3 * keyboard.c (read_char): Fix calculation of auto-save time out
4 when auto-save-timeout is less than 4. (Bug#13720)
6 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
7 time. Improve diagnostics in DebPrint.
8 (reader_thread): If cp->char_avail is NULL, set the FILE_AT_EOF
9 flag, so that sys_select could have a chance of noticing that this
10 process is dead, and call a SIGCHLD handler for it. Improve
11 diagnostics in DebPrint.
12 (reap_subprocess): Reset the FILE_AT_EOF flag set by
14 (sys_select): Watch a process whose procinfo.hProcess is non-NULL
15 even if its char_avail is NULL. Allows to reap subprocesses that
16 were forcibly deleted by delete-process. (Bug#13546)
18 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
19 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
20 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
21 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
22 make sure errno is set to an appropriate value. (Bug#13546)
23 (socket_to_fd): Add assertion against indexing fd_info[] with a
24 value that is out of bounds.
25 (sys_accept): If fd is negative, do not set up the child_process
26 structure for reading.
28 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
30 * composite.c (fill_gstring_header): Remove useless prototype.
32 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
33 * print.c (PRINTDECLARE, print_object):
34 * search.c (compile_pattern, fast_looking_at, search_buffer):
35 (simple_search, boyer_moore, Freplace_match):
36 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
37 (get_overlay_arrow_glyph_row, display_mode_element):
38 (decode_mode_spec_coding, message3):
39 * xfaces.c (face_at_string_position): Use bool for booleans.
42 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
44 Fix AIX port (Bug#13650).
45 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
46 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
47 was #undeffed earlier, so it cannot be used as a macro here.
48 Use the constant and not the macro.
50 2013-02-15 Eli Zaretskii <eliz@gnu.org>
52 * w32proc.c (new_child): If no vacant slots are found in
53 child_procs[], make another pass looking for slots whose process
54 has exited or died. (Bug#13546)
56 * w32.c (sys_pipe): When failing due to file descriptors above
57 MAXDESC, set errno to EMFILE.
58 (_sys_read_ahead): Update cp->status when failing to read serial
59 communications input, so that the status doesn't stay at
60 STATUS_READ_IN_PROGRESS. (Bug#13546)
62 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
64 * gtkutil.c (tb_size_cb): New function.
65 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
67 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
69 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
72 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
74 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
76 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
78 * font.c (font_range): Add pos_byte argument. Adjust comment
80 * font.h (font_range): Adjust prototype.
81 * composite.c (autocmp_chars): Pass byte position to font_range.
82 Break long line. Remove useless prototype and format comment.
84 2013-02-13 Glenn Morris <rgm@gnu.org>
86 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
88 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
90 Improve AIX port some more (Bug#13650).
91 With this, it should be as good as it was in 23.3, though it's
92 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
93 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
94 * unexaix.c (start_of_text): Remove.
95 (_data, _text): Declare as char[], not int, as AIX manual suggests.
96 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
97 (orig_load_scnptr, orig_data_scnptr):
98 Now off_t, not long, since they are file offsets.
99 (make_hdr): Use _data, not start_of_data ().
100 This is the key part of the fix.
101 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
102 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
104 * pre-crt0.c (data_start): Initialize to 1.
105 This ports to compilers that optimize the external declaration
106 'int x = 0;' as if it were 'int x;' to shrink the executable.
108 Improve AIX port (Bug#13650).
109 This doesn't fix the bug, but it makes progress: Emacs builds now.
110 * unexaix.c: Include inttypes.h, stdarg.h.
111 (report_error, report_error_1): Mark as _Noreturn.
112 (report_error): Don't report the wrong errno.
113 (report_error_1): Now varargs. All callers changed.
114 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
115 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
116 (write_ptr): Use %p to print address rather than %lx and a cast
117 to unsigned long. Grow buffer a bit, to be safer.
119 2013-02-13 Eli Zaretskii <eliz@gnu.org>
121 * bidi.c (bidi_resolve_neutral): After finding the next
122 non-neutral character, accept NEUTRAL_ON type as well, because
123 directional control characters, such as LRE and RLE, have their
124 type converted to that by bidi_resolve_weak. This avoids aborts
125 when LRE/RLE follows a run of neutrals.
126 (bidi_move_to_visually_next): Assert that return value of
127 bidi_peek_at_next_level is non-negative. Negative values will
130 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
132 Minor getenv-related fixes.
133 * callproc.c (Fcall_process_region) [!DOS_NT]:
134 Avoid unnecessary duplicate call to getenv.
135 * callproc.c (init_callproc):
136 * dispnew.c (init_display):
137 * sysdep.c (sys_subshell):
138 Omit unnecessary cast of getenv or egetenv.
140 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
142 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
145 2013-02-12 Eli Zaretskii <eliz@gnu.org>
147 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
149 (display_line): Set w->region_showing to the value of
150 it->region_beg_charpos, not to -1. This fixes redisplay
151 optimization when cursor is moved up after M->. (Bug#13623)
153 (try_scrolling): Scroll text up more if point is too close to ZV
154 and inside the scroll margin. This makes sure point is moved
155 outside the scroll margin in these cases.
157 * window.h (struct window): region_showing can no longer be
160 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
162 Tune by using memchr and memrchr.
163 * doc.c (Fsnarf_documentation):
164 * fileio.c (Fsubstitute_in_file_name):
165 * search.c (find_newline, scan_newline):
166 * xdisp.c (pos_visible_p, display_count_lines):
167 Use memchr and memrchr rather than scanning byte-by-byte.
168 * search.c (find_newline): Rename from scan_buffer.
169 Omit first arg TARGET, as it's always '\n'. All callers changed.
171 Clean up read_key_sequence a tiny bit more.
172 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
173 (read_key_sequence): Remove unused locals.
175 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
177 Clean up read_key_sequence a bit; reread active keymaps after first event.
178 * keyboard.c (read_char, read_char_x_menu_prompt)
179 (read_char_minibuf_menu_prompt):
180 Replace nmaps+maps with a single `map' arg.
181 (follow_key): Operate on a single map.
182 (active_maps): New function.
183 (test_undefined): Also return true for nil bindings.
184 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
185 a single (composed) keymap. Remember `first_event' to choose the right
186 set of active keymaps. Recompute the set of keymaps after receiving
187 the first event. Remove GOBBLE_FIRST_EVENT.
188 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
189 * keyboard.h (read_char): Update declaration.
190 * lread.c (read_filtered_event): Adjust call to read_char.
192 2013-02-11 Eli Zaretskii <eliz@gnu.org>
194 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
195 Don't use the limitation on backwards movement when lines are truncated
196 in the window. (Bug#13675)
198 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
200 * marker.c (set_marker_internal): If desired position is passed
201 as a marker, avoid call to buf_charpos_to_bytepos.
202 * window.c (Fset_window_point): Omit redundant type checking.
203 (Fset_window_start): Likewise. Format comment.
204 (window_scroll_pixel_based): Use set_marker_restricted_both
205 with character and byte positions obtained from an iterator.
206 (Fset_window_configuration): Use set_marker_restricted_both.
207 * xdisp.c (message_dolog): Likewise.
209 2013-02-10 Eli Zaretskii <eliz@gnu.org>
211 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
212 When text lines are longer than window's screen lines, don't move back
213 too far. This speeds up some redisplay operations. (Bug#13675)
215 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
217 * syntax.c (scan_sexps_forward): Fix byte position calculation
218 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
220 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
222 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
225 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
227 Minor hashing refactoring.
228 * fns.c (SXHASH_REDUCE): Move to lisp.h.
229 (sxhash_float): Return EMACS_UINT, for consistency with the other
231 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
232 non-static inline function and therefore can't use static vars.
233 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
234 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
235 with the other hash functions.
237 2013-02-09 Eli Zaretskii <eliz@gnu.org>
239 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
240 XXXXXX part of the temporary file pattern is not downcased even
241 when w32-downcase-file-names is non-nil. (Bug#13661)
243 * xdisp.c (decode_mode_spec): Remove handling of %t.
245 * msdos.c (careadlinkatcwd): Remove.
247 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
249 * lread.c (skip_dyn_bytes): New function (bug#12598).
250 (read1): Use it. Use getc instead of READCHAR to read bytes.
251 (load_each_byte): Remove. Update users.
253 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
255 * search.c (scan_buffer): Calculate end byte position just once.
256 (scan_newline): Do not recalculate start_byte.
257 (search_command): Use eassert.
258 * syntax.c (struct lisp_parse_state): New member location_byte.
259 (scan_sexps_forward): Record from_byte and avoid redundant
260 character to byte position calculation ...
261 (Fparse_partial_sexp): ... here. Break too long line.
263 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
265 * lisp.h (make_uninit_vector): New function.
266 * alloc.c (Fvector, Fmake_byte_code):
267 * ccl.c (Fregister_ccl_program):
268 * charset.c (Fdefine_charset_internal, define_charset_internal):
269 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):
270 * composite.c (syms_of_composite):
271 * font.c (Fquery_font, Ffont_info, syms_of_font):
272 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
273 * ftfont.c (ftfont_shape_by_flt):
274 * indent.c (recompute_width_table):
275 * nsselect.m (clean_local_selection_data):
276 * syntax.c (init_syntax_once):
277 * w32unsubscribe.c (uniscribe_shape):
278 * window.c (Fcurrent_window_configuration):
279 * xfaces.c (Fx_family_fonts):
280 * xselect.c (selection_data_to_lisp_data): Use it.
282 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
284 * coding.c (Fdefine_coding_system_internal): Use AREF where
285 argument is known to be a vector.
286 * fns.c (Flocale_info): Likewise for ASET.
287 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
288 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
290 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
292 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
295 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
296 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
297 updateCollectionBehaviour.
299 * nsterm.m (NEW_STYLE_FS): Remove.
300 (ns_last_use_native_fullscreen): New variable.
301 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
302 (x_set_window_size): Do not take title bar and tool bar into account
303 if isFullscreen returns YES.
304 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
305 (check_native_fs): New function.
306 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
307 (ns_term_init): Remove NEW_STYLE_FS.
308 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
309 and tool bar if isFullscreen returns NO.
310 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
311 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
313 (window:willUseFullScreenPresentationOptions:): New method.
314 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
315 Hide toolbar if not enabled (Bug#13444).
316 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
317 Restore tool bar if enabled, hide it otherwise (Bug#13444).
318 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
319 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
320 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
321 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
322 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
323 (syms_of_nsterm): Add ns-use-native-fullscreen.
325 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
327 * fileio.c (Qchoose_write_coding_system): Now static.
329 2013-02-04 Eli Zaretskii <eliz@gnu.org>
331 * xdisp.c (window_buffer_changed): region_showing can be negative,
332 which still means region is being displayed.
333 (redisplay_internal): Resurrect code that forced redisplay of the
334 whole window when showing region and the mark has changed.
335 Record the new mark position to allow redisplay optimizations.
336 (display_line): If it->region_beg_charpos is non-zero, set the
337 window's region_showing member to -1. (Bug#13623) (Bug#13626)
339 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
340 not bitfield of 1 bit.
342 2013-02-03 Daniel Colascione <dancol@dancol.org>
344 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
345 daemon mode works on cygw32 when Emacs is installed and not just
348 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
350 Avoid file time stamp bug on MS-Windows (Bug#13149).
351 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
352 as FAT32 doesn't update time stamps when truncating them.
353 Also, check that a file time stamp is not a multiple of 100 ns;
354 this should catch all instances of the problem on MS-Windows,
355 as its native file system resolution is 100 ns or worse, and
356 checking for a non-multiple of 100 ns should impose only a small
357 overhead on systems with ns resolution.
359 2013-02-02 Eli Zaretskii <eliz@gnu.org>
361 Avoid encoding file names on MS-Windows when they need to be run
362 through dostounix_filename.
363 * w32.c (normalize_filename): Accept an additional argument
364 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
365 downcase it even if w32-downcase-file-names is non-nil.
366 (dostounix_filename): Accept an additional argument MULTIBYTE and
367 pass it to normalize_filename.
368 (emacs_root_dir): Adjust.
370 * msdos.h (dostounix_filename): Adjust prototype.
372 * w32.h (dostounix_filename): Adjust prototype.
374 * msdos.c (dostounix_filename): Accept an additional argument and
376 (init_environment): Adjust callers of dostounix_filename.
378 * fileio.c (Ffile_name_directory, file_name_as_directory)
379 (directory_file_name, Fexpand_file_name)
380 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
382 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
384 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
385 variables, as egetenv is case-insensitive for DOS_NT.
387 * dired.c (file_name_completion): Don't call Fdirectory_file_name
388 with an encoded file name.
390 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
391 Adjust calls to dostounix_filename.
393 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
395 * unexw32.c (unexec): Adjust call to dostounix_filename.
397 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
399 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
402 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
405 * callproc.c (Fcall_process): Make sure program name in PATH and
406 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
407 is passed to exec/spawnve, which fails unless the file-name
410 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
411 even if w32-quote-process-args is nil.
413 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
415 Fix timestamp bug when write-region appends nothing (Bug#13149).
416 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
417 the file's time stamp doesn't change if Emacs happens to write nothing
418 to the file, and on a buggy file system this could cause Emacs to
419 incorrectly infer that the file system doesn't have the bug.
420 Avoid this problem by inhibiting the inference in this case.
422 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
424 * window.h (struct window): Convert base_line_number, base_line_pos
425 and column_number_displayed members from Lisp_Object to ptrdiff_t.
426 Convert region_showing member from Lisp_Object to bitfield.
427 Remove sequence_number member. Adjust comments.
428 * window.c (sequence_number): Remove.
429 (make_window): Initialize column_number_displayed.
430 * print.c (print_object): Follow the printed representation of
431 frames and print window pointer to distinguish between windows.
432 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
433 * xdisp.c (wset_base_line_number, wset_base_line_pos)
434 (wset_column_number_displayed, wset_region_showing): Remove.
435 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
436 (try_scrolling, try_cursor_movement, redisplay_window)
437 (try_window_reusing_current_matrix, try_window_id, display_line)
438 (display_mode_lines, decode_mode_spec): Adjust users.
439 * .gdbinit (pwinx): Do not print sequence_number.
441 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
443 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
444 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
445 * dired.c: Include <fcntl.h>.
446 (open_directory): New function, which uses open and fdopendir
447 rather than opendir. DOS_NT platforms still use opendir, though.
448 (directory_files_internal, file_name_completion): Use it.
449 (file_attributes): New function, with most of the old Ffile_attributes.
450 (directory_files_internal, Ffile_attributes): Use it.
451 (file_attributes, file_name_completion_stat): First arg is now fd,
452 not dir name. All uses changed. Use fstatat rather than lstat +
454 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
455 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
456 (emacs_readlinkat): New function, with much of the old
457 Ffile_symlink_p, but with an fd argument for speed.
458 It uses readlinkat rather than careadlinkatcwd, so that it
459 need not assume the working directory.
460 (Ffile_symlink_p): Use it.
461 * filelock.c (current_lock_owner): Use emacs_readlinkat
462 rather than emacs_readlink.
463 * lisp.h (emacs_readlinkat): New decl.
464 (READLINK_BUFSIZE, emacs_readlink): Remove.
465 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
466 (emacs_norealloc_allocator, emacs_readlink): Remove.
467 This stuff is moved to fileio.c.
468 * w32.c (fstatat, readlinkat): New functions.
469 (careadlinkat): Don't check that fd == AT_FDCWD.
470 (careadlinkatcwd): Remove; no longer needed.
472 2013-01-31 Glenn Morris <rgm@gnu.org>
474 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
475 (Fwrite_region): Update for new choose_write_coding_system args.
476 Move the last piece of choose_write_coding_system here. (Bug#13522)
477 (syms_of_fileio): Add choose-write-coding-system.
479 2013-01-30 Eli Zaretskii <eliz@gnu.org>
481 * w32.c (sys_open): Zero out the flags for the new file descriptor.
482 (sys_close): Zero out the flags for the file descriptor before
483 closing it. (Bug#13546)
485 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
486 (logon_network_drive, stat_worker, symlink, chase_symlinks):
487 Use CharNextExA and CharPrevExA to iterate over file names encoded in
490 * w32.c (w32_get_long_filename, init_environment, readlink):
491 Support file names encoded in DBCS codepages.
492 (readlink): Use the current file-name-coding-system, not the ANSI
493 codepage, to decode and handle targets of symlinks.
495 2013-01-28 Eli Zaretskii <eliz@gnu.org>
497 * w32.c (opendir): Now accepts a 'const char *'.
499 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
501 Remove obsolete redisplay code. See the discussion at
502 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
503 * dispnew.c (preemption_period, preemption_next_check): Remove.
504 (Vredisplay_preemption_period): Likewise.
505 (update_frame, update_single_window, update_window, update_frame_1):
506 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
507 used, following the 2012-06-22 change.
509 2013-01-25 Eli Zaretskii <eliz@gnu.org>
511 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
513 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

523 * w32.c (max_filename_mbslen): New function.
524 (normalize_filename, readdir): Use it to detect locales where ANSI
525 encoding of file names uses a double-byte character set (DBCS).
526 If a DBCS encoding is used, advance by characters using
527 CharNextExA, instead of incrementing a 'char *' pointer.
528 Use _mbslwr instead of _strlwr. (Bug#13515)
530 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
531 request of memory reservation to 1.7GB. (Bug#13065)
533 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
535 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
536 at check_extra_latin label. (Bug#13505)
538 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
540 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
541 Avoid redundant calls to strlen.
543 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
545 Drop async_visible and async_iconified fields of struct frame.
546 This is possible because async input is gone; for details, see
547 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
548 * frame.h (struct frame): Remove async_visible and async_iconified
549 members, convert garbaged to unsigned bitfield. Adjust comments.
550 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
551 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
552 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
553 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
554 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
556 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
557 properly. Likewise for obscured.
559 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
562 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
564 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
566 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
567 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
569 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
571 * xdisp.c (message2, message2_nolog): Remove functions.
572 (message3, message3_nolog): Extract nbytes and multibyteness directly
573 from the string. Change all callers.
574 (message3_nolog): Don't set message_enable_multibyte since set_message
575 will reset it anyway.
576 (message1, message1_nolog): Use message3.
577 (vmessage): Use a stack allocated buffer rather than f->message_buf.
578 (with_echo_area_buffer): Remove last two arguments. Update all callers.
579 (set_message): Drop all but the second arg, which has to be a string.
580 (set_message_1): Simplify now that we know that a1 is NULL and the
581 second arg is a string.
582 * frame.h (struct frame): Remove `message_buf' field.
583 Use glyphs_initialized_p instead.
584 (FRAME_MESSAGE_BUF): Remove macro.
585 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
586 * lisp.h (message2, message2_nolog): Remove declarations.
587 (message3, message3_nolog): Update declarations.
588 * keyboard.c (read_char_minibuf_menu_text)
589 (read_char_minibuf_menu_width): Remove vars.
590 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
591 to correctly handle multibyte strings.
592 * frame.c (delete_frame): Don't free message_buf any more.
593 * editfns.c (message_text, message_length): Remove vars.
594 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
595 * fileio.c (auto_save_error): Use message3 instead of message2.
596 * dispnew.c (adjust_frame_message_buffer): Remove function.
598 2013-01-23 Eli Zaretskii <eliz@gnu.org>
600 * w32term.c (w32fullscreen_hook): Account correctly for the screen
601 real estate used for the tool bar and the menu bar.
603 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
605 * insdel.c (prepare_to_modify_buffer): Force redisplay if
606 hidden buffer is prepared to modification (Bug#13164).
608 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
610 * window.h (struct window): Change window_end_valid member from
611 Lisp_Object to a bitfield. Adjust comments.
612 (wset_window_end_valid): Remove.
613 * window.c (adjust_window_count): Clear window_end_valid.
614 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
615 (Fwindow_line_height, set_window_buffer, Frecenter)
616 (Fsplit_window_internal, Fdelete_other_windows_internal)
617 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
618 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
619 * xdisp.c (check_window_end, reconsider_clip_changes)
620 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
621 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
622 (find_first_unchanged_at_end_row, try_window_id): Likewise.
624 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
626 * xdisp.c (mark_window_display_accurate): Simplify the loop
627 assuming that the only one of vchild, hchild or buffer window
628 slots is non-nil. Call mark_window_display_accurate_1 for
629 the leaf windows only.
630 (mark_window_display_accurate_1): Always assume leaf window.
633 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
635 * emacs.c (Qkill_emacs_hook): Now static.
637 * fileio.c (Finsert_file_contents): Simplify.
638 Remove unnecessary assignments and tests.
640 2013-01-21 Eli Zaretskii <eliz@gnu.org>
642 * w32.c (acl_set_file): Don't test for errors unless
643 set_file_security returns FALSE. Avoids spurious errors when
646 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
648 * fileio.c (Finsert_file_contents): Revert code introduced at
649 2013-01-18 in favor of the simpler and generally better fix.
650 Save stack space by removing 'buffer' and reusing 'read_buf'
653 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
655 * lisp.h (eabs): Define unconditionally (Bug#13419).
656 The old "#if !defined (eabs)" was an unnecessary revenant of back
657 when this macro was called "abs". Document 'eabs' better.
659 2013-01-19 Glenn Morris <rgm@gnu.org>
661 * fns.c (Frandom): Doc fix.
663 2013-01-19 Eli Zaretskii <eliz@gnu.org>
665 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
666 segfault when there are lots of overlays.
668 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
669 when there are lots of overlays.
670 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
671 for the details and a way to reproduce.
673 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
675 * fileio.c: Use O_APPEND to append.
676 This corresponds better to the natural interpretation of "append",
677 and avoids the need to open the output file twice, or to invoke
678 lseek when APPEND is neither nil nor a number.
679 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
680 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
681 file possibly twice, and lseeking to its end; this avoids the
682 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
683 at the same time: the combination is never needed and apparently
684 it doesn't work with DOS_NT.
686 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
687 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
689 Allow floating-point file offsets.
690 Problem reported by Vitalie Spinu in
691 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
692 * fileio.c (emacs_lseek): Remove.
693 (file_offset): New function.
694 (Finsert_file_contents, Fwrite_region): Use it.
696 2013-01-19 Chong Yidong <cyd@gnu.org>
698 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
699 aborting on Fsignal (Bug#13289).
701 2013-01-19 Eli Zaretskii <eliz@gnu.org>
703 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
704 set_file_security as failure due to insufficient privileges.
705 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
706 (fstat): Return owner and group like 'stat' and 'lstat' do.
708 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
710 Work around bug in CIFS and vboxsf file systems (Bug#13149).
711 The bug was observed on Ubuntu operating inside a virtual machine,
712 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
713 The workaround introduces a race condition on non-buggy hosts,
714 but it's an unlikely race and anyway there's a nearly identical
715 nearby race that can't be fixed.
716 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
718 (Fwrite_region): Test for file system time stamp bug.
719 (init_fileio): New function.
720 * lisp.h (init_fileio): Declare it.
721 * emacs.c (main): Call it.
723 * fileio.c (Finsert_file_contents): Simplify new diagnostic
724 and make it more consistent with other stat-failure diagnostics.
726 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
728 Fix crash when inserting data from non-regular files.
729 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
730 for the error description produced by valgrind.
731 * fileio.c (read_non_regular): Rename to read_contents.
732 Free Lisp_Save_Value object used to pass parameters.
733 (read_non_regular_quit): Rename to read_contents_quit.
734 (Finsert_file_contents): Redesign internal file reading loop to adjust
735 gap and end positions after each read and so help make_gap to work
736 properly. Do not signal an I/O error too early and so do not leave
737 not yet decoded characters in a buffer, which was the reason of
738 redisplay crash. Use list2 to build return value. Adjust comments.
740 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
742 Close a race when statting and reading files (Bug#13149).
743 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
744 This avoids a race if the file is renamed between stat and open.
745 This race is not the problem originally noted in Bug#13149;
746 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
748 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

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

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

807 * editfns.c (save_excursion_save): Use format_save_value.
808 (save_excursion_restore): Use XSAVE_OBJECT.
810 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
812 Avoid needless casts with XSAVE_POINTER.
813 * alloc.c (mark_object) [GC_MARK_STACK]:
814 * dired.c (directory_files_internal_unwind):
815 * fileio.c (do_auto_save_unwind):
816 * gtkutil.c (pop_down_dialog):
817 * keymap.c (map_keymap_char_table_item):
818 * lread.c (load_unwind):
819 * nsmenu.m (pop_down_menu):
820 * print.c (print_object) [GC_MARK_STACK]:
821 * xfns.c (clean_up_file_dialog):
822 * xmenu.c (cleanup_widget_value_tree):
823 Omit casts between XSAVE_POINTER and a pointer type.
825 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
827 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
828 * eval.c (eval_sub): Protect `form' from being GCed before its
829 car and cdr becomes protected with the backtrace entry.
831 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
833 Make Lisp_Save_Value more versatile storage for up to four objects.
834 * lisp.h (toplevel): Enumeration to describe types of saved objects.
835 (struct Lisp_Save_Value): New layout. Adjust comments.

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

862 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
864 Fix SIGDANGER handlers, for AIX (Bug#13408).
865 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
866 Move handlers here from emacs.c; they were out of place.
868 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
870 * xterm.c (syms_of_xterm): Adjust documentation for
871 scroll-bar-adjust-thumb-portion.
873 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
875 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
876 determine whether scroll bar thumb size should be adjusted or
877 not. Use variable for MOTIF.
879 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
882 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

891 (nsfont_open): Move block_input earlier. Add unblock_input before early
893 (nsfont_draw): Add block/unblock_input calls.
895 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
897 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
898 for old_charpos and old_bytepos.
900 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>

903 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
904 Clear tzvalbuf_in_environ if this workaround is in effect.
905 Problem and fix reported by Kazuhiro Ito.
907 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
909 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):
910 Fix ambiguous doc string cross-reference(s).
912 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
913 doc string cross-reference(s).
915 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
916 string cross-reference(s).
918 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
920 Avoid unnecessary byte position calculation for the gap movement.
921 Since all users of move_gap do CHAR_TO_BYTE for other purposes
922 anyway, all of them should use move_gap_both instead.
923 * lisp.h (move_gap): Remove prototype.
924 * insdel.c (move_gap): Remove.
925 (move_gap_both): Add eassert.
926 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
927 * xml.c (parse_region): Likewise.
929 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
931 emacsclient -t should not suspend Emacs server (Bug#13387)
932 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
934 * term.c (init_tty): Use them instead of rolling our own code.
935 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
936 switches from 'signal' to 'pthread_sigmask', which is safer in
937 multithreaded applications.
938 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
939 which has already arranged for that.
940 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
941 This is the main part of the bug fix.
943 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
945 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around

1017 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1018 Display the newline glyph more unambiguously.
1020 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1022 * nsterm.m (ns_draw_underwave):
1023 * w32term.c (w32_draw_underwave):
1024 * xterm.c (x_draw_underwave): Make underwave look more triangular
1025 and also degrade gracefully for small fonts. (Bug#13000)
1027 * nsterm.m (ns_draw_text_decoration):
1028 * w32term.c (x_draw_glyph_string):
1029 * xterm.c (x_draw_glyph_string): Don't use previous underline

1056 * w32.c (unsetenv): Set up the string passed to _putenv
1058 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1059 for the bug this caused.
1061 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1063 * coding.c (Qmac): Now static.
1065 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1067 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.

1083 (xg_update_menubar): Update title only if
1084 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1085 (xg_update_submenu): Skip tearoff only if
1086 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1087 (xg_initialize): Initialize xg_detached_menus only if
1088 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1090 * xterm.h (struct x_output): Surround handlebox_widget with
1091 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

1117 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1119 Port EXTERNALLY_VISIBLE to Clang 3.2.
1120 * conf_post.h (__has_attribute): New macro.
1121 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1123 2012-12-27 Glenn Morris <rgm@gnu.org>
1125 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1126 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1128 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1130 * fileio.c (file_name_as_directory, directory_file_name):
1131 Accept an additional argument MULTIBYTE to indicate whether the input C
1132 came from a multibyte or a unibyte Lisp string; all callers
1133 adjusted. Don't assume the input string is always multibyte.
1135 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1136 don't ENCODE_FILE them, and return a unibyte string if the input
1138 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1139 don't assume the input strings will always be multibyte. If the
1140 input strings are multibyte, decode strings obtained from C
1143 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1145 * lisp.h (toplevel): Add two notices to the comment about

1152 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1154 * keyboard.c (record_asynch_buffer_change): Initialize an event
1155 only if it's really needed.
1156 * frame.h (enum output_method): Remove output_mac member since
1157 it's a leftover from the deleted code.
1158 * frame.c (Fframep): Adjust user here ...
1159 * terminal.c (Fterminal_live_p): ... and here.
1160 * coding.c (Qmac): Now here because it's only used to denote
1161 end-of-line encoding type.
1162 (syms_of_coding): DEFSYM it.
1163 * frame.h (Qmac): Remove duplicated declaration.
1165 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1167 * window.c (select_window_1): Now static, since it's used only here.
1169 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1171 * window.c (window_body_cols): Subtract display margins from the
1172 window body width on TTYs as well. See
1173 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1174 for the original report.
1176 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1178 * xdisp.c (redisplay_window): Remove inner local variable
1179 because the outer shadowed one has the same meaning.
1180 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1182 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1183 (xg_create_tool_bar): Adjust users.
1185 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1187 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1188 * buffer.c (Fget_buffer_create): Use it to set compact field of
1189 struct buffer_text to avoid accessing an uninitialized value
1190 when compact_buffer is called for the first time.
1191 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1192 (Fset_buffer_modified_p): Use buffer_window_count to check
1193 whether the buffer is displayed in some window.
1194 * xdisp.c (message_dolog): Likewise.
1196 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1198 * w32.c (acl_set_file): If setting the file security descriptor
1199 fails, and the new DACL is identical to the existing one, silently
1200 return success. This fixes problems for users backing up their
1201 own files without having the necessary privileges for setting
1202 security descriptors.
1204 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1206 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1207 after WaitForSingleObject returns normally. This expedites reader
1208 thread shutdown when delete_child triggers it.
1209 (reap_subprocess): More accurate commentary for why we call
1210 delete_child only when cp->fd is negative.
1212 * w32.c (sys_close): Do not call delete_child on a subprocess
1213 whose handle is not yet closed. Instead, set its file descriptor
1214 to a negative value, so that reap_subprocess will call
1215 delete_child on that subprocess when its SIGCHLD arrives.
1216 This avoids closing handles used for communications between sys_select
1217 and reader_thread, which doesn't give sys_select a chance to
1218 notice that the process exited and invoke the SIGCHLD handler for
1221 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1223 * nsfns.m (Fns_do_applescript): Run event loop until script has
1224 been executed (Bug#12969).
1225 (ns_run_ascript): Chech as_script for nil, set to nil after
1228 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1230 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1232 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1234 * w32term.c (w32fullscreen_hook): New function.
1235 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1237 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1239 * fileio.c (Finsert_file_contents): Doc fix.
1241 * w32proc.c (new_child, delete_child, find_child_pid): For a
1242 subprocess, consider its slot being in use as long as its process
1243 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1244 slot when a new process is started immediately after killing
1245 another one, without waiting enough time for the first process to
1246 be reaped and resources allocated for it be orderly freed.
1248 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1250 2012-12-21 Chong Yidong <cyd@gnu.org>
1252 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1254 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1256 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1258 * w32.c (get_name_and_id): Always pass NULL as the first argument
1259 of lookup_account_sid. Avoids crashes with UNC file names that
1260 refer to DFS domains, not to specific machine names. (Bug#12621)
1261 Remove now unused argument FNAME; all callers changed.
1262 (get_file_owner_and_group): Remove now unused argument FNAME; all
1265 2012-12-21 Chong Yidong <cyd@gnu.org>
1267 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1268 error for invalid chars, don't check for a nil return value.
1270 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1272 Avoid calls to CHAR_TO_BYTE if byte position is known.
1273 * editfns.c (make_buffer_string_both): Use move_gap_both.
1274 (Fbuffer_string): Use make_buffer_string_both.
1275 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1277 (buf_bytepos_to_charpos): Likewise.
1278 (charpos_to_bytepos): Remove.
1279 * fileio.c (Finsert_file_contents): Use move_gap_both.
1280 * search.c (Freplace_match): Likewise.
1281 * process.c (process_send_region): Likewise. Use convenient
1282 names for byte positions.
1283 * lisp.h (charpos_to_bytepos): Remove prototype.
1284 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1285 * insdel.c (move_gap): Likewise.

1291 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1293 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1294 (redisplay_internal): Don't bother selecting the frame to get the
1295 proper value of frame-local variables (bug#13225).
1297 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1299 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1300 Rename 4th argument since it may be buffer or string. Adjust comment.
1301 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1303 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1305 * coding.c (Fdetect_coding_region): Do not check start and end with
1306 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1307 (code_convert_region): Likewise.
1309 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1311 * w32.c (acl_get_file, acl_set_file): Run the file name through
1312 map_w32_filename, and resolve any symlinks in the file name, like
1314 (acl_set_file): Call revert_to_self, if any privileges were

1320 ($(BLD)/w32.$(O)): Update dependencies.
1322 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1324 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1325 propagate redisplay's scrolling (if any) to the right window.
1326 (redisplay_internal): Use ensure_selected_frame.
1327 (display_mode_lines): Complete last fix.
1328 * window.c (select_window_1): New func, extracted from select_window.
1329 (select_window): Use it.
1330 * window.h (select_window_1): Declare.

1356 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1358 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1359 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1360 for some of that bug's symptoms can now cause Emacs to abort.
1361 Remove the workaround.
1362 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1363 The bug that caused SIGCHLD to get lost has been fixed, and the
1364 workaround for it can now cause Emacs to abort.
1366 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1368 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1369 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1370 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1425 Fix permissions bugs with setgid directories etc. (Bug#13125)
1426 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1427 to mark it as a placeholder. The old value was often wrong.
1428 The only user of this attribute has been changed to use
1429 file-ownership-preserved-p instead, with its new group arg.
1430 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1432 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
1434 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
1435 Keep selected_window and selected_frame in sync.
1437 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1439 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1440 try to get accurate owner and group information from NT file
1441 security APIs. This is to make most callers of 'stat' and
1442 'lstat', which don't need that information, much faster.
1444 * dired.c (Ffile_attributes) [WINDOWSNT]:
1445 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1446 owner and group information from 'lstat'.
1448 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1450 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1451 as that confuses set-auto-coding, so insist on the head-read
1452 returning the full 1024 bytes. Let lseek compute the tail offset;
1453 less work for us. Do not ignore I/O errors when reading the tail.
1455 * xdisp.c: Minor style fixes.
1456 (init_iterator): Hoist assignment out of if-expression.
1457 (markpos_of_region): Callers now test for sign, not for -1.
1459 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
1461 Minor redisplay optimization when the region length is zero.
1462 * xdisp.c (markpos_of_region): New function.
1463 (init_iterator): Do not highlight the region of zero length.
1464 (redisplay_window): Check whether the region is of non-zero length.

1474 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1476 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1477 files, fixing a regression from 24.2.
1478 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1480 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1482 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1483 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1484 Remove unnecessary S_ISLNK test, as (contra the comments) this
1485 function can't copy symlinks. Improve quality of error message
1486 when attempting to copy files that are neither regular files nor

1495 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1497 2012-12-12 Daniel Colascione <dancol@dancol.org>
1499 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1500 the dumped Emacs is not a sparse file, greatly improving Cygwin
1501 "make bootstrap" performance.
1503 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1505 * inotify.c (inotify_callback): Generate an Emacs event for every
1506 incoming inotify event.
1508 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1510 * xdisp.c (handle_face_prop): Fix logic of computing
1511 it->start_of_box_run_p.
1512 (append_space_for_newline): If the glyph row is R2L, reset the
1513 iterator's end_of_box_run_p flag before prepending the space glyph.
1514 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1515 iterator's start_of_box_run_p flag before prepending the stretch.
1516 (append_glyph, produce_image_glyph, append_composite_glyph)
1517 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1518 left_box_line_p and right_box_line_p flags of the glyph for R2L
1519 glyph rows. (Bug#13011)
1521 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1523 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
1524 if changed buffer is not shown in a window.
1525 * insdel.c (prepare_to_modify_buffer): Likewise.
1526 * window.c (replace_buffer_in_windows_safely): Do nothing
1527 if buffer is not shown in a window.
1528 (Fforce_window_update): Likewise if string or buffer argument
1531 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1533 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1534 encoded_file_name, which is what it is.
1536 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1538 Consistently use marker_position and marker_byte_position.
1539 * fringe.c (Ffringe_bitmaps_at_pos):
1540 * indent.c (Fvertical_motion):
1541 * insdel.c (prepare_to_modify_buffer):

1560 Windows file notification functionality unless WINDOWSNT.
1562 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1565 * w32fns.c (cache_system_info): Initialize the global hinst
1566 variable here so various initialization calls DTRT.
1568 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1569 (hinst): Remove unneeded extern declaration.
1570 (_start): Remove initialization of above variables; remove
1571 initialization of hinst, as cache_system_info now does that.
1573 * emacs.c (main): Call cache_system_info early in startup; we
1574 previously weren't calling it in Cygwin builds.
1576 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
1577 Teach the autoconf build system how to compile a Windows resource file
1578 and link it to Emacs.

1609 indication whether any WM_EMACS_FILENOTIFY messages were found in
1612 * w32inevt.c (handle_file_notifications): New function.
1613 (w32_console_read_socket): Call it to process file notifications.

1711 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1713 * w32.c (unsetenv): Return 0 if the input string is too long.
1715 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1717 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1718 * alloc.c (xputenv): New function.
1719 * dbusbind.c (Fdbus_init_bus):
1721 * xterm.c (x_term_init):
1722 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

1732 no longer needed here.

1735 (set_time_zone_rule): Maintain the TZ=value string separately.
1736 (syms_of_editfns): Don't initialize initial_tz;
1737 init_editfns now does it.

1758 Remove USG and vlimit methods; no longer used these days.
1759 Add #error catchall just in case.
1761 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1762 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1763 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

1768 Assume SIGCHLD is defined.
1769 (parse_signal): Remove. All uses removed.
1770 (abbr_to_signal): New static function.
1771 (Fsignal_process): Use it to convert signal names to ints.
1772 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than

1788 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1790 * frame.c (make_frame): Do not set window's buffer to t.
1791 * window.c (Fsplit_window_internal): Likewise. Previously it was
1792 used to indicate that the window is being set up. Now we use
1793 set_window_buffer for all new windows, so the condition in ...
1794 (Fset_window_buffer): ... is always true and can be removed.
1796 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1798 Convenient macro to check whether the buffer is hidden.
1799 * buffer.h (BUFFER_HIDDEN_P): New macro.

1808 loop and return zero. (Bug#13086)
1810 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1812 * frame.h (x_char_width, x_char_height): Remove prototypes.

1816 * nsfns.c (x_char_width, x_char_height): Likewise.

1823 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1825 Fix a recently-introduced delete-process race condition.
1826 * callproc.c, process.h (record_kill_process):
1827 New function, containing part of the old call_process_kill.
1828 (call_process_kill): Use it.
1829 This does not change call_process_kill's behavior.
1830 * process.c (Fdelete_process): Use record_kill_process to fix a
1831 race condition that could cause Emacs to lose track of a child.
1833 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1835 Avoid code duplication between prev_frame and next_frame.
1836 * frame.c (candidate_frame): New function. Add comment.
1837 (prev_frame, next_frame): Use it. Adjust comment.
1839 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1841 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1842 fails, signal an error instead of continuing with an empty
1844 Encode expanded temp file pattern before passing it to mkstemp or
1847 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1848 Encode the file name before passing it to dostounix_filename, in
1849 case it will downcase it (under w32-downcase-file-names).
1852 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1854 Minor call-process cleanups.
1855 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1856 at the same time as other platforms, to simplify analysis.
1857 No need for fd0_volatile since we have synch_process_fd.
1858 Avoid needless emacs_close; arg is always negative.
1860 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1862 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1865 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1867 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1868 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1869 and mouse_face_hidden members to a bitfields.

