5 (Fcommand_execute): Remove, replace by an Elisp implementation.
6 (syms_of_keyboard): Adjust accordingly.
8 2013-02-19 Daniel Colascione <dancol@dancol.org>
10 * sheap.c (report_sheap_usage): Use message, not message1, so
11 that we don't try to create a buffer while we're in the middle
12 of dumping Emacs. Explain why.
14 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
15 * search.c (find_newline): Return byte position in bytepos.
17 (find_next_newline_no_quit, find_before_next_newline):
19 * lisp.h (find_newline, find_next_newline_no_quit)

21 * bidi.c (bidi_find_paragraph_start):
22 * editfns.c (Fconstrain_to_field, Fline_end_position):
23 * indent.c (compute_motion, vmotion):
24 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start):
25 (get_visually_first_element, move_it_vertically_backward):
26 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
28 2013-02-19 Eli Zaretskii <eliz@gnu.org>
30 * w32proc.c (new_child): Avoid leaking handles if the subprocess
31 resources were not orderly released.
33 2013-02-17 Eli Zaretskii <eliz@gnu.org>
35 * xdisp.c (x_draw_vertical_border): For a window that is neither
36 the leftmost nor the rightmost, redraw both the left and the right
37 vertical borders. (Bug#13723)
39 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
41 * xml.c (init_libxml2_functions):
42 * sound.c (sound_warning):
43 * sheap.c (report_sheap_usage):

52 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
54 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
55 * frame.c (syms_of_frame): ... to here.
57 2013-02-16 Eli Zaretskii <eliz@gnu.org>
59 * w32.c (sys_chown): Remove unused function.
61 * w32term.c <input_signal_count>: Declare 'volatile'
62 unconditionally. (Bug#9066)
64 * w32.c (set_errno): Reset h_errno and don't set it to any other
65 value. Set errno instead.
66 (check_errno): Reset h_errno.
67 (sys_socket, socket_to_fd, sys_bind, sys_connect)
68 (sys_gethostname, sys_getservbyname, sys_getpeername)
69 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
70 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
72 (sys_gethostbyname): Set h_errno only errors detected.
74 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
76 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
78 2013-02-15 Eli Zaretskii <eliz@gnu.org>
80 * keyboard.c (read_char): Fix calculation of auto-save time out
81 when auto-save-timeout is less than 4. (Bug#13720)
83 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
84 time. Improve diagnostics in DebPrint. (Bug#13546)

91 (socket_to_fd): Add assertion against indexing fd_info[] with a
92 value that is out of bounds.
93 (sys_accept): If fd is negative, do not set up the child_process
94 structure for reading.
96 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
98 * composite.c (fill_gstring_header): Remove useless prototype.

110 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
112 Fix AIX port (Bug#13650).
113 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
114 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
115 was #undeffed earlier, so it cannot be used as a macro here.
116 Use the constant and not the macro.
118 2013-02-15 Eli Zaretskii <eliz@gnu.org>
120 * w32proc.c (new_child): If no vacant slots are found in
121 child_procs[], make another pass looking for slots whose process
122 has exited or died. (Bug#13546)
124 * w32.c (sys_pipe): When failing due to file descriptors above
125 MAXDESC, set errno to EMFILE.
126 (_sys_read_ahead): Update cp->status when failing to read serial
127 communications input, so that the status doesn't stay at
128 STATUS_READ_IN_PROGRESS. (Bug#13546)
130 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
132 * gtkutil.c (tb_size_cb): New function.
133 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

137 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
140 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
142 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
144 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
146 * font.c (font_range): Add pos_byte argument. Adjust comment
148 * font.h (font_range): Adjust prototype.
149 * composite.c (autocmp_chars): Pass byte position to font_range.

152 2013-02-13 Glenn Morris <rgm@gnu.org>
154 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
156 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
158 Improve AIX port some more (Bug#13650).
159 With this, it should be as good as it was in 23.3, though it's
160 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
161 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
162 * unexaix.c (start_of_text): Remove.
163 (_data, _text): Declare as char[], not int, as AIX manual suggests.
164 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
165 (orig_load_scnptr, orig_data_scnptr):
166 Now off_t, not long, since they are file offsets.
167 (make_hdr): Use _data, not start_of_data ().
168 This is the key part of the fix.
169 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
170 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
172 * pre-crt0.c (data_start): Initialize to 1.
173 This ports to compilers that optimize the external declaration
174 'int x = 0;' as if it were 'int x;' to shrink the executable.
176 Improve AIX port (Bug#13650).
177 This doesn't fix the bug, but it makes progress: Emacs builds now.
178 * unexaix.c: Include inttypes.h, stdarg.h.
179 (report_error, report_error_1): Mark as _Noreturn.
180 (report_error): Don't report the wrong errno.
181 (report_error_1): Now varargs. All callers changed.
182 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
183 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
184 (write_ptr): Use %p to print address rather than %lx and a cast
185 to unsigned long. Grow buffer a bit, to be safer.
187 2013-02-13 Eli Zaretskii <eliz@gnu.org>
189 * bidi.c (bidi_resolve_neutral): After finding the next
190 non-neutral character, accept NEUTRAL_ON type as well, because
191 directional control characters, such as LRE and RLE, have their
192 type converted to that by bidi_resolve_weak. This avoids aborts
193 when LRE/RLE follows a run of neutrals.
194 (bidi_move_to_visually_next): Assert that return value of
195 bidi_peek_at_next_level is non-negative. Negative values will
198 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
200 Minor getenv-related fixes.
201 * callproc.c (Fcall_process_region) [!DOS_NT]:
202 Avoid unnecessary duplicate call to getenv.
203 * callproc.c (init_callproc):
204 * dispnew.c (init_display):
205 * sysdep.c (sys_subshell):
206 Omit unnecessary cast of getenv or egetenv.
208 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
210 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
213 2013-02-12 Eli Zaretskii <eliz@gnu.org>
215 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
217 (display_line): Set w->region_showing to the value of
218 it->region_beg_charpos, not to -1. This fixes redisplay
219 optimization when cursor is moved up after M->. (Bug#13623)
221 (try_scrolling): Scroll text up more if point is too close to ZV
222 and inside the scroll margin. This makes sure point is moved
223 outside the scroll margin in these cases.
225 * window.h (struct window): region_showing can no longer be
228 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
230 Tune by using memchr and memrchr.
231 * doc.c (Fsnarf_documentation):
232 * fileio.c (Fsubstitute_in_file_name):
233 * search.c (find_newline, scan_newline):
234 * xdisp.c (pos_visible_p, display_count_lines):
235 Use memchr and memrchr rather than scanning byte-by-byte.
236 * search.c (find_newline): Rename from scan_buffer.
237 Omit first arg TARGET, as it's always '\n'. All callers changed.
239 Clean up read_key_sequence a tiny bit more.
240 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
241 (read_key_sequence): Remove unused locals.
243 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
245 Clean up read_key_sequence a bit; reread active keymaps after first event.
246 * keyboard.c (read_char, read_char_x_menu_prompt)
247 (read_char_minibuf_menu_prompt):
248 Replace nmaps+maps with a single `map' arg.
249 (follow_key): Operate on a single map.
250 (active_maps): New function.
251 (test_undefined): Also return true for nil bindings.
252 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
253 a single (composed) keymap. Remember `first_event' to choose the right
254 set of active keymaps. Recompute the set of keymaps after receiving
255 the first event. Remove GOBBLE_FIRST_EVENT.
256 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
257 * keyboard.h (read_char): Update declaration.
258 * lread.c (read_filtered_event): Adjust call to read_char.
260 2013-02-11 Eli Zaretskii <eliz@gnu.org>
262 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
263 Don't use the limitation on backwards movement when lines are truncated
264 in the window. (Bug#13675)
266 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
268 * marker.c (set_marker_internal): If desired position is passed
269 as a marker, avoid call to buf_charpos_to_bytepos.
270 * window.c (Fset_window_point): Omit redundant type checking.
271 (Fset_window_start): Likewise. Format comment.
272 (window_scroll_pixel_based): Use set_marker_restricted_both
273 with character and byte positions obtained from an iterator.
274 (Fset_window_configuration): Use set_marker_restricted_both.
275 * xdisp.c (message_dolog): Likewise.
277 2013-02-10 Eli Zaretskii <eliz@gnu.org>
279 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
280 When text lines are longer than window's screen lines, don't move back
281 too far. This speeds up some redisplay operations. (Bug#13675)
283 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
285 * syntax.c (scan_sexps_forward): Fix byte position calculation
286 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
288 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
290 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
293 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
295 Minor hashing refactoring.
296 * fns.c (SXHASH_REDUCE): Move to lisp.h.
297 (sxhash_float): Return EMACS_UINT, for consistency with the other
299 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
300 non-static inline function and therefore can't use static vars.
301 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
302 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
303 with the other hash functions.
305 2013-02-09 Eli Zaretskii <eliz@gnu.org>
307 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
308 XXXXXX part of the temporary file pattern is not downcased even
309 when w32-downcase-file-names is non-nil. (Bug#13661)
311 * xdisp.c (decode_mode_spec): Remove handling of %t.
313 * msdos.c (careadlinkatcwd): Remove.
315 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
317 * lread.c (skip_dyn_bytes): New function (bug#12598).
318 (read1): Use it. Use getc instead of READCHAR to read bytes.
319 (load_each_byte): Remove. Update users.
321 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
323 * search.c (scan_buffer): Calculate end byte position just once.
324 (scan_newline): Do not recalculate start_byte.
325 (search_command): Use eassert.
326 * syntax.c (struct lisp_parse_state): New member location_byte.
327 (scan_sexps_forward): Record from_byte and avoid redundant
328 character to byte position calculation ...
329 (Fparse_partial_sexp): ... here. Break too long line.
331 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
333 * lisp.h (make_uninit_vector): New function.
334 * alloc.c (Fvector, Fmake_byte_code):
335 * ccl.c (Fregister_ccl_program):
336 * charset.c (Fdefine_charset_internal, define_charset_internal):
337 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
338 * composite.c (syms_of_composite):
339 * font.c (Fquery_font, Ffont_info, syms_of_font):
340 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
341 * ftfont.c (ftfont_shape_by_flt):
342 * indent.c (recompute_width_table):
343 * nsselect.m (clean_local_selection_data):
344 * syntax.c (init_syntax_once):
345 * w32unsubscribe.c (uniscribe_shape):
346 * window.c (Fcurrent_window_configuration):
347 * xfaces.c (Fx_family_fonts):
348 * xselect.c (selection_data_to_lisp_data): Use it.
350 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
352 * coding.c (Fdefine_coding_system_internal): Use AREF where
353 argument is known to be a vector.
354 * fns.c (Flocale_info): Likewise for ASET.
355 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
356 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
358 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
360 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
363 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
364 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
365 updateCollectionBehaviour.
367 * nsterm.m (NEW_STYLE_FS): Remove.
368 (ns_last_use_native_fullscreen): New variable.
369 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
370 (x_set_window_size): Do not take title bar and tool bar into account
371 if isFullscreen returns YES.
372 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
373 (check_native_fs): New function.
374 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
375 (ns_term_init): Remove NEW_STYLE_FS.
376 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
377 and tool bar if isFullscreen returns NO.
378 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
379 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
381 (window:willUseFullScreenPresentationOptions:): New method.
382 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
383 Hide toolbar if not enabled (Bug#13444).
384 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
385 Restore tool bar if enabled, hide it otherwise (Bug#13444).
386 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
387 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
388 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
389 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
390 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
391 (syms_of_nsterm): Add ns-use-native-fullscreen.
393 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
395 * fileio.c (Qchoose_write_coding_system): Now static.
397 2013-02-04 Eli Zaretskii <eliz@gnu.org>
399 * xdisp.c (window_buffer_changed): region_showing can be negative,
400 which still means region is being displayed.
401 (redisplay_internal): Resurrect code that forced redisplay of the
402 whole window when showing region and the mark has changed.
403 Record the new mark position to allow redisplay optimizations.
404 (display_line): If it->region_beg_charpos is non-zero, set the
405 window's region_showing member to -1. (Bug#13623) (Bug#13626)
407 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
408 not bitfield of 1 bit.
410 2013-02-03 Daniel Colascione <dancol@dancol.org>
412 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
413 daemon mode works on cygw32 when Emacs is installed and not just
416 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
418 Avoid file time stamp bug on MS-Windows (Bug#13149).
419 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
420 as FAT32 doesn't update time stamps when truncating them.
421 Also, check that a file time stamp is not a multiple of 100 ns;
422 this should catch all instances of the problem on MS-Windows,
423 as its native file system resolution is 100 ns or worse, and
424 checking for a non-multiple of 100 ns should impose only a small
425 overhead on systems with ns resolution.
427 2013-02-02 Eli Zaretskii <eliz@gnu.org>
429 Avoid encoding file names on MS-Windows when they need to be run
430 through dostounix_filename.
431 * w32.c (normalize_filename): Accept an additional argument
432 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
433 downcase it even if w32-downcase-file-names is non-nil.
434 (dostounix_filename): Accept an additional argument MULTIBYTE and
435 pass it to normalize_filename.
436 (emacs_root_dir): Adjust.
438 * msdos.h (dostounix_filename): Adjust prototype.
440 * w32.h (dostounix_filename): Adjust prototype.
442 * msdos.c (dostounix_filename): Accept an additional argument and
444 (init_environment): Adjust callers of dostounix_filename.
446 * fileio.c (Ffile_name_directory, file_name_as_directory)
447 (directory_file_name, Fexpand_file_name)
448 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
450 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
452 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
453 variables, as egetenv is case-insensitive for DOS_NT.
455 * dired.c (file_name_completion): Don't call Fdirectory_file_name
456 with an encoded file name.
458 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
459 Adjust calls to dostounix_filename.
461 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
463 * unexw32.c (unexec): Adjust call to dostounix_filename.
465 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
467 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
470 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
473 * callproc.c (Fcall_process): Make sure program name in PATH and
474 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
475 is passed to exec/spawnve, which fails unless the file-name
478 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
479 even if w32-quote-process-args is nil.
481 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
483 Fix timestamp bug when write-region appends nothing (Bug#13149).
484 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
485 the file's time stamp doesn't change if Emacs happens to write nothing
486 to the file, and on a buggy file system this could cause Emacs to
487 incorrectly infer that the file system doesn't have the bug.
488 Avoid this problem by inhibiting the inference in this case.
490 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
492 * window.h (struct window): Convert base_line_number, base_line_pos
493 and column_number_displayed members from Lisp_Object to ptrdiff_t.
494 Convert region_showing member from Lisp_Object to bitfield.
495 Remove sequence_number member. Adjust comments.
496 * window.c (sequence_number): Remove.
497 (make_window): Initialize column_number_displayed.
498 * print.c (print_object): Follow the printed representation of
499 frames and print window pointer to distinguish between windows.
500 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
501 * xdisp.c (wset_base_line_number, wset_base_line_pos)
502 (wset_column_number_displayed, wset_region_showing): Remove.
503 (window_buffer_changed, mode_line_update_needed, redisplay_internal)

512 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
513 * dired.c: Include <fcntl.h>.
514 (open_directory): New function, which uses open and fdopendir
515 rather than opendir. DOS_NT platforms still use opendir, though.
516 (directory_files_internal, file_name_completion): Use it.
517 (file_attributes): New function, with most of the old Ffile_attributes.
518 (directory_files_internal, Ffile_attributes): Use it.
519 (file_attributes, file_name_completion_stat): First arg is now fd,
520 not dir name. All uses changed. Use fstatat rather than lstat +
522 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
523 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
524 (emacs_readlinkat): New function, with much of the old
525 Ffile_symlink_p, but with an fd argument for speed.
526 It uses readlinkat rather than careadlinkatcwd, so that it
527 need not assume the working directory.
528 (Ffile_symlink_p): Use it.
529 * filelock.c (current_lock_owner): Use emacs_readlinkat
530 rather than emacs_readlink.
531 * lisp.h (emacs_readlinkat): New decl.
532 (READLINK_BUFSIZE, emacs_readlink): Remove.
533 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.

544 Move the last piece of choose_write_coding_system here. (Bug#13522)
545 (syms_of_fileio): Add choose-write-coding-system.
547 2013-01-30 Eli Zaretskii <eliz@gnu.org>
549 * w32.c (sys_open): Zero out the flags for the new file descriptor.
550 (sys_close): Zero out the flags for the file descriptor before
551 closing it. (Bug#13546)
553 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
554 (logon_network_drive, stat_worker, symlink, chase_symlinks):
555 Use CharNextExA and CharPrevExA to iterate over file names encoded in
558 * w32.c (w32_get_long_filename, init_environment, readlink):
559 Support file names encoded in DBCS codepages.
560 (readlink): Use the current file-name-coding-system, not the ANSI
561 codepage, to decode and handle targets of symlinks.
563 2013-01-28 Eli Zaretskii <eliz@gnu.org>
565 * w32.c (opendir): Now accepts a 'const char *'.
567 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
569 Remove obsolete redisplay code. See the discussion at
570 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
571 * dispnew.c (preemption_period, preemption_next_check): Remove.
572 (Vredisplay_preemption_period): Likewise.
573 (update_frame, update_single_window, update_window, update_frame_1):
574 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
575 used, following the 2012-06-22 change.
577 2013-01-25 Eli Zaretskii <eliz@gnu.org>
579 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
581 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
583 * font.c (num_fonts): Remove the leftover from old
584 debugging code. Adjust comment style here and there.

591 * w32.c (max_filename_mbslen): New function.
592 (normalize_filename, readdir): Use it to detect locales where ANSI
593 encoding of file names uses a double-byte character set (DBCS).
594 If a DBCS encoding is used, advance by characters using
595 CharNextExA, instead of incrementing a 'char *' pointer.
596 Use _mbslwr instead of _strlwr. (Bug#13515)
598 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
599 request of memory reservation to 1.7GB. (Bug#13065)
601 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
603 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
604 at check_extra_latin label. (Bug#13505)
606 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
608 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
609 Avoid redundant calls to strlen.
611 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
613 Drop async_visible and async_iconified fields of struct frame.
614 This is possible because async input is gone; for details, see
615 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
616 * frame.h (struct frame): Remove async_visible and async_iconified
617 members, convert garbaged to unsigned bitfield. Adjust comments.
618 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
619 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
620 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
621 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
622 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
624 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
625 properly. Likewise for obscured.
627 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
630 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
632 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
634 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
635 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
637 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
639 * xdisp.c (message2, message2_nolog): Remove functions.
640 (message3, message3_nolog): Extract nbytes and multibyteness directly
641 from the string. Change all callers.
642 (message3_nolog): Don't set message_enable_multibyte since set_message
643 will reset it anyway.
644 (message1, message1_nolog): Use message3.
645 (vmessage): Use a stack allocated buffer rather than f->message_buf.
646 (with_echo_area_buffer): Remove last two arguments. Update all callers.
647 (set_message): Drop all but the second arg, which has to be a string.
648 (set_message_1): Simplify now that we know that a1 is NULL and the
649 second arg is a string.
650 * frame.h (struct frame): Remove `message_buf' field.
651 Use glyphs_initialized_p instead.
652 (FRAME_MESSAGE_BUF): Remove macro.

656 * keyboard.c (read_char_minibuf_menu_text)
657 (read_char_minibuf_menu_width): Remove vars.
658 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
659 to correctly handle multibyte strings.
660 * frame.c (delete_frame): Don't free message_buf any more.
661 * editfns.c (message_text, message_length): Remove vars.
662 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
663 * fileio.c (auto_save_error): Use message3 instead of message2.
664 * dispnew.c (adjust_frame_message_buffer): Remove function.
666 2013-01-23 Eli Zaretskii <eliz@gnu.org>
668 * w32term.c (w32fullscreen_hook): Account correctly for the screen
669 real estate used for the tool bar and the menu bar.
671 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
673 * insdel.c (prepare_to_modify_buffer): Force redisplay if
674 hidden buffer is prepared to modification (Bug#13164).
676 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
678 * window.h (struct window): Change window_end_valid member from
679 Lisp_Object to a bitfield. Adjust comments.
680 (wset_window_end_valid): Remove.
681 * window.c (adjust_window_count): Clear window_end_valid.
682 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
683 (Fwindow_line_height, set_window_buffer, Frecenter)
684 (Fsplit_window_internal, Fdelete_other_windows_internal)
685 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
686 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
687 * xdisp.c (check_window_end, reconsider_clip_changes)
688 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
689 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
690 (find_first_unchanged_at_end_row, try_window_id): Likewise.
692 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
694 * xdisp.c (mark_window_display_accurate): Simplify the loop
695 assuming that the only one of vchild, hchild or buffer window
696 slots is non-nil. Call mark_window_display_accurate_1 for
697 the leaf windows only.
698 (mark_window_display_accurate_1): Always assume leaf window.
701 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
703 * emacs.c (Qkill_emacs_hook): Now static.
705 * fileio.c (Finsert_file_contents): Simplify.
706 Remove unnecessary assignments and tests.
708 2013-01-21 Eli Zaretskii <eliz@gnu.org>
710 * w32.c (acl_set_file): Don't test for errors unless
711 set_file_security returns FALSE. Avoids spurious errors when
714 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
716 * fileio.c (Finsert_file_contents): Revert code introduced at
717 2013-01-18 in favor of the simpler and generally better fix.
718 Save stack space by removing 'buffer' and reusing 'read_buf'
721 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
723 * lisp.h (eabs): Define unconditionally (Bug#13419).
724 The old "#if !defined (eabs)" was an unnecessary revenant of back
725 when this macro was called "abs". Document 'eabs' better.
727 2013-01-19 Glenn Morris <rgm@gnu.org>
729 * fns.c (Frandom): Doc fix.
731 2013-01-19 Eli Zaretskii <eliz@gnu.org>
733 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
734 segfault when there are lots of overlays.
736 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
737 when there are lots of overlays.
738 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
739 for the details and a way to reproduce.
741 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
743 * fileio.c: Use O_APPEND to append.
744 This corresponds better to the natural interpretation of "append",
745 and avoids the need to open the output file twice, or to invoke
746 lseek when APPEND is neither nil nor a number.
747 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
748 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
749 file possibly twice, and lseeking to its end; this avoids the
750 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
751 at the same time: the combination is never needed and apparently
752 it doesn't work with DOS_NT.
754 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
755 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
757 Allow floating-point file offsets.
758 Problem reported by Vitalie Spinu in
759 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
760 * fileio.c (emacs_lseek): Remove.
761 (file_offset): New function.
762 (Finsert_file_contents, Fwrite_region): Use it.
764 2013-01-19 Chong Yidong <cyd@gnu.org>
766 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
767 aborting on Fsignal (Bug#13289).
769 2013-01-19 Eli Zaretskii <eliz@gnu.org>
771 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
772 set_file_security as failure due to insufficient privileges.
773 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
774 (fstat): Return owner and group like 'stat' and 'lstat' do.
776 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
778 Work around bug in CIFS and vboxsf file systems (Bug#13149).
779 The bug was observed on Ubuntu operating inside a virtual machine,
780 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
781 The workaround introduces a race condition on non-buggy hosts,
782 but it's an unlikely race and anyway there's a nearly identical
783 nearby race that can't be fixed.
784 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
786 (Fwrite_region): Test for file system time stamp bug.
787 (init_fileio): New function.
788 * lisp.h (init_fileio): Declare it.
789 * emacs.c (main): Call it.
791 * fileio.c (Finsert_file_contents): Simplify new diagnostic
792 and make it more consistent with other stat-failure diagnostics.
794 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
796 Fix crash when inserting data from non-regular files.
797 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
798 for the error description produced by valgrind.
799 * fileio.c (read_non_regular): Rename to read_contents.
800 Free Lisp_Save_Value object used to pass parameters.
801 (read_non_regular_quit): Rename to read_contents_quit.
802 (Finsert_file_contents): Redesign internal file reading loop to adjust
803 gap and end positions after each read and so help make_gap to work
804 properly. Do not signal an I/O error too early and so do not leave
805 not yet decoded characters in a buffer, which was the reason of
806 redisplay crash. Use list2 to build return value. Adjust comments.
808 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
810 Close a race when statting and reading files (Bug#13149).
811 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
812 This avoids a race if the file is renamed between stat and open.
813 This race is not the problem originally noted in Bug#13149;
814 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
816 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

824 * alloc.c (format_save_value): Rename to make_save_value.
825 (make_save_pointer): New function.
826 (record_xmalloc): Use make_save_pointer.
827 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
828 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
829 Change users of make_save_value to make_save_pointer.
830 Likewise for format_save_value and make_save_value.

848 (non_regular_nbytes): Remove.
849 (Finsert_file_contents): Convert trytry to ptrdiff_t.
850 Use format_save_value to pass parameters to read_non_regular.
851 (read_non_regular): Use XSAVE_ macros to extract parameters.
853 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
855 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
857 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
859 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
860 extraction from any Lisp_Save_Value slot. Add type checking.
861 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
862 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
863 * xselect.c: All users changed.
865 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
867 Some convenient bits to deal with Lisp_Save_Values.

880 Avoid needless casts with XSAVE_POINTER.
881 * alloc.c (mark_object) [GC_MARK_STACK]:
882 * dired.c (directory_files_internal_unwind):
883 * fileio.c (do_auto_save_unwind):
884 * gtkutil.c (pop_down_dialog):
885 * keymap.c (map_keymap_char_table_item):
886 * lread.c (load_unwind):
887 * nsmenu.m (pop_down_menu):
888 * print.c (print_object) [GC_MARK_STACK]:
889 * xfns.c (clean_up_file_dialog):
890 * xmenu.c (cleanup_widget_value_tree):
891 Omit casts between XSAVE_POINTER and a pointer type.
893 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
895 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
896 * eval.c (eval_sub): Protect `form' from being GCed before its
897 car and cdr becomes protected with the backtrace entry.

908 * alloc.c (allocate_misc): Now global.
909 (free_misc): Likewise. Adjust comment.
910 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
911 (free_save_value): Likewise.
912 (mark_object): Likewise.
913 * editfns.c (save_excursion_save): Pack everything within
914 Lisp_Save_Value and so avoid xmalloc.
915 (save_excursion_restore): Adjust to match new layout. Use free_misc
916 because we do not allocate extra memory any more. Add eassert.
917 * print.c (print_object): New code to print Lisp_Save_Value. Do not
918 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
919 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
920 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
921 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.

957 Remove check for fkeys count > zero, block/unblock fixes the real bug.
958 (nsfont_list_family): Add block/unblock_input calls.
959 (nsfont_open): Move block_input earlier. Add unblock_input before early
961 (nsfont_draw): Add block/unblock_input calls.

984 string cross-reference(s).
986 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
988 Avoid unnecessary byte position calculation for the gap movement.
989 Since all users of move_gap do CHAR_TO_BYTE for other purposes
990 anyway, all of them should use move_gap_both instead.

1000 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1002 * term.c (init_tty): Use them instead of rolling our own code.
1003 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1004 switches from 'signal' to 'pthread_sigmask', which is safer in
1005 multithreaded applications.
1006 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1007 which has already arranged for that.
1008 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1009 This is the main part of the bug fix.

1029 right-fringe-width, scroll-bar-width and buffer-display-count.
1030 Use Qstringp for default-directory, buffer-file-name,
1031 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1032 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1034 * data.c (store_symval_forwarding): Adjust to call the predicate.

1050 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1051 (make_gap_1): New function to adjust the gap of any buffer.
1052 * coding.c (coding_alloc_by_making_gap): Use it.
1053 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1054 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

1077 trailing dash is properly added.
1079 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1081 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1082 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1083 digits for buffer positions, before misalignment starts.
1084 Display "0" for integer "object" field.
1085 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1086 Display the newline glyph more unambiguously.
1088 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1090 * nsterm.m (ns_draw_underwave):
1091 * w32term.c (w32_draw_underwave):
1092 * xterm.c (x_draw_underwave): Make underwave look more triangular
1093 and also degrade gracefully for small fonts. (Bug#13000)
1095 * nsterm.m (ns_draw_text_decoration):
1096 * w32term.c (x_draw_glyph_string):
1097 * xterm.c (x_draw_glyph_string): Don't use previous underline
1098 thickness and position if previous underline type is underwave.
1100 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1102 * fileio.c (Ffile_acl): Undocument return format.
1104 2013-01-02 Glenn Morris <rgm@gnu.org>
1106 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

1118 * term.c (tty_ins_del_lines):
1119 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1120 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1122 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1124 * w32.c (unsetenv): Set up the string passed to _putenv
1126 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1127 for the bug this caused.
1129 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1131 * coding.c (Qmac): Now static.
1133 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1135 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1136 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1143 by TOOLBAR_TOP_WIDGET.
1144 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1145 Check toolbar_is_packed.
1146 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1148 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1150 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1151 (xg_update_menubar): Update title only if
1152 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1153 (xg_update_submenu): Skip tearoff only if
1154 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1155 (xg_initialize): Initialize xg_detached_menus only if
1156 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1158 * xterm.h (struct x_output): Surround handlebox_widget with
1159 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1160 toolbar_in_hbox is bool.
1162 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1164 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1165 (LIBS_GNUSTEP): Define.
1166 (LIBES): Add $(LIBS_GNUSTEP).

1169 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1171 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1172 continuation glyph on a TTY with an indication of an empty line.
1175 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1177 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1178 file's SELinux context or ACLs successfully set, nil otherwise.
1180 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

1183 SetEvent and WaitForSingleObject.
1185 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1187 Port EXTERNALLY_VISIBLE to Clang 3.2.
1188 * conf_post.h (__has_attribute): New macro.
1189 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1191 2012-12-27 Glenn Morris <rgm@gnu.org>
1193 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1194 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1196 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1198 * fileio.c (file_name_as_directory, directory_file_name):
1199 Accept an additional argument MULTIBYTE to indicate whether the input C
1200 came from a multibyte or a unibyte Lisp string; all callers
1201 adjusted. Don't assume the input string is always multibyte.
1203 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1204 don't ENCODE_FILE them, and return a unibyte string if the input
1206 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1207 don't assume the input strings will always be multibyte. If the
1208 input strings are multibyte, decode strings obtained from C
1211 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1213 * lisp.h (toplevel): Add two notices to the comment about
1214 defining a new Lisp data type.

1218 * alloc.c (valid_lisp_object_p): Adjust comment.
1220 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1222 * keyboard.c (record_asynch_buffer_change): Initialize an event
1223 only if it's really needed.
1224 * frame.h (enum output_method): Remove output_mac member since
1225 it's a leftover from the deleted code.
1226 * frame.c (Fframep): Adjust user here ...
1227 * terminal.c (Fterminal_live_p): ... and here.
1228 * coding.c (Qmac): Now here because it's only used to denote
1229 end-of-line encoding type.
1230 (syms_of_coding): DEFSYM it.
1231 * frame.h (Qmac): Remove duplicated declaration.
1233 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1235 * window.c (select_window_1): Now static, since it's used only here.
1237 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1239 * window.c (window_body_cols): Subtract display margins from the
1240 window body width on TTYs as well. See
1241 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1242 for the original report.
1244 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1246 * xdisp.c (redisplay_window): Remove inner local variable
1247 because the outer shadowed one has the same meaning.
1248 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1250 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1251 (xg_create_tool_bar): Adjust users.
1253 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1255 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1256 * buffer.c (Fget_buffer_create): Use it to set compact field of
1257 struct buffer_text to avoid accessing an uninitialized value
1258 when compact_buffer is called for the first time.
1259 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1260 (Fset_buffer_modified_p): Use buffer_window_count to check
1261 whether the buffer is displayed in some window.
1262 * xdisp.c (message_dolog): Likewise.
1264 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1266 * w32.c (acl_set_file): If setting the file security descriptor
1267 fails, and the new DACL is identical to the existing one, silently
1268 return success. This fixes problems for users backing up their
1269 own files without having the necessary privileges for setting
1270 security descriptors.
1272 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1274 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1275 after WaitForSingleObject returns normally. This expedites reader
1276 thread shutdown when delete_child triggers it.
1277 (reap_subprocess): More accurate commentary for why we call
1278 delete_child only when cp->fd is negative.
1280 * w32.c (sys_close): Do not call delete_child on a subprocess
1281 whose handle is not yet closed. Instead, set its file descriptor
1282 to a negative value, so that reap_subprocess will call
1283 delete_child on that subprocess when its SIGCHLD arrives.
1284 This avoids closing handles used for communications between sys_select
1285 and reader_thread, which doesn't give sys_select a chance to
1286 notice that the process exited and invoke the SIGCHLD handler for
1289 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1291 * nsfns.m (Fns_do_applescript): Run event loop until script has

1300 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1302 * w32term.c (w32fullscreen_hook): New function.
1303 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1305 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1307 * fileio.c (Finsert_file_contents): Doc fix.
1309 * w32proc.c (new_child, delete_child, find_child_pid): For a
1310 subprocess, consider its slot being in use as long as its process
1311 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1312 slot when a new process is started immediately after killing
1313 another one, without waiting enough time for the first process to
1314 be reaped and resources allocated for it be orderly freed.
1316 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1318 2012-12-21 Chong Yidong <cyd@gnu.org>
1320 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1322 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1324 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1326 * w32.c (get_name_and_id): Always pass NULL as the first argument
1327 of lookup_account_sid. Avoids crashes with UNC file names that
1328 refer to DFS domains, not to specific machine names. (Bug#12621)
1329 Remove now unused argument FNAME; all callers changed.
1330 (get_file_owner_and_group): Remove now unused argument FNAME; all
1333 2012-12-21 Chong Yidong <cyd@gnu.org>
1335 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1336 error for invalid chars, don't check for a nil return value.
1338 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1340 Avoid calls to CHAR_TO_BYTE if byte position is known.
1341 * editfns.c (make_buffer_string_both): Use move_gap_both.

1345 (buf_bytepos_to_charpos): Likewise.
1346 (charpos_to_bytepos): Remove.
1347 * fileio.c (Finsert_file_contents): Use move_gap_both.
1348 * search.c (Freplace_match): Likewise.
1349 * process.c (process_send_region): Likewise. Use convenient
1350 names for byte positions.
1351 * lisp.h (charpos_to_bytepos): Remove prototype.
1352 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1353 * insdel.c (move_gap): Likewise.

1361 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1362 (redisplay_internal): Don't bother selecting the frame to get the
1363 proper value of frame-local variables (bug#13225).
1365 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1367 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1368 Rename 4th argument since it may be buffer or string. Adjust comment.
1369 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1371 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1373 * coding.c (Fdetect_coding_region): Do not check start and end with
1374 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1375 (code_convert_region): Likewise.
1377 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1379 * w32.c (acl_get_file, acl_set_file): Run the file name through
1380 map_w32_filename, and resolve any symlinks in the file name, like
1382 (acl_set_file): Call revert_to_self, if any privileges were
1385 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1387 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1388 ($(BLD)/w32.$(O)): Update dependencies.
1390 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1392 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1393 propagate redisplay's scrolling (if any) to the right window.
1394 (redisplay_internal): Use ensure_selected_frame.
1395 (display_mode_lines): Complete last fix.
1396 * window.c (select_window_1): New func, extracted from select_window.
1397 (select_window): Use it.

1424 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1426 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1427 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1428 for some of that bug's symptoms can now cause Emacs to abort.
1429 Remove the workaround.
1430 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1431 The bug that caused SIGCHLD to get lost has been fixed, and the
1432 workaround for it can now cause Emacs to abort.
1434 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1436 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1442 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1443 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1444 and copy ACL entries of file in addition to SELinux context if set.
1445 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1447 * Makefile.in (LIBACL_LIBS): New macro.

1462 * w32proc.c (new_child): Initialize input_file and
1463 pending_deletion members of the child.
1464 (delete_child): Delete the child's temporary input file, if any,
1465 that is pending deletion.
1466 (register_child): First argument is now pid_t.
1467 (record_infile, record_pending_deletion): New functions.
1468 (reap_subprocess): Fix a typo in DebPrint string.
1469 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1471 * fileio.c (internal_delete_file): Return an int again: non-zero

1476 * callproc.c (Fcall_process): Don't overwrite infile with result
1478 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1479 asynchronous subprocess, record the name of the input file name,
1481 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1482 delete the file, record it as pending deletion when the subprocess
1485 2012-12-14 Eli Zaretskii <eliz@gnu.org>

1505 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1507 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1508 try to get accurate owner and group information from NT file
1509 security APIs. This is to make most callers of 'stat' and
1510 'lstat', which don't need that information, much faster.
1512 * dired.c (Ffile_attributes) [WINDOWSNT]:
1513 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1514 owner and group information from 'lstat'.
1516 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1518 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1519 as that confuses set-auto-coding, so insist on the head-read
1520 returning the full 1024 bytes. Let lseek compute the tail offset;
1521 less work for us. Do not ignore I/O errors when reading the tail.

1545 files, fixing a regression from 24.2.
1546 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1548 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1550 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1551 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1552 Remove unnecessary S_ISLNK test, as (contra the comments) this
1553 function can't copy symlinks. Improve quality of error message
1554 when attempting to copy files that are neither regular files nor

1573 * inotify.c (inotify_callback): Generate an Emacs event for every
1574 incoming inotify event.
1576 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1578 * xdisp.c (handle_face_prop): Fix logic of computing
1579 it->start_of_box_run_p.
1580 (append_space_for_newline): If the glyph row is R2L, reset the
1581 iterator's end_of_box_run_p flag before prepending the space glyph.
1582 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1583 iterator's start_of_box_run_p flag before prepending the stretch.

1586 left_box_line_p and right_box_line_p flags of the glyph for R2L
1587 glyph rows. (Bug#13011)

1637 (hinst): Remove unneeded extern declaration.
1638 (_start): Remove initialization of above variables; remove

1897 This does not change call_process_kill's behavior.
1898 * process.c (Fdelete_process): Use record_kill_process to fix a
1899 race condition that could cause Emacs to lose track of a child.
1901 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1903 Avoid code duplication between prev_frame and next_frame.
1904 * frame.c (candidate_frame): New function. Add comment.
1905 (prev_frame, next_frame): Use it. Adjust comment.
1907 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1909 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1910 fails, signal an error instead of continuing with an empty
1912 Encode expanded temp file pattern before passing it to mkstemp or
1915 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1916 Encode the file name before passing it to dostounix_filename, in
1917 case it will downcase it (under w32-downcase-file-names).
1920 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1922 Minor call-process cleanups.
1923 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1924 at the same time as other platforms, to simplify analysis.
1925 No need for fd0_volatile since we have synch_process_fd.
1926 Avoid needless emacs_close; arg is always negative.
1928 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1930 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1933 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1935 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1936 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1937 and mouse_face_hidden members to a bitfields.
1938 * frame.h (struct frame): Remove set-but-not-used space_width member.
1939 (FRAME_SPACE_WIDTH): Remove.
1940 * nsterm.m, w32term.c, xterm.c: Adjust users.
1941 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1942 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1943 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1944 members to a bitfields.
1946 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1948 Don't let call-process be a zombie factory (Bug#12980).
1949 Fixing this bug required some cleanup of the signal-handling code.
1950 As a side effect, this change also fixes a longstanding rare race
1951 condition whereby Emacs could mistakenly kill unrelated processes,
1952 and it fixes a bug where a second C-g does not kill a recalcitrant
1953 synchronous process in GNU/Linux and similar platforms.
1954 The patch should also fix the last vestiges of Bug#9488,
1955 a bug which has mostly been fixed on the trunk by other changes.
1956 * callproc.c, process.h (synch_process_alive, synch_process_death)
1957 (synch_process_termsig, sync_process_retcode):
1958 Remove. All uses removed, to simplify analysis and so that
1959 less consing is done inside critical sections.
1960 * callproc.c (call_process_exited): Remove. All uses replaced
1961 with !synch_process_pid.
1962 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1963 These take the role of what used to be in unwind-protect arg.
1965 (block_child_signal, unblock_child_signal):
1966 New functions, to avoid races that could kill innocent-victim processes.
1967 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1968 (call_process_kill): Record killed processes as deleted, so that
1969 zombies do not clutter up the system. Do this inside a critical
1970 section, to avoid a race that would allow the clutter.
1971 (call_process_cleanup): Fix code so that the second C-g works again
1972 on common platforms such as GNU/Linux.
1973 (Fcall_process): Create the child process in a critical section,
1974 to fix a race condition. If creating an asynchronous process,
1975 record it as deleted so that zombies do not clutter up the system.
1976 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1977 light of these changes. Omit unnecessary call to emacs_close
1978 before failure, as the unwind-protect code does that.
1979 * callproc.c (call_process_cleanup):
1980 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1981 * process.c (record_deleted_pid): New function, containing
1982 code refactored out of Fdelete_process.
1983 (Fdelete_process): Use it.
1984 (process_status_retrieved): Remove. All callers changed to use
1985 child_status_change.
1986 (record_child_status_change): Remove, folding its contents into ...
1987 (handle_child_signal): ... this signal handler. Now, this
1988 function is purely a handler for SIGCHLD, and is not called after
1989 a synchronous waitpid returns; the synchronous code is moved to
1990 wait_for_termination. There is no need to worry about reaping
1991 more than one child now.
1992 * sysdep.c (get_child_status, child_status_changed): New functions.
1993 (wait_for_termination): Now takes int * status and bool
1994 interruptible arguments, too. Do not record child status change;
1995 that's now the caller's responsibility. All callers changed.
1996 Reimplement in terms of get_child_status.
1997 (wait_for_termination_1, interruptible_wait_for_termination):
1998 Remove. All callers changed to use wait_for_termination.
1999 * syswait.h: Include <stdbool.h>, for bool.
2000 (record_child_status_change, interruptible_wait_for_termination):
2002 (record_deleted_pid, child_status_changed): New decls.
2003 (wait_for_termination): Adjust to API changes noted above.
2005 * bytecode.c, lisp.h (Qbytecode): Remove.
2006 No longer needed after 2012-11-20 interactive-p changes.
2008 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2010 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2011 the scroll margin, move point outside the margin. (Bug#13055)
2013 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2015 * gtkutil.c (my_log_handler): New function.
2016 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2018 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2020 * lisp.h (modify_region): Rename to...
2021 (modify_region_1): ...new prototype.
2022 * textprop.c (modify_region): Now static. Adjust users.
2023 * insdel.c (modify_region): Rename to...
2024 (modify_region_1): ...new function to work with current buffer.
2025 Adjust comment and users. Use true and false for booleans.
2027 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2029 * alloc.c (free_save_value): New function.
2030 (safe_alloca_unwind): Use it.
2031 * lisp.h (free_save_value): New prototype.
2032 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2034 (save_excursion_restore): Adjust to match saved data structure.
2035 Use free_save_value to offload some work from GC. Drop obsolete
2038 2012-12-03 Chong Yidong <cyd@gnu.org>
2040 * fileio.c (Vauto_save_list_file_name): Doc fix.
2042 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2044 * w32fns.c: Remove prototype of atof.
2045 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2047 (file_dialog_callback): Make it UINT_PTR.
2049 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2052 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2053 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2056 2012-12-03 Glenn Morris <rgm@gnu.org>
2058 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2060 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2062 Fix xpalloc confusion after memory is exhausted.
2063 * alloc.c (xpalloc): Comment fix.
2064 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2065 and signals an error, do not clear charset_table_size, as
2066 charset_table is still valid.
2067 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2069 Use execve to avoid need to munge environ (Bug#13054).
2070 * callproc.c (Fcall_process):
2071 * process.c (create_process):
2072 Don't save and restore environ; no longer needed.
2073 * callproc.c (child_setup):
2074 Use execve, not execvp, to preserve environ.
2076 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2078 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2080 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2082 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2083 display for sliced images (Bug#10500).
2085 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2087 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2089 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2090 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2092 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2094 * xdisp.c (window_outdated): Remove eassert since it hits
2095 some suspicious corner cases (see Bug#13007 and Bug#13012).
2096 (mode_line_update_needed): New function.
2097 (redisplay_internal, redisplay_window): Use it.
2098 (ensure_selected_frame): New function.
2099 (redisplay_internal, unwind_redisplay): Use it.
2100 (redisplay_internal): Move comment about buffer_shared...
2101 (buffer_shared_and_changed): ...near to its real use.
2103 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2105 * callproc.c (Fcall_process): Don't misreport vfork failure.
2107 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2109 * callproc.c (Fcall_process): Fix vfork portability problems.
2110 Do not assume that fd[0], count, filefd, and save_environ survive
2111 vfork. Fix bug whereby wrong errno value could be reported for
2112 pipe failure. Some minor cleanups, too, as follows. Move buf and
2113 bufsize to the context where they're needed. Change new_argv to
2114 be of type char **, as this is more convenient and avoids casts.
2115 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2116 Now local constants, not macros.
2118 2012-11-18 Kenichi Handa <handa@gnu.org>
2120 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2121 for the variable "f".
2123 2012-11-13 Kenichi Handa <handa@gnu.org>
2125 * font.c (font_unparse_xlfd): Exclude special characters from the
2126 generating XLFD name.
2128 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2144 * unexcoff.c (write_segment): Assume EFAULT is defined.
2146 2012-11-27 Eli Zaretskii <eliz@gnu.org>

2168 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2169 between bpos_covered and bpos_max. This fixes cursor display when
2170 several display strings follow each other.
2172 * .gdbinit (pgx): If the glyph's object is a string, display the
2173 pointer to string data, rather than the value of the string object
2174 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2176 * indent.c (Fvertical_motion): If the starting position is covered
2177 by a display string, return to one position before that, to avoid
2178 overshooting it inside move_it_to. (Bug#12930)
2180 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2191 Drop unused pending_menu_activation member.
2192 * xterm.h (struct x_output): Drop outdated #if 0 code.
2193 Use bitfields for explicit_parent, asked_for_visible,
2194 has_been_visible and net_wm_state_hidden_seen members.

