular_quit): Rename to read_contents_quit.
744 (Finsert_file_contents): Redesign internal file reading loop to adjust
745 gap and end positions after each read and so help make_gap to work
746 properly. Do not signal an I/O error too early and so do not leave
747 not yet decoded characters in a buffer, which was the reason of
748 redisplay crash. Use list2 to build return value. Adjust comments.
750 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
752 Close a race when statting and reading files (Bug#13149).
753 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
754 This avoids a race if the file is renamed between stat and open.
755 This race is not the problem originally noted in Bug#13149;
756 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
758 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

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

788 (map_keymap_char_table_item): Adjust accordingly.
789 * fileio.c (non_regular_fd, non_regular_inserted)
790 (non_regular_nbytes): Remove.
791 (Finsert_file_contents): Convert trytry to ptrdiff_t.
792 Use format_save_value to pass parameters to read_non_regular.
793 (read_non_regular): Use XSAVE_ macros to extract parameters.
795 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
797 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
799 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
801 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
802 extraction from any Lisp_Save_Value slot. Add type checking.
803 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
804 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
805 * xselect.c: All users changed.
807 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
809 Some convenient bits to deal with Lisp_Save_Values.
810 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
811 (allocate_misc): Remove prototype.
812 (format_save_value): New prototype.

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

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

872 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
874 Fix SIGDANGER handlers, for AIX (Bug#13408).
875 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
876 Move handlers here from emacs.c; they were out of place.
878 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
880 * xterm.c (syms_of_xterm): Adjust documentation for
881 scroll-bar-adjust-thumb-portion.
883 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
885 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
886 determine whether scroll bar thumb size should be adjusted or
887 not. Use variable for MOTIF.
889 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
892 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

901 (nsfont_open): Move block_input earlier. Add unblock_input before early
903 (nsfont_draw): Add block/unblock_input calls.
905 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
907 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
908 for old_charpos and old_bytepos.
910 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>

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

1027 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1028 Display the newline glyph more unambiguously.
1030 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1032 * nsterm.m (ns_draw_underwave):
1033 * w32term.c (w32_draw_underwave):
1034 * xterm.c (x_draw_underwave): Make underwave look more triangular

1037 * nsterm.m (ns_draw_text_decoration):
1038 * w32term.c (x_draw_glyph_string):
1039 * xterm.c (x_draw_glyph_string): Don't use previous underline
1040 thickness and position if previous underline type is underwave.

1060 * term.c (tty_ins_del_lines):
1061 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1062 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1064 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1066 * w32.c (unsetenv): Set up the string passed to _putenv
1068 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1069 for the bug this caused.
1071 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1073 * coding.c (Qmac): Now static.
1075 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1077 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1078 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1093 (xg_update_menubar): Update title only if
1094 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1095 (xg_update_submenu): Skip tearoff only if
1096 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1097 (xg_initialize): Initialize xg_detached_menus only if
1098 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1100 * xterm.h (struct x_output): Surround handlebox_widget with
1101 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1102 toolbar_in_hbox is bool.
1104 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>

1125 SetEvent and WaitForSingleObject.
1127 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1129 Port EXTERNALLY_VISIBLE to Clang 3.2.
1130 * conf_post.h (__has_attribute): New macro.
1131 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1133 2012-12-27 Glenn Morris <rgm@gnu.org>
1135 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1136 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1138 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1140 * fileio.c (file_name_as_directory, directory_file_name):
1141 Accept an additional argument MULTIBYTE to indicate whether the input C
1142 came from a multibyte or a unibyte Lisp string; all callers
1143 adjusted. Don't assume the input string is always multibyte.
1145 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1146 don't ENCODE_FILE them, and return a unibyte string if the input
1148 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1149 don't assume the input strings will always be multibyte. If the
1150 input strings are multibyte, decode strings obtained from C
1153 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1155 * lisp.h (toplevel): Add two notices to the comment about
1156 defining a new Lisp data type.

1160 * alloc.c (valid_lisp_object_p): Adjust comment.
1162 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1164 * keyboard.c (record_asynch_buffer_change): Initialize an event
1165 only if it's really needed.
1166 * frame.h (enum output_method): Remove output_mac member since
1167 it's a leftover from the deleted code.
1168 * frame.c (Fframep): Adjust user here ...
1169 * terminal.c (Fterminal_live_p): ... and here.
1170 * coding.c (Qmac): Now here because it's only used to denote
1171 end-of-line encoding type.
1172 (syms_of_coding): DEFSYM it.
1173 * frame.h (Qmac): Remove duplicated declaration.
1175 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1177 * window.c (select_window_1): Now static, since it's used only here.
1179 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1181 * window.c (window_body_cols): Subtract display margins from the
1182 window body width on TTYs as well. See
1183 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1184 for the original report.
1186 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1188 * xdisp.c (redisplay_window): Remove inner local variable
1189 because the outer shadowed one has the same meaning.
1190 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1192 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1193 (xg_create_tool_bar): Adjust users.
1195 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1197 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1198 * buffer.c (Fget_buffer_create): Use it to set compact field of
1199 struct buffer_text to avoid accessing an uninitialized value
1200 when compact_buffer is called for the first time.
1201 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1202 (Fset_buffer_modified_p): Use buffer_window_count to check
1203 whether the buffer is displayed in some window.
1204 * xdisp.c (message_dolog): Likewise.
1206 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1208 * w32.c (acl_set_file): If setting the file security descriptor
1209 fails, and the new DACL is identical to the existing one, silently
1210 return success. This fixes problems for users backing up their
1211 own files without having the necessary privileges for setting
1212 security descriptors.
1214 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1216 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1217 after WaitForSingleObject returns normally. This expedites reader
1218 thread shutdown when delete_child triggers it.
1219 (reap_subprocess): More accurate commentary for why we call
1220 delete_child only when cp->fd is negative.
1222 * w32.c (sys_close): Do not call delete_child on a subprocess
1223 whose handle is not yet closed. Instead, set its file descriptor
1224 to a negative value, so that reap_subprocess will call
1225 delete_child on that subprocess when its SIGCHLD arrives.
1226 This avoids closing handles used for communications between sys_select
1227 and reader_thread, which doesn't give sys_select a chance to
1228 notice that the process exited and invoke the SIGCHLD handler for
1231 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1233 * nsfns.m (Fns_do_applescript): Run event loop until script has
1234 been executed (Bug#12969).
1235 (ns_run_ascript): Chech as_script for nil, set to nil after

1242 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1244 * w32term.c (w32fullscreen_hook): New function.
1245 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1247 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1249 * fileio.c (Finsert_file_contents): Doc fix.
1251 * w32proc.c (new_child, delete_child, find_child_pid): For a
1252 subprocess, consider its slot being in use as long as its process
1253 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1254 slot when a new process is started immediately after killing
1255 another one, without waiting enough time for the first process to
1256 be reaped and resources allocated for it be orderly freed.
1258 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1260 2012-12-21 Chong Yidong <cyd@gnu.org>
1262 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1264 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1266 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1268 * w32.c (get_name_and_id): Always pass NULL as the first argument
1269 of lookup_account_sid. Avoids crashes with UNC file names that
1270 refer to DFS domains, not to specific machine names. (Bug#12621)
1271 Remove now unused argument FNAME; all callers changed.
1272 (get_file_owner_and_group): Remove now unused argument FNAME; all
1275 2012-12-21 Chong Yidong <cyd@gnu.org>
1277 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1278 error for invalid chars, don't check for a nil return value.
1280 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1282 Avoid calls to CHAR_TO_BYTE if byte position is known.
1283 * editfns.c (make_buffer_string_both): Use move_gap_both.
1284 (Fbuffer_string): Use make_buffer_string_both.

1288 (charpos_to_bytepos): Remove.
1289 * fileio.c (Finsert_file_contents): Use move_gap_both.
1290 * search.c (Freplace_match): Likewise.
1291 * process.c (process_send_region): Likewise. Use convenient
1292 names for byte positions.
1293 * lisp.h (charpos_to_bytepos): Remove prototype.
1294 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1295 * insdel.c (move_gap): Likewise.

1303 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1304 (redisplay_internal): Don't bother selecting the frame to get the
1305 proper value of frame-local variables (bug#13225).
1307 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1309 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1310 Rename 4th argument since it may be buffer or string. Adjust comment.
1311 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1313 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1315 * coding.c (Fdetect_coding_region): Do not check start and end with
1316 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1317 (code_convert_region): Likewise.
1319 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1321 * w32.c (acl_get_file, acl_set_file): Run the file name through
1322 map_w32_filename, and resolve any symlinks in the file name, like
1324 (acl_set_file): Call revert_to_self, if any privileges were

1330 ($(BLD)/w32.$(O)): Update dependencies.
1332 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1334 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1335 propagate redisplay's scrolling (if any) to the right window.
1336 (redisplay_internal): Use ensure_selected_frame.
1337 (display_mode_lines): Complete last fix.
1338 * window.c (select_window_1): New func, extracted from select_window.
1339 (select_window): Use it.

1366 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1368 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1369 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1370 for some of that bug's symptoms can now cause Emacs to abort.
1371 Remove the workaround.
1372 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1373 The bug that caused SIGCHLD to get lost has been fixed, and the
1374 workaround for it can now cause Emacs to abort.
1376 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1378 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1379 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1380 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1420 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1421 asynchronous subprocess, record the name of the input file name,
1423 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1424 delete the file, record it as pending deletion when the subprocess
1427 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1429 * editfns.c [HAVE_PWD_H]: Include grp.h.
1431 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1433 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1435 Fix permissions bugs with setgid directories etc. (Bug#13125)
1436 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1437 to mark it as a placeholder. The old value was often wrong.
1438 The only user of this attribute has been changed to use
1439 file-ownership-preserved-p instead, with its new group arg.
1440 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

1447 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1449 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1450 try to get accurate owner and group information from NT file
1451 security APIs. This is to make most callers of 'stat' and
1452 'lstat', which don't need that information, much faster.
1454 * dired.c (Ffile_attributes) [WINDOWSNT]:
1455 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1456 owner and group information from 'lstat'.
1458 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1460 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1461 as that confuses set-auto-coding, so insist on the head-read
1462 returning the full 1024 bytes. Let lseek compute the tail offset;
1463 less work for us. Do not ignore I/O errors when reading the tail.
1465 * xdisp.c: Minor style fixes.
1466 (init_iterator): Hoist assignment out of if-expression.
1467 (markpos_of_region): Callers now test for sign, not for -1.

1486 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1487 files, fixing a regression from 24.2.
1488 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1490 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1492 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1493 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1494 Remove unnecessary S_ISLNK test, as (contra the comments) this
1495 function can't copy symlinks. Improve quality of error message
1496 when attempting to copy files that are neither regular files nor

1510 the dumped Emacs is not a sparse file, greatly improving Cygwin
1511 "make bootstrap" performance.

1515 * inotify.c (inotify_callback): Generate an Emacs event for every
1516 incoming inotify event.
1518 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1520 * xdisp.c (handle_face_prop): Fix logic of computing
1521 it->start_of_box_run_p.
1522 (append_space_for_newline): If the glyph row is R2L, reset the
1523 iterator's end_of_box_run_p flag before prepending the space glyph.
1524 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1525 iterator's start_of_box_run_p flag before prepending the stretch.
1526 (append_glyph, produce_image_glyph, append_composite_glyph)
1527 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1528 left_box_line_p and right_box_line_p flags of the glyph for R2L
1529 glyph rows. (Bug#13011)
1531 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1536 * window.c (replace_buffer_in_windows_safely): Do nothing
1537 if buffer is not shown in a window.

1543 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1544 encoded_file_name, which is what it is.
1546 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1548 Consistently use marker_position and marker_byte_position.
1549 * fringe.c (Ffringe_bitmaps_at_pos):

1572 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1575 * w32fns.c (cache_system_info): Initialize the global hinst
1576 variable here so various initialization calls DTRT.
1578 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1579 (hinst): Remove unneeded extern declaration.
1580 (_start): Remove initialization of above variables; remove
1581 initialization of hinst, as cache_system_info now does that.
1583 * emacs.c (main): Call cache_system_info early in startup; we
1584 previously weren't calling it in Cygwin builds.
1586 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
1587 Teach the autoconf build system how to compile a Windows resource file
1588 and link it to Emacs.

1725 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1727 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

1729 * dbusbind.c (Fdbus_init_bus):
1731 * xterm.c (x_term_init):

1800 * frame.c (make_frame): Do not set window's buffer to t.
1801 * window.c (Fsplit_window_internal): Likewise. Previously it was
1802 used to indicate that the window is being set up. Now we use
1803 set_window_buffer for all new windows, so the condition in ...
1804 (Fset_window_buffer): ... is always true and can be removed.
1806 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1808 Convenient macro to check whether the buffer is hidden.
1809 * buffer.h (BUFFER_HIDDEN_P): New macro.

1822 * frame.h (x_char_width, x_char_height): Remove prototypes.

1836 * callproc.c, process.h (record_kill_process):
1837 New function, containing part of the old call_process_kill.
1838 (call_process_kill): Use it.
1839 This does not change call_process_kill's behavior.
1840 * process.c (Fdelete_process): Use record_kill_process to fix a
1841 race condition that could cause Emacs to lose track of a child.
1843 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1845 Avoid code duplication between prev_frame and next_frame.
1846 * frame.c (candidate_frame): New function. Add comment.

1849 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1851 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1852 fails, signal an error instead of continuing with an empty
1854 Encode expanded temp file pattern before passing it to mkstemp or
1857 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1858 Encode the file name before passing it to dostounix_filename, in
1859 case it will downcase it (under w32-downcase-file-names).
1862 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1864 Minor call-process cleanups.
1865 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1866 at the same time as other platforms, to simplify analysis.
1867 No need for fd0_volatile since we have synch_process_fd.
1868 Avoid needless emacs_close; arg is always negative.
1870 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1872 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

1884 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1885 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1886 members to a bitfields.
1888 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1890 Don't let call-process be a zombie factory (Bug#12980).
1891 Fixing this bug required some cleanup of the signal-handling code.
1892 As a side effect, this change also fixes a longstanding rare race
1893 condition whereby Emacs could mistakenly kill unrelated processes,
1894 and it fixes a bug where a second C-g does not kill a recalcitrant
1895 synchronous process in GNU/Linux and similar platforms.
1896 The patch should also fix the last vestiges of Bug#9488,
1897 a bug which has mostly been fixed on the trunk by other changes.
1898 * callproc.c, process.h (synch_process_alive, synch_process_death)
1899 (synch_process_termsig, sync_process_retcode):
1900 Remove. All uses removed, to simplify analysis and so that
1901 less consing is done inside critical sections.
1902 * callproc.c (call_process_exited): Remove. All uses replaced
1903 with !synch_process_pid.
1904 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1905 These take the role of what used to be in unwind-protect arg.
1907 (block_child_signal, unblock_child_signal):
1908 New functions, to avoid races that could kill innocent-victim processes.
1909 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1910 (call_process_kill): Record killed processes as deleted, so that
1911 zombies do not clutter up the system. Do this inside a critical
1912 section, to avoid a race that would allow the clutter.
1913 (call_process_cleanup): Fix code so that the second C-g works again
1914 on common platforms such as GNU/Linux.
1915 (Fcall_process): Create the child process in a critical section,
1916 to fix a race condition. If creating an asynchronous process,
1917 record it as deleted so that zombies do not clutter up the system.
1918 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1919 light of these changes. Omit unnecessary call to emacs_close
1920 before failure, as the unwind-protect code does that.
1921 * callproc.c (call_process_cleanup):
1922 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1923 * process.c (record_deleted_pid): New function, containing
1924 code refactored out of Fdelete_process.
1925 (Fdelete_process): Use it.
1926 (process_status_retrieved): Remove. All callers changed to use
1927 child_status_change.
1928 (record_child_status_change): Remove, folding its contents into ...
1929 (handle_child_signal): ... this signal handler. Now, this
1930 function is purely a handler for SIGCHLD, and is not called after
1931 a synchronous waitpid returns; the synchronous code is moved to
1932 wait_for_termination. There is no need to worry about reaping
1933 more than one child now.
1934 * sysdep.c (get_child_status, child_status_changed): New functions.
1935 (wait_for_termination): Now takes int * status and bool
1936 interruptible arguments, too. Do not record child status change;
1937 that's now the caller's responsibility. All callers changed.
1938 Reimplement in terms of get_child_status.
1939 (wait_for_termination_1, interruptible_wait_for_termination):
1940 Remove. All callers changed to use wait_for_termination.
1941 * syswait.h: Include <stdbool.h>, for bool.
1942 (record_child_status_change, interruptible_wait_for_termination):
1944 (record_deleted_pid, child_status_changed): New decls.
1945 (wait_for_termination): Adjust to API changes noted above.
1947 * bytecode.c, lisp.h (Qbytecode): Remove.
1948 No longer needed after 2012-11-20 interactive-p changes.
1950 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1952 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1953 the scroll margin, move point outside the margin. (Bug#13055)
1955 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1957 * gtkutil.c (my_log_handler): New function.
1958 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1960 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1962 * lisp.h (modify_region): Rename to...
1963 (modify_region_1): ...new prototype.
1964 * textprop.c (modify_region): Now static. Adjust users.
1965 * insdel.c (modify_region): Rename to...
1966 (modify_region_1): ...new function to work with current buffer.
1967 Adjust comment and users. Use true and false for booleans.
1969 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1971 * alloc.c (free_save_value): New function.
1972 (safe_alloca_unwind): Use it.
1973 * lisp.h (free_save_value): New prototype.
1974 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1976 (save_excursion_restore): Adjust to match saved data structure.
1977 Use free_save_value to offload some work from GC. Drop obsolete
1980 2012-12-03 Chong Yidong <cyd@gnu.org>
1982 * fileio.c (Vauto_save_list_file_name): Doc fix.
1984 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1986 * w32fns.c: Remove prototype of atof.
1987 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1989 (file_dialog_callback): Make it UINT_PTR.
1991 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1994 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1995 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1998 2012-12-03 Glenn Morris <rgm@gnu.org>
2000 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2002 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2004 Fix xpalloc confusion after memory is exhausted.
2005 * alloc.c (xpalloc): Comment fix.
2006 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2007 and signals an error, do not clear charset_table_size, as
2008 charset_table is still valid.
2009 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2011 Use execve to avoid need to munge environ (Bug#13054).
2012 * callproc.c (Fcall_process):
2013 * process.c (create_process):
2014 Don't save and restore environ; no longer needed.
2015 * callproc.c (child_setup):
2016 Use execve, not execvp, to preserve environ.
2018 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2020 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2022 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2024 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2025 display for sliced images (Bug#10500).
2027 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2029 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2031 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2032 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2034 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2036 * xdisp.c (window_outdated): Remove eassert since it hits
2037 some suspicious corner cases (see Bug#13007 and Bug#13012).
2038 (mode_line_update_needed): New function.
2039 (redisplay_internal, redisplay_window): Use it.

2041 (redisplay_internal, unwind_redisplay): Use it.
2042 (redisplay_internal): Move comment about buffer_shared...
2043 (buffer_shared_and_changed): ...near to its real use.
2045 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2047 * callproc.c (Fcall_process): Don't misreport vfork failure.
2049 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2051 * callproc.c (Fcall_process): Fix vfork portability problems.
2052 Do not assume that fd[0], count, filefd, and save_environ survive
2053 vfork. Fix bug whereby wrong errno value could be reported for
2054 pipe failure. Some minor cleanups, too, as follows. Move buf and
2055 bufsize to the context where they're needed. Change new_argv to
2056 be of type char **, as this is more convenient and avoids casts.
2057 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2058 Now local constants, not macros.
2060 2012-11-18 Kenichi Handa <handa@gnu.org>
2062 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2063 for the variable "f".

2067 * font.c (font_unparse_xlfd): Exclude special characters from the
2068 generating XLFD name.

2110 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2111 between bpos_covered and bpos_max. This fixes cursor display when
2112 several display strings follow each other.
2114 * .gdbinit (pgx): If the glyph's object is a string, display the
2115 pointer to string data, rather than the value of the string object
2116 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2118 * indent.c (Fvertical_motion): If the starting position is covered
2119 by a display string, return to one position before that, to avoid
2120 overshooting it inside move_it_to. (Bug#12930)
2122 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2124 * frame.h (struct frame): Remove display_preempted member

2133 Drop unused pending_menu_activation member.
2134 * xterm.h (struct x_output): Drop outdated #if 0 code.
2135 Use bitfields for explicit_parent, asked_for_visible,
2136 has_been_visible and net_wm_state_hidden_seen members.

2147 * dired.c: Assume HAVE_DIRENT_H.
2148 (NAMLEN): Remove, replacing with ...
2149 (dirent_namelen): New function. All uses changed. Use the GNU macro
2150 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2151 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2152 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2153 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2155 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2156 * ndir.h: Rename to ../nt/inc/dirent.h.
2157 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2158 Do not include <dirent.h>; no longer needed.
2159 * w32.c: Include <dirent.h> rather than "ndir.h".
2161 2012-11-23 Chong Yidong <cyd@gnu.org>
2163 * xftfont.c (xftfont_open): Remove duplicate assignment.
2165 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2167 * alloc.c (Fgarbage_collect): Unblock input after clearing
2168 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2169 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2170 * msdos.c (IT_frame_up_to_date): Use it here...
2171 * w32term.c (w32_frame_up_to_date): ...here...
2172 * xterm.c (XTframe_up_to_date): ...and here...
2173 * nsterm.m (ns_frame_up_to_date): ...but not here.
2174 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2176 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2177 Do not check whether GC is in progress.
2179 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2181 * xdisp.c (window_buffer_changed): New function.
2182 (update_menu_bar, update_tool_bar): Use it to
2183 simplify large 'if' statements.
2184 (redisplay_internal): Generalize commonly used
2185 'tail' and 'frame' local variables.
2187 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2189 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2190 with Windows system header.
2192 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2194 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2195 * alloc.c: Assume unistd.h exists.

2199 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2200 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2201 * w32.h (getcwd): Remove decl.
2203 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2205 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2206 Make it set selected_window as well.

2209 2012-11-21 Ken Brown <kbrown@cornell.edu>
2211 * emacs.c (main): Set the G_SLICE environment variable for all
2212 Cygwin builds, not just GTK builds. See
2213 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2215 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2217 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2218 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2219 Define for the MSVC compiler.
2221 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2223 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2224 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2225 dostounix_filename. Prevents crashes down the road, because
2226 dostounix_filename assumes it gets a unibyte string.
2227 Reported by Michel de Ruiter <michel@sentient.nl>, see
2228 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

2259 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2260 (syms_of_eval): Remove corresponding defsubr.
2261 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2263 2012-11-19 Daniel Colascione <dancol@dancol.org>
2265 * w32fns.c (Fx_file_dialog):
2266 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2267 cygwin_convert_file_name*.
2269 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2270 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2272 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2274 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2276 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2278 * w32select.c: Include w32common.h before w32term.h, so that
2279 windows.h gets included before w32term.h uses some of its
2280 features, see below.
2282 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2284 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2288 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2290 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2291 (ns_select): Return at once if events are held (Bug#12834).
2293 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2295 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2296 Needed following 2012-10-20 change. (Bug#12902)
2298 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2300 * w32proc.c (waitpid): Remove unused label get_result.
2302 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2304 * makefile.w32-in (SYSWAIT_H): New macro.
2305 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2306 ($(BLD)/sysdep.$(O)): Update dependencies.
2308 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2310 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2311 * callproc.c (relocate_fd): Assume F_DUPFD.
2312 * emacs.c, term.c (O_RDWR): Remove.
2313 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2314 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2315 * nsterm.m: Assume <fcntl.h> exists.
2316 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2317 (create_pty, Fmake_network_process, server_accept_connection)
2318 (wait_reading_process_output, init_process_emacs):
2320 (wait_reading_process_output): Put in a special case for WINDOWSNT
2321 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2322 It's not clear this is needed, but it's a more-conservative change.
2323 (create_process): Assume FD_CLOEXEC.
2324 (create_process, create_pty): Assume O_NOCTTY.
2325 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2326 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2327 Omit if not DOS_NT, since F_GETFL is not defined there.
2328 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2329 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2331 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2332 lack it, since gnulib guarantees this.
2333 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2335 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2337 * w32.c (faccessat): Pretend that directories have the execute bit
2338 set. Emacs expects that, e.g., in files.el:cd-absolute.
2340 * w32proc.c (create_child): Don't clip the PID of the child
2341 process to fit into an Emacs integer, as this is no longer a
2343 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2344 reaping only the process specified by PID argument, if that is
2345 positive. Use PID instead of dead_child to know which process to
2346 reap. Wait for the child to die only if WNOHANG is not in
2348 (sys_select): Don't set dead_child.
2350 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2351 as it is no longer needed.
2353 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2355 (record_child_status_change): Remove the setting of
2356 record_at_most_one_child for the !WNOHANG case.
2358 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2360 Fix problems in ns port found by static checking.
2361 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2362 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2363 not to process group.
2364 (ns_select): Use emacs_write, not write, as that's more robust
2365 in the presence of signals.
2366 (fd_handler:): Check for read errors.
2368 2012-11-16 Glenn Morris <rgm@gnu.org>
2370 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2372 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2374 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2376 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2378 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2379 use the same value of thread handle.
2380 (start_timer_thread): If the timer thread exited (due to error),
2381 clean up by closing the two handles it used. Duplicate the caller
2382 thread's handle here, so it gets duplicated only once, when
2383 launching the timer thread. Set priority of the timer thread, not
2385 (getitimer): Don't duplicate the caller thread's handle here.
2388 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2390 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2393 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2395 Remove no-longer-used pty_max_bytes variable.
2396 * process.c (pty_max_bytes): Remove; unused.
2397 (send_process): Do not set it.
2399 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2401 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2402 Update dependencies.
2404 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2406 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2407 This follows up on the 2012-09-29 patch that removed indirection
2408 for the 'function' field. Reported by Sergey Vinokurov in
2409 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2411 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2413 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2414 different name, as the MS runtime does not have such a function,
2415 and probably never will.) All callers changed. Ignore DIRFD
2416 value if PATH is an absolute file name, to match Posix spec
2417 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2420 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2422 * xdisp.c (echo_area_display, redisplay_internal):
2423 Omit redundant check whether frame_garbaged is set.
2425 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2427 Use faccessat, not access, when checking file permissions (Bug#12632).
2428 This fixes a bug that has been present in Emacs since its creation.
2429 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2430 which must set some sort of record. (Torek's bug report was against
2431 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2432 same common flaw.) See Torek's Usenet posting
2433 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2434 Posted: Fri Apr 8 14:18:56 1983.
2435 * Makefile.in (LIB_EACCESS): New macro.
2437 * callproc.c (init_callproc):
2438 * charset.c (init_charset):
2439 * fileio.c (check_existing, check_executable, check_writable)
2441 * lread.c (openp, load_path_check):
2442 * process.c (allocate_pty):
2444 Use effective UID when checking permissions, not real UID.
2445 * callproc.c (init_callproc):
2446 * charset.c (init_charset):
2447 * lread.c (load_path_check, init_lread):
2448 Test whether directories are accessible, not merely whether they exist.
2449 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2450 * fileio.c (check_existing, check_executable, check_writable)
2452 Use symbolic names instead of integers for the flags, as they're
2454 (check_writable): New arg AMODE. All uses changed.
2455 Set errno on failure.
2456 (Ffile_readable_p): Use faccessat, not stat + open + close.
2457 (Ffile_writable_p): No need to call check_existing + check_writable.
2458 Just call check_writable and then look at errno. This saves a syscall.
2459 dir should never be nil; replace an unnecessary runtime check
2460 with an eassert. When checking the parent directory of a nonexistent
2461 file, check that the directory is searchable as well as writable, as
2462 we can't create files in unsearchable directories.
2463 (file_directory_p): New function, which uses 'stat' on most platforms
2464 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2465 (Ffile_directory_p, Fset_file_times): Use it.
2466 (file_accessible_directory_p): New function, which uses a single
2467 syscall for efficiency.
2468 (Ffile_accessible_directory_p): Use it.
2469 * xrdb.c (file_p): Use file_directory_p.
2470 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2471 * lread.c (openp): When opening a file, use fstat rather than
2472 stat, as that avoids a permissions race. When not opening a file,
2473 use file_directory_p rather than stat.
2474 (dir_warning): First arg is now a usage string, not a format.
2475 Use errno. All uses changed.
2476 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2477 that merely introduced a race.
2478 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2479 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2480 and similarly for the other O_* flags.
2481 * w32.c (sys_faccessat): Rename from sys_access and switch to
2482 faccessat's API. All uses changed.
2483 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2484 (magic_db): Rename from magic_file_p.
2485 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2486 char *, so that we don't have to test for file existence
2487 separately from opening the file for reading. This removes a race
2488 fixes a permission-checking problem, and simplifies the code.
2490 (file_p): Remove; no longer needed.
2492 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2494 Omit glyphs initialization at startup.
2495 * dispnew.c (glyphs_initialized_initially_p): Remove.
2496 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2497 (Fredraw_frame): Move actual code from here...
2498 (redraw_frame): ...to here. Add eassert. Adjust comment.
2499 (Fredraw_display): Use redraw_frame.
2500 * xdisp.c (clear_garbaged_frames): Likewise.
2502 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2504 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2505 passed to pint2str and pint2hrstr to be at most the size of the
2506 frame's decode_mode_spec_buffer. This avoids crashes with very
2507 large values of FIELD_WIDTH argument to decode_mode_spec.
2510 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2512 Fix a race with verify-visited-file-modtime (Bug#12863).
2513 Since at least 1991 Emacs has ignored an mtime difference of no
2514 more than one second, but my guess is that this was to work around
2515 file system bugs that were fixed long ago. Since the race is
2516 causing problems now, let's remove that code.
2517 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2518 whose time stamp is off by no more than a second. Insist that the
2519 file time stamps match exactly.
2521 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2523 * frame.h (struct frame): Convert external_tool_bar member to
2524 1-bit unsigned bitfield.
2525 * termhooks.h (struct terminal): Remove mouse_moved member since
2526 all users are long dead. Adjust comment on mouse_position_hook.
2528 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2530 Simplify by using FOR_EACH_FRAME here and there.
2531 * frame.c (next_frame, prev_frame, other_visible_frames)
2532 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2533 * w32term.c (x_window_to_scroll_bar): Likewise.
2534 * window.c (window_list): Likewise.
2535 * xdisp.c (x_consider_frame_title): Likewise.
2536 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2537 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2538 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2539 * xmenu.c (menubar_id_to_frame): Likewise.
2540 * xselect.c (frame_for_x_selection): Likewise.
2541 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2542 (x_window_to_menu_bar): Likewise.
2543 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2545 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2547 * data.c (Qdefalias_fset_function): Now static.
2549 Another tweak to vectorlike_header change.
2550 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2551 Remove, and replace all uses with ...
2552 (next_in_free_list, set_next_in_free_list):
2553 New functions, which respect C's aliasing rules better.
2555 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2557 * window.c (list4i): Rename from 'quad'. All uses changed.
2558 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2560 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2562 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2563 warning about mixing declarations and code in ISO C90.
2565 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2567 * window.c (Fsplit_window_internal): Set combination limit of
2568 new parent window to t iff Vwindow_combination_limit is t;
2569 fixing a regression introduced with the change from 2012-09-22.
2570 (Fset_window_combination_limit): Fix doc-string.
2572 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2574 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2575 amount when the scroll margins are too large. When scrolling
2576 backwards in the buffer, give up if cannot reach point or the
2577 scroll margin within a reasonable number of screen lines.
2578 Fixes point position in window under scroll-up/down-aggressively when
2579 point is positioned many lines beyond the window top/bottom.
2582 * ralloc.c (relinquish): If real_morecore fails to return memory
2583 to the system, don't crash; instead, leave the last heap
2584 unchanged and return. (Bug#12774)
2586 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2588 * lisp.h (AUTOLOADP): New macro.
2589 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2590 * data.c (Ffset): Remove special ad-advice-info handling.
2591 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2593 (Finteractive_form): Simplify.
2594 (Fquo): Don't insist on having at least 2 arguments.
2595 (Qdefalias_fset_function): New var.
2597 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2599 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2601 * nsfont.m (Qcondensed, Qexpanded): New variables.
2602 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2603 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2605 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2607 Fix recently introduced crash on MS-Windows (Bug#12839).
2608 * w32term.h (struct scroll_bar): Use convenient header.
2609 (SCROLL_BAR_VEC_SIZE): Remove.
2610 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2612 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2614 Tweak last vectorlike_header change.
2615 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2616 vectorlike object on the free list. This is introduced to avoid
2617 some (but not all) pointer casting and aliasing problems, see
2618 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2619 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2621 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2623 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2625 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2626 been removed, so remove them here also.
2628 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2630 * doc.c (Fdocumentation): Handle new property
2631 dynamic-docstring-function to replace the old ad-advice-info.
2633 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2635 * fns.c (Qeql, hashtest_eq): Now static.
2637 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2639 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2640 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2641 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2642 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2644 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2646 Use same hash function for hashfn_profiler as for hash_string etc.
2647 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2648 * lisp.h (sxhash_combine): New inline function, with the contents
2649 of the old SXHASH_COMBINE.
2650 * profiler.c (hashfn_profiler): Use it, instead of having a
2651 special hash function containing a comparison that always yields 1.
2653 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2655 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2656 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2657 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2660 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2662 * image.c (xpm_make_color_table_h): Fix compiler error because
2663 make_hash_table changed.
2665 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2667 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2669 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2671 Use ad-hoc comparison function for the profiler's hash-tables.
2672 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2673 (make_log): Use them.
2674 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2675 call Fequal any more.
2676 (Ffunction_equal): New function.
2677 (cmpfn_profiler, hashfn_profiler): New functions.

2684 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2685 (hash_lookup, hash_remove_from_table): Move assertion checking of
2686 hashfn result here. Check hash-equality before calling cmpfn.
2687 (Fmake_hash_table): Adjust call to make_hash_table.
2688 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2689 (syms_of_fns): Initialize them.

2693 * print.c (print_object): Adjust to new hash-table struct.
2694 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2696 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2698 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2699 value of w32-scroll-lock-modifier is neither nil nor one of the
2700 known key modifiers. (Bug#12806)
2702 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2704 Shrink struct vectorlike_header to the only size field.
2705 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2707 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2708 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2709 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2710 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2711 information from the vector header. Adjust comment.
2712 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2713 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2715 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
2716 (struct vectorlike_header): Remove next member. Adjust comment.

2719 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
2720 (sweep_string, lisp_malloc): Remove useless prototypes.
2721 (enum mem_type): Adjust comment.
2722 (NEXT_IN_FREE_LIST): New macro.
2723 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2724 (Fmake_bool_vector): Likewise.
2725 (struct large_vector): New type to represent allocation unit for
2726 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2727 (large_vectors): Change type to struct large_vector.
2728 (allocate_vector_from_block): Simplify.
2729 (PSEUDOVECTOR_NBYTES): Replace with...
2730 (vector_nbytes): ...new function. Adjust users.
2731 (sweep_vectors): Adjust processing of large vectors.
2732 (allocate_vectorlike): Likewise.
2733 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2734 Add easserts. Adjust XSETPVECTYPESIZE usage.
2735 (allocate_buffer): Use BUFFER_PVEC_INIT.
2736 (live_vector_p): Adjust to match large vector.
2737 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2738 * buffer.h (struct buffer): Add next member.
2739 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2741 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2742 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2743 (copy_hash_table): Adjust to match vector header change.
2744 * lread.c (defsubr): Use XSETPVECTYPE.
2745 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2746 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2747 (xvecsize): New command.
2749 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2751 * keyboard.c (event_to_kboard): Do not dereference
2752 frame_or_window field of SELECTION_REQUEST_EVENT
2753 and SELECTION_CLEAR_EVENT events (Bug#12814).
2754 * xterm.h (struct selection_input_event): Adjust comment.
2756 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2758 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2759 such as Scroll Lock, if the respective keys are treated as
2760 function keys, not as modifiers. This avoids destroying non-ASCII
2761 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2763 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2765 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2767 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2769 Restore some duplicate definitions (Bug#12814).
2770 This undoes part of the 2012-11-03 changes. Some people build
2771 with plain -g rather than with -g3, and they need the duplicate
2772 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2773 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2774 Define as macros, as well as as enums or as constants.
2776 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2778 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2779 to keypad keys (Bug#12816).
2781 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2783 Minor adjustments of recently-changed frame functions.
2784 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2785 known to be a frame (we're in the FRAMEP branch).
2786 * lisp.h (Qframep): Remove decl. frame.h declares this.
2787 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2788 since they're meant for Lisp fixnum values.
2790 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2792 * window.c (Fwindow_combination_limit): Revert to the only
2793 required argument and adjust docstring as suggested in

2799 Widely used frame validity and checking functions.
2800 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2801 * frame.c (decode_live_frame, decode_any_frame): New functions.
2802 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2803 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2804 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2805 (Fframe_pointer_visible_p): Use decode_any_frame.
2806 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2807 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2808 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.

2811 (frame_buffer_list, frame_buffer_predicate): Remove.
2812 * lisp.h (frame_buffer_predicate): Remove prototype.
2813 * buffer.c (Fother_buffer): Use decode_any_frame.
2814 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2815 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2816 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2817 (Fclose_font, Ffont_info): Use decode_live_frame.
2818 * fontset.c (check_fontset_name): Likewise.
2819 * terminal.c (Fframe_terminal): Likewise.
2820 * w32fns.c (check_x_frame): Likewise.
2821 * window.c (Fminibuffer_window, Fwindow_at)
2822 (Fcurrent_window_configuration): Likewise.