1874 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1875 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1876 members to a bitfields.
1878 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1880 Don't let call-process be a zombie factory (Bug#12980).
1881 Fixing this bug required some cleanup of the signal-handling code.
1882 As a side effect, this change also fixes a longstanding rare race
1883 condition whereby Emacs could mistakenly kill unrelated processes,
1884 and it fixes a bug where a second C-g does not kill a recalcitrant
1885 synchronous process in GNU/Linux and similar platforms.
1886 The patch should also fix the last vestiges of Bug#9488,
1887 a bug which has mostly been fixed on the trunk by other changes.
1888 * callproc.c, process.h (synch_process_alive, synch_process_death)
1889 (synch_process_termsig, sync_process_retcode):
1890 Remove. All uses removed, to simplify analysis and so that
1891 less consing is done inside critical sections.
1892 * callproc.c (call_process_exited): Remove. All uses replaced
1893 with !synch_process_pid.
1894 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1895 These take the role of what used to be in unwind-protect arg.
1897 (block_child_signal, unblock_child_signal):
1898 New functions, to avoid races that could kill innocent-victim processes.
1899 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1900 (call_process_kill): Record killed processes as deleted, so that
1901 zombies do not clutter up the system. Do this inside a critical
1902 section, to avoid a race that would allow the clutter.
1903 (call_process_cleanup): Fix code so that the second C-g works again
1904 on common platforms such as GNU/Linux.
1905 (Fcall_process): Create the child process in a critical section,
1906 to fix a race condition. If creating an asynchronous process,
1907 record it as deleted so that zombies do not clutter up the system.
1908 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1909 light of these changes. Omit unnecessary call to emacs_close
1910 before failure, as the unwind-protect code does that.
1911 * callproc.c (call_process_cleanup):
1912 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1913 * process.c (record_deleted_pid): New function, containing
1914 code refactored out of Fdelete_process.
1915 (Fdelete_process): Use it.
1916 (process_status_retrieved): Remove. All callers changed to use
1917 child_status_change.
1918 (record_child_status_change): Remove, folding its contents into ...
1919 (handle_child_signal): ... this signal handler. Now, this
1920 function is purely a handler for SIGCHLD, and is not called after
1921 a synchronous waitpid returns; the synchronous code is moved to
1922 wait_for_termination. There is no need to worry about reaping
1923 more than one child now.
1924 * sysdep.c (get_child_status, child_status_changed): New functions.
1925 (wait_for_termination): Now takes int * status and bool
1926 interruptible arguments, too. Do not record child status change;
1927 that's now the caller's responsibility. All callers changed.
1928 Reimplement in terms of get_child_status.
1929 (wait_for_termination_1, interruptible_wait_for_termination):
1930 Remove. All callers changed to use wait_for_termination.
1931 * syswait.h: Include <stdbool.h>, for bool.
1932 (record_child_status_change, interruptible_wait_for_termination):
1934 (record_deleted_pid, child_status_changed): New decls.
1935 (wait_for_termination): Adjust to API changes noted above.
1937 * bytecode.c, lisp.h (Qbytecode): Remove.
1938 No longer needed after 2012-11-20 interactive-p changes.
1940 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1942 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1943 the scroll margin, move point outside the margin. (Bug#13055)

1952 * lisp.h (modify_region): Rename to...
1953 (modify_region_1): ...new prototype.
1954 * textprop.c (modify_region): Now static. Adjust users.
1955 * insdel.c (modify_region): Rename to...
1956 (modify_region_1): ...new function to work with current buffer.
1957 Adjust comment and users. Use true and false for booleans.
1959 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1961 * alloc.c (free_save_value): New function.
1962 (safe_alloca_unwind): Use it.
1963 * lisp.h (free_save_value): New prototype.
1964 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1966 (save_excursion_restore): Adjust to match saved data structure.
1967 Use free_save_value to offload some work from GC. Drop obsolete
1970 2012-12-03 Chong Yidong <cyd@gnu.org>
1972 * fileio.c (Vauto_save_list_file_name): Doc fix.
1974 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1976 * w32fns.c: Remove prototype of atof.
1977 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1979 (file_dialog_callback): Make it UINT_PTR.
1981 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1984 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1985 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1988 2012-12-03 Glenn Morris <rgm@gnu.org>
1990 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1992 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1994 Fix xpalloc confusion after memory is exhausted.
1995 * alloc.c (xpalloc): Comment fix.
1996 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1997 and signals an error, do not clear charset_table_size, as
1998 charset_table is still valid.
1999 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2001 Use execve to avoid need to munge environ (Bug#13054).
2002 * callproc.c (Fcall_process):
2003 * process.c (create_process):
2004 Don't save and restore environ; no longer needed.
2005 * callproc.c (child_setup):
2006 Use execve, not execvp, to preserve environ.
2008 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2010 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2012 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2014 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2015 display for sliced images (Bug#10500).
2017 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2019 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2021 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2022 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2024 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2026 * xdisp.c (window_outdated): Remove eassert since it hits
2027 some suspicious corner cases (see Bug#13007 and Bug#13012).
2028 (mode_line_update_needed): New function.
2029 (redisplay_internal, redisplay_window): Use it.
2030 (ensure_selected_frame): New function.
2031 (redisplay_internal, unwind_redisplay): Use it.
2032 (redisplay_internal): Move comment about buffer_shared...
2033 (buffer_shared_and_changed): ...near to its real use.
2035 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2037 * callproc.c (Fcall_process): Don't misreport vfork failure.
2039 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2041 * callproc.c (Fcall_process): Fix vfork portability problems.
2042 Do not assume that fd[0], count, filefd, and save_environ survive
2043 vfork. Fix bug whereby wrong errno value could be reported for
2044 pipe failure. Some minor cleanups, too, as follows. Move buf and
2045 bufsize to the context where they're needed. Change new_argv to
2046 be of type char **, as this is more convenient and avoids casts.
2047 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2048 Now local constants, not macros.
2050 2012-11-18 Kenichi Handa <handa@gnu.org>
2052 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2053 for the variable "f".

2057 * font.c (font_unparse_xlfd): Exclude special characters from the
2058 generating XLFD name.

2083 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2084 highlighting on the frame was cleared. Prevents assertion
2085 violations when repeatedly clicking on the "Top" link of the
2086 "bread-crumbs" in Info buffers.

2100 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2101 between bpos_covered and bpos_max. This fixes cursor display when
2102 several display strings follow each other.
2104 * .gdbinit (pgx): If the glyph's object is a string, display the
2105 pointer to string data, rather than the value of the string object
2106 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2108 * indent.c (Fvertical_motion): If the starting position is covered
2109 by a display string, return to one position before that, to avoid
2110 overshooting it inside move_it_to. (Bug#12930)
2112 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2114 * frame.h (struct frame): Remove display_preempted member

2117 * w32menu.c (pending_menu_activation): Remove since not
2119 (set_frame_menubar): Adjust user.
2120 * w32term.h (struct x_output): Drop outdated #if 0 code.

2130 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2131 of a literal "/". (Bug#12955)
2132 (gl-stamp): Invoke fc.exe directly, not through cmd.

2137 * dired.c: Assume HAVE_DIRENT_H.
2138 (NAMLEN): Remove, replacing with ...
2139 (dirent_namelen): New function. All uses changed. Use the GNU macro
2140 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2141 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2142 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2143 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2145 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2146 * ndir.h: Rename to ../nt/inc/dirent.h.
2147 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2148 Do not include <dirent.h>; no longer needed.
2149 * w32.c: Include <dirent.h> rather than "ndir.h".
2151 2012-11-23 Chong Yidong <cyd@gnu.org>
2153 * xftfont.c (xftfont_open): Remove duplicate assignment.
2155 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2157 * alloc.c (Fgarbage_collect): Unblock input after clearing
2158 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2159 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2160 * msdos.c (IT_frame_up_to_date): Use it here...
2161 * w32term.c (w32_frame_up_to_date): ...here...
2162 * xterm.c (XTframe_up_to_date): ...and here...
2163 * nsterm.m (ns_frame_up_to_date): ...but not here.
2164 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2166 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2167 Do not check whether GC is in progress.

2171 * xdisp.c (window_buffer_changed): New function.
2172 (update_menu_bar, update_tool_bar): Use it to
2173 simplify large 'if' statements.

2175 'tail' and 'frame' local variables.
2177 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2179 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2180 with Windows system header.

2201 * emacs.c (main): Set the G_SLICE environment variable for all
2202 Cygwin builds, not just GTK builds. See
2203 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2205 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2207 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2208 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2209 Define for the MSVC compiler.
2211 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2213 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2214 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2215 dostounix_filename. Prevents crashes down the road, because
2216 dostounix_filename assumes it gets a unibyte string.
2217 Reported by Michel de Ruiter <michel@sentient.nl>, see
2218 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

2249 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2250 (syms_of_eval): Remove corresponding defsubr.
2251 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2253 2012-11-19 Daniel Colascione <dancol@dancol.org>
2255 * w32fns.c (Fx_file_dialog):
2256 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2257 cygwin_convert_file_name*.
2259 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2260 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2262 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2264 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2266 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2268 * w32select.c: Include w32common.h before w32term.h, so that
2269 windows.h gets included before w32term.h uses some of its
2270 features, see below.
2272 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2274 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2283 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2285 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2286 Needed following 2012-10-20 change. (Bug#12902)
2288 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2290 * w32proc.c (waitpid): Remove unused label get_result.
2292 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2294 * makefile.w32-in (SYSWAIT_H): New macro.
2295 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2296 ($(BLD)/sysdep.$(O)): Update dependencies.
2298 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>

2302 * emacs.c, term.c (O_RDWR): Remove.
2303 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2304 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2305 * nsterm.m: Assume <fcntl.h> exists.
2306 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2307 (create_pty, Fmake_network_process, server_accept_connection)
2308 (wait_reading_process_output, init_process_emacs):
2310 (wait_reading_process_output): Put in a special case for WINDOWSNT
2311 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2312 It's not clear this is needed, but it's a more-conservative change.
2313 (create_process): Assume FD_CLOEXEC.
2314 (create_process, create_pty): Assume O_NOCTTY.
2315 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2316 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2317 Omit if not DOS_NT, since F_GETFL is not defined there.
2318 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2319 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2321 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2322 lack it, since gnulib guarantees this.
2323 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2325 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2327 * w32.c (faccessat): Pretend that directories have the execute bit
2328 set. Emacs expects that, e.g., in files.el:cd-absolute.
2330 * w32proc.c (create_child): Don't clip the PID of the child
2331 process to fit into an Emacs integer, as this is no longer a
2333 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2334 reaping only the process specified by PID argument, if that is
2335 positive. Use PID instead of dead_child to know which process to
2336 reap. Wait for the child to die only if WNOHANG is not in
2338 (sys_select): Don't set dead_child.
2340 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2341 as it is no longer needed.
2343 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2345 (record_child_status_change): Remove the setting of
2346 record_at_most_one_child for the !WNOHANG case.
2348 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2350 Fix problems in ns port found by static checking.
2351 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2352 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2353 not to process group.
2354 (ns_select): Use emacs_write, not write, as that's more robust
2355 in the presence of signals.
2356 (fd_handler:): Check for read errors.
2358 2012-11-16 Glenn Morris <rgm@gnu.org>
2360 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2362 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2364 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2366 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2368 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2369 use the same value of thread handle.
2370 (start_timer_thread): If the timer thread exited (due to error),
2371 clean up by closing the two handles it used. Duplicate the caller
2372 thread's handle here, so it gets duplicated only once, when
2373 launching the timer thread. Set priority of the timer thread, not
2375 (getitimer): Don't duplicate the caller thread's handle here.
2378 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2380 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2383 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2385 Remove no-longer-used pty_max_bytes variable.
2386 * process.c (pty_max_bytes): Remove; unused.
2387 (send_process): Do not set it.
2389 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2391 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2392 Update dependencies.
2394 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2396 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2397 This follows up on the 2012-09-29 patch that removed indirection
2398 for the 'function' field. Reported by Sergey Vinokurov in
2399 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2401 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2403 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2404 different name, as the MS runtime does not have such a function,
2405 and probably never will.) All callers changed. Ignore DIRFD
2406 value if PATH is an absolute file name, to match Posix spec
2407 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2410 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2412 * xdisp.c (echo_area_display, redisplay_internal):
2413 Omit redundant check whether frame_garbaged is set.
2415 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2417 Use faccessat, not access, when checking file permissions (Bug#12632).
2418 This fixes a bug that has been present in Emacs since its creation.
2419 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2420 which must set some sort of record. (Torek's bug report was against
2421 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2422 same common flaw.) See Torek's Usenet posting
2423 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2424 Posted: Fri Apr 8 14:18:56 1983.
2425 * Makefile.in (LIB_EACCESS): New macro.
2427 * callproc.c (init_callproc):
2428 * charset.c (init_charset):
2429 * fileio.c (check_existing, check_executable, check_writable)
2431 * lread.c (openp, load_path_check):
2432 * process.c (allocate_pty):
2434 Use effective UID when checking permissions, not real UID.
2435 * callproc.c (init_callproc):
2436 * charset.c (init_charset):
2437 * lread.c (load_path_check, init_lread):
2438 Test whether directories are accessible, not merely whether they exist.
2439 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2440 * fileio.c (check_existing, check_executable, check_writable)
2442 Use symbolic names instead of integers for the flags, as they're
2444 (check_writable): New arg AMODE. All uses changed.
2445 Set errno on failure.
2446 (Ffile_readable_p): Use faccessat, not stat + open + close.
2447 (Ffile_writable_p): No need to call check_existing + check_writable.
2448 Just call check_writable and then look at errno. This saves a syscall.
2449 dir should never be nil; replace an unnecessary runtime check
2450 with an eassert. When checking the parent directory of a nonexistent
2451 file, check that the directory is searchable as well as writable, as
2452 we can't create files in unsearchable directories.
2453 (file_directory_p): New function, which uses 'stat' on most platforms
2454 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2455 (Ffile_directory_p, Fset_file_times): Use it.
2456 (file_accessible_directory_p): New function, which uses a single
2457 syscall for efficiency.
2458 (Ffile_accessible_directory_p): Use it.
2459 * xrdb.c (file_p): Use file_directory_p.
2460 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2461 * lread.c (openp): When opening a file, use fstat rather than
2462 stat, as that avoids a permissions race. When not opening a file,
2463 use file_directory_p rather than stat.
2464 (dir_warning): First arg is now a usage string, not a format.
2465 Use errno. All uses changed.
2466 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2467 that merely introduced a race.
2468 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2469 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2470 and similarly for the other O_* flags.
2471 * w32.c (sys_faccessat): Rename from sys_access and switch to
2472 faccessat's API. All uses changed.
2473 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2474 (magic_db): Rename from magic_file_p.
2475 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2476 char *, so that we don't have to test for file existence
2477 separately from opening the file for reading. This removes a race
2478 fixes a permission-checking problem, and simplifies the code.
2480 (file_p): Remove; no longer needed.
2482 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2484 Omit glyphs initialization at startup.
2485 * dispnew.c (glyphs_initialized_initially_p): Remove.
2486 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2487 (Fredraw_frame): Move actual code from here...
2488 (redraw_frame): ...to here. Add eassert. Adjust comment.
2489 (Fredraw_display): Use redraw_frame.
2490 * xdisp.c (clear_garbaged_frames): Likewise.
2492 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2494 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2495 passed to pint2str and pint2hrstr to be at most the size of the
2496 frame's decode_mode_spec_buffer. This avoids crashes with very
2497 large values of FIELD_WIDTH argument to decode_mode_spec.
2500 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2502 Fix a race with verify-visited-file-modtime (Bug#12863).
2503 Since at least 1991 Emacs has ignored an mtime difference of no
2504 more than one second, but my guess is that this was to work around
2505 file system bugs that were fixed long ago. Since the race is
2506 causing problems now, let's remove that code.
2507 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2508 whose time stamp is off by no more than a second. Insist that the
2509 file time stamps match exactly.
2511 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2513 * frame.h (struct frame): Convert external_tool_bar member to
2514 1-bit unsigned bitfield.
2515 * termhooks.h (struct terminal): Remove mouse_moved member since
2516 all users are long dead. Adjust comment on mouse_position_hook.
2518 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2520 Simplify by using FOR_EACH_FRAME here and there.
2521 * frame.c (next_frame, prev_frame, other_visible_frames)
2522 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2523 * w32term.c (x_window_to_scroll_bar): Likewise.
2524 * window.c (window_list): Likewise.
2525 * xdisp.c (x_consider_frame_title): Likewise.
2526 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2527 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2528 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2529 * xmenu.c (menubar_id_to_frame): Likewise.
2530 * xselect.c (frame_for_x_selection): Likewise.
2531 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2532 (x_window_to_menu_bar): Likewise.
2533 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2535 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2537 * data.c (Qdefalias_fset_function): Now static.
2539 Another tweak to vectorlike_header change.
2540 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2541 Remove, and replace all uses with ...
2542 (next_in_free_list, set_next_in_free_list):
2543 New functions, which respect C's aliasing rules better.
2545 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2547 * window.c (list4i): Rename from 'quad'. All uses changed.
2548 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2550 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2552 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2553 warning about mixing declarations and code in ISO C90.
2555 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2557 * window.c (Fsplit_window_internal): Set combination limit of
2558 new parent window to t iff Vwindow_combination_limit is t;
2559 fixing a regression introduced with the change from 2012-09-22.
2560 (Fset_window_combination_limit): Fix doc-string.
2562 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2564 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2565 amount when the scroll margins are too large. When scrolling
2566 backwards in the buffer, give up if cannot reach point or the
2567 scroll margin within a reasonable number of screen lines.
2568 Fixes point position in window under scroll-up/down-aggressively when
2569 point is positioned many lines beyond the window top/bottom.
2572 * ralloc.c (relinquish): If real_morecore fails to return memory
2573 to the system, don't crash; instead, leave the last heap
2574 unchanged and return. (Bug#12774)
2576 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2578 * lisp.h (AUTOLOADP): New macro.
2579 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2580 * data.c (Ffset): Remove special ad-advice-info handling.
2581 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2583 (Finteractive_form): Simplify.
2584 (Fquo): Don't insist on having at least 2 arguments.
2585 (Qdefalias_fset_function): New var.
2587 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2589 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2591 * nsfont.m (Qcondensed, Qexpanded): New variables.
2592 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2593 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2595 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2597 Fix recently introduced crash on MS-Windows (Bug#12839).
2598 * w32term.h (struct scroll_bar): Use convenient header.
2599 (SCROLL_BAR_VEC_SIZE): Remove.
2600 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2602 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2604 Tweak last vectorlike_header change.
2605 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2606 vectorlike object on the free list. This is introduced to avoid
2607 some (but not all) pointer casting and aliasing problems, see
2608 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2609 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2611 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2613 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2615 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2616 been removed, so remove them here also.
2618 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2620 * doc.c (Fdocumentation): Handle new property
2621 dynamic-docstring-function to replace the old ad-advice-info.
2623 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2625 * fns.c (Qeql, hashtest_eq): Now static.
2627 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2629 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2630 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2631 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2632 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2634 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2636 Use same hash function for hashfn_profiler as for hash_string etc.
2637 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2638 * lisp.h (sxhash_combine): New inline function, with the contents
2639 of the old SXHASH_COMBINE.
2640 * profiler.c (hashfn_profiler): Use it, instead of having a
2641 special hash function containing a comparison that always yields 1.
2643 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2645 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2646 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2647 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2650 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2652 * image.c (xpm_make_color_table_h): Fix compiler error because
2653 make_hash_table changed.
2655 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2657 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2659 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2661 Use ad-hoc comparison function for the profiler's hash-tables.
2662 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2663 (make_log): Use them.
2664 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2665 call Fequal any more.
2666 (Ffunction_equal): New function.
2667 (cmpfn_profiler, hashfn_profiler): New functions.

2674 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2675 (hash_lookup, hash_remove_from_table): Move assertion checking of
2676 hashfn result here. Check hash-equality before calling cmpfn.

2683 * print.c (print_object): Adjust to new hash-table struct.
2684 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2686 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2688 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2689 value of w32-scroll-lock-modifier is neither nil nor one of the
2690 known key modifiers. (Bug#12806)
2692 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2694 Shrink struct vectorlike_header to the only size field.
2695 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2697 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2698 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2699 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2700 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2701 information from the vector header. Adjust comment.
2702 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2703 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2705 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.

2709 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
2710 (sweep_string, lisp_malloc): Remove useless prototypes.
2711 (enum mem_type): Adjust comment.
2712 (NEXT_IN_FREE_LIST): New macro.
2713 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2714 (Fmake_bool_vector): Likewise.
2715 (struct large_vector): New type to represent allocation unit for
2716 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2717 (large_vectors): Change type to struct large_vector.
2718 (allocate_vector_from_block): Simplify.
2719 (PSEUDOVECTOR_NBYTES): Replace with...
2720 (vector_nbytes): ...new function. Adjust users.
2721 (sweep_vectors): Adjust processing of large vectors.
2722 (allocate_vectorlike): Likewise.
2723 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2724 Add easserts. Adjust XSETPVECTYPESIZE usage.
2725 (allocate_buffer): Use BUFFER_PVEC_INIT.
2726 (live_vector_p): Adjust to match large vector.
2727 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2728 * buffer.h (struct buffer): Add next member.
2729 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2731 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2732 * fns.c (internal_equal): Adjust to match enum pvec_type change.

2734 * lread.c (defsubr): Use XSETPVECTYPE.
2735 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2736 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2737 (xvecsize): New command.
2739 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2741 * keyboard.c (event_to_kboard): Do not dereference
2742 frame_or_window field of SELECTION_REQUEST_EVENT
2743 and SELECTION_CLEAR_EVENT events (Bug#12814).
2744 * xterm.h (struct selection_input_event): Adjust comment.
2746 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2748 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2749 such as Scroll Lock, if the respective keys are treated as
2750 function keys, not as modifiers. This avoids destroying non-ASCII
2751 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2753 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2755 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2757 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2759 Restore some duplicate definitions (Bug#12814).
2760 This undoes part of the 2012-11-03 changes. Some people build
2761 with plain -g rather than with -g3, and they need the duplicate
2762 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2763 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2764 Define as macros, as well as as enums or as constants.
2766 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2768 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2769 to keypad keys (Bug#12816).
2771 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2773 Minor adjustments of recently-changed frame functions.
2774 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2775 known to be a frame (we're in the FRAMEP branch).
2776 * lisp.h (Qframep): Remove decl. frame.h declares this.
2777 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2778 since they're meant for Lisp fixnum values.
2780 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2782 * window.c (Fwindow_combination_limit): Revert to the only
2783 required argument and adjust docstring as suggested in
2784 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2785 by Martin Rudalics <rudalics@gmx.at>.
2787 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2789 Widely used frame validity and checking functions.
2790 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2791 * frame.c (decode_live_frame, decode_any_frame): New functions.
2792 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2793 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2794 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2795 (Fframe_pointer_visible_p): Use decode_any_frame.
2796 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2797 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2798 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2799 (Fframe_focus): Likewise. Allow zero number of arguments.
2801 (frame_buffer_list, frame_buffer_predicate): Remove.
2802 * lisp.h (frame_buffer_predicate): Remove prototype.
2803 * buffer.c (Fother_buffer): Use decode_any_frame.
2804 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2805 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2806 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2807 (Fclose_font, Ffont_info): Use decode_live_frame.
2808 * fontset.c (check_fontset_name): Likewise.
2809 * terminal.c (Fframe_terminal): Likewise.
2810 * w32fns.c (check_x_frame): Likewise.
2811 * window.c (Fminibuffer_window, Fwindow_at)
2812 (Fcurrent_window_configuration): Likewise.
2813 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2814 Likewise. Allow zero number of arguments. Adjust docstring.
2815 * dispnew.c (Fredraw_frame): Likewise.
2816 * xfaces.c (frame_or_selected_frame): Remove.
2817 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2818 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2819 (Fframe_face_alist): Use decode_live_frame.
2820 * xfns.c (check_x_frame): Likewise.
2822 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2824 * window.c (quad): New function.
2825 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2826 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2827 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2828 (Fwindow_line_height): Use it.
2829 (Fwindow_fringes): Use list3.
2830 (Fwindow_scroll_bars): Use list4.
2831 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2832 (Fwindow_combination_limit): Allow zero number of arguments.
2834 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2836 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2838 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2839 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2840 file descriptor 2 for standard error. (Bug#12805)
2842 2012-11-05 Chong Yidong <cyd@gnu.org>
2844 * process.c (wait_reading_process_output): Revert previous change.
2846 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2848 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2849 This removes code that has been obsolete since around 1990.
2850 * callproc.c (Fcall_process):
2852 * process.c (create_process):
2853 * term.c (dissociate_if_controlling_tty):
2854 Assume setsid exists.
2855 * callproc.c (child_setup): Assume setpgid exists and behaves as
2856 per POSIX.1-1988 or later.
2857 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2858 * emacs.c (shut_down_emacs):
2859 * sysdep.c (sys_suspend, init_foreground_group):
2860 Assume getpgrp behaves as per POSIX.1-1998 or later.
2861 * msdos.c (setpgrp): Remove.
2862 (tcgetpgrp, setpgid, setsid): New functions.
2863 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2864 * term.c (no_controlling_tty): Remove; unused.
2865 * w32proc.c (setpgrp): Remove.
2866 (setsid, tcgetpgrp): New functions.
2868 Simplify by assuming __fpending.
2869 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2870 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2871 Do not assume that __fpending's result fits in int.
2873 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2875 Remove EMACS_OUTQSIZE+sleep hack.
2876 * dispnew.c (update_frame_1): Remove hack for terminals slower
2877 than 2400 bps, which throttled Emacs by having it sleep.
2878 This code hasn't worked since at least 2007, when the multi-tty stuff
2879 was added, and anyway those old terminals are long dead.
2880 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2881 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2883 Fix data-loss with --version (Bug#9574).
2884 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2885 as we can't assume that emacs_strerror is initialized, and strerror
2886 is good enough here.
2887 (main): Invoke atexit earlier, to catch earlier instances of
2888 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2890 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2892 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2893 (keyDown): Remap keypad keys to X11 virtual key codes.
2895 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2897 Fix data-loss with --batch (Bug#9574).
2898 * emacs.c: Include <close-stream.h>.
2899 (close_output_streams): New function.
2900 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2901 and handles errors appropriately.
2902 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2905 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2906 The symptom is a diagnostic "GLib-WARNING **: In call to
2907 g_spawn_sync(), exit status of a child process was requested but
2908 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2909 waitpid(), so exit status can't be returned." The diagnostic
2910 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2911 The real bug is a race condition between Emacs and glib: Emacs
2912 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2913 so that glib can't find it. Work around the bug by invoking
2914 waitpid only on subprocesses that Emacs itself creates.
2915 * process.c (create_process, record_child_status_change):
2916 Don't use special value -1 in pid field, as the caller now must
2917 know the pid rather than having the callee infer it.
2918 The inference was sometimes incorrect anyway, due to another race.
2919 (create_process): Set new 'alive' member if child is created.
2920 (process_status_retrieved): New function.
2921 (record_child_status_change): Use it.
2922 Accept negative 1st argument, which means to wait for the
2923 processes that Emacs already knows about. Move special-case code
2924 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2925 processes that have already been waited for, by testing and
2926 clearing new 'alive' member.
2927 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2928 now does this internally.
2929 (handle_child_signal): Let record_child_status_change do all
2930 the work, since we do not want to reap all exited child processes,
2931 only the child processes that Emacs itself created.
2932 * process.h (Lisp_Process): New boolean member 'alive'.
2934 Omit duplicate definitions no longer needed with gcc -g3.
2935 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2936 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2937 Define only as macros. There's no longer any need to also define
2938 these symbols as enums or as constants, since we now assume
2939 gcc -g3 when debugging.
2941 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2943 * lisp.mk: Adjust comments to the fact that term/internal is now
2944 loaded from loadup.el.
2946 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2947 (msdos_fatal_signal): New function.
2948 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2951 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2952 for GCC versions before 4.
2953 (emacs_raise): Define to call msdos_fatal_signal.
2955 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2956 iterator when starting in the middle of a display or overlay
2959 2012-11-03 Chong Yidong <cyd@gnu.org>
2961 * process.c (wait_reading_process_output): Clean up the last
2964 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2966 * process.c (wait_reading_process_output): Avoid a race condition
2967 with SIGIO delivery (Bug#11536).
2969 2012-11-03 Chong Yidong <cyd@gnu.org>
2971 * buffer.c (cursor_type): Untabify docstring.
2973 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2975 * frame.h (struct frame): Drop can_have_scroll_bars member
2976 which is meaningless for a long time. Adjust comments.
2977 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2978 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2980 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2982 * window.c (decode_next_window_args): Update window arg after
2983 calling decode_live_window and so fix crash reported at
2984 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2985 by Juanma Barranquero <lekktu@gmail.com>.
2986 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2987 * font.c (Ffont_at): Likewise.
2989 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2991 * widget.c (resize_cb): New function.
2992 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2993 (EmacsFrameResize): Check if all is up to date before changing frame
2996 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2998 Implement backtrace output for fatal errors on MS-Windows.
2999 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3000 (BACKTRACE_LIMIT_MAX): New macro.
3001 (w32_backtrace): New function.
3002 (emacs_abort): Use w32_backtrace when the user chooses not to
3003 attach a debugger. Update the text of the abort dialog.
3005 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3007 Window-related stuff cleanup here and there.
3008 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3009 Use decode_any_window.
3010 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3011 * xdisp.c (Fformat_mode_line): Likewise.
3012 * font.c (Ffont_at): Use decode_live_window.
3013 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3014 * window.c (decode_next_window_args): Likewise.
3015 (decode_any_window): Remove static.
3016 * window.h (decode_any_window): Add prototype.
3017 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3018 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3021 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3023 Remove pad from struct input_event.
3024 * termhooks.h (struct input_event): Remove padding field.
3026 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3027 member is never cons for a long time. Adjust comment.
3028 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3029 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3030 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3031 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3033 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3035 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3037 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3039 Fix crash when using Emacs as commit editor for git (Bug#12697).
3040 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3041 and it is configured in conf_post.h.
3042 (Fcall_process): Don't invoke both setsid and setpgid; the former
3043 is enough, if it exists.
3044 * callproc.c (Fcall_process, child_setup):
3045 * process.c (create_process): Use setpgid.
3046 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3048 * dispnew.c (init_display): Initialize the foreground group
3049 if we are running a tty display.
3050 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3051 * lisp.h (init_foreground_group): New decl.
3052 * sysdep.c (inherited_pgroup): New static var.
3053 (init_foreground_group, tcsetpgrp_without_stopping)
3054 (narrow_foreground_group, widen_foreground_group): New functions.
3055 (init_sys_modes): Narrow foreground group.
3056 (reset_sys_modes): Widen foreground group.
3058 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3060 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3062 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3064 * minibuf.c (read_minibuf): Restore current buffer since
3065 choose_minibuf_frame calling Fset_frame_selected_window may
3066 change it (Bug#12766).
3068 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3070 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3072 2012-10-30 Kenichi Handa <handa@gnu.org>
3074 * font.c (Ffont_at): If WINDOW is specified and it is not
3075 displaying the current buffer, signal an error.
3077 2012-10-29 Daniel Colascione <dancol@dancol.org>
3079 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3080 In preparation for fixing bug#12739, move these functions from
3083 * coding.h, coding.c: ... to here, and compile them only when
3084 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3085 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3087 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3089 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3090 (timer_loop, getitimer, setitimer): Use it instead of
3091 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3093 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3096 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3098 * nsterm.m (NO_APPDEFINED_DATA): New define.
3099 (last_appdefined_event_data): New variable
3100 (last_appdefined_event): Remove.
3101 (ns_select): Initialize t from last_appdefined_event_data instead
3102 of [last_appdefined_event data1].
3103 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3104 remove last_appdefined_event (Bug#12698).
3106 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3108 * frame.c (x_set_font): Catch internal error.
3110 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3112 Avoid overflow in w32 implementation of interval timers.
3113 When possible, for ITIMER_PROF count only times the main thread
3115 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3116 'volatile ULONGLONG' types. All the other data which was
3117 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3118 (GetThreadTimes_Proc): New typedef.
3119 (w32_get_timer_time): New function, returns a suitable time value
3121 (timer_loop): Enter critical section when accessing ULONGLONG
3122 values of the itimer_data struct, as these accesses are no longer
3123 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3124 Remove unused variable.
3125 (init_timers): Initialize s_pfn_Get_Thread_Times.
3126 (start_timer_thread): Don't assign itimer->caller_thread here.
3127 (getitimer): Assign itimer->caller_thread here.
3128 (setitimer): Always call getitimer to get the value of ticks_now.
3129 (sys_spawnve): Avoid compiler warning about format mismatch.
3131 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3133 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3134 mouse movement events if the menu bar is active. This avoids
3135 producing a busy "hour-glass" cursor by Windows if the mouse
3136 pointer is positioned over a tooltip shown for some menu item.
3138 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3140 Don't assume process IDs fit in int.
3141 * emacs.c (shut_down_emacs) [!DOS_NT]:
3142 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3143 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3144 Use pid_t, not int, to store process IDs, as 'int'
3145 is not wide enough on a few platforms (e.g., AIX and IRIX).
3147 2012-10-23 Kenichi Handa <handa@gnu.org>
3149 The following change is to make face-font-rescale-alist work
3150 correctly for non-ASCII fonts.
3152 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3153 (font_open_for_lface): Handle Vface_font_rescale_alist.
3155 2012-10-23 Chong Yidong <cyd@gnu.org>
3157 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3159 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3161 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3163 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3165 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3168 2012-10-21 Glenn Morris <rgm@gnu.org>
3170 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3172 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3174 Port to OpenBSD 5.1.
3175 * frame.c (Fmouse_position, Fmouse_pixel_position):
3176 * xdisp.c (produce_stretch_glyph):
3177 Declare local vars only when they're needed.
3178 This is clearer and avoids a warning on OpenBSD about unused vars.
3179 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3180 This is safer, and avoids OpenBSD warnings about unused vars.
3181 * keyboard.c (record_menu_key): Remove unnecessary decl.
3182 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3183 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3184 as our definition clashes with OpenBSD's.
3185 * xfaces.c (load_face_colors, check_lface_attrs)
3186 (get_lface_attributes_no_remap, get_lface_attributes)
3187 (lface_fully_specified_p, x_supports_face_attributes_p)
3188 (tty_supports_face_attributes_p, face_fontset, realize_face)
3189 (realize_x_face, realize_tty_face):
3190 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3191 merely Lisp_Object *. This is more informative and avoids
3192 a warning on OpenBSD about accessing beyond an object's size.
3194 2012-10-20 Chong Yidong <cyd@gnu.org>
3196 * lread.c (Fload): Doc fix (Bug#12592).
3198 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3200 * font.c (Ffont_at): Fix previous change.
3202 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3204 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3205 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3208 * alloc.c (NSTATICS): Decrease to 0x800.
3210 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
3212 * fns.c (Fnreverse): Include the problem element when signaling an
3215 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
3217 * nsterm.m (ns_select): Check writefds before call to
3218 FD_ISSET (Bug#12668).
3220 2012-10-18 Daniel Colascione <dancol@dancol.org>
3222 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3223 (staticpro): If we run out of staticpro slots, die with an
3224 informative error instead of just calling emacs_abort.
3226 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3228 Fix two flaws reported by Dmitry Antipov.
3229 * window.c (Ftemp_output_buffer_show): Remove.
3230 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
3231 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
3233 2012-10-17 Eli Zaretskii <eliz@gnu.org>
3235 * makefile.w32-in ($(BLD)/w32.$(O)):
3236 ($(BLD)/vm-limit.$(O)):
3238 ($(BLD)/unexw32.$(O)):
3239 ($(BLD)/fileio.$(O)):
3240 ($(BLD)/dispnew.$(O)): Update dependencies.
3242 * w32term.h (w32_initialize_display_info, initialize_w32_display):

3483 since unsigned is guaranteed to have that behavior and signed is not.
3484 (read_char): Use ptrdiff_t for string length.
3485 (get_input_pending): Remove first argument, since it was always
3486 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3487 and behave as if it had that value. Return new value of
3488 input_pending. All callers changed.
3489 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3490 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3493 All callers changed.

3519 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3521 * commands.h (immediate_quit): Remove duplicate decl.

3533 match what GetLastError returns. Explain why the function is
3536 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3537 'is_tooltip_frame', to avoid confusion with its global namesake.
3539 2012-10-08 Daniel Colascione <dancol@dancol.org>
3541 * xdisp.c (start_hourglass): Call w32_note_current_window when
3542 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3543 build that caused Emacs to display the hourglass cursor forever.
3545 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3546 which is broken under remote desktop, calculate the number of
3547 colors available for a display based on the display's number of
3548 planes and number of bits per pixel per plane. (bug#10397).
3550 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3552 * nsfont.m (Vfonts_in_cache): New variable.
3553 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3554 are used. Add cached fonts to Vfonts_in_cache.
3555 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3557 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3559 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now

3579 ($(BLD)/w32proc.$(O)): Add w32common.h.
3581 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3583 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3585 2012-10-08 Daniel Colascione <dancol@dancol.org>
3587 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3588 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3589 accidental message numbering hole. Change other messages to

3607 Remove duplicate definitions.
3609 * w32fns.c: Include w32common.h; include w32heap.h only in
3612 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3613 Use `report_file_error' instead of `error' in order to better
3614 inform users of what went wrong. Increase NTGUI_UNICODE file
3615 dialog box file name length to 32k, the maximum allowed by the NT
3618 * w32common.h: New file.
3619 (ROUND_UP, ROUND_DOWN, get_page_size)
3620 (get_allocation_unit, get_processor_type, get_w32_major_version)

3623 (OS_NT, os_subtype, cache_system_info): Move here.
3625 * unexw32.c, unexcw.c: Include w32common.h.
3627 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3628 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3629 to call syms_of_w32select.
3631 * cygw32.h: Remove obsolete EXFUN declarations.
3633 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3645 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3647 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3650 2012-10-08 Daniel Colascione <dancol@dancol.org>
3652 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3653 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3654 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

3657 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3658 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3659 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3660 now a supported configuration.
3662 * Makefile.in: consolidate image variables into LIBIMAGE; add
3663 W32_OBJ and W32_LIBS. Compile new files.
3666 (_DebPrint) declare tracing facility for W32 debugging. We need
3667 to unify tracing later.
3669 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3670 unconditional use of W32 Unicode functions. Cygwin runs only on
3671 100% Unicode operating systems.
3673 * cygw32.c: New file. Define Cygwin-specific facilities.
3674 (Fcygwin_convert_path_to_windows)
3675 (Fcygwin_convert_path_from_windows): New user functions for
3676 accessing Cygwin path-munging routines.
3678 * cygw32.h: New file.
3679 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3680 UTF-16LE strings temporarily inside non-Lisp-visible string
3683 (w32_strerror): Just what it says on the tin.
3685 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3686 also run for Cygwin; both systems have the same problem with using
3687 GUI facilities in a forked child. Also call syms_of_cygw32,
3688 syms_of_w32select in correct places.
3690 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3691 needs fork-then-exec for daemon launching.
3693 * font.h: Include frame.h.
3695 * image.c: Use the image library cache machinery only when we're
3696 compiling for native WINDOWSNT; Cygwin can use shared libraries
3697 like any other Unixlike system.
3699 * keyboard.c: Clarify a comment regarding the input loop.
3701 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3702 functions directly instead of trying to detect at runtime that our
3703 host operating system supports them. We make this change for two
3704 reasons: Cygwin lacks support for the multibyte character
3705 conversion functions used by the legacy menu code, and Cygwin
3706 never needs to rely on non-Unicode APIs.
3708 * unexw32.c (hinst): Declare extern.
3710 * w32.c: Change header order;
3711 (w32_strerror): Move to w32fns.c because we need it for
3712 non-WINDOWSNT builds.
3714 * w32.h: Add #error macro to make sure we don't include w32.h for
3715 Cygwin builds. Remove w32select declarations.
3717 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3718 w32fns.c. w32console.c is WINDOWSNT-only.
3720 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3721 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3723 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3724 (w32_major_version, w32_minor_version, w32_build_number)
3725 (os_subtype, sound_type): Define here
3726 (w32_defined_color): Make color parameter const for consistency
3727 with other _defined_color functions.
3728 (w32_createwindow): Unconditionally call w32_init_class instead of
3729 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3730 through the code is complex and unnecessary because class
3731 registration is practically free.
3732 (w32_name_of_message): New EMACSDEBUG-only function.
3733 (Fset_message_beep): Move here
3734 (Fx_open_connection): Require that the display name for Windows be
3735 "w32" for consistency, emacsclient disambiguation, and maybe, one
3736 day, multi-window-system support.
3737 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3738 Cygwin files for W32 GUI facilities, since these clearly don't
3739 expect Cygwin names.
3740 (_DebPrint): Define.
3741 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3742 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3743 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3744 (w32_last_error): Remove.
3746 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3748 * w32heap.c (syspage_mask): Declare here.
3749 (cache_system_info): Remove.
3751 * w32inevt.c (faked_key): Define globally, not statically.
3752 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3753 (w32_console_toggle_lock_key): Move to w32fns.c.
3755 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3757 * w32proc.c (_DebPrint): Move to w32fns.c.
3758 * w32select.c: Include string.h, stdio.h for Cygwin.
3759 * w32select.h: New File.
3761 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3763 (w32_message_fd): New variable. Under Cygwin, holds the file
3764 descriptor the system used to tell us about pending thread
3767 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3768 that prevented compilation under non-WINDOWSNT systems.
3770 (w32_initialize): Open /dev/windows and assign it to
3771 w32_message_fd. Provide w32 feature.
3773 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3774 (WM_EMACS_INPUT_READY): add.
3775 (prepend_msg, w32_message_fd): Declare globally.
3778 (keyboard_handle): Use only when WINDOWSNT.
3779 (notify_msg_ready): New function. Posts a message to the main
3780 thread's message queue under CYGWIN, which wakes up the main
3781 thread from select(2) by making the /dev/windows file descriptor
3782 ready. Under WINDOWSNT, it sets an event the same way the old
3785 (post, prepend_msg): Actually call notify_msg_ready instead of
3786 setting the input event directly.
3788 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3790 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3791 but it still has blocs in it, don't return it to the system,
3792 instead of aborting. (Bug#12402)
3794 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3796 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3798 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3799 MAC_OS_X_VERSION_10_6.