2199 of a literal "/". (Bug#12955)
2200 (gl-stamp): Invoke fc.exe directly, not through cmd.
2202 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

2205 * dired.c: Assume HAVE_DIRENT_H.
2206 (NAMLEN): Remove, replacing with ...
2207 (dirent_namelen): New function. All uses changed. Use the GNU macro
2208 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2209 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2210 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2211 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2213 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2214 * ndir.h: Rename to ../nt/inc/dirent.h.
2215 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2216 Do not include <dirent.h>; no longer needed.
2217 * w32.c: Include <dirent.h> rather than "ndir.h".
2219 2012-11-23 Chong Yidong <cyd@gnu.org>
2221 * xftfont.c (xftfont_open): Remove duplicate assignment.
2223 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2225 * alloc.c (Fgarbage_collect): Unblock input after clearing
2226 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2227 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2228 * msdos.c (IT_frame_up_to_date): Use it here...
2229 * w32term.c (w32_frame_up_to_date): ...here...
2230 * xterm.c (XTframe_up_to_date): ...and here...
2231 * nsterm.m (ns_frame_up_to_date): ...but not here.

2239 * xdisp.c (window_buffer_changed): New function.
2240 (update_menu_bar, update_tool_bar): Use it to
2241 simplify large 'if' statements.

2243 'tail' and 'frame' local variables.
2245 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2247 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2248 with Windows system header.

2270 Cygwin builds, not just GTK builds. See
2271 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2273 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2275 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2276 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2277 Define for the MSVC compiler.
2279 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2281 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2282 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2283 dostounix_filename. Prevents crashes down the road, because
2284 dostounix_filename assumes it gets a unibyte string.
2285 Reported by Michel de Ruiter <michel@sentient.nl>, see

2324 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2325 cygwin_convert_file_name*.

2334 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2336 * w32select.c: Include w32common.h before w32term.h, so that
2337 windows.h gets included before w32term.h uses some of its
2338 features, see below.
2340 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2342 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2351 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2353 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2354 Needed following 2012-10-20 change. (Bug#12902)
2356 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2358 * w32proc.c (waitpid): Remove unused label get_result.
2360 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2362 * makefile.w32-in (SYSWAIT_H): New macro.
2363 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2364 ($(BLD)/sysdep.$(O)): Update dependencies.
2366 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2368 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2369 * callproc.c (relocate_fd): Assume F_DUPFD.
2370 * emacs.c, term.c (O_RDWR): Remove.
2371 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2372 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2373 * nsterm.m: Assume <fcntl.h> exists.
2374 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2375 (create_pty, Fmake_network_process, server_accept_connection)
2376 (wait_reading_process_output, init_process_emacs):
2378 (wait_reading_process_output): Put in a special case for WINDOWSNT
2379 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2380 It's not clear this is needed, but it's a more-conservative change.
2381 (create_process): Assume FD_CLOEXEC.
2382 (create_process, create_pty): Assume O_NOCTTY.
2383 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2384 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2385 Omit if not DOS_NT, since F_GETFL is not defined there.
2386 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2387 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2389 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2390 lack it, since gnulib guarantees this.
2391 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2393 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2395 * w32.c (faccessat): Pretend that directories have the execute bit
2396 set. Emacs expects that, e.g., in files.el:cd-absolute.
2398 * w32proc.c (create_child): Don't clip the PID of the child
2399 process to fit into an Emacs integer, as this is no longer a
2401 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2402 reaping only the process specified by PID argument, if that is
2403 positive. Use PID instead of dead_child to know which process to
2404 reap. Wait for the child to die only if WNOHANG is not in
2406 (sys_select): Don't set dead_child.
2408 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2409 as it is no longer needed.
2411 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2413 (record_child_status_change): Remove the setting of
2414 record_at_most_one_child for the !WNOHANG case.
2416 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2418 Fix problems in ns port found by static checking.
2419 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2420 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2421 not to process group.
2422 (ns_select): Use emacs_write, not write, as that's more robust
2423 in the presence of signals.
2424 (fd_handler:): Check for read errors.
2426 2012-11-16 Glenn Morris <rgm@gnu.org>
2428 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2430 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2432 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2434 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2436 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2437 use the same value of thread handle.
2438 (start_timer_thread): If the timer thread exited (due to error),
2439 clean up by closing the two handles it used. Duplicate the caller
2440 thread's handle here, so it gets duplicated only once, when
2441 launching the timer thread. Set priority of the timer thread, not
2443 (getitimer): Don't duplicate the caller thread's handle here.
2446 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2448 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2451 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2453 Remove no-longer-used pty_max_bytes variable.
2454 * process.c (pty_max_bytes): Remove; unused.
2455 (send_process): Do not set it.
2457 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2459 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2460 Update dependencies.
2462 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2464 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2465 This follows up on the 2012-09-29 patch that removed indirection
2466 for the 'function' field. Reported by Sergey Vinokurov in
2467 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2469 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2471 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2472 different name, as the MS runtime does not have such a function,
2473 and probably never will.) All callers changed. Ignore DIRFD
2474 value if PATH is an absolute file name, to match Posix spec
2475 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2478 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2480 * xdisp.c (echo_area_display, redisplay_internal):
2481 Omit redundant check whether frame_garbaged is set.
2483 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2485 Use faccessat, not access, when checking file permissions (Bug#12632).
2486 This fixes a bug that has been present in Emacs since its creation.
2487 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2488 which must set some sort of record. (Torek's bug report was against
2489 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2490 same common flaw.) See Torek's Usenet posting
2491 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2492 Posted: Fri Apr 8 14:18:56 1983.
2493 * Makefile.in (LIB_EACCESS): New macro.
2495 * callproc.c (init_callproc):
2496 * charset.c (init_charset):
2497 * fileio.c (check_existing, check_executable, check_writable)
2499 * lread.c (openp, load_path_check):
2500 * process.c (allocate_pty):
2502 Use effective UID when checking permissions, not real UID.
2503 * callproc.c (init_callproc):
2504 * charset.c (init_charset):
2505 * lread.c (load_path_check, init_lread):
2506 Test whether directories are accessible, not merely whether they exist.
2507 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2508 * fileio.c (check_existing, check_executable, check_writable)
2510 Use symbolic names instead of integers for the flags, as they're
2512 (check_writable): New arg AMODE. All uses changed.
2513 Set errno on failure.
2514 (Ffile_readable_p): Use faccessat, not stat + open + close.
2515 (Ffile_writable_p): No need to call check_existing + check_writable.
2516 Just call check_writable and then look at errno. This saves a syscall.
2517 dir should never be nil; replace an unnecessary runtime check
2518 with an eassert. When checking the parent directory of a nonexistent
2519 file, check that the directory is searchable as well as writable, as
2520 we can't create files in unsearchable directories.
2521 (file_directory_p): New function, which uses 'stat' on most platforms
2522 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2523 (Ffile_directory_p, Fset_file_times): Use it.
2524 (file_accessible_directory_p): New function, which uses a single
2525 syscall for efficiency.
2526 (Ffile_accessible_directory_p): Use it.
2527 * xrdb.c (file_p): Use file_directory_p.
2528 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2529 * lread.c (openp): When opening a file, use fstat rather than
2530 stat, as that avoids a permissions race. When not opening a file,
2531 use file_directory_p rather than stat.
2532 (dir_warning): First arg is now a usage string, not a format.
2533 Use errno. All uses changed.
2534 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2535 that merely introduced a race.
2536 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2537 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2538 and similarly for the other O_* flags.
2539 * w32.c (sys_faccessat): Rename from sys_access and switch to
2540 faccessat's API. All uses changed.
2541 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2542 (magic_db): Rename from magic_file_p.
2543 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2544 char *, so that we don't have to test for file existence
2545 separately from opening the file for reading. This removes a race
2546 fixes a permission-checking problem, and simplifies the code.
2548 (file_p): Remove; no longer needed.
2550 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2552 Omit glyphs initialization at startup.
2553 * dispnew.c (glyphs_initialized_initially_p): Remove.
2554 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2555 (Fredraw_frame): Move actual code from here...
2556 (redraw_frame): ...to here. Add eassert. Adjust comment.
2557 (Fredraw_display): Use redraw_frame.
2558 * xdisp.c (clear_garbaged_frames): Likewise.
2560 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2562 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2563 passed to pint2str and pint2hrstr to be at most the size of the
2564 frame's decode_mode_spec_buffer. This avoids crashes with very
2565 large values of FIELD_WIDTH argument to decode_mode_spec.
2568 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2570 Fix a race with verify-visited-file-modtime (Bug#12863).
2571 Since at least 1991 Emacs has ignored an mtime difference of no
2572 more than one second, but my guess is that this was to work around
2573 file system bugs that were fixed long ago. Since the race is
2574 causing problems now, let's remove that code.
2575 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2576 whose time stamp is off by no more than a second. Insist that the
2577 file time stamps match exactly.
2579 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2581 * frame.h (struct frame): Convert external_tool_bar member to
2582 1-bit unsigned bitfield.
2583 * termhooks.h (struct terminal): Remove mouse_moved member since
2584 all users are long dead. Adjust comment on mouse_position_hook.
2586 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2588 Simplify by using FOR_EACH_FRAME here and there.
2589 * frame.c (next_frame, prev_frame, other_visible_frames)
2590 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2591 * w32term.c (x_window_to_scroll_bar): Likewise.
2592 * window.c (window_list): Likewise.
2593 * xdisp.c (x_consider_frame_title): Likewise.
2594 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2595 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2596 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2597 * xmenu.c (menubar_id_to_frame): Likewise.
2598 * xselect.c (frame_for_x_selection): Likewise.
2599 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2600 (x_window_to_menu_bar): Likewise.
2601 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2603 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2605 * data.c (Qdefalias_fset_function): Now static.
2607 Another tweak to vectorlike_header change.
2608 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2609 Remove, and replace all uses with ...
2610 (next_in_free_list, set_next_in_free_list):
2611 New functions, which respect C's aliasing rules better.
2613 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2615 * window.c (list4i): Rename from 'quad'. All uses changed.
2616 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2618 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2620 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2621 warning about mixing declarations and code in ISO C90.
2623 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2625 * window.c (Fsplit_window_internal): Set combination limit of
2626 new parent window to t iff Vwindow_combination_limit is t;
2627 fixing a regression introduced with the change from 2012-09-22.
2628 (Fset_window_combination_limit): Fix doc-string.
2630 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2632 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2633 amount when the scroll margins are too large. When scrolling
2634 backwards in the buffer, give up if cannot reach point or the
2635 scroll margin within a reasonable number of screen lines.
2636 Fixes point position in window under scroll-up/down-aggressively when
2637 point is positioned many lines beyond the window top/bottom.
2640 * ralloc.c (relinquish): If real_morecore fails to return memory
2641 to the system, don't crash; instead, leave the last heap
2642 unchanged and return. (Bug#12774)
2644 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2646 * lisp.h (AUTOLOADP): New macro.
2647 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2648 * data.c (Ffset): Remove special ad-advice-info handling.
2649 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2651 (Finteractive_form): Simplify.
2652 (Fquo): Don't insist on having at least 2 arguments.
2653 (Qdefalias_fset_function): New var.
2655 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2657 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2663 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2665 Fix recently introduced crash on MS-Windows (Bug#12839).
2666 * w32term.h (struct scroll_bar): Use convenient header.
2667 (SCROLL_BAR_VEC_SIZE): Remove.
2668 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2670 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2672 Tweak last vectorlike_header change.
2673 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2674 vectorlike object on the free list. This is introduced to avoid
2675 some (but not all) pointer casting and aliasing problems, see
2676 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2677 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2679 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2681 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2683 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2684 been removed, so remove them here also.
2686 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2688 * doc.c (Fdocumentation): Handle new property
2689 dynamic-docstring-function to replace the old ad-advice-info.
2691 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2693 * fns.c (Qeql, hashtest_eq): Now static.

2702 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2704 Use same hash function for hashfn_profiler as for hash_string etc.
2705 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2706 * lisp.h (sxhash_combine): New inline function, with the contents
2707 of the old SXHASH_COMBINE.
2708 * profiler.c (hashfn_profiler): Use it, instead of having a
2709 special hash function containing a comparison that always yields 1.
2711 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2713 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2714 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2715 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2718 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2720 * image.c (xpm_make_color_table_h): Fix compiler error because
2721 make_hash_table changed.
2723 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2725 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2727 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2729 Use ad-hoc comparison function for the profiler's hash-tables.
2730 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2731 (make_log): Use them.
2732 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2733 call Fequal any more.

2742 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2743 (hash_lookup, hash_remove_from_table): Move assertion checking of
2744 hashfn result here. Check hash-equality before calling cmpfn.

2754 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2756 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2757 value of w32-scroll-lock-modifier is neither nil nor one of the
2758 known key modifiers. (Bug#12806)
2760 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2762 Shrink struct vectorlike_header to the only size field.
2763 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2765 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2766 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2767 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2768 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2769 information from the vector header. Adjust comment.

2780 (NEXT_IN_FREE_LIST): New macro.
2781 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2782 (Fmake_bool_vector): Likewise.
2783 (struct large_vector): New type to represent allocation unit for
2784 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2785 (large_vectors): Change type to struct large_vector.
2786 (allocate_vector_from_block): Simplify.
2787 (PSEUDOVECTOR_NBYTES): Replace with...
2788 (vector_nbytes): ...new function. Adjust users.

2795 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2796 * buffer.h (struct buffer): Add next member.
2797 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2799 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2800 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2801 (copy_hash_table): Adjust to match vector header change.
2802 * lread.c (defsubr): Use XSETPVECTYPE.
2803 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2804 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2805 (xvecsize): New command.
2807 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2809 * keyboard.c (event_to_kboard): Do not dereference
2810 frame_or_window field of SELECTION_REQUEST_EVENT
2811 and SELECTION_CLEAR_EVENT events (Bug#12814).
2812 * xterm.h (struct selection_input_event): Adjust comment.
2814 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2816 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2817 such as Scroll Lock, if the respective keys are treated as
2818 function keys, not as modifiers. This avoids destroying non-ASCII
2819 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2821 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2823 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2825 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2827 Restore some duplicate definitions (Bug#12814).
2828 This undoes part of the 2012-11-03 changes. Some people build
2829 with plain -g rather than with -g3, and they need the duplicate
2830 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2831 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2832 Define as macros, as well as as enums or as constants.
2834 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2836 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2837 to keypad keys (Bug#12816).
2839 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2841 Minor adjustments of recently-changed frame functions.
2842 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2843 known to be a frame (we're in the FRAMEP branch).
2844 * lisp.h (Qframep): Remove decl. frame.h declares this.
2845 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2846 since they're meant for Lisp fixnum values.
2848 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2850 * window.c (Fwindow_combination_limit): Revert to the only
2851 required argument and adjust docstring as suggested in
2852 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2853 by Martin Rudalics <rudalics@gmx.at>.
2855 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2857 Widely used frame validity and checking functions.
2858 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2859 * frame.c (decode_live_frame, decode_any_frame): New functions.
2860 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2861 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2862 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2863 (Fframe_pointer_visible_p): Use decode_any_frame.
2864 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2865 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2866 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2867 (Fframe_focus): Likewise. Allow zero number of arguments.
2869 (frame_buffer_list, frame_buffer_predicate): Remove.
2870 * lisp.h (frame_buffer_predicate): Remove prototype.
2871 * buffer.c (Fother_buffer): Use decode_any_frame.
2872 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2873 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2874 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2875 (Fclose_font, Ffont_info): Use decode_live_frame.
2876 * fontset.c (check_fontset_name): Likewise.
2877 * terminal.c (Fframe_terminal): Likewise.
2878 * w32fns.c (check_x_frame): Likewise.
2879 * window.c (Fminibuffer_window, Fwindow_at)
2880 (Fcurrent_window_configuration): Likewise.
2881 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2882 Likewise. Allow zero number of arguments. Adjust docstring.
2883 * dispnew.c (Fredraw_frame): Likewise.
2884 * xfaces.c (frame_or_selected_frame): Remove.
2885 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2886 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2887 (Fframe_face_alist): Use decode_live_frame.
2888 * xfns.c (check_x_frame): Likewise.
2890 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2892 * window.c (quad): New function.
2893 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2894 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2895 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2896 (Fwindow_line_height): Use it.
2897 (Fwindow_fringes): Use list3.
2898 (Fwindow_scroll_bars): Use list4.
2899 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2900 (Fwindow_combination_limit): Allow zero number of arguments.
2902 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2904 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2906 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2907 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2908 file descriptor 2 for standard error. (Bug#12805)
2910 2012-11-05 Chong Yidong <cyd@gnu.org>
2912 * process.c (wait_reading_process_output): Revert previous change.
2914 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2916 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2917 This removes code that has been obsolete since around 1990.
2918 * callproc.c (Fcall_process):
2920 * process.c (create_process):
2921 * term.c (dissociate_if_controlling_tty):
2922 Assume setsid exists.
2923 * callproc.c (child_setup): Assume setpgid exists and behaves as
2924 per POSIX.1-1988 or later.
2925 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2926 * emacs.c (shut_down_emacs):
2927 * sysdep.c (sys_suspend, init_foreground_group):
2928 Assume getpgrp behaves as per POSIX.1-1998 or later.
2929 * msdos.c (setpgrp): Remove.
2930 (tcgetpgrp, setpgid, setsid): New functions.
2931 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2932 * term.c (no_controlling_tty): Remove; unused.
2933 * w32proc.c (setpgrp): Remove.
2934 (setsid, tcgetpgrp): New functions.
2936 Simplify by assuming __fpending.
2937 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2938 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2939 Do not assume that __fpending's result fits in int.
2941 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2943 Remove EMACS_OUTQSIZE+sleep hack.
2944 * dispnew.c (update_frame_1): Remove hack for terminals slower
2945 than 2400 bps, which throttled Emacs by having it sleep.
2946 This code hasn't worked since at least 2007, when the multi-tty stuff
2947 was added, and anyway those old terminals are long dead.
2948 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2949 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2951 Fix data-loss with --version (Bug#9574).
2952 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2953 as we can't assume that emacs_strerror is initialized, and strerror
2954 is good enough here.
2955 (main): Invoke atexit earlier, to catch earlier instances of
2956 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2958 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2960 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2961 (keyDown): Remap keypad keys to X11 virtual key codes.
2963 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2965 Fix data-loss with --batch (Bug#9574).
2966 * emacs.c: Include <close-stream.h>.
2967 (close_output_streams): New function.
2968 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2969 and handles errors appropriately.
2970 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2973 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2974 The symptom is a diagnostic "GLib-WARNING **: In call to
2975 g_spawn_sync(), exit status of a child process was requested but
2976 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2977 waitpid(), so exit status can't be returned." The diagnostic
2978 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2979 The real bug is a race condition between Emacs and glib: Emacs
2980 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2981 so that glib can't find it. Work around the bug by invoking
2982 waitpid only on subprocesses that Emacs itself creates.
2983 * process.c (create_process, record_child_status_change):
2984 Don't use special value -1 in pid field, as the caller now must
2985 know the pid rather than having the callee infer it.
2986 The inference was sometimes incorrect anyway, due to another race.
2987 (create_process): Set new 'alive' member if child is created.
2988 (process_status_retrieved): New function.
2989 (record_child_status_change): Use it.
2990 Accept negative 1st argument, which means to wait for the
2991 processes that Emacs already knows about. Move special-case code
2992 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2993 processes that have already been waited for, by testing and
2994 clearing new 'alive' member.
2995 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2996 now does this internally.
2997 (handle_child_signal): Let record_child_status_change do all
2998 the work, since we do not want to reap all exited child processes,
2999 only the child processes that Emacs itself created.
3000 * process.h (Lisp_Process): New boolean member 'alive'.
3002 Omit duplicate definitions no longer needed with gcc -g3.
3003 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3004 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3005 Define only as macros. There's no longer any need to also define
3006 these symbols as enums or as constants, since we now assume
3007 gcc -g3 when debugging.
3009 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3011 * lisp.mk: Adjust comments to the fact that term/internal is now
3012 loaded from loadup.el.
3014 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3015 (msdos_fatal_signal): New function.
3016 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3019 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3020 for GCC versions before 4.
3021 (emacs_raise): Define to call msdos_fatal_signal.
3023 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3024 iterator when starting in the middle of a display or overlay
3027 2012-11-03 Chong Yidong <cyd@gnu.org>
3029 * process.c (wait_reading_process_output): Clean up the last
3032 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3034 * process.c (wait_reading_process_output): Avoid a race condition
3035 with SIGIO delivery (Bug#11536).
3037 2012-11-03 Chong Yidong <cyd@gnu.org>
3039 * buffer.c (cursor_type): Untabify docstring.
3041 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3043 * frame.h (struct frame): Drop can_have_scroll_bars member
3044 which is meaningless for a long time. Adjust comments.
3045 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3046 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3048 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3050 * window.c (decode_next_window_args): Update window arg after
3051 calling decode_live_window and so fix crash reported at
3052 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3053 by Juanma Barranquero <lekktu@gmail.com>.
3054 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3055 * font.c (Ffont_at): Likewise.
3057 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3059 * widget.c (resize_cb): New function.
3060 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3061 (EmacsFrameResize): Check if all is up to date before changing frame
3064 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3066 Implement backtrace output for fatal errors on MS-Windows.
3067 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3068 (BACKTRACE_LIMIT_MAX): New macro.
3069 (w32_backtrace): New function.
3070 (emacs_abort): Use w32_backtrace when the user chooses not to
3071 attach a debugger. Update the text of the abort dialog.
3073 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3075 Window-related stuff cleanup here and there.
3076 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3077 Use decode_any_window.
3078 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3079 * xdisp.c (Fformat_mode_line): Likewise.
3080 * font.c (Ffont_at): Use decode_live_window.
3081 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3082 * window.c (decode_next_window_args): Likewise.
3083 (decode_any_window): Remove static.
3084 * window.h (decode_any_window): Add prototype.
3085 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3086 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3089 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3091 Remove pad from struct input_event.
3092 * termhooks.h (struct input_event): Remove padding field.
3094 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3095 member is never cons for a long time. Adjust comment.
3096 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3097 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3098 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3099 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3101 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3103 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3105 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3107 Fix crash when using Emacs as commit editor for git (Bug#12697).
3108 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3109 and it is configured in conf_post.h.
3110 (Fcall_process): Don't invoke both setsid and setpgid; the former
3111 is enough, if it exists.
3112 * callproc.c (Fcall_process, child_setup):
3113 * process.c (create_process): Use setpgid.
3114 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3116 * dispnew.c (init_display): Initialize the foreground group
3117 if we are running a tty display.
3118 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3119 * lisp.h (init_foreground_group): New decl.
3120 * sysdep.c (inherited_pgroup): New static var.
3121 (init_foreground_group, tcsetpgrp_without_stopping)
3122 (narrow_foreground_group, widen_foreground_group): New functions.
3123 (init_sys_modes): Narrow foreground group.
3124 (reset_sys_modes): Widen foreground group.
3126 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3128 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3130 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3132 * minibuf.c (read_minibuf): Restore current buffer since
3133 choose_minibuf_frame calling Fset_frame_selected_window may
3134 change it (Bug#12766).
3136 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3138 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3140 2012-10-30 Kenichi Handa <handa@gnu.org>
3142 * font.c (Ffont_at): If WINDOW is specified and it is not
3143 displaying the current buffer, signal an error.
3145 2012-10-29 Daniel Colascione <dancol@dancol.org>
3147 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3148 In preparation for fixing bug#12739, move these functions from
3151 * coding.h, coding.c: ... to here, and compile them only when
3152 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3153 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3155 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3157 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3158 (timer_loop, getitimer, setitimer): Use it instead of
3159 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3161 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3164 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3166 * nsterm.m (NO_APPDEFINED_DATA): New define.
3167 (last_appdefined_event_data): New variable
3168 (last_appdefined_event): Remove.
3169 (ns_select): Initialize t from last_appdefined_event_data instead
3170 of [last_appdefined_event data1].
3171 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3172 remove last_appdefined_event (Bug#12698).
3174 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3176 * frame.c (x_set_font): Catch internal error.
3178 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3180 Avoid overflow in w32 implementation of interval timers.
3181 When possible, for ITIMER_PROF count only times the main thread
3183 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3184 'volatile ULONGLONG' types. All the other data which was
3185 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3186 (GetThreadTimes_Proc): New typedef.
3187 (w32_get_timer_time): New function, returns a suitable time value
3189 (timer_loop): Enter critical section when accessing ULONGLONG
3190 values of the itimer_data struct, as these accesses are no longer
3191 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3192 Remove unused variable.
3193 (init_timers): Initialize s_pfn_Get_Thread_Times.
3194 (start_timer_thread): Don't assign itimer->caller_thread here.
3195 (getitimer): Assign itimer->caller_thread here.
3196 (setitimer): Always call getitimer to get the value of ticks_now.
3197 (sys_spawnve): Avoid compiler warning about format mismatch.
3199 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3201 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3202 mouse movement events if the menu bar is active. This avoids
3203 producing a busy "hour-glass" cursor by Windows if the mouse
3204 pointer is positioned over a tooltip shown for some menu item.
3206 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3208 Don't assume process IDs fit in int.
3209 * emacs.c (shut_down_emacs) [!DOS_NT]:
3210 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3211 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3212 Use pid_t, not int, to store process IDs, as 'int'
3213 is not wide enough on a few platforms (e.g., AIX and IRIX).
3215 2012-10-23 Kenichi Handa <handa@gnu.org>
3217 The following change is to make face-font-rescale-alist work
3218 correctly for non-ASCII fonts.
3220 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3221 (font_open_for_lface): Handle Vface_font_rescale_alist.
3223 2012-10-23 Chong Yidong <cyd@gnu.org>
3225 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3227 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3229 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3231 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3233 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3236 2012-10-21 Glenn Morris <rgm@gnu.org>
3238 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3240 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3242 Port to OpenBSD 5.1.
3243 * frame.c (Fmouse_position, Fmouse_pixel_position):
3244 * xdisp.c (produce_stretch_glyph):

3722 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3723 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3724 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3725 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3726 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3727 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3728 now a supported configuration.
3730 * Makefile.in: consolidate image variables into LIBIMAGE; add
3731 W32_OBJ and W32_LIBS. Compile new files.
3734 (_DebPrint) declare tracing facility for W32 debugging. We need
3735 to unify tracing later.
3737 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3738 unconditional use of W32 Unicode functions. Cygwin runs only on
3739 100% Unicode operating systems.
3741 * cygw32.c: New file. Define Cygwin-specific facilities.
3742 (Fcygwin_convert_path_to_windows)
3743 (Fcygwin_convert_path_from_windows): New user functions for
3744 accessing Cygwin path-munging routines.
3746 * cygw32.h: New file.
3747 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3748 UTF-16LE strings temporarily inside non-Lisp-visible string
3751 (w32_strerror): Just what it says on the tin.
3753 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3754 also run for Cygwin; both systems have the same problem with using
3755 GUI facilities in a forked child. Also call syms_of_cygw32,
3756 syms_of_w32select in correct places.
3758 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3759 needs fork-then-exec for daemon launching.
3761 * font.h: Include frame.h.
3763 * image.c: Use the image library cache machinery only when we're
3764 compiling for native WINDOWSNT; Cygwin can use shared libraries
3765 like any other Unixlike system.
3767 * keyboard.c: Clarify a comment regarding the input loop.
3769 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3770 functions directly instead of trying to detect at runtime that our
3771 host operating system supports them. We make this change for two
3772 reasons: Cygwin lacks support for the multibyte character
3773 conversion functions used by the legacy menu code, and Cygwin
3774 never needs to rely on non-Unicode APIs.
3776 * unexw32.c (hinst): Declare extern.
3778 * w32.c: Change header order;
3779 (w32_strerror): Move to w32fns.c because we need it for
3780 non-WINDOWSNT builds.
3782 * w32.h: Add #error macro to make sure we don't include w32.h for
3783 Cygwin builds. Remove w32select declarations.
3785 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3786 w32fns.c. w32console.c is WINDOWSNT-only.
3788 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3789 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3791 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3792 (w32_major_version, w32_minor_version, w32_build_number)
3793 (os_subtype, sound_type): Define here
3794 (w32_defined_color): Make color parameter const for consistency
3795 with other _defined_color functions.
3796 (w32_createwindow): Unconditionally call w32_init_class instead of
3797 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3798 through the code is complex and unnecessary because class
3799 registration is practically free.
3800 (w32_name_of_message): New EMACSDEBUG-only function.
3801 (Fset_message_beep): Move here
3802 (Fx_open_connection): Require that the display name for Windows be
3803 "w32" for consistency, emacsclient disambiguation, and maybe, one
3804 day, multi-window-system support.
3805 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3806 Cygwin files for W32 GUI facilities, since these clearly don't
3807 expect Cygwin names.
3808 (_DebPrint): Define.
3809 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3810 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3811 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3812 (w32_last_error): Remove.
3814 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3816 * w32heap.c (syspage_mask): Declare here.
3817 (cache_system_info): Remove.
3819 * w32inevt.c (faked_key): Define globally, not statically.
3820 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3821 (w32_console_toggle_lock_key): Move to w32fns.c.
3823 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3825 * w32proc.c (_DebPrint): Move to w32fns.c.
3826 * w32select.c: Include string.h, stdio.h for Cygwin.
3827 * w32select.h: New File.
3829 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3831 (w32_message_fd): New variable. Under Cygwin, holds the file
3832 descriptor the system used to tell us about pending thread
3835 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3836 that prevented compilation under non-WINDOWSNT systems.
3838 (w32_initialize): Open /dev/windows and assign it to
3839 w32_message_fd. Provide w32 feature.
3841 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3842 (WM_EMACS_INPUT_READY): add.
3843 (prepend_msg, w32_message_fd): Declare globally.
3846 (keyboard_handle): Use only when WINDOWSNT.
3847 (notify_msg_ready): New function. Posts a message to the main
3848 thread's message queue under CYGWIN, which wakes up the main
3849 thread from select(2) by making the /dev/windows file descriptor
3850 ready. Under WINDOWSNT, it sets an event the same way the old
3853 (post, prepend_msg): Actually call notify_msg_ready instead of
3854 setting the input event directly.
3856 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3858 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3859 but it still has blocs in it, don't return it to the system,
3860 instead of aborting. (Bug#12402)
3862 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3864 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3866 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3867 MAC_OS_X_VERSION_10_6.
3868 (syms_of_nsterm): Remove comment about Panther and above for
3870 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3871 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3872 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3874 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3875 MAC_OS_X_VERSION_10_4.
3877 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3878 MAC_OS_X_VERSION_10_2.
3880 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3882 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3883 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3885 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3886 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3887 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3888 Remove ns_in_resize check.
3889 (ns_clear_frame_area): Remove resize handle code.
3891 * nsfns.m (ns_in_resize): Remove.
3892 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3893 Remove ns_in_resize check.
3895 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3897 Improve sys_siglist detection.
3898 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3899 defined as a macro, as is done in Solaris.
3900 (sys_siglist_entries): New macro.
3901 (save_strsignal): Use it.
3902 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3903 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3905 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3907 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3908 fullscreen/Fullscreen.
3910 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3911 tobar_height is new.
3913 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3914 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3915 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3916 (windowDidResize:): Check for correct window if old style fullscreen.
3917 Capitalize word in comment. Remove incorrect comment.
3918 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3919 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3920 error in drawing background.
3921 (toggleFullScreen:): Remove comment. Rearrange calls.
3922 Set toolbar values to zero, save old height in tobar_height.
3923 Restore tool bar height when leaving fullscreen.
3924 (canBecomeMainWindow): New function.
3926 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3928 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3930 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3932 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3934 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3935 that time stamps of directories could also be changed.
3936 Don't request the too broad GENERIC_WRITE, only the more restrictive
3937 FILE_WRITE_ATTRIBUTES access rights.
3939 * fileio.c (Fset_file_times): Special-case ignoring errors for
3940 directories only on MSDOS, not on MS-Windows.
3942 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3944 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3946 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3948 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3949 see whether CreateFile failed.
3951 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3953 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3954 to avoid similar races.
3955 * keyboard.c (pending_signals): Now bool, not int.
3957 Port timers to OpenBSD, plus check for timer failures.
3958 OpenBSD problem reported by Han Boetes.
3959 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3961 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3962 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3963 like OpenBSD, which has timer_settime but does not declare it.
3964 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3965 whether to use itimerspec-related primitives. All uses of
3966 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3968 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3970 * profiler.c (handle_profiler_signal): Fix a malloc race
3971 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3973 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3975 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3977 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3979 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3980 consistent with the change in return value of 'safe_strsignal'.
3982 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3984 Prefer plain 'static' to 'static inline' (Bug#12541).
3985 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3986 (bidi_set_sor_type, bidi_push_embedding_level)
3987 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3988 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3989 (bidi_cache_search, bidi_cache_ensure_space)
3990 (bidi_cache_iterator_state, bidi_cache_find)
3991 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3992 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3993 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3994 Now 'static', not 'static inline'.
3996 Count overruns when profiling; change units to ns.
3997 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3998 Give extra weight to samples after overruns, to attempt to count
3999 the time more accurately.
4000 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4001 the underlying primitives nominally do ns.
4002 (Fprofiler_cpu_start): Document the change. Mention that
4003 the sampling intervals are only approximate.
4005 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4007 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4009 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4010 case for the special 0 coding-system.
4012 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4013 (Fmake_overlay): Remove redundant tests.
4014 (fix_start_end_in_overlays): Remove redundant recentering.
4016 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4018 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4019 Update dependencies.
4021 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4023 Fix a malloc race condition involving strsignal.
4024 A signal can arrive in the middle of a malloc, and Emacs's signal
4025 handler can invoke strsignal, which can invoke malloc, which is
4026 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4027 Fix it by altering the signal handler so that it does not invoke
4029 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4030 * process.c (status_message): Use const pointer, in case strsignal
4031 is #defined to safe_strsignal.
4032 * sysdep.c (sys_siglist, init_signals): Always define and
4033 initialize a substitute sys_siglist if the system does not define
4034 one, even if HAVE_STRSIGNAL.
4035 (safe_strsignal): Rename from strsignal. Always define,
4036 using sys_siglist. Return a const pointer.
4037 * syssignal.h (safe_strsignal): New decl.
4038 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4040 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4042 * w32proc.c (timer_loop): Fix code that waits for timer
4043 expiration, to avoid high CPU usage.
4045 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4047 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4048 (sweep_weak_table): Remove redundant prototypes.
4050 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4052 * emacs.c: Move the inclusion of TERM_HEADER after including
4053 windows.h on WINDOWSNT. This avoids compilation problems with
4056 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4058 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4059 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4060 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4061 as the previous version used 'void *'.
4063 * ralloc.c (ROUNDUP): Fix last change.
4064 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4067 * w32proc.c <disable_itimers>: New static flag.
4068 (init_timers): Initialize it to zero, after creating the critical
4069 sections used by the timer threads.
4070 (term_timers): Set to 1 before deleting the critical sections.
4071 (getitimer, setitimer): If disable_itimers is non-zero, return an
4072 error indication without doing anything. Reported by Fabrice
4073 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4074 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4076 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4079 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4080 term_ntproc after all the other bookkeeping, to get timers working
4081 as long as possible.
4083 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4085 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4086 Suggested by Juri Linkov in
4087 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4089 Prefer plain 'static' to 'static inline' (Bug#12541).
4090 With static functions, modern compilers inline pretty well by
4091 themselves; advice from programmers often hurts as much as it helps.
4092 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4093 this change shrinks the text size of the Emacs executable by 1.1%
4094 without affecting CPU significantly in my benchmark.

4180 * dired.c (directory_files_internal, Ffile_attributes):
4183 * frame.c (x_report_frame_params): Port better to wider ints.
4184 Do not assume that EMACS_UINT is the same width as uprintmax_t,

4388 (handle_profiler_signal): Rename from sigprof_handler_1,
4389 for consistency with other handlers. Do not check whether
4390 cpu_log is a hash-table if garbage collecting, since it

4393 for consistency with other handlers.
4394 (setup_cpu_timer): New function, with much of what used to be in
4395 Fprofiler_cpu_start. Check for out-of-range argument.
4396 Prefer timer_settime if available, and prefer
4397 thread cputime clocks, then process cputime clocks, then
4398 monotonic clocks, to the old realtime clock. Use make_timeval
4399 to round more-correctly when falling back to setitimer.
4400 (Fprofiler_cpu_start): Use it.
4401 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4408 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4409 in profiler.c, since sysdep.c now uses it.
4411 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4467 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4468 Since this stuff is now private to charset.c, there's no need for
4469 a public macro and no need to inline by hand.

4543 (sys_kill): Improve commentary.
4545 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4546 consistency with a signature of a signal handler. All callers
4548 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4549 install term_ntproc as a signal handler for SIGABRT, as that
4550 should be done by the dumped Emacs.

4624 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4625 * callproc.c: Include syswait.h.
4627 gnutls.c, gtkutil.c: Use bool for boolean.
4628 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)

4645 Use bool for boolean.
4646 * gtkutil.c (xg_update_frame_menubar):
4647 * xmenu.c (update_frame_menubar):
4648 Return void, not int, since caller ignores return value.

4652 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4654 * makefile.w32-in (BLOCKINPUT_H): Remove.