2842 (Fwindow_combination_limit): Allow zero number of arguments.
2844 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2846 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2848 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2849 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2850 file descriptor 2 for standard error. (Bug#12805)
2852 2012-11-05 Chong Yidong <cyd@gnu.org>
2854 * process.c (wait_reading_process_output): Revert previous change.
2856 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2858 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2859 This removes code that has been obsolete since around 1990.
2860 * callproc.c (Fcall_process):
2862 * process.c (create_process):
2863 * term.c (dissociate_if_controlling_tty):
2864 Assume setsid exists.
2865 * callproc.c (child_setup): Assume setpgid exists and behaves as
2866 per POSIX.1-1988 or later.
2867 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2868 * emacs.c (shut_down_emacs):
2869 * sysdep.c (sys_suspend, init_foreground_group):
2870 Assume getpgrp behaves as per POSIX.1-1998 or later.
2871 * msdos.c (setpgrp): Remove.
2872 (tcgetpgrp, setpgid, setsid): New functions.
2873 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2874 * term.c (no_controlling_tty): Remove; unused.
2875 * w32proc.c (setpgrp): Remove.
2876 (setsid, tcgetpgrp): New functions.
2878 Simplify by assuming __fpending.
2879 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2880 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2881 Do not assume that __fpending's result fits in int.
2883 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2885 Remove EMACS_OUTQSIZE+sleep hack.
2886 * dispnew.c (update_frame_1): Remove hack for terminals slower
2887 than 2400 bps, which throttled Emacs by having it sleep.
2888 This code hasn't worked since at least 2007, when the multi-tty stuff
2889 was added, and anyway those old terminals are long dead.
2890 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2891 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2893 Fix data-loss with --version (Bug#9574).
2894 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2895 as we can't assume that emacs_strerror is initialized, and strerror
2896 is good enough here.
2897 (main): Invoke atexit earlier, to catch earlier instances of
2898 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2900 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2902 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2903 (keyDown): Remap keypad keys to X11 virtual key codes.
2905 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2907 Fix data-loss with --batch (Bug#9574).
2908 * emacs.c: Include <close-stream.h>.
2909 (close_output_streams): New function.
2910 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2911 and handles errors appropriately.
2912 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2915 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2916 The symptom is a diagnostic "GLib-WARNING **: In call to
2917 g_spawn_sync(), exit status of a child process was requested but
2918 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2919 waitpid(), so exit status can't be returned." The diagnostic
2920 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2921 The real bug is a race condition between Emacs and glib: Emacs
2922 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2923 so that glib can't find it. Work around the bug by invoking
2924 waitpid only on subprocesses that Emacs itself creates.
2925 * process.c (create_process, record_child_status_change):
2926 Don't use special value -1 in pid field, as the caller now must
2927 know the pid rather than having the callee infer it.
2928 The inference was sometimes incorrect anyway, due to another race.
2929 (create_process): Set new 'alive' member if child is created.
2930 (process_status_retrieved): New function.
2931 (record_child_status_change): Use it.
2932 Accept negative 1st argument, which means to wait for the
2933 processes that Emacs already knows about. Move special-case code
2934 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2935 processes that have already been waited for, by testing and
2936 clearing new 'alive' member.
2937 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2938 now does this internally.
2939 (handle_child_signal): Let record_child_status_change do all
2940 the work, since we do not want to reap all exited child processes,
2941 only the child processes that Emacs itself created.
2942 * process.h (Lisp_Process): New boolean member 'alive'.
2944 Omit duplicate definitions no longer needed with gcc -g3.
2945 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2946 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2947 Define only as macros. There's no longer any need to also define
2948 these symbols as enums or as constants, since we now assume
2949 gcc -g3 when debugging.
2951 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2953 * lisp.mk: Adjust comments to the fact that term/internal is now
2954 loaded from loadup.el.
2956 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2957 (msdos_fatal_signal): New function.
2958 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2961 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2962 for GCC versions before 4.
2963 (emacs_raise): Define to call msdos_fatal_signal.
2965 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2966 iterator when starting in the middle of a display or overlay
2969 2012-11-03 Chong Yidong <cyd@gnu.org>
2971 * process.c (wait_reading_process_output): Clean up the last
2974 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2976 * process.c (wait_reading_process_output): Avoid a race condition
2977 with SIGIO delivery (Bug#11536).
2979 2012-11-03 Chong Yidong <cyd@gnu.org>
2981 * buffer.c (cursor_type): Untabify docstring.
2983 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2985 * frame.h (struct frame): Drop can_have_scroll_bars member
2986 which is meaningless for a long time. Adjust comments.
2987 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2988 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2990 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2992 * window.c (decode_next_window_args): Update window arg after
2993 calling decode_live_window and so fix crash reported at
2994 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2995 by Juanma Barranquero <lekktu@gmail.com>.
2996 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2997 * font.c (Ffont_at): Likewise.
2999 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3001 * widget.c (resize_cb): New function.
3002 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3003 (EmacsFrameResize): Check if all is up to date before changing frame
3006 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3008 Implement backtrace output for fatal errors on MS-Windows.
3009 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3010 (BACKTRACE_LIMIT_MAX): New macro.
3011 (w32_backtrace): New function.
3012 (emacs_abort): Use w32_backtrace when the user chooses not to
3013 attach a debugger. Update the text of the abort dialog.
3015 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3017 Window-related stuff cleanup here and there.
3018 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3019 Use decode_any_window.
3020 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3021 * xdisp.c (Fformat_mode_line): Likewise.
3022 * font.c (Ffont_at): Use decode_live_window.
3023 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3024 * window.c (decode_next_window_args): Likewise.
3025 (decode_any_window): Remove static.
3026 * window.h (decode_any_window): Add prototype.
3027 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3028 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3031 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3033 Remove pad from struct input_event.
3034 * termhooks.h (struct input_event): Remove padding field.
3036 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3037 member is never cons for a long time. Adjust comment.
3038 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3039 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3040 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3041 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3043 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3045 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3047 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3049 Fix crash when using Emacs as commit editor for git (Bug#12697).
3050 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3051 and it is configured in conf_post.h.
3052 (Fcall_process): Don't invoke both setsid and setpgid; the former
3053 is enough, if it exists.
3054 * callproc.c (Fcall_process, child_setup):
3055 * process.c (create_process): Use setpgid.
3056 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3058 * dispnew.c (init_display): Initialize the foreground group
3059 if we are running a tty display.
3060 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3061 * lisp.h (init_foreground_group): New decl.
3062 * sysdep.c (inherited_pgroup): New static var.
3063 (init_foreground_group, tcsetpgrp_without_stopping)
3064 (narrow_foreground_group, widen_foreground_group): New functions.
3065 (init_sys_modes): Narrow foreground group.
3066 (reset_sys_modes): Widen foreground group.
3068 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3070 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3072 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3074 * minibuf.c (read_minibuf): Restore current buffer since
3075 choose_minibuf_frame calling Fset_frame_selected_window may
3076 change it (Bug#12766).
3078 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3080 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3082 2012-10-30 Kenichi Handa <handa@gnu.org>
3084 * font.c (Ffont_at): If WINDOW is specified and it is not
3085 displaying the current buffer, signal an error.
3087 2012-10-29 Daniel Colascione <dancol@dancol.org>
3089 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3090 In preparation for fixing bug#12739, move these functions from
3093 * coding.h, coding.c: ... to here, and compile them only when
3094 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3095 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3097 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3099 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3100 (timer_loop, getitimer, setitimer): Use it instead of
3101 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3103 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3106 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3108 * nsterm.m (NO_APPDEFINED_DATA): New define.
3109 (last_appdefined_event_data): New variable
3110 (last_appdefined_event): Remove.
3111 (ns_select): Initialize t from last_appdefined_event_data instead
3112 of [last_appdefined_event data1].
3113 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3114 remove last_appdefined_event (Bug#12698).
3116 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3118 * frame.c (x_set_font): Catch internal error.
3120 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3122 Avoid overflow in w32 implementation of interval timers.
3123 When possible, for ITIMER_PROF count only times the main thread
3125 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3126 'volatile ULONGLONG' types. All the other data which was
3127 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3128 (GetThreadTimes_Proc): New typedef.
3129 (w32_get_timer_time): New function, returns a suitable time value
3131 (timer_loop): Enter critical section when accessing ULONGLONG
3132 values of the itimer_data struct, as these accesses are no longer
3133 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3134 Remove unused variable.
3135 (init_timers): Initialize s_pfn_Get_Thread_Times.
3136 (start_timer_thread): Don't assign itimer->caller_thread here.
3137 (getitimer): Assign itimer->caller_thread here.
3138 (setitimer): Always call getitimer to get the value of ticks_now.
3139 (sys_spawnve): Avoid compiler warning about format mismatch.
3141 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3143 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3144 mouse movement events if the menu bar is active. This avoids
3145 producing a busy "hour-glass" cursor by Windows if the mouse
3146 pointer is positioned over a tooltip shown for some menu item.
3148 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3150 Don't assume process IDs fit in int.
3151 * emacs.c (shut_down_emacs) [!DOS_NT]:
3152 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3153 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3154 Use pid_t, not int, to store process IDs, as 'int'
3155 is not wide enough on a few platforms (e.g., AIX and IRIX).
3157 2012-10-23 Kenichi Handa <handa@gnu.org>
3159 The following change is to make face-font-rescale-alist work
3160 correctly for non-ASCII fonts.
3162 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3163 (font_open_for_lface): Handle Vface_font_rescale_alist.
3165 2012-10-23 Chong Yidong <cyd@gnu.org>
3167 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3169 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3171 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3173 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3175 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3178 2012-10-21 Glenn Morris <rgm@gnu.org>
3180 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3182 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3184 Port to OpenBSD 5.1.
3185 * frame.c (Fmouse_position, Fmouse_pixel_position):
3186 * xdisp.c (produce_stretch_glyph):
3187 Declare local vars only when they're needed.
3188 This is clearer and avoids a warning on OpenBSD about unused vars.
3189 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3190 This is safer, and avoids OpenBSD warnings about unused vars.
3191 * keyboard.c (record_menu_key): Remove unnecessary decl.
3192 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3193 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3194 as our definition clashes with OpenBSD's.
3195 * xfaces.c (load_face_colors, check_lface_attrs)
3196 (get_lface_attributes_no_remap, get_lface_attributes)
3197 (lface_fully_specified_p, x_supports_face_attributes_p)
3198 (tty_supports_face_attributes_p, face_fontset, realize_face)
3199 (realize_x_face, realize_tty_face):
3200 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3201 merely Lisp_Object *. This is more informative and avoids
3202 a warning on OpenBSD about accessing beyond an object's size.
3204 2012-10-20 Chong Yidong <cyd@gnu.org>
3206 * lread.c (Fload): Doc fix (Bug#12592).
3208 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3210 * font.c (Ffont_at): Fix previous change.
3212 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3214 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3215 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3218 * alloc.c (NSTATICS): Decrease to 0x800.
3220 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
3222 * fns.c (Fnreverse): Include the problem element when signaling an
3225 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
3227 * nsterm.m (ns_select): Check writefds before call to
3228 FD_ISSET (Bug#12668).
3230 2012-10-18 Daniel Colascione <dancol@dancol.org>
3232 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3233 (staticpro): If we run out of staticpro slots, die with an
3234 informative error instead of just calling emacs_abort.
3236 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3238 Fix two flaws reported by Dmitry Antipov.
3239 * window.c (Ftemp_output_buffer_show): Remove.
3240 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
3241 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
3243 2012-10-17 Eli Zaretskii <eliz@gnu.org>
3245 * makefile.w32-in ($(BLD)/w32.$(O)):

3493 since unsigned is guaranteed to have that behavior and signed is not.
3494 (read_char): Use ptrdiff_t for string length.
3495 (get_input_pending): Remove first argument, since it was always
3496 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3497 and behave as if it had that value. Return new value of
3498 input_pending. All callers changed.
3499 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3500 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3529 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3531 * commands.h (immediate_quit): Remove duplicate decl.

3543 match what GetLastError returns. Explain why the function is
3546 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3547 'is_tooltip_frame', to avoid confusion with its global namesake.
3549 2012-10-08 Daniel Colascione <dancol@dancol.org>
3551 * xdisp.c (start_hourglass): Call w32_note_current_window when
3552 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3553 build that caused Emacs to display the hourglass cursor forever.
3555 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3556 which is broken under remote desktop, calculate the number of
3557 colors available for a display based on the display's number of
3558 planes and number of bits per pixel per plane. (bug#10397).
3560 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3562 * nsfont.m (Vfonts_in_cache): New variable.
3563 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3564 are used. Add cached fonts to Vfonts_in_cache.
3565 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3567 2012-10-08 Juanma Barranquero <lekktu@gmail.com>

3591 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now

3595 2012-10-08 Daniel Colascione <dancol@dancol.org>
3597 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3598 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3599 accidental message numbering hole. Change other messages to

3619 * w32fns.c: Include w32common.h; include w32heap.h only in
3622 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3623 Use `report_file_error' instead of `error' in order to better
3624 inform users of what went wrong. Increase NTGUI_UNICODE file
3625 dialog box file name length to 32k, the maximum allowed by the NT
3628 * w32common.h: New file.
3629 (ROUND_UP, ROUND_DOWN, get_page_size)

3633 (OS_NT, os_subtype, cache_system_info): Move here.
3635 * unexw32.c, unexcw.c: Include w32common.h.
3637 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3638 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3639 to call syms_of_w32select.
3641 * cygw32.h: Remove obsolete EXFUN declarations.
3643 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3655 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3657 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3660 2012-10-08 Daniel Colascione <dancol@dancol.org>
3662 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3663 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3664 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

3667 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3668 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3669 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3670 now a supported configuration.
3672 * Makefile.in: consolidate image variables into LIBIMAGE; add
3673 W32_OBJ and W32_LIBS. Compile new files.
3676 (_DebPrint) declare tracing facility for W32 debugging. We need
3677 to unify tracing later.
3679 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3680 unconditional use of W32 Unicode functions. Cygwin runs only on
3681 100% Unicode operating systems.
3683 * cygw32.c: New file. Define Cygwin-specific facilities.
3684 (Fcygwin_convert_path_to_windows)
3685 (Fcygwin_convert_path_from_windows): New user functions for
3686 accessing Cygwin path-munging routines.
3688 * cygw32.h: New file.
3689 (WCSDATA, to_unicode, from_unicode): Define facilities for storing

3693 (w32_strerror): Just what it says on the tin.
3695 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3696 also run for Cygwin; both systems have the same problem with using
3697 GUI facilities in a forked child. Also call syms_of_cygw32,
3698 syms_of_w32select in correct places.
3700 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3701 needs fork-then-exec for daemon launching.
3703 * font.h: Include frame.h.
3705 * image.c: Use the image library cache machinery only when we're
3706 compiling for native WINDOWSNT; Cygwin can use shared libraries
3707 like any other Unixlike system.
3709 * keyboard.c: Clarify a comment regarding the input loop.
3711 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3712 functions directly instead of trying to detect at runtime that our
3713 host operating system supports them. We make this change for two
3714 reasons: Cygwin lacks support for the multibyte character
3715 conversion functions used by the legacy menu code, and Cygwin
3716 never needs to rely on non-Unicode APIs.
3718 * unexw32.c (hinst): Declare extern.
3720 * w32.c: Change header order;
3721 (w32_strerror): Move to w32fns.c because we need it for
3722 non-WINDOWSNT builds.
3724 * w32.h: Add #error macro to make sure we don't include w32.h for
3725 Cygwin builds. Remove w32select declarations.
3727 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3728 w32fns.c. w32console.c is WINDOWSNT-only.
3730 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3731 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3733 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3734 (w32_major_version, w32_minor_version, w32_build_number)
3735 (os_subtype, sound_type): Define here
3736 (w32_defined_color): Make color parameter const for consistency
3737 with other _defined_color functions.
3738 (w32_createwindow): Unconditionally call w32_init_class instead of
3739 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3740 through the code is complex and unnecessary because class
3741 registration is practically free.
3742 (w32_name_of_message): New EMACSDEBUG-only function.
3743 (Fset_message_beep): Move here
3744 (Fx_open_connection): Require that the display name for Windows be
3745 "w32" for consistency, emacsclient disambiguation, and maybe, one
3746 day, multi-window-system support.
3747 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3748 Cygwin files for W32 GUI facilities, since these clearly don't
3749 expect Cygwin names.
3750 (_DebPrint): Define.
3751 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3752 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3753 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3754 (w32_last_error): Remove.
3756 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3758 * w32heap.c (syspage_mask): Declare here.
3759 (cache_system_info): Remove.
3761 * w32inevt.c (faked_key): Define globally, not statically.
3762 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3763 (w32_console_toggle_lock_key): Move to w32fns.c.
3765 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3767 * w32proc.c (_DebPrint): Move to w32fns.c.
3768 * w32select.c: Include string.h, stdio.h for Cygwin.
3769 * w32select.h: New File.
3771 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3773 (w32_message_fd): New variable. Under Cygwin, holds the file
3774 descriptor the system used to tell us about pending thread
3777 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3778 that prevented compilation under non-WINDOWSNT systems.
3780 (w32_initialize): Open /dev/windows and assign it to
3781 w32_message_fd. Provide w32 feature.
3783 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3784 (WM_EMACS_INPUT_READY): add.
3785 (prepend_msg, w32_message_fd): Declare globally.
3788 (keyboard_handle): Use only when WINDOWSNT.
3789 (notify_msg_ready): New function. Posts a message to the main
3790 thread's message queue under CYGWIN, which wakes up the main
3791 thread from select(2) by making the /dev/windows file descriptor
3792 ready. Under WINDOWSNT, it sets an event the same way the old
3795 (post, prepend_msg): Actually call notify_msg_ready instead of
3796 setting the input event directly.
3798 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3800 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3801 but it still has blocs in it, don't return it to the system,
3802 instead of aborting. (Bug#12402)
3804 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3806 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3808 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3809 MAC_OS_X_VERSION_10_6.
3810 (syms_of_nsterm): Remove comment about Panther and above for
3812 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

3814 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3816 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3817 MAC_OS_X_VERSION_10_4.
3819 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3820 MAC_OS_X_VERSION_10_2.
3822 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3824 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3825 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3827 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3828 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3829 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3830 Remove ns_in_resize check.

3834 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3835 Remove ns_in_resize check.
3837 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3839 Improve sys_siglist detection.
3840 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3841 defined as a macro, as is done in Solaris.
3842 (sys_siglist_entries): New macro.
3843 (save_strsignal): Use it.
3844 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3845 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3847 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3849 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3850 fullscreen/Fullscreen.
3852 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3853 tobar_height is new.
3855 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3856 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3857 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3858 (windowDidResize:): Check for correct window if old style fullscreen.
3859 Capitalize word in comment. Remove incorrect comment.
3860 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3861 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3862 error in drawing background.
3863 (toggleFullScreen:): Remove comment. Rearrange calls.
3864 Set toolbar values to zero, save old height in tobar_height.
3865 Restore tool bar height when leaving fullscreen.
3866 (canBecomeMainWindow): New function.
3868 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3870 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3872 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3874 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3876 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3877 that time stamps of directories could also be changed.
3878 Don't request the too broad GENERIC_WRITE, only the more restrictive
3879 FILE_WRITE_ATTRIBUTES access rights.
3881 * fileio.c (Fset_file_times): Special-case ignoring errors for
3882 directories only on MSDOS, not on MS-Windows.
3884 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3886 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3888 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3890 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3891 see whether CreateFile failed.
3893 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3895 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3896 to avoid similar races.
3897 * keyboard.c (pending_signals): Now bool, not int.
3899 Port timers to OpenBSD, plus check for timer failures.
3900 OpenBSD problem reported by Han Boetes.
3901 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3903 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3904 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3905 like OpenBSD, which has timer_settime but does not declare it.
3906 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3907 whether to use itimerspec-related primitives. All uses of
3908 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3910 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3912 * profiler.c (handle_profiler_signal): Fix a malloc race
3913 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3915 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3917 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3919 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3921 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3922 consistent with the change in return value of 'safe_strsignal'.
3924 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3926 Prefer plain 'static' to 'static inline' (Bug#12541).
3927 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3928 (bidi_set_sor_type, bidi_push_embedding_level)
3929 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3930 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3934 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3935 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3936 Now 'static', not 'static inline'.
3938 Count overruns when profiling; change units to ns.
3939 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3940 Give extra weight to samples after overruns, to attempt to count
3941 the time more accurately.
3942 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3943 the underlying primitives nominally do ns.
3944 (Fprofiler_cpu_start): Document the change. Mention that
3945 the sampling intervals are only approximate.
3947 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3949 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3951 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3952 case for the special 0 coding-system.
3954 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3955 (Fmake_overlay): Remove redundant tests.
3956 (fix_start_end_in_overlays): Remove redundant recentering.
3958 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3960 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3961 Update dependencies.
3963 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3965 Fix a malloc race condition involving strsignal.
3966 A signal can arrive in the middle of a malloc, and Emacs's signal
3967 handler can invoke strsignal, which can invoke malloc, which is
3968 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3969 Fix it by altering the signal handler so that it does not invoke
3971 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3972 * process.c (status_message): Use const pointer, in case strsignal
3973 is #defined to safe_strsignal.
3974 * sysdep.c (sys_siglist, init_signals): Always define and
3975 initialize a substitute sys_siglist if the system does not define
3976 one, even if HAVE_STRSIGNAL.
3977 (safe_strsignal): Rename from strsignal. Always define,
3978 using sys_siglist. Return a const pointer.
3979 * syssignal.h (safe_strsignal): New decl.
3980 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3982 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3984 * w32proc.c (timer_loop): Fix code that waits for timer
3985 expiration, to avoid high CPU usage.
3987 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3989 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3990 (sweep_weak_table): Remove redundant prototypes.
3992 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3994 * emacs.c: Move the inclusion of TERM_HEADER after including
3995 windows.h on WINDOWSNT. This avoids compilation problems with
3998 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4000 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4001 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4002 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4003 as the previous version used 'void *'.
4005 * ralloc.c (ROUNDUP): Fix last change.
4006 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4009 * w32proc.c <disable_itimers>: New static flag.
4010 (init_timers): Initialize it to zero, after creating the critical
4011 sections used by the timer threads.
4012 (term_timers): Set to 1 before deleting the critical sections.
4013 (getitimer, setitimer): If disable_itimers is non-zero, return an
4014 error indication without doing anything. Reported by Fabrice
4015 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4016 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4018 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4021 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4022 term_ntproc after all the other bookkeeping, to get timers working
4023 as long as possible.
4025 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4027 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4028 Suggested by Juri Linkov in
4029 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4031 Prefer plain 'static' to 'static inline' (Bug#12541).
4032 With static functions, modern compilers inline pretty well by
4033 themselves; advice from programmers often hurts as much as it helps.
4034 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4035 this change shrinks the text size of the Emacs executable by 1.1%
4036 without affecting CPU significantly in my benchmark.
4037 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4038 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

4113 Now 'static', not 'static inline'.
4116 (bidi_copy_it): Do the whole copy with a single memcpy.
4117 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4119 Revert the FOLLOW-SYMLINKS change for file-attributes.
4120 Doing it right would require several changes to Tramp, and there's
4121 not enough time to get that tested before the freeze today.
4122 * dired.c (directory_files_internal, Ffile_attributes):
4125 * frame.c (x_report_frame_params): Port better to wider ints.
4126 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4127 or that pointers can be printed in 15 decimal digits.
4128 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

4309 Suggested by Eli Zaretskii in
4310 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
4312 2012-09-30 Eli Zaretskii <eliz@gnu.org>
4314 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
4315 HAVE_TIMER_SETTIME is defined.

4319 Profiler improvements: more-accurate timers, overflow checks.
4320 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4321 signal.h, setjmp.h. Include systime.h instead.

4329 All uses changed to store the new value.
4330 (handle_profiler_signal): Rename from sigprof_handler_1,
4331 for consistency with other handlers. Do not check whether
4332 cpu_log is a hash-table if garbage collecting, since it
4333 doesn't matter in that case.

4335 for consistency with other handlers.
4336 (setup_cpu_timer): New function, with much of what used to be in
4337 Fprofiler_cpu_start. Check for out-of-range argument.
4338 Prefer timer_settime if available, and prefer
4339 thread cputime clocks, then process cputime clocks, then
4340 monotonic clocks, to the old realtime clock. Use make_timeval
4341 to round more-correctly when falling back to setitimer.
4342 (Fprofiler_cpu_start): Use it.
4343 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4344 Don't assume that passing NULL as the 2nd argument of setitimer

4409 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4410 Since this stuff is now private to charset.c, there's no need for
4411 a public macro and no need to inline by hand.

4485 (sys_kill): Improve commentary.
4487 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4488 consistency with a signature of a signal handler. All callers
4490 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4491 install term_ntproc as a signal handler for SIGABRT, as that
4492 should be done by the dumped Emacs.