3809 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3810 MAC_OS_X_VERSION_10_2.
3812 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3814 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3815 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3817 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3818 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.

3827 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3829 Improve sys_siglist detection.
3830 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3831 defined as a macro, as is done in Solaris.
3832 (sys_siglist_entries): New macro.
3833 (save_strsignal): Use it.
3834 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3835 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3837 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3839 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3840 fullscreen/Fullscreen.
3842 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3843 tobar_height is new.
3845 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3846 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3847 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3848 (windowDidResize:): Check for correct window if old style fullscreen.
3849 Capitalize word in comment. Remove incorrect comment.
3850 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3851 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3852 error in drawing background.
3853 (toggleFullScreen:): Remove comment. Rearrange calls.
3854 Set toolbar values to zero, save old height in tobar_height.
3855 Restore tool bar height when leaving fullscreen.
3856 (canBecomeMainWindow): New function.
3858 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3860 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3862 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3864 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3866 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3867 that time stamps of directories could also be changed.
3868 Don't request the too broad GENERIC_WRITE, only the more restrictive
3869 FILE_WRITE_ATTRIBUTES access rights.
3871 * fileio.c (Fset_file_times): Special-case ignoring errors for
3872 directories only on MSDOS, not on MS-Windows.
3874 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3876 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3878 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3880 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3881 see whether CreateFile failed.
3883 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3885 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3886 to avoid similar races.
3887 * keyboard.c (pending_signals): Now bool, not int.
3889 Port timers to OpenBSD, plus check for timer failures.
3890 OpenBSD problem reported by Han Boetes.
3891 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3893 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3894 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3895 like OpenBSD, which has timer_settime but does not declare it.
3896 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3897 whether to use itimerspec-related primitives. All uses of
3898 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3900 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3902 * profiler.c (handle_profiler_signal): Fix a malloc race
3903 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3905 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3907 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3909 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3911 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3912 consistent with the change in return value of 'safe_strsignal'.
3914 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3916 Prefer plain 'static' to 'static inline' (Bug#12541).
3917 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3918 (bidi_set_sor_type, bidi_push_embedding_level)
3919 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

3924 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3925 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3926 Now 'static', not 'static inline'.
3928 Count overruns when profiling; change units to ns.
3929 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3930 Give extra weight to samples after overruns, to attempt to count
3931 the time more accurately.
3932 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3933 the underlying primitives nominally do ns.
3934 (Fprofiler_cpu_start): Document the change. Mention that
3935 the sampling intervals are only approximate.
3937 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3939 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3941 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3942 case for the special 0 coding-system.
3944 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3945 (Fmake_overlay): Remove redundant tests.
3946 (fix_start_end_in_overlays): Remove redundant recentering.
3948 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3950 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3951 Update dependencies.
3953 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3955 Fix a malloc race condition involving strsignal.
3956 A signal can arrive in the middle of a malloc, and Emacs's signal
3957 handler can invoke strsignal, which can invoke malloc, which is
3958 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3959 Fix it by altering the signal handler so that it does not invoke
3961 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3962 * process.c (status_message): Use const pointer, in case strsignal
3963 is #defined to safe_strsignal.
3964 * sysdep.c (sys_siglist, init_signals): Always define and
3965 initialize a substitute sys_siglist if the system does not define
3966 one, even if HAVE_STRSIGNAL.
3967 (safe_strsignal): Rename from strsignal. Always define,
3968 using sys_siglist. Return a const pointer.
3969 * syssignal.h (safe_strsignal): New decl.
3970 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3972 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3974 * w32proc.c (timer_loop): Fix code that waits for timer
3975 expiration, to avoid high CPU usage.
3977 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3979 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3980 (sweep_weak_table): Remove redundant prototypes.
3982 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3984 * emacs.c: Move the inclusion of TERM_HEADER after including
3985 windows.h on WINDOWSNT. This avoids compilation problems with
3988 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3990 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3991 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3992 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3993 as the previous version used 'void *'.
3995 * ralloc.c (ROUNDUP): Fix last change.
3996 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3999 * w32proc.c <disable_itimers>: New static flag.
4000 (init_timers): Initialize it to zero, after creating the critical
4001 sections used by the timer threads.
4002 (term_timers): Set to 1 before deleting the critical sections.
4003 (getitimer, setitimer): If disable_itimers is non-zero, return an
4004 error indication without doing anything. Reported by Fabrice
4005 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4006 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4008 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4011 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4012 term_ntproc after all the other bookkeeping, to get timers working
4013 as long as possible.
4015 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4017 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4018 Suggested by Juri Linkov in
4019 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4021 Prefer plain 'static' to 'static inline' (Bug#12541).
4022 With static functions, modern compilers inline pretty well by
4023 themselves; advice from programmers often hurts as much as it helps.
4024 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4025 this change shrinks the text size of the Emacs executable by 1.1%
4026 without affecting CPU significantly in my benchmark.
4027 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4102 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
4103 Now 'static', not 'static inline'.
4106 (bidi_copy_it): Do the whole copy with a single memcpy.
4107 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4109 Revert the FOLLOW-SYMLINKS change for file-attributes.
4110 Doing it right would require several changes to Tramp, and there's
4111 not enough time to get that tested before the freeze today.
4112 * dired.c (directory_files_internal, Ffile_attributes):
4115 * frame.c (x_report_frame_params): Port better to wider ints.
4116 Do not assume that EMACS_UINT is the same width as uprintmax_t,
4117 or that pointers can be printed in 15 decimal digits.
4118 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
4120 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

4149 * w32.c (init_environment, get_emacs_configuration): Support AMD64
4151 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
4152 compatibility with x64.
4154 * vm-limit.c (lim_data): Now size_t.
4155 (check_memory_limits): Adjust prototypes of real_morecore and
4156 __morecore to receive argument of type ptrdiff_t. Use size_t for
4157 five_percent and data_size.
4159 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope

4299 Suggested by Eli Zaretskii in
4300 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
4302 2012-09-30 Eli Zaretskii <eliz@gnu.org>
4304 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
4305 HAVE_TIMER_SETTIME is defined.

4309 Profiler improvements: more-accurate timers, overflow checks.
4310 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4311 signal.h, setjmp.h. Include systime.h instead.

4319 All uses changed to store the new value.
4320 (handle_profiler_signal): Rename from sigprof_handler_1,
4321 for consistency with other handlers. Do not check whether
4322 cpu_log is a hash-table if garbage collecting, since it
4323 doesn't matter in that case.

4325 for consistency with other handlers.
4326 (setup_cpu_timer): New function, with much of what used to be in
4327 Fprofiler_cpu_start. Check for out-of-range argument.
4328 Prefer timer_settime if available, and prefer
4329 thread cputime clocks, then process cputime clocks, then
4330 monotonic clocks, to the old realtime clock. Use make_timeval
4331 to round more-correctly when falling back to setitimer.
4332 (Fprofiler_cpu_start): Use it.
4333 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4334 Don't assume that passing NULL as the 2nd argument of setitimer

4337 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4338 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4339 non-fatal signal handlers. Ignore SIGPROF on startup.
4340 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4341 in profiler.c, since sysdep.c now uses it.
4343 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4399 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4400 Since this stuff is now private to charset.c, there's no need for
4401 a public macro and no need to inline by hand.

4475 (sys_kill): Improve commentary.
4477 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4478 consistency with a signature of a signal handler. All callers
4480 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4481 install term_ntproc as a signal handler for SIGABRT, as that
4482 should be done by the dumped Emacs.

4601 ($(BLD)/w32xfns.$(O)): Update dependencies.
4603 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4605 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4606 fatal_error_backtrace.
4608 * w32proc.c (sys_kill): Undo last change: don't do anything when
4609 invoked to deliver SIGABRT to our own process. This is now
4610 handled by emacs_raise.
4612 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4614 * w32term.c (w32_read_socket): Remove leftover reference to
4615 interrupt_input_pending.
4617 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4619 Do not use SA_NODEFER.
4620 Problem reported by Dani Moncayo in
4621 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4623 * sysdep.c (emacs_abort): Do not reset signal handler.
4624 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4625 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4626 wanted even on POSIXish hosts, and it doesn't work on Windows.
4628 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4630 * xterm.c (x_term_init): Call fixup_locale before and after calling
4631 gtk_init (Bug#12392).
4633 2012-09-23 Chong Yidong <cyd@gnu.org>
4635 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4636 Vdynamic_library_alist.
4638 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4639 (Fgnutls_available_p): Caller changed.
4641 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4642 (Flibxml_parse_xml_region): Likewise.
4644 * dispextern.h (struct image_type): Remove arg from init function.
4646 * image.c (Finit_image_library, lookup_image_type)
4647 (define_image_type): Remove now-unneeded second arg.
4648 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4649 (init_tiff_functions, init_gif_functions, init_svg_functions):
4650 Arglist and w32_delayed_load calling convention changed.
4651 (gs_type): Remove init_gs_functions; there is no such function.
4652 (valid_image_p, make_image): Fix caller to lookup_image_type.
4654 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4656 Simplify and avoid signal-handling races (Bug#12471).
4658 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4659 Avoid recursive loop if there's a fatal error in the function itself.
4660 * atimer.c (pending_atimers):
4661 * blockinput.h: Don't include "atimer.h"; no longer needed.
4662 (interrupt_input_pending): Remove. All uses removed.
4663 pending_signals now counts both atimers and ordinary interrupts.
4664 This is less racy than having three separate pending-signal flags.
4665 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4667 Rename from their upper-case counterparts BLOCK_INPUT,
4668 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4669 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4670 This makes it easier to access volatile variables more accurately.
4671 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4672 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4673 that's more reliable if the code is buggy and sets
4674 interrupt_input_blocked to a negative value. All uses changed.
4675 * atimer.c (deliver_alarm_signal):
4676 Remove. No need to deliver this to the parent; any thread can
4677 handle this signal now. All uses replaced by underlying handler.
4678 * atimer.c (turn_on_atimers):
4679 * dispnew.c (handle_window_change_signal):
4680 * emacs.c (handle_danger_signal):
4681 * keyboard.c (kbd_buffer_get_event):
4682 Don't reestablish signal handler; not needed with sigaction.
4683 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4685 Rework to avoid unnecessary accesses to volatile variables.
4686 (UNBLOCK_INPUT_TO): Now a function.
4687 (totally_unblock_input, unblock_input): New decls.
4688 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4689 (init_data): Remove. Necessary stuff now done in init_signal.
4690 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4691 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4692 (fatal_error_code): Remove; no longer needed.
4693 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4694 it doesn't always backtrace. All uses changed. No need to reset
4695 signal to default, since sigaction and/or die does that for us now.
4696 Use emacs_raise (FOO), not kill (getpid (), FOO).
4697 (main): Check more-accurately whether we're dumping.
4698 Move fatal-error setup to sysdep.c
4699 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4700 * gtkutil.c (xg_get_file_name, xg_get_font):
4701 Remove no-longer-needed signal-mask manipulation.
4702 * keyboard.c, process.c (POLL_FOR_INPUT):
4703 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4704 * keyboard.c (read_avail_input): Remove.
4705 All uses replaced by gobble_input.
4706 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4707 (kbd_buffer_store_event_hold, gobble_input):
4708 (record_asynch_buffer_change) [USABLE_SIGIO]:
4709 (store_user_signal_events):
4710 No need to mess with signal mask.
4711 (gobble_input): If blocking input and there are terminals, simply
4712 set pending_signals to 1 and return. All hooks changed to not
4713 worry about whether input is blocked.
4714 (process_pending_signals): Clear pending_signals before processing
4715 them, in case a signal comes in while we're processing.
4716 By convention callers now test pending_signals before calling us.
4717 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4718 New functions, to support changes to blockinput.h.
4719 (handle_input_available_signal): Now extern.
4720 (reinvoke_input_signal): Remove. All uses replaced by
4722 (quit_count): Now volatile, since a signal handler uses it.
4723 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4724 All callers changed. Block SIGINT only if not already blocked.
4725 Clear sigmask reliably, even if Fsignal returns, which it can.
4726 Omit unnecessary accesses to volatile var.
4727 (quit_throw_to_read_char): No need to restore sigmask.
4728 * keyboard.c (gobble_input, handle_user_signal):
4729 * process.c (wait_reading_process_output):
4730 Call signal-handling code rather than killing ourselves.
4731 * lisp.h: Include <float.h>, for...
4732 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4733 (pending_signals): Now volatile.
4734 (syms_of_data): Now const if IEEE floating point.
4735 (handle_input_available_signal) [USABLE_SIGIO]:
4736 (terminate_due_to_signal, record_child_status_change): New decls.
4737 * process.c (create_process): Avoid disaster if memory is exhausted
4738 while we're processing a vfork, by tightening the critical section
4740 (send_process_frame, process_sent_to, handle_pipe_signal)
4741 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4743 (send_process): No need for setjmp/longjmp any more, since the
4744 SIGPIPE stuff is now gone. Instead, report an error if errno
4746 (record_child_status_change): Now extern. PID and W are now args.
4747 Return void, not bool. All callers changed.
4748 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4749 Remove. All uses removed. This bug should be fixed now in a
4751 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4752 and record the child status change directly. This avoids the
4753 need to futz with the signal mask.
4754 (process_fatal_action): Move here from emacs.c.
4755 (emacs_sigaction_flags): New function, containing
4756 much of what used to be in emacs_sigaction_init.
4757 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4758 caught by emacs, to make races less likely.
4759 (deliver_process_signal): Rename from handle_on_main_thread.
4761 (BACKTRACE_LIMIT_MAX): Now at top level.
4762 (thread_backtrace_buffer, threadback_backtrace_pointers):
4764 (deliver_thread_signal, deliver_fatal_thread_signal):
4765 New functions, for more-accurate delivery of thread-specific signals.
4766 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4767 (deliver_arith_signal): Handle in this thread, not
4768 in the main thread, since it's triggered by this thread.
4769 (maybe_fatal_sig): New function.
4770 (init_signals): New arg DUMPING so that we can be more accurate
4771 about whether we're dumping. Caller changed.
4772 Treat thread-specific signals differently from process-general signals.
4773 Block all signals while handling fatal error; that's safer.
4774 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4776 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4777 Ignore SIGPIPE unless batch.
4778 (emacs_backtrace): Output backtrace for the appropriate thread,
4779 which is not necessarily the main thread.
4780 * syssignal.h: Include <stdbool.h>.
4781 (emacs_raise): New macro.
4782 * xterm.c (x_connection_signal): Remove; no longer needed
4783 now that we use sigaction.
4784 (x_connection_closed): No need to mess with sigmask now.
4785 (x_initialize): No need to reset SIGPIPE handler here, since
4786 init_signals does this for us now.
4788 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4790 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4791 background rect may be larger (Bug#12245).
4793 2012-09-23 Chong Yidong <cyd@gnu.org>
4795 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4797 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4799 * .gdbinit: Just stop at fatal_error_backtrace.
4800 See Stefan Monnier's request in
4801 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4802 Remove no-longer-used query of system type.
4804 2012-09-22 Chong Yidong <cyd@gnu.org>
4806 * search.c (Freplace_match): Doc fix (Bug#12325).
4808 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4810 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4811 (Fline_end_position): Doc fix.
4813 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4815 2012-09-22 Chong Yidong <cyd@gnu.org>
4817 * dispextern.h (struct image_type): Add new slot, storing a type
4818 initialization function.
4820 * image.c (define_image_type): Call the image initializer function
4821 if it is defined. Arguments and return value changed.
4822 (valid_image_p, make_image): Callers changed.
4823 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4824 (gif_type, imagemagick_type, svg_type, gs_type):
4825 Add initialization functions.
4826 (Finit_image_library): Call lookup_image_type.
4827 (CHECK_LIB_AVAILABLE): Macro deleted.
4828 (lookup_image_type): Call define_image_type here, rather than via
4829 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4830 (syms_of_image): Move define_image_type calls for xbm_type and
4831 pbm_type to lookup_image_type.
4833 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4835 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4836 'idle_timers' from here ...
4837 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4838 lists, to avoid infloops when the timer does something stupid,
4839 like reinvoke itself with the same or smaller time-out.
4842 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4844 * window.c (Fsplit_window_internal): Handle only Qt value of
4845 Vwindow_combination_limit separately.
4846 (Qtemp_buffer_resize): New symbol.
4847 (Vwindow_combination_limit): New default value.
4850 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4852 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4853 the new overlay string. (Bug#10159)
4855 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4857 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4858 or that fprintf is async-signal-safe. POSIX doesn't require
4861 2012-09-22 Chong Yidong <cyd@gnu.org>
4863 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4866 2012-09-22 Kenichi Handa <handa@gnu.org>
4868 * composite.c (composition_reseat_it): Handle the case that a
4869 grapheme cluster is not covered by a single font (Bug#12352).
4871 2012-09-21 Chong Yidong <cyd@gnu.org>
4873 * image.c (define_image_type): Avoid adding duplicate types to
4874 image_types (Bug#12463). Suggested by Jörg Walter.
4876 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4878 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4879 (print_load_command_name): Add case LC_DATA_IN_CODE.
4880 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4882 2012-09-21 Glenn Morris <rgm@gnu.org>
4884 * eval.c (Frun_hook_with_args_until_success)
4885 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4887 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4889 * fileio.c (Ffile_selinux_context): Only call freecon when
4890 lgetfilecon succeeded.
4891 (Fset_file_selinux_context): Likewise. (Bug#12444)
4893 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4895 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4896 reordering, locate the cursor by calling set_cursor_from_row; if
4897 that fails, clear the desired glyph matrix before returning a
4898 failure indication to the caller. Fixes leaving garbled display
4899 when fast scrolling with a down-key. (Bug#12403)
4900 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4901 scrolling through multibyte text.
4903 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4905 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4906 calling mark_vectorlike since that's the one that marks the window.
4907 (mark_discard_killed_buffers): Mark the final cdr.
4908 * window.h (struct window): Move prev/next_buffers to the
4909 non-standard fields.
4910 * window.c (make_window): Initialize prev/next_buffers manually.
4912 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4914 Omit unused arg EXPECTED from socket hooks.
4915 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4916 * nsterm.m (ns_term_init):
4917 * termhooks.h (struct terminal.read_socket_hook):
4918 * w32inevt.c (w32_console_read_socket):
4919 * w32term.c (w32_read_socket):
4920 * xterm.c (XTread_socket):
4921 Omit unused arg EXPECTED. All callers changed.
4922 (store_user_signal_events): Return void, not int, since callers no
4923 longer care about the return value. All uses changed.
4925 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4927 * w32gui.h (XParseGeometry): Do not declare.
4929 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4931 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4932 Ignore 'expected'. See Eli Zaretskii in
4933 <http://bugs.gnu.org/12471#8> (last line).
4935 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4936 (XParseGeometry): Now static. Substitute extremal values for
4937 values that are out of range.
4939 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4941 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4943 * nsfns.m (XParseGeometry): Remove.
4944 (Fx_create_frame): Call x_set_offset to correctly interpret
4945 top_pos in geometry.
4947 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4948 (Fx_parse_geometry): If there is a space in string, call
4949 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4951 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4953 * search.c (scan_buffer): Use character positions in calls to
4954 region_cache_forward and region_cache_backward, not byte
4955 positions. (Bug#12196)
4957 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4958 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4960 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4961 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4962 emacs_blocked_malloc, now deleted.
4964 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4966 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4967 The workaround was for improving performance on Solaris 2.4, but
4968 is getting in the way now. Emacs will still work if someone is
4969 still running Solaris 2.4 in a museum somewhere; Sun dropped
4970 support for Solaris 2.4 in 2003.
4971 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4972 * process.c (create_process) [HAVE_WORKING_VFORK]:
4973 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4974 since Emacs no longer uses vfork on that platform.
4976 2012-09-17 Glenn Morris <rgm@gnu.org>
4978 * emacs.c: Use COPYRIGHT.
4980 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4982 Remove configure's --without-sync-input option (Bug#12450).
4983 When auditing signal-handling in preparation for cleaning it up,
4984 I found that SYNC_INPUT has race conditions and would be a real
4985 pain to fix. Since it's an undocumented and deprecated
4986 configure-time option, now seems like a good time to remove it.
4987 Also see <http://bugs.gnu.org/11080#16>.
4988 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4989 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4990 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4991 (malloc_hysteresis):
4992 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4993 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4994 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4995 (dont_register_blocks, bytes_used_when_reconsidered)
4996 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4997 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4998 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4999 Remove. All uses removed.
5000 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5001 implementation, one that depends on whether the new macro
5002 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5004 * atimer.c (run_timers, handle_alarm_signal):
5005 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5006 (handle_async_input, process_pending_signals)
5007 (handle_input_available_signal, init_keyboard):
5008 * nsterm.m (ns_read_socket):
5009 * process.c (wait_reading_process_output):
5010 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5011 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5013 * xterm.c (XTread_socket):
5015 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5016 * eval.c (handling_signal): Remove. All uses removed.
5017 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5018 All uses replaced with the SYNC_INPUT version.
5019 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5021 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5024 * font.c (Ffont_shape_gstring): Remove unused local.
5026 2012-09-16 Glenn Morris <rgm@gnu.org>
5028 * Makefile.in (clean): No longer run nextstep's clean.
5030 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5032 (ns-app): Move here from ns.mk, and simplify.
5033 (clean): Simplify nextstep entry.
5034 * ns.mk: Remove file.
5036 2012-09-17 Kenichi Handa <handa@gnu.org>
5038 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5039 not covert the last few charactes.
5041 2012-09-16 Kenichi Handa <handa@gnu.org>
5043 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5044 here, but just check the validity of glyphs in the glyph-string.
5046 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5048 * window.c (Fwindow_parameter, Fset_window_parameter):
5049 Accept any window as argument (Bug#12452).
5051 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5053 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5054 to ns_term_init to avoid memory leak.
5056 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5057 explicit retain/release.
5058 (ns_term_init): Only allow one display. Initialize outerpool and
5061 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5063 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5064 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5065 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5066 the Microsoft problem in a different way, by altering ../nt/config.nt.
5068 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5083 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5084 by lisp.h. This completes removal of setjmp.h inclusion
5085 erroneously announced in the previous commit. (Bug#12446)
5087 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5090 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5091 not defined as a macro. The latter happens on MS-Windows.
5094 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5096 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5097 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5098 Some instances of '#include <setjmp.h>' removed, if the
5099 only reason for the instance was because "lisp.h" was included.
5100 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5101 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5102 and _longjmp with the new symbols. Emacs already uses _setjmp if
5103 available, so this change affects only POSIXish hosts that have
5104 sigsetjmp but not _setjmp, such as some versions of Solaris and
5105 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5106 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5107 (png_load_body) [HAVE_PNG]:
5108 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5109 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5110 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5111 since PNG requires jmp_buf. This is the only exception to the
5112 general rule that we now use sys_setjmp and sys_longjmp.
5113 This exception is OK since this code does not change the signal
5114 mask or longjmp out of a signal handler.
5116 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5118 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5119 Include "syssignal.h", for 'main_thread'.
5121 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5123 Avoid out-of-range marker position (Bug#12426).
5124 * insdel.c (replace_range, replace_range_2):
5125 Adjust markers before overlays, as suggested by comments.
5126 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5127 Remove redundant check before calling offset_intervals.
5129 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5131 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5132 current buffer (Bug#12387).
5134 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5136 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5138 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5140 Use a more backwards-compatible timer format (Bug#12430).
5141 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5142 vector element, not from the 4th, since PSECS is now at the end.
5143 (Fcurrent_idle_time): Doc fix.
5145 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5147 Function to mark objects and remove killed buffers at once.
5148 * alloc.c (discard_killed_buffers): Rename to ...
5149 (mark_discard_killed buffers) ... new name. Add marking
5150 of remaining objects. Fix comment. Adjust users.
5151 (mark_object): Do not touch frame buffer lists here.
5152 * frame.c (delete_frame): Reset frame buffer lists here.
5154 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5156 Better workaround for GNOME bug when --enable-gcc-warnings.
5157 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5158 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5159 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5161 Simplify SIGIO usage (Bug#12408).
5162 The code that dealt with SIGIO was crufty and confusing, e.g., it
5163 played tricks like "#undef SIGIO" but these tricks were not used
5164 consistently. Simplify mostly by not #undeffing standard symbols,
5165 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5166 or not as we please) rather than "defined SIGIO" (standard symbol
5167 that we probably shouldn't #undef).
5168 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5169 Modules that need it can include it.
5170 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5171 * dispextern.h (ignore_sigio): New decl.
5172 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5173 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5174 * emacs.c (shut_down_emacs):
5175 * keyboard.c (kbd_buffer_store_event_hold):
5176 Use ignore_sigio rather than invoking 'signal' directly.
5177 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5179 (FIONREAD, SIGIO): Do not #undef.
5180 (tty_read_avail_input): Use #error rather than a syntax error.
5181 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5182 for I_PIPE, used by SETUP_SLAVE_PTY.
5183 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5184 * sysdep.c (croak): Remove; no longer needed. This bit of
5185 temporary code, with Fred N. Fish's comment that it's temporary,
5186 has been in Emacs since at least 1992!
5187 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5188 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5189 * syssignal.h (croak): Remove decl.
5190 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5191 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5192 now that we're termios-only.
5193 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5194 * term.c (dissociate_if_controlling_tty): Use #error rather than
5197 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5198 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5199 to work around GNOME bug 683906.
5200 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5201 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5202 This works around GCC bug 54561.
5204 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5206 More fixes for 'volatile' and setjmp/longjmp.
5207 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5208 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5209 (png_load_body) [HAVE_PNG]:
5210 (jpeg_load_body) [HAVE_JPEG]:
5211 New function, with most of the old parent function's body.
5212 (png_load) [HAVE_PNG]:
5213 (jpeg_load) [HAVE_JPEG]:
5214 Invoke the new function, to avoid longjmp munging our locals.
5215 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5216 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5217 longjmp is passed 2, as the C standard doesn't guarantee this.
5218 Instead, store the failure code into mgr->failure_code.
5220 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5222 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5223 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5224 (syms_of_keyboard): Remove support for unread-command-char.
5226 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5228 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5229 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5230 violation. (Bug#12426)
5232 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5234 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5236 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5238 * eval.c: Add `inhibit-debugger'.
5239 (Qinhibit_debugger): New symbol.
5240 (call_debugger): Bind it instead of Qdebug_on_error.
5241 (maybe_call_debugger): Test Vinhibit_debugger.
5242 (syms_of_eval): Define inhibit-debugger.
5243 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5244 (syms_of_xdisp): Remove inhibit-debug-on-message.
5246 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5248 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5249 If a nonvolatile local variable is written before a _longjmp to
5250 the frame containing the variable, and is read after the _longjmp,
5251 the value read is indeterminate. Some local variables of type
5252 'struct handler' and 'struct catchtag' are used in this way, so
5253 mark each of their slots as volatile if the slot can be set before
5254 _longjmp and read afterwards.
5255 * lisp.h (struct handler): var and chosen_clause are now volatile.
5256 (struct catchtag): val, next, and pdlcount are now volatile.
5258 * bidi.c (bidi_push_it, bidi_pop_it):
5259 * fns.c (copy_hash_table):
5260 * image.c (define_image_type):
5261 * keyboard.c (kbd_buffer_store_event_hold):
5262 * process.c (Fprocess_send_eof):
5263 * xfaces.c (x_create_gc) [HAVE_NS]:
5264 * xgselect.c (xg_select):
5265 Prefer assignment to memcpy when either will do.
5267 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5268 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5269 time an item is removed. No need to mark this function 'inline';
5270 the compiler knows better than we do.
5272 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5274 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5275 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5276 to change_frame_size (Bug#12388).
5277 (windowDidResize:): Pass YES to updateFrameSize.
5279 * nsterm.h: Add delay parameter to updateFrameSize.
5281 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5283 Discard killed buffers from deleted window and frame objects.
5284 This reduces an amount of references to killed buffers and
5285 helps GC to reclaim them faster.
5286 * alloc.c (discard_killed_buffers): New function.
5287 (mark_object): Use it for deleted windows and frames.
5288 (mark_object): If symbol's value is set up for a killed buffer
5289 or deleted frame, restore its global binding.
5290 * data.c (swap_in_global_binding): Add GC notice.
5291 (swap_in_symval_forwarding): Use convenient set_blv_where.
5292 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5293 * window.h: ... to here.
5295 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5297 Convenient macro to check whether the buffer is live.
5298 * buffer.h (BUFFER_LIVE_P): New macro.
5299 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5300 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5302 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5304 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5305 composition cases (Bug#12364).
5307 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5308 overhang of succeeding glyphs overlapping box cursor.
5310 * w32term.c (x_draw_glyph_string): Likewise.
5312 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5314 Simplify, document, and port floating-point (Bug#12381).
5315 The porting part of this patch fixes bugs on non-IEEE platforms
5316 with frexp, ldexp, logb.
5317 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5319 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5320 support, by removing commented-out code and briefly listing the
5321 C89 functions excluded. The commented-out stuff was confusing
5322 maintenance, e.g., we thought we needed cbrt but it was commented out.
5323 (logb): Remove decl; no longer needed.
5324 (isfinite): New macro, if not already supplied.
5325 (isnan): Don't replace any existing macro.
5326 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5327 are present on all C89 platforms.
5328 (Ffrexp): Do not special-case zero, as frexp does the right thing
5330 (Flogb): Do not use logb, as it doesn't have the desired meaning
5331 on hosts that use non-base-2 floating point. Instead, stick with
5332 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5333 frexp, to avoid getting an unspecified result.
5335 * xdisp.c (Qinhibit_debug_on_message): Now static.
5337 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5339 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5340 NSBezierPath (Bug#12131).
5342 2012-09-10 Chong Yidong <cyd@gnu.org>
5344 * fns.c (Fdelq, Fdelete): Doc fix.
5346 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5348 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5349 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5351 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5353 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5354 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5357 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5359 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5360 left fringe if the window has a left margin. This avoids leaving
5361 traces of the cursor because its leftmost pixel is not drawn over.
5363 * dispnew.c (update_window_line): When the left margin area of a
5364 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5365 that screen line. (Bug#12277)
5367 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5369 Assume C89 or later for math functions (Bug#12381).
5370 This simplifies the code, and makes it a bit smaller and faster,
5371 and (most important) makes it easier to clean up signal handling
5372 since we can stop worring about floating-point exceptions in
5373 library code. That was a problem before C89, but the problem
5374 went away many years ago on all practical Emacs targets.
5375 * data.c, image.c, lread.c, print.c:
5376 Don't include <math.h>; no longer needed.
5377 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5378 might be autoconfigured, as that never happens.
5380 * doprnt.c (DBL_MAX_10_EXP):
5381 * print.c (DBL_DIG):
5382 Remove. C89 or later always defines these.
5383 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5384 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5385 (arith_error, domain_error, domain_error2):
5386 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5387 no longer needed -- we simply return what C returns. All uses removed.
5388 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5390 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5391 Remove. All uses expanded, as these macros are no longer used
5392 more than once and are now more trouble than they're worth.
5393 (Ftan): Use tan, not sin / cos.
5394 (Flogb): Assume C89 frexp.
5395 (fmod_float): Assume C89 fmod.
5396 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5397 (init_floatfns): Remove. All uses removed.
5399 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5401 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5402 compositeToPoint for OSX < 10.6 (Bug#12390).
5404 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5406 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5407 This produces more-accurate results.
5409 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5411 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5412 changes (Bug#12088).
5414 2012-09-08 Chong Yidong <cyd@gnu.org>
5416 * syntax.c (Fstring_to_syntax): Doc fix.
5418 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5420 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5421 in the internal border.
5422 (x_set_window_size): Remove static variables and their usage.
5423 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5424 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5425 Remove fringe/internal border adjustment (Bug#11052).
5426 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5427 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5428 (ns_fix_rect_ibw): Remove.
5429 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5430 (ns_dumpglyphs_box_or_relief): Ditto.
5431 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5433 (ns_dumpglyphs_image): Ditto.
5434 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5436 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5437 their usage. Add fringe_extended_p and its use as in other terms.
5438 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5439 scroll bar was removed.
5440 (updateFrameSize): New function.
5441 (windowDidResize): Move code to updateFrameSize and call it.
5443 * nsterm.h (EmacsView): Add updateFrameSize.
5445 2012-09-07 Chong Yidong <cyd@gnu.org>
5447 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5449 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5451 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5453 More signal-handler cleanup (Bug#12327).
5454 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5455 Problem introduced when merging patches. Noted by Eli Zaretskii in
5456 <http://bugs.gnu.org/12327#67>.
5457 * floatfns.c: Comment fix.
5458 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5459 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5460 and anyway the declaration is harmless even if SIGDANGER is not defined.
5461 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5462 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5463 source files not surprisingly expected syssignal.h to define, or
5464 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5465 Include <sys/ioctl.h>, for FIONREAD.
5466 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5467 This eliminates a problem whereby other files mysteriously had
5468 to include "syssignal.h" before including "systty.h" if they
5469 wanted to use "#ifdef SIGIO".
5471 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5473 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5475 * w32.c (sigemptyset): Empty the set.
5476 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5478 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5480 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5482 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5483 (mark_object): Likewise for frame objects.
5485 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5487 * syssignal.h (handle_on_main_thread): Always declare,
5488 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5489 This ports to platforms without HAVE_PTHREAD.
5491 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5493 Signal-handler cleanup (Bug#12327).
5494 Emacs's signal handlers were written in the old 4.2BSD style with
5495 sigblock and sigmask and so forth, and this led to some
5496 inefficiencies and confusion. Rewrite these to use
5497 pthread_sigmask etc. without copying signal sets around. Also,
5498 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5499 'signal', and instead use functions that do not attempt to take
5500 over the system name space. This patch causes Emacs's text
5501 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5502 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5503 Do not include <signal.h> or "syssignal.h", as these
5504 modules do not use signals.
5505 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5506 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5507 Do not include <signal.h>, as "syssignal.h" does that for us now.
5508 * atimer.c (sigmask_atimers): New function.
5509 (block_atimers, unblock_atimers): New functions,
5510 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5512 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5513 no longer needed here.
5514 * emacs.c (main): Inspect existing signal handler with sigaction,
5515 so that there's no need to block and unblock SIGHUP.
5516 * sysdep.c (struct save_signal): New member 'action', replacing
5517 old member 'handler'.
5518 (save_signal_handlers, restore_signal_handlers):
5519 Use sigaction instead of 'signal' to save and restore.
5520 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5521 New function. All users of 'signal' modified to use set_sighandler
5522 if they're writeonly, and to use sys_signal if they're read+write.
5523 (emacs_sigaction_init, forwarded_signal): New functions.
5524 (sys_signal): Remove. All uses replaced by calls to sigaction
5525 and emacs_sigaction_init, or by direct calls to 'signal'.
5526 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5527 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5528 all uses replaced by pthread_sigmask etc. calls.
5529 * syssignal.h: Include <signal.h>.
5530 (emacs_sigaction_init, forwarded_signal): New decls.
5531 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.

5534 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5535 (sigblock, sigunblock, sigfree):
5536 (sigsetmask) [!defined sigsetmask]:
5537 Remove. All uses replaced by pthread_sigmask.
5538 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5539 no longer need to be replaced, and its typical old uses
5540 are now done via emacs_sigaction_init and sigaction.
5541 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5542 (sys_sigdel): Remove; unused.
5543 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5545 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5547 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5548 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5550 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5552 Explicitly mark buffer_defaults and buffer_local_symbols.
5553 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5554 mark_local_symbols here.
5555 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5556 since special buffers aren't marked here any more.
5557 (allocate_buffer): Chain new buffer with all_buffers here...
5558 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5560 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5561 (syms_of_buffer): Remove staticpro of the above.