4671 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4673 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4674 fatal_error_backtrace.
4676 * w32proc.c (sys_kill): Undo last change: don't do anything when
4677 invoked to deliver SIGABRT to our own process. This is now
4678 handled by emacs_raise.
4680 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4682 * w32term.c (w32_read_socket): Remove leftover reference to
4683 interrupt_input_pending.
4685 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4687 Do not use SA_NODEFER.
4688 Problem reported by Dani Moncayo in
4689 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4691 * sysdep.c (emacs_abort): Do not reset signal handler.
4692 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4693 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4694 wanted even on POSIXish hosts, and it doesn't work on Windows.
4696 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4698 * xterm.c (x_term_init): Call fixup_locale before and after calling
4699 gtk_init (Bug#12392).
4701 2012-09-23 Chong Yidong <cyd@gnu.org>
4703 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4704 Vdynamic_library_alist.
4706 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4707 (Fgnutls_available_p): Caller changed.
4709 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4710 (Flibxml_parse_xml_region): Likewise.
4712 * dispextern.h (struct image_type): Remove arg from init function.
4714 * image.c (Finit_image_library, lookup_image_type)
4715 (define_image_type): Remove now-unneeded second arg.
4716 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4717 (init_tiff_functions, init_gif_functions, init_svg_functions):
4718 Arglist and w32_delayed_load calling convention changed.
4719 (gs_type): Remove init_gs_functions; there is no such function.
4720 (valid_image_p, make_image): Fix caller to lookup_image_type.
4722 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4724 Simplify and avoid signal-handling races (Bug#12471).
4726 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4727 Avoid recursive loop if there's a fatal error in the function itself.
4728 * atimer.c (pending_atimers):
4729 * blockinput.h: Don't include "atimer.h"; no longer needed.
4730 (interrupt_input_pending): Remove. All uses removed.
4731 pending_signals now counts both atimers and ordinary interrupts.
4732 This is less racy than having three separate pending-signal flags.
4733 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4735 Rename from their upper-case counterparts BLOCK_INPUT,
4736 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4737 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4738 This makes it easier to access volatile variables more accurately.
4739 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4740 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4741 that's more reliable if the code is buggy and sets
4742 interrupt_input_blocked to a negative value. All uses changed.
4743 * atimer.c (deliver_alarm_signal):
4744 Remove. No need to deliver this to the parent; any thread can
4745 handle this signal now. All uses replaced by underlying handler.
4746 * atimer.c (turn_on_atimers):
4747 * dispnew.c (handle_window_change_signal):
4748 * emacs.c (handle_danger_signal):
4749 * keyboard.c (kbd_buffer_get_event):
4750 Don't reestablish signal handler; not needed with sigaction.
4751 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4753 Rework to avoid unnecessary accesses to volatile variables.
4754 (UNBLOCK_INPUT_TO): Now a function.
4755 (totally_unblock_input, unblock_input): New decls.
4756 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4757 (init_data): Remove. Necessary stuff now done in init_signal.
4758 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4759 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4760 (fatal_error_code): Remove; no longer needed.
4761 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4762 it doesn't always backtrace. All uses changed. No need to reset
4763 signal to default, since sigaction and/or die does that for us now.
4764 Use emacs_raise (FOO), not kill (getpid (), FOO).
4765 (main): Check more-accurately whether we're dumping.
4766 Move fatal-error setup to sysdep.c
4767 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4768 * gtkutil.c (xg_get_file_name, xg_get_font):
4769 Remove no-longer-needed signal-mask manipulation.
4770 * keyboard.c, process.c (POLL_FOR_INPUT):
4771 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4772 * keyboard.c (read_avail_input): Remove.
4773 All uses replaced by gobble_input.
4774 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4775 (kbd_buffer_store_event_hold, gobble_input):
4776 (record_asynch_buffer_change) [USABLE_SIGIO]:
4777 (store_user_signal_events):
4778 No need to mess with signal mask.
4779 (gobble_input): If blocking input and there are terminals, simply
4780 set pending_signals to 1 and return. All hooks changed to not
4781 worry about whether input is blocked.
4782 (process_pending_signals): Clear pending_signals before processing
4783 them, in case a signal comes in while we're processing.
4784 By convention callers now test pending_signals before calling us.
4785 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4786 New functions, to support changes to blockinput.h.
4787 (handle_input_available_signal): Now extern.
4788 (reinvoke_input_signal): Remove. All uses replaced by
4790 (quit_count): Now volatile, since a signal handler uses it.
4791 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4792 All callers changed. Block SIGINT only if not already blocked.
4793 Clear sigmask reliably, even if Fsignal returns, which it can.
4794 Omit unnecessary accesses to volatile var.
4795 (quit_throw_to_read_char): No need to restore sigmask.
4796 * keyboard.c (gobble_input, handle_user_signal):
4797 * process.c (wait_reading_process_output):
4798 Call signal-handling code rather than killing ourselves.
4799 * lisp.h: Include <float.h>, for...
4800 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4801 (pending_signals): Now volatile.
4802 (syms_of_data): Now const if IEEE floating point.
4803 (handle_input_available_signal) [USABLE_SIGIO]:
4804 (terminate_due_to_signal, record_child_status_change): New decls.
4805 * process.c (create_process): Avoid disaster if memory is exhausted
4806 while we're processing a vfork, by tightening the critical section
4808 (send_process_frame, process_sent_to, handle_pipe_signal)
4809 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4811 (send_process): No need for setjmp/longjmp any more, since the
4812 SIGPIPE stuff is now gone. Instead, report an error if errno
4814 (record_child_status_change): Now extern. PID and W are now args.
4815 Return void, not bool. All callers changed.
4816 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4817 Remove. All uses removed. This bug should be fixed now in a
4819 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4820 and record the child status change directly. This avoids the
4821 need to futz with the signal mask.
4822 (process_fatal_action): Move here from emacs.c.
4823 (emacs_sigaction_flags): New function, containing
4824 much of what used to be in emacs_sigaction_init.
4825 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4826 caught by emacs, to make races less likely.
4827 (deliver_process_signal): Rename from handle_on_main_thread.
4829 (BACKTRACE_LIMIT_MAX): Now at top level.
4830 (thread_backtrace_buffer, threadback_backtrace_pointers):
4832 (deliver_thread_signal, deliver_fatal_thread_signal):
4833 New functions, for more-accurate delivery of thread-specific signals.
4834 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4835 (deliver_arith_signal): Handle in this thread, not
4836 in the main thread, since it's triggered by this thread.
4837 (maybe_fatal_sig): New function.
4838 (init_signals): New arg DUMPING so that we can be more accurate
4839 about whether we're dumping. Caller changed.
4840 Treat thread-specific signals differently from process-general signals.
4841 Block all signals while handling fatal error; that's safer.
4842 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4844 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4845 Ignore SIGPIPE unless batch.
4846 (emacs_backtrace): Output backtrace for the appropriate thread,
4847 which is not necessarily the main thread.
4848 * syssignal.h: Include <stdbool.h>.
4849 (emacs_raise): New macro.
4850 * xterm.c (x_connection_signal): Remove; no longer needed
4851 now that we use sigaction.
4852 (x_connection_closed): No need to mess with sigmask now.
4853 (x_initialize): No need to reset SIGPIPE handler here, since
4854 init_signals does this for us now.
4856 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4858 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4859 background rect may be larger (Bug#12245).
4861 2012-09-23 Chong Yidong <cyd@gnu.org>
4863 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4865 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4867 * .gdbinit: Just stop at fatal_error_backtrace.
4868 See Stefan Monnier's request in
4869 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4870 Remove no-longer-used query of system type.
4872 2012-09-22 Chong Yidong <cyd@gnu.org>
4874 * search.c (Freplace_match): Doc fix (Bug#12325).
4876 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4878 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4879 (Fline_end_position): Doc fix.
4881 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4883 2012-09-22 Chong Yidong <cyd@gnu.org>
4885 * dispextern.h (struct image_type): Add new slot, storing a type
4886 initialization function.
4888 * image.c (define_image_type): Call the image initializer function
4889 if it is defined. Arguments and return value changed.
4890 (valid_image_p, make_image): Callers changed.
4891 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4892 (gif_type, imagemagick_type, svg_type, gs_type):
4893 Add initialization functions.
4894 (Finit_image_library): Call lookup_image_type.
4895 (CHECK_LIB_AVAILABLE): Macro deleted.
4896 (lookup_image_type): Call define_image_type here, rather than via
4897 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4898 (syms_of_image): Move define_image_type calls for xbm_type and
4899 pbm_type to lookup_image_type.
4901 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4903 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4904 'idle_timers' from here ...
4905 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4906 lists, to avoid infloops when the timer does something stupid,
4907 like reinvoke itself with the same or smaller time-out.
4910 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4912 * window.c (Fsplit_window_internal): Handle only Qt value of
4913 Vwindow_combination_limit separately.
4914 (Qtemp_buffer_resize): New symbol.
4915 (Vwindow_combination_limit): New default value.
4918 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4920 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4921 the new overlay string. (Bug#10159)
4923 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4925 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4926 or that fprintf is async-signal-safe. POSIX doesn't require
4929 2012-09-22 Chong Yidong <cyd@gnu.org>
4931 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4934 2012-09-22 Kenichi Handa <handa@gnu.org>
4936 * composite.c (composition_reseat_it): Handle the case that a
4937 grapheme cluster is not covered by a single font (Bug#12352).
4939 2012-09-21 Chong Yidong <cyd@gnu.org>
4941 * image.c (define_image_type): Avoid adding duplicate types to
4942 image_types (Bug#12463). Suggested by Jörg Walter.
4944 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4946 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4947 (print_load_command_name): Add case LC_DATA_IN_CODE.
4948 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4950 2012-09-21 Glenn Morris <rgm@gnu.org>
4952 * eval.c (Frun_hook_with_args_until_success)
4953 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4955 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4957 * fileio.c (Ffile_selinux_context): Only call freecon when
4958 lgetfilecon succeeded.
4959 (Fset_file_selinux_context): Likewise. (Bug#12444)
4961 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4963 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4964 reordering, locate the cursor by calling set_cursor_from_row; if
4965 that fails, clear the desired glyph matrix before returning a
4966 failure indication to the caller. Fixes leaving garbled display
4967 when fast scrolling with a down-key. (Bug#12403)
4968 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4969 scrolling through multibyte text.
4971 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4973 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4974 calling mark_vectorlike since that's the one that marks the window.
4975 (mark_discard_killed_buffers): Mark the final cdr.
4976 * window.h (struct window): Move prev/next_buffers to the
4977 non-standard fields.
4978 * window.c (make_window): Initialize prev/next_buffers manually.
4980 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4982 Omit unused arg EXPECTED from socket hooks.
4983 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4984 * nsterm.m (ns_term_init):
4985 * termhooks.h (struct terminal.read_socket_hook):
4986 * w32inevt.c (w32_console_read_socket):
4987 * w32term.c (w32_read_socket):
4988 * xterm.c (XTread_socket):
4989 Omit unused arg EXPECTED. All callers changed.
4990 (store_user_signal_events): Return void, not int, since callers no
4991 longer care about the return value. All uses changed.
4993 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4995 * w32gui.h (XParseGeometry): Do not declare.
4997 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4999 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5000 Ignore 'expected'. See Eli Zaretskii in
5001 <http://bugs.gnu.org/12471#8> (last line).
5003 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5004 (XParseGeometry): Now static. Substitute extremal values for
5005 values that are out of range.
5007 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5009 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5011 * nsfns.m (XParseGeometry): Remove.
5012 (Fx_create_frame): Call x_set_offset to correctly interpret
5013 top_pos in geometry.
5015 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5016 (Fx_parse_geometry): If there is a space in string, call
5017 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5019 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5021 * search.c (scan_buffer): Use character positions in calls to
5022 region_cache_forward and region_cache_backward, not byte
5023 positions. (Bug#12196)
5025 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5026 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5028 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5029 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5030 emacs_blocked_malloc, now deleted.
5032 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5034 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5035 The workaround was for improving performance on Solaris 2.4, but
5036 is getting in the way now. Emacs will still work if someone is
5037 still running Solaris 2.4 in a museum somewhere; Sun dropped
5038 support for Solaris 2.4 in 2003.
5039 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5040 * process.c (create_process) [HAVE_WORKING_VFORK]:
5041 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5042 since Emacs no longer uses vfork on that platform.
5044 2012-09-17 Glenn Morris <rgm@gnu.org>
5046 * emacs.c: Use COPYRIGHT.
5048 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5050 Remove configure's --without-sync-input option (Bug#12450).
5051 When auditing signal-handling in preparation for cleaning it up,
5052 I found that SYNC_INPUT has race conditions and would be a real
5053 pain to fix. Since it's an undocumented and deprecated
5054 configure-time option, now seems like a good time to remove it.
5055 Also see <http://bugs.gnu.org/11080#16>.
5056 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5057 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5058 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5059 (malloc_hysteresis):
5060 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5061 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5062 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5063 (dont_register_blocks, bytes_used_when_reconsidered)
5064 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5065 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5066 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5067 Remove. All uses removed.
5068 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5069 implementation, one that depends on whether the new macro
5070 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5072 * atimer.c (run_timers, handle_alarm_signal):
5073 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5074 (handle_async_input, process_pending_signals)
5075 (handle_input_available_signal, init_keyboard):
5076 * nsterm.m (ns_read_socket):
5077 * process.c (wait_reading_process_output):
5078 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5079 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5081 * xterm.c (XTread_socket):
5083 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5084 * eval.c (handling_signal): Remove. All uses removed.
5085 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5086 All uses replaced with the SYNC_INPUT version.
5087 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5089 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5092 * font.c (Ffont_shape_gstring): Remove unused local.
5094 2012-09-16 Glenn Morris <rgm@gnu.org>
5096 * Makefile.in (clean): No longer run nextstep's clean.
5098 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5100 (ns-app): Move here from ns.mk, and simplify.
5101 (clean): Simplify nextstep entry.
5102 * ns.mk: Remove file.
5104 2012-09-17 Kenichi Handa <handa@gnu.org>
5106 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5107 not covert the last few charactes.
5109 2012-09-16 Kenichi Handa <handa@gnu.org>
5111 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5112 here, but just check the validity of glyphs in the glyph-string.
5114 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5116 * window.c (Fwindow_parameter, Fset_window_parameter):
5117 Accept any window as argument (Bug#12452).
5119 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5121 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5122 to ns_term_init to avoid memory leak.
5124 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5125 explicit retain/release.
5126 (ns_term_init): Only allow one display. Initialize outerpool and
5129 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5131 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5132 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5133 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5134 the Microsoft problem in a different way, by altering ../nt/config.nt.
5136 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5151 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5152 by lisp.h. This completes removal of setjmp.h inclusion
5153 erroneously announced in the previous commit. (Bug#12446)
5155 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5158 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5159 not defined as a macro. The latter happens on MS-Windows.
5162 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5164 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5165 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5166 Some instances of '#include <setjmp.h>' removed, if the
5167 only reason for the instance was because "lisp.h" was included.
5168 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5169 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5170 and _longjmp with the new symbols. Emacs already uses _setjmp if
5171 available, so this change affects only POSIXish hosts that have
5172 sigsetjmp but not _setjmp, such as some versions of Solaris and
5173 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5174 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5175 (png_load_body) [HAVE_PNG]:
5176 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5177 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5178 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5179 since PNG requires jmp_buf. This is the only exception to the
5180 general rule that we now use sys_setjmp and sys_longjmp.
5181 This exception is OK since this code does not change the signal
5182 mask or longjmp out of a signal handler.
5184 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5186 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5187 Include "syssignal.h", for 'main_thread'.
5189 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5191 Avoid out-of-range marker position (Bug#12426).
5192 * insdel.c (replace_range, replace_range_2):
5193 Adjust markers before overlays, as suggested by comments.
5194 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5195 Remove redundant check before calling offset_intervals.
5197 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5199 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5200 current buffer (Bug#12387).
5202 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5204 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5206 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5208 Use a more backwards-compatible timer format (Bug#12430).
5209 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5210 vector element, not from the 4th, since PSECS is now at the end.
5211 (Fcurrent_idle_time): Doc fix.
5213 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5215 Function to mark objects and remove killed buffers at once.
5216 * alloc.c (discard_killed_buffers): Rename to ...
5217 (mark_discard_killed buffers) ... new name. Add marking
5218 of remaining objects. Fix comment. Adjust users.
5219 (mark_object): Do not touch frame buffer lists here.
5220 * frame.c (delete_frame): Reset frame buffer lists here.
5222 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5224 Better workaround for GNOME bug when --enable-gcc-warnings.
5225 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5226 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5227 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5229 Simplify SIGIO usage (Bug#12408).
5230 The code that dealt with SIGIO was crufty and confusing, e.g., it
5231 played tricks like "#undef SIGIO" but these tricks were not used
5232 consistently. Simplify mostly by not #undeffing standard symbols,
5233 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5234 or not as we please) rather than "defined SIGIO" (standard symbol
5235 that we probably shouldn't #undef).
5236 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5237 Modules that need it can include it.
5238 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5239 * dispextern.h (ignore_sigio): New decl.
5240 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5241 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5242 * emacs.c (shut_down_emacs):
5243 * keyboard.c (kbd_buffer_store_event_hold):
5244 Use ignore_sigio rather than invoking 'signal' directly.
5245 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5247 (FIONREAD, SIGIO): Do not #undef.
5248 (tty_read_avail_input): Use #error rather than a syntax error.
5249 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5250 for I_PIPE, used by SETUP_SLAVE_PTY.
5251 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5252 * sysdep.c (croak): Remove; no longer needed. This bit of
5253 temporary code, with Fred N. Fish's comment that it's temporary,
5254 has been in Emacs since at least 1992!
5255 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5256 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5257 * syssignal.h (croak): Remove decl.
5258 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5259 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5260 now that we're termios-only.
5261 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5262 * term.c (dissociate_if_controlling_tty): Use #error rather than
5265 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5266 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5267 to work around GNOME bug 683906.
5268 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5269 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5270 This works around GCC bug 54561.
5272 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5274 More fixes for 'volatile' and setjmp/longjmp.
5275 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5276 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5277 (png_load_body) [HAVE_PNG]:
5278 (jpeg_load_body) [HAVE_JPEG]:
5279 New function, with most of the old parent function's body.
5280 (png_load) [HAVE_PNG]:
5281 (jpeg_load) [HAVE_JPEG]:
5282 Invoke the new function, to avoid longjmp munging our locals.
5283 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5284 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5285 longjmp is passed 2, as the C standard doesn't guarantee this.
5286 Instead, store the failure code into mgr->failure_code.
5288 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5290 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5291 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5292 (syms_of_keyboard): Remove support for unread-command-char.
5294 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5296 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5297 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5298 violation. (Bug#12426)
5300 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5302 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5304 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5306 * eval.c: Add `inhibit-debugger'.
5307 (Qinhibit_debugger): New symbol.
5308 (call_debugger): Bind it instead of Qdebug_on_error.
5309 (maybe_call_debugger): Test Vinhibit_debugger.
5310 (syms_of_eval): Define inhibit-debugger.
5311 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5312 (syms_of_xdisp): Remove inhibit-debug-on-message.
5314 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5316 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5317 If a nonvolatile local variable is written before a _longjmp to
5318 the frame containing the variable, and is read after the _longjmp,
5319 the value read is indeterminate. Some local variables of type
5320 'struct handler' and 'struct catchtag' are used in this way, so
5321 mark each of their slots as volatile if the slot can be set before
5322 _longjmp and read afterwards.
5323 * lisp.h (struct handler): var and chosen_clause are now volatile.
5324 (struct catchtag): val, next, and pdlcount are now volatile.
5326 * bidi.c (bidi_push_it, bidi_pop_it):
5327 * fns.c (copy_hash_table):
5328 * image.c (define_image_type):
5329 * keyboard.c (kbd_buffer_store_event_hold):
5330 * process.c (Fprocess_send_eof):
5331 * xfaces.c (x_create_gc) [HAVE_NS]:
5332 * xgselect.c (xg_select):
5333 Prefer assignment to memcpy when either will do.
5335 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5336 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5337 time an item is removed. No need to mark this function 'inline';
5338 the compiler knows better than we do.
5340 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5342 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5343 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5344 to change_frame_size (Bug#12388).
5345 (windowDidResize:): Pass YES to updateFrameSize.
5347 * nsterm.h: Add delay parameter to updateFrameSize.
5349 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5351 Discard killed buffers from deleted window and frame objects.
5352 This reduces an amount of references to killed buffers and
5353 helps GC to reclaim them faster.
5354 * alloc.c (discard_killed_buffers): New function.
5355 (mark_object): Use it for deleted windows and frames.
5356 (mark_object): If symbol's value is set up for a killed buffer
5357 or deleted frame, restore its global binding.
5358 * data.c (swap_in_global_binding): Add GC notice.
5359 (swap_in_symval_forwarding): Use convenient set_blv_where.
5360 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5361 * window.h: ... to here.
5363 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5365 Convenient macro to check whether the buffer is live.
5366 * buffer.h (BUFFER_LIVE_P): New macro.
5367 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5368 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5370 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5372 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5373 composition cases (Bug#12364).
5375 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5376 overhang of succeeding glyphs overlapping box cursor.
5378 * w32term.c (x_draw_glyph_string): Likewise.
5380 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5382 Simplify, document, and port floating-point (Bug#12381).
5383 The porting part of this patch fixes bugs on non-IEEE platforms
5384 with frexp, ldexp, logb.
5385 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5387 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5388 support, by removing commented-out code and briefly listing the
5389 C89 functions excluded. The commented-out stuff was confusing
5390 maintenance, e.g., we thought we needed cbrt but it was commented out.
5391 (logb): Remove decl; no longer needed.
5392 (isfinite): New macro, if not already supplied.
5393 (isnan): Don't replace any existing macro.
5394 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5395 are present on all C89 platforms.
5396 (Ffrexp): Do not special-case zero, as frexp does the right thing
5398 (Flogb): Do not use logb, as it doesn't have the desired meaning
5399 on hosts that use non-base-2 floating point. Instead, stick with
5400 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5401 frexp, to avoid getting an unspecified result.
5403 * xdisp.c (Qinhibit_debug_on_message): Now static.
5405 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5407 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5408 NSBezierPath (Bug#12131).
5410 2012-09-10 Chong Yidong <cyd@gnu.org>
5412 * fns.c (Fdelq, Fdelete): Doc fix.
5414 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5416 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5417 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5419 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5421 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5422 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5425 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5427 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5428 left fringe if the window has a left margin. This avoids leaving
5429 traces of the cursor because its leftmost pixel is not drawn over.
5431 * dispnew.c (update_window_line): When the left margin area of a
5432 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5433 that screen line. (Bug#12277)
5435 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5437 Assume C89 or later for math functions (Bug#12381).
5438 This simplifies the code, and makes it a bit smaller and faster,
5439 and (most important) makes it easier to clean up signal handling
5440 since we can stop worring about floating-point exceptions in
5441 library code. That was a problem before C89, but the problem
5442 went away many years ago on all practical Emacs targets.
5443 * data.c, image.c, lread.c, print.c:
5444 Don't include <math.h>; no longer needed.
5445 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5446 might be autoconfigured, as that never happens.
5448 * doprnt.c (DBL_MAX_10_EXP):
5449 * print.c (DBL_DIG):
5450 Remove. C89 or later always defines these.
5451 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5452 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5453 (arith_error, domain_error, domain_error2):
5454 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5455 no longer needed -- we simply return what C returns. All uses removed.
5456 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5458 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5459 Remove. All uses expanded, as these macros are no longer used
5460 more than once and are now more trouble than they're worth.
5461 (Ftan): Use tan, not sin / cos.
5462 (Flogb): Assume C89 frexp.
5463 (fmod_float): Assume C89 fmod.
5464 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5465 (init_floatfns): Remove. All uses removed.
5467 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5469 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5470 compositeToPoint for OSX < 10.6 (Bug#12390).
5472 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5474 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5475 This produces more-accurate results.
5477 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5479 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5480 changes (Bug#12088).
5482 2012-09-08 Chong Yidong <cyd@gnu.org>
5484 * syntax.c (Fstring_to_syntax): Doc fix.
5486 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5488 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5489 in the internal border.
5490 (x_set_window_size): Remove static variables and their usage.
5491 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5492 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5493 Remove fringe/internal border adjustment (Bug#11052).
5494 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5495 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5496 (ns_fix_rect_ibw): Remove.
5497 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5498 (ns_dumpglyphs_box_or_relief): Ditto.
5499 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5501 (ns_dumpglyphs_image): Ditto.
5502 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5504 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5505 their usage. Add fringe_extended_p and its use as in other terms.
5506 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5507 scroll bar was removed.
5508 (updateFrameSize): New function.
5509 (windowDidResize): Move code to updateFrameSize and call it.
5511 * nsterm.h (EmacsView): Add updateFrameSize.
5513 2012-09-07 Chong Yidong <cyd@gnu.org>
5515 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5517 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5519 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5521 More signal-handler cleanup (Bug#12327).
5522 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5523 Problem introduced when merging patches. Noted by Eli Zaretskii in
5524 <http://bugs.gnu.org/12327#67>.
5525 * floatfns.c: Comment fix.
5526 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5527 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5528 and anyway the declaration is harmless even if SIGDANGER is not defined.
5529 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5530 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5531 source files not surprisingly expected syssignal.h to define, or
5532 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5533 Include <sys/ioctl.h>, for FIONREAD.
5534 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5535 This eliminates a problem whereby other files mysteriously had
5536 to include "syssignal.h" before including "systty.h" if they
5537 wanted to use "#ifdef SIGIO".
5539 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5541 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5543 * w32.c (sigemptyset): Empty the set.
5544 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5546 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5548 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5550 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5551 (mark_object): Likewise for frame objects.
5553 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5555 * syssignal.h (handle_on_main_thread): Always declare,
5556 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5557 This ports to platforms without HAVE_PTHREAD.
5559 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5561 Signal-handler cleanup (Bug#12327).
5562 Emacs's signal handlers were written in the old 4.2BSD style with
5563 sigblock and sigmask and so forth, and this led to some
5564 inefficiencies and confusion. Rewrite these to use
5565 pthread_sigmask etc. without copying signal sets around. Also,
5566 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5567 'signal', and instead use functions that do not attempt to take
5568 over the system name space. This patch causes Emacs's text
5569 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5570 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5571 Do not include <signal.h> or "syssignal.h", as these
5572 modules do not use signals.
5573 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5574 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5575 Do not include <signal.h>, as "syssignal.h" does that for us now.
5576 * atimer.c (sigmask_atimers): New function.
5577 (block_atimers, unblock_atimers): New functions,
5578 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5580 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5581 no longer needed here.
5582 * emacs.c (main): Inspect existing signal handler with sigaction,
5583 so that there's no need to block and unblock SIGHUP.
5584 * sysdep.c (struct save_signal): New member 'action', replacing
5585 old member 'handler'.
5586 (save_signal_handlers, restore_signal_handlers):
5587 Use sigaction instead of 'signal' to save and restore.
5588 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5589 New function. All users of 'signal' modified to use set_sighandler
5590 if they're writeonly, and to use sys_signal if they're read+write.
5591 (emacs_sigaction_init, forwarded_signal): New functions.
5592 (sys_signal): Remove. All uses replaced by calls to sigaction
5593 and emacs_sigaction_init, or by direct calls to 'signal'.
5594 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5595 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5596 all uses replaced by pthread_sigmask etc. calls.
5597 * syssignal.h: Include <signal.h>.
5598 (emacs_sigaction_init, forwarded_signal): New decls.
5599 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5600 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5601 (sigmask, sys_sigmask): Remove; no longer needed.
5602 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5603 (sigblock, sigunblock, sigfree):
5604 (sigsetmask) [!defined sigsetmask]:
5605 Remove. All uses replaced by pthread_sigmask.
5606 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5607 no longer need to be replaced, and its typical old uses
5608 are now done via emacs_sigaction_init and sigaction.
5609 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5610 (sys_sigdel): Remove; unused.
5611 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5613 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5615 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5616 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5618 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5620 Explicitly mark buffer_defaults and buffer_local_symbols.
5621 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5622 mark_local_symbols here.
5623 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5624 since special buffers aren't marked here any more.
5625 (allocate_buffer): Chain new buffer with all_buffers here...
5626 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5628 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5629 (syms_of_buffer): Remove staticpro of the above.
5630 (init_buffer_once): Set names for buffer_defaults and
5631 buffer_local_symbols.
5633 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5635 Use bool for booleans in font-related modules.
5636 * font.c (font_intern_prop, font_style_to_value)
5637 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5638 (generate_otf_features, font_check_otf_features, font_check_otf)
5639 (font_match_p, font_list_entities, font_at):
5640 * fontset.c (fontset_id_valid_p, reorder_font_vector
5641 (fontset_find_font, Fset_fontset_font)
5642 (face_suitable_for_char_p) [0]:
5643 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5644 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5645 (m17n_flt_initialized, ftfont_shape_by_flt):
5646 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5647 * nsfont.m (nsfont_draw):
5648 * w32font.c (w32font_draw):
5649 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5650 Use bool for booleans.
5651 * font.h: Adjust to above API changes.
5652 (struct font, struct font_driver, struct font_driver_list):
5653 Use bool for booleans.
5654 (struct font): Remove useless member encoding_type.
5656 * fontset.c, xftfont.c: Omit unnecessary static decls.
5658 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5660 * alloc.c (mark_object): Revert window marking code
5661 since it's unsafe for the Fset_window_configuration.
5663 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5665 Fix race conditions with signal handlers and errno (Bug#12327).
5666 Be more systematic about preserving errno whenever a signal
5667 handler returns, even if it's not in the main thread. Do this by
5668 renaming signal handlers to distinguish between signal delivery
5669 and signal handling. All uses changed.
5670 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5671 * data.c (deliver_arith_signal): Rename from arith_error.
5672 * dispnew.c (deliver_window_change_signal): Rename from
5673 window_change_signal.
5674 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5675 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5676 * keyboard.c (deliver_input_available_signal): Rename from
5677 input_available_signal.
5678 (deliver_user_signal): Rename from handle_user_signal.
5679 (deliver_interrupt_signal): Rename from interrupt_signal.
5680 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5681 (deliver_child_signal): Rename from sigchld_handler.
5682 * atimer.c (handle_alarm_signal):
5683 * data.c (handle_arith_signal):
5684 * dispnew.c (handle_window_change_signal):
5685 * emacs.c (handle_fatal_signal, handle_danger_signal):
5686 * keyboard.c (handle_input_available_signal):
5687 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5688 * process.c (handle_pipe_signal, handle_child_signal):
5689 New functions, with the actual signal-handling code taken from the
5690 original respective signal handlers, sans the sporadic attempts to
5691 preserve errno, since that's now done by handle_on_main_thread.
5692 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5693 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5694 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5696 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5697 Move initialization of main_thread to sysdep.c's init_signals.
5698 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5699 our usage, and simplifies the mainline code.
5700 (record_child_status_change): New static function, as a helper
5701 for handle_child_signal, and with most of the old child handler's
5703 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5704 (handle_child_signal): Use the above.
5705 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5706 Moved here from emacs.c.
5707 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5708 code moved here from emacs.c's main function.
5709 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5710 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5711 This lets callers save and restore errno properly.
5713 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5715 Remove redundant or unused things here and there.
5716 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5717 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5718 * editfns.c (Fcompare_buffer_substrings): Likewise.
5719 * frame.h (struct terminal, struct font_driver_list):
5720 Remove redundant declarations.
5721 * window.h (Qleft, Qright): Likewise.
5723 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5725 Do not mark objects from deleted buffers, windows and frames.
5726 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5727 (mark_object): Likewise for windows and frames.
5729 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5731 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5732 buffer_defaults and buffer_local_symbols as valid objects.
5733 Return special value to denote them.
5735 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5737 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5738 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5739 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5740 (file_name_absolute_p, Fsubstitute_in_file_name):
5741 (check_executable, check_writable, Ffile_accessible_directory_p)
5742 (Fset_file_selinux_context, Fdefault_file_modes)
5743 (Finsert_file_contents, choose_write_coding_system)
5744 (Fwrite_region, build_annotations, a_write, e_write)
5746 * filelock.c (boot_time_initialized, get_boot_time)
5747 (get_boot_time_1, lock_file_1, within_one_second):
5748 * floatfns.c (in_float):
5749 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5750 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5751 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5752 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5753 * window.c (compare_window_configurations):
5754 Use bool for booleans.
5755 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5756 (Fdefault_file_modes): Now mode_t, not int, for modes.
5757 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5758 (internal_delete_file): Now returns void, not a (boolean) int,
5759 since nobody was looking at the return value.
5760 * lisp.h, window.h: Adjust to above API changes.
5762 * xdisp.c (set_message): Simplify and reindent last change.
5764 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5766 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5768 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5770 * eval.c (call_debugger): Make the function non-static so that we
5771 can call it from set_message.
5773 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5774 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5776 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5778 Give more-useful info on a fatal error (Bug#12328).
5779 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5780 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5781 of doing the work ourselves.
5782 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5783 do most of the work.
5784 (fatal_error_backtrace): New function, taken from the guts
5785 of the old fatal_error_signal, but with a new option to output
5787 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5788 info about the signal than just its number.
5789 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5790 * sysdep.c: Include <execinfo.h>
5791 (emacs_backtrace): New function, taken partly from the previous
5792 code of the 'die' function.
5793 (emacs_abort): Call fatal_error_backtrace rather than abort.
5795 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5797 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5798 eager (load-time) macro-expansion.
5799 * lisp.mk (lisp): Add macroexp.
5801 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5803 Simplify redefinition of 'abort' (Bug#12316).
5804 Do not try to redefine the 'abort' function. Instead, redo
5805 the code so that it calls 'emacs_abort' rather than 'abort'.
5806 This removes the need for the NO_ABORT configure-time macro
5807 and makes it easier to change the abort code to do a backtrace.
5808 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5809 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5810 Remove; sysdep.c's emacs_abort now takes its place.
5811 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5812 'abort' changed to use 'emacs_abort'.
5813 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5814 (abort) [!defined abort]: Rename to ...
5815 (emacs_abort): ... new name.
5816 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5817 the place of the old 'abort' in emacs.c.
5818 * w32.c, w32fns.c (abort): Do not #undef.
5819 * w32.c (emacs_abort): Rename from w32_abort.
5821 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5823 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5824 offsets[j].dv, since the y axis of the screen coordinates points
5825 down, while the y axis of the font definition coordinates points
5826 up. This fixes display of Arabic diacritics such as KASRA and
5827 KASRATAN. (Bug#11860)
5829 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5831 Be more systematic about _setjmp vs setjmp.
5832 * alloc.c (test_setjmp, mark_stack):
5833 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5834 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5835 (png_load, my_error_exit, jpeg_load):
5836 * process.c (send_process_trap, send_process):
5837 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5838 The underscored versions are up to 30x faster on some hosts.
5839 Formerly, the code used setjmp+longjmp sometimes and
5840 _setjmp+_longjmp at other times, with no particular reason to
5841 prefer setjmp+longjmp.
5843 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5845 Fix minor problem found by static checking.
5846 * buffer.c (Fdelete_all_overlays): Return nil.
5848 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5850 * buffer.c (Fdelete_all_overlays): New function.
5852 2012-09-03 Chong Yidong <cyd@gnu.org>
5854 * gtkutil.c: Add extern decl for Qxft.
5856 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5858 * emacs.c, eval.c: Use bool for boolean.
5859 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5860 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5861 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5862 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5863 (main, decode_env_path, Fdaemon_initialized):
5864 * eval.c (call_debugger, Finteractive_p, interactive_p):
5865 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5866 (maybe_call_debugger, Fbacktrace):
5867 * process.c (read_process_output, exec_sentinel):
5868 Use bool for booleans.
5869 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5870 All callers changed.
5871 * eval.c (interactive_p): Omit always-true boolean argument
5872 EXCLUDE_SUBRS_P. All callers changed.
5873 * dispextern.h, lisp.h: Reflect above API changes.
5874 * firstfile.c (dummy): Use the address of 'main', whose signature
5875 won't change, instead of the address of 'initialize', whose
5876 signature just changed from int to bool.
5877 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5878 * msdos.c (fatal_error_in_progress): ... from here.
5879 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5881 (redisplay_internal, unwind_redisplay): Simply clear
5882 REDISPLAYING_P when unwinding, instead of saving its previous,
5883 always-false value and then restoring it.
5885 Clean up some extern decls.
5886 Mostly, this hoists extern decls out of .c files and into .h files.
5887 That way, we're more likely to catch errors if the interfaces change.
5888 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5889 declare xg_mark_data.
5890 * dispextern.h (x_frame_parm_handlers):
5892 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5893 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5894 (Qultra_bold, Qoblique, Qitalic):
5895 Move extern decl here from .c file.
5896 * alloc.c (xg_mark_data) [USE_GTK]:
5898 * eval.c (Qlexical_binding):
5899 * fns.c (time) [!HAVE_UNISTD_H]:
5900 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
5901 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
5902 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
5903 * lread.c (Qinternal_interpreter_environment):
5904 * minibuf.c (Qbuffer):
5905 * process.c (QCfamily, QCfilter):
5906 * widget.c (free_frame_faces):
5907 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5908 * xfont.c (x_clear_errors):
5909 * xterm.c (x_frame_parm_handlers):
5910 Remove now-redundant extern decls.
5911 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5912 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5914 * xfaces.c: Remove unnecessary static decls.
5915 * xterm.c (updating_frame): Remove decl of nonexistent object.
5917 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5918 when building globals.h, as the objects that are not built on
5919 this host are not needed to compile C files on this host.
5921 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5923 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5925 * frame.h: Add missing prototype for x_wm_set_size_hint.
5927 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5975 offset adjustment values separately for each cluster. (Bug#11860)
5977 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5978 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5979 about implicit conversions from integer to pointer.

6037 window system declarations.
6039 * frame.h: Move common functions here: set_frame_menubar,
6040 x_set_window_size, x_sync, x_get_focus_frame,
6041 x_set_mouse_position, x_set_mouse_pixel_position,
6042 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6099 for GCC 4.7.1 x86-64.
6101 2012-08-30 Glenn Morris <rgm@gnu.org>
6103 * lread.c (init_lread): For out-of-tree builds, only add the
6104 source directory's site-lisp dir to the load-path if it exists,
6105 consistent with in-tree builds. (Bug#12302)
6107 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6337 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6338 are all boolean, so make them single-bit bitfields.
6340 * lisp.h (ASET): Remove attempt to detect side effects.
6341 It was meant to be temporary and it often doesn't work,
6342 because when IDX has side effects the behavior of IDX==IDX
6343 is undefined. See Stefan Monnier in
6344 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6346 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6354 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6355 as that's faster and simpler than static storage. Don't bother
6356 with the g_main_context_query overhead if g_main_context_pending
6357 says no events are pending.
6358 (gfds, gfds_size): Remove these static vars.
6359 (xgselect_initialize): Remove; no longer needed.
6360 All uses and decls removed.

6379 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6380 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6381 * Makefile.in (LIB_EXECINFO): New macro.
6384 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6385 * bytecode.c (exec_byte_code):
6386 * callint.c (check_mark, Fcall_interactively):
6387 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6388 (getenv_internal, sync_process_alive, call_process_exited):
6389 * lisp.h (USE_SAFE_ALLOCA):
6390 Use bool for booleans, instead of int.
6391 * lisp.h, process.h: Adjust prototypes to match above changes.
6392 * callint.c (Fcall_interactively): Don't assume the mark's
6393 offset fits in 'int'.
6395 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6397 * buffer.c, buffer.h: Use bool for boolean.
6398 * buffer.c (reset_buffer_local_variables)
6399 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6400 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6401 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6402 (overlay_touches_p, overlay_strings, Foverlay_put)
6403 (report_overlay_modification, call_overlay_mod_hooks):
6404 (mmap_enlarge, mmap_set_vars):
6405 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6406 Use bool for booleans, instead of int.
6407 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6408 since the 1-or-0 return value is always ignored anyway.
6409 (mmap_initialized_p):
6410 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6411 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6413 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6415 * bidi.c: Use bool for boolean.
6416 This is a bit more readable, and makes the text segment of bidi.o
6417 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6418 Presumably it's faster too.
6419 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6421 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6422 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6423 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6424 (bidi_explicit_dir_char, bidi_level_of_next_char)
6425 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6426 Use bool for booleans, instead of int.
6427 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6428 (bidi_unshelve_cache): Adjust decls to match code.
6430 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6432 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6435 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6437 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6438 * atimer.h: Include <stdbool.h>.
6440 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6442 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6443 compile time tests instead of run time tests on systems that do
6445 (FRAME_MAC_P): Remove leftover from deleted code.
6446 * frame.c (syms_of_frame): Remove leftover from deleted code.
6448 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6452 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6454 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6455 Otherwise, the compiler complains about (A?B:C) where B is void
6456 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6457 (fontset_add): Return void, for FONTSET_ADD.
6459 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6461 * alloc.c: Use bool for booleans.
6462 (gc_in_progress, abort_on_gc)
6463 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6464 (dont_register_blocks) [GC_MALLOC_CHECK]:
6465 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6466 (check_string_bytes, make_specified_string, memory_full)
6467 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6468 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6469 (mark_stack, valid_pointer_p, make_pure_string)
6470 (Fgarbage_collect, survives_gc_p, gc_sweep):
6471 Use bool for booleans, instead of int.
6472 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6473 Remove unused local.
6474 * alloc.c (PURE_POINTER_P):
6475 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6476 * editfns.c (Fformat):
6477 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6479 * fns.c (sweep_weak_table):
6480 * lisp.h (suppress_checking, push_message, survives_gc_p)
6481 (make_pure_string, gc_in_progress, abort_on_gc):
6482 * lread.c (readchar, read1):
6483 * print.c (Fprin1_to_string):
6484 * xdisp.c (push_message):
6485 Use bool for booleans affected directly or indirectly by
6488 Make recently-introduced setters macros.
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): Rename from their
6492 upper-case counterparts, and make them functions rather than macros.
6493 This is more consistent with the other recently-introduced setters.
6494 These don't need to be inline, since they're local.
6496 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6498 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6499 the loop (Bug#12247).
6501 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6503 * lisp.h (vcopy): Use memcpy rather than our own loop.
6504 This fixes a performance regression introduced by the recent
6505 addition of vcopy. This means 'vcopy' will need to be modified
6506 for a copying collector, but that's OK. Also, tighten the
6507 checking in the assertion.
6509 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6511 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6512 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6513 non-base glyph for the width of the base character, according to
6514 what x_draw_composite_glyph_string_foreground expects.
6515 Generate WADJUST value according to composition_gstring_width's
6516 expectations, to produce correct width of the composed character.
6517 Reverse the sign of the DU offset produced by ScriptPlace.
6519 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6521 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6523 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6525 Avoid direct writes to contents member of struct Lisp_Vector.
6526 * lisp.h (vcopy): New function to copy data into vector.
6527 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6528 * fns.c (Ffillarray): Use ASET.
6529 * keyboard.c (timer_check_2): Use AREF and ASET.
6530 (append_tool_bar_item, Frecent_keys): Use vcopy.
6531 * lread.c (read_vector): Use ASET.
6532 * msdos.c (Frecent_doskeys): Use vcopy.