4613 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4615 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4616 fatal_error_backtrace.
4618 * w32proc.c (sys_kill): Undo last change: don't do anything when
4619 invoked to deliver SIGABRT to our own process. This is now
4620 handled by emacs_raise.
4622 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4624 * w32term.c (w32_read_socket): Remove leftover reference to
4625 interrupt_input_pending.
4627 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4629 Do not use SA_NODEFER.
4630 Problem reported by Dani Moncayo in
4631 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4633 * sysdep.c (emacs_abort): Do not reset signal handler.
4634 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4635 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4636 wanted even on POSIXish hosts, and it doesn't work on Windows.
4638 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4640 * xterm.c (x_term_init): Call fixup_locale before and after calling
4641 gtk_init (Bug#12392).
4643 2012-09-23 Chong Yidong <cyd@gnu.org>
4645 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4646 Vdynamic_library_alist.
4648 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4649 (Fgnutls_available_p): Caller changed.
4651 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4652 (Flibxml_parse_xml_region): Likewise.
4654 * dispextern.h (struct image_type): Remove arg from init function.
4656 * image.c (Finit_image_library, lookup_image_type)
4657 (define_image_type): Remove now-unneeded second arg.
4658 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4659 (init_tiff_functions, init_gif_functions, init_svg_functions):
4660 Arglist and w32_delayed_load calling convention changed.
4661 (gs_type): Remove init_gs_functions; there is no such function.
4662 (valid_image_p, make_image): Fix caller to lookup_image_type.
4664 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4666 Simplify and avoid signal-handling races (Bug#12471).
4668 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4669 Avoid recursive loop if there's a fatal error in the function itself.
4670 * atimer.c (pending_atimers):
4671 * blockinput.h: Don't include "atimer.h"; no longer needed.
4672 (interrupt_input_pending): Remove. All uses removed.
4673 pending_signals now counts both atimers and ordinary interrupts.
4674 This is less racy than having three separate pending-signal flags.
4675 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4677 Rename from their upper-case counterparts BLOCK_INPUT,
4678 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4679 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4680 This makes it easier to access volatile variables more accurately.
4681 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4682 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4683 that's more reliable if the code is buggy and sets
4684 interrupt_input_blocked to a negative value. All uses changed.
4685 * atimer.c (deliver_alarm_signal):
4686 Remove. No need to deliver this to the parent; any thread can
4687 handle this signal now. All uses replaced by underlying handler.
4688 * atimer.c (turn_on_atimers):
4689 * dispnew.c (handle_window_change_signal):
4690 * emacs.c (handle_danger_signal):
4691 * keyboard.c (kbd_buffer_get_event):
4692 Don't reestablish signal handler; not needed with sigaction.
4693 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4695 Rework to avoid unnecessary accesses to volatile variables.
4696 (UNBLOCK_INPUT_TO): Now a function.
4697 (totally_unblock_input, unblock_input): New decls.
4698 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4699 (init_data): Remove. Necessary stuff now done in init_signal.
4700 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4701 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4702 (fatal_error_code): Remove; no longer needed.
4703 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4704 it doesn't always backtrace. All uses changed. No need to reset
4705 signal to default, since sigaction and/or die does that for us now.
4706 Use emacs_raise (FOO), not kill (getpid (), FOO).
4707 (main): Check more-accurately whether we're dumping.
4708 Move fatal-error setup to sysdep.c
4709 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4710 * gtkutil.c (xg_get_file_name, xg_get_font):
4711 Remove no-longer-needed signal-mask manipulation.
4712 * keyboard.c, process.c (POLL_FOR_INPUT):
4713 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4714 * keyboard.c (read_avail_input): Remove.
4715 All uses replaced by gobble_input.
4716 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4717 (kbd_buffer_store_event_hold, gobble_input):
4718 (record_asynch_buffer_change) [USABLE_SIGIO]:
4719 (store_user_signal_events):
4720 No need to mess with signal mask.
4721 (gobble_input): If blocking input and there are terminals, simply
4722 set pending_signals to 1 and return. All hooks changed to not
4723 worry about whether input is blocked.
4724 (process_pending_signals): Clear pending_signals before processing
4725 them, in case a signal comes in while we're processing.
4726 By convention callers now test pending_signals before calling us.
4727 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4728 New functions, to support changes to blockinput.h.
4729 (handle_input_available_signal): Now extern.
4730 (reinvoke_input_signal): Remove. All uses replaced by
4732 (quit_count): Now volatile, since a signal handler uses it.
4733 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4734 All callers changed. Block SIGINT only if not already blocked.
4735 Clear sigmask reliably, even if Fsignal returns, which it can.
4736 Omit unnecessary accesses to volatile var.
4737 (quit_throw_to_read_char): No need to restore sigmask.
4738 * keyboard.c (gobble_input, handle_user_signal):
4739 * process.c (wait_reading_process_output):
4740 Call signal-handling code rather than killing ourselves.
4741 * lisp.h: Include <float.h>, for...
4742 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4743 (pending_signals): Now volatile.
4744 (syms_of_data): Now const if IEEE floating point.
4745 (handle_input_available_signal) [USABLE_SIGIO]:
4746 (terminate_due_to_signal, record_child_status_change): New decls.
4747 * process.c (create_process): Avoid disaster if memory is exhausted
4748 while we're processing a vfork, by tightening the critical section
4750 (send_process_frame, process_sent_to, handle_pipe_signal)
4751 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4753 (send_process): No need for setjmp/longjmp any more, since the
4754 SIGPIPE stuff is now gone. Instead, report an error if errno
4756 (record_child_status_change): Now extern. PID and W are now args.
4757 Return void, not bool. All callers changed.
4758 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4759 Remove. All uses removed. This bug should be fixed now in a
4761 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4762 and record the child status change directly. This avoids the
4763 need to futz with the signal mask.
4764 (process_fatal_action): Move here from emacs.c.
4765 (emacs_sigaction_flags): New function, containing
4766 much of what used to be in emacs_sigaction_init.
4767 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4768 caught by emacs, to make races less likely.
4769 (deliver_process_signal): Rename from handle_on_main_thread.
4771 (BACKTRACE_LIMIT_MAX): Now at top level.
4772 (thread_backtrace_buffer, threadback_backtrace_pointers):
4774 (deliver_thread_signal, deliver_fatal_thread_signal):
4775 New functions, for more-accurate delivery of thread-specific signals.
4776 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4777 (deliver_arith_signal): Handle in this thread, not
4778 in the main thread, since it's triggered by this thread.
4779 (maybe_fatal_sig): New function.
4780 (init_signals): New arg DUMPING so that we can be more accurate
4781 about whether we're dumping. Caller changed.
4782 Treat thread-specific signals differently from process-general signals.
4783 Block all signals while handling fatal error; that's safer.
4784 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4786 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4787 Ignore SIGPIPE unless batch.
4788 (emacs_backtrace): Output backtrace for the appropriate thread,
4789 which is not necessarily the main thread.
4790 * syssignal.h: Include <stdbool.h>.
4791 (emacs_raise): New macro.
4792 * xterm.c (x_connection_signal): Remove; no longer needed
4793 now that we use sigaction.
4794 (x_connection_closed): No need to mess with sigmask now.
4795 (x_initialize): No need to reset SIGPIPE handler here, since
4796 init_signals does this for us now.
4798 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4800 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4801 background rect may be larger (Bug#12245).
4803 2012-09-23 Chong Yidong <cyd@gnu.org>
4805 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4807 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4809 * .gdbinit: Just stop at fatal_error_backtrace.
4810 See Stefan Monnier's request in
4811 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4812 Remove no-longer-used query of system type.
4814 2012-09-22 Chong Yidong <cyd@gnu.org>
4816 * search.c (Freplace_match): Doc fix (Bug#12325).
4818 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4820 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4821 (Fline_end_position): Doc fix.
4823 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4825 2012-09-22 Chong Yidong <cyd@gnu.org>
4827 * dispextern.h (struct image_type): Add new slot, storing a type
4828 initialization function.
4830 * image.c (define_image_type): Call the image initializer function
4831 if it is defined. Arguments and return value changed.
4832 (valid_image_p, make_image): Callers changed.
4833 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4834 (gif_type, imagemagick_type, svg_type, gs_type):
4835 Add initialization functions.
4836 (Finit_image_library): Call lookup_image_type.
4837 (CHECK_LIB_AVAILABLE): Macro deleted.
4838 (lookup_image_type): Call define_image_type here, rather than via
4839 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4840 (syms_of_image): Move define_image_type calls for xbm_type and
4841 pbm_type to lookup_image_type.
4843 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4845 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4846 'idle_timers' from here ...
4847 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4848 lists, to avoid infloops when the timer does something stupid,
4849 like reinvoke itself with the same or smaller time-out.
4852 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4854 * window.c (Fsplit_window_internal): Handle only Qt value of
4855 Vwindow_combination_limit separately.
4856 (Qtemp_buffer_resize): New symbol.
4857 (Vwindow_combination_limit): New default value.
4860 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4862 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4863 the new overlay string. (Bug#10159)
4865 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4867 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4868 or that fprintf is async-signal-safe. POSIX doesn't require
4871 2012-09-22 Chong Yidong <cyd@gnu.org>
4873 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4876 2012-09-22 Kenichi Handa <handa@gnu.org>
4878 * composite.c (composition_reseat_it): Handle the case that a
4879 grapheme cluster is not covered by a single font (Bug#12352).
4881 2012-09-21 Chong Yidong <cyd@gnu.org>
4883 * image.c (define_image_type): Avoid adding duplicate types to
4884 image_types (Bug#12463). Suggested by Jörg Walter.
4886 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4888 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4889 (print_load_command_name): Add case LC_DATA_IN_CODE.
4890 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4892 2012-09-21 Glenn Morris <rgm@gnu.org>
4894 * eval.c (Frun_hook_with_args_until_success)
4895 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4897 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4899 * fileio.c (Ffile_selinux_context): Only call freecon when
4900 lgetfilecon succeeded.
4901 (Fset_file_selinux_context): Likewise. (Bug#12444)
4903 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4905 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4906 reordering, locate the cursor by calling set_cursor_from_row; if
4907 that fails, clear the desired glyph matrix before returning a
4908 failure indication to the caller. Fixes leaving garbled display
4909 when fast scrolling with a down-key. (Bug#12403)
4910 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4911 scrolling through multibyte text.
4913 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4915 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4916 calling mark_vectorlike since that's the one that marks the window.
4917 (mark_discard_killed_buffers): Mark the final cdr.
4918 * window.h (struct window): Move prev/next_buffers to the
4919 non-standard fields.
4920 * window.c (make_window): Initialize prev/next_buffers manually.
4922 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4924 Omit unused arg EXPECTED from socket hooks.
4925 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4926 * nsterm.m (ns_term_init):
4927 * termhooks.h (struct terminal.read_socket_hook):
4928 * w32inevt.c (w32_console_read_socket):
4929 * w32term.c (w32_read_socket):
4930 * xterm.c (XTread_socket):
4931 Omit unused arg EXPECTED. All callers changed.
4932 (store_user_signal_events): Return void, not int, since callers no
4933 longer care about the return value. All uses changed.
4935 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4937 * w32gui.h (XParseGeometry): Do not declare.
4939 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4941 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4942 Ignore 'expected'. See Eli Zaretskii in
4943 <http://bugs.gnu.org/12471#8> (last line).
4945 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4946 (XParseGeometry): Now static. Substitute extremal values for
4947 values that are out of range.
4949 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4951 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4953 * nsfns.m (XParseGeometry): Remove.
4954 (Fx_create_frame): Call x_set_offset to correctly interpret
4955 top_pos in geometry.
4957 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4958 (Fx_parse_geometry): If there is a space in string, call
4959 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4961 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4963 * search.c (scan_buffer): Use character positions in calls to
4964 region_cache_forward and region_cache_backward, not byte
4965 positions. (Bug#12196)
4967 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4968 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4970 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4971 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4972 emacs_blocked_malloc, now deleted.
4974 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4976 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4977 The workaround was for improving performance on Solaris 2.4, but
4978 is getting in the way now. Emacs will still work if someone is
4979 still running Solaris 2.4 in a museum somewhere; Sun dropped
4980 support for Solaris 2.4 in 2003.
4981 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4982 * process.c (create_process) [HAVE_WORKING_VFORK]:
4983 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4984 since Emacs no longer uses vfork on that platform.
4986 2012-09-17 Glenn Morris <rgm@gnu.org>
4988 * emacs.c: Use COPYRIGHT.
4990 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4992 Remove configure's --without-sync-input option (Bug#12450).
4993 When auditing signal-handling in preparation for cleaning it up,
4994 I found that SYNC_INPUT has race conditions and would be a real
4995 pain to fix. Since it's an undocumented and deprecated
4996 configure-time option, now seems like a good time to remove it.
4997 Also see <http://bugs.gnu.org/11080#16>.
4998 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4999 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5000 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5001 (malloc_hysteresis):
5002 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5003 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5004 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5005 (dont_register_blocks, bytes_used_when_reconsidered)
5006 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5007 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5008 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5009 Remove. All uses removed.
5010 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5011 implementation, one that depends on whether the new macro
5012 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5014 * atimer.c (run_timers, handle_alarm_signal):
5015 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5016 (handle_async_input, process_pending_signals)
5017 (handle_input_available_signal, init_keyboard):
5018 * nsterm.m (ns_read_socket):
5019 * process.c (wait_reading_process_output):
5020 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5021 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5023 * xterm.c (XTread_socket):
5025 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5026 * eval.c (handling_signal): Remove. All uses removed.
5027 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5028 All uses replaced with the SYNC_INPUT version.
5029 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5031 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5034 * font.c (Ffont_shape_gstring): Remove unused local.
5036 2012-09-16 Glenn Morris <rgm@gnu.org>
5038 * Makefile.in (clean): No longer run nextstep's clean.
5040 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5042 (ns-app): Move here from ns.mk, and simplify.
5043 (clean): Simplify nextstep entry.
5044 * ns.mk: Remove file.
5046 2012-09-17 Kenichi Handa <handa@gnu.org>
5048 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5049 not covert the last few charactes.
5051 2012-09-16 Kenichi Handa <handa@gnu.org>
5053 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5054 here, but just check the validity of glyphs in the glyph-string.
5056 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5058 * window.c (Fwindow_parameter, Fset_window_parameter):
5059 Accept any window as argument (Bug#12452).
5061 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5063 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5064 to ns_term_init to avoid memory leak.
5066 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5067 explicit retain/release.
5068 (ns_term_init): Only allow one display. Initialize outerpool and
5071 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5073 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5074 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5075 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5076 the Microsoft problem in a different way, by altering ../nt/config.nt.
5078 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5093 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5094 by lisp.h. This completes removal of setjmp.h inclusion
5095 erroneously announced in the previous commit. (Bug#12446)
5097 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5100 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5101 not defined as a macro. The latter happens on MS-Windows.
5104 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5106 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5107 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5108 Some instances of '#include <setjmp.h>' removed, if the
5109 only reason for the instance was because "lisp.h" was included.
5110 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5111 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5112 and _longjmp with the new symbols. Emacs already uses _setjmp if
5113 available, so this change affects only POSIXish hosts that have
5114 sigsetjmp but not _setjmp, such as some versions of Solaris and
5115 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5116 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5117 (png_load_body) [HAVE_PNG]:
5118 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5119 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5120 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5121 since PNG requires jmp_buf. This is the only exception to the
5122 general rule that we now use sys_setjmp and sys_longjmp.
5123 This exception is OK since this code does not change the signal
5124 mask or longjmp out of a signal handler.
5126 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5128 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5129 Include "syssignal.h", for 'main_thread'.
5131 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5133 Avoid out-of-range marker position (Bug#12426).
5134 * insdel.c (replace_range, replace_range_2):
5135 Adjust markers before overlays, as suggested by comments.
5136 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5137 Remove redundant check before calling offset_intervals.
5139 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5141 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5142 current buffer (Bug#12387).
5144 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5146 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5148 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5150 Use a more backwards-compatible timer format (Bug#12430).
5151 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5152 vector element, not from the 4th, since PSECS is now at the end.
5153 (Fcurrent_idle_time): Doc fix.
5155 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5157 Function to mark objects and remove killed buffers at once.
5158 * alloc.c (discard_killed_buffers): Rename to ...
5159 (mark_discard_killed buffers) ... new name. Add marking
5160 of remaining objects. Fix comment. Adjust users.
5161 (mark_object): Do not touch frame buffer lists here.
5162 * frame.c (delete_frame): Reset frame buffer lists here.
5164 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5166 Better workaround for GNOME bug when --enable-gcc-warnings.
5167 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5168 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5169 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5171 Simplify SIGIO usage (Bug#12408).
5172 The code that dealt with SIGIO was crufty and confusing, e.g., it
5173 played tricks like "#undef SIGIO" but these tricks were not used
5174 consistently. Simplify mostly by not #undeffing standard symbols,
5175 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5176 or not as we please) rather than "defined SIGIO" (standard symbol
5177 that we probably shouldn't #undef).
5178 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5179 Modules that need it can include it.
5180 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5181 * dispextern.h (ignore_sigio): New decl.
5182 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5183 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5184 * emacs.c (shut_down_emacs):
5185 * keyboard.c (kbd_buffer_store_event_hold):
5186 Use ignore_sigio rather than invoking 'signal' directly.
5187 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5189 (FIONREAD, SIGIO): Do not #undef.
5190 (tty_read_avail_input): Use #error rather than a syntax error.
5191 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5192 for I_PIPE, used by SETUP_SLAVE_PTY.
5193 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5194 * sysdep.c (croak): Remove; no longer needed. This bit of
5195 temporary code, with Fred N. Fish's comment that it's temporary,
5196 has been in Emacs since at least 1992!
5197 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5198 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5199 * syssignal.h (croak): Remove decl.
5200 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5201 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5202 now that we're termios-only.
5203 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5204 * term.c (dissociate_if_controlling_tty): Use #error rather than
5207 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5208 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5209 to work around GNOME bug 683906.
5210 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5211 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5212 This works around GCC bug 54561.
5214 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5216 More fixes for 'volatile' and setjmp/longjmp.
5217 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5218 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5219 (png_load_body) [HAVE_PNG]:
5220 (jpeg_load_body) [HAVE_JPEG]:
5221 New function, with most of the old parent function's body.
5222 (png_load) [HAVE_PNG]:
5223 (jpeg_load) [HAVE_JPEG]:
5224 Invoke the new function, to avoid longjmp munging our locals.
5225 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5226 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5227 longjmp is passed 2, as the C standard doesn't guarantee this.
5228 Instead, store the failure code into mgr->failure_code.
5230 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5232 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5233 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5234 (syms_of_keyboard): Remove support for unread-command-char.
5236 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5238 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5239 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5240 violation. (Bug#12426)
5242 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5244 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5246 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5248 * eval.c: Add `inhibit-debugger'.
5249 (Qinhibit_debugger): New symbol.
5250 (call_debugger): Bind it instead of Qdebug_on_error.
5251 (maybe_call_debugger): Test Vinhibit_debugger.
5252 (syms_of_eval): Define inhibit-debugger.
5253 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5254 (syms_of_xdisp): Remove inhibit-debug-on-message.
5256 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5258 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5259 If a nonvolatile local variable is written before a _longjmp to
5260 the frame containing the variable, and is read after the _longjmp,
5261 the value read is indeterminate. Some local variables of type
5262 'struct handler' and 'struct catchtag' are used in this way, so
5263 mark each of their slots as volatile if the slot can be set before
5264 _longjmp and read afterwards.
5265 * lisp.h (struct handler): var and chosen_clause are now volatile.
5266 (struct catchtag): val, next, and pdlcount are now volatile.
5268 * bidi.c (bidi_push_it, bidi_pop_it):
5269 * fns.c (copy_hash_table):
5270 * image.c (define_image_type):
5271 * keyboard.c (kbd_buffer_store_event_hold):
5272 * process.c (Fprocess_send_eof):
5273 * xfaces.c (x_create_gc) [HAVE_NS]:
5274 * xgselect.c (xg_select):
5275 Prefer assignment to memcpy when either will do.
5277 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5278 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5279 time an item is removed. No need to mark this function 'inline';
5280 the compiler knows better than we do.
5282 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5284 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5285 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5286 to change_frame_size (Bug#12388).
5287 (windowDidResize:): Pass YES to updateFrameSize.
5289 * nsterm.h: Add delay parameter to updateFrameSize.
5291 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5293 Discard killed buffers from deleted window and frame objects.
5294 This reduces an amount of references to killed buffers and
5295 helps GC to reclaim them faster.
5296 * alloc.c (discard_killed_buffers): New function.
5297 (mark_object): Use it for deleted windows and frames.
5298 (mark_object): If symbol's value is set up for a killed buffer
5299 or deleted frame, restore its global binding.
5300 * data.c (swap_in_global_binding): Add GC notice.
5301 (swap_in_symval_forwarding): Use convenient set_blv_where.
5302 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5303 * window.h: ... to here.
5305 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5307 Convenient macro to check whether the buffer is live.
5308 * buffer.h (BUFFER_LIVE_P): New macro.
5309 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5310 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5312 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5314 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5315 composition cases (Bug#12364).
5317 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5318 overhang of succeeding glyphs overlapping box cursor.
5320 * w32term.c (x_draw_glyph_string): Likewise.
5322 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5324 Simplify, document, and port floating-point (Bug#12381).
5325 The porting part of this patch fixes bugs on non-IEEE platforms
5326 with frexp, ldexp, logb.
5327 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5329 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5330 support, by removing commented-out code and briefly listing the
5331 C89 functions excluded. The commented-out stuff was confusing
5332 maintenance, e.g., we thought we needed cbrt but it was commented out.
5333 (logb): Remove decl; no longer needed.
5334 (isfinite): New macro, if not already supplied.
5335 (isnan): Don't replace any existing macro.
5336 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5337 are present on all C89 platforms.
5338 (Ffrexp): Do not special-case zero, as frexp does the right thing
5340 (Flogb): Do not use logb, as it doesn't have the desired meaning
5341 on hosts that use non-base-2 floating point. Instead, stick with
5342 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5343 frexp, to avoid getting an unspecified result.
5345 * xdisp.c (Qinhibit_debug_on_message): Now static.
5347 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5349 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5350 NSBezierPath (Bug#12131).
5352 2012-09-10 Chong Yidong <cyd@gnu.org>
5354 * fns.c (Fdelq, Fdelete): Doc fix.
5356 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5358 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5359 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5361 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5363 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5364 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5367 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5369 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5370 left fringe if the window has a left margin. This avoids leaving
5371 traces of the cursor because its leftmost pixel is not drawn over.
5373 * dispnew.c (update_window_line): When the left margin area of a
5374 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5375 that screen line. (Bug#12277)
5377 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5379 Assume C89 or later for math functions (Bug#12381).
5380 This simplifies the code, and makes it a bit smaller and faster,
5381 and (most important) makes it easier to clean up signal handling
5382 since we can stop worring about floating-point exceptions in
5383 library code. That was a problem before C89, but the problem
5384 went away many years ago on all practical Emacs targets.
5385 * data.c, image.c, lread.c, print.c:
5386 Don't include <math.h>; no longer needed.
5387 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5388 might be autoconfigured, as that never happens.
5390 * doprnt.c (DBL_MAX_10_EXP):
5391 * print.c (DBL_DIG):
5392 Remove. C89 or later always defines these.
5393 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5394 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5395 (arith_error, domain_error, domain_error2):
5396 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5397 no longer needed -- we simply return what C returns. All uses removed.
5398 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5400 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5401 Remove. All uses expanded, as these macros are no longer used
5402 more than once and are now more trouble than they're worth.
5403 (Ftan): Use tan, not sin / cos.
5404 (Flogb): Assume C89 frexp.
5405 (fmod_float): Assume C89 fmod.
5406 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5407 (init_floatfns): Remove. All uses removed.
5409 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5411 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5412 compositeToPoint for OSX < 10.6 (Bug#12390).
5414 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5416 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5417 This produces more-accurate results.
5419 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5421 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5422 changes (Bug#12088).
5424 2012-09-08 Chong Yidong <cyd@gnu.org>
5426 * syntax.c (Fstring_to_syntax): Doc fix.
5428 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5430 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5431 in the internal border.
5432 (x_set_window_size): Remove static variables and their usage.
5433 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5434 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5435 Remove fringe/internal border adjustment (Bug#11052).
5436 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5437 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5438 (ns_fix_rect_ibw): Remove.
5439 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5440 (ns_dumpglyphs_box_or_relief): Ditto.
5441 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5443 (ns_dumpglyphs_image): Ditto.
5444 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5446 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5447 their usage. Add fringe_extended_p and its use as in other terms.
5448 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5449 scroll bar was removed.
5450 (updateFrameSize): New function.
5451 (windowDidResize): Move code to updateFrameSize and call it.
5453 * nsterm.h (EmacsView): Add updateFrameSize.
5455 2012-09-07 Chong Yidong <cyd@gnu.org>
5457 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5459 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5461 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5463 More signal-handler cleanup (Bug#12327).
5464 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5465 Problem introduced when merging patches. Noted by Eli Zaretskii in
5466 <http://bugs.gnu.org/12327#67>.
5467 * floatfns.c: Comment fix.
5468 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5469 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5470 and anyway the declaration is harmless even if SIGDANGER is not defined.
5471 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5472 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5473 source files not surprisingly expected syssignal.h to define, or
5474 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5475 Include <sys/ioctl.h>, for FIONREAD.
5476 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5477 This eliminates a problem whereby other files mysteriously had
5478 to include "syssignal.h" before including "systty.h" if they
5479 wanted to use "#ifdef SIGIO".
5481 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5483 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5485 * w32.c (sigemptyset): Empty the set.
5486 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5488 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5490 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5492 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5493 (mark_object): Likewise for frame objects.
5495 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5497 * syssignal.h (handle_on_main_thread): Always declare,
5498 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5499 This ports to platforms without HAVE_PTHREAD.
5501 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5503 Signal-handler cleanup (Bug#12327).
5504 Emacs's signal handlers were written in the old 4.2BSD style with
5505 sigblock and sigmask and so forth, and this led to some
5506 inefficiencies and confusion. Rewrite these to use
5507 pthread_sigmask etc. without copying signal sets around. Also,
5508 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5509 'signal', and instead use functions that do not attempt to take
5510 over the system name space. This patch causes Emacs's text
5511 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5512 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5513 Do not include <signal.h> or "syssignal.h", as these
5514 modules do not use signals.
5515 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5516 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5517 Do not include <signal.h>, as "syssignal.h" does that for us now.
5518 * atimer.c (sigmask_atimers): New function.
5519 (block_atimers, unblock_atimers): New functions,
5520 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5522 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5523 no longer needed here.
5524 * emacs.c (main): Inspect existing signal handler with sigaction,
5525 so that there's no need to block and unblock SIGHUP.
5526 * sysdep.c (struct save_signal): New member 'action', replacing
5527 old member 'handler'.
5528 (save_signal_handlers, restore_signal_handlers):
5529 Use sigaction instead of 'signal' to save and restore.
5530 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5531 New function. All users of 'signal' modified to use set_sighandler
5532 if they're writeonly, and to use sys_signal if they're read+write.
5533 (emacs_sigaction_init, forwarded_signal): New functions.
5534 (sys_signal): Remove. All uses replaced by calls to sigaction
5535 and emacs_sigaction_init, or by direct calls to 'signal'.
5536 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5537 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5538 all uses replaced by pthread_sigmask etc. calls.
5539 * syssignal.h: Include <signal.h>.
5540 (emacs_sigaction_init, forwarded_signal): New decls.
5541 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5542 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5543 (sigmask, sys_sigmask): Remove; no longer needed.
5544 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5545 (sigblock, sigunblock, sigfree):
5546 (sigsetmask) [!defined sigsetmask]:
5547 Remove. All uses replaced by pthread_sigmask.
5548 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5549 no longer need to be replaced, and its typical old uses
5550 are now done via emacs_sigaction_init and sigaction.
5551 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5552 (sys_sigdel): Remove; unused.
5553 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5555 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5557 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5558 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5560 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5562 Explicitly mark buffer_defaults and buffer_local_symbols.
5563 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5564 mark_local_symbols here.
5565 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5566 since special buffers aren't marked here any more.
5567 (allocate_buffer): Chain new buffer with all_buffers here...
5568 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5570 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5571 (syms_of_buffer): Remove staticpro of the above.
5572 (init_buffer_once): Set names for buffer_defaults and
5573 buffer_local_symbols.
5575 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5577 Use bool for booleans in font-related modules.
5578 * font.c (font_intern_prop, font_style_to_value)
5579 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5580 (generate_otf_features, font_check_otf_features, font_check_otf)
5581 (font_match_p, font_list_entities, font_at):
5582 * fontset.c (fontset_id_valid_p, reorder_font_vector
5583 (fontset_find_font, Fset_fontset_font)
5584 (face_suitable_for_char_p) [0]:
5585 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5586 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5587 (m17n_flt_initialized, ftfont_shape_by_flt):
5588 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5589 * nsfont.m (nsfont_draw):
5590 * w32font.c (w32font_draw):
5591 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5592 Use bool for booleans.
5593 * font.h: Adjust to above API changes.
5594 (struct font, struct font_driver, struct font_driver_list):
5595 Use bool for booleans.
5596 (struct font): Remove useless member encoding_type.
5598 * fontset.c, xftfont.c: Omit unnecessary static decls.
5600 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5602 * alloc.c (mark_object): Revert window marking code
5603 since it's unsafe for the Fset_window_configuration.
5605 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5607 Fix race conditions with signal handlers and errno (Bug#12327).
5608 Be more systematic about preserving errno whenever a signal
5609 handler returns, even if it's not in the main thread. Do this by
5610 renaming signal handlers to distinguish between signal delivery
5611 and signal handling. All uses changed.
5612 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5613 * data.c (deliver_arith_signal): Rename from arith_error.
5614 * dispnew.c (deliver_window_change_signal): Rename from
5615 window_change_signal.
5616 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5617 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5618 * keyboard.c (deliver_input_available_signal): Rename from
5619 input_available_signal.
5620 (deliver_user_signal): Rename from handle_user_signal.
5621 (deliver_interrupt_signal): Rename from interrupt_signal.
5622 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5623 (deliver_child_signal): Rename from sigchld_handler.
5624 * atimer.c (handle_alarm_signal):
5625 * data.c (handle_arith_signal):
5626 * dispnew.c (handle_window_change_signal):
5627 * emacs.c (handle_fatal_signal, handle_danger_signal):
5628 * keyboard.c (handle_input_available_signal):
5629 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5630 * process.c (handle_pipe_signal, handle_child_signal):
5631 New functions, with the actual signal-handling code taken from the
5632 original respective signal handlers, sans the sporadic attempts to
5633 preserve errno, since that's now done by handle_on_main_thread.
5634 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5635 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5636 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5638 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5639 Move initialization of main_thread to sysdep.c's init_signals.
5640 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5641 our usage, and simplifies the mainline code.
5642 (record_child_status_change): New static function, as a helper
5643 for handle_child_signal, and with most of the old child handler's
5645 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5646 (handle_child_signal): Use the above.
5647 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5648 Moved here from emacs.c.
5649 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5650 code moved here from emacs.c's main function.
5651 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5652 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5653 This lets callers save and restore errno properly.
5655 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5657 Remove redundant or unused things here and there.
5658 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5659 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5660 * editfns.c (Fcompare_buffer_substrings): Likewise.
5661 * frame.h (struct terminal, struct font_driver_list):
5662 Remove redundant declarations.
5663 * window.h (Qleft, Qright): Likewise.
5665 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5667 Do not mark objects from deleted buffers, windows and frames.
5668 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5669 (mark_object): Likewise for windows and frames.
5671 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5673 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5674 buffer_defaults and buffer_local_symbols as valid objects.
5675 Return special value to denote them.
5677 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5679 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5680 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5681 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5682 (file_name_absolute_p, Fsubstitute_in_file_name):
5683 (check_executable, check_writable, Ffile_accessible_directory_p)
5684 (Fset_file_selinux_context, Fdefault_file_modes)
5685 (Finsert_file_contents, choose_write_coding_system)
5686 (Fwrite_region, build_annotations, a_write, e_write)
5688 * filelock.c (boot_time_initialized, get_boot_time)
5689 (get_boot_time_1, lock_file_1, within_one_second):
5690 * floatfns.c (in_float):
5691 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5692 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5693 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5694 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5695 * window.c (compare_window_configurations):
5696 Use bool for booleans.
5697 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5698 (Fdefault_file_modes): Now mode_t, not int, for modes.
5699 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5700 (internal_delete_file): Now returns void, not a (boolean) int,
5701 since nobody was looking at the return value.
5702 * lisp.h, window.h: Adjust to above API changes.
5704 * xdisp.c (set_message): Simplify and reindent last change.
5706 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5708 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5710 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5712 * eval.c (call_debugger): Make the function non-static so that we
5713 can call it from set_message.
5715 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5716 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5718 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5720 Give more-useful info on a fatal error (Bug#12328).
5721 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5722 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5723 of doing the work ourselves.
5724 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5725 do most of the work.
5726 (fatal_error_backtrace): New function, taken from the guts
5727 of the old fatal_error_signal, but with a new option to output
5729 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5730 info about the signal than just its number.
5731 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5732 * sysdep.c: Include <execinfo.h>
5733 (emacs_backtrace): New function, taken partly from the previous
5734 code of the 'die' function.
5735 (emacs_abort): Call fatal_error_backtrace rather than abort.
5737 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5739 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5740 eager (load-time) macro-expansion.
5741 * lisp.mk (lisp): Add macroexp.
5743 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5745 Simplify redefinition of 'abort' (Bug#12316).
5746 Do not try to redefine the 'abort' function. Instead, redo
5747 the code so that it calls 'emacs_abort' rather than 'abort'.
5748 This removes the need for the NO_ABORT configure-time macro
5749 and makes it easier to change the abort code to do a backtrace.
5750 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5751 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5752 Remove; sysdep.c's emacs_abort now takes its place.
5753 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5754 'abort' changed to use 'emacs_abort'.
5755 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5756 (abort) [!defined abort]: Rename to ...
5757 (emacs_abort): ... new name.
5758 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5759 the place of the old 'abort' in emacs.c.
5760 * w32.c, w32fns.c (abort): Do not #undef.
5761 * w32.c (emacs_abort): Rename from w32_abort.
5763 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5765 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5766 offsets[j].dv, since the y axis of the screen coordinates points
5767 down, while the y axis of the font definition coordinates points
5768 up. This fixes display of Arabic diacritics such as KASRA and
5769 KASRATAN. (Bug#11860)
5771 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5773 Be more systematic about _setjmp vs setjmp.
5774 * alloc.c (test_setjmp, mark_stack):
5775 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5776 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5777 (png_load, my_error_exit, jpeg_load):
5778 * process.c (send_process_trap, send_process):
5779 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5780 The underscored versions are up to 30x faster on some hosts.
5781 Formerly, the code used setjmp+longjmp sometimes and
5782 _setjmp+_longjmp at other times, with no particular reason to
5783 prefer setjmp+longjmp.
5785 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5787 Fix minor problem found by static checking.
5788 * buffer.c (Fdelete_all_overlays): Return nil.
5790 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5792 * buffer.c (Fdelete_all_overlays): New function.
5794 2012-09-03 Chong Yidong <cyd@gnu.org>
5796 * gtkutil.c: Add extern decl for Qxft.
5798 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5800 * emacs.c, eval.c: Use bool for boolean.
5801 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5802 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5803 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5804 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5805 (main, decode_env_path, Fdaemon_initialized):
5806 * eval.c (call_debugger, Finteractive_p, interactive_p):
5807 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5808 (maybe_call_debugger, Fbacktrace):
5809 * process.c (read_process_output, exec_sentinel):
5810 Use bool for booleans.
5811 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5812 All callers changed.
5813 * eval.c (interactive_p): Omit always-true boolean argument
5814 EXCLUDE_SUBRS_P. All callers changed.
5815 * dispextern.h, lisp.h: Reflect above API changes.
5816 * firstfile.c (dummy): Use the address of 'main', whose signature
5817 won't change, instead of the address of 'initialize', whose
5818 signature just changed from int to bool.
5819 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5820 * msdos.c (fatal_error_in_progress): ... from here.
5821 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5823 (redisplay_internal, unwind_redisplay): Simply clear
5824 REDISPLAYING_P when unwinding, instead of saving its previous,
5825 always-false value and then restoring it.
5827 Clean up some extern decls.
5828 Mostly, this hoists extern decls out of .c files and into .h files.
5829 That way, we're more likely to catch errors if the interfaces change.
5830 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5831 declare xg_mark_data.
5832 * dispextern.h (x_frame_parm_handlers):
5834 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5835 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5836 (Qultra_bold, Qoblique, Qitalic):
5837 Move extern decl here from .c file.
5838 * alloc.c (xg_mark_data) [USE_GTK]:
5840 * eval.c (Qlexical_binding):
5841 * fns.c (time) [!HAVE_UNISTD_H]:

5847 * process.c (QCfamily, QCfilter):
5848 * widget.c (free_frame_faces):
5849 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5850 * xfont.c (x_clear_errors):
5851 * xterm.c (x_frame_parm_handlers):
5852 Remove now-redundant extern decls.
5853 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5854 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5856 * xfaces.c: Remove unnecessary static decls.
5857 * xterm.c (updating_frame): Remove decl of nonexistent object.
5859 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5860 when building globals.h, as the objects that are not built on
5861 this host are not needed to compile C files on this host.
5863 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5865 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5867 * frame.h: Add missing prototype for x_wm_set_size_hint.
5869 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5871 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

5873 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5874 (Fsubstitute_command_keys):

5879 (make_buffer_string, make_buffer_string_both)
5880 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5892 (set_intervals_multibyte_1, set_intervals_multibyte):
5893 * keyboard.c (decode_timer):
5894 Use bool for boolean.
5895 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5896 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5898 2012-09-02 Chong Yidong <cyd@gnu.org>
5900 * keymap.c (push_key_description): Print M-TAB as C-M-i
5903 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5905 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5906 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5907 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5911 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5913 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5915 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5916 more than one grapheme cluster passed to the shaper: compute the
5917 offset adjustment values separately for each cluster. (Bug#11860)
5919 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5920 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5921 about implicit conversions from integer to pointer.

6240 Special MEM_TYPE_SPARE to denote reserved memory.
6241 * alloc.c (enum mem_type): New memory type.
6242 (refill_memory_reserve): Use new type for spare memory.

6276 * character.h, charset.h: Adjust to match previous changes.
6277 * character.h (char_printable_p): Remove decl of nonexistent function.
6278 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6279 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6280 are all boolean, so make them single-bit bitfields.
6282 * lisp.h (ASET): Remove attempt to detect side effects.
6283 It was meant to be temporary and it often doesn't work,
6284 because when IDX has side effects the behavior of IDX==IDX
6285 is undefined. See Stefan Monnier in
6286 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6288 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6291 (FUNCTIONP): Use it.

6296 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6297 as that's faster and simpler than static storage. Don't bother
6298 with the g_main_context_query overhead if g_main_context_pending
6299 says no events are pending.
6300 (gfds, gfds_size): Remove these static vars.
6301 (xgselect_initialize): Remove; no longer needed.
6302 All uses and decls removed.
6304 * emacs.c (fatal_error_signal_hook): Remove.
6305 All uses removed. This leftover from old code was always 0.
6307 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

6332 Use bool for booleans, instead of int.
6333 * lisp.h, process.h: Adjust prototypes to match above changes.
6334 * callint.c (Fcall_interactively): Don't assume the mark's
6335 offset fits in 'int'.

6348 Use bool for booleans, instead of int.
6349 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6350 since the 1-or-0 return value is always ignored anyway.
6351 (mmap_initialized_p):
6352 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6353 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6355 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6357 * bidi.c: Use bool for boolean.
6358 This is a bit more readable, and makes the text segment of bidi.o
6359 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6360 Presumably it's faster too.

6377 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6379 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6380 * atimer.h: Include <stdbool.h>.
6382 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6384 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6385 compile time tests instead of run time tests on systems that do
6387 (FRAME_MAC_P): Remove leftover from deleted code.
6388 * frame.c (syms_of_frame): Remove leftover from deleted code.
6390 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6394 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6396 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6397 Otherwise, the compiler complains about (A?B:C) where B is void
6398 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6399 (fontset_add): Return void, for FONTSET_ADD.
6401 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6403 * alloc.c: Use bool for booleans.
6404 (gc_in_progress, abort_on_gc)
6405 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6406 (dont_register_blocks) [GC_MALLOC_CHECK]:
6407 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6408 (check_string_bytes, make_specified_string, memory_full)
6409 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6410 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6411 (mark_stack, valid_pointer_p, make_pure_string)
6412 (Fgarbage_collect, survives_gc_p, gc_sweep):
6413 Use bool for booleans, instead of int.
6414 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6415 Remove unused local.
6416 * alloc.c (PURE_POINTER_P):
6417 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6418 * editfns.c (Fformat):
6419 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6421 * fns.c (sweep_weak_table):
6422 * lisp.h (suppress_checking, push_message, survives_gc_p)
6423 (make_pure_string, gc_in_progress, abort_on_gc):
6424 * lread.c (readchar, read1):
6425 * print.c (Fprin1_to_string):
6426 * xdisp.c (push_message):
6427 Use bool for booleans affected directly or indirectly by
6430 Make recently-introduced setters macros.
6431 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6432 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6433 (set_fontset_default, set_fontset_fallback): Rename from their
6434 upper-case counterparts, and make them functions rather than macros.
6435 This is more consistent with the other recently-introduced setters.
6436 These don't need to be inline, since they're local.
6438 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6440 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6441 the loop (Bug#12247).
6443 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6445 * lisp.h (vcopy): Use memcpy rather than our own loop.
6446 This fixes a performance regression introduced by the recent
6447 addition of vcopy. This means 'vcopy' will need to be modified
6448 for a copying collector, but that's OK. Also, tighten the
6449 checking in the assertion.
6451 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6453 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6454 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6455 non-base glyph for the width of the base character, according to
6456 what x_draw_composite_glyph_string_foreground expects.
6457 Generate WADJUST value according to composition_gstring_width's
6458 expectations, to produce correct width of the composed character.
6459 Reverse the sign of the DU offset produced by ScriptPlace.
6461 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6463 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6465 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6467 Avoid direct writes to contents member of struct Lisp_Vector.
6468 * lisp.h (vcopy): New function to copy data into vector.
6469 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6470 * fns.c (Ffillarray): Use ASET.
6471 * keyboard.c (timer_check_2): Use AREF and ASET.
6472 (append_tool_bar_item, Frecent_keys): Use vcopy.
6473 * lread.c (read_vector): Use ASET.
6474 * msdos.c (Frecent_doskeys): Use vcopy.
6475 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6476 (Finternal_merge_in_global_face): Use ASET and vcopy.
6477 * xfont.c (xfont_list_pattern): Likewise.
6479 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6481 * window.c (Fwindow_point): For the selected window always return
6482 the position of its buffer's point.
6483 (Fset_window_point): For the selected window always go in its
6484 buffer to the specified position.
6486 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6488 Setter macros for fontsets.
6489 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6490 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6491 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6494 2012-08-20 Glenn Morris <rgm@gnu.org>
6496 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6497 Don't assume that `ln -f' works.
6499 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6501 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6502 and later about non-assignments with no effect. See discussion at
6503 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6506 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6508 Inline setter functions for Lisp_Objects slots of struct specbinding.
6509 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6512 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6514 * window.c (select_window): Always make selected window's buffer
6517 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6519 Use AREF and ASET for docstrings of category tables.
6520 * category.h (CATEGORY_DOCSTRING): Use AREF.
6521 (SET_CATEGORY_DOCSTRING): Use ASET.
6522 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6524 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6526 Inline setter functions for hash table members.
6527 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6528 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6529 (set_hash_key_and_value, set_hash_index, set_hash_next)
6530 (set_hash_hash): New functions.
6531 * charset.c, fns.c: Adjust users.
6533 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6535 Inline getter and setter functions for per-buffer values.
6536 * buffer.h (per_buffer_default, set_per_buffer_default)
6537 (per_buffer_value, set_per_buffer_value): New functions.
6538 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6539 * buffer.c, data.c: Adjust users.
6541 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6543 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6545 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6547 Rely on <config.h> + <unistd.h> to declare 'environ',
6548 as gnulib does this if the system doesn't.
6549 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6550 Remove declaration. MS-Windows declares it on stdlib.h which is
6551 included by conf_post.h.
6552 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6553 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6554 * vm-limit.c: Include <unistd.h>, for 'environ'.
6556 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6557 (start_of_data): Remove decl; mem-limits.h provides it.
6559 * xdisp.c (handle_invisible_prop): Make it a bit faster
6560 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6562 2012-08-19 Chong Yidong <cyd@gnu.org>
6564 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6567 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6569 * .gdbinit: Use call instead of set when calling a function in the
6572 * data.c (set_internal): Don't use set_blv_found.
6573 (Fkill_local_variable): Likewise.
6575 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6577 * nsfont.m (ns_ascii_average_width): Ensure the string
6578 ascii_printable is initialized with a null-terminated character
6579 array. Otherwise, it can contain undesired extra characters.
6581 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6583 port new setting code to Sun C 5.8 2005/10/13
6584 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6585 Return void, not Lisp_Object. Otherwise, the compiler
6586 complains about (A?B:C) where B is void and C is Lisp_Object
6587 when compiling CHAR_TABLE_SET, due to the recent change to
6588 the API of sub_char_table_set_contents.
6590 2012-08-18 Chong Yidong <cyd@gnu.org>
6592 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6593 for the string case (Bug#3874).

6748 The old version was confusing because it used the same name
6749 'parent' for two different things.
6751 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6753 Functions to get and set Lisp_Object fields of buffer-local variables.

6762 font spec, make the font's attributes take precedence over
6763 directly-specified attributes.
6764 (merge_face_ref): Recognize :font.
6766 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

7420 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7421 * w32.c (init_environment): Change the default values of many
7422 environment variables in dflt_envvars[] to NULL, to avoid pushing
7423 them into environment when they were not already defined.
7424 Remove the code that deletes site-lisp subdirectories from the default
7425 value of EMACSLOADPATH, as it is no longer needed.
7426 (check_windows_init_file): Now external, not static.
7427 Use Vload_path as is, without adding anything, as this function is now
7428 called when Vload_path is already set up.
7430 * w32.h (check_windows_init_file): Add prototype.
7432 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7439 installation tree, as appropriate.
7441 * callproc.c (init_callproc_1): Call decode_env_path instead of
7442 doing its equivalent by hand.

7444 the code that sets Vexec_path run on MS-Windows.
7446 * lread.c (init_lread): Add comments to #ifdef's.
7448 * msdos.c (dos_set_window_size, IT_update_begin)

7460 Remove unnecessary casts involving pointers.
7461 These casts are no longer needed now that we assume C89 or later,

7475 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7476 Remove unnecessary pointer casts.
7477 * alloc.c (record_xmalloc): New function.
7478 * lisp.h (record_xmalloc): New decl.
7479 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7480 more like a function. This is because the pointer cast is not
7481 needed. All uses changed.
7482 * print.c (print_string, print_error_message): Avoid length recalc.
7484 Improve fix for macroexp crash with debugging (Bug#12118).
7485 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7486 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7487 not supposed to be invoked from the garbage collector.
7488 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7489 (gc_aset): New function, which is like ASET but can be
7490 used in the garbage collector.
7491 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7506 headers (most versions of MinGW w32api don't).
7507 (get_security_info, create_symbolic_link)
7508 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

7519 with addition of handling of symlinks and support for 'lstat'.
7520 If possible, get file's attributes and security information by
7521 handle, not by name. Produce S_IFLNK bit for symlinks, when
7522 called from 'lstat'.
7523 (stat, lstat): New functions, call 'stat_worker'.
7524 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7525 symlinks when the underlying filesystem supports them.
7527 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7529 Fix macroexp crash on Windows with debugging (Bug#12118).
7530 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7531 checking subscripts; problem introduced with the recent
7532 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7533 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7534 since it's used in non-static inline functions now.
7536 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7537 Don't assume buffer size fits in 'int'. Remove unused local.

7554 * category.c (CATEGORY_INLINE):
7555 * character.c (CHARACTER_INLINE):
7556 * charset.c (CHARSET_INLINE):
7557 * composite.c (COMPOSITE_INLINE):
7558 * dispnew.c (DISPEXTERN_INLINE):
7559 * sysdep.c (SYSTIME_INLINE):
7560 Define to EXTERN_INLINE, so that the corresponding functions
7561 are compiled into code.
7562 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7563 (INLINE_HEADER_END): New macros.
7564 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7584 hard-coding the path separator.
7586 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7588 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7589 This how ASET and AREF are supposed to work, and makes
7590 it easier to think about future improvements. See
7591 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7592 * charset.h (set_charset_attr): New function.

7974 (w32_kbd_patch_key, key_event): Use the codepage returned by
7975 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

8084 the fix for 12036 would have avoided some of the problems noted in
8085 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8086 would have been more obvious.

8096 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8097 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8098 not be usable in #if. This simplifies things.
8100 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8102 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8107 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8108 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8109 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8110 Adjust to changes in lisp.h and emacs.c, by using

8113 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

8115 instead of gdb_valbits.
8116 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8117 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8118 instead of gdb_array_mark_flag.
8119 (xboolvector): Get size from $->size, not $->header.size.
8120 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8121 (xreload, hook-run, hookpost-run): Remove.
8122 * emacs.c: Include <verify.h>.
8123 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8124 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):

9015 (menu_separator_name_p):

9017 Prefer memcmp to strncmp when either will do.
9018 * nsterm.m: Include <ftoastr.h>.
9020 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9021 Prefer snprintf to strncpy.
9022 * nsterm.m (ns_term_init):
9023 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9024 * nsterm.m (ns_term_init):
9025 Avoid the need for strncpy, by using build_string or
9026 make_unibyte_string directly. Use dtoastr, not snprintf.
9027 * process.c (Fmake_network_process): Diagnose service names that
9028 are too long, rather than silently truncating them or creating
9029 non-null-terminated names.

9059 Optimize pure C strings initialization.
9060 * lisp.h (make_pure_string): Fix prototype.
9061 (build_pure_c_string): New function, defined as static inline. This
9062 provides a better opportunity to optimize away calls to strlen when
9063 the function is called with compile-time constant argument.
9064 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9065 argument, adjust users accordingly. Use build_pure_c_string where
9067 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9068 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9069 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9071 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9073 Avoid calls to strlen in miscellaneous functions.
9074 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

9096 * s/gnu.h (DATA_START): Move definitions to configure.
9098 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9099 We include usg5-4-common.h, which defines them both.
9101 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9102 O_RDONLY already includes it).
9104 Stop ns builds setting the EMACSLOADPATH environment variable.
9105 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9106 Now it does not set EMACSLOADPATH, just returns the load-path string.
9107 * nsterm.h: Update accordingly.
9108 * lread.c [HAVE_NS]: Include nsterm.h.
9109 (init_lread) [HAVE_NS]: Use ns_load_path.

9112 2012-07-09 Glenn Morris <rgm@gnu.org>
9114 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9115 since the included bsd-common.h does so.
9117 Stop ns builds setting the EMACSPATH environment variable.
9118 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9119 (ns_init_paths): Do not set EMACSPATH.
9120 * nsterm.h (ns_exec_path): Add it.
9121 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9124 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9126 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9128 * process.c (wait_reading_process_output): 'waitchannels' was unset
9129 when read_kbd || !NILP (wait_for_cell); fix this.
9131 Add GCC-style 'const' attribute to functions that can use it.
9132 * character.h (char_resolve_modifier_mask):
9133 * keyboard.h (make_ctrl_char):
9134 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9143 Add decls with ATTRIBUTE_CONST.
9145 Minor improvements to make_formatted_string.
9146 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9147 where int is good enough, as vsprintf returns an int.
9148 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9150 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9152 Use make_formatted_string to avoid double length calculation.
9153 * lisp.h (make_formatted_string): New prototype.