5565 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5567 Use bool for booleans in font-related modules.
5568 * font.c (font_intern_prop, font_style_to_value)
5569 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5570 (generate_otf_features, font_check_otf_features, font_check_otf)
5571 (font_match_p, font_list_entities, font_at):
5572 * fontset.c (fontset_id_valid_p, reorder_font_vector
5573 (fontset_find_font, Fset_fontset_font)
5574 (face_suitable_for_char_p) [0]:
5575 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5576 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5577 (m17n_flt_initialized, ftfont_shape_by_flt):
5578 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5579 * nsfont.m (nsfont_draw):
5580 * w32font.c (w32font_draw):
5581 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5582 Use bool for booleans.
5583 * font.h: Adjust to above API changes.
5584 (struct font, struct font_driver, struct font_driver_list):
5585 Use bool for booleans.
5586 (struct font): Remove useless member encoding_type.
5588 * fontset.c, xftfont.c: Omit unnecessary static decls.
5590 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5592 * alloc.c (mark_object): Revert window marking code
5593 since it's unsafe for the Fset_window_configuration.
5595 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5597 Fix race conditions with signal handlers and errno (Bug#12327).
5598 Be more systematic about preserving errno whenever a signal
5599 handler returns, even if it's not in the main thread. Do this by
5600 renaming signal handlers to distinguish between signal delivery
5601 and signal handling. All uses changed.
5602 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5603 * data.c (deliver_arith_signal): Rename from arith_error.
5604 * dispnew.c (deliver_window_change_signal): Rename from
5605 window_change_signal.
5606 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5607 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5608 * keyboard.c (deliver_input_available_signal): Rename from
5609 input_available_signal.
5610 (deliver_user_signal): Rename from handle_user_signal.
5611 (deliver_interrupt_signal): Rename from interrupt_signal.
5612 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5613 (deliver_child_signal): Rename from sigchld_handler.
5614 * atimer.c (handle_alarm_signal):
5615 * data.c (handle_arith_signal):
5616 * dispnew.c (handle_window_change_signal):
5617 * emacs.c (handle_fatal_signal, handle_danger_signal):
5618 * keyboard.c (handle_input_available_signal):
5619 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5620 * process.c (handle_pipe_signal, handle_child_signal):
5621 New functions, with the actual signal-handling code taken from the
5622 original respective signal handlers, sans the sporadic attempts to
5623 preserve errno, since that's now done by handle_on_main_thread.
5624 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5625 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5626 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5628 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5629 Move initialization of main_thread to sysdep.c's init_signals.
5630 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5631 our usage, and simplifies the mainline code.
5632 (record_child_status_change): New static function, as a helper
5633 for handle_child_signal, and with most of the old child handler's
5635 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5636 (handle_child_signal): Use the above.
5637 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5638 Moved here from emacs.c.
5639 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5640 code moved here from emacs.c's main function.
5641 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5642 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5643 This lets callers save and restore errno properly.
5645 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5647 Remove redundant or unused things here and there.
5648 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5649 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5650 * editfns.c (Fcompare_buffer_substrings): Likewise.
5651 * frame.h (struct terminal, struct font_driver_list):
5652 Remove redundant declarations.
5653 * window.h (Qleft, Qright): Likewise.
5655 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5657 Do not mark objects from deleted buffers, windows and frames.
5658 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5659 (mark_object): Likewise for windows and frames.
5661 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5663 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5664 buffer_defaults and buffer_local_symbols as valid objects.
5665 Return special value to denote them.
5667 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5669 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5670 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5671 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5672 (file_name_absolute_p, Fsubstitute_in_file_name):
5673 (check_executable, check_writable, Ffile_accessible_directory_p)
5674 (Fset_file_selinux_context, Fdefault_file_modes)
5675 (Finsert_file_contents, choose_write_coding_system)
5676 (Fwrite_region, build_annotations, a_write, e_write)
5678 * filelock.c (boot_time_initialized, get_boot_time)
5679 (get_boot_time_1, lock_file_1, within_one_second):
5680 * floatfns.c (in_float):
5681 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5682 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5683 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5684 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5685 * window.c (compare_window_configurations):
5686 Use bool for booleans.
5687 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5688 (Fdefault_file_modes): Now mode_t, not int, for modes.
5689 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5690 (internal_delete_file): Now returns void, not a (boolean) int,
5691 since nobody was looking at the return value.
5692 * lisp.h, window.h: Adjust to above API changes.
5694 * xdisp.c (set_message): Simplify and reindent last change.
5696 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5698 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5700 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5702 * eval.c (call_debugger): Make the function non-static so that we
5703 can call it from set_message.
5705 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5706 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5708 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5710 Give more-useful info on a fatal error (Bug#12328).
5711 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5712 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5713 of doing the work ourselves.
5714 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5715 do most of the work.
5716 (fatal_error_backtrace): New function, taken from the guts
5717 of the old fatal_error_signal, but with a new option to output
5719 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5720 info about the signal than just its number.
5721 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5722 * sysdep.c: Include <execinfo.h>
5723 (emacs_backtrace): New function, taken partly from the previous
5724 code of the 'die' function.
5725 (emacs_abort): Call fatal_error_backtrace rather than abort.
5727 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5729 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5730 eager (load-time) macro-expansion.
5731 * lisp.mk (lisp): Add macroexp.
5733 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5735 Simplify redefinition of 'abort' (Bug#12316).
5736 Do not try to redefine the 'abort' function. Instead, redo
5737 the code so that it calls 'emacs_abort' rather than 'abort'.
5738 This removes the need for the NO_ABORT configure-time macro
5739 and makes it easier to change the abort code to do a backtrace.
5740 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5741 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5742 Remove; sysdep.c's emacs_abort now takes its place.
5743 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5744 'abort' changed to use 'emacs_abort'.
5745 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5746 (abort) [!defined abort]: Rename to ...
5747 (emacs_abort): ... new name.
5748 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5749 the place of the old 'abort' in emacs.c.
5750 * w32.c, w32fns.c (abort): Do not #undef.
5751 * w32.c (emacs_abort): Rename from w32_abort.
5753 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5755 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5756 offsets[j].dv, since the y axis of the screen coordinates points
5757 down, while the y axis of the font definition coordinates points
5758 up. This fixes display of Arabic diacritics such as KASRA and
5759 KASRATAN. (Bug#11860)
5761 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5763 Be more systematic about _setjmp vs setjmp.
5764 * alloc.c (test_setjmp, mark_stack):
5765 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5766 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5767 (png_load, my_error_exit, jpeg_load):
5768 * process.c (send_process_trap, send_process):
5769 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5770 The underscored versions are up to 30x faster on some hosts.
5771 Formerly, the code used setjmp+longjmp sometimes and
5772 _setjmp+_longjmp at other times, with no particular reason to
5773 prefer setjmp+longjmp.
5775 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5777 Fix minor problem found by static checking.
5778 * buffer.c (Fdelete_all_overlays): Return nil.
5780 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5782 * buffer.c (Fdelete_all_overlays): New function.
5784 2012-09-03 Chong Yidong <cyd@gnu.org>
5786 * gtkutil.c: Add extern decl for Qxft.
5788 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5790 * emacs.c, eval.c: Use bool for boolean.
5791 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5792 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5793 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5794 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5795 (main, decode_env_path, Fdaemon_initialized):

5797 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5798 (maybe_call_debugger, Fbacktrace):
5799 * process.c (read_process_output, exec_sentinel):
5800 Use bool for booleans.
5801 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5802 All callers changed.
5803 * eval.c (interactive_p): Omit always-true boolean argument
5804 EXCLUDE_SUBRS_P. All callers changed.
5805 * dispextern.h, lisp.h: Reflect above API changes.
5806 * firstfile.c (dummy): Use the address of 'main', whose signature
5807 won't change, instead of the address of 'initialize', whose
5808 signature just changed from int to bool.
5809 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5810 * msdos.c (fatal_error_in_progress): ... from here.
5811 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5813 (redisplay_internal, unwind_redisplay): Simply clear
5814 REDISPLAYING_P when unwinding, instead of saving its previous,
5815 always-false value and then restoring it.
5817 Clean up some extern decls.
5818 Mostly, this hoists extern decls out of .c files and into .h files.
5819 That way, we're more likely to catch errors if the interfaces change.
5820 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5821 declare xg_mark_data.
5822 * dispextern.h (x_frame_parm_handlers):
5824 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5825 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5826 (Qultra_bold, Qoblique, Qitalic):
5827 Move extern decl here from .c file.
5828 * alloc.c (xg_mark_data) [USE_GTK]:
5830 * eval.c (Qlexical_binding):
5831 * fns.c (time) [!HAVE_UNISTD_H]:

5837 * process.c (QCfamily, QCfilter):
5838 * widget.c (free_frame_faces):
5839 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5840 * xfont.c (x_clear_errors):
5841 * xterm.c (x_frame_parm_handlers):
5842 Remove now-redundant extern decls.
5843 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5844 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5846 * xfaces.c: Remove unnecessary static decls.
5847 * xterm.c (updating_frame): Remove decl of nonexistent object.
5849 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5850 when building globals.h, as the objects that are not built on
5851 this host are not needed to compile C files on this host.
5853 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5855 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5857 * frame.h: Add missing prototype for x_wm_set_size_hint.
5859 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5863 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5864 (Fsubstitute_command_keys):

5867 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
5868 (format_time_string, general_insert_function)
5869 (make_buffer_string, make_buffer_string_both)
5870 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5882 (set_intervals_multibyte_1, set_intervals_multibyte):
5883 * keyboard.c (decode_timer):
5884 Use bool for boolean.
5885 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5886 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5888 2012-09-02 Chong Yidong <cyd@gnu.org>
5890 * keymap.c (push_key_description): Print M-TAB as C-M-i
5893 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5895 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5896 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5897 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5901 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5903 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5905 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5906 more than one grapheme cluster passed to the shaper: compute the
5907 offset adjustment values separately for each cluster. (Bug#11860)
5909 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5910 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5911 about implicit conversions from integer to pointer.
5913 2012-09-01 Daniel Colascione <dancol@dancol.org>
5915 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

6230 Special MEM_TYPE_SPARE to denote reserved memory.
6231 * alloc.c (enum mem_type): New memory type.
6232 (refill_memory_reserve): Use new type for spare memory.

6268 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6269 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6270 are all boolean, so make them single-bit bitfields.
6272 * lisp.h (ASET): Remove attempt to detect side effects.
6273 It was meant to be temporary and it often doesn't work,
6274 because when IDX has side effects the behavior of IDX==IDX
6275 is undefined. See Stefan Monnier in
6276 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6278 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6281 (FUNCTIONP): Use it.

6286 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6287 as that's faster and simpler than static storage. Don't bother
6288 with the g_main_context_query overhead if g_main_context_pending
6289 says no events are pending.
6290 (gfds, gfds_size): Remove these static vars.
6291 (xgselect_initialize): Remove; no longer needed.
6292 All uses and decls removed.
6294 * emacs.c (fatal_error_signal_hook): Remove.
6295 All uses removed. This leftover from old code was always 0.

6322 Use bool for booleans, instead of int.
6323 * lisp.h, process.h: Adjust prototypes to match above changes.
6324 * callint.c (Fcall_interactively): Don't assume the mark's
6325 offset fits in 'int'.

6338 Use bool for booleans, instead of int.
6339 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6340 since the 1-or-0 return value is always ignored anyway.
6341 (mmap_initialized_p):
6342 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6343 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6345 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6347 * bidi.c: Use bool for boolean.
6348 This is a bit more readable, and makes the text segment of bidi.o
6349 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6350 Presumably it's faster too.

6374 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6375 compile time tests instead of run time tests on systems that do
6377 (FRAME_MAC_P): Remove leftover from deleted code.
6378 * frame.c (syms_of_frame): Remove leftover from deleted code.
6380 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

6384 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6386 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6387 Otherwise, the compiler complains about (A?B:C) where B is void
6388 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6389 (fontset_add): Return void, for FONTSET_ADD.
6391 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6393 * alloc.c: Use bool for booleans.
6394 (gc_in_progress, abort_on_gc)
6395 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6396 (dont_register_blocks) [GC_MALLOC_CHECK]:
6397 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6398 (check_string_bytes, make_specified_string, memory_full)
6399 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6400 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6401 (mark_stack, valid_pointer_p, make_pure_string)
6402 (Fgarbage_collect, survives_gc_p, gc_sweep):
6403 Use bool for booleans, instead of int.
6404 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6405 Remove unused local.
6406 * alloc.c (PURE_POINTER_P):
6407 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6408 * editfns.c (Fformat):
6409 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6411 * fns.c (sweep_weak_table):
6412 * lisp.h (suppress_checking, push_message, survives_gc_p)
6413 (make_pure_string, gc_in_progress, abort_on_gc):
6414 * lread.c (readchar, read1):
6415 * print.c (Fprin1_to_string):
6416 * xdisp.c (push_message):
6417 Use bool for booleans affected directly or indirectly by
6420 Make recently-introduced setters macros.
6421 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6422 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6423 (set_fontset_default, set_fontset_fallback): Rename from their
6424 upper-case counterparts, and make them functions rather than macros.
6425 This is more consistent with the other recently-introduced setters.
6426 These don't need to be inline, since they're local.
6428 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6430 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6431 the loop (Bug#12247).
6433 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6435 * lisp.h (vcopy): Use memcpy rather than our own loop.
6436 This fixes a performance regression introduced by the recent
6437 addition of vcopy. This means 'vcopy' will need to be modified
6438 for a copying collector, but that's OK. Also, tighten the
6439 checking in the assertion.
6441 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6443 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6444 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6445 non-base glyph for the width of the base character, according to
6446 what x_draw_composite_glyph_string_foreground expects.
6447 Generate WADJUST value according to composition_gstring_width's
6448 expectations, to produce correct width of the composed character.
6449 Reverse the sign of the DU offset produced by ScriptPlace.
6451 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6453 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6455 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6457 Avoid direct writes to contents member of struct Lisp_Vector.
6458 * lisp.h (vcopy): New function to copy data into vector.
6459 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6460 * fns.c (Ffillarray): Use ASET.
6461 * keyboard.c (timer_check_2): Use AREF and ASET.
6462 (append_tool_bar_item, Frecent_keys): Use vcopy.
6463 * lread.c (read_vector): Use ASET.
6464 * msdos.c (Frecent_doskeys): Use vcopy.
6465 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6466 (Finternal_merge_in_global_face): Use ASET and vcopy.
6467 * xfont.c (xfont_list_pattern): Likewise.

6472 the position of its buffer's point.
6473 (Fset_window_point): For the selected window always go in its
6474 buffer to the specified position.
6476 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6478 Setter macros for fontsets.
6479 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6480 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6481 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6484 2012-08-20 Glenn Morris <rgm@gnu.org>
6486 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6487 Don't assume that `ln -f' works.
6489 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6491 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6492 and later about non-assignments with no effect. See discussion at
6493 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6496 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6498 Inline setter functions for Lisp_Objects slots of struct specbinding.
6499 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6502 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6504 * window.c (select_window): Always make selected window's buffer
6507 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6509 Use AREF and ASET for docstrings of category tables.
6510 * category.h (CATEGORY_DOCSTRING): Use AREF.
6511 (SET_CATEGORY_DOCSTRING): Use ASET.
6512 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6514 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6516 Inline setter functions for hash table members.
6517 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6518 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6519 (set_hash_key_and_value, set_hash_index, set_hash_next)
6520 (set_hash_hash): New functions.
6521 * charset.c, fns.c: Adjust users.
6523 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6525 Inline getter and setter functions for per-buffer values.
6526 * buffer.h (per_buffer_default, set_per_buffer_default)
6527 (per_buffer_value, set_per_buffer_value): New functions.

6529 * buffer.c, data.c: Adjust users.
6531 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6533 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6535 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6537 Rely on <config.h> + <unistd.h> to declare 'environ',
6538 as gnulib does this if the system doesn't.
6539 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6540 Remove declaration. MS-Windows declares it on stdlib.h which is
6541 included by conf_post.h.
6542 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6543 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6544 * vm-limit.c: Include <unistd.h>, for 'environ'.
6546 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6547 (start_of_data): Remove decl; mem-limits.h provides it.
6549 * xdisp.c (handle_invisible_prop): Make it a bit faster
6550 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6552 2012-08-19 Chong Yidong <cyd@gnu.org>
6554 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6557 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6559 * .gdbinit: Use call instead of set when calling a function in the
6562 * data.c (set_internal): Don't use set_blv_found.
6563 (Fkill_local_variable): Likewise.
6565 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6567 * nsfont.m (ns_ascii_average_width): Ensure the string
6568 ascii_printable is initialized with a null-terminated character
6569 array. Otherwise, it can contain undesired extra characters.
6571 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6573 port new setting code to Sun C 5.8 2005/10/13
6574 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6575 Return void, not Lisp_Object. Otherwise, the compiler
6576 complains about (A?B:C) where B is void and C is Lisp_Object
6577 when compiling CHAR_TABLE_SET, due to the recent change to
6578 the API of sub_char_table_set_contents.
6580 2012-08-18 Chong Yidong <cyd@gnu.org>
6582 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6583 for the string case (Bug#3874).

6738 The old version was confusing because it used the same name
6739 'parent' for two different things.

6753 directly-specified attributes.
6754 (merge_face_ref): Recognize :font.
6756 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

7410 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7411 * w32.c (init_environment): Change the default values of many
7412 environment variables in dflt_envvars[] to NULL, to avoid pushing
7413 them into environment when they were not already defined.
7414 Remove the code that deletes site-lisp subdirectories from the default
7415 value of EMACSLOADPATH, as it is no longer needed.
7416 (check_windows_init_file): Now external, not static.
7417 Use Vload_path as is, without adding anything, as this function is now
7418 called when Vload_path is already set up.
7420 * w32.h (check_windows_init_file): Add prototype.
7422 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7429 installation tree, as appropriate.
7431 * callproc.c (init_callproc_1): Call decode_env_path instead of
7432 doing its equivalent by hand.

7434 the code that sets Vexec_path run on MS-Windows.
7436 * lread.c (init_lread): Add comments to #ifdef's.
7438 * msdos.c (dos_set_window_size, IT_update_begin)

7450 Remove unnecessary casts involving pointers.
7451 These casts are no longer needed now that we assume C89 or later,

7465 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7466 Remove unnecessary pointer casts.
7467 * alloc.c (record_xmalloc): New function.
7468 * lisp.h (record_xmalloc): New decl.
7469 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7470 more like a function. This is because the pointer cast is not
7471 needed. All uses changed.
7472 * print.c (print_string, print_error_message): Avoid length recalc.
7474 Improve fix for macroexp crash with debugging (Bug#12118).
7475 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7476 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7477 not supposed to be invoked from the garbage collector.
7478 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7479 (gc_aset): New function, which is like ASET but can be
7480 used in the garbage collector.
7481 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7496 headers (most versions of MinGW w32api don't).
7497 (get_security_info, create_symbolic_link)
7498 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

7505 have the required privileges.
7506 (get_file_security_desc_by_name): Rename from

7509 with addition of handling of symlinks and support for 'lstat'.
7510 If possible, get file's attributes and security information by
7511 handle, not by name. Produce S_IFLNK bit for symlinks, when
7512 called from 'lstat'.
7513 (stat, lstat): New functions, call 'stat_worker'.
7514 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7515 symlinks when the underlying filesystem supports them.
7517 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7519 Fix macroexp crash on Windows with debugging (Bug#12118).
7520 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7521 checking subscripts; problem introduced with the recent
7522 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7523 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7524 since it's used in non-static inline functions now.
7526 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7527 Don't assume buffer size fits in 'int'. Remove unused local.

7544 * category.c (CATEGORY_INLINE):
7545 * character.c (CHARACTER_INLINE):
7546 * charset.c (CHARSET_INLINE):
7547 * composite.c (COMPOSITE_INLINE):
7548 * dispnew.c (DISPEXTERN_INLINE):
7549 * sysdep.c (SYSTIME_INLINE):
7550 Define to EXTERN_INLINE, so that the corresponding functions
7551 are compiled into code.
7552 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7553 (INLINE_HEADER_END): New macros.
7554 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7574 hard-coding the path separator.
7576 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7578 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7579 This how ASET and AREF are supposed to work, and makes
7580 it easier to think about future improvements. See
7581 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7582 * charset.h (set_charset_attr): New function.

8074 the fix for 12036 would have avoided some of the problems noted in
8075 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8076 would have been more obvious.

8086 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8087 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8088 not be usable in #if. This simplifies things.
8090 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8092 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8110 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8111 (xreload, hook-run, hookpost-run): Remove.
8112 * emacs.c: Include <verify.h>.
8113 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8114 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8116 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8117 (gdb_USE_LSB_TAG): New enum constants.
8118 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

9011 Prefer snprintf to strncpy.
9012 * nsterm.m (ns_term_init):
9013 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9014 * nsterm.m (ns_term_init):
9015 Avoid the need for strncpy, by using build_string or
9016 make_unibyte_string directly. Use dtoastr, not snprintf.
9017 * process.c (Fmake_network_process): Diagnose service names that
9018 are too long, rather than silently truncating them or creating

9049 Optimize pure C strings initialization.
9050 * lisp.h (make_pure_string): Fix prototype.
9051 (build_pure_c_string): New function, defined as static inline. This
9052 provides a better opportunity to optimize away calls to strlen when
9053 the function is called with compile-time constant argument.
9054 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9055 argument, adjust users accordingly. Use build_pure_c_string where
9057 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9058 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9059 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9061 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9063 Avoid calls to strlen in miscellaneous functions.
9064 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9065 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9066 * lread.c (openp): Likewise.
9068 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9070 Avoid calls to strlen in path processing functions.
9071 * fileio.c (file_name_as_directory): Add comment. Change to add
9072 srclen argument and return the length of result. Adjust users
9074 (directory_file_name): Fix comment. Change to add srclen argument,
9075 swap 1st and 2nd arguments to obey the common convention.
9076 Adjust users accordingly.
9077 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9079 2012-07-10 Glenn Morris <rgm@gnu.org>
9081 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9086 * s/gnu.h (DATA_START): Move definitions to configure.
9088 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9089 We include usg5-4-common.h, which defines them both.
9091 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9092 O_RDONLY already includes it).
9094 Stop ns builds setting the EMACSLOADPATH environment variable.
9095 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9096 Now it does not set EMACSLOADPATH, just returns the load-path string.
9097 * nsterm.h: Update accordingly.
9098 * lread.c [HAVE_NS]: Include nsterm.h.
9099 (init_lread) [HAVE_NS]: Use ns_load_path.

9102 2012-07-09 Glenn Morris <rgm@gnu.org>
9104 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9105 since the included bsd-common.h does so.
9107 Stop ns builds setting the EMACSPATH environment variable.
9108 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9109 (ns_init_paths): Do not set EMACSPATH.
9110 * nsterm.h (ns_exec_path): Add it.
9111 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9114 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9116 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9118 * process.c (wait_reading_process_output): 'waitchannels' was unset
9119 when read_kbd || !NILP (wait_for_cell); fix this.
9121 Add GCC-style 'const' attribute to functions that can use it.
9122 * character.h (char_resolve_modifier_mask):
9123 * keyboard.h (make_ctrl_char):
9124 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

9133 Add decls with ATTRIBUTE_CONST.
9135 Minor improvements to make_formatted_string.
9136 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9137 where int is good enough, as vsprintf returns an int.
9138 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9140 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9142 Use make_formatted_string to avoid double length calculation.
9143 * lisp.h (make_formatted_string): New prototype.
9144 * alloc.c (make_formatted_string): New function.
9145 * buffer.c (Fgenerate_new_buffer_name): Use it.

9167 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9169 Move marker debugging code under MARKER_DEBUG.
9170 * marker.c (MARKER_DEBUG): Move marker debugging code under
9171 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9172 for bootstrap with --enable-checking (~3x slowdown reported
9173 by Juanma Barranquero <lekktu@gmail.com>).
9174 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9176 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9178 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9179 See <http://bugs.gnu.org/11825#29>.
9181 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9183 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9184 has no font, use the frame's font. (Bug#11813)
9185 (display_line): Add commentary about displaying truncation glyphs
9187 (produce_special_glyphs): Move here from term.c.
9189 * term.c (produce_special_glyphs): Move to xdisp.c.
9191 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9194 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9196 * xdisp.c (display_line): Avoid warning about implicit declaration
9199 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9201 * lisp.h: Remove empty conditional.
9203 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9205 * lread.c (load_path_check): Now static.
9207 Fix some minor --with-ns problems found by static checking.
9208 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9209 (x_set_font) [!HAVE_X_WINDOWS]:
9210 * image.c (xpm_load_image) [HAVE_NS]:
9211 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9212 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9213 Remove unused local.
9214 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9215 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9216 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9217 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9218 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9219 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9220 Fix pointer signedness problem.

9222 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9224 2012-07-07 Glenn Morris <rgm@gnu.org>
9226 * lread.c (load_path_check): New function, split from init_lread.
9227 (init_lread): Reorganize. Motivation:
9228 If EMACSLOADPATH is set, check/warn about that rather than the
9229 defaults, which we are not going to use. Hence we can remove
9230 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9231 Don't warn if site-lisp directories are missing.
9232 If not installed, start from a blank load-path, since
9233 PATH_LOADSEARCH refers to the eventual installation directories.
9235 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9237 Support truncation and continuation glyphs on GUI frames, when
9238 fringes are disabled. (Bug#11832)
9239 * xdisp.c (init_iterator): Get dimensions of truncation and
9240 continuation glyphs even if on GUI frames.
9241 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9242 or both, are absent.
9243 (start_display, move_it_in_display_line_to): Handle the case of a
9244 GUI frame without a fringe to display continuation or truncation
9246 (insert_left_trunc_glyphs): Support GUI frames: make sure
9247 truncation glyphs overwrite enough glyphs from the current line to
9248 have sufficient space in pixels.
9249 (display_line): Support truncation and continuation glyphs on GUI
9250 frames. If some spare pixels are left on the line after inserting
9251 the truncation glyphs, fill that space with a stretch glyph of a
9252 suitably computed width.
9254 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9255 produce_glyphs, to support GUI sessions.
9257 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9259 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9261 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9263 Do not require float-time's arg to fit in time_t (Bug#11825).
9264 This works better on hosts where time_t is unsigned, and where
9265 float-time is applied to the (negative) difference between two times.
9266 * editfns.c (decode_time_components): Last arg is now double *,
9267 not int *, and means to store all the result as a double, without
9268 worrying about whether the seconds part fits in time_t.
9269 All callers changed.
9270 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9271 All callers changed.
9272 (Ffloat_time): Do not fail merely because the specified time falls
9273 outside of time_t range.
9275 2012-07-07 Glenn Morris <rgm@gnu.org>
9277 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9283 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9284 Update dependencies.
9286 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9288 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

9292 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9293 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9294 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

9297 * xfont.c (compare_font_names): Redo to omit the need for casts.
9299 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9301 * xfns.c (Fx_change_window_property): Doc fix.
9302 * w32fns.c (Fx_change_window_property): Doc fix.
9304 * w32fns.c (Fx_window_property): Accept the same arguments as the
9305 X Windows version. Doc fix.
9306 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9308 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9309 Eli Zaretskii <eliz@gnu.org>
9311 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9312 Windows-specific code from nt/config.nt moved here.
9313 Obsolete settings removed.
9315 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9317 * process.c: Avoid unnecessary calls to gettime.
9318 (wait_reading_process_output): Don't get the time of day
9319 when gobbling data immediately and not waiting, as there's no need
9320 for it in that case. This removes a FIXME.
9322 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9324 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9325 is defined (Bug#11768).
9327 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9329 Fix marker debugging code.
9330 * marker.c (byte_char_debug_check): Do not perform the check
9331 if buffer is not multibyte.
9332 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9333 Call byte_char_debug_check with correct arguments.
9335 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9337 Compile marker debugging code only if ENABLE_CHECKING is defined.
9338 * marker.c (byte_char_debug_check, count_markers):
9339 Use only if ENABLE_CHECKING is defined.
9340 (byte_debug_flag): Remove.
9341 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9342 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9344 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9346 Avoid code repetition in marker-related functions.
9347 * marker.c (attach_marker): New function.
9348 (Fset_marker, set_marker_restricted, set_marker_both)
9349 (set_marker_restricted_both): Use it.
9350 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9351 Consistently rename charno to charpos.
9352 (marker_position): Add eassert.
9353 (marker_byte_position): Convert to eassert.

9372 * window.c (save_window_save): Likewise.
9374 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9376 Do not use Fdelete_overlay in delete_all_overlays
9377 to avoid redundant calls to unchain_overlay.
9378 * buffer.c (drop_overlay): New function.
9379 (delete_all_overlays, Fdelete_overlay): Use it.
9380 * minibuf.c (get_minibuffer): Fix comment.
9382 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9384 Port to OpenBSD 5.1 amd64.
9385 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9386 This is needed for OpenBSD, and should be harmless on all BSD systems.
9387 Also, include <sys/sysctl.h>, as it should be available on all
9388 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9389 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9390 use p_pid member, not kp_proc.pid.
9392 2012-07-06 Glenn Morris <rgm@gnu.org>
9394 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9396 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9398 More xmalloc and related cleanup.

9407 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9409 Omit needless casts involving void * pointers and allocation.
9410 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9411 as the former is more robust if P's type is changed.
9412 Prefer xzalloc to xmalloc + memset 0.
9413 Simplify malloc-or-realloc to realloc.
9414 Don't worry about xmalloc returning a null pointer.
9415 Prefer xstrdup to xmalloc + strcpy.
9416 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9418 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9419 alloca of a constant.
9421 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9423 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9424 hscroll is larger than the line width. Fixes long and futile
9425 looping inside extend_face_to_end_of_line (on a TTY) producing
9426 glyphs that are not needed and thrown away.
9428 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9430 * marker.c (set_marker_restricted_both): Simplify by using

9456 * xdisp.c (window_hscroll_limited): New function.
9457 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9458 coordinates when window's hscroll is set to insanely large
9461 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9463 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9464 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

9524 * fileio.c (time_error_value): Check the right error number.
9525 Problem reported by Troels Nielsen in
9526 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9528 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9530 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9531 This should be fixed in a better way; see Eli Zaretskii in
9532 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9533 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9535 * fileio.c (time_error_value): Rename from special_mtime.
9536 The old name's problems were noted by Eli Zaretskii in
9537 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9539 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9540 This variable's comment says Emacs needs at least one GDB-visible
9541 symbol of type enum pvec_type, to work around GDB problems.
9542 The symbol's value doesn't matter.
9544 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9545 that causes compilation to fail on pre-C99 compilers.
9547 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9549 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9552 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9554 * buffer.c (init_buffer_once): Fix initialization of
9555 headers for buffer_defaults and buffer_local_symbols.
9556 Reported by Juanma Barranquero <lekktu@gmail.com>.
9558 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9560 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9561 * lisp.h (enum pvec_type): Use fewer bits.
9562 (PSEUDOVECTOR_SIZE_BITS): New constant.
9563 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9564 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9565 change in pvec_type.
9566 (PSEUDOVECTOR_TYPEP): New macro.
9567 (TYPED_PSEUDOVECTORP): Use it.
9568 * fns.c (internal_equal): Adapt code to extract pvectype.

9570 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9571 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9572 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9573 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9574 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9575 abusing vector->header.next.nbytes.
9576 (live_vector_p): Use PVEC_TYPE.
9577 (mark_object): Adapt code to extract pvectype. Use switch.
9579 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9581 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9582 Tighten new eassert a bit.
9584 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9586 Fix compilation with --enable-gcc-warnings and -O1
9588 * doprnt.c (doprnt): Change type of tem to int, initialize
9589 to avoid compiler warning. Add eassert.
9590 * search.c (simple_search): Initialize match_byte to avoid
9591 compiler warning. Add eassert.
9593 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9595 Avoid weird behavior with large horizontal scrolls.
9596 Without this change, for example, large hscroll values would
9597 mess up Emacs's display on Fedora 15 x86, presumably due to
9598 overflows in int calculations in the display code.
9599 Also, if buffers had long lines, Emacs would freeze.
9600 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9601 (set_window_hscroll): New function, containing the old guts of
9602 Fset_window_hscroll. Return the clipped value.
9603 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9604 This avoids the need to check against PTRDIFF_MAX.
9606 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9608 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9610 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9612 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9614 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9615 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9616 since GCC 4.4.6 issues a bogus warning for them.
9618 Fix bugs in file timestamp newness comparisons.
9619 * fileio.c (Ffile_newer_than_file_p):
9620 * lread.c (Fload): Use full timestamp resolution of files,
9621 not just the 1-second resolution, so that files that are only
9622 slightly newer still count as newer.
9623 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9624 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9626 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9628 * fileio.c: Improve handling of file time marker. (Bug#11852)
9629 (special_mtime): New function.
9630 (Finsert_file_contents, Fverify_visited_file_modtime):
9631 Use it to set special mtime values consistently.
9633 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9635 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9636 marker for non-existing file. (Bug#11852)
9638 2012-07-03 Glenn Morris <rgm@gnu.org>
9640 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9641 and did not make it into globals.h).
9643 2012-07-03 Tom Tromey <tromey@redhat.com>
9645 * window.c (Fset_window_margins, Fset_window_fringes)

9670 * intervals.h: Remove EXFUNs.
9671 * fontset.h: Remove EXFUN.

9679 * xterm.h: Remove EXFUN.
9681 2012-07-03 Glenn Morris <rgm@gnu.org>
9683 * lisp.h (Frandom): Make it visible to C.
9684 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9685 buffer for invisible buffers. (Bug#1229)
9687 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9689 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9690 values which aren't power of 2.
9691 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9692 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9695 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9697 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9699 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9701 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9703 * alloc.c (allocate_vector_block): Remove redundant
9704 calls to mallopt if DOUG_LEA_MALLOC is defined.
9705 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9706 avoid calls to mallopt if zero_vector is returned.
9708 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9710 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9711 is enabled, avoid dereferencing NULL current_sblock if
9714 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9716 Cleanup basic buffer management.
9717 * buffer.h (struct buffer): Change layout to use generic vector
9718 marking code. Fix some comments. Change type of 'clip_changed'
9719 to bitfield. Remove unused #ifndef old.
9720 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9721 (GET_OVERLAYS_AT): Fix indentation.
9722 (for_each_per_buffer_object_at): New macro.

9726 * alloc.c (allocate_buffer): Adjust to match new layout of
9727 struct buffer. Fix comment.
9728 (mark_overlay): New function.

9730 Lisp area of struct buffer.
9731 (mark_object): Use it. Adjust marking of misc objects
9732 and related comments.
9734 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9736 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9737 wrapper that is not needed because the wrapped code is a no-op (zero
9738 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9739 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9741 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9743 * alloc.c (mark_buffer): Simplify. Remove prototype.
9744 (mark_object): Add comment. Reorganize marking of vector-like
9745 objects. Use CHECK_LIVE for all vector-like objects except buffers
9746 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9747 Avoid redundant calls to mark_vectorlike for bool vectors.
9749 2012-06-30 Glenn Morris <rgm@gnu.org>
9751 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9753 * epaths.in (PATH_SITELOADSEARCH): New.
9754 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9755 This is rather than relying on --enable-locallisppath elements
9756 having "site-lisp" in their names. (Bug#10208#25, 11658)
9758 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9760 * w32proc.c (sys_select): Accept and ignore one more argument.
9762 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9764 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9765 (pselect) [!MS_DOS]: Redirect to sys_select.
9767 * sysdep.c: Don't include dos.h and dosfns.h.
9769 * process.c (sys_select):
9770 * msdos.c (sys_select): Accept one more argument and ignore it.
9772 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9773 adapt data types and code to that.
9776 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9777 which clashes with the gnulib function of the same name.
9779 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9781 * font.c (font_style_to_value, font_style_symbolic)
9782 (font_prop_validate_style): Add type checks for values in
9785 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9787 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9790 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9792 * xdisp.c (try_window_id): Undo last change.
9794 * w32.c (getwd): Adjust commentary about startup_dir.
9795 (init_environment): Always call sys_access, even in non-MSVC
9796 builds. Don't chdir to the directory of the Emacs executable.
9797 This undoes code from 1997 which was justified by the need to
9798 "avoid conflicts when removing and renaming directories". But its
9799 downside was that every relative file name was being interpreted
9800 relative to the directory of the Emacs executable, which can never
9801 be TRT. In particular, it broke sys_access when called with
9802 relative file names.
9803 (sys_access): Map GetLastError to errno.
9805 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9807 * window.h (struct window): Change type of 'fringes_outside_margins'

9811 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9814 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9816 * gnutls.c (emacs_gnutls_handshake):
9817 Add QUIT to make the loop interruptible.
9819 2012-06-29 Glenn Morris <rgm@gnu.org>
9821 * charset.c (init_charset): Make lack of etc/charsets fatal.
9823 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9825 * editfns.c (region_limit): Fix type mismatch.
9827 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9829 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9830 undefined. Convert from xassert to eassert.
9831 * nsmenu.m: Convert from xassert to eassert.
9832 * nsterm.m: Likewise.
9834 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9836 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9838 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9840 Avoid integer overflow on scroll-left and scroll-right.
9841 * window.c (HSCROLL_MAX): New macro.
9842 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9843 overflow when requested scroll falls outside ptrdiff_t range.
9845 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9847 * window.h (struct window): Change type of 'hscroll',
9848 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9849 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9850 Adjust users accordingly.
9851 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9852 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9853 from EMACS_INT to ptrdiff_t.
9854 (make_window): Omit redundant initialization.
9856 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9860 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9862 * window.h (struct window): Change type of 'use_time' and
9863 'sequence_number' from Lisp_Object to int.

9873 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9874 adjust comments accordingly.

9929 * alloc.c (allocate_string): Omit intervals initialization.
9930 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9931 as in make_pure_string and make_pure_c_string.
9933 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9987 * alloc.c: Remove build_string.
9988 * lisp.h: Define build_string as static inline. This provides
9989 a better opportunity to optimize away calls to strlen when the
9990 function is called with compile-time constant argument.
9991 * image.c (imagemagick_error): Convert to build_string.
9992 * w32proc.c (sys_spawnve): Likewise.
9993 * xterm.c (x_term_init): Likewise.
9995 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9997 Use sprintf return value instead of invoking strlen on result.
9998 In the old days this wasn't portable, since some sprintf
9999 implementations returned char *. But they died out years ago and
10000 Emacs already assumes sprintf returns int.
10001 Similarly for float_to_string.
10002 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10003 * ccl.c (ccl_driver):
10004 * character.c (string_escape_byte8):

10007 * print.c (print_object):
10008 * xdisp.c (message_dolog):
10009 * xfns.c (syms_of_xfns):
10010 Use sprintf or float_to_string result to avoid need to call strlen.
10011 * data.c (Fnumber_to_string):
10012 Use make_unibyte_string, since the string must be ASCII.
10013 * lisp.h, print.c (float_to_string): Now returns int length.
10014 * term.c (produce_glyphless_glyph):
10015 Use sprintf result rather than recomputing it.
10017 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10018 * Makefile.in (ALL_CFLAGS):
10019 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
10020 * gmalloc.c, regex.c: Include <config.h> unconditionally.
10022 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10024 * dispextern.h (xstrcasecmp): Define to library function
10025 strcasecmp if available.
10026 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
10028 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
10030 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

10032 * menu.c (push_submenu_start, push_submenu_end)
10033 (push_left_right_boundary, push_menu_pane): Likewise.
10034 * msdos.c (dos_rawgetc): Likewise.

10041 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
10043 * gtkutil.c (get_utf8_string): Remove redundant assignment.
10044 sprintf already null-terminates its output.
10046 * xfns.c (x_window): Remove redundant cast.
10048 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10050 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10051 `const char *' to `char *' to avoid compiler warning.
10053 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10055 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10056 instead of truncating it to 63 (admittedly a generous limit).
10058 * process.c: Fix spelling and caps in comments.
10060 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10062 * emacs.c (setpgrp): Remove definition, unused.

10072 (SYSTIME_H): Add nt/inc/sys/time.h.
10074 * systime.h [WINDOWSNT]: Include sys/time.h.
10076 * s/ms-w32.h (struct timespec): Definition moved from
10077 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10079 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10109 Remove unnecessary forward decls.
10111 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10113 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10114 * lisp.h (WAIT_READING_MAX): New macro.
10115 * dispnew.c (Fsleep_for, sit_for):
10116 * keyboard.c (kbd_buffer_get_event):
10117 * process.c (Faccept_process_output):
10118 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10119 This improves on the previous patch, which introduced a bug
10120 when time_t is unsigned and as wide as intmax_t.
10121 See <http://bugs.gnu.org/9000#51>.
10123 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10125 * dispnew.c (sit_for, Fsleep_for):
10126 * keyboard.c (kbd_buffer_get_event):

10130 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
10132 * makefile.w32-in: Update dependencies.

10139 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
10140 Privately reported by Herbert J. Skuhra.
10141 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10143 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
10144 not make_lisp_timeval, when the argument is of type EMACS_TIME.
10146 2012-06-23 Eli Zaretskii <eliz@gnu.org>
10148 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
10149 last argument of make_unibyte_string.
10151 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10152 language ID in the event parameters.
10154 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10155 event.code, not the obscure "character set ID".
10157 2012-06-23 Chong Yidong <cyd@gnu.org>
10159 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10182 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10183 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10184 Don't assume EMACS_TIME and struct timeval are the same type.
10186 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10188 Support higher-resolution time stamps (Bug#9000).
10189 The time stamps are only nanosecond-resolution at the C level,
10190 since that's the best that any real-world system supports now.
10191 But they are picosecond-resolution at the Lisp level, as that's
10192 easy, and leaves room for future OS improvements.
10194 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10197 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10198 Don't get current time unless it's needed.
10200 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10201 now provides it if it's absent.
10202 (start_atimer): Port to higher-res time stamps.
10203 Check for time stamp overflow. Don't get current time more
10204 often than is needed.
10206 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10207 Include systime.h, not time.h.
10208 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10210 * dired.c: Include stat-time.h.
10211 (Ffile-attributes): File times now have higher resolution.
10213 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10214 (struct image): Timestamp now has higher resolution.
10216 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10217 has at least microseconds now. All uses removed.
10218 (update_frame, update_single_window, update_window, update_frame_1)
10219 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10220 (duration_to_sec_usec): Remove; no longer needed.
10222 * editfns.c (time_overflow): Now extern.
10223 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10224 (float-time, Fformat_time_string, Fcurrent_time_string)
10225 (Fcurrent_time_zone): Accept and generate higher-resolution
10227 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10228 (decode_time_components, lisp_seconds_argument): New functions.
10229 (make_time): Now static.
10230 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10231 Report an error if the time is invalid, rather than having the caller
10234 * fileio.c: Include <stat-time.h>
10235 (Fcopy_file): Copy higher-resolution time stamps.
10236 Prefer to set the time stamp via a file descriptor if that works.
10237 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10238 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10239 (Fvisited_file_modtime, Fset_visited_file_modtime):
10240 Support higher-resolution time stamps.
10242 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10244 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10246 * image.c (prepare_image_for_display, clear_image_cache)
10247 (lookup_image): Port to higer-resolution time stamps.
10249 * keyboard.c (start_polling, bind_polling_period):
10250 Check for time stamp overflow.
10251 (read_char, kbd_buffer_get_event, timer_start_idle)
10252 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10253 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10254 Port to higher-resolution time stamps. Do not assume time_t is signed.
10255 (decode_timer): New function. Timers are now vectors of length 9,
10256 not 8, to accommodate the picosecond component.
10257 (timer_check_2): Use it.
10259 * nsterm.m (select_timeout, timeval_subtract): Remove.
10260 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10261 as they're a bit more accurate and handle overflow better.
10262 (ns_select): Change prototype to be compatible with pselect.
10263 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10264 * nsterm.h (ns_select): Adjust prototype.
10266 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10267 us-resolution time stamps.
10268 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10270 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10272 * lisp.h (time_overflow): New decl.
10273 (wait_reading_process_output): First arg is now intmax_t, not int,
10274 to accommodate larger waits.
10276 * process.h (struct Lisp_Process.read_output_delay):
10277 Now counts nanoseconds, not microseconds.
10278 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10280 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10281 (wait_reading_process_output):
10282 Port to ns-resolution time stamps.
10283 (Faccept_process_output, wait_reading_process_output):
10284 Check for time stamp overflow. Do not assume time_t is signed.
10285 (select_wrapper): Remove; we now use pselect.
10286 (Fprocess_attributes): Now generates ns-resolution time stamps.
10288 * sysdep.c: Include utimens.h. Don't include utime.h
10289 or worry about struct utimbuf; gnulib does that for us now.
10290 (gettimeofday): Remove; gnulib provides a substitute.
10291 (make_timeval): New function.
10292 (set_file_times): Now sets ns-resolution time stamps.
10293 New arg FD; all uses changed.
10294 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10295 (system_process_attributes):
10296 Now returns ns-resolution time stamp. All uses changed.
10297 Check for time stamp overflow.
10299 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10300 provides a substitute now.
10302 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10303 since it guarantees struct timespec.
10304 (EMACS_TIME): Now struct timespec, so that we can support
10305 ns-resolution time stamps.
10306 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10307 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10308 (EMACS_USECS): Remove.
10309 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10310 so multiply the arg by 1000 before storing it.
10311 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10313 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10314 Port to ns-resolution time stamps.
10315 (EMACS_TIME_NEG_P): Remove; replaced by....
10316 (EMACS_TIME_SIGN): New macro.
10317 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10318 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10319 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10320 (make_timeval, make_lisp_time, decode_time_components): New decls.
10321 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10322 that it mishandled time_t overflow. You can't compare by subtracting!
10323 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10324 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10326 * term.c: Include <sys/time.h>.
10327 (timeval_to_Time): New function, for proper overflow wraparound.
10328 (term_mouse_position, term_mouse_click): Use it.
10330 * undo.c (record_first_change): Support higher-resolution time stamps
10331 in the undo buffer.
10332 (Fprimitive_undo): Use them when restoring time stamps.
10334 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10335 (w32_get_internal_run_time):
10336 Port to higher-resolution Emacs time stamps.
10337 (ltime): Now accepts single 64-bit integer, as that's more convenient
10340 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10342 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10343 for compatibility with pselect. Support ns-resolution time stamps.
10345 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10347 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10348 Check for time stamp overflow, and support ns-resolution time stamps.
10350 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10351 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10352 (timeval_subtract): Remove; no longer needed.
10353 (XTflash, XTring_bell, x_wait_for_event):
10354 Port to ns-resolution time stamps. Don't assume time_t is signed.
10356 2012-06-22 Chong Yidong <cyd@gnu.org>
10358 * xdisp.c (x_consider_frame_title): Revert last change.
10360 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10362 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10363 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10364 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10365 staticidx goes up to 1597 out of 1600 = 0x640.)
10367 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10369 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10370 Otherwise, the umask might be mistakenly 0 while handling input signals.
10372 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10374 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10380 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10381 access to `contents' member of Lisp_Vector objects with AREF and ASET
10384 2012-06-19 Chong Yidong <cyd@gnu.org>
10386 * frame.c (delete_frame): When selecting a frame on a different
10387 text terminal, do not alter the terminal's top-frame.
10389 * xdisp.c (format_mode_line_unwind_data): Record the target
10390 frame's selected window and its terminal's top-frame.
10391 (unwind_format_mode_line): Restore them.
10392 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10394 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10395 since tty frames can be explicitly named.
10396 (prepare_menu_bars): Likewise.
10398 * term.c (Ftty_top_frame): New function.
10400 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10402 Port byte-code-meter to modern targets.
10403 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10404 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10405 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10406 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10407 (METER_1, METER_2): Simplify.
10409 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10411 * data.c (Fdefalias): Return `symbol' (bug#11686).
10413 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10415 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10416 gets killed during executing of this function (Bug#11665).
10417 Try to always return Qt when the buffer has been actually killed.
10418 (Vkill_buffer_query_functions): In doc-string say that functions
10419 run by this hook should not change the current buffer.