6540 the position of its buffer's point.
6541 (Fset_window_point): For the selected window always go in its
6542 buffer to the specified position.
6544 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6546 Setter macros for fontsets.
6547 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6548 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6549 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6552 2012-08-20 Glenn Morris <rgm@gnu.org>
6554 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6555 Don't assume that `ln -f' works.
6557 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6559 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6560 and later about non-assignments with no effect. See discussion at
6561 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6564 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6566 Inline setter functions for Lisp_Objects slots of struct specbinding.
6567 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6570 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6572 * window.c (select_window): Always make selected window's buffer
6575 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6577 Use AREF and ASET for docstrings of category tables.
6578 * category.h (CATEGORY_DOCSTRING): Use AREF.
6579 (SET_CATEGORY_DOCSTRING): Use ASET.
6580 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6582 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6584 Inline setter functions for hash table members.
6585 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6586 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6587 (set_hash_key_and_value, set_hash_index, set_hash_next)
6588 (set_hash_hash): New functions.
6589 * charset.c, fns.c: Adjust users.
6591 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6593 Inline getter and setter functions for per-buffer values.

6597 * buffer.c, data.c: Adjust users.
6599 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6601 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6603 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6605 Rely on <config.h> + <unistd.h> to declare 'environ',
6606 as gnulib does this if the system doesn't.
6607 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6608 Remove declaration. MS-Windows declares it on stdlib.h which is
6609 included by conf_post.h.
6610 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6611 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6612 * vm-limit.c: Include <unistd.h>, for 'environ'.
6614 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6615 (start_of_data): Remove decl; mem-limits.h provides it.
6617 * xdisp.c (handle_invisible_prop): Make it a bit faster
6618 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6620 2012-08-19 Chong Yidong <cyd@gnu.org>
6622 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6625 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6627 * .gdbinit: Use call instead of set when calling a function in the
6630 * data.c (set_internal): Don't use set_blv_found.
6631 (Fkill_local_variable): Likewise.
6633 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6635 * nsfont.m (ns_ascii_average_width): Ensure the string
6636 ascii_printable is initialized with a null-terminated character
6637 array. Otherwise, it can contain undesired extra characters.
6639 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>

6642 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6643 Return void, not Lisp_Object. Otherwise, the compiler
6644 complains about (A?B:C) where B is void and C is Lisp_Object
6645 when compiling CHAR_TABLE_SET, due to the recent change to
6646 the API of sub_char_table_set_contents.
6648 2012-08-18 Chong Yidong <cyd@gnu.org>
6650 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6651 for the string case (Bug#3874).

7479 * w32.c (init_environment): Change the default values of many
7480 environment variables in dflt_envvars[] to NULL, to avoid pushing
7481 them into environment when they were not already defined.
7482 Remove the code that deletes site-lisp subdirectories from the default
7483 value of EMACSLOADPATH, as it is no longer needed.
7484 (check_windows_init_file): Now external, not static.
7485 Use Vload_path as is, without adding anything, as this function is now
7486 called when Vload_path is already set up.
7488 * w32.h (check_windows_init_file): Add prototype.
7490 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7533 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7534 Remove unnecessary pointer casts.
7535 * alloc.c (record_xmalloc): New function.
7536 * lisp.h (record_xmalloc): New decl.
7537 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7538 more like a function. This is because the pointer cast is not
7539 needed. All uses changed.
7540 * print.c (print_string, print_error_message): Avoid length recalc.
7542 Improve fix for macroexp crash with debugging (Bug#12118).
7543 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7544 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7545 not supposed to be invoked from the garbage collector.

7547 (gc_aset): New function, which is like ASET but can be
7548 used in the garbage collector.

7572 (sys_rename): Diagnose renaming of a symlink when the user doesn't
7573 have the required privileges.
7574 (get_file_security_desc_by_name): Rename from

7577 with addition of handling of symlinks and support for 'lstat'.
7578 If possible, get file's attributes and security information by
7579 handle, not by name. Produce S_IFLNK bit for symlinks, when
7580 called from 'lstat'.
7581 (stat, lstat): New functions, call 'stat_worker'.
7582 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7583 symlinks when the underlying filesystem supports them.
7585 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7587 Fix macroexp crash on Windows with debugging (Bug#12118).
7588 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7589 checking subscripts; problem introduced with the recent
7590 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7591 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7592 since it's used in non-static inline functions now.
7594 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7595 Don't assume buffer size fits in 'int'. Remove unused local.

7615 * composite.c (COMPOSITE_INLINE):
7616 * dispnew.c (DISPEXTERN_INLINE):
7617 * sysdep.c (SYSTIME_INLINE):
7618 Define to EXTERN_INLINE, so that the corresponding functions
7619 are compiled into code.
7620 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7621 (INLINE_HEADER_END): New macros.
7622 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7642 hard-coding the path separator.
7644 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7646 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7647 This how ASET and AREF are supposed to work, and makes
7648 it easier to think about future improvements. See
7649 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7650 * charset.h (set_charset_attr): New function.

8139 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8140 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8141 emacs.c, as this is a more-suitable home. Had this been done earlier
8142 the fix for 12036 would have avoided some of the problems noted in
8143 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8144 would have been more obvious.
8145 * emacs.c: Do not include <verify.h>; no longer needed.
8146 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8147 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8148 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8149 Remove; now done in lisp.h.
8150 * lisp.h (PUBLISH_TO_GDB): New macro.
8151 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8152 (DATA_SEG_BITS): Use it.
8153 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8154 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8155 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8156 not be usable in #if. This simplifies things.
8158 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8160 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8162 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8164 Simplify export of symbols to GDB (Bug#12036).
8165 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8166 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8167 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8168 Adjust to changes in lisp.h and emacs.c, by using
8169 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8170 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8171 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8172 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8173 instead of gdb_valbits.
8174 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8175 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8176 instead of gdb_array_mark_flag.
8177 (xboolvector): Get size from $->size, not $->header.size.
8178 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8179 (xreload, hook-run, hookpost-run): Remove.
8180 * emacs.c: Include <verify.h>.
8181 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8182 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8184 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8185 (gdb_USE_LSB_TAG): New enum constants.
8186 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8187 Also define these as enum constants, so they're visible to GDB.
8188 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8189 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8190 as constants, so they're visible to GDB.
8191 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8192 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8193 Now enum constants, not macros, so they're visible to GDB.
8194 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8195 more convenient now. All uses changed.
8196 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8197 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8199 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
8201 Explicitly free restriction data that are not needed anymore.
8202 * editfns.c (save_restriction_restore): Free restriction data.
8204 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8206 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8207 add argument, tune behavior, and adjust all callers.
8209 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8211 Use typedef for EMACS_INT, EMACS_UINT.
8212 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8213 than macros. This simplifies debugging in the usual case, since
8214 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8215 and it allows expressions involving EMACS_INT casts.
8216 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8218 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8220 * nsterm.m (ns_read_socket): Return early if there is a modal

8226 that FOCUS-FRAME can be omitted.
8228 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8230 Adjust buffer text indirection counters at the end of Fkill_buffer.
8231 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8232 buffer is definitely dead. This should really fix an issue reported
8233 by Christoph Scholtes again. (Bug#12007).
8234 (init_buffer_once): Initialize indirection counters of
8235 buffer_defaults and buffer_local_symbols (for sanity and safety).
8237 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8239 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8240 and continuation glyphs on tooltip frames, leave them at zero.
8241 Avoids continued lines in tooltips. (Bug#11832)
8243 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8245 Simplify copy_overlay.
8246 * buffer.c (copy_overlay): Simplify. Use build_marker.

8252 or invalid. (Bug#12025)
8254 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
8255 it signals an error when a tooltip frame is being created.
8257 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8259 Cleanup miscellaneous objects allocation and initialization.

8266 (build_overlay): Add prototype.
8268 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8270 Swap buffer text indirection counters in Fbuffer_swap_text.
8271 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8272 This avoids crash reported by Christoph Scholtes at
8273 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8275 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8277 * nsmenu.m (Popdown_data): New struct.
8278 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8280 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

8282 and autorelease them. Also autorelease img and matrix (Bug#12005).
8283 (dealloc): Remove (Bug#12005).

8300 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8302 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8303 as it's limited by the amount of memory, not by INT_MAX.
8305 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8307 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8308 in special-event-map. See the discussion at

8389 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8390 'for_each_per_buffer_object_at'.
8391 All uses changed. It's better to use upper-case for macros that

8443 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8445 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

8458 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8460 * eval.c (Fdefvar): Don't check constants since we only set the var if
8461 it's not yet defined anyway (bug#11904).
8463 * lisp.h (last_undo_boundary): Declare new var.
8464 * keyboard.c (command_loop_1): Set it.
8465 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8466 were auto-added by the command loop (bug#11774).
8468 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

9037 * systime.h: Include <sys/time.h> on all hosts, not just if
9038 WINDOWSNT, since 'struct timeval' is needed in general.
9039 (EMACS_TIME): Now a typedef, not a macro.
9040 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9042 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9045 (EMACS_TIME_LE): Now functions, not macros.
9046 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9047 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9048 which are not functions. All uses rewritten to use:
9049 (make_emacs_time): New function.
9050 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9051 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9052 not functions. All uses rewritten to use the following, respectively:
9053 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9054 (add_emacs_time, sub_emacs_time): New functions.
9055 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9056 * fileio.c (Fcopy_file):
9057 * xterm.c (XTflash): Get the current time closer to when it's used.
9058 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9075 Prefer memcmp to strncmp when either will do.
9076 * nsterm.m: Include <ftoastr.h>.
9078 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9079 Prefer snprintf to strncpy.
9080 * nsterm.m (ns_term_init):
9081 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9082 * nsterm.m (ns_term_init):
9083 Avoid the need for strncpy, by using build_string or
9084 make_unibyte_string directly. Use dtoastr, not snprintf.
9085 * process.c (Fmake_network_process): Diagnose service names that
9086 are too long, rather than silently truncating them or creating
9087 non-null-terminated names.
9088 (Fnetwork_interface_info): Likewise, for interface names.
9089 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9090 Prefer sprintf to strncat.
9091 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9092 Prefer vsnprintf to vsprintf + strncpy.
9094 2012-07-10 Glenn Morris <rgm@gnu.org>
9096 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9097 Clarify fallback case.
9099 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9101 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9102 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9103 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9104 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9105 where argument type is known to be a Lisp_Cons.

9117 Optimize pure C strings initialization.
9118 * lisp.h (make_pure_string): Fix prototype.
9119 (build_pure_c_string): New function, defined as static inline. This
9120 provides a better opportunity to optimize away calls to strlen when
9121 the function is called with compile-time constant argument.
9122 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9123 argument, adjust users accordingly. Use build_pure_c_string where
9125 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9126 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9127 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9129 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9131 Avoid calls to strlen in miscellaneous functions.
9132 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9133 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9134 * lread.c (openp): Likewise.
9136 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9138 Avoid calls to strlen in path processing functions.
9139 * fileio.c (file_name_as_directory): Add comment. Change to add
9140 srclen argument and return the length of result. Adjust users
9142 (directory_file_name): Fix comment. Change to add srclen argument,
9143 swap 1st and 2nd arguments to obey the common convention.
9144 Adjust users accordingly.
9145 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9147 2012-07-10 Glenn Morris <rgm@gnu.org>
9149 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9150 Move PENDING_OUTPUT_COUNT definition to configure.
9152 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9153 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9154 * s/gnu.h (DATA_START): Move definitions to configure.
9156 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9157 We include usg5-4-common.h, which defines them both.
9159 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9160 O_RDONLY already includes it).
9162 Stop ns builds setting the EMACSLOADPATH environment variable.
9163 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9164 Now it does not set EMACSLOADPATH, just returns the load-path string.
9165 * nsterm.h: Update accordingly.
9166 * lread.c [HAVE_NS]: Include nsterm.h.
9167 (init_lread) [HAVE_NS]: Use ns_load_path.
9168 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9170 2012-07-09 Glenn Morris <rgm@gnu.org>
9172 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9173 since the included bsd-common.h does so.
9175 Stop ns builds setting the EMACSPATH environment variable.
9176 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9177 (ns_init_paths): Do not set EMACSPATH.
9178 * nsterm.h (ns_exec_path): Add it.
9179 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9182 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9184 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9186 * process.c (wait_reading_process_output): 'waitchannels' was unset
9187 when read_kbd || !NILP (wait_for_cell); fix this.
9189 Add GCC-style 'const' attribute to functions that can use it.
9190 * character.h (char_resolve_modifier_mask):
9191 * keyboard.h (make_ctrl_char):
9192 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9193 (init_character_once, next_almost_prime, init_fns, init_image)
9194 (flush_pending_output, init_sound):
9195 * mem-limits.h (start_of_data):

9199 Declare the dummy function with ATTRIBUTE_CONST.
9200 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9201 Add decls with ATTRIBUTE_CONST.
9203 Minor improvements to make_formatted_string.
9204 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9205 where int is good enough, as vsprintf returns an int.
9206 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9208 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9210 Use make_formatted_string to avoid double length calculation.
9211 * lisp.h (make_formatted_string): New prototype.
9212 * alloc.c (make_formatted_string): New function.
9213 * buffer.c (Fgenerate_new_buffer_name): Use it.
9214 * dbusbind.c (syms_of_dbusbind): Likewise.

9216 * filelock.c (get_boot_time): Likewise.
9217 * frame.c (make_terminal_frame, set_term_frame_name)
9218 (x_report_frame_params): Likewise.
9219 * image.c (gs_load): Likewise.
9220 * minibuf.c (get_minibuffer): Likewise.

9233 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
9235 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9237 Move marker debugging code under MARKER_DEBUG.
9238 * marker.c (MARKER_DEBUG): Move marker debugging code under
9239 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9240 for bootstrap with --enable-checking (~3x slowdown reported
9241 by Juanma Barranquero <lekktu@gmail.com>).
9242 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9244 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9246 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9247 See <http://bugs.gnu.org/11825#29>.
9249 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9251 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9252 has no font, use the frame's font. (Bug#11813)
9253 (display_line): Add commentary about displaying truncation glyphs
9255 (produce_special_glyphs): Move here from term.c.
9257 * term.c (produce_special_glyphs): Move to xdisp.c.
9259 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9262 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9264 * xdisp.c (display_line): Avoid warning about implicit declaration
9267 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9269 * lisp.h: Remove empty conditional.
9271 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9273 * lread.c (load_path_check): Now static.
9275 Fix some minor --with-ns problems found by static checking.
9276 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9277 (x_set_font) [!HAVE_X_WINDOWS]:
9278 * image.c (xpm_load_image) [HAVE_NS]:
9279 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9280 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9281 Remove unused local.
9282 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9283 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9284 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9285 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9286 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9287 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9288 Fix pointer signedness problem.
9289 * xfaces.c (FRAME_X_FONT_TABLE):
9290 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9292 2012-07-07 Glenn Morris <rgm@gnu.org>
9294 * lread.c (load_path_check): New function, split from init_lread.
9295 (init_lread): Reorganize. Motivation:
9296 If EMACSLOADPATH is set, check/warn about that rather than the
9297 defaults, which we are not going to use. Hence we can remove
9298 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9299 Don't warn if site-lisp directories are missing.
9300 If not installed, start from a blank load-path, since
9301 PATH_LOADSEARCH refers to the eventual installation directories.
9303 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9305 Support truncation and continuation glyphs on GUI frames, when
9306 fringes are disabled. (Bug#11832)
9307 * xdisp.c (init_iterator): Get dimensions of truncation and
9308 continuation glyphs even if on GUI frames.
9309 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9310 or both, are absent.
9311 (start_display, move_it_in_display_line_to): Handle the case of a
9312 GUI frame without a fringe to display continuation or truncation
9314 (insert_left_trunc_glyphs): Support GUI frames: make sure
9315 truncation glyphs overwrite enough glyphs from the current line to
9316 have sufficient space in pixels.
9317 (display_line): Support truncation and continuation glyphs on GUI
9318 frames. If some spare pixels are left on the line after inserting
9319 the truncation glyphs, fill that space with a stretch glyph of a
9320 suitably computed width.
9322 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9323 produce_glyphs, to support GUI sessions.
9325 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9327 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9329 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9331 Do not require float-time's arg to fit in time_t (Bug#11825).
9332 This works better on hosts where time_t is unsigned, and where
9333 float-time is applied to the (negative) difference between two times.
9334 * editfns.c (decode_time_components): Last arg is now double *,
9335 not int *, and means to store all the result as a double, without
9336 worrying about whether the seconds part fits in time_t.
9337 All callers changed.
9338 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9339 All callers changed.
9340 (Ffloat_time): Do not fail merely because the specified time falls
9341 outside of time_t range.
9343 2012-07-07 Glenn Morris <rgm@gnu.org>
9345 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9346 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9347 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9349 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9351 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9352 Update dependencies.
9354 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9356 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9358 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9359 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9360 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9361 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9362 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9363 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9365 * xfont.c (compare_font_names): Redo to omit the need for casts.
9367 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9369 * xfns.c (Fx_change_window_property): Doc fix.
9370 * w32fns.c (Fx_change_window_property): Doc fix.
9372 * w32fns.c (Fx_window_property): Accept the same arguments as the
9373 X Windows version. Doc fix.
9374 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9376 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9377 Eli Zaretskii <eliz@gnu.org>
9379 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9380 Windows-specific code from nt/config.nt moved here.
9381 Obsolete settings removed.
9383 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9385 * process.c: Avoid unnecessary calls to gettime.
9386 (wait_reading_process_output): Don't get the time of day
9387 when gobbling data immediately and not waiting, as there's no need
9388 for it in that case. This removes a FIXME.
9390 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9392 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9393 is defined (Bug#11768).
9395 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9397 Fix marker debugging code.
9398 * marker.c (byte_char_debug_check): Do not perform the check
9399 if buffer is not multibyte.
9400 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9401 Call byte_char_debug_check with correct arguments.
9403 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9405 Compile marker debugging code only if ENABLE_CHECKING is defined.
9406 * marker.c (byte_char_debug_check, count_markers):
9407 Use only if ENABLE_CHECKING is defined.
9408 (byte_debug_flag): Remove.
9409 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9410 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9412 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9414 Avoid code repetition in marker-related functions.
9415 * marker.c (attach_marker): New function.
9416 (Fset_marker, set_marker_restricted, set_marker_both)
9417 (set_marker_restricted_both): Use it.
9418 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9419 Consistently rename charno to charpos.
9420 (marker_position): Add eassert.
9421 (marker_byte_position): Convert to eassert.
9423 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9425 Simplify list operations in unchain_overlay and unchain_marker.

9440 * window.c (save_window_save): Likewise.
9442 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9444 Do not use Fdelete_overlay in delete_all_overlays
9445 to avoid redundant calls to unchain_overlay.
9446 * buffer.c (drop_overlay): New function.
9447 (delete_all_overlays, Fdelete_overlay): Use it.
9448 * minibuf.c (get_minibuffer): Fix comment.
9450 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9452 Port to OpenBSD 5.1 amd64.
9453 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9454 This is needed for OpenBSD, and should be harmless on all BSD systems.
9455 Also, include <sys/sysctl.h>, as it should be available on all
9456 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9457 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9458 use p_pid member, not kp_proc.pid.
9460 2012-07-06 Glenn Morris <rgm@gnu.org>
9462 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9464 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9466 More xmalloc and related cleanup.

9474 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9475 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9477 Omit needless casts involving void * pointers and allocation.
9478 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9479 as the former is more robust if P's type is changed.
9480 Prefer xzalloc to xmalloc + memset 0.
9481 Simplify malloc-or-realloc to realloc.
9482 Don't worry about xmalloc returning a null pointer.
9483 Prefer xstrdup to xmalloc + strcpy.
9484 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9486 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9487 alloca of a constant.
9489 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9491 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9492 hscroll is larger than the line width. Fixes long and futile
9493 looping inside extend_face_to_end_of_line (on a TTY) producing
9494 glyphs that are not needed and thrown away.
9496 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9498 * marker.c (set_marker_restricted_both): Simplify by using

9508 not defined (Bug#11768).
9509 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9510 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9511 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9512 followed by gtk_box_set_homogeneous (Bug#11768).
9513 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9514 (update_theme_scrollbar_width, xg_create_scroll_bar):
9515 Use gtk_scrollbar_new (Bug#11768).
9516 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

9524 * xdisp.c (window_hscroll_limited): New function.
9525 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9526 coordinates when window's hscroll is set to insanely large
9529 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9531 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9592 * fileio.c (time_error_value): Check the right error number.
9593 Problem reported by Troels Nielsen in
9594 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9596 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9598 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9599 This should be fixed in a better way; see Eli Zaretskii in
9600 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9601 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9603 * fileio.c (time_error_value): Rename from special_mtime.
9604 The old name's problems were noted by Eli Zaretskii in
9605 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9607 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9608 This variable's comment says Emacs needs at least one GDB-visible
9609 symbol of type enum pvec_type, to work around GDB problems.
9610 The symbol's value doesn't matter.
9612 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9613 that causes compilation to fail on pre-C99 compilers.
9615 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9617 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9622 * buffer.c (init_buffer_once): Fix initialization of
9623 headers for buffer_defaults and buffer_local_symbols.
9624 Reported by Juanma Barranquero <lekktu@gmail.com>.
9626 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9628 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9629 * lisp.h (enum pvec_type): Use fewer bits.
9630 (PSEUDOVECTOR_SIZE_BITS): New constant.
9631 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9632 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9633 change in pvec_type.
9634 (PSEUDOVECTOR_TYPEP): New macro.
9635 (TYPED_PSEUDOVECTORP): Use it.
9636 * fns.c (internal_equal): Adapt code to extract pvectype.

9640 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9641 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9642 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9643 abusing vector->header.next.nbytes.
9644 (live_vector_p): Use PVEC_TYPE.
9645 (mark_object): Adapt code to extract pvectype. Use switch.
9647 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9649 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9650 Tighten new eassert a bit.
9652 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9654 Fix compilation with --enable-gcc-warnings and -O1
9656 * doprnt.c (doprnt): Change type of tem to int, initialize
9657 to avoid compiler warning. Add eassert.
9658 * search.c (simple_search): Initialize match_byte to avoid
9659 compiler warning. Add eassert.
9661 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9663 Avoid weird behavior with large horizontal scrolls.
9664 Without this change, for example, large hscroll values would
9665 mess up Emacs's display on Fedora 15 x86, presumably due to
9666 overflows in int calculations in the display code.
9667 Also, if buffers had long lines, Emacs would freeze.
9668 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9669 (set_window_hscroll): New function, containing the old guts of
9670 Fset_window_hscroll. Return the clipped value.
9671 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9672 This avoids the need to check against PTRDIFF_MAX.
9674 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9676 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9678 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9680 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9682 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9683 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9684 since GCC 4.4.6 issues a bogus warning for them.
9686 Fix bugs in file timestamp newness comparisons.
9687 * fileio.c (Ffile_newer_than_file_p):
9688 * lread.c (Fload): Use full timestamp resolution of files,
9689 not just the 1-second resolution, so that files that are only
9690 slightly newer still count as newer.
9691 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9692 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9694 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9696 * fileio.c: Improve handling of file time marker. (Bug#11852)
9697 (special_mtime): New function.
9698 (Finsert_file_contents, Fverify_visited_file_modtime):
9699 Use it to set special mtime values consistently.
9701 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9703 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9704 marker for non-existing file. (Bug#11852)
9706 2012-07-03 Glenn Morris <rgm@gnu.org>
9708 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9709 and did not make it into globals.h).
9711 2012-07-03 Tom Tromey <tromey@redhat.com>
9713 * window.c (Fset_window_margins, Fset_window_fringes)
9714 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9715 * textprop.c (Fprevious_property_change): No longer static.

9744 * w32term.h: Remove EXFUNs.
9745 * window.h: Remove EXFUNs.

9747 * xterm.h: Remove EXFUN.
9749 2012-07-03 Glenn Morris <rgm@gnu.org>
9751 * lisp.h (Frandom): Make it visible to C.
9752 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9753 buffer for invisible buffers. (Bug#1229)
9755 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9757 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9758 values which aren't power of 2.
9759 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9760 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9763 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9765 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9767 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9769 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9771 * alloc.c (allocate_vector_block): Remove redundant
9772 calls to mallopt if DOUG_LEA_MALLOC is defined.
9773 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9774 avoid calls to mallopt if zero_vector is returned.
9776 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9778 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9779 is enabled, avoid dereferencing NULL current_sblock if
9782 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9784 Cleanup basic buffer management.
9785 * buffer.h (struct buffer): Change layout to use generic vector
9786 marking code. Fix some comments. Change type of 'clip_changed'
9787 to bitfield. Remove unused #ifndef old.
9788 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9789 (GET_OVERLAYS_AT): Fix indentation.
9790 (for_each_per_buffer_object_at): New macro.

9793 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9794 * alloc.c (allocate_buffer): Adjust to match new layout of
9795 struct buffer. Fix comment.
9796 (mark_overlay): New function.

9798 Lisp area of struct buffer.
9799 (mark_object): Use it. Adjust marking of misc objects
9800 and related comments.
9802 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9804 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9805 wrapper that is not needed because the wrapped code is a no-op (zero
9806 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9807 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9809 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9811 * alloc.c (mark_buffer): Simplify. Remove prototype.
9812 (mark_object): Add comment. Reorganize marking of vector-like
9813 objects. Use CHECK_LIVE for all vector-like objects except buffers
9814 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9815 Avoid redundant calls to mark_vectorlike for bool vectors.
9817 2012-06-30 Glenn Morris <rgm@gnu.org>
9819 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9821 * epaths.in (PATH_SITELOADSEARCH): New.
9822 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9823 This is rather than relying on --enable-locallisppath elements
9824 having "site-lisp" in their names. (Bug#10208#25, 11658)
9826 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9828 * w32proc.c (sys_select): Accept and ignore one more argument.
9830 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9832 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9833 (pselect) [!MS_DOS]: Redirect to sys_select.
9835 * sysdep.c: Don't include dos.h and dosfns.h.
9837 * process.c (sys_select):
9838 * msdos.c (sys_select): Accept one more argument and ignore it.
9840 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9841 adapt data types and code to that.
9844 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9845 which clashes with the gnulib function of the same name.
9847 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9849 * font.c (font_style_to_value, font_style_symbolic)
9850 (font_prop_validate_style): Add type checks for values in
9853 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9855 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9858 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9860 * xdisp.c (try_window_id): Undo last change.
9862 * w32.c (getwd): Adjust commentary about startup_dir.
9863 (init_environment): Always call sys_access, even in non-MSVC
9864 builds. Don't chdir to the directory of the Emacs executable.
9865 This undoes code from 1997 which was justified by the need to
9866 "avoid conflicts when removing and renaming directories". But its
9867 downside was that every relative file name was being interpreted
9868 relative to the directory of the Emacs executable, which can never
9869 be TRT. In particular, it broke sys_access when called with
9870 relative file names.
9871 (sys_access): Map GetLastError to errno.
9873 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9875 * window.h (struct window): Change type of 'fringes_outside_margins'

9879 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9882 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9884 * gnutls.c (emacs_gnutls_handshake):
9885 Add QUIT to make the loop interruptible.
9887 2012-06-29 Glenn Morris <rgm@gnu.org>
9889 * charset.c (init_charset): Make lack of etc/charsets fatal.
9891 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9893 * editfns.c (region_limit): Fix type mismatch.
9895 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9897 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9898 undefined. Convert from xassert to eassert.
9899 * nsmenu.m: Convert from xassert to eassert.
9900 * nsterm.m: Likewise.
9902 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9904 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9906 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9908 Avoid integer overflow on scroll-left and scroll-right.
9909 * window.c (HSCROLL_MAX): New macro.
9910 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9911 overflow when requested scroll falls outside ptrdiff_t range.
9913 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9915 * window.h (struct window): Change type of 'hscroll',
9916 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9917 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9918 Adjust users accordingly.
9919 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9920 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9921 from EMACS_INT to ptrdiff_t.
9922 (make_window): Omit redundant initialization.
9924 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9926 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9928 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9930 * window.h (struct window): Change type of 'use_time' and
9931 'sequence_number' from Lisp_Object to int.
9932 * frame.c (make_frame): Adjust users accordingly.
9933 * print.c (print_object): Likewise.
9934 * window.c (select_window, Fwindow_use_time, make_parent_window)
9935 (make_window): Likewise.
9937 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9939 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9940 enabled with --enable-checking=[all,glyphs] configure option.
9941 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9942 adjust comments accordingly.
9943 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
9944 undefined, adjust comments accordingly.

9954 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

10065 Use sprintf return value instead of invoking strlen on result.
10066 In the old days this wasn't portable, since some sprintf
10067 implementations returned char *. But they died out years ago and
10068 Emacs already assumes sprintf returns int.
10069 Similarly for float_to_string.

10078 Use sprintf or float_to_string result to avoid need to call strlen.
10079 * data.c (Fnumber_to_string):
10080 Use make_unibyte_string, since the string must be ASCII.
10081 * lisp.h, print.c (float_to_string): Now returns int length.
10082 * term.c (produce_glyphless_glyph):
10083 Use sprintf result rather than recomputing it.

10118 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10187 This improves on the previous patch, which introduced a bug
10188 when time_t is unsigned and as wide as intmax_t.
10189 See <http://bugs.gnu.org/9000#51>.

10220 language ID in the event parameters.
10222 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10223 event.code, not the obscure "character set ID".
10225 2012-06-23 Chong Yidong <cyd@gnu.org>

10254 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10256 Support higher-resolution time stamps (Bug#9000).
10257 The time stamps are only nanosecond-resolution at the C level,
10258 since that's the best that any real-world system supports now.
10259 But they are picosecond-resolution at the Lisp level, as that's
10260 easy, and leaves room for future OS improvements.
10262 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10265 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10266 Don't get current time unless it's needed.
10268 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10269 now provides it if it's absent.
10270 (start_atimer): Port to higher-res time stamps.
10271 Check for time stamp overflow. Don't get current time more
10272 often than is needed.
10274 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10275 Include systime.h, not time.h.
10276 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10278 * dired.c: Include stat-time.h.
10279 (Ffile-attributes): File times now have higher resolution.
10281 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10282 (struct image): Timestamp now has higher resolution.
10284 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10285 has at least microseconds now. All uses removed.
10286 (update_frame, update_single_window, update_window, update_frame_1)
10287 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10288 (duration_to_sec_usec): Remove; no longer needed.
10290 * editfns.c (time_overflow): Now extern.
10291 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10292 (float-time, Fformat_time_string, Fcurrent_time_string)

10296 (decode_time_components, lisp_seconds_argument): New functions.
10297 (make_time): Now static.
10298 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10299 Report an error if the time is invalid, rather than having the caller
10302 * fileio.c: Include <stat-time.h>
10303 (Fcopy_file): Copy higher-resolution time stamps.
10304 Prefer to set the time stamp via a file descriptor if that works.
10305 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10306 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10307 (Fvisited_file_modtime, Fset_visited_file_modtime):
10308 Support higher-resolution time stamps.
10310 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10312 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10314 * image.c (prepare_image_for_display, clear_image_cache)
10315 (lookup_image): Port to higer-resolution time stamps.
10317 * keyboard.c (start_polling, bind_polling_period):
10318 Check for time stamp overflow.
10319 (read_char, kbd_buffer_get_event, timer_start_idle)
10320 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10321 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10322 Port to higher-resolution time stamps. Do not assume time_t is signed.
10323 (decode_timer): New function. Timers are now vectors of length 9,
10324 not 8, to accommodate the picosecond component.
10325 (timer_check_2): Use it.
10327 * nsterm.m (select_timeout, timeval_subtract): Remove.
10328 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10329 as they're a bit more accurate and handle overflow better.
10330 (ns_select): Change prototype to be compatible with pselect.
10331 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10332 * nsterm.h (ns_select): Adjust prototype.
10334 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10335 us-resolution time stamps.
10336 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10338 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10340 * lisp.h (time_overflow): New decl.
10341 (wait_reading_process_output): First arg is now intmax_t, not int,
10342 to accommodate larger waits.
10344 * process.h (struct Lisp_Process.read_output_delay):
10345 Now counts nanoseconds, not microseconds.
10346 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10348 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10349 (wait_reading_process_output):
10350 Port to ns-resolution time stamps.
10351 (Faccept_process_output, wait_reading_process_output):
10352 Check for time stamp overflow. Do not assume time_t is signed.
10353 (select_wrapper): Remove; we now use pselect.
10354 (Fprocess_attributes): Now generates ns-resolution time stamps.
10356 * sysdep.c: Include utimens.h. Don't include utime.h
10357 or worry about struct utimbuf; gnulib does that for us now.
10358 (gettimeofday): Remove; gnulib provides a substitute.
10359 (make_timeval): New function.
10360 (set_file_times): Now sets ns-resolution time stamps.
10361 New arg FD; all uses changed.
10362 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10363 (system_process_attributes):
10364 Now returns ns-resolution time stamp. All uses changed.
10365 Check for time stamp overflow.
10367 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10368 provides a substitute now.
10370 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10371 since it guarantees struct timespec.
10372 (EMACS_TIME): Now struct timespec, so that we can support
10373 ns-resolution time stamps.
10374 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10375 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10376 (EMACS_USECS): Remove.
10377 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10378 so multiply the arg by 1000 before storing it.
10379 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10381 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10382 Port to ns-resolution time stamps.
10383 (EMACS_TIME_NEG_P): Remove; replaced by....
10384 (EMACS_TIME_SIGN): New macro.
10385 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10386 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10387 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10388 (make_timeval, make_lisp_time, decode_time_components): New decls.
10389 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10390 that it mishandled time_t overflow. You can't compare by subtracting!
10391 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10392 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10394 * term.c: Include <sys/time.h>.
10395 (timeval_to_Time): New function, for proper overflow wraparound.
10396 (term_mouse_position, term_mouse_click): Use it.
10398 * undo.c (record_first_change): Support higher-resolution time stamps
10399 in the undo buffer.
10400 (Fprimitive_undo): Use them when restoring time stamps.
10402 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10403 (w32_get_internal_run_time):
10404 Port to higher-resolution Emacs time stamps.
10405 (ltime): Now accepts single 64-bit integer, as that's more convenient
10408 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10410 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10411 for compatibility with pselect. Support ns-resolution time stamps.
10413 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10415 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10416 Check for time stamp overflow, and support ns-resolution time stamps.
10418 * xterm.c: Don't include sys/time.h; gnulib does that for us now.

10431 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10432 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10433 staticidx goes up to 1597 out of 1600 = 0x640.)

10708 Use an inline function on all platforms when using the union type,

10854 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10855 would mishandle a string argument "Xc" if X was a multibyte
10856 character of length 2: it would truncate after X's first byte
10857 rather than including all of X.
10859 2012-06-06 Chong Yidong <cyd@gnu.org>

10871 2012-06-03 Ulrich Müller <ulm@gentoo.org>
10873 * Makefile.in (PAXCTL): Define.
10874 (temacs$(EXEEXT)): Disable memory randomization for the temacs
10875 binary via PaX flags if the paxctl utility is available.
10876 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10877 Restore PaX flags to their default. (Bug#11398)
10879 2012-06-03 Chong Yidong <cyd@gnu.org>
10881 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10882 buffer (Bug#11226).
10884 2012-06-03 Chong Yidong <cyd@gnu.org>
10886 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
10887 (note_mode_line_or_margin_highlight): If there is no help echo,
10888 use mode-line-default-help-echo. Handle the case where the mouse
10889 position is past the end of the mode line string.
10891 * buffer.c (buffer_local_value_1): New function, split from
10892 Fbuffer_local_value; can return Qunbound.
10893 (Fbuffer_local_value): Use it.
10894 (Vmode_line_format): Docstring tweaks.
10896 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10908 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10910 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10911 Convert pctcpu and pctmem to Lisp float properly.
10912 Let the compiler fold better, as 100.0/0x8000 is exact.
10914 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10916 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10919 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10923 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10925 For a 'struct window', replace some Lisp_Object fields to
10926 bitfields where appropriate, remove unused fields.
10927 * window.h (struct window): Remove unused 'last_mark_x' and
10928 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10929 change its type from Lisp_Object to bitfield.
10930 Change type of 'force_start', 'optional_new_start',
10931 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10932 fields from Lisp_Object to bitfield. Adjust users accordingly.
10934 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10936 Pacify gcc -Wdouble-precision when using Xaw.
10937 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10938 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10939 Use 'float' consistently, rather than 'float' in most places
10940 and 'double' in a couple of places.
10942 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10944 * xdisp.c (handle_stop): Detect whether we have overlay strings
10945 loaded by testing it->current.overlay_string_index to be
10946 non-negative, instead of checking whether n_overlay_strings is
10947 positive. (Bug#11587)
10949 2012-05-31 Chong Yidong <cyd@gnu.org>
10951 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10953 * doc.c (Fsubstitute_command_keys): Doc fix.
10955 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10957 * search.c (search_buffer): Remove calls to
10958 r_alloc_inhibit_buffer_relocation, as it is now called by
10959 maybe_unify_char, which was the cause of relocation of buffer text
10962 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10964 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10965 for the duration of call to load_charset, to avoid problems with
10966 callers of maybe_unify_char that access buffer text through C
10969 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10970 decrement the inhibition flag, instead of just setting or
10973 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10975 Remove obsolete '#define static' cruft.
10976 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10977 This #undef was "temporary" in 2000; it is no longer needed
10978 now that '#define static' has gone away.
10979 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10980 (gray_bitmap_bits): Remove; no longer needed.
10981 All uses replaced with definiens.
10982 * xterm.c: Include "bitmaps/gray.xbm".
10984 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10986 Clean up __executable_start, monstartup when --enable-profiling.
10987 The following changes affect the code only when profiling.
10988 * dispnew.c (__executable_start): Rename from safe_bcopy.
10989 Define only on platforms that need it.
10990 * emacs.c: Include <sys/gmon.h> when profiling.
10991 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10992 (__executable_start): Remove decl, since lisp.h does it now.
10993 (safe_bcopy): Remove decl; no longer has that name.
10994 (main): Coalesce #if into single bit of code, for simplicity.
10995 Cast pointers to uintptr_t, since standard libraries want integers
10997 * lisp.h (__executable_start): New decl.
10999 2012-05-31 Glenn Morris <rgm@gnu.org>
11001 * image.c (Fimagemagick_types): Doc fix.
11003 2012-05-30 Jim Meyering <meyering@redhat.com>
11005 * callproc.c (Fcall_process_region): Include directory component

11018 (Qdefun): Move from eval.c.
11019 * lisp.h (Qdefun): Remove.
11020 * lread.c (read1): Tiny simplification.
11022 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11024 Do not create empty overlays with the evaporate property (Bug#9642).
11025 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11026 Bug#9642, but explicitly check that the buffer the overlay would
11027 be moved to is live and rearrange lines to make sure that errors
11028 will not put the overlay in an inconsistent state.
11029 (Fdelete_overlay): Cosmetics.
11031 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11033 * w32term.c (my_bring_window_to_top): New function.
11034 (x_raise_frame): Use handle returned by DeferWindowPos, which
11035 could be different from the original one.
11036 Call my_bring_window_to_top instead of my_set_foreground_window.
11039 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
11040 by calling BringWindowToTop.