9177 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9179 Move marker debugging code under MARKER_DEBUG.
9180 * marker.c (MARKER_DEBUG): Move marker debugging code under
9181 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9182 for bootstrap with --enable-checking (~3x slowdown reported
9183 by Juanma Barranquero <lekktu@gmail.com>).
9184 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9186 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9188 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9189 See <http://bugs.gnu.org/11825#29>.
9191 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9193 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9194 has no font, use the frame's font. (Bug#11813)
9195 (display_line): Add commentary about displaying truncation glyphs
9197 (produce_special_glyphs): Move here from term.c.
9199 * term.c (produce_special_glyphs): Move to xdisp.c.
9201 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9204 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9206 * xdisp.c (display_line): Avoid warning about implicit declaration
9209 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9211 * lisp.h: Remove empty conditional.
9213 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9215 * lread.c (load_path_check): Now static.
9217 Fix some minor --with-ns problems found by static checking.
9218 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9219 (x_set_font) [!HAVE_X_WINDOWS]:
9220 * image.c (xpm_load_image) [HAVE_NS]:
9221 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9222 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9223 Remove unused local.
9224 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9225 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9226 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9227 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9228 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9229 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9230 Fix pointer signedness problem.

9232 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9234 2012-07-07 Glenn Morris <rgm@gnu.org>
9236 * lread.c (load_path_check): New function, split from init_lread.
9237 (init_lread): Reorganize. Motivation:
9238 If EMACSLOADPATH is set, check/warn about that rather than the
9239 defaults, which we are not going to use. Hence we can remove
9240 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9241 Don't warn if site-lisp directories are missing.
9242 If not installed, start from a blank load-path, since
9243 PATH_LOADSEARCH refers to the eventual installation directories.
9245 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9247 Support truncation and continuation glyphs on GUI frames, when
9248 fringes are disabled. (Bug#11832)
9249 * xdisp.c (init_iterator): Get dimensions of truncation and
9250 continuation glyphs even if on GUI frames.
9251 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9252 or both, are absent.
9253 (start_display, move_it_in_display_line_to): Handle the case of a
9254 GUI frame without a fringe to display continuation or truncation
9256 (insert_left_trunc_glyphs): Support GUI frames: make sure
9257 truncation glyphs overwrite enough glyphs from the current line to
9258 have sufficient space in pixels.
9259 (display_line): Support truncation and continuation glyphs on GUI
9260 frames. If some spare pixels are left on the line after inserting
9261 the truncation glyphs, fill that space with a stretch glyph of a
9262 suitably computed width.
9264 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9265 produce_glyphs, to support GUI sessions.
9267 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9269 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9271 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9273 Do not require float-time's arg to fit in time_t (Bug#11825).
9274 This works better on hosts where time_t is unsigned, and where
9275 float-time is applied to the (negative) difference between two times.
9276 * editfns.c (decode_time_components): Last arg is now double *,
9277 not int *, and means to store all the result as a double, without
9278 worrying about whether the seconds part fits in time_t.
9279 All callers changed.
9280 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9281 All callers changed.
9282 (Ffloat_time): Do not fail merely because the specified time falls
9283 outside of time_t range.
9285 2012-07-07 Glenn Morris <rgm@gnu.org>
9287 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9302 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9303 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9304 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

9307 * xfont.c (compare_font_names): Redo to omit the need for casts.
9309 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9311 * xfns.c (Fx_change_window_property): Doc fix.
9312 * w32fns.c (Fx_change_window_property): Doc fix.
9314 * w32fns.c (Fx_window_property): Accept the same arguments as the
9315 X Windows version. Doc fix.
9316 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9318 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9319 Eli Zaretskii <eliz@gnu.org>
9321 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9322 Windows-specific code from nt/config.nt moved here.
9323 Obsolete settings removed.
9325 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9327 * process.c: Avoid unnecessary calls to gettime.
9328 (wait_reading_process_output): Don't get the time of day
9329 when gobbling data immediately and not waiting, as there's no need
9330 for it in that case. This removes a FIXME.
9332 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9334 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9335 is defined (Bug#11768).
9337 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9339 Fix marker debugging code.
9340 * marker.c (byte_char_debug_check): Do not perform the check
9341 if buffer is not multibyte.
9342 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9343 Call byte_char_debug_check with correct arguments.
9345 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9347 Compile marker debugging code only if ENABLE_CHECKING is defined.
9348 * marker.c (byte_char_debug_check, count_markers):
9349 Use only if ENABLE_CHECKING is defined.
9350 (byte_debug_flag): Remove.
9351 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9352 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9354 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9356 Avoid code repetition in marker-related functions.
9357 * marker.c (attach_marker): New function.
9358 (Fset_marker, set_marker_restricted, set_marker_both)
9359 (set_marker_restricted_both): Use it.
9360 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9361 Consistently rename charno to charpos.
9362 (marker_position): Add eassert.
9363 (marker_byte_position): Convert to eassert.

9382 * window.c (save_window_save): Likewise.
9384 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9386 Do not use Fdelete_overlay in delete_all_overlays
9387 to avoid redundant calls to unchain_overlay.
9388 * buffer.c (drop_overlay): New function.
9389 (delete_all_overlays, Fdelete_overlay): Use it.
9390 * minibuf.c (get_minibuffer): Fix comment.
9392 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9394 Port to OpenBSD 5.1 amd64.
9395 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9396 This is needed for OpenBSD, and should be harmless on all BSD systems.
9397 Also, include <sys/sysctl.h>, as it should be available on all
9398 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9399 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9400 use p_pid member, not kp_proc.pid.
9402 2012-07-06 Glenn Morris <rgm@gnu.org>
9404 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9406 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9408 More xmalloc and related cleanup.

9417 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9419 Omit needless casts involving void * pointers and allocation.
9420 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9421 as the former is more robust if P's type is changed.
9422 Prefer xzalloc to xmalloc + memset 0.
9423 Simplify malloc-or-realloc to realloc.
9424 Don't worry about xmalloc returning a null pointer.
9425 Prefer xstrdup to xmalloc + strcpy.
9426 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9428 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9429 alloca of a constant.
9431 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9433 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9434 hscroll is larger than the line width. Fixes long and futile
9435 looping inside extend_face_to_end_of_line (on a TTY) producing
9436 glyphs that are not needed and thrown away.
9438 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9440 * marker.c (set_marker_restricted_both): Simplify by using
9443 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9466 * xdisp.c (window_hscroll_limited): New function.
9467 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9468 coordinates when window's hscroll is set to insanely large

9534 * fileio.c (time_error_value): Check the right error number.
9535 Problem reported by Troels Nielsen in
9536 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9538 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9540 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9541 This should be fixed in a better way; see Eli Zaretskii in
9542 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9543 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9545 * fileio.c (time_error_value): Rename from special_mtime.
9546 The old name's problems were noted by Eli Zaretskii in
9547 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9549 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9550 This variable's comment says Emacs needs at least one GDB-visible
9551 symbol of type enum pvec_type, to work around GDB problems.
9552 The symbol's value doesn't matter.
9554 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9555 that causes compilation to fail on pre-C99 compilers.
9557 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9559 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9560 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9562 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9564 * buffer.c (init_buffer_once): Fix initialization of
9565 headers for buffer_defaults and buffer_local_symbols.
9566 Reported by Juanma Barranquero <lekktu@gmail.com>.
9568 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9570 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9571 * lisp.h (enum pvec_type): Use fewer bits.
9572 (PSEUDOVECTOR_SIZE_BITS): New constant.
9573 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9574 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9575 change in pvec_type.
9576 (PSEUDOVECTOR_TYPEP): New macro.
9577 (TYPED_PSEUDOVECTORP): Use it.
9578 * fns.c (internal_equal): Adapt code to extract pvectype.

9580 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9581 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9582 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9583 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9584 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9585 abusing vector->header.next.nbytes.
9586 (live_vector_p): Use PVEC_TYPE.
9587 (mark_object): Adapt code to extract pvectype. Use switch.
9589 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9591 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9592 Tighten new eassert a bit.
9594 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9596 Fix compilation with --enable-gcc-warnings and -O1
9598 * doprnt.c (doprnt): Change type of tem to int, initialize
9599 to avoid compiler warning. Add eassert.
9600 * search.c (simple_search): Initialize match_byte to avoid
9601 compiler warning. Add eassert.
9603 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9605 Avoid weird behavior with large horizontal scrolls.
9606 Without this change, for example, large hscroll values would
9607 mess up Emacs's display on Fedora 15 x86, presumably due to
9608 overflows in int calculations in the display code.
9609 Also, if buffers had long lines, Emacs would freeze.
9610 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9611 (set_window_hscroll): New function, containing the old guts of
9612 Fset_window_hscroll. Return the clipped value.
9613 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9614 This avoids the need to check against PTRDIFF_MAX.
9616 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9618 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9620 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9622 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9624 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9625 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9626 since GCC 4.4.6 issues a bogus warning for them.
9628 Fix bugs in file timestamp newness comparisons.
9629 * fileio.c (Ffile_newer_than_file_p):
9630 * lread.c (Fload): Use full timestamp resolution of files,
9631 not just the 1-second resolution, so that files that are only
9632 slightly newer still count as newer.
9633 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9634 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9636 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9638 * fileio.c: Improve handling of file time marker. (Bug#11852)
9639 (special_mtime): New function.
9640 (Finsert_file_contents, Fverify_visited_file_modtime):
9641 Use it to set special mtime values consistently.
9643 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9645 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9646 marker for non-existing file. (Bug#11852)
9648 2012-07-03 Glenn Morris <rgm@gnu.org>
9650 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9651 and did not make it into globals.h).
9653 2012-07-03 Tom Tromey <tromey@redhat.com>
9655 * window.c (Fset_window_margins, Fset_window_fringes)
9656 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9657 * textprop.c (Fprevious_property_change): No longer static.
9658 * syntax.c (Fsyntax_table_p): No longer static.
9659 * process.c (Fget_process, Fprocess_datagram_address): No longer

9680 * intervals.h: Remove EXFUNs.
9681 * fontset.h: Remove EXFUN.

9686 * w32term.h: Remove EXFUNs.
9687 * window.h: Remove EXFUNs.
9688 * xsettings.h: Remove EXFUN.
9689 * xterm.h: Remove EXFUN.
9691 2012-07-03 Glenn Morris <rgm@gnu.org>
9693 * lisp.h (Frandom): Make it visible to C.
9694 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9695 buffer for invisible buffers. (Bug#1229)
9697 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9699 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9700 values which aren't power of 2.
9701 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9702 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9705 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9707 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9709 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9711 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9713 * alloc.c (allocate_vector_block): Remove redundant
9714 calls to mallopt if DOUG_LEA_MALLOC is defined.
9715 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9716 avoid calls to mallopt if zero_vector is returned.
9718 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9720 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9721 is enabled, avoid dereferencing NULL current_sblock if
9724 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9726 Cleanup basic buffer management.
9727 * buffer.h (struct buffer): Change layout to use generic vector
9728 marking code. Fix some comments. Change type of 'clip_changed'
9729 to bitfield. Remove unused #ifndef old.
9730 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9731 (GET_OVERLAYS_AT): Fix indentation.
9732 (for_each_per_buffer_object_at): New macro.

9736 * alloc.c (allocate_buffer): Adjust to match new layout of
9737 struct buffer. Fix comment.
9738 (mark_overlay): New function.

9740 Lisp area of struct buffer.
9741 (mark_object): Use it. Adjust marking of misc objects
9742 and related comments.
9744 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9746 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9747 wrapper that is not needed because the wrapped code is a no-op (zero
9748 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9749 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9751 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9753 * alloc.c (mark_buffer): Simplify. Remove prototype.
9754 (mark_object): Add comment. Reorganize marking of vector-like
9755 objects. Use CHECK_LIVE for all vector-like objects except buffers
9756 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9757 Avoid redundant calls to mark_vectorlike for bool vectors.
9759 2012-06-30 Glenn Morris <rgm@gnu.org>
9761 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9763 * epaths.in (PATH_SITELOADSEARCH): New.
9764 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9765 This is rather than relying on --enable-locallisppath elements
9766 having "site-lisp" in their names. (Bug#10208#25, 11658)
9768 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9770 * w32proc.c (sys_select): Accept and ignore one more argument.
9772 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9774 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9775 (pselect) [!MS_DOS]: Redirect to sys_select.
9777 * sysdep.c: Don't include dos.h and dosfns.h.
9779 * process.c (sys_select):
9780 * msdos.c (sys_select): Accept one more argument and ignore it.
9782 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9783 adapt data types and code to that.
9786 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9787 which clashes with the gnulib function of the same name.
9789 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9791 * font.c (font_style_to_value, font_style_symbolic)
9792 (font_prop_validate_style): Add type checks for values in
9795 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9797 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9800 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9802 * xdisp.c (try_window_id): Undo last change.
9804 * w32.c (getwd): Adjust commentary about startup_dir.
9805 (init_environment): Always call sys_access, even in non-MSVC
9806 builds. Don't chdir to the directory of the Emacs executable.
9807 This undoes code from 1997 which was justified by the need to
9808 "avoid conflicts when removing and renaming directories". But its
9809 downside was that every relative file name was being interpreted
9810 relative to the directory of the Emacs executable, which can never
9811 be TRT. In particular, it broke sys_access when called with
9812 relative file names.
9813 (sys_access): Map GetLastError to errno.
9815 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9817 * window.h (struct window): Change type of 'fringes_outside_margins'

9821 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9824 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9826 * gnutls.c (emacs_gnutls_handshake):
9827 Add QUIT to make the loop interruptible.
9829 2012-06-29 Glenn Morris <rgm@gnu.org>
9831 * charset.c (init_charset): Make lack of etc/charsets fatal.
9833 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9835 * editfns.c (region_limit): Fix type mismatch.
9837 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9839 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9840 undefined. Convert from xassert to eassert.
9841 * nsmenu.m: Convert from xassert to eassert.
9842 * nsterm.m: Likewise.
9844 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9846 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9848 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9850 Avoid integer overflow on scroll-left and scroll-right.
9851 * window.c (HSCROLL_MAX): New macro.
9852 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9853 overflow when requested scroll falls outside ptrdiff_t range.
9855 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9857 * window.h (struct window): Change type of 'hscroll',
9858 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9859 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9860 Adjust users accordingly.
9861 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9862 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9863 from EMACS_INT to ptrdiff_t.
9864 (make_window): Omit redundant initialization.
9866 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9868 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9870 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9872 * window.h (struct window): Change type of 'use_time' and
9873 'sequence_number' from Lisp_Object to int.
9874 * frame.c (make_frame): Adjust users accordingly.
9875 * print.c (print_object): Likewise.
9876 * window.c (select_window, Fwindow_use_time, make_parent_window)
9877 (make_window): Likewise.
9879 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9881 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9882 enabled with --enable-checking=[all,glyphs] configure option.
9883 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9884 adjust comments accordingly.

9935 avoid GCC warning about unused macro.
9937 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9939 * alloc.c (allocate_string): Omit intervals initialization.
9940 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9941 as in make_pure_string and make_pure_c_string.
9943 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9945 * alloc.c (allocate_string): Fix last change.
9947 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9997 * alloc.c: Remove build_string.
9998 * lisp.h: Define build_string as static inline. This provides
9999 a better opportunity to optimize away calls to strlen when the
10000 function is called with compile-time constant argument.
10001 * image.c (imagemagick_error): Convert to build_string.
10002 * w32proc.c (sys_spawnve): Likewise.

10005 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10007 Use sprintf return value instead of invoking strlen on result.
10008 In the old days this wasn't portable, since some sprintf
10009 implementations returned char *. But they died out years ago and
10010 Emacs already assumes sprintf returns int.
10011 Similarly for float_to_string.
10012 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10013 * ccl.c (ccl_driver):
10014 * character.c (string_escape_byte8):

10017 * print.c (print_object):
10018 * xdisp.c (message_dolog):
10019 * xfns.c (syms_of_xfns):
10020 Use sprintf or float_to_string result to avoid need to call strlen.
10021 * data.c (Fnumber_to_string):
10022 Use make_unibyte_string, since the string must be ASCII.
10023 * lisp.h, print.c (float_to_string): Now returns int length.
10024 * term.c (produce_glyphless_glyph):
10025 Use sprintf result rather than recomputing it.
10027 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10028 * Makefile.in (ALL_CFLAGS):
10029 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10030 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10032 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10034 * dispextern.h (xstrcasecmp): Define to library function
10035 strcasecmp if available.
10036 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10038 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10040 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10042 * menu.c (push_submenu_start, push_submenu_end)
10043 (push_left_right_boundary, push_menu_pane): Likewise.
10044 * msdos.c (dos_rawgetc): Likewise.
10046 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>

10051 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10053 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10054 sprintf already null-terminates its output.
10056 * xfns.c (x_window): Remove redundant cast.
10058 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10060 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10061 `const char *' to `char *' to avoid compiler warning.
10063 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10065 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10066 instead of truncating it to 63 (admittedly a generous limit).
10068 * process.c: Fix spelling and caps in comments.
10070 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10072 * emacs.c (setpgrp): Remove definition, unused.

10082 (SYSTIME_H): Add nt/inc/sys/time.h.
10084 * systime.h [WINDOWSNT]: Include sys/time.h.
10086 * s/ms-w32.h (struct timespec): Definition moved from
10087 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10089 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10119 Remove unnecessary forward decls.
10121 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10123 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10124 * lisp.h (WAIT_READING_MAX): New macro.
10125 * dispnew.c (Fsleep_for, sit_for):
10126 * keyboard.c (kbd_buffer_get_event):
10127 * process.c (Faccept_process_output):
10128 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10129 This improves on the previous patch, which introduced a bug
10130 when time_t is unsigned and as wide as intmax_t.
10131 See <http://bugs.gnu.org/9000#51>.
10133 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10135 * dispnew.c (sit_for, Fsleep_for):
10136 * keyboard.c (kbd_buffer_get_event):

10140 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
10142 * makefile.w32-in: Update dependencies.

10149 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10150 Privately reported by Herbert J. Skuhra.
10151 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10153 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10154 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10156 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10158 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10159 last argument of make_unibyte_string.
10161 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10162 language ID in the event parameters.
10164 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10165 event.code, not the obscure "character set ID".
10167 2012-06-23 Chong Yidong <cyd@gnu.org>
10169 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10192 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10193 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10194 Don't assume EMACS_TIME and struct timeval are the same type.
10196 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10198 Support higher-resolution time stamps (Bug#9000).
10199 The time stamps are only nanosecond-resolution at the C level,
10200 since that's the best that any real-world system supports now.
10201 But they are picosecond-resolution at the Lisp level, as that's
10202 easy, and leaves room for future OS improvements.
10204 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10207 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10208 Don't get current time unless it's needed.
10210 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10211 now provides it if it's absent.
10212 (start_atimer): Port to higher-res time stamps.
10213 Check for time stamp overflow. Don't get current time more
10214 often than is needed.
10216 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10217 Include systime.h, not time.h.
10218 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10220 * dired.c: Include stat-time.h.
10221 (Ffile-attributes): File times now have higher resolution.
10223 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10224 (struct image): Timestamp now has higher resolution.
10226 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10227 has at least microseconds now. All uses removed.
10228 (update_frame, update_single_window, update_window, update_frame_1)
10229 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10230 (duration_to_sec_usec): Remove; no longer needed.
10232 * editfns.c (time_overflow): Now extern.
10233 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10234 (float-time, Fformat_time_string, Fcurrent_time_string)

10237 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10238 (decode_time_components, lisp_seconds_argument): New functions.
10239 (make_time): Now static.
10240 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10241 Report an error if the time is invalid, rather than having the caller
10244 * fileio.c: Include <stat-time.h>
10245 (Fcopy_file): Copy higher-resolution time stamps.
10246 Prefer to set the time stamp via a file descriptor if that works.
10247 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10248 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10249 (Fvisited_file_modtime, Fset_visited_file_modtime):
10250 Support higher-resolution time stamps.
10252 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10254 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10256 * image.c (prepare_image_for_display, clear_image_cache)
10257 (lookup_image): Port to higer-resolution time stamps.
10259 * keyboard.c (start_polling, bind_polling_period):
10260 Check for time stamp overflow.
10261 (read_char, kbd_buffer_get_event, timer_start_idle)
10262 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10263 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10264 Port to higher-resolution time stamps. Do not assume time_t is signed.
10265 (decode_timer): New function. Timers are now vectors of length 9,
10266 not 8, to accommodate the picosecond component.
10267 (timer_check_2): Use it.
10269 * nsterm.m (select_timeout, timeval_subtract): Remove.
10270 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10271 as they're a bit more accurate and handle overflow better.
10272 (ns_select): Change prototype to be compatible with pselect.
10273 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10274 * nsterm.h (ns_select): Adjust prototype.
10276 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10277 us-resolution time stamps.
10278 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10280 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10282 * lisp.h (time_overflow): New decl.
10283 (wait_reading_process_output): First arg is now intmax_t, not int,
10284 to accommodate larger waits.
10286 * process.h (struct Lisp_Process.read_output_delay):
10287 Now counts nanoseconds, not microseconds.
10288 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10290 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10291 (wait_reading_process_output):
10292 Port to ns-resolution time stamps.
10293 (Faccept_process_output, wait_reading_process_output):
10294 Check for time stamp overflow. Do not assume time_t is signed.
10295 (select_wrapper): Remove; we now use pselect.
10296 (Fprocess_attributes): Now generates ns-resolution time stamps.
10298 * sysdep.c: Include utimens.h. Don't include utime.h
10299 or worry about struct utimbuf; gnulib does that for us now.
10300 (gettimeofday): Remove; gnulib provides a substitute.
10301 (make_timeval): New function.
10302 (set_file_times): Now sets ns-resolution time stamps.
10303 New arg FD; all uses changed.
10304 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10305 (system_process_attributes):
10306 Now returns ns-resolution time stamp. All uses changed.
10307 Check for time stamp overflow.
10309 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10310 provides a substitute now.
10312 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10313 since it guarantees struct timespec.
10314 (EMACS_TIME): Now struct timespec, so that we can support
10315 ns-resolution time stamps.
10316 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10317 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10318 (EMACS_USECS): Remove.
10319 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10320 so multiply the arg by 1000 before storing it.
10321 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10323 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10324 Port to ns-resolution time stamps.
10325 (EMACS_TIME_NEG_P): Remove; replaced by....
10326 (EMACS_TIME_SIGN): New macro.
10327 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10328 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10329 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10330 (make_timeval, make_lisp_time, decode_time_components): New decls.
10331 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10332 that it mishandled time_t overflow. You can't compare by subtracting!
10333 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10334 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10336 * term.c: Include <sys/time.h>.
10337 (timeval_to_Time): New function, for proper overflow wraparound.
10338 (term_mouse_position, term_mouse_click): Use it.
10340 * undo.c (record_first_change): Support higher-resolution time stamps
10341 in the undo buffer.
10342 (Fprimitive_undo): Use them when restoring time stamps.
10344 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10345 (w32_get_internal_run_time):
10346 Port to higher-resolution Emacs time stamps.
10347 (ltime): Now accepts single 64-bit integer, as that's more convenient
10350 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10352 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10353 for compatibility with pselect. Support ns-resolution time stamps.
10355 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10357 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10358 Check for time stamp overflow, and support ns-resolution time stamps.
10360 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10361 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10362 (timeval_subtract): Remove; no longer needed.
10363 (XTflash, XTring_bell, x_wait_for_event):
10364 Port to ns-resolution time stamps. Don't assume time_t is signed.
10366 2012-06-22 Chong Yidong <cyd@gnu.org>

10370 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10372 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10373 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10374 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10375 staticidx goes up to 1597 out of 1600 = 0x640.)
10377 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10379 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10380 Otherwise, the umask might be mistakenly 0 while handling input signals.
10382 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10384 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10390 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10391 access to `contents' member of Lisp_Vector objects with AREF and ASET
10394 2012-06-19 Chong Yidong <cyd@gnu.org>
10396 * frame.c (delete_frame): When selecting a frame on a different
10397 text terminal, do not alter the terminal's top-frame.
10399 * xdisp.c (format_mode_line_unwind_data): Record the target
10400 frame's selected window and its terminal's top-frame.
10401 (unwind_format_mode_line): Restore them.
10402 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10404 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10405 since tty frames can be explicitly named.
10406 (prepare_menu_bars): Likewise.
10408 * term.c (Ftty_top_frame): New function.
10410 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10412 Port byte-code-meter to modern targets.
10413 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10414 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10415 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10416 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10417 (METER_1, METER_2): Simplify.
10419 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10421 * data.c (Fdefalias): Return `symbol' (bug#11686).
10423 2012-06-18 Martin Rudalics <rudalics@gmx.at>

10852 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10853 Convert pctcpu and pctmem to Lisp float properly.
10854 Let the compiler fold better, as 100.0/0x8000 is exact.

10870 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10871 change its type from Lisp_Object to bitfield.
10872 Change type of 'force_start', 'optional_new_start',

10878 Pacify gcc -Wdouble-precision when using Xaw.
10879 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10880 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10881 Use 'float' consistently, rather than 'float' in most places
10882 and 'double' in a couple of places.
10884 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10886 * xdisp.c (handle_stop): Detect whether we have overlay strings
10887 loaded by testing it->current.overlay_string_index to be
10888 non-negative, instead of checking whether n_overlay_strings is
10889 positive. (Bug#11587)
10891 2012-05-31 Chong Yidong <cyd@gnu.org>
10893 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10895 * doc.c (Fsubstitute_command_keys): Doc fix.
10897 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10899 * search.c (search_buffer): Remove calls to
10900 r_alloc_inhibit_buffer_relocation, as it is now called by
10901 maybe_unify_char, which was the cause of relocation of buffer text
10904 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10906 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10907 for the duration of call to load_charset, to avoid problems with
10908 callers of maybe_unify_char that access buffer text through C
10911 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10912 decrement the inhibition flag, instead of just setting or
10915 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10917 Remove obsolete '#define static' cruft.
10918 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10919 This #undef was "temporary" in 2000; it is no longer needed
10920 now that '#define static' has gone away.
10921 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10922 (gray_bitmap_bits): Remove; no longer needed.
10923 All uses replaced with definiens.
10924 * xterm.c: Include "bitmaps/gray.xbm".
10926 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10928 Clean up __executable_start, monstartup when --enable-profiling.
10929 The following changes affect the code only when profiling.
10930 * dispnew.c (__executable_start): Rename from safe_bcopy.
10931 Define only on platforms that need it.
10932 * emacs.c: Include <sys/gmon.h> when profiling.
10933 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10934 (__executable_start): Remove decl, since lisp.h does it now.
10935 (safe_bcopy): Remove decl; no longer has that name.
10936 (main): Coalesce #if into single bit of code, for simplicity.
10937 Cast pointers to uintptr_t, since standard libraries want integers
10939 * lisp.h (__executable_start): New decl.
10941 2012-05-31 Glenn Morris <rgm@gnu.org>
10943 * image.c (Fimagemagick_types): Doc fix.
10945 2012-05-30 Jim Meyering <meyering@redhat.com>
10947 * callproc.c (Fcall_process_region): Include directory component
10948 in mkstemp error message (Bug#11586).
10950 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10952 * alloc.c, lisp.h (make_pure_vector): Now static.
10954 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10956 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10957 Move to byte-run.el.

10959 * data.c (Fdefalias): Purify definition, except for keymaps.
10960 (Qdefun): Move from eval.c.
10961 * lisp.h (Qdefun): Remove.
10962 * lread.c (read1): Tiny simplification.
10964 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10966 Do not create empty overlays with the evaporate property (Bug#9642).
10967 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10968 Bug#9642, but explicitly check that the buffer the overlay would
10969 be moved to is live and rearrange lines to make sure that errors
10970 will not put the overlay in an inconsistent state.
10971 (Fdelete_overlay): Cosmetics.
10973 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10975 * w32term.c (my_bring_window_to_top): New function.
10976 (x_raise_frame): Use handle returned by DeferWindowPos, which
10977 could be different from the original one.
10978 Call my_bring_window_to_top instead of my_set_foreground_window.
10981 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10982 by calling BringWindowToTop.

10987 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10989 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10990 This avoids undefined behavior that might cause the eassert
10991 to not catch an out-of-range value.
10993 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10995 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10996 Update dependencies.
10998 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11000 * bidi.c (bidi_mirror_char): Fix last change.
11002 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11004 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11005 when referring to sectname field in printf format.
11007 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11009 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11010 Only r_alloc_inhibit_buffer_relocation needed to be added;
11011 the others were already declared.
11013 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11014 before checking whether it's out of range. Put the check inside
11016 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11018 2012-05-27 Ken Brown <kbrown@cornell.edu>
11020 * callproc.c (Fcall_process): Restore a line that was accidentally
11021 commented out in the 2011-02-13 change (bug#11547).
11023 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11025 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11026 defined on ralloc.c.
11028 * buffer.c [REL_ALLOC]: Remove prototypes of
11029 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11030 they are now on lisp.h.
11032 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11034 * search.c (search_buffer): Use it to inhibit relocation of buffer
11035 text while re_search_2 is doing its job, because re_search_2 is
11036 passed C pointers to buffer text. (Bug#11519)
11038 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11039 Update value to 24.
11041 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11042 state after an additional call to move_it_in_display_line_to, keep
11043 the values of it->max_ascent and it->max_descent found for the
11045 (pos_visible_p): Revert the comparison against bottom_y to what it
11046 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11049 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11051 Fix coding-related core dumps with gcc -ftrapv.
11052 The code was computing A - B, where A and B are pointers, and B is
11053 random garbage. This can lead to core dumps on platforms that
11054 have special pointer registers, and it also leads to core dumps on
11055 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11056 A - B only when B is initialized properly.
11057 * coding.c (coding_set_source, coding_set_destination): Return void.
11058 (coding_change_source, coding_change_destinations): New functions,
11059 with the old behaviors of coding_set_source and coding_set_destination.
11060 All callers that need an offset changed to use these new functions.
11062 2012-05-26 Glenn Morris <rgm@gnu.org>
11064 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11066 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11068 Extend mouse support on W32 text-mode console.
11069 * xdisp.c (draw_row_with_mouse_face):
11070 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11072 * w32console.c: Include window.h.
11073 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11075 (initialize_w32_display): Initialize mouse-highlight data.
11077 * w32inevt.c: Include termchar.h and window.h.
11078 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11079 moves, call note_mouse_highlight. If help_echo changed, call
11080 gen_help_event to produce help-echo message in the echo area.
11081 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11084 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11086 * lread.c (read1): Simplify slightly to avoid an overflow warning
11087 with GCC 4.7.0 on x86-64.
11089 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11091 * bidi.c (bidi_mirror_char): Revert last change: an int is
11092 definitely wide enough here.
11094 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11096 Fix integer width and related bugs (Bug#9874).
11097 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11098 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11099 (string_bytes, check_sblock, allocate_string_data):
11100 (compact_small_strings, Fmake_bool_vector, make_string)
11101 (make_unibyte_string, make_multibyte_string)
11102 (make_string_from_bytes, make_specified_string)
11103 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11104 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11106 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11107 (allocate_pseudovector):
11108 Use int, not EMACS_INT, where int is wide enough.
11109 (inhibit_garbage_collection, Fgarbage_collect):
11110 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11111 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11112 int might not be wide enough.
11113 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11114 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11115 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11116 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11117 (bidi_level_of_next_char, bidi_move_to_visually_next):
11118 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11119 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11120 (Fkill_buffer, Fset_buffer_major_mode)
11121 (advance_to_char_boundary, Fbuffer_swap_text)
11122 (Fset_buffer_multibyte, overlays_at, overlays_in)
11123 (overlay_touches_p, struct sortvec, record_overlay_string)
11124 (overlay_strings, recenter_overlay_lists)
11125 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11126 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11127 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11128 (Foverlay_recenter, last_overlay_modification_hooks_used)
11129 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11130 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11131 (validate_region): Omit unnecessary test for b <= e,
11132 since that's guaranteed by the previous test.
11133 (adjust_overlays_for_delete): Avoid pos + length overflow.
11134 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11135 (report_overlay_modification):
11136 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11137 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11138 Omit pointer cast, which isn't needed anyway, and doesn't work
11139 after the EMACS_INT -> ptrdiff_t change.
11140 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11141 * buffer.h: Adjust decls to match defn changes elsewhere.
11142 (struct buffer_text, struct buffer):
11143 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11144 Use EMACS_INT, not int, where int might not be wide enough.
11145 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11146 not int, to avoid needless 32-bit limit on 64-bit hosts.
11147 (exec_byte_code): Use tighter memory-full test, one that checks
11148 for alloca overflow. Don't compute the address of the object just
11149 before an array, as that's not portable. Use EMACS_INT, not
11150 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11151 * callint.c (Fcall_interactively):
11152 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11153 * callproc.c (call_process_kill, Fcall_process):
11154 Don't assume pid_t fits into an Emacs fixnum.
11155 (call_process_cleanup, Fcall_process, child_setup):
11156 Don't assume pid_t fits into int.
11157 (call_process_cleanup, Fcall_process, delete_temp_file)
11158 (Fcall_process_region):
11159 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11160 (Fcall_process): Simplify handling of volatile integers.
11161 Use int, not EMACS_INT, where int will do.
11162 * casefiddle.c (casify_object, casify_region, operate_on_word)
11163 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11164 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11165 (casify_object): Avoid integer overflow when overallocating buffer.
11166 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11167 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11168 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11169 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11170 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11171 integers are now checked earlier. All uses replaced with XINT.
11173 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11174 For CCL_MapSingle, check that content and value are in int range.
11175 (ccl_driver, Fregister_code_conversion_map):
11176 Check that Vcode_version_map_vector is a vector.
11177 (resolve_symbol_ccl_program): Check that vector header is in range.
11178 Always copy the vector, so that we can check its contents reliably
11179 now rather than having to recheck each instruction as it's being
11180 executed. Check that vector words fit in 'int'.
11181 (ccl_get_compiled_code, Fregister_ccl_program)
11182 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11183 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11184 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11185 contents are in range.
11186 (Fccl_execute_on_string): Check that status is in range.
11187 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11188 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11189 Accept and return EMACS_INT, not int, because callers can pass values
11190 out of 'int' range.
11191 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11192 (multibyte_chars_in_text, parse_str_as_multibyte)

11194 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11195 (string_escape_byte8, Fget_byte):
11196 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11197 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11198 avoid mishandling large integers.
11199 * character.h: Adjust decls to match defn changes elsewhere.
11200 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11201 (Ffind_charset_region):
11202 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11203 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11204 (load_charset_map_from_vector, Fdefine_charset_internal):
11205 Don't assume fixnum fits in int.
11206 (load_charset_map_from_vector, Fmap_charset_chars):
11207 Remove now-unnecessary CHECK_NATNUMs.
11208 (Fdefine_charset_internal): Check ranges here, more carefully.
11209 Don't rely on undefined behavior with signed left shift overflow.
11210 Don't assume unsigned int fits into fixnum, or that fixnum fits
11211 into unsigned int. Don't require max_code to be a valid fixnum;
11212 that's not true for gb10830 4-byte on a 32-bit host. Allow
11213 invalid_code to be a cons, for the same reason. Require code_offset
11214 to be a character. Avoid int overflow if max_char is close
11216 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11217 this is intended anyway and avoids some undefined behavior.
11218 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11219 INDEX_TO_CODE_POINT, as that's what it expects.
11220 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11221 * charset.h (DECODE_CHAR): Return int, not unsigned;
11222 this is what was intended anyway, and it avoids undefined behavior.
11223 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11224 integer-overflow issues.
11225 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11226 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11227 where the argument is EMACS_INT, and this behavior is not intended.
11228 * chartab.c (Fmake_char_table, Fset_char_table_range)
11229 (uniprop_get_decoder, uniprop_get_encoder):
11230 Don't assume fixnum fits in int.
11231 * cmds.c (move_point): New function, that does the gist of
11232 Fforward_char and Fbackward_char, but does so while checking
11233 for integer overflow more accurately.
11234 (Fforward_char, Fbackward_char): Use it.
11235 (Fforward_line, Fend_of_line, internal_self_insert)
11236 (internal_self_insert):
11237 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11238 Fix a FIXME, by checking for integer overflow when calculating
11239 target_clm and actual_clm.
11240 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

11261 (Fdefine_coding_system_internal)
11262 (coding_set_source, coding_set_destination):

11264 (setup_iso_safe_charsets, consume_chars, Funencodable_char_position)
11265 (Fdefine_coding_system_internal):
11266 Don't assume fixnums fit in int.