10640 Use an inline function on all platforms when using the union type,
10641 since this is simpler and 'static inline' can be used portably

10786 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10787 would mishandle a string argument "Xc" if X was a multibyte

10842 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10843 Convert pctcpu and pctmem to Lisp float properly.
10844 Let the compiler fold better, as 100.0/0x8000 is exact.

10848 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10871 Use 'float' consistently, rather than 'float' in most places
10872 and 'double' in a couple of places.
10874 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10876 * xdisp.c (handle_stop): Detect whether we have overlay strings
10877 loaded by testing it->current.overlay_string_index to be
10878 non-negative, instead of checking whether n_overlay_strings is
10879 positive. (Bug#11587)
10881 2012-05-31 Chong Yidong <cyd@gnu.org>
10883 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10885 * doc.c (Fsubstitute_command_keys): Doc fix.
10887 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10889 * search.c (search_buffer): Remove calls to
10890 r_alloc_inhibit_buffer_relocation, as it is now called by
10891 maybe_unify_char, which was the cause of relocation of buffer text
10894 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10896 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10897 for the duration of call to load_charset, to avoid problems with
10898 callers of maybe_unify_char that access buffer text through C
10901 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10902 decrement the inhibition flag, instead of just setting or
10905 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10907 Remove obsolete '#define static' cruft.
10908 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10909 This #undef was "temporary" in 2000; it is no longer needed
10910 now that '#define static' has gone away.
10911 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10912 (gray_bitmap_bits): Remove; no longer needed.
10913 All uses replaced with definiens.
10914 * xterm.c: Include "bitmaps/gray.xbm".
10916 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10918 Clean up __executable_start, monstartup when --enable-profiling.
10919 The following changes affect the code only when profiling.
10920 * dispnew.c (__executable_start): Rename from safe_bcopy.
10921 Define only on platforms that need it.
10922 * emacs.c: Include <sys/gmon.h> when profiling.
10923 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10924 (__executable_start): Remove decl, since lisp.h does it now.
10925 (safe_bcopy): Remove decl; no longer has that name.
10926 (main): Coalesce #if into single bit of code, for simplicity.
10927 Cast pointers to uintptr_t, since standard libraries want integers
10929 * lisp.h (__executable_start): New decl.
10931 2012-05-31 Glenn Morris <rgm@gnu.org>
10933 * image.c (Fimagemagick_types): Doc fix.
10935 2012-05-30 Jim Meyering <meyering@redhat.com>
10937 * callproc.c (Fcall_process_region): Include directory component
10938 in mkstemp error message (Bug#11586).
10940 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10942 * alloc.c, lisp.h (make_pure_vector): Now static.
10944 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10946 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10947 Move to byte-run.el.
10948 (Fautoload): Do the hash-doc more carefully.
10949 * data.c (Fdefalias): Purify definition, except for keymaps.
10950 (Qdefun): Move from eval.c.
10951 * lisp.h (Qdefun): Remove.
10952 * lread.c (read1): Tiny simplification.
10954 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10956 Do not create empty overlays with the evaporate property (Bug#9642).
10957 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10958 Bug#9642, but explicitly check that the buffer the overlay would
10959 be moved to is live and rearrange lines to make sure that errors
10960 will not put the overlay in an inconsistent state.
10961 (Fdelete_overlay): Cosmetics.
10963 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10965 * w32term.c (my_bring_window_to_top): New function.
10966 (x_raise_frame): Use handle returned by DeferWindowPos, which
10967 could be different from the original one.
10968 Call my_bring_window_to_top instead of my_set_foreground_window.
10971 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10972 by calling BringWindowToTop.
10974 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

10977 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10979 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10980 This avoids undefined behavior that might cause the eassert
10981 to not catch an out-of-range value.
10983 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10985 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10986 Update dependencies.
10988 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10990 * bidi.c (bidi_mirror_char): Fix last change.
10992 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10994 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10995 when referring to sectname field in printf format.
10997 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10999 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11000 Only r_alloc_inhibit_buffer_relocation needed to be added;
11001 the others were already declared.
11003 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11004 before checking whether it's out of range. Put the check inside
11006 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11008 2012-05-27 Ken Brown <kbrown@cornell.edu>
11010 * callproc.c (Fcall_process): Restore a line that was accidentally
11011 commented out in the 2011-02-13 change (bug#11547).
11013 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11015 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11016 defined on ralloc.c.
11018 * buffer.c [REL_ALLOC]: Remove prototypes of
11019 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11020 they are now on lisp.h.
11022 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11024 * search.c (search_buffer): Use it to inhibit relocation of buffer
11025 text while re_search_2 is doing its job, because re_search_2 is
11026 passed C pointers to buffer text. (Bug#11519)
11028 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11029 Update value to 24.
11031 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11032 state after an additional call to move_it_in_display_line_to, keep
11033 the values of it->max_ascent and it->max_descent found for the
11035 (pos_visible_p): Revert the comparison against bottom_y to what it
11036 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11039 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11041 Fix coding-related core dumps with gcc -ftrapv.
11042 The code was computing A - B, where A and B are pointers, and B is
11043 random garbage. This can lead to core dumps on platforms that
11044 have special pointer registers, and it also leads to core dumps on
11045 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11046 A - B only when B is initialized properly.
11047 * coding.c (coding_set_source, coding_set_destination): Return void.
11048 (coding_change_source, coding_change_destinations): New functions,
11049 with the old behaviors of coding_set_source and coding_set_destination.
11050 All callers that need an offset changed to use these new functions.
11052 2012-05-26 Glenn Morris <rgm@gnu.org>
11054 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11056 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11058 Extend mouse support on W32 text-mode console.
11059 * xdisp.c (draw_row_with_mouse_face):
11060 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11062 * w32console.c: Include window.h.
11063 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11065 (initialize_w32_display): Initialize mouse-highlight data.
11067 * w32inevt.c: Include termchar.h and window.h.
11068 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11069 moves, call note_mouse_highlight. If help_echo changed, call
11070 gen_help_event to produce help-echo message in the echo area.
11071 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11074 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11076 * lread.c (read1): Simplify slightly to avoid an overflow warning
11077 with GCC 4.7.0 on x86-64.
11079 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11081 * bidi.c (bidi_mirror_char): Revert last change: an int is
11082 definitely wide enough here.
11084 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11086 Fix integer width and related bugs (Bug#9874).
11087 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
11088 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
11089 (string_bytes, check_sblock, allocate_string_data):
11090 (compact_small_strings, Fmake_bool_vector, make_string)
11091 (make_unibyte_string, make_multibyte_string)
11092 (make_string_from_bytes, make_specified_string)
11093 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11094 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11096 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11097 (allocate_pseudovector):
11098 Use int, not EMACS_INT, where int is wide enough.
11099 (inhibit_garbage_collection, Fgarbage_collect):
11100 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11101 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11102 int might not be wide enough.
11103 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11104 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11105 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11106 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11107 (bidi_level_of_next_char, bidi_move_to_visually_next):
11108 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11109 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11110 (Fkill_buffer, Fset_buffer_major_mode)
11111 (advance_to_char_boundary, Fbuffer_swap_text)
11112 (Fset_buffer_multibyte, overlays_at, overlays_in)
11113 (overlay_touches_p, struct sortvec, record_overlay_string)
11114 (overlay_strings, recenter_overlay_lists)
11115 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11116 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
11117 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
11118 (Foverlay_recenter, last_overlay_modification_hooks_used)
11119 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11120 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11121 (validate_region): Omit unnecessary test for b <= e,
11122 since that's guaranteed by the previous test.
11123 (adjust_overlays_for_delete): Avoid pos + length overflow.
11124 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11125 (report_overlay_modification):
11126 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11127 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11128 Omit pointer cast, which isn't needed anyway, and doesn't work
11129 after the EMACS_INT -> ptrdiff_t change.
11130 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11131 * buffer.h: Adjust decls to match defn changes elsewhere.
11132 (struct buffer_text, struct buffer):
11133 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11134 Use EMACS_INT, not int, where int might not be wide enough.
11135 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11136 not int, to avoid needless 32-bit limit on 64-bit hosts.
11137 (exec_byte_code): Use tighter memory-full test, one that checks
11138 for alloca overflow. Don't compute the address of the object just
11139 before an array, as that's not portable. Use EMACS_INT, not
11140 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11141 * callint.c (Fcall_interactively):
11142 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11143 * callproc.c (call_process_kill, Fcall_process):
11144 Don't assume pid_t fits into an Emacs fixnum.
11145 (call_process_cleanup, Fcall_process, child_setup):
11146 Don't assume pid_t fits into int.
11147 (call_process_cleanup, Fcall_process, delete_temp_file)
11148 (Fcall_process_region):
11149 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11150 (Fcall_process): Simplify handling of volatile integers.
11151 Use int, not EMACS_INT, where int will do.
11152 * casefiddle.c (casify_object, casify_region, operate_on_word)
11153 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11154 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11155 (casify_object): Avoid integer overflow when overallocating buffer.
11156 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11157 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11158 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11159 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11160 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11161 integers are now checked earlier. All uses replaced with XINT.
11163 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11164 For CCL_MapSingle, check that content and value are in int range.
11165 (ccl_driver, Fregister_code_conversion_map):
11166 Check that Vcode_version_map_vector is a vector.
11167 (resolve_symbol_ccl_program): Check that vector header is in range.
11168 Always copy the vector, so that we can check its contents reliably
11169 now rather than having to recheck each instruction as it's being
11170 executed. Check that vector words fit in 'int'.
11171 (ccl_get_compiled_code, Fregister_ccl_program)
11172 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11173 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11174 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11175 contents are in range.
11176 (Fccl_execute_on_string): Check that status is in range.
11177 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11178 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11179 Accept and return EMACS_INT, not int, because callers can pass values
11180 out of 'int' range.
11181 (c_string_width, strwidth, lisp_string_width, chars_in_text)
11182 (multibyte_chars_in_text, parse_str_as_multibyte)

11184 (str_as_unibyte, str_to_unibyte, string_count_byte8)
11185 (string_escape_byte8, Fget_byte):
11186 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11187 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11188 avoid mishandling large integers.
11189 * character.h: Adjust decls to match defn changes elsewhere.
11190 * charset.c (load_charset_map_from_file, find_charsets_in_text)
11191 (Ffind_charset_region):
11192 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11193 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
11194 (load_charset_map_from_vector, Fdefine_charset_internal):
11195 Don't assume fixnum fits in int.
11196 (load_charset_map_from_vector, Fmap_charset_chars):
11197 Remove now-unnecessary CHECK_NATNUMs.
11198 (Fdefine_charset_internal): Check ranges here, more carefully.
11199 Don't rely on undefined behavior with signed left shift overflow.
11200 Don't assume unsigned int fits into fixnum, or that fixnum fits
11201 into unsigned int. Don't require max_code to be a valid fixnum;
11202 that's not true for gb10830 4-byte on a 32-bit host. Allow
11203 invalid_code to be a cons, for the same reason. Require code_offset
11204 to be a character. Avoid int overflow if max_char is close
11206 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11207 this is intended anyway and avoids some undefined behavior.
11208 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11209 INDEX_TO_CODE_POINT, as that's what it expects.
11210 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11211 * charset.h (DECODE_CHAR): Return int, not unsigned;
11212 this is what was intended anyway, and it avoids undefined behavior.
11213 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11214 integer-overflow issues.
11215 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11216 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11217 where the argument is EMACS_INT, and this behavior is not intended.
11218 * chartab.c (Fmake_char_table, Fset_char_table_range)
11219 (uniprop_get_decoder, uniprop_get_encoder):
11220 Don't assume fixnum fits in int.
11221 * cmds.c (move_point): New function, that does the gist of
11222 Fforward_char and Fbackward_char, but does so while checking
11223 for integer overflow more accurately.
11224 (Fforward_char, Fbackward_char): Use it.
11225 (Fforward_line, Fend_of_line, internal_self_insert)
11226 (internal_self_insert):
11227 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11228 Fix a FIXME, by checking for integer overflow when calculating
11229 target_clm and actual_clm.

11261 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11262 (consume_chars): Rewrite to not calculate an address outside buffer.
11263 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
11264 Don't access memory outside of the args array.
11265 (Fdefine_coding_system_internal): Check for charset-id overflow.
11266 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
11267 result of ENCODE_CHAR.

11949 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
11950 * textprop.c, tparam.c (NULL): Remove.
11951 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
11952 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11953 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11954 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11955 * xterm.c (input_signal_count): Assume volatile works.
11957 2012-05-21 Ken Brown <kbrown@cornell.edu>
11959 * xgselect.c (xg_select): Fix first argument in call to 'select'
11962 2012-05-20 Ken Brown <kbrown@cornell.edu>
11964 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11965 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11967 2012-05-19 Ken Brown <kbrown@cornell.edu>
11969 * xfns.c (x_in_use): Remove `static' qualifier.
11970 * xterm.h (x_in_use): Declare.
11971 * xgselect.c: Include xterm.h.
11972 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11973 and `display_arg' (bug#9754).
11975 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11977 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11979 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11980 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11982 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11984 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11986 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11987 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11989 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11990 reference to image_cache->refcount.
11991 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11993 2012-05-17 Juri Linkov <juri@jurta.org>
11995 * search.c (Fword_search_regexp, Fword_search_backward)
11996 (Fword_search_forward, Fword_search_backward_lax)
11997 (Fword_search_forward_lax): Move functions to isearch.el
11998 (bug#10145, bug#11381).
12000 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12002 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12004 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12006 * lread.c (init_obarray): Declare Qt and Qnil as special.
12008 2012-05-14 Glenn Morris <rgm@gnu.org>
12010 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12011 Put "libexec" before "bin", for the sake of init_callproc_1.
12013 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12015 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12017 * unexaix.c: Port to more-recent AIX compilers.
12018 (report_error, report_error_1, make_hdr, copy_sym)
12019 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12020 Make arguments const char *, not char *, to avoid violations of C
12021 standard and to fix some AIX warnings reported by Gilles Pion.
12023 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12025 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12026 already have overlays loaded.
12027 (handle_single_display_spec): Before returning without displaying
12028 fringe bitmap, synchronize the bidi iterator with the main display
12029 iterator, by calling iterate_out_of_display_property.
12030 (iterate_out_of_display_property): Detect buffer iteration by
12031 testing that it->string is a Lisp string.
12032 (get_next_display_element): When the current object is exhausted,
12033 and there's something on it->stack, call set_iterator_to_next to
12034 proceed with what's on the stack, instead of returning zero.
12035 (set_iterator_to_next): If called at the end of a Lisp string,
12036 proceed to consider_string_end without incrementing string
12037 position. Don't increment display vector index past the end of
12038 the display vector. (Bug#11417)
12039 (pos_visible_p): Don't report a position visible when move_it_to
12040 stopped at the last line of window, which happens to be scanned
12041 backwards by the bidi iteration. (Bug#11464)
12043 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12045 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12046 and right-margin display specs even if the spec is invalid or we
12047 are on a TTY, and thus unable to display on the fringes.
12048 That's because the text with the property will not be displayed anyway,
12049 so we need to signal to the caller that this is a "replacing"
12050 display spec. This fixes display when the spec is invalid or we
12053 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12055 * unexaix.c (make_hdr): Fix typo in prototype.
12056 This bug broke the build on AIX. Problem reported by Gilles Pion.
12058 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12060 * keyboard.c (kbd_buffer_get_event): Read special events also in
12061 batch mode. (Bug#11415)
12063 2012-05-12 Glenn Morris <rgm@gnu.org>
12065 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12067 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12069 * lisp.mk (lisp): Add newcomment.elc.
12071 2012-05-12 Glenn Morris <rgm@gnu.org>
12073 * Makefile.in (MKDIR_P): New, set by configure.
12074 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12076 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12078 Remove unused function hourglass_started.
12079 * dispextern.h (hourglass_started):
12080 * w32fns.c (hourglass_started):
12081 * xdisp.c (hourglass_started): Remove.
12083 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12085 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12086 Update dependencies.
12088 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12090 * xgselect.c (xg_select): Put maxfds+1 into a var.
12091 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12093 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12095 2012-05-10 Dave Abrahams <dave@boostpro.com>
12097 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12098 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12100 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12102 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12103 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12104 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12105 Initialize xd_registered_buses.
12107 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12109 Untag more efficiently if USE_LSB_TAG.
12110 This is based on a proposal by YAMAMOTO Mitsuharu in
12111 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12112 For an admittedly artificial (nth 8000 longlist) benchmark on
12113 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12114 Emacs's overall text size by 1%.
12115 * lisp.h (XUNTAG): New macro.
12116 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12117 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12118 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12119 * eval.c (Fautoload):
12120 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12121 * frame.h (XFRAME): Use XUNTAG.
12123 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12124 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12125 Remove unportable assumptions about print widths of types like
12127 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12128 intptr_t when converting between pointer and integer, to avoid GCC
12129 warnings about wrong width.
12131 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12133 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12134 stack for each reader_thread, instead of defaulting to 8MB
12135 determined by the linker. This avoids failures in creating
12136 subprocesses on Windows 7, see the discussion in this thread:
12137 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12139 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12141 Fix up display of the *Minibuf-0* buffer in the mini window.
12142 * keyboard.c (read_char): Don't clear the echo area if there's no
12144 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12145 contents of *Minibuf-0*) if there's no message displayed in its stead.
12147 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12149 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12152 2012-05-06 Chong Yidong <cyd@gnu.org>
12154 * lisp.mk (lisp): Update.
12156 2012-05-05 Jim Meyering <meyering@redhat.com>
12158 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12160 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12162 * data.c (PUT_ERROR): New macro.
12163 (syms_of_data): Use it. Add new error type `user-error'.
12164 * undo.c (user_error): New function.
12165 (Fprimitive_undo): Use it.
12166 * print.c (print_error_message): Adjust print style for `user-error'.
12167 * keyboard.c (user_error): New function.
12168 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12170 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12172 Do not limit current-time-string to years 1000..9999.
12173 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12174 (Fcurrent_time_string): Support any year that is supported by the
12175 underlying localtime representation. Don't use asctime, as it
12176 has undefined behavior for years outside the range -999..9999.
12178 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12180 Fix race conditions involving setenv, gmtime, localtime, asctime.
12181 Without this fix, interrupts could mess up code that uses these
12182 nonreentrant functions, since setting TZ invalidates existing
12183 tm_zone or tzname values, and since most of these functions return
12184 pointers to static storage.
12185 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12186 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12187 Grow the critical sections to include not just invoking
12188 localtime/gmtime, but also accessing these functions' results
12189 including their tm_zone values if any, and any related TZ setting.
12190 (format_time_string): Last arg is now struct tm *, not struct tm **,
12191 so that the struct tm is saved in the critical section.
12192 All callers changed. Simplify allocation of initial buffer, partly
12193 motivated by the fact that memory allocation needs to be outside
12194 the critical section.
12196 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12198 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12199 with RESET_INTERVAL.
12201 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12202 Remove duplicated buffer name initialization.
12204 2012-05-02 Jim Meyering <jim@meyering.net>
12206 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12208 * xfns.c (x_window): Use xstrdup (Bug#11375).
12210 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12212 * xdisp.c (pos_visible_p): If already at a newline from the
12213 display string before the 'while' loop, don't walk back the glyphs
12214 from it3.glyph_row. Solves assertion violation when the display
12215 string begins with a newline (egg.el). (Bug#11367)
12217 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12219 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12222 2012-05-01 Glenn Morris <rgm@gnu.org>
12224 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12225 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12226 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12227 All were removed before 23.1.
12229 * dispnew.c: Remove HAVE_LIBNCURSES test;
12230 it is always true on relevant platforms.
12232 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12233 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12235 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12237 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12239 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12240 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12243 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12245 Do not avoid creating empty evaporating overlays (Bug#9642).
12246 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12247 That is, do not delete an evaporating overlay if it becomes
12248 empty after its bounds are adjusted to fit within its buffer.
12249 This fix caused other problems, and I'm reverting it until we get
12250 to the bottom of them.
12252 2012-04-27 Chong Yidong <cyd@gnu.org>
12254 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12256 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12258 * xdisp.c (pos_visible_p): If the window start position is beyond
12259 ZV, start the display from buffer beginning. Prevents assertion
12260 violation in init_iterator when the minibuffer window is scrolled
12261 via the scroll bar.
12263 * window.c (window_scroll_pixel_based): Likewise.
12265 2012-04-27 Chong Yidong <cyd@gnu.org>
12267 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12269 2012-04-27 Glenn Morris <rgm@gnu.org>
12271 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12272 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12274 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12276 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12277 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12279 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12281 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12282 display element, check also the underlying string or buffer
12283 character. (Bug#11341)
12285 * w32menu.c: Include w32heap.h.
12286 (add_menu_item): If the call to AppendMenuW (via
12287 unicode_append_menu) fails, disable Unicode menus only if we are
12288 running on Windows 9X/Me.
12290 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12292 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12293 (xgetint): Add missing shift for LSB tags.
12295 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12297 * keyboard.c (read_char): Don't wipe echo area for select window
12298 events: These might get delayed via `mouse-autoselect-window'
12301 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12303 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12304 manipulation of :loaded-from data.
12306 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12308 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12309 now a cons (bug#11311).
12311 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12313 Do not create empty overlays with the evaporate property (Bug#9642).
12314 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12315 if it becomes empty after its bounds are adjusted to fit within
12316 its buffer. Without this fix, in a nonempty buffer (let ((o
12317 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12318 yields an empty overlay that has the evaporate property, which is
12319 not supposed to happen.
12321 Fix minor GTK3 problems found by static checking.
12322 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12323 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12324 (struct _EmacsFixedClass, emacs_fixed_get_type):
12325 Move decls here from emacsgtkfixed.h, since they needn't be public.
12326 (emacs_fixed_get_type): Now static.
12327 (emacs_fixed_class_init): Omit unused local.
12328 (emacs_fixed_child_type): Remove; unused.
12329 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
12330 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
12331 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
12332 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
12333 (EMACS_FIXED_GET_CLASS): Remove; unused.
12334 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
12336 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
12337 Problem reported by Juanma Barranquero for Windows -Wunused-function.
12339 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12341 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12342 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12343 (__malloc_size_t, __malloc_ptrdiff_t):
12344 Remove. All uses removed, replaced by the definiens if needed,
12345 since we can assume C89 or better now.
12346 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12354 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12355 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12356 Define using prototypes, not old style.
12357 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
12358 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
12359 (align): Don't assume that signed integer overflow wraps around.
12360 Omit unused local var.
12361 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
12362 (_free_internal_nolock, memalign, mallochook, reallochook):
12363 Omit no-longer-needed casts.
12364 (valloc): Use getpagesize, not __getpagesize.
12365 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
12366 (struct hdr): The 'magic' member is now size_t, not unsigned long.
12368 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
12370 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
12372 Move functions from C to Lisp. Make non-blocking method calls
12373 the default. Implement further D-Bus standard interfaces.
12375 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

12434 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12436 * sysdep.c [__FreeBSD__]: Minor cleanups.
12437 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12438 Use Emacs indenting style more consistently. Avoid some casts.

12523 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12524 (NEED_MEM_INSERT): New macro.
12525 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12526 Remove one incorrect comment and fix another.

12593 2012-04-11 Daniel Colascione <dancol@dancol.org>
12595 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12596 against is gone. It's better to use vfork now so that when Cygwin
12597 gains a new, working vfork, we use it automatically (bug#10398).
12599 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

12654 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12656 * xdisp.c (set_cursor_from_row): If the display string appears in
12657 the buffer at position that is closer to point than the position
12658 after the display string, display the cursor on the first glyph of
12659 the display string. Fixes cursor display when a 'display' text
12660 property immediately follows invisible text. (Bug#11094)
12662 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12664 composite.c: use 'double' consistently
12665 * composite.c (get_composition_id): Use 'double' consistently
12666 instead of converting 'float' to 'double' and vice versa; this is
12667 easier to understand and avoids a GCC warning.
12669 2012-04-09 Glenn Morris <rgm@gnu.org>

12735 * indent.c (Fvertical_motion): If there is a display string at
12736 point, use it.vpos to compute how many lines to backtrack after
12737 move_it_to point. (Bug#11133)
12739 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12741 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12742 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12743 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12744 macros related to unification of CJK characters. For the details,
12745 see the discussion following the message here:
12746 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

12762 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12764 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12765 position we get to after a call to move_it_to fails the
12766 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12767 only if we wind up in a string from display property. (Bug#11063)
12769 * window.c (Fdelete_other_windows_internal): Invalidate the row
12770 and column information about mouse highlight, so that redisplay
12771 restores it after reallocating the glyph matrices. (Bug#7464)
12773 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12774 string comes from a `display' text property, use the buffer
12775 position of that property as if we actually saw that position in
12777 (move_it_by_lines): Remove the assertion that
12778 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12779 violated when there's a before-string at the beginning of a line.

12837 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12839 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12840 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12841 when fetching a multibyte character consumes more bytes than
12842 CHAR_BYTES returns, due to unification of CJK characters in
12843 string_char. (Bug#11073)
12845 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12847 * process.c (wait_reading_process_output): Handle pty disconnect
12848 by refraining from sending oneself a SIGCHLD (bug#10933).

12854 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12855 Mark string as coming from a prefix property.
12856 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12857 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12859 2012-03-21 Chong Yidong <cyd@gnu.org>
12861 * xfaces.c (Vface_remapping_alist): Doc fix.
12863 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12865 * w32proc.c (Fw32_set_console_codepage)
12866 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12869 2012-03-20 Chong Yidong <cyd@gnu.org>
12871 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12872 to reflect default non-nil value of redisplay-dont-pause.
12874 2012-03-19 Kenichi Handa <handa@m17n.org>
12876 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12877 it fit in a valid range (Bug#11003).
12879 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12881 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12882 that is not from display property, accept the row as a "cursor
12883 row" if one of the string's character has a non-nil `cursor'
12884 property. Fixes cursor positioning when there are newlines in
12885 overlay strings, e.g. in icomplete.el. (Bug#11035)
12887 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12889 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12891 2012-03-12 Chong Yidong <cyd@gnu.org>
12893 * eval.c (inhibit_lisp_code): Rename from
12894 inhibit_window_configuration_change_hook; move from window.c.
12896 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12897 * window.c (run_window_configuration_change_hook)
12898 (syms_of_window): Callers changed.

12904 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12906 2012-03-10 Chong Yidong <cyd@gnu.org>
12908 * frame.c (other_visible_frames): Don't assume the selected frame
12909 is visible (Bug#10955).

12917 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12918 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12921 2012-03-03 Glenn Morris <rgm@gnu.org>
12923 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12925 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12927 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12928 position past the first glyph_row that ends at ZV. (Bug#10902)
12929 (redisplay_window, next_element_from_string): Fix typos in
12931 (redisplay_window): Pass to move_it_vertically the margin in
12932 pixels, not in screen lines.
12934 2012-03-02 Glenn Morris <rgm@gnu.org>
12936 * buffer.c (buffer-list-update-hook): Doc fix.
12938 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12940 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12941 push_it before setting up the iterator for the first overlay
12942 string, even if we have an empty string loaded.
12943 (next_overlay_string): If there's an empty string on the iterator
12944 stack, pop the stack. (Bug#10903)
12946 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12948 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12949 Suggested by Stefan Monnier in
12950 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12951 * alloc.c (widen_to_Lisp_Object): New static function.
12952 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12953 and widening them to Lisp_Objects. This would work even if
12954 USE_LSB_TAG is defined and wide integers are used, which might
12955 happen in a future version of Emacs.
12957 2012-02-25 Chong Yidong <cyd@gnu.org>
12959 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12962 * xselect.c (Fx_selection_exists_p): Doc fix.
12963 (x_clipboard_manager_save_all): Print an informative message
12964 before saving to clipboard manager.
12966 2012-02-24 Chong Yidong <cyd@gnu.org>
12968 * keyboard.c (process_special_events): Handle all X selection
12969 requests in kbd_buffer, not just the next one (Bug#8869).
12971 2012-02-23 Chong Yidong <cyd@gnu.org>
12973 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12974 call when setting menu-bar-lines and tool-bar-lines parameters.
12975 (unwind_create_frame_1): New helper function.
12977 * window.c (inhibit_window_configuration_change_hook): New var.
12978 (run_window_configuration_change_hook): Obey it.
12979 (syms_of_window): Initialize it.
12981 2012-02-22 Chong Yidong <cyd@gnu.org>
12983 * xterm.c (x_draw_image_relief): Add missing type check for
12984 Vtool_bar_button_margin (Bug#10743).
12986 2012-02-21 Chong Yidong <cyd@gnu.org>
12988 * fileio.c (Vfile_name_handler_alist): Doc fix.
12990 * buffer.c (Fget_file_buffer): Protect against invalid file
12991 handler return value.
12993 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
12995 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
12996 when computing $valmask.
12998 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12999 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13000 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13001 It's useless in that case, and it can cause problems on hosts
13002 that allocate halves of EMACS_INT values separately.
13003 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13004 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13005 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13006 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13007 it avoids undefined behavior on hosts where shifting right by more
13008 than the word width has undefined behavior.
13010 2012-02-19 Chong Yidong <cyd@gnu.org>
13012 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13013 (Funhandled_file_name_directory, Ffile_name_as_directory)
13014 (Fdirectory_file_name, Fexpand_file_name)
13015 (Fsubstitute_in_file_name): Protect against invalid file handler
13016 return values (Bug#10845).
13018 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13020 * .gdbinit (pitx): Fix incorrect references to fields of the

13030 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13032 2012-02-15 Chong Yidong <cyd@gnu.org>
13034 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13035 marked as special. Also, starting docstrings with * is obsolete.

13048 * keymap.c (Fsingle_key_description): Handle char ranges.
13050 2012-02-12 Chong Yidong <cyd@gnu.org>
13052 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13053 as that creates a dangerous corner case.
13055 * window.c (Fdelete_window_internal): Invalidate the mouse
13056 highlight (Bug#9904).
13058 2012-02-12 Glenn Morris <rgm@gnu.org>

13061 (Fx_get_selection_internal, Fx_disown_selection_internal)
13062 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13063 * nsselect.m (Fx_own_selection_internal)
13064 (Fx_disown_selection_internal, Fx_selection_exists_p)
13065 (Fx_selection_owner_p, Fx_get_selection_internal):
13066 Sync docs and argument specs with the xselect.c versions.
13068 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13070 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

13088 2012-02-07 Chong Yidong <cyd@gnu.org>
13090 * buffer.c (Fbuffer_local_variables)
13091 (buffer_lisp_local_variables): Handle unbound vars correctly;
13092 don't let Qunbound leak into Lisp.
13094 2012-02-07 Glenn Morris <rgm@gnu.org>
13096 * image.c (Fimagemagick_types): Doc fix.
13098 * image.c (imagemagick-render-type): Change it from a lisp object
13099 to an integer. Move the doc here from the lisp manual.
13100 Treat all values not equal to 0 the same.

13112 2012-02-04 Chong Yidong <cyd@gnu.org>
13114 * nsterm.m: Declare a global (Bug#10694).
13116 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13118 * w32.c (get_emacs_configuration_options):
13119 Include --enable-checking, if specified, in the return value.
13121 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13123 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13124 after rounding frame sizes. (Bug#9723)

13128 * keyboard.c (adjust_point_for_property): Don't position point
13129 before BEGV. (Bug#10696)
13131 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13133 Handle overflow when computing char display width (Bug#9496).
13134 * character.c (char_width): Return EMACS_INT, not int.
13135 (char_width, c_string_width): Check for overflow when
13136 computing the width; this is possible now that individual
13137 characters can have unbounded width. Problem introduced
13138 by merge from Emacs 23 on 2012-01-19.
13140 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

13155 2012-02-02 Kenichi Handa <handa@m17n.org>
13157 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13158 0, do not call append_composite_glyph.
13160 2012-02-02 Kenichi Handa <handa@m17n.org>
13162 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13164 (x_produce_glyphs): If the component of a composition is a null
13165 string, set it->pixel_width to 1 to avoid zero-width glyph.
13167 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13169 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13170 first 2 arguments are identical. This makes inserting large
13171 output from a subprocess an order of magnitude faster on
13172 MS-Windows, where all sbrk'ed memory is always contiguous.
13174 2012-01-31 Glenn Morris <rgm@gnu.org>
13176 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13212 2012-01-21 Chong Yidong <cyd@gnu.org>
13214 * floatfns.c (Fcopysign): Make the second argument non-optional,
13215 since nil is not allowed anyway.
13217 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>

13230 * character.c (char_width): New function.
13231 (Fchar_width, c_string_width, lisp_string_width):
13232 Use char_width (Bug#9496).

13254 he end column for display of highlight that ends on a newline
13257 2012-01-11 Glenn Morris <rgm@gnu.org>
13259 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
13260 from load-path also when installation-directory is nil. (Bug#10208)
13262 2012-01-10 Glenn Morris <rgm@gnu.org>
13264 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
13266 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
13267 Update template values to be closer to their typical values these days.
13269 2012-01-09 Eli Zaretskii <eliz@gnu.org>
13271 * xdisp.c (rows_from_pos_range): Accept additional argument
13272 DISP_STRING, and accept any glyph in a row whose object is that
13273 string as eligible for mouse highlight. Fixes mouse highlight of
13274 display strings from overlays. (Bug#10464)
13276 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
13278 emacs: fix an auto-save permissions race condition (Bug#10400)
13279 * fileio.c (auto_saving_dir_umask): New static var.
13280 (Fmake_directory_internal): Use it.
13281 (do_auto_save_make_dir): Set it, instead of invoking chmod after
13282 creating the directory. The old code temporarily assigns
13283 too-generous permissions to the directory.
13284 (do_auto_save_eh): Clear it.
13285 (Fdo_auto_save): Catch all errors, not just file errors, so
13286 that the var is always cleared.
13288 2012-01-07 Eli Zaretskii <eliz@gnu.org>
13290 * search.c (scan_buffer): Pass character positions to
13291 know_region_cache, not byte positions. (Bug#6540)

13795 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13796 to 4 (xorl, subq, cmpq, setbe).
13797 * alloc.c (pure): Always extern now, since that's the
13798 VIRT_ADDR_VARIES behavior.
13799 (PURE_POINTER_P): Use a single comparison, not two, for
13800 consistency with the new puresize.h.
13801 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13802 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13810 behave as if the cursor position were at the window margin.
13812 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13813 and the cursor position is out of bounds, behave as if the cursor
13814 position were at the window margin. (Bug#10075)

13885 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13887 * xdisp.c (display_line): Move the call to
13888 highlight_trailing_whitespace before the call to
13889 compute_line_metrics, since the latter needs to see the final
13890 faces of all the glyphs to compute ROW's hash value.
13891 Fixes assertion violations in row_equal_p. (Bug#10035)
13893 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13895 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

13900 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13901 with user-defined heap size. Bump the default size of the temacs

13954 Avoid some portability problems by eschewing 'extern inline' functions.
13955 The trivial performance wins aren't worth the portability hassles; see
13956 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13958 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14024 * xmenu.c (cleanup_widget_value_tree): New function.
14025 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14032 (window_box_width, window_box_left, window_box_left_offset)
14033 (window_box_right, window_box_right_offset): Declare extern.
14034 Otherwise, these inline functions do not conform to C99 and
14035 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14036 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14037 * intervals.c (adjust_intervals_for_insertion)

14040 (static_offset_intervals): Remove.
14041 (offset_intervals): Rewrite using the old contents of
14042 static_offset_intervals. The old version didn't conform to C99
14043 because an extern inline function contained a reference to an
14044 identifier with static linkage.