11045 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11047 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11048 This avoids undefined behavior that might cause the eassert
11049 to not catch an out-of-range value.
11051 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11053 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11054 Update dependencies.
11056 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11058 * bidi.c (bidi_mirror_char): Fix last change.
11060 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
11062 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
11063 when referring to sectname field in printf format.
11065 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11067 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11068 Only r_alloc_inhibit_buffer_relocation needed to be added;
11069 the others were already declared.
11071 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11072 before checking whether it's out of range. Put the check inside
11074 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11076 2012-05-27 Ken Brown <kbrown@cornell.edu>
11078 * callproc.c (Fcall_process): Restore a line that was accidentally
11079 commented out in the 2011-02-13 change (bug#11547).
11081 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11083 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11084 defined on ralloc.c.
11086 * buffer.c [REL_ALLOC]: Remove prototypes of
11087 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11088 they are now on lisp.h.
11090 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11092 * search.c (search_buffer): Use it to inhibit relocation of buffer
11093 text while re_search_2 is doing its job, because re_search_2 is
11094 passed C pointers to buffer text. (Bug#11519)
11096 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11097 Update value to 24.
11099 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11100 state after an additional call to move_it_in_display_line_to, keep
11101 the values of it->max_ascent and it->max_descent found for the
11103 (pos_visible_p): Revert the comparison against bottom_y to what it
11104 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11107 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11109 Fix coding-related core dumps with gcc -ftrapv.
11110 The code was computing A - B, where A and B are pointers, and B is
11111 random garbage. This can lead to core dumps on platforms that
11112 have special pointer registers, and it also leads to core dumps on
11113 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11114 A - B only when B is initialized properly.
11115 * coding.c (coding_set_source, coding_set_destination): Return void.
11116 (coding_change_source, coding_change_destinations): New functions,
11117 with the old behaviors of coding_set_source and coding_set_destination.
11118 All callers that need an offset changed to use these new functions.
11120 2012-05-26 Glenn Morris <rgm@gnu.org>
11122 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11124 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11126 Extend mouse support on W32 text-mode console.
11127 * xdisp.c (draw_row_with_mouse_face):
11128 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11130 * w32console.c: Include window.h.
11131 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11133 (initialize_w32_display): Initialize mouse-highlight data.
11135 * w32inevt.c: Include termchar.h and window.h.
11136 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11137 moves, call note_mouse_highlight. If help_echo changed, call
11138 gen_help_event to produce help-echo message in the echo area.
11139 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11142 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11144 * lread.c (read1): Simplify slightly to avoid an overflow warning
11145 with GCC 4.7.0 on x86-64.
11147 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11149 * bidi.c (bidi_mirror_char): Revert last change: an int is
11150 definitely wide enough here.
11152 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11154 Fix integer width and related bugs (Bug#9874).
11155 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11156 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11157 (string_bytes, check_sblock, allocate_string_data):
11158 (compact_small_strings, Fmake_bool_vector, make_string)
11159 (make_unibyte_string, make_multibyte_string)
11160 (make_string_from_bytes, make_specified_string)
11161 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11162 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11164 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11165 (allocate_pseudovector):
11166 Use int, not EMACS_INT, where int is wide enough.
11167 (inhibit_garbage_collection, Fgarbage_collect):
11168 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11169 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11170 int might not be wide enough.
11171 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11172 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11173 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11174 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11175 (bidi_level_of_next_char, bidi_move_to_visually_next):
11176 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11177 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11178 (Fkill_buffer, Fset_buffer_major_mode)
11179 (advance_to_char_boundary, Fbuffer_swap_text)
11180 (Fset_buffer_multibyte, overlays_at, overlays_in)
11181 (overlay_touches_p, struct sortvec, record_overlay_string)
11182 (overlay_strings, recenter_overlay_lists)
11183 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11184 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11185 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11186 (Foverlay_recenter, last_overlay_modification_hooks_used)
11187 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11188 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11189 (validate_region): Omit unnecessary test for b <= e,
11190 since that's guaranteed by the previous test.
11191 (adjust_overlays_for_delete): Avoid pos + length overflow.
11192 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11193 (report_overlay_modification):
11194 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11195 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11196 Omit pointer cast, which isn't needed anyway, and doesn't work
11197 after the EMACS_INT -> ptrdiff_t change.
11198 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11199 * buffer.h: Adjust decls to match defn changes elsewhere.
11200 (struct buffer_text, struct buffer):
11201 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11202 Use EMACS_INT, not int, where int might not be wide enough.
11203 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11204 not int, to avoid needless 32-bit limit on 64-bit hosts.
11205 (exec_byte_code): Use tighter memory-full test, one that checks
11206 for alloca overflow. Don't compute the address of the object just
11207 before an array, as that's not portable. Use EMACS_INT, not
11208 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11209 * callint.c (Fcall_interactively):
11210 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11211 * callproc.c (call_process_kill, Fcall_process):
11212 Don't assume pid_t fits into an Emacs fixnum.
11213 (call_process_cleanup, Fcall_process, child_setup):
11214 Don't assume pid_t fits into int.
11215 (call_process_cleanup, Fcall_process, delete_temp_file)
11216 (Fcall_process_region):
11217 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11218 (Fcall_process): Simplify handling of volatile integers.
11219 Use int, not EMACS_INT, where int will do.
11220 * casefiddle.c (casify_object, casify_region, operate_on_word)
11221 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11222 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11223 (casify_object): Avoid integer overflow when overallocating buffer.
11224 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11225 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11226 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11227 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11228 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11229 integers are now checked earlier. All uses replaced with XINT.
11231 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11232 For CCL_MapSingle, check that content and value are in int range.
11233 (ccl_driver, Fregister_code_conversion_map):
11234 Check that Vcode_version_map_vector is a vector.
11235 (resolve_symbol_ccl_program): Check that vector header is in range.
11236 Always copy the vector, so that we can check its contents reliably
11237 now rather than having to recheck each instruction as it's being
11238 executed. Check that vector words fit in 'int'.
11239 (ccl_get_compiled_code, Fregister_ccl_program)
11240 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11241 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11242 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11243 contents are in range.
11244 (Fccl_execute_on_string): Check that status is in range.
11245 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11246 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11247 Accept and return EMACS_INT, not int, because callers can pass values
11248 out of 'int' range.
11249 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11250 (multibyte_chars_in_text, parse_str_as_multibyte)
11251 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
11252 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11253 (string_escape_byte8, Fget_byte):
11254 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11255 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11256 avoid mishandling large integers.
11257 * character.h: Adjust decls to match defn changes elsewhere.
11258 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11259 (Ffind_charset_region):
11260 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11261 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11262 (load_charset_map_from_vector, Fdefine_charset_internal):
11263 Don't assume fixnum fits in int.
11264 (load_charset_map_from_vector, Fmap_charset_chars):
11265 Remove now-unnecessary CHECK_NATNUMs.
11266 (Fdefine_charset_internal): Check ranges here, more carefully.
11267 Don't rely on undefined behavior with signed left shift overflow.
11268 Don't assume unsigned int fits into fixnum, or that fixnum fits
11269 into unsigned int. Don't require max_code to be a valid fixnum;
11270 that's not true for gb10830 4-byte on a 32-bit host. Allow
11271 invalid_code to be a cons, for the same reason. Require code_offset
11272 to be a character. Avoid int overflow if max_char is close
11274 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11275 this is intended anyway and avoids some undefined behavior.
11276 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11277 INDEX_TO_CODE_POINT, as that's what it expects.
11278 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11279 * charset.h (DECODE_CHAR): Return int, not unsigned;
11280 this is what was intended anyway, and it avoids undefined behavior.
11281 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11282 integer-overflow issues.
11283 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.

11952 (SCROLL_BAR_VEC_SIZE): Remove; not used.
11954 2012-05-25 Glenn Morris <rgm@gnu.org>
11956 * lisp.mk (lisp): Update for more files being compiled now.
11958 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11960 * lread.c: Remove `read_pure' which makes no difference.
11961 (read_pure): Remove var.
11962 (unreadpure): Remove function.
11963 (readevalloop): Don't call read_list with -1 flag.
11964 (read1, read_vector): Don't test read_pure any more.
11965 (read_list): Simplify.
11967 * fileio.c, character.h: Minor style tweaks.
11969 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
11971 * window.h (clip_changed): Remove useless declaration.
11973 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11975 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11976 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11978 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11981 This directory predates autoconf and is no longer needed nowadays.
11982 Move its few remaining bits of functionality to where they're needed.
11983 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11984 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11985 * m/template.h: Remove.
11986 * Makefile.in (M_FILE): Remove. All uses removed.
11987 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11988 * lisp.h (USE_LSB_TAG):
11989 * mem-limits.h (EXCEEDS_LISP_PTR):
11990 Use VAL_MAX, not VALBITS, in #if.
11991 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11992 (EMACS_UINT): Define unconditionally now.
11993 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11994 (BITS_PER_EMACS_INT): New constants, replacing
11995 what used to be in config.h, but not useful in #if.
11996 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11997 define them any more.
11998 (VAL_MAX): New macro.
12000 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12001 BITS_PER_EMACS_INT, in #if.
12002 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12003 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12004 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12005 * s/ms-w32.h (DATA_START):
12006 Move here from removed file m/intel386.h.
12007 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12008 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12010 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12012 Assume C89 or later.
12013 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12014 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12016 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12017 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12018 * textprop.c, tparam.c (NULL): Remove.
12019 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12020 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12021 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12022 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12023 * xterm.c (input_signal_count): Assume volatile works.
12025 2012-05-21 Ken Brown <kbrown@cornell.edu>
12027 * xgselect.c (xg_select): Fix first argument in call to 'select'
12030 2012-05-20 Ken Brown <kbrown@cornell.edu>
12032 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12033 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12035 2012-05-19 Ken Brown <kbrown@cornell.edu>
12037 * xfns.c (x_in_use): Remove `static' qualifier.
12038 * xterm.h (x_in_use): Declare.
12039 * xgselect.c: Include xterm.h.
12040 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12041 and `display_arg' (bug#9754).
12043 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12045 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12047 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12048 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12050 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12052 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12054 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12055 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12057 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12058 reference to image_cache->refcount.
12059 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12061 2012-05-17 Juri Linkov <juri@jurta.org>
12063 * search.c (Fword_search_regexp, Fword_search_backward)
12064 (Fword_search_forward, Fword_search_backward_lax)
12065 (Fword_search_forward_lax): Move functions to isearch.el
12066 (bug#10145, bug#11381).
12068 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12070 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12072 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12074 * lread.c (init_obarray): Declare Qt and Qnil as special.
12076 2012-05-14 Glenn Morris <rgm@gnu.org>
12078 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12079 Put "libexec" before "bin", for the sake of init_callproc_1.
12081 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12083 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12085 * unexaix.c: Port to more-recent AIX compilers.
12086 (report_error, report_error_1, make_hdr, copy_sym)
12087 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12088 Make arguments const char *, not char *, to avoid violations of C
12089 standard and to fix some AIX warnings reported by Gilles Pion.
12091 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12093 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12094 already have overlays loaded.
12095 (handle_single_display_spec): Before returning without displaying
12096 fringe bitmap, synchronize the bidi iterator with the main display
12097 iterator, by calling iterate_out_of_display_property.
12098 (iterate_out_of_display_property): Detect buffer iteration by
12099 testing that it->string is a Lisp string.
12100 (get_next_display_element): When the current object is exhausted,
12101 and there's something on it->stack, call set_iterator_to_next to
12102 proceed with what's on the stack, instead of returning zero.
12103 (set_iterator_to_next): If called at the end of a Lisp string,
12104 proceed to consider_string_end without incrementing string
12105 position. Don't increment display vector index past the end of
12106 the display vector. (Bug#11417)
12107 (pos_visible_p): Don't report a position visible when move_it_to
12108 stopped at the last line of window, which happens to be scanned
12109 backwards by the bidi iteration. (Bug#11464)
12111 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12113 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12114 and right-margin display specs even if the spec is invalid or we
12115 are on a TTY, and thus unable to display on the fringes.
12116 That's because the text with the property will not be displayed anyway,
12117 so we need to signal to the caller that this is a "replacing"
12118 display spec. This fixes display when the spec is invalid or we
12121 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12123 * unexaix.c (make_hdr): Fix typo in prototype.
12124 This bug broke the build on AIX. Problem reported by Gilles Pion.
12126 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12128 * keyboard.c (kbd_buffer_get_event): Read special events also in
12129 batch mode. (Bug#11415)
12131 2012-05-12 Glenn Morris <rgm@gnu.org>
12133 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12135 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12137 * lisp.mk (lisp): Add newcomment.elc.
12139 2012-05-12 Glenn Morris <rgm@gnu.org>
12141 * Makefile.in (MKDIR_P): New, set by configure.
12142 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12144 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12146 Remove unused function hourglass_started.
12147 * dispextern.h (hourglass_started):
12148 * w32fns.c (hourglass_started):
12149 * xdisp.c (hourglass_started): Remove.
12151 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12153 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12154 Update dependencies.
12156 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12158 * xgselect.c (xg_select): Put maxfds+1 into a var.
12159 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12161 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12163 2012-05-10 Dave Abrahams <dave@boostpro.com>
12165 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12166 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12168 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12170 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12171 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12172 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12173 Initialize xd_registered_buses.
12175 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12177 Untag more efficiently if USE_LSB_TAG.
12178 This is based on a proposal by YAMAMOTO Mitsuharu in
12179 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12180 For an admittedly artificial (nth 8000 longlist) benchmark on
12181 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12182 Emacs's overall text size by 1%.
12183 * lisp.h (XUNTAG): New macro.
12184 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12185 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12186 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12187 * eval.c (Fautoload):
12188 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12189 * frame.h (XFRAME): Use XUNTAG.
12191 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12192 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12193 Remove unportable assumptions about print widths of types like
12195 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12196 intptr_t when converting between pointer and integer, to avoid GCC
12197 warnings about wrong width.
12199 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12201 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12202 stack for each reader_thread, instead of defaulting to 8MB
12203 determined by the linker. This avoids failures in creating
12204 subprocesses on Windows 7, see the discussion in this thread:
12205 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12207 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12209 Fix up display of the *Minibuf-0* buffer in the mini window.
12210 * keyboard.c (read_char): Don't clear the echo area if there's no
12212 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12213 contents of *Minibuf-0*) if there's no message displayed in its stead.
12215 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12217 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12220 2012-05-06 Chong Yidong <cyd@gnu.org>
12222 * lisp.mk (lisp): Update.
12224 2012-05-05 Jim Meyering <meyering@redhat.com>
12226 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12228 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12230 * data.c (PUT_ERROR): New macro.
12231 (syms_of_data): Use it. Add new error type `user-error'.
12232 * undo.c (user_error): New function.
12233 (Fprimitive_undo): Use it.
12234 * print.c (print_error_message): Adjust print style for `user-error'.
12235 * keyboard.c (user_error): New function.
12236 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12238 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12240 Do not limit current-time-string to years 1000..9999.
12241 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12242 (Fcurrent_time_string): Support any year that is supported by the
12243 underlying localtime representation. Don't use asctime, as it
12244 has undefined behavior for years outside the range -999..9999.
12246 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12248 Fix race conditions involving setenv, gmtime, localtime, asctime.
12249 Without this fix, interrupts could mess up code that uses these
12250 nonreentrant functions, since setting TZ invalidates existing
12251 tm_zone or tzname values, and since most of these functions return
12252 pointers to static storage.
12253 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12254 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12255 Grow the critical sections to include not just invoking
12256 localtime/gmtime, but also accessing these functions' results
12257 including their tm_zone values if any, and any related TZ setting.
12258 (format_time_string): Last arg is now struct tm *, not struct tm **,
12259 so that the struct tm is saved in the critical section.
12260 All callers changed. Simplify allocation of initial buffer, partly
12261 motivated by the fact that memory allocation needs to be outside
12262 the critical section.
12264 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12266 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12267 with RESET_INTERVAL.
12269 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12270 Remove duplicated buffer name initialization.
12272 2012-05-02 Jim Meyering <jim@meyering.net>
12274 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12276 * xfns.c (x_window): Use xstrdup (Bug#11375).
12278 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12280 * xdisp.c (pos_visible_p): If already at a newline from the
12281 display string before the 'while' loop, don't walk back the glyphs
12282 from it3.glyph_row. Solves assertion violation when the display
12283 string begins with a newline (egg.el). (Bug#11367)
12285 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12287 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12290 2012-05-01 Glenn Morris <rgm@gnu.org>
12292 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12293 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12294 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12295 All were removed before 23.1.
12297 * dispnew.c: Remove HAVE_LIBNCURSES test;
12298 it is always true on relevant platforms.
12300 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12301 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12303 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12305 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12307 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12308 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12311 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12313 Do not avoid creating empty evaporating overlays (Bug#9642).
12314 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12315 That is, do not delete an evaporating overlay if it becomes
12316 empty after its bounds are adjusted to fit within its buffer.
12317 This fix caused other problems, and I'm reverting it until we get
12318 to the bottom of them.
12320 2012-04-27 Chong Yidong <cyd@gnu.org>
12322 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12324 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12326 * xdisp.c (pos_visible_p): If the window start position is beyond
12327 ZV, start the display from buffer beginning. Prevents assertion
12328 violation in init_iterator when the minibuffer window is scrolled
12329 via the scroll bar.
12331 * window.c (window_scroll_pixel_based): Likewise.
12333 2012-04-27 Chong Yidong <cyd@gnu.org>
12335 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12337 2012-04-27 Glenn Morris <rgm@gnu.org>
12339 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12340 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12342 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12344 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12345 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12347 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12349 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12350 display element, check also the underlying string or buffer
12351 character. (Bug#11341)
12353 * w32menu.c: Include w32heap.h.
12354 (add_menu_item): If the call to AppendMenuW (via
12355 unicode_append_menu) fails, disable Unicode menus only if we are
12356 running on Windows 9X/Me.
12358 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12360 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12361 (xgetint): Add missing shift for LSB tags.
12363 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12365 * keyboard.c (read_char): Don't wipe echo area for select window
12366 events: These might get delayed via `mouse-autoselect-window'
12369 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12371 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12372 manipulation of :loaded-from data.
12374 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12376 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12377 now a cons (bug#11311).
12379 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12381 Do not create empty overlays with the evaporate property (Bug#9642).
12382 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12383 if it becomes empty after its bounds are adjusted to fit within
12384 its buffer. Without this fix, in a nonempty buffer (let ((o
12385 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12386 yields an empty overlay that has the evaporate property, which is
12387 not supposed to happen.
12389 Fix minor GTK3 problems found by static checking.
12390 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12391 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12392 (struct _EmacsFixedClass, emacs_fixed_get_type):
12393 Move decls here from emacsgtkfixed.h, since they needn't be public.
12394 (emacs_fixed_get_type): Now static.

12591 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12592 (NEED_MEM_INSERT): New macro.
12593 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12594 Remove one incorrect comment and fix another.

12661 2012-04-11 Daniel Colascione <dancol@dancol.org>
12663 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12664 against is gone. It's better to use vfork now so that when Cygwin
12665 gains a new, working vfork, we use it automatically (bug#10398).
12667 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12720 * minibuf.c (Fread_variable): Callers changed.
12722 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12724 * xdisp.c (set_cursor_from_row): If the display string appears in
12725 the buffer at position that is closer to point than the position
12726 after the display string, display the cursor on the first glyph of
12727 the display string. Fixes cursor display when a 'display' text
12728 property immediately follows invisible text. (Bug#11094)
12730 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12732 composite.c: use 'double' consistently
12733 * composite.c (get_composition_id): Use 'double' consistently
12734 instead of converting 'float' to 'double' and vice versa; this is
12735 easier to understand and avoids a GCC warning.
12737 2012-04-09 Glenn Morris <rgm@gnu.org>

12789 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12791 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

12804 point, use it.vpos to compute how many lines to backtrack after
12805 move_it_to point. (Bug#11133)
12807 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12809 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12810 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12811 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12812 macros related to unification of CJK characters. For the details,
12813 see the discussion following the message here:

12827 * w32menu.c (is_simple_dialog): Properly check lisp types.
12830 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12832 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12833 position we get to after a call to move_it_to fails the
12834 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12835 only if we wind up in a string from display property. (Bug#11063)
12837 * window.c (Fdelete_other_windows_internal): Invalidate the row
12838 and column information about mouse highlight, so that redisplay
12839 restores it after reallocating the glyph matrices. (Bug#7464)
12841 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12842 string comes from a `display' text property, use the buffer
12843 position of that property as if we actually saw that position in
12845 (move_it_by_lines): Remove the assertion that
12846 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12847 violated when there's a before-string at the beginning of a line.
12850 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12852 * xdisp.c (append_space_for_newline): If the default face was
12853 remapped, use the remapped face for the appended newline.
12854 (extend_face_to_end_of_line): Use the remapped default face for
12855 extending the face to the end of the line.
12856 (display_line): Call extend_face_to_end_of_line when the default
12857 face was remapped. (Bug#11068)
12859 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12861 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12863 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12865 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12867 2012-03-27 Glenn Morris <rgm@gnu.org>
12869 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12872 2012-03-26 Kenichi Handa <handa@m17n.org>
12874 * dispextern.h (struct glyph): Fix previous change. Change the
12875 bit length of glyphless.ch to 25 (Bug#11082).
12877 2012-03-26 Chong Yidong <cyd@gnu.org>
12879 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12880 (command_loop_1): Use it; inhibit selection update for
12881 handle-select-window too (Bug#8996).
12883 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12885 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12887 2012-03-25 Kenichi Handa <handa@m17n.org>
12889 * dispextern.h (struct glyph): Change the bit length of
12890 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12892 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12894 * s/ms-w32.h (tzname): Include time.h before redirecting to
12895 _tzname. Fixes the MSVC build. (Bug#9960)
12897 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12899 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12902 * xterm.c (XTread_socket): Only modify handling_signal if
12903 !SYNC_INPUT. (Bug#11080)
12905 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12907 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12908 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12909 when fetching a multibyte character consumes more bytes than
12910 CHAR_BYTES returns, due to unification of CJK characters in
12911 string_char. (Bug#11073)
12913 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12915 * process.c (wait_reading_process_output): Handle pty disconnect
12916 by refraining from sending oneself a SIGCHLD (bug#10933).
12918 2012-03-22 Chong Yidong <cyd@gnu.org>
12920 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12922 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12923 Mark string as coming from a prefix property.
12924 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12925 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12927 2012-03-21 Chong Yidong <cyd@gnu.org>
12929 * xfaces.c (Vface_remapping_alist): Doc fix.
12931 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12933 * w32proc.c (Fw32_set_console_codepage)
12934 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12937 2012-03-20 Chong Yidong <cyd@gnu.org>
12939 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12940 to reflect default non-nil value of redisplay-dont-pause.
12942 2012-03-19 Kenichi Handa <handa@m17n.org>
12944 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12945 it fit in a valid range (Bug#11003).
12947 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12949 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12950 that is not from display property, accept the row as a "cursor
12951 row" if one of the string's character has a non-nil `cursor'
12952 property. Fixes cursor positioning when there are newlines in
12953 overlay strings, e.g. in icomplete.el. (Bug#11035)
12955 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12957 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12959 2012-03-12 Chong Yidong <cyd@gnu.org>
12961 * eval.c (inhibit_lisp_code): Rename from
12962 inhibit_window_configuration_change_hook; move from window.c.
12964 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12965 * window.c (run_window_configuration_change_hook)
12966 (syms_of_window): Callers changed.
12968 2012-03-11 Chong Yidong <cyd@gnu.org>

12972 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12974 2012-03-10 Chong Yidong <cyd@gnu.org>
12976 * frame.c (other_visible_frames): Don't assume the selected frame
12977 is visible (Bug#10955).
12979 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12981 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12983 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12985 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12986 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12989 2012-03-03 Glenn Morris <rgm@gnu.org>
12991 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12993 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12995 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12996 position past the first glyph_row that ends at ZV. (Bug#10902)
12997 (redisplay_window, next_element_from_string): Fix typos in
12999 (redisplay_window): Pass to move_it_vertically the margin in
13000 pixels, not in screen lines.
13002 2012-03-02 Glenn Morris <rgm@gnu.org>
13004 * buffer.c (buffer-list-update-hook): Doc fix.
13006 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13008 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13009 push_it before setting up the iterator for the first overlay
13010 string, even if we have an empty string loaded.
13011 (next_overlay_string): If there's an empty string on the iterator
13012 stack, pop the stack. (Bug#10903)
13014 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13016 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13017 Suggested by Stefan Monnier in
13018 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13019 * alloc.c (widen_to_Lisp_Object): New static function.
13020 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13021 and widening them to Lisp_Objects. This would work even if
13022 USE_LSB_TAG is defined and wide integers are used, which might
13023 happen in a future version of Emacs.
13025 2012-02-25 Chong Yidong <cyd@gnu.org>
13027 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13030 * xselect.c (Fx_selection_exists_p): Doc fix.
13031 (x_clipboard_manager_save_all): Print an informative message
13032 before saving to clipboard manager.
13034 2012-02-24 Chong Yidong <cyd@gnu.org>
13036 * keyboard.c (process_special_events): Handle all X selection
13037 requests in kbd_buffer, not just the next one (Bug#8869).
13039 2012-02-23 Chong Yidong <cyd@gnu.org>
13041 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13042 call when setting menu-bar-lines and tool-bar-lines parameters.
13043 (unwind_create_frame_1): New helper function.
13045 * window.c (inhibit_window_configuration_change_hook): New var.
13046 (run_window_configuration_change_hook): Obey it.
13047 (syms_of_window): Initialize it.
13049 2012-02-22 Chong Yidong <cyd@gnu.org>
13051 * xterm.c (x_draw_image_relief): Add missing type check for
13052 Vtool_bar_button_margin (Bug#10743).
13054 2012-02-21 Chong Yidong <cyd@gnu.org>
13056 * fileio.c (Vfile_name_handler_alist): Doc fix.
13058 * buffer.c (Fget_file_buffer): Protect against invalid file
13059 handler return value.
13061 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13063 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13064 when computing $valmask.
13066 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13067 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13068 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13069 It's useless in that case, and it can cause problems on hosts
13070 that allocate halves of EMACS_INT values separately.
13071 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13072 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13073 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13074 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13075 it avoids undefined behavior on hosts where shifting right by more
13076 than the word width has undefined behavior.
13078 2012-02-19 Chong Yidong <cyd@gnu.org>
13080 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13081 (Funhandled_file_name_directory, Ffile_name_as_directory)
13082 (Fdirectory_file_name, Fexpand_file_name)
13083 (Fsubstitute_in_file_name): Protect against invalid file handler
13084 return values (Bug#10845).
13086 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13088 * .gdbinit (pitx): Fix incorrect references to fields of the
13091 2012-02-17 Chong Yidong <cyd@gnu.org>

13095 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13097 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13098 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13100 2012-02-15 Chong Yidong <cyd@gnu.org>
13102 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13103 marked as special. Also, starting docstrings with * is obsolete.
13105 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13107 * gnutls.c (emacs_gnutls_write): Fix last change.
13109 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
13111 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
13114 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
13116 * keymap.c (Fsingle_key_description): Handle char ranges.
13118 2012-02-12 Chong Yidong <cyd@gnu.org>
13120 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13121 as that creates a dangerous corner case.
13123 * window.c (Fdelete_window_internal): Invalidate the mouse
13124 highlight (Bug#9904).
13126 2012-02-12 Glenn Morris <rgm@gnu.org>
13128 * xselect.c (Fx_own_selection_internal)
13129 (Fx_get_selection_internal, Fx_disown_selection_internal)
13130 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13131 * nsselect.m (Fx_own_selection_internal)
13132 (Fx_disown_selection_internal, Fx_selection_exists_p)
13133 (Fx_selection_owner_p, Fx_get_selection_internal):
13134 Sync docs and argument specs with the xselect.c versions.
13136 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13138 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13140 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13142 * w32select.c (Fx_selection_exists_p): Sync doc string and
13143 argument list with xselect.c. (Bug#10783)
13145 * w16select.c (Fx_selection_exists_p): Sync doc string and
13146 argument list with xselect.c. (Bug#10783)

13152 2012-02-09 Kenichi Handa <handa@m17n.org>
13154 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13156 2012-02-07 Chong Yidong <cyd@gnu.org>
13158 * buffer.c (Fbuffer_local_variables)
13159 (buffer_lisp_local_variables): Handle unbound vars correctly;
13160 don't let Qunbound leak into Lisp.
13162 2012-02-07 Glenn Morris <rgm@gnu.org>
13164 * image.c (Fimagemagick_types): Doc fix.
13166 * image.c (imagemagick-render-type): Change it from a lisp object
13167 to an integer. Move the doc here from the lisp manual.
13168 Treat all values not equal to 0 the same.
13170 2012-02-06 Chong Yidong <cyd@gnu.org>
13172 * doc.c (store_function_docstring): Avoid applying docstring of
13173 alias to base function (Bug#2603).

13184 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13186 * w32.c (get_emacs_configuration_options):
13187 Include --enable-checking, if specified, in the return value.
13189 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13191 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13192 after rounding frame sizes. (Bug#9723)
13194 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13196 * keyboard.c (adjust_point_for_property): Don't position point
13197 before BEGV. (Bug#10696)
13199 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13201 Handle overflow when computing char display width (Bug#9496).
13202 * character.c (char_width): Return EMACS_INT, not int.
13203 (char_width, c_string_width): Check for overflow when
13204 computing the width; this is possible now that individual
13205 characters can have unbounded width. Problem introduced
13206 by merge from Emacs 23 on 2012-01-19.
13208 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13210 * dbusbind.c (Fdbus_register_method): Mention the return value
13211 :ignore in the docstring.
13213 2012-02-02 Glenn Morris <rgm@gnu.org>
13215 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
13217 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13223 2012-02-02 Kenichi Handa <handa@m17n.org>
13225 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13226 0, do not call append_composite_glyph.
13228 2012-02-02 Kenichi Handa <handa@m17n.org>
13230 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13232 (x_produce_glyphs): If the component of a composition is a null
13233 string, set it->pixel_width to 1 to avoid zero-width glyph.
13235 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13237 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13238 first 2 arguments are identical. This makes inserting large
13239 output from a subprocess an order of magnitude faster on
13240 MS-Windows, where all sbrk'ed memory is always contiguous.
13242 2012-01-31 Glenn Morris <rgm@gnu.org>
13244 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13280 2012-01-21 Chong Yidong <cyd@gnu.org>
13282 * floatfns.c (Fcopysign): Make the second argument non-optional,
13283 since nil is not allowed anyway.
13285 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
13287 * process.c (read_process_output): Use p instead of XPROCESS (proc).
13288 (send_process): Likewise.
13290 2012-01-19 Martin Rudalics <rudalics@gmx.at>
13292 * window.c (save_window_save, Fcurrent_window_configuration)
13293 (Vwindow_persistent_parameters): Do not use Qstate.
13294 Rewrite doc-strings.
13296 2012-01-19 Kenichi Handa <handa@m17n.org>
13298 * character.c (char_width): New function.
13299 (Fchar_width, c_string_width, lisp_string_width):
13300 Use char_width (Bug#9496).
13302 2012-01-16 Martin Rudalics <rudalics@gmx.at>
13304 * window.c (Vwindow_persistent_parameters): New variable.
13305 (Fset_window_configuration, save_window_save): Handle persistent

13855 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13856 Otherwise, valgrind does not work on some platforms.
13857 Problem reported by Andreas Schwab in
13858 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13859 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13860 is set, removing the need for VIRT_ADDRESS_VARIES.
13861 (PURE_P): Use a more-efficient implementation that needs just one
13862 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13863 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13864 to 4 (xorl, subq, cmpq, setbe).
13865 * alloc.c (pure): Always extern now, since that's the
13866 VIRT_ADDR_VARIES behavior.

13868 consistency with the new puresize.h.
13869 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13870 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13876 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13877 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13878 behave as if the cursor position were at the window margin.
13880 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13881 and the cursor position is out of bounds, behave as if the cursor
13882 position were at the window margin. (Bug#10075)
13884 2011-11-18 Chong Yidong <cyd@gnu.org>
13886 * window.c (Fwindow_combination_limit): Make first argument

13908 compute_line_metrics.
13909 (compute_line_metrics): Call row_hash, instead of computing the
13912 * dispnew.c (verify_row_hash): Call row_hash for computing the
13913 hash code of a row, instead of duplicating code from xdisp.c.
13915 * dispextern.h (row_hash): Add prototype.
13917 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13953 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13955 * xdisp.c (display_line): Move the call to
13956 highlight_trailing_whitespace before the call to
13957 compute_line_metrics, since the latter needs to see the final
13958 faces of all the glyphs to compute ROW's hash value.
13959 Fixes assertion violations in row_equal_p. (Bug#10035)
13961 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13963 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13964 just return (bug#10044).
13966 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13968 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13969 with user-defined heap size. Bump the default size of the temacs
13970 heap to 27MB, to avoid memory warning when running temacs.

13973 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13974 current_matrix and desired_matrix. (Bug#9990)
13975 (verify_row_hash) [XASSERTS]: New function.

14022 Avoid some portability problems by eschewing 'extern inline' functions.
14023 The trivial performance wins aren't worth the portability hassles; see
14024 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14026 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14092 * xmenu.c (cleanup_widget_value_tree): New function.
14093 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14100 (window_box_width, window_box_left, window_box_left_offset)
14101 (window_box_right, window_box_right_offset): Declare extern.
14102 Otherwise, these inline functions do not conform to C99 and
14103 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14104 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14105 * intervals.c (adjust_intervals_for_insertion)

14108 (static_offset_intervals): Remove.
14109 (offset_intervals): Rewrite using the old contents of
14110 static_offset_intervals. The old version didn't conform to C99

14239 matrices of the partially constructed frame. (Bug#9943)
14240 * xfns.c (unwind_create_frame): Likewise.
14242 2011-11-01 Eli Zaretskii <eliz@gnu.org>
14244 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
14245 Don't stop backward scan on the continuation glyph, even though
14246 its CHARPOS is positive.
14247 (mouse_face_from_buffer_pos, note_mouse_highlight):
14248 Rename cover_string to disp_string.
14250 2011-11-01 Martin Rudalics <rudalics@gmx.at>
14252 * window.c (temp_output_buffer_show): Don't use
14253 Vtemp_buffer_show_specifiers.
14254 (Vtemp_buffer_show_specifiers): Remove unused variable.
14256 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14258 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14259 past the beginning of the current glyph matrix.
14261 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14263 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14264 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14265 HAVE_GTK3 (Bug#9869).
14267 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
14268 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14270 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14272 * xterm.c: Declare x_handle_net_wm_state to return int.
14273 (handle_one_xevent): Check if we are iconified but don't have
14274 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14275 (get_current_wm_state): Return non-zero if not hidden,
14276 check for _NET_WM_STATE_HIDDEN (Bug#9893).
14277 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
14278 (x_handle_net_wm_state): Return what get_current_wm_state returns.
14279 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
14281 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14283 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14284 so that this new function doesn't get optimized away by a
14285 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14287 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14289 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14291 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14293 Fix the `xbytecode' command.
14294 * .gdbinit (xprintbytestr): New command.
14295 (xwhichsymbols): Rename from `which'; all callers changed.
14296 (xbytecode): Print the byte-code string as well.
14298 2011-10-29 Kim Storm <storm@cua.dk>
14300 * alloc.c (which_symbols): New function.
14302 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14304 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14307 2011-10-29 Glenn Morris <rgm@gnu.org>
14309 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14310 Not clear what it was for, and it causes various bugs. (Bug#9839)
14312 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14314 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14315 possible random value that matches one of those tested as
14316 condition to clear the mouse face.
14318 2011-10-28 Chong Yidong <cyd@gnu.org>
14320 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14322 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14324 * window.c (make_window): Initialize phys_cursor_on_p.
14326 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14328 * lisp.h (struct Lisp_Symbol): Update comments.
14330 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14332 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14334 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14336 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14337 <oslsachem@gmail.com> for helping to debug this.
14339 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14340 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14341 (g_b_init_get_glyph_outline_w): New static variables.
14342 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14343 (GetGlyphOutlineW_Proc): New typedefs.
14344 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14345 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14347 (w32font_open_internal, compute_metrics):
14348 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14349 instead of calling the "wide" APIs directly.
14351 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14353 * w32.h (syms_of_w32font): Add prototype.
14355 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14357 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14358 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14359 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14360 (Fmove_to_window_line): Doc fix.
14362 2011-10-27 Chong Yidong <cyd@gnu.org>
14364 * process.c (make_process): Set gnutls_state to NULL.
14366 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14367 non-NULL, regardless of GNUTLS_INITSTAGE.
14368 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14369 an error. Set process slots as soon as we allocate them.
14371 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14373 2011-10-27 Chong Yidong <cyd@gnu.org>
14375 * gnutls.c (emacs_gnutls_deinit): New function.
14376 Deallocate credentials structures as well as calling gnutls_deinit.
14377 (Fgnutls_deinit, Fgnutls_boot): Use it.
14379 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14380 (deactivate_process): Call emacs_gnutls_deinit.
14382 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14384 * image.c (x_create_x_image_and_pixmap):
14385 * w32.c (sys_rename, w32_delayed_load):
14386 * w32font.c (fill_in_logfont):
14387 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14389 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14391 * w32fns.c (w32_default_color_map): New function,
14392 extracted from Fw32_default_color_map.
14393 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14395 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14397 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14399 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14401 * keyboard.c (test_undefined): New function (bug#9751).
14402 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14404 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14406 * sysdep.c (init_sys_modes): Fix the check for the controlling
14407 terminal (Bug#6649).
14409 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14411 * dispextern.h (struct bidi_it): New member next_en_type.
14413 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14414 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14415 current character, check also for next_en_type being WEAK_EN.
14416 (bidi_resolve_weak): Don't enter the expensive loop if the current
14417 position is before next_en_pos. Record the bidi type of the first
14418 non-ET, non-BN character we find, in addition to its position.
14419 (bidi_level_of_next_char): Invalidate next_en_type when
14420 next_en_pos is over-stepped.
14422 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14424 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14425 * editfns.c: Rewrite current-time-zone so that it invokes
14426 the equivalent of (format-time-string "%Z") to get the time zone name.
14427 This fixes a bug when the time zone name contains characters that
14428 need converting from the system time locale to Emacs internal format.
14429 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14430 that patch fixed format-time-string to do the conversion, but
14431 I forgot to fix current-time-zone.
14432 (format_time_string): New function, containing most of
14433 what Fformat_time_string used to contain.
14434 (Fformat_time_string): Rewrite in terms of format_time_string.
14435 This doesn't change this function's behavior.
14436 (current-time-zone): Rewrite to use format_time_string.
14437 This fixes the bug reported by Michael Schierl in
14438 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14439 Jason Rumney's 2007-06-07 change worked around this bug, but
14441 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14443 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14445 * xdisp.c (start_display): If the character at POS is displayed
14446 via a display vector, reset IT->current.dpvec_index to zero.
14447 (try_window_reusing_current_matrix): If a line ends in a display
14448 vector or the next line starts in a display vector, continue
14449 redrawing the window even though the character position of
14450 start_row was reached.
14453 2011-10-18 Chong Yidong <cyd@gnu.org>
14455 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14456 with nobreak-char-display too.
14458 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14460 Fix part 3 of bug#9771.
14461 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14462 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14463 non-neutral characters if the current character is a paragraph
14464 separator (a.k.a. Newline). This avoids running the same
14465 expensive loop twice, once when we consume the preceding newline
14466 and the other time when the line actually needs to be displayed.
14467 Avoid the loop when we see neutrals on the base embedding level
14468 following a character whose directionality is the same as the
14469 paragraph's. This avoids running the expensive loop when a line
14470 ends in a long sequence of neutrals, like control characters.
14471 Add assertion against STRONG_AL type. Slightly rearrange code
14472 that determines the type of a neutral given the first non-neutral
14474 (bidi_level_of_next_char): Set next_en_pos to zero when
14475 invalidating its info.
14477 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14479 * xdisp.c (push_display_prop): Determine whether to record string
14480 or buffer position by IT->string, not by IT->method. Allow
14481 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14482 (move_it_vertically_backward): Don't look for character position
14483 immediately after the newline when in a continuation line.
14486 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14488 * window.c (coordinates_in_window): Rewrite and delabelize
14489 vertical border check. (Bug#5357) (Bug#9618)
14491 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14493 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14494 errors in XSetWindowBorder (bug#9310).
14496 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14498 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14499 avoid crash when xmalloc overrun checking is enabled.
14501 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14503 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14504 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14505 cursor motion with <left> and <right> arrow keys.
14507 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14508 some callers set that themselves.
14510 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14512 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14513 display string and the previous row comes from the same string and
14514 is empty. (Bug#9739) (Bug#9738)
14516 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14518 * doc.c (get_doc_string): Encode file name (bug#9735).
14520 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14522 * bidi.c (bidi_level_of_next_char):
14523 * xdisp.c (get_visually_first_element): Remove old incorrect
14524 comments regarding the Unicode Line Separator character.
14526 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14528 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14530 * alloc.c (Fgc_status): Do not access beyond zombies array
14531 boundary if nzombies > MAX_ZOMBIES.
14532 * alloc.c (dump_zombies): Add missing format specifier.
14534 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14536 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14537 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14539 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14540 Some packages use them to denote characters with modifiers.
14542 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14544 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14545 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14546 matching a pp-number. Rename parameter var to var1.
14548 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14550 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14552 2011-10-08 Glenn Morris <rgm@gnu.org>
14554 * callint.c (Fcall_interactively): Give a more explicit error for the
14555 'c' case with a non-character input. (Bug#8479)
14557 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14559 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14561 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14562 lines that are hscrolled on the left.
14564 * dispnew.c (buffer_posn_from_coords): Account for a possible
14565 presence of header-line. (Bug#4426)
14567 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14569 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14570 Don't advertise functionality which we discourage or doesn't work.
14572 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14574 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14575 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14576 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14577 this makes Emacs dump core during garbage collection on rare
14578 occasions. sizeof is obviously inferior to offsetof here, so
14579 stick with offsetof.
14580 (GC_POINTER_ALIGNMENT): New macro.
14581 (mark_memory): Omit 3rd (offset) arg; caller changed.
14582 Don't assume EMACS_INT alignment is the same as pointer alignment.
14584 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14586 * keyboard.c (read_key_sequence_remapped): New var.
14587 (read_key_sequence): Compute remapping in the right buffer.
14588 (command_loop_1): Use read_key_sequence's remapping directly.
14590 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14592 * dired.c (file_name_completion): Don't expand file name.
14593 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14594 before checking file name handler.
14596 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14597 they've been requested explicitly (bug#9591).
14599 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14601 * keymap.c (Fsingle_key_description): Use make_specified_string
14602 instead of build_string to build string from push_key_description.
14605 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14607 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14608 This fixes a Y2038 bug on 64-bit hosts.
14609 * buffer.c (reset_buffer):
14610 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14611 (Fclear_buffer_auto_save_failure):
14612 Use 0, not -1, to represent an unset failure time, since time_t
14613 might not be signed.
14615 Remove dependency on glibc malloc internals.
14616 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14617 Move back here from lisp.h, but with their new implementations.
14618 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14619 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14620 * charset.c (charset_table_init): New static var.
14621 (syms_of_charset): Use it instead of xmalloc. This removes a
14622 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14623 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14624 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14625 Move back to alloc.c.
14626 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14627 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14629 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14631 * nsterm.m (windowDidResize): Call x_set_window_size only when
14632 ns_in_resize is true. Otherwise set pixelwidth/height and
14633 call change_frame_size (Bug#9628).
14635 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14637 Port --enable-checking=all to Fedora 14 x86-64.
14638 * charset.c (syms_of_charset): Also account for glibc malloc's
14639 internal overhead when calculating the initial malloc maximum.
14641 Port --enable-checking=all to Fedora 14 x86.
14642 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14644 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14645 (overrun_check_realloc, overrun_check_free):
14646 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14647 That way, xmalloc returns a properly-aligned pointer even if
14648 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14649 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14650 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14651 into account when calculating the initial malloc maximum.
14652 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14653 Move here from alloc.c, so that charset.c can use it too.
14654 Properly align; the old code wasn't right for common 32-bit hosts
14655 when configured with --enable-checking=all.
14656 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14657 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14659 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14661 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14664 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14666 * xdisp.c (compute_display_string_end): If there's no display
14667 string at CHARPOS, return -1.
14669 * bidi.c (bidi_fetch_char): When compute_display_string_end
14670 returns a negative value, treat the character as a normal
14671 character not covered by a display string. (Bug#9624)
14673 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14675 * lread.c (Fread_from_string): Fix typo in docstring.
14677 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14679 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14680 newline, reseat the iterator instead of bidi-iterating there one
14681 character at a time. (Bug#9610)
14682 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14683 TO_CHARPOS if the bidi iterator is at base embedding level.

14690 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14692 * dbusbind.c (Fdbus_register_signal): When service is not
14693 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14695 2011-09-25 Glenn Morris <rgm@gnu.org>
14697 * buffer.c (truncate-lines): Doc fix.
14699 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14701 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14702 (Fset_window_next_buffers): Doc fix.