11269 (Funencodable_char_position, Fcheck_coding_systems_region)
11270 (get_translation, handle_composition_annotation, consume_chars):
11271 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

11952 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11954 Assume C89 or later.
11955 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11956 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11958 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
11959 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11960 * textprop.c, tparam.c (NULL): Remove.
11961 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11962 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11963 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11964 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11965 * xterm.c (input_signal_count): Assume volatile works.
11967 2012-05-21 Ken Brown <kbrown@cornell.edu>
11969 * xgselect.c (xg_select): Fix first argument in call to 'select'
11972 2012-05-20 Ken Brown <kbrown@cornell.edu>
11974 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11975 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11977 2012-05-19 Ken Brown <kbrown@cornell.edu>
11979 * xfns.c (x_in_use): Remove `static' qualifier.
11980 * xterm.h (x_in_use): Declare.
11981 * xgselect.c: Include xterm.h.
11982 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11983 and `display_arg' (bug#9754).
11985 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11987 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11989 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11990 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11992 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11994 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11996 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11997 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11999 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12000 reference to image_cache->refcount.
12001 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12003 2012-05-17 Juri Linkov <juri@jurta.org>
12005 * search.c (Fword_search_regexp, Fword_search_backward)
12006 (Fword_search_forward, Fword_search_backward_lax)
12007 (Fword_search_forward_lax): Move functions to isearch.el
12008 (bug#10145, bug#11381).
12010 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12012 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12014 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12016 * lread.c (init_obarray): Declare Qt and Qnil as special.
12018 2012-05-14 Glenn Morris <rgm@gnu.org>
12020 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12021 Put "libexec" before "bin", for the sake of init_callproc_1.
12023 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12025 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12027 * unexaix.c: Port to more-recent AIX compilers.
12028 (report_error, report_error_1, make_hdr, copy_sym)
12029 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12030 Make arguments const char *, not char *, to avoid violations of C
12031 standard and to fix some AIX warnings reported by Gilles Pion.
12033 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12035 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12036 already have overlays loaded.
12037 (handle_single_display_spec): Before returning without displaying
12038 fringe bitmap, synchronize the bidi iterator with the main display
12039 iterator, by calling iterate_out_of_display_property.
12040 (iterate_out_of_display_property): Detect buffer iteration by
12041 testing that it->string is a Lisp string.
12042 (get_next_display_element): When the current object is exhausted,
12043 and there's something on it->stack, call set_iterator_to_next to
12044 proceed with what's on the stack, instead of returning zero.
12045 (set_iterator_to_next): If called at the end of a Lisp string,
12046 proceed to consider_string_end without incrementing string
12047 position. Don't increment display vector index past the end of
12048 the display vector. (Bug#11417)
12049 (pos_visible_p): Don't report a position visible when move_it_to
12050 stopped at the last line of window, which happens to be scanned
12051 backwards by the bidi iteration. (Bug#11464)
12053 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12055 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12056 and right-margin display specs even if the spec is invalid or we
12057 are on a TTY, and thus unable to display on the fringes.
12058 That's because the text with the property will not be displayed anyway,
12059 so we need to signal to the caller that this is a "replacing"
12060 display spec. This fixes display when the spec is invalid or we
12063 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12065 * unexaix.c (make_hdr): Fix typo in prototype.
12066 This bug broke the build on AIX. Problem reported by Gilles Pion.
12068 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12070 * keyboard.c (kbd_buffer_get_event): Read special events also in
12071 batch mode. (Bug#11415)
12073 2012-05-12 Glenn Morris <rgm@gnu.org>
12075 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12077 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12079 * lisp.mk (lisp): Add newcomment.elc.
12081 2012-05-12 Glenn Morris <rgm@gnu.org>
12083 * Makefile.in (MKDIR_P): New, set by configure.
12084 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12086 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12088 Remove unused function hourglass_started.
12089 * dispextern.h (hourglass_started):
12090 * w32fns.c (hourglass_started):
12091 * xdisp.c (hourglass_started): Remove.
12093 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12095 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12096 Update dependencies.
12098 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12100 * xgselect.c (xg_select): Put maxfds+1 into a var.
12101 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12103 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12105 2012-05-10 Dave Abrahams <dave@boostpro.com>
12107 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12108 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12110 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12112 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12113 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12114 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12115 Initialize xd_registered_buses.
12117 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12119 Untag more efficiently if USE_LSB_TAG.
12120 This is based on a proposal by YAMAMOTO Mitsuharu in
12121 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12122 For an admittedly artificial (nth 8000 longlist) benchmark on
12123 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12124 Emacs's overall text size by 1%.
12125 * lisp.h (XUNTAG): New macro.
12126 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12127 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12128 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12129 * eval.c (Fautoload):
12130 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12131 * frame.h (XFRAME): Use XUNTAG.
12133 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12134 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12135 Remove unportable assumptions about print widths of types like
12137 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12138 intptr_t when converting between pointer and integer, to avoid GCC
12139 warnings about wrong width.
12141 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12143 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12144 stack for each reader_thread, instead of defaulting to 8MB
12145 determined by the linker. This avoids failures in creating
12146 subprocesses on Windows 7, see the discussion in this thread:
12147 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12149 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12151 Fix up display of the *Minibuf-0* buffer in the mini window.
12152 * keyboard.c (read_char): Don't clear the echo area if there's no
12154 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12155 contents of *Minibuf-0*) if there's no message displayed in its stead.
12157 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12159 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12162 2012-05-06 Chong Yidong <cyd@gnu.org>
12164 * lisp.mk (lisp): Update.
12166 2012-05-05 Jim Meyering <meyering@redhat.com>
12168 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12170 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12172 * data.c (PUT_ERROR): New macro.
12173 (syms_of_data): Use it. Add new error type `user-error'.
12174 * undo.c (user_error): New function.
12175 (Fprimitive_undo): Use it.
12176 * print.c (print_error_message): Adjust print style for `user-error'.
12177 * keyboard.c (user_error): New function.
12178 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12180 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12182 Do not limit current-time-string to years 1000..9999.
12183 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12184 (Fcurrent_time_string): Support any year that is supported by the
12185 underlying localtime representation. Don't use asctime, as it
12186 has undefined behavior for years outside the range -999..9999.
12188 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12190 Fix race conditions involving setenv, gmtime, localtime, asctime.
12191 Without this fix, interrupts could mess up code that uses these
12192 nonreentrant functions, since setting TZ invalidates existing
12193 tm_zone or tzname values, and since most of these functions return
12194 pointers to static storage.
12195 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12196 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12197 Grow the critical sections to include not just invoking
12198 localtime/gmtime, but also accessing these functions' results
12199 including their tm_zone values if any, and any related TZ setting.
12200 (format_time_string): Last arg is now struct tm *, not struct tm **,
12201 so that the struct tm is saved in the critical section.
12202 All callers changed. Simplify allocation of initial buffer, partly
12203 motivated by the fact that memory allocation needs to be outside
12204 the critical section.
12206 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12208 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12209 with RESET_INTERVAL.
12211 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12212 Remove duplicated buffer name initialization.
12214 2012-05-02 Jim Meyering <jim@meyering.net>
12216 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12218 * xfns.c (x_window): Use xstrdup (Bug#11375).
12220 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12222 * xdisp.c (pos_visible_p): If already at a newline from the
12223 display string before the 'while' loop, don't walk back the glyphs
12224 from it3.glyph_row. Solves assertion violation when the display
12225 string begins with a newline (egg.el). (Bug#11367)
12227 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12229 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12232 2012-05-01 Glenn Morris <rgm@gnu.org>
12234 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12235 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12236 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12237 All were removed before 23.1.
12239 * dispnew.c: Remove HAVE_LIBNCURSES test;
12240 it is always true on relevant platforms.
12242 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12243 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12245 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12247 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12249 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12250 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12253 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12255 Do not avoid creating empty evaporating overlays (Bug#9642).
12256 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12257 That is, do not delete an evaporating overlay if it becomes
12258 empty after its bounds are adjusted to fit within its buffer.
12259 This fix caused other problems, and I'm reverting it until we get
12260 to the bottom of them.
12262 2012-04-27 Chong Yidong <cyd@gnu.org>
12264 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12266 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12268 * xdisp.c (pos_visible_p): If the window start position is beyond
12269 ZV, start the display from buffer beginning. Prevents assertion
12270 violation in init_iterator when the minibuffer window is scrolled
12271 via the scroll bar.
12273 * window.c (window_scroll_pixel_based): Likewise.
12275 2012-04-27 Chong Yidong <cyd@gnu.org>
12277 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12279 2012-04-27 Glenn Morris <rgm@gnu.org>
12281 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12282 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12284 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12286 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12287 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12289 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12291 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12292 display element, check also the underlying string or buffer
12293 character. (Bug#11341)
12295 * w32menu.c: Include w32heap.h.
12296 (add_menu_item): If the call to AppendMenuW (via
12297 unicode_append_menu) fails, disable Unicode menus only if we are
12298 running on Windows 9X/Me.
12300 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12302 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12303 (xgetint): Add missing shift for LSB tags.
12305 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12307 * keyboard.c (read_char): Don't wipe echo area for select window
12308 events: These might get delayed via `mouse-autoselect-window'
12311 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12313 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12314 manipulation of :loaded-from data.
12316 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12318 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12319 now a cons (bug#11311).
12321 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12323 Do not create empty overlays with the evaporate property (Bug#9642).
12324 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12325 if it becomes empty after its bounds are adjusted to fit within
12326 its buffer. Without this fix, in a nonempty buffer (let ((o
12327 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12328 yields an empty overlay that has the evaporate property, which is
12329 not supposed to happen.
12331 Fix minor GTK3 problems found by static checking.
12332 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12333 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12334 (struct _EmacsFixedClass, emacs_fixed_get_type):
12335 Move decls here from emacsgtkfixed.h, since they needn't be public.
12336 (emacs_fixed_get_type): Now static.
12337 (emacs_fixed_class_init): Omit unused local.
12338 (emacs_fixed_child_type): Remove; unused.
12339 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12340 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12341 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12342 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12343 (EMACS_FIXED_GET_CLASS): Remove; unused.
12344 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12346 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12347 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12349 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12351 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12352 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12353 (__malloc_size_t, __malloc_ptrdiff_t):
12354 Remove. All uses removed, replaced by the definiens if needed,
12355 since we can assume C89 or better now.
12356 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12364 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12365 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12366 Define using prototypes, not old style.
12367 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
12368 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
12369 (align): Don't assume that signed integer overflow wraps around.
12370 Omit unused local var.
12371 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
12372 (_free_internal_nolock, memalign, mallochook, reallochook):
12373 Omit no-longer-needed casts.
12374 (valloc): Use getpagesize, not __getpagesize.
12375 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
12376 (struct hdr): The 'magic' member is now size_t, not unsigned long.
12378 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
12380 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
12382 Move functions from C to Lisp. Make non-blocking method calls
12383 the default. Implement further D-Bus standard interfaces.
12385 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

12444 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12446 * sysdep.c [__FreeBSD__]: Minor cleanups.
12447 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12448 Use Emacs indenting style more consistently. Avoid some casts.

12467 * print.c (print_preprocess): Only check print_depth if print-circle
12469 (print_object): Check for cycles even when print-circle is nil and

12474 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12475 set the status to "failed" and ensure that sentinel is run.
12477 2012-04-20 Glenn Morris <rgm@gnu.org>
12479 * process.c (Fset_process_inherit_coding_system_flag)
12480 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12532 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12533 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12534 (NEED_MEM_INSERT): New macro.
12535 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12536 Remove one incorrect comment and fix another.

12572 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12573 * s/netbsd.h, s/sol2-6.h:
12574 Remove definition of GC_MARK_STACK, since the default now works.
12575 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12603 2012-04-11 Daniel Colascione <dancol@dancol.org>
12605 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12606 against is gone. It's better to use vfork now so that when Cygwin
12607 gains a new, working vfork, we use it automatically (bug#10398).
12609 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12630 being loaded (bug#10424).
12632 2012-04-09 Glenn Morris <rgm@gnu.org>
12634 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

12662 * minibuf.c (Fread_variable): Callers changed.
12664 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12666 * xdisp.c (set_cursor_from_row): If the display string appears in
12667 the buffer at position that is closer to point than the position
12668 after the display string, display the cursor on the first glyph of
12669 the display string. Fixes cursor display when a 'display' text
12670 property immediately follows invisible text. (Bug#11094)
12672 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12674 composite.c: use 'double' consistently
12675 * composite.c (get_composition_id): Use 'double' consistently
12676 instead of converting 'float' to 'double' and vice versa; this is
12677 easier to understand and avoids a GCC warning.
12679 2012-04-09 Glenn Morris <rgm@gnu.org>
12681 * Makefile.in: Generate leim-list with bootstrap-emacs, in

12726 [!WINDOWSNT]: New macros.
12727 (init_libxml2_functions, libxml2_loaded_p): New functions.

12731 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12733 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12734 Call init_libxml2_functions before calling libxml2 functions.

12745 * indent.c (Fvertical_motion): If there is a display string at
12746 point, use it.vpos to compute how many lines to backtrack after
12747 move_it_to point. (Bug#11133)
12749 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12751 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12752 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12753 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12754 macros related to unification of CJK characters. For the details,
12755 see the discussion following the message here:
12756 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

12772 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12774 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12775 position we get to after a call to move_it_to fails the
12776 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12777 only if we wind up in a string from display property. (Bug#11063)
12779 * window.c (Fdelete_other_windows_internal): Invalidate the row
12780 and column information about mouse highlight, so that redisplay
12781 restores it after reallocating the glyph matrices. (Bug#7464)
12783 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12784 string comes from a `display' text property, use the buffer
12785 position of that property as if we actually saw that position in
12787 (move_it_by_lines): Remove the assertion that
12788 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12789 violated when there's a before-string at the beginning of a line.

12798 (display_line): Call extend_face_to_end_of_line when the default
12799 face was remapped. (Bug#11068)

12836 * s/ms-w32.h (tzname): Include time.h before redirecting to

12839 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12841 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12844 * xterm.c (XTread_socket): Only modify handling_signal if
12845 !SYNC_INPUT. (Bug#11080)
12847 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12849 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12850 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12851 when fetching a multibyte character consumes more bytes than
12852 CHAR_BYTES returns, due to unification of CJK characters in
12853 string_char. (Bug#11073)
12855 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12857 * process.c (wait_reading_process_output): Handle pty disconnect
12858 by refraining from sending oneself a SIGCHLD (bug#10933).

12864 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12865 Mark string as coming from a prefix property.
12866 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12867 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12869 2012-03-21 Chong Yidong <cyd@gnu.org>
12871 * xfaces.c (Vface_remapping_alist): Doc fix.
12873 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12875 * w32proc.c (Fw32_set_console_codepage)
12876 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12879 2012-03-20 Chong Yidong <cyd@gnu.org>
12881 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12882 to reflect default non-nil value of redisplay-dont-pause.
12884 2012-03-19 Kenichi Handa <handa@m17n.org>
12886 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12887 it fit in a valid range (Bug#11003).
12889 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12891 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12892 that is not from display property, accept the row as a "cursor
12893 row" if one of the string's character has a non-nil `cursor'
12894 property. Fixes cursor positioning when there are newlines in
12895 overlay strings, e.g. in icomplete.el. (Bug#11035)
12897 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12899 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12901 2012-03-12 Chong Yidong <cyd@gnu.org>
12903 * eval.c (inhibit_lisp_code): Rename from
12904 inhibit_window_configuration_change_hook; move from window.c.
12906 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12907 * window.c (run_window_configuration_change_hook)
12908 (syms_of_window): Callers changed.

12914 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12916 2012-03-10 Chong Yidong <cyd@gnu.org>
12918 * frame.c (other_visible_frames): Don't assume the selected frame
12919 is visible (Bug#10955).
12921 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12923 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12927 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12928 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12931 2012-03-03 Glenn Morris <rgm@gnu.org>
12933 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12935 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12937 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12938 position past the first glyph_row that ends at ZV. (Bug#10902)
12939 (redisplay_window, next_element_from_string): Fix typos in
12941 (redisplay_window): Pass to move_it_vertically the margin in
12942 pixels, not in screen lines.
12944 2012-03-02 Glenn Morris <rgm@gnu.org>
12946 * buffer.c (buffer-list-update-hook): Doc fix.
12948 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12950 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12951 push_it before setting up the iterator for the first overlay
12952 string, even if we have an empty string loaded.
12953 (next_overlay_string): If there's an empty string on the iterator
12954 stack, pop the stack. (Bug#10903)
12956 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12958 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12959 Suggested by Stefan Monnier in
12960 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12961 * alloc.c (widen_to_Lisp_Object): New static function.
12962 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12963 and widening them to Lisp_Objects. This would work even if
12964 USE_LSB_TAG is defined and wide integers are used, which might
12965 happen in a future version of Emacs.
12967 2012-02-25 Chong Yidong <cyd@gnu.org>
12969 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12972 * xselect.c (Fx_selection_exists_p): Doc fix.
12973 (x_clipboard_manager_save_all): Print an informative message
12974 before saving to clipboard manager.
12976 2012-02-24 Chong Yidong <cyd@gnu.org>
12978 * keyboard.c (process_special_events): Handle all X selection
12979 requests in kbd_buffer, not just the next one (Bug#8869).
12981 2012-02-23 Chong Yidong <cyd@gnu.org>
12983 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12984 call when setting menu-bar-lines and tool-bar-lines parameters.
12985 (unwind_create_frame_1): New helper function.
12987 * window.c (inhibit_window_configuration_change_hook): New var.
12988 (run_window_configuration_change_hook): Obey it.
12989 (syms_of_window): Initialize it.
12991 2012-02-22 Chong Yidong <cyd@gnu.org>
12993 * xterm.c (x_draw_image_relief): Add missing type check for
12994 Vtool_bar_button_margin (Bug#10743).
12996 2012-02-21 Chong Yidong <cyd@gnu.org>
12998 * fileio.c (Vfile_name_handler_alist): Doc fix.
13000 * buffer.c (Fget_file_buffer): Protect against invalid file
13001 handler return value.
13003 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13005 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13006 when computing $valmask.
13008 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13009 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13010 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13011 It's useless in that case, and it can cause problems on hosts
13012 that allocate halves of EMACS_INT values separately.
13013 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13014 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13015 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13016 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13017 it avoids undefined behavior on hosts where shifting right by more
13018 than the word width has undefined behavior.
13020 2012-02-19 Chong Yidong <cyd@gnu.org>
13022 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13023 (Funhandled_file_name_directory, Ffile_name_as_directory)
13024 (Fdirectory_file_name, Fexpand_file_name)
13025 (Fsubstitute_in_file_name): Protect against invalid file handler
13026 return values (Bug#10845).
13028 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13030 * .gdbinit (pitx): Fix incorrect references to fields of the

13040 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13042 2012-02-15 Chong Yidong <cyd@gnu.org>
13044 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13045 marked as special. Also, starting docstrings with * is obsolete.
13047 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13049 * gnutls.c (emacs_gnutls_write): Fix last change.

13058 * keymap.c (Fsingle_key_description): Handle char ranges.
13060 2012-02-12 Chong Yidong <cyd@gnu.org>
13062 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13063 as that creates a dangerous corner case.
13065 * window.c (Fdelete_window_internal): Invalidate the mouse
13066 highlight (Bug#9904).
13068 2012-02-12 Glenn Morris <rgm@gnu.org>

13071 (Fx_get_selection_internal, Fx_disown_selection_internal)
13072 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13073 * nsselect.m (Fx_own_selection_internal)
13074 (Fx_disown_selection_internal, Fx_selection_exists_p)
13075 (Fx_selection_owner_p, Fx_get_selection_internal):
13076 Sync docs and argument specs with the xselect.c versions.
13078 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13080 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13082 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13084 * w32select.c (Fx_selection_exists_p): Sync doc string and
13085 argument list with xselect.c. (Bug#10783)

13098 2012-02-07 Chong Yidong <cyd@gnu.org>
13100 * buffer.c (Fbuffer_local_variables)
13101 (buffer_lisp_local_variables): Handle unbound vars correctly;
13102 don't let Qunbound leak into Lisp.
13104 2012-02-07 Glenn Morris <rgm@gnu.org>
13106 * image.c (Fimagemagick_types): Doc fix.
13108 * image.c (imagemagick-render-type): Change it from a lisp object
13109 to an integer. Move the doc here from the lisp manual.
13110 Treat all values not equal to 0 the same.

13122 2012-02-04 Chong Yidong <cyd@gnu.org>
13124 * nsterm.m: Declare a global (Bug#10694).
13126 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13128 * w32.c (get_emacs_configuration_options):
13129 Include --enable-checking, if specified, in the return value.
13131 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13133 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13134 after rounding frame sizes. (Bug#9723)

13138 * keyboard.c (adjust_point_for_property): Don't position point
13139 before BEGV. (Bug#10696)
13141 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13143 Handle overflow when computing char display width (Bug#9496).
13144 * character.c (char_width): Return EMACS_INT, not int.
13145 (char_width, c_string_width): Check for overflow when
13146 computing the width; this is possible now that individual
13147 characters can have unbounded width. Problem introduced
13148 by merge from Emacs 23 on 2012-01-19.
13150 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13152 * dbusbind.c (Fdbus_register_method): Mention the return value
13153 :ignore in the docstring.

13165 2012-02-02 Kenichi Handa <handa@m17n.org>
13167 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13168 0, do not call append_composite_glyph.
13170 2012-02-02 Kenichi Handa <handa@m17n.org>
13172 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13174 (x_produce_glyphs): If the component of a composition is a null
13175 string, set it->pixel_width to 1 to avoid zero-width glyph.
13177 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13179 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13180 first 2 arguments are identical. This makes inserting large
13181 output from a subprocess an order of magnitude faster on
13182 MS-Windows, where all sbrk'ed memory is always contiguous.
13184 2012-01-31 Glenn Morris <rgm@gnu.org>
13186 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13222 2012-01-21 Chong Yidong <cyd@gnu.org>
13224 * floatfns.c (Fcopysign): Make the second argument non-optional,
13225 since nil is not allowed anyway.
13227 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13229 * process.c (read_process_output): Use p instead of XPROCESS (proc).

13236 Rewrite doc-strings.
13238 2012-01-19 Kenichi Handa <handa@m17n.org>
13240 * character.c (char_width): New function.
13241 (Fchar_width, c_string_width, lisp_string_width):
13242 Use char_width (Bug#9496).

13264 he end column for display of highlight that ends on a newline
13267 2012-01-11 Glenn Morris <rgm@gnu.org>
13269 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
13270 from load-path also when installation-directory is nil. (Bug#10208)
13272 2012-01-10 Glenn Morris <rgm@gnu.org>
13274 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
13276 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
13277 Update template values to be closer to their typical values these days.
13279 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13281 * xdisp.c (rows_from_pos_range): Accept additional argument
13282 DISP_STRING, and accept any glyph in a row whose object is that
13283 string as eligible for mouse highlight. Fixes mouse highlight of
13284 display strings from overlays. (Bug#10464)
13286 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
13288 emacs: fix an auto-save permissions race condition (Bug#10400)
13289 * fileio.c (auto_saving_dir_umask): New static var.
13290 (Fmake_directory_internal): Use it.
13291 (do_auto_save_make_dir): Set it, instead of invoking chmod after
13292 creating the directory. The old code temporarily assigns
13293 too-generous permissions to the directory.
13294 (do_auto_save_eh): Clear it.
13295 (Fdo_auto_save): Catch all errors, not just file errors, so
13296 that the var is always cleared.
13298 2012-01-07 Eli Zaretskii <eliz@gnu.org>
13300 * search.c (scan_buffer): Pass character positions to
13301 know_region_cache, not byte positions. (Bug#6540)

13801 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13802 is set, removing the need for VIRT_ADDRESS_VARIES.
13803 (PURE_P): Use a more-efficient implementation that needs just one
13804 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13805 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13806 to 4 (xorl, subq, cmpq, setbe).
13807 * alloc.c (pure): Always extern now, since that's the
13808 VIRT_ADDR_VARIES behavior.
13809 (PURE_POINTER_P): Use a single comparison, not two, for
13810 consistency with the new puresize.h.
13811 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13812 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13813 Remove VIRT_ADDR_VARIES no longer needed.
13815 2011-11-19 Eli Zaretskii <eliz@gnu.org>
13817 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
13818 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13819 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13820 behave as if the cursor position were at the window margin.
13822 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13823 and the cursor position is out of bounds, behave as if the cursor
13824 position were at the window margin. (Bug#10075)
13826 2011-11-18 Chong Yidong <cyd@gnu.org>
13828 * window.c (Fwindow_combination_limit): Make first argument

13846 hash values of the two rows. (Bug#10035)
13847 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13849 * xdisp.c (row_hash): New function, body extracted from
13850 compute_line_metrics.
13851 (compute_line_metrics): Call row_hash, instead of computing the
13854 * dispnew.c (verify_row_hash): Call row_hash for computing the
13855 hash code of a row, instead of duplicating code from xdisp.c.
13857 * dispextern.h (row_hash): Add prototype.
13859 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13861 * frame.c (delete_frame): Don't delete the terminal when the last

13886 (recombine_windows, make_parent_window, make_window)
13887 (Fsplit_window_internal, saved_window)
13888 (Fset_window_configuration, save_window_save): Rename all
13889 occurrences of window_nest to window_combination_limit.
13891 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
13893 * image.c (imagemagick_load_image): Fix typo.
13895 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13897 * xdisp.c (display_line): Move the call to
13898 highlight_trailing_whitespace before the call to
13899 compute_line_metrics, since the latter needs to see the final
13900 faces of all the glyphs to compute ROW's hash value.
13901 Fixes assertion violations in row_equal_p. (Bug#10035)
13903 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13905 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13906 just return (bug#10044).
13908 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13910 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13911 with user-defined heap size. Bump the default size of the temacs
13912 heap to 27MB, to avoid memory warning when running temacs.
13913 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13915 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13916 current_matrix and desired_matrix. (Bug#9990)
13917 (verify_row_hash) [XASSERTS]: New function.
13918 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13919 that the hash value of glyph rows is correct.

13948 2011-11-11 Johan Bockgård <bojohan@gnu.org>
13950 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
13951 avoid a crash (bug#9496).
13953 2011-11-09 Chong Yidong <cyd@gnu.org>
13955 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13962 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13964 Avoid some portability problems by eschewing 'extern inline' functions.
13965 The trivial performance wins aren't worth the portability hassles; see
13966 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13968 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13969 (window_box_width, window_box_left, window_box_left_offset)
13970 (window_box_right, window_box_right_offset): Undo previous change,
13971 by removing the "extern"s.
13972 * intervals.c (adjust_intervals_for_insertion)
13973 (adjust_intervals_for_deletion): Undo previous change,
13974 making these static again.
13975 (offset_intervals, temp_set_point_both, temp_set_point)
13976 (copy_intervals_to_string): No longer inline.
13977 * xdisp.c (window_text_bottom_y, window_box_width)
13978 (window_box_height, window_box_left_offset)
13979 (window_box_right_offset, window_box_left, window_box_right)

14001 2011-11-07 Martin Rudalics <rudalics@gmx.at>
14003 * window.h: Declare delete_all_child_windows instead of
14004 delete_all_subwindows.
14005 * window.c (Fwindow_nest, Fset_window_nest)
14006 (Fset_window_new_total, Fset_window_new_normal)
14007 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
14008 (delete_all_subwindows): Rename to delete_all_child_windows.
14009 (Fdelete_other_windows_internal, Fset_window_configuration):
14010 Call delete_all_child_windows instead of delete_all_subwindows.

14014 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
14016 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14017 This is also needed for porting to any host where GC_MARK_STACK is
14018 not GC_MAKE_GCPROS_NOOPS.
14019 (which_symbols): Use it.
14021 2011-11-07 Kenichi Handa <handa@m17n.org>

14034 * xmenu.c (cleanup_widget_value_tree): New function.
14035 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14036 calling free_menubar_widget_value_tree directly (Bug#9830).

14040 Fix some portability problems with 'inline'.
14041 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14042 (window_box_width, window_box_left, window_box_left_offset)
14043 (window_box_right, window_box_right_offset): Declare extern.
14044 Otherwise, these inline functions do not conform to C99 and
14045 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14046 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14047 * intervals.c (adjust_intervals_for_insertion)
14048 (adjust_intervals_for_deletion): Now extern, because otherwise the
14049 extern inline functions 'offset_intervals' couldn't refer to it.
14050 (static_offset_intervals): Remove.
14051 (offset_intervals): Rewrite using the old contents of
14052 static_offset_intervals. The old version didn't conform to C99
14053 because an extern inline function contained a reference to an
14054 identifier with static linkage.
14056 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14058 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14063 * xdisp.c (init_iterator, reseat_to_string): Don't set the
14064 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
14065 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
14066 return Qleft_to_right.

14071 (Fminibuffer_window, Fwindow_buffer, Fwindow_splits)
14072 (Fset_window_splits, Fwindow_nest, Fset_window_nest)
14073 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
14074 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
14075 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
14076 (Fwindow_vscroll): Doc fix.
14077 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14078 argument, since it makes no sense to pass a live window and for
14079 consistency with window-child.

14104 2011-11-05 Jan Djärv <jan.h.d@swipnet.se>
14106 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
14107 (unwind_create_frame): New function (Bug#9943).
14108 (Fx_create_frame): Restructure code to be more similar to the one in
14109 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
14110 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
14111 Move terminal->reference_count++ just before making the frame official
14114 * nsterm.m (x_free_frame_resources): New function.
14115 (x_destroy_window): Move code to x_free_frame_resources.
14117 * xfns.c (unwind_create_frame): Fix comment.
14118 (Fx_create_frame, x_create_tip_frame):
14119 Move terminal->reference_count++ just before making the frame
14120 official. Move initialization of image_cache_refcount and
14121 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

14251 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14252 Not clear what it was for, and it causes various bugs. (Bug#9839)
14254 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14256 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14257 possible random value that matches one of those tested as
14258 condition to clear the mouse face.
14260 2011-10-28 Chong Yidong <cyd@gnu.org>
14262 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14264 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14266 * window.c (make_window): Initialize phys_cursor_on_p.
14268 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14270 * lisp.h (struct Lisp_Symbol): Update comments.
14272 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14274 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14276 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14278 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14279 <oslsachem@gmail.com> for helping to debug this.
14281 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14282 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14283 (g_b_init_get_glyph_outline_w): New static variables.
14284 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14285 (GetGlyphOutlineW_Proc): New typedefs.
14286 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14287 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14289 (w32font_open_internal, compute_metrics):
14290 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14291 instead of calling the "wide" APIs directly.
14293 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14295 * w32.h (syms_of_w32font): Add prototype.
14297 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14299 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14300 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14301 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14302 (Fmove_to_window_line): Doc fix.
14304 2011-10-27 Chong Yidong <cyd@gnu.org>
14306 * process.c (make_process): Set gnutls_state to NULL.
14308 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14309 non-NULL, regardless of GNUTLS_INITSTAGE.
14310 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14311 an error. Set process slots as soon as we allocate them.
14313 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14315 2011-10-27 Chong Yidong <cyd@gnu.org>
14317 * gnutls.c (emacs_gnutls_deinit): New function.
14318 Deallocate credentials structures as well as calling gnutls_deinit.
14319 (Fgnutls_deinit, Fgnutls_boot): Use it.
14321 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14322 (deactivate_process): Call emacs_gnutls_deinit.
14324 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14326 * image.c (x_create_x_image_and_pixmap):
14327 * w32.c (sys_rename, w32_delayed_load):
14328 * w32font.c (fill_in_logfont):
14329 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14331 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14333 * w32fns.c (w32_default_color_map): New function,
14334 extracted from Fw32_default_color_map.
14335 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14337 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14339 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14341 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14343 * keyboard.c (test_undefined): New function (bug#9751).
14344 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14346 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14348 * sysdep.c (init_sys_modes): Fix the check for the controlling
14349 terminal (Bug#6649).
14351 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14353 * dispextern.h (struct bidi_it): New member next_en_type.
14355 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14356 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14357 current character, check also for next_en_type being WEAK_EN.
14358 (bidi_resolve_weak): Don't enter the expensive loop if the current
14359 position is before next_en_pos. Record the bidi type of the first
14360 non-ET, non-BN character we find, in addition to its position.
14361 (bidi_level_of_next_char): Invalidate next_en_type when
14362 next_en_pos is over-stepped.
14364 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14366 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14367 * editfns.c: Rewrite current-time-zone so that it invokes
14368 the equivalent of (format-time-string "%Z") to get the time zone name.
14369 This fixes a bug when the time zone name contains characters that
14370 need converting from the system time locale to Emacs internal format.
14371 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14372 that patch fixed format-time-string to do the conversion, but
14373 I forgot to fix current-time-zone.
14374 (format_time_string): New function, containing most of
14375 what Fformat_time_string used to contain.
14376 (Fformat_time_string): Rewrite in terms of format_time_string.
14377 This doesn't change this function's behavior.
14378 (current-time-zone): Rewrite to use format_time_string.
14379 This fixes the bug reported by Michael Schierl in
14380 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14381 Jason Rumney's 2007-06-07 change worked around this bug, but
14383 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14385 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14387 * xdisp.c (start_display): If the character at POS is displayed
14388 via a display vector, reset IT->current.dpvec_index to zero.
14389 (try_window_reusing_current_matrix): If a line ends in a display
14390 vector or the next line starts in a display vector, continue
14391 redrawing the window even though the character position of
14392 start_row was reached.
14395 2011-10-18 Chong Yidong <cyd@gnu.org>
14397 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14398 with nobreak-char-display too.
14400 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14402 Fix part 3 of bug#9771.
14403 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14404 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14405 non-neutral characters if the current character is a paragraph
14406 separator (a.k.a. Newline). This avoids running the same
14407 expensive loop twice, once when we consume the preceding newline
14408 and the other time when the line actually needs to be displayed.
14409 Avoid the loop when we see neutrals on the base embedding level
14410 following a character whose directionality is the same as the
14411 paragraph's. This avoids running the expensive loop when a line
14412 ends in a long sequence of neutrals, like control characters.
14413 Add assertion against STRONG_AL type. Slightly rearrange code
14414 that determines the type of a neutral given the first non-neutral
14416 (bidi_level_of_next_char): Set next_en_pos to zero when
14417 invalidating its info.
14419 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14421 * xdisp.c (push_display_prop): Determine whether to record string
14422 or buffer position by IT->string, not by IT->method. Allow
14423 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14424 (move_it_vertically_backward): Don't look for character position
14425 immediately after the newline when in a continuation line.
14428 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14430 * window.c (coordinates_in_window): Rewrite and delabelize
14431 vertical border check. (Bug#5357) (Bug#9618)
14433 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14435 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14436 errors in XSetWindowBorder (bug#9310).
14438 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14440 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14441 avoid crash when xmalloc overrun checking is enabled.
14443 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14445 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14446 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14447 cursor motion with <left> and <right> arrow keys.
14449 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14450 some callers set that themselves.
14452 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14454 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14455 display string and the previous row comes from the same string and
14456 is empty. (Bug#9739) (Bug#9738)
14458 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14460 * doc.c (get_doc_string): Encode file name (bug#9735).
14462 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14464 * bidi.c (bidi_level_of_next_char):
14465 * xdisp.c (get_visually_first_element): Remove old incorrect
14466 comments regarding the Unicode Line Separator character.
14468 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14470 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14472 * alloc.c (Fgc_status): Do not access beyond zombies array
14473 boundary if nzombies > MAX_ZOMBIES.
14474 * alloc.c (dump_zombies): Add missing format specifier.
14476 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14478 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14479 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14481 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14482 Some packages use them to denote characters with modifiers.
14484 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14486 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14487 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14488 matching a pp-number. Rename parameter var to var1.
14490 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14492 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14494 2011-10-08 Glenn Morris <rgm@gnu.org>
14496 * callint.c (Fcall_interactively): Give a more explicit error for the
14497 'c' case with a non-character input. (Bug#8479)
14499 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14501 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14503 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14504 lines that are hscrolled on the left.
14506 * dispnew.c (buffer_posn_from_coords): Account for a possible
14507 presence of header-line. (Bug#4426)
14509 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14511 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14512 Don't advertise functionality which we discourage or doesn't work.
14514 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14516 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14517 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14518 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14519 this makes Emacs dump core during garbage collection on rare
14520 occasions. sizeof is obviously inferior to offsetof here, so
14521 stick with offsetof.
14522 (GC_POINTER_ALIGNMENT): New macro.
14523 (mark_memory): Omit 3rd (offset) arg; caller changed.
14524 Don't assume EMACS_INT alignment is the same as pointer alignment.
14526 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14528 * keyboard.c (read_key_sequence_remapped): New var.
14529 (read_key_sequence): Compute remapping in the right buffer.
14530 (command_loop_1): Use read_key_sequence's remapping directly.
14532 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14534 * dired.c (file_name_completion): Don't expand file name.
14535 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14536 before checking file name handler.
14538 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14539 they've been requested explicitly (bug#9591).
14541 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14543 * keymap.c (Fsingle_key_description): Use make_specified_string
14544 instead of build_string to build string from push_key_description.
14547 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14549 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14550 This fixes a Y2038 bug on 64-bit hosts.
14551 * buffer.c (reset_buffer):
14552 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14553 (Fclear_buffer_auto_save_failure):
14554 Use 0, not -1, to represent an unset failure time, since time_t
14555 might not be signed.
14557 Remove dependency on glibc malloc internals.
14558 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14559 Move back here from lisp.h, but with their new implementations.
14560 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14561 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14562 * charset.c (charset_table_init): New static var.
14563 (syms_of_charset): Use it instead of xmalloc. This removes a
14564 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14565 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14566 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14567 Move back to alloc.c.
14568 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14569 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14571 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14573 * nsterm.m (windowDidResize): Call x_set_window_size only when
14574 ns_in_resize is true. Otherwise set pixelwidth/height and
14575 call change_frame_size (Bug#9628).
14577 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14579 Port --enable-checking=all to Fedora 14 x86-64.
14580 * charset.c (syms_of_charset): Also account for glibc malloc's
14581 internal overhead when calculating the initial malloc maximum.
14583 Port --enable-checking=all to Fedora 14 x86.
14584 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14586 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14587 (overrun_check_realloc, overrun_check_free):
14588 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14589 That way, xmalloc returns a properly-aligned pointer even if
14590 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14591 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14592 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14593 into account when calculating the initial malloc maximum.
14594 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14595 Move here from alloc.c, so that charset.c can use it too.
14596 Properly align; the old code wasn't right for common 32-bit hosts
14597 when configured with --enable-checking=all.
14598 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14599 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14601 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14603 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14606 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14608 * xdisp.c (compute_display_string_end): If there's no display
14609 string at CHARPOS, return -1.
14611 * bidi.c (bidi_fetch_char): When compute_display_string_end
14612 returns a negative value, treat the character as a normal
14613 character not covered by a display string. (Bug#9624)
14615 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14617 * lread.c (Fread_from_string): Fix typo in docstring.
14619 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14621 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14622 newline, reseat the iterator instead of bidi-iterating there one
14623 character at a time. (Bug#9610)
14624 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14625 TO_CHARPOS if the bidi iterator is at base embedding level.
14627 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14629 * lread.c (readevalloop): Use correct code for NBSP.
14630 (read1): Likewise. (Bug#9608)
14632 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14634 * dbusbind.c (Fdbus_register_signal): When service is not
14635 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14637 2011-09-25 Glenn Morris <rgm@gnu.org>
14639 * buffer.c (truncate-lines): Doc fix.
14641 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14643 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14644 (Fset_window_next_buffers): Doc fix.
14646 2011-09-24 Glenn Morris <rgm@gnu.org>
14648 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14650 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14652 Fix minor problems found by static checking.
14653 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14654 * indent.c (Fvertical_motion): Fix == vs = typo.
14656 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14658 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14659 Default value is now t. Doc fix.
14661 * indent.c (Fvertical_motion): Compute and apply the overshoot
14662 logic when moving up, not only when moving down. Fix the
14663 confusing name and values of the it_overshoot_expected variable;
14664 logic changes accordingly. (Bug#9254) (Bug#9549)
14666 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14667 CHARPOS is covered by a display string which includes newlines.
14668 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14669 is covered by a display string with embedded newlines.
14671 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14673 * dbusbind.c (Fdbus_register_signal): Add match rule to
14674 Vdbus_registered_objects_table. (Bug#9581)
14675 (Fdbus_register_method, Vdbus_registered_objects_table):
14678 2011-09-24 Jim Meyering <meyering@redhat.com>
14680 do not ignore write error for any output size
14681 The previous change was incomplete.
14682 While it makes emacs --batch detect the vast majority of stdout
14683 write failures, errors were still ignored whenever the output size is
14684 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14685 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14686 && echo FAIL: ignored write error
14687 FAIL: ignored write error
14688 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14689 && echo FAIL: ignored write error
14690 FAIL: ignored write error
14691 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14693 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14695 * emacs.c (Fkill_emacs): In noninteractive mode exit
14696 non-successfully if a write error occurred on stdout. (Bug#9574)