14097 (unwind_create_frame): New function (Bug#9943).
14098 (Fx_create_frame): Restructure code to be more similar to the one in
14099 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

14247 possible random value that matches one of those tested as
14248 condition to clear the mouse face.
14250 2011-10-28 Chong Yidong <cyd@gnu.org>
14252 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14254 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14256 * window.c (make_window): Initialize phys_cursor_on_p.
14258 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14260 * lisp.h (struct Lisp_Symbol): Update comments.
14262 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14264 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14266 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14268 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14269 <oslsachem@gmail.com> for helping to debug this.
14271 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14272 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14273 (g_b_init_get_glyph_outline_w): New static variables.
14274 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14275 (GetGlyphOutlineW_Proc): New typedefs.
14276 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14277 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14279 (w32font_open_internal, compute_metrics):
14280 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14281 instead of calling the "wide" APIs directly.
14283 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14285 * w32.h (syms_of_w32font): Add prototype.
14287 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14289 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14290 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14291 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14292 (Fmove_to_window_line): Doc fix.
14294 2011-10-27 Chong Yidong <cyd@gnu.org>
14296 * process.c (make_process): Set gnutls_state to NULL.
14298 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14299 non-NULL, regardless of GNUTLS_INITSTAGE.
14300 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14301 an error. Set process slots as soon as we allocate them.
14303 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14305 2011-10-27 Chong Yidong <cyd@gnu.org>
14307 * gnutls.c (emacs_gnutls_deinit): New function.
14308 Deallocate credentials structures as well as calling gnutls_deinit.
14309 (Fgnutls_deinit, Fgnutls_boot): Use it.
14311 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14312 (deactivate_process): Call emacs_gnutls_deinit.
14314 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14316 * image.c (x_create_x_image_and_pixmap):
14317 * w32.c (sys_rename, w32_delayed_load):
14318 * w32font.c (fill_in_logfont):
14319 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14321 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14323 * w32fns.c (w32_default_color_map): New function,
14324 extracted from Fw32_default_color_map.
14325 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14327 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14329 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14331 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14333 * keyboard.c (test_undefined): New function (bug#9751).
14334 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14336 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14338 * sysdep.c (init_sys_modes): Fix the check for the controlling
14339 terminal (Bug#6649).
14341 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14343 * dispextern.h (struct bidi_it): New member next_en_type.
14345 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14346 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14347 current character, check also for next_en_type being WEAK_EN.
14348 (bidi_resolve_weak): Don't enter the expensive loop if the current
14349 position is before next_en_pos. Record the bidi type of the first
14350 non-ET, non-BN character we find, in addition to its position.
14351 (bidi_level_of_next_char): Invalidate next_en_type when
14352 next_en_pos is over-stepped.
14354 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14356 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14357 * editfns.c: Rewrite current-time-zone so that it invokes
14358 the equivalent of (format-time-string "%Z") to get the time zone name.
14359 This fixes a bug when the time zone name contains characters that
14360 need converting from the system time locale to Emacs internal format.
14361 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14362 that patch fixed format-time-string to do the conversion, but
14363 I forgot to fix current-time-zone.
14364 (format_time_string): New function, containing most of
14365 what Fformat_time_string used to contain.
14366 (Fformat_time_string): Rewrite in terms of format_time_string.
14367 This doesn't change this function's behavior.
14368 (current-time-zone): Rewrite to use format_time_string.
14369 This fixes the bug reported by Michael Schierl in
14370 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14371 Jason Rumney's 2007-06-07 change worked around this bug, but
14373 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14375 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14377 * xdisp.c (start_display): If the character at POS is displayed
14378 via a display vector, reset IT->current.dpvec_index to zero.
14379 (try_window_reusing_current_matrix): If a line ends in a display
14380 vector or the next line starts in a display vector, continue
14381 redrawing the window even though the character position of
14382 start_row was reached.
14385 2011-10-18 Chong Yidong <cyd@gnu.org>
14387 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14388 with nobreak-char-display too.
14390 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14392 Fix part 3 of bug#9771.
14393 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14394 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14395 non-neutral characters if the current character is a paragraph
14396 separator (a.k.a. Newline). This avoids running the same
14397 expensive loop twice, once when we consume the preceding newline
14398 and the other time when the line actually needs to be displayed.
14399 Avoid the loop when we see neutrals on the base embedding level
14400 following a character whose directionality is the same as the
14401 paragraph's. This avoids running the expensive loop when a line
14402 ends in a long sequence of neutrals, like control characters.
14403 Add assertion against STRONG_AL type. Slightly rearrange code
14404 that determines the type of a neutral given the first non-neutral
14406 (bidi_level_of_next_char): Set next_en_pos to zero when
14407 invalidating its info.
14409 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14411 * xdisp.c (push_display_prop): Determine whether to record string
14412 or buffer position by IT->string, not by IT->method. Allow
14413 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14414 (move_it_vertically_backward): Don't look for character position
14415 immediately after the newline when in a continuation line.
14418 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14420 * window.c (coordinates_in_window): Rewrite and delabelize
14421 vertical border check. (Bug#5357) (Bug#9618)
14423 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14425 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14426 errors in XSetWindowBorder (bug#9310).
14428 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14430 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14431 avoid crash when xmalloc overrun checking is enabled.
14433 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14435 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14436 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14437 cursor motion with <left> and <right> arrow keys.
14439 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14440 some callers set that themselves.
14442 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14444 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14445 display string and the previous row comes from the same string and
14446 is empty. (Bug#9739) (Bug#9738)
14448 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14450 * doc.c (get_doc_string): Encode file name (bug#9735).
14452 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14454 * bidi.c (bidi_level_of_next_char):
14455 * xdisp.c (get_visually_first_element): Remove old incorrect
14456 comments regarding the Unicode Line Separator character.
14458 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14460 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14462 * alloc.c (Fgc_status): Do not access beyond zombies array
14463 boundary if nzombies > MAX_ZOMBIES.
14464 * alloc.c (dump_zombies): Add missing format specifier.
14466 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14468 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14469 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14471 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14472 Some packages use them to denote characters with modifiers.
14474 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14476 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14477 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14478 matching a pp-number. Rename parameter var to var1.
14480 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14482 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14484 2011-10-08 Glenn Morris <rgm@gnu.org>
14486 * callint.c (Fcall_interactively): Give a more explicit error for the
14487 'c' case with a non-character input. (Bug#8479)
14489 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14491 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14493 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14494 lines that are hscrolled on the left.
14496 * dispnew.c (buffer_posn_from_coords): Account for a possible
14497 presence of header-line. (Bug#4426)
14499 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14501 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14502 Don't advertise functionality which we discourage or doesn't work.
14504 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14506 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14507 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14508 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14509 this makes Emacs dump core during garbage collection on rare
14510 occasions. sizeof is obviously inferior to offsetof here, so
14511 stick with offsetof.
14512 (GC_POINTER_ALIGNMENT): New macro.
14513 (mark_memory): Omit 3rd (offset) arg; caller changed.
14514 Don't assume EMACS_INT alignment is the same as pointer alignment.
14516 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14518 * keyboard.c (read_key_sequence_remapped): New var.
14519 (read_key_sequence): Compute remapping in the right buffer.
14520 (command_loop_1): Use read_key_sequence's remapping directly.
14522 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14524 * dired.c (file_name_completion): Don't expand file name.
14525 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14526 before checking file name handler.
14528 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14529 they've been requested explicitly (bug#9591).
14531 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14533 * keymap.c (Fsingle_key_description): Use make_specified_string
14534 instead of build_string to build string from push_key_description.
14537 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14539 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14540 This fixes a Y2038 bug on 64-bit hosts.
14541 * buffer.c (reset_buffer):
14542 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14543 (Fclear_buffer_auto_save_failure):
14544 Use 0, not -1, to represent an unset failure time, since time_t
14545 might not be signed.
14547 Remove dependency on glibc malloc internals.
14548 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14549 Move back here from lisp.h, but with their new implementations.
14550 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14551 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14552 * charset.c (charset_table_init): New static var.
14553 (syms_of_charset): Use it instead of xmalloc. This removes a
14554 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14555 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14556 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14557 Move back to alloc.c.
14558 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14559 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14561 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14563 * nsterm.m (windowDidResize): Call x_set_window_size only when
14564 ns_in_resize is true. Otherwise set pixelwidth/height and
14565 call change_frame_size (Bug#9628).
14567 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14569 Port --enable-checking=all to Fedora 14 x86-64.
14570 * charset.c (syms_of_charset): Also account for glibc malloc's
14571 internal overhead when calculating the initial malloc maximum.
14573 Port --enable-checking=all to Fedora 14 x86.
14574 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14576 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14577 (overrun_check_realloc, overrun_check_free):
14578 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14579 That way, xmalloc returns a properly-aligned pointer even if
14580 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14581 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14582 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14583 into account when calculating the initial malloc maximum.
14584 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14585 Move here from alloc.c, so that charset.c can use it too.
14586 Properly align; the old code wasn't right for common 32-bit hosts
14587 when configured with --enable-checking=all.
14588 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14589 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14591 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14593 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14596 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14598 * xdisp.c (compute_display_string_end): If there's no display
14599 string at CHARPOS, return -1.
14601 * bidi.c (bidi_fetch_char): When compute_display_string_end
14602 returns a negative value, treat the character as a normal
14603 character not covered by a display string. (Bug#9624)
14605 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14607 * lread.c (Fread_from_string): Fix typo in docstring.
14609 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14611 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14612 newline, reseat the iterator instead of bidi-iterating there one
14613 character at a time. (Bug#9610)
14614 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14615 TO_CHARPOS if the bidi iterator is at base embedding level.
14617 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14619 * lread.c (readevalloop): Use correct code for NBSP.
14620 (read1): Likewise. (Bug#9608)
14622 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14624 * dbusbind.c (Fdbus_register_signal): When service is not
14625 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14627 2011-09-25 Glenn Morris <rgm@gnu.org>
14629 * buffer.c (truncate-lines): Doc fix.
14631 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14633 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14634 (Fset_window_next_buffers): Doc fix.
14636 2011-09-24 Glenn Morris <rgm@gnu.org>
14638 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14640 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14642 Fix minor problems found by static checking.
14643 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14644 * indent.c (Fvertical_motion): Fix == vs = typo.
14646 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14648 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14649 Default value is now t. Doc fix.
14651 * indent.c (Fvertical_motion): Compute and apply the overshoot
14652 logic when moving up, not only when moving down. Fix the
14653 confusing name and values of the it_overshoot_expected variable;
14654 logic changes accordingly. (Bug#9254) (Bug#9549)
14656 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14657 CHARPOS is covered by a display string which includes newlines.
14658 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14659 is covered by a display string with embedded newlines.
14661 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14663 * dbusbind.c (Fdbus_register_signal): Add match rule to
14664 Vdbus_registered_objects_table. (Bug#9581)
14665 (Fdbus_register_method, Vdbus_registered_objects_table):
14668 2011-09-24 Jim Meyering <meyering@redhat.com>
14670 do not ignore write error for any output size
14671 The previous change was incomplete.
14672 While it makes emacs --batch detect the vast majority of stdout
14673 write failures, errors were still ignored whenever the output size is
14674 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14675 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14676 && echo FAIL: ignored write error
14677 FAIL: ignored write error
14678 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14679 && echo FAIL: ignored write error
14680 FAIL: ignored write error
14681 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14683 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14685 * emacs.c (Fkill_emacs): In noninteractive mode exit
14686 non-successfully if a write error occurred on stdout. (Bug#9574)
14688 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14690 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14693 * dispextern.h (struct it): Update the comment documenting what
14696 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14698 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14699 a display string, extend search for cursor position to end of row.
14700 (find_row_edges): If the row ends in a newline from a display
14701 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14702 Handle the case of a display string with multiple newlines.
14703 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14704 non-empty line. Fixes confusing cursor motion with arrow keys at
14705 the beginning of a line that starts with whitespace.
14707 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14709 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14712 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14714 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14715 boolean (Bug#9154).
14717 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14719 * xdisp.c (display_line): Record maximum and minimum buffer
14720 positions even if no glyphs were produced (e.g., by a zero-width
14721 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14722 buffer positions that will be removed from the glyph row because
14724 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14725 column is beyond frame width: don't subtract 1 "pixel" when
14726 computing width of the stretch.
14727 (reseat_at_next_visible_line_start): Undo the change made on
14728 2011-09-17 that saved paragraph information and restored it after
14729 the call to `reseat'. (Bug#9545)
14731 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14733 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14734 and turn window cursor on if cleared (Bug#9415).
14736 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14738 * search.c (boyer_moore): Take unibyte characters from pattern
14739 literally. (Bug#9458)
14741 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14743 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14745 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14747 Fix minor problem found by static checking.
14748 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14749 initialized, to pacify gcc -Wuninitialized.
14751 * fileio.c: Report proper errno when syscall falls.
14752 (Finsert_file_contents): Save and restore errno,
14753 so that report_file_error outputs the correct diagnostic.
14754 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14756 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14758 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14760 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14762 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14763 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14765 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14767 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14768 about the current paragraph and restore it after the call to reseat.
14770 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14771 (bidi_find_paragraph_start): Search back for paragraph beginning
14772 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14773 (bidi_move_to_visually_next): Only trigger paragraph-related
14774 computations when the last character is a newline or at EOB, not
14775 just any NEUTRAL_B. (Bug#9470)
14777 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14778 truncated lines if point is covered by a display string. (Bug#9524)
14780 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14782 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14783 (cons_to_x_long): New function.
14784 (lisp_data_to_selection_data): Use it. Correct the test for
14785 short-versus-long data; it was negated. Break out of vector
14786 loop, for efficiency, when a long datum is discovered.
14788 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14790 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14792 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14794 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14795 GCC PR/17406) by declaring this function with external scope.
14797 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14799 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14800 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14802 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14804 * editfns.c (Fformat): Correctly handle text properties on "%%".
14806 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14808 * xterm.c (x_draw_composite_glyph_string_foreground):
14809 * w32term.c (x_draw_composite_glyph_string_foreground):
14810 * term.c (encode_terminal_code):
14811 * composite.c (composition_update_it, get_composition_id):
14812 * xdisp.c (get_next_display_element)
14813 (fill_composite_glyph_string): Add comments about special meaning
14814 of TAB characters in a composition.
14816 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14818 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14819 This occurs when processing a multibyte format.
14820 Problem reported by Wolfgang Jenker.
14822 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14824 * xdisp.c (try_cursor_movement): Only check for exact match if
14825 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14827 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14829 Remove unused external symbols.
14830 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14831 * xdisp.c (calc_pixel_width_or_height): Now static.
14832 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14833 * indent.c (check_display_width):
14834 * w32term.c: Fix comment to match code.
14835 * xterm.c, xterm.h (x_catching_errors): Remove.
14837 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14839 * xselect.c: Use signed conversions more consistently (Bug#9498).
14840 (selection_data_to_lisp_data): Assume incoming selection data are
14841 signed integers, not unsigned. This is to be consistent with
14842 outgoing selection data, which was modified to use signed integers
14843 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14844 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14845 expects long, not unsigned long.
14847 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14849 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14850 computation of loop end. Reported by Johan Bockgård
14853 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14855 * frame.c (Fother_visible_frames_p): Function deleted.
14857 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14859 * indent.c (compute_motion): Process display vector front to back
14860 rather than the other way around. (Bug#2496)
14862 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14864 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14866 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14868 * minibuf.c (Fread_from_minibuffer): Doc fix.
14870 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14872 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14873 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14875 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14877 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14878 value for non-existent files.
14880 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14882 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14883 set its "size" to -1. This will set the modtime_size field of
14884 the corresponding buffer to -1, which is what
14885 verify-visited-file-modtime expects for files that do not exist.
14888 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14890 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14892 * lisp.h: ... from here. push_key_description is no longer
14893 defined in keyboard.c, so its declaration should not be in
14894 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14895 logically belongs with push_key_description.
14897 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14899 * buffer.h: Include <sys/types.h> instead of <time.h>.
14900 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14901 Problem reported by Herbert J. Skuhra.
14903 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14905 * xml.c (parse_region): Make the parsing work for
14906 non-comment-starting XML files again (bug#9144).
14908 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14910 * image.c (gif_load): Fix calculation of bottom and right corner.
14913 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14915 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14916 redisplay in small windows.
14918 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14920 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14922 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14924 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14925 Operate on live windows only.
14927 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14929 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14931 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14933 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14934 only under bidi iteration.
14936 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14938 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14940 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14942 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14943 Without this fix, the command to link temacs failed due to an
14944 undefined symbol __builtin_isnan. This is because
14945 /usr/include/iso/math_c99.h #defines isnan(x) to
14946 __builtin_isnan(x), but the bundled gcc, which identifies itself
14947 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14949 * floatfns.c (isnan): #undef, and then #define to a clone of
14951 (Fisnan): Always define, since it's always available now.
14952 (syms_of_floatfns): Always define isnan at the Lisp level.
14954 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14956 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14958 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14960 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14961 The previous code assumed that file offsets (off_t values) fit in
14962 EMACS_INT variables, which is not true on typical 32-bit hosts.
14963 The code messed up by falsely reporting buffer overflow in cases
14964 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14965 when "big" contains more than 2**29 bytes, even though this
14966 inserts just one byte and does not overflow the buffer.
14967 (Finsert_file_contents): Store file offsets as off_t
14968 values, not as EMACS_INT values. Check for overflow when
14969 converting between EMACS_INT and off_t. When checking for
14970 buffer overflow or for overlap, take the offsets into account.
14971 Don't use EMACS_INT for small values where int suffices.
14972 When checking for overlap, fix a typo: ZV was used where
14973 ZV_BYTE was intended.
14974 (Fwrite_region): Don't assume off_t fits into 'long'.
14975 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14977 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14979 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14981 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14983 sprintf-related integer and memory overflow issues (Bug#9412).
14985 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14986 (esprintf, exprintf, evxprintf): New functions.
14987 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14988 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14989 (modify_event_symbol): Do not assume that the length of
14990 name_alist_or_stem is safe to alloca and fits in int.
14991 (Fexecute_extended_command): Likewise for function name and binding.
14992 (Frecursion_depth): Wrap around reliably on integer overflow.
14993 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14994 since some callers pass EMACS_INT values.
14995 (Fsingle_key_description): Don't crash if symbol name contains more
14996 than MAX_ALLOCA bytes.
14997 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14998 (get_minibuffer): Arg is now EMACS_INT, not int.
14999 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15000 (esprintf, exprintf, evxprintf): New decls.
15001 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15003 * dbusbind.c (signature_cat): New function.
15004 (xd_signature, Fdbus_register_signal):
15005 Do not overrun buffer; instead, report string overflow.
15007 * dispnew.c (add_window_display_history): Don't overrun buffer.
15008 Truncate instead; this is OK since it's just a log.
15010 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15011 even if the time zone offset is outlandishly large.
15012 Don't mishandle offset == INT_MIN.
15014 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15015 when creating daemon; the previous buffer-overflow check was incorrect.
15017 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15018 which has the guts of the old verror function.
15020 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15021 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15023 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15024 (font_unparse_xlfd): Don't blindly alloca long strings.
15025 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15026 fits in int, when using sprintf. Use single snprintf to count
15027 length of string rather than counting it via multiple sprintfs;
15028 that's simpler and more reliable.
15029 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15030 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15031 sprintf, in case result does not fit in int.
15033 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15034 (fontset_from_font): Print it.
15036 * frame.c (tty_frame_count): Now printmax_t, not int.
15037 (make_terminal_frame, set_term_frame_name): Print it.
15038 (x_report_frame_params): In X, window IDs are unsigned long,
15039 not signed long, so print them as unsigned.
15040 (validate_x_resource_name): Check for implausibly long names,
15041 and don't assume name length fits in 'int'.
15042 (x_get_resource_string): Don't blindly alloca invocation name;
15043 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15046 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15047 (xg_check_special_colors, xg_set_geometry):
15048 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15050 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15051 Use esprintf, not sprintf, in case result does not fit in int.
15053 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15054 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15055 it as a large positive number.
15056 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15057 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15059 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15060 in case result does not fit in int.
15062 * print.c (float_to_string): Detect width overflow more reliably.
15063 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15064 buffer overrun. Don't assume list length fits in 'int'. Treat
15065 print length of 0 as 0, not as infinity; to be consistent with other
15066 uses of print length in this function. Don't overflow print length
15067 index. Don't assume hash table size fits in 'long', or that
15068 vectorlike size fits in 'unsigned long'.
15070 * process.c (make_process): Use printmax_t, not int, to format
15071 process-name gensyms.
15073 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15075 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15076 to avoid potential buffer overrun.
15078 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15079 if X resource line is longer than 512 bytes.
15081 * xfns.c (x_window): Make sprintf buffer a bit bigger
15082 to avoid potential buffer overrun.
15084 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15086 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15088 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15090 Integer overflow fixes for scrolling, etc.
15091 Without these, Emacs silently mishandles large integers sometimes.
15092 For example, "C-u 4294967297 M-x recenter" was treated as if
15093 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15095 * xdisp.c (try_window_id): Check Emacs fixnum range before
15096 converting to 'int'.
15098 * window.c (window_scroll_line_based, Frecenter):
15099 Check that an Emacs fixnum is in range before assigning it to 'int'.
15100 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15101 values converted from Emacs fixnums.
15102 (Frecenter): Don't wrap around a line count if it is out of 'int'
15103 range; instead, treat it as an extreme value.
15104 (Fset_window_configuration, compare_window_configurations):
15105 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15107 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15108 that can exceed INT_MAX. Check that EMACS_INT value is in range
15109 before assigning it to the (possibly-narrower) index.
15110 (match_limit): Don't assume that a fixnum can fit in 'int'.
15112 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15115 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15116 (Fvertical_motion): Don't wrap around LINES values that don't fit
15117 in 'int'. Instead, treat them as extreme values. This is good
15118 enough for windows, which can't have more than INT_MAX lines anyway.
15120 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15122 * Require libxml/parser.h to avoid compilation warning.
15124 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15126 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15127 since this reportedly can destroy thread storage.
15129 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15131 * syntax.c (find_defun_start): Update all cache variables if
15132 exiting early (Bug#9401).
15134 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15136 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15138 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15139 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15140 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15142 * term.c (tty_append_glyph): New function.
15143 (produce_stretch_glyph): Static function and its prototype deleted.
15145 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15148 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15150 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15151 when checking :margin (Bug#9390).
15152 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15153 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15154 so that the name doesn't mislead. All uses changed.
15156 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15158 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

15166 the first character in the line after the newline.
15168 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15170 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15171 (ccl_driver): Do not generate an out-of-range pointer.
15172 (Fccl_execute_on_string): Remove unnecessary check for
15173 integer overflow, noted by Stefan Monnier in
15174 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15175 Remove a FIXME that didn't need fixing.
15176 Simplify the newly-introduced buffer reallocation code.
15178 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15180 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15182 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15184 Integer and memory overflow issues (Bug#9196).
15186 * doc.c (get_doc_string): Rework so that
15187 get_doc_string_buffer_size is the actual buffer size, rather than
15188 being 1 less than the actual buffer size; this makes xpalloc more
15191 * image.c (x_allocate_bitmap_record, cache_image):
15192 * xselect.c (Fx_register_dnd_atom):
15193 Simplify previous changes by using xpalloc.
15195 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15196 since either will do and ptrdiff_t is convenient with xpalloc.
15198 * charset.c (charset_table_size)
15199 (struct charset_sort_data.priority): Now ptrdiff_t.
15200 (charset_compare): Don't overflow if priorities differ greatly.
15201 (Fsort_charsets): Don't assume list length fits in int.
15202 Check for size-calculation overflow when allocating sort data.
15203 (syms_of_charset): Allocate an initial charset table that is
15204 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15206 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15208 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15209 The actual value is always <= INT_MAX, and leaving it unsigned made
15210 overflow checking harder.
15212 * dispextern.h (struct glyph_matrix.rows_allocated)
15213 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15214 with xpalloc. The values are still always <= INT_MAX.
15216 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15218 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15219 (SAFE_NALLOCA): New macro.
15221 * region-cache.c (struct boundary.pos, find_cache_boundary)
15222 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15223 (set_cache_region, invalidate_region_cache)
15224 (revalidate_region_cache, know_region_cache, region_cache_forward)
15225 (region_cache_backward, pp_cache):
15226 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15227 so that ptrdiff_t * can be passed to xpalloc.
15228 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15229 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15230 (pp_cache): Don't assume cache_len fits in int.
15231 * region-cache.h: Adjust extern decls to match.
15233 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15234 EMACS_INT, since either will do, for xpalloc.
15236 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15237 (xnmalloc, xnrealloc, xpalloc): New functions.
15239 * bidi.c (bidi_shelve_header_size): New constant.
15240 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15241 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15243 * bidi.c (bidi_cache_shrink):
15244 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15246 Don't update size of array until after memory allocation succeeds,
15247 because xmalloc/xrealloc may not return.
15248 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15249 now that we have proper integer overflow checking.
15250 (record_overlay_string, overlay_strings): Catch overflows when
15251 calculating size of overlay_str_buf.
15253 * callproc.c (Fcall_process): Check for size overflow when
15254 calculating size of args2.
15255 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15256 Normally we prefer signed values, but sticking with ptrdiff_t would
15257 require adding more-complicated checks.
15259 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15260 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15261 Redo buffer-overflow calculations to avoid integer overflow.
15262 Add a FIXME comment where memory seems to be over-allocated.
15264 * character.c (Fstring): Check for size-calculation overflow.
15266 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15267 unnecessary integer overflow. Check for size overflow.
15268 (encode_coding_object): Don't update size until xmalloc succeeds.
15270 * composite.c (get_composition_id): Check for overflow in glyph
15271 length calculations.
15273 Integer and memory overflow fixes for display code.
15274 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15275 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15276 (scrolling_window): Check for overflow in size calculations.

15288 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15289 (get_doc_string): Check for size calculation overflow.
15290 Don't update size until allocation succeeds.
15291 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15292 EMACS_INT, where ptrdiff_t will do.
15293 (Fsubstitute_command_keys): Check for string overflow.
15295 * editfns.c (set_time_zone_rule): Don't assume environment length
15297 (message_length): Now ptrdiff_t, not int.
15298 (Fmessage_box): Don't update size until allocation succeeds.
15299 Don't assume message length fits in int.
15300 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15302 * emacs.c (main): Do not reallocate argv, since there is a null at
15303 the end that can be overwritten, and this way there's no need to
15304 worry about size-calculation overflow.
15305 (sort_args): Check for size-calculation overflow.
15307 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15309 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15311 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15312 (x_set_scroll_bar_width, x_figure_window_size):
15313 Check for integer overflow.
15314 (x_set_alpha): Do not assume XINT fits in int.
15316 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15317 This is for the members text_lines, text_cols, total_lines, total_cols,
15318 where the system imposes an 'int' limit.
15320 * fringe.c (Fdefine_fringe_bitmap):
15321 Don't update size until alloc works.
15323 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15324 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15326 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15327 Check for size-calculation overflow.
15328 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15329 do, as we prefer signed integers.
15330 (id_to_widget.max_size, id_to_widget.used)
15331 (xg_store_widget_in_map, xg_remove_widget_from_map)
15332 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15333 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15334 Use and return ptrdiff_t, not int.
15335 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15336 * gtkutil.h: Change prototypes to match the above.
15338 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15339 are duplicate now that they've been promoted to lisp.h.
15340 (x_allocate_bitmap_record, x_alloc_image_color)
15341 (make_image_cache, cache_image, xpm_load):
15342 Don't update size until alloc is done.

15353 Use ptrdiff_t, not int, to count maps.
15354 (read_char_minibuf_menu_prompt): Check for overflow in size
15355 calculations. Don't update size until allocation succeeds.
15356 Redo calculations to avoid overflow.
15357 * keyboard.h: Change prototypes to match the above.
15359 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

15385 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15386 for command line length. Do not attempt to address one before the
15387 beginning of an array, as that's not portable.
15389 * term.c (max_frame_lines): Remove; unused.
15390 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15392 (encode_terminal_code, calculate_costs): Check for size
15393 calculation overflow.

15399 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15400 subtracting pointers.

15415 Use ptrdiff_t, not int, for sizes.
15416 (Finternal_make_lisp_face, cache_face):
15417 Check for size calculation overflow.
15418 (cache_face): Treat size calculation overflows as if they were
15419 memory exhaustion (the usual treatment), rather than aborting.
15421 * xfns.c (x_encode_text, x_set_name_internal)
15422 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15423 sizes, since they can exceed INT_MAX in size. Check for size

15427 (xg_select): Check for size calculation overflow.
15428 Don't update size until alloc done.
15430 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15431 as sprintf is limited to int lengths.
15433 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15434 (X_LONG_MIN): New macros.
15435 Use them to make the following changes clearer.
15436 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15437 This change doesn't affect the value now, but it may help remind
15438 future maintainers not to raise the value too much later.
15439 (SELECTION_QUANTUM): Remove, replacing with ...
15440 (selection_quantum): ... new function, which avoids overflow.
15442 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15443 assumption that selection length fits in 'int'.

15456 (lisp_data_to_selection_data, x_property_data_to_lisp):

15460 Don't store size until memory allocation succeeds.
15461 (x_get_window_property): Plug memory leak on memory exhaustion.
15462 Don't double-block input; malloc is safe here. Don't assume 2**34
15463 - 4 fits in unsigned long. Add an xassert to check
15464 XGetWindowProperty overflow. Be more careful about overflow
15465 calculations, and distinguish size from memory overflow better.
15466 (receive_incremental_selection): When tracing, don't assume
15467 unsigned int is less than INT_MAX.
15468 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15469 harmful) conversions of unsigned short to int.
15470 (lisp_data_to_selection_data): Don't assume that integers
15471 in the range -65535 through -1 fit in an X unsigned short.
15472 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15473 result parameters unless successful. Rely on cons_to_unsigned
15474 to report problems with elements; the old code wasn't right anyway.
15475 (x_check_property_data): Check for int overflow; we cannot use
15476 a wider type due to X limits.
15477 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15479 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

15509 * lisp.h (hash_lookup, hash_put):
15510 * minibuf.c (Ftest_completion):
15511 Use ptrdiff_t for hash table indexes, not int (which is too
15512 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15513 32-bit --with-wide-int hosts).
15515 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15516 Add a FIXME comment about memory leaks.
15517 (syms_of_charset): Don't assume xmalloc returns.

15524 with outlandish widths.
15525 * character.h (sanitize_tab_width): Rename from sanitize_width,
15526 now that we have two such functions. All uses changed.

15538 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
15540 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

15547 exceed limits imposed by XClientMessageEvent, as well as the usual
15548 ptrdiff_t and size_t limits.
15550 * keyboard.c: Overflow, signedness and related fixes.
15551 (make_lispy_movement): Use same integer type in forward decl
15552 that is used in the definition.
15553 (read_key_sequence, keyremap_step):
15554 Change bufsize argument back to int, undoing my 2011-03-30 change.
15555 We prefer signed types, and int is wide enough here.
15556 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15557 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15558 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15559 length, not size_t. Use ptrdiff_t for index, not int.
15560 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15561 possibility of integer overflow.
15563 Overflow, signedness and related fixes for images.

15589 Prefer int to unsigned where either will do.
15590 (tiff_handler): New function, combining the cores of the
15591 old tiff_error_handler and tiff_warning_handler.
15592 This function is rewritten to use vsnprintf and thereby avoid
15593 stack buffer overflows. It uses only the features of vsnprintf
15594 that are common to both POSIX and native Microsoft.
15595 (tiff_error_handler, tiff_warning_handler): Use it.
15596 (tiff_load, gif_load, imagemagick_load_image):
15597 Don't assume :index value fits in 'int'.

15599 (imagemagick_load_image): Check that crop parameters fit into
15600 the integer types that MagickCropImage accepts. Don't assume
15601 Vimagemagick_render_type has a nonnegative value. Don't assume
15602 size_t fits in 'long'.
15603 (gs_load): Use printmax_t to print the widest integers possible.

15617 (handle_single_display_spec): If the display spec is of the form
15618 `(space ...)', and specifies display in the text area, return 2
15620 (try_cursor_movement): Check for the need to scroll more
15621 accurately, and prefer exact match for point under bidi.
15622 Don't advance `row' beyond the last row of the window.

15643 positioning on the newline at EOL of R2L text within L2R
15644 paragraph, and vice versa.
15645 (try_cursor_movement): Check continued rows, in addition to
15646 continuation rows. Fixes unwarranted scroll when point enters a
15647 continued line of R2L text within an L2R paragraph, or vice versa.
15648 (cursor_row_p): Consider the case of point being equal to
15649 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

15675 * xdisp.c (redisplay_window): When computing centering_position,
15676 account for the height of the header line. (Bug#8874)
15678 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15679 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15680 candidate is selected by the mouse, and that candidate has a
15681 composed character under the mouse.
15683 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15684 coordinates reported by pos-visible-in-window-p for a composed
15685 character in column zero.

15694 consider it a hit if to_charpos is anywhere in the range of the
15695 composed buffer positions.
15697 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15699 * image.c (gif_load): Don't assume that each subimage has the same
15700 dimensions as the base image. Handle disposal method that is
15701 "undefined" by the gif spec (Bug#9335).
15703 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15705 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15711 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15712 from an Org mode buffer to a Speedbar frame.
15714 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15715 a composition, take its buffer position from IT->cmp_it.charpos.
15716 Fixes cursor positioning at the beginning of a line that begins
15717 with a composed character.
15719 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15721 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15722 character bidirectional type, use STRONG_L instead. Fixes crashes
15723 in a buffer produced by `describe-categories'.
15725 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15726 members before the level stack, so they would be saved and
15727 restored when copying iterator state. Fixes incorrect reordering
15728 around TABs covered by display properties.

15865 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15866 properties. (Bug#9284)

16053 * nsfont.m (nsfont_open): Remove assignment to voffset and
16054 unnecessary vars hshink, expand, hd, full_height, min_height.
16055 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16057 * nsterm.h (nsfont_info): Remove voffset field.
16059 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16061 Implement strike-through and overline on NextStep (Bug#8863).
16063 * nsfont.m (nsfont_open): Use underline position provided by font,
16064 instead of hard-coded value of 2.
16065 (nsfont_draw): Call ns_draw_text_decoration instead.
16067 * nsterm.h: Add declaration for ns_draw_text_decoration.
16069 * nsterm.m (ns_draw_text_decoration): New function for drawing
16070 underline, overline, and strike-through.
16071 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16072 ns_draw_text_decoration. Change treatment of cursor drawing to
16073 accommodate underlining, etc.
16075 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16077 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16080 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16082 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16083 Without this fix, if a signal arrives just after memory fills up,
16084 'malloc' might be invoked reentrantly.
16086 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16087 In other words, assume that every image size is allowed, on non-X
16088 hosts. This assumption is probably wrong, but it lets Emacs compile.
16090 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16092 * regex.c (re_iswctype): Convert return values to boolean.
16094 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16096 * xdisp.c (compute_display_string_pos): Don't use cached display
16097 string position if the buffer had its restriction changed.
16100 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16102 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16104 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16106 Integer signedness and overflow and related fixes. (Bug#9079)
16108 * bidi.c: Integer size and overflow fixes.
16109 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16110 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16111 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16112 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16113 (bidi_find_other_level_edge):
16114 Use ptrdiff_t instead of EMACS_INT where either will do.
16115 This works better on 32-bit hosts configured --with-wide-int.
16116 (bidi_cache_ensure_space): Check for size-calculation overflow.
16117 Use % rather than repeated addition, for better worst-case speed.
16118 Don't set bidi_cache_size until after xrealloc returns, because it
16120 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16121 (bidi_cache_ensure_space): Also check that the bidi cache size
16122 does not exceed that of the largest Lisp string or buffer. See Eli
16123 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16125 * alloc.c (__malloc_size_t): Remove.
16126 All uses replaced by size_t. See Andreas Schwab's note
16127 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16129 * image.c: Improve checking for integer overflow.
16130 (check_image_size): Assume that f is nonnull, since
16131 it is always nonnull in practice. This is one less thing to
16132 worry about when checking for integer overflow later.
16133 (x_check_image_size): New function, which checks for integer
16134 overflow issues inside X.
16135 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16136 This removes the need for a memory_full check.
16137 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16138 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16139 (xbm_read_bitmap_data): Change locals back to 'int', since
16140 their values must fit in 'int'.
16141 (xpm_load_image, png_load, tiff_load):
16142 Invoke x_create_x_image_and_pixmap earlier,
16143 to avoid much needless work if the image is too large.
16144 (tiff_load): Treat overly large images as if
16145 x_create_x_image_and_pixmap failed, not as malloc failures.
16146 (gs_load): Use x_check_image_size.
16148 * gtkutil.c: Omit integer casts.
16149 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16150 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16152 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16154 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16155 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16156 would wrongly return t on a 64-bit host.
16158 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16159 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16160 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16161 and therefore cause GCC to emit a bogus diagnostic in some cases.
16163 * image.c: Integer signedness and overflow and related fixes.
16164 This is not an exhaustive set of fixes, but it's time to
16165 record what I've got.
16166 (lookup_pixel_color, check_image_size): Remove redundant decls.
16167 (check_image_size): Don't assume that arbitrary EMACS_INT values
16168 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16169 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16170 (tiff_load, imagemagick_load_image):
16171 Check for overflow in size calculations.
16172 (x_create_x_image_and_pixmap): Remove unnecessary test for
16173 xmalloc returning NULL; that can't happen.
16174 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16175 (xpm_color_bucket): Use better integer hashing function.
16176 (xpm_cache_color): Don't possibly over-allocate memory.
16177 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16178 (gif_memory_source):
16179 Use ptrdiff_t, not int or size_t, to record sizes.
16180 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16181 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16182 either works, as we prefer signed integers.
16183 (tiff_read_from_memory, tiff_write_from_memory):
16184 Return tsize_t, not size_t, since that's what the TIFF API wants.
16185 (tiff_read_from_memory): Don't fail simply because the read would
16186 go past EOF; instead, return a short read.
16187 (tiff_load): Omit no-longer-needed casts.
16188 (Fimagemagick_types): Don't assume size fits into 'int'.
16190 Improve hashing quality when configured --with-wide-int.
16191 * fns.c (hash_string): New function, taken from sxhash_string.
16192 Do not discard information about ASCII character case; this
16193 discarding is no longer needed.
16194 (sxhash-string): Use it. Change sig to match it. Caller changed.
16195 * lisp.h: Declare it.
16196 * lread.c (hash_string): Remove, since we now use fns.c's version.
16197 The fns.c version returns a wider integer if --with-wide-int is
16198 specified, so this should help the quality of the hashing a bit.
16200 * emacs.c: Integer overflow minor fix.
16201 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16202 Define only if GNU_LINUX.
16203 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16205 * dispnew.c: Integer signedness and overflow fixes.
16206 Remove unnecessary forward decls, that were a maintenance hassle.
16207 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16209 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16210 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16211 (prepare_desired_row, line_draw_cost):
16212 Use int, not unsigned, where either works.
16213 (save_current_matrix, restore_current_matrix):
16214 Use ptrdiff_t, not size_t, where either works.
16215 (init_display): Check for overflow more accurately, and without
16216 relying on undefined behavior.
16218 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16219 Remove, replacing with the new symbols in lisp.h. All uses changed.
16220 * fileio.c (make_temp_name):
16221 * filelock.c (lock_file_1, lock_file):
16222 * xdisp.c (message_dolog):
16223 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16224 Use pMd etc. instead.
16225 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16226 replacing the pWIDE etc. symbols removed from editfns.c.
16228 * keyboard.h (num_input_events): Now uintmax_t.
16229 This is (very slightly) less likely to mess up due to wraparound.
16232 * buffer.c: Integer signedness fixes.
16233 (alloc_buffer_text, enlarge_buffer_text):
16234 Use ptrdiff_t rather than size_t when either will do, as we prefer
16237 * alloc.c: Integer signedness and overflow fixes.
16238 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16239 (__malloc_size_t): Default to size_t, not to int.
16240 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16241 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16242 Prefer ptrdiff_t to size_t when either would do, as we prefer
16244 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16245 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16246 Now const. Initialize with values that are in range even if char
16248 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16249 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16250 These functions do the right thing with sizes > 2**32.
16251 (check_depth): Now ptrdiff_t, not int.
16252 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16253 Adjust to new way of storing sizes. Check for size overflow bugs
16255 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16256 slightly wrong anyway, as it missed one instance of
16257 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16258 (refill_memory_reserve): Omit needless cast to size_t.
16259 (mark_object_loop_halt): Mark as externally visible.
16261 * xselect.c: Integer signedness and overflow fixes.
16262 (Fx_register_dnd_atom, x_handle_dnd_message):
16263 Use ptrdiff_t, not size_t, since we prefer signed.
16264 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16265 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16266 x_dnd_atoms_size and x_dnd_atoms_length.
16268 * doprnt.c: Prefer signed to unsigned when either works.
16270 * doprnt.c (doprnt):
16272 * xdisp.c (vmessage):
16273 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16274 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16275 prefer signed arithmetic to avoid comparison confusion.
16276 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16277 but is a bit tricky.
16279 Assume freestanding C89 headers, string.h, stdlib.h.
16280 * data.c, doprnt.c, floatfns.c, print.c:
16281 Include float.h unconditionally.
16282 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16283 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16284 * regex.c: Likewise for stddef.h, string.h.
16285 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16286 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16287 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16288 (STDC_HEADERS): Remove obsolete defines.
16289 * sysdep.c: Include limits.h unconditionally.
16291 Assume support for memcmp, memcpy, memmove, memset.
16292 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16293 * regex.c (memcmp, memcpy):
16294 Remove; we assume C89 now.
16296 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16297 (__malloc_safe_bcopy): Remove; no longer needed.
16299 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16300 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16301 well either way, and we prefer signed to unsigned.
16303 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16305 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16306 closes the connection while we're reading (bug#9182).
16308 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16310 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16311 are specified (Bug#9168).
16313 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16315 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16316 Found by GCC static checking and --with-wide-int on a 32-bit host.
16318 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16320 * xdisp.c (compute_display_string_pos): Fix logic of caching
16321 previous display string position. Initialize cached_prev_pos to
16322 -1. Fixes slow-down at the beginning of a buffer.
16324 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16326 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16327 for attrs[LFACE_FONTSET_INDEX].
16329 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16331 * xml.c (parse_region): Remove unused local
16332 that was recently introduced.
16334 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16336 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16337 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16339 * xdisp.c (move_it_in_display_line_to): Record the best matching
16340 position for TO_CHARPOS while scanning the line, and restore it on
16341 exit if none of the characters scanned was an exact match.
16342 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16343 when exact match is impossible due to invisible text, and the
16344 lines are truncated.
16346 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16348 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16351 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16353 Fix a significant slow-down of cursor motion with C-n, C-p,
16354 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16355 auto-repeat under bidi redisplay in fontified buffers.
16356 * xdisp.c (compute_stop_pos_backwards): New function.
16357 (next_element_from_buffer): Call compute_stop_pos_backwards to
16358 find a suitable prev_stop when we find ourselves before
16360 (reseat): Don't look for prev_stop, as that could mean a very long
16362 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16363 <cached_disp_overlay_modiff>: Cache for last found display string
16365 (compute_display_string_pos): Return the cached position if asked
16366 about the same buffer in the same area of character positions, and
16367 the buffer wasn't changed since the time the display string
16368 position was cached.
16370 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16372 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16373 is an integer, which is important for empty lines. (Bug#9149)
16375 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16377 * frame.c (Fmodify_frame_parameters): In tty case, update the
16378 default face if necessary (Bug#4238).
16380 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16382 * editfns.c (Fstring_to_char): No need to explain what a character
16383 is in the docstring (Bug#6576).
16385 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16387 * xml.c (parse_region): Make sure we always return a tree.
16389 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16391 * xml.c (parse_region): If a document contains only comments,
16394 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16396 * xml.c (make_dom): Return comments, too.
16398 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16401 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16402 and the surrounding thread.
16403 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16404 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16405 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16407 * s/openbsd.h (BROKEN_SIGIO): Define.
16408 * unexelf.c (unexec) [__OpenBSD__]:
16409 Don't update the .mdebug section of the Alpha COFF symbol table.
16411 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16413 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16416 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16418 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16419 This fixes some race conditions on the permissions of any newly
16422 * alloc.c (valid_pointer_p): Use pipe, not open.
16423 This fixes some permissions issues when debugging.
16425 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16426 If fchown fails to set both uid and gid, try to set just gid,
16427 as that is sometimes allowed. Adjust the file's mode to eliminate
16428 setuid or setgid bits that are inappropriate if fchown fails.
16430 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16432 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16433 to compare Lisp_Objects.
16434 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16435 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16436 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16438 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16440 * lread.c (read_integer): Unread even EOF character.
16441 (read1): Likewise. Properly record start position of symbol.
16443 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16444 symbol character follows.
16446 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16448 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16449 This works around a problem with the previous change to Fcopy_file.
16450 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16451 and without this change, GCC might complain about discarding
16452 fchown's return value.
16454 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16456 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16458 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16460 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16462 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16464 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16465 it's used from the C level.
16467 * process.c: Use the same condition for POLL_FOR_INPUT in both
16468 keyboard.c and process.c (bug#1858).
16470 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16472 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16473 (Fgnutls_boot): Use it.
16475 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16477 * doc.c (Fsubstitute_command_keys): Revert last change.
16479 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16481 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16482 quotes the next character, and doesn't affect other longer
16483 sequences (bug#8935).
16485 * lread.c (syms_of_lread): Clarify that is isn't only
16486 `eval-buffer' and `eval-defun' that's affected by
16487 `lexical-binding' (bug#8460).
16489 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16491 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16492 bidi redisplay when a line includes both an image and is truncated.
16494 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16496 Fix minor problems found by static checking.
16497 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16498 (elsz): Now a signed constant, not a size_t var. We prefer signed
16499 types to unsigned, to avoid integer comparison confusion. Without
16500 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16501 "cannot optimize loop, the loop counter may overflow", a symptom
16503 * indent.c (Fvertical_motion): Mark locals as initialized.
16504 * xdisp.c (reseat_to_string): Fix pointer signedness issue.