14714 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14716 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14717 Default value is now t. Doc fix.
14719 * indent.c (Fvertical_motion): Compute and apply the overshoot
14720 logic when moving up, not only when moving down. Fix the
14721 confusing name and values of the it_overshoot_expected variable;
14722 logic changes accordingly. (Bug#9254) (Bug#9549)
14724 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14725 CHARPOS is covered by a display string which includes newlines.
14726 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14727 is covered by a display string with embedded newlines.
14729 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14731 * dbusbind.c (Fdbus_register_signal): Add match rule to
14732 Vdbus_registered_objects_table. (Bug#9581)
14733 (Fdbus_register_method, Vdbus_registered_objects_table):
14736 2011-09-24 Jim Meyering <meyering@redhat.com>
14738 do not ignore write error for any output size
14739 The previous change was incomplete.
14740 While it makes emacs --batch detect the vast majority of stdout
14741 write failures, errors were still ignored whenever the output size is
14742 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14743 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14744 && echo FAIL: ignored write error
14745 FAIL: ignored write error
14746 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14747 && echo FAIL: ignored write error
14748 FAIL: ignored write error
14749 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14751 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14753 * emacs.c (Fkill_emacs): In noninteractive mode exit
14754 non-successfully if a write error occurred on stdout. (Bug#9574)
14756 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14758 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass

14764 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14766 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14767 a display string, extend search for cursor position to end of row.
14768 (find_row_edges): If the row ends in a newline from a display
14769 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14770 Handle the case of a display string with multiple newlines.
14771 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14772 non-empty line. Fixes confusing cursor motion with arrow keys at
14773 the beginning of a line that starts with whitespace.

14777 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14780 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14782 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14783 boolean (Bug#9154).
14785 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14787 * xdisp.c (display_line): Record maximum and minimum buffer
14788 positions even if no glyphs were produced (e.g., by a zero-width
14789 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14790 buffer positions that will be removed from the glyph row because
14792 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14793 column is beyond frame width: don't subtract 1 "pixel" when
14794 computing width of the stretch.
14795 (reseat_at_next_visible_line_start): Undo the change made on
14796 2011-09-17 that saved paragraph information and restored it after
14797 the call to `reseat'. (Bug#9545)
14799 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14801 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14802 and turn window cursor on if cleared (Bug#9415).
14804 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14806 * search.c (boyer_moore): Take unibyte characters from pattern
14807 literally. (Bug#9458)

14820 (Finsert_file_contents): Save and restore errno,
14821 so that report_file_error outputs the correct diagnostic.

14828 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14830 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

14833 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14835 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14836 about the current paragraph and restore it after the call to reseat.
14838 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14839 (bidi_find_paragraph_start): Search back for paragraph beginning
14840 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14841 (bidi_move_to_visually_next): Only trigger paragraph-related
14842 computations when the last character is a newline or at EOB, not
14843 just any NEUTRAL_B. (Bug#9470)
14845 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14846 truncated lines if point is covered by a display string. (Bug#9524)
14848 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14850 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14851 (cons_to_x_long): New function.
14852 (lisp_data_to_selection_data): Use it. Correct the test for
14853 short-versus-long data; it was negated. Break out of vector
14854 loop, for efficiency, when a long datum is discovered.
14856 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14858 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

14887 This occurs when processing a multibyte format.
14888 Problem reported by Wolfgang Jenker.
14890 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14892 * xdisp.c (try_cursor_movement): Only check for exact match if
14893 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14895 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14897 Remove unused external symbols.
14898 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14899 * xdisp.c (calc_pixel_width_or_height): Now static.
14900 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

14905 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14907 * xselect.c: Use signed conversions more consistently (Bug#9498).
14908 (selection_data_to_lisp_data): Assume incoming selection data are
14909 signed integers, not unsigned. This is to be consistent with
14910 outgoing selection data, which was modified to use signed integers
14911 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14912 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14913 expects long, not unsigned long.
14915 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14917 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14918 computation of loop end. Reported by Johan Bockgård
14921 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14923 * frame.c (Fother_visible_frames_p): Function deleted.
14925 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14927 * indent.c (compute_motion): Process display vector front to back
14928 rather than the other way around. (Bug#2496)
14930 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14932 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14934 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14936 * minibuf.c (Fread_from_minibuffer): Doc fix.
14938 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14940 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14941 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14943 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14945 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14946 value for non-existent files.
14948 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14950 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14951 set its "size" to -1. This will set the modtime_size field of
14952 the corresponding buffer to -1, which is what
14953 verify-visited-file-modtime expects for files that do not exist.
14956 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14958 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14960 * lisp.h: ... from here. push_key_description is no longer
14961 defined in keyboard.c, so its declaration should not be in
14962 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14963 logically belongs with push_key_description.
14965 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14967 * buffer.h: Include <sys/types.h> instead of <time.h>.
14968 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14969 Problem reported by Herbert J. Skuhra.
14971 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14973 * xml.c (parse_region): Make the parsing work for
14974 non-comment-starting XML files again (bug#9144).
14976 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14978 * image.c (gif_load): Fix calculation of bottom and right corner.
14981 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14983 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14984 redisplay in small windows.
14986 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14988 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14990 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14992 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14993 Operate on live windows only.
14995 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14997 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14999 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15001 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15002 only under bidi iteration.
15004 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15006 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15008 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15010 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15011 Without this fix, the command to link temacs failed due to an
15012 undefined symbol __builtin_isnan. This is because
15013 /usr/include/iso/math_c99.h #defines isnan(x) to
15014 __builtin_isnan(x), but the bundled gcc, which identifies itself
15015 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15017 * floatfns.c (isnan): #undef, and then #define to a clone of
15019 (Fisnan): Always define, since it's always available now.
15020 (syms_of_floatfns): Always define isnan at the Lisp level.
15022 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15024 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15026 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15028 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15029 The previous code assumed that file offsets (off_t values) fit in
15030 EMACS_INT variables, which is not true on typical 32-bit hosts.
15031 The code messed up by falsely reporting buffer overflow in cases
15032 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15033 when "big" contains more than 2**29 bytes, even though this
15034 inserts just one byte and does not overflow the buffer.
15035 (Finsert_file_contents): Store file offsets as off_t
15036 values, not as EMACS_INT values. Check for overflow when
15037 converting between EMACS_INT and off_t. When checking for
15038 buffer overflow or for overlap, take the offsets into account.
15039 Don't use EMACS_INT for small values where int suffices.
15040 When checking for overlap, fix a typo: ZV was used where
15041 ZV_BYTE was intended.
15042 (Fwrite_region): Don't assume off_t fits into 'long'.
15043 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15045 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15047 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15049 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15051 sprintf-related integer and memory overflow issues (Bug#9412).
15053 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15054 (esprintf, exprintf, evxprintf): New functions.
15055 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15056 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15057 (modify_event_symbol): Do not assume that the length of
15058 name_alist_or_stem is safe to alloca and fits in int.
15059 (Fexecute_extended_command): Likewise for function name and binding.
15060 (Frecursion_depth): Wrap around reliably on integer overflow.
15061 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15062 since some callers pass EMACS_INT values.
15063 (Fsingle_key_description): Don't crash if symbol name contains more
15064 than MAX_ALLOCA bytes.
15065 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15066 (get_minibuffer): Arg is now EMACS_INT, not int.
15067 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15068 (esprintf, exprintf, evxprintf): New decls.
15069 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15071 * dbusbind.c (signature_cat): New function.
15072 (xd_signature, Fdbus_register_signal):
15073 Do not overrun buffer; instead, report string overflow.
15075 * dispnew.c (add_window_display_history): Don't overrun buffer.
15076 Truncate instead; this is OK since it's just a log.
15078 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15079 even if the time zone offset is outlandishly large.
15080 Don't mishandle offset == INT_MIN.
15082 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15083 when creating daemon; the previous buffer-overflow check was incorrect.
15085 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15086 which has the guts of the old verror function.
15088 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15089 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15091 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15092 (font_unparse_xlfd): Don't blindly alloca long strings.
15093 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15094 fits in int, when using sprintf. Use single snprintf to count
15095 length of string rather than counting it via multiple sprintfs;
15096 that's simpler and more reliable.
15097 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15098 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15099 sprintf, in case result does not fit in int.
15101 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15102 (fontset_from_font): Print it.
15104 * frame.c (tty_frame_count): Now printmax_t, not int.
15105 (make_terminal_frame, set_term_frame_name): Print it.
15106 (x_report_frame_params): In X, window IDs are unsigned long,
15107 not signed long, so print them as unsigned.
15108 (validate_x_resource_name): Check for implausibly long names,
15109 and don't assume name length fits in 'int'.
15110 (x_get_resource_string): Don't blindly alloca invocation name;
15111 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15114 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15115 (xg_check_special_colors, xg_set_geometry):
15116 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15118 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15119 Use esprintf, not sprintf, in case result does not fit in int.
15121 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15122 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15123 it as a large positive number.
15124 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15125 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15127 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15128 in case result does not fit in int.
15130 * print.c (float_to_string): Detect width overflow more reliably.
15131 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15132 buffer overrun. Don't assume list length fits in 'int'. Treat
15133 print length of 0 as 0, not as infinity; to be consistent with other
15134 uses of print length in this function. Don't overflow print length
15135 index. Don't assume hash table size fits in 'long', or that
15136 vectorlike size fits in 'unsigned long'.
15138 * process.c (make_process): Use printmax_t, not int, to format
15139 process-name gensyms.
15141 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15143 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15144 to avoid potential buffer overrun.
15146 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15147 if X resource line is longer than 512 bytes.
15149 * xfns.c (x_window): Make sprintf buffer a bit bigger
15150 to avoid potential buffer overrun.
15152 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15154 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15156 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15158 Integer overflow fixes for scrolling, etc.
15159 Without these, Emacs silently mishandles large integers sometimes.
15160 For example, "C-u 4294967297 M-x recenter" was treated as if
15161 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15163 * xdisp.c (try_window_id): Check Emacs fixnum range before
15164 converting to 'int'.
15166 * window.c (window_scroll_line_based, Frecenter):
15167 Check that an Emacs fixnum is in range before assigning it to 'int'.
15168 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15169 values converted from Emacs fixnums.
15170 (Frecenter): Don't wrap around a line count if it is out of 'int'
15171 range; instead, treat it as an extreme value.
15172 (Fset_window_configuration, compare_window_configurations):
15173 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15175 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15176 that can exceed INT_MAX. Check that EMACS_INT value is in range
15177 before assigning it to the (possibly-narrower) index.
15178 (match_limit): Don't assume that a fixnum can fit in 'int'.
15180 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15183 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15184 (Fvertical_motion): Don't wrap around LINES values that don't fit
15185 in 'int'. Instead, treat them as extreme values. This is good
15186 enough for windows, which can't have more than INT_MAX lines anyway.
15188 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15190 * Require libxml/parser.h to avoid compilation warning.
15192 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15194 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15195 since this reportedly can destroy thread storage.
15197 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15199 * syntax.c (find_defun_start): Update all cache variables if
15200 exiting early (Bug#9401).
15202 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15204 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15206 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15207 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15208 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15210 * term.c (tty_append_glyph): New function.
15211 (produce_stretch_glyph): Static function and its prototype deleted.
15213 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15216 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15218 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15219 when checking :margin (Bug#9390).
15220 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15221 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15222 so that the name doesn't mislead. All uses changed.
15224 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15226 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15229 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15231 * xdisp.c (move_it_to): Don't bail out early when reaching
15232 position beyond to_charpos, if we are scanning backwards.
15233 (move_it_vertically_backward): When DY == 0, make sure we get to
15234 the first character in the line after the newline.
15236 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15238 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15239 (ccl_driver): Do not generate an out-of-range pointer.
15240 (Fccl_execute_on_string): Remove unnecessary check for
15241 integer overflow, noted by Stefan Monnier in
15242 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15243 Remove a FIXME that didn't need fixing.
15244 Simplify the newly-introduced buffer reallocation code.
15246 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15248 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15250 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15252 Integer and memory overflow issues (Bug#9196).
15254 * doc.c (get_doc_string): Rework so that
15255 get_doc_string_buffer_size is the actual buffer size, rather than
15256 being 1 less than the actual buffer size; this makes xpalloc more
15259 * image.c (x_allocate_bitmap_record, cache_image):
15260 * xselect.c (Fx_register_dnd_atom):
15261 Simplify previous changes by using xpalloc.
15263 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15264 since either will do and ptrdiff_t is convenient with xpalloc.
15266 * charset.c (charset_table_size)
15267 (struct charset_sort_data.priority): Now ptrdiff_t.
15268 (charset_compare): Don't overflow if priorities differ greatly.
15269 (Fsort_charsets): Don't assume list length fits in int.
15270 Check for size-calculation overflow when allocating sort data.
15271 (syms_of_charset): Allocate an initial charset table that is
15272 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15274 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15276 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15277 The actual value is always <= INT_MAX, and leaving it unsigned made
15278 overflow checking harder.
15280 * dispextern.h (struct glyph_matrix.rows_allocated)
15281 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15282 with xpalloc. The values are still always <= INT_MAX.
15284 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15286 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15287 (SAFE_NALLOCA): New macro.
15289 * region-cache.c (struct boundary.pos, find_cache_boundary)
15290 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15291 (set_cache_region, invalidate_region_cache)
15292 (revalidate_region_cache, know_region_cache, region_cache_forward)
15293 (region_cache_backward, pp_cache):
15294 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15295 so that ptrdiff_t * can be passed to xpalloc.
15296 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15297 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15298 (pp_cache): Don't assume cache_len fits in int.
15299 * region-cache.h: Adjust extern decls to match.
15301 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15302 EMACS_INT, since either will do, for xpalloc.
15304 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15305 (xnmalloc, xnrealloc, xpalloc): New functions.
15307 * bidi.c (bidi_shelve_header_size): New constant.
15308 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15309 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15311 * bidi.c (bidi_cache_shrink):
15312 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15314 Don't update size of array until after memory allocation succeeds,
15315 because xmalloc/xrealloc may not return.
15316 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15317 now that we have proper integer overflow checking.
15318 (record_overlay_string, overlay_strings): Catch overflows when
15319 calculating size of overlay_str_buf.
15321 * callproc.c (Fcall_process): Check for size overflow when
15322 calculating size of args2.
15323 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15324 Normally we prefer signed values, but sticking with ptrdiff_t would
15325 require adding more-complicated checks.
15327 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15328 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15329 Redo buffer-overflow calculations to avoid integer overflow.
15330 Add a FIXME comment where memory seems to be over-allocated.
15332 * character.c (Fstring): Check for size-calculation overflow.
15334 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15335 unnecessary integer overflow. Check for size overflow.
15336 (encode_coding_object): Don't update size until xmalloc succeeds.
15338 * composite.c (get_composition_id): Check for overflow in glyph
15339 length calculations.
15341 Integer and memory overflow fixes for display code.
15342 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15343 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15344 (scrolling_window): Check for overflow in size calculations.

15348 (row_table_size): Now ptrdiff_t, not int.
15349 (scrolling_window): Avoid overflow in size calculations.
15350 Don't update size until allocation succeeds.
15351 * fns.c (concat): Check for overflow in size calculations.
15352 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15353 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15356 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15357 (get_doc_string): Check for size calculation overflow.
15358 Don't update size until allocation succeeds.
15359 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15360 EMACS_INT, where ptrdiff_t will do.
15361 (Fsubstitute_command_keys): Check for string overflow.
15363 * editfns.c (set_time_zone_rule): Don't assume environment length
15365 (message_length): Now ptrdiff_t, not int.
15366 (Fmessage_box): Don't update size until allocation succeeds.
15367 Don't assume message length fits in int.
15368 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15370 * emacs.c (main): Do not reallocate argv, since there is a null at
15371 the end that can be overwritten, and this way there's no need to
15372 worry about size-calculation overflow.
15373 (sort_args): Check for size-calculation overflow.
15375 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15377 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15379 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15380 (x_set_scroll_bar_width, x_figure_window_size):
15381 Check for integer overflow.
15382 (x_set_alpha): Do not assume XINT fits in int.
15384 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15385 This is for the members text_lines, text_cols, total_lines, total_cols,
15386 where the system imposes an 'int' limit.
15388 * fringe.c (Fdefine_fringe_bitmap):
15389 Don't update size until alloc works.
15391 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15392 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15394 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15395 Check for size-calculation overflow.
15396 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15397 do, as we prefer signed integers.
15398 (id_to_widget.max_size, id_to_widget.used)
15399 (xg_store_widget_in_map, xg_remove_widget_from_map)
15400 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15401 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15402 Use and return ptrdiff_t, not int.
15403 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15404 * gtkutil.h: Change prototypes to match the above.
15406 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15407 are duplicate now that they've been promoted to lisp.h.
15408 (x_allocate_bitmap_record, x_alloc_image_color)
15409 (make_image_cache, cache_image, xpm_load):
15410 Don't update size until alloc is done.
15411 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15413 Check for size calculation overflow.
15414 (ct_colors_allocated_max): New constant.
15415 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

15420 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15421 Use ptrdiff_t, not int, to count maps.
15422 (read_char_minibuf_menu_prompt): Check for overflow in size
15423 calculations. Don't update size until allocation succeeds.
15424 Redo calculations to avoid overflow.
15425 * keyboard.h: Change prototypes to match the above.
15427 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15429 (current_minor_maps): Check for size calculation overflow.
15430 * keymap.h: Change prototypes to match the above.
15432 * lread.c (read1, init_obarray): Don't update size until alloc done.
15434 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15435 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15437 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15438 Now ptrdiff_t, not int.
15439 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15451 (Fset_match_data): Don't assume list lengths fit in 'int'.
15453 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15454 for command line length. Do not attempt to address one before the
15455 beginning of an array, as that's not portable.
15457 * term.c (max_frame_lines): Remove; unused.
15458 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15460 (encode_terminal_code, calculate_costs): Check for size
15461 calculation overflow.

15464 done. Redo calculations to avoid overflow.
15465 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15467 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15468 subtracting pointers.
15469 (gobble_line): Check for overflow more carefully. Don't update size
15472 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

15483 Use ptrdiff_t, not int, for sizes.
15484 (Finternal_make_lisp_face, cache_face):
15485 Check for size calculation overflow.
15486 (cache_face): Treat size calculation overflows as if they were
15487 memory exhaustion (the usual treatment), rather than aborting.
15489 * xfns.c (x_encode_text, x_set_name_internal)
15490 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15491 sizes, since they can exceed INT_MAX in size. Check for size
15492 calculation overflow.
15494 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15495 (xg_select): Check for size calculation overflow.
15496 Don't update size until alloc done.
15498 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15499 as sprintf is limited to int lengths.
15501 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15502 (X_LONG_MIN): New macros.
15503 Use them to make the following changes clearer.
15504 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15505 This change doesn't affect the value now, but it may help remind
15506 future maintainers not to raise the value too much later.
15507 (SELECTION_QUANTUM): Remove, replacing with ...
15508 (selection_quantum): ... new function, which avoids overflow.
15510 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15511 assumption that selection length fits in 'int'.
15512 (x_reply_selection_request, x_handle_selection_request)
15513 (x_get_window_property, receive_incremental_selection)
15514 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15515 (lisp_data_to_selection_data, clean_local_selection_data):

15517 (x_reply_selection_request, x_get_window_property)
15518 (receive_incremental_selection, x_property_data_to_lisp):
15519 Redo calculations to avoid overflow.
15520 (x_reply_selection_request): When sending hint, ceiling it at
15521 X_LONG_MAX rather than relying on wraparound overflow to send
15523 (x_get_window_property, receive_incremental_selection)
15524 (lisp_data_to_selection_data, x_property_data_to_lisp):
15525 Check for size-calculation overflow.
15526 (x_get_window_property, receive_incremental_selection)
15527 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15528 Don't store size until memory allocation succeeds.
15529 (x_get_window_property): Plug memory leak on memory exhaustion.
15530 Don't double-block input; malloc is safe here. Don't assume 2**34
15531 - 4 fits in unsigned long. Add an xassert to check
15532 XGetWindowProperty overflow. Be more careful about overflow
15533 calculations, and distinguish size from memory overflow better.
15534 (receive_incremental_selection): When tracing, don't assume
15535 unsigned int is less than INT_MAX.
15536 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15537 harmful) conversions of unsigned short to int.
15538 (lisp_data_to_selection_data): Don't assume that integers
15539 in the range -65535 through -1 fit in an X unsigned short.
15540 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15541 result parameters unless successful. Rely on cons_to_unsigned
15542 to report problems with elements; the old code wasn't right anyway.
15543 (x_check_property_data): Check for int overflow; we cannot use
15544 a wider type due to X limits.
15545 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15547 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15549 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)

15576 * image.c (xpm_get_color_table_h):
15577 * lisp.h (hash_lookup, hash_put):
15578 * minibuf.c (Ftest_completion):
15579 Use ptrdiff_t for hash table indexes, not int (which is too
15580 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15581 32-bit --with-wide-int hosts).
15583 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15584 Add a FIXME comment about memory leaks.
15585 (syms_of_charset): Don't assume xmalloc returns.
15587 Don't assume that stated character widths fit in int.
15588 * character.c (Fchar_width, c_string_width, lisp_string_width):
15589 * character.h (CHAR_WIDTH):
15590 * indent.c (MULTIBYTE_BYTES_WIDTH):
15591 Use sanitize_char_width to avoid undefined and/or bad behavior
15592 with outlandish widths.
15593 * character.h (sanitize_tab_width): Rename from sanitize_width,
15594 now that we have two such functions. All uses changed.
15595 (sanitize_char_width): New inline function.
15597 Don't assume that tab-width fits in int.
15598 * character.h (sanitize_width): New inline function.
15599 (SANE_TAB_WIDTH): New macro.
15600 (ASCII_CHAR_WIDTH): Use it.

15605 * fileio.c: Integer overflow issues with file modes.
15606 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15608 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
15609 Remove unreachable code.
15610 (read_hex, load_charset_map_from_file): Check for integer overflow.
15612 * xterm.c: Don't go over XClientMessageEvent limit.
15613 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15614 (x_send_scroll_bar_event): Likewise. Check that the size does not
15615 exceed limits imposed by XClientMessageEvent, as well as the usual
15616 ptrdiff_t and size_t limits.
15618 * keyboard.c: Overflow, signedness and related fixes.
15619 (make_lispy_movement): Use same integer type in forward decl
15620 that is used in the definition.
15621 (read_key_sequence, keyremap_step):
15622 Change bufsize argument back to int, undoing my 2011-03-30 change.
15623 We prefer signed types, and int is wide enough here.
15624 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15625 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15626 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15627 length, not size_t. Use ptrdiff_t for index, not int.
15628 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15629 possibility of integer overflow.
15631 Overflow, signedness and related fixes for images.
15633 * dispextern.h (struct it.stack[0].u.image.image_id)
15634 (struct_it.image_id, struct image.id, struct image_cache.size)

15641 * xdisp.c (calc_pixel_width_or_height):
15642 * xfns.c (image_cache_refcount):
15643 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
15644 on typical 64-bit hosts.

15650 when the callers expect that.
15651 (image_ascent): Redo ascent calculation to avoid int overflow.
15652 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
15653 (lookup_image): Remove unnecessary tests.
15654 (xbm_image_p): Locals are now of int, not EMACS_INT,
15655 since parse_image_check makes sure they fit into int.
15656 (png_load, gif_load, svg_load_image):
15657 Prefer int to unsigned where either will do.
15658 (tiff_handler): New function, combining the cores of the
15659 old tiff_error_handler and tiff_warning_handler.
15660 This function is rewritten to use vsnprintf and thereby avoid
15661 stack buffer overflows. It uses only the features of vsnprintf
15662 that are common to both POSIX and native Microsoft.
15663 (tiff_error_handler, tiff_warning_handler): Use it.
15664 (tiff_load, gif_load, imagemagick_load_image):
15665 Don't assume :index value fits in 'int'.
15666 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15667 (imagemagick_load_image): Check that crop parameters fit into
15668 the integer types that MagickCropImage accepts. Don't assume
15669 Vimagemagick_render_type has a nonnegative value. Don't assume
15670 size_t fits in 'long'.
15671 (gs_load): Use printmax_t to print the widest integers possible.
15672 Check for integer overflow when computing image height and width.

15682 the display spec is of the form `(space ...)'.
15683 (handle_display_spec): Return the value returned by
15684 handle_single_display_spec, not just 1 or zero.
15685 (handle_single_display_spec): If the display spec is of the form
15686 `(space ...)', and specifies display in the text area, return 2
15688 (try_cursor_movement): Check for the need to scroll more
15689 accurately, and prefer exact match for point under bidi.
15690 Don't advance `row' beyond the last row of the window.
15692 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15693 into disp_prop; all users changed.
15695 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
15696 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
15697 for the text covered by the display property.

15707 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15708 buffers, return left-to-right.
15709 (set_cursor_from_row): Consider candidate row a win if its glyph
15710 represents a newline and point is on that newline. Fixes cursor
15711 positioning on the newline at EOL of R2L text within L2R
15712 paragraph, and vice versa.
15713 (try_cursor_movement): Check continued rows, in addition to
15714 continuation rows. Fixes unwarranted scroll when point enters a
15715 continued line of R2L text within an L2R paragraph, or vice versa.
15716 (cursor_row_p): Consider the case of point being equal to
15717 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15718 from the end of a short line to the beginning of a continued line
15719 of R2L text within L2R paragraph.
15720 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
15721 composed characters.
15723 * bidi.c (bidi_check_type): Use xassert.
15724 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
15727 2011-08-23 Eli Zaretskii <eliz@gnu.org>

15734 * nsfont.m (ns_otf_to_script): Fix typo.
15736 2011-08-22 Kenichi Handa <handa@m17n.org>
15738 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15739 extra slot even if the purpose is char-code-property-table.
15741 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15743 * xdisp.c (redisplay_window): When computing centering_position,
15744 account for the height of the header line. (Bug#8874)
15746 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15747 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15748 candidate is selected by the mouse, and that candidate has a
15749 composed character under the mouse.
15751 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15752 coordinates reported by pos-visible-in-window-p for a composed
15753 character in column zero.
15755 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
15757 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
15759 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15761 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15762 consider it a hit if to_charpos is anywhere in the range of the
15763 composed buffer positions.
15765 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15767 * image.c (gif_load): Don't assume that each subimage has the same
15768 dimensions as the base image. Handle disposal method that is
15769 "undefined" by the gif spec (Bug#9335).
15771 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15773 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15774 (Fcondition_case): Document `debug' symbol in error handler.
15776 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15778 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15779 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15780 from an Org mode buffer to a Speedbar frame.
15782 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15783 a composition, take its buffer position from IT->cmp_it.charpos.
15784 Fixes cursor positioning at the beginning of a line that begins
15785 with a composed character.
15787 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15789 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15790 character bidirectional type, use STRONG_L instead. Fixes crashes
15791 in a buffer produced by `describe-categories'.
15793 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15794 members before the level stack, so they would be saved and
15795 restored when copying iterator state. Fixes incorrect reordering
15796 around TABs covered by display properties.
15798 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15800 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15806 Remove unnecessary aborts (Bug#9081).
15808 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15810 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15811 has no `load' handler, try opening the file locally. (Bug#9311)
15813 2011-08-16 Ken Brown <kbrown@cornell.edu>
15815 * gmalloc.c: Expand comment.
15817 2011-08-16 Eli Zaretskii <eliz@gnu.org>

15870 * xdisp.c (move_it_in_display_line_to): Don't invoke
15871 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15872 ppos_it. Fixes vertical cursor motion when line beginning is
15873 covered by an image. (Bug#9296)
15875 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15877 * nsterm.h (ns_run_ascript): Declare.

15881 (ns_run_ascript): New function.
15882 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15883 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15884 the event loop. Get status from as_status (Bug#7276).
15886 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15887 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15888 the event loop (Bug#7276).
15890 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

15914 (Fnetwork_interface_list): Allocate in increments of bytes instead
15915 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15916 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15918 (struct ifflag_def): notrailers is smart on OSX.
15919 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15920 Get hardware address with getifaddrs if available.
15922 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15924 * xdisp.c (iterate_out_of_display_property): xassert that
15925 IT->position is set to within IT->object's boundaries. Break from

15928 Set IT->current to match the bidi iterator unconditionally.
15929 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15930 entry. Force push_it to save on the stack the current
15931 buffer/string position, to be restored by pop_it. Fix flags in
15932 the iterator structure wrt the object coming from a display
15933 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15934 properties. (Bug#9284)
15936 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15938 * fontset.c (fontset_get_font_group): Add proper type checks.

15966 restore_point_unwind (Bug#5984).
15968 2011-08-07 Juri Linkov <juri@jurta.org>
15970 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

15973 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15975 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15976 display property strides EOL and includes a newline, as in
15977 longlines-mode. (Bug#9254)
15978 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15979 word-wrap under bidirectional display. (Bug#9224)
15981 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15982 is non-zero, even if the data buffer is NULL. Fixes a crash in
15983 vertical-motion with longlines-mode. (Bug#9254)
15985 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15987 * bidi.c <bidi_cache_total_alloc>: Now static.

15990 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15993 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15994 amount allocated this far in `bidi_cache_total_alloc'.
15995 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15996 non-zero, only free the data buffer without restoring the cache
15997 contents. All callers changed.
15999 * dispextern.h (bidi_unshelve_cache): Update prototype.
16001 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16002 (move_it_in_display_line, move_it_to)
16003 (move_it_vertically_backward, move_it_by_lines): Replace the call
16004 to xfree to an equivalent call to bidi_unshelve_cache.
16005 (move_it_in_display_line_to): Fix logic of returning
16006 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16008 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16010 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16011 came from a string character with a `cursor' property. (Bug#9229)

16032 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16034 * callproc.c (Fcall_process): Avoid vfork clobbering
16035 the local vars buffer, coding_systems, current_dir.
16037 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16039 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16041 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16043 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16044 so that it is not optimized away.
16046 * xdisp.c (compute_display_string_pos): Remove unused local.
16048 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16050 Fix slow cursor motion and scrolling in large buffers with
16051 selective display, like Org Mode buffers. (Bug#9218)
16053 * dispextern.h (struct bidi_it): New member disp_prop_p.
16055 * xdisp.c: Remove one-slot cache of display string positions.
16056 (compute_display_string_pos): Accept an additional argument
16057 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16058 for a display string or property. If found, set DISP_PROP_P
16061 * bidi.c (bidi_fetch_char): Accept an additional argument
16062 DISP_PROP_P, and pass it to compute_display_string_pos.
16063 Only handle text covered by a display string if DISP_PROP_P is returned
16064 non-zero. All callers of bidi_fetch_char changed.
16066 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16068 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16070 2010-12-03 Don March <don@ohspite.net>
16072 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16073 last character M-[char] is translated to ESC [char] (bug#7541).
16075 2011-08-02 Kenichi Handa <handa@m17n.org>
16077 * lisp.h (uniprop_table): Extern it.
16079 * chartab.c (uniprop_table): Make it non-static.
16081 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16083 * xdisp.c (forward_to_next_line_start): Accept additional argument
16084 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16086 (reseat_at_next_visible_line_start): Use the bidi iterator state
16087 returned by forward_to_next_line_start to restore the state of
16088 it->bidi_it after backing up to previous newline. (Bug#9212)
16090 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16092 * regex.c (re_comp): Protoize.
16093 (re_exec): Fix return type.
16094 (regexec): Fix type of `ret'. (Bug#9203)
16096 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16098 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16099 This is needed if max-image-size is a floating-point number.
16101 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16103 * print.c (print_object): Print empty symbol as ##.
16105 * lread.c (read1): Read ## as empty symbol.
16107 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16109 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16110 setting frame foreground color (Bug#9175).
16111 (x_set_background_color): Likewise.
16113 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16114 contents (Bug#9176).
16115 (EmacsTooltip -init): Remove bezels and add shadows to
16118 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16119 or scroll bar (Bug#8470).
16121 * nsfont.m (nsfont_open): Remove assignment to voffset and
16122 unnecessary vars hshink, expand, hd, full_height, min_height.
16123 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16125 * nsterm.h (nsfont_info): Remove voffset field.
16127 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16129 Implement strike-through and overline on NextStep (Bug#8863).
16131 * nsfont.m (nsfont_open): Use underline position provided by font,
16132 instead of hard-coded value of 2.
16133 (nsfont_draw): Call ns_draw_text_decoration instead.
16135 * nsterm.h: Add declaration for ns_draw_text_decoration.
16137 * nsterm.m (ns_draw_text_decoration): New function for drawing
16138 underline, overline, and strike-through.
16139 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16140 ns_draw_text_decoration. Change treatment of cursor drawing to
16141 accommodate underlining, etc.
16143 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16145 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16148 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16150 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16151 Without this fix, if a signal arrives just after memory fills up,
16152 'malloc' might be invoked reentrantly.
16154 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16155 In other words, assume that every image size is allowed, on non-X
16156 hosts. This assumption is probably wrong, but it lets Emacs compile.
16158 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16160 * regex.c (re_iswctype): Convert return values to boolean.
16162 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16164 * xdisp.c (compute_display_string_pos): Don't use cached display
16165 string position if the buffer had its restriction changed.
16168 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16170 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16172 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16174 Integer signedness and overflow and related fixes. (Bug#9079)
16176 * bidi.c: Integer size and overflow fixes.
16177 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16178 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16179 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16180 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16181 (bidi_find_other_level_edge):
16182 Use ptrdiff_t instead of EMACS_INT where either will do.
16183 This works better on 32-bit hosts configured --with-wide-int.
16184 (bidi_cache_ensure_space): Check for size-calculation overflow.
16185 Use % rather than repeated addition, for better worst-case speed.
16186 Don't set bidi_cache_size until after xrealloc returns, because it
16188 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16189 (bidi_cache_ensure_space): Also check that the bidi cache size
16190 does not exceed that of the largest Lisp string or buffer. See Eli
16191 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16193 * alloc.c (__malloc_size_t): Remove.
16194 All uses replaced by size_t. See Andreas Schwab's note
16195 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16197 * image.c: Improve checking for integer overflow.
16198 (check_image_size): Assume that f is nonnull, since
16199 it is always nonnull in practice. This is one less thing to
16200 worry about when checking for integer overflow later.
16201 (x_check_image_size): New function, which checks for integer
16202 overflow issues inside X.
16203 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16204 This removes the need for a memory_full check.
16205 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16206 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16207 (xbm_read_bitmap_data): Change locals back to 'int', since
16208 their values must fit in 'int'.
16209 (xpm_load_image, png_load, tiff_load):
16210 Invoke x_create_x_image_and_pixmap earlier,
16211 to avoid much needless work if the image is too large.
16212 (tiff_load): Treat overly large images as if
16213 x_create_x_image_and_pixmap failed, not as malloc failures.
16214 (gs_load): Use x_check_image_size.
16216 * gtkutil.c: Omit integer casts.
16217 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16218 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16220 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16222 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16223 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16224 would wrongly return t on a 64-bit host.
16226 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16227 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16228 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16229 and therefore cause GCC to emit a bogus diagnostic in some cases.
16231 * image.c: Integer signedness and overflow and related fixes.
16232 This is not an exhaustive set of fixes, but it's time to
16233 record what I've got.
16234 (lookup_pixel_color, check_image_size): Remove redundant decls.
16235 (check_image_size): Don't assume that arbitrary EMACS_INT values
16236 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16237 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16238 (tiff_load, imagemagick_load_image):
16239 Check for overflow in size calculations.
16240 (x_create_x_image_and_pixmap): Remove unnecessary test for
16241 xmalloc returning NULL; that can't happen.
16242 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16243 (xpm_color_bucket): Use better integer hashing function.
16244 (xpm_cache_color): Don't possibly over-allocate memory.
16245 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16246 (gif_memory_source):
16247 Use ptrdiff_t, not int or size_t, to record sizes.
16248 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16249 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16250 either works, as we prefer signed integers.
16251 (tiff_read_from_memory, tiff_write_from_memory):
16252 Return tsize_t, not size_t, since that's what the TIFF API wants.
16253 (tiff_read_from_memory): Don't fail simply because the read would
16254 go past EOF; instead, return a short read.
16255 (tiff_load): Omit no-longer-needed casts.
16256 (Fimagemagick_types): Don't assume size fits into 'int'.
16258 Improve hashing quality when configured --with-wide-int.
16259 * fns.c (hash_string): New function, taken from sxhash_string.
16260 Do not discard information about ASCII character case; this
16261 discarding is no longer needed.
16262 (sxhash-string): Use it. Change sig to match it. Caller changed.
16263 * lisp.h: Declare it.
16264 * lread.c (hash_string): Remove, since we now use fns.c's version.
16265 The fns.c version returns a wider integer if --with-wide-int is
16266 specified, so this should help the quality of the hashing a bit.
16268 * emacs.c: Integer overflow minor fix.
16269 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16270 Define only if GNU_LINUX.
16271 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16273 * dispnew.c: Integer signedness and overflow fixes.
16274 Remove unnecessary forward decls, that were a maintenance hassle.
16275 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16277 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16278 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16279 (prepare_desired_row, line_draw_cost):
16280 Use int, not unsigned, where either works.
16281 (save_current_matrix, restore_current_matrix):
16282 Use ptrdiff_t, not size_t, where either works.
16283 (init_display): Check for overflow more accurately, and without
16284 relying on undefined behavior.
16286 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16287 Remove, replacing with the new symbols in lisp.h. All uses changed.
16288 * fileio.c (make_temp_name):
16289 * filelock.c (lock_file_1, lock_file):
16290 * xdisp.c (message_dolog):
16291 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16292 Use pMd etc. instead.
16293 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16294 replacing the pWIDE etc. symbols removed from editfns.c.
16296 * keyboard.h (num_input_events): Now uintmax_t.
16297 This is (very slightly) less likely to mess up due to wraparound.
16300 * buffer.c: Integer signedness fixes.
16301 (alloc_buffer_text, enlarge_buffer_text):
16302 Use ptrdiff_t rather than size_t when either will do, as we prefer
16305 * alloc.c: Integer signedness and overflow fixes.
16306 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16307 (__malloc_size_t): Default to size_t, not to int.
16308 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16309 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16310 Prefer ptrdiff_t to size_t when either would do, as we prefer
16312 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16313 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16314 Now const. Initialize with values that are in range even if char
16316 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16317 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16318 These functions do the right thing with sizes > 2**32.
16319 (check_depth): Now ptrdiff_t, not int.
16320 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16321 Adjust to new way of storing sizes. Check for size overflow bugs
16323 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16324 slightly wrong anyway, as it missed one instance of
16325 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16326 (refill_memory_reserve): Omit needless cast to size_t.
16327 (mark_object_loop_halt): Mark as externally visible.
16329 * xselect.c: Integer signedness and overflow fixes.
16330 (Fx_register_dnd_atom, x_handle_dnd_message):
16331 Use ptrdiff_t, not size_t, since we prefer signed.
16332 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16333 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16334 x_dnd_atoms_size and x_dnd_atoms_length.
16336 * doprnt.c: Prefer signed to unsigned when either works.
16338 * doprnt.c (doprnt):
16340 * xdisp.c (vmessage):
16341 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16342 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16343 prefer signed arithmetic to avoid comparison confusion.
16344 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16345 but is a bit tricky.
16347 Assume freestanding C89 headers, string.h, stdlib.h.
16348 * data.c, doprnt.c, floatfns.c, print.c:
16349 Include float.h unconditionally.
16350 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16351 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16352 * regex.c: Likewise for stddef.h, string.h.
16353 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16354 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16355 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16356 (STDC_HEADERS): Remove obsolete defines.
16357 * sysdep.c: Include limits.h unconditionally.
16359 Assume support for memcmp, memcpy, memmove, memset.
16360 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16361 * regex.c (memcmp, memcpy):
16362 Remove; we assume C89 now.
16364 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16365 (__malloc_safe_bcopy): Remove; no longer needed.
16367 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16368 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16369 well either way, and we prefer signed to unsigned.
16371 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16373 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16374 closes the connection while we're reading (bug#9182).
16376 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16378 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16379 are specified (Bug#9168).
16381 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16383 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16384 Found by GCC static checking and --with-wide-int on a 32-bit host.
16386 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16388 * xdisp.c (compute_display_string_pos): Fix logic of caching
16389 previous display string position. Initialize cached_prev_pos to
16390 -1. Fixes slow-down at the beginning of a buffer.
16392 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16394 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16395 for attrs[LFACE_FONTSET_INDEX].
16397 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16399 * xml.c (parse_region): Remove unused local
16400 that was recently introduced.
16402 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16404 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16405 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16407 * xdisp.c (move_it_in_display_line_to): Record the best matching
16408 position for TO_CHARPOS while scanning the line, and restore it on
16409 exit if none of the characters scanned was an exact match.
16410 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16411 when exact match is impossible due to invisible text, and the
16412 lines are truncated.
16414 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16416 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16419 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16421 Fix a significant slow-down of cursor motion with C-n, C-p,
16422 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16423 auto-repeat under bidi redisplay in fontified buffers.
16424 * xdisp.c (compute_stop_pos_backwards): New function.
16425 (next_element_from_buffer): Call compute_stop_pos_backwards to
16426 find a suitable prev_stop when we find ourselves before
16428 (reseat): Don't look for prev_stop, as that could mean a very long
16430 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16431 <cached_disp_overlay_modiff>: Cache for last found display string
16433 (compute_display_string_pos): Return the cached position if asked
16434 about the same buffer in the same area of character positions, and
16435 the buffer wasn't changed since the time the display string
16436 position was cached.
16438 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16440 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16441 is an integer, which is important for empty lines. (Bug#9149)
16443 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16445 * frame.c (Fmodify_frame_parameters): In tty case, update the
16446 default face if necessary (Bug#4238).
16448 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16450 * editfns.c (Fstring_to_char): No need to explain what a character
16451 is in the docstring (Bug#6576).
16453 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16455 * xml.c (parse_region): Make sure we always return a tree.
16457 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16459 * xml.c (parse_region): If a document contains only comments,
16462 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16464 * xml.c (make_dom): Return comments, too.
16466 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16469 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16470 and the surrounding thread.
16471 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16472 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16473 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16475 * s/openbsd.h (BROKEN_SIGIO): Define.
16476 * unexelf.c (unexec) [__OpenBSD__]:
16477 Don't update the .mdebug section of the Alpha COFF symbol table.
16479 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16481 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16484 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16486 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16487 This fixes some race conditions on the permissions of any newly
16490 * alloc.c (valid_pointer_p): Use pipe, not open.
16491 This fixes some permissions issues when debugging.
16493 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16494 If fchown fails to set both uid and gid, try to set just gid,
16495 as that is sometimes allowed. Adjust the file's mode to eliminate
16496 setuid or setgid bits that are inappropriate if fchown fails.
16498 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16500 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16501 to compare Lisp_Objects.