14700 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14703 * dispextern.h (struct it): Update the comment documenting what
14706 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14708 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14709 a display string, extend search for cursor position to end of row.
14710 (find_row_edges): If the row ends in a newline from a display
14711 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14712 Handle the case of a display string with multiple newlines.
14713 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14714 non-empty line. Fixes confusing cursor motion with arrow keys at
14715 the beginning of a line that starts with whitespace.
14717 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14719 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14722 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14724 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14725 boolean (Bug#9154).
14727 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14729 * xdisp.c (display_line): Record maximum and minimum buffer
14730 positions even if no glyphs were produced (e.g., by a zero-width
14731 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14732 buffer positions that will be removed from the glyph row because
14734 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14735 column is beyond frame width: don't subtract 1 "pixel" when
14736 computing width of the stretch.
14737 (reseat_at_next_visible_line_start): Undo the change made on
14738 2011-09-17 that saved paragraph information and restored it after
14739 the call to `reseat'. (Bug#9545)
14741 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14743 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14744 and turn window cursor on if cleared (Bug#9415).
14746 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14748 * search.c (boyer_moore): Take unibyte characters from pattern
14749 literally. (Bug#9458)
14751 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14753 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14755 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14757 Fix minor problem found by static checking.
14758 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14759 initialized, to pacify gcc -Wuninitialized.
14761 * fileio.c: Report proper errno when syscall falls.
14762 (Finsert_file_contents): Save and restore errno,
14763 so that report_file_error outputs the correct diagnostic.
14764 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14766 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14768 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14770 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14772 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14773 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14775 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14777 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14778 about the current paragraph and restore it after the call to reseat.
14780 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14781 (bidi_find_paragraph_start): Search back for paragraph beginning
14782 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14783 (bidi_move_to_visually_next): Only trigger paragraph-related
14784 computations when the last character is a newline or at EOB, not
14785 just any NEUTRAL_B. (Bug#9470)
14787 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14788 truncated lines if point is covered by a display string. (Bug#9524)
14790 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14792 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14793 (cons_to_x_long): New function.
14794 (lisp_data_to_selection_data): Use it. Correct the test for
14795 short-versus-long data; it was negated. Break out of vector
14796 loop, for efficiency, when a long datum is discovered.
14798 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14800 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14802 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14804 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14805 GCC PR/17406) by declaring this function with external scope.
14807 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14809 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14810 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14812 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14814 * editfns.c (Fformat): Correctly handle text properties on "%%".
14816 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14818 * xterm.c (x_draw_composite_glyph_string_foreground):

14820 * term.c (encode_terminal_code):
14821 * composite.c (composition_update_it, get_composition_id):
14822 * xdisp.c (get_next_display_element)
14823 (fill_composite_glyph_string): Add comments about special meaning
14824 of TAB characters in a composition.
14826 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14828 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14829 This occurs when processing a multibyte format.
14830 Problem reported by Wolfgang Jenker.
14832 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14834 * xdisp.c (try_cursor_movement): Only check for exact match if
14835 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14837 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14839 Remove unused external symbols.
14840 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14841 * xdisp.c (calc_pixel_width_or_height): Now static.
14842 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14843 * indent.c (check_display_width):
14844 * w32term.c: Fix comment to match code.
14845 * xterm.c, xterm.h (x_catching_errors): Remove.
14847 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14849 * xselect.c: Use signed conversions more consistently (Bug#9498).
14850 (selection_data_to_lisp_data): Assume incoming selection data are
14851 signed integers, not unsigned. This is to be consistent with
14852 outgoing selection data, which was modified to use signed integers
14853 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14854 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14855 expects long, not unsigned long.
14857 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14859 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14860 computation of loop end. Reported by Johan Bockgård
14863 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14865 * frame.c (Fother_visible_frames_p): Function deleted.
14867 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14869 * indent.c (compute_motion): Process display vector front to back
14870 rather than the other way around. (Bug#2496)
14872 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14874 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14876 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14878 * minibuf.c (Fread_from_minibuffer): Doc fix.
14880 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14882 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14883 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14885 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14887 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14888 value for non-existent files.
14890 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14892 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14893 set its "size" to -1. This will set the modtime_size field of
14894 the corresponding buffer to -1, which is what
14895 verify-visited-file-modtime expects for files that do not exist.
14898 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14900 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14902 * lisp.h: ... from here. push_key_description is no longer
14903 defined in keyboard.c, so its declaration should not be in
14904 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14905 logically belongs with push_key_description.
14907 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14909 * buffer.h: Include <sys/types.h> instead of <time.h>.
14910 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14911 Problem reported by Herbert J. Skuhra.
14913 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14915 * xml.c (parse_region): Make the parsing work for
14916 non-comment-starting XML files again (bug#9144).
14918 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14920 * image.c (gif_load): Fix calculation of bottom and right corner.
14923 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14925 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14926 redisplay in small windows.
14928 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14930 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14932 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14934 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14935 Operate on live windows only.
14937 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14939 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14941 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14943 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14944 only under bidi iteration.
14946 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14948 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14950 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14952 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14953 Without this fix, the command to link temacs failed due to an
14954 undefined symbol __builtin_isnan. This is because
14955 /usr/include/iso/math_c99.h #defines isnan(x) to
14956 __builtin_isnan(x), but the bundled gcc, which identifies itself
14957 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14959 * floatfns.c (isnan): #undef, and then #define to a clone of
14961 (Fisnan): Always define, since it's always available now.
14962 (syms_of_floatfns): Always define isnan at the Lisp level.
14964 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14966 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14968 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14970 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14971 The previous code assumed that file offsets (off_t values) fit in
14972 EMACS_INT variables, which is not true on typical 32-bit hosts.
14973 The code messed up by falsely reporting buffer overflow in cases
14974 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14975 when "big" contains more than 2**29 bytes, even though this
14976 inserts just one byte and does not overflow the buffer.
14977 (Finsert_file_contents): Store file offsets as off_t
14978 values, not as EMACS_INT values. Check for overflow when
14979 converting between EMACS_INT and off_t. When checking for
14980 buffer overflow or for overlap, take the offsets into account.
14981 Don't use EMACS_INT for small values where int suffices.
14982 When checking for overlap, fix a typo: ZV was used where
14983 ZV_BYTE was intended.
14984 (Fwrite_region): Don't assume off_t fits into 'long'.
14985 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14987 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14989 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14991 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14993 sprintf-related integer and memory overflow issues (Bug#9412).
14995 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14996 (esprintf, exprintf, evxprintf): New functions.
14997 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14998 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14999 (modify_event_symbol): Do not assume that the length of
15000 name_alist_or_stem is safe to alloca and fits in int.
15001 (Fexecute_extended_command): Likewise for function name and binding.
15002 (Frecursion_depth): Wrap around reliably on integer overflow.
15003 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15004 since some callers pass EMACS_INT values.
15005 (Fsingle_key_description): Don't crash if symbol name contains more
15006 than MAX_ALLOCA bytes.
15007 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15008 (get_minibuffer): Arg is now EMACS_INT, not int.
15009 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15010 (esprintf, exprintf, evxprintf): New decls.
15011 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15013 * dbusbind.c (signature_cat): New function.
15014 (xd_signature, Fdbus_register_signal):
15015 Do not overrun buffer; instead, report string overflow.
15017 * dispnew.c (add_window_display_history): Don't overrun buffer.
15018 Truncate instead; this is OK since it's just a log.
15020 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15021 even if the time zone offset is outlandishly large.
15022 Don't mishandle offset == INT_MIN.
15024 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15025 when creating daemon; the previous buffer-overflow check was incorrect.
15027 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15028 which has the guts of the old verror function.
15030 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15031 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15033 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15034 (font_unparse_xlfd): Don't blindly alloca long strings.
15035 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15036 fits in int, when using sprintf. Use single snprintf to count
15037 length of string rather than counting it via multiple sprintfs;
15038 that's simpler and more reliable.
15039 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15040 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15041 sprintf, in case result does not fit in int.
15043 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15044 (fontset_from_font): Print it.
15046 * frame.c (tty_frame_count): Now printmax_t, not int.
15047 (make_terminal_frame, set_term_frame_name): Print it.
15048 (x_report_frame_params): In X, window IDs are unsigned long,
15049 not signed long, so print them as unsigned.
15050 (validate_x_resource_name): Check for implausibly long names,
15051 and don't assume name length fits in 'int'.
15052 (x_get_resource_string): Don't blindly alloca invocation name;
15053 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15056 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15057 (xg_check_special_colors, xg_set_geometry):
15058 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15060 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15061 Use esprintf, not sprintf, in case result does not fit in int.
15063 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15064 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15065 it as a large positive number.
15066 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15067 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15069 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15070 in case result does not fit in int.
15072 * print.c (float_to_string): Detect width overflow more reliably.
15073 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15074 buffer overrun. Don't assume list length fits in 'int'. Treat
15075 print length of 0 as 0, not as infinity; to be consistent with other
15076 uses of print length in this function. Don't overflow print length
15077 index. Don't assume hash table size fits in 'long', or that
15078 vectorlike size fits in 'unsigned long'.
15080 * process.c (make_process): Use printmax_t, not int, to format
15081 process-name gensyms.
15083 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15085 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15086 to avoid potential buffer overrun.
15088 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15089 if X resource line is longer than 512 bytes.
15091 * xfns.c (x_window): Make sprintf buffer a bit bigger
15092 to avoid potential buffer overrun.
15094 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15096 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15098 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15100 Integer overflow fixes for scrolling, etc.
15101 Without these, Emacs silently mishandles large integers sometimes.
15102 For example, "C-u 4294967297 M-x recenter" was treated as if
15103 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15105 * xdisp.c (try_window_id): Check Emacs fixnum range before
15106 converting to 'int'.
15108 * window.c (window_scroll_line_based, Frecenter):
15109 Check that an Emacs fixnum is in range before assigning it to 'int'.
15110 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15111 values converted from Emacs fixnums.
15112 (Frecenter): Don't wrap around a line count if it is out of 'int'
15113 range; instead, treat it as an extreme value.
15114 (Fset_window_configuration, compare_window_configurations):
15115 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15117 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15118 that can exceed INT_MAX. Check that EMACS_INT value is in range
15119 before assigning it to the (possibly-narrower) index.
15120 (match_limit): Don't assume that a fixnum can fit in 'int'.
15122 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15125 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15126 (Fvertical_motion): Don't wrap around LINES values that don't fit
15127 in 'int'. Instead, treat them as extreme values. This is good
15128 enough for windows, which can't have more than INT_MAX lines anyway.
15130 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15132 * Require libxml/parser.h to avoid compilation warning.
15134 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15136 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15137 since this reportedly can destroy thread storage.
15139 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15141 * syntax.c (find_defun_start): Update all cache variables if
15142 exiting early (Bug#9401).
15144 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15146 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15148 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15149 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15150 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15152 * term.c (tty_append_glyph): New function.
15153 (produce_stretch_glyph): Static function and its prototype deleted.

15160 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15161 when checking :margin (Bug#9390).
15162 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15163 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15164 so that the name doesn't mislead. All uses changed.
15166 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15168 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15171 2011-08-27 Eli Zaretskii <eliz@gnu.org>

15174 position beyond to_charpos, if we are scanning backwards.
15175 (move_it_vertically_backward): When DY == 0, make sure we get to
15176 the first character in the line after the newline.
15178 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15180 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15181 (ccl_driver): Do not generate an out-of-range pointer.
15182 (Fccl_execute_on_string): Remove unnecessary check for
15183 integer overflow, noted by Stefan Monnier in
15184 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15185 Remove a FIXME that didn't need fixing.
15186 Simplify the newly-introduced buffer reallocation code.
15188 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15190 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15192 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15194 Integer and memory overflow issues (Bug#9196).
15196 * doc.c (get_doc_string): Rework so that
15197 get_doc_string_buffer_size is the actual buffer size, rather than
15198 being 1 less than the actual buffer size; this makes xpalloc more
15201 * image.c (x_allocate_bitmap_record, cache_image):
15202 * xselect.c (Fx_register_dnd_atom):
15203 Simplify previous changes by using xpalloc.
15205 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15206 since either will do and ptrdiff_t is convenient with xpalloc.
15208 * charset.c (charset_table_size)
15209 (struct charset_sort_data.priority): Now ptrdiff_t.
15210 (charset_compare): Don't overflow if priorities differ greatly.
15211 (Fsort_charsets): Don't assume list length fits in int.
15212 Check for size-calculation overflow when allocating sort data.
15213 (syms_of_charset): Allocate an initial charset table that is
15214 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15216 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15218 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15219 The actual value is always <= INT_MAX, and leaving it unsigned made
15220 overflow checking harder.
15222 * dispextern.h (struct glyph_matrix.rows_allocated)
15223 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15224 with xpalloc. The values are still always <= INT_MAX.
15226 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15228 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15229 (SAFE_NALLOCA): New macro.
15231 * region-cache.c (struct boundary.pos, find_cache_boundary)
15232 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15233 (set_cache_region, invalidate_region_cache)
15234 (revalidate_region_cache, know_region_cache, region_cache_forward)
15235 (region_cache_backward, pp_cache):
15236 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15237 so that ptrdiff_t * can be passed to xpalloc.
15238 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15239 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15240 (pp_cache): Don't assume cache_len fits in int.
15241 * region-cache.h: Adjust extern decls to match.
15243 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15244 EMACS_INT, since either will do, for xpalloc.
15246 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15247 (xnmalloc, xnrealloc, xpalloc): New functions.
15249 * bidi.c (bidi_shelve_header_size): New constant.
15250 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15251 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15253 * bidi.c (bidi_cache_shrink):
15254 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15256 Don't update size of array until after memory allocation succeeds,
15257 because xmalloc/xrealloc may not return.
15258 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15259 now that we have proper integer overflow checking.
15260 (record_overlay_string, overlay_strings): Catch overflows when
15261 calculating size of overlay_str_buf.
15263 * callproc.c (Fcall_process): Check for size overflow when
15264 calculating size of args2.
15265 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15266 Normally we prefer signed values, but sticking with ptrdiff_t would
15267 require adding more-complicated checks.
15269 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15270 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15271 Redo buffer-overflow calculations to avoid integer overflow.
15272 Add a FIXME comment where memory seems to be over-allocated.
15274 * character.c (Fstring): Check for size-calculation overflow.
15276 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15277 unnecessary integer overflow. Check for size overflow.
15278 (encode_coding_object): Don't update size until xmalloc succeeds.
15280 * composite.c (get_composition_id): Check for overflow in glyph
15281 length calculations.
15283 Integer and memory overflow fixes for display code.
15284 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15285 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15286 (scrolling_window): Check for overflow in size calculations.

15298 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15299 (get_doc_string): Check for size calculation overflow.
15300 Don't update size until allocation succeeds.
15301 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15302 EMACS_INT, where ptrdiff_t will do.
15303 (Fsubstitute_command_keys): Check for string overflow.
15305 * editfns.c (set_time_zone_rule): Don't assume environment length
15307 (message_length): Now ptrdiff_t, not int.
15308 (Fmessage_box): Don't update size until allocation succeeds.
15309 Don't assume message length fits in int.
15310 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15312 * emacs.c (main): Do not reallocate argv, since there is a null at
15313 the end that can be overwritten, and this way there's no need to
15314 worry about size-calculation overflow.
15315 (sort_args): Check for size-calculation overflow.
15317 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15319 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15321 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15322 (x_set_scroll_bar_width, x_figure_window_size):
15323 Check for integer overflow.
15324 (x_set_alpha): Do not assume XINT fits in int.
15326 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15327 This is for the members text_lines, text_cols, total_lines, total_cols,
15328 where the system imposes an 'int' limit.
15330 * fringe.c (Fdefine_fringe_bitmap):
15331 Don't update size until alloc works.
15333 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15334 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15336 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15337 Check for size-calculation overflow.
15338 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15339 do, as we prefer signed integers.
15340 (id_to_widget.max_size, id_to_widget.used)
15341 (xg_store_widget_in_map, xg_remove_widget_from_map)
15342 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15343 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15344 Use and return ptrdiff_t, not int.
15345 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15346 * gtkutil.h: Change prototypes to match the above.
15348 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15349 are duplicate now that they've been promoted to lisp.h.
15350 (x_allocate_bitmap_record, x_alloc_image_color)
15351 (make_image_cache, cache_image, xpm_load):
15352 Don't update size until alloc is done.

15363 Use ptrdiff_t, not int, to count maps.
15364 (read_char_minibuf_menu_prompt): Check for overflow in size
15365 calculations. Don't update size until allocation succeeds.
15366 Redo calculations to avoid overflow.
15367 * keyboard.h: Change prototypes to match the above.
15369 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

15395 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15396 for command line length. Do not attempt to address one before the
15397 beginning of an array, as that's not portable.
15399 * term.c (max_frame_lines): Remove; unused.
15400 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15402 (encode_terminal_code, calculate_costs): Check for size
15403 calculation overflow.

15409 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15410 subtracting pointers.
15411 (gobble_line): Check for overflow more carefully. Don't update size
15414 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

15425 Use ptrdiff_t, not int, for sizes.
15426 (Finternal_make_lisp_face, cache_face):
15427 Check for size calculation overflow.
15428 (cache_face): Treat size calculation overflows as if they were
15429 memory exhaustion (the usual treatment), rather than aborting.
15431 * xfns.c (x_encode_text, x_set_name_internal)
15432 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15433 sizes, since they can exceed INT_MAX in size. Check for size
15434 calculation overflow.
15436 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15437 (xg_select): Check for size calculation overflow.
15438 Don't update size until alloc done.
15440 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15441 as sprintf is limited to int lengths.
15443 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15444 (X_LONG_MIN): New macros.
15445 Use them to make the following changes clearer.
15446 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15447 This change doesn't affect the value now, but it may help remind
15448 future maintainers not to raise the value too much later.
15449 (SELECTION_QUANTUM): Remove, replacing with ...
15450 (selection_quantum): ... new function, which avoids overflow.
15452 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15453 assumption that selection length fits in 'int'.

15466 (lisp_data_to_selection_data, x_property_data_to_lisp):

15468 (x_get_window_property, receive_incremental_selection)
15469 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15470 Don't store size until memory allocation succeeds.
15471 (x_get_window_property): Plug memory leak on memory exhaustion.
15472 Don't double-block input; malloc is safe here. Don't assume 2**34
15473 - 4 fits in unsigned long. Add an xassert to check
15474 XGetWindowProperty overflow. Be more careful about overflow
15475 calculations, and distinguish size from memory overflow better.
15476 (receive_incremental_selection): When tracing, don't assume
15477 unsigned int is less than INT_MAX.
15478 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15479 harmful) conversions of unsigned short to int.
15480 (lisp_data_to_selection_data): Don't assume that integers
15481 in the range -65535 through -1 fit in an X unsigned short.
15482 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15483 result parameters unless successful. Rely on cons_to_unsigned
15484 to report problems with elements; the old code wasn't right anyway.
15485 (x_check_property_data): Check for int overflow; we cannot use
15486 a wider type due to X limits.
15487 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15489 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15519 * lisp.h (hash_lookup, hash_put):
15520 * minibuf.c (Ftest_completion):
15521 Use ptrdiff_t for hash table indexes, not int (which is too
15522 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15523 32-bit --with-wide-int hosts).
15525 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15526 Add a FIXME comment about memory leaks.
15527 (syms_of_charset): Don't assume xmalloc returns.

15531 * character.h (CHAR_WIDTH):
15532 * indent.c (MULTIBYTE_BYTES_WIDTH):
15533 Use sanitize_char_width to avoid undefined and/or bad behavior
15534 with outlandish widths.
15535 * character.h (sanitize_tab_width): Rename from sanitize_width,
15536 now that we have two such functions. All uses changed.
15537 (sanitize_char_width): New inline function.
15539 Don't assume that tab-width fits in int.

15547 * fileio.c: Integer overflow issues with file modes.
15548 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15550 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

15557 exceed limits imposed by XClientMessageEvent, as well as the usual
15558 ptrdiff_t and size_t limits.
15560 * keyboard.c: Overflow, signedness and related fixes.
15561 (make_lispy_movement): Use same integer type in forward decl
15562 that is used in the definition.
15563 (read_key_sequence, keyremap_step):
15564 Change bufsize argument back to int, undoing my 2011-03-30 change.
15565 We prefer signed types, and int is wide enough here.
15566 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15567 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15568 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15569 length, not size_t. Use ptrdiff_t for index, not int.
15570 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15571 possibility of integer overflow.
15573 Overflow, signedness and related fixes for images.

15599 Prefer int to unsigned where either will do.
15600 (tiff_handler): New function, combining the cores of the
15601 old tiff_error_handler and tiff_warning_handler.
15602 This function is rewritten to use vsnprintf and thereby avoid
15603 stack buffer overflows. It uses only the features of vsnprintf
15604 that are common to both POSIX and native Microsoft.
15605 (tiff_error_handler, tiff_warning_handler): Use it.
15606 (tiff_load, gif_load, imagemagick_load_image):
15607 Don't assume :index value fits in 'int'.

15609 (imagemagick_load_image): Check that crop parameters fit into
15610 the integer types that MagickCropImage accepts. Don't assume
15611 Vimagemagick_render_type has a nonnegative value. Don't assume
15612 size_t fits in 'long'.
15613 (gs_load): Use printmax_t to print the widest integers possible.
15614 Check for integer overflow when computing image height and width.
15616 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15618 * xdisp.c (redisplay_window): Don't force window start if point

15627 (handle_single_display_spec): If the display spec is of the form
15628 `(space ...)', and specifies display in the text area, return 2
15630 (try_cursor_movement): Check for the need to scroll more
15631 accurately, and prefer exact match for point under bidi.
15632 Don't advance `row' beyond the last row of the window.
15634 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15635 into disp_prop; all users changed.

15650 buffers, return left-to-right.
15651 (set_cursor_from_row): Consider candidate row a win if its glyph
15652 represents a newline and point is on that newline. Fixes cursor
15653 positioning on the newline at EOL of R2L text within L2R
15654 paragraph, and vice versa.
15655 (try_cursor_movement): Check continued rows, in addition to
15656 continuation rows. Fixes unwarranted scroll when point enters a
15657 continued line of R2L text within an L2R paragraph, or vice versa.
15658 (cursor_row_p): Consider the case of point being equal to
15659 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15660 from the end of a short line to the beginning of a continued line
15661 of R2L text within L2R paragraph.

15685 * xdisp.c (redisplay_window): When computing centering_position,
15686 account for the height of the header line. (Bug#8874)
15688 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15689 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15690 candidate is selected by the mouse, and that candidate has a
15691 composed character under the mouse.
15693 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15694 coordinates reported by pos-visible-in-window-p for a composed
15695 character in column zero.
15697 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15704 consider it a hit if to_charpos is anywhere in the range of the
15705 composed buffer positions.
15707 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15709 * image.c (gif_load): Don't assume that each subimage has the same
15710 dimensions as the base image. Handle disposal method that is
15711 "undefined" by the gif spec (Bug#9335).
15713 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15715 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15720 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15721 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15722 from an Org mode buffer to a Speedbar frame.
15724 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15725 a composition, take its buffer position from IT->cmp_it.charpos.
15726 Fixes cursor positioning at the beginning of a line that begins
15727 with a composed character.
15729 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15731 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15732 character bidirectional type, use STRONG_L instead. Fixes crashes
15733 in a buffer produced by `describe-categories'.
15735 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15736 members before the level stack, so they would be saved and
15737 restored when copying iterator state. Fixes incorrect reordering
15738 around TABs covered by display properties.
15740 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15742 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15828 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15829 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15830 the event loop (Bug#7276).

15873 buffer/string position, to be restored by pop_it. Fix flags in
15874 the iterator structure wrt the object coming from a display
15875 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15876 properties. (Bug#9284)

16053 (x_set_background_color): Likewise.
16055 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16056 contents (Bug#9176).
16057 (EmacsTooltip -init): Remove bezels and add shadows to
16060 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16061 or scroll bar (Bug#8470).
16063 * nsfont.m (nsfont_open): Remove assignment to voffset and
16064 unnecessary vars hshink, expand, hd, full_height, min_height.
16065 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16067 * nsterm.h (nsfont_info): Remove voffset field.
16069 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16071 Implement strike-through and overline on NextStep (Bug#8863).
16073 * nsfont.m (nsfont_open): Use underline position provided by font,
16074 instead of hard-coded value of 2.
16075 (nsfont_draw): Call ns_draw_text_decoration instead.
16077 * nsterm.h: Add declaration for ns_draw_text_decoration.
16079 * nsterm.m (ns_draw_text_decoration): New function for drawing
16080 underline, overline, and strike-through.
16081 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16082 ns_draw_text_decoration. Change treatment of cursor drawing to
16083 accommodate underlining, etc.
16085 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16087 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16090 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16092 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16093 Without this fix, if a signal arrives just after memory fills up,
16094 'malloc' might be invoked reentrantly.
16096 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16097 In other words, assume that every image size is allowed, on non-X
16098 hosts. This assumption is probably wrong, but it lets Emacs compile.
16100 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16102 * regex.c (re_iswctype): Convert return values to boolean.
16104 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16106 * xdisp.c (compute_display_string_pos): Don't use cached display
16107 string position if the buffer had its restriction changed.
16110 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16112 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16114 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16116 Integer signedness and overflow and related fixes. (Bug#9079)
16118 * bidi.c: Integer size and overflow fixes.
16119 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16120 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16121 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16122 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16123 (bidi_find_other_level_edge):
16124 Use ptrdiff_t instead of EMACS_INT where either will do.
16125 This works better on 32-bit hosts configured --with-wide-int.
16126 (bidi_cache_ensure_space): Check for size-calculation overflow.
16127 Use % rather than repeated addition, for better worst-case speed.
16128 Don't set bidi_cache_size until after xrealloc returns, because it
16130 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16131 (bidi_cache_ensure_space): Also check that the bidi cache size
16132 does not exceed that of the largest Lisp string or buffer. See Eli
16133 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16135 * alloc.c (__malloc_size_t): Remove.
16136 All uses replaced by size_t. See Andreas Schwab's note
16137 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16139 * image.c: Improve checking for integer overflow.
16140 (check_image_size): Assume that f is nonnull, since
16141 it is always nonnull in practice. This is one less thing to
16142 worry about when checking for integer overflow later.
16143 (x_check_image_size): New function, which checks for integer
16144 overflow issues inside X.
16145 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16146 This removes the need for a memory_full check.
16147 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16148 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16149 (xbm_read_bitmap_data): Change locals back to 'int', since
16150 their values must fit in 'int'.
16151 (xpm_load_image, png_load, tiff_load):
16152 Invoke x_create_x_image_and_pixmap earlier,
16153 to avoid much needless work if the image is too large.
16154 (tiff_load): Treat overly large images as if
16155 x_create_x_image_and_pixmap failed, not as malloc failures.
16156 (gs_load): Use x_check_image_size.
16158 * gtkutil.c: Omit integer casts.
16159 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16160 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16162 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16164 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16165 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16166 would wrongly return t on a 64-bit host.
16168 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16169 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16170 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16171 and therefore cause GCC to emit a bogus diagnostic in some cases.
16173 * image.c: Integer signedness and overflow and related fixes.
16174 This is not an exhaustive set of fixes, but it's time to
16175 record what I've got.
16176 (lookup_pixel_color, check_image_size): Remove redundant decls.
16177 (check_image_size): Don't assume that arbitrary EMACS_INT values
16178 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16179 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16180 (tiff_load, imagemagick_load_image):
16181 Check for overflow in size calculations.
16182 (x_create_x_image_and_pixmap): Remove unnecessary test for
16183 xmalloc returning NULL; that can't happen.
16184 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16185 (xpm_color_bucket): Use better integer hashing function.
16186 (xpm_cache_color): Don't possibly over-allocate memory.
16187 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16188 (gif_memory_source):
16189 Use ptrdiff_t, not int or size_t, to record sizes.
16190 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16191 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16192 either works, as we prefer signed integers.
16193 (tiff_read_from_memory, tiff_write_from_memory):
16194 Return tsize_t, not size_t, since that's what the TIFF API wants.
16195 (tiff_read_from_memory): Don't fail simply because the read would
16196 go past EOF; instead, return a short read.
16197 (tiff_load): Omit no-longer-needed casts.
16198 (Fimagemagick_types): Don't assume size fits into 'int'.
16200 Improve hashing quality when configured --with-wide-int.
16201 * fns.c (hash_string): New function, taken from sxhash_string.
16202 Do not discard information about ASCII character case; this
16203 discarding is no longer needed.
16204 (sxhash-string): Use it. Change sig to match it. Caller changed.
16205 * lisp.h: Declare it.
16206 * lread.c (hash_string): Remove, since we now use fns.c's version.
16207 The fns.c version returns a wider integer if --with-wide-int is
16208 specified, so this should help the quality of the hashing a bit.
16210 * emacs.c: Integer overflow minor fix.
16211 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16212 Define only if GNU_LINUX.
16213 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16215 * dispnew.c: Integer signedness and overflow fixes.
16216 Remove unnecessary forward decls, that were a maintenance hassle.
16217 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16219 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16220 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16221 (prepare_desired_row, line_draw_cost):
16222 Use int, not unsigned, where either works.
16223 (save_current_matrix, restore_current_matrix):
16224 Use ptrdiff_t, not size_t, where either works.
16225 (init_display): Check for overflow more accurately, and without
16226 relying on undefined behavior.
16228 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16229 Remove, replacing with the new symbols in lisp.h. All uses changed.
16230 * fileio.c (make_temp_name):
16231 * filelock.c (lock_file_1, lock_file):
16232 * xdisp.c (message_dolog):
16233 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16234 Use pMd etc. instead.
16235 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16236 replacing the pWIDE etc. symbols removed from editfns.c.
16238 * keyboard.h (num_input_events): Now uintmax_t.
16239 This is (very slightly) less likely to mess up due to wraparound.
16242 * buffer.c: Integer signedness fixes.
16243 (alloc_buffer_text, enlarge_buffer_text):
16244 Use ptrdiff_t rather than size_t when either will do, as we prefer
16247 * alloc.c: Integer signedness and overflow fixes.
16248 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16249 (__malloc_size_t): Default to size_t, not to int.
16250 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16251 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16252 Prefer ptrdiff_t to size_t when either would do, as we prefer
16254 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16255 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16256 Now const. Initialize with values that are in range even if char
16258 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16259 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16260 These functions do the right thing with sizes > 2**32.
16261 (check_depth): Now ptrdiff_t, not int.
16262 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16263 Adjust to new way of storing sizes. Check for size overflow bugs
16265 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16266 slightly wrong anyway, as it missed one instance of
16267 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16268 (refill_memory_reserve): Omit needless cast to size_t.
16269 (mark_object_loop_halt): Mark as externally visible.
16271 * xselect.c: Integer signedness and overflow fixes.
16272 (Fx_register_dnd_atom, x_handle_dnd_message):
16273 Use ptrdiff_t, not size_t, since we prefer signed.
16274 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16275 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16276 x_dnd_atoms_size and x_dnd_atoms_length.
16278 * doprnt.c: Prefer signed to unsigned when either works.
16280 * doprnt.c (doprnt):
16282 * xdisp.c (vmessage):
16283 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16284 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16285 prefer signed arithmetic to avoid comparison confusion.
16286 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16287 but is a bit tricky.
16289 Assume freestanding C89 headers, string.h, stdlib.h.
16290 * data.c, doprnt.c, floatfns.c, print.c:
16291 Include float.h unconditionally.
16292 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16293 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16294 * regex.c: Likewise for stddef.h, string.h.
16295 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16296 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16297 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16298 (STDC_HEADERS): Remove obsolete defines.
16299 * sysdep.c: Include limits.h unconditionally.
16301 Assume support for memcmp, memcpy, memmove, memset.
16302 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16303 * regex.c (memcmp, memcpy):
16304 Remove; we assume C89 now.
16306 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16307 (__malloc_safe_bcopy): Remove; no longer needed.
16309 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16310 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16311 well either way, and we prefer signed to unsigned.
16313 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16315 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16316 closes the connection while we're reading (bug#9182).
16318 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16320 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16321 are specified (Bug#9168).
16323 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16325 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16326 Found by GCC static checking and --with-wide-int on a 32-bit host.
16328 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16330 * xdisp.c (compute_display_string_pos): Fix logic of caching
16331 previous display string position. Initialize cached_prev_pos to
16332 -1. Fixes slow-down at the beginning of a buffer.
16334 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16336 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16337 for attrs[LFACE_FONTSET_INDEX].
16339 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16341 * xml.c (parse_region): Remove unused local
16342 that was recently introduced.
16344 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16346 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16347 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16349 * xdisp.c (move_it_in_display_line_to): Record the best matching
16350 position for TO_CHARPOS while scanning the line, and restore it on
16351 exit if none of the characters scanned was an exact match.
16352 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16353 when exact match is impossible due to invisible text, and the
16354 lines are truncated.
16356 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16358 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16361 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16363 Fix a significant slow-down of cursor motion with C-n, C-p,
16364 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16365 auto-repeat under bidi redisplay in fontified buffers.
16366 * xdisp.c (compute_stop_pos_backwards): New function.
16367 (next_element_from_buffer): Call compute_stop_pos_backwards to
16368 find a suitable prev_stop when we find ourselves before
16370 (reseat): Don't look for prev_stop, as that could mean a very long
16372 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16373 <cached_disp_overlay_modiff>: Cache for last found display string
16375 (compute_display_string_pos): Return the cached position if asked
16376 about the same buffer in the same area of character positions, and
16377 the buffer wasn't changed since the time the display string
16378 position was cached.
16380 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16382 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16383 is an integer, which is important for empty lines. (Bug#9149)
16385 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16387 * frame.c (Fmodify_frame_parameters): In tty case, update the
16388 default face if necessary (Bug#4238).
16390 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16392 * editfns.c (Fstring_to_char): No need to explain what a character
16393 is in the docstring (Bug#6576).
16395 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16397 * xml.c (parse_region): Make sure we always return a tree.
16399 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16401 * xml.c (parse_region): If a document contains only comments,
16404 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16406 * xml.c (make_dom): Return comments, too.
16408 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16411 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16412 and the surrounding thread.
16413 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16414 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16415 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16417 * s/openbsd.h (BROKEN_SIGIO): Define.
16418 * unexelf.c (unexec) [__OpenBSD__]:
16419 Don't update the .mdebug section of the Alpha COFF symbol table.
16421 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16423 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16426 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16428 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16429 This fixes some race conditions on the permissions of any newly
16432 * alloc.c (valid_pointer_p): Use pipe, not open.
16433 This fixes some permissions issues when debugging.
16435 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16436 If fchown fails to set both uid and gid, try to set just gid,
16437 as that is sometimes allowed. Adjust the file's mode to eliminate
16438 setuid or setgid bits that are inappropriate if fchown fails.
16440 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16442 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16443 to compare Lisp_Objects.
16444 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16445 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16446 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16448 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16450 * lread.c (read_integer): Unread even EOF character.
16451 (read1): Likewise. Properly record start position of symbol.
16453 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16454 symbol character follows.
16456 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16458 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16459 This works around a problem with the previous change to Fcopy_file.
16460 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16461 and without this change, GCC might complain about discarding
16462 fchown's return value.
16464 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16466 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16468 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16470 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16472 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16474 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16475 it's used from the C level.
16477 * process.c: Use the same condition for POLL_FOR_INPUT in both
16478 keyboard.c and process.c (bug#1858).
16480 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16482 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16483 (Fgnutls_boot): Use it.
16485 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16487 * doc.c (Fsubstitute_command_keys): Revert last change.
16489 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16491 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16492 quotes the next character, and doesn't affect other longer
16493 sequences (bug#8935).
16495 * lread.c (syms_of_lread): Clarify that is isn't only

16507 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16508 (elsz): Now a signed constant, not a size_t var. We prefer signed
16509 types to unsigned, to avoid integer comparison confusion. Without

16560 the iterator is before prev_stop.
16561 (init_iterator): Initialize bidi_p from the default value of

17079 Random fixes. E.g., (random) never returned negative values.
17080 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17081 subseconds part to the entropy, as that's a bit more random.
17082 Prefer signed to unsigned, since the signedness doesn't matter and
17083 in general we prefer signed. When given a limit, use a
17084 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17085 latter isn't right if USE_2_TAGS_FOR_INTS.
17086 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17087 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17104 * buffer.c (Foverlay_put): Say what the return value is
17107 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17111 error be more correct.
17113 * fns.c (Frequire): Remove the mention of the .gz files, since

17127 Qgnutls_bootprop_verify_error (which is no longer used).
17129 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17130 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17131 Also (re)move comments that are misplaced or no longer relevant.

17232 * eval.c (struct backtrace): Simplify and port the data structure.
17233 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17234 signed bit field, as this assumption is not portable and it makes
17235 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17236 "char debug_on_exit : 1" as this is not portable either; instead,
17237 use the portable "unsigned int debug_on_exit : 1". Remove unused
17238 member evalargs. Remove obsolete comments about cc bombing out.