16529 buffer position was specified. Initialize paragraph_embedding to
16531 (reseat_to_string): Initialize the bidi iterator.
16532 (display_string): If we need to ignore text properties of
16533 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16534 original value of -1 will not work with bidi.)

16547 base_level_stop; instead, set base_level_stop to BEGV.
16548 Fixes crashes in vertical-motion.
16549 (next_element_from_buffer): Improve commentary for when
16550 the iterator is before prev_stop.
16551 (init_iterator): Initialize bidi_p from the default value of
16552 bidi-display-reordering, not from buffer-local value. Use the
16553 buffer-local value only if initializing for buffer iteration.

16577 (display_menu_bar): Force left-to-right direction. Add a FIXME
16578 comment for making that be controlled by a user option.

16592 pushed the iterator stack, restore the internal state of the bidi
16593 iterator by calling bidi_pop_it same number of times.
16594 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16595 and we are bidi-iterating, don't decrement the iterator position;
16596 instead, set the first_elt flag in the bidi iterator, to produce
16598 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16599 (push_display_prop): xassert that we are iterating a buffer.

16603 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16604 correctly. Don't assume unibyte strings are not bidi-reordered.

16612 popping after iteration over a string that came from a display
16613 property. Fix a typo in popping stretch info. Add an assertion
16614 for verifying that the iterator position is in sync with the bidi
16616 (handle_single_display_spec, get_overlay_strings_1)

17032 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

17069 Random fixes. E.g., (random) never returned negative values.
17070 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17071 subseconds part to the entropy, as that's a bit more random.
17072 Prefer signed to unsigned, since the signedness doesn't matter and
17073 in general we prefer signed. When given a limit, use a
17074 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17075 latter isn't right if USE_2_TAGS_FOR_INTS.
17076 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17077 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17094 * buffer.c (Foverlay_put): Say what the return value is
17097 * fileio.c (barf_or_query_if_file_exists): Check first if the file

17101 error be more correct.
17103 * fns.c (Frequire): Remove the mention of the .gz files, since

17117 Qgnutls_bootprop_verify_error (which is no longer used).
17119 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17120 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17121 Also (re)move comments that are misplaced or no longer relevant.

17222 * eval.c (struct backtrace): Simplify and port the data structure.
17223 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17224 signed bit field, as this assumption is not portable and it makes
17225 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17226 "char debug_on_exit : 1" as this is not portable either; instead,
17227 use the portable "unsigned int debug_on_exit : 1". Remove unused
17228 member evalargs. Remove obsolete comments about cc bombing out.
17230 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17388 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
17390 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
17392 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
17394 Integer and buffer overflow fixes (Bug#8873).
17396 * print.c (printchar, strout): Check for string overflow.
17397 (PRINTPREPARE, printchar, strout):
17398 Don't set size unless allocation succeeds.
17400 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17401 for sizes. Check for string overflow more accurately.
17402 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17404 * macros.c: Integer and buffer overflow fixes.
17405 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17406 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
17407 Use ptrdiff_t, not int, for sizes.
17408 Don't increment bufsize until after realloc succeeds.
17409 Check for size-calculation overflow.
17410 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17412 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17414 * lread.c: Integer overflow fixes.
17415 (read_integer): Radix is now EMACS_INT, not int,
17416 to improve quality of diagnostics for out-of-range radices.
17417 Calculate buffer size correctly for out-of-range radices.
17418 (read1): Check for integer overflow in radices, and in
17419 read-circle numbers.
17420 (read_escape): Avoid int overflow.
17421 (Fload, openp, read_buffer_size, read1)
17422 (substitute_object_recurse, read_vector, read_list, map_obarray):
17423 Use ptrdiff_t, not int, for sizes.
17424 (read1): Use EMACS_INT, not int, for sizes.
17425 Check for size overflow.
17427 * image.c (cache_image): Check for size arithmetic overflow.
17429 * lread.c: Integer overflow issues.
17430 (saved_doc_string_size, saved_doc_string_length)
17431 (prev_saved_doc_string_size, prev_saved_doc_string_length):
17432 Now ptrdiff_t, not int.

17434 out-of-range doc string lengths.
17435 (read_list): Don't assume file position fits in int.
17436 (read_escape): Check for hex character overflow.
17438 2011-06-22 Leo Liu <sdl.web@gmail.com>
17440 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17441 Move to minibuffer.el.
17443 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17445 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17446 The following patches are for when GLYPH_DEBUG && !XASSERT.
17447 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17448 * dispnew.c (flush_stdout):
17449 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17450 Mark as externally visible.
17451 * dispnew.c (check_window_matrix_pointers): Now static.
17452 * dispnew.c (window_to_frame_vpos):
17453 * xfns.c (unwind_create_frame):
17454 * xterm.c (x_check_font): Remove unused local.
17455 * scroll.c (CHECK_BOUNDS):
17456 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17457 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17458 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17459 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17460 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17462 (debug_method_add): Use va_list and vsprintf rather than relying
17463 on undefined behavior with wrong number of arguments.
17464 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17465 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17466 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17467 since we're not interested in debugging glyphs with old libraries.
17468 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17469 GCC 4.6.0's static checking.
17471 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17473 Integer overflow and signedness fixes (Bug#8873).
17474 A few related buffer overrun fixes, too.

17482 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17483 (x_create_bitmap_from_xpm_data):
17484 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17485 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17487 * xfaces.c (load_pixmap):
17488 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17489 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17490 (.bitmaps_last, struct x_output.icon_bitmap):
17491 Use ptrdiff_t, not int, for bitmap indexes.
17492 (x_allocate_bitmap_record): Check for size overflow.
17493 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17495 Use ptrdiff_t, not int, for overlay counts.
17496 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17497 * editfns.c (overlays_around, get_pos_property):
17498 * textprop.c (get_char_property_and_overlay):
17499 * xdisp.c (next_overlay_change, note_mouse_highlight):
17500 * xfaces.c (face_at_buffer_position):
17501 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17502 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17503 (Fnext_overlay_change, Fprevious_overlay_change)
17504 (mouse_face_overlay_overlaps, Foverlays_in):
17505 Use ptrdiff_t, not int, for sizes.
17506 (overlays_at, overlays_in): Check for size-calculation overflow.
17508 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17510 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17511 (x_session_initialize): Do not assume string length fits in int.
17513 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17514 This is unlikely, but can occur if DPI is outlandish.
17516 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17517 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17519 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17520 * xrdb.c (magic_file_p, search_magic_path):
17521 Omit last arg SUFFIX; it was always 0. All callers changed.
17522 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17524 * xfont.c (xfont_match): Avoid need for strlen.
17526 * xfns.c: Don't assume strlen fits in int.
17527 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17529 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17530 not unsigned long, as we prefer signed integers. All callers changed.
17531 Detect integer overflow in repeat count.
17532 (message_dolog): Don't assume print length fits in 39 bytes.
17533 (display_mode_element): Don't assume strlen fits in int.
17535 * termcap.c: Don't assume sizes fit in int and never overflow.
17536 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17537 (gobble_line): Check for size-calculation overflow.
17539 * minibuf.c (Fread_buffer):
17540 * lread.c (intern, intern_c_string):
17541 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17542 Don't assume string length fits in int.
17544 * keyboard.c (parse_tool_bar_item):
17545 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17547 * font.c: Don't assume string length fits in int.
17548 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17549 Use ptrdiff_t, not int.
17550 (font_intern_prop): Don't assume string length fits in int.
17551 Don't assume integer property fits in fixnum.
17552 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17554 * filelock.c: Fix some buffer overrun and integer overflow issues.
17555 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17556 Reformulate so as not to need the command string.
17557 Invoke gzip -cd rather than gunzip, as it's more portable.
17558 (lock_info_type, lock_file_1, lock_file):
17559 Don't assume pid_t and time_t fit in unsigned long.
17560 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17561 (current_lock_owner): Prefer signed type for sizes.
17562 Use memcpy, not strncpy, where memcpy is what is really wanted.
17563 Don't assume (via atoi) that time_t and pid_t fit in int.
17564 Check for time_t and/or pid_t out of range, e.g., via a network share.
17565 Don't alloca where an auto var works fine.
17567 * fileio.c: Fix some integer overflow issues.
17568 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17569 Don't assume string length fits in int.
17570 (directory_file_name): Don't assume string length fits in long.
17571 (make_temp_name): Don't assume pid fits in int, or that its print
17572 length is less than 20.
17574 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17576 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17578 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17580 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17581 We prefer signed integers, even for size calculations.
17583 * emacs.c: Don't assume string length fits in 'int'.
17584 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17585 (main): Don't invoke strlen when not needed.
17587 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17588 (XD_DEBUG_MESSAGE): Don't waste a byte.
17590 * callproc.c (getenv_internal_1, getenv_internal)
17591 (Fgetenv_internal):
17592 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17594 * lread.c (invalid_syntax): Omit length argument.
17595 All uses changed. This doesn't fix a bug, but it simplifies the
17596 code away from its former Hollerith-constant appearance, and it's
17597 one less 'int' to worry about when looking at integer-overflow issues.
17598 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17600 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17601 This didn't break anything, but it didn't help either.
17602 It's confusing to put a bogus integer in a place where the actual
17603 value does not matter.
17604 (LIST_END_P): Remove unused macro and its bogus comment.
17605 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17607 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17608 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17610 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17611 We prefer signed types, and the value cannot exceed the EMACS_INT
17612 range anyway (because otherwise the length would not be representable).
17613 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17614 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17615 This avoids a GCC warning when WIDE_EMACS_INT.
17617 * indent.c (sane_tab_width): New function.
17618 (current_column, scan_for_column, Findent_to, position_indentation)
17619 (compute_motion): Use it. This is just for clarity.
17620 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17622 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17624 * lisp.h (lint_assume): New macro.
17625 * composite.c (composition_gstring_put_cache):
17626 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17628 * editfns.c, insdel.c:
17629 Omit unnecessary forward decls, to simplify future changes.
17631 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17633 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17635 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17636 Use much-faster test for byte-length change.
17637 Don't assume string byte-length fits in 'int'.
17638 Check that character arg fits in 'int'.
17639 (mapcar1): Declare byte as byte, for clarity.
17641 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17643 * fns.c (concat): Catch string overflow earlier.
17644 Do not rely on integer wraparound.
17646 * dispextern.h (struct it.overlay_strings_charpos)
17647 (struct it.selective): Now EMACS_INT, not int.
17648 * xdisp.c (forward_to_next_line_start)
17649 (back_to_previous_visible_line_start)
17650 (reseat_at_next_visible_line_start, next_element_from_buffer):
17651 Don't arbitrarily truncate the value of 'selective' to int.
17653 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17655 * composite.c: Don't truncate sizes to 'int'.
17656 (composition_gstring_p, composition_reseat_it)
17657 (composition_adjust_point): Use EMACS_INT, not int.
17658 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17659 not EMACS_UINT, for indexes.
17661 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17663 * buffer.c: Include <verify.h>.
17664 (struct sortvec.priority, struct sortstr.priority):
17665 Now EMACS_INT, not int.
17666 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17667 (struct sortstr.size, record_overlay_string)
17668 (struct sortstrlist.size, struct sortlist.used):
17669 Don't truncate size to int.
17670 (record_overlay_string): Check for size-calculation overflow.
17671 (init_buffer_once): Check at compile-time, not run-time.
17673 2011-06-22 Jim Meyering <meyering@redhat.com>
17675 Don't leak an XBM-image-sized buffer
17676 * image.c (xbm_load): Free the image buffer after using it.
17678 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17681 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17682 that Sun C diagnosed.
17683 * fns.c (secure_hash): Fix pointer signedness issue.
17684 * intervals.c (static_offset_intervals): New function.
17685 (offset_intervals): Use it.
17687 2011-06-21 Leo Liu <sdl.web@gmail.com>
17690 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17693 * fns.c (secure_hash): Rename from crypto_hash_function and change
17694 the first arg to accept symbols.
17695 (Fsecure_hash): New primitive.
17696 (syms_of_fns): New symbols.
17698 2011-06-20 Deniz Dogan <deniz@dogan.se>
17700 * process.c (Fset_process_buffer): Clarify return value in
17703 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17705 * dispnew.c (add_window_display_history): Use BVAR.
17707 * xdisp.c (debug_method_add): Use BVAR.
17708 (check_window_end, dump_glyph_matrix, dump_glyph)
17709 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17711 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17714 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17715 check till after the cache is created in init_frame_faces.
17717 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17719 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17721 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17723 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17724 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17725 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17727 Improve buffer-overflow checking (Bug#8873).
17728 * fileio.c (Finsert_file_contents):
17729 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17730 Remove the old (too-loose) buffer overflow checks.
17731 They weren't needed, since make_gap checks for buffer overflow.
17732 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17733 The old code merely checked for Emacs fixnum overflow, and relied
17734 on undefined (wraparound) behavior. The new code avoids undefined
17735 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17737 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17738 Tune. Don't use wider integers than needed. Don't use alloca.
17739 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17741 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17743 * insdel.c, lisp.h (buffer_overflow): New function.
17744 (insert_from_buffer_1, replace_range, replace_range_2):
17745 * insdel.c (make_gap_larger):
17746 * editfns.c (Finsert_char):
17747 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17749 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17751 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17753 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17755 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17756 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17758 * fileio.c: Don't assume EMACS_INT fits in off_t.
17759 (emacs_lseek): New static function.
17760 (Finsert_file_contents, Fwrite_region): Use it.
17761 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17763 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17765 * fns.c: Don't overflow int when computing a list length.
17766 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17767 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17768 truncation on 64-bit hosts. Check for QUIT every
17769 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17770 faster and is responsive enough.
17771 (Flength): Report an error instead of overflowing an integer.
17772 (Fsafe_length): Return a float if the value is not representable
17773 as a fixnum. This shouldn't happen except in contrived situations.
17774 (Fnthcdr, Fsort): Don't assume list length fits in int.
17775 (Fcopy_sequence): Don't assume vector length fits in int.
17777 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17778 (header_size, word_size): New constants.
17779 (allocate_vectorlike): Don't check size overflow here.
17780 (allocate_vector): Check it here instead, since this is the only
17781 caller of allocate_vectorlike that could cause overflow.
17782 Check that the new vector's length is representable as a fixnum.
17784 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17785 The previous code was bogus. For example, next_almost_prime (32)
17786 returned 39, which is undesirable as it is a multiple of 3; and
17787 next_almost_prime (24) returned 25, which is a multiple of 5 so
17788 why was the code bothering to check for multiples of 7?
17790 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17792 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17794 Variadic C functions now count arguments with ptrdiff_t.
17795 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17796 Back then I didn't know that the Emacs coding style prefers signed int.
17797 Also, in the meantime I found a few more instances where arguments
17798 were being counted with int, which may truncate counts on 64-bit
17799 machines, or EMACS_INT, which may be unnecessarily wide.
17800 * lisp.h (struct Lisp_Subr.function.aMANY)
17801 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17802 Arg counts are now ptrdiff_t, not size_t.
17803 All variadic functions and their callers changed accordingly.
17804 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17805 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17806 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17807 * callint.c (Fcall_interactively): Check arg count for overflow,
17808 to avoid potential buffer overrun. Use signed char, not 'int',
17809 for 'varies' array, so that we needn't bother to check its size
17810 calculation for overflow.
17811 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17812 * eval.c (apply_lambda):
17813 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17814 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17815 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17817 * callint.c (Fcall_interactively): Don't use index var as event count.
17819 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17820 * mem-limits.h (SIZE): Remove; no longer used.
17822 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17824 Remove unnecessary casts.
17825 * xterm.c (x_term_init):
17826 * xfns.c (x_set_border_pixel):
17827 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17828 These aren't needed now that we assume ANSI C.
17830 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17831 It's more likely to cause problems (due to unsigned overflow)
17834 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17836 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17838 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17840 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17842 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17844 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17846 GLYPH_CODE_FACE returns EMACS_INT, not int.
17847 * dispextern.h (merge_faces):
17848 * xfaces.c (merge_faces):
17849 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17850 Don't assume EMACS_INT fits in int.
17852 * character.h (CHAR_VALID_P): Remove unused parameter.
17853 * fontset.c, lisp.h, xdisp.c: All uses changed.
17855 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17857 * fns.c (concat): Minor tuning based on overflow analysis.
17858 This doesn't fix any bugs. Use int to hold character, instead
17859 of constantly refetching from Emacs object. Use XFASTINT, not
17860 XINT, for value known to be a character. Don't bother comparing
17861 a single byte to 0400, as it's always less.
17863 * floatfns.c (Fexpt):
17864 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17866 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17869 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17871 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17872 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17873 incorrectly succeed when S was a string, because 4294967386 was
17874 truncated before it was used.
17876 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17877 Otherwise, an out-of-range integer could cause undefined behavior
17880 * composite.c: Use int, not EMACS_INT, for characters.
17881 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17882 EMACS_INT, for values that are known to be in character range.
17883 This doesn't fix any bugs but is the usual style inside Emacs and
17884 may generate better code on 32-bit machines.
17886 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17887 This is for reasons similar to the recent CHAR_STRING fix.
17888 * charset.c (Fencode_char): Check that character arg is actually
17889 a character. Pass an int to ENCODE_CHAR.
17890 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17891 wider than 'int', as a compile-time check to prevent future regressions
17894 * character.c (char_string): Remove unnecessary casts.
17896 Make sure a 64-bit char is never passed to CHAR_STRING.
17897 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17898 by silently ignoring the top 32 bits, allowing some values
17899 that were far too large to be valid characters.
17900 * character.h: Include <verify.h>.
17901 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17902 arguments are no wider than unsigned, as a compile-time check
17903 to prevent future regressions in this area.
17905 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17906 (Fsubst_char_in_region):
17908 * xdisp.c (decode_mode_spec_coding):
17909 Adjust to CHAR_STRING's new requirement.
17910 * editfns.c (Finsert_char, Fsubst_char_in_region):
17911 * fns.c (concat): Check that character args are actually
17912 characters. Without this test, these functions did the wrong
17913 thing with wildly out-of-range values on 64-bit hosts.
17915 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17916 These casts should not be needed on 32-bit hosts, either.
17917 * keyboard.c (read_char):
17918 * lread.c (Fload): Remove casts to unsigned.
17920 * lisp.h (UNSIGNED_CMP): New macro.
17921 This fixes comparison bugs on 64-bit hosts.
17922 (ASCII_CHAR_P): Use it.
17923 * casefiddle.c (casify_object):
17924 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17925 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17926 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17927 * dispextern.h (FACE_FROM_ID):
17928 * keyboard.c (read_char): Use UNSIGNED_CMP.
17930 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17931 not to EMACS_INT, to avoid GCC warning.
17933 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17935 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17936 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17937 isn't needed on 32-bit machines.
17939 * buffer.c (Fgenerate_new_buffer_name):
17940 Use EMACS_INT for count, not int.
17941 (advance_to_char_boundary): Return EMACS_INT, not int.
17943 * data.c (Qcompiled_function): Now static.
17945 * window.c (window_body_lines): Now static.
17947 * image.c (gif_load): Rename local to avoid shadowing.
17949 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17950 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17951 * alloc.c (make_save_value): Integer argument is now of type
17952 ptrdiff_t, not int.
17953 (mark_object): Use ptrdiff_t, not int.
17954 * lisp.h (pD): New macro.
17955 * print.c (print_object): Use it.
17957 * alloc.c: Use EMACS_INT, not int, to count objects.
17958 (total_conses, total_markers, total_symbols, total_vector_size)
17959 (total_free_conses, total_free_markers, total_free_symbols)
17960 (total_free_floats, total_floats, total_free_intervals)
17961 (total_intervals, total_strings, total_free_strings):
17962 Now EMACS_INT, not int. All uses changed.
17963 (Fgarbage_collect): Compute overall total using a double, so that
17964 integer overflow is less likely to be a problem. Check for overflow
17965 when converting back to an integer.
17966 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17967 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17968 These were 'int' variables that could overflow on 64-bit hosts;
17969 they were never used, so remove them instead of repairing them.
17970 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17971 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17972 Previously, this ceilinged at INT_MAX, but that doesn't work on
17974 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17976 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17977 (allocate_vectorlike): Check for ptrdiff_t overflow.
17978 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17979 when a (possibly-narrower) signed value would do just as well.
17980 We prefer using signed arithmetic, to avoid comparison confusion.
17982 * alloc.c: Catch some string size overflows that we were missing.
17983 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17984 for convenience in STRING_BYTES_MAX.
17985 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17986 The definition here is exact; the one in lisp.h was approximate.
17987 (allocate_string_data): Check for string overflow. This catches
17988 some instances we weren't catching before. Also, it catches
17989 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17990 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17991 and ptrdiff_t and EMACS_INT are both 64 bits.
17993 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17994 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17995 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17997 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17999 * alloc.c (Fmake_string): Check for out-of-range init.
18001 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18003 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18005 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18007 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18008 xg_get_default_scrollbar_width.

18011 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18012 (style_changed_cb): Call update_theme_scrollbar_width and call

18018 and height if HAVE_GTK3 (Bug#8505).
18019 (scroll_bar_width_for_theme): New variable.
18020 (update_theme_scrollbar_width): New function.
18021 (xg_get_default_scrollbar_width): Move code to
18022 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18023 (xg_initialize): Call update_theme_scrollbar_width.
18025 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18027 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18029 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18031 * frame.c (make_frame): Call other_buffer_safely instead of
18034 * window.c (temp_output_buffer_show): Call display_buffer with
18035 second argument Vtemp_buffer_show_specifiers and reset latter
18036 immediately after the call.
18037 (Vtemp_buffer_show_specifiers): New variable.
18038 (auto_window_vscroll_p, next_screen_context_lines)
18039 (Vscroll_preserve_screen_position): Remove leading asterisks from

18060 * widgetprv.h (emacsFrameClassRec): Remove decl.
18061 * window.c (delete_deletable_window): Now returns void, since it
18062 wasn't returning anything.
18063 (compare_window_configurations): Remove unused locals.
18064 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

18080 (syms_of_image): Use DEFSYM. New symbol `delay'.
18082 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18084 * window.c (delete_deletable_window): Re-add.
18085 (Fset_window_configuration): Rewrite to handle dead buffers and
18086 consequently deletable windows.
18087 (window_tree, Fwindow_tree): Remove. Supply functionality in
18089 (compare_window_configurations): Simplify code.

18217 2011-06-10 Martin Rudalics <rudalics@gmx.at>
18219 * window.c: Remove declarations of Qwindow_size_fixed,
18220 window_min_size_1, window_min_size_2, window_min_size,
18221 size_window, window_fixed_size_p, enlarge_window, delete_window.
18222 Remove static from declaration of Qdelete_window, it's
18223 temporarily needed by Fbury_buffer.
18224 (replace_window): Don't assign orig_top_line and
18226 (Fdelete_window, delete_window): Remove. Window deletion is

18228 (window_loop): Remove DELETE_OTHER_WINDOWS case.
18229 Replace Fdelete_window calls with calls to Qdelete_window.
18230 (Fdelete_other_windows): Remove. Deleting other windows is

18603 value of a `display' property is a "replacing spec".
18604 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18605 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18635 * gnutls.c: Use Emacs's memory allocators.
18636 Without this change, the gnutls library would invoke malloc etc.
18637 directly, which causes problems on non-SYNC_INPUT hosts, and which
18638 runs afoul of improving memory_full behavior. (Bug#8761)
18639 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18640 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18641 xfree instead of the default malloc, realloc, free.
18642 (Fgnutls_boot): No need to check for memory allocation failure,
18643 since xmalloc does that for us.

18672 need to be updated by these changes.
18673 * fns.c (make_hash_table, maybe_resize_hash_table):
18674 Check for integer overflow with large hash tables.
18675 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18676 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18677 (SXHASH_REDUCE): New macro.
18678 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18679 Use it instead of discarding useful hash info with large hash values.
18680 (sxhash_float): New function.
18681 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18682 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18683 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18684 Rewrite to use FIXNUM_BITS, as this simplifies things.
18685 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18686 Adjust signatures to match updated version of code.
18687 (consing_since_gc): Now EMACS_INT, since a single hash table can
18688 use more than INT_MAX bytes.
18690 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18692 Make it possible to build with GCC-4.6+ -O2 -flto.
18694 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18696 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18698 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18699 Call minibuffer-inactive-mode.
18701 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18703 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18704 Update dependencies.
18706 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18708 * data.c (init_data): Remove code for UTS, this system is not
18711 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18713 Don't force ./temacs to start in terminal mode.
18715 * frame.c (make_initial_frame): Initialize faces in all cases, not
18716 only when CANNOT_DUMP is defined.
18717 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18719 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18721 * dispnew.c (add_window_display_history): Use const for the string
18722 pointer. Remove declaration, not needed.
18724 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18726 Use 'inline', not 'INLINE'.
18727 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18728 * alloc.c, fontset.c (INLINE): Remove.
18729 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18730 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18731 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18732 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18733 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18735 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18737 Make it possible to run ./temacs.
18739 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18740 syms_of_callproc does the same thing. Remove test for
18741 "initialized", do it in the caller.
18742 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18744 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18746 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18747 (read_minibuf): Use get_minibuffer.
18748 (syms_of_minibuf): Use DEFSYM.
18749 (Qmetadata): New var.
18750 * data.c (Qbuffer): Don't make it static.
18751 (syms_of_data): Use DEFSYM.
18753 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18755 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18756 (CCL_CODE_MIN): New macro.
18758 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18760 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18762 * eval.c (Qdebug): Now static.
18763 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18764 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18765 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18767 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18769 * image.c: Various fixes to ImageMagick code comments.
18770 (Fimagemagick_types): Doc fix.
18772 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18774 Minor fixes prompted by GCC 4.6.0 warnings.
18776 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18778 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18779 (x_clipboard_manager_save_all): Move extern decl to ...
18780 * xterm.h: ... here, so that it can be checked for consistency.
18782 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18784 * xselect.c (x_clipboard_manager_save_frame)
18785 (x_clipboard_manager_save_all): New functions.
18786 (Fx_clipboard_manager_save): Lisp function deleted.
18788 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18789 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18791 * xterm.h: Update prototype.
18793 2011-05-28 William Xu <william.xwl@gmail.com>
18795 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18796 exiting (Bug#8239).
18798 2011-05-28 Jim Meyering <meyering@redhat.com>
18800 Avoid a sign-extension bug in crypto_hash_function.
18801 * fns.c (to_uchar): Define.
18802 (crypto_hash_function): Use it to convert some newly-signed
18803 variables to unsigned, to avoid sign-extension bugs. For example,
18804 without this change, (md5 "truc") would evaluate to
18805 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18806 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18807 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18809 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18811 Integer overflow fixes.
18813 * dbusbind.c: Serial number integer overflow fixes.
18814 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18815 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18816 to hold a serial number that is too large for a fixnum.
18817 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18818 Check for serial numbers out of range. Decode any serial number
18819 that was so large that it became a float. (Bug#8722)
18821 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18822 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18823 Use XFASTINT rather than XUINT when numbers are nonnegative.
18824 (xd_append_arg, Fdbus_method_return_internal):
18825 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18826 arguments, check that Lisp number is nonnegative, rather than
18827 silently wrapping negative numbers around. (Bug#8722)
18828 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18831 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18833 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18835 ccl: Add integer overflow checks.
18836 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18837 (IN_INT_RANGE): New macros.
18838 (ccl_driver): Use them to check for integer overflow when
18839 decoding a CCL program. Many of the new checks are whether XINT (x)
18840 fits in int; it doesn't always, on 64-bit hosts. The new version
18841 doesn't catch all possible integer overflows, but it's an
18842 improvement. (Bug#8719)
18844 * alloc.c (make_event_array): Use XINT, not XUINT.
18845 There's no need for unsigned here.
18847 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18848 This follows up to the 2011-05-06 change that substituted uintptr_t
18849 for EMACS_INT. This case wasn't caught back then.
18851 Rework Fformat to avoid integer overflow issues.
18852 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18853 now (part of C89). Include <verify.h>.
18854 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18855 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18856 (Fformat): Avoid the prepass trying to compute sizes; it was only
18857 approximate and thus did not catch overflow reliably. Instead, walk
18858 through the format just once, formatting and computing sizes as we go,
18859 checking for integer overflow at every step, and allocating a larger
18860 buffer as needed. Keep track separately whether the format is
18861 multibyte. Keep only the most-recently calculated precision, rather
18862 than them all. Record whether each argument has been converted to
18863 string. Use EMACS_INT, not int, for byte and char and arg counts.
18864 Support field widths and precisions larger than INT_MAX. Avoid
18865 sprintf's undefined behavior with conversion specifications such as %#d
18866 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18867 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18868 formatting out-of-range floating point numbers with int
18869 formats. (Bug#8668)
18871 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18873 * data.c: Avoid integer truncation in expressions involving floats.
18874 * data.c: Include <intprops.h>.
18875 (arith_driver): When there's an integer overflow in an expression
18876 involving floating point, convert the integers to floating point
18877 so that the resulting value does not suffer from catastrophic
18878 integer truncation. For example, on a 64-bit host (* 4
18879 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18880 Do not rely on undefined behavior after integer overflow.
18882 merge count_size_as_multibyte, parse_str_to_multibyte
18883 * character.c, character.h (count_size_as_multibyte):
18884 Rename from parse_str_to_multibyte; all uses changed.
18885 Check for integer overflow.
18886 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18887 since it's now a duplicate of the other. This is more of
18888 a character than a buffer op, so better that it's in character.c.
18889 * fns.c, print.c: Adjust to above changes.
18891 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18893 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18895 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18897 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18898 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18899 (x_clipboard_manager_save): Now static.
18900 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18902 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18903 (crypto_hash_function): Now static.
18904 Fix pointer signedness problems. Avoid unnecessary initializations.
18906 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18908 * termhooks.h (Vselection_alist): Make it terminal-local.
18910 * terminal.c (create_terminal): Initialize it.
18912 * xselect.c: Support for clipboard managers.
18913 (Vselection_alist): Move to termhooks.h as terminal-local var.
18914 (LOCAL_SELECTION): New macro.
18915 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18916 (symbol_to_x_atom): Remove gratuitous arg.
18917 (x_handle_selection_request, lisp_data_to_selection_data)
18918 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18919 (x_own_selection, x_get_local_selection, x_convert_selection):
18920 New arg, specifying work frame. Use terminal-local Vselection_alist.
18921 (some_frame_on_display): Delete unused function.
18922 (Fx_own_selection_internal, Fx_get_selection_internal)
18923 (Fx_disown_selection_internal, Fx_selection_owner_p)
18924 (Fx_selection_exists_p): New optional frame arg.
18925 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18926 (x_handle_selection_clear): Don't treat other terminals with the
18927 same keyboard specially. Use the terminal-local Vselection_alist.
18928 (x_clear_frame_selections): Use Frun_hook_with_args.
18930 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18932 * xterm.h: Add support for those atoms.
18934 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18936 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18937 (converted_selections, conversion_fail_tag): New global variables.
18938 (x_selection_request_lisp_error): Free the above.
18939 (x_get_local_selection): Remove unnecessary code.
18940 (x_reply_selection_request): Args changed; handle arbitrary array
18941 of converted selections stored in converted_selections.
18942 Separate the XChangeProperty and SelectionNotify steps.
18943 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18944 (x_convert_selection): New function.
18945 (x_handle_selection_event): Simplify.
18946 (x_get_foreign_selection): Don't ignore incoming requests while
18947 waiting for an answer; this will fail when we implement
18948 SAVE_TARGETS, and seems unnecessary anyway.
18949 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18950 (Vx_sent_selection_functions): Doc fix.
18952 2011-05-26 Leo Liu <sdl.web@gmail.com>
18954 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18956 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18958 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18960 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18961 for fringe update if it has periodic bitmap.
18962 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18963 and fringe_bitmap_periodic_p.
18965 * fringe.c (get_fringe_bitmap_data): New function.
18966 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18967 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18968 row. Mark glyph row for fringe update if periodicity changed.
18970 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18971 for fringe update unless it has periodic bitmap.
18973 2011-05-25 Kenichi Handa <handa@m17n.org>
18975 * xdisp.c (get_next_display_element): Set correct it->face_id for
18976 a static composition.
18978 2011-05-24 Leo Liu <sdl.web@gmail.com>
18981 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18983 * fns.c (crypto_hash_function, Fsha1): New function.
18984 (Fmd5): Use crypto_hash_function.
18985 (syms_of_fns): Add Ssha1.
18987 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18989 * gnutls.c: Remove unused macros.
18990 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18991 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18992 Remove macros that are defined and never used.
18993 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18995 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18997 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18998 (Fx_get_selection_internal): Minor cleanup.
18999 (Fx_own_selection_internal): Rename arguments for consistency with
19002 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19004 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19006 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19008 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19010 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19012 * dispnew.c (scrolling_window): Don't exclude the case that the
19013 last enabled row in the desired matrix touches the bottom boundary.
19015 2011-05-21 Glenn Morris <rgm@gnu.org>
19017 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19018 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19019 and add some more files.
19021 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19023 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19024 report_file_error introduced by the change from 2011-05-07.
19026 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19028 * systime.h (Time): Define only if emacs is defined.
19029 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19030 where the include path doesn't have X11/X.h by default. See
19031 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19033 2011-05-20 Kenichi Handa <handa@m17n.org>
19035 * composite.c (find_automatic_composition): Fix previous change.
19037 2011-05-20 Glenn Morris <rgm@gnu.org>
19039 * lisp.mk: New file, split from Makefile.in.
19040 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19041 (shortlisp): Remove.
19042 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19044 2011-05-19 Glenn Morris <rgm@gnu.org>
19046 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19047 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19048 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19049 (lisp): Set the order to that of loadup.el.
19050 (shortlisp): Make it a copy of $lisp.
19051 (SOME_MACHINE_LISP): Remove.
19052 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19053 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19055 2011-05-18 Kenichi Handa <handa@m17n.org>
19057 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19058 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19059 (find_automatic_composition): Mostly rewrite for efficiency.
19061 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19063 * makefile.w32-in: Update dependencies.
19065 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19067 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19068 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19070 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19072 Fix some integer overflow issues, such as string length overflow.
19074 * insdel.c (count_size_as_multibyte): Check for string overflow.
19076 * character.c (lisp_string_width): Check for string overflow.
19077 Use EMACS_INT, not int, for string indexes and lengths; in
19078 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19079 the resulting string length overflows an EMACS_INT; instead,
19080 report a string overflow if no precision given. When checking for
19081 precision exhaustion, use a check that cannot possibly have
19082 integer overflow. (Bug#8675)
19083 * character.h (lisp_string_width): Adjust to new signature.
19085 * alloc.c (string_overflow): New function.
19086 (Fmake_string): Use it. This doesn't change behavior, but saves
19087 a few bytes and will simplify future changes.
19088 * character.c (string_escape_byte8): Likewise.
19089 * lisp.h (string_overflow): New decl.
19091 Fixups, following up to the user-interface timestamp change.
19092 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19093 for UI timestamps, instead of unsigned long.
19094 * msdos.c (mouse_get_pos): Likewise.
19095 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19096 * w32gui.h (Time): Define by including "systime.h" rather than by
19097 declaring it ourselves. (Bug#8664)
19099 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19100 * image.c (clear_image_cache): Likewise.
19102 * term.c (term_mouse_position): Don't assume time_t wraparound.
19104 Be more systematic about user-interface timestamps.
19105 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19106 and sometimes 'EMACS_UINT', to represent these timestamps.
19107 This change causes it to use 'Time' uniformly, as that's what X uses.
19108 This makes the code easier to follow, and makes it easier to catch
19109 integer overflow bugs such as Bug#8664.
19110 * frame.c (Fmouse_position, Fmouse_pixel_position):
19111 Use Time, not unsigned long, for user-interface timestamps.
19112 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19113 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19114 * keyboard.h (last_event_timestamp): Likewise.
19115 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19116 * menu.h (xmenu_show): Likewise.
19117 * term.c (term_mouse_position): Likewise.
19118 * termhooks.h (struct input_event.timestamp): Likewise.
19119 (struct terminal.mouse_position_hook): Likewise.
19120 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19121 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19122 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19123 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19124 what it was before.
19125 * menu.h, termhooks.h: Include "systime.h", for Time.
19127 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19128 Don't assume that the difference between two unsigned long values
19129 can fit into an integer. At this point, we know button_down_time
19130 <= event->timestamp, so the difference must be nonnegative, so
19131 there's no need to cast the result if double-click-time is
19132 nonnegative, as it should be; check that it's nonnegative, just in
19133 case. This bug is triggered when events are more than 2**31 ms
19134 apart (about 25 days). (Bug#8664)
19136 * xselect.c (last_event_timestamp): Remove duplicate decl.
19137 (x_own_selection): Remove needless cast to unsigned long.
19139 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19140 that always fit in int. Use a sentinel instead of a counter, to
19141 avoid a temp and to allay GCC's concerns about possible int overflow.
19142 * frame.h (struct frame): Use int for menu_bar_items_used
19143 instead of EMACS_INT, since it always fits in int.
19145 * menu.c (grow_menu_items): Check for int overflow.
19147 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19149 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19150 Before, the code was not consistent. These values cannot exceed
19151 2**31 - 1 so there's no need to make them unsigned.
19152 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19153 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19154 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19156 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19158 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19159 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19160 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19161 presumably because the widths might not match.
19163 * window.c (size_window): Avoid needless test at loop start.
19165 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19167 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19169 2011-05-12 Drew Adams <drew.adams@oracle.com>
19171 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19173 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19175 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19176 `width' to `bar_area_x' and `bar_area_width', respectively.
19177 (x_scroll_run): Take account of fringe background extension.
19179 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19180 Rename local vars `left' and `width' to `bar_area_x' and
19181 `bar_area_width', respectively.
19182 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19183 background extension.
19185 2011-05-10 Jim Meyering <meyering@redhat.com>
19187 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19189 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19191 * image.c (Finit_image_library): Return t for built-in image types,
19192 like pbm and xbm. (Bug#8640)
19194 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19196 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19198 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19200 * w32console.c (Fset_screen_color): Doc fix.
19201 (Fget_screen_color): New function.
19202 (syms_of_ntterm): Defsubr it.
19204 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19205 unlink the temporary file if Fcall_process didn't create it in the
19207 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19208 child process will be redirected to a file specified with `:file'.
19209 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19210 cue to call_process_cleanup not to close that handle.
19212 2011-05-07 Ben Key <bkey76@gmail.com>
19214 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19215 one of two shell specific rules, either bootstrap-temacs-CMD or
19216 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19217 to the previous implementation of the bootstrap-temacs rule.
19218 The bootstrap-temacs-CMD rule is similar to the previous
19219 implementation of the bootstrap-temacs rule except that it
19220 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19223 These changes, along with some changes to nt/configure.bat,
19224 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19225 earlier fix to add support for --cflags and --ldflags options
19226 that include quotes so that it works whether make uses cmd or
19229 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19231 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19232 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19234 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19235 a string. Handle both cases.
19236 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19237 (Fdbus_register_method): Use Qinvalid_function.
19239 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19241 * makefile.w32-in: Update dependencies.
19242 (LISP_H): Add inttypes.h and stdin.h.
19243 (PROCESS_H): Add unistd.h.
19245 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19247 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19248 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19250 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19252 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19254 * term.c (vfatal): Remove stray call to va_end.
19255 It's not needed and the C Standard doesn't allow it here anyway.
19257 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19258 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19260 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19263 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19265 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19267 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19269 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19271 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19273 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19274 * charset.c (Fdefine_charset_internal): Don't initialize
19275 charset.code_space[15]. The value was garbage, on hosts with
19276 32-bit int (Bug#8600).
19278 * lread.c (read_integer): Be more consistent with string-to-number.
19279 Use string_to_number to do the actual conversion; this avoids
19280 rounding errors and fixes some other screwups. Without this fix,
19281 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19282 (digit_to_number): Move earlier, for benefit of read_integer.
19283 Return -1 if the digit is out of range for the base, -2 if it is
19284 not a digit in any supported base. (Bug#8602)
19286 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19288 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19289 to match comment at start of function. This also removes a
19290 GCC warning about overflow in a 32+64-bit port.
19292 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19294 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19295 Reported by Stefan Monnier in
19296 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19297 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19298 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19300 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19301 (EMACS_UINTPTR): Likewise, with uintptr_t.
19303 * lisp.h: Prefer 64-bit EMACS_INT if available.
19304 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19305 on 32-bit hosts that have 64-bit int, so that they can access
19307 However, temporarily disable this change unless the temporary
19308 symbol WIDE_EMACS_INT is defined.
19310 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19312 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19313 This removes an assumption that EMACS_INT and long are the same
19314 width as pointers. The assumption is true for Emacs porting targets
19315 now, but we want to make other targets possible.
19316 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19317 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19318 In the rest of the code, change types of integers that hold casted
19319 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19320 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19321 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19322 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19323 No need to cast type when ORing.
19324 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19325 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19326 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19327 assume EMACS_INT is the same width as char *.
19328 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19329 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19330 Remove no-longer-needed casts.
19331 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19332 (xg_tool_bar_help_callback, xg_make_tool_item):
19333 Use EMACS_INTPTR to hold an integer
19334 that will be cast to void *; this can avoid a GCC warning
19335 if EMACS_INT is not the same width as void *.
19336 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19337 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19338 (current_message_1, set_message_1):
19339 Use a local to convert to proper width without a cast.
19340 * xmenu.c (dialog_selection_callback): Likewise.
19342 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19343 Also, don't assume VALBITS / RAND_BITS is less than 5,
19344 and don't rely on undefined behavior when shifting a 1 left into
19346 * lisp.h (get_random): Change signature to match.
19348 * lread.c (hash_string): Use size_t, not int, for hash computation.
19349 Normally we prefer signed values; but hashing is special, because
19350 it's better to use unsigned division on hash table sizes so that
19351 the remainder is nonnegative. Also, size_t is the natural width
19352 for hashing into memory. The previous code used 'int', which doesn't
19353 retain enough info to hash well into very large tables.
19354 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19356 * dbusbind.c: Don't possibly lose pointer info when converting.
19357 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19358 Use XPNTR rather than XHASH, so that the high-order bits of
19359 the pointer aren't lost when converting through void *.
19361 * eval.c (Fautoload): Don't double-shift a pointer.
19363 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19365 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19367 * gnutls.c (DEF_GNUTLS_FN):
19368 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19370 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19372 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19375 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19377 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19378 New version that can reserve upto 2GB of heap space.
19380 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19382 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19384 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19386 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19387 `gnutls_certificate_set_x509_key_file'.
19389 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19391 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19392 Update dependencies.
19394 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19396 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19397 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19398 Remove unused parameter `fildes'.
19399 * process.c (read_process_output, send_process): Don't pass it.
19401 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19403 Fix previous change: the library cache is defined in w32.c.
19404 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19405 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19407 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19409 Implement dynamic loading of GnuTLS on Windows.
19411 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19412 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19413 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19416 * gnutls.c (Qgnutls_dll): Define.
19417 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19418 (gnutls_*): Declare function pointers.
19419 (init_gnutls_functions): New function to initialize function pointers.
19420 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19421 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19422 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19423 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19424 (emacs_gnutls_write, emacs_gnutls_read)
19425 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19426 (Fgnutls_available_p): New function.
19427 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19428 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19429 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19431 * image.c: Include w32.h.
19432 (Vimage_type_cache): Delete.
19433 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
19434 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19435 (w32_delayed_load): Move to w32.c.
19437 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19439 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19440 (w32_delayed_load): Move from image.c. When loading a library, record
19441 its filename in the :loaded-from property of the library id.
19442 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19443 Initialize and staticpro them.
19444 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19446 * process.c: Include lisp.h before w32.h, not after.
19447 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19448 instead of gnutls_record_check_pending.
19450 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19452 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19454 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19455 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19458 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19460 * xterm.c (x_set_frame_alpha): Do not set property on anything
19461 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19463 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19465 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19467 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19469 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19470 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
19471 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