16506 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16508 * lread.c (read_integer): Unread even EOF character.
16509 (read1): Likewise. Properly record start position of symbol.

16512 symbol character follows.
16514 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16516 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16517 This works around a problem with the previous change to Fcopy_file.
16518 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16519 and without this change, GCC might complain about discarding
16520 fchown's return value.
16522 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16524 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16526 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16528 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16530 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16532 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16533 it's used from the C level.
16535 * process.c: Use the same condition for POLL_FOR_INPUT in both
16536 keyboard.c and process.c (bug#1858).
16538 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16540 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16541 (Fgnutls_boot): Use it.
16543 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16545 * doc.c (Fsubstitute_command_keys): Revert last change.
16547 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16549 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16550 quotes the next character, and doesn't affect other longer
16551 sequences (bug#8935).
16553 * lread.c (syms_of_lread): Clarify that is isn't only
16554 `eval-buffer' and `eval-defun' that's affected by
16555 `lexical-binding' (bug#8460).
16557 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16559 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16560 bidi redisplay when a line includes both an image and is truncated.
16562 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16564 Fix minor problems found by static checking.
16565 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16566 (elsz): Now a signed constant, not a size_t var. We prefer signed
16567 types to unsigned, to avoid integer comparison confusion. Without
16568 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16569 "cannot optimize loop, the loop counter may overflow", a symptom
16571 * indent.c (Fvertical_motion): Mark locals as initialized.
16572 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16574 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16576 * search.c (Fre_search_backward): Mention `case-fold-search' in
16577 all the re_search_* functions (bug#8138).
16579 * keyboard.c (Fopen_dribble_file): Document when the file is

16600 (display_string): If we need to ignore text properties of
16601 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16602 original value of -1 will not work with bidi.)
16603 (compute_display_string_pos): First arg is now struct
16604 `text_pos *'; all callers changed. Support display properties on
16606 (compute_display_string_end): Support display properties on Lisp
16608 (init_iterator, reseat_1, reseat_to_string): Initialize the
16609 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16610 when iterating on a string not from display properties).
16611 (compute_display_string_pos, compute_display_string_end):
16612 Fix calculation of the object to scan. Fixes an error when using
16614 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16615 base_level_stop; instead, set base_level_stop to BEGV.
16616 Fixes crashes in vertical-motion.
16617 (next_element_from_buffer): Improve commentary for when
16618 the iterator is before prev_stop.
16619 (init_iterator): Initialize bidi_p from the default value of
16620 bidi-display-reordering, not from buffer-local value. Use the
16621 buffer-local value only if initializing for buffer iteration.
16622 (handle_invisible_prop): Support invisible properties on strings
16623 that are being bidi-reordered.

16630 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16631 (init_iterator): Don't initialize it->bidi_p for strings
16633 (reseat_to_string): Initialize it->bidi_p for strings here.

16641 (get_visually_first_element): New function, refactored from common
16642 parts of next_element_from_buffer, next_element_from_string, and
16643 next_element_from_c_string.
16644 (tool_bar_lines_needed, redisplay_tool_bar)
16645 (display_menu_bar): Force left-to-right direction. Add a FIXME
16646 comment for making that be controlled by a user option.

16655 (get_overlay_strings_1, push_display_prop): Set up the bidi
16656 iterator for displaying display or overlay strings.
16657 (forward_to_next_line_start): Don't use the shortcut if
16659 (back_to_previous_visible_line_start): If handle_display_prop
16660 pushed the iterator stack, restore the internal state of the bidi
16661 iterator by calling bidi_pop_it same number of times.
16662 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16663 and we are bidi-iterating, don't decrement the iterator position;
16664 instead, set the first_elt flag in the bidi iterator, to produce
16666 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16667 (push_display_prop): xassert that we are iterating a buffer.

16671 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16672 correctly. Don't assume unibyte strings are not bidi-reordered.

16681 property. Fix a typo in popping stretch info. Add an assertion
16682 for verifying that the iterator position is in sync with the bidi
16684 (handle_single_display_spec, get_overlay_strings_1)

16773 (bidi_push_it, bidi_pop_it): Add prototypes.
16774 (struct iterator_stack_entry): New members bidi_p,
16775 paragraph_embedding, and from_disp_prop_p.

17096 (clone_per_buffer_values): Don't assume that

17098 This isn't true in general, and it's particularly not true
17099 if Emacs is configured with --with-wide-int.
17100 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17101 New macros, used in the buffer.c change.

17137 Random fixes. E.g., (random) never returned negative values.
17138 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17139 subseconds part to the entropy, as that's a bit more random.
17140 Prefer signed to unsigned, since the signedness doesn't matter and
17141 in general we prefer signed. When given a limit, use a
17142 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17143 latter isn't right if USE_2_TAGS_FOR_INTS.
17144 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17145 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17157 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17158 This is more efficient than Ffile_directory_p and avoids a minor race.

17162 * buffer.c (Foverlay_put): Say what the return value is
17165 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17169 error be more correct.
17171 * fns.c (Frequire): Remove the mention of the .gz files, since
17172 that's installation-specific, but keep the mention of
17173 `get-load-suffixes'.

17188 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17189 Also (re)move comments that are misplaced or no longer relevant.

17218 * lread.c (syms_of_lread): Mention single symbols defined by

17290 * eval.c (struct backtrace): Simplify and port the data structure.
17291 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17292 signed bit field, as this assumption is not portable and it makes
17293 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17294 "char debug_on_exit : 1" as this is not portable either; instead,
17295 use the portable "unsigned int debug_on_exit : 1". Remove unused
17296 member evalargs. Remove obsolete comments about cc bombing out.
17298 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17365 (get_parent_class, emacs_fixed_set_min_size): Remove.
17366 (emacs_fixed_new): Set priv->f to argument.
17367 (emacs_fixed_get_preferred_width)
17368 (emacs_fixed_get_preferred_height): Use min_width/height from
17369 frames size_hint to set minimum and natural (Bug#8919).
17370 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17371 and use min_width/height from frames size_hint to set
17372 min_width/height (Bug#8919).
17374 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
17375 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.
17378 2011-06-26 Eli Zaretskii <eliz@gnu.org>
17380 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
17381 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
17384 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
17386 * process.c (wait_reading_process_output): Bypass select if
17387 waiting for a cell while ignoring keyboard input, and input is
17388 pending. Suggested by Jan Djärv (Bug#8869).
17390 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
17392 Use gnulib's dup2 module instead of rolling our own.
17393 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
17395 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17397 * dispnew.c (scrolling_window): Before scrolling, turn off a
17398 mouse-highlight in the window being scrolled.

17460 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17462 Integer and buffer overflow fixes (Bug#8873).
17464 * print.c (printchar, strout): Check for string overflow.
17465 (PRINTPREPARE, printchar, strout):
17466 Don't set size unless allocation succeeds.
17468 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17469 for sizes. Check for string overflow more accurately.
17470 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17472 * macros.c: Integer and buffer overflow fixes.
17473 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17474 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17475 Use ptrdiff_t, not int, for sizes.
17476 Don't increment bufsize until after realloc succeeds.
17477 Check for size-calculation overflow.
17478 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17480 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17482 * lread.c: Integer overflow fixes.
17483 (read_integer): Radix is now EMACS_INT, not int,
17484 to improve quality of diagnostics for out-of-range radices.
17485 Calculate buffer size correctly for out-of-range radices.
17486 (read1): Check for integer overflow in radices, and in
17487 read-circle numbers.
17488 (read_escape): Avoid int overflow.
17489 (Fload, openp, read_buffer_size, read1)
17490 (substitute_object_recurse, read_vector, read_list, map_obarray):
17491 Use ptrdiff_t, not int, for sizes.

17506 2011-06-22 Leo Liu <sdl.web@gmail.com>
17508 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17509 Move to minibuffer.el.
17511 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17513 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17514 The following patches are for when GLYPH_DEBUG && !XASSERT.
17515 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17516 * dispnew.c (flush_stdout):
17517 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17518 Mark as externally visible.
17519 * dispnew.c (check_window_matrix_pointers): Now static.
17520 * dispnew.c (window_to_frame_vpos):
17521 * xfns.c (unwind_create_frame):
17522 * xterm.c (x_check_font): Remove unused local.
17523 * scroll.c (CHECK_BOUNDS):
17524 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17525 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17526 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17527 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17528 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17530 (debug_method_add): Use va_list and vsprintf rather than relying
17531 on undefined behavior with wrong number of arguments.
17532 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17533 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17534 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17535 since we're not interested in debugging glyphs with old libraries.
17536 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17537 GCC 4.6.0's static checking.
17539 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17541 Integer overflow and signedness fixes (Bug#8873).

17552 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17553 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17555 * xfaces.c (load_pixmap):

17557 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17558 (.bitmaps_last, struct x_output.icon_bitmap):
17559 Use ptrdiff_t, not int, for bitmap indexes.
17560 (x_allocate_bitmap_record): Check for size overflow.
17561 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17563 Use ptrdiff_t, not int, for overlay counts.
17564 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17565 * editfns.c (overlays_around, get_pos_property):
17566 * textprop.c (get_char_property_and_overlay):
17567 * xdisp.c (next_overlay_change, note_mouse_highlight):
17568 * xfaces.c (face_at_buffer_position):
17569 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17570 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17571 (Fnext_overlay_change, Fprevious_overlay_change)
17572 (mouse_face_overlay_overlaps, Foverlays_in):
17573 Use ptrdiff_t, not int, for sizes.
17574 (overlays_at, overlays_in): Check for size-calculation overflow.
17576 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17578 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17579 (x_session_initialize): Do not assume string length fits in int.
17581 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17582 This is unlikely, but can occur if DPI is outlandish.
17584 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17585 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17587 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17588 * xrdb.c (magic_file_p, search_magic_path):
17589 Omit last arg SUFFIX; it was always 0. All callers changed.
17590 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17592 * xfont.c (xfont_match): Avoid need for strlen.
17594 * xfns.c: Don't assume strlen fits in int.
17595 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17597 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17598 not unsigned long, as we prefer signed integers. All callers changed.
17599 Detect integer overflow in repeat count.
17600 (message_dolog): Don't assume print length fits in 39 bytes.
17601 (display_mode_element): Don't assume strlen fits in int.
17603 * termcap.c: Don't assume sizes fit in int and never overflow.
17604 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17605 (gobble_line): Check for size-calculation overflow.
17607 * minibuf.c (Fread_buffer):
17608 * lread.c (intern, intern_c_string):

17613 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17615 * font.c: Don't assume string length fits in int.
17616 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17617 Use ptrdiff_t, not int.
17618 (font_intern_prop): Don't assume string length fits in int.
17619 Don't assume integer property fits in fixnum.
17620 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17622 * filelock.c: Fix some buffer overrun and integer overflow issues.
17623 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17624 Reformulate so as not to need the command string.
17625 Invoke gzip -cd rather than gunzip, as it's more portable.
17626 (lock_info_type, lock_file_1, lock_file):
17627 Don't assume pid_t and time_t fit in unsigned long.
17628 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17629 (current_lock_owner): Prefer signed type for sizes.
17630 Use memcpy, not strncpy, where memcpy is what is really wanted.
17631 Don't assume (via atoi) that time_t and pid_t fit in int.
17632 Check for time_t and/or pid_t out of range, e.g., via a network share.
17633 Don't alloca where an auto var works fine.
17635 * fileio.c: Fix some integer overflow issues.
17636 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17637 Don't assume string length fits in int.
17638 (directory_file_name): Don't assume string length fits in long.
17639 (make_temp_name): Don't assume pid fits in int, or that its print
17640 length is less than 20.
17642 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17644 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17646 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17648 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17649 We prefer signed integers, even for size calculations.
17651 * emacs.c: Don't assume string length fits in 'int'.
17652 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17653 (main): Don't invoke strlen when not needed.

17659 (Fgetenv_internal):
17660 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17662 * lread.c (invalid_syntax): Omit length argument.
17663 All uses changed. This doesn't fix a bug, but it simplifies the
17664 code away from its former Hollerith-constant appearance, and it's
17665 one less 'int' to worry about when looking at integer-overflow issues.
17666 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17668 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17669 This didn't break anything, but it didn't help either.
17670 It's confusing to put a bogus integer in a place where the actual
17671 value does not matter.
17672 (LIST_END_P): Remove unused macro and its bogus comment.
17673 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17675 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17676 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17678 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17679 We prefer signed types, and the value cannot exceed the EMACS_INT
17680 range anyway (because otherwise the length would not be representable).
17681 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17682 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17683 This avoids a GCC warning when WIDE_EMACS_INT.
17685 * indent.c (sane_tab_width): New function.
17686 (current_column, scan_for_column, Findent_to, position_indentation)
17687 (compute_motion): Use it. This is just for clarity.
17688 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17690 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

17693 * composite.c (composition_gstring_put_cache):
17694 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17696 * editfns.c, insdel.c:
17697 Omit unnecessary forward decls, to simplify future changes.
17699 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17701 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17703 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17704 Use much-faster test for byte-length change.
17705 Don't assume string byte-length fits in 'int'.
17706 Check that character arg fits in 'int'.
17707 (mapcar1): Declare byte as byte, for clarity.
17709 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17711 * fns.c (concat): Catch string overflow earlier.
17712 Do not rely on integer wraparound.
17714 * dispextern.h (struct it.overlay_strings_charpos)
17715 (struct it.selective): Now EMACS_INT, not int.
17716 * xdisp.c (forward_to_next_line_start)
17717 (back_to_previous_visible_line_start)
17718 (reseat_at_next_visible_line_start, next_element_from_buffer):
17719 Don't arbitrarily truncate the value of 'selective' to int.
17721 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17723 * composite.c: Don't truncate sizes to 'int'.
17724 (composition_gstring_p, composition_reseat_it)
17725 (composition_adjust_point): Use EMACS_INT, not int.
17726 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17727 not EMACS_UINT, for indexes.
17729 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17731 * buffer.c: Include <verify.h>.
17732 (struct sortvec.priority, struct sortstr.priority):
17733 Now EMACS_INT, not int.
17734 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17735 (struct sortstr.size, record_overlay_string)
17736 (struct sortstrlist.size, struct sortlist.used):
17737 Don't truncate size to int.
17738 (record_overlay_string): Check for size-calculation overflow.
17739 (init_buffer_once): Check at compile-time, not run-time.
17741 2011-06-22 Jim Meyering <meyering@redhat.com>
17743 Don't leak an XBM-image-sized buffer
17744 * image.c (xbm_load): Free the image buffer after using it.
17746 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17749 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17750 that Sun C diagnosed.
17751 * fns.c (secure_hash): Fix pointer signedness issue.
17752 * intervals.c (static_offset_intervals): New function.
17753 (offset_intervals): Use it.
17755 2011-06-21 Leo Liu <sdl.web@gmail.com>
17758 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17761 * fns.c (secure_hash): Rename from crypto_hash_function and change
17762 the first arg to accept symbols.
17763 (Fsecure_hash): New primitive.
17764 (syms_of_fns): New symbols.
17766 2011-06-20 Deniz Dogan <deniz@dogan.se>
17768 * process.c (Fset_process_buffer): Clarify return value in
17771 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17773 * dispnew.c (add_window_display_history): Use BVAR.
17775 * xdisp.c (debug_method_add): Use BVAR.
17776 (check_window_end, dump_glyph_matrix, dump_glyph)
17777 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17779 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17782 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17783 check till after the cache is created in init_frame_faces.
17785 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17787 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17789 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17791 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17792 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17793 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17795 Improve buffer-overflow checking (Bug#8873).
17796 * fileio.c (Finsert_file_contents):
17797 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17798 Remove the old (too-loose) buffer overflow checks.
17799 They weren't needed, since make_gap checks for buffer overflow.
17800 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17801 The old code merely checked for Emacs fixnum overflow, and relied
17802 on undefined (wraparound) behavior. The new code avoids undefined
17803 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17805 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17806 Tune. Don't use wider integers than needed. Don't use alloca.
17807 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17809 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17811 * insdel.c, lisp.h (buffer_overflow): New function.
17812 (insert_from_buffer_1, replace_range, replace_range_2):
17813 * insdel.c (make_gap_larger):
17814 * editfns.c (Finsert_char):
17815 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17817 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17819 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17821 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17823 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17824 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17826 * fileio.c: Don't assume EMACS_INT fits in off_t.
17827 (emacs_lseek): New static function.
17828 (Finsert_file_contents, Fwrite_region): Use it.
17829 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17831 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17833 * fns.c: Don't overflow int when computing a list length.
17834 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17835 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17836 truncation on 64-bit hosts. Check for QUIT every
17837 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17838 faster and is responsive enough.
17839 (Flength): Report an error instead of overflowing an integer.
17840 (Fsafe_length): Return a float if the value is not representable
17841 as a fixnum. This shouldn't happen except in contrived situations.
17842 (Fnthcdr, Fsort): Don't assume list length fits in int.
17843 (Fcopy_sequence): Don't assume vector length fits in int.
17845 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17846 (header_size, word_size): New constants.
17847 (allocate_vectorlike): Don't check size overflow here.
17848 (allocate_vector): Check it here instead, since this is the only
17849 caller of allocate_vectorlike that could cause overflow.
17850 Check that the new vector's length is representable as a fixnum.
17852 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17853 The previous code was bogus. For example, next_almost_prime (32)
17854 returned 39, which is undesirable as it is a multiple of 3; and
17855 next_almost_prime (24) returned 25, which is a multiple of 5 so
17856 why was the code bothering to check for multiples of 7?
17858 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17860 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17862 Variadic C functions now count arguments with ptrdiff_t.
17863 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17864 Back then I didn't know that the Emacs coding style prefers signed int.
17865 Also, in the meantime I found a few more instances where arguments
17866 were being counted with int, which may truncate counts on 64-bit
17867 machines, or EMACS_INT, which may be unnecessarily wide.
17868 * lisp.h (struct Lisp_Subr.function.aMANY)
17869 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17870 Arg counts are now ptrdiff_t, not size_t.
17871 All variadic functions and their callers changed accordingly.
17872 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17873 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17874 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17875 * callint.c (Fcall_interactively): Check arg count for overflow,
17876 to avoid potential buffer overrun. Use signed char, not 'int',
17877 for 'varies' array, so that we needn't bother to check its size
17878 calculation for overflow.
17879 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17880 * eval.c (apply_lambda):
17881 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17882 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17883 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17885 * callint.c (Fcall_interactively): Don't use index var as event count.
17887 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17888 * mem-limits.h (SIZE): Remove; no longer used.
17890 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17892 Remove unnecessary casts.
17893 * xterm.c (x_term_init):
17894 * xfns.c (x_set_border_pixel):
17895 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17896 These aren't needed now that we assume ANSI C.
17898 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17899 It's more likely to cause problems (due to unsigned overflow)
17902 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17904 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17906 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17908 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17910 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17912 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17914 GLYPH_CODE_FACE returns EMACS_INT, not int.
17915 * dispextern.h (merge_faces):
17916 * xfaces.c (merge_faces):
17917 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17918 Don't assume EMACS_INT fits in int.
17920 * character.h (CHAR_VALID_P): Remove unused parameter.
17921 * fontset.c, lisp.h, xdisp.c: All uses changed.
17923 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17925 * fns.c (concat): Minor tuning based on overflow analysis.
17926 This doesn't fix any bugs. Use int to hold character, instead
17927 of constantly refetching from Emacs object. Use XFASTINT, not
17928 XINT, for value known to be a character. Don't bother comparing
17929 a single byte to 0400, as it's always less.
17931 * floatfns.c (Fexpt):
17932 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17934 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17937 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17939 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17940 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17941 incorrectly succeed when S was a string, because 4294967386 was
17942 truncated before it was used.
17944 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17945 Otherwise, an out-of-range integer could cause undefined behavior
17948 * composite.c: Use int, not EMACS_INT, for characters.
17949 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17950 EMACS_INT, for values that are known to be in character range.
17951 This doesn't fix any bugs but is the usual style inside Emacs and
17952 may generate better code on 32-bit machines.
17954 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17955 This is for reasons similar to the recent CHAR_STRING fix.
17956 * charset.c (Fencode_char): Check that character arg is actually
17957 a character. Pass an int to ENCODE_CHAR.
17958 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17959 wider than 'int', as a compile-time check to prevent future regressions
17962 * character.c (char_string): Remove unnecessary casts.
17964 Make sure a 64-bit char is never passed to CHAR_STRING.
17965 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17966 by silently ignoring the top 32 bits, allowing some values
17967 that were far too large to be valid characters.
17968 * character.h: Include <verify.h>.
17969 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17970 arguments are no wider than unsigned, as a compile-time check
17971 to prevent future regressions in this area.
17973 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17974 (Fsubst_char_in_region):
17976 * xdisp.c (decode_mode_spec_coding):
17977 Adjust to CHAR_STRING's new requirement.
17978 * editfns.c (Finsert_char, Fsubst_char_in_region):
17979 * fns.c (concat): Check that character args are actually
17980 characters. Without this test, these functions did the wrong
17981 thing with wildly out-of-range values on 64-bit hosts.
17983 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17984 These casts should not be needed on 32-bit hosts, either.
17985 * keyboard.c (read_char):
17986 * lread.c (Fload): Remove casts to unsigned.
17988 * lisp.h (UNSIGNED_CMP): New macro.
17989 This fixes comparison bugs on 64-bit hosts.
17990 (ASCII_CHAR_P): Use it.
17991 * casefiddle.c (casify_object):
17992 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17993 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17994 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17995 * dispextern.h (FACE_FROM_ID):
17996 * keyboard.c (read_char): Use UNSIGNED_CMP.
17998 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17999 not to EMACS_INT, to avoid GCC warning.
18001 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18003 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18004 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18005 isn't needed on 32-bit machines.
18007 * buffer.c (Fgenerate_new_buffer_name):
18008 Use EMACS_INT for count, not int.
18009 (advance_to_char_boundary): Return EMACS_INT, not int.
18011 * data.c (Qcompiled_function): Now static.
18013 * window.c (window_body_lines): Now static.
18015 * image.c (gif_load): Rename local to avoid shadowing.
18017 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18018 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18019 * alloc.c (make_save_value): Integer argument is now of type
18020 ptrdiff_t, not int.
18021 (mark_object): Use ptrdiff_t, not int.
18022 * lisp.h (pD): New macro.
18023 * print.c (print_object): Use it.
18025 * alloc.c: Use EMACS_INT, not int, to count objects.
18026 (total_conses, total_markers, total_symbols, total_vector_size)
18027 (total_free_conses, total_free_markers, total_free_symbols)
18028 (total_free_floats, total_floats, total_free_intervals)
18029 (total_intervals, total_strings, total_free_strings):
18030 Now EMACS_INT, not int. All uses changed.
18031 (Fgarbage_collect): Compute overall total using a double, so that
18032 integer overflow is less likely to be a problem. Check for overflow
18033 when converting back to an integer.
18034 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18035 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18036 These were 'int' variables that could overflow on 64-bit hosts;
18037 they were never used, so remove them instead of repairing them.
18038 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18039 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18040 Previously, this ceilinged at INT_MAX, but that doesn't work on
18042 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18044 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18045 (allocate_vectorlike): Check for ptrdiff_t overflow.
18046 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18047 when a (possibly-narrower) signed value would do just as well.
18048 We prefer using signed arithmetic, to avoid comparison confusion.
18050 * alloc.c: Catch some string size overflows that we were missing.
18051 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18052 for convenience in STRING_BYTES_MAX.
18053 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18054 The definition here is exact; the one in lisp.h was approximate.
18055 (allocate_string_data): Check for string overflow. This catches
18056 some instances we weren't catching before. Also, it catches
18057 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18058 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18059 and ptrdiff_t and EMACS_INT are both 64 bits.
18061 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18062 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18063 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18065 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18067 * alloc.c (Fmake_string): Check for out-of-range init.
18069 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18071 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18073 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18075 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18076 xg_get_default_scrollbar_width.
18078 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18079 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18080 (style_changed_cb): Call update_theme_scrollbar_width and call
18081 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18082 all frames (Bug#8505).
18083 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18084 Call gtk_window_set_resizable if HAVE_GTK3.
18085 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18086 and height if HAVE_GTK3 (Bug#8505).
18087 (scroll_bar_width_for_theme): New variable.
18088 (update_theme_scrollbar_width): New function.
18089 (xg_get_default_scrollbar_width): Move code to
18090 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18091 (xg_initialize): Call update_theme_scrollbar_width.
18093 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18095 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18097 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18099 * frame.c (make_frame): Call other_buffer_safely instead of
18102 * window.c (temp_output_buffer_show): Call display_buffer with
18103 second argument Vtemp_buffer_show_specifiers and reset latter
18104 immediately after the call.
18105 (Vtemp_buffer_show_specifiers): New variable.
18106 (auto_window_vscroll_p, next_screen_context_lines)
18107 (Vscroll_preserve_screen_position): Remove leading asterisks from
18110 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18112 Fix minor problems found by GCC 4.6.0 static checking.
18113 * buffer.c (Qclone_number): Remove for now, as it's unused.
18114 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18115 (record_buffer): Remove unused local.
18116 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18117 (set_frame_buffer_list): Remove; unused.
18118 * frame.h (other_visible_frames): Remove decl.
18119 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18120 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18121 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18123 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18124 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18125 Define only if HAVE_GPM.
18126 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18127 (update_hints_inhibit): Remove; never set. All uses removed.
18128 * widgetprv.h (emacsFrameClassRec): Remove decl.
18129 * window.c (delete_deletable_window): Now returns void, since it
18130 wasn't returning anything.
18131 (compare_window_configurations): Remove unused locals.
18132 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18133 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18134 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18135 the same widths as pointers. This follows up on the 2011-05-06 patch.
18136 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18137 * xterm.h: Likewise.
18138 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18140 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18142 * makefile.w32-in: Update dependencies.
18143 (LISP_H): Add lib/intprops.h.
18145 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18147 * image.c (gif_load): Add animation frame delay to the metadata.
18148 (syms_of_image): Use DEFSYM. New symbol `delay'.
18150 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18152 * window.c (delete_deletable_window): Re-add.
18153 (Fset_window_configuration): Rewrite to handle dead buffers and
18154 consequently deletable windows.
18155 (window_tree, Fwindow_tree): Remove. Supply functionality in
18157 (compare_window_configurations): Simplify code.
18159 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18161 * image.c (imagemagick_load_image): Fix type mismatch.
18162 (Fimagemagick_types): Likewise.
18164 * window.h (replace_buffer_in_windows): Declare.
18166 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18168 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18169 Qclone_number. Remove external declaration of Qdelete_window.
18170 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18172 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18173 Run Qbuffer_list_update_hook if allowed.
18174 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18175 buffer list implementation.
18176 (other_buffer_safely): New function.
18177 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18178 calls to replace_buffer_in_windows and
18179 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18181 (record_buffer): Inhibit quitting and rewrite using quittable
18182 functions. Run Qbuffer_list_update_hook if allowed.
18183 (Frecord_buffer, Funrecord_buffer): New functions.
18184 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18185 Move switch-to-buffer to window.el.
18186 (bury-buffer): Move to window.el.
18187 (Vbuffer_list_update_hook): New variable.
18189 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18192 * window.h (resize_frame_windows): Move up in code.
18193 (Fwindow_frame): Remove EXFUN.
18194 (replace_buffer_in_all_windows): Remove prototype.
18195 (replace_buffer_in_windows_safely): Add prototype.
18197 * window.c: Declare Qdelete_window static again. Move down
18198 declaration of select_count.
18199 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18200 (Fother_window): Move to window.el.
18201 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
18202 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
18203 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
18205 (replace_buffer_in_windows): Implement by calling
18206 Qreplace_buffer_in_windows.
18207 (replace_buffer_in_all_windows): Remove with some functionality
18208 moved into replace_buffer_in_windows_safely.
18209 (replace_buffer_in_windows_safely): New function.
18210 (select_window_norecord, select_frame_norecord): Move in front
18211 of run_window_configuration_change_hook. Remove now obsolete
18213 (Fset_window_buffer): Rewrite doc-string.
18214 Call Qrecord_window_buffer.
18215 (keys_of_window): Move binding for other-window to window.el.
18217 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18219 * dispextern.h (struct image): Replace data member, whose int_val
18220 and ptr_val fields were not used by anything, with a single
18223 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
18224 (gif_clear_image, gif_load, imagemagick_load_image)
18225 (gs_clear_image, gs_load): Callers changed.
18227 2011-06-10 Paul Eggert <eggert@cs.ucla.edu>
18229 * buffer.h: Include <time.h>, for time_t.
18230 Needed to build on FreeBSD 8.2. Problem reported by Herbert J. Skuhra.
18232 Fix minor problems found by static checking.
18234 * image.c (PixelGetMagickColor): Declare if ImageMagick headers don't.
18236 Make identifiers static if they are not used in other modules.

18676 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18677 frame_window_p members of struct bidi_it.
18678 (compute_display_string_pos, compute_display_string_end):
18680 (push_it): Accept second argument POSITION, where pop_it should
18681 jump to continue iteration.
18682 (reseat_1): Initialize bidi_it.disp_pos.
18684 * keyboard.c (adjust_point_for_property): Adjust the call to
18685 display_prop_intangible_p to its new signature.

18695 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
18697 Malloc failure behavior now depends on size of allocation.
18698 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
18699 * lisp.h: Change signatures accordingly.
18700 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18701 All callers changed. (Bug#8762)
18703 * gnutls.c: Use Emacs's memory allocators.
18704 Without this change, the gnutls library would invoke malloc etc.
18705 directly, which causes problems on non-SYNC_INPUT hosts, and which
18706 runs afoul of improving memory_full behavior. (Bug#8761)
18707 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18708 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18709 xfree instead of the default malloc, realloc, free.
18710 (Fgnutls_boot): No need to check for memory allocation failure,
18711 since xmalloc does that for us.
18713 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18714 * category.c (hash_get_category_set):
18715 * ccl.c (ccl_driver):
18716 * charset.c (Fdefine_charset_internal):

18727 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18728 (Fsxhash, Fgethash, Fputhash, Fmaphash):
18729 * image.c (make_image, search_image_cache, lookup_image)
18730 (xpm_put_color_table_h):
18731 * lisp.h (struct Lisp_Hash_Table):
18732 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18733 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18734 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18735 * alloc.c (allocate_vectorlike):
18736 Check for overflow in vector size calculations.
18737 * ccl.c (ccl_driver):
18738 Check for overflow when converting EMACS_INT to int.
18739 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18740 need to be updated by these changes.
18741 * fns.c (make_hash_table, maybe_resize_hash_table):
18742 Check for integer overflow with large hash tables.
18743 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18744 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18745 (SXHASH_REDUCE): New macro.
18746 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18747 Use it instead of discarding useful hash info with large hash values.
18748 (sxhash_float): New function.
18749 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18750 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18751 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18752 Rewrite to use FIXNUM_BITS, as this simplifies things.
18753 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18754 Adjust signatures to match updated version of code.
18755 (consing_since_gc): Now EMACS_INT, since a single hash table can
18756 use more than INT_MAX bytes.
18758 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18760 Make it possible to build with GCC-4.6+ -O2 -flto.
18762 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18764 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18766 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18767 Call minibuffer-inactive-mode.
18769 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18771 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18772 Update dependencies.
18774 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18776 * data.c (init_data): Remove code for UTS, this system is not
18779 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18781 Don't force ./temacs to start in terminal mode.
18783 * frame.c (make_initial_frame): Initialize faces in all cases, not
18784 only when CANNOT_DUMP is defined.
18785 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18787 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18789 * dispnew.c (add_window_display_history): Use const for the string
18790 pointer. Remove declaration, not needed.
18792 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18794 Use 'inline', not 'INLINE'.
18795 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18796 * alloc.c, fontset.c (INLINE): Remove.
18797 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18798 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18799 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18800 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18801 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18803 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18805 Make it possible to run ./temacs.
18807 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18808 syms_of_callproc does the same thing. Remove test for
18809 "initialized", do it in the caller.
18810 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18812 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18814 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18815 (read_minibuf): Use get_minibuffer.
18816 (syms_of_minibuf): Use DEFSYM.
18817 (Qmetadata): New var.
18818 * data.c (Qbuffer): Don't make it static.
18819 (syms_of_data): Use DEFSYM.
18821 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18823 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18824 (CCL_CODE_MIN): New macro.
18826 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18828 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18830 * eval.c (Qdebug): Now static.
18831 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18832 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18833 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18835 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18837 * image.c: Various fixes to ImageMagick code comments.
18838 (Fimagemagick_types): Doc fix.
18840 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18842 Minor fixes prompted by GCC 4.6.0 warnings.
18844 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18846 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18847 (x_clipboard_manager_save_all): Move extern decl to ...
18848 * xterm.h: ... here, so that it can be checked for consistency.
18850 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18852 * xselect.c (x_clipboard_manager_save_frame)
18853 (x_clipboard_manager_save_all): New functions.
18854 (Fx_clipboard_manager_save): Lisp function deleted.
18856 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18857 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18859 * xterm.h: Update prototype.
18861 2011-05-28 William Xu <william.xwl@gmail.com>
18863 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18864 exiting (Bug#8239).
18866 2011-05-28 Jim Meyering <meyering@redhat.com>
18868 Avoid a sign-extension bug in crypto_hash_function.
18869 * fns.c (to_uchar): Define.
18870 (crypto_hash_function): Use it to convert some newly-signed
18871 variables to unsigned, to avoid sign-extension bugs. For example,
18872 without this change, (md5 "truc") would evaluate to
18873 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18874 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18875 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18877 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18879 Integer overflow fixes.
18881 * dbusbind.c: Serial number integer overflow fixes.
18882 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18883 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18884 to hold a serial number that is too large for a fixnum.
18885 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18886 Check for serial numbers out of range. Decode any serial number
18887 that was so large that it became a float. (Bug#8722)
18889 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18890 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18891 Use XFASTINT rather than XUINT when numbers are nonnegative.
18892 (xd_append_arg, Fdbus_method_return_internal):
18893 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18894 arguments, check that Lisp number is nonnegative, rather than
18895 silently wrapping negative numbers around. (Bug#8722)
18896 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18899 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18901 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18903 ccl: Add integer overflow checks.
18904 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18905 (IN_INT_RANGE): New macros.
18906 (ccl_driver): Use them to check for integer overflow when
18907 decoding a CCL program. Many of the new checks are whether XINT (x)
18908 fits in int; it doesn't always, on 64-bit hosts. The new version
18909 doesn't catch all possible integer overflows, but it's an
18910 improvement. (Bug#8719)
18912 * alloc.c (make_event_array): Use XINT, not XUINT.
18913 There's no need for unsigned here.
18915 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18916 This follows up to the 2011-05-06 change that substituted uintptr_t
18917 for EMACS_INT. This case wasn't caught back then.
18919 Rework Fformat to avoid integer overflow issues.
18920 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18921 now (part of C89). Include <verify.h>.
18922 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18923 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18924 (Fformat): Avoid the prepass trying to compute sizes; it was only
18925 approximate and thus did not catch overflow reliably. Instead, walk
18926 through the format just once, formatting and computing sizes as we go,
18927 checking for integer overflow at every step, and allocating a larger
18928 buffer as needed. Keep track separately whether the format is
18929 multibyte. Keep only the most-recently calculated precision, rather
18930 than them all. Record whether each argument has been converted to
18931 string. Use EMACS_INT, not int, for byte and char and arg counts.
18932 Support field widths and precisions larger than INT_MAX. Avoid
18933 sprintf's undefined behavior with conversion specifications such as %#d
18934 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18935 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18936 formatting out-of-range floating point numbers with int
18937 formats. (Bug#8668)
18939 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18941 * data.c: Avoid integer truncation in expressions involving floats.
18942 * data.c: Include <intprops.h>.
18943 (arith_driver): When there's an integer overflow in an expression
18944 involving floating point, convert the integers to floating point
18945 so that the resulting value does not suffer from catastrophic
18946 integer truncation. For example, on a 64-bit host (* 4
18947 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18948 Do not rely on undefined behavior after integer overflow.
18950 merge count_size_as_multibyte, parse_str_to_multibyte
18951 * character.c, character.h (count_size_as_multibyte):
18952 Rename from parse_str_to_multibyte; all uses changed.
18953 Check for integer overflow.
18954 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18955 since it's now a duplicate of the other. This is more of
18956 a character than a buffer op, so better that it's in character.c.
18957 * fns.c, print.c: Adjust to above changes.
18959 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18961 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18963 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18965 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18966 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18967 (x_clipboard_manager_save): Now static.
18968 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18970 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18971 (crypto_hash_function): Now static.
18972 Fix pointer signedness problems. Avoid unnecessary initializations.
18974 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18976 * termhooks.h (Vselection_alist): Make it terminal-local.
18978 * terminal.c (create_terminal): Initialize it.
18980 * xselect.c: Support for clipboard managers.
18981 (Vselection_alist): Move to termhooks.h as terminal-local var.
18982 (LOCAL_SELECTION): New macro.
18983 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18984 (symbol_to_x_atom): Remove gratuitous arg.
18985 (x_handle_selection_request, lisp_data_to_selection_data)
18986 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18987 (x_own_selection, x_get_local_selection, x_convert_selection):
18988 New arg, specifying work frame. Use terminal-local Vselection_alist.
18989 (some_frame_on_display): Delete unused function.
18990 (Fx_own_selection_internal, Fx_get_selection_internal)
18991 (Fx_disown_selection_internal, Fx_selection_owner_p)
18992 (Fx_selection_exists_p): New optional frame arg.
18993 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18994 (x_handle_selection_clear): Don't treat other terminals with the
18995 same keyboard specially. Use the terminal-local Vselection_alist.
18996 (x_clear_frame_selections): Use Frun_hook_with_args.
18998 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19000 * xterm.h: Add support for those atoms.
19002 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19004 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19005 (converted_selections, conversion_fail_tag): New global variables.
19006 (x_selection_request_lisp_error): Free the above.
19007 (x_get_local_selection): Remove unnecessary code.
19008 (x_reply_selection_request): Args changed; handle arbitrary array
19009 of converted selections stored in converted_selections.
19010 Separate the XChangeProperty and SelectionNotify steps.
19011 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19012 (x_convert_selection): New function.
19013 (x_handle_selection_event): Simplify.
19014 (x_get_foreign_selection): Don't ignore incoming requests while
19015 waiting for an answer; this will fail when we implement
19016 SAVE_TARGETS, and seems unnecessary anyway.
19017 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19018 (Vx_sent_selection_functions): Doc fix.
19020 2011-05-26 Leo Liu <sdl.web@gmail.com>
19022 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19024 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19026 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19028 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19029 for fringe update if it has periodic bitmap.
19030 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19031 and fringe_bitmap_periodic_p.
19033 * fringe.c (get_fringe_bitmap_data): New function.
19034 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19035 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19036 row. Mark glyph row for fringe update if periodicity changed.
19038 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19039 for fringe update unless it has periodic bitmap.
19041 2011-05-25 Kenichi Handa <handa@m17n.org>

19060 Remove macros that are defined and never used.
19061 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19063 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19065 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19066 (Fx_get_selection_internal): Minor cleanup.