17398 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
17400 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
17402 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17404 Integer and buffer overflow fixes (Bug#8873).
17406 * print.c (printchar, strout): Check for string overflow.
17407 (PRINTPREPARE, printchar, strout):
17408 Don't set size unless allocation succeeds.
17410 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17411 for sizes. Check for string overflow more accurately.
17412 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17414 * macros.c: Integer and buffer overflow fixes.
17415 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17416 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17417 Use ptrdiff_t, not int, for sizes.
17418 Don't increment bufsize until after realloc succeeds.
17419 Check for size-calculation overflow.
17420 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17422 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17424 * lread.c: Integer overflow fixes.
17425 (read_integer): Radix is now EMACS_INT, not int,
17426 to improve quality of diagnostics for out-of-range radices.
17427 Calculate buffer size correctly for out-of-range radices.
17428 (read1): Check for integer overflow in radices, and in
17429 read-circle numbers.
17430 (read_escape): Avoid int overflow.
17431 (Fload, openp, read_buffer_size, read1)
17432 (substitute_object_recurse, read_vector, read_list, map_obarray):
17433 Use ptrdiff_t, not int, for sizes.
17434 (read1): Use EMACS_INT, not int, for sizes.
17435 Check for size overflow.
17437 * image.c (cache_image): Check for size arithmetic overflow.
17439 * lread.c: Integer overflow issues.
17440 (saved_doc_string_size, saved_doc_string_length)
17441 (prev_saved_doc_string_size, prev_saved_doc_string_length):
17442 Now ptrdiff_t, not int.
17443 (read1): Don't assume doc string length fits in int. Check for
17444 out-of-range doc string lengths.
17445 (read_list): Don't assume file position fits in int.
17446 (read_escape): Check for hex character overflow.
17448 2011-06-22 Leo Liu <sdl.web@gmail.com>
17450 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17451 Move to minibuffer.el.
17453 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17455 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17456 The following patches are for when GLYPH_DEBUG && !XASSERT.
17457 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17458 * dispnew.c (flush_stdout):
17459 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17460 Mark as externally visible.
17461 * dispnew.c (check_window_matrix_pointers): Now static.
17462 * dispnew.c (window_to_frame_vpos):
17463 * xfns.c (unwind_create_frame):
17464 * xterm.c (x_check_font): Remove unused local.
17465 * scroll.c (CHECK_BOUNDS):
17466 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17467 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17468 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17469 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17470 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17472 (debug_method_add): Use va_list and vsprintf rather than relying
17473 on undefined behavior with wrong number of arguments.
17474 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17475 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17476 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17477 since we're not interested in debugging glyphs with old libraries.
17478 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17479 GCC 4.6.0's static checking.
17481 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17483 Integer overflow and signedness fixes (Bug#8873).
17484 A few related buffer overrun fixes, too.

17491 (x_create_bitmap_from_data, x_create_bitmap_from_file)
17492 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17493 (x_create_bitmap_from_xpm_data):
17494 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17495 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17497 * xfaces.c (load_pixmap):
17498 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17499 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17500 (.bitmaps_last, struct x_output.icon_bitmap):
17501 Use ptrdiff_t, not int, for bitmap indexes.
17502 (x_allocate_bitmap_record): Check for size overflow.
17503 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17505 Use ptrdiff_t, not int, for overlay counts.
17506 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17507 * editfns.c (overlays_around, get_pos_property):
17508 * textprop.c (get_char_property_and_overlay):
17509 * xdisp.c (next_overlay_change, note_mouse_highlight):
17510 * xfaces.c (face_at_buffer_position):
17511 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17512 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17513 (Fnext_overlay_change, Fprevious_overlay_change)
17514 (mouse_face_overlay_overlaps, Foverlays_in):
17515 Use ptrdiff_t, not int, for sizes.
17516 (overlays_at, overlays_in): Check for size-calculation overflow.
17518 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17520 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17521 (x_session_initialize): Do not assume string length fits in int.
17523 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17524 This is unlikely, but can occur if DPI is outlandish.
17526 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17527 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17529 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17530 * xrdb.c (magic_file_p, search_magic_path):
17531 Omit last arg SUFFIX; it was always 0. All callers changed.
17532 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17534 * xfont.c (xfont_match): Avoid need for strlen.
17536 * xfns.c: Don't assume strlen fits in int.
17537 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17539 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17540 not unsigned long, as we prefer signed integers. All callers changed.
17541 Detect integer overflow in repeat count.
17542 (message_dolog): Don't assume print length fits in 39 bytes.
17543 (display_mode_element): Don't assume strlen fits in int.
17545 * termcap.c: Don't assume sizes fit in int and never overflow.
17546 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17547 (gobble_line): Check for size-calculation overflow.
17549 * minibuf.c (Fread_buffer):
17550 * lread.c (intern, intern_c_string):
17551 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17552 Don't assume string length fits in int.
17554 * keyboard.c (parse_tool_bar_item):
17555 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17557 * font.c: Don't assume string length fits in int.
17558 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17559 Use ptrdiff_t, not int.
17560 (font_intern_prop): Don't assume string length fits in int.
17561 Don't assume integer property fits in fixnum.
17562 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17564 * filelock.c: Fix some buffer overrun and integer overflow issues.
17565 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17566 Reformulate so as not to need the command string.
17567 Invoke gzip -cd rather than gunzip, as it's more portable.
17568 (lock_info_type, lock_file_1, lock_file):
17569 Don't assume pid_t and time_t fit in unsigned long.
17570 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17571 (current_lock_owner): Prefer signed type for sizes.
17572 Use memcpy, not strncpy, where memcpy is what is really wanted.
17573 Don't assume (via atoi) that time_t and pid_t fit in int.
17574 Check for time_t and/or pid_t out of range, e.g., via a network share.
17575 Don't alloca where an auto var works fine.
17577 * fileio.c: Fix some integer overflow issues.
17578 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17579 Don't assume string length fits in int.
17580 (directory_file_name): Don't assume string length fits in long.
17581 (make_temp_name): Don't assume pid fits in int, or that its print
17582 length is less than 20.
17584 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17586 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17588 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17590 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17591 We prefer signed integers, even for size calculations.
17593 * emacs.c: Don't assume string length fits in 'int'.
17594 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17595 (main): Don't invoke strlen when not needed.
17597 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17598 (XD_DEBUG_MESSAGE): Don't waste a byte.
17600 * callproc.c (getenv_internal_1, getenv_internal)
17601 (Fgetenv_internal):
17602 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17604 * lread.c (invalid_syntax): Omit length argument.
17605 All uses changed. This doesn't fix a bug, but it simplifies the
17606 code away from its former Hollerith-constant appearance, and it's
17607 one less 'int' to worry about when looking at integer-overflow issues.
17608 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17610 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17611 This didn't break anything, but it didn't help either.
17612 It's confusing to put a bogus integer in a place where the actual
17613 value does not matter.
17614 (LIST_END_P): Remove unused macro and its bogus comment.
17615 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17617 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17618 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17620 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17621 We prefer signed types, and the value cannot exceed the EMACS_INT
17622 range anyway (because otherwise the length would not be representable).
17623 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17624 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17625 This avoids a GCC warning when WIDE_EMACS_INT.
17627 * indent.c (sane_tab_width): New function.
17628 (current_column, scan_for_column, Findent_to, position_indentation)
17629 (compute_motion): Use it. This is just for clarity.
17630 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17632 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17634 * lisp.h (lint_assume): New macro.
17635 * composite.c (composition_gstring_put_cache):
17636 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17638 * editfns.c, insdel.c:
17639 Omit unnecessary forward decls, to simplify future changes.
17641 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17643 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17645 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17646 Use much-faster test for byte-length change.
17647 Don't assume string byte-length fits in 'int'.
17648 Check that character arg fits in 'int'.
17649 (mapcar1): Declare byte as byte, for clarity.
17651 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17653 * fns.c (concat): Catch string overflow earlier.
17654 Do not rely on integer wraparound.
17656 * dispextern.h (struct it.overlay_strings_charpos)
17657 (struct it.selective): Now EMACS_INT, not int.
17658 * xdisp.c (forward_to_next_line_start)
17659 (back_to_previous_visible_line_start)
17660 (reseat_at_next_visible_line_start, next_element_from_buffer):
17661 Don't arbitrarily truncate the value of 'selective' to int.
17663 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17665 * composite.c: Don't truncate sizes to 'int'.
17666 (composition_gstring_p, composition_reseat_it)
17667 (composition_adjust_point): Use EMACS_INT, not int.
17668 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17669 not EMACS_UINT, for indexes.
17671 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17673 * buffer.c: Include <verify.h>.
17674 (struct sortvec.priority, struct sortstr.priority):
17675 Now EMACS_INT, not int.
17676 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17677 (struct sortstr.size, record_overlay_string)
17678 (struct sortstrlist.size, struct sortlist.used):
17679 Don't truncate size to int.
17680 (record_overlay_string): Check for size-calculation overflow.
17681 (init_buffer_once): Check at compile-time, not run-time.
17683 2011-06-22 Jim Meyering <meyering@redhat.com>
17685 Don't leak an XBM-image-sized buffer
17686 * image.c (xbm_load): Free the image buffer after using it.
17688 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17691 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17692 that Sun C diagnosed.
17693 * fns.c (secure_hash): Fix pointer signedness issue.
17694 * intervals.c (static_offset_intervals): New function.
17695 (offset_intervals): Use it.
17697 2011-06-21 Leo Liu <sdl.web@gmail.com>
17700 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17703 * fns.c (secure_hash): Rename from crypto_hash_function and change
17704 the first arg to accept symbols.
17705 (Fsecure_hash): New primitive.
17706 (syms_of_fns): New symbols.
17708 2011-06-20 Deniz Dogan <deniz@dogan.se>
17710 * process.c (Fset_process_buffer): Clarify return value in
17713 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17715 * dispnew.c (add_window_display_history): Use BVAR.
17717 * xdisp.c (debug_method_add): Use BVAR.
17718 (check_window_end, dump_glyph_matrix, dump_glyph)
17719 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17721 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17724 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17725 check till after the cache is created in init_frame_faces.
17727 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17729 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17731 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17733 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17734 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17735 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17737 Improve buffer-overflow checking (Bug#8873).
17738 * fileio.c (Finsert_file_contents):
17739 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17740 Remove the old (too-loose) buffer overflow checks.
17741 They weren't needed, since make_gap checks for buffer overflow.
17742 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17743 The old code merely checked for Emacs fixnum overflow, and relied
17744 on undefined (wraparound) behavior. The new code avoids undefined
17745 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17747 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17748 Tune. Don't use wider integers than needed. Don't use alloca.
17749 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17751 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17753 * insdel.c, lisp.h (buffer_overflow): New function.
17754 (insert_from_buffer_1, replace_range, replace_range_2):
17755 * insdel.c (make_gap_larger):
17756 * editfns.c (Finsert_char):
17757 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17759 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17761 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17763 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17765 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17766 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17768 * fileio.c: Don't assume EMACS_INT fits in off_t.
17769 (emacs_lseek): New static function.
17770 (Finsert_file_contents, Fwrite_region): Use it.
17771 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17773 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17775 * fns.c: Don't overflow int when computing a list length.
17776 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17777 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17778 truncation on 64-bit hosts. Check for QUIT every
17779 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17780 faster and is responsive enough.
17781 (Flength): Report an error instead of overflowing an integer.
17782 (Fsafe_length): Return a float if the value is not representable
17783 as a fixnum. This shouldn't happen except in contrived situations.
17784 (Fnthcdr, Fsort): Don't assume list length fits in int.
17785 (Fcopy_sequence): Don't assume vector length fits in int.
17787 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17788 (header_size, word_size): New constants.
17789 (allocate_vectorlike): Don't check size overflow here.
17790 (allocate_vector): Check it here instead, since this is the only
17791 caller of allocate_vectorlike that could cause overflow.
17792 Check that the new vector's length is representable as a fixnum.
17794 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17795 The previous code was bogus. For example, next_almost_prime (32)
17796 returned 39, which is undesirable as it is a multiple of 3; and
17797 next_almost_prime (24) returned 25, which is a multiple of 5 so
17798 why was the code bothering to check for multiples of 7?
17800 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17802 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17804 Variadic C functions now count arguments with ptrdiff_t.
17805 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17806 Back then I didn't know that the Emacs coding style prefers signed int.
17807 Also, in the meantime I found a few more instances where arguments
17808 were being counted with int, which may truncate counts on 64-bit
17809 machines, or EMACS_INT, which may be unnecessarily wide.
17810 * lisp.h (struct Lisp_Subr.function.aMANY)
17811 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17812 Arg counts are now ptrdiff_t, not size_t.
17813 All variadic functions and their callers changed accordingly.
17814 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17815 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17816 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17817 * callint.c (Fcall_interactively): Check arg count for overflow,
17818 to avoid potential buffer overrun. Use signed char, not 'int',
17819 for 'varies' array, so that we needn't bother to check its size
17820 calculation for overflow.
17821 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17822 * eval.c (apply_lambda):
17823 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17824 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17825 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17827 * callint.c (Fcall_interactively): Don't use index var as event count.
17829 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17830 * mem-limits.h (SIZE): Remove; no longer used.
17832 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17834 Remove unnecessary casts.
17835 * xterm.c (x_term_init):
17836 * xfns.c (x_set_border_pixel):
17837 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17838 These aren't needed now that we assume ANSI C.
17840 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17841 It's more likely to cause problems (due to unsigned overflow)
17844 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17846 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17848 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17850 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17852 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17854 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17856 GLYPH_CODE_FACE returns EMACS_INT, not int.
17857 * dispextern.h (merge_faces):
17858 * xfaces.c (merge_faces):
17859 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17860 Don't assume EMACS_INT fits in int.
17862 * character.h (CHAR_VALID_P): Remove unused parameter.
17863 * fontset.c, lisp.h, xdisp.c: All uses changed.
17865 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17867 * fns.c (concat): Minor tuning based on overflow analysis.
17868 This doesn't fix any bugs. Use int to hold character, instead
17869 of constantly refetching from Emacs object. Use XFASTINT, not
17870 XINT, for value known to be a character. Don't bother comparing
17871 a single byte to 0400, as it's always less.
17873 * floatfns.c (Fexpt):
17874 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17876 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17879 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17881 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17882 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17883 incorrectly succeed when S was a string, because 4294967386 was
17884 truncated before it was used.
17886 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17887 Otherwise, an out-of-range integer could cause undefined behavior
17890 * composite.c: Use int, not EMACS_INT, for characters.
17891 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17892 EMACS_INT, for values that are known to be in character range.
17893 This doesn't fix any bugs but is the usual style inside Emacs and
17894 may generate better code on 32-bit machines.
17896 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17897 This is for reasons similar to the recent CHAR_STRING fix.
17898 * charset.c (Fencode_char): Check that character arg is actually
17899 a character. Pass an int to ENCODE_CHAR.
17900 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17901 wider than 'int', as a compile-time check to prevent future regressions
17904 * character.c (char_string): Remove unnecessary casts.
17906 Make sure a 64-bit char is never passed to CHAR_STRING.
17907 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17908 by silently ignoring the top 32 bits, allowing some values
17909 that were far too large to be valid characters.
17910 * character.h: Include <verify.h>.
17911 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17912 arguments are no wider than unsigned, as a compile-time check
17913 to prevent future regressions in this area.
17915 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17916 (Fsubst_char_in_region):
17918 * xdisp.c (decode_mode_spec_coding):
17919 Adjust to CHAR_STRING's new requirement.
17920 * editfns.c (Finsert_char, Fsubst_char_in_region):
17921 * fns.c (concat): Check that character args are actually
17922 characters. Without this test, these functions did the wrong
17923 thing with wildly out-of-range values on 64-bit hosts.
17925 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17926 These casts should not be needed on 32-bit hosts, either.
17927 * keyboard.c (read_char):
17928 * lread.c (Fload): Remove casts to unsigned.
17930 * lisp.h (UNSIGNED_CMP): New macro.
17931 This fixes comparison bugs on 64-bit hosts.
17932 (ASCII_CHAR_P): Use it.
17933 * casefiddle.c (casify_object):
17934 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17935 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17936 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17937 * dispextern.h (FACE_FROM_ID):
17938 * keyboard.c (read_char): Use UNSIGNED_CMP.
17940 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17941 not to EMACS_INT, to avoid GCC warning.
17943 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17945 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17946 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17947 isn't needed on 32-bit machines.
17949 * buffer.c (Fgenerate_new_buffer_name):
17950 Use EMACS_INT for count, not int.
17951 (advance_to_char_boundary): Return EMACS_INT, not int.
17953 * data.c (Qcompiled_function): Now static.
17955 * window.c (window_body_lines): Now static.
17957 * image.c (gif_load): Rename local to avoid shadowing.
17959 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17960 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17961 * alloc.c (make_save_value): Integer argument is now of type
17962 ptrdiff_t, not int.
17963 (mark_object): Use ptrdiff_t, not int.
17964 * lisp.h (pD): New macro.
17965 * print.c (print_object): Use it.
17967 * alloc.c: Use EMACS_INT, not int, to count objects.
17968 (total_conses, total_markers, total_symbols, total_vector_size)
17969 (total_free_conses, total_free_markers, total_free_symbols)
17970 (total_free_floats, total_floats, total_free_intervals)
17971 (total_intervals, total_strings, total_free_strings):
17972 Now EMACS_INT, not int. All uses changed.
17973 (Fgarbage_collect): Compute overall total using a double, so that
17974 integer overflow is less likely to be a problem. Check for overflow
17975 when converting back to an integer.
17976 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17977 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17978 These were 'int' variables that could overflow on 64-bit hosts;
17979 they were never used, so remove them instead of repairing them.
17980 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17981 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17982 Previously, this ceilinged at INT_MAX, but that doesn't work on
17984 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17986 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17987 (allocate_vectorlike): Check for ptrdiff_t overflow.
17988 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17989 when a (possibly-narrower) signed value would do just as well.
17990 We prefer using signed arithmetic, to avoid comparison confusion.
17992 * alloc.c: Catch some string size overflows that we were missing.
17993 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17994 for convenience in STRING_BYTES_MAX.
17995 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17996 The definition here is exact; the one in lisp.h was approximate.
17997 (allocate_string_data): Check for string overflow. This catches
17998 some instances we weren't catching before. Also, it catches
17999 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18000 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18001 and ptrdiff_t and EMACS_INT are both 64 bits.
18003 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18004 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18005 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18007 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18009 * alloc.c (Fmake_string): Check for out-of-range init.
18011 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18013 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18015 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18017 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18018 xg_get_default_scrollbar_width.
18020 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.

18028 and height if HAVE_GTK3 (Bug#8505).
18029 (scroll_bar_width_for_theme): New variable.
18030 (update_theme_scrollbar_width): New function.
18031 (xg_get_default_scrollbar_width): Move code to
18032 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18033 (xg_initialize): Call update_theme_scrollbar_width.
18035 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18037 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18039 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18041 * frame.c (make_frame): Call other_buffer_safely instead of
18044 * window.c (temp_output_buffer_show): Call display_buffer with
18045 second argument Vtemp_buffer_show_specifiers and reset latter
18046 immediately after the call.
18047 (Vtemp_buffer_show_specifiers): New variable.
18048 (auto_window_vscroll_p, next_screen_context_lines)
18049 (Vscroll_preserve_screen_position): Remove leading asterisks from

18072 wasn't returning anything.
18073 (compare_window_configurations): Remove unused locals.
18074 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18075 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18076 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers

18232 Remove static from declaration of Qdelete_window, it's
18233 temporarily needed by Fbury_buffer.
18234 (replace_window): Don't assign orig_top_line and

18239 Replace Fdelete_window calls with calls to Qdelete_window.
18240 (Fdelete_other_windows): Remove. Deleting other windows is

18612 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18613 value of a `display' property is a "replacing spec".
18614 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18615 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18645 * gnutls.c: Use Emacs's memory allocators.
18646 Without this change, the gnutls library would invoke malloc etc.
18647 directly, which causes problems on non-SYNC_INPUT hosts, and which
18648 runs afoul of improving memory_full behavior. (Bug#8761)
18649 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18650 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18651 xfree instead of the default malloc, realloc, free.
18652 (Fgnutls_boot): No need to check for memory allocation failure,
18653 since xmalloc does that for us.

18675 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18676 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18677 * alloc.c (allocate_vectorlike):
18678 Check for overflow in vector size calculations.
18679 * ccl.c (ccl_driver):
18680 Check for overflow when converting EMACS_INT to int.
18681 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18682 need to be updated by these changes.
18683 * fns.c (make_hash_table, maybe_resize_hash_table):
18684 Check for integer overflow with large hash tables.
18685 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18686 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18687 (SXHASH_REDUCE): New macro.
18688 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18689 Use it instead of discarding useful hash info with large hash values.
18690 (sxhash_float): New function.
18691 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18692 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18693 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18694 Rewrite to use FIXNUM_BITS, as this simplifies things.
18695 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18696 Adjust signatures to match updated version of code.
18697 (consing_since_gc): Now EMACS_INT, since a single hash table can
18698 use more than INT_MAX bytes.
18700 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18702 Make it possible to build with GCC-4.6+ -O2 -flto.

18706 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18708 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18709 Call minibuffer-inactive-mode.
18711 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18713 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18714 Update dependencies.
18716 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18718 * data.c (init_data): Remove code for UTS, this system is not
18721 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18723 Don't force ./temacs to start in terminal mode.
18725 * frame.c (make_initial_frame): Initialize faces in all cases, not
18726 only when CANNOT_DUMP is defined.
18727 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18729 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18731 * dispnew.c (add_window_display_history): Use const for the string
18732 pointer. Remove declaration, not needed.
18734 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18736 Use 'inline', not 'INLINE'.
18737 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18738 * alloc.c, fontset.c (INLINE): Remove.
18739 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18740 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18741 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18742 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18743 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18745 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18747 Make it possible to run ./temacs.
18749 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18750 syms_of_callproc does the same thing. Remove test for
18751 "initialized", do it in the caller.
18752 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18754 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18756 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18757 (read_minibuf): Use get_minibuffer.
18758 (syms_of_minibuf): Use DEFSYM.
18759 (Qmetadata): New var.
18760 * data.c (Qbuffer): Don't make it static.
18761 (syms_of_data): Use DEFSYM.
18763 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18765 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18766 (CCL_CODE_MIN): New macro.
18768 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18770 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18772 * eval.c (Qdebug): Now static.
18773 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18774 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18775 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18777 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18779 * image.c: Various fixes to ImageMagick code comments.
18780 (Fimagemagick_types): Doc fix.
18782 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18784 Minor fixes prompted by GCC 4.6.0 warnings.
18786 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18788 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18789 (x_clipboard_manager_save_all): Move extern decl to ...
18790 * xterm.h: ... here, so that it can be checked for consistency.
18792 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18794 * xselect.c (x_clipboard_manager_save_frame)
18795 (x_clipboard_manager_save_all): New functions.
18796 (Fx_clipboard_manager_save): Lisp function deleted.
18798 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18799 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18801 * xterm.h: Update prototype.
18803 2011-05-28 William Xu <william.xwl@gmail.com>
18805 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18806 exiting (Bug#8239).
18808 2011-05-28 Jim Meyering <meyering@redhat.com>
18810 Avoid a sign-extension bug in crypto_hash_function.
18811 * fns.c (to_uchar): Define.
18812 (crypto_hash_function): Use it to convert some newly-signed
18813 variables to unsigned, to avoid sign-extension bugs. For example,
18814 without this change, (md5 "truc") would evaluate to
18815 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18816 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18817 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18819 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18821 Integer overflow fixes.
18823 * dbusbind.c: Serial number integer overflow fixes.
18824 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18825 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18826 to hold a serial number that is too large for a fixnum.
18827 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18828 Check for serial numbers out of range. Decode any serial number
18829 that was so large that it became a float. (Bug#8722)
18831 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18832 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18833 Use XFASTINT rather than XUINT when numbers are nonnegative.
18834 (xd_append_arg, Fdbus_method_return_internal):
18835 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18836 arguments, check that Lisp number is nonnegative, rather than
18837 silently wrapping negative numbers around. (Bug#8722)
18838 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18841 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18843 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18845 ccl: Add integer overflow checks.
18846 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18847 (IN_INT_RANGE): New macros.
18848 (ccl_driver): Use them to check for integer overflow when
18849 decoding a CCL program. Many of the new checks are whether XINT (x)
18850 fits in int; it doesn't always, on 64-bit hosts. The new version
18851 doesn't catch all possible integer overflows, but it's an
18852 improvement. (Bug#8719)
18854 * alloc.c (make_event_array): Use XINT, not XUINT.
18855 There's no need for unsigned here.
18857 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18858 This follows up to the 2011-05-06 change that substituted uintptr_t
18859 for EMACS_INT. This case wasn't caught back then.
18861 Rework Fformat to avoid integer overflow issues.
18862 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18863 now (part of C89). Include <verify.h>.
18864 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18865 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18866 (Fformat): Avoid the prepass trying to compute sizes; it was only
18867 approximate and thus did not catch overflow reliably. Instead, walk
18868 through the format just once, formatting and computing sizes as we go,
18869 checking for integer overflow at every step, and allocating a larger
18870 buffer as needed. Keep track separately whether the format is
18871 multibyte. Keep only the most-recently calculated precision, rather
18872 than them all. Record whether each argument has been converted to
18873 string. Use EMACS_INT, not int, for byte and char and arg counts.
18874 Support field widths and precisions larger than INT_MAX. Avoid
18875 sprintf's undefined behavior with conversion specifications such as %#d
18876 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18877 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18878 formatting out-of-range floating point numbers with int
18879 formats. (Bug#8668)
18881 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18883 * data.c: Avoid integer truncation in expressions involving floats.
18884 * data.c: Include <intprops.h>.
18885 (arith_driver): When there's an integer overflow in an expression
18886 involving floating point, convert the integers to floating point
18887 so that the resulting value does not suffer from catastrophic
18888 integer truncation. For example, on a 64-bit host (* 4
18889 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18890 Do not rely on undefined behavior after integer overflow.
18892 merge count_size_as_multibyte, parse_str_to_multibyte
18893 * character.c, character.h (count_size_as_multibyte):
18894 Rename from parse_str_to_multibyte; all uses changed.
18895 Check for integer overflow.
18896 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18897 since it's now a duplicate of the other. This is more of
18898 a character than a buffer op, so better that it's in character.c.
18899 * fns.c, print.c: Adjust to above changes.
18901 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18903 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18905 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18907 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18908 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18909 (x_clipboard_manager_save): Now static.
18910 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18912 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18913 (crypto_hash_function): Now static.
18914 Fix pointer signedness problems. Avoid unnecessary initializations.
18916 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18918 * termhooks.h (Vselection_alist): Make it terminal-local.
18920 * terminal.c (create_terminal): Initialize it.
18922 * xselect.c: Support for clipboard managers.
18923 (Vselection_alist): Move to termhooks.h as terminal-local var.
18924 (LOCAL_SELECTION): New macro.
18925 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18926 (symbol_to_x_atom): Remove gratuitous arg.
18927 (x_handle_selection_request, lisp_data_to_selection_data)
18928 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18929 (x_own_selection, x_get_local_selection, x_convert_selection):
18930 New arg, specifying work frame. Use terminal-local Vselection_alist.
18931 (some_frame_on_display): Delete unused function.
18932 (Fx_own_selection_internal, Fx_get_selection_internal)
18933 (Fx_disown_selection_internal, Fx_selection_owner_p)
18934 (Fx_selection_exists_p): New optional frame arg.
18935 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18936 (x_handle_selection_clear): Don't treat other terminals with the
18937 same keyboard specially. Use the terminal-local Vselection_alist.
18938 (x_clear_frame_selections): Use Frun_hook_with_args.
18940 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18942 * xterm.h: Add support for those atoms.
18944 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18946 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18947 (converted_selections, conversion_fail_tag): New global variables.
18948 (x_selection_request_lisp_error): Free the above.
18949 (x_get_local_selection): Remove unnecessary code.
18950 (x_reply_selection_request): Args changed; handle arbitrary array
18951 of converted selections stored in converted_selections.
18952 Separate the XChangeProperty and SelectionNotify steps.
18953 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18954 (x_convert_selection): New function.
18955 (x_handle_selection_event): Simplify.
18956 (x_get_foreign_selection): Don't ignore incoming requests while
18957 waiting for an answer; this will fail when we implement
18958 SAVE_TARGETS, and seems unnecessary anyway.
18959 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18960 (Vx_sent_selection_functions): Doc fix.
18962 2011-05-26 Leo Liu <sdl.web@gmail.com>
18964 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18966 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18968 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18970 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18971 for fringe update if it has periodic bitmap.
18972 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18973 and fringe_bitmap_periodic_p.
18975 * fringe.c (get_fringe_bitmap_data): New function.
18976 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18977 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18978 row. Mark glyph row for fringe update if periodicity changed.
18980 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18981 for fringe update unless it has periodic bitmap.
18983 2011-05-25 Kenichi Handa <handa@m17n.org>
18985 * xdisp.c (get_next_display_element): Set correct it->face_id for
18986 a static composition.
18988 2011-05-24 Leo Liu <sdl.web@gmail.com>
18991 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18993 * fns.c (crypto_hash_function, Fsha1): New function.
18994 (Fmd5): Use crypto_hash_function.

18997 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18999 * gnutls.c: Remove unused macros.
19000 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19001 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19002 Remove macros that are defined and never used.
19003 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19005 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19007 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19008 (Fx_get_selection_internal): Minor cleanup.
19009 (Fx_own_selection_internal): Rename arguments for consistency with
19012 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19014 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19016 2011-05-22 Chong Yidong <cyd@stupidchicken.com>