19476 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19477 (Qgnutls_bootprop_callbacks_verify): Make static.
19479 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19481 * callproc.c: Indentation fixup.
19483 * sysdep.c (wait_for_termination_1): Make static.
19484 (wait_for_termination, interruptible_wait_for_termination):
19485 Move after wait_for_termination_1.
19487 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19489 * sysdep.c (interruptible_wait_for_termination): New function
19490 which is like wait_for_termination, but allows keyboard
19493 * callproc.c (Fcall_process): Add (:file "file") as an option for
19495 (Fcall_process_region): Ditto.
19497 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19499 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19500 rather than `XVECTOR (FOO)->size'.
19502 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19503 inttypes.h, as a gnulib replacement is used if it not available in
19506 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19508 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19509 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19510 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19512 * coding.c (coding_alloc_by_realloc): Error out if destination
19513 will grow beyond MOST_POSITIVE_FIXNUM.
19514 (decode_coding_emacs_mule): Abort if there isn't enough place in
19515 charbuf for the composition carryover bytes. Reserve an extra
19516 space for up to 2 characters produced in a loop.
19517 (decode_coding_iso_2022): Abort if there isn't enough place in
19518 charbuf for the composition carryover bytes.
19520 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19522 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19523 aborting when %lld or %lll format is passed.
19524 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19525 %llo or %llx format is passed. (Bug#8545)
19527 * window.c (window_scroll_line_based): Use a marker instead of
19528 simple variables to record original value of point. (Bug#7952)
19530 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19531 produced by %s or %c overflows available buffer space. (Bug#8545)
19533 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19535 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19536 (SIZE_MAX): Move defn after all includes, as they might #define it.
19538 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19540 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19542 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19544 * keyboard.c (Qdelayed_warnings_hook): Define.
19545 (command_loop_1): Run `delayed-warnings-hook'
19546 if Vdelayed_warnings_list is non-nil.
19547 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19548 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19550 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19552 * doprnt.c (doprnt): Don't return value smaller than the buffer
19553 size if the message was truncated. (Bug#8545).
19555 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19557 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19558 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19560 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19562 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19564 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19566 * makefile.w32-in: Update dependencies.
19568 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19570 Improve `doprnt' and its usage. (Bug#8545)
19571 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19572 `format_end'. Remove support for %l as a conversion specifier.
19573 Don't use xrealloc. Improve diagnostics when the %l size modifier
19574 is used. Update the commentary.
19576 * eval.c (verror): Simplify calculation of size_t.
19578 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19581 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19583 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19586 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19588 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19589 This makes this file independent of the recent pseudovector change.
19591 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19593 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19595 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19596 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19597 Remove unused local.
19598 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19600 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19601 GCC 4.6.0 optimizes based on type-based alias analysis.
19602 For example, if b is of type struct buffer * and v of type struct
19603 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19604 != &v->size, and therefore "v->size = 1; b->size = 2; return
19605 v->size;" must therefore return 1. This assumption is incorrect
19606 for Emacs, since it type-puns struct Lisp_Vector * with many other
19607 types. To fix this problem, this patch adds a new type struct
19608 vectorlike_header that documents the constraints on layout of vectors
19609 and pseudovectors, and helps optimizing compilers not get fooled
19610 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19611 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19612 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19614 (XSETPVECTYPE): Rewrite in terms of new macro.
19615 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19616 This is a bit clearer, and further avoids the possibility of
19617 undesirable aliasing.
19618 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19619 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19620 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19621 since Lisp_Subr is a special case (no "next" field).
19622 (ASIZE): Now uses header.size rather than size.
19623 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19624 to avoid the hassle of writing XVECTOR (foo)->header.size.
19625 (struct vectorlike_header): New type.
19626 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19627 object, to help avoid aliasing.
19628 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19629 (SUBRP): Likewise, since Lisp_Subr is a special case.
19630 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19631 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19632 (struct Lisp_Hash_Table): Combine first two members into a single
19633 struct vectorlike_header member. All uses of "size" and "next" members
19634 changed to be "header.size" and "header.next".
19635 * buffer.h (struct buffer): Likewise.
19636 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19637 * frame.h (struct frame): Likewise.
19638 * process.h (struct Lisp_Process): Likewise.
19639 * termhooks.h (struct terminal): Likewise.
19640 * window.c (struct save_window_data, struct saved_window): Likewise.
19641 * window.h (struct window): Likewise.
19642 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19643 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19644 * buffer.c (init_buffer_once): Likewise.
19645 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19647 * process.c (Fformat_network_address): Use local var for size,
19650 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19652 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19653 * data.c (atof): Remove decl; no longer used or needed.
19654 (digit_to_number): Move to lread.c.
19655 (Fstring_to_number): Use new string_to_number function, to be
19656 consistent with how the Lisp reader treats infinities and NaNs.
19657 Do not assume that floating-point numbers represent EMACS_INT
19658 without losing information; this is not true on most 64-bit hosts.
19659 Avoid double-rounding errors, by insisting on integers when
19660 parsing non-base-10 numbers, as the documentation specifies.
19661 * lisp.h (string_to_number): New decl, replacing ...
19662 (isfloat_string): Remove.
19663 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19664 (read1): Do not accept +. and -. as integers; this
19665 appears to have been a coding error. Similarly, do not accept
19666 strings like +-1e0 as floating point numbers. Do not report
19667 overflow for integer overflows unless the base is not 10 which
19668 means we have no simple and reliable way to continue.
19669 Break out the floating-point parsing into a new
19670 function string_to_number, so that Fstring_to_number parses
19671 floating point numbers consistently with the Lisp reader.
19672 (digit_to_number): Move here from data.c. Make it static inline.
19673 (E_CHAR, EXP_INT): Remove, replacing with ...
19674 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19675 (string_to_number): New function, replacing isfloat_string.
19676 This function checks for valid syntax and produces the resulting
19677 Lisp float number too. Rework it so that string-to-number
19678 no longer mishandles examples like "1.0e+". Use strtoumax,
19679 so that overflow for non-base-10 numbers is reported only when
19680 there's no portable and simple way to convert to floating point.
19682 * textprop.c (set_text_properties_1): Rewrite for clarity,
19683 and to avoid GCC warning about integer overflow.
19685 * intervals.h (struct interval): Use EMACS_INT for members
19686 where EMACS_UINT might cause problems. See
19687 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19688 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19689 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19691 (offset_intervals): Tell GCC not to worry about length overflow
19692 when negating a negative length.
19694 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19695 (overrun_check_free): Likewise.
19697 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19698 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19701 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19702 (gnutls_make_error): Rename local to avoid shadowing.
19703 (gnutls_emacs_global_deinit): ifdef out; not used.
19704 (Fgnutls_boot): Use const for pointer to readonly storage.
19705 Comment out unused local. Fix pointer signedness problems.
19707 * lread.c (openp): Don't stuff size_t into an 'int'.
19708 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19709 about possible signed overflow.
19711 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19712 (GDK_KEY_g): Don't define if already defined.
19713 (xg_prepare_tooltip): Avoid pointer signedness problem.
19714 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19716 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19717 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19719 * xfns.c (Fx_window_property): Simplify a bit,
19720 to make a bit faster and to avoid GCC 4.6.0 warning.
19721 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19723 * fns.c (internal_equal): Don't assume size_t fits in int.
19725 * alloc.c (compact_small_strings): Tighten assertion a little.
19727 Replace pEd with more-general pI, and fix some printf arg casts.
19728 * lisp.h (pI): New macro, generalizing old pEd macro to other
19729 conversion specifiers. For example, use "...%"pI"d..." rather
19730 than "...%"pEd"...".
19731 (pEd): Remove. All uses replaced with similar uses of pI.
19732 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19733 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19734 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19735 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19736 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19737 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19738 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19740 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19741 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19742 * print.c (safe_debug_print, print_object): Likewise.
19743 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19745 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19746 avoiding the 0 flag, which is not portable.
19747 * process.c (Fmake_network_process): Use pI to avoid cast.
19748 * region-cache.c (pp_cache): Likewise.
19749 * xdisp.c (decode_mode_spec): Likewise.
19750 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19751 behavior on 64-bit hosts with printf arg.
19752 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19753 (x_stop_queuing_selection_requests): Likewise.
19754 (x_get_window_property): Don't truncate byte count to an 'int'
19757 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19758 here, since it parses constructs like leading '-' and spaces,
19759 which are not wanted; and it overflows with large numbers.
19760 Instead, simply match F[0-9]+, which is what is wanted anyway.
19762 * alloc.c: Remove unportable assumptions about struct layout.
19763 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19764 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19765 (allocate_vectorlike, make_pure_vector): Use the new macros,
19766 plus offsetof, to remove unportable assumptions about struct layout.
19767 These assumptions hold on all porting targets that I know of, but
19768 they are not guaranteed, they're easy to remove, and removing them
19769 makes further changes easier.
19771 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19772 This doesn't fix a bug but makes the code clearer.
19773 (string_overrun_cookie): Now const. Use initializers that
19774 don't formally overflow signed char, to avoid warnings.
19775 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19776 can cause Emacs to crash when string overrun checking is enabled.
19777 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19778 multiple of sizeof (EMACS_INT); it need not be, if
19779 alignof(EMACS_INT) < sizeof (EMACS_INT).
19780 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19782 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19786 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19788 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19789 supposed to be handshaking. (Bug#8556)
19790 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19792 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19794 * lisp.h (Qdebug): List symbol.
19795 * eval.c (Qdebug): Restore global linkage.
19796 * keyboard.c (debug-on-event): New variable.
19797 (handle_user_signal): Break into debugger when debug-on-event
19798 matches the current signal symbol.
19800 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19802 * alloc.c (check_sblock, check_string_bytes)
19803 (check_string_free_list): Convert to standard C.
19805 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19807 * w32.c (emacs_gnutls_push): Fix typo.
19809 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19811 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19812 "cast to pointer from integer of different size".
19814 Improve doprnt and its use in verror. (Bug#8545)
19815 * doprnt.c (doprnt): Document the set of format control sequences
19816 supported by the function. Use SAFE_ALLOCA instead of always
19819 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19820 is one byte too soon. Don't use xrealloc; instead xfree and
19823 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19825 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19828 * gnutls.c: Renamed global_initialized to
19829 gnutls_global_initialized. Added internals for the
19830 :verify-hostname-error, :verify-error, and :verify-flags
19831 parameters of `gnutls-boot' and documented those parameters in the
19832 docstring. Start callback support.
19833 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19834 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19835 on error. Return error code.
19836 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19837 (emacs_gnutls_read): Likewise.
19838 (Fgnutls_boot): Return handshake error code.
19839 (emacs_gnutls_handle_error): New function.

19895 changes in globals.h immediately force recompilation.
19896 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19897 $(CURDIR)/s/ms-w32.h.
19898 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

19902 <char-direction-table>: Deleted.
19904 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19906 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19907 * doprnt.c: Include limits.h.
19908 (SIZE_MAX): New macro.
19909 (doprnt): Return a size_t value. 2nd arg is now size_t.
19910 Many local variables are now size_t instead of int or unsigned.
19911 Improve overflow protection. Support `l' modifier for integer
19912 conversions. Support %l conversion. Don't assume an EMACS_INT
19913 argument for integer conversions and for %c.
19915 * lisp.h (doprnt): Restore prototype.
19917 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19918 $(SRC)/character.h.
19920 * Makefile.in (base_obj): Add back doprnt.o.
19922 * deps.mk (doprnt.o): Add back prerequisites.
19923 (callint.o): Depend on character.h.
19925 * eval.c (internal_lisp_condition_case): Include the handler
19926 representation in the error message.
19927 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19928 when breaking from the loop.
19930 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19932 * callint.c (Fcall_interactively): When displaying error message
19933 about invalid control letter, pass the character's codepoint, not
19934 a pointer to its multibyte form. Improve display of the character
19935 in octal and display also its hex code.
19937 * character.c (char_string): Use %x to display the (unsigned)
19938 codepoint of an invalid character, to avoid displaying a bogus
19941 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19942 `error', not SYMBOL_NAME itself.
19944 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19945 character arguments to `error'.
19947 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19948 to `error' in error message about FINAL_CHAR argument. Make sure
19949 FINAL_CHAR is a character, and use %c when it is passed as
19950 argument to `error'.
19952 2011-04-23 Eli Zaretskii <eliz@gnu.org>

20140 ns_descriptor_to_entity that were caused by using free to
20141 deallocate memory blocks that were allocated by xmalloc (via
20142 xstrdup). This caused Emacs to crash when compiled with

20162 (emacs_read, emacs_write): Use it.
20163 * process.c (send_process): Adjust to the new signatures of
20164 emacs_write and emacs_gnutls_write. Do not attempt to store

20494 * lisp.h: Remove these decls.
20496 * buffer.c (buffer_count): Remove unused var.
20498 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20499 so that it's not optimized away.
20500 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20501 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20502 exported only to the debugger.
20504 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20505 * atimer.h (run_all_atimers): Remove; not exported.
20507 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20508 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20509 was inaccessible from Lisp.
20510 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20511 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20513 alloc.c: Import and export fewer symbols, and remove unused items.
20514 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20516 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20517 it's not optimized away by whole-program optimization.
20518 (message_enable_multibyte, free_misc): Remove.
20519 (catchlist, handlerlist, mark_backtrace):
20520 Declare only if BYTE_MARK_STACK.

20529 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20530 (mark_backtrace): Define only if BYTE_MARK_STACK.
20531 * xdisp.c (message_enable_multibyte): Now static.
20533 Declare Lisp_Object Q* variables to be 'static' if not exported.
20534 This makes it easier for human readers (and static analyzers)
20535 to see whether these variables are used from other modules.
20536 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20537 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20538 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

20546 Remove decls of unexported vars.
20547 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20549 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20551 Make Emacs functions such as Fatom 'static' by default.
20552 This makes it easier for human readers (and static analyzers)
20553 to see whether these functions can be called from other modules.
20554 DEFUN now defines a static function. To make the function external
20555 so that it can be used in other C modules, use the new macro DEFUE.
20556 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20557 (Finit_image_library):
20558 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20559 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20560 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20561 Remove decls, since these functions are now static.
20562 (Funintern, Fget_internal_run_time): New decls, since these functions
20563 were already external.
20565 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

20573 Mark functions with DEFUE instead of DEFUN,
20574 if they are used in other modules.
20575 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20576 decls for now-static functions.
20577 * buffer.h (Fdelete_overlay): Remove decl.

20587 * image.c (Finit_image_library): New forward static decl.
20588 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20589 * intervals.h (Fprevious_property_change):
20590 (Fremove_list_of_text_properties): Remove decls.
20591 * keyboard.c (Fthis_command_keys): Remove decl.
20592 (Fcommand_execute): New forward static decl.

20613 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20615 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20616 when at ZV. (Bug#8487)
20618 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20620 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20623 * sound.c (sound_cleanup, alsa_close): Likewise.
20624 * termcap.c (tgetent): Likewise.

20626 * xsettings.c (read_and_apply_settings): Likewise.
20628 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20629 (overrun_check_free): Protoize.
20631 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20633 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20634 since callers should never pass a negative size.
20635 Change the signature to match that of plain 'read' and 'write'; see
20636 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20637 * lisp.h: Update prototypes of emacs_write and emacs_read.
20639 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20641 * xdisp.c (redisplay_window): Don't try to determine the character
20642 position of the scroll margin if the window start point w->startp
20643 is outside the buffer's accessible region. (Bug#8468)
20645 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20647 Fix write-region and its subroutines for buffers > 2GB.
20648 * fileio.c (a_write, e_write): Modify declaration of arguments and
20649 local variables to support buffers larger than 2GB.
20650 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20652 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20653 argument, local variables, and return value.
20655 * lisp.h: Update prototypes of emacs_write and emacs_read.
20657 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20659 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20661 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20663 Fix more problems found by GCC 4.6.0's static checks.
20665 * xdisp.c (vmessage): Use a better test for character truncation.
20667 * charset.c (load_charset_map): <, not <=, for optimization,
20668 and to avoid potential problems with integer overflow.
20669 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20670 * casetab.c (set_identity, shuffle): Likewise.
20671 * editfns.c (Fformat): Likewise.
20672 * syntax.c (skip_chars): Likewise.
20674 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20675 This also lets GCC 4.6.0 generate slightly better loop code.
20677 * callint.c (Fcall_interactively): <, not <=, for optimization.
20678 (Fcall_interactively): Count the number of arguments produced,
20679 not the number of arguments given. This is simpler and lets GCC
20680 4.6.0 generate slightly better code.
20682 * ftfont.c: Distingish more carefully between FcChar8 and char.
20683 The previous code passed unsigned char * to a functions like
20684 strlen and xstrcasecmp that expect char *, which does not
20685 conform to the C standard.
20686 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20687 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20688 char * when the C standard requires it.
20690 * keyboard.c (read_char): Remove unused var.
20692 * eval.c: Port to Windows vsnprintf (Bug#8435).
20693 Include <limits.h>.
20694 (SIZE_MAX): Define if the headers do not.
20695 (verror): Do not give up if vsnprintf returns a negative count.
20696 Instead, grow the buffer. This ports to Windows vsnprintf, which
20697 does not conform to C99. Problem reported by Eli Zaretskii.
20698 Also, simplify the allocation scheme, by avoiding the need for
20699 calling realloc, and removing the ALLOCATED variable.
20701 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20703 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20704 But keep the doprint source code for now, as we might revamp it
20705 and use it again (Bug#8435).
20706 * lisp.h (doprnt): Remove.
20707 * Makefile.in (base_obj): Remove doprnt.o.
20708 * deps.mk (doprnt.o): Remove.
20710 error: Print 32- and 64-bit integers portably (Bug#8435).
20711 Without this change, on typical 64-bit hosts error ("...%d...", N)
20712 was used to print both 32- and 64-bit integers N, which relied on
20713 undefined behavior.
20714 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20715 * lisp.h (error, verror): Mark as printf-like functions.
20716 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20717 Report overflow in size calculations when allocating printf buffer.
20718 Do not truncate output string at its first null byte.
20719 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20720 Truncate the output at a character boundary, since vsnprintf does not
20722 * charset.c (check_iso_charset_parameter): Convert internal
20723 character to string before calling 'error', since %c now has the
20725 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20726 overflow when computing char to be passed to 'error'. Do not
20727 pass Lisp_Object to 'error'; pass the integer instead.
20728 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20729 formatted with plain %d.
20731 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20733 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20735 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20737 * xterm.c (x_catch_errors): Remove duplicate declaration.
20739 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20741 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20743 2011-04-10 Jim Meyering <meyering@redhat.com>
20745 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20746 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20747 return ssize_t not "int", and use size_t as the buffer length.
20748 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20749 * gnutls.h: Update declarations.
20750 * process.c (read_process_output): Use ssize_t, to match.
20751 (send_process): Likewise.
20753 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20755 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20757 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20759 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20760 Use unsigned char, to match FcChar8 type definition.
20762 * xterm.c (handle_one_xevent):
20763 * xmenu.c (create_and_show_popup_menu):
20764 * xselect.c (x_decline_selection_request)
20765 (x_reply_selection_request): Avoid type-punned deref of X events.
20767 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20769 Fix some uses of `int' instead of EMACS_INT.
20770 * search.c (string_match_1, fast_string_match)
20771 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20772 (scan_buffer, find_next_newline_no_quit)
20773 (find_before_next_newline, search_command, Freplace_match)
20774 (Fmatch_data): Make some `int' variables be EMACS_INT.
20776 * xdisp.c (display_count_lines): 3rd argument and return value now
20777 EMACS_INT. All callers changed.
20778 (pint2hrstr): Last argument is now EMACS_INT.
20780 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20781 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20782 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20793 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20794 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20796 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20797 (encode_invocation_designation): Last argument P_NCHARS is now
20799 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20800 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20802 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20805 * ccl.c (Fccl_execute_on_string): Declare some variables
20808 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20810 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20812 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20814 * process.c (Fformat_network_address): Doc fix.
20816 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20818 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20820 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20822 * keyboard.c (read_char): Call Lisp function help-form-show,
20823 instead of using internal_with_output_to_temp_buffer.
20824 (Qhelp_form_show): New var.
20825 (syms_of_keyboard): Use DEFSYM macro.
20827 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20834 (list_processes_1): Delete.
20836 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20838 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20840 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20842 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20844 Fix more problems found by GCC 4.6.0's static checks.

20859 printf-like functions.
20860 (tiff_load): Add casts to remove these marks before passing them
20861 to system-supplied API.
20863 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20865 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20866 This avoids several warnings with gcc -Wstrict-overflow.
20867 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20868 directly, rather than having caller test rule sign. This avoids
20869 some unnecessary tests.
20870 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20871 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20872 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20874 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20875 (xfont_open): Avoid unnecessary tests.
20877 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20879 * composite.h, composite.c (composition_gstring_put_cache):
20880 Use EMACS_INT, not int, for length.
20882 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20883 breaking out part of COMPOSITION_DECODE_RULE.
20884 (COMPOSITION_DECODE_RULE): Use it.
20885 * composite.c (get_composition_id): Remove unused local vars,
20886 by using the new macro.
20888 * textprop.c (set_text_properties_1): Change while to do-while,
20889 since the condition is always true at first.
20891 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20892 (interval_deletion_adjustment): Return unsigned value.
20895 * process.c (list_processes_1, create_pty, read_process_output):
20896 (exec_sentinel): Remove vars that were set but not used.
20897 (create_pty): Remove unnecessary "volatile"s.
20898 (Fnetwork_interface_info): Avoid possibility of int overflow.
20899 (read_process_output): Do adaptive read buffering even if carryover.
20900 (read_process_output): Simplify nbytes computation if buffered.

20904 * syntax.c (scan_words): Remove var that was set but not used.
20905 (update_syntax_table): Use unsigned instead of int.
20907 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20908 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20909 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20911 * print.c (print_error_message): Avoid int overflow.
20913 * font.c (font_list_entities): Redo for clarity,
20914 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20916 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20917 (font_score): Avoid potential overflow in diff calculation.
20919 * fns.c (substring_both): Remove var that is set but not used.
20920 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20922 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20924 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20925 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20926 can always succeed if overflow has undefined behavior.
20928 * search.c (boyer_moore, wordify): Remove vars set but not used.
20929 (wordify): Omit three unnecessary tests.
20931 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20932 All callers changed. This avoids the need for an unused var.
20934 * casefiddle.c (casify_region): Remove var that is set but not used.
20936 * dired.c (file_name_completion): Remove var that is set but not used.
20938 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20940 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20941 (Finsert_file_contents): Remove unnecessary code checking fd.
20943 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20944 Check for integer overflow on size calculations.
20946 * buffer.c (Fprevious_overlay_change): Remove var that is set
20949 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20950 Remove vars that are set but not used.
20951 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20952 (timer_check_2): Mark vars as initialized.
20954 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20956 * image.c (lookup_image): Remove var that is set but not used.
20957 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20959 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20960 that are set but not used.
20962 * xfns.c (make_invisible_cursor): Don't return garbage
20963 if XCreateBitmapFromData fails (Bug#8410).
20965 * xselect.c (x_get_local_selection, x_handle_property_notify):
20966 Remove vars that are set but not used.
20968 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20969 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20971 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20972 Remove var that is set but not used.
20973 (scroll_bar_windows_size): Now size_t, not int.
20974 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20975 Check for overflow.
20977 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20978 (map_tty_color) [!defined MSDOS]: Likewise.
20980 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20982 * coding.c: Remove vars that are set but not used.
20983 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20984 All callers changed.
20985 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20986 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20987 (decode_coding_charset): Remove vars that are set but not used.
20989 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20990 that is set but not used.
20992 * print.c (print_object): Remove var that is set but not used.
20994 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20995 The gnulib version avoids calling malloc in the usual case,
20996 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20997 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20998 * filelock.c (current_lock_owner): Likewise.
20999 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21000 * sysdep.c: Include allocator.h, careadlinkat.h.
21001 (emacs_no_realloc_allocator): New static constant.
21002 (emacs_readlink): New function.
21003 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21004 ../lib/careadlinkat.h.
21006 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21008 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21009 first non-nil return value).
21011 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21013 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21014 if not defined (Bug#8403).
21016 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21018 * xdisp.c (display_count_lines): Remove parameter `start',
21019 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21020 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21021 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21023 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21024 and thereabouts. All callers changed.
21025 (get_per_char_metric): Remove parameter `f', unused since
21026 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21028 2011-04-02 Jim Meyering <meyering@redhat.com>
21030 do not dereference NULL upon failed strdup
21031 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21032 (ns_get_family): Likewise.
21034 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21036 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21038 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21040 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21043 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21045 Add lexical binding.
21047 * window.c (Ftemp_output_buffer_show): New fun.
21048 (Fsave_window_excursion):
21049 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21051 * lread.c (lisp_file_lexically_bound_p): New function.
21052 (Fload): Bind Qlexical_binding.
21053 (readevalloop): Remove `evalfun' arg.
21054 Bind Qinternal_interpreter_environment.
21055 (Feval_buffer): Bind Qlexical_binding.
21056 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21058 (syms_of_lread): Declare `lexical-binding'.
21060 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21062 * keyboard.c (eval_dyn): New fun.
21063 (menu_item_eval_property): Use it.
21065 * image.c (parse_image_spec): Use Ffunctionp.
21067 * fns.c (concat, mapcar1): Accept byte-code-functions.
21069 * eval.c (Fsetq): Handle lexical vars.
21070 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21071 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21072 (FletX, Flet): Obey lexical binding.
21073 (Fcommandp): Handle closures.
21074 (Feval): New `lexical' arg.
21075 (eval_sub): New function extracted from Feval. Use it almost
21076 everywhere where Feval was used. Look up vars in lexical env.
21078 (Ffunctionp): Move from subr.el.
21079 (Ffuncall): Handle closures.
21080 (apply_lambda): Remove `eval_flags'.
21081 (funcall_lambda): Handle closures and new byte-code-functions.
21082 (Fspecial_variable_p): New function.
21083 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21084 but without exporting it to Lisp.
21086 * doc.c (Fdocumentation, store_function_docstring):
21087 * data.c (Finteractive_form): Handle closures.
21089 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21092 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21094 (exec_byte_code): New function extracted from Fbyte_code to handle new
21095 calling convention for byte-code-functions. Add new byte-codes.
21097 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21099 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21101 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21103 * xdisp.c (redisplay_internal): Fix prototype.
21105 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21107 * xdisp.c (SCROLL_LIMIT): New macro.
21108 (try_scrolling): Use it when setting scroll_limit.
21109 Limit scrolling to 100 screen lines.
21110 (redisplay_window): Even when falling back on "recentering",
21111 position point in the window according to scroll-conservatively,
21112 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21114 (try_scrolling): When point is above the window, allow searching
21115 as far as scroll_max, or one screenful, to compute vertical
21116 distance from PT to the scroll margin position. This prevents
21117 try_scrolling from unnecessarily failing when
21118 scroll-conservatively is set to a value slightly larger than the
21119 window height. Clean up the case of PT below the margin at bottom
21120 of window: scroll_max can no longer be INT_MAX. When aggressive
21121 scrolling is in use, don't let point enter the opposite scroll
21122 margin as result of the scroll.
21123 (syms_of_xdisp) <scroll-conservatively>: Document the
21124 threshold of 100 lines for never-recentering scrolling.
21126 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21128 * dispextern.h (move_it_by_lines):
21129 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21130 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21131 (message_log_check_duplicate): Remove parameters `prev_bol' and
21132 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21133 (redisplay_internal): Remove parameter `preserve_echo_area',
21134 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21136 * indent.c (Fvertical_motion):
21137 * window.c (window_scroll_pixel_based, Frecenter):
21138 Don't pass `need_y_p' to `move_it_by_lines'.
21140 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21142 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21143 steal a few bits to be more compact.
21144 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21145 Remove unneeded casts.
21147 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21149 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21151 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21152 binding" message (bug#7967).
21154 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21156 Fix more problems found by GCC 4.6.0's static checks.
21158 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21159 Remove unused local var.
21161 * editfns.c (Fmessage_box): Remove unused local var.
21163 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21164 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21165 Omit unused local vars.
21166 * window.c (shrink_windows): Omit unused local var.
21167 * menu.c (digest_single_submenu): Omit unused local var.
21168 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21169 Omit unused local var.
21171 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21172 Don't assume string length fits in int.
21173 (keyremap_step, read_key_sequence): Use size_t for sizes.
21174 (read_key_sequence): Don't check last_real_key_start redundantly.
21176 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21177 instead of alloca (Bug#8344).
21179 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21180 (Fbacktrace_frame): Don't assume nframes fits in int.
21182 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21184 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21187 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21189 * cm.c (calccost): Turn while-do into do-while, for clarity.
21191 * keyboard.c (syms_of_keyboard): Use the same style as later
21192 in this function when indexing through an array. This also
21193 works around GCC bug 48267.
21195 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21197 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21199 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21200 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21202 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21203 This avoids undefined behavior on integer overflow, and is a bit
21204 more convenient anyway since it is compared to a size_t variable.
21206 Variadic C functions now count arguments with size_t, not int.
21207 This avoids an unnecessary limitation on 64-bit machines, which
21208 caused (substring ...) to crash on large vectors (Bug#8344).
21209 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21210 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21218 * fns.c (concat): Likewise.
21219 * frame.c (x_set_frame_parameters): Likewise.
21220 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21221 0 if not found, not -1. All callers changed.
21223 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21224 (stack_copy_size): Now size_t, not int.
21225 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21227 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21229 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21230 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21231 All callers changed.
21233 * lisp.h (multibyte_char_to_unibyte):
21234 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21235 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21243 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21245 * keyboard.c (safe_run_hook_funcall): New function.
21246 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21247 don't set the hook to nil, but remove the offending function instead.
21248 (Qcommand_hook_internal): Remove, unused.
21249 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21250 Vcommand_hook_internal.
21252 * eval.c (enum run_hooks_condition): Remove.
21253 (funcall_nil, funcall_not): New functions.
21254 (run_hook_with_args): Call each function through a `funcall' argument.
21255 Remove `cond' argument, now redundant.
21256 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21257 (Frun_hook_with_args_until_failure): Adjust accordingly.
21258 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

21264 * print.c (strout): Remove parameter `multibyte', unused since
21265 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21267 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21268 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21269 All callers changed.
21271 * w32.c (_wsa_errlist): Use braces for struct initializers.
21273 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21274 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21275 All callers changed.

21430 * buffer.c (Fkill_all_local_variables):
21431 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21433 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21434 unconditionally since it does the check itself.
21436 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21438 Fix more problems found by GCC 4.5.2's static checks.
21440 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21441 the first time through the loop, since we know p0 < p1 then.
21442 This also avoids a gcc -Wstrict-overflow warning.
21444 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21445 leading to a memory leak, possible in functions like
21446 load_charset_map_from_file that can allocate an unbounded number
21447 of objects (Bug#8318).
21449 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21450 that could (at least in theory) be that large.
21452 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21453 This is less likely to overflow, and avoids undefined behavior if
21454 overflow does occur. All callers changed. Use strtoul to scan
21455 for the unsigned long integer.
21456 (pint2hrstr): Simplify and tune code slightly.
21457 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21467 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21470 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21472 * process.c (Fmake_network_process): Use socklen_t, not int,
21473 where POSIX says socklen_t is required in portable programs.
21474 This fixes a porting bug on hosts like 64-bit HP-UX, where
21475 socklen_t is wider than int (Bug#8277).
21476 (Fmake_network_process, server_accept_connection):
21477 (wait_reading_process_output, read_process_output):
21480 * process.c: Rename or move locals to avoid shadowing.

21490 Make tparam.h and terminfo.c consistent.
21491 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21492 Include tparam.h instead, since it declares them.
21493 * cm.h (PC): Remove extern decl; tparam.h now does this.
21494 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21495 * terminfo.c: Include tparam.h, to check interfaces.
21496 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21497 (tparam): Adjust signature to match interface in tparam.h;
21498 this removes some undefined behavior. Check that outstring and len
21499 are zero, which they always are with Emacs.
21500 * tparam.h (PC, BC, UP): New extern decls.
21502 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21503 (xftfont_open): Rename locals to avoid shadowing.
21505 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

21517 * composite.c (composition_compute_stop_pos): Rename local to
21519 (composition_reseat_it): Remove unused locals.
21520 (find_automatic_composition, composition_adjust_point): Likewise.
21521 (composition_update_it): Mark var as initialized.
21522 (find_automatic_composition): Mark vars as initialized,
21523 with a FIXME (Bug#8290).

21527 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21528 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21529 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21530 to avoid shadowing.
21532 * textprop.c (property_change_between_p): Remove; unused.
21534 * intervals.c (interval_start_pos): Now static.
21536 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21542 Fix pointer signedness.
21543 (alsa_choose_format): Remove unused local var.
21544 (wav_play): Initialize a variable to 0, to prevent undefined
21545 behavior (Bug#8278).
21547 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21549 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21551 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21552 clobbering (Bug#8298).
21553 * sysdep.c (sys_subshell): Likewise.
21554 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21556 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21557 This should get cleaned up, so that child_setup has the
21558 same signature on all platforms.
21560 * callproc.c (call_process_cleanup): Now static.
21561 (relocate_fd): Rename locals to avoid shadowing.
21563 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21565 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21566 not to be necessary, and produces flickering.
21568 2011-03-20 Glenn Morris <rgm@gnu.org>
21570 * config.in: Remove file.
21572 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21574 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21575 are now in src/globals.h.
21576 (syms_of_minibuf): Remove spurious & from previous change.

21617 Define only if needed.
21619 * unexelf.c (unexec): Name an expression,
21620 to avoid gcc -Wbad-function-cast warning.
21621 Use a different way to cause a compilation error if anyone uses
21622 n rather than nn, a way that does not involve shadowing.
21623 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21625 * deps.mk (unexalpha.o): Remove; unused.
21627 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21694 (Ftranslate_region_internal, Fformat):
21695 Rename or remove local vars to avoid shadowing.

21698 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
21701 * lisp.h (eassert): Check that the argument compiles, even if
21702 ENABLE_CHECKING is not defined.
21704 * data.c (Findirect_variable): Name an expression, to avoid
21705 gcc -Wbad-function-cast warning.

21722 (Fmemory_limit): Cast sbrk's returned value to char *.

21748 (RETALLOC_IF): Define only if needed.
21749 (WORDCHAR_P): Likewise. This one is never needed, but is used
21750 only in a comment talking about a compiler bug, so put inside
21751 the #if 0 of that comment.
21752 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21753 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21782 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21784 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

21789 Rename locals to avoid shadowing.
21791 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

21797 and the new implementation with inline functions needs to have
21798 current_buffer in scope now, rather than later when the macros
21800 (downcase, upcase1): New static inline functions.
21801 (DOWNCASE, UPCASE1): Reimplement using these functions.
21802 This avoids undefined behavior in expressions like

21843 * buffer.c (fix_overlays_before): Mark locals as initialized.
21844 (fix_start_end_in_overlays): Likewise. This function should be
21845 simplified by using pointers-to-pointers, but that's a different

21848 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21849 (report_overlay_modification): Rename locals to avoid shadowing.

21854 to suppress a gcc -Wclobbered warning that does not seem to be right.
21855 (MAXPATHLEN): Define only if needed.
21857 * process.c (serial_open, serial_configure): Move decls from here ...
21858 * systty.h: ... to here, so that they can be checked.
21860 * fns.c (get_random, seed_random): Move extern decls from here ...
21861 * lisp.h: ... to here, so that they can be checked.
21863 * sysdep.c (reset_io): Now static.
21864 (wait_for_termination_signal): Remove; unused.