19094 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19096 * systime.h (Time): Define only if emacs is defined.
19097 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19098 where the include path doesn't have X11/X.h by default. See
19099 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19101 2011-05-20 Kenichi Handa <handa@m17n.org>
19103 * composite.c (find_automatic_composition): Fix previous change.
19105 2011-05-20 Glenn Morris <rgm@gnu.org>

19110 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19112 2011-05-19 Glenn Morris <rgm@gnu.org>
19114 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19115 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19116 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19117 (lisp): Set the order to that of loadup.el.
19118 (shortlisp): Make it a copy of $lisp.
19119 (SOME_MACHINE_LISP): Remove.
19120 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19121 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19123 2011-05-18 Kenichi Handa <handa@m17n.org>
19125 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19126 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19127 (find_automatic_composition): Mostly rewrite for efficiency.
19129 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19131 * makefile.w32-in: Update dependencies.
19133 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19135 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19136 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19138 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19140 Fix some integer overflow issues, such as string length overflow.
19142 * insdel.c (count_size_as_multibyte): Check for string overflow.
19144 * character.c (lisp_string_width): Check for string overflow.
19145 Use EMACS_INT, not int, for string indexes and lengths; in
19146 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19147 the resulting string length overflows an EMACS_INT; instead,
19148 report a string overflow if no precision given. When checking for
19149 precision exhaustion, use a check that cannot possibly have
19150 integer overflow. (Bug#8675)
19151 * character.h (lisp_string_width): Adjust to new signature.
19153 * alloc.c (string_overflow): New function.
19154 (Fmake_string): Use it. This doesn't change behavior, but saves
19155 a few bytes and will simplify future changes.
19156 * character.c (string_escape_byte8): Likewise.
19157 * lisp.h (string_overflow): New decl.
19159 Fixups, following up to the user-interface timestamp change.
19160 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19161 for UI timestamps, instead of unsigned long.
19162 * msdos.c (mouse_get_pos): Likewise.
19163 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19164 * w32gui.h (Time): Define by including "systime.h" rather than by
19165 declaring it ourselves. (Bug#8664)
19167 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19168 * image.c (clear_image_cache): Likewise.
19170 * term.c (term_mouse_position): Don't assume time_t wraparound.
19172 Be more systematic about user-interface timestamps.
19173 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19174 and sometimes 'EMACS_UINT', to represent these timestamps.
19175 This change causes it to use 'Time' uniformly, as that's what X uses.
19176 This makes the code easier to follow, and makes it easier to catch
19177 integer overflow bugs such as Bug#8664.
19178 * frame.c (Fmouse_position, Fmouse_pixel_position):
19179 Use Time, not unsigned long, for user-interface timestamps.
19180 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19181 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19182 * keyboard.h (last_event_timestamp): Likewise.
19183 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19184 * menu.h (xmenu_show): Likewise.
19185 * term.c (term_mouse_position): Likewise.
19186 * termhooks.h (struct input_event.timestamp): Likewise.
19187 (struct terminal.mouse_position_hook): Likewise.
19188 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19189 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19190 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19191 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19192 what it was before.
19193 * menu.h, termhooks.h: Include "systime.h", for Time.
19195 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19196 Don't assume that the difference between two unsigned long values
19197 can fit into an integer. At this point, we know button_down_time
19198 <= event->timestamp, so the difference must be nonnegative, so
19199 there's no need to cast the result if double-click-time is
19200 nonnegative, as it should be; check that it's nonnegative, just in
19201 case. This bug is triggered when events are more than 2**31 ms
19202 apart (about 25 days). (Bug#8664)
19204 * xselect.c (last_event_timestamp): Remove duplicate decl.
19205 (x_own_selection): Remove needless cast to unsigned long.
19207 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19208 that always fit in int. Use a sentinel instead of a counter, to
19209 avoid a temp and to allay GCC's concerns about possible int overflow.
19210 * frame.h (struct frame): Use int for menu_bar_items_used
19211 instead of EMACS_INT, since it always fits in int.
19213 * menu.c (grow_menu_items): Check for int overflow.
19215 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19217 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19218 Before, the code was not consistent. These values cannot exceed
19219 2**31 - 1 so there's no need to make them unsigned.
19220 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19221 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19222 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19224 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19226 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19227 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19228 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19229 presumably because the widths might not match.
19231 * window.c (size_window): Avoid needless test at loop start.
19233 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19235 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19237 2011-05-12 Drew Adams <drew.adams@oracle.com>
19239 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19241 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19243 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19244 `width' to `bar_area_x' and `bar_area_width', respectively.
19245 (x_scroll_run): Take account of fringe background extension.
19247 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19248 Rename local vars `left' and `width' to `bar_area_x' and
19249 `bar_area_width', respectively.
19250 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19251 background extension.
19253 2011-05-10 Jim Meyering <meyering@redhat.com>
19255 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19257 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19259 * image.c (Finit_image_library): Return t for built-in image types,
19260 like pbm and xbm. (Bug#8640)
19262 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19264 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19266 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19268 * w32console.c (Fset_screen_color): Doc fix.
19269 (Fget_screen_color): New function.
19270 (syms_of_ntterm): Defsubr it.
19272 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19273 unlink the temporary file if Fcall_process didn't create it in the
19275 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19276 child process will be redirected to a file specified with `:file'.
19277 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19278 cue to call_process_cleanup not to close that handle.
19280 2011-05-07 Ben Key <bkey76@gmail.com>
19282 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19283 one of two shell specific rules, either bootstrap-temacs-CMD or
19284 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19285 to the previous implementation of the bootstrap-temacs rule.
19286 The bootstrap-temacs-CMD rule is similar to the previous
19287 implementation of the bootstrap-temacs rule except that it
19288 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19291 These changes, along with some changes to nt/configure.bat,
19292 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19293 earlier fix to add support for --cflags and --ldflags options
19294 that include quotes so that it works whether make uses cmd or
19297 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19299 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19300 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19302 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19303 a string. Handle both cases.
19304 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19305 (Fdbus_register_method): Use Qinvalid_function.
19307 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19309 * makefile.w32-in: Update dependencies.
19310 (LISP_H): Add inttypes.h and stdin.h.
19311 (PROCESS_H): Add unistd.h.
19313 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19315 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19316 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19318 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19320 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19322 * term.c (vfatal): Remove stray call to va_end.
19323 It's not needed and the C Standard doesn't allow it here anyway.
19325 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19326 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19328 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19331 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19333 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19335 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19337 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19339 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19341 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19342 * charset.c (Fdefine_charset_internal): Don't initialize
19343 charset.code_space[15]. The value was garbage, on hosts with
19344 32-bit int (Bug#8600).
19346 * lread.c (read_integer): Be more consistent with string-to-number.
19347 Use string_to_number to do the actual conversion; this avoids
19348 rounding errors and fixes some other screwups. Without this fix,
19349 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19350 (digit_to_number): Move earlier, for benefit of read_integer.
19351 Return -1 if the digit is out of range for the base, -2 if it is
19352 not a digit in any supported base. (Bug#8602)
19354 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19356 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19357 to match comment at start of function. This also removes a
19358 GCC warning about overflow in a 32+64-bit port.
19360 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19362 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19363 Reported by Stefan Monnier in
19364 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19365 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19366 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19368 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19369 (EMACS_UINTPTR): Likewise, with uintptr_t.
19371 * lisp.h: Prefer 64-bit EMACS_INT if available.
19372 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19373 on 32-bit hosts that have 64-bit int, so that they can access
19375 However, temporarily disable this change unless the temporary
19376 symbol WIDE_EMACS_INT is defined.
19378 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19380 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19381 This removes an assumption that EMACS_INT and long are the same
19382 width as pointers. The assumption is true for Emacs porting targets
19383 now, but we want to make other targets possible.
19384 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19385 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19386 In the rest of the code, change types of integers that hold casted
19387 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19388 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19389 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19390 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19391 No need to cast type when ORing.
19392 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19393 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19394 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19395 assume EMACS_INT is the same width as char *.
19396 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19397 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19398 Remove no-longer-needed casts.
19399 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19400 (xg_tool_bar_help_callback, xg_make_tool_item):
19401 Use EMACS_INTPTR to hold an integer
19402 that will be cast to void *; this can avoid a GCC warning
19403 if EMACS_INT is not the same width as void *.
19404 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19405 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19406 (current_message_1, set_message_1):
19407 Use a local to convert to proper width without a cast.
19408 * xmenu.c (dialog_selection_callback): Likewise.
19410 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19411 Also, don't assume VALBITS / RAND_BITS is less than 5,
19412 and don't rely on undefined behavior when shifting a 1 left into
19414 * lisp.h (get_random): Change signature to match.
19416 * lread.c (hash_string): Use size_t, not int, for hash computation.
19417 Normally we prefer signed values; but hashing is special, because
19418 it's better to use unsigned division on hash table sizes so that
19419 the remainder is nonnegative. Also, size_t is the natural width
19420 for hashing into memory. The previous code used 'int', which doesn't
19421 retain enough info to hash well into very large tables.
19422 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19424 * dbusbind.c: Don't possibly lose pointer info when converting.
19425 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19426 Use XPNTR rather than XHASH, so that the high-order bits of
19427 the pointer aren't lost when converting through void *.
19429 * eval.c (Fautoload): Don't double-shift a pointer.
19431 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19433 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19435 * gnutls.c (DEF_GNUTLS_FN):
19436 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19438 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19440 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19443 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19445 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19446 New version that can reserve upto 2GB of heap space.
19448 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19450 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19452 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19454 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19455 `gnutls_certificate_set_x509_key_file'.
19457 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19459 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19460 Update dependencies.
19462 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19464 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19465 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19466 Remove unused parameter `fildes'.
19467 * process.c (read_process_output, send_process): Don't pass it.
19469 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19471 Fix previous change: the library cache is defined in w32.c.
19472 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19473 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19475 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19477 Implement dynamic loading of GnuTLS on Windows.
19479 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19480 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19481 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19484 * gnutls.c (Qgnutls_dll): Define.
19485 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19486 (gnutls_*): Declare function pointers.
19487 (init_gnutls_functions): New function to initialize function pointers.
19488 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19489 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19490 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19491 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19492 (emacs_gnutls_write, emacs_gnutls_read)
19493 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19494 (Fgnutls_available_p): New function.
19495 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19496 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19497 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19499 * image.c: Include w32.h.
19500 (Vimage_type_cache): Delete.
19501 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19502 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19503 (w32_delayed_load): Move to w32.c.
19505 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19507 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19508 (w32_delayed_load): Move from image.c. When loading a library, record
19509 its filename in the :loaded-from property of the library id.
19510 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19511 Initialize and staticpro them.
19512 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19514 * process.c: Include lisp.h before w32.h, not after.
19515 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19516 instead of gnutls_record_check_pending.
19518 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19520 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19522 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19523 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19526 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19528 * xterm.c (x_set_frame_alpha): Do not set property on anything

19568 rather than `XVECTOR (FOO)->size'.
19570 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19571 inttypes.h, as a gnulib replacement is used if it not available in

19584 space for up to 2 characters produced in a loop.
19585 (decode_coding_iso_2022): Abort if there isn't enough place in
19586 charbuf for the composition carryover bytes.
19588 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19590 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19591 aborting when %lld or %lll format is passed.

19593 %llo or %llx format is passed. (Bug#8545)
19595 * window.c (window_scroll_line_based): Use a marker instead of
19596 simple variables to record original value of point. (Bug#7952)
19598 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19599 produced by %s or %c overflows available buffer space. (Bug#8545)
19601 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19603 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19604 (SIZE_MAX): Move defn after all includes, as they might #define it.
19606 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19608 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19610 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19612 * keyboard.c (Qdelayed_warnings_hook): Define.
19613 (command_loop_1): Run `delayed-warnings-hook'
19614 if Vdelayed_warnings_list is non-nil.
19615 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19616 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19618 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19620 * doprnt.c (doprnt): Don't return value smaller than the buffer
19621 size if the message was truncated. (Bug#8545).
19623 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19625 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

19628 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19630 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19632 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19634 * makefile.w32-in: Update dependencies.
19636 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19638 Improve `doprnt' and its usage. (Bug#8545)
19639 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19640 `format_end'. Remove support for %l as a conversion specifier.
19641 Don't use xrealloc. Improve diagnostics when the %l size modifier
19642 is used. Update the commentary.
19644 * eval.c (verror): Simplify calculation of size_t.
19646 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19649 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19651 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19654 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19656 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19657 This makes this file independent of the recent pseudovector change.
19659 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19661 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19663 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19664 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19665 Remove unused local.
19666 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19668 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19669 GCC 4.6.0 optimizes based on type-based alias analysis.
19670 For example, if b is of type struct buffer * and v of type struct
19671 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19672 != &v->size, and therefore "v->size = 1; b->size = 2; return
19673 v->size;" must therefore return 1. This assumption is incorrect
19674 for Emacs, since it type-puns struct Lisp_Vector * with many other
19675 types. To fix this problem, this patch adds a new type struct
19676 vectorlike_header that documents the constraints on layout of vectors
19677 and pseudovectors, and helps optimizing compilers not get fooled
19678 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19679 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19680 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19682 (XSETPVECTYPE): Rewrite in terms of new macro.
19683 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19684 This is a bit clearer, and further avoids the possibility of
19685 undesirable aliasing.
19686 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19687 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19688 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19689 since Lisp_Subr is a special case (no "next" field).
19690 (ASIZE): Now uses header.size rather than size.
19691 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19692 to avoid the hassle of writing XVECTOR (foo)->header.size.
19693 (struct vectorlike_header): New type.
19694 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19695 object, to help avoid aliasing.
19696 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19697 (SUBRP): Likewise, since Lisp_Subr is a special case.
19698 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19699 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19700 (struct Lisp_Hash_Table): Combine first two members into a single
19701 struct vectorlike_header member. All uses of "size" and "next" members
19702 changed to be "header.size" and "header.next".
19703 * buffer.h (struct buffer): Likewise.
19704 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19705 * frame.h (struct frame): Likewise.
19706 * process.h (struct Lisp_Process): Likewise.
19707 * termhooks.h (struct terminal): Likewise.
19708 * window.c (struct save_window_data, struct saved_window): Likewise.
19709 * window.h (struct window): Likewise.
19710 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19711 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19712 * buffer.c (init_buffer_once): Likewise.
19713 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19715 * process.c (Fformat_network_address): Use local var for size,
19718 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19720 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19721 * data.c (atof): Remove decl; no longer used or needed.
19722 (digit_to_number): Move to lread.c.
19723 (Fstring_to_number): Use new string_to_number function, to be
19724 consistent with how the Lisp reader treats infinities and NaNs.
19725 Do not assume that floating-point numbers represent EMACS_INT
19726 without losing information; this is not true on most 64-bit hosts.
19727 Avoid double-rounding errors, by insisting on integers when
19728 parsing non-base-10 numbers, as the documentation specifies.
19729 * lisp.h (string_to_number): New decl, replacing ...
19730 (isfloat_string): Remove.
19731 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19732 (read1): Do not accept +. and -. as integers; this
19733 appears to have been a coding error. Similarly, do not accept
19734 strings like +-1e0 as floating point numbers. Do not report
19735 overflow for integer overflows unless the base is not 10 which
19736 means we have no simple and reliable way to continue.
19737 Break out the floating-point parsing into a new
19738 function string_to_number, so that Fstring_to_number parses
19739 floating point numbers consistently with the Lisp reader.
19740 (digit_to_number): Move here from data.c. Make it static inline.
19741 (E_CHAR, EXP_INT): Remove, replacing with ...
19742 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19743 (string_to_number): New function, replacing isfloat_string.
19744 This function checks for valid syntax and produces the resulting
19745 Lisp float number too. Rework it so that string-to-number
19746 no longer mishandles examples like "1.0e+". Use strtoumax,
19747 so that overflow for non-base-10 numbers is reported only when
19748 there's no portable and simple way to convert to floating point.
19750 * textprop.c (set_text_properties_1): Rewrite for clarity,
19751 and to avoid GCC warning about integer overflow.
19753 * intervals.h (struct interval): Use EMACS_INT for members
19754 where EMACS_UINT might cause problems. See
19755 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19756 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19757 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19759 (offset_intervals): Tell GCC not to worry about length overflow
19760 when negating a negative length.
19762 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19763 (overrun_check_free): Likewise.
19765 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19766 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19769 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19770 (gnutls_make_error): Rename local to avoid shadowing.
19771 (gnutls_emacs_global_deinit): ifdef out; not used.
19772 (Fgnutls_boot): Use const for pointer to readonly storage.
19773 Comment out unused local. Fix pointer signedness problems.
19775 * lread.c (openp): Don't stuff size_t into an 'int'.
19776 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19777 about possible signed overflow.
19779 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19780 (GDK_KEY_g): Don't define if already defined.
19781 (xg_prepare_tooltip): Avoid pointer signedness problem.
19782 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19784 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19785 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19787 * xfns.c (Fx_window_property): Simplify a bit,
19788 to make a bit faster and to avoid GCC 4.6.0 warning.
19789 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19791 * fns.c (internal_equal): Don't assume size_t fits in int.
19793 * alloc.c (compact_small_strings): Tighten assertion a little.
19795 Replace pEd with more-general pI, and fix some printf arg casts.
19796 * lisp.h (pI): New macro, generalizing old pEd macro to other
19797 conversion specifiers. For example, use "...%"pI"d..." rather
19798 than "...%"pEd"...".
19799 (pEd): Remove. All uses replaced with similar uses of pI.
19800 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19801 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19802 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19803 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19804 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19805 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19806 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19808 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19809 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19810 * print.c (safe_debug_print, print_object): Likewise.
19811 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19813 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19814 avoiding the 0 flag, which is not portable.
19815 * process.c (Fmake_network_process): Use pI to avoid cast.
19816 * region-cache.c (pp_cache): Likewise.
19817 * xdisp.c (decode_mode_spec): Likewise.
19818 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19819 behavior on 64-bit hosts with printf arg.
19820 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19821 (x_stop_queuing_selection_requests): Likewise.
19822 (x_get_window_property): Don't truncate byte count to an 'int'
19825 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19826 here, since it parses constructs like leading '-' and spaces,
19827 which are not wanted; and it overflows with large numbers.
19828 Instead, simply match F[0-9]+, which is what is wanted anyway.
19830 * alloc.c: Remove unportable assumptions about struct layout.
19831 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19832 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19833 (allocate_vectorlike, make_pure_vector): Use the new macros,
19834 plus offsetof, to remove unportable assumptions about struct layout.
19835 These assumptions hold on all porting targets that I know of, but
19836 they are not guaranteed, they're easy to remove, and removing them
19837 makes further changes easier.
19839 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19840 This doesn't fix a bug but makes the code clearer.
19841 (string_overrun_cookie): Now const. Use initializers that
19842 don't formally overflow signed char, to avoid warnings.
19843 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19844 can cause Emacs to crash when string overrun checking is enabled.
19845 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19846 multiple of sizeof (EMACS_INT); it need not be, if
19847 alignof(EMACS_INT) < sizeof (EMACS_INT).
19848 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19850 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19854 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19856 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19857 supposed to be handshaking. (Bug#8556)
19858 Reported by Paul Eggert <eggert@cs.ucla.edu>.

19865 (handle_user_signal): Break into debugger when debug-on-event
19866 matches the current signal symbol.
19868 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19870 * alloc.c (check_sblock, check_string_bytes)
19871 (check_string_free_list): Convert to standard C.
19873 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19875 * w32.c (emacs_gnutls_push): Fix typo.
19877 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19879 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19880 "cast to pointer from integer of different size".
19882 Improve doprnt and its use in verror. (Bug#8545)
19883 * doprnt.c (doprnt): Document the set of format control sequences
19884 supported by the function. Use SAFE_ALLOCA instead of always
19887 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19888 is one byte too soon. Don't use xrealloc; instead xfree and
19891 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19893 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19896 * gnutls.c: Renamed global_initialized to
19897 gnutls_global_initialized. Added internals for the
19898 :verify-hostname-error, :verify-error, and :verify-flags
19899 parameters of `gnutls-boot' and documented those parameters in the
19900 docstring. Start callback support.
19901 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19902 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19903 on error. Return error code.
19904 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19905 (emacs_gnutls_read): Likewise.
19906 (Fgnutls_boot): Return handshake error code.
19907 (emacs_gnutls_handle_error): New function.
19908 (wsaerror_to_errno): Likewise.

19911 (emacs_gnutls_push): Likewise.
19913 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
19914 (emacs_gnutls_push): Likewise.
19916 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
19918 * process.c (wait_reading_process_output): Check if GnuTLS
19919 buffered some data internally if no FDs are set for TLS
19922 * makefile.w32-in (OBJ2): Add gnutls.$(O).
19923 (LIBS): Link to USER_LIBS.

19928 * xdisp.c (handle_single_display_spec): Rename the
19929 display_replaced_before_p argument into display_replaced_p, to
19930 make it consistent with the commentary. Fix typos in the
19933 * textprop.c (syms_of_textprop): Remove dead code.

19939 to changes in oldXMenu/XMenu.h from 2011-04-16.
19940 <menu_help_message, prev_menu_help_message>: Constify.
19941 (IT_menu_make_room): menu->help_text is now `const char **';

19957 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
19959 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
19962 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
19963 changes in globals.h immediately force recompilation.
19964 (TAGS): Depend on $(CURDIR)/m/intel386.h and

20231 * process.c (send_process): Adjust to the new signatures of
20232 emacs_write and emacs_gnutls_write. Do not attempt to store

20433 since 0 is always ASCII.
20435 * fns.c (weak_hash_tables): Now static.
20437 * fileio.c: Make symbols static if they're not exported.
20438 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

20456 * editfns.c, lisp.h (get_operating_system_release): Remove.
20457 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20458 worth the hassle of breaking this out.
20460 * xterm.c: Make symbols static if they're not exported.
20461 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

20575 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20576 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20577 was inaccessible from Lisp.
20578 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20579 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20581 alloc.c: Import and export fewer symbols, and remove unused items.
20582 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING

20598 (mark_backtrace): Define only if BYTE_MARK_STACK.
20599 * xdisp.c (message_enable_multibyte): Now static.
20601 Declare Lisp_Object Q* variables to be 'static' if not exported.
20602 This makes it easier for human readers (and static analyzers)
20603 to see whether these variables are used from other modules.
20604 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20605 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

20615 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20617 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20619 Make Emacs functions such as Fatom 'static' by default.
20620 This makes it easier for human readers (and static analyzers)
20621 to see whether these functions can be called from other modules.
20622 DEFUN now defines a static function. To make the function external
20623 so that it can be used in other C modules, use the new macro DEFUE.
20624 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20625 (Finit_image_library):
20626 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20627 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20628 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20629 Remove decls, since these functions are now static.
20630 (Funintern, Fget_internal_run_time): New decls, since these functions
20631 were already external.
20633 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20634 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20641 Mark functions with DEFUE instead of DEFUN,
20642 if they are used in other modules.
20643 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20644 decls for now-static functions.
20645 * buffer.h (Fdelete_overlay): Remove decl.
20646 * callproc.c (Fgetenv_internal): Mark as internal.

20655 * image.c (Finit_image_library): New forward static decl.
20656 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20657 * intervals.h (Fprevious_property_change):
20658 (Fremove_list_of_text_properties): Remove decls.
20659 * keyboard.c (Fthis_command_keys): Remove decl.
20660 (Fcommand_execute): New forward static decl.

20676 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
20678 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20681 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20683 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20684 when at ZV. (Bug#8487)
20686 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20688 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20691 * sound.c (sound_cleanup, alsa_close): Likewise.
20692 * termcap.c (tgetent): Likewise.

20694 * xsettings.c (read_and_apply_settings): Likewise.
20696 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20697 (overrun_check_free): Protoize.
20699 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20701 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20702 since callers should never pass a negative size.
20703 Change the signature to match that of plain 'read' and 'write'; see
20704 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20705 * lisp.h: Update prototypes of emacs_write and emacs_read.
20707 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20709 * xdisp.c (redisplay_window): Don't try to determine the character
20710 position of the scroll margin if the window start point w->startp
20711 is outside the buffer's accessible region. (Bug#8468)
20713 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20715 Fix write-region and its subroutines for buffers > 2GB.
20716 * fileio.c (a_write, e_write): Modify declaration of arguments and
20717 local variables to support buffers larger than 2GB.
20718 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20720 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20721 argument, local variables, and return value.
20723 * lisp.h: Update prototypes of emacs_write and emacs_read.
20725 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20727 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20729 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20731 Fix more problems found by GCC 4.6.0's static checks.
20733 * xdisp.c (vmessage): Use a better test for character truncation.
20735 * charset.c (load_charset_map): <, not <=, for optimization,
20736 and to avoid potential problems with integer overflow.
20737 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20738 * casetab.c (set_identity, shuffle): Likewise.
20739 * editfns.c (Fformat): Likewise.
20740 * syntax.c (skip_chars): Likewise.
20742 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20743 This also lets GCC 4.6.0 generate slightly better loop code.
20745 * callint.c (Fcall_interactively): <, not <=, for optimization.
20746 (Fcall_interactively): Count the number of arguments produced,
20747 not the number of arguments given. This is simpler and lets GCC
20748 4.6.0 generate slightly better code.
20750 * ftfont.c: Distingish more carefully between FcChar8 and char.
20751 The previous code passed unsigned char * to a functions like
20752 strlen and xstrcasecmp that expect char *, which does not
20753 conform to the C standard.
20754 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20755 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20756 char * when the C standard requires it.
20758 * keyboard.c (read_char): Remove unused var.
20760 * eval.c: Port to Windows vsnprintf (Bug#8435).
20761 Include <limits.h>.
20762 (SIZE_MAX): Define if the headers do not.
20763 (verror): Do not give up if vsnprintf returns a negative count.
20764 Instead, grow the buffer. This ports to Windows vsnprintf, which
20765 does not conform to C99. Problem reported by Eli Zaretskii.
20766 Also, simplify the allocation scheme, by avoiding the need for
20767 calling realloc, and removing the ALLOCATED variable.
20769 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20771 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20772 But keep the doprint source code for now, as we might revamp it
20773 and use it again (Bug#8435).
20774 * lisp.h (doprnt): Remove.
20775 * Makefile.in (base_obj): Remove doprnt.o.
20776 * deps.mk (doprnt.o): Remove.
20778 error: Print 32- and 64-bit integers portably (Bug#8435).
20779 Without this change, on typical 64-bit hosts error ("...%d...", N)
20780 was used to print both 32- and 64-bit integers N, which relied on
20781 undefined behavior.
20782 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20783 * lisp.h (error, verror): Mark as printf-like functions.
20784 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20785 Report overflow in size calculations when allocating printf buffer.
20786 Do not truncate output string at its first null byte.
20787 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20788 Truncate the output at a character boundary, since vsnprintf does not
20790 * charset.c (check_iso_charset_parameter): Convert internal
20791 character to string before calling 'error', since %c now has the
20793 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20794 overflow when computing char to be passed to 'error'. Do not
20795 pass Lisp_Object to 'error'; pass the integer instead.
20796 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20797 formatted with plain %d.
20799 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20801 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20803 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20805 * xterm.c (x_catch_errors): Remove duplicate declaration.
20807 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20809 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20811 2011-04-10 Jim Meyering <meyering@redhat.com>
20813 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20814 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20815 return ssize_t not "int", and use size_t as the buffer length.
20816 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20817 * gnutls.h: Update declarations.
20818 * process.c (read_process_output): Use ssize_t, to match.
20819 (send_process): Likewise.
20821 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20823 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20825 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20827 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20828 Use unsigned char, to match FcChar8 type definition.
20830 * xterm.c (handle_one_xevent):
20831 * xmenu.c (create_and_show_popup_menu):
20832 * xselect.c (x_decline_selection_request)
20833 (x_reply_selection_request): Avoid type-punned deref of X events.
20835 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20837 Fix some uses of `int' instead of EMACS_INT.
20838 * search.c (string_match_1, fast_string_match)
20839 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20840 (scan_buffer, find_next_newline_no_quit)

20842 (Fmatch_data): Make some `int' variables be EMACS_INT.
20844 * xdisp.c (display_count_lines): 3rd argument and return value now
20845 EMACS_INT. All callers changed.
20846 (pint2hrstr): Last argument is now EMACS_INT.

20865 (encode_invocation_designation): Last argument P_NCHARS is now
20867 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20868 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20870 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.

20888 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20890 * keyboard.c (read_char): Call Lisp function help-form-show,
20891 instead of using internal_with_output_to_temp_buffer.
20892 (Qhelp_form_show): New var.
20893 (syms_of_keyboard): Use DEFSYM macro.
20895 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20906 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20908 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20910 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20912 Fix more problems found by GCC 4.6.0's static checks.
20914 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

20918 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20920 * xdisp.c (vmessage): Mark as a printf-like function.
20922 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20929 to system-supplied API.
20931 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20933 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20934 This avoids several warnings with gcc -Wstrict-overflow.
20935 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20936 directly, rather than having caller test rule sign. This avoids
20937 some unnecessary tests.
20938 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20939 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20940 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20942 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20943 (xfont_open): Avoid unnecessary tests.
20945 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20947 * composite.h, composite.c (composition_gstring_put_cache):
20948 Use EMACS_INT, not int, for length.
20950 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20951 breaking out part of COMPOSITION_DECODE_RULE.
20952 (COMPOSITION_DECODE_RULE): Use it.
20953 * composite.c (get_composition_id): Remove unused local vars,
20954 by using the new macro.
20956 * textprop.c (set_text_properties_1): Change while to do-while,
20957 since the condition is always true at first.
20959 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20960 (interval_deletion_adjustment): Return unsigned value.
20963 * process.c (list_processes_1, create_pty, read_process_output):
20964 (exec_sentinel): Remove vars that were set but not used.
20965 (create_pty): Remove unnecessary "volatile"s.
20966 (Fnetwork_interface_info): Avoid possibility of int overflow.
20967 (read_process_output): Do adaptive read buffering even if carryover.
20968 (read_process_output): Simplify nbytes computation if buffered.

20979 * print.c (print_error_message): Avoid int overflow.
20981 * font.c (font_list_entities): Redo for clarity,
20982 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20984 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20985 (font_score): Avoid potential overflow in diff calculation.
20987 * fns.c (substring_both): Remove var that is set but not used.
20988 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20990 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20992 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20993 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20994 can always succeed if overflow has undefined behavior.
20996 * search.c (boyer_moore, wordify): Remove vars set but not used.
20997 (wordify): Omit three unnecessary tests.
20999 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21000 All callers changed. This avoids the need for an unused var.
21002 * casefiddle.c (casify_region): Remove var that is set but not used.
21004 * dired.c (file_name_completion): Remove var that is set but not used.
21006 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21008 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21009 (Finsert_file_contents): Remove unnecessary code checking fd.
21011 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21012 Check for integer overflow on size calculations.
21014 * buffer.c (Fprevious_overlay_change): Remove var that is set
21017 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21018 Remove vars that are set but not used.
21019 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21020 (timer_check_2): Mark vars as initialized.
21022 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21024 * image.c (lookup_image): Remove var that is set but not used.
21025 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21027 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21028 that are set but not used.
21030 * xfns.c (make_invisible_cursor): Don't return garbage
21031 if XCreateBitmapFromData fails (Bug#8410).
21033 * xselect.c (x_get_local_selection, x_handle_property_notify):
21034 Remove vars that are set but not used.
21036 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21037 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21039 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21040 Remove var that is set but not used.
21041 (scroll_bar_windows_size): Now size_t, not int.
21042 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21043 Check for overflow.
21045 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21046 (map_tty_color) [!defined MSDOS]: Likewise.
21048 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21050 * coding.c: Remove vars that are set but not used.
21051 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21052 All callers changed.
21053 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21054 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21055 (decode_coding_charset): Remove vars that are set but not used.
21057 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21058 that is set but not used.
21060 * print.c (print_object): Remove var that is set but not used.
21062 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21063 The gnulib version avoids calling malloc in the usual case,
21064 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21065 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21066 * filelock.c (current_lock_owner): Likewise.
21067 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21068 * sysdep.c: Include allocator.h, careadlinkat.h.
21069 (emacs_no_realloc_allocator): New static constant.
21070 (emacs_readlink): New function.
21071 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21072 ../lib/careadlinkat.h.
21074 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21076 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21077 first non-nil return value).
21079 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21081 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21082 if not defined (Bug#8403).
21084 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21086 * xdisp.c (display_count_lines): Remove parameter `start',
21087 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21088 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21089 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21091 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21092 and thereabouts. All callers changed.
21093 (get_per_char_metric): Remove parameter `f', unused since
21094 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21096 2011-04-02 Jim Meyering <meyering@redhat.com>
21098 do not dereference NULL upon failed strdup
21099 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21100 (ns_get_family): Likewise.
21102 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21104 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21106 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21108 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21111 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21113 Add lexical binding.
21115 * window.c (Ftemp_output_buffer_show): New fun.
21116 (Fsave_window_excursion):
21117 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21119 * lread.c (lisp_file_lexically_bound_p): New function.
21120 (Fload): Bind Qlexical_binding.
21121 (readevalloop): Remove `evalfun' arg.
21122 Bind Qinternal_interpreter_environment.
21123 (Feval_buffer): Bind Qlexical_binding.
21124 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21126 (syms_of_lread): Declare `lexical-binding'.
21128 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21130 * keyboard.c (eval_dyn): New fun.
21131 (menu_item_eval_property): Use it.
21133 * image.c (parse_image_spec): Use Ffunctionp.
21135 * fns.c (concat, mapcar1): Accept byte-code-functions.
21137 * eval.c (Fsetq): Handle lexical vars.
21138 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21139 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21140 (FletX, Flet): Obey lexical binding.
21141 (Fcommandp): Handle closures.
21142 (Feval): New `lexical' arg.
21143 (eval_sub): New function extracted from Feval. Use it almost
21144 everywhere where Feval was used. Look up vars in lexical env.
21146 (Ffunctionp): Move from subr.el.
21147 (Ffuncall): Handle closures.
21148 (apply_lambda): Remove `eval_flags'.
21149 (funcall_lambda): Handle closures and new byte-code-functions.
21150 (Fspecial_variable_p): New function.
21151 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21152 but without exporting it to Lisp.
21154 * doc.c (Fdocumentation, store_function_docstring):
21155 * data.c (Finteractive_form): Handle closures.
21157 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21160 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21162 (exec_byte_code): New function extracted from Fbyte_code to handle new
21163 calling convention for byte-code-functions. Add new byte-codes.
21165 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21167 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21169 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21171 * xdisp.c (redisplay_internal): Fix prototype.
21173 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21175 * xdisp.c (SCROLL_LIMIT): New macro.
21176 (try_scrolling): Use it when setting scroll_limit.
21177 Limit scrolling to 100 screen lines.
21178 (redisplay_window): Even when falling back on "recentering",
21179 position point in the window according to scroll-conservatively,
21180 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21182 (try_scrolling): When point is above the window, allow searching
21183 as far as scroll_max, or one screenful, to compute vertical
21184 distance from PT to the scroll margin position. This prevents
21185 try_scrolling from unnecessarily failing when
21186 scroll-conservatively is set to a value slightly larger than the
21187 window height. Clean up the case of PT below the margin at bottom
21188 of window: scroll_max can no longer be INT_MAX. When aggressive
21189 scrolling is in use, don't let point enter the opposite scroll
21190 margin as result of the scroll.
21191 (syms_of_xdisp) <scroll-conservatively>: Document the
21192 threshold of 100 lines for never-recentering scrolling.
21194 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21196 * dispextern.h (move_it_by_lines):
21197 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21198 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21199 (message_log_check_duplicate): Remove parameters `prev_bol' and
21200 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21201 (redisplay_internal): Remove parameter `preserve_echo_area',
21202 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21204 * indent.c (Fvertical_motion):
21205 * window.c (window_scroll_pixel_based, Frecenter):
21206 Don't pass `need_y_p' to `move_it_by_lines'.
21208 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21210 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21211 steal a few bits to be more compact.
21212 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21213 Remove unneeded casts.
21215 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21217 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21219 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21220 binding" message (bug#7967).
21222 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21224 Fix more problems found by GCC 4.6.0's static checks.
21226 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21227 Remove unused local var.
21229 * editfns.c (Fmessage_box): Remove unused local var.
21231 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21232 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21233 Omit unused local vars.
21234 * window.c (shrink_windows): Omit unused local var.
21235 * menu.c (digest_single_submenu): Omit unused local var.
21236 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21237 Omit unused local var.
21239 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21240 Don't assume string length fits in int.
21241 (keyremap_step, read_key_sequence): Use size_t for sizes.
21242 (read_key_sequence): Don't check last_real_key_start redundantly.
21244 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21245 instead of alloca (Bug#8344).
21247 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21248 (Fbacktrace_frame): Don't assume nframes fits in int.
21250 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21252 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21255 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21257 * cm.c (calccost): Turn while-do into do-while, for clarity.
21259 * keyboard.c (syms_of_keyboard): Use the same style as later
21260 in this function when indexing through an array. This also
21261 works around GCC bug 48267.
21263 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21265 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21267 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21268 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21270 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21271 This avoids undefined behavior on integer overflow, and is a bit
21272 more convenient anyway since it is compared to a size_t variable.
21274 Variadic C functions now count arguments with size_t, not int.
21275 This avoids an unnecessary limitation on 64-bit machines, which
21276 caused (substring ...) to crash on large vectors (Bug#8344).
21277 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21278 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21279 All variadic functions and their callers changed accordingly.

21285 (funcall_lambda, mark_backtrace): Likewise.
21286 * fns.c (concat): Likewise.
21287 * frame.c (x_set_frame_parameters): Likewise.
21288 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21289 0 if not found, not -1. All callers changed.
21291 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21292 (stack_copy_size): Now size_t, not int.
21293 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21295 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21297 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21298 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21498 * buffer.c (Fkill_all_local_variables):
21499 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21501 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21502 unconditionally since it does the check itself.
21504 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21506 Fix more problems found by GCC 4.5.2's static checks.
21508 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21509 the first time through the loop, since we know p0 < p1 then.
21510 This also avoids a gcc -Wstrict-overflow warning.
21512 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21513 leading to a memory leak, possible in functions like
21514 load_charset_map_from_file that can allocate an unbounded number
21515 of objects (Bug#8318).
21517 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21518 that could (at least in theory) be that large.
21520 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21521 This is less likely to overflow, and avoids undefined behavior if
21522 overflow does occur. All callers changed. Use strtoul to scan
21523 for the unsigned long integer.
21524 (pint2hrstr): Simplify and tune code slightly.
21525 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21540 * process.c (Fmake_network_process): Use socklen_t, not int,
21541 where POSIX says socklen_t is required in portable programs.
21542 This fixes a porting bug on hosts like 64-bit HP-UX, where
21543 socklen_t is wider than int (Bug#8277).
21544 (Fmake_network_process, server_accept_connection):
21545 (wait_reading_process_output, read_process_output):
21548 * process.c: Rename or move locals to avoid shadowing.

21558 Make tparam.h and terminfo.c consistent.
21559 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21560 Include tparam.h instead, since it declares them.
21561 * cm.h (PC): Remove extern decl; tparam.h now does this.
21562 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21563 * terminfo.c: Include tparam.h, to check interfaces.
21564 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21565 (tparam): Adjust signature to match interface in tparam.h;
21566 this removes some undefined behavior. Check that outstring and len
21567 are zero, which they always are with Emacs.
21568 * tparam.h (PC, BC, UP): New extern decls.
21570 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21571 (xftfont_open): Rename locals to avoid shadowing.

21589 (composition_update_it): Mark var as initialized.
21590 (find_automatic_composition): Mark vars as initialized,
21591 with a FIXME (Bug#8290).

21597 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21598 to avoid shadowing.

21610 Fix pointer signedness.
21611 (alsa_choose_format): Remove unused local var.
21612 (wav_play): Initialize a variable to 0, to prevent undefined
21613 behavior (Bug#8278).
21615 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21617 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21619 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21620 clobbering (Bug#8298).
21621 * sysdep.c (sys_subshell): Likewise.
21622 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21624 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21625 This should get cleaned up, so that child_setup has the
21626 same signature on all platforms.
21628 * callproc.c (call_process_cleanup): Now static.
21629 (relocate_fd): Rename locals to avoid shadowing.
21631 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21633 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21634 not to be necessary, and produces flickering.
21636 2011-03-20 Glenn Morris <rgm@gnu.org>
21638 * config.in: Remove file.
21640 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21685 Define only if needed.
21687 * unexelf.c (unexec): Name an expression,
21688 to avoid gcc -Wbad-function-cast warning.
21689 Use a different way to cause a compilation error if anyone uses
21690 n rather than nn, a way that does not involve shadowing.
21691 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21693 * deps.mk (unexalpha.o): Remove; unused.

21747 to avoid gcc -Wbad-function-cast warning.
21748 (Fdefvar): Rename locals to avoid shadowing.
21750 * callint.c (quotify_arg, quotify_args): Now static.
21751 (Fcall_interactively): Rename locals to avoid shadowing.
21752 Use const pointer when appropriate.
21754 * lisp.h (get_system_name, get_operating_system_release):

21758 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21759 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21760 some of which prompt warnings from gcc -Wbad-function-cast.
21761 (Fformat_time_string, Fencode_time, Finsert_char):
21762 (Ftranslate_region_internal, Fformat):
21763 Rename or remove local vars to avoid shadowing.

21789 (GC_STRING_CHARS): Remove; not used.
21790 (Fmemory_limit): Cast sbrk's returned value to char *.
21792 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21793 avoids undefined behavior in theory.
21795 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21797 Use functions, not macros, for up- and down-casing (Bug#8254).
21798 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21799 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21800 to use the following functions instead of these macros.
21801 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21802 EMACS_INT, since callers assume the returned value fits in int.
21803 (upcase1): Likewise, for UPCASE_TABLE.
21804 (uppercasep, lowercasep, upcase): New static inline functions.
21805 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21815 (regex_compile, re_match_2_internal): Mark locals as initialized.
21816 (RETALLOC_IF): Define only if needed.
21817 (WORDCHAR_P): Likewise. This one is never needed, but is used
21818 only in a comment talking about a compiler bug, so put inside
21819 the #if 0 of that comment.
21820 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21821 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21847 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21848 New macros, so that the caller can use some names other than
21849 gcpro1, gcpro2, etc.
21850 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21852 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21853 argument, for consistency with GCPRO2_VAR, etc: it is now the
21854 prefix of the variable, not the variable itself. All uses
21856 * dired.c (directory_files_internal, file_name_completion):
21857 Rename locals to avoid shadowing.
21859 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21860 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21861 dired.c's scmp function, had undefined behavior.
21862 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21863 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21864 * buffer.h: ... to here, because these macros use current_buffer,
21865 and the new implementation with inline functions needs to have
21866 current_buffer in scope now, rather than later when the macros
21868 (downcase, upcase1): New static inline functions.
21869 (DOWNCASE, UPCASE1): Reimplement using these functions.
21870 This avoids undefined behavior in expressions like
21871 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21872 from race conditions in accessing the global variables
21873 case_temp1 and case_temp2.
21874 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21875 * lisp.h (case_temp1, case_temp2): Remove their decls.
21876 * character.h (ASCII_CHAR_P): Move from here ...
21877 * lisp.h: ... to here, so that the inline functions mentioned
21878 above can use them.
21880 * dired.c (directory_files_internal_unwind): Now static.
21882 * fileio.c (file_name_as_directory, directory_file_name):
21883 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21885 (file_name_as_directory): Use const pointers when appropriate.
21886 (Fexpand_file_name): Likewise. In particular, newdir might
21887 point at constant storage, so make it a const pointer.
21888 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21889 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21891 (Fset_file_times, Finsert_file_contents, auto_save_error):

21896 to avoid shadowing.
21898 * marker.c (bytepos_to_charpos): Remove; unused.
21900 * lisp.h (verify_bytepos, count_markers): New decls,
21901 so that gcc does not warn that these functions aren't declared.
21903 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21904 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21905 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21906 (copy_text): Remove unused local var.
21908 * filelock.c (within_one_second): Now static.
21909 (lock_file_1): Rename local to avoid shadowing.
21911 * buffer.c (fix_overlays_before): Mark locals as initialized.
21912 (fix_start_end_in_overlays): Likewise. This function should be
21913 simplified by using pointers-to-pointers, but that's a different

21916 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21917 (report_overlay_modification): Rename locals to avoid shadowing.

21920 Fix pointer signedness issue.
21921 (sys_subshell): Mark local as volatile if checking for lint,
21922 to suppress a gcc -Wclobbered warning that does not seem to be right.
21923 (MAXPATHLEN): Define only if needed.
21925 * process.c (serial_open, serial_configure): Move decls from here ...
21926 * systty.h: ... to here, so that they can be checked.
21928 * fns.c (get_random, seed_random): Move extern decls from here ...
21929 * lisp.h: ... to here, so that they can be checked.
21931 * sysdep.c (reset_io): Now static.
21932 (wait_for_termination_signal): Remove; unused.

21940 (describe_map_tree):
21941 Rename locals to avoid shadowing.

22092 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22093 reports time overflow. See