19027 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19028 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19029 and add some more files.
19031 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19033 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19034 report_file_error introduced by the change from 2011-05-07.
19036 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19038 * systime.h (Time): Define only if emacs is defined.
19039 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19040 where the include path doesn't have X11/X.h by default. See
19041 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19043 2011-05-20 Kenichi Handa <handa@m17n.org>
19045 * composite.c (find_automatic_composition): Fix previous change.
19047 2011-05-20 Glenn Morris <rgm@gnu.org>
19049 * lisp.mk: New file, split from Makefile.in.
19050 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19051 (shortlisp): Remove.
19052 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19054 2011-05-19 Glenn Morris <rgm@gnu.org>
19056 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19057 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19058 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19059 (lisp): Set the order to that of loadup.el.
19060 (shortlisp): Make it a copy of $lisp.
19061 (SOME_MACHINE_LISP): Remove.
19062 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19063 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19065 2011-05-18 Kenichi Handa <handa@m17n.org>
19067 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19068 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19069 (find_automatic_composition): Mostly rewrite for efficiency.
19071 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19073 * makefile.w32-in: Update dependencies.
19075 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19077 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19078 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19080 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19082 Fix some integer overflow issues, such as string length overflow.
19084 * insdel.c (count_size_as_multibyte): Check for string overflow.
19086 * character.c (lisp_string_width): Check for string overflow.
19087 Use EMACS_INT, not int, for string indexes and lengths; in
19088 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19089 the resulting string length overflows an EMACS_INT; instead,
19090 report a string overflow if no precision given. When checking for
19091 precision exhaustion, use a check that cannot possibly have
19092 integer overflow. (Bug#8675)
19093 * character.h (lisp_string_width): Adjust to new signature.
19095 * alloc.c (string_overflow): New function.
19096 (Fmake_string): Use it. This doesn't change behavior, but saves
19097 a few bytes and will simplify future changes.
19098 * character.c (string_escape_byte8): Likewise.
19099 * lisp.h (string_overflow): New decl.
19101 Fixups, following up to the user-interface timestamp change.
19102 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19103 for UI timestamps, instead of unsigned long.
19104 * msdos.c (mouse_get_pos): Likewise.
19105 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19106 * w32gui.h (Time): Define by including "systime.h" rather than by
19107 declaring it ourselves. (Bug#8664)
19109 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19110 * image.c (clear_image_cache): Likewise.
19112 * term.c (term_mouse_position): Don't assume time_t wraparound.
19114 Be more systematic about user-interface timestamps.
19115 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19116 and sometimes 'EMACS_UINT', to represent these timestamps.
19117 This change causes it to use 'Time' uniformly, as that's what X uses.
19118 This makes the code easier to follow, and makes it easier to catch
19119 integer overflow bugs such as Bug#8664.
19120 * frame.c (Fmouse_position, Fmouse_pixel_position):
19121 Use Time, not unsigned long, for user-interface timestamps.
19122 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19123 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19124 * keyboard.h (last_event_timestamp): Likewise.
19125 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19126 * menu.h (xmenu_show): Likewise.
19127 * term.c (term_mouse_position): Likewise.
19128 * termhooks.h (struct input_event.timestamp): Likewise.
19129 (struct terminal.mouse_position_hook): Likewise.
19130 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19131 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19132 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19133 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19134 what it was before.
19135 * menu.h, termhooks.h: Include "systime.h", for Time.
19137 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19138 Don't assume that the difference between two unsigned long values
19139 can fit into an integer. At this point, we know button_down_time
19140 <= event->timestamp, so the difference must be nonnegative, so
19141 there's no need to cast the result if double-click-time is
19142 nonnegative, as it should be; check that it's nonnegative, just in
19143 case. This bug is triggered when events are more than 2**31 ms
19144 apart (about 25 days). (Bug#8664)
19146 * xselect.c (last_event_timestamp): Remove duplicate decl.
19147 (x_own_selection): Remove needless cast to unsigned long.
19149 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19150 that always fit in int. Use a sentinel instead of a counter, to
19151 avoid a temp and to allay GCC's concerns about possible int overflow.
19152 * frame.h (struct frame): Use int for menu_bar_items_used
19153 instead of EMACS_INT, since it always fits in int.
19155 * menu.c (grow_menu_items): Check for int overflow.
19157 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19159 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19160 Before, the code was not consistent. These values cannot exceed
19161 2**31 - 1 so there's no need to make them unsigned.
19162 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19163 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19164 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19166 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19168 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19169 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19170 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19171 presumably because the widths might not match.
19173 * window.c (size_window): Avoid needless test at loop start.
19175 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19177 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19179 2011-05-12 Drew Adams <drew.adams@oracle.com>
19181 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19183 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19185 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19186 `width' to `bar_area_x' and `bar_area_width', respectively.
19187 (x_scroll_run): Take account of fringe background extension.
19189 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19190 Rename local vars `left' and `width' to `bar_area_x' and
19191 `bar_area_width', respectively.
19192 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19193 background extension.
19195 2011-05-10 Jim Meyering <meyering@redhat.com>
19197 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19199 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19201 * image.c (Finit_image_library): Return t for built-in image types,
19202 like pbm and xbm. (Bug#8640)
19204 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19206 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19208 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19210 * w32console.c (Fset_screen_color): Doc fix.
19211 (Fget_screen_color): New function.
19212 (syms_of_ntterm): Defsubr it.
19214 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19215 unlink the temporary file if Fcall_process didn't create it in the
19217 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19218 child process will be redirected to a file specified with `:file'.
19219 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19220 cue to call_process_cleanup not to close that handle.
19222 2011-05-07 Ben Key <bkey76@gmail.com>
19224 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19225 one of two shell specific rules, either bootstrap-temacs-CMD or
19226 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19227 to the previous implementation of the bootstrap-temacs rule.
19228 The bootstrap-temacs-CMD rule is similar to the previous
19229 implementation of the bootstrap-temacs rule except that it
19230 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19233 These changes, along with some changes to nt/configure.bat,
19234 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19235 earlier fix to add support for --cflags and --ldflags options
19236 that include quotes so that it works whether make uses cmd or
19239 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19241 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19242 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19244 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19245 a string. Handle both cases.
19246 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19247 (Fdbus_register_method): Use Qinvalid_function.
19249 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19251 * makefile.w32-in: Update dependencies.
19252 (LISP_H): Add inttypes.h and stdin.h.
19253 (PROCESS_H): Add unistd.h.
19255 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19257 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19258 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19260 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19262 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19264 * term.c (vfatal): Remove stray call to va_end.
19265 It's not needed and the C Standard doesn't allow it here anyway.
19267 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19268 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19270 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19273 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19275 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19277 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19279 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19281 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19283 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19284 * charset.c (Fdefine_charset_internal): Don't initialize
19285 charset.code_space[15]. The value was garbage, on hosts with
19286 32-bit int (Bug#8600).
19288 * lread.c (read_integer): Be more consistent with string-to-number.
19289 Use string_to_number to do the actual conversion; this avoids
19290 rounding errors and fixes some other screwups. Without this fix,
19291 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19292 (digit_to_number): Move earlier, for benefit of read_integer.
19293 Return -1 if the digit is out of range for the base, -2 if it is
19294 not a digit in any supported base. (Bug#8602)
19296 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19298 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19299 to match comment at start of function. This also removes a
19300 GCC warning about overflow in a 32+64-bit port.
19302 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19304 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19305 Reported by Stefan Monnier in
19306 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19307 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19308 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19310 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19311 (EMACS_UINTPTR): Likewise, with uintptr_t.
19313 * lisp.h: Prefer 64-bit EMACS_INT if available.
19314 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19315 on 32-bit hosts that have 64-bit int, so that they can access
19317 However, temporarily disable this change unless the temporary
19318 symbol WIDE_EMACS_INT is defined.
19320 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19322 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19323 This removes an assumption that EMACS_INT and long are the same
19324 width as pointers. The assumption is true for Emacs porting targets
19325 now, but we want to make other targets possible.
19326 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19327 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19328 In the rest of the code, change types of integers that hold casted
19329 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19330 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19331 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19332 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19333 No need to cast type when ORing.
19334 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19335 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19336 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19337 assume EMACS_INT is the same width as char *.
19338 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19339 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19340 Remove no-longer-needed casts.
19341 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19342 (xg_tool_bar_help_callback, xg_make_tool_item):
19343 Use EMACS_INTPTR to hold an integer
19344 that will be cast to void *; this can avoid a GCC warning
19345 if EMACS_INT is not the same width as void *.
19346 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19347 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19348 (current_message_1, set_message_1):
19349 Use a local to convert to proper width without a cast.
19350 * xmenu.c (dialog_selection_callback): Likewise.
19352 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19353 Also, don't assume VALBITS / RAND_BITS is less than 5,
19354 and don't rely on undefined behavior when shifting a 1 left into
19356 * lisp.h (get_random): Change signature to match.
19358 * lread.c (hash_string): Use size_t, not int, for hash computation.
19359 Normally we prefer signed values; but hashing is special, because
19360 it's better to use unsigned division on hash table sizes so that
19361 the remainder is nonnegative. Also, size_t is the natural width
19362 for hashing into memory. The previous code used 'int', which doesn't
19363 retain enough info to hash well into very large tables.
19364 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19366 * dbusbind.c: Don't possibly lose pointer info when converting.
19367 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19368 Use XPNTR rather than XHASH, so that the high-order bits of
19369 the pointer aren't lost when converting through void *.
19371 * eval.c (Fautoload): Don't double-shift a pointer.
19373 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19375 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19377 * gnutls.c (DEF_GNUTLS_FN):
19378 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19380 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19382 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19385 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19387 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19388 New version that can reserve upto 2GB of heap space.
19390 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19392 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19394 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19396 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19397 `gnutls_certificate_set_x509_key_file'.
19399 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19401 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19402 Update dependencies.
19404 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19406 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19407 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19408 Remove unused parameter `fildes'.
19409 * process.c (read_process_output, send_process): Don't pass it.
19411 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19413 Fix previous change: the library cache is defined in w32.c.
19414 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19415 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19417 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19419 Implement dynamic loading of GnuTLS on Windows.
19421 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19422 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19423 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19426 * gnutls.c (Qgnutls_dll): Define.
19427 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19428 (gnutls_*): Declare function pointers.
19429 (init_gnutls_functions): New function to initialize function pointers.
19430 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19431 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19432 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19433 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19434 (emacs_gnutls_write, emacs_gnutls_read)
19435 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19436 (Fgnutls_available_p): New function.
19437 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19438 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19439 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19441 * image.c: Include w32.h.
19442 (Vimage_type_cache): Delete.
19443 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19444 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19445 (w32_delayed_load): Move to w32.c.
19447 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19449 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19450 (w32_delayed_load): Move from image.c. When loading a library, record
19451 its filename in the :loaded-from property of the library id.
19452 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19453 Initialize and staticpro them.
19454 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19456 * process.c: Include lisp.h before w32.h, not after.
19457 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19458 instead of gnutls_record_check_pending.
19460 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19462 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19464 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19465 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19468 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19470 * xterm.c (x_set_frame_alpha): Do not set property on anything
19471 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19473 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19475 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19477 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19479 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19480 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19486 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19487 (Qgnutls_bootprop_callbacks_verify): Make static.
19489 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19491 * callproc.c: Indentation fixup.
19493 * sysdep.c (wait_for_termination_1): Make static.
19494 (wait_for_termination, interruptible_wait_for_termination):
19495 Move after wait_for_termination_1.
19497 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19499 * sysdep.c (interruptible_wait_for_termination): New function
19500 which is like wait_for_termination, but allows keyboard
19503 * callproc.c (Fcall_process): Add (:file "file") as an option for
19505 (Fcall_process_region): Ditto.
19507 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19509 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19510 rather than `XVECTOR (FOO)->size'.
19512 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19513 inttypes.h, as a gnulib replacement is used if it not available in
19516 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19518 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19519 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19520 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19522 * coding.c (coding_alloc_by_realloc): Error out if destination
19523 will grow beyond MOST_POSITIVE_FIXNUM.
19524 (decode_coding_emacs_mule): Abort if there isn't enough place in
19525 charbuf for the composition carryover bytes. Reserve an extra
19526 space for up to 2 characters produced in a loop.
19527 (decode_coding_iso_2022): Abort if there isn't enough place in
19528 charbuf for the composition carryover bytes.
19530 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19532 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19533 aborting when %lld or %lll format is passed.
19534 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19535 %llo or %llx format is passed. (Bug#8545)
19537 * window.c (window_scroll_line_based): Use a marker instead of
19538 simple variables to record original value of point. (Bug#7952)
19540 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19541 produced by %s or %c overflows available buffer space. (Bug#8545)
19543 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19545 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19546 (SIZE_MAX): Move defn after all includes, as they might #define it.
19548 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19550 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19552 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19554 * keyboard.c (Qdelayed_warnings_hook): Define.
19555 (command_loop_1): Run `delayed-warnings-hook'
19556 if Vdelayed_warnings_list is non-nil.
19557 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19558 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19560 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19562 * doprnt.c (doprnt): Don't return value smaller than the buffer
19563 size if the message was truncated. (Bug#8545).
19565 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19567 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19568 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19570 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19572 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19574 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19576 * makefile.w32-in: Update dependencies.
19578 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19580 Improve `doprnt' and its usage. (Bug#8545)
19581 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19582 `format_end'. Remove support for %l as a conversion specifier.
19583 Don't use xrealloc. Improve diagnostics when the %l size modifier
19584 is used. Update the commentary.
19586 * eval.c (verror): Simplify calculation of size_t.
19588 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19591 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19593 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19596 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19598 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19599 This makes this file independent of the recent pseudovector change.
19601 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19603 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19605 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19606 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19607 Remove unused local.
19608 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19610 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19611 GCC 4.6.0 optimizes based on type-based alias analysis.
19612 For example, if b is of type struct buffer * and v of type struct
19613 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19614 != &v->size, and therefore "v->size = 1; b->size = 2; return
19615 v->size;" must therefore return 1. This assumption is incorrect
19616 for Emacs, since it type-puns struct Lisp_Vector * with many other
19617 types. To fix this problem, this patch adds a new type struct
19618 vectorlike_header that documents the constraints on layout of vectors
19619 and pseudovectors, and helps optimizing compilers not get fooled
19620 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19621 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19622 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19624 (XSETPVECTYPE): Rewrite in terms of new macro.
19625 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19626 This is a bit clearer, and further avoids the possibility of
19627 undesirable aliasing.
19628 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19629 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19630 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19631 since Lisp_Subr is a special case (no "next" field).
19632 (ASIZE): Now uses header.size rather than size.
19633 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19634 to avoid the hassle of writing XVECTOR (foo)->header.size.
19635 (struct vectorlike_header): New type.
19636 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19637 object, to help avoid aliasing.
19638 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19639 (SUBRP): Likewise, since Lisp_Subr is a special case.
19640 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19641 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19642 (struct Lisp_Hash_Table): Combine first two members into a single
19643 struct vectorlike_header member. All uses of "size" and "next" members
19644 changed to be "header.size" and "header.next".
19645 * buffer.h (struct buffer): Likewise.
19646 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19647 * frame.h (struct frame): Likewise.
19648 * process.h (struct Lisp_Process): Likewise.
19649 * termhooks.h (struct terminal): Likewise.
19650 * window.c (struct save_window_data, struct saved_window): Likewise.
19651 * window.h (struct window): Likewise.
19652 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19653 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19654 * buffer.c (init_buffer_once): Likewise.
19655 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19657 * process.c (Fformat_network_address): Use local var for size,
19660 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19662 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19663 * data.c (atof): Remove decl; no longer used or needed.
19664 (digit_to_number): Move to lread.c.
19665 (Fstring_to_number): Use new string_to_number function, to be
19666 consistent with how the Lisp reader treats infinities and NaNs.
19667 Do not assume that floating-point numbers represent EMACS_INT
19668 without losing information; this is not true on most 64-bit hosts.
19669 Avoid double-rounding errors, by insisting on integers when
19670 parsing non-base-10 numbers, as the documentation specifies.
19671 * lisp.h (string_to_number): New decl, replacing ...
19672 (isfloat_string): Remove.
19673 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19674 (read1): Do not accept +. and -. as integers; this
19675 appears to have been a coding error. Similarly, do not accept
19676 strings like +-1e0 as floating point numbers. Do not report
19677 overflow for integer overflows unless the base is not 10 which
19678 means we have no simple and reliable way to continue.
19679 Break out the floating-point parsing into a new
19680 function string_to_number, so that Fstring_to_number parses
19681 floating point numbers consistently with the Lisp reader.
19682 (digit_to_number): Move here from data.c. Make it static inline.
19683 (E_CHAR, EXP_INT): Remove, replacing with ...
19684 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19685 (string_to_number): New function, replacing isfloat_string.
19686 This function checks for valid syntax and produces the resulting
19687 Lisp float number too. Rework it so that string-to-number
19688 no longer mishandles examples like "1.0e+". Use strtoumax,
19689 so that overflow for non-base-10 numbers is reported only when
19690 there's no portable and simple way to convert to floating point.
19692 * textprop.c (set_text_properties_1): Rewrite for clarity,
19693 and to avoid GCC warning about integer overflow.
19695 * intervals.h (struct interval): Use EMACS_INT for members
19696 where EMACS_UINT might cause problems. See
19697 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19698 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19699 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19701 (offset_intervals): Tell GCC not to worry about length overflow
19702 when negating a negative length.
19704 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19705 (overrun_check_free): Likewise.
19707 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19708 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19711 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19712 (gnutls_make_error): Rename local to avoid shadowing.
19713 (gnutls_emacs_global_deinit): ifdef out; not used.
19714 (Fgnutls_boot): Use const for pointer to readonly storage.
19715 Comment out unused local. Fix pointer signedness problems.
19717 * lread.c (openp): Don't stuff size_t into an 'int'.
19718 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19719 about possible signed overflow.
19721 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19722 (GDK_KEY_g): Don't define if already defined.
19723 (xg_prepare_tooltip): Avoid pointer signedness problem.
19724 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19726 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19727 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19729 * xfns.c (Fx_window_property): Simplify a bit,
19730 to make a bit faster and to avoid GCC 4.6.0 warning.
19731 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19733 * fns.c (internal_equal): Don't assume size_t fits in int.
19735 * alloc.c (compact_small_strings): Tighten assertion a little.
19737 Replace pEd with more-general pI, and fix some printf arg casts.
19738 * lisp.h (pI): New macro, generalizing old pEd macro to other
19739 conversion specifiers. For example, use "...%"pI"d..." rather
19740 than "...%"pEd"...".
19741 (pEd): Remove. All uses replaced with similar uses of pI.
19742 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19743 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19744 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19745 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19746 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19747 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19748 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19750 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19751 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19752 * print.c (safe_debug_print, print_object): Likewise.
19753 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19755 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19756 avoiding the 0 flag, which is not portable.
19757 * process.c (Fmake_network_process): Use pI to avoid cast.
19758 * region-cache.c (pp_cache): Likewise.
19759 * xdisp.c (decode_mode_spec): Likewise.
19760 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19761 behavior on 64-bit hosts with printf arg.
19762 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19763 (x_stop_queuing_selection_requests): Likewise.
19764 (x_get_window_property): Don't truncate byte count to an 'int'
19767 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19768 here, since it parses constructs like leading '-' and spaces,
19769 which are not wanted; and it overflows with large numbers.
19770 Instead, simply match F[0-9]+, which is what is wanted anyway.
19772 * alloc.c: Remove unportable assumptions about struct layout.
19773 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19774 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19775 (allocate_vectorlike, make_pure_vector): Use the new macros,
19776 plus offsetof, to remove unportable assumptions about struct layout.
19777 These assumptions hold on all porting targets that I know of, but
19778 they are not guaranteed, they're easy to remove, and removing them
19779 makes further changes easier.
19781 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19782 This doesn't fix a bug but makes the code clearer.
19783 (string_overrun_cookie): Now const. Use initializers that
19784 don't formally overflow signed char, to avoid warnings.
19785 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19786 can cause Emacs to crash when string overrun checking is enabled.
19787 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19788 multiple of sizeof (EMACS_INT); it need not be, if
19789 alignof(EMACS_INT) < sizeof (EMACS_INT).
19790 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19792 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19796 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19798 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19799 supposed to be handshaking. (Bug#8556)
19800 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19802 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19804 * lisp.h (Qdebug): List symbol.
19805 * eval.c (Qdebug): Restore global linkage.

19807 (handle_user_signal): Break into debugger when debug-on-event
19808 matches the current signal symbol.
19810 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19812 * alloc.c (check_sblock, check_string_bytes)
19813 (check_string_free_list): Convert to standard C.
19815 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19817 * w32.c (emacs_gnutls_push): Fix typo.
19819 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19821 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19822 "cast to pointer from integer of different size".
19824 Improve doprnt and its use in verror. (Bug#8545)
19825 * doprnt.c (doprnt): Document the set of format control sequences
19826 supported by the function. Use SAFE_ALLOCA instead of always
19829 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19830 is one byte too soon. Don't use xrealloc; instead xfree and
19833 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19835 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19838 * gnutls.c: Renamed global_initialized to
19839 gnutls_global_initialized. Added internals for the
19840 :verify-hostname-error, :verify-error, and :verify-flags
19841 parameters of `gnutls-boot' and documented those parameters in the
19842 docstring. Start callback support.
19843 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19844 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19845 on error. Return error code.
19846 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19847 (emacs_gnutls_read): Likewise.
19848 (Fgnutls_boot): Return handshake error code.
19849 (emacs_gnutls_handle_error): New function.
19850 (wsaerror_to_errno): Likewise.

19905 changes in globals.h immediately force recompilation.
19906 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19907 $(CURDIR)/s/ms-w32.h.
19908 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

19912 <char-direction-table>: Deleted.
19914 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19916 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19917 * doprnt.c: Include limits.h.
19918 (SIZE_MAX): New macro.
19919 (doprnt): Return a size_t value. 2nd arg is now size_t.
19920 Many local variables are now size_t instead of int or unsigned.
19921 Improve overflow protection. Support `l' modifier for integer
19922 conversions. Support %l conversion. Don't assume an EMACS_INT
19923 argument for integer conversions and for %c.
19925 * lisp.h (doprnt): Restore prototype.
19927 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19928 $(SRC)/character.h.
19930 * Makefile.in (base_obj): Add back doprnt.o.
19932 * deps.mk (doprnt.o): Add back prerequisites.
19933 (callint.o): Depend on character.h.
19935 * eval.c (internal_lisp_condition_case): Include the handler
19936 representation in the error message.
19937 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19938 when breaking from the loop.
19940 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19942 * callint.c (Fcall_interactively): When displaying error message
19943 about invalid control letter, pass the character's codepoint, not
19944 a pointer to its multibyte form. Improve display of the character
19945 in octal and display also its hex code.
19947 * character.c (char_string): Use %x to display the (unsigned)
19948 codepoint of an invalid character, to avoid displaying a bogus
19951 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19952 `error', not SYMBOL_NAME itself.
19954 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19955 character arguments to `error'.
19957 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19958 to `error' in error message about FINAL_CHAR argument. Make sure
19959 FINAL_CHAR is a character, and use %c when it is passed as
19960 argument to `error'.
19962 2011-04-23 Eli Zaretskii <eliz@gnu.org>

20150 ns_descriptor_to_entity that were caused by using free to
20151 deallocate memory blocks that were allocated by xmalloc (via
20152 xstrdup). This caused Emacs to crash when compiled with

20173 * process.c (send_process): Adjust to the new signatures of
20174 emacs_write and emacs_gnutls_write. Do not attempt to store

20510 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20511 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20512 exported only to the debugger.
20514 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20515 * atimer.h (run_all_atimers): Remove; not exported.
20517 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20518 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20519 was inaccessible from Lisp.
20520 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20521 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20523 alloc.c: Import and export fewer symbols, and remove unused items.
20524 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20526 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20527 it's not optimized away by whole-program optimization.

20539 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20540 (mark_backtrace): Define only if BYTE_MARK_STACK.
20541 * xdisp.c (message_enable_multibyte): Now static.
20543 Declare Lisp_Object Q* variables to be 'static' if not exported.
20544 This makes it easier for human readers (and static analyzers)
20545 to see whether these variables are used from other modules.
20546 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

20556 Remove decls of unexported vars.
20557 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20559 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20561 Make Emacs functions such as Fatom 'static' by default.
20562 This makes it easier for human readers (and static analyzers)
20563 to see whether these functions can be called from other modules.
20564 DEFUN now defines a static function. To make the function external
20565 so that it can be used in other C modules, use the new macro DEFUE.
20566 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20567 (Finit_image_library):
20568 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

20570 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20571 Remove decls, since these functions are now static.
20572 (Funintern, Fget_internal_run_time): New decls, since these functions
20573 were already external.
20575 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20583 Mark functions with DEFUE instead of DEFUN,
20584 if they are used in other modules.
20585 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20586 decls for now-static functions.
20587 * buffer.h (Fdelete_overlay): Remove decl.

20597 * image.c (Finit_image_library): New forward static decl.
20598 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20599 * intervals.h (Fprevious_property_change):
20600 (Fremove_list_of_text_properties): Remove decls.
20601 * keyboard.c (Fthis_command_keys): Remove decl.
20602 (Fcommand_execute): New forward static decl.

20623 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20625 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20626 when at ZV. (Bug#8487)
20628 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20630 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20633 * sound.c (sound_cleanup, alsa_close): Likewise.
20634 * termcap.c (tgetent): Likewise.

20636 * xsettings.c (read_and_apply_settings): Likewise.
20638 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20639 (overrun_check_free): Protoize.
20641 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20643 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20644 since callers should never pass a negative size.
20645 Change the signature to match that of plain 'read' and 'write'; see
20646 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20647 * lisp.h: Update prototypes of emacs_write and emacs_read.
20649 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20651 * xdisp.c (redisplay_window): Don't try to determine the character
20652 position of the scroll margin if the window start point w->startp
20653 is outside the buffer's accessible region. (Bug#8468)
20655 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20657 Fix write-region and its subroutines for buffers > 2GB.
20658 * fileio.c (a_write, e_write): Modify declaration of arguments and
20659 local variables to support buffers larger than 2GB.
20660 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20662 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20663 argument, local variables, and return value.
20665 * lisp.h: Update prototypes of emacs_write and emacs_read.
20667 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20669 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20671 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20673 Fix more problems found by GCC 4.6.0's static checks.
20675 * xdisp.c (vmessage): Use a better test for character truncation.
20677 * charset.c (load_charset_map): <, not <=, for optimization,
20678 and to avoid potential problems with integer overflow.
20679 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20680 * casetab.c (set_identity, shuffle): Likewise.
20681 * editfns.c (Fformat): Likewise.
20682 * syntax.c (skip_chars): Likewise.
20684 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20685 This also lets GCC 4.6.0 generate slightly better loop code.
20687 * callint.c (Fcall_interactively): <, not <=, for optimization.
20688 (Fcall_interactively): Count the number of arguments produced,
20689 not the number of arguments given. This is simpler and lets GCC
20690 4.6.0 generate slightly better code.
20692 * ftfont.c: Distingish more carefully between FcChar8 and char.
20693 The previous code passed unsigned char * to a functions like
20694 strlen and xstrcasecmp that expect char *, which does not
20695 conform to the C standard.
20696 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20697 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20698 char * when the C standard requires it.
20700 * keyboard.c (read_char): Remove unused var.
20702 * eval.c: Port to Windows vsnprintf (Bug#8435).
20703 Include <limits.h>.
20704 (SIZE_MAX): Define if the headers do not.
20705 (verror): Do not give up if vsnprintf returns a negative count.
20706 Instead, grow the buffer. This ports to Windows vsnprintf, which
20707 does not conform to C99. Problem reported by Eli Zaretskii.
20708 Also, simplify the allocation scheme, by avoiding the need for
20709 calling realloc, and removing the ALLOCATED variable.
20711 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20713 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20714 But keep the doprint source code for now, as we might revamp it
20715 and use it again (Bug#8435).
20716 * lisp.h (doprnt): Remove.
20717 * Makefile.in (base_obj): Remove doprnt.o.
20718 * deps.mk (doprnt.o): Remove.
20720 error: Print 32- and 64-bit integers portably (Bug#8435).
20721 Without this change, on typical 64-bit hosts error ("...%d...", N)
20722 was used to print both 32- and 64-bit integers N, which relied on
20723 undefined behavior.
20724 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20725 * lisp.h (error, verror): Mark as printf-like functions.
20726 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20727 Report overflow in size calculations when allocating printf buffer.
20728 Do not truncate output string at its first null byte.
20729 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20730 Truncate the output at a character boundary, since vsnprintf does not
20732 * charset.c (check_iso_charset_parameter): Convert internal
20733 character to string before calling 'error', since %c now has the
20735 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20736 overflow when computing char to be passed to 'error'. Do not
20737 pass Lisp_Object to 'error'; pass the integer instead.
20738 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20739 formatted with plain %d.
20741 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20743 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20745 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20747 * xterm.c (x_catch_errors): Remove duplicate declaration.
20749 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20751 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20753 2011-04-10 Jim Meyering <meyering@redhat.com>
20755 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20756 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20757 return ssize_t not "int", and use size_t as the buffer length.
20758 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20759 * gnutls.h: Update declarations.
20760 * process.c (read_process_output): Use ssize_t, to match.
20761 (send_process): Likewise.
20763 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20765 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20767 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20769 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20770 Use unsigned char, to match FcChar8 type definition.
20772 * xterm.c (handle_one_xevent):
20773 * xmenu.c (create_and_show_popup_menu):
20774 * xselect.c (x_decline_selection_request)
20775 (x_reply_selection_request): Avoid type-punned deref of X events.
20777 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20779 Fix some uses of `int' instead of EMACS_INT.
20780 * search.c (string_match_1, fast_string_match)
20781 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20782 (scan_buffer, find_next_newline_no_quit)
20783 (find_before_next_newline, search_command, Freplace_match)
20784 (Fmatch_data): Make some `int' variables be EMACS_INT.
20786 * xdisp.c (display_count_lines): 3rd argument and return value now
20787 EMACS_INT. All callers changed.
20788 (pint2hrstr): Last argument is now EMACS_INT.
20790 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20791 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20792 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20803 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20804 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20806 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20807 (encode_invocation_designation): Last argument P_NCHARS is now
20809 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20810 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20812 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20815 * ccl.c (Fccl_execute_on_string): Declare some variables
20818 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20820 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20822 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20824 * process.c (Fformat_network_address): Doc fix.
20826 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20828 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20830 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20832 * keyboard.c (read_char): Call Lisp function help-form-show,
20833 instead of using internal_with_output_to_temp_buffer.
20834 (Qhelp_form_show): New var.
20835 (syms_of_keyboard): Use DEFSYM macro.
20837 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20844 (list_processes_1): Delete.
20846 2011-04-06 Eli Zaretskii <eliz@gnu.org>

20850 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20852 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20854 Fix more problems found by GCC 4.6.0's static checks.
20856 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20858 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20860 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20862 * xdisp.c (vmessage): Mark as a printf-like function.
20864 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20868 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20869 printf-like functions.
20870 (tiff_load): Add casts to remove these marks before passing them
20871 to system-supplied API.
20873 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20875 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20876 This avoids several warnings with gcc -Wstrict-overflow.
20877 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20878 directly, rather than having caller test rule sign. This avoids
20879 some unnecessary tests.
20880 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20881 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20882 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20884 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20885 (xfont_open): Avoid unnecessary tests.
20887 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20889 * composite.h, composite.c (composition_gstring_put_cache):
20890 Use EMACS_INT, not int, for length.
20892 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20893 breaking out part of COMPOSITION_DECODE_RULE.
20894 (COMPOSITION_DECODE_RULE): Use it.
20895 * composite.c (get_composition_id): Remove unused local vars,
20896 by using the new macro.
20898 * textprop.c (set_text_properties_1): Change while to do-while,
20899 since the condition is always true at first.
20901 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20902 (interval_deletion_adjustment): Return unsigned value.
20905 * process.c (list_processes_1, create_pty, read_process_output):
20906 (exec_sentinel): Remove vars that were set but not used.
20907 (create_pty): Remove unnecessary "volatile"s.
20908 (Fnetwork_interface_info): Avoid possibility of int overflow.
20909 (read_process_output): Do adaptive read buffering even if carryover.
20910 (read_process_output): Simplify nbytes computation if buffered.
20912 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
20914 * syntax.c (scan_words): Remove var that was set but not used.
20915 (update_syntax_table): Use unsigned instead of int.
20917 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20918 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20919 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20921 * print.c (print_error_message): Avoid int overflow.
20923 * font.c (font_list_entities): Redo for clarity,
20924 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20926 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20927 (font_score): Avoid potential overflow in diff calculation.
20929 * fns.c (substring_both): Remove var that is set but not used.
20930 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20932 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20934 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20935 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20936 can always succeed if overflow has undefined behavior.
20938 * search.c (boyer_moore, wordify): Remove vars set but not used.
20939 (wordify): Omit three unnecessary tests.
20941 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20942 All callers changed. This avoids the need for an unused var.
20944 * casefiddle.c (casify_region): Remove var that is set but not used.
20946 * dired.c (file_name_completion): Remove var that is set but not used.
20948 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20950 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20951 (Finsert_file_contents): Remove unnecessary code checking fd.
20953 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20954 Check for integer overflow on size calculations.
20956 * buffer.c (Fprevious_overlay_change): Remove var that is set
20959 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20960 Remove vars that are set but not used.
20961 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20962 (timer_check_2): Mark vars as initialized.
20964 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20966 * image.c (lookup_image): Remove var that is set but not used.
20967 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20969 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20970 that are set but not used.
20972 * xfns.c (make_invisible_cursor): Don't return garbage
20973 if XCreateBitmapFromData fails (Bug#8410).
20975 * xselect.c (x_get_local_selection, x_handle_property_notify):
20976 Remove vars that are set but not used.
20978 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20979 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20981 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20982 Remove var that is set but not used.
20983 (scroll_bar_windows_size): Now size_t, not int.
20984 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20985 Check for overflow.
20987 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20988 (map_tty_color) [!defined MSDOS]: Likewise.
20990 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20992 * coding.c: Remove vars that are set but not used.
20993 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20994 All callers changed.
20995 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20996 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20997 (decode_coding_charset): Remove vars that are set but not used.
20999 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21000 that is set but not used.
21002 * print.c (print_object): Remove var that is set but not used.
21004 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21005 The gnulib version avoids calling malloc in the usual case,
21006 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21007 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21008 * filelock.c (current_lock_owner): Likewise.
21009 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21010 * sysdep.c: Include allocator.h, careadlinkat.h.
21011 (emacs_no_realloc_allocator): New static constant.
21012 (emacs_readlink): New function.
21013 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21014 ../lib/careadlinkat.h.
21016 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21018 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21019 first non-nil return value).
21021 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21023 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21024 if not defined (Bug#8403).
21026 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21028 * xdisp.c (display_count_lines): Remove parameter `start',
21029 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21030 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21031 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21033 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21034 and thereabouts. All callers changed.
21035 (get_per_char_metric): Remove parameter `f', unused since
21036 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21038 2011-04-02 Jim Meyering <meyering@redhat.com>
21040 do not dereference NULL upon failed strdup
21041 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21042 (ns_get_family): Likewise.
21044 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21046 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21048 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21050 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21053 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21055 Add lexical binding.
21057 * window.c (Ftemp_output_buffer_show): New fun.
21058 (Fsave_window_excursion):
21059 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21061 * lread.c (lisp_file_lexically_bound_p): New function.
21062 (Fload): Bind Qlexical_binding.
21063 (readevalloop): Remove `evalfun' arg.
21064 Bind Qinternal_interpreter_environment.
21065 (Feval_buffer): Bind Qlexical_binding.
21066 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21068 (syms_of_lread): Declare `lexical-binding'.
21070 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21072 * keyboard.c (eval_dyn): New fun.
21073 (menu_item_eval_property): Use it.
21075 * image.c (parse_image_spec): Use Ffunctionp.
21077 * fns.c (concat, mapcar1): Accept byte-code-functions.
21079 * eval.c (Fsetq): Handle lexical vars.
21080 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21081 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21082 (FletX, Flet): Obey lexical binding.
21083 (Fcommandp): Handle closures.
21084 (Feval): New `lexical' arg.
21085 (eval_sub): New function extracted from Feval. Use it almost
21086 everywhere where Feval was used. Look up vars in lexical env.
21088 (Ffunctionp): Move from subr.el.
21089 (Ffuncall): Handle closures.
21090 (apply_lambda): Remove `eval_flags'.
21091 (funcall_lambda): Handle closures and new byte-code-functions.
21092 (Fspecial_variable_p): New function.
21093 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21094 but without exporting it to Lisp.
21096 * doc.c (Fdocumentation, store_function_docstring):
21097 * data.c (Finteractive_form): Handle closures.
21099 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21102 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21104 (exec_byte_code): New function extracted from Fbyte_code to handle new
21105 calling convention for byte-code-functions. Add new byte-codes.
21107 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21109 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21111 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21113 * xdisp.c (redisplay_internal): Fix prototype.
21115 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21117 * xdisp.c (SCROLL_LIMIT): New macro.
21118 (try_scrolling): Use it when setting scroll_limit.
21119 Limit scrolling to 100 screen lines.
21120 (redisplay_window): Even when falling back on "recentering",
21121 position point in the window according to scroll-conservatively,
21122 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21124 (try_scrolling): When point is above the window, allow searching
21125 as far as scroll_max, or one screenful, to compute vertical
21126 distance from PT to the scroll margin position. This prevents
21127 try_scrolling from unnecessarily failing when
21128 scroll-conservatively is set to a value slightly larger than the
21129 window height. Clean up the case of PT below the margin at bottom
21130 of window: scroll_max can no longer be INT_MAX. When aggressive
21131 scrolling is in use, don't let point enter the opposite scroll
21132 margin as result of the scroll.
21133 (syms_of_xdisp) <scroll-conservatively>: Document the
21134 threshold of 100 lines for never-recentering scrolling.
21136 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21138 * dispextern.h (move_it_by_lines):
21139 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

21141 (message_log_check_duplicate): Remove parameters `prev_bol' and
21142 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21143 (redisplay_internal): Remove parameter `preserve_echo_area',
21144 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21146 * indent.c (Fvertical_motion):
21147 * window.c (window_scroll_pixel_based, Frecenter):
21148 Don't pass `need_y_p' to `move_it_by_lines'.
21150 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21152 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21153 steal a few bits to be more compact.
21154 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21155 Remove unneeded casts.
21157 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21159 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21161 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21162 binding" message (bug#7967).
21164 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21166 Fix more problems found by GCC 4.6.0's static checks.
21168 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21169 Remove unused local var.
21171 * editfns.c (Fmessage_box): Remove unused local var.
21173 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21174 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21175 Omit unused local vars.
21176 * window.c (shrink_windows): Omit unused local var.
21177 * menu.c (digest_single_submenu): Omit unused local var.
21178 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21179 Omit unused local var.
21181 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21182 Don't assume string length fits in int.
21183 (keyremap_step, read_key_sequence): Use size_t for sizes.
21184 (read_key_sequence): Don't check last_real_key_start redundantly.
21186 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21187 instead of alloca (Bug#8344).
21189 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21190 (Fbacktrace_frame): Don't assume nframes fits in int.
21192 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21194 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21197 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21199 * cm.c (calccost): Turn while-do into do-while, for clarity.
21201 * keyboard.c (syms_of_keyboard): Use the same style as later
21202 in this function when indexing through an array. This also
21203 works around GCC bug 48267.
21205 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21207 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21209 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21210 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21212 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21213 This avoids undefined behavior on integer overflow, and is a bit
21214 more convenient anyway since it is compared to a size_t variable.
21216 Variadic C functions now count arguments with size_t, not int.
21217 This avoids an unnecessary limitation on 64-bit machines, which
21218 caused (substring ...) to crash on large vectors (Bug#8344).
21219 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21220 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21228 * fns.c (concat): Likewise.
21229 * frame.c (x_set_frame_parameters): Likewise.
21230 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21231 0 if not found, not -1. All callers changed.
21233 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21234 (stack_copy_size): Now size_t, not int.
21235 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21237 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21239 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21240 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21241 All callers changed.
21243 * lisp.h (multibyte_char_to_unibyte):
21244 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21245 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21249 * keymap.c (push_key_description):
21250 * search.c (Freplace_match):
21251 * xdisp.c (message_dolog, set_message_1): All callers changed.
21253 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21255 * keyboard.c (safe_run_hook_funcall): New function.
21256 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21257 don't set the hook to nil, but remove the offending function instead.
21258 (Qcommand_hook_internal): Remove, unused.
21259 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21260 Vcommand_hook_internal.
21262 * eval.c (enum run_hooks_condition): Remove.
21263 (funcall_nil, funcall_not): New functions.
21264 (run_hook_with_args): Call each function through a `funcall' argument.
21265 Remove `cond' argument, now redundant.
21266 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21267 (Frun_hook_with_args_until_failure): Adjust accordingly.
21268 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

21274 * print.c (strout): Remove parameter `multibyte', unused since
21275 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21277 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21278 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21279 All callers changed.
21281 * w32.c (_wsa_errlist): Use braces for struct initializers.
21283 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21284 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21285 All callers changed.

21440 * buffer.c (Fkill_all_local_variables):
21441 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21443 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21444 unconditionally since it does the check itself.
21446 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21448 Fix more problems found by GCC 4.5.2's static checks.
21450 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21451 the first time through the loop, since we know p0 < p1 then.
21452 This also avoids a gcc -Wstrict-overflow warning.
21454 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21455 leading to a memory leak, possible in functions like
21456 load_charset_map_from_file that can allocate an unbounded number
21457 of objects (Bug#8318).
21459 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21460 that could (at least in theory) be that large.
21462 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21463 This is less likely to overflow, and avoids undefined behavior if
21464 overflow does occur. All callers changed. Use strtoul to scan
21465 for the unsigned long integer.
21466 (pint2hrstr): Simplify and tune code slightly.
21467 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21477 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21480 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21482 * process.c (Fmake_network_process): Use socklen_t, not int,
21483 where POSIX says socklen_t is required in portable programs.
21484 This fixes a porting bug on hosts like 64-bit HP-UX, where
21485 socklen_t is wider than int (Bug#8277).
21486 (Fmake_network_process, server_accept_connection):
21487 (wait_reading_process_output, read_process_output):
21490 * process.c: Rename or move locals to avoid shadowing.

21500 Make tparam.h and terminfo.c consistent.
21501 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21502 Include tparam.h instead, since it declares them.
21503 * cm.h (PC): Remove extern decl; tparam.h now does this.
21504 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21505 * terminfo.c: Include tparam.h, to check interfaces.
21506 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21507 (tparam): Adjust signature to match interface in tparam.h;
21508 this removes some undefined behavior. Check that outstring and len
21509 are zero, which they always are with Emacs.
21510 * tparam.h (PC, BC, UP): New extern decls.
21512 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21513 (xftfont_open): Rename locals to avoid shadowing.

21527 * composite.c (composition_compute_stop_pos): Rename local to
21529 (composition_reseat_it): Remove unused locals.
21530 (find_automatic_composition, composition_adjust_point): Likewise.
21531 (composition_update_it): Mark var as initialized.
21532 (find_automatic_composition): Mark vars as initialized,
21533 with a FIXME (Bug#8290).

21537 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21538 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21539 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21540 to avoid shadowing.
21542 * textprop.c (property_change_between_p): Remove; unused.
21544 * intervals.c (interval_start_pos): Now static.
21546 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21552 Fix pointer signedness.
21553 (alsa_choose_format): Remove unused local var.
21554 (wav_play): Initialize a variable to 0, to prevent undefined
21555 behavior (Bug#8278).
21557 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21559 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21561 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21562 clobbering (Bug#8298).
21563 * sysdep.c (sys_subshell): Likewise.
21564 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21566 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21567 This should get cleaned up, so that child_setup has the
21568 same signature on all platforms.
21570 * callproc.c (call_process_cleanup): Now static.
21571 (relocate_fd): Rename locals to avoid shadowing.
21573 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21575 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21576 not to be necessary, and produces flickering.
21578 2011-03-20 Glenn Morris <rgm@gnu.org>
21580 * config.in: Remove file.
21582 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21584 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21585 are now in src/globals.h.
21586 (syms_of_minibuf): Remove spurious & from previous change.

21626 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
21627 Define only if needed.
21629 * unexelf.c (unexec): Name an expression,
21630 to avoid gcc -Wbad-function-cast warning.
21631 Use a different way to cause a compilation error if anyone uses
21632 n rather than nn, a way that does not involve shadowing.
21633 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21635 * deps.mk (unexalpha.o): Remove; unused.
21637 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21712 ENABLE_CHECKING is not defined.
21714 * data.c (Findirect_variable): Name an expression, to avoid
21715 gcc -Wbad-function-cast warning.

21756 which gcc can warn about.
21757 (regex_compile, re_match_2_internal): Mark locals as initialized.
21758 (RETALLOC_IF): Define only if needed.
21759 (WORDCHAR_P): Likewise. This one is never needed, but is used
21760 only in a comment talking about a compiler bug, so put inside
21761 the #if 0 of that comment.
21762 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21763 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21766 * search.c (boyer_moore): Rename locals to avoid shadowing.

21791 gcpro1, gcpro2, etc.
21792 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21794 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21795 argument, for consistency with GCPRO2_VAR, etc: it is now the

21799 Rename locals to avoid shadowing.
21801 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21802 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21803 dired.c's scmp function, had undefined behavior.

21805 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21806 * buffer.h: ... to here, because these macros use current_buffer,
21807 and the new implementation with inline functions needs to have
21808 current_buffer in scope now, rather than later when the macros
21810 (downcase, upcase1): New static inline functions.
21811 (DOWNCASE, UPCASE1): Reimplement using these functions.
21812 This avoids undefined behavior in expressions like
21813 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21814 from race conditions in accessing the global variables
21815 case_temp1 and case_temp2.
21816 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

21827 (file_name_as_directory): Use const pointers when appropriate.
21828 (Fexpand_file_name): Likewise. In particular, newdir might
21829 point at constant storage, so make it a const pointer.

21833 (Fset_file_times, Finsert_file_contents, auto_save_error):

21840 * marker.c (bytepos_to_charpos): Remove; unused.
21842 * lisp.h (verify_bytepos, count_markers): New decls,
21843 so that gcc does not warn that these functions aren't declared.

21846 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21847 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21848 (copy_text): Remove unused local var.

21851 (lock_file_1): Rename local to avoid shadowing.
21853 * buffer.c (fix_overlays_before): Mark locals as initialized.
21854 (fix_start_end_in_overlays): Likewise. This function should be
21855 simplified by using pointers-to-pointers, but that's a different
21857 (switch_to_buffer_1): Now static.
21858 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21859 (report_overlay_modification): Rename locals to avoid shadowing.

21862 Fix pointer signedness issue.
21863 (sys_subshell): Mark local as volatile if checking for lint,
21864 to suppress a gcc -Wclobbered warning that does not seem to be right.
21865 (MAXPATHLEN): Define only if needed.
21867 * process.c (serial_open, serial_configure): Move decls from here ...
21868 * systty.h: ... to here, so that they can be checked.
21870 * fns.c (get_random, seed_random): Move extern decls from here ...
21871 * lisp.h: ... to here, so that they can be checked.
21873 * sysdep.c (reset_io): Now static.
21874 (wait_for_termination_signal): Remove; unused.
21876 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21882 (describe_map_tree):
21883 Rename locals to avoid shadowing.
